Description

TECHNICAL FIELD

[0001] The present disclosure relates to a laundry treating apparatus. More specifically, the present disclosure relates to a laundry treating apparatus that performs a refreshing cycle that may perform at least one of deodorization, wrinkle removal, and sterilization of laundry by supplying at least one of air and steam to the laundry.BACKGROUND

[0002] A laundry treating apparatus refers to an apparatus developed to wash and dry laundry and to remove wrinkles from the laundry at home and in a laundry shop. The laundry treating apparatus is a concept including a washing machine that washes the laundry, a dryer that dries the laundry, a washer / dryer that has both a washing function and a drying function, a laundry manager that refreshes the laundry, and a steamer that removes the wrinkles from the laundry.

[0003] Recently, a laundry treating apparatus corresponding to the laundry manager that allows the laundry to be kept pleasant and clean without having to soak the laundry in water and wash the laundry with detergent has appeared.

[0004] A laundry treating apparatus that performs a refreshing cycle of deodorizing the laundry, drying the laundry, and removing the wrinkles from the laundry by supplying one of high-temperature air and steam to the laundry has appeared.

[0005] The laundry treating apparatus that may perform the refreshing cycle may be equipped to oscillate the laundry while supplying hot air or steam to the laundry, to remove fine dust or foreign substances attached to the laundry. See Korean Patent No. 10-1285890.

[0006] FIG. 1 shows a structure of oscillating laundry in an existing laundry treating apparatus.

[0007] A moving hanger M of the existing laundry treating apparatus includes a support bar 2 disposed in an accommodating space where the laundry is hung, a hanger 3 that extends downward from the support bar 2 such that the laundry may be hung thereon, and a driver 5 that may oscillate the support bar 2.

[0008] The driver 5 may include a motor 51 fixed on the support bar 2 to rotate a rotation shaft 53, and may include an eccentric shaft 55 coupled to the rotation shaft 53 to rotate along a trajectory greater than a rotational diameter of the rotation shaft 53.

[0009] The support bar 2 may have a reciprocation inducer 4 installed at a center to accommodate the eccentric shaft therein and receive power. The eccentric shaft 55 may move along the rotation of the rotation shaft 53 while coupled to the reciprocation inducer 4 and reciprocate the reciprocation inducer 4 in a left and right direction.

[0010] The eccentric shaft 55 may rotate by being coupled to a distal end of a connecting shaft 52 coupled to a distal end of the rotation shaft 53.

[0011] FIG. 2 shows a structure in which a support bar moves in a left and right direction.

[0012] The reciprocation inducer 4 may include a slit 41 defined in a thickness direction of the support bar 2 and accommodating the eccentric shaft 55 therein.

[0013] FIG. 2 shows a structure in which a support bar moves in a left and right direction.

[0014] The reciprocation inducer 4 may include a slit 41 defined in a thickness direction of the support bar 2 and accommodating the eccentric shaft 55 therein.

[0015] Referring to (a) in FIG. 2, the eccentric shaft 55 may be inserted into the slit 41 and rotate along an arc trajectory with a radius of a distance R from the rotation shaft 53.

[0016] The support bar 2 may be fixed so as to be able to move only in the left and right direction in the laundry treating apparatus and not to move forward or rearward.

[0017] Referring to (b) in FIG. 2, when the eccentric shaft 55 rotates 90 degrees to the right, the slit 41 may move by R to the right together with the eccentric shaft 55 as the eccentric shaft 55 moves by R to the right. As a result, the support bar 2 moves to the right.

[0018] In such manner, when the eccentric shaft 55 rotates 180 degrees to the left, the slit 41 will move to the left, and the support bar 2 will also move to the left.

[0019] When the rotation shaft 53 rotates once, the support bar 2 may reciprocate in the left and right direction once, and when the rotation shaft 53 rotates continuously, the support bar 2 may reciprocate in the left and right direction several times.

[0020] As a result, the laundry hung on the hanger 3 extended from the support bar 2 may be oscillated in the left and right direction, so that the foreign substances or the dust may be removed.

[0021] However, because the support bar 2 reciprocates in the left and right direction, such existing laundry treating apparatus has a problem that the entire laundry treating apparatus vibrates strongly because of a rapid inertial force applied whenever the support bar 2 changes a movement direction thereof.

[0022] In particular, the more or heavier the laundry hung on the hanger 3, the greater the vibration, so that stability of the laundry treating apparatus is not able to be guaranteed.

[0023] In addition, the existing laundry treating apparatus has a problem that the greater the vibration, the louder the noise generated, the noise is emitted whenever the laundry treating apparatus is operated, and a use of the laundry treating apparatus is restricted at night.

[0024] FIG. 3 shows a state in which a driver output of an existing laundry treating apparatus is lost.

[0025] In addition, the existing laundry treating apparatus has a problem in that even when the driver 5 is able to provide sufficient output, the vibration generated by the reciprocating motion of the support bar 2 exceeds a reference value, so that a maximum output of the driver 5 is not able to be utilized.

[0026] In addition, there is a problem that the moving hanger in the left-right reciprocating motion scheme, like the existing laundry treating apparatus, is not able to fully receive a rotational power of a driving force of the driver 5.

[0027] Specifically, the slit 41 of the support bar 2 of the moving hanger is able to transmit power of the eccentric shaft 55 of rotating left or right to the laundry, but is not able to transmit power of the eccentric shaft 55 rotating rearward or forward to the laundry at all and causes the power to be lost.

[0028] Specifically, when the eccentric shaft 55 is disposed at locations I and III, the slit 41 may directly receive power of moving right and left.

[0029] However, when moving from the location I to a location II and when moving from the location III to a location IV, the power transmitted by the eccentric shaft 55 to move the slit 41 in the left and right direction is drastically reduced.

[0030] This is because the force of moving the slit 41 by the eccentric shaft 55 corresponds only to a cosine value of a rotation direction of the eccentric shaft 55, and therefore, when the eccentric shaft 55 is at 90 degrees and 270 degrees with respect to a center of rotation, the power transmitted from the eccentric shaft 55 to the slit 41 corresponds to 0.

[0031] In other words, the driver 5 continuously transmits the power to the eccentric shaft 55, but the eccentric shaft 55 is only able to transmit a portion of the power to the slit 41, and is not able to transmit an entirety of the power at a certain point.

[0032] As a result, a significant portion of the power of the driver 5 is lost without being transmitted to the laundry in the existing laundry treating apparatus. Therefore, the existing laundry treating apparatus has a problem that sufficient oscillating force is not transmitted to the laundry even though the driver 3 has sufficient output to oscillate the laundry, or that the driver 3s has to be operated with excessive output to transmit the sufficient oscillating force to the laundry.

[0033] As a result, the existing laundry treating apparatus has a fundamental problem that a performance of removing the foreign substances or the dust attached to the laundry is not excellent because the sufficient oscillating force is not transmitted to the laundry from the driver 3.

[0034] In addition, the existing laundry treating apparatus has a problem that the rotational power generated from the driver 3 is not able to be directly transmitted to the support bar 2 because the support bar 2 is disposed in a width direction and the hanger 3 is also fixed to the support bar 2.

[0035] To solve such problem, a laundry treating apparatus that may shake the hanger 3 on which the laundry is hung in a reciprocating rotational motion rather than in a linear reciprocating motion has appeared (See Chinese Patent Application Publication No. 111759148).

[0036] FIG. 4 shows a rotation structure of a hanger in an existing known technology.

[0037] The hanger 3 is rotatably mounted on the support bar 2, and a link 5 that is seated on the hanger 3 and is able to reciprocate in the left and right direction is disposed.

[0038] The reciprocation inducer 4 may be coupled to an outer circumferential surface of the hanger 3 via a fastening member 6.

[0039] A portion of the fastening member 6 coupled to the hanger 3 may be disposed to be spaced apart from a center of rotation of the hanger 3.

[0040] The reciprocation inducer 4 may be equipped as a bar-shaped link. When the reciprocation inducer 4 reciprocates in the left and right direction in a width direction, the fastening member 6 may reciprocate the reciprocation inducer 4.

[0041] As a result, the hanger 3 may perform the reciprocating rotational motion in the left and right direction, and the laundry hung on the above hanger 3 may also perform the reciprocating rotational motion.

[0042] However, in the prior art, when the link 5 performs the reciprocating rotational motion, the reciprocation inducer 4 should move forward and rearward to some extent based on a rotational trajectory of the hanger 3. As a result, the left-right reciprocating motion of the reciprocation inducer 4 is not able to be a perfect left-right reciprocating motion.

[0043] In one example, when the hanger 3 includes a plurality of hangers arranged to be spaced apart from each other and one reciprocation inducer 4 reciprocates by the driver 3, it may seem that the plurality of hangers 3 are able to perform the reciprocating rotational motion.

[0044] However, for the plurality of hangers 3 to perform the reciprocating rotational motion, the reciprocation inducer 4 coupled with the plurality of hangers 3 should move forward or rearward to correspond to a rotational trajectory of each of the plurality of hangers 3. However, because one end of the reciprocation inducer 4 is fixed to a distal end 51 of the driver 3, the reciprocation inducer 4 is not able to entirely move in a front and rear direction equally to the rotational trajectories of the plurality of hangers 3.

[0045] That is, the reciprocation inducer 4 moves forward or rearward at a certain angle centered on the one end coupled with the driver 3. In other words, the reciprocation inducer 4 has a larger amplitude at the other end, which is farther away from the driver 3, than at the one end.

[0046] Therefore, when the plurality of hangers 3 are arranged in parallel with each other along the width direction of the support bar 2, it is theoretically impossible to rotate all of the plurality of hangers 3 with the reciprocation inducer 4.

[0047] Therefore, the reciprocation inducer 4 is not able to rotate the plurality of hangers 5 simultaneously or at the same time.

[0048] As a result, the prior art has a fundamental problem that, when there are the plurality of hangers 3, the plurality of hangers 3 are not able to perform the reciprocating rotational motion simultaneously or at the same time.SUMMARYTechnical Problem

In the present document, identical or similar components are assigned identical or similar reference numerals even in different embodiments, and descriptions thereof are replaced with the first description. A singular expression used herein includes a plural expression unless the context clearly indicates otherwise. In addition, when describing the embodiments disclosed herein, when it is determined that a detailed description of a related known technology may obscure the gist of the embodiments disclosed herein, the detailed description thereof will be omitted. In addition, it should be noted that the attached drawings are only intended to facilitate easy understanding of the embodiments disclosed herein, and the technical ideas disclosed herein should not be construed as being limited by the attached drawings.

[0168] FIG. 5 shows an outer appearance of a laundry treating apparatus 1 of the present disclosure.

[0169] Referring to (a) in FIG. 5, the laundry treating apparatus of the present disclosure may include a cabinet 10 forming the outer appearance thereof, and a door 11 pivotably coupled to the cabinet 10.

[0170] Referring to (b) in FIG. 5, an inner casing 20 having an accommodating space 21 for accommodating laundry may be disposed inside the cabinet 10. The inner casing 20 may have an opening in a front surface thereof through which the laundry enters and exits, and the opening may be shielded by the door 11.

[0171] The inner casing 20 may be made of a plastic resin-based material, and may be made of a reinforced plastic resin-based material that does not deform even when exposed to air at a temperature higher than a room temperature or heated air (hereinafter, hot air), steam, or moisture.

[0172] The inner casing 20 may have a height greater than a width. Accordingly, the laundry may be accommodated in the accommodating space 21 without being folded or crumpled.

[0173] The laundry treating apparatus 1 of the present disclosure may include a clothes hanger 900 that may hang the laundry in the accommodating space 21 of the inner casing 20.

[0174] The clothes hanger 900 may be disposed on a top surface of the inner casing 20 and may be seated on a hanger part 700 for hanging the laundry. The clothes hanger 900 may be detachable from the hanger part 700.

[0179] The machine room 30 may be disposed to be separated or partitioned from the inner casing 20, but may be in communication with the inner casing 20.

[0180] The machine room 30 may be disposed under the inner casing 20. Accordingly, when hot air and steam having low specific gravities are supplied to the inner casing 20, the hot air and the steam may be naturally supplied to the laundry.

[0181] The machine room 30 may include a circulation duct that circulates air inside the inner casing 20, and a plurality of heat exchangers disposed on the circulation duct to cool and condense the air and heat the air.

[0182] The machine room 30 may be equipped with a heat pump system including a compressor that is connected to the plurality of heat exchangers and is able to compress a refrigerant that cools or heats the air.

[0183] In one example, the machine room 30 may also be equipped with a steam supply that may supply steam into the inner casing 20.

[0184] The steam supply may heat water to generate the steam. Accordingly, the laundry accommodated inside the inner casing may be exposed to hot air and steam, so that deodorization, sterilization, and wrinkle removal may be performed.

[0185] In a front portion of the machine room 30, a water tank 31 that supplies water that generates the steam, and a drain tank 32 that collects condensed water in the circulation duct may be included.

[0186] The water tank 31 and the drain tank 32 may be detachably installed in the front portion of the machine room 30. Accordingly, even when the laundry treating apparatus of the present disclosure is not disposed near a water source or a drain hole, a user may detach and carry the water tank 31 and the drain tank 32 whenever necessary.

[0187] The water tank 31 and the drain tank 32 may be arranged in parallel with each other along a width direction of the machine room 30.

[0188] In addition, the machine room 30 may further include a drawer 33 that accommodates therein items or the like necessary for managing the laundry. The drawer 33 may be extendable from the machine room 30, and may have a space for accommodating the items such as an iron therein.

[0189] A seating stand 60 on which a separate shelf may be seated may be disposed inside the inner casing 20. The seating stands 60 may protrude at the same vertical level on both side surfaces of the inner casing 20.

[0190] The seating stand 60 may include a light emitter that irradiates light into the inner casing 20, and the light emitter may irradiate light toward the inner side surface of the inner casing 20 to prevent glare.

[0191] In one example, the laundry treating apparatus of the present disclosure may further include a moving hanger 100 that shakes the clothes hanger 900 to remove foreign substances and dust from the laundry hung on the clothes hanger 900.

[0192] The moving hanger 100 may operate when at least one of hot air and steam is supplied to the laundry, thereby inducing the foreign substances attached to the laundry to be removed by hot air or steam.

[0193] The moving hanger 100 may reciprocate and oscillate the clothes hanger 900.

[0194] FIG. 6 shows an upper structure of an inner casing.

[0195] The moving hanger 100 of the laundry treating apparatus of the present disclosure may include a power transmitter 400 disposed in an upper portion of the inner casing 10 to shake the clothes hanger 900.

[0196] The hanger part 700 on which the clothes hanger 900 may be seated or mounted may be disposed at a lower portion of the power transmitter 40.

[0197] Accordingly, when the power transmitter 40 moves, the hanger part 700 moves, and the clothes hanger 900 mounted on the hanger part 700 shakes, so that an effect of the laundry being shaken may be produced.

[0198] The power transmitter 400 may include a plurality of power transmitters, and the hanger part 700 coupled to the power transmitter 400 may also include a plurality of hangers. As a result, a large amount of laundry corresponding to the number of power transmitters 400 may be hung inside the inner casing 20 and refreshed.

[0199] The moving hanger 100 may further include a driver 200 that provides power to move the power transmitter 400.

[0200] When the driver 200 may be exposed into the inner casing 20 as long as it is able to transmit the power to the power transmitter 400. However, because the driver 200 operates by receiving electric energy, it is preferable that exposure to steam or hot air is blocked.

[0201] Accordingly, the driver 200 may be disposed between a top surface of the inner casing 20 and the cabinet 10 so as to be blocked from being exposed to the accommodating space 21.

[0202] The power transmitter 400 may receive the power from the driver 200 through the inner casing 20 and transmit the power to the hanger part 700.

[0203] The power transmitter 400 may extend through the top surface of the inner casing 20 and extend into the accommodating space 21. A lower end of the power transmitter 400 may be exposed to the accommodating space 21, and an upper end of the power transmitter 400 may be exposed to a portion above the inner casing 20.

[0204] The inner casing 200 or a support part 800 may further include a sealing member that may seal an area through which the power transmitter 400 extends. The sealing member may include a support bearing or the like, which is coupled to a hole in the inner casing 200 and the support part 800 that allows the power transmitter 400 to extend therethrough and rotatably supports the power transmitter 400.

[0205] As a result, air and steam supplied into the inner casing 200 may be blocked from leaking to a space above the top surface of the inner casing 200 or above the support member 800.

[0206] As a result, the driver 200 that is seated on the support part 800 may be stably operated without problems such as leakage, short circuit, or overheating.

[0207] The power transmitter 400 may be formed in a rod shape, a tube shape, or a plate shape, whose length is greater than a thickness.

[0208] In one example, the top surface of the inner casing 20 may support loads of the power transmitter 400 and the driver 200. The power transmitter 400 may move with the laundry hung thereon, and the load of the driver 200 may also be relatively great. Therefore, to stably install the moving hanger 100 on the top surface of the inner casing 20, the laundry treating apparatus 1 of the present disclosure may further include the support part 800.

[0209] The support part 800 may be disposed on the inner casing 20, but may be supported by being coupled to the cabinet 1. The support part 800 may be made of a metal material that is durable and difficult to deform.

[0210] The power transmitter 400 and the driver 200 may be seated on the support part 800 and disposed on the inner casing 20. The power transmitter 400 may extend through the support part 800 into the accommodating space 21.

[0211] In one example, the driver 200 includes a motor that rotates a rotation shaft. The driver 200 may move the power transmitter 400 with power that rotates the rotation shaft.

[0212] However, it may be difficult to shake the power transmitter 400 with a sufficient displacement by simply rotating the rotation shaft in place.

[0213] Therefore, the moving hanger 100 may further include a displacement generator 300 that is coupled to the rotation shaft rotated by the motor and generates the sufficient displacement to allow the power transmitter 400 to move.

[0214] The displacement generator 300 may be connected or coupled to the driver 200.

[0215] For example, the displacement generator 300 may transmit the power of the driver 200 to the power transmitter 400.

[0216] The displacement generator 300 may include an eccentric shaft that rotates along a trajectory greater than a diameter of the rotation shaft. The eccentric shaft may be directly coupled to the rotation shaft of the driver 200, but may be eccentrically coupled to or extended from a power shaft 240 that rotates by the rotation shaft.

[0217] The displacement generator 300 may be equipped as any component as long as it is able to generate a displacement that causes the power transmitter 400 to reciprocate within a certain range. A detailed structure thereof will be described later.

[0218] When the driver 200 operates, the power generated from the rotation shaft may generate the displacement of the displacement generator 300, and the power transmitter 400 may move based on the displacement of the displacement generator 300.

[0219] The displacement generator 300 may directly move the power transmitter 400, but may move the power transmitter 400 via an additional component.

[0220] The moving hanger 100 of the present disclosure may reciprocate the power transmitter 400.

[0221] In addition, the moving hanger 100 of the present disclosure may rotate the power transmitter 400. Specifically, the moving hanger 100 may allow the power transmitter 400 to perform the reciprocating rotational motion within a certain angular range, rather than reciprocate the power transmitter 400 in a straight line.

[0222] The power transmitter 400 may perform the reciprocating rotational motion clockwise or counterclockwise at a fixed location, and the laundry hung on the power transmitter 400 may also perform the reciprocating rotational motion clockwise or counterclockwise. The power transmitter 400 may rotate by the moving hanger 100, but may not move while varying the location thereof to the left or right.

[0223] Even when the laundry rotates by the power transmitter 400 inside the inner casing 20, a movement of a center of gravity thereof may be restricted inside the inner casing 20. Therefore, even when the moving hanger 100 operates, vibration occurring inside the inner casing 20 may be drastically reduced, and noise generation may also be minimized.

[0224] To this end, the moving hanger 100 may further include a reciprocating rotating part 500 that converts continuous rotational energy generated from the driver 200 or the displacement generator 300 into the reciprocating rotational motion of the power transmitter 400.

[0225] The reciprocating rotating part 500 may connect the displacement generator 300 with the power transmitter 400. The reciprocating rotating part 500 may connect the displacement generator 300 with the power transmitter 400 at a location above the inner casing 20. The reciprocating rotating part 500 may be prevented from being exposed to the accommodating space 21, thereby preventing the laundry from being damaged by the reciprocating rotating part 500.

[0226] In one example, the moving hanger 100 may allow only one of the plurality of power transmitters 400 to perform the reciprocating rotational motion.

[0227] However, when only one power transmitter 400 rotates, laundry hung on the rotating power transmitter may collide with laundry hung on another power transmitter 400 and be damaged. In addition, there is a concern that an impact may be transmitted to the moving hanger 100, thereby damaging the moving hanger 100.

[0228] Therefore, it is preferable that the moving hanger 100 rotates all of the plurality of power transmitters 400.

[0229] The moving hanger 100 may rotate the plurality of power transmitters 400 integrally. The plurality of moving hangers 400 may be rotated by the same angle simultaneously. Thus, the laundry treating apparatus of the present disclosure may prevent the power transmitters 400 from colliding with each other.

[0230] It may be advantageous in rotating all of the power transmitters 400 that the power generated by the driver 200 is directly transmitted to the plurality of power transmitters 400.

[0231] However, when the driver 200 is equipped to directly transmit the power to each of the power transmitters 400, a structure of connecting the driver 200 with all of the power transmitters 400 may become complicated.

[0232] In addition, when the driver 200 includes a plurality of drivers, or when there are a plurality of components that connect the driver 200 with all of the power transmitters 400, excessive load may be applied to the inner casing 20 or the support part 800. In addition, inconvenience of having to control the plurality of drivers 200 may also occur.

[0233] In addition, when the displacement generator 300 and the reciprocating rotating part 500 are connected to transmit the power transmitted from the single driver 200 to each of the power transmitters 400, an arrangement and structures of the displacement generator 300 and the reciprocating rotating part 500 may become complicated, which may lower reliability.

[0234] Therefore, the moving hanger 100 may be equipped such that the single driver 200 generates the power to rotate the plurality of power transmitters 400.

[0235] In addition, the moving hanger 100 may be equipped such that the power generated by the driver 200 may be preferentially transmitted to some of the power transmitters 400 or some of the reciprocating rotating parts 500, and then the power may be secondarily transmitted to the remaining power transmitters 400 or the remaining reciprocating rotating parts 500.

[0236] For example, the reciprocating rotating part 500 may receive the power transmitted from the driver 200 or the displacement generator 300 and transmit the power to some of the power transmitters 400. That is, the moving hanger 100 may be equipped such that the power generated by the driver 200 is intensively transmitted to the single reciprocating rotating part 500, thereby simply designing a power transmission structure and minimizing a power loss.

[0237] The moving hanger 100 of the present disclosure may transmit the power transmitted from the driver 200 to the single reciprocating rotating part 500, thereby rotating a specific power transmitter 400 connected to the reciprocating rotating part 500.

[0238] In addition, the moving hanger 100 may further include a connector 600 that transmits the power transmitted to the specific power transmitter 400 to another power transmitter 400.

[0239] For example, the connector 600 may connect the plurality of power transmitters 400 to each other. Accordingly, when one power transmitter 400 rotates, the connector 600 may rotate all of the plurality of power transmitters 400.

[0240] FIG. 7 shows an operating scheme of a moving hanger of the present disclosure.

[0241] Referring to (a) in FIG. 7, the power transmitter 400 may rotate to the right by the reciprocating rotating part 500 when the driver 200 operates. In this regard, all of the power transmitters 400 connected to the connector 600 may also rotate to the right.

[0242] Referring to (b) inFIG. 7, the power transmitter 400 may rotate to the left by the reciprocating rotating part 500 when the driver 200 further operates. In this regard, all of the power transmitters 400 connected to the connector 600 may also rotate to the left.

[0243] As such process is repeated, the power transmitter 400 may rotate in the left and right direction.

[0244] In this regard, the power transmitter 400 may rotate in the left and right direction while being fixed at a fixed location. The power transmitter 400 may be fixed to the support part 800 such that there is no change in location in a front and rear direction and the left and right direction when rotating.

[0245] The power transmitter 400 may be fixed such that the location thereof does not move based on a vertical direction, the front and rear direction, and a width direction.

[0246] However, the power transmitter 400 may rotate in the left and right direction using the vertical direction or a height direction in which the power transmitter extends as a rotation shaft. As a result, when the driver 200 operates, the hanger part 700 may perform the reciprocating rotational motion in the left and right direction around the power transmitter 400, and there may be no location movement.

[0247] Referring to (c) in FIG. 7, the clothes hanger 900 may include a ring 910 hung on the hanger part 700 and a seating portion 900 coupled to the ring 910. A surface-modified portion 950 that prevents the laundry from slipping may be disposed on a surface of the seating portion 950.

[0248] The seating portion 950 may be bilaterally symmetric around the ring 910. The clothes hanger 900 may be hung on the hanger part 700 such that the seating portion 950 is disposed in the front and rear direction.

[0249] When the power transmitter 400 rotates to the left, in the clothes hanger 900, a left side of the seating portion 950 based on the ring 910 may rotate to the left, and a right side of the seating portion 950 may rotate to the right. In this regard, an angle I at which the left side of the seating portion 950 rotates may be equal to an angle (theta) at which the right side of the seating portion 950 rotates, and a distance at which the left side of the seating portion 950 moves may be equal to a distance at which the right side of the seating portion 950 moves.

[0250] As a result, a weight and a force moving to the left and a weight and a force moving to the right may be equal to each other based on the clothes hanger 900, and thus may be offset from each other.

[0251] Similarly, even when the power transmitter 400 rotates to the right, as a result, the weight and the force moving to the left and the weight and the force moving to the right may be equal to each other based on the clothes hanger 900, and thus may be offset from each other.

[0252] As a result, even when the power transmitter 400 rotates, the forces applied to the clothes hanger 900 may be offset from each other, and as a result, a vibration force or an oscillating force, or an inertial force generated from the clothes hanger 900 itself may be minimized. As a result, inertial forces or the like generated from the plurality of power transmitters 400 may be minimized, and thus vibration or noise generated from the entire moving hanger 100 may be minimized, and vibration or noise generated from the entire laundry treating apparatus 1 may be drastically reduced.

[0253] As a result, even when the driver 200 rotates at the maximum output, the vibration generated from the moving hanger 100 or the entire laundry treating apparatus 1 may not be significantly generated.

[0254] Instead, because a surface of each laundry hung on the clothes hanger 900 rotates in the left and right direction to shake off dust, a dust shaking power may be greatly secured.

[0255] As described above, the power transmitter 400 may extend through the inner casing 20 to receive the power and perform the reciprocating rotational motion clockwise and counterclockwise. As a result, the power transmitter 400 may perform the reciprocating rotational motion in the left and right direction while the location thereof is fixed on the inner casing 20. The power transmitter 400 is fixed such that the location thereof does not change in the vertical direction and the left and right direction. In addition, not only an upper portion, but also a lower portion of the power transmitter 400 is fixed such that the location thereof does not change in the vertical direction and the left and right direction.

[0256] That is, the power transmitter 400 may perform a partial reciprocating rotational motion by a certain angle without completing a full revolution while a center of rotation thereof is fixed.

[0257] As a result, no matter how fast the power transmitter 400 rotates, the clothes hanger 900 is fixed in location and one end thereof rotates or moves to one side and the other end thereof rotates or moves to the other side, so that forces and vibrations transmitted to the power transmitter 400 may be offset from each other.

[0258] Therefore, the vibration and the noise generated by the power transmitter 400, the hanger part 700, and the clothes hanger 900 inside the inner casing 20 may be minimized.

[0259] As a result, the laundry treating apparatus of the present disclosure may rotate the driver 200 at a higher rpm to reciprocate the power transmitter 400 at a higher frequency. As a result, the laundry treating apparatus of the present disclosure may shake the laundry more strongly.

[0260] For example, the existing moving hanger M in the left-right reciprocating motion scheme and the moving hanger 100 of the present disclosure may be equipped with the driver 200 that exhibits the same output.

[0261] The existing moving hanger M has a limitation that the driver 200 is not able to operate at an rpm equal to or higher than a certain rpm. When the driver 200 operates at the rpm equal to or higher than the certain rpm, vibration generated from the laundry may exceed a limit value, and the vibration may damage the existing moving hanger M or generate excessive vibration or noise in the laundry treating apparatus.

[0262] However, in the moving hanger 100 of the present disclosure, the power transmitter 400 performs the reciprocating rotational motion clockwise or counterclockwise in place. Therefore, as described above, no matter how fast the clothes hanger 900 rotates, the vibrations or the inertial forces generated from the clothes hanger 900 and the laundry may be offset from each other when transmitted to the power transmitter 400.

[0263] As a result, even when the moving hanger 100 of the present disclosure increases the rpm of the driver 200 to the certain rpm or higher, the moving hanger 100 may not be damaged, and the generation of the vibration or the noise exceeding the limit value in the laundry treating apparatus may be blocked.

[0264] Therefore, the laundry treating apparatus of the present disclosure may operate the driver 200 faster than the laundry treating apparatus using the existing moving hanger, and may operate the power transmitter 400 at the higher frequency to shake the laundry more strongly.

[0265] Therefore, the laundry treating apparatus of the present disclosure may remove the foreign substances on the laundry more reliably via the moving hanger 100, and may remove the wrinkles from the laundry more effectively.

[0266] In addition, the laundry treating apparatus of the present disclosure may oscillate the laundry faster and more expose the laundry to supplied steam.

[0267] In addition, the laundry treating apparatus of the present disclosure may freely adjust the rpm of the driver 200 to adjust the operating frequency or an operating cycle of the power transmitter 400 based on a course.

[0268] FIG. 8 shows an embodiment of a moving hanger 100 of the present disclosure.

[0269] The moving hanger 100 of the present disclosure may transmit the power of the driver 200 to only one of the plurality of power transmitters 400, and transmit the power transmitted to the specific power transmitter 400 to the remaining power transmitters 400 via the connector 600.

[0270] The displacement generator 300 or the reciprocating rotating part 500 may intensively transmit the power generated by the single driver 200 to the single power transmitter 400. The connector 600 may transmit the power transmitted to the specific power transmitter 400 to all of the power transmitters 400.

[0271] The connector 600 may be equipped as a rigid body such that a length thereof does not vary, and may connect all of the power transmitters 400 to each other.

[0272] Accordingly, all of the power transmitters 400 may simultaneously rotate in the same direction and by the same angle when the connector 600 moves. As a result, the moving hanger 100 of the present disclosure may allow the plurality of power transmitters 400 to perform the reciprocating rotational motion simultaneously or at the same time by the same angle with the single driver 200.

[0273] The moving hanger 100 may include the driver 200 that is fixed on the inner casing 20 and provides the power for moving the power transmitter, the plurality of reciprocating rotating parts 500 that are respectively coupled to the plurality of power transmitters 400 and receive the power from the driver 200 to rotate such that a rotation direction thereof repeatedly changes, and the connector 600 that connects the plurality of reciprocating rotating parts to each other.

[0274] The connector 600 may include a link bar that connects the plurality of reciprocating rotating parts 500 to each other and rotates the plurality of reciprocating rotating parts 500 integrally.

[0275] The connector 600 may be equipped as a single unit.

[0276] The connector 600 may connect all of the power transmitters 400 to each other.

[0277] However, when the connector 600 connects the reciprocating rotating parts 500 to each other, the connector 600 may be installed upward of the support part 800, and thus, may be prevented from being exposed into the inner casing 20.

[0278] The connector 600 may be coupled to one of a front portion and a rear portion of the reciprocating rotating part 500, and at least one of the displacement generator 300 and the driver 200 may be disposed on the other of the front portion and the rear portion of the reciprocating rotating part 500. Therefore, the connector 600 may be prevented from interfering with the driver 200.

[0279] The connector 600 may reciprocate in the width direction of the inner casing 20 and rotate the plurality of reciprocating rotating parts 500.

[0280] The driver 200 may include a motor 210 that rotates a rotation shaft 210, the power shaft 240 that rotates together when the rotation shaft 210 rotates, and a transmitter 230 that connects the power shaft 240 with the rotation shaft 210 to transmit rotational power of the rotation shaft 210 to the power shaft 240.

[0281] The motor 210 may be fixed on the inner casing 20 and rotate the rotation shaft 220. However, the rotation shaft 220 is equipped to rotate too fast compared to an appropriate cycle for the motor 210 to allow the power transmitter 400 to perform the reciprocating rotational motion. When the rpm of the rotation shaft is lowered considering the above, there is a concern that the output of the motor 210 may not be transmitted to the power transmitter 400.

[0282] To solve such problem, the transmitter 230 may transmit the output of the rotation shaft 220 as it is to the power transmitter 400, but lower the rpm of the rotation shaft 220.

[0283] The transmitter 230 may rotate by being connected to the rotation shaft 220, but may rotate with a diameter larger than that of the rotation shaft 220. Accordingly, the transmitter 230 may transmit a torque of the rotation shaft 220 while rotating at an rpm lower than the rpm of the rotation shaft 220.

[0284] The power shaft 240 may rotate by the transmitter 230, may be formed separately from the rotation shaft 230, and may be a component that directly transmits the power to the power transmitter 400.

[0285] The reciprocating rotating part 500 may be coupled to the power transmitter 400 and may be rotatable together with the power transmitter 400.

[0286] The reciprocating rotating part 500 may include a reciprocating lever 510 coupled to the upper portion of the power transmitter 400 to rotate the power transmitter 400.

[0287] The reciprocating lever 510 may be formed in a rib or rod shape with a center of rotation coupled to a support shaft 410.

[0288] The reciprocating lever 510 may be coupled to an upper end of each of the plurality of power transmitters 400, and some of the reciprocating levers 510 may be connected to the transmitter 230 and receive the power from the motor 210.

[0289] The reciprocating lever 510 may perform the reciprocating rotational motion by a certain angle when the transmitter 230 is rotated by the motor 210. The power transmitter 400 may be coupled to the center of rotation of the reciprocating lever 510 and rotate together with the reciprocating lever 510.

[0290] The plurality of reciprocating levers 510 may be connected to each other via the connector 600.

[0291] The connector 600 may connect respective one ends of the plurality of reciprocating levers 510 to each other.

[0292] Accordingly, even when one of the plurality of reciprocating levers 510 rotates, the connector 600 may move and the plurality of reciprocating levers 510 may rotate simultaneously and at the same time.

[0293] The power transmitter 400 and the reciprocating lever 510 may be supported by the support part 800. In addition, the motor 210 and the transmitter 230 may also be supported by the support part 800.

[0294] FIG. 9 shows a moving hanger 100 of the present disclosure separated from an inner casing 20.

[0295] The power transmitter 400 may extend from above to below the inner casing, and the hanger part 700 may be coupled to the lower portion of the power transmitter 400.

[0296] Each reciprocating rotating part 500 may be coupled to each power transmitter 400, and may be easily connected to the driver 200 by being coupled to the upper portion of the power transmitter 400.

[0297] The power transmitter 400 and the reciprocating rotating part 500 respectively include the plurality of power transmitters and the plurality of reciprocating rotating parts arranged at a predetermined distance apart from each other along the width direction of the inner casing.

[0298] The connector 600 connects the plurality of power transmitters 400 or the plurality of reciprocating rotating parts 500 to each other. Thus, the connector 600 may simultaneously rotate the plurality of power transmitters 400 or the plurality of reciprocating rotating parts 500.

[0299] The power transmitter 400 may include the support shaft 410 that extends through an upper portion of the inner casing 20 and is coupled to the reciprocating lever 510.

[0300] The support shaft 410 may extend through the support part 800 and be exposed to a space above the support part 800 or above the inner casing 20.

[0301] The power transmitter 400 may include an auxiliary support part 420 coupled to the support shaft 410 and exposed to the accommodating space. The auxiliary support part 420 may be formed in a rod shape and the hanger part 700 may be coupled and fixed to a lower portion of the auxiliary support part 420.

[0302] The auxiliary support part 420 may be fixed to the support shaft 410 and rotate together with the support shaft 410. Accordingly, when the support shaft 410 is rotated by the reciprocating lever 510, the auxiliary support part 420 coupled to the support shaft 410 may also rotate, thereby allowing the hanger part 700 to rotate in the left and right direction.

[0303] The reciprocating levers 510 may include a main lever 511 that receives the power directly from the driver 200 and performs the reciprocating rotational motion, and an auxiliary lever 512 that receives the power from the main lever 511 via the connector 600.

[0304] The main lever 511 may be equipped as a single unit and may directly receive the power from the driver 200.

[0305] In the driver 200, the motor 210 may include a vertical motor 211 coupled to the support part 800, and a vertical rotation shaft 221 that rotates by the vertical motor 211.

[0306] The transmitter 230 may include a power pulley 231 that is coupled to the vertical rotation shaft 221 and rotates together with the vertical rotation shaft 221, a transmission pulley 232 that is coupled to the power shaft 240 and rotates the power shaft 240, and a belt 233 that connects portions of outer circumferential surfaces of the power pulley 231 and the transmission pulley 232 to each other.

[0307] The transmitter 230 may further include a pulley support 224 that rotatably supports the power shaft 240 and the transmission pulley 232. The pulley support 224 may support the transmission pulley 232 so as to be disposed in parallel with the power pulley 231, and may be seated on the support part 800.

[0308] The power shaft 240 may transmit the power transmitted from the rotation shaft 220 to one of two ends of the main lever 511.

[0309] The displacement generator 300 may be coupled to the power shaft 240 to receive the power. In addition, the displacement generator 300 may be connected to the main lever 511 to allow the main lever 511 to perform the reciprocating rotational motion around the support shaft 410.

[0310] For example, the displacement generator 300 may include an eccentric shaft that is eccentrically coupled to the power shaft 240 and rotates at a certain radius around a center of rotation of the power shaft 240.

[0311] The displacement generator 300 may be connected to a distal end of the main lever 511. The displacement generator 300 may allow the distal end of the main lever 511 to perform the reciprocating rotational motion around the support shaft 410 while being rotated by the power shaft 240.

[0312] The connector 600 may include a link bar 610 connecting one of the two ends of the main lever 511 that is not connected to the power shaft 240 or the displacement generator 300 with one end of the auxiliary lever 512.

[0313] The auxiliary levers 512 may be rotatably coupled to the remaining support shafts 410 that are not coupled to the main lever 511, and may extend in one direction from respective portions coupled to the support shafts 410 and be connected to the link bar 610.

[0314] The link bar 610 may be formed in a shape of a straight frame connecting one end of the main lever 511 with respective one ends of the auxiliary levers 512. In this regard, the one end of the main lever 511 and the respective one ends of the auxiliary levers 512 may be arranged parallel to each other based on the link bar 610 or the width direction.

[0315] The link bar 610 may be equipped as a single unit and may rotate the main lever 511 and the auxiliary levers 512 simultaneously and at the same time around their respective support shafts 410.

[0316] The inner casing 20 may include a through-hole 23 in which a portion of the support part 800 is seated to expose the power transmitter 400 to the accommodating space 22.

[0317] The through-hole 23 may be defined in the top surface 22 of the inner casing, and the through-hole 23 may be defined along the direction in which the power transmitters 400 are arranged.

[0318] For example, the power transmitters 400 may be arranged to be spaced apart from each other along the width direction of the inner casing, and the through-hole 23 may be defined along the width direction of the inner casing.

[0319] The laundry treating apparatus 1 of the present disclosure may further include a support frame 12 that is disposed outside the inner casing and supports the cabinet 1.

[0320] The support frame 12 may be disposed at a location corresponding to each corner of the cabinet 1 or each corner of the inner casing 20 and may be made of a metal material that maintains the outer appearance of the laundry treating apparatus. The support part 800 may have both ends seated and supported on the support frame 12, thereby preventing unnecessary impact or load from being transmitted to the top surface 22 of the inner casing.

[0321] FIG. 10 is an exploded perspective view of a moving hanger 100 of the present disclosure.

[0322] The power transmitter 400 may include the support shaft 410 that passes through the top surface of the inner casing 20 and is coupled to the reciprocating lever 510, the auxiliary support part 420 that is coupled to the support shaft 410 and is exposed to the accommodating space 21, and the hanger part 700 that is coupled to the auxiliary support part 420 and hangs the clothes hanger 900 or the laundry thereon.

[0323] The support shaft 410 may be formed in a cylindrical shape whose length is greater than a diameter, and thus, may be easily rotated by the reciprocating lever 510.

[0324] The support shaft 410 may have a diameter much smaller than that of the auxiliary support part 420, thereby extending through the inner casing or the support part 800 with a smaller area size. Therefore, a possibility of hot air or steam supplied to the accommodating space leaking upwardly of the inner casing 20 may be further reduced.

[0325] The auxiliary support part 420 may have a larger cross-sectional area than the support shaft 410 and may have a greater length than the support shaft 410. As a result, the auxiliary support part 420 may secure a rigidity and an area size to support and rotate the hanger part 700 and the clothes hanger 900.

[0326] The support part 800 may include a support plate 810 through which the support shaft 410 passes and on which the driver 200 may be supported. The support plate 810 may be equipped as a metal plate so that rigidity and durability may be guaranteed, and may extend in the direction in which the plurality of power transmitters 400 are arranged.

[0327] The support part 800 may include an extending body 812 extending upward from both ends of the support plate 810 to define a space in which the driver 200 and the reciprocating rotating part 500 are seated between the inner casing 20 and an upper portion of the cabinet 10, and a seating body 813 extending from the extending body 821 so as to be seated on the support frame 12.

[0328] The support part 800 may include a shaft coupling portion 820 through which the support shaft 410 may extend.

[0329] The shaft coupling portion 820 may include a plurality of shaft coupling portions so as to be arranged at locations corresponding to the locations where the power transmitters 400 are arranged, and may be arranged to be spaced apart from each other along a length direction of the support plate 810.

[0330] In one example, the support part 800 may further include an auxiliary plate 880 coupled to a lower portion of the support plate 810. The auxiliary plate 880 may be made of a resin-based material and may partially accommodate an outer circumferential surface of the power transmitter 400 therein.

[0331] The auxiliary plate 880 may include a plurality of accommodating holes 882 that may be defined below the support plate 810 and rotatably accommodate the respective power transmitters 400 therein, a plurality of extension steps 883 extending from the respective accommodating holes 882 with a greater width, and a fixed plate 881 that may extend from the extension steps 883 to face the support plate 810 and may be coupled and fixed to the support plate 810.

[0332] The accommodating hole 882 may be defined at an upper end of the support shaft 410 or the auxiliary support part 420 to prevent hot air or air from being discharged to the shaft coupling portion 820. The extension step 883 may serve to disperse a load or an impact transmitted to the auxiliary plate 880, and may serve to prevent collision or interference between the accommodating hole 882 and the clothes hanger 900.

[0333] The support part 800 may further include a seating plate 820 seated on the support plate 810.

[0334] The seating plate 820 may serve to support a bearing seated on the shaft coupling portion 820 and, at the same time, may serve to prevent the reciprocating lever 510 and the connector 600 from colliding with or rubbing against the support plate 810.

[0335] The seating plate 820 may include a seating board 861 seated on the support plate 810, and a seating hole 862 that passes through the seating board 861 and is defined in an area corresponding to the shaft coupling portion 820.

[0336] The reciprocating levers 510 may include the main lever 511 that directly receives the power from the driver 200, and the auxiliary levers 512 that receive the power from the main lever 511 via the connector 600.

[0337] The main lever 511 and the auxiliary levers 512 may be coupled to the respective support shafts 410 and rotate around the support shafts 410.

[0338] The link bar 610 may include a link body 611 that may be seated on the main lever 511 and the auxiliary levers 512 and may connect them to each other, and connecting hooks 612 that may protrude from the link body 611 and may be rotatably disposed on the main lever 511 and the auxiliary levers 512.

[0339] The reciprocating lever 510 may include link bearings 513 that are respectively coupled to the one end of the main lever 511 and the respective one ends of the auxiliary levers 512 and rotatably supports the respective connecting hooks 612.

[0340] When the link bar 610 rotates in the left and right direction, the main lever 511 or the auxiliary lever 512 may perform the reciprocating rotational motion in the left and right direction.

[0341] The reciprocating rotating part 500 may further include a support bearing 530 that may rotatably support the support shaft 410 or the reciprocating lever 510.

[0342] The support bearing 530 may rotatably accommodate the support shaft 410 therein and may be seated on the shaft coupling portion 620.

[0343] The reciprocating lever 510 may be disposed on an upper surface of the support bearing 530.

[0344] The support bearing 530 may be composed of a plurality of components stacked or may be equipped as a ball bearing or an oilless bearing.

[0345] The seating plate 860 may support the support bearing 530 and may block hot air or moisture from being exposed from an outer circumferential surface of the support bearing 530.

[0346] In addition, the auxiliary plate 880 may also be disposed under the support bearing 530 and block hot air or moisture from being exposed from the outer circumferential surface of the support bearing 530.

[0347] FIG. 11 shows an operating scheme of a moving hanger 100 of the present disclosure.

[0348] Referring to (a) in FIG. 11, the main lever 511 may include a main body 5111 coupled to the support shaft 410 and coupled to the link bar 610.

[0349] The main body 5111 may include a main center hole 5115 that may be coupled to the support shaft 410 and rotate the support shaft 410, and may extend from the main center hole 5115 to both sides.

[0350] The main body 5111 may include a main receiving hole 5112 that receives the power from the driver 200 at one end, and may include a main transmitting hole 5113 in which the link bar 610 is seated and coupled at the other end.

[0351] The main body 5111 may further include a stepped portion 5114 that extends from the center hole to the main receiving hole 5112, but forms a step. In the main body 5111, because of the stepped portion 5114, one end of the main body 5111 or the main transmitting hole 5113 may be positioned downward of the main center hole 5115.

[0352] Therefore, a length of the power shaft 240 or the eccentric shaft 310 positioned on the main center hole 5115 extending from the transmitter 230 may be secured.

[0353] In one example, the auxiliary lever 512 may include an auxiliary body 5121 having an auxiliary center hole 5125 coupled to the support shaft 410 and an auxiliary transmitting hole 5123 extending to one side from the auxiliary center hole 5125 and coupled to the link bar 610.

[0354] The auxiliary body 5121 may have a length smaller than that of the main body 5111.

[0355] A distance from the main center hole 5115 to the main transmitting hole 5113 may be set to be equal to a distance from the auxiliary center hole 5125 to the auxiliary transmitting hole 5123.

[0356] The link bar 610 may be seated on the auxiliary transmitting hole 5123 and the main transmitting hole 5113 to connect the auxiliary lever 512 with the main lever 511.

[0357] Referring to (b) in FIG. 11, the driver 200 may be equipped such that the power shaft 240 is inserted into the main receiving hole 5112. As a result, the power shaft 240 may be directly rotated to rotate the main receiving hole 5112 in the left and right direction.

[0358] In other words, the power shaft 240 may not generate enough displacement to rotate the main receiving hole 5112 in the left and right direction based on the main center hole 5115 by only rotating.

[0359] To this end, the displacement generator 300 may be coupled to the power shaft 240 to generate a displacement greater than a rotation radius of the power shaft 240.

[0360] The displacement generator 300 may convert the stationary rotational motion of the power shaft 240 into a reciprocating displacement motion within a certain range. The displacement motion may be transmitted to the reciprocating rotating part 500, so that the power transmitter 400 may perform the reciprocating rotational motion.

[0361] As described above, the displacement generator 300 may include an eccentric shaft 310 that is coupled to further extend from the power shaft 240 and rotates while drawing a trajectory along a certain radius.

[0362] The eccentric shaft 310 may have a diameter smaller than that of the power shaft 240, and may coupled to or extended from the power shaft 240 while being spaced a predetermined distance apart from a center of rotation of the power shaft 240.

[0363] Therefore, the eccentric shaft 310 may rotate in a circle with a radius of the distance separated from the power shaft 240 when the power shaft 240 rotates.

[0364] The diameter of the eccentric shaft 310 may be set smaller than a diameter or a width of the main receiving hole 5112. Thus, the eccentric shaft 310 may be inserted into and supported by the main receiving hole 5112.

[0365] However, the predetermined radius of rotation of the eccentric shaft 310 may be set greater than the width or the diameter of the main receiving hole 5112. As a result, when the eccentric shaft 310 rotates, the main receiving hole 5112 may be pushed by the eccentric shaft 310 and may move in the left and right direction based on the main center hole 5115.

[0366] As a result, when the eccentric shaft 310 rotates in a specific direction x, the main receiving hole 5112 of the main body 511 may also perform the reciprocating rotational motion along a certain direction y. As a result, the center hole 5115 of the main body may also rotate in the same direction as the main receiving hole 5112, and the main transmitting hole 5113 may perform the reciprocating rotational motion in a direction z opposite to the certain direction.

[0367] When the eccentric shaft 310 rotates, the support shaft 410 may perform the reciprocating rotational motion together with the main center hole 5115, so that the power transmitter 400 may perform the reciprocating rotational motion. Further, the main transmitting hole 5113 may also perform the reciprocating rotational motion to reciprocate the link bar 610, so that the auxiliary lever 521 may also perform the reciprocating rotational motion around the auxiliary center hole 5125 and the support shaft 410. The power transmitter 400 coupled to the auxiliary lever 521 may also perform the reciprocating rotational motion.

[0368] The power transmitter 400 may have a screw thread along a circumference of the upper portion of the support shaft 410.

[0369] The main transmitting hole 5113 and the auxiliary center hole 5125 may be directly coupled and fixed to the support shaft 410 using the screw thread or the like.

[0370] However, the power transmitter 400 may further include a transmitter coupling portion 415 that is coupled to the screw thread of the support shaft 410 so as to extend through the main transmitting hole 5113 and the auxiliary center hole 5125 and then fix the support shaft 410 to the main transmitting hole 5113 and the auxiliary center hole 5125.

[0371] Therefore, the support shaft 410 and the reciprocating lever 510 may be coupled to each other by the transmitter coupling portion 415, so that the support shaft 410 and the reciprocating lever 510 may rotate simultaneously.

[0372] FIG. 12 shows an operating process of a moving hanger 100 of the present disclosure.

[0373] Referring to (a) in FIG. 12, in the main lever 511, the main receiving hole 5112 may rotate to the left with respect to the main center hole 5115 by the rotation of the eccentric shaft 310 (No. 1).

[0374] When the main receiving hole 5112 rotates to the left, the main center hole 5115 may also rotate counterclockwise (No. 2). In this process, the power transmitter 400 coupled to the main center hole 5115 may rotate counterclockwise.

[0375] The main receiving hole 5113 rotates counterclockwise around the main center hole 5115. In this regard, the link bar 610 may move to the right as the main receiving hole 5113 moves (No. 3).

[0376] When the link bar 610 moves to the right, the auxiliary receiving hole 5123 in the auxiliary lever 512 rotates counterclockwise with respect to the auxiliary center hole 5125.

[0377] Because the link bar 610 is connected to the plurality of auxiliary levers 512, all the auxiliary levers 512 rotate counterclockwise (No. 4).

[0378] When the auxiliary lever 512 rotates counterclockwise, the power transmitter 400 coupled to the auxiliary center hole 5125 also rotates counterclockwise (No. 5).

[0379] Referring to (b) in FIG. 12, the main receiving hole 5112 in the main lever 511 may rotate to the right with respect to the main center hole 5115 by the rotation of the eccentric shaft 310 (No. 1).

[0380] When the main receiving hole 5112 rotates to the right, the main center hole 5115 may also rotate clockwise (No. 2). In this process, the power transmitter 400 coupled to the main center hole 5115 may rotate clockwise.

[0381] The main receiving hole 5113 rotates clockwise around the main center hole 5115. In this regard, the link bar 610 may move to the left as the main receiving hole 5113 moves (No. 3).

[0382] When the link bar 610 moves to the left, the auxiliary receiving hole 5123 in the auxiliary lever 512 rotates clockwise with respect to the auxiliary center hole 5125. Because the link bar 610 is connected to the plurality of auxiliary levers 512, all the auxiliary levers 512 rotate clockwise (No. 4).

[0383] When the auxiliary lever 512 rotates clockwise, the power transmitter 400 coupled to the auxiliary center hole 5125 also rotates clockwise (No. 5).

[0384] When this process is repeated, the main lever 511 may receive the power from the driver 200 and perform the reciprocating rotational motion clockwise and counterclockwise, thereby allowing the power transmitter 400 coupled to the main lever 511 to perform the reciprocating rotational motion and reciprocating the link bar 610 in the left and right direction.

[0385] The link bar 610 may allow the auxiliary lever 512 to perform the reciprocating rotational motion while reciprocating in the left and right direction, and may allow the power transmitter 400 coupled to the auxiliary lever 512 to perform the reciprocating rotational motion.

[0386] The link bar 610 is formed as the rigid body, and the auxiliary lever 512 and the main lever 511 are coupled to the link bar 610 at locations spaced apart from the respective support shafts 410 by the same length.

[0387] Therefore, because of the link bar 610, the auxiliary lever 512 and the main lever 511 may perform the reciprocating rotational motion by the same angle, and as a result, all the power transmitters 400 may rotate at the same angle simultaneously and at the same time, and angles of the reciprocating rotational motion thereof may also be the same.

[0388] The main lever 511 may be disposed between the auxiliary levers 512. In addition, the auxiliary levers 512 may be arranged symmetrically with respect to the main lever 511. As such, a load may be evenly applied to both sides of the link bar 610 connected to the main lever 511.

[0389] However, when the power of the main lever 511 is able to be transmitted to the auxiliary lever 512, the main lever 511 and the auxiliary levers 512 may be arranged in any arrangement or order.

[0390] FIG. 13 shows a power transmission structure of a moving hanger 100 of the present disclosure.

[0391] As described above, the power generated from the driver 200 may not be directly transmitted to all the reciprocating levers 510, but may be transmitted to the main lever 511, and the remaining auxiliary levers 512 may instead receive the power via the link bar 610.

[0392] The driver 200 may include the vertical motor 211 seated on the support part 800, and the rotation shaft 221 that rotates in the vertical motor 211.

[0393] The driver 200 may include the transmitter 230 that may transmit the torque as it is while lowering the rpm transmitted from the rotation shaft 221, and the transmitter 230 may include the power pulley 231 coupled to the rotation shaft 221, the transmission pulley 232 disposed adjacent to the main lever 511 on the power pulley 231, and the belt 233 connecting the power pulley with the transmission pulley.

[0394] The power shaft 240 that is coupled to the transmission pulley 232 and rotates is included.

[0395] The power shaft 240 may transmit the power to allow the main lever 511 to perform the reciprocating rotational motion, and the main lever 511 may allow the auxiliary lever 512 to perform the reciprocating rotational motion via the link bar 610.

[0396] The power transmitters 400 respectively coupled to the main lever 511 and the auxiliary levers 512 and supported by the support part 800 may perform the reciprocating rotational motion in place to allow the hangers 900 to perform the reciprocating rotational motion.

[0397] FIG. 14 shows a coupled structure of the driver and the displacement generator.

[0398] The transmission pulley 232 may be formed in a disk shape, and the power shaft 240 may be firmly coupled inside the transmission pulley 232.

[0399] The power shaft 240 may include a shaft body 241 coupled to the transmission pulley 232 and extending toward the main lever 511 and a shaft boss 242 coupled to an upper end of the shaft body 241 and fixed to the transmission pulley 232.

[0400] In one example, the transmitter 230 may include a pulley support 234 that is seated on the support part 800 to rotatably support the shaft body 241 and also support a load of the transmission pulley 232.

[0401] The pulley support 234 may be made of a metal material.

[0402] The displacement generator 300 may include the eccentric shaft 310 that may be inserted into the main receiving hole 5111 and rotate at a free end of the power shaft 240.

[0403] The eccentric shaft 310 may rotate along a trajectory having a diameter larger than the diameter of the power shaft 240.

[0404] The main body 511 may be fixedly coupled to the support shaft 410 that passes through the inner casing 20 or the support part 800. The main body 511 may have a center of rotation coupled to the support shaft 410 and one end accommodating the eccentric shaft 310 therein.

[0405] The power transmitter 400 may include the support shaft 410 and the auxiliary support part 420 that passes from the support shaft 410, and the auxiliary support part 420 may be coupled while accommodating a portion of the support shaft 410 therein.

[0406] The support part 800 may seat the support bearing 530, which rotatably supports the support shaft 410, on a top surface thereof, and the main body 511 may be coupled to an upper portion of the support bearing 530.

[0407] As a result, loads of the hanger part 700 and the clothes hanger 900 may be transmitted to the power transmitter 400, and the power transmitter 400 may support the loads of the hanger part 700 and the clothes hanger 900.

[0408] In the power transmitter 400, the support shaft 410 supports a load of the auxiliary support part 420. The support bearing 530 and the main lever 511 support a load of the support shaft 410. In one example, the support bearing 530 and the auxiliary lever 512 also support a load of the support shaft 410 coupled thereto.

[0409] Therefore, loads of the support bearing 530 and the reciprocating lever 510 are supported on the support part 800 via the support bearing 530. As a result, the support part 800 may support a load of the entire moving hanger 100 and be fixed to the cabinet 10.

[0410] FIG. 15 shows a structure of a main lever.

[0411] The main lever 511 may include the main body 5111 that extends to both sides from the main center hole 5115 coupled to the support shaft 410.

[0412] The main body 5111 has the main receiving hole 5112 in which the eccentric shaft 310 or the power shaft 240 is rotatably accommodated at one end thereof, and the main transmitting hole 5113 into which a hook coupling portion of the link bar 610 is coupled at the other end thereof.

[0413] Distances at which the main receiving hole 5112 and the main transmitting hole 5113 are spaced apart from the main center hole 5115 may be set to be equal to each other, but may be set to be different from each other.

[0414] The main body 5111 may transmit a greater torque to the main center hole 5115 and the main transmitting hole 5113 as a distance between the main receiving hole 5112 and the main center hole 5115 is set to be greater.

[0415] FIG. 16 is an exploded perspective view of a driver of a moving hanger 100 of the present disclosure.

[0416] The vertical motor 211 may include a motor fastening portion 214 coupled to the support part 800, and a sensor 213 that senses an operating state of the vertical motor 211 or an rpm state of the vertical motor and transmits the state to a controller.

[0417] The vertical rotation shaft 221 may be rotatably disposed at a center of the vertical motor 211.

[0418] The power pulley 231 may be coupled to one end of the vertical motor 211. The power pulley 231 may have a groove defined along an outer circumferential surface thereof, corresponding to a thickness or a width of the power belt 233.

[0419] The transmission pulley 232 may include a transmission body 2321 formed in a shape of a disk or a wheel with a diameter larger than that of the power pulley 231. A groove 2322 in which the belt 2333 may be seated may be defined in an outer circumferential surface of the transmission body 2321.

[0420] A plurality of reinforcing beads 2324 for maintaining rigidity may be disposed on both surfaces of the transmission body 2321. A through-coupling portion 2323 through which the power shaft 240 extends and is coupled may be defined at a center of the transmission body 2321. The reinforcing beads 2324 may extend radially from the through-coupling portion 2323.

[0421] The pulley support 234 may include a seating body 2341 that is seated on the support part 800, and a support body 2341 that ascends upwards in a stepped manner from a center of the seating body 2341 to support the load of the power shaft 240.

[0422] A pulley bolt 235 coupled to the support part 800 may extend through the seating body 2341 and be coupled to the seating body 2341.

[0423] A bearing support 2342 that supports the outer circumferential surface of the power shaft 240 may extend on the support body 2341, and a pulley bearing 2344 that rotatably supports the power shaft 240 may be seated inside the bearing support 2342.

[0424] The pulley support 234 may further include a cut groove 2345 defined by cutting one of the support body 2341, the seating body 2341, and the bearing support 2442 to guide the main lever 511 to be coupled to the eccentric shaft 310.

[0425] The power shaft 240 may include the shaft body 241 that is coupled to the transmitter 230 and rotates, and a first bearing 243 that is disposed around a lower portion of the shaft body 241 and is rotatably coupled to the pulley bearing 2344 or the bearing support 2342.

[0426] The power shaft 240 may further include a second bearing 244 coupled to the shaft body 241 by being spaced downwardly apart from the first bearing 243.

[0427] Between the first bearing 243 and the second bearing 244, a separation groove 245 defined along a circumference of the shaft body 241 may be defined.

[0428] Therefore, the first bearing 243 and the second bearing 244 may be rotatably coupled to the bearing support 2442 to support the shaft body 241 so as not to bend.

[0429] A ring-to-be-inserted that may be inserted into the separation groove 245 may be formed on an inner circumferential surface of the bearing support 2442. Because of the ring-to-be-inserted, an installation vertical level of the shaft body 241 may be maintained, and at the same time, a load of the transmission pulley 232 may also be transmitted to the pulley support 234.

[0430] The eccentric shaft 310 may include an eccentric shaft body 311 that extends from one side of the power shaft 240 and is accommodated in the main receiving hole 5112.

[0431] In this regard, an eccentric bearing 312 that is coupled to an outer circumferential surface of the eccentric shaft body 311 to expand a diameter of the eccentric shaft 310, extend an angle of the reciprocating rotational motion of the main lever 511, and reinforce rigidity of the eccentric shaft body 311 may be included.

[0432] The eccentric bearing 312 may be made of a material different from that of the eccentric shaft body 311.

[0433] The eccentric shaft 310 may further include a fixing clip 313 that fixes the eccentric bearing 312 and the eccentric shaft body 311.

[0434] The eccentric bearing 312 may rotate based on the eccentric shaft body 311, and may rotate by being in contact with the inner circumferential surface of the main receiving hole 5112.

[0435] Therefore, even when the eccentric shaft 310 rotates at a high rpm, a frictional force between the eccentric shaft 310 and the main receiving hole 5112 may be minimized.

[0436] FIG. 17 shows a connection structure of a driver and a reciprocable portion of the moving hanger 100 of the present disclosure.

[0437] The power transmitter 400 may be coupled to the reciprocating rotating part 500 and perform the reciprocating rotational motion.

[0438] At least one of the power shaft 240 and the eccentric shaft 310 may be disposed parallel to the power transmitter 400.

[0439] The support body 420 may perform the reciprocating rotational motion in the left and right direction with respect to the support shaft 410.

[0440] The power transmitter 400 may be merely equipped to perform the reciprocating rotational motion clockwise and counterclockwise with respect to the support shaft 410, and the location thereof may not vary in a radial direction or the like.

[0441] The support shaft 410 may allow the support body 420 to perform the reciprocating rotational motion while the vertical location thereof is completely fixed via the support bearing 530.

[0442] The support body 420 may rotate while changing a rotation direction thereof with respect to the support shaft 410.

[0443] In one example, the power transmitter 400 also supports the loads of the hanger part 700, the clothes hanger 900, and the laundry in the inner casing 200 or transfers the loads to the support part 800.

[0444] The support frame 810 may support the load of the hanger by supporting the load of the power transmitter 400.

[0445] The support part 800 may further place the auxiliary plate 880 under the support frame 810.

[0446] The auxiliary plate 880 may include an auxiliary body 881 disposed under the support frame 810, and an auxiliary through-hole 882 that extends through the auxiliary body 881 and allows the support shaft 410 or the like to extend therethrough.

[0447] The support bearing 530 is coupled to the shaft coupling portion 820 of the support 820 to rotatably support the support shaft 410 and seal the outer circumferential surface of the support shaft 410. In addition, the support bearing 530 also seals an inner circumferential surface of the shaft coupling portion 820.

[0448] The auxiliary through-hole 882 may further extend upward of the auxiliary body 881 along a height direction of the support shaft 410. In other words, the auxiliary through-hole 882 may not be defined as a simple hole, but may be formed in a cylindrical shape that extends upward to have a certain height and accommodates at least a portion of the support shaft 410 therein.

[0449] In addition, the auxiliary plate 880 may include a blocking wall 885 that extends away from the auxiliary through-hole 882 such that the auxiliary through-hole 882 may be accommodated inside the auxiliary body 881.

[0450] The blocking wall 885 may also be formed in a cylindrical shape, and may have a diameter that allows the auxiliary through-hole 882 and the support shaft 410 to be disposed inside the blocking wall.

[0451] The blocking wall 885 may have a height so as to overlap at least a portion of the support bearing 530, and may have a diameter so as to accommodate at least a portion of the support bearing 530 therein.

[0452] The blocking wall 885 may be disposed at a predetermined distance from an outer circumferential surface of the shaft coupling portion 820 or an outer circumferential surface of the support bearing 530.

[0453] As a result, the auxiliary plate 880 may increase a flow resistance between the outer circumferential surface of the support shaft 410 and the auxiliary through-hole 882, and may increase a flow resistance between the shaft coupling portion 820 and the auxiliary body 881.

[0454] As a result, steam and hot air supplied into the inner casing 200 may be blocked to the maximum extent from flowing through the auxiliary through-hole 882 and the shaft coupling portion 820 toward the support bearing 530.

[0455] A detailed structure of the auxiliary plate 880 will be described later.

[0456] FIG. 18 shows a coupling structure of components.

[0457] (a) in FIG. 18 shows a coupling structure of the connector 600 and the reciprocating lever 510. The reciprocating lever 510 may further include a link bearing 513 coupled to the main transmitting hole 5113 or the auxiliary transmitting hole 5123 to rotatably support the connecting hook 612.

[0458] The link bearing 513 may be made of a material different from that of the reciprocating lever 510, may be made of a self-lubricating material, or may be equipped as a general bearing.

[0459] A distal end of the connecting hook 612 may be formed in a wedge shape or an arrowhead shape that enables easy insertion into the link bearing 513, the main transmitting hole 5113, or the auxiliary transmitting hole 5123, while preventing easy removal.

[0460] The connecting hook 612 may have a bifurcated distal end that diverges further outward than a fixed end, and an outer circumferential surface of the distal end may protrude outward to prevent removal of the reciprocating lever 510.

[0461] (b) in FIG. 18 shows an arrangement structure of a support and a shaft coupling portion.

[0462] The support part 800 may include a seating groove 822 defined as the support plate 810 is recessed into the outer circumferential surface of the shaft coupling portion 820.

[0463] A diameter of the seating groove 822 may correspond to the outer circumferential surface of the support bearing 530.

[0464] Accordingly, the support bearing 530 may be supported by being seated in the seat groove 822.

[0465] A passage hole 821 through which the support shaft 410 passes may be defined in an inner circumferential surface of the seat groove 822.

[0466] That is, the support frame 800 may include the passage hole 821 through which at least a portion of the power transmitter passes, and the seating groove 822 that supports a bearing that is seated in the passage hole and rotatably supports the power transmitter.

[0467] The reciprocating rotating part 500 may be coupled to the power transmitter on the support frame 810 to support the power transmitter or transmit the load of the power transmitter to the support frame 810.

[0468] (c) in FIG. 18 shows a coupling structure of a power shaft and a reciprocating lever.

[0469] The eccentric shaft body 311 may extend from the power shaft 240, and the fixing clip 313 that prevents removal of the eccentric bearing may be coupled to a free end of the eccentric shaft body 311. The fixing clip 313 may be formed integrally with the eccentric shaft body 311.

[0470] The eccentric bearing 312 may be coupled to an outer circumferential surface of the eccentric shaft body 311.

[0471] The eccentric shaft 310 may further include a fixing cylinder 314 coupled to the outer circumferential surface of the eccentric shaft body 311 to fix the eccentric bearing 312.

[0472] Protrusions spaced apart from each other along the height direction may be disposed on an outer circumferential surface of the fixing cylinder 314 and may be in contact with the inner circumferential surface of the eccentric bearing 312. As a result, a coupling force between the eccentric bearing 312 and the eccentric shaft body 311 may be strengthened.

[0473] The eccentric bearing 312 may be formed as a sponge or the like having elasticity and resilience to absorb impact.

[0474] FIG. 19 shows a structure supporting a displacement generator in a moving hanger 100 of the present disclosure.

[0475] Referring to (a) in FIG. 19, the pulley support 234 defines the cut groove 2345 in one side of a seating body 2343 into which the reciprocating lever 510 is inserted. The seating body 2343 may be formed as a metal plate that may be seated on the support plate 810.

[0476] The support body 2341 may extend upward from an inner circumferential surface of the seating body 2343, and the bearing support 2342 may be disposed on an inner circumferential surface of the support body 2341.

[0477] The support body 2341 may also have one side open to define the cut groove 2345.

[0478] The cut groove 2345 may have a width that allows the main lever 510 to reciprocate at a sufficient rotation angle.

[0479] The seating body 2343 includes a plurality of coupling holes 2347 into which the respective pulley bolts coupled to the support plate 810 are coupled, spaced apart from each other by a certain distance along a circumference of the seating body 2343.

[0480] Referring to (b) in FIG. 19, the transmission pulley 232 is coupled to the belt 233 on the pulley support 234 and generates considerable vibration while rotating.

[0481] In addition, when the belt 233 is coupled while the pulley support 234 accommodates the power shaft 240 therein and the transmission pulley 232 is seated, there is a risk that the pulley support 234 may move even slightly toward the rotation shaft 220 because of a tension of the belt 233.

[0482] In addition, the power shaft 240 coupled to the transmission pulley 232 and supported by the pulley support 234 receives a force of being pulled toward the rotation shaft 220 or a force of vibrating in various directions because of the tension provided by the belt 233.

[0483] In particular, the pulley support 234, which is subjected to vibrations generated when the power transmitter 400 performs the reciprocating rotational motion by the power shaft 240, is subjected to strong vibrations.

[0484] In addition, when an installation position of the pulley support 234 varies, a location of the cut groove 2435 changes, so that there is a risk that the pulley support 234 interferes with the reciprocating motion of the main lever 510.

[0485] Therefore, to strengthen a fixing force for fixing the pulley support 234 to the support part 800 and prevent the pulley support 234 from sliding even at a certain distance, the pulley support 234 may further include a support protrusion 2346 inserted into the support plate 810.

[0486] The support protrusion 2346 may protrude from a lower portion of the seating body 2343 and may be disposed to face the main lever 511. As a result, not only may be the location where the cut groove 2435 is defined naturally guided, but also the pulley support 234 may be firmly fixed to the support plate 810.

[0487] In addition, even when the tension is applied to the belt 233, the installation location of the pulley support 234 may be fixed without arbitrarily varying by the support projection 2346.

[0488] The support plate 810 may include a protrusion accommodating hole 814 through which the support protrusion 2346 may extend and be coupled. In one example, the support plate 810 may further include a coupling hole 815 into which the pulley bolt is coupled.

[0489] FIG. 20 shows a structure of a power transmitter in a moving hanger 100 of the present disclosure.

[0490] Referring to (a) in FIG. 20, the power transmitter 400 may include the support shaft 410 that receives the power from the driver 200 by extending through the support plate 810, and the auxiliary support part 420 that is coupled to the support shaft 410 and rotates together with the support shaft 410.

[0491] The hanger 900 may be coupled and fixed to the auxiliary support part 420.

[0492] The support shaft 410 may be coupled and fixed to an upper portion of the auxiliary support part 420, and the support shaft 410 may be coupled at an exact center of a top surface of the auxiliary support part 420.

[0493] Referring to (b) in FIG. 20, the support shaft 410 may include a convey body 411 that is coupled to the reciprocating rotating part 500 and receives the power of the driver 200, and an extension part 412 that extends downward from the convey body 411 and is seated on the auxiliary support part 420.

[0494] The convey body 411 may have a screw thread along an outer circumferential surface thereof, so that the convey body 411 may be directly coupled to the reciprocating rotating part 500, or may be coupled to the transmitter coupling portion 415 and fixed to the reciprocating rotating part 500.

[0495] The extension part 412 may have a diameter larger than that of the convey body 411, and the diameter thereof may expand continuously or in a stepwise manner as it extends downward from the convey body 411. As a result, the extension part 412 may stably support the auxiliary support part 420 while ensuring durability.

[0496] The auxiliary support part 420 may include a shaft support 425 on which the extension part 412 is seated, and a coupling tube 424 that extends upward from the shaft support 425 and accommodates a portion of an outer circumferential surface of the extension part 412 therein.

[0497] The auxiliary support part 420 may include a plate body 421 that extends downward from the shaft support 425 and is coupled with the hanger 900.

[0498] The plate body 421 may have a length that is much greater than a cross-sectional area. A support projection 423 that protrudes to one side from a distal end of the plate body 421 to support the hanger part 700 may be disposed.

[0499] The plate body 421 may be formed in a rectangular parallelepiped shape.

[0500] The plate body 421 may include first surfaces on which stands 730, which will be described below, are disposed and which extend in the vertical direction to form both side surfaces of the plate body 421, and a second surface that has an area size smaller than that of the first surface and connects the first surfaces to each other.

[0501] The hanger part 700 may be formed in any shape as long as it is able to hang the ring 910 of the clothes hanger 900 thereon by being coupled to the plate body 421.

[0502] The hanger part 700 may include a hanger body 710 that includes a hanger groove 720 in which the plate body 421 is inserted in a direction of the second surface and is accommodated.

[0503] The stand 730 on which the ring 910 may be hung may protrude on at least one of both side surfaces of the hanger body 710.

[0504] The stand 730 may include a stand groove 740 in which the ring 910 is inserted and supported in an upper portion thereof, and may include a recessed portion 750 recessed to disperse the load in a side surface thereof.

[0505] The stand 730 may have a width corresponding to a width of the hanger body 710, and may be disposed at a lower side of the hanger body 710.

[0506] The hanger body 710 may support both surfaces of the plate body 421, so that even when the plate body 421 performs the reciprocating rotational motion based on the support shaft 410, a coupling force may be stably maintained.

[0507] The support projection 423 may support a bottom surface of the hanger body 710, so that the hanger body 710 may be prevented from being removed from the plate body 421.

[0508] FIG. 21 shows a detailed structure of a power transmitter in a moving hanger 100 of the present disclosure.

[0509] Referring to (a) in FIG. 21, the hanger body 710 and the plate body 421 may be coupled with each other via a fastening member.

[0510] Specifically, the plate body 421 may have an input hole 426 into which the fastening member may be inserted and a fastening hole 427 through which the fastening member passes and is coupled in the second surface.

[0511] The fastening hole 427 may be defined in an area corresponding to the hanger groove 720 in the hanger body 710, and the input hole 426 may be defined to face one surface of the hanger body 710 facing the hanger groove 720.

[0512] The fastening member may be coupled with the fastening hole 427 by being inserted into the input hole 426 through the hanger body 710. As a result, the hanger part 700 may be firmly coupled with the auxiliary support part 420 via the fastening member.

[0513] Referring to (b) in FIG. 21, the support shaft 410 may include the convey body 411 having a screw thread so as to be coupled to the transmitter coupling portion 415 through the inner casing 20, the support part 800, and the reciprocating lever 510, and the extension part 412 that extends from the convey body 411 and is coupled to the auxiliary support part 420.

[0514] The convey body 411 may be formed in a cylindrical shape, but may have the screw thread formed on the outer circumferential surface thereof.

[0515] The extension part 412 may include a coupling pillar 4121 that is disposed under the convey body 411 and coupled to the reciprocating lever 510. The coupling pillar 4121 may be an area that is coupled to an inner circumferential surface of the main center hole 5115 of the main lever and an inner circumferential surface of the auxiliary center hole 5125 of the auxiliary lever.

[0516] The coupling pillar 4121 may have a polygonal cross-section instead of a curved one, unlike the convey body 411. In addition, the main center hole 5115 and the auxiliary center hole 5125 may also be formed in a shape corresponding to the cross-sectional shape of the coupling pillar 4121.

[0517] For example, the cross-section of the coupling pillar 4121 may be formed in a square shape.

[0518] As a result, the main center hole 5115 and the auxiliary center hole 5125 may be prevented from rotating idly around the coupling pillar 4121. Accordingly, the rotational power of the driver 200 transmitted to the main lever 510 and the auxiliary levers 512 may be fully transmitted to the support shafts 410, and the power transmitter 400 may perform the reciprocating rotational motion to maximize a performance of removing dust from the laundry.

[0519] The extension part 412 may include a lubricated pillar 4122 that extends from a lower portion of the coupling pillar 4121 and is rotatably supported on the support bearing 530.

[0520] The lubricated pillar 4122, as an area that is positioned downward of the main lever 510 and the auxiliary lever 512 and an area that is rotatably supported on the inner circumferential surface of the support bearing 530, may be an area that at least partially faces the support plate 800 or an area that is positioned upward of the support plate 800.

[0521] Unlike the coupling pillar 4121, the lubricated pillar 4122 may have a circular cross-section. Accordingly, the lubricated pillar 4122 may be able to rotate completely in the support bearing 530, and thus may not interfere with the reciprocating rotational motion of the support shaft 410.

[0522] The lubricated pillar 4122 may have a greater cross-sectional area than the coupling pillar 4121, thereby performing the reciprocating rotational motion while more stably supporting a load added thereto.

[0523] The extension part 412 may further include a support pillar 4123 that extends downward from the lubricated pillar 4122 and is coupled to the auxiliary support part 420. The support pillar 4123 may have a greater cross-sectional area than the lubricated pillar 4122. Accordingly, the support pillar 4123 may not only stably support the auxiliary support part 420, but may also stably transmit the transmitted rotational power to the auxiliary support part 420.

[0524] As a result, the support shaft 410 may become thicker in a stepwise manner as it goes downward.

[0525] A lower end of the support pillar 4123 may be recessed and coupled to the auxiliary support part 420.

[0526] The support shaft 410 is a component that supports the entire loads of the power transmitter 400, the hanger part 700, and the clothes hanger 900 and allows the power transmitter 400, the hanger part 700, and the clothes hanger 900 to perform the reciprocating rotational motion. Therefore, the support shaft 410 may be made of a rigid metal material to maintain durability even when the great torque, inertial force, excessive load, vibration, and the like are added thereto.

[0527] However, the auxiliary support part 420 has a much greater volume and a greater length than the support shaft 410, so that when the auxiliary support part 420 is made of a metal material, a weight thereof may become unnecessarily great, which makes the reciprocating rotational motion difficult. Therefore, the auxiliary support part 420 may be made of a material lighter than the metal material, such as a resin-based material.

[0528] Because the support shaft 410 and the auxiliary support part 420 are made of the different materials, there is a risk that, when the support shaft 410 and the auxiliary support part 420 are simply coupled to each other, the auxiliary support part 420 may rotate idly when the support shaft 410 rotates.

[0529] To prevent such problem, the support shaft 410 may include a support board 4124 that may allow the lower end of support pillar 4123 to be accommodated in and coupled to the auxiliary support part 420, may have an area size greater than that of the support pillar 4123, and may be accommodated in and coupled to the auxiliary support part 420.

[0530] In addition, the support shaft 410 may be formed with a chamfered portion 414 that is formed linearly on a portion of a side surface thereof so as to prevent the support shaft 410 from rotating idly in the auxiliary support part 420.

[0531] The chamfered portion 414 may strengthen a coupling force between the outer circumferential surface of the support shaft 410 and the inner circumferential surface of the auxiliary support part 420 by forming a portion of the outer circumferential surface of the cross-section of the support shaft 410 linearly rather than curved.

[0532] For example, the chamfered portion 414 may be formed on at least one of the support pillar 4123 and the support plate 4124.

[0533] The chamfered portion 414 may include a first chamfered portion 4141 formed on one or two sides of an outer circumferential surface of the support pillar 4123, and a second chamfered portion 4142 formed on one or two sides of an outer circumferential surface of the support plate 4124.

[0534] In this regard, the first chamfered portion 4141 and the second chamfered portion 4142 may be arranged to be staggered relative to a rotation direction of the support shaft 410.

[0535] That is, the second chamfered portion 4142 may not be directly disposed under the first chamfered portion 4141, but a curved surface may be disposed under the first chamfered portion 4141, and the second chamfered portion 4142 may be disposed at a location that does not face the first chamfered portion 4141.

[0536] When the first chamfered portion 4141 is disposed to face forward, the second chamfered portion 4142 may be oriented laterally.

[0537] As a result, the coupling tube 424 that is coupled to the first chamfered portion 4141 while accommodating the same and the shaft support 425 that is coupled to the second chamfered portion 4142 while accommodating the same may receive the rotational power in different directions, thereby preventing the auxiliary support part420 from rotating idly on the support shaft 410, and preventing stress from being concentrated on a specific area of the auxiliary support part 420.

[0538] FIG. 22 shows a power transmission structure of a moving hanger 100 of the present disclosure.

[0539] Referring to (a) in FIG. 22, the moving hanger 100 of the present disclosure allows the reciprocating rotating part 500 to which the power transmitter 400 is coupled to perform the reciprocating rotational motion.

[0540] The moving hanger 100 of the present disclosure does not convert the rotational energy of the driver 200 into a linear reciprocating motion of the power transmitter 400, the hanger part 700, the clothes hanger 900, and the reciprocating rotating part 500.

[0541] In other words, the moving hanger 100 of the present disclosure converts the energy of the driver 200 rotating the rotation shaft 220 into a motion of rotating the power transmitter 400, the hanger part 700, the clothes hanger 900, and the reciprocating rotating part 500, without converting the same into the linear motion.

[0542] As a result, the moving hanger 100 of the present disclosure may transfer all of the power generated during 360-degree rotation of the rotation shaft 220 as energy for performing the reciprocating rotational motion of the power transmitter 400, the hanger part 700, and the clothes hanger 900. Accordingly, the moving hanger 100 of the present disclosure may use the power generated from the driver 200 to shake the laundry during an entire time period in which the driver 200 operates. Therefore, the moving hanger 100 of the present disclosure may transfer sufficient oscillating force to the laundry even when the driver 200 operates at the low output, thereby effectively removing dust from the laundry.

[0543] In addition, even when the driver 200 operates for a short period of time, because the power generated from the driver 200 is transferred to the laundry during the entire time period in which the driver 200 operates, a time period for operating the moving hanger 100 may be reduced, and a laundry management cycle itself may be shortened.

[0544] The reciprocating rotating part 500 may include the receiving hole 5112 that receives the power from the eccentric shaft 310 and rotates, the transmitting hole 5113 that is coupled to the connector 600 and rotates, and the center hole 5115 that is coupled to a center of rotation 410 of the power transmitter 400 and rotates the power transmitter, based on the reciprocating lever 510.

[0545] A width or a diameter of the receiving hole 5112 may be set to be greater than a diameter of the eccentric shaft 310. The receiving hole 5112 may be longer in a length direction of the reciprocating lever 510.

[0546] However, the diameter of the receiving hole 5112 may be set to be smaller than a radius of rotation R of the eccentric shaft 310.

[0547] The eccentric shaft 310 may be accommodated in the receiving hole 5112 and may pass through points I, II, III, and IV while rotating with a diameter larger than the width of the receiving hole 5112. When the eccentric shaft 310 is at the point II, the receiving hole 5112 is pushed to the right and moved to a right point 5112a, and when the eccentric shaft 310 is at the point IV, the receiving hole 5112 is pushed to the left and moved to a left point 5112b.

[0548] In such process, the transmitting hole 5113 moves to the left point 5113a and the right point 5113b.

[0549] In addition, when the eccentric shaft 310 is at the points I and III, the receiving hole 5112, the transmitting hole 5113, and the support shaft 410 are placed in correct locations.

[0550] As such, whenever the eccentric shaft 310 rotates once, the reciprocating lever 510 may perform the reciprocating rotational motion in the left and right direction once, the support shaft 410 may also perform the reciprocating rotational motion once, and another reciprocating lever 510 may also perform the reciprocating rotational motion once by the connector 600.

[0551] In addition, when the eccentric shaft 310 passes the point I, which is a 0-degree location, and the point III, which is a 180-degree location, based on a center of rotation of a rotation trajectory thereof, the power of the eccentric shaft 310 is completely transmitted to the support shaft 410 and transmitted to the transmitting hole 5113 as it is.

[0552] For example, when the eccentric shaft 310 rotates clockwise, a force F1 of moving to the right when the eccentric shaft 310 passes the point I is transmitted as it is to the support shaft 410 and the transmitting hole 5113 as the force F1 of moving to the left.

[0553] In addition, when the eccentric shaft 310 passes the point III, a force F3 of moving to the left is transmitted as it is to the support shaft 410 and the transmitting hole 5113 as the force F3 of moving to the right.

[0554] However, even when the eccentric shaft 310 passes the point II, which is a 90-degree location, and the point IV, which is a 270-degree location, based on the center of rotation of the rotation trajectory thereof, the power of the eccentric shaft 310 is still transmitted to the support shaft 410 and the transmitting hole 5113.

[0555] For example, when the eccentric shaft 310 moves clockwise, a force F2 of moving downward when the eccentric shaft 310 passes the point II is transmitted by being divided into a force Fa parallel to the direction in which the transmitting hole 5113 and the support shaft 410 rotate and a force Fb perpendicular to the direction in which the transmitting hole 5113 and the support shaft 410 rotate.

[0556] Therefore, the force F2 generated from the eccentric shaft 310 is still transmitted to the transmitting hole 5113 and the support shaft 410 as much as the force Fa parallel to the direction in which the transmitting hole 5113 and the support shaft 410 rotate.

[0557] In addition, when the eccentric shaft 310 corresponds to the point IV, the Fa will be reversed only in direction and transmitted to the transmitting hole 5113 and the support shaft 410.

[0558] As a result, the moving hanger 100 of the present disclosure may always transmit the power received from the driver 200 to the support shaft 410 and the transmitting hole 5113, regardless of the location of the eccentric shaft 310.

[0559] This is a significant difference from the existing laundry treating apparatus, which does not transmit any power to the power transmitter 400 and the clothes hanger 900, but dissipates the power when the eccentric shaft 310 rotates at the points II and IV.

[0560] Referring to (b) in FIG. 22, the receiving hole 5112 is defined to be spaced apart from the support shaft 410 or the center hole 5115 by a maximum of L2 and a minimum of L1.

[0561] In addition, the receiving hole 5112 is defined to be spaced apart from the transmitting hole 5113 by a distance greater than L2.

[0562] In one example, a torque T is required to rotate the support shaft 410, and the torque T is proportional to the force that generates the rotational power and a distance L from the support shaft 410, which is a point of action.

[0563] In this regard, the eccentric shaft 310 is positioned at a maximum of L2 and a minimum of L1 from the support shaft 410 while rotating once, and continuously generates the force F that rotates the support shaft 410.

[0564] In addition, the eccentric shaft 310 is always positioned to be spaced apart from the support shaft 410 by a distance greater than L1 throughout entire rotation thereof.

[0565] As a result, the support shaft 410 is always applied with the torque generated from the rotation of the eccentric shaft 310 without a point where the torque becomes 0. Therefore, whenever the eccentric shaft 310 rotates 360 degrees, the torque may always be applied to the support shaft 410, and the power transmitted to the eccentric shaft 310 may always act as the power to rotate the support shaft 410.

[0566] FIG. 23 shows a process in which the reciprocating rotating part performs a reciprocating rotational motion in detail.

[0567] As shown in (b) in FIG. 23, the eccentric shaft 310 may be disposed at a location I and be disposed at one end or a distal end of the main receiving hole 5112.

[0568] Thereafter, when the power shaft 240 rotates 90 degrees clockwise, because the eccentric shaft 310 is spaced apart from a center of rotation of the power shaft 240 by 1 / 2R, the eccentric shaft 310 may move to the right by 1 / 2R.

[0569] In addition, the main center hole 5112 also moves to the right, and the main body 5111 rotates the support shaft 410 clockwise. Accordingly, the power transmitter 400 coupled to the main lever 511 rotates clockwise, and the hanger part 700 coupled to the power transmitter 400 and the clothes hanger 900 hung on the hanger part 700 also rotate clockwise. Accordingly, the laundry also rotates clockwise.

[0570] In one example, the main transmitting hole 5113 moves to the left in an opposite direction to the main receiving hole 5112 centered on the support shaft 410. Accordingly, the connector 600 is moved to the left, and all of the auxiliary levers 512 coupled to the connector 600 are moved to the left, so that all of the power transmitters 400 coupled to the auxiliary levers 512 may be rotated clockwise.

[0571] Thereafter, the power shaft 310 is disposed at a location III when rotating 90 degrees, and is disposed at a location IV when rotating 180 degrees.

[0572] In such process, the main center hole 5112 moves to the left again and then moves further to the left, and the main lever 511 moves counterclockwise. As a result, the main lever 511 may be disposed in states in (b) and (a) in FIG. 22.

[0573] In such process, the power transmitter 400 coupled to the main lever 511 rotates clockwise, and the hanger part 700 coupled to the power transmitter 400 and the clothes hanger 900 hung on the hanger part 700 also rotate counterclockwise. Accordingly, the laundry also rotates counterclockwise.

[0574] In one example, the main transmitting hole 5113 moves to the right in an opposite direction to the main receiving hole 5112 centered on the support shaft 410. Accordingly, the connector 600 is moved to the right, and all of the auxiliary levers 512 coupled to the connector 600 are moved to the left, so that all of the power transmitters 400 coupled to the auxiliary levers 512 may be rotated counterclockwise.

[0575] When the power shaft 240 continuously rotates clockwise, the eccentric shaft 310 may also continuously rotate, and the aforementioned process may be repeated infinitely.

[0576] In one example, when the power shaft 240 continuously rotates counterclockwise, the eccentric shaft 310 may also continuously rotate counterclockwise, and the aforementioned process may be repeated infinitely in a reverse order.

[0577] As a result, the laundry may be shaken in the left and right direction centered on the support shaft 410 of the mounted power transmitter 400.

[0578] FIG. 24 shows an embodiment of supporting a driver in a moving hanger 100 of the present disclosure.

[0579] The support plate 810 is disposed to overlap the power transmitter 400. In this regard, the driver 200 is disposed to be spaced apart from the power transmitter 400 in the front and rear direction to secure a length for generating the rotational power or the torque that allows the power transmitter 400 perform the reciprocating rotational motion.

[0580] In this case, an area in one side of the driver 200 may be supported by being seated on the support plate 810, but a remaining area may be difficult to be seated on the support plate 810.

[0581] When the driver 200 is disposed at a rear portion of the support plate 810, there is a concern that a rear portion of the driver 200 may not be supported by the support plate 810 and may be supported by the top surface of the inner casing 20.

[0582] The motor 210 may include a first coupling portion 2141 that is seated on the support plate 810 and fixes the motor 210, and a second coupling portion 2142 that is spaced apart from the support plate 810 and fixes the motor 210.

[0583] The pulley support 234 may include a first fixing portion 2347 that is seated on the support plate 810 and fixes the pulley support, and a second fixing portion 2348 that is spaced apart from the support plate 810 and fixes the pulley support.

[0584] A separate motor support member 25 and a pulley support member 26 may be formed on the top surface of the inner casing 20 to support the motor 210 and the pulley support 234.

[0585] FIG. 25 shows an additional embodiment of supporting a driver in a moving hanger 100 of the present disclosure.

[0586] Because the top surface of the inner casing 20 is made of a resin-based material, there is a risk of damage when the vibration or the load is transmitted from the motor 210 and the pulley support 234.

[0587] Therefore, the support part 800 of the present disclosure may include an expansion plate 830 that may extend forward or rearward from the support plate 810 or may be coupled to a front portion or a rear portion of the support plate 810 to expand an area size of the support part 800.

[0588] (a) in FIG. 25 shows a structure in which the motor 210 and the pulley support 234 are supported by the support plate 810 and the expansion plate 830 in a shared manner, and (b) in FIG. 25 shows structures of the support plate 810 and the expansion plate 830.

[0589] The expansion plate 830 may extend from a rear surface or a front surface of the support plate 810 and be coupled to the support frame 12.

[0590] The expansion plate 830 may be formed in the same shape as the support plate 810.

[0591] The motor 210 and the pulley support 234 may be supported by the support plate 810 and the expansion plate 830 in the shared manner.

[0592] The motor 210 may include the first coupling portion 2141 that is seated on the support plate 810 and fixes the motor 210, and the second coupling portion 2142 that is spaced apart from the support plate 810 and seated on the expansion plate 830 and fixes the motor 210.

[0593] The pulley support 234 may include the first fixing portion 2347 that is seated on the support plate 810 and fixes the pulley support, and the second fixing portion 2348 that is spaced apart from the support plate 810 and seated on the expansion plate 830 and fixes the pulley support.

[0594] FIG. 26 shows another embodiment of supporting a driver in a moving hanger 100 of the present disclosure.

[0595] (a) in FIG. 26 shows a structure in which a support bar is disposed separately. (b) in FIG. 26 shows a configuration in which the support bar supports the driver 200.

[0596] The support part 800 of the present disclosure may include a separate support bar 870 that is disposed separately from the support plate 810, but supports the driver 200 in front of or at the rear of the support plate 810.

[0597] One side of the driver 200 may be supported by being seated on the support plate 810, and the other side of the driver 200 may be supported by being seated on the support bar 870.

[0598] The support bar 870 may be formed in a frame shape that is narrower than the support plate 810, and may be disposed to be spaced apart from the support plate 810. The driver 200 may be disposed in a space in which the support plate 810 and the support bar 870 are spaced apart from each other.

[0599] The motor 210 may include the first coupling portion 2141 that is seated on the support plate 810 and fixes the motor 210, and the second coupling portion 2142 that is seated on the support bar 870 by being spaced apart from the support plate 810 and fixes the motor 210.

[0600] The pulley support 234 may include the first fixing portion 2347 that is seated on the support plate 810 and fixes the pulley support, and the second fixing portion 2348 that is seated on the expansion plate 870 by being spaced apart from the support plate 810 and fixes the pulley support.

[0601] The motor 210 may be disposed to be further spaced apart from the support plate 810 than the pulley support 243.

[0602] To support such motor 210, the support bar 870 may include a first body 871 coupled to the support frame 12, a second body 872 extending obliquely from the first body and moving away from the support plate 810, a third body 873 extending from the second body 872 to the opposite support frame 12, a fourth body 874 extending from the third body 873 toward the pulley support 243, and a fifth body 875 extending from the fourth body 874 and seated and fixed on the opposite support frame 12.

[0603] The pulley support 243 may be supported by being coupled to the fifth body 875, and the driver 210 may be positioned between the first body 871, the second body 872, the third body 873, the fourth body 874, and the support plate 810, and may be supported by being seated on the support plate 810 and the third body 873.

[0604] FIG. 27 shows another embodiment of a moving hanger 100 of the present disclosure.

[0605] The moving hanger 100 of the present disclosure may be largely divided into the driver 200 and the transmitter 230 that generate and transmit the power, and the reciprocating rotating part 500, the connector 600, and the power transmitter 400 that move with the power.

[0606] The support part 800 may include a separate additional plate 840 supporting the driver 200 and the transmitter 230, and the support plate 810 supporting the reciprocating rotating part 500, the connector 600, and the power transmitter 400.

[0607] The additional plate 840 may be spaced apart from the support plate 810 and coupled and fixed to the support frame 12.

[0608] The additional plate 840 may be spaced apart from the support plate 810, thereby preventing vibration of the support plate 810 and vibration of the additional plate 840 from overlapping or interfering with each other.

[0609] The additional plate 840 may include an additional body 841 that supports the motor 210 and the transmitter 230, a frame body 843 that supports the additional body 841 to the support frame, and a connecting body 842 that connects the additional body 841 with the frame body 843.

[0610] The additional body 841 may be positioned downward of the frame body 843 to secure a space where the motor 210 and the transmitter 230 are seated, and the connecting body 842 may be positioned at an angle.

[0611] The additional body 841 may include an insertion hole 8411 into which the motor 210 is inserted, and a support groove 8412 into which an outer circumferential surface of the motor 210 is coupled and supported.

[0612] The additional body 841 may include a pulley hole 8413 spaced apart from the insertion hole 8411 and in which the pulley support 243 is seated. The pulley hole 8413 may have a diameter smaller than that of the pulley support 243 to support the pulley support 234, but may allow the power shaft 240 or the eccentric shaft 310 to pass therethrough as is.

[0613] The additional body 841 may be disposed upward of the support plate 810.

[0614] The power transmitter 400 may be supported by extending through the support plate 810, and the reciprocating lever 510 may be coupled to the power transmitter 400 to support the power transmitter 400 on the support plate 810.

[0615] The reciprocating levers 510 may include the main lever 511 that receives the power from the transmitter 230 and performs the reciprocating rotational motion, and the auxiliary levers 512 that are connected to the main lever 511 via the link bar 610 and rotate together with the main lever 511.

[0616] Unlike in the previous embodiment, the link bar 610 may connect a lower end of the main lever 511 with a lower end of the auxiliary lever 512.

[0617] The link bar 610 may include the link body 611 and the hook coupling portion 612 similar to the previous embodiment.

[0618] The link bar 610 may be disposed on an opposite side of the driver 200 or the transmitter 230 with respect to the support plate 810. As a result, the link bar 610 may be prevented from interfering with the driver 200 or the transmitter 230 and the displacement generator 300.

[0619] For example, the link bar 610 may be disposed either in front of or at the rear of the support plate 810, and the driver 200 and the transmitter 230 may be disposed on an opposite side of support plate 810.

[0620] As a result, the support plate 810 may be disposed between the connector 600 and the driver 200 to partition the connector 600 and the driver 200 from each other. Accordingly, while preventing the connector 600 and the driver 200 from interfering with each other, components may be stably Installed and arranged.

[0621] FIG. 28 shows another embodiment of a moving hanger 100 of the present disclosure.

[0622] Similarly to the previous embodiment, the moving hanger 100 of the present disclosure shown in FIG. 28 may allow the power transmitter 400 to perform the reciprocating rotational motion via the driver 200, the transmitter 230, and the reciprocating rotating part 500 to oscillate the hanger part 700 and the clothes hanger 900 hung on the power transmitter 400 and remove dust.

[0623] The connector 600 of the moving hanger 100 may connect the plurality of power transmitters 400 to each other, so that when one of the power transmitters 400 performs the reciprocating rotational motion, the remaining power transmitters 400 may also perform the reciprocating rotational motion

[0624] However, the connector 600 may include a plurality of links 620 that connect the plurality of power transmitters to each other.

[0625] For example, the plurality of links 620 may be disposed at front and rear portions of the power transmitters 400 and connect the power transmitters 400 to each other.

[0626] Specifically, the reciprocating rotating part 500 may be coupled to or extended from the power transmitter 400 upward of the support part 800 to rotate the power transmitter 400.

[0627] The plurality of links 620 may connect all of the reciprocating rotating parts 500 respectively disposed on the power transmitters 400 to each other, thereby connecting all of the power transmitters 400 to each other.

[0628] The plurality of links 620 may connect not only respective one ends or front portions of the reciprocating rotating parts 500 to each other, but also the other ends or rear portions of the reciprocating rotating parts 500 to each other.

[0629] Therefore, when one reciprocating rotating part 500 rotates, all the other reciprocating rotating parts 500 may rotate via the plurality of links 620, and the plurality of power transmitters 400 may rotate together.

[0630] Because the moving hanger 100 has the plurality of links 620 arranged on both sides or both the front and rear portions of the reciprocating rotating part 500, when the power of the driver 200 is received at the front or rear portion of the reciprocating rotating part 500, there is a concern that it may interfere with the plurality of links 620.

[0631] The moving hanger 100 may be equipped such that an upper portion of the reciprocating rotating part 500 receives the power of the driver 200. To this end, the reciprocating rotating part 500 may include a rotary rod 523 that may protrude or extend upward and may perform the reciprocating rotational motion by the driver 200.

[0632] The rotary rod 523 may be formed in a columnar or shaft shape, but may be formed in any shape as long as it is able to rotate a rotary plate 520.

[0633] The rotary rod 523 may be disposed in all of the reciprocating rotating parts 500, but may be disposed in only one reciprocating rotating part 500.

[0634] The power transmitter 400 may include the support shaft 410 that passes through the inner casing 20 and the support part 800 and performs the reciprocating rotational motion by the reciprocating rotating part 500.

[0635] The auxiliary support part 420 may be coupled to the lower portion of the support shaft 410. However, the hanger part 700 may be directly coupled to the lower portion of the support shaft 410.

[0636] The support shaft 410 and the reciprocating rotating part 500 may be eqiupped as separate members and coupled to each other, or the support shaft 410 and the reciprocating rotating part 500 may be equipped integrally.

[0637] The reciprocating rotating part 500 may be disposed at an upper end of the support shaft 410, and may have a diameter larger than that of the support shaft 410 and thus may easily rotate even with a small external force.

[0638] Therefore, when the rotary rod 523 rotates and one reciprocating rotating part 500 performs the reciprocating rotational motion, all of the reciprocating rotating parts 500 may be rotated by the plurality of links 620.

[0639] As a result, all of the power transmitters 400 may perform the reciprocating rotational motion based on the support shaft 410.

[0640] FIG. 29 shows a specific structure of a moving hanger 100 shown in FIG. 28.

[0641] The connector 600 may include the plurality of links 620 that connect the plurality of reciprocating rotating parts 500 to each other and rotate the plurality of reciprocating rotating parts 500 integrally.

[0642] The plurality of links 620 may be arranged to be spaced apart from each other to both sides of centers of rotation of the plurality of reciprocating rotating parts 500.

[0643] The plurality of links 620 includes a first link 621 connecting respective one sides of the plurality of reciprocating rotating parts 500 to each other and a second link 622 connecting the other sides of the plurality of reciprocating rotating parts 500 to each other and facing the first link.

[0644] Referring to (a) in FIG. 29, the reciprocating rotating part 500 may include the rotary plate 520 coupled to the upper end of the support shaft 410. The rotary plate 520 may be formed in a circular shape and may have a diameter larger than that of the support shaft 410.

[0645] However, as long as the rotary plate 520 is able to be connected to the plurality of links 620 and perform the reciprocating rotational motion, it may be equipped as the reciprocating lever 510.

[0646] The plurality of power transmitters 400 may be arranged to be spaced apart from each other by a certain distance along the length direction of the support part 800 or the width direction of the inner casing 20.

[0647] The rotary plate 520 may be coupled to the upper portion of the power transmitter 400 or extend from the upper portion of the power transmitter 400.

[0648] The rotary plate 520 may perform the reciprocating rotational motion relative to the power transmitter 400 at a location upward of the support part 800.

[0649] The support part 800 may include a seating plate 860 that may be seated on the support plate 810 to support the rotary plate 520 so as to support the reciprocating rotational motion of the rotary plate 520.

[0650] The seating plate 860 may be made of a resin-based material with a low friction force or a lubricating material, and may be seated on and fixed to the support plate 810.

[0651] The plurality of links 620 may connect all the one sides of the plurality of rotary plates 520 to each other and connect all the other sides thereof to each other, respectively. Because the plurality of rotary plates 520 are arranged to be spaced apart from each other in the width direction of the inner casing 20, the plurality of links 620 may connect all the front portions of the rotary plates 520 to each other and connect all the rear portions of the rotary plates 520 to each other, respectively.

[0652] The plurality of links 620 may include the first link 621 that connects the front portions of the plurality of rotary plates 520 to each other, and the second link 622 that connects the rear portions of the plurality of rotary plates 502 to each other. The first link 621 and the second link 622 may be coupled to an outer circumferential surface or an outermost surface of the rotary plate 520 to effectively rotate the rotary plate 520.

[0653] The rotary rod 523 that receives the power from the driver 200 may be disposed on one of the plurality of rotary plates 520.

[0654] The rotary rod 523 may extend upward of the one of the rotary plates 520, and may serve as the center of rotation of the rotary plate 520. The rotary rod 523 may be formed integrally with the support shaft 410, or may be disposed parallel to the support shaft 410.

[0655] A diameter of the rotary rod 523 may be set smaller than the diameter of the rotary plate 520.

[0656] Referring to (b) in FIG. 29, the driver 200 may rotate the rotary rod 523 at a location upward of the inner casing 20.

[0657] Specifically, the driver 200 may include the motor 210 supported by the support part 800, the power shaft 240 that rotates at the fixed location by the motor 210, and the displacement generator 300 that is coupled to the power shaft 240 and generates the displacement that allows the rotary rod 523 to rotate.

[0658] The displacement generator 300 may be coupled to the reciprocating rotating part 500 at a location between the first link 621 and the second link 622.

[0659] The displacement generator 300 may include a rotary arm 330 that has one end coupled to the rotary rod 534 and the other end rotatable along a predetermined radial trajectory by the rotation of the power shaft 240.

[0660] That is, the displacement generator 300 may be coupled to the rotary rod 534 corresponding to the center of rotation of the reciprocating rotating part 500.

[0661] Therefore, when the rotary arm 330 rotates along the predetermined radial trajectory, the rotary rod 523 may perform the reciprocating rotational motion.

[0662] FIG. 30 is an exploded perspective view of a moving hanger 100 shown in FIG. 28.

[0663] The number of power transmitters 400 and the number of rotary plates 520 may be equal to each other, and each rotary plate 520 may be disposed for each power transmitter 400.

[0664] The power transmitter 400 may include the support shaft 410 that passes through the support plate 810 and is exposed to the accommodating space 21.

[0665] The rotary plate 520 may be coupled to or integrally formed with the upper portion of the support shaft 410.

[0666] The rotary plates 520 may include a main rotary plate 521 coupled or extended to the support shaft 410 and including the rotary rod 523, and an auxiliary rotary plate 522 coupled or extended to the support shaft 410 that does not have the main rotary plate 521.

[0667] The main rotary plate 521 may be disposed only on one power transmitter 400, and the auxiliary rotary plates 522 may be installed on the remaining power transmitters 400.

[0668] The main rotary plate 521 and the auxiliary rotary plates 522 may be connected to each other by the plurality of links 620.

[0669] In other words, the reciprocating rotating parts 500 include the main rotary plate 521 that is coupled to the displacement generator 300 and performs the reciprocating rotational motion, and the auxiliary rotary plates 522 that are coupled to the remaining power transmitters spaced apart from the main rotary plate and rotate the power transmitters.

[0670] The first link 621 may connect one side of the main rotary plate and respective one sides of the auxiliary rotary plates to each other, and the second link 622 may connect the other side of the main rotary plate and the other sides of the auxiliary rotary plates to each other.

[0671] In other words, the first link 621 may connect the respective one sides of the main rotary plate 521 and the auxiliary rotary plates 522 based on the support shaft 410 to each other, and the second link 622 may connect the other sides of the main rotary plate 521 and the auxiliary rotary plates 522 based on the support shaft 410 to each other.

[0672] The first link 621 and the second link 622 may have the same length, and may have a length to connect all of the rotary plates 520 to each other.

[0673] The rotary plates 520 may include rotary plate holes 5211 and 5221 into which the fastening members coupled to the first link 621 and the second link 622 may be coupled.

[0674] Specifically, the main rotary plate 521 may include main rotary plate holes 5211 that are spaced apart from the support shaft 410 and the rotary rod 523 and are symmetric with each other around the support shaft 410 and the rotary rod 523. The main rotary plate holes 5211 may be defined close to the outer circumferential surface of the main rotary plate 521.

[0675] The auxiliary rotary plate 522 may include auxiliary rotary plate holes 5221 that are spaced apart from the support shaft 410 and are symmetric with each other around the support shaft 410. The auxiliary rotary plate holes 5221 may be defined close to the outer circumferential surface of the auxiliary rotary plate 522.

[0676] The plurality of links 620 may include link holes 623 through which rivets 524 that are inserted into and coupled with the rotary plate holes may extend. The number of link holes 623 may correspond to the number of power transmitters 400 arranged along the length of the first link 621 and the second link 622.

[0677] The first link 621 and the second link 622 may be set to have the same distance from the main rotary plate and the auxiliary rotary plate, respectively.

[0678] The first link 621 and the second link 622 may be coupled to the rotary plate 520 so as to always maintain a parallel state.

[0679] The main rotary plate 521 and the auxiliary rotary plate 522 may have the same length, diameter, or area size. The first link 621 and the second link 622 may be coupled to both ends of the main rotary plate and both ends of the auxiliary rotary plate, thereby rotating the main rotary plate 521 and the auxiliary rotary plate 522 at a larger angle with less motion.

[0680] The hanger part 700 may be coupled to a lower end of the support shaft 410. The hanger part 700 may include a hanging hole 710 coupled to the support shaft 410, and the stand groove 740 in which the ring 910 is seated in one of both sides of the hanging hole 710.

[0681] A lower clip 429 supporting a lower portion of the hanger part 700 may be coupled to the lower end of the support shaft 410, and an upper clip 428 supporting an upper portion of the hanger part 700 may be coupled to a middle portion of the support shaft 410.

[0682] In addition, the hanger part 700 may additionally include an extending member 760 that passes through one surface of the hanger to extend through the outer circumferential surface of the support shaft 410.

[0683] Accordingly, the hanger part 700 is firmly coupled to the support shaft 410, so that even when the hanger part 700 performs the reciprocating rotational motion in the left and right direction, the hanger part 700 may be prevented from rotating idly around the support shaft 410 or being removed from the support shaft 410.

[0684] The support shaft 410 may be equipped as a metal pipe to ensure durability. In one example, as long as the support shaft 410 is not twisted even by the rotational torque and is able to sufficiently support the loads of the hanger part 700, the clothes hanger 900, and the laundry, the support shaft 410 may be made of a resin-based material.

[0685] In addition, the support shaft 410 may have a diameter much smaller than that of the rotary plate 520 to minimize a rotational moment of inertia.

[0686] The support part 800 may include the auxiliary plate 880 that is seated on the support plate 810 and supports the rotary plate 520.

[0687] At least one of the rotary plate 520 and the auxiliary plate 880 may be made of a material having lower frictional force than metal. For example, both the rotary plate 520 and the auxiliary plate 880 may be made of a resin-based material.

[0688] The auxiliary plate 800 may include the auxiliary body 881 that is seated on the support part 800, the auxiliary through-hole 882 that allows the support shaft 410 to pass therethrough along the length direction of the auxiliary body 881, a retaining rib 883 that extends from an outer circumferential surface of the auxiliary through-hole 882 and the auxiliary body 881 to maintain the rigidity of the auxiliary plate 880, and a recessed space 884 that is recessed downward from the auxiliary body 881 to define a space where the load may be distributed between an inner peripheral surface of the auxiliary body 881 and the retaining rib 833.

[0689] The rotary plate 520 may be rotatably supported by the retaining rib 883 or the auxiliary through-hole 882. However, it is preferable that the rotary plate 520 rotates while being spaced apart from the auxiliary plate 800.

[0690] The support bearing 530 that rotatably supports the support shaft 410 may be seated on and fixed to the auxiliary through-hole 882.

[0691] FIG. 31 shows an operating principle of a moving hanger 100 shown in FIG. 28.

[0692] (a) in FIG. 31 shows operating states of the reciprocating rotating parts 500, the power transmitters 400, and the plurality of links 620 as viewed from above the support part 800, and (b) in FIG. 31 conceptually shows operations of the reciprocating rotating parts 500, the power transmitters 400, and the plurality of links 620.

[0693] First, the first link 621 and the second link 622 may be arranged to face each other based on the power transmitter 400. The first link 621 may be coupled to the respective one sides of the rotary plates 520 coupled to the power transmitters 400, and the second link may be coupled to the other sides of the rotary plates 520 coupled to the power transmitters 400.

[0694] One of the rotary plates 520 may be equipped as the main rotary plate 521 that directly receives the power from the driver 200 or the displacement generator 300, and the remaining rotary plates 520 may be equipped to receive the power from the main rotary plate 521 via the first link 621 and the second link 622.

[0695] The rotary plate 520 and the plurality of links 620 may be coupled to each other via the rivet 524.

[0696] When the power transmitters 400 are positioned at the correct locations, the clothes hangers 900 may be directed in the front and rear direction and may be positioned parallel to each other, and the rivet 524 coupled to the first link 621 and the rivet coupled to the second link 622 may be positioned to face each other.

[0697] The first link 621 and the second link 622 may reciprocate in the width direction of the inner casing.

[0698] The first link 621 may connect the respective one ends or one sides of the plurality of rotary plates 520 to each other and reciprocate in the width direction of the inner casing, and the second link 622 may connect the other ends or the other sides of the plurality of rotary plates 520 to each other and reciprocate in the width direction of the inner casing.

[0699] The first link 621 and the second link 622 may be coupled to the plurality of rotary plates 520 while being spaced apart from the centers of rotation thereof.

[0700] Therefore, when the driver 200 operates and the rotary plate 520 rotates, the first link 621 and the second link 622 may reciprocate in opposite directions.

[0701] When the driver 200 rotates the rotary rod 533 disposed on the main rotary plate 521 to the left or counterclockwise, the support shaft 410 connected to the main rotary plate 521 rotates to the left or counterclockwise.

[0702] Therefore, the hanger part 700 and the clothes hanger 900 may also rotate counterclockwise.

[0703] When the main rotary plate 521 rotates counterclockwise, the first link 621 moves to the left via the rivet 524, and the second link 622 moves to the right. In such process, the first link 621 and the second link 622 may come closer to each other.

[0704] The first link 621 rotates the auxiliary rotary plate 522 counterclockwise while moving to the left, and the second link 622 rotates the auxiliary rotary plate 522 counterclockwise while moving to the right.

[0705] Therefore, all of the power transmitters 400 connected to the auxiliary rotary plates 522 may rotate counterclockwise. As a result, all of the power transmitters 400 may rotate counterclockwise.

[0706] In such process, the power transmitter 400, the hanger part 700, and the clothes hanger 900 further rotate counterclockwise and are arranged to be biased to the right based on the front and rear direction.

[0707] When the driver 200 rotates the rotary rod 533 disposed on the main rotary plate 521 to the right or clockwise, the support shaft 410 connected to the main rotary plate 521 rotates to the right or clockwise.

[0708] Therefore, the hanger part 700 and the clothes hanger 900 may also rotate clockwise.

[0709] The main rotary plate 521 may rotate and be restored to an original location thereof, and the hanger part 700 and the clothes hanger 900 may also rotate clockwise and be restored to original locations thereof.

[0710] When the main rotary plate 521 rotates clockwise, it moves the first link 621 to the right and moves the second link 622 to the left via the rivet 524. In such process, the first link 621 and the second link 622 may gradually move apart from each other.

[0711] The first link 621 rotates the auxiliary rotary plate 522 clockwise while moving to the right, and the second link 622 rotates the auxiliary rotary plate 522 clockwise while moving to the left.

[0712] Therefore, all of the power transmitters 400 connected to the auxiliary rotary plates 522 may rotate clockwise. As a result, all of the power transmitters 400 may rotate counterclockwise.

[0713] In this regard, when the driver 200 further rotates the rotary rod 533 to the right or clockwise, the support shaft 410 connected to the main rotary plate 521 further rotates clockwise.

[0714] In such process, the first link 621 may further move to the right, and the second link 622 may further move to the left. In such process, the first link 621 and the second link 622 may become closer to each other again.

[0715] The first link 621 and the second link 622 rotate all of the auxiliary rotary plates 522 clockwise, and the power transmitters 400, the hangers 700, and the clothes hangers 900 connected to the auxiliary rotary plates 522 further rotate clockwise and are arranged to be biased to the left based on the front and rear direction.

[0716] When the rotary rod 523 repeatedly performs the reciprocating rotational motion clockwise and counterclockwise, all of the above-described processes may be repeated, and the power transmitter 400 may also perform the reciprocating rotational motion around the support shaft 410 together to remove dust from one side and the other side of the clothes hanger 900.

[0717] Because the power transmitted via the rotary rod 523 is transmitted to all of the rotary plates 520 via the plurality of links 620, the rotation of the rotary plates 520 may be accurately controlled.

[0718] In addition, the load transmitted from the rotary rod 532 may be distributed to the plurality of links 620 and transmitted to the rotary plates 520, so that the load may be prevented from being concentrated on one of the front and rear portions, or both sides of the rotary plate 520.

[0719] FIG. 32 shows a structure of a driver 200 that may allow a rotary rod 532 to perform a reciprocating rotational motion.

[0720] The rotary rod 532 may include the reciprocating lever 510 coupled to the rotary rod 532, and may perform the reciprocating rotational motion by the driver 200 that includes the eccentric shaft 310 that rotates the reciprocating lever 510.

[0721] However, a structure that may rotate the rotary rod 532 in a different manner from the structure of the driver 200 will be described below.

[0722] The driver 200 may include a horizontal motor 212 that is seated on the support part 800 and a horizontal rotation shaft 222 that is disposed on the horizontal motor to rotate, but rotates at an angle with the support shaft 410.

[0723] The horizontal rotation shaft 222 may extend in the front and rear direction and rotate.

[0724] The driver 200 may further include the transmitter 230 that may receive power of the horizontal rotation shaft 222 as it is, but may reduce an rpm thereof.

[0725] The transmitter 230 may rotate the power shaft 240 that transmits the power to the power transmitter 400.

[0726] The power shaft 240 may be disposed parallel to the horizontal rotation shaft 222, but may be rotated by the transmitter 230 when the horizontal rotation shaft 222 rotates.

[0727] Specifically, the transmitter 230 may include the transmission pulley 232 having a diameter much larger than that of the horizontal rotation shaft 222, and the belt 233 connecting the transmission pulley 232 with the horizontal rotation shaft 222.

[0728] The power shaft 240 may be coupled to the center of rotation of the transmission pulley 232, and the transmission pulley 232 and the power shaft 240 may be supported by the pulley support 234 coupled to the support part 800.

[0729] The pulley support 234 may be installed with a bearing that rotatably supports the power shaft 240.

[0730] The pulley support 234 may be formed in a shape of a tripod or the like that is seated on the support part 800 and extends upward, the transmission pulley 232 may be disposed at the rear of or in front of the pulley support 234, and a free end of the power shaft 240 may be disposed in front of or at the rear of the pulley support 234.

[0731] The moving hanger 100 may include the displacement generator 300 that may expand the rotation radius of the power shaft 240 to a predetermined radius that may allow the rotary rod 523 to perform the reciprocating rotational motion.

[0732] The displacement generator 300 may include an eccentric connector 320 that is coupled to the power shaft 240 at one end and rotates with a radius larger than that of the power shaft 240, and the rotary arm 330 that connects the other end of the eccentric connector 320 with the rotary rod 523.

[0733] The eccentric connector 320 may include a connector body 321 that is coupled to the power shaft 240, but has a free end that rotates along a predetermined trajectory, a connector hole 322 that passes through or is recessed into a distal end of the connector body 321 and allows the rotary arm 330 to be coupled thereto, and a power coupling hole 323 that is coupled to the power shaft 240 in the other surface located opposite to one surface of the connector body 321 in which the connector hole 322 is defined.

[0734] FIG. 33 shows a structure of the driver 200 in detail.

[0735] The horizontal motor 212 may rotate the horizontal rotation shaft 222.

[0736] The horizontal rotation shaft 222 may be coupled with the power pulley 231 that may rotate the belt 233 more smoothly and prevent removal of the belt 233.

[0737] The power shaft 240 may be coupled to the transmission pulley 232 and may support the pulley support 234 by extending therethrough.

[0738] The power shaft 240 and the horizontal rotation shaft 222 may be arranged in parallel with each other.

[0739] The connector 320 may be coupled to the power shaft 240 at a rear portion, and the rotary arm 330 may be coupled to a front portion of the connector 320.

[0740] The connector 320 may be coupled to the power shaft 240 to rotate integrally.

[0741] In the connector 320, the connector hole 322 coupled with the rotary arm 330 and the power coupling hole 323 coupled with the power shaft 240 may be defined to be spaced apart from each other by a predetermined length.

[0742] Therefore, when the connector 320 rotates, the connector hole 322 may rotate along a predetermined trajectory with a radius of the distance from the power coupling hole 323, and one end of the rotary arm 330 may also rotate along the predetermined trajectory.

[0743] The reciprocating rotating part 500 may further include a rod coupling portion 524 coupled to the rotary arm 330 and connecting the rotary rod 523.

[0744] The rod coupling portion 524 may rotatably support the rotary arm 330, but may be coupled to the rotary rod 523 and rotate the rotary rod 523 clockwise or counterclockwise based on the rotation of the rotary arm 330.

[0745] The rod coupling portion 524 may be made of a material having greater rigidity than the rotary rod 523, thereby rotating the rotary rod 523 while supporting the same without difficulty even when the rotary arm 330 rotates at a high rpm.

[0746] The rod coupling portion 524 may include a fixed coupling portion 5241 coupled to the rotary rod 523 to rotate the rotary rod 523, a rotary support board 5242 extending from both surfaces of the fixed coupling portion 5241 to rotatably support the rotary arm 330, and a link shaft 5243 extending through the rotary support board 5242 and the rotary arm 330 to fix the rotary arm 330 to the rotary support board 5242.

[0747] The link shaft 5243 may be directed in a horizontal direction, so that the rotary arm 330 may perform the reciprocating rotational motion in the vertical direction on the rotary support board 5242.

[0748] On the rod coupling portion 524, the rotary arm 330 may rotate in the vertical direction, and the rod coupling portion 524 may rotate in the left and right direction or clockwise / counterclockwise based on the support shaft 410 by the rotary plate 320.

[0749] The rotary arm 330 may include a coupling end 333 coupled to the connector 310, a rotary end 332 coupled to the rod coupling portion 524, and an arm body 331 that extends the coupling end and the rotary end.

[0750] The rotary support board 5242 may be formed in a shape of boards arranged on both sides of the rotary end 332, and may accommodate both surfaces of the rotary end 332 therebetween.

[0751] FIG. 34 shows an operating principle of the displacement generator.

[0752] The displacement generator 300 may rotate along a circular trajectory around the support shaft 410 or the reciprocating rotating part 500.

[0753] The reciprocating rotating part 500 may be fixed to the support shaft 410 and rotate only in the left and right direction.

[0754] Among the components of the displacement generator 300, the rotary arm 330 has one end coupled to the reciprocating rotating part 500 and the other end rotatable along the circular trajectory by the power shaft 240.

[0755] Among the components of the displacement generator 300, the eccentric connector 320 may be coupled to the power shaft 240 and may rotate a free end of the rotary arm 330 along the circular trajectory.

[0756] As a result, the rotary arm 330 may rotate along a conical trajectory when the power shaft 240 rotates.

[0757] A length of the rotary arm 330 may be greater than a length of the eccentric connector 320 or a rotation radius of the eccentric connector 320.

[0758] In this case, the rotary arm 330 may rotate more smoothly and rotate the reciprocating rotating part 500 and the power transmitter 400 in the left and right direction.

[0759] The length of the rotary arm 330 may be smaller than the rotation radius of the eccentric connector 320. In this case, a rotation angle of the rotary arm 330 becomes larger, so that the reciprocating rotating part 500 and the power transmitter 400 may perform the reciprocating rotational motion in the left and right direction more.

[0760] The connector body 321 of the connector 320 may extend in a direction different from an extension direction of the power shaft 240.

[0761] The connector body 321 may extend to one side or both sides from the power coupling hole 323 coupled with the power shaft 240. The connector body 321 may be disposed not to be parallel to the power shaft 240.

[0762] The power coupling hole 323 coupled with the power shaft 240 is defined in a rear surface of the connector body 321, so that the connector body 321 may rotate integrally with the power shaft 240.

[0763] In one example, the connector hole 322 into which the rotary arm 330 is coupled may be defined in a front surface of the connector body 321. The connector hole 322 and the power coupling hole 323 may be defined to be spaced apart from each other by a certain length. A center point of the connector hole 322 and a center point of the power coupling hole 323 may be defined to be spaced apart from each other along a length direction of the connector body 321.

[0764] As described above, the rotary arm 330 may have the coupling end 333 coupled to the power coupling hole 323 and the rotary end 332 coupled to the rotary support board 5242.

[0765] The connector 320 may further include a rotary bearing 324 coupled to the connector hole 322 to rotatably support the coupling end 333. The coupling end 333 may be formed in a pillar shape that is inserted into and fixed to the rotary bearing 324.

[0766] The rotary support board 5242 is fixed to the support rod 523 and is rotatable in a height direction or with respect to the support shaft 410 without changing a location and a vertical level thereof. Therefore, the rotary end 332 of the rotary arm 330 may be fixed in location with respect to the coupling end 333.

[0767] When the connector 320 rotates by the power shaft 240, the connector hole 332 rotates along a circular trajectory with a radius of a distance from the power coupling hole 323.

[0768] Therefore, the rotary arm 330 may rotate while the coupling end 333 draws a conical shape with respect to the rod coupling portion 524.

[0769] As the coupling end 333 rotates while drawing a circle, not only a vertical level but also a location in the left and right direction of the coupling end 333 change. The change in the vertical level of the coupling end 333 may be allowed as the rotary arm moves in the vertical direction on the rod coupling portion 524. The change in the left and right direction-location of the coupling end 333 generates a force that rotates the rod coupling portion 524 in the left and right direction.

[0770] The rod coupling portion 524 may perform the reciprocating rotational motion in the left and right direction based on the rotation of the coupling end 333, and the rotary rod 523 and the rotary plate 520 coupled to the rod coupling portion 524 may perform the reciprocating rotational motion in the left and right direction or clockwise and counterclockwise.

[0771] The connector 320 may further include the bearing 324 that rotatably supports the coupling end 333 of the rotary arm 330. The bearing 324 allows the coupling end 333 to freely rotate with respect to the connector 320, thereby ensuring that the connector 320 freely rotates together with the power shaft 240.

[0772] FIG. 35 shows a connection structure of a driver, a displacement generator, and a reciprocating rotating part in an embodiments in FIGS. 33 and 34.

[0773] (a) in FIG. 35 shows structures of the driver, the displacement generator, and the reciprocating rotating part, and (b) in FIG. 35 intuitively shows a location relationship between the displacement generator and the driver.

[0774] As described above, when an angle between the connector 320 and the arm body 331 or between the connector 320 and the power shaft 240 is freely variable, even when the arm body 331 rotates at any angle by the connector 320, the rod coupling portion 524, the rotary rod 523, and the power transmitter 400 may rotate clockwise and counterclockwise at the fixed locations without installation angles thereof being variable.

[0775] However, when a specific condition is satisfied, even when the angle between the connector 320 and the arm body 331 does not change and the angle between the connector 320 and the power shaft 240 is always fixed, the arm body 331 and the connector 320 may freely rotate 360 degrees based on the fixed rod coupling portion 524 and power shaft 240.

[0776] The rod coupling portion 524 and the power shaft 240 should be disposed at a vertical level h corresponding to each other. Alternatively, the rod coupling portion 524 should be disposed at a point parallel to the extension direction of the power shaft 240.

[0777] In other words, the center of rotation of the power shaft 240 and a center of rotation for the rod coupling portion 524 to rotate in the left and right direction do not need to coincide with each other.

[0778] In addition, the connector 320 and the arm body 331 should maintain a coupled state while forming a 90 degree angle with each other.

[0779] In one example, to maintain the angle of 90 degrees between the connector 320 and the arm body 331 coupled to each other, a length of the connector 320 and a length of the arm body 331 may be determined based on the distance between the free end of the power shaft 240 and the rod coupling portion 524. In addition, a location at which the coupling end 333 and the connector hole 322 are coupled to each other may also be determined at the same time.

[0780] As a result, when the connector 320 and the arm body 331 are maintained in the vertically connected state while the power shaft 240 and the rod coupling portion 524 or the rotary end 332 of the arm body 331 are arranged at the same vertical level, the angles between the arm body 331 and the connector 320 and between the connector 320 and the power shaft 240 may not vary, and the arm body 331 and the connector 320 may freely rotate 360 degrees.

[0781] FIG. 36 shows a process in which a displacement generator and a rotary arm in FIG. 35 continuously rotate without changing an angle at which they are connected.

[0782] Referring to (a) in FIG. 36, the driver 200 may rotate the power shaft 240 in the horizontal direction.

[0783] The rod coupling portion 524 or the rotary end 332 of the arm body 331 may be disposed on the extension direction of the power shaft 240. The rod coupling portion 524 or the rotary end 332 may be disposed at the same vertical level h as the power shaft 240.

[0784] The connector 320 and the arm body 310 may be coupled at a right angle to each other.

[0785] The arm body 310 may extend through the connector 320 and maintain the right angle with the connector 320, or may maintain the right angle with the connector 320 while the coupling end 333 is accommodated in the connector hole 332.

[0786] The power transmitter 400 or the support shaft 410 may be coupled to a lower portion of the rod coupling portion 524 and may rotate together with the rod coupling portion 524. The hanger part 700 may be disposed at the lower portion of the support shaft 410.

[0787] Based on the rotation radius of the arm body 330, the arm body 330 may be positioned at the lowest point, and the connector hole 332 of the connector 320 may also be positioned at a lower portion.

[0788] The power transmitter 400 and the hanger part 700 may be positioned to face the driver 200.

[0789] Referring to (b) in FIG. 36, when the power shaft 240 rotates counterclockwise, the connector 320 and the arm body 330 may rotate 90 degrees. The coupling end 333 may be positioned at an intermediate vertical level in the rotation trajectory and may be positioned at the leftmost location.

[0790] In this regard, the connector 320 and the arm body 330 may rotate without additionally receiving separate compressive force or tensile force while maintaining the coupled state. The rod coupling portion 524 may simply rotate to the left without varying an installation angle thereof by the rotation of the rotary arm 330. As a result, the power transmitter 400 may rotate to the left.

[0791] Referring to (c) in FIG. 36, when the power shaft 240 further rotates counterclockwise, the connector 320 and the arm body 330 may rotate 90 degrees.

[0792] In this regard, the connector 320 and the arm body 330 may rotate without additionally receiving the separate compressive force or tensile force while maintaining the coupled state.

[0793] In the arm body 330, the coupling end 333 may be disposed at the highest location.

[0794] The rod coupling portion 524 may simply rotate to the right without varying the installation angle thereof by the rotation of the rotary arm 330. As a result, the power transmitter 400 may rotate to the right. Again, the power transmitter 400 and the hanger part 700 may be disposed to face the power shaft 240.

[0795] Referring to (d) in FIG. 36, when the power shaft 240 further rotates counterclockwise, the connector 320 and the arm body 330 may rotate 90 degrees.

[0796] In this regard, the connector 320 and the arm body 330 may rotate without additionally receiving the separate compressive force or tensile force while maintaining the coupled state.

[0797] In the arm body 330, the coupling end 333 may be disposed at an intermediate location in the rotation trajectory and may be positioned at the rightmost location.

[0798] The rod coupling portion 524 may simply rotate to the right without varying the installation angle thereof by the rotation of the rotary arm 330. As a result, the power transmitter 400 may rotate to the right. Again, the power transmitter 400 and the hanger part 700 may be oriented further to the right when viewed from the front of the power shaft 240.

[0799] When the power shaft 240 rotates further, the above process may be repeated.

[0800] When the power shaft 240 rotates in an opposite direction, the above process may be performed in a reverse order.

[0801] When the rod coupling portion 524 rotates, the main rotary plate 521 may rotate, and the auxiliary rotary plates 522 may also rotate at the same time at the same angle as the reciprocating link 620 disposed on the main rotary plate 521 moves accordingly.

[0802] As a result, all of the power transmitters 400 may perform the reciprocating rotational motion.

[0803] FIG. 37 shows another embodiment of a connection structure of a displacement generator.

[0804] (a) in FIG. 37 shows structures of the driver, the displacement generator, and the reciprocating rotating part, and (b) in FIG. 37 intuitively shows a location relationship between the displacement generator and the driver.

[0805] Even when the rod coupling portion 524 rotates in the left and right direction, an angle between the support shaft 410 and the rotary plate 520 does not vary and is always maintained and fixed.

[0806] In addition, even when the power shaft 240 rotates, an angle of the power shaft 240 does not vary and is always maintained and fixed.

[0807] In such situation, when the angle between the rotary arm 330 and the connector 320 or the angle between the connector 320 and the power shaft 240 is able to vary, the rotary arm 330 may rotate while freely varying an installation angle thereof in the vertical direction and the left and right direction with respect to the rod coupling portion 524. As a result, the connector 320 and the rotary arm 330 may be freely designed based on installation conditions without being restricted in lengths, volumes, a coupling location, or a coupling angle.

[0808] To this end, the connector hole 322 of the connector 320 and the coupling end 333 may have a ball joint or ball bearing 3331 structure. Accordingly, the coupling end 333 may maintain the state of being connected to the connector 320 while freely varying an angle at which it is connected to the connector 320.

[0809] For example, the coupling end 333 may be formed as a circular end in the arm body 331, and the connector hole 332 may be defined in the arm body 331 to have a size or a volume corresponding to an outer shape of the coupling end 333.

[0810] Therefore, the coupling end 333 may freely move inside the connector hole 332 as the arm body 331 rotates. The arm body 331 and the connector 320 may repeatedly come closer to each other or move further apart from each other based on the coupling end 333.

[0811] As a result, even when the connector 320 and the arm body 331 have various lengths depending on necessity and circumstances, the power transmitter 400 may rotate in the left and right direction by rotating the rod coupling portion 524 in the left and right direction with the power shaft 240.

[0812] When necessary, the connector 320 and the power shaft 240 may be coupled to each other such that an angle therebetween may vary. For example, the free end of the power shaft 240 may be formed in a ball shape, and the power coupling hole may be defined in a shape that is coupled to the free end of the power shaft while accommodating the same therein. The power shaft 240 and the connector 320 may also be coupled to each other in the ball joint or ball bearing form to allow the angle therebetween to be varied.

[0813] As a result, a degree of freedom in the manufacturing lengths of the connector 320 and the arm body 331, a degree of freedom in the separation distance between the connector 320 and the rod coupling portion 524, and the like may be secured.

[0814] FIG. 38 shows another embodiment of a moving hanger 100.

[0815] The moving hanger 100 may have the same structure and principle of the driver 200 and the structures and principles of the power transmitter 400, the reciprocating rotating part 500, and the connector 600 as in the above-described embodiment.

[0816] Referring to (a) in FIG. 38, the power transmitter 400 may include the plurality of power transmitters arranged to be spaced apart from each other along the length direction of the support part 800, and the reciprocating rotating part 500 that rotates the power transmitter 400 may be disposed on the power transmitter 400.

[0817] The reciprocating rotating part 500 may be equipped as the rotary plate 520.

[0818] The connector 600 may be equipped as the plurality of links 620 to connect the plurality of rotary plates 520 to each other.

[0819] The displacement generator 300 may include the eccentric shaft 310 that is coupled to the power shaft 240 and rotates with a predetermined radius while drawing a trajectory larger than the rotation radius of the power shaft 240, a rod 340 that is coupled at one end to the eccentric shaft 310, and a cylinder 350 that is coupled to the rotary plate 520, rotates the rotary plate 520, and is coupled to the other end of the rod 340.

[0820] The eccentric shaft 310 may fix the rod 340 by being eccentric to one side from the rotation center of the power shaft 340.

[0821] The eccentric shaft 310 may protrude from a top surface of the power shaft 340, but may be formed in any shape as long as it may be coupled to one end of the rod 340.

[0822] The cylinder 350 may have a radius larger than the rotation radius of the eccentric shaft 310.

[0823] The cylinder 350 may be coupled to one of the plurality of rotary plates 520, and may have a diameter larger than that of the rotary plate 520.

[0824] The other end of the rod 340 may be coupled to a surface spaced apart from a center of rotation of the cylinder 350. The rod 340 may be coupled as close as possible to an outer circumferential surface of the cylinder 350 so as to rotate the cylinder 350 at a larger angle.

[0825] Referring to (b) in FIG. 38, the cylinder 350 may include a cylinder body 351 having a diameter larger than the rotation trajectories of the eccentric shaft 310 as well as the power shaft 240, and a cylinder shaft 352 disposed at a center of rotation of the cylinder body 351 and coupled to the center of rotation of the rotary plate 520.

[0826] The rotary plates 520 may be composed of the main rotary plate 521 that is coupled to the cylinder 350 and rotates, and the auxiliary rotary plates 522 that are separated from the cylinder 350 and rotate by the connector 600.

[0827] The cylinder shaft 352 may be coupled to a center of rotation of the main rotary plate 521.

[0828] The main rotary plate 521 may have the rotary rod 523 that protrudes in a shaft shape parallel to the support shaft 410, and the cylinder 350 may have the cylinder shaft 352 fixed to and coupled to the rotary rod 523.

[0829] Accordingly, when the cylinder 350 rotates, the rotary rod 523 may be rotated, and the support shaft 410 located under the main rotary plate 521 may be rotated. In addition, when the main rotary plate 521 rotates, the plurality of links 620 may rotate the auxiliary rotary plates 522 to rotate the support shafts 410 located under the auxiliary rotary plates 522.

[0830] FIG. 39 shows an operating principle of a moving hanger 100 in FIG. 38.

[0831] When the power shaft 240 rotates, the eccentric shaft 310 may rotate along a circular trajectory with an eccentric radius t1.

[0832] The rod 340 may include one end 342 of the rod coupled to the eccentric shaft 310, the other end 343 of the rod coupled to the cylinder 350, and a rod body 341 connecting the one end and the other end of the rod.

[0833] A length of the rod body 341 may be much greater than the eccentric radius t1 of the eccentric shaft 310.

[0834] The one end 342 of the rod may reciprocally move the rod body 341 and the other end 343 of the rod while rotating along the eccentric shaft 310.

[0835] The other end 343 of the rod may be rotatably coupled to a top surface of the cylinder body 351. A cylinder coupling portion 353 to which the other end 343 of the rod is coupled may be disposed on the top surface of the cylindrical body 351.

[0836] The cylinder coupling portion 353 may be disposed to be spaced apart from the center of rotation of the cylindrical body 351 by a reciprocating radius t2.

[0837] The reciprocating radius t2 may be smaller than a length of the rod body 341.

[0838] Accordingly, when one end 342 of the rod rotates along the eccentric shaft 310, the other end 343 of the rod may reciprocally move the cylinder coupling portion 353 based on the movement of the eccentric shaft 310.

[0839] As a result, the cylinder body 351 may perform the reciprocating rotational motion by an angle d based on the cylinder shaft 352, and the power transmitter 400 may reciprocally move by an angle d.

[0840] FIG. 40 shows an operating process of a moving hanger 100 in FIG. 38.

[0841] Referring to (a) in FIG. 40, the power shaft 240 rotates together with the transmitter 230. The eccentric shaft 310 may rotate along a rotation radius of the outer circumferential surface of the power shaft 240.

[0842] The eccentric shaft 310 may be disposed close to the cylinder 350 based on the power shaft 340. As a result, the rod 340 may push the cylinder coupling portion 353 away from the power shaft 240.

[0843] Referring to (b) in FIG. 40, the power shaft 240 may rotate to rotate the eccentric shaft 310 to a location farthest from the cylinder 350. As a result, the rod 340 may pull the cylinder coupling portion 353 and rotate the cylinder body 351.

[0844] When the cylinder body 351 rotates, the main rotary plate 521 may rotate, and the plurality of links 620 may move in a staggered manner to rotate the auxiliary rotary plate 522.

[0845] FIG. 41 shows another embodiment of a moving hanger 100.

[0846] It may be understood that the cylinder 350 of the displacement generator 300 in the moving hanger 100 shown in FIG. 38 is replaced with an additional rod 360.

[0847] The moving hanger 100 may have the same structure and principle of the driver 200 and the structures and principles of the power transmitter 400, the reciprocating rotating part 500, and the connector 600 as in the above-described embodiment.

[0848] The displacement generator 300 may include the rod 340 having one end that is coupled to the eccentric shaft 310 and rotates, and the additional rod 360 having one end coupled to the reciprocating rotating part 500 and the other end coupled to the other end of the rod 340.

[0849] The rod 340 coupled to the eccentric shaft 310 may be defined as a power rod 340 because it receives the power, and the additional rod 360 may be defined as a rotating rod 360 because it rotates the reciprocating rotating part 500.

[0850] The power rod 340 and the rotating rod 360 may operate like a four-bar link.

[0851] The reciprocating rotating part 500, the power transmitter 400, and the connector 600 may have the same structures as those in the moving hanger in FIG. 35.

[0852] In one example, the driver 200 may have the same structure and principle as those of the driver 200 in FIG. 34. However, the driver 200 may only have an installation location varied so as to be effectively supported by the support part 800.

[0853] The support part 800 may be disposed upward of the power transmitter 400, the reciprocating rotating part 500, and the connector 600. The power transmitter 400, the reciprocating rotating part 500, and the connector 600 may be disposed downward of the support part 800 and upward of the top surface of the inner casing 20.

[0854] The power transmitter 400, the reciprocating rotating part 500, and the connector 600 may be disposed between the support part 800 and the inner casing 20.

[0855] Accordingly, an area in which the transmitter 230 or the motor 210 may be installed may be secured on the support part 800.

[0856] Both the transmitter 230 and the motor 210 may be disposed on the support plate 810, but to secure the length of the belt 233 and expand the diameter of the transmission pulley 232, the motor 210 may be disposed on the additional plate 860 spaced apart from the support plate 810, and the transmitter 230, which receives the power from the motor 210, may be installed on the support plate 810.

[0857] The transmitter 230 disposed on the support plate 810 may be equipped with the transmission pulley 232 on the pulley support 234.

[0858] The power shaft 240 corresponding to the center of rotation of the transmission pulley 232 may be disposed on the transmission pulley 232.

[0859] The eccentric shaft 310 may be coupled with the power shaft 240 at a portion spaced apart from the center of rotation of the power shaft 240 and rotate along the inner circumferential surface of the power shaft 240.

[0860] The additional rod 360 may rotate the reciprocating rotating part 500 located at the very end to secure a rotational length of the power rod 340. The main rotary plate 521 may be equipped on a power transmitter 400 located at the very end, and the auxiliary rotary plates 522 may be equipped on the remaining power transmitters 400.

[0861] The displacement generator 300 may further include a rotary coupling shaft 370 that may be coupled to the other end 363 of the additional rod 360 and may be coupled to the rotary rod 523 through the support part 800 to rotate the rotary rod 523.

[0862] The power rod 340 includes one end 342 that is rotatably coupled to the eccentric shaft 310, the other end 343 that is coupled to the rotating rod 360, and the power rod body 341 that connects them to each other.

[0863] The rotating rod 360 may include one end 362 that is rotatably coupled to the other end 343 of the power rod, the other end 363 that rotates the rotary coupling shaft 370, and a rotating rod body 361 that connects them to each other.

[0864] FIG. 42 shows an operating principle of a moving hanger 100 in FIG. 40.

[0865] A length a2 of the power rod body 341 may be greater than a rotation radius a1 of the eccentric shaft 310.

[0866] A length a3 of the rotating rod body 361 may be set smaller than the length a2 of the power rod body 341. The length a3 of the rotating rod body 361 may be greater than the rotation radius a1 of the eccentric shaft 310.

[0867] When the power shaft 240 rotates, the eccentric shaft 310 rotates continuously. One end 342 of the power rod 340 rotates continuously with the eccentric shaft 310.

[0868] However, the other end 343 of the power rod 340 only reciprocates within a certain range d because of a length of the power rod body 341 and the other end 343 being coupled to the rotating rod 360, and is not able to rotate completely 360 degrees.

[0869] One end 362 of the rotating rod 360 may perform the reciprocating rotational motion at the certain angle d together with the other end 343 of the power rod 340.

[0870] FIG. 43 shows an operating process of a moving hanger 100 in FIG. 41.

[0871] Referring to (a) in FIG. 43, on the power shaft 240, the eccentric shaft 310 may be disposed at a location furthest from the rotation coupling shaft 370.

[0872] As a result, the power rod 340 may be coupled to the eccentric shaft 310 and pull the rotating rod 360. As a result, the rotary coupling shaft 370 may rotate counterclockwise.

[0873] Referring to (b) in FIG. 43, when the power shaft 240 rotates, the eccentric shaft 310 may be disposed closest to the rotary coupling shaft 370. As a result, the power rod 340 may be pushed in a direction in which the rotating rod 360 is positioned, and the power rod 340 may push the rotating rod 360 away from the eccentric shaft 310. As a result, the rotary coupling shaft 370 may rotate clockwise.

[0874] When the power shaft 240 continuously rotates in one direction, the process may be performed repeatedly.

[0875] As a result, the rotating rod 360 may perform the reciprocating rotational motion around the rotary coupling shaft 370 by the predetermined angle d like a handle or a lever. When the rotary coupling shaft 370 performs the reciprocating rotational motion, the power transmitter 400 located under the main rotary plate 521 may perform the reciprocating rotational motion by rotating the rotary rod 523 of the main rotary plate 521.

[0876] When the main rotary plate 521 performs the reciprocating rotational motion, the auxiliary rotary plate 522 may also perform the reciprocating rotational motion at the same time at the same angle as the main rotary plate 521 by the connector 600. The power transmitter 400 located under the auxiliary rotary plate 522 may also perform the reciprocating rotational motion.

[0877] Therefore, all of the power transmitters 400 may perform the reciprocating rotational motion by the angle d at which the rotary coupling shaft 370 performs the reciprocating rotational motion at the fixed locations based on the support shaft 410.

[0878] FIG. 44 shows another embodiment of a moving hanger 100.

[0879] A structure and a principle of the driver 200 and structures and principles of the power transmitter 400, the reciprocating rotating part 500, and the connector 600 may be the same as those in the above-described embodiment.

[0880] However, unlike other embodiments of the moving hanger, in the moving hanger 100 shown in FIG. 44, the reciprocating rotating part 500 and the connector 600 may be connected to each other by a rack and pinion structure or a gear coupling structure.

[0881] For example, the reciprocating rotating part 500 may include a rotary gear 540 that is coupled to the power transmitter 400 and rotates integrally with the power transmitter 400.

[0882] The connector 600 may include a rod gear 630 that may move by being engaged with the rotary gear 540.

[0883] The rod gear 630 may not be coupled to the rotary gear 540 via a separate fastening member, but may have one surface in contact with or being engaged with the rotary gear 540. As a result, the structures of the connector 600 and the reciprocating rotating part 500 may be simplified.

[0884] The rotary gear 540 may be coupled to an upper end of each power transmitter 400. The rotary gear 540 may be formed in a circular shape, the support shaft 410 may be coupled to a center of rotation of the rotary gear 540, and rotary gear teeth 542 may be disposed along an outer circumferential surface.

[0885] The rotary gear 540 may have a gear center hole 543 into which the support shaft 410 is coupled at a center thereof. The gear center hole 543 may be coupled to the screw thread or the like disposed on the support shaft 410.

[0886] Alternatively, the support shaft 410 may extend through the gear center hole 543, and may adhere to the rotary gear 540 as a separate fastening member is coupled thereto, so that the rotary gear 540 and the support shaft 410 may be coupled to each other. The center hole of the rotary gear 540 may be formed in a polygonal shape like a cross-sectional shape of the support shaft 410.

[0887] The rotary gear 540 may rotate when the support shaft 410 rotates, and the support shaft 410 may rotate when the rotary gear 540 rotates.

[0888] The rotary gears 540 may all have the same size and shape. Therefore, product compatibility and assembling efficiency may be improved.

[0889] The rod gear 630 may have a length to be engaged with all of the rotary gears 540. The rod gear 630 may have rod gear teeth 631 that may be engaged with the rotary gear teeth 541 at one side.

[0890] The rod gear 630 and the rotary gear 540 may both be disposed on the support part 800.

[0891] The rod gear 630 may perform a reciprocating linear motion only along the width direction of the inner casing 20. To this end, the support part 800 may further include a removal prevention step 890 disposed on the support plate 810 or the like to prevent the rod gear 630 from being removed or deviated from the rotary gear 540.

[0892] The driver 200 may directly rotate the rotary gear 540.

[0893] Specifically, the rotation shaft 220 or the power shaft 240 may directly rotate a center of rotation of the rotary gear 540 or the support shaft 410.

[0894] For example, the rotation shaft 220 and the power shaft 240 may be inserted into the gear center hole 542 of the rotation gear 540 to rotate the rotary gear 540. Alternatively, the rotation shaft 220 and the power shaft 240 may be coupled to the support shaft 410 to rotate the rotary gear 540 while rotating the support shaft 410.

[0895] The motor 210 may allow rotary gear 540 to perform the reciprocating rotational motion while allowing the transmitter 230 or the rotation shaft 220 to perform the reciprocating rotational motion at a certain angle.

[0896] When the rotary gear 540 connected to the motor 210 or the transmitter 230 rotates, the power transmitter 400 coupled to the rotary gear 540 also rotates.

[0897] In addition, when the rotary gear 540 rotates, the rod gear 630 engaged therewith may be moved, and the rod gear 630 may rotate another rotary gear 540. Accordingly, the power transmitters 400 coupled to other rotary gears 540 may also rotate.

[0898] Because the moving hanger 200 is equipped such that the driver 200 directly rotates the reciprocating rotating part 500, the displacement generator 300 that generates a greater displacement than the power shaft 240 may be omitted.

[0899] All of the embodiments of the moving hanger 100 described so far have in common that the displacement generator 300 is connected to the driver 200 to receive the power, and the displacement generator 300 transmits the power only to some of the reciprocating rotating parts 500.

[0900] The connector 600 connects the plurality of reciprocating rotating parts 500 to each other and transmit the power transmitted to some of the reciprocating rotating parts 500 that receive the power from the displacement generator 300 to the remaining reciprocating rotating parts 500.

[0901] Because of the connector 600, the plurality of reciprocating rotating parts 500 may rotate simultaneously, and as a result, the power transmitters 400, the hangers 700, and the clothes hangers 900 may all perform the reciprocating rotational motion.

[0902] In this regard, the connector 600 may connect respective portions that are spaced apart from the centers of rotation of the plurality of reciprocating rotating parts to each other. Accordingly, when the connector 600 reciprocates along the direction in which the reciprocating rotating parts 500 are arranged, because the centers of rotation of the reciprocating rotating parts 500 are spaced apart from the connector 600, the reciprocating rotating parts 500 may rotate.

[0903] However, in a moving hanger 100 of an embodiment to be described below, the connector 600 may directly receive the power from the driver 200 or the displacement generator 300 and rotate all of the reciprocating rotating parts 500.

[0904] FIG. 45 shows another embodiment of the moving hanger 100.

[0905] All of the moving hangers 100 in the above-described embodiments are equipped in such a way that the driver 200 transmits the power to some of the reciprocating rotating parts 500 respectively coupled with the power transmitters 400, and transmits the power to the remaining reciprocating rotating parts 500 via the connector 600.

[0906] That is, the power transmitted to some of the reciprocating rotating parts 500 is transmitted to the remaining reciprocating rotating parts 500 via the connector 600, so that all of the reciprocating rotating parts 500 and all of the power transmitters 400 rotate simultaneously.

[0907] However, the moving hanger 100 in the present embodiment may be equipped in such a way that the driver 200 transmits the power to the connector 600 to rotate all of the reciprocating rotating parts 500.

[0908] The driver 200 may reciprocate the connector 600 in a linear manner, and may rotate all of the reciprocating rotating parts 500 connected to the connector 600 to rotate all of the power transmitters 400.

[0909] The reciprocating rotating part 500 may include the rotary gear 540 that is coupled to the support shaft 410, rotates around the support shaft 410, and rotates together with the support shaft 410.

[0910] The number of rotary gears 540 may correspond to the number of power transmitters 400, so that the rotary gear 540 may be coupled to each support shaft 410.

[0911] The rotary gear 540 may include a rotary gear hole 542 through which the rotation shaft 410 passes and the rotary gear teeth 541 disposed along the outer circumferential surface.

[0912] The connector 600 may include the rod gear 630 that connects the plurality of rotary gears 540 to each other.

[0913] A length of the rod gear 630 may correspond to a length that may connect the plurality of rotary gears 540 to each other, and one surface of the rod gear 630 may include the rod gear teeth 631 that are engaged with the rotary gear teeth 541.

[0914] The displacement generator 300 may have the eccentric shaft 310 that passes through and is inserted into the rod gear 630. The motor 210 may rotate the transmitter 230, and the eccentric shaft 310 may rotate together with the transmitter 230.

[0915] In one example, the reciprocating rotating part 500 may further include the reciprocating lever 510 that is coupled to the support shaft 410 and rotates together with the support shaft 410. The reciprocating lever 510 may be disposed under the rotary gear 540 and support the connector 600.

[0916] Because the reciprocating lever 510 does not need to receive the power from the driver 200, it may be equipped as the auxiliary lever 512.

[0917] In one example, the connector 600 may include the removal prevention step 890 that supports one surface of the rod gear 630 to prevent the rod gear 630 from being removed from the rotary gear 540 when the rod gear 630 reciprocates by the eccentric shaft 310.

[0918] The removal prevention step 890 may be coupled to the support plate 810 or may be formed integrally with the support plate 810, and may support one surface of the rod gear 630.

[0919] FIG. 45 is an exploded perspective view of the moving hanger 100 shown in FIG. 43.

[0920] The rod gear 630 may include a gear body 631 having a length that may connect all of the rotary gears 540 to each other, a slit 632 that passes through the gear body 631 and into which the eccentric shaft 310 is inserted, and rod gear teeth 633 that are disposed on one side surface of the gear body 631 to be engaged with the rotary gear teeth 542.

[0921] The slit 632 may be defined perpendicular to a length direction of the gear body 631. The slit 632 may be defined perpendicular to a direction in which the gear body 631 reciprocates. The slit 632 may have a small width in the length direction of the gear body 631 and have a great width in the width direction of the gear body 631.

[0922] The driver 200 may include the motor 210 that rotates the rotation shaft 220 and the transmitter 230 that transmits the power of the rotation shaft 220, and the power shaft 240 may be disposed at a center of rotation of the transmitter 230. The eccentric shaft 310 may be disposed on the power shaft 240, and the eccentric shaft 310 may be inserted into the slit 632.

[0923] A diameter of a predetermined rotation trajectory of the eccentric shaft 310 may be smaller than or equal to the width of the slit 632.

[0924] FIG. 46 shows an operating principle of a moving hanger 100 shown in FIG. 43.

[0925] Referring to (a) in FIG. 46, the eccentric shaft 310 may move to the right while rotating and push the slit 632 to the right. In this regard, the rod gear 630 moves to the right (No. 1).

[0926] When the rod gear 630 moves to the right, all of the rotary gears 540 may rotate counterclockwise at the same time (No. 2). In this regard, when the reciprocating lever 510 is also equipped in addition to the rotary gear 540, the reciprocating lever 510 also rotates counterclockwise.

[0927] When the rotary gear 540 rotates counterclockwise, the support shaft 410 coupled thereto may rotate in the same manner and may rotate counterclockwise.

[0928] Referring to (b) in FIG. 46, the eccentric shaft 310 may continuously rotate in one direction and move to the left, thereby pushing the slit 632 to the left. In this regard, the rod gear 630 moves to the left (No. 1).

[0929] When the rod gear 630 moves to the left, all of the rotary gears 540 may rotate clockwise at the same time (No. 2). In this regard, when the reciprocating lever 510 is also equipped in addition to the rotary gear 540, the reciprocating lever 510 also rotates clockwise.

[0930] When the rotary gear 540 rotates clockwise, the support shaft 410 coupled thereto may rotate in the same manner and may rotate clockwise.

[0931] When the eccentric shaft 310 rotates continuously, the above process may be repeated, and the rod gear 630 may perform the linear motion in the left and right direction and be engaged with the plurality of rotary gears 540 to allow the plurality of rotary gears 540 to perform the reciprocating rotational motion simultaneously.

[0932] In such process, the eccentric shaft 310 may rotate in one direction without stopping, so that the output of the driver 200 may be completely transmitted to the rod gear 630 and the rotary gears 540.

[0933] As a result, all of the power transmitters 400 may receive sufficient torque and perform the reciprocating rotational motion in the left and right direction or clockwise / counterclockwise.

[0934] FIG. 47 shows another embodiment of a moving hanger 100.

[0935] Unlike the moving hanger 100 described above, the connector 600 may have a portion that receives the power from the driver 200 and a portion that rotates the reciprocating rotating part 500 set to be the same. In addition, the driver 200 may directly rotate the connector 600.

[0936] Referring to (a) in FIG. 47, the connector 600 may include a rack gear 640 that may move directly by the driver 200 and may rotate the reciprocating rotating part 500.

[0937] The reciprocating rotating part 500 may include the rotary gear 540 coupled to the upper portion of the power transmitter 400. The rack gear 640 may include a rack gear body 641 that may be disposed on the rotary gear 540 and may shield a portion of an upper portion of the rotary gear 540, and rack gear teeth 642 that may be disposed on a lower portion of the rack gear body 641 and may be engaged with the rotary gear teeth 541 of the rotary gear 540 and the rotation shaft 220 of the driver 200.

[0938] The rack gear teeth 642 may be disposed adjacent to one of a front surface and a rear surface of the lower portion of the rack gear body 641.

[0939] A length of the rack gear teeth 642 may be set to be equal to a length of the rack gear body 641. A width of the rack gear teeth 642 may be smaller than a width of the rack gear body 641.

[0940] Referring to (b) in FIG. 47, the rack gear teeth 642 may protrude from the lower portion of the rack gear body 641. The rack gear teeth 642 may be engaged with an upper portion of the rotary gear teeth 541.

[0941] In addition, the rack gear teeth 642 may face a side surface of the rotary gear 540 and be engaged with a side surface of the rotary gear teeth 541.

[0942] A length of the rack gear body 641 may correspond to a length that allows the rack gear teeth 642 to be engaged with all of the rotary gears 540. The width of the rack gear body 641 may be set so as to shield a portion of the rotary gear 540 or the support shaft 410 when the rack gear teeth 642 are engaged with some of the rotary gear teeth 541.

[0943] The rack gear body 641 may be seated on the rotary gear 540 and reciprocate in the left and right direction.

[0944] The driver 200 may include the horizontal motor 212 seated on the support part 800 and the rotation shaft 220 that rotates by the horizontal motor 212. A shaft gear 222 that may be engaged with the rack gear teeth 642 may be coupled to the outer circumferential surface of the rotation shaft 220.

[0945] The horizontal motor 212 may be disposed on one side of the rotary gear 540 and may be disposed at a vertical level that overlaps the rotary gear 540. In addition, both the horizontal motor 212 and the rotary gear 540 may be disposed downward of the rack gear 640.

[0946] Therefore, a height and a volume of the entire driver 200 may be reduced.

[0947] The rack gear body 641 may shield an upper portion of the horizontal motor 212. The rack gear body 641 may be supported on a top surface of the horizontal motor 212.

[0948] The reciprocating rotating part 500 may further include the reciprocating lever 510 disposed under the rotary gear 540. The reciprocating lever 510 may be coupled to the support shaft 410 to support the rotary gear 540.

[0949] The reciprocating lever 510 may have a diameter greater than a diameter of the rotary gear 540.

[0950] The reciprocating lever 510 may be coupled to the support shaft 410, but may have a length to be exposed to the outside of the rack gear 640. Therefore, the reciprocating lever 510 may hit an adjacent reciprocating rotating part 500 or the like when the rotary gear 540 rotates excessively.

[0951] Thus, the reciprocating lever 510 may limit an angular range in which the rotary gear 540 rotates or an angular range in which the rack gear 660 rotates.

[0952] That is, when the rotary gear 540 tries to rotate beyond the set angular range, the free end of the reciprocating lever 510 may be blocked by an adjacent reciprocating lever 510 or rotary gear 540, thereby preventing further rotation. As a result, collision between the clothes hangers 900 or the laundry pieces caused by the excessive rotation of the power transmitter 400 beyond the set rotation angle may be prevented.

[0953] The rotary gear 540 may rotate the reciprocating lever 510 by the rack gear 640, and the reciprocating lever 510 may rotate the support shaft 410.

[0954] FIG. 48 shows an operating principle of a moving hanger shown in FIG. 47.

[0955] Referring to (a) in FIG. 48, when the horizontal motor 212 rotates the rotation shaft 220 to the left, the rack gear teeth 641 engaged with the rotation shaft 220 move to the left. When the rack gear teeth 641 move to the left, the entire rack gear 640 moves to the left (No. 1).

[0956] In such process, the rotary gear 540 may rotate clockwise around the support shaft 410 by being engaged with the rack gear teeth 641 (No. 2).

[0957] The angle at which the rotary gear 540 rotates may increase in proportion to a length by which the rack gear 640 moves.

[0958] Referring to (b) in FIG. 48, when the horizontal motor 212 rotates the rotation shaft 220 to the right, the rack gear teeth 641 engaged with the rotation shaft 220 move to the right. When the rack gear teeth 641 move to the right, the entire rack gear 640 moves to the right (No. 1).

[0959] In such process, the rotary gear 540 may rotate counterclockwise around the support shaft 410 by being engaged with the rack gear teeth 641 (No. 2).

[0960] The angle at which the rotary gear 540 rotates may increase in proportion to the length at which the rack gear 640 moves.

[0961] When the above process is repeated, the power transmitter 400 may perform the reciprocating rotational motion clockwise and counterclockwise.

[0962] The driver 200 may alternately rotate the rotation shaft 220 clockwise and counterclockwise, and may rotate the same only when necessary, so that the angle at which the power transmitter 400 rotates may be precisely controlled.

[0963] In addition, because the displacement generator 300 having the eccentric shaft 310 or the power shaft 240 that rotates with a larger radius than the rotation shaft 220 may be omitted, the configuration of the driver 200 may be simplified.

[0964] In addition, because the rack gear 640 may exclude installation of the separate driver 200 thereon as much as possible, the volume of the entire moving hanger 100 may be reduced and ease of assembly thereof may be enhanced.

[0965] In addition, the rack gear 640 may prevent the driver 200 and the reciprocating rotating part 500 from being exposed to the outside, and may also prevent the components of the moving hanger 100 from being separated and removed in advance.

[0966] As a result, the moving hanger 100 may be equipped such that the rack gear 640 receives the power from the driver 200 and performs the reciprocating linear motion. The rack gear 640 may transmit the power of the driver 200 to the plurality of rotary gears 540.

[0967] The rack gear 540 may allow the plurality of rotary gears 540 to perform the reciprocating rotational motion while performing the reciprocating linear motion. The above power transmitter 400 may perform the reciprocating rotational motion.

[0968] FIG. 49 shows another embodiment of a moving hanger 100.

[0969] The moving hanger in FIG. 49 has almost the same configuration as the moving hanger in FIG. 44, so that a following description will focus on differences therebetween.

[0970] The moving hanger 100 may not include the displacement generator 300, and may directly rotate one of the support shafts 410 via the power shaft 240.

[0971] When the support shaft 410 is rotated, the rotary gear 540 coupled to the support shaft 410 is rotated, and the rotary gear 540 moves the rod gear 630. The rod gear 630 is supported by the removal prevention step 890, and thus is able to move linearly.

[0972] The rod gear 630 may rotate all of the rotary gears 540 that are engaged with the gear teeth 631, and thus may eventually rotate all of the support shafts 410 that are not in direct contact with the driver 200.

[0973] When the motor 210 changes the rotation direction thereof, the power shaft 240 may also change the rotation direction thereof, and as a result, the movement directions of the support shaft 410 and the rod gear 630 may be different from each other.

[0974] FIG. 50 shows another embodiment of a moving hanger 100.

[0975] The moving hanger 100 may include the hanger part 700 that hangs the laundry in the accommodating space, the power transmitter 400 that supports the hanger part 700 and allows the hanger part 700 to perform the reciprocating rotational motion, the driver 200 that provides the power to allow the power transmitter 400 to perform the reciprocating rotational motion, and the reciprocating rotating part 500 that receives the power from the driver 200 and allows the power transmitter 400 to perform the reciprocating rotational motion.

[0976] The power transmitter 400 may include the plurality of power transmitters arranged at a predetermined distance apart from each other along the length direction of the support part 800.

[0977] The moving hanger 100 may include the connector 600 that connects the plurality of power transmitters 400 to each other to rotate the power transmitters 400 simultaneously.

[0978] The driver 200 may include the motor 210 that generates the power and the rotation shaft 220 that rotates by the motor 210 to transmit the power.

[0979] The driver 200 may further include the transmitter 230 that may transmit the rotational energy as it is while lowering the rpm of the power generated from the rotation shaft 220.

[0980] The transmitter 230 may include the transmission pulley 232 that has the diameter larger than that of the rotation shaft 220 and rotates by being connected to the rotation shaft 220, and the transmission pulley 232 may have the power shaft 240 at the center of rotation thereof to rotate the power shaft 240 together with the rotation shaft 220.

[0981] The moving hanger 100 may further include the displacement generator 300 that converts the rotation of the rotation shaft 220 or the power shaft 240 in place into the displacement that may allow the reciprocating rotating part 500 to perform the reciprocating rotational motion.

[0982] In one example, the transmitter 230 may not be an essential component, and the rotation shaft 220 may be directly coupled to the displacement generator 300.

[0983] The displacement generator may include the eccentric shaft 310 that is coupled to the rotation shaft 220 or the power shaft 240 and rotates along a predetermined trajectory with a radius larger than the rotation radius of the rotation shaft 220 or the power shaft 240.

[0984] The eccentric shaft 310 may be disposed adjacent to the inner circumferential surface of the power shaft 240 by being spaced apart from the center of rotation of the power shaft 240, and may be coupled to a free end of an expansion shaft that is connected to and rotates together with the power shaft 240 and rotate with a radius much larger than the rotation radius of the power shaft 240.

[0985] The moving hanger 100 may include the support part 800 that supports at least one of the power transmitter 400, the driver 200, the displacement generator 300, and the reciprocating rotating part 500 on the inner casing 20.

[0986] The power transmitter 400 may be rotatably supported on the support part 800.

[0987] The power transmitter 400 may be rotatably supported on one of the support plate 810 and the auxiliary plate 880 or the seating plate 860 in the support part 800.

[0988] The power transmitter 400 may be rotatably supported by the support bearing 530 seated on the support plate 810.

[0989] The power transmitter 400 may include the support shaft 410 that passes through the support plate 810, is rotatably coupled to the support bearing 530, and forms the center of rotation of the power transmitter 400.

[0990] The power transmitter 400 may include the plurality of power transmitters spaced apart from each other by the predetermined distance along the length direction of the support plate 810.

[0991] The reciprocating rotating parts 500 may be respectively coupled to all of the power transmitters 400 or may be respectively extended from all of the power transmitters 400.

[0992] The moving hanger 100 may include the connector 600 that rotates the plurality of power transmitters 400 at one time or simultaneously.

[0993] The connector 600 may receive the power from the driver 200 and allow the plurality of power transmitters 400 to perform the reciprocating rotational motion at the same time and simultaneously within the same rotation angular range.

[0994] The connector 600 may connect the reciprocating rotating parts 500 to each other and may allow the plurality of power transmitters 400 to perform the reciprocating rotational motion.

[0995] The connector 600 may include a connector reciprocating body 650 coupled to the eccentric shaft 310 on the support plate 810.

[0996] The connector reciprocating body 650 may include a reciprocating body 651 having a length that may connect all of the plurality of power transmitters 400 or the plurality of reciprocating rotating parts 500 to each other, and a reciprocating body slit 652 that may extend through the reciprocating body 651 and may be connected to the eccentric shaft 310.

[0997] The reciprocating body slit 652 may be defined along a width direction of the reciprocating body 651, and a width of the reciprocating body slit 652 may be equal to or slightly larger than the diameter of the eccentric shaft 310. A length of the reciprocating body slit 652 defined along the width direction of the reciprocating body 651 may be equal to or greater than the rotation diameter of the eccentric shaft 310.

[0998] The reciprocating body 651 may extend along the direction in which the plurality of power transmitters 400 are arranged, and the reciprocating body slit 652 may be defined perpendicular to the direction in which the reciprocating body 651 extends.

[0999] The reciprocating rotating part 500 may further include a rotation induction shaft 550 that may be connected to the power transmitter 400 at a predetermined distance apart from the support shaft 410.

[1000] The rotation induction shaft 550 may extend through the support part 800 on the power transmitter 400, and may be disposed to be spaced apart from the support shaft 410 by a rotation distance.

[1001] The rotation induction shaft 550 may be disposed for each of the power transmitters 400, and may extend through the connector reciprocating body 650.

[1002] In one example, the power transmitter 400 may include the support shaft 410 and the auxiliary support part 420 that extends from the support shaft 410 and to which the hanger part 700 is coupled, similar to the embodiment described above.

[1003] The rotation induction shaft 550 may be coupled to or extended at a predetermined distance apart from the support shaft 410 above the auxiliary support part 420.

[1004] The support part 800 may also be equipped in the same manner as that in the embodiment described above. The connector reciprocating body 650 may be disposed upward of the support part 800 and perform the reciprocating rotational motion.

[1005] However, the support shaft 410 may extend through the support frame 810, but may be disposed downward of the connector reciprocating body 650. That is, the support shaft 410 does not extend through the connector reciprocating body 650.

[1006] The support shaft 410 may be rotatably supported by the support bearing 530 coupled to the shaft coupling portion 820 and be fixed to the support part 800.

[1007] However, the rotation induction shaft 550 may extend through both the support frame 810 and the connector reciprocating body 650. Accordingly, even when the rotation induction shaft 550 includes a plurality of rotation induction shafts, the plurality of rotation induction shafts may all be connected to the connector reciprocating body 650.

[1008] The distance between the support shaft 410 and the rotation induction shaft 550 may be set to be equal to or greater than the length of the reciprocating body slit 652.

[1009] The connector reciprocating body 650 may further include an arc slit 653 through which the rotation induction shaft 550 passes and that guides the movement direction or the rotation direction of the rotation induction shaft 550.

[1010] The rotation induction shaft 550 may be accommodated and disposed in the arc slit 653.

[1011] The arc slit 653 may be formed in an arc shape by being spaced apart by a rotation distance along a predetermined circumference of a rotational center point 654 corresponding to the support shaft 410.

[1012] The rotation distance may be set to be equal to the distance between the support shaft 410 and the rotation induction shaft 550.

[1013] The arc slit 653 may be defined at a location and an angle that may rotate the rotation induction shaft 550 when the reciprocating body 651 moves in the left and right direction.

[1014] For example, when the rotation induction shaft 550 is spaced apart from the support shaft 410 in the length direction of the support part 800, the arc slit 653 may be defined along the width direction of the support part 800.

[1015] When the rotation induction shaft 550 is spaced apart from the support shaft 410 in the width direction of the support part 800, the arc slit 653 may be defined along the length direction of the support part 800.

[1016] The arc slit 653 may be defined based on the rotational center point 654 over a certain angular range in which the rotation induction shaft 550 may perform the reciprocating rotational motion.

[1017] For example, the arc slit 653 may be formed in a semicircular shape.

[1018] In addition, the arc slit 653 may be formed in a semicircular arc shape such that both ends thereof form an arc with an angle greater than 90 degrees and equal to or smaller than 180 degrees based on the support shaft 410. A radius of the arc slit 653 may correspond to the rotation distance.

[1019] The support part 800 may further include the removal prevention step 890 that supports both side surfaces or a front / rear surface of the reciprocating body 651 so that the reciprocating body 651 may perform the reciprocating linear motion.

[1020] The removal prevention step 890 may protrude from the support frame 810 and fix one side surface of the reciprocating body 651.

[1021] In one example, although not shown, the support frame 810 may further include a movement slit having the same shape as the arc slit 653 at a location corresponding to the arc slit 653. The movement slit may be formed in an arc shape based on the shaft coupling portion 820. As a result, the rotation induction shaft 550 may move along the arc slit 653 without being restricted by the support frame 810.

[1022] FIG. 51 shows an operating scheme of a moving hanger 100.

[1023] Referring to (a) in FIG. 51, the power transmitters 400 may be arranged at the predetermined distance apart from each other along the width direction of the support part 800. The power transmitter 400 may be disposed at a correct location in the width direction, which is a point perpendicular to the length direction of the support part 800.

[1024] The rotation induction shaft 550 may be disposed in one of both ends of the arc slit 653.

[1025] The transmission pulley 232 may receive the power from the motor 210, and rotate the eccentric shaft 310 while rotating the power shaft 240.

[1026] The eccentric shaft 310 may be disposed at an exact center of the reciprocating body slit 652.

[1027] Referring to (b) in FIG. 51, the power shaft 240 may rotate in one direction to rotate the eccentric shaft 310.

[1028] The power shaft 240 may rotate at a certain angle to rotate the eccentric shaft 310, so that the eccentric shaft 310 may move inward from both ends of the reciprocating body slit 652.

[1029] When the reciprocating body 651 moves in one direction, the arc slit 653 also moves the reciprocating body 652 (No. 1).

[1030] As a result, the rotation induction shaft 550 may move to one of both ends of the arc slit 653 and may rotate the power transmitter 400 based on the rotational center point 654 (No. 2).

[1031] In addition, when the power shaft 240 rotates at the certain angle and thus the eccentric shaft 310 rotates to move toward both ends and then inward again, the reciprocating body 651 may move in an opposite direction, and the arc slit 653 may also move in an opposite direction.

[1032] As a result, the rotation induction shaft 550 may move to the other of both ends of the arc slit 653 and may rotate the power transmitter 400 in an opposite direction based on the rotational center point 654.

[1033] While repeating such process, the power transmitter 400 may perform the reciprocating rotational motion based on the angle formed by the arc slit 653 based on the rotational center point 654.

[1034] The eccentric shaft 310 may rotate in one direction to transmit the power of the driver 200 to the connector 600, and the connector 600 may perform the reciprocating rotational motion.

[1035] FIG. 52 shows minimum conditions for a power transmitter 400 to perform a reciprocating rotational motion.

[1036] A diameter of the rotation induction shaft 550 performing the reciprocating rotational motion with respect to the rotational center point 654 or a rotation distance L2, which is a separation distance between the arc slit 652 and the rotational center point 654, should be equal to or greater than a radius L1 of the eccentric shaft 310 rotating by the power shaft 240.

[1037] In this case, the eccentric shaft 310 may reciprocate the reciprocating body 651 in the left and right direction by repeatedly rotating once or more, and the rotation induction shaft 550 may reciprocate both ends of the arc slit 653 repeatedly.

[1038] As a result, the rotation induction shaft 550 may allow the power transmitter 400 to perform the reciprocating rotational motion, and the laundry or the clothes hanger 900 hung on the hanger part 700 may perform the reciprocating rotational motion in the left and right direction around the power transmitter 400.

[1039] The present disclosure may be modified and implemented in various forms, so that the scope of rights thereof is not limited to the above-described embodiments. Therefore, when the modified embodiment includes elements of the claims of the present disclosure, it should be considered to fall within the scope of the present disclosure.

[0168]FIG. 5 shows an outer appearance of a laundry treat...

TECHNICAL FIELD

[0001] The present disclosure relates to a laundry treating apparatus. More specifically, the present disclosure relates to a laundry treating apparatus that performs a refreshing cycle that may perform at least one of deodorization, wrinkle removal, and sterilization of laundry by supplying at least one of air and steam to the laundry.BACKGROUND

[0002] A laundry treating apparatus refers to an apparatus developed to wash and dry laundry and to remove wrinkles from the laundry at home and in a laundry shop. The laundry treating apparatus is a concept including a washing machine that washes the laundry, a dryer that dries the laundry, a washer / dryer that has both a washing function and a drying function, a laundry manager that refreshes the laundry, and a steamer that removes the wrinkles from the laundry.

[0003] Recently, a laundry treating apparatus corresponding to the laundry manager that allows the laundry to be kept pleasant and clean without having to soak the laundry in water and wash the laundry with detergent has appeared.

[0004] A laundry treating apparatus that performs a refreshing cycle of deodorizing the laundry, drying the laundry, and removing the wrinkles from the laundry by supplying one of high-temperature air and steam to the laundry has appeared.

[0005] The laundry treating apparatus that may perform the refreshing cycle may be equipped to oscillate the laundry while supplying hot air or steam to the laundry, to remove fine dust or foreign substances attached to the laundry. See Korean Patent No. 10-1285890.

[0006] FIG. 1 shows a structure of oscillating laundry in an existing laundry treating apparatus.

[0007] A moving hanger M of the existing laundry treating apparatus includes a support bar 2 disposed in an accommodating space where the laundry is hung, a hanger 3 that extends downward from the support bar 2 such that the laundry may be hung thereon, and a driver 5 that may oscillate the support bar 2.

[0008] The driver 5 may include a motor 51 fixed on the support bar 2 to rotate a rotation shaft 53, and may include an eccentric shaft 55 coupled to the rotation shaft 53 to rotate along a trajectory greater than a rotational diameter of the rotation shaft 53.

[0009] The support bar 2 may have a reciprocation inducer 4 installed at a center to accommodate the eccentric shaft therein and receive power. The eccentric shaft 55 may move along the rotation of the rotation shaft 53 while coupled to the reciprocation inducer 4 and reciprocate the reciprocation inducer 4 in a left and right direction.

[0010] The eccentric shaft 55 may rotate by being coupled to a distal end of a connecting shaft 52 coupled to a distal end of the rotation shaft 53.

[0011] FIG. 2 shows a structure in which a support bar moves in a left and right direction.

[0012] The reciprocation inducer 4 may include a slit 41 defined in a thickness direction of the support bar 2 and accommodating the eccentric shaft 55 therein.

[0013] FIG. 2 shows a structure in which a support bar moves in a left and right direction.

[0014] The reciprocation inducer 4 may include a slit 41 defined in a thickness direction of the support bar 2 and accommodating the eccentric shaft 55 therein.

[0015] Referring to (a) in FIG. 2, the eccentric shaft 55 may be inserted into the slit 41 and rotate along an arc trajectory with a radius of a distance R from the rotation shaft 53.

[0016] The support bar 2 may be fixed so as to be able to move only in the left and right direction in the laundry treating apparatus and not to move forward or rearward.

[0017] Referring to (b) in FIG. 2, when the eccentric shaft 55 rotates 90 degrees to the right, the slit 41 may move by R to the right together with the eccentric shaft 55 as the eccentric shaft 55 moves by R to the right. As a result, the support bar 2 moves to the right.

[0018] In such manner, when the eccentric shaft 55 rotates 180 degrees to the left, the slit 41 will move to the left, and the support bar 2 will also move to the left.

[0019] When the rotation shaft 53 rotates once, the support bar 2 may reciprocate in the left and right direction once, and when the rotation shaft 53 rotates continuously, the support bar 2 may reciprocate in the left and right direction several times.

[0020] As a result, the laundry hung on the hanger 3 extended from the support bar 2 may be oscillated in the left and right direction, so that the foreign substances or the dust may be removed.

[0021] However, because the support bar 2 reciprocates in the left and right direction, such existing laundry treating apparatus has a problem that the entire laundry treating apparatus vibrates strongly because of a rapid inertial force applied whenever the support bar 2 changes a movement direction thereof.

[0022] In particular, the more or heavier the laundry hung on the hanger 3, the greater the vibration, so that stability of the laundry treating apparatus is not able to be guaranteed.

[0023] In addition, the existing laundry treating apparatus has a problem that the greater the vibration, the louder the noise generated, the noise is emitted whenever the laundry treating apparatus is operated, and a use of the laundry treating apparatus is restricted at night.

[0024] FIG. 3 shows a state in which a driver output of an existing laundry treating apparatus is lost.

[0025] In addition, the existing laundry treating apparatus has a problem in that even when the driver 5 is able to provide sufficient output, the vibration generated by the reciprocating motion of the support bar 2 exceeds a reference value, so that a maximum output of the driver 5 is not able to be utilized.

[0026] In addition, there is a problem that the moving hanger in the left-right reciprocating motion scheme, like the existing laundry treating apparatus, is not able to fully receive a rotational power of a driving force of the driver 5.

[0027] Specifically, the slit 41 of the support bar 2 of the moving hanger is able to transmit power of the eccentric shaft 55 of rotating left or right to the laundry, but is not able to transmit power of the eccentric shaft 55 rotating rearward or forward to the laundry at all and causes the power to be lost.

[0028] Specifically, when the eccentric shaft 55 is disposed at locations I and III, the slit 41 may directly receive power of moving right and left.

[0029] However, when moving from the location I to a location II and when moving from the location III to a location IV, the power transmitted by the eccentric shaft 55 to move the slit 41 in the left and right direction is drastically reduced.

[0030] This is because the force of moving the slit 41 by the eccentric shaft 55 corresponds only to a cosine value of a rotation direction of the eccentric shaft 55, and therefore, when the eccentric shaft 55 is at 90 degrees and 270 degrees with respect to a center of rotation, the power transmitted from the eccentric shaft 55 to the slit 41 corresponds to 0.

[0031] In other words, the driver 5 continuously transmits the power to the eccentric shaft 55, but the eccentric shaft 55 is only able to transmit a portion of the power to the slit 41, and is not able to transmit an entirety of the power at a certain point.

[0032] As a result, a significant portion of the power of the driver 5 is lost without being transmitted to the laundry in the existing laundry treating apparatus. Therefore, the existing laundry treating apparatus has a problem that sufficient oscillating force is not transmitted to the laundry even though the driver 3 has sufficient output to oscillate the laundry, or that the driver 3s has to be operated with excessive output to transmit the sufficient oscillating force to the laundry.

[0033] As a result, the existing laundry treating apparatus has a fundamental problem that a performance of removing the foreign substances or the dust attached to the laundry is not excellent because the sufficient oscillating force is not transmitted to the laundry from the driver 3.

[0034] In addition, the existing laundry treating apparatus has a problem that the rotational power generated from the driver 3 is not able to be directly transmitted to the support bar 2 because the support bar 2 is disposed in a width direction and the hanger 3 is also fixed to the support bar 2.

[0035] To solve such problem, a laundry treating apparatus that may shake the hanger 3 on which the laundry is hung in a reciprocating rotational motion rather than in a linear reciprocating motion has appeared (See Chinese Patent Application Publication No. 111759148).

[0036] FIG. 4 shows a rotation structure of a hanger in an existing known technology.

[0037] The hanger 3 is rotatably mounted on the support bar 2, and a link 5 that is seated on the hanger 3 and is able to reciprocate in the left and right direction is disposed.

[0038] The reciprocation inducer 4 may be coupled to an outer circumferential surface of the hanger 3 via a fastening member 6.

[0039] A portion of the fastening member 6 coupled to the hanger 3 may be disposed to be spaced apart from a center of rotation of the hanger 3.

[0040] The reciprocation inducer 4 may be equipped as a bar-shaped link. When the reciprocation inducer 4 reciprocates in the left and right direction in a width direction, the fastening member 6 may reciprocate the reciprocation inducer 4.

[0041] As a result, the hanger 3 may perform the reciprocating rotational motion in the left and right direction, and the laundry hung on the above hanger 3 may also perform the reciprocating rotational motion.

[0042] However, in the prior art, when the link 5 performs the reciprocating rotational motion, the reciprocation inducer 4 should move forward and rearward to some extent based on a rotational trajectory of the hanger 3. As a result, the left-right reciprocating motion of the reciprocation inducer 4 is not able to be a perfect left-right reciprocating motion.

[0043] In one example, when the hanger 3 includes a plurality of hangers arranged to be spaced apart from each other and one reciprocation inducer 4 reciprocates by the driver 3, it may seem that the plurality of hangers 3 are able to perform the reciprocating rotational motion.

[0044] However, for the plurality of hangers 3 to perform the reciprocating rotational motion, the reciprocation inducer 4 coupled with the plurality of hangers 3 should move forward or rearward to correspond to a rotational trajectory of each of the plurality of hangers 3. However, because one end of the reciprocation inducer 4 is fixed to a distal end 51 of the driver 3, the reciprocation inducer 4 is not able to entirely move in a front and rear direction equally to the rotational trajectories of the plurality of hangers 3.

[0045] That is, the reciprocation inducer 4 moves forward or rearward at a certain angle centered on the one end coupled with the driver 3. In other words, the reciprocation inducer 4 has a larger amplitude at the other end, which is farther away from the driver 3, than at the one end.

[0046] Therefore, when the plurality of hangers 3 are arranged in parallel with each other along the width direction of the support bar 2, it is theoretically impossible to rotate all of the plurality of hangers 3 with the reciprocation inducer 4.

[0047] Therefore, the reciprocation inducer 4 is not able to rotate the plurality of hangers 5 simultaneously or at the same time.

[0048] As a result, the prior art has a fundamental problem that, when there are the plurality of hangers 3, the plurality of hangers 3 are not able to perform the reciprocating rotational motion simultaneously or at the same time.SUMMARYTechnical Problem

[0167] Hereinafter, embodiments disclosed herein will be described in detail with reference to the attached drawings. In the present document, identical or similar components are assigned identical or similar reference numerals even in different embodiments, and descriptions thereof are replaced with the first description. A singular expression used herein includes a plural expression unless the context clearly indicates otherwise. In addition, when describing the embodiments disclosed herein, when it is determined that a detailed description of a related known technology may obscure the gist of the embodiments disclosed herein, the detailed description thereof will be omitted. In addition, it should be noted that the attached drawings are only intended to facilitate easy understanding of the embodiments disclosed herein, and the technical ideas disclosed herein should not be construed as being limited by the attached drawings.

[0168] FIG. 5 shows an outer appearance of a laundry treating apparatus 1 of the present disclosure.

[0169] Referring to (a) in FIG. 5, the laundry treating apparatus of the present disclosure may include a cabinet 10 forming the outer appearance thereof, and a door 11 pivotably coupled to the cabinet 10.

[0170] Referring to (b) in FIG. 5, an inner casing 20 having an accommodating space 21 for accommodating laundry may be disposed inside the cabinet 10. The inner casing 20 may have an opening in a front surface thereof through which the laundry enters and exits, and the opening may be shielded by the door 11.

[0171] The inner casing 20 may be made of a plastic resin-based material, and may be made of a reinforced plastic resin-based material that does not deform even when exposed to air at a temperature higher than a room temperature or heated air (hereinafter, hot air), steam, or moisture.

[0172] The inner casing 20 may have a height greater than a width. Accordingly, the laundry may be accommodated in the accommodating space 21 without being folded or crumpled.

[0173] The laundry treating apparatus 1 of the present disclosure may include a clothes hanger 900 that may hang the laundry in the accommodating space 21 of the inner casing 20.

[0174] The clothes hanger 900 may be disposed on a top surface of the inner casing 20 and may be seated on a hanger part 700 for hanging the laundry. The clothes hanger 900 may be detachable from the hanger part 700.

[0175] When the laundry is hung on the hanger part 700, the laundry may be disposed in a state of floating in air within the accommodating space 21.

[0176] The laundry treating apparatus of the present disclosure may further include a pressurizer 50 that is coupled to an inner surface of the door 11 and is able to fix the laundry.

[0177] The pressurizer 50 may include a pressurizing surface 522 that is disposed on the inner surface of the door 11 and a pressurizing panel 521 that is pivotably coupled to the pressurizing surface 522 and is able to pressurize the laundry disposed on the pressurizing surface 522. The pressurizer 50 may mainly pressurize long laundry, such as bottoms, to remove wrinkles and create intended creases.

[0178] The laundry treating apparatus of the present disclosure may include a machine room 30 in which various apparatuses that may supply at least one of hot air and steam to the accommodating space 21 or purify or dehumidify outside air of the cabinet 10 are installed.

[0179] The machine room 30 may be disposed to be separated or partitioned from the inner casing 20, but may be in communication with the inner casing 20.

[0180] The machine room 30 may be disposed under the inner casing 20. Accordingly, when hot air and steam having low specific gravities are supplied to the inner casing 20, the hot air and the steam may be naturally supplied to the laundry.

[0181] The machine room 30 may include a circulation duct that circulates air inside the inner casing 20, and a plurality of heat exchangers disposed on the circulation duct to cool and condense the air and heat the air.

[0182] The machine room 30 may be equipped with a heat pump system including a compressor that is connected to the plurality of heat exchangers and is able to compress a refrigerant that cools or heats the air.

[0183] In one example, the machine room 30 may also be equipped with a steam supply that may supply steam into the inner casing 20.

[0184] The steam supply may heat water to generate the steam. Accordingly, the laundry accommodated inside the inner casing may be exposed to hot air and steam, so that deodorization, sterilization, and wrinkle removal may be performed.

[0185] In a front portion of the machine room 30, a water tank 31 that supplies water that generates the steam, and a drain tank 32 that collects condensed water in the circulation duct may be included.

[0186] The water tank 31 and the drain tank 32 may be detachably installed in the front portion of the machine room 30. Accordingly, even when the laundry treating apparatus of the present disclosure is not disposed near a water source or a drain hole, a user may detach and carry the water tank 31 and the drain tank 32 whenever necessary.

[0187] The water tank 31 and the drain tank 32 may be arranged in parallel with each other along a width direction of the machine room 30.

[0188] In addition, the machine room 30 may further include a drawer 33 that accommodates therein items or the like necessary for managing the laundry. The drawer 33 may be extendable from the machine room 30, and may have a space for accommodating the items such as an iron therein.

[0189] A seating stand 60 on which a separate shelf may be seated may be disposed inside the inner casing 20. The seating stands 60 may protrude at the same vertical level on both side surfaces of the inner casing 20.

[0190] The seating stand 60 may include a light emitter that irradiates light into the inner casing 20, and the light emitter may irradiate light toward the inner side surface of the inner casing 20 to prevent glare.

[0191] In one example, the laundry treating apparatus of the present disclosure may further include a moving hanger 100 that shakes the clothes hanger 900 to remove foreign substances and dust from the laundry hung on the clothes hanger 900.

[0192] The moving hanger 100 may operate when at least one of hot air and steam is supplied to the laundry, thereby inducing the foreign substances attached to the laundry to be removed by hot air or steam.

[0193] The moving hanger 100 may reciprocate and oscillate the clothes hanger 900.

[0194] FIG. 6 shows an upper structure of an inner casing.

[0195] The moving hanger 100 of the laundry treating apparatus of the present disclosure may include a power transmitter 400 disposed in an upper portion of the inner casing 10 to shake the clothes hanger 900.

[0196] The hanger part 700 on which the clothes hanger 900 may be seated or mounted may be disposed at a lower portion of the power transmitter 40.

[0197] Accordingly, when the power transmitter 40 moves, the hanger part 700 moves, and the clothes hanger 900 mounted on the hanger part 700 shakes, so that an effect of the laundry being shaken may be produced.

[0198] The power transmitter 400 may include a plurality of power transmitters, and the hanger part 700 coupled to the power transmitter 400 may also include a plurality of hangers. As a result, a large amount of laundry corresponding to the number of power transmitters 400 may be hung inside the inner casing 20 and refreshed.

[0199] The moving hanger 100 may further include a driver 200 that provides power to move the power transmitter 400.

[0200] When the driver 200 may be exposed into the inner casing 20 as long as it is able to transmit the power to the power transmitter 400. However, because the driver 200 operates by receiving electric energy, it is preferable that exposure to steam or hot air is blocked.

[0201] Accordingly, the driver 200 may be disposed between a top surface of the inner casing 20 and the cabinet 10 so as to be blocked from being exposed to the accommodating space 21.

[0202] The power transmitter 400 may receive the power from the driver 200 through the inner casing 20 and transmit the power to the hanger part 700.

[0203] The power transmitter 400 may extend through the top surface of the inner casing 20 and extend into the accommodating space 21. A lower end of the power transmitter 400 may be exposed to the accommodating space 21, and an upper end of the power transmitter 400 may be exposed to a portion above the inner casing 20.

[0204] The inner casing 200 or a support part 800 may further include a sealing member that may seal an area through which the power transmitter 400 extends. The sealing member may include a support bearing or the like, which is coupled to a hole in the inner casing 200 and the support part 800 that allows the power transmitter 400 to extend therethrough and rotatably supports the power transmitter 400.

[0205] As a result, air and steam supplied into the inner casing 200 may be blocked from leaking to a space above the top surface of the inner casing 200 or above the support member 800.

[0206] As a result, the driver 200 that is seated on the support part 800 may be stably operated without problems such as leakage, short circuit, or overheating.

[0207] The power transmitter 400 may be formed in a rod shape, a tube shape, or a plate shape, whose length is greater than a thickness.

[0208] In one example, the top surface of the inner casing 20 may support loads of the power transmitter 400 and the driver 200. The power transmitter 400 may move with the laundry hung thereon, and the load of the driver 200 may also be relatively great. Therefore, to stably install the moving hanger 100 on the top surface of the inner casing 20, the laundry treating apparatus 1 of the present disclosure may further include the support part 800.

[0209] The support part 800 may be disposed on the inner casing 20, but may be supported by being coupled to the cabinet 1. The support part 800 may be made of a metal material that is durable and difficult to deform.

[0210] The power transmitter 400 and the driver 200 may be seated on the support part 800 and disposed on the inner casing 20. The power transmitter 400 may extend through the support part 800 into the accommodating space 21.

[0211] In one example, the driver 200 includes a motor that rotates a rotation shaft. The driver 200 may move the power transmitter 400 with power that rotates the rotation shaft.

[0212] However, it may be difficult to shake the power transmitter 400 with a sufficient displacement by simply rotating the rotation shaft in place.

[0213] Therefore, the moving hanger 100 may further include a displacement generator 300 that is coupled to the rotation shaft rotated by the motor and generates the sufficient displacement to allow the power transmitter 400 to move.

[0214] The displacement generator 300 may be connected or coupled to the driver 200.

[0215] For example, the displacement generator 300 may transmit the power of the driver 200 to the power transmitter 400.

[0216] The displacement generator 300 may include an eccentric shaft that rotates along a trajectory greater than a diameter of the rotation shaft. The eccentric shaft may be directly coupled to the rotation shaft of the driver 200, but may be eccentrically coupled to or extended from a power shaft 240 that rotates by the rotation shaft.

[0217] The displacement generator 300 may be equipped as any component as long as it is able to generate a displacement that causes the power transmitter 400 to reciprocate within a certain range. A detailed structure thereof will be described later.

[0218] When the driver 200 operates, the power generated from the rotation shaft may generate the displacement of the displacement generator 300, and the power transmitter 400 may move based on the displacement of the displacement generator 300.

[0219] The displacement generator 300 may directly move the power transmitter 400, but may move the power transmitter 400 via an additional component.

[0220] The moving hanger 100 of the present disclosure may reciprocate the power transmitter 400.

[0221] In addition, the moving hanger 100 of the present disclosure may rotate the power transmitter 400. Specifically, the moving hanger 100 may allow the power transmitter 400 to perform the reciprocating rotational motion within a certain angular range, rather than reciprocate the power transmitter 400 in a straight line.

[0222] The power transmitter 400 may perform the reciprocating rotational motion clockwise or counterclockwise at a fixed location, and the laundry hung on the power transmitter 400 may also perform the reciprocating rotational motion clockwise or counterclockwise. The power transmitter 400 may rotate by the moving hanger 100, but may not move while varying the location thereof to the left or right.

[0223] Even when the laundry rotates by the power transmitter 400 inside the inner casing 20, a movement of a center of gravity thereof may be restricted inside the inner casing 20. Therefore, even when the moving hanger 100 operates, vibration occurring inside the inner casing 20 may be drastically reduced, and noise generation may also be minimized.

[0224] To this end, the moving hanger 100 may further include a reciprocating rotating part 500 that converts continuous rotational energy generated from the driver 200 or the displacement generator 300 into the reciprocating rotational motion of the power transmitter 400.

[0225] The reciprocating rotating part 500 may connect the displacement generator 300 with the power transmitter 400. The reciprocating rotating part 500 may connect the displacement generator 300 with the power transmitter 400 at a location above the inner casing 20. The reciprocating rotating part 500 may be prevented from being exposed to the accommodating space 21, thereby preventing the laundry from being damaged by the reciprocating rotating part 500.

[0226] In one example, the moving hanger 100 may allow only one of the plurality of power transmitters 400 to perform the reciprocating rotational motion.

[0227] However, when only one power transmitter 400 rotates, laundry hung on the rotating power transmitter may collide with laundry hung on another power transmitter 400 and be damaged. In addition, there is a concern that an impact may be transmitted to the moving hanger 100, thereby damaging the moving hanger 100.

[0228] Therefore, it is preferable that the moving hanger 100 rotates all of the plurality of power transmitters 400.

[0229] The moving hanger 100 may rotate the plurality of power transmitters 400 integrally. The plurality of moving hangers 400 may be rotated by the same angle simultaneously. Thus, the laundry treating apparatus of the present disclosure may prevent the power transmitters 400 from colliding with each other.

[0230] It may be advantageous in rotating all of the power transmitters 400 that the power generated by the driver 200 is directly transmitted to the plurality of power transmitters 400.

[0231] However, when the driver 200 is equipped to directly transmit the power to each of the power transmitters 400, a structure of connecting the driver 200 with all of the power transmitters 400 may become complicated.

[0232] In addition, when the driver 200 includes a plurality of drivers, or when there are a plurality of components that connect the driver 200 with all of the power transmitters 400, excessive load may be applied to the inner casing 20 or the support part 800. In addition, inconvenience of having to control the plurality of drivers 200 may also occur.

[0233] In addition, when the displacement generator 300 and the reciprocating rotating part 500 are connected to transmit the power transmitted from the single driver 200 to each of the power transmitters 400, an arrangement and structures of the displacement generator 300 and the reciprocating rotating part 500 may become complicated, which may lower reliability.

[0234] Therefore, the moving hanger 100 may be equipped such that the single driver 200 generates the power to rotate the plurality of power transmitters 400.

[0235] In addition, the moving hanger 100 may be equipped such that the power generated by the driver 200 may be preferentially transmitted to some of the power transmitters 400 or some of the reciprocating rotating parts 500, and then the power may be secondarily transmitted to the remaining power transmitters 400 or the remaining reciprocating rotating parts 500.

[0236] For example, the reciprocating rotating part 500 may receive the power transmitted from the driver 200 or the displacement generator 300 and transmit the power to some of the power transmitters 400. That is, the moving hanger 100 may be equipped such that the power generated by the driver 200 is intensively transmitted to the single reciprocating rotating part 500, thereby simply designing a power transmission structure and minimizing a power loss.

[0237] The moving hanger 100 of the present disclosure may transmit the power transmitted from the driver 200 to the single reciprocating rotating part 500, thereby rotating a specific power transmitter 400 connected to the reciprocating rotating part 500.

[0238] In addition, the moving hanger 100 may further include a connector 600 that transmits the power transmitted to the specific power transmitter 400 to another power transmitter 400.

[0239] For example, the connector 600 may connect the plurality of power transmitters 400 to each other. Accordingly, when one power transmitter 400 rotates, the connector 600 may rotate all of the plurality of power transmitters 400.

[0240] FIG. 7 shows an operating scheme of a moving hanger of the present disclosure.

[0241] Referring to (a) in FIG. 7, the power transmitter 400 may rotate to the right by the reciprocating rotating part 500 when the driver 200 operates. In this regard, all of the power transmitters 400 connected to the connector 600 may also rotate to the right.

[0242] Referring to (b) inFIG. 7, the power transmitter 400 may rotate to the left by the reciprocating rotating part 500 when the driver 200 further operates. In this regard, all of the power transmitters 400 connected to the connector 600 may also rotate to the left.

[0243] As such process is repeated, the power transmitter 400 may rotate in the left and right direction.

[0244] In this regard, the power transmitter 400 may rotate in the left and right direction while being fixed at a fixed location. The power transmitter 400 may be fixed to the support part 800 such that there is no change in location in a front and rear direction and the left and right direction when rotating.

[0245] The power transmitter 400 may be fixed such that the location thereof does not move based on a vertical direction, the front and rear direction, and a width direction.

[0246] However, the power transmitter 400 may rotate in the left and right direction using the vertical direction or a height direction in which the power transmitter extends as a rotation shaft. As a result, when the driver 200 operates, the hanger part 700 may perform the reciprocating rotational motion in the left and right direction around the power transmitter 400, and there may be no location movement.

[0247] Referring to (c) in FIG. 7, the clothes hanger 900 may include a ring 910 hung on the hanger part 700 and a seating portion 900 coupled to the ring 910. A surface-modified portion 950 that prevents the laundry from slipping may be disposed on a surface of the seating portion 950.

[0248] The seating portion 950 may be bilaterally symmetric around the ring 910. The clothes hanger 900 may be hung on the hanger part 700 such that the seating portion 950 is disposed in the front and rear direction.

[0249] When the power transmitter 400 rotates to the left, in the clothes hanger 900, a left side of the seating portion 950 based on the ring 910 may rotate to the left, and a right side of the seating portion 950 may rotate to the right. In this regard, an angle I at which the left side of the seating portion 950 rotates may be equal to an angle (theta) at which the right side of the seating portion 950 rotates, and a distance at which the left side of the seating portion 950 moves may be equal to a distance at which the right side of the seating portion 950 moves.

[0250] As a result, a weight and a force moving to the left and a weight and a force moving to the right may be equal to each other based on the clothes hanger 900, and thus may be offset from each other.

[0251] Similarly, even when the power transmitter 400 rotates to the right, as a result, the weight and the force moving to the left and the weight and the force moving to the right may be equal to each other based on the clothes hanger 900, and thus may be offset from each other.

[0252] As a result, even when the power transmitter 400 rotates, the forces applied to the clothes hanger 900 may be offset from each other, and as a result, a vibration force or an oscillating force, or an inertial force generated from the clothes hanger 900 itself may be minimized. As a result, inertial forces or the like generated from the plurality of power transmitters 400 may be minimized, and thus vibration or noise generated from the entire moving hanger 100 may be minimized, and vibration or noise generated from the entire laundry treating apparatus 1 may be drastically reduced.

[0253] As a result, even when the driver 200 rotates at the maximum output, the vibration generated from the moving hanger 100 or the entire laundry treating apparatus 1 may not be significantly generated.

[0254] Instead, because a surface of each laundry hung on the clothes hanger 900 rotates in the left and right direction to shake off dust, a dust shaking power may be greatly secured.

[0255] As described above, the power transmitter 400 may extend through the inner casing 20 to receive the power and perform the reciprocating rotational motion clockwise and counterclockwise. As a result, the power transmitter 400 may perform the reciprocating rotational motion in the left and right direction while the location thereof is fixed on the inner casing 20. The power transmitter 400 is fixed such that the location thereof does not change in the vertical direction and the left and right direction. In addition, not only an upper portion, but also a lower portion of the power transmitter 400 is fixed such that the location thereof does not change in the vertical direction and the left and right direction.

[0256] That is, the power transmitter 400 may perform a partial reciprocating rotational motion by a certain angle without completing a full revolution while a center of rotation thereof is fixed.

[0257] As a result, no matter how fast the power transmitter 400 rotates, the clothes hanger 900 is fixed in location and one end thereof rotates or moves to one side and the other end thereof rotates or moves to the other side, so that forces and vibrations transmitted to the power transmitter 400 may be offset from each other.

[0258] Therefore, the vibration and the noise generated by the power transmitter 400, the hanger part 700, and the clothes hanger 900 inside the inner casing 20 may be minimized.

[0259] As a result, the laundry treating apparatus of the present disclosure may rotate the driver 200 at a higher rpm to reciprocate the power transmitter 400 at a higher frequency. As a result, the laundry treating apparatus of the present disclosure may shake the laundry more strongly.

[0260] For example, the existing moving hanger M in the left-right reciprocating motion scheme and the moving hanger 100 of the present disclosure may be equipped with the driver 200 that exhibits the same output.

[0261] The existing moving hanger M has a limitation that the driver 200 is not able to operate at an rpm equal to or higher than a certain rpm. When the driver 200 operates at the rpm equal to or higher than the certain rpm, vibration generated from the laundry may exceed a limit value, and the vibration may damage the existing moving hanger M or generate excessive vibration or noise in the laundry treating apparatus.

[0262] However, in the moving hanger 100 of the present disclosure, the power transmitter 400 performs the reciprocating rotational motion clockwise or counterclockwise in place. Therefore, as described above, no matter how fast the clothes hanger 900 rotates, the vibrations or the inertial forces generated from the clothes hanger 900 and the laundry may be offset from each other when transmitted to the power transmitter 400.

[0263] As a result, even when the moving hanger 100 of the present disclosure increases the rpm of the driver 200 to the certain rpm or higher, the moving hanger 100 may not be damaged, and the generation of the vibration or the noise exceeding the limit value in the laundry treating apparatus may be blocked.

[0264] Therefore, the laundry treating apparatus of the present disclosure may operate the driver 200 faster than the laundry treating apparatus using the existing moving hanger, and may operate the power transmitter 400 at the higher frequency to shake the laundry more strongly.

[0265] Therefore, the laundry treating apparatus of the present disclosure may remove the foreign substances on the laundry more reliably via the moving hanger 100, and may remove the wrinkles from the laundry more effectively.

[0266] In addition, the laundry treating apparatus of the present disclosure may oscillate the laundry faster and more expose the laundry to supplied steam.

[0267] In addition, the laundry treating apparatus of the present disclosure may freely adjust the rpm of the driver 200 to adjust the operating frequency or an operating cycle of the power transmitter 400 based on a course.

[0268] FIG. 8 shows an embodiment of a moving hanger 100 of the present disclosure.

[0269] The moving hanger 100 of the present disclosure may transmit the power of the driver 200 to only one of the plurality of power transmitters 400, and transmit the power transmitted to the specific power transmitter 400 to the remaining power transmitters 400 via the connector 600.

[0270] The displacement generator 300 or the reciprocating rotating part 500 may intensively transmit the power generated by the single driver 200 to the single power transmitter 400. The connector 600 may transmit the power transmitted to the specific power transmitter 400 to all of the power transmitters 400.

[0271] The connector 600 may be equipped as a rigid body such that a length thereof does not vary, and may connect all of the power transmitters 400 to each other.

[0272] Accordingly, all of the power transmitters 400 may simultaneously rotate in the same direction and by the same angle when the connector 600 moves. As a result, the moving hanger 100 of the present disclosure may allow the plurality of power transmitters 400 to perform the reciprocating rotational motion simultaneously or at the same time by the same angle with the single driver 200.

[0273] The moving hanger 100 may include the driver 200 that is fixed on the inner casing 20 and provides the power for moving the power transmitter, the plurality of reciprocating rotating parts 500 that are respectively coupled to the plurality of power transmitters 400 and receive the power from the driver 200 to rotate such that a rotation direction thereof repeatedly changes, and the connector 600 that connects the plurality of reciprocating rotating parts to each other.

[0274] The connector 600 may include a link bar that connects the plurality of reciprocating rotating parts 500 to each other and rotates the plurality of reciprocating rotating parts 500 integrally.

[0275] The connector 600 may be equipped as a single unit.

[0276] The connector 600 may connect all of the power transmitters 400 to each other.

[0277] However, when the connector 600 connects the reciprocating rotating parts 500 to each other, the connector 600 may be installed upward of the support part 800, and thus, may be prevented from being exposed into the inner casing 20.

[0278] The connector 600 may be coupled to one of a front portion and a rear portion of the reciprocating rotating part 500, and at least one of the displacement generator 300 and the driver 200 may be disposed on the other of the front portion and the rear portion of the reciprocating rotating part 500. Therefore, the connector 600 may be prevented from interfering with the driver 200.

[0279] The connector 600 may reciprocate in the width direction of the inner casing 20 and rotate the plurality of reciprocating rotating parts 500.

[0280] The driver 200 may include a motor 210 that rotates a rotation shaft 210, the power shaft 240 that rotates together when the rotation shaft 210 rotates, and a transmitter 230 that connects the power shaft 240 with the rotation shaft 210 to transmit rotational power of the rotation shaft 210 to the power shaft 240.

[0281] The motor 210 may be fixed on the inner casing 20 and rotate the rotation shaft 220. However, the rotation shaft 220 is equipped to rotate too fast compared to an appropriate cycle for the motor 210 to allow the power transmitter 400 to perform the reciprocating rotational motion. When the rpm of the rotation shaft is lowered considering the above, there is a concern that the output of the motor 210 may not be transmitted to the power transmitter 400.

[0282] To solve such problem, the transmitter 230 may transmit the output of the rotation shaft 220 as it is to the power transmitter 400, but lower the rpm of the rotation shaft 220.

[0283] The transmitter 230 may rotate by being connected to the rotation shaft 220, but may rotate with a diameter larger than that of the rotation shaft 220. Accordingly, the transmitter 230 may transmit a torque of the rotation shaft 220 while rotating at an rpm lower than the rpm of the rotation shaft 220.

[0284] The power shaft 240 may rotate by the transmitter 230, may be formed separately from the rotation shaft 230, and may be a component that directly transmits the power to the power transmitter 400.

[0285] The reciprocating rotating part 500 may be coupled to the power transmitter 400 and may be rotatable together with the power transmitter 400.

[0286] The reciprocating rotating part 500 may include a reciprocating lever 510 coupled to the upper portion of the power transmitter 400 to rotate the power transmitter 400.

[0287] The reciprocating lever 510 may be formed in a rib or rod shape with a center of rotation coupled to a support shaft 410.

[0288] The reciprocating lever 510 may be coupled to an upper end of each of the plurality of power transmitters 400, and some of the reciprocating levers 510 may be connected to the transmitter 230 and receive the power from the motor 210.

[0289] The reciprocating lever 510 may perform the reciprocating rotational motion by a certain angle when the transmitter 230 is rotated by the motor 210. The power transmitter 400 may be coupled to the center of rotation of the reciprocating lever 510 and rotate together with the reciprocating lever 510.

[0290] The plurality of reciprocating levers 510 may be connected to each other via the connector 600.

[0291] The connector 600 may connect respective one ends of the plurality of reciprocating levers 510 to each other.

[0292] Accordingly, even when one of the plurality of reciprocating levers 510 rotates, the connector 600 may move and the plurality of reciprocating levers 510 may rotate simultaneously and at the same time.

[0293] The power transmitter 400 and the reciprocating lever 510 may be supported by the support part 800. In addition, the motor 210 and the transmitter 230 may also be supported by the support part 800.

[0294] FIG. 9 shows a moving hanger 100 of the present disclosure separated from an inner casing 20.

[0295] The power transmitter 400 may extend from above to below the inner casing, and the hanger part 700 may be coupled to the lower portion of the power transmitter 400.

[0296] Each reciprocating rotating part 500 may be coupled to each power transmitter 400, and may be easily connected to the driver 200 by being coupled to the upper portion of the power transmitter 400.

[0297] The power transmitter 400 and the reciprocating rotating part 500 respectively include the plurality of power transmitters and the plurality of reciprocating rotating parts arranged at a predetermined distance apart from each other along the width direction of the inner casing.

[0298] The connector 600 connects the plurality of power transmitters 400 or the plurality of reciprocating rotating parts 500 to each other. Thus, the connector 600 may simultaneously rotate the plurality of power transmitters 400 or the plurality of reciprocating rotating parts 500.

[0299] The power transmitter 400 may include the support shaft 410 that extends through an upper portion of the inner casing 20 and is coupled to the reciprocating lever 510.

[0300] The support shaft 410 may extend through the support part 800 and be exposed to a space above the support part 800 or above the inner casing 20.

[0301] The power transmitter 400 may include an auxiliary support part 420 coupled to the support shaft 410 and exposed to the accommodating space. The auxiliary support part 420 may be formed in a rod shape and the hanger part 700 may be coupled and fixed to a lower portion of the auxiliary support part 420.

[0302] The auxiliary support part 420 may be fixed to the support shaft 410 and rotate together with the support shaft 410. Accordingly, when the support shaft 410 is rotated by the reciprocating lever 510, the auxiliary support part 420 coupled to the support shaft 410 may also rotate, thereby allowing the hanger part 700 to rotate in the left and right direction.

[0303] The reciprocating levers 510 may include a main lever 511 that receives the power directly from the driver 200 and performs the reciprocating rotational motion, and an auxiliary lever 512 that receives the power from the main lever 511 via the connector 600.

[0304] The main lever 511 may be equipped as a single unit and may directly receive the power from the driver 200.

[0305] In the driver 200, the motor 210 may include a vertical motor 211 coupled to the support part 800, and a vertical rotation shaft 221 that rotates by the vertical motor 211.

[0306] The transmitter 230 may include a power pulley 231 that is coupled to the vertical rotation shaft 221 and rotates together with the vertical rotation shaft 221, a transmission pulley 232 that is coupled to the power shaft 240 and rotates the power shaft 240, and a belt 233 that connects portions of outer circumferential surfaces of the power pulley 231 and the transmission pulley 232 to each other.

[0307] The transmitter 230 may further include a pulley support 224 that rotatably supports the power shaft 240 and the transmission pulley 232. The pulley support 224 may support the transmission pulley 232 so as to be disposed in parallel with the power pulley 231, and may be seated on the support part 800.

[0308] The power shaft 240 may transmit the power transmitted from the rotation shaft 220 to one of two ends of the main lever 511.

[0309] The displacement generator 300 may be coupled to the power shaft 240 to receive the power. In addition, the displacement generator 300 may be connected to the main lever 511 to allow the main lever 511 to perform the reciprocating rotational motion around the support shaft 410.

[0310] For example, the displacement generator 300 may include an eccentric shaft that is eccentrically coupled to the power shaft 240 and rotates at a certain radius around a center of rotation of the power shaft 240.

[0311] The displacement generator 300 may be connected to a distal end of the main lever 511. The displacement generator 300 may allow the distal end of the main lever 511 to perform the reciprocating rotational motion around the support shaft 410 while being rotated by the power shaft 240.

[0312] The connector 600 may include a link bar 610 connecting one of the two ends of the main lever 511 that is not connected to the power shaft 240 or the displacement generator 300 with one end of the auxiliary lever 512.

[0313] The auxiliary levers 512 may be rotatably coupled to the remaining support shafts 410 that are not coupled to the main lever 511, and may extend in one direction from respective portions coupled to the support shafts 410 and be connected to the link bar 610.

[0314] The link bar 610 may be formed in a shape of a straight frame connecting one end of the main lever 511 with respective one ends of the auxiliary levers 512. In this regard, the one end of the main lever 511 and the respective one ends of the auxiliary levers 512 may be arranged parallel to each other based on the link bar 610 or the width direction.

[0315] The link bar 610 may be equipped as a single unit and may rotate the main lever 511 and the auxiliary levers 512 simultaneously and at the same time around their respective support shafts 410.

[0316] The inner casing 20 may include a through-hole 23 in which a portion of the support part 800 is seated to expose the power transmitter 400 to the accommodating space 22.

[0317] The through-hole 23 may be defined in the top surface 22 of the inner casing, and the through-hole 23 may be defined along the direction in which the power transmitters 400 are arranged.

[0318] For example, the power transmitters 400 may be arranged to be spaced apart from each other along the width direction of the inner casing, and the through-hole 23 may be defined along the width direction of the inner casing.

[0319] The laundry treating apparatus 1 of the present disclosure may further include a support frame 12 that is disposed outside the inner casing and supports the cabinet 1.

[0320] The support frame 12 may be disposed at a location corresponding to each corner of the cabinet 1 or each corner of the inner casing 20 and may be made of a metal material that maintains the outer appearance of the laundry treating apparatus. The support part 800 may have both ends seated and supported on the support frame 12, thereby preventing unnecessary impact or load from being transmitted to the top surface 22 of the inner casing.

[0321] FIG. 10 is an exploded perspective view of a moving hanger 100 of the present disclosure.

[0322] The power transmitter 400 may include the support shaft 410 that passes through the top surface of the inner casing 20 and is coupled to the reciprocating lever 510, the auxiliary support part 420 that is coupled to the support shaft 410 and is exposed to the accommodating space 21, and the hanger part 700 that is coupled to the auxiliary support part 420 and hangs the clothes hanger 900 or the laundry thereon.

[0323] The support shaft 410 may be formed in a cylindrical shape whose length is greater than a diameter, and thus, may be easily rotated by the reciprocating lever 510.

[0324] The support shaft 410 may have a diameter much smaller than that of the auxiliary support part 420, thereby extending through the inner casing or the support part 800 with a smaller area size. Therefore, a possibility of hot air or steam supplied to the accommodating space leaking upwardly of the inner casing 20 may be further reduced.

[0325] The auxiliary support part 420 may have a larger cross-sectional area than the support shaft 410 and may have a greater length than the support shaft 410. As a result, the auxiliary support part 420 may secure a rigidity and an area size to support and rotate the hanger part 700 and the clothes hanger 900.

[0326] The support part 800 may include a support plate 810 through which the support shaft 410 passes and on which the driver 200 may be supported. The support plate 810 may be equipped as a metal plate so that rigidity and durability may be guaranteed, and may extend in the direction in which the plurality of power transmitters 400 are arranged.

[0327] The support part 800 may include an extending body 812 extending upward from both ends of the support plate 810 to define a space in which the driver 200 and the reciprocating rotating part 500 are seated between the inner casing 20 and an upper portion of the cabinet 10, and a seating body 813 extending from the extending body 821 so as to be seated on the support frame 12.

[0328] The support part 800 may include a shaft coupling portion 820 through which the support shaft 410 may extend.

[0329] The shaft coupling portion 820 may include a plurality of shaft coupling portions so as to be arranged at locations corresponding to the locations where the power transmitters 400 are arranged, and may be arranged to be spaced apart from each other along a length direction of the support plate 810.

[0330] In one example, the support part 800 may further include an auxiliary plate 880 coupled to a lower portion of the support plate 810. The auxiliary plate 880 may be made of a resin-based material and may partially accommodate an outer circumferential surface of the power transmitter 400 therein.

[0331] The auxiliary plate 880 may include a plurality of accommodating holes 882 that may be defined below the support plate 810 and rotatably accommodate the respective power transmitters 400 therein, a plurality of extension steps 883 extending from the respective accommodating holes 882 with a greater width, and a fixed plate 881 that may extend from the extension steps 883 to face the support plate 810 and may be coupled and fixed to the support plate 810.

[0332] The accommodating hole 882 may be defined at an upper end of the support shaft 410 or the auxiliary support part 420 to prevent hot air or air from being discharged to the shaft coupling portion 820. The extension step 883 may serve to disperse a load or an impact transmitted to the auxiliary plate 880, and may serve to prevent collision or interference between the accommodating hole 882 and the clothes hanger 900.

[0333] The support part 800 may further include a seating plate 820 seated on the support plate 810.

[0334] The seating plate 820 may serve to support a bearing seated on the shaft coupling portion 820 and, at the same time, may serve to prevent the reciprocating lever 510 and the connector 600 from colliding with or rubbing against the support plate 810.

[0335] The seating plate 820 may include a seating board 861 seated on the support plate 810, and a seating hole 862 that passes through the seating board 861 and is defined in an area corresponding to the shaft coupling portion 820.

[0336] The reciprocating levers 510 may include the main lever 511 that directly receives the power from the driver 200, and the auxiliary levers 512 that receive the power from the main lever 511 via the connector 600.

[0337] The main lever 511 and the auxiliary levers 512 may be coupled to the respective support shafts 410 and rotate around the support shafts 410.

[0338] The link bar 610 may include a link body 611 that may be seated on the main lever 511 and the auxiliary levers 512 and may connect them to each other, and connecting hooks 612 that may protrude from the link body 611 and may be rotatably disposed on the main lever 511 and the auxiliary levers 512.

[0339] The reciprocating lever 510 may include link bearings 513 that are respectively coupled to the one end of the main lever 511 and the respective one ends of the auxiliary levers 512 and rotatably supports the respective connecting hooks 612.

[0340] When the link bar 610 rotates in the left and right direction, the main lever 511 or the auxiliary lever 512 may perform the reciprocating rotational motion in the left and right direction.

[0341] The reciprocating rotating part 500 may further include a support bearing 530 that may rotatably support the support shaft 410 or the reciprocating lever 510.

[0342] The support bearing 530 may rotatably accommodate the support shaft 410 therein and may be seated on the shaft coupling portion 620.

[0343] The reciprocating lever 510 may be disposed on an upper surface of the support bearing 530.

[0344] The support bearing 530 may be composed of a plurality of components stacked or may be equipped as a ball bearing or an oilless bearing.

[0345] The seating plate 860 may support the support bearing 530 and may block hot air or moisture from being exposed from an outer circumferential surface of the support bearing 530.

[0346] In addition, the auxiliary plate 880 may also be disposed under the support bearing 530 and block hot air or moisture from being exposed from the outer circumferential surface of the support bearing 530.

[0347] FIG. 11 shows an operating scheme of a moving hanger 100 of the present disclosure.

[0348] Referring to (a) in FIG. 11, the main lever 511 may include a main body 5111 coupled to the support shaft 410 and coupled to the link bar 610.

[0349] The main body 5111 may include a main center hole 5115 that may be coupled to the support shaft 410 and rotate the support shaft 410, and may extend from the main center hole 5115 to both sides.

[0350] The main body 5111 may include a main receiving hole 5112 that receives the power from the driver 200 at one end, and may include a main transmitting hole 5113 in which the link bar 610 is seated and coupled at the other end.

[0351] The main body 5111 may further include a stepped portion 5114 that extends from the center hole to the main receiving hole 5112, but forms a step. In the main body 5111, because of the stepped portion 5114, one end of the main body 5111 or the main transmitting hole 5113 may be positioned downward of the main center hole 5115.

[0352] Therefore, a length of the power shaft 240 or the eccentric shaft 310 positioned on the main center hole 5115 extending from the transmitter 230 may be secured.

[0353] In one example, the auxiliary lever 512 may include an auxiliary body 5121 having an auxiliary center hole 5125 coupled to the support shaft 410 and an auxiliary transmitting hole 5123 extending to one side from the auxiliary center hole 5125 and coupled to the link bar 610.

[0354] The auxiliary body 5121 may have a length smaller than that of the main body 5111.

[0355] A distance from the main center hole 5115 to the main transmitting hole 5113 may be set to be equal to a distance from the auxiliary center hole 5125 to the auxiliary transmitting hole 5123.

[0356] The link bar 610 may be seated on the auxiliary transmitting hole 5123 and the main transmitting hole 5113 to connect the auxiliary lever 512 with the main lever 511.

[0357] Referring to (b) in FIG. 11, the driver 200 may be equipped such that the power shaft 240 is inserted into the main receiving hole 5112. As a result, the power shaft 240 may be directly rotated to rotate the main receiving hole 5112 in the left and right direction.

[0358] In other words, the power shaft 240 may not generate enough displacement to rotate the main receiving hole 5112 in the left and right direction based on the main center hole 5115 by only rotating.

[0359] To this end, the displacement generator 300 may be coupled to the power shaft 240 to generate a displacement greater than a rotation radius of the power shaft 240.

[0360] The displacement generator 300 may convert the stationary rotational motion of the power shaft 240 into a reciprocating displacement motion within a certain range. The displacement motion may be transmitted to the reciprocating rotating part 500, so that the power transmitter 400 may perform the reciprocating rotational motion.

[0361] As described above, the displacement generator 300 may include an eccentric shaft 310 that is coupled to further extend from the power shaft 240 and rotates while drawing a trajectory along a certain radius.

[0362] The eccentric shaft 310 may have a diameter smaller than that of the power shaft 240, and may coupled to or extended from the power shaft 240 while being spaced a predetermined distance apart from a center of rotation of the power shaft 240.

[0363] Therefore, the eccentric shaft 310 may rotate in a circle with a radius of the distance separated from the power shaft 240 when the power shaft 240 rotates.

[0364] The diameter of the eccentric shaft 310 may be set smaller than a diameter or a width of the main receiving hole 5112. Thus, the eccentric shaft 310 may be inserted into and supported by the main receiving hole 5112.

[0365] However, the predetermined radius of rotation of the eccentric shaft 310 may be set greater than the width or the diameter of the main receiving hole 5112. As a result, when the eccentric shaft 310 rotates, the main receiving hole 5112 may be pushed by the eccentric shaft 310 and may move in the left and right direction based on the main center hole 5115.

[0366] As a result, when the eccentric shaft 310 rotates in a specific direction x, the main receiving hole 5112 of the main body 511 may also perform the reciprocating rotational motion along a certain direction y. As a result, the center hole 5115 of the main body may also rotate in the same direction as the main receiving hole 5112, and the main transmitting hole 5113 may perform the reciprocating rotational motion in a direction z opposite to the certain direction.

[0367] When the eccentric shaft 310 rotates, the support shaft 410 may perform the reciprocating rotational motion together with the main center hole 5115, so that the power transmitter 400 may perform the reciprocating rotational motion. Further, the main transmitting hole 5113 may also perform the reciprocating rotational motion to reciprocate the link bar 610, so that the auxiliary lever 521 may also perform the reciprocating rotational motion around the auxiliary center hole 5125 and the support shaft 410. The power transmitter 400 coupled to the auxiliary lever 521 may also perform the reciprocating rotational motion.

[0368] The power transmitter 400 may have a screw thread along a circumference of the upper portion of the support shaft 410.

[0369] The main transmitting hole 5113 and the auxiliary center hole 5125 may be directly coupled and fixed to the support shaft 410 using the screw thread or the like.

[0370] However, the power transmitter 400 may further include a transmitter coupling portion 415 that is coupled to the screw thread of the support shaft 410 so as to extend through the main transmitting hole 5113 and the auxiliary center hole 5125 and then fix the support shaft 410 to the main transmitting hole 5113 and the auxiliary center hole 5125.

[0371] Therefore, the support shaft 410 and the reciprocating lever 510 may be coupled to each other by the transmitter coupling portion 415, so that the support shaft 410 and the reciprocating lever 510 may rotate simultaneously.

[0372] FIG. 12 shows an operating process of a moving hanger 100 of the present disclosure.

[0373] Referring to (a) in FIG. 12, in the main lever 511, the main receiving hole 5112 may rotate to the left with respect to the main center hole 5115 by the rotation of the eccentric shaft 310 (No. 1).

[0374] When the main receiving hole 5112 rotates to the left, the main center hole 5115 may also rotate counterclockwise (No. 2). In this process, the power transmitter 400 coupled to the main center hole 5115 may rotate counterclockwise.

[0375] The main receiving hole 5113 rotates counterclockwise around the main center hole 5115. In this regard, the link bar 610 may move to the right as the main receiving hole 5113 moves (No. 3).

[0376] When the link bar 610 moves to the right, the auxiliary receiving hole 5123 in the auxiliary lever 512 rotates counterclockwise with respect to the auxiliary center hole 5125.

[0377] Because the link bar 610 is connected to the plurality of auxiliary levers 512, all the auxiliary levers 512 rotate counterclockwise (No. 4).

[0378] When the auxiliary lever 512 rotates counterclockwise, the power transmitter 400 coupled to the auxiliary center hole 5125 also rotates counterclockwise (No. 5).

[0379] Referring to (b) in FIG. 12, the main receiving hole 5112 in the main lever 511 may rotate to the right with respect to the main center hole 5115 by the rotation of the eccentric shaft 310 (No. 1).

[0380] When the main receiving hole 5112 rotates to the right, the main center hole 5115 may also rotate clockwise (No. 2). In this process, the power transmitter 400 coupled to the main center hole 5115 may rotate clockwise.

[0381] The main receiving hole 5113 rotates clockwise around the main center hole 5115. In this regard, the link bar 610 may move to the left as the main receiving hole 5113 moves (No. 3).

[0382] When the link bar 610 moves to the left, the auxiliary receiving hole 5123 in the auxiliary lever 512 rotates clockwise with respect to the auxiliary center hole 5125. Because the link bar 610 is connected to the plurality of auxiliary levers 512, all the auxiliary levers 512 rotate clockwise (No. 4).

[0383] When the auxiliary lever 512 rotates clockwise, the power transmitter 400 coupled to the auxiliary center hole 5125 also rotates clockwise (No. 5).

[0384] When this process is repeated, the main lever 511 may receive the power from the driver 200 and perform the reciprocating rotational motion clockwise and counterclockwise, thereby allowing the power transmitter 400 coupled to the main lever 511 to perform the reciprocating rotational motion and reciprocating the link bar 610 in the left and right direction.

[0385] The link bar 610 may allow the auxiliary lever 512 to perform the reciprocating rotational motion while reciprocating in the left and right direction, and may allow the power transmitter 400 coupled to the auxiliary lever 512 to perform the reciprocating rotational motion.

[0386] The link bar 610 is formed as the rigid body, and the auxiliary lever 512 and the main lever 511 are coupled to the link bar 610 at locations spaced apart from the respective support shafts 410 by the same length.

[0387] Therefore, because of the link bar 610, the auxiliary lever 512 and the main lever 511 may perform the reciprocating rotational motion by the same angle, and as a result, all the power transmitters 400 may rotate at the same angle simultaneously and at the same time, and angles of the reciprocating rotational motion thereof may also be the same.

[0388] The main lever 511 may be disposed between the auxiliary levers 512. In addition, the auxiliary levers 512 may be arranged symmetrically with respect to the main lever 511. As such, a load may be evenly applied to both sides of the link bar 610 connected to the main lever 511.

[0389] However, when the power of the main lever 511 is able to be transmitted to the auxiliary lever 512, the main lever 511 and the auxiliary levers 512 may be arranged in any arrangement or order.

[0390] FIG. 13 shows a power transmission structure of a moving hanger 100 of the present disclosure.

[0391] As described above, the power generated from the driver 200 may not be directly transmitted to all the reciprocating levers 510, but may be transmitted to the main lever 511, and the remaining auxiliary levers 512 may instead receive the power via the link bar 610.

[0392] The driver 200 may include the vertical motor 211 seated on the support part 800, and the rotation shaft 221 that rotates in the vertical motor 211.

[0393] The driver 200 may include the transmitter 230 that may transmit the torque as it is while lowering the rpm transmitted from the rotation shaft 221, and the transmitter 230 may include the power pulley 231 coupled to the rotation shaft 221, the transmission pulley 232 disposed adjacent to the main lever 511 on the power pulley 231, and the belt 233 connecting the power pulley with the transmission pulley.

[0394] The power shaft 240 that is coupled to the transmission pulley 232 and rotates is included.

[0395] The power shaft 240 may transmit the power to allow the main lever 511 to perform the reciprocating rotational motion, and the main lever 511 may allow the auxiliary lever 512 to perform the reciprocating rotational motion via the link bar 610.

[0396] The power transmitters 400 respectively coupled to the main lever 511 and the auxiliary levers 512 and supported by the support part 800 may perform the reciprocating rotational motion in place to allow the hangers 900 to perform the reciprocating rotational motion.

[0397] FIG. 14 shows a coupled structure of the driver and the displacement generator.

[0398] The transmission pulley 232 may be formed in a disk shape, and the power shaft 240 may be firmly coupled inside the transmission pulley 232.

[0399] The power shaft 240 may include a shaft body 241 coupled to the transmission pulley 232 and extending toward the main lever 511 and a shaft boss 242 coupled to an upper end of the shaft body 241 and fixed to the transmission pulley 232.

[0400] In one example, the transmitter 230 may include a pulley support 234 that is seated on the support part 800 to rotatably support the shaft body 241 and also support a load of the transmission pulley 232.

[0401] The pulley support 234 may be made of a metal material.

[0402] The displacement generator 300 may include the eccentric shaft 310 that may be inserted into the main receiving hole 5111 and rotate at a free end of the power shaft 240.

[0403] The eccentric shaft 310 may rotate along a trajectory having a diameter larger than the diameter of the power shaft 240.

[0404] The main body 511 may be fixedly coupled to the support shaft 410 that passes through the inner casing 20 or the support part 800. The main body 511 may have a center of rotation coupled to the support shaft 410 and one end accommodating the eccentric shaft 310 therein.

[0405] The power transmitter 400 may include the support shaft 410 and the auxiliary support part 420 that passes from the support shaft 410, and the auxiliary support part 420 may be coupled while accommodating a portion of the support shaft 410 therein.

[0406] The support part 800 may seat the support bearing 530, which rotatably supports the support shaft 410, on a top surface thereof, and the main body 511 may be coupled to an upper portion of the support bearing 530.

[0407] As a result, loads of the hanger part 700 and the clothes hanger 900 may be transmitted to the power transmitter 400, and the power transmitter 400 may support the loads of the hanger part 700 and the clothes hanger 900.

[0408] In the power transmitter 400, the support shaft 410 supports a load of the auxiliary support part 420. The support bearing 530 and the main lever 511 support a load of the support shaft 410. In one example, the support bearing 530 and the auxiliary lever 512 also support a load of the support shaft 410 coupled thereto.

[0409] Therefore, loads of the support bearing 530 and the reciprocating lever 510 are supported on the support part 800 via the support bearing 530. As a result, the support part 800 may support a load of the entire moving hanger 100 and be fixed to the cabinet 10.

[0410] FIG. 15 shows a structure of a main lever.

[0411] The main lever 511 may include the main body 5111 that extends to both sides from the main center hole 5115 coupled to the support shaft 410.

[0412] The main body 5111 has the main receiving hole 5112 in which the eccentric shaft 310 or the power shaft 240 is rotatably accommodated at one end thereof, and the main transmitting hole 5113 into which a hook coupling portion of the link bar 610 is coupled at the other end thereof.

[0413] Distances at which the main receiving hole 5112 and the main transmitting hole 5113 are spaced apart from the main center hole 5115 may be set to be equal to each other, but may be set to be different from each other.

[0414] The main body 5111 may transmit a greater torque to the main center hole 5115 and the main transmitting hole 5113 as a distance between the main receiving hole 5112 and the main center hole 5115 is set to be greater.

[0415] FIG. 16 is an exploded perspective view of a driver of a moving hanger 100 of the present disclosure.

[0416] The vertical motor 211 may include a motor fastening portion 214 coupled to the support part 800, and a sensor 213 that senses an operating state of the vertical motor 211 or an rpm state of the vertical motor and transmits the state to a controller.

[0417] The vertical rotation shaft 221 may be rotatably disposed at a center of the vertical motor 211.

[0418] The power pulley 231 may be coupled to one end of the vertical motor 211. The power pulley 231 may have a groove defined along an outer circumferential surface thereof, corresponding to a thickness or a width of the power belt 233.

[0419] The transmission pulley 232 may include a transmission body 2321 formed in a shape of a disk or a wheel with a diameter larger than that of the power pulley 231. A groove 2322 in which the belt 2333 may be seated may be defined in an outer circumferential surface of the transmission body 2321.

[0420] A plurality of reinforcing beads 2324 for maintaining rigidity may be disposed on both surfaces of the transmission body 2321. A through-coupling portion 2323 through which the power shaft 240 extends and is coupled may be defined at a center of the transmission body 2321. The reinforcing beads 2324 may extend radially from the through-coupling portion 2323.

[0421] The pulley support 234 may include a seating body 2341 that is seated on the support part 800, and a support body 2341 that ascends upwards in a stepped manner from a center of the seating body 2341 to support the load of the power shaft 240.

[0422] A pulley bolt 235 coupled to the support part 800 may extend through the seating body 2341 and be coupled to the seating body 2341.

[0423] A bearing support 2342 that supports the outer circumferential surface of the power shaft 240 may extend on the support body 2341, and a pulley bearing 2344 that rotatably supports the power shaft 240 may be seated inside the bearing support 2342.

[0424] The pulley support 234 may further include a cut groove 2345 defined by cutting one of the support body 2341, the seating body 2341, and the bearing support 2442 to guide the main lever 511 to be coupled to the eccentric shaft 310.

[0425] The power shaft 240 may include the shaft body 241 that is coupled to the transmitter 230 and rotates, and a first bearing 243 that is disposed around a lower portion of the shaft body 241 and is rotatably coupled to the pulley bearing 2344 or the bearing support 2342.

[0426] The power shaft 240 may further include a second bearing 244 coupled to the shaft body 241 by being spaced downwardly apart from the first bearing 243.

[0427] Between the first bearing 243 and the second bearing 244, a separation groove 245 defined along a circumference of the shaft body 241 may be defined.

[0428] Therefore, the first bearing 243 and the second bearing 244 may be rotatably coupled to the bearing support 2442 to support the shaft body 241 so as not to bend.

[0429] A ring-to-be-inserted that may be inserted into the separation groove 245 may be formed on an inner circumferential surface of the bearing support 2442. Because of the ring-to-be-inserted, an installation vertical level of the shaft body 241 may be maintained, and at the same time, a load of the transmission pulley 232 may also be transmitted to the pulley support 234.

[0430] The eccentric shaft 310 may include an eccentric shaft body 311 that extends from one side of the power shaft 240 and is accommodated in the main receiving hole 5112.

[0431] In this regard, an eccentric bearing 312 that is coupled to an outer circumferential surface of the eccentric shaft body 311 to expand a diameter of the eccentric shaft 310, extend an angle of the reciprocating rotational motion of the main lever 511, and reinforce rigidity of the eccentric shaft body 311 may be included.

[0432] The eccentric bearing 312 may be made of a material different from that of the eccentric shaft body 311.

[0433] The eccentric shaft 310 may further include a fixing clip 313 that fixes the eccentric bearing 312 and the eccentric shaft body 311.

[0434] The eccentric bearing 312 may rotate based on the eccentric shaft body 311, and may rotate by being in contact with the inner circumferential surface of the main receiving hole 5112.

[0435] Therefore, even when the eccentric shaft 310 rotates at a high rpm, a frictional force between the eccentric shaft 310 and the main receiving hole 5112 may be minimized.

[0436] FIG. 17 shows a connection structure of a driver and a reciprocable portion of the moving hanger 100 of the present disclosure.

[0437] The power transmitter 400 may be coupled to the reciprocating rotating part 500 and perform the reciprocating rotational motion.

[0438] At least one of the power shaft 240 and the eccentric shaft 310 may be disposed parallel to the power transmitter 400.

[0439] The support body 420 may perform the reciprocating rotational motion in the left and right direction with respect to the support shaft 410.

[0440] The power transmitter 400 may be merely equipped to perform the reciprocating rotational motion clockwise and counterclockwise with respect to the support shaft 410, and the location thereof may not vary in a radial direction or the like.

[0441] The support shaft 410 may allow the support body 420 to perform the reciprocating rotational motion while the vertical location thereof is completely fixed via the support bearing 530.

[0442] The support body 420 may rotate while changing a rotation direction thereof with respect to the support shaft 410.

[0443] In one example, the power transmitter 400 also supports the loads of the hanger part 700, the clothes hanger 900, and the laundry in the inner casing 200 or transfers the loads to the support part 800.

[0444] The support frame 810 may support the load of the hanger by supporting the load of the power transmitter 400.

[0445] The support part 800 may further place the auxiliary plate 880 under the support frame 810.

[0446] The auxiliary plate 880 may include an auxiliary body 881 disposed under the support frame 810, and an auxiliary through-hole 882 that extends through the auxiliary body 881 and allows the support shaft 410 or the like to extend therethrough.

[0447] The support bearing 530 is coupled to the shaft coupling portion 820 of the support 820 to rotatably support the support shaft 410 and seal the outer circumferential surface of the support shaft 410. In addition, the support bearing 530 also seals an inner circumferential surface of the shaft coupling portion 820.

[0448] The auxiliary through-hole 882 may further extend upward of the auxiliary body 881 along a height direction of the support shaft 410. In other words, the auxiliary through-hole 882 may not be defined as a simple hole, but may be formed in a cylindrical shape that extends upward to have a certain height and accommodates at least a portion of the support shaft 410 therein.

[0449] In addition, the auxiliary plate 880 may include a blocking wall 885 that extends away from the auxiliary through-hole 882 such that the auxiliary through-hole 882 may be accommodated inside the auxiliary body 881.

[0450] The blocking wall 885 may also be formed in a cylindrical shape, and may have a diameter that allows the auxiliary through-hole 882 and the support shaft 410 to be disposed inside the blocking wall.

[0451] The blocking wall 885 may have a height so as to overlap at least a portion of the support bearing 530, and may have a diameter so as to accommodate at least a portion of the support bearing 530 therein.

[0452] The blocking wall 885 may be disposed at a predetermined distance from an outer circumferential surface of the shaft coupling portion 820 or an outer circumferential surface of the support bearing 530.

[0453] As a result, the auxiliary plate 880 may increase a flow resistance between the outer circumferential surface of the support shaft 410 and the auxiliary through-hole 882, and may increase a flow resistance between the shaft coupling portion 820 and the auxiliary body 881.

[0454] As a result, steam and hot air supplied into the inner casing 200 may be blocked to the maximum extent from flowing through the auxiliary through-hole 882 and the shaft coupling portion 820 toward the support bearing 530.

[0455] A detailed structure of the auxiliary plate 880 will be described later.

[0456] FIG. 18 shows a coupling structure of components.

[0457] (a) in FIG. 18 shows a coupling structure of the connector 600 and the reciprocating lever 510. The reciprocating lever 510 may further include a link bearing 513 coupled to the main transmitting hole 5113 or the auxiliary transmitting hole 5123 to rotatably support the connecting hook 612.

[0458] The link bearing 513 may be made of a material different from that of the reciprocating lever 510, may be made of a self-lubricating material, or may be equipped as a general bearing.

[0459] A distal end of the connecting hook 612 may be formed in a wedge shape or an arrowhead shape that enables easy insertion into the link bearing 513, the main transmitting hole 5113, or the auxiliary transmitting hole 5123, while preventing easy removal.

[0460] The connecting hook 612 may have a bifurcated distal end that diverges further outward than a fixed end, and an outer circumferential surface of the distal end may protrude outward to prevent removal of the reciprocating lever 510.

[0461] (b) in FIG. 18 shows an arrangement structure of a support and a shaft coupling portion.

[0462] The support part 800 may include a seating groove 822 defined as the support plate 810 is recessed into the outer circumferential surface of the shaft coupling portion 820.

[0463] A diameter of the seating groove 822 may correspond to the outer circumferential surface of the support bearing 530.

[0464] Accordingly, the support bearing 530 may be supported by being seated in the seat groove 822.

[0465] A passage hole 821 through which the support shaft 410 passes may be defined in an inner circumferential surface of the seat groove 822.

[0466] That is, the support frame 800 may include the passage hole 821 through which at least a portion of the power transmitter passes, and the seating groove 822 that supports a bearing that is seated in the passage hole and rotatably supports the power transmitter.

[0467] The reciprocating rotating part 500 may be coupled to the power transmitter on the support frame 810 to support the power transmitter or transmit the load of the power transmitter to the support frame 810.

[0468] (c) in FIG. 18 shows a coupling structure of a power shaft and a reciprocating lever.

[0469] The eccentric shaft body 311 may extend from the power shaft 240, and the fixing clip 313 that prevents removal of the eccentric bearing may be coupled to a free end of the eccentric shaft body 311. The fixing clip 313 may be formed integrally with the eccentric shaft body 311.

[0470] The eccentric bearing 312 may be coupled to an outer circumferential surface of the eccentric shaft body 311.

[0471] The eccentric shaft 310 may further include a fixing cylinder 314 coupled to the outer circumferential surface of the eccentric shaft body 311 to fix the eccentric bearing 312.

[0472] Protrusions spaced apart from each other along the height direction may be disposed on an outer circumferential surface of the fixing cylinder 314 and may be in contact with the inner circumferential surface of the eccentric bearing 312. As a result, a coupling force between the eccentric bearing 312 and the eccentric shaft body 311 may be strengthened.

[0473] The eccentric bearing 312 may be formed as a sponge or the like having elasticity and resilience to absorb impact.

[0474] FIG. 19 shows a structure supporting a displacement generator in a moving hanger 100 of the present disclosure.

[0475] Referring to (a) in FIG. 19, the pulley support 234 defines the cut groove 2345 in one side of a seating body 2343 into which the reciprocating lever 510 is inserted. The seating body 2343 may be formed as a metal plate that may be seated on the support plate 810.

[0476] The support body 2341 may extend upward from an inner circumferential surface of the seating body 2343, and the bearing support 2342 may be disposed on an inner circumferential surface of the support body 2341.

[0477] The support body 2341 may also have one side open to define the cut groove 2345.

[0478] The cut groove 2345 may have a width that allows the main lever 510 to reciprocate at a sufficient rotation angle.

[0479] The seating body 2343 includes a plurality of coupling holes 2347 into which the respective pulley bolts coupled to the support plate 810 are coupled, spaced apart from each other by a certain distance along a circumference of the seating body 2343.

[0480] Referring to (b) in FIG. 19, the transmission pulley 232 is coupled to the belt 233 on the pulley support 234 and generates considerable vibration while rotating.

[0481] In addition, when the belt 233 is coupled while the pulley support 234 accommodates the power shaft 240 therein and the transmission pulley 232 is seated, there is a risk that the pulley support 234 may move even slightly toward the rotation shaft 220 because of a tension of the belt 233.

[0482] In addition, the power shaft 240 coupled to the transmission pulley 232 and supported by the pulley support 234 receives a force of being pulled toward the rotation shaft 220 or a force of vibrating in various directions because of the tension provided by the belt 233.

[0483] In particular, the pulley support 234, which is subjected to vibrations generated when the power transmitter 400 performs the reciprocating rotational motion by the power shaft 240, is subjected to strong vibrations.

[0484] In addition, when an installation position of the pulley support 234 varies, a location of the cut groove 2435 changes, so that there is a risk that the pulley support 234 interferes with the reciprocating motion of the main lever 510.

[0485] Therefore, to strengthen a fixing force for fixing the pulley support 234 to the support part 800 and prevent the pulley support 234 from sliding even at a certain distance, the pulley support 234 may further include a support protrusion 2346 inserted into the support plate 810.

[0486] The support protrusion 2346 may protrude from a lower portion of the seating body 2343 and may be disposed to face the main lever 511. As a result, not only may be the location where the cut groove 2435 is defined naturally guided, but also the pulley support 234 may be firmly fixed to the support plate 810.

[0487] In addition, even when the tension is applied to the belt 233, the installation location of the pulley support 234 may be fixed without arbitrarily varying by the support projection 2346.

[0488] The support plate 810 may include a protrusion accommodating hole 814 through which the support protrusion 2346 may extend and be coupled. In one example, the support plate 810 may further include a coupling hole 815 into which the pulley bolt is coupled.

[0489] FIG. 20 shows a structure of a power transmitter in a moving hanger 100 of the present disclosure.

[0490] Referring to (a) in FIG. 20, the power transmitter 400 may include the support shaft 410 that receives the power from the driver 200 by extending through the support plate 810, and the auxiliary support part 420 that is coupled to the support shaft 410 and rotates together with the support shaft 410.

[0491] The hanger 900 may be coupled and fixed to the auxiliary support part 420.

[0492] The support shaft 410 may be coupled and fixed to an upper portion of the auxiliary support part 420, and the support shaft 410 may be coupled at an exact center of a top surface of the auxiliary support part 420.

[0493] Referring to (b) in FIG. 20, the support shaft 410 may include a convey body 411 that is coupled to the reciprocating rotating part 500 and receives the power of the driver 200, and an extension part 412 that extends downward from the convey body 411 and is seated on the auxiliary support part 420.

[0494] The convey body 411 may have a screw thread along an outer circumferential surface thereof, so that the convey body 411 may be directly coupled to the reciprocating rotating part 500, or may be coupled to the transmitter coupling portion 415 and fixed to the reciprocating rotating part 500.

[0495] The extension part 412 may have a diameter larger than that of the convey body 411, and the diameter thereof may expand continuously or in a stepwise manner as it extends downward from the convey body 411. As a result, the extension part 412 may stably support the auxiliary support part 420 while ensuring durability.

[0496] The auxiliary support part 420 may include a shaft support 425 on which the extension part 412 is seated, and a coupling tube 424 that extends upward from the shaft support 425 and accommodates a portion of an outer circumferential surface of the extension part 412 therein.

[0497] The auxiliary support part 420 may include a plate body 421 that extends downward from the shaft support 425 and is coupled with the hanger 900.

[0498] The plate body 421 may have a length that is much greater than a cross-sectional area. A support projection 423 that protrudes to one side from a distal end of the plate body 421 to support the hanger part 700 may be disposed.

[0499] The plate body 421 may be formed in a rectangular parallelepiped shape.

[0500] The plate body 421 may include first surfaces on which stands 730, which will be described below, are disposed and which extend in the vertical direction to form both side surfaces of the plate body 421, and a second surface that has an area size smaller than that of the first surface and connects the first surfaces to each other.

[0501] The hanger part 700 may be formed in any shape as long as it is able to hang the ring 910 of the clothes hanger 900 thereon by being coupled to the plate body 421.

[0502] The hanger part 700 may include a hanger body 710 that includes a hanger groove 720 in which the plate body 421 is inserted in a direction of the second surface and is accommodated.

[0503] The stand 730 on which the ring 910 may be hung may protrude on at least one of both side surfaces of the hanger body 710.

[0504] The stand 730 may include a stand groove 740 in which the ring 910 is inserted and supported in an upper portion thereof, and may include a recessed portion 750 recessed to disperse the load in a side surface thereof.

[0505] The stand 730 may have a width corresponding to a width of the hanger body 710, and may be disposed at a lower side of the hanger body 710.

[0506] The hanger body 710 may support both surfaces of the plate body 421, so that even when the plate body 421 performs the reciprocating rotational motion based on the support shaft 410, a coupling force may be stably maintained.

[0507] The support projection 423 may support a bottom surface of the hanger body 710, so that the hanger body 710 may be prevented from being removed from the plate body 421.

[0508] FIG. 21 shows a detailed structure of a power transmitter in a moving hanger 100 of the present disclosure.

[0509] Referring to (a) in FIG. 21, the hanger body 710 and the plate body 421 may be coupled with each other via a fastening member.

[0510] Specifically, the plate body 421 may have an input hole 426 into which the fastening member may be inserted and a fastening hole 427 through which the fastening member passes and is coupled in the second surface.

[0511] The fastening hole 427 may be defined in an area corresponding to the hanger groove 720 in the hanger body 710, and the input hole 426 may be defined to face one surface of the hanger body 710 facing the hanger groove 720.

[0512] The fastening member may be coupled with the fastening hole 427 by being inserted into the input hole 426 through the hanger body 710. As a result, the hanger part 700 may be firmly coupled with the auxiliary support part 420 via the fastening member.

[0513] Referring to (b) in FIG. 21, the support shaft 410 may include the convey body 411 having a screw thread so as to be coupled to the transmitter coupling portion 415 through the inner casing 20, the support part 800, and the reciprocating lever 510, and the extension part 412 that extends from the convey body 411 and is coupled to the auxiliary support part 420.

[0514] The convey body 411 may be formed in a cylindrical shape, but may have the screw thread formed on the outer circumferential surface thereof.

[0515] The extension part 412 may include a coupling pillar 4121 that is disposed under the convey body 411 and coupled to the reciprocating lever 510. The coupling pillar 4121 may be an area that is coupled to an inner circumferential surface of the main center hole 5115 of the main lever and an inner circumferential surface of the auxiliary center hole 5125 of the auxiliary lever.

[0516] The coupling pillar 4121 may have a polygonal cross-section instead of a curved one, unlike the convey body 411. In addition, the main center hole 5115 and the auxiliary center hole 5125 may also be formed in a shape corresponding to the cross-sectional shape of the coupling pillar 4121.

[0517] For example, the cross-section of the coupling pillar 4121 may be formed in a square shape.

[0518] As a result, the main center hole 5115 and the auxiliary center hole 5125 may be prevented from rotating idly around the coupling pillar 4121. Accordingly, the rotational power of the driver 200 transmitted to the main lever 510 and the auxiliary levers 512 may be fully transmitted to the support shafts 410, and the power transmitter 400 may perform the reciprocating rotational motion to maximize a performance of removing dust from the laundry.

[0519] The extension part 412 may include a lubricated pillar 4122 that extends from a lower portion of the coupling pillar 4121 and is rotatably supported on the support bearing 530.

[0520] The lubricated pillar 4122, as an area that is positioned downward of the main lever 510 and the auxiliary lever 512 and an area that is rotatably supported on the inner circumferential surface of the support bearing 530, may be an area that at least partially faces the support plate 800 or an area that is positioned upward of the support plate 800.

[0521] Unlike the coupling pillar 4121, the lubricated pillar 4122 may have a circular cross-section. Accordingly, the lubricated pillar 4122 may be able to rotate completely in the support bearing 530, and thus may not interfere with the reciprocating rotational motion of the support shaft 410.

[0522] The lubricated pillar 4122 may have a greater cross-sectional area than the coupling pillar 4121, thereby performing the reciprocating rotational motion while more stably supporting a load added thereto.

[0523] The extension part 412 may further include a support pillar 4123 that extends downward from the lubricated pillar 4122 and is coupled to the auxiliary support part 420. The support pillar 4123 may have a greater cross-sectional area than the lubricated pillar 4122. Accordingly, the support pillar 4123 may not only stably support the auxiliary support part 420, but may also stably transmit the transmitted rotational power to the auxiliary support part 420.

[0524] As a result, the support shaft 410 may become thicker in a stepwise manner as it goes downward.

[0525] A lower end of the support pillar 4123 may be recessed and coupled to the auxiliary support part 420.

[0526] The support shaft 410 is a component that supports the entire loads of the power transmitter 400, the hanger part 700, and the clothes hanger 900 and allows the power transmitter 400, the hanger part 700, and the clothes hanger 900 to perform the reciprocating rotational motion. Therefore, the support shaft 410 may be made of a rigid metal material to maintain durability even when the great torque, inertial force, excessive load, vibration, and the like are added thereto.

[0527] However, the auxiliary support part 420 has a much greater volume and a greater length than the support shaft 410, so that when the auxiliary support part 420 is made of a metal material, a weight thereof may become unnecessarily great, which makes the reciprocating rotational motion difficult. Therefore, the auxiliary support part 420 may be made of a material lighter than the metal material, such as a resin-based material.

[0528] Because the support shaft 410 and the auxiliary support part 420 are made of the different materials, there is a risk that, when the support shaft 410 and the auxiliary support part 420 are simply coupled to each other, the auxiliary support part 420 may rotate idly when the support shaft 410 rotates.

[0529] To prevent such problem, the support shaft 410 may include a support board 4124 that may allow the lower end of support pillar 4123 to be accommodated in and coupled to the auxiliary support part 420, may have an area size greater than that of the support pillar 4123, and may be accommodated in and coupled to the auxiliary support part 420.

[0530] In addition, the support shaft 410 may be formed with a chamfered portion 414 that is formed linearly on a portion of a side surface thereof so as to prevent the support shaft 410 from rotating idly in the auxiliary support part 420.

[0531] The chamfered portion 414 may strengthen a coupling force between the outer circumferential surface of the support shaft 410 and the inner circumferential surface of the auxiliary support part 420 by forming a portion of the outer circumferential surface of the cross-section of the support shaft 410 linearly rather than curved.

[0532] For example, the chamfered portion 414 may be formed on at least one of the support pillar 4123 and the support plate 4124.

[0533] The chamfered portion 414 may include a first chamfered portion 4141 formed on one or two sides of an outer circumferential surface of the support pillar 4123, and a second chamfered portion 4142 formed on one or two sides of an outer circumferential surface of the support plate 4124.

[0534] In this regard, the first chamfered portion 4141 and the second chamfered portion 4142 may be arranged to be staggered relative to a rotation direction of the support shaft 410.

[0535] That is, the second chamfered portion 4142 may not be directly disposed under the first chamfered portion 4141, but a curved surface may be disposed under the first chamfered portion 4141, and the second chamfered portion 4142 may be disposed at a location that does not face the first chamfered portion 4141.

[0536] When the first chamfered portion 4141 is disposed to face forward, the second chamfered portion 4142 may be oriented laterally.

[0537] As a result, the coupling tube 424 that is coupled to the first chamfered portion 4141 while accommodating the same and the shaft support 425 that is coupled to the second chamfered portion 4142 while accommodating the same may receive the rotational power in different directions, thereby preventing the auxiliary support part420 from rotating idly on the support shaft 410, and preventing stress from being concentrated on a specific area of the auxiliary support part 420.

[0538] FIG. 22 shows a power transmission structure of a moving hanger 100 of the present disclosure.

[0539] Referring to (a) in FIG. 22, the moving hanger 100 of the present disclosure allows the reciprocating rotating part 500 to which the power transmitter 400 is coupled to perform the reciprocating rotational motion.

[0540] The moving hanger 100 of the present disclosure does not convert the rotational energy of the driver 200 into a linear reciprocating motion of the power transmitter 400, the hanger part 700, the clothes hanger 900, and the reciprocating rotating part 500.

[0541] In other words, the moving hanger 100 of the present disclosure converts the energy of the driver 200 rotating the rotation shaft 220 into a motion of rotating the power transmitter 400, the hanger part 700, the clothes hanger 900, and the reciprocating rotating part 500, without converting the same into the linear motion.

[0542] As a result, the moving hanger 100 of the present disclosure may transfer all of the power generated during 360-degree rotation of the rotation shaft 220 as energy for performing the reciprocating rotational motion of the power transmitter 400, the hanger part 700, and the clothes hanger 900. Accordingly, the moving hanger 100 of the present disclosure may use the power generated from the driver 200 to shake the laundry during an entire time period in which the driver 200 operates. Therefore, the moving hanger 100 of the present disclosure may transfer sufficient oscillating force to the laundry even when the driver 200 operates at the low output, thereby effectively removing dust from the laundry.

[0543] In addition, even when the driver 200 operates for a short period of time, because the power generated from the driver 200 is transferred to the laundry during the entire time period in which the driver 200 operates, a time period for operating the moving hanger 100 may be reduced, and a laundry management cycle itself may be shortened.

[0544] The reciprocating rotating part 500 may include the receiving hole 5112 that receives the power from the eccentric shaft 310 and rotates, the transmitting hole 5113 that is coupled to the connector 600 and rotates, and the center hole 5115 that is coupled to a center of rotation 410 of the power transmitter 400 and rotates the power transmitter, based on the reciprocating lever 510.

[0545] A width or a diameter of the receiving hole 5112 may be set to be greater than a diameter of the eccentric shaft 310. The receiving hole 5112 may be longer in a length direction of the reciprocating lever 510.

[0546] However, the diameter of the receiving hole 5112 may be set to be smaller than a radius of rotation R of the eccentric shaft 310.

[0547] The eccentric shaft 310 may be accommodated in the receiving hole 5112 and may pass through points I, II, III, and IV while rotating with a diameter larger than the width of the receiving hole 5112. When the eccentric shaft 310 is at the point II, the receiving hole 5112 is pushed to the right and moved to a right point 5112a, and when the eccentric shaft 310 is at the point IV, the receiving hole 5112 is pushed to the left and moved to a left point 5112b.

[0548] In such process, the transmitting hole 5113 moves to the left point 5113a and the right point 5113b.

[0549] In addition, when the eccentric shaft 310 is at the points I and III, the receiving hole 5112, the transmitting hole 5113, and the support shaft 410 are placed in correct locations.

[0550] As such, whenever the eccentric shaft 310 rotates once, the reciprocating lever 510 may perform the reciprocating rotational motion in the left and right direction once, the support shaft 410 may also perform the reciprocating rotational motion once, and another reciprocating lever 510 may also perform the reciprocating rotational motion once by the connector 600.

[0551] In addition, when the eccentric shaft 310 passes the point I, which is a 0-degree location, and the point III, which is a 180-degree location, based on a center of rotation of a rotation trajectory thereof, the power of the eccentric shaft 310 is completely transmitted to the support shaft 410 and transmitted to the transmitting hole 5113 as it is.

[0552] For example, when the eccentric shaft 310 rotates clockwise, a force F1 of moving to the right when the eccentric shaft 310 passes the point I is transmitted as it is to the support shaft 410 and the transmitting hole 5113 as the force F1 of moving to the left.

[0553] In addition, when the eccentric shaft 310 passes the point III, a force F3 of moving to the left is transmitted as it is to the support shaft 410 and the transmitting hole 5113 as the force F3 of moving to the right.

[0554] However, even when the eccentric shaft 310 passes the point II, which is a 90-degree location, and the point IV, which is a 270-degree location, based on the center of rotation of the rotation trajectory thereof, the power of the eccentric shaft 310 is still transmitted to the support shaft 410 and the transmitting hole 5113.

[0555] For example, when the eccentric shaft 310 moves clockwise, a force F2 of moving downward when the eccentric shaft 310 passes the point II is transmitted by being divided into a force Fa parallel to the direction in which the transmitting hole 5113 and the support shaft 410 rotate and a force Fb perpendicular to the direction in which the transmitting hole 5113 and the support shaft 410 rotate.

[0556] Therefore, the force F2 generated from the eccentric shaft 310 is still transmitted to the transmitting hole 5113 and the support shaft 410 as much as the force Fa parallel to the direction in which the transmitting hole 5113 and the support shaft 410 rotate.

[0557] In addition, when the eccentric shaft 310 corresponds to the point IV, the Fa will be reversed only in direction and transmitted to the transmitting hole 5113 and the support shaft 410.

[0558] As a result, the moving hanger 100 of the present disclosure may always transmit the power received from the driver 200 to the support shaft 410 and the transmitting hole 5113, regardless of the location of the eccentric shaft 310.

[0559] This is a significant difference from the existing laundry treating apparatus, which does not transmit any power to the power transmitter 400 and the clothes hanger 900, but dissipates the power when the eccentric shaft 310 rotates at the points II and IV.

[0560] Referring to (b) in FIG. 22, the receiving hole 5112 is defined to be spaced apart from the support shaft 410 or the center hole 5115 by a maximum of L2 and a minimum of L1.

[0561] In addition, the receiving hole 5112 is defined to be spaced apart from the transmitting hole 5113 by a distance greater than L2.

[0562] In one example, a torque T is required to rotate the support shaft 410, and the torque T is proportional to the force that generates the rotational power and a distance L from the support shaft 410, which is a point of action.

[0563] In this regard, the eccentric shaft 310 is positioned at a maximum of L2 and a minimum of L1 from the support shaft 410 while rotating once, and continuously generates the force F that rotates the support shaft 410.

[0564] In addition, the eccentric shaft 310 is always positioned to be spaced apart from the support shaft 410 by a distance greater than L1 throughout entire rotation thereof.

[0565] As a result, the support shaft 410 is always applied with the torque generated from the rotation of the eccentric shaft 310 without a point where the torque becomes 0. Therefore, whenever the eccentric shaft 310 rotates 360 degrees, the torque may always be applied to the support shaft 410, and the power transmitted to the eccentric shaft 310 may always act as the power to rotate the support shaft 410.

[0566] FIG. 23 shows a process in which the reciprocating rotating part performs a reciprocating rotational motion in detail.

[0567] As shown in (b) in FIG. 23, the eccentric shaft 310 may be disposed at a location I and be disposed at one end or a distal end of the main receiving hole 5112.

[0568] Thereafter, when the power shaft 240 rotates 90 degrees clockwise, because the eccentric shaft 310 is spaced apart from a center of rotation of the power shaft 240 by 1 / 2R, the eccentric shaft 310 may move to the right by 1 / 2R.

[0569] In addition, the main center hole 5112 also moves to the right, and the main body 5111 rotates the support shaft 410 clockwise. Accordingly, the power transmitter 400 coupled to the main lever 511 rotates clockwise, and the hanger part 700 coupled to the power transmitter 400 and the clothes hanger 900 hung on the hanger part 700 also rotate clockwise. Accordingly, the laundry also rotates clockwise.

[0570] In one example, the main transmitting hole 5113 moves to the left in an opposite direction to the main receiving hole 5112 centered on the support shaft 410. Accordingly, the connector 600 is moved to the left, and all of the auxiliary levers 512 coupled to the connector 600 are moved to the left, so that all of the power transmitters 400 coupled to the auxiliary levers 512 may be rotated clockwise.

[0571] Thereafter, the power shaft 310 is disposed at a location III when rotating 90 degrees, and is disposed at a location IV when rotating 180 degrees.

[0572] In such process, the main center hole 5112 moves to the left again and then moves further to the left, and the main lever 511 moves counterclockwise. As a result, the main lever 511 may be disposed in states in (b) and (a) in FIG. 22.

[0573] In such process, the power transmitter 400 coupled to the main lever 511 rotates clockwise, and the hanger part 700 coupled to the power transmitter 400 and the clothes hanger 900 hung on the hanger part 700 also rotate counterclockwise. Accordingly, the laundry also rotates counterclockwise.

[0574] In one example, the main transmitting hole 5113 moves to the right in an opposite direction to the main receiving hole 5112 centered on the support shaft 410. Accordingly, the connector 600 is moved to the right, and all of the auxiliary levers 512 coupled to the connector 600 are moved to the left, so that all of the power transmitters 400 coupled to the auxiliary levers 512 may be rotated counterclockwise.

[0575] When the power shaft 240 continuously rotates clockwise, the eccentric shaft 310 may also continuously rotate, and the aforementioned process may be repeated infinitely.

[0576] In one example, when the power shaft 240 continuously rotates counterclockwise, the eccentric shaft 310 may also continuously rotate counterclockwise, and the aforementioned process may be repeated infinitely in a reverse order.

[0577] As a result, the laundry may be shaken in the left and right direction centered on the support shaft 410 of the mounted power transmitter 400.

[0578] FIG. 24 shows an embodiment of supporting a driver in a moving hanger 100 of the present disclosure.

[0579] The support plate 810 is disposed to overlap the power transmitter 400. In this regard, the driver 200 is disposed to be spaced apart from the power transmitter 400 in the front and rear direction to secure a length for generating the rotational power or the torque that allows the power transmitter 400 perform the reciprocating rotational motion.

[0580] In this case, an area in one side of the driver 200 may be supported by being seated on the support plate 810, but a remaining area may be difficult to be seated on the support plate 810.

[0581] When the driver 200 is disposed at a rear portion of the support plate 810, there is a concern that a rear portion of the driver 200 may not be supported by the support plate 810 and may be supported by the top surface of the inner casing 20.

[0582] The motor 210 may include a first coupling portion 2141 that is seated on the support plate 810 and fixes the motor 210, and a second coupling portion 2142 that is spaced apart from the support plate 810 and fixes the motor 210.

[0583] The pulley support 234 may include a first fixing portion 2347 that is seated on the support plate 810 and fixes the pulley support, and a second fixing portion 2348 that is spaced apart from the support plate 810 and fixes the pulley support.

[0584] A separate motor support member 25 and a pulley support member 26 may be formed on the top surface of the inner casing 20 to support the motor 210 and the pulley support 234.

[0585] FIG. 25 shows an additional embodiment of supporting a driver in a moving hanger 100 of the present disclosure.

[0586] Because the top surface of the inner casing 20 is made of a resin-based material, there is a risk of damage when the vibration or the load is transmitted from the motor 210 and the pulley support 234.

[0587] Therefore, the support part 800 of the present disclosure may include an expansion plate 830 that may extend forward or rearward from the support plate 810 or may be coupled to a front portion or a rear portion of the support plate 810 to expand an area size of the support part 800.

[0588] (a) in FIG. 25 shows a structure in which the motor 210 and the pulley support 234 are supported by the support plate 810 and the expansion plate 830 in a shared manner, and (b) in FIG. 25 shows structures of the support plate 810 and the expansion plate 830.

[0589] The expansion plate 830 may extend from a rear surface or a front surface of the support plate 810 and be coupled to the support frame 12.

[0590] The expansion plate 830 may be formed in the same shape as the support plate 810.

[0591] The motor 210 and the pulley support 234 may be supported by the support plate 810 and the expansion plate 830 in the shared manner.

[0592] The motor 210 may include the first coupling portion 2141 that is seated on the support plate 810 and fixes the motor 210, and the second coupling portion 2142 that is spaced apart from the support plate 810 and seated on the expansion plate 830 and fixes the motor 210.

[0593] The pulley support 234 may include the first fixing portion 2347 that is seated on the support plate 810 and fixes the pulley support, and the second fixing portion 2348 that is spaced apart from the support plate 810 and seated on the expansion plate 830 and fixes the pulley support.

[0594] FIG. 26 shows another embodiment of supporting a driver in a moving hanger 100 of the present disclosure.

[0595] (a) in FIG. 26 shows a structure in which a support bar is disposed separately. (b) in FIG. 26 shows a configuration in which the support bar supports the driver 200.

[0596] The support part 800 of the present disclosure may include a separate support bar 870 that is disposed separately from the support plate 810, but supports the driver 200 in front of or at the rear of the support plate 810.

[0597] One side of the driver 200 may be supported by being seated on the support plate 810, and the other side of the driver 200 may be supported by being seated on the support bar 870.

[0598] The support bar 870 may be formed in a frame shape that is narrower than the support plate 810, and may be disposed to be spaced apart from the support plate 810. The driver 200 may be disposed in a space in which the support plate 810 and the support bar 870 are spaced apart from each other.

[0599] The motor 210 may include the first coupling portion 2141 that is seated on the support plate 810 and fixes the motor 210, and the second coupling portion 2142 that is seated on the support bar 870 by being spaced apart from the support plate 810 and fixes the motor 210.

[0600] The pulley support 234 may include the first fixing portion 2347 that is seated on the support plate 810 and fixes the pulley support, and the second fixing portion 2348 that is seated on the expansion plate 870 by being spaced apart from the support plate 810 and fixes the pulley support.

[0601] The motor 210 may be disposed to be further spaced apart from the support plate 810 than the pulley support 243.

[0602] To support such motor 210, the support bar 870 may include a first body 871 coupled to the support frame 12, a second body 872 extending obliquely from the first body and moving away from the support plate 810, a third body 873 extending from the second body 872 to the opposite support frame 12, a fourth body 874 extending from the third body 873 toward the pulley support 243, and a fifth body 875 extending from the fourth body 874 and seated and fixed on the opposite support frame 12.

[0603] The pulley support 243 may be supported by being coupled to the fifth body 875, and the driver 210 may be positioned between the first body 871, the second body 872, the third body 873, the fourth body 874, and the support plate 810, and may be supported by being seated on the support plate 810 and the third body 873.

[0604] FIG. 27 shows another embodiment of a moving hanger 100 of the present disclosure.

[0605] The moving hanger 100 of the present disclosure may be largely divided into the driver 200 and the transmitter 230 that generate and transmit the power, and the reciprocating rotating part 500, the connector 600, and the power transmitter 400 that move with the power.

[0606] The support part 800 may include a separate additional plate 840 supporting the driver 200 and the transmitter 230, and the support plate 810 supporting the reciprocating rotating part 500, the connector 600, and the power transmitter 400.

[0607] The additional plate 840 may be spaced apart from the support plate 810 and coupled and fixed to the support frame 12.

[0608] The additional plate 840 may be spaced apart from the support plate 810, thereby preventing vibration of the support plate 810 and vibration of the additional plate 840 from overlapping or interfering with each other.

[0609] The additional plate 840 may include an additional body 841 that supports the motor 210 and the transmitter 230, a frame body 843 that supports the additional body 841 to the support frame, and a connecting body 842 that connects the additional body 841 with the frame body 843.

[0610] The additional body 841 may be positioned downward of the frame body 843 to secure a space where the motor 210 and the transmitter 230 are seated, and the connecting body 842 may be positioned at an angle.

[0611] The additional body 841 may include an insertion hole 8411 into which the motor 210 is inserted, and a support groove 8412 into which an outer circumferential surface of the motor 210 is coupled and supported.

[0612] The additional body 841 may include a pulley hole 8413 spaced apart from the insertion hole 8411 and in which the pulley support 243 is seated. The pulley hole 8413 may have a diameter smaller than that of the pulley support 243 to support the pulley support 234, but may allow the power shaft 240 or the eccentric shaft 310 to pass therethrough as is.

[0613] The additional body 841 may be disposed upward of the support plate 810.

[0614] The power transmitter 400 may be supported by extending through the support plate 810, and the reciprocating lever 510 may be coupled to the power transmitter 400 to support the power transmitter 400 on the support plate 810.

[0615] The reciprocating levers 510 may include the main lever 511 that receives the power from the transmitter 230 and performs the reciprocating rotational motion, and the auxiliary levers 512 that are connected to the main lever 511 via the link bar 610 and rotate together with the main lever 511.

[0616] Unlike in the previous embodiment, the link bar 610 may connect a lower end of the main lever 511 with a lower end of the auxiliary lever 512.

[0617] The link bar 610 may include the link body 611 and the hook coupling portion 612 similar to the previous embodiment.

[0618] The link bar 610 may be disposed on an opposite side of the driver 200 or the transmitter 230 with respect to the support plate 810. As a result, the link bar 610 may be prevented from interfering with the driver 200 or the transmitter 230 and the displacement generator 300.

[0619] For example, the link bar 610 may be disposed either in front of or at the rear of the support plate 810, and the driver 200 and the transmitter 230 may be disposed on an opposite side of support plate 810.

[0620] As a result, the support plate 810 may be disposed between the connector 600 and the driver 200 to partition the connector 600 and the driver 200 from each other. Accordingly, while preventing the connector 600 and the driver 200 from interfering with each other, components may be stably Installed and arranged.

[0621] FIG. 28 shows another embodiment of a moving hanger 100 of the present disclosure.

[0622] Similarly to the previous embodiment, the moving hanger 100 of the present disclosure shown in FIG. 28 may allow the power transmitter 400 to perform the reciprocating rotational motion via the driver 200, the transmitter 230, and the reciprocating rotating part 500 to oscillate the hanger part 700 and the clothes hanger 900 hung on the power transmitter 400 and remove dust.

[0623] The connector 600 of the moving hanger 100 may connect the plurality of power transmitters 400 to each other, so that when one of the power transmitters 400 performs the reciprocating rotational motion, the remaining power transmitters 400 may also perform the reciprocating rotational motion

[0624] However, the connector 600 may include a plurality of links 620 that connect the plurality of power transmitters to each other.

[0625] For example, the plurality of links 620 may be disposed at front and rear portions of the power transmitters 400 and connect the power transmitters 400 to each other.

[0626] Specifically, the reciprocating rotating part 500 may be coupled to or extended from the power transmitter 400 upward of the support part 800 to rotate the power transmitter 400.

[0627] The plurality of links 620 may connect all of the reciprocating rotating parts 500 respectively disposed on the power transmitters 400 to each other, thereby connecting all of the power transmitters 400 to each other.

[0628] The plurality of links 620 may connect not only respective one ends or front portions of the reciprocating rotating parts 500 to each other, but also the other ends or rear portions of the reciprocating rotating parts 500 to each other.

[0629] Therefore, when one reciprocating rotating part 500 rotates, all the other reciprocating rotating parts 500 may rotate via the plurality of links 620, and the plurality of power transmitters 400 may rotate together.

[0630] Because the moving hanger 100 has the plurality of links 620 arranged on both sides or both the front and rear portions of the reciprocating rotating part 500, when the power of the driver 200 is received at the front or rear portion of the reciprocating rotating part 500, there is a concern that it may interfere with the plurality of links 620.

[0631] The moving hanger 100 may be equipped such that an upper portion of the reciprocating rotating part 500 receives the power of the driver 200. To this end, the reciprocating rotating part 500 may include a rotary rod 523 that may protrude or extend upward and may perform the reciprocating rotational motion by the driver 200.

[0632] The rotary rod 523 may be formed in a columnar or shaft shape, but may be formed in any shape as long as it is able to rotate a rotary plate 520.

[0633] The rotary rod 523 may be disposed in all of the reciprocating rotating parts 500, but may be disposed in only one reciprocating rotating part 500.

[0634] The power transmitter 400 may include the support shaft 410 that passes through the inner casing 20 and the support part 800 and performs the reciprocating rotational motion by the reciprocating rotating part 500.

[0635] The auxiliary support part 420 may be coupled to the lower portion of the support shaft 410. However, the hanger part 700 may be directly coupled to the lower portion of the support shaft 410.

[0636] The support shaft 410 and the reciprocating rotating part 500 may be eqiupped as separate members and coupled to each other, or the support shaft 410 and the reciprocating rotating part 500 may be equipped integrally.

[0637] The reciprocating rotating part 500 may be disposed at an upper end of the support shaft 410, and may have a diameter larger than that of the support shaft 410 and thus may easily rotate even with a small external force.

[0638] Therefore, when the rotary rod 523 rotates and one reciprocating rotating part 500 performs the reciprocating rotational motion, all of the reciprocating rotating parts 500 may be rotated by the plurality of links 620.

[0639] As a result, all of the power transmitters 400 may perform the reciprocating rotational motion based on the support shaft 410.

[0640] FIG. 29 shows a specific structure of a moving hanger 100 shown in FIG. 28.

[0641] The connector 600 may include the plurality of links 620 that connect the plurality of reciprocating rotating parts 500 to each other and rotate the plurality of reciprocating rotating parts 500 integrally.

[0642] The plurality of links 620 may be arranged to be spaced apart from each other to both sides of centers of rotation of the plurality of reciprocating rotating parts 500.

[0643] The plurality of links 620 includes a first link 621 connecting respective one sides of the plurality of reciprocating rotating parts 500 to each other and a second link 622 connecting the other sides of the plurality of reciprocating rotating parts 500 to each other and facing the first link.

[0644] Referring to (a) in FIG. 29, the reciprocating rotating part 500 may include the rotary plate 520 coupled to the upper end of the support shaft 410. The rotary plate 520 may be formed in a circular shape and may have a diameter larger than that of the support shaft 410.

[0645] However, as long as the rotary plate 520 is able to be connected to the plurality of links 620 and perform the reciprocating rotational motion, it may be equipped as the reciprocating lever 510.

[0646] The plurality of power transmitters 400 may be arranged to be spaced apart from each other by a certain distance along the length direction of the support part 800 or the width direction of the inner casing 20.

[0647] The rotary plate 520 may be coupled to the upper portion of the power transmitter 400 or extend from the upper portion of the power transmitter 400.

[0648] The rotary plate 520 may perform the reciprocating rotational motion relative to the power transmitter 400 at a location upward of the support part 800.

[0649] The support part 800 may include a seating plate 860 that may be seated on the support plate 810 to support the rotary plate 520 so as to support the reciprocating rotational motion of the rotary plate 520.

[0650] The seating plate 860 may be made of a resin-based material with a low friction force or a lubricating material, and may be seated on and fixed to the support plate 810.

[0651] The plurality of links 620 may connect all the one sides of the plurality of rotary plates 520 to each other and connect all the other sides thereof to each other, respectively. Because the plurality of rotary plates 520 are arranged to be spaced apart from each other in the width direction of the inner casing 20, the plurality of links 620 may connect all the front portions of the rotary plates 520 to each other and connect all the rear portions of the rotary plates 520 to each other, respectively.

[0652] The plurality of links 620 may include the first link 621 that connects the front portions of the plurality of rotary plates 520 to each other, and the second link 622 that connects the rear portions of the plurality of rotary plates 502 to each other. The first link 621 and the second link 622 may be coupled to an outer circumferential surface or an outermost surface of the rotary plate 520 to effectively rotate the rotary plate 520.

[0653] The rotary rod 523 that receives the power from the driver 200 may be disposed on one of the plurality of rotary plates 520.

[0654] The rotary rod 523 may extend upward of the one of the rotary plates 520, and may serve as the center of rotation of the rotary plate 520. The rotary rod 523 may be formed integrally with the support shaft 410, or may be disposed parallel to the support shaft 410.

[0655] A diameter of the rotary rod 523 may be set smaller than the diameter of the rotary plate 520.

[0656] Referring to (b) in FIG. 29, the driver 200 may rotate the rotary rod 523 at a location upward of the inner casing 20.

[0657] Specifically, the driver 200 may include the motor 210 supported by the support part 800, the power shaft 240 that rotates at the fixed location by the motor 210, and the displacement generator 300 that is coupled to the power shaft 240 and generates the displacement that allows the rotary rod 523 to rotate.

[0658] The displacement generator 300 may be coupled to the reciprocating rotating part 500 at a location between the first link 621 and the second link 622.

[0659] The displacement generator 300 may include a rotary arm 330 that has one end coupled to the rotary rod 534 and the other end rotatable along a predetermined radial trajectory by the rotation of the power shaft 240.

[0660] That is, the displacement generator 300 may be coupled to the rotary rod 534 corresponding to the center of rotation of the reciprocating rotating part 500.

[0661] Therefore, when the rotary arm 330 rotates along the predetermined radial trajectory, the rotary rod 523 may perform the reciprocating rotational motion.

[0662] FIG. 30 is an exploded perspective view of a moving hanger 100 shown in FIG. 28.

[0663] The number of power transmitters 400 and the number of rotary plates 520 may be equal to each other, and each rotary plate 520 may be disposed for each power transmitter 400.

[0664] The power transmitter 400 may include the support shaft 410 that passes through the support plate 810 and is exposed to the accommodating space 21.

[0665] The rotary plate 520 may be coupled to or integrally formed with the upper portion of the support shaft 410.

[0666] The rotary plates 520 may include a main rotary plate 521 coupled or extended to the support shaft 410 and including the rotary rod 523, and an auxiliary rotary plate 522 coupled or extended to the support shaft 410 that does not have the main rotary plate 521.

[0667] The main rotary plate 521 may be disposed only on one power transmitter 400, and the auxiliary rotary plates 522 may be installed on the remaining power transmitters 400.

[0668] The main rotary plate 521 and the auxiliary rotary plates 522 may be connected to each other by the plurality of links 620.

[0669] In other words, the reciprocating rotating parts 500 include the main rotary plate 521 that is coupled to the displacement generator 300 and performs the reciprocating rotational motion, and the auxiliary rotary plates 522 that are coupled to the remaining power transmitters spaced apart from the main rotary plate and rotate the power transmitters.

[0670] The first link 621 may connect one side of the main rotary plate and respective one sides of the auxiliary rotary plates to each other, and the second link 622 may connect the other side of the main rotary plate and the other sides of the auxiliary rotary plates to each other.

[0671] In other words, the first link 621 may connect the respective one sides of the main rotary plate 521 and the auxiliary rotary plates 522 based on the support shaft 410 to each other, and the second link 622 may connect the other sides of the main rotary plate 521 and the auxiliary rotary plates 522 based on the support shaft 410 to each other.

[0672] The first link 621 and the second link 622 may have the same length, and may have a length to connect all of the rotary plates 520 to each other.

[0673] The rotary plates 520 may include rotary plate holes 5211 and 5221 into which the fastening members coupled to the first link 621 and the second link 622 may be coupled.

[0674] Specifically, the main rotary plate 521 may include main rotary plate holes 5211 that are spaced apart from the support shaft 410 and the rotary rod 523 and are symmetric with each other around the support shaft 410 and the rotary rod 523. The main rotary plate holes 5211 may be defined close to the outer circumferential surface of the main rotary plate 521.

[0675] The auxiliary rotary plate 522 may include auxiliary rotary plate holes 5221 that are spaced apart from the support shaft 410 and are symmetric with each other around the support shaft 410. The auxiliary rotary plate holes 5221 may be defined close to the outer circumferential surface of the auxiliary rotary plate 522.

[0676] The plurality of links 620 may include link holes 623 through which rivets 524 that are inserted into and coupled with the rotary plate holes may extend. The number of link holes 623 may correspond to the number of power transmitters 400 arranged along the length of the first link 621 and the second link 622.

[0677] The first link 621 and the second link 622 may be set to have the same distance from the main rotary plate and the auxiliary rotary plate, respectively.

[0678] The first link 621 and the second link 622 may be coupled to the rotary plate 520 so as to always maintain a parallel state.

[0679] The main rotary plate 521 and the auxiliary rotary plate 522 may have the same length, diameter, or area size. The first link 621 and the second link 622 may be coupled to both ends of the main rotary plate and both ends of the auxiliary rotary plate, thereby rotating the main rotary plate 521 and the auxiliary rotary plate 522 at a larger angle with less motion.

[0680] The hanger part 700 may be coupled to a lower end of the support shaft 410. The hanger part 700 may include a hanging hole 710 coupled to the support shaft 410, and the stand groove 740 in which the ring 910 is seated in one of both sides of the hanging hole 710.

[0681] A lower clip 429 supporting a lower portion of the hanger part 700 may be coupled to the lower end of the support shaft 410, and an upper clip 428 supporting an upper portion of the hanger part 700 may be coupled to a middle portion of the support shaft 410.

[0682] In addition, the hanger part 700 may additionally include an extending member 760 that passes through one surface of the hanger to extend through the outer circumferential surface of the support shaft 410.

[0683] Accordingly, the hanger part 700 is firmly coupled to the support shaft 410, so that even when the hanger part 700 performs the reciprocating rotational motion in the left and right direction, the hanger part 700 may be prevented from rotating idly around the support shaft 410 or being removed from the support shaft 410.

[0684] The support shaft 410 may be equipped as a metal pipe to ensure durability. In one example, as long as the support shaft 410 is not twisted even by the rotational torque and is able to sufficiently support the loads of the hanger part 700, the clothes hanger 900, and the laundry, the support shaft 410 may be made of a resin-based material.

[0685] In addition, the support shaft 410 may have a diameter much smaller than that of the rotary plate 520 to minimize a rotational moment of inertia.

[0686] The support part 800 may include the auxiliary plate 880 that is seated on the support plate 810 and supports the rotary plate 520.

[0687] At least one of the rotary plate 520 and the auxiliary plate 880 may be made of a material having lower frictional force than metal. For example, both the rotary plate 520 and the auxiliary plate 880 may be made of a resin-based material.

[0688] The auxiliary plate 800 may include the auxiliary body 881 that is seated on the support part 800, the auxiliary through-hole 882 that allows the support shaft 410 to pass therethrough along the length direction of the auxiliary body 881, a retaining rib 883 that extends from an outer circumferential surface of the auxiliary through-hole 882 and the auxiliary body 881 to maintain the rigidity of the auxiliary plate 880, and a recessed space 884 that is recessed downward from the auxiliary body 881 to define a space where the load may be distributed between an inner peripheral surface of the auxiliary body 881 and the retaining rib 833.

[0689] The rotary plate 520 may be rotatably supported by the retaining rib 883 or the auxiliary through-hole 882. However, it is preferable that the rotary plate 520 rotates while being spaced apart from the auxiliary plate 800.

[0690] The support bearing 530 that rotatably supports the support shaft 410 may be seated on and fixed to the auxiliary through-hole 882.

[0691] FIG. 31 shows an operating principle of a moving hanger 100 shown in FIG. 28.

[0692] (a) in FIG. 31 shows operating states of the reciprocating rotating parts 500, the power transmitters 400, and the plurality of links 620 as viewed from above the support part 800, and (b) in FIG. 31 conceptually shows operations of the reciprocating rotating parts 500, the power transmitters 400, and the plurality of links 620.

[0693] First, the first link 621 and the second link 622 may be arranged to face each other based on the power transmitter 400. The first link 621 may be coupled to the respective one sides of the rotary plates 520 coupled to the power transmitters 400, and the second link may be coupled to the other sides of the rotary plates 520 coupled to the power transmitters 400.

[0694] One of the rotary plates 520 may be equipped as the main rotary plate 521 that directly receives the power from the driver 200 or the displacement generator 300, and the remaining rotary plates 520 may be equipped to receive the power from the main rotary plate 521 via the first link 621 and the second link 622.

[0695] The rotary plate 520 and the plurality of links 620 may be coupled to each other via the rivet 524.

[0696] When the power transmitters 400 are positioned at the correct locations, the clothes hangers 900 may be directed in the front and rear direction and may be positioned parallel to each other, and the rivet 524 coupled to the first link 621 and the rivet coupled to the second link 622 may be positioned to face each other.

[0697] The first link 621 and the second link 622 may reciprocate in the width direction of the inner casing.

[0698] The first link 621 may connect the respective one ends or one sides of the plurality of rotary plates 520 to each other and reciprocate in the width direction of the inner casing, and the second link 622 may connect the other ends or the other sides of the plurality of rotary plates 520 to each other and reciprocate in the width direction of the inner casing.

[0699] The first link 621 and the second link 622 may be coupled to the plurality of rotary plates 520 while being spaced apart from the centers of rotation thereof.

[0700] Therefore, when the driver 200 operates and the rotary plate 520 rotates, the first link 621 and the second link 622 may reciprocate in opposite directions.

[0701] When the driver 200 rotates the rotary rod 533 disposed on the main rotary plate 521 to the left or counterclockwise, the support shaft 410 connected to the main rotary plate 521 rotates to the left or counterclockwise.

[0702] Therefore, the hanger part 700 and the clothes hanger 900 may also rotate counterclockwise.

[0703] When the main rotary plate 521 rotates counterclockwise, the first link 621 moves to the left via the rivet 524, and the second link 622 moves to the right. In such process, the first link 621 and the second link 622 may come closer to each other.

[0704] The first link 621 rotates the auxiliary rotary plate 522 counterclockwise while moving to the left, and the second link 622 rotates the auxiliary rotary plate 522 counterclockwise while moving to the right.

[0705] Therefore, all of the power transmitters 400 connected to the auxiliary rotary plates 522 may rotate counterclockwise. As a result, all of the power transmitters 400 may rotate counterclockwise.

[0706] In such process, the power transmitter 400, the hanger part 700, and the clothes hanger 900 further rotate counterclockwise and are arranged to be biased to the right based on the front and rear direction.

[0707] When the driver 200 rotates the rotary rod 533 disposed on the main rotary plate 521 to the right or clockwise, the support shaft 410 connected to the main rotary plate 521 rotates to the right or clockwise.

[0708] Therefore, the hanger part 700 and the clothes hanger 900 may also rotate clockwise.

[0709] The main rotary plate 521 may rotate and be restored to an original location thereof, and the hanger part 700 and the clothes hanger 900 may also rotate clockwise and be restored to original locations thereof.

[0710] When the main rotary plate 521 rotates clockwise, it moves the first link 621 to the right and moves the second link 622 to the left via the rivet 524. In such process, the first link 621 and the second link 622 may gradually move apart from each other.

[0711] The first link 621 rotates the auxiliary rotary plate 522 clockwise while moving to the right, and the second link 622 rotates the auxiliary rotary plate 522 clockwise while moving to the left.

[0712] Therefore, all of the power transmitters 400 connected to the auxiliary rotary plates 522 may rotate clockwise. As a result, all of the power transmitters 400 may rotate counterclockwise.

[0713] In this regard, when the driver 200 further rotates the rotary rod 533 to the right or clockwise, the support shaft 410 connected to the main rotary plate 521 further rotates clockwise.

[0714] In such process, the first link 621 may further move to the right, and the second link 622 may further move to the left. In such process, the first link 621 and the second link 622 may become closer to each other again.

[0715] The first link 621 and the second link 622 rotate all of the auxiliary rotary plates 522 clockwise, and the power transmitters 400, the hangers 700, and the clothes hangers 900 connected to the auxiliary rotary plates 522 further rotate clockwise and are arranged to be biased to the left based on the front and rear direction.

[0716] When the rotary rod 523 repeatedly performs the reciprocating rotational motion clockwise and counterclockwise, all of the above-described processes may be repeated, and the power transmitter 400 may also perform the reciprocating rotational motion around the support shaft 410 together to remove dust from one side and the other side of the clothes hanger 900.

[0717] Because the power transmitted via the rotary rod 523 is transmitted to all of the rotary plates 520 via the plurality of links 620, the rotation of the rotary plates 520 may be accurately controlled.

[0718] In addition, the load transmitted from the rotary rod 532 may be distributed to the plurality of links 620 and transmitted to the rotary plates 520, so that the load may be prevented from being concentrated on one of the front and rear portions, or both sides of the rotary plate 520.

[0719] FIG. 32 shows a structure of a driver 200 that may allow a rotary rod 532 to perform a reciprocating rotational motion.

[0720] The rotary rod 532 may include the reciprocating lever 510 coupled to the rotary rod 532, and may perform the reciprocating rotational motion by the driver 200 that includes the eccentric shaft 310 that rotates the reciprocating lever 510.

[0721] However, a structure that may rotate the rotary rod 532 in a different manner from the structure of the driver 200 will be described below.

[0722] The driver 200 may include a horizontal motor 212 that is seated on the support part 800 and a horizontal rotation shaft 222 that is disposed on the horizontal motor to rotate, but rotates at an angle with the support shaft 410.

[0723] The horizontal rotation shaft 222 may extend in the front and rear direction and rotate.

[0724] The driver 200 may further include the transmitter 230 that may receive power of the horizontal rotation shaft 222 as it is, but may reduce an rpm thereof.

[0725] The transmitter 230 may rotate the power shaft 240 that transmits the power to the power transmitter 400.

[0726] The power shaft 240 may be disposed parallel to the horizontal rotation shaft 222, but may be rotated by the transmitter 230 when the horizontal rotation shaft 222 rotates.

[0727] Specifically, the transmitter 230 may include the transmission pulley 232 having a diameter much larger than that of the horizontal rotation shaft 222, and the belt 233 connecting the transmission pulley 232 with the horizontal rotation shaft 222.

[0728] The power shaft 240 may be coupled to the center of rotation of the transmission pulley 232, and the transmission pulley 232 and the power shaft 240 may be supported by the pulley support 234 coupled to the support part 800.

[0729] The pulley support 234 may be installed with a bearing that rotatably supports the power shaft 240.

[0730] The pulley support 234 may be formed in a shape of a tripod or the like that is seated on the support part 800 and extends upward, the transmission pulley 232 may be disposed at the rear of or in front of the pulley support 234, and a free end of the power shaft 240 may be disposed in front of or at the rear of the pulley support 234.

[0731] The moving hanger 100 may include the displacement generator 300 that may expand the rotation radius of the power shaft 240 to a predetermined radius that may allow the rotary rod 523 to perform the reciprocating rotational motion.

[0732] The displacement generator 300 may include an eccentric connector 320 that is coupled to the power shaft 240 at one end and rotates with a radius larger than that of the power shaft 240, and the rotary arm 330 that connects the other end of the eccentric connector 320 with the rotary rod 523.

[0733] The eccentric connector 320 may include a connector body 321 that is coupled to the power shaft 240, but has a free end that rotates along a predetermined trajectory, a connector hole 322 that passes through or is recessed into a distal end of the connector body 321 and allows the rotary arm 330 to be coupled thereto, and a power coupling hole 323 that is coupled to the power shaft 240 in the other surface located opposite to one surface of the connector body 321 in which the connector hole 322 is defined.

[0734] FIG. 33 shows a structure of the driver 200 in detail.

[0735] The horizontal motor 212 may rotate the horizontal rotation shaft 222.

[0736] The horizontal rotation shaft 222 may be coupled with the power pulley 231 that may rotate the belt 233 more smoothly and prevent removal of the belt 233.

[0737] The power shaft 240 may be coupled to the transmission pulley 232 and may support the pulley support 234 by extending therethrough.

[0738] The power shaft 240 and the horizontal rotation shaft 222 may be arranged in parallel with each other.

[0739] The connector 320 may be coupled to the power shaft 240 at a rear portion, and the rotary arm 330 may be coupled to a front portion of the connector 320.

[0740] The connector 320 may be coupled to the power shaft 240 to rotate integrally.

[0741] In the connector 320, the connector hole 322 coupled with the rotary arm 330 and the power coupling hole 323 coupled with the power shaft 240 may be defined to be spaced apart from each other by a predetermined length.

[0742] Therefore, when the connector 320 rotates, the connector hole 322 may rotate along a predetermined trajectory with a radius of the distance from the power coupling hole 323, and one end of the rotary arm 330 may also rotate along the predetermined trajectory.

[0743] The reciprocating rotating part 500 may further include a rod coupling portion 524 coupled to the rotary arm 330 and connecting the rotary rod 523.

[0744] The rod coupling portion 524 may rotatably support the rotary arm 330, but may be coupled to the rotary rod 523 and rotate the rotary rod 523 clockwise or counterclockwise based on the rotation of the rotary arm 330.

[0745] The rod coupling portion 524 may be made of a material having greater rigidity than the rotary rod 523, thereby rotating the rotary rod 523 while supporting the same without difficulty even when the rotary arm 330 rotates at a high rpm.

[0746] The rod coupling portion 524 may include a fixed coupling portion 5241 coupled to the rotary rod 523 to rotate the rotary rod 523, a rotary support board 5242 extending from both surfaces of the fixed coupling portion 5241 to rotatably support the rotary arm 330, and a link shaft 5243 extending through the rotary support board 5242 and the rotary arm 330 to fix the rotary arm 330 to the rotary support board 5242.

[0747] The link shaft 5243 may be directed in a horizontal direction, so that the rotary arm 330 may perform the reciprocating rotational motion in the vertical direction on the rotary support board 5242.

[0748] On the rod coupling portion 524, the rotary arm 330 may rotate in the vertical direction, and the rod coupling portion 524 may rotate in the left and right direction or clockwise / counterclockwise based on the support shaft 410 by the rotary plate 320.

[0749] The rotary arm 330 may include a coupling end 333 coupled to the connector 310, a rotary end 332 coupled to the rod coupling portion 524, and an arm body 331 that extends the coupling end and the rotary end.

[0750] The rotary support board 5242 may be formed in a shape of boards arranged on both sides of the rotary end 332, and may accommodate both surfaces of the rotary end 332 therebetween.

[0751] FIG. 34 shows an operating principle of the displacement generator.

[0752] The displacement generator 300 may rotate along a circular trajectory around the support shaft 410 or the reciprocating rotating part 500.

[0753] The reciprocating rotating part 500 may be fixed to the support shaft 410 and rotate only in the left and right direction.

[0754] Among the components of the displacement generator 300, the rotary arm 330 has one end coupled to the reciprocating rotating part 500 and the other end rotatable along the circular trajectory by the power shaft 240.

[0755] Among the components of the displacement generator 300, the eccentric connector 320 may be coupled to the power shaft 240 and may rotate a free end of the rotary arm 330 along the circular trajectory.

[0756] As a result, the rotary arm 330 may rotate along a conical trajectory when the power shaft 240 rotates.

[0757] A length of the rotary arm 330 may be greater than a length of the eccentric connector 320 or a rotation radius of the eccentric connector 320.

[0758] In this case, the rotary arm 330 may rotate more smoothly and rotate the reciprocating rotating part 500 and the power transmitter 400 in the left and right direction.

[0759] The length of the rotary arm 330 may be smaller than the rotation radius of the eccentric connector 320. In this case, a rotation angle of the rotary arm 330 becomes larger, so that the reciprocating rotating part 500 and the power transmitter 400 may perform the reciprocating rotational motion in the left and right direction more.

[0760] The connector body 321 of the connector 320 may extend in a direction different from an extension direction of the power shaft 240.

[0761] The connector body 321 may extend to one side or both sides from the power coupling hole 323 coupled with the power shaft 240. The connector body 321 may be disposed not to be parallel to the power shaft 240.

[0762] The power coupling hole 323 coupled with the power shaft 240 is defined in a rear surface of the connector body 321, so that the connector body 321 may rotate integrally with the power shaft 240.

[0763] In one example, the connector hole 322 into which the rotary arm 330 is coupled may be defined in a front surface of the connector body 321. The connector hole 322 and the power coupling hole 323 may be defined to be spaced apart from each other by a certain length. A center point of the connector hole 322 and a center point of the power coupling hole 323 may be defined to be spaced apart from each other along a length direction of the connector body 321.

[0764] As described above, the rotary arm 330 may have the coupling end 333 coupled to the power coupling hole 323 and the rotary end 332 coupled to the rotary support board 5242.

[0765] The connector 320 may further include a rotary bearing 324 coupled to the connector hole 322 to rotatably support the coupling end 333. The coupling end 333 may be formed in a pillar shape that is inserted into and fixed to the rotary bearing 324.

[0766] The rotary support board 5242 is fixed to the support rod 523 and is rotatable in a height direction or with respect to the support shaft 410 without changing a location and a vertical level thereof. Therefore, the rotary end 332 of the rotary arm 330 may be fixed in location with respect to the coupling end 333.

[0767] When the connector 320 rotates by the power shaft 240, the connector hole 332 rotates along a circular trajectory with a radius of a distance from the power coupling hole 323.

[0768] Therefore, the rotary arm 330 may rotate while the coupling end 333 draws a conical shape with respect to the rod coupling portion 524.

[0769] As the coupling end 333 rotates while drawing a circle, not only a vertical level but also a location in the left and right direction of the coupling end 333 change. The change in the vertical level of the coupling end 333 may be allowed as the rotary arm moves in the vertical direction on the rod coupling portion 524. The change in the left and right direction-location of the coupling end 333 generates a force that rotates the rod coupling portion 524 in the left and right direction.

[0770] The rod coupling portion 524 may perform the reciprocating rotational motion in the left and right direction based on the rotation of the coupling end 333, and the rotary rod 523 and the rotary plate 520 coupled to the rod coupling portion 524 may perform the reciprocating rotational motion in the left and right direction or clockwise and counterclockwise.

[0771] The connector 320 may further include the bearing 324 that rotatably supports the coupling end 333 of the rotary arm 330. The bearing 324 allows the coupling end 333 to freely rotate with respect to the connector 320, thereby ensuring that the connector 320 freely rotates together with the power shaft 240.

[0772] FIG. 35 shows a connection structure of a driver, a displacement generator, and a reciprocating rotating part in an embodiments in FIGS. 33 and 34.

[0773] (a) in FIG. 35 shows structures of the driver, the displacement generator, and the reciprocating rotating part, and (b) in FIG. 35 intuitively shows a location relationship between the displacement generator and the driver.

[0774] As described above, when an angle between the connector 320 and the arm body 331 or between the connector 320 and the power shaft 240 is freely variable, even when the arm body 331 rotates at any angle by the connector 320, the rod coupling portion 524, the rotary rod 523, and the power transmitter 400 may rotate clockwise and counterclockwise at the fixed locations without installation angles thereof being variable.

[0775] However, when a specific condition is satisfied, even when the angle between the connector 320 and the arm body 331 does not change and the angle between the connector 320 and the power shaft 240 is always fixed, the arm body 331 and the connector 320 may freely rotate 360 degrees based on the fixed rod coupling portion 524 and power shaft 240.

[0776] The rod coupling portion 524 and the power shaft 240 should be disposed at a vertical level h corresponding to each other. Alternatively, the rod coupling portion 524 should be disposed at a point parallel to the extension direction of the power shaft 240.

[0777] In other words, the center of rotation of the power shaft 240 and a center of rotation for the rod coupling portion 524 to rotate in the left and right direction do not need to coincide with each other.

[0778] In addition, the connector 320 and the arm body 331 should maintain a coupled state while forming a 90 degree angle with each other.

[0779] In one example, to maintain the angle of 90 degrees between the connector 320 and the arm body 331 coupled to each other, a length of the connector 320 and a length of the arm body 331 may be determined based on the distance between the free end of the power shaft 240 and the rod coupling portion 524. In addition, a location at which the coupling end 333 and the connector hole 322 are coupled to each other may also be determined at the same time.

[0780] As a result, when the connector 320 and the arm body 331 are maintained in the vertically connected state while the power shaft 240 and the rod coupling portion 524 or the rotary end 332 of the arm body 331 are arranged at the same vertical level, the angles between the arm body 331 and the connector 320 and between the connector 320 and the power shaft 240 may not vary, and the arm body 331 and the connector 320 may freely rotate 360 degrees.

[0781] FIG. 36 shows a process in which a displacement generator and a rotary arm in FIG. 35 continuously rotate without changing an angle at which they are connected.

[0782] Referring to (a) in FIG. 36, the driver 200 may rotate the power shaft 240 in the horizontal direction.

[0783] The rod coupling portion 524 or the rotary end 332 of the arm body 331 may be disposed on the extension direction of the power shaft 240. The rod coupling portion 524 or the rotary end 332 may be disposed at the same vertical level h as the power shaft 240.

[0784] The connector 320 and the arm body 310 may be coupled at a right angle to each other.

[0785] The arm body 310 may extend through the connector 320 and maintain the right angle with the connector 320, or may maintain the right angle with the connector 320 while the coupling end 333 is accommodated in the connector hole 332.

[0786] The power transmitter 400 or the support shaft 410 may be coupled to a lower portion of the rod coupling portion 524 and may rotate together with the rod coupling portion 524. The hanger part 700 may be disposed at the lower portion of the support shaft 410.

[0787] Based on the rotation radius of the arm body 330, the arm body 330 may be positioned at the lowest point, and the connector hole 332 of the connector 320 may also be positioned at a lower portion.

[0788] The power transmitter 400 and the hanger part 700 may be positioned to face the driver 200.

[0789] Referring to (b) in FIG. 36, when the power shaft 240 rotates counterclockwise, the connector 320 and the arm body 330 may rotate 90 degrees. The coupling end 333 may be positioned at an intermediate vertical level in the rotation trajectory and may be positioned at the leftmost location.

[0790] In this regard, the connector 320 and the arm body 330 may rotate without additionally receiving separate compressive force or tensile force while maintaining the coupled state. The rod coupling portion 524 may simply rotate to the left without varying an installation angle thereof by the rotation of the rotary arm 330. As a result, the power transmitter 400 may rotate to the left.

[0791] Referring to (c) in FIG. 36, when the power shaft 240 further rotates counterclockwise, the connector 320 and the arm body 330 may rotate 90 degrees.

[0792] In this regard, the connector 320 and the arm body 330 may rotate without additionally receiving the separate compressive force or tensile force while maintaining the coupled state.

[0793] In the arm body 330, the coupling end 333 may be disposed at the highest location.

[0794] The rod coupling portion 524 may simply rotate to the right without varying the installation angle thereof by the rotation of the rotary arm 330. As a result, the power transmitter 400 may rotate to the right. Again, the power transmitter 400 and the hanger part 700 may be disposed to face the power shaft 240.

[0795] Referring to (d) in FIG. 36, when the power shaft 240 further rotates counterclockwise, the connector 320 and the arm body 330 may rotate 90 degrees.

[0796] In this regard, the connector 320 and the arm body 330 may rotate without additionally receiving the separate compressive force or tensile force while maintaining the coupled state.

[0797] In the arm body 330, the coupling end 333 may be disposed at an intermediate location in the rotation trajectory and may be positioned at the rightmost location.

[0798] The rod coupling portion 524 may simply rotate to the right without varying the installation angle thereof by the rotation of the rotary arm 330. As a result, the power transmitter 400 may rotate to the right. Again, the power transmitter 400 and the hanger part 700 may be oriented further to the right when viewed from the front of the power shaft 240.

[0799] When the power shaft 240 rotates further, the above process may be repeated.

[0800] When the power shaft 240 rotates in an opposite direction, the above process may be performed in a reverse order.

[0801] When the rod coupling portion 524 rotates, the main rotary plate 521 may rotate, and the auxiliary rotary plates 522 may also rotate at the same time at the same angle as the reciprocating link 620 disposed on the main rotary plate 521 moves accordingly.

[0802] As a result, all of the power transmitters 400 may perform the reciprocating rotational motion.

[0803] FIG. 37 shows another embodiment of a connection structure of a displacement generator.

[0804] (a) in FIG. 37 shows structures of the driver, the displacement generator, and the reciprocating rotating part, and (b) in FIG. 37 intuitively shows a location relationship between the displacement generator and the driver.

[0805] Even when the rod coupling portion 524 rotates in the left and right direction, an angle between the support shaft 410 and the rotary plate 520 does not vary and is always maintained and fixed.

[0806] In addition, even when the power shaft 240 rotates, an angle of the power shaft 240 does not vary and is always maintained and fixed.

[0807] In such situation, when the angle between the rotary arm 330 and the connector 320 or the angle between the connector 320 and the power shaft 240 is able to vary, the rotary arm 330 may rotate while freely varying an installation angle thereof in the vertical direction and the left and right direction with respect to the rod coupling portion 524. As a result, the connector 320 and the rotary arm 330 may be freely designed based on installation conditions without being restricted in lengths, volumes, a coupling location, or a coupling angle.

[0808] To this end, the connector hole 322 of the connector 320 and the coupling end 333 may have a ball joint or ball bearing 3331 structure. Accordingly, the coupling end 333 may maintain the state of being connected to the connector 320 while freely varying an angle at which it is connected to the connector 320.

[0809] For example, the coupling end 333 may be formed as a circular end in the arm body 331, and the connector hole 332 may be defined in the arm body 331 to have a size or a volume corresponding to an outer shape of the coupling end 333.

[0810] Therefore, the coupling end 333 may freely move inside the connector hole 332 as the arm body 331 rotates. The arm body 331 and the connector 320 may repeatedly come closer to each other or move further apart from each other based on the coupling end 333.

[0811] As a result, even when the connector 320 and the arm body 331 have various lengths depending on necessity and circumstances, the power transmitter 400 may rotate in the left and right direction by rotating the rod coupling portion 524 in the left and right direction with the power shaft 240.

[0812] When necessary, the connector 320 and the power shaft 240 may be coupled to each other such that an angle therebetween may vary. For example, the free end of the power shaft 240 may be formed in a ball shape, and the power coupling hole may be defined in a shape that is coupled to the free end of the power shaft while accommodating the same therein. The power shaft 240 and the connector 320 may also be coupled to each other in the ball joint or ball bearing form to allow the angle therebetween to be varied.

[0813] As a result, a degree of freedom in the manufacturing lengths of the connector 320 and the arm body 331, a degree of freedom in the separation distance between the connector 320 and the rod coupling portion 524, and the like may be secured.

[0814] FIG. 38 shows another embodiment of a moving hanger 100.

[0815] The moving hanger 100 may have the same structure and principle of the driver 200 and the structures and principles of the power transmitter 400, the reciprocating rotating part 500, and the connector 600 as in the above-described embodiment.

[0816] Referring to (a) in FIG. 38, the power transmitter 400 may include the plurality of power transmitters arranged to be spaced apart from each other along the length direction of the support part 800, and the reciprocating rotating part 500 that rotates the power transmitter 400 may be disposed on the power transmitter 400.

[0817] The reciprocating rotating part 500 may be equipped as the rotary plate 520.

[0818] The connector 600 may be equipped as the plurality of links 620 to connect the plurality of rotary plates 520 to each other.

[0819] The displacement generator 300 may include the eccentric shaft 310 that is coupled to the power shaft 240 and rotates with a predetermined radius while drawing a trajectory larger than the rotation radius of the power shaft 240, a rod 340 that is coupled at one end to the eccentric shaft 310, and a cylinder 350 that is coupled to the rotary plate 520, rotates the rotary plate 520, and is coupled to the other end of the rod 340.

[0820] The eccentric shaft 310 may fix the rod 340 by being eccentric to one side from the rotation center of the power shaft 340.

[0821] The eccentric shaft 310 may protrude from a top surface of the power shaft 340, but may be formed in any shape as long as it may be coupled to one end of the rod 340.

[0822] The cylinder 350 may have a radius larger than the rotation radius of the eccentric shaft 310.

[0823] The cylinder 350 may be coupled to one of the plurality of rotary plates 520, and may have a diameter larger than that of the rotary plate 520.

[0824] The other end of the rod 340 may be coupled to a surface spaced apart from a center of rotation of the cylinder 350. The rod 340 may be coupled as close as possible to an outer circumferential surface of the cylinder 350 so as to rotate the cylinder 350 at a larger angle.

[0825] Referring to (b) in FIG. 38, the cylinder 350 may include a cylinder body 351 having a diameter larger than the rotation trajectories of the eccentric shaft 310 as well as the power shaft 240, and a cylinder shaft 352 disposed at a center of rotation of the cylinder body 351 and coupled to the center of rotation of the rotary plate 520.

[0826] The rotary plates 520 may be composed of the main rotary plate 521 that is coupled to the cylinder 350 and rotates, and the auxiliary rotary plates 522 that are separated from the cylinder 350 and rotate by the connector 600.

[0827] The cylinder shaft 352 may be coupled to a center of rotation of the main rotary plate 521.

[0828] The main rotary plate 521 may have the rotary rod 523 that protrudes in a shaft shape parallel to the support shaft 410, and the cylinder 350 may have the cylinder shaft 352 fixed to and coupled to the rotary rod 523.

[0829] Accordingly, when the cylinder 350 rotates, the rotary rod 523 may be rotated, and the support shaft 410 located under the main rotary plate 521 may be rotated. In addition, when the main rotary plate 521 rotates, the plurality of links 620 may rotate the auxiliary rotary plates 522 to rotate the support shafts 410 located under the auxiliary rotary plates 522.

[0830] FIG. 39 shows an operating principle of a moving hanger 100 in FIG. 38.

[0831] When the power shaft 240 rotates, the eccentric shaft 310 may rotate along a circular trajectory with an eccentric radius t1.

[0832] The rod 340 may include one end 342 of the rod coupled to the eccentric shaft 310, the other end 343 of the rod coupled to the cylinder 350, and a rod body 341 connecting the one end and the other end of the rod.

[0833] A length of the rod body 341 may be much greater than the eccentric radius t1 of the eccentric shaft 310.

[0834] The one end 342 of the rod may reciprocally move the rod body 341 and the other end 343 of the rod while rotating along the eccentric shaft 310.

[0835] The other end 343 of the rod may be rotatably coupled to a top surface of the cylinder body 351. A cylinder coupling portion 353 to which the other end 343 of the rod is coupled may be disposed on the top surface of the cylindrical body 351.

[0836] The cylinder coupling portion 353 may be disposed to be spaced apart from the center of rotation of the cylindrical body 351 by a reciprocating radius t2.

[0837] The reciprocating radius t2 may be smaller than a length of the rod body 341.

[0838] Accordingly, when one end 342 of the rod rotates along the eccentric shaft 310, the other end 343 of the rod may reciprocally move the cylinder coupling portion 353 based on the movement of the eccentric shaft 310.

[0839] As a result, the cylinder body 351 may perform the reciprocating rotational motion by an angle d based on the cylinder shaft 352, and the power transmitter 400 may reciprocally move by an angle d.

[0840] FIG. 40 shows an operating process of a moving hanger 100 in FIG. 38.

[0841] Referring to (a) in FIG. 40, the power shaft 240 rotates together with the transmitter 230. The eccentric shaft 310 may rotate along a rotation radius of the outer circumferential surface of the power shaft 240.

[0842] The eccentric shaft 310 may be disposed close to the cylinder 350 based on the power shaft 340. As a result, the rod 340 may push the cylinder coupling portion 353 away from the power shaft 240.

[0843] Referring to (b) in FIG. 40, the power shaft 240 may rotate to rotate the eccentric shaft 310 to a location farthest from the cylinder 350. As a result, the rod 340 may pull the cylinder coupling portion 353 and rotate the cylinder body 351.

[0844] When the cylinder body 351 rotates, the main rotary plate 521 may rotate, and the plurality of links 620 may move in a staggered manner to rotate the auxiliary rotary plate 522.

[0845] FIG. 41 shows another embodiment of a moving hanger 100.

[0846] It may be understood that the cylinder 350 of the displacement generator 300 in the moving hanger 100 shown in FIG. 38 is replaced with an additional rod 360.

[0847] The moving hanger 100 may have the same structure and principle of the driver 200 and the structures and principles of the power transmitter 400, the reciprocating rotating part 500, and the connector 600 as in the above-described embodiment.

[0848] The displacement generator 300 may include the rod 340 having one end that is coupled to the eccentric shaft 310 and rotates, and the additional rod 360 having one end coupled to the reciprocating rotating part 500 and the other end coupled to the other end of the rod 340.

[0849] The rod 340 coupled to the eccentric shaft 310 may be defined as a power rod 340 because it receives the power, and the additional rod 360 may be defined as a rotating rod 360 because it rotates the reciprocating rotating part 500.

[0850] The power rod 340 and the rotating rod 360 may operate like a four-bar link.

[0851] The reciprocating rotating part 500, the power transmitter 400, and the connector 600 may have the same structures as those in the moving hanger in FIG. 35.

[0852] In one example, the driver 200 may have the same structure and principle as those of the driver 200 in FIG. 34. However, the driver 200 may only have an installation location varied so as to be effectively supported by the support part 800.

[0853] The support part 800 may be disposed upward of the power transmitter 400, the reciprocating rotating part 500, and the connector 600. The power transmitter 400, the reciprocating rotating part 500, and the connector 600 may be disposed downward of the support part 800 and upward of the top surface of the inner casing 20.

[0854] The power transmitter 400, the reciprocating rotating part 500, and the connector 600 may be disposed between the support part 800 and the inner casing 20.

[0855] Accordingly, an area in which the transmitter 230 or the motor 210 may be installed may be secured on the support part 800.

[0856] Both the transmitter 230 and the motor 210 may be disposed on the support plate 810, but to secure the length of the belt 233 and expand the diameter of the transmission pulley 232, the motor 210 may be disposed on the additional plate 860 spaced apart from the support plate 810, and the transmitter 230, which receives the power from the motor 210, may be installed on the support plate 810.

[0857] The transmitter 230 disposed on the support plate 810 may be equipped with the transmission pulley 232 on the pulley support 234.

[0858] The power shaft 240 corresponding to the center of rotation of the transmission pulley 232 may be disposed on the transmission pulley 232.

[0859] The eccentric shaft 310 may be coupled with the power shaft 240 at a portion spaced apart from the center of rotation of the power shaft 240 and rotate along the inner circumferential surface of the power shaft 240.

[0860] The additional rod 360 may rotate the reciprocating rotating part 500 located at the very end to secure a rotational length of the power rod 340. The main rotary plate 521 may be equipped on a power transmitter 400 located at the very end, and the auxiliary rotary plates 522 may be equipped on the remaining power transmitters 400.

[0861] The displacement generator 300 may further include a rotary coupling shaft 370 that may be coupled to the other end 363 of the additional rod 360 and may be coupled to the rotary rod 523 through the support part 800 to rotate the rotary rod 523.

[0862] The power rod 340 includes one end 342 that is rotatably coupled to the eccentric shaft 310, the other end 343 that is coupled to the rotating rod 360, and the power rod body 341 that connects them to each other.

[0863] The rotating rod 360 may include one end 362 that is rotatably coupled to the other end 343 of the power rod, the other end 363 that rotates the rotary coupling shaft 370, and a rotating rod body 361 that connects them to each other.

[0864] FIG. 42 shows an operating principle of a moving hanger 100 in FIG. 40.

[0865] A length a2 of the power rod body 341 may be greater than a rotation radius a1 of the eccentric shaft 310.

[0866] A length a3 of the rotating rod body 361 may be set smaller than the length a2 of the power rod body 341. The length a3 of the rotating rod body 361 may be greater than the rotation radius a1 of the eccentric shaft 310.

[0867] When the power shaft 240 rotates, the eccentric shaft 310 rotates continuously. One end 342 of the power rod 340 rotates continuously with the eccentric shaft 310.

[0868] However, the other end 343 of the power rod 340 only reciprocates within a certain range d because of a length of the power rod body 341 and the other end 343 being coupled to the rotating rod 360, and is not able to rotate completely 360 degrees.

[0869] One end 362 of the rotating rod 360 may perform the reciprocating rotational motion at the certain angle d together with the other end 343 of the power rod 340.

[0870] FIG. 43 shows an operating process of a moving hanger 100 in FIG. 41.

[0871] Referring to (a) in FIG. 43, on the power shaft 240, the eccentric shaft 310 may be disposed at a location furthest from the rotation coupling shaft 370.

[0872] As a result, the power rod 340 may be coupled to the eccentric shaft 310 and pull the rotating rod 360. As a result, the rotary coupling shaft 370 may rotate counterclockwise.

[0873] Referring to (b) in FIG. 43, when the power shaft 240 rotates, the eccentric shaft 310 may be disposed closest to the rotary coupling shaft 370. As a result, the power rod 340 may be pushed in a direction in which the rotating rod 360 is positioned, and the power rod 340 may push the rotating rod 360 away from the eccentric shaft 310. As a result, the rotary coupling shaft 370 may rotate clockwise.

[0874] When the power shaft 240 continuously rotates in one direction, the process may be performed repeatedly.

[0875] As a result, the rotating rod 360 may perform the reciprocating rotational motion around the rotary coupling shaft 370 by the predetermined angle d like a handle or a lever. When the rotary coupling shaft 370 performs the reciprocating rotational motion, the power transmitter 400 located under the main rotary plate 521 may perform the reciprocating rotational motion by rotating the rotary rod 523 of the main rotary plate 521.

[0876] When the main rotary plate 521 performs the reciprocating rotational motion, the auxiliary rotary plate 522 may also perform the reciprocating rotational motion at the same time at the same angle as the main rotary plate 521 by the connector 600. The power transmitter 400 located under the auxiliary rotary plate 522 may also perform the reciprocating rotational motion.

[0877] Therefore, all of the power transmitters 400 may perform the reciprocating rotational motion by the angle d at which the rotary coupling shaft 370 performs the reciprocating rotational motion at the fixed locations based on the support shaft 410.

[0878] FIG. 44 shows another embodiment of a moving hanger 100.

[0879] A structure and a principle of the driver 200 and structures and principles of the power transmitter 400, the reciprocating rotating part 500, and the connector 600 may be the same as those in the above-described embodiment.

[0880] However, unlike other embodiments of the moving hanger, in the moving hanger 100 shown in FIG. 44, the reciprocating rotating part 500 and the connector 600 may be connected to each other by a rack and pinion structure or a gear coupling structure.

[0881] For example, the reciprocating rotating part 500 may include a rotary gear 540 that is coupled to the power transmitter 400 and rotates integrally with the power transmitter 400.

[0882] The connector 600 may include a rod gear 630 that may move by being engaged with the rotary gear 540.

[0883] The rod gear 630 may not be coupled to the rotary gear 540 via a separate fastening member, but may have one surface in contact with or being engaged with the rotary gear 540. As a result, the structures of the connector 600 and the reciprocating rotating part 500 may be simplified.

[0884] The rotary gear 540 may be coupled to an upper end of each power transmitter 400. The rotary gear 540 may be formed in a circular shape, the support shaft 410 may be coupled to a center of rotation of the rotary gear 540, and rotary gear teeth 542 may be disposed along an outer circumferential surface.

[0885] The rotary gear 540 may have a gear center hole 543 into which the support shaft 410 is coupled at a center thereof. The gear center hole 543 may be coupled to the screw thread or the like disposed on the support shaft 410.

[0886] Alternatively, the support shaft 410 may extend through the gear center hole 543, and may adhere to the rotary gear 540 as a separate fastening member is coupled thereto, so that the rotary gear 540 and the support shaft 410 may be coupled to each other. The center hole of the rotary gear 540 may be formed in a polygonal shape like a cross-sectional shape of the support shaft 410.

[0887] The rotary gear 540 may rotate when the support shaft 410 rotates, and the support shaft 410 may rotate when the rotary gear 540 rotates.

[0888] The rotary gears 540 may all have the same size and shape. Therefore, product compatibility and assembling efficiency may be improved.

[0889] The rod gear 630 may have a length to be engaged with all of the rotary gears 540. The rod gear 630 may have rod gear teeth 631 that may be engaged with the rotary gear teeth 541 at one side.

[0890] The rod gear 630 and the rotary gear 540 may both be disposed on the support part 800.

[0891] The rod gear 630 may perform a reciprocating linear motion only along the width direction of the inner casing 20. To this end, the support part 800 may further include a removal prevention step 890 disposed on the support plate 810 or the like to prevent the rod gear 630 from being removed or deviated from the rotary gear 540.

[0892] The driver 200 may directly rotate the rotary gear 540.

[0893] Specifically, the rotation shaft 220 or the power shaft 240 may directly rotate a center of rotation of the rotary gear 540 or the support shaft 410.

[0894] For example, the rotation shaft 220 and the power shaft 240 may be inserted into the gear center hole 542 of the rotation gear 540 to rotate the rotary gear 540. Alternatively, the rotation shaft 220 and the power shaft 240 may be coupled to the support shaft 410 to rotate the rotary gear 540 while rotating the support shaft 410.

[0895] The motor 210 may allow rotary gear 540 to perform the reciprocating rotational motion while allowing the transmitter 230 or the rotation shaft 220 to perform the reciprocating rotational motion at a certain angle.

[0896] When the rotary gear 540 connected to the motor 210 or the transmitter 230 rotates, the power transmitter 400 coupled to the rotary gear 540 also rotates.

[0897] In addition, when the rotary gear 540 rotates, the rod gear 630 engaged therewith may be moved, and the rod gear 630 may rotate another rotary gear 540. Accordingly, the power transmitters 400 coupled to other rotary gears 540 may also rotate.

[0898] Because the moving hanger 200 is equipped such that the driver 200 directly rotates the reciprocating rotating part 500, the displacement generator 300 that generates a greater displacement than the power shaft 240 may be omitted.

[0899] All of the embodiments of the moving hanger 100 described so far have in common that the displacement generator 300 is connected to the driver 200 to receive the power, and the displacement generator 300 transmits the power only to some of the reciprocating rotating parts 500.

[0900] The connector 600 connects the plurality of reciprocating rotating parts 500 to each other and transmit the power transmitted to some of the reciprocating rotating parts 500 that receive the power from the displacement generator 300 to the remaining reciprocating rotating parts 500.

[0901] Because of the connector 600, the plurality of reciprocating rotating parts 500 may rotate simultaneously, and as a result, the power transmitters 400, the hangers 700, and the clothes hangers 900 may all perform the reciprocating rotational motion.

[0902] In this regard, the connector 600 may connect respective portions that are spaced apart from the centers of rotation of the plurality of reciprocating rotating parts to each other. Accordingly, when the connector 600 reciprocates along the direction in which the reciprocating rotating parts 500 are arranged, because the centers of rotation of the reciprocating rotating parts 500 are spaced apart from the connector 600, the reciprocating rotating parts 500 may rotate.

[0903] However, in a moving hanger 100 of an embodiment to be described below, the connector 600 may directly receive the power from the driver 200 or the displacement generator 300 and rotate all of the reciprocating rotating parts 500.

[0904] FIG. 45 shows another embodiment of the moving hanger 100.

[0905] All of the moving hangers 100 in the above-described embodiments are equipped in such a way that the driver 200 transmits the power to some of the reciprocating rotating parts 500 respectively coupled with the power transmitters 400, and transmits the power to the remaining reciprocating rotating parts 500 via the connector 600.

[0906] That is, the power transmitted to some of the reciprocating rotating parts 500 is transmitted to the remaining reciprocating rotating parts 500 via the connector 600, so that all of the reciprocating rotating parts 500 and all of the power transmitters 400 rotate simultaneously.

[0907] However, the moving hanger 100 in the present embodiment may be equipped in such a way that the driver 200 transmits the power to the connector 600 to rotate all of the reciprocating rotating parts 500.

[0908] The driver 200 may reciprocate the connector 600 in a linear manner, and may rotate all of the reciprocating rotating parts 500 connected to the connector 600 to rotate all of the power transmitters 400.

[0909] The reciprocating rotating part 500 may include the rotary gear 540 that is coupled to the support shaft 410, rotates around the support shaft 410, and rotates together with the support shaft 410.

[0910] The number of rotary gears 540 may correspond to the number of power transmitters 400, so that the rotary gear 540 may be coupled to each support shaft 410.

[0911] The rotary gear 540 may include a rotary gear hole 542 through which the rotation shaft 410 passes and the rotary gear teeth 541 disposed along the outer circumferential surface.

[0912] The connector 600 may include the rod gear 630 that connects the plurality of rotary gears 540 to each other.

[0913] A length of the rod gear 630 may correspond to a length that may connect the plurality of rotary gears 540 to each other, and one surface of the rod gear 630 may include the rod gear teeth 631 that are engaged with the rotary gear teeth 541.

[0914] The displacement generator 300 may have the eccentric shaft 310 that passes through and is inserted into the rod gear 630. The motor 210 may rotate the transmitter 230, and the eccentric shaft 310 may rotate together with the transmitter 230.

[0915] In one example, the reciprocating rotating part 500 may further include the reciprocating lever 510 that is coupled to the support shaft 410 and rotates together with the support shaft 410. The reciprocating lever 510 may be disposed under the rotary gear 540 and support the connector 600.

[0916] Because the reciprocating lever 510 does not need to receive the power from the driver 200, it may be equipped as the auxiliary lever 512.

[0917] In one example, the connector 600 may include the removal prevention step 890 that supports one surface of the rod gear 630 to prevent the rod gear 630 from being removed from the rotary gear 540 when the rod gear 630 reciprocates by the eccentric shaft 310.

[0918] The removal prevention step 890 may be coupled to the support plate 810 or may be formed integrally with the support plate 810, and may support one surface of the rod gear 630.

[0919] FIG. 45 is an exploded perspective view of the moving hanger 100 shown in FIG. 43.

[0920] The rod gear 630 may include a gear body 631 having a length that may connect all of the rotary gears 540 to each other, a slit 632 that passes through the gear body 631 and into which the eccentric shaft 310 is inserted, and rod gear teeth 633 that are disposed on one side surface of the gear body 631 to be engaged with the rotary gear teeth 542.

[0921] The slit 632 may be defined perpendicular to a length direction of the gear body 631. The slit 632 may be defined perpendicular to a direction in which the gear body 631 reciprocates. The slit 632 may have a small width in the length direction of the gear body 631 and have a great width in the width direction of the gear body 631.

[0922] The driver 200 may include the motor 210 that rotates the rotation shaft 220 and the transmitter 230 that transmits the power of the rotation shaft 220, and the power shaft 240 may be disposed at a center of rotation of the transmitter 230. The eccentric shaft 310 may be disposed on the power shaft 240, and the eccentric shaft 310 may be inserted into the slit 632.

[0923] A diameter of a predetermined rotation trajectory of the eccentric shaft 310 may be smaller than or equal to the width of the slit 632.

[0924] FIG. 46 shows an operating principle of a moving hanger 100 shown in FIG. 43.

[0925] Referring to (a) in FIG. 46, the eccentric shaft 310 may move to the right while rotating and push the slit 632 to the right. In this regard, the rod gear 630 moves to the right (No. 1).

[0926] When the rod gear 630 moves to the right, all of the rotary gears 540 may rotate counterclockwise at the same time (No. 2). In this regard, when the reciprocating lever 510 is also equipped in addition to the rotary gear 540, the reciprocating lever 510 also rotates counterclockwise.

[0927] When the rotary gear 540 rotates counterclockwise, the support shaft 410 coupled thereto may rotate in the same manner and may rotate counterclockwise.

[0928] Referring to (b) in FIG. 46, the eccentric shaft 310 may continuously rotate in one direction and move to the left, thereby pushing the slit 632 to the left. In this regard, the rod gear 630 moves to the left (No. 1).

[0929] When the rod gear 630 moves to the left, all of the rotary gears 540 may rotate clockwise at the same time (No. 2). In this regard, when the reciprocating lever 510 is also equipped in addition to the rotary gear 540, the reciprocating lever 510 also rotates clockwise.

[0930] When the rotary gear 540 rotates clockwise, the support shaft 410 coupled thereto may rotate in the same manner and may rotate clockwise.

[0931] When the eccentric shaft 310 rotates continuously, the above process may be repeated, and the rod gear 630 may perform the linear motion in the left and right direction and be engaged with the plurality of rotary gears 540 to allow the plurality of rotary gears 540 to perform the reciprocating rotational motion simultaneously.

[0932] In such process, the eccentric shaft 310 may rotate in one direction without stopping, so that the output of the driver 200 may be completely transmitted to the rod gear 630 and the rotary gears 540.

[0933] As a result, all of the power transmitters 400 may receive sufficient torque and perform the reciprocating rotational motion in the left and right direction or clockwise / counterclockwise.

[0934] FIG. 47 shows another embodiment of a moving hanger 100.

[0935] Unlike the moving hanger 100 described above, the connector 600 may have a portion that receives the power from the driver 200 and a portion that rotates the reciprocating rotating part 500 set to be the same. In addition, the driver 200 may directly rotate the connector 600.

[0936] Referring to (a) in FIG. 47, the connector 600 may include a rack gear 640 that may move directly by the driver 200 and may rotate the reciprocating rotating part 500.

[0937] The reciprocating rotating part 500 may include the rotary gear 540 coupled to the upper portion of the power transmitter 400. The rack gear 640 may include a rack gear body 641 that may be disposed on the rotary gear 540 and may shield a portion of an upper portion of the rotary gear 540, and rack gear teeth 642 that may be disposed on a lower portion of the rack gear body 641 and may be engaged with the rotary gear teeth 541 of the rotary gear 540 and the rotation shaft 220 of the driver 200.

[0938] The rack gear teeth 642 may be disposed adjacent to one of a front surface and a rear surface of the lower portion of the rack gear body 641.

[0939] A length of the rack gear teeth 642 may be set to be equal to a length of the rack gear body 641. A width of the rack gear teeth 642 may be smaller than a width of the rack gear body 641.

[0940] Referring to (b) in FIG. 47, the rack gear teeth 642 may protrude from the lower portion of the rack gear body 641. The rack gear teeth 642 may be engaged with an upper portion of the rotary gear teeth 541.

[0941] In addition, the rack gear teeth 642 may face a side surface of the rotary gear 540 and be engaged with a side surface of the rotary gear teeth 541.

[0942] A length of the rack gear body 641 may correspond to a length that allows the rack gear teeth 642 to be engaged with all of the rotary gears 540. The width of the rack gear body 641 may be set so as to shield a portion of the rotary gear 540 or the support shaft 410 when the rack gear teeth 642 are engaged with some of the rotary gear teeth 541.

[0943] The rack gear body 641 may be seated on the rotary gear 540 and reciprocate in the left and right direction.

[0944] The driver 200 may include the horizontal motor 212 seated on the support part 800 and the rotation shaft 220 that rotates by the horizontal motor 212. A shaft gear 222 that may be engaged with the rack gear teeth 642 may be coupled to the outer circumferential surface of the rotation shaft 220.

[0945] The horizontal motor 212 may be disposed on one side of the rotary gear 540 and may be disposed at a vertical level that overlaps the rotary gear 540. In addition, both the horizontal motor 212 and the rotary gear 540 may be disposed downward of the rack gear 640.

[0946] Therefore, a height and a volume of the entire driver 200 may be reduced.

[0947] The rack gear body 641 may shield an upper portion of the horizontal motor 212. The rack gear body 641 may be supported on a top surface of the horizontal motor 212.

[0948] The reciprocating rotating part 500 may further include the reciprocating lever 510 disposed under the rotary gear 540. The reciprocating lever 510 may be coupled to the support shaft 410 to support the rotary gear 540.

[0949] The reciprocating lever 510 may have a diameter greater than a diameter of the rotary gear 540.

[0950] The reciprocating lever 510 may be coupled to the support shaft 410, but may have a length to be exposed to the outside of the rack gear 640. Therefore, the reciprocating lever 510 may hit an adjacent reciprocating rotating part 500 or the like when the rotary gear 540 rotates excessively.

[0951] Thus, the reciprocating lever 510 may limit an angular range in which the rotary gear 540 rotates or an angular range in which the rack gear 660 rotates.

[0952] That is, when the rotary gear 540 tries to rotate beyond the set angular range, the free end of the reciprocating lever 510 may be blocked by an adjacent reciprocating lever 510 or rotary gear 540, thereby preventing further rotation. As a result, collision between the clothes hangers 900 or the laundry pieces caused by the excessive rotation of the power transmitter 400 beyond the set rotation angle may be prevented.

[0953] The rotary gear 540 may rotate the reciprocating lever 510 by the rack gear 640, and the reciprocating lever 510 may rotate the support shaft 410.

[0954] FIG. 48 shows an operating principle of a moving hanger shown in FIG. 47.

[0955] Referring to (a) in FIG. 48, when the horizontal motor 212 rotates the rotation shaft 220 to the left, the rack gear teeth 641 engaged with the rotation shaft 220 move to the left. When the rack gear teeth 641 move to the left, the entire rack gear 640 moves to the left (No. 1).

[0956] In such process, the rotary gear 540 may rotate clockwise around the support shaft 410 by being engaged with the rack gear teeth 641 (No. 2).

[0957] The angle at which the rotary gear 540 rotates may increase in proportion to a length by which the rack gear 640 moves.

[0958] Referring to (b) in FIG. 48, when the horizontal motor 212 rotates the rotation shaft 220 to the right, the rack gear teeth 641 engaged with the rotation shaft 220 move to the right. When the rack gear teeth 641 move to the right, the entire rack gear 640 moves to the right (No. 1).

[0959] In such process, the rotary gear 540 may rotate counterclockwise around the support shaft 410 by being engaged with the rack gear teeth 641 (No. 2).

[0960] The angle at which the rotary gear 540 rotates may increase in proportion to the length at which the rack gear 640 moves.

[0961] When the above process is repeated, the power transmitter 400 may perform the reciprocating rotational motion clockwise and counterclockwise.

[0962] The driver 200 may alternately rotate the rotation shaft 220 clockwise and counterclockwise, and may rotate the same only when necessary, so that the angle at which the power transmitter 400 rotates may be precisely controlled.

[0963] In addition, because the displacement generator 300 having the eccentric shaft 310 or the power shaft 240 that rotates with a larger radius than the rotation shaft 220 may be omitted, the configuration of the driver 200 may be simplified.

[0964] In addition, because the rack gear 640 may exclude installation of the separate driver 200 thereon as much as possible, the volume of the entire moving hanger 100 may be reduced and ease of assembly thereof may be enhanced.

[0965] In addition, the rack gear 640 may prevent the driver 200 and the reciprocating rotating part 500 from being exposed to the outside, and may also prevent the components of the moving hanger 100 from being separated and removed in advance.

[0966] As a result, the moving hanger 100 may be equipped such that the rack gear 640 receives the power from the driver 200 and performs the reciprocating linear motion. The rack gear 640 may transmit the power of the driver 200 to the plurality of rotary gears 540.

[0967] The rack gear 540 may allow the plurality of rotary gears 540 to perform the reciprocating rotational motion while performing the reciprocating linear motion. The above power transmitter 400 may perform the reciprocating rotational motion.

[0968] FIG. 49 shows another embodiment of a moving hanger 100.

[0969] The moving hanger in FIG. 49 has almost the same configuration as the moving hanger in FIG. 44, so that a following description will focus on differences therebetween.

[0970] The moving hanger 100 may not include the displacement generator 300, and may directly rotate one of the support shafts 410 via the power shaft 240.

[0971] When the support shaft 410 is rotated, the rotary gear 540 coupled to the support shaft 410 is rotated, and the rotary gear 540 moves the rod gear 630. The rod gear 630 is supported by the removal prevention step 890, and thus is able to move linearly.

[0972] The rod gear 630 may rotate all of the rotary gears 540 that are engaged with the gear teeth 631, and thus may eventually rotate all of the support shafts 410 that are not in direct contact with the driver 200.

[0973] When the motor 210 changes the rotation direction thereof, the power shaft 240 may also change the rotation direction thereof, and as a result, the movement directions of the support shaft 410 and the rod gear 630 may be different from each other.

[0974] FIG. 50 shows another embodiment of a moving hanger 100.

[0975] The moving hanger 100 may include the hanger part 700 that hangs the laundry in the accommodating space, the power transmitter 400 that supports the hanger part 700 and allows the hanger part 700 to perform the reciprocating rotational motion, the driver 200 that provides the power to allow the power transmitter 400 to perform the reciprocating rotational motion, and the reciprocating rotating part 500 that receives the power from the driver 200 and allows the power transmitter 400 to perform the reciprocating rotational motion.

[0976] The power transmitter 400 may include the plurality of power transmitters arranged at a predetermined distance apart from each other along the length direction of the support part 800.

[0977] The moving hanger 100 may include the connector 600 that connects the plurality of power transmitters 400 to each other to rotate the power transmitters 400 simultaneously.

[0978] The driver 200 may include the motor 210 that generates the power and the rotation shaft 220 that rotates by the motor 210 to transmit the power.

[0979] The driver 200 may further include the transmitter 230 that may transmit the rotational energy as it is while lowering the rpm of the power generated from the rotation shaft 220.

[0980] The transmitter 230 may include the transmission pulley 232 that has the diameter larger than that of the rotation shaft 220 and rotates by being connected to the rotation shaft 220, and the transmission pulley 232 may have the power shaft 240 at the center of rotation thereof to rotate the power shaft 240 together with the rotation shaft 220.

[0981] The moving hanger 100 may further include the displacement generator 300 that converts the rotation of the rotation shaft 220 or the power shaft 240 in place into the displacement that may allow the reciprocating rotating part 500 to perform the reciprocating rotational motion.

[0982] In one example, the transmitter 230 may not be an essential component, and the rotation shaft 220 may be directly coupled to the displacement generator 300.

[0983] The displacement generator may include the eccentric shaft 310 that is coupled to the rotation shaft 220 or the power shaft 240 and rotates along a predetermined trajectory with a radius larger than the rotation radius of the rotation shaft 220 or the power shaft 240.

[0984] The eccentric shaft 310 may be disposed adjacent to the inner circumferential surface of the power shaft 240 by being spaced apart from the center of rotation of the power shaft 240, and may be coupled to a free end of an expansion shaft that is connected to and rotates together with the power shaft 240 and rotate with a radius much larger than the rotation radius of the power shaft 240.

[0985] The moving hanger 100 may include the support part 800 that supports at least one of the power transmitter 400, the driver 200, the displacement generator 300, and the reciprocating rotating part 500 on the inner casing 20.

[0986] The power transmitter 400 may be rotatably supported on the support part 800.

[0987] The power transmitter 400 may be rotatably supported on one of the support plate 810 and the auxiliary plate 880 or the seating plate 860 in the support part 800.

[0988] The power transmitter 400 may be rotatably supported by the support bearing 530 seated on the support plate 810.

[0989] The power transmitter 400 may include the support shaft 410 that passes through the support plate 810, is rotatably coupled to the support bearing 530, and forms the center of rotation of the power transmitter 400.

[0990] The power transmitter 400 may include the plurality of power transmitters spaced apart from each other by the predetermined distance along the length direction of the support plate 810.

[0991] The reciprocating rotating parts 500 may be respectively coupled to all of the power transmitters 400 or may be respectively extended from all of the power transmitters 400.

[0992] The moving hanger 100 may include the connector 600 that rotates the plurality of power transmitters 400 at one time or simultaneously.

[0993] The connector 600 may receive the power from the driver 200 and allow the plurality of power transmitters 400 to perform the reciprocating rotational motion at the same time and simultaneously within the same rotation angular range.

[0994] The connector 600 may connect the reciprocating rotating parts 500 to each other and may allow the plurality of power transmitters 400 to perform the reciprocating rotational motion.

[0995] The connector 600 may include a connector reciprocating body 650 coupled to the eccentric shaft 310 on the support plate 810.

[0996] The connector reciprocating body 650 may include a reciprocating body 651 having a length that may connect all of the plurality of power transmitters 400 or the plurality of reciprocating rotating parts 500 to each other, and a reciprocating body slit 652 that may extend through the reciprocating body 651 and may be connected to the eccentric shaft 310.

[0997] The reciprocating body slit 652 may be defined along a width direction of the reciprocating body 651, and a width of the reciprocating body slit 652 may be equal to or slightly larger than the diameter of the eccentric shaft 310. A length of the reciprocating body slit 652 defined along the width direction of the reciprocating body 651 may be equal to or greater than the rotation diameter of the eccentric shaft 310.

[0998] The reciprocating body 651 may extend along the direction in which the plurality of power transmitters 400 are arranged, and the reciprocating body slit 652 may be defined perpendicular to the direction in which the reciprocating body 651 extends.

[0999] The reciprocating rotating part 500 may further include a rotation induction shaft 550 that may be connected to the power transmitter 400 at a predetermined distance apart from the support shaft 410.

[1000] The rotation induction shaft 550 may extend through the support part 800 on the power transmitter 400, and may be disposed to be spaced apart from the support shaft 410 by a rotation distance.

[1001] The rotation induction shaft 550 may be disposed for each of the power transmitters 400, and may extend through the connector reciprocating body 650.

[1002] In one example, the power transmitter 400 may include the support shaft 410 and the auxiliary support part 420 that extends from the support shaft 410 and to which the hanger part 700 is coupled, similar to the embodiment described above.

[1003] The rotation induction shaft 550 may be coupled to or extended at a predetermined distance apart from the support shaft 410 above the auxiliary support part 420.

[1004] The support part 800 may also be equipped in the same manner as that in the embodiment described above. The connector reciprocating body 650 may be disposed upward of the support part 800 and perform the reciprocating rotational motion.

[1005] However, the support shaft 410 may extend through the support frame 810, but may be disposed downward of the connector reciprocating body 650. That is, the support shaft 410 does not extend through the connector reciprocating body 650.

[1006] The support shaft 410 may be rotatably supported by the support bearing 530 coupled to the shaft coupling portion 820 and be fixed to the support part 800.

[1007] However, the rotation induction shaft 550 may extend through both the support frame 810 and the connector reciprocating body 650. Accordingly, even when the rotation induction shaft 550 includes a plurality of rotation induction shafts, the plurality of rotation induction shafts may all be connected to the connector reciprocating body 650.

[1008] The distance between the support shaft 410 and the rotation induction shaft 550 may be set to be equal to or greater than the length of the reciprocating body slit 652.

[1009] The connector reciprocating body 650 may further include an arc slit 653 through which the rotation induction shaft 550 passes and that guides the movement direction or the rotation direction of the rotation induction shaft 550.

[1010] The rotation induction shaft 550 may be accommodated and disposed in the arc slit 653.

[1011] The arc slit 653 may be formed in an arc shape by being spaced apart by a rotation distance along a predetermined circumference of a rotational center point 654 corresponding to the support shaft 410.

[1012] The rotation distance may be set to be equal to the distance between the support shaft 410 and the rotation induction shaft 550.

[1013] The arc slit 653 may be defined at a location and an angle that may rotate the rotation induction shaft 550 when the reciprocating body 651 moves in the left and right direction.

[1014] For example, when the rotation induction shaft 550 is spaced apart from the support shaft 410 in the length direction of the support part 800, the arc slit 653 may be defined along the width direction of the support part 800.

[1015] When the rotation induction shaft 550 is spaced apart from the support shaft 410 in the width direction of the support part 800, the arc slit 653 may be defined along the length direction of the support part 800.

[1016] The arc slit 653 may be defined based on the rotational center point 654 over a certain angular range in which the rotation induction shaft 550 may perform the reciprocating rotational motion.

[1017] For example, the arc slit 653 may be formed in a semicircular shape.

[1018] In addition, the arc slit 653 may be formed in a semicircular arc shape such that both ends thereof form an arc with an angle greater than 90 degrees and equal to or smaller than 180 degrees based on the support shaft 410. A radius of the arc slit 653 may correspond to the rotation distance.

[1019] The support part 800 may further include the removal prevention step 890 that supports both side surfaces or a front / rear surface of the reciprocating body 651 so that the reciprocating body 651 may perform the reciprocating linear motion.

[1020] The removal prevention step 890 may protrude from the support frame 810 and fix one side surface of the reciprocating body 651.

[1021] In one example, although not shown, the support frame 810 may further include a movement slit having the same shape as the arc slit 653 at a location corresponding to the arc slit 653. The movement slit may be formed in an arc shape based on the shaft coupling portion 820. As a result, the rotation induction shaft 550 may move along the arc slit 653 without being restricted by the support frame 810.

[1022] FIG. 51 shows an operating scheme of a moving hanger 100.

[1023] Referring to (a) in FIG. 51, the power transmitters 400 may be arranged at the predetermined distance apart from each other along the width direction of the support part 800. The power transmitter 400 may be disposed at a correct location in the width direction, which is a point perpendicular to the length direction of the support part 800.

[1024] The rotation induction shaft 550 may be disposed in one of both ends of the arc slit 653.

[1025] The transmission pulley 232 may receive the power from the motor 210, and rotate the eccentric shaft 310 while rotating the power shaft 240.

[1026] The eccentric shaft 310 may be disposed at an exact center of the reciprocating body slit 652.

[1027] Referring to (b) in FIG. 51, the power shaft 240 may rotate in one direction to rotate the eccentric shaft 310.

[1028] The power shaft 240 may rotate at a certain angle to rotate the eccentric shaft 310, so that the eccentric shaft 310 may move inward from both ends of the reciprocating body slit 652.

[1029] When the reciprocating body 651 moves in one direction, the arc slit 653 also moves the reciprocating body 652 (No. 1).

[1030] As a result, the rotation induction shaft 550 may move to one of both ends of the arc slit 653 and may rotate the power transmitter 400 based on the rotational center point 654 (No. 2).

[1031] In addition, when the power shaft 240 rotates at the certain angle and thus the eccentric shaft 310 rotates to move toward both ends and then inward again, the reciprocating body 651 may move in an opposite direction, and the arc slit 653 may also move in an opposite direction.

[1032] As a result, the rotation induction shaft 550 may move to the other of both ends of the arc slit 653 and may rotate the power transmitter 400 in an opposite direction based on the rotational center point 654.

[1033] While repeating such process, the power transmitter 400 may perform the reciprocating rotational motion based on the angle formed by the arc slit 653 based on the rotational center point 654.

[1034] The eccentric shaft 310 may rotate in one direction to transmit the power of the driver 200 to the connector 600, and the connector 600 may perform the reciprocating rotational motion.

[1035] FIG. 52 shows minimum conditions for a power transmitter 400 to perform a reciprocating rotational motion.

[1036] A diameter of the rotation induction shaft 550 performing the reciprocating rotational motion with respect to the rotational center point 654 or a rotation distance L2, which is a separation distance between the arc slit 652 and the rotational center point 654, should be equal to or greater than a radius L1 of the eccentric shaft 310 rotating by the power shaft 240.

[1037] In this case, the eccentric shaft 310 may reciprocate the reciprocating body 651 in the left and right direction by repeatedly rotating once or more, and the rotation induction shaft 550 may reciprocate both ends of the arc slit 653 repeatedly.

[1038] As a result, the rotation induction shaft 550 may allow the power transmitter 400 to perform the reciprocating rotational motion, and the laundry or the clothes hanger 900 hung on the hanger part 700 may perform the reciprocating rotational motion in the left and right direction around the power transmitter 400.

[1039] The present disclosure may be modified and implemented in various forms, so that the scope of rights thereof is not limited to the above-described embodiments. Therefore, when the modified embodiment includes elements of the claims of the present disclosure, it should be considered to fall within the scope of the present disclosure.
