[0112] Certain terms used herein are for illustrative purposes only and are not intended to limit the examples provided.
[0113] For example, expressions such as "identical" and "being identical" include not only cases where the state is strictly identical, but also cases where there are differences that allow for tolerances or equivalent functionality.
[0114] In this specification, when a component is described as being "linked" or "connected" to another component, it should be understood that it may be directly linked or connected to the other component, or that other components may exist in between. Conversely, when a component is described as being "directly linked" or "directly connected" to another component, it should be understood that there are no other components in between.
[0115] Furthermore, in this specification, terms such as “includes” or “having” merely indicate the presence of features, figures, stages, operations, components, parts, or combinations thereof described in the specification, and should be understood not to preemptively exclude the possibility of the presence or addition of one or more other features, figures, stages, operations, components, parts, or combinations thereof.
[0116] For example, expressions indicating relative or absolute arrangements such as "in any direction," "along any direction," "parallel," "perpendicular," "centered," "concentric," and "coaxial" include not only cases where the arrangement is strictly defined, but also states where there is relative displacement with an angle or distance sufficient to achieve tolerance or equivalent function.
[0117] To illustrate this disclosure, the following description is based on a spatial orthogonal coordinate system with mutually orthogonal X, Y, and Z axes. Each axis direction (X-axis direction, Y-axis direction, Z-axis direction) refers to both directions in which the axis extends. When a "+" sign is placed before each axis direction (+X-axis direction, +Y-axis direction, +Z-axis direction), it refers to one of the positive directions in which the axis extends. When a "-" sign is placed before each axis direction (-X-axis direction, -Y-axis direction, -Z-axis direction), it refers to the other negative direction in which the axis extends.
[0118] The directional expressions described below, such as "forward (+Y) / backward (-Y) / left (+X) / right (-X) / up (+Z) / down (-Z)," are defined according to the XYZ coordinate axes. However, this is merely an explanation to ensure that this disclosure is clearly understandable, and it is possible to define each direction differently depending on where the reference point is set.
[0119] The use of terms such as "first," "second," and "third" preceding the components described below is intended to avoid confusion regarding the components being referred to, and is unrelated to the order, importance, or hierarchical relationship between the components.

[0121] Furthermore, in this specification, the term "and / or" includes a combination of any of the listed items or any one of the listed items. In addition, in this specification, "A or B" may include "A", "B", or "both A and B".
[0122] Figure 1 is a perspective view showing the external appearance of a garment processing apparatus 1 according to one embodiment of the present invention. The external appearance of the garment processing apparatus 1 according to one embodiment will be described with reference to Figure 1.
[0123] The cabinet 10 forms the exterior of the garment processing device 1. The cabinet 10 may be provided with a height that is longer than its width (width in the left-right direction) or depth (width in the front-back direction).
[0124] The door 20 is located at the front of the garment processing apparatus 1. The door 20 is coupled to the front of the cabinet 10. In this embodiment, the door 20 is coupled to the cabinet 10. The door 20 can be provided as an openable door. The door 20 can be hinged to the cabinet 10. The door 20 can rotate around the hinge.
[0125] <Door 20 is open, and the processing chamber 35 is open.>
[0126] Figure 2 is a perspective view showing the door 20 of a garment processing apparatus 1 according to one embodiment of the present invention in an open state. Referring to Figure 2, the interior exposed to the user when the door 20 is open will be described.
[0127] The inner case 30 forms a processing chamber 35, which is a space for storing and processing clothing. The inner case 30 is located inside the cabinet 10. The front of the inner case 30 is open to allow clothing to be inserted. The opening of the inner case 30 can be covered by the door 20.
[0128] The garment processing apparatus 1 may include a machine room 40 in which various devices are installed to supply one or more hot air or steam to the processing chamber 35, or to purify or dehumidify the outside air of the cabinet 10.
[0129] The machine room 40 can be located separately or partitioned from the inner case 30. The machine room 40 can be configured to communicate with the inner case 30. The machine room 40 can be located below the inner case 30. This allows hot air or steam with a low specific gravity to be supplied to the garment when supplied to the inner case 30.
[0130] The processing chamber 35 and the machine room 40 can be separated and partitioned by an inner case 30 which forms the bottom 30a of the processing chamber 35. Multiple openings are formed in the wall surface of the inner case 30 that defines the processing chamber 35, allowing communication with the machine room 40. In the embodiment, the multiple openings can be formed in the bottom 30a. In the embodiment, air from the processing chamber 35 can move to the machine room 40 through the various openings, and one or more of the hot air or steam generated in the machine room 40 can move to the processing chamber 35. In the embodiment, a first opening 31, a second opening 33, and a third opening 32 can be formed in the inner case 30.
[0131] The first opening 31 is a passage through which air inside the inner case 30 goes to the machine room. The first opening 31 communicates with the circulation duct 90. The second opening 33 is a passage through which air supplied from the machine room goes to the inner case 30. The second opening 33 communicates with the circulation duct 90. The third opening 32 is a passage through which steam supplied from the machine room goes to the inner case 30. The third opening 33 communicates with the steam supply unit 80, which will be described later.
[0132] The machine room 40 will be described with further reference to Figure 26. The machine room 40 includes a circulation duct 90 that forms a circulation channel 91 that draws in air from inside the inner case 30 and discharges it back into the inner case 30. The machine room 40 is provided with a circulation fan 50 that generates airflow so that air flows through the circulation channel 91. Furthermore, it may include a heat exchanger 70 positioned on the circulation duct 90 that cools and condenses the air and heats the air. The heat exchanger 70 is a moisture removal module according to one embodiment. The machine room 40 may be equipped with a heat pump system that includes a compressor connected to the heat exchanger 70 and capable of compressing a refrigerant for cooling or heating the air. If necessary, an exhaust system using a heater, a zeolite system, etc., can be applied as a moisture removal module.
[0133] The garment processing apparatus 1 further includes a steam supply unit 80. The steam supply unit 80 may be located in the machine room 40. The steam supply unit 80 can supply steam to the processing chamber 35. The steam supply unit may include a steam generator that produces steam from water. Garments placed in the processing chamber 35 can be exposed to hot air and steam to deodorize, sterilize, and remove wrinkles.
[0134] A water supply tank 51 and a drainage tank 52 can be positioned in front of the machine room 40. The water supply tank 51 is a tank that stores water for generating steam. The water supply tank 51 is fluidly connected to the steam supply unit. The water stored in the water supply tank 51 can be supplied to the steam supply unit 80. The drainage tank 52 collects water condensed in the circulation duct and processing chamber 35.
[0135] The water supply tank 51 and the drainage tank 52 can be detachably provided. This allows the user to remove and transport the water supply tank 51 and the drainage tank 52 as needed, even if the clothing processing device 1 is not installed near a water source or drain.
[0136] The control unit P can be located in the machine room 40. The control unit P can also be located in the door 20. The control unit P can control each electrical component of the garment processing device 1. The control unit P can also receive user commands from the input unit and control each electrical component of the garment processing device 1 according to the commands. In this embodiment, the input unit can be located in the door 20. The input unit may also be a personal terminal of the user that is wirelessly connected to the garment processing device 1.
[0137] Furthermore, the machine room 40 may further include a drawer 53 for storing items necessary for managing clothing. The drawer 53 may be provided so as to be retractable from the machine room 40. The inside of the drawer 53 may be provided with space for storing items such as an iron.
[0138] The upper part of the inner surface of the inner case 30 may be provided with a garment resting section 700 (see Figure 3) on which garments can be hung in the processing chamber 35. The hanger support section 700 may be fixed to the upper surface of the inner case 30.
[0139] A garment processing apparatus 1 according to one embodiment may include a hanger 900 on which garments can be hung in a processing chamber 35. The hanger 900 is configured to allow garments to be hung in an unfolded state.
[0140] The hanger 900 can be seated on the hanger support 700. The hanger 900 (see Figure 3) can be supported by the hanger support 700. The hanger 900 can be detachably attached to the hanger support 700. When clothing is hung on the hanger support 700, the clothing can be positioned in a state of floating in the air inside the processing chamber 35.
[0141] The garment processing apparatus 1 according to one embodiment shakes a hanger 900 to dislodge foreign matter, dust, and other debris from the garment hung on the hanger 900. By shaking the garment, the garment processing apparatus 1 according to one embodiment can remove foreign matter, dust, and other debris attached to the garment, and can also remove wrinkles that have formed on the garment. In order to shake the hanger 900, the hanger support part 700 can be provided in a form that reciprocates in the width direction inside the inner case 30, or reciprocates at a set angle around a rotation axis.
[0142] Figure 3 is a diagram illustrating a hanger module 100 according to a first embodiment in which the hanger 900 is reciprocated.
[0143] The hanger module 100 is positioned on top of the inner case 30. The hanger module 100 may include a drive unit 200, a displacement generation unit 300, and a power transmission unit 400.
[0144] The power transmission unit 400 is configured to swing the hanger support unit 700. The hanger support unit 700 can be provided at the bottom of the power transmission unit 400. When the power transmission unit 400 moves, the hanger support unit 700 moves, and when the hanger support unit 700 moves, the hanger 900 hung on the hanger support unit 700 swings, thereby producing the effect of shaking the clothes.
[0145] Multiple power transmission units 400 can be provided. Multiple hanger support units 700, which are coupled to the power transmission units 400, can also be provided.
[0146] The drive unit 200 provides power to operate the power transmission unit 400. The drive unit 200 can be installed so as to be exposed inside the inner case 30, as long as it can transmit power to the power transmission unit 400. However, since the drive unit 200 is configured to operate by being supplied with electrical energy, it is desirable that it be shielded from exposure to steam and hot air. In this embodiment, the drive unit 200 is positioned between the upper surface of the inner case 30 and the cabinet 10. In this embodiment, the drive unit 200 is located outside the processing chamber 35 and is therefore not exposed to steam or hot air.
[0147] The power transmission unit 400 can be positioned to penetrate the inner case 30. The power transmission unit 400 can extend into the processing chamber 35 by penetrating the upper surface of the inner case 30. The upper end of the power transmission unit 400 is positioned above the upper surface of the inner case 30. The lower end of the power transmission unit 400 is located in the processing chamber 35. Power is transmitted from the drive unit 200 to the hanger support unit 700.
[0148] In the embodiment, the garment processing apparatus 1 may further include a sealing member capable of sealing the area of the inner case 30 that is penetrated by the power transmission unit 400.
[0149] The sealing member is connected to a hole in the inner case 30 and the support portion 800 that allows the power transmission portion 400 to pass through, and may include a support bearing that rotatably supports the power transmission portion 400. The sealing member can block the outflow of air and steam supplied to the processing chamber 35.
[0150] The upper surface of the inner case 30 can support the loads of the power transmission unit 400 and the drive unit 200. Clothes are hung on the power transmission unit 400 and it moves, and the load of the drive unit 200 is also relatively heavy. Therefore, a support part 800 may be further provided on the upper surface of the inner case 30. The support part 800 supports the load of the hanger module 100, so that the hanger module 100 can be installed stably.
[0151] The support section 800 can be positioned on top of the inner case 30. The support section 800 can be coupled to and supported by the cabinet 10. The support section 800 can be made of a highly durable and deformation-resistant metal material.
[0152] The power transmission unit 400 and the drive unit 200 can be seated on the support unit 800. The power transmission unit 400 can extend through the support unit 800 into the processing chamber 35.
[0153] The drive unit 200 includes a motor that rotates the rotating shaft. The drive unit 200 can move the power transmission unit 400 by the power generated by the rotation of the rotating shaft.
[0154] If the rotating shaft simply rotates in place, it may be difficult to oscillate the power transmission unit 400 with sufficient displacement. In this embodiment, the hanger module 100 may further include a displacement generating unit 300. The displacement generating unit 300 is coupled to a rotating shaft that is rotated by a motor and generates sufficient displacement for the power transmission unit 400 to operate. The displacement generating unit 300 may be connected to or coupled to a drive unit 200. The displacement generating unit 300 may be configured to transmit power from the drive unit 200 to the power transmission unit 400. The displacement generating unit 300 may include an eccentric shaft that rotates in a trajectory larger than the diameter of the rotating shaft. Further details will be described with reference to other drawings. The displacement generating unit 300 may have any configuration that can generate displacement such that the power transmission unit 400 reciprocates within a certain range. Detailed structure will be described later.
[0155] Figure 4 shows how the hanger module 100 according to one embodiment of the present invention operates.
[0156] The hanger module 100 can be configured to reciprocate the power transmission unit 400.
[0157] The displacement generating unit 300 can directly move the power transmission unit 400, but the power transmission unit 400 can also be moved by additional configurations. The hanger module 100 causes the power transmission unit 400 to reciprocate and rotate. The power transmission unit 400 can be configured to reciprocate and vibrate clockwise or counterclockwise from a positive position, and the clothes hung on the power transmission unit 400 can also reciprocate and vibrate clockwise or counterclockwise. The power transmission unit 400 is configured to rotate by the hanger module 100, but its position may be variable to the left or right, or it may not move at all.
[0158] Even if the clothing vibrates inside the inner case 30 due to the power transmission unit 400, the movement of the center of gravity inside the inner case 30 can be restricted. Therefore, even when the hanger module 100 is operating, the vibrations generated inside the inner case 30 can be rapidly reduced, and the generation of noise can also be minimized.
[0159] The hanger module 100 may further include a reciprocating rotating unit 500 that converts continuous rotational energy generated in the drive unit 200 or the displacement generation unit 300 into reciprocating rotational motion of the power transmission unit 400.
[0160] The reciprocating rotating section 500 may be configured to connect the displacement generating section 300 and the power transmission section 400 to each other. The reciprocating rotating section 500 may be configured to connect the displacement generating section 300 and the power transmission section 400 to each other above the inner case 30. The reciprocating rotating section 500 is prevented from being exposed to the storage space 21 and is protected from damage to clothing by the reciprocating rotating section 500.
[0161] The hanger module 100 can rotate multiple power transmission units 400 as a single unit. The hanger module 100 can be configured to rotate multiple power transmission units 400 simultaneously at the same angle. It may be advantageous for rotating all power transmission units 400 if the power generated by the drive unit 200 is transmitted directly to the multiple power transmission units 400. However, if the drive unit 200 is configured to transmit power directly to each power transmission unit 400, the structure connecting the drive unit 200 to all the power transmission units 400 may become complex. Furthermore, if multiple drive units 200 are provided, or if multiple configurations are provided in which all power transmission units 400 are connected by the drive unit 200, excessive load may be applied to the inner case 30 or the support unit 800. In addition, the inconvenience of having to control multiple drive units 200 may arise. Furthermore, if the power transmitted from a single drive unit 200 is connected so that the displacement generating unit 300 and the reciprocating rotating unit 500 transmit power to all the power transmission units 400 respectively, the arrangement and structure of the displacement generating unit 300 and the reciprocating rotating unit 500 become complex, which may reduce reliability. Therefore, the hanger module 100 can be configured such that a single drive unit 200 generates power to rotate multiple power transmission units 400.
[0162] The hanger module 100 can be configured such that power generated by the drive unit 200 is preferentially transmitted to some power transmission units 400 or some reciprocating rotating units 500, while other power transmission units 400 or other reciprocating rotating units 500 receive power secondarily. For example, a reciprocating rotating unit 500 can be configured to receive power transmitted from the drive unit 200 or displacement generation unit 300 and transmit it to some power transmission units 400. In other words, by configuring the hanger module 100 to centrally transmit power generated by the drive unit 200 to one reciprocating rotating unit 500, the power transmission structure can be easily designed and power loss can be minimized.
[0163] In one embodiment, the hanger module 100 transmits power from a drive unit 200 to a single reciprocating rotating unit 500. The power transmitted from the drive unit 200 can rotate a specific power transmission unit 400 connected to the reciprocating rotating unit 500. The hanger module 100 may further include a connecting unit 600 provided to transmit power transmitted to a specific power transmission unit 400 to other power transmission units 400. For example, the connecting unit 600 may be provided to connect a plurality of power transmission units 400 to each other. As a result, when any one power transmission unit 400 rotates, the connecting unit 600 can rotate all of the plurality of power transmission units 400.
[0164] Refer to Figure 4(a). When the drive unit 200 is activated, the power transmission unit 400 can be rotated to the right by the reciprocating rotation unit 500. At this time, the power transmission unit 400 connected to the connecting unit 600 can also be rotated entirely to the right.
[0165] Refer to Figure 4(b). When the drive unit 200 is further activated, the power transmission unit 400 can be rotated to the left by the reciprocating rotation unit 500. At this time, the power transmission unit 400 connected to the connecting unit 600 can also be rotated entirely to the left.
[0166] By repeating this process, the power transmission unit 400 can rotate from side to side.
[0167] In this case, the power transmission unit 400 can be configured to rotate left and right while remaining fixed in the positive position. The power transmission unit 400 can be fixed to the support unit 800 so that no positional changes occur in the front, back, left, or right directions when it rotates. The power transmission unit 400 can be fixed so that its position does not move with respect to the vertical, front, back, and width directions. However, the power transmission unit 400 can be configured to rotate left and right with the vertical or height direction on which the power transmission unit 400 extends as the axis of rotation. As a result, when the drive unit 200 is driven, the hanger support unit 700 can oscillate back and forth with the power transmission unit 400 as the axis.
[0168] Refer to Figure 4(c). The hanger portion 900 according to this embodiment may include a hook portion 910 and a seating portion 920. The hook portion 910 is configured to sit on the hanger support portion 700. By the hook portion 910 sitting on the hanger support portion 700, the hanger portion 900 can be hung on the hanger support portion 700.
[0169] The seating portion 920 is configured for clothing to sit on. The seating portion 920 and the hook portion 910 are connected to each other. The surface of the seating portion 920 may be provided with an anti-slip portion 950 to prevent clothing from slipping. The seating portion 920 may be arranged symmetrically with respect to the hook portion 910. The hanger portion 900 can be hung on the hanger support portion 700 such that the longitudinal direction of the seating portion 920 is positioned in the front-to-back direction of the cabinet 10.
[0170] The power transmission unit 400 can be configured to reciprocate at a constant angle of less than 360 degrees while the center of rotation is fixed. When the power transmission unit 400 rotates to the left, the hanger unit 900 can rotate the left side of the seating unit 920 to the left and the right side of the seating unit 920 to the right, with the hook unit 910 as the reference point. At this time, the angle (I) of rotation of the left side of the seating unit 920 is the same as the angle (theta; θ) of rotation of the right side of the seating unit 920. The distance moved by the left side of the seating unit 920 can be the same as the distance moved by the right side of the seating unit 920.
[0171] In the hanger module 100 according to an embodiment of the present invention, the power transmission unit 400 can be moved back and forth at a faster frequency by rotating the drive unit 200 at a higher RPM. In the garment processing apparatus 1 according to an embodiment of the present invention, the drive frequency or drive cycle of the power transmission unit 400 can be adjusted according to the course by freely adjusting the RPM of the drive unit 200.
[0172] Figure 5 shows one embodiment of the hanger module 100 according to the first embodiment of the present invention.
[0173] The hanger module 100 can be configured to transmit power from the drive unit 200 to only one of the multiple power transmission units 400, and to transmit power transmitted to a specific power transmission unit 400 to the other power transmission units 400 via the connection unit 600.
[0174] The displacement generating unit 300 or the reciprocating rotating unit 500 can be configured to centrally transmit power generated by one drive unit 200 to one power transmission unit 400. The connecting unit 600 can transmit power transmitted to a specific power transmission unit 400 to all power transmission units 400. The connecting unit 600 can be configured as a rigid body and its length can be fixed. The connecting unit 600 can be configured to connect all power transmission units 400. All power transmission units 400 can rotate simultaneously in the same direction and at the same angle when the connecting unit 600 moves. The hanger module 100 can move multiple power transmission units 400 simultaneously or at the same angle at a time using one drive unit 200.
[0175] The hanger module 100 may include a drive unit 200, a reciprocating rotating unit 500, and a connecting unit 600. The drive unit 200 is fixed to the top of the inner case 30 and provides power for the power transmission unit 400 to move. Multiple reciprocating rotating units 500 are provided. Each of the multiple reciprocating rotating units 500 is coupled to each of the multiple power transmission units 400. The reciprocating rotating units 500 receive power from the drive unit 200 and rotate so that the direction of rotation repeatedly changes. The connecting unit 600 connects the multiple reciprocating rotating units 500 to each other.
[0176] The connection section 600 may include a link bar. The link bar is provided to connect multiple reciprocating rotating sections 500 and to rotate the multiple reciprocating rotating sections 500 as a whole. The connection section 600 may consist of a single unit. The connection section 600 may be provided to connect all of the power transmission sections 400. The connection section 600 can be coupled to either the front or the rear of the reciprocating rotating section 500. One or more of the displacement generating section 300 and the drive section 200 can be coupled to either the front or the remaining rear of the reciprocating rotating section 500. One or more of the displacement generating section 300 and the drive section 200 may be positioned either the front or the remaining rear of the reciprocating rotating section 500. The connection section 600 and the drive section 200 do not interfere with each other.
[0177] The connecting portion 600 can be configured to reciprocate in the width direction of the inner case 30 and rotate a plurality of reciprocating rotating portions 500.
[0178] The drive unit 200 may include a motor 210, a transmission unit 230, and a power shaft 240. The motor 210 rotates the rotating shaft 220. The power shaft 240 is provided to rotate in conjunction with the rotation of the rotating shaft 220. The transmission unit 230 connects the power shaft 240 and the rotating shaft 220 and transmits the rotational force of the rotating shaft 220 to the power shaft 240.
[0179] The motor 210 is fixed to the top of the inner case 30 and rotates the rotating shaft 220. The rotating shaft 220 is configured to rotate at a speed faster than the appropriate period for reciprocating the power transmission unit 400. Considering this, if the RPM of the rotating shaft 220 is reduced, there is a risk that the output of the motor 210 will not be transmitted to the power transmission unit 400. The transmission unit 230 can transmit the output of the rotating shaft 220 to the power transmission unit 400 as is, while reducing the RPM of the rotating shaft 220.
[0180] The transmission unit 230 is connected to the rotating shaft 220 and rotates. The transmission unit 230 has a larger diameter than the rotating shaft 220 and can rotate. The transmission unit 230 can transmit the torque of the rotating shaft 220 while rotating at a slower rate than the rotation speed of the rotating shaft 220.
[0181] The power shaft 240 can be configured to rotate via the transmission unit 230. The power shaft 240 is provided separately from the rotating shaft 220. The power shaft 240 is configured to directly transmit power to the power transmission unit 400.
[0182] The reciprocating rotating part 500 can be coupled to the power transmission part 400 and configured to rotate together with the power transmission part 400. The reciprocating rotating part 500 may include a reciprocating lever 510. The reciprocating lever 510 is coupled to the upper part of the power transmission part 400 and is configured to rotate the power transmission part 400. The rotation center of the reciprocating lever 510 can be coupled to the support shaft 410 of the power transmission part 400 (see Figure 6). The reciprocating lever 510 can be provided in the form of a rib or a rod.
[0183] The reciprocating levers 510 can be coupled to the upper ends of multiple power transmission units 400.

The reciprocating levers 510 can be configured to reciprocate at a constant angle when the transmission unit 230 is rotated by the motor 210. The power transmission unit 400 can be coupled to the rotation center of the reciprocating levers 510 and configured to rotate together with the reciprocating levers 510. Multiple reciprocating levers 510 can be arranged and connected by a connecting unit 600. The connecting unit 600 can be configured to connect one end of the multiple reciprocating levers 510. When any one of the multiple reciprocating levers 510 rotates, the connecting unit 600 moves, allowing the multiple reciprocating levers 510 to rotate simultaneously and at once.

[0188] Multiple power transmission units 400 and reciprocating rotating units 500 are provided and are arranged at a certain distance apart along the width direction of the inner case 30.
[0189] The connecting section 600 is provided to connect a plurality of power transmission sections 400 or a plurality of reciprocating rotating sections 500 to one another. The connecting section 600 may be provided to rotate the entire plurality of power transmission sections 400 or a plurality of reciprocating rotating sections 500 simultaneously.

The power pulley 231 is coupled to the vertical rotation shaft 221 and rotates with the vertical rotation shaft 221. The transmission pulley 232 is coupled to the power shaft 240 and rotates the power shaft 240. The belt 233 connects a portion of the outer circumferential surfaces of the power pulley 231 and the transmission pulley 232.
[0195] The transmission unit 230 may further include a pulley support unit 234 that rotatably supports the power shaft 240 and the transmission pulley 232. The pulley support unit 234 is configured to support the transmission pulley 232 so that it is positioned parallel to the power pulley 231. The pulley support unit 234 is seated on the support unit 800.
[0196] The power shaft 240 can be installed at one end of the main lever 511 to transmit power transmitted from the rotating shaft 220.
[0197] Figure 7 shows the coupling structure of the drive unit 200 and the displacement generating unit 300. The displacement generating unit 300 is coupled to the power shaft 240 and can transmit power. The displacement generating unit 300 is connected to the main lever 511 and can cause the main lever 511 to reciprocate around the support shaft 410. The displacement generating unit 300 may include an eccentric shaft 310 that is eccentrically coupled to the power shaft 240 and rotates at a constant radius with respect to the rotation center of the power shaft 240.
[0198] The transmission pulley 232 is disc-shaped and can be firmly coupled to the power shaft 240. The power shaft 240 may include a shaft body 241 and a shaft boss 242. The shaft body 241 is coupled to the transmission pulley 232 and extends toward the main lever 511. The shaft boss 242 is coupled to the upper end of the shaft body 241 and is fixed to the transmission pulley 232.
[0199] The pulley support portion 234 allows the transmission portion 230 to seat on the support portion 800, rotatably supporting the shaft body 241, and can also support the load of the transmission pulley 232. The pulley support portion 234 can be made of a metal material.
[0200] The displacement generating unit 300 may include an eccentric shaft 310 that is inserted into the main housing hole 5112 from the end of the power shaft 240 and is rotatable. In this embodiment, the main housing hole 5112 is provided as a hole, but it may also be formed as a groove, as it is sufficient that the power shaft 240 can be inserted into it and rotated. The eccentric shaft 310 may be configured to rotate along a trajectory with a diameter larger than the central axis of the power shaft 240.
[0201] The main body 511 can be coupled and fixed to a support shaft 410 that passes through the inner case 30 or the support section 800. The main body 511 can be configured such that its center of rotation is coupled to the support shaft 410 and one end accommodates the eccentric shaft 310. The power transmission section 400 may include the support shaft 410 and an auxiliary support section 420 extending from the support shaft 410. The auxiliary support section 420 can accommodate a portion of the support shaft 410 and can be coupled to the support shaft 410.
[0202] The support section 800 may be equipped with a support bearing 530 seated on its upper surface, which rotatably supports the support shaft 410. The main body 511 may be coupled to the upper part of the support bearing 530.

In the power transmission section 400, the support shaft 410 is equipped to support the load of the auxiliary support section 420. The support bearing 530 and the main lever 511 are equipped to support the load of the support shaft 410. The support bearing 530 and the auxiliary lever 512 are also equipped to support the load of the support shaft 410 to which they are coupled. The loads of the support bearing 530 and the reciprocating lever 510 are supported by the support section 800 via the support bearing 530. As a result, the support section 800 can support the load of the entire moving hanger 100 and be fixed to the cabinet 10.
[0203] Figure 8 shows an exploded perspective view of the hanger module 100 according to the first embodiment.
[0204] The power transmission unit 400 may include a support shaft 410 and an auxiliary support unit 420. The support shaft 410 penetrates the upper surface of the inner case 30 and is coupled to the reciprocating lever 510. The auxiliary support unit 420 is coupled to the support shaft 410 and is located in the processing chamber 35. The auxiliary support unit 420 is coupled to a hanger unit 900 or a hanger support unit 700 provided for hanging clothes.
[0205] The support shaft 410 can be provided in a cylindrical shape with a length greater than its diameter. The support shaft 410 can be easily rotated by the reciprocating lever 510. The support shaft 410 has a significantly smaller diameter than the auxiliary support portion 420, allowing it to penetrate the inner case 30 or the support portion 800 over a smaller area. This further reduces the possibility of hot air or steam being supplied from the top of the inner case 30 into the containment space leaking out.
[0206] The auxiliary support portion 420 can have a larger cross-sectional area and a longer length than the support shaft 410. The auxiliary support portion 420 can ensure the rigidity and area necessary to support and rotate the hanger support portion 700 and the hanger portion 900.
[0207] The support section 800 may include a support plate 810 through which the support shaft 410 passes and which supports the drive unit 200. The support plate 810 may be made of a metal plate to ensure rigidity and durability and may extend in the direction in which multiple power transmission units 400 are arranged. The support section 800 may include extension bodies 812 extending upward from both ends of the support plate 810, and seating bodies 813 extending from the extension bodies 812 to seat on the support frame 12, so as to form a space in which the drive unit 200 and the reciprocating rotating unit 500 seat between the inner case 30 and the top of the cabinet 10.
[0208] The support portion 800 may include a shaft penetration portion 820 through which the support shaft 410 can pass.
[0209] Multiple shaft penetration portions 820 can be provided at positions corresponding to the positions where the power transmission portion 400 is located, and can be spaced apart along the longitudinal direction of the support plate 810.
[0210] The support section 800 may further include an auxiliary plate 880 coupled to the lower part of the support plate 810. The auxiliary plate 880 may be made of a resin material and may be provided so as to accommodate a portion of the outer surface of the power transmission section 400.
[0211] The auxiliary plate 880 is positioned below the support plate 810 and may include a plurality of housing holes 882 that can rotatably accommodate the power transmission unit 400, a plurality of extension steps 883 that extend in the width direction from the housing holes 882, and a fixing plate 881 that extends from the extension steps 883, faces the support plate 810, and is coupled to and fixed to the support plate 810.
[0212] The housing hole 882 is located at the upper end of the support shaft 410 or the auxiliary support portion 420 and may be provided to prevent hot air or air from being discharged through the shaft penetration portion 820. The extension step 883 serves to distribute the load and impact transmitted to the auxiliary plate 880 and to prevent collision or interference between the housing hole 882 and the hanger portion 900.
[0213] The support portion 800 may further include a seating plate 860 that sits on the upper part of the support plate 810.
[0214] The seating plate 860 serves to support the bearing that seats on the shaft penetration portion 820, and also prevents the reciprocating lever 510 and the connecting portion 600 from colliding with or rubbing against the support plate 810.
[0215] The seating plate 860 may include a seating plate 861. The seating plate 861 sits on the upper part of the support plate 810. The seating plate 861 may have a seating hole 862 formed therein, which penetrates the seating plate 861 and is located in a region corresponding to the shaft penetration portion 820.
[0216] The reciprocating lever 510 may include a main lever 511 to which power is directly transmitted from the drive unit 200, and an auxiliary lever 512 to which power is transmitted from the main lever 511 via a connecting unit 600. The main lever 511 and the auxiliary lever 512 may be coupled to their respective support shafts 410 and configured to rotate about the support shafts 410 as the center of rotation.
[0217] The link bar 610 may include a link body 611 and a connecting hook 612. The link body 611 can seat on and connect to the main lever 511 and the auxiliary lever 512. The connecting hook 612 may protrude from the link body 611 and be rotatably mounted on the main lever 511 and the auxiliary lever 512. When the link bar 610 rotates left or right, the main lever 511 or the auxiliary lever 512 can reciprocate left or right.
[0218] The reciprocating lever 510 may further include a link bearing 513. Multiple link bearings 513 may be provided. A link bearing 513 is coupled to one end of the main lever 511 and rotatably supports the connecting hook 612. A link bearing 513 is coupled to one end of the auxiliary lever 512 and rotatably supports the connecting hook 612.
[0219] The reciprocating rotating section 500 may further include a support bearing 530 that rotatably supports a support shaft 410 or a reciprocating lever 510. The support bearing 530 can rotatably house the support shaft 410 and seat on the shaft penetration section 820. The reciprocating lever 510 may be positioned on top of the support bearing 530. The support bearings 530 may be provided in multiple stacked units and may be provided as ball bearings, oilless bearings, or bushings.
[0220] The seating plate 860 is provided to support the support bearing 530 and can be configured to block the exposure of hot air and moisture to the outer surface of the support bearing 530. The auxiliary plate 880 is also positioned below the support bearing 530 and can be configured to block the exposure of hot air and moisture to the outer surface of the support bearing 530.
[0221] Figure 9 shows the operation method of the hanger module 100 according to the first embodiment.
[0222] The main lever 511 may include a main body 5111. The main body 5111 is coupled to the support shaft 410 and to the link bar 610. The main body 5111 may include a main central hole 5115 that is coupled to the support shaft 410 and can rotate the support shaft 410. The main body 5111 may be provided so as to extend on both sides from the main central hole 5115. The main body 5111 may include a main housing hole 5112 at one end, to which power is transmitted from the drive unit 200, and a main transmission hole 5113 at the other end, to which the link bar 610 is seated and coupled.
[0223] The auxiliary lever 512 may include an auxiliary body 5121 and an auxiliary central hole 5125. The auxiliary central hole 5125 is coupled to the support shaft 410. The auxiliary body 5121 is formed to extend to one side from the auxiliary central hole 5125. The auxiliary body 5121 includes an auxiliary transmission hole 5123 that is coupled to the link bar 610. The auxiliary body 5121 may be shorter in length than the main body 5111.
[0224] The distance from the main central hole 5115 to the main transmission hole 5113 can be set to be the same as the distance from the auxiliary central hole 5125 to the auxiliary transmission hole 5123. The link bar 610 is seated above the auxiliary transmission hole 5123 and the main transmission hole 5113 and can connect the auxiliary lever 512 and the main lever 511 to each other.
[0225] Refer to Figure 9(b). The drive unit 200 can be configured such that the power shaft 240 is inserted into the main housing hole 5112. This allows the power shaft 240 to be rotated directly to rotate the main housing hole 5112 from side to side.
[0226] The eccentric shaft 310 is housed in the main housing hole 5112. The diameter of the eccentric shaft 310 can be set to be smaller than the diameter or width of the main housing hole 5112. This allows the eccentric shaft 310 to be inserted into and supported in the main housing hole 5112. The constant radius over which the eccentric shaft 310 rotates can be set to be larger than the width or diameter of the main housing hole 5112. As a result, when the eccentric shaft 310 rotates, the main housing hole 5112 is pushed by the eccentric shaft 310 and can move left and right with respect to the main central hole 5115.
[0227] When the eccentric shaft 310 rotates in a certain direction, the main housing hole 5112 of the main body 511 also reciprocates in a certain direction. As a result, the central hole 5115 of the main body 511 also rotates in the same direction as the main housing hole 5112, and the main transmission hole 5113 can reciprocate in the opposite direction to the certain direction.
[0228] When the eccentric shaft 310 rotates, the support shaft 410 reciprocates together with the main central hole 5115, causing the power transmission unit 400 to reciprocate. The main transmission hole 5113 also reciprocates, causing the link bar 610 to move back and forth, so that the auxiliary lever 512 can also reciprocate around the auxiliary central hole 5125 and the support shaft 410. The power transmission unit 400 connected to the auxiliary lever 512 can also reciprocate.
[0229] The power transmission section 400 can have a spiral formed along the upper periphery of the support shaft 410. The main transmission hole 5113 and the auxiliary central hole 5125 can be directly connected and fixed to the support shaft 410 using a spiral or the like.
[0230] The power transmission unit 400 may further include a transmission coupling unit 415 that is coupled to the helix of the support shaft 410 so as to fix the support shaft 410 to the main transmission hole 5113 and the auxiliary central hole 5125 after the support shaft 410 has passed straight through the main transmission hole 5113 and the auxiliary central hole 5125. The transmission coupling unit 415 connects the support shaft 410 and the reciprocating lever 510, allowing the support shaft 410 and the reciprocating lever 510 to rotate simultaneously.
[0231] Figure 10 is an additional diagram illustrating the process by which the reciprocating rotating part 500 rotates back and forth.
[0232] As shown in Figure 10(b), the eccentric shaft 310 is positioned at position I and can be located at one end or the other end of the main housing hole 5112. Subsequently, when the power shaft 240 rotates 90 degrees clockwise, the eccentric shaft 310 is separated by 1 / 2R from the rotation center of the power shaft 240, so the eccentric shaft 310 can move 1 / 2R to the right. The main housing hole 5112 also moves to the right, causing the main body 5111 to rotate the support shaft 410 clockwise. As a result, the power transmission unit 400 coupled to the main lever 511 rotates clockwise, and the hanger support unit 700 coupled to the power transmission unit 400 and the hanger unit 900 hung on the hanger support unit 700 also rotate clockwise. Therefore, the clothing also rotates clockwise.
[0233] Meanwhile, the main transmission hole 5113 moves in the opposite direction to the main housing hole 5112 around the support shaft 410, moving to the left. As a result, the connecting part 600 also moves to the left, and by moving all the auxiliary levers 512 connected to the connecting part 600 to the left, all the power transmission parts 400 connected to the auxiliary levers 512 can be rotated clockwise.
[0234] Subsequently, when the eccentric shaft 310 rotates 90 degrees, it is positioned in position III, and when it rotates 180 degrees, it is positioned in position IV. During this process, the main storage 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 can move from state (b) to state (a). During this process, the power transmission unit 400 connected to the main lever 511 rotates clockwise, and the hanger support unit 700 connected to the power transmission unit 400 and the hanger unit 900 hung on the hanger support unit 700 also rotate counterclockwise. Therefore, the clothing also rotates counterclockwise.
[0235] Meanwhile, the main transmission hole 5113 moves in the opposite direction to the main housing hole 5112 around the support shaft 410, moving to the right. As a result, the connecting part 600 also moves to the right, and by moving all the auxiliary levers 512 connected to the connecting part 600 to the left, all the power transmission parts 400 connected to the auxiliary levers 512 can be rotated counterclockwise.
[0236] When the power shaft 240 rotates continuously clockwise, the eccentric shaft 310 also rotates continuously, allowing the aforementioned process to be repeated infinitely. When the power shaft 240 rotates continuously counterclockwise, the eccentric shaft 310 also rotates continuously counterclockwise, allowing the aforementioned process to be repeated infinitely in reverse order. As a result, the clothing can swing from side to side around the support shaft 410 of the power transmission unit 400 on which it is hung.
[0237] Figure 11 is a schematic diagram showing the movement of the hanger 900 by the hanger module 100 according to the first embodiment.
[0238] The hanger module 100 according to the first embodiment causes the hanger 900 to reciprocate within a set angle (θ) with the central part 901 as the center O. According to the first embodiment, the hanger 900 moves back and forth from the first position P1 to the second position P2, and from the second position P2 to the first position P1. Since the hanger 900 is seated on the hanger support part 700, the position of the hanger support part 700 (see Figure 4) that positions the hanger 900 at the first position P1 is defined as the first position, and the position of the hanger support part 700 (see Figure 4) that positions the hanger 900 at the second position P2 is defined as the second position. According to the first embodiment, the garment hung on the hanger 900 experiences different displacements at the central part 901 and the end part 902. According to the embodiment, the minimum displacement occurs at the central part 901, and the displacement at the central part 901 is Xmin. Xmin may be 0. The maximum displacement occurs at the end 902, and the displacement at the end is Xmax. When moving from the first position P1 to the second position P2, the maximum displacement Xmax occurs at the end 902 of the hanger 900. The minimum displacement Xmin occurs at the center of rotation 901 of the hanger. In other words, the displacement that occurs differs depending on the position of the hanger 900 while moving from the first position P1 to the second position P2. Since the force transmitted to the clothing is proportional to the acceleration, the force transmitted on the end 902 side is greater than the force transmitted on the central part 901 side. Therefore, in the first embodiment, the force transmitted to the clothing is defined as the reference displacement Xref, which is the displacement at the reference part 903, which is located midway between the end 902, where the maximum displacement occurs, and the central part 901, where the minimum displacement occurs.
[0239] According to the first embodiment, the force generated in clothing can be defined by the following mathematical formula.
[0240]
number
[0241] Figure 12 shows a hanger module 100' according to a second embodiment of the present invention.
[0242] The hanger module 100' may include a support bar 120', a hanger support section 700', and a drive section 400'.
[0243] The drive unit 400' may include a motor 451' fixed to the top of the support bar 120' that rotates the rotating shaft 453'. It may also include an eccentric shaft 455' coupled to the rotating shaft 453' that rotates in a trajectory larger than the rotation radius of the rotating shaft 453'.
[0244] A reciprocating guide unit 500' can be provided in the center of the support bar 120' to house an eccentric shaft 455' and transmit power. The eccentric shaft 455' can be configured to move in accordance with the rotation of the rotating shaft 453' while coupled to the reciprocating guide unit 500', causing the reciprocating guide unit 500' to move back and forth. The eccentric shaft 455' can be configured to rotate while coupled to the end of a connecting shaft 452' which is coupled to the end of the rotating shaft 453'.
[0245] Figure 13 shows a structure in which the support bar 120' of the hanger module 100' according to the second embodiment moves from side to side.
[0246] The reciprocating guide section 500' is formed in the thickness direction of the support bar 120' and may include a slit 541' for accommodating the eccentric shaft 455'.
[0247] Refer to Figure 13(a). The eccentric shaft 455' can be inserted into the slit 541' and configured to rotate while tracing an arc trajectory with radius R, a distance from the rotation axis 453'. The support bar 120' can be fixed in the garment processing apparatus 1 so as to be movable only in the left-right direction, and not movable forward or backward.
[0248] Refer to Figure 13(b). When the eccentric axis 455' rotates 90 degrees to the right, the slit 541' can move along with the eccentric axis 455' by R to the right, as the eccentric axis 455' moves by R to the right. As a result, the support bar 120' moves to the right.
[0249] Thus, when the eccentric shaft 455' rotates 180 degrees to the left, the slit 541' moves to the left, and the support bar 120' also moves to the left. When the rotating shaft 453' rotates once, the support bar 120' can move back and forth once, and when the rotating shaft 453' rotates continuously, the support bar 120' will move back and forth multiple times. A hanger 900 can be hung on the hanger support section 700'. When clothing is hung on the hanger support section 700', foreign matter and dust can be separated by vibration from side to side.
[0250] Figure 14 is a schematic diagram showing the movement of the hanger 900 by the hanger module 100' according to the second embodiment.
[0251] The hanger module 100' according to the second embodiment moves the hanger 900 back and forth from a first position P1 to a second position P2. The first position P1 is a position moved to the right from the reference position P0. The second position P2 is a position moved to the left from the reference position P0. The first position P1 is the maximum displacement in the right direction, and the second position P2 is the maximum displacement in the left direction.
[0252] According to the second embodiment, when moving from the first position P1 to the second position P2, the displacement of the hanger 900 at all positions is the same in X.
[0253] The force generated on the clothing according to the second embodiment can be defined by the following formula.
[0254]
number
[0255] Considering the spatial constraints of the garment processing apparatus 1 and issues such as collisions between garments, the maximum displacement of the hanger is limited. Therefore, Xmax, the maximum displacement in the first embodiment, and X, the maximum displacement in the second embodiment, may be substantially the same. In the embodiments, Xmax and X may be 25 mm to 85 mm, preferably 28 mm to 84 mm, and more preferably 50 mm to 60 mm.
[0256] Considering that the force transmitted to the clothing in the apparatus according to the first embodiment is Xref and not Xmax, the hanger module 100 according to the first embodiment is required to move at a higher frequency than the hanger module 100' according to the second embodiment.
[0257] <Method for driving a hanger module according to an embodiment of the present invention>
[0258] According to an embodiment of the present invention, clothing is processed by moving the hanger 900 back and forth from a first position P1 to a second position P2. The reciprocating speed can be defined in terms of frequency. The frequency can be defined in rpm. rpm can be the number of reciprocations per minute. According to the embodiment, when the rotating shaft 220 of the motor 210 rotates once, the hanger 900 moves from the first position P1 to the second position P2 and then returns to the first position P1, so the rpm of the motor 210 can be the same as the rpm of the hanger 900.
[0259] The control unit P can control the rpm of the hanger 900. In this embodiment, the control unit P can control the rpm of the hanger 900 by controlling the rotational speed of the motor. The hanger 900 can move at a normal frequency. In this embodiment, the normal frequency can be defined based on the following description.
[0260] <Reference frequency>
[0261] Figure 15 is a diagram illustrating the range of frequencies defined as the reference frequency, and shows the recorded lateral behavior of sample M.
[0262] Refer to Figure 15. Sample M is hanging on a hanger 900 inside the garment processing device 1. The behavior of sample M forms a waveform. Sample M is a cotton fabric with dimensions of 20 × 90 cm (width × length) and a weight of 151 g / m2. At the reference frequency, in the waveform following the behavior of sample M, there are two superposition points of the first waveform W1 when the sample is biased to one side and the second waveform W2 when it is biased to the other side. When two superposition points occur, the amplitude of the garment is sufficiently secured, and the processing efficiency is high. When there are three superposition points, the amplitude of the garment does not become larger than in the case of two, but excessive impact is applied when the garment is moistened, which may cause deformation of the garment. In the embodiment of the present invention, the frequency range in which the number of superposition points of the two outermost waveforms formed according to the behavior of sample M is two is defined as the reference frequency. According to the second embodiment, the reference frequency is 200 rpm to 250 rpm.
[0263] Figure 16 shows the behavior of sample M according to the frequency.
[0264] Refer to Figure 16. From left to right, the sample M is moved at higher frequencies. The range where there are two superposition points is defined as the normal frequency. At frequencies lower than the normal frequency, there is one superposition point. At frequencies lower than the normal frequency, there may be no superposition points at all. At frequencies higher than the normal frequency, there are three superposition points, and more may occur.
[0265] Figure 17 shows the behavior of hemp, cotton, and silk samples based on the results of excitation at the standard frequency.
[0266] The size of each sample is the same, 20×90 cm (width × length). In the experimental example, when a cotton sample is excited at the reference frequency, two superposition points are generated. When a linen sample is excited at the same reference frequency, two superposition points are generated. When a silk sample is excited at the same reference frequency, three superposition points are generated.
[0267] Figure 18 shows the behavior of linen samples, cotton samples, and silk samples based on the results of excitation at a low frequency that is lower than the reference frequency.
[0268] In the experimental example, the low frequency is a frequency at which one superposition point is generated when a cotton sample is excited. When a linen sample is excited at the same low frequency, zero superposition points are generated. When a silk sample is excited at the same low frequency, two superposition points are generated.
[0269] As can be confirmed from the experimental examples in Figure 17 and Figure 18, a fabric with better drapability (more flexible) tends to have a greater number of superposition points at the same rpm. As the number of superposition points increases, the size of the bulges (thick portions of the waveform) formed decreases, so the force concentration also changes.
[0270] <Improvement of clothing treatment efficiency through variable frequency control>
[0271] According to an embodiment of the present invention, the frequency for exciting clothing can be variably controlled, and the variable control of frequency can improve clothing treatment efficiency. The frequency applied to clothing by the hanger modules 100, 100' can be varied within the frequency range referenced with reference to Figure 19.
[0272] The first frequency, which is the lowest frequency, may be a frequency in a range where at least one superposition point is generated for a silk sample. The first frequency may be 40% or more of the reference frequency.
[0273] The reference frequency is referred to as the fourth frequency.
[0274] The sixth frequency, which is the highest frequency, may be the frequency at which the motor is at its maximum output. The maximum output of the motor can be set taking into account the noise caused by the vibration of the motor itself and the vibration of the clothing processing device 1.
[0275] According to the moving hanger 100 of the first embodiment, the first frequency may be 120 rpm, the second frequency 150 rpm, the third frequency 200 rpm, the fourth frequency 250 rpm, the fifth frequency 300 rpm, and the sixth frequency 350 rpm.
[0276] According to the moving hanger 100' of the second embodiment, the first frequency may be 80 rpm, the second frequency 110 rpm, the third frequency 150 rpm, the fourth frequency 180 rpm, the fifth frequency 210 rpm, and the sixth frequency 250 rpm.
[0277] In the first embodiment, the first frequency is 120 rpm and the sixth frequency is 350 rpm, resulting in a difference of 230 rpm. Because the frequency range is wide, even just by varying the frequency, more precise garment processing is possible than in the second embodiment, and high garment processing performance can be expected.
[0278] Referring to Figure 20, six motion modes provided by the garment processing apparatus 1 according to one embodiment of the present invention will be described.
[0279] The motion mode is a control method by which the hanger module 100 vibrates the clothing. Each motion mode vibrates the clothing using a different frequency from the others.
[0280] The first motion mode is a mode in which clothing is vibrated at the standard frequency, which is the fourth frequency. While operating in the first motion mode, the frequency does not change from the fourth frequency. The first motion mode is the standard mode for handling all clothing except for garments that require delicate handling.
[0281] The second motion mode is a mode in which the clothing is vibrated at the sixth frequency. While driven in the second motion mode, the frequency does not change from the sixth frequency. The second motion mode is a mode that can use the maximum output of the motor to shake the clothing at the maximum frequency, allowing dust to be shaken off the clothing.
[0282] The third motion mode is a mode in which the frequency is variable within a frequency range below the reference frequency. In the embodiment, the frequency can be varied while oscillating between the first to third frequencies during one variable period. The third motion mode will be further explained with reference to Figure 21. In the third motion mode, the frequency is varied by oscillating between a first frequency above the lowest frequency, a second frequency greater than the first frequency, and a third frequency greater than the second frequency and below the fourth frequency. The third motion mode can include a first interval during one variable period (t0~t6:T1) in which the frequency is varied from the first to the third frequency during the first time (t0~t2), and a second interval during a second time (t2~t3) which is shorter than the first time, in which the frequency is varied from the third frequency to the first frequency. According to the third motion mode, when various types of clothing are dried together, air can pass uniformly between the clothes. That is, when the third motion mode is applied to the section in which the moisture content of the clothes is reduced, the drying efficiency of the clothes can be increased. In this embodiment, the hanger module 100 can be driven in a third motion mode during the drying process. The variable frequency period can be set to 20 seconds to 1 minute. If the variable period is less than 20 seconds, the desired vibration may not be transmitted to the clothing. If the variable period exceeds 1 minute, the vibration frequency may not change sufficiently within the limited process time. However, the variable frequency period can be changed according to the design specifications.
[0283] The fourth motion mode is a mode in which the frequency is varied within a frequency range above the reference frequency. In the embodiment, the frequency can be varied while oscillating between the fourth frequency and the sixth frequency during one variable period. The fourth motion mode will be further described with reference to Figure 22. In the fourth motion mode, the frequency is varied by oscillating between a frequency above the reference frequency (fourth frequency in the embodiment), a fifth frequency greater than the fourth frequency, and a frequency greater than the fifth frequency and less than or equal to the sixth frequency (sixth frequency in the embodiment). The fourth motion mode may include a first interval in which the frequency is varied from the fourth frequency to the sixth frequency during the first time (t0 to t2) of one variable period (t0 to t6: T1), and a second interval in which the frequency is varied from the sixth frequency to the fourth frequency during the second time (t2 to t3), which is shorter than the first time. According to the fourth motion mode, it is possible to change the position of the superposition point associated with the wave motion of the clothing and improve the wrinkle removal performance. The fourth motion mode can be applied to sections where wrinkle removal is required. The fourth motion mode can be applied to sections where the humidity level increases. When the fourth motion mode is applied, uniform wrinkle removal performance can be obtained.
[0284] The fifth motion mode is a mode in which clothing is vibrated at the first frequency. While driven in the fifth motion mode, the frequency does not change from the first frequency. The fifth motion mode is a mode for handling easily stretchable knitwear and blouses that are easily damaged. According to the fifth motion mode, stretching of knitwear can be prevented and hanger marks can be prevented from occurring on clothing.
[0285] The sixth motion mode is a mode in which the garment is vibrated at the second frequency. While driven in the sixth motion mode, the frequency does not change from the second frequency. The sixth motion mode provides a force that returns the disarrayed garment to its original position. At the end of the process, the hanger module 100 can operate in the sixth motion mode.
[0286] Figure 23 is a diagram illustrating the driving state of each component of each process according to one embodiment of the present invention.
[0287] The garment processing apparatus 1 according to the embodiment can provide five steps. The garment processing apparatus 1 may include a pre-steam step, a pre-heat step, a steam step, a stay step, and a drying step.
[0288] The pre-steam process is a process in which water is heated to generate steam. During the pre-steam process, the circulation fan operates (turns on) while steam is being generated, allowing the air inside the processing chamber 35 to circulate. At this time, the heat pump is kept in a non-operating (off) state.
[0289] The preheating process is a process of preheating the inside of the processing chamber 35. In the preheating process, the heat pump is activated (turned on) to heat the air inside the processing chamber 35. Steam can be supplied to the processing chamber 35 during the preheating process. During the preheating process, the circulation fan is activated (turned on) to circulate the air inside the processing chamber 35. The moisture content of the clothing can increase while the preheating process is underway.
[0290] The steam process is a process that supplies steam to the garments to increase their moisture content. During the steam process, steam can be supplied to the processing chamber 35. During the steam process, the circulation fan operates (turns on), allowing the air inside the processing chamber 35 to circulate. As the steam process progresses, the moisture content of the garments can increase. At this time, the heat pump is kept in a non-operating (off) state.
[0291] The Stay step is a step of maintaining the moisture-containing state of clothes. No more steam is supplied during the Stay step. During the Stay step, the circulation fan operates (is turned on), allowing air inside the processing chamber 35 to circulate. At this time, the heat pump is kept in a non-operating (off) state. The Stay step is a step in which no more steam is supplied, and no moisture removal driving is performed by the moisture removal module. While the Stay step proceeds, the moisture content of the clothes can be maintained. While the Stay step proceeds, the moisture content of the clothes may also increase or decrease.
[0292] The Drying step is a step of drying clothes. The heat pump is driven during the Drying step. The heat pump removes moisture from the air in the processing chamber 35. During the Drying step, the circulation fan operates (is turned on), allowing air inside the processing chamber 35 to circulate. While the moist air in the processing chamber 35 circulates in the circulation duct via the circulation fan, moisture is removed therefrom by the heat pump. While the Drying step proceeds, the moisture content of the clothes decreases.
[0293] The clothes treatment apparatus 1 provides various treatment courses. A treatment course is configured by combining one or more of a PreSteam step, a PreHeat step, a Steam step, a Stay step and a Drying step.
[0294] While the PreSteam step, PreHeat step, Steam step, Stay step and Drying step proceed, the hanger modules 100, 100' can be driven in the first to sixth motion modes.
[0295] Figure 24 is a diagram showing an example of a treatment course provided by the clothes treatment apparatus 1 and the motion modes of the hanger module in each step.
[0296] The standard styling course sequentially performs the following steps: PreSteam, PreHeat, Steam, Stay, and Drying. During the PreSteam process, hanger modules 100 and 100' are driven in second motion mode. During the PreHeat process, hanger modules 100 and 100' are driven in fourth motion mode. During the Steam process, hanger modules 100 and 100' are driven in fourth motion mode. During the Stay process, hanger modules 100 and 100' are driven in second motion mode. During the Drying process, hanger modules 100 and 100' are driven in first motion mode. According to the standard styling course of this embodiment, wrinkles can be effectively removed because the garment is vibrated in fourth motion mode while its moisture content increases.
[0297] The wool / knit styling course can sequentially perform the following steps: PreSteam, PreHeat, Steam, Stay, and Drying. During the PreSteam, PreHeat, Steam, and Stay processes, the hanger modules 100 and 100' are not driven. During the drying process, the hanger modules 100 and 100' are driven in fifth motion mode. According to the wool / knit styling course of this embodiment, since the garment is vibrated in fifth motion mode while its moisture content is decreasing, damage such as stretching of the garment can be prevented.
[0298] The silk styling course can sequentially perform the pre-steam, steam, stay, and drying processes. While the pre-steam, steam, stay, and drying processes are in progress, the hanger modules 100, 100' are driven in sixth motion mode. According to the silk styling course of this embodiment, it is possible to increase the processing efficiency of silk while minimizing damage to the silk.
[0299] In an embodiment not shown in the figures, the device can move at a frequency below the reference frequency during the stay process. For example, it can be driven in a third motion mode, a fifth motion mode, or a sixth motion mode that operates at a frequency below the reference frequency.
[0300] In an embodiment not shown, the hanger modules 100, 100' can be driven in a third motion mode while the Stay and / or Drying processes are underway after the steaming process. According to the third motion mode, when processing various garments together, air can be evenly distributed between the garments. That is, the third motion mode can improve the efficiency of garment processing when applied while the circulating fan is running to allow air to circulate. When driven in the third motion mode during the Stay process, the moisture content of the garments can be made more uniform. When driven in the third motion mode during the Drying process, the drying efficiency of the garments can be improved.
[0301] Figure 25 shows an example of a processing course for the garment processing apparatus 1 and the motion modes of the hanger module for each drying process.
[0302] The standard drying course drives hanger modules 100 and 100' in first motion mode as the drying process progresses.
[0303] The delicate low-temperature drying course drives hanger modules 100 and 100' in fifth motion mode as the drying process progresses. In the delicate low-temperature drying course, the garments are vibrated at the slowest speed to minimize damage to the garments.
[0304] The Time Dry course drives hanger modules 100 and 100' in sixth motion mode as the drying process progresses. The Time Dry course vibrates the clothes at a frequency lower than the standard frequency to minimize damage to the clothes, while improving processing speed by vibrating the clothes at a higher frequency than the Delicate Low Temperature Dry course. The sixth motion mode allows disarrayed clothes to move back to their original positions and straighten the clothes.
[0305] The heavy padding drying course drives hanger modules 100 and 100' in fifth motion mode as the drying process progresses. The heavy padding drying course vibrates the garment at the slowest speed to keep the padding fluffy.
[0306] The combined clothes drying course drives hanger modules 100 and 100' in third motion mode during the drying process. According to the combined clothes drying course, air can circulate evenly between the garments, improving drying uniformity when drying multiple garments.
[0307] In the first to sixth motion modes, the amplitude corresponding to the displacement following the reciprocating motion of the hanger support parts 700 and 700' is the same. In the first embodiment, Xmin, Xmax, and Xref, referenced in Figure 11, are all the same for the first to sixth frequencies and are the same for the first to sixth motion modes. In the second embodiment, X, referenced in Figure 14, is all the same for the first to sixth frequencies and is the same for the first to sixth motion modes. Because the amplitude is the same, the vibration noise of the garment processing device 1 is relatively constant, and because the frequency can be varied, garment processing efficiency such as wrinkle removal performance, brushing performance, and drying performance can be improved.
