[0120] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the attached drawings. The configuration of the device and the control method described below are only intended to illustrate embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. Reference numerals used throughout the specification represent identical components.

[0121] Certain terms used in this specification are for convenience of explanation only and are not intended to limit the illustrated embodiments.

[0122] For example, expressions such as "same" and "same as" not only indicate a strictly identical state, but also indicate a state in which there is a difference in tolerance, or the degree to which the same function is obtained.

[0123] In this specification, when a component is referred to as being "connected" or "connected" to another component, it should be understood that it may be directly connected or connected to that other component, but that there may be other components in between. Conversely, when this specification refers to a component as being "directly connected" or "directly connected" to another component, it should be understood that there are no other components in between.

[0124] In this specification, it should be understood that terms such as “include” or “have” are intended to specify only the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, and do not preclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0125] For example, expressions indicating relative or absolute arrangements such as “in which direction,” “along which direction,” “parallel,” “perpendicular,” “centered,” “concentric,” or “coaxial” not only strictly indicate such arrangements, but also indicate a state of relative displacement with an angle or distance that allows for tolerance, or the degree to which the same function is obtained.

[0126] In order to explain the present disclosure, the following description is based on a spatial orthogonal coordinate system with an X-axis, a Y-axis, and a Z-axis that are orthogonal to each other. Each axis direction (X-axis direction, Y-axis direction, Z-axis direction) means both directions in which each axis extends.

[0147] A clothes hanger support member (700, see Fig. 3) capable of holding clothes in a processing chamber (35) may be provided on the upper part of the inner surface of the inner case (30). The clothes hanger support member (700) may be fixed to the upper surface of the inner case (30).

[0148] A garment treatment device (1) according to one embodiment may include a hanger (900) capable of placing garments in a treatment chamber (35). The hanger (900) is configured to hang garments in an unfolded state.

[0149] The hanger (900) can be mounted on the hanger support member (700). The hanger (900, see FIG. 3) can be supported on the hanger support member (700). The hanger (900) can be detachably mounted on the hanger support member (700). When clothing is placed on the hanger support member (700), the clothing can be placed in a floating state in the air inside the processing chamber (35).

[0150] According to one embodiment, a clothing treatment device (1) shakes a hanger (900) to remove foreign substances and dust from clothes placed on the hanger (900). When the clothing treatment device (1) shakes clothes, foreign substances and dust from the clothes can be removed, and wrinkles formed on the clothes can also be removed. In order to shake the hanger (900), the hanger support member (700) may be provided in a form that reciprocates in the width direction within the inner case (30) or reciprocates at a set angle around a rotation axis.

[0151] FIG. 3 is a drawing explaining a hanger module (100) according to a first embodiment that moves a hanger (900) back and forth.

[0152] The hanger module (100) is placed on the upper part of the inner case (30). The hanger module (100) may include a driving unit (200), a displacement generating unit (300), and a power transmission unit (400).

[0153] The power transmission unit (400) is configured to shake the clothes hanger support unit (700). The clothes hanger support unit (700) may be provided at the bottom of the power transmission unit (400). When the power transmission unit (400) moves, the clothes hanger support unit (700) moves. When the clothes hanger support unit (700) moves, the clothes hanger (900) mounted on the clothes hanger support unit (700) shakes, which may cause the clothes to flutter.

[0154] The power transmission unit (400) may be provided in multiple units. The clothes hanger support unit (700) coupled to the power transmission unit (400) may also be provided in multiple units.

[0155] The driving unit (200) provides power to move the power transmission unit (400). The driving unit (200) may be provided to be exposed inside the inner case (30) if it can transmit power to the power transmission unit (400). However, since the driving unit (200) is provided to operate by receiving electric energy, it is preferable that exposure to steam or hot air is blocked. In the embodiment, the driving unit (200) is arranged between the upper surface of the inner case (30) and the cabinet (10). Since the driving unit (200) according to the embodiment is located outside the processing chamber (35), it is not exposed to steam or hot air.

[0156] The power transmission unit (400) may be arranged to penetrate the inner case (30). The power transmission unit (400) may penetrate the upper surface of the inner case (30) and extend into the processing chamber (35). The upper end of the power transmission unit (400) is arranged 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). The power transmission unit (400) may receive power from the driving unit (200) and transmit it to the hanger support unit (700).

[0157] In an embodiment, the clothing treatment device (1) may further include a sealing member capable of sealing an area of ​​the inner case (30) penetrated by the power transmission unit (400).

[0158] The sealing member may include a support bearing or the like that is coupled to a hole in the inner case (30) and the support member (800) that allows the power transmission member (400) to pass through and rotatably support the power transmission member (400). The sealing member may block air and steam supplied to the processing chamber (35) from leaking out.

[0159] The upper surface of the inner case (30) can support the load of the power transmission unit (400) and the driving unit (200). Clothing is placed and moved on the power transmission unit (400), and the load of the driving unit (200) is also relatively heavy. Therefore, a support unit (800) may be further provided on the upper surface of the inner case (30). The support unit (800) supports the load of the hanger module (100) so that the hanger module (100) can be stably installed.

[0160] The support member (800) may be placed on the upper portion of the inner case (30). The support member (800) may be supported by being coupled to the cabinet (10). The support member (800) may be made of a durable and non-deformable metal material.

[0161] The power transmission unit (400) and the driving unit (200) can be mounted on the support unit (800). The power transmission unit (400) can extend through the support unit (800) to the processing chamber (35).

[0162] The driving unit (200) includes a motor that rotates the rotation shaft. The driving unit (200) can move the power transmission unit (400) using the power of the rotation shaft.

[0163] It may be difficult to sufficiently swing the power transmission unit (400) with just the rotation shaft rotating in place. In an embodiment, the hanger module (100) may further include a displacement generating unit (300). The displacement generating unit (300) is coupled to the rotation shaft rotated by the motor and generates sufficient displacement to allow the power transmission unit (400) to move. The displacement generating unit (300) may be connected to or coupled to the driving unit (200). The displacement generating unit (300) may be provided to transmit the power of the driving unit (200) to the power transmission unit (400). The displacement generating unit (300) may include an eccentric shaft that rotates along a trajectory larger than the diameter of the rotation shaft. Details will be described with reference to other drawings. The displacement generating unit (300) may be configured in any manner as long as it can generate displacement that causes the power transmission unit (400) to move back and forth within a certain range. The detailed structure will be described later.

[0164] Figure 4 illustrates how a hanger module (100) according to one embodiment of the present invention operates.

[0165] The hanger module (100) may be provided to reciprocate the power transmission unit (400).

[0166] The displacement generating unit (300) can directly move the power transmission unit (400), but can also move the power transmission unit (400) through additional configuration. The hanger module (100) causes the power transmission unit (400) to reciprocate and rotate. The power transmission unit (400) can be provided to reciprocate and swing clockwise or counterclockwise from a fixed position, and clothes placed on the power transmission unit (400) can also reciprocate and swing clockwise or counterclockwise. The power transmission unit (400) is provided to rotate by the hanger module (100), but its position can be changed to the left or right, etc., and it may not move.

[0167] Even if the clothing vibrates due to the power transmission unit (400) inside the inner case (30), the movement of the center of gravity inside the inner case (30) can be limited. Accordingly, even if the hanger module (100) operates, the vibration generated inside the inner case (30) can be drastically reduced, and noise generation can also be minimized.

[0168] The hanger module (100) may further include a reciprocating rotation unit (500) that converts continuous rotational energy generated from the driving unit (200) or displacement generating unit (300) into a reciprocating rotational motion of the power transmission unit (400).

[0169] The reciprocating rotation unit (500) may be provided to connect the displacement generating unit (300) and the power transmitting unit (400) to each other. The reciprocating rotation unit (500) may be provided to connect the displacement generating unit (300) and the power transmitting unit (400) to each other above the inner case (30). The reciprocating rotation unit (500) is prevented from being exposed to the receiving space (21), thereby preventing clothing from being damaged by the reciprocating rotation unit (500).

[0170] The hanger module (100) can rotate a plurality of power transmission units (400) as one unit. The hanger module (100) can be provided to simultaneously rotate a plurality of power transmission units (400) at the same angle. Power generated from the driving unit (200) can be advantageously transmitted to the plurality of power transmission units (400) to rotate all of the power transmission units (400). However, if the driving unit (200) is provided to directly transmit power to each of the power transmission units (400), the structure connecting the driving unit (200) and all of the power transmission units (400) can become complicated. In addition, if a plurality of driving units (200) are provided, or if a plurality of components connecting the driving unit (200) to all of the power transmission units (400) are provided, excessive load may be applied to the inner case (30) or the support unit (800). In addition, the inconvenience of having to control multiple driving units (200) may also arise. In addition, if the displacement generating unit (300) and the reciprocating rotating unit (500) are connected so that the power transmitted from one driving unit (200) is transmitted to each of the power transmission units (400), the arrangement and structure of the displacement generating unit (300) and the reciprocating rotating unit (500) may become complicated, which may lower reliability. Therefore, the hanger module (100) may be equipped so that one driving unit (200) generates power to rotate multiple power transmission units (400).

[0171] The hanger module (100) may be provided so that the power generated in the driving unit (200) is preferentially transmitted to some of the power transmission units (400) or some of the reciprocating rotation units (500), and the remaining power transmission units (400) or the remaining reciprocating rotation units (500) can receive the power secondarily. For example, the reciprocating rotation unit (500) may be provided so as to receive the power transmitted from the driving unit (200) or the displacement generating unit (300) and transmit it to some of the power transmission units (400). That is, the hanger module (100) is provided so as to intensively transmit the power generated in the driving unit (200) to one reciprocating rotation unit (500), so that the power transmission structure can be designed simply and power loss can be minimized.

[0172] According to one embodiment, a hanger module (100) transmits power transmitted from a driving unit (200) to a single reciprocating rotating unit (500). The power transmitted from the driving unit (200) can rotate a specific power transmission unit (400) connected to the reciprocating rotating unit (500). In addition, the hanger module (100) may further include a connecting unit (600) provided to transmit power transmitted to a specific power transmission unit (400) to another power transmission unit (400). For example, the connecting unit (600) may be provided to connect a plurality of power transmission units (400) to each other. Accordingly, when one power transmission unit (400) rotates, the connecting unit (600) can rotate all of the plurality of power transmission units (400).

[0173] Refer to (a) of Fig. 4. When the driving unit (200) operates, the power transmission unit (400) can be rotated to the right by the reciprocating rotation unit (500). At this time, the power transmission units (400) connected to the connecting unit (600) can also all be rotated to the right.

[0174] Refer to (b) of Fig. 4. When the driving unit (200) is further operated, the power transmission unit (400) can be rotated to the left by the reciprocating rotation unit (500). At this time, the power transmission units (400) connected to the connecting unit (600) can also be rotated to the left.

[0175] As this process is repeated, the power transmission unit (400) can rotate left and right.

[0176] At this time, the power transmission unit (400) may be provided to rotate left and right while being fixed in a fixed position. The power transmission unit (400) may be fixed to the support unit (800) so that there is no change in position in the forward, backward, and left and right directions when rotating. The power transmission unit (400) may be fixed so that its position does not move with respect to the up-down direction, the forward-backward direction, and the width direction. However, the power transmission unit (400) may be provided to rotate left and right about the up-down direction or the height direction in which the power transmission unit (400) extends as the rotation axis. As a result, when the driving unit (200) is driven, the clothes hanger support unit (700) can swing back and forth left and right about the power transmission unit (400) as the axis.

[0177] Refer to (c) of Fig. 4. The clothes hanger (900) according to an example may include a ring part (910) and a mounting part (920). The ring part (910) is configured to be mounted on the clothes hanger support part (700). By mounting the ring part (910) on the clothes hanger support part (700), the clothes hanger part (900) can be mounted on the clothes hanger support part (700).

[0178] The fixing portion (920) is a component on which clothing is fixed. The fixing portion (920) and the hook portion (910) are connected to each other. An anti-slip portion (950) may be provided on the surface of the fixing portion (920) to prevent clothing from slipping. The fixing portion (920) may be provided symmetrically around the hook portion (910). The clothes hanger portion (900) may be mounted on the clothes hanger support portion (700) such that the longitudinal direction of the fixing portion (920) is arranged in the front-back direction of the cabinet (10).

[0179] The power transmission unit (400) may be provided to reciprocate at a fixed angle of less than 360 degrees while the center of rotation is fixed. When the power transmission unit (400) rotates to the left, the clothes hanger unit (900) may rotate the left side of the mounting unit (920) to the left and the right side of the mounting unit (920) to the right with respect to the ring unit (910). At this time, the angle (I) at which the left side of the mounting unit (920) rotates is the same as the angle (theta; θ) at which the right side of the mounting unit (920) rotates. The distance at which the left side of the mounting unit (920) moves may be the same as the distance at which the right side of the mounting unit (920) moves.

[0180] The hanger module (100) according to an embodiment of the present invention can rotate the driving unit (200) at a higher RPM to reciprocate the power transmission unit (400) at a faster frequency. The garment treatment device (1) according to an embodiment of the present invention can freely adjust the RPM of the driving unit (200) to adjust the driving frequency or driving cycle of the power transmission unit (400) according to the course.

[0181] Figure 5 illustrates one embodiment of a hanger module (100) according to the first embodiment of the present invention.

[0182] The hanger module (100) may be provided to transmit the power of the driving unit (200) to only one of the plurality of power transmission units (400), and to transmit the power transmitted to a specific power transmission unit (400) to the remaining power transmission units (400) through the connecting unit (600).

[0183] The displacement generating unit (300) or the reciprocating rotating unit (500) may be provided to intensively transmit power generated from one driving unit (200) to one power transmission unit (400). The connecting unit (600) may transmit power transmitted to a specific power transmission unit (400) to all power transmission units (400). The connecting unit (600) may be provided as a rigid body so that its length does not vary. The connecting unit (600) may be provided to connect all power transmission units (400). All power transmission units (400) may rotate in the same direction and at the same angle simultaneously when the connecting unit (600) moves. The hanger module (100) may cause a plurality of power transmission units (400) to move at the same time or at the same angle simultaneously with one driving unit (200).

[0184] The hanger module (100) may include a driving unit (200), a reciprocating rotation unit (500), and a connecting unit (600). The driving unit (200) is fixed to the upper portion of the inner case (30) and provides power to move the power transmission unit (400). A plurality of reciprocating rotation units (500) are provided. The plurality (500) of reciprocating rotation units (500) are respectively coupled to the plurality of power transmission units (400). The reciprocating rotation units (500) receive power from the driving unit (200) and rotate so that the rotation direction is repeatedly changed. The connecting unit (600) connects the plurality of reciprocating rotation units (500) to each other.

[0185] The connecting portion (600) may include a link bar. The link bar is provided to connect a plurality of reciprocating rotating portions (500) to integrally rotate the plurality of reciprocating rotating portions (500). The connecting portion (600) may be provided in a single unit. The connecting portion (600) may also be provided to connect all of the power transmission portions (400). The connecting portion (600) may be coupled to either the front or the rear of the reciprocating rotating portion (500). At least one of the displacement generating portion (300) and the driving portion (200) may be coupled to the other of the front or the rear of the reciprocating rotating portion (500). At least one of the displacement generating portion (300) and the driving portion (200) may be arranged at the other of the front or the rear of the reciprocating rotating portion (500). The connecting portion (600) and the driving portion (200) may not interfere with each other.

[0186] The connecting part (600) may be provided to reciprocate in the width direction of the inner case (30) and rotate a plurality of reciprocating rotating parts (500).

[0187] The driving unit (200) may include a motor (210), a transmission unit (230), and a power shaft (240). The motor (210) rotates the rotation shaft (220). The power shaft (240) is provided to rotate together with the rotation shaft (220). The transmission unit (230) connects the power shaft (240) and the rotation shaft (220) to transmit the rotational force of the rotation shaft (220) to the power shaft (240).

[0188] The motor (210) is fixed to the upper part of the inner case (30) and rotates the rotation shaft (220). The rotation shaft (220) is provided to rotate at a speed that is too fast compared to the appropriate cycle for reciprocating the power transmission unit (400). Considering this, if the RPM of the rotation shaft (220) is lowered, there is a concern that the output of the motor (210) may not be transmitted to the power transmission unit (400). The transmission unit (230) transmits the output of the rotation shaft (220) as is to the power transmission unit (400), but can transmit it by lowering the RPM of the rotation shaft (220).

[0189] The transmission unit (230) is connected to the rotation shaft (220) and rotates. The transmission unit (230) has a diameter larger than that of the rotation shaft (220) and can rotate. The transmission unit (230) can transmit the torque of the rotation shaft (220) while rotating slower than the RPM of the rotation shaft (220).

[0190] The power shaft (240) may be provided to rotate by the transmission unit (230). The power shaft (240) is provided separately from the rotation shaft (220). The power shaft (240) is configured to directly transmit power to the power transmission unit (400).

[0191] The reciprocating rotating part (500) may be coupled to the power transmission part (400) and may be provided 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 configured to be coupled to the upper portion of the power transmission part (400) and rotate the power transmission part (400). The rotation center of the reciprocating lever (510) may be coupled to the support shaft (410, see FIG. 6) of the power transmission part (400). The reciprocating lever (510) may be provided in a rib or rod shape.

[0192] The reciprocating levers (510) may be respectively coupled to the upper ends of the plurality of power transmission units (400). Some of the reciprocating levers (510) may be provided to be connected to the transmission unit (230) and to receive power from the motor (210). The reciprocating levers (510) may be provided to rotate at a predetermined angle when the transmission unit (230) is rotated by the motor (210). The power transmission unit (400) may be provided to be coupled to the rotation center of the reciprocating levers (510) and to rotate together with the reciprocating levers (510). The plurality of reciprocating levers (510) may be arranged to be connected by a connecting portion (600). The connecting portion (600) may be provided to connect one end of the plurality of reciprocating levers (510). When any one of the plurality of reciprocating levers (510) rotates, the connecting portion (600) moves so that the plurality of reciprocating levers (510) can rotate simultaneously and at the same time.

[0193] The motor (210) may be supported on the support (800). The transmission unit (230) may be supported on the support (800). The power transmission unit (400) may be supported on the support (800). The reciprocating lever (510) may be supported on the support (800).

[0209] The displacement generating unit (300) may include an eccentric shaft (310) that is inserted into the main receiving hole (5112) at the end of the power shaft (240) and can rotate. In the embodiment, the main receiving hole (5112) is provided in the form of a hole, but since it is sufficient for the power shaft (240) to be inserted and rotated, the main receiving hole (5111) may also be formed in the form of a groove. The eccentric shaft (310) may be provided to rotate along a trajectory with a larger diameter than the central axis of the power shaft (240).

[0210] The main body (511) may be fixedly coupled to a support shaft (410) that penetrates the inner case (30) or the support member (800). The main body (511) may be provided with a rotation center coupled to the support shaft (410) and one end configured to receive an eccentric shaft (310).

The support bearing (530) and the main lever (511) are provided to support the load of the support shaft (410). The support bearing (530) and the auxiliary lever (512) are also provided to support the load of the support shaft (410) coupled thereto. The load of the support bearing (530) and the reciprocating lever (510) is supported on the support member (800) through the support bearing (530). Consequently, the support member (800) supports the load of the entire hanger module (100) and can be fixed to the cabinet (10).

[0212] Figure 8 illustrates an exploded perspective view of a hanger module (100) according to the first embodiment.

[0213] 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 a reciprocating lever (510). The auxiliary support unit (420) is coupled to the support shaft (410) and is placed in the processing chamber (35). A clothes hanger unit (900) or a clothes hanger support unit (700) provided to hold clothes is coupled to the auxiliary support unit (420).

[0214] The support shaft (410) may be provided in a cylindrical shape with a length longer than its diameter. The support shaft (410) may be easily rotated by a reciprocating lever (510). The support shaft (410) may be provided with a diameter much smaller than that of the auxiliary support member (420) so that it may penetrate the inner case or support member (800) with a smaller area. Accordingly, the possibility of hot air or steam supplied to the receiving space through the upper portion of the inner case (30) leaking may be further reduced.

[0215] The auxiliary support member (420) may be provided with a larger cross-sectional area than the support shaft (410) and may be provided with a longer length than the support shaft (410). The auxiliary support member (420) may secure rigidity and an area that can support and rotate the clothes hanger support member (700) and the clothes hanger member (900).

[0216] The support member (800) may include a support plate (810) through which the support shaft (410) passes and on which the driving member (200) can be supported. The support plate (810) may be provided with a metal plate to ensure rigidity and durability, and may extend in a direction in which a plurality of power transmission members (400) are arranged. The support member (800) may include a union body (812) extending upward from both ends of the support plate (810) to form a space in which the driving member (200) and the reciprocating rotation member (500) are seated between the inner case (30) and the upper part of the cabinet (10), and a seat body (813) extending from the extension body (821) to be seated on the support frame (12).

[0217] The support member (800) may include an axial penetration member (820) through which the support shaft (410) can pass.

[0218] The shaft penetration portion (820) may be provided in multiple numbers so that it can be provided at a position corresponding to the position where the power transmission portion (400) is arranged, and may be arranged spaced apart from each other along the length direction of the support plate (810).

[0219] The support member (800) may further include an auxiliary plate (880) coupled to the lower portion of the support plate (810). The auxiliary plate (880) may be made of a resin series and may be provided so as to accommodate a portion of the outer surface of the power transmission member (400).

[0220] The auxiliary plate (880) may include a plurality of receiving holes (882) arranged at the lower portion of the support plate (810) and capable of rotatably receiving the power transmission unit (400), a plurality of extension steps (883) extending with a wider width from the receiving holes (882), and a fixing plate (881) extending from the extension steps (883) to face the support plate (810) and capable of being coupled and fixed to the support plate (810).

[0221] The receiving hole (882) may be provided at the upper end of the support shaft (410) or the auxiliary support member (420) to prevent hot air or air from being discharged into the shaft penetration member (820). The extension step (883) may serve to distribute the load or impact transmitted to the auxiliary plate (880) and may serve to prevent collision or interference between the receiving hole (882) and the clothes hanger member (900).

[0222] The support member (800) may further include a mounting plate (860) that is mounted on top of the support plate (810).

[0223] The mounting plate (860) can play a role in supporting a bearing mounted on the shaft penetration portion (820) and at the same time prevent the reciprocating lever (510) and the connecting portion (600) from colliding with or rubbing against the supporting plate (810).

[0224] The mounting plate (860) may include a mounting plate (861). The mounting plate (861) is mounted on the upper portion of the support plate (810). A mounting hole (862) may be formed in the mounting plate (861) and positioned in an area corresponding to the shaft penetration portion (820) through the mounting plate (861).

[0225] The reciprocating lever (510) may include a main lever (511) that directly receives power from the driving unit (200) and an auxiliary lever (512) that receives power from the main lever (511) through a connecting portion (600). The main lever (511) and the auxiliary lever (512) may be coupled to their respective support shafts (410) and may be provided to rotate around the support shaft (410) as the center of rotation.

[0226] The link bar (610) may include a link body (611) and a connecting hook (612). The link body (611) may be mounted on the main lever (511) and the auxiliary lever (512) to be connected to each other. The connecting hook (612) may protrude from the link body (611) and be rotatably provided on the main lever (511) and the auxiliary lever (512). When the link bar (610) rotates left and right, the main lever (511) or the auxiliary lever (512) may reciprocally rotate left and right.

[0227] The reciprocating lever (510) may further include a link bearing (513). A plurality of link bearings (513) may be provided. The link bearing (513) is coupled to one end of the main lever (511) to rotatably support the connecting hook (612). The link bearing (513) is coupled to one end of the auxiliary lever (512) to rotatably support the connecting hook (612).

[0228] The reciprocating rotating part (500) may further include a support bearing (530) that can rotatably support the support shaft (410) or the reciprocating lever (510). The support bearing (530) rotatably accommodates the support shaft (410) and may be mounted on the shaft-through part (820). The reciprocating lever (510) may be arranged on top of the support bearing (530). The support bearing (530) may be provided in a stacked manner in multiple pieces, and may be provided as a ball bearing, an oilless bearing, or a bushing.

[0229] The mounting plate (860) is provided to support the support bearing (530) and may be provided to block hot air or moisture from being exposed to the outer surface of the support bearing (530). An auxiliary plate (880) may also be provided to be disposed below the support bearing (530) and to block hot air or moisture from being exposed to the outer surface of the support bearing (530).

[0230] Figure 9 illustrates the operation method of the hanger module (100) according to the first embodiment.

[0231] The main lever (511) may include a main body (5111). The main body (5111) is coupled to a support shaft (410) and coupled to a link bar (610). The main body (5111) may include a main center hole (5115) coupled to the support shaft (410) and capable of rotating the support shaft (410). The main body (5111) may be provided to extend from the main center hole (5115) to both sides. The main body (5111) may be provided with a main receiving hole (5112) at one end for receiving power from a driving unit (200), and may include a main transmission hole (5113) at the other end for receiving and coupling a link bar (610).

[0232] The auxiliary lever (512) may include an auxiliary body (5121) and an auxiliary center hole (5125). The auxiliary center hole (51125) is coupled to the support shaft (410). The auxiliary body (5121) is formed to extend to one side from the auxiliary center hole (5125). The auxiliary body (5121) has an auxiliary transmission hole (5123) coupled to a link bar (610). The auxiliary body (5121) may be provided to have a shorter length than the main body (5111).

[0233] The distance from the main center hole (5115) to the main transmission hole (5113) can be set to be the same as the distance from the auxiliary center hole (5125) to the auxiliary transmission hole (5123). The link bar (610) can be installed on the upper portion of the auxiliary transmission hole (5123) and the main transmission hole (5113) to connect the auxiliary lever (512) and the main lever (511) to each other.

[0234] Referring to Fig. 9 (b), the driving unit (200) may be provided such that the power shaft (240) is inserted into the main receiving hole (5112). Accordingly, the driving unit may be provided such that the power shaft (240) is directly rotated to rotate the main receiving hole (5112) left and right.

[0235] An eccentric shaft (310) is accommodated in the main receiving hole (5112). The diameter of the eccentric shaft (310) may be set smaller than the diameter or width of the main receiving hole (5112). As a result, the eccentric shaft (310) may be inserted into and supported in the main receiving hole (5112). A certain radius of rotation of the eccentric shaft (310) may be set larger than the width or 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 move left and right with respect to the main center hole (5115).

[0236] When the eccentric shaft (310) rotates in a specific direction, the main receiving hole (5112) of the main body (511) also reciprocates along a specific direction, and as a result, the central hole (5115) of the main body (511) also rotates in the same direction as the main receiving hole (5112), and the main transmission hole (5113) can reciprocate in a specific direction and an opposite direction.

[0237] When the eccentric shaft (310) rotates, the support shaft (410) reciprocates together with the main center hole (5115), so that the power transmission unit (400) can reciprocate, and the main transmission hole (5113) also reciprocates to move the link bar (610) reciprocally, so that the auxiliary lever (512) can also reciprocate around the auxiliary center hole (5125) and the support shaft (410). The power transmission unit (400) coupled to the auxiliary lever (512) can also reciprocate.

[0238] The power transmission unit (400) may be provided with a screw thread along the circumference of the upper portion of the support shaft (410). The main transmission hole (5113) and the auxiliary center hole (5125) may be directly connected and fixed to the support shaft (410) using a screw thread or the like.

[0239] The power transmission unit (400) may further include a transmission coupling unit (415) that is coupled to the screw thread of the support shaft (410) so that the support shaft (410) passes through the main transmission hole (5113) and the auxiliary center hole (5125) and then fixes the support shaft (410) to the main transmission hole (5113) and the auxiliary center hole (5125). Due to the transmission coupling unit (415), the support shaft (410) and the reciprocating lever (510) are coupled, so that the support shaft (410) and the reciprocating lever (510) can rotate simultaneously.

[0240] Figure 10 is an additional drawing for explaining the process of reciprocating rotation of the reciprocating rotating part (500).

[0241] As shown in (b) of Fig. 10, the eccentric shaft (310) is positioned at the I position and can be positioned at one end or the end of the main receiving hole (5112). Thereafter, when the power shaft (240) is rotated 90 degrees clockwise, the eccentric shaft (310) is spaced apart from the rotation center of the power shaft (240) by 1 / 2R, so the eccentric shaft (310) can move to the right by 1 / 2R. The main center hole (5112) also moves to the right, and the main body (5111) rotates the support shaft (410) clockwise. Accordingly, the power transmission unit (400) coupled to the main lever (511) rotates clockwise, and the clothes hanger support unit (700) coupled to the power transmission unit (400) and the clothes hanger unit (900) mounted on the clothes hanger support unit (700) also rotate clockwise. Therefore, the clothes also rotate clockwise.

[0242] Meanwhile, the main transmission hole (5113) moves to the left in the opposite direction to the main receiving hole (5112) with the support shaft (410) as the center. Accordingly, the connecting part (600) is moved to the left, and all auxiliary levers (512) connected to the connecting part (600) are moved to the left, thereby rotating all power transmission parts (400) connected to the auxiliary levers (512) in a clockwise direction.

[0243] Afterwards, when the eccentric shaft (310) rotates 90 degrees, it is placed at position III, and when it rotates 180 degrees, it is placed at position IV. In this 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) can change from state (b) to state (a). In this process, the power transmission unit (400) coupled to the main lever (511) rotates clockwise, and the clothes hanger support unit (700) coupled to the power transmission unit (400) and the clothes hanger unit (900) mounted on the clothes hanger support unit (700) also rotate counterclockwise. Accordingly, the clothes also rotate counterclockwise.

[0244] Meanwhile, the main transmission hole (5113) moves to the right in the opposite direction to the main receiving hole (5112) with the support shaft (410) as the center. Accordingly, the connecting part (600) moves to the right, and all auxiliary levers (512) connected to the connecting part (600) move to the left, thereby rotating all power transmission parts (400) connected to the auxiliary levers (512) counterclockwise.

[0245] If the power shaft (240) continuously rotates clockwise, the eccentric shaft (310) also continuously rotates, and the aforementioned process can be repeated infinitely. If the power shaft (240) continuously rotates counterclockwise, the eccentric shaft (310) also continuously rotates counterclockwise, and the aforementioned process can be repeated infinitely in reverse order. As a result, the clothing can be swayed left and right around the support shaft (410) of the mounted power transmission unit (400).

[0246] Fig. 11 is a drawing schematically showing the movement of a hanger (900) by a hanger module (100) according to the first embodiment.

[0247] The hanger module (100) according to the first embodiment allows the hanger (900) to reciprocate within a range of a set angle (theta) with the center (O) as the center (901). According to the first embodiment, the hanger (900) reciprocates 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 secured to the hanger support member (700), the position of the hanger support member (700, see FIG. 4) that positions the hanger (900) at the first position (P1) is referred to as the first position, and the position of the hanger support member (700, see FIG. 4) that positions the hanger (900) at the second position (P2) is referred to as the second position. According to the first embodiment, the clothing placed on the hanger (900) experiences different displacements at the center (901) and the end (902). According to the embodiment, the minimum displacement occurs at the center (901), and the displacement at the center (901) may be Xmin. Xmin may be 0. The maximum displacement occurs at the end (902), and the displacement at the end may be 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 rotational center (901) of the hanger. That is, the displacement occurs differently 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 from the end (901) is greater than the force transmitted from the center (902). Therefore, in the first embodiment, the force transmitted to the clothing is defined as the reference displacement (Xref) at the reference portion (903), which is the midpoint between the end portion (902), where the maximum displacement occurs, and the center portion (901), where the minimum displacement occurs.

[0248] According to the first embodiment, the force generated in the clothing can be mathematically defined as follows.

[0249] Force generated on clothing =

[0250] m: weight of clothing, Xref: reference displacement, t=time taken to move from P1 to P2

[0251] Figure 12 illustrates a hanger module (100') according to a second embodiment of the present invention.

[0252] The hanger module (100') may include a support bar (120'), a hanger support member (700'), and a driving member (400').

[0253]

[0254] The driving unit (400') may include a motor (451') that is fixed to the upper portion of the support bar (120') and rotates the rotation shaft (453'). It may include an eccentric shaft (455') that is coupled to the rotation shaft (453') and rotates along a trajectory larger than the rotational diameter of the rotation shaft (453').

[0255] A reciprocating guide unit (500') that receives power by accommodating an eccentric shaft (455') may be installed at the center of the support bar (120'). The eccentric shaft (455') may be provided to move along the rotation of the rotary shaft (453') while being coupled to the reciprocating guide unit (500') and to reciprocate the reciprocating guide unit (500') left and right. The eccentric shaft (455') may be provided to rotate by being coupled to the end of a connecting shaft (452') coupled to the end of the rotary shaft (453').

[0256] Fig. 13 illustrates a structure in which a support bar (120') of a hanger module (100') according to the second embodiment moves left and right.

[0257] The reciprocating guide unit (500') may be formed in the thickness direction of the support bar (120') and may be provided with a slit (541') that accommodates an eccentric shaft (455').

[0258] Refer to (a) of Fig. 13. The eccentric shaft (455') may be inserted into the slit (541') and may be provided to rotate along an arc path with a radius R that is a distance away from the rotational axis (453'). The support bar (120') may be provided to be fixed so as to be movable only left and right in the garment treatment device (1) and not to be moved forward or backward.

[0259] Referring to Fig. 13 (b), when the eccentric shaft (455') rotates 90 degrees to the right, the slit (541') can move R to the right together with the eccentric shaft (455') due to the eccentric shaft (455') moving R to the right. As a result, the support bar (120') moves to the right.

[0260] In this way, when the eccentric shaft (455') rotates 180 degrees to the left, the slit (541') will move to the left, and the support bar (120') will also move to the left. When the rotation shaft (453') rotates once, the support bar (120') can move back and forth left and right once, and when the rotation shaft (453') rotates continuously, the support bar (120') can move back and forth left and right several times. A hanger (900) can be placed on the hanger support member (700'). Clothing placed on the hanger support member (700') can be moved left and right, so that foreign substances or dust can be separated.

[0261] Fig. 14 is a drawing schematically showing the movement of a hanger (900) by a hanger module (100') according to the second embodiment.

[0262] 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. The second position (P2) is the maximum displacement in the left direction.

[0263] According to the second embodiment, when moving from the first position (P1) to the second position (P2), the displacement at all positions of the hanger (900) is equal to X.

[0264] According to the second embodiment, the force generated in the clothing can be mathematically defined as follows.

[0265] Force generated on clothing =

[0266] m: weight of clothing, X: displacement, t=time taken to move from P1 to P2

[0267] Considering the space constraints of the clothing treatment device (1) and issues such as friction between clothes, the maximum displacement of the hanger is limited. Therefore, the maximum displacement Xmax of the first embodiment and the maximum displacement X of the second embodiment may be substantially the same. In the embodiment, Xmax and X may be 28 mm to 84 mm. Preferably, they may be 50 mm to 60 mm.

[0268] Considering that the force transmitted to the clothing in the device according to the first embodiment is Xref rather than 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.

[0269] <Method for driving a hanger module according to an embodiment of the present invention>

[0270] According to an embodiment of the present invention, clothes are processed by moving the hanger (900) back and forth from the first position (P1) to the second position (P2). The reciprocating speed can be defined by the frequency. The frequency can be defined in units of rpm. The rpm can be the number of back and forth movements per minute. According to an embodiment, when the rotation shaft (220) of the motor (210) rotates once, the hanger (900) can move from the first position (P1) to the second position (P2) and then return to the first position (P1), so the rpm of the motor (210) can be the same as the rpm of the hanger (900).

[0271] The control unit (P) can control the rpm of the hanger (900). In an embodiment, the control unit (P) can control the rpm of the hanger (900) by controlling the rotation speed of the motor. The hanger (900) can move at a reference frequency. In an embodiment, the reference frequency can be defined as a standard according to the description below.

[0272] <Reference frequency>

[0273] Figure 15 is a drawing to explain the range of frequencies defined as the reference frequency, and shows the lateral behavior of the sample (M) recorded.

[0274] Refer to Fig. 15. The sample (M) is placed on a hanger (900) inside the clothing treatment device (1). The behavior of the sample (M) forms a waveform. The sample (M) is made of cotton, has a size of 20x90cm (width x height), and weighs 151g / m2. At the reference frequency, the first waveform (W1) when the sample is tilted to one side and the second waveform (W2) when the sample is tilted to the other side in the waveform according to the behavior of the sample (M) have two overlapping points. When two overlapping points occur, the amplitude of the clothing is sufficiently secured, and the treatment efficiency is high. When there are three overlapping points, the amplitude of the clothing is not as large as when there are two overlapping points, but when the clothing is wet, excessive impact may be applied, which may cause deformation of the clothing. In an embodiment of the present invention, the frequency within the range where the number of overlapping points of two outermost waveforms formed according to the behavior of the sample (M) becomes two is defined as the reference frequency. According to the second embodiment, the reference frequency is 200 rpm to 250 rpm.

[0275] Figure 16 illustrates the behavior of the sample (M) according to the frequency.

[0276] Refer to Figure 16. From left to right, the sample (M) is moved at higher frequencies. The range where the number of overlapping points is 2 is defined as the reference frequency. At frequencies lower than the reference frequency, there is 1 overlapping point. At frequencies lower than the reference frequency, there may be no overlapping points. At frequencies higher than the reference frequency, there are 3 overlapping points, and more may occur.

[0277] Figure 17 shows the behavior according to the results of exciting a hemp sample, a cotton sample, and a silk sample at a reference frequency.

[0278] The size of each sample is the same, 20x90cm (width x height). In the experimental example, when a cotton sample is excited with a reference frequency, two overlapping points occur. When a hemp sample is excited with the same reference frequency, two overlapping points occur. When a silk sample is excited with the same reference frequency, three overlapping points occur.

[0279] Figure 18 shows the behavior of a cotton sample, a cotton sample, and a silk sample when excited at a low frequency that is lower than the reference frequency.

[0280] In the experimental example, the low-speed frequency is the frequency at which one overlapping point occurs when a cotton sample is excited. When a hemp sample is excited at the same low-speed frequency, zero overlapping points may occur. When a silk sample is excited at the same low-speed frequency, two overlapping points may occur.

[0281] As can be seen from the experimental examples in Figures 17 and 18, the better the drape (flexibility) of the fabric, the more overlapping points it has at the same rpm. As the number of overlapping points increases, the size of the fold (thick part of the wave) formed decreases, and thus the degree of force concentration also changes.

[0282] Improving Clothing Processing Efficiency through Variable Frequency Control

[0283] According to an embodiment of the present invention, the vibration frequency applied to clothing can be variably controlled, and the efficiency of clothing processing can be improved by variable control of the vibration frequency. The vibration frequency applied to clothing by the hanger module (100, 100') can be varied within the frequency range referenced through FIG. 19.

[0284] The first frequency, which is the smallest frequency, may be a frequency within a range where at least one overlapping point of the silk sample occurs. The first frequency may be 40% or more of the reference frequency.

[0285] The reference frequency is named the fourth frequency.

[0286] The sixth frequency, which is the highest frequency, may be the frequency corresponding to the maximum output of the motor. The maximum output of the motor may be set by considering the vibration of the motor itself and the noise caused by the vibration of the clothing treatment device (1).

[0287] According to the hanger module (100) according to the first embodiment, the first vibration frequency may be 120 rpm, the second vibration frequency may be 150 rpm, the third vibration frequency may be 200 rpm, the fourth vibration frequency may be 250 rpm, the fifth vibration frequency may be 300 rpm, and the sixth vibration frequency may be 350 rpm.

[0288] According to the moving hanger (100') according to the second embodiment, the first vibration frequency may be 80 rpm, the second vibration frequency may be 110 rpm, the third vibration frequency may be 150 rpm, the fourth vibration frequency may be 180 rpm, the fifth vibration frequency may be 210 rpm, and the sixth vibration frequency may be 250 rpm.

[0289] In the case of the first embodiment, the first frequency is 120 rpm and the sixth frequency is 350 rpm, so the difference is 230 rpm, and the range of the frequency is wide, so that more precise clothing processing is possible than in the second embodiment simply by varying the frequency, and high clothing processing performance can be expected.

[0290] Referring to FIG. 20, six motion modes provided by a garment treatment device (1) according to one embodiment of the present invention are described.

[0291] Motion mode is a control method by which the hanger module (100) moves clothes. Each motion mode moves clothes using different vibration frequencies.

[0292] Motion Mode 1 is a mode that excites clothing at a reference frequency, the fourth frequency. While operating in Motion Mode 1, the frequency remains constant at the fourth frequency. Motion Mode 1 is the standard mode for handling all clothing except those requiring delicate care.

[0293] Second Motion Mode vibrates clothing at a sixth frequency. While operating in Second Motion Mode, the frequency remains constant at this frequency. Second Motion Mode utilizes the motor's maximum output to shake clothing at its maximum frequency, effectively removing dust from the clothing.

[0294] The third motion mode is a mode in which the frequency is varied within a frequency range below the reference frequency. In an embodiment, the frequency may be varied between a first frequency and a third frequency during one variable period. Referring further to FIG. 21, the third motion mode will be described. In the third motion mode, the frequency is varied between a first frequency equal to or greater than the minimum vibration frequency, a second frequency greater than the first frequency, and a third frequency greater than the second frequency and equal to or less than the fourth frequency. The third motion mode may include a first section in which the frequency is varied from the first frequency to the third frequency during a first time (t0 to t2) during one variable period (t0 to t6: T1), and a second section in which the frequency is varied from the third frequency to the first frequency during a second time (t2 to t3) that is shorter than the first time. According to the third motion mode, when drying various clothes in combination, the wind can evenly pass between the clothes. In other words, the third motion mode can increase the drying efficiency of the clothes when applied to a section that reduces the moisture content of the clothes. In an embodiment, the hanger module (100) can be driven in the third motion mode during the drying cycle. The variable cycle of the frequency can be set to 20 seconds to 1 minute. If the variable cycle is less than 20 seconds, the intended vibration may not be transmitted to the clothes. If the variable cycle is greater than 1 minute, the frequency variation may not sufficiently occur within the limited cycle time. However, the variable cycle of the frequency can be changed according to the design specifications.

[0295] The fourth motion mode is a mode in which the frequency is varied within a frequency range greater than or equal to the reference frequency. In an embodiment, the frequency may vary between the fourth frequency and the sixth frequency during one variable period. Referring further to FIG. 22, the fourth motion mode will be described. In the fourth motion mode, the frequency varies between a frequency greater than or equal to the reference frequency (the fourth frequency in an embodiment), a fifth frequency greater than the fourth frequency, and a frequency greater than the fifth frequency and equal to or less than the sixth frequency (the sixth frequency in an embodiment). The fourth motion mode may include a first section in which the frequency varies from the fourth frequency to the sixth frequency during a first time (t0 to t2) of one variable period (t0 to t6: T1), and a second section in which the frequency varies from the sixth frequency to the fourth frequency during a second time (t2 to t3) that is shorter than the first time. The fourth motion mode improves wrinkle removal performance by changing the position of the overlapping point according to the clothing's wave motion. The fourth motion mode can be applied to wrinkle removal sections. The fourth motion mode can be applied to sections with increasing moisture content. When the fourth motion mode is applied, uniform wrinkle removal performance can be achieved.

[0296] The fifth motion mode excites garments at the first frequency. While operating in this mode, the frequency remains constant. This mode is used for handling knitwear that is prone to stretching and blouses that are susceptible to damage. This mode prevents stretching in knitwear and prevents hanger marks from forming on garments.

[0297] The sixth motion mode is a mode that excites clothing at a second frequency. While operating in the sixth motion mode, the frequency remains constant from the second frequency. The sixth motion mode provides the force to move the disheveled clothing back into place. At the end of the cycle, the hanger module (100) can operate in the sixth motion mode.

[0298] Figure 23 is a diagram explaining the driving state of each configuration for each administration according to one embodiment of the present invention.

[0299] The garment treatment device (1) according to the embodiment can provide five cycles. The garment treatment device (1) can include a pre-steam cycle (PreSteam), a pre-heat cycle (PreHeat), a steam cycle (Steam), a stay cycle (Stay), and a drying cycle (Drying).

[0300] The pre-steam cycle is a cycle that heats water to generate steam. During the pre-steam cycle, the circulation fan operates (On) while generating steam, allowing air to circulate within the processing chamber (35). At this time, the heat pump is turned off.

[0301] The preheat cycle is a cycle that preheats the interior of the processing chamber (35). In the preheat cycle, the heat pump is turned on to heat the air inside the processing chamber (35). Steam can be supplied to the processing chamber (35) during the preheat cycle. The circulation fan can be turned on during the preheat cycle to circulate the air inside the processing chamber (35). The moisture content of clothing can increase during the preheat cycle.

[0302] The steam cycle is a cycle that supplies steam to clothing to increase its moisture content. During the steam cycle, steam can be supplied to the treatment chamber (35). During the steam cycle, a circulation fan can be turned on to circulate the air inside the treatment chamber (35). The moisture content of the clothing can increase during the steam cycle. During this time, the heat pump is turned off.

[0303] The Stay cycle is a cycle that maintains the moisture content of clothing. During the Stay cycle, steam is no longer supplied. During the Stay cycle, the circulation fan operates (On) to circulate the air inside the processing chamber (35). At this time, the heat pump is kept in the Off state. The Stay cycle is a cycle that does not supply steam any longer and does not operate the moisture removal module to remove moisture. The moisture content of clothing can be maintained during the Stay cycle. The moisture content of clothing may increase or decrease during the Stay cycle.

[0304] The drying cycle is the cycle for drying clothes. During the drying cycle, a heat pump is operated. The heat pump removes moisture from the air in the treatment chamber (35). During the drying cycle, a circulation fan is operated (On) to circulate the air inside the treatment chamber (35). The moist air in the treatment chamber (35) is circulated through the circulation duct by the circulation fan, and moisture is removed by the heat pump. During the drying cycle, the moisture content of the clothes is reduced.

[0305] The garment treatment device (1) provides various treatment courses. The treatment courses are configured by combining one or more of the following: pre-steam cycle (PreSteam), pre-heat cycle (PreHeat), steam cycle (Steam), stay cycle (Stay), and drying cycle (Drying).

[0306] While the pre-steam cycle (PreSteam), pre-heat cycle (PreHeat), steam cycle (Steam), stay cycle (Stay), and drying cycle (Drying) are in progress, the hanger module (100, 100') can be driven in the first motion mode to the sixth motion mode.

[0307] Figure 24 is a diagram showing an example of a processing course provided by a clothing processing device (1) and the motion mode of the hanger module for each cycle.

[0308] A standard styling course can sequentially perform a pre-steam cycle (PreSteam), a pre-heat cycle (PreHeat), a steam cycle (Steam), a stay cycle (Stay), and a drying cycle (Drying). While the pre-steam cycle is in progress, the hanger module (100, 100') is driven in the second motion mode. While the pre-heat cycle is in progress, the hanger module (100, 100') is driven in the fourth motion mode. While the steam cycle is in progress, the hanger module (100, 100') is driven in the fourth motion mode. While the stay cycle is in progress, the hanger module (100, 100') is driven in the second motion mode. While the drying cycle is in progress, the hanger module (100, 100') is driven in the first motion mode. According to the standard styling course of the embodiment, wrinkles can be effectively removed because the clothing is moved to the fourth motion mode while the moisture content of the clothing increases.

[0309] The wool / knit styling course can sequentially perform a pre-steam cycle (PreSteam), a pre-heat cycle (PreHeat), a steam cycle (Steam), a stay cycle (Stay), and a drying cycle (Drying). The hanger module (100, 100') is not driven while the pre-steam cycle (PreSteam), the pre-heat cycle (PreHeat), the steam cycle (Steam), and the stay cycle (Stay) are in progress. The hanger module (100, 100') is driven in the fifth motion mode while the drying cycle is in progress. According to the wool / knit styling course of the embodiment, since the fifth motion mode is operated while the moisture content of the clothing is reduced, damage such as stretching of the clothing can be prevented.

[0310] The silk styling course can sequentially perform a pre-steam cycle, a steam cycle, a stay cycle, and a drying cycle. While the pre-steam cycle, the steam cycle, the stay cycle, and the drying cycle are being operated, the hanger module (100, 100') is operated in the sixth motion mode. According to the silk styling course of the embodiment, it is possible to increase silk treatment efficiency while minimizing damage to the silk.

[0311] In an embodiment not shown in the diagram, the stay operation can be performed at a frequency lower than the reference frequency. For example, the stay operation can be performed in the third motion mode, the fifth motion mode, or the sixth motion mode, which operate at a frequency lower than the reference frequency.

[0312] In an embodiment not shown in the diagram, the hanger module (100, 100') may be driven in the third motion mode while the stay cycle and / or drying cycle are in progress after the steam cycle. According to the third motion mode, when processing various types of clothing, the wind can be evenly circulated between the clothing. That is, when the third motion mode is applied while the circulation fan is running to circulate the air, the efficiency of processing the clothing can be increased. When operating in the third motion mode in the stay cycle, the moisture content of the clothing can be evenly distributed. When operating in the third motion mode in the drying cycle, the efficiency of drying the clothing can be increased.

[0313] Figure 25 is a diagram showing an example of a treatment course of a clothing treatment device (1) and the motion mode of the hanger module for each drying cycle.

[0314] The standard drying course operates the hanger module (100, 100') in the first motion mode when the drying process is in progress.

[0315] The delicate low-temperature drying course operates the hanger module (100, 100') in the fifth motion mode during the drying cycle. The delicate low-temperature drying course vibrates the clothing at the lowest speed to minimize damage to the clothing.

[0316] The time-drying course operates the hanger module (100, 100') in the sixth motion mode during the drying cycle. The time-drying course vibrates clothing at a frequency lower than the standard frequency to reduce damage to clothing, but at a frequency higher than that of the delicate low-temperature drying course to increase processing speed. The sixth motion mode allows clothes to be returned to their original position and organized.

[0317] The thick padding drying course operates the hanger module (100, 100') in the fifth motion mode during the drying cycle. In the thick padding drying course, the garment is vibrated at the lowest speed to ensure that the padding's filling remains rich.

[0318] The composite clothing drying course operates the hanger module (100, 100') in the third motion mode during the drying process. According to the composite clothing drying course, air can be evenly circulated between the garments, thereby improving the uniformity of drying when drying composite clothing.

[0319] The amplitude corresponding to the displacement according to the reciprocating motion of the clothes hanger support (700, 700') in the first to sixth motion modes is the same. In the first embodiment, Xmin, Xmax, and Xref referenced in FIG. 11 are all the same in the first to sixth frequencies, and are all the same in the first to sixth motion modes. In the second embodiment, X referenced in FIG. 14 is all the same in the first to sixth frequencies, and are all the same in the first to sixth motion modes. Since the amplitude is the same, the vibration noise of the clothes treatment device (1) is relatively constant, and since the frequency can be varied, the clothes treatment efficiency such as wrinkle removal performance, hair removal performance, and drying performance can be improved.

In other words, it should be understood that this application covers any adaptation or variation of the disclosure.
