Description

Technical Field

[0001] This disclosure relates to a garment processing apparatus, and more particularly, to a garment processing apparatus having garment supports for holding garments and a garment processing process thereof. Background Technology

[0002] Clothing handling equipment refers to equipment designed to wash and dry clothes and remove wrinkles from clothes at home or in a laundry room. Clothing handling equipment may include washing machines for washing clothes, dryers for drying clothes, washer / dryer machines with washing and drying functions, clothing management equipment for refreshing clothes, and steamers for removing wrinkles from clothes.

[0003] A steam iron is a device used to supply steam to clothing to remove wrinkles. Unlike a regular iron that applies heat directly to clothing (e.g., by bringing a hard object into contact with the clothing), a steam iron removes wrinkles by applying heat through convection.

[0004] Clothing management equipment is used to keep clothing comfortable and clean. Clothing treatment equipment can remove fine dust adhering to clothing, deodorize, dry, and add fragrance. In addition, clothing treatment equipment can prevent static electricity, remove wrinkles from clothing using dehumidified air or steam, and disinfect clothing.

[0005] Specifically, the garment handling equipment may include a garment support configured to agitate the garments for better removal of fine dust, wrinkle removal, and drying. In other words, the garment management equipment may include a garment support configured to allow a hanger rod for the garments to reciprocate in a predetermined direction.

[0006] Korean Patent No. 10-1285890 discloses a garment support capable of reciprocating motion. In Korean Patent No. 10-1285890, an actuator is disclosed that is configured to remove wrinkles and dust from clothing by reciprocating a hanger rod suspended for clothing. When the rotational speed of the actuator changes, the period (or frequency) of the hanger rod changes, but the actuator is able to maintain the amplitude of the hanger rod. However, given that the amplitude of the hanger rod is constant, there are physical limitations in reducing the period of the hanger rod or simply increasing the corresponding frequency.

[0007] An example of a method for controlling the process of garment processing has been disclosed in Korean Patent No. 10-1780223. However, Korean Patent No. 10-1780223 describes removing wrinkles from mounted garments by providing steam and operating a heat pump only during the drying process, and does not mention the amplitude and cycle of the hanger rod used to maximize moisture content and improve garment drying. Summary of the Invention

[0023] The clothes hanger rod can be configured to reciprocate in one of three modes: a first mode, a second mode, and a third mode. The third mode allows the clothes hanger rod to reciprocate at a third frequency between the first and second frequencies and a third amplitude depending on the third frequency, wherein the third amplitude can be greater than the first and second amplitudes.

[0024] The clothes hanger rod can be configured to reciprocate in one of the following modes: a first mode, a second mode, a third mode, and a fourth mode. The fourth mode allows the clothes hanger rod to reciprocate at a predetermined fourth frequency greater than the third frequency and a fourth amplitude depending on the fourth frequency, wherein the fourth amplitude can be less than the first amplitude, the second amplitude, and the third amplitude.

[0035] The blower fan can be configured to rotate at a first rotational speed during the steam preheating time.

[0036] The blower fan can be configured to rotate at a second rotational speed during the steam supply period.

[0037] The blower fan can be configured to rotate at a third rotational speed during standby time.

[0038] The blower fan can be configured to rotate at a fourth rotational speed during the total wrinkle removal process.

[0039] The rotational speed of the blower fan during the first wrinkle removal process may be different from at least one of the rotational speed of the blower fan during the second wrinkle removal process or the rotational speed of the blower fan during the third wrinkle removal process.

[0040] The blower fan can be configured to rotate at a fifth rotational speed during the drying process.

[0041] The blower fan can be configured to rotate as the clothes hanger rod reciprocates.

[0045] The garment handling equipment may also include a trough positioned within a hanger rod and configured to convert the reciprocating motion of a motion converter into reciprocating motion in the direction of motion. The motion converter, configured to rotate with a vibrator, may protrude from the vibrator and be inserted into the trough.

The first support rod can be connected to the first fastener and inserted into the first support through hole and the first upper connecting hole, so that the first support rod can be connected to the first end of the hanger rod, and the second support rod can be connected to the second fastener and inserted into the second support through hole and the second upper connecting hole, so that the second support rod can be connected to the second end of the hanger rod.

[0048] The clothes hanger rod may be configured to move in at least one of a first mode, a second mode, a third mode, or a fourth mode during its reciprocating motion.

[0049] The clothes hanger rod may be configured to move in at least one of a first mode, a second mode, a third mode, or a fourth mode during a process performed by the garment handling equipment, the process including: a steam supply process for supplying steam to a first chamber via a steam generator for a predetermined steam supply time; and a drying process for supplying heat-exchanged air to the first chamber via a driven heat pump for a predetermined drying process time.

[0051] Beneficial effects

[0052] As can be clearly seen from the above description, this disclosure has the following effects.

[0053] According to this disclosure, the garment handling device can change the amplitude and period of the hanger rod used to hold the garment in order to perform functions such as removing dust from the garment or removing wrinkles from the garment.

[0054] This can minimize unnecessary vibrations of the clothes hanger rod in directions other than the direction of movement.

[0055] By minimizing unwanted vibrations, the driving force (or excitation force) required to move the clothes hanger rod in the direction of motion can be effectively increased.

[0056] The performance of clothing management functions can be improved by using the amplitude and period of the hanger rods that are appropriate for each clothing management function.

[0057] Unnecessary noise and vibration can be minimized by changing the amplitude and period of the clothes hanger rod.

[0059] It can provide amplitude and cycle time suitable for a variety of garment management functions, such as removing wrinkles from garments, removing dust from garments, maximizing the moisture content of garments during steam supply, and improving garment drying.

[0060] By combining various clothing management functions, a clothing management process can be provided to improve clothing management performance.

[0061] Increasing product durability can improve user convenience and satisfaction.

[0062] It will be apparent to those skilled in the art that various modifications and variations may be made to this disclosure without departing from the spirit or scope thereof. Therefore, this disclosure is intended to cover such modifications and variations as long as they fall within the scope of the appended claims and their equivalents. Attached Figure Description

[0083] Preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The construction or control methods of the device described below are for illustrative purposes only and are not intended to limit the scope of the disclosure. The same reference numerals used herein denote the same components.

[0084] The specific terms used in this specification are for ease of description only and are not intended to limit the scope of this disclosure.

[0085] For example, expressions such as “same” and “identical” not only indicate the same state, but also indicate the state including the degree of tolerance or difference in achieving the same function.

[0086] For example, expressions indicating relative or absolute arrangement, such as “in one direction,” “along one direction,” “parallel to,” “orthogonal to,” “relative to,” “concentric to,” and “coaxial to,” not only indicate the arrangement but also indicate the state of tolerances or relative displacements of angles or distances allowed to achieve the same function.

[0087] This disclosure is described based on a spatial orthogonal coordinate system of X, Y, and Z axes that are orthogonal to each other. Each axis direction (X-axis direction, Y-axis direction, Z-axis direction) refers to the two directions along which each axis extends. Each axis direction preceded by a "+" sign (+X-axis direction, +Y-axis direction, and +Z-axis direction) refers to the positive direction of one of the two directions along which each axis extends. Each axis direction preceded by a "-" sign (-X-axis direction, -Y-axis direction, and -Z-axis direction) refers to the negative direction of the other of the two directions along which each axis extends.

[0088] The terms used herein to indicate directions such as “front (+Y), back (-Y), left (+X), right (-X), up (-Z), and down (-Z)” are defined by the X, Y, and Z coordinate axes, but these terms are used only for a better understanding of this disclosure. That is, it is obvious that directions can also be defined differently depending on where the reference is placed.

[0089] The use of terms such as "first," "second," and "third" preceding components in this document is solely for the purpose of avoiding confusion between components. That is, these terms do not imply any order, importance, or hierarchical relationship between the components. For example, an embodiment including only the second component can be implemented without the first component.

[0090] Unless the context clearly indicates otherwise, the singular form used in this article includes the plural form.

[0091] Figure 1 An example of a conventional garment handling device 1000 is shown. According to one embodiment of this disclosure, the garment handling device 1000 may include: a cabinet 10 including an entrance 11 on its front side; a first chamber 100 located inside the cabinet 10 and defining a space for holding garments through the entrance 11; a second chamber 200 located below the first chamber 100 and defining a space separate from the first chamber 100; a hanger rod 693 located in the first chamber 100 and configured to hold garments contained within the first chamber 100; and a drive 610 configured to reciprocate the hanger rod 693 based on the torque of a motor 620. The driver 610 may include: a motor 620; a vibrator 630 configured to support the motor 620 and to vibrate alternately in a first rotational direction and a second rotational direction opposite to the first rotational direction by rotation of the motor 620; and a motion converter 680 configured to rotate with the vibrator 630 and convert the vibration of the vibrator 630 to allow the hanger rod 693 to reciprocate along a predetermined direction of motion associated with the hanger rod 693. Specifically, the hanger rod 693 may reciprocate with different amplitudes and periods depending on the number of rotations of the motor 620.

[0092] The garment processing apparatus 1000 may include: a blower 220 located inside a second chamber 200 and including a fan 226 configured to draw in air from a first chamber 100 to circulate air in the first chamber 100; a compressor 234 configured to compress a refrigerant; and a heat exchanger (not shown) configured to exchange heat between the air drawn in by the blower 220 and the refrigerant. The garment processing apparatus 1000 may also include: a heat pump 230 connected to the blower 220 and configured to discharge air dehumidified and heated by the heat exchanger (not shown) into the first chamber 100; a steam generator 250 located inside the second chamber 200 and configured to generate and supply steam; a water tank 310 located in front of the second chamber 200 and configured to supply water to the steam generator 250; and a drain tank 330 located in front of the second chamber 200 and configured to store condensate generated in the first chamber 100 and the heat pump 230.

[0093] The garment handling apparatus 1000 may include a garment support 600 disposed inside a first chamber and configured to hold garments or a garment rack. The garment support 600 may include: a hanger portion 690 including a hanger rod 693 configured to hold garments or a garment rack; an actuator 610 configured to transmit power to cause the hanger portion 690 to reciprocate in a predetermined direction of motion; and a support member 670 configured to support the actuator 610.

[0094] For example, the clothes hanger rod 693 can reciprocate along the width of the cabinet 10. The length of the clothes hanger rod 693 can be shorter than the width of the cabinet 10.

[0095] The garment processing equipment 1000 may also include a blower 220 (see Figure 2 ) and heat pump 230 (see Figure 2 The blower is located inside the second chamber 200 and is configured to draw in air from the first chamber 100. The heat pump is configured to dehumidify and heat the drawn-in air and discharge the air into the first chamber 100.

[0096] The cabinet 10 can be made of metal. If strength can be maintained, the cabinet 10 can be made of plastic. The first chamber 100 can be formed by plastic injection molding. The first chamber 100 can be attached to the cabinet 10 via a frame (not shown). However, the space between the cabinet 10 and the first chamber 100, or the space between the cabinet 10 and the second chamber 200, can be filled with foamed plastic such as polyurethane.

[0097] The first chamber 100 may be configured to contain clothing, including upper and lower garments, and the blower 220 (see Figure 2 ), heat pump 230 (see) Figure 2 ) and steam engine 250 (see Figure 2The blower 220 can be located inside the second chamber 200 and is configured to keep clothes fresh. In other words, the blower 220 located inside the second chamber 200 (see...) Figure 2 ), heat pump 230 (see) Figure 2 ) and steam engine 250 (see Figure 2 It can be configured to disinfect and deodorize clothing, remove wrinkles, and dry clothing by using steam and / or heated air.

[0098] The first chamber 100 may include a garment support 405 configured to hold garments on the upper part of the first chamber 100. The garment support 405 may accommodate a hanger for the garments. The garment support 405 includes: a hanger portion 690 configured to agitate garments placed therein; a actuator 610 configured to reciprocate the hanger portion 690; and a support member 670 configured to support and secure the garment support to the cabinet 10. The hanger portion 690 may include: a hanger rod 693 disposed along the width direction of the cabinet 10 and configured to hold a hanger H1; and a hanger rod support member 691 configured to movably support both ends of the hanger rod. The hanger rod 693 may include a hanger recess 6931 in the form of a groove for suspending the hanger.

[0099] For example, the driver 610 can be configured to convert the rotation of the motor 620 disposed in the driver 610 into vibrations that alternately rotate in first and second rotational directions opposite to each other. A motion transducer can be configured to convert this vibration into reciprocating motion of the hanger rod 693, which will be described in detail below. The rotation of the driver 610 can agitate the garments T mounted on the hanger rod 693. Therefore, the garment handling device 1000 can be configured to agitate the garments mounted on the garment support 405 to perform garment management functions such as removing foreign matter, including dust attached to the garments, maintaining the texture of the garments (such as hair), and removing wrinkles from the garments.

[0100] In particular, the garment handling device 1000 may be configured to expose the garments, which are mounted on the garment support 405, to steam or moisture supplied from the second chamber 200 when the garments are shaken, thereby performing the garment management function more effectively. Figure 1 The clothing support 405 is shown by a circle indicated by a dotted line. The clothing support 600 can be referred to as a movable clothes hanger. In a narrower sense, the clothing support can be referred to as a reciprocating clothes hanger rod.

[0101] That is, when the garment is hung on the garment support 405, the garment can be suspended inside the first chamber 100 by its own weight in the unfolded state. Multiple hanger recesses 6931 can be arranged at predetermined intervals at the hanger rod 693, so that the surface of the garment can be evenly exposed to the dehumidified and heated air and / or steam supplied from the second chamber 200.

[0102] Water typically boils at 100°C under atmospheric pressure, and the resulting water vapor can be called steam. Moisture refers to the state of water droplets 1 mm or smaller suspended in the air at room temperature. For example, moisture is similar to fog. Generally, considering that steam generated by heating and boiling water has a higher bactericidal ability than moisture due to its high temperature, and that water molecules move more actively at high temperatures, steam can be more penetrating than moisture, making steam more suitable than moisture when refurbishing clothes.

[0103] The first chamber 100 may be defined by: a first chamber upper surface 101 disposed below the actuator 610 of the clothing support 405; a first chamber bottom surface 102 defining a bottom; a first chamber side surface 103 defining a side surface of the first chamber 100 and configured to connect the first chamber upper surface 101 and the first chamber bottom surface 102; and a first chamber rear surface. If the surface where the inlet 11 is formed is the front surface, the rear surface of the first chamber may be located in the opposite direction.

[0104] The following components may be disposed on the bottom surface 102 of the first chamber: an air supply port 111 and a steam supply port 112, configured to supply steam generated by a steam engine 250 in the second chamber 200 and air dehumidified and heated by a heat pump 230 in the second chamber 200 to the first chamber 100; and an air inlet port 115, configured to draw air from the first chamber 100 by a blower 220.

[0105] The air inlet port 115 can be configured to discharge condensate from the first chamber 100, where water is generated when steam in the first chamber 100 condenses. That is, condensate generated on the inner circumferential surface of the first chamber 100 can flow or fall to the bottom surface 102 of the first chamber due to its own weight. Since the bottom surface 102 of the first chamber is inclined toward the air inlet port 115, the condensate can naturally move toward the air inlet port 115. Therefore, the condensate discharged to the air inlet port 115 can flow downwards through the inlet pipe 221 (see...). Figure 2 The contents are then temporarily stored in a storage tank (not shown) located on the lower inner side of the inlet pipe 221.

[0106] Similarly, condensate generated on the inner surface 401 of the door 400 can fall along the door liner 420 disposed on the inner surface 401 to the bottom surface of the first chamber and be discharged into a storage tank (not shown) through the air inlet port 115. The condensate collected in the storage tank can be drained by a drain pump 339 (see [link to relevant documentation]). Figure 2 It is discharged into and collected in drain tank 330.

[0107] Reference Figure 1Air supply port 111 and steam supply port 112 may be located in the region where the bottom surface 102 of the first chamber meets the rear surface of the first chamber 100. Furthermore, the region where the bottom surface 102 of the first chamber meets the rear surface of the first chamber may have a smoothly sloping shape.

[0108] The air inlet port 115 can be located on the bottom surface 102 of the first chamber near the inlet 11. Therefore, a circulation structure can be formed in which air in the first chamber 100 is discharged through the air supply port 111 and drawn back in through the air inlet port 115. Steam can also be discharged through the steam supply port 112, condensed, and drawn in through the air inlet port 115, and subsequently collected in a storage tank (not shown) configured to store condensate.

[0109] In order to discharge the water condensed in the first chamber 100 into the second chamber 200 more smoothly through the air inlet port 115, the bottom surface 102 of the first chamber can be downward from the rear surface of the first chamber 100 along the direction of the air inlet port 115.

[0110] like Figure 1 As shown, a water supply tank 310 configured to supply water to the steam engine 250 and a drain tank 330 configured to discharge condensate collected in a storage tank (not shown) can be disposed in the front of the second chamber 200. Furthermore, a tank module frame can be provided, configured to define a tank mounting space 351 in which the water supply tank 310 and the drain tank 330 are installed, such that the tank mounting space 351 is separated from the second chamber 200. That is, the tank mounting space 351 and the second chamber 200 are located below the first chamber 100, and the tank mounting space 351 can be located closer to the door 400 than the second chamber 200. The second chamber 200 can be located behind the tank mounting space 351.

[0111] Each of the water supply tank 310 and the drain tank 330 may be configured to be detachable from the tank module frame (not shown). Alternatively, the water supply tank 310 and the drain tank 330 may be integrated together, allowing both the water supply tank 310 and the drain tank 330 to be detached simultaneously.

[0112] Door 400 may include an inner door surface 401 located on the rear surface of door 400, or the inner door surface may be located in a direction from door 400 to first chamber 100 when door 400 is closed. Door 400 may be rotatably connected to cabinet 10 by means of hinges to open and close entrance 11, for which door 400 may include door hinges 411 and 412 for rotatable connection.

[0113] When the door 400 is closed by the user, the front surfaces of the water supply tank 310 and the drain tank 330 can face the inner surface 401 of the door. When the door 400 is opened by the user, the front surfaces of the water supply tank 310 and the drain tank 330 can be exposed to the outside.

[0114] The front surface of each of the water supply tank 310 and the drain tank 330 may be made of a transparent or translucent light-transmitting material. When the user opens the door 400, the user can immediately check the water level of the water supply tank 310 and the drain tank 330. In some embodiments, the water supply tank 310 and the drain tank 330 may include a water supply tank window (not shown) and a drain tank window (not shown) respectively on their front surfaces, allowing the user to check the water level of the water supply tank 310 and the drain tank 330.

[0115] The water supply tank handle 315 and the drain tank handle 335 can be respectively included on the front surface of the water supply tank 310 and the drain tank 330. When the user pulls the water supply tank handle 315 and the drain tank handle 335, the water supply tank 310 and the drain tank 330 can rotate relative to the front end of the water supply tank 310 and the front end of the drain tank 330, respectively, so that the water supply tank 310 and the drain tank 330 can be separated from the tank module frame (not shown). When the water supply tank 310 and the drain tank 330 are mounted on the tank module frame (not shown), the water supply tank 310 and the drain tank 330 can also be rotated and positioned on the tank module frame (not shown).

[0116] Door 400 may also include a sealing portion 430 and a door liner 420, the sealing portion being configured to prevent damage from steam engine 250 (see also...). Figure 2 The steam leakage supplied to the first chamber 100 is addressed by the door liner being disposed on the inner surface 401 of the door and configured to guide condensate generated on the inner surface 401 of the door to be discharged through the air inlet port 115.

[0117] The seal 430 may be configured to seal the space between the door 400 and the cabinet 10 when the door 400 is closed, thereby preventing steam or condensate from leaking to the outside. The seal 430 may surround the edge of the inner surface 401 of the door. The seal 430 may be configured to perform the function of mitigating the impact between the cabinet 10 and the door 400 when the door 400 is closed.

[0118] The sealing part 430 may include a first washer 431 having a size corresponding to the front surface of the first chamber 100 in the inner surface 401 of the door and a second washer 432 having a size corresponding to the front surface of the box mounting space 351 in the inner surface 401 of the door, in which a water supply box 310 and a drain box 330 are installed.

[0119] The first gasket 431 may be configured to seal the first chamber 100 and prevent condensate generated in the first chamber 100 and the inner surface 401 of the door from flowing into the enclosure mounting space 351. The second gasket 432 may be positioned below the first gasket 431 and configured to prevent steam or moisture from leaking to the outside through the enclosure mounting space 351.

[0120] The first washer 431 may include a lower washer 4311 disposed in the width direction of the door 400 and configured to seal the lower portion of the first chamber 100. The second washer 432 may include an upper washer 4321 disposed in the width direction of the door 400 and configured to seal the upper portion of the housing mounting space 351. The lower washer 4311 and the upper washer 4321 may be positioned between the first chamber 100 and the housing mounting space 351 to contact the front portion 119 facing the inner surface 401 of the door.

[0121] The door liner 420 can be attached to the inner surface 401 of the door and configured to guide condensate generated on the inner surface 401 into the air intake port 115. Specifically, the door liner 420 can be configured such that it slopes towards the bottom of the inner surface 401 and has a protruding shape. The lower end of the door liner 420 protrudes from the inner surface 401, positioning it above the air intake port 115. Therefore, condensate flowing downwards along the door liner 420 can be directly discharged from the lower end of the door liner 420 into the air intake port 115.

[0122] In some cases, condensate falling from the door liner 420 toward the bottom surface 102 of the first chamber can be guided by a separate guide member provided on the bottom surface 102 of the first chamber and discharged to the air inlet port 115.

[0123] After the trousers (trousers P) are hung on the trouser rack H2, the clothing support 405 configured to hold the trouser rack H2 and the compression unit 500 configured to compress the trousers P fixed by the clothing support 405 can be located on the inner surface 401 of the door or inside the first chamber 100.

[0124] The reason why pants P are hung upside down, i.e., the bottom of pants P is upward, is that the weight of the waist of pants P, i.e. the upper part of pants P, is greater than the weight of the legs of pants P, i.e. the lower part of pants P, so pants P is evenly spread out by the weight of pants P.

[0125] The compression unit 500 may include a base plate 520 coupled to the inner surface 401 of the door and configured to support clothing, and a pressure plate 510 configured to rotate toward the base plate 520 and compress the pants P.

[0126] For this purpose, the extrusion unit 500 may also include an extrusion unit hinge 518 and a pressure plate retainer 519, the extrusion unit hinge being configured to hingely connect the pressure plate 510 and the base plate 520 to allow the pressure plate 510 to rotate, and the pressure plate retainer being configured to combine and fix the pressure plate 510 and the base plate 520.

[0127] After placing the trousers P between the pressure plate 510 and the bottom plate 520, by closing the door 400 and exposing the trousers P to steam and hot air, the wrinkles of the trousers P can be removed and sharp creases can be formed in the trousers P.

[0128] For this purpose, steam must easily penetrate the trousers P, and therefore a steam penetration hole 515 configured to penetrate the pressure plate 510 may be included. Furthermore, to prevent the seam, which is provided along the longitudinal direction of the trousers, from being squeezed, a first recess 516 and a second recess 517 may be defined above and below the steam penetration hole 515 on the surface of the pressure plate 510 that contacts the trousers P, respectively.

[0129] The base plate 520 may be made of an elastic material to support the clothing to be squeezed. Alternatively, the base plate 520 may also include an elastic member configured to elastically support the base plate 520 within the door 400.

[0130] To prevent the pants P from being pushed when the pressure plate 510 is rotated to the base plate 520 after the pants P is suspended on the garment support 405, the garment fastener 540 can be further disposed in the lower part of the base plate.

[0131] The garment fastener 540 may be provided in the form of a rod. Specifically, the garment fastener 540 may be spaced a predetermined distance from the bottom of the base plate 520. In this case, the height of the pressure plate 510 is higher than the height of the base plate 520, so that the garment fastener 540 can be covered when the pressure plate 510 is rotated to the base plate 520.

[0132] Figure 1 An example is shown in which the garment fastener 540 is arranged in the form of a long rod and configured to secure garments at one end by rotation. However, the garment fastener 540 may be arranged in the form of a clip, such that the garment fastener 540 is positioned at both ends of the compression unit 500 to secure the sides of the trousers P.

[0133] The compression unit 500 may include a side fastener 530 positioned between the base plate 520 and the door liner 420 and configured to prevent trousers P hanging on the garment fastener 540 from swinging to the side.

[0134] Reference Figure 2(a) The second chamber 200 may include: a blower 220 configured to draw in air from the first chamber 100; a steam generator 250 configured to generate steam by receiving water from a water supply tank 310 and to supply the steam to the first chamber 100; and a heat pump 230 configured to dehumidify and heat the air drawn in by the blower 220 and to discharge the air to the first chamber 100. The steam generator 250, the blower 220, and the heat pump 230 may be mounted on a base 210.

[0135] A support member 280 configured to support the steam engine 250 and the heat pump 230 can be connected to the base 210. The support member 280 may include a first support member 281 positioned closer to the blower 220 and a second support member 282 positioned further away from the blower 220.

[0136] The heat pump 230 may be located on the upper part of the support 280, and the steam engine 250 may be positioned inside the support 280, and more specifically, in the receiving area S formed between the support 280 and the base 210. A controller 270 configured to control the blower 220, the steam engine 250, and the heat pump 230 may be located in the receiving area S.

[0137] However, this is merely an example. The controller 270 may be located at the rear of the second chamber 200. When the controller 270 is located at the rear of the second chamber 200, the controller 270 can be removed via a rear panel (not shown) that is connected to the second chamber 200 and located on the rear surface of the cabinet 10.

[0138] The controller 270 can also be configured to control the compression unit 500, as will be described below. Furthermore, the controller 270 can be configured to control the reciprocating motion of the garment support 600 (see [link to relevant documentation]). Figure 1 ).

[0139] The steam generator 250 may be configured to disinfect and deodorize clothing installed in the first chamber 100 and remove wrinkles from the clothing. The blower 220 and the heat pump 230 may be configured to circulate air in the first chamber 100 and dehumidify the first chamber 100 by heat exchange.

[0140] Reference Figure 2 (b) The blower 220 may include a blower fan 226 and an inlet duct 221. Assuming the inlet 11 is oriented forward and the rear surface of the first chamber is oriented backward, the inlet duct 221 may be positioned in front of the blower fan 226, and the housing module frame may be positioned in front of the inlet duct 221. Therefore, the housing module frame can form a housing mounting space 351, and the housing mounting space 351 can be separated from the second chamber 200.

[0141] The water supply tank 310 and drain tank 330, mounted on the cabinet module frame, can be located on one side of the cabinet 10. For example, the water supply tank 310 can be located in the cabinet mounting space 351 closer to the right side of the cabinet 10 than the left side. The drain tank 330 can be located in the cabinet mounting space 351 closer to the left side of the cabinet 10 than the right side.

[0142] Similar to the water tank 310, the steam engine 250 can be positioned within the second chamber 200 closer to the right side of the cabinet 10 than the left side. This is to simplify the connection path through which water moves from the water tank 310 to the steam engine 250 by placing the steam engine 250 behind the water tank 310.

[0143] The steam engine 250 may include a reservoir 251 configured to store water and a heater 2501 located inside the reservoir 251 and configured to heat the water. Additionally, the steam engine 250 may include a steam temperature sensor 9131 configured to measure the temperature of the water stored in the reservoir 251.

[0144] The heater 2501 may be configured to heat water stored in the reservoir 251. Steam generated by heating the water may be supplied to the first chamber 100 along a steam flow path (not shown) through a steam supply port 112 provided on the bottom surface 102 of the first chamber.

[0145] The water supply tank 310 can be configured to supply water for use to the steam engine 250. When the water supply tank 310 is placed in the tank mounting space 351, a water supply check valve (not shown) provided on the bottom surface of the water supply tank 310 can be opened, and water can be supplied to the storage tank 251 through the water supply path connected to the water supply check valve.

[0146] If the water supply tank 310 is located closer to the left side of the cabinet 10 than the right side of the cabinet 10, then the steam engine 250 can be located closer to the left side of the cabinet 10 than the right side of the cabinet 10. This is to reduce the length of the water supply path (not shown) connecting the water supply tank 310 and the steam engine 250 and to simplify the water supply path as much as possible.

[0147] To circulate air in the first chamber 100, the blower 220 may be configured to draw in air through an air inlet port 115 and an inlet duct 221 located on the bottom surface 102 of the first chamber 100. The inlet duct 221 may include an air inlet duct inlet 2213 with a shape corresponding to the air inlet port 115, an inlet duct body 2211 configured to move the drawn-in air to the blower 226, and an inlet duct outlet 2215 connected to the inlet of the blower 226.

[0148] As a centrifugal blower, blower 226 can be configured to discharge the drawn-in air based on centrifugal force. Blower 226 can be connected to heat pump 230 through blower housing 224. Therefore, the air drawn in by blower 226 can flow into air inlet 2311 of duct housing 231, which is connected to blower outlet 2242 of blower housing 224.

[0149] The heat pump 230 may include: a duct housing 231, which serves as a path through which air moves; an air inlet 2311, located at one end of the duct housing 231 and configured to draw in air from the blower fan 226; and an air outlet 2312, located at the other end of the duct housing 231 and configured to discharge air into the first chamber (100).

[0150] The heat pump 230 may also include a first heat exchanger (not shown) and a second heat exchanger (not shown) located inside the pipe housing 231 to exchange heat with the intake air. The heat pump 230 may also include a compressor 234 located outside the pipe housing 231 and configured to compress and circulate the refrigerant, and to supply the refrigerant to the first and second heat exchangers.

[0151] Compressor 234 can be located on one side of support 280. Since the water tank 310 in the second chamber 200 is located near the first side of cabinet 10, and the steam engine 250 and support 280 are also located near the first side of cabinet 10, compressor 235 can be located closer to the second side of cabinet 10 than the first side of cabinet 10. For example, refer to… Figure 2 (b) The compressor 235 may be located closer to the right (closer to the right side of the cabinet 10 than the left side of the cabinet 10), and the support 280 and the steam engine 250 may be located closer to the left (closer to the left side of the cabinet 10 than the right side of the cabinet 10).

[0152] The inlet pipe 221 may include an inlet pipe inlet 2213, which is connected to an air inlet port 115 disposed on the bottom surface 102 of the first chamber 100 and configured to draw in air from the first chamber 100. The inlet pipe inlet 2213 may form an inclined flow path. This allows condensate generated in the first chamber 100 and the door 400 to move along the inclined flow path through the inlet pipe inlet 2213 connected to the bottom surface 102 of the first chamber 100 to a reservoir (not shown) disposed on the lower inner side of the inlet pipe 221.

[0153] The inlet pipe 221 can be positioned in front of the blower 226, and the steam engine 250 and heat pump 230 can be positioned behind the blower 226. Furthermore, the heat pump 230 can be supported by a support member 280. The support member 280 can be connected to a base 210 defining the bottom of the second chamber 200. Therefore, the support member 280 can form a predetermined distance between the base 210 and the heat pump 230, and more specifically, a receiving area S is formed between the support member 280 and the base 210.

[0154] The steam engine 250 can be positioned in the receiving area S and connected to the support 280 in the receiving area S. The steam engine 250 can be spaced apart from the base 210 and connected to the support 280.

[0155] However, with Figure 2 Unlike (b), blower 220 may be disposed inside pipe housing 231 to circulate air in first chamber 100. Alternatively, blower 220 may be installed between air outlet 2312 and second heat exchanger (condenser).

[0156] Condensate is generated in the pipe housing 231 through heat exchange between the first heat exchanger (evaporator) and the intake air. The condensate generated by the heat pump 230 can move through the bottom surface of the pipe housing 231 to a storage tank (not shown) and be discharged into a drain tank 330.

[0157] Air and / or steam supplied by heat pump 230 and steam engine 250 can be applied to clothing contained in the first chamber 100, and the air and / or steam can affect the physical or chemical properties of the clothing. For example, the fabric structure of the clothing can be relaxed by hot air or steam, thereby not only removing wrinkles but also removing unpleasant odors based on the reaction between steam and odor molecules on the clothing. Furthermore, the hot air and / or steam supplied by heat pump 230 and steam engine 250 can disinfect parasitic bacteria on the clothing.

[0158] Figure 3 (a) shows an example of a garment support. The garment support 700 may include: a hanger portion 790 on which garments are suspended; an actuator 710 configured to agitate the suspended garments by reciprocating the hanger portion 790; and a support member 670 configured to support and secure the actuator 710 to the support frame 15.

[0159] The hanger portion 790 may include: a hanger rod 793 configured to hold clothing; a plurality of hanger recesses 7931 disposed in the hanger rod 793 and configured to hold a hanger H1; and hanger rod supports 7911 and 7912 configured to support the two ends of the hanger rod 793.

[0160] When it is said that clothing is hung on the hanger rod 793, it means that the hanger H1 used to hold the clothing is installed in the hanger groove 7931. However, unlike this, clothing can also be hung directly on the hanger rod 793. In this case, the hanger rod 793 can be used as a clothing hanging rod.

[0161] The drive 710 can be located between the first chamber 100 and the cabinet 10, so that the drive 710 is not exposed from the first chamber 100. For this purpose, the garment handling apparatus may also include a support frame 15 configured to receive and support the drive 710. Only the hanger rod supports 7911 and 7912, configured to support the two ends of the hanger rod 793, can pass through the support frame 15 and be inserted into the first chamber 100.

[0162] The drive 710 may include a motor 720 configured to generate torque. When the motion converter 780 converts the rotation of the motor 720 into linear motion along the width of the cabinet 10, the clothes hanger rod 793 may move along the width of the cabinet 10. If the rotation direction of the motor 720 changes alternately, the clothes hanger rod 793 may reciprocate along the width of the cabinet 10.

[0163] Figure 3 (b) shows a rack 782 and pinion 781 as an example of a motion converter 780, with the pinion connected to a motor 720 and configured to rotate. However, this is merely an example, and the motion of the driver 710 can be converted into the reciprocating motion of the hanger rod 793 in other ways. For example, the driver 710 can be configured as an actuator capable of linear reciprocating motion. In this case, a motion converter may not be necessary. Alternatively, the driver 710 may include a linear motor and control the direction of motion of the linear motor to achieve the reciprocating motion of the hanger rod 793. Alternatively, to convert the rotation of the motor into linear reciprocating motion, a rotating plate can be provided on the rotating shaft of the motor. Specifically, the rod can be connected to a portion offset from the center of rotation of the rotating plate, and the rotation of the motor can be converted into the reciprocating motion of the rod.

[0164] Reference Figures 4 to 10 The clothing support 600 can be disposed on the upper part of the cabinet 10. Specifically, the drive 610 can be positioned between the upper panel 12 defining the upper surface of the cabinet 10 and the upper surface 101 of the first chamber. A support frame 15 configured to support the drive 610 can be positioned between the upper panel 12 and the upper surface 101 of the first chamber. The clothing support 600 can be supported by the support frame 15.

[0165] Reference Figure 4The support frame 15 can form a support space 15S configured to accommodate the clothing support 600. The support space 15S can be formed by a recess in the support frame 15. The support frame 15 can be used as a support for mounting a lighting device (not shown) configured to illuminate the interior of the first chamber 100.

[0166] The garment support 600 may include a hanger portion 690 and an actuator 610. The hanger portion 690 may include a hanger rod 693 for holding garments and hanger rod supports 691 movably connected to the support frame 15 and configured to support both ends of the hanger rod 693. The actuator 610 may generate power for reciprocating motion of the hanger rod 693. For this purpose, the actuator 610 may include: a motor 620; a vibrator 630 configured to support the motor 620 and vibrate alternately in clockwise and counterclockwise directions by rotation of the motor 620; and a motion converter 680 configured to rotate with the vibrator 630 and convert the vibration of the vibrator 630 to allow the hanger rod 693 to reciprocate along a predetermined direction of motion associated with the hanger rod 693.

[0167] The hanger section 690 can be configured to hold clothing or hangers. The hanger section 690 can be supported by the circumferential surface of the cabinet 10 and the first chamber 100 or the support frame 15. Figure 4 An example is shown where the hanger section 690 is supported by the support frame 15. The hanger section 690 can be connected to the driver 610 to receive vibrations from the driver 610. The vibrations generated by the driver 610 can be converted into arc reciprocating motion by the motion converter 680, and subsequently into linear reciprocating motion of the hanger rod 693.

[0168] Figure 5 (a) to Figure 5 (c) is a top view of the support frame 15, the actuator 610, and the upper surface 101 of the first chamber.

[0169] Figure 5 (a) is a top view of the clothing support 600 supported by the support frame 15. Therefore, Figure 5 (a) primarily shows the driver 610. The driver 610 may include a motor 620 positioned at the center and eccentric portions 634 disposed on both sides of the motor 620 (see Figure 1). Figure 5 The eccentric portion 634 can be connected to the vibrator 630 to rotate together. Furthermore, the vibrator 630 can be configured to rotatably support a motor shaft 625 that rotates by torque generated by the motor 620.

[0170] The eccentric portion 634 can rotate relative to the first rotation axis Ow1 and the second rotation axis Ow2, respectively. The eccentric portion 634 can be connected to the vibrator 630. The motion converter 680 can protrude toward the hanger rod 693 and extend along the connecting axis Oh toward the first chamber 100.

[0171] The support member 670 can be fixed to the cabinet 10 and the support frame 15. The support member 670 can be configured to support the actuator elastic member 635. Furthermore, the support member 670 can be configured to support the actuator 610. That is, the support member 670 can be configured to rotatably support the actuator 610. Specifically, the support member 670 can be configured to rotatably support the actuator 610 relative to the central axis Oc.

[0172] The hanger portion 690 may also include a hanger rod support 691, which is configured to allow reciprocating movement at both ends of the hanger rod 693. Furthermore, the hanger portion 690 may also include a support rod retainer 697, which is configured to rotatably connect the hanger rod support 691 to the support frame 15.

[0173] Figure 5 (b) shows the support frame 15. The support frame 15 may include a support space 15S configured to accommodate the drive 610. The support space 15S can be formed by recessing the support frame 15 toward the first chamber 100. A central through hole 153 penetrating along the height direction of the cabinet 10 may be provided on the bottom surface of the support space 15S. This is for inserting the motion converter 680 and connecting the hanger rod 693.

[0174] Furthermore, an illumination through-hole 154 for mounting an illumination device configured to illuminate the first chamber 100 may be further provided on the bottom surface of the support space 15S.

[0175] On both sides of the support space 15S, a first support through hole 151 and a second support through hole 152 penetrating along the height direction of the cabinet 10 can be respectively provided, so that the clothes hanger rod support 691 can be rotatably connected and fixed. The first support rod 6911 and the second support rod 6912, which are configured to support the two ends of the clothes hanger rod 693, can be inserted into the first support through hole 151 and the second support through hole 152 respectively. The first support rod 6911 and the second support rod 6912 can be connected to the support frame 15 through the first fastener 6971 and the second fastener 6972 respectively.

[0176] Figure 5(c) is a top view corresponding to the upper surface 101 of the first chamber of the support frame 15. The motion converter communication hole 1013, the chamber lighting communication hole 1014, the first upper communication hole 1011, and the second upper communication hole 1012, which are respectively associated with the central through hole 153, the lighting through hole 154, the first support through hole 151, and the second support through hole 152, can be formed by penetrating the upper surface 101 of the first chamber along the height direction of the cabinet 10.

[0177] That is, the motion converter communication hole 1013 can be formed by penetrating the upper surface 101 of the first chamber, so that the motion converter 680 inserted through the central through hole 153 can be inserted into the first chamber 100. Similarly, the chamber lighting communication hole 1014 can be configured to insert a lighting device (not shown). In addition, the first support rod 6911 and the second support rod 6912 can be inserted into the first chamber 100 through the first upper communication hole 1011 and the second upper communication hole 1012, respectively, and connected to both ends of the hanger rod 693.

[0178] Figure 6 This is a cross-sectional view of the clothing support 600 as seen from one side of cabinet 10. (Refer to...) Figure 5 (c) and Figure 6 A portion of the garment support 600 may be positioned between the top plate 12 and the upper surface 101 of the first chamber. In particular, the support frame 15 may be positioned between the upper surface 101 of the first chamber and the top plate 12, and the support frame 15 may include a support space 15S for accommodating a portion of the garment support 600.

[0179] The garment handling equipment may further include: a first support rod 6911 and a second support rod 6912, configured to support the end of the hanger rod 693 in a manner that allows the hanger rod 693 to reciprocate; a support frame 15, positioned between the first chamber 100 and the upper panel 12 and configured to support the actuator 610; a first retainer 6971 and a second retainer 6972, configured to rotatably support the first support rod 6911 and the second support rod 6912 within the support frame 15; and a first chamber upper surface 101, defining the upper surface of the first chamber 100. The support frame 15 may include: a central through-hole 153, passing through the support frame 15 along the height direction of the cabinet 10; and a first support through-hole 151 and a second support through-hole, positioned in opposite directions along the width direction of the cabinet 10 relative to the central through-hole 153 and penetrating the support frame 15 along the height direction of the cabinet 10. The upper surface 101 of the first chamber may further include: a motion converter connecting hole 1013, corresponding to the central through hole 153 and penetrating the upper surface 101 of the first chamber; and a first upper connecting hole 1011 and a second upper connecting hole 1012, respectively corresponding to the first support through hole 151 and the second support through hole 152 and penetrating the upper surface 101 of the first chamber. A first support rod 6911 can be connected to a first fastener 6971 and inserted into the first support through hole 151 and the first upper connecting hole 1011, so that the first support rod 6911 can be connected to the first end of the hanger rod 693. A second support rod 6912 can be connected to a second fastener 6972 and inserted into the second support through hole 152 and the second upper connecting hole 1012, so that the second support rod 6912 can be connected to the second end of the hanger rod 693.

[0180] Reference Figure 6 The hanger portion 690 may also include a slot 694 positioned on the hanger rod 693 and configured to convert the reciprocating motion of the motion converter 680 into reciprocating motion in the direction of motion. Furthermore, a slot cover 695 may be included, which not only protects the slot 694 and the motion converter 680 but also prevents the slot 694 and the motion converter 680 from being exposed to the user.

[0181] The motion converter 680 can be configured to rotate together with the vibrator 630 when the vibrator 630 rotates, and protrude from the vibrator 630 of the driver 610 to insert into the slot 694. Thus, the motion converter 680 can cause the hanger rod 693 to reciprocate.

[0182] Reference Figure 6 A portion of the clothing support 600, such as the hanger rod 693, may be exposed inside the first chamber 100. This is to conceal the complex construction of the actuator 610 and simplify the design of the first chamber 100 exposed to the user.

[0183] The support member 670 can be fixed to the support frame 15. The support member 670 can be configured to support the actuator elastic member 635 and also support the actuator 610.

[0184] Reference Figure 7 The hanger portion 690 may include a hanger rod 693 configured to hold clothing or hangers. In this embodiment, the hanger rod 693 may include a hanger recess 6931 configured to hold hangers. However, in another embodiment, the hanger rod 693 may include hooks (not shown) for directly hanging clothing.

[0185] The actuator 610 may be configured to cause the hanger rod 693 to reciprocate (vibrate). The actuator 610 may be connected to the hanger rod 693 and configured to transmit the vibration of the actuator 610 to the hanger rod 693.

[0186] The coat hanger rod 693 can be supported by the support frame 15. For example, the end of the coat hanger rod 693 can be connected to the support frame 15 via a coat hanger rod support 691. The coat hanger rod 693 can be configured to move relative to the cabinet 10, the support frame 15, or the first chamber 100. The coat hanger rod 693 can be configured to vibrate and reciprocate along a predetermined vibration or motion direction (+X, -X). The coat hanger rod 693 can be configured to vibrate relative to the cabinet 10 along the vibration direction (+X, -X).

[0187] That is, the actuator 610 can be configured to reciprocate the hanger rod 693 along the vibration direction (+X, -X). The hanger rod 693 can reciprocate while suspended from the upper part of the first chamber 100.

[0188] The hanger rod 693 can extend along the vibration direction (+X, -X), i.e., along the width of the cabinet 10. However, the extension length can be shorter than the width of the cabinet 10. A plurality of hanger recesses 6931 can be provided on the upper surface of the hanger rod 693. The plurality of hanger recesses 6931 can be spaced apart from each other along the vibration direction (+X, -X). Each of the hanger recesses 6931 can extend in a direction transverse to the vibration direction (+X, -X) (+Y, -Y) or along the depth direction of the first chamber 100.

[0189] The hanger portion 690 may include a hanger rod support 691 configured to movably support the end of the hanger rod 693. That is, the hanger rod support 691 may be configured to move along the vibration direction or the motion direction (+X, -X). Furthermore, the hanger rod support 691 may be made of a flexible material to allow movement of the hanger rod 693. The hanger rod support 691 may include an elastic member that can elastically deform as the hanger rod 693 moves. The upper end of the hanger rod support 691 may be connected to the support frame 15, while the lower end of the hanger rod support 691 may be connected to the first end of the hanger rod 693. For this purpose, the hanger rod support 691 may include: a first support rod 6911 connected to the first end of the hanger rod 693; and a second support rod 6912 connected to the second end of the hanger rod 693.

[0190] The upper end of the clothes hanger rod support 691 can be rotatably or movably connected to the support frame 15 via a support rod retainer 697. The support rod retainer 697 may include a first retainer 6971 and a second retainer 6972. The first retainer 6971 and the second retainer 6972 can be connected to the upper ends of the first support rod 6911 and the second support rod 6912, respectively, to connect to the support frame 15.

[0191] The upper end of the clothes hanger rod support 691 can be suspended from the support rod holder 697. The support rod holder 697 can be formed in the shape of a horizontal plate, and the support rod holder 697 can pass through the upper end of the clothes hanger rod support 691.

[0192] A hanger rod support 691, configured to connect the support rod retainer 697 and the hanger rod 693, can be disposed within a support guide 692 having an empty tube shape. The support guide 692 may include a first support guide 6921 and a second support guide 6922. Therefore, the first support rod 6911 can pass through the interior of the first support guide 6921 and connect the first retainer 6971 and the first end of the hanger rod 693. The second support rod 6912 can pass through the interior of the second support guide 6922 and connect the second retainer 6972 and the second end of the hanger rod 693.

[0193] The support rod retainer 697 can be located between the upper surface 101 of the first chamber and the support frame 15. Due to the formation of the support space 15S, the support frame 15 can define a predetermined guide space (not shown) between the upper surface 101 of the first chamber and the support frame 15 in the direction from the support space 15S to the side of the support frame 15. If the support guide 692 is provided in the guide space, steam leakage from the first chamber 100 to the actuator 610 can be prevented. For this purpose, a seal can be made between the upper surface of the support guide 692 and the hanger rod support 691. The predetermined guide space between the upper surface 101 of the first chamber and the support frame 15 can be maintained. The support guide 692 can guide the position of the hanger rod support 691. This is because the hanger rod support 691 can move inside the support guide 692 in the vibration direction (+X, -X).

[0194] The hanger rod support 691 can penetrate the support guide 692 vertically. The horizontal length of the hanger rod support 691 along the direction (+X, -X) can be shorter than the vertical length of the hanger rod support 691 along the direction (+Y, -Y) perpendicular to the vibration direction (+X, -X).

[0195] The drive 610 may include a motion converter 680 connected to the hanger portion 690. In particular, the hanger rod 693 may include a slot 694 connected to the motion converter 680. Furthermore, the hanger rod 693 may include a slot cover 695 configured to protect the slot 694.

[0196] Referring to an enlarged cross-sectional view of the slot cover 695, the slot 694 may include a slit-shaped inner slot space 6941 extending transversely to the vibration direction (+X, -X) in a direction (+Y, -Y). A motion converter 680 may protrude parallel to the central axis Oc, as will be described below, and be inserted into the slot 694 such that the motion converter 680 can be located within the inner slot space 6941.

[0197] In this embodiment, the slot 694 can form an inner slot space 6941 in the form of a slit extending in the direction (+Y, -Y), and the motion converter 680 can protrude downward and be inserted into the slot 694. However, referring to... Figure 10 The motion converter 680 can be coupled to the driver 610, allowing the motion converter 680 to rotate together with the driver 610. That is, the motion converter 680 can be coupled to the vibrator 630, allowing the motion converter 680 to rotate integrally. Therefore, the motion converter 680 can be configured to vibrate and reciprocate along an arc when the driver 610 vibrates.

[0198] The motion converter 680 may include: a rotating protrusion 6811 protruding from the vibrator 630 toward the first chamber 100 in a direction parallel to the central axis Oc; a connecting protrusion 6813 inserted into a groove 694 in a direction parallel to the central axis Oc and located in an inner groove space 6941; and a connecting rod 6812 configured to connect the rotating protrusion 6811 and the connecting protrusion 6813. Either the connecting protrusion 6813 or the rotating protrusion 6811 may extend along a connecting axis Oh parallel to the central axis Oc. Therefore, one of the connecting protrusion 6813 or the rotating protrusion 6811 may be disposed on the connecting axis Oh.

[0199] The slot 694 can extend in a direction (+Y, -Y) orthogonal to the vibration direction (+X, -X) of the clothing support 600. When the motion converter 680 is inserted into the slot 694 and rotates relative to the central axis Oc, the motion converter 680 can move relative to the slot 694 in the direction (+Y, -Y).

[0200] Correspondingly, the clothes hanger rod 693 can reciprocate along the vibration direction (+X, -X). Figure 7 In the enlarged cross-sectional view, the arrows indicate the direction along which the motion converter 680 reciprocates (rotates) along an arc within a predetermined range while being inserted into the slot 694. Furthermore, the range of motion of the slot 694, which vibrates along the vibration or motion direction (+X, -X), is shown by dashed lines.

[0201] Figure 8 An example in which drive 610 is connected is shown. Figure 9 (a) shows the driver 610, the support member 670 and the motion converter 680. Figure 9 (b) shows the vibrator 630.

[0202] Reference Figure 8 and Figure 9 The actuator elastic member 635 may be configured to elastically deform or recover when the actuator 610 rotates relative to the central axis Oc. The actuator elastic member 635 may also be configured to elastically deform or recover when the vibrator 630 rotates relative to the central axis Oc.

[0203] The actuator elastic member 635 can limit the vibration of the actuator 610 within a predetermined angular range. Therefore, the elastic force of the actuator elastic member 635 and the centrifugal force of the first eccentric portion 6341 and the second eccentric portion 6342 can determine the vibration mode (amplitude and frequency) of the actuator 610. This is due to the performance of second-order harmonic oscillation, which is roughly determined by the mass, spring, and damper.

[0204] The vibration mode of the driver 610 can be determined by the amplitude and frequency of the driver 610. The frequency of the driver 610 refers to the number of reciprocating motions of the driver 610, and more specifically, the number of times the driver 610 rotates from its initial position in a first rotational direction, rotates in a second rotational direction opposite to the first rotational direction, and then returns to its initial position within a predetermined time period. The unit of frequency is typically cycles per second (Hz) or revolutions per minute (RPM). The amplitude of the driver 610 can refer to a predetermined angle of rotation of the driver 610.

[0205] The vibration mode of the actuator 610 can be changed into the reciprocating motion of the hanger rod 693 by the motion converter 680, and the final vibration mode of the actuator 610 can determine the amplitude and frequency of the hanger rod 693. The amplitude of the hanger rod 693 refers to the maximum distance from the initial position when the hanger rod 693 moves along the direction of motion (+X, -X) from the initial position. The frequency of the hanger rod 693 refers to the number of times the hanger rod 693 returns to the initial position after one reciprocating motion along the direction of motion within a predetermined time. Similarly, cycles per second (Hz) or revolutions per minute (RPM) are commonly used as units of frequency. In this specification, unless otherwise stated, RPM can refer to the number of revolutions per minute of the hanger rod 693, and amplitude can also refer to the amplitude of the hanger rod 693.

[0206] Furthermore, the time required for the clothes hanger rod 693 to reciprocate once can be expressed as a period, which can be expressed as the reciprocal of the frequency.

[0207] One end of the actuator elastic member 635 can be fixed to the vibrator 630, and the other end can be fixed to the support member 670. The actuator elastic member 635 may include a spring.

[0208] As described above, the driver 620 may include: a motor 620 configured to generate torque; a vibrator 630 configured to support the motor 620 and vibrate alternately in a first and a second rotational direction opposite to each other by rotation of the motor 620; and a motion converter 680 configured to rotate with the vibrator 630 and convert the vibration of the vibrator 630 to allow the hanger rod 693 to reciprocate along a predetermined direction of motion associated with the hanger rod 693.

[0209] The vibrator 630 can be connected to the support frame 15 via a support member 670. Furthermore, the vibrator 630 can define the exterior of the driver 610. The vibrator 630 can be configured to rotate relative to the support frame 15 about a central axis Oc constructed relative to the motor rotation shaft 625.

[0210] The support member 670 may be configured to rotatably support the vibrator 630. Furthermore, the vibrator 630 may be configured to rotate within a predetermined angular range. For example, the support frame 15 or the support member 670 may include a limiter (not shown) capable of contacting the vibrator 630 to limit the rotational range of the vibrator 630. Alternatively, based on the fact that the elastic force of the actuator elastic member 635 increases as the vibrator 630 rotates further, the rotational range of the vibrator 630 may be limited without a limiter.

[0211] The vibrator 630 may further include: a first eccentric portion 6341 having an eccentric counterweight and configured to rotate relative to a first rotation axis Ow1 parallel to the motor rotation axis (or central axis Oc) associated with the motor 620; and a second eccentric portion 6342 having an eccentric counterweight and configured to rotate relative to a second rotation axis Ow2 parallel to the motor rotation axis 625 associated with the motor 620. The second rotation axis Ow2 may be positioned relative to the first rotation axis Ow1 about the motor rotation axis 625 along the width direction of the cabinet 10.

[0212] The vibrating body 630 may be configured to rotatably support the motor 620, the first eccentric portion 6341, and the second eccentric portion 6342. The first eccentric portion 6341 and the second eccentric portion 6342 may be configured to rotate by the rotation of the motor 620 and cause the vibrating body 630 to vibrate alternately in a first rotation direction and a second rotation direction that are opposite to each other.

[0213] The vibrator 630 can be configured to support the motor 620. The vibrator 630 and the motion converter 680 can be coupled so that they rotate together. The vibrator 630 can be configured to support counterweight shafts 6381 and 6382. Furthermore, the vibrator 630 can be configured to support a first eccentric portion 6341 and a second eccentric portion 6342. The vibrator 630 can be configured to accommodate the first eccentric portion 6341 and the second eccentric portion 6342 therein.

[0214] The vibrator 630 may further include: a vibrating base 6313 configured to support the motor 620, the first eccentric portion 6341 and the second eccentric portion 6342; and a vibrating housing 631 connected to the vibrating base 6313 and configured to define a space for accommodating the first eccentric portion 6341 and the second eccentric portion 6342.

[0215] The actuator 610 may include a first eccentric portion 6341 configured to rotate about a first rotational axis Ow1 spaced from the central axis Oc, causing weight eccentricity. The first eccentric portion 6341 may be configured to rotate about the first rotational axis Ow1, causing weight eccentricity. The actuator 610 may include a second eccentric portion 6342 configured to rotate about a second rotational axis Ow2 spaced from the central axis Oc, causing weight eccentricity. The second eccentric portion 6342 may be configured to rotate about the second rotational axis Ow2, causing weight eccentricity.

[0216] The first axis of rotation Ow1 and the second axis of rotation Ow2 may be the same as or different from each other. The second axis of rotation Ow2 may be the same as or parallel to the first axis of rotation Ow1. Figure 8 and Figure 9 An example is shown where the first axis of rotation Ow1 and the second axis of rotation Ow2 are parallel to each other.

[0217] Reference Figure 9 (a) and Figure 9 (b) The actuator 610 may include an elastic member engagement 636 that engages with one end of the actuator elastic member 635. When the actuator 610 rotates relative to the central axis Oc, the actuator elastic member 635 may elastically deform through the elastic member engagement 636, or the restoring force of the actuator elastic member 635 may be transmitted to the elastic member engagement 636. Therefore, the elastic member engagement 636 may be positioned on the vibrator 630.

[0218] The elastic member engagement 636 may include a first elastic member engagement 6361 that engages with one end of the first elastic member 6351. The first elastic member engagement 6361 may be formed above the connecting arm 633. The elastic member engagement 636 may also include a second elastic member engagement 6362 that engages with one end of the second elastic member 6352. The second elastic member engagement (not shown) may be formed on the underside of the vibration base 6313. The elastic member engagement 636 may include a third elastic member engagement (not shown) that engages with one end of a third elastic member (not shown). The third elastic member engagement may be formed in the motion converter 680.

[0219] A drive elastic member 635 may be disposed between the drive 610 and the support member 670. One end of the drive elastic member 635 may engage with the drive 50, while the other end may engage with the elastic member mounting portion 677 of the support member 670. The drive elastic member 635 may be a torsion spring.

[0220] The actuator elastic members 6351 and 6352 may include one or more elastic members. Each of the actuator elastic members 6351 and 6352 may be configured to elastically deform when the actuator 610 rotates in one of a first rotational direction and a second rotational direction, and elastically recover when the actuator 610 rotates in the other direction.

[0221] A first elastic member 6351 may be disposed above the driver 610. One end of the first elastic member 6351 may engage with a first elastic member engagement portion 6361, and the other end may engage with a first mounting portion 6771 of the support member 670. The first elastic member 6351 may include a torsion spring disposed around a central axis portion 675.

[0222] The second elastic member 6352 may be disposed below the actuator 610. One end of the second elastic member 6352 may engage with the second elastic member engagement portion 6362 of the actuator 610, and the other end may engage with the second mounting portion 6772 of the support member 670. The second elastic member 6352 may include a torsion spring disposed around a support base plate through hole 6711 located in the support base plate 671, facing the central shaft portion 675.

[0223] A third elastic member (not shown) may be disposed below the support base plate 671. The third elastic member may be disposed between the support base plate 671 and the motion converter 680. One end of the third elastic member may engage with the third engagement portion (not shown) of the driver 610, and the other end may engage with the third mounting portion (not shown) of the support member 670. The third elastic member may include a torsion spring disposed around the rotating protrusion 6811.

[0224] The support member 670 may include a support base plate 671 disposed below the vibrator 630. The support base plate 671 may be formed in the shape of a horizontal plate. The support base plate 671 may have a support base plate through hole 6711 formed on the central axis Oc, and a rotating protrusion 6811 may be inserted into the support base plate through hole 6711. A bearing B2 may be disposed on the support base plate through hole 6711, such that the rotating protrusion 6811 can be rotatably supported.

[0225] The support member 670 may also include a support upper plate 672 disposed above the vibrator 630 and a support extension 673 configured to connect the support upper plate 672 and the support bottom plate 671.

[0226] The upper support plate 672 can be formed in the shape of a horizontal plate. The support member 670 may include a central shaft portion 675 protruding from the upper support plate 672 along the central axis Oc. The central shaft portion 675 may protrude downward from the lower surface of the upper support plate 672. The lower end of the central shaft portion 675 may be inserted into a rotating shaft connection groove 6331 via a connecting box. The central shaft portion 675 may be configured to rotatably support the vibrator 630 via a bearing B1.

[0227] The support extension 673 can extend along the height direction of the cabinet 10 and is configured to connect the upper support plate 672 and the lower support plate 671. A pair of support extensions 673 can be provided at both ends of the upper support plate 672.

[0228] The support member 670 may include an elastic member mounting portion 677 that engages with one end of the actuator elastic member 635. A first mounting portion 6771 may be fixed to the lower surface of the upper support plate 672, and a second mounting portion 6772 may be fixed to the upper surface of the lower support plate 671. A third mounting portion (not shown) may be located on the underside of the lower support plate 671.

[0229] The motion converter 680 can be connected to the vibrator 630, allowing the motion converter 680 to rotate together with the vibrator 630. The motion converter 680 can be connected to the clothes hanger rod 693 at a predetermined distance Oh from the central axis Oc. The motion converter 680 can transmit the vibration of the vibrator 630 to the clothes hanger rod 693.

[0230] The motion converter 680 may be configured to transmit the vibration of the vibrator 630 to the hanger rod 693 along the connecting axis Oh. The motion converter 680 may include a rotating protrusion 6811 projecting along the connecting axis Oh. The rotating protrusion 6811 may project from the vibrator 630 toward the hanger rod 693 parallel to the central axis Oc. A connecting protrusion 6813 may project along the connecting axis Oh. Furthermore, the rotating protrusion 6811 and the connecting protrusion 6813 may be connected by a connecting rod 6812.

[0231] One end of the connecting protrusion 6813 can be inserted into the slot 694. Therefore, the motion converter 680 can be configured to convert the vibration of the driver 610 to cause the clothes hanger rod 693 to reciprocate along a predetermined motion or vibration direction.

[0232] Figure 10This is an exploded view of the actuator 610. As described above, the actuator 610 may include: a motor 620; a vibrator 630 configured to support the motor 620 and vibrate alternately in clockwise and counterclockwise directions by rotation of the motor 620; and a motion converter 680 configured to rotate with the vibrator 630 and convert the vibration of the vibrator 630 to allow the hanger rod 693 to reciprocate along a predetermined direction of motion associated with the hanger rod 693. The actuator 610 may also include an actuator elastic member 635 to change the amplitude and frequency of the hanger rod 693 based on harmonic excitation characteristics.

[0233] The vibrator 630 may further include: a first eccentric portion 6341 having an eccentric counterweight and configured to rotate relative to a first rotation axis Ow1 parallel to a motor rotation axis (or central axis Oc) associated with the motor 620; and a second eccentric portion 6342 having an eccentric counterweight and configured to rotate relative to a second rotation axis Ow2 parallel to a motor rotation axis 625 associated with the motor 620. The second rotation axis Ow2 may be positioned relative to the first rotation axis Ow1 with respect to the motor rotation axis 625 along the width direction of the cabinet 10.

[0234] The vibrator 630 may be configured to rotatably support the motor 620, the first eccentric portion 6341, and the second eccentric portion 6342. The first eccentric portion 6341 and the second eccentric portion 6342 may be configured to rotate by the rotation of the motor 620 and cause the vibrator 630 to vibrate alternately in the first and second rotational directions that are opposite to each other.

[0235] The first eccentric portion 6341 can be supported by the vibrating body 630. The first eccentric portion 6341 can be rotatably supported by a first counterweight shaft 6381 provided on the vibrating body 630. The second eccentric portion 6342 can be supported by the vibrating body 630. The second eccentric portion 6342 can be rotatably supported by a second counterweight shaft 6382 provided on the vibrating body 630.

[0236] The centers of mass of the first eccentric portion 6341 and the second eccentric portion 6342 have a 180-degree phase difference, and the rotation directions of the first eccentric portion 6341 and the second eccentric portion 6342 can be the same. That is, when the first eccentric portion 6341 rotates along the first rotation direction, the second eccentric portion 6342 can also rotate along the first rotation direction. When the first eccentric portion 6341 rotates along a second rotation direction opposite to the first rotation direction, the second eccentric portion 6342 can also rotate along the second rotation direction. For this purpose, the vibrating body 630 may further include: a gear-shaped central transmission unit 6453 based on the rotation of the motor 620; and gear-shaped first and second transmission units 6451 and 6452, which are disposed on both sides of the central transmission unit 6453 and configured to cause the first eccentric portion 6341 and the second eccentric portion 6342 to rotate in the same direction.

[0237] In summary, the centers of mass of the first eccentric portion 6341 and the second eccentric portion 6342 can have a phase difference of 180 degrees relative to each other, and the rotation directions of the first eccentric portion 6341 and the second eccentric portion 6342 can be the same.

[0238] Since the central transmission unit 6453, the first transmission unit 6451 and the second transmission unit 6452 are configured to engage as gears and rotate together, the rotation direction of the first transmission unit 6451 and the second transmission unit 6452 can be determined by the rotation direction of the central transmission unit 6453. That is, the first transmission unit 6451 and the second transmission unit 6452 can be configured to rotate in the same direction.

[0239] Alternatively, in the absence of the first transmission unit 6451 and the second transmission unit 6452, the central transmission unit 6453 can be directly connected to the first rotating part 6371 and the second rotating part 6372, which are in the form of gears or pulleys.

The central portion 6372a may have a hole at its center along the second axis of rotation Ow2. That is, the central portion 6372a may have a pipe shape.

[0263] The second rotating portion 6372 may include a peripheral portion 6372b mounted on the central portion 6372a. The central portion 6372a can pass through the peripheral portion 6372b. The peripheral portion 6372b may have a cylindrical shape extending along the second axis of rotation Ow2.

The centrifugal side of the counterweight mounting groove 6372c relative to the second axis of rotation Ow2 in the distal direction may be blocked. The peripheral portion 6372b and the first counterweight member 6342a may be configured to rotate together.

[0264] The motion converter 680 may include a rotating protrusion 6811 fixed to the vibrator 630. The upper end of the rotating protrusion 6811 may be fixed to the lower part of the vibrator 630. Therefore, the rotating protrusion 6811 may be configured to rotate together with the vibrator 630.

[0265] The rotating protrusion 6811 can pass through the support base plate 671 along the central axis Oc. A bearing B2 can be disposed between the rotating protrusion 6811 and the support base plate 671. Therefore, the rotating protrusion 6811 can be rotatably supported by the support base plate 671. The rotating protrusion 6811 can be configured to transmit the torque of the vibrating body 630 to the clothes hanger rod 693 via a connecting rod 6812 and a connecting protrusion 6813.

[0266] The connecting rod 6812 can be configured to rotate together with the rotating protrusion 6811. A connecting protrusion 6813 extending along the connecting axis Oh can be connected to one end of the connecting rod 6812. The connecting protrusion 6813 can be inserted into the slot 694 to convert the vibration of the vibrator 630 into the reciprocating motion of the hanger rod 693.

[0267] In this document, the direction of motion or vibration of the clothes hanger rod 693 (+X, -X) refers to the predetermined direction along which the clothes hanger rod 693 reciprocates, and in this embodiment, the vibration direction of (+X, -X) is left and right.

[0268] In this document, the central axis Oc, the first rotation axis Ow1, the second rotation axis Ow2, and the connecting axis Oh are virtual axes used to describe this disclosure and do not involve actual device components.

[0269] The center axis Oc refers to an imaginary straight line that serves as the rotation center of the drive 610. The center axis Oc is an imaginary straight line that maintains a fixed position relative to the cabinet 10. The center axis Oc can extend along the height direction of the cabinet 10.

[0270] In this embodiment, a central shaft portion 675 protruding from the support member 670 along the central axis Oc can be formed, and a support base plate through hole 6711 or a through hole rotatably engaging with the central shaft portion 675 can be formed in the vibrator 630 to provide the function of the central axis Oc. In another embodiment, a protrusion protruding along the central axis Oc can be formed in the vibrator 630, and a groove rotatably engaging the protrusion can be formed in the support member 670 to provide the function of the central axis Oc.

[0271] The first rotation axis Ow1 refers to an imaginary straight line that serves as the rotation center of the first eccentric part 6341. The first rotation axis Ow1 maintains a fixed position relative to the vibrating body 630. That is, even if the vibrating body 630 moves, the first rotation axis Ow1 moves integrally with the vibrating body 630 and maintains its relative position with respect to the vibrating body 630. The first rotation axis Ow1 can extend along the height direction of the cabinet 10.

[0272] In this embodiment, the first counterweight shaft 6381 may be disposed on the first rotation axis Ow1 to provide the function of the first rotation axis Ow1. In another embodiment, a protrusion projecting along the first rotation axis Ow1 may be formed in one of the first eccentric portion 6341 and the vibrator 630, and a groove rotatably engaging with the protrusion may be formed in the other to provide the function of the first rotation axis Ow1.

[0273] The second rotation axis Ow2 refers to an imaginary straight line that serves as the rotation center of the second eccentric part 6342. The second rotation axis Ow2 maintains a fixed position relative to the vibrator 630. That is, even if the vibrator 630 moves, the second rotation axis Ow2 moves integrally with the vibrator 630 and maintains its relative position with respect to the vibrator 630. The second rotation axis Ow2 can extend along the height direction of the cabinet 10.

[0274] In this embodiment, the second counterweight shaft 6382 may be disposed on the second rotation axis Ow2 to provide the function of the second rotation axis Ow2. In another embodiment, a protrusion projecting along the second rotation axis Ow2 may be formed in one of the second eccentric portion 6342 and the vibrator 630, and a groove rotatably engaging with the protrusion may be formed in the other to provide the function of the second rotation axis Ow2.

[0275] The connecting axis Oh is an imaginary straight line spaced apart from the central axis Oc. The connecting axis Oh is arranged parallel to the central axis Oc. The connecting axis Oh maintains a fixed position relative to the vibrating body 630. That is, even if the vibrating body 630 moves, the connecting axis Oh moves integrally with the vibrating body 630 and maintains its relative position. The connecting axis Oh can extend vertically. The motion converter 680 can be positioned along the connecting axis Oh at the connection point between the driver 610 and the hanger rod 693, such that the alternating rotation (vibration) of the driver 610 is converted into the linear reciprocating motion of the hanger rod 693.

[0276] The circumferential direction Dl refers to the circumferential direction centered on the central axis Oc, and includes a first rotational direction D11 and a second rotational direction D12 opposite to the first rotational direction D11. The first rotational direction D11 and the second rotational direction D12 are defined based on the state observed from one of the directions (+Z) of the extension direction (+Z, -Z) of the central axis Oc.

[0277] When the direction of the centrifugal force F1 around the first rotation axis Ow1 caused by the rotation of the first eccentric part 6341 is equal to the circumferential direction Dl, the centrifugal force F1 can cause the vibrating body 630 to rotate relative to the central axis Oc. Furthermore, when the direction of the centrifugal force F2 around the second rotation axis Ow2 caused by the rotation of the second eccentric part 6342 is equal to the circumferential direction Dl, the centrifugal force F2 can cause the vibrating body 630 to rotate relative to the central axis Oc.

[0278] The diameter direction Dr refers to the direction transverse to the central axis Oc, and includes the centrifugal direction Dr1 and the centripetal direction Dr2. The centrifugal direction Dr1 means the direction away from the central axis Oc, while the centripetal direction Dr2 means the direction closer to the central axis Oc.

[0279] When the direction of the centrifugal force F1 around the first rotation axis Ow1 caused by the rotation of the first eccentric part 6341 is equal to the diameter direction Dr, the centrifugal force F1 will not cause the vibrating body 630 to rotate relative to the central axis Oc. When the direction of the centrifugal force F2 around the second rotation axis Ow2 caused by the rotation of the second eccentric part 6342 is equal to the diameter direction Dr, the centrifugal force F2 will not cause the vibrating body 630 to rotate relative to the central axis Oc.

[0280] Figures 11 to 14 This is a simplified diagram of the driver 610 to illustrate the harmonic excitation motion of the driver 610.

[0281] Figures 11 to 14The diagram shows the center of mass m1 of the first eccentric part 6341, the center of mass m2 of the second eccentric part 6342, the radius of rotation r1 of the center of mass m1 relative to the first rotation axis Ow1, the radius of rotation r2 of the center of mass m2 relative to the second rotation axis Ow2, the angular velocity w of the first eccentric part 6341 relative to the first rotation axis Ow1, the angular velocity w of the second eccentric part 6342 relative to the second rotation axis Ow2, the distance A1 between the central axis Oc and the first rotation axis Ow1, the distance A2 between the central axis Oc and the second rotation axis Ow2, and the distance B between the central axis Oc and the connecting axis Oh.

[0282] Figures 11 to 14 The directions of the centrifugal force F1 of the first eccentric part 6341 around the first rotation axis Ow1 and the centrifugal force F2 of the second eccentric part 6342 around the second rotation axis Ow2 are shown. The sum of the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 can be the torque of the vibrating body 630. By taking into account the torque arm lengths A1, A2 and B of the sum of the centrifugal forces F1 and F2, the excitation force Fo can be expressed as an external force having a point of application on the connecting axis Oh.

[0283] The magnitude of centrifugal force F1 is m1·r1·w2, and the magnitude of centrifugal force F2 is m2·r2·w2. The centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 are applied to the vibrating body 630. The points of application of the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 can be points on the first rotation axis Ow1 and the second rotation axis Ow2, respectively. Since the first eccentric part 6341 and the second eccentric part 6342 rotate at the same speed through the rotation transmission unit 645, they can also rotate at the same angular velocity w.

[0284] Reference Figure 11 When the torque of the vibrating body 630 is generated around the central axis Oc, the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 can reinforce each other. That is, when the weight of the first eccentric part 6341 deviates from the center of the first rotation axis Ow1 relative to the central axis Oc along one of the directions D11 and D12, the weight of the second eccentric part 6342 can deviate from the center of the second rotation axis Ow2 along the direction D1.

[0285] When the first eccentric part 6341 generates a centrifugal force about the first rotation axis Ow1 in one direction D1 relative to the central axis Oc along the first rotation direction D11 and the second rotation direction D12, the second eccentric part 6342 can generate a centrifugal force about the second rotation axis Ow2 in the direction D1. In this case, the torque A1·F1+A2·F2 caused by the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 is the same as the torque B·Fo caused by the excitation force Fo. Therefore, the excitation force Fo can be (A1·F1+A2·F2) / B. Therefore, in Figure 11 In the example, the vibrator 630 can rotate clockwise, causing the motion converter 680 to also rotate clockwise.

[0286] Reference Figure 12 The centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 point in opposite directions relative to the central axis Oc of the vibrating body 630. In this case, since the resultant force becomes 0, no torque is generated. When the weight of the first eccentric part 6341 deviates from the center of the first rotation axis Ow1 relative to the central axis Oc along one direction D2 of the centrifugal direction Dr1 and the centripetal direction Dr2, the weight of the second eccentric part 6342 can deviate from the center of the second rotation axis Ow2 in the opposite direction to direction D2.

[0287] In this case, since centrifugal forces F1 and F2 act in opposite directions, the sum of centrifugal forces F1 and F2 is equal to the difference between the magnitudes of centrifugal forces F1 and F2. Therefore, at least one of centrifugal forces F1 and F2 can be canceled out by the other.

[0288] Therefore, the actuator 610 moves the hanger rod 693 by rotating it. In this case, the centrifugal force F1 of the first eccentric part 6341 that rotates the actuator 610 and the centrifugal force F2 of the second eccentric part 6342 can reinforce each other in the circumferential direction Dl, thereby generating vibration along the predetermined vibration direction (+X, -X). However, the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 that do not rotate the actuator 610 can be offset from each other in the diametrical direction Dr, thereby preventing the hanger rod 3 from vibrating in a direction (+Y, -Y) orthogonal to the vibration direction (+X, -X).

[0289] Preferably, when no torque is applied to the vibrator 630, the centrifugal forces F1 of the first eccentric portion 6341 and F2 of the second eccentric portion 6342 can completely cancel each other out. Here, "completely cancel out" means that the sum of the centrifugal forces F1 of the first eccentric portion 6341 and F2 of the second eccentric portion 6342 is zero. This can minimize unwanted vibrations generated along directions perpendicular to the predetermined vibration direction (+X, -X) (+Y, -Y).

[0290] In order to make the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 completely cancel each other out along the diameter direction Dr, the scalar m1·r1 and the scalar m2·r2 can be set to be equal to each other.

[0291] The radius of rotation R1 of the center of mass m1 of the first eccentric part 6341 relative to the first axis of rotation Ow1 and the radius of rotation R2 of the center of mass m2 of the second eccentric part 6342 relative to the second axis of rotation Ow2 can be set to be equal (r1 = r2). The mass m1 of the first eccentric part 6341 and the mass m2 of the second eccentric part 6342 can be set to be equal (m1 = m2). Based on these two conditions (r1 = r2 and m1 = m2), the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 can completely cancel each other out along the diametrical direction Dr. Even when the radii of rotation r1 and r2 are different and the masses m1 and m2 are different, if the scalars m1·r1 and m2·r2 are set to be equal to each other, the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 can completely cancel each other out along the diametrical direction Dr.

[0292] The distance A1 between the first rotation axis Ow1 and the central axis Oc, and the distance A2 between the second rotation axis Ow2 and the central axis Oc, can be the same. In this case, the centrifugal forces F1 and F2 help to generate the excitation force Fo in the same proportion, thereby preventing fatigue loads from concentrating in the area supporting the first eccentric part 6341 or the area supporting the second eccentric part 6342.

[0293] The first axis of rotation Ow1 and the second axis of rotation Ow2 can be spaced apart from the central axis Oc in the same or opposite directions. The central axis Oc, the first axis of rotation Ow1, and the second axis of rotation Ow2 can be configured to intersect perpendicularly to a virtual straight line. Figures 4 to 10 In the embodiment shown, the first rotation axis Ow1 and the second rotation axis Ow2 are spaced apart from the central axis Oc in opposite directions.

[0294] Therefore, the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 can cancel each other out along the diameter direction Dr.

[0295] The angular velocity w of the first eccentric part 6341 about the first rotation axis Ow1 and the angular velocity w of the second eccentric part 6342 about the second rotation axis Ow2 can be set to be equal to each other. This allows the centrifugal forces F1 and F2 caused by the rotation of the first and second eccentric parts 6341 and 6342 to be periodically strengthened and counteracted.

[0296] Here, angular velocity refers to a scalar quantity that has only magnitude and no direction of rotation, which is different from angular velocity, i.e., a vector that has both direction of rotation and magnitude. That is, if the angular velocity w of the first eccentric part 6341 is equal to the angular velocity w of the second eccentric part 6342, this does not mean that they rotate in the same direction.

[0297] Reference Figures 11 to 14 The rotation direction of the first eccentric part 6341 around the first rotation axis Ow1 and the rotation direction of the second eccentric part 6342 around the second rotation axis Ow2 can be the same. The motion converter 680 can be fixed to the vibrator 630 and rotate together with the vibrator 630.

[0298] The first rotation axis Ow1 and the second rotation axis Ow2 are spaced apart from each other in opposite directions relative to the central axis Oc. Furthermore, the first rotation axis Ow1 and the second rotation axis Ow2 can be arranged symmetrically relative to the central axis Oc. This prevents the vibrating body 630 from being biased to one side relative to the central axis Oc due to the weights m1 and m2 of the first and second eccentric portions 6341 and 6342.

[0299] Reference Figures 11 to 14 When the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 cancel each other out, both the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 can act in the centrifugal direction Dr1 or the centripetal direction Dr2.

[0300] Figures 11 to 14 The diagram shows the state in which the first eccentric part 6341 and the second eccentric part 6342 rotate 90 degrees at the same angular velocity w.

[0301] Reference Figure 11 When the first eccentric portion 6341 generates a centrifugal force F1 relative to the first rotation axis Ow1 along the first rotation direction D11, the second eccentric portion 6342 generates a centrifugal force F2 relative to the second rotation axis Ow2 along the first rotation direction D11. Therefore, the centrifugal forces F1 of the first eccentric portion 6341 and F2 of the second eccentric portion 6342 reinforce each other, thereby generating a torque for the vibrating body 630 along the first rotation direction D11. The excitation force Fo transmitted to the hanger rod 693 on the connecting axis Oh can act along the first rotation direction D11.

[0302] Reference Figure 12When the first eccentric part 6341 generates a centrifugal force F1 relative to the first rotation axis Ow1 in the centripetal direction Dr2, the second eccentric part 6342 generates a centrifugal force F2 relative to the second rotation axis Ow2 in the centripetal direction Dr2. Therefore, the centrifugal forces F1 of the first eccentric part 6341 and F2 of the second eccentric part 6342 do not generate torque for the vibrating body 630. The excitation force Fo transmitted to the hanger rod 693 on the connecting axis Oh becomes zero. The centrifugal forces F1 of the first eccentric part 6341 and F2 of the second eccentric part 6342 can act in opposite directions and thus cancel each other out.

[0303] Reference Figure 13 When the first eccentric portion 6341 generates a centrifugal force F1 relative to the first rotation axis Ow1 along the second rotation direction Dl2, the second eccentric portion 6342 generates a centrifugal force F2 relative to the second rotation axis Ow2 along the second rotation direction Dl2. Therefore, the centrifugal forces F1 of the first eccentric portion 6341 and F2 of the second eccentric portion 6342 reinforce each other, thereby generating a torque for the vibrating body 630 along the second rotation direction Dl2. The excitation force Fo transmitted to the hanger rod 693 on the connecting axis Oh can act along the second rotation direction Dl2.

[0304] Reference Figure 14 When the first eccentric part 6341 generates a centrifugal force F1 relative to the first rotation axis Ow1 along the centrifugal direction Dr1, the second eccentric part 6342 generates a centrifugal force F2 relative to the second rotation axis Ow2 along the centripetal direction Dr2. Therefore, the centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 do not generate torque for the vibrating body 630. The excitation force Fo transmitted to the hanger rod 693 on the connecting axis Oh becomes zero. The centrifugal force F1 of the first eccentric part 6341 and the centrifugal force F2 of the second eccentric part 6342 can act in opposite directions and thus cancel each other out.

[0305] Therefore, refer to Figures 11 to 14 When the motor 620 rotates clockwise or counterclockwise, the vibrator 630 can rotate alternately in opposite first and second rotation directions depending on where the weight of the first eccentric part 6341 and the second eccentric part 6342 is concentrated.

[0306] The alternating rotation of the vibrator 630 can cause the motion converter 680 to reciprocate along an arc, and the reciprocating motion of the motion converter 680 can be converted by the groove 694 into the reciprocating motion of the clothes hanger rod 693 along a predetermined motion or vibration direction.

[0307] Figure 15(a) shows a graph of the amplitude and frequency of the hanger rod 693, which can be obtained through physical analysis of the harmonic excitation motion of the actuator 610. Since the reciprocating motion of the actuator 610 is ultimately converted into the reciprocating motion of the hanger rod 693, this graph can be considered as a graph of the frequency and amplitude of the hanger rod 693.

[0308] If the weight m1 of the first eccentric part 6341 and the weight m2 of the second eccentric part 6342 are at any position, the harmonic excitation motion of the driver 610 can be represented by the second-order differential equation shown in Equation 1 below.

[0309] [Equation 1]

[0310]

[0311] In Equation 1, p1, p2, and p3 are non-zero constants. Specifically, p1 is the mass of the garment support 600 excluding the support member 670 fixed to the support frame 15; the damping coefficient p2 can be generated by the structural factors of the garment support 600 and / or the garments suspended on the hanger rod 693; the elastic modulus p3 is generated by the actuator elastic member 635; and x is the position of the connecting axis Oh along the direction of motion (+X, -X) depending on time t. If the first eccentric part 6341 and the second eccentric part 6342 have the same weight and the same distance from the central axis, the excitation force Fo can be calculated by m·r·w. 2 Let w be the angular velocity, m be the mass of each eccentric part, and r be the distance of each eccentric part from the central axis.

[0312] When solving Equation 1, the natural frequency (resonant frequency) of the driver can be expressed by Equation 2 below.

[0313] [Equation 2]

[0314]

[0315] In equation 2, ω n It represents the natural frequency (resonant frequency).

[0316] If Equation 3 below is satisfied, the driver can have maximum amplitude near its natural frequency. If Equation 3 is not satisfied, the amplitude monotonically decreases with increasing frequency. As a result, the amplitude may not change with frequency, which is not preferable.

[0317] [Equation 3]

[0318] p1·p3≥p2 2

[0319] In Equation 3, the larger the value of p2, the larger the amplitude can be (where p2 is a positive integer).

[0320] like Figure 15 As shown in (a), based on equations 1 to 3, a graph can be obtained by representing the amplitude of the hanger rod 693 (using arbitrary units (AU) since only relative dimensions are involved) according to the frequency (or revolutions per minute (RPM)) of the hanger rod 693.

[0321] Various modes of the clothes hanger rod 693 can be set from the curve based on the frequency and amplitude. Here, a mode means that the clothes hanger rod 693 reciprocates along a predetermined motion or vibration direction at a predetermined frequency and amplitude.

[0322] If the curve is... Figure 15 If the curve of (a) is different from the curve of (a) and is monotonically decreasing, then the amplitude may not change with frequency. Therefore, as Figure 15 The example shown in (a) may make it difficult to distinguish different patterns in the four regions. Therefore, in order to obtain Figure 15 The curve shown in (a) needs to satisfy the conditions of Equation 3.

[0323] exist Figure 15 In (a), the four different modes are four configurable regions, which can be represented by A, B, C, and D respectively. B can be set close to the natural frequency (resonant frequency). Therefore, the hanger rod 693 can have the maximum amplitude in region B. If the hanger rod 693 reciprocates with the frequency and amplitude set in region B, it can be said that the hanger rod 693 reciprocates in mode B.

[0324] If the hanger rod 693 reciprocates with a frequency and amplitude selected in region A, it can be said that the hanger rod 693 reciprocates in mode A. Similarly, when the hanger rod 693 reciprocates with a frequency and amplitude selected in region C, it can be said that the hanger rod 693 reciprocates in mode C. Furthermore, when the hanger rod 693 reciprocates with a frequency and amplitude selected in region D, it can be said that the hanger rod 693 reciprocates in mode D.

[0325] The frequency and amplitude of the clothes hanger rod 693 can be independent of each other. However, according to this disclosure, the amplitude of the clothes hanger rod 693 can be determined based on the frequency of the clothes hanger rod 693 generated by the harmonic excitation motion. This is because the rotation angle of the driver 610 along the first and second rotation directions changes according to the frequency of the driver 610 generated by the harmonic excitation motion.

[0326] In the garment handling apparatus according to this disclosure, when the hanger rod 693 reciprocates, the amplitude of the hanger rod 693 can be changed according to the period of the hanger rod 693 or the frequency of the hanger rod 693 related to the period of the hanger rod 693. That is, the amplitude of the hanger rod 693 can be determined by the frequency of the hanger rod 693.

[0327] Figure 15 Figures (b) through (e) show the amplitude variation over time when the clothes hanger rod 693 is running in modes A, B, C, and D, respectively. Due to the harmonic excitation characteristics, the amplitude has a sinusoidal shape.

[0328] The frequency and amplitude of the hanger rod 693 can be defined as follows: The frequency of the hanger rod 693 is the reciprocal of the time it takes for the hanger rod 693 to move left and right once from its initial position and then return to its initial position. In other words, the frequency of the hanger rod 693 is the reciprocal of the time it takes for the hanger rod 693 to return to its initial position after one reciprocating motion (cycle). In this document, revolutions per minute (RPM) is used as the unit to express the frequency of the hanger rod 693, rather than in Hz.

[0329] The amplitude of hanger rod 693 refers to the maximum distance the hanger rod can move to the left and right from its initial position. The initial position refers to the position of hanger rod 693 when it stops. Since the magnitude of the amplitude is not an absolute value but can change due to the mass of the actuator 610, the amplitude is expressed as a unitless (or relative value based on arbitrary units (AU)) value.

[0330] Reference Figure 15 From (a) to (e) of 15, the frequency in mode A can be less than the resonant frequency of driver 610, and the frequency in mode C can be set to be greater than the resonant frequency.

[0331] The frequency and amplitude in mode A can also be referred to as the first frequency and the first amplitude, and mode A can be referred to as the first mode. Similarly, the frequency and amplitude in mode C can also be referred to as the second frequency and the second amplitude, and mode C can be referred to as the second mode.

[0332] The first frequency can be set to a frequency lower than the resonant frequency of the driver 610, while the second frequency can be set to a frequency higher than the resonant frequency of the driver 610. The clothes hanger rod 693 can operate in one of the first and second modes. In the first mode, the clothes hanger rod 693 can reciprocate at a predetermined first frequency lower than the resonant frequency of the driver 610 and with a first amplitude based on the first frequency. In the second mode, the clothes hanger rod 693 can reciprocate at a predetermined second frequency higher than the resonant frequency, and the second amplitude depends on the second frequency.

[0333] Reference Figure 15 In (a), the first frequency may be less than the second frequency. However, the first amplitude may be similar to the second amplitude, or the first amplitude may be slightly larger than the second amplitude.

[0334] The frequency and amplitude in mode B can also be referred to as the third frequency and third amplitude, and mode B can be called the third mode. Similarly, the frequency and amplitude in mode D can also be referred to as the fourth frequency and fourth amplitude, and mode D can be called the fourth mode.

[0335] The third frequency can be similar to the resonant frequency at which resonance can occur. Since undesirable vibrations or tremors may occur at the resonant frequency, the third frequency can be preset to any frequency near the resonant frequency to avoid such undesirable vibrations or tremors. The clothes hanger rod 693 can operate in any of the first, second, and third modes. In the third mode, the clothes hanger rod 693 can reciprocate at a third frequency between the first and second frequencies, and the third amplitude depends on the third frequency. Furthermore, the third amplitude can be greater than the first and second amplitudes.

[0336] The fourth frequency can be set to be greater than the second frequency. The clothes hanger rod 693 can reciprocate in any of the first, second, third, and fourth modes. In the fourth mode, the clothes hanger rod 693 can reciprocate at a fourth frequency greater than the third frequency, and the fourth amplitude depends on the fourth frequency. The fourth amplitude can be smaller than the first, second, and third amplitudes.

[0337] To obtain the amplitude that changes significantly with frequency as described above, a harmonic excitation motion mode with a maximum value at the resonant frequency is required, such as... Figure 15 As shown in (a).

[0338] The frequency and amplitude of the driver can be set independently of each other. Therefore, the rotation angle of the driver can be set as follows: Figure 3 The variations shown allow the amplitude and frequency to change independently of each other. However, considering that the purpose of the garment handling device 1000 is garment management, it is only necessary to implement the amplitude and frequency required to perform the various functions needed for garment management, such as dust removal, drying, and wrinkle removal. In other words, it is not necessary to implement the driver in a way that allows the driver to independently change the amplitude and frequency.

[0339] Table 1 below schematically illustrates the relationship between various functions required for garment management and amplitude and frequency. In other words, Table 1 shows how dust removal, drying, and wrinkle removal functions relate to amplitude and frequency. Table 1 shows that the higher the value for each function, the better its performance.

[0340] [Table 1]

[0341]

[0342] Referring to Table 1, increasing the frequency (RPM) of the hanger rod 693 improves the dust removal function. Conversely, decreasing the frequency (RPM) of the hanger rod 693 improves the drying function. Increasing the amplitude improves the wrinkle removal function. When the frequency and amplitude of the hanger rod 693 decrease, the performance of the dust removal and drying functions may decrease. Therefore, except in special cases, modes with small amplitudes or frequencies may not be used.

[0343] Specifically, increasing the frequency (RPM) of the hanger rod 693 can improve dust removal performance. This is because the faster the hanger rod 693 reciprocates, the more dust can be removed from the clothes due to inertia. However, even with a high frequency, a small amplitude may not be suitable for dust removal. That is, if the amplitude is small, the inertia may be insufficient to dislodge the dust.

[0344] As described above, the drying function can be improved by reducing the frequency (RPM) of the hanger rod 693. However, since the garment handling apparatus 1000 according to this disclosure uses drying via a heat pump instead of dehydration via centrifugal force, hot and dry air needs to flow into the garments suspended on the garment support 600. Therefore, if the frequency (RPM) of the hanger rod 693 is high, it may obstruct airflow. However, if the amplitude is too low, it may not promote airflow, as it may be the same as a simple standing garment.

[0345] The greater the amplitude of the hanger rod 693, the better it is at removing wrinkles. This is because a larger amplitude of the hanger rod 693 is more effective at straightening the clothing, which is effective in removing wrinkles. When the clothing forms a waveform due to the amplitude of the hanger rod 693, nodes may be formed due to standing waves. Since the nodes do not change in a specific pattern, wrinkles cannot be removed from the parts of the clothing corresponding to the nodes. Therefore, the nodes must be changed, and for this purpose, it may be desirable to change the pattern of the hanger rod 693 while performing the wrinkle removal function.

[0346] Refer to Table 1 and Figure 15 As can be seen from (a), among the various modes achievable in driver 610, which mode is dedicated to which clothing management function. This is in Figure 16 As shown in the image.

[0347] Figure 16 Modes A (first mode), C (second mode), and B (third mode) achievable in the garment handling apparatus according to this disclosure, taking into account each relative frequency and amplitude, are shown. These modes are represented by A, B, and C, respectively. Mode D (fourth mode) is represented separately, considering its use in special cases.

[0348] and Figure 15In comparison, it can be seen that Mode A (first mode) is specifically designed for drying clothes. That is, when the hanger rod 693 reciprocates at a first frequency, the clothes mounted on the hanger rod 693 can be appropriately agitated. In particular, considering that steam is supplied to the clothes via the steam engine 250 and thus the weight of the wet clothes increases, when agitated at a frequency higher than the first frequency, the clothes may be shaken by the hanger H1 (see...). Figure 1 ) and clothing T (see Figure 1 Friction damage between the two. Therefore, since mode A has the lowest frequency among the various modes mentioned above, mode A is preferred. Furthermore, mode A allows for managing clothing late at night or early in the morning due to the low noise generated by the low frequency.

[0349] Mode B (the third mode) is specifically designed for wrinkle removal. Compared to other modes, the hanger rod 693 exhibits the largest amplitude in Mode B. Therefore, Mode B is suitable for removing wrinkles from clothing because the garment is shaken to the maximum extent.

[0350] Mode C (Second Mode) is specifically designed for dust removal. This is because the amplitude of Mode C is similar to that of Mode A, but the frequency of Mode C is higher than that of Mode A. Therefore, while Mode A is specifically designed for drying due to its relatively low frequency, Mode C is more effective for dust removal due to its relatively high frequency. Furthermore, although the second amplitude of Mode C is smaller than the third amplitude of Mode B, Mode C can cause the hanger rod 693 to reciprocate at a specific amplitude with a second frequency greater than the third frequency. Therefore, Mode C is even more effective than Mode A in removing wrinkles.

[0351] In other words, Mode C is not only effective for dust removal but also for wrinkle reduction. Furthermore, Mode C can restore the volume of clothing, such as padded jackets filled with stuffing. Specifically, Mode C restores the volume of clothing by tapping the stuffing material to increase the gaps between the materials. That is, Mode C has the effect of increasing the volume of clothing.

[0352] Here, dust refers to small foreign objects floating in the air and adhering to clothing. Dust can include lint, dead skin, animal hair, dirt, etc. Typically, dust has a size of 10 μm or larger. Dust with a smaller size is referred to as fine dust.

[0353] Mode D (Mode 4), with its minimum amplitude and highest frequency, can be used for specific purposes. Specifically, Mode D allows steam to penetrate well into the fabric of the garment during or after steam is injected by the steam generator 250 by transmitting fine vibrations with a high frequency and small amplitude. This is because the moisture content of the garment increases with the amount of steam penetrating it. Furthermore, increased moisture content improves wrinkle removal and deodorization. Mode D can effectively restore the hair in fur garments. This is because, due to the small size of each hair, a high frequency is required to transmit vibrations to each hair and agitate it, thus activating the hair.

[0354] In addition, due to its high frequency, mode D can effectively remove fine dust particles smaller than foreign objects or dust. This is similar to using ultrasound to remove fine dust particles using a sonicator.

[0355] The functions of Mode A (first mode), Mode B (third mode), Mode C (second mode), and Mode D (fourth mode) are summarized in Table 2 below.

[0356] [Table 2]

[0357]

[0358] Figure 17 The diagram schematically illustrates the vibration waveforms of clothing based on the four modes described above. The first and second amplitudes, i.e., modes A and C, are similar in magnitude. The fourth amplitude, i.e., mode D, has the smallest amplitude. The third amplitude, i.e., mode B, has the largest amplitude.

[0359] Figure 17 A portion of the hanger H1 holding the garment on the hanger rod 693 is shown in each mode. The double arrows indicate the direction of movement of the hanger rod 693. As the hanger rod 693 reciprocates at a predetermined amplitude and frequency in each mode, the attached garment can also generate a wave. That is, when one end of the garment T is held and shaken, a wave travels along the garment. In this case, the other end of the garment is the free end, and the wave reflects from the free end. Therefore, a standing wave can be created, thereby forming a node. (Refer to...) Figure 18 (d) can form multiple nodes in clothing depending on the size of the wave, i.e., the wavelength.

[0360] Since there is no amplitude change at the knots of clothing, knots may be undesirable for wrinkle removal and dust removal. Therefore, knots need to be modified, and for this purpose, a combination of several modes is preferably used instead of just one mode when performing wrinkle removal, dust removal, and drying functions.

[0361] Figure 18 and Figure 19Examples of performing various clothing management functions by combining the above patterns are shown. Figure 18 and Figure 19 In this process, a combination of various modes is used, which is referred to as motion. That is, motion refers to the repeated execution of a combination of at least one of several modes to perform the garment management function within a predetermined motion time. During the motion time, each mode can be repeated every predetermined time period. For example, if the first mode is executed for 30 seconds and then the second mode is executed for 5 minutes, the hanger rod 693 can alternately run in the first mode (reciprocating motion) for 30 seconds and in the second mode (reciprocating motion) for 5 minutes within one hour; this is the total wrinkle removal time.

[0362] The first and second modes can be executed continuously or discontinuously with pause durations.

[0363] A single-mode movement can continue for a duration of motion. On the other hand, various modes can be repeated during the motion period; this is called multi-mode movement. In multi-mode movement, each mode can be repeatedly executed for each predetermined time interval during the motion period.

[0364] A process can refer to a combination of actions performed within a predetermined time period.

[0365] Therefore, the process time can be set to be longer than the movement time. The movement time can be set to be longer than the time required for each of the one or more modes needed to perform the clothing management function.

[0366] Reference Figure 18 and Figure 19 When the clothes hanger rod 693 reciprocates, a third mode (mode B) needs to be included during the reciprocating motion. This is because the third mode (mode B) is the most basic mode used to achieve the motion.

[0367] Figure 18 (a) to Figure 18 (c) illustrates different types of wrinkle-removing movements for removing wrinkles from clothing in the first chamber 100.

[0368] Reference Figure 18 (a) to Figure 18 (c) The three different types of wrinkle removal movements may include at least a mode B (third mode) specifically designed for wrinkle removal to remove creases. That is, in order to remove creases from the garment in the first chamber 100, the hanger rod 693 may reciprocate in the third mode for at least a portion of the predetermined total wrinkle removal time.

[0369] Here, total wrinkle removal time refers to the total time required to perform the wrinkle removal procedure.

[0370] The third mode can be performed during the total wrinkle removal time (single-mode motion). Alternatively, the third mode can be performed only during a portion of the total wrinkle removal time. Figure 18 (a) to Figure 18 (c) illustrates a different embodiment of performing the third mode only for a portion of the wrinkle removal time.

[0371] Figure 18 (a) illustrates one embodiment of the wrinkle-removing motion. The hanger rod 693 can reciprocate in a first mode during a predetermined first wrinkle-removing time TW1. After the first wrinkle-removing time TW1 expires, the hanger rod 693 can reciprocate in a third mode during a predetermined second wrinkle-removing time TW2. During the total wrinkle-removing time, the hanger rod 693 can alternately reciprocate in the first mode during the first wrinkle-removing time TW1 and in the third mode during the second wrinkle-removing time TW2. Figure 18 (a) shows the pattern diagrams (patterns) of the first and third patterns that will be repeated continuously during the total wrinkle removal time. Figure 18 and Figure 19 Patterns of repeating patterns are shown unless otherwise stated.

[0372] Figure 18 (b) illustrates another embodiment of the wrinkle-removing motion. The hanger rod 693 can reciprocate in a third mode within a predetermined first wrinkle-removing time TW1'. After the first wrinkle-removing time TW1' expires, the hanger rod 693 can reciprocate in a second mode within a predetermined second wrinkle-removing time TW2'. During the total wrinkle-removing time, the hanger rod 693 alternately reciprocates in the third mode within the first wrinkle-removing time TW1' and in the second mode within the second wrinkle-removing time TW2'.

[0373] Figure 18 (c) illustrates another embodiment of the wrinkle-removing motion. The hanger rod 693 can reciprocate in a second mode within a predetermined first wrinkle-removing time TW1". After the first wrinkle-removing time TW1" expires, the hanger rod 693 can reciprocate in a fourth mode within a predetermined second wrinkle-removing time TW2". After the second wrinkle-removing time TW2" expires, the hanger rod 693 can reciprocate in a third mode within a predetermined third wrinkle-removing time TW3". During the total wrinkle-removing time, the hanger rod 693 can alternately reciprocate in the second mode within the first wrinkle-removing time TW1", in the fourth mode within the second wrinkle-removing time TW2", and in the third mode within the third wrinkle-removing time TW3".

[0374] As another embodiment of the wrinkle-removing motion, the hanger rod 693 operates only once during the total wrinkle-removing time in each mode, instead of repeating the second, fourth, and third modes. That is, the total wrinkle-removing time can be divided into three parts, such that the sum of the first wrinkle-removing time TW1, the second wrinkle-removing time TW2, and the third wrinkle-removing time TW3 becomes the total wrinkle-removing time. Each of the second, fourth, and third modes can be executed once.

[0375] In this case, each of the second, fourth, and third modes can be executed once, and the sum of the first wrinkle removal time TW1, the second wrinkle removal time TW2, and the third wrinkle removal time TW3 can be the total wrinkle removal time.

[0376] exist Figure 18 The wrinkle removal movement shown in (a) Figure 18 The wrinkle removal movement shown in (b) and in Figure 18 The wrinkle removal movements shown in (c) can be referred to as the first wrinkle removal movement, the second wrinkle removal movement, and the third wrinkle removal movement, respectively.

[0377] The first wrinkle-removing motion can be used to remove wrinkles from thin garments such as shirts. The first wrinkle-removing motion basically uses the third mode, namely mode B.

[0378] The first wrinkle-removing motion alternates between Mode B and Mode A. When the garment is thin and light, applying a strong mode may cause wrinkles. Therefore, the hanger rod 693 can reciprocate in Mode B by default, and can also reciprocate in Mode A in addition to Mode B. When these two modes are applied together, the position of the nodes on the garment can be changed, thereby removing wrinkles from the garment evenly.

[0379] The second wrinkle-removing motion can be used for thick and heavy clothing, such as suits or school uniforms. To remove wrinkles from thick and heavy clothing, mode B alone is insufficient, and a combination of modes B and C can be used. Similarly, when these two modes are applied together, the position of the nodes on the clothing can be changed, thus removing wrinkles evenly from the clothing.

[0380] The third wrinkle-removing motion can be used to remove wrinkles from clothing thicker than a suit. For this purpose, modes B, C, and D can be combined to maximize wrinkle-removing performance.

[0381] One of the first, second, and third wrinkle-removing movements can be selectively used based on the material and thickness of the garment. That is, the user can select the movement based on the material and thickness of the garment. For example, an input / output unit 950 configured to receive user selections and output the current operating state of the garment handling device 1000 can be disposed on the opposite surface of the inner surface 401 of the door, i.e., on the front surface (not shown) of the door 400 facing forward when the entrance 11 is closed by the door 400. When the user places garments in the first chamber 100, closes the door 400, and selects a desired menu based on the thickness, type, or material of the garment via the input / output unit 950, the controller 270 can be configured to reciprocate the hanger rod 693 based on one of the first, second, and third wrinkle-removing movements.

[0382] Figure 18 (c) can be used to explain another motion. For another motion, combinations of the second, fourth, and third modes can be repeated, but the execution time for each mode can be set differently. For example, although Figure 18 (c) together shows the predetermined first wrinkle removal time TW1", the predetermined first dust removal time TM1 and the predetermined first volume time TV1, but this indicates that the order of the modes is the same, but does not mean that the times are the same. The first wrinkle removal time TW1", the first dust removal time TM1 and the first volume time TV1 can be set differently based on each movement.

[0383] To remove fine dust and dust including foreign matter attached to clothing, the clothes need to be shaken, which may require the reciprocating motion of the hanger rod 693.

[0384] After using mode two (mode C) to remove large dust particles, mode four (mode D) can be used to remove fine dust particles attached to clothing. Due to its small amplitude and high frequency, mode four has the highest acceleration. Mode three (mode B) can be used to remove easily detached foreign objects.

[0385] For the dust removal motion, that is, in order to remove dust adhering to the clothes in the first chamber 100, the clothes hanger rod 693 can reciprocate in a second mode during at least a portion of the predetermined total dust removal time.

[0386] Here, total dust removal time refers to the total time required to perform the dust removal operation.

[0387] Essentially, the third mode can be included in all movements. The hanger rod 693 can reciprocate in the second mode during a predetermined first dust removal time TM1. Subsequently, after the first dust removal time TM1 expires, the hanger rod 693 can reciprocate in the fourth mode during a predetermined second dust removal time TM2. After the second dust removal time TM2 expires, the hanger rod 693 can reciprocate in the third mode during a predetermined third dust removal time TM3. During the predetermined total dust removal time, the hanger rod 693 can repeatedly reciprocate in the second mode during the first dust removal time TM1, repeatedly reciprocate in the fourth mode during the second dust removal time TM2, and repeatedly reciprocate in the third mode during the third dust removal time TM3.

[0388] As another embodiment of the dust removal process, the clothes hanger rod 693 can execute each mode only once, instead of repeating the second, fourth, and third modes. That is, the total dust removal time can be divided into three parts, where the total dust removal time is the sum of the first dust removal time TM1, the second dust removal time TM2, and the third dust removal time TM3. Each of the second, fourth, and third modes can be executed once.

[0389] In this case, each of the second, fourth and third modes can be executed once, and the sum of the first dust removal time TM1, the second dust removal time TM2 and the third dust removal time TM3 can be the total dust removal time.

[0390] The garment handling apparatus 1000 may further include a dust sensor unit 911 located in the first chamber 100 and configured to detect the concentration of dust in the first chamber 100. The first dust removal time may be varied based on the dust concentration detected by the dust sensor 911.

[0391] The dust sensor 911 may be configured to transmit a control signal obtained by measuring the concentration of dust or fine dust to the controller 270, and the controller 270 may be configured to determine the current concentration of dust or fine dust based on the control signal.

[0392] The controller 270 can be configured to adjust the total dust removal time or the initial dust removal time based on the dust concentration detected by the dust sensor 911. Therefore, dust can be removed more effectively in terms of energy saving.

[0393] Reference Figure 1 The dust sensor 911 may be disposed on the inner peripheral surface of the first chamber 100, and more particularly on the rear surface of the first chamber 100. Alternatively, the dust sensor 911 may be located in other locations, for example, near the air inlet port 115 or inside the inlet duct 221.

[0394] Figure 18 (c) can also be used to describe the movement of restoring the volume of clothing, such as a padded jacket filled with stuffing.

[0395] Clothing such as padded jackets can be filled with padding such as feathers, so that air in the spaces between the feathers can escape depending on use and storage. In this case, the volume of the clothing may decrease, and its insulation performance may also decrease. Volume can represent the thickness of clothing; therefore, restored volume can mean that the thickness of the clothing has increased compared to the thickness of the clothing before the clothing handling device 1000 performs volume movement.

[0396] Therefore, the clothes hanger rod 693 can reciprocate in a second mode within a predetermined first volume time TV1, such that the thickness of the clothing in the first chamber 100 is equal to or greater than the thickness of the clothing previously placed in the first chamber 100. After the first volume time TV1 expires, the clothes hanger rod 693 can reciprocate in a fourth mode within a predetermined second volume time TV2. After the second volume time TV2 expires, the clothes hanger rod 693 can reciprocate in a third mode within a predetermined third volume time TV3. During the predetermined total volume time, the clothes hanger rod 693 can repeatedly reciprocate in the second mode within the first volume time TV1, in the fourth mode within the second volume time TV2, and in the third mode within the third volume time TV3.

[0397] Here, total volume time refers to the total time required to perform volumetric motion.

[0398] As another embodiment of volumetric motion, the clothes hanger rod 693 can execute each mode only once, instead of repeating the second, fourth, and third modes. That is, the total volumetric time can be divided into three parts, such that the sum of the volumetric time TV1, the second volumetric time TV2, and the third volumetric time TV3 becomes the total volumetric time. Each of the second, fourth, and third modes can be executed once.

[0399] In this case, each of the second, fourth and third modes can be executed once, and the sum of the volume time TV1, the second volume time TV2 and the third volume time TV3 can be the total volume time.

[0400] Figure 19 (a) illustrates an example of a drying motion. A drying motion refers to the motion used to dry wet clothing, and typically, the clothing handling equipment 1000 can supply steam to the first chamber 100 via a steam generator 250 for wrinkle removal, deodorization, and sterilization. Thus, as steam penetrates the clothing in the first chamber 100, the clothing changes from a dry state to a damp state. Drying motion can be used to dry wet clothing.

[0401] In the early stages of the drying process, because the clothes are wet, they may be vigorously shaken using the second mode. In the middle stages of the drying process, because the clothes are slightly dry, they may be shaken using the third mode. In the final stages of the drying process, the clothes may be gently shaken using the first mode.

[0402] For this purpose, the steam engine 250 can supply steam to the first chamber 100 within a predetermined steam supply time. Thereafter, while driving the blower 220 and the heat pump 230 to dry the clothes in the first chamber 100, the clothes hanger rod 693 can reciprocate in a first mode for at least a portion of the predetermined total drying time TDt.

[0403] Alternatively, after the steam engine 250 supplies steam to the first chamber 100 within a predetermined steam supply time, while driving the blower 220 and heat pump 230 to dry the clothes in the first chamber 100, the clothes hanger rod 693 can reciprocate in a second mode within a predetermined first drying time TD1. After the first drying time TD1 expires, the clothes hanger rod 693 can reciprocate in a third mode within a predetermined second drying time TD2. After the second drying time TD2 expires, the clothes hanger rod 693 can reciprocate in a first mode within a predetermined third drying time TD3.

[0404] In the drying process, the sum of the first drying time TD1, the second drying time TD2, and the third drying time TD3 can be the total drying time TDt. The second mode, the third mode, and the first mode are each executed once, unlike other processes where multiple modes are repeatedly executed.

[0405] The drying process can be performed simultaneously with the operation of the heat pump 230, and the operation of the heat pump 230 can be confirmed by checking whether the compressor 234 is being driven. This is because the refrigerant needs to be compressed and circulated for heat exchange with the air drawn in from the first chamber 100.

[0406] Figure 19 (b) illustrates an example of a fur recovery movement. When fabrics are made of animal fur (such as rabbit hair) or synthetic fur, the appearance of the garment may deteriorate if the fur flattens. In such cases, a recovery movement can be used to restore the fur to its original state.

[0407] For recovery movement, mode B is used by default, and mode D can also be used. Mode D recovers the fallen fur by transmitting waves of low frequency and amplitude to the fur. Subsequently, mode B can vigorously shake the fur and supply air to the fur to recover it.

[0408] Therefore, since the recovery exercise can restore the fallen fur, the thickness of the clothing can be the same as or greater than the thickness of the clothing before the recovery exercise. This means that the thickness of the clothing is equal to or greater than the thickness before the fur recovery exercise.

[0409] That is, the hanger rod 693 can reciprocate in a fourth mode within a predetermined first recovery time TF1. After the first recovery time TF1 expires, the hanger rod 693 can reciprocate in a third mode within a predetermined second recovery time TF2. During the predetermined total recovery time, the hanger rod 693 can repeatedly reciprocate in the fourth mode within the first recovery time TF1 and repeatedly reciprocate in the third mode within the second recovery time TF2. In this case, the thickness of the garment after the total recovery time can be greater than or equal to the thickness of the garment before it is placed in the first chamber.

[0410] As another embodiment of the fur recovery movement, the coat hanger rod 693 can reciprocate in a fourth mode within a predetermined first recovery time TF1. After the first recovery time TF1 expires, the coat hanger rod 693 can reciprocate in a third mode within a predetermined second recovery time TF2. Each of the fourth and third modes can be performed only once, and the sum of the first recovery time TF1 and the second recovery time TF2 can be equal to the predetermined total recovery time.

[0411] That is, the fourth and third modes may not be executed repeatedly, but each of the third and fourth modes can be executed once by dividing the total recovery time into two parts. In this case, the thickness of the clothing after the total recovery time can be greater than or equal to the thickness of the clothing before it was placed in the first chamber.

[0412] The fur restoration exercise can be performed after steam is supplied by steam engine 250.

[0413] As described above, the garment handling device 1000 may include: a cabinet 10 including an inlet 11 on the front side; a first chamber 100 located inside the cabinet 10 and defining a space for holding garments through the inlet 11; a second chamber 200 located below the first chamber 100 and defining a space separate from the first chamber 100; a blower 220 located inside the second chamber 200 and including a blower fan 226 configured to draw air from the first chamber 100 to circulate air in the first chamber 100; a compressor 234 configured to compress a refrigerant; a heat pump 230 connected to the blower 220 and configured to discharge air dehumidified and heated by a heat exchanger (not shown) to the first chamber 100; and a steam engine 250 located in the second chamber 100. The second chamber 200 is internal and configured to generate and supply steam; a water supply tank 310, located in front of the second chamber 200 and configured to supply water to the steam engine 250; a drain tank 330, located in front of the second chamber 200 and configured to store condensate generated in the first chamber 100 and the heat pump 230; and a driver 610, wherein the driver may include: a vibrator 630 configured to support the motor 620 and vibrate alternately in a first and a second direction of rotation opposite to each other by rotation of the motor 620; and a motion converter 680 configured to rotate with the vibrator 630 and convert the vibration of the vibrator 630 to allow the clothes hanger rod 693 to reciprocate along a predetermined direction of motion associated with the clothes hanger rod 693. Depending on the number of times the motor 620 rotates when at least one of the blower 220, the heat pump 230, and the steam engine 250 is running, the clothes hanger rod 693 may reciprocate with different amplitudes and periods (or frequencies).

[0414] The garment handling equipment 1000 can perform various garment management functions as described above. For example, the garment handling equipment 1000 can perform wrinkle removal, drying, dust removal (or dusting), fur restoration, and volumetric movements. In order to perform various movements, the controller 270 can reciprocate the hanger rod 693 by combining various modes.

[0415] Reference Figure 2 and Figure 21The controller 270 may be configured to control the drive 610, the steam engine 250, the blower 220, the heat pump 230, the water supply pump 319 configured to supply water to the water supply tank 310, and the drain pump 339 configured to discharge condensate collected in a storage tank (not shown) to a drain tank 330. The controller 270 may be configured to control the rotational speed of the motor 620 included in the drive 610. The controller 270 may be configured to control the rotational speed of the blower fan 226 included in the blower 220. The controller 270 may be configured to control the compressor 234, which controls the refrigerant. Furthermore, the controller 270 may be configured to control the heater 2501, which is configured to heat the water contained in the storage tank 251 to generate steam.

[0416] The controller 270 can control the blower fan 226, compressor 234, heater 2501 and motor 620 based on multiple modes and movements to form a process for processing clothes, each of the modes and movements corresponding to a combination of multiple modes.

[0417] Figure 20 An example of a process for handling clothing based on the aforementioned patterns and movements is shown. Here, "process" can refer to a combination of movements performed within a predetermined process time. Therefore, the process time can be set to be longer than the movement time. The movement time can be set to be longer than or equal to the time required for each of one or more patterns necessary to perform the clothing management function.

[0418] Figure 20 (a) shows an example of a process that includes a steam supply process, a wrinkle removal process, and a drying process. The process may also include a preheating process prior to the steam supply process. Furthermore, the process may include a standby process between the steam supply process and the wrinkle removal process.

[0419] Here, the combination of the steam supply process, the standby process, and the wrinkle removal process can be referred to as the refurbishment process. This is because steam must be supplied and the clothes shaken by the reciprocating motion of the hanger rod 693 to perform sterilization, deodorization, and wrinkle removal.

[0420] In this document, a process (or step) refers to a sequential process distinguished by the operation of the blower fan 226, compressor 234, and heater 2501 (other than the motor 620 and the motion (or mode)). Multiple processes can be combined to form a single process. The operation of the motor 620 is already included in the mode (or motion). That is, even if the motion includes the same mode, the process can be distinguished based on whether the blower fan 226, compressor 234, and heater 2501 are operating.

[0421] In typical garment handling equipment, the hanger rod can reciprocate at the same frequency and cycle throughout the entire process. That is, the frequency of the hanger rod can be between 120 RPM (revolutions per minute or cycles per minute) and 200 RPM. Preferably, the hanger rod can reciprocate at 180 RPM. However, only the frequency changes, while the amplitude remains the same. This is because even if the RPM changes within the frequency range of the hanger rod, it has no significant impact on the garment handling performance.

[0422] Conversely, according to this disclosure, due to the harmonic excitation motion of the driver 610, the clothes hanger rod 693 can provide large amplitude variations based on various frequencies. Therefore, clothing can be managed more effectively based on various patterns with different frequencies and amplitudes.

[0423] The user can place clothing on the hanger rod 693 in the first chamber 100, close the door 400, and select a process via the input / output unit 950 located in front of the door 400. Depending on the process selected by the user, the controller 270 can be configured to heat the heater 2501 and convert the water in the storage tank 251 into steam. This is referred to as the preheating process.

[0424] That is, the preheating process can be performed before the steam supply process. The preheating process can be performed during the steam preheating time P1. The controller 270 measures the temperature of the water in the storage tank 251 via the steam temperature sensor 9131. If it is determined that the temperature has reached a level sufficient to generate steam, the controller 270 can proceed to the steam supply process.

[0425] Steam preheating time P1 refers to the heating time required for the steam engine 250 to reach the temperature capable of converting water into steam via the heater 2501. Theoretically, water will convert into steam at 100°C under atmospheric pressure.

[0426] Alternatively, when steam is simply generated and supplied to the first chamber 100, the preheating process can be considered as proceeding to the steam supply process. That is, the steam preheating time P1 is used to distinguish between the preheating process and the steam supply process, but the steam preheating time P1 may not be clearly defined.

[0427] Reference Figure 20 (b) During the preheating process or during the steam preheating time P1, the clothes hanger rod 693 may reciprocate in a second mode, and the blower fan 226 may rotate. Alternatively, the clothes hanger rod 693 and the blower fan 226 may operate only during a portion of the preheating process. Furthermore, during the steam preheating time P1, the clothes hanger rod 693 may be stopped and not operated.

[0428] The reason why the clothes hanger rod 693 operates in the second mode during the preheating process is to prevent clothes hanging on the clothes hanger rod 693 from falling off and covering the steam supply port 112 during the reciprocating motion of the clothes hanger rod 693. This is because if clothes block the steam jet during the steam supply process, the clothes may be damaged by the steam.

[0429] Therefore, during the preheating process, the hanger rod 693 needs to reciprocate with a smaller amplitude than in mode B. However, in order to remove dust from the clothes through the preheating process, the hanger rod 693 needs to reciprocate in mode C, which is a second mode specifically for dust removal.

[0430] When the steam preheating time P1 has elapsed, that is, when the steam engine 260 begins to generate steam, the controller 270 can be configured to start the steam supply process.

[0431] The steam supply process can be performed within a predetermined steam supply time P21. During the steam supply time P21, the hanger rod 693 can reciprocate in a fourth mode. This is to prevent clothes hanging on the hanger rod 693 from falling off during the reciprocating motion of the hanger rod 693 and blocking the steam supply port 112. Since the fourth mode, mode D, is effective for steam penetration and moisture absorption, the moisture content of the clothes can be increased, thereby improving wrinkle removal and deodorization performance.

[0432] Reference Figure 20 (b) During the steam supply time P21, the blower 226 rotates and the heater 2501 continuously heats the water in the reservoir 251, so that steam can be injected into the first chamber 100 through the steam supply port 112.

[0433] When the steam supply process is complete, the controller 270 can be configured to execute a standby process for a predetermined standby time P22. During the standby process, no steam is injected from the steam engine 250, and the clothes hanger rod 693 can reciprocate in mode D, which is the fourth mode. That is, the clothes hanger rod 693 can continue to maintain the fourth mode during both the steam supply process and the standby process.

[0434] During standby, the interior of the first chamber 100 may be filled with wet steam (wet water vapor or wet saturated water vapor) due to the steam supply process. Therefore, additional steam injection may not be necessary.

[0435] Reference Figure 20 (b) During the steam supply time P21, the blower 226 can rotate and the heater 2501 can stop heating.

[0436] The standby process allows steam to penetrate the clothing effectively, thus increasing its moisture content. Furthermore, the temperature of the clothing can rise due to the steam, which helps remove wrinkles during the subsequent process.

[0437] Since the standby process occurs between the steam supply process and the wrinkle removal process, the standby time P22 also occurs between the steam supply time P21 and the predetermined total wrinkle removal process time P3, which will be described later.

[0438] Typically, since the clothes hanger rod 693 reciprocates in mode four during both the steam supply process and the standby process, the steam supply process and the standby process can be referred to as the steam supply and standby process. The steam supply process and the standby process may differ only in whether steam is generated and injected through the heater 2501. (Refer to...) Figure 20 (b) During the steam supply process, heater 2501 generates and injects steam, but during the standby process, since steam is no longer needed, heater 2601 does not generate steam.

[0439] The controller 270 can be configured to switch from the steam supply process to the wrinkle removal process without a standby process, that is, to switch the mode of the hanger rod 693 to the mode used in the wrinkle removal process.

[0440] The wrinkle-removing process can also be referred to as a cooling process. This is because, although the heat pump 230 is not operating to dry the moisture in the first chamber 100 and the clothes, both the blower fan 226 and the hanger rod 693 operate during the wrinkle-removing process, causing the temperature inside the first chamber 100 to decrease over time. When the drying process begins after the wrinkle-removing process is complete, the heat pump 230 can be configured to cool and dehumidify the air in the first chamber 100 and reheat the air. In this case, if the temperature of the air in the first chamber is too high, the cooling efficiency of the heat pump 230 may be reduced. Therefore, it is necessary to lower the air temperature inside the first chamber 100 during the wrinkle-removing process used for the drying process. Therefore, the wrinkle-removing process can be referred to as a cooling process.

[0441] Furthermore, since the blower fan 226 and the hanger rod 693 operate during the wrinkle removal process, the wrinkle removal process can perform drying to a certain extent and reduce the temperature of the first chamber 100 and the clothes.

[0442] For the wrinkle removal process, the third mode, i.e., mode B, is used by default, but other modes can also be used. This is to change the position of nodes that may appear in the garment as described above. For this purpose, after the steam supply time and / or standby time, during at least a portion of the predetermined total wrinkle removal process time P3, the hanger rod 693 can reciprocate in the third mode, i.e., mode B.

[0443] Reference Figure 20 In one embodiment of the wrinkle removal process (a), during a first wrinkle removal process time P31 after the steam supply time and / or standby time have expired, the hanger rod 693 may reciprocate in a third mode. This is referred to as the first wrinkle removal process. After the first wrinkle removal process time P31 has expired, during a predetermined second wrinkle removal process time P32, the hanger rod 693 may reciprocate in one of a second mode and a fourth mode. This is referred to as the second wrinkle removal process.

[0444] The total wrinkle removal process time P3 can consist solely of the first wrinkle removal process time P31 and the second wrinkle removal process time P32. If a predetermined third wrinkle removal process time P33 is added, the hanger rod 693 can reciprocate in another mode, either the second or fourth mode, during the third wrinkle removal process time P33 after the second wrinkle removal process time P32 has expired. This is referred to as the third wrinkle removal process.

[0445] Reference Figure 20 (b) The blower fan 226 may be configured to rotate during the wrinkle removal process. The blower fan 226 can draw in and circulate humid air inside the first chamber 100 through the air intake port 115. During this process, although the heat pump 230 is not operating, the temperature inside the first chamber 100 may decrease due to air circulation, and condensation may occur due to this temperature. In addition, air circulation can dry the clothes in the first chamber 100 to some extent.

[0446] During the wrinkle removal process, the controller 270 can change the mode of the hanger rod 693 by changing the rotation speed of the driver 610.

[0447] Figure 20 (a) illustrates an embodiment with three different modes: Mode B (third mode), Mode C (second mode), and Mode D (fourth mode) are performed once during the wrinkle removal process. Alternatively, Mode B (third mode), Mode C (second mode), and Mode D (fourth mode) can be performed repeatedly during the total wrinkle removal process time P3. That is, during the total wrinkle removal process time P3, a mode configured by combining Mode B (third mode), Mode C (second mode), and Mode D (fourth mode) can be performed repeatedly.

[0448] After the total wrinkle removal process has elapsed, the controller 270 may be configured to reciprocate the hanger rod 693 in mode A (first mode) and perform the drying process by operating the heat pump 230. The heat pump 230 may be configured to draw in humid air from the first chamber 100 via the blower 220, dehumidify and heat the drawn-in air through heat exchange with the refrigerant, and supply the hot and dry air to the interior of the first chamber 100 through the air supply port 111.

[0449] Therefore, high temperature and dry air can reduce the humidity inside the first chamber 100, and the moisture in the clothes in the first chamber 100 can be evaporated, thereby drying the clothes.

[0450] The drying process can be performed during a predetermined drying process time P4. During the drying process time P4, the clothes hanger rod 693 can reciprocate in a first mode (mode A).

[0451] Reference Figure 20 (b) The blower fan 226 may be configured to rotate during the drying process, and the compressor 234 may be configured to operate to circulate the refrigerant used in the heat pump 230.

[0452] The processes described in this specification (hereinafter referred to as standard processes) are summarized in Table 3 below.

[0453] [Table 3]

[0454]

[0455]

[0456] Referring to Table 3, Mode D can effectively remove fine dust during the wrinkle removal process described above. In this case, if the garment is made of fur, the fur can be restored. Even if the garment is not completely dry during the wrinkle removal process, fine dust can still be removed using Mode D.

[0457] For these processes, not only the amplitude and frequency of the hanger rod 693 are considered, but also other components of the garment handling equipment 1000, such as... Figure 20 As shown in (b). See reference. Figure 20 (b) In the standard process, the blower fan can also rotate when the clothes hanger rod reciprocates.

[0458] In the standard process, the hanger rod 693 can reciprocate, while the blower fan 226 can rotate. That is, the amplitude and frequency of the hanger rod 693 can be changed so that the hanger rod 693 can reciprocate in a mode optimized for each process, while the air inside the first chamber 100 can be circulated by the blower fan 226.

[0459] During the drying process, compressor 234 can operate to compress and circulate the refrigerant, and in this case, hanger rod 693 can reciprocate in the first mode.

[0460] In each process, the rotational speed of the blower fan 226 can be changed similarly to that of the clothes hanger rod 693. For example, during the preheating process, the blower fan 226 can rotate at a first rotational speed. During the steam supply process and the standby process, the blower fan 226 can rotate at a second rotational speed and a third rotational speed, respectively. During the wrinkle removal process, the blower fan 226 can rotate at a fourth rotational speed. During the drying process, the blower fan 226 can rotate at a fifth rotational speed. The first, second, third, fourth, and fifth rotational speeds can be the same as or different from each other.

[0461] The rotational speed of the blower fan 226 during the first wrinkle removal process time P31 may be different from at least one of the rotational speed of the blower fan 226 during the second wrinkle removal process time P32 and the rotational speed of the blower fan 226 during the third wrinkle removal process time P33.

[0462] In each process, the rotational speed of the blower fan 226 can be changed according to the degree of dryness and the concentration of dust. That is, the controller 270 can detect the humidity and dust concentration in the first chamber 100 through the dryness sensor 915 or the dust sensor 911 to change the rotational speed of the blower fan 226.

[0463] Similarly, during the drying process, the rotational speed of the compressor 234 can be varied, rather than kept constant, depending on the humidity (dryness) and temperature inside the first chamber 100. That is, the controller 270 can detect the temperature and humidity inside the first chamber 100 via the temperature sensor 913 and the dryness sensor 915 installed in the inlet pipe 221 or the air intake port 115 to change the compression ratio of the compressor 234 and the rotational speed of the blower fan 226.

[0464] Figure 21 This is a block diagram schematically illustrating the control configuration of a garment handling apparatus according to an embodiment of the present disclosure.

[0465] The controller 270 can be located in the second chamber 200, but this is merely an example. That is, the controller 270 can be located anywhere, such as inside a door, or in the space between the cabinet and the first chamber, as long as the controller 270 can control the components of the garment handling equipment. The controller 270 can activate the power supply 900 based on user input to receive the power required to drive the garment handling equipment 1000. Furthermore, the controller 270 can deactivate the power supply 900 when the user-selected process or menu is completed.

[0466] In addition, the controller 270 can detect input from the user through the input / output unit located on the front side of the door (not shown) and display the current operating status of the garment handling equipment or any errors.

[0467] The controller 270 can receive information required for processing clothing via the sensor unit 910. For example, the sensor unit 910 may include a water level sensor 917. The water level sensor 917 can detect the water level in the water supply tank 310 and the water level in the drain tank 330. In addition, the water level sensor 917 can determine whether the water supply tank 310 and the drain tank 330 are installed in the tank mounting space 351.

[0468] The sensor unit 910 may also include a temperature sensor 913 for sensing temperature. The temperature sensor 913 may include a steam temperature sensor 9131 disposed in the steam engine 250. In addition, the controller 270 may determine the temperature inside the first chamber 100 by means of a temperature sensor (not shown) disposed in the inlet pipe 221 or near the air inlet port 115.

[0469] The sensor unit 910 may also include a dryness sensor 915 for detecting dryness. The dryness sensor 915 may be disposed on the inner peripheral surface of the first chamber 100 to measure the degree of dryness (or humidity) of the first chamber 100.

[0470] The sensor unit 910 may also include a dust sensor 911 for measuring the concentration of dust on the internal peripheral surface of the first chamber 100 or inside the air inlet port 115 or inlet pipe 221 as described above. Furthermore, the sensor unit 910 may also include a door sensor 919 for detecting whether a door is open or closed.

[0471] When the user-selected process is detected by the input / output unit 950, the controller 270 can control the blower 220, heat pump 230, steam engine 250, and drive 610 to sequentially execute predetermined movements or modes. Specifically, the controller 270 can control the rotational speed of the blower 226, the rotational speed of the motor inside the compressor 234, the on / off state of the heater 2501, and the motor 620 of the drive 610.

[0472] Figure 22 This is a flowchart illustrating a method for controlling the clothing management process. Assume... Figure 20 If the publicly disclosed process is a standard process, then... Figure 22The method shown corresponds to a method for controlling a standard process. When the user selects a standard process, a preheating step (S100) begins according to the control method of this disclosure. This step heats the water in the storage tank 251 via the heater 2501 within a predetermined steam preheating time P1 to supply steam via the steam engine 250. In the preheating step (S100), the clothes hanger rod 693 can reciprocate in a third mode. Furthermore, the blower fan 226 can rotate at a first rotational speed. The steam engine 250 can heat the water via the heater 2501, but may not inject steam into the first chamber 100. The preheating step (S100) can be performed during the predetermined steam preheating time P1.

[0473] After the steam preheating time P1 expires, a steam supply step (S300) can be executed according to the control method of this disclosure, which supplies steam generated in the steam engine 250 to the first chamber 100 through the steam supply port 112 within a predetermined steam supply time P21. In the steam supply step (S300), the clothes hanger rod 693 can reciprocate in a fourth mode, and the blower fan 226 can rotate at a second rotational speed.

[0474] After the steam supply time P21 expires, a standby step (S500) can be executed according to the control method of this disclosure, which exposes the clothes to steam without steam injection during a predetermined standby time P22. Considering that a sufficient amount of steam has been supplied during the steam supply step (S300), the purpose of the standby step (S500) is to fully expose the clothes to steam during the standby time P22, allowing the steam to penetrate the clothes and the clothes to absorb moisture. During the standby step (S500), the blower fan 226 can rotate at a third speed, and the clothes hanger rod 693 can reciprocate in a fourth mode, as in the steam supply step (S300). The heater 2501 can be turned off.

[0475] After the standby time P22 expires, according to the control method of this disclosure, a wrinkle removal step (S700) can be performed during a predetermined total wrinkle removal process time P3 to remove wrinkles from the garment. In the wrinkle removal step (S700), the blower fan 226 can rotate at a fourth rotation speed. The wrinkle removal step (S700) can be subdivided according to the mode of the hanger rod 693. According to the control method of this disclosure, the following can be performed: a first wrinkle removal step (S710), during a predetermined first wrinkle removal process time P31, in which the hanger rod 693 reciprocates in a third mode; a second wrinkle removal step (S720), during a predetermined second wrinkle removal process time P32 after the first wrinkle removal process time P31 expires, in which the hanger rod 693 reciprocates in a second mode; and a third wrinkle removal step (S730), during a predetermined third wrinkle removal process time P33 after the second wrinkle removal process time P32 expires, in which the hanger rod 693 reciprocates in a fourth mode.

[0476] In the wrinkle removal step (S700), the garment processing device 1000 can remove wrinkles from the garment, remove fine dust from the garment, increase the volume of the garment, and restore the fur that has fallen down.

[0477] After the total wrinkle removal process time P3 has elapsed, according to the control method of this disclosure, a drying step (S900) can be performed by operating the heat pump 230 during a predetermined drying process time P4 to dehumidify and heat the air inside the first chamber 100 to dry the clothes. According to the control method of this disclosure, the heat pump 230 can convert the humid air drawn from the first chamber 100 into high-temperature and dry air, and supply the high-temperature and dry air to the first chamber 100. Therefore, the humidity inside the first chamber 100 can be reduced, thereby drying the clothes. During the drying process time P4, the blower fan 226 can rotate at a fifth rotational speed. According to the control method of this disclosure, the compressor 234 can be driven to operate the heat pump 230.

[0478] This disclosure may be implemented in other specific forms without departing from the spirit and essential characteristics of this disclosure. Therefore, the above embodiments should be considered illustrative rather than restrictive in all respects. The scope of this disclosure should be determined by a reasonable interpretation of the appended claims, and all variations falling within the equivalent scope of this disclosure are included within its scope.
