Description

TECHNICAL FIELD

[0001] The present application relates to a laundry treating apparatus and a control method thereof. In more detail, the present application relates to a laundry treating apparatus capable of performing refresh operation such as sterilization, wrinkle removal, deodorization, drying, etc. of laundry by supplying steam and hot air to the laundry and a control method thereof. BACKGROUND

[0002] The laundry treating apparatus refers to an apparatus developed for washing, drying, and removing wrinkles generated on laundry in a home and a laundry room. The concept classified as the laundry treating apparatus includes a washing machine that washes laundry, a dryer that dries laundry, a washer-dryer that has both washing and drying functions, a laundry refresher that refreshes laundry, a steamer that removes wrinkles of laundry, etc.

[0003] Recently, a laundry treating apparatus, which is a laundry refresher capable of comfortably and cleanly maintaining laundry even without soaking laundry in water and washing it with a detergent, has appeared.

[0004] Such a conventional laundry treating apparatus is an apparatus that supplies one of hot air (hot wind) and steam of a high temperature to laundry to perform refresh operation such as deodorization of the laundry, drying of the laundry, and removal of wrinkles of the laundry.

[0005] Generally, such a laundry treating apparatus accommodates laundry by hanging an upper end of the laundry. Thereby, the laundry treating apparatus can arrange laundry in a height direction, so that a plurality of laundry can be hung in a width direction.

[0006] The laundry treating apparatus can be configured to move a structure (hereinafter, a moving hanger) that hangs the laundry inside. Thereby, the conventional laundry treating apparatus can shake the laundry using the moving hanger while supplying hot air and steam to the laundry, thereby having an effect of being able to shake off dust and foreign substances of the laundry.

[0007] On the other hand, the moving hanger is moved by the action of a motor or the like, so that if the characteristics of a current value or current output to the motor are analyzed, information of the laundry including the weight of the laundry can be grasped.

[0008] However, since the laundry treating apparatus like the present application does not have a rotating drum, the laundry is hung in a state of being vertically down in a length direction.

[0009] Therefore, in a case of shaking the laundry using the moving hanger, even if the weight of the laundry is the same, the waveform in which the laundry is shaken is different according to the length or material of the laundry, and the load of the moving hanger is affected.

[0010] In addition, there is a difference in the inertial force applied to the moving hanger when the laundry is shaken with a standing wave and when it is vibrated without forming a standing wave, and when it is vibrated without generating a wave form, and thus there is a problem in that it is difficult to sense the state of the laundry using the moving hanger.

[0011] In addition, the moving hanger is provided to not be directly connected to and rotated by the motor, but to shake the laundry with a driving frequency reduced from that of the motor and a more powerful torque than that of the motor using a pulley and a belt member, etc. At this time, due to the characteristics of the pulley and the belt member connection structure, the belt member is periodically moved and rotated between the upper and lower portions of the pulley, and the period can change according to the tension and length of the belt member.

[0012] As such, since the load of the motor is affected by the characteristics of the moving hanger system such as tension, it means that the current value of the motor is also affected.

[0013] Due to these limitations, unlike washing machines and dryers having a drum, the existing laundry treatment apparatus having a moving hanger has a problem in that it cannot sense the state of the laundry through information of the motor. SUMMARY

[0014] PROBLEMS TO BE SOLVED BY THE INVENTION

[0015] The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a laundry treatment apparatus capable of sensing one or more of the weight, length, and material of laundry by shaking a moving hanger of the laundry in a laundry care machine or the like in which the laundry is hung in a state of hanging in a length direction.

[0016] The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a laundry treatment apparatus capable of sensing one or more of the weight, length, and material of laundry by shaking a moving hanger of the laundry in a laundry care machine or the like in which the laundry is hung in a state of hanging in a length direction.

[0017] The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a laundry treatment apparatus capable of sensing one or more of the weight, length, and material of laundry by shaking a moving hanger of the laundry in a laundry care machine or the like in which the laundry is hung in a state of hanging in a length direction.

[0021] The moving hanger can be configured to, after the laundry is swung at a sensing speed for a sensing time, swing the laundry at a treating speed higher than the sensing speed in a state in which one or more of the steam and the hot air is supplied.

[0022] The moving hanger can include: a driving portion disposed in the inner cabinet outside the receiving space to provide a power to swing the laundry; a plurality of hooking portions for hanging the laundry inside the receiving space; a belt member connected to the driving portion to transmit the power; and a pulley connected to the belt member to transmit the power to the hooking portions.

[0023] If the driving portion is driven, the belt member can reciprocate between an upper end and a lower end of the pulley.

[0024] The sensing time can be equal to or longer than a period in which the belt member reciprocates between the upper end and the lower end of the pulley.

[0025] The sensing time can be set to be equal to or longer than a time in which the belt member rotates by a multiple of four.

[0026] If one or more of a tension and a material of the belt member changes, the sensing time can also change.

[0027] If the tension of the belt member increases, the sensing time can increase.

[0028] If the tension of the belt member increases, the sensing time can increase to be equal to or longer than a time in which the pulley rotates by a multiple of four.

[0029] If the tension of the belt member decreases, the sensing time can decrease.

[0030] If the tension of the belt member decreases, the sensing time can decrease to be equal to or longer than a time in which the pulley rotates by a multiple of four.

[0031] The laundry treating apparatus further includes: a door coupled to the cabinet to open and close the receiving space; and

[0032] a display portion provided in one of the cabinet and the door to display laundry information related to a weight, a length, and a material of the laundry. Even if the belt member is changed to a different material, as long as the clothes hung from the hanging portion are the same, the display portion can display the same clothes information.

[0033] Even if the belt member has been used for a long time or the tension of the belt member has changed or the environment such as temperature and humidity where the belt member is disposed has changed, as long as the clothes hung from the hanging portion are the same, the display portion can display the same clothes information.

[0034] The mobile hanger can be controlled to swing the clothes at a first sensing speed for a first sensing time, and after swinging the clothes at a second sensing speed higher than the first sensing speed for a second sensing time, swing the clothes at the processing speed.

[0035] The second sensing time can be set to be shorter than the first sensing time.

[0036] The display portion can display one or more of the weight, length, material of the clothes, and the execution time of the program for processing the clothes after the sensing time elapses.

[0037] The mobile hanger can be controlled such that the sensing time decreases as the sensing speed increases.

[0038] The mobile hanger can be controlled such that the sensing time increases as the sensing speed decreases.

In this specification, even different embodiments are given the same or similar reference numerals for the same or similar structures, and their descriptions are replaced by a first description. Unless otherwise expressly stated in the context, the singular expressions used in this specification include the plural expressions. Furthermore, in the process of describing the embodiments disclosed in this specification, if it is determined that the specific description of related well-known technologies would obscure the main idea of ​​the embodiments disclosed in this specification, detailed descriptions thereof are omitted. It should also be noted that the accompanying drawings are only for easy understanding of the embodiments disclosed in this specification, and the technical ideas disclosed in this specification are not limited by the drawings.

[0066] Figure 1 The appearance of the garment processing device 1 of the present invention is shown.

[0067] Reference Figure 1 (a) The garment handling apparatus of the present invention may include a housing 100 forming the appearance and a door 11 rotatably coupled to the housing 10.

[0068] The door 11 may have the same height and width as the front of the box 100, and may form the front of the clothing processing device 1.

[0069] The door 11 may be provided with an input unit that receives instructions that enable the garment processing device to operate, and may also be provided with a display unit that can display the operating status of the garment processing device to the outside in terms of vision, sound, etc.

[0070] Reference Figure 1 (b) Inside the box 10, an inner shell 20 with a storage space 21 for accommodating clothing may be provided. The inner shell 20 may have an opening 21 at the front for leading out and leading in clothing, and the opening 21 may be covered by the door 11.

[0071] The inner shell 20 can be made of plastic resin series, and can be made of reinforced plastic resin series that does not deform under air at a temperature higher than normal air or heated air (hereinafter, hot air) and steam or moisture.

[0072] The inner shell 20 can be configured such that its height is greater than its width. Therefore, the garment can be accommodated in the accommodating space 21 without being folded or wrinkled.

[0073] The garment handling apparatus 1 of the present invention may include a hanger portion capable of suspending garments in the receiving space 21 of the inner housing 20. The hanger portion may be disposed in the inner housing 20 and may be hung on a movable hanging rack 100 for suspending garments.

[0074] The movable hanger 100 can be configured to protrude into the upper inner surface of the inner housing 20, allowing the hanger portion to be suspended. The movable hanger 100 can be configured to reciprocate on the upper surface of the inner housing 20, shaking the clothing. The specific structure of the movable hanger 100 will be described later.

[0075] If the garment is suspended on the movable hanger 100, it can be suspended in the air inside the accommodating space 21, hanging downwards. Thus, the garment suspended in the accommodating space 21 can be evenly exposed to hot air and steam, and its own weight can remove wrinkles.

[0076] The garment handling apparatus of the present invention may further include a pressure part 40 attached to the inner surface of the door 11 and capable of fixing the garment.

[0077] The pressurizing part 40 can be configured to be rotatably attached to the inside of the door 11, pressing the clothing fixed to the inside surface of the door 11 against the inside surface of the door 11.

[0078] The pressure section 40 can generate the desired creases on both sides of the garment.

[0079] The garment processing apparatus of the present invention may further include a machine chamber 30, which supplies one or more of hot air and steam to the receiving space 21, or is equipped with various devices capable of purifying or dehumidifying the external air of the housing 10.

[0080] The mechanical chamber 30 may be configured to be separate or partitioned from the inner housing 20, and to be in communication with the inner housing 20.

[0081] The machine compartment 30 can be disposed at the lower part of the inner housing 20. Thus, if light-weight hot air and steam are supplied to the inner housing 20, the hot air and steam can be naturally supplied to the clothing.

[0082] The machine room 30 may include: a circulation pipe for circulating air inside the inner housing 20; and a plurality of heat exchangers disposed on the circulation pipe for cooling and condensing the air and heating the air.

[0083] The machine room 30 may have a heat pump system including a compressor connected to a plurality of the heat exchangers and capable of compressing a refrigerant for cooling or heating the air.

[0084] The machine compartment 30 may also have a steam supply section 50 capable of supplying steam to the interior of the inner housing 20. The steam supply section 50 can generate steam by heating water. Clothing housed inside the inner housing is exposed to the hot air generated in the heat pump system and the steam generated in the steam supply section 50, thereby enabling deodorization, sterilization, wrinkle removal, and drying.

[0085] A water tank 31 for supplying water for generating the steam and a drain tank 32 for collecting condensed water in the circulation pipe may be included in front of the machine room 30.

[0086] The water tank 31 and drain tank 32 can be detachably mounted in front of the machine room 30. Thus, even if the garment handling device of the present invention is not located near a water source or sewer, the user can load, unload, and transport the water tank 31 and drain tank 32 whenever needed.

[0087] The water tank 31 and the drainage tank 32 can be arranged side by side along the width of the machine room 30.

[0088] Additionally, the machine room 30 may also include a drawer 33 for storing items needed to care for the clothing. The drawer 33 may be designed to be pulled out of the machine room 30 and may have internal space for storing items such as an iron.

[0089] The garment handling device 1 of the present invention may have a mounting platform 60 inside the inner housing 20, which is capable of accommodating additional shelves. The mounting platform 60 may protrude from both sides of the inner housing 20 at the same height.

[0090] The mounting platform 60 may be provided with a light-emitting part that illuminates the interior of the inner housing 20. The light-emitting part is configured to illuminate the inner surface of the inner housing 20, thereby preventing glare.

[0091] Figure 2 This is a diagram illustrating one embodiment of the structure of the machine room.

[0092] The machine room 30 may include a pipe 90 disposed in the lower part of the inner housing 20, providing space for the heat pump system 80 and the steam supply unit 50, and providing a flow path for the air inside the inner housing 20 to circulate.

[0093] The pipe 90 can form a circulating flow path that communicates with the inlet and outlet of the inner shell 20 respectively, creating a space for air movement inside the inner shell 20. A blower fan can be installed inside the pipe 90. The blower fan can generate a pressure difference that draws in and exhausts air from the interior of the accommodating space 21.

[0094] The pipe may have a partially open rectangular shape at the top, and an additional cover may be attached to the top to complete the internal flow path. The pipe 90 may include: an inflow pipe 91, communicating with the inner housing 20 for air inflow; an outlet pipe 92, separated from the inflow pipe 91 and communicating with the inner housing 20 for air outflow; and a moving pipe 93, connecting the inflow pipe 91 and the outlet pipe 92 to form a flow path for air movement.

[0095] The heat pump system 80 may include: an evaporator 81 housed inside the duct 90 for cooling the air; a condenser 82 for heating the air passing through the evaporator 81 to generate hot air; a compressor 83 for compressing and heating the refrigerant passing through the evaporator 81 and supplying it to the condenser 82; and may also include an expansion valve for expanding and cooling the refrigerant passing through the condenser 82 and transferring it to the evaporator 81.

[0096] The evaporator 81 and the condenser 82 can be housed in the moving pipe 93, and the compressor 82 and the expansion valve can be configured outside the pipe 90.

[0097] The evaporator 81 and the condenser 83 can be configured in the direction of air movement. For example, the evaporator 81 can be configured to be closer to the inlet pipe 91 than the condenser 83, and the condenser 83 can be configured to be closer to the outlet pipe 92 than the evaporator 81.

[0098] The steam supply unit 50 can be configured inside the pipe 90.

[0099] The steam supply unit 50 can be disposed outside the pipe 90 so as not to obstruct the flow of air moving along the pipe 90.

[0100] The steam supply unit 50 may include: a steam generator 51 that receives and stores water and heats the water using an internal heater or the like to generate steam; and a steam nozzle 52 that supplies the steam generated in the steam generator 51 to the accommodating space 21.

[0101] The steam nozzle 52 can be configured to communicate with the inner housing 20 and can be arranged adjacent to the discharge pipe 92. The steam generator 51 can be mounted and supported on the upper part of the pipe 90 and can support the steam nozzle 52.

[0102] The steam supply unit 50 may also include a recovery pipe 54 connecting the steam nozzle 52 and the steam generator 51.

[0103] The recovery pipe 54 allows water that condenses and is not discharged from the steam nozzle 52 to be recycled back to the steam generator 51. The steam nozzle 52 can be positioned higher than the steam generator 51, allowing steam to be supplied to the inner housing 20 by density difference, and water to be recycled back to the steam generator 51 by gravity.

[0104] The steam nozzle 52 may be formed from a plastic material or the like instead of a simple hose, and may have one or more shell shapes that can contain steam, air, or water.

[0105] The steam supply unit 50 may further include a steam pipe 53 connecting the steam generator 51 and the steam nozzle 52. The steam generated in the steam generator 51 can be supplied along the steam pipe 53 to the interior of the steam nozzle 52 and to the interior of the inner housing 20.

[0106] The machine room 30 may also include a water supply unit 60 capable of supplying water for generating steam in the steam supply unit 50.

[0107] The water supply unit 60 may be configured to receive water from the water tank 31 located in front of the machine room 30 and supply it to the steam supply unit 50.

[0108] The water supply unit 60 may include: a water supply pipe 61 for receiving water from the water tank 31; a supply pipe 63 for supplying water from the water supply pipe 61 to the steam supply unit 50; and a water supply pump 62 for providing power to the water supply pipe 61 to supply water to the supply pipe 63.

[0109] The water tank 31 can be detachably installed in front of the pipe 90, and the water supply pump 62 can be installed outside the pipe 90.

[0110] The supply pipe 63 can be configured to be connected to the steam generator 51 and supply water to the steam generator 51.

[0111] Alternatively, the supply pipe 63 can be configured to communicate with the steam nozzle 52 and supply water to the steam nozzle 52. That is, the water supply unit 60 can also be configured to directly supply water to the steam nozzle 52 and indirectly supply water to the steam generator 51 through the recovery pipe 54. This simplifies the flow path structure.

[0112] The machine room 30 may also include a drainage section 70, which collects water condensed in the evaporator 81 into the drainage tank 32.

[0113] The drainage section 70 may include: a discharge pipe 71, which communicates with the lower part of the pipe 90 to discharge water collected at the lower part of the pipe 90 to the outside of the pipe 90; a drainage pump 72, which supplies water discharged to the discharge pipe 71 to a drainage tank 32; and a drainage pipe 73, which supplies water supplied to the drainage pump 72 to the drainage tank 32.

[0114] On the other hand, the drainage section 70 may also include a recovery pipe 74, which connects the pipe 90 and the drainage tank 32, guiding the water from the drainage tank 32 back into the pipe 90. Thus, even when the drainage tank 32 is full, leakage of the collected water from the drainage tank 32 to the outside can be prevented.

[0115] If the garment processing device of the present invention performs garment care operations such as sterilization, deodorization, wrinkle removal, and drying, hot air and steam can be supplied to the inner shell 20 at appropriate times through the mechanical chamber 30 to condense the moisture discharged from the inner shell 20 and collect it into the drain tank 32.

[0116] Figure 3 This is a diagram illustrating one embodiment of the movable hanger 100 of the garment handling apparatus of the present invention.

[0117] The movable hanger 100 of the present invention may include a power transmission part 400, which is disposed on the upper part of the inner housing 10 to shake the hanger 900.

[0118] The power transmission part 400 can extend through the upper surface of the inner housing. The power transmission part 400 can be in the shape of a rod, tube, or plate, etc., with a length longer than its thickness.

[0119] A hanging part 700 may be provided at the lower part of the power transmission part 400 for the clothes hanger 900 to be placed or hung. Thus, if the power transmission part 400 moves, the hanging part 700 moves, and as the clothes hanger 900 suspended on the hanging part 700 sways, the effect of the clothes shaking can be produced.

[0120] The hanging part 700 can be integrally provided with the power transmission part 400, or it can be formed as a separate part and installed on the power transmission part 400.

[0121] There may be a plurality of power transmission units 400, and there may also be a plurality of hanging parts 700 installed on the power transmission units 400. Thus, a large number of garments corresponding to the power transmission units 400 can be hung inside the inner housing 20 and cared for.

[0122] The movable gantry 100 may include a drive unit 200 that provides power to move the power transmission unit 400.

[0123] The drive unit 200 is configured to operate by receiving electrical energy, and therefore preferably avoids exposure to steam or hot air. Therefore, the drive unit 200 can be disposed between the upper surface of the inner housing 20 and the upper panel of the housing 10, thereby avoiding exposure to the receiving space 21.

[0124] The power transmission unit 400 can penetrate the upper part of the inner housing 20 and receive power from the drive unit 200. The power transmission unit 400 can penetrate the upper part of the inner housing 20 and extend downward, so that the lower end can be exposed to the receiving space 21.

[0125] On the other hand, the upper surface of the inner housing 20 can be configured to support the load of the power transmission unit 400 and the drive unit 200. However, the clothing is suspended from the power transmission unit 400 and moves, and the load on the drive unit 200 is also relatively heavy. Therefore, the clothing handling apparatus 1 of the present invention may further include a support unit 800 to stably mount the movable hanger 100 on the upper surface of the inner housing 20.

[0126] The support portion 800 can be disposed on the upper part of the inner shell 20, and is combined with and supported by the box body 1. The support portion 800 can be formed of a metal material with high rigidity.

[0127] The power transmission unit 400 and the drive unit 200 can be mounted on the support unit 800 and disposed on the upper part of the inner housing 20.

[0128] On the other hand, the drive unit 200 includes a motor that rotates the rotating shaft. The drive unit 200 may be configured to move the power transmission unit 400 using the power that rotates the rotating shaft.

[0129] However, relying solely on the rotation of the rotating shaft in place may not be sufficient to shake the power transmission unit 400 with adequate displacement.

[0130] Therefore, the movable hanger 100 may further include a displacement generating unit 300, which is coupled to the rotating shaft to generate sufficient displacement to move the power transmission unit 400.

[0131] The displacement generating unit 300 can be configured to connect the rotating shaft and the power transmission unit 400 to each other, thereby transmitting the power of the rotating shaft to the power transmission unit 400.

[0132] The displacement generating unit 300 may include an eccentric shaft that draws a trajectory larger than the diameter of the rotation axis and rotates. The eccentric shaft can generate a displacement that causes the power transmission unit 400 to reciprocate within a constant range.

[0133] Therefore, if the drive unit 200 operates, the power generated on the rotating shaft can be transmitted to the power transmission unit 400, so that the power transmission unit can reciprocate within a constant range.

[0134] The movable hanger 100 does not cause the power transmission part 400 to move back and forth, but rather causes the power transmission part 400 to rotate back and forth, thereby enabling the clothing to be shaken.

[0135] Specifically, the movable hanger 100 can cause the power transmission unit 400 to reciprocate within a constant angle range instead of moving linearly back and forth.

[0136] Therefore, the power transmission unit 400 can be configured to rotate back and forth at a precise position, and the clothing suspended on the power transmission unit 400 can also rotate back and forth only, without moving back and forth.

[0137] As a result, even if the clothing rotates inside the inner housing 20 due to the power transmission unit 400, the movement of its center of gravity inside the inner housing 20 can be limited. Therefore, even if the movable hanger 100 operates, the vibration generated inside the inner housing 20 can be drastically reduced, thereby minimizing noise generation.

[0138] The movable hanger 100 may also include a reciprocating rotating part 500, which converts the continuous rotational energy generated by the drive part 200 or the displacement generating part 300 into the reciprocating rotational motion of the power transmission part 400.

[0139] The reciprocating rotating part 500 can be configured to connect the displacement generating part 300 and the power transmission part 400 to each other. The reciprocating rotating part 500 connects the displacement generating part 300 and the power transmission part 400 to each other at a position higher than the inner housing 20, thereby preventing the clothing from being damaged by the movable hanger 100.

[0140] On the other hand, the movable hanger 100 can cause only one of the plurality of power transmission units 400 to reciprocate.

[0141] However, if only one power transmission unit 400 rotates, there is a risk that the clothes hanging on the rotating power transmission unit may collide with the clothes hanging on other power transmission units 400, resulting in damage to the clothes or damage to the movable hanger 100.

[0142] Therefore, the movable bracket 100 is preferably configured to allow all of the plurality of power transmission units 400 to rotate. Furthermore, the movable bracket 100 can cause the plurality of power transmission units 400 to rotate synchronously at the same angle. This prevents the power transmission units 400 from colliding with each other.

[0143] On the other hand, in the movable gantry 100, the power of the drive unit 200 is directly transmitted to all the plurality of power transmission units, which may be beneficial for controlling the rotation of all the power transmission units 400.

[0144] However, if there are multiple drive units 200 and each transmits power to its respective power transmission unit 400, not only will an excessive load be applied to the upper part of the inner housing 20, but it may also cause inconvenience in controlling multiple drive units 200.

[0145] Therefore, the movable hanger 100 can be configured to rotate a plurality of power transmission units 400 by means of a drive unit 200.

[0146] At this time, if the displacement generating unit 300 and the reciprocating rotation unit 400 are connected to transmit the power from one drive unit 200 to all power transmission units 400 respectively, the configuration and structure of the displacement generating unit 300 and the reciprocating rotation unit 400 become complicated, and therefore the reliability may be reduced.

[0147] Therefore, the movable hanger 100 of the present invention can be configured to transmit the power generated by the drive unit 200 to only a portion of the plurality of power transmission units 400. The reciprocating rotation unit 500 can be configured to transmit the power from the drive unit 200 or the displacement generating unit 300 to only a portion of the power transmission units 400. Therefore, the configuration of the reciprocating rotation unit 500 becomes simple, thus ensuring the reliability of power transmission.

[0148] On the other hand, the movable gantry 100 may also include a connecting part 600, which transmits the power transmitted to a specific power transmission part 400 to other power transmission parts 400.

[0149] For example, the connecting part 600 can connect a plurality of power transmission parts 400 to each other. Thus, if one power transmission part 400 rotates, the power transmission parts 400 adjacent to or separated from it can also rotate.

[0150] Specifically, the movable hanger 100 can be configured to transmit the power of the drive unit 200 to only one of the plurality of power transmission units 400, and transmit the power transmitted to the power transmission unit to the other power transmission units 400 through the connecting part 600.

[0151] The displacement generating unit 300 or the reciprocating rotation unit 400 can be configured to centrally transmit the power generated in a driving unit 200 to a power transmission unit 400. Furthermore, the connecting unit 600 can transmit the power transmitted to a specific power transmission unit 400 to all power transmission units 400.

[0152] The connecting part 600 may be formed of a rigid body and connect all power transmission parts 400. All power transmission parts 400 may be configured to rotate synchronously in the same direction and at the same angle due to the connecting part 600.

[0153] Therefore, the mobile hanger 100 of the present invention can be configured in a simple way, using a drive unit 200 to cause a plurality of power transmission units 400 to reciprocate at the same angle simultaneously or synchronously.

[0154] Figure 4 This is a diagram showing the structure of the movable hanger 100.

[0155] The movable hanger 100 may include: a drive unit 200, fixed to the upper part of the inner housing 20, providing power to move the power transmission unit; a plurality of reciprocating rotating units 500, respectively coupled to the plurality of power transmission units 400, receiving the power from the drive unit 200, and rotating to repeatedly change the direction of rotation; and a connecting unit 600, connecting the plurality of reciprocating rotating units to each other.

[0156] The connecting part 600 may include a single link that connects a plurality of the reciprocating rotating parts 500 and causes the plurality of the reciprocating rotating parts 500 to rotate as a whole.

[0157] The connecting part 600 can also be configured to connect a plurality of the power transmission parts 400.

[0158] If the connecting part 600 connects a plurality of the reciprocating transmission parts 500, the connecting part 600 can be positioned higher than the support part 800, thereby preventing exposure to the interior of the inner housing 20.

[0159] If the connecting part 600 is formed by a single link, the interference between the driving part 200 and the connecting part 600 can be minimized.

[0160] For example, the single link can be attached to the front or rear of the reciprocating rotating part 500, and the displacement generating part 300 or the driving part 200 described later can be arranged behind or in front of the reciprocating rotating part 500.

[0161] The connecting part 600 can be configured to reciprocate along the width direction of the inner housing 20, causing the plurality of reciprocating rotating parts 500 to rotate.

[0162] The drive unit 200 may include: a motor 210 for rotating the rotating shaft 210; a power shaft 240 for rotating together with the rotating shaft 210 if the rotating shaft 210 rotates; and a conversion unit 230 for connecting the power shaft 240 and the rotating shaft 210 and transmitting the rotational force of the rotating shaft 210 to the power shaft 240.

[0163] The motor 210 can be configured to be fixed to the upper part of the inner housing 20 to rotate the rotating shaft 220. However, the rotating shaft 220 rotates at a speed much faster than the appropriate cycle for the motor 210 to reciprocate the power transmission unit 400. Therefore, if the RPM of the rotating shaft is reduced, there is a risk that the output of the motor 210 may not be able to be transmitted to the power transmission unit 400.

[0164] To solve this problem, the conversion unit 230 directly transmits the output of the rotating shaft 220 to the power transmission unit 400, and reduces the RPM of the rotating shaft 220 for transmission.

[0165] The conversion unit 230 can be configured to rotate in connection with the rotating shaft 220, having a larger diameter than the rotating shaft 220. Thus, the conversion unit 230 can rotate at a slower RPM than the rotating shaft 220, and can increase and transmit the torque of the rotating shaft 220.

[0166] The power shaft 240 can be configured to rotate from the conversion unit 230, be separately arranged from the rotation shaft 230, and directly transmit power to the power transmission unit 400.

[0167] The reciprocating rotating part 500 can be configured to be combined with the power transmission part 400 and be able to rotate together with the power transmission part 400.

[0168] The reciprocating rotating part 500 may include a reciprocating lever 510, which is coupled to the upper part of the power transmission part 400 to rotate the power transmission part 400.

[0169] The reciprocating lever 510 may have a rib or rod shape with its rotation center connected to the support shaft 410.

[0170] The reciprocating levers 510 can be respectively connected to the upper ends of a plurality of the power transmission parts 400, and some of the reciprocating levers 510 can be connected to the conversion part 230 and receive power from the motor 210.

[0171] The reciprocating lever 510 can be configured such that if the conversion unit 230 is rotated by the motor 210, the reciprocating rotation angle is constant. The power transmission unit 400 can be configured to be coupled to the rotation center of the reciprocating lever 510 and rotate together with the reciprocating lever 510.

[0172] Multiple reciprocating levers 510 can be configured to be connected by a connecting part 600.

[0173] The connecting part 600 can connect one end of a plurality of reciprocating levers 510.

[0174] Therefore, if any one of the reciprocating levers 510 rotates, the connecting part 600 moves, thereby enabling the reciprocating levers 510 to rotate simultaneously and synchronously.

[0175] The power transmission unit 400 and the reciprocating lever 510 can be supported on the support unit 800. Additionally, the motor 210 and the conversion unit 230 can also be supported on the support unit 800.

[0176] Figure 5 This is a diagram showing the movable hanger 100 of the present invention separated from the inner housing 20.

[0177] The power transmission part 400 can extend from the upper part to the lower part of the inner housing, and the hanging part 700 can be attached to the lower part of the power transmission part 400.

[0178] The reciprocating rotating part 500 can be combined with each of the power transmission parts 400, and is attached to the upper part of the power transmission part 400, so that it can be easily connected to the drive part 200.

[0179] The power transmission unit 400 and the reciprocating rotation unit 500 are multiple and are arranged at a constant distance apart along the width direction of the inner housing.

[0180] The connecting portion 600 is configured to connect a plurality of the power transmission portions 400 or a plurality of the reciprocating rotating portions 500 to each other. Thus, the connecting portion 600 can be configured to allow the plurality of the power transmission portions 400 or the plurality of the reciprocating rotating portions 500 to rotate simultaneously as a whole.

[0181] The power transmission unit 400 may include a support shaft 410, which passes through the upper part of the inner housing 20 and is connected to the reciprocating lever 510.

[0182] The support shaft 410 can pass through the support portion 800 and protrude to the upper part of the support portion 800 or the upper part of the inner shell 20.

[0183] The power transmission unit 400 may include an auxiliary support unit 420, which is coupled to the support shaft 410 and protrudes into the receiving space. The auxiliary support unit 420 may be rod-shaped, with a hanging part 700 coupled to and fixed to its lower part.

[0184] The auxiliary support part 420 can be configured to be fixed to the support shaft 410 and rotate together with the support shaft 410. Thus, if the support shaft 410 rotates under the action of the reciprocating lever 510, the auxiliary support part 420 connected to the support shaft 410 can also rotate, thereby allowing the hanging part 700 to rotate left and right.

[0185] The reciprocating lever 510 may include: a main lever 511, which receives power directly from the drive unit 200 and reciprocates; and an auxiliary lever 512, which receives power from the main lever 511 through the connecting part 600.

[0186] The main lever 511 may be single and receive power directly from the drive unit 200.

[0187] In the drive unit 200, the motor 210 may include a vertical motor 211 coupled to the support unit 800 and a vertical rotation shaft 221 rotated by the vertical motor 211.

[0188] The conversion unit 230 may include: a drive pulley 231, which is coupled to the vertical rotation shaft 221 and rotates together with the vertical rotation shaft 221; a transmission pulley 232, which is coupled to the power shaft 240 and rotates the power shaft 240; and a belt member 233, which connects a portion of the outer peripheral surfaces of the drive pulley 231 and the transmission pulley 232.

[0189] The conversion unit 230 may further include a pulley support 224 that supports the drive shaft 240 and the transmission pulley 232 so that they can rotate. The pulley support 224 may be configured to support the transmission pulley 232 and the drive pulley 231 side by side and be placed in the support unit 800.

[0190] The power shaft 240 can be configured to transmit the power from the rotating shaft 220 to one end of the main lever 511.

[0191] The power shaft 240 is combined with the displacement generating unit 300 (described later), which enables the main lever 511 to reciprocate about the support shaft 410.

[0192] The connecting part 600 may include a bar 610, which connects the end of the main lever 511 that is not connected to the power shaft 240 to one end of the auxiliary lever 512.

[0193] The auxiliary lever 512 may be configured to be rotatably coupled to the support shaft 410, extend in one direction from the portion coupled to the support shaft 410 and connect to the connecting rod 610.

[0194] The connecting rod 610 may have a straight frame shape connecting one end of the main lever 511 and one end of a plurality of the auxiliary levers 512. In this case, one end of the main lever 511 and one end of the auxiliary levers 512 may be arranged side by side with respect to the connecting rod 610 or the width direction.

[0195] The connecting rod 610 can be a single one, which allows the main lever 511 and the auxiliary lever 512 to rotate simultaneously and synchronously around their respective support axes 410.

[0196] The inner housing 20 may have a through hole 23 for a portion of the support portion 800 to be housed, so that the power transmission portion 400 is exposed to the receiving space 22.

[0197] The through hole 23 may be provided on the upper surface 22 of the inner housing, and the through hole 23 may be provided in the direction in which the power transmission part 400 is configured.

[0198] For example, the power transmission units 400 may be spaced apart from each other along the width direction of the inner housing, and the through holes 23 may be arranged along the width direction of the inner housing.

[0199] The garment handling device 1 of the present invention may further include a support frame 12, which is disposed outside the inner shell and supports the box 1.

[0200] The support frame 12 is positioned at each location corresponding to the corner of the housing 1 or the corner of the inner shell 20, and can be formed of a metal material that maintains the appearance of the garment handling device. The two ends of the support portion 800 are placed and supported by the support frame 12, thereby preventing unnecessary impacts or loads from being transmitted to the upper surface 22 of the inner shell.

[0201] Figure 6 An exploded perspective view of the movable hanger 100 of the present invention is shown.

[0202] The power transmission part 400 may include: a support shaft 410, which passes through the upper surface of the inner housing 20 and is connected to the reciprocating lever 510; an auxiliary support part 420, which is connected to the support shaft 410 and protrudes into the receiving space 21; and a hanging part 700, which is connected to the auxiliary support part 420, for hanging the hanger part 900 or clothing.

[0203] The support shaft 410 has a cylindrical shape with a length longer than its diameter, and can be easily rotated by the reciprocating lever 510.

[0204] The diameter of the support shaft 410 can be much smaller than that of the auxiliary support 420, thereby allowing it to penetrate the inner housing or the support 800 with a smaller area. Therefore, the possibility of hot air or steam supplied to the accommodating space leaking into the upper part of the inner housing 20 can be further reduced.

[0205] The cross-sectional area of ​​the auxiliary support portion 420 is larger than that of the support shaft 410, and the length of the auxiliary support portion 420 can be longer than that of the support shaft 410. Therefore, the auxiliary support portion 420 ensures sufficient rigidity and area to support and rotate the hanging portion 700 and the hanger portion 900.

[0206] The support portion 800 may include a support plate 810 through which the support shaft 410 passes, and the support plate 810 is capable of supporting the drive portion 200. The support plate 810 is formed of a metal plate, thereby ensuring rigidity and durability, and can extend along the direction in which the plurality of power transmission portions 400 are arranged.

[0207] The support portion 800 may include: an extension body 812 extending upward from both ends of the support plate 810 to form a space between the drive portion 200 and the reciprocating rotating portion 500, which are disposed between the upper part of the inner housing 20 and the box 10; and a placement body 813 extending from the extension body 821 to be placed on the support frame 12.

[0208] The support portion 800 may include a shaft connection portion 820 through which the support shaft 410 passes.

[0209] The shaft connection portion 820 may be provided in a plurality of positions corresponding to the position where the power transmission portion 400 is configured, and may be spaced apart along the length direction of the support plate 810.

[0210] On the other hand, the support portion 800 may also include an auxiliary plate 880 attached to the lower part of the support plate 810. The auxiliary plate 880 may be formed of a resin series and is capable of accommodating a portion of the outer peripheral surface of the power transmission portion 400.

[0211] The auxiliary plate 880 may include: a plurality of receiving holes 882 disposed on the lower part of the support plate 810, accommodating the power transmission part 400 for rotation; a plurality of extending steps 883 extending wider from the receiving holes 882; and a fixing plate 881 extending from the extending steps 883, facing the support plate 810, and capable of engaging and fixing to the support plate 810.

[0212] The receiving hole 882 can be configured to be located at the upper end of the support shaft 410 or the auxiliary support portion 420 to prevent hot air or air from being discharged to the shaft connection portion 820. The extended step 883 can distribute the load or impact transmitted to the auxiliary plate 880, and can also prevent collision or interference with the receiving hole 882 and the hanger portion 900.

[0213] The support portion 800 may further include a mounting plate 820 disposed on the upper part of the support plate 810.

[0214] The mounting plate 820 can support the bearing mounted on the shaft connection portion 820, and at the same time can prevent the reciprocating lever 510 and the connecting portion 600 from colliding or rubbing against the support plate 810.

[0215] The mounting plate 820 may include: a mounting disc 861, which is mounted on the upper part of the support plate 810; and a mounting hole 862, which penetrates the mounting disc 861 and is disposed in the area corresponding to the shaft connection portion 820.

[0216] The reciprocating lever 510 may include: a main lever 511, which receives power directly from the drive unit 200; and an auxiliary lever 512, which receives power from the main lever 511 through the connecting part 600.

[0217] The main lever 511 and the auxiliary lever 512 can be configured to be coupled to their respective support shafts 410 and rotate around the support shafts 410 as the rotation center.

[0218] The connecting rod 610 may include: a connecting rod body 611, which is disposed on the main lever 511 and the auxiliary lever 512 so as to connect them to each other; and a connecting hook 612, which protrudes from the connecting rod body 611 and is rotatably disposed on the main lever 511 and the auxiliary lever 512.

[0219] The reciprocating lever 510 may include a connecting rod bearing 513, which is connected to one end of the main lever 511 and one end of the auxiliary lever 512, supporting the connecting hook 612 so that it can rotate.

[0220] If the connecting rod 610 rotates left or right, the main lever 511 or the auxiliary lever 512 can rotate back and forth.

[0221] The reciprocating rotating part 500 may further include a support bearing 530 capable of supporting the support shaft 410 or the reciprocating lever 510 so that it can rotate.

[0222] The support bearing 530 can accommodate the support shaft 410 so that it can rotate, and is positioned in the shaft connection portion 620.

[0223] The reciprocating lever 510 can be configured on the upper part of the support bearing 530.

[0224] The support bearing 530 can be arranged in multiple layers, and can be a ball bearing or an oilless bearing.

[0225] The mounting plate 860 can be configured to support the support bearing 530 and prevent the outer peripheral surface of the support bearing 530 from being exposed to hot air or moisture.

[0226] Alternatively, the auxiliary plate 880 may also be configured to be located at the lower part of the support bearing 530 to prevent the outer peripheral surface of the support bearing 530 from being exposed to hot air or moisture.

[0227] Figure 7 This is a diagram illustrating the operation mode of the movable hanger 100 of the present invention.

[0228] Reference Figure 7 (a) The main lever 511 may include a body 5111, which is coupled to the support shaft 410 and to the connecting rod 610.

[0229] The main body 5111 may include a main center hole 5115, which is connected to the support shaft 410 and allows the support shaft 410 to rotate. The main body 5111 can extend to both sides from the main center hole 5115.

[0230] One end of the main body 5111 may be provided with a main receiving hole 5112 for receiving power from the drive unit 200, and the other end may include a main transmission hole 5113 for the connecting rod 610 to be placed and engaged.

[0231] The main body 5111 may further include a stepped portion 5114 extending from the central hole to the main receiving hole 5112 and forming a step. Due to the stepped portion 51140, one end of the main body 5111 or the main transmission hole 5113 may be configured at a lower position than the main central hole 5115.

[0232] This ensures the length of the power shaft 240 or the eccentric shaft 310, which is located above the main center hole 5115, extending from the conversion section 230.

[0233] On the other hand, the auxiliary lever 512 may include: an auxiliary center hole 5125, which is coupled to the support shaft 410; and an auxiliary body 5121, which extends to one side from the auxiliary center hole 5125 and has an auxiliary transmission hole 5123 that is coupled to the connecting rod 610.

[0234] The auxiliary body 5121 may be configured to have a length shorter than that of the main body 5111.

[0235] The distance from the main center hole 5115 to the main transmission hole 5113 can be set to be the same as the distance from the auxiliary center hole 5125 to the auxiliary transmission hole 5123.

[0236] The connecting rod 610 can be placed on the upper part of the auxiliary transmission hole 5123 and the main transmission hole 5113 to connect the auxiliary lever 512 and the main lever 511 to each other.

[0237] Reference Figure 7In (b), the drive unit 200 can be configured such that the power shaft 240 is inserted into the main receiving hole 5112. Thus, the main receiving hole 5112 can be rotated left or right by directly rotating the power shaft 240.

[0238] In other words, relying solely on the rotation of the power shaft 240 may not be sufficient to generate enough displacement for the main receiving hole 5112 to rotate left and right with respect to the main center hole 5115.

[0239] Therefore, the movable hanger 100 of the present invention may include a displacement generating part 300, which is coupled to the power shaft 240 and is capable of generating a displacement larger than the rotation radius of the power shaft 240.

[0240] The displacement generating unit 300 can be configured to convert the in-situ rotational motion of the power shaft 240 into a reciprocating displacement motion within a constant range. This displacement motion can be transmitted to the reciprocating rotation unit 500, thereby enabling the power transmission unit 400 to reciprocate.

[0241] For example, the displacement generating unit 300 may also include an eccentric shaft 310 that extends to the power shaft 240 and rotates along a trajectory with a constant radius.

[0242] The diameter of the eccentric shaft 310 can be set to be smaller than the diameter or width of the main receiving hole 5112. Therefore, the eccentric shaft 310 can be inserted into and supported in the main receiving hole 5112.

[0243] However, the constant radius of rotation of the eccentric shaft 310 can be set to be greater than the width or diameter of the main receiving hole 5112. As a result, if the eccentric shaft 310 rotates, the main receiving hole 5112 is pushed by the eccentric shaft 310, thereby allowing it to move left and right with reference to the main center hole 5115.

[0244] As a result, if the eccentric shaft 310 rotates in a specific direction x, the main receiving hole 5112 of the main body 511 will reciprocate along a constant direction y. Consequently, the central hole 5115 of the main body can rotate in the same direction as the main receiving hole 5112, and the main transmission hole 5113 can reciprocate in the opposite direction z to the constant direction.

[0245] If the eccentric shaft 310 rotates, the support shaft 410 can reciprocate together with the main center hole 5115, thereby allowing the power transmission part 400 to reciprocate. The main transmission hole 5113 can also reciprocate to move the connecting rod 610 back and forth, thus allowing the auxiliary lever 521 to reciprocate around the auxiliary center hole 5125 and the support shaft 410. The power transmission part 400 connected to the auxiliary lever 521 can also reciprocate.

[0246] The power transmission part 400 may have a thread along the periphery of the upper part of the support shaft 410.

[0247] The main transmission hole 5113 and the auxiliary center hole 5125 can be directly connected and fixed to the support shaft 410 using threads or the like.

[0248] However, the power transmission unit 400 may also include a transmission coupling part 415, which is engaged with the thread of the support shaft 410 so that after the support shaft 410 passes directly through the main transmission hole 5113 and the auxiliary center hole 5125, the support shaft 410 is fixed to the main transmission hole 5113 and the auxiliary center hole 5125.

[0249] Therefore, the support shaft 410 and the reciprocating lever 510 are joined by the transmission joint 415, so that the support shaft 410 and the reciprocating lever 510 can rotate simultaneously.

[0250] Figure 8 This is a diagram illustrating the operation of the movable hanger 100 of the present invention.

[0251] Reference Figure 8 (a) The main receiving hole 5112 of the main lever 511 can rotate to the left (number 1) with the main center hole 5115 as a reference under the action of the rotation of the eccentric shaft 310.

[0252] If the main receiving hole 5112 rotates to the left, the main center hole 5115 can also rotate counterclockwise (number 2). During this process, the power transmission part 400 connected to the main center hole 5115 can rotate counterclockwise.

[0253] The main receiving hole 5113 rotates counterclockwise with respect to the main center hole 5115. At this time, the connecting rod 610 can move to the right (serial number 3) as the main receiving hole 5113 moves.

[0254] If the connecting rod 610 moves to the right, the auxiliary receiving hole 5123 of the auxiliary lever 512 rotates counterclockwise with respect to the auxiliary center hole 5125. The connecting rod 610 is connected to a plurality of the auxiliary levers 512, so all the auxiliary levers 512 also rotate counterclockwise (number 4).

[0255] If the auxiliary lever 512 rotates counterclockwise, the power transmission part 400 connected to the auxiliary center hole 5125 also rotates counterclockwise (number 5).

[0256] Reference Figure 8 (b) The main receiving hole 5112 of the main lever 511 can rotate to the right (number 1) with the main center hole 5115 as a reference under the action of the rotation of the eccentric shaft 310.

[0257] If the main receiving hole 5112 rotates to the right, the main center hole 5115 can rotate clockwise (number 2). During this process, the power transmission part 400 connected to the main center hole 5115 can also rotate clockwise.

[0258] The main receiving hole 5113 rotates clockwise with respect to the main center hole 5115. At this time, the connecting rod 610 can move to the left (serial number 3) as the main receiving hole 5113 moves.

[0259] If the connecting rod 610 moves to the left, the auxiliary receiving hole 5123 of the auxiliary lever 512 rotates clockwise with respect to the auxiliary center hole 5125. The connecting rod 610 is connected to a plurality of the auxiliary levers 512, so all the auxiliary levers 512 also rotate clockwise (number 4).

[0260] If the auxiliary lever 512 rotates clockwise, the power transmission part 400 connected to the auxiliary center hole 5125 also rotates clockwise (number 5).

[0261] If this process is repeated, the main lever 511 receives power from the drive unit 200 and rotates back and forth in the clockwise and counterclockwise directions, thereby causing the power transmission unit 400 connected to the main lever 511 to rotate back and forth, and causing the connecting rod 610 to move back and forth left and right.

[0262] The connecting rod 610 can move back and forth to make the auxiliary lever 512 rotate back and forth, and can also make the power transmission part 400 connected to the auxiliary lever 512 rotate back and forth.

[0263] The connecting rod 610 is formed of a rigid body, and the auxiliary lever 512 and the main lever 511 are connected to the connecting rod 610 at a position that is equidistant from the support shaft 410.

[0264] Therefore, due to the connecting rod 610, the auxiliary lever 512 and the main lever 511 can reciprocate at the same angle. As a result, all power transmission parts 400 can rotate simultaneously and synchronously at the same angle, and the angles of reciprocation can also be the same for each other.

[0265] The main lever 511 can be configured between the auxiliary levers 512. Furthermore, the auxiliary levers 512 can be symmetrically configured with respect to the main lever 511. Thus, the load can be evenly applied to both sides of the connecting rod 610 connected to the main lever 511.

[0266] However, as long as the power of the main lever 511 can be transmitted to the auxiliary lever 512, the main lever 511 and the auxiliary lever 512 can be configured in any arrangement or order.

[0267] Figure 9 This is a diagram illustrating the operation of the movable gantry of the present invention.

[0268] Reference Figure 9 (a) If the drive unit 200 operates, the power transmission unit 400 can rotate to the right under the action of the reciprocating rotation unit 500. At this time, the plurality of power transmission units 400 connected to the connecting unit 600 can also rotate to the right.

[0269] Reference Figure 9 (b) If the drive unit 200 operates further, the power transmission unit 400 can rotate to the left under the action of the reciprocating rotation unit 500. At this time, the plurality of power transmission units 400 connected to the connecting unit 600 can also rotate to the left.

[0270] By repeating this process, the power transmission unit 400 can rotate left and right.

[0271] The power transmission unit 400 can rotate left and right while being fixed in a precise position. The power transmission unit 400 can be fixed to the support unit 800 so that there is no change in position when rotating.

[0272] The power transmission unit 400 can be fixed in a position that does not move, based on the vertical direction, the front-back direction, and the width direction.

[0273] However, the power transmission unit 400 can be configured to rotate left and right about the vertical or vertical direction of its extension. As a result, if the drive unit 200 is driven, the hanging part 700 can reciprocate left and right about the power transmission unit 400 without moving its position.

[0274] Reference Figure 9 (c) The hanger portion 900 may include a hook portion 910 suspended from the hanging portion 700 and a placement portion 900 coupled to the hook portion 910. A surface portion 950 for preventing clothing from slipping may be provided on the surface of the placement portion 950.

[0275] The mounting portion 950 can be symmetrical about the hook portion 910. The hanger portion 900 can be suspended from the hanging portion 700, so that the mounting portion 950 is arranged in the front-to-back direction.

[0276] If the power transmission unit 400 rotates to the left, then the hanger unit 900 can rotate to the left with the hook unit 910 as a reference, and the left side of the mounting unit 950 can rotate to the left, while the right side of the mounting unit 950 can rotate to the right. At this time, the angle I of rotation of the left side of the mounting unit 950 can be the same as the angle θ of rotation of the right side of the mounting unit 950, and the distance the left side of the mounting unit 950 moves can be the same as the distance the right side of the mounting unit 950 moves.

[0277] As a result, with the hanger portion 900 as a reference, the weight and force moving to the left can be the same as the weight and force moving to the right and thus cancel each other out.

[0278] Similarly, even if the power transmission unit 400 rotates to the right, the weight and force moving to the left relative to the hanger unit 900 are the same as the weight and force moving to the right, thus canceling each other out.

[0279] As a result, even if the power transmission unit 400 rotates, the forces applied to the hanger unit 900 can cancel each other out, thereby minimizing the vibration or excitation forces and inertial forces generated in the hanger unit 900 itself. Consequently, the inertial forces generated in the plurality of power transmission units 400 can be minimized, thereby minimizing the vibration or noise generated throughout the movable hanger 100, and drastically reducing the vibration or noise generated throughout the entire garment handling device 1.

[0280] As a result, even if the drive unit 200 is driven at maximum output, the vibration generated throughout the movable hanger 100 or the clothing handling device 1 may be minimal.

[0281] Conversely, each surface of the garment suspended on the hanger section 900 rotates and shakes from side to side, thus ensuring a large shaking force.

[0282] Alternatively, the power transmission unit 400 may be configured to penetrate the inner housing 20 to receive the power and reciprocate in clockwise and counterclockwise directions.

[0283] The power transmission unit 400 can be configured to rotate back and forth left and right while its position is fixed at the upper part of the receiving space 21.

[0284] The power transmission unit 400 is fixed in the up-down and left-right directions. In addition, the upper and lower parts of the power transmission unit 400 are fixed in the up-down and left-right positions.

[0285] That is, the power transmission unit 400 can be configured to reciprocate at a constant angle of less than one revolution when the rotation center is fixed.

[0286] No matter how fast the power transmission unit 400 rotates, its position remains fixed.

[0287] Therefore, vibration and noise generated by the power transmission section 400 inside the inner housing 20 can be minimized.

[0288] Figure 10 This is a diagram illustrating the system in operation of the movable gantry.

[0289] The garment processing apparatus of the present invention may include a control unit C, which executes any procedure for processing the garment by driving one or more of the movable hanger 100, the steam generator 50, and the heat pump system 80.

[0290] The control unit C can execute various programs consisting of a series of control methods, which can perform care operations such as drying, deodorizing, sterilizing, and wrinkle removal on the clothing.

[0291] The garment handling apparatus of the present invention may further include: an input unit I for receiving instructions from the control unit C to execute the program; and a display unit D for receiving information from the control unit C and displaying the status of the garment handling apparatus. The input unit I and the display unit D may be disposed on one of the housing 10 and the door 11.

[0292] If the control unit C receives an instruction to execute the program or an instruction to supply power from the input unit I, the control unit C can activate the movable hanger 100.

[0293] The control unit C can drive the drive unit 200 to move the movable hanger 100. The drive unit 200 can be configured to receive instructions from the control unit C and cause the transmission unit 300 to move to shake the clothing.

[0294] The control unit C can be configured to provide signals that directly drive the drive unit 200, and also receive information from the drive unit 200.

[0295] The garment processing device of the present invention may include a current detection unit 260, which receives electrical information such as current and voltage output from the drive unit 200 and transmits it to the control unit C.

[0296] Additionally, the garment handling apparatus of the present invention may include a position sensing unit 270, which senses the position of the power transmission unit 400 or the connecting unit 600 and transmits it to the control unit C. The position sensing unit 270 may also be configured to sense the rotation angle of the rotating shaft 210 and the power shaft 240, or the position of the eccentric shaft 310.

[0297] The garment processing apparatus of the present invention can be configured to sense one or more garment information, including the weight, length, material, properties, and type of the garment, based on the control system driving the movable hanger 100. The garment processing apparatus of the present invention can optimize and adjust one or more of the intensity, type, time, and option values ​​of the garment refresh procedure based on the sensed garment information.

[0298] For example, the clothing handling apparatus of the present invention can operate by adjusting one or more of the following based on the sensed clothing information: the drive speed of the movable hanger 100, the drive time and drive output of the steam generator 50, and the drive time and drive rpm of the heat pump 80.

[0299] The driving speed of the movable hanger 100 can be defined as one of the driving rpm of the driving unit 200 and the moving speed of the power transmission unit 400.

[0300] The driving speed of the movable hanger 100 can also be defined based on the speed at which the clothing is shaken or the speed at which the upper end of the clothing is shaken.

[0301] The garment processing apparatus of the present invention can adjust the mechanical force applied to the garment, the amount of steam supplied to the garment and the steam exposure time, and the temperature of the hot air supplied to the garment and the hot air exposure time according to the sensed garment information.

[0302] Therefore, the clothing processing apparatus of the present invention can process clothing according to the clothing information and in a matching manner, rather than directly executing a uniform program unrelated to the clothing information.

[0303] Of course, in order to sense the information about the clothing, the clothing processing apparatus of the present invention may have additional sensing units. For example, the clothing processing apparatus of the present invention may use a load sensor or the like installed on the movable hanger 100 to sense the weight of the clothing, and may use a radar sensor such as a light or propagation sensor inside the inner housing or the position sensing unit 270 to sense the length, material, type, etc. of the clothing.

[0304] However, if multiple sensing units that directly sense the information of the clothing are installed in the clothing processing device, not only will the production and maintenance costs increase, but it may also be difficult to maintain the durability of the sensing units, considering the characteristics of hot air and steam being supplied to the inside of the clothing.

[0305] Therefore, the garment handling apparatus of the present invention can be configured such that the control unit C drives the movable hanger 100 and calculates electrical information applied to or output from the movable hanger 100.

[0306] The electrical information may include one or more of the following: current value, power value, waveform, amplitude, and period of current or power applied to or output from the motor unit 210 when the drive unit 200 is driven.

[0307] Typically, washing machines and dryers calculate the weight of the clothes by analyzing the current output from the drive unit that rotates the drum containing the clothes. This is because the clothes in the washing machine and dryer clump together inside the drum regardless of their type, material, or length. In other words, the washing machine and dryer determine the current value required to rotate the drive unit, or the current value output from the drive unit, based on the weight of the clothes, regardless of their state; therefore, there are almost no variables that affect the current value.

[0308] However, in the garment care device of the present invention, the garments are arranged such that only the upper part of the movable hanger 100 is suspended, while the rest hangs down in the receiving space 21. As a result, if the movable hanger 100 is driven, the garments vibrate along the height direction and form various waveforms.

[0309] In other words, the clothing vibrates independently of the movable hanger 100, and the vibration generated in the clothing in this way is the load of the movable hanger 100.

[0310] The amplitude or vibration pattern generated in the clothing affects the current or power value applied to or output from the drive unit 200.

[0311] As a result, if the garment handling apparatus of the present invention simply senses the weight of the garment using only the electrical information when the movable hanger 100 is driven, the reliability may be greatly reduced.

[0312] For example, depending on the length of the garment, even when vibrating at the same frequency, the waveform or amplitude of the vibration will differ. Furthermore, even if the weight of the garments is the same, if their lengths differ, the waveform or amplitude of each garment's vibration may differ even if each garment shakes at the same frequency. As a result, even if the motor 210 of the drive unit 200 is driven at the same speed, if the lengths of the garments suspended by the power transmission unit 400 are different, the control unit is highly likely to calculate that the weights of the garments are different.

[0313] If the movable hanger 100 is driven slowly, the garment can move and sway along the movable hanger 100 as a whole from top to bottom. However, if the movable hanger 100 is driven quickly, the upper part of the garment begins to sway with large amplitude and periodicity, but the lower part of the garment fails to keep up with the vibration of the upper part of the garment in time or is delayed in keeping up due to inertial force, which may result in the garment bending or folding back.

[0314] Furthermore, when the driving frequency of the movable hanger 100 or the power transmission unit 400 corresponds to the resonant frequency of the garment, the area of ​​vibration and the fixed area of ​​the garment can vibrate with a fixed standing wave. If the garment vibrates with a standing wave, it will transmit an inertial force different from that when the garment does not vibrate with a standing wave to the movable hanger 100, which may cause a large error in the electrical information of the drive unit 200.

[0315] Furthermore, even if the garment forms a standing wave and vibrates, the multiple n of the standing wave generated by the garment may be different depending on the driving speed of the drive unit 200 or the power transmission unit 400. In this case, even if the garment vibrates with the same standing wave, it may provide different inertial forces to the movable hanger 100, which may result in different electrical information of the drive unit 200.

[0316] In summary, when the movable hanger 100 is driven, the electrical information applied to or output from the drive unit 200 is greatly affected by the weight of the garment and its vibration characteristics. Since the vibration characteristics of the garment depend on the drive speed of the drive unit 200 or the power transmission unit 400, the factors affecting the electrical information that can be sensed in the drive unit 200 can be considered as the weight of the garment and the drive speed of the drive unit 200 or the power transmission unit 400.

[0317] 317 Therefore, the garment processing apparatus of the present invention can be configured to calculate garment information including at least one of the weight and length of the garment, taking into account the weight of the garment and the vibration characteristics of the garment based on the driving speed of the drive unit 200 or the power transmission unit 400.

[0318] Figure 11 This diagram illustrates an embodiment of the garment handling apparatus of the present invention, in which the control unit calculates garment information sensed by a movable hanger.

[0319] The garment handling device of the present invention is driven by the control unit C to drive the drive unit 200 to move the movable hanger 100.

[0320] The drive unit 200 can make the rotating shaft 210 and the power shaft 240 rotate continuously in one direction, so that the power transmission unit 400 can be moved back and forth by the displacement generating unit 300 to shake the clothes.

[0321] The reciprocating movement of the power transmission unit 400 includes at least one of the following: linear reciprocating movement, reciprocating rotational motion at a constant angle, pendulum motion, and periodic motion.

[0322] In other words, regardless of the embodiment in which the movable hanger 100 is configured, the movable hanger 100 provided in the garment handling device of the present invention can cause the power transmission unit 400 to reciprocate by controlling the drive unit 200.

[0323] In the garment handling apparatus of the present invention, when the movable hanger 100 is driven, regardless of the operation of the drive unit 200 and the transmission unit 300, the power transmission unit 400 is able to change the moving direction of the hanging part 700 twice in each cycle.

[0324] Whenever the direction of movement of the hanging part 700 and the clothes suspended on the hanging part 700 via the hanger part 900 changes, a considerable inertial force is generated. As a result, the hanging part 700 transmits the inertial force to the power transmission part 400 twice during one reciprocating cycle.

[0325] If the hanging part 700 reciprocates, the inertial force is transmitted independently of the load that causes the power transmission part 400 to move. The drive part 200 bears an additional load each time it periodically receives the inertial force.

[0326] As a result, as the drive unit 200 is driven, the garment generates the inertial force at a constant cycle, so the electrical information output from or received by the drive unit 200 can include a graph that can indicate the motion state of the hanging part 700.

[0327] Therefore, the control unit C of the garment processing apparatus of the present invention can calculate garment information including the vibration characteristics of the garment by analyzing the electrical information itself and the inertial force of the garment that can be sensed in the electrical information.

[0328] Furthermore, the control unit C can identify the cycle of the reciprocating movement of the hanging part 700 by sensing the inertial force applied to the drive unit 200, and identify the time point at which the hanging part 700 changes its direction of movement.

[0329] In addition, the control unit c can also sense the movement state of the clothing by sensing the magnitude of the inertial force and the change in the magnitude of the inertial force.

[0330] For example, if the control unit C receives the electrical information from the drive unit 200, the clothing processing apparatus of the present invention can extract the DC component and the AC component from the electrical information.

[0331] The DC component is an electrical signal with a constant absolute value, containing information about the load required to drive the drive unit 200 at a specific RPM. The heavier the garment, the greater the load required by the drive unit 200; therefore, the DC component can contain information reflecting the weight of the garment. Thus, the control unit C can obtain the information needed to calculate the weight of the garment by analyzing the DC component.

[0332] The AC component, as an electrical signal with a constant period, can contain information reflecting the vibration characteristics of the garment. During the vibration of the garment or the periodic change of the hanging part 700's direction of movement, the inertial force can be transmitted to the drive part 200, and the transmitted inertial force can be reflected in the AC component.

[0333] The control unit C can obtain the information needed to calculate the vibration characteristics and vibration period of the clothing by analyzing the AC components.

[0334] In cases where the AC component has a constant period, the second harmonic signal is most prominent in the periodic graph, retaining reliable information about the period. Therefore, the control unit C can preferentially extract or filter the second harmonic from the sensed AC component and analyze the vibration characteristics of the clothing in detail using the second harmonic.

[0335] The vibration characteristics of the garment can vary depending on its length and material. Therefore, these vibration characteristics include garment information related to its length and material. Consequently, the control unit C can also calculate garment information such as its length and material using the vibration characteristics analyzed through the AC component analysis.

[0336] Furthermore, the control unit C can further track changes in the electrical information of the sensing drive unit 200 by changing the drive speed of the drive unit 200 or the power transmission unit 400, thereby confirming the previously sensed clothing information and recalculating the clothing information.

[0337] As a result, the control unit C can calculate the clothing information by analyzing the absolute value of one or more electrical information, including current and voltage, when driving the drive unit 200, and the vibration characteristics of the electrical information.

[0338] Figure 12 This is a diagram illustrating an embodiment of the garment processing apparatus of the present invention calculating the weight of garments.

[0339] Reference Figure 12 (a) The garment handling apparatus of the present invention can be configured such that a long garment L is suspended inside the accommodating space 20 by a movable hanger 100.

[0340] Reference Figure 12 (b) In the garment handling apparatus of the present invention, the movable hanger 100 can drive the drive unit 200 to reciprocate the power transmission unit 400. The power transmission unit 400 is coupled with the hanging part 700, and the hanging part 700 is provided with the hanger part 900, so the garments hanging on the hanger part 900 can reciprocate and vibrate together with the power transmission unit 400.

[0341] The movable hanger 100 can be driven at a specific frequency to shake the clothing supported on the power transmission unit 400.

[0342] The term "driven at a specific frequency" for the movable hanger 100 means that the movable hanger 100 reciprocates at a specific cycle. That is, "driven at a specific frequency" means that the power transmission unit 400, which actually moves the clothing back and forth, is periodically driven at a specific frequency. Furthermore, the drive unit 200 drives the power transmission unit 400 at a specific speed in order to drive the power transmission unit 400 at a specific frequency. In other words, if the motor unit 210 drives at a specific RPM, then the power transmission unit 400 can be driven at a specific frequency, and this can be defined as the movable hanger 100 being driven at a specific frequency.

[0343] If the movable hanger 100 starts to drive at a low frequency, the long garment L reciprocates along the power transmission section 400. During this process, the upper end of the garment L moves together with the power transmission section 400, but as it moves away from the power transmission section 400, inertial forces act on the garment L, causing it to remain stationary. As a result, the garment moves from top to bottom with a lag compared to the upper end, thus the lower end of the garment L moves with the most lag among all garments.

[0344] Furthermore, when the power transmission unit 400 stops to change the direction of movement, the upper end of the garment L stops along with the power transmission unit 400, but the lower end of the garment tends to remain in motion due to inertia. As a result, the garment moves further than the power transmission unit 400 as it moves from top to bottom, and the lower end of the garment moves even more.

[0345] If the frequency of the movable hanger 100 is low and the power transmission unit 400 reciprocates at a relatively low speed, the amplitude of the reciprocating movement of the lower end of the garment is greater than the amplitude of the reciprocating movement of the upper end of the garment.

[0346] In this situation, if the frequency of the movable hanger 100 becomes higher, the power transmission unit 400 will reciprocate faster than before, and the magnitude of the inertial force generated by the garment L will be greater. As a result, the displacement difference between the lower end and the upper end of the garment may become larger.

[0347] Additionally, if the power transmission unit 400 is shaken by clothing, the movable hanger 100 will bear an extra load. This load is maximized when the power transmission unit 400 changes direction of movement.

[0348] Reference Figure 12 (c) If the movable hanger 100 is driven at a faster frequency, the reciprocating speed of the power transmission unit 400 becomes faster. At this time, the displacement difference between the upper and lower parts of the garment may even change the direction of movement of the upper and lower parts of the garment.

[0349] Furthermore, as the garment moves from the upper part to the lower part, the displacement difference gradually increases. If this displacement matches the reciprocating movement of the power transmission unit 400, the garment generates various intervals that vibrate in different directions as it moves from the upper part to the lower part, and the garment forms a waveform and vibrates.

[0350] If the clothing vibrates, the vibration energy is transmitted to the movable hanger 100, becoming an additional load applied to the drive unit 200.

[0351] Furthermore, if the movable hanger 100 is driven at a faster frequency, the garment forms more waveforms and vibrates. As a result, the garment L does not move in the same direction as a whole, but moves in different directions from top to bottom, thereby causing the garment to vibrate as a whole.

[0352] In other words, if the drive unit 200 accelerates from a low speed and drives at a speed above a certain level, the garment L as a whole will not vibrate in the same direction, but rather in different directions. As a result, the garment can form a wave pattern along the height direction and fold back.

[0353] The folding of the garment L can be defined as the state in which the garment L produces positions with different amplitude directions.

[0354] If the drive unit 200 is driven at a speed greater than the speed at which the garment L folds back, the garment L will form a region of nodal n that does not vibrate at least momentarily relative to the movable hanger 100 and a region of antinode a that vibrates to the maximum in the direction of movement or the opposite direction relative to the movable hanger 100.

[0355] If the power transmission unit 400 reciprocates more rapidly, more nodes n and antinodes a will be formed on the garment L.

[0356] In addition, if the movable hanger 100 is driven at the same frequency as the resonant frequency of the clothing, the clothing L can form a standing wave and vibrate or fold back.

[0357] The vibration of the clothing as a standing wave means that the vibration of the clothing is such that the position of the seemingly stationary node n on the clothing does not change with the passage of time, and the position of the antinode a on the clothing vibrating with maximum amplitude also does not change with the passage of time.

[0358] The standing wave is generated whenever the movable hanger 100 is driven at n times the resonant frequency. As a result, whenever the drive unit 200 reaches a specific speed range, the garment vibrates with a standing wave, and the positions of the regions where the nodes n and the antinodes a are formed on the garment do not change.

[0359] The vibrations generated in the clothing cancel each other out when their amplitude directions are different, thus preventing them from being fully transmitted to the movable hanger 100. If the clothing vibrates as a standing wave, the vibration patterns generated by the clothing can be symmetrically formed along the height direction of the clothing. As a result, if the clothing vibrates as a standing wave, most of the vibrations generated by the clothing may be canceled out, minimizing the vibration transmitted to the movable hanger 100.

[0360] Figure 13It is a graph showing the changes in the vibration pattern of clothing based on the driving frequency of the movable hanger.

[0361] Reference Figure 13 (a) When the movable hanger 100 is driven at a frequency below the fundamental frequency, the garment L as a whole can move in the same direction. When the movable hanger 100 is driven at the fundamental frequency, the garment L can move in the same direction only by varying the amplitude of each region.

[0362] The fundamental frequency can be defined as the driving frequency of the movable hanger 100 at which the waveform or vibration begins to be generated on the clothing.

[0363] If the movable hanger 100 is driven below the fundamental frequency, no waveform is generated on the garment, so the entire garment can move in the same direction.

[0364] The first speed, which is the speed at which the drive unit 200 is driven, can be defined as the speed at which the movable hanger 100 is driven at a fundamental frequency. When the drive unit 200 is driven from a stationary state to a first speed at which the garment L can begin to fold back, the overall direction of movement of the garment L can be the same.

[0365] In other words, the amplitude of the upper end of the garment and the amplitude of the lower end of the garment may be different, but the moving direction of the power transmission unit 400 and the moving direction of the garment as a whole may be the same.

[0366] Reference Figure 13 (b) If the movable hanger 100 is driven at a frequency higher than the fundamental frequency, the garment L may fold back. Additionally, if the movable hanger 100 is driven at a resonant frequency faster than the fundamental frequency, the garment L may vibrate as a standing wave.

[0367] Whenever the minimum resonant frequency is n times the minimum resonant frequency, the garment can form a standing wave and vibrate. Therefore, the minimum resonant frequency can be defined as the minimum frequency at which the movable hanger 100 enables the garment to initially vibrate at the standing wave.

[0368] The driving speed of the drive unit 200 when the movable hanger 100 is driven at the minimum resonant frequency can be defined as the second speed. The second speed can be set to be faster than the first speed. The second speed can be defined as the minimum resonant speed.

[0369] If the drive unit 200 is driven at a speed greater than a first speed, the garment L may fold back. As a result, the garment L may form a region where the direction of vibration changes along the height direction.

[0370] If the drive unit 200 is driven at the second speed, the reciprocating cycle of the movable hanger 100 can correspond to the reciprocal of the resonant frequency of the garment L, and the garment L can vibrate as a standing wave.

[0371] If the garment L vibrates as a standing wave, then the position of the node n, which is a region without vibration in the garment L, is fixed, and the position of the antinode a, which is a region with the maximum amplitude, is also fixed.

[0372] If the drive unit 200 is driven at a second speed and a first standing wave is generated on the garment L, then one node n can be formed, and one more antinode a can be formed because it includes the upper end of the garment.

[0373] In other words, if the drive unit 200 is driven at a second speed, the clothing can be shaken at a first resonant frequency f1 and vibrate with a first (n=1) standing wave.

[0374] The resonant frequency of the standing wave vibration of the garment L can be determined as an inherent characteristic of each garment.

[0375] Equation (1)

[0376] Equation (1) represents the resonant frequency of the movable hanger 100 that enables the garment L to form a standing wave and vibrate.

[0377] The resonant frequency f is equivalent to the vibration period T of the movable hanger 100 or the reciprocating period T.

[0378] In equation (1), v is related to the tension and linear density of the garment and can be determined by the fiber characteristics of each garment, and l represents the length of the garment.

[0379] As a result, the resonant frequency f of the standing wave generated by the garment L is set to vary depending on the length l of the garment, decreasing as the length l of the garment increases.

[0380] Reference Figure 13 (c) The movable gantry 100 can be driven at a frequency higher than twice the minimum resonant frequency.

[0381] As a result, the driving speed of the drive unit 200 is doubled, thereby reducing the vibration period of the power transmission unit 400 by half. Consequently, the clothing can form a standing wave and vibrate at f2, which is equivalent to twice the first resonant frequency.

[0382] The driving speed of the drive unit 200 when the movable hanger 100 is driven at twice the minimum resonant frequency (n=2) can be defined as the third speed.

[0383] That is, the garment L can vibrate in the form of a second standing wave (n=2) with two nodes n and three antinodes a.

[0384] When the garment L vibrates with a second standing wave (n=2), the positions of the nodes n and the antinodes a are formed to be different from the positions of the nodes n and the antinodes a when the garment L vibrates with a first standing wave (n=1).

[0385] Therefore, if the frequency driven by the movable hanger 100 is determined to be a multiple of the resonant frequency, it can be controlled to change in the region where the clothing generates the maximum amplitude.

[0386] Utilizing this, the garment handling apparatus of the present invention can concentrate the energy generated by the movable hanger 100 onto a specific area of ​​the garment. Furthermore, the movable hanger 100 can change the frequency to alter and concentrate the vibration of a specific area of ​​the garment. Therefore, the garment handling apparatus of the present invention can more effectively shake off dust or foreign objects adhering to the garment.

[0387] Reference Figure 13 (d) The movable gantry 100 can be driven at a frequency three times higher than the minimum resonant frequency.

[0388] The driving speed of the drive unit when the movable hanger 100 is driven at three times the minimum resonant frequency can be defined as the fourth speed.

[0389] The speed of the drive unit 200 can be driven at a speed three times that of the second speed when the clothing vibrates with the first standing wave, and the cycle of the power transmission unit 400 is shortened to 1 / 3.

[0390] As a result, the garment vibrates at a resonant frequency f3, forming a third standing wave (n=3) and vibrating, thereby creating three nodes n and four antinodes a within the garment L. The positions of the nodes n and antinodes a when the garment L vibrates with the third standing wave (n=3) are different from those when the garment L vibrates with the first standing wave (n=1) and the second standing wave (n=2). Furthermore, the interval between the nodes n can be narrower than before.

[0391] However, the amplitude of the antinode a can be the same as when the movable hanger 100 is driven at the minimum resonant frequency or twice the minimum resonant frequency.

[0392] The garment handling device of the present invention can set more areas of garment vibration and vibrate evenly by adjusting the frequency of the movable hanger 100, or set fewer areas of garment vibration and concentrate the vibration.

[0393] Reference Figure 13 (e) If the movable hanger 100 is driven at a speed four times the minimum resonant frequency and the drive unit 200 is driven at a speed four times the second speed when the clothing vibrates with the first standing wave, then the reciprocating cycle of the power transmission unit 400 is shortened to 1 / 4.

[0394] The driving speed of the drive unit when the movable hanger 100 is driven at four times the minimum resonant frequency can be defined as the fifth speed.

[0395] In this way, the driving speed of the driving unit 200 when the movable gantry 100 is driven at k times (n=k) the minimum resonant frequency can be defined as the k+1 speed.

[0396] As a result, the garment vibrates at a resonant frequency f4, and the garment L vibrates as a fourth standing wave (n=4). Four nodes n and five antinodes a can be formed within the garment L, and they vibrate. The positions of the nodes n and antinodes a when the garment L vibrates as a fourth standing wave (n=4) are different from those when the garment L vibrates as a first standing wave (n=1), a second standing wave (n=2), and a third standing wave (n=3).

[0397] Furthermore, the interval between the nodes n can be narrower than before. If the amplitudes of the power transmission units 400 are the same, then the amplitudes of the antinodes a can be made the same.

[0398] If the drive unit 200 is driven faster, the spacing between the plurality of nodes n formed by the clothing can become narrower, and the positions of the plurality of nodes n can also be changed.

[0399] As described above, if the movable hanger 100 vibrates at n times the minimum resonant frequency or the drive unit 200 vibrates at n times the second velocity equivalent to the minimum resonant velocity, the garment L can vibrate in a standing wave pattern proportional to the n times.

[0400] According to equation (1), the resonant frequencies of the garments as standing wave vibrations are determined to be different from each other based on the length of the garments. Additionally, the driving speed or driving RPM of the driving unit 200 as a standing wave vibration can also be determined as an inherent value for each garment.

[0401] On the other hand, the garment processing device of the present invention can be configured to distinguish whether the garment vibrates randomly or forms a standing wave and vibrates.

[0402] If the driving frequency of the movable hanger 100 is increasing during the process, and this driving frequency corresponds to the resonant frequency of the suspended clothing, then the clothing will vibrate as a standing wave, and thus its vibration characteristics will be different from those before and after.

[0403] In other words, when the garment does not vibrate as a standing wave, the vibration change is linear or the amount of vibration change is predictable. However, when the garment vibrates as a standing wave, the vibration characteristics change drastically, unlike when it vibrates at the previous frequency and the subsequent frequency.

[0404] Using this, the control unit C can sense whether the frequency of the corresponding movable hanger 100 is the resonant frequency of the hanging clothes by a sharp change in the current value or power value output from or applied to the motor unit 210 of the drive unit 200.

[0405] For example, when the clothing vibrates at a resonant frequency, the current or electrical value sensed in the drive unit 200 may momentarily have a peak value.

[0406] Alternatively, compared to when the garment vibrates as a standing wave, the vibration can be attenuated more when the garment vibrates as a standing wave, and less vibration can be transmitted to the movable hanger 100. Therefore, the control unit C can sense the resonant frequency of the suspended garment by a sharp decrease in the load applied to the drive unit 200.

[0407] Alternatively, the control unit C can be... Figure 13 The control unit C senses whether the frequency of the movable hanger 100 corresponds to the resonant frequency of the clothing by means of the method described herein. The control unit C can sense in real time whether the clothing vibrates at the resonant frequency by analyzing the characteristics of the second harmonic in electrical information including the current or power value of the drive unit 200. For example, by observing the characteristic of a sharp change in at least one of the waveform, amplitude, and period of the second harmonic, the control unit C can sense that the frequency of the corresponding movable hanger 100 is the resonant frequency of the suspended clothing.

[0408] Furthermore, the control unit C can sense whether the garment is vibrating at a resonant frequency by monitoring the change in the driving speed of the drive unit 200 when the garment vibrates at a resonant frequency. For example, the control unit C can determine the resonant frequency of the garment by sensing the instantaneous change in the driving speed of the drive unit 200 when the garment vibrates at a resonant frequency and when the garment vibrates at a frequency different from the resonant frequency.

[0409] In addition, the control unit C can sense the resonant frequency by instantaneously changing the inertial force transmitted to the movable hanger 100 when vibrating at the resonant frequency.

[0410] Furthermore, even if the actual garment does not vibrate at the resonant frequency, the control unit C can immediately estimate the resonant frequency of the corresponding garment by matching the second harmonic output from the drive unit 200 when the corresponding garment vibrates with a pre-stored table or data.

[0411] Furthermore, the control unit c can determine whether the sensed resonant frequency corresponds to the actual resonant frequency. For example, when the control unit c drives the movable hanger 100 at a frequency that corresponds to a multiple of the sensed resonant frequency, it can confirm whether the changes sensed by the aforementioned method are periodic.

[0412] As a result, the control unit C can calculate and sense at least one of the following: the resonant frequency of the garment, the driving speed of the drive unit 200 used to make the garment vibrate at the resonant frequency, the RPM of the drive unit 200, and the reciprocating cycle of the power transmission unit 400, through the movable hanger 100.

[0413] The following describes an embodiment of the control method of the garment handling apparatus of the present invention, which uses the vibration characteristics of the garment to accurately sense the weight of the garment.

[0414] On the other hand, if the garment L vibrates and forms a node n on the garment, the vibration generated at a position lower than the node n may not be completely transmitted to the movable hanger 100.

[0415] Furthermore, if the garment L vibrates with a standing wave, the position of the node n is always fixed. Therefore, the vibration generated by the garment L is blocked by the node n and cannot be completely transmitted to the movable hanger 100.

[0416] In addition, as the garment L vibrates with a standing wave L of a greater multiple, the interval between the nodes n becomes shorter, thus reducing the total vibrational energy of the garment remaining between the nodes.

[0417] As a result, as the garment vibrates with a larger standing wave, the node closest to the movable hanger 100 is also closer to the movable hanger 100, thus less vibration or inertial force is transmitted to the movable hanger 100.

[0418] In summary, even if the weight of the garments is the same, the vibrational energy or inertial force transmitted from the garment L to the movable hanger 100 varies depending on the position of the node n generated in the garment L, the interval between the movable hanger 100 and the adjacent node n, and whether the garment L vibrates with a standing wave or an arbitrary waveform.

[0419] The garment handling apparatus of the present invention can approximately sense the weight of the garments suspended on the movable hanger 100 by measuring the current value generated in the drive unit 200 when the movable hanger 100 is driven. Furthermore, the garment handling apparatus of the present invention can accurately correct and calculate the weight of the garments suspended on the movable hanger 100 by comprehensively sensing the vibration characteristics of the garments according to the drive speed of the drive unit 200, sensing the resonant frequency generated by the garments, and the changes in the vibration characteristics of the garments when the drive speed of the drive unit 200 is changed, etc.

[0420] The following describes one embodiment of the garment handling apparatus of the present invention for sensing the weight of garments. However, this is only one embodiment, and the garment handling apparatus of the present invention can drive the drive unit 200 at any speed to sense the weight of garments by the aforementioned method.

[0421] Of course, in order to minimize the vibration characteristics of the garment when the weight of the garment is sensed by driving the movable hanger 100, the garment handling apparatus of the present invention can be operated in the speed range that minimizes the vibration generated by the garment.

[0422] Therefore, the garment handling apparatus of the present invention can be configured to calculate the weight of the garment by driving the movable hanger 100 at a frequency lower than the resonant frequency at which a standing wave is generated on the garment.

[0423] In addition, the garment handling apparatus of the present invention can be configured to calculate the weight of the garment by driving the movable hanger 100 at a lower frequency (period) than the fundamental frequency (cycle) at which the waveform or vibration begins to be generated on the garment.

[0424] That is, the garment handling apparatus of the present invention can be configured to drive the drive unit 200 in a region where the garment vibrates at a speed below the standing wave speed when calculating the weight of the garment suspended on the movable hanger 100.

[0425] The garment handling apparatus of the present invention can calculate the weight of the garment by driving the drive unit 200 at a speed range below a second speed which is the minimum resonant speed.

[0426] Specifically, the control unit C of the garment handling apparatus of the present invention can sense the weight of the garment by applying electrical information to the drive unit 200 or outputting electrical information from the drive unit 200 when the drive frequency of the movable hanger 100 increases from the stationary speed of the movable hanger 100 to the second speed.

[0427] In addition, in order to minimize the impact of the vibration of the clothing on the drive unit 200 and eliminate the influence of the nodes n generated when the clothing folds back and vibrates, the control unit C can drive the drive unit 200 in a range below the first speed and sense the weight of the clothing.

[0428] That is, the control unit c can eliminate the influence of the clothing vibration on the drive unit 200 by driving the movable hanger 100 at a speed range below the speed at which the clothing is about to fold back, thereby enabling the weight of the clothing to be calculated by analyzing the load applied to the drive unit 200.

[0429] The control unit c calculates the weight of the clothes by driving the drive unit 200, which can directly adopt the method of using a motor to rotate the drum in existing washing machines and dryers.

[0430] As a result, the garment handling apparatus of the present invention can accurately sense the weight of the garment. Furthermore, the garment handling apparatus of the present invention can drive the mechanical chamber after sensing the weight of the garment to supply the garment with steam or hot air. That is, depending on the sensed weight of the garment, one or more of the steam and hot air supplied to the garment can be set differently, and the driving frequency of the movable hanger 100 can also be controlled differently.

[0431] For example, when sensing the weight of the garment, the garment handling apparatus of the present invention drives the movable hanger 100 at a frequency below the basic frequency, but when executing any procedure for handling the garment, it can drive the movable hanger 100 at a frequency greater than the basic frequency. Therefore, the garment handling apparatus of the present invention transmits more physical force to the garment when handling it, thereby enabling it to shake off more foreign objects from the garment or to expose the garment more evenly to the supplied steam and hot air.

[0432] The garment handling apparatus of the present invention can determine the maximum frequency of driving the movable hanger 100 according to the weight of the garment. The garment handling apparatus of the present invention can be controlled such that, when one or more of the steam and the hot air are supplied to the inner housing 20, the maximum frequency of driving the movable hanger 100 varies according to the weight of the garment.

[0433] For example, even if the movable hanger 100 is driven at the same frequency, more vibrations can be generated as the weight of the garment increases. Therefore, the maximum frequency at which the movable hanger 100 is driven can be set to decrease as the weight of the garment increases.

[0434] For example, the heavier the garment, the more hot air or steam needs to be supplied to complete the drying, deodorizing, sterilizing, and dehumidifying processes. Therefore, the garment processing apparatus of the present invention can control the steam generator 50 to supply a larger volume of steam or a longer duration of steam injection to the inner housing when the garment is heavier than when it is sensed to be lighter. Furthermore, the garment processing apparatus of the present invention can control the compressor 83 and the blower fan to supply a larger volume of hot air or a longer duration of hot air supply when the garment is heavier than when it is lighter.

[0435] Figure 14 This is used to explain the principle by which the garment handling apparatus of the present invention can sense the length of the garment.

[0436] Figure 14 (a) shows that when a long garment L is suspended from the movable hanger 100, the drive unit 200 is driven at a specific speed greater than the second speed V2. Figure 21 (b) shows that when a garment l shorter than the long garment L is suspended from the movable hanger 100, it is driven at the same specific speed as when the long garment L is suspended from the movable hanger 100.

[0437] According to equation (1), the resonant frequency is inversely proportional to the length of the garment. Therefore, the short garment l has a larger resonant frequency than the long garment L. Only when the moving hanger 100 is driven at a faster speed can a standing wave of the same order be formed on the short garment l.

[0438] Reference Figure 14 (a) The specific velocity can be equivalent to four times the second velocity or the minimum resonant velocity based on the long garment L. Therefore, the long garment L can form the fourth standing wave and vibrate.

[0439] Reference Figure 14 (b) When the short garment l is being hung, the drive unit 200 can also be driven at the same speed. In other words, Figure 21 In (b), the drive unit 200 can also be driven at a drive speed that can form a fourth standing wave in the long garment L.

[0440] In the case of short garment l, the driving speed can be equivalent to the driving speed at which the second standing wave is formed on the short garment. That is, in the case of short garment l, since the length of the garment is longer than that of long garment L, it has a different resonant frequency than that of long garment L.

[0441] The garment handling apparatus of the present invention can also utilize the property that the garment has different resonant frequencies according to its length to drive the movable hanger 100 to sense the length of the garment.

[0442] --(1)

[0443] Referring to the aforementioned equation (1), the resonant frequency fn of the standing wave vibration of the garment is inversely proportional to the length of the garment. However, there is a limitation that even if the resonant frequency fn is known, the length l of the garment cannot be accurately sensed if the value of v in equation (1) is not known precisely.

[0444] ----(2)

[0445] Referring to the above formula (2), v corresponds to the square root of the value of the tension T of the garment divided by the linear density m, and the tension of the garment is equivalent to the weight of the garment.

[0446] The linear density m is equivalent to a constant value under the same clothing conditions. Therefore, if the control unit c senses the weight of the clothing and the resonant frequency fn, it can determine the length l of the clothing.

[0447] Therefore, in the weight sensing step A1, the control unit c directly calculates the weight of the garment using the electrical information of the drive unit 200. In the length sensing step A2, it can change the drive speed of the drive unit 200 and sense one or more resonant frequencies that can cause the garment to vibrate with a standing wave, and calculate the length of the garment using the weight of the garment and the resonant frequencies.

[0448] Even when the control unit c cannot specifically sense or calculate the linear density m, the control unit c can still calculate the length l of the garment by sensing two or more resonant frequencies that can cause the garment to vibrate with a standing wave.

[0449] In addition, the control unit c can sense the resonant frequency that enables the garment to vibrate with a standing wave through the movable hanger 100, and calculate the length l of the garment by the electrical information output from the drive unit 200 when the drive frequency of the movable hanger 100 is changed.

[0450] As a result, the control unit c can calculate the weight of the garment by driving the drive unit 200 at a speed range lower than the second speed v2 that enables the garment to initially vibrate at the resonant frequency, and can calculate the length of the garment by driving the drive unit 200 at a speed range higher than the second speed that enables the garment to initially vibrate at the resonant frequency.

[0451] The speed range less than the second speed may include the first speed, and in the drive range s, the drive unit 200 may drive at a speed faster than the second speed.

[0452] Figure 15 This is a diagram illustrating an embodiment of the mobile gantry of the present invention with variable system states.

[0453] As mentioned above, the clothes suspended on the movable hanger 100 can hang down in the height direction without clumping inside the drum. Only one side of the clothes is suspended on the movable hanger 100. Therefore, in order to use the drive of the movable hanger 100 to sense the weight and length of the clothes, it is necessary to consider the vibration characteristics of the clothes and their changes based on the drive frequency of the movable hanger 100.

[0454] However, the system constituting the movable hanger 100 of the present invention not only changes periodically when the movable hanger 100 is driven, but the characteristics of the components constituting the movable hanger 100 can also change. Therefore, in order to use the drive of the movable hanger 100 to sense the weight and length of the clothing, it is also necessary to take into account the system variation characteristics of the movable hanger 100.

[0455] For example, refer to Figure 6 The movable hanger 100 of the present invention indirectly transmits the power of the motor 210 through the combination of the belt component and the pulley, instead of directly transmitting it to the displacement generation unit 300 and the power transmission unit 400.

[0456] In other words, the rotating shaft 221 of the motor 210 always rotates at the exact position regardless of the driving speed. However, since the drive pulley 231 and the transmission pulley 232 rotate independently with respect to the two axes of the rotating shaft 211 and the power shaft 240 and are coupled and rotated by the belt member 233, the system characteristics can change as the belt member 233 rotates.

[0457] Reference Figure 15 In (a), the belt member 233 contacts the outer peripheral surfaces of the drive pulley 231 and the transmission pulley 232, and the thickness of the belt member 233 is thinner than the thickness of the drive pulley 231 and the transmission pulley 232.

[0458] Alternatively, at least one of the drive pulley 231 and the transmission pulley 232 can be made thicker than the belt member 233, thereby preventing the belt member 233 from detaching from the drive pulley 231 and the transmission pulley 232.

[0459] Furthermore, at least one of the drive pulley 231 and the transmission pulley 232 can be configured to be thicker than the belt member 233, so that the entire thickness direction of the belt member 233 is in surface contact with the drive pulley 231 and the transmission pulley 232. Thus, the power of the motor 210 can be transmitted with maximum losslessness.

[0460] On the other hand, the drive pulley 231 and the transmission pulley 232 are coupled to the inner circumferential surface of the belt member 233 to provide tension to the belt member 233. In this condition, the belt member 233 has an upward and downward movement interval in one or more of the drive pulley 231 and the transmission pulley 232, so that periodic tension changes of the belt member 233 can be generated when the drive pulley 231 and the transmission pulley 232 rotate.

[0461] As a result, if the drive pulley 231 and the transmission pulley 232 rotate, the belt member 233 can rotate and move together with the drive pulley 231 and the transmission pulley 232, and can reciprocate between the upper and lower parts of the outer peripheral surface of at least one of the drive pulley 231 and the transmission pulley 232.

[0462] Specifically, refer to Figure 15 (a) to Figure 15 (e) Even if the belt member 233 starts rotating from the center of the transfer pulley 232, it can move to the upper part of the transfer pulley 232 and descend to the center again, and then move to the lower part of the transfer pulley 232 and rise to the center of the transfer pulley 232 again.

[0463] As a result, the belt member 233 rotates and periodically moves in four regions: the upper region, the central region, the lower region, and the central region of the transmission pulley 232. Therefore, the conversion unit 230 has a drive cycle that is four times that of the moving hanger 100.

[0464] Since the driving cycle is formed longer and slower than the reciprocating cycle of the moving hanger or the vibration cycle of the clothing, it can be defined as a low-frequency cycle.

[0465] The low-frequency cycle of the conversion unit 230 also affects the load on the motor 210. Therefore, the power transmitted from the motor 210 to the clothing can also be transmitted according to the low-frequency cycle.

[0466] Figure 16 This is a graph showing the characteristic of the movable hanger according to the invention as a function of the vibration cycle generated by the movable hanger.

[0467] Reference Figure 16The diagram shows the high-order harmonic variations of the mobile hanger 100 as it reciprocates over 25 cycles when the same 1.2kg of clothing is suspended on the mobile hanger 100, but when clothing of various materials such as jackets, wool coats, suits, dresses, and shirts are suspended from the upper end of the diagram downwards. These variations are sensed in the drive unit 200.

[0468] If the system of the movable hanger 100 remains unchanged, it is expected that the amplitude of the higher harmonics generated by each garment in each cycle of the movable hanger 100 may be different, but the amplitude of the higher harmonics does not change or the change is based on the one-cycle movement of the movable hanger 100.

[0469] However, it can be confirmed that, regardless of the material of the clothing, the magnitude of the higher harmonics of all clothing continuously changes as the moving hanger 100 moves to 16 cycles, and then the waveform of the higher harmonics repeats the same waveform for 1 cycle.

[0470] In other words, it means that the maximum amplitude generated by the clothing is not a driving cycle of the moving hanger 100, but changes periodically at each specific time.

[0471] Therefore, it is known that in order to sense the state of clothing, it is necessary to consider the changes in high-order harmonics caused by the movable hanger 100 system, and to comprehensively grasp that the current value of the drive unit 200 is equivalent to more than one cycle of the high-order harmonics of the movable hanger 100 system, in order to correct and obtain accurate information about the weight, length, and material of the clothing.

[0472] Figure 17 It is a diagram showing the state of periodic changes in the position of the belt components as the belt components change.

[0473] The high-order harmonic characteristics of this movable gantry 100 system are generated by the belt member 233, and therefore can vary according to the tension of the belt member 233.

[0474] For example, Figure 17 Compared to Figure 15 The movable hanger only has its tension set to be greater for the components; all other structures, sizes, and lengths can be the same.

[0475] When the tension of the belt member 233 increases, the movement of the belt member 233 along the thickness direction of the drive pulley 231 and the transmission pulley 232 can slow down. In other words, if the tension of the belt member 233 increases, the friction between the belt member 233 and the outer peripheral surfaces of the drive pulley 231 and the transmission pulley 232 becomes greater, so the belt member 233 can move more slowly along the thickness direction of the drive pulley 231 and the transmission pulley 232.

[0476] For example, if in Figure 15 In the process, when the transfer pulley 232 rotates 4 revolutions, the belt component 233 reciprocates between the upper and lower ends of the transfer pulley 232 and returns to its initial position. Therefore, in... Figure 17 It can be confirmed that the belt component 233 only reciprocates between the upper and lower ends of the transmission belt pulley 232 after the drive pulley rotates 8 times.

[0477] like Figure 15 As shown, when the tension is weak, when the same pulley 232 rotates one revolution, the belt member 233 can rise directly from the center of the pulley 232 to the top, while... Figure 17 As shown, under high tension, even if the same transmission pulley 232 rotates once, the belt member 233 can only rise from the center of the transmission pulley 232 to half the height of the upper end.

[0478] Furthermore, as the tension of the belt member 233 increases, the belt member 233 needs to transmit more rotations of the pulley 232 as it reciprocates from the upper end to the lower end of the transmission pulley 232.

[0479] As a result, it can be seen that, due to the combination of the belt member 233 and the pulley, the mobile gantry 100 system of the present invention has a higher harmonic period T corresponding to four times the length and tension of the belt member.

[0480] On the other hand, even Figure 15 and Figure 17 As the tension of the belt member 233 changes, the cycle of the belt member 233 reciprocating from the upper end to the lower end of the belt member 233 will also become faster as long as the transmission pulley 232 rotates at high speed. Therefore, it can be seen that the movable hanger 100 system has a high-order harmonic 1-cycle T that is inversely proportional to the driving speed of the motor 200.

[0481] As a result, when the movable hanger 100 is driven, the self-generated higher harmonic (Tave) of the movable hanger 100 is proportional to four times the tension of the belt member 233 and inversely proportional to the rotational speed of the motor 210.

[0482] On the other hand, the characteristics of the higher harmonic period (hereinafter, system period) of the system can also be described in different ways.

[0483] In the mobile gantry 100 system, when the mobile gantry 100 is driven, the system cycle (Tave) generated by the mobile gantry 100 itself can be summarized as follows.

[0484]

[0485] Here, n is a factor related to the tension of the belt member, corresponding to a natural number; LB is the length of the belt member; D2 corresponds to the diameter of the transmission pulley 232; and w corresponds to the various speeds of the motor 210.

[0486] Reference Figure 6 If the distance L between the center of the drive pulley 231 and the transmission pulley 232 increases, the length of the belt member 233 also increases. The length of the free length LB of the belt member 233 that is not currently in contact with the drive pulley 231 and the transmission pulley 232 but can contact the transmission pulley 232 can also increase.

[0487] Currently, the system frequency of the moving hanger 100 is generated when the region corresponding to the free length LB of the belt member comes into contact with one of the transmission pulley 232 and the fixed pulley 231 in a reciprocating motion.

[0488] The period corresponding to the free length LB will begin to continuously contact the transmission pulley 232 and return to the initial position from the transmission pulley 232 can be set to the least common multiple of the reciprocating motion of the upper and lower ends of the drive pulley 231 and the upper and lower ends of the transmission pulley 232, i.e., four times. The free length LB can be defined as: √(C^2 + ((D2-D1) / 2)^2). C corresponds to the straight-line distance between the power shaft 240 and the motor shaft 221.

[0489] Therefore, it can be confirmed that the system cycle is directly proportional to four times the length of the belt component and inversely proportional to the rotation axis of the motor 210.

[0490] Figure 18 This is a diagram illustrating the control method of the garment handling apparatus of the present invention, which senses the state of the garment by moving a hanging bracket.

[0491] As a result, in order to grasp the status information of the clothes using the movable hanger 100, the garment handling apparatus of the present invention needs to sense the system cycle of the movable hanger and the vibration characteristics of the clothes driven by the movable hanger 100.

[0492] Therefore, the garment handling apparatus of the present invention can first perform the system sensing step S1 of the system cycle of sensing the moving hanger 100.

[0493] That is, only after confirming the system cycle of the movable hanger 100 can the weight and length be accurately sensed by the resonant frequency of the movable hanger 100 or the current value of the motor 210 during periods above that cycle.

[0494] In the system sensing step S1, the system cycle T needs to be executed at least once when driving the mobile gantry 100 in order to grasp the system cycle T.

[0495] The clothing sensing step S2, which begins sensing the state of the clothing, can be executed.

[0496] The clothing sensing step S2 can correspond to keeping the driving speed of the movable hanger 100 constant for a certain period of time and sensing the weight of the clothing.

[0497] In the clothing sensing step S2, after understanding the vibration characteristics of the clothing, the current value of the drive unit 200 needs to be collected for more than the system period T in order to accurately sense the state of the clothing.

[0498] The clothing sensing step S2 can be executed when the system sensing step S1 is completed, or it can be executed simultaneously during the system sensing step S1.

[0499] That is, the system cycle T can be determined when the system sensing step S1 is executed. If the system cycle T has been determined, the state of the clothing can be calculated by calculating the current value of the motor 210 corresponding to the corresponding system cycle T.

[0500] However, if the system sensing step S1 and the clothing sensing step S2 are performed at the same motor drive speed, the length of the clothing cannot be sensed.

[0501] Therefore, the clothing sensing step S2 can be understood as the step of sensing the weight of the clothing.

[0502] The garment handling apparatus of the present invention can perform an additional sensing step S3, which drives the motor 210 at a constant speed for a predetermined time, different from the driving speed of the motor in the garment sensing step S2. Through the additional sensing step S3, the current value information of the motor 210 can be confirmed in two speed regions, and thus one or more of the length and material of the garment can be calculated.

[0503] In the additional sensing step S3, in order to sense the length or material of the clothing, it is necessary to collect the current value of the motor 210 for a period of more than T.

[0504] However, if the drive speed of the motor 210 changes in the additional sensing step S3, the sensing time of the additional sensing step S3 can also change. This is because the system period T varies according to the drive speed. For example, if the drive speed of the motor 210 in the additional sensing step S3 is faster than in the clothing sensing step S2 or the status sensing step S1, the sensing time of the additional sensing step S3 can be shorter than the sensing time of the clothing sensing step S2 or the status sensing step S1. As a result, the additional sensing step S3 can be executed faster than the clothing sensing step S2 or the status sensing step S1.

[0505] If the additional sensing step S3 also ends, the control unit of the garment handling device of the present invention can not only acquire the system of the movable hanger 100, but also acquire more than one of the garment information, such as the weight, length, and material of the garment.

[0506] Therefore, based on the obtained information, an acceleration drive step S4 can be performed to increase the drive frequency of the movable hanger 100 in order to optimally shake the clothing.

[0507] The acceleration driving step S4 can correspond to the step of officially shaking off the dust from the clothes when one or more of hot air and steam are supplied.

[0508] Hot air and steam may be supplied before the acceleration drive step S4, but they may not be supplied.

[0509] The sensing time may include the sensing time of the state sensing step, the clothing sensing step, and the initial sensing step, and can be defined as the time after the moving hanger is driven and before the acceleration driving step driven at the processing speed.

[0510] Figure 19 This is a diagram illustrating one embodiment of the system cycle of the garment handling apparatus of the present invention sensing the movable hanger.

[0511] In the state sensing step S1, in order to confirm the system cycle T of the movable hanger 100, the clothing handling device of the present invention needs to rotate the drive unit 210 for a longer time than the cycle T.

[0512] The garment handling apparatus of the present invention can also calculate the system period T by sensing the low-frequency amplitude change in the drive unit 200 after driving the movable hanger 100 for a long time.

[0513] However, this may be relatively delayed, so it is necessary not to drive the mobile gantry 100 for more than one system cycle T, and complete the state sensing step S1 within one system cycle T.

[0514] Therefore, the garment handling apparatus of the present invention can sense the low-frequency amplitude generated by the movable hanger 100 at any time. For example, the low-frequency amplitude can be sensed during each cycle of the movable hanger 100's operation.

[0515] For example, if the initial sensing time point is set as X1, then the sensing time point after 1 cycle corresponds to X2, and the sensing time point after 11 cycles corresponds to X11.

[0516] Therefore, the low-frequency amplitude can be sensed in each cycle of the movable hanger 100 reciprocating and returning to its initial position. This can be tracked, and the cycle of the movable hanger 100 can be sensed by repeatedly sensing the highs and lows, or specific points and specific points of the amplitude.

[0517] Figure 20 This is a diagram illustrating a control method of the garment handling apparatus of the present invention for sensing whether a change has occurred in the system of a moving hanger.

[0518] The state sensing step S1 can be executed only once and then omitted. This is because the system of the movable hanger 100 is a factor that is not easily changed once it is determined. Therefore, in the garment handling apparatus of the present invention, if the state sensing step S1 is executed once and the history is stored, the state sensing step S1 can be omitted for a constant period or until a user requests it.

[0519] However, when there is a user request or the moving hanger 100 is driven to its limit number of times, or at each set time such as seasonal change, the clothing handling device of the present invention can perform the state sensing step S1 to check whether the tension of the belt member 233 has changed, whether the belt member 233 has been replaced, or whether the friction force is the same when the plurality of pulleys rotate, etc., whether the system of the moving hanger 100 has changed.

[0520] For example, the tension of the belt member 233 can vary depending on humidity and temperature, or it can vary depending on the aging of the belt member 233. If the belt member 233 is replaced, the change can be detected in the change sensing step.

[0521] The change sensing step can be immediately determined by whether the system period T obtained in the state sensing step S1 is the same as the system period T stored before that.

[0522] Therefore, compared to the state sensing step S1, in order to sense the system period T, the change sensing step can determine the difference in the system period T more quickly.

[0523] For example, the change sensing step may include a driving step S11 in which the rotating shaft is rotated by driving motor 210.

[0524] During the execution of the driving step S11, the control unit may perform an arrival sensing step S12 to check whether the pulley 232 and belt member 233 are driven during one cycle. The driving of the pulley 232 and belt member 233 during one cycle corresponds to one reciprocating motion of the movable hanger 100. This represents a low-frequency cycle, which is a different concept from the system cycle T, which has a low-frequency maximum amplitude and varies. Therefore, the reciprocating motion cycle of the movable hanger 100 is defined as the pulley cycle.

[0525] The driving step S11 can be continuously executed during the change sensing step.

[0526] After reaching the sensing step S12, the measurement step S13, which measures the low-frequency amplitude of the moving hanger 100 system during the sensed pulley cycle, can be performed.

[0527] If the measurement step S13 is performed, then the calculation step S14 for calculating the low frequency can be performed. The calculation step S14 can be combined with... Figure 19 The method described in the text is the same, but it can be compared... Figure 19 The methods described in the text can be executed more quickly.

[0528] For example, the calculation step S13 can correspond to only knowing the low-frequency valleys or peaks. For example, if an interval where the amplitude increases and then decreases is found, or an interval where the amplitude decreases and then increases is found, the low-frequency waveform can be directly predicted to calculate the system period T, and then the low-frequency calculation step S14 can be directly terminated.

[0529] Then, the garment processing apparatus of the present invention can perform the judgment step S15 of determining whether the system cycle T is different from the previous system cycle.

[0530] Until the operation step S14 can be executed before the system cycle T passes, the judgment step S14 and the operation step S14 can be executed almost simultaneously, so until the judgment step S15 can be completed before the system cycle T passes.

[0531] If the system cycle differs from the previous one, the new system cycle T can be updated so that the system cycle value can be directly used when the state sensing step is omitted later. Furthermore, it can be used to sense the weight, length, and material of clothing based on the new system cycle T.

[0532] However, if the system period T does not change, it can be determined that the state of the movable gantry 100 is the same.

[0533] Then, the weight, length, etc. of the clothing can be sensed by driving the drive unit 200 for a period of T or more, and the drive can be stopped before driving the drive unit 200 for a period of T or more.

[0534] Therefore, users can be notified immediately by shortening the execution time of the change sensing step, and energy can also be saved.

[0535] Alternatively, when performing the state sensing step S1, the change sensing step can also be performed simultaneously with the state sensing step S1.

[0536] Due to the change sensing step, the garment handling apparatus of the present invention can accurately sense one or more of the weight, length, and material of the garment even if the humidity / temperature changes or the belt member 233 is replaced with another belt member.

[0537] For example, when the same garment is hung on the movable hanger 100, even if the humidity or temperature changes or the belt member 233 is replaced with a different belt member, the weight, length, and material of the garment can be calculated in the same way.

[0538] When displaying the clothing information, the clothing handling device of the present invention can still display the clothing information in the same way even if the humidity or temperature changes or the belt member 233 is replaced with another belt member.

[0539] However, if the type, material, or tension of the belt component 233 changes, the system period T will also change, so the time for state sensing, clothing sensing, and additional sensing can change respectively.

[0540] Figure 21 This is a graph showing the speed change of the moving hanger when the control method of the present invention is applied.

[0541] The garment handling apparatus of the present invention can perform a state sensing step S1 during a first sensing time t1 when driving the drive unit 200. The state sensing step S1 can cause the drive unit 200 to be driven at a first speed V1.

[0542] The first sensing time t1 can be set to be longer than the system period T.

[0543] The garment handling apparatus of the present invention can perform a garment sensing step during a second sensing time t2 when driving the drive unit 200. The garment sensing step S2 can be driven at a different driving speed than the state sensing step S1. For example, the garment sensing step can be performed by driving the drive unit 200 at a second speed V2 or lower.

[0544] If the clothing sensing step S2 is driven faster than the driving unit 200 in the state sensing step S1, then the second sensing time t2 can be shorter than the first sensing time t1. This takes into account the case where the system cycle T is shortened.

[0545] The clothing sensing step S2 can correspond to the weight sensing step.

[0546] The garment handling apparatus of the present invention can perform an additional sensing step S3 during the third sensing time t2 when driving the drive unit 200.

[0547] The additional sensing step S3 can cause the drive unit 200 to rotate at a third speed.

[0548] In this case, the third sensing time t3 can be shorter than the second sensing time t2. This takes into account the case where the system period T becomes faster.

[0549] The additional sensing step S3 may be a step of sensing the length of clothing.

[0550] If the additional sensing step S3 ends, then since the state of the clothing has been sensed, the accelerated driving step S4, which uses hot air and steam to shake off the dust from the clothing and care for the clothing, can be executed.

[0551] The driving speed of the driving unit 200 in the acceleration driving step S4 can be faster than that in the state sensing step S1, the clothing sensing step S2, and the additional sensing step S3. This can be defined as the processing speed.

[0552] For example, the processing speed can be set to a speed of four or higher.

[0553] However, the driving time of the acceleration driving step S4 can be set to be longer than the sensing time.

[0554] Based on the above results, in the state sensing step S1, the clothing sensing step S2, and the additional sensing step S3, the driving speed of the driving unit 200 can be set to be slower than the driving speed in the acceleration driving step S4. Therefore, the driving speed of the driving unit 200 in the state sensing step S1, the clothing sensing step S2, and the additional sensing step S3 can be defined as the sensing speed.

[0555] In this case, it can be seen that the higher the driving speed of the sensing speed, the shorter the sensing time.

[0556] Conversely, if the sensing speed decreases, the sensing time increases.

[0557] The first sensing time t1, the second sensing time t2, and the third sensing time t3 are the times for sensing the state of the clothing and the system state of the movable hanger 100, and therefore can be collectively referred to as sensing time.

[0558] On the other hand, the length of the clothing can also be sensed in the clothing sensing step S2.

[0559] This is because the clothing sensing step S2 is driven at a different speed than the state sensing step S1. In this case, the additional sensing step S3 can be omitted.

[0560] In addition, the weight of the clothing can also be sensed simultaneously in the state sensing step S1.

[0561] On the other hand, unlike the description, the state sensing step S1 can also be executed at any speed, such as the second speed or the third speed. In this case, the clothing sensing step S2 is not always executed at the second speed, but can be executed at any speed. This is because, in the state sensing step, not only the system characteristics but also the vibration characteristics of the load must be considered.

[0562] However, considering the energy efficiency of the drive unit 200, the clothing sensing step S2 is preferably performed at the same speed as the status sensing step S1.

[0563] This invention can be implemented in various forms and modifications, therefore its scope of claim is not limited to the embodiments described above. Thus, any modified embodiment that includes the constituent elements of the claims of this invention should be considered to fall within the scope of this invention.
