Description

Technical Field

[0001] The present invention relates to a clothing treatment apparatus and a control method thereof. More specifically, it relates to a clothing treatment apparatus and a control method thereof that can perform refresh operations such as sterilization, wrinkle removal, deodorization, and drying of clothing by supplying steam and hot air to the clothing. Background Art

[0002] A clothing treatment apparatus refers to an apparatus developed for washing and drying clothing at home and in laundries and removing wrinkles generated in the clothing. As classifications of clothing treatment apparatuses, there are washing machines for washing clothing, dryers for drying clothing, washing / dryers having both a laundry function and a drying function, clothing care machines for refreshing clothing, and steamers for removing wrinkles from clothing, etc.

[0003] In recent years, there has emerged a clothing treatment apparatus, which is a clothing care machine that can keep clothing fresh and clean without soaking the clothing in water and using a laundry detergent.

[0004] Among such existing clothing treatment apparatuses, there has emerged a clothing treatment apparatus that performs a refresh operation of supplying either high-temperature air (hot air) or steam to the clothing to deodorize the clothing, dry the clothing, and remove wrinkles from the clothing.

[0005] Generally, such a clothing treatment apparatus accommodates the clothing in a manner of placing it on the upper end of the clothing. Thus, the clothing treatment apparatus can arrange the clothing in the height direction so that a plurality of clothing items can be placed in the width direction.

[0006] The clothing treatment apparatus can be configured such that a structure for placing the clothing inside (hereinafter, a moving hanger) is movable. Thus, the existing clothing treatment apparatus can shake the clothing using the moving hanger when supplying hot air and steam to the clothing, and thus has an effect of being able to shake off dust and foreign substances from the clothing.

[0007] Since the moving hanger is provided at the upper end of the accommodation space of the clothing treatment apparatus to place the clothing, the degree and form of shaking of the clothing may vary depending on the driving frequency and driving speed of the moving hanger.

[0008] Thus, in order to shake the clothing in an optimal form at different time points to maximize the refresh effect, the existing clothing treatment apparatus has designed various driving methods for the moving hanger.

[0009] Figure 1 An embodiment of shaking clothing in a clothing treatment apparatus is shown. (Refer to Japanese Patent Laid-Open Publication No. 2021-016611A)

[0010] Since the greater the shaking of the clothing, the faster the foreign matter or moisture contained in the clothing can be separated, it can be considered that the mobile hanger is preferably always driven at the highest output.

[0011] However, referring to Figure 1 the left drawing in (a) below, in the case where the mobile hanger moves too fast, the exciting force generated by the mobile hanger is only transmitted to the upper end of the clothing, and the lower part of the clothing cannot follow the movement of the mobile hanger, so it may not be able to vibrate with a sufficient amplitude.

[0012] Therefore, the shaking effect of the lower part of the clothing may be weak, and the displacement difference between the upper and lower parts of the clothing becomes larger, resulting in the clothing being stretched, and there is a risk of damaging the clothing.

[0013] Thus, referring to Figure 1 the right drawing in (a) below, the mobile hanger is preferably driven at an optimal speed that enables the vibration generated by the mobile hanger to be evenly transmitted from the upper part to the lower part of the clothing.

[0014] The clothing accommodated in the clothing processing device may be in the heaviest state when water or steam is initially supplied. The inertial force of heavy clothing is large, so it may not be easily shaken by the mobile hanger.

[0015] In addition, as the hot air is supplied and the moisture in the clothing is evaporated, the weight of the clothing may gradually become lighter. The inertial force of the lighter clothing also becomes smaller, so it can be shaken by the mobile hanger relatively easily.

[0016] Therefore, it can be preferably configured to shake the mobile hanger according to the change in the inertial force of the clothing.

[0017] Referring to Figure 1 of (b) below, in the existing clothing processing device, at the initial stage when the clothing is presumed to be in the heaviest state, the driving speed of the mobile hanger is driven at the maximum speed V1-1. Considering that the clothing dries the moisture using the hot air or separates the moisture using the vibration of the mobile hanger and becomes lighter, the driving speed of the mobile hanger can be gradually reduced and driven. (V1-2, V1-3, V2)

[0018] Thus, compared with driving the mobile hanger at a predetermined speed unconditionally, it is possible to prevent damage to the clothing and at the same time evenly transmit the dust removal force to the entire clothing.

[0019] However, such existing clothing treatment devices are not configured to drive the mobile clothes hanger according to the weight, length, type, and material of the clothes. That is, the existing clothing treatment devices cannot directly sense the weight, length, material, etc. of the clothes, so they cannot control the driving speed of the mobile clothes hanger in accordance with the state of the clothes, and can only adopt a unified driving method for the mobile clothes hanger with a simple algorithm.

[0020] In other words, there are limitations in the existing clothing treatment devices, that is, although the moving form of the mobile clothes hanger varies according to the weight, length, material, etc. of the clothes, the mobile clothes hanger cannot be driven in accordance with the state of the clothes.

[0021] Figure 2 A control method of another existing clothing treatment device with a mobile clothes hanger is shown.

[0022] A clothing treatment device with a mobile clothes hanger usually supplies steam and hot air to the placed clothes to refurbish the clothes.

[0023] Specifically, the existing clothing treatment device is driven in the following steps: a preheating step C1 of preheating the steam generator; a steam step C2 of supplying steam from the steam generator; a standby step C3 of interrupting the steam supply to output the supplied steam to the clothes; a cooling step C4 of reducing the surface temperature of the clothes and the humidity of the accommodation space; and a drying step C5 of drying the clothes by driving a heater or a compressor to supply hot air to the clothes.

[0024] Generally, the existing clothing treatment device is set such that the mobile clothes hanger will not be driven to the steam step C2 unless water is put into the accommodation space to wash the clothes.

[0025] This is because there is a risk that the clothes will be damaged by blocking the steam supply port when the clothes are detached from the mobile clothes hanger during the driving of the mobile clothes hanger.

[0026] As a result, there are limitations in the existing clothing treatment devices, that is, not only is it interrupted to drive the mobile clothes hanger before hot air supply to obtain clothing information, but also it is interrupted at the root to drive the mobile clothes hanger before steam supply to obtain clothing information.

[0027] In addition, since the existing clothing treatment devices cannot directly sense the weight, length, and material of the clothes, there are fundamental limitations in that they cannot adjust the supply method and injection amount of steam suitable for the state of the clothes, and cannot adjust the supply amount and supply time of the hot air.

[0028] In addition, since the mobile clothes hanger is movably provided at the upper part of the clothes accommodation space of the clothing treatment device, there are limitations in that it is difficult to provide an additional load sensor, etc.

[0029] In addition, even if the existing clothing treatment device senses the weight of the clothing by the driving load of the moving hanger, it cannot reflect that the torsional form of the clothing changes with the speed of the moving hanger, or the vibration force changes whenever a standing wave is formed, etc. Therefore, there is a limitation in accurately sensing the weight of the clothing.

[0030] Furthermore, the existing clothing treatment device can only rely on the input of the user to obtain information related to the length and material of the clothing. Therefore, there is a fundamental limitation in being unable to consider the state of the clothing placed and renovate it in an optimal manner. Summary of the Invention

[0036] The problem to be solved by the present invention is to provide a clothing treatment device that realizes steam supply and hot air supply in an optimal manner based on one or more of the sensed weight and length of the clothing.

[0037] The problem to be solved by the present invention is to provide a clothing treatment device capable of sensing one or more of the linear density, hydrophilicity degree, material, and type of the clothing placed.

[0038] The problem to be solved by the present invention is to provide a clothing treatment device capable of changing the driving speed of the moving hanger, the steam injection, and the hot air supply mode based on one or more of the linear density, hydrophilicity degree, material, and type of the clothing placed.

[0039] Technical Solutions for Solving the Problems

[0040] The present invention can sense the weight of the clothing during the process of driving the moving hanger.

[0041] The clothing is a structure that can twist or bend as the moving hanger moves. Therefore, the vibration characteristics of the clothing are different according to the speed of the moving hanger.

[0042] If the laundry vibrates, a reaction force is applied to the moving hanger due to the inertia at the vibration part, and this acts as a load torque on the drive motor.

[0043] That is, according to variables (such as speed and laundry length) that determine the vibration characteristics of the laundry, the characteristics of the load torque measured by the motor are different. Therefore, if only the amount of laundry is to be sensed, it is necessary to maximize the exclusion of factors that affect the vibration characteristics other than the weight of the laundry.

[0044] The laundry forms a standing wave at a specific speed and vibrates in a non-standing wave form at other speeds. Such vibration characteristics vary with the length of the laundry. Therefore, in order to sense the amount of laundry, it is necessary to exclude such vibration characteristics according to length.

[0045] Therefore, the laundry processing apparatus of the present invention drives the moving hanger at a low speed so that the laundry does not twist or bend, thereby blocking the influence of variables caused by length on the vibration characteristics.

[0046] To solve the above problems, the present invention provides a laundry processing apparatus, and a control unit of the laundry processing apparatus drives the moving hanger at a frequency lower than a fundamental frequency (period) at which a waveform or vibration starts to form on the laundry and calculates the weight of the laundry.

[0047] The control unit may sense the fundamental frequency at which the laundry starts to form a waveform or vibration while driving the moving hanger.

[0048] The control unit

[0049] may drive the moving hanger in a manner of increasing the frequency from a stationary state and sense the fundamental frequency, and may drive the moving hanger at a frequency below the fundamental frequency and calculate the weight of the laundry.

[0050] When supplying one or more of the steam and the hot air to the inner casing, the control unit may drive the moving hanger at a frequency higher than the fundamental frequency.

[0051] When supplying one or more of the steam and the hot air to the inner casing, the maximum frequency at which the control unit drives the moving hanger may vary according to the weight of the laundry.

[0052] The maximum frequency for driving the moving hanger may be set to be lower as the weight of the laundry is heavier.

[0053] The control unit may drive the mechanical chamber to supply the steam or the hot air to the laundry after sensing the weight of the laundry.

[0054] If the weight of the clothing is heavier, the control unit can control the mechanical chamber to make the steam injection amount more than when the weight of the clothing is lighter or make the steam injection time longer than when the weight of the clothing is lighter.

[0055] If the weight of the clothing is heavier, the mechanical chamber can be controlled to make the hot air supply amount larger than when the weight of the clothing is lighter or make the hot air supply time longer than when the weight of the clothing is lighter.

[0056] It may further include a display unit, which is provided on at least one of the cabinet and the door, and the display unit displays the sensed weight of the clothing to the outside.

[0057] The display unit can be set to display the weight of the clothing before supplying the steam or the hot air to the accommodation space.

[0058] The display unit can be set to display one or more of the weight and length of the clothing if the power is input and the door closes the opening.

[0059] The mechanical chamber may be provided with a steam generator and a compressor. The steam generator supplies steam to the accommodation space, and the compressor pressurizes the refrigerant that exchanges heat with the air supplied to the accommodation space. The display unit can be set to display the weight of the clothing before driving the steam generator or the compressor.

[0060] The control unit can be set to drive the mobile hanger to sense the weight of the clothing and the resonance frequency at which the clothing vibrates in the form of a standing wave.

[0061] The control unit can drive the mobile hanger at a frequency lower than the fundamental frequency (period) at which a waveform or vibration starts to form on the clothing to sense the weight of the clothing, and can drive the mobile hanger faster to sense the resonance frequency.

[0062] If the control unit drives the mobile hanger at a frequency lower than the fundamental frequency to sense the weight of the clothing, it can sense and confirm the resonance frequency while changing the driving frequency of the mobile hanger.

[0063] If the control unit drives the mobile hanger at a frequency lower than the fundamental frequency to sense the weight of the clothing, it can gradually increase the driving frequency of the mobile hanger and sense and confirm the resonance frequency.

[0064] The control unit can determine the optimal frequency for driving the mobile clothes hanger according to the sensed weight of the clothes, and drive the mobile clothes hanger at a resonance frequency close to the optimal frequency in at least a part of the interval during the execution of the program.

[0065] The control unit can drive the mobile clothes hanger at a resonance frequency higher than the optimal frequency and at a resonance frequency lower than the optimal frequency in at least a part of the interval during the execution of the program.

[0066] The control unit can repeatedly drive the mobile clothes hanger at a resonance frequency higher than the optimal frequency for a preset time and at a resonance frequency lower than the optimal frequency for a preset time.

[0067] The control unit can drive the mobile clothes hanger at a resonance frequency that makes the clothes vibrate in the form of a standing wave in at least a part of the interval during the execution of the program, but drive the mobile clothes hanger at two or more resonance frequencies that make the clothes vibrate in the form of a standing wave.

[0068] The control unit can drive the mobile clothes hanger at a first resonance frequency that makes the clothes vibrate in the form of a standing wave within a first time period, and drive the mobile clothes hanger at a second resonance frequency that makes the clothes vibrate in another standing wave form within a second time period.

[0069] If the mobile clothes hanger generates vibrations above a reference value, the control unit can drive the mobile clothes hanger at a resonance frequency that makes the clothes vibrate in the form of a standing wave.

[0070] The clothes processing device of the present invention provides a control method including a sensing step and a driving step. The sensing step senses the weight and length of the clothes placed in the accommodation space, and the driving step supplies steam and hot air to the clothes to process the clothes.

[0071] The sensing step can be set to drive the mobile clothes hanger, but block the driving of either the steam generator or the compressor.

[0072] The driving speed of the driving unit in the sensing step can be set to be lower than the driving speed of the driving unit in the driving step.

[0073] If it is sensed in the sensing step that the clothes are heavier, the duration of the driving step can be set to be longer than when it is sensed that the clothes are lighter.

[0074] If it is sensed in the sensing step that the clothes are heavier, the driving time of the steam generator in the driving step can be set to be longer than when it is sensed that the clothes are lighter.

[0075] If it is sensed in the sensing step that the laundry is heavy, then in the driving step, the driving time of the compressor can be made longer than when it is sensed that the laundry is light, or the driving rpm of the compressor can be set to be greater than when it is sensed that the laundry is light.

[0114] Figure 3 The appearance of the laundry treatment apparatus 1 of the present invention is shown.

[0115] Refer to Figure 3 As shown in (a) of [], the laundry treatment apparatus of the present invention may include a cabinet 100 forming the appearance and a door 11 rotatably coupled to the cabinet 10.

[0116] The door 11 may be provided such that its height and width are the same as the front surface of the cabinet 100, and the door 11 may form the front surface of the laundry treatment apparatus 1.

[0117] The door 11 may have an input unit for receiving an instruction for operating the laundry treatment apparatus and may have a display unit for visually, audibly, etc., displaying the operating state of the laundry treatment apparatus to the outside.

[0118] Refer to Figure 3In (b) of this, an inner housing 20 may be provided inside the housing 10, and the inner housing 20 has a receiving space 21 for receiving clothes. The inner housing 20 may have an opening 21 for introducing and removing clothes in the front, and the opening 21 may be shielded by the door 11.

[0119] The inner housing 20 may be made of a plastic resin series, and may be made of a reinforced plastic resin series that will not deform even in an environment of air that is hotter than normal temperature air or heated air (hereinafter, hot air) and steam or moisture.

[0120] The inner housing 20 may be set to have a height greater than the width. Thus, the clothes can be received in the receiving space 21 without being folded or wrinkled.

[0121] The clothes processing apparatus 1 of the present invention may include a hanger portion capable of placing clothes on the receiving space 21 of the inner housing 20. The hanger portion may be set to be installed on the inner housing 20 and placed on the movable hanger 100 for placing clothes.

[0122] The movable hanger 100 may be set to be exposed on the upper inner surface of the inner housing 20 so that the hanger portion can be placed on the movable hanger 100. The movable hanger 100 may be set to be able to reciprocate on the upper surface of the inner housing 20 to shake the clothes. Later, the detailed structure of the movable hanger 100 will be described.

[0123] If the clothes are placed on the movable hanger 100, the clothes can be placed in the receiving space 21 in a state of floating in the air and stretching in the height direction. Thus, the clothes placed in the receiving space 21 can be evenly exposed to hot air and steam, and can be de-wrinkled using their own weight.

[0124] The clothes processing apparatus of the present invention may further include a pressing portion 40 that is combined with the inner surface of the door 11 and can fix clothes.

[0125] The pressing portion 40 may be set to be rotatably combined inside the door 11 to press the clothes fixed to the inner surface of the door 11 against the inner surface of the door 11.

[0126] The pressing portion 40 may generate desired creases on both side surfaces of the clothes.

[0127] The clothes processing apparatus of the present invention may further include a mechanical chamber 30, and various devices capable of supplying one or more of hot air or steam to the receiving space 21, or capable of purifying or dehumidifying the outside air of the housing 10 are provided in the mechanical chamber 30.

[0128] The mechanical chamber 30 may be configured to be separated or partitioned from the inner housing 20, but is provided to communicate with the inner housing 20.

[0129] The mechanical chamber 30 may be disposed at the lower part of the inner housing 20. Thus, if hot air and steam with a lower density are supplied to the inner housing 20, the hot air and steam can naturally be supplied to the laundry.

[0130] The mechanical chamber 30 may include a circulation duct and a plurality of heat exchangers. The circulation duct circulates the air inside the inner housing 20, and the plurality of heat exchangers are disposed on the circulation duct to cool the air to condense it or to heat the air.

[0131] The mechanical chamber 30 may have a heat pump system including a compressor. The compressor may be connected to the plurality of heat exchangers to compress the refrigerant that cools or heats the air.

[0132] The mechanical chamber 30 may further have a steam supply unit 50 capable of supplying steam to the inside of the inner housing 20. The steam supply unit 50 may generate steam by heating water. The laundry accommodated inside the inner housing is exposed to the hot air generated by the heat pump system and the steam generated by the steam supply unit 50, and is deodorized, sterilized, wrinkle-removed, and dried.

[0133] In front of the mechanical chamber 30, there may be included a water tank 31 for supplying water for generating the steam and a drain tank 32 for collecting the water condensed in the circulation duct.

[0134] The water tank 31 and the drain tank 32 may be detachably provided in front of the mechanical chamber 30. Thus, even if the laundry treatment apparatus of the present invention is not disposed near a water supply source or a drain, the user can detach and carry the water tank 31 and the drain tank 32 when needed.

[0135] The water tank 31 and the drain tank 32 may be arranged side by side in the width direction of the mechanical chamber 30.

[0136] In addition, the mechanical chamber 30 may further include a drawer 33 for accommodating articles such as those required for managing the laundry. The drawer 33 may be provided to be able to be drawn out from the mechanical chamber 30, and a space capable of accommodating articles such as an iron may be provided inside.

[0137] The laundry treatment apparatus 1 of the present invention may be provided with a mounting table 60 capable of mounting an additional shelf inside the inner housing 20. The mounting table 60 may be provided to protrude from positions at the same height on both side surfaces of the inner housing 20.

[0138] The placement table 60 may be provided with a light-emitting portion that irradiates light into the interior of the inner housing 20. The light-emitting portion may be configured to irradiate light onto the inner side surface of the inner housing 20 to prevent glare.

[0139] Figure 4 An embodiment of the structure of the machine room is shown.

[0140] The machine room 30 may be disposed at the lower part of the inner housing 20, providing a space for arranging the heat pump system 80 and the steam supply unit 50, and including a duct 90 that provides a flow path for circulating the air inside the inner housing 20.

[0141] The duct 90 may form a circulation flow path that is respectively communicated with the inflow port and the discharge port of the inner housing 20, and may form a space for the air inside the inner housing 20 to move. A blower fan may be disposed inside the duct 90. The blower fan may generate a pressure difference for sucking and discharging the air inside the accommodation space 21.

[0142] The duct may be arranged in a rectangular shape with a part of the upper part open, and an additional cover is combined at the upper part to complete the internal flow path. The duct 90 may include: an inflow duct 91, which is communicated with the inner housing 20 to allow air to flow in; a discharge duct 92, which is separated from the inflow duct 91 and communicated with the inner housing 20 to discharge air; and a moving duct 93, which connects the inflow duct 91 and the discharge duct 92 to form a flow path for air to move.

[0143] The heat pump system 80 may include an evaporator 81, a condenser 82, and a compressor 83. The evaporator 81 is accommodated inside the duct 90 to cool the air. The condenser 82 heats the air passing through the evaporator 81 to generate hot air. The compressor 83 compresses the refrigerant passing through the evaporator 81, heats it, and supplies it to the condenser 82. The heat pump system 80 may further include an expansion valve, which expands the refrigerant passing through the condenser 82, cools it, and then conveys it to the evaporator 81.

[0144] The evaporator 81 and the condenser 82 may be accommodated in the moving duct 93, and the compressor 82 and the expansion valve may be arranged outside the duct 90.

[0145] The evaporator 81 and the condenser 83 may be arranged along the direction of air movement. For example, the evaporator 81 may be arranged at a position closer to the inflow duct 91 than the condenser 83, and the condenser 83 may be arranged at a position closer to the discharge duct 92 than the evaporator 81.

[0146] The steam supply unit 50 may be arranged inside the duct 90.

[0147] The steam supply unit 50 may be disposed outside the pipe 90 without obstructing the flow of air moving along the pipe 90.

[0148] The steam supply unit 50 may include a steam generator 51 and a steam nozzle 52. The steam generator 51 receives and stores water, heats the water using a heater or the like inside to generate steam, and the steam nozzle 52 supplies the steam generated in the steam generator 51 to the accommodation space 21.

[0149] The steam nozzle 52 may be arranged to communicate with the inner housing 20 and may be disposed adjacent to the discharge pipe 92. The steam generator 51 may be placed and supported on the upper part of the pipe 90 and may be arranged to support the steam nozzle 52.

[0150] The steam supply unit 50 may further include a recovery pipe 54 that connects the steam nozzle 52 and the steam generator 51.

[0151] The recovery pipe 54 may recycle the water that has not been discharged to the outside and has condensed in the steam nozzle 52 back to the steam generator 51. The steam nozzle 52 may be arranged at a position closer to the upper part than the steam generator 51, so that steam is automatically supplied to the inner housing 20 under the action of the density difference, and water is recovered to the steam generator 51 under the action of gravity.

[0152] The steam nozzle 52 may be made of a plastic material or the like instead of a simple hose, and the steam nozzle 52 may be arranged in a housing shape capable of accommodating any one or more of steam, air, and water inside.

[0153] The steam supply unit 50 may further include a steam pipe 53 that connects the steam generator 51 and the steam nozzle 52. The steam generated in the steam generator 51 may be supplied inside the steam nozzle 52 along the steam pipe 53 and then supplied inside the inner housing 20.

[0154] The machinery room 30 may further include a water supply unit 60 that can supply water for generating steam in the steam supply unit 50.

[0155] The water supply unit 60 may be arranged to receive water from a water tank 31 placed in front of the machinery room 30 and then supply it to the steam supply unit 50.

[0156] The water supply unit 60 may include a water supply pipe 61 that receives water from the water tank 31, a supply pipe 63 that supplies the water in the water supply pipe 61 to the steam supply unit 50, and a water supply pump 62 that provides the power for supplying the water in the water supply pipe 61 to the supply pipe 63.

[0157] The water tank 31 can be detachably provided in front of the pipeline 90, and the water supply pump 62 can be arranged outside the pipeline 90.

[0158] The supply pipe 63 can be arranged to communicate with the steam generator 51 to supply water to the steam generator 51.

[0159] Alternatively, the supply pipe 63 can be arranged to communicate with the steam nozzle 52 to supply water to the steam nozzle 52. That is, the water supply unit 60 can also be arranged to directly supply water to the steam nozzle 52 and indirectly supply water to the steam generator 51 through the recovery pipe 54. Thus, the flow path structure can be simplified.

[0160] The machine room 30 can further include a drainage unit 70 that collects the water condensed in the evaporator 81 into the drainage tank 32.

[0161] The drainage unit 70 can include a discharge pipe 71, a drainage pump 72, and a drainage pipe 73. The discharge pipe 71 communicates with the lower surface of the pipeline 90 to discharge the water collected at the lower part of the pipeline 90 to the outside of the pipeline 90. The drainage pump 72 supplies the water discharged by the discharge pipe 71 to the drainage tank 32, and the drainage pipe 73 supplies the water supplied to the drainage pump 72 to the drainage tank 32.

[0162] On the other hand, the drainage unit 70 can further include a recovery pipeline 74 that communicates the pipeline 90 with the drainage tank 32 to redirect the water in the drainage tank 32 back into the pipeline 90. Thus, even when the drainage tank 32 is at full water level, it can prevent the water collected in the drainage tank 32 from leaking to the outside.

[0163] When the clothes treatment device of the present invention performs renovation operations on clothes such as sterilization, deodorization, wrinkle removal, and drying, it can supply hot air and steam to the inner housing 20 through the machine room 30 at an appropriate time, and can condense and collect the moisture discharged from the inner housing 20 into the drainage tank 32.

[0164] Figure 5 An embodiment of the mobile clothes hanger 100 of the clothes treatment device of the present invention is shown.

[0165] Refer to Figure 5(a), the mobile clothes hanger 100 may include a hanging rack portion 700, a power transmission portion 400, a connection portion 600, and a driving portion 200. The clothes or the clothes hanger portion 900 is placed on the hanging rack portion 700. A plurality of the power transmission portions 400 are combined with the hanging rack portion 700 to support the load of the clothes. The connection portion 600 connects the plurality of power transmission portions 400. The driving portion 200 provides power for reciprocating movement of the connection portion 600 and the plurality of power transmission portions 400.

[0166] The plurality of power transmission portions 400 may be spaced apart along the direction in which the clothes are arranged in the accommodation space 21.

[0167] The plurality of power transmission portions 400 may be arranged along the height direction of the clothes processing device. The connection portion 600 may be arranged to be placed on the upper surface of the inner housing 20.

[0168] The connection portion 600 may be integrally provided with the plurality of power transmission portions 400, and may be provided such that the upper portion is connected to the driving portion 200.

[0169] The driving portion 200 and the connection portion 600 may be supported by an additional support frame and arranged on the upper portion of the inner housing 20.

[0170] The connection portion 600 may include a connecting rod 630 provided in a rod shape. The connecting rod 630 may be connected to the driving portion 600 in a non-rotating rod yoke structure.

[0171] Thus, if the driving portion 600 generates rotational power, the connecting rod 630 may reciprocate along the length direction or the direction in which the power transmission portions 400 are spaced apart.

[0172] The driving portion 200 may include a motor portion 210, a power shaft 240, a transmission portion 230, and a displacement generating portion 300. The motor portion 210 transmits power for reciprocating movement of the connecting rod 630. The power shaft 240 rotates under the action of the motor portion 210. The transmission portion 230 transmits the power of the power shaft 240. The displacement generating portion 300 is connected to the transmission portion 230 to deform the rotational movement of the power shaft 240 into a movement along a preset trajectory.

[0173] For example, the transfer part 230 may include a transfer rod 236. One end of the transfer rod 236 is coupled to the power shaft 240, and the other end extends in the radial direction of the rotary shaft 210 such that the transfer rod 236 rotates together with the power shaft 240. The displacement generating part 300 may include an eccentric shaft 310 which is coupled to the other end of the transfer rod 236 and is coupled to the connecting rod 630. The eccentric shaft 310 may be arranged to rotate along a trajectory longer than that of the power shaft 240.

[0174] Referring to Figure 5 In (b) of the figure, the connecting rod 630 may have a slit 631 into which the eccentric shaft 310 is inserted, and the slit 631 may be formed perpendicular to the moving direction of the connecting rod 630. For example, the slit 631 may be formed in the thickness direction of the connecting rod 630.

[0175] The length of the slit 631 may be set to be more than twice the rotation radius R of the eccentric shaft 310, and the width of the slit 631 may be formed to be greater than the diameter of the eccentric shaft 310.

[0176] Figure 6 An operation example of the mobile clothes hanger is shown.

[0177] Referring to Figure 6 In (a) of the figure, the power shaft 240 is fixed in position, and the eccentric shaft 310 draws a trajectory along the rotation radius (R) with the power shaft 240 as a reference and continuously rotates in either the clockwise or counterclockwise direction.

[0178] The eccentric shaft 310 may rotate the power shaft 240 and move it to the right side of the power shaft 240. During this process, the slit 631 provided in the connecting rod 630 may receive the force moving to the right side by the eccentric shaft 310, and the connecting rod 630 may move to the right side.

[0179] Referring to Figure 6 In (b) of the figure, the eccentric shaft 310 may further continuously rotate in the same direction and move to the left side of the power shaft 240. During this process, the slit 631 provided in the connecting rod 630 may receive the force moving to the left side by the eccentric shaft 310, and the connecting rod 630 may move to the left side.

[0180] If the eccentric shaft 310 further rotates, the positions in (a) of the above Figure 6 and the position in (b) of Figure 6 will be repeated, and the connecting rod 630 may move back and forth to the left and right.

[0181] As a result, the power transmission unit 400 coupled to the connecting rod 630 can also move reciprocally left and right, causing the hanger unit 700 coupled to the power transmission unit 400 and the clothes placed on the hanger unit 700 to also sway.

[0182] If the eccentric shaft 310 rotates one full circle, the connecting rod 630 can move reciprocally left and right once and can change the moving direction twice.

[0183] Figure 7 Another embodiment of the moving hanger 100 of the clothes processing apparatus according to the present invention is shown.

[0184] The moving hanger 100 of the new embodiment may also include a power transmission unit 400 disposed on the upper part of the inner housing 10 and configured to rock the hanger 900.

[0185] A hanger unit 700 on which the hanger 900 can be placed or rested may be provided below the power transmission unit 400.

[0186] Thus, if the power transmission unit 400 moves, the hanger unit 700 moves, and the hanger 900 placed on the hanger unit 700 sways, thereby being able to exhibit the effect of shaking the clothes.

[0187] A plurality of the power transmission units 400 may be provided, and a plurality of the hanger units 700 coupled to the power transmission units 400 may also be provided. Thus, a large number of clothes corresponding to the number of the power transmission units 400 can be placed inside the inner housing 20 and refurbished.

[0188] The moving hanger 100 may further include a driving unit 200 that provides power for moving the power transmission unit 400.

[0189] If the driving unit 200 can transmit power to the power transmission unit 400, it may also be configured to be exposed to the inside of the inner housing 20. However, since the driving unit 200 is configured to operate by receiving electric energy, it is preferably blocked from being exposed to steam or hot air.

[0190] Therefore, the driving unit 200 may be disposed between the upper surface of the inner housing 20 and the box body 10 so as to be blocked from being exposed to the accommodation space 21.

[0191] The power transmission unit 400 may penetrate through the upper part of the inner housing 20 and receive the power of the driving unit 200. The power transmission unit 400 may penetrate through the upper part of the inner housing 20 and extend downward so that its lower end is exposed to the accommodation space 21.

[0192] The power transmission unit 400 may be provided in a rod shape, a tube shape, a plate shape, etc., with a length greater than the thickness.

[0193] On the other hand, the upper surface of the inner housing 20 may be configured to support the loads of the power transmission unit 400 and the driving unit 200. However, when the power transmission unit 400 holds the clothes and moves, the load of the driving unit 200 is relatively large. Therefore, the clothes treatment apparatus 1 of the present invention may further include a support unit 800 to stably dispose the moving hanger 100 on the upper surface of the inner housing 20.

[0194] The support unit 800 may be disposed on the upper portion of the inner housing 20, but is supported by being coupled to the cabinet 1. The support unit 800 may be made of a metal material with a shape that is difficult to change.

[0195] The power transmission unit 400 and the driving unit 200 may be placed on the support unit 800 and disposed on the upper surface of the inner housing 20.

[0196] On the other hand, the driving unit 200 includes a motor that rotates a rotating shaft. The driving unit 200 may be configured to move the power transmission unit 400 by using the power that rotates the rotating shaft.

[0197] However, it is difficult to sufficiently displace and shake the power transmission unit 400 only by the in-situ rotation of the rotating shaft.

[0198] Therefore, the moving hanger 100 may further include a displacement generation unit 300, which is coupled to the rotating shaft to generate sufficient displacement capable of moving the power transmission unit 400.

[0199] The displacement generation unit 300 may connect the rotating shaft and the power transmission unit 400 to each other, and is configured to transmit the power of the rotating shaft to the power transmission unit 400.

[0200] The displacement generation unit 300 may include an eccentric shaft, which rotates by drawing a trajectory larger than the diameter of the rotating shaft using the rotating shaft. The eccentric shaft may generate displacement that causes the power transmission unit 400 to reciprocate within a preset range.

[0201] Thus, if the driving unit 200 operates, the power generated on the rotating shaft is transmitted to the power transmission unit 400, causing the power transmission unit to reciprocate within a preset range.

[0202] The moving hanger 100 may be configured to rock the clothes by reciprocally rotating the power transmission unit 400, rather than causing the power transmission unit 400 to reciprocate left and right.

[0203] Specifically, the mobile clothes hanger 100 can be configured to cause the power transmission part 400 to reciprocally rotate within a preset angular range, rather than linearly reciprocate.

[0204] Thereby, the power transmission part 400 can be configured to reciprocally rotate left and right at a specified position, causing the clothes placed on the power transmission part 400 to only reciprocally rotate left and right without linearly reciprocating.

[0205] As a result, even if the clothes rotate inside the inner housing 20 by means of the power transmission part 400, the movement of the center of gravity may be restricted inside the inner housing 20. Therefore, even when the mobile clothes hanger 100 operates, the vibration generated inside the inner housing 20 can be significantly reduced, and as a result, the generation of noise can be minimized to the greatest extent.

[0206] The mobile clothes hanger 100 may further include a reciprocating rotation part 500 that converts the continuous rotational energy generated in the driving part 200 or the displacement generating part 300 into the reciprocating rotational movement of the power transmission part 400.

[0207] The reciprocating rotation part 500 can be configured to connect the displacement generating part 300 and the power transmission part 400 to each other. The reciprocating rotation part 500 is configured to connect the displacement generating part 300 and the power transmission part 400 to each other at a position closer to the upper part than the inner housing 20, thereby being able to prevent the clothes from being damaged by the mobile clothes hanger 100.

[0208] On the other hand, the mobile clothes hanger 100 can also be configured to cause only any one of the plurality of power transmission parts 400 to reciprocally rotate.

[0209] However, if only one power transmission part 400 rotates, there is a risk that the clothes placed on the rotating power transmission part will collide with the clothes placed on other power transmission parts 400, damaging the clothes or the mobile clothes hanger 100.

[0210] Therefore, the mobile clothes hanger 100 is preferably configured to cause all of the plurality of power transmission parts 400 to rotate. In addition, the mobile clothes hanger 100 can be configured to cause the plurality of power transmission parts 400 to rotate simultaneously at the same angle. Thereby, collisions between the power transmission parts 400 can be prevented.

[0211] On the other hand, directly transmitting the power of the driving part 200 in the mobile clothes hanger 100 to all the power transmission parts may be more conducive to controlling the rotation of the power transmission parts 400.

[0212] However, if a plurality of driving units 200 are provided and power is transmitted to each power transmission unit 400 respectively, it will not only impose an excessive load on the upper part of the inner housing 20, but may also cause inconvenience in controlling a plurality of driving units 200.

[0213] Therefore, the mobile clothes hanger 100 can be configured such that one driving unit 200 rotates a plurality of power transmission units 400.

[0214] At this time, if the displacement generating unit 300 and the reciprocating rotation unit 400 are connected to transmit the power transmitted from one driving 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 may become complicated and their reliability may decrease.

[0215] Therefore, the mobile clothes hanger 100 of the present invention can be configured to transmit only the power generated in the driving unit 200 to a part of the plurality of power transmission units 400.

[0216] The reciprocating rotation unit 500 can be configured to transmit only the power transmitted from the driving unit 200 or the displacement generating unit 300 to a part of the power transmission units 400.

[0217] Therefore, the structure of the reciprocating rotation unit 500 becomes simple, thereby ensuring the reliability of power transmission.

[0218] On the other hand, the mobile clothes hanger 100 may further include a connecting unit 600 configured to transmit the power transmitted to a specific power transmission unit 400 to another power transmission unit 400.

[0219] For example, the connecting unit 600 can be configured to connect a plurality of power transmission units 400 to each other. Thus, if any one of the power transmission units 400 rotates, the power transmission units 400 adjacent to or separated from it can all rotate.

[0220] Specifically, the mobile clothes hanger 100 can be configured to transmit only the power of the driving unit 200 to any one of the plurality of power transmission units 400, and transmit the power transmitted to the power transmission unit to other power transmission units 400 through the connecting unit 600.

[0221] The displacement generating unit 300 or the reciprocating rotation unit 400 can be configured to concentrate and transmit the power generated in one driving unit 200 to one power transmission unit 400. In addition, the connecting unit 600 can transmit the power transmitted to a specific power transmission unit 400 to all power transmission units 400.

[0222] The connecting part 600 can be set as a rigid body to connect all the power transmission parts 400, and all the power transmission parts 400 can be set to rotate simultaneously in the same direction and at the same angle by using the connecting part 600.

[0223] Thus, the mobile clothes hanger 100 of the present invention can use a simple structure to make a plurality of power transmission parts 400 rotate reciprocally simultaneously or synchronously at the same angle by using one driving part 200.

[0224] Figure 8 The structure of the mobile clothes hanger 100 is shown.

[0225] The mobile clothes hanger 100 may include a driving part 200, a plurality of reciprocating rotation parts 500, and a connecting part 600. The driving part 200 is fixed on the upper part of the inner housing 20 and provides power for moving the power transmission part. A plurality of the reciprocating rotation parts 500 are respectively combined with a plurality of the power transmission parts 400, receive the power from the driving part 200, and rotate in a manner of repeatedly switching the rotation direction. The connecting part 600 is set to connect the plurality of reciprocating rotation parts to each other.

[0226] The connecting part 600 may include a single link, and the single link connects the plurality of reciprocating rotation parts 500 to make the plurality of reciprocating rotation parts 500 rotate integrally.

[0227] The connecting part 600 may also be set to connect the plurality of power transmission parts 400.

[0228] If the connecting part 600 is set to connect the plurality of reciprocating transmission parts 500, the connecting part 600 can be set at a position closer to the upper part than the support part 800, so that the connecting part 600 can be prevented from being exposed inside the inner housing 20.

[0229] If the connecting part 600 is set as a single link, interference between the driving part 200 and the connecting part 600 can be minimized.

[0230] For example, the single link can be combined in front of or behind the reciprocating rotation part 500, and the later-described displacement generating part 300 or the driving part 200 can be arranged behind or in front of the reciprocating rotation part 500.

[0231] The connecting part 600 can be set to reciprocate in the width direction of the inner housing 20 and make the plurality of reciprocating rotation parts 500 rotate.

[0232] The driving unit 200 may include a motor 210, a power shaft 240, and a transmission unit 230. The motor 210 rotates a rotating shaft 210, the power shaft 240 is arranged to rotate together when the rotating shaft 210 rotates, and the transmission unit 230 connects the power shaft 240 and the rotating shaft 210 to transmit the rotational force of the rotating shaft 210 to the power shaft 240.

[0233] The motor 210 may be arranged to be fixed to the upper part of the inner housing 20 and rotate the rotating shaft 220. However, the rotating shaft 220 is arranged to rotate at a speed faster than an appropriate period for reciprocally rotating the power transmission unit 400 by the motor 210. If the RPM of the rotating shaft is reduced in consideration of this, there may be a risk that the output of the motor 210 cannot be transmitted to the power transmission unit 400.

[0234] To solve such a problem, the transmission unit 230 may be arranged to transmit the output of the rotating shaft 220 to the power transmission unit 400 as it is, or may transmit it after reducing the RPM of the rotating shaft 220.

[0235] The transmission unit 230 is arranged to be connected to the rotating shaft 220 to rotate, but may be arranged to have a diameter larger than that of the rotating shaft 220. Thus, the transmission unit 230 may be arranged to transmit the torque of the rotating shaft 220 while rotating more slowly than the RPM of the rotating shaft 220.

[0236] The power shaft 240 may be arranged to rotate by means of the transmission unit 230, may be separately arranged from the rotating shaft 230, and is a configuration for directly transmitting power to the power transmission unit 400.

[0237] The reciprocating rotation unit 500 may be arranged to be combined with the power transmission unit 400 and be able to rotate together with the power transmission unit 400.

[0238] The reciprocating rotation unit 500 may include a reciprocating lever 510, and the reciprocating lever 510 is combined with the upper part of the power transmission unit 400 to rotate the power transmission unit 400.

[0239] The reciprocating lever 510 may be arranged in a rib or rod shape with its rotation center combined with the support shaft 410.

[0240] The reciprocating lever 510 may be respectively combined with the upper ends of a plurality of the power transmission units 400, and a part of the reciprocating levers 510 may be arranged to be connected to the transmission unit 230 to receive the power of the motor 210.

[0241] The reciprocating lever 510 can be configured to reciprocally rotate at a preset angle if the transmission part 230 rotates by using the motor 210. The power transmission part 400 can be configured to be coupled to the rotation center of the reciprocating lever 510 to rotate together with the reciprocating lever 510.

[0242] A plurality of reciprocating levers 510 can be arranged to be connected by a connecting part 600.

[0243] The connecting part 600 can be configured to connect one end of a plurality of reciprocating levers 510.

[0244] Thus, as long as any one of the plurality of reciprocating levers 510 rotates, the connecting part 600 can be moved to enable the plurality of reciprocating levers 510 to rotate simultaneously and synchronously.

[0245] The power transmission part 400 and the reciprocating lever 510 can be supported by the support part 800. In addition, the motor 210 and the transmission part 230 can also be supported by the support part 800.

[0246] Figure 9 The separation of the mobile clothes hanger 100 of the present invention from the inner housing 20 is shown.

[0247] The power transmission part 400 can be configured to extend from the upper part to the lower part of the inner housing, and the hanger part 700 can be coupled to the lower part of the power transmission part 400.

[0248] The reciprocating rotation part 500 can be coupled to each of the power transmission parts 400, and can be coupled to the upper part of the power transmission part 400 to be easily connected to the driving part 200.

[0249] A plurality of the power transmission parts 400 and the reciprocating rotation parts 500 can be provided, and can be arranged at preset intervals in the width direction of the inner housing.

[0250] The connecting part 600 is configured to connect a plurality of the power transmission parts 400 or a plurality of the reciprocating rotation parts 500 to each other. Thus, the connecting part 600 can be configured to rotate a plurality of the power transmission parts 400 or a plurality of the reciprocating rotation parts 500 as a whole simultaneously.

[0251] The power transmission part 400 can include a support shaft 410 that penetrates the upper part of the inner housing 20 and is coupled to the reciprocating lever 510.

[0252] The support shaft 410 can penetrate the support part 800 and be exposed to the upper part of the support part 800 or the upper part of the inner housing 20.

[0253] The power transmission unit 400 may include an auxiliary support portion 420, which is coupled to the support shaft 410 and exposed to the accommodation space. The auxiliary support portion 420 may be provided in a rod shape, and a hanger portion 700 is coupled and fixed to the lower portion thereof.

[0254] The auxiliary support portion 420 may 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 by using the reciprocating lever 510, the auxiliary support portion 420 coupled to the support shaft 410 may also rotate to cause the hanger portion 700 to rotate left and right.

[0255] The reciprocating lever 510 may include a main lever 511 that directly receives power from the driving unit 200 to reciprocally rotate, and an auxiliary lever 512 that receives power from the main lever 511 through a connecting portion 600.

[0256] The main lever 511 may be provided as a single number and configured to directly receive power from the driving unit 200.

[0257] In the driving unit 200, the motor 210 may include a vertical motor 211 coupled to the support portion 800 and a vertical rotation shaft 221 that rotates by using the vertical motor 211.

[0258] The transmission unit 230 may include a power pulley 231, a transmission pulley 232, and a belt 233. The power pulley 231 is coupled to the vertical rotation shaft 221 and rotates together with the vertical rotation shaft 221. The transmission pulley 232 is coupled to the power shaft 240 to rotate the power shaft 240. The belt 233 connects a part of the outer circumferential surfaces of the power pulley 231 and the transmission pulley 232.

[0259] The transmission unit 230 may further include a pulley support portion 224 that supports the power shaft 240 and the transmission pulley 232 so that they can rotate. The pulley support portion 224 may be configured to support the transmission pulley 232 so that the transmission pulley 232 is arranged side by side with the power pulley 231, and may be arranged on the support portion 800.

[0260] The power shaft 240 may be configured to transmit the power transmitted from the rotation shaft 220 to one end of both ends of the main lever 511.

[0261] The power shaft 240 may be coupled to a later-described displacement generation unit 300 to cause the main lever 511 to reciprocally rotate about the support shaft 410.

[0262] The connecting part 600 may include a connecting bar 610 that connects an end of the main lever 511 that is not connected to the power shaft 240 and one end of the auxiliary lever 512 among both ends of the main lever 511.

[0263] The auxiliary lever 512 may be rotatably coupled to the support shaft 410 and may be configured to extend in one direction from a portion coupled to the support shaft 410 and connect to the connecting bar 610.

[0264] The connecting bar 610 may be configured in a straight frame form that connects one end of the main lever 511 and one end of a plurality of the auxiliary levers 512. At this time, one end of the main lever 511 and one end of the auxiliary lever 512 may be arranged side by side with respect to the connecting bar 610 or in the width direction.

[0265] The connecting bar 610 may be configured as a single unit and may be configured to rotate the main lever 511 and the auxiliary lever 512 simultaneously and synchronously about their respective support shafts 410.

[0266] The inner case 20 may have a through-hole 23, and a part of the support part 800 is disposed in the through-hole 23 so that the power transmission part 400 is exposed to the accommodation space 22.

[0267] The through-hole 23 may be provided on the upper surface 22 of the inner case, and the through-hole 23 may be provided along the direction in which the power transmission part 400 is arranged.

[0268] For example, the power transmission parts 400 may be arranged at intervals from each other in the width direction of the inner case, and the through-hole 23 may be arranged in the width direction of the inner case.

[0269] The clothing treatment apparatus 1 of the present invention may further include a support frame 12 that is disposed outside the inner case and supports the cabinet 1.

[0270] The support frame 12 may be arranged at each position corresponding to the corners of the cabinet 1 or the corners of the inner case 20 and may be made of a metal material that maintains the appearance of the clothing treatment apparatus. Both ends of the support part 800 are disposed on the support frame 12 and supported, thereby preventing unnecessary impact or load from being transmitted to the upper surface 22 of the inner case.

[0271] Figure 10 An exploded perspective view of the mobile clothes hanger 100 of the present invention is shown.

[0272] The power transmission unit 400 may include a support shaft 410, an auxiliary support portion 420, and a hanger portion 700. The support shaft 410 penetrates through the upper surface of the inner housing 20 and is coupled to the reciprocating lever 510. The auxiliary support portion 420 is coupled to the support shaft 410 and is exposed to the accommodation space 21. The hanger portion 700 is coupled to the auxiliary support portion 420 and is provided for the hanger portion 900 or clothes to be placed thereon.

[0273] The support shaft 410 is provided in a long cylindrical shape with a length greater than the diameter, and can be easily rotated by the reciprocating lever 510.

[0274] The diameter of the support shaft 410 is much smaller than that of the auxiliary support portion 420, so it can penetrate the inner housing or the support portion 800 with a smaller area. Thus, the possibility of hot air or steam supplied to the accommodation space leaking to the upper part of the inner housing 20 can be further reduced.

[0275] The cross-sectional area of the auxiliary support portion 420 may be larger than that of the support shaft 410, and the length may be greater than that of the support shaft 410. Thus, the rigidity and area for the auxiliary support portion 420 to support the hanger portion 700 and the hanger portion 900 and enable their rotation can be ensured.

[0276] The support portion 800 may include a support plate member 810, and the support plate member 810 may be provided for the support shaft 410 to penetrate through and support the driving unit 200. The support plate member 810 may be formed of a metal plate, so rigidity and durability can be ensured, and the support plate member 810 may extend in the direction in which a plurality of the power transmission units 400 are arranged.

[0277] The support portion 800 may include an extension main body 812 extending upward from both ends of the support plate member 810 and a placement main body 813 extending from the extension main body 821 and placed on the support frame 12, so as to form a space for the driving unit 200 and the reciprocating rotation unit 500 to be placed between the upper parts of the inner housing 20 and the box body 10.

[0278] The support portion 800 may include a shaft coupling portion 820 provided for the support shaft 410 to penetrate through.

[0279] A plurality of the shaft coupling portions 820 may be provided so as to be able to be set at positions corresponding to the positions where the power transmission units 400 are arranged, and the shaft coupling portions 820 may be arranged at intervals along the length direction of the support plate member 810.

[0280] On the other hand, the support part 800 may further include an auxiliary plate part 880 coupled to the lower part of the support plate part 810. The auxiliary plate part 880 may be made of a resin series and may be configured to accommodate a part of the outer circumferential surface of the power transmission part 400.

[0281] The auxiliary plate part 880 may include a plurality of accommodation holes 882, a plurality of extension steps 883, and a fixing plate 881. The plurality of accommodation holes 882 may be disposed in the lower part of the support plate part 810 to accommodate the power transmission part 400 so that it can rotate. The plurality of extension steps 883 extend from the accommodation holes 882 to have a larger width. The fixing plate 881 may extend from the extension steps 883 and face the support plate part 810, and may be coupled and fixed to the support plate part 810.

[0282] The accommodation holes 882 may be configured to be disposed at the upper ends of the support shaft 410 or the auxiliary support part 420 to prevent hot air or air from being discharged to the shaft coupling part 820. The extension steps 883 may serve to disperse the load or impact transmitted to the auxiliary plate part 880, and may serve to prevent the accommodation holes 882 from colliding with or interfering with the hanger part 900.

[0283] The support part 800 may further include a placement plate part 820 disposed on the upper part of the support plate part 810.

[0284] The placement plate part 820 may serve to support the bearing disposed on the shaft coupling part 820, and may also serve to prevent the reciprocating lever 510 and the connecting part 600 from colliding with or rubbing against the support plate part 810.

[0285] The placement plate part 820 may include a placement plate 861 and a placement hole 862. The placement plate 861 is disposed on the upper part of the support plate part 810, and the placement hole 862 penetrates through the placement plate 861 and is disposed in a region corresponding to the shaft coupling part 820.

[0286] The reciprocating lever 510 may include a main lever 511 and an auxiliary lever 512. The main lever 511 directly receives power from the driving part 200, and the auxiliary lever 512 receives the power from the main lever 511 through the connecting part 600.

[0287] The main lever 511 and the auxiliary lever 512 may be configured to be coupled to their respective support shafts 410 and rotate about the support shafts 410 as the rotation centers.

[0288] The connecting rod 610 may include a connecting body 611 and a connecting hook 612. The connecting body 611 may be disposed on the main lever 511 and the auxiliary lever 512 to connect them to each other. The connecting hook 612 protrudes from the connecting body 611 and is rotatably disposed on the main lever 511 and the auxiliary lever 512.

[0289] The reciprocating lever 510 may include a connecting bearing 513. The connecting bearing 513 is combined with one end of the main lever 511 and one end of the auxiliary lever 512 to support the connecting hook 612 so that it can rotate.

[0290] If the connecting rod 610 rotates left and right, the main lever 511 or the auxiliary lever 512 may reciprocate left and right.

[0291] The reciprocating rotating part 500 may further include a support bearing 530. The support bearing 530 may support the support shaft 410 or the reciprocating lever 510 so that it can rotate.

[0292] The support bearing 530 may accommodate the support shaft 410 so that it can rotate, and the support bearing 530 may be disposed on the shaft coupling part 620.

[0293] The reciprocating lever 510 may be disposed above the support bearing 530.

[0294] The support bearings 530 may also be stacked in a plurality of layers, or may be set as ball bearings or oil-free bearings.

[0295] The placement plate part 860 may be set to support the support bearing 530 to block the exposure of hot air or moisture from the outer peripheral surface of the support bearing 530.

[0296] In addition, the auxiliary plate member 880 may also be set to be disposed below the support bearing 530 to block the exposure of hot air or moisture from the outer peripheral surface of the support bearing 530.

[0297] Figure 11 The operation mode of the mobile clothes hanger 100 of the present invention is shown.

[0298] Refer to Figure 11 In (a) of, the main lever 511 may include a main body 5111. The main body 5111 is combined with the support shaft 410 and is combined with the connecting rod 610.

[0299] The main body 5111 may include a main central hole 5115 that is combined with the support shaft 410 and enables the support shaft 410 to rotate. The main body 5111 may be set to extend from the main central hole 5115 to both sides.

[0300] One end of the main body 5111 may be provided with a main receiving hole 5112 for receiving power from the sub-driving part 200, and the other end may include a main transmission hole 5113 for the connecting rod 610 to be placed and coupled.

[0301] The main body 5111 may further include a stepped portion 5114 that extends from the central hole towards the main receiving hole 5112 but forms a step. Under the action of the stepped portion 51140, one end of the main body 5111 or the main transmission hole 5113 may be configured at a position closer to the lower part than the main central hole 5115.

[0302] Thereby, it is possible to ensure the length of the power shaft 240 disposed above the main central hole 5115 or the eccentric shaft 310 described later extending from the transmission part 230.

[0303] On the other hand, the auxiliary lever 512 may include an auxiliary central hole 5125 coupled to the support shaft 410 and an auxiliary body 5121 that extends from the auxiliary central hole 5125 to one side and has an auxiliary transmission hole 5123 for coupling with the connecting rod 610.

[0304] The auxiliary body 5121 may be set to have a length shorter than that of the main body 5111.

[0305] The distance from the main central hole 5115 to the main transmission hole 5113 may be set to be the same as the distance from the auxiliary central hole 5125 to the auxiliary transmission hole 5123.

[0306] The connecting rod 610 may be placed above 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.

[0307] Refer to Figure 11 As shown in (b) of, the driving part 200 may be set such that the power shaft 240 is inserted into the main receiving hole 5112. Thus, the driving part 200 may be set to directly rotate the power shaft 240 to rotate the main receiving hole 5112 left and right.

[0308] In other words, only by the rotation of the power shaft 240, sufficient displacement cannot be generated to rotate the main receiving hole 5112 left and right with the main central hole 5115 as a reference.

[0309] For this reason, the mobile clothes hanger 100 of the present invention may include a displacement generating part 300 that is coupled to the power shaft 240 and generates a displacement greater than the rotation radius of the power shaft 240.

[0310] The displacement generation unit 300 can be set to convert the in-situ rotational motion of the power shaft 240 into a displacement motion that reciprocates within a preset range. The displacement motion can be transmitted to the reciprocating rotation unit 500 to cause the power transmission unit 400 to reciprocally rotate.

[0311] For example, the displacement generation unit 300 may further include an eccentric shaft 310 that extends from the power shaft 240 and rotates along a trajectory with a preset radius.

[0312] The diameter of the eccentric shaft 310 can be set to be smaller than the diameter or width of the main receiving hole 5112. Thus, the eccentric shaft 310 can be inserted into the main receiving hole 5112 and supported.

[0313] However, the preset 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 can be pushed by the eccentric shaft 310 and move left and right with respect to the main center hole 5115 as a reference.

[0314] As a result, if the eccentric shaft 310 rotates in a specific direction x, the main receiving hole 5112 of the main body 511 also reciprocally rotates in a preset direction y. As a result, the center hole 5115 of the main body can also rotate in the same direction as the main receiving hole 5112, and the main transmission hole 5113 can reciprocally rotate in a direction z opposite to the preset direction.

[0315] If the eccentric shaft 310 rotates, the support shaft 410 can reciprocally rotate together with the main center hole 5115, causing the power transmission unit 400 to reciprocally rotate. The main transmission hole 5113 also reciprocally rotates, causing the connecting rod 610 to reciprocally move, so that the auxiliary lever 521 can also reciprocally rotate around the auxiliary center hole 5125 and the support shaft 410. The power transmission unit 400 coupled to the auxiliary lever 521 can also reciprocally rotate.

[0316] Threads can be provided along the circumference on the upper part of the support shaft 410 for the power transmission unit 400.

[0317] The main transmission hole 5113 and the auxiliary center hole 5125 can be directly coupled to the support shaft 410 and fixed using a wire thread or the like.

[0318] However, the power transmission unit 400 may further include a transmission coupling part 415. After the support shaft 410 passes through the main transmission hole 5113 and the auxiliary center hole 5125, the transmission coupling part 415 is threadedly coupled with the support shaft 410 to fix the support shaft 410 to the main transmission hole 5113 and the auxiliary center hole 5125.

[0319] Therefore, the support shaft 410 and the reciprocating lever 510 are coupled by the transmission coupling part 415, enabling the support shaft 410 and the reciprocating lever 510 to rotate simultaneously.

[0320] Figure 12 The operation process of the mobile clothes hanger 100 of the present invention is shown.

[0321] Referring to Figure 12 (a) of, the main receiving hole 5112 in the main lever 511 can rotate to the left with reference to the main center hole 5115 by the rotation of the eccentric shaft 310. (①)

[0322] If the main receiving hole 5112 rotates to the left, the main center hole 5115 can also rotate counterclockwise. (②) During this process, the power transmission unit 400 coupled to the main center hole 5115 can rotate counterclockwise.

[0323] The main receiving hole 5113 can rotate counterclockwise around the main center hole 5115. At this time, the connecting rod 610 can move to the right as the main receiving hole 5113 moves. (③)

[0324] If the connecting rod 610 moves to the right, the auxiliary receiving hole 5123 in the auxiliary lever 512 rotates counterclockwise with reference to the auxiliary center hole 5125. Since the connecting rod 610 is connected to a plurality of the auxiliary levers 512, all the auxiliary levers 512 rotate counterclockwise. (④)

[0325] If the auxiliary lever 512 rotates counterclockwise, the power transmission unit 400 coupled to the auxiliary center hole 5125 also rotates counterclockwise. (⑤)

[0326] Referring to Figure 12 (b) of, the main receiving hole 5112 in the main lever 511 can rotate to the right with reference to the main center hole 5115 by the rotation of the eccentric shaft 310. (①)

[0327] If the main receiving hole 5112 rotates to the right, the main center hole 5115 can also rotate clockwise. (②) During this process, the power transmission part 400 coupled to the main center hole 5115 can rotate clockwise.

[0328] The main receiving hole 5113 rotates clockwise in the main center hole 5115. At this time, the connecting rod 610 can move to the left as the main receiving hole 5113 moves. (③)

[0329] If the connecting rod 610 moves to the left, the auxiliary receiving hole 5123 in the auxiliary lever 512 rotates clockwise with respect to the auxiliary center hole 5125. Since the connecting rod 610 is connected to a plurality of the auxiliary levers 512, all the auxiliary levers 512 rotate clockwise. (④)

[0330] If the auxiliary lever 512 rotates clockwise, the power transmission part 400 coupled to the auxiliary center hole 5125 also rotates clockwise. (⑤)

[0331] If this process is repeated, the main lever 511 receives power from the driving part 200 and reciprocally rotates clockwise and counterclockwise, so that the power transmission part 400 coupled to the main lever 511 can reciprocally rotate, causing the connecting rod 610 to reciprocally move left and right.

[0332] While the connecting rod 610 reciprocally moves left and right, it can cause the auxiliary lever 512 to reciprocally rotate, so that the power transmission part 400 coupled to the auxiliary lever 512 can reciprocally rotate.

[0333] The connecting rod 610 is made of a rigid body, and the auxiliary lever 512 and the main lever 511 are coupled to the connecting rod 610 at positions separated from the support shaft 410 by the same length.

[0334] Therefore, the auxiliary lever 512 and the main lever 511 can reciprocally rotate at the same angle using the connecting rod 610. As a result, all the power transmission parts 400 can rotate simultaneously and synchronously at the same angle, and the reciprocally rotating angles can also be the same as each other.

[0335] The main lever 511 can be disposed between the auxiliary levers 512. In addition, the auxiliary levers 512 can be symmetrically disposed with respect to the main lever 511. Thus, a load can be evenly applied to both sides of the connecting rod 610 connected to the main lever 511.

[0336] 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 arranged or sequenced arbitrarily.

[0337] Figure 13 The way the mobile clothes hanger of the present invention operates is shown.

[0338] Refer to Figure 13 In (a) of, when the driving unit 200 operates, the power transmission unit 400 can rotate to the right through the reciprocating rotation unit 500. At this time, all the plurality of power transmission units 400 connected to the connection unit 600 can also rotate to the right.

[0339] Refer to Figure 13 In (b) of, when the driving unit 200 further operates, the power transmission unit 400 can rotate to the left through the reciprocating rotation unit 500. At this time, all the plurality of power transmission units 400 connected to the connection unit 600 can also rotate to the left.

[0340] If this process is repeated, the power transmission unit 400 can be rotated left and right.

[0341] At this time, the power transmission unit 400 can be set to rotate left and right while being fixed at a specified position. The power transmission unit 400 can be fixed to the support unit 800 so that its position does not change in the front, back, left, or right directions during rotation.

[0342] The power transmission unit 400 can be fixed so that its position does not move based on the up-down direction, front-back direction, or width direction.

[0343] However, the power transmission unit 400 can be set to rotate left and right with the up-down direction or height direction in which the power transmission unit extends as the rotation axis. As a result, if the driving unit 200 is driven, the hanger unit 700 can reciprocate left and right with the power transmission unit 400 as the axis without moving its position.

[0344] Refer to Figure 13 In (c) of, the clothes hanger unit 900 can include a hook portion 910 placed on the hanger unit 700 and a placement portion 900 combined with the hook portion 910. A surface portion 950 for preventing clothes from sliding can be provided on the surface of the placement portion 950.

[0345] The placement portion 950 can be symmetrically arranged left and right with the hook portion 910 as the center. The clothes hanger unit 900 can be placed on the hanger unit 700 so that the placement portion 950 is arranged in the front-back direction.

[0346] If the power transmission unit 400 rotates to the left, with the hook portion 910 of the hanger portion 900 as a reference, the left side of the placement portion 950 can rotate to the left, and the right side of the placement portion 950 can rotate to the right. At this time, the rotation angle (I) of the left side of the placement portion 950 can be the same as the rotation angle (θ) of the right side of the placement portion 950, and the distance moved by the left side of the placement portion 950 can be the same as the distance moved by the right side of the placement portion 950.

[0347] As a result, the weight and force moving to the left with the hanger portion 900 as a reference are the same as the weight and force moving to the right, so they can cancel each other out.

[0348] Similarly, even if the power transmission unit 400 rotates to the right, as a result, the weight and force moving to the left with the hanger portion 900 as a reference are the same as the weight and force moving to the right, so they can cancel each other out.

[0349] As a result, even if the power transmission unit 400 rotates, it is possible to cancel out the multiple forces applied to the hanger portion 900. As a result, the vibration force, exciting force, or inertial force generated by the hanger portion 900 itself can be minimized. Thus, the inertial force and the like generated in the multiple power transmission units 400 can be minimized, so that the vibration or noise generated by the entire mobile hanger 100 can be minimized, and the vibration or noise generated in the entire laundry processing apparatus 1 can be significantly reduced.

[0350] As a result, even if the driving unit 200 drives at maximum output, the entire mobile hanger 100 or the laundry processing apparatus 1 will not generate significant vibration.

[0351] Alternatively, the surfaces of the clothes placed on the hanger portion 900 rotate left and right and shake respectively, so as to ensure a greater dust removal force.

[0352] In addition, the power transmission unit 400 can be arranged to penetrate the inner housing 20, and can be arranged to receive the power and rotate reciprocally in the clockwise and counterclockwise directions.

[0353] The power transmission unit 400 can be arranged to reciprocally rotate left and right in a fixed position at the upper part of the accommodation space 21.

[0354] The power transmission unit 400 can be fixed so as not to change in the up, down, left, and right directions. In addition, not only the upper part of the power transmission unit 400, but also its lower part is fixed so as not to change in the up, down, left, and right directions.

[0355] That is, the power transmission unit 400 can be configured to reciprocally rotate at a preset angle less than one full rotation while its rotation center is fixed.

[0356] Even if the power transmission unit 400 rotates rapidly, the position of the power transmission unit 400 remains fixed.

[0357] Therefore, vibrations and noises generated by the power transmission unit 400 inside the inner housing 20 can be minimized.

[0358] Figure 14 A system in which the mobile clothes hanger operates is shown.

[0359] The clothes processing apparatus of the present invention may include a control unit C that drives one or more of the mobile clothes hanger 100, the steam generating unit 50, and the heat pump system 80 to execute any program for processing the clothes.

[0360] The control unit C can execute various programs composed of a series of control methods capable of performing renovation operations such as drying, deodorizing, sterilizing, and wrinkle-removing on the clothes.

[0361] The clothes processing apparatus of the present invention may further include an input unit I and a display unit D. The input unit I receives an instruction for the control unit C to execute the program, and the display unit D receives information from the control unit C and displays the state of the clothes processing apparatus. The input unit I and the display unit D may be provided on either the cabinet 10 or the door 11.

[0362] The control unit C can operate the mobile clothes hanger 100 when receiving an instruction to execute the program from the input unit I or the like, or when receiving an instruction to input the power supply.

[0363] The control unit C can operate the mobile clothes hanger 100 by driving the drive unit 200. The drive unit 200 can be configured to receive an instruction from the control unit C, operate the transfer unit 300, and shake the clothes.

[0364] The control unit C can be configured to provide a signal for directly driving the drive unit 200 and also receive information from the drive unit 200.

[0365] The clothes processing apparatus of the present invention may include a current detection unit 260 that receives electrical information such as output current and voltage from the drive unit 200 and transmits it to the control unit C.

[0366] In addition, the laundry treatment apparatus of the present invention may include a position sensing unit 270 that senses the position of the power transmission unit 400 or the connection unit 600 and transmits it to the control unit C. The position sensing unit 270 may be configured to sense the rotation angles of the rotary shaft 220 and the power shaft 240 or the position of the eccentric shaft 310.

[0367] The laundry treatment apparatus of the present invention may be configured to sense clothing information including any one or more of the weight, length, material, properties, and types of the clothing based on a control system for driving the mobile hanger 100. The laundry treatment apparatus of the present invention may optimize and adjust one or more of the intensity, type, time, and option values of a refresh program for treating the clothing according to the sensed clothing information.

[0368] For example, the laundry treatment apparatus of the present invention may operate by adjusting any one or more of the driving speed of the mobile hanger 100, the driving time and driving output of the steam generating unit 50, and the driving time and driving rpm (revolutions per minute) of the heat pump 80 according to the sensed clothing information.

[0369] The driving speed of the mobile hanger 100 may be defined by either the driving rpm of the driving unit 200 or the speed at which the power transmission unit 400 moves.

[0370] The driving speed of the mobile hanger 100 may be defined based on the speed at which the clothing sways or the speed at which the upper end of the clothing sways.

[0371] The laundry treatment apparatus of the present invention may differently adjust the mechanical force applied to the clothing, the amount of steam supplied to the clothing and the steam exposure time, and the temperature of the hot air supplied to the clothing and the hot air exposure time according to the sensed clothing information.

[0372] Thus, the laundry treatment apparatus of the present invention can perform matching treatment on the clothing according to the clothing information, rather than still executing a unified program regardless of the clothing information.

[0373] Of course, the laundry treatment apparatus of the present invention may have an additional sensing unit for sensing the clothing information. For example, the laundry treatment apparatus of the present invention may be configured to provide a load sensor on the mobile hanger 100 to sense the weight of the clothing, and may use a radar sensor such as light or radio waves or the position sensing unit 270 inside the inner casing to sense the length, material, type, etc. of the clothing.

[0374] However, if a plurality of sensing units for directly sensing the clothing information are provided in the clothing treatment apparatus, not only will the production and repair costs increase, but due to the characteristics of supplying hot air and steam to the interior of the clothing, it may be difficult to maintain the durability of the sensing units.

[0375] For this reason, the clothing treatment apparatus of the present invention can be configured such that the control unit C performs an operation on the electronic information applied to or output from the moving clothes hanger 100 while driving the moving clothes hanger 100.

[0376] The electronic information may include any one or more of a current value, a power value, a waveform of current or power, an amplitude, and a period applied to or output from the motor unit 210 while driving the driving unit 200.

[0377] Generally, in a washing machine and a dryer, etc., the weight of the clothing is calculated by analyzing the current value output from the driving unit that rotates the drum containing the clothing. This is because it is possible for the clothing contained in the washing machine and the dryer to form a mass inside the drum regardless of the type, material, and length of the clothing. In other words, the washing machine and the dryer can determine the current value required when the driving unit rotates or the current value output from the driving unit according to the weight of the clothing regardless of the state of the clothing, and there are almost no variables that affect the current value.

[0378] However, in the clothing treatment apparatus of the present invention such as a clothing care machine, the clothing is only placed on the upper part of the moving clothes hanger 100, and the other parts are arranged in the accommodation space 21 in an extended state. As a result, when the moving clothes hanger 100 is driven, the clothing vibrates in the height direction while forming various waveforms and vibrating.

[0379] In other words, the vibration of the clothing is independent of the vibration of the moving clothes hanger 100, and thus the vibration generated by the clothing or acts as a load on the moving clothes hanger 100.

[0380] The amplitude or vibration form generated by the clothing affects the current value and the power value applied to or output from the driving unit 200.

[0381] As a result, in the clothing treatment apparatus of the present invention, if the weight of the clothing is simply sensed only by the electronic information while driving the moving clothes hanger 100, its reliability may be significantly reduced.

[0382] For example, as the clothing is set in different lengths, even when vibrating at the same frequency, the waveforms or amplitudes of the vibrations are formed differently. Additionally, although the weights of the clothing are the same as each other, when the lengths of the clothing are different from each other, when each piece of clothing sways at the same frequency, the waveforms or amplitudes of the vibrations of each piece of clothing may also be different from each other. As a result, although the motor 210 of the driving unit 200 is driven at the same speed, if the lengths of the clothing placed on the power transmission unit 400 are different from each other, it is very likely that the control unit calculates that the weights of the clothing are different from each other.

[0383] If the mobile clothes hanger 100 is driven slowly, the upper part to the lower part of the clothing can sway integrally while moving with the mobile clothes hanger 100. However, if the mobile clothes hanger 100 is driven quickly, the upper part of the clothing starts to sway with a larger amplitude and period, but the lower part of the clothing cannot follow the vibration of the upper part of the clothing or follows late due to the inertial force, and thus situations such as twisting where the clothing bends may occur.

[0384] Furthermore, when the driving frequency of the mobile clothes hanger 100 or the power transmission unit 400 corresponds to the resonance frequency of the clothing, the vibrating area and the fixed area of the clothing can vibrate in the form of a stationary wave. If the clothing vibrates in the form of a stationary wave, the clothing transmits different inertial forces to the mobile clothes hanger 100 compared to when it does not vibrate in the form of a stationary wave, causing a large error in the electronic information of the driving unit 200.

[0385] In addition, even if the clothing forms a stationary wave and vibrates, the clothing may change the multiple (n) of the stationary wave generated in the clothing and vibrate according to the driving speed of the driving unit 200 or the power transmission unit 400. In this case, even if the clothing vibrates with the same stationary wave, other inertial forces can be provided to the mobile clothes hanger 100, thus providing an influence that causes changes in the electronic information of the driving unit 200.

[0386] In summary, when driving the mobile clothes hanger 100, the electronic information applied to the driving unit 200 and the electronic information output from the driving unit 200 are not only affected by the weight of the clothing, but also greatly affected by the vibration characteristics of the clothing. Since the vibration characteristics of the clothing depend on the driving speed of the driving unit 200 or the power transmission unit 400, it can be considered that the factors affecting the electronic information that can be sensed by the driving unit 200 are the weight of the clothing and the driving speed of the driving unit 200 or the power transmission unit 400.

[0387] Therefore, the laundry treatment apparatus of the present invention can be configured to calculate laundry information including any one or more of the weight and length of the laundry, taking into account not only the weight of the laundry but also the vibration characteristics of the laundry according to the driving speed of the driving unit 200 or the power transmission unit 400.

[0388] Figure 15 An embodiment is shown in which the control unit of the laundry treatment apparatus of the present invention accurately calculates laundry information using a moving hanger.

[0389] The laundry treatment apparatus of the present invention operates the moving hanger 100 by driving the driving unit 200 by the control unit C.

[0390] The driving unit 200 can continuously rotate the rotary shaft 220 and the power shaft 240 in one direction and shake the laundry by reciprocally moving the power transmission unit 400 through the transmission unit 300.

[0391] The reciprocating movement of the power transmission unit 400 is a concept including at least any one of linear reciprocating movement of the power transmission unit 400, reciprocating rotational movement at a preset angle, oscillator movement, and periodic movement.

[0392] In other words, regardless of what embodiment the moving hanger 100 is set to, the moving hanger 100 provided in the laundry treatment apparatus of the present invention can also control the driving unit 200 to reciprocally move the power transmission unit 400.

[0393] In the laundry treatment apparatus of the present invention, when the moving hanger 100 is driven, regardless of how the driving unit 200 and the transmission unit 300 operate, the power transmission unit 400 can also change the moving direction of the hanger unit 700 twice in each cycle.

[0394] Whenever the moving direction of the hanger unit 700 and the laundry placed on the hanger unit 700 through the hanger part 900 is changed, a corresponding inertial force is generated. Thus, the hanger unit 700 transmits the inertial force to the power transmission unit 400 twice in each reciprocating cycle.

[0395] If the hanger unit 700 reciprocates, the driving unit 200 receives not only the load for moving the power transmission unit 400 but also the inertial force. Each time the driving unit 200 periodically receives the inertial force, it bears an additional load.

[0396] As a result, while the driving unit 200 is driving, since the inertia force is generated by the clothing according to a preset cycle, the electronic information output from the driving unit 200 or the electronic information received through the driving unit 200 may include a graph capable of knowing the motion state of the hanger unit 700.

[0397] Therefore, the control unit C of the clothing processing apparatus of the present invention can calculate clothing information including the vibration characteristics of the clothing by analyzing the electronic information itself and the inertia force of the clothing that can be sensed in the electronic information.

[0398] Furthermore, the control unit C can identify the cycle of reciprocating movement of the hanger unit 700 and the time point at which the hanger unit 700 changes its moving direction by sensing the inertia force applied to the driving unit 200.

[0399] In addition, the control unit C can also sense the magnitude of the inertia force and the change in the magnitude of the inertia force to sense the motion state of the clothing.

[0400] For example, in the clothing processing apparatus of the present invention, if the control unit C receives the electronic information from the driving unit 200, the DC component (DC component) and the AC component (AC component) can be extracted from the electronic information.

[0401] The DC component, as an electric signal having an absolute value with a preset amount, includes information related to the load required when driving the driving unit 200 at a specific RPM. Since the driving unit 200 requires a greater load as the clothing is heavier, the DC component may include information reflecting the weight of the clothing. Therefore, the control unit C can analyze the DC component to obtain the information required for calculating the weight of the clothing.

[0402] The AC component, as an electric signal having a preset cycle, may include information reflecting the vibration characteristics of the clothing. During the process of the clothing vibrating or the process in which the hanger unit 700 periodically changes its moving direction, the inertia force can be transmitted to the driving unit 200, and the transmitted inertia force can be reflected as the AC component.

[0403] The control unit C can obtain the information required for calculating the vibration characteristics and vibration period of the clothing, etc. by analyzing the AC component.

[0404] In the case where the AC component has a preset cycle, the second harmonic has the clearest signal characteristics in the periodic curve, and it has reliability information related to the cycle information. Therefore, the control unit C can preferentially extract or screen the second harmonic from the sensed AC component, and perform a detailed analysis of the vibration characteristics of the clothing through the second harmonic.

[0405] Depending on the length and material of the clothing, the characteristics of the vibration of the clothing may vary. Therefore, the vibration characteristics include clothing information associated with the length and material of the clothing. Thus, the control unit C can calculate clothing information such as the length and material of the clothing by using the vibration characteristics analyzed through the AC component analysis.

[0406] Furthermore, the control unit C can additionally track and sense changes in the electronic information of the drive unit 200 by changing the drive speed of the drive unit 200 or the power transmission unit 400. Thus, it is possible to confirm the previously sensed clothing information and recalculate the clothing information.

[0407] As a result, when driving the drive unit 200, the control unit C can analyze the absolute value of the electronic information including one or more of current and voltage and the vibration characteristics of the electronic information to calculate the clothing information.

[0408] Figure 16 An embodiment of calculating the weight of clothing of the clothing treatment apparatus of the present invention is shown.

[0409] Referring to Figure 16 In the clothing treatment apparatus of the present invention, as shown in (a), the long clothing L can be arranged in the accommodation space 20 in a state of being placed on the moving hanger 100.

[0410] Referring to Figure 16 In the clothing treatment apparatus of the present invention, as shown in (b), the moving hanger 100 of the clothing treatment apparatus of the present invention can drive the drive unit 200 to reciprocate the power transmission unit 400. The hanger unit 700 is coupled to the power transmission unit 400, and the hanger unit 900 is placed on the hanger unit 700. Therefore, the clothing placed on the hanger unit 900 can reciprocate and vibrate together with the power transmission unit 400.

[0411] The moving hanger 100 can be driven at a specific frequency to shake the clothing supported by the power transmission unit 400.

[0412] The driving of the moving hanger 100 at a specific frequency means that the moving hanger 100 reciprocates periodically. That is, the driving of the moving hanger 100 at a specific frequency means that the power transmission unit 400 that actually reciprocates the clothing is driven periodically at a specific frequency. In addition, in order to drive the power transmission unit 400 at a specific frequency, the drive unit 200 is driven at a specific speed. That is, if the motor unit 210 is driven at a specific RPM, the power transmission unit 400 can be driven at a specific frequency, which can be defined as the moving hanger 100 being driven at a specific frequency.

[0413] If the mobile clothes hanger 100 starts to be driven at a low frequency, the long clothes L can reciprocate with the power transmission part 400. During this process, although the upper end of the clothes L can move with the power transmission part 400, the farther away from the power transmission part 400, the more the clothes L tends to remain stationary under the action of inertia. As a result, the lower part of the clothes will move more lagged than the upper end of the clothes, making the lower end of the clothes L move in the most lagged state among the clothes L.

[0414] In addition, when the power transmission part 400 stops to change the moving direction, although the upper end of the clothes L stops together with the power transmission part 400, the lower end of the clothes remains in a moving state under the action of inertia. As a result, the lower part of the clothes moves farther than the power transmission part 400 from the upper part to the lower part, and the lower end of the clothes moves the most.

[0415] If the mobile clothes hanger 100 or the driving part 200 is driven at a low frequency, causing the power transmission part 400 to reciprocate relatively slowly, the amplitude of the reciprocating movement of the lower end of the clothes can be greater than the amplitude of the reciprocating movement of the upper end of the clothes.

[0416] In this case, if the driving frequency of the mobile clothes hanger 100 or the driving part 200 becomes higher, the power transmission part 400 will reciprocate faster than before, and the inertial force generated by the clothes L will become larger. As a result, the displacement difference between the lower end and the upper end of the clothes may become larger.

[0417] In addition, if the power transmission part 400 moves, the inertial force generated by the whole clothes L due to the displacement difference acts as an additional load that the mobile clothes hanger 100 has to bear. In addition, the clothes load borne by the mobile clothes hanger 100 reaches the maximum value when the power transmission part 400 changes the moving direction.

[0418] Refer to Figure 16 In (c) of, if the mobile clothes hanger 100 or the driving part 200 is driven at a faster frequency, the reciprocating speed of the power transmission part 400 will become faster. At this time, the displacement difference between the upper and lower parts of the clothes will also cause the moving directions of the upper and lower parts of the clothes to be different.

[0419] In addition, the displacement gradually increases from the upper part to the lower part of the clothes. When it is coupled with the displacement of the reciprocating movement of the power transmission part 400, there will be intervals where the upper and lower parts of the clothes move in different directions from each other, and the clothes form a waveform and vibrate.

[0420] If the clothing vibrates, the vibration energy is transmitted to the moving hanger 100 and acts as an additional load applied to the driving unit 200.

[0421] In addition, if the moving hanger 100 is driven at a faster frequency, more waveforms are formed and the clothing vibrates. As a result, the clothing L does not move in the same direction as a whole, but moves in different directions from the upper part to the lower part, causing the whole clothing to vibrate.

[0422] In other words, if the driving unit 200 is driven from low speed to acceleration and driven at a specific speed or higher, the clothing L as a whole cannot move in the same direction, and the moving directions are different from each other, causing the clothing to form a twisted waveform and twist.

[0423] The twisting of the clothing L can be defined as indicating positions on the clothing L where the moving direction or the amplitude direction is different from each other.

[0424] If the driving unit 200 is driven at a speed higher than the speed at which the clothing L deforms, the clothing L forms a node n region and an antinode a region. The node n region is a region that does not vibrate at least instantaneously with respect to the moving hanger 100, and the antinode a region is a region that vibrates with the maximum amplitude along the moving direction or the opposite direction with respect to the moving hanger 100.

[0425] If the power transmission unit 400 reciprocates more quickly, more nodes n and antinodes a are formed in the clothing L.

[0426] In addition, if the moving hanger 100 is driven at the same frequency as the resonance frequency of the clothing, the clothing L can form a standing wave and vibrate or twist.

[0427] The vibration of the clothing in the form of a standing wave means that when the clothing vibrates, the position of the node n that seems to be stationary on the clothing does not change with time, and the position of the antinode a that vibrates with the maximum amplitude on the clothing also does not change with time.

[0428] The standing wave is generated whenever the moving hanger 100 is driven at n times the resonance frequency. As a result, whenever the driving unit 200 reaches a specific speed range, the clothing vibrates in the form of a standing wave, so that the positions of the region where the node n is formed and the region where the antinode a is formed on the clothing may not change.

[0429] When the vibrations occurring in the clothing cancel each other out because their amplitude directions are different from each other, not all of them may be transmitted to the moving hanger 100. If the clothing vibrates in the form of a standing wave, the vibration patterns generated in the clothing may be formed symmetrically with respect to each other along the height direction of the clothing. As a result, if the clothing vibrates in the form of a standing wave, most of the vibrations generated in the clothing can be canceled out, and the vibrations transmitted to the moving hanger 100 can be minimized to the greatest extent.

[0430] Figure 17 The change in the vibration pattern of the clothing according to the driving frequency of the moving hanger is shown.

[0431] Referring to Figure 17 In (a) of, when the moving hanger 100 is driven at a frequency below the fundamental frequency, the clothing L can move in the same direction as a whole. When the moving hanger 100 is driven at the fundamental frequency, the moving directions of the clothing L can all be the same only according to the different regional amplitudes.

[0432] The fundamental frequency can be defined as the driving frequency of the moving hanger 100 at which waveforms or vibrations start to be generated on the clothing.

[0433] If the moving hanger 100 is driven at a frequency below the fundamental frequency, waveforms will not be generated on the clothing, so the clothing as a whole can move in the same direction.

[0434] As the driving speed of the driving unit 200, the first speed can be defined as the speed at which the moving hanger 100 is driven at the fundamental frequency. When the driving unit 200 is driven from a stationary state to the first speed at which torsion starts to be generated in the clothing L, the moving direction of the clothing L as a whole can be the same.

[0435] In other words, the amplitude at the upper end of the clothing and the amplitude at the lower end of the clothing may be different, but the moving direction of the power transmission unit 400 and the moving direction of the clothing as a whole can be the same as each other.

[0436] Referring to Figure 17 In (b) of, if the moving hanger 100 is driven at a frequency above the fundamental frequency, torsion can be generated in the clothing L. In addition, if the moving hanger 100 is driven at a resonance frequency faster than the fundamental frequency, the clothing L can vibrate in the form of a standing wave.

[0437] Whenever it is n times the minimum resonance frequency, the clothing can form a standing wave and vibrate. Therefore, the minimum frequency at which the moving hanger 100 can first make the clothing vibrate in the form of a standing wave can be defined as the minimum resonance frequency.

[0438] When the mobile clothes hanger 100 is driven at the minimum resonance frequency, the driving speed of the driving unit 200 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 resonance speed.

[0439] If the driving unit 200 is driven at a speed higher than the first speed, the clothing L can be twisted. As a result, different regions with different vibration directions can be formed in the height direction of the clothing L.

[0440] If the driving unit 200 is driven at the second speed, the reciprocating period of the mobile clothes hanger 100 can correspond to the reciprocal of the resonance frequency of the clothing L, and the clothing L can vibrate in the form of a standing wave.

[0441] If the clothing L vibrates in the form of a standing wave, the position of the node n, which is the region where the clothing L does not vibrate, is fixed, and the position of the antinode a, which is the region with the maximum amplitude, is also fixed.

[0442] When the driving unit 200 is driven at the second speed and a first-order standing wave is generated in the clothing L, there is one node n formed, and the antinode a can be formed to be one more than the node n including the upper end of the clothing.

[0443] In other words, if the driving unit 200 is driven at the second speed, the clothing can shake at the first resonance frequency f1 and vibrate in the form of a first-order (n = 1) standing wave.

[0444] The resonance frequency at which the clothing L vibrates in the form of a standing wave can be determined according to the inherent characteristics of the clothing.

[0445]

[0446] The formula (1) represents the resonance frequency of the mobile clothes hanger 100 that can cause the clothing L to form a standing wave and vibrate.

[0447] The resonance frequency (f) can be equivalent to the reciprocal of the vibration period (T) of the mobile clothes hanger 100 or the reciprocal of the reciprocating period (T).

[0448] In the formula (1), v is related to the tension and linear density of the clothing and can be determined by the fiber characteristics of each clothing, and l represents the length of the clothing.

[0449] As a result, the resonance frequency (f) at which a standing wave is generated in the clothing L can be set differently according to the length (l) of the clothing. The longer the length (l) of the clothing, the smaller the resonance frequency (f).

[0450] Refer to Figure 17In (c) above, the mobile clothes hanger 100 can be driven at a frequency up to twice the minimum resonance frequency.

[0451] As a result, the driving speed of the driving unit 200 is increased to twice, and the vibration period of the power transmission unit 400 is reduced to half. As a result, the clothes can form a standing wave of f2 equivalent to twice the first resonance frequency and vibrate.

[0452] When the mobile clothes hanger 100 is driven at twice the minimum resonance frequency (n = 2), the driving speed of the driving unit 200 can be defined as the third speed.

[0453] That is, the clothes L can vibrate in the form of a second-order standing wave (n = 2), and in the second-order standing wave (n = 2), there are two nodes n and three antinodes a on the clothes L.

[0454] When the clothes L vibrates in the form of a second-order standing wave (n = 2), the positions of the nodes n and the antinodes a generated are different from the positions of the nodes n and the antinodes a generated when the clothes L vibrates in the form of a first-order standing wave (n = 1).

[0455] Therefore, if the driving frequency of the mobile clothes hanger 100 is determined to be a multiple of the resonance frequency, it can be controlled so that the regions where the clothes generate the maximum amplitude are different.

[0456] Utilizing this, the clothes processing device of the present invention can concentrate the energy generated in the mobile clothes hanger 100 on a specific region of the clothes. In addition, the mobile clothes hanger 100 can switch the specific region of the clothes and perform concentrated vibration by changing the frequency. Thus, the clothes processing device of the present invention can shake off dust or foreign objects attached to the clothes more powerfully.

[0457] Refer to Figure 17 In (d) above, the mobile clothes hanger 100 can be driven at a frequency up to three times the minimum resonance frequency.

[0458] When the mobile clothes hanger 100 is driven at three times the minimum resonance frequency, the driving speed of the driving unit can be defined as the fourth speed.

[0459] The driving unit 200 can be driven at a speed up to three times the second speed when the clothes vibrate in the form of a first-order standing wave, and the period of the power transmission unit 400 can be shortened to 1 / 3.

[0460] As a result, the clothing vibrates at a resonance frequency of f3, forming a third-order standing wave (n = 3) and vibrating, such that three nodes n and four antinodes a can be formed in the clothing L. When the clothing L vibrates in the form of a third-order standing wave (n = 3), the positions where the nodes n and the antinodes a are generated are different from those when the clothing L vibrates in the form of a first-order standing wave (n = 1) and when the clothing L vibrates in the form of a second-order standing wave (n = 2). Additionally, the interval between the nodes n is shorter than before.

[0461] However, the amplitude of the antinode a can be the same as when the moving hanger 100 is driven at the minimum resonance frequency or up to twice the minimum resonance frequency.

[0462] The clothing treatment device of the present invention can set more regions where the clothing vibrates and vibrate them uniformly, or set fewer regions where the clothing vibrates and vibrate them concentratedly by adjusting the frequency of the moving hanger 100.

[0463] Refer to Figure 17 In (e) of, if the moving hanger 100 is driven at a speed up to four times the minimum resonance frequency and the driving unit 200 is driven at a speed up to four times the second speed when the clothing vibrates in the form of a first-order standing wave, the reciprocating period of the power transmission unit 400 is shortened to 1 / 4.

[0464] When the moving hanger 100 is driven at four times the minimum resonance frequency, the driving speed of the driving unit can be defined as the fifth speed.

[0465] In this way, when the moving hanger 100 is driven at k times the minimum resonance frequency (n = k), the driving speed of the driving unit 200 can be defined as the (k + 1)th speed.

[0466] As a result, the clothing vibrates in a state of a resonance frequency of f4, and the clothing L vibrates in the form of a fourth-order standing wave (n = 4). The clothing L can vibrate to form four nodes n and five antinodes a. When the clothing L vibrates in the form of a fourth-order standing wave (n = 4), the positions where the nodes n and the antinodes a are generated are different from those when the clothing L vibrates in the form of a first-order standing wave (n = 1), when the clothing L vibrates in the form of a second-order standing wave (n = 2), and when the clothing L vibrates in the form of a third-order standing wave (n = 3).

[0467] Additionally, the interval between the nodes n can be shorter than before. If the amplitude of the power transmission unit 400 is the same, the amplitude of the antinode a can be formed to be the same.

[0468] If the driving unit 200 drives faster, the intervals of the plural nodes n formed in the clothing can be shortened, and the formation positions of the plural nodes n can also be different.

[0469] As described above, if the moving clothes hanger 100 vibrates at n times the minimum resonance frequency, or the driving unit 200 vibrates at n times the second speed equivalent to the minimum resonance speed, the clothing L can vibrate in the form of a standing wave proportional to the n multiple.

[0470] According to Equation (1), the resonance frequency at which the clothing vibrates in the form of a standing wave varies according to the length of the clothing. In addition, the driving speed or driving RPM of the driving unit 200 that enables the clothing to vibrate in the form of a standing wave is also determined as a unique value (characteristic value) for each piece of clothing.

[0471] On the other hand, the clothing processing apparatus of the present invention can be set to distinguish whether the clothing vibrates irregularly or vibrates in a manner that forms a standing wave.

[0472] When the driving frequency of the moving clothes hanger 100 is increased, if the driving frequency coincides with the resonance frequency of the clothes placed thereon, the vibration characteristics of the clothing are different from those when no standing wave is formed.

[0473] In other words, when the clothing does not vibrate in the form of a standing wave, the change in its vibration is linear or the amount of change in vibration is predictable. However, when the clothing vibrates in the form of a standing wave, its vibration characteristics are different from those when vibrating at the previous frequency and those when vibrating at the subsequent frequency, and a sharp change occurs.

[0474] Utilizing this characteristic, the control unit C can detect that the frequency corresponding to the moving clothes hanger 100 is the resonance frequency of the clothes placed thereon through a sharp change in the current value or power value output or applied from the motor unit 210 of the driving unit 200.

[0475] For example, when the clothing vibrates at the resonance frequency, the current value or power value sensed by the driving unit 200 may instantaneously reach a peak.

[0476] Alternatively, when the clothing vibrates in the form of a standing wave, its vibration may be significantly reduced compared to when it does not vibrate in the form of a standing wave, and less vibration may be transmitted to the moving clothes hanger 100. Thus, the control unit C can detect that the corresponding frequency is the resonance frequency of the clothes placed thereon through a sharp decrease in the load applied to the driving unit 200.

[0477] Or, the control unit C can utilize Figure 15The method described senses whether the frequency of the mobile clothes hanger 100 is equivalent to the resonance frequency of the clothes. The control unit C can analyze the characteristics of the second harmonic in the electronic information including the current value or power value of the drive unit 200 to sense in real time whether the clothes are vibrating at the resonance frequency. For example, the control unit C can sense that the frequency of the mobile clothes hanger 100 is the resonance frequency of the clothes placed thereon through the generation of a singularity point where at least any one of the waveform, amplitude, and period of the second harmonic changes sharply.

[0478] In addition, when the clothes vibrate at the resonance frequency, the control unit C can grasp the change in the driving speed of the drive unit 200 to sense whether the clothes are vibrating at the resonance frequency. For example, the control unit C can grasp the resonance frequency of the clothes by sensing the temporary change in the driving speed of the drive unit 200 when the clothes vibrate at the resonance frequency and when the clothes vibrate at a frequency different from the resonance frequency.

[0479] In addition, the control unit C can sense the resonance frequency through a temporary change in the inertial force transmitted to the mobile clothes hanger 100 when vibrating at the resonance frequency.

[0480] In addition, even if the clothes do not actually vibrate at the resonance frequency, the control unit C can immediately infer the resonance frequency of the clothes by matching the second harmonic output from the drive unit 200 when the clothes vibrate with a pre-stored table or data.

[0481] In addition, the control unit C can confirm whether the sensed resonance frequency is equivalent to the actual resonance frequency. For example, when the mobile clothes hanger 100 is driven at a frequency that is a multiple of the sensed resonance frequency, the control unit C can confirm whether the changes sensed by the above method are periodically displayed.

[0482] As a result, the control unit C can calculate and sense one or more of the resonance frequency of the clothes, the driving speed of the drive unit 200 for vibrating the clothes at the resonance frequency, the RPM of the drive unit 200, and the reciprocating period of the power transmission unit 400 through the mobile clothes hanger 100.

[0483] Hereinafter, an embodiment of a control method for accurately sensing the weight of the clothes using the vibration characteristics of the clothes of the present invention will be described.

[0484] On the other hand, if the clothes L vibrate and nodes n are formed on the clothes, the vibration generated at a position closer to the lower part than the nodes n may not be completely transmitted to the mobile clothes hanger 100.

[0485] Additionally, if the clothing L vibrates in the form of a standing wave, the position of the node n is always fixed. Therefore, the vibration generated in the clothing L may be blocked by the node n and may not be completely transmitted to the mobile hanger 100.

[0486] Furthermore, as the clothing L vibrates in the form of a standing wave with a greater multiple, the interval between the node n and the node n becomes shorter and shorter, making the total amount of vibration energy of the clothing remaining between each node smaller. As a result, the position of the node closest to the mobile hanger 100 will also gradually approach the mobile hanger 100 as the clothing vibrates in the form of a greater standing wave, thereby transmitting less vibration or inertial force to the mobile hanger 100.

[0487] In summary, even if the weight of the clothing is the same, the vibration energy or inertial force transmitted from the clothing L to the mobile hanger 100 will vary depending on the position of the node n generated in the clothing L, the interval between the node n adjacent to the mobile hanger 100 and the mobile hanger 100, and whether the clothing L vibrates in the form of a standing wave or in an arbitrary waveform. Therefore, in order to accurately and consistently calculate the weight of the clothing placed on the mobile hanger 100, the clothing treatment device of the present invention needs to minimize or block the vibration generated in the clothing.

[0488] To this end, the clothing treatment device of the present invention can be set to calculate the weight of the clothing while driving the mobile hanger 100 at a frequency lower than the resonance frequency at which a standing wave is generated in the clothing.

[0489] Additionally, the clothing treatment device of the present invention can be set to calculate the weight of the clothing while driving the mobile hanger 100 at a frequency lower than the fundamental frequency (period) at which the clothing begins to generate a waveform or vibration.

[0490] That is, the clothing treatment device of the present invention can be set to drive the driving unit 200 within a range below the speed at which the clothing vibrates in the form of a standing wave when calculating the weight of the clothing placed on the mobile hanger 100.

[0491] The clothing treatment device of the present invention can calculate the weight of the clothing by driving the driving unit 200 within a speed range below the second speed of the minimum resonance speed.

[0492] Specifically, the control unit C of the clothing treatment device of the present invention can sense the weight of the clothing through the electronic information applied or output to the driving unit 200 while increasing the driving frequency of the mobile hanger 100 in the interval from the speed at which the mobile hanger 100 is stationary to the second speed.

[0493] In addition, in order to minimize the influence of the vibration of the clothing on the driving unit 200 and eliminate the influence of the node n generated when the clothing twists and vibrates, the control unit C can drive the driving unit 200 in the range below the first speed and sense the weight of the clothing.

[0494] That is, the control unit C can drive the mobile clothes hanger 100 in the speed range below the speed before the clothing is about to twist, eliminate the influence of the vibration of the clothing on the driving unit 200, and thus can analyze the load applied to the driving unit 200 to calculate the weight of the clothing.

[0495] The control unit C can calculate the weight of the clothing through the driving of the driving unit 200. It can directly adopt the method of using a motor to rotate a drum in existing washing machines, dryers, etc., or can directly adopt the method Figure 15 described in.

[0496] As a result, the clothing treatment device of the present invention can accurately sense the weight of the clothing. In addition, after sensing the weight of the clothing, the clothing treatment device of the present invention drives the mechanical chamber to supply the steam or the hot air to the clothing. That is, one or more of the steam and hot air supplied to the clothing can be set differently according to the sensed weight of the clothing, and the driving frequency of the mobile clothes hanger 100 can also be controlled differently.

[0497] For example, when the clothing treatment device of the present invention senses the weight of the clothing, it drives the mobile clothes hanger 100 at a frequency below the basic frequency, but when executing any program for treating the clothing, it can drive the mobile clothes hanger 100 at a frequency greater than the basic frequency. Thus, the clothing treatment device of the present invention can transfer more physical force to the clothing when treating the clothing, so as to shake off more foreign matters from the clothing or be more evenly exposed to the supplied steam and hot air.

[0498] The clothing treatment device of the present invention can set the maximum frequency of driving the mobile clothes hanger 100 differently according to the weight of the clothing. The clothing treatment device of the present invention can control the maximum frequency of driving the mobile clothes hanger 100 differently according to the weight of the clothing when supplying one or more of the steam and the hot air to the inner housing 20.

[0499] For example, even if the mobile clothes hanger 100 is driven at the same frequency, more vibrations may occur as the weight of the clothing is heavier. Therefore, the maximum frequency of driving the mobile clothes hanger 100 can be set lower as the weight of the clothing is heavier.

[0500] For example, if the clothing is heavier, more hot air or steam needs to be supplied to the clothing to complete the drying, deodorizing, sterilizing, dehumidifying, etc. of the clothing. Therefore, the clothing treatment apparatus of the present invention can control the steam generating unit 50 so that when the weight of the clothing is sensed to be heavier, the injection amount of the steam supplied to the inner casing is larger than when the weight of the clothing is sensed to be lighter, or the injection time of the steam is longer than when the weight of the clothing is sensed to be lighter. In addition, the clothing treatment apparatus of the present invention can control the compressor 83 and the air supply fan so that when the weight of the clothing is heavier, the supply amount of the hot air is larger than when the weight of the clothing is lighter, or the supply time of the hot air is longer than when the weight of the clothing is lighter.

[0501] Figure 18 An embodiment in which the clothing treatment apparatus of the present invention controls the moving hanger by sensing the weight and resonance frequency of the clothing is shown.

[0502] The clothing treatment apparatus of the present invention can determine an optimum frequency (Optimum Hz) that can drive the moving hanger 100 in an optimal manner according to the weight of the clothing. The optimum frequency (Optimum Hz) can be determined as the frequency that minimizes the vibration generated by the clothing. In addition, the optimum frequency (Optimum Hz) can be determined as the maximum frequency at which the clothing can vibrate without exceeding the limit vibration that allows the vibration to radiate to the outside of the cabinet 10.

[0503] Therefore, the clothing treatment apparatus of the present invention drives the moving hanger 100 at the optimum frequency (Optimum Hz), so that while reducing the vibration generated in the clothing treatment apparatus, sufficient physical force can be applied to the clothing.

[0504] On the other hand, as described above, when the clothing is driven at the resonance frequency, it vibrates in a manner in which the antinodes and nodes are fixed, so that a specific area of the clothing can be concentrated, and the vibration or inertial force transmitted from the clothing can be minimized.

[0505] Therefore, the clothing treatment apparatus of the present invention can drive the moving hanger at the resonance frequency at which the clothing vibrates in the form of a standing wave in at least a part of the interval during the execution of any program for treating the clothing.

[0506] That is, although the clothing treatment apparatus of the present invention drives at the optimum frequency (Optimum Hz) corresponding to the weight of the clothing, in at least a part of the interval, the moving hanger 100 can be driven at the resonance frequency so that the clothing vibrates in the form of a standing wave. Thereby, while minimizing the vibration generated in the clothing, a concentrated physical force can be transmitted to a specific area of the clothing.

[0507] In addition, the laundry treating apparatus of the present invention can drive the moving hanger 100 at two or more resonance frequencies so that the laundry vibrates in the form of two or more standing waves. Thereby, the region where the laundry vibrates intensively is changed, so that a concentrated physical force can be sequentially applied to the entire laundry. Therefore, the foreign matter removal effect of the laundry and the exposure effect of steam and hot air can be maximized.

[0508] In addition, the control unit C can drive the moving hanger 100 repeatedly at the optimal frequency and the resonance frequency. Thereby, while minimizing the vibration transmitted to the cabinet 10, a specific area of the laundry can be shaken intensively.

[0509] In addition, the control unit C can drive the moving hanger 100 at a first resonance frequency that causes the laundry to vibrate in the form of a standing wave within a first time period, and can drive the moving hanger 100 at a second resonance frequency that causes the laundry to vibrate in another standing wave form within a second time period. The control unit C can also completely omit driving the moving hanger 100 at the optimal frequency.

[0510] The first time period and the second time period can be the same as each other.

[0511] In addition, the first time period can also be different from the second time period. For example, the first time period can be set to be shorter than the second time period.

[0512] In addition, the control unit C can drive the moving hanger 100 at a first resonance frequency that causes the laundry to vibrate in the form of a standing wave within a first time period, can drive the moving hanger 100 at a second resonance frequency that causes the laundry to vibrate in another standing wave form within a second time period, and can drive the moving hanger 100 at the optimal frequency within a third time period.

[0513] Here, the first resonance frequency, as a frequency capable of driving the laundry at the resonance frequency, can be any frequency that is n times the minimum resonance frequency.

[0514] In addition, the second resonance frequency, as another frequency capable of driving the laundry at the resonance frequency, can be any frequency that is (n + 1) times the minimum resonance frequency.

[0515] Specifically, the control unit C determines the optimal frequency for driving the moving hanger according to the sensed weight of the laundry, and during the execution of the program, the moving hanger 100 can also be driven at a resonance frequency closest to the optimal frequency in at least a part of the interval.

[0516] That is, even when the control unit C drives the mobile clothes hanger 100 at the resonance frequency, it can drive the mobile clothes hanger 100 at the resonance frequency closest to the optimum frequency, suppressing the vibration transmitted from the clothes to the maximum extent and shaking the clothes stably.

[0517] Refer to Figure 18 In (a) of, as the driving frequency of the mobile clothes hanger 100 changes, the positions of the nodes n and antinodes a formed in the clothes L also change.

[0518] The control unit can drive the mobile clothes hanger 100 at a resonance frequency (High Hz) higher than the optimum frequency (Optimum Hz) and at a resonance frequency (Low Hz) lower than the optimum frequency in at least a part of the interval during the execution of the program.

[0519] The control unit can repeatedly drive the mobile clothes hanger 100 at a resonance frequency (High Hz) higher than the optimum frequency (Optimum Hz) for a preset time and drive the mobile clothes hanger 100 at a resonance frequency (Low Hz) lower than the optimum frequency for a preset time.

[0520] The control unit C can drive the mobile clothes hanger 100 at a high resonance frequency (High Hz), then drive the mobile clothes hanger 100 at the optimum frequency, and then drive the mobile clothes hanger 100 at a low resonance frequency (Low Hz), and repeat this process.

[0521] Refer to Figure 18 In (b) of, if the mobile clothes hanger 100 is driven at a resonance frequency (Hihg Hz) higher than the optimum frequency, the clothes can vibrate as shown in the right figure. If the mobile clothes hanger 100 is driven at a resonance frequency (Low Hz) lower than the optimum frequency, the clothes can vibrate as shown in the left figure.

[0522] Using this, the control unit C can repeatedly perform the following process: drive the driving unit 200 for a preset time to make the clothes vibrate in the left form, then increase the driving speed of the driving unit 200 to make the clothes vibrate in the right form for a preset time, and then reduce the driving speed of the driving unit 200 again to make the clothes vibrate in the left form.

[0523] In this way, the control unit C can change the position of the antinode a formed in the clothes by changing the driving speed or driving period of the mobile clothes hanger 100, so as to be able to appropriately distribute the dust removal force on the clothes. After changing the positions of the nodes n and antinodes a formed in the clothes L, the control unit C can fix the positions of the nodes n and antinodes a again, so as to be able to concentrate and separate foreign matters in other areas again.

[0524] The time during which the driving unit 200 is driven at various multiples of the second speed can be set to be longer than the time during which the driving unit 200 accelerates or decelerates.

[0525] Figure 18 (b) of shows that the control unit C accelerates or decelerates the mobile clothes hanger 100 at two resonance frequencies, but this is only an embodiment, and the control unit C can drive the mobile clothes hanger 100 at three or four or more resonance frequencies to accelerate and decelerate it step by step.

[0526] On the other hand, the control unit C can actively utilize the characteristic that, when driven at the resonance frequency, the vibration transmitted from the clothes is minimized.

[0527] For example, during the period when the clothes are vibrated at a frequency other than the resonance frequency, when the clothes generate excessive vibration, the control unit C can drive the mobile clothes hanger 100 at a frequency equivalent to the resonance frequency to suppress the vibration of the clothes L.

[0528] For example, during the period when the clothes are driven at the optimal frequency, when the clothes generate excessive vibration, the control unit C can drive the mobile clothes hanger 100 at a frequency equivalent to the resonance frequency to suppress the vibration of the clothes L.

[0529] Figure 19 shows the process of the clothes processing device of the present invention sensing the weight of the clothes through the mobile clothes hanger.

[0530] The clothes processing device of the present invention can provide a control method including a sensing step A of sensing clothes information when a power supply instruction for supplying power to the control unit C is input through the input unit I or an execution instruction for the control unit C to execute any program is input or when it is sensed that the door 12 opens and closes the accommodation space 21 and is closed, and a driving step S of driving the machine room 30 to process the clothes.

[0531] The sensing step A may include a weight sensing step A1 of sensing the weight of the clothes, and the weight sensing step A1 may include a step of calculating the weight of the clothes by the control unit C while driving the mobile clothes hanger 100 and using the electronic information applied to or output from the mobile clothes hanger 100.

[0532] In the weight sensing step A1, the control unit C can sense the weight of the clothes while driving the driving unit 200 at a first speed V1 within a first time t1.

[0533] The first speed V1 in the driving speed of the driving unit 200 can be defined as the speed at which the clothing does not twist, and the second speed V2 can be defined as the minimum speed at which the clothing vibrates at the resonance frequency.

[0534] The first speed V1 can be the minimum speed at which the clothing will definitely not twist.

[0535] The control unit 100 can sense the weight of the clothing by analyzing the electronic information of the driving unit 200 while driving the driving unit 200 at a constant speed of the first speed V1. Since in the electronic information, errors associated with the vibration of the clothing L are maximally excluded, the control unit C can accurately calculate the weight of the clothing only through the driving of the mobile hanger 100.

[0536] The sensing step A can include an acceleration step A2 capable of sensing the resonance frequency of the clothing.

[0537] In the acceleration step A2, the control unit C can sense the clothing vibrating in the form of a standing wave by increasing the speed of the mobile hanger 100 to above the second speed. Since the second speed is the speed at which the clothing first vibrates in the form of a standing wave, the acceleration step A2 can be regarded as the step for the control unit C to sense the second speed, and can be regarded as the step for sensing the minimum speed of the driving unit 200 that drives the clothing in the form of a standing wave.

[0538] In the acceleration step A2, the control unit C can increase the driving speed of the driving unit 200 to a multiple of the second speed to sense and confirm the resonance frequency of the clothing.

[0539] On the other hand, in the driving step S, the control unit C can drive the driving unit 200 at a processing speed faster than the first speed and the second speed. Therefore, the sensing step A can be a step of driving the mobile hanger 100 at a lower speed than the driving step B for a preset time.

[0540] In addition, since the driving step S is executed using the information sensed in the sensing step A, the control unit C can differently set one or more of the driving speed, driving period, driving frequency, and driving RPM of the mobile hanger 100 driven in the driving step S according to the clothing information sensed in the sensing step A.

[0541] For example, in the driving step B, the speed of the driving unit 200 can be gradually accelerated or decelerated in a region corresponding to a multiple of the resonance frequency (f), and the acceleration and deceleration can be repeated.

[0542] For example, in the driving step S, the control unit C may drive the driving unit 200 at the highest speed and then decelerate to drive the driving unit 200 at the (K + 1)th speed at which the Kth order standing wave occurs in the clothing. K may be any natural number. That is, the control unit C may arbitrarily change the value of k and drive the clothing L at various resonance frequencies.

[0543] For example, the control unit C may re-increase the driving speed of the driving unit 200, drive the driving unit 200 at the highest speed, and then decelerate the driving speed of the driving unit 200 to the third speed at which the second-order standing wave is generated to drive the driving unit 200, and then decelerate to drive the driving unit 200 at the second speed at which the first-order standing wave is generated in the clothing.

[0544] Figure 20 Another embodiment showing the process of the clothing treatment apparatus of the present invention sensing the weight of the clothing by moving the hanger is shown.

[0545] Although the first speed is the speed at which the clothing does not twist, it may be set differently depending on the material or length of the clothing. Therefore, it may be difficult for the control unit C to confirm whether the speed set by the driving unit 200 in the weight sensing step A1 is the first speed of the clothing.

[0546] Therefore, if the clothing treatment apparatus of the present invention executes the weight sensing step A1, it can slowly accelerate from the state where the driving unit 200 is stationary to sense the interval corresponding to the first speed.

[0547] The control unit C may drive the driving unit 200 so that the clothing accelerates from a stationary state to a speed at which it twists or a speed at which the clothing vibrates in a standing wave form.

[0548] During the process of increasing the driving speed of the driving unit 200, if the control unit C senses that the clothing twists or the clothing vibrates in a standing wave form, it may define the speed below that as the first speed.

[0549] In addition, the control unit C may go through the following steps: during the process of increasing the driving speed of the driving unit 200, when it senses that the clothing twists or the clothing vibrates in a standing wave form, after storing the speed, it reduces the driving speed of the driving unit 200 and then accelerates again to confirm whether the stored corresponding speed is the speed at which the clothing twists or the clothing vibrates in a standing wave form.

[0550] Through this process, the control unit C can not only confirm the first speed but also confirm the second speed, and can calculate the weight of the clothing by analyzing the electronic information of the driving unit 200 when accelerating to the first speed.

[0551] Alternatively, the control unit C may redrive the mobile clothes hanger 100 at a speed equal to or lower than the first speed V1, and analyze the electronic information of the driving unit 200 to calculate the weight of the clothes.

[0552] In addition, the control unit C may increase the driving speed of the driving unit 200 to a second speed V2 or higher in the acceleration step A2 to check whether the second speed V2 is the minimum resonance speed at which the clothes vibrate in the form of a standing wave.

[0553] For example, in the acceleration step A2, the control unit C may sense the resonance frequency of the clothes by checking whether the clothes L vibrate in the form of a (k - 1)-order standing wave at the second speed V2 and a speed (Vk) corresponding to a k-fold multiple of the second speed. K may be any natural number.

[0554] If the driving step S is performed after the sensing step A, the control unit C may accelerate the driving unit 200 to the maximum speed (Vmax) to shake the clothes, and then decelerate or accelerate to a speed range corresponding to a multiple of the second speed, so as to periodically and intensively shake a specific area of the clothes.

[0555] To prevent the driving unit 200 from being overloaded, the driving speed of the driving unit 200 may be periodically reduced in the driving step S within a range of a third speed, a fourth speed, an nth speed, etc. corresponding to a multiple of the second speed.

[0556] Figure 21 FIG. is a diagram for explaining the principle by which the clothes processing apparatus of the present invention can sense the length of the clothes.

[0557] Figure 21 (a) of FIG. shows that when the long clothes L are placed on the mobile clothes hanger 100, the driving unit 200 is driven at a specific speed greater than the second speed V2. Figure 21 (b) of FIG. shows that when the clothes L shorter than the long clothes L are placed on the mobile clothes hanger 100, the driving unit 200 is driven at the same specific speed as when the long clothes L are placed on the mobile clothes hanger 100.

[0558] According to Equation (1), the resonance frequency is inversely proportional to the length of the clothes. Therefore, the short clothes L have a resonance frequency higher than that of the long clothes L, and the mobile clothes hanger 100 needs to be driven at a faster speed to form a standing wave of the same order for the short clothes L.

[0559] Refer to Figure 21(a), the specific speed may be four times the second speed or the minimum resonance speed based on the long clothing L. Therefore, the long clothing L can vibrate to form the fourth-order standing wave.

[0560] Referring to Figure 21 (b), when the short clothing L is placed, the driving unit 200 can also be driven at the same speed. In other words, Figure 21 in (b), the driving unit 200 can also be driven at a driving speed capable of forming a fourth-order standing wave in the long clothing L.

[0561] In the case of the short clothing L, the driving speed may be the driving speed at which a second-order standing wave is formed in the short clothing. That is, in the case of the short clothing L, since the length of the clothing is greater than that of the long clothing L, it has a different resonance frequency from the long clothing L.

[0562] The clothing processing device of the present invention can also utilize the property that the clothing has different resonance frequencies according to the length, and drive the moving hanger 100 to sense the length of the clothing.

[0563] Figure 22 An embodiment is shown in which the clothing processing device of the present invention senses not only the weight of the clothing but also the length.

[0564] The control method of the clothing processing device of the present invention may include a length sensing step A2 of also sensing the length of the clothing in the sensing step A. That is, the acceleration step A2 can be regarded as including the length sensing step A2.

[0565]

[0566] Referring to Equation (1) described above, the resonance frequency (fn) that causes the clothing to vibrate in the form of a standing wave is inversely proportional to the length of the clothing. However, even if the resonance frequency (fn) can be known, there is a limitation that if the v value of Equation (1) cannot be accurately known, the length (l) of the clothing cannot be accurately sensed.

[0567]

[0568] Referring to Equation (2), the v is the square root value of the value obtained by dividing the tension (T) of the clothing by the linear density (m), and the tension of the clothing is equivalent to the weight of the clothing.

[0569] In the case of the same clothing, the linear density (m) is a constant value. Therefore, if the control unit C senses the weight and the resonance frequency (fn) of the clothing, the length (l) of the clothing can be grasped.

[0570] To this end, in the weight sensing step A1, the control unit C can directly calculate the weight of the clothing through the electronic information of the driving unit 200, and in the length sensing step A2, while changing the driving speed of the driving unit 200, sense one or more resonance frequencies that can make the clothing vibrate in the form of a standing wave, and can calculate the length of the clothing using the weight of the clothing and the resonance frequency.

[0571] In the case where the control unit C cannot specifically sense or calculate the linear density (m), the control unit C can also sense two or more resonance frequencies that can make the clothing vibrate in the form of a standing wave, and thereby calculate the length (l) of the clothing.

[0572] In addition, the control unit C can also sense the resonance frequency that can make the clothing vibrate in the form of a standing wave through the moving clothes hanger 100, and when changing the driving frequency of the moving clothes hanger 100, calculate the length (l) of the clothing through the electronic information output from the driving unit 200.

[0573] As a result, the control unit C can calculate the weight of the clothing by driving the driving unit 200 in a speed range lower than the second speed V2 at which the clothing first vibrates at the resonance frequency, and can calculate the length of the clothing by driving the driving unit 200 in a speed range above the second speed at which the clothing first vibrates at the resonance frequency.

[0574] The speed range lower than the second speed may include the first speed, and the driving unit 200 can drive at a speed faster than the second speed in the driving range s.

[0575] Refer to Figure 22 , the control unit C can execute the sensing step A of sensing the clothing information.

[0576] In the sensing step A, the control unit C can drive the driving unit 200 at the first speed V1 within the first time t1, and at the same time, execute the weight sensing step A1 of calculating the weight of the clothing through the electronic information including the current applied to or output from the driving unit 200.

[0577] When the weight sensing step A1 ends, the control unit C can execute the length sensing step A2 of sensing the length of the clothing in the sensing step A.

[0578] The length sensing step A2 can be executed in a speed range faster than the weight sensing step A1, and can be executed in a speed range including the second speed or the resonance speed V2 at which the first resonance frequency is generated.

[0579] In addition, the length sensing step A2 can be performed within the second time t2. The driving unit 200 is driven at the resonance speed v2 and a speed faster than the resonance speed v2 to calculate the length of the clothing. Therefore, the second time t2 can be set to be longer than the first time t1.

[0580] On the other hand, the control unit C can periodically increase the speed of the driving unit 200 within the second time and obtain information for calculating the length (l) of the clothing.

[0581] For example, the control unit C can drive the mobile hanger 100 at a second speed or a resonance speed, which is the minimum driving speed for vibrating the clothing in the form of a standing wave, within the 2-1 time t21 and sense the minimum resonance frequency.

[0582] In addition, the control unit C can further increase the driving speed of the driving unit 200 until the clothing vibrates in the form of a standing wave. In the case where the clothing vibrates in the form of a standing wave again, the mobile hanger 100 is driven within the 2-2 time t22 to sense other resonance frequencies. Within the 2-2 time t22, the mobile hanger 100 can be driven at a speed twice that of the second speed.

[0583] The control unit C can further increase the driving speed of the driving unit 200 until the clothing vibrates in the form of a standing wave again. This process can be repeated K times. In the case where the clothing vibrates in the form of a standing wave again, the mobile hanger 100 can be driven at a speed K times that of the second speed within the 2-k time to sense the resonance frequency of the clothing.

[0584] As a result, the control unit C can accelerate the driving speed of the driving unit 200 to the interval where the clothing is driven at the resonance frequency. If the clothing is driven at the resonance frequency, the driving speed of the driving unit 200 is maintained and the electronic information of the driving unit 200 is stored. When the control unit C can obtain the electronic information of the driving unit 200 in various resonance speed intervals, the length of the clothing can be calculated based on one or more of the electronic information and the weight of the clothing.

[0585] If one or more of the length of the clothing and the weight of the clothing are sensed, the control unit C can optimize and execute the driving step S based on the clothing information.

[0586] The driving step S can drive the mobile hanger 100 within the third time t3, and the third time can be set to be longer than the first time t1 and the second time t2.

[0587] In the driving step S, the moving clothes hanger 100 can be driven at a speed faster than the driving speed of the moving clothes hanger 100 in the sensing step A.

[0588] For example, in the driving step S, the moving clothes hanger 100 can be driven at the maximum speed Vmax, or can be driven in a speed range including the second speed but faster than the second speed, or can linearly or stepwise change in a speed range where the driving speed is faster than the second speed.

[0589] Figure 23 An embodiment of the control method of the clothes processing apparatus of the present invention is shown.

[0590] The control method of the clothes processing apparatus of the present invention may include a sensing step A of sensing clothes information and a driving step S of processing the clothes.

[0591] The sensing step A and the driving step S may be executed in sequence, but the sensing step A may also be executed during the execution of the driving step S. That is, since the moving clothes hanger 100 is not always driven in the driving step S, the sensing step A can be executed at any time before the moving clothes hanger 100 is driven in the driving step S.

[0592] In the clothes processing apparatus of the present invention, if an instruction to execute any program is input through the input unit I, the driving step S can be executed.

[0593] The driving step S may include: a heating step S1 of driving the steam generating unit 50 to heat the water contained in the steam generator 51; a steam step S2 of supplying steam to the accommodation space 21 if the water in the steam generator 51 boils to generate steam; a standby step S3 of interrupting the driving of the steam generator 51 if the steam has been ejected by a set amount or for a set time; a cooling step S4 of only driving the air supply fan to cool the clothes while cooling the air in the accommodation space 21 to improve the efficiency (COP) of the heat pump system; and a drying step S5 of driving the compressor 83 and the air supply fan to supply hot air to the accommodation space 21.

[0594] On the other hand, it is preferable to determine the optimal driving speed of the driving unit 100 based on the clothes information sensed in the sensing step A.

[0595] In addition, it is preferable to determine the rpm and driving time of the compressor, the driving time and rpm of the air supply fan based on the clothes information sensed in the sensing step A.

[0596] For this purpose, it is preferable to execute the sensing step A before the drying step S5.

[0597] In addition, when the mobile clothes hanger 100 is driven, if the clothes separate from the hanger part 700 and fall, the steam is concentrated and sprayed onto a specific area of the clothes, so there is a risk of damaging the clothes. Therefore, the mobile clothes hanger 100 can be driven from the standby step. In this case, it is preferable to drive the mobile clothes hanger 100 so that foreign matters, dust, and moisture attached to the clothes can be shaken off after the steam step S2.

[0598] Therefore, since the sensing step A is to drive the mobile clothes hanger 100 and sense the clothes information including the weight and length of the clothes, it can be performed after the steam step S2 and before the drying step S5.

[0599] On the other hand, the driving part 200 of the mobile clothes hanger 100 is preferably driven at a faster speed in the driving step S than in the sensing step. Therefore, the driving part 200 can be driven at a faster speed in the drying step S5 than in the sensing step A.

[0600] If the speed of the driving part 200 for processing the clothes in the driving step S is regarded as the processing speed, the processing speed can be set to be faster than one or more of the first speed and the second speed at which the driving part 200 is driven in the sensing step A. The processing speed can also be the same as the second speed.

[0601] In addition, the sensing step A can be performed during the standby step S3 and the cooling step S4. Therefore, the driving part 200 can be driven at the first speed starting from the standby step S3 or the cooling step S4.

[0602] In the sensing step A, the weight sensing step A1 can be performed first, and then the length sensing step A2 can be performed.

[0603] Therefore, in the weight sensing step A1, the speed of the driving part 200 or the vibration of the clothes can be less than the speed of the driving part 200 or the clothes vibration in the length sensing step A2.

[0604] In the weight sensing step A1, the driving part 200 can be driven in a region below the first speed.

[0605] The length sensing step A2 can be performed in a region above a second speed faster than the weight sensing step A1.

[0606] The weight sensing step A1 and the length sensing step A2 can be continuously performed.

[0607] In the sensing step A, the control unit C can drive the mobile clothes hanger at two or more speeds. The mobile clothes hanger 100 can be driven at a time point after driving the steam generating unit 50.

[0608] Through the sensing step A, the control unit C can drive the mobile clothes hanger 100 at a speed range before the clothes start to shake in the form of a resonance frequency or a standing wave and at a speed range above where the clothes start to shake in the form of a resonance frequency or a standing wave.

[0609] In addition, through the length sensing step A2 in the sensing step A, the control unit C can drive the driving unit 200 at at least two or more speed ranges faster than the second speed.

[0610] Through the weight sensing step A1, the control unit C can be set to drive the mobile clothes hanger at a speed range below the speed at which the clothes start to shake in the form of a standing wave to sense the weight of the clothes.

[0611] Through the length sensing step A2, the control unit C can be set to drive the mobile clothes hanger at a speed range above the speed at which the clothes start to shake in the form of a standing wave to sense the length of the clothes.

[0612] Through the length sensing step A2, the control unit C can drive the mobile clothes hanger to change the standing wave or resonance frequency of the clothes to sense the length of the clothes.

[0613] Since the driving speed of the driving unit 200 that makes the clothes shake at the resonance frequency can also be sensed in the sensing step A, after the sensing step A, the control unit C can drive the mobile clothes hanger 100 at the resonance speed or the second speed or a speed range corresponding to a multiple of the second speed.

[0614] As a result, the control unit C can drive the driving unit 200 at two or more speed ranges after driving the steam generating unit 50.

[0615] If the sensing step A ends, the control unit C drives the compressor 53, the air supply fan, and the driving speed of the driving unit 200 in accordance with the clothing information in the driving step after the sensing step A.

[0616] The speed at which the driving unit 200 is driven in the sensing step A can also be set to be lower than the speed at which the driving unit 200 is driven in the driving step B.

[0617] Through the sensing step A, if one or more of the weight and length of the clothes are different, the control unit C can set the processing speed differently.

[0618] For example, if the weight of the clothing is heavy, the control unit C may set the processing speed to a multiple range of the resonance speed. Thereby, a standing wave is formed in the clothing, and thus the vibration energy generated in the clothing can be minimized.

[0619] If the weight of the clothing is heavy, the control unit C may set the processing speed to be less than the processing speed when the weight of the clothing is light. Thereby, the vibration energy generated in the clothing can be minimized.

[0620] If the length of the clothing is long, compared with when the length of the clothing is short, the control unit C may set the processing speed to a multiple range of the resonance speed. Thereby, it can be operated to evenly disperse the dust removal force over the entire clothing.

[0621] If the length of the clothing is long, the control unit C may set the processing speed to be smaller compared with when the length of the clothing is short. Thereby, the vibration energy generated in the clothing can be minimized.

[0622] In addition, if the weight of the clothing is heavy, the control unit C may control the machine room so that the supply amount or the supply time of the hot air is greater than when the weight of the clothing is light. Thereby, even if the clothing is heavy, the renovation effects of sterilization, deodorization, drying, and wrinkle removal can be ensured.

[0623] In addition, if the length of the clothing is long, the control unit C may control the machine room so that the supply amount or the supply time of the hot air is greater than when the length of the clothing is short. Thereby, hot air is evenly supplied to the long clothing, and thus the renovation effects of sterilization, deodorization, drying, and wrinkle removal can be ensured.

[0624] If it is sensed in the sensing step A that the clothing is heavy, the duration of the driving step may be set to be longer than when it is sensed that the clothing is light. Therefore, the time for evenly supplying hot air and steam to the entire heavy clothing is extended, and thus the renovation effect can be ensured.

[0625] If it is sensed in the sensing step A that the clothing is heavy, in the driving step S, the driving time or the driving rpm of the compressor may be set to be greater than when it is sensed that the clothing is lighter. Thereby, hot air is more sufficiently supplied to the entire heavy clothing, and thus the renovation effect can be ensured.

[0626] If it is sensed in the sensing step A that the clothing is long, the driving step S may be driven at a larger speed range than when it is sensed that the clothing is shorter.

[0627] Since the driving of the compressor 83 in the driving step S is performed after the sensing step A, the control unit C can drive the driving unit 200 at a speed that causes the clothing to shake in the form of a resonance frequency or a standing wave when supplying one or more of steam and hot air to the inner casing.

[0628] In addition, since the processing speed is determined by the resonance frequency and the like sensed in the sensing step A, the control unit C can drive the moving clothes hanger 100 when supplying one or more of steam and hot air to the inner casing so that the clothing changes to an n - multiple of the resonance frequency or an n - multiple of the standing wave and shakes.

[0629] The driving of the compressor 83 in the driving step S is performed after the sensing step A, so it can be regarded as the sensing step A driving the moving clothes hanger 100, but the driving of at least one of the steam generator 51 and the compressor 83 is blocked.

[0630] Figure 24 Another embodiment of the control method of the clothing processing apparatus of the present invention is shown.

[0631] Hereinafter, the description will be centered on the parts different from Figure 23 the embodiment, and the same parts will be omitted to prevent repetitive description.

[0632] As the length and weight of the clothing are different, it is necessary to change the amount of steam supplied to the clothing and the duration of the steam.

[0633] Therefore, the sensing step A can be performed before the steam step S2.

[0634] The sensing step A can be performed during the heating step S1. In the heating step S1, although water is heated by driving a heater inside the steam generator 51, as a step where steam has not yet been generated inside the steam generator 51, this step is a step for preparing the driving step S.

[0635] Therefore, the sensing step A is performed to overlap at least a part of the heating step S1, so as to prevent the delay of the drying operation.

[0636] In addition, since the steam step S2 can be performed based on information such as the weight, length, and material of the clothing sensed in the sensing step A, the steam step S2 can supply an appropriate amount of steam to the placed clothing.

[0637] Accordingly, if the weight of the clothing is heavy, the control unit C can control the machine chamber 30 so that the steam injection amount is larger than when the weight of the clothing is light or the steam injection time is longer than when the weight of the clothing is light. That is, the driving time or driving output of the heater in the steam generator 51 can be set larger. Thereby, steam can be uniformly supplied to the entire heavy clothing, and thus the renovation effect can be maximized.

[0638] If the length of the clothing is long, the control unit C can control the machine chamber 30 so that the steam injection amount is larger than when the length of the clothing is short or the steam injection time is longer than when the length of the clothing is short. That is, the driving time or driving output of the heater in the steam generator 51 can be set larger. Thereby, steam can be uniformly supplied to the entire clothing, and thus the renovation effect can be maximized.

[0639] As a result, if it is sensed in the sensing step A that the clothing is heavy, the driving step S can set the driving time of the steam generator 51 longer than when it is sensed that the clothing is light.

[0640] In addition, if it is sensed in the sensing step A that the clothing is long, the driving step S can set the driving time of the steam generator 51 longer than when it is sensed that the clothing is short.

[0641] Of course, in this case, the driving of the moving hanger 100 can also be interrupted in the steam step S2. However, in order to uniformly inject steam onto the clothing in the steam step S2, the moving hanger 100 can also be driven.

[0642] Figure 25 An embodiment is shown in which the clothing treatment apparatus of the present invention also senses the material and water content performance.

[0643] The clothing treatment apparatus of the present invention can drive the moving hanger 100 at least at any one time before and after driving the steam generation unit 50 to calculate one or more of the material and water content performance of the clothing.

[0644] The clothing treatment apparatus of the present invention can sense one or more of the material and water content performance of the clothing in the sensing step A.

[0645] That is, the clothing treatment apparatus of the present invention may further include a material sensing step A3 for sensing the material and water content performance of the clothing in the sensing step A.

[0646] The material of the clothing may include the linear density (m) of the clothing. Therefore, the clothing treatment apparatus of the present invention can sense whether the clothing is soft or hard.

[0647] The water-containing property may include whether the clothing is hydrophilic or hydrophobic. Thus, the clothing treatment apparatus of the present invention can sense whether the clothing is hydrophilic or hydrophobic.

[0648] The control unit C, the mechanical chamber 30, and the moving clothes hanger 100 may function as a sensing unit for sensing clothing information.

[0649] The clothing treatment apparatus of the present invention may have a sensing unit capable of sensing the clothing information, and can be regarded as the sensing unit including the control unit C, the mechanical chamber 30, and the moving clothes hanger 100.

[0650] When driving at least any one of the moving clothes hanger 100 and the steam generating unit 50, the control unit C may be configured to sense a change in the state of the clothing to calculate the material and water-containing property of the clothing. For example, after sensing the state of the clothing before supplying steam to the clothing and the state of the clothing after supplying steam to the clothing, the change in the state of the clothing may be sensed to calculate one or more of the material and water-containing property of the clothing.

[0651] Refer to Figure 25 In (a) of, the clothing treatment apparatus of the present invention may drive the moving clothes hanger 100 before the material sensing step A3 to perform one or more of the weight sensing step A1 and the length sensing step A2.

[0652] Refer to Figure 25 In (b) of, the clothing treatment apparatus of the present invention drives the steam supply unit 50 in the sensing step A to supply a preset amount of steam to the clothing for a preset time.

[0653] The purpose of driving the steam supply unit 50 in the sensing step A is not to supply steam to the clothing, but to induce a change in the state of the clothing. Therefore, the time for driving the steam supply unit 50 in the sensing step A may be set shorter than the time for driving the steam supply unit 50 in the driving step S.

[0654] Refer to Figure 25 In (c) of, after interrupting the driving of the steam supply unit 50, the clothing treatment apparatus of the present invention may further perform one or more of the weight sensing step A1 and the length sensing step A2. Through this, the control unit C may calculate one or more of the material and water-containing property of the clothing.

[0655] For example, the control unit C can sense a change in the weight of the clothing based on the supply of the steam, thereby sensing one or more of the material and water-containing properties of the clothing. If the change in the weight of the clothing is greater, it can be determined that the clothing is hydrophilic, and if the change in the weight of the clothing is smaller, it can be determined that the clothing is hydrophobic.

[0656] In addition, the control unit C can sense the material of the clothing by using the characteristic that the degree of steam absorption by the clothing varies according to the material of the clothing. For example, the supply of steam to the clothing by the steam supply unit 50 in the sensing step A can be set to a fixed amount, and the change in the weight of the clothing according to the material of the clothing is digitized and pre-stored in the control unit C. Therefore, the control unit C can sense the material of the clothing through the data. Thus, the control unit C can determine whether the clothing is hydrophobic or hydrophilic, whether the clothing is hard or soft, etc.

[0657] The control unit C can sense the material of the clothing by considering the change in the length sensing step A2 before and after the driving of the steam generation unit 50.

[0658]

[0659] In the length sensing step A2, the control unit C can sense the resonance frequency of the clothing through formula (1).

[0660] At this time, V includes the weight (mg) of the clothing and the linear density (m) value of the clothing, and either the weight (mg) of the clothing or the linear density (m) of the clothing can change through the supply of the steam. However, the length of the clothing can be fixed before and after the steam supply.

[0661] Therefore, the control unit C can sense one or more of the material and water-containing properties of the clothing through one or more of the change in the resonance frequency of the clothing, the change in the weight of the clothing, and the change in the linear density of the clothing before and after the steam supply.

[0662] On the other hand, the material of the clothing can generally be estimated by the linear density (m). Therefore, the linear density (m) of the clothing can be calculated by considering the change in the resonance frequency of the clothing and the change in the weight of the clothing before and after the steam supply. Thus, the control unit C can analyze the linear density of the clothing to analyze whether the clothing is hard or soft, and whether the clothing is hydrophilic or hydrophobic.

[0663] As a result, the clothing treatment apparatus of the present invention can sense the weight and length of the clothing in the sensing step A, and after supplying steam, sense the weight and length of the clothing again. During this process, considering that the length of the clothing does not change, the material of the clothing can be sensed.

[0664] Figure 26 An embodiment of sensing clothing information including the material of the clothing through the sensing step is shown.

[0665] In the clothing treatment apparatus of the present invention, if the sensing step A is executed, a weight sensing step A1 of sensing the weight of the clothing by driving the driving unit 200 at the first speed V1 and a length sensing step A2 of sensing the length of the clothing by driving the driving unit 200 stepwise at a speed above the second speed V2 can be executed.

[0666] The length sensing step A2 may include driving the driving unit 200 at two or more speed intervals of the minimum resonance speed V21, the second resonance speed V22 which is twice the minimum resonance speed, and the Kth resonance speed V2K which is K times the minimum resonance speed.

[0667] The control unit C can supply steam to the clothing after storing the sensed weight and length of the clothing. The supply amount of the steam can be fixed as a reference amount.

[0668] The duration of the length sensing step A2 can be set longer than the duration of the weight sensing step A1. Thus, the time for the driving speed of the driving unit 200 to change in different intervals can be ensured sufficiently.

[0669] The time for steam supply can be set longer than the length sensing step A2. Thus, sufficient time for generating steam in the steam supply unit 50 and exposing the clothing to the steam can be ensured.

[0670] On the other hand, if the steam is supplied, the control unit C can execute a material sensing step A3.

[0671] The material sensing step A3 may include re - executing the weight sensing step A1 and the length sensing step A2 after steam supply. The control unit C may determine whether the clothing is hydrophilic or hydrophobic based on the weight change of the clothing in the weight sensing step A1. The control unit C may determine whether the clothing is hard or soft based on the linear density (m) of the clothing in the length sensing step A2. The material sensing step A3 may be described based on re - executing the weight sensing step A1 and the length sensing step A2 after steam supply. However, since the step of supplying steam is necessary for the material sensing, the material sensing step A3 may also include a steam supply step.

[0672] The sensing step A may interrupt the driving of the moving clothes hanger 100 when the steam generating unit 50 is operating.

[0673] On the other hand, the control unit C may also calculate the type of clothing based on the clothing information obtained in the weight sensing step A1, the length sensing step A2, and the material sensing step A3.

[0674] For example, the types of clothing corresponding to the clothing information in the control unit C are digitized and stored. Thus, the control unit C can determine the material and type of clothing, such as whether the clothing is "a dress made of cotton material" or "a scarf made of cashmere material", based on the weight, length, and material of the clothing.

[0675] On the other hand, the clothing processing device of the present invention may execute a re - supply step of re - supplying steam to the clothing after the material sensing step A3. In the re - supply step, the steam supply unit 50 is driven. At this time, the amount of steam may be changed and supplied differently from when steam was supplied previously.

[0676] The control unit C may determine whether the clothing is hydrophilic or hydrophobic, etc. in the material sensing step A3. The control unit C may change the steam supply amount in the re - supply step according to the material of the clothing.

[0677] For example, if it is sensed in the material sensing step A3 that the clothing is hydrophilic, the steam supply amount may be increased in the re - supply step. Additionally, if it is sensed in the material sensing step A3 that the clothing is hydrophobic, the steam supply amount may also be increased in the re - supply step.

[0678] After that, the control unit C may re - execute the material sensing step A3 of the clothing. Thus, it can be verified whether the material of the clothing is the same as the result of the previous execution of the material sensing step A3.

[0679] For example, in the first material sensing step A3, it is sensed that the clothing is hydrophilic. However, in the case where the supply amount of steam is increased in the re - supply step, if the weight of the clothing is significantly increased in the second material sensing step A3, it can be confirmed that the clothing being hydrophilic is correct.

[0680] However, if in the first material sensing step A3 it is sensed that the clothing is hydrophobic, and in the case where the supply amount of steam is increased in the re - supply step, if the weight of the clothing is increased in the second material sensing step A3, it can also be determined that the clothing is not hydrophobic.

[0681] As a result, in the clothing processing apparatus of the present invention, the material sensing step A3 can be performed multiple times, and it can be confirmed whether the sensed material of the clothing is correct by spraying steam on the clothing in different ways between each of the material sensing steps A3.

[0682] In other words, the control unit C can drive the moving clothes hanger 100 after driving the steam generating unit 50, and drive the moving clothes hanger 100 again after driving the steam generating unit 50 again to calculate the clothing information.

[0683] Thus, the control unit C can drive the moving clothes hanger to calculate the clothing information after driving the steam generating unit 50, and drive the moving clothes hanger to verify the calculated clothing information after driving the steam generating unit 50 again.

[0684] The amount of steam supplied to the accommodation space 21 when the steam generating unit 50 is driven for the first time and the amount of steam supplied to the accommodation space 21 when the steam generating unit 50 is driven for the second time can be set to be different from each other.

[0685] On the other hand, when driving the moving clothes hanger 100 in the sensing step A, the steam supply can be interrupted. Conversely, when driving the steam generating unit 50, the driving of the moving clothes hanger 100 can be interrupted. Thus, it is possible to prevent the clothing from separating from the moving clothes hanger 100 and blocking the steam supplied from the steam generating unit 50, and it is possible to prevent the degree of the clothing containing steam from changing.

[0686] Figure 27 Another embodiment of sensing the material of the clothing is shown.

[0687] As described above, the sensing step A may include a weight sensing step A1 and a length sensing step A2.

[0688] However, the material sensing step A3 can be set as a step of driving the steam generating unit 50 and the moving clothes hanger 100 simultaneously.

[0689] That is, the material sensing step A3 may include driving the steam generating unit 50 while driving the mobile clothes hanger 100 to sense changes in the weight of the clothes, the length of the clothes, and the resonance frequency of the clothes, thereby calculating the material of the clothes.

[0690] Thus, the sensing step A can be regarded as being able to drive the steam generating unit 50 and the mobile clothes hanger 100 simultaneously.

[0691] When driving the steam generating unit 50, the driving speed of the driving unit 200 can be changed. Thus, the control unit C can obtain various data according to the driving speed of the driving unit 200, so as to accurately calculate the material of the clothes.

[0692] The material sensing step A3 can be executed multiple times. In the material sensing step A3, the amount of steam supplied each time steam is supplied can vary. Thus, in each material sensing step A3, the control unit C can obtain more information through the mobile clothes hanger 100 to calculate the clothes information.

[0693] Figure 28 An additional embodiment of the control method of the clothes processing device of the present invention is shown.

[0694] As described above, the clothes processing device of the present invention can execute the sensing step A and the driving step S.

[0695] The driving step S may include: a heating step S1 of driving the steam generating unit 50 to heat the water contained in the steam generator 51; a steam step S2 of supplying steam to the accommodation space 21 when the water in the steam generator 51 boils to generate steam; a standby step S3 of interrupting the driving of the steam generator 51 after injecting a set amount or a set time of the steam; a cooling step S4 of only driving the air supply fan to cool the clothes while cooling the air in the accommodation space 21 to improve the efficiency (COP) of the heat pump system; and a drying step S5 of driving the compressor 83 and the air supply fan to supply hot air to the accommodation space 21.

[0696] The control unit C can be set to drive at least one of the steam generator and the mobile clothes hanger in the sensing step A to calculate one or more pieces of clothes information including the material of the clothes, properties including hydrophilicity or hydrophobicity, and the type of the clothes.

[0697] In the steam step S2, the amount of steam injected into the clothes can also preferably be set differently according to the weight, length, material, properties, and type of the clothes. This is because the optimal steam supply amount has been determined according to the clothes information.

[0698] To this end, the clothing treatment device of the present invention may perform the sensing step A before the steam step S2 or at the initial stage of the steam step S2. Additionally, the sensing step A may be performed starting from the heating step S1.

[0699] In the heating step s1, water is heated in the steam generator 50 to generate steam, so it may be a step of not supplying steam to the accommodation space 21.

[0700] Therefore, the control unit C may perform the weight sensing step A1 and the length sensing step s2 in the heating step S1.

[0701] If the steam step S2 starts, the control unit C may perform the material sensing step A3. Specifically, the material sensing step A3 may be to perform the weight sensing step A1 and the length sensing step s2 after supplying steam to the clothing.

[0702] In the material sensing step A3, the control unit C may drive the moving clothes hanger 100 before driving the steam generating unit 50 or after driving the steam generator to calculate the clothing information.

[0703] Specifically, the control unit C may be set to calculate the clothing information after setting the current value when driving the driving unit 200 before sensing and driving the steam generating unit 50 and the current value when driving the driving unit 200 after driving the steam generating unit 50.

[0704] In the sensing step A, through the weight sensing step A1 and the length sensing step A2, the driving unit 200 may be driven in two or more speed ranges before driving the steam generating unit 50. The control unit C may drive the driving unit 200 in a speed range before the clothing starts to shake in the form of a resonance frequency or a standing wave and in a speed range above the speed at which the clothing starts to shake in the form of a resonance frequency or a standing wave.

[0705] In the sensing step A, through the material sensing step A3, the control unit C may drive the moving clothes hanger 100 at two or more frequencies after driving the steam generating unit 50.

[0706] In the material sensing step A3, the control unit C may drive the driving unit 200 in a speed range before the clothing starts to shake in the form of a resonance frequency or a standing wave and in a speed range above the speed at which the clothing starts to shake in the form of a resonance frequency or a standing wave.

[0707] As a result, by performing the sensing step A, the control unit C can drive the mobile clothes hanger before and after driving the steam generator unit 50, respectively.

[0708] The control unit C can sense the weight change of the clothes to calculate the clothes information, or can calculate the clothes information through the difference in current values output from the driving unit 200.

[0709] In addition, the control unit C can sense the change in the speed of the driving unit 50 that causes the clothes to generate a resonance frequency or a standing wave before and after driving the steam generating unit 50 to sense the clothes information. At this time, the formulas (1) and (2) can be applied.

[0710] If the material sensing step A3 ends, the control unit C can set the amount of steam supplied to the clothes in the steam step S2 based on the clothes information sensed in the sensing step A.

[0711] For example, when it is sensed that the clothes are hydrophilic or closer to hydrophilic, compared with when the clothes are hydrophobic, the control unit C can control to generate more steam in the steam generating unit 50 when performing the steam step S2. Thereby, the clothes can contain more moisture, and thus the renovation effect of the clothes can be maximized.

[0712] On the contrary, when the clothes are hydrophobic, less steam can be generated, so that the clothes can be protected while saving water and energy.

[0713] Furthermore, the control unit C can set one or more of the driving speed of the driving unit 200 and the driving speeds of the compressor 83 and the air supply fan after the standby step S3 based on the clothes information sensed in the sensing step A. For example, when it is sensed that the clothes are hydrophilic, compared with when they are hydrophobic, the control unit C can set the driving time or driving rpm of the compressor to be greater in the drying step S5. Thereby, it is possible to ensure sufficient time to dry the moisture contained in the clothes.

[0714] On the contrary, when the clothes are hydrophobic, it is possible to prevent the clothes from being over-dried by hot air and save energy.

[0715] From another perspective, if it is sensed in the sensing step A that the clothes are hydrophilic, the duration of the driving step S can be set to be longer than when it is sensed that the clothes are hydrophobic. Since hydrophilic clothes contain more moisture, this is to fully shake off dust after drying them sufficiently.

[0716] If it is sensed in the sensing step A that the clothing is hydrophilic, the driving time of the steam generator 50 in the driving step S can be set longer than when it is sensed that the clothing is hydrophobic.

[0717] This is to supply more moisture to the hydrophilic clothing, thereby maximizing the renovation effect.

[0718] In addition, if it is sensed in the sensing section A that the material of the clothing is hard, in the driving step S, the moving clothes hanger 100 can be controlled to shake faster than when the clothing is sensed to be soft. This is because relatively less twisting occurs in hard clothing, and in order to provide sufficient dust removal force to the clothing.

[0719] In addition, since the sensing step A is performed before the drying step S5 and starts to be performed before the steam step S2, it can be regarded as driving one or more of the moving clothes hanger 100 and the steam generator 50 in the sensing step A, but blocking the driving of the compressor 83.

[0720] In the driving step S, if the steam step S2 ends, the moving clothes hanger 100 is driven at a processing speed, so it can be regarded as driving the moving clothes hanger 100 after the steam generator 50 operates.

[0721] Figure 29 The structure for the clothing processing apparatus of the present invention to sense clothing information is shown.

[0722] Refer to Figure 29 In the door 11 of the clothing processing apparatus of the present invention, the display unit D can be provided.

[0723] Of course, the display unit D can also be provided on the cabinet 10. However, since the door 11 forms the front of the cabinet 10, if the display unit D is provided on the door 11, the user can easily check the state of the display unit D.

[0724] The display unit D can be set to display the information received from the control unit C to the outside in one or more of visual information and sound information, and can be set to also display the clothing information sensed by the control unit C to the outside.

[0725] The display unit D can display the program information being executed by the control unit C and can be set as a screen such as a liquid crystal screen.

[0726] In addition, at least a part of the display unit D is set as a touch panel and can perform the function of the input unit I.

[0727] Refer to Figure 29In (b) thereof, the display unit D may be configured to display one or more of the weight D1 of the clothing, the length D2 of the clothing, and the material D3 of the clothing in one or more of the ways of numbers, characters, and pictograms.

[0728] Refer to Figure 29 In (c) thereof, the display unit D may display more detailed information related to the material or properties of the clothing. For example, the display unit D may be configured to display one or more of the physical property information D4 related to whether the clothing is hydrophilic / hydrophobic, the type D5 of the clothing, and the linear density information D6 of the material in one or more of the ways of numbers, characters, and pictograms.

[0729] The display unit D may display all of the clothing information D1 to D6 as described above, may selectively display them, or may display them alternately.

[0730] The display unit D may be controlled to immediately display it whenever the control unit C senses specific clothing information, and may be controlled to display the clothing information when the control unit C senses all the detectable clothing information.

[0731] For example, the control unit C may drive the mobile hanger 100 to sense the weight and length of the clothing before driving the mechanical chamber 30.

[0732] Therefore, the display unit D may be configured to display one or more of the weight and length of the clothing before driving the mechanical chamber 30.

[0733] If a power supply instruction is input through the input unit I to supply power, or the door 11 closes the accommodation space 21, the control unit C may drive the mobile hanger 100 to directly sense the weight and length of the clothing.

[0734] Therefore, the display unit D may be configured to display one or more of the weight and length of the clothing if power is input or the door 12 closes the opening.

[0735] The control unit C may drive the mobile hanger 100 to sense the weight and length of the clothing before driving the steam generator 51 or the compressor 83.
