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 are clothing treatment apparatuses that perform 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, in the existing clothing treatment apparatus, when supplying hot air and steam to the clothing, the moving hanger can be used to shake the clothing, and thus has an effect of being able to shake off dust and foreign matters 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, depending on the driving frequency and driving speed of the moving hanger, the degree and form of shaking of the clothing may be different.

[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 apparatuses have 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 Laid-Open Patent Publication No. 2021-016611A)

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

[0011] However, referring to Figure 1 the left drawing in (a) of, 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 large, resulting in the stretching of the clothing, and there is a risk of damaging the clothing.

[0013] Thus, referring to Figure 1 the right drawing in (a) of, 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 treatment device may be in the heaviest state when water or steam is initially supplied. The inertial force of the heavy clothing is large, so it may not be easily shaken by the mobile hanger.

[0015] In addition, as the moisture in the clothing is evaporated by supplying hot air, 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 in (b) of, in the initial stage when the existing clothing treatment device presumes that the clothing is 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 by using the hot air or separates the moisture by 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 evenly transmit the dust removal force to the whole 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, 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, existing clothing treatment devices have limitations in that, although the moving form of the mobile clothes hanger varies according to the weight, length, material, etc. of the clothes, they cannot drive the mobile clothes hanger in accordance with the state of the clothes.

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

[0022] A clothing treatment device having a mobile clothes hanger generally supplies steam and hot air to the placed clothes to renovate the clothes.

[0023] Specifically, an existing clothing treatment device is driven in the following steps: a preheating step C1 of preheating a 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, an 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 may 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, existing clothing treatment devices have limitations in that they not only block driving the mobile clothes hanger before hot air supply to obtain clothing information, but also fundamentally block driving the mobile clothes hanger before steam supply to obtain clothing information.

[0027] In addition, since 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 or the like is formed. 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 perform renovation in an optimal manner. Summary of the Invention

[0034] The problem to be solved by the present invention is to provide a clothing treatment device capable of calculating one or more of the weight and length of the clothing placed by shaking the moving hanger of the clothing.

[0035] The problem to be solved by the present invention is to provide a clothing treatment device that drives the moving hanger in an optimal manner based on one or more of the sensed weight and length of the clothing.

[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] To solve the above problems, the present invention provides a clothing treatment device capable of sensing the length information of the clothing while driving the moving hanger.

[0041] The present invention can drive the moving hanger to sense the length of the clothing.

[0042] If the length of the clothing is determined, the characteristic speed at which a standing wave is generated is determined according to the speed. At this time, the transmission speed v of the vibration is determined by the tension (T) of the wire, the linear density (μ) of the wire, and the weight (m) of the load as described by the formula. If the length (l) of the clothing is determined, the frequency (fn) of the nth-order standing wave is determined by the following formula.

[0043]

[0044] Therefore, when the driving frequency of the moving hanger is a resonance frequency such as f1, f2, f3..., the clothing forms a standing wave pattern. Therefore, in this interval, due to the resonance of the clothing, the second harmonic component of the load torque applied to the moving hanger will increase significantly.

[0045] In the case of the load of the clothing care machine, the greater the driving speed, the gradually increasing load torque caused by friction and inertia. However, there is a singularity where the amplitude or waveform of the second harmonic caused by such resonance will increase significantly compared to the amplitude or waveform of the second harmonic caused by the increase in the driving speed that can be predicted normally.

[0046] On the other hand, loads with longer lengths and loads with shorter lengths will form different second harmonics and vibrate. Utilizing such characteristics, information on the length can be obtained by measuring changes in the form or amplitude of the second harmonic as the driving speed increases.

[0047] In addition, the clothing treatment device of the present invention can drive the moving hanger and supply steam to the clothing, and then drive the moving hanger again. Thus, information on the material of the clothing can be obtained from the level of change in weight before and after steam supply.

[0048] In other words, the material, hydrophilicity, or hydrophobicity of the clothing can be judged from the level of change in the measured value of the load before and after steam injection.

[0049] For example, if the measured value of the weight increases significantly after steam injection, it can be judged that the clothing is made of a hydrophilic material with excellent water absorption, and based on the level of change in the measured value of the weight, the hydrophilic hydrophobic materials are quantified and classified.

[0050] The steam supply amount in the first program for sensing the material of the clothing can be controlled quantitatively. At this time, the quantitative control can also be achieved by supplying steam at a set temperature within a preset time, without the need for additional means of precisely measuring the weight of the steam.

[0051] In order to improve the sensing discrimination of the weight change amount, an enhanced amount of steam can be supplied in the case of sensing a large load condition.

[0052] However, under the condition of the same weight, a fixed amount of steam needs to be supplied to clearly determine the material information.

[0053] In the second program for sensing the material of the clothing, the measured clothing material information can be used to variably control the steam supply amount.

[0054] The control variable can be controlled in a direction of increasing the steam injection amount when the clothing is a hydrophilic material and decreasing the steam injection amount when the clothing is a hydrophobic material.

[0055] To solve the above problems, the present invention provides a clothing treatment device, and a control unit of the clothing treatment device is configured to drive at least one of the moving clothes hanger and the steam generator to calculate one or more of the weight, length, material, and water content performance of the clothing.

[0056] The control unit can be configured to drive the moving clothes hanger to sense the weight of the clothing, drive the moving clothes hanger before and after driving the steam generator respectively, and sense one or more of the material and water content performance of the clothing through the weight change of the clothing.

[0057] The control unit can drive the moving clothes hanger to sense the weight or the resonance frequency of the clothing, drive the moving clothes hanger after driving the steam generator to sense the change in the weight or the resonance frequency of the clothing, and sense one or more of the material and water content performance of the clothing.

[0058] After calculating one or more of the material and water content performance of the clothing, the control unit can drive the steam generator again, and then drive the moving clothes hanger to verify one or more of the calculated material and water content performance of the clothing.

[0059] The steam amount supplied when the steam generator is driven for the first time and the steam amount supplied when the steam generator is driven later can be set to be different from each other.

[0060] The control unit can be configured to drive the moving clothes hanger to sense the weight and length of the clothing, and the driving frequency of the moving clothes hanger for sensing the weight of the clothing can be set to be lower than the driving frequency of the moving clothes hanger for sensing the length of the clothing.

[0061] The control unit can drive the moving clothes hanger to sense the weight of the clothing at a frequency lower than the fundamental frequency at which the clothing starts to generate waveforms or vibrations, and can drive the moving clothes hanger to sense the length of the clothing at a frequency higher than the fundamental frequency.

[0062] The control unit can sense the weight of the clothing before sensing the length of the clothing.

[0063] The control unit can sense the length of the clothing while changing the frequency of driving the moving clothes hanger.

[0064] The control unit can periodically change the frequency of driving the moving clothes hanger at preset times and sense the length of the clothing.

[0065] The control unit can sense the driving frequency of the moving clothes hanger when the clothing vibrates in the form of a standing wave to calculate the length of the clothing.

[0066] The control unit can sense the frequency of the moving clothes hanger when the clothing vibrates in the form of two or more standing waves to calculate or confirm the length of the clothing.

[0067] The control unit can drive the moving clothes hanger at least at any time before and after driving the steam generator to calculate one or more of the material and water content performance of the clothing.

[0068] The control unit can drive the moving clothes hanger before driving the steam generator and drive the moving clothes hanger after driving the steam generator to calculate the material or water content performance of the clothing.

[0069] The control unit can be set to drive the moving clothes hanger at two or more frequencies before and after driving the steam generator to calculate the material or water content performance of the clothing.

[0070] The control unit can drive the moving clothes hanger at a frequency lower than the resonance frequency at which the clothing starts to vibrate in the form of a standing wave and at a frequency above the resonance frequency before and after driving the steam generator to calculate the material or water content performance of the clothing.

[0071] The control unit can sense the frequency change of the moving clothes hanger that causes the clothing to form a standing wave before and after driving the steam generator to calculate the material or water content performance of the clothing.

[0072] The control unit can be set to drive the moving clothes hanger after driving the steam generator and drive the moving clothes hanger again after driving the steam generator again to calculate the material or water content performance of the clothing.

[0073] The mobile clothes hanger may include: a power transmission unit disposed in the inner housing and supporting the load of the clothes; and a driving unit providing power for reciprocating movement of the power transmission unit. The control unit may calculate the material or water-containing performance of the clothes through the difference in the current values output from the driving unit before and after driving the steam generator.

[0074] If it is sensed that the clothes are hydrophilic, the control unit may control the steam generator to supply more steam to the accommodation space than when the clothes are hydrophobic.

[0075] If it is sensed that the clothes are hydrophilic, the control unit may set the driving time of the compressor to be longer or set the driving rpm to be greater so as to supply more hot air to the accommodation space than when the clothes are hydrophobic.

[0076] To solve the above problems, the clothes processing apparatus of the present invention may include: a sensing unit sensing at least one of the material, hardness, hydrophilicity or hydrophobicity, and type of the clothes placed; and a display unit disposed on at least one of the cabinet and the door, displaying the clothes information sensed by the sensing unit.

[0077] The display unit may display the clothes information before driving the compressor.

[0078] If the input power or the door closes the opening, the display unit may display the clothes information.

[0079] It further includes an input unit disposed on the cabinet, receiving an instruction to operate the machine room. If the input unit inputs, the display unit may display the clothes information.

[0080] To solve the above problems, the present invention provides a control method for a clothes processing apparatus, which includes: a sensing step of sensing at least one of the weight, length, material, hardness, type, and water-containing performance of the clothes; and a driving step of supplying steam and hot air to the clothes to process the clothes.

[0081] The sensing step may drive both the mobile clothes hanger and the steam generator.

[0082] In the sensing step, when the steam generator is operating, the driving of the mobile clothes hanger may be interrupted.

[0083] In the sensing step, the steam generator and the mobile clothes hanger may be driven simultaneously.

[0084] In the driving step, the mobile clothes hanger may be driven after the steam generator is operating.

[0124] Refer to Figure 3 of (a), the clothing treatment device of the present invention may include a cabinet 100 forming the appearance and a door 11 rotatably coupled to the cabinet 10.

[0125] The door 11 may be set to have the same height and width as the front of the cabinet 100, and the door 11 may form the front of the clothing treatment device 1.

[0126] The door 11 may have an input unit for receiving an instruction capable of operating the clothing treatment device, and may have a display unit capable of visually, audibly, etc. displaying the operating state of the clothing treatment device to the outside.

[0127] Refer to Figure 3 of (b), an inner cabinet 20 may be provided inside the cabinet 10, and the inner cabinet 20 has an accommodation space 21 for accommodating clothing. The inner cabinet 20 may have an opening 21 for introducing and removing clothing in the front, and the opening 21 may be shielded by the door 11.

[0128] The inner housing 20 may be made of a series of plastic resins, and may be made of a series of reinforced plastic resins that will not deform even in an environment of air or heated air (hereinafter, hot air) and steam or moisture at a temperature higher than that of normal temperature air.

[0129] The inner housing 20 may be set such that its height is greater than its width. Thus, the clothing can be accommodated in the accommodation space 21 without being folded or wrinkled.

[0130] The clothing treatment apparatus 1 of the present invention may include a hanger unit capable of placing clothing on the accommodation space 21 of the inner housing 20. The hanger unit may be set to be installed on the inner housing 20 and placed on the movable hanger 100 for placing clothing.

[0131] The movable hanger 100 may be set to be exposed on the upper inner surface of the inner housing 20 so that the hanger unit 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 clothing. Later, the detailed structure of the movable hanger 100 will be described.

[0132] If the clothing is placed on the movable hanger 100, the clothing can be placed in the accommodation space 21 in a state of floating in mid-air and stretching in the height direction. Thus, the clothing placed in the accommodation space 21 can be evenly exposed to hot air and steam, and can be de-wrinkled using its own weight.

[0134] The pressing unit 40 may be set to be rotatably coupled to the inside of the door 11 to press the clothing fixed to the inner surface of the door 11 against the inner surface of the door 11.

[0135] The pressing unit 40 may generate desired creases on both side surfaces of the clothing.

[0136] The clothing treatment 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 accommodation space 21, or capable of purifying or dehumidifying the outside air of the cabinet 10 are provided in the mechanical chamber 30.

[0138] 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.

[0139] 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.

[0140] 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 for cooling or heating the air.

[0141] 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.

[0142] 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.

[0143] 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 sewer outlet, the user can detach and carry the water tank 31 and the drain tank 32 when needed.

[0144] The water tank 31 and the drain tank 32 may be arranged side by side in the width direction of the mechanical chamber 30.

[0145] In addition, the mechanical chamber 30 may further include a drawer 33 for accommodating articles required for managing the laundry, etc. The drawer 33 may be provided so as to be able to be pulled out from the mechanical chamber 30, and a space for accommodating articles such as an iron may be provided inside.

[0146] 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 so as to protrude from positions at the same height on both side surfaces of the inner housing 20.

[0147] The mounting table 60 may be provided with a light emitting part for irradiating light into the inner housing 20. The light emitting part may be provided so as to irradiate light to the inner side surface of the inner housing 20 to prevent glare.

[0148] Figure 4 An embodiment of the structure of the mechanical chamber is shown.

[0149] The mechanical chamber 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 providing a flow path for circulating the air inside the inner housing 20.

[0150] The duct 90 may form a circulation flow path communicating with the inflow port and the discharge port of the inner housing 20 respectively, 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.

[0151] 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, communicating with the inner housing 20 to allow air to flow in; a discharge duct 92, separated from the inflow duct 91 and communicating with the inner housing 20 to discharge air; and a moving duct 93, connecting the inflow duct 91 and the discharge duct 92 to form a flow path for air to move.

[0152] 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, and the expansion valve expands the refrigerant passing through the condenser 82, cools it and transmits it to the evaporator 81.

[0153] 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.

[0154] The evaporator 81 and the condenser 83 may be arranged along the air moving direction. 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.

[0155] The steam supply unit 50 may be arranged inside the duct 90.

[0156] The steam supply unit 50 may be arranged outside the duct 90 without obstructing the flow of the air moving along the duct 90.

[0157] 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.

[0158] 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.

[0159] The steam supply unit 50 may further include a recovery pipe 54 connecting the steam nozzle 52 and the steam generator 51.

[0160] 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 the steam is automatically supplied to the inner housing 20 under the action of the density difference, and the water is recovered to the steam generator 51 under the action of gravity.

[0161] The steam nozzle 52 may be made of a plastic material or the like, rather than 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.

[0162] The steam supply unit 50 may further include a steam pipe 53 connecting the steam generator 51 and the steam nozzle 52. The steam generated in the steam generator 51 may be supplied along the steam pipe 53 to the inside of the steam nozzle 52 and then supplied to the inside of the inner housing 20.

[0163] The mechanical room 30 may further include a water supply unit 60 that can supply water for generating steam in the steam supply unit 50.

[0164] The water supply unit 60 may be arranged to receive water from a water tank 31 placed in front of the mechanical room 30 and then supply it to the steam supply unit 50.

[0165] 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 to supply the water in the water supply pipe 61 to the supply pipe 63.

[0166] The water tank 31 may be detachably arranged in front of the pipe 90, and the water supply pump 62 may be disposed outside the pipe 90.

[0167] The supply pipe 63 may be arranged to communicate with the steam generator 51 to supply water to the steam generator 51.

[0168] Alternatively, the supply pipe 63 may be arranged to communicate with the steam nozzle 52 to supply water to the steam nozzle 52. That is, the water supply unit 60 may 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. Thereby, the flow path structure can be simplified.

[0169] The machine room 30 may further include a drainage unit 70 that collects the water condensed in the evaporator 81 into the drainage tank 32.

[0170] The drainage unit 70 may 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 pipe 90 to discharge the water collected at the lower part of the pipe 90 to the outside of the pipe 90. The drainage pump 72 supplies the water discharged by the discharge pipe 71 to the drainage tank 32. The drainage pipe 73 supplies the water supplied to the drainage pump 72 to the drainage tank 32.

[0171] On the other hand, the drainage unit 70 may further include a recovery pipe 74 that communicates the pipe 90 with the drainage tank 32 to redirect the water in the drainage tank 32 back into the pipe 90. Thereby, even when the drainage tank 32 is at full water level, it is possible to prevent the water collected in the drainage tank 32 from leaking to the outside.

[0172] When the clothes treatment device of the present invention performs renovation operations on clothes such as sterilization, deodorization, wrinkle removal, and drying, hot air and steam can be supplied to the inner housing 20 through the machine room 30 at an appropriate time, and the moisture discharged from the inner housing 20 can be condensed and collected into the drainage tank 32.

[0173] Figure 5 An embodiment of the mobile clothes hanger 100 of the clothes treatment device of the present invention is shown.

[0174] Refer to Figure 5 As shown in (a), the mobile clothes hanger 100 may include a hanging frame portion 700, a power transmission portion 400, a connecting portion 600, and a driving portion 200. The clothes or the clothes hanger portion 900 is placed on the hanging frame portion 700. A plurality of the power transmission portions 400 are combined with the hanging frame portion 700 to support the load of the clothes. The connecting portion 600 connects the plurality of power transmission portions 400. The driving portion 200 provides power for the connecting portion 600 and the plurality of power transmission portions 400 to move back and forth.

[0175] A plurality of power transmission portions 400 may be arranged at intervals along the direction in which the clothes are arranged in the accommodation space 21.

[0176] A plurality of power transmission units 400 may be arranged along the height direction of the laundry treating apparatus, and the connection unit 600 may be provided to be disposed on the upper surface of the inner case 20.

[0177] The connection unit 600 may be integrally provided with the plurality of power transmission units 400, and may be provided such that its upper part is connected to the driving unit 200.

[0178] The driving unit 200 and the connection unit 600 may be supported by an additional support frame and disposed on the upper part of the inner case 20.

[0179] The connection unit 600 may include a connection rod 630 provided in a rod shape, and the connection rod 630 may be connected to the driving unit 600 in a non-rotating yoke structure.

[0180] Accordingly, if the driving unit 600 generates rotational power, the connection rod 630 may reciprocate in the length direction or in the direction in which the power transmission units 400 are spaced apart.

[0181] The driving unit 200 may include a motor unit 210, a power shaft 240, a transmission unit 230, and a displacement generation unit 300. The motor unit 210 transmits the power that causes the connection rod 630 to reciprocate. The power shaft 240 rotates under the action of the motor unit 210. The transmission unit 230 transmits the power of the power shaft 240. The displacement generation unit 300 is connected to the transmission unit 230 to deform the rotational motion of the power shaft 240 into a motion along a preset trajectory.

[0182] For example, the transmission unit 230 may include a transmission rod 236. One end of the transmission rod 236 is coupled to the power shaft 240, and the other end extends in the radial direction of the rotation shaft 210 such that the transmission rod 236 rotates together with the power shaft 240. The displacement generation unit 300 may include an eccentric shaft 310. The eccentric shaft 310 is coupled to the other end of the transmission rod 236 and is coupled to the connection rod 630. The eccentric shaft 310 may be provided to rotate along a trajectory longer than that of the power shaft 240.

[0183] Refer to Figure 5 As shown in (b), the connection 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 connection rod 630. For example, the slit 631 may be formed along the thickness direction of the connection rod 630.

[0184] The length of the slit 631 can be set to be more than twice the rotation radius R of the eccentric shaft 310, and the width of the slit 631 can be formed to be greater than the diameter of the eccentric shaft 310.

[0185] Figure 6 An operation example of the moving clothes hanger is shown.

[0186] Referring to Figure 6 (a) of, the power shaft 240 is in a fixed 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.

[0187] The eccentric shaft 310 can 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 can receive the force moving to the right side by using the eccentric shaft 310, and the connecting rod 630 can move to the right side.

[0188] Referring to Figure 6 (b) of, the eccentric shaft 310 can 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 can receive the force moving to the left side by using the eccentric shaft 310, and the connecting rod 630 can move to the left side.

[0189] If the eccentric shaft 310 further rotates, the Figure 6 position in (a) of Figure 6 and the position in (b) of

[0190] will be repeated, and the connecting rod 630 can reciprocate left and right.

[0191] As a result, the power transmission unit 400 combined with the connecting rod 630 can also reciprocate left and right, so that the hanger unit 700 combined with the power transmission unit 400 and the clothes placed on the hanger unit 700 can also shake.

[0192] Figure 7 Another embodiment of the moving clothes hanger 100 of the clothes processing apparatus of the present invention is shown.

[0193] The moving clothes hanger 100 of the new embodiment may also include a power transmission unit 400, and the power transmission unit 400 is disposed on the upper part of the inner housing 10 and is configured to shake the clothes hanger 900.

[0194] A hanger part 700 on which the clothes hanger 900 can be placed or rested may be provided below the power transmission part 400.

[0195] Thus, if the power transmission part 400 moves, the hanger part 700 moves, and the clothes hanger 900 placed on the hanger part 700 shakes, thereby being able to show the effect of shaking the clothes.

[0196] A plurality of the power transmission parts 400 may be provided, and a plurality of the hanger parts 700 combined with the power transmission parts 400 may also be provided. Thus, a large number of clothes corresponding to the number of the power transmission parts 400 can be placed inside the inner housing 20 and renovated.

[0197] The mobile clothes hanger 100 may further include a driving part 200 that provides power for the power transmission part 400 to move.

[0198] If the driving part 200 can transmit power to the power transmission part 400, it may also be arranged to be exposed to the inside of the inner housing 20. However, since the driving part 200 is arranged to receive electric energy to operate, it is preferably blocked from being exposed to steam or hot air.

[0199] Therefore, the driving part 200 may be configured 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.

[0200] The power transmission part 400 may penetrate through the upper part of the inner housing 20 and receive the power of the driving part 200. The power transmission part 400 may penetrate through the upper part of the inner housing 20 and extend downward, with its lower end being exposed to the accommodation space 21.

[0201] The power transmission part 400 may be arranged in a rod shape, a tube shape, a plate shape, etc. with a length greater than the thickness.

[0202] On the other hand, the upper surface of the inner housing 20 may be arranged to support the loads of the power transmission part 400 and the driving part 200. However, when the power transmission part 400 places clothes and moves, the load of the driving part 200 is relatively large. Therefore, the clothes processing device 1 of the present invention may further have a support part 800 to stably arrange the mobile clothes hanger 100 on the upper surface of the inner housing 20.

[0203] The support part 800 may be arranged on the upper part of the inner housing 20 but is supported by being combined with the box body 1. The support part 800 may be made of a metal material with a shape that is difficult to change.

[0204] The power transmission unit 400 and the driving unit 200 can be disposed on the support unit 800 and arranged on the upper surface of the inner housing 20.

[0205] On the other hand, the driving unit 200 includes a motor that rotates a rotating shaft. The driving unit 200 can be configured to move the power transmission unit 400 by using the power that rotates the rotating shaft.

[0206] However, it is difficult to sufficiently displace and shake the power transmission unit 400 only by the in-situ rotation of the rotating shaft.

[0207] Therefore, the mobile clothes hanger 100 may further include a displacement generating unit 300, which is coupled to the rotating shaft to generate sufficient displacement capable of moving the power transmission unit 400.

[0208] The displacement generating unit 300 can connect the rotating shaft and the power transmission unit 400 to each other and is arranged to transmit the power of the rotating shaft to the power transmission unit 400.

[0209] The displacement generating unit 300 may include an eccentric shaft, which uses the rotating shaft to draw a trajectory larger than the diameter of the rotating shaft and rotates. The eccentric shaft can generate displacement that enables the power transmission unit 400 to reciprocate within a preset range.

[0210] 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.

[0211] The mobile clothes hanger 100 can be arranged to reciprocally rotate the power transmission unit 400 to shake the clothes, rather than causing the power transmission unit 400 to reciprocate left and right.

[0212] Specifically, the mobile clothes hanger 100 can be arranged to reciprocally rotate the power transmission unit 400 within a preset angular range, rather than causing it to linearly reciprocate.

[0213] Thus, the power transmission unit 400 can be arranged to reciprocally rotate left and right at a specified position, causing the clothes placed on the power transmission unit 400 to only reciprocally rotate left and right without reciprocating left and right.

[0214] As a result, even if the clothes rotate inside the inner housing 20 by using the power transmission unit 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.

[0215] The mobile clothes hanger 100 may further include a reciprocating rotating part 500, which converts the continuous rotational energy generated in the driving part 200 or the displacement generating part 300 into the reciprocating rotational motion of the power transmission part 400.

[0216] The reciprocating rotating part 500 may be arranged to connect the displacement generating part 300 and the power transmission part 400 to each other. The reciprocating rotating part 500 is arranged 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, so as to prevent the clothes from being damaged by the mobile clothes hanger 100.

[0217] On the other hand, the mobile clothes hanger 100 may also be arranged to only reciprocally rotate any one of the plurality of power transmission parts 400.

[0218] However, if only one power transmission part 400 rotates, there is a risk that the clothes placed on the rotating power transmission part may collide with the clothes placed on other power transmission parts 400, causing damage to the clothes or damage to the mobile clothes hanger 100.

[0219] Therefore, the mobile clothes hanger 100 is preferably arranged to rotate all of the plurality of power transmission parts 400. In addition, the mobile clothes hanger 100 may be arranged to rotate the plurality of power transmission parts 400 at the same angle simultaneously. Thus, collisions between the power transmission parts 400 can be prevented.

[0220] 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 beneficial for controlling the rotation of the power transmission parts 400.

[0221] However, if the driving parts 200 are provided in plurality and each transmits power to each power transmission part 400, it will not only cause an excessive load on the upper part of the inner housing 20, but may also lead to the inconvenience of controlling the plurality of driving parts 200.

[0222] Therefore, the mobile clothes hanger 100 may be arranged such that one driving part 200 rotates the plurality of power transmission parts 400.

[0223] At this time, if the displacement generating part 300 and the reciprocating rotating part 400 are connected to respectively transmit the power transmitted from one driving part 200 to all the power transmission parts 400, it may make the configuration and structure of the displacement generating part 300 and the reciprocating rotating part 400 complicated and reduce their reliability.

[0224] Therefore, the mobile clothes hanger 100 of the present invention can be configured to transmit the power generated in the driving part 200 to only a part of the plurality of power transmission parts 400.

[0225] The reciprocating rotation part 500 can be configured to transmit the power transmitted from the driving part 200 or the displacement generation part 300 to only a part of the power transmission parts 400.

[0226] Therefore, the structure of the reciprocating rotation part 500 becomes simple, thereby ensuring the reliability of power transmission.

[0227] On the other hand, the mobile clothes hanger 100 may further include a connection part 600, and the connection part 600 is configured to transmit the power transmitted to a specific power transmission part 400 to another power transmission part 400.

[0228] For example, the connection part 600 can be configured to connect the plurality of power transmission parts 400 to each other. Thus, if any one of the power transmission parts 400 rotates, the power transmission parts 400 adjacent to or separated from it can all rotate.

[0229] Specifically, the mobile clothes hanger 100 can be configured to transmit the power of the driving part 200 to only any one of the plurality of power transmission parts 400, and transmit the power transmitted to the power transmission part to other power transmission parts 400 through the connection part 600.

[0230] The displacement generation part 300 or the reciprocating rotation part 400 can be configured to concentrate and transmit the power generated in one driving part 200 to one power transmission part 400. In addition, the connection part 600 can transmit the power transmitted to a specific power transmission part 400 to all the power transmission parts 400.

[0231] The connection part 600 can be configured to rigidly connect all the power transmission parts 400, and all the power transmission parts 400 can be configured to rotate simultaneously in the same direction and at the same angle by using the connection part 600.

[0232] Thus, the mobile clothes hanger 100 of the present invention can use a simple structure to make the plurality of power transmission parts 400 reciprocate and rotate simultaneously or synchronously at the same angle by using one driving part 200.

[0233] Figure 8 The structure of the mobile clothes hanger 100 is shown.

[0234] The mobile clothes hanger 100 may include a driving unit 200, a plurality of reciprocating rotating units 500, and a connecting unit 600. The driving unit 200 is fixed to the upper part of the inner housing 20 and provides power to move the power transmission unit. A plurality of the reciprocating rotating units 500 are respectively combined with a plurality of the power transmission units 400, receive the power from the driving unit 200, and rotate in a manner of repeatedly switching the rotation direction. The connecting unit 600 is arranged to connect the plurality of reciprocating rotating units to each other.

[0235] The connecting unit 600 may include a singular link that connects the plurality of reciprocating rotating units 500 to rotate the plurality of reciprocating rotating units integrally.

[0236] The connecting unit 600 may also be arranged to connect the plurality of power transmission units 400.

[0237] If the connecting unit 600 is arranged to connect the plurality of reciprocating transmission units 500, the connecting unit 600 may be arranged at a position closer to the upper part than the support unit 800, so that the connecting unit 600 does not expose into the inner housing 20.

[0238] If the connecting unit 600 is a singular link, interference between the driving unit 200 and the connecting unit 600 can be minimized.

[0239] For example, the singular link may be combined in front of or behind the reciprocating rotating unit 500, and the later-described displacement generating unit 300 or the driving unit 200 may be arranged behind or in front of the reciprocating rotating unit 500.

[0240] The connecting unit 600 may be arranged to reciprocate in the width direction of the inner housing 20 and rotate the plurality of reciprocating rotating units 500.

[0241] 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. 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.

[0242] The motor 210 may be configured to be fixed to the upper part of the inner housing 20 and rotate the rotary shaft 220. However, the rotary shaft 220 is configured to rotate at a speed faster than the appropriate cycle for reciprocally rotating the power transmission unit 400 by the motor 210. If the RPM of the rotary 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.

[0243] To solve such a problem, the transmission unit 230 may be configured to transmit the output of the rotary shaft 220 as it is to the power transmission unit 400, or may transmit it after reducing the RPM of the rotary shaft 220.

[0244] The transmission unit 230 is configured to rotate by being connected to the rotary shaft 220, but may be configured to have a diameter larger than that of the rotary shaft 220. Thus, the transmission unit 230 may be configured to transmit the torque of the rotary shaft 220 while rotating more slowly than the RPM of the rotary shaft 220.

[0245] The power shaft 240 may be configured to rotate by using the transmission unit 230, may be separately provided from the rotary shaft 230, and is a configuration for directly transmitting power to the power transmission unit 400.

[0246] The reciprocating rotation unit 500 may be configured to be combined with the power transmission unit 400 and be able to rotate together with the power transmission unit 400.

[0247] 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.

[0248] The reciprocating lever 510 may be configured in a rib or rod shape whose rotation center is combined with the support shaft 410.

[0249] 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 configured to be connected to the transmission unit 230 to receive the power of the motor 210.

[0250] The reciprocating lever 510 may be configured to reciprocally rotate at a preset angle if the transmission unit 230 rotates by using the motor 210. The power transmission unit 400 may be configured to be combined with the rotation center of the reciprocating lever 510 and rotate together with the reciprocating lever 510.

[0251] A plurality of reciprocating levers 510 may be arranged to be connected by a connecting unit 600.

[0252] The connecting portion 600 may be configured to connect one end of a plurality of reciprocating levers 510.

[0253] Thus, as long as any one of the plurality of reciprocating levers 510 rotates, the connecting portion 600 can be moved so that the plurality of reciprocating levers 510 can rotate simultaneously and synchronously.

[0254] The power transmission portion 400 and the reciprocating lever 510 may be supported by the support portion 800. In addition, the motor 210 and the transmission portion 230 may also be supported by the support portion 800.

[0255] Figure 9 It shows that the mobile clothes hanger 100 of the present invention is separated from the inner housing 20.

[0256] The power transmission portion 400 may be configured to extend from the upper part to the lower part of the inner housing, and the hanger portion 700 may be coupled to the lower part of the power transmission portion 400.

[0257] The reciprocating rotation portion 500 may be coupled to each power transmission portion 400, and may be coupled to the upper part of the power transmission portion 400 to be easily connected to the driving portion 200.

[0258] A plurality of the power transmission portions 400 and the reciprocating rotation portions 500 may be provided, and may be arranged at a preset distance apart in the width direction of the inner housing.

[0259] The connecting portion 600 is configured to connect a plurality of the power transmission portions 400 or a plurality of the reciprocating rotation portions 500 to each other. Thus, the connecting portion 600 may be configured to rotate a plurality of the power transmission portions 400 or a plurality of the reciprocating rotation portions 500 as a whole simultaneously.

[0260] The power transmission portion 400 may include a support shaft 410 that penetrates the upper part of the inner housing 20 and is coupled to the reciprocating lever 510.

[0261] The support shaft 410 may penetrate the support portion 800 and be exposed to the upper part of the support portion 800 or the upper part of the inner housing 20.

[0262] The power transmission portion 400 may include an auxiliary support portion 420 that is coupled to the support shaft 410 and exposed to the accommodation space. The auxiliary support portion 420 may be configured in a rod shape, and the hanger portion 700 is coupled and fixed to the lower part thereof.

[0263] The auxiliary support portion 420 can be set 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 combined with the support shaft 410 can also rotate to cause the hanger portion 700 to rotate left and right.

[0264] The reciprocating lever 510 can include a main lever 511 that directly receives power from the driving portion 200 to reciprocally rotate, and an auxiliary lever 512 that receives power from the main lever 511 through the connecting portion 600.

[0265] The main lever 511 can be set to be singular and set to directly receive power from the driving portion 200.

[0266] In the driving portion 200, the motor 210 can include a vertical motor 211 combined with the support portion 800 and a vertical rotating shaft 221 that rotates by using the vertical motor 211.

[0267] The transmission portion 230 can include a power pulley 231, a transmission pulley 232, and a belt 233. The power pulley 231 is combined with the vertical rotating shaft 221 and rotates together with the vertical rotating shaft 221. The transmission pulley 232 is combined with the power shaft 240 to cause the power shaft 240 to rotate. The belt 233 connects a part of the outer peripheral surfaces of the power pulley 231 and the transmission pulley 232.

[0268] The transmission portion 230 can 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 can be set to support the transmission pulley 232 so that the transmission pulley 232 is arranged side by side with the power pulley 231, and can be set to be placed on the support portion 800.

[0269] The power shaft 240 can be set to transmit the power transmitted from the rotating shaft 220 to one end of both ends of the main lever 511.

[0270] The power shaft 240 can be combined with a later-described displacement generating portion 300 to cause the main lever 511 to reciprocally rotate around the support shaft 410.

[0271] The connecting portion 600 can include a connecting bar 610 that connects the end portion of the main lever 511 that is not connected to the power shaft 240 at both ends and one end of the auxiliary lever 512.

[0272] The auxiliary lever 512 can be rotatably coupled to the support shaft 410 and can be configured to extend in one direction from the portion coupled to the support shaft 410 and connect to the connecting rod 610.

[0273] The connecting rod 610 can 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 can be arranged side by side with respect to the connecting rod 610 or in the width direction.

[0274] The connecting rod 610 can be configured as a single unit and can be configured to cause the main lever 511 and the auxiliary lever 512 to rotate simultaneously and synchronously about their respective support shafts 410.

[0275] The inner housing 20 can have a through-hole 23, and a part of the support portion 800 is disposed in the through-hole 23 to expose the power transmission portion 400 to the accommodation space 22.

[0276] The through-hole 23 can be provided on the upper surface 22 of the inner housing, and the through-hole 23 can be provided in the direction in which the power transmission portion 400 is disposed.

[0277] For example, the power transmission portions 400 can be arranged at intervals from each other in the width direction of the inner housing, and the through-hole 23 can be arranged in the width direction of the inner housing.

[0278] The laundry treating apparatus 1 of the present invention can further include a support frame 12 disposed outside the inner housing and supporting the cabinet 1.

[0279] The support frame 12 can be arranged at each position corresponding to the corner of the cabinet 1 or the corner of the inner housing 20 and can be made of a metal material that maintains the appearance of the laundry treating apparatus. Both ends of the support portion 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 housing.

[0280] Figure 10 An exploded perspective view of the mobile clothes hanger 100 of the present invention is shown.

[0281] The power transmission portion 400 can include a support shaft 410, an auxiliary support portion 420, and a hanger portion 700. The support shaft 410 penetrates 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 exposed to the accommodation space 21. The hanger portion 700 is coupled to the auxiliary support portion 420 and is configured to support the hanger portion 900 or clothes.

[0282] The support shaft 410 is provided in the shape of a long cylinder with a length greater than its diameter, and can be easily rotated by the reciprocating lever 510.

[0283] 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.

[0284] The cross-sectional area of the auxiliary support portion 420 can be larger than that of the support shaft 410, and the length can 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 clothes hanger portion 900 and enable their rotation can be ensured.

[0285] The support portion 800 may include a support plate member 810, and the support plate member 810 may be provided to allow the support shaft 410 to penetrate and support the drive portion 200. The support plate member 810 may be composed of a metal plate, so rigidity and durability can be ensured, and the support plate member 810 may extend along the direction in which a plurality of the power transmission portions 400 are arranged.

[0286] The support portion 800 may include extension bodies 812 extending upward from both ends of the support plate member 810 and a placement body 813 extending from the extension body 821 and placed on the support frame 12, so as to form a space for placing the drive portion 200 and the reciprocating rotation portion 500 between the upper parts of the inner housing 20 and the box body 10.

[0287] The support portion 800 may include a shaft coupling portion 820 provided to allow the support shaft 410 to penetrate.

[0288] 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 portions 400 are arranged, and the shaft coupling portions 820 may be arranged at intervals along the length direction of the support plate member 810.

[0289] On the other hand, the support portion 800 may further include an auxiliary plate member 880 coupled to the lower part of the support plate member 810. The auxiliary plate member 880 may be made of a resin series and may be provided to be able to accommodate a part of the outer peripheral surface of the power transmission portion 400.

[0290] The auxiliary plate member 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 at the lower part of the support plate member 810 to accommodate the power transmission part 400 to enable it to 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 member 810, and may be combined and fixed to the support plate member 810.

[0291] The accommodation holes 882 may be arranged 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 discharging to the shaft coupling part 820. The extension steps 883 may serve to disperse the load or impact transmitted to the auxiliary plate member 880, and may serve to prevent the accommodation holes 882 from colliding with or interfering with the hanger part 900.

[0292] The support part 800 may further include a placement plate part 820 disposed on the upper part of the support plate member 810.

[0293] The placement plate part 820 may serve to support the bearing disposed at 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 member 810.

[0294] 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 member 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.

[0295] 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.

[0296] The main lever 511 and the auxiliary lever 512 may be arranged to be combined with their respective support shafts 410 and rotate about the support shafts 410 as the rotation centers.

[0297] 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, and the connecting hook 612 protrudes from the connecting body 611 and is rotatably disposed on the main lever 511 and the auxiliary lever 512.

[0298] The reciprocating lever 510 may include a connecting bearing 513 that combines with one end of the main lever 511 and one end of the auxiliary lever 512 and supports the connecting hook 612 to enable rotation.

[0299] If the connecting rod 610 rotates left and right, the main lever 511 or the auxiliary lever 512 may reciprocate left and right.

[0300] The reciprocating rotating part 500 may further include a support bearing 530 that can support the support shaft 410 or the reciprocating lever 510 to enable rotation.

[0301] The support bearing 530 can accommodate the support shaft 410 to enable rotation, and the support bearing 530 can be arranged at the shaft coupling part 620.

[0302] The reciprocating lever 510 may be arranged above the support bearing 530.

[0303] The support bearing 530 may also be stacked in a plurality of layers, or may be set as a ball bearing or an oil-free bearing.

[0304] The placement plate part 860 may be arranged 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.

[0305] In addition, the auxiliary plate member 880 may also be arranged to be configured below the support bearing 530 to block the exposure of hot air or moisture from the outer peripheral surface of the support bearing 530.

[0306] Figure 11 The operation mode of the mobile clothes hanger 100 of the present invention is shown.

[0307] Refer to Figure 11 In (a) of, the main lever 511 may include a main body 5111 that combines with the support shaft 410 and combines with the connecting rod 610.

[0308] The main body 5111 may include a main central hole 5115 that combines with the support shaft 410 and enables the support shaft 410 to rotate, and the main body 5111 may be arranged to extend from the main central hole 5115 to both sides.

[0309] One end of the main body 5111 may be provided with a main receiving hole 5112 for receiving power from the driving part 200, and the other end may include a main transmission hole 5113 for placing and combining the connecting rod 610.

[0310] The main body 5111 may further include a stepped portion 5114 that extends from the central hole toward the main receiving hole 5112 but forms a step. The main body 5111 may, under the action of the stepped portion 5114, dispose one end of the main body 5111 or the main transfer hole 5113 at a position closer to the lower part than the main central hole 5115.

[0311] 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 transfer portion 230.

[0312] 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 transfer hole 5123 coupled to the connecting rod 610.

[0313] The auxiliary body 5121 may be set to have a length shorter than that of the main body 5111.

[0314] The distance from the main central hole 5115 to the main transfer hole 5113 may be set to be the same as the distance from the auxiliary central hole 5125 to the auxiliary transfer hole 5123.

[0315] The connecting rod 610 may be disposed above the auxiliary transfer hole 5123 and the main transfer hole 5113 to connect the auxiliary lever 512 and the main lever 511 to each other.

[0316] Refer to Figure 11 As shown in FIG. (b), the driving unit 200 may be configured to insert the power shaft 240 into the main receiving hole 5112. Thus, the driving unit 200 may be configured to directly rotate the power shaft 240 to rotate the main receiving hole 5112 left and right.

[0317] 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.

[0318] To this end, the mobile clothes hanger 100 of the present invention may include a displacement generating unit 300 that is coupled to the power shaft 240 and generates a displacement greater than the rotation radius of the power shaft 240.

[0319] The displacement generating unit 300 may be configured to convert the in-situ rotational movement of the power shaft 240 into a displacement movement that reciprocates within a preset range. The displacement movement may be transmitted to the reciprocating rotation unit 500 to cause the power transmission unit 400 to rotate reciprocally.

[0320] For example, the displacement generating unit 300 may further include an eccentric shaft 310 extending from the power shaft 240 and rotating along a trajectory with a preset radius.

[0321] The diameter of the eccentric shaft 310 may 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.

[0322] However, the preset radius at which the eccentric shaft 310 rotates may be set to be larger 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 the main center hole 5115 as a reference.

[0323] 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.

[0324] 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.

[0325] The power transmission unit 400 may be provided with threads along the circumference on the upper part of the support shaft 410.

[0326] The main transmission hole 5113 and the auxiliary center hole 5125 can be directly fixed to the support shaft 410 by using a wire thread or the like.

[0327] However, the power transmission unit 400 may further include a transmission coupling portion 415. After the support shaft 410 passes through the main transmission hole 5113 and the auxiliary center hole 5125, the transmission coupling portion 415 is threadedly coupled to the support shaft 410 to fix the support shaft 410 to the main transmission hole 5113 and the auxiliary center hole 5125.

[0328] Therefore, the support shaft 410 and the reciprocating lever 510 are coupled by the transmission coupling portion 415, enabling the support shaft 410 and the reciprocating lever 510 to rotate simultaneously.

[0329] Figure 12 Shows the operation process of the mobile clothes hanger 100 of the present invention.

[0330] 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)

[0331] 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 part 400 coupled to the main center hole 5115 can rotate counterclockwise.

[0332] 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)

[0333] 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)

[0334] If the auxiliary lever 512 rotates counterclockwise, the power transmission part 400 coupled to the auxiliary center hole 5125 also rotates counterclockwise. (⑤)

[0335] 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)

[0336] 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.

[0337] 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)

[0338] If the connecting rod 610 moves to the left, the auxiliary receiving hole 5123 in the auxiliary lever 512 rotates clockwise 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 clockwise. (④)

[0339] If the auxiliary lever 512 rotates clockwise, the power transmission part 400 coupled to the auxiliary center hole 5125 also rotates clockwise. (⑤)

[0340] 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.

[0341] While the connecting rod 610 reciprocally moves left and right, the auxiliary lever 512 can be reciprocally rotated, so that the power transmission part 400 coupled to the auxiliary lever 512 can reciprocally rotate.

[0342] 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.

[0343] Therefore, the auxiliary lever 512 and the main lever 511 can reciprocally rotate at the same angle by using the connecting rod 610. As a result, all the power transmission parts 400 can simultaneously and synchronously rotate at the same angle, and the reciprocally rotating angles can also be the same as each other.

[0344] 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.

[0345] 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 levers 512 can be disposed in any arrangement or order.

[0346] Figure 13 The operation mode of the mobile clothes hanger of the present invention is shown.

[0347] Refer to Figure 13 In (a) of, the power transmission part 400 can rotate to the right through the reciprocating rotation part 500 when the driving part 200 operates. At this time, all the plurality of power transmission parts 400 connected to the connection part 600 can also rotate to the right.

[0348] Refer to Figure 13In (b) thereof, 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 of the plurality of power transmission units 400 connected to the connection unit 600 can also rotate to the left.

[0349] If this process is repeated, the power transmission unit 400 can be rotated left and right.

[0350] 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.

[0351] 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.

[0352] 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 and does not move its position.

[0353] Refer to Figure 13 In (c) thereof, the hanger portion 900 may include a hook portion 910 placed on the hanger portion 700 and a placement portion 900 coupled to the hook portion 910. A surface portion 950 for preventing clothes from slipping may be provided on the surface of the placement portion 950.

[0354] The placement portion 950 may be symmetrically arranged left and right with the hook portion 910 as the center. The hanger portion 900 may be placed on the hanger portion 700 so that the placement portion 950 is arranged in the front-back direction.

[0355] 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 may be the same as the rotation angle (θ) of the right side of the placement portion 950, and the moving distance of the left side of the placement portion 950 may be the same as the moving distance of the right side of the placement portion 950.

[0356] 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, and thus can cancel each other out.

[0357] Similarly, although the power transmission unit 400 rotates to the right, as a result, the weight and force moving to the left with respect to the hanger unit 900 are the same as those moving to the right, so they can cancel each other out.

[0358] As a result, even if the power transmission unit 400 rotates, the multiple forces applied to the hanger unit 900 can cancel each other out. Consequently, the vibration force, exciting force, or inertial force generated by the hanger unit 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.

[0359] As a result, even if the drive unit 200 drives with maximum output, the entire mobile hanger 100 or the entire laundry processing apparatus 1 will not generate significant vibration.

[0360] Alternatively, the surfaces of the clothes placed on the hanger unit 900 rotate left and right and vibrate respectively, so that a greater dust removal force can be ensured.

[0361] 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.

[0362] 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.

[0363] 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.

[0364] That is, the power transmission unit 400 can be arranged to reciprocally rotate at a preset angle less than one revolution while being fixed at the rotation center.

[0365] Even if the power transmission unit 400 rotates rapidly, the position of the power transmission unit 400 remains fixed.

[0366] Therefore, the vibration and noise generated by the power transmission unit 400 inside the inner housing 20 can be minimized.

[0367] Figure 14 A system in which the mobile hanger operates is shown.

[0368] The clothes processing device of the present invention may include a control unit C, and the control unit C drives one or more of the moving clothes hanger 100, the steam generating unit 50, and the heat pump system 80 to execute any program for processing the clothes.

[0369] The control unit C may execute various programs composed of a series of control methods capable of performing renovation operations such as drying, deodorizing, sterilizing, and wrinkle removal on the clothes.

[0370] The clothes processing device 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 device. The input unit I and the display unit D may be provided on either the cabinet 10 or the door 11.

[0371] When the control unit C receives an instruction to execute the program from the input unit I or the like, or when it receives an instruction to input the power supply, the control unit C may operate the moving clothes hanger 100.

[0372] The control unit C may operate the moving clothes hanger 100 by driving the driving unit 200. The driving unit 200 may be arranged to receive an instruction from the control unit C, operate the transfer unit 300, and shake the clothes.

[0373] The control unit C may be arranged to provide a signal for directly driving the driving unit 200 and also receive information from the driving unit 200.

[0374] The clothes processing device of the present invention may include a current detection unit 260, and the current detection unit 260 receives electrical information such as output current and voltage from the driving unit 200 and transmits it to the control unit C.

[0375] In addition, the clothes processing device of the present invention may include a position sensing unit 270. After sensing the position of the power transmission unit 400 or the connecting unit 600, the position sensing unit 270 transmits it to the control unit C. The position sensing unit 270 may be arranged to sense the rotation angle of the rotating shaft 220 and the power shaft 240 or the position of the eccentric shaft 310.

[0376] The clothes processing device of the present invention may be arranged to sense clothes information including any one or more of the weight, length, material, property, and type of the clothes based on a control system for driving the moving clothes hanger 100. The clothes processing device of the present invention may optimize and adjust one or more of the intensity, type, time, and option values of the renovation program for processing the clothes according to the sensed clothes information.

[0377] For example, the clothing treatment device of the present invention can operate by adjusting any one or more of the driving speed of the moving clothes 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 heating pump 80 according to the sensed clothing information.

[0378] The driving speed of the moving clothes hanger 100 can be defined by either the driving rpm of the driving unit 200 or the speed at which the power transmission unit 400 moves.

[0379] The driving speed of the moving clothes hanger 100 can be defined based on the speed at which the clothes shake or the speed at which the upper end of the clothes shakes.

[0380] The clothing treatment device of the present invention can differently adjust the mechanical force applied to the clothes, the amount and exposure time of the steam supplied to the clothes, and the temperature and exposure time of the hot air supplied to the clothes according to the sensed clothing information.

[0381] Thus, the clothing treatment device of the present invention can perform matching processing on the clothes according to the clothing information, rather than still executing a unified program regardless of the clothing information.

[0382] Of course, the clothing treatment device of the present invention can have an additional sensing unit for sensing the clothing information. For example, the clothing treatment device of the present invention can be set to provide a load sensor on the moving clothes hanger 100 to sense the weight of the clothes, and can use a radar sensor or the position sensing unit 270 through light, radio waves, etc. inside the inner housing to sense the length, material, type, etc. of the clothes.

[0383] However, if a plurality of sensing units for directly sensing the clothing information are provided in the clothing treatment device, not only will the production and repair costs increase, but due to the characteristics of supplying hot air and steam to the inside of the clothes, it may be difficult to maintain the durability of the sensing units.

[0384] For this reason, the clothing treatment device of the present invention can be set such that the control unit C performs arithmetic operations on the electronic information applied to or output from the moving clothes hanger 100 while driving the moving clothes hanger 100.

[0385] The electronic information can include any one or more of the current value, power value, waveform, amplitude, and period of the current or power applied to or output from the motor unit 210 while driving the driving unit 200.

[0386] Generally, in washing machines, dryers, etc., the weight of the laundry is calculated by analyzing the current value output from a drive unit that rotates a drum containing the laundry. This is because the laundry contained in the washing machine and dryer becomes possible to form into a mass inside the drum regardless of the type, material, and length of the laundry. In other words, the washing machine and dryer can determine the current value required when the drive unit rotates or the current value output from the drive unit according to the weight of the laundry regardless of the state of the laundry, and there are almost no variables that affect the current value.

[0387] However, in the laundry processing apparatus of the present invention such as a clothes care machine, the laundry is only placed on the upper part of the moving hanger 100, and the other parts are arranged in the accommodation space 21 in an extended state. As a result, if the moving hanger 100 is driven, the laundry vibrates in the height direction while forming various waveforms and vibrating.

[0388] In other words, the vibration of the laundry is independent of the vibration of the moving hanger 100, and thus the vibration generated by the laundry or acts as a load on the moving hanger 100.

[0389] The amplitude or vibration form generated by the laundry affects the current value and power value applied to or output from the drive unit 200.

[0390] As a result, in the laundry processing apparatus of the present invention, if the weight of the laundry is simply sensed only by the electronic information while driving the moving hanger 100, its reliability may be significantly reduced.

[0391] For example, as the laundry is set to different lengths, even if it vibrates at the same frequency, the vibration waveform or amplitude is formed differently. In addition, although the weights of the laundry are the same, when the lengths of the laundry are different from each other, when each laundry shakes at the same frequency, the vibration waveforms or amplitudes of each laundry may also be different from each other. As a result, although the motor 210 of the drive unit 200 is driven at the same speed, if the lengths of the laundry 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 laundry are different from each other.

[0392] If the moving hanger 100 is driven slowly, the upper part to the lower part of the laundry can move and sway integrally with the moving hanger 100. However, if the moving hanger 100 is driven quickly, the upper part of the laundry starts to sway with a larger amplitude and period, but the lower part of the laundry cannot follow the vibration of the upper part of the laundry or follows late due to the inertial force, and thus situations such as bending and twisting of the laundry may occur.

[0393] Furthermore, when the driving frequency of the mobile 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 hanger 100 than when it does not vibrate in the form of a stationary wave, which may cause a large error in the electronic information of the driving unit 200.

[0394] 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 hanger 100, thereby providing an effect that changes the electronic information of the driving unit 200.

[0395] In summary, when driving the mobile 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.

[0396] Therefore, the clothing processing device of the present invention can be set to calculate clothing information including any one or more of the weight and length of the clothing, taking into account not only the weight of the clothing but also the vibration characteristics of the clothing according to the driving speed of the driving unit 200 or the power transmission unit 400.

[0397] Figure 15 An embodiment is shown in which the control unit of the clothing processing device of the present invention accurately calculates clothing information using a mobile hanger.

[0398] The clothing processing device of the present invention operates the mobile hanger 100 by driving the driving unit 200 by the control unit C.

[0399] The driving unit 200 can continuously rotate the rotating shaft 220 and the power shaft 240 in one direction and reciprocally move the power transmission unit 400 through the transmission unit 300 to shake the clothing.

[0400] 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.

[0401] In other words, regardless of the embodiment in which the mobile hanger 100 is set, the mobile hanger 100 provided in the clothing processing device of the present invention can also control the driving unit 200 to reciprocate the power transmission unit 400.

[0402] In the clothing processing device of the present invention, when the mobile hanger 100 is driven, regardless of the operation mode of the driving unit 200 and the transmission unit 300, the power transmission unit 400 can also change the moving direction of the hanger unit 700 twice in each cycle.

[0403] Whenever the moving direction of the hanger unit 700 and the clothing placed on the hanger unit 700 through the hanger part 900 is changed, a corresponding inertial force will be generated. Thus, the hanger unit 700 transmits the inertial force to the power transmission unit 400 twice in each reciprocating cycle.

[0404] If the hanger unit 700 reciprocates, the driving unit 200 not only receives the load for moving the power transmission unit 400, but also receives the inertial force. Each time the driving unit 200 periodically receives the inertial force, it will bear an additional load.

[0405] As a result, since the inertial force is generated by the clothing according to a preset cycle while the driving unit 200 is driving, the electronic information output from the driving unit 200 or the electronic information received through the driving unit 200 may include a curve graph capable of knowing the motion state of the hanger unit 700.

[0406] Therefore, the control unit C of the clothing processing device of the present invention can calculate clothing information including the vibration characteristics of the clothing by analyzing the electronic information itself and the inertial force of the clothing that can be sensed in the electronic information.

[0407] Furthermore, the control unit C can identify the cycle of the reciprocating movement of the hanger unit 700 and the time point when the moving direction of the hanger unit 700 changes by sensing the inertial force applied to the driving unit 200.

[0408] In addition, the control unit C can also sense the magnitude of the inertial force and the change in the magnitude of the inertial force to sense the motion state of the clothing.

[0409] For example, in the clothing processing device 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.

[0410] The DC component, as an electrical signal having an absolute value with a preset quantity, 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 may analyze the DC component to obtain the information required for calculating the weight of the clothing.

[0411] The AC component, as an electrical signal having a preset period, may include information reflecting the vibration characteristics of the clothing. During the process of the clothing vibrating or during the process of the hanger unit 700 periodically changing the movement direction, the inertial force may be transmitted to the driving unit 200, and the transmitted inertial force may be reflected as the AC component.

[0412] The control unit C may obtain the information required for calculating the vibration characteristics of the clothing, the vibration period of the clothing, etc. by analyzing the AC component.

[0413] In the case where the AC component has a preset period as described above, the second harmonic has the clearest signal characteristics in the periodic curve, and it has reliability information related to the period information. Therefore, the control unit C may 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.

[0414] According to the length and material of the clothing, the vibration characteristics of the clothing may be different. Therefore, the vibration characteristics include clothing information related to the length and material of the clothing. Thus, the control unit C may calculate clothing information such as the length and material of the clothing by using the vibration characteristics analyzed through the analysis of the AC component.

[0415] Furthermore, the control unit C may additionally track and sense the change in the electronic information of the driving unit 200 by changing the driving speed of the driving unit 200 or the power transmission unit 400. Thus, it is possible to confirm the previously sensed clothing information and recalculate the clothing information.

[0416] As a result, when driving the driving unit 200, the control unit C may 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.

[0417] Figure 16 An embodiment of calculating the weight of the clothing of the clothing treatment apparatus of the present invention is shown.

[0418] Refer to Figure 16In (a) of the present invention, in the laundry treatment apparatus of the present invention, the long clothing L can be disposed inside the accommodation space 20 in a state of being placed on the moving hanger 100.

[0419] Referring to Figure 16 In (b) of the present invention, the moving hanger 100 of the laundry treatment apparatus of the present invention can drive the driving 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.

[0420] The moving hanger 100 can be driven at a specific frequency to shake the clothing supported by the power transmission unit 400.

[0421] 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 at a specific frequency periodically. In addition, in order to drive the power transmission unit 400 at a specific frequency, the driving 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.

[0422] If the moving hanger 100 starts to be driven at a low frequency, the long clothing L can reciprocate with the power transmission unit 400. During this process, although the upper end of the clothing L can move together with the power transmission unit 400, the farther away from the power transmission unit 400, the more the clothing L tends to remain stationary under the action of inertia. As a result, the lower part of the clothing moves more laggingly than the upper end of the clothing, and the lower end of the clothing L moves in the most lagging state in the clothing L.

[0423] In addition, when the power transmission unit 400 stops to change the moving direction, although the upper end of the clothing L stops together with the power transmission unit 400, the lower end of the clothing remains in a moving state under the action of inertia. As a result, the lower part of the clothing moves farther than the power transmission unit 400 from the upper part to the lower part, and the lower end of the clothing moves the most.

[0424] If the moving hanger 100 or the driving unit 200 is driven at a low frequency to make the power transmission unit 400 reciprocate relatively slowly, the amplitude of the reciprocating movement of the lower end of the clothing can be greater than the amplitude of the reciprocating movement of the upper end of the clothing.

[0425] In this case, if the driving frequency of the mobile clothes hanger 100 or the driving unit 200 increases, the power transmission unit 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.

[0426] In addition, if the power transmission unit 400 moves, the inertial force generated by the entire 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 unit 400 changes the moving direction.

[0427] Refer to Figure 16 (c) of, if the mobile clothes hanger 100 or the driving unit 200 is driven at a faster frequency, the reciprocating speed of the power transmission unit 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.

[0428] In addition, the displacement gradually increases from the upper part to the lower part of the clothes. When coupled with the displacement of the reciprocating movement of the power transmission unit 400, there will be intervals in which the clothes move in different directions from the upper part to the lower part, and the clothes form a waveform and vibrate.

[0429] If the clothes vibrate, the vibration energy is transmitted to the mobile clothes hanger 100 and acts as an additional load applied to the driving unit 200.

[0430] In addition, if the mobile clothes hanger 100 is driven at a faster frequency, the clothes will form more waveforms and vibrate. As a result, the clothes L do not move in the same direction as a whole, but move in different directions from the upper part to the lower part and vibrate the whole clothes.

[0431] In other words, if the driving unit 200 is driven from low speed to acceleration and driven at a speed above a specific speed, the entire clothes L cannot move in the same direction, and the moving directions are different from each other, causing the clothes to form a twisted waveform and twist.

[0432] The twisting of the clothes L can be defined as indicating positions on the clothes L where the moving direction or the amplitude direction is different from each other.

[0433] If the driving unit 200 is driven at a speed above the speed at which the clothes L deforms, the clothes L form 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 mobile clothes 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 mobile clothes hanger 100.

[0434] If the power transmission unit 400 reciprocates more quickly, more nodes n and antinodes a are formed in the clothing L.

[0435] In addition, if the moving clothes 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.

[0436] The vibration of the clothing in the form of a standing wave means that when the clothing vibrates, the positions of the nodes n that seemingly remain stationary on the clothing do not change over time, and the positions of the antinodes a that vibrate with the maximum amplitude on the clothing also do not change over time.

[0437] The standing wave is generated whenever the moving clothes 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 regions where the nodes n are formed and the regions where the antinodes a are formed in the clothing may not change.

[0438] When the vibrations occurring in the clothing cancel each other out in cases where their amplitude directions are different from each other, not all of them may be transmitted to the moving clothes hanger 100. If the clothing vibrates in the form of a standing wave, the vibration forms generated in the clothing can be symmetrically formed 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 clothes hanger 100 can be minimized to the greatest extent.

[0439] Figure 17 The change in the vibration form of the clothing according to the driving frequency of the moving clothes hanger is shown.

[0440] Refer to Figure 17 In (a) of, when the moving clothes 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 clothes 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 amplitudes of the regions.

[0441] The fundamental frequency can be defined as the driving frequency of the moving clothes hanger 100 at which waveforms or vibrations start to be generated in the clothing.

[0442] If the moving clothes hanger 100 is driven at a frequency below the fundamental frequency, no waveforms are generated in the clothing, so the clothing as a whole can move in the same direction.

[0443] As the driving speed of the driving unit 200, the first speed may be defined as the speed at which the moving clothes hanger 100 is driven at the fundamental frequency. When the driving unit 200 drives from a stationary state to the first speed at which the clothes L starts to twist, the moving direction of the entire clothes L may be the same.

[0444] In other words, the amplitude of the upper end of the clothes and the amplitude of the lower end of the clothes may be different, but the moving direction of the power transmission unit 400 and the moving direction of the entire clothes may be the same as each other.

[0445] Referring to Figure 17 of (b), if the moving clothes hanger 100 is driven at a frequency higher than the fundamental frequency, twisting may occur in the clothes L. Additionally, if the moving clothes hanger 100 is driven at a resonance frequency faster than the fundamental frequency, the clothes L may vibrate in the form of a standing wave.

[0446] Whenever it is equivalent to n times the minimum resonance frequency, the clothes may form a standing wave and vibrate. Therefore, the minimum frequency at which the moving clothes hanger 100 can first make the clothes vibrate in the form of a standing wave may be defined as the minimum resonance frequency.

[0447] When the moving clothes hanger 100 is driven at the minimum resonance frequency, the driving speed of the driving unit 200 may be defined as the second speed. The second speed may be set to be faster than the first speed. The second speed may be defined as the minimum resonance speed.

[0448] If the driving unit 200 is driven at a speed equal to or higher than the first speed, twisting may occur in the clothes L. As a result, different regions with different vibration directions may be formed in the clothes L in the height direction.

[0449] If the driving unit 200 is driven at the second speed, the reciprocating period of the moving clothes hanger 100 may correspond to the reciprocal of the resonance frequency of the clothes L, and the clothes L may vibrate in the form of a standing wave.

[0450] If the clothes L vibrates in the form of a standing wave, the position of the node n, which is the region in the clothes L that does not vibrate, is fixed, and the position of the antinode a, which is the region with the maximum amplitude, is also fixed.

[0451] When the driving unit 200 is driven at the second speed to generate a first-order standing wave in the clothes L, there is one node n formed, and the antinode a may be formed to be one more than the node n including the upper end of the clothes.

[0452] In other words, if the driving unit 200 is driven at the second speed, the clothes may sway at the first resonance frequency f1 and vibrate in the form of a first-order (n = 1) standing wave.

[0453] 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.

[0454]

[0455] 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.

[0456] 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).

[0457] In formula (1), v is related to the tension and linear density of the clothing and can be determined by the fiber characteristics of each piece of clothing. l represents the length of the clothing.

[0458] 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).

[0459] Refer to Figure 17 of (c), the mobile clothes hanger 100 can be driven at a frequency up to twice the minimum resonance frequency.

[0460] As a result, the driving speed of the driving unit 200 is increased to twice, reducing the vibration period of the power transmission unit 400 to half. As a result, the clothing can form a standing wave of f2 equivalent to twice the first resonance frequency and vibrate.

[0461] 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.

[0462] That is, the clothing L can vibrate in the form of a second-order standing wave (n = 2). In the second-order standing wave (n = 2), there are two nodes n and three antinodes a on the clothing L.

[0463] When the clothing L vibrates in the form of a second-order standing wave (n = 2), 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).

[0464] Therefore, if the driving frequency of the mobile clothes hanger 100 is determined as a multiple of the resonance frequency, it can be controlled so that the regions where the clothing generates the maximum amplitude are different.

[0465] Using this, the laundry treating apparatus of the present invention can concentrate the energy generated in the moving hanger 100 on a specific area of the laundry. In addition, the moving hanger 100 can switch the specific area of the laundry and perform concentrated vibration by changing the frequency. Accordingly, the laundry treating apparatus of the present invention can more powerfully shake off dust or foreign matter attached to the laundry.

[0466] Refer to Figure 17 of (d), the moving hanger 100 can be driven at a frequency up to three times the minimum resonance frequency.

[0467] When the moving 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.

[0468] The driving unit 200 can be driven at a speed up to three times the second speed when the laundry vibrates in the form of a first-order standing wave, and the period of the power transmission unit 400 can be shortened to 1 / 3.

[0469] As a result, the laundry vibrates at a resonance frequency of f3, forms a third-order standing wave (n = 3) and vibrates, so that three nodes n and four antinodes a can be formed in the laundry L. When the laundry 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 laundry L vibrates in the form of a first-order standing wave (n = 1) and when the laundry L vibrates in the form of a second-order standing wave (n = 2). In addition, the interval between the nodes n is shorter than before.

[0470] 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 at a resonance frequency up to twice the minimum resonance frequency.

[0471] The laundry treating apparatus of the present invention can set more areas where the laundry vibrates and vibrate them uniformly, or set fewer areas where the laundry vibrates and vibrate them concentratedly by adjusting the frequency of the moving hanger 100.

[0472] Refer to Figure 17 of (e), 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 laundry vibrates in the form of a first-order standing wave, the reciprocating period of the power transmission unit 400 is shortened to 1 / 4.

[0473] 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.

[0474] In this way, when the mobile clothes 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.

[0475] As a result, the clothes vibrate at the resonance frequency of f4, and the clothes L vibrate in the form of a fourth-order standing wave (n = 4). The clothes L can vibrate to form four nodes n and five antinodes a. When the clothes L vibrate 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 clothes L vibrate in the form of a first-order standing wave (n = 1), when the clothes L vibrate in the form of a second-order standing wave (n = 2), and when the clothes L vibrate in the form of a third-order standing wave (n = 3).

[0476] In addition, the interval between the nodes n and the nodes n can be shortened compared to before. If the amplitudes of the power transmission unit 400 are the same, the amplitudes of the antinodes a can be formed to be the same.

[0477] If the driving unit 200 drives faster, the intervals between the plural nodes n formed in the clothes can be shortened, and the formation positions of the plural nodes n can also be different.

[0478] As described above, if the mobile 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 clothes L can vibrate in the form of a standing wave proportional to the n multiple.

[0479] According to Equation (1), the resonance frequency at which the clothes vibrate in the form of a standing wave is different according to the length of the clothes. In addition, the driving speed or driving RPM of the driving unit 200 that can make the clothes vibrate in the form of a standing wave is also determined as a unique value (characteristic value) for each piece of clothes.

[0480] On the other hand, the clothes processing apparatus of the present invention can be set to distinguish whether the clothes vibrate irregularly or vibrate in a manner of forming a standing wave.

[0481] When the driving frequency of the mobile clothes hanger 100 is increased, if the driving frequency is consistent with the resonance frequency of the clothes placed thereon, the vibration characteristics of the clothes are different from those when no standing wave is formed.

[0482] In other words, when the clothes do not vibrate in the form of a standing wave, the change in their vibration is linear or the change amount of the vibration is predictable, while when the clothes vibrate in the form of a standing wave, their vibration characteristics are different from those when vibrating at the previous frequency and those when vibrating at the subsequent frequency, and will change sharply.

[0483] Utilizing this characteristic, the control unit C can sense that the frequency of the corresponding mobile 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.

[0484] For example, when the clothes vibrate at the resonance frequency, the current value or power value sensed by the driving unit 200 may instantaneously reach a peak.

[0485] Or, when the clothes vibrate in the form of a standing wave, compared with when they do not vibrate in the form of a standing wave, their vibration may be significantly reduced, and less vibration may be transmitted to the mobile clothes hanger 100. Thus, the control unit C can sense that the corresponding frequency is the resonance frequency of the clothes placed thereon through a sharp reduction in the load applied to the driving unit 200.

[0486] Or, the control unit C can utilize Figure 15 the method described in to sense 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 driving unit 200 to sense in real time whether the clothes vibrate 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 singular point where at least any one of the waveform, amplitude, and period of the second harmonic changes sharply.

[0487] In addition, the control unit C can sense whether the clothes vibrate at the resonance frequency by grasping the change in the driving speed of the driving unit 200 when the clothes vibrate 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 driving unit 200 when the clothes vibrate at the resonance frequency and when the clothes vibrate at a frequency different from the resonance frequency.

[0488] 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.

[0489] In addition, actually even when the clothes do not 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 driving unit 200 when the clothes vibrate with a pre-stored table or data.

[0490] In addition, the control unit C can confirm whether the sensed resonance frequency is equivalent to the actual resonance frequency. For example, the control unit C can confirm whether the changes sensed by the above method are periodically shown when driving the mobile clothes hanger 100 at a frequency that is a multiple of the sensed resonance frequency.

[0491] As a result, the control unit C can calculate and sense one or more of the resonance frequency of the clothing, the driving speed of the driving unit 200 for vibrating the clothing at the resonance frequency, the RPM of the driving unit 200, and the reciprocating period of the power transmission unit 400 through the moving hanger 100.

[0492] Hereinafter, an embodiment of a control method for accurately sensing the weight of the clothing by using the vibration characteristics of the clothing of the present invention will be described.

[0493] On the other hand, if the clothing L vibrates and nodes n are formed on the clothing, the vibration generated at a position closer to the lower part than the nodes n may not be completely transmitted to the moving hanger 100.

[0494] In addition, if the clothing L vibrates in the form of a standing wave, the positions of the nodes n are always fixed. Therefore, the vibration generated in the clothing L is blocked by the nodes n and may not be completely transmitted to the moving hanger 100.

[0495] In addition, as the clothing L vibrates in the form of a standing wave with a larger multiple, the intervals between the nodes n and the nodes n become shorter and shorter, making the total amount of vibration energy of the clothing remaining between the respective nodes smaller. As a result, the position of the node closest to the moving hanger 100 also gradually approaches the moving hanger 100 as the clothing vibrates in the form of a larger standing wave, thereby transmitting smaller vibration or inertial force to the moving hanger 100.

[0496] 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 moving hanger 100 varies depending on the position where the nodes n are generated in the clothing L, the interval between the nodes n adjacent to the moving hanger 100 and the moving 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 moving hanger 100, the clothing treatment device of the present invention needs to minimize or block the vibration generated in the clothing.

[0497] To this end, the clothing treatment device of the present invention can be set to calculate the weight of the clothing while driving the moving hanger 100 at a frequency lower than the resonance frequency at which a standing wave is generated in the clothing.

[0498] In addition, the clothing treatment device of the present invention can be set to calculate the weight of the clothing while driving the moving hanger 100 at a frequency lower than the fundamental frequency (period) at which the clothing starts to generate a waveform or vibration.

[0499] 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 placed on the moving clothes hanger 100 vibrates in the form of a standing wave when calculating the weight of the clothing.

[0500] 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.

[0501] Specifically, the control unit C of the clothing treatment device of the present invention can increase the driving frequency of the moving clothes hanger 100 in the range from the speed at which the moving clothes hanger 100 is stationary to the second speed, and sense the weight of the clothing through the electronic information applied or output to the driving unit 200.

[0502] 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 within a range below the first speed and sense the weight of the clothing.

[0503] That is, the control unit C can drive the moving clothes hanger 100 within a 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 be able to analyze the load applied to the driving unit 200 to calculate the weight of the clothing.

[0504] The control unit C calculates 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 and dryers, etc., or can also directly adopt the method described in Figure 15 In the description.

[0505] 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 moving clothes hanger 100 can also be controlled differently.

[0506] For example, when the clothing treatment device of the present invention senses the weight of the clothing, it drives the moving clothes hanger 100 at a frequency below the basic frequency, but when executing any program for treating the clothing, it can drive the moving 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 objects from the clothing or expose it more evenly to the supplied steam and hot air.

[0507] The clothing treatment device of the present invention can set the maximum frequency for driving the moving clothes hanger 100 differently according to the weight of the clothing. The clothing treatment device of the present invention can, when supplying one or more of the steam and the hot air to the inner casing 20, control the maximum frequency for driving the moving clothes hanger 100 differently according to the weight of the clothing.

[0508] For example, even if the moving clothes hanger 100 is driven at the same frequency, more vibrations may occur as the weight of the clothing increases. Therefore, the maximum frequency at which the moving clothes hanger 100 is driven can be set lower as the weight of the clothing increases.

[0509] For example, if the clothing is heavier, more hot air or steam needs to be supplied to the clothing to complete processes such as drying, deodorizing, sterilizing, and dehumidifying the clothing. Therefore, the clothing treatment device of the present invention can control the steam generating unit 50 so that when it senses that the weight of the clothing is heavier, the injection amount of the steam supplied to the inner casing is more than when it senses that the weight of the clothing is lighter, or the injection time of the steam is longer than when it senses that the weight of the clothing is lighter. In addition, the clothing treatment device 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 greater 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.

[0510] Figure 18 An embodiment is shown in which the clothing treatment device of the present invention controls the moving clothes hanger by sensing the weight and resonance frequency of the clothing.

[0511] The clothing treatment device of the present invention can determine the optimum frequency (Optimum Hz) at which the moving clothes hanger 100 can be driven 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 vibrations 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 outside the cabinet 10.

[0512] Therefore, the clothing treatment device of the present invention drives the moving clothes hanger 100 at the optimum frequency (Optimum Hz), and thus can apply sufficient physical force to the clothing while reducing the vibrations generated in the clothing treatment device.

[0513] On the other hand, as described above, in the case where the clothing is driven at the resonance frequency, it vibrates in such a way that the antinodes and nodes are fixed, so that a specific area of the clothing can be concentrated, and the vibrations or inertial forces transmitted from the clothing can be minimized to the greatest extent.

[0514] Therefore, during the execution of any program for treating clothes, the clothes treating apparatus of the present invention can drive the moving clothes hanger at a resonance frequency that causes the clothes to vibrate in the form of a standing wave in at least a part of the section.

[0515] That is, although the clothes treating apparatus of the present invention drives at an optimum frequency (OptimumHz) corresponding to the weight of the clothes, in at least a part of the section, the moving clothes hanger 100 can be driven at a resonance frequency to cause the clothes to vibrate in the form of a standing wave. Thereby, while minimizing the vibration generated in the clothes, a concentrated physical force can be transmitted to a specific area of the clothes.

[0516] In addition, the clothes treating apparatus of the present invention can drive the moving clothes hanger 100 at two or more resonance frequencies to cause the clothes to vibrate in two or more forms of standing waves. Thereby, the area where the clothes vibrate intensively is changed, and thus a concentrated physical force can be sequentially applied to the whole clothes. Therefore, the foreign matter removal effect of the clothes and the exposure effect of steam and hot air can be maximally improved.

[0517] In addition, the control unit C can cause the moving clothes hanger 100 to be repeatedly driven at the optimum frequency and the resonance frequency. Thereby, while minimizing the vibration transmitted to the cabinet 10, a specific area of the clothes can be intensively shaken.

[0518] In addition, the control unit C can drive the moving clothes hanger 100 at a first resonance frequency that causes the clothes to vibrate in the form of a standing wave within a first time period, and can drive the moving clothes hanger 100 at a second resonance frequency that causes the clothes to vibrate in another form of standing wave within a second time period. The control unit C can also completely omit driving the moving clothes hanger 100 at the optimum frequency.

[0519] The first time period and the second time period can be the same as each other.

[0520] 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.

[0521] In addition, the control unit C can drive the moving clothes hanger 100 at a first resonance frequency that causes the clothes to vibrate in the form of a standing wave within a first time period, can drive the moving clothes hanger 100 at a second resonance frequency that causes the clothes to vibrate in another form of standing wave within a second time period, and can drive the moving clothes hanger 100 at the optimum frequency within a third time period.

[0522] Herein, the first resonance frequency, as a frequency capable of driving the clothes at a resonance frequency, can be any frequency that is n times the minimum resonance frequency.

[0523] In addition, as another frequency that can drive the clothing at the resonance frequency, the second resonance frequency can be any frequency equivalent to (n + 1) times the minimum resonance frequency.

[0524] Specifically, the control unit C determines the optimal frequency for driving the mobile clothes hanger according to the sensed weight of the clothing. During program execution, the mobile clothes hanger 100 can also be driven at a resonance frequency closest to the optimal frequency in at least a part of the interval.

[0525] That is, even when driving the mobile clothes hanger 100 at the resonance frequency, the control unit C can drive the mobile clothes hanger 100 at a resonance frequency closest to the optimal frequency, maximally suppressing the vibration transmitted from the clothing and stably shaking the clothing.

[0526] 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 clothing L also change.

[0527] The control unit can drive the mobile clothes hanger 100 at a resonance frequency (High Hz) higher than the optimal frequency (Optimum Hz) and a resonance frequency (Low Hz) lower than the optimal frequency in at least a part of the interval during program execution.

[0528] The control unit can repeatedly drive the mobile clothes hanger 100 at a resonance frequency (High Hz) higher than the optimal frequency (Optimum Hz) for a preset time and drive the mobile clothes hanger 100 at a resonance frequency (Low Hz) lower than the optimal frequency for a preset time.

[0529] 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 optimal frequency, and then drive the mobile clothes hanger 100 at a low resonance frequency (Low Hz), and repeat this process.

[0530] Refer to Figure 18 In (b) of, if the mobile clothes hanger 100 is driven at a resonance frequency (Hihg Hz) higher than the optimal frequency, the clothing 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 optimal frequency, the clothing can vibrate as shown in the left figure.

[0531] Using this, the control unit C can repeat the following process: After driving the driving unit 200 at a preset time to vibrate the clothing in the left form, increase the driving speed of the driving unit 200 to vibrate the clothing in the right form at a preset time, and then reduce the driving speed of the driving unit 200 again to vibrate the clothing in the left form.

[0532] In this way, the control unit C can change the position of the antinode a formed on the clothing by changing the driving speed or driving period of the mobile hanger 100, so that the dust removal force can be appropriately distributed on the clothing. After changing the positions of the nodes n and antinodes a formed on the clothing L, the control unit C can fix the positions of the nodes n and antinodes a again, so that foreign matters in other areas can be concentrated and separated again.

[0533] The time when the driving unit 200 is driven at various multiples of the second speed can be set longer than the time when the driving unit 200 accelerates or decelerates.

[0534] Figure 18 (b) shows that the control unit C accelerates or decelerates the mobile hanger 100 at two resonance frequencies, but this is only an embodiment, and the control unit C can drive the mobile hanger 100 at three or four or more resonance frequencies to accelerate and decelerate it step by step.

[0535] 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 clothing is minimized.

[0536] For example, during the period when the control unit C vibrates the clothing at other frequencies than the resonance frequency, when the clothing generates excessive vibration, the control unit C can drive the mobile hanger 100 at a frequency equivalent to the resonance frequency to suppress the vibration of the clothing L.

[0537] For example, during the period when the control unit C drives the clothing at the optimal frequency, when the clothing generates excessive vibration, the control unit C can drive the mobile hanger 100 at a frequency equivalent to the resonance frequency to suppress the vibration of the clothing L.

[0538] Figure 19 Shows the process of the clothing processing device of the present invention sensing the weight of the clothing through the mobile hanger.

[0539] The clothing processing device of the present invention can provide a control method including a sensing step A of sensing the clothing 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 closes, and a driving step S of driving the mechanical chamber 30 to process the clothing.

[0540] The sensing step A may include a weight sensing step A1 for sensing the weight of the clothing, and the weight sensing step A1 may include a step in which the control unit C drives the moving clothes hanger 100 and calculates the weight of the clothing by using the electronic information applied to or output from the moving clothes hanger 100.

[0541] In the weight sensing step A1, the control unit C may sense the weight of the clothing while driving the driving unit 200 at a first speed V1 within a first time t1.

[0542] The first speed V1 in the driving speed of the driving unit 200 may be defined as a speed at which the clothing does not twist, and the second speed V2 may be defined as the minimum speed at which the clothing vibrates at a resonance frequency.

[0543] The first speed V1 may be the minimum speed at which the clothing will never twist.

[0544] The control unit 100 may 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 the error associated with the vibration of the clothing L is maximally excluded from the electronic information, the control unit C can accurately calculate the weight of the clothing only by driving the moving clothes hanger 100.

[0545] The sensing step A may include an acceleration step A2 capable of sensing the resonance frequency of the clothing.

[0546] In the acceleration step A2, the control unit C may sense the clothing vibrating in the form of a standing wave by increasing the speed of the moving clothes hanger 100 to a speed higher than 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 may be regarded as a step in which the control unit C senses the second speed, and may be regarded as a step in which the minimum speed of the driving unit 200 that drives the clothing in the form of a standing wave is sensed.

[0547] In the acceleration step A2, the control unit C may 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.

[0548] On the other hand, in the driving step S, the control unit C may drive the driving unit 200 at a processing speed faster than the first speed and the second speed. Therefore, the sensing step A may be a step of driving the moving clothes hanger 100 at a speed lower than the driving step B within a preset time.

[0549] 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 moving clothes hanger 100 driven in the driving step S according to the clothes information sensed in the sensing step A.

[0550] 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.

[0551] For example, in the driving step S, the control unit C can 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 standing wave occurs in the clothes. K can be any natural number. That is, the control unit C can arbitrarily change the value of K and drive the clothes L at various forms of resonance frequencies.

[0552] For example, the control unit C can raise the driving speed of the driving unit 200 again, 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 clothes.

[0553] Figure 20 Another embodiment showing the process of the clothes processing apparatus of the present invention sensing the weight of clothes by a moving clothes hanger is shown.

[0554] Although the first speed is the speed at which the clothes do not twist, it is differently set according to the material or length of the clothes. 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 clothes.

[0555] Therefore, if the clothes processing apparatus of the present invention executes the weight sensing step A1, it can gradually accelerate from the state where the driving unit 200 is stationary to sense the interval corresponding to the first speed.

[0556] The control unit C can drive the driving unit 200 so that the clothes accelerate from the stationary state to the speed at which they twist or the speed at which the clothes vibrate in the form of a standing wave.

[0557] During the process of raising the driving speed of the driving unit 200, the control unit C can define the speed below the speed at which it senses that the clothes twist or the clothes vibrate in the form of a standing wave as the first speed.

[0558] In addition, the control unit C may perform the following steps: during the process of increasing the driving speed of the driving unit 200, when it senses that the clothing is twisted or the clothing vibrates in the form of a standing wave, 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 is twisted or the clothing vibrates in the form of a standing wave.

[0559] 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.

[0560] Alternatively, the control unit C may drive the mobile clothes hanger 100 again at a speed below the first speed V1, and analyze the electronic information of the driving unit 200 to calculate the weight of the clothing.

[0561] In addition, the control unit C may increase the driving speed of the driving unit 200 to above the second speed V2 in the acceleration step A2 to check whether the second speed V2 is the minimum resonance speed at which the clothing vibrates in the form of a standing wave.

[0562] For example, the control unit C may sense the resonance frequency of the clothing by checking whether the clothing L vibrates in the form of a (k - 1)-order standing wave at the second speed V2 and the speed (Vk) corresponding to k times the second speed in the acceleration step A2. K may be any natural number.

[0563] If the driving step S is performed after the sensing step A, the control unit C may shake the clothing by accelerating the driving unit 200 to the maximum speed (Vmax), and then decelerate or accelerate to the speed range corresponding to the multiple of the second speed, so as to stagewise concentrate on shaking a specific area of the clothing.

[0564] To prevent the driving unit 200 from being overloaded, the driving speed of the driving unit 200 may be stagewise reduced in the driving step S from the third speed, the fourth speed, the nth speed, etc. corresponding to the multiple of the second speed.

[0565] Figure 21 It is a diagram illustrating the principle by which the clothes processing apparatus of the present invention can sense the length of the clothing.

[0566] Figure 21 (a) shows that when the long clothing L is placed on the mobile clothes hanger 100, the driving unit 200 drives at a specific speed greater than the second speed V2. Figure 21Part (b) of [reference] shows that when a piece of clothing L shorter than the long clothing L is placed on the moving clothes hanger 100, the driving unit 200 drives at the same specific speed as when the long clothing L is placed on the moving clothes hanger 100.

[0567] According to Equation (1), the resonance frequency is inversely proportional to the length of the clothing. Therefore, the short clothing L has a resonance frequency greater than that of the long clothing L, and the moving clothes hanger 100 needs to be driven at a faster speed to enable the short clothing L to form a standing wave of the same order.

[0568] Referring to Figure 21 Part (a) of [reference], the specific speed can 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.

[0569] Referring to Figure 21 Part (b) of [reference], when the short clothing L is placed, the driving unit 200 can also drive at the same speed. In other words, Figure 21 In part (b) of [reference], the driving unit 200 can also drive at a driving speed capable of forming a fourth-order standing wave in the long clothing L.

[0570] In the case of the short clothing L, the driving speed can 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 resonance frequency different from that of the long clothing L.

[0571] The clothes processing device of the present invention can also utilize the property that the clothes have different resonance frequencies according to their lengths, and drive the moving clothes hanger 100 to sense the length of the clothes.

[0572] Figure 22 An embodiment is shown in which the clothes processing device of the present invention senses not only the weight of the clothes but also the length.

[0573] The control method of the clothes processing device of the present invention may include a length sensing step A2 of also sensing the length of the clothes in the sensing step A. That is, the acceleration step A2 can be regarded as including the length sensing step A2.

[0574]

[0575] Referring to Equation (1) described above, the resonance frequency (fn) that causes the clothes to vibrate in the form of a standing wave is inversely proportional to the length of the clothes. 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 clothes cannot be accurately sensed.

[0576]

[0577] Referring to the formula (2), 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.

[0578] When the clothing is the same, the linear density (m) is a constant value. Therefore, if the control unit C senses the weight of the clothing and the resonance frequency (fn), the length (l) of the clothing can be determined.

[0579] For this purpose, the control unit C can directly calculate the weight of the clothing through the electronic information of the driving unit 200 in the weight sensing step A1, sense one or more resonance frequencies that can make the clothing vibrate in the form of a standing wave while changing the driving speed of the driving unit 200 in the length sensing step A2, and can calculate the length of the clothing using the weight of the clothing and the resonance frequency.

[0580] 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.

[0581] 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.

[0582] 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 higher than the second speed at which the clothing first vibrates at the resonance frequency.

[0583] The speed range lower than the second speed may include the first speed, and the driving unit 200 can be driven at a speed faster than the second speed in the driving range s.

[0584] Referring to Figure 22 , the control unit C can perform the sensing step A of sensing the clothing information.

[0585] The control unit C may, during the sensing step A, drive the driving unit 200 at the first speed V1 within the first time t1, and simultaneously perform a weight sensing step A1 of calculating the weight of the clothing through electronic information including the current applied to or output from the driving unit 200.

[0586] When the weight sensing step A1 ends, the control unit C may perform a length sensing step A2 of sensing the length of the clothing during the sensing step A.

[0587] The length sensing step A2 may be performed in a speed range faster than the weight sensing step A1, and may be performed in a speed range including a second speed or a resonance speed V2 that generates a first resonance frequency.

[0588] In addition, the length sensing step A2 may be performed within a second time t2, driving the driving unit 200 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 may be set to be longer than the first time t1.

[0589] On the other hand, the control unit C may gradually increase the speed of the driving unit 200 within the second time and obtain information for calculating the length (l) of the clothing.

[0590] For example, the control unit C may drive the mobile clothes hanger 100 at a second speed or a resonance speed, which is the minimum driving speed for vibrating the clothing in a standing wave form, within the 2-1 time t21 and sense the minimum resonance frequency.

[0591] In addition, the control unit C may further increase the driving speed of the driving unit 200 until the clothing vibrates in a standing wave form. In the case where the clothing vibrates in a standing wave form again, drive the mobile clothes hanger 100 within the 2-2 time t22 to sense other resonance frequencies. Within the 2-2 time t22, the mobile clothes hanger 100 may be driven at a speed twice that of the second speed.

[0592] The control unit C may further increase the driving speed of the driving unit 200 until the clothing vibrates in a standing wave form again, and may repeat this process K times. In the case where the clothing vibrates in a standing wave form again, the mobile clothes hanger 100 may 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.

[0593] As a result, the control unit C can accelerate the driving speed of the driving unit 200 to an interval in which 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 by one or more of the electronic information and the weight of the clothing.

[0594] 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.

[0595] In the driving step S, the moving clothes hanger 100 can be driven within a third time t3, and the third time can be set to be longer than the first time t1 and the second time t2.

[0596] In the driving step S, the moving clothes hanger 100 can be driven at a speed faster than the speed at which the moving clothes hanger 100 is driven in the sensing step A.

[0597] 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 interval including the second speed but faster than the second speed, or can linearly or stepwise change in a speed interval where the driving speed is faster than the second speed.

[0598] Figure 23 An embodiment of the control method of the clothing processing apparatus of the present invention is shown.

[0599] The control method of the clothing processing apparatus of the present invention may include a sensing step A of sensing clothing information and a driving step S of processing the clothing.

[0600] The sensing step A and the driving step S can be executed in sequence, but the sensing step A can 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.

[0601] In the clothing 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.

[0602] 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 in a set amount or for a set time; a cooling step S4 of only driving the air supply fan to cool the clothes and at the same time 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.

[0603] On the other hand, it is preferable to determine the optimal driving speed of the driving unit 100 based on the clothing information sensed in the sensing step A.

[0604] 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 clothing information sensed in the sensing step A.

[0605] For this purpose, it is preferable to execute the sensing step A before the drying step S5.

[0606] In addition, when the moving clothes hanger 100 is driven, if the clothes are separated from the hanger part 700 and fall off, the steam is concentrated and ejected to a specific area of the clothes, so there is a risk of damage to the clothes. Therefore, the moving clothes hanger 100 can be driven from the standby step. In this case, it can be preferable to drive the moving clothes hanger 100 so as to be able to shake off foreign matters, dust and moisture attached to the clothes after the steam step S2.

[0607] Therefore, since the sensing step A is to drive the moving clothes hanger 100 and sense the clothing information including the weight and length of the clothes, it can be executed after the steam step S2 and before the drying step S5.

[0608] On the other hand, the driving unit 200 of the moving clothes hanger 100 is preferably driven at a faster speed than the sensing step in the driving step S. Therefore, the driving unit 200 can be driven at a faster speed than in the sensing step A in the drying step S5.

[0609] If the speed of the driving unit 200 for processing clothes in the driving step S is taken 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 unit 200 is driven in the sensing step A. The processing speed can also be the same as the second speed.

[0610] In addition, the sensing step A can be performed during the standby step S3 and the cooling step S4. Therefore, the driving unit 200 can start driving at the first speed from the standby step S3 or the cooling step S4.

[0611] In the sensing step A, the weight sensing step A1 can be performed first, and then the length sensing step A2 can be performed.

[0612] Therefore, the speed of the driving unit 200 or the vibration of the clothing in the weight sensing step A1 can be less than the speed of the driving unit 200 or the vibration of the clothing in the length sensing step A2.

[0613] In the weight sensing step A1, the driving unit 200 can be driven in a region below the first speed.

[0614] The length sensing step A2 can be performed in a region above a second speed faster than the weight sensing step A1.

[0615] The weight sensing step A1 and the length sensing step A2 can be performed continuously.

[0616] 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.

[0617] Through the sensing step A, the control unit C can drive the mobile clothes hanger 100 in a speed range before the clothes start to shake in the form of a resonance frequency or a standing wave and in a speed range above where the clothes start to shake in the form of a resonance frequency or a standing wave.

[0618] In addition, through the length sensing step A2 in the sensing step A, the control unit C can drive the driving unit 200 in at least two or more speed ranges faster than the second speed.

[0619] Through the weight sensing step A1, the control unit C can be set to drive the mobile clothes hanger in 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.

[0620] Through the length sensing step A2, the control unit C can be set to drive the mobile clothes hanger in 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.

[0621] 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.

[0622] Since the driving speed of the driving unit 200 that causes the clothing to 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 moving clothes hanger 100 at the resonance speed or the second speed or a speed range corresponding to a multiple of the second speed.

[0623] As a result, after driving the steam generating unit 50, the control unit C can drive the driving unit 200 at two or more speed ranges.

[0624] If the sensing step A ends, after the sensing step A, 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.

[0625] 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.

[0626] Through the sensing step A, if one or more of the weight and length of the clothing are different, the control unit C can set the processing speed differently.

[0627] For example, if the weight of the clothing is heavy, the control unit C can set the processing speed to a multiple range of the resonance speed. As a result, a standing wave is formed in the clothing, thereby minimizing the vibration energy generated in the clothing.

[0628] If the weight of the clothing is heavy, the control unit C can 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.

[0629] If the length of the clothing is long, compared with when the length of the clothing is short, the control unit C can set the processing speed to a multiple range of the resonance speed. Thereby, it can be operated so that the dust removal force is evenly distributed over the entire clothing.

[0630] If the length of the clothing is long, the control unit C can 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.

[0631] In addition, if the weight of the clothing is heavy, the control unit C can control the mechanical chamber 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.

[0632] In addition, if the length of the clothing is long, the control unit C can control the mechanical chamber so that the supply amount or supply time of the hot air is greater than when the length of the clothing is short. Thereby, hot air is uniformly supplied to the long clothing, so that the renovation effects of sterilization, deodorization, drying, and wrinkle removal can be ensured.

[0633] If it is sensed in the sensing step A that the clothing is heavy, the duration of the driving step can be set to be longer than when it is sensed that the clothing is light. Therefore, the time for uniformly supplying hot air and steam to the heavy clothing as a whole is extended, so that the renovation effect can be ensured.

[0634] If it is sensed in the sensing step A that the clothing is heavy, in the driving step S, the driving time or driving rpm of the compressor can be set to be greater than when it is sensed that the clothing is lighter. Thereby, hot air is more sufficiently supplied to the heavy clothing as a whole, so that the renovation effect can be ensured.

[0635] If it is sensed in the sensing step A that the clothing is long, the driving step S can be driven in a larger speed range than when it is sensed that the clothing is shorter.

[0636] 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 housing.

[0637] 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 housing so that the clothing changes to an n - multiple of the resonance frequency or an n - multiple of the standing wave and shakes.

[0638] The driving of the compressor 83 in the driving step S is performed after the sensing step A, so it can be regarded that the sensing step A drives the moving clothes hanger 100, but the driving of at least any one of the steam generator 51 and the compressor 83 is blocked.

[0639] Figure 24 Another embodiment of the control method of the clothing processing device of the present invention is shown.

[0640] Hereinafter, it will be described centering on the parts different from Figure 23 the embodiment, and the same parts will be omitted to prevent repeated description.

[0641] 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.

[0642] Therefore, the sensing step A can be performed before the steam step S2.

[0643] 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, this step is a step of preparing for the driving step S as a step where steam has not yet been generated inside the steam generator 51.

[0644] 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.

[0645] In addition, since the steam step S2 can be performed based on information such as the weight, length, and material of the clothes sensed in the sensing step A, the steam step S2 can supply an appropriate amount of steam to the placed clothes.

[0646] Thus, if the clothes are heavier, the control unit C can control the mechanical chamber 30 to make the steam injection amount larger than when the clothes are lighter or the steam injection time longer than when the clothes are lighter. That is, the driving time or driving output of the heater in the steam generator 51 can be set larger. Thereby, steam can be evenly supplied to the whole of the heavy clothes, so as to maximize the renovation effect.

[0647] If the length of the clothes is longer, the control unit C can control the mechanical chamber 30 to make the steam injection amount larger than when the length of the clothes is shorter or the steam injection time longer than when the length of the clothes is shorter. That is, the driving time or driving output of the heater in the steam generator 51 can be set larger. Thereby, steam can be evenly supplied to the whole of the clothes, so as to maximize the renovation effect.

[0648] As a result, if the clothes are sensed to be heavier in the sensing step A, the driving step S can set the driving time of the steam generator 51 longer than when the clothes are sensed to be lighter.

[0649] In addition, if the clothes are sensed to be longer in the sensing step A, the driving step S can set the driving time of the steam generator 51 longer than when the clothes are sensed to be shorter.

[0650] Of course, in this case, the driving of the moving clothes hanger 100 can also be interrupted during the steam step S2. However, in order to evenly inject steam onto the clothes during the steam step S2, the moving clothes hanger 100 can also be driven.

[0651] Figure 25 An embodiment is shown in which the laundry treatment apparatus of the present invention also senses the material and water-containing properties.

[0652] The laundry treatment apparatus of the present invention can drive the moving clothes 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-containing properties of the laundry.

[0653] The laundry treatment apparatus of the present invention can sense one or more of the material and water-containing properties of the laundry in the sensing step A.

[0654] That is, the laundry treatment apparatus of the present invention may further include a material sensing step A3 for sensing the material and water-containing properties of the laundry in the sensing step A.

[0655] The material of the laundry may include the linear density (m) of the laundry. Therefore, the laundry treatment apparatus of the present invention can sense whether the laundry is soft or hard.

[0656] The water-containing property may include whether the laundry is hydrophilic or hydrophobic. Therefore, the laundry treatment apparatus of the present invention can sense whether the laundry is hydrophilic or hydrophobic.

[0657] The control unit C, the mechanical chamber 30, and the moving clothes hanger 100 may function as a sensing unit for sensing laundry information.

[0658] The laundry treatment apparatus of the present invention may have a sensing unit capable of sensing the laundry information, and the sensing unit may be regarded as including the control unit C, the mechanical chamber 30, and the moving clothes hanger 100.

[0659] When driving at least any one of the moving clothes hanger 100 and the steam generation unit 50, the control unit C may be set to sense the state change of the laundry to calculate the material and water-containing properties of the laundry. For example, after sensing the state of the laundry before supplying steam to the laundry and the state of the laundry after supplying steam to the laundry, the state change of the laundry may be sensed to calculate one or more of the material and water-containing properties of the laundry.

[0660] Refer to Figure 25 In (a), the laundry treatment apparatus of the present invention can 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.

[0661] Refer to Figure 25 In (b), the laundry 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 laundry for a preset time.

[0662] The purpose of driving the steam supply unit 50 in the sensing step A is not to supply steam to the clothing, but to guide the change in the state of the clothing. Therefore, the time for driving the steam supply unit 50 in the sensing step A can be set shorter than the time for driving the steam supply unit 50 in the driving step S.

[0663] Refer to Figure 25 As shown in (c), after the driving of the steam supply unit 50 is interrupted, the clothing treatment apparatus of the present invention can further execute one or more of the weight sensing step A1 and the length sensing step A2. Through this, the control unit C can calculate one or more of the material and water-containing performance of the clothing.

[0664] For example, the control unit C can sense the change in the weight of the clothing according to the supply of the steam, so as to sense one or more of the material and water-containing performance of the clothing. If the change in the weight of the clothing is greater, it can be determined that the clothing is hydrophilic. If the change in the weight of the clothing is smaller, it can be determined that the clothing is hydrophobic.

[0665] In addition, the control unit C can utilize the characteristic that the degree of steam absorption by the clothing varies according to the material of the clothing to sense the material of the clothing. For example, the supply of steam to the clothing through 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.

[0666] 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 generating unit 50.

[0667]

[0668] In the length sensing step A2, the control unit C can sense the resonance frequency of the clothing through Equation (1).

[0669] 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.

[0670] Therefore, the control unit C can sense one or more of the material and water content performance of the clothing through one or more of the change in the resonance frequency of the clothing before and after steam supply, the change in the weight of the clothing, and the change in the linear density of the clothing.

[0671] 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 before and after steam supply and the change in the weight of the clothing. 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.

[0672] As a result, the clothing treatment device 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.

[0673] Figure 26 An embodiment of sensing clothing information including the material of the clothing through the sensing step is shown.

[0674] In the clothing treatment device 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 step by step at a speed above the second speed V2 can be executed.

[0675] 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.

[0676] After storing the sensed weight and length of the clothing, the control unit C can supply steam to the clothing. The supply amount of the steam can be fixed as a reference amount.

[0677] 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.

[0678] 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.

[0679] On the other hand, if the steam is supplied, the control unit C may execute the material sensing step A3.

[0680] The material sensing step A3 may include executing the weight sensing step A1 and the length sensing step A2 again after the 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 executing the weight sensing step A1 and the length sensing step A2 again after the steam supply. However, since the step of supplying the steam is necessary for the material sensing, the material sensing step A3 may also include the steam supply step.

[0681] The sensing step A may interrupt the driving of the moving clothes hanger 100 when the steam generating unit 50 is operating.

[0682] 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.

[0683] For example, the types of clothing corresponding to the clothing information are digitized and stored in the control unit C. Thus, the control unit C can determine the material and type of clothing such as the clothing is a "dress made of cotton material" or the clothing is a "scarf made of cashmere material" based on the weight, length, and material of the clothing.

[0684] On the other hand, the clothing processing device of the present invention may execute a re - supply step of re - supplying the 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 the steam was supplied before.

[0685] 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 supply amount of steam in the re - supply step according to the material of the clothing.

[0686] For example, if it is sensed in the material sensing step A3 that the clothing is hydrophilic, the supply amount of steam 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 supply amount of steam may also be increased in the re - supply step.

[0687] After that, the control unit C may execute the material sensing step A3 of the clothing again. Thus, it is possible to check whether the material of the clothing is the same as the result of the previous execution of the material sensing step A3.

[0688] 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.

[0689] However, if it is sensed in the first material sensing step A3 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.

[0690] As a result, in the clothing processing apparatus of the present invention, the material sensing step A3 can be executed multiple times, and it is possible to confirm whether the sensed material of the clothing is correct by spraying steam in different ways to the clothing between each of the material sensing steps A3.

[0691] In other words, the control unit C may drive the moving clothes hanger 100 after driving the steam generator 50, and drive the moving clothes hanger 100 again after driving the steam generator 50 again to calculate the clothing information.

[0692] Thus, the control unit C can drive the moving clothes hanger to calculate the clothing information after driving the steam generator 50, and drive the moving clothes hanger to verify the calculated clothing information after driving the steam generator 50 again.

[0693] The amount of steam supplied to the accommodation space 21 when the steam generator 50 is driven for the first time and the amount of steam supplied to the accommodation space 21 when the steam generator 50 is driven for the second time may be set to be different from each other.

[0694] On the other hand, when driving the moving clothes hanger 100 in the sensing step A, the steam supply may be interrupted. Conversely, when driving the steam generator 50, the driving of the moving clothes hanger 100 may 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 generator 50, and to prevent the degree of the clothing containing steam from changing.

[0695] Figure 27 Another embodiment of sensing the material of the clothing is shown.

[0696] As described above, the sensing step A may include a weight sensing step A1 and a length sensing step A2.

[0697] However, the material sensing step A3 can be set as a step of simultaneously driving the steam generating unit 50 and the moving clothes hanger 100.

[0698] That is, the material sensing step A3 can include driving the moving clothes hanger 100 while driving the steam generating unit 50 to sense changes in the weight of the clothing, the length of the clothing, and the resonance frequency of the clothing, thereby calculating the material of the clothing.

[0699] Thus, the sensing step A can be regarded as being able to simultaneously drive the steam generating unit 50 and the moving clothes hanger 100.

[0700] 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, thereby accurately calculating the material of the clothing.

[0701] 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 moving clothes hanger 100 to calculate clothing information.

[0702] Figure 28 An additional embodiment of the control method of the clothing processing device of the present invention is shown.

[0703] As described above, the clothing processing device of the present invention can execute the sensing step A and the driving step S.

[0704] The driving step S can 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 for a set time of the steam; a cooling step S4 of only driving the air supply fan to cool the clothing 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.

[0705] The control unit C can be set to drive at least one of the steam generator and the moving clothes hanger in the sensing step A to calculate clothing information including one or more of the material of the clothing, properties including hydrophilicity or hydrophobicity, and the type of the clothing.

[0706] In the steam step S2, the amount of steam sprayed onto the clothing may also preferably be set differently according to the weight, length, material, properties, and type of the clothing. This is because the optimal steam supply amount has been determined based on the clothing information.

[0707] For this reason, the clothing treatment apparatus of the present invention may execute the sensing step A before the steam step S2 or at the beginning of the steam step S2. Additionally, the sensing step A may start from the heating step S1.

[0708] The heating step s1 is a state in which water is heated in the steam generator 50 to generate steam, so it may be a step in which steam is not supplied to the accommodation space 21.

[0709] Therefore, the control unit C may execute the weight sensing step A1 and the length sensing step s2 in the heating step S1.

[0710] If the steam step S2 starts, the control unit C may execute the material sensing step A3. Specifically, the material sensing step A3 may be to execute the weight sensing step A1 and the length sensing step s2 after supplying steam to the clothing.

[0711] In the material sensing step A3, the control unit C may drive the moving clothes hanger 100 to calculate the clothing information before driving the steam generating unit 50 or after driving the steam generator.

[0712] 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.

[0713] 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 higher than the speed at which the clothing starts to shake in the form of a resonance frequency or a standing wave.

[0714] 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.

[0715] In the material sensing step A3, the control unit C may drive the driving unit 200 at a speed range before the clothing starts to shake in the form of a resonance frequency or a standing wave and at a speed above the speed at which the clothing starts to shake in the form of a resonance frequency or a standing wave.

[0716] As a result, by performing the sensing step A, the control unit C may drive the mobile clothes hanger before and after driving the steam generator unit 50, respectively.

[0717] The control unit C may sense the weight change of the clothing to calculate the clothing information, or may calculate the clothing information based on the difference in current values output from the driving unit 200.

[0718] In addition, the control unit C may sense the change in the speed of the driving unit 50 that causes the clothing to generate a resonance frequency or a standing wave before and after driving the steam generating unit 50 to sense the clothing information. At this time, the formulas (1) and (2) may be applied.

[0719] If the material sensing step A3 ends, the control unit C may set the amount of steam supplied to the clothing in the steam step S2 based on the clothing information sensed in the sensing step A.

[0720] For example, when it is sensed that the clothing is hydrophilic or closer to hydrophilic, compared with when the clothing is hydrophobic, the control unit C may control to generate more steam in the steam generating unit 50 when performing the steam step S2. Thereby, the clothing can contain more moisture, and thus the renovation effect of the clothing can be maximized.

[0721] On the contrary, when the clothing is hydrophobic, less steam can be generated, thereby saving water and energy while protecting the clothing.

[0722] Furthermore, the control unit C may 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 clothing information sensed in the sensing step A. For example, when it is sensed that the clothing is hydrophilic, compared with when it is hydrophobic, the control unit C may set the driving time or the driving rpm of the compressor to be greater in the drying step S5. Thereby, it is possible to ensure sufficient time for drying the moisture contained in the clothing.

[0723] On the contrary, when the clothing is hydrophobic, it is possible to prevent the clothing from being over-dried by hot air and save energy.

[0724] From another perspective, if it is sensed in the sensing step A that the clothing is hydrophilic, the duration of the driving step S can be set to be longer than when it is sensed that the clothing is hydrophobic. Since hydrophilic clothing contains more moisture, this is to fully shake off dust after it is sufficiently dried.

[0725] If it is sensed in the sensing step A that the clothing is hydrophilic, the driving time of the steam generating unit 50 in the driving step S can be set to be longer than when it is sensed that the clothing is hydrophobic.

[0726] This is to supply more moisture to the hydrophilic clothing, thereby maximizing the renovation effect.

[0727] In addition, if it is sensed in the sensing interval 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.

[0728] In addition, since the sensing step A is performed before the drying step S5 and starts from before the steam step S2, it can be regarded as driving one or more of the moving clothes hanger 100 and the steam generating unit 50 in the sensing step A, but blocking the driving of the compressor 83.

[0729] In the driving step S, if the steam step S2 ends, the moving clothes hanger 100 is driven at the processing speed, so it can be regarded as driving the moving clothes hanger 100 after the steam generating unit 50 operates.

[0730] Figure 29 The structure for the clothing processing apparatus of the present invention to sense clothing information is shown.

[0731] Refer to Figure 29 In the door 11 of the clothing processing apparatus of the present invention, the display unit D can be provided.

[0732] 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 view the state of the display unit D.

[0733] 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 also be set to display the clothing information sensed by the control unit C to the outside.

[0734] The display unit D can display the program information being executed by the control unit C and can be set as a liquid crystal or other type of screen.

[0735] 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.

[0736] Refer to Figure 29 In (b) of, the display unit D can be set 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 forms of numbers, characters, and pictograms.

[0737] Refer to Figure 29 In (c) of, the display unit D can display more detailed information related to the material or properties of the clothing. For example, the display unit D can be set 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 forms of numbers, characters, and pictograms.

[0738] The display unit D can display all of the clothing information D1 to D6, can selectively display, or can alternately display.

[0739] The display unit D can be controlled to immediately display whenever the control unit C senses specific clothing information, and can be controlled to display the clothing information when the control unit C senses all detectable clothing information.

[0740] For example, the control unit C can drive the mobile clothes hanger 100 to sense the weight and length of the clothing before driving the mechanical chamber 30.

[0741] Therefore, the display unit D can be set to display one or more of the weight and length of the clothing before driving the mechanical chamber 30.
