Description

Garment treatment device and method for controlling the garment treatment device

[0001] The present invention relates to a garment treatment device and a control method thereof. More specifically, the present invention relates to a garment treatment device and a control method thereof capable of performing refreshing processes, such as sterilizing, wrinkle removal, deodorizing, and drying, on garments by supplying steam and hot air to the garments.

[0002] In general, a clothing treatment device has emerged that can perform clothing management (refreshment) such as sterilization, deodorization, and drying of clothing by supplying hot air and steam without washing the clothing with water and detergent, like a clothing care machine.

[0003] These garment treatment devices have the advantage of being able to manage clothes without water or detergent, so there is no damage to the clothes, and the time it takes to manage and wear the clothes again is faster than that of clothes treatment using washing machines and dryers.

[0004] Recently, referring to Korean Patent Publication No. 10-2020-0065886, a clothing processing device has been introduced that measures the material and load of clothing inside the inner case by using a light-emitting part inside the inner case where clothing is placed and a light sensor that can detect the light from the light-emitting part.

[0005] This garment treatment device had the advantage of being able to determine the condition of the garment without having to directly contact or connect to the garment through any device or sensor, and of not being limited in determining the load of the garment even when the course is carried out in a sealed state.

[0006] However, since the light emitting part and the sensor part of the above conventional clothing treatment device are arranged in an up-down direction, the light irradiated from the light emitting part is always blocked by the clothing, and therefore there is a fundamental problem in that it is impossible to distinguish between the clothing being placed on the holder and the clothing being removed from the holder.

[0007] When clothes fall off the rack, the surface of the clothes is directly exposed to the steam or hot air emitted, which not only damages the clothes but also prevents the clothes from being refreshed as a whole. However, the problem with conventional clothes treatment devices is that they do not provide any countermeasures against clothes falling.

[0008] Furthermore, even if clothing is of the same weight and material, the method for detecting a drop from the rack and the method for preventing a drop from the rack need to differ depending on whether it is long or short. Furthermore, long clothing is more likely to block the sensor than short clothing, so a method for distinguishing and confirming this is necessary. Nevertheless, these clothing handling devices have a fundamental problem: although they can detect the weight and material of the placed clothing through the light-emitting unit and sensor unit, they cannot distinguish between long and short clothing.

[0009] Therefore, in the case of conventional clothing treatment devices, there was a fundamental problem in that not only could they not distinguish whether the placed clothing was long or short, they could not even detect that the clothing had fallen, and they could not take individual measures for this.

[0010] Furthermore, there was a problem in which users were unable to take active measures after the clothing treatment process was completed because they realized that the clothing had not been properly treated, resulting in low satisfaction with the product.

[0011] The present invention aims to provide a clothing treatment device capable of detecting whether clothing is long or short through a light-emitting device that irradiates light and a sensor unit that detects light.

[0012] The present invention aims to provide a clothing treatment device that can detect when clothing has fallen and prevent the clothing from being damaged by steam or hot air when the clothing has fallen.

[0013] The present invention aims to provide a clothing treatment device capable of detecting and distinguishing between a situation in which long clothes fall from a rack and a situation in which short clothes fall from a rack.

[0014] The present invention aims to provide a garment treatment device that applies different control methods to the courses for treating long garments and short garments.

[0015] The present invention aims to provide a clothing treatment device that can distinguish whether a long garment has fallen from a holder or whether a long garment is vibrating in a holder, even if the long garment interferes with a sensor unit.

[0016] In order to solve the above-described problem, the present invention provides a clothing treatment device that provides a detection method for detecting long clothes.

[0017] The clothing treatment device of the present invention can detect long clothes through a moving hanger that can shake the placed clothes, a light emitting part that can irradiate light into the inside of the inner case, and a sensor part that detects the light from the light emitting part.

[0018] The garment treatment device of the present invention can utilize the fact that when a moving hanger is operated when long garments are placed on it, the vibrations cause interference between light and the long garments, resulting in inconsistent values ​​measured by the light sensor. That is, the garment treatment device of the present invention can detect long garments when the light value detected by the light sensor repeatedly exceeds and falls below a reference value.

[0019] The garment treatment device of the present invention can set the driving RPM to a low speed when operating the moving hanger for detection to prevent long garments from being removed. For example, the detection process can be set to at least one of the lowest driving course RPM, the noise prevention course RPM, and the minimum output RPM capable of operating the moving hanger.

[0020] The clothing treatment device of the present invention can be set to operate by increasing the RPM of the moving hanger for the detection process and dust removal after detection.

[0021] The garment treatment device of the present invention can detect whether a garment is long before steam is sprayed onto the garment. Thus, the garment treatment device of the present invention can prevent damage to the garment caused by steam upon dropping during the detection process, and can also prevent a decrease in detection performance due to reduced vibration caused by moisture absorption from steam in long garments.

[0022] The garment treatment device of the present invention can also drive the moving hanger at a high RPM before or after the long garment detection process, taking into account the dusting effect before the garment is steam-moistened.

[0023] The clothing treatment device of the present invention can be equipped to detect long clothes not only through a light sensor but also through other components such as a moving hanger current value or through user input.

[0024] The clothing treatment device of the present invention can determine that the clothing has fallen if, after detecting that it is a long garment, the value measured by the light sensor during the vibration of the moving hanger remains low for a certain period of time.

[0025] The garment treatment device of the present invention can block the operation of the moving hanger if a long garment falls before or during the steam supply process.

[0026] However, the garment treatment device of the present invention can proceed with the process as is if the long garment falls after steam supply is completed. Instead, the state of the garment falling can be displayed externally.

[0027] The clothing treatment device of the present invention can determine that clothing has not fallen if the light value detected by the light sensor has a fluctuating pattern.

[0028] The clothing treatment device of the present invention can detect a situation in which clothing interferes with a light sensor due to vibration of the clothing caused by the operation of a moving hanger and a blower fan, even if the clothing does not fall in the case of long clothing.

[0029] The clothing treatment device of the present invention can determine that the clothing has fallen if the value measured by the light sensor is lower than a reference value when the clothing is determined to be short.

[0030] The garment treatment device of the present invention can block the operation of the moving hanger until the steam spraying is completed if the placed garment is detected as a long garment. This is done in consideration of the minimal dust removal effect and the risk of malfunction of the light sensor during the steam spraying stage.

[0031] The clothing treatment device of the present invention can control the moving hanger to operate at a stage where steam is not sprayed (e.g., drying stage) when the hung clothing is detected as a long garment.

[0032] The clothing treatment device of the present invention, when detecting that the placed clothing is short, operates a moving hanger at high speed before spraying steam to shake off dust, operates the moving hanger during the steam spraying process to help moisture the clothing, and operates the moving hanger during the waiting / drying stage to remove wrinkles from the clothing.

[0033] In order to solve the above-described problem, the present invention provides a method for controlling a clothing treatment device, including a checking step of determining whether the clothing is a long garment longer than a specific length that interferes with the light sensor, a progress step of processing the clothing by driving at least one of the moving hanger, the compressor, and the steam heater, and a stopping step of stopping the progress step when the light value detected by the light sensor changes.

[0034] In the clothing treatment device of the present invention, if the clothing is determined to be a long garment, the stopping step can be omitted and the progress step can be continued even if the illuminance value detected by the illuminance sensor changes.

[0035] The above inspection step can determine the clothing as long clothing if a change occurs in the illuminance value detected by the illuminance sensor during the process of operating the moving hanger.

[0036] In the above inspection step, the light emitting unit can irradiate the light and drive the moving hanger while at least one of the compressor, the blower fan, and the steam heater is driven.

[0037] The above inspection step can be performed before steam is supplied inside the inner case.

[0038] The garment treatment device of the present invention may include a steam heater that heats water to generate steam, and a second heater having a larger capacity than the first heater. The inspection step may be performed while the first heater and the second heater are operating simultaneously.

[0039] The above inspection step may be performed before driving either the first heater or the second heater.

[0040] The above inspection step may drive the moving hanger at a lower speed than the maximum speed at which the moving hanger is driven in the above progress step.

[0041] The above inspection step may drive the moving hanger at the minimum speed at which the moving hanger operates in the above progress step or at a speed lower than the minimum speed.

[0042] The clothing treatment device of the present invention can perform the stopping step when the clothing is determined to be a long garment and the illuminance value detected by the illuminance sensor remains lower than the reference value for a certain period of time.

[0043] The clothing treatment device of the present invention can perform the stopping step when the illuminance value remains lower than the reference value for a certain period of time when the moving hanger is operated if the clothing is determined to be a long garment.

[0044] The clothing treatment device of the present invention can omit the stopping step after the steam heater is operated even if the illuminance value detected by the illuminance sensor remains lower than the reference value for a certain period of time when the clothing is determined to be a long garment.

[0045] In the garment treatment device of the present invention, if the garment is determined to be a long garment, the progress step can be set to block the operation of the moving hanger until the operation of the steam heater is completed.

[0046] The above progress step can be set to drive the moving hanger when the operation of the steam heater is completed and the compressor is operated.

[0047] If the clothing treatment device of the present invention determines that the clothing is not a long garment, it can continuously drive the moving hanger while the above-described progress step is performed.

[0048] In the case where the clothing treatment device of the present invention determines that the clothing is not a long garment, the driving speed of the moving hanger can be varied in the progress step.

[0049] In order to solve the above-described problem, the clothing treatment device of the present invention can provide a control method of a clothing treatment device including a checking step of driving the moving hanger to determine whether the clothing is a long garment longer than a specific length that interferes with the light sensor, a preparation step of driving the steam heater to prepare the steam to be supplied to the inner case, a spraying step of driving at least one of the first heater and the second heater to supply the steam to the inner case, and a drying step of driving the compressor to dry the clothing with the heated air.

[0050] The above inspection step can be performed in the above preparation step.

[0051] The above inspection step may be completed before the above injection step.

[0052] The clothing treatment device of the present invention may further include a preheating step of supplying the steam to the inner case by driving only one of the first heater and the second heater.

[0053] The above inspection step may be completed before the above preheating step.

[0054] If the clothing is determined to be long clothing in the above inspection step, the moving hanger may be blocked from operating until the end of the spraying step.

[0055] The above moving hanger can start operating in the above drying step.

[0056] In order to solve the above-described problem, the present invention provides a garment treatment device including a cabinet, an inner case provided inside the cabinet to provide a space for accommodating garments, a moving hanger provided to place the garments inside the inner case and shake the garments, a machine room provided below the inner case and including at least one of a heat supply unit for providing heated air inside the inner case and a steam supply unit provided to supply steam inside the inner case, a light emitting unit provided inside the machine room or the inner case to irradiate light, an illuminance sensor disposed on the inner surface of the inner case closer to the machine room than the moving hanger to detect the light, and a control unit for driving at least one of the moving hanger, the heat supply unit, and the steam supply unit to perform a course for treating the garments.

[0057] The above control unit can determine the clothing as long clothing if the illuminance value detected by the illuminance sensor changes while the moving hanger is being driven.

[0058] The above control unit can determine the clothing as long clothing if there is no change in the illuminance value detected by the illuminance sensor while the operation of the moving hanger is stopped.

[0059] The present invention has the effect of detecting whether clothing is long or short through a light-emitting device that irradiates light and a sensor unit that detects light.

[0060] The present invention has the effect of detecting that clothing has fallen and preventing the clothing from being damaged by steam or hot air when the clothing has fallen.

[0061] The present invention has the effect of being able to detect and distinguish between a situation in which long clothes fall from a support and a situation in which short clothes fall from a support.

[0062] The present invention has the effect of applying different control methods for courses for processing long clothing and short clothing.

[0063] The present invention has the effect of being able to distinguish whether the long clothing has fallen from the mounting portion or whether the long clothing is vibrating in the mounting portion, even if the long clothing interferes with the sensor portion.

[0094] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. In this specification, identical or similar components are given identical or similar reference numerals even in different embodiments, and the description thereof is replaced with the first description. The singular expression used in this specification includes plural expressions unless the context clearly indicates otherwise. In addition, when describing the embodiments disclosed in this specification, if a detailed description of a related known technology is judged to obscure the gist of the embodiments disclosed in this specification, the detailed description thereof will be omitted. In addition, it should be noted that the attached drawings are only intended to facilitate easy understanding of the embodiments disclosed in this specification, and the technical ideas disclosed in this specification should not be construed as being limited by the attached drawings.

[0095] Figure 1 illustrates an embodiment of the overall structure of the garment treatment device of the present invention.

[0096] Figure 1(a) illustrates the garment treatment device of the present invention with the door open, and Figure 1(b) illustrates the garment treatment device of the present invention without the door.

[0097] Referring to Fig. 1(a), the garment treatment device of the present invention may include a cabinet (100) forming an exterior and a door (40) rotatably coupled to the cabinet (100).

[0098] An inner case (200) having a storage space (210) for storing clothing may be provided inside the cabinet (100). The inner case (200) may have an opening (210) at the front through which clothing enters and exits, and the opening (210) may be shielded by the door (40).

[0099] The inner case (200) above may be provided with a plastic resin series, and may be provided with a reinforced plastic resin series that does not deform even when exposed to air at a temperature higher than room temperature or heated air (hereinafter, hot air) and steam or moisture.

[0100] The inner case (200) may be provided with a height greater than its width. As a result, the clothing may be accommodated in the accommodation space (210) without being folded or wrinkled.

[0101] The clothing treatment device (1) of the present invention may include a hanger section (500) capable of placing clothing in the receiving space (210) of the inner case (200).

[0102] The above hanger part (500) may be provided as a moving hanger that is provided to shake the clothing inside the inner case (200).

[0103] The above hanger section (500) may be provided in multiple pieces spaced apart along the width direction of the inner case (200) to support a hanger on which clothes are placed. The hanger section (500) may be provided to allow the hanger (590) on which clothes are placed to be secured.

[0104] The clothing treatment device of the present invention may be equipped with a machine room (300) in which various devices capable of supplying at least one of hot air or steam to the receiving space (210) or purifying or dehumidifying the external air of the cabinet (100) are installed.

[0105] The above machine room (300) may be arranged to be separated or partitioned from the inner case (200), but may be provided to communicate with the inner case (200).

[0106] The above machine room (300) can be placed at the bottom of the inner case (200). Thus, when hot air and steam with low specific gravity are supplied to the inner case (200), the hot air and steam can be naturally supplied to the clothing.

[0107] The above-mentioned machine room (300) may include a heat supply unit (340) capable of supplying hot air to the inside of the inner case (200). The heat supply unit (340) may be equipped with a heat pump system or may be equipped with a heater that directly heats air with electric energy.

[0108] In the case where the above heat supply unit (340) is equipped with a heat pump system, it may be equipped to dehumidify and heat the air discharged from the inner case (200) and supply it to the inner case (200). The detailed structure will be described later.

[0109] The above-mentioned machine room (300) may include a steam supply unit (800) capable of supplying steam to the interior of the inner case (200). The steam supply unit (800) may be provided to directly supply steam to the interior of the inner case (200). A detailed structure will be described later.

[0110] To this end, the inner case (200) may be provided with a plurality of through holes (230) penetrating one surface and communicating with the machine room (300). Air in the receiving space (210) may be supplied to the machine room (300) through the through holes (230), and at least one of hot air or steam generated in the machine room (300) may be supplied to the receiving space (200). The through holes (230) may include an inlet hole (231) penetrating the lower surface of the inner case (200) through which air inside the inner case (200) is discharged or sucked into the machine room (300), and an exhaust hole (232) penetrating the lower surface of the inner case (200) through which hot air generated in the machine room (300) is discharged.

[0111] The above discharge hole (232) may be arranged to be offset from the rear surface of the lower surface of the inner case (200). For example, the discharge hole (232) may be arranged to be inclined with respect to the ground between the lower surface or the rear surface of the inner case (200) and to face the hanger portion (510).

[0112] In addition, the inlet hole (231) may be positioned toward the front of the lower surface of the inner case (200). Accordingly, the inlet hole (231) may be positioned apart from the discharge hole (232).

[0113] The above inflow hole (231) may include a first inflow hole (231) penetrating the bottom surface of the inner case, and a second inflow hole (2312) positioned further forward than the first inflow hole (2311).

[0114] A filter can be inserted and placed in the height direction between the first inflow hole (2311) and the second inflow hole (2312).

[0115] The above through hole (230) may include a steam hole (233) through which steam generated from the steam supply unit (800) is supplied. The steam hole (233) may be arranged on one side of the discharge hole (232).

[0116] Meanwhile, a water supply tank (302) capable of supplying water to the steam supply unit (800) and a drain tank (301) for collecting condensate condensed in the heat supply unit (340) may be provided in front of the machine room (300).

[0117] The above water supply tank (301) and the above drain tank (302) can be detachably installed at the front of the machine room (300). Accordingly, the garment treatment device of the present invention can be freely installed without being restricted by a water supply source or a drain source.

[0118] Meanwhile, a drawer (303) that extends forward and has a separate storage space may be further provided in front of the machine room (300). The drawer (303) may store a steam generator or an iron.

[0119] An external device (304) connecting the machine room (300) and the outside may be additionally provided at the bottom of the above cabinet.

[0120] Figure 2 illustrates an example of a moving hanger (500) structure.

[0121] The moving hanger (500) of the garment treatment device of the present invention may include a power transmission unit (530) arranged on the upper portion of the inner case (200) to swing the hanger (590).

[0122] A hanging part (570) on which the clothes hanger (590) can be mounted or placed may be provided at the lower portion of the power transmission part (530). Accordingly, when the power transmission part (530) moves, the hanging part (570) moves, and when the clothes hanger (590) mounted on the hanging part (570) shakes, an effect of the clothes being fluttered may be produced.

[0123] The power transmission unit (530) may be provided in multiple units, and the hanging unit (570) coupled to the power transmission unit (530) may also be provided in multiple units. As a result, a large number of clothes corresponding to the number of power transmission units (530) can be placed inside the inner case (200) and refreshed.

[0124] The above moving hanger (500) may further include a driving unit (510) that provides power to move the power transmission unit (530).

[0125] The above driving unit (510) may be provided so as to be exposed inside the inner case (020) if it can transmit power to the power transmission unit (530). However, since the driving unit (510) is provided so as to operate by receiving electric energy, it is preferable that exposure to steam or hot air be blocked.

[0126] Accordingly, the driving unit (510) can be placed between the upper surface of the inner case (200) and the cabinet (100) to prevent it from being exposed to the receiving space (210).

[0127] The power transmission unit (530) can receive power from the driving unit (510) by penetrating the inner case (200) and transmit it to the hanging unit (570).

[0128] The power transmission unit (530) may penetrate the upper surface of the inner case (200) and extend into the receiving space (210). The lower end of the power transmission unit (530) may be exposed to the receiving space (210), and the upper end of the power transmission unit (530) may be exposed above the inner case (200).

[0129] The inner case (200) or the support member (580) may further include a sealing member capable of sealing an area penetrated by the power transmission member (530). The sealing member may include a support bearing or the like that is coupled to a hole in the inner case (200) and the support member (580) that allows the power transmission member (530) to penetrate therethrough and rotatably supports the power transmission member (530).

[0130] As a result, the air and steam supplied to the inner case (200) can be prevented from leaking above the upper surface of the inner case (200) or above the support member (580). As a result, the driving unit (510) that is positioned above the support member (5800) can be stably driven without problems such as leakage, short circuit, or overheating.

[0131] The above power transmission unit (530) may be provided in a rod shape, a tube shape, or a plate shape, etc., in which the length is longer than the thickness.

[0132] Meanwhile, the upper surface of the inner case (200) can support the load of the power transmission unit (530) and the driving unit (510). Clothes are placed and moved on the power transmission unit (530), and the load of the driving unit (510) is also relatively heavy. Therefore, in order to stably install the moving hanger (100) on the upper surface of the inner case (20), the clothing treatment device (1) of the present invention may further include a support unit (580).

[0133] The above support member (580) is placed on the upper portion of the inner case (20), and can be supported by being coupled to the cabinet (1). The above support member (580) can be made of a durable and non-deformable metal material.

[0134] The power transmission unit (530) and the driving unit (510) may be mounted on the support unit (580) and placed on the upper portion of the inner case (200). The power transmission unit (530) may extend through the support unit (580) into the receiving space (210).

[0135] Meanwhile, the driving unit (510) includes a motor that rotates the rotation shaft. The driving unit (510) may be provided to move the power transmission unit (530) with the power that rotates the rotation shaft.

[0136] However, it may be difficult to sufficiently shake the power transmission unit (530) by simply rotating the rotation shaft in place. Therefore, the moving hanger (500) may further include a displacement generating unit (520) that is coupled to the rotation shaft rotated by the motor and generates sufficient displacement to allow the power transmission unit (530) to move.

[0137] The displacement generating unit (520) may be connected or coupled to the driving unit (510).

[0138] For example, the displacement generating unit (520) may be provided to transmit the power of the driving unit (510) to the power transmission unit (530).

[0139] The displacement generating unit (520) may include an eccentric shaft that rotates along a trajectory larger than the diameter of the rotational axis. The eccentric shaft may be directly coupled to the rotational axis of the driving unit (510), but may be eccentrically coupled to or extended from a power shaft or the like that rotates by the rotational axis.

[0140] The displacement generating unit (520) may be configured in any manner as long as it can generate displacement that causes the power transmission unit (530) to move back and forth within a certain range. The detailed structure will be described later.

[0141] When the above driving unit (510) operates, the power generated from the rotation shaft generates displacement of the displacement generating unit (520), and the power transmission unit (530) can move according to the displacement of the displacement generating unit (520).

[0142] The displacement generating unit (520) can directly move the power transmission unit (530), but can also move the power transmission unit (530) through additional configuration.

[0143] The moving hanger (500) of the present invention can be equipped to reciprocate the power transmission unit (530).

[0144] In addition, the moving hanger (500) of the present invention may be equipped to rotate the power transmission unit (530). Specifically, the moving hanger (500) may be equipped to rotate the power transmission unit (530) reciprocally within a certain angular range, rather than moving the power transmission unit (530) reciprocally in a straight line.

[0145] The power transmission unit (530) may be provided to reciprocate clockwise or counterclockwise from a fixed position, and clothing placed on the power transmission unit (530) may also rotate clockwise or counterclockwise. The power transmission unit (530) is provided to rotate by the moving hanger (500), but its position may be variable, such as to the left or right, and may not move.

[0146] Even if the clothing rotates due to the power transmission unit (530) inside the inner case (200), the movement of the center of gravity inside the inner case (200) can be limited. Accordingly, even if the moving hanger (500) operates, the vibration generated inside the inner case (200) can be drastically reduced, and noise generation can also be minimized.

[0147] To this end, the moving hanger (500) may further include a reciprocating rotation unit (540) that converts continuous rotational energy generated from the driving unit (510) or the displacement generating unit (520) into a reciprocating rotational motion of the power transmission unit (530).

[0148] The reciprocating rotation part (540) may be provided to connect the displacement generating part (520) and the power transmitting part (530) to each other. The reciprocating rotation part (540) may be provided to connect the displacement generating part (520) and the power transmitting part (530) to each other at a position above the inner case (20). The reciprocating rotation part (540) may be prevented from being exposed to the receiving space (21), thereby preventing the clothing from being damaged by the reciprocating rotation part (540).

[0149] Meanwhile, the moving hanger (100) may be provided to reciprocate only one of the plurality of power transmission units (530).

[0150] However, if only one power transmission unit (530) rotates, clothing placed on the rotating power transmission unit may collide with clothing placed on another power transmission unit (530) and be damaged. In addition, there is a risk that the impact may be transmitted to the moving hanger (100), causing damage to the moving hanger (100).

[0151] Therefore, it is preferable that the moving hanger (100) be equipped to rotate all of the plurality of power transmission units (530).

[0152] The above moving hanger (100) can rotate multiple power transmission units (530) as one unit. The above moving hanger (400) can be equipped to simultaneously rotate multiple power transmission units (530) at the same angle. Accordingly, the garment treatment device of the present invention can prevent the power transmission units (530) from colliding with each other.

[0153] The power generated in the above driving unit (510) may be directly transmitted to multiple power transmission units (530), which may be advantageous in rotating all of the power transmission units (530).

[0154] However, if the driving unit (510) is provided to directly transmit power to each power transmission unit (530), the structure connecting the driving unit (510) and all power transmission units (530) may become complicated.

[0155] In addition, if the driving unit (510) is provided in multiple units or if the components connecting all power transmission units (530) in the driving unit (510) are provided in multiple units, excessive load may be applied to the inner case (200) or the support unit (580). In addition, the inconvenience of having to control multiple driving units (510) may also arise.

[0156] In addition, if the power transmitted from one driving unit (510) is connected so that the displacement generating unit (520) and the reciprocating rotating unit (540) are each transmitted to all power transmission units (530), the arrangement and structure of the displacement generating unit (520) and the reciprocating rotating unit (540) may become complicated, which may lower reliability.

[0157] Therefore, the moving hanger (100) may be provided so that one driving unit (510) generates power to rotate a plurality of power transmission units (530).

[0158] In addition, the moving hanger (100) may be provided so that the power generated in the driving unit (510) is preferentially transmitted to some of the power transmission units (530) or some of the reciprocating rotation units (540), and the remaining power transmission units (530) or the remaining reciprocating rotation units (540) can secondarily receive the power.

[0159] For example, the reciprocating rotation unit (540) may be provided to receive power transmitted from the driving unit (510) or the displacement generating unit (520) and transmit it to some of the power transmission units (530). That is, the moving hanger (100) is provided to intensively transmit the power generated from the driving unit (510) to one reciprocating rotation unit (540), so that the power transmission structure can be designed simply and power loss can be minimized.

[0160] The moving hanger (100) of the present invention may be provided so as to transmit power transmitted from the driving unit (510) to one reciprocating rotating unit (540), thereby rotating a specific power transmission unit (530) connected to the reciprocating rotating unit (540).

[0161] In addition, the moving hanger (100) may further include a connecting portion (560) that is provided to transmit power transmitted to a specific power transmission portion (530) to another power transmission portion (530).

[0162] For example, the connecting portion (560) may be provided to connect a plurality of power transmission portions (530) to each other. Thus, when one power transmission portion (530) rotates, the connecting portion (560) can rotate all of the plurality of power transmission portions (530).

[0163] Figure 3 illustrates how the moving hanger of the present invention operates.

[0164] Referring to Fig. 3(a), the power transmission unit (530) can rotate to the right by the reciprocating rotation unit (540) when the driving unit (510) operates. At this time, the power transmission units (530) connected to the connecting unit (560) can also rotate to the right.

[0165] Referring to Fig. 3(b), the power transmission unit (530) can rotate to the left by the reciprocating rotation unit (540) when the driving unit (510) is further operated. At this time, the power transmission units (530) connected to the connecting unit (560) can also rotate to the left.

[0166] As this process is repeated, the power transmission unit (530) can rotate left and right.

[0167] At this time, the power transmission unit (530) may be provided to rotate left and right while being fixed in a fixed position. The power transmission unit (530) may be fixed to the support unit (580) so that there is no change in position in the forward, backward, left and right directions when rotating.

[0168] The above power transmission unit (530) can be fixed so that its position does not move in the up-down direction, front-back direction, and width direction.

[0169] However, the power transmission unit (530) may be provided to rotate left and right with the vertical or height direction in which the power transmission unit extends as the rotation axis. As a result, when the driving unit (510) is driven, the hook unit (570) may reciprocate left and right with the power transmission unit (530) as the axis, and there may be no positional movement.

[0170] Referring to Fig. 3(c), when the power transmission unit (530) rotates to the left, the left side of the hanger (590) can rotate to the left and the right side can rotate to the right. At this time, the angle (I) at which the left side rotates is the same as the angle (theta) at which the right side rotates, and the distance at which the left side moves can be the same as the distance at which the right side moves. As a result, the weight and force moving to the left with respect to the hanger (590) are the same as the weight and force moving to the right, and thus can cancel each other out.

[0171] Likewise, even if the power transmission unit (530) rotates to the right, as a result, the weight and force moving to the left with respect to the hanger (590) are equal to the weight and force moving to the right, and thus can be offset from each other.

[0172] Figure 4 illustrates the structure of the machine room of the garment treatment device of the present invention.

[0173] The inside of the above machine room (300) may include a refresh module (T) configured to supply hot air and steam to clothes placed in the receiving space (210), circulate air inside the receiving space, or circulate air outside the cabinet, and an ironing module (S) including the steam iron (1300).

[0174] The above refresh module (T) may include all devices and configurations that can supply at least one of hot air and steam to the inside of the inner case (200).

[0175] Specifically, the refresh module (T) may include a base part (310) that supports the various devices described above or provides a space for installation, a circulation duct (320) that is installed or extended from the base part (310) and provides a path for air inside the inner case (200) or air outside the cabinet (200) to move, a blower part (350) that is mounted on the circulation duct (320) and provides power to move the air, a heat supply part (340) that cools and heats the air moving along the circulation duct (320) to generate hot air, and a steam supply part (800) that is supported on the base part (310) or mounted on the circulation duct (320) and supplies steam to the inside of the inner case (200).

[0176] The above base part (310) may be provided as a plate on which various devices are installed.

[0177] The above circulation duct (320) forms a path through which air flowing in from outside the inner case (200) or the cabinet (100) moves, and may be provided in the shape of a case with an open upper surface.

[0178] The heat supply unit (340) may include a heat exchanger that is arranged inside the circulation duct (320) to cool the air, condense moisture, and reheat the air, and a compressor that is arranged outside the circulation duct (320) to receive refrigerant from the heat exchanger or supply refrigerant.

[0179] The above refresh module may further include an outside air duct (370) that draws in outside air in front of the circulation duct (320) and guides it into the inside of the circulation duct (320).

[0180] The above circulation duct (320) is provided to communicate with the outside air duct (370) and can be provided to selectively suck in outside air.

[0181] The above water supply tank and the above drain tank may also be included in the above refresh module (T).

[0182] The water supply tank and drain tank can be detachably connected to the front of the above circulation duct (320). For example, the water supply tank (301) and drain tank (302) can be installed and arranged on the upper part of the outside air duct (370).

[0183] The above circulation duct (320) may be provided by being coupled to the base portion (310), but may also be provided as an integral part with the base portion (310). For example, the base portion (310) and the circulation duct (320) may be manufactured simultaneously through injection molding.

[0184] The above refresh module (T) may include a base cover (360) provided to connect the circulation duct (320) and the inlet hole (232).

[0185] The above base cover (360) may be coupled to the upper portion of the circulation duct (320) to guide air sucked in from the inlet hole (232) into the interior of the circulation duct (320).

[0186] The above base cover (360) can block the upper surface of the circulation duct (320) to prevent air inside the circulation duct (320) from being discharged to the outside. The lower portion of the base cover (360) and the upper surface of the circulation duct (320) can form one side of the flow path of the circulation duct (320).

[0187] The above base cover (360) may include an inlet portion (362) that connects the inlet hole (232) and the circulation duct (320) therein. The inlet portion (362) is provided in a duct shape and may function as an intake duct that delivers air inside the inner case (200) to the circulation duct (320).

[0188] The steam supply unit (800) can be connected to the water tank (301) to receive water and generate steam. The steam supply unit (800) can be installed and positioned on the upper portion of the circulation duct (320). The steam supply unit (800) can be positioned at the rear of the base cover (360).

[0189] The above refresh module (T) may further include a steam nozzle (900) that receives steam from the steam supply unit (800) and supplies it to the inside of the inner case (200). The steam nozzle (900) may be placed between the steam supply unit (800) and the steam hole (233).

[0190] The water that is condensed and cannot be discharged from the steam nozzle (900) to the steam hole (233) can be recovered back to the steam supply unit (800).

[0191] The above blower (350) may be provided to communicate with the circulation duct (320) and the discharge hole (231).

[0192] The iron module (S) may be placed on the left or right side of the refresh module (T) inside the machine room (300). Specifically, the iron module (S) may be placed outside the circulation duct (320). As a result, the iron module (S) may not obstruct the air flow flowing through the circulation duct (320).

[0193] The above ironing module (S) can be arranged parallel to the length direction of the circulation duct (320) on one side of the base part (310).

[0194] Figure 5 illustrates the rear of the machine room.

[0195] The above blower (350) may include a blower fan (353) that provides power for the air inside the circulation duct (320) to move in one direction, and a fan housing (351) that accommodates the blower fan (353) and is coupled to or extended from the circulation duct (320).

[0196] The above blower (350) may be equipped with an exhaust duct (352) that is provided to communicate the circulation duct (320) and the exhaust hole (232).

[0197] The above exhaust duct (352) may be provided so as to extend toward the exhaust hole (232) in the fan housing (351) with a cross-section corresponding to the area of ​​the exhaust hole (232).

[0198] As a result, the air inside the inner case (200) can be introduced through the base cover (360), pass through the circulation duct (320), and then be supplied back into the inner case (200) through the fan installation part.

[0199] The heat supply unit (340) may include a compressor (343) installed in the base unit (310) and exchanging heat with air flowing through the circulation duct (320). The compressor (343) may be placed on the left or right side of the circulation duct (320), and may be placed between the circulation duct (320) and the iron module (S).

[0200] Figure 6 illustrates the circulation duct and base structure in the machine room of the garment treatment device of the present invention.

[0201] The above base portion (310) can form the lower surface of the clothing treatment device.

[0202] The above base portion (310) may include a base bottom portion (311) forming a support surface. The base bottom portion (311) may form the lower surface of the garment treatment device.

[0203] Of course, the base bottom part (311) can be installed on the upper surface of the bottom surface of a cabinet (100) separately provided to form the lower surface of the clothing treatment device.

[0204] The above base portion (310) may be integrally provided with the circulation duct (320) that forms at least a portion of the path through which air moves. The circulation duct (320) may be formed by extending upward from the base bottom portion (311).

[0205] The above circulation duct (320) may include a duct body (321) that extends from the base bottom part (311) to form a flow path, a heat exchanger installation part (3212) that provides a space in which an evaporator (341) or a condenser (342) is installed inside the duct body (321), and an air discharge part (323) that is provided at the rear of the duct body (321) and discharges air of the duct body (321) to a blower part (350).

[0206] The above air discharge unit (323) may be provided in the shape of a pipe extending rearward from the duct body (321). The diameter of the air discharge unit (323) may be provided to be smaller than the width of the duct body (321).

[0207] The above air discharge unit (323) can be connected to the above blower unit (350). Air discharged from the air discharge unit (323) can be guided into the inner case (200) through the blower unit (350).

[0208] The above circulation duct (320) may further include an outside air intake portion (322) formed by penetrating the front of the duct body (321). The outside air intake portion (322) may be provided to communicate with the outside air duct (370). The outside air duct (370) may be supported by being installed in front of the outside air intake portion (322).

[0209] The above circulation duct (320) may be equipped with a damper that opens and closes the outside air intake section (322). Opening and closing the damper allows or blocks outside air from flowing into the inside of the circulation duct (320).

[0210] The above base part (310) may include a compressor installation part (312) that provides a space in which the compressor (343) is installed. The compressor installation part (312) may be formed on one side of the base bottom part (311) and may be formed integrally with the base bottom part (311).

[0211] The compressor installation part (312) may be formed with a protrusion capable of supporting the compressor (343). The compressor installation part (312) may be positioned to be offset to the rear of the base part (310). The compressor installation part (312) may be positioned so that at least a portion thereof overlaps the air discharge part (323) in the width direction.

[0212] The above compressor installation part (312) may be equipped with a buffer member that reduces vibration transmitted from the compressor (343). The buffer member may be fixed to the protrusion.

[0213] The above base part (310) may be equipped with a compressor installation part (313) in which the compressor (343) that supplies refrigerant to the heat exchanger (341, 343) is installed. The compressor installation part (313) may be placed outside the circulation duct (320).

[0214] The above iron module (S) may be mounted on one side of the compressor installation part (312) or the base part (310). The iron module (S) may also be mounted on the base part (310). For example, the base bottom part (311) may extend from the circulation duct (320) to the corners of both sides of the machine room (300), and the iron module (S) may be mounted on the upper part of the base bottom part (311).

[0215] In addition, the iron module (S) may be installed in the machine room (300) by being placed outside the base floor portion (311). That is, the base floor portion (311) may have a smaller area than the floor surface of the machine room (300), and the iron module (S) may form the remaining floor surface of the machine room (300).

[0216] Figure 7 illustrates the inside of the circulation duct of the clothing treatment device of the present invention.

[0217] The above circulation duct (320) can extend upward from the base floor to form a flow path through which air flows.

[0218] The heat supply unit (340) may include an evaporator (341) that cools and condenses air moving along the circulation duct (320), a compressor (343) that receives refrigerant from the evaporator (341) and compresses and heats it, and a condenser (342) that receives refrigerant from the compressor (343) and heats the air moving along the circulation duct (320).

[0219] The above heat supply unit (340) may further include an expansion valve that expands the refrigerant that has passed through the condenser (342) to lower the temperature of the refrigerant.

[0220] The heat supply unit (340) may include an evaporator (341) installed inside the circulation duct (320) and equipped with a heat exchanger that cools and dehumidifies air introduced into the circulation duct (320), a condenser (342) equipped with a heat exchanger that heats air that has passed through the evaporator (341) to form hot air, a compressor (343) that supplies refrigerant that exchanges heat with the air to the condenser (342) and is arranged outside the circulation duct (320), and an expansion valve (344) that expands and cools the refrigerant that has passed through the condenser (342).

[0221] The above evaporator (341) and condenser (342) are placed inside the circulation duct (320), and the compressor (343) can be placed outside the circulation duct (320).

[0222] The above circulation duct (320) may include a heat exchanger installation part (3212) that provides a space in which an evaporator (341) and a condenser (342) are installed. The heat exchanger installation part (3212) may be provided inside the duct body (321).

[0223] The above duct body (321) may be provided with an open upper surface. A condenser (342) and an evaporator (341) may be installed by inserting them through the opening of the duct body (321).

[0224] The opening of the above duct body (321) can be shielded by the base cover (360), and the base cover (360) and the duct body (321) can form a path through which air moves inside the circulation path (320).

[0225] The front surface of the above duct body (321) can be arranged rearwardly from the front end of the base bottom portion (311). As a result, the base bottom portion (311) can secure a support surface (3111) on which one or more of the above-described water supply tank (30) or drain tank (40) and outdoor air duct (370) are installed and supported.

[0226] Meanwhile, as the duct body (321) is integrally formed with the base portion (310), the height of the heat exchanger installation portion (3212) can be secured longer, and the heights of the condenser (342) and the evaporator (341) can also be increased accordingly.

[0227] As a result, the width of the condenser (342) and the evaporator (341) in the front-rear direction can be reduced, thereby reducing the number of refrigerant pipes passing through the condenser and the evaporator. In addition, the effect of reducing the flow loss of air passing through the condenser and the evaporator is achieved.

[0228] Meanwhile, the sum of the length of the evaporator (341) and the length of the condenser (342) may be provided to be smaller than the length of the heat exchanger installation part (3212). Accordingly, the front-rear length of the heat exchanger installation part (3212) may be provided to be equal to or smaller than half of the length of the duct body (321).

[0229] The above blower (350) may be arranged to overlap the condenser (342) or the evaporator (341) in the front-rear direction. Accordingly, the air that has passed through the evaporator (341) and the condenser (342) can be introduced into the blower (350) without bending the flow path. That is, the air introduced into the circulation duct (320) can minimize flow loss because the flow path is not bent during the process of moving to the blower (350).

[0230] The length of the above ironing module (S) may be provided to be longer than the length of the above circulation duct (320).

[0231] Figure 8 illustrates a water supply and drainage system of the clothing treatment device of the present invention.

[0232] The clothing treatment device of the present invention may include a water supply tank (301) that supplies water to the steam supply unit (800) and a drain tank (302) that collects water condensed in the circulation duct (320) or ironing module (S).

[0233] The above water supply tank (301) and the above drain tank (302) should be selectively separated from the machine room (300) so that a user can easily fill the water supply tank (301) with water and discard the water collected in the drain tank (302).

[0234] The above machine room (300) may further include a detachable part (380) that is positioned in front of the refresh module (T) and supports the water supply tank (301) and the drain tank (302). The detachable part (380) may be detachably coupled to the water supply tank (301) and the drain tank (302).

[0235] The above detachable part (380) is provided in a plate shape to prevent the inside of the machine room (300) from being exposed.

[0236] A drainage pump (330) or the like may be provided at the lower portion of the detachable portion (380), and a circulation duct (320) may be provided at the rear of the detachable portion (380).

[0237] The above ironing module (S) may be provided so that a part thereof penetrates the detachable portion (380).

[0238] The above ironing module (S) may be placed on one side of either the water supply tank (301) or the drain tank (302). The ironing module (S) may not be placed between the water supply tank (301) and the drain tank (302). As a result, the front-rear length of the ironing module (S) can be sufficiently secured.

[0239] The above ironing module (S) can be arranged closer to the water supply tank (301) than to the drain tank (302). As a result, water can be easily supplied from the water supply tank (301), heated, and delivered to the steam iron (1300), and the structure for supplying water from the water supply tank (301) can be simply designed, and the volume occupied by the structure can also be minimized.

[0240] Figure 9 illustrates the installation structure of a steam supply unit that receives water from a water tank.

[0241] The above steam supply unit (800) can be supported by being installed on the base cover (360).

[0242] The above base cover (360) may include an inlet body (361) that is coupled to the upper surface of the circulation duct (320) to connect the inner case (200) and the circulation duct (320), and a shielding body (363) that extends from the inlet body (361) to shield the upper surface of the circulation duct (320).

[0243] The above inlet body (361) may be provided in a duct shape to communicate between the inlet hole (231) of the inner case and the inside of the circulation duct (320). The inlet body (361) may be provided to protrude further upward than the shielding body (363).

[0244] The above inlet body (361) may be placed in front of the evaporator (341) so as not to face the evaporator (341) and the condenser (342).

[0245] The above inlet body (361) can serve as an inlet duct that moves air from the inner case (200) to the circulation duct (320). The inlet body (361) can be provided with an inlet portion (362) therein through which air from the inner case (200) can pass.

[0246] The above inlet (362) may be provided in multiple sections, and a filter may be inserted and installed in one of the sections.

[0247] The above shielding body (363) may include a shielding panel (3631) that blocks the evaporator (341) and the condenser (342) from being exposed to the outside and supports the steam supply unit (800), a power terminal (3632) that extends from the shielding panel (3631) or the inlet body (361) to supply power to the steam supply unit (800), and a protection panel (3632) that accommodates and protects one of both sides of the steam supply unit (800).

[0248] The outer surface of the above protective panel (3632) may be provided with a plurality of reinforcing ribs to enhance rigidity. This prevents vibrations or shocks generated in the inner case (200) or machine room (300) from being transmitted to the steam supply unit (800).

[0249] The above steam supply unit (800) can be supported by being mounted on the base cover (360).

[0250] The above steam supply unit (800) may include a steam case (810) that stores water that generates the steam.

[0251] The compressor (343) may be placed below the steam supply unit (800).

[0252] Meanwhile, the base cover (360) may include a fastening portion (3631) that is provided on the shielding body (363) and detachably coupled to the steam supply unit (800). The fastening portion (3631) may be provided with a structure that detachably couples with a protrusion protruding from the lower portion of the steam case (810).

[0253] Accordingly, even if a large amount of water is contained inside the steam supply unit (800), the steam supply unit (800) can be stably installed on the base cover (360).

[0254] In addition, since the steam supply unit (800) is positioned above the circulation duct (320) and the distance from the inner case (200) becomes shorter, it is possible to minimize condensation of the steam generated in the steam supply unit (800) before it reaches the inner case (200).

[0255] Figure 10 illustrates the appearance of the steam supply unit.

[0256] The above steam supply unit (800) may include a steam case (810) that can receive and store water to generate steam, and a heater unit (840) that is accommodated in the steam case (810) and heats the water to generate steam.

[0257] The above steam case (810) may be provided in the form of a case with an open upper portion, and may be provided to accommodate the heater unit (840).

[0258] The steam supply unit (800) may further include a case cover (820) that is coupled to the steam case (810) to prevent the heater unit (840) from being exposed to the outside and to prevent the water from leaking out.

[0259] The case cover (820) may be equipped with a water level sensor (850) that detects the water level of the steam case (810) and a steam sensor (860) that detects the temperature inside the steam case (810) or whether steam is generated inside the steam case (810).

[0260] Figure 11 illustrates the internal structure of the steam supply unit.

[0261] The above steam case (810) may include a case body (811) that provides a space for storing the water and accommodating a heater unit (840).

[0262] The above case body (811) may be provided in a shape with an open upper portion. Accordingly, various components can be easily installed inside the case body (811).

[0263] The above case body (811) may include a heater insertion hole (815) through which the heater (840) can be inserted or withdrawn through one side.

[0264] The above case body (811) may include a residual water pipe (813) that can discharge water contained therein to the outside. The residual water pipe (813) may be kept closed by a residual water stopper so that it is opened only when removing residual water inside the steam case (810).

[0265] Meanwhile, a heater fixing part (812) that can support or fix the heater part (840) can be installed inside the case body (811).

[0266] Meanwhile, the steam supply unit (800) may be equipped with a recovery pipe (824) for receiving water. The recovery pipe (824) is provided to be connected to the water supply tank (301) to receive water, and may be connected to the water supply tank (301) through the steam nozzle (900).

[0267] The above recovery pipe (824) may be provided in the case cover (820). As a result, water can be stored entirely in the steam case (800), and water can be prevented from flowing back through the recovery pipe (824).

[0268] The steam supply unit (800) may be equipped with a steam pipe (823) that discharges steam generated by the operation of the heater unit (840) to the outside. The steam pipe (823) may also be installed on the upper portion of the case cover (820) to block water from being discharged into the steam pipe (823). The steam pipe (823) may be connected to the steam nozzle (900).

[0269] The water level sensor (850) may include a sensor body (851) having one or more contact protrusions that are inserted into the water level sensor hole (854) and immersed in water to detect the water level, and a fixing member (852) that fixes the sensor body (851) to the case cover (820).

[0270] The steam sensor (860) may include a sensing unit (861) that senses a change in temperature or pressure inside the steam case (810), a support plate (862) that supports the sensing unit (861), and a fastening member (862) that secures the support plate (862) to the case cover (820).

[0271] Meanwhile, the steam supply unit (800) may further include a fixing plate (871) that is coupled to the case cover (820) to fix the heater unit (840), and a coupling member (872) that fixes the fixing plate (871) to the case cover (820).

[0272] The above case cover (820) may further include a cover hook (821) that extends forward and can be coupled to the base cover (360).

[0273] The above heater unit (840) may be inserted into the heater insertion hole (815) and accommodated in the steam case (810) and may be equipped to receive power and heat water.

[0274] The above heater unit (840) may be equipped with a sis heater, etc., and may be controlled by the control unit so that driving and stopping can be repeated.

[0275] The heater unit (840) may include a first heater (841) that receives a first electric power to heat water, and a second heater (842) that receives a smaller electric power to heat water. Consequently, the first heater (841) may be configured to heat a larger amount of water than the second heater (842) to generate more steam.

[0276] The first heater (841) and the second heater (842) may be provided to divide and consume the maximum heater power allowed for the heater unit (840) in the clothing treatment device. That is, if the first heater (841) is provided to consume a portion of the maximum heater power, the second heater (842) may be provided to consume the remainder of the maximum heater power.

[0277] For example, if the general maximum heater power that can be allowed for the heater unit (840) is 1500W, the second heater (842) may be equipped to consume 600W, and the first heater (841) may be equipped to consume 880W. 20W may be distributed less in consideration of errors, etc.

[0278] Of course, the heater unit (840) may include three or more heaters. For example, it may include the first heater (841), the second heater (842), and the third heater (843), and the first heater (841), the second heater (842), and the third heater (843) may be provided to divide and consume the maximum heater power.

[0279] Hereinafter, the heater unit (840) is described based on the first heater (841) and the second heater (842).

[0280] The above first heater (841) and the above second heater (842) can be formed as a U-shaped metal tube.

[0281] The above heater unit (840) may further include a heater sealer (843) that can fix the first heater (841) and the second heater (842) and seal the heater penetration hole (8111).

[0282] The first heater (841) and the second heater (842) may be arranged at the same height. Accordingly, the first heater (841) and the second heater (842) may be provided to heat water at the same water level to generate steam.

[0283] Accordingly, the control unit can selectively use the first heater (841) and the second heater (842) to control the amount of steam generated and the amount of power consumed.

[0284] Figure 12 illustrates a control method for performing a course for processing clothes by the garment processing device of the present invention.

[0285] The garment treatment device of the present invention can perform any course of treating garments.

[0286] The above arbitrary course may include performing a refreshing process of deodorizing, removing wrinkles, and drying the clothing by supplying at least one of heated air (hot air) and steam to the clothing, and may drive a moving hanger (500) during this process.

[0287] The clothing treatment device of the present invention can perform a steam preparation step (B1) of driving the heater unit (840) to supply steam to the clothing when any course capable of refreshing or managing the clothing is performed.

[0288] The above steam preparation step (B1) can reduce the refresh cycle time as the steam is generated more quickly, so all heaters of the heater unit (840) can be driven.

[0289] In other words, in the steam preparation step (B1), water can be heated using the maximum power of the heater unit (840).

[0290] For example, if the heater unit (840) is composed of the first heater (841) and the second heater (842), the first heater (841) and the second heater (842) can be driven simultaneously to heat water.

[0291] When the detection device (860) detects that steam is generated inside the steam case (810) in the above steam preparation step (B1), the clothing treatment device of the present invention can perform a preheating step (B2) of driving only one of the first heater (841) and the second heater (842).

[0292] After steam is generated in the steam case (810), the steam can be continuously supplied to the inner case (200) by using only one of the first heater (841) and the second heater (842).

[0293] Accordingly, in the preheating step (B2), steam can be supplied to the inner case (200) using only one of the first heater (841) and the second heater (842) to increase the temperature inside the inner case (200) and increase the moisture content of the clothing, and an extra amount of power that can be used for the compressor (343) can also be secured.

[0294] The first heater (841), the second heater (842), and the compressor (343) cannot be driven simultaneously due to limitations in the allowable power, but even if either one of the first heater (841) and the second heater (842) and the compressor (343) is driven simultaneously, the power may be lower than the allowable power. As a result, in the preheating step (B2), the garment treatment device of the present invention can supply hot air to the inner case (200) by driving the compressor (343) simultaneously.

[0295] In the above preheating step (B2), either the first heater (841) or the second heater (842) and the compressor (343) can be driven simultaneously. As a result, steam and hot air can be supplied simultaneously to the inner case (200). Therefore, the temperature inside the inner case (200) can be increased from the beginning of the refresh cycle, and the heat exchange performance of the evaporator (341) can be enhanced, thereby improving the coefficient of performance (cop) of the heat supply unit (340).

[0296] In addition, the clothing can reach the optimal temperature or minimum temperature required for refreshing from the preheating step (B2), thereby significantly reducing the time for the subsequent drying step.

[0297] The above preheating step (B2) may include a section in which either the first heater (841) or the second heater (842) and the compressor (343) are driven simultaneously, and a section in which only the compressor (343) is driven.

[0298] In the above preheating step (B2), there may be a section in which only the compressor (343) is driven, rather than a section in which only the heater unit (840) and the compressor (343) are driven simultaneously.

[0299] However, it is preferable that the section in which only the compressor (343) is driven be placed after the section in which the heater section (840) and the compressor (343) are driven. When the steam is supplied to the inner case (200) through the heater section (840), not only does the temperature inside the inner case (200) rise, but also the increased temperature of the evaporator (341) and moisture come into contact with it, allowing a large amount of heat exchange to be performed with the refrigerant passing through the evaporator (341). Therefore, the performance of the heat supply section (340) is improved, allowing the temperature inside the inner case (200) to rise quickly.

[0300] For example, the preheating step (B2) may include a first section in which either the first heater (841) or the second heater (842) and the compressor (343) are driven, and a second section in which the operation of the first heater (841) or the second heater (842) is stopped and only the compressor (343) is driven.

[0301] By supplying hot air and steam to the inner case (200) through the first section above, the temperature inside the inner case (200) and the heat amount of the air flowing into the circulation duct (320) can be increased.

[0302] Through the second section, hot air is supplied to the inside of the inner case (200) to satisfy the minimum temperature conditions for refreshing clothes through deodorization, wrinkle removal, and sterilization.

[0303] In the above preheating section (B2), the second heater (842) can be driven more than the first heater (841). As a result, a larger amount of steam can be supplied to the inner case (200) than when the first heater (841) is driven, thereby further increasing the temperature inside the inner case (200) and the amount of heat of the air flowing into the circulation duct (320).

[0304] Of course, in the preheating section (B2), the first heater (841) may be driven and the second heater (842) may not be driven. Accordingly, in the preheating section (B2), although the temperature rise of the inner case (200) is not large, a small amount of steam can be sprayed to prevent clothing from being damaged by moisture. In addition, even if steam is sprayed for a longer period of time, the temperature rise is not large, so more time can be secured for sterilization, etc.

[0305] The above preheating section (B2) may be completed when the temperature inside the inner case (200) reaches a reference temperature, the temperature of the air discharged from the inner case (200) reaches a reference temperature, or the temperature of the refrigerant discharged from the compressor (343) reaches a set temperature. To this end, the garment treatment device of the present invention may include a temperature sensor installed inside the inner case (200) or in the circulation duct (320) to detect the temperature of the air or the temperature of the refrigerant discharged from the compressor (343).

[0306] When the above preheating section (B2) is completed, the garment treatment device of the present invention can perform a steam injection step (B3) to supply steam in earnest into the inner case (200). In the steam injection step (B3), the first heater (841) and the second heater (842) can be operated simultaneously to supply a large amount of steam to the inner case (200). Accordingly, the garments placed in the inner case (200) can receive full-scale steam while being heated to a certain level in the preheating step (B2), thereby increasing the moisture content throughout the entire garment.

[0307] The above steam injection step (B3) can be performed for a shorter time than the existing steam injection step (A2). This is because a certain level of steam has already been supplied in the above preheating step (B2).

[0308] Once the above steam injection step (B3) is performed, a drying step (B6) for drying the clothing with hot air can be performed immediately. However, a waiting step (B4) can be performed first to wait for a certain period of time to ensure that the steam injected in the steam injection step (B3) has time to penetrate the entire clothing.

[0309] The above standby stage (B4) is a state in which the heater unit (840) and the compressor (343) are not operated. Through the standby stage (B4), it is possible to prevent the clothing from drying before being fully exposed to steam, and to prevent the clothing from being damaged by heat due to the supply of hot air immediately after the surface temperature of the clothing has risen due to the steam.

[0310] Meanwhile, the drying step (B6) is a step in which the compressor (343) is driven to supply hot air to the inner case (200). Therefore, if hot air is supplied immediately while the temperature inside the inner case (200) has not fallen below the safety temperature, the temperature inside the inner case (200) may rise above the limit temperature, causing damage to the clothing.

[0311] Therefore, a cooling step (B5) for driving the blower fan (352) may be performed before performing the drying step (B6). In the cooling step (B5), the blower fan (352) may be driven, and the compressor (343) and the heater unit (840) may be stopped from driving.

[0312] In the above cooling step (B5), the air inside the inner case (200) can be cooled by circulating along the circulation duct (200).

[0313] When the temperature inside the inner case (200) drops below a safe temperature or the cooling step (B5) is performed for a required period of time, the clothing treatment device of the present invention can perform a drying step (B6) of supplying hot air to the clothing.

[0314] The above drying step (B6) may be performed until the moisture content of the clothing falls below a certain level. For example, when the clothing contains a lot of moisture, the temperature flowing into the circulation duct (320) due to the heat of vaporization may be maintained or may not rise rapidly when the above drying step (B6) is performed.

[0315] However, if the clothes are mostly dry, the temperature flowing into the circulation duct (320) may rise rapidly because the heat of vaporization is low. In this way, when the dryness of the clothes is secured and the minimum time required for refreshing has elapsed, the operation of the compressor (343) may be stopped, thereby ending the drying step (B6).

[0316] In addition, the clothing treatment device of the present invention may end the drying step (B6) when the time for which the clothing is placed above the minimum temperature condition reaches a minimum time.

[0317] The clothing treatment device of the present invention can significantly reduce the duration of the drying step (B6) by further arranging a preheating step (B2) before the drying step (B6) to increase the total time for the temperature inside the inner case (200) to reach a temperature higher than the minimum condition temperature.

[0318] Meanwhile, the clothing treatment device of the present invention can maintain the state in which the compressor (343) is stopped from operating in the preheating section (B2) until the drying step (B6) is performed.

[0319] Meanwhile, the moving hanger (500) can be operated intensively in the drying step (B6). As a result, the clothing can be more smoothly exposed to hot air, moisture can be evaporated, and odors can be eliminated while drying.

[0320] The moving hanger (500) of the garment treatment device of the present invention may operate and stop at different stages, or may operate at different speeds, depending on the condition of the garment. This will be described later.

[0321] Figure 13 illustrates a structure for detecting the condition of clothing using a light sensor of the clothing treatment device of the present invention.

[0322] The garment treatment device of the present invention can provide a garment treatment device including a light emitting part (600) that emits light into the inner case (200) and a sensor part (700) that detects that at least a portion of the light emitted from the light emitting part (600) is blocked.

[0323] The sensor unit (700) is positioned to be spaced apart from the light-emitting unit (600), and may be positioned closer to the bottom surface than the upper surface of the inner surface of the inner case (200).

[0324] In addition, the light emitting part (600) may be placed closer to the bottom surface than the top surface of the inner surface of the inner case (200), and may be placed inside the circulation duct (320).

[0325] As a result, in normal cases, the sensor unit (700) can always receive the light irradiated from the light emitting unit (600). However, when the clothing falls, the fallen clothing may interfere with the sensor unit (700), thereby blocking or hindering the sensor unit (700) from receiving the light from the light emitting unit (600).

[0326] For example, the sensor unit (700) is positioned closer to the bottom surface of the inner case (200) than the hanger unit, the sensor unit (700) detects a first value when the clothing has not fallen, and the control unit (C) can determine that the clothing has fallen when the sensor unit (700) detects a value smaller than the first value.

[0327] Accordingly, the clothing treatment device of the present invention can determine the falling state of the clothing through the change in the brightness of the light emitting part (600) detected by the sensor part (700).

[0328] The above light emitting unit (600) may be configured to emit any light that the sensor unit (700) can detect. For example, the wavelength of light emitted from the light emitting unit (600) may be within the range of ultraviolet rays, visible light, etc.

[0329] The light source of the above light emitting unit (600) can be provided by any device that emits light, such as an LED or a light bulb.

[0330] The sensor unit (700) may be provided as an illuminance sensor that detects changes in the illuminance of light emitted from the light-emitting unit (600). Illuminance is a measure of brightness, and when a large amount of light is incident, the illuminance increases, and conversely, when a small amount of light is incident, the illuminance decreases.

[0331] The above sensor unit (700) can detect not only whether light emitted from the light emitting unit (600) is received, but also the intensity of the light.

[0332] At least one of the above light-emitting unit (600) and the above sensor unit (700) may be provided inside the clothing treatment device.

[0333] Figure 14 illustrates the structure of the inlet body of the circulation duct of the clothing treatment device of the present invention.

[0334] The above clothing treatment device may include a filter unit (380) at the upper part of the machine room (300) to prevent dust from entering the inside of the circulation duct (320).

[0335] The above filter unit (380) may be mounted on the inlet body (361) to filter dust flowing into the inlet body (361).

[0336] The above filter unit (380) may include at least one of a body filter (386) mounted on the base cover (360) or the upper portion of the inlet body (361) to shield a portion of the upper surface of the inlet body (361), a body cover (385) on which the body filter (386) is mounted, a filter fixing unit (384) for fixing the body cover (385) and the body filter (386), a filter cover (382), and a blocking cover (381) disposed on the upper portion of the filter cover (382). The blocking cover (381) may completely block the open upper surface of the machine room (300).

[0337] The above light emitting unit (600) may be positioned lower than the filter unit (380) and may be provided to irradiate light into the inside of the inlet body (361).

[0338] In this way, the exposure of the light emitting unit (600) to foreign substances or interference can be minimized. Furthermore, the light sensor (700) can detect whether the filter unit (380) is installed while detecting the light of the light emitting unit (600).

[0339] Meanwhile, the filter unit (380) may further include a reflector installed at the bottom so that the light irradiated from the light emitting unit (600) can be transmitted to the light sensor (700).

[0340] Figure 15 illustrates an embodiment of a reflective part of the clothing treatment device of the present invention.

[0341] In the clothing treatment device of the present invention, the light emitting part (600) is arranged at the lower part of the filter part (380), and the sensor part (700) is arranged at the upper part of the filter part (380).

[0342] The sensor unit (700) is positioned behind the filter unit (380) and can detect the state of the bottom surface of the filter unit (380) and the inner case (200).

[0343] The above filter unit (380) may include a reflector (400) that guides light irradiated from the light emitting unit (600) to the sensor unit (700).

[0344] The above reflective portion (400) may have a surface capable of reflecting light. For example, the above reflective portion (400) may be provided as a mirror.

[0345] The light irradiated from the above light emitting unit (600) can be reflected by the reflecting unit (400) along the direction of the arrow and guided to the sensor unit (700).

[0346] The above reflective part (400) may include a first reflective part (410) arranged on the upper side of the light-emitting part (600), and a second reflective part (420) and a third reflective part (430) arranged symmetrically on both sides of the first reflective part (410).

[0347] The second reflector (420) and the third reflector (430) may be provided on the lower surface of the filter cover (382) so as to be close to both corners of the filter cover (382).

[0348] Accordingly, the sensor unit (700) can receive the light irradiated from the first reflector (410) and the light irradiated from the second reflector (420) and the third reflector (430), respectively.

[0349] In this way, the same effect as having the same number of light-emitting parts (600) as the number of reflecting parts can be achieved. As a result, the sensor part (700) can detect not only the linear distance between the light-emitting part (600) and the sensor part (700), but also whether or not clothing has fallen within the area extending from the second reflecting part (420) and the third reflecting part (430) to the sensor part (700).

[0350] Figure 16 illustrates an embodiment of a reflective part of the clothing treatment device of the present invention.

[0351] The above reflective part (400) may be provided with only the second reflective part (420) and the third reflective part (430) by omitting the first reflective part (410).

[0352] Accordingly, the light irradiated from the light emitting portion (600) can be reflected by the second reflecting portion (420) and the third reflecting portion (430) and transmitted to the sensor portion (700).

[0353] As a result, the sensor unit (700) can detect all light irradiated in the area between the straight-line distance of the sensor unit (700) from the second reflector (420) and the third reflector (430).

[0354] Figure 17 illustrates an area that can be detected by the sensor unit (700).

[0355] The above sensor unit (700) can be placed at the rear of the inner case (200) and can be placed in the center portion based on the width of the bottom surface of the inner case (200).

[0356] The above sensor unit (700) may be placed further back than the discharge hole (232).

[0357] The above sensor unit (700) may be positioned behind the filter unit (380) and the inlet hole (231), and may be positioned at a height spaced upward from the bottom surface of the inner case (200).

[0358] The above sensor unit (700) may be placed closer to the bottom surface of the inner case (200) than the moving hanger (500).

[0359] The width of the above filter unit (380) may be provided to be longer than the width of the inlet hole (231).

[0360] The gap between one side of the filter unit (380) and one side of the inner case (200) can be set to be the same as the gap between the other side of the filter unit (380) and the other side of the inner case (200).

[0361] For example, the width of the filter unit (380) may be provided to be longer than half or 3 / 4 of the width of the bottom surface of the inner case (200).

[0362] In this state, the second reflector (420) can be placed on one side of the bottom surface of the filter unit (380), and the third reflector (430) can be placed on the other side of the bottom surface of the filter unit (380).

[0363] The above light emitting part (600) is placed inside the inlet body, and may be placed in the center area of ​​the width of the inner case (200). The light emitting part (600) may be placed parallel to the sensor part (700) in the front-back direction.

[0364] The light emitted from the above light emitting unit (600) can move directly to the sensor unit (700) in the forward and backward direction (I).

[0365] In addition, light irradiated from the light emitting portion (600) to one side of the inner case (200) can be reflected from the second reflecting portion (420) and guided from one side to the other direction (II) toward the sensor portion (700).

[0366] In addition, light irradiated from the light emitting portion (600) to the other side of the inner case (200) can be reflected from the third reflecting portion (430) and guided in a one-sided direction (III) toward the sensor portion (700) from one side.

[0367] As a result, the sensor unit (700) may be provided to receive light irradiated to the area between the filter unit (380) and the sensor unit (700). As a result, the area inside the arrow may correspond to a detection area that the sensor unit (700) can detect.

[0368] Figure 18 illustrates a situation in which the sensor part detects a falling part of clothing.

[0369] The above light emitting part (600) can emit light inside the inlet body (361).

[0370] The light irradiated from the above light emitting portion (600) can pass through the detection area formed on the bottom surface of the inner case (200) directly or through the reflection portion (400) and reach the sensor portion (700).

[0371] The above sensor unit (700) can set the illuminance that reaches the light irradiated from the light emitting unit (600) by passing only through the filter unit (380) to a normal value.

[0372] When clothing placed on the moving hanger (500) falls on the bottom surface of the inner case (200), at least a portion of the clothing may be placed in the detection area. At least a portion of the light irradiated from the light emitting unit (600) may be blocked by the clothing and may not reach the sensor unit (700). As a result, the sensor unit (700) may receive an illuminance value lower than the normal value and determine this as an abnormal illuminance, and the control unit of the clothing treatment device of the present invention may determine that the clothing has fallen.

[0373] Figure 19 illustrates a control method when detecting abnormal illuminance of the clothing treatment device of the present invention.

[0374] The clothing treatment device of the present invention can simultaneously perform the above-described abnormal illuminance detection step when any course for treating clothing is performed.

[0375] The above-mentioned abnormal illuminance detection step (A1) can be performed at any time before or during the clothing processing step after the power of the clothing processing device is turned on.

[0376] The above abnormal illuminance may include both cases where the illuminance value detected by the sensor unit (700) is greater than or less than the normal value.

[0377] For example, if the illuminance value is greater than the normal value, the filter unit (380) may not be installed, and if the illuminance value is less than the normal value or is 0, the clothing may have fallen from the moving hanger (500) into the detection area. Therefore, in the abnormal illuminance detection step (A1), the clothing treatment device can determine both whether the clothing has fallen and whether the filter unit (380) has been attached or detached by detecting whether the illuminance value detected by the sensor unit (700) is the abnormal illuminance.

[0378] Additionally, even when the sensor unit (700) is broken, the sensor unit (700) can detect abnormal illuminance.

[0379] If the above clothing is dropped, hot air or steam may not be supplied evenly to the entire surface of the clothing, so the clothing may not be refreshed, and the clothing may be damaged if the clothing comes into direct contact with the sprayed steam.

[0380] In addition, if the filter unit (380) is not installed, the light emitting unit (600) may be damaged or the circulation duct (320) or heat exchanger may be contaminated, which may cause problems in the performance of the clothing treatment device.

[0381] In addition, if a problem occurs in the sensor unit (700), a fundamental problem may occur in which the falling of clothing and the installation of the filter unit cannot be detected.

[0382] Accordingly, the clothing treatment device of the present invention can perform a stop step (A2) for stopping the execution of the course when abnormal illuminance is detected in the abnormal illuminance detection step (A1).

[0383] In this case, the clothing treatment device of the present invention can perform a notification step (A3) of displaying a state in which the clothing has fallen or a state in which the filter unit (380) is not installed on a display unit provided in the cabinet (100) or the door (40).

[0384] The garment treatment device of the present invention can display the reason for the course being interrupted in the notification step (A3). For example, the garment treatment device of the present invention can display the state in which the abnormal illuminance was detected or the state in which the abnormal illuminance was detected.

[0385] For example, the display unit of the clothing treatment device of the present invention can display information guiding the installation of the filter unit (380) when the illuminance value is an abnormal illuminance greater than the normal value, and can display information indicating that the clothing has fallen when the illuminance value is an abnormal illuminance less than the normal value.

[0386] Accordingly, the garment treatment device of the present invention can notify the user of a state in which the garment has fallen, the filter unit is not installed, or the sensor unit (700) cannot detect the illuminance or a change in the illuminance. As a result, the user can be guided to take appropriate action.

[0387] Conversely, if no abnormal illuminance is detected in the above-mentioned abnormal illuminance detection step (A1), the course progress step (A4) for performing the course normally can be performed.

[0388] The above course progress step (A4) may correspond to sequentially performing the control method for performing the aforementioned course.

[0389] Figure 20 illustrates a situation where long clothing is hung.

[0390] When the moving hanger (500) is operated while clothing is placed on the moving hanger (500), the clothing may shake inside the inner case (200).

[0391] At this time, as the length of the clothing increases, the width of the shaking of the ends of the clothing may increase, and when the driving speed of the moving hanger (500) increases, a wave pattern may be formed over the entire clothing and the clothing may vibrate.

[0392] At this time, the clothing may be a long garment having a length longer than 2 / 3 of the height of the inner case (200), or the end of the clothing may be placed in a position where it interferes with the light sensor (700) while the clothing is placed on the moving hanger (500).

[0393] Such long clothes may shake with a greater amplitude than short clothes when placed on the moving hanger (500) and the moving hanger (500) is driven, and may prevent the light sensor (700) from receiving light from the light emitting unit (600).

[0394] In this case, even though the long garment is maintained in a state of being placed on the moving hanger (500) and has not fallen, a situation may occur in which the light sensor (700) temporarily detects that the light intensity received from the light emitting unit (600) is higher than the normal value.

[0395] Figure 21 illustrates a situation where long clothing causes abnormal illuminance.

[0396] Referring to Fig. 21(a), when the moving hanger (500) vibrates or the blower fan (352) operates, the clothing may shake inside the inner case (200).

[0397] Referring to Fig. 21(b), the clothing can vibrate while being placed on the moving hanger (500) and block some of the light irradiated from the light emitting unit (600) from moving to the sensor unit (700).

[0398] In addition, when the moving hanger (500) is continuously operated, the clothing may repeat a situation in which the sensor unit (700) blocks and then does not block some of the light irradiated from the light emitting unit (600). That is, the situations of Fig. 21(a) and Fig. 21(b) may be repeated.

[0399] As a result, the illuminance value detected by the sensor unit (700) may change. For example, the illuminance value detected by the sensor unit (700) may repeat between an abnormal illuminance value and a normal value.

[0400] This state is not a state in which the clothing has fallen and is a normal state, but when the above-mentioned abnormal illuminance detection step (A1) is performed, a problem may occur in which the sensor unit (700) detects abnormal illuminance and the course is stopped and the stopping step (A2) is performed.

[0401] Accordingly, the clothing treatment device of the present invention can be controlled to prevent the interruption step (A2) from being performed and to continue the course if the clothing is a long garment, even if abnormal illumination occurs in the abnormal illumination detection step (A1).

[0402] Figure 22 illustrates a control method for detecting long clothes by the garment treatment device of the present invention.

[0403] The garment treatment device of the present invention can perform a check step of detecting whether the garment treatment device is a long garment.

[0404] The above inspection step can detect whether the clothing is a long garment longer than a certain length that interferes with the light sensor (700). The long garment can be defined as a garment having a length that interferes at least partly with the light sensor (700) receiving light from the light emitting unit (600) and blocks a portion of the light irradiated from the light emitting unit (600) from reaching the sensor unit (700).

[0405] The above long clothing may correspond to clothing having a height of more than 2 / 3 of the height of the inner case (200), and may have a length such that at least a portion thereof is positioned between the sensor unit (700) and the light-emitting unit (600).

[0406] When the moving hanger (500) is operated while the long clothes are placed on the moving hanger (500), the long clothes vibrate with a certain amplitude or more, thereby temporarily and repeatedly shielding the light sensor (700) or temporarily and repeatedly blocking a portion of the light irradiated from the light emitting unit (600). As a result, as illustrated, the light value detected by the sensor unit (700) may change over time, and specifically, an interference period (T) in which a normal value and an abnormal light value lower than the normal value are repeated may occur.

[0407] The clothing treatment device of the present invention can determine that the clothing is a long garment when the interference section (T) is found.

[0408] Meanwhile, the occurrence of the above interference section (T) may correspond to the state in which the long garment is placed on the moving hanger (500). This is because if the long garment falls from the moving hanger (500) and is not vibrated by the moving hanger (500), the illuminance value does not change.

[0409] Therefore, the clothing treatment device of the present invention can determine that the clothing is a long garment and that the clothing has not fallen when the illuminance value is not maintained at an abnormal illuminance but changes as in the interference section (T). Therefore, the clothing treatment device of the present invention can perform the inspection step simultaneously with the abnormal illuminance detection step (A1), and when the illuminance value changes in the inspection step, even if the illuminance value corresponds to an abnormal illuminance, it can determine that the clothing has not fallen and block the execution of the stop step (A2). That is, the course execution can continue without interruption.

[0410] The garment treatment device of the present invention can perform a check step (S) to check whether the garment is a long garment when the course is performed.

[0411] Since the above inspection step (S) is a step to check whether clothing is placed on the moving hanger (500), operation of the moving hanger (500) may be essential.

[0412] The above inspection step (S) can be viewed as a process of detecting whether the clothing responds to the operation of the moving hanger (500) through the sensor unit (700).

[0413] Accordingly, the above inspection step (S) may include detecting whether the illuminance value detected by the sensor unit (700) during the process of driving the moving hanger (500) maintains a normal value or whether the illuminance value changes.

[0414] In the above inspection step (S), the control unit can determine that the clothing has not fallen from the moving hanger (500) if the illuminance value detected by the sensor unit (700) maintains a normal value or changes while the moving hanger (500) is operating.

[0415] In addition, in the above inspection step (S), when the illuminance value changes, the control unit can determine that the clothing is shaking due to the operation of the moving hanger (500) and interfering with the illuminance value detected by the sensor unit (700). Accordingly, it can be determined that the clothing is a long garment.

[0416] Figure 23 illustrates an embodiment of performing an inspection step of the clothing treatment device of the present invention.

[0417] The garment treatment device of the present invention can perform the above inspection step (S) when the course starts to be performed.

[0418] The above inspection step (S) can perform a driving step (S1) for driving a moving hanger (500).

[0419] The clothing treatment device of the present invention can perform a judgment step (S4) of judging the state of the clothing during the process of performing the driving step (S1).

[0420] The above judgment step (S4) may include a fall judgment step (S4-1) for judging the state in which the clothing has fallen, a long clothing judgment step (S4-3) for judging whether the clothing is long clothing, and a normal judgment step (S4-2) for judging whether the clothing is normally placed on the moving hanger (500) and is not long clothing.

[0421] The clothing treatment device of the present invention can perform a blocking detection step (S2) to detect whether the illuminance value detected by the sensor unit (700) is lower than a normal value in order to perform the judgment step (S4) while performing the driving step (S1).

[0422] The above blocking detection step (S2) may correspond to the above abnormal illuminance detection step (A1).

[0423] Alternatively, it may be considered that there is a section in which the above inspection step (S) and the above abnormal illuminance detection step (A1) overlap at least partially.

[0424] The above blocking detection step (S2) may be a step for detecting whether the illuminance value continues to be in an abnormal illuminance state. The above blocking detection step (S2) may be a step for detecting whether the illuminance value detected by the sensor unit (700) while the moving hanger (500) is operating remains in an abnormal illuminance state that is lower than the normal value.

[0425] If the abnormal illuminance is maintained for a certain period of time in the above blocking detection step (S2), the clothing treatment device of the present invention can perform a drop determination step (S4-1) in which it is determined that the clothing has fallen in the above determination step (S4).

[0426] In this case, the above-mentioned stopping step (A2) may be performed and the course progress may be stopped.

[0427] Meanwhile, the clothing treatment device of the present invention detects an illuminance value detected by the sensor unit (700) that is an abnormal illuminance lower than the normal value, but the abnormal illuminance state may not be maintained for a certain period of time. The certain period of time may be set to 5 seconds or more.

[0428] The clothing treatment device of the present invention can perform a change detection step (S3) to detect whether there is a change in the illuminance value detected by the sensor unit (700).

[0429] If the above clothing is placed on the moving hanger (500) and is affected by the operation of the moving hanger (500), the illuminance value detected by the sensor unit (700) may not be able to maintain an abnormal illuminance state and a normal value may be detected, or the detected abnormal illuminance value itself may change, or even if only the abnormal illuminance is detected, the abnormal illuminance value itself may change.

[0430] In this case, since it can be determined that the clothing is placed on the moving hanger (500), the clothing treatment device of the present invention can perform the long clothing determination step (S4-3) in which it is determined that the clothing is long clothing in the determination step (S4). Accordingly, the control unit of the clothing treatment device of the present invention can determine that the long clothing is placed on the moving hanger (500).

[0431] Meanwhile, if the illuminance value is maintained at a normal value in the driving step (S1), a normal judgment step (S4-2) may be performed in the judgment step (S4) to determine that the clothing is neither a long garment nor in a dropped state but is placed on the moving hanger (500) in a normal state.

[0432] Figure 24 illustrates an embodiment in which the clothing treatment device of the present invention detects the falling of clothing through a sensor unit.

[0433] In general, long garments may be heavier than short garments. Therefore, even if the long garments are placed on the moving hanger (500), they are more likely to fall off the moving hanger (500) than short garments.

[0434] In addition, due to the difference in material, even if the long garment is lighter than the short garment, when the moving hanger (500) is driven, the long garment may vibrate with a different amplitude from the moving hanger (500), and may vibrate with a larger amplitude and a more complex waveform than the short garment.

[0435] As a result, when the moving hanger (500) is driven, the long clothes may be subject to a stronger inertial force than the short clothes, and even if the long clothes are lighter than the short clothes, there is a high possibility that they will come off the moving hanger (500).

[0436] If the above-mentioned long clothing is detached from the above-mentioned moving hanger (500), not only will hot air and steam not be supplied evenly to the clothing, but a specific part of the clothing may be intensively exposed to hot air or steam discharged from the bottom surface of the inner case (200), which may cause damage to the clothing.

[0437] Therefore, the sooner the garment is determined to be a long garment, the more advantageous it may be. Furthermore, if the garment is a long garment, the sooner measures can be taken to prevent it from falling from the moving hanger (500), the more advantageous it may be for its protection and disposal.

[0438] To this end, the garment treatment device of the present invention can perform the above inspection step (S) at the beginning of the course.

[0439] That is, the difference between the above-mentioned blocking step (S2) of the above-mentioned inspection step (S) and the above-mentioned abnormal light detection step (A1) can be seen as the timing of execution.

[0440] The above inspection step (S) can be performed at the beginning of the course, and the above abnormal illumination detection step (A1) can be performed throughout the course.

[0441] For example, the above inspection step (S) can be performed before steam is supplied into the inner case (200). This can prevent long garments from being damaged by steam.

[0442] The above steam can be sprayed inside the inner case (200) from the preheating step (B2). Therefore, the garment treatment device of the present invention can perform the inspection step (S) before the preheating step (S2) is performed.

[0443] Specifically, the clothing treatment device of the present invention can perform a heating step (S1-1) of driving the heater unit (840) when the driving step (S1) is performed.

[0444] The above heating step (S1-1) is a step of simultaneously driving the first heater (841) and the second heater (842), and may correspond to the steam preparation step (B1).

[0445] Additionally, the heating step (S1-1) can be performed until steam is generated and supplied to the inner case (200).

[0446] Meanwhile, the garment treatment device of the present invention can perform a drive blocking step (S1-3) to block the operation of the compressor (343) in the inspection step (S). Since the heater unit (840) is operated to the maximum in the heating step (S1-1), there is no allowable power to drive the compressor (343), and the compressor (343) is operated from the preheating step (B2).

[0447] Accordingly, the above inspection step (S) can perform a drive blocking step (S1-3) in which the drive of the compressor (343) is blocked.

[0448] The above driving step (S1), the heating step (S1-1), and the driving blocking step (S1-3) can be performed simultaneously, and can be performed as is from the blocking step (S2) described above.

[0449] As a result, the inspection step (S) may be performed before the steam is generated when the course starts, and may be performed before the compressor (343) is driven. In addition, the inspection step (S) may be performed while driving the moving hanger (500) during the process in which the heater unit (840) of the compressor (343) is operated at the beginning of the course.

[0450] Figure 25 illustrates an example of the driving method of a moving hanger when the inspection step (S) is performed during the course execution of the garment treatment device of the present invention.

[0451] The clothing treatment device of the present invention can determine as quickly as possible whether the clothing is a long garment by performing the above-mentioned inspection step (S) at the beginning of the course.

[0452] For example, the above inspection step (S) can be performed in the steam preparation step (B1) and can be completed before the preheating step (B2).

[0453] To perform the above inspection step (s), the moving hanger (500) can be driven in the steam preparation step (B1). The moving hanger (500) can be driven together with the heater unit (840).

[0454] Meanwhile, in the inspection step (S) performed at the beginning of the course, such as the steam preparation step (B1), the driving of the moving hanger (500) may be to determine whether the clothing is a long garment and whether the clothing has fallen from the moving hanger (500). Therefore, the moving hanger (500) may be driven at a second speed, which is lower than the first speed, which is the driving speed of the moving hanger (500) when the course is generally performed, in the inspection step (S).

[0455] In this way, during the process of performing the above inspection step (S), the adverse effect of the clothing falling from the moving hanger (500) due to the operation of the moving hanger (500) can be prevented.

[0456] The above second speed may be set to a speed lower than the maximum driving speed of the moving hanger (500) during course execution.

[0457] Additionally, the second speed may correspond to a speed that drives the moving hanger (500) at the lowest speed among the arbitrary courses.

[0458] Alternatively, the second speed may correspond to the speed at which the moving hanger operates on the course that produces the least noise.

[0459] Alternatively, the second speed may correspond to the lowest speed at which the moving hanger (500) can be driven with the minimum output to shake the clothing.

[0460] When the above inspection step (S) is completed, the moving hanger (500) may stop operating, or if the clothing has not fallen from the moving hanger (500), the moving hanger (500) may continue to operate.

[0461] For example, if the operation of the moving hanger (500) is stopped in the steam injection step (B3), the moving hanger (500) can be operated at the first speed when the drying step (B6) is performed.

[0462] Figure 26 illustrates another example of the driving method of the moving hanger when the inspection step (S) is performed during the course execution of the garment treatment device of the present invention.

[0463] In order to avoid redundant explanations, the following description focuses on differences from the previously described embodiments.

[0464] When the clothing treatment device of the present invention drives the moving hanger (500) in the inspection step (S), the moving hanger (500) can be driven at the driving speed of the moving hanger (500) when the course is performed.

[0465] The garment treatment device of the present invention can perform the inspection step (S) while driving the moving hanger (500) at the first speed. Thus, from the inspection step (S), by driving the moving hanger (500), not only can it determine whether the garment is a long garment or has fallen, but it can also shake the garment to remove foreign substances attached to the garment.

[0466] In addition, from the above inspection step (S), the moving hanger (500) can be driven at the first speed to eliminate wrinkles in the clothing.

[0467] That is, the garment treatment device of the present invention can simultaneously perform the above-mentioned inspection step (S) while processing the garment. As a result, the execution time of the course for processing the garment can be shortened.

[0468] The first speed may correspond to the maximum driving speed of the moving hanger when performing the above course.

[0469] Alternatively, the first speed may correspond to an average driving speed of the moving hanger when performing the course.

[0470] Figure 27 illustrates another example of the driving method of the moving hanger when the inspection step (S) is performed during the course execution of the garment treatment device of the present invention.

[0471] In order to avoid redundant explanations, the following description focuses on differences from the previously described embodiments.

[0472] The clothing treatment device of the present invention can operate at the third speed, which is the fastest operating speed, when operating the moving hanger (500) in the above inspection step (S).

[0473] Accordingly, the garment treatment device of the present invention can more quickly determine whether the garment is a long garment and can reliably remove any foreign substances from the garment before the garment is exposed to steam. In addition, the garment treatment device of the present invention can induce the garment to quickly fall if it is not completely placed on the moving hanger (500), thereby prompting the user who ordered the course to take action before it leaves the garment treatment device.

[0474] The above third speed may correspond to the maximum driving speed at which the moving hanger (500) operates when the above course is performed.

[0475] Alternatively, the third speed may correspond to a driving speed that is faster than the maximum driving speed of the moving hanger (500) when the course is performed.

[0476] Alternatively, the third speed may correspond to the maximum speed at which the moving hanger (500) can operate.

[0477] After the moving hanger (500) is driven in the above inspection step (S), when the judgment step (S4) is completed, the driving speed of the moving hanger (500) may be reduced or the driving step (S1) of the moving hanger (500) may be completed.

[0478] Figure 28 illustrates another embodiment of a control method for a clothing treatment device of the present invention.

[0479] The garment treatment device of the present invention can perform a state detection step (T) that detects the overall state of the garment inside the inner case (200) when performing a course.

[0480] In the above state detection step (T), the garment treatment device of the present invention can perform an abnormality detection step (T1) to detect whether the illuminance value detected by the sensor unit (700) is a normal value throughout the course execution process.

[0481] If the illuminance value detected by the sensor unit (700) in the above abnormality detection step (T1) is a normal value, a progress step (T7) for continuously performing the course until the course is completed can be performed.

[0482] If the sensor unit (700) detects abnormal illuminance in the above abnormality detection step (T1), a confirmation step (T2) for confirming whether the clothing is long clothing can be performed.

[0483] The above confirmation step (T2) may be identical to the above inspection step (S), and the above condition detection step (T) may be performed on the premise that the above inspection step (S) has been performed. For example, when the above inspection step (S) is performed and the condition of the clothing is identified, the clothing treatment device of the present invention may perform the above condition detection step (T) to continuously track the condition of the clothing and take appropriate action.

[0484] If it is detected in the above confirmation step (T2) that the illuminance value is abnormal even though the clothing is not a long garment, the clothing treatment device of the present invention can perform a fall detection step (T4) for determining that the clothing has fallen from the moving hanger (500).

[0485] When the above drop detection step (T4) is performed, the clothing treatment device of the present invention can perform a time determination step (T5) for determining whether the time at which the clothing was dropped is before steam injection is completed inside the inner case (200).

[0486] For example, if the above drop detection step (T4) occurs before the above preheating step (B2) or occurs during the above preheating step (B2) and the above spraying step (B3), the garment treatment device of the present invention can immediately perform a stop step (T6) to stop the course.

[0487] The above stop step (T6) may be a step of stopping the operation of the compressor (343) and the heater unit (840).

[0488] The above-mentioned stop step (T6) may be a step in which the operation of the blower fan (352) is stopped, or may correspond to a step in which the operation of the blower fan (352) is permitted for cooling the clothing.

[0489] As a result, the garment treatment device of the present invention can prevent damage to the garment by preventing the garment from being directly exposed to high-temperature steam.

[0490] However, if the drop detection step (T4) is performed after both the preheating step (B2) and the spraying step (B3) are performed in the garment treatment device of the present invention, the garment is no longer exposed to steam, so the progress step (T7) can be performed.

[0491] That is, the garment treatment device of the present invention can continue to operate the compressor (343) and the blower fan (352) when the garment is dropped in a state where there is no possibility of steam being sprayed. As a result, the garment exposed to steam can be dried and deodorized to the maximum extent possible, thereby preventing rotting of the garment and also refreshing the garment to the maximum extent possible.

[0492] As a result, the user can avoid the hassle of having to restart the garment treatment device to reprocess the garment.

[0493] However, if the clothing treatment device of the present invention has information that the clothing is a long garment or has acquired information that the clothing is a long garment in the confirmation step (T2), it can perform a time judgment step (T3) for judging whether the abnormal state of the illuminance value continues for a certain period of time.

[0494] In the time judgment step (T3), if the abnormal state of the above illuminance value does not continue for a certain period of time and the normal value is detected at least once or the normal value is detected repeatedly, the control unit may determine that the long clothes normally placed on the moving hanger (500) are interfering with the sensor unit (700) and perform the above progress step (T7).

[0495] The above schedule time can be set to 5 seconds or more.

[0496] However, in the time judgment step (T3), if the abnormal state of the illuminance value continues for a certain period of time and the normal value is not detected for a certain period of time, the control unit of the clothing treatment device of the present invention can perform a fall detection step (T4) for judging that the long clothing has fallen from the moving hanger (500).

[0497] When the above drop detection step (T4) is performed, the above-described control method can be performed as is.

[0498] Accordingly, in the clothing treatment device of the present invention, if the steam spraying is completed at the time the clothing, whether long or short, is dropped from the moving hanger (500), the course can be performed as is, and if the time the clothing is dropped from the moving hanger (500) is before or during the steam spraying, the course can be stopped as is.

[0499] Figure 29 illustrates another example of use when the garment treatment device of the present invention detects long clothes.

[0500] In the case where the clothing is not a long garment, the clothing treatment device of the present invention can continuously operate the moving hanger (500) even after operating the moving hanger (500) in the preparation step (B1) or the detection step (Q1), even during the process of spraying the steam into the inner case (200).

[0501] However, in the case where the clothing treatment device of the present invention determines that the clothing is a long garment, the moving hanger (500) may be driven in the preparation step (B1) or the detection step (Q1), and the driving of the moving hanger (500) may be stopped during the process of the steam being sprayed into the inner case (200).

[0502] As a result, the garment treatment device of the present invention can set the start and stop times of the moving hanger (500) differently depending on whether the garment is a long garment.

[0503] For example, the garment treatment device of the present invention can perform a detection step (Q1) of detecting whether the garment is a long garment through the illuminance value detected by the sensor unit (700) while driving the moving hanger (500). The detection step (Q1) may be the same as the inspection step (S) described above.

[0504] The above detection step (Q1) can be performed before steam is supplied to the inside of the inner case (200) when the door closes the inner case (200) after the power of the garment treatment device is supplied or when a command to perform the course is input through an input unit or the like.

[0505] If it is detected in the above detection step (Q1) that the garment is a long garment, the garment treatment device of the present invention can perform a stop step (Q2) that blocks the operation of the moving hanger (500) in the above preheating step (B2) and the spraying step (B3). This prevents the possibility of the garment falling before steam is supplied, thereby preventing damage to the garment in advance.

[0506] However, if the clothing is detected as not being a long garment in the above detection step (Q1), the clothing treatment device of the present invention can perform a permitting step (Q3) of driving the moving hanger (500) in at least one of the preheating step (B2) and the spraying step (B3). As a result, the clothing can be shaken during the steam supply process to expose more steam to the clothing, and foreign substances on the clothing can be evaporated by the steam.

[0507] In addition, by adding physical force during the process of moisture absorption into the clothing, wrinkles in the clothing can be effectively removed.

[0508] Figure 30 illustrates an embodiment in which the driving method of a moving hanger changes depending on the length of clothing.

[0509] Referring to Figure 30(a), the clothing treatment device of the present invention operates a preparatory step (B1) of boiling water by driving a heater unit (840) when a course for treating clothing is performed, a preheating step (B2) of driving a compressor (343) and a blower fan (352) when the steam can be supplied to the inside of the inner case (200), and when the temperature inside the inner case (200) rises above a specific temperature, the heater unit

[0510] (840) can be driven to perform a spraying step (B3) for supplying steam to the inside of the inner case (200), a waiting step (B4) for blocking the operation of the compressor (343) and the blower fan (352) to ensure time for the sprayed steam to be absorbed into the clothing, a cooling step (B5) for cooling the heat of the surface of the clothing by first driving the blower fan (352), and a drying step (B6) for drying the clothing by driving the compressor (343) and the blower fan (352).

[0511] Referring to Fig. 30(b), the clothing treatment device of the present invention can minimize the operation of the moving hanger (500) when the clothing is determined to be long clothing through the moving hanger (500) and the sensor unit (700).

[0512] For example, the clothing treatment device of the present invention can drive the moving hanger (500) only in the inspection step (S) or detection step (Q1) and then stop, and drive the moving hanger (500) in the drying step (B6).

[0513] In this way, it is possible to prevent long clothes from coming off or separating from the moving hanger (500), and to minimize noise generated by vibration of the long clothes inside the clothing treatment device.

[0514] The above moving hanger (500) can be driven at a second speed in the inspection step (S) or detection step (Q1), and can be driven at a first speed that is faster than the second speed in the drying step (B6).

[0515] Alternatively, unlike the illustrated example, by operating at the first or third speed in the inspection step (S) or detection step (Q1), the time for detecting long clothes can be minimized and foreign substances or dust can be removed before the long clothes absorb moisture and become heavier.

[0516] Referring to Fig. 30(c), if the clothing is detected as not being a long garment, the moving hanger (500) can be continuously operated without interruption.

[0517] In this way, wrinkle removal, deodorization, and drying of the clothing can be effectively performed.

[0518] The clothing treatment device of the present invention can also continuously maintain the driving speed of the moving hanger (500) when the course is performed.

[0519] In addition, the clothing treatment device of the present invention can vary the driving speed of the moving hanger (500) during the course.

[0520] For example, in the above preparation step (B1), the moving hanger (500) can be driven at a second speed to minimize the possibility of clothing falling and reduce noise.

[0521] In the preheating stage (B2), the moving hanger (500) can be driven at a faster speed than in the preparation stage (B1). Thus, the garment treatment device of the present invention can shake the garment more vigorously in a high-temperature, dry environment, thereby removing dust and foreign substances from the garment. For example, the moving hanger (500) can be driven at the first speed.

[0522] In the above-mentioned spraying step (B3), the moving hanger (500) can be driven again more slowly than in the preheating step (B2). This allows steam to reach the surface of the clothing more reliably, thereby increasing the moisture content of the clothing and preventing the clothing from falling off the moving hanger (500).

[0523] The above-mentioned waiting stage (B4) and cooling stage (B5) can be operated by the moving hanger (500) at the fastest speed. This allows the clothing to be cooled more quickly. For example, the moving hanger (500) can be operated at a third speed.

[0524] In the above drying step (B6), the moving hanger (500) may be operated at a slower speed than in the waiting step (B4) and cooling step (B5). For example, the moving hanger (500) may be operated at a first speed that is slower than the third speed. As a result, the wrinkle removal, deodorization, and dust removal performance of the moving hanger (500) are secured, while the overload of the clothing treatment device is prevented.

[0525] In addition, considering that the drying step (B6) can be performed longer than other steps, the amount of noise generated from the clothing treatment device and the duration of noise generation can be reduced.

[0526] In this way, the garment treatment device of the present invention can determine whether the garment is a long garment from the beginning of the course and set a different control method for the course depending on whether the garment is a long garment.

[0527] The present invention may be implemented in various modified forms, and the scope of the invention is not limited to the above-described embodiments. Therefore, if a modified embodiment includes elements of the claims of the present invention, it should be considered to fall within the scope of the present invention.
