Description

Garment treatment device and method for controlling the garment treatment device

[0001] The present invention relates to a clothing treatment device for drying clothes.

[0002] Clothes treatment devices, such as dryers, are equipped with a circulating duct that circulates air inside a drum containing clothes, first cooling it to condense moisture, then reheating it to generate high-temperature hot air that is then injected back into the drum. This circulating air inside the drum allows for continuous drying of moisture contained in the clothes.

[0003] These dryers have the advantage of being able to continuously dry a large number of clothes without changing the humidity or temperature outside the dryer, as the inflow of outside air or the discharge of air inside the drum to the outside is blocked or minimized.

[0004] However, as the clothing dries, not only does moisture evaporate, but foreign substances such as lint and fluff are also separated from the clothing by the hot air. These separated foreign substances may re-attach to the clothing as they continuously circulate through the drum and circulation section, or may adhere to heat exchangers that cool or heat the air.

[0005] Over time, these stuck foreign objects can grow in size and block the airflow through the circulating fluid, and the high temperature and moisture environment can cause bacteria to grow and rot.

[0006] Therefore, Korean Patent Registration No. 10-1806241 and Korean Patent Publication No. 10-2021-0114092 attempted to solve the above-described problem by disclosing a structure capable of automatically washing the foreign substance with water.

[0007] However, these dryers had a problem in that water was not completely discharged from the washing section that supplied water to the circulation section and remained there.

[0008] In addition, since water discharged from clothing or water supplied through a conduit connected to an external water source remains, there were limitations such as hygiene issues due to fungal growth in the residual water inside the nozzle and reliability issues due to limescale coagulation.

[0009] The present invention aims to provide a clothing treatment device in which the washing reliability of a heat exchanger or a circulation path is improved.

[0010] The present invention aims to provide a clothing treatment device that minimizes water remaining in a washing unit that supplies washing water to a heat exchanger or a circulation flow unit.

[0011] The purpose of the present invention is to provide a clothing treatment device equipped with a washing unit that is easy to maintain and has increased washing efficiency.

[0012] The purpose of the present invention is to provide a clothing treatment device that improves hygiene and reliability by minimizing water remaining in a washing section.

[0019] The above control unit can open the main valve and the supply valve, block the steam valve, and then, after a preset time has elapsed, block the main valve and open the supply valve and the steam valve.

[0020] The above moving pipe includes a moving valve that controls the steam moving to the steam nozzle and whose opening and closing are controlled by the control unit, and the control unit can control the moving valve to be blocked when the steam moves from the steam generating unit to the direct nozzle.

[0021] The position at which the steam pipe is connected to the steam case may be higher than the maximum water level that can be accommodated inside the steam case.

[0022] The above moving pipe is provided with greater resistance than the steam pipe, and the steam generated in the steam supply unit can be induced to flow into the steam pipe.

[0023] The above-mentioned direct water nozzle is internally partitioned to divide the area inside the circulation path and supply water, and at least two supply valves can be provided so as to selectively supply water to each partitioned area of ​​the above-mentioned direct water nozzle.

[0024] The above control unit can supply water to each partitioned area of ​​the direct nozzle by alternately opening the supply valves.

[0025] The above circulation flow section is arranged and extended so as to be biased toward one side of the drum, and the direct nozzle is arranged so as to cross the direction in which the air moves within the circulation flow section so as to discharge water across the entire width direction of the circulation flow section, and the direct nozzle can be partitioned along the width direction of the circulation flow section.

[0026] The above-mentioned direct nozzle can discharge more water, discharge water for a longer period of time, or discharge water more forcefully on one side of the above-mentioned circulation path than on the other side.

[0057] Figure 1 illustrates the appearance of the clothing treatment device of the present invention.

[0058] A garment treatment device according to one embodiment of the present invention may include a cabinet (100) forming an exterior.

[0059] The cabinet (100) may include a front panel (110) forming the front surface of the garment treatment device, an upper panel (150) forming the upper surface, and a side panel (140) forming the side surface. The side panel (140) may include a left panel (141) forming the left surface and a right panel opposite thereto. The front panel (110) may be provided with an opening (111) provided to communicate with the interior of the cabinet (100), and a door (130) rotatably coupled to the cabinet (100) to open and close the opening (111).

[0060] An operation panel (117) may be installed on the front panel (110). The operation panel (117) may be equipped with an input unit (118) for receiving control commands from a user, and a display unit (119) for outputting control commands selectable by the user and information displayed by the garment treatment device.

[0061] A control unit may be installed inside the cabinet (100) to control the internal configuration to execute the control command input through the input unit (118). The control unit (190) may be connected to the internal configurations of the garment treatment device and control the corresponding configurations to execute the input command.

[0062] The above control command may include a command to supply power to the garment treatment device, a command to select a drying course or drying option capable of performing a series of drying operations, and a command to execute the drying course and drying option. The input unit (118) may be provided to include a power supply request unit that requests power supply to the garment treatment device, a course input unit that allows the user to select a desired course from among a plurality of courses, and an execution request unit that requests the start of the course selected by the user.

[0063] The above display unit (119) may be provided to include at least one of a display panel capable of outputting text and shapes, and a speaker capable of outputting voice signals and sounds.

[0064] Meanwhile, the garment treatment device of the present invention may include a water storage tank (120) that is provided to separately store water condensed during the drying process of the garment. The water storage tank (120) may include a handle that is provided so as to be withdrawn to the outside from one side of the front panel (110).

[0065] The user can remove the water tank (120) from the cabinet (100), remove the condensate, and then re-install it in the cabinet (100). Thus, the garment treatment device of the present invention can be installed even in places where a sewer or the like is not installed.

[0066] For example, the water storage tank (120) may be placed on top of the door (130). In this case, there is an advantage in that the user can easily withdraw the water storage tank (120).

[0067] Figure 2 illustrates the internal configuration of the clothing treatment device of the present invention.

[0068] The clothing treatment device of the present invention may include a drum (200) accommodated inside the cabinet (100) to accommodate clothing, a driving unit (500, 600) that rotates the drum (200), a heat exchange unit (900) that supplies hot air to the drum (200), and a base (800) that is provided with a circulation path unit (820) that provides a space for the hot air to move.

[0069] The above circulation path (820) may be provided to communicate with the front and rear of the drum, respectively. As a result, air discharged from the drum (200) may be supplied to the circulation path (820), and air discharged from the circulation path (820) may be supplied back to the drum (200).

[0070] The above driving unit (500, 600) may be directly connected to the drum (200) to rotate the drum (200). For example, the driving unit (500, 600) may be provided as a DD (Direct Drive unit) type. Accordingly, the driving unit (500, 600) can control the rotational direction or rotational speed of the drum (200) by directly rotating the drum (200) without the need for a belt or pulley.

[0071] The above driving unit (500, 600) may include a motor unit (500) that receives electric power and provides power to rotate the drum (200). The motor unit (500) may rotate at a high RPM. For example, the motor unit (500) may rotate at a much higher RPM than the RPM at which the clothes inside the drum (200) can rotate while remaining attached to the inner wall of the drum (200). However, if the clothes inside the drum (200) are continuously attached to the inner wall of the drum (200) and rotate, the drying efficiency may decrease because the portion attached to the inner wall of the drum is not exposed to hot air. On the other hand, if the rotor (520) is rotated at a low RPM so that the clothes inside the drum (200) roll or stir without being attached to the inner wall of the drum (200), a problem may arise in that the output or torque that the driving unit (500, 600) can generate may not be properly utilized.

[0072] To solve this problem, the driving unit (500, 600) of the garment treatment device of the present invention may further include a reducer (600) that can increase torque while utilizing the maximum output of the motor unit (500) by reducing the RPM.

[0073] The above reducer (600) may include a drum rotation shaft (6341) that receives power from the motor (500) and rotates the drum (200).

[0074] The above drum (200) may be manufactured in a form in which a drum body (210) having a cylindrical shape and accommodating clothing is combined with a drum back surface (220) that is coupled to the rear of the drum body (210) to form the rear surface of the drum (200).

[0075] An inlet (211) for clothes to enter and exit may be provided at the front of the drum body (210). A driving unit (500, 600) for rotating the drum may be connected at the rear of the drum back surface (220).

[0076] The drum body (210) and the drum back surface (220) can be joined by a fastening member such as a bolt, or joined by bending each other using a method such as seaming, or joined by a method such as welding.

[0077] A lift (213) for pulling clothing upward may be provided on the inner surface of the drum body (210). Clothing accommodated inside the drum (200) may be evenly exposed to hot air by repeatedly rising and falling by the lift (213).

[0078] A reinforcing bead (212) may be formed along the perimeter of the drum body (210). The reinforcing bead (212) may be formed by being sunken or protruding from the drum body (210). A plurality of such reinforcing beads may be provided, and may be provided spaced apart from each other.

[0079] When the above reinforcing beads (212) are provided, the gap between the clothing and the drum body (210) can be increased, so that the hot air supplied to the drum (200) can be more effectively introduced between the clothing and the drum (200). As a result, the durability of the drum can be increased by the reinforcing beads, and the drying efficiency of the clothing treatment device can be improved.

[0080] Typically, in the case of a DD type washing machine, the driving unit (500, 600) is fixedly coupled to a tub that accommodates the drum (200), and the drum (200) can be supported by the tub while being coupled to the driving unit (500, 600). However, since the garment treatment device of the present invention is equipped to intensively perform a drying cycle, the tub fixed to the cabinet (100) to accommodate the drum (200) is omitted.

[0081] The garment treatment device of the present invention may further include a separate support member (400) to fix or support the drum (200) or the driving member (500, 600) inside the cabinet (100) without such a tub.

[0082] The above support member (400) may include a front plate (410) positioned in front of the drum (200) and a rear plate (420) positioned in the rear of the drum (200).

[0083] The front plate (410) and the rear plate (420) may be provided in a plate shape and may be arranged to face the front and rear of the drum (200), respectively. The distance between the front plate (410) and the rear plate (420) may be set to be equal to the length of the drum (200) or longer than the length of the drum (200). The front plate (410) and the rear plate (420) may be fixed to and supported by the bottom surface or base (800) of the cabinet (100).

[0084] The front plate (410) may be placed between the front panel forming the front surface of the cabinet and the drum (200). In addition, the front plate (410) may be provided with an input communication hole (412) communicating with the input port (211).

[0085] The front plate (410) may be provided with a duct connection part (416) that connects the lower side of the injection communication hole (412) and the circulation flow part (820), and a duct communication hole (417) that is positioned inside the duct connection part (416) and through which air flowing in from the injection communication hole (412) can move.

[0086] A filter that filters air flowing into the duct connection hole (417) can be installed in the above duct connection portion (416).

[0087] In order to avoid the input port (211), it is preferable that the above driving unit (500, 600) be installed on the rear plate (420) rather than the front plate (410).

[0088] The above driving unit (500, 600) can be mounted and supported on the rear plate (420). As a result, the driving unit (500, 600) can rotate the drum (200) while its position is stably fixed through the rear plate (420).

[0089] At least one of the front plate (410) and the rear plate (420) can rotatably support the drum (200) through a support wheel (415) or the like.

[0090] For example, the front of the drum (200) can be rotatably supported by a roller provided on the front plate (410), and the rear of the drum (200) can be supported by the rear plate (420) by the support wheel (415) provided on the rear plate (420) as well as the driving unit (500) mounted on the rear plate (420).

[0091] The above support wheel (415) may be rotatably provided on the back surface of the front plate (410). The support wheel (415) may be rotated while in contact with the lower outer surface of the drum body (210).

[0092] The above support wheel (415) can reduce the load applied to the drum rotation shaft (6341). Accordingly, the drum rotation shaft (6341) can be prevented from bending and noise generated by vibration can be prevented.

[0093] The circulation path (820) provided in the above base (800) can form a path for circulating the air inside the drum (200) and then reintroducing it into the drum (200).

[0094] The above circulation path (820) may include an inlet duct (821) into which air discharged from the drum (200) is introduced, an exhaust duct (823) that supplies air to the drum (200), and a moving duct (822) that connects the inlet duct (821) and the exhaust duct (823).

[0095] When air is discharged from the front of the drum (200), the moving duct (822) may be located on the front side of the circulation path (820). And the discharge duct (823) may be located on the rear side of the circulation path (820).

[0096] A duct cover (830) is coupled to the upper side of the circulation passage (820) to partially shield the open upper surface of the circulation passage (820). The duct cover (830) can prevent air from leaking out of the circulation passage (820). In other words, the duct cover (830) can form one side of the passage through which air circulates.

[0097] In addition, the heat exchange unit (900) provided in the base (800) may include an evaporator (910) provided inside the circulation path unit (820) to cool air and a condenser (920) provided inside the circulation path unit (820) to heat air cooled in the evaporator (910).

[0098] The above evaporator (910) dehumidifies air discharged from the drum (200), and the condenser (920) can heat the dehumidified air. The heated air can be supplied back to the drum (200) to dry clothes contained in the drum (200).

[0099] The above evaporator (910) and the condenser (920) may be provided as heat exchangers through which refrigerant flows. The refrigerant moving along the evaporator (910) and the condenser (920) may be provided to exchange heat with air discharged from the drum (200).

[0100] The heat exchange unit (900) may further include a circulation fan (950) installed in the circulation flow unit (820) to generate air flow inside the circulation flow unit (820), and a circulation fan motor (951) to rotate the circulation fan (950). The circulation fan (950) may be rotated by receiving rotational power from the circulation fan motor (951). The circulation fan (950) may be provided to move air that has passed through the evaporator (910) to the condenser (920).

[0101] The circulation fan (950) may be installed in any one of the inlet duct (821), the moving duct (822), and the exhaust duct (823). The circulation fan (950) may be arranged at the rear of the circulation section (820) to move air from the front to the rear through negative pressure.

[0102] A rear plate (420) may be provided at the rear of the drum (200) to guide air discharged from the circulation path (820) to the drum (200). The rear plate (420) may be provided to be spaced apart from the rear surface (220) of the drum.

[0103] The above circulation path (820) can receive air from inside the drum (200) through the front plate (410) and supply air to the drum (200) through the rear plate (420). Air discharged from the circulation path (820) can pass through the rear plate (420) and be guided to the drum (200).

[0104] The above exhaust duct (8231) may further include a blower duct for exhausting air. The air exhausted through the blower duct may move along the rear plate (420) and be guided to the drum (200).

[0105] Figure 3 is an exploded perspective view of the internal configuration of the garment treatment device.

[0106] The above base (800) may further include a connector (850) that guides the air discharged from the circulation path (820) to the rear plate (420). The connector (850) may guide the discharged air to be evenly distributed throughout the entire rear plate (420).

[0107] The connector (850) may be arranged on the upper portion of the exhaust duct (823) to guide the heated hot air passing through the condenser (920) upward from the exhaust duct (823). In addition, the connector (850) may be coupled to an opening provided on the upper portion of the blower duct (8231). The connector (850) may be arranged to form a flow path therein. The connector (850) may be arranged to evenly guide the flow of air generated by the circulation fan to the rear plate (420). That is, the connector (850) may be arranged to have an area of ​​the flow path that increases as it gets farther from the blower duct (8231).

[0108] The above circulation fan (950) may be installed in the air blower duct (8231). In addition, the circulation fan motor (951) may be positioned at the rear of the air blower duct (8231). When the circulation fan (950) rotates by the circulation fan motor (951), the air inside the circulation flow path (820) may be discharged to the outside of the circulation flow path (820) through the air blower duct (8231).

[0109] The above connector (850) can be installed in the air duct (8231). That is, the connector (850) can guide air discharged from the air duct (8231) to the rear plate (420). The hot air supplied to the rear plate (420) can be introduced into the interior of the drum (200) through the drum rear surface (220).

[0110] The drum (200) of the garment treatment device of the present invention is not rotated indirectly by being coupled to a belt or the like, but can be rotated by being directly connected to a driving unit located at the rear of the drum (200). Therefore, unlike the drum of a conventional dryer which is provided in a cylindrical shape with the front and rear open, the rear of the drum of the garment treatment device of the present invention is shielded and can be directly coupled to the driving unit (500, 600).

[0111] The drum back surface (220) may be provided to shield the rear of the drum body (210) and provide a coupling surface that is directly coupled to the driving unit (500, 600). That is, the drum back surface (220) may be provided to be connected to the driving unit (500, 600) and receive rotational power to rotate the entire drum (200). As a result, an input port (211) for inserting clothes may be formed at the front of the drum body (210) and the rear may be shielded by the drum back surface (220).

[0112] The drum back surface (220) may be provided with a bushing (300) that connects the driving unit (500, 600) and the drum back surface (220). The bushing (300) may be provided on the drum back surface (220) to form a center of rotation of the drum (200). The bushing (300) may be provided as an integral part with the drum back surface (220), but may be provided with a material that has greater rigidity or durability than the drum back surface (220) in order to be firmly connected to the rotation shaft that transmits power. The bushing (300) may be mounted and connected to the drum back surface (220) so as to be coaxial with the center of rotation of the drum back surface (220).

[0113] The drum back surface (220) may include a peripheral portion (221) coupled to the outer surface of the drum body (210) and a mounting plate (222) provided on the inner side of the peripheral portion (221) and capable of being coupled to the driving unit (500, 600). The bushing portion (300) may be seated and coupled to the mounting plate (222). The rotational axis for rotating the drum is coupled to the mounting plate (222) through the bushing portion (300), thereby providing an effect of more secure coupling. In addition, deformation of the drum back surface (220) may be prevented.

[0114] The drum back surface (220) may include a suction hole (224) formed through a penetration between the peripheral portion (221) and the mounting plate (222) and connecting the front and rear surfaces of the drum back surface (220). Hot air supplied through the circulation passage (820) may be introduced into the drum body (210) through the suction hole (224). The suction hole (224) may be provided as a plurality of holes formed through the drum back surface (220) or may be provided as a mesh-shaped net.

[0115] A driving unit for rotating the drum (200) may be installed at the rear of the rear plate (420). A motor unit (500) may be placed at the rear of the rear plate (420). In addition, the motor unit (500) may be coupled to the rear of the rear plate (420) via the reducer (600).

[0116] The above-described reducer (600) is fixed to the rear surface of the rear plate (420), and the motor unit (500) can be coupled to the rear surface of the reducer (600). That is, the rear plate (420) can provide a support surface on which the reducer (600) or the motor unit (500) is supported. However, the present invention is not limited thereto, and the motor unit (500) can also be coupled to the rear plate (420).

[0117] A garment treatment device according to one embodiment of the present invention may include a rear cover (430) coupled to the rear plate (420) to prevent the motor unit from being exposed to the outside.

[0118] The front plate (410) may include a front panel (411) forming a front surface, and an input communication hole (412) formed to penetrate the front panel (411) and communicate with the drum (200). The front plate (410) may be provided on the back surface of the front panel (411), and a front gasket (413) may be provided to surround the radially outer side of the input communication hole (412) and accommodate a portion of the drum body (210).

[0119] The front gasket (413) can rotatably support the drum body (210) and can be provided so as to be in contact with the outer or inner surface of the inlet (211). The front gasket (413) can prevent hot air inside the drum (200) from leaking between the drum body (210) and the front plate (410). The front gasket (413) can be provided with a plastic resin series or an elastic body, and a separate sealing member can be additionally coupled to the front gasket (413) to prevent clothes or hot air from escaping from the drum body (210) to the front plate (410).

[0120] The front plate (410) may be provided with a water tank support hole (414) that penetrates the front panel (411) and allows a water tank (120) for storing condensate generated during the drying process to be withdrawn or supported. If the water tank support hole (414) is provided on the upper side, the user does not have to bend over when withdrawing the water tank, which increases the convenience of the user.

[0121] The drum back surface (220) may further include a reinforcing rib (225) extending from the peripheral portion (221) toward the center of rotation. The reinforcing rib (225) may extend to avoid the suction hole (224). The reinforcing rib (225) has the effect of preventing the rigidity of the drum back surface (220) from being reduced due to the suction hole (224). The reinforcing rib (225) may be provided to extend radially from the outer peripheral surface of the mounting plate (222) toward the inner peripheral surface of the peripheral portion (221).

[0122] In addition, the drum back surface (220) may further include a circumferential rib (227) that extends in the circumferential direction of the drum back surface (220) to connect the reinforcing ribs (225) to each other. The suction hole (224) may be arranged between each reinforcing rib (225), the circumferential rib (227), and the peripheral portion (221). The reinforcing rib (225) and the circumferential rib (227) have the effect of preventing the drum back surface (220) from being deformed even when rotational force is transmitted from the motor unit (500).

[0123] The above inlet duct (821) may be provided to communicate with the duct communication hole (417) of the front plate (410) and the flow path installed inside the front plate (410). The moving duct (822) may be provided to extend from the end of the inlet duct (821) toward the rear of the drum (200), and the exhaust duct (823) may be provided at the end of the moving duct (822) to guide the air to the drum (200).

[0124] The above-mentioned blower duct (8231) may be located downstream of the above-mentioned exhaust duct (823), and the blower duct (8231) may provide a space in which a circulation fan is installed. When the circulation fan operates, air drawn into the inlet duct (821) may be discharged to the upper portion of the blower duct (8231).

[0125] The above heat exchange unit (900) may include a compressor (930) connected to the evaporator and the condenser to supply compressed refrigerant. The compressor (930) may be provided so as not to directly exchange heat with the circulating air, and thus may be located outside the circulation path unit (820).

[0126] The rear plate (420) may be coupled to the base (800) or supported by the base (800) and positioned at the rear of the drum (200). The rear plate (420) may include a rear panel (421) positioned to face the front plate (410), a duct section (423) provided to be recessed in the rear panel (421) to form a flow path for air and to guide air discharged from the circulation flow section (820) to the drum.

[0127] The above rear plate (420) may include a mounting portion (425) to which the driving portion (500, 600) is coupled or supported. The mounting portion (425) may be provided to penetrate the rear panel (421) and may be arranged on the inner circumference of the duct portion (423). The mounting portion (425) may be provided to be spaced radially inward from the inner circumference of the duct portion (423).

[0128] The above driving unit (500, 600) can be mounted on the mounting unit (425). The mounting unit (425) can support the load of the driving unit (500, 600). The driving unit (500, 600) can be connected to the drum (200) while being supported by the mounting unit (425).

[0129] The above duct portion (423) may be provided to accommodate a portion of the drum back surface (220). The duct portion (423) may form a path through which air moves together with the drum back surface (220).

[0130] The above driving unit (500, 600) may be installed in the mounting unit (425) so as to prevent interference with the duct unit (423). That is, the driving unit (500, 600) may be positioned radially inwardly from the inner circumferential surface of the duct unit (423). The driving unit (500, 600) may be installed in the mounting unit (425), but may be installed so that the rear side is exposed to the outside so as to be cooled by external air.

[0131] The above motor unit (500) may include a stator (510) that generates a rotating magnetic field and a rotor (520) that is provided to rotate by the stator (510).

[0132] The rotor (520) may be provided as an outer rotor type that accommodates the stator (510) and is configured to rotate around the circumference of the stator (510). At this time, a drive shaft may be coupled to the rotor (520) and may be directly connected to the drum (200) by penetrating the stator (510) and the mounting portion (425). In this case, the rotor (520) may directly transmit power to rotate the drum (200).

[0133] The above rotor (520) can be coupled to the drive shaft through the washer portion (540). The washer portion (540) can perform the function of connecting the drive shaft and the rotor (520). Since the contact area between the rotor (520) and the drive shaft can be increased by the washer portion (540), there is an effect of more effectively transmitting the rotation of the rotor (520).

[0134] The above reducer (600) may be provided to connect the motor unit (500) and the drum (200). The reducer (600) may convert the power of the motor unit (500) to rotate the drum (200). The reducer (600) may be arranged between the motor unit (500) and the drum (200) to receive the power of the motor unit (500), convert it, and transmit it to the drum (200). The reducer (600) may be provided to convert the RPM of the rotor into a small RPM, increase the torque value, and transmit it to the drum (200).

[0135] Specifically, the reducer (600) may be coupled with a drive shaft that is coupled with the rotor (520) and rotates together with the rotor (520). The reducer (600) includes a gear combination that is internally engaged with the drive shaft and rotates to change the rpm of the drive shaft while increasing the torque, and the gear combination may be connected to a drum rotation shaft that is coupled to the drum (200) and rotates the drum. Therefore, when the drive shaft (530) rotates, the drum rotation shaft rotates at a slower rpm than the drive shaft, but can rotate with a greater torque.

[0136] The performance of this reducer (600) may depend on whether the drive shaft and the drum rotation shaft can maintain coaxiality. If the drive shaft and the drum rotation shaft are misaligned with each other, there is a risk that the components constituting the gear assembly inside the reducer (600) may become loose or disengaged from at least one of the drive shaft and the drum rotation shaft. Accordingly, the power of the drive shaft may not be properly transmitted to the drum rotation shaft, or the drive shaft may spin. In addition, if the drive shaft and the drum rotation shaft are misaligned even temporarily, the gears inside the reducer (600) may become misaligned and collide with each other, resulting in unnecessary vibration or noise. In addition, if the angle at which the drive shaft and the drum rotation shaft are misaligned even temporarily becomes severe, there is a risk that the reducer (600) may completely move out of its proper position or be damaged.

[0137] To prevent this, it is preferable that clothes treatment devices equipped with a reducer fix the reducer (600) and the motor unit (500) to a support that maintains its original state without deformation even when an external force is applied. For example, in the case of a washing machine, a method may be applied in which the tub accommodating the drum is first fixed to a cabinet, and then the motor unit and the reducer are secondarily fixed to a bearing housing made of a rigid body that is built into the tub by injection molding.

[0138] However, since the clothes treatment device of the present invention is equipped with a dryer, the configuration of a tub fixed inside the cabinet is omitted. In addition, since the back panel of the cabinet is equipped with a relatively thin plate, even if the stator (510) is fixed, the back panel can easily vibrate or bend due to the repulsive force when the rotor (520) rotates. If the back panel vibrates or bends even temporarily, a problem may occur in which the centers of rotation of the reducer (600) and the motor unit (500), which are arranged in combination with the drum (200), are misaligned with each other.

[0139] It may be considered that the stator (510) is coupled to the rear plate (420) to support the motor unit (500). When a large amount of clothing is accommodated inside the drum (200) or eccentricity occurs, the drum rotation axis may be twisted along the arrangement of the clothing each time the drum (200) rotates. At this time, since the stator (510) is separated from the drum (200) and fixed to the rear plate (420), the drum rotation axis may vibrate at a different width or tilt at a different angle from the stator (510). Therefore, the coaxiality of the drum rotation axis and the drive shaft may not be maintained.

[0140] To solve this problem, the garment treatment device of the present invention can fix the motor unit (500) by coupling it to the reducer (600). In other words, the reducer (600) itself can serve as a reference point for the entire driving unit. That is, the reducer (600) can serve as a reference for the vibration and inclination angle of the entire driving unit (500, 600).

[0141] Since the motor unit (500) is not fixed to other components of the garment treatment device but is only fixed to the reducer (600), when vibration or external force is transmitted to the driving unit (500, 600), when the reducer (600) tilts or vibrates, the motor unit (500) can always tilt or vibrate simultaneously with the reducer (600). As a result, the reducer (600) and the motor unit (500) can form a single vibration system, and the reducer (600) and the motor unit (500) can be maintained in a fixed state without moving relative to each other.

[0142] Among the motor section (500), the stator (510) can be directly coupled to and fixed to the reducer (600). As a result, the position at which the drive shaft (530) is installed relative to the reducer (600) may not change. The center of the drive shaft (530) and the center of the reducer (600) may be arranged to coincide with each other, and the drive shaft (530) may rotate while maintaining the same axis as the center of the reducer (600).

[0143] The first axis (M1) may refer to an imaginary line extending in the forward and backward direction along the center of rotation of the drum (200). That is, the first axis (M1) may be provided parallel to the X-axis.

[0144] The second axis (M2) and the third axis (M3) may refer to imaginary lines extending from the front to the rear upper side of the garment processing device. That is, the second axis (M2) and the third axis (M3) may be provided parallel to the XZ plane or orthogonal to the Y axis.

[0145] The first axis (M1) and the second axis (M2) can intersect each other in the reducer (600). In addition, the first axis (M1) and the third axis (M3) can intersect in the mounting portion (425).

[0146] The above reducer (600) and the above motor unit (500) can be designed to be arranged along the first axis (M1) parallel to the ground when there is no load on the drum (200) or the above motor unit (500) is not operating.

[0147] However, when vibration occurs in the drum (200) or motor unit (500), the vibration is transmitted to the reducer (600), causing the reducer (600) to tilt, thereby temporarily causing the reducer (600) to tilt along the second axis (M2).

[0148] At this time, since the motor unit (500) is coupled to the reducer (600), it can vibrate or tilt together with the reducer (600). Accordingly, the motor unit (500) can be arranged parallel to the reducer (600) on the second axis (M2). Accordingly, the driving shaft and the drum rotation shaft can also be arranged parallel along the second axis (M2).

[0149] As a result, even if the reducer (600) is tilted, the motor unit (500) can move integrally with the reducer (600), and the driving shaft and the drum rotation shaft can maintain coaxiality.

[0150] The above-described reducer (600) may be fixedly coupled to the rear plate (420). In this case, since the reducer (600) will tilt or vibrate while being coupled to the rear plate (420), it can be seen that the rear plate (420) serves as the center of a vibration system including the reducer (600), the motor unit (500), and the drum (200). In this case as well, the motor unit (500) may not be directly coupled to the rear plate (420), but may be fixedly coupled only to the reducer (600).

[0151] The above reducer (600), the motor unit (500), and the drum (200) are arranged in parallel along the first axis (M1), and the reducer (600) can be inclined parallel to the third axis (M3) by vibration of the drum (200) or the motor unit (500). The third axis (M3) can pass through the reducer (600) coupled to the rear plate (420). At this time, since the reducer (600) and the motor unit (500) are coupled, the motor unit (500) can also be inclined parallel to the third axis (M3) in the same manner as the reducer (600).

[0152] Finally, the motor unit (500) and the drum (200) are coupled to the reducer (600), so that the motor unit (500) and the drum (200) can tilt parallel to each other or vibrate simultaneously with respect to the reducer (600).

[0153] Since the above drive shaft (530) rotates relative to the reducer (600) but is fixed to prevent tilting, and the stator (510) is also fixed to the reducer (600), the gap between the stator (510) and the rotor (520) can always be maintained. As a result, collision between the stator (510) and the rotor (520) can be prevented, and noise or vibration that may occur due to the center of rotation of the rotor (520) changing while rotating the stator (510) can be fundamentally blocked.

[0154] The drum rotation shaft (6341) is provided to extend toward the drum (200) from within the reducer (600), and can vibrate and tilt together with the reducer (600). That is, the drum rotation shaft (6341) is provided to rotate in the reducer (600), but the installed position can be fixed. As a result, the drum rotation shaft (6341) and the drive shaft (530) can always be arranged in parallel and form a coaxial connection. In other words, the center of the drum rotation shaft (6341) and the center of the drive shaft (530) can be maintained in a state where they are aligned with each other.

[0155] A sealing portion (450) may be provided between the drum back surface (220) and the rear plate (420). The sealing portion (450) may seal the space between the drum back surface (220) and the rear plate (420) so that air introduced into the duct portion (423) of the rear plate (420) is prevented from leaking out and is introduced into the suction hole (224).

[0156] The above sealing portion (450) may be arranged on each of the outer and inner surfaces of the duct portion (423). A first sealing portion (451) may be provided on the radially outer side of the duct portion (423), and a second sealing portion (452) may be provided on the radially inner side. The first sealing portion (451) may prevent hot air from leaking outward in the radial direction between the drum back surface (220) and the duct portion (423), and the second sealing portion (452) may prevent hot air from leaking outward in the radial direction between the drum back surface (220) and the duct portion (423).

[0157] In other words, the sealing portion (450) may be respectively positioned on the radially outer and inner sides of the suction hole (224). The first sealing portion (451) may be positioned on the radially outer side of the suction hole (224), and the second sealing portion (452) may be positioned on the radially inner side of the suction hole (224).

[0158] In order to prevent hot air from leaking out, the sealing portion (450) is preferably provided to contact both the drum back surface (220) and the rear plate (420). Since the drum (200) rotates during the operation of the clothing treatment device, continuous friction is applied to the sealing portion (450) by the drum back surface (220). Therefore, it is preferable that the sealing portion (450) be provided with a material that can seal between the drum back surface (220) and the duct portion (423) without deteriorating in performance even with the frictional force and frictional heat generated by the rotation.

[0159] In order to install the above-described reducer (600), motor unit (500), etc., the rigidity of the rear plate (420) needs to be secured. To this end, the rear plate (420) may further include a bracket (700) to reinforce the coupling rigidity. The bracket (700) may be additionally coupled to the rear plate (420), and the reducer (600) and the motor unit (500) may be coupled to the rear plate (420) by the bracket (700).

[0160] The above-mentioned reducer (600) can be simultaneously coupled with the bracket (700) and the rear plate (420). For example, the reducer (600), the rear plate (420), and the bracket (700) can be simultaneously coupled by using a fastening member. The rear plate (420) can be rigidly coupled with the bracket (700). The reducer (600), the motor unit (500), etc. can be coupled to the rear plate (420) with secured rigidity.

[0161] The reducer (600) may be first coupled to the above bracket (700) and then the bracket (700) may be coupled to the rear plate (420). That is, the reducer may not be directly coupled to the rear plate (420) but may be fixed to the rear plate (420) through the bracket (700).

[0162] When the motor unit (500) or the reducer (600) is coupled to the rear of the rear plate (420), the motor unit (500) and the reducer (600) may be exposed to the outside. Therefore, it is necessary to prevent the motor unit (500) from being exposed by being coupled to the rear of the rear plate (420). In addition, the duct unit (423) may be heated by hot air. Therefore, it may be necessary to insulate the rear surface of the duct unit (423).

[0163] The rear cover (430) can be coupled to the rear of the rear plate (420) to prevent the duct section (423) and the motor section (500) or reducer (600) from being exposed to the outside. The rear cover (430) can be positioned apart from the duct section (423) and the driving section (500, 600).

[0164] The above rear cover (430) has the effect of preventing the motor section (500) from being damaged by external interference or from heat loss occurring through the duct section (423) and reducing drying efficiency.

[0165] Figure 4 shows a cross-sectional view of the driving unit.

[0166] The permanent magnet located on the inner surface of the rotor (520) can move in a specific direction due to the rotating magnetic field generated in the stator (510), and the permanent magnet can be fixed to the inner surface of the rotor (520). Therefore, the rotor (520) can rotate due to the rotating magnetic field of the stator (510).

[0167] A drive shaft (530) that rotates together with the rotor (520) and transmits the rotational power of the rotor (520) may be coupled to the rotation center of the rotor (520). The drive shaft (530) may be provided to rotate together with the rotor (540). The drive shaft (530) may be coupled to the rotor (540) through a washer portion (540).

[0168] The above drive shaft (530) may be directly connected to the rotor (520), but when connected through the washer portion (540), it can be more firmly coupled to the rotor (520), thereby transmitting the rotational power of the rotor (520) more effectively. In addition, there is an effect of increasing the durability of the drive shaft (530) by preventing a concentrated load from being applied to the drive shaft (530).

[0169] The above drive shaft (530) may be directly connected to the drum, but since the drive shaft (530) rotates at the same speed as the rotational speed of the rotor (520), there may be cases where deceleration is required. Accordingly, the drive shaft (530) may be connected to a reducer, and the reducer may be connected to the drum. That is, the reducer (600) may reduce the rotation of the drive shaft (530) to rotate the drum (200).

[0170] The above-described reducer (600) may include a first housing (610) forming an exterior, a second housing (620), and a gearbox (630) reducing the power of a drive shaft (530). The second housing (620) provides a space capable of accommodating the gearbox (630), and the first housing (610) may shield the accommodating space provided by the second housing (620).

[0171] The second housing (620) may be composed of a second housing coupling body (621) coupled with the first housing (610), a second housing blocking body (622) extending rearward from the inner surface of the second housing coupling body (621) to form a receiving space and to receive a gear box (630), and a second housing shaft receiving portion (623) extending rearward from the second housing blocking body (622) to receive a driving shaft (530).

[0172] The gearbox (630) may include a ring gear (633) installed along the inner surface of the second housing blocking body (622). One or more planetary gears (632) that are gear-engaged with the ring gear (633) may be provided on the inner surface of the ring gear (633), and a sun gear (631) that is gear-engaged with the planetary gear (632) and rotates together with the drive shaft (530) may be provided on the inner side of the ring gear (633).

[0173] The sun gear (631) may be provided to rotate by being coupled to the drive shaft (530). The sun gear (631) may be provided as a separate member from the drive shaft (530), but is not limited thereto, and the sun gear (631) may be formed integrally with the drive shaft (530).

[0174] The above sun gear (631), planetary gear (632), and ring gear (633) may be provided as helical gears. When each gear is provided as a helical gear, noise can be reduced and power transmission efficiency can be increased. However, the present invention is not limited thereto, and the sun gear (631), planetary gear (632), and ring gear (633) may be provided as spur gears.

[0175] As an example of the operation of the gearbox (630), when the rotor rotates, the drive shaft (530) and the sun gear (631) connected to the drive shaft (530) rotate, and the planetary gear (632) that is gear-engaged on the outer surface of the sun gear (631) can rotate by being gear-engaged between the ring gear (633) and the sun gear (631).

[0176] The above planetary gear (632) may include a planetary gear shaft (6323) inserted into the center of rotation. The planetary gear shaft (6323) may rotatably support the planetary gear (632).

[0177] The above-described reducer may further include a first carrier (6342) and a second carrier (6343) that support the planetary gear shaft (6323). The planetary gear shaft (6323) may be supported at the front by the second carrier (6343) and at the rear by the first carrier (6342).

[0178] The drum rotation shaft (6341) may be provided to extend away from the motor unit from the center of rotation of the second carrier (6343). The drum rotation shaft (6341) may be provided as a separate structure from the second carrier (6343) and may be coupled to rotate together. On the other hand, the drum rotation shaft (6341) may be extended from the second carrier (6343) and formed integrally with the second carrier (6343).

[0179] The drum rotation shaft (6341) can be coupled to the drum to rotate the drum. As described above, the drum rotation shaft (6341) can be coupled to the drum via a connecting member such as a bushing, or can be directly coupled to the drum without a separate connecting member.

[0180] The drum rotation shaft (6341) may be supported by the first housing (610). The first housing (610) may include a first housing blocking body (611) that blocks the receiving space of the second housing (620) and a first housing shaft receiving portion (612) that extends away from the second housing (620) from the first housing blocking body (611) to receive the drum rotation shaft (6341). A first bearing (660) and a second bearing (670) may be press-fitted onto the inner surface of the first housing shaft receiving portion (612) to rotatably support the drum rotation shaft (6341).

[0181] The first housing (610) and the second housing (620) can be coupled to each other through a reducer fastening member (681). In addition, the reducer fastening member (681) can simultaneously penetrate through the first housing (610) and the second housing (620) to couple the two members. In addition, the reducer fastening member (681) can simultaneously penetrate through the first housing (610), the second housing (620), and the rear plate (420) to couple the first housing (610) and the second housing (620) and simultaneously fix the reducer (600) to the rear plate (420).

[0182] The rear plate (420) may be formed of a thin steel plate. Therefore, it may be difficult to secure rigidity to support the reducer (600), the motor unit (500) coupled to the reducer (600), and the drum (200) connected to the reducer (600). Therefore, when the reducer (600) is coupled to the rear plate (420), a bracket (700) may be used to secure the rigidity of the rear plate (420). The bracket (700) may be formed of a material having a higher rigidity than the rear plate (420) and may be coupled to the front or rear of the rear plate (420).

[0183] The above bracket (700) is coupled to the front of the rear plate (420) to secure rigidity to which the reducer (600) can be coupled, and the reducer (600) can be coupled simultaneously with the rear plate (420) and the bracket (700). A fastening member such as a bolt can be used to couple the rear plate (420), the bracket (700), and the reducer.

[0184] In addition, the reducer fastening member (681) used to connect the first housing (610) and the second housing (620) to fix the reducer (600) to the rear plate (420) can be used. That is, the reducer fastening member (681) can penetrate and connect the second housing (620), the first housing, the rear plate (420), and the bracket (700) at once. When connected in this way, the rear plate (420) can be supported by the bracket (700) at the front and by the first housing (610) at the rear, so that rigidity can be secured even by the connection of the reducer (600). However, it is not limited to this, and only the first housing (610) and the second housing (620) can be connected using a reduction gear fastening member (681) first, and then the reduction gear (600) can be connected to the rear plate (420) using a separate fastening member.

[0185] In addition, a stator coupling portion (613) to which a motor portion (500) can be coupled may be formed on the radially outer side of the first housing (610). The stator coupling portion (613) may include a coupling groove formed by recessing the stator coupling portion (613).

[0186] The stator (510) may be directly coupled to the rear plate (420), but may also be coupled to the stator coupling portion (613). The stator (510) may include a fixed rib (512) provided on the inner circumferential surface to support the stator. The fixed rib (512) may be coupled to the stator coupling portion (613). The fixed rib (512) and the stator coupling portion (613) may be coupled to each other by a stator coupling pin (617).

[0187] The above motor unit (500) is coupled to the reducer (600) while being spaced apart from the rear plate (420), so that the motor unit (500) and the reducer (600) can form a single vibrating body. Accordingly, even if vibration is applied from the outside, the drive shaft (530) coupled to the rotor (520) and the drum rotation shaft (6341) connected to the reducer (600) can easily maintain coaxiality.

[0188] The above drum rotation shaft (6341) is at risk of being misaligned due to vibration of the drum (200). However, since the motor unit (500) is coupled to the first housing (610) that supports the drum rotation shaft (6341), even if the axial direction of the drum rotation shaft (6341) is misaligned, the axial direction of the drive shaft (530) will also be similarly misaligned by the first housing (610). That is, the motor unit (500) moves integrally with the reducer (600), so that the drum rotation shaft (6341) and the drive shaft (530) can maintain coaxiality even when force is applied from the outside.

[0189] The efficiency and reliability of the power generated from the motor unit (500) being transmitted to the drum (200) by the above-described coupling structure are increased, and there is an effect of preventing wear of the gearbox (630), reduction in efficiency of power transmission, and reduction in durability and reliability caused by shaft misalignment between the drum rotation shaft (6341) and the drive shaft (530).

[0190] Figure 5 is a perspective view of a base (800) of a garment treatment device according to one embodiment of the present invention.

[0191] The above base (800) may include a circulation path (820) on one side for circulating air in the drum.

[0192] The above circulation path (820) may be provided in the form of a duct that provides a space in which air flows and a heat exchanger (900) is installed. However, the upper surface of the circulation path (820) may be provided to be open so as to facilitate installation and maintenance of the heat exchanger (900).

[0193] The clothing treatment device of the present invention may further include a duct cover part (830) that is coupled to the upper portion of the circulation path part (820) to prevent leakage of air introduced into the circulation path part (820) and to form a path through which the air moves.

[0194] The above duct cover part (830) may be provided in a plate shape that is coupled to the open upper surface of the circulation flow part (820). For example, the upper surface and the back surface of the inlet duct (821) and the upper surface of the moving duct (822) may be provided to be open.

[0195] The above duct cover part (830) can form the back surface of the inflow duct (821) while shielding the open upper surface of the moving duct (822).

[0196] Of course, the above inlet duct (821) may be a square duct or a ring-shaped, completely closed curve, and the duct cover (830) may be provided to shield the upper surface of the moving duct (822).

[0197] Accordingly, the duct cover part (830) can prevent air introduced through the inlet duct (821) from leaking out through the open upper surface of the moving duct (822). The duct cover part (830) can be seen as forming the upper surface of a flow path that guides air introduced through the inlet duct (821) to the exhaust duct (823).

[0198] In addition, the base (800) may be provided with a device installation section (810) that provides a space on the other side where electrical components necessary for the operation of the dryer are installed.

[0199] The above device installation part (810) may be provided on the outside of the above circulation path part (820).

[0200] In a conventional dryer, a circulation path (820) is provided on the base (800), and a driving unit for rotating a drum (200) is also installed on the base (800). In this case, since the driving unit occupies a large portion of the installation space of the base (800), the space of the device installation unit (810) is narrow, making it difficult to install other components of the clothing treatment device. However, in a clothing treatment device according to an embodiment of the present invention, the motor unit (500) for rotating the drum (200) can be placed at the rear of the drum (200) apart from the base (800), so that the space of the base (800) where the motor unit (500) was previously installed can be utilized in various ways.

[0201] For example, the device installation unit (810) may be equipped with a compressor (930) that compresses the refrigerant required for heat exchange, a collection unit (860) that is spaced apart from the compressor (930) and collects condensate generated in the circulation path unit (820), and a steam supply unit (2000) that supplies steam to at least one of the drum (200) and the circulation path unit (820).

[0202] The above collection unit (860) is provided to communicate with the side or bottom surface of the circulation passage unit (820) and can be placed on the device mounting unit (810) outside the circulation passage unit (820).

[0203] The evaporator (910) and the condenser (920) are installed inside the circulation passage (820). Water condensed in the evaporator (910) can be collected on the bottom surface of the circulation passage (820). The condenser (920) heats air passing through the circulation passage (820) to generate hot air. In this case, if water is placed in a state of being collected on the bottom surface of the circulation passage (820), there is a possibility that the water may vaporize due to the heat generated in the condenser (920) and flow back into the drum (200). To prevent this, the water collection unit (860) can be placed outside the circulation passage (820) to collect moisture condensed in the circulation passage (820) from the outside of the circulation passage (820).

[0204] The above collection unit (860) can collect not only the water condensed in the evaporator (910), but also all the water supplied into the circulation path unit (820) or condensed in the circulation path unit (820).

[0205] The clothing treatment device of the present invention may further include a drainage pump (861) capable of discharging water collected in the water collection unit (860) to the outside of the water collection unit (860).

[0206] The above drainage pump (861) is installed in the water collection unit (860) and can generate power to discharge water collected in the water collection unit (860) to the outside of the water collection unit (860).

[0207] The above drainage pump (861) may be provided to discharge water collected in the water collection unit (860) into the water storage tank (120) or a sewer. Thus, even if the water collection unit (860) reaches full water level, the water collection unit (860) is emptied and can continuously collect new condensate. As a result, water remaining inside the circulation flow unit (820) can be minimized.

[0208] The above water collection unit (860) can be arranged to overlap the compressor (930) in the front-rear direction. This allows the volume of the water collection unit (860) to be further expanded, allowing a larger amount of water to be collected.

[0209] As the volume of the water collecting unit (860) is expanded in this way, the frequency of emptying the condensate collected in the water collecting unit (860) can also be reduced, and even if new water such as direct water is supplied to the circulation flow unit (820) in addition to the condensate, it can all be collected without leakage.

[0210] Meanwhile, even if a filter unit for filtering foreign substances is arranged in the duct connection unit (416), the air discharged from the drum (200) and circulating through the circulation path unit (820) contains foreign substances such as lint discharged from clothing. The evaporator (910) is configured to come into contact with the air discharged from the drum (200) before the condenser (920), and since the thin plates are closely stacked to exchange heat with the air, foreign substances such as lint are likely to accumulate in the evaporator (910).

[0211] In addition, the circulation flow path (820) may further include a duct filter (not shown) provided in front of the evaporator (910) to filter foreign substances in the air passing through the inlet duct (821).

[0212] The above filter part is provided so that it can be withdrawn from the duct connection part (416) to remove filtered foreign substances, but the duct filter is positioned so that it is not exposed to the outside until the worker opens the circulation path part (820).

[0213] Therefore, filtered foreign substances may accumulate in the duct filter.

[0214] In addition, since the duct filter cannot filter all foreign substances, foreign substances that pass through the duct filter may also accumulate in the evaporator (910).

[0215] If foreign substances accumulate in the evaporator (910) or duct filter, not only will the air flow in the circulation passage (820) be obstructed, but the foreign substances may also retain moisture, lowering the coefficient of performance (COP) of the heat exchanger (900), and even causing the foreign substances to rot. Therefore, it is necessary to periodically remove foreign substances accumulated in the evaporator (910) or duct filter, etc.

[0216] To this end, the clothing treatment device of the present invention may further include a direct water washing unit (1000) that can directly receive water supplied from an external water source and remove foreign substances accumulated in at least one of the evaporator (910) or the duct filter.

[0217] The external water source may be configured to be located outside the cabinet (100) and supply water to the interior of the cabinet (100), and may correspond to, for example, a faucet located outside the cabinet (100). Since the direct water washing unit (1000) is supplied with clean water free of foreign substances, the circulation flow unit (820) can always be washed with clean water.

[0218] Water supplied from the above-mentioned direct washing unit (1000) and injected into the circulation path unit (820) can be discharged from the circulation path unit (820) to the water collection unit (860). The water collected in the water collection unit (860) can be discharged to the water storage tank (120) and discarded, or can be discharged directly to an external sewer and discarded.

[0219] The garment treatment device of the present invention may further include a steam supply unit (2000) that supplies steam to at least one of the drum (200) and the circulation path unit (820).

[0220] The above steam supply unit (2000) may be equipped to receive water from an external water source and heat it to generate steam.

[0221] The above steam supply unit (2000) may be provided so that water can be supplied from an external water source separately from the direct water washing unit (1000). Alternatively, to simplify the design of the flow path, the steam supply unit (2000) may be provided so that water is supplied through communication with the direct water washing unit (1000).

[0222] The steam supply unit (2000) may be positioned in front of the water collection unit (860). This makes it easy to not only mount the steam supply unit (2000) on the base (800), but also to maintain and repair it.

[0223] The steam mounting portion (890) may be provided in front of the water collecting portion (860) so that the steam supply portion (2000) can be installed thereon. The steam mounting portion (890) may be spaced apart from the front of the water collecting portion (860) and may be positioned offset from either side of the base (800).

[0224] The above steam supply unit (2000) can be detachably provided on the upper portion of the steam mounting unit (890), and the steam mounting unit (890) can be formed to accommodate at least a portion of the steam supply unit (2000).

[0225] Figure 6 illustrates the detailed structure of the base.

[0226] The above-described direct water washing unit (1000) may be provided to supply water to the upstream of the above-described circulation path unit (820). Thus, the above-described direct water washing unit (1000) may remove foreign substances accumulated on at least one of the evaporator (910), the duct filter, and the bottom surface of the above-described circulation path unit (820) using water. The foreign substances removed together with the water may be collected in the water collecting unit (860) and discharged to the water storage tank (120) or a sewer.

[0227] Hereinafter, washing the evaporator (910), washing the duct filter, or washing the inside of the circulation passage (820) with water are collectively referred to as washing the evaporator (910). That is, washing the evaporator (910) can be defined as a concept that includes washing not only the evaporator (910), but also at least one of the duct filter and the circulation passage (820).

[0228] The above-mentioned direct water washing unit (1000) may include a direct water valve (1100) that is connected to an external water source to receive water, a direct water nozzle (1300) that supplies water supplied from the direct water valve (1100) into the inside of the circulation path (820), and a direct water pipe (1200) that connects the direct water valve (1100) and the direct water nozzle (1300) to guide water.

[0229] The above direct water valve (1100) can be controlled to selectively connect the direct water pipe (1200) to an external water source.

[0230] The above-mentioned direct valve (1100) may be positioned closer to the rear than the front of the base (800). The above-mentioned direct valve (1100) may be fixed to the rear panel or to the base (800).

[0231] The above-mentioned direct valve (1100) may be placed in the device installation section (810). For example, the above-mentioned direct valve (1100) may be placed outside the above-mentioned circulation path section (820) and may be placed between the above-mentioned circulation path section (820) and the above-mentioned compressor (930).

[0232] The above base (800) may further include a fixing bracket (880) that fixes the direct valve (1100) to the device installation part (810).

[0233] The above-mentioned fixed bracket (880) may be provided integrally with the base (800), or may be provided separately from the base (800) and fixed by being coupled to the base (800). When the above-mentioned fixed bracket (880) is provided separately from the base (800), the above-mentioned fixed bracket (880) may be provided with a metal material. Accordingly, the above-mentioned direct water valve (1100) can be stably supported not only under the load of the direct water valve (1100), but also when high-pressure water is supplied to the direct water valve (1100).

[0234] The above fixed bracket (880) may protrude upward from the rear of the device installation part (810). The above fixed bracket (880) may be provided in a plate shape.

[0235] The above-mentioned direct valve (1100) can be positioned spaced upward from the base (800) by being coupled to the above-mentioned fixed bracket (880). This can prevent the direct valve (1100) from being damaged by vibration transmitted to the base (800).

[0236] Meanwhile, the direct water valve (1100) may be positioned at a position lower than the upper height of the circulation path (820). That is, at least a portion of the direct water valve (1100) may be positioned lower than the duct cover (830), and the entire direct water valve (1100) may be positioned lower than the duct cover (830). As a result, the direct water valve (1100) and the direct water pipe (1200) may be prevented from interfering with the rotating drum (200).

[0237] The above direct water valve (1100) may include a main valve (1110) connected to an external water source, and a supply valve (1120) connected from the main valve (1100) to selectively supply water to the direct water pipe (1200).

[0238] The above main valve (1110) can be controlled so that water supplied from an external water source can be selectively introduced into the cabinet (100). In addition, the above supply valve (1120) can be controlled so that water passing through the main valve (1110) can be selectively supplied to the direct water pipe (1200).

[0239] As a result, water can be supplied from the external water source to the direct water nozzle (1300) only when the main valve (1100) and the supply valve (1120) are fully opened, and water can be prevented from randomly flowing out even if either the main valve (1100) or the supply valve (1120) is damaged.

[0240] The above-mentioned straight pipe (1200) may be provided so that one end is connected to the supply valve (1120) and the other end is connected to the straight nozzle (1300). The above-mentioned straight pipe (1200) may be provided with an elastic material. For example, the above-mentioned straight pipe (1200) may be provided with a rubber hose or the like.

[0241] The above-mentioned direct water nozzle (1300) may be provided to receive water from the direct water pipe (1200) and discharge the water into the circulation path (820).

[0242] The above-mentioned direct water nozzle (1300) may be positioned above the above-mentioned evaporator (910). In addition, the above-mentioned direct water nozzle (1300) may be provided in a case shape that can temporarily store water supplied from the direct water pipe (1200). Thus, the direct water nozzle (1300) can secure the maximum water pressure and quantity to remove foreign substances attached to the heat exchange unit (900).

[0243] The above-described straight nozzle (1300) may be provided in a rod shape in which the width in the left-right direction is longer than the width in the front-back direction. The width of the straight nozzle (1300) may be provided to be equal to or greater than the width of the evaporator (910). In addition, the straight nozzle (1300) may be arranged closer to the front area than the rear area of ​​the evaporator (910). The straight nozzle (1300) may be arranged so that at least a portion overlaps the front area of ​​the evaporator (910). As a result, the entire front area of ​​the evaporator (910) can be cleaned.

[0244] Meanwhile, the direct water nozzle (1300) may be configured to supply water by segmenting the evaporator area. Thus, even if the amount and pressure of water supplied from the direct water valve (1100) are set low, water can be sequentially and intensively supplied to certain sections of the evaporator, thereby removing any attached foreign substances without issue.

[0245] Unlike the drawing, the direct nozzle (1300) may be provided in multiple numbers and arranged in the width direction of the evaporator (910).

[0246] That is, as long as the above-mentioned direct nozzle (1300) is arranged in the width direction of the evaporator (910) and can supply water to the front of the evaporator (910), it may be provided in any shape or number.

[0247] In the following, the above-described direct nozzle (1300) is described based on an embodiment in which the interior is partitioned, but the description can also be applied to an embodiment in which a plurality of direct nozzles (1300) are provided.

[0248] The above-mentioned direct water valve (1100) is provided in multiple numbers, and can be controlled to selectively supply water to a partitioned area of ​​the direct water nozzle (1300).

[0249] Alternatively, the supply valve (1120) may be provided in multiple units so as to selectively supply water to a partitioned area of ​​the direct water nozzle (1300). As a result, the direct water valve (1100) may be provided in one unit, facilitating installation and maintenance, and reducing the space occupied by the direct water valve (1100) within the cabinet (100).

[0250] The above supply valve (1120) may be provided in a number corresponding to the area where the direct nozzle (1300) is partitioned.

[0251] For example, when the direct nozzle (1300) is divided into two areas, the intermediate supply valve (1120) may include a first supply valve (1121) that selectively passes water supplied from the main valve (1100), and a second supply valve (1122) that is independently controlled from the first supply valve (1121) and selectively passes water supplied from the main valve (1100).

[0252] The above first supply valve (1121) and the above second supply valve (1122) may be arranged in combination with each other as long as the internal flow path is partitioned and water can be selectively supplied.

[0253] The above steam supply unit (2000) may be equipped to receive water from the direct water valve (1100).

[0254] The above steam supply unit (2000) may include a steam case (2100) installed in the steam mounting unit (860) to store water, a steam pipe (2200) connecting the direct water valve (1100) and the steam case (2100), a steam nozzle (2300) supplying steam generated in the steam case (2100) to the inside of the drum (200) or the circulation path (820), and a moving pipe (2400) connecting the steam case (2100) and the steam nozzle (2300).

[0255] The above steam supply unit (2000) may include a steam heater that generates steam by heating water stored inside the steam case (2100), and a plurality of sensors that can detect the water level and temperature in the steam case (2100).

[0256] The above steam pipe (2200) may be provided so that one end is connected to the direct water valve (1100) and the other end is connected to the steam case (2100) to allow water to move.

[0257] The above direct water valve (1100) may be provided to supply water to both the direct water nozzle (1300) and the steam case (2100). As a result, a separate direct water valve for supplying water to the steam case (2100) may be omitted.

[0258] The above direct valve (1100) may further include a steam valve (1130) that selectively guides water supplied from the main valve (1110) to the steam case (2100).

[0259] The above steam valve (1130) can be arranged in connection with the supply valve (1120) and can be controlled independently of the supply valve (1120).

[0260] The above steam valve (1130) can be placed at the end of the above direct water valve (1100).

[0261] The above direct water valve (1100) may be provided so that when the main valve (1110) is opened, water supplied from an external water source reaches both the supply valve (1120) and the steam valve (1130).

[0262] When both the supply valve (1120) and the steam valve (1130) are controlled to open, water supplied from the main valve (1100) can be supplied to both the direct nozzle (1300) and the steam case (2100).

[0263] In addition, the direct water valve (1100) may be provided so that when the main valve (1110) is opened and water supplied to an external water source is supplied only through the open valve when only one of the supply valve (1120) and the steam valve (1130) is opened.

[0264] When the supply valve (1120) is controlled to open and the steam valve (1130) is controlled to close, water can be supplied to the direct water valve (1300) and the water supply to the steam case (2100) can be closed. In addition, when the supply valve (1120) is controlled to close and the steam valve (1130) is controlled to open, the water supply to the direct water valve (1300) can be closed and water can be supplied to the steam case (2100).

[0265] The above steam pipe (2200) may be positioned closer to the upper part of the steam case (2100) than to the lower part. This prevents the water contained in the steam case (2100) from flowing back.

[0266] The above moving pipe (2400) can have one end coupled to the steam case (2100) and the other end coupled to the steam nozzle (2300).

[0267] The above moving pipe (2400) may be positioned closer to the upper portion than the lower portion of the steam case (2100). Thus, when steam having a specific gravity lighter than water is generated, it can be automatically discharged to the steam nozzle (2300) along the moving pipe (2400).

[0268] The above moving pipe (2400) can be placed apart from the above steam pipe (2200).

[0269] The garment treatment device of the present invention may further include an additional valve for opening and closing the moving pipe (2400). This allows the steam generated in the steam case (2100) to be controlled to be supplied to the steam nozzle (2300).

[0270] However, the clothing treatment device of the present invention can be equipped so that the steam generated in the steam case (2100) can automatically move to the moving pipe (2400) and the steam pipe (2200) by omitting a separate valve for opening and closing the moving pipe (2400).

[0271] If the steam pipe (2200) is closed at the end by the steam valve (1130), the steam generated in the steam case (2100) can be automatically discharged only through the moving pipe (2400).

[0272] Meanwhile, the moving pipe (2400) may be provided with a diameter greater than that of the steam pipe (2200) and with a greater resistance to flow. The moving pipe (2400) may be provided with a length greater than that of the steam pipe (2200) or with a diameter smaller than that of the steam pipe (2200).

[0273] Accordingly, the steam generated in the steam case (2100) can be induced to be discharged preferentially through the steam pipe (2200) rather than through the moving pipe (2400).

[0274] Accordingly, if the steam valve (1130) is open and the supply valve (1120) is also open, the steam generated in the steam case (2100) moves along the steam pipe (2200) and is supplied to the direct nozzle (1300), but may not be discharged through the moving pipe (2400).

[0275] However, if the steam valve (1130) is closed, or if the steam valve (1130) is open but the supply valve (1120) is closed, the steam can be discharged through the transfer pipe (2400).

[0276] Accordingly, even if there is no device to separately open and close the above-mentioned moving pipe (2400), the steam can be selectively moved to the moving pipe (2400) according to the control of the above-mentioned direct valve (1100).

[0277] The above steam nozzle (2300) can be placed inside the gasket (413) of the front plate (410). Thus, the steam supplied from the steam nozzle (2300) can be directly injected into the drum body (210).

[0278] As illustrated, the steam nozzle (2300) may be placed in the circulation path (820). In this case, the steam sprayed from the steam nozzle (2300) may be supplied preferentially to the circulation path (820) and then supplied together with hot air to the back surface of the drum body (210) by the operation of the circulation path fan (950).

[0279] The above steam nozzle (2300) may be placed in front of the above evaporator (910).

[0280] The above steam nozzle (2300) can be spaced apart from the direct nozzle (1300) and fixed to the duct cover part (830).

[0281] Accordingly, the steam sprayed from the steam nozzle (2300) can sterilize the evaporator (910).

[0282] Meanwhile, when the steam generator (2000) is controlled so that steam is supplied from the steam nozzle (2300), the compressor (930) can be blocked from operation to prevent the steam passing through the evaporator (910) from being cooled. As a result, the steam can be injected into the drum (200) at a high temperature while also sterilizing the evaporator (910).

[0283] When the compressor (930) is driven, the steam generator (2000) can be controlled so that steam is supplied from the steam nozzle (2300) at least in some sections. As a result, the refrigerant passing through the evaporator (910) can more easily absorb heat, thereby increasing the temperature and pressure of the refrigerant fed into the compressor (930), thereby improving the coefficient of performance (COP) of the heat pump system.

[0284] For example, if steam is controlled to be sprayed from the steam nozzle (2300) at the beginning of the drying process, the time it takes for the compressor (930) to accelerate to the target speed can be shortened.

[0285] Figure 7 illustrates the flow path relationship between the water collection unit, the direct washing unit (1000), and the steam generation unit.

[0286] Fig. 7(a) shows a perspective view of the base (800), and Fig. 7(b) shows a view of the base (800) viewed from above.

[0287] The above water collection unit (860) may include a water collection body (862) that forms a space where condensate is collected, a water collection cover (863) that shields the open upper surface of the water collection body (862), and a drainage pump (861) that discharges water collected in the water collection body (862).

[0288] The above-mentioned water collecting body (862) may be installed in the device installation section (810) and may be arranged on one side of the circulation path section (820). In addition, the water collecting body (862) may be arranged closer to the evaporator (910) than to the condenser (920). For example, the water collecting body (862) may be arranged on one side of the evaporator (910).

[0289] Additionally, the water collection body (862) may be arranged so that at least a portion of the water collection body (1300) overlaps with the water collection nozzle (1300) in the left-right direction.

[0290] Accordingly, the water condensed in the evaporator (910) and the water supplied to the direct nozzle (1300) can be directly discharged to the water collection unit (860) while minimizing the time or area in which the water remains in the circulation path (820). As a result, the water remaining in the circulation path (820) is minimized, so that the cleanliness of the circulation path (820) can be maintained, and the water can be prevented from evaporating again and being reintroduced into the drum (200).

[0291] The above water collecting body (862) may be positioned in front of the compressor (930) and behind the steam generating unit (800). The above water collecting body (862) may be positioned below the direct water washing unit (1000) and in front of the direct water valve (1100).

[0292] The above water collection cover (863) is coupled to the water collection body (862) to prevent condensate from leaking to the upper surface of the water collection body (862) and to maintain the negative pressure at which the drain pump (861) discharges the water.

[0293] The above water collection cover (863) may have an area in the center where the drainage pump (861) is installed.

[0294] The above water collection unit (860) may further include a drain pipe (864) that guides water discharged from the drain pump (861) to the water storage tank (120) or a sewer.

[0295] The above drain pipe (864) is connected at one end to the drain pump (861) so that water collected in the water collecting body (862) can be discharged outside the water collecting unit (860).

[0296] The end of the above drain pipe (864) may be directly connected to the water storage tank (120) or may extend toward a sewer.

[0297] However, the base (800) may further include a discharge portion (865) to which the end of the drain pipe (864) is connected. The discharge portion (865) may be provided integrally with the base (800) or may be separately connected and arranged at the rear of the device installation portion (860). The discharge portion (865) may have the front side connected to the drain pipe (864) and the back side connected to a separate drain pipe. The drain pipe may be connected to a drain located outside the cabinet or connected to a water storage tank (120). Accordingly, the location where water drained from the drain pipe (864) is discharged is determined depending on the installation location of the drain pipe outside the discharge portion (865), and the installation location of the drain pipe (864) can always be fixed in the base (800).

[0298] The above drain pipe (864) can be arranged so as to be completely separated from the direct water washing unit (1000) and the steam supply unit (2000). This can prevent water collected in the water collection unit (860) from being re-introduced into the direct water nozzle (1300) or the steam case (2100).

[0299] The height of the above fixed bracket (880) can be positioned higher than the height of the discharge portion (865). As a result, the direct water valve (1100) and the direct water pipe (1200) can be positioned higher than the discharge portion (865).

[0300] The above drain pipe (864) may be arranged so that at least a portion thereof is higher than the straight pipe (1200). For example, the drain pipe (864) may be supported on the upper portion of the straight pipe (1200). Both ends of the drain pipe (864) may be arranged lower than a central region that is arranged higher than the straight pipe (1200). As a result, even if the operation of the drain pump (861) is stopped, water may not remain in the drain pipe (864) but may be discharged to the discharge portion (865) or remain in the drain pump (861).

[0301] The above steam pipe (2200) may be positioned lower than the above straight pipe (1200). At least a portion of the above steam pipe (2200) may be fixed to the side of the circulation path (820) or supported on the upper surface of the device installation part (810).

[0302] By inducing water to remain inside the steam pipe (2200), steam generated in the steam supply unit (2000) can be prevented from flowing back into the steam pipe (2200).

[0303] The above moving pipe (2400) can be placed at a height corresponding to the above straight pipe (1200).

[0304] The above-mentioned moving pipe (2400) may have one end coupled to the front of the steam case (2100) and the other end coupled to one end of the steam nozzle (1300). The moving pipe (2400) may extend from the steam case (2100) toward the steam nozzle (1300) while maintaining its height or increasing its height. As a result, steam may be induced to move toward the steam nozzle (1300), and water condensed in the moving pipe (2400) may be recovered to the steam case (2100).

[0305] Figure 8 illustrates the arrangement relationship between the steam nozzle (2300) and the direct water nozzle (1300).

[0306] The above direct nozzle (1300) may be placed on the upper portion of the evaporator (910) and may be placed closer to the front surface than the rear surface of the evaporator (910).

[0307] The above direct nozzle (1300) is arranged so that at least a portion overlaps the front of the evaporator (910), and the remainder may be arranged in front of the evaporator (910).

[0308] The above-mentioned direct water nozzle (1300) may include a direct water body (1310) through which water supplied from a direct water pipe (1200) moves, a connecting pipe (1320) provided at one end of the direct water body (1310) and connected to the direct water pipe (1200), and a nozzle part (1330) provided at the lower part of the direct water body (1310) and discharging water.

[0309] The above nozzle part (1330) can be placed at the front upper portion of the above evaporator (910).

[0310] Accordingly, the water supplied from the nozzle unit (1330) accumulates in front of the evaporator (910) and can directly collide with foreign substances.

[0311] The above steam nozzle (2300) may be placed upstream of the above direct water nozzle (1300).

[0312] The above steam nozzle (2300) may be positioned further forward than the direct water nozzle (1300) and may be positioned further forward than the evaporator (910).

[0313] The above steam nozzle (2300) may include a steam body (2310) that guides steam supplied from the moving pipe (2400) in the width direction of the evaporator (910) or the moving duct (822), an inlet pipe (2320) provided at one end of the steam body (2310) and connected to the moving pipe (2400), and an injection part (2330) that discharges steam to the lower portion of the steam body (2310).

[0314] The above steam body (2310) may be provided with a width in the left-right direction longer than the width in the front-back direction and may be provided in a rod shape.

[0315] The above injection unit (2330) may be provided to penetrate the lower part of the steam body (2310) or to extend downward from the steam body (2310) so that steam can be discharged to the lower part of the steam body (2310).

[0316] The above-mentioned injection unit (2330) may be arranged to be inclined backward from the steam body (2310) so that steam can be injected toward the evaporator (910). The injection unit (2330) may extend inclinedly from the lower portion of the steam body (2310) toward the evaporator (910).

[0317] The above injection unit (2330) may be provided in the shape of a slit in the width direction, or may be provided in the shape of a pipe extending from the steam body (2310).

[0318] Accordingly, the steam sprayed from the steam nozzle (2300) can be supplied to the front of the evaporator (910) to sterilize the evaporator (910). In addition, the steam sprayed from the steam nozzle (2300) is prevented from being directly exposed to the bottom surface of the moving duct (822), etc., thereby preventing the steam from condensing inside the circulation path (820).

[0319] The above injection unit (2330) can be placed at the center of the width of the evaporator (910).

[0320] Figure 9 illustrates the appearance of a direct nozzle (1300) connected to a direct pipe (1200).

[0321] The above-described direct water nozzle (1300) is internally partitioned and can supply water by dividing the area inside the circulation path (820). In addition, the direct water pipe (1200) and the supply valve (1120) that supplies water to the direct water pipe (1200) are provided in multiple numbers to correspond to each partitioned area of ​​the direct water nozzle (1300) and can supply water to each area of ​​the direct water nozzle (1300).

[0322] In one embodiment of the present invention, as shown in FIG. 9, the direct water nozzle (1300) is divided into a first nozzle area (1310) and a second nozzle area (1320), and water can be supplied from a first direct water pipe (1210) connected to a first supply valve (1121) and a second direct water pipe (1320) connected to a second supply valve (1122), respectively.

[0323] The above control unit (190) is provided to individually control a plurality of the supply valves (1120), and can supply water to the first nozzle area (1310) and the second nozzle area (1320) by alternately opening the first supply valve (1121) and the second supply valve (1122).

[0324] Accordingly, even if the water supplied from the external water source to the direct water valve (1100) is not enough to clean the entire area of ​​the direct water nozzle (1300) upstream of the first heat exchanger (910) or the front of the duct filter, the efficiency of heat exchange can be increased by supplying water only to the area requiring cleaning.

[0325] In one embodiment of the present invention, the circulation path (820) may be arranged to be biased toward one side of the drum (200) so as to avoid the lowest end of the drum (200) as much as possible and may be provided to extend along the front-back direction of the drum (200).

[0326] In this case, the direct nozzle (1300) may be arranged to cross the direction in which air flows in the drum (200) within the circulation path (820) so as to discharge water across the entire width of the circulation path (820).

[0327] Accordingly, the entire front surface of the first heat exchanger (910) or the front surface of the duct filter can be cleaned.

[0328] In the case described above, considering the optimal arrangement of each component in the base (800), the direct washing unit (1000) can be arranged on the other side of the lateral direction of the drum (200).

[0329] In this case, the air inside the drum (200) may flow toward one side within the circulation passage (820) due to inertia. Accordingly, the density of the air flowing toward one side of the first heat exchanger or / and the duct filter increases, and foreign substances such as dust may accumulate in a biased manner toward one side.

[0330] Accordingly, each area of ​​the direct nozzle (1300) is partitioned along the width direction of the circulation path (820), and may be provided to discharge more water, discharge water for a longer period of time, or discharge water more strongly on one side than on the other side.

[0331] That is, the second supply valve (1122) that supplies water to the second nozzle area (1320) arranged on one side may be provided to be open for a longer time, supply more water, or supply water more strongly than the first supply valve (1121) that supplies water to the first nozzle area (1310) arranged on the other side.

[0332] Even if the above circulation path (820) is not arranged to be biased to one side, when water flows to the second nozzle area (1320) that is relatively far from the direct water washing section (1000), the decrease in the speed of the water transmitted due to the resistance of the direct water nozzle (1300) will be relatively large, so it would be preferable to provide the second direct water pipe (1220) with a smaller flow resistance or to provide water more strongly.

[0333] The above-mentioned direct washing unit (1000) is provided outside the above-mentioned circulation path unit (820), and when the relative positional relationship between the above-mentioned direct washing unit (1000) and the above-mentioned circulation path unit (820) is defined as a first direction and a second direction opposite to the first direction, respectively, the water of the above-mentioned direct washing unit (1000) will flow from the first direction to the second direction and be discharged to the above-mentioned circulation path unit (820).

[0334] In this case, depending on conditions such as the water movement speed in the direct nozzle (1300), a difference may occur in the flow rate discharged to the first direction side and the second direction side of the direct nozzle (1300).

[0335] For example, when water flows from the first direction to the second direction through the direct nozzle (1300), if the flow rate is excessive, the water flows at a high speed to the wall of the end in the second direction, collides with the wall of the end in the second direction, the flow rate decreases, and the water flows from the second direction to the first direction again and is discharged, so the amount of water discharged toward the second direction may be greater than the amount of water discharged toward the first direction.

[0336] In addition, conversely, if the speed of water flowing into the direct nozzle (1300) is relatively low, water is discharged while moving from the first direction to the second direction, so more water can be discharged on the first direction side than on the second direction side.

[0337] In order to resolve the above-described unbalanced water discharge, the direct nozzle (1300) may include a channel for flowing the water from the first direction to the second direction, and a channel in which the wall of the end of the second direction is extended to flow the water transferred in the second direction to the first direction.

[0338] Accordingly, the water flowing through the direct nozzle (1300) is induced to flow alternately in the second direction and the first direction, thereby resolving the imbalance in the amount of water discharged through the first direction and the second direction.

[0339] The structure for resolving the above-described imbalance is not limited to the following, but can be adjusted by the area or number of outlets (not shown) that are provided to penetrate the direct nozzle (1300) and communicate with the circulation path (820).

[0340] Figure 10 is a schematic diagram showing the direct washing unit (1000) discharging water into the circulation path unit (820).

[0341] As described above, the direct water valve (1100) may include a main valve (1110) connected to an external water source, a supply valve (1120) connected to the main valve (1110) to control water supplied to the direct water pipe (1200), and a steam valve (1130) connected to the main valve (1110) to control water supplied to the steam pipe (2200).

[0342] The above control unit (190) can control the main valve (1110), the supply valve (1120), and the steam valve (1130) to be opened and closed independently.

[0343] The above control unit (190) can open the main valve (1110) and the supply valve (1120) and close the steam valve (1130) to allow water supplied from an external water source to flow through the supply valve (1120) to the direct water nozzle (1300).

[0344] The above control unit can alternately open the supply valves (1120) while the main valve (1110) is open and the steam valve (1130) is closed to alternately supply water to each partitioned area of ​​the direct water nozzle (1300).

[0345] As described above in Fig. 9, when the circulation path (820) is disposed relatively to one side in relation to the drum (200), the second supply valve (1122) that opens the second direct water pipe (1220) connected to the second nozzle area (1320) disposed in the one direction is first opened to supply more water in the one direction for washing, thereby maximizing the washing efficiency from limited water resources. Alternatively, the time for which the second supply valve (1122) is opened may be set to be greater than the time for which the first supply valve (1121) that opens the first direct water pipe (1210) connected to the first nozzle area (1310) disposed in the other direction opposite to the one direction is opened.

[0346] As described above in Fig. 9, when the positions of the circulation path (820) and the direct washing part (1000) are relatively defined, the direct washing part (1000) may be arranged in a first direction and the circulation path (820) may be arranged in a second direction opposite to the first direction.

[0347] In this case, the distance for water to move from the partitioned area of ​​the direct nozzle (1300) to the second nozzle area (1320) arranged in the second direction will be set to be relatively long, so that more water is supplied to the second nozzle area (1320) than to the first nozzle area (1310) arranged closer to the first direction. The opening time of the second supply valve (1122) supplying water to the second nozzle area (1320) may be set to be longer than the opening time of the first supply valve (1121) supplying water to the first nozzle area (1310). Alternatively, the second supply valve (1122) may be opened first to maximize the washing efficiency with limited water resources.

[0348] When water is discharged into the circulation path (820) through the direct nozzle (1300), the circulation path fan (950) can be controlled to operate. Accordingly, air flow is induced inside the circulation path (820), and the circulation path fan (950) causes air to flow in a downstream direction so that the inside of the circulation path (1300) corresponds to a negative pressure condition, so that water can be smoothly discharged from the direct nozzle (1300) into the circulation path (1300).

[0349] Figure 11 illustrates steam generated from the steam generator (2000) being discharged through the direct nozzle (1300).

[0350] As described above in FIG. 10, the control unit (190) opens the main valve (1110) and the supply valve (1120) and closes the steam valve (1130) to discharge water through the direct water nozzle (1300) into the circulation path (820), and when a preset time has elapsed, the control unit (190) closes the main valve (1110) and opens the supply valve (1120) and the steam valve (1130) to connect the direct water nozzle (1300) and the steam case (2100).

[0351] In this case, the steam generated in the steam case (2100) can be moved to the steam pipe (2200) and discharged to the circulation path (820) through the direct nozzle (1300). Therefore, the residual water inside the direct nozzle (1300) can be discharged together with the circulation path (820) due to the pressure of the steam.

[0352] The above steam pipe (2200) may be provided so as to be connected to a place higher than the maximum water level that can be accommodated inside the steam case (2100) so that the water accommodated inside the steam case (2100) does not move along the steam pipe (2200).

[0353] Steam is discharged to the circulation path (820) through the direct water nozzle (1300), so that not only is residual water inside the direct water nozzle (1300) removed, but also high-temperature steam passes through the direct water nozzle (1300) to generate a sterilizing effect. Accordingly, residual water retention and bacterial growth inside the direct water nozzle (1300) can be prevented, and problems such as clogging of the direct water nozzle due to lime deposits can be resolved.

[0354] In addition, since a separate structure for removing residual water inside the direct nozzle (1300) is not required, material costs can be reduced and productivity can be improved.

[0355] It can provide power to move inside the steam case (2100).

[0356] When the control unit (190) closes the main valve (1110) and opens the supply valve (1120) and the steam valve (1130), the steam inside the steam case (2100) does not flow into the moving pipe but can be discharged into the circulation path (820) through the direct nozzle (1300).

[0357] In this case, the moving valve (not shown) that controls the steam flowing from the moving pipe (2400) to the steam nozzle (2300) may be blocked so that the steam flows to the steam pipe (2200).

[0358] If a separate moving valve is not provided, the resistance of the moving pipe (2400) is provided to be greater than that of the steam pipe (2200), so that steam can flow preferentially to the steam pipe (2200).

[0359] As shown in Fig. 11, when the main valve (1110) is blocked and the supply valve (1120) and the steam valve (1130) are opened to form a flow between the direct water pipe (1200) and the steam pipe (2200), the circulation fan (950) can be controlled to operate.

[0360] Accordingly, air flow is induced within the circulation path (820), and the circulation path fan (950) causes the air to flow in a downward direction so that the inside of the circulation path (820) corresponds to a negative pressure condition, thereby guiding water to be smoothly discharged from the direct water nozzle (1300) into the circulation path (820). In addition, due to the pressure of the steam flowing in from the steam pipe (2200), movement to the circulation path (820) is promoted, so that residual water remaining in the direct water nozzle (1300) is smoothly removed, thereby increasing heat exchange efficiency from a sanitary and long-term perspective.

[0361] As described above, the direct nozzle (1300) may include a first direction flow path extending in a first direction, and a second direction flow path extending from an end of the first direction flow path and guiding in a second direction different from the first direction.

[0362] In this case, when water from the external water source is discharged to the circulation flow path (820), the water inside the direct water nozzle (1300) flows to the second direction flow path through the first direction flow path, and when the water inside the direct water nozzle (1300) is discharged to the circulation flow path (820) due to the pressure of the steam flowing in from the steam pipe (2200), it can also flow to the second direction flow path through the first direction flow path.

[0363] When water flows from the first direction to the second direction through the above-mentioned direct nozzle (1300), if the flow rate is excessive, the water flows at a high speed to the wall of the end in the second direction, collides with the wall of the end in the second direction, the flow rate decreases, and the water flows from the second direction to the first direction again and is discharged, so the amount of water discharged toward the second direction may be greater than the amount of water discharged toward the first direction.

[0364] In addition, conversely, if the speed of water flowing into the direct nozzle (1300) is relatively low, water is discharged while moving from the first direction to the second direction, so more water can be discharged on the first direction side than on the second direction side.

[0365] Accordingly, since the water inside the direct nozzle (1300) flows through the first directional flow path to the second directional flow path, the above-described unbalanced water discharge can be resolved. FIGS. 12 and 13 illustrate a control flow chart for discharging water remaining in the direct nozzle (1300).

[0366] The above control method may include a drying step (S10) of operating the heat exchange unit (900) to provide high-temperature dry air inside the drum (200). In the drying step (S10), the circulation fan (950) may be operated to form a flow inside the circulation flow unit (820).

[0367] After the above drying step (S10) is initiated, the above

[0368] A cleaning step (S20) may be performed to wash away foreign substances accumulated in the direction in which air flows into the first heat exchanger (910) or in the duct filter by discharging water into the inside of the circulation passage (820).

[0369] In the above washing step (S20), the main valve (1110) and the supply valve (1120) are open and the steam valve (1130) is closed, so that water introduced from an external water source can flow to the direct water nozzle (1300) through the main valve (110) and the supply valve (1120).

[0370] In the above washing step (S20), the supply valves (1120) may be provided to alternately open and alternately supply water to the partitioned area of ​​the direct water nozzle (1300).

[0371] In the above washing step (S20), the circulation fan (950) is controlled to operate to generate air flow inside the circulation path section (820) and maintain negative pressure so that water can be smoothly discharged from the direct water nozzle (1300) into the circulation path section (820).

[0372] After the above washing step (S20) is completed, a residual water discharge step (S30) may be performed in which steam generated in the steam supply unit (2000) is discharged into the circulation path unit (820) through the direct water nozzle (1300).

[0373] In the above residual water discharge step (S30), the control unit (190) blocks the main valve (1110) and opens the supply valve (1120) and the steam valve (1130), thereby connecting the direct water pipe (1200) and the steam pipe (2200).

[0374] In the above residual water discharge step (S30), the moving valve can be blocked to prevent steam from moving to the steam nozzle (2400), etc.

[0375] In the above residual water discharge step (S30), the circulation fan (950) is controlled to operate to generate air flow inside the circulation passage (820) and maintain negative pressure so that water is smoothly discharged from the direct water nozzle (1300) into the circulation passage (820), and at the same time, the remaining water that is not discharged from the direct water nozzle (1300) to the circulation passage (820) is promoted for discharge by the steam of the steam supply unit (2000), so that the water remaining in the direct water nozzle (1300) can be minimized.

[0376] The above residual water discharge step (S30) may be terminated when the time set as the operating time has elapsed or when the water inside the direct water nozzle (1300) detected by the sensor of the direct water nozzle (1300) falls below a certain amount.

[0377] If the amount of water remaining inside the direct water nozzle (1300) does not reach a certain level even after the time set as the operating time of the residual water discharge step (S30) has elapsed, the residual water discharge step (S30) may be performed again.

[0378] When the above residual water discharge step (S30) is performed and the amount of water remaining inside the direct water nozzle (1300) is detected to be below a certain level and it is determined that the residual water removal of the direct water nozzle (1300) is complete, the residual water discharge step (S30) for removing residual water can be ended.

[0379] When the above residual water discharge step (S30) is terminated, the operation of the circulation fan (950) may be terminated to prevent power consumption, etc.

[0380] Figure 14 illustrates an embodiment in which the garment treatment device of the present invention further includes a circulation washing unit.
