[0001] The present invention relates to a garment processing device and a control method thereof. More specifically, it relates to a garment processing device and a control method thereof capable of performing refresh operations such as sterilization, wrinkle removal, deodorization, and drying of garments by supplying steam and hot air to the garments.

[0002] A garment processing device refers to a washing machine that washes items such as clothing through a washing process and a dryer that dries items through a drying process. Generally, while washing machines and dryers may be provided as separate devices, there are garment processing devices capable of performing washing and drying simultaneously to overcome space constraints and enhance user convenience.

[0003] For the execution of a laundry process, the garment processing device is equipped with a cabinet, a tub for storing water, a drum providing a space for accommodating a processing object, a driving unit fixed to the tub for rotating the drum, a support unit for supporting the tub, a water supply unit for supplying water to the tub, and a drainage unit for draining water from the tub.

[0004] Meanwhile, for the execution of the drying process, the garment processing device is equipped with a circulation duct that draws out air from inside the tub and recirculates it to the tub, and a heat exchanger that sequentially performs dehumidification and heating of the air.

[0005] That is, among conventional garment processing devices, there was one in which both a device for the washing process and a device for the drying process were installed inside the cabinet, allowing the washing and drying processes to be selectively executed according to the user's convenience.

[0072] FIG. 1 illustrates the clothing processing device of the present invention.

[0073] The clothing processing device of the present invention may include a cabinet (100) forming an exterior and a clothing receiving section (200) provided to store clothing inside the cabinet (100).

[0074] The clothing receiving section (200) may include a drum (220) for storing clothing inside the cabinet (100). The drum (220) may be provided to rotate the clothing inside the cabinet (100).

[0075] Alternatively, the clothing receiving section (200) may further include a tub (210) for storing water inside the cabinet (100), and the drum (220) may be rotatably provided inside the tub (210).

[0076] The cabinet (100) may include a front panel (110) having an opening (111) communicating with the interior of the drum (220), side panels (150) arranged on both sides of the front panel (110), and a back panel (160) connecting the back of the side panels (150).

[0077] The above front panel (110) may be provided in a plate shape, and a door (112) for opening and closing the opening may be rotatably coupled.

[0078] The above front panel (110) may be equipped with an interface (I) that receives user commands or displays the status of the clothing processing device above the opening (111). At least a portion of the interface (I) may be provided as a touch panel.

[0079] The cabinet (100) may further include an installation panel (120) that is positioned above the opening of the drum (220) and coupled to side panels (150) positioned on both sides.

[0080] The above installation panel (120) may be equipped with a control panel capable of receiving commands to control the clothing processing device or displaying the operating status of the clothing processing device to the outside.

[0081] The above installation panel (120) can be positioned at the rear of the above front panel (110) (110) and can be coupled to the upper part of the front of the above side panel (150).

[0082] The above-described installation panel (120) may have a panel installation part (121) formed therein for fixing the front of the circulation duct (800) described later. The panel installation part (121) may be provided in a groove shape for mounting the rear of the circulation duct (800), or in a hole shape through which a fastening member, which is fastened to the rear of the circulation duct (800), passes.

[0083] The tub (210) may be provided in a cylindrical shape and may be provided with a tub inlet (213) at the front for introducing clothing. The tub inlet (213) may be provided to communicate with the opening of the front panel (110) and may also be provided to communicate with the inside of the drum (220).

[0084] The drum (220) may be provided with a cylindrical metal material with an open front, and may have a through hole on its outer surface so that water and detergent stored in the tub (210) can be introduced or discharged.

[0085] The clothing processing device of the present invention may further include a water supply and drainage unit (400) for supplying or draining water to the tub (210).

[0086] The above water supply and drainage unit (400) may include a water supply unit (410) that supplies water to the tub (210) and a drainage unit (420) that drains the water contained in the tub (210) to the outside of the cabinet (100).

[0087] The above water supply unit (410) may include a water supply valve (411) that receives water from an external water source, a water supply pipe (413) that guides the water supplied from the water supply valve (411) toward the tub (210), and a detergent box (412) that stores detergent and receives water supplied from the water supply valve (411) to supply the detergent to the tub (210).

[0088] The above water supply valve (411) can be connected to the back panel (160) and, if necessary, may be provided in multiple numbers to selectively open and supply water. The above water supply pipe (413) may also be provided in multiple numbers to supply water to at least one of the detergent box (411), the tub (210), and the circulation duct (800) described later.

[0089] The above drainage section (420) may include a drain pipe (421) extending from the lower part of the tub (210) and a drain pump (422) that provides power to discharge water discharged from the drain pipe (421) to the outside of the cabinet (100).

[0090] Additionally, the above-mentioned water supply and drainage unit (400) may further include a circulation unit (430) that recirculates water drained from the drain pipe (421) back into the tub (210).

[0091] The above circulation unit (430) may include a circulation nozzle (431) coupled to the tub inlet (213) to discharge water into the tub (210), and at least one of a circulation hose and a circulation pump that supply water discharged from the drain pipe (421) to the circulation nozzle (431).

[0092] The present invention may further include a base (600) forming the bottom surface of the clothing processing device. The base (600) may be provided to support the cabinet (100) on which the cabinet (100) is seated. Additionally, the base (600) may support electrical components such as the drainage pump (421).

[0093] The clothing processing device of the present invention may further include a support member (500) that supports the tub (210) inside the cabinet (100). The support member (500) may be provided with a plurality of suspensions, one end of which is connected to the tub (210) and the other end of which is connected to the base (600).

[0094] The garment processing device of the present invention may further include a circulation duct (800) capable of circulating air inside the tub (210). The circulation duct (800) may form a flow path for circulating air inside the drum (220) outside the tub (210). Thus, the garment processing device of the present invention may be equipped as a washing machine with a drying function.

[0095] Since components such as a drainage section (420) and a support section (500) are arranged in the lower part of the tub (210), the circulation duct (800) can be placed above the tub (210).

[0096] The clothing processing device of the present invention may further include a heat exchanger (900) for heating air moving through the circulation duct (800). The heat exchanger (900) may include a heat exchanger disposed inside the circulation duct (800) and a compressor (940) disposed outside the circulation duct (800) for supplying high-temperature refrigerant to the heat exchanger.

[0097] The compressor (940) may be positioned below the tub (210). Therefore, a wider space may be secured between the upper part of the tub (210) and the side panel (150) for installing the circulation duct (800). Accordingly, in the clothing processing device of the present invention, the circulation duct (800) may be extended and arranged in the front-rear direction. As a result, the circulation duct (800) extends in the same direction as the extension of the tub (210) and the drum (220), thereby reducing flow resistance and allowing hot air to be supplied evenly inside the drum (220).

[0098] Additionally, by omitting the compressor (940) above the tub (210), the circulation duct (800) can be positioned offset toward either of the two side panels (150) from the top of the tub (210), thereby expanding the cross-sectional area of ​​the circulation duct (800). Accordingly, the clothing processing device of the present invention can circulate a larger flow rate of air to the outside of the tub (210) than when the compressor (940) is positioned above the tub (210).

[0099] The clothing processing device of the present invention may further include an air circulation unit (1000) mounted on a circulation duct (800) to circulate air in the tub (210). Since the compressor (940) is not positioned at the top of the tub (210), the air circulation unit (1000) may be positioned at the rear of the circulation duct (800) to suck in air from inside the tub (210) and supply it into the circulation duct (800).

[0100] Additionally, since the compressor (940) is positioned below the tub (210), the air circulation unit (1000) can utilize the entire space between the top of the tub (210) and the side panel (150). As a result, the air circulation unit (1000) can be positioned with a diameter in the width direction and arranged to rotate around a vertical axis of rotation, thereby enabling the circulation of a more abundant flow rate.

[0101] As a result, in the clothing processing device of the present invention, the compressor (940) is positioned lower than the tub (210), so that a larger flow rate per unit time can circulate through the circulation duct (800), thereby increasing the drying efficiency.

[0102] Figure 2 illustrates the arrangement of the circulation duct and the heat exchanger.

[0103] The tub (210) is provided in a cylindrical shape extending in the front-rear direction, and the cabinet (100) is provided in an internal rectangular shape. Accordingly, in the upper region of the tub (210), more space is secured to the left and right of the center (O) in the width direction of the cabinet (100).

[0104] The above circulation duct (800) may be positioned offset from the center (O) in either the left or right direction. That is, the width-direction center of the above circulation duct (800) may also be positioned offset from the width-direction center (O) of the cabinet in either the left or right direction.

[0105] At this time, a portion of the circulation duct (800) may be arranged to overlap the width-direction center (O) and the height-direction of the cabinet. Additionally, a portion of the circulation duct (800) may be arranged spaced apart from the width-direction center (O) of the cabinet in either the left or right direction. As a result, the cross-sectional area of ​​the circulation duct (800) may be expanded.

[0106] Meanwhile, the compressor (940) may be positioned so as to be offset from the left or right side of the width direction center (O) of the cabinet (100) in the direction in which the circulation duct (800) is offset.

[0107] For example, the compressor (940) may be placed at the bottom of the circulation duct (800), and the circulation duct (800) and the compressor (940) may be placed so that at least a portion overlaps in the height direction.

[0108] As a result, the vertical distance between the circulation duct (800) and the compressor (940) can be reduced, and the length of the refrigerant pipe (950) connecting the compressor (940) and the heat exchanger placed inside the circulation duct (800) can be reduced. Accordingly, the refrigerant pipe (950) can be arranged in a straight line in the maximum height direction, thereby reducing the flow resistance of the refrigerant and minimizing heat loss occurring in the refrigerant pipe (950).

[0109] Meanwhile, the heat exchanger (900) of the present invention may further include a fixing plate (960) for fixing the refrigerant pipe (950) to the back panel (160) of the cabinet (100). The fixing plate (960) may be provided in the shape of a bracket in which at least one of the back and both sides of the refrigerant pipe (950) is mounted and the height is longer than the width. Thus, the refrigerant pipe (950) can be spaced apart from the tub (210) and supported by the fixing plate (850) and the cabinet (100), and vibrations generated in the tub (210) are prevented from being directly transmitted to the refrigerant pipe (950), thereby enhancing durability.

[0110] Consequently, the compressor (940), the circulation duct (800), the refrigerant pipe (950), and the fixing plate (960) can all be positioned on the left side of the tub (210) or on the right side of the tub (210). Thus, the compressor (940), the circulation duct (800), the refrigerant pipe (950), and the fixing plate (960) can all be easily installed, repaired, and replaced when a single side panel (150) is removed.

[0111] The above circulation duct (800) may include a duct body (810) on which the heat exchanger is seated, and a duct cover (820) coupled to the duct body (810) to shield the duct body (810).

[0112] The above duct body (810) may be provided in a case shape or duct shape with an open top, and the above duct cover (820) may be provided in a plate shape or case shape corresponding to the shape of the duct body (810).

[0113] The above duct body (810) may include a rear connecting part (850) connected to the rear of the tub (210) and communicating with the tub (210), and a front connecting part (840) connected to the front of the tub (210) and communicating with the tub (210).

[0114] The rear connecting part (850) and the front connecting part (840) may be provided in the shape of a duct or pipe through which air can move. The rear connecting part (850) and the front connecting part (840) may be provided with an elastic material. Thus, even if the tub (210) vibrates, the vibration of the tub (210) can be prevented from being transmitted to the duct body (810).

[0115] The above circulation duct (800) may be connected to the tub (210) only at the front connection part (840) and the rear connection part (850), and the duct body (810) may be spaced apart from the tub (210). It may further include a bracket (830) that fixes the position of the rear connection part (850) by fixing the rear connection part (850) to the tub (210).

[0116] The bracket (830) can be positioned at the bottom of the duct body (810) and seated on the tub (210). Thus, even if the duct body (810) is positioned to block the air inlet / outlet of the tub (210), the position of the rear connecting part (850) is fixed through the bracket (830), allowing the air inlet / outlet of the tub (210) and the duct body (810) to be easily connected via the rear connecting part (850).

[0117] FIG. 3 illustrates the structure of the base and the back panel.

[0118] The above base (600) may include a base body (610) that supports the load of the clothing processing device and an installation groove (620) that is recessed in at least one of the left and right sides of the base body (610).

[0119] The above installation groove (620) may be positioned offset to one side of the base body (610) and may be positioned at the rear of the base body (610). The above installation groove (620) may form a space on which the compressor (940) is seated.

[0120] The clothing processing device of the present invention may further include a control unit or a control panel (2000) capable of controlling electrical components placed in the clothing processing device. A circulation duct (800) may be installed on one side of the upper part of the tub (210), and a detergent box or a water storage tank, etc., may be installed on the other side. Accordingly, the control panel (2000) may be installed on the base body (610) and positioned below the tub (210).

[0121] The control panel (2000) may be positioned on the base body (610) spaced apart from the installation groove (620). For example, the control panel (2000) may be positioned offset to the other side of the base body (610). As a result, the control panel (2000) may be prevented from being exposed to heat generated by the compressor (940). Additionally, by positioning the control panel (2000) and the compressor (940) on both lower sides of the tub (210), interference between the control panel (2000) and the compressor (940) and the tub (210) may be prevented.

[0122] The control panel (2000) may include an HP case (2100) that controls the heat exchanger (900) and a main PCB (2200) coupled to the HP case (2100) to control electrical components other than the heat exchanger (900). Since the HP case (2100) has a larger volume and generates more heat than the main PCB (2200), the control panel (2000) may include a panel fan (2300) coupled to one side of the HP case (2100) to cool the HP case (2100). Additionally, the control panel (2000) may further include a noise filter (2300) capable of removing noise from current supplied from various sensors of the clothing processing device or external power, or from electrical signals generated from the HP case (2100) and the main PCB (2200). The noise filter (2300) may be mounted on the upper part of the main PCB (2200) to receive current or transmit a current signal.

[0123] The above rear panel (160) may be provided with a panel fixing part (161) on the upper part for fixing the rear of the circulation duct (800). The panel fixing part (161) may be provided in a groove shape for mounting the rear of the circulation duct (800), or in a hole shape through which a fastening member that is fastened to the rear of the circulation duct (800) passes.

[0124] Figure 4 illustrates the structure of the above tub.

[0125] The above tub (210) may include a cylindrical tub body and a tub inlet (213) provided at the front of the tub body through which clothing can be inserted.

[0126] The diameter of the tub inlet (213) may be smaller than the diameter of the tub body. The circulation part (430) may be coupled and fixed to the outer surface of the tub inlet (213).

[0127] The above tub body may be formed by dividing it into a front body and a rear body and joining them together, or it may be molded as a single unit.

[0128] The above tub (210) may further include an air outlet (211) provided at the upper rear of the tub body for discharging air inside the tub (210), and an air inlet (212) provided at the upper part of the tub inlet (213) for receiving air discharged from the circulation duct (800).

[0129] The air outlet (211) may be formed offset to one side from the top of the tub body. By doing so, the air outlet (211) can be extended at a position lower than the top of the tub body, thereby ensuring sufficient space for the air circulation unit (1000) to be installed.

[0130] The air inlet (212) may be formed at the top of the tub inlet (213).

[0131] The above tub (210) may further include a vent hole (215) that is offset to the other side from the top of the tub body and communicates with the outside, and a connecting pipe (216) that communicates the vent hole (215) with the outside of the cabinet (100).

[0132] FIG. 5 illustrates the state in which a circulation duct is installed in the above tub.

[0133] FIG. 5(a) illustrates the tub viewed from the front, and FIG. 5(b) illustrates the tub viewed from the rear.

[0134] The above circulation duct (800) may include a duct body (810) that receives air from an air outlet (211) formed at the upper rear of the tub (210) and discharges air to an air inlet (212) formed at the upper front of the tub (210), and a duct cover (820) that is coupled to the upper part of the duct body (810) and shields the inside of the duct body (810).

[0135] The above duct body (810) can be extended from the rear to the front and can be arranged in a direction corresponding to the front-rear direction of the tub (210) and the drum (220). By doing so, the air resistance flowing through the clothing receiving section (200) and the circulation duct (800) can be reduced.

[0136] The rear connecting part (850) may be provided to connect the rear of the duct body (810) and the air outlet (211), and the front connecting part (840) may be provided to connect the front of the duct body (810) and the air inlet (212).

[0137] The front connecting part (840) may be provided in a square duct shape or in a bellows type. One end or the upper end of the front connecting part (840) may be connected to the duct body (810), and the other end or the lower end may be connected to the air inlet (212).

[0138] The above rear connecting part (850) may be provided in a pipe shape or in a zarab type.

[0139] However, the rear connecting part (850) may be positioned between the duct body (810) and the tub body. Accordingly, the duct body (810) may pressurize the rear connecting part (850) toward the air inlet (212) due to the load. Accordingly, the rear connecting part (850) may be provided such that one end or the upper end is connected to or in close contact with the duct body (810), and the end or lower end is connected to or in close contact with the air inlet (212).

[0140] The above air circulation unit (1000) may be positioned at least partially between the duct body (810) and the duct cover (820), and may be positioned closer to the rear than to the front of the duct body (810).

[0141] The air circulation unit (1000) may be configured to suck in air from the air outlet (211) and supply it into the duct body (810). That is, the air circulation unit (1000) may supply air from inside the tub (210) into the circulation duct (800) at positive pressure.

[0142] A drive unit (300) for rotating the drum (220) may be coupled to the rear of the tub (210). The drive unit (300) may be provided as an outer rotor type.

[0143] FIG. 6 illustrates the positional relationship between the circulation duct of the present invention and the tub.

[0144] The above circulation duct (800) is provided with a resin-based material, and the heat exchanger housed inside may be provided with a metal material. Therefore, the above circulation duct (800) may be susceptible to vibration. In addition, since the above circulation duct (800) has a large self-weight due to the heat exchanger and the air circulation unit (1000), it may vibrate with a frequency and amplitude separate from the vibration of the tub (210). As a result, if the above circulation duct (800) is directly seated on the tub (210), a problem may occur in which the above circulation duct (800) and the above tub (210) collide with each other or, in severe cases, are damaged. Therefore, the above circulation duct (800) may be installed inside the cabinet (100) while maintaining a certain distance from the above tub (210).

[0145] The front connecting part (840) and the rear connecting part (850) are coupled to the tub (210), and the duct body (810) may be positioned such that its lower surface is spaced apart from the tub (210) by a specific distance (h). The front connecting part (840) and the rear connecting part (850) are provided with an elastic material to block vibrations and noise from the tub (210) from being transmitted to the duct body (810).

[0146] FIG. 7 illustrates a specific structural embodiment of the above-mentioned duct body.

[0147] The above duct body (810) may include an inlet duct (811) that receives air from the air outlet (211), a fan housing (812) that extends from the inlet duct (811) and accommodates the air circulation unit (1000), a connecting duct (813) that extends forward from the fan housing (812), an installation duct (814) that extends forward from the connecting duct (813) and installs a heat exchanger, and an exhaust duct (815) that extends forward or downward from the installation duct (814) and discharges air to the air inlet (212). The connecting duct and the installation duct together may be referred to as a moving duct that forms the air flow path of the air passing through the inlet duct.

[0148] The above inlet duct (811) may be positioned above the air outlet (211) and may be positioned overlapping the air outlet (211) in the height direction.

[0149] The above inlet duct (811) may be provided in the shape of a pipe or in the shape of a through hole so that the above rear connecting part (850) can be connected.

[0150] The rear connecting part (850) may have one end or lower end connected to or in contact with the air inlet (212), and the other end or upper end connected to or in contact with the inlet duct (811).

[0151] The above-mentioned fan housing (812) may be provided in a circular or spiral shape.

[0152] The above fan housing (812) is provided to be larger than the diameter or area of ​​the above inlet duct (811) so as to secure a space for the air circulation unit (1000) to be installed.

[0153] The above air circulation unit (1000) may be installed in the fan housing (812) to suck in air from the tub (210) and supply it to the heat exchanger.

[0154] The above connecting duct (813) may extend forward from one side of the fan housing (812). The above connecting duct (813) may guide the radial air flow formed by the air circulation unit (1000) forward.

[0155] The above connecting duct (813) may be configured so that its cross-sectional area gradually widens from the rear toward the front. As a result, the air supplied by the air circulation unit (1000) can be evenly distributed while slowing down the flow velocity.

[0156] The above installation duct (814) is provided with a width greater than that of the connecting duct (813) so that the heat exchanger can be seated thereon.

[0157] The above installation duct (814) can form a space in which the evaporator and condenser described later are seated.

[0158] The exhaust duct (815) may be formed with a smaller diameter than the installation duct (814). The exhaust duct (815) may be formed so that its width decreases as it extends forward from the installation duct (814). The end of the exhaust duct (815) may be provided with an area and shape corresponding to the air inlet (212).

[0159] The above exhaust duct (815) is extended forward from the above installation duct (814) with a reduced width and can form an opening at the lower front.

[0160] The above duct body (810) may further include a receiving rib (816) that partitions the fan housing (812) and the connecting duct (813) and accommodates the air circulation section (1000).

[0161] The receiving rib (816) may be provided to discharge air circulating around the inner surface of the fan housing (812) forward. That is, the receiving rib (816) can perform the function of an outlet of the fan housing (812) together with one side of the installation duct (813).

[0162] The clothing processing device of the present invention may further include a fixing part (860) that fixes the front and rear of the circulation duct (800) to the cabinet (100) to separate the circulation duct (800) from the tub (210).

[0163] The above fixing part (860) may include a front fixing part (861) provided at the front of the duct body (810) and fixed to the installation panel (120), and a rear fixing part (862) provided at the rear of the duct body (810) and fixed to the rear panel (160).

[0164] For example, the front fixing part (861) may be provided so that a fastening member, etc., can be attached to the front of the exhaust duct (815).

[0165] Additionally, the front fixing part (861) may be provided in the shape of a protruding projection that protrudes from the front of the exhaust duct (815). The front fixing part (861) may be provided in multiple numbers and arranged spaced apart in the width direction in front of the exhaust duct (815). The front fixing part (861) may be inserted into and seated in the panel installation part (121).

[0166] For example, the rear fixing part (862) may be provided so that a fastening member, etc., can be attached to the rear of the fan housing (812).

[0167] Additionally, the rear fixing part (862) may be provided in the shape of a protruding projection that protrudes from the rear of the fan housing (812). The rear fixing part (862) may be provided in multiple numbers and arranged spaced apart in the width direction at the rear of the fan housing (812). The rear fixing part (862) may be inserted into and seated in the panel fixing part (161).

[0168] FIG. 8 illustrates an example of a structure in which a duct body communicates with a tub.

[0169] The above duct body (810) can be extended from the rear to the front of the tub.

[0170] Additionally, the duct body (810) may be provided with a wide width to accommodate the diameter of the air circulation section (1000) in the width direction and to further expand the cross-sectional area. As a result, the duct body (810) may be arranged to completely overlap in the height direction from the upper part of the air outlet (211) to the upper part of the air inlet (212).

[0171] Since the air inlet (212) is provided in the tub inlet (213), a space can be formed in which the front connecting part (840) is installed in front of the tub (210).

[0172] However, since the air outlet (211) extends upward from the tub body, if the inlet duct (811) is positioned above the air outlet (211), there may be insufficient space for the rear connecting part (850) to be installed or assembled between the air outlet (211) and the inlet duct (811).

[0173] Accordingly, the bracket (830) may be provided to be seated on the upper part of the tub body to connect the rear connecting part (850) to the air outlet (211). The bracket (830) may be coupled to the upper part of the tub body and bring the lower end of the rear connecting part (850) into close contact with the air outlet (211).

[0174] The rear connecting part (850) can be connected to the inlet duct (811) at its upper end while fixed to the bracket (830). The duct body (810) can fix the position of the rear connecting part (850) by pressing the rear connecting part (850) toward the bracket (830).

[0175] The above bracket (830) may include a bracket body (831) that is seated on the tub body and provided in a plate shape, and a coupling hole (832) provided to penetrate the bracket body. The air outlet (211) may be provided protruding upward from one side of the tub body, and the coupling hole may be positioned spaced above the air outlet, and the bracket body may be provided in a plate shape extending in the width direction so as to be seated on the upper surface of the tub body.

[0176] Figure 9 illustrates the internal configuration of a circulation duct.

[0177] The above air circulation unit (1000) can be positioned above the inlet duct (811).

[0178] The above air circulation unit (1000) may include an impeller (1100) that is housed in the fan housing (812) and introduces air inside the tub body, a fan motor (1200) that is mounted on the outside of the duct cover (820) and provides power to rotate the impeller (1100), and a rotating shaft (1300) that passes through the duct cover (820) and connects the fan motor (1200) and the impeller (1100).

[0179] The heat exchanger (900) may include an evaporator (910) seated in the installation duct (814) and a condenser (920) spaced apart from the evaporator (910) toward the exhaust duct (815).

[0180] The above evaporator (910) may be positioned behind the above condenser (920) and close to the air circulation unit (1000), and the above condenser (920) may be connected to the compressor (940) and the refrigerant pipe (950) to receive high-temperature refrigerant.

[0181] When the fan motor (1200) rotates the impeller (1100), the air inside the tub (210) can be introduced into the inlet duct (811) (1). The air introduced into the inlet duct (811) can be introduced into the installation duct (814) along the connecting duct (813) while rotating radially by the impeller (1100). The air introduced into the installation duct (814) can be cooled as it passes through the evaporator (910) to condense moisture, and can be heated as it passes through the condenser (920) (2).

[0182] The air that has passed through the condenser (920) can be discharged through the exhaust duct (815) and then discharged through the air inlet (212) (3 times).

[0183] This process is performed continuously so that the clothing contained in the drum (220) can be dried.

[0184] Figure 10 illustrates the internal structure of a circulation duct.

[0185] Referring to FIG. 10(a), the diameter (w2) of the fan housing (812) may be larger than half the width (w1) of the installation duct. Thus, as shown in FIG. 10(b), the impeller (1100) may be positioned to rotate around a vertical axis of rotation (1300). As a result, more air inside the tub (210) can be drawn into the duct body (810) with greater force and without loss.

[0186] That is, the diameter (R) of the impeller (1100) is provided to be longer than the thickness (H), and the impeller (1100) can be accommodated inside the fan housing (812) such that the diameter (R) is arranged in the width direction and the thickness (H) is arranged in the up-down direction.

[0187] Referring to FIG. 10(a), due to the receiving rib (816), the rear or inlet width (W3) of the connecting duct (813) can be formed to be smaller than the width of the installation duct (W1) and smaller than the diameter (W2) of the fan housing (812). Additionally, the connecting duct (813) can be configured so that its width gradually increases as it faces the evaporator (810).

[0188] Thus, the connecting duct (813) can function as a diffuser that evenly disperses the air supplied from the fan housing (812) in the width direction toward the front.

[0189] The clothing treatment device of the present invention may further include a nozzle part (3000) capable of cleaning the evaporator (910) by spraying water onto the evaporator (910).

[0190] The nozzle section (3000) may be configured to receive water from the water supply section (410) and spray it onto the evaporator (910). The nozzle section (3000) may be arranged to extend in the width direction of the evaporator (910) so as to supply water to the entire rear surface of the evaporator (910).

[0191] The above circulation duct (800) may be provided to discharge water condensed in the evaporator (910) and water sprayed into the evaporator (910) back to the drain (420) or the tub (210).

[0192] The rear surface of the evaporator (910) corresponds to the area where it is first exposed to the air introduced from the tub (210). Accordingly, the nozzle part (3000) can spray water onto the rear of the evaporator (910) to remove foreign matter adhering to the rear surface of the evaporator (910).

[0193] FIG. 11 illustrates a structure for supplying water to the above-mentioned circulation duct.

[0194] The nozzle part (3000) can be positioned between the lower part of the duct cover (820) and the evaporator (910).

[0195] The above water supply unit (410) may include a water supply pipe (413) connected to the above water supply valve (411) to supply water to the above nozzle unit (3000).

[0196] The above water supply pipe (413) is provided in multiple numbers and can extend from the water supply valve (411) toward both ends of the nozzle section (3000). As a result, water can be evenly supplied to the entire width of the nozzle section (3000).

[0197] FIG. 12 illustrates the connection between the circulation duct and the air inlet.

[0198] Referring to FIG. 12, FIG. 12 illustrates the connection between the circulation duct and the air inlet.

[0199] The connection portion configured to communicate between the tub (210) and the circulation duct (800) may include a front connection portion (840) configured to connect the air inlet (212) and the exhaust duct (815), and a rear connection portion (850) configured to connect the air outlet (211) and the inlet duct (811).

[0200] Referring to FIG. 12, the exhaust duct (815) may protrude forward of the air inlet (212) such that at least a portion of the air inlet overlaps in the vertical direction. This ensures a gap between the exhaust duct and the tub (210), thereby preventing damage to the exhaust duct caused by vibration of the tub.

[0201] Since the exhaust duct (815) protrudes forward from the air inlet (212), the front connecting part (840) may be provided at an angle so as to gradually move forward from the front of the tub (210) as it gets closer to the exhaust duct from the air inlet.

[0202] The above-mentioned front connecting part (840) may be configured to connect the exhaust duct (815) and the air inlet (212) at an angle such that the upper part is positioned further forward than the lower part. This allows the gap with the tub (210) to widen as it goes toward the top, and reduces the frequency of contact with the front connecting part caused by vibrations occurring in the tub, thereby preventing damage to the front connecting part.

[0203] Meanwhile, the front connecting part (840) may be provided to include an upper connecting part (841) coupled to the exhaust duct (815), a lower connecting part (843) coupled to the air inlet (212), and a front connecting pipe (8421) configured to connect the upper connecting part and the lower connecting part.

[0204] The upper coupling portion (841) is provided to surround the outer surface of the exhaust duct (815) and can be press-fitted. For example, the exhaust duct may be provided with a rib protruding outward, and the upper coupling portion may be provided with a groove of a size corresponding to a position corresponding to the rib. In addition, a fastening portion (870) surrounding the outer surface of the upper coupling portion may be provided to improve the coupling force. The fastening portion will be described below.

[0205] The lower coupling portion (843) is provided to surround the outer surface of the air inlet (212) so as to be press-fitted. For example, the air inlet may be provided with a rib protruding outward, and the lower coupling portion may be provided with a groove of a size corresponding to a position corresponding to the rib. In addition, a fastening portion (870) surrounding the outer surface of the lower coupling portion may be provided to improve the coupling force. The fastening portion will be described below.

[0206] The above-mentioned front connecting tube (842) may be provided in the form of a corrugated tube (8421) with a variable length. For example, it may be provided as a bellows tube. The corrugated tube may be provided to include an extension tube (84211) that does not contract in the vertical direction and a contraction tube (84212) that protrudes outward from the extension tube and is provided to be contractible in the vertical direction.

[0207] The corrugated tube (8421) may be provided at an angle such that as it approaches the upper coupling part (841) from the lower coupling part (843), it moves further away from the tub (210). By doing so, a space between the tub and the corrugated tube is secured, thereby preventing damage to the front connecting part (840) caused by vibration of the tub.

[0208] Additionally, the upper coupling part (841) may be coupled to the discharge duct (815) so as to be parallel to the ground, and the lower coupling part (843) may be coupled to the air inlet (212) so as to be parallel to the ground. In this case, the corrugated pipe (8421) may be provided to be inclined to the ground by varying the length of the contraction pipe (84212).

[0209] Meanwhile, by varying the length of the above-mentioned shrink pipe (84212), the exhaust duct (815) provided in the circulation duct (800) fixed to the cabinet (100) and the air inlet (212) provided in the tub (210) can remain connected even if their relative positions change.

[0210] Additionally, the corrugated tube (8421) can be formed into a curve by cutting the surface adjacent to the tub (210). This minimizes contact with the tub, and even if contact occurs, the curved shape increases the contact area, thereby reducing stress and preventing breakage.

[0211] FIG. 13 illustrates the connection relationship of the rear connecting pipe connecting the air outlet and the inlet duct.

[0212] The rear connecting portion (850) may include a first connecting portion (851) that is coupled to the air outlet (211). The first connecting portion may be seated on the top of the air outlet and extend inwardly downward to be received by the air outlet, and then extend upward. That is, the first connecting portion may be extended so as to be convex downward.

[0213] Additionally, the rear connecting portion (850) may include a connecting pipe (853) that extends upward from the first connecting portion (851) and forms a passage for air discharged from the air outlet.

[0214] The connecting pipe (853) extends from the first coupling part (851), and since the first coupling part extends from the inner circumference of the air outlet, the diameter of the connecting pipe can be smaller than the diameter of the air outlet (211). As a result, the air flow path can be formed to be close to a straight line, thereby reducing flow resistance.

[0215] Additionally, the rear connecting portion (850) may include a second connecting portion (852) that extends convexly upward from the connecting pipe (853) and extends radially outward from the discharge duct (811) to surround the outer surface of the discharge duct.

[0216] The above exhaust duct (811) may be provided with a diameter larger than that of the air outlet (211), and the second coupling part (852) may be provided so that at least a portion is received in the exhaust duct.

[0217] Meanwhile, the bracket (830) may be provided to be seated on the upper surface of the first coupling part (851) seated on the upper end of the air outlet (211) to press the first coupling part.

[0218] FIG. 14 illustrates a cross-section of the joint structure of the rear connecting pipe connecting the air outlet and the inlet duct.

[0219] The air outlet (211), the rear connecting part (850), and the coupling hole (832) may be provided such that at least a portion overlaps in the height direction. By doing so, the distance between the air outlet and the coupling hole can be shortened, and the length of the rear connecting part can be minimized.

[0220] Meanwhile, the rear connecting part (850) includes a first connecting part (851) coupled to the air outlet (211), a second connecting part (852) located above the first connecting part and coupled to the inlet duct (811), and a connecting pipe (853) connecting the second connecting part, wherein the diameter of the connecting pipe may be smaller than the diameter of the air outlet. That is, the connecting pipe (853) may be positioned to the inner side of the inner surface of the air outlet. Compared to the case where the connecting pipe is positioned to the outer side of the outer surface of the air outlet, collision with the tub (210) can be minimized, thereby preventing damage.

[0221] Likewise, the diameter of the connecting pipe (853) may be smaller than the diameter of the inlet duct (811). That is, the connecting pipe (853) may be positioned on the inner side of the inner surface of the inlet duct. Compared to the case where the connecting pipe is positioned on the outer side of the outer surface of the inlet duct, collision with the tub (210) can be minimized, thereby preventing damage.

[0222] Additionally, the diameter of the connecting pipe (853) may be smaller than the diameter of the first connecting part (851). That is, the first connecting part may be provided to extend outward from the connecting pipe and be connected to the air outlet (211).

[0223] Likewise, the diameter of the connecting pipe (853) may be smaller than the diameter of the second connecting part (852). That is, the second connecting part may be provided to extend outward from the connecting pipe and be connected to the inlet duct (811).

[0224] Meanwhile, the diameter of the second coupling part (852) may be larger than the diameter of the first coupling part (851). This is because the diameter of the inlet duct (811) may be larger than the diameter of the air outlet (211).

[0225] Additionally, the diameter of the connecting pipe (853) may be smaller than the diameter of the coupling hole (832). Accordingly, the connecting pipe is press-fitted by contacting the inner surface of the coupling hole and supported by the bracket (830), so that its position may not change significantly. Thus, even if the tub (210) vibrates, the connection between the connecting pipe, the inlet duct (811), and the air outlet (211) can be maintained.

[0226] Meanwhile, referring to FIG. 14, the second coupling part (852) includes a second protruding curved surface (8522) that protrudes convexly upward from the upper end of the connecting pipe (853) and extends radially outward from the connecting pipe, and the second coupling part can be coupled to the inlet duct such that the second protruding curved surface is located inside the inlet duct (811). By doing so, the area protruding outward from the inlet duct can be reduced, thereby preventing damage caused by contact due to vibration of the tub (210).

[0227] Additionally, the second coupling portion (852) may include a second coupling surface (8523) that is provided to be coupled with the inlet duct by extending outwardly from the second protruding curved surface (8522) to surround the outer surface of the inlet duct (811). The outer surface of the inlet duct may be provided with a groove cut inward, and the second coupling surface may be provided with a rib protruding from its inner surface to be coupled to the groove.

[0228] Additionally, a rib protruding outward from the outer surface of the second coupling surface (8523) may be provided, and a clamp provided to be seated on the rib and surround the outer surface of the second coupling surface may be provided to fix the second coupling surface and the inlet duct (811).

[0229] The second coupling surface (8523) may be provided spaced outward in the radial direction of the connecting tube (853).

[0230] FIG. 15 illustrates the connection structure of the first joint, the bracket, and the air outlet.

[0231] Referring to FIG. 15, the first coupling part (851) may include a first protruding curved surface (8512) that protrudes convexly downward from the bottom of the connecting pipe (853) and extends radially outward from the connecting pipe, and the first protruding curved surface may be positioned inside the air outlet (211). By positioning the first protruding curved surface inside the air outlet, the collision between the tub (210) and the first coupling part can be minimized, thereby preventing damage.

[0232] That is, the first protruding curved surface (8521) may be provided to be in contact with the inner circumferential surface of the air outlet (211), the upper end of the first protruding curved surface may be provided at a position corresponding to the upper end of the air outlet, and the first coupling surface (8513) may be extended outward from the upper end of the first protruding curved surface toward the upper end of the air outlet and may be seated on the upper end of the air outlet.

[0233] Additionally, the first coupling portion (851) may include a first coupling surface (8513) that extends outward from the first protruding curved surface (8512) and is seated on the top of the air outlet (211). The first coupling surface is located between the top of the air outlet and the bracket (830), is fixed by being pressurized by the top of the air outlet and the bracket, and can seal the air flowing from the air outlet toward the inlet duct (811).

[0234] That is, the outer surface of the coupling hole (832) is bent downward from the bracket body (831) and the bent portion is surrounded by the upper surface of the first protruding curved surface (8512), so that the coupling hole can be supported by the first protruding curved surface. By doing so, the coupling force between the bracket (830) and the rear connecting portion (850) can be improved.

[0235] Additionally, the first coupling surface (8513) may include a buffer groove (85131) provided such that the lower surface is recessed to accommodate the upper end of the air outlet. By doing so, the coupling force between the first coupling surface (8513) and the upper end of the air outlet (211) can be increased.

[0236] Meanwhile, the connecting tube (853) may include a support projection (8532) that protrudes outward from the outer surface and is provided to be seated on the upper surface of the bracket body (831). By doing so, the bracket body is positioned and supported between the support projection and the first coupling surface (8513), thereby improving the coupling force between the bracket (830) and the rear connecting part (850).

[0237] FIG. 16 illustrates an upward view of the rear connecting part penetrating the coupling hole.

[0238] The above-mentioned connecting tube (853) includes a ring-shaped connecting ring (8533) that extends outward from the outer surface and protrudes outside the connecting hole, and the above-mentioned bracket body (831) includes a projection-shaped protruding rib (8314) that is provided at a position corresponding to the connecting ring and extends outward from the outer surface, and the connecting ring can be connected to the protruding rib. The connecting ring is located above the bracket body, and since the connecting ring is provided with an elastic material and can extend outward in the radial direction of the connecting tube, it can be caught on the protruding rib, and the connecting ring and the protruding rib can be connected by the restoring force of the connecting ring. That is, the connecting ring and the protruding rib can be connected by an interference fit.

[0239] The bracket (830) and the rear connecting part (850) can be connected to the air outlet (211) while connected to each other. When the bracket and the rear connecting pipe are moved to be connected to the air outlet, the connecting ring (8533) and the protruding rib (85314) can be connected, and the connecting ring and the protruding rib can be prevented from being separated by an external force applied while moving.

[0240] Meanwhile, when the bracket is seated on the tub (210) and the rear connecting part is coupled to the tub outlet (211), there is no risk of the bracket and the rear connecting part being separated, so the coupling ring and the protruding rib can be released from the connection. This prevents the connecting tube (853) from being deformed by the tensile force applied to the coupling ring.

[0241] Meanwhile, the bracket body (831) may include rib grooves (8315) that are recessed on both sides of the protruding rib and into which the coupling ring is seated. The rib grooves provide a space for the coupling ring to be seated, thereby preventing the protruding rib (8314) from coming off.

[0242] Additionally, the protruding rib (8314) may be provided in multiple numbers and may include a first protruding rib (83141) provided in front of the coupling hole and a second protruding rib (83142) positioned behind the coupling hole and facing the first protruding rib. The coupling ring (8533) may include a first coupling ring (85331) coupled to the first protruding rib and a second coupling ring (85332) coupled to the second protruding rib. The first coupling ring may include a lower indicator (85331a) protruding into the ring, and the first protruding rib may be provided with a lower confirmation part (83141a) at a position corresponding to the lower indicator. By doing so, coupling can be induced so that the direction of the rear connecting part (850) is correctly positioned.

[0243] Additionally, the connecting pipe (853) may be coupled to pass through the coupling hole (832) so as to protrude further upward than downward from the bracket body (831). This is because the distance between the bracket body and the inlet duct (811) is longer than the distance between the bracket body and the air outlet (211).

[0244] Since the lower confirmation part (83141) is provided on the upper surface of the bracket body (831), the rear connecting part (850) and the bracket (830) are connected so that the lower indicator part (85331a) and the lower confirmation part face each other, thereby allowing the connection to be induced so that the connecting pipe (853) is provided longer upward than downward from the bracket body (831).

[0245] FIG. 17 illustrates the state in which the rear connection part and the inlet duct are combined.

[0246] The second coupling part (852) includes an upper indicator part (8521) that is recessed inward from the outer surface, and the inflow duct (811) may be provided at a position corresponding to the upper indicator part and may have an upper verification part (8111) that protrudes outward from the outer surface of the inflow duct. By doing so, the second coupling part and the inflow duct (811) can be induced to be coupled so that the upper indicator part and the upper verification part are at corresponding positions.

[0247] When the upper confirmation part (8111) and the upper display part (8521) are combined so as to face each other, the rear connection part (850) and the inflow duct (811) can be combined in the correct direction.

[0248] FIG. 18 illustrates the state in which the connecting ring is connected to the protruding rib.

[0249] The above connecting ring (8533) may be provided with an elastic material. Thus, it may be provided to extend radially outward from the rear connecting part (850) and engage with the protruding rib (8314).

[0250] By providing the above connecting ring (8533) to be caught on the above protruding rib (8314), the rear connecting part (850) can be fixed to the bracket (830) and transported, thereby allowing the rear connecting part to connect the air outlet (211) and the exhaust duct (811) in the correct position.

[0251] In addition, since the rib grooves (8315) are provided on both sides of the protruding rib (8314), the coupling ring (8533) can be prevented from detaching from the protruding rib (8314) during transport.

[0252] Figure 19 shows the upper surface of the bracket.

[0253] Referring to FIG. 19, the bracket body (831) may be provided in a plate shape that is longer than the width of at least a portion of the circulation duct (800). Referring to FIG. 8, it may be provided to protrude outward from the lower part of the fan housing (812) to the outside of the fan housing. That is, the bracket body (831) may be provided in a plate shape that is longer than the width of the fan housing. Thus, the bracket body may be provided with a portion that is provided below the circulation duct but does not overlap with the circulation duct, and may be coupled with the tub (210) at a position that does not overlap with the circulation duct.

[0254] Additionally, the bracket body (831) may be designed to avoid parts placed on the upper surface of the tub. For example, a portion may be cut or bent, and may be penetrated as needed.

[0255] Meanwhile, the bracket body (831) may be provided in a plate shape corresponding to the upper surface of the tub (210). For example, the bracket body may be a plate provided to have a circular shape identical to the upper surface of the tub, but it may be provided to correspond to the curvature of the tub so as to be in contact with a part of the upper surface curve and spaced apart from a part thereof.

[0256] Fig. 20 shows the side view of the bracket.

[0257] Specifically, referring to FIG. 20, the bracket body (831) includes a coupling body (8311) comprising the coupling hole (832), and a stepped body (8312) that extends from the coupling body to the other side and is provided with a height that increases as it approaches the other side, and the stepped body may be provided such that at least a portion is spaced apart from the upper surface of the tub.

[0258] Thus, the bracket body (831) is provided to correspond to the curvature so that it can be stably seated on the tub (210), and is provided to be spaced apart from a part of the tub so that friction caused by vibration of the tub can be partially avoided, thereby preventing damage.

[0259] Additionally, the bracket body (831) may include a vibration hole (8313) provided to penetrate the stepped body (8312). The vibration hole is located at a portion separated from the stepped body and the tub, thereby reducing to a certain extent the impact of the tub on the bracket body caused by the vibration of the tub.

[0260] The present invention may be modified and implemented in various forms, and its scope of rights is not limited to the embodiments described above. Therefore, if a modified embodiment includes the components of the claims of the present invention, it should be considered to fall within the scope of rights of the present invention.
