Description

Clothing processing device

[0001] The present invention relates to a garment processing device. More specifically, it relates to a garment processing device 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 laundry administration, the garment processing device is equipped with a cabinet, a tub for storing water, a drum providing a space for accommodating the object to be processed, 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 provided in the circulation duct that sequentially performs dehumidification and heating of the air.

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

[0006] In addition, there was a conventional garment processing device equipped with both washing and drying processes in which a heat exchanger was provided above the tub, and the inlet and outlet of the circulation duct equipped with the heat exchanger were arranged on one side.

[0007] Meanwhile, in the case of the prior art (Korean Patent Publication No. 10-2014-0095788, title: Clothing Processing Device), a hot air supply module (4) for heating and circulating air is provided at the top of the tub, and the hot air supply module (4) includes a circulation duct (41, 43, 47) that guides air drawn out from inside the tub (2) to the front surface of the tub (2) (one surface of the tub formed in the direction where the inlet (11) is located), a heat exchanger (45) that exchanges heat with the air flowing along the circulation duct, and a blower (49) located between the heat exchanger (45) and the front surface of the tub to circulate the air inside the tub (2).

[0008] Here, in the case of a clothing processing device according to the prior art, a hot air supply module (4) including a circulation duct (41, 43, 47), a heat exchanger (45), a blower (49), etc. is fixedly installed on the tub (2) at the top of the tub (2).

[0009] Meanwhile, in the case of the tub (2), a drum (3) is provided to be rotatable inside the tub (2), and the drum (3) can be rotated together with the laundry put into it to perform washing / drying of the put-in laundry.

[0010] When the drum (3) described above rotates, vibration may occur in the drum (3) due to the imbalance of the laundry, and the vibration generated in the drum (3) may be transmitted through the tub (2) to a hot air supply module (4) that is fixedly installed on the upper part of the tub (2).

[0011] As described above, in the case of a garment processing device according to the prior art, vibrations generated when the drum (3) rotates can be transmitted to the hot air supply module (4) through the tub (2), and a structure in which such vibrations can be transmitted may have an adverse effect on the durability and performance of the hot air supply module (4).

[0012] Therefore, in order to improve the space utilization of the garment processing device, the arrangement structure of each component placed inside the device is one of the important design considerations, and arranging the components to prevent vibrations generated during drum rotation from being transmitted to other components was also an important design consideration.

[0013] In addition, conventional washing machines with drying functions had limitations in configuration because both the circulation duct and the heat exchanger were located above the tub, and the compressor was located outside the circulation duct.

[0014] In addition, since the inlet and outlet of the circulation duct are located on the same side, air circulation is not easy, which caused a problem of reduced heat exchange efficiency.

[0015] The present invention has been devised to solve the above-mentioned problems, and the purpose of the present invention is to provide a clothing processing device capable of securing space above the tub by placing the compressor below the tub.

[0016] In addition, the present invention aims to provide a clothing processing device capable of increasing heat exchange efficiency by efficiently arranging the circulation ducts.

[0017] In addition, the present invention aims to provide a clothing processing device capable of increasing the flow rate of air passing through a circulation duct.

[0018] In addition, the present invention aims to provide a clothing processing device capable of improving space usage efficiency by improving the arrangement of internal components of the clothing processing device.

[0019] Furthermore, the present invention was devised to solve the aforementioned problems, and aims to provide a clothing processing device capable of improving space utilization efficiency by separately arranging a circulation duct that circulates air inside the tub at the top of the tub.

[0020] Furthermore, the present invention was devised to solve the aforementioned problems, and aims to provide a garment processing device capable of minimizing the transmission of vibrations generated in the drum to the circulation duct by flexibly separating the circulation duct, which circulates air inside the tub, at the top of the tub.

[0021] Furthermore, the present invention was devised to solve the above-mentioned problems, and aims to provide a clothing processing device capable of improving space utilization efficiency by positioning the compressor of the heat exchanger on one side of the lower part of the tub.

[0022] Furthermore, the present invention was devised to solve the above-mentioned problems, and aims to provide a clothing processing device capable of minimizing flow resistance of a circulation duct by improving the flow path structure of a circulation duct that circulates air inside a tub.

[0089] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings.

[0090] In describing the present invention, identical or similar reference numbers are assigned to identical or similar components even in different embodiments, and the description thereof is replaced by the first description. Singular expressions used in this specification include plural expressions unless the context clearly indicates otherwise. Furthermore, in describing the embodiments disclosed in this specification, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions may obscure the essence of the embodiments disclosed in this specification. Additionally, it should be noted that the attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and should not be interpreted as limiting the technical concept disclosed in this specification.

[0091] First, a clothing processing device according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0092] FIG. 1 is a perspective view showing a clothing processing device according to an embodiment of the present invention.

[0093] 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).

[0094] 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).

[0095] 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).

[0096] 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).

[0097] The above front panel (110) may be provided in a plate shape, and a door (112) for opening and closing the opening (111) may be rotatably coupled.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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).

[0102] 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 may be provided as a front fastening hole (122) in the shape of a hole through which a fastening member fastened to the rear of the circulation duct (800) passes.

[0103] 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).

[0104] 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.

[0105] 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).

[0106] 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).

[0107] 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).

[0108] 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.

[0109] 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).

[0110] 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).

[0111] 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).

[0112] The clothing processing device of the present invention may further include a base (600) forming a bottom surface. 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).

[0113] 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).

[0114] 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.

[0115] 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).

[0116] 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 (910, 920) disposed inside the circulation duct (800) and a compressor (940) disposed outside the circulation duct (800) to supply high-temperature refrigerant to the heat exchanger (910, 920).

[0117] The compressor (940) may be positioned below the tub (210). Accordingly, a wider space may be secured between the top of the tub (210) and the side panel (150) for installing the circulation duct (800).

[0118] Accordingly, in the clothing processing device of the present invention, the circulation duct (800) can be arranged to extend 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).

[0119] Additionally, as the compressor (940) is moved from the upper part of the tub (210) to the lower part of the tub (210), the circulation duct (800) can be positioned offset toward one of the two side panels (150) from the top of the tub (210), and the cross-sectional area of ​​the circulation duct (800) can be expanded accordingly.

[0120] Accordingly, the clothing processing device of the present invention can circulate a larger flow of air to the outside of the tub (210) than when the compressor (940) is positioned at the top of the tub (210).

[0121] 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).

[0122] 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.

[0123] 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.

[0124] FIG. 2 is a perspective view showing a circulation duct and a heat exchanger according to an embodiment of the present invention.

[0125] 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).

[0126] 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.

[0127] 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.

[0128] 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) where the circulation duct (800) is offset.

[0129] 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.

[0130] As a result, the distance between the circulation duct (800) and the compressor (940) in the vertical direction can be reduced, and the length of the refrigerant pipe (950) connecting the compressor (940) and the heat exchanger (910, 920) placed inside the circulation duct (800) can be reduced. Accordingly, the refrigerant pipe (950) can be arranged in a straight line in the vertical direction as much as possible, so the flow resistance of the refrigerant is reduced and the heat loss generated in the refrigerant pipe (950) can be minimized.

[0131] 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.

[0132] Accordingly, 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.

[0133] 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.

[0134] The above circulation duct (800) may include a duct body (810) on which the heat exchanger (910, 920) is seated, and a duct cover (820) coupled to the duct body (810) to shield the duct body (810).

[0135] 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).

[0136] 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).

[0137] 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).

[0138] 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).

[0139] 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).

[0140] FIG. 3 is a perspective view showing a base and a back panel according to an embodiment of the present invention.

[0141] 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).

[0142] 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.

[0143] The clothing processing device of the present invention may further include a control unit (not shown) 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).

[0144] 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.

[0145] 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 various sensors of the clothing processing device, current supplied from external power, or 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.

[0146] 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), and may also be provided with a rear fastening hole (162) in the shape of a hole through which a fastening member fastened to the rear of the circulation duct (800) passes.

[0147] FIG. 4 is a perspective view showing a tub according to an embodiment of the present invention.

[0148] The above tub (210) may include a cylindrical tub body (210a) and a tub inlet (213) provided at the front of the tub body (210a) into which clothing can be inserted.

[0149] The diameter of the tub inlet (213) may be smaller than the diameter of the tub body (210a). The circulation part (430) may be coupled and fixed to the outer surface of the tub inlet (213).

[0150] The above tub body (210a) may be formed by dividing it into a front body and a rear body and joining them together, or it may be formed as a single unit.

[0151] The above tub (210) may further include an air outlet (211) provided at the upper rear of the tub body (210a) through which air inside the tub (210) is discharged, and an air inlet (212) provided at the upper part of the tub inlet (213) through which air discharged from the circulation duct (800) is introduced.

[0152] The air outlet (211) may be formed offset to one side from the top of the tub body (210a). By doing so, the air outlet (211) extends from a position lower than the top of the tub body (210a), thereby ensuring sufficient space for the air circulation unit (1000) to be installed.

[0153] The air inlet (212) may be formed at the top of the tub inlet (213).

[0154] 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 (210a) and communicates with the outside, and a connecting pipe (216) that communicates the vent hole (215) with the outside of the cabinet (100).

[0155] FIG. 5 is a perspective view showing a tub and a circulation duct according to an embodiment of the present invention.

[0156] FIG. 5(a) illustrates the tub viewed from the front, and FIG. 5(b) illustrates the tub viewed from the rear.

[0157] 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).

[0158] 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.

[0159] 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).

[0160] 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).

[0161] The above rear connecting part (850) may be provided in a pipe shape or in a zarab type.

[0162] However, the rear connecting part (850) may be positioned between the duct body (810) and the tub body (210a). 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).

[0163] 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).

[0164] 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.

[0165] 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.

[0166] FIG. 6 is a simplified diagram showing the positional relationship between a tub and a circulation duct according to an embodiment of the present invention.

[0167] The above circulation duct (800) is provided with a resin-based material, and the heat exchanger (910, 920) 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 (910, 920) 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), the above circulation duct (800) and the tub (210) may collide with each other or, in severe cases, be damaged. Therefore, the above circulation duct (800) may be installed inside the cabinet (100) while maintaining a certain distance from the tub (210).

[0168] 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).

[0169] FIG. 7 is a perspective view showing a duct body according to an embodiment of the present invention.

[0170] 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 (910, 920), 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 (813) and the installation duct (814) together may be named as a moving duct (813, 814) that forms a path for air passing through the inlet duct (811).

[0171] 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.

[0172] 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.

[0173] The rear connecting part (850) may have one end or the lower end connected to or in contact with the air inlet (212), and the other end or the upper end connected to or in contact with the inlet duct (811).

[0174] The above fan housing (812) may be provided in a circular or spiral shape. The above fan housing (812) may be provided larger than the diameter or area of ​​the inlet duct (811) to secure space for the installation of the air circulation unit (1000). The air circulation unit (1000) may be installed in the above fan housing (812) to draw in air from the tub (210) and supply it to the heat exchanger.

[0175] 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.

[0176] 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.

[0177] The above installation duct (814) is provided with a width greater than that of the front end of the above connection duct (813) so that the heat exchanger (910, 920) can be seated thereon. The above installation duct (814) can form a space in which the evaporator (910) and condenser (920), which will be described later, are seated.

[0178] 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).

[0179] 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.

[0180] 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).

[0181] 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).

[0182] 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).

[0183] 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).

[0184] 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).

[0185] Additionally, the front fixing part (861) may be provided with a protruding front fastening boss (862) that protrudes from the front of the exhaust duct (815). The front fastening boss (862) may be provided in multiple numbers and may be 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).

[0186] 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).

[0187] Additionally, the rear fixing part (862) may be provided with a rear fastening boss (864) having a projection shape that protrudes from the rear of the fan housing (812). The rear fastening boss (864) may be provided in multiple numbers and may be 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).

[0188] Accordingly, the circulation duct (800) can be fixedly supported on the cabinet (100) relatively compared to the tub (210) being flexibly supported by the support member (500) with respect to the base (600).

[0189] That is, the circulation duct (800) is fixed to the cabinet (100), and even if the tub (210) moves due to vibrations generated by the rotation of the drum (220), the vibrations of the tub (210) are reduced at the front connection part (840) and the rear connection part (850), so that the circulation duct (800) can be prevented from moving.

[0190] FIG. 8 is a perspective view showing a communication structure between a duct body and a tub according to an embodiment of the present invention.

[0191] The above duct body (810) can be extended from the rear to the front of the tub.

[0192] 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 the upper part of the air outlet (211) and the upper part of the air inlet (212) in the height direction.

[0193] 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).

[0194] However, since the air outlet (211) extends upward from the tub body (210a), 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).

[0195] Accordingly, the bracket (830) may be provided to be seated on the upper part of the tub body (210a) 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 (210a) and the lower end of the rear connecting part (850) may be brought into close contact with the air outlet (211).

[0196] 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).

[0197] The above bracket (830) may include a bracket body (831) that is seated on the tub body (210a) 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 (210a), and the coupling hole may be positioned spaced apart 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 (210a).

[0198] FIG. 9 is a partial cross-sectional perspective view showing the flow path structure of a circulation duct according to an embodiment of the present invention.

[0199] The above air circulation unit (1000) can be positioned above the inlet duct (811).

[0200] 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 (210a), a fan motor (1200) that is seated 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).

[0201] 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).

[0202] 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.

[0203] 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).

[0204] 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).

[0205] This process is performed continuously so that the clothing contained in the drum (220) can be dried.

[0206] FIG. 10 is a perspective view showing the internal structure of a circulation duct according to an embodiment of the present invention.

[0207] 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 (814). 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.

[0208] 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.

[0209] 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).

[0210] 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.

[0211] 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).

[0212] 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).

[0213] 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).

[0214] 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).

[0215] FIG. 11 is a perspective view showing a structure for supplying water to a circulation duct according to an embodiment of the present invention.

[0216] The nozzle part (3000) can be positioned between the lower part of the duct cover (820) and the evaporator (910).

[0217] 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).

[0218] 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 direction of the nozzle section (3000).

[0219] FIG. 12 is a perspective view showing a front view with the front panel removed according to an embodiment of the present invention.

[0220] Referring to FIG. 12, the tub inlet (213) is provided at the front of the tub (210), and the air inlet (212) may be provided at the upper center of the tub inlet (213).

[0221] Meanwhile, the air outlet (211) may be provided offset to one side from the rear of the tub (210).

[0222] Additionally, the circulation duct (800) may be provided above the tub (210) and fixed to the installation panel (120). The circulation duct may be provided above the tub, offset to one side where the air outlet (212) is provided, and the circulation duct may be provided to be longer than half the width of the tub. That is, the circulation duct may be provided to encroach upon the center of the tub from one side of the tub.

[0223] Meanwhile, the air inlet (212) and the exhaust duct (815) may be connected by a front connection part (840) to be described later, and the air outlet (211) and the fan housing (812) may be connected by a rear connection part (850) to be described later.

[0224] Meanwhile, referring to FIG. 12, the installation duct (814) on which the heat exchanger (910, 920) is installed may be positioned so as to pass through the center of the tub (210) from one side of the tub. That is, the width (D2) of the installation duct may be provided to be longer than half the width (D1) of the tub. That is, the exhaust duct (815) may be provided so as to overlap at least a part with the center of the air inlet (212) and the tub inlet (213).

[0225] By doing so, the flow rate of air passing through the above-mentioned moving ducts (813, 814) can be secured, thereby improving drying efficiency.

[0226] FIG. 13 is a partial perspective view showing the arrangement of an exhaust duct and an air inlet according to an embodiment of the present invention.

[0227] The air inlet (212) may be provided at the top center of the tub inlet (213), and the exhaust duct (815) may be arranged so as to overlap at least a portion with the air inlet.

[0228] As a result, the airflow path of the air flowing from the exhaust duct to the air inlet is formed to be close to a straight line, thereby minimizing flow resistance.

[0229] FIG. 14 is a partial perspective view showing the arrangement of an inlet duct and an air outlet according to an embodiment of the present invention.

[0230] The above-mentioned tub (210) includes an air outlet (211) positioned to one side at the rear of the tub and through which air inside the tub is discharged, and the air outlet may be positioned so as to overlap at least a portion with the inlet duct (811).

[0231] Thus, the airflow path from the air outlet (211) to the inlet duct (811) can be formed to be close to a straight line, thereby minimizing flow resistance.

[0232] FIG. 15 is a perspective view showing the location where a circulation duct and a heat exchanger are arranged according to an embodiment of the present invention.

[0233] The above circulation duct (800) may be configured such that the inlet duct (811) is positioned at the rear and the discharge duct (815) is positioned at the front, and the moving ducts (813, 814) are configured to connect the inlet duct and the discharge duct, so as to be positioned in the front-rear direction above the tub. Additionally, since the compressor is located below the tub (210), the circulation duct may be positioned in the front-rear direction above the tub and may be positioned offset toward one side of the cabinet (100).

[0234] Meanwhile, the air circulation unit (1000) may be positioned at the rear of the circulation duct (800), the fan housing (812) may be provided inside the duct body (810), and the fan motor (1200) may be coupled to the upper surface of the duct cover (820) so that the rotation shaft (1300) passes through the duct cover (520) and is coupled to the impeller (1100). That is, the rotation shaft may be provided to be perpendicular to the ground. Thus, the impeller can rotate to move air to the rear of the circulation duct. Referring to FIG. 12, the impeller can rotate counterclockwise to move air to the rear of the circulation duct.

[0235] Meanwhile, the refrigerant pipe (950) may be positioned such that at least a portion of it is spaced apart from the tub (210) and does not overlap with the tub in the front-rear direction. That is, the compressor (940) is provided at the rear of one side of the base body (610), and the refrigerant pipe may extend from the compressor upward along the side panel of the cabinet (100) to a height where the heat exchanger (900) is positioned, and then extend from the rear to the front toward the heat exchanger.

[0236] Meanwhile, the air inlet (212) may be provided to be positioned in the center of the tub inlet (213). Since the air outlet (211) is provided offset to one side of the tub (210), the air discharged to one side of the tub is introduced into the center of the tub and circulated, so the hot air can be evenly distributed, thereby improving drying efficiency.

[0237] Meanwhile, the compressor (940) may be positioned below the tub (210) and spaced apart so that at least a portion does not overlap with the circulation duct (800) in the vertical direction. That is, the compressor may be positioned closer to one side of the cabinet than to the circulation duct.

[0238] In other words, since the compressor (940) is exposed to the outside of the tub (210), the refrigerant pipe (950) extending from the compressor can extend vertically upward between one side of the cabinet and the tub without bypassing the tub, thus making it easy to connect the compressor, the evaporator (910), and the condenser (920).

[0239] The fan housing (812) and the impeller (1100) are positioned above the inlet duct, and the lower surfaces of the fan housing and the impeller are located below the lower surfaces of the evaporator (910), the condenser (920), and the installation duct (814), while the upper surface of the fan housing may be located above the upper surfaces of the evaporator (910), the condenser (920), and the installation duct. Since there is a height difference between the upper surfaces of the fan housing and the installation duct, the refrigerant pipe can extend from above the fan housing toward the installation duct without bypassing it. This simplifies the flow path of the refrigerant pipe, thereby improving the efficiency of the refrigerant.

[0240] FIG. 16 is a top view of a circulation duct according to an embodiment of the present invention.

[0241] Referring to FIG. 16, the fan motor (1200) may be provided with a width smaller than that of the fan housing (812), so that the refrigerant pipe may be extended from above the fan housing to a space where the fan motor is not provided. In other words, the refrigerant pipe may be arranged to overlap with the fan motor in the left-right direction and extend to pass through one side of the fan motor.

[0242] That is, the refrigerant pipe (950) can be extended vertically upward from the compressor (940) and then extended forward at a height corresponding to the upper part of the evaporator (910) (a position higher than the impeller and the fan housing), so the flow path of the refrigerant pipe can be simplified, thereby increasing the efficiency of the refrigerant.

[0243] Additionally, the center of the movable duct (813, 814) may be positioned closer to the center of the tub inlet (213) than to the center of the fan housing (812). That is, the distance (D3) from the center of the movable duct to one side of the cabinet may be longer than the distance (D4) from the center of the fan housing to one side of the cabinet. By doing so, the airflow path discharged from the tub can be made streamlined, thereby reducing flow resistance.

[0244] FIG. 17 is an exemplary diagram showing an embodiment of a coupling structure in which a bracket according to an embodiment of the present invention is coupled to the top of an air outlet.

[0245] Referring to FIG. 17, the bracket (830) may include a fastening hole (8316) that penetrates the bracket body (831) and is coupled to the upper surface of the tub.

[0246] As described above, the bracket (830) is provided with at least a portion between the tub (210) and the circulation duct (800), and the bracket body (831) may be provided to extend to a position where the fastening hole (8316) is positioned so as not to overlap with the circulation duct in the vertical direction. For example, as shown in FIG. 11, the bracket body may be extended in a rod shape, and the fastening hole may be provided at the end. Thus, since the fastening hole is exposed, the worker can easily install it and replace or repair the bracket without removing the circulation duct (800).

[0247] Meanwhile, the bracket body (831) may extend into multiple branches from the coupling hole (8316), and the fastening holes may be provided at the ends of the multiple branches, so that the fastening holes may be provided in multiple numbers. By doing so, the coupling strength between the tub (210) and the bracket (830) can be improved.

[0248] FIGS. 18 and 19 are exemplary drawings showing another embodiment of a coupling structure in which a bracket according to one embodiment of the present invention is coupled to the upper part of an air outlet, illustrating an embodiment in which the bracket is provided below a circulation duct.

[0249] Referring to FIGS. 18 and 19, the duct body (810) may include a through hole (817) that penetrates in the thickness direction to disperse the flow path, and the bracket body (831) may be extended so that the fastening hole (8316) is positioned at a location corresponding to the through hole.

[0250] As shown in FIG. 17, the bracket body (831) may be extended in the shape of a rod so that the fastening hole (8316) is positioned at a location corresponding to the through hole (817), but as shown in FIG. 15 and FIG. 16, it may be extended in the shape of a plate so that the fastening hole is positioned at a location corresponding to the through hole. Since the fastening hole is exposed to the outside by the through hole, it may be easy for the worker to combine the bracket (830) and the tub (210).

[0251] Meanwhile, the above-mentioned through hole (817) may be provided in an area where the flow velocity inside the circulation duct is concentrated so as not to obstruct the flow inside the circulation duct (800).

[0252] Referring to FIG. 18, the impeller (1100) rotates counterclockwise to move air to the rear of the circulation duct (800), and the air can flow counterclockwise to move to the connecting duct. In this case, since the flow velocity is concentrated on the left side of the impeller (1100), the through hole (817) may be provided spaced apart from the impeller to the left. Since the flow velocity is distributed in the area where the flow velocity is concentrated by the through hole, the flow of air can be maintained smoothly.

[0253] Additionally, the through hole (817) may be provided so that it extends in the longitudinal direction of the flow path and its outer surface is formed in a streamlined shape. By doing so, the flow path resistance is reduced, allowing the air flow to be maintained smoothly, thereby preventing a decrease in thermal efficiency caused by the through hole.

[0254] Meanwhile, the above-mentioned through hole (817) can be provided by utilizing a section with low flow velocity.

[0255] Referring to FIG. 18, the flow path adjacent to the impeller (1100) is formed as a curved surface, and a vortex can be generated by the curved surface. Since the flow velocity is low in the area where the vortex is generated, if the through hole (817) is provided in this area, the fastening hole (8316) can be exposed without obstructing the flow of air.

[0256] FIG. 20 is an illustrative diagram showing another embodiment of a coupling structure in which a bracket according to one embodiment of the present invention is coupled to the top of an air outlet.

[0257] Referring to FIG. 20, the bracket (830) may include a coupling hole (832) that is coupled to the lower end of the rear connecting part and is configured to communicate with the air outlet and the rear connecting part, a bracket body (831) that extends outwardly from the outer surface of the coupling hole, and a support part (880) that is fixed to the tub (210) to support the bracket. Additionally, the bracket may include a fixing part (8317) configured to combine the bracket and the support part.

[0258] The coupling hole (832) may be provided as a ring having a shape corresponding to the cross-section of the air outlet (211), the bracket body (831) may be provided as a plate shape protruding outward from the outer surface of the coupling hole, and the fixing part (8317) may include a fixing rib provided in a rib shape protruding outward from the bracket body.

[0259] Meanwhile, the circulation duct (800), the rear connecting part (850), and the bracket (830) can be provided as a single unit. Thus, during the assembly process, the circulation duct can be fixed to the cabinet (100) and the bracket can be connected to the support part (880) to complete the assembly, thereby making the work easier.

[0260] The bracket (830) may be coupled to the support member (880) so that the rear connecting member (850) communicates with the circulation duct (800) and the air outlet (211).

[0261] The support member (880) can fix the position so that the bracket (830) is coupled to the tub (210) at an accurate position. When the support member fixes the position of the bracket, the bracket and the tub can be coupled by a fastening member.

[0262] Referring to FIG. 20, the support member (880) may be provided on the outer surface of the tub (210). The support member is coupled to the outer surface of the tub at a position spaced apart from the air outlet (211), and the bracket may be inserted into the support member and coupled between the air outlet and the support member.

[0263] The above fixing part (8317) may include a fixing rib (83171) in the form of a projection protruding outward from the bracket body (831), and the above supporting part (880) may include a supporting body (881) fixed to the tub, and a guide groove (882) provided in the shape of a groove protruding inward from the supporting body so that the bracket (830) rotates and the fixing rib can move a certain distance.

[0264] The guide groove (882) is provided with a length of a certain distance on the inner side of the support body (881), and when the bracket (830) rotates and the fixing rib (83171) moves a certain distance along the guide groove, the movement is blocked so that the bracket can no longer rotate, and the bracket can be positioned in a direction to be coupled to the tub (210).

[0265] That is, the bracket body (831) includes the fastening hole (8316) which is coupled to the tub (210), and the tub may include a tub fastening hole (217) which is provided in a shape corresponding to the fastening hole and coupled to the fastening hole by a fastening member, and the bracket may rotate so that the fastening hole is positioned at a position corresponding to the tub fastening hole by means of the fixing rib (8317) and the guide groove (882).

The fixing member (8317) includes a bent rib (83172) that is provided on the bracket body (831) and is bent to engage with the guide rib. The bent rib is configured so that the bracket body is seated on the support body and rotates to engage with the guide rib, thereby allowing the bracket to be fixed to the support member. That is, since the support body can be configured to be coupled with the tub, the bracket and the tub can be coupled.

[0268] The guide ribs (883) and the bending ribs (83172) may be provided in multiple numbers spaced apart from each other, and the spacing between the guide ribs and the spacing between the bending ribs may be provided to be the same.

For example, the coupling rib and the support coupling body can be coupled by a fastening member.

[0271] Referring to FIG. 22, the support groove (884) is provided on one side of the support coupling body (885), the bracket (830) is inserted into the support groove from the other side, and the coupling rib (83172) and the support coupling body (885) can be joined by a fastening member.

[0272] Hereinafter, a circulation duct according to an embodiment of the present invention will be described in detail with reference to FIGS. 23 to 25.

[0273] FIG. 23 is an exemplary diagram showing the connection state of a circulation duct of a clothing processing device according to an embodiment of the present invention, and FIG. 24 is an exploded perspective view showing the connection of a duct body and a duct cover of a circulation duct according to an embodiment of the present invention.

[0274] As illustrated in FIGS. 23 and 24, the circulation duct (800) can be fixed by being fastened to the front and rear of the installation panel (120) and the rear panel (160) of the cabinet (100), respectively.

[0275] Here, a front fixing part (861) is formed at the front of the duct body (810) constituting the circulation duct (800) to be fastened to a front fastening hole (122) formed in the panel installation part (121) of the installation panel (120), and a rear fixing part (863) is formed at the rear of the duct body (810) to be fastened to the rear fastening part of the rear panel (160).

[0276] Accordingly, the duct body (810) can be fixedly fastened to a separate fastening member between the installation panel and the back panel. Additionally, the duct cover (820) can be detachably coupled to the upper part of the duct body to form the circulation duct (800).

[0277] As described above, the 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).

[0278] Here, the inlet duct (811), the fan housing (812), the installation duct (814), and the exhaust duct (815) forming the duct body (810) can be formed integrally by injection molding of the same material.

[0279] Additionally, a sealing groove (894) may be extended and formed on the upper outer surface of the duct body (810) to which a sealing member (not shown) is inserted to form a seal with the duct cover (820) when fastened to the duct cover (820). Meanwhile, the sealing member may be formed along the shape of the outer surface of the duct body (810).

[0280] That is, the sealing groove (894) can be formed along the outer surface of the inlet duct (811), the fan housing (812), the installation duct (814), and the discharge duct (815), and across the entire outer surface of the duct body (810).

[0281] Meanwhile, the duct cover (820) may include a housing cover (821) that shields the fan housing (812), a connection cover (822) that shields the connection duct (813), an installation cover (823) that shields the installation duct (814), and an exhaust cover (824) that shields the exhaust duct (815).

[0282] Here, the housing cover (821), the connecting cover (822), the installation cover (823), and the discharge cover (824) forming the duct cover (820) can be formed integrally by injection molding of the same material.

[0283] A sealing projection (892) may be extended and formed on the lower outer surface of the duct cover (820) to press the sealing member provided in the duct body (810) when connected to the duct body (810). The sealing projection (892) may be formed to extend in correspondence with the shape of the sealing groove (894) formed in the duct body (810).

[0284] Here, the sealing projection (892) may be formed along the outer surface of the housing cover (821), the connecting cover (822), the installation cover (823), and the discharge cover (824) that form the duct cover (820).

[0285] Accordingly, when the duct cover (820) is fastened to the duct body (810), the sealing projection (892) of the duct cover (820) presses the sealing member inserted into the sealing groove (894) of the duct body (810), thereby forming an airtight seal between the duct cover (820) and the duct body (810).

[0286] Here, the duct body (810) is provided so as to be fixedly fastened with the installation panel (120) and the rear panel (160) in contact at the front and rear, respectively, and the duct cover (820) may be detachably provided to the duct body (810) by a separate fastening structure.

[0287] That is, the duct cover (820) must be detachably provided to the duct body (810) for the convenience of installation and maintenance of the air circulation unit (1000) and the heat exchanger, etc., installed in the duct body (810).

[0288] Meanwhile, in the case of the above duct body (810), the installation panel (120) and the back panel (160) are fixedly connected in a contact state, so the connection structure of the duct cover (820) connected to the above duct body (810) is necessarily limited.

[0289] The connection between the duct body (810) and the duct cover (820) may be provided with an outer connection part (870) formed on the outer surface of the duct body (810) and the duct cover (820), and an inner connection part (880) formed through the duct body (810) and the duct cover (820) at the front of the duct body (810) and the duct cover (820).

[0290] The outer fastening portion (870) may include a locking hook (874) formed on the outer surface of the duct body (810) and a locking projection (872) elastically extended toward the locking hook (874) on the outer surface of the duct cover (820) corresponding to the position of the locking hook (874).

[0291] Additionally, the internal fastening portion (880) may include an upper fastening portion (880a) formed on the inner side of the discharge cover (824) of the duct cover (820), and a lower fastening portion (880b) formed on the inner side of the discharge duct (824) of the duct body (810) and inserted into the upper fastening portion (880a).

[0292] Meanwhile, as described above, the circulation duct (800) may have an air passage formed from one side of the upper rear of the tub (210) to the other side of the front, and according to this air passage, the air passage from the air circulation unit (1000) to the exhaust duct (815) is not formed uniformly and must be formed eccentrically.

[0293] Below, the flow path structure of the above-mentioned circulation duct (800) will be explained in detail with reference to FIG. 25.

[0294] FIG. 25 is a simplified diagram showing the flow path structure of a circulation duct according to an embodiment of the present invention.

[0295] Here, FIG. 25 schematically illustrates a plan view of the duct body (810) among the structures of the circulation duct (800), and the duct cover (820) may be formed to correspond to the shape of the duct body (810). That is, the air flow path of the circulation duct (800) may be formed by the combination of the duct body (810) and the duct cover (820), and the duct body and the duct cover may form the same flow path. Therefore, in describing the air flow path of the circulation duct (800), the duct body (810) will be described in detail, and the description of the duct cover (820) will be omitted.

[0296] As illustrated in FIG. 25, the duct body (810) may include a fan housing (812) in which the air circulation unit (1000) is accommodated, a connecting duct (813) extending forward from the fan housing (812), an installation duct (814) extending forward from the connecting duct (813) in which a heat exchanger (910, 920) is installed, and an exhaust duct (815) extending forward or downward from the installation duct (814) to discharge air to the air inlet (212).

[0297] Meanwhile, the fan housing (812) is formed in a shape that surrounds the air circulation unit (1000), and its outer surface may extend toward the connecting duct (813) in a shape having an Archimides curve.

[0298] That is, the outer surface of the fan housing (812) expands radially with a constant expansion angle according to the Archimides curve function, with the radius (R1-R2) gradually expanding based on the center of the fan housing (812) (C0, i.e., the center of the air circulation unit (1000)), and the center is separated to form a cutoff point (P).

[0299] Accordingly, the outlet side of the fan housing (812) is formed so that the connecting duct (813) is connected based on the cutoff point (P), and the connecting duct (813) can be formed to be connected from the cutoff point (P) and the outer wall (D4) corresponding parallel to the cutoff point (P).

[0300] Meanwhile, one side of the connecting duct (813) may be extended in a manner different from the outer surface of the fan housing (812) being extended by an Archimedes curve function at the outer wall (D4) corresponding to the cutoff point (P).

[0301] That is, the outer wall of the fan housing (812) may be formed by continuously connecting radii (R1-R2) having a center facing the center of the fan housing (812), but the outer wall (D4) of the connecting duct (813) may have a radius (R3) having a center facing the radius (R1-D2) of the fan housing (812).

[0302] Meanwhile, the other side of the connecting duct (813) may have an outer wall (D3) connected to the cutoff point (P), and the other outer wall (D3) of the connecting duct (813) may be formed in a straight line shape, unlike the one outer wall (D4) of the connecting duct (813).

[0303] That is, the above connecting duct (813) may have a curved outer wall (D4) on one side and a straight outer wall (D3) on the other side, and may expand the airflow path of the air moved by the blower fan (1000) in the above fan housing (812).

[0304] Additionally, the discharge port (D1) of the fan housing (812) to which the connecting duct (813) is connected may be formed based on the cut-off point (P), and the discharge port (D2) of the connecting duct (813) to which the installation duct (814) is connected may be formed by one outer wall (D4) and the other outer wall (D3) of the connecting duct (813).

[0305] Meanwhile, in the case of air discharged from the discharge port (D1) of the fan housing (812), it is discharged to the discharge port (D1) of the fan housing (812) by the centrifugal force of the blower fan (100), and the difference in length between one outer wall (D4) and the other outer wall (D3) of the connecting duct (813) affects the air flow velocity, so the air flow velocity and density passing through the connecting duct (813) may become unstable.

[0306] That is, in the case of air discharged from the discharge port (D1) of the fan housing (812), the air flow velocity on one side outer wall (D4) of the connecting duct (813) is formed faster than the air flow velocity on the other side outer wall (D3) of the connecting duct (813) due to the centrifugal force of the blower fan (1000).

[0307] Accordingly, by changing the shape and length of the outer wall (D4) on one side and the outer wall (D3) on the other side of the connecting duct (813), the air flow velocity and density of the air passing through the connecting duct can be stabilized.

[0308] Preferably, the length of one side outer wall (D4) of the connecting duct (813) may be formed to be equal to or longer than the length of the other side outer wall (D3) of the connecting duct (813). Accordingly, by forming the length of one side outer wall (D4) of the connecting duct (813) to be equal to or longer than the length of the other side outer wall (D3) of the connecting duct (813), the air flow velocity can be stabilized.

[0309] Alternatively, the shape of one side outer wall (D4) of the connecting duct (813) may be formed to have a radius (R3) so as to be recessed into the side of the connecting duct, and the other side outer wall (D3) of the connecting duct (813) may be formed in a straight shape to stabilize the air flow velocity.

[0310] Meanwhile, the discharge port (D1) of the fan housing (812) and the discharge port (D2) of the connecting duct (813) may have a ratio of 4:6. That is, air passing through the discharge port (D1) of the fan housing (812) moves to the installation duct (814) through the discharge port of the connecting duct (813), and if the size of the discharge port (D2) of the connecting duct (813) is relatively smaller than the discharge port of the fan housing (812), instability in the flow velocity and a decrease in flow velocity of the air passing through the connecting duct (813) occur.

[0311] Accordingly, by forming the discharge port (D1) of the fan housing (812) and the discharge port (D2) of the connecting duct (813) to have a ratio of 4:6, the airflow velocity passing through the connecting duct (813) can be stabilized and the velocity can be prevented at the same time.

[0312] Additionally, the shape and length of one outer wall (D4) and the other outer wall (D3) of the connecting duct (813) may be formed differently, and in this case, the center (C1) of the discharge port (D1) of the fan housing (812) and the center (C2) of the discharge port (D2) of the connecting duct may be formed to be spaced apart from each other by a certain distance (G0).

[0313] As described above, preferred embodiments of the present invention have been described in detail; however, a person skilled in the art to which the present invention pertains will be able to modify the present invention in various ways without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, future modifications to the embodiments of the present invention will not depart from the technology of the present invention.
