Description

TECHNICAL FIELD

[0001] The present application relates to a laundry treating apparatus. In more detail, the present application relates to a laundry treating apparatus including a driving part directly connected with a drum accommodating laundry and capable of rotating the drum. BACKGROUND

[0002] The laundry treating apparatus is an apparatus capable of removing dust or impurities attached to laundry by applying physical force to the laundry, including a washing machine, a dryer, a laundry care apparatus, etc.

[0003] The washing machine performs a washing program capable of separating and removing impurities on laundry by supplying water and a detergent to the laundry.

[0004] The dryer is classified into an exhaust type dryer or a circulation type dryer, which commonly performs a drying program by generating hot air of high temperature through a heater and blowing the hot air to laundry to remove moisture contained in the laundry.

[0005] In recent years, the dryer is configured to omit a structure of supplying water to the inside of laundry or draining water, and also to omit an outer tub accommodating water inside a cabinet, thereby being capable of collectively performing a drying program. Accordingly, the dryer has an advantage of not only simplifying the structure of the inside of the dryer, but also being capable of improving drying efficiency by directly supplying hot air to a drum accommodating laundry.

[0006] Such a dryer can include a drum accommodating the laundry, a hot air supply part supplying hot air to the drum, and a driving part rotating the drum. Thereby, the dryer dries the laundry accommodated in the drum by supplying hot air to the inside of the drum, and is capable of uniformly exposing the surface of the laundry to the hot air by rotating the drum. As a result, the entire surface of the laundry can be uniformly contacted with the hot air to complete drying.

[0007] On the other hand, the driving part needs to be fixed inside the cabinet in order to rotate the drum. Further, in the case where the driving part is configured to rotate a rotating shaft combined with the drum, the driving part needs to be combined flush with the rotating shaft. However, since there is no outer tub fixed inside the cabinet in the dryer, there is a problem that the driving part cannot be fixed to the outer tub as in the washing machine.

[0008] In order to solve the above problem, a dryer fixing the driving part to the back of the cabinet has been proposed (refer to Japanese Laid-Open Patent Publication JPS55-081914A, Japanese Laid-Open Patent Publication JPS55-115455A, Japanese Laid-Open Patent Publication JPS57-063724A, Japanese Laid-Open Patent Publication JPS57-124674A).

[0009] Figure 1 A structure of a conventional dryer in which the driving part is combined at the back of the cabinet is shown.

[0010] Such a dryer can include a cabinet 1 forming an appearance, a drum 2 disposed inside the cabinet 1 in a rotatable manner, accommodating laundry, and a driving part 3 configured to rotate the drum 2.

[0011] The driving part 3 can be disposed at the back of the drum 2 and rotate the drum 2, and can be combined and fixed to a back panel 11 forming the back of the cabinet 1. Thereby, the driving part 3 can be fixed to the cabinet 1 and rotate the drum 2.

[0012] The aforementioned driving part 3 of the conventional dryer can collectively include a stator 31 fixed to the back panel 11, a rotor 32 rotated by the stator 31, and a rotating shaft 33 combined with the rotor 32 and rotating the drum 2, and include a reducer 37 configured to increase torque by reducing rpm of the rotating shaft 33 and rotate the drum 2.

[0013] In addition, the conventional dryer collectively includes a fixing part 4 fixing the driving part 3 to the back panel 11. The fixing part 4 can include one or more of a first fixing part 41 fixing the stator 31 to the back panel 11 and a second fixing part 42 fixing the rotating shaft 33 to the back panel 11. Thereby, the conventional dryer can stably rotate the drum 2 by disposing the rotating shaft 33 combined with the drum 2 and the driving part 3 flush.

[0014] However, since the back panel 11 of the cabinet is composed of a thin steel plate, it can be easily deformed or vibrated even by a relatively small external force. Further, the back panel 11 not only bears a load of the driving part 3, but also bears a load of the drum 2 through the rotating shaft 33, and thus can not easily maintain its shape.

[0015] In addition, in a case where laundry is eccentrically located inside the drum 2 or repeatedly falls into the drum 2 during rotation, an external force can be repeatedly transmitted to the back panel 11, thereby causing the back panel 11 to vibrate.

[0016] In the case where the back panel 11 is temporarily bent or deformed due to vibration or external force transmission to the back panel 11, a problem that the rotation shaft 33 connecting the driving part 3 and the drum 2 is misaligned can occur. Thus, there is a problem that unnecessary vibration or noise can be generated in the driving part 3, or even in a serious case, the rotation shaft 33 can be damaged. In addition, there is also a problem that unnecessary noise is generated in the process in which the back panel 11 is bent or deformed.

[0017] In addition, in the process in which the back panel 11 vibrates, a problem that the interval between the rotor 32 and the stator 31 is temporarily changed, causing the rotor 32 to collide with the stator 31 or generating unnecessary vibration and noise can occur.

[0018] Further, in the case where the driving part 3 further includes the decelerator 37, the rotation shaft 33 combined with the decelerator 37 and the deceleration shaft 33a connected from the decelerator 37 to the drum 2 are separated from each other. At this time, since the decelerator 37 is supported to the back panel 11 through the stator 31 or the rotation shaft 33, even if the back panel 11 is slightly deformed, a problem that the deceleration shaft 33a and the rotation shaft 33 are misaligned can occur.

[0019] In other words, the amount of change in the position of the deceleration shaft 33a connected to the drum 2 can be smaller than that of the rotation shaft 33 combined with the driving part 3 due to the load of the drum 2. Thus, in the case where the back panel 11 is temporarily bent or deformed, the inclination degrees of the rotation shaft 33 and the deceleration shaft 33a will be different, causing the rotation shaft 33 and the deceleration shaft 33a to be misalignedly disposed.

[0020] Thus, in the existing laundry treating apparatus, the rotation shaft 33 and the deceleration shaft 33a will be misaligned every time the driving part 3 is operated, which not only fails to ensure the reliability of the decelerator 37, but also has a risk that the decelerator 37 is damaged.

[0021] Thus, the existing dryer is disclosed only in the patent document, and has a fundamental limitation that it cannot be adopted as an actual product and introduced into the market.

[0022] In addition, such an existing dryer has a problem that no explicit suggestion or structure is suggested for a flow path in which air of the drum is moved to a base located at a lower position than the drum, or how to treat condensed water condensed in the flow path. Thus, there is a problem that no suggestion is provided for how to change and use the structure of the base when the position of the driving part is changed. SUMMARY

[0095] Figure 3 An appearance of a laundry treating apparatus of the present application is illustrated.

[0096] The laundry treating apparatus of an embodiment of the present application can include a cabinet 100 forming an appearance.

[0097] The cabinet 100 can include a front panel 110 forming a front surface of the laundry treating apparatus, an upper panel 150 forming a top surface of the laundry treating apparatus, and side panels 140 forming side surfaces of the laundry treating apparatus. The side panels 140 can include a left side panel 141 forming a left side surface. The front panel 110 can be provided with an opening portion 111 configured to communicate with an inside of the cabinet 100, and a door 130 rotatably coupled to the cabinet 100 to open and close the opening portion 111.

[0098] The front panel 110 can be provided with an operation panel 117. The operation panel 117 can be provided with an input portion 118 that receives a control command from a user and a display portion 119 that outputs information such as a control command that the user can select. The control command can include a drying course or a drying option that can execute a series of drying programs. The cabinet 100 can be provided with a control box (refer to Figure 12 ) that controls internal structures to execute the control command input through the input portion 118. The control box can be connected with structures inside the laundry treating apparatus and control the corresponding structures to execute the input command.

[0099] The input portion 118 can include a power supply request portion that requests power supply to the laundry treating apparatus, a course input portion that can select a course desired by the user among a plurality of courses, and a running request portion that requests start of the course selected by the user.

[0100] The display portion 119 can include at least one of a display panel that can output text and graphics, and a speaker that can output a voice signal or sound.

[0101] On the other hand, the laundry treating apparatus of the present application can include a water storage tank 120 configured to separately store moisture generated in a course of drying laundry. The water storage tank 120 can include a handle configured to be able to be drawn out to the outside from one side of the front panel 110. The water storage tank 120 can be configured to collect condensed water generated in a drying program. Thus, the user can draw out the water storage tank 120 from the cabinet 100 and remove the condensed water, and then install it to the cabinet 100 again. Thus, the laundry treating apparatus of the present application can also be configured in a place where a sewer or the like is not installed.

[0102] On the other hand, the water storage tank 120 can be configured at an upper portion of the door 130. Thus, the user can bend less when drawing out the water storage tank 120 from the front panel 110, thereby having an effect of improving convenience of the user.

[0103] Figure 4 The inside of the laundry treating apparatus of the present application is briefly shown.

[0104] The laundry treating apparatus of the present application can include a drum 200 received inside the cabinet 100 to receive laundry, a driving part to rotate the drum 200, a heat exchanging part 900 configured to supply hot air to the drum 200, and a base 800 in which a circulation flow path part 820 is provided. The circulation flow path part 820 is configured to communicate with the drum 200. Air discharged from the drum 200 can be supplied to the circulation flow path part 820. In addition, air discharged from the circulation flow path part 820 can be re-supplied to the drum 200.

[0105] The driving part can include a motor part 500 to provide power to rotate the drum 200. The driving part can be directly connected to the drum 200 to rotate the drum 200. For example, the driving part can be configured in a direct drive (DD) type. Thereby, the driving part can omit a structure such as a belt and a pulley to directly rotate the drum 200, thereby controlling a rotational direction of the drum 200 or a rotational speed of the drum 200.

[0106] The motor part 500 can rotate at a high speed RPM. For example, it can rotate at a speed much higher than an RPM at which laundry inside the drum 200 can rotate in a state of being attached to an inner wall of the drum 200.

[0107] However, if laundry inside the drum 200 continuously rotates in a state of being attached to the inner wall of the drum 200, there is a problem in that drying efficiency is reduced since a portion attached to the inner wall of the drum is not exposed to hot air.

[0108] If the rotor 520 is rotated at a low speed RPM to tumble or agitate laundry inside the drum 200 without being attached to the inner wall of the drum 200, there is a problem in that output or torque that the driving part can generate can not be normally used.

[0109] Therefore, the driving part of the laundry treating apparatus of the present application can further include a speed reducer 600 to increase torque in a case where the maximum output of the motor part 500 is used by reducing an RPM.

[0110] In addition, the driving part can include a drum rotating shaft 6341 connected to the drum 200 and rotating the drum 200.

[0111] The drum 200 can be configured in a cylindrical shape and can accommodate laundry. In addition, unlike a drum for washing, water does not need to be put into the inside of the drum 200 for drying only, and water in a liquid state condensed in the inside of the drum 200 does not need to be discharged to the outside of the drum 200. Accordingly, the drum 200 can omit a penetration hole provided along a circumferential surface. That is, the drum 200 for drying only can be formed differently from the drum 200 for washing.

[0112] The drum 200 can be configured in an integrated cylindrical shape, but can also be manufactured in a form in which a drum body 210 including a circumferential surface and a drum back 220 forming a rear surface are combined.

[0113] A drop inlet 211 through which laundry is put in and taken out can be provided in front of the drum body 210. A driving part that rotates the drum can be connected to the rear of the drum back 220. The drum body 210 and the drum back 220 can be combined using a fastening member such as a bolt, but are not limited thereto, and can be combined using various methods as long as they can rotate together.

[0114] A lifter 213 that pulls laundry in the inside upward to the upper portion can be provided in the drum body 210, so that the laundry accommodated in the inside is mixed with each other as it rotates. When the drum 200 rotates, the laundry accommodated in the inside can repeatedly go through a process of rising and falling through the lifter 213. The laundry accommodated in the inside of the drum 200 can be uniformly contacted with hot air as it rises and falls. Accordingly, it has an effect of improving drying efficiency and shortening drying time.

[0115] A reinforcing ring 212 can be formed in the circumferential surface of the drum body 210. The reinforcing ring 212 can be configured to be recessed or protruded from the inside / outside along the circumferential surface of the drum 200. The reinforcing ring as described above can be provided in plural and can be provided spaced apart from each other. The reinforcing ring can be provided in a prescribed pattern inside / outside the circumferential surface.

[0116] The rigidity of the drum body 210 can be improved by the reinforcing ring 212. Accordingly, even in a case where a large amount of laundry is accommodated in the drum body 210 or a rotational force is suddenly received through the driving part, the drum body 210 can be prevented from being misaligned. In addition, since the interval between the laundry and the inner circumferential surface can be increased in a case where the reinforcing ring 212 is provided, compared to a case where the circumferential surface of the drum body 210 is configured as a flat surface, the hot air supplied to the drum 200 can be more effectively flowed into between the laundry and the drum 200. Under the effect of the reinforcing ring, it has an effect of improving the durability of the drum and improving the drying efficiency of the laundry treating apparatus.

[0117] Generally, in the case of a DD type washing machine, the driving part is combined with and fixed to a tub that accommodates the drum 200, and the drum 200 can be supported to the tub in combination with the driving part. However, since the laundry treating apparatus of the present application is configured to collectively perform a drying course, a tub that is fixed to the cabinet 100 in order to accommodate the drum 200 will be omitted.

[0118] Accordingly, the laundry treating apparatus of the present application can further include a support part 400 that fixes or supports the drum 200 or the driving part inside the cabinet 100.

[0119] The support part 400 can include a front plate 410 disposed in front of the drum 200, and a rear plate 420 disposed in rear of the drum 200. The front plate 410 and the rear plate 420 can be configured in a plate shape and disposed to face each other in front and rear of the drum 200. The interval of the front plate 410 and the rear plate 420 can be the same as or greater than the length of the drum 200. The front plate 410 and the rear plate 420 can be fixed and supported to the bottom surface of the cabinet 100 or the base 800.

[0120] The front plate 410 can be disposed between a front surface panel forming a front surface of the cabinet and the drum 200. In addition, the front plate 410 can be provided with a loading communication hole 412 that communicates with the loading inlet 211. Since the loading communication hole 412 is provided in the front plate 410, not only the front of the drum 200 is supported, but also laundry can be loaded into or unloaded from the drum 200.

[0121] The front plate 410 can include a duct connection part 416 provided at the lower side of the loading communication hole 412. The duct connection part 416 can form the lower side surface of the front plate 410.

[0122] The front plate 410 can include a duct communication hole 417 that penetrates the duct connection part 416. The duct communication hole 417 can be in a hollow form and guide air discharged through the loading inlet 211 of the drum to the lower side of the drum 200. In addition, the air discharged through the loading inlet 211 can be guided to the circulation flow path part 820 located at the lower portion of the drum 200.

[0123] A filter part (not shown) can be provided in the duct communication hole 417 to be able to filter lint or large-particle impurities generated from laundry. The filter part can prevent impurities from being accumulated inside the laundry treating apparatus by filtering air discharged from the drum 200, and further can prevent the accumulation of impurities from hindering the circulation of air.

[0124] Since the inlet 211 is disposed in the front, the driving part is preferably disposed in the rear plate 420 compared to the case where the driving part is disposed in the front plate 410. The driving part can be mounted and supported in the rear plate 420. Thereby, the driving part can rotate the drum 200 in a state where the position thereof is stably fixed by the rear plate 420.

[0125] At least one of the front plate 410 and the rear plate 420 can support the drum 200 to enable rotation thereof. At least one of the front plate 410 and the rear plate 420 can accommodate the front end or the rear end of the drum 200 to enable rotation thereof.

[0126] For example, the front of the drum 200 can be rotatably supported in the front plate 410, and the rear of the drum 200 can be spaced apart from the rear plate 420 and indirectly supported in the rear plate 420 in connection with the motor part 500 mounted in the rear plate 420. Thereby, it is possible to minimize the area of the drum 200 that contacts or rubs against the support part 400, and to prevent unnecessary noise or vibration from being generated.

[0127] Of course, the drum 200 can also be configured to be rotatably supported in both the front plate 410 and the rear plate 420.

[0128] One or more support wheels 415 that support the front of the drum 200 can be disposed in the lower portion of the front plate 410. The support wheels 415 can be rotatably disposed in the back surface of the front plate 410. The support wheels 415 can rotate in a state of contacting the lower portion of the drum 200.

[0129] In the case where the drum 200 is rotated by the driving part, the drum 200 can be supported by the drum rotation shaft 6341 connected to the rear. If laundry is accommodated in the drum 200, the load that the drum rotation shaft 6341 bears can increase due to the laundry. Thus, there is a risk that the drum rotation shaft 6341 is bent by the load.

[0130] In the case where the support wheels 415 support the front lower portion of the drum 200, the load that the drum rotation shaft 6341 bears can be reduced. Thus, it is possible to prevent the drum rotation shaft 6341 from being bent, and to prevent noise from being generated due to vibration.

[0131] The support wheels 415 can support the load of the drum 200 in positions symmetrical to each other with reference to the center of rotation of the drum 200. Preferably, the support wheels 415 are disposed in the lower portions of the left and right sides of the drum 200 and support the drum 200. However, this is not limited thereto, and a greater number of support wheels 415 can be disposed according to the working environment of the drum 200.

[0132] The circulation flow path part 820 provided in the base 800 can form a flow path that circulates air inside the drum 200 and injects the air again into the inside of the drum 200.

[0133] The circulation flow path part 820 can include an inflow duct 821 that makes the air discharged from the drum 200 flow in, an outflow duct 823 that supplies air to the drum 200, and a movement duct 822 that connects the inflow duct 821 and the outflow duct 823.

[0134] In the case where the air is discharged from the front of the drum 200, the movement duct 822 can be located at the front side of the circulation flow path part 820. Also, the outflow duct 823 can be located at the rear side of the circulation flow path part 820.

[0135] The outflow duct 823 can further include an air supply part 8231 that discharges air to the outside of the circulation flow path part 820. The air supply part 8231 can be provided at the rear side of the outflow duct 823. The air discharged through the air supply part 8231 can move toward the drum 200.

[0136] A duct cover part 830 can be coupled to the upper side of the circulation flow path part 820, thereby shielding a part of the open top surface of the circulation flow path part 820. The duct cover part 830 can prevent air from flowing out to the outside of the circulation flow path part 820. In other words, the duct cover part 830 can form one side of the flow path through which air circulates.

[0137] In addition, the heat exchange part 900 provided in the base 800 can include a first heat exchanger 910 provided inside the circulation flow path part 820 to cool air, and a second heat exchanger 920 provided inside the circulation flow path part 820 to heat the air cooled in the first heat exchanger 910.

[0138] The first heat exchanger 910 can dehumidify the air discharged from the drum 200, and the second heat exchanger 920 can heat the dehumidified air. The heated air can be supplied again to the drum 200 to dry the laundry accommodated in the drum 200.

[0139] The first heat exchanger 910 and the second heat exchanger 920 can be configured as heat exchangers through which a refrigerant flows. In the case where the heat exchangers through which the refrigerant flows are configured, the first heat exchanger 910 can be configured as an evaporator, and the second heat exchanger 920 can be configured as a condenser. The refrigerant that can be configured to move along the first heat exchanger 910 and the second heat exchanger 920 can exchange heat with the air discharged from the drum 200.

[0140] The heat exchange portion 900 can include a circulation flow path fan 950 provided to the circulation flow path portion 820 and generating air flow inside the circulation flow path portion 820. In addition, the heat exchange portion 900 can further include a circulation flow path fan motor 951 rotating the circulation flow path fan 950. The circulation flow path fan 950 can be rotated by receiving rotational power from the circulation flow path fan motor 951. If the circulation flow path fan 950 is operated, air dehumidified in the first heat exchanger 910 and heated in the second heat exchanger 920 can move toward the rear of the drum 200.

[0141] The circulation flow path fan 950 can be provided to any one of the inflow duct 821, the moving duct 822, and the discharge duct 823. Since the circulation flow path fan 950 is configured to be rotatable, noise can be generated when the circulation flow path fan 950 is operated. Therefore, it is preferable that the circulation flow path fan 950 be disposed at the rear of the circulation flow path portion 820.

[0142] The circulation flow path fan 950 can be provided to the air supply portion 8231. In addition, the circulation flow path fan motor 951 can be located at the rear of the air supply portion 8231. If the circulation flow path fan 950 is rotated by the circulation flow path fan motor 951, air inside the circulation flow path portion 820 can be discharged to the outside of the circulation flow path portion 820 through the air supply portion 8231.

[0143] In order for a user to easily take out laundry located inside the drum 200, it is preferable that the introduction port 211 of the drum 200 be disposed at a relatively high position, and thus it is preferable that the circulation flow path portion 820 and the heat exchange portion 900 be disposed at the lower portion of the drum 200.

[0144] A rear plate 420 can be provided at the rear of the drum 200, guiding air discharged from the circulation flow path portion 820 toward the drum 200. The rear plate 420 can be disposed to be spaced apart from the drum back 220. The circulation flow path portion 820 can receive air inside the drum 200 through the front plate 410 and supply air to the drum 200 through the rear plate 420. Air discharged from the circulation flow path portion 820 can be guided to the drum 200 through the rear plate 420.

[0145] The base 800 can further include a connector 850 guiding air discharged from the circulation flow path portion 820 toward the rear plate 420. The connector 850 can guide the discharged air to be uniformly diffused to the entire area of the rear plate 420.

[0146] The connecting member 850 can be provided to the air supply part 8231. That is, the connecting member 850 can direct air discharged from the air supply part 8231 toward the rear plate 420. The hot air supplied to the rear plate 420 can flow into the inside of the drum 200 through the drum rear surface 220.

[0147] The drum 200 of the laundry treating apparatus of the present application can be rotated by being directly connected to the driving part located at the rear of the drum 200, rather than being indirectly rotated by being combined with a belt or the like. Accordingly, compared to the case where the drum of the conventional dryer is configured in a cylindrical shape with the front and rear being open, the rear of the drum of the laundry treating apparatus of the present application can be shielded and directly combined with the driving part.

[0148] As described before, the drum 200 can include a drum main body 210 configured in a cylindrical shape and accommodating laundry, and a drum rear surface 220 combined with the rear of the drum main body 210 and forming the rear surface of the drum.

[0149] The drum rear surface 220 is configured to shield the rear of the drum main body 210 and can provide a combined surface directly combined with the driving part. That is, the drum rear surface 220 can be configured to be connected to the driving part to receive rotational power, thereby rotating the entire drum 200. As a result, the front of the drum main body 210 is formed with a laundry loading port 211, and the rear is shielded by the drum rear surface 220.

[0150] The drum rear surface 220 can be provided with a shaft sleeve part 300 connecting the driving part and the drum rear surface 220. The shaft sleeve part 300 is provided to the drum rear surface 220 and can form the rotational center of the drum 200. Although the shaft sleeve part 300 can be formed in one body with the drum rear surface 220, in order to be firmly combined with a rotational shaft transmitting power, it can be configured of a material having rigidity or durability higher than that of the drum rear surface 220. The shaft sleeve part 300 can be seated and combined to the drum rear surface 220 to be coaxial with the rotational center of the drum rear surface 220.

[0151] The drum rear surface 220 can include a peripheral part 221 combined with the outer circumferential surface of the drum main body 210, and a mounting plate 222 provided to the inside of the peripheral part 221 and combined with the driving part. The shaft sleeve part 300 can be seated and combined to the mounting plate 222. A rotational shaft rotating the drum is combined to the mounting plate 222 through the shaft sleeve part 300, thereby having an effect of being able to be more firmly combined. In addition, the drum rear surface 220 can be prevented from being deformed.

[0152] The drum rear surface 220 can include a suction hole 224 formed through between the peripheral portion 221 and the mounting plate 222 and communicating the front and rear of the drum rear surface 220. The hot air supplied through the circulation flow path portion 820 can flow into the inside of the drum main body 210 through the suction hole 224. The suction hole 224 can be configured as a plurality of holes or a mesh-shaped mesh through the drum rear surface 220.

[0153] A driving portion that rotates the drum 200 can be located at the rear of the rear plate 420. The driving portion can include a motor portion 500 that generates a rotational force and a reducer 600 that reduces the rotational force of the motor portion 500 and transmits it to the drum 200.

[0154] The motor portion 500 can be disposed at the rear of the rear plate 420. The motor portion 500 can be combined with the rear of the rear plate 420 with the reducer 600.

[0155] The reducer 600 can be fixed to the rear surface of the rear plate 420, and the motor portion 500 can be combined with the rear surface of the reducer 600. That is, the rear plate 420 can provide a support surface that supports the reducer 600 or the motor portion 500. However, it is not limited thereto, and the motor portion 500 can also be combined with the rear plate 420.

[0156] Figure 5 is an exploded perspective view showing internal structures constituting the laundry treating apparatus separated from each other.

[0157] A laundry treating apparatus according to an embodiment of the present application can include a drum 200 that accommodates laundry, a front plate 410 that supports a front surface of the drum, a rear plate 420 that is located at the rear of the drum, a base 800 that is provided at a lower portion of the drum and provides a space for circulating air inside the drum or condensing moisture contained in the air, a motor portion 510, 520, 540 that is located at the rear of the drum and provides a rotational force to the drum, a reducer 600 that reduces the rotation of the motor portion and transmits it to the drum, and a rear cover 430 that is combined with the rear plate 420 and prevents the motor portion from being exposed to the outside.

[0158] The base 800 can include a circulation flow path portion 820 that communicates with the drum 200 and through which air flows from the drum to the circulation flow path portion 820 or is discharged from the circulation flow path portion 820 to the drum.

[0159] The front plate 410 can include a front panel 411 forming a front surface, and an insertion communication hole 412 formed to pass through the front panel 411 to communicate with the drum 200. The front plate 410 can be provided with a front sealing gasket 413 disposed at a rear surface of the front panel 411 and configured to surround a radial outer side of the insertion communication hole 412 to accommodate a portion of the drum body 210.

[0160] The front sealing gasket 413 can support the drum body 210 to be rotatable and be configured to be contactable with an outer circumferential surface or an inner circumferential surface of the insertion port 211. The front sealing gasket 413 can prevent hot air inside the drum 200 from leaking between the drum body 210 and the front plate 410. The front sealing gasket 413 can be composed of a plastic resin or an elastomer, and an additional sealing member can be additionally combined with the front sealing gasket 413 to prevent laundry or hot air from escaping from the drum body 210 to the front plate 410.

[0161] On the other hand, the front plate 410 can include a duct communication hole 417 configured to pass through an inner circumferential surface of the insertion communication hole 412. In addition, the front plate 410 can include a duct connection portion 416 extending to a lower side of the duct communication hole 417 and forming a flow path that communicates the drum body 210 and the circulation flow path portion 820.

[0162] The duct connection portion 416 can communicate with the drum body 210 through the duct communication hole 417, and air discharged from the drum body 210 flows into the duct connection portion 416 through the duct communication hole 417 and is then guided to the circulation flow path portion 820. Since the air discharged from the drum body 210 is guided to the circulation flow path portion 820 using the duct connection portion 416, it has an effect of being able to prevent air inside the drum from flowing out.

[0163] A filter member (not shown) can be provided in the duct connection portion 416, which filters impurities or lint from air discharged from the drum 200 to prevent impurities from flowing into the circulation flow path portion 820.

[0164] The front plate 410 can be provided with a support wheel 415 provided at a rear surface of the front panel 411 in a rotatable manner and supporting a lower portion of the drum 200. By supporting the front of the drum 200 by the support wheel 415, it has an effect of being able to prevent a rotation shaft connected to the drum from being bent.

[0165] The front plate 410 can be provided with a water storage tank support hole 414 configured to pass through the front panel 411 and capable of extracting or supporting a water storage tank 120 (refer to FIG. 1) for storing condensed water generated in a drying process.Figure 1 ) In the case where the water storage tank support hole 414 is provided at the upper side, the user does not need to bend over when drawing out the water storage tank, thus having an effect of improving the convenience of the user.

[0166] The drum 200 accommodating laundry can include a drum main body 210 provided with a laundry inlet / outlet 211 at the front of the drum, and a drum back 220 forming the rear aspect of the drum.

[0167] The drum back 220 can include a peripheral portion 221 connected to the drum main body 210, a suction hole 224 formed to penetrate the drum back 220 at the inside of the peripheral portion 221, and a mounting plate 222 provided at the center of rotation of the drum back 220 and combined with the rotating shaft. Air can flow in from the rear of the drum through the suction hole 224.

[0168] The drum back 220 can further include a reinforcing rib 225 extending from the peripheral portion 221 toward the center of rotation. The reinforcing rib 225 can extend while avoiding the suction hole 224. The reinforcing rib 225 can have an effect of preventing the rigidity of the drum back 220 from being reduced due to the suction hole 224. The reinforcing rib 225 can be configured to extend radially from the outer circumferential surface of the mounting plate 222 toward the inner circumferential surface of the peripheral portion 221.

[0169] In addition, the drum back 220 can further include a circumferential rib 227 extending along the circumference of the drum back 220 and connecting the reinforcing ribs 225 to each other. The suction hole 224 can be disposed between each of the reinforcing ribs 225, the circumferential rib 227, and the peripheral portion 221. The reinforcing ribs 225 and the circumferential rib 227 can have an effect of preventing the deformation of the drum back 220 even when the drum back 220 receives a rotational force from the motor portion 500.

[0170] The inflow duct 821 can be configured to communicate with the duct communication hole 417 of the front plate 410, and then communicate with the flow path provided inside the front plate 410. The moving duct 822 can extend from the end of the inflow duct 821 toward the rear of the drum 200, and the discharge duct 823 can be provided at the end of the moving duct 822 and configured to direct the air toward the drum 200.

[0171] The air supply portion 8231 can be located at the downstream side of the discharge duct 823, and the air supply portion 8231 can provide a space in which a circulating flow path fan is installed. If the circulating flow path fan operates, the air flowing in the inflow duct 821 can be discharged to the upper portion of the air supply portion 8231.

[0172] On the other hand, the base 800 can be provided with a heat exchanger 900 that can cool and heat air circulating inside the drum 200. The heat exchanger 900 can include a compressor 930 connected to the first and second heat exchangers and supplying compressed refrigerant. Since the compressor 930 can be configured not to directly exchange heat with the circulating air, it can be located outside the circulating flow path portion 820.

[0173] In addition, the heat exchanger can include a circulating flow path fan motor 951 supported at the rear of the air supply portion 8231 and rotating the circulating flow path fan. The circulating flow path fan motor 951 can be coupled to the rear of the air supply portion 8231.

[0174] On the other hand, the laundry treating apparatus according to an embodiment of the present application can further include a connecting member 850 coupled to the circulating flow path portion 820 and guiding the hot air discharged from the circulating flow path portion 820 toward the rear of the drum 200 or the rear plate 420.

[0175] The connecting member 850 can be disposed at the upper portion of the discharge duct 823 and configured to guide the hot air heated in passing through the second heat exchanger 920 to a position higher than the discharge duct 823. In addition, the connecting member 850 can be coupled to an opening portion provided at the upper side of the air supply portion 8231.

[0176] The connecting member 850 can be configured to have a flow path formed therein. The connecting member 850 can be configured to uniformly guide the flow of air generated by the circulating flow path fan toward the rear plate 420. That is, the connecting member 850 can be configured such that the area of the flow path thereof increases farther from the air supply portion 8231.

[0177] The rear plate 420 can be coupled to or supported by the base 800 and located at the rear of the drum 200. The rear plate 420 can include a rear panel 421 configured to face the front panel 410 and a duct portion 423 recessed from the rear panel 421 and forming a flow path for air flow, configured to guide air discharged from the circulating flow path portion 820 toward the drum.

[0178] The rear plate 420 can include a mounting portion 425 to which the driving portion is coupled or supported. The mounting portion 425 can be configured to penetrate the rear panel 421 and disposed at the inner circumferential surface of the duct portion 423. The mounting portion 425 can be configured to be spaced apart from the inner circumferential surface of the duct portion 423 toward the radial inner side.

[0179] Here, as described above, the driving part can mean a combination of the decelerator 600 and the motor part 500. Also, the driving part can mean only the motor part 500. That is, a structure that generates power and transmits rotational power to the drum can be referred to as a driving part.

[0180] The driving part can be installed to the mounting part 425. The mounting part 425 can support a load of the driving part. The driving part can be connected with the drum 200 in a state of being supported by the mounting part 425.

[0181] The duct part 423 can be configured to accommodate a portion of the drum back face 220. The duct part 423 can form a flow path for air movement together with the drum back face 220.

[0182] The driving part can be provided to the mounting part 425 and configured not to interfere with the duct part 423. That is, the driving part can be configured to be spaced apart from the inner circumferential surface of the duct part 423 to the radial inner side. The driving part is provided to the mounting part 425 and configured to be exposed to the outside in the rear direction, thereby enabling the driving part to be cooled by external air.

[0183] The driving part can further include a motor part 500 that provides power to rotate the drum 200. The motor part 500 can include a stator 510 that generates a rotating magnetic field and a rotor 520 configured to rotate by the stator 510.

[0184] The rotor 520 can be configured as an outer rotor type that accommodates the stator 510 and is configured to rotate along the circumference of the stator 510. At this time, the driving shaft can also be combined with the rotor 520 and directly connected with the drum 200 by penetrating the stator 510 and the mounting part 425. In this case, the rotor 520 can directly transmit power to rotate the drum 200.

[0185] The rotor 520 can be combined with the driving shaft through a washer part 540. The washer part 540 can perform a function of connecting the driving shaft and the rotor 520. Since the contact area between the rotor 520 and the driving shaft can be increased by the washer part 540, it has an effect of being able to more effectively transmit rotation of the rotor 520.

[0186] The decelerator 600 can be configured to connect the motor portion 500 and the drum 200. The decelerator 600 can convert power of the motor portion 500 and rotate the drum 200. The decelerator 600 can be configured between the motor portion 500 and the drum 200, receive power of the motor portion 500, and transmit it to the drum 200 after conversion. The decelerator 600 can be configured to convert RPM of the rotor to a smaller RPM and transmit it to the drum 200 after increasing a torque value.

[0187] In particular, the decelerator 600 can be combined with a driving shaft that rotates together with the rotor 520 combined with the rotor 520. The decelerator 600 can internally include a gear combination that meshes with the driving shaft to rotate, thereby being able to change rpm of the driving shaft and increase torque, and can be connected with a drum rotating shaft that rotates the drum 200 combined with the drum 200. Accordingly, when the driving shaft 530 rotates, although the drum rotating shaft rotates at a lower rpm than the driving shaft, it can rotate at a greater torque.

[0188] Performance of such a decelerator 600 will depend on whether the driving shaft and the drum rotating shaft can be maintained coaxial. That is, if the driving shaft and the drum rotating shaft are misaligned with each other, there is a risk that components constituting the gear combination inside the decelerator 600 are misaligned or the combination is released with at least one of the driving shaft, the drum rotating shaft. Accordingly, power of the driving shaft can not be normally transmitted to the drum rotating shaft, or a phenomenon in which the driving shaft idles occurs.

[0189] In addition, even if the driving shaft and the drum rotating shaft are temporarily misaligned, gears inside the decelerator 600 will be misaligned with each other and collide, resulting in generation of unnecessary vibration or noise.

[0190] In addition, in the case where the driving shaft and the drum rotating shaft are misaligned by an angle, even temporarily, there can be a risk that the decelerator 600 completely escapes from a prescribed position or is damaged.

[0191] In order to prevent such a situation, in a laundry treating apparatus having a decelerator, it is preferable that the decelerator 600 and the motor portion 500 are generally fixed to a support body that does not deform even if external force occurs and maintains an original state.

[0192] For example, in the case of a washing machine, it is possible to adopt a manner in which, after an outer tub, which accommodates the drum, is once fixed to a cabinet, the motor portion and the decelerator are twice fixed to a bearing housing made of a rigid body, which is internally embedded in the outer tub in a manner of injection molding. Thereby, even if the outer tub generates a considerable vibration, the decelerator and the driving portion can be inclined or vibrated together with the bearing housing or the fixed steel plate. As a result, an effect that the decelerator and the driving portion themselves always remain in a state of being combined can be derived, and a state in which the driving shaft and the rotation shaft are coaxial can be maintained.

[0193] However, since the laundry treating apparatus of the present application is configured as a dryer, a structure of an outer tub fixed inside a cabinet will be omitted. In addition, a back panel of the cabinet is configured of a relatively thin plate, and thus, even if the stator 510 is fixed to the back panel of the cabinet, the back panel can be easily vibrated or bent by a reaction force when the rotor 520 rotates. If the back panel is vibrated or even temporarily bent, a problem that the rotation centers of the decelerator 600 and the motor portion 500, which are configured to be combined with the drum 200, are misaligned with each other can occur.

[0194] In addition, since the back panel is configured of a thin steel plate, it is not easy to simultaneously support the decelerator 600 and the motor portion 500. For example, in the case in which the decelerator 600 and the motor portion 500 are combined in parallel with the back panel, a torque can be generated due to the total length of the decelerator 600 and the motor portion 500 and the weight thereof and can cause a problem that the decelerator 600 is sagged. As a result, the drum rotation shaft combined with the drum can be misaligned with the decelerator 600, and thus, it can be impossible to maintain the driving shaft coaxial.

[0195] On the other hand, it can be considered to support the motor portion 500 by the stator 510 combined with the rear plate 420. In the case in which a large amount of laundry is accommodated inside the drum 200 or eccentricity is generated, the drum rotation shaft can be misaligned with the arrangement of the laundry at every rotation of the drum 200. At this time, since the stator 510 is additionally separated from the drum 200 and fixed to the rear plate 420, the drum rotation shaft can be vibrated at a different magnitude from the stator 510 or inclined at a different angle. Thus, the drum rotation shaft and the driving shaft can be impossible to maintain coaxial.

[0196] In another aspect, the drum 200 can be supported by the front plate 410 and the rear plate 420, thereby being able to fix the position of installation to some extent. Accordingly, the position of the drum rotating shaft combined with the drum 200 can also be fixed to some extent. Thus, even if the drum 200 vibrates, the vibration can be damped by at least one of the front plate 410 or the rear plate 420.

[0197] However, when the vibration generated in the drum 200 is transmitted to the motor portion 500, even if the decelerator 600 and the motor portion 500 are fixed to the rear plate 420, the vibration amplitude of the motor portion 500 and the rear plate 420 can be greater than the vibration amplitude of the drum rotating shaft vibration. At this time, it can also be possible that the driving shaft and the drum rotating shaft cannot be maintained coaxial.

[0198] To solve such a problem, the laundry treating apparatus of the present application can combine and fix the motor portion 500 to the decelerator 600. In other words, the decelerator 600 itself can perform the role of the reference point of the entire driving portion. That is, the decelerator 600 can perform the reference role of the amount of angle of vibration and inclination of the entire driving portion.

[0199] Since the motor portion 500 is fixed only to the decelerator 600 and not to other structures of the laundry treating apparatus, in the case where vibration or external force is transmitted to the driving portion, when the decelerator 600 is inclined or vibrates, the motor portion 500 can always be inclined or vibrate simultaneously with the decelerator 600.

[0200] As a result, the decelerator 600 and the motor portion 500 can form one vibration system, and the decelerator 600 and the motor portion 500 can be maintained in a fixed state with each other as a reference without performing relative movement.

[0201] The stator 510 in the motor portion 500 can be directly combined and fixed to the decelerator 600. Thus, the position in which the driving shaft 530 is disposed with the decelerator 600 as a reference can not change. The driving shaft 530 and the decelerator 600 can be configured in a state in which the centers thereof coincide with each other, and the driving shaft 530 can rotate in a state in which the center thereof is maintained coaxial with the center of the decelerator 600.

[0202] The first axis M1 can represent an imaginary line extending in the forward and rearward directions along the center of rotation of the drum 200. That is, the first axis M1 can be parallel to the X axis.

[0203] The second axis M2 and the third axis M3 can represent imaginary lines extending upward from the front to the rear of the laundry treating apparatus. That is, the second axis M2 and the third axis M3 can be disposed parallel to the XZ plane or orthogonally to the Y axis.

[0204] The first axis M1 and the second axis M2 can cross each other at the decelerator 600. In addition, the first axis M1 and the third axis M3 can cross each other at the mounting portion 425.

[0205] The decelerator 600 and the motor portion 500 can be designed to be disposed along the first axis M1 parallel to the ground in the case where the drum 200 has no load or the motor portion 500 is not operated.

[0206] However, in the case where the drum 200 or the motor portion 500 is vibrated, since the vibration is transmitted to the decelerator 600 and the decelerator 600 is inclined, the decelerator 600 can temporarily reach a state of being inclined along the second axis M2.

[0207] At this time, since the motor portion 500 is in a state of being combined with the decelerator 600, it will be possible to vibrate or be inclined together with the decelerator 600. Thus, the motor portion 500 can be disposed parallel to the decelerator 600 on the second axis M2. Accordingly, the drive shaft and the drum rotation axis can also be disposed parallel along the second axis M2.

[0208] As a result, even if the decelerator 600 is inclined, the motor portion 500 can move integrally with the decelerator 600, and the drive shaft and the drum rotation axis can be maintained coaxial.

[0209] The decelerator 600 can be combined and fixed to the rear plate 420. In this case, since the decelerator 600 will be inclined or vibrated in a state of being combined with the rear plate 420, it can be regarded that the rear plate 420 performs a role as a center of a vibration system including the decelerator 600, the motor portion 500, and the drum 200. In this case, the motor portion 500 can also be combined and fixed only to the decelerator 600 without being directly combined with the rear plate 420.

[0210] In the case where the decelerator 600 and the motor portion 500 and the drum 200 are originally disposed parallel along the first axis M1, the decelerator 600 can be inclined parallel to the third axis M3 due to vibration of the drum 200 or the motor portion 500. The third axis M3 can pass through the decelerator 600 combined to the rear plate 420. At this time, since the decelerator 600 and the motor portion 500 are combined, the motor portion 500 can also be inclined parallel to the third axis M3 in the same manner as the decelerator 600. In the case where the decelerator 600 and the motor portion 500 and the drum 200 are originally disposed parallel along the first axis M1, the decelerator 600 can be inclined parallel to the third axis M3 due to vibration of the drum 200 or the motor portion 500. The third axis M3 can pass through the decelerator 600 combined to the rear plate 420. At this time, since the decelerator 600 and the motor portion 500 are combined, the motor portion 500 can also be inclined parallel to the third axis M3 in the same manner as the decelerator 600.

[0211] As a result, the motor part 500 and the drum 200, which are combined to the decelerator 600, can be inclined or simultaneously vibrated in parallel to each other with the decelerator 600 as a reference.

[0212] The aforementioned coaxial and consistent meanings do not mean physically perfect coaxial and consistent, but a concept in which a range of errors acceptable in mechanical engineering or a range of levels in which a person skilled in the art considers coaxial or consistent is allowed. For example, a state in which the driving shaft 530 and the drum rotation shaft 6341 are misaligned by a range of 5 degrees can be defined as a coaxial or consistent state. However, such an angle value is only an example, and an error allowed in design can be changed.

[0213] Although the driving shaft 530 rotates with the decelerator 600 as a reference, it is fixed to prevent inclination, and the stator 510 is also fixed to the decelerator 600, so the interval between the stator 510 and the rotor 520 can always be kept constant. As a result, collision of the stator 510 and the rotor 520 can be prevented, and noise or vibration caused by a change in the center of rotation of the rotor 520 as it rotates with respect to the stator 510 can be blocked at the source.

[0214] The drum rotation shaft 6341 is disposed to extend toward the drum 200 inside the decelerator 600, and can vibrate together with the decelerator 600 and be inclined together with the decelerator 600. That is, the drum rotation shaft 6341 is configured to rotate only the decelerator 600, and the position where it is installed can be fixed. As a result, the drum rotation shaft 6341 and the driving shaft 530 can always be configured in parallel, and can form a coaxial state. In other words, the center of the drum rotation shaft 6341 and the center of the driving shaft 530 can be kept in a state of being consistent with each other.

[0215] On the other hand, a sealing part 450 can be configured between the drum back surface 220 and the rear plate 420. The sealing part 450 can seal between the drum back surface 220 and the rear plate 420 so that air flowing into the duct part 423 of the rear plate 420 does not flow out to the outside, but flows into the suction hole 224.

[0216] The sealing part 450 can be configured on the outer side surface and the inner side surface of the duct part 423, respectively. A first sealing member 451 can be provided on the radially outer side of the duct part 423, and a second sealing member 452 can be provided on the radially inner side. The first sealing member 451 can prevent hot air from flowing out to the radially outer side between the drum back surface 220 and the duct part 423, and the second sealing member 452 can prevent hot air from flowing out to the radially inner side between the drum back surface 220 and the duct part 423.

[0217] In other words, the sealing part 450 can be disposed at the radially outer side and the radially inner side of the suction hole 224, respectively. The first sealing member 451 can be disposed at the radially outer side of the suction hole 224, and the second sealing member 452 can be disposed at the radially inner side of the suction hole 224.

[0218] In order to prevent the hot air from flowing out, the sealing part 450 is preferably configured to be in contact with both the drum back 220 and the rear plate 420. Since the drum 200 rotates during the operation of the laundry treating apparatus, the drum back 220 will continuously apply friction to the sealing part 450. Therefore, the sealing part 450 is preferably made of a material whose performance does not decrease due to the frictional force and frictional heat generated with rotation and is capable of sealing between the drum back 220 and the duct part 423.

[0219] On the other hand, the motor part 500 or the decelerator 600 can be coupled at the rear of the rear plate 420, and since the rear plate 420 can be formed of a thin iron plate material, there is a possibility that bending or deformation can occur due to the load transmitted to the decelerator 600 through the decelerator 600 and the drum 200. That is, in order to mount the decelerator 600, the motor part 500, etc., it is necessary to secure the rigidity of the rear plate 420.

[0220] To this end, the rear plate 420 can further include a bracket 700 for reinforcing the coupling rigidity. The decelerator 600 and the motor part 500 can be coupled to the rear plate 420 using the bracket 700, in which the bracket 700 can be additionally coupled to the rear plate 420.

[0221] The decelerator 600 can be coupled to both the bracket 700 and the rear plate 420. It can be coupled by being penetrated by a fastening member at the same time. The rigidity of the rear plate 420 can be secured by the coupling of the bracket 700. The rear plate 420, in which the rigidity is secured, can be coupled to the decelerator 600, the motor part 500, etc.

[0222] Fastening can be performed in a manner in which the decelerator 600 is first coupled to the bracket 700, and then the bracket 700 is coupled to the rear plate 420. That is, the decelerator can also be fixed to the rear plate 420 using the bracket 700, without being directly coupled to the rear plate 420.

[0223] On the other hand, in the case in which the motor part 500 or the decelerator 600 is coupled at the rear of the rear plate 420, the motor part 500 and the decelerator 600 can be exposed to the outside. Therefore, it is necessary to couple the rear cover 430 at the rear of the rear plate 420 to prevent the motor part 500 from being exposed. In addition, the duct part 423 can be heated by the hot air. Therefore, it is necessary to insulate the back of the duct part 423.

[0224] The rear cover 430 can be combined at the rear of the rear plate 420 to prevent the duct portion 423, the motor portion 500, or the reducer 600 from being exposed to the outside. The rear cover 430 can be disposed apart from the duct portion 423 and the driving portion.

[0225] The rear cover 430 has an effect of preventing the motor portion 500 from being damaged by external interference or a situation in which drying efficiency is decreased due to heat loss through the duct portion 423.

[0226] Figure 6 An appearance of a reducer according to an embodiment of the present application is illustrated.

[0227] The reducer 600 can include a reducer housing 610, 620 forming an appearance of the reducer 600. The reducer housing can include a first housing 610 configured to face the drum and a second housing 620 configured to face the motor portion.

[0228] The reducer 600 can include a gear box. The gear box can be configured to receive power from the motor portion, convert RPM of the motor portion to a smaller RPM, and increase a torque value and deliver to the drum. Most of the gear box is accommodated inside the second housing 620, and the first housing 610 can shield the inside of the reducer 600. Thereby, the overall thickness of the reducer 600 can be reduced. Detailed structures of the gear box will be described later.

[0229] The first housing 610 can include a first housing blocking body 611 configured to shield the second housing 620, and a first housing shaft receiving portion 612 extending from the first housing blocking body 611 in a direction away from the second housing 620. The first housing shaft receiving portion 612 can accommodate the drum rotating shaft 6341 and support the drum rotating shaft 6341 to be rotatable.

[0230] The first housing 610 can include a stator coupling portion 613 supporting the motor portion. The stator coupling portion 613 can extend from a circumferential surface of the first housing blocking body 611 in a direction away from the first housing shaft receiving portion 612.

[0231] The stator coupling portion 613 can include a stator fastening hole 615 capable of fastening the motor portion. The stator fastening hole 615 can be recessed in the stator coupling portion 613. An additional fastening member can be inserted into the stator fastening hole 615. The stator coupling portion 613 and the motor portion can be coupled by the fastening member.

[0232] The first housing 610 can further include a coupling guide 614 guiding coupling of a motor part. The coupling guide 614 can extend from the circumference of the first housing block body 611 in a direction away from the first housing shaft receiving part 612. The coupling guide 614 can extend from the first housing block body 611 and be connected with the stator coupling part 613. In the case where the stator 510 is coupled to the stator coupling part 613, the coupling guide 614 can guide the position of the stator 510. Thereby, the assemblability can be improved.

[0233] Referring to Figure 6 A gear coupling body can be accommodated inside the second housing 620. In general, a gear box coupled with the reducer 600 can include a sun gear, a planetary gear which revolves with respect to the sun gear, and a ring gear which accommodates the planetary gear and guides rotation of the planetary gear. The second housing 620 can include a second housing coupling body 621 coupled with the first housing 610, a second housing block body 622 extending from the second housing coupling body 621 in a direction away from the first housing 610 to form a space in which the gear box is accommodated, and a second housing shaft receiving part 623 extending from the inner circumference of the second housing block body 622 in a direction away from the first housing 610 to support the drive shaft 530.

[0234] The center of the first housing 610 and the center of the second housing 620 can be designed to be disposed on the same axis. The drive shaft 530 and the drum rotating shaft 6341 are located on the same axis, which is advantageous for transmission. Accordingly, the first housing shaft receiving part 612 which rotatably supports the drum rotating shaft 6341 and the second housing shaft receiving part which rotatably supports the drive shaft 530 are preferably coupled in a manner constituting the same axis.

[0235] The drive shaft 530 can be inserted into the inside of the second housing 620 and be rotatably supported inside the second housing 620. The drive shaft 530 can be coupled with a washer part 540 which rotatably supports the rotor 520. The washer part 540 can include an accommodation body 542 in which an axis support hole 543 for accommodating the drive shaft 530 is formed at the center, and a washer coupling body 541 extending radially from the outer circumference of the accommodation body to form a surface coupled with the rotor. The axis support hole 543 can be configured in a groove shape corresponding to a protrusion so that the protrusion formed on the outer circumference of the drive shaft 530 can be coupled therewith.

[0236] The gasket portion 540 can include one or more gasket coupling protrusions 5411 configured to protrude from the gasket coupling body 541 in a direction away from the decelerator. In addition, the gasket portion 540 can include one or more gasket coupling holes 5412 passing through the gasket coupling body 541.

[0237] The gasket coupling protrusions 5411 can be coupled with the receiving grooves formed on the rotor. The gasket coupling holes 5412 can be used to insert a fastening member passing through the rotor to couple the rotor with the gasket portion 540.

[0238] The gasket coupling protrusions 5411 and the gasket coupling holes 5412 can be alternately disposed circumferentially on the surface of the gasket coupling body 541, and a plurality of them can be provided.

[0239] Figure 7 is a sectional view of the driving portion shown in brief in Figure 2 is a sectional view of the driving portion shown in brief in

[0240] The driving portion can include a motor portion 500 generating a rotational force, and a decelerator for reducing the rotational speed of the motor portion 500 and transmitting it to the drum. The decelerator 600 can include a drum rotating shaft 6341 rotating the drum.

[0241] The motor portion 500 can include a stator 510 generating a rotating magnetic field by receiving an external power source, and a rotor 520 configured to surround the outer circumferential surface of the stator 510. A permanent magnet can be disposed on the inner circumferential surface of the rotor 520.

[0242] The permanent magnet on the inner circumferential surface of the rotor 520 can move in a certain direction under the action of the rotating magnetic field generated by the stator 510, and the permanent magnet can be fixed to the inner circumferential surface of the rotor 520. Accordingly, the rotor 520 can rotate using the rotating magnetic field of the stator 510.

[0243] A driving shaft 530 can be coupled to the center of rotation of the rotor 520, and the driving shaft 530 rotates together with the rotor 520 and transmits the rotational force of the rotor 520. The driving shaft 530 can be configured to rotate together with the rotor 520. The driving shaft 530 can be coupled to the rotor 520 through a gasket portion 540.

[0244] The driving shaft 530 can be directly connected to the rotor 520, but since it can be more firmly coupled to the rotor 520 when connected through the gasket portion 540, it can more effectively transmit the rotational force of the rotor 520. In addition, since the load is prevented from being concentratedly applied to the driving shaft 530, it has the effect of being able to increase the durability of the driving shaft 530.

[0245] The driving shaft 530 can be directly connected with the drum, but since the driving shaft 530 rotates at the same speed as the rotational speed of the rotor 520, a situation in which speed reduction is required can occur. Accordingly, the driving shaft 530 can be connected with a speed reducer, and the speed reducer can be connected with the drum. That is, the speed reducer can rotate the drum by reducing the rotation of the driving shaft 530.

[0246] The speed reducer 600 can include a first case 610 and a second case 620 forming an appearance thereof, and a gear box 630 of power of the driving shaft 530. The second case 620 can provide a space capable of accommodating the gear box 630, and the first case 610 can shield the accommodation space provided by the second case 620.

[0247] The second case 620 can include a second case coupling body 621 coupled with the first case 610, a second case blocking body 622 extending rearward from an inner circumferential surface of the second case coupling body 621 to form an accommodation space and accommodate the gear box 630, and a second case shaft receiving portion 623 extending rearward from the second case blocking body 622 and configured to accommodate the driving shaft 530.

[0248] The gear box 630 can include a ring gear 633 provided along an inner circumferential surface of the second case blocking body 622. One or more planetary gears 632 can be provided on the inner circumferential surface of the ring gear 633 in a gear-coupled manner with the ring gear 633, and a sun gear 631 can be provided on the inner side of the ring gear 633, the sun gear 631 being coupled in a gear-coupled manner with the planetary gears 632 and rotating together with the driving shaft 530.

[0249] The sun gear 631 can be configured to be coupled with and rotate together with the driving shaft 530. The sun gear 631 can be formed of a member separate from the driving shaft 530, but is not limited thereto, and the sun gear 631 can be formed integrally with the driving shaft 530.

[0250] The sun gear 631, the planetary gears 632, and the ring gear 633 can be formed as helical gears. In the case where each of the gears is formed as a helical gear, noise can be reduced and transmission efficiency can be increased. However, the sun gear 631, the planetary gears 632, and the ring gear 633 can be formed as spur gears, but are not limited thereto.

[0251] As an operation example of the gear box 630, as the rotor rotates, when the driving shaft 530 and the sun gear 631 connected with the driving shaft 530 rotate, the planetary gears 632 coupled in a gear-coupled manner on the outer circumferential surface of the sun gear 631 can be coupled in a gear-coupled manner between the ring gear 633 and the sun gear 631 and rotate.

[0252] The planetary gear 632 can include a planetary gear shaft 6323 inserted into the center of the rotation. The planetary gear shaft 6323 can rotatably support the planetary gear 632.

[0253] The decelerator can further include a first gear housing 6342 and a second gear housing 6343 supporting the planetary gear shaft 6323. The planetary gear shaft 6323 can be supported by the second gear housing 6343 in the front and by the first gear housing 6342 in the rear.

[0254] The drum rotation shaft 6341 can be disposed extending from the rotation center of the second gear housing 6343 in a direction away from the motor part. The drum rotation shaft 6341 can be formed of a structure separate from the second gear housing 6343, and combined therewith and rotate together. On the other hand, the drum rotation shaft 6341 can also extend from the second gear housing 6343 and be formed in one body with the second gear housing 6343.

[0255] The drum rotation shaft 6341 can rotate the drum in combination with the drum. As described above, the drum rotation shaft 6341 can be combined with the drum using a connecting body such as a bushing part, and can be directly combined with the drum without an additional connecting body.

[0256] The drum rotation shaft 6341 can be supported by the first housing 610. The first housing 610 can include a first housing blocking body 611 that blocks the accommodation space of the second housing 620, and a first housing shaft receiving part 612 that extends from the first housing blocking body 611 in a direction away from the second housing 620 to accommodate the drum rotation shaft 6341. A first bearing 660 and a second bearing 670 can be provided in a press-fitted manner on the inner circumferential surface of the first housing shaft receiving part 612, thereby being able to rotatably support the drum rotation shaft 6341.

[0257] The first housing 610 and the second housing 620 can be combined with each other by a decelerator fastening member 681. In addition, the decelerator fastening member 681 can pass through the first housing 610 and the second housing 620 at the same time to combine the two members. In addition, the decelerator fastening member 681 can pass through the first housing 610, the second housing 620, and the rear panel 420 at the same time to fix the decelerator 600 to the rear panel 420 while combining the first housing 610 and the second housing 620.

[0258] The rear plate 420 can be formed of an iron plate having a thin thickness. Accordingly, it can be difficult to secure rigidity required to support the decelerator 600, the motor portion 500 combined with the decelerator 600, and the drum 200 connected with the decelerator 600. Accordingly, when the decelerator 600 is combined with the rear plate 420, a bracket 700 can be used to secure rigidity of the rear plate 420. The bracket 700 can be formed of a material having higher rigidity than the rear plate 420, and can be combined with a front surface or a rear surface of the rear plate 420.

[0259] The bracket 700 can be combined with the front surface of the rear plate 420 to secure rigidity in which the decelerator 600 can be combined, and the decelerator 600 can be combined with the rear plate 420 and the bracket 700 at the same time. In order to combine the rear plate 420, the bracket 700, and the decelerator, a fastening member such as a screw can be used.

[0260] In addition, in order to fix the decelerator 600 to the rear plate 420, the decelerator fastening member 681 used when the first housing 610 and the second housing 620 are combined can be used. That is, the decelerator fastening member 681 can be combined by penetrating the second housing 620, the first housing, the rear plate 420, and the bracket 700 at one time. In the case of being combined in the manner as described above, the front of the rear plate 420 can be supported by the bracket 700, and the rear can be supported by the first housing 610, and thus, rigidity can be secured even based on the combination of the decelerator 600. However, it is not limited thereto, and the decelerator 600 can be combined to the rear plate 420 using an additional fastening member after the first housing 610 and the second housing 620 are combined using the decelerator fastening member 681 at first.

[0261] In addition, a stator combining portion 613 can be formed at a radially outer side of the first housing 610, and the motor portion 500 can be combined with the stator combining portion 613. The stator combining portion 613 can include a combining groove recessed in the stator combining portion 613.

[0262] The stator 510 can be directly combined with the rear plate 420, but can be combined with the stator combining portion 613. The stator 510 can include a fixing rib 512 provided at an inner circumferential surface thereof to support the stator. The fixing rib 512 can be combined with the stator combining portion 613. The fixing rib 512 and the stator combining portion 613 can be combined with each other using a stator combining pin 617.

[0263] The motor portion 500 and the decelerator 600 can form one vibration body by being combined with the decelerator 600 in a state of being spaced apart from the rear plate 420. Accordingly, even if vibration is applied from the outside, the driving shaft 530 combined with the rotor 520 and the drum rotating shaft 6341 connected to the decelerator 600 can be easily maintained coaxial.

[0264] The drum rotating shaft 6341 has a risk that the direction of the shaft thereof can be misaligned due to vibration of the drum 200. However, since the motor portion 500 is combined with the first housing 610 supporting the drum rotating shaft 6341, even if the shaft direction of the drum rotating shaft 6341 is misaligned, the shaft direction of the driving shaft 530 will be similarly misaligned due to the first housing 610. That is, the motor portion 500 can be integrally moved with the decelerator 600, so that the drum rotating shaft 6341 and the driving shaft 530 can be maintained coaxial even if force is applied from the outside.

[0265] Through the combined structure as described above, efficiency and reliability of transmission of power generated by the motor portion 500 to the drum 200 are improved, and cases such as abrasion of the gear case 630, reduction in efficiency of transmission, and reduction in durability and reliability due to misalignment of the shafts of the drum rotating shaft 6341 and the driving shaft 530 can be prevented.

[0267] Referring to Figure 8 The rear plate 420 can be located at the rear of the drum. The rear plate 420 can guide the hot air discharged from the circulating flow path portion 820 to the drum. That is, the rear plate 420 can be located at the rear of the drum to form a flow path so that the hot air is uniformly supplied to the entire drum.

[0268] The rear plate 420 can include a rear panel 421 facing the rear surface of the drum, and a duct portion 423 recessed from the rear panel 421 to the rear to form a flow path. The duct portion 423 can be provided by being pressed from the rear panel 421 to the rear. The duct portion 423 can be configured to accommodate a portion of the rear surface of the drum.

[0269] The duct portion 423 can include an inflow portion 4233 located at the rear of the circulating flow path portion, and a flow portion 4231 located at the rear of the drum. The flow portion 4231 can be configured to accommodate a portion of the drum. The flow portion 4231 can accommodate a portion of the drum, thereby forming a flow path provided at the rear of the drum.

[0270] The flow portion 4231 can be configured in a ring shape to face the suction hole formed on the back surface of the drum. The flow portion 4231 can be recessed from the rear panel 421. That is, the flow portion 4231 can be configured to be open in front thereof, and form a flow path together with the back surface of the drum.

[0271] In the case where the front of the flow portion 4231 is configured to be open, the hot air moving to the flow portion 4231 can directly move to the drum without passing through an additional structure. Accordingly, it is possible to prevent a situation in which heat loss occurs in the process in which the hot air passes through the additional structure. That is, it has an effect of being able to increase the drying efficiency by reducing heat loss of the hot air.

[0272] The rear panel 420 can include an installation portion 425 provided on the radially inner side of the flow portion 4231. The installation portion 425 can provide a space for coupling the decelerator 600 or the motor portion 500. That is, the rear panel 420 can include the installation portion 425 provided on the inner side thereof and the flow portion 4231 configured in a ring shape on the radially outer side of the installation portion 425.

[0273] Specifically, the flow portion 4231 can include a flow outer circumferential portion 4231a surrounding the inner space in which the hot air flows from the outside. In addition, the flow portion 4231 can include a flow inner circumferential portion 4231b surrounding the inner space in which the hot air flows from the inside. That is, the flow outer circumferential portion 4231a can form the outer circumferential edge of the flow portion 4231, and the flow inner circumferential portion 4231b can form the inner circumferential edge of the flow portion 4231.

[0274] In addition, the flow portion 4231 can include a flow recessed surface 4232 forming the rear surface of the flow path through which the hot air moves. The flow recessed surface 4232 can be configured to connect the flow outer circumferential portion 4231a and the flow inner circumferential portion 4231b. That is, the space through which the hot air discharged from the circulating flow path portion 820 flows can be formed by the flow inner circumferential portion 4231b, the flow outer circumferential portion 4231a, and the flow recessed surface 4232.

[0275] In addition, the hot air can be guided toward the drum by the flow recessed surface 4232, preventing the hot air from leaking to the rear. That is, the flow recessed surface 4232 can mean the recessed surface of the flow portion 4231.

[0276] The inflow portion 4233 can be located at a position facing the circulating flow path portion 820. The inflow portion can be located at a position facing the air supply portion 8231. The inflow portion 4233 can be recessed from the rear panel 421 toward the rear to prevent interference with the air supply portion 8231. The upper side of the inflow portion 4233 can be connected to the flow portion 4231.

[0277] The laundry treatment apparatus of an embodiment of the disclosure can include a connector 850 connected with the air supply part 8231. The connector 850 can guide the hot air discharged from the air supply part 8231 to the flow part 4231. The connector 850 can be formed with a flow path inside thereof to guide the hot air discharged from the air supply part 4231 to the flow part 4231. That is, the connector 850 can form a flow path connecting the air supply part 8231 and the flow part 4231. The cross-sectional area of the flow path provided inside the connector 850 can be configured to increase the farther it is from the air supply part 8231.

[0278] The connector 850 can be located at a position facing the inflow part 4233. The inflow part 4233 can be formed to be recessed toward the rear to prevent interference with the connector 850. In addition, the top end of the connector 850 can be configured to separate the flow part 4231 and the inflow part 4233. That is, the hot air discharged from the connector 850 can flow into the flow part 4231, and be prevented from flowing into the inflow part 4233.

[0279] The connector 850 can be configured to uniformly supply hot air to the flow part 4231. The connector 850 can be configured to increase in width the farther it is from the air supply part 8231. The top end of the connector 850 can be disposed along the circumferential extension line of the flow outer circumferential part 4231a.

[0280] Accordingly, all of the hot air discharged from the connector 850 can be supplied to the flow part 4231 as a whole without moving to the inflow part 4233. The connector 850 can uniformly supply hot air to the inside of the drum by preventing the hot air from being concentrated on one side of the flow part 4231. This has the effect of improving the drying efficiency of laundry.

[0281] The connector 850 can be configured to increase in width the closer it is to the upstream side, so that the speed of the hot air moving along the connector 850 decreases in the flow direction. That is, the connector 850 can perform the function of a diffuser that adjusts the speed of the hot air. The connector 850 can prevent a situation in which the hot air is supplied only concentratedly to a specific portion of the drum by decreasing the speed of the hot air.

[0282] The inflow part 4233 configured to face the connector 850 and configured to prevent interference with the connector 850 can also be configured to increase in width the farther it is from the air supply part 8231 by the shape of the connector 850 as described above. By the shape of the inflow part 4233, the overall shape of the duct part 423 can be in the shape of “9” when viewed from the front.

[0283] The drum is configured to rotate in a drying course, and thus, the drum can be configured to be spaced apart from the flow part 4231 by a prescribed distance. Hot air can flow out through the spaced apart space.

[0284] Thus, the laundry treating apparatus can further include a sealing part 450 to prevent leakage of the hot air from the spaced apart space between the drum and the flow part 4231. The sealing part 450 can be provided along the outer periphery of the flow part 4231.

[0285] The sealing part 450 can include a first sealing member 451 provided along the outer periphery of the flow part 4231. The first sealing member 451 can be provided between the outer periphery of the drum and the outer periphery of the flow part 4231. In addition, the first sealing member 451 can be configured to be in contact with both the drum back surface 220 and the rear plate 420, thereby being able to more effectively prevent leakage.

[0286] On the other hand, the first sealing member 451 can be configured to be in contact with the front surface of the connection member 850. In addition, the first sealing member 451 can be configured to be in contact with the top end of the connection member 850. The connection member 850 can form a flow path for the hot air to flow together with the flow part 4231. Thus, the first sealing member 451 can be configured to be in contact with the connection member 850 to prevent leakage of the hot air from between the drum and the connection member 850.

[0287] The sealing part 450 can include a second sealing member 452 provided along the inner periphery of the flow part 4231. The second sealing member 452 can be provided between the inner periphery of the drum and the inner periphery of the flow part 4231. In addition, the second sealing member 452 can be configured to be in contact with both the drum back surface 220 and the rear plate 420. The second sealing member 452 can prevent the hot air moving along the flow part 4231 from being leaked toward the mounting part 425.

[0288] Since the drum 200 rotates in the operation course of the laundry treating apparatus, the sealing part 450 is continuously subjected to friction by the drum back surface 220. Thus, the sealing part 450 is preferably composed of a material capable of sealing between the drum back surface 220 and the flow part 4231, which does not degrade its performance even though subjected to the frictional force and frictional heat generated by the rotation.

[0289] Figure 9 A combined structure of a rear plate, a decelerator, and a motor part according to an embodiment of the present application is illustrated.

[0290] Referring to Figure 9 The decelerator 600 can be supported by the rear plate 420, and the motor part 500 can be combined with the decelerator 600. That is, the rear plate 420 can be configured to support both the decelerator 600 and the motor part 500.

[0291] A motor portion 500 providing rotational power and a reducer 600 reducing the power of the motor portion and transmitting the same to the drum can be provided behind the rear plate 420.

[0292] The reducer 600 can be provided in the rear plate 420 in a manner of being located inside the duct portion 423. The reducer 600 can be located at a radially inner side of the flow portion 4231 to prevent interference with the flow portion 4231.

[0293] A gear device inside the reducer 600 can be damaged by hot air of the hot air moving along the flow portion 4231. Accordingly, the flow portion 4231 and the reducer 600 can be configured to be spaced apart from each other by a prescribed distance.

[0294] The reducer 600 can be combined in a manner of penetrating the rear plate 420. Accordingly, the reducer 600 can be connected with the drum located in front of the rear plate 420.

[0295] The stator 510 can be combined with the reducer 600. The stator 510 can be combined with the reducer 600 and configured to be spaced apart from the rear plate 420. At this time, the reducer 600 can be located between the drum and the motor portion to support the drum and the motor portion in a manner of being spaced apart from the rear plate 420. That is, the reducer 600 can become a center supporting the drum and the motor portion.

[0296] On the other hand, the stator 510 can include a body 511 configured in a ring shape, a fixing rib 512 extending from an inner circumferential surface of the body 511 to be combined with a stator combining portion 613 of the reducer, a tooth 514 configured to extend from an outer circumferential surface along a circumference of the body 511 and to be wound with a coil, and a pole shoe 515 provided at a free end of the tooth 514 to prevent the coil from being separated.

[0297] The rotor 520 can include a rotor body 521 configured in a hollow shape of a cylinder. In addition, the rotor 520 can include a mounting body 522 recessed in a front direction from a back surface of the rotor body 521. The rotor 520 can be configured with a permanent magnet along an inner circumferential surface of the rotor body 521.

[0298] The rotor 520 can be combined with a driving shaft 530 to transmit rotational power of the rotor 520 to the outside through the driving shaft 530. The driving shaft 530 can be connected with the rotor 520 through a washer portion 540.

[0299] In addition, the motor portion 500 can include the washer portion 540 supporting the driving shaft 530. The washer portion 540 can include a washer combining body 541 combined with the rotor. The washer combining body 541 can be configured in a disc shape.

[0300] The washer portion 540 can include an accommodation body 542 which is accommodated in the rotor. The accommodation body 542 can be configured to protrude rearward from the washer coupling body 541. The washer portion 540 can include a shaft support hole 543 which is configured to pass through the center of the accommodation body 542. The driving shaft 530 can be inserted into the shaft support hole 543 and supported by the washer portion 540.

[0301] In addition, the washer portion 540 can include a washer coupling hole 5412 which is provided to pass through the washer coupling body 541. In addition, the mounting body 522 can include a rotor coupling hole 526 which is provided at a position corresponding to the washer coupling hole 5412. That is, the washer portion 540 and the rotor 520 can be coupled to each other by a coupling member which passes through the washer coupling hole 5412 and the rotor coupling hole 526 at the same time. That is, the washer portion 540 and the rotor 520 can be coupled to each other and rotate together.

[0302] In addition, the washer portion 540 can include a washer coupling protrusion 5411 which protrudes rearward from the washer coupling body 541. In addition, the mounting body 522 can include a washer protrusion accommodation hole 525 which is provided corresponding to the washer coupling protrusion 5411. The washer coupling protrusion 5411 can be inserted into the washer protrusion accommodation hole 525 to support the coupling of the washer portion 540 and the rotor 520.

[0303] In addition, the rotor 520 can include a rotor provision hole 524 which is configured to pass through the center of the mounting body 522. The rotor provision hole 524 can accommodate the accommodation body 542. Thereby, the washer portion 540 can rotate together with the driving shaft 530 using the rotor 520, and can firmly support the coupling of the driving shaft 530 and the rotor 520. Accordingly, it has an effect of being able to secure the durability and reliability of the entire motor portion 500.

[0304] Figure 10 A coupling structure of a reducer and a stator of an embodiment of the present application is shown from the rear.

[0305] The stator 510 can include a body body 511 which is fixed to the reducer 600 and is configured in a ring shape, a fixing rib 512 which extends from an inner circumferential surface of the body body 511 to be coupled to the stator fastening hole 615 of the reducer, a tooth 514 which is configured to extend from an outer circumferential surface along a circumferential edge of the body body 511 and is provided for a coil to be wound, a pole shoe 515 which is provided at a free end of the tooth 514 to prevent the coil from being separated, and a terminal (not shown) which controls to supply current to the coil.

[0306] The stator 510 can include an accommodation space 513 provided inside the body main body 511 through the body main body 511. The fixing ribs 512 can be provided at a predetermined angle apart from each other with the accommodation space 513 as a reference inside the body main body 511, and a fixing rib hole 5121 for mounting a fixing member can be provided at the inner side of the fixing ribs 512, so that the fixing rib hole 5121 is combined with a stator fastening hole 615 of a reducer by a fixing member such as a pin.

[0307] In the case where the stator 510 is directly combined with the reducer 600, a part of the reducer 600 can be accommodated in the stator 510. In particular, when the reducer 600 is accommodated in the stator 510, the thickness of the entire driving part including the reducer and the motor part is reduced, so that the volume of the drum can be more expanded.

[0308] To this end, the reducer 600 can be configured to have a diameter smaller than that of the body main body 511. That is, the maximum diameter of the first housing 610 and the second housing 620 can be smaller than that of the body main body 511. Thus, at least a part of the reducer 600 can be accommodated in the body main body 511. However, the stator coupling part 613 can be extended from the housing of the reducer to be able to overlap the fixing ribs 512. Thus, the stator coupling part 613 can be coupled with the fixing ribs 512, and a part of the first housing and the second housing 620 can be located inside the body main body 511.

[0309] Figure 11 The coupling of the reducer and the motor part according to an embodiment of the present application is illustrated.

[0310] The stator 510 can be coupled with the reducer 600. The stator coupling part 613 protruding to the outside from the housing of the reducer 600 can be coupled so that at least a part of the reducer is accommodated inside the body main body 511. Thus, the center of the body main body 511 and the driving shaft 530 and the center of the reducer 600 can always be kept coaxial.

[0311] On the other hand, the rotor 520 can be configured to accommodate the stator 510 in a state of being spaced apart from the pole piece 515 by a predetermined distance. In the rotor 520, since the driving shaft 530 is fixed to the reducer 600 accommodated in the body main body 511, the interval G1 of the rotor 520 and the stator 510 can always be maintained.

[0312] Accordingly, the rotor 520 is prevented from colliding with the stator 510 or being temporarily misaligned and rotated in the stator 510, so that noise or unnecessary vibration can be prevented from occurring.

[0313] On the other hand, an imaginary first diameter line K1 passing through the center of the decelerator 600 and the center of the driving shaft 530, an imaginary second diameter line K2 passing through the center of the body main body 511, and an imaginary third diameter line K3 passing through the center of the rotor 520 can all be configured at the rotation center of the decelerator 600.

[0314] Thus, the decelerator 600 itself becomes the rotation center of the driving shaft 530, and since the stator 510 is directly fixed to the decelerator 600, it is possible to prevent the driving shaft 530 from being misaligned with reference to the decelerator 600. As a result, it is possible to ensure the reliability of the decelerator 600.

[0315] Figure 12 is a perspective view showing a part of a base 800 of a laundry treating apparatus according to an embodiment of the present application.

[0316] Referring to Figure 12 , the base 800 can include a circulation flow path portion 820 provided at one side of the base 800 to circulate air of a drum. In addition, a device mounting portion 810 can be provided at the other side of the base 800, the device mounting portion 810 providing a space for mounting structures required for operation of a dryer. The device mounting portion 810 can be provided outside the circulation flow path portion 820.

[0317] In the existing dryer, the circulation flow path portion 820 is provided on the base 800, and a driving portion for rotating the drum 200 is also provided on the base 800. Since the driving portion occupies most of the mounting space of the base 800, the space in the device mounting portion 810 formed in the space of the base 800 other than the circulation flow path portion 820 is narrow, and thus it is not easy to mount structures of other laundry treating apparatuses.

[0318] However, in the laundry treating apparatus according to an embodiment of the present application, the motor portion 500 rotating the drum 200 can be spaced apart from the base 800 and disposed at the rear of the drum 200, and thus the space of the base 800 originally used to mount the motor portion 500 can be variously applied.

[0319] A compressor 930 for compressing refrigerant required for heat exchange can be provided in the device mounting portion 810. In addition, the base 800 can include a sump portion 860 disposed to be spaced apart from the compressor 930 and to collect condensed water generated in the circulation flow path portion 820. A control box 190 for controlling the compressor 930, the motor portion, etc. can be provided on the device mounting portion 810.

[0320] The control box 190 can be disposed on the base and be firmly supported. Also, a connection line for connecting the control box 190 and a structure controlled by the control box can be firmly supported by the base 800.

[0321] As another example, the water collecting portion 860 can not be disposed between the compressor 930 and the circulation flow path portion 820, but can be disposed to overlap the compressor 930 in the front-rear direction. Since the water collecting portion 860 can be located in a space in which a motor portion is disposed in the related art, it is possible to expand the volume of the water collecting portion 860. If the volume of the water collecting portion 860 is increased, it is possible to reduce the frequency of emptying collected condensed water, thereby improving the convenience of a user.

[0322] A side panel forming a side surface of a cabinet can be coupled to a side surface of the base 800. The side panel can include a left side panel 141 and a right side panel (not shown). The control box 190 can be disposed on the device mounting portion 810 and can be disposed to be adjacent to any one of the side panels.

[0323] The control box 190 can correspond to a portion that controls the overall operation of the laundry treating apparatus. Thus, it can be more likely that the control box 190 is checked or repaired.

[0324] In a case in which the control box 190 is disposed adjacent to the left side panel 141, a user can approach the control box 190 by only detaching the left side panel 141. Thus, there is an effect of increasing the convenience of maintenance.

[0325] In a case in which the left side panel 141 is detached, various structures such as the compressor 930 and the control box 190 can be easily approached. Thus, the left side panel 141 can be referred to as a service panel.

[0326] Figure 12 It is shown that the device mounting portion 810 is located on the left side of the base 800 and the control box 190 can be approached by only detaching the left side panel 141. However, it is not limited thereto, and if the circulation flow path portion 820 is formed on the left side and the device mounting portion 810 is formed on the right side, the control box or the compressor, etc. can be repaired or checked by detaching a second side panel (not shown).

[0327] On the other hand, the circulation flow path portion 820 can further include a duct cover portion 830 located on an upper side of the circulation flow path portion 820 and forming a flow path through which air discharged from a drum moves. The duct cover portion 830 can be coupled to an open top surface of the circulation flow path portion 820.

[0328] The inflow duct 821 and the moving duct 822 are open at the top surface, so that air can flow in and out through the open top surface. The duct cover portion 830 can shield the open top surface of the moving duct 822. Accordingly, the duct cover portion 830 can cause air of the drum to flow in through the inflow duct 821, and can prevent air flowing into the inflow duct 821 from flowing out through the open top surface of the moving duct 822. That is, the duct cover portion 830 can form a surface that guides air flowing in through the inflow duct 821 to a flow path of the exhaust duct 823.

[0329] The exhaust duct 823 can include a blowing portion 8231 that blows air to the outside of the exhaust duct 823. The blowing portion 8231 can exhaust air flowing through the inflow duct 821 and the moving duct 822 to the outside of the exhaust duct 823.

[0330] The blowing portion 8231 can provide a space for installing a circulation flow path fan 950 that circulates air inside the drum. The circulation flow path fan 950 can increase the circulation speed of air by forcibly flowing air, and increase the drying speed of laundry, thereby having an effect of shortening the required time.

[0331] When the circulation flow path fan 950 rotates, air can flow in a manner of being exhausted through an opening portion formed at the upper side of the blowing portion 8231. The air exhausted from the blowing portion 8231 can re-enter the inside of the drum, thereby being used for drying laundry.

[0332] The circulation flow path fan 950 can apply various forms of fans. As an example, a silo fan can be applied such that air flows in along the rotation axis direction and exhausts air in the radial direction. However, it is not limited thereto, and various fans can be used to generate air flow according to design purposes.

[0333] The duct cover portion 830 can include a communication cover body 8312 that is combined with the upper side of the inflow duct 821, and a shielding cover body 8311 that is combined with the upper side of the moving duct 822. The shielding cover body 8311 can extend from the communication cover body 8312, and the shielding cover body 8311 can be integrated with the communication cover body 8312.

[0334] The communication cover body 8312 can include an inflow communication hole 8314 that communicates the drum and the inflow duct 821. Even though the communication cover body 8312 is combined with the inflow duct 821, the inflow communication hole 8314 can guide air exhausted from the drum to the inflow duct 821.

[0335] In addition, since the shielding cover body 8311 can shield the top surface of the moving duct 822, air flowing into the inflow duct 821 can be guided to the exhaust duct 823 without flowing out to the outside of the circulating flow path portion 820 through the moving duct 822.

[0336] The shielding cover body 8311 can include a washing flow path portion 833 provided at the top surface of the shielding cover body 8311 to enable water to flow. The washing flow path portion 833 can receive water and spray the water toward the first heat exchanger located at the lower side of the duct cover portion 830.

[0337] A cover penetration hole 8313 penetrating the shielding cover body 8311 upward and downward can be provided at the downstream side of the washing flow path portion 833. Water moving along the washing flow path portion 833 can be sprayed to the lower side of the shielding cover body 8311 through the cover penetration hole 8313.

[0338] A first heat exchanger dehumidifying air discharged from the drum can be provided at the lower portion of the cover penetration hole 8313. Accordingly, water passing through the cover penetration hole 8313 can be sprayed toward the first heat exchanger to wash the first heat exchanger.

[0339] A nozzle cover portion can be coupled at the upper side of the washing flow path portion 833. The nozzle cover portion can shield the open top surface of the washing flow path portion 833. The nozzle cover portion can prevent air moving along the moving duct 822 from leaking through the cover penetration hole 8313. In addition, the nozzle cover portion can prevent water moving along the washing flow path portion 833 from being scattered to the outside by shielding the top surface of the washing flow path portion 833.

[0340] Differently from this, the circulating flow path portion 820 can further include a duct filter (not shown) provided in front of the first heat exchanger to filter impurities of air passing through the inflow duct 821. The duct filter (not shown) can be disposed between the inflow duct 821 and the first heat exchanger to prevent impurities from being stacked on the front surface of the first heat exchanger, thereby enabling the drying efficiency and heat exchange efficiency of the first heat exchanger to be improved.

[0341] In the case where impurities are stacked on the duct filter (not shown), circulation of air passing through the inflow duct 821 and the moving duct 822 can be hindered. To solve the problem as described above, the washing flow path portion 833 can spray water toward the duct filter (not shown), thereby removing impurities stacked on the duct filter (not shown) using water pressure.

[0342] However, for convenience of explanation, a laundry treatment apparatus configured to omit the duct filter (not shown) will be described below as a center.

[0343] The laundry treating apparatus can further include a flow path switching valve 870 combined with the washing flow path part 833 to supply water required for washing to the washing flow path part 833. The flow path switching valve 870 can be connected with a water supply source to selectively supply water to the washing flow path part 833. The water supply source can include a water collecting part 860.

[0344] The flow path switching valve 870 can be connected with the water collecting part 860 through a hose to guide water collected in the water collecting part 860 to the washing flow path part 833. The flow path switching valve 870 can guide water collected in the water collecting part 860 to the water storage tank 120 (refer to Figure 1 ).

[0345] Figure 13 is an exploded perspective view showing the pipe cover part and the water collecting cover separated from the base of the Figure 12 .

[0346] Referring to Figure 13 , the first heat exchanger 910 and the second heat exchanger 920, which sequentially perform heat exchange with air inside the drum 200, can be disposed in the lower portion of the pipe cover part 830 spaced apart from each other in the front-rear direction. Air inside the drum 200 flowing into the inflow pipe 821 can perform heat exchange in the first heat exchanger 910 and be dehumidified, and the dehumidified air can perform heat exchange in the second heat exchanger 920 and be heated. The heated air can be resupplied to the inside of the drum 200 through the discharge pipe 823.

[0347] The circulating flow path part 820 can further include a water cover 826 disposed between the first heat exchanger 910 and the bottom face of the moving pipe 822. The water cover 826 can be configured to be supported by the moving pipe 822.

[0348] The water cover 826 can be positioned in the lower portion of the first heat exchanger 910 and configured to support the bottom face of the first heat exchanger 910. The water cover 826 can support the first heat exchanger 910 in a manner spaced apart from the bottom face of the moving pipe 822.

[0349] In the first heat exchanger 910, wet steam discharged from the drum 200 is condensed, and thus condensed water can be generated. If the condensed water fails to be discharged from the inside of the laundry treating apparatus and remains, there is a problem in that odor is generated or drying efficiency is reduced. To this end, it is required to collect the condensed water in a state spaced apart from the first heat exchanger 910 or the second heat exchanger 920 and discharge the collected condensed water.

[0350] The water cover 826 can support the first heat exchanger 910 in a manner spaced apart from the bottom surface of the moving duct 822, thereby forming a space between the bottom surface of the moving duct 822 and the water cover 826. The condensed water can flow along the space formed by the water cover 826 to the water collecting portion 860.

[0351] The air dehumidified by the first heat exchanger 910 is heated in the second heat exchanger 920, the air passing through the second heat exchanger 920 has a small amount of water content, and as it is heated, the amount of saturated water vapor increases, so that it is not easy to generate condensed water. Therefore, the water cover 826 can be located at a lower surface adjacent to the first heat exchanger 910, and the water cover 826 can be configured to be spaced apart from the second heat exchanger 920.

[0352] Since Figure 13 Only a portion of the top surface of the water cover 826 is shown in FIG. 8, and thus the shape of the flow path formed by the water cover 826 and the detailed structure of the water cover 826 will be described later in FIG. 9.

[0353] On the other hand, the base 800 can include a water collecting portion 860 configured to be spaced apart from the circulating flow path portion 820 to collect condensed water generated in the circulating flow path portion 820. The water collecting portion 860 can include a water collecting body 862 forming a space for collecting condensed water.

[0354] The water collecting portion 860 can further include a water collecting cover 863 shielding an open top surface of the water collecting body 862. A structure susceptible to moisture can be provided at the periphery of the water collecting portion 860. Therefore, it is necessary to prevent the condensed water collected in the water collecting body 862 from being scattered to the outside. The water collecting cover 863 can be combined with the water collecting body 862 to prevent the condensed water from leaking from the top surface of the water collecting body 862.

[0355] In addition, the water collecting portion 860 can include a pump moving the condensed water collected inside the water collecting body 862 to the outside. In order for the pump to function, the inside of the water collecting body 862 must be sufficiently sealed. The water collecting cover 863 can improve the reliability of the pump by sealing the inside of the water collecting body 862.

[0356] The water collecting cover 863 can include a water collecting cover body 8631 forming a shielding surface of the water collecting body 862. In addition, the water collecting cover 863 can include at least one of a support body 8635 configured to support the water collecting cover body 8631 and a fastening hook 8636 configured to combine the water collecting cover body 8631 with the water collecting body 862.

[0357] The support body 8635 can be protruded from the periphery of the water collecting cap body 8631 to be seated to the base. The fastening hook 8636 can be formed protruding from the water collecting cap body 8631. The fastening hook 8636 can firmly fix the water collecting cap body 8631 to the water collecting body 862. The fastening hook 8636 can be inserted into the hook hole to be fixed.

[0358] The condensed water generated in the circulating flow path part 820 inside the water collecting body 862 is collected. And, since the top surface of the water collecting body 862 is open, the condensed water can be scattered to the outside. But, since the water collecting body 862 is located adjacent to the control box 190, the compressor 930, etc., if the condensed water is scattered to the outside of the water collecting body 862, the malfunction of the mechanical device can occur.

[0359] The water collecting cap 863 can prevent the condensed water from being scattered by shielding the open top surface of the water collecting body 862 with the water collecting cap body 8631, and the support body 8635 and the fastening hook 8636 can firmly fix the water collecting cap body 9631 to the water collecting body 862. Thus, the malfunction of the device due to the scattering of the condensed water can be prevented.

[0360] In addition, the water collecting cap 863 can include a pump mounting part 8634 configured to be inserted by the pump through the water collecting cap body 8631. In addition, the water collecting cap 863 can include a drain flow path 8637 protruding upward from the water collecting cap body 8631 and configured to be in a pipe shape to communicate the inside and the outside of the water collecting body 862.

[0361] The pump mounting part 8634 can be provided with a pump configured to move the condensed water collected in the inside of the water collecting body 862 to the outside of the water collecting body 862. When the pump is operated, the condensed water stored in the inside of the water collecting body 862 can be discharged through the drain flow path 8637.

[0362] The drain flow path 8637 can be connected with a hose to guide the discharged condensed water to the outside of the water collecting body 862. One end of the hose can be combined with the drain flow path 8637, and the other end can be connected with the flow path switching valve 870. But, it is not limited thereto, and the other end of the hose can be located outside the cabinet to directly discharge the condensed water to the outside of the cabinet. The other end of the hose can be connected with the water storage tank 120 (refer to Figure 1 ) located at the upper portion of the cabinet to guide the condensed water collected in the water collecting body 862 to the water storage tank 120.

[0363] The water collection cover 863 may further include a return flow path 8638, which is separated from the drainage flow path 8637 and connects the interior and exterior of the water collection body 862. The return flow path 8638 may be configured to connect the water collection body 862 to a water storage tank. The return flow path 8638 can guide water from the water storage tank back to the water collection body 862.

[0364] The return flow path 8638 can be connected via a hose to the water storage tank 120 formed at the top of the housing (see reference). Figure 1 (Connection). To prevent water from overflowing from the water storage tank, when the tank is full, the water stored in the tank can be moved back to the water collection body 862 via a hose connecting the return flow path 8638 and the water storage tank. This improves user convenience by reducing the frequency of direct drainage.

[0365] Alternatively, it may include a flow path switching valve 870 for switching the flow path of condensate collected in the water collection section 860. The pump can be connected to the flow path switching valve 870 via a hose. Water stored in the water collection body 862 can be moved by the pump to the flow path switching valve 870. The flow path switching valve 870 can guide the moving water to various paths.

[0366] A flow path switching valve 870 can be connected to a cleaning flow path section 833 to move the water to the cleaning flow path section 833. The water guided to the cleaning flow path section 833 can be used to clean the first heat exchanger.

[0367] Additionally, the flow path switching valve 870 can be connected to the water storage tank 120 via a hose to guide the condensate moving from the water collection body 862 to the water storage tank 120. Users can drain the water directly by removing the water storage tank containing the condensate.

[0368] The flow path switching valve 870 can be controlled by the control box 190 and can operate differently depending on the operating time of the garment handling device. For example, when the first heat exchanger 910 in the drying cycle has finished operating, the control box 190 can control the flow path switching valve 870 to guide the condensate to the washing flow path section 833. Alternatively, when the first heat exchanger 910 has finished washing, the control box 190 can control the flow path switching valve 870 to guide the condensate to the water storage tank 120.

[0369] On the other hand, as described above, in order to make the pump operate normally, it is preferable to seal the inside of the space in which the pump drains. Since the water collecting cover 863 can be firmly coupled with the water collecting body 862 using the support body 8635 and the fastening hook 8636, it is possible to easily seal the space for storing the condensed water. Thus, it is possible to improve the operation reliability of the pump 861. A seal can be additionally provided at the portion where the water collecting cover 863 and the water collecting body 862 are coupled, to improve the sealing of the space.

[0370] On the other hand, the water collecting cover 863 can be configured to seal the inside of the water collecting body 862, and can be provided to the water collecting body 862 in a detachable manner. Foreign matter such as lint included in the condensed water generated by the first heat exchanger 910 can flow into the inside of the water collecting body 862. In the case where foreign matter having a large particle size flows in, a problem in which the operation of the pump is interfered can occur.

[0371] Thus, in order to remove foreign matter flowing into the inside of the water collecting body 862 as needed, the water collecting cover 863 needs to be detached. Thus, the water collecting cover 863 can be provided to the water collecting body 862 in a detachable manner. At this time, it has an effect in that the water collecting cover 863 can be easily detached from the water collecting body 862 using the fastening hook 8636.

[0372] That is, in a general use environment, the support body 8635 and the fastening hook 8636 can prevent the condensed water from being scattered to the outside by firmly shielding the open top surface of the water collecting body 862.

[0373] On the other hand, in the case where the water collecting cover 863 needs to be detached in order to remove foreign matter stacked on the water collecting body 862, the water collecting cover can be easily detached using the fastening hook 8636.

[0374] On the other hand, the duct cover portion 830 can include a cover mounting hook 8391 formed along the circumference of the duct cover portion 830, and the circulation flow path portion 820 can include a duct protrusion 824 configured to protrude along the circumference of the circulation flow path portion 820 so as to be fastened to the cover mounting hook 8391.

[0375] The cover mounting hook 8391 can be coupled with the duct protrusion 824 to couple the duct cover portion 830 with the circulation flow path portion 820. That is, the duct cover portion 830 can be firmly fastened to the duct protrusion 824 using the cover mounting hook 8391 in a state of being seated on the periphery of the inflow duct 821 and the movement duct 822.

[0376] A seal is additionally provided at the contact surface of the duct cover 830 and the circulation flow path portion 820, thereby preventing air from flowing from the inside of the circulation flow path portion 820 to the outside.

[0377] Figure 14 FIG. 8 is a cross-sectional view illustrating an arrangement relationship between a drum and a circulation flow path portion of a laundry treating apparatus according to an embodiment of the present application. Here, the contents overlapping with the structures explained in FIGS. 1 to 7 will be omitted. Figure 13

[0378] The cabinet 100 can include a first side panel 141 positioned at one side of the drum 200 to form one side surface, and a second side panel 142 positioned at the other side of the drum 200 to form the other side surface.

[0379] In this case, the circulation flow path portion 820 can be disposed closer to one of the first side panel 141 and the second side panel 142. The water collecting portion 860 can be disposed closer to the other of the first side panel 141 and the second side panel 142.

[0380] For example, the circulation flow path portion 820 can be disposed closer to the second side panel 142 than the first side panel 141, and the moving duct 822 and the duct cover 830 can be disposed closer to the second side panel 142 than the first side panel 141. The first side panel 141 can be a left side surface, and the second side panel 142 can be a right side surface, with reference to the drum 200.

[0381] Accordingly, the water collecting portion 860 can be disposed outside the circulation flow path portion 820, apart from the circulation flow path portion 820, and the water collecting portion 860 can be disposed between the second side panel 142 and the circulation flow path portion 820.

[0382] On the other hand, the flow path switching valve 870 can be disposed in combination with the circulation flow path portion 820 to communicate with the washing flow path portion 833 and deliver condensed water to the washing flow path portion 833. At this time, since the flow path switching valve 870 extends by a predetermined length L9 in combination with the circulation flow path portion 820, there is a possibility that the flow path switching valve 870 interferes with the drum 200 depending on the arrangement of the flow path switching valve 870.

[0383] ​To solve such a problem, the flow path switching valve 870 can be configured lower than a top surface of the duct cover 830 and face a side surface of the moving duct 822. As an example, the flow path switching valve 870 can be configured to be disposed between the circulating flow path portion 820 and the first side panel 141 and face the water collecting portion 860. An upper end of the flow path switching valve 870 can be configured to be lower than the top surface of the duct cover 830.

[0384] Thereby, the flow path switching valve 870 can avoid interference with the drum 200, and a user can easily repair and maintain the flow path switching valve 870 by separating the first side panel 141 without separating the drum 200.

[0385] In addition, the duct cover 830 can include a valve connection portion 838 extending toward the water collecting portion 860 to face the water collecting portion 860. The valve connection portion 838 can be configured to be disposed at an upper portion of the water collecting portion 860 and can be configured to be parallel to the water collecting portion 860.

[0386] The flow path switching valve 870 can extend toward the water collecting portion 860 in conjunction with a bottom surface of the valve connection portion 838. The cleaning flow path portion 833 can be configured to have one end formed at a top surface of the valve connection portion 838 to communicate with the flow path switching valve 870.

[0387] By the flow path switching valve 870 in conjunction with the bottom surface of the valve connection portion 838, interference of the flow path switching valve 870 with the drum 200 can be further prevented. In addition, in the laundry treating apparatus, a radius R of the drum 200 can be more expanded within a range in which interference with the flow path switching valve 870 is prevented, and the flow path switching valve 870 can be freely disposed according to a position of the valve connection portion 838.

[0388] Hereinafter, a structure of the flow path switching valve 870 will be described in detail. The flow path switching valve 870 can include a supply switching portion 871 communicating with the pump 861 to receive the water from the pump 861 and a switching connection portion 879 communicating with the supply switching portion 871, in conjunction with the duct cover 830, to deliver the water to the cleaning flow path portion 833.

[0389] In addition, the flow path switching valve 870 can further include a transfer portion 872 disposed between the supply switching portion 871 and the switching connection portion 879. The transfer portion 872 can be configured to be coupled with the supply switching portion 871 and the switching connection portion 879, respectively, and to guide the water received from the supply switching portion 871 toward the switching connection portion 879. In other words, the supply switching portion 871, the transfer portion 872, and the switching connection portion 879 can be coupled in this order in the direction of movement of the condensed water.

[0390] Here, the switching connection portion 879 can be coupled with the valve connection portion 838 to extend toward the water collecting portion 860, and the switching connection portion 879 can be configured to face the water collecting body 862. In addition, the switching connection portion 879 can be coupled with the bottom surface of the valve connection portion 838 to communicate with the purge flow path portion 833 and to transfer the condensed water to the purge flow path portion 833.

[0391] On the other hand, the water collecting portion 860 can include a drain flow path 8637 protruding upward from the water collecting cover 863 to communicate the outside of the water collecting cover 863 with the water collecting body 862, and a first water collecting discharge pipe 8911a connecting the drain flow path 8637 with the flow path switching valve 870 to allow the condensed water to move from the pump 861 toward the flow path switching valve 870. The first water collecting discharge pipe 8911a can correspond to a passage for the condensed water to move from the pump 861 toward the flow path switching valve 870.

[0392] As an example, the supply switching portion 871 can be connected with the first water collecting discharge pipe 8911a and receive the condensed water from the pump 861 through the first water collecting discharge pipe 8911a, and the condensed water supplied to the supply switching portion 871 can be transferred toward the transfer portion 872 and the switching connection portion 879.

[0393] As the flow path switching valve 870 extends from the valve connection portion 838 toward the water collecting portion 860, the supply switching portion 871 can be disposed at an upper portion of the water collecting portion 860 to face the water collecting portion 860.

[0394] Accordingly, it is possible to shorten the distance between the supply switching portion 871 and the pump 861, and to prevent the condensed water from remaining in the first water collecting discharge pipe 8911a by shortening the extension length of the first water collecting discharge pipe 8911a connecting the pump 861 with the supply switching portion 871.

[0395] Figure 15 FIG. 6 is a perspective view illustrating a purge flow path portion provided on a top surface of a duct cover portion in a laundry treating apparatus according to an embodiment of the present application.

[0396] The duct cover portion 830 can include a shielding cover body 8311 combined with an upper portion of the moving duct 822 to shield the first heat exchanger 910 and the second heat exchanger 920, and a communication cover body 8312 extending forward from the shielding cover body 8311 to be combined with an upper portion of the inflow duct 821.

[0397] The shielding cover body 8311 can be configured to shield an open top surface of the moving duct 822, and the communication cover body 8312 can be configured to be seated on a top surface of the inflow duct 821.

[0398] At this time, the shielding cover body 8311 and the communication cover body 8312 can be formed as one body. Thereby, an assembly process of the duct cover portion 830 can be simplified, and air inside the moving duct 822 and the inflow duct 821 can be prevented from flowing out between the shielding cover body 8311 and the communication cover body 8312.

[0399] In addition, the communication cover body 8312 can include an inflow communication hole 8314 penetrating one surface of the communication cover body 8312 to communicate the drum 200 and the inflow duct 821. The inflow communication hole 8314 can communicate with the duct communication hole 417 illustrated in FIG. 17, and thereby air discharged from the drum 200 can flow in through the inflow communication hole 8314. Figure 2

[0400] A width of the inflow duct 821 can be greater than a width of the moving duct 822, and thus a width of the communication cover body 8312 seated on a top surface of the inflow duct 821 can be greater than a width of the shielding cover body 8311.

[0401] In addition, a width of the inflow communication hole 8314 formed in the communication cover body 8312 can be greater than a width of the shielding cover body 8311, and thereby air inside the drum 200 can smoothly flow in to the inflow communication hole 8314 in communication with the drum 200.

[0402] A diameter of the inflow communication hole 8314 can be greater than a diameter of the shielding cover body 8311, one end of the inflow communication hole 8314 can be configured to be parallel to the shielding cover body 8311, and the other end of the inflow communication hole 8314 can be configured to protrude toward the switching connection portion 879.

[0403] On the other hand, water supplied to the cleaning flow path portion 833 through the switching connection portion 879 moves along a top surface of the shielding cover body 8311 and is discharged to the first heat exchanger 910, and thereby foreign matter attached to a front surface of the first heat exchanger 910 can be removed. ​

[0404] Therefore, the shielding cover body 8311 may include a cover through hole 8313, which penetrates the top surface of the shielding cover body 8311 and faces at least a portion of the first heat exchanger 910. The cover through hole 8313 may be disposed at the end of the cleaning flow path 833, thereby communicating between the cleaning flow path 833 and the first heat exchanger 910.

[0405] The cover through hole 8313 can serve as the outlet of the cleaning flow path 833, through which water moving along the cleaning flow path 833 can be sprayed into the first heat exchanger 910.

[0406] Therefore, without the need for the user to separate the first heat exchanger 910 and perform separate cleaning, the impurities attached to the first heat exchanger 910 can be removed by the water discharged from the cleaning flow path 833 through the cover through hole 8313.

[0407] The through hole 8313 can be provided corresponding to the width direction of the cover body 8311, and can be configured to be parallel to the extending direction of the valve connection portion 838. The width W5 of the through hole 8313 can be smaller than the width of the cover body 8311, and can be parallel to the width direction of the valve connection portion 838. Figure 14 The width of the first heat exchanger 910 shown is correspondingly formed.

[0408] On the other hand, the conversion connection 879 can be configured to connect with... Figure 14 The transfer section 872 shown is connected to and transfers water to the cleaning flow path section 833. For this purpose, the conversion connection section 879 may include: connecting supply flow paths 8791a, 8791b, and 8791c, communicating with the transfer section 872, and receiving water from the transfer section 872. The supply flow paths 8791a, 8791b, and 8791c may pass through the valve connection section 838 and communicate with the cleaning flow path section 833, thereby transferring the condensate received from the transfer section 872 to the cleaning flow path section 833.

[0409] Additionally, the cleaning flow path 833 may include a valve connecting hole 8382, which penetrates the bottom surface of the cleaning flow path 833 and communicates with the connecting supply flow paths 8791a, 8791b, and 8791c. Condensate supplied from the connecting supply flow paths 8791a, 8791b, and 8791c can flow into the cleaning flow path 833 through the valve connecting hole 8382. The valve connecting hole 8382 may be disposed on the top surface of the valve connection portion 838 and may be disposed on the top surface of the shielding cover body 8311 along the extending direction of the connecting supply flow paths 8791a, 8791b, and 8791c.

[0410] On the other hand, the purge flow path part 833 can be disposed on the top surface of the shield cover body 8311 to guide water flowing from the valve communication hole 8382 to the cover through hole 8313. That is, the purge flow path part 833 can be disposed to extend from the valve communication hole 8382 to the cover through hole 8313. The valve communication hole 8382 can correspond to the start point of the purge flow path part 833, and the cover through hole 8313 can correspond to the end point of the purge flow path part 833.

[0411] For example, one end of the purge flow path part 833 can be disposed on the top surface of the valve connection part 838, and the other end can be connected to the cover through hole 8313. In addition, one end of the purge flow path part 833 can extend toward the valve connection part 838, and the other end can extend toward the cover through hole 8313.

[0412] On the other hand, condensed water supplied to the purge flow path part 833 through the valve communication hole 8382 can rub against the inner surface of the purge flow path part 833 during movement of the purge flow path part 833, and the flow rate thereof can gradually decrease. Due to this, the condensed water inside the purge flow path part 833 can remain in the purge flow path part 833 without being promptly discharged.

[0413] To this end, the shield cover body 8311 can include an inclined surface 8316 extending obliquely forward from a portion of the top surface of the shield cover body 8311. At least a portion of the purge flow path part 833 can be disposed on the inclined surface 8316.

[0414] Due to this, the amount of residual water that fails to be discharged from the purge flow path part 833 and remains can be minimized. In addition, the flow rate of water moving along the inclined surface 8316 can naturally increase, and thus impurities formed on the first heat exchanger 910 can be removed.

[0415] As an example, the inclined surface 8316 can include a first inclined surface 8316a extending obliquely forward from the top surface of the shield cover body 8311, and a second inclined surface 8316b extending obliquely from the first inclined surface 8316a toward the communication cover body 8312. The first inclined surface 8316a can extend more obliquely than the second inclined surface 8316b.

[0416] The purge flow path part 833 can include a guide flow path 8331 communicating with the valve communication hole 8382 to supply water from the valve communication hole 8382, and a discharge flow path 8332 connected to the guide flow path 8331 to extend toward the cover through hole 8313.

[0417] The guide flow path 8331 can be disposed on a top surface of the cover body 8311 formed higher than the inclined surface 8316, and the discharge flow path 8332 can be disposed on the inclined surface 8316.

[0418] In addition, the discharge flow path 8332 can include a first discharge flow path 8332a connected to the guide flow path 8331 and disposed on the first inclined surface 8316a, and a second discharge flow path 8332b connected to the first discharge flow path 8332a and disposed on the second inclined surface 8316b.

[0419] One end of the guide flow path 8331 can be disposed on a top surface of the valve connection portion 838 and extend toward the first inclined surface 8316a, and one end of the first discharge flow path 8332a can be in communication with the guide flow path 8331 and the other end can be in communication with the second discharge flow path 8332b, whereby water moving in the guide flow path 8331 can be directed to the second discharge flow path 8332b.

[0420] One end of the second discharge flow path 8332b can be in communication with the first discharge flow path 8332a and the other end can be connected to the cover through hole 8313, whereby water moving in the first discharge flow path 8332a can be directed to the cover through hole 8313.

[0421] Accordingly, the flow rate of water supplied to the guide flow path 8331 from the valve communication hole 8382 can naturally increase during passage through the first discharge flow path 8332a and the second discharge flow path 8332b. In other words, as the first discharge flow path 8332a and the second discharge flow path 8332b extend obliquely, the flow rate of water moving from the guide flow path 8331 to the cover through hole 8313 can naturally increase.

[0422] In addition, as water inside the cleaning flow path portion 833 moves along the first discharge flow path 8332a and the second discharge flow path 8332b to the cover through hole 8313, it is possible to prevent water inside the cleaning flow path portion 833 from remaining inside the cleaning flow path portion 833 without being timely discharged to the cover through hole 8313.

[0423] On the other hand, as liquid has a property that its diameter gradually decreases as the flow rate increases with movement, water inside the cleaning flow path portion 833 can not be uniformly dispersed at the end of the cleaning flow path portion 833. This can result in concentrated discharge only in a specific area in the cover through hole 8313, and can result in water not being uniformly supplied to the surface of the first heat exchanger 910.

[0424] Accordingly, the plurality of washing flow path portions 833 can be provided on the top surface of the cover main body 8311. The ends of the plurality of washing flow path portions 833 can be connected to the cover penetration hole 8313, respectively. Accordingly, the width of the end of any one of the plurality of washing flow path portions 833 can be smaller than the width of the end of the washing flow path portion 833 when the washing flow path portion 833 is provided as a single washing flow path portion.

[0425] The washing flow path portion 833 can include a first washing flow path 833a provided at one end of the plurality of washing flow path portions 833 closest to the cover main body 8311, a second washing flow path 833b provided at the other end of the plurality of washing flow path portions 833 closest to the cover main body 8311, and a third washing flow path 833c provided between the first washing flow path 833a and the second washing flow path 833b.

[0426] The end of the first washing flow path 833a can be connected to one end of the cover penetration hole 8313, and the end of the second washing flow path 833b can be connected to the other end of the cover penetration hole 8313.

[0427] The cover penetration hole 8313 can be connected to the ends of the first washing flow path 833a, the second washing flow path 833b, and the third washing flow path 833c.

[0428] In addition, the widths of the first washing flow path 833a, the second washing flow path 833b, and the third washing flow path 833c can be uniform with each other, but if it is not easy to disperse water to a specific area in the structure of the washing flow path portion 833, the widths of the first washing flow path 833a, the second washing flow path 833b, and the third washing flow path 833c can be different from each other.

[0429] In addition, one end of the first washing flow path 833a, the second washing flow path 833b, and the third washing flow path 833c can contact each other on the top surface of the valve connection portion 838, and can be separated from each other and extended in the moving direction of the condensed water. The other end of the first washing flow path 833a, the second washing flow path 833b, and the third washing flow path 833c can be extended to the cover penetration hole 8313.

[0430] In addition, Figure 14 The flow path switching valve 870 can be configured to communicate with the first washing flow path 833a, the second washing flow path 833b, and the third washing flow path 833c and selectively supply water to the first washing flow path 833a, the second washing flow path 833b, and the third washing flow path 833c.

[0431] Specifically, the number of the valve communication holes 8382 can correspond to the number of the plurality of the purge flow path portions 833, and the number of the connection supply flow paths 8791a, 8791b, 8791c can correspond to the number of the purge flow path portions 833.

[0432] The connection supply flow path 8791 can include a first connection supply flow path 8791a communicating with the first purge flow path 833a, a second connection supply flow path 8791b communicating with the second purge flow path 833b, and a third connection supply flow path 8791c communicating with the third purge flow path 833c.

[0433] The first connection supply flow path 8791a, the second connection supply flow path 8791b, and the third connection supply flow path 8791c can be selectively supplied with condensed water according to Figure 14 The flow path switching valve 870 is shown to selectively supply condensed water to the supply switching portion 871. Thus, water is selectively supplied to any one of the first connection supply flow path 8791a, the second connection supply flow path 8791b, and the third connection supply flow path 8791c, and sequentially supplied to any one of the plurality of the purge flow path portions 833 and discharged from the cover through hole 8313.

[0434] Thus, the water pressure of water discharged from any one of the plurality of the purge flow path portions 833 can be greater than the water pressure when condensed water is supplied from the flow path switching valve 870 to all of the plurality of the purge flow path portions 833. As the pressure of water discharged from the purge flow path portions 833 increases, impurities generated in the first heat exchanger 910 can be perfectly removed.

[0435] On the other hand, the purge flow path portion 833 can include a flow path forming portion 834 forming a flow path through which water flowing into the valve communication hole 8382 can move toward the cover through hole 8313. The flow path forming portion 834 can protrude from the top surface of the shield cover body 8311 and be formed integrally with the shield cover body 8311.

[0436] Thus, the purge flow path portion 833 does not need to be additionally combined with the shield cover body 8311, and thus the manufacturing cost of the pipe cover portion 830 can be reduced, and the assembly process can be simplified.

[0437] The flow path forming portion 834 can extend from the valve communication hole 8382 toward the cover through hole 8313.

[0438] That is, the flow path forming portion 834 can form the inner circumferential surface of the purge flow path portion 833. Specifically, the flow path forming portion 834 can be configured to form the inner circumferential surface of the guide flow path 8331 and the inner circumferential surface of the discharge flow path 8332. In addition, the flow path forming portion 834 can be configured to form the inner circumferential surface of the first discharge flow path 8332a and the second discharge flow path 8332b.

[0439] On the other hand, the purge flow path portion 833 can include a flow path discharge rib 835 configured to direct water discharged from the purge flow path portion 833 toward the first heat exchanger 910.

[0440] The flow path discharge rib 835 can extend forward from the end of the second discharge flow path 8332b. The flow path discharge rib 835 can extend downward, and the end of the flow path discharge rib 835 can be located at the cover through hole 8313 and can further extend toward the first heat exchanger 910. Thereby, water discharged from the purge flow path portion 833 can constantly move toward the first heat exchanger 910 along the flow path discharge rib 835.

[0441] Figure 16 is a top view of a duct cover portion of a laundry treating apparatus according to an embodiment of the disclosure, in which a purge flow path portion is provided.

[0442] The flow rate of the condensed water flowing into the guide flow path 8331 through the valve communication hole 8382 can naturally increase during the process of passing through the first discharge flow path 8332a and the second discharge flow path 8332b. Since a liquid has a property that its diameter gradually decreases as the flow rate becomes faster as it moves, the purge flow path portion 833 is configured to increase in width in the direction in which the condensed water moves, thereby being able to guide the condensed water to spread wider at the end.

[0443] Specifically, the guide flow path 8331 can be configured to increase in width t1 from the valve communication hole 8382 toward the first discharge flow path 8332a.

[0444] In addition, the width of the first discharge flow path 8332a can be greater than the width of the guide flow path 8331, thereby guiding water flowing into the first discharge flow path 8332a from the guide flow path 8331 to be uniformly discharged. The width t2 of the first discharge flow path 8332a can be greater than the width t1 of the guide flow path 8331.

[0445] Further, the width of the second discharge flow path 8332b can be greater than the width of the first discharge flow path 8332a, thereby causing water flowing from the first discharge flow path 8332a to the second discharge flow path 8332b to be discharged uniformly. The width t3 of the second discharge flow path 8332b can be greater than the width t2 of the first discharge flow path 8332a.

[0446] Further, the widths of the first discharge flow path 8332a and the second discharge flow path 8332b can increase in the direction of movement of the water.

[0447] As a result, the cleaning flow path portion 833 can spray water uniformly toward the front surface of the first heat exchanger 910, and thus water can be supplied uniformly to the entire first heat exchanger 910.

[0448] On the other hand, the pressure of water discharged from the valve communication hole 8382 can decrease as the water moves farther from the cover penetration hole 8313, and the thickness of the flow path forming portion 834 can decrease in the direction of movement of the water. That is, the thickness t5 of the flow path forming portion 834 can decrease farther from the valve communication hole 8382. In contrast, in order to easily mold the entire duct cover portion 830, the thickness t5 of the flow path forming portion 834 can be constant.

[0449] On the other hand, the flow path forming portion 834 can include a first flow path forming portion 834a forming an inner circumferential surface of the first cleaning flow path 833a, a second flow path forming portion 834b forming an inner circumferential surface of the second cleaning flow path 833b, and a third flow path forming portion 834c forming an inner circumferential surface of the third cleaning flow path 833c.

[0450] The end of the first flow path forming portion 834a and the end of the third flow path forming portion 834c can be configured to contact each other, and the end of the first flow path forming portion 834a and the end of the second flow path forming portion 834b can be configured to contact each other.

[0451] Further, the cleaning flow path portion 833 can include a flow path dividing rib 836 configured to divide the first cleaning flow path 833a, the second cleaning flow path 833b, and the third cleaning flow path 833c.

[0452] The flow path dividing rib 836 can extend from the end of the first flow path forming portion 834a and the end of the third flow path forming portion 834c toward the cover penetration hole 8313. That is, the flow path dividing rib 836 can extend from a portion where the end of the first flow path forming portion 834a and the end of the third flow path forming portion 834c contact each other toward the cover penetration hole 8313.

[0453] Thus, water discharged from the second discharge flow path 8332b can be uniformly discharged to the cover penetration hole 8313 along the flow path division rib 836. The flow path division rib 836 can be disposed on the top surface of the flow path discharge rib 835 by extending from the flow path formation portion 834 toward the flow path discharge rib 835.

[0454] In addition, the cleaning flow path portion 833 can include a communication flow path 8333 that communicates the discharge flow path 8332 and the cover penetration hole 8313.

[0455] The communication flow path 8333 can be disposed at the upper end of the cover penetration hole 8313 and can be disposed to face the cover penetration hole 8313. The communication flow path 8333 can be disposed to move water discharged from the discharge flow path 8332 to the cover penetration hole 8313.

[0456] In addition, the flow path formation portion 834 can be disposed to form the inner circumferential surface of the communication flow path 8333, and thus, it is possible to prevent water discharged from the discharge flow path 8332 from flowing outside the cover penetration hole 8313.

[0457] On the other hand, the cleaning flow path portion 833 can include a flow path support portion 837 that supports the flow path formation portion 834.

[0458] The flow path support portion 837 can be disposed to extend from the outer circumferential surface of the flow path formation portion 834 to the outside. The flow path support portion 837 can be disposed to protrude from the top surface of the cover main body 8311 and can support the flow path formation portion 834 in combination with the outer circumferential surface of the flow path formation portion 834. The flow path support portion 837 can be provided with a plurality of flow path support portions 837 along the circumference of the outer circumferential surface of the flow path formation portion 834.

[0459] Thus, the flow path formation portion 834 can withstand the water pressure of water inside and can improve the durability and reliability of the flow path formation portion 834 by being supported by the flow path support portion 837.

[0460] Figure 17 FIG. 10 is a perspective view illustrating the bottom surface of the duct cover portion of the laundry treating apparatus 1 according to an embodiment of the disclosure.

[0461] The duct cover portion 830 can include first and second heat dissipation ribs 8315a and 8315b that block heat transfer of heat from the first heat exchanger 910 to the cleaning flow path portion 833.

[0462] The first heat dissipation rib 8315a can protrude from the bottom surface of the cover main body 8311 to extend in a direction away from the cover penetration hole 8313. The second heat dissipation rib 8315b can protrude from the bottom surface of the cover main body 8311 to extend in parallel with the cover penetration hole 8313.

[0463] The first heat dissipation rib 8315a and the second heat dissipation rib 8315b can be provided in plural, and the second heat dissipation rib 8315b can be configured to be perpendicular to the first heat dissipation rib 8315a and to connect plural first heat dissipation ribs 8315a.

[0464] The first heat dissipation rib 8315a and the second heat dissipation rib 8315b can be configured to face the first heat exchanger 910, and heat transfer from the first heat exchanger 910 to the purge flow path portion 833 can be reduced by the first heat dissipation rib 8315a and the second heat dissipation rib 8315b.

[0465] In addition, the cover main body 8311 can include an evaporator cover main body 83111 facing the first heat exchanger 910, and a condenser cover main body 83112 extending rearward from the evaporator cover main body 83111 and facing the second heat exchanger 920. The first heat dissipation rib 8315a and the second heat dissipation rib 8315b can be provided on the bottom surface of the evaporator cover main body 83111, and the cover penetration hole 8313 can penetrate the evaporator cover main body 83111.

[0466] On the other hand, the duct cover portion 830 can include a flow path introduction groove 8349 recessed from the bottom surface to form the flow path formation portion 834. The flow path introduction groove 8349 can be configured to be recessed from the bottom surface of the cover main body 8311 to extend toward the flow path formation portion 834.

[0467] The flow path introduction groove 8349 can extend in the extension direction of the flow path formation portion 834. The flow path introduction groove 8349 can be generated in the process of injection molding the flow path formation portion 834, and thus the structural rigidity of the flow path formation portion 834 can be strengthened since the load received by the flow path formation portion 834 can be dispersed.

[0468] On the other hand, the duct cover portion 830 can include a duct cover extension portion 832 extending in the thickness direction from the outer surfaces of the cover main body 8311 and the communication cover main body 8312 along the periphery of the cover main body 8311 and the communication cover main body 8312. Figure 13 The duct 822 and the inflow duct 821 shown can be combined with the duct cover extension portion 832.

[0469] The pipe cover extension 832 protrudes in at least one of the thickness direction of the cover main body 8311 and the communication cover main body 8312, thereby not only improving the durability of the cover main body 8311 and the communication cover main body 8312, but also providing a space for installing an additional structure on the upper portion of the cover main body 8311 and the communication cover main body 8312.

[0470] On the other hand, the pipe cover extension 832 can include a cover insertion portion 8322 extending in the thickness direction of the pipe cover extension 832 to be inserted into the inner surfaces of the inflow pipe and the moving pipe 822, and a cover step portion 8223 spaced outward from the outer circumferential surface of the cover insertion portion 8322 and extending in the thickness direction Z2 to be combined with the outer surfaces of the moving pipe 822 and the inflow pipe 821.

[0471] A sealing seating portion 8324 can be provided between the inner circumferential surface of the cover step portion 8223 and the outer circumferential surface of the cover insertion portion 8322, and the upper ends of the moving pipe 822 and the inflow pipe 821 can be inserted into the sealing seating portion 8324. The moving pipe 822 and the inflow pipe 821 of the circulation flow path portion 820 can be combined between the cover step portion 8223 and the cover insertion portion 8322 by being inserted into the sealing seating portion 8324. Thus, the moving pipe 822 and the inflow pipe 821 can be combined with the cover main body 8311 and the communication cover main body 8312, respectively, so that the open top surfaces of the moving pipe 822 and the inflow pipe 821 are shielded.

[0472] Figure 18 FIG. 1 is an exploded perspective view of a flow path switching valve of a laundry treating apparatus according to an embodiment of the present application.

[0473] Figure 18 A detailed structure of a flow path switching valve 870 for selectively supplying water to a plurality of washing flow path portions 833 is described below. Figure 18 FIG. 1 is an exploded perspective view of a flow path switching valve of a laundry treating apparatus according to an embodiment of the present application.

[0474] The flow path switching valve 870 can include a supply switching portion 871 communicating with the pump 861 to receive the water from the pump 861, a switching connection portion 879 communicating with the supply switching portion 871 and connected to the valve connection portion 838 to deliver the water to the washing flow path portions 833, and a delivery portion 872 disposed between the supply switching portion 871 and the switching connection portion 879 to be combined with the supply switching portion 871 and the switching connection portion 879.

[0475] On the other hand, the connection passage 879 can include a connection delivery flow path 8792 that communicates with the delivery portion 872 and receives water from the delivery portion 872. The connection delivery flow path 8792 can communicate with the water storage tank 120 to become a passage that moves water received from the delivery portion 872 to the water storage tank 120.

[0476] Thereby, the water storage tank 120 receives water moved from the pump 861 to the flow path switching valve 870 through the flow path switching valve 870 through the connection delivery flow path 8792 and temporarily stores the water.

[0477] In this case, one end of the connection delivery flow path 8792 can be configured to face the delivery portion, and the other end can be configured to face the water storage tank 120.

[0478] In addition, one end and the other end of the connection delivery flow path 8792 can be spaced apart to prevent the one end and the other end of the connection delivery flow path 8792 from facing each other. The connection delivery flow path 8792 can be configured such that the one end and the other end thereof do not face each other in a straight line.

[0479] On the other hand, the supply switching portion 871 can include a rotating disc accommodation portion 8712 that is combined with the delivery portion 872, and a switching inflow portion 8711 that extends from the rotating disc accommodation portion 8712 toward the water collecting portion 860 and is connected to the first water collecting and discharging pipe 8911a (see FIG. 19). Figure 14

[0480] The switching inflow portion 8711 can communicate with the inside of the rotating disc accommodation portion 8712, thereby receiving water from the first water collecting and discharging pipe 8911a and moving the water to the inside of the rotating disc accommodation portion 8712.

[0481] In addition, the supply switching portion 871 can include a driving portion mounting portion 8713 that extends from the rotating disc accommodation portion 8712 away from the delivery portion 872, a valve driving portion 873 that is provided to the driving portion mounting portion 8713 and provides a rotating power, and a valve rotating portion 874 that is disposed inside the rotating disc accommodation portion 8712 and is configured to rotate in combination with the valve driving portion 873. The supply switching portion 871 can include a driving portion fixing member 8716 that fixes the valve driving portion 873 to the driving portion mounting portion 8713.

[0482] In addition, the supply switching portion 871 can include a switching rotating disc 875 that is accommodated in the rotating disc accommodation portion 8712 and is configured to rotate in combination with the valve rotating portion 874.

[0483] ​The valve rotating part 874 can include a second valve rotating shaft 8742 which rotates in conjunction with the valve driving part 873, and a first valve rotating shaft 8741 which rotates in conjunction with the second valve rotating shaft 8742 and the conversion rotating disc 875.

[0484] On the other hand, the transmission part 872 can include a transmission main body 8721 which is combined with the rotating disc accommodating part 8712, and a transmission contact part 8726 which extends from the transmission main body 8721 toward the conversion connecting part 879 and is combined with the conversion connecting part 879.

[0485] In addition, the transmission part 872 can include a transmission supply flow path 8722 which penetrates the transmission main body 8721 and the transmission contact part 8726 and communicates with the connection transmission flow path 8792 and the connection supply flow paths 8791a, 8791b, 8791c.

[0486] The transmission supply flow path 8722 can be provided in plural along the circumference of the transmission contact part 8726, and respectively communicate with the plural connection supply flow paths 8791a, 8791b, 8791c and the connection transmission flow path 8792.

[0487] The conversion rotating disc 875 can include a conversion rotating disc 8751 which is accommodated in the rotating disc accommodating part 8712 and rotates, a rotating disc communication hole 8752 which penetrates the conversion rotating disc 8751 and selectively communicates with the plural transmission supply flow paths 8722, and a rotating disc combination hole 8753 which penetrates the conversion rotating disc 8751 and is combined with the first valve rotating shaft 8741.

[0488] The conversion rotating disc 8751 can rotate in contact with one end of the transmission supply flow path 8722, and the rotating disc communication hole 8752 can be configured to selectively communicate with any one of the transmission supply flow paths 8722 according to the rotation of the conversion rotating disc 8751.

[0489] Accordingly, water flowing into the conversion inflow part 8711 according to the rotation of the conversion rotating disc 8751 can be selectively guided to the connection transmission flow path 8792 and the connection supply flow paths 8791a, 8791b, 8791c.

[0490] If water is supplied to the connection transmission flow path 8792, water stored in the water collecting part 860 can move toward the water storage tank 120. In addition, if water is supplied to any one of the connection supply flow paths 8791a, 8791b, 8791c, water can be supplied to any one of the washing flow path parts 833.

[0491] Accordingly, water can be selectively supplied to any one of the water storage tank 120 or the washing flow path portion 833 according to the operation of the flow path switching valve 870. In addition, if water is supplied to any one of the plurality of washing flow path portions 833, the pressure of water discharged to the first heat exchanger 910 can be higher than the pressure of water when water is continuously supplied to all of the plurality of washing flow path portions 833.

[0492] On the other hand, if water supplied to the flow path switching valve 870 flows out between the switching connection portion 879 and the nozzle cover portion 840, various devices required for the operation of the laundry treating apparatus can be in contact with water.

[0493] To prevent such a situation, the connection supply flow path 8791a, 8791b, 8791c can be formed integrally with the valve connection portion 838. Accordingly, water can be prevented from flowing out between the switching connection portion 879 and the valve connection portion 838.

[0494] The connection supply flow path 8791a, 8791b, 8791c can communicate with the washing flow path portion 833 by penetrating the bottom surface of the valve connection portion 838. The connection supply flow path 8791a, 8791b, 8791c can extend downward from the valve connection portion 838 at one time and extend in a direction away from the valve connection portion 838 at a second time.

[0495] The connection supply flow path 8791a, 8791b, 8791c can be configured to be lower than the top surface of the valve connection portion 838. The connection supply flow path 8791a, 8791b, 8791c can penetrate the valve connection portion 838, and one end thereof can be inserted into the inside of the washing flow path portion 833.

[0496] On the other hand, the switching connection portion 879 can include a switching extension portion 8793 expanded from the outer circumferential surface of the connection transfer flow path 8792 and the outer circumferential surface of the connection supply flow path 8791a, 8791b, 8791c.

[0497] The switching extension portion 8973 can be combined with the connection transfer flow path 8792 and the connection supply flow path 8791a, 8791b, 8791c. The switching extension portion 8793 can be formed integrally with the connection transfer flow path 8792 and the connection supply flow path 8791a, 8791b, 8791c, and can perform the role of fixing the connection transfer flow path 8792 and the connection supply flow path 8791a, 8791b, 8791c.

[0498] On the other hand, the transmission part 872 can include a transmission fastening part 8725 extending from the outer circumferential surface of the transmission contact part 8726 and combined with the conversion extension part 8793. The conversion connection part 879 can include the conversion fixing part 8794 extending from the conversion extension part 8793 to the transmission fastening part 8725 and combined with the transmission fastening part 8725.

[0499] The conversion fixing part 8794 and the transmission fastening part 8725 can be configured to face each other, and one end of the transmission fastening part 8725 can be received and combined with the conversion fixing part 8794. As illustrated, the conversion fixing part 8794 can be configured on one side and the other side of the conversion extension part 8793, and the transmission fastening part 8725 can be configured on one side and the other side of the transmission contact part 8726 to face the conversion fixing part 8794.

[0500] In addition, the conversion connection part 879 can include a connection protrusion 8795 protruding from the outer circumferential surface of the conversion extension part 8793 and configured to be spaced apart from the conversion fixing part 8794. In addition, the transmission part 872 can include a transmission installation hook 8724 extending from the outer circumferential surface of the transmission contact part 8726, and the connection protrusion 8795 is inserted into the transmission installation hook 8724.

[0501] The transmission installation hook 8724 can be configured at a position corresponding to the connection protrusion 8795 and combined with the connection protrusion 8795. As an example, as illustrated, the connection protrusion 8795 can be respectively protruded on one side and the other side in the height direction (Z direction) of the conversion extension part 8793, and the transmission installation hook 8724 can be respectively configured on one side and the other side in the height direction (Z direction) of the transmission contact part 8726.

[0502] Thus, the transmission part 872 can be combined with the conversion extension part 8793 through the connection protrusion 8795 and the conversion fixing part 8794, and can prevent the transmission part 872 from being spaced apart from the conversion extension part 8793.

[0503] In addition, the transmission part 872 can include a transmission protrusion part 8727 protruding from the center of the transmission contact part 8726 toward the conversion extension part 8793 and inserted into the conversion extension part 8793. The transmission protrusion part 8727 can prevent the transmission part 872 from escaping from the conversion connection part 879 by being inserted into the conversion extension part 8793.

[0504] On the other hand, the transfer portion 872 can include a transfer main body fixing member 8723 fixing the rotation disc accommodation portion 8712 to the transfer main body 8721, and the rotation disc accommodation portion 8712 can include a supply conversion fixing groove 8715 into which the transfer main body fixing member 8723 is inserted. In addition, the supply conversion portion 871 can be provided with a supply conversion hook 8717 protruding from an outer circumferential surface of the rotation disc accommodation portion 8712 to be coupled to the transfer main body 8721.

[0505] On the other hand, the flow path conversion valve 870 can include a connection sealing member 8773 disposed between the conversion connection portion 879 and the transfer portion 872. The connection sealing member 8773 is disposed between the conversion extension portion 8793 and the transfer contact portion 8726, and can prevent water from flowing out between the connection supply flow paths 8791a, 8791b, 8791c and the transfer supply flow path 8722.

[0506] The connection sealing member 8773 can be disposed to be accommodated in any one of the transfer contact portion 8726 or the conversion extension portion 8793. The connection sealing member 8773 can be disposed to surround the connection supply flow paths 8791a, 8791b, 8791c.

[0507] The conversion sealing portion 877 can include a shaft sealing member 8772 disposed between the second valve rotation shaft 8742 and the first valve rotation shaft 8741 to prevent water from flowing out to the valve driving portion 873, and a rotation disc sealing member 8771 surrounding an outer circumferential surface of the conversion rotation disc 8751 to prevent water from flowing out between the rotation disc accommodation portion 8712 and the transfer main body 8721.

[0508] Between the conversion rotation disc 875 and the first valve rotation shaft 8741 can include a flow path conversion elastic member 876 applying pressure to the conversion rotation disc 875 in a direction away from the first valve rotation shaft 8741.

[0509] Figure 19 FIG. 1 is a perspective view showing a pipe cover portion to which a nozzle cover portion is coupled in a laundry treating apparatus according to an embodiment of the present application.

[0510] The circulation flow path portion 820 can further include a nozzle cover portion 840 preventing water flowing in the cleaning flow path portion 833 from being scattered outside by shielding the cleaning flow path portion 833.

[0511] The nozzle cover portion 840 can be coupled with the upper end of the washing flow path portion 833. When the shield cover body 8311 is viewed from the upper side of the nozzle cover portion 840, the nozzle cover portion 840 can accommodate the washing flow path portion 833 and be coupled with the upper end of the washing flow path portion 833, whereby the washing flow path portion 833 can be shielded by the nozzle cover portion 840.

[0512] The nozzle cover portion 840 can extend in the extension direction of the washing flow path portion 833. That is, the nozzle cover portion 840 can extend from one side where the flow path switching valve 870 is disposed to the other side where the inflow communication hole 8314 is disposed. As an example, the one side can be the direction in which the flow path switching valve 870 extends from the valve connection portion 838, and the other side can be the front (X direction) where the inflow communication hole 8314 is disposed.

[0513] In addition, the length L4 of the nozzle cover portion 840 extending in the front-rear direction can be less than or equal to the length L2 of the shield cover body 8311 extending. The length L4 of the nozzle cover portion 840 extending in the front-rear direction can be greater than or equal to the length of the washing flow path portion 833 extending, which can be appropriately designed according to the amount of water required to wash the first heat exchanger 910.

[0514] The nozzle cover portion 840 can be configured to be coupled with Figure 15 the upper end of the flow path forming portion 834 to shield the washing flow path portion 833. As shown, the nozzle cover portion 840 can be configured to be coupled with and shield the first washing flow path 833a, the second washing flow path 833b, and the third washing flow path 833c.

[0515] Thereby, the nozzle cover portion 840 can prevent water flowing in the washing flow path portion 833 from being scattered to the outside.

[0516] Figure 20 FIG. 8 is a cross-sectional view illustrating an example of a nozzle cover portion of a laundry treatment apparatus according to an embodiment of the disclosure. Figure 20 FIG. 9 is a cross-sectional view illustrating an example of a nozzle cover portion of a laundry treatment apparatus according to an embodiment of the disclosure. Figure 19 FIG. 10 is a cross-sectional view illustrating the length direction (B-B' line) inside the duct cover portion 830 and the nozzle cover portion 840 shown in FIG. 9.

[0517] The nozzle cover portion 840 can include a nozzle cover body 841 that shields the washing flow path portion 833.

[0518] The nozzle cover body 841 can be coupled with Figure 15The upper end 8341 of the flow path forming portion 834 shown is joined to extend in the extension direction of the purge flow path portion 833. The nozzle cover body 841 can extend in parallel with the guide flow path 8331, and the distance between the nozzle cover body 841 and the purge flow path portion 833 can gradually increase in the direction of movement of the water.

[0519] That is, the distance between the bottom surface of the first discharge flow path 8332a and the bottom surface of the second discharge flow path 8332b and the nozzle cover body 841 can gradually increase in the direction of movement of the water.

[0520] In addition, the nozzle cover portion 840 can further include a nozzle shielding rib 843 that moves the water moving along the purge flow path portion 833 toward the cover through hole 8313.

[0521] The nozzle shielding rib 843 can extend from the end of the nozzle cover body 841 toward the shielding cover body 8311. The nozzle shielding rib 843 can perform the function of shielding the cover through hole 8313 together with the nozzle cover body 841, and can be provided at the end of the cover through hole 8313.

[0522] That is, one end of the cover through hole 8313 can be connected to the second discharge flow path 8332b, and the other end can be connected to the nozzle shielding rib 843. Unlike this, the nozzle shielding rib 843 can be spaced apart from the cover through hole 8313 and positioned further forward than the cover through hole 8313.

[0523] The nozzle shielding rib 843 can perform the function of temporarily storing the water discharged from the purge flow path portion 833 inside the purge flow path portion 833, and can cause the water moving along the purge flow path portion 833 to collide and guide the water to move toward the cover through hole 8313.

[0524] On the other hand, the condensed water discharged from the second discharge flow path 8332 can move along the flow path discharge rib 835 and be discharged through the cover through hole 8313. At this time, the condensed water can not be discharged toward the first heat exchanger 910 in the extension direction of the flow path discharge rib 835, but can be discharged toward a position further forward than the first heat exchanger 910. In particular, the faster the condensed water passes through the flow path discharge rib 835, the less the condensed water contacts the inflow surface of the first heat exchanger 910.

[0525] To this end, the nozzle cover portion 840 can further include a nozzle conversion rib 846 that guides the water passing through the flow path discharge rib 835 toward the first heat exchanger 910.

[0526] The nozzle conversion rib 846 can be configured to extend from the nozzle cover rib 843 toward the cover penetration hole 8313 to face the flow path discharge rib 835. The nozzle conversion rib 846 can extend toward the first heat exchanger 910, and the tip of the nozzle conversion rib 846 can be configured to protrude more toward the lower portion than the cover penetration hole 8313. The nozzle conversion rib 846 can extend obliquely from the flow path discharge rib 835, and the tip of the nozzle conversion rib 846 and the tip of the flow path discharge rib 835 can be configured to be spaced apart from each other.

[0527] The tip of the nozzle conversion rib 846 can be configured to be more forward than the front surface of the first heat exchanger 910, and the tip of the flow path discharge rib 835 can be configured to be more rearward than the front surface of the first heat exchanger 910. Thus, water passing through the flow path discharge rib 835 can collide with the nozzle conversion rib 846 and be discharged from between the tip of the nozzle conversion rib 846 and the tip of the flow path discharge rib 835.

[0528] On the other hand, the inclination angle θ1 of the first discharge flow path 8332a, i.e., the inclination angle θ1 of the first inclined surface 8316a, can be greater than or equal to the inclination angle θ2 of the second discharge flow path 8332b, i.e., the inclination angle θ2 of the second inclined surface 8316b.

[0529] Thus, water flowing into the cleaning flow path part 833 can move toward the cover penetration hole 8313 under the action of gravity during passage through the first discharge flow path 8332a and the second discharge flow path 8332b and be completely discharged. In addition, the thickness of the first inclined surface 8316a and the second inclined surface 8316b can be configured to be constant.

[0530] Figure 21 FIG. 9 is a cross-sectional view illustrating another embodiment of a nozzle cover part of a laundry treating apparatus according to an embodiment of the disclosure. Hereinafter, the nozzle cover part 840 according to the embodiment of the disclosure will be described with reference to FIG. 9. Figure 20 The nozzle cover part 840 according to the embodiment of the disclosure will be described with reference to FIG. 9.

[0531] The nozzle cover part 840 can further include a nozzle introduction part 849 that reduces the distance between the cleaning flow path part 833 and the nozzle cover body 841.

[0532] The nozzle introduction part 849 can be configured to protrude from the nozzle cover body 841 toward the inside of the cleaning flow path part 833. The nozzle introduction part 849 can be configured to protrude from the top surface of the nozzle cover body 841 toward the first discharge flow path 8332a and the second discharge flow path 8332b.

[0533] The nozzle introduction portion 849 can be configured to gradually increase in length protruding from the nozzle cover body 841 in the direction of movement of the condensed water.

[0534] The nozzle introduction portion 849 can be configured to form an inclined angle corresponding to the inclined surface 8316 toward one surface of the washing flow path portion 833.

[0535] For example, an inclined angle θ4 of one surface of the nozzle introduction portion 849 facing the first inclined surface 8316a can correspond to the inclined angle θ1 of the first inclined surface, and an inclined angle θ3 of one surface of the nozzle introduction portion 849 facing the second inclined surface 8316b can correspond to the inclined angle θ2 of the second inclined surface.

[0536] A distance between one surface of the nozzle introduction portion 849 facing the first discharge flow path 8332a and the first inclined surface 8316a can correspond to a height between a bottom surface and a top surface of the guide flow path 8331.

[0537] In addition, a distance between one surface of the nozzle introduction portion 849 facing the second inclined surface 8316b and the second inclined surface 8316b can correspond to a height between a bottom surface and a top surface of the guide flow path 8331.

[0538] The nozzle introduction portion 849 can perform a function of narrowing an inner space of the washing flow path portion 833, and thus a height of the washing flow path portion 833 can be reduced, and a flow rate of water reaching the nozzle shielding rib 843 can be increased to move rapidly toward the cover penetration hole 8313.

[0539] In addition, the washing flow path portion 833 can be configured to have a constant height by forming the nozzle introduction portion 849. Thus, when water moves in the washing flow path portion 833, a volume occupied by air inside the washing flow path portion 833 can be reduced. In addition, noise and vibration generated by the water inside the washing flow path portion 833 colliding with an inner circumferential surface of the washing flow path portion 833 can be reduced.

[0540] In addition, even if water first reaches a specific area of the nozzle introduction portion 849, the water can be uniformly discharged along the entire area of the nozzle introduction portion 849 and through the cover penetration hole 8313.

[0541] Figure 22 FIG. 7 is a cross-sectional view illustrating another example of a nozzle cover portion of a laundry treating apparatus according to an embodiment of the present application. Figure 22is a sectional view (B-B') of the inside of the duct cover part 830 and the nozzle cover part 840.

[0542] The nozzle cover body 841 can include a nozzle fusion plate 8411 combined with the flow path forming part 834 to shield the guide flow path 8331, a first nozzle inclined plate 8412 extending from the nozzle fusion plate 8411 to be combined with the flow path forming part 834 to shield the first discharge flow path 8332a, and a second nozzle inclined plate 8413 extending from the first nozzle inclined plate 8412 to be combined with the flow path forming part 834 to shield the second discharge flow path.

[0543] The nozzle shielding rib 843 can extend downward from the end of the second nozzle inclined plate 8413 to be combined with the top surface of the duct cover body 831. The nozzle conversion rib 846 can extend from the second nozzle inclined plate 8413 or the nozzle shielding rib 843 toward the cover penetration hole 8313.

[0544] The first nozzle inclined plate 8412 can be configured to be inclined from the nozzle fusion plate 8411 in the direction of movement of water, and the second nozzle inclined plate 8413 can be configured to be inclined from the first nozzle inclined plate 8412 in the direction of movement of water.

[0545] The inclination angle θ3 of the first nozzle inclined plate with respect to the nozzle fusion plate can correspond to the inclination angle θ1 of the first inclined surface, and the inclination angle θ4 of the second nozzle inclined plate with respect to the nozzle fusion plate 8411 can correspond to the inclination angle θ2 of the second inclined surface. Thereby, the inside height of the cleaning flow path part 833 can be constantly extended.

[0546] The thicknesses of the nozzle fusion plate 8411, the first nozzle inclined plate 8412, and the second nozzle inclined plate 8413 can be constant, which has the effect of reducing the manufacturing cost of the nozzle cover part 840.

[0547] Figure 23 is Figure 22 a side view and a bottom view of the nozzle cover part. Figure 23 (a) of FIG. 1 is a view of the nozzle cover part 840 viewed from the side, Figure 23 (b) of FIG. 1 is a bottom view of the nozzle cover part 840.

[0548] The nozzle conversion rib 846 can extend from the second nozzle inclined plate 8413 or the nozzle shielding rib 843 toward the cover penetration hole 8313. An angle θ5 between the nozzle conversion rib 846 and the nozzle shielding rib 843 can be formed to be 10 degrees or more and 80 degrees or less, and the angle θ5 between the nozzle conversion rib 846 and the nozzle shielding rib 843 can be variously designed according to an arrangement relationship of the nozzle shielding rib 843 and the first heat exchanger 910 or an arrangement relationship of the nozzle shielding rib 843 and the cover penetration hole 8313.

[0549] A height H7 of the nozzle shielding rib 843 can be less than a height of the second inclined surface 8316b, and a height H6 of the second nozzle inclined plate 8413 can be less than a height of the first inclined surface 8316a and greater than the height of the second inclined surface 8316b.

[0550] Accordingly, the flow path forming portion 834 can be protruded at a predetermined height to be combined with the nozzle cover portion 840, the nozzle cover portion 840 can face the first inclined surface 8316a and the second inclined surface 8316b, and the washing flow path portion 833 can be formed at a predetermined height.

[0551] On the other hand, the nozzle cover portion 840 can include a nozzle division rib 848 that divides water discharged from a plurality of the washing flow path portions 833 together with the flow path division rib 836.

[0552] The nozzle division rib 848 can extend from the nozzle conversion rib 846 toward the flow path division rib 836. The nozzle division rib 848 can be configured to overlap the flow path division rib 836, and as an example, the nozzle division rib 848 can be configured to be combined with the flow path division rib 836.

[0553] The nozzle division rib 848 can divide water discharged from a plurality of the washing flow path portions 833 together with the flow path division rib 836, and accordingly, the nozzle division rib 848 can guide water to be uniformly sprayed toward the first heat exchanger 910 by preventing water discharged from any one of the washing flow path portions 833 from moving toward the other washing flow path portions 833.

[0554] As shown in (b) of FIG. 8, Figure 23 The nozzle cover portion 840 can include a nozzle combination portion 844 combined with the flow path forming portion 834, as shown in (b) of FIG. 8.

[0555] The nozzle combination portion 844 can be configured to extend from the nozzle cover body 841 toward the flow path forming portion 834, and can be configured to be combined with an upper end of the flow path forming portion 834.

[0556] The nozzle coupling portion 844 can be formed in one body with the flow path forming portion 834 by being fused to the upper end of the flow path forming portion 834, and the nozzle fusion plate 8411 can be configured to be in contact with the upper end of the flow path forming portion 834. The nozzle coupling portion 844 can face the flow path forming portion 834 and extend in the extension direction of the flow path forming portion 834.

[0557] In addition, the nozzle cover portion 840 can include a nozzle extension rib 842 to prevent the nozzle cover body 841 from being detached from the washing flow path portion 833.

[0558] The nozzle extension rib 842 can be configured to accommodate the flow path forming portion 834 by extending in the thickness direction from the outer circumferential surface of the nozzle cover body 841. The nozzle extension rib 842 can be configured to have a width greater than the width of the flow path forming portion 834 to accommodate the outer circumferential surface of the flow path forming portion 834.

[0559] Differently, in the case where the flow path support portion 837 is provided at the outer circumferential surface of the flow path forming portion 834, the nozzle extension rib 842 can be configured to accommodate the upper end of the flow path support portion 837.

[0560] On the other hand, the distance t1 between the inner circumferential surfaces of the nozzle coupling portion 844 extending from the nozzle fusion plate 8411 can correspond to the width t1 of the guide flow path 8331.

[0561] The distance t2 between the inner circumferential surfaces of the nozzle coupling portion 844 extending from the first nozzle inclined plate 8412 can correspond to the width t2 of the first discharge flow path 8332a, and the distance t3 between the inner circumferential surfaces of the nozzle coupling portion 844 extending from the second nozzle inclined plate 8413 can correspond to the width t3 of the second discharge flow path 8332b.

[0562] Thus, the nozzle fusion plate 8411 can prevent water inside the washing flow path portion 833 from flowing outside by shielding the washing flow path portion 833.

[0563] Figure 24 FIG. 8 is a cross-sectional view illustrating an example of a nozzle cover portion and a flow path forming portion combined in a laundry treatment apparatus according to an embodiment of the disclosure.

[0564] The flow path support portion 837 can include a flow path support bent portion 8371 to facilitate coupling of the nozzle extension rib 842.

[0565] The flow path support bent portion 8371 can be configured to be spaced apart from at least a portion of the nozzle extension rib 842. The flow path support bent portion 8371 can be formed at the end coupled with the nozzle extension rib 842.

[0566] The nozzle extension rib 842 can be configured to extend in a thickness direction from an outer circumferential surface of the nozzle cover body 841, and can support the bent portion 8371 in combination with the flow path support portion 837 along the flow path. Thereby, burrs can be prevented from being generated in a process in which the lower end portion 8422 of the nozzle extension rib 842 is combined with the flow path support portion 837.

[0567] In addition, a height H7 by which the flow path forming portion 834 protrudes from a top surface of the duct cover body 831 can be greater than or equal to a height H8 by which the flow path support portion 837 protrudes, and thereby the nozzle cover body 841 can be configured to be spaced apart from the flow path support portion 837.

[0568] On the other hand, a thickness t5 of the flow path forming portion 834 can be less than or equal to a width t1 of the purge flow path portion 833, and a height of the purge flow path portion 833 can correspond to the height H7 of the flow path forming portion 834.

[0569] In addition, the nozzle cover body 841 can be combined with an upper end portion 8341 of the flow path forming portion 834, and the flow path forming portion 834 can be combined in one body with the nozzle cover body 841 through a heat fusion process, for example, can be combined with the nozzle cover body 841 through a fusion method.

[0570] Here, the heat fusion process can mean a process of combining two thermoplastic members with each other by applying heat and pressure to surfaces of the two thermoplastic members. In other words, it can mean a method of applying heat to the nozzle combining portion 844 to make the nozzle combining portion 844 come into contact with the flow path forming portion 834, and combining the nozzle combining portion 844 in one body with the flow path forming portion 834.

[0571] In addition, the flow path forming portion 834 can be combined with the nozzle cover body 841 through a vibration fusion process.

[0572] Here, the vibration fusion process is a process of combining two thermoplastic members with each other after melting the two thermoplastic members using frictional heat generated at a contact portion by up-and-down or left-and-right vibration by pressing the two thermoplastic members with each other.

[0573] In other words, the vibration fusion process can mean a process of vibrating the nozzle cover body 841 or the flow path forming portion 834, and combining the nozzle combining portion 844 and the flow path forming portion 834 by frictional heat generated between the nozzle combining portion 844 and the flow path forming portion 834.

[0574] Thus, the nozzle cover body 841 can more effectively shield the purge flow path part 833 than when combined with the flow path forming part 834 using a hook or a bolt-nut method, and since the time for modification and repair is lengthened, it is possible to extend the life of the entire product.

[0575] In addition, the nozzle cover body 841 is integrated with the flow path forming part 834, thereby making it possible to reduce material costs and to simplify the assembly process.

[0576] In addition, even if an additional purge flow path tube is not configured, the purge flow path part 833 can be formed by the combination of the nozzle cover part 840 and the duct cover part 830, thereby having the advantage of a simple manufacturing process.

[0577] Figure 25 FIG. 7 is a cross-sectional view showing another embodiment of the combination of the nozzle cover part and the flow path forming part in a laundry treating apparatus according to an embodiment of the present application.

[0578] Figure 24 FIG. 7 is a cross-sectional view showing another embodiment of the combination of the nozzle cover part and the flow path forming part in a laundry treating apparatus according to an embodiment of the present application. Figure 25 FIG. 7 is a cross-sectional view showing another embodiment of the combination of the nozzle cover part and the flow path forming part in a laundry treating apparatus according to an embodiment of the present application.

[0579] The flow path forming part 834 can further include a first coupling rib 8342 forming an inner side surface of the purge flow path part 833, and a second coupling rib 8343 forming an outer side surface of the purge flow path part 833.

[0580] The first coupling rib 8342 can be protruded from the flow path forming part 834 to be coupled with the nozzle cover body 841, and the second coupling rib 8343 can be protruded from the flow path forming part 834 to be spaced apart from the first coupling rib 8342 and coupled with the nozzle coupling part 844. The height H11 of the second coupling rib 8343 protruded from the flow path forming part 834 can correspond to the first coupling rib 8342.

[0581] On the other hand, the lower end of the nozzle coupling part 844 can be in contact with the upper end of the second coupling rib 8343, and the nozzle fusion plate 8411 and the first coupling rib 8342 can be configured to be in contact with each other.

[0582] The second coupling rib 8343 can be coupled with the nozzle coupling portion 844 through a heat fusion process, and can be coupled through a vibration fusion process. In this process, the nozzle coupling portion 844 can be fused to be coupled with the second coupling rib 8343. On the other hand, the flow path forming portion 834 can further include a flow path sealing groove 8344 disposed between the first coupling rib 8342 and the second coupling rib 8343, extending in the extension direction of the purge flow path portion 833, and a flow path sealing member 8345 seated in the flow path sealing groove 8344, shielding between the nozzle cover body 841 and the purge flow path portion 833.

[0583] The heights H11 to which the second coupling rib 8343 and the first coupling rib 8342 protrude can correspond to the diameter of the flow path sealing member 8345.

[0584] The flow path sealing member 8345 is configured to be in contact with the nozzle cover body 841, shield between the nozzle cover body 841 and the flow path sealing groove 8344, and prevent water inside the purge flow path portion 833 from flowing out through the nozzle cover body 841. That is, by the flow path sealing member 8345, it is possible to prevent water from flowing out from the inside of the purge flow path portion 833 to the outside.

[0585] In addition, the flow path sealing groove 8344 and the flow path sealing member 8345 can be provided in plural between the flow path forming portion 834, and can be configured to overlap in the width direction.

[0586] If the flow path sealing groove 8344 and the flow path sealing member 8345 are provided in plural, the shielding force of the nozzle cover body 841 can be increased compared to when the flow path sealing groove 8344 and the flow path sealing member 8345 are provided in a single.

[0587] The distance t6 between the inner circumferential surfaces of the flow path introduction grooves 8349 can be smaller than the thickness t5 of the flow path forming portion 834, and the flow path introduction grooves 8349 can be accommodated in the flow path forming portion 834.

[0588] Figure 26 It is a perspective view of the duct cover portion 830 and the duct sealing portion 880 of the laundry treating apparatus 1 according to an embodiment of the present invention.

[0589] The circulation flow path portion 820 can be configured in a duct shape disposed outside the drum 200. The circulation flow path portion 820 can include a supply duct 828 communicating with the duct communication hole 417, supplying air to the drum 200, accommodating the first heat exchanger 910 and the second heat exchanger 920, and a discharge duct 823 discharging air passing through the supply duct 828.

[0590] The supply duct 828 can include the inflow duct 821 and the moving duct 822 described above. The supply duct 828 can receive air from the drum 200 through the inflow communication hole 8314, and the exhaust duct 823 can be provided at the end of the supply duct 828 to guide the air to the drum 200.

[0591] On the other hand, air exhausted from the drum 200, which flows into the supply duct 828, can contain a large amount of moisture discharged from laundry. That is, air flowing into the supply duct 828 can maintain a high temperature or a high humidity state until it is supplied again to the drum through the exhaust duct 823.

[0592] At this time, since various devices that control the operation of the laundry treating apparatus 1 are provided outside the circulation flow path part 820, air exhausted from the drum 200 is not preferably exhausted outside the circulation flow path part 820.

[0593] To this end, the circulation flow path part 820 can include a duct sealing part 880 configured to prevent air inside the supply duct 828 from being exhausted through the duct cover part 830.

[0594] The duct sealing part 880 can be configured to be disposed between the supply duct 828 and the duct cover part 830 to prevent air inside the supply duct 828 from being exhausted through the duct cover part 830. The duct sealing part 880 can block the inside and the outside of the circulation flow path part 820 by shielding a space between the duct cover part 830 and the supply duct 828, which are in contact with each other.

[0595] Specifically, the duct sealing part 880 can include a first duct sealing part 880 configured to prevent air inside the moving duct 822 from being exhausted through the shielding cover body 8311, and a second duct sealing part 880 configured to prevent air inside the inflow duct 821 from being exhausted through the communication cover body 8312.

[0596] The first duct sealing part 880 can be disposed between the shielding cover body 8311 and the moving duct 822, and the second duct sealing part 880 can be disposed between the communication cover body 8312 and the inflow duct 821.

[0597] In addition, the duct cover part 830 can be formed in one body to be seated on the open top surface of the inflow duct 821 and the moving duct 822. Thereby, the manufacturing cost of the duct cover part 830 can be reduced, and the duct cover part 830 can be easily combined with the supply duct 828.

[0598] At this time, the duct seal part 880 can be formed integrally along the circumference of the duct cover part 830, and specifically, the first duct seal part 880 and the second duct seal part 880 can be formed integrally to be disposed in the duct cover part 830.

[0599] The duct seal part 880 can be formed as a closed curve along a portion of the duct cover part 830 in contact with the supply duct 828.

[0600] The duct seal part 880 can be formed integrally in the shape of an O-ring, and can be formed in various shapes capable of shielding a space between the duct cover part 830 and the supply duct 828.

[0601] Figure 27 FIG. 10 is a perspective view illustrating a bottom surface of a duct cover part 830 of a laundry treating apparatus 1 according to an embodiment of the disclosure.

[0602] The duct cover part 830 can include a duct cover extension part 832 combined with the supply duct 828. The duct cover extension part 832 can be configured to be combined with the moving duct 822 and the inflow duct 821.

[0603] The duct cover extension part 832 can extend from the outer circumferential surfaces of the communication cover body 8312 and the shielding cover body 8311 in the thickness direction to be combined with the moving duct 822 and the inflow duct 821.

[0604] The duct cover extension part 832 can be configured to protrude in the thickness direction (Z direction) from at least one of the two side surfaces and the back surface of the shielding cover body 8311 or the communication cover body 8312.

[0605] The duct cover extension part 832 can not only improve the durability of the shielding cover body 8311 and the communication cover body 8312, but also allow the upper ends of the moving duct 822 and the inflow duct 821 to be inserted.

[0606] On the other hand, the duct cover extension part 832 can include a seal disposition part 8324 providing a space in which the duct seal part 880 is disposed.

[0607] The seal disposition part 8324 can be recessed from the lower end to the upper portion of the duct cover extension part 832 along the circumference of the duct cover extension part 832.

[0608] The sealing seating portion 8324 is provided at a lower end of the duct cover extension portion 832, and an upper end of the supply duct 828 can be inserted into the sealing seating portion 8324, which can be configured to accommodate the duct sealing portion 880. Thus, the duct sealing portion 880 can be accommodated in the sealing seating portion 8324 to be disposed between the upper end of the supply duct 828 and an inner circumferential surface of the sealing seating portion 8324.

[0609] The duct sealing portion 880 can have a diameter smaller than that of the sealing seating portion 8324 to be accommodated in the sealing seating portion 8324.

[0610] As an example, the sealing seating portion 8324 can include a first sealing seating portion 83241 into which an upper end of the moving duct 822 is inserted, and a second sealing seating portion 83242 into which an upper end of the inflow duct 821 is inserted.

[0611] The first sealing seating portion 83241 can be provided at the duct cover extension portion 832 extending from an outer circumferential surface of the cover main body 8311 and extend along a circumference of the moving duct 822. The first sealing seating portion 83241 can be provided at one surface of the duct cover extension portion 832 facing the upper end of the moving duct 822.

[0612] In addition, a distance between inner circumferential surfaces of the first sealing seating portion 83241 can be configured to have a length corresponding to the upper end of the moving duct 822, and thus the upper end of the moving duct 822 can be inserted into the first sealing seating portion 83241.

[0613] The first duct sealing portion 881 can be accommodated in the first sealing seating portion 83241 to be disposed between the inner circumferential surface of the first sealing seating portion 83241 and the upper end of the moving duct 822. Thus, the first duct sealing portion 881 can shield between the moving duct 822 and the first sealing seating portion 83241, and can prevent air inside the moving duct 822 from flowing out through the cover main body 8311.

[0614] The first duct sealing portion 880 can have a diameter corresponding to that of the moving duct 822, and can be disposed to face the upper end of the moving duct 822.

[0615] Further, the second seal seating portion 83242 can be disposed in a pipe cover extension portion 832 extending from an outer circumferential surface of the communication cover main body 8312 and extending along a periphery of the inflow pipe 821. The second seal seating portion 83242 can be provided on a side of the pipe cover extension portion 832 facing the inflow pipe 821.

[0616] The second seal seating portion 83242 can be configured to have a diameter greater than a diameter of the inflow communication hole 8314 so as to accommodate at least a portion of the inflow communication hole 8314.

[0617] A distance between inner circumferential surfaces of the second seal seating portion 83242 can be configured to have a length corresponding to an upper end of the inflow pipe 821, whereby the upper end of the inflow pipe 821 can be inserted into the second seal seating portion 83242.

[0618] The second pipe seal portion 882 can be accommodated in the first seal seating portion 83242 and disposed between the inner circumferential surfaces of the second seal seating portion 83242 and the upper end of the inflow pipe 821. Thereby, the second pipe seal portion 882 can shield between the inflow pipe 821 and the second seal seating portion 83242, and can prevent air inside the inflow pipe 821 from flowing out through the communication cover main body 8312.

[0619] A diameter of the second pipe seal portion 880 can correspond to a diameter of the inflow pipe 821, one end of the second pipe seal portion 880 can be parallel to the first pipe seal portion 880, and the other end of the second pipe seal portion 880 can be more protruded than the first pipe seal portion 880.

[0620] On the other hand, as described above, the first pipe seal portion 880 and the second pipe seal portion 880 can be formed as one body. To this end, the first seal seating portion 83241 can be configured to communicate with the second seal seating portion 83242.

[0621] An inner circumferential surface of the first seal seating portion 83241 can form a continuous side with an inner circumferential surface of the second seal seating portion 83242, and a diameter of the first seal seating portion 83241 can correspond to a diameter of the second seal seating portion 83242.

[0622] Thereby, the first pipe seal portion 880 and the second pipe seal portion 880 can be formed as one body and accommodated in the seal seating portion 8324, and not only can the pipe seal portion 880 be easily inserted into the seal seating portion 8324, but also air inside the circulation flow path portion 820 can be prevented from flowing out to the outside.

[0623] On the other hand, the duct cover extension 832 can include a cover insertion portion 8322 forming an inner side surface of the seal seating portion 8324, and a cover step portion 8223 forming an outer side surface of the seal seating portion 8324.

[0624] The seal seating portion 8324 can be disposed between the cover insertion portion 8322 and the cover step portion 8223, the cover insertion portion 8322 can be located at a position more inward than the seal seating portion 8324 to form an inner circumferential surface of the duct cover extension 832, and the cover step portion 8223 can be located at a position more outward than the seal seating portion 8324 to form an outer side surface of the duct cover extension 832.

[0625] The cover insertion portion 8322 can extend from the outer surfaces of the communication cover body 8312 and the shield cover body 8311 to be inserted into the interiors of the moving duct 822 and the inflow duct 821. The cover step portion 8223 can extend downward from the duct cover extension 832 and can extend along the outer side surfaces of the moving duct 822 and the inflow duct 821 to be in contact with the outer side surfaces of the moving duct 822 and the inflow duct 821.

[0626] Thus, the upper ends of the moving duct 822 and the inflow duct 821 can be configured to be accommodated in the seal seating portion 8324, the outer circumferential surfaces of which are in contact with the cover step portion 8223, and the inner circumferential surfaces of which are in contact with the cover coupling portion 8392.

[0627] Figure 28 is a sectional view illustrating a case in which a duct cover portion and a moving duct are coupled in a laundry treating apparatus according to an embodiment of the present disclosure. Specifically, Figure 27 is a view illustrating a section cut along the line A-A'.

[0628] The moving duct 822 and the inflow duct 821 can include a duct coupling portion 822a inserted into the seal seating portion 8324 to be coupled with the duct cover extension 832. The duct coupling portion 822a can correspond to the upper ends of the moving duct 822 and the inflow duct 821, and can be configured to be higher than the first heat exchanger 910 to be coupled with the duct cover extension 832.

[0629] The duct coupling portion 822a can be formed to have a thickness corresponding to the seal seating portion 8324, and the thickness of the duct coupling portion 822a can be configured to correspond to a distance between the inner circumferential surface of the seal seating portion 8324.

[0630] An outer circumferential surface of the pipe coupling portion 822a can be configured to be in contact with the cover step portion 8223, and an inner circumferential surface of the pipe coupling portion 822a can be configured to be in contact with the cover coupling portion 8392.

[0631] In addition, the pipe sealing portion 880 can be disposed at an upper end of the pipe coupling portion 822a and an inner circumferential surface of the sealing seating portion 8324. Thus, the pipe sealing portion 880 can prevent air inside the circulation flow path portion 820 from flowing out to the outside through the sealing seating portion 8324.

[0632] In addition, an outer circumferential surface of the pipe coupling portion 822a is in contact with the cover step portion 8223, an inner circumferential surface is in contact with the cover coupling portion 8392, and an upper end of the pipe coupling portion 822a is in contact with the pipe sealing portion 880, thereby preventing air inside the moving pipe and the inflow pipe 821 from flowing out between the pipe coupling portion 822a and the pipe cover extension portion 832.

[0633] On the other hand, the pipe cover extension portion 832 can include a cover mounting hook 8391 extending from an outer surface of the cover step portion 8223 and disposed along a circumferential edge of the cover step portion 8223. The cover mounting hook 8391 can be disposed in a plurality along an outer circumferential surface of the cover step portion 8223.

[0634] In addition, the moving pipe 822 and the inflow pipe 821 can include a pipe protrusion 824 protruding from an outer circumferential surface of the pipe coupling portion 822a, and the cover mounting hook 8391 is coupled to the pipe protrusion 824. The pipe protrusion 824 can be disposed in a plurality along an outer circumferential surface of the pipe coupling portion 822a.

[0635] Thus, a user can not only easily attach and detach the cover mounting hook 8391 to the pipe protrusion 824, but also easily couple the pipe cover portion 830 to the moving pipe and the inflow pipe.

[0636] In addition, the pipe coupling portion 822a can be inserted into the sealing seating portion 8324 and coupled to the cover step portion 8223 and the cover insertion portion 8322, and further coupled to the cover mounting hook 8391 using the pipe protrusion 824 protruding from an outer surface. Thus, the pipe cover portion 830 can be firmly coupled to the moving pipe 822 and the inflow pipe 821.

[0637] On the other hand, the moving pipe 822 can include a pipe support portion 822b supporting the cover insertion portion 8322 upward.

[0638] The duct support portion 822b can extend in a width direction on an inner circumferential surface of the moving duct 822, and can extend upward from a bottom surface of the moving duct 822 toward the cover insertion portion 8322 to support the cover insertion portion 8322 in an upper portion.

[0639] In addition, the cover insertion portion 8322 can include a cover fastening portion 8393 combined with the duct support portion 822b and fixing the cover insertion portion 8322 to the duct support portion 822b.

[0640] The cover fastening portion 8393 can extend in a direction away from the duct combination portion 822a, thereby being configured such that a bottom surface thereof faces the duct support portion 822b. The cover fastening portion 8393 can be configured to be combined with the duct support portion 822b, and as an example, can be combined with the duct support portion 822b using a bolt-nut method.

[0641] Thus, even if the duct cover portion 830 is disposed on an open top surface of the moving duct 822 and the inflow duct 821, the moving duct 822 can stably support the duct cover portion 830 using the duct support portion 822b and the cover fastening portion 8393.

[0642] On the other hand, the moving duct 822 can include duct ribs 829a, 829b releasing heat to outside air.

[0643] The duct ribs 829a, 829b can protrude from an outer surface of the moving duct 822, and be configured to be more forward than the first heat exchanger 910. Thus, an area in which the moving duct 822 contacts outside air increases, so that air discharged from the drum can be quickly cooled in a process of passing through the first heat exchanger 910.

[0644] The duct ribs 920 can include a first duct rib 829a extending from a front direction to a rear direction, and a second duct rib 829b extending in an up-down direction to connect the first duct rib 829a.

[0645] The first duct rib 829a and the second duct rib 829b can be provided in plural, and the plural second duct ribs 829b can be configured to connect the plural first duct ribs 829a.

[0646] Figure 29 FIG. 10 is a cross-sectional view showing a case in which a duct sealing portion 880 of a laundry treating apparatus 1 according to an embodiment of the present application is inserted into a sealing seating portion 8324.

[0647] The cover insertion portion 8322 and the cover step portion 8223 can extend from the duct cover body 831 in a thickness direction Z2.

[0648] The length H10 by which the cover insertion portion 8322 extends from the duct cover body 831 can be greater than the length H11 by which the cover step portion 8223 extends from the duct cover body 831.

[0649] By having the cover insertion portion 8322 extend longer than the cover step portion 8223, not only can the duct cover body 831 be prevented from freely escaping from the moving duct 822 and the inflow duct 821, but also the duct cover body 831 can be firmly coupled to the moving duct 822 and the inflow duct 821.

[0650] In addition, the width W5 of the cover step portion 8223 can be greater than the width W6 of the cover insertion portion 8322. The width W6 of the cover insertion portion 8322 can be variously determined according to the width of the seal seating portion 8324.

[0651] Thus, the seal seating portion 8324 can be disposed between the cover step portion 8223 and the cover insertion portion 8322, and the duct seal portion 880 can be accommodated in the seal seating portion 8324. The distance between the inner circumferential surfaces of the seal seating portion 8324 can be equal to or less than the diameter of the duct seal portion 880, and thus the duct seal portion 880 can be coupled to the seal seating portion 8324 in a manner of interference fit.

[0652] Figure 30 FIG. 7 is an exploded perspective view of a duct cover portion 830 and a seal clamp member 1000 of a laundry treating apparatus 1 according to an embodiment of the present application.

[0653] The duct seal portion 880 can be formed in one body and seated in the seal seating portion 8324. The first seal seating portion 83241 can form a continuous surface with the second seal seating portion 83242, and can be formed of the same shape and material.

[0654] On the other hand, the laundry treating apparatus 1 according to an embodiment of the present application can include the seal clamp member 1000 that inserts the duct seal portion 880 into the duct cover portion 830.

[0655] The seal clamp member 1000 can include a clamp seating portion 1020 seated on a bottom surface of the duct cover portion 830, along the circumference of which the duct seal portion 880 is inserted, and a clamp insertion portion 1010 configured to be movable toward the clamp seating portion 1020 to apply pressure to the duct seal portion 880 toward the duct cover portion 830.

[0656] The pipe sealing portion 880 can be provided on an outer circumferential surface of the clamp seating portion 1020. The clamp seating portion 1020 can be seated in the pipe cover portion 830 in connection with the cover insertion portion 8322. The outer circumferential surface of the clamp seating portion 1020 can be configured in a shape corresponding to the outer circumferential surface of the cover insertion portion 8322.

[0657] The clamp insertion portion 1010 can be provided in the clamp seating portion 1020 on a side away from the pipe cover portion 830 in connection with the clamp seating portion 1020, and can be reciprocally movable in a manner approaching or away from the clamp seating portion 1020.

[0658] Specifically, the clamp insertion portion 1010 can be configured to reciprocally move in a height direction (Z direction) of the clamp seating portion 1020, and can insert the pipe sealing portion 880 into the sealing seating portion 8324 by pressing the pipe sealing portion 880.

[0659] Figure 31 FIG. 10 is a cross-sectional view illustrating a case where the sealing clamp member 1000 is seated in the pipe cover portion 830 in the laundry treatment apparatus 1 according to an embodiment of the disclosure.

[0660] The clamp seating portion 1020 can include a clamp seating extension portion 1025 configured to separate the pipe sealing portion 880 from the cover insertion portion 8322.

[0661] The clamp seating extension portion 1025 can extend toward the pipe cover body 831 on a side of the clamp seating portion 1020 facing the pipe cover body 831. The clamp seating extension portion 1025 can be configured to contact the bottom surface 831b of the pipe cover body 831.

[0662] A height H12 of the clamp seating extension portion 1025 can be greater than a length of the cover insertion portion 8322. Thereby, as illustrated, even if the clamp seating portion 1020 is seated on the bottom surface 831b of the pipe cover body 831, the pipe sealing portion 880 can be prevented from contacting the cover insertion portion 8322.

[0663] In addition, the clamp seating portion 1020 can be configured to contact the cover fastening portion 8393, and the clamp seating portion 1020 can be seated in a lower portion of the pipe cover body 831 supported by the cover fastening portion 8393.

[0664] On the other hand, the sealing clamp member 1000 can further include a clamp elastic member 1030 providing an elastic force to the clamp insertion portion 1010 and the clamp seating portion 1020.

[0665] The clamp elastic member 1030 can be disposed between the clamp insertion portion 1010 and the clamp seating portion 1020 in contact with the clamp insertion portion 1010 and the clamp seating portion 1020.

[0666] One end of the clamp elastic member 1030 can be in contact with the elastic member support portion 1023 of the clamp seating portion 1020, and the other end can be in contact with the clamp insertion portion 1010, thereby providing an elastic force to enable the clamp insertion portion 1010 to reciprocally move.

[0667] In addition, the clamp insertion portion 1010 can include an elastic member accommodation portion 1013 that accommodates the clamp elastic member 1030.

[0668] The elastic member accommodation portion 1013 can be provided with a plurality of elastic member accommodation portions 1013 at an inner circumferential surface of the clamp insertion portion 1010, which can be disposed at a predetermined distance W11 apart from each other. The clamp elastic member 1030 can be disposed to extend in an extension direction (height direction) of the elastic member accommodation portion 1013.

[0669] On the other hand, the clamp seating portion 1020 can include a seating insertion portion 1021 that seats the pipe sealing portion 880.

[0670] The seating insertion portion 1021 can be disposed such that one end thereof is inserted into the clamp insertion portion 1010 and the other end thereof is in contact with the cap insertion portion 8322. An outer circumferential surface of the seating insertion portion 1021 can be formed in a shape corresponding to an outer circumferential surface of the cap insertion portion 8322.

[0671] In addition, the clamp insertion portion 1010 can include a seating accommodation portion 1014 into which the seating insertion portion 1021 is inserted and a clamp guide portion 1012 that extends from an inner circumferential surface of the seating accommodation portion 1014 toward the clamp seating portion 1020 and is disposed to be insertable into the clamp seating portion 1020, when moving toward the clamp seating portion 1020.

[0672] The clamp guide portion 1012 can function as an element that determines a moving direction when the clamp insertion portion 1010 is inserted into the clamp seating portion 1020.

[0673] In addition, the clamp insertion portion 1010 can further include a sealing insertion portion 1011 that extends from an outer circumferential surface of the seating accommodation portion 1014 toward the sealing seating portion 8324 and applies a pressure to the pipe sealing portion 880 toward the sealing seating portion 8324.

[0674] The height H13 of the sealing insertion part 1011 can be less than the sum of the thickness H16 of the clamp seating part 1020 and the separation distance H14 between the clamp insertion part 1010 and the clamp seating part 1020.

[0675] Thus, the pipe sealing part 880 can be disposed between the sealing insertion part 1011 and the seating insertion part 1021.

[0676] Figure 32 FIG. 10 is a cross-sectional view illustrating a case where the pipe sealing part 880 is inserted into the pipe cover part 830 by the sealing clamp member 1000 in the laundry treating apparatus 1 according to an embodiment of the present application.

[0677] As the first sealing seating part 83241 and the second sealing seating part 83242 communicate with each other to form a continuous surface, and the first pipe sealing part 881 and the second pipe sealing part 882 are formed in a closed curve shape, the sealing clamp member 1000 can insert the pipe sealing part 880 into the sealing seating part 8324.

[0678] Specifically, in the sealing clamp member 1000 of Figure 19 If the clamp insertion part 1010 moves toward the clamp seating part 1020, the clamp guide part 1012 is inserted into the clamp seating part 1020, the seating insertion part 1021 is inserted into the seating receiving part 1014, and the sealing insertion part 1011 can move the pipe sealing part 880 to be inserted into the sealing seating part 8324.

[0679] In this case, the height H13 of the sealing insertion part 1011 can be equal to or less than the distance from the sealing seating part 8324 to the top surface of the clamp insertion part 1010. The lower end of the sealing insertion part 1011 can move to a position where the pipe sealing part 880 can be completely inserted into the sealing seating part 8324.

[0680] If the clamp insertion part 1010 inserts the pipe sealing part 880 into the sealing seating part 8324, the clamp elastic member 1030, which is pressed, can apply a force to the clamp insertion part 1010 to move away from the clamp seating part 1020, and the sealing insertion part 1011, which is inserted into the sealing seating part 8324, can be separated from the sealing seating part 8324.

[0681] The shapes and sizes of the clamp insertion part 1010 and the clamp seating part 1020 can be variously configured, and thus the clamp insertion part 1010 can insert the pipe sealing part 880 into the sealing seating part 8324.

[0682] In addition, the shapes and sizes of the clamp insertion portion 1010 and the clamp seating portion 1020 can be variously designed according to the shapes and sizes of the pipe sealing portion 880 and the sealing seating portion 8324 and the bottom surface of the pipe cover body 831.

[0683] On the other hand, as shown in Figure 30 the pipe cover portion 830 can be formed in correspondence with the shape of the circulation flow path portion 820, and the shapes of the cover insertion portion 8322 and the cover step portion 8323 into which the pipe sealing portion 880 of the pipe cover portion 830 is inserted can also be formed in correspondence with the circulation flow path portion 820.

[0684] For example, the cover insertion portion 8322 and the cover step portion 8323 of the pipe cover portion 830 can be formed with corners protruding in the outer side direction of the pipe cover portion 830 and corners recessed in the inner side direction of the pipe cover portion 830 according to the shape of the pipe cover portion 830.

[0685] That is, as shown in Figure 30 A and B, the pipe cover portion 830 can be formed with the cover insertion portion 8322 and the cover step portion 8323 recessed in the inner side of the pipe cover portion 830 in correspondence with the shape of the circulation flow path portion 820.

[0686] On the other hand, the pipe sealing portion 880 is pressed by the above-described sealing clamp member 1000 in a state of being seated outside the cover insertion portion 8322, and thus is inserted into the space formed between the cover insertion portion 8322 and the cover step portion 8323.

[0687] Here, the pipe sealing portion 880 is formed in an O-ring shape having a prescribed elasticity in a closed curve manner along the portion where the pipe cover portion 830 contacts the supply pipe 828.

[0688] On the other hand, in order for the pipe sealing portion 880 to be inserted between the cover insertion portion 8322 and the cover step portion 8323 by the sealing clamp member 1000, the pipe sealing portion 880 needs to be seated on the outer circumferential surface of the cover insertion portion 8322, and when the pipe sealing portion 880 is seated on the cover insertion portion 8322, a portion of the pipe sealing portion 880 located at the recessed corner position of the cover insertion portion 8322 can not be tightly attached to the cover insertion portion 8322 due to the elastic force of the pipe sealing portion 880, and thus can be in a state of being spaced apart.

[0689] If pressed by the sealing clamp member 1000 in such a case, the portion of the pipe sealing portion 880 that is not tightly attached to the cover insertion portion 8322 can escape from the clamp seating portion 1020 or from the space between the cover insertion portion 8322 and the cover step portion 8323, and thus can not be smoothly inserted into the space between the cover insertion portion 8322 and the cover step portion 8323.

[0690] Therefore, it is necessary to change or limit the position of the pipe sealing portion 880 so that the pipe sealing portion 880 is positioned in the space between the cover insertion portion 8322 and the cover step portion 8323 before the pipe sealing portion 880 is pressed by the sealing jig member 1000.

[0691] To this end, the cover step portion 8323 can further be formed with a locking protrusion 83231 for applying pressure to a portion of the pipe sealing portion 880 positioned at the recessed corner position of the cover insertion portion 8322 toward the recessed corner side of the cover insertion portion 8322.

[0692] Figures 33-34 is a perspective view showing the A and B parts of FIG. 8 in an enlarged manner. Figure 30

[0693] As shown, the outer circumferential surface of the pipe cover portion 830 (i.e., the outer circumferential surface of the cover insertion portion 8322) can be formed with a corner recessed inward of the pipe cover portion 830 corresponding to the shape of the circulation flow path portion 820. Therefore, the pipe sealing portion 880 seated in the cover insertion portion 8322 can be spaced apart from the cover insertion portion 8322 at the recessed corner position of the cover insertion portion 8322.

[0694] On the other hand, to minimize the case in which the pipe sealing portion 880 is spaced apart from the recessed corner position of the cover insertion portion 8322, the cover step portion 8323 facing the recessed corner of the cover insertion portion 8322 is formed with a locking protrusion 83231 applying pressure to the pipe sealing portion 880 toward the cover insertion portion 8322. The locking protrusion 83231 can be protruded in the extension direction of the cover step portion 8323, thereby preventing the pipe sealing portion 880 seated in the cover insertion portion 8322 from being spaced apart outward of the cover step portion 8323.

[0695] That is, as shown in FIG. 9, Figure 35 when seated in the cover insertion portion 8322 in order to insert the pipe sealing portion 880 into the pipe cover portion 830 by the sealing jig member 1000, pressure can be applied to a portion of the pipe sealing portion 880 toward the cover insertion portion 8322, so that the pipe sealing portion 880 seated in the cover insertion portion 8322 can be positioned between the cover insertion portion 8322 and the cover step portion 8323.

[0696] In addition, the side of the locking protrusion 83231 facing the cover insertion portion 8322 can be formed with a pipe sealing portion inclined surface 83232, so that the pipe sealing portion 880 can be moved in a sliding manner when the pipe sealing portion 880 is moved between the cover insertion portion 8322 and the cover step portion 8323 by the pressure of the sealing jig member 1000.

[0697] ​The pipe sealing portion inclined surface 83232 can be formed such that the end of the locking protrusion 83231 is more expanded than the interval between the lid insertion portion 8322 and the lid step portion 8323, and the interval between the pipe sealing portion inclined surface 83232 and the lid insertion portion 8322 is narrowed as it moves toward the space between the lid insertion portion 8322 and the lid step portion 8323.

[0698] Therefore, when the pipe sealing portion 880 is seated in the lid insertion portion and moved by the pressure of the sealing clamp member, the pipe sealing portion at the corner position of the recess of the lid insertion portion is guided toward the space between the lid insertion portion 8322 and the lid step portion 8323 by the pipe sealing portion inclined surface of the locking protrusion and the locking protrusion, and thus can be smoothly inserted between the lid insertion portion 8322 and the lid step portion 8323.

[0699] Although various embodiments of the present application have been described in detail above, it should be understood that many modifications will be possible without departing from the scope of the present application. Accordingly, the scope of the present application should be determined not by the embodiments described above but by the appended claims and equivalents thereof.
