Description

Technical Field

[0001] This invention belongs to the technical field of clothing processing equipment, specifically, it relates to a drainage system and clothing processing equipment for clothing processing. Background Technology

[0002] Existing washer-dryer combos use a drying airflow that flows into the drum module to remove moisture from inside. The humid airflow exiting the drum module is further cooled by a heat exchanger, causing the water vapor in the humid airflow to condense. The dried airflow can then be reheated and reintroduced into the drum module for continued drying of clothes. To prevent condensate from accumulating in the heat exchanger, the condensate needs to be drained.

[0003] In the current design, a condensate drain pipe is connected to the heat exchanger for discharging condensate. This drain pipe is connected to the outer cylinder of the drum module, allowing condensate to collect along the inner wall of the outer cylinder towards the bottom, and finally drain out through a drain outlet on the outer cylinder. However, in practical applications, it has been found that because the outlet of the condensate drain pipe is directly connected to the outer cylinder, some airflow carrying lint from the outer cylinder enters the condensate drain pipe during the clothes drying process. Due to the high air velocity inside the drum, the lint accumulated in the condensate drain pipe cannot be discharged with the water flow, thus affecting the condensate drainage efficiency. In severe cases, the condensate drain pipe can become blocked by lint, preventing condensate from draining, affecting clothes drying efficiency, and even causing lint to be blown into the heat exchanger.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. On the one hand, it provides a drainage system for clothing processing equipment, which can avoid blockage caused by lint entering the condensate drain pipe, and the structure at the connection between the condensate drain pipe and other pipes is stable and reliable.

[0006] Another aspect of the present invention provides a garment processing device with the above-mentioned drainage system, wherein the condensate drain pipe can bypass the outer cylinder and directly channel the condensate into the drainage path, and the installation of the condensate drain pipe is stable and reliable.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A drainage system for a garment processing device includes:

[0009] The outer cylinder drain pipe has its inlet end used to connect to the drain outlet of the outer cylinder;

[0010] A drainage device is connected to the outlet end of the outer cylinder drainage pipe for draining water outwards;

[0011] The condensate drain pipe has its inlet end connected to the heat exchanger and its outlet end connected to the outer cylinder drain pipe, with the connection position close to the outlet end of the outer cylinder drain pipe.

[0012] Furthermore, the outer cylinder drain pipe has an opening near the outlet end for connecting to the outlet end of the condensate drain pipe;

[0013] The outer cylinder drain pipe has a deformable region between its inlet end and the opening.

[0014] Furthermore, the outer cylinder drain pipe is a deformable flexible hose, and the opening is located on the side wall of the flexible hose near the outlet end;

[0015] Preferably, the outer cylinder drain pipe is a corrugated flexible hose with a corrugated structure in some areas, and the opening is staggered with the area having the corrugated structure.

[0016] Furthermore, the inlet end of the condensate drain pipe is connected to the condensate outlet located at the bottom of the heat exchanger; the condensate drain pipe extends a certain length below the heat exchanger in a horizontal or near-horizontal direction to form an inlet extension section.

[0017] Furthermore, the inlet end of the condensate drain pipe is provided with a first bracket to guide the condensate drain pipe to form the inlet extension section;

[0018] Preferably, the first bracket is sleeved on the outside of the condensate drain pipe, and a channel is defined inside the first bracket that bends from the condensate outlet in a horizontal or near-horizontal direction.

[0019] Furthermore, the condensate drain pipe extends downward at an angle after passing the end of the water inlet extension section, then bends downward and continues to extend to a height close to that of the outer cylinder drain pipe, and then bends towards the outer cylinder drain pipe and continues to extend, connecting with the outer cylinder drain pipe.

[0020] Preferably, the drainage system is provided with a second support, and the condensate drain pipe is partially installed on the second support and bent downward under the guidance of the second support;

[0021] And / or, the drainage system is provided with a third support, the downstream area of ​​the condensate drain pipe is installed on the third support, and extends further towards the outer cylinder drain pipe under the guidance of the third support;

[0022] Preferably, the condensate drain pipe includes a first condensate pipe and a second condensate pipe arranged sequentially along the condensate flow direction; the first condensate pipe and the second condensate pipe are connected in the area where the condensate drain pipe extends downward.

[0023] Furthermore, the drainage device has a filter and a pump assembly arranged sequentially along the drainage direction;

[0024] The condensate in the condensate drain pipe enters the filter of the drainage device through the outer cylinder drain pipe and is discharged outward under the drive of the pump assembly.

[0025] A garment processing device having the drainage system described above.

[0026] Furthermore, the heat exchangers of the garment processing equipment are spaced apart above the outer cylinder; the condensate drain pipe is connected to the condensate outlet at the bottom of the heat exchanger and extends into the housing of the garment processing equipment between the heat exchanger and the outer cylinder.

[0027] Preferably, the first support of the drainage system guides the condensate drain pipe to extend a certain length in a horizontal or near-horizontal direction below the heat exchanger, so that there is a gap between the condensate drain pipe and the outer cylinder.

[0028] Furthermore, the second bracket of the drainage system is installed on one side wall of the housing and connected to the upper region of the side wall; the condensate drain pipe bends downward under the guidance of the second bracket and extends downward along the side wall;

[0029] Preferably, the third support of the drainage system has:

[0030] The first guide section is provided and extends downward in the lower region of the sidewall;

[0031] The second guide section is disposed on the base of the housing and extends along the base toward the outer cylinder drain pipe.

[0032] A transition segment is used to connect the first guide segment and the second guide segment;

[0033] The condensate drain pipe extends from the lower region of the side wall, guided by the third bracket, to the outer cylinder drain pipe, where it bends.

[0034] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0035] In this invention, the condensate drain pipe is directly connected to the outer cylinder drain pipe, bypassing the outer cylinder to allow condensate to flow into the outer cylinder drain pipe. This avoids the problem of airflow in the outer cylinder carrying lint into the condensate drain pipe, causing blockage. The connection point between the condensate drain pipe and the outer cylinder drain pipe is close to the outlet end of the outer cylinder drain pipe, as far away from the outer cylinder as possible. This minimizes the impact of vibration from the outer cylinder, resulting in a more stable and reliable connection that is less prone to loosening and failure.

[0036] In this invention, the outer cylinder drain pipe is made of corrugated flexible tubing. The corrugated structure buffers the vibration of the outer cylinder, ensuring that the connection between the condensate drain pipe and the outer cylinder drain pipe is virtually free of wobbling, further guaranteeing a stable and reliable connection. A stable connection is even easier to achieve when the condensate drain pipe is connected to an area without a corrugated structure.

[0037] In this invention, the inlet end of the condensate drain pipe is installed on the first bracket. The first bracket guides the condensate drain pipe to extend along a basically horizontal surface within a certain length range, which can prevent the condensate drain pipe from drooping down and contacting the outer cylinder below the heat exchanger, and further reduce the impact of the vibration of the outer cylinder on the condensate drain pipe.

[0038] In this invention, the second and third supports are respectively positioned at the bends in the extension direction of the condensate drain pipe, which better guides the condensate drain pipe to extend along the predetermined path. By fixing the condensate drain pipe to the housing using the second and third supports, the housing essentially does not vibrate with the outer cylinder, further enhancing the structural stability of the condensate drain pipe. Guided by the second and third supports, the condensate drain pipe is positioned as close as possible to the inner wall of the housing, without affecting the existing internal structure.

[0039] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0055] like Figures 1 to 9 As shown, embodiments of the present invention provide a drainage system for a garment processing device, and a garment processing device having said drainage system.

[0056] Specifically, in this embodiment, the clothing processing equipment is a household appliance with a clothing drying function, such as a dryer or a washer-dryer combo.

[0057] As one specific embodiment of this invention, the garment processing equipment is a washer-dryer combo, having a housing 100 and a drum module disposed inside the housing 100. More specifically, the drum module includes an outer drum 200 and an inner drum (not shown in the figure) coaxially arranged, with the inner drum rotatably disposed inside the outer drum 200, and the central axes of the two being arranged substantially along a horizontal plane.

[0058] During the washing process, clothes are placed in the inner drum and water is placed in the outer drum 200. The rotation of the inner drum causes the clothes to be repeatedly lifted and then lowered, achieving the washing effect. A drain outlet 201 is located at the bottom of the outer drum 200. The drain outlet 201 is connected to the inlet of the drain device 420 via an outer drum drain pipe 410. The outlet of the drain device 420 is connected to an external drain pipe 430 extending to the outside of the casing 100. The highest point of the external drain pipe 430 is higher than the highest water level inside the outer drum 200, so that water in the drum module will not be drained away along the external drain pipe 430 during the washing process. When drainage is needed, the drain device 420 is activated to provide drainage power, which draws water from inside the outer drum 200 along the outer drum drain pipe 410 and discharges it along the external drain pipe 430.

[0059] The garment processing equipment also has drying air ducts at both ends connected to the outer drum 200. During garment drying, hot and humid air is drawn from inside the drum module into the drying air ducts. The heat exchanger 300 cools and condenses the hot and humid air, causing the water vapor it carries to condense and be released. The resulting dry air is then heated and reintroduced into the drum module to contact the garments. Through the continuous circulation of the drying airflow, the moisture in the garments is carried away, achieving the desired drying effect.

[0060] In a more specific embodiment, the clothing processing equipment is a heat pump washer-dryer combo machine. The heat exchanger 300 includes an evaporator of a heat pump device, and the dry air is heated through the condenser of the heat pump device.

[0061] In the specific structure of this embodiment, the heat exchanger 300 is disposed above the outer cylinder 200 and there is a certain gap between them to prevent the outer cylinder 200 from vibrating and colliding with the heat exchanger 300 during operation.

[0062] Furthermore, as the hot and humid air passes through the heat exchanger 300, condensate is produced and collects at the bottom of the heat exchanger 300. To prevent condensate from accumulating inside the heat exchanger 300, a condensate outlet 311 is provided at the bottom of the heat exchanger 300 for draining the condensate. The condensate outlet 311 is connected to a condensate drain pipe 500, thereby draining the condensate from the heat exchanger 300.

[0063] In one specific embodiment, the heat exchanger 300 includes a housing 310 and a heat exchange assembly (not shown in the figure) disposed inside the housing 310. For a heat pump washer-dryer combo, the heat exchange assembly is the evaporator of a heat pump device.

[0064] The housing 310 can serve as part of the drying air duct, through which hot and humid air passes and exchanges heat with the heat exchange components to cool down, resulting in the precipitation of condensate. The condensate outlet 311 is located on the bottom wall of the housing 310, where the condensate collects at the bottom of the housing 310 and is discharged through the condensate outlet 311 into the condensate drain pipe 500.

[0065] The condensate entering the condensate drain pipe 500 needs to be discharged from the garment processing equipment. If the condensate drain pipe 500 drains independently, it will add a drain outlet to the garment processing equipment, which is inconvenient for users to install the garment processing equipment. Existing technology also proposes a solution to connect the condensate drain pipe 500 to the outer drum 200, but this has the problem of lint entering the condensate drain pipe 500 and causing blockage.

[0066] To address the aforementioned problems, this embodiment provides a drainage system for the aforementioned clothing processing equipment, specifically employing the following technical solution.

[0067] In this embodiment, the drainage system includes at least an outer cylinder drain pipe 410, a drainage device 420, and a condensate drain pipe 500. The inlet end of the outer cylinder drain pipe 410 is connected to the drain outlet 201 of the outer cylinder 200, and the drainage device 420 is connected to the outlet end 412 of the outer cylinder drain pipe 410, allowing drainage to be directed outwards. The inlet end of the condensate drain pipe 500 is connected to the heat exchanger 300, and the outlet end 502 is connected to the outer cylinder drain pipe 410, with the connection point close to the outlet end 412 of the outer cylinder drain pipe 410.

[0068] In the above scheme, the condensate drain pipe 500 is directly connected to the outer drum drain pipe 410, bypassing the outer drum 200, and directly sending condensate into the outer drum drain pipe 410, which can then be discharged from the clothing processing equipment under the drive of the drain device 420. The connection position of the condensate drain pipe 500 and the outer drum drain pipe 410 is close to the outlet end 412 of the outer drum drain pipe 410, that is, the distance between this connection position and the drain port 201 of the outer drum 200 is as large as possible, which can reduce the impact of the vibration of the outer drum 200 on the connection position and avoid loosening or failure of the connection.

[0069] In a further embodiment, the outer cylinder drain pipe 410 has a deformable region, which is at least partially located between the inlet end of the outer cylinder drain pipe 410 and the connection point of the condensate drain pipe 500 on the outer cylinder drain pipe 410.

[0070] Specifically, the outer cylinder drain pipe 410 has an opening near the outlet end 412 for connecting to the outlet end 502 of the condensate drain pipe 500. The outer cylinder drain pipe 410 has a deformable area between its inlet end and the opening.

[0071] More specifically, the area between the inlet end of the outer cylinder drain pipe 410 and the opening may be entirely deformable, or it may be only partially deformable. The area between the opening and the outlet end 412 of the outer cylinder drain pipe 410 may or may not have a deformable area.

[0072] Thus, when the outer cylinder 200 vibrates during operation, the inlet end of the outer cylinder drain pipe 410 will sway synchronously with the vibration of the outer cylinder 200. However, since the outer cylinder drain pipe 410 has a deformable area upstream of the opening, it can buffer the vibration of the outer cylinder 200, thereby significantly reducing the vibration transmitted to the opening. In this way, the vibration amplitude at the opening, that is, at the connection point between the condensate drain pipe 500 and the outer cylinder drain pipe 410, is very small, or even almost non-existent, ensuring that the connection structure between the condensate drain pipe 500 and the outer cylinder drain pipe 410 is stable and reliable, and will not loosen.

[0073] In a preferred embodiment, the outer cylinder drain pipe 410 is entirely a deformable flexible hose, which facilitates manufacturing and assembly. An opening for connecting the condensate drain pipe 500 is located on the side wall of the flexible hose near the outlet end 412.

[0074] In one specific embodiment, the outer cylinder drain pipe 410 is a corrugated flexible hose with a corrugated structure 411 in a localized area. Specifically, the inlet end of the outer cylinder drain pipe 410 is arranged upwards and connected to the drain outlet 201, and extends forward from the inlet end. The portion of the outer cylinder drain pipe 410 extending forward has a corrugated structure 411 within a certain length range, while the area near the outlet end 412 does not have a corrugated structure 411. The outlet end 412 of the outer cylinder drain pipe 410 is inserted into the inlet of the drainage device 420.

[0075] The opening for connecting the condensate drain pipe 500 is positioned on the corrugated hose at a location that intersects with the area of ​​the corrugated hose having a corrugated structure 411. That is, the outlet end 502 of the condensate drain pipe 500 is connected to the area at the front of the outer cylinder drain pipe 410 where no corrugated structure 411 is provided.

[0076] With the above structure, the corrugated structure 411 can buffer the vibration of the outer cylinder 200, allowing the inlet end of the outer cylinder drain pipe 410 to sway with the vibration of the outer cylinder 200, while the outlet end 412 of the drain device 420 basically does not sway, thus making it less likely for the connection position of the condensate drain pipe 500 to loosen. At the same time, it is easier to process an opening for connecting the condensate drain pipe 500 in the area of ​​the outer cylinder drain pipe 410 where the corrugated structure 411 is not provided. The structure is simple and it is easier to achieve a stable connection between the condensate drain pipe 500 and the outer cylinder drain pipe 410.

[0077] In a further embodiment, the drainage device 420 includes a filter 421 and a pump assembly 422 arranged sequentially along the drainage direction. The pump assembly 422 provides drainage power, and the filter 421 filters out lint or other debris from the drainage flow, preventing lint or other debris from reaching the pump assembly 422 and affecting its operation.

[0078] The outlet end 502 of the condensate drain pipe 500 is connected to the outer cylinder drain pipe 410, which can send condensate water into the filter 421 along the outer cylinder drain pipe 410, and then discharge it outward under the drive of the pump assembly 422.

[0079] Clothing processing equipment typically installs filters or other filtration structures near the inlet of the drying duct to intercept lint carried in the airflow. However, it's possible that the airflow may still carry a small amount of lint as it passes through the heat exchanger 300, potentially causing the condensate to carry lint or small impurities. In the above solution, the condensate flows along the condensate drain pipe 500 into the outer drum drain pipe 410, and further flows along the outer drum drain pipe 410 into the filter 421 of the drain device 420. This filter intercepts any small impurities that may be present in the condensate, thus protecting the pump assembly 422. The filtration of the condensate and the drainage water is achieved through the same filter 421, without adding any additional filtration structures.

[0080] In a further embodiment, the inlet end of the condensate drain pipe 500 is connected to the condensate outlet 311 at the bottom of the heat exchanger 300, and the condensate drain pipe 500 extends a certain length below the heat exchanger 300 in a horizontal or near-horizontal direction to form an inlet extension section 501.

[0081] Specifically, the clothing processing equipment provided in this embodiment has the above-mentioned drainage system, wherein the condensate outlet 311 at the bottom of the heat exchanger 300 is located above the outer cylinder 200, and the upstream area of ​​the condensate drain pipe 500 extends towards the housing 100 between the heat exchanger 300 and the outer cylinder 200. By providing the condensate drain pipe 500 with a water inlet extension section 501 extending in a horizontal or near-horizontal direction, the condensate drain pipe 500 can be prevented from drooping down and contacting the outer cylinder 200.

[0082] In the above scheme, the water inlet extension section 501 can extend along a straight line, or it can extend on a horizontal or near-horizontal plane. Near-horizontal extension means that the water inlet extension section 501 is inclined downwards relative to the horizontal direction, and the inclination angle is controlled within 5°.

[0083] In one specific implementation, a first support 600 is provided at the water inlet end of the condensate drain pipe 500, and the first support 600 guides the condensate drain pipe 500 to form the aforementioned water inlet extension section 501 extending in a horizontal or near-horizontal direction.

[0084] In the specific structure, the first bracket 600 is sleeved on the outside of the condensate drain pipe 500, and a channel extending horizontally or nearly horizontally from the condensate outlet 311 is defined inside the first bracket 600. More specifically, the first bracket 600 is a bent and extended sleeve-shaped structure with one end open upwards and fixed at the condensate outlet 311.

[0085] In one detailed embodiment, one end of the first support 600 opens upward and connects to the condensate outlet 311. It then bends and extends to the left from the condensate outlet 311, with the extended end fitting around the outside of the inlet end of the condensate drain pipe 500. The inlet end of the condensate drain pipe 500 is supported by the first support 600, allowing it to continue extending along the direction of the extended end of the first support 600 to form the aforementioned inlet extension section 501, thus creating a gap between the condensate drain pipe 500 and the outer cylinder 200 without contact.

[0086] In another detailed embodiment, the inlet end of the condensate drain pipe 500 faces upward and is fixed to the condensate outlet 311 by a pipe clamp. One end of the first bracket 600 opens upward and connects to the condensate outlet 311. It bends and extends to the left from the condensate outlet 311 and is fitted onto the outside of the condensate drain pipe 500, thereby guiding the condensate drain pipe 500 to bend and extend along the channel defined inside the first bracket 600, forming an inlet extension section 501 below the heat exchanger 300, so that there is a gap between the condensate drain pipe 500 and the outer cylinder 200 without contact.

[0087] In the above scheme, the condensate drain pipe 500 does not contact the outer cylinder 200, which can prevent the vibration of the outer cylinder 200 during operation from affecting the installation stability of the condensate drain pipe 500.

[0088] In this embodiment, the heat exchanger 300 is located above the outer cylinder 200, the outer cylinder drain pipe 410 is located below the outer cylinder 200, and the inlet end of the condensate drain pipe 500 is higher than the outlet end 502. The condensate can flow into the outer cylinder drain pipe 410 along the condensate drain pipe 500 under the action of gravity without the need for additional driving force.

[0089] In a further embodiment, the condensate drain pipe 500 extends downwards at the end of the inlet extension section 501, then bends downwards and continues to extend downwards until it reaches a height close to that of the outer cylinder drain pipe 410. Afterwards, the condensate drain pipe 500 bends in the direction of the outer cylinder drain pipe 410 and continues to extend, eventually connecting with the outer cylinder drain pipe 410.

[0090] Furthermore, brackets are provided at the bends of the condensate drain pipe 500 to guide the condensate drain pipe 500 to bend and extend.

[0091] In one specific embodiment, the drainage system includes a second support 700 and a third support 800. A portion of the condensate drain pipe 500 is mounted on the second support 700, which guides the condensate drain pipe 500 to bend downwards. The downstream portion of the condensate drain pipe 500 is mounted on the third support 800, which guides the condensate drain pipe 500 to bend and extend towards the outer cylinder drain pipe 410.

[0092] In a more specific embodiment, the second bracket 700 and the third bracket 800 are respectively installed on the housing 100, thereby fixing the condensate drain pipe 500 to the housing 100. On the one hand, by fixing the condensate drain pipe 500 relative to the housing 100 at multiple positions along its extension direction, the condensate drain pipe 500 can be installed more stably inside the housing 100, reducing the shaking of the condensate drain pipe 500. On the other hand, it can guide the condensate drain pipe 500 to extend close to the inner wall of the housing 100, avoiding interference with other structures inside the housing 100.

[0093] In a further embodiment, the condensate drain pipe 500 includes a first condensate pipe 510 and a second condensate pipe 520, which are separately arranged and connected by a connecting joint 530. The first condensate pipe 510 and the second condensate pipe 520 are arranged sequentially along the flow direction of the condensate, and their connection point is located in the area where the condensate drain pipe 500 extends downwards.

[0094] Specifically, the first condensate pipe 510 is guided by the first bracket 600 to form a water inlet extension section 501, and then extends downward at an angle. The second bracket 700 is set near the extension end of the first condensate pipe 510 to guide the first condensate pipe 510 to bend downward, and a connecting joint 530 is connected at the lower end of the first condensate pipe 510.

[0095] The second condensate pipe 520 extends downward from the connecting joint 530, and the third bracket 800 is set in the downstream area of ​​the second condensate pipe 520 to guide the second condensate pipe 520 to bend and extend towards the location of the outer cylinder drain pipe 410.

[0096] In the above scheme, the first condensate drain pipe 510 is fixed by the second bracket 700, and the second condensate drain pipe 520 is fixed by the third bracket 800. In this way, the first condensate drain pipe 510 and the second condensate drain pipe 520 are respectively fixed on the housing 100, ensuring the stable installation of the condensate drain pipe 500.

[0097] In this embodiment, the housing 100 of the garment processing equipment includes several side walls and a base 140 connected to the bottom of the side walls. A second bracket 700 is mounted on one of the side walls of the housing 100 and connected to the upper region of that side wall. A third bracket 800 is mounted in the lower region of the housing 100, partially connected to the lower region of the aforementioned side wall and partially connected to the base 140.

[0098] Specifically, the side walls of the housing 100 include a left side wall 110, a rear side wall 120, and a right side wall 130 connected in sequence. As one specific embodiment, the left side wall 110, the rear side wall 120, and the right side wall 130 are integrally connected structures.

[0099] In one specific embodiment of this invention, the second bracket 700 is mounted on the left side wall 110 and connected to the upper region of the left side wall 110. The condensate drain pipe 500 extends from between the heat exchanger 300 and the outer cylinder 200 toward the left side wall 110, is guided downward by the second bracket 700 and bends downward, and continues to extend downward along the left side wall 110.

[0100] The third bracket 800 has a first guide section 810, a transition section 830, and a second guide section 820 connected in sequence. The first guide section 810 is located in the lower region of the left side wall 110 and extends downwards. The second guide section 820 is located on the base 140 of the housing 100 and extends along the base 140 towards the outer cylinder drain pipe 410. The transition section 830 is inclined, with one end connected to the first guide section 810 and the other end connected to the second guide section 820. The condensate drain pipe 500 extends downwards along the left side wall 110 to the installation position of the third bracket 800, and then continues to extend along the third bracket 800, bending towards the outer cylinder drain pipe 410 under the guidance of the third bracket 800, ultimately connecting with the outer cylinder drain pipe 410.

[0101] In a more specific embodiment, the second bracket 700 is located on the upper part of the left side wall 110 near the front end. The first condensate pipe 510 extends to the left and tilts forward after being led out from the condensate outlet 311 at the bottom of the heat exchanger housing 310, and the end area is fixed to the second bracket 700.

[0102] The first condensate pipe 510 can be a flexible hose, with one end fixed by the first bracket 600 and the area near the other end fixed by the second bracket 700, effectively preventing the first condensate pipe 510 from sagging and contacting the outer cylinder 200.

[0103] The end region of the first condensate pipe 510 bends downward under the guidance of the second bracket 700. The end of the second condensate pipe 520 is connected to the end of the first condensate pipe 510 through the connecting joint 530. It extends downward along the front edge of the left side wall 110 and bends towards the outer cylinder drain pipe 410 under the guidance of the third bracket 800, and finally connects to the outer cylinder drain pipe 410.

[0104] More specifically, the base 140 has a base plate 141 and a support plate 142 formed by bending upward from the front side of the base plate 141. The first guide section 810 of the third bracket 800 extends downward along the front edge of the left side wall 110 at its lower portion, while the transition section 830 and the second guide section 820 extend along the upper edge of the support plate 142. The downstream region of the second condensate pipe 520 bends and extends to the right along the third bracket 800, with the portion extending from the right end of the second guide section 820 tilting rearward and connecting to the outer cylinder drain pipe 410.

[0105] Preferably, the right end region of the second guide section 820 is inclined to the rear, guiding the second condensate pipe 520 to extend inclined to the rear and connect to the outer cylinder drain pipe 410.

[0106] In the detailed structure of this embodiment, the front end of the left side wall 110 has a bent portion 111 that bends to the right. The second bracket 700 and the first guide section 810 of the third bracket 800 are respectively fixed on the bent portion 111. The second guide section 820 of the third bracket 800 is fixed on the support plate 142.

[0107] Specifically, in combination Figure 3 , Figure 6 and Figure 7 As shown, the second bracket 700 provides a downwardly bent guide groove 702. When the second bracket 700 is installed on the housing 100, the open side of the guide groove 702 faces the left side wall 110. In actual assembly, the end area of ​​the first condensate pipe 510 can be embedded into the guide groove 702 first, and then the second bracket 700 can be fixed to the bent portion 111 at the front end of the left side wall 110. More specifically, the guide groove 702 has first buckles 701 on both sides that are relatively arranged and whose spacing gradually narrows. The first buckles 701 are respectively provided at both ends of the guide groove 702, and the first condensate pipe 510 is fixed to the second bracket 700 by the first buckles 701.

[0108] The second bracket 700 extends laterally at the top and longitudinally at the bottom, with a rounded transition in the middle. Preferably, the laterally extending portion of the upper part of the second bracket 700 is inclined at a certain angle towards the inside of the housing 100 relative to the plane of the left side wall 110, which better matches the extension direction of the first condensate pipe 510. A mounting structure 710 for connecting with the bend 111 is provided on the longitudinally extending portion of the lower part of the second bracket 700, thereby fixing the second bracket 700 to the left side wall 110.

[0109] In one specific embodiment, the upper region of the bent portion 111 has a first mounting portion 1111. The mounting structure 710 is fixedly mounted to the first mounting portion 1111, and the second bracket 700 is mounted to the left side wall 110. The mounting structure 710 has a snap-fit ​​portion 711 located on the front side of the second bracket 700. The snap-fit ​​portion 711 protrudes from the front side of the main body of the second bracket 700 and extends to the right. The bent portion 111 is inserted into the space between the snap-fit ​​portion 711 and the main body of the second bracket 700 at the position where the first mounting portion 1111 is located. The rear side of the snap-fit ​​portion 711 has at least two protruding insertion portions 712. The first mounting portion 1111 has corresponding through holes. The insertion portions 712 are inserted into the through holes, so that the second bracket 700 and the bent portion 111 are fixed relative to each other.

[0110] Furthermore, the snap-fit ​​portion 711 is also provided with a fastening portion 713, and the first assembly portion 1111 has a mating hole corresponding to the fastening portion 713. By passing a fastener through the fastening portion 713 and the mating hole, the second bracket 700 can be securely installed on the left side wall 110.

[0111] Combination Figure 3 , Figure 8 and Figure 9 As shown, the third bracket 800 provides a rearward-opening mounting groove 805, and the downstream area of ​​the second condensate pipe 520 is fixed in the mounting groove 805.

[0112] The mounting groove 805 extends downward from the front end of the left side wall 110, then bends to the right, extending obliquely to the lower right along the upper edge of the support plate 142, and then continues to extend to the right along the upper edge of the support plate 142. The end of the mounting groove 805, i.e., the right end region of the second guide section 820, is slightly inclined to the rear, so that the second condensate pipe 520 extends obliquely to the rear from the end of the mounting groove 805.

[0113] The mounting groove 805 has two oppositely arranged second buckles 804 with gradually narrowing intervals. Multiple sets of second buckles 804 are arranged and distributed at intervals along the extension direction of the mounting groove 805, so as to fix the second condensate pipe 520 in the mounting groove 805 of the third bracket 800 through the second buckles 804.

[0114] Preferably, at least one set of second latches 804 are respectively provided in the area of ​​the mounting groove 805 corresponding to the first guide section 810, the transition section 830 and the second guide section 820.

[0115] Furthermore, the third bracket 800 is provided with several fixing parts, which fix the third bracket 800 to the housing 100. Specifically, the fixing parts protrude from the front side of the third bracket 800 and are installed in conjunction with corresponding structures on the housing 100.

[0116] In one specific embodiment, the upper end of the first guide section 810 is provided with a first fixing part 801, and the lower end is provided with a second fixing part 802. The bent part 111 at the front end of the left side wall 110 is provided with a second assembly part 1112 and a third assembly part 1113 respectively corresponding to the first fixing part 801 and the second fixing part 802, for fixing the first guide section 810 of the third bracket 800.

[0117] Specifically, the second assembly part 1112 and the third assembly part 1113 each have through holes opened on the bending part 111, and the first fixing part 801 and the second fixing part 802 are respectively inserted into the through holes on the second assembly part 1112 and the third assembly part 1113, thereby fixing the first guide section 810 of the third bracket 800 to the rear side of the bending part 111.

[0118] The second guide section 820 has a third fixing part 803 in its central region for assembly with the support plate 142. Correspondingly, the support plate 142 has a fourth assembly part 1421 that mates with the third fixing part 803. Specifically, the transition section 830 and the second guide section 820 are located above the support plate 142 and extend along the upper edge of the support plate 142. The second guide section 820 has a downwardly protruding protrusion 821 in its central region, and the third fixing part 803 protrudes from the front surface of the protrusion 821. The fourth assembly part 1421 has a through hole in the support plate 142, and the third fixing part 803 is inserted into the through hole in the fourth assembly part 1421 to achieve relative fixation between the second guide section 820 and the support plate 142.

[0119] In a further embodiment, the front end of the filter 421 is mounted on the support plate 142 and extends out to the outside of the housing 100 through the through-hole 1422 provided on the support plate 142.

[0120] With the above structure, on the one hand, the support plate 142 can support and fix the drainage device 420, making the connection position between the outer cylinder drain pipe 410 and the drainage device 420 more stable and less prone to shaking. This, in turn, makes the connection structure between the condensate drain pipe 500 and the outer cylinder drain pipe 410 near the drainage device 420 more stable and reliable. On the other hand, the front end of the filter 421 is exposed on the front side of the housing 100, making it easy for the user to open the filter 421 and clean the filter components, preventing the accumulation of lint and debris that could clog the drainage device 420.

[0121] The garment processing equipment provided in this embodiment, during the washing process, especially in the spin-drying stage, utilizes the corrugated structure 411 of the outer drum drain pipe 410 to buffer the vibration of the outer drum 200, preventing significant vibration at the outlet end 412 of the outer drum drain pipe 410. The condensate drain pipe 500 is connected to the outer drum drain pipe 410 near the outlet end 412, and the connection point is virtually vibration-free, effectively preventing loose connections and ensuring stable and reliable pipe connections, preventing leaks due to connection failure.

[0122] During the clothes drying process, driving air circulates between the drum module and the drying air duct. The hot and humid air drawn from the drum module is cooled by the heat exchanger 300, and condensation occurs. The condensation flows out from the condensation outlet 311 at the bottom of the shell 310 of the heat exchanger 300, and flows downward along the condensation drain pipe 500 under the action of gravity, and is sent into the outer drum drain pipe 410.

[0123] At the start of drying, or after a certain period of drying, the drainage device 420 is turned on and runs continuously. This drives the condensate entering the outer drum drain pipe 410 through the filter 421 and pump assembly 422 of the drainage device 420, and then discharges it from the garment processing equipment along the outer drain pipe 430. The continuous operation of the drainage device 420 provides drainage power, which can prevent excessive condensate from entering the outer drum 200 and inner drum along the outer drum drain pipe 410 and wetting the clothes inside the drum.

[0124] In the preferred embodiment, the drain device 420 is activated after a certain period of drying has begun. Since no condensate has entered the outer cylinder drain pipe 410 at the start of drying, activating the drain device 420 at this time might draw in a large amount of air, generating operating noise and affecting the user experience. After a certain period of drying has begun, condensate gradually precipitates inside the heat exchanger 300 and flows along the condensate drain pipe 500 to the outer cylinder drain pipe 410. Activating the drain device 420 at this point significantly reduces its operating noise.

[0125] In the above scheme, the interval between starting drying and turning on the drain device 420 can be preset in the control system of the garment processing equipment. Specifically, the value of this interval can be determined through pre-testing, as long as it ensures that the condensate entering the outer drum drain pipe 410 along the condensate drain pipe 500 does not overflow the inlet end of the outer drum drain pipe 410 between turning on the drain device 420.

[0126] The drainage system and clothing processing equipment provided in this embodiment direct the condensate generated at the heat exchanger 300 into the existing drainage path of the clothing processing equipment via the condensate drain pipe 500. Furthermore, the drainage device 420 is shared by the condensate drain and the washing water drain, simplifying the overall drainage structure. The condensate drain pipe 500 is connected to the outer drum drain pipe 410, bypassing the outer drum 200, effectively preventing airflow from blowing lint into the condensate drain pipe 500 and causing blockage, thus affecting the drying effect.

[0127] The outlet end 502 of the condensate drain pipe 500 is connected to the outer cylinder drain pipe 410 near the outlet end 412. The connection position is minimally affected by the vibration of the outer cylinder 200. Combined with the corrugated structure 411 of the outer cylinder drain pipe 410 to buffer the vibration of the outer cylinder 200, the connection position between the condensate drain pipe 500 and the outer cylinder drain pipe 410 is virtually free of shaking, ensuring a stable and reliable connection that will not easily loosen or leak.

[0128] The inlet end of the condensate drain pipe 500 is mounted on the first bracket 600, which prevents the condensate drain pipe 500 from drooping below the heat exchanger 300 and contacting the outer cylinder 200, further reducing the impact of the vibration of the outer cylinder 200 on the condensate drain pipe 500. The condensate drain pipe 500 is fixed to the housing 100 by the second bracket 700 and the third bracket 800, ensuring that the housing 100 does not vibrate with the outer cylinder 200, further enhancing the structural stability of the condensate drain pipe 500. Furthermore, the second bracket 700 and the third bracket 800 are respectively positioned at the bends in the extension direction of the condensate drain pipe 500, guiding its extension direction and ensuring that the extension of the condensate drain pipe 500 is as close as possible to the inner wall of the housing 100, minimizing its occupation of the internal space of the housing 100 and not affecting the existing internal structure of the housing 100.
