[0045] Currently, in related garment processing devices, a filter is usually installed at the drain outlet to filter out impurities such as microfibers in the water discharged from the garment processing device. However, existing filter devices are prone to clogging and cannot promptly remind users to replace or clean the filter device, which causes the filter device to fail to filter smoothly, and consequently, the garment processing device cannot drain smoothly.

[0046] The clothing processing device provided in this embodiment of the invention can be a washing machine, a dryer, or a washer-dryer combo. The clothing processing device mainly includes a cabinet, a drum, a drain pipe, and a filter.

[0047] The box is constructed as the outer shell of the clothing processing device.

[0048] The drum is located inside the box, and a clothes handling chamber is formed inside the drum, which can be used to wash or dry clothes.

[0049] The drain pipe is located outside the cylinder. One end of the drain pipe is connected to the inside of the cylinder, that is, one end of the drain pipe is connected to the clothing processing chamber, and the other end of the drain pipe extends outside the box, thereby draining the sewage in the clothing processing chamber out of the box.

[0050] The filtration device is located outside the housing and is connected to the drain pipe. Therefore, wastewater from the laundry processing chamber can enter the filtration device for filtration after being discharged from the housing, and then be discharged through the filtration device. This achieves the filtration of microparticles in the wastewater, reducing the emission of microparticles into the environment and thus reducing the damage of microparticles to the ecological environment.

[0051] Figure 1 This is a schematic diagram of the structure of a filtration device according to an embodiment of the present invention. Figure 2 yes Figure 1A schematic diagram of the structure of the middle shell 1. Figure 3 yes Figure 2 A structural diagram from another perspective. Figure 4 yes Figure 1 A sectional view.

[0052] Please see Figures 1 to 4 As shown, the filtration device provided in this embodiment of the invention mainly includes a housing 1, a filter element 2, a water distributor 6, an end cap 3, a warning module 4, and an upper cover 5.

[0053] The housing 1 is constructed as the outer shell of the filter device. A receiving groove 10 is formed inside the housing 1. The receiving groove 10 is used to provide installation space for components such as the filter element 2, end cap 3, top cover 5 and warning module 4. At the same time, the receiving groove 10 is used to contain and filter sewage.

[0054] A water inlet pipe 11 is provided on the outer wall of the housing 1. The water inlet pipe 11 is used to connect with the drain pipe, so that the sewage discharged from the drain pipe is introduced into the receiving tank 10 inside the housing 1 for filtration. That is, the sewage discharged from the clothing treatment device can be introduced into the receiving tank 10 inside the housing 1 for filtration through the water inlet pipe 11.

[0055] A water outlet pipe 12 is provided on the outer wall of the housing 1. The water outlet pipe 12 is used to discharge the filtered water in the receiving tank 10 to the outside of the housing 1. That is, the filtered water in the receiving tank 10 can be discharged to the outside of the housing 1 through the water outlet pipe 12.

[0056] In some embodiments, inlet pipes 11 are spaced above outlet pipes 12. Inlet pipes 11 communicate with the upper space of the receiving tank 10, and outlet pipes 12 communicate with the lower space of the receiving tank 10. Therefore, wastewater to be filtered can be introduced from the upper space of the receiving tank 10 through inlet pipes 11, filtered, and then flow into the lower region of the receiving tank 10, and subsequently discharged from the housing 1 through outlet pipes 12.

[0057] Figure 5 yes Figure 4 A structural diagram in another state. Figure 6 yes Figure 5 A magnified structural diagram of region A in the middle. Figure 7 yes Figure 4 A schematic diagram of the structure of the middle filter element 2.

[0058] Please see Figures 4 to 7As shown, the filter element 2 is disposed in the receiving tank 10, and a filter tank 20 with a top opening is formed inside the filter element 2. Wastewater introduced into the receiving tank 10 through the inlet pipe 11 can enter the filter tank 20 from the top, and then be filtered through the peripheral side wall and bottom wall of the filter tank 20. The filtered water can pass through the peripheral side wall and bottom wall of the filter tank 20, and then enter the receiving tank 10 area outside the filter tank 20, and then be discharged to the outside of the housing 1 through the outlet pipe 12.

[0059] In some embodiments, the bottom of the filter element 2 is spaced apart from the bottom sidewall of the receiving tank 10. Therefore, the water filtered and passed through the bottom wall of the filter tank 20 can flow directly to the bottom area of ​​the receiving tank 10 and then be discharged outside the housing 1 through the water outlet pipe 12.

[0060] In some embodiments, the outer periphery of the filter element 2 is spaced apart from the peripheral sidewall of the receiving tank 10. Therefore, water filtered and permeated from the peripheral sidewall of the filter tank 20 can flow through the gap between the outer periphery of the filter element 2 and the peripheral sidewall of the receiving tank 10 to the bottom region of the receiving tank 10, and then be discharged outside the housing 1 through the water outlet pipe 12.

[0061] It should be noted that in other embodiments, the filter tank 20 may filter only through its peripheral sidewalls or only through its bottom wall.

[0062] Please see Figure 7 As shown, in some embodiments, the filter element 2 includes a filter frame 21 and a filter screen 22 disposed on the filter frame 21. The filter frame 21 is a cylindrical structure with an open top, and a filter groove 20 is formed within the filter frame 21. The peripheral and bottom walls of the filter frame 21 have perforated areas. The filter screen 22 is disposed in each of the perforated areas, and the filter screen 22 is densely covered with filter holes. The filter screen 22 can be used to filter the washing water discharged from the laundry treatment device, filtering out microparticles in the washing water. Therefore, the water in the filter groove 20 can be filtered through the filter screen 22 in each perforated area, passing through the filter holes on the filter screen 22 and entering the receiving groove 10, thereby achieving the filtration of microparticles in the wastewater, reducing the emission of microparticles into the environment, and thus reducing the damage of microparticles to the ecological environment.

[0063] Please see Figures 4 to 7As shown, in some embodiments, the filter element 2 includes a first filter element 2a and a second filter element 2b. The second filter element 2b is spaced around the outer periphery of the first filter element 2a, i.e., the first filter element 2a and the second filter element 2b are arranged with an inner and outer gap. The filter tank 20 includes a first filter tank 20a formed in the first filter element 2a and a second filter tank 20b formed in the second filter element 2b, with the first filter element 2a disposed in the second filter tank 20b. Meanwhile, the filter holes on the second filter element 2b are smaller than those on the first filter element 2a. Therefore, wastewater introduced through the inlet pipe 11 can first be introduced into the first filter tank 20a for filtration, filtering out microparticles in the wastewater. The water that passes through the first filter tank 20a then enters the second filter tank 20b for further filtration, filtering out even smaller microparticles in the wastewater. The water that passes through the second filter tank 20b then enters the receiving tank 10 and is discharged outside the housing 1 through the receiving tank 10.

[0064] It should be noted that in other embodiments, the filter element 2 may also include only the first filter element 2a, that is, the filter element 2 may include only the first filter tank 20a.

[0065] Figure 8 yes Figure 4 A schematic diagram of the structure of the central water distributor 6. Figure 9 yes Figure 8 A sectional view.

[0066] Please see Figures 4 to 9 As shown, the water distributor 6 is located on top of the filter element 2 and at the top opening of the filter tank 20. A water distribution groove 60 is recessed on the top surface of the water distributor 6, and multiple water distribution ports 61 are provided on the bottom surface of the water distribution groove 60. These ports 61 are arranged circumferentially around the center of the water distributor 6 and also circumferentially around the center of the filter tank 20. Wastewater introduced through the inlet pipe 11 can first be introduced into the water distribution groove 60, and then dispersed into different areas of the filter tank 20 through the multiple water distribution ports 61, thereby improving the filtration efficiency of the filter tank 20.

[0067] In some embodiments, the water inlets 61 are arranged at an angle and extend downwards at an angle toward the peripheral sidewall of the filter tank 20. Therefore, water in the water distribution tank 60 inside the water distributor 6 can be directed at an angle to the inner wall of the filter tank 20 through multiple water inlets 61 to impact the inner sidewall of the filter tank 20, thereby rinsing the filter screen 22 on the inner wall of the filter tank 20 and preventing the filter tank 20 from becoming clogged to a certain extent.

[0068] In some embodiments, the water inlets 61 are provided in two sets, each set of water inlets 61 including a plurality of water inlets 61 arranged in a ring at intervals, and the two sets of water inlets 61 are arranged in an inner and outer interval. The cooperation of the two sets of water inlets 61 can improve the water guiding efficiency of the water distribution tank 60, thereby improving the filtration efficiency of the filter tank 20 and improving the rinsing effect on the inner wall of the filter tank 20.

[0069] In some embodiments, the water distributor 6 is located at the top of the first filter element 2a, that is, at the top opening of the first filter tank 20a. Therefore, water in the water distribution tank 60 inside the water distributor 6 can be first dispersedly introduced into the first filter tank 20a for filtration through multiple water outlets 61, and then pass through the first filter tank 20a and be introduced into the second filter tank 20b for filtration.

[0070] It should be noted that in other embodiments, the water distributor 6 is located at the top of the second filter element 2b, that is, the water distributor 6 is located at the top opening of the second filter tank 20b.

Figure 12 yes Figure 11 A schematic diagram of the structure of the middle cover 3. Figure 13 yes Figure 12 A structural diagram from another perspective. Figure 14 yes Figure 12 A sectional view.

[0072] Please see Figures 4 to 14 As shown, end cap 3 is located at the top opening of the receiving tank 10, and end cap 3 can seal the top opening of the receiving tank 10. End cap 3 has a water inlet channel 30, the inlet end of which is connected to the water inlet pipe 11, which in turn connects to the wastewater to be filtered. End cap 3 is located above the filter element 2, and water distributor 6 is located between the bottom of end cap 3 and the top of the filter tank 20. The outlet end of the water inlet channel 30 is connected to the filter tank 20, allowing the washing water introduced by the water inlet pipe 11 to enter the water distribution tank 60 of the water distributor 6. The water is then introduced into the filter tank 20 through multiple water outlets 61 for filtration. The filtered water enters the receiving tank 10 and is discharged from the housing 1 through the receiving tank 10 and the outlet pipe 12.

[0073] Please see Figures 6 to 12As shown, in some embodiments, a first sealing groove 31 is provided on the outer peripheral wall of the end cap 3. The first sealing groove 31 is annular and arranged around the outer peripheral wall of the end cap 3. A first sealing ring 311 is provided in the first sealing groove 31. The first sealing ring 311 is annular and is sealed within the first sealing groove 31. When the end cap 3 is installed at the top opening of the receiving groove 10, the first sealing ring 311 can be clamped between the groove wall of the first sealing groove 31 and the peripheral side wall of the receiving groove 10, thereby sealing the gap between the outer peripheral wall of the end cap 3 and the peripheral side wall of the receiving groove 10, and thus sealing the top opening of the receiving groove 10.

[0074] In some embodiments, a second sealing groove 32 is provided on the outer peripheral wall of the end cap 3. The second sealing groove 32 is annular and arranged around the outer peripheral wall of the end cap 3. A second sealing ring 321 is provided in the second sealing groove 32. The second sealing ring 321 is annular and is sealed within the second sealing groove 32. When the end cap 3 is installed at the top opening of the receiving groove 10, the second sealing ring 321 can be clamped between the groove wall of the second sealing groove 32 and the peripheral side wall of the receiving groove 10, thereby cooperating with the first sealing ring 311 to seal the gap between the outer peripheral wall of the end cap 3 and the peripheral side wall of the receiving groove 10.

[0075] In some embodiments, the second sealing groove 32 is spaced above the first sealing groove 31, and the inlet end of the water inlet channel 30 is located in the space between the first sealing groove 31 and the second sealing groove 32. Therefore, when the end cap 3 is installed at the top opening of the receiving groove 10, the inner end of the water inlet pipe 11 is connected to the inlet end of the water inlet channel 30, and the washing water introduced by the water inlet pipe 11 can be sealed in the space between the first sealing groove 31 and the second sealing groove 32, which can prevent the washing water from directly entering the receiving groove 10 or overflowing from the upper side of the end cap 3 to the outside of the housing 1.

[0076] In some embodiments, a water inlet groove 33 is formed in the space between the first sealing groove 31 and the second sealing groove 32. The water inlet groove 33 is annular and arranged around the outer peripheral wall of the end cap 3, and the inlet end of the water inlet channel 30 is connected to the water inlet groove 33. When the end cap 3 is installed at the top opening of the receiving groove 10, the water inlet groove 33 is sealed between the first sealing ring 311, the second sealing ring 321, and the peripheral sidewall of the receiving groove 10. The inner end of the water inlet pipe 11 is connected to the water inlet groove 33, and thus the inlet end of the water inlet channel 30 is connected through the water inlet groove 33. Therefore, when installing the end cap 3, it is not necessary to force the inlet end of the water inlet channel 30 to be directly opposite the inner end of the water inlet pipe 11. The water inlet groove 33 can also connect the inlet end of the water inlet channel 30 to the water inlet pipe 11, improving the convenience of use for users.

[0077] It should be noted that in other embodiments, multiple water inlet channels 30 can be provided, with the inlet ends of the multiple water inlet channels 30 arranged at intervals on the peripheral sidewall of the end cover 3, and all connected to the water inlet trough 33. The outlet ends of the multiple water inlet channels 30 are all located on the bottom surface of the end cover 3 and connected to the filter tank 20. Therefore, the water introduced into the water inlet trough 33 by the water inlet pipe 11 can be introduced into the filter tank 20 through the multiple water inlet channels 30.

[0078] Figure 15 yes Figure 4 A schematic diagram of the structure of the warning module 4. Figure 16 yes Figure 15 A sectional view.

[0079] Please see Figures 4 to 16 As shown, the end cap 3 has a through mounting hole 34, and the warning module 4 is installed in the mounting hole 34. The warning module 4 includes at least a warning post 41 and a return spring 42. The warning post 41 is movably disposed in the mounting hole 34 and can move up and down along the extension direction of the mounting hole 34. The return spring 42 is connected to the warning post 41 and is used to drive the warning post 41 downward along the mounting hole 34, thereby allowing the lower end of the warning post 41 to block the bottom port of the mounting hole 34.

[0080] When the filter tank 20 inside the filter element 2 becomes clogged, the inlet pipe 11 still guides wastewater into the filter tank 20 through the inlet channel 30, causing the water level in the filter tank 20 to rise. The water level gradually submerges the distributor 6 and the lower port of the mounting hole 34, increasing the water pressure at the bottom port of the mounting hole 34. When the water pressure at the bottom port of the mounting hole 34 increases to a preset threshold, the warning column 41, under the action of water pressure, overcomes the elastic force of the return spring 42 and moves upward, protruding onto the top of the end cover 3, reminding the user to replace the filter element 2 or clean the filter tank 20 in time.

[0081] Please see Figures 4 to 6As shown, in some embodiments, an overflow hole 35 is provided on the outer wall of the end cap 3. The inner end of the overflow hole 35 is connected to the mounting hole 34, and the outer end of the overflow hole 35 is connected to the receiving groove 10 of the end cap 3. The overflow hole 35 is close to the bottom port of the mounting hole 34. Therefore, when the lower end of the warning post 41 blocks the bottom port of the mounting hole 34, the warning post 41 can simultaneously block the overflow hole 35. When the filter tank 20 inside the filter element 2 becomes clogged, the warning column 41 can move upward along the mounting hole 34 under the action of water pressure, so that the bottom port of the mounting hole 34 is opened, and the overflow hole 35 is also opened. This allows the top of the filter tank 20 to connect to the overflow hole 35 through the bottom port of the mounting hole 34, and to connect to the receiving tank 10 in the outer area of ​​the filter element 2 through the overflow hole 35. This allows the sewage entering the filter tank 20 to be guided into the receiving tank 10 in the outer area of ​​the filter element through the bottom port of the mounting hole 34 and the overflow hole 35 in sequence, and then directly discharged to the outside of the housing 1 through the bottom area of ​​the receiving tank 10. This effectively ensures the smooth flow of water in the water inlet channel 30 and the water inlet pipe 11 inside the filter device, thereby ensuring that the clothing treatment device connected to the water inlet pipe 11 can drain smoothly and preventing the clothing treatment device from becoming clogged.

[0082] It should be noted that the overflow hole 35, in conjunction with the mounting hole 34 and the warning module 4, allows the filter device to promptly remind the user to replace or clean the filter element 2 and filter tank 20 when blockage occurs, not only through the warning post 41 protruding from the top of the end cover 3, but also to restore the filtration function of the filter device. Simultaneously, the overflow hole 35 and the mounting hole 34 are opened to maintain the drainage function of the filter device, thus ensuring smooth drainage of the clothing treatment device.

[0083] In some embodiments, the overflow hole 35 is located below the first sealing ring 311, and the outer port of the overflow hole 35 is spaced apart from the peripheral sidewall of the receiving groove 10, so that the overflow hole 35 can communicate with the peripheral area of ​​the receiving groove 10.

[0084] Please see Figures 4 to 6 As shown, in some embodiments, the bottom of the end cap 3 is provided with a protruding isolation rib 36, which is annular in shape. A downward-facing water guide groove 360 ​​is formed inside the isolation rib 36, and this water guide groove 360 ​​is vertically connected to the filter tank 20. The outlet end of the water inlet channel 30 is connected to the water guide groove 360, thereby allowing water in the water inlet pipe 11 to be guided into the water guide groove 360 ​​through the water inlet channel 30, and then into the filter tank 20 for filtration.

[0085] In some embodiments, the bottom port of the mounting hole 34 is located at the top of the water guide channel 360, that is, the bottom port of the mounting hole 34 is connected to the water guide channel 360. When the filter tank 20 of the filter element 2 becomes clogged, the water level in the filter tank 20 rises and submerges the water guide channel 360, thereby increasing the water pressure at the bottom port of the mounting hole 34. When the water pressure at the bottom port of the mounting hole 34 is greater than the preset water pressure, the warning column 41 moves upward under the action of water pressure, opening the bottom port of the mounting hole 34 and the overflow hole 35. Water in the water guide channel 360 can then be introduced into the receiving groove 10 in the outer area of ​​the filter element 2 through the bottom port of the mounting hole 34 and the overflow hole 35, and then directly discharged to the outside of the housing 1 through the receiving groove 10.

[0086] Please see Figures 4 to 14 As shown, in some embodiments, the inner wall of the bottom end of the isolation rib 36 is provided with an internal thread (not shown in the figure), and the outer peripheral wall of the water distributor 6 is provided with an external thread (not shown in the figure). The water distributor 6 is threadedly connected to the isolation rib 36, thereby positioning the water distributor 6 and the water distribution trough 60 at the bottom port of the water guide trough 360. Water introduced through the water inlet channel 30 first enters the water guide trough 360, then enters the water distribution trough 60, and then enters the filter tank 20 through the water distribution port 61.

[0087] In some embodiments, a rotating handle 62 is provided on the bottom surface of the water distributor 6. The user can control the water distributor 6 to rotate within the water guide channel 360 by holding the rotating handle 62, thereby facilitating the installation or removal of the water distributor 6.

[0088] Please see Figures 4 to 6 As shown, in some embodiments, the outer peripheral wall of the bottom end of the isolation rib 36 is provided with a first external thread 361, and the inner side wall of the top end of the first filter element 2a is provided with a first internal thread (not shown in the figure) that mates with the first external thread 361. Through the engagement of the first internal thread and the first external thread 361, the first filter element 2a is threadedly fitted onto the bottom end of the isolation rib 36.

[0089] In some embodiments, a second external thread 37 is provided on the outer peripheral wall of the bottom end of the end cap 3, and the first external thread 361 and the second external thread 37 are arranged at an inward and outward interval. A second internal thread (not shown in the figure) is provided on the inner side wall of the top end of the second filter element 2b to mate with the second external thread 37. Through the engagement of the second internal thread and the second external thread 37, the second filter element 2b is threaded onto the bottom end of the end cap 3, and the second filter element 2b is spaced out and fitted onto the outer periphery of the first filter element 2a.

[0090] Please see Figures 4 to 6As shown, in some embodiments, the outer periphery of the second filter element 2b is spaced apart from the peripheral sidewall of the receiving groove 10, and an overflow area 101 is formed between the outer periphery of the second filter element 2b and the peripheral sidewall of the receiving groove 10. Therefore, when a blockage occurs in the filter groove 20, the water in the filter groove 20 and the water guide groove 360 ​​can flow out through the bottom port of the mounting hole 34 and the overflow hole 35, and be introduced into the overflow area 101, then into the receiving groove 10 below the filter element 2, and finally discharged outside the housing 1.

[0091] Please see Figures 4 to 14 As shown, in some embodiments, the warning module 4 further includes a telescopic tube 43, which extends vertically and is telescopically disposed within the mounting hole 34. A warning post 41 is disposed within the telescopic tube 43, with its lower end connected to the bottom end of the telescopic tube 43. A return spring 42 is disposed inside the telescopic tube 43 and sleeved on the warning post 41. The bottom end of the return spring 42 abuts against the bottom end of the telescopic tube 43, and the return spring 42 can drive the bottom end of the telescopic tube 43 and the bottom end of the warning post 41 to move downwards, thereby allowing the outer peripheral wall of the bottom end of the telescopic tube 43 to seal the bottom port of the mounting hole 34 and the overflow hole 35. Therefore, when blockage occurs in the filter tank 20, the water pressure at the bottom port of the mounting hole 34 causes the bottom end of the telescopic tube 43 to move upwards, thereby opening the bottom port of the mounting hole 34 and the overflow hole 35, allowing water in the filter tank 20 to drain through the overflow hole 35.

[0092] In some embodiments, the upper part of the telescopic tube 43 is corrugated, and the structure of the corrugated tube allows the telescopic tube 43 to be telescopically installed in the mounting hole 34. At the same time, the outer peripheral wall of the lower end of the telescopic tube 43 is a smooth structure, which allows the bottom port of the mounting hole 34 and the overflow hole 35 to be blocked by the outer peripheral wall of the lower end of the telescopic tube 43.

[0093] Please see Figures 4 to 14 As shown, in some embodiments, the warning module 4 further includes a plug 44, which covers the top port of the mounting hole 34. The plug 44 has a through hole (not shown) arranged opposite to the top of the warning post 41. The top of the warning post 41 movably passes through the through hole of the plug 44, thus protruding from the top surface of the plug 44. The top of the telescopic tube 43 is in contact with the bottom surface of the plug 44, so when the telescopic tube 43 extends or retracts, its bottom end can move up and down along the mounting hole 34. The top of the return spring 42 abuts against the bottom surface of the plug 44, so the bottom end of the return spring 42 can drive the bottom end of the telescopic tube 43 and the warning post 41 to move downwards along the mounting hole 34, thereby sealing the bottom port of the mounting hole 34 and the overflow hole 35.

[0094] In some embodiments, the end cap 3 has an upwardly extending mounting tube 341, and a mounting hole 34 is provided inside the mounting tube 341. A plug 44 is fitted onto the top end of the mounting tube 341, thereby allowing the plug 44 to cover the top end of the mounting hole 34.

[0095] Figure 17 yes Figure 11 A schematic diagram of the structure of the upper and middle cover 5. Figure 18 yes Figure 17 A sectional view.

[0096] Please see Figures 4 to 18 As shown, in some embodiments, the upper cover 5 is placed on the top surface of the end cover 3, and the upper cover 5 has a through hole 51 arranged opposite to the warning post 41. The top end of the warning post 41 passes through the mounting hole 34 and can be inserted into the through hole 51. When the filter tank 20 is not blocked, the top surface of the warning post 41 is flush with the top surface of the upper cover 5. When the filter tank 20 is blocked, the water pressure at the bottom port of the mounting hole 34 increases, and the warning post 41 can move upward under the action of water pressure and protrude through the through hole 51 onto the top surface of the upper cover 5, thereby making it easy for the user to observe and promptly remind the user to replace the filter element 2 or clean the filter tank 20.

[0097] In some embodiments, the bottom of the upper cover 5 is provided with a latching protrusion 52, and the peripheral sidewall of the top of the end cover 3 is provided with a latching slot 38. The upper cover 5 is latched onto the latching slot 38 by the latching protrusion 52, thereby making the upper cover 5 detachably cover the top of the end cover 3.

[0098] It should be noted that in some embodiments, the top cover 5 may also be integrally formed on the top area of ​​the end cover 3.

[0099] Please see Figure 1 and Figure 2 As shown, in some embodiments, an observation window 14 is provided on the outer wall of the housing 1, and the observation window 14 is located on the peripheral side wall of the receiving tank 10. The observation window 14 is made of transparent material, so the water level in the receiving tank 10 can be observed through the observation window 14, thereby determining whether the filter tank 20 is blocked or will be blocked, and reminding the user in time to replace the filter element 2 or clean the filter tank 20.

[0100] In some embodiments, the observation window 14 is elongated and extends vertically to facilitate the user's observation of the water level within the observation window 14.

[0101] Based on the structure of the filtration devices in the above embodiments, this invention also provides a clothing processing device, which can be a washing machine, a dryer, or a washer-dryer combo. The clothing processing device includes a housing, a drum, a drain pipe, and a filtration device.

[0102] The box is constructed as the outer shell of the clothing processing device.

[0103] The drum is located inside the box, and a clothes handling chamber is formed inside the drum, which can be used to wash or dry clothes.

[0104] The drain pipe is located outside the cylinder. One end of the drain pipe is connected to the inside of the cylinder, that is, one end of the drain pipe is connected to the clothing processing chamber, and the other end of the drain pipe extends outside the box, thereby draining the sewage in the clothing processing chamber out of the box.

[0105] The filter device is located outside the housing and is connected to the drain pipe. Specifically, the inlet pipe 11 of the filter device is connected to the drain pipe. Therefore, after the wastewater in the clothing processing chamber is discharged from the housing, it can enter the filter device for filtration and be discharged to the outside of the housing 1 through the outlet pipe 12, thereby filtering out microparticles in the wastewater, reducing the emission of microparticles into the environment, and thus reducing the damage of microparticles to the ecological environment.

[0106] It should be noted that when a blockage occurs, the warning post 41 of the filter device can protrude from the top surface of the filter device and be placed outside the housing so that the user can easily observe the protrusion of the warning post 41, thereby reminding the user to replace the filter element 2 or clean the filter tank 20 in time.

[0107] Figure 19 yes Figure 10 A schematic diagram of the structure of the latch 7. Figure 20 yes Figure 1 Another sectional view. Figure 21 yes Figure 20 A magnified view of a portion of the image.

[0108] Please see Figures 19 to 21 As shown, in some embodiments, the end cap 3 is provided with a latch 7, which is movably disposed between the top of the upper cover 5 and the top of the end cap 3. The outer peripheral wall of the end cap 3 is provided with a telescopic opening 39, and the peripheral side wall at the opening of the receiving groove 10 is recessed with a locking groove 15 arranged opposite to the telescopic opening 39. The first end of the latch 7 can pass through the telescopic opening 39 and engage in the locking groove 15, thereby locking the end cap 3 at the opening of the receiving groove 10. The second end of the latch 7 can protrude from the upper cover 5, thereby facilitating the user to press it. By pressing the end of the latch 7 protruding from the upper cover 5, the latch 7 can be moved into the telescopic opening 39, that is, moved away from the locking groove 15, so that the first end of the latch 7 is separated from the locking groove 15, thereby allowing the end cap 3 to be removed from the opening of the receiving groove 10.

[0109] In some embodiments, the second end of the latch 7 is provided with a pressing portion 71 that bends and extends toward its first end, and the pressing portion 71 is exposed outside the upper cover 5. By pressing the pressing portion 71 in a direction away from the first end, the latch 7 can be separated from the locking groove 15, and the first end of the latch 7 can be retracted into the telescopic opening 39.

[0110] In some embodiments, the second end of the latch 7 is disposed on the self-locking spring 8, which is disposed inside the end cover 3. The self-locking spring 8 abuts against the second end of the latch 7 to drive the latch 7 to move automatically toward its first end, thereby causing the first end of the latch 7 to extend out of the telescopic opening 39 and engage with the locking groove 15.

[0111] In some embodiments, two latches 7 are provided, arranged side-by-side within the end cap 3. Correspondingly, each side of the end cap 3 has a telescopic opening 39, and the peripheral sidewall of the receiving groove 10 has two locking grooves 15 arranged corresponding to the two telescopic openings 39. A self-locking spring 8 is disposed between the two latches 7, with one end of the self-locking spring 8 abutting against the second end of one latch 7 and the other end of the self-locking spring 8 abutting against the second end of the other latch 7, thereby causing the first ends of both latches 7 to automatically extend out of the corresponding telescopic openings 39 and engage with the corresponding locking grooves 15.

[0112] In some embodiments, the second ends of both latches 7 are provided with positioning portions 72, one end of the self-locking spring 8 is sleeved on the positioning portion 72 of one latch 7, and the other end of the self-locking spring 8 is sleeved on the positioning portion 72 of the other latch 7, thereby making the self-locking spring 8 stably fixed between the two latches 7.

[0113] In some embodiments, a stop portion 73 is provided on the left and right sides of the first end of the latch 7. When the latch 7 extends out of the telescopic opening 39 under the elastic force of the self-locking spring 8 and engages with the locking groove 15, the stop portion 73 can abut against the inner walls on both sides of the telescopic opening 39 to prevent the latch 7 from coming out of the telescopic opening 39.

[0114] In some embodiments, a transversely extending partition beam 53 is provided on the top surface of the upper cover 5. Each side wall of the partition beam 53 has a pressing opening 54, which communicates with the interior of the partition beam 53. The second end of the latch 7 extends into the partition beam 53, and the pressing portion 71 of the latch 7 protrudes through the pressing opening 54 and is exposed on the top surface of the upper cover 5. Therefore, by pressing the pressing portion 71 inwards towards the pressing opening 54, the latch 7 can be moved away from its first end, causing the first end of the latch 7 to separate from the locking groove 15.

[0115] In some embodiments, recessed relief grooves 55 are provided on both sides of the partition beam 53, and the relief grooves 55 are connected to the interior of the partition beam 53 through corresponding pressing ports 54. Therefore, the pressing parts 71 of the two latches 7 can extend out through the corresponding pressing ports 54 and be exposed in the corresponding relief grooves 55, so that the user can press them.

[0116] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
