Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a clothing processing device. Background Technology

[0002] In recent years, the amount of plastic waste flowing into the ocean has been increasing, becoming a serious problem. About 40% of this is microplastics (smaller than 5 mm in size), and about 35% of these microplastics are believed to be caused by microfibers generated during the washing of clothing.

[0003] In existing washing machines, a drain filter is usually installed in the drain line so that the drain filter can recover microplastics in the wash water, thus recovering microplastics before the wash water is discharged.

[0004] However, because drain filters have a filter screen, microplastics and other impurities accumulate in the fine mesh structure of the screen during filtration, affecting the filtration capacity and even clogging the drain channels. Therefore, drain filters require frequent cleaning to maintain their filtration efficiency, which adds a burden to the user's cleaning and maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a clothing processing device that allows users to easily clean its filter.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: According to one aspect of the present invention, a clothing treatment device is provided, comprising: a drain filter connected to a drain pipe, the drain filter comprising: a housing having an internal accommodating cavity having an installation port, and an inlet and an outlet for connecting to the drain pipe on the side wall of the accommodating cavity; and a filter assembly detachably installed at the installation port, the filter assembly comprising: a filter cylinder housed within the accommodating cavity, the filter cylinder having a filter chamber communicating with the inlet, one end of the filter cylinder having an opening, and the peripheral side wall of the filter cylinder having... The filter chamber contains a filter section through which washing water flows to the receiving cavity. The filter section filters impurities from the washing water. A cleaning component is housed within the filter chamber. The cleaning component includes a cleaning disc and a sealing disc spaced apart. When the cleaning component is housed within the filter chamber, the sealing disc closes the opening. The cleaning disc is located on the side of the filter chamber away from the opening, and its periphery abuts against the inner wall of the filter chamber. The cleaning component moves out of the filter chamber from the opening along the axial direction of the filter cylinder, and the cleaning component can move the impurities out of the filter chamber.

[0007] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: The drain filter includes a shell and a filter assembly. A receiving cavity is provided inside the shell, and the receiving cavity has an installation port. An inlet and an outlet for connecting to a drain pipe are provided on the side wall of the receiving cavity. The filter assembly is detachably connected to the installation port and seals the installation port. The filter assembly includes a filter cylinder and a cleaning component. The filter cylinder is housed in the receiving cavity, and a filter chamber is provided inside the filter cylinder. The filter chamber communicates with the inlet, allowing washing water to flow into the filter chamber. Simultaneously, a filter section is provided on the peripheral side wall of the filter chamber, allowing washing water in the filter chamber to flow through the filter section into the receiving cavity, enabling the filter section to filter impurities in the washing water. Furthermore, an opening is provided at one end of the filter chamber, and the cleaning component is housed within the filter section. A cleaning disc and a sealing disc are spaced apart. The periphery of the cleaning disc abuts against the inner wall of the filter chamber. When the cleaning component is housed within the filter chamber, the cleaning disc abuts against the side of the filter chamber furthest from the opening, and the sealing disc closes the opening. Furthermore, the water inlet is positioned between the cleaning disc and the sealing disc, allowing the washing water to flow into the filter chamber and then into the receiving chamber. The filter section between the cleaning disc and the sealing disc filters the washing water, trapping impurities between them. When the cleaning component moves axially out of the filter chamber from the opening, the cleaning disc cleans the inner wall of the filter chamber in one pass, removing impurities and thus completing the cleaning of the filter chamber and filter section. This facilitates cleaning of the drain filter for the customer.

[0008] In one embodiment of this application, the peripheral wall of the filter cartridge includes a connected straight section and an arcuate section, the inner wall of the filter cavity is formed with a straight surface and an arcuate surface corresponding to the straight section and the arcuate section, and the periphery of the cleaning member abuts against the straight surface and the arcuate surface.

[0009] The filter cartridge features a combination of straight and curved sections on its peripheral wall. This design creates a larger space between the straight section and the inner wall of the receiving cavity, allowing for the holding of more washing water and increasing its flow space and rate. Simultaneously, the filter cavity contains straight and curved surfaces corresponding to the straight and curved sections. The periphery of the cleaning component abuts against both these surfaces, effectively limiting its movement and preventing rotation relative to the filter cartridge around its axis.

[0010] In one embodiment of this application, a water inlet hole is provided on the arc segment, the water inlet hole is located on the side away from the opening of the filter chamber, and the water inlet hole is provided corresponding to the water inlet.

[0011] The curved section has a water inlet hole located on the side away from the opening. This allows the washing water to flow from the filtration section into the receiving cavity after entering the filter chamber, thus completing the filtration of the washing water. Simultaneously, the water inlet hole on the curved section allows the washing water to flow from the filtration section on the straight section into the receiving cavity, increasing the flow rate of the washing water. Furthermore, the water inlet hole is located upstream of the opening in the direction of washing water flow, ensuring that the filtration section on the inner wall of the filter chamber can effectively filter the washing water after it flows into the filter chamber, thereby improving the filtration efficiency of the filter chamber.

[0012] In one embodiment of this application, a rubber ring is provided around the periphery of the cleaning disc.

[0013] The cleaning disc is fitted with a rubber ring around its periphery, which increases the friction between the periphery of the cleaning disc and the inner wall of the filter chamber, thereby enhancing the cleaning effect of the cleaning disc on the filter section.

[0014] In one embodiment of this application, the cleaning component further includes a connecting rod connected between the cleaning disc and the sealing disc, wherein the radial dimension of the connecting rod is smaller than the radial dimension of the cleaning disc.

[0015] The radial dimension of the connecting rod is smaller than that of the cleaning disc, so that the washing water entering from the water inlet can flow into the filter chamber, avoiding the connecting rod being too large and occupying too much space in the filter chamber, causing passage blockage.

[0016] In one embodiment of this application, a sealing portion is formed at the end of the filter cartridge away from the opening, and the sealing portion is capable of abutting against and sealing the mounting port.

[0017] The filter cartridge has a sealing part at the end away from the opening. When the filter cartridge is placed in the receiving cavity, the sealing part can seal the installation port to prevent the washing water in the receiving cavity from leaking out of the receiving cavity from the installation port.

[0018] In one embodiment of this application, the garment processing device further includes a locking member detachably connected to the mounting port and capable of abutting against the filter cartridge to limit the filter assembly within the receiving cavity.

[0019] The locking element is detachably connected to the mounting port, allowing for easy opening and closing of the mounting port. When connected to the mounting port, the locking element abuts against the filter cartridge, thus confining the filter cartridge and cleaning component within the receiving cavity and preventing the filter assembly from automatically detaching from the receiving cavity during use.

[0020] In one embodiment of this application, a locking groove is provided on the outer peripheral wall of the locking member, and a locking protrusion is provided on the inner wall of the mounting port. The locking protrusion is adapted to the locking groove. When the locking member rotates relative to the housing, the locking protrusion can be locked in the locking groove to restrict the axial movement of the locking member relative to the housing.

[0021] The locking component has a locking groove and a locking protrusion inside the mounting opening. The locking groove and the locking protrusion cooperate with each other. When the locking component rotates relative to the housing, the locking protrusion can be engaged in the locking groove to lock the locking component in the mounting opening; or, the locking protrusion can disengage from the locking groove to unlock the locking component from the mounting opening.

[0022] In one embodiment of this application, the locking member has a connecting portion protruding on the side facing the filter cylinder, and the connecting portion has an abutting protrusion protruding circumferentially. The filter cylinder has a connecting groove on the side away from the opening, and a limiting protrusion protrudes on the inner peripheral wall of the connecting groove. The connecting portion can extend into the connecting groove, and the limiting protrusion can abut against the abutting protrusion to restrict the locking member from moving axially relative to the filter cylinder. The locking member can rotate relative to the filter cylinder.

[0023] The locking component has a connecting part with an abutting protrusion, and the filter cartridge has a connecting groove with a limiting protrusion. When the connecting part extends into the connecting groove, the abutting protrusion abuts against the limiting protrusion to restrict the locking component from moving axially relative to the filter cartridge, thereby allowing the locking component to drive the filter assembly in and out of the receiving cavity. Simultaneously, the locking component can rotate relative to the filter cartridge. When the locking component is locked into or unlocked from the mounting port, the filter cartridge remains connected to the locking component, facilitating the movement of the filter cartridge by the locking component.

[0024] In one embodiment of this application, the garment processing device further includes a washing tub and a drain pipe. The housing forms the outer shell of the garment processing device. The washing tub and the drain pipe are installed inside the housing. One end of the drain pipe is connected to the washing tub, and the other end extends out of the housing for discharging washing water from the washing tub. The drain pipe is connected to a drain filter, which is located inside the housing.

[0025] The washing tub and drain pipe are both installed inside the cabinet, and the drain filter is connected to the drain pipe and also located inside the cabinet. Therefore, no space needs to be reserved for installing the drain filter when installing the washing machine, making installation convenient. At the same time, the drain filter, connected to the drain pipe, filters the washing water discharged from the tub, intercepting impurities such as microplastics, ensuring that the discharged washing water meets requirements and preventing environmental pollution from impurities in the washing water.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] In existing washing machines, a drain filter is typically installed in the drain line to recover microplastics from the wash water before it is discharged. However, because the drain filter has a filter screen, microplastics and other impurities accumulate in the fine mesh structure during filtration, affecting the filtration capacity and even clogging the drain channel. Therefore, the drain filter requires frequent cleaning to maintain its filtration efficiency, which places a burden on the user in terms of cleaning and maintenance. Therefore, a clothing treatment device is proposed to solve the above problems.

[0042] The solution is further illustrated by the following examples: Figure 1 This is a schematic diagram of a clothing processing device according to an embodiment of the present invention. Figure 2 yes Figure 1 A schematic diagram of the drain filter of the garment processing device. Figure 3 yes Figure 2 An exploded view of the drainage filter. Figure 4 yes Figure 2 A cross-sectional view of the drainage filter.

[0043] Please see Figure 1 The garment processing device of this embodiment can be used to wash garments. It can also be used to wash other items to be washed, such as blankets, duvet covers, and sheets. Specifically, the garment processing device can be a top-loading washing machine, a front-loading washing machine, a dryer, a washer-dryer combo, or other garment processing devices.

[0044] In some embodiments, the garment handling apparatus may include a housing 10, a washing tub 11, a drain pipe 12, and a drain filter 13.

[0045] The housing 10 can form the outer shell of the clothing handling device, and the interior of the housing 10 can have an installation space. In some embodiments, the housing 10 can be provided with a loading port for loading or unloading clothing. The loading port can also be provided with a door to cover it.

[0046] In some embodiments, the washing tub 11 is installed inside the housing 10 for holding clothes. The washing tub 11 can rotate relative to the housing 10 to rotate the items to be washed and complete the washing process. The washing tub 11 may include an inner tub and an outer tub, with the inner tub fitted inside the outer tub to meet washing needs.

[0047] In some embodiments, one end of the drain pipe 12 is connected to the washing tub 11, and the other end extends out of the housing 10 to discharge the washing water in the washing tub 11.

[0048] In some embodiments, the drain filter 13 may be connected to the drain pipe 12 and located inside the housing 10. The drain filter 13 can be used to filter impurities in the washing water.

[0049] It should be noted that the drain filter 13 is located inside the housing 10. When installing the washing machine, there is no need to reserve space for installing the drain filter 13, which makes the installation of the washing machine more convenient.

[0050] Meanwhile, in some embodiments, the drain filter 13 may be partially connected to the outside of the housing 10, allowing the user to directly operate the drain filter 13 to clean it.

[0051] In addition, the drain filter 13 is connected to the drain pipe 12 and can filter the washing water discharged from the washing tub 11, that is, intercept impurities such as microplastics in the washing water, ensuring that the discharge of washing water meets the requirements and avoiding environmental pollution caused by impurities in the washing water.

[0052] See Figure 2 and Figure 3 In some embodiments, the drain filter 13 may include a housing 20 and a filter assembly 30.

[0053] The housing 20 has an internal cavity 21, and one end of the cavity 21 has a through mounting port 22, allowing the filter assembly 30 to pass through the mounting port 22 and be housed within the cavity 21. The cavity 21 also has an inlet 23 and an outlet 24 on its side wall, which are connected to the drain pipe 12, allowing the washing water from the washing tub 11 to flow through the cavity 21 and the filter assembly 30.

[0054] In some embodiments, the filter assembly 30 is detachably installed at the mounting port 22 to facilitate placing the filter assembly 30 in the receiving cavity 21 or removing the filter assembly 30 from the receiving cavity 21.

[0055] It should be noted that when the filter assembly 30 is placed in the receiving cavity 21, the end of the filter assembly 30 can be sealed at the mounting port 22 to prevent the washing water in the receiving cavity 21 from leaking out of the housing 20 through the mounting port 22.

[0056] In some embodiments, the filter assembly 30 may include a filter cartridge 31 and a cleaning member 32. The filter cartridge 31 may be housed within a receiving cavity 21, and the filter cartridge 31 has a filter chamber 311 communicating with the water inlet 23, allowing washing water to flow into the filter chamber 311. Furthermore, a filter section 313 is provided on the peripheral sidewall of the filter cartridge 31, allowing the washing water in the filter chamber 311 to flow through the filter section 313 into the receiving cavity 21.

[0057] See Figure 4 In some embodiments, when the filter cartridge 31 is housed within the receiving cavity 21, a gap is formed between the outer wall of the filter cartridge 31 and the inner wall of the receiving cavity 21, allowing the washing water in the filter cavity 311 to flow into the space between the outer wall of the filter cartridge 31 and the inner wall of the receiving cavity 21 after passing through the filter section 313. That is, the washing water flows from the drain pipe 12 through the inlet 23 into the filter cavity 311, then through the filter section 313 into the receiving cavity 21, and finally flows from the outlet 24 back into the drain pipe 12.

[0058] At the same time, the filter section 313 can filter impurities in the washing water, so that impurities such as microplastics in the washing water are intercepted on the filter section 313, that is, intercepted in the filter chamber 311.

[0059] It should be noted that, in some embodiments, the filter section 313 has filter mesh openings for filtering impurities in the washing water. In some embodiments, the filter mesh openings can be directly formed on the side wall of the filter cylinder 31, that is, through holes are directly opened on the side wall of the filter cylinder 31 to form filter mesh openings.

[0060] In some embodiments, the filter section 313 may be provided with a metal filter screen, and the metal filter screen is fixed on the side wall of the filter cylinder 31 so that the metal filter screen can perform filtration.

[0061] In some embodiments, the filter cylinder 31 has an opening 312 at one end, allowing the cleaning member 32 to be received within the filter cavity 311 through the opening 312. Simultaneously, the periphery of the cleaning member 32 abuts against the inner wall of the filter cavity 311. When the cleaning member 32 moves axially relative to the filter cylinder 31, its periphery can scrape and clean the filter section 313. Furthermore, when the cleaning member 32 moves out of the filter cavity 311 from the opening 312 along the axial direction of the filter cylinder 31, it can carry impurities out of the filter cavity 311. Thus, while cleaning the filter section 313, the cleaning member 32 can also remove impurities from the filter cavity 311, facilitating cleaning of the drain filter 13 by the user.

[0062] It should be noted that, in some embodiments, when the cleaning member 32 is housed in the filter chamber 311, the cleaning member 32 can seal the opening 312 of the filter chamber 311 to prevent the washing water in the filter chamber 311 from leaking out of the filter chamber 311 through the opening 312.

[0063] Figure 5 yes Figure 2 A magnified view of a portion of the drainage filter. Figure 6 yes Figure 2 A schematic diagram of the locking mechanism and filter assembly of the drain filter. Figure 7 yes Figure 6 A cross-sectional view of the locking and filtering components. Figure 8 yes Figure 2 A schematic diagram of the locking mechanism of the drain filter.

[0064] See Figure 5 and Figure 6 In some embodiments, a sealing portion 33 may be formed on the filter cartridge 31, located at the end of the filter cartridge 31 away from the opening 312. When the filter cartridge 31 is housed in the receiving cavity 21, the sealing portion 33 can abut against and seal the mounting port 22. Specifically, when the filter cartridge 31 is housed in the receiving cavity 21, the sealing portion 33 can seal the mounting port 22 to prevent the washing water in the receiving cavity 21 from leaking out of the receiving cavity 21 from the mounting port 22, that is, to prevent the washing water in the receiving cavity 21 from leaking out of the housing 20.

[0065] It should be noted that in some embodiments, the sealing part 33 may also be provided at the end of the filter cylinder 31 where the opening 312 is provided, that is, the sealing part 33 and the opening 312 are located on the same end of the filter cylinder 31 in the axial direction, and the sealing part 33 can close the mounting port 22 when the filter cylinder 31 is housed in the housing cavity 21.

[0066] See Figure 3 and Figure 5 In some embodiments, the drain filter 13 may also include a locking member 50. The locking member 50 is detachably connected to the mounting port 22 and can abut against the filter cartridge 31 to limit the filter assembly 30 within the receiving cavity 21.

[0067] Specifically, the locking member 50 can be engaged at the mounting port 22, allowing the locking member 50 to be connected to the housing 20 and closing the mounting port 22. Simultaneously, the locking member 50 can be removed from the housing 20, thereby opening the mounting port 22.

[0068] Furthermore, when the locking member 50 is connected to the mounting port 22, the locking member 50 can abut against the filter cartridge 31, thereby limiting the filter cartridge 31 and the cleaning member 32 within the receiving cavity 21, preventing the filter assembly 30 from automatically detaching from the receiving cavity 21 during use.

[0069] See Figure 3 , Figure 5 and Figure 8 In some embodiments, a locking groove 51 may be provided on the outer peripheral wall of the locking member 50, and two locking grooves 51 are provided, and the two locking grooves 51 are centrally symmetrically arranged on the outer peripheral wall of the locking member 50.

[0070] Meanwhile, the inner wall of the mounting port 22 is provided with a locking protrusion 221, which is adapted to the locking groove 51. When the locking member 50 rotates relative to the housing 20, the locking protrusion 221 can be locked in the locking groove 51 to restrict the locking member 50 from moving axially relative to the housing 20.

[0071] Specifically, when the locking member 50 rotates relative to the housing 20 about the central axis of the housing 20, the locking protrusion 221 can be engaged in the locking groove 51, so that the locking member 50 is locked in the mounting port 22; or the locking protrusion 221 can be disengaged from the locking groove 51, thereby unlocking the locking member 50 from the mounting port 22.

[0072] In some embodiments, the locking member 50 and the mounting port 22 can be engaged by a spring clip and a locking block, or they can be connected by threads, so that the locking member 50 can be detachably connected to the mounting port 22.

[0073] See Figure 8 In some embodiments, the locking member 50 may be provided with a connecting portion 52, and the connecting portion 52 protrudes on the side of the locking member 50 facing the filter cylinder 31, and the connecting portion 52 is provided with an abutting protrusion 521 in the radial direction in the circumferential direction.

[0074] See Figure 3 In some embodiments, the filter cylinder 31 may be provided with a connecting groove 331, and the connecting groove 331 is provided on the side of the filter cylinder 31 away from the outlet 312. A limiting protrusion 332 is provided on the inner peripheral wall of the connecting groove 331 in the radial direction.

[0075] See Figure 5 and Figure 7 In some embodiments, the connecting portion 52 can extend into the connecting groove 331, and the limiting protrusion 332 can abut against the abutting protrusion 521, thereby restricting the locking member 50 from moving axially relative to the filter cylinder 31, so that the filter cylinder 31 can move with the locking member 50, and thus the filter assembly 30 can move with the locking member 50.

[0076] Meanwhile, the locking member 50 can rotate relative to the filter cylinder 31. When the locking member 50 is locked into the mounting port 22 or unlocked from the mounting port 22, the filter cylinder 31 can remain connected to the locking member 50, which facilitates the locking member 50 to move the filter assembly 30, so that the locking member 50 moves the filter assembly 30 out of the receiving cavity 21, or moves the locking member 50 moves the filter assembly 30 into the receiving cavity 21.

[0077] In some embodiments, the locking member 50 can be directly connected to the cleaning member 32, thereby causing the cleaning member 32 to move relative to the filter cylinder 31 and the housing 20, so that the locking member 50 can drive the cleaning member 32 out of the filter chamber 311.

[0078] Specifically, when the sealing part 33 and the opening 312 are located on the same end of the filter cylinder 31 in the axial direction, the locking member 50 can be directly connected to the cleaning member 32, and the two can rotate relative to each other, so that the locking member 50 can drive the cleaning member 32 to move relative to the filter cylinder 31, thereby enabling the cleaning member 32 to complete the cleaning of the filter part 313 and carry the impurities filtered in the filter chamber 311 out of the filter chamber 311.

[0079] Figure 9 yes Figure 2 A schematic diagram of the filter components of a drainage filter. Figure 10 yes Figure 2 Another schematic diagram of the filter assembly of the drain filter. Figure 11 yes Figure 2 A schematic diagram of the cleaning components of the drain filter.

[0080] See Figure 9 and Figure 10 In some embodiments, the peripheral wall of the filter cartridge 31 may include a connected straight section 314 and an arc-shaped section 315, so that the outer peripheral wall of the filter cartridge 31 forms a non-cylindrical structure. When the filter cartridge 31 is housed in the receiving cavity 21, a large space is formed between the straight section 314 and the inner wall of the receiving cavity 21, which allows the space between the straight section and the inner wall of the receiving cavity to hold more washing water, thereby increasing the flow space of the washing water and improving the flow rate of the washing water.

[0081] In some embodiments, the inner wall of the filter cavity 311 may be formed with a straight surface 316 corresponding to the straight section 314 and an arcuate surface 317 corresponding to the arcuate section 315. The straight surface 316 and the arcuate surface 317 are connected to form the inner wall of the filter cavity 311.

[0082] In some embodiments, the periphery of the cleaning member 32 abuts against both the flat surface 316 and the arcuate surface 317, so that the flat surface 316 and the arcuate surface 317 can simultaneously limit the cleaning member 32 and prevent the cleaning member 32 from rotating relative to the filter cylinder 31 around its own axis.

[0083] It should be noted that, in some embodiments, both the straight section 314 and the arc-shaped section 315 are provided with filter portions 313 to increase the area of ​​the filter portions 313 on the inner wall of the filter cavity 311, thereby increasing the filtration capacity of the filter cartridge 31.

[0084] like Figure 10As shown, in some embodiments, an inlet hole 318 may be provided on the arc segment 315. The inlet hole 318 is located on the side away from the opening 312 of the filter chamber 311, and the inlet hole 318 is provided corresponding to the inlet 23, so that the washing water in the drain pipe 12 flows into the filter chamber 311 along the inlet 23 and the inlet hole 318.

[0085] The arc-shaped section 315 has a water inlet hole 318, which is located on the side away from the opening 312. This allows the washing water to flow from the filter section 313 on the side wall of the filter chamber 311 to the receiving chamber 21 after entering the filter chamber 311, thereby completing the filtration of the washing water.

[0086] Meanwhile, a water inlet 318 is provided on the arc-shaped section 315, allowing washing water to flow from the filter section 313 on the straight section 314 into the receiving cavity 21, thereby increasing the flow rate of the washing water. Furthermore, the water inlet 318 is located on the side away from the opening 312, upstream of the opening 312 in the direction of washing water flow. This allows the filter section 313 on the inner wall of the filter cavity 311 to filter the washing water after it flows into the filter cavity 311, thus improving the filtration efficiency of the filter cavity 311.

[0087] In some embodiments, the water inlet 318 may be provided on the straight section 314 and located on the side close to the opening 312, so that the washing water in the drain pipe 12 can flow along the water inlet 23 and the water inlet 318 into the filter chamber 311.

[0088] Figure 11 yes Figure 2 A schematic diagram of the cleaning components of the drain filter.

[0089] See Figure 7 and Figure 11 In some embodiments, the cleaning component 32 may include a cleaning disc 321 and a sealing disc 322, and the cleaning disc 321 and the sealing disc 322 are spaced apart.

[0090] Specifically, when the cleaning component 32 is housed within the filter chamber 311, the sealing disc 322 can close the opening 312, and the cleaning disc 321 is located on the side of the filter chamber 311 away from the opening 312. The water inlet 318 corresponds to the space between the cleaning disc 321 and the sealing disc 322, allowing the filter section 313 located between the cleaning disc 321 and the sealing disc 322 to filter the washing water as it flows into the filter chamber 311 and into the receiving chamber 21, thus trapping impurities between the cleaning disc 321 and the sealing disc 322. When the cleaning component 32 moves axially out of the filter chamber 311, the cleaning disc 321 can clean the filter section 313 on the inner wall of the filter chamber 311 in one pass, removing impurities from the filter chamber 311, thereby completing the cleaning of the filter chamber 311 and the filter section 313, facilitating cleaning of the drain filter 13 by the customer.

[0091] It should be noted that, in some embodiments, the axial projections of the cleaning disc 321 and the sealing disc 322 are the same as the axial projections of the inner wall of the filter cylinder 31, thereby enabling the flat surface 316 in the filter cavity 311 to fit against the peripheral walls of the cleaning disc 321 and the sealing disc 322, thereby enabling the flat surface 316 to guide the movement of the cleaning component 32 and restrict the cleaning component 32 from rotating relative to the filter cylinder 31 around its axis.

[0092] In some embodiments, a rubber ring 324 may be fitted around the periphery of the cleaning disc 321, and the rubber ring 324 may be configured as a flexible rubber ring to increase the friction between the cleaning disc 321 and the inner wall of the filter chamber 311, thereby increasing the cleaning effect of the cleaning disc 321 on the filter section 313.

[0093] In some embodiments, the cleaning disc 321 may be configured as a plastic disc, a plastic plate, or an integral rubber disc, so that the cleaning disc 321 can clean the filter chamber 311.

[0094] See Figure 10 and Figure 11 In some embodiments, the cleaning component 32 may further include a connecting rod 323. The connecting rod 323 connects the cleaning disc 321 and the sealing disc 322, and the radial dimension of the connecting rod 323 is smaller than the radial dimension of the cleaning disc 321. This ensures that after the cleaning component 32 is housed in the filter chamber 311, there is still space between the inner wall of the filter chamber 311 and the connecting rod 323. This allows the washing water entering through the water inlet 318 to flow into the filter chamber 311, preventing the connecting rod 323 from occupying too much space in the filter chamber 311 due to its excessively large radial dimension, thus avoiding blockage of the passage.

[0095] In some embodiments, a handle 325 is provided on the side of the sealing disc 322 opposite to the connecting rod 323. The handle 325 is used for the user to pull the cleaning component 32 to move the cleaning component 32 out of the filter chamber 311, thereby completing the cleaning of the filter chamber 311 and the filter section 313.

[0096] Furthermore, in some embodiments, the opening direction of the mounting port 22 of the housing 20 is opposite to the opening direction of the filter cylinder 31. Therefore, when the drain filter 13 needs to be cleaned, firstly, the locking member 50 is unlocked, and the locking member 50 and the filter assembly 30 are moved out of the receiving cavity 21. Then, the cleaning member 32 is manually pulled out of the filter cavity 311 from the side of the filter cylinder 31 opposite to the locking member 50, so that the cleaning disc 321 of the cleaning member 32 cleans the filter cavity 311 and carries away impurities from the filter cavity 311. After cleaning, the cleaning member 32 is put back into the filter cavity 311, and the locking member 50 and the filter assembly 30 are put back into the receiving cavity 21. The locking member 50 is then locked onto the housing 20, so that the drain filter 13 can continue to filter the washing water.

[0097] In summary, the drain filter 13 includes a housing 20 and a filter assembly 30. The housing 20 contains a receiving cavity 21 with an installation port 22. The side wall of the receiving cavity 21 has an inlet 23 and an outlet 24 that connect to the drain pipe 12. The filter assembly 30 is detachably connected to the installation port 22 and seals the installation port 22. The filter assembly 30 includes a filter cylinder 31 and a cleaning component 32. The filter cylinder 31 is housed within the receiving cavity 21 and contains a filter chamber 311. The filter chamber 311 communicates with the inlet 23, allowing washing water to flow into the filter chamber 311. Simultaneously, a filter section 313 is provided on the peripheral side wall of the filter chamber 311, allowing washing water in the filter chamber 311 to flow through the filter section 313 into the receiving cavity 21, enabling the filter section 313 to filter impurities in the washing water. In addition, an opening 312 is provided at one end of the filter chamber 311, and the cleaning member 32 is housed in the filter section 313. The periphery of the cleaning member 32 abuts against the inner wall of the filter chamber 311. When the cleaning member 32 moves out of the filter chamber 311 from the opening 312 along the axial direction of the filter cylinder 31, the cleaning member 32 can carry impurities out of the filter chamber 311. Thus, while cleaning the filter section 313, the impurities in the filter chamber 311 can also be carried out, which makes it convenient for the user to clean the drain filter 13.
