[0002] Clothes processing equipment is a common household appliance. With the improvement of living standards, fully automatic clothes processing equipment has entered every household, because clothes processing equipment is simple and convenient to use, and can provide a lot of convenience for our fast-paced life. When working, clothes processing equipment can handle the hair attached to clothes to complete the cleaning of clothes. The fallen hair will accumulate inside the clothes processing equipment. However, at the moment when clothes processing equipment has entered the intelligent era, clothes processing equipment still needs to manually clean the hair accumulated inside itself. This cleaning method will increase the workload and reduce consumers' good impression of the experience of clothes processing equipment. In addition, if consumers do not clean the hair accumulated inside the clothes processing equipment in time or forget to clean it, the hair will breed bacteria in a humid and shaded environment, and even rot, which will eventually have a harmful effect on consumers' health. Summary of the invention

With the improvement of living standards, fully automatic clothes processing equipment has entered every household, because clothes processing equipment is simple and convenient to use, and can provide a lot of convenience for our fast-paced life. When working, clothes processing equipment can handle the hair attached to clothes to complete the cleaning of clothes. The fallen hair will accumulate inside the clothes processing equipment. However, at the moment when clothes processing equipment has entered the intelligent era, clothes processing equipment still needs to manually clean the hair accumulated inside itself. This cleaning method will increase the workload and reduce consumers' good impression of the experience of clothes processing equipment. In addition, if consumers do not clean the hair accumulated inside the clothes processing equipment in time or forget to clean it, the hair will breed bacteria in a humid and shaded environment, and even rot, which will eventually have a harmful effect on consumers' health.

[0047] Reference below Figure 1-Figure 4 A self-cleaning assembly according to an embodiment of the present invention is described.

[0048] The self-cleaning component 1 according to the present invention includes a shell and a filter device 12, a housing chamber 1112 is formed in the shell, and a first interface 113, a second interface 114 and a third interface 115 are respectively connected to the housing chamber 1112, the first interface 113 is suitable for connecting to the water outlet of the clothing processing device 101, the second interface 114 is suitable for connecting to the return water port 102 of the clothing processing device 101, and the third interface 115 is suitable for connecting to the sewage outlet; the filter device 12 can be rotatably accommodated in the housing chamber 1112, a filter chamber is formed in the filter device 12, and the filter chamber is connected to the second interface 114.

[0049] According to the self-cleaning component 1 of the present invention, a housing and a filter device 12 are constructed, and a housing chamber 1112 is defined inside the housing. The housing chamber 1112 can accommodate the filter device 12 so as to filter the sewage generated after the clothing processing device 101 works. Specifically, the housing is provided with a first interface 113, a second interface 114 and a third interface 115 connected to the housing chamber 1112, wherein the first interface 113 can be connected to the drain port of the clothing processing device 101 so as to guide the sewage generated by the clothing processing device 101 to the self-cleaning component 1, the second interface 114 can be connected to the return water port 102 of the clothing processing device 101 so as to guide the filtered water back to the clothing processing device 101 for recycling, and the third interface 115 can be connected to the sewage outlet so as to discharge the sewage in the housing when the self-cleaning component 1 performs self-cleaning work. In addition, the filter device 12 is rotatably arranged in the housing chamber 1112, and the rotating filter device 12 can improve the efficiency of filtering impurities such as hair scraps.

[0050] In some embodiments, the working process of the self-cleaning component 1 can be roughly understood as follows: when it is necessary to filter the sewage, the first interface 113 and the second interface 114 are opened, and the third interface 115 is closed. When the laundry processing device 101 discharges the sewage after cleaning the clothes into the self-cleaning component 1 through the pipeline, the filter device 12 can filter the sewage to remove impurities such as hair in the sewage, and the filtered water can flow from the filter cavity through the second interface 114 and then flow to the return water port 102 of the laundry processing device 101 for recycling. The setting of the second interface 114 improves the utilization rate of water by the laundry processing device 101. At this time, the hair and other impurities discharged by the filter device 12 will accumulate on the outer surface of the filter device 12. When the self-cleaning component 1 performs self-cleaning work, the first interface 113 and the third interface 115 are opened, and the second interface 114 is closed. The water flowing out of the first interface 113 can wash away the hair on the surface of the filter screen 122, and the sewage mixed with hair can flow to the sewage outlet through the second interface 114 for discharge to complete the cleaning process of the self-cleaning component 1. The self-cleaning component 1 is set to recycle the water used in the cleaning process while achieving self-cleaning of the hair debris accumulated in the clothing processing device 101, thereby improving the water utilization rate of the clothing processing device 101 and avoiding the breeding of bacteria caused by the accumulation of hair debris. In addition, the self-cleaning process does not require manual operation, thereby improving the user experience.

[0051] According to one embodiment of the present invention, the housing includes a housing body 111 and a cover body 112. The housing body 111 is formed with a receiving cavity 1112 and a first interface 113, a second interface 114 and a third interface 115. The housing body 111 is formed with a mounting port 1111. The cover body 112 is detachably disposed at the mounting port 1111, and the filter device 12 is rotatably connected to the cover body 112. Since the cleaning process of the self-cleaning component 1 is performed in the housing, the structure of the housing will affect the cleaning effect of the self-cleaning component 1.

[0052] Specifically, the shell is provided with a shell body 111 and a cover body 112, wherein a housing cavity 1112 and a first interface 113, a second interface 114 and a third interface 115 are formed in the shell body 111. The shell body 111 can serve as the basic structure of the entire self-cleaning component 1. The housing cavity 1112 and the first interface 113, the second interface 114 and the third interface 115 are processed on the shell body 111 to facilitate the assembly of various structures of the self-cleaning component 1. At the same time, a mounting port 1111 is also provided on the shell body 111, and the mounting port 1111 is connected to the housing cavity 1112. The setting of the mounting port 1111 facilitates the assembly of the filter device 12 in the self-cleaning component 1. It can be understood that: the filter device 12 can be directly assembled into the housing cavity 1112 through the mounting port 1111 during assembly, thereby improving the assembly efficiency. In addition, the cover 112 is detachably arranged on the installation opening 1111, and can seal the accommodating chamber 1112 after the filter device 12 is assembled into the accommodating chamber 1112 to prevent the filter device 12 from falling out of the accommodating chamber 1112, thereby improving the stability of the internal structure of the self-cleaning assembly 1 after assembly. At the same time, the filter device 12 is rotatably arranged on the cover 112 so that the cover 112 can serve as a support for the filter device 12 when it rotates, and the connection between the filter device 12 and the cover 112 improves the stability of the filter device 12 during rotation.

[0053] According to one embodiment of the present invention, the filter device 12 includes a bracket 121 and a filter screen 122, the bracket 121 is accommodated in the accommodating chamber 1112 and is rotatably connected to the cover body 112, and the end of the bracket 121 is provided with a filter outlet 123 connected to the second interface 114; the filter screen 122 is arranged on the bracket 121 to define the filter chamber. Since the filter device 12 is a structure used for cleaning in the self-cleaning component 1, the structure of the filter device 12 will affect the cleaning effect of the self-cleaning component 1. The filter device 12 is provided with a bracket 121 and a filter screen 122, and the bracket 121 can be understood as the supporting structure of the filter device 12 as a whole, the bracket 121 is accommodated in the accommodating chamber 1112 and is rotatably connected to the cover body 112, and the rotation of the bracket 121 itself can drive the entire filter device 12 to rotate, and the bracket 121 as the prime mover of the filter device 12 can make the filter device 12 rotate in the accommodating chamber 1112, ensuring that the filter device 12 can work normally.

[0054] The filter 122 is arranged on the bracket 121. The filter 122 is mainly used to filter sewage and define a filter cavity in the accommodating cavity 1112 so as to separate the sewage and the filtered water. At the same time, the bracket 121 is also provided with a filter outlet 123 at the end thereof which is connected with the second connection port. When the self-cleaning component 1 filters the sewage, the sewage transported by the clothing treatment device 101 is filtered by the filter device 12 and is in the filter cavity. The water in the filter cavity can flow back to the return water port 102 of the clothing treatment device 101 through the filter outlet 123 and the second connection port for recycling. It is worth noting that the filter 122 can be arranged on the inner circumference of the bracket 121 or on the outer circumference of the bracket 121. The scheme in which the filter 122 is arranged on the outer circumference of the bracket 121 is convenient for the assembly of the filter 122 but inconvenient for the fixing of the filter 122. The scheme in which the filter 122 is arranged on the inner circumference of the bracket 121 is convenient for the fixing of the filter 122 but inconvenient for the assembly of the filter 122. The specific setting scheme can be selected according to the actual processing and assembly situation.

[0055] According to one embodiment of the present invention, a plurality of blades 103 are formed on the outer periphery of the bracket 121 and are spaced apart in the circumferential direction. Since the rotation of the bracket 121 itself requires external force, the structure of the bracket 121 will affect the rotation of the bracket 121. Specifically, the filter device 12 is provided with a plurality of blades 103 spaced apart in the circumferential direction on the outer periphery of the bracket 121. When the first interface 113 is opened, the water entering from the first interface 113 can impact the bracket 121 and exert an external force on the blades 103 to drive the bracket 121 to rotate and then drive the entire filter device 12 to rotate. The filter device 12 can provide centrifugal force in the rotating state to make the hair on the filter screen 122 fall off to avoid the hair blocking the filter screen 122, thereby improving the filtering efficiency of the filter device 12 and facilitating the self-cleaning of the filter device 12. In addition, the scheme of driving the filter device 12 to rotate by water can also reduce the cost of setting up additional driving parts.

[0056] According to one embodiment of the present invention, the angle formed by the free ends of two adjacent blades 103 and the line connecting the rotating axis of the filter device 12 is a, and satisfies 60°≤a≤90°. Since the blades 103 are arranged on the periphery of the bracket 121 and the blades 103 can drive the bracket 121 to rotate under the impact of water, the structure of the blades 103 will affect the rotation of the bracket 121. Specifically, when the blades 103 are arranged on the filter device 12, the free ends of the two adjacent blades 103 form an angle a with the line connecting the rotating axis of the filter device 2, and satisfy 60°≤a≤90°. It can also be understood that the number of blades 103 on the periphery of the bracket 12 can be set to 4-6. Under this design scheme, the position setting scheme of the blades 103 can reduce the number and cost of processing the blades 103 while ensuring that the blades 103 are sufficient to drive the bracket to rotate normally.

[0057] According to one embodiment of the present invention, the angle between each blade 103 and the tangent line of the outer edge of the bracket 121 is b, and satisfies 40°≤b≤140°. Fig. 9 As shown, during processing, the blades 103 can be set at an angle. Specifically, the angle between each blade 103 and the tangent line of the outer edge of the bracket 121 is b, and b satisfies 40°≤b≤140°. The angle formed by the blade 103 and the tangent line of the outer edge of the bracket 121 avoids the flow direction of water impacting the filter device 12 being parallel to the extension direction of the blade 103, thereby increasing the impact force of the water flow on the blade 103, so as to accelerate the rotation rate of the filter device 12.

[0058] According to an embodiment of the present invention, the bracket 121 includes a first end plate 1211, a second end plate 1212 and a support rib 1213, wherein the first end plate 1211 is rotatably connected to the cover body 112; the second end plate 1212 is spaced apart from the first end plate 1211, and a filter outlet 123 is formed on the second end plate 1212; the two ends of the support rib 1213 are respectively connected to the first end plate 1211 and the second end plate 1212, and the support rib 1213 is configured to be a plurality of support ribs spaced apart along the outer periphery of the first end plate 1211. Since the bracket 121 is the foundation of the entire filter device 12, the structure of the bracket 121 will affect the overall structure of the filter device 12.

[0059] Specifically, the bracket 121 is provided with a first end plate 1211 and a second end plate 1212, the first end plate 1211 and the second end plate 1212 are arranged at intervals in the extension direction of the bracket 121, and the support ribs 1213 connect the first end plate 1211 with the second end plate 1212, wherein the support ribs 1213 are structured as a plurality of support ribs 1213, and the plurality of support ribs 1213 are arranged at intervals on the outer periphery of the first end plate 1211, and the plurality of support ribs 1213 can improve the connection strength between the first end plate 1211 and the second end plate 1212, thereby improving the stability of the bracket 121. At the same time, the first end plate 1211 is rotatably connected to the cover body 112 to ensure that the bracket 121 can maintain stable rotation on the cover body 112, and the second end plate 1212 can be processed with the filter outlet 123 in the above embodiment. The arrangement of the first end plate 1211 and the second end plate 1212 defines the length of the filter cavity and enables the filter cavity to be connected with the second interface 114. The bracket 121 constructs the skeleton of the filter device 12 by arranging the first end plate 1211 , the second end plate 1212 and the supporting ribs 1213 , so that the filter device 12 can rotate smoothly in the accommodating cavity 1112 , ensuring the normal use of the filter device 12 .

[0060] According to one embodiment of the present invention, a water retaining rib 124 is provided on the second end plate 1212, which is located at the periphery of the filter outlet 123 and extends toward the second interface 114. Since the water in the filter cavity flows back to the return water port 102 of the clothing processing device 101 through the filter outlet 123 and the second interface 114, the structure in which the filter outlet 123 is connected to the second interface 114 will affect the flow of water in the filter cavity. The self-cleaning component 1 is provided with a water retaining rib 124 on the second end plate 1212, and the water retaining rib 124 is arranged on the periphery of the filter outlet 123 and extends toward the direction of the second interface 114. When assembled, the water retaining rib 124 can cooperate with the second interface 114 to close the gap between the filter outlet 123 and the second interface 114. When the filtering function of the self-cleaning component 1 is activated, water from the clothing processing device 101 that flows into the accommodating chamber 1112 passes through the filter mesh 122 and then enters the filter chamber, and the water in the filter chamber flows to the second interface 114 through the filter outlet 123. At this time, the water retaining rib 124 can prevent the water in the filter chamber from contacting the sewage in the accommodating chamber 1112, thereby preventing the sewage from entering the second interface 114, thereby improving the water purification effect of the self-cleaning component 1.

[0061] According to one embodiment of the present invention, an annular rib 1214 is provided on the bracket 121, and the annular rib 1214 surrounds the outer periphery of the bracket 121 and connects multiple support ribs 1213. Since the filter device 12 rotates during operation, the structure of the bracket 121 will affect the rotation of the filter device 12. The self-cleaning component 1 is also provided with an annular rib 1214 on the bracket 121. The annular rib 1214 can be understood as a rib surrounding at least part of the outer peripheral surface of the bracket 121. During processing, the annular rib 1214 can connect multiple support ribs 1213 together, thereby improving the structural strength of the bracket 121 and ensuring the stability of the bracket 121 during rotation. At the same time, the annular rib 1214 surrounding the outer periphery of the bracket 121 can also provide support for the filter screen 122 in the circumferential direction, which is convenient for fixing the filter screen 122.

[0062] According to one embodiment of the present invention, a reinforcing connection portion 1215 is formed at the intersection of the annular rib 1214 and the support rib 1213, and the diameter of the reinforcing connection portion 1215 is greater than the width of the support rib 1213 and the width of the annular rib 1214. Since the filter screen 122 is arranged on the bracket 121, the structure of the bracket 121 will affect the assembly of the filter screen 122. The self-cleaning component 1 is also provided with a reinforcing connection portion 1215 at the connection between the annular rib 1214 and the support rib 1213, and the provision of the reinforcing connection portion 1215 improves the connection strength between the annular rib 1214 and the support rib 1213. Specifically, the reinforcing connection portion 1215 is configured as a circular ring, and the diameter of the reinforcing connection portion 1215 is greater than the width of the support rib 1213 and the width of the annular rib 1214, ensuring the stability of the connection between the support rib 1213 and the annular rib 1214. The bracket 121 can avoid the bracket 121 from breaking or deforming during the rotation process by providing the reinforcing connection part 1215, thereby improving the reliability of the filter device 12. In addition, the reinforcing connection part 1215 is configured as a circular ring, which can increase the contact area between the bracket 121 and the filter screen 122, thereby better supporting the filter screen 122. In actual processing, the reinforcing connection part 1215 can be processed with a through hole at the center position of its own circle, and the through hole can cooperate with fasteners or other components to enhance the stability of the filter screen 122 after assembly.

[0063] According to an embodiment of the present invention, the cover body 112 includes a bottom plate 1121 and an extension 1122, a pivot shaft 1124 is provided on the side of the bottom plate 1121 facing the accommodating cavity 1112, a matching ring sleeved on the outer periphery of the pivot shaft 1124 is provided on the first end plate 1211, and the matching ring rotates relative to the pivot shaft 1124; the extension 1122 is provided on the outer periphery of the bottom plate 1121 and extends away from the accommodating cavity 1112, and the outer peripheral surface of the extension 1122 is suitable for sealing connection with the inner wall of the installation opening 1111. Since the first end plate 1211 is rotatably provided on the cover body 112, the structure of the cover body 112 will affect the rotation of the first end plate 1211. The cover body 112 is constructed with a bottom plate 1121 and an extension 1122, wherein a pivot shaft 1124 is provided on the side of the bottom plate 1121 facing the accommodating chamber 1112, and a matching ring pivotally matched with the pivot shaft 1124 can be provided on the first end plate 1211. During assembly, the matching ring can be sleeved on the outer periphery of the pivot shaft 1124. The first end plate 1211 realizes a rotatable connection with the cover body 112 through the matching ring and the pivot shaft 1124. The arrangement of the matching ring and the pivot shaft 1124 can make the first end plate 1211 more stable during rotation. The extension 1122 is arranged on the outer periphery of the bottom plate 1121 and extends in a direction away from the accommodating chamber 1112. During assembly, the extension 1122 can cooperate with the inner wall of the installation opening 1111 to seal the installation opening 1111 to prevent water in the accommodating chamber 1112 from flowing out of the installation opening 1111. The provision of the extension portion 1122 improves the sealing performance of the cover body 112 to the accommodating cavity 1112 .

[0064] According to one embodiment of the present invention, a knob 1123 is provided on the side of the bottom plate 1121 away from the accommodating cavity 1112. Since the cover body 112 needs to be assembled into the installation opening 1111 to seal the accommodating cavity 1112, the structure of the cover body 112 will affect the assembly of the cover body 112. The cover body 112 is also provided with a knob 1123 on the bottom plate 1121, and the knob 1123 is arranged on the side of the bottom plate 1121 away from the accommodating cavity 1112. During assembly, the cover body 112 can be assembled into the installation opening 1111 by the knob 1123. The provision of the knob 1123 reduces the difficulty of assembling the cover body 112, making the assembly and disassembly of the cover body 112 more convenient. In addition, the extension portion 1122 extends in a direction away from the accommodating chamber 1112. Therefore, the extension portion 1122 and the bottom plate 1121 can cooperate to form a sink structure. At this time, the knob 1123 falls into the sink, and the extension portion 1122 can hide the knob 1123, preventing the knob 1123 from protruding from the shell and interfering with other structures of the clothing processing device 101, thereby improving the structural stability of the self-cleaning component 1.

[0065] According to one embodiment of the present invention, the outer surface of the extension 1122 is threadedly matched with the inner wall of the mounting port 1111. Since the cover body 112 needs to be assembled into the mounting port 1111 to seal the accommodating cavity 1112, the structure of the cover body 112 will affect the sealing effect between the cover body 112 and the mounting port 1111. The self-cleaning component 1 can be provided with a first thread on the outer peripheral surface of the extension 1122, and at the same time, the self-cleaning component 1 can also be provided with a second thread on the inner wall of the mounting port 1111. During assembly, the extension 1122 fits the inner wall of the mounting port 1111. At this time, the first thread and the second thread can be meshed with each other to achieve threaded matching between the extension 1122 and the inner wall of the mounting port 1111, thereby improving the sealing performance of the cover body 112 and the mounting port 1111 during assembly. In addition, a rubber sealing ring can be provided on the extension 1122 to further improve the sealing performance of the cover body 112 and the mounting port 1111.

[0066] According to one embodiment of the present invention, the first interface 113 and the third interface 115 extend radially along the rotation axis of the bracket 121, and the second interface 114 and the mounting port 1111 extend axially along the rotation axis of the bracket 121. Since the water in the self-cleaning component 1 needs to flow through the first interface 113, the second interface 114 and the third interface 115 when it is working, the structure of the first interface 113, the second interface 114 and the third interface 115 will affect the cleaning process of the self-cleaning component 1. The first interface 113 extends radially along the rotation axis of the bracket 121. When the sewage generated by the clothing processing device 101 enters the accommodating chamber 1112, it can flow radially to the filter device 12 under the guidance of the first interface 113. The radially arranged first interface 113 can make the sewage flow directly to the outer peripheral surface of the filter device 12. It can also be understood that the sewage at this time can directly impact the filter screen 122, thereby improving the filtering efficiency of the filter device 12. The second interface 114 extends in the axial direction of the rotating shaft of the bracket 121. When the filter device 12 is assembled in the accommodating chamber 1112, the second interface 114 can be directly opposite to and connected with the filter outlet 123. The position setting scheme of the second interface 114 can make the water in the filter chamber quickly flow back to the return water port 102 of the clothing processing device 101 through the second interface 114. The third interface 115 can extend in the radial direction of the rotating shaft of the bracket 121. The setting scheme of the third interface 115 makes the third interface 115 and the first interface 113 located on both sides of the filter device 12 respectively. When the self-cleaning component 1 cleans the filter device 12, the water used to wash the filter screen 122 can directly flow into the third interface 115, thereby improving the sewage discharge efficiency of the self-cleaning component 1. In addition, the mounting opening 1111 on the shell can extend in the axial direction of the rotating axis of the bracket 121. The mounting opening 1111 extending in the axial direction of the rotating axis of the bracket 121 facilitates the assembly of the filter device 12. Specifically, when the filter device 12 is assembled into the accommodating cavity 1112 through the mounting opening 1111, the extension direction of the bracket 121 and the first interface 113 can be orthogonal without additional position adjustment, thereby reducing the difficulty of assembling the filter device 12.

[0067] According to one embodiment of the present invention, the distance between the axis 104 of the first interface 113 and the rotation axis 105 of the filter device 12 is d, the radius of the filter device 12 is r, and 0<d<r is satisfied. Since the water entering the first interface 113 will impact the bracket 121, the position relationship between the first interface 113 and the bracket 121 will affect the rotation of the bracket 121. Specifically, when the bracket 121 is assembled into the accommodating cavity 1112, the distance between the axis 104 of the first interface 113 and the rotation axis 105 of the filter device 12 is d, the radius of the filter device 12 is r, 0<d<r, it can be understood that the projection of the axis 104 of the first interface 113 in the extension direction falls on one side of the rotation axis 105 of the filter device 12. The setting scheme of the positional relationship between the first interface 113 and the filter device 12 enables the water entering the accommodating chamber 1112 through the first interface 113 to impact the upper half of the filter device 12, thereby increasing the rotation speed of the filter device 12. Compared with the scheme in which the axis 104 of the first interface 113 and the rotating axis 105 of the filter device 12 are directly opposite, the staggered setting of the axis 104 of the first interface 113 and the rotating axis 105 of the filter device 12 can increase the rotation rate of the filter device 12, thereby improving the filtering effect and self-cleaning effect of the filter device 12.

[0068] According to one embodiment of the present invention, at least part of the edge of the first interface 113 is tangent to the outer peripheral wall of the filter device 12. When the filter device 12 is assembled into the accommodating chamber, at least part of the edge of the first interface 113 can be tangent to the outer peripheral wall of the filter device 12 in the extension direction, which can also be understood as that in the height direction, the upper vertex of the first interface 113 is at the same height as the upper vertex of the cross section of the filter device 12. The arrangement of the positional relationship between the first interface 113 and the filter device 12 allows all the water flowing into the accommodating chamber from the first interface to impact the filter device 12, thereby improving the driving ability of the water to rotate the filter device 12.

[0069] According to one embodiment of the present invention, the self-cleaning assembly 1 further includes a first pump housing 13 and a second pump housing 14, wherein the first pump housing 13 is disposed on the housing body 111 and a first cavity is formed in the first pump housing 13, the first cavity is communicated with the second interface 114, and a first pump outlet 132 communicated with the water return port 102 is provided in the radial direction of the first pump housing 13; the second pump housing 14 is disposed on the housing body 111 and a second cavity is formed in the second pump housing 14, the second cavity is communicated with the third interface 115, and a second pump outlet 142 communicated with the sewage outlet is provided in the radial direction of the second pump housing 14. Since the water flow of the self-cleaning assembly 1 needs to pass through the connecting pipeline between the housing and the clothing processing device 101, the structure of the housing will affect the connection of the pipeline.

[0070] Specifically, the self-cleaning component 1 is also provided with two pump shells on the housing, namely, a first pump shell 13 and a second pump shell 14, wherein the first pump shell 13 is provided on the housing body 111 and a first cavity is formed in the first pump shell 13, the first cavity can be connected with the second interface 114 so that the water in the filter cavity can enter the first cavity through the second interface 114, and a first pump outlet 132 connected with the return water port 102 can also be provided in the radial direction of the first pump shell 13. When the self-cleaning component 1 filters and cleans the sewage generated by the clothing processing device 101, the first interface 113 and the second interface 114 are opened, and the third interface 115 is closed, and the sewage generated by the clothing processing device 101 enters the accommodating chamber 1112 through the first interface 113, and the sewage in the accommodating chamber 1112 can flow into the filter cavity after being filtered by the filter device 12, and the water in the filter cavity can flow into the first cavity through the second interface 114, and the water entering the first cavity can flow back to the return water port 102 of the clothing processing device 101 under the guidance of the first pump outlet 132 for recycling. The setting of the first pump housing 13 enables the water in the filter chamber to be separated from the sewage in the receiving chamber 1112 during the flow route, thereby avoiding secondary pollution. At the same time, the setting of the first pump outlet 132 facilitates the connection between the return port 102 of the clothing processing device 101 and the second interface 114, and also facilitates the arrangement of the pipeline for conveying water. In addition, a first driving member 131 can also be set in the first pump housing 13. The first driving member 131 can be used to drive the water in the filter chamber to flow to the return port 102 of the clothing processing device 101, thereby avoiding the accumulation of filtered water in the filter chamber, thereby allowing the sewage in the receiving chamber 1112 to enter the filter chamber faster, thereby improving the water purification capacity of the self-cleaning component 1.

[0071] The second pump housing 14 can also be arranged on the housing body 111. Similar to the arrangement of the first pump housing 13, a second cavity can be defined inside the second pump housing 14. The second cavity can be communicated with the third interface 115 so that the sewage in the accommodating cavity 1112 can enter the second cavity through the third interface 115. A second pump outlet 142 communicated with the sewage outlet can be arranged in the radial direction of the second pump housing 14. When the self-cleaning component 1 cleans the filter 122, the first interface 113 and the third interface 115 are opened, and the second interface 114 is closed. The clothing processing device 101 can spray water toward the accommodating cavity 1112 through the first interface 113. The water sprayed from the first interface 113 can clean the impurities such as hair scraps on the surface of the filter 122. The hair scraps falling from the filter 122 are mixed with the water sprayed from the first interface 113 and flow to the second cavity. The mixture of water and hair scraps after entering the second cavity can flow to the sewage outlet through the second pump outlet 142 and be discharged. The design of the second pump housing 14 allows the hair debris on the filter device 12 to be discharged in time after it falls off, thereby preventing the hair debris from accumulating in the accommodating chamber 1112 and affecting the filtering effect of the filter device 12. Similarly, a second driving member 141 may be provided in the second pump housing 14 to drive the water in the accommodating chamber 1112 to flow quickly to the sewage outlet, thereby improving the self-cleaning ability of the self-cleaning component 1.

[0072] The laundry treating apparatus 101 according to the present invention is briefly described below.

[0073] The clothing treatment device 101 according to the present invention includes the self-cleaning component 1 in the above-mentioned embodiment. Since the clothing treatment device 101 according to the present invention is provided with the self-cleaning component 1 in the above-mentioned embodiment, during the use of the clothing treatment device 101, the sewage generated by the clothing treatment device 101 can flow into the self-cleaning component 1 and flow back to the return water port 102 of the clothing treatment device 101 after being filtered by the filter device 12 for secondary use, thereby improving the utilization rate of water by the clothing treatment device 101. In addition, the clothing treatment device 101 can also spray water toward the filter device 12 in the self-cleaning component 1 to clean the filter device 12, and the sewage generated after cleaning can be discharged through the sewage outlet, thereby improving the self-cleaning ability of the self-cleaning component 1, avoiding secondary contamination of the clothing treatment device 101, and the self-cleaning process does not require manual operation, thereby improving the user experience.

[0074] In some embodiments, the clothing processing device 101 may be a washing machine, a dryer, a washer-dryer, or the like.

[0075] In summary, the self-cleaning assembly 1 defines a housing 1112 by setting a shell, and the filter device 12 is assembled in the housing 1112 to filter the sewage generated by the clothing processing device 101. Specifically, the shell is constructed with a shell body 111 and a cover body 112. The housing body 111 defines a housing 1112 provided with a mounting port 1111. The filter device 12 can be directly assembled into the housing 1112 through the mounting port 1111, thereby improving the assembly efficiency of the filter device 12. The cover body 112 can seal the mounting port 1111 to prevent the water in the housing 1112 from flowing out of the mounting port 1111. At the same time, a pivot shaft 1124 is arranged on one side of the cover body 112 facing the housing 1112. The pivot shaft 1124 can cooperate with the matching ring on the bracket 121 of the filter device 12 to realize the rotatable connection between the filter device 12 and the cover body 112. The support 121 may also be provided with blades 103 to improve the driving ability of the water entering the first interface 113 to rotate the support 121. A knob 1123 may be provided on the side of the cover 112 away from the accommodating cavity 1112 for assembling the cover 112, and the provision of the knob 1123 reduces the difficulty of assembling the cover 112. The filter device 12 defines a filter cavity through the cooperation of the bracket 121 and the filter screen 122. At the same time, a filter outlet 123 is also provided on the bracket 121. The water filtered by the filter screen 122 can flow from the filter cavity through the filter outlet 123 and then flow into the first cavity defined by the first pump housing 13. The water in the first cavity flows back to the return water port 102 of the clothing treatment device 101 through the first pump outlet 132 under the drive of the first driving member 131; and the water in the accommodating cavity 1112 for cleaning the filter screen 122 can flow into the second cavity defined by the second pump housing 14 through the third interface 115. The water in the second cavity can flow to the sewage outlet and be discharged through the second pump outlet 142 under the drive of the second driving member 141. The setting of the self-cleaning component 1 can not only purify the sewage generated by the clothing treatment device 101 and recycle it, but also self-clean itself to avoid secondary pollution of the clothing treatment device 101. At the same time, no manual operation is required in the whole process, which improves the user experience.
