[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 process 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 enters 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' experience of clothes processing equipment. 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. In addition, in existing self-cleaning equipment, due to insufficient filtering capacity, the water flowing back into the clothes processing equipment may form secondary pollution, affecting the user experience. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a filter device. According to the filter device of the present invention, a first filter element is rotatably arranged in a housing, and the filter device is switched between a filtering state and a self-cleaning state by rotating the first filter element, thereby realizing the filtering function and self-cleaning function of the filter device and improving the user experience.

[0008] According to the filtering device of the present invention, a shell and a first filter element are provided, and a first accommodating chamber is formed in the shell, and the first accommodating chamber can be used to accommodate the first filter element. During assembly, the first filter element can be movably arranged in the first accommodating chamber so that the filtering device can filter the water entering the first accommodating chamber. Specifically, a first interface and a second interface are formed on the shell, and the first interface can be understood as the water inlet of the filtering device. During assembly, the first interface can be connected to the water outlet of the clothing processing equipment so that the sewage generated by the clothing processing equipment can flow into the filtering device for filtration; the second interface can be understood as the water outlet of the filtering device. During assembly, the second interface can be connected to the sewage outlet or other drainage structure of the clothing processing equipment so that the filtered water can be discharged from the filtering device through the second interface.

[0009] The filter device can be divided into a filtering state and a self-cleaning state when working. The corresponding state can be selected according to needs when using the filter device.

[0024] According to one embodiment of the present invention, in the filtering state, the projections of the third interface and the second interface on the first filter element are respectively located on both sides of the rotating axis; in the self-cleaning state, the projections of the first interface and the second interface on the first filter element are respectively located on both sides of the rotating axis.

[0025] According to an embodiment of the present invention, one-way valves are provided in the first interface and the third interface.

[0026] The filter assembly according to the present invention is briefly described below.

[0027] The filter assembly according to the present invention comprises the filter device and the separation device in the above embodiment, wherein the separation device is formed with a fourth interface, a fifth interface and a sixth interface, the fourth interface is communicated with the water outlet of the clothing processing device, the fifth interface is communicated with the water return port of the clothing processing device, and the sixth interface is communicated with the first interface. Since the filter assembly according to the present invention is provided with the filter device in the above embodiment, the water generated by the clothing processing device can enter the separation device through the fourth interface, and the separation device can process the water entering the separation device itself to separate clean water and water mixed with hair debris. Under the action of the separation device, the clean water flows back to the water return port of the clothing processing device through the fifth interface for secondary use, and the water mixed with impurities such as hair debris can flow to the first interface through the sixth interface and flow into the filter device for filtration. The filter device can filter the water introduced by the sixth interface through the first filter element, at this time, the mixed hair debris in the water will adhere to the surface of the first filter element facing the first cavity, and the filtered water will flow into the second cavity and flow out through the second interface. The setting of the filter device can perform secondary filtration on the sewage separated by the separation device, and further reduce the impurities carried in the water flowing out of the second outlet. The provision of the filtering device can improve the filtering effect of the filtering component, and the water flowing out of the second interface can flow to other water-using equipment or structures through the pipeline.

[0028] According to one embodiment of the present invention, the separation device includes a first section and a second section, the first section is constructed as a column section, and the fourth interface and the fifth interface are arranged on the first section; the second section is constructed as a cone section, the starting end of the cone section is connected to the first section, and the sixth interface is formed at the end of the cone section, and the diameter of the cone section gradually decreases in the direction from the starting end toward the end.

[0029] According to an embodiment of the present invention, the first section and the second section are coaxially arranged in the height direction.

[0030] The self-cleaning assembly according to the present invention is briefly described below.

[0031] The self-cleaning assembly according to the present invention includes the filter component and the pump housing in the above-mentioned embodiment, wherein a second accommodating chamber is formed in the pump housing, a second filter element is arranged in the second accommodating chamber, the inlet of the second accommodating chamber is communicated with the outlet of the clothing processing device, and the outlet of the second accommodating chamber is communicated with the fifth interface. Since the self-cleaning assembly according to the present invention is provided with the filter component in the above-mentioned embodiment, when the filter component is assembled with the pump housing, the water generated by the pump housing can enter the separation device through the fifth interface. After separation and treatment by the separation device, the clean water can flow back to the water return port or other water use structure of the clothing processing device for recycling, and the water mixed with hair debris flows into the filter device through the sixth interface for filtration. At this time, the second interface can be communicated with the second accommodating chamber in the pump housing, and the filtered water can enter the second accommodating chamber and be filtered again by the second filter element. The water after the second filtration by the second filter element flows back to the separation device, further reducing the impurities such as hair debris carried in the water flowing out of the fourth interface. It can be understood that the water flowing out of the clothing processing device is repeatedly circulated and filtered in the second accommodating chamber, the separation device and the first accommodating chamber, thereby improving the filtering capacity of the self-cleaning assembly. It is worth noting that when the self-cleaning assembly is in the filtering state, the water flowing out of the second interface can be filtered again in the second accommodating chamber; when the self-cleaning assembly is in the self-cleaning state, the water flowing out of the second interface will not be filtered when it flows into the second accommodating chamber but will be directly discharged to the outside through the sewage discharge pipe on the pump casing.

[0032] According to one embodiment of the present invention, the second filter element separates a clean water chamber and a sewage chamber in the pump housing, and a seventh interface and an eighth interface are formed on the pump housing. The seventh interface connects the clean water chamber with the fifth interface, and the eighth interface connects the second interface with the sewage chamber.

[0033] According to an embodiment of the present invention, a ninth interface is further provided on the pump housing, the ninth interface is connected to the sewage outlet of the clothing processing device, and a control valve that can be selectively opened or closed is provided in the ninth interface.

[0034] The clothes treating apparatus according to the present invention will be briefly described below.

[0035] The clothes processing device according to the present invention includes the self-cleaning assembly in the above embodiment. Since the clothes processing device according to the present invention includes the self-cleaning assembly in the above embodiment, the sewage generated by the clothes processing device can be filtered and purified by the self-cleaning assembly and then flow back to the water return port of the clothes processing device for reuse, thereby improving the utilization rate of water. In addition, the self-cleaning assembly can filter the sewage for multiple cycles, thereby avoiding secondary pollution caused by impurities such as hair scraps flowing back to the clothes processing device, thereby improving the user experience.

[0036] In summary, when the self-cleaning assembly is in the filtering state, the sewage generated by the clothing processing equipment can directly flow into the sewage chamber in the pump housing. After the sewage in the sewage chamber is filtered by the second filter element, the hair debris adheres to the surface of the second filter element, and the filtered water enters the clean water chamber. The seventh interface is connected to the fifth interface. The water in the clean water chamber can flow to the fifth interface through the seventh interface and enter the separation device. After entering the separation device, the hair debris and other impurities carried in the water move toward the end of the cone section under the action of gravity, and the water without hair debris flows back to the return water port of the clothing processing equipment through the fourth interface for secondary use. The water carrying hair debris separated by the separation device will flow out from the sixth interface and enter the filtering device through the first interface. The filtering device can filter the water flowing into the first interface. The water flowing into the first interface enters the first cavity. At this time, the first filter element is in a vertical position. The water in the first cavity enters the second cavity after being filtered by the first filter element, and the hair debris and other impurities adhere to the surface of the first filter element facing the first cavity. The water in the second cavity can flow to the eighth interface through the second interface and enter the sewage cavity to start circulation. The arrangement of the separation device, the filtering device and the pump housing enables the sewage generated by the clothing treatment equipment to be circulated and filtered in three different structures, reducing the impurity content of the water flowing back to the water return port of the clothing treatment equipment, and improving the filtering effect of the clothing treatment equipment and the utilization rate of water. When the self-cleaning assembly is in the self-cleaning state, the third interface is opened, and the clean water drives the first filter element to rotate to a horizontal position. The first interface and the second interface are respectively connected to the third cavity. The water flowing out of the first interface washes away the hair on the first filter element, and the water mixed with the hair flows from the second interface to the sewage cavity. At this time, the seventh interface is closed and the ninth interface is opened. The water in the sewage cavity can wash away the hair on the surface of the second filter element, and the water mixed with the hair flows to the sewage outlet through the ninth interface and is discharged to the outside. The self-cleaning function of the self-cleaning assembly realizes the cleaning of the filtering device and the pump housing, avoiding the hair residues being retained inside the self-cleaning assembly to cause secondary pollution, and the entire self-cleaning process does not require manual cleaning, which improves the user experience.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0060] 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 process 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 enters 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' experience of clothes processing equipment. 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. In addition, in existing self-cleaning equipment, due to insufficient filtering capacity, the water flowing back into the clothes processing equipment may form secondary pollution, affecting the user experience.

[0061] Reference below Figure 1-Figure 8 A filtering device according to an embodiment of the present invention is described.

[0062] The filtering device 1 according to the present invention comprises: a shell 11 and a first filter element 12, wherein a first accommodating chamber 111 is formed in the shell 11, and a first interface 112 and a second interface 113 communicating with the first accommodating chamber 111 are provided on the shell 11, and the first interface 112 is communicated with a water outlet of the clothing processing device 101; the first filter element 12 is movably arranged in the first accommodating chamber 111 to switch between a filtering state and a self-cleaning state, wherein: the first filter element 12 is suitable for separating the first accommodating chamber 111 into a first cavity 1111 and a second cavity 1112 in the filtering state, and the first interface 112 and the second interface 113 are respectively communicated with the first cavity 1111 and the second cavity 1112.

[0063] According to the filter device 1 of the present invention, a housing 11 and a first filter element 12 are provided. A first accommodating chamber 111 is formed in the housing 11. The first accommodating chamber 111 can be used to accommodate the first filter element 12. During assembly, the first filter element 12 can be movably arranged in the first accommodating chamber 111 so that the filter device 1 can filter the water entering the first accommodating chamber 111. Specifically, a first interface 112 and a second interface 113 are formed on the housing 11. The first interface 112 can be understood as the water inlet of the filter device 1. During assembly, the first interface 112 can be connected to the water outlet of the clothing processing device 101 so that the sewage generated by the clothing processing device 101 can flow into the filter device 1 for filtration; the second interface 113 can be understood as the water outlet of the filter device 1. During assembly, the second interface 113 can be connected to the sewage outlet or other drainage structure of the clothing processing device 101 so that the filtered water can be discharged from the filter device 1 through the second interface 113.

[0064] The filter device 1 can be divided into a filtering state and a self-cleaning state when working. The corresponding state can be selected according to needs when using the filter device 1. After the working state of the filter device 1 is selected, the first filter element 12 can be selectively moved in the first accommodating chamber 111 according to the real-time state of the filter device 1 to separate the first accommodating chamber 111 into two different cavities. The design of the first filter element 12 separating the first accommodating chamber 111 can avoid the mixing of sewage before filtration and water after filtration in the first accommodating chamber 111, resulting in secondary pollution, thereby affecting the filtering effect of the filter device 1.

[0065] Specifically, when the filter device 1 is in the filtering state, the first filter element 12 is in a vertical position, which can be understood as Figure 2 The position of the first filter element 12 shown in the figure, at this time, the first filter element 12 divides the first accommodating chamber 111 into a first cavity 1111 and a second cavity 1112, the first interface 112 is connected to the first cavity 1111, and the second interface 113 is connected to the second cavity 1112. The sewage entering the first accommodating chamber 111 through the first interface 112 can be filtered at the position of the first filter element 12, and impurities such as hair scraps are retained in the first cavity 1111 or on the side surface of the first filter element 12 facing the first cavity 1111; the filtered water enters the second cavity 1112 through the first filter element 12, and the water entering the second cavity 1112 can flow out through the second interface 113. The setting of the first filter element 12 can collect impurities in the sewage entering the filter device 1 in the first cavity 1111, so as to facilitate the subsequent centralized treatment of impurities. At the same time, the first filter element 12 can also separate the sewage before filtration and the water after filtration to avoid secondary pollution, thereby improving the filtering effect of the filter device 1.

[0066] When the filter device 1 is in the self-cleaning state, the first filter element 12 rotates until it is in a horizontal position. The horizontal position can be understood as Figure 3 , at this time, the water entering the first accommodating chamber 111 through the first interface 112 can wash away impurities such as hair debris adhering to the first filter element 12, and the fallen impurities can flow out of the filter device 1 through the second interface 113, thereby preventing hair debris from accumulating in the filter device 1 for a long time and affecting the filtering effect of the filter device 1 and the growth of bacteria. In addition, the first filter element 12 realizes the self-cleaning function of the filter device 1 through rotation, thereby avoiding additional manual operation and improving the user experience.

[0067] According to one embodiment of the present invention, the housing 11 is configured as a cylinder, the filter element is rotatably disposed in the first accommodating chamber 111, and the rotation axis of the first filter element 12 is coaxially disposed with the axis of the housing 11. Since the switching between the self-cleaning function and the filtering function of the filter device 1 is achieved by the rotation of the first filter element 12, and the first filter element 12 is movably disposed in the first accommodating chamber 111, the configuration of the housing 11 will affect the switching of the functions of the filter device 1. The filter device 1 configures the housing 11 as a cylinder, and then configures the first accommodating chamber 111 as a cylinder. The first accommodating chamber 111 of the cylindrical design facilitates the rotation of the first filter element 12. During assembly, the rotation axis of the first filter element 12 is coaxially disposed with the axis of the housing 11, and the axis of the housing 11 can be understood as the central axis of the housing 11. The coaxial configuration of the rotation axis of the first filter element 12 with the axis of the housing 11 can improve the stability of the first filter element 12 during rotation, and ensure that the filter device 1 can normally switch between the filtering state and the self-cleaning state when working.

[0068] According to one embodiment of the present invention, the shell 11 includes a side plate 115, a first end plate 116 and a second end plate 117. The side plate 115 is arranged around to define a first accommodating cavity 111 with both ends open; the first end plate 116 and the second end plate 117 are respectively arranged at both ends of the side plate 115 and respectively cooperate with the side plate 115 to close the first accommodating cavity 111, and the first end plate 116 and the second end plate 117 are respectively formed with a first interface 112 and a second interface 113, and the first filter element 12 is rotatably arranged on one of the first end plate 116 and the second end plate 117.

[0069] Since the housing 11 is the basic structure of the entire filter device 1, and the first filter element 12 is accommodated in the first accommodating chamber 111 defined by the housing 11, the structure of the housing 11 will affect the use of the filter device 1. The housing 11 is provided with a side plate 115, a first end plate 116, and a second end plate 117, wherein the side plate 115 is arranged in a surrounding manner so that the housing 11 is configured into a cylindrical shape, and at the same time, the side plate 115 also defines a first accommodating chamber 111 with both ends open, and the first filter element 12 can rotate in the first accommodating chamber 111. The side plate 115 is arranged in a surrounding manner so that the first accommodating chamber 111 is also configured into a cylindrical shape, which is convenient for the first filter element 12 to rotate. A first end plate 116 and a second end plate 117 are respectively provided at both ends in the extension direction of the side plate 115, wherein the first end plate 116 is fixedly connected to the side plate 115 to seal the open opening at one end of the first accommodating cavity 111, and the second end plate 117 can be selectively connected to the side plate 115 to close the open opening at the other end of the first accommodating cavity 111. The connection method of the first end plate 116, the second end plate 117 and the side plate 115 can achieve different effects on the filter device 1. For example: the fixed connection of the first end plate 116 and the side plate 115 can improve the structural strength of the shell 11; and the selective connection of the second end plate 117 and the side plate 115 facilitates the disassembly and assembly process of the first filter element 12.

[0070] The first end plate 116 is provided with a first interface 112, which connects the first accommodating chamber 111 with the clothing processing device 101 or other structures that provide water sources to be filtered so that the water to be filtered can enter the filter device 1 for filtering. The second end plate 117 is provided with a second interface 113, which can connect the first accommodating chamber 111 with the outside world or some water-using structures, so that the sewage in the filter device 1 in the self-cleaning state can be directly discharged or the filtered water in the filtering state can flow into other structures for reuse. In addition, during assembly, the first filter element 12 can be rotatably arranged on one of the first end plate 116 and the second end plate 117. Specifically, if the first filter element 12 is arranged on the first end plate 116, during assembly, the first filter element 12 can be installed through the open mouth at the other end of the first accommodating chamber 111 and matched with the first end plate 116; if the first filter element 12 is arranged on the second end plate 117, during assembly, the first filter element 12 can be first matched and connected with the second end plate 117 and then assembled with the second end plate 117. The two settings of the first filter element 12 can be selected according to the actual assembly situation, but it is worth noting that no matter whether the first filter element 12 is installed on the first end plate 116 or the second end plate 117, it will not rotate synchronously with the corresponding end plate. It can be understood that the assembled first filter element 12 and the corresponding end plate rotate relative to each other. Such a design scheme can ensure that after the filter device 1 is assembled as a whole, the first filter element 12 can rotate according to the real-time working status of the filter device 1, thereby ensuring the normal use of the filter device 1.

[0071] According to one embodiment of the present invention, in the axial projection of the housing 11, the first interface 112 and the second interface 113 are spaced apart in the circumferential direction. Since the water to be filtered flows into the filter device 1 from the first interface 112, is filtered by the first filter element 12, and then flows out of the filter device 1 from the second interface 113, the position layout of the first interface 112 and the second interface 113 will affect the filtering effect of the filter device 1. Specifically, in the axial projection of the housing 11, the first interface 112 and the second interface 113 are spaced apart in the circumferential direction. When the first filter element 12 is in Figure 2 In the initial position shown in , the first interface 112 and the second interface 113 can be connected to two different cavities respectively, so as to guide the sewage and the filtered water respectively. The position design of the first interface 112 and the second interface 113 makes the water inside the filter device 1 correspond to the first interface 112 and the second interface 113 respectively before and after filtering, ensuring that the unfiltered water will not flow out through the second interface 113 in the filtering state, thereby improving the filtering effect of the filter device 1.

[0072] According to one embodiment of the present invention, a first clamping portion 1151 is formed at the free end of the side plate 115, and a second clamping portion 1171 suitable for cooperating with the first clamping portion 1151 is formed on the second end plate 117. Since the second end plate 117 is connected to the other end of the side plate 115 for closing the first accommodating cavity 111, the connection method between the side plate 115 and the second end plate 117 will affect the sealing effect. The filter device 1 is provided with a first clamping portion 1151 at the free end of the side plate 115, and the free end of the side plate 115 can be understood as an end of the side plate 115 close to the second end plate 117. At the same time, a second clamping portion 1171 is provided on a side surface of the second end plate 117 facing the side plate 115. During assembly, the first clamping portion 1151 and the second clamping portion 1171 can be engaged and matched to achieve the connection between the second end plate 117 and the side plate 115, and improve the sealing effect.

[0073] In some embodiments, the first clamping portion 1151 can be configured as a clamping groove that is recessed at the free end of the side plate 115 toward the first end plate 116, and the second clamping portion 1171 can be configured as a clamping protrusion formed on the side of the second end plate 117 that faces the first end plate 116. During assembly, at least a portion of the clamping protrusion can be accommodated in the clamping groove, thereby improving the sealing performance of the second end plate 117 when sealing the first accommodating cavity 111. The edge of the second end plate 117 can also be processed with a fastener installation hole so that the second end plate 117 can be connected and fixed to the side plate 115 by the fastener, thereby improving the stability of the assembly of the second end plate 117.

[0074] According to an embodiment of the present invention, a first rotation groove 1161 is formed on the first end plate 116, and a second rotation groove 1172 is formed on the second end plate 117, and the first rotation groove 1161 and the second rotation groove 1172 are directly opposite to each other; the first filter element 12 is provided with a first rotating shaft 1212 and a second rotating shaft 1213 at both ends in the extension direction of the side plate 115, and the first rotating shaft 1212 and the second rotating shaft 1213 are coaxially arranged and respectively accommodated in the first rotating groove 1161 and the second rotating groove 1172. Since the first filter element 12 can rotate in the first accommodating chamber 111, the structure of the first end cover and the second end cover will affect the rotation of the first filter element 12.

[0075] Specifically, the filter device 1 is provided with a first rotation groove 1161 on a first end plate 116, and a second rotation groove 1172 on a second end plate 117. Meanwhile, the first filter element 12 is provided with a first rotating shaft 1212 and a second rotating shaft 1213 at both ends in the extension direction of the extension plate, respectively. During assembly, at least a portion of the first rotating shaft 1212 can be accommodated in the first rotation groove 1161, and at least a portion of the second rotating shaft 1213 can be accommodated in the second rotating groove 1172. During operation, the first rotating shaft 1212 and the second rotating shaft 1213 can rotate in the corresponding first rotating groove 1161 and the second rotating groove 1172, respectively. Meanwhile, the first rotating groove 1161 and the second rotating groove 1172 are axially opposite to each other, thereby improving the stability of the first filter element 12 during rotation.

[0076] According to an embodiment of the present invention, the first filter element 12 includes a bracket 121 and a filter screen 122, wherein a filter hole 1211 is formed on the bracket 121, the bracket 121 is rotatably arranged on one of the first end plate 116 and the second end plate 117, and the bracket 121 is respectively provided with a first rotating shaft 1212 and a second rotating shaft 1213 at both ends of the bracket 121 in the extension direction; and the filter screen 122 is arranged on the bracket 121. Since the first filter element 12 is a structure used for filtering in the filter device 1, the structure of the first filter element 12 will affect the filtering effect of the filter device 1. The first filter element 12 is constructed with a bracket 121 and a filter screen 122, wherein the bracket 121 is provided with a filter hole 1211, and the filter screen 122 is assembled on the bracket 121. When the filter device 1 is in a filtering state, the sewage flowing into the first accommodating chamber 111 through the first interface 112 can be filtered by the filter screen 122 and then flow out through the second interface 113, while the impurities such as hair scraps in the sewage are retained on the side surface of the filter screen 122 close to the first interface 112. The cooperation between the filter screen 122 and the filter holes 1211 realizes the filtering capability of the filter device 1 .

[0077] In addition, the bracket 121 is rotatably disposed on the first end plate 116 or the second end plate 117. Similar to the above-mentioned embodiment, the bracket 121 is provided with the above-mentioned first rotating shaft 1212 and the second rotating shaft 1213 at both ends in the extension direction. The first rotating shaft 1212 and the second rotating shaft 1213 are respectively accommodated in the first rotating groove 1161 and the second rotating groove 1172, so as to realize the relative rotation between the bracket 121 and the first end plate 116 or the second end plate 117, and improve the stability of the bracket 121 during rotation.

[0078] According to one embodiment of the present invention, at least one side edge of the bracket 121 in the width direction is provided with a water retaining rib 1214 extending in the circumferential direction, and a side surface of the water retaining rib 1214 close to the side plate 115 forms an arcuate water retaining surface that fits the inner wall of the side plate 115. Since the bracket 121 is rotatable in the first accommodating chamber 111, the structure of the bracket 121 will affect the filtering effect of the filtering device 1. Specifically, at least one side edge of the bracket 121 in the width direction is provided with a water retaining rib 1214, and the water retaining rib 1214 extends in the circumferential direction and a side surface of the water retaining rib 1214 close to the side plate 115 forms an arcuate water retaining surface that fits the inner wall of the side plate 115. During assembly, the arcuate water retaining surface can fit the inner wall of the first accommodating chamber 111, and the water retaining rib 1214 also seals the gap between the bracket 121 and the inner wall of the first accommodating chamber 111, avoiding the intersection of sewage and filtered water to cause secondary pollution, thereby improving the filtering effect of the filtering device 1.

[0079] According to one embodiment of the present invention, a first slide groove 1162 extending in the circumferential direction is formed on the first end plate 116, and / or a second slide groove 1173 extending in the circumferential direction is formed on the second end plate 117; an extension portion is provided on at least one side edge in the length direction of the bracket 121, and the extension portion is configured to be multiple and extends toward the first end plate 116 or the second end plate 117 respectively, and each extension portion is suitable for sliding in the corresponding first slide groove 1162 or the second slide groove 1173. Since the bracket 121 is rotatably provided on the first end plate 116 or the second end plate 117, the configuration of the first end plate 116 and the second end plate 117 will affect the rotation of the bracket 121. The filter device 1 is provided with a first slide groove 1162 on the first end plate 116, and the first slide groove 1162 extends in the circumferential direction and is configured as an arc. Similarly, the second end plate 117 is provided with a second slide groove 1173, and the second slide groove 1173 also extends in the circumferential direction and is configured as an arc. Correspondingly, the bracket 121 is provided with extension parts on both side edges in the length direction, and the extension parts are configured as multiple parts and extend toward the corresponding first end plate 116 or second end plate 117 respectively. When the filter device 1 needs to switch the state, the first filter element 12 rotates, and at this time, the extension part can slide along the corresponding first slide groove 1162 or second slide groove 1173. The provision of the first slide groove 1162, the second slide groove 1173 and the extension part further improves the stability of the first filter element 12 when it rotates.

[0080] In addition, the first slide groove 1162 and the second slide groove 1173 can also limit the rotation angle of the first filter element 12. Specifically, the first slide groove 1162 and the second slide groove 1173 can limit the rotation angle of the first filter element 12 according to the length of the processing during processing. For example, if the length of the first slide groove 1162 or the length of the second slide groove 1173 is greater than one-fourth of the length of the arc where they are located, the first filter element 12 can rotate at an angle greater than 90° when rotating; if the length of the first slide groove 1162 or the length of the second slide groove 1173 is greater than half of the length of the arc where they are located, the first filter element 12 can rotate at an angle greater than 180° when rotating. However, it is worth noting that in the present invention, in order to ensure the filtering effect and self-cleaning effect of the filter device 1, the length of at least one of the first slide groove 1162 and the second slide groove 1173 is set to one-fourth of the length of the arc where it is located. At this time, the rotation angle of the first filter element 12 is exactly 90°, that is, the first filter element 12 can rotate from Figure 2 The vertical position in the Figure 3In the horizontal position in the filter device 1, since the first filter element 12 switches the working state of the filter device 1 by rotating, and in the filtering state, the first filter element 12 is in a vertical state and the first filter element 12 faces the first cavity 1111, and impurities such as hair debris are attached to the surface of the first filter element 12 on one side. Therefore, when the filter device 1 is in the self-cleaning state, the first filter element 12 needs to be rotated 90° so that the surface of the first filter element 12 on which hair debris is attached can be washed off by the water sprayed from the first interface 112. In the self-cleaning state, if the angle of rotation of the first filter element 12 is too large, the water discharged from the first interface 112 will pollute the surface of the first filter element 12 on which hair debris is not attached; on the contrary, if the angle of rotation of the first filter element 12 is too small, the first interface 112 and the second interface 113 will not be connected to the same cavity, resulting in the inability to discharge hair debris. Therefore, the length of the first chute 1162 or the second chute 1173 is fixed to one-fourth of the length of the arc where they are located. Such a design ensures that the filter device 1 can realize the two functions of filtering state and self-cleaning state, and at the same time, it can also improve the versatility and processing efficiency of the processing mold.

[0081] In actual processing, the length of the first slide groove 1162 or the second slide groove 1173 will be affected by the positions of the first interface 112 and the second interface 113. Therefore, the specific processing plan can also be selected according to the actual situation. It is only necessary to ensure that the side surface of the first filter element 12 to which hair debris is not adhered will not be connected to the first interface 112 after rotation, and after rotation, the first interface 112 and the second interface 113 are connected to the same cavity.

[0082] According to one embodiment of the present invention, the first slide groove 1162 is configured as two symmetrically centered on the first end plate 116, and the second slide groove 1173 is configured as two symmetrically centered on the second end plate 117. Since the extension portion slides in the first slide groove 1162 and the second slide groove 1173, the configuration of the first slide groove 1162 and the second slide groove 1173 will affect the rotation of the first filter element 12. Specifically, the first filter element 12 is configured as two symmetrically centered on the first end plate 116, and the second slide groove 1173 is configured as two symmetrically centered on the second end plate 117. Correspondingly, each first slide groove 1162 and each second slide groove 1173 respectively accommodates an extension portion. The design scheme of symmetrically arranging the two first slide grooves 1162 and the two second slide grooves 1173 improves the stability of the filter device 1 during rotation.

[0083] According to one embodiment of the present invention, the filter device 1 further includes a driving device, which is disposed on the housing 11 and is suitable for driving the first filter element 12 to move so as to switch from a filtering state to a self-cleaning state. Since the first filter element 12 needs to rotate in the first accommodating chamber 111, the structure of the filter device 1 will affect the rotation of the first filter element 12. The filter device 1 is also provided with a driving device on the housing 11, which can drive the first filter element 12 to move so as to realize the transformation of the filter device 1 from a filtering state to a self-cleaning state. The structure of the driving device realizes the switching of the self-cleaning and filtering functions of the filter device 1.

[0084] According to one embodiment of the present invention, the driving device is configured as a connecting pipe 13 disposed on the housing 11, a channel is formed in the connecting pipe 13, the channel is connected to the first accommodating chamber 111, and the connecting pipe 13 can be selectively turned on. Since the driving device is a structure for driving the first filter element 12 to rotate, the structure of the driving device will affect the rotation of the first filter element 12. Specifically, the driving device is configured as a connecting pipe 13, the connecting pipe 13 is disposed on the housing 11 and connected to the structure for providing a clean water source, a channel is formed in the connecting pipe 13, and the channel can selectively turn on or off the first cavity 1111 and the structure for providing a clean water source. When the filter device 1 needs to be converted from a filtering state to a self-cleaning state, the filter device 1 can control the channel to be turned on, and the clean water is sprayed onto the first driving member through the connecting pipe 13 and drives the first driving member to rotate, thereby realizing the ability of the driving device to drive the first filter element 12 to rotate. At this time, the clean water source can also wash away a part of the hair attached to the surface of the first filter element 12 away from the clean water, thereby improving the self-cleaning effect of the filter device 1. In addition, the driving device is configured as the connecting pipe 13, which is environmentally friendly and does not require manual driving of the first filter element 12, and is simple and convenient to operate.

[0085] According to one embodiment of the present invention, a third interface 114 connected to the connecting pipe 13 is formed on the shell 11, and the first filter element 12 is suitable for defining a third cavity 1113 connected to the first interface 112 and the second interface 113 respectively and a fourth cavity 1114 connected to the third interface 114 in the first accommodating cavity 111 in the self-cleaning state. Since the connecting pipe 13 is arranged on the shell 11 and is connected to the first accommodating cavity 111, the connection position of the connecting pipe 13 and the shell 11 will affect the rotation of the first filter element 12. Specifically, the third interface 114 connected to the connecting pipe 13 is arranged on the shell 11, and the third interface 114 is connected to the second cavity 1112. It can be understood that when the first filter element 12 is in the self-cleaning state, Figure 2When the filter element 11 is in the vertical state, the water sprayed from the third interface 114 flows into the second cavity 1112. At this time, the water sprayed from the third interface 114 is orthogonal to the first filter element 12. Such a design scheme can make the water sprayed from the third interface 114 act on the first filter element 12 with greater force, thereby improving the driving efficiency of the driving device on the first filter element 12.

[0086] like Figure 3 As shown, when the filter device 1 is in the self-cleaning state, the first filter element 12 can define a third cavity 1113 and a fourth cavity 1114 in the first accommodating cavity 111, wherein the first interface 112 is connected to the third cavity 1113, the second interface 113 is also connected to the third cavity 1113, and the third interface 114 is connected to the fourth cavity 1114. It is worth noting that the first filter element 12 is rotated to Figure 3 When in the position shown in the figure, the surface of one side of the first filter element 12 with hair debris adhering to it is close to the third cavity 1113. At this time, the third interface 114 is directly opposite to the first filter element 12. The water sprayed from the third interface 114 can impact the first filter element 12 to rotate so as to realize the conversion of the filter device 1 from the filtering state to the self-cleaning state. The whole process does not require the setting of an additional driving structure, which is simple and convenient.

[0087] According to an embodiment of the present invention, in the filtering state, the projections of the third interface 114 and the second interface 113 on the first filter element 12 are respectively located on both sides of the rotation axis; in the self-cleaning state, the projections of the first interface 112 and the second interface 113 on the first filter element 12 are respectively located on both sides of the rotation axis. Since the water in the filter device 1 flows in or out through the first interface 112, the second interface 113 and the third interface 114, the position settings of the first interface 112, the second interface 113 and the third interface 114 will affect the function of the filter device 1.

[0088] Specifically, Figure 6As shown in , in the filtering state, the projections of the third interface 114 and the second interface 113 on the first filter element 12 are respectively located on both sides of the rotating shaft. It can also be understood that the projection of the third interface 114 on the first driving member falls on the upper half of the first driving member, and the projection of the second interface 113 on the first driving member falls on the lower half of the first driving member. At this time, the third interface 114 and the second interface 113 are located on the side of the first filter element 12 where the hair is not adhered and are connected to the second cavity 1112, and the first interface 112 is located on the side of the first filter element 12 where the hair is adhered and is connected to the first cavity 1111. The position design of the third interface 114 and the second interface 113 ensures that after the water sprayed from the third interface 114 drives the first filter element 12 to rotate, the surface of the side of the first filter element 12 where the hair is adhered is in a state away from the third interface 114, which avoids the water flowing into the first interface 112 during self-cleaning from causing secondary pollution to the clean side surface of the first filter element 12 and affecting the filtering capacity of the next time, thereby improving the filtering effect of the filtering device 1.

[0089] like Figure 7 As shown in , in the self-cleaning state, the projections of the first interface 112 and the second interface 113 on the first filter element 12 are respectively located on both sides of the rotating shaft, which can also be understood as the projection of the first interface 112 on the first drive member falls on the left half of the first drive member, while the projection of the second interface 113 on the first drive member falls on the right half of the first drive member. At this time, the first interface 112 and the second interface 113 are located on the side of the first filter element 12 where hair debris adheres and are respectively connected to the third cavity 1113, and the third interface 114 is located on the side of the first filter element 12 where hair debris is not adhered. The design scheme of the positions of the first interface 112 and the second interface 113 ensures that clean water can flow out of the second interface 113 in the filtering state, and the second interface 113 can directly discharge water mixed with hair debris in the self-cleaning state, thereby realizing the filtering function and self-cleaning function of the filter device 1.

[0090] According to one embodiment of the present invention, a one-way valve 103 is provided in the first interface 112 and the third interface 114. During assembly, the filter device 1 can be equipped with a one-way valve 103 in the first interface 112 and the third interface 114 to prevent the water in the first accommodating chamber 111 from flowing back from the first interface 112, and to prevent the water in the second cavity 1112 from escaping from the third interface 114 in the filtering state.

[0091] The filter assembly according to the present invention is briefly described below.

[0092] The filter assembly according to the present invention comprises the filter device 1 and the separation device 2 in the above-mentioned embodiment, wherein the separation device 2 is formed with a fourth interface 211, a fifth interface 212 and a sixth interface 221, the fourth interface 211 is communicated with the water outlet of the clothing processing device 101, the fifth interface 212 is communicated with the water return port 102 of the clothing processing device 101, and the sixth interface 221 is communicated with the first interface 112. Since the filter assembly according to the present invention is provided with the filter device 1 in the above-mentioned embodiment, the water generated by the clothing processing device 101 can enter the separation device 2 through the fourth interface 211, and the separation device 2 can process the water entering the separation device 2 itself to separate clean water and water mixed with hair. Under the action of the separation device 2, the clean water flows back to the water return port 102 of the clothing processing device 101 through the fifth interface 212 for secondary use, and the water mixed with impurities such as hair can flow to the first interface 112 through the sixth interface 221 and flow into the filter device 1 for filtration. The filter device 1 can filter the water introduced by the sixth interface 221 through the first filter element 12. At this time, the hair mixed in the water will adhere to the surface of the first filter element 12 on one side facing the first cavity 1111, and the filtered water will flow into the second cavity 1112 and flow out through the second interface 113. The setting of the filter device 1 can perform secondary filtration on the sewage separated by the separation device 2, further reducing the impurities carried in the water flowing out of the second outlet. The setting of the filter device 1 can improve the filtering effect of the filter assembly, and the water flowing out of the second interface 113 can flow to other water-using equipment or structures through the pipeline.

[0093] According to one embodiment of the present invention, the separation device 2 includes a first section 21 and a second section 22, the first section 21 is constructed as a column section, and a fourth interface 211 and a fifth interface 212 are provided on the first section 21; the second section 22 is constructed as a conical section, the starting end of the conical section is connected to the first section 21, and a sixth interface 221 is formed at the end of the conical section, and the diameter of the conical section gradually decreases in the direction from the starting end toward the end.

[0094] Since the separation device 2 can separate and process the water flowing out of the clothing processing device 101, the structure of the separation device 2 will affect the filtering effect of the filter assembly. Specifically, the separation device 2 includes a first section 21 and a second section 22, wherein the first section 21 is constructed as a column section, and a fourth interface 211 and a fifth interface 212 are provided on the column section, and the water flowing out of the clothing processing device 101 can enter the column section from the fourth interface 211; the second section 22 is constructed as a cone section, the starting end of the cone section is connected to the column section, and the end of the cone section forms a sixth interface 221, and the water entering the column section can flow into the cone section. Under the action of gravity, impurities such as hair scraps will flow into the cone section, thereby achieving the separation effect of the separation device 2. The diameter of the cone section gradually decreases from the starting end to the end, and the design scheme of the cone section diameter makes the flow rate of water below the cone section faster, improves the efficiency of hair scraps entering the cone section, and avoids the hair scraps from being directly discharged from the fourth interface 211, thereby improving the separation efficiency of the separation device 2.

[0095] According to one embodiment of the present invention, the first section 21 and the second section 22 are coaxially arranged in the height direction. Since the separation device 2 is composed of the first section 21 and the second section 22, the connection between the first section 21 and the second section 22 will affect the separation effect of the separation device 2. Figure 4 As shown in , the first section 21 and the second section 22 are coaxially arranged in the height direction. The coaxially arranged first section 21 and the second section 22 can make the hair scraps sink normally, thereby ensuring the separation function of the separation device 2.

[0096] The self-cleaning assembly according to the present invention is briefly described below.

[0097] The self-cleaning assembly according to the present invention includes the filter assembly and the pump housing 3 in the above-mentioned embodiment, wherein a second accommodating chamber is formed in the pump housing 3, a second filter element is arranged in the second accommodating chamber, the inlet of the second accommodating chamber is communicated with the outlet of the clothing processing device 101, and the outlet of the second accommodating chamber is communicated with the fifth interface 212. Since the self-cleaning assembly according to the present invention is provided with the filter assembly in the above-mentioned embodiment, when the filter assembly is assembled with the pump housing 3, the water generated by the pump housing 3 can enter the separation device 2 through the fifth interface 212, and after separation and processing by the separation device 2, the clean water can flow back to the clothing processing device 1 01 of the return water port 102 or other water-using structure for recycling, the water mixed with hair debris flows into the filter device 1 through the sixth interface 221 for filtration, at this time, the second interface 113 can be connected to the second accommodating chamber in the pump housing 3, the filtered water can enter the second accommodating chamber and be filtered again through the second filter element, and the water after the second filtration of the second filter element flows back to the separation device 2, further reducing the hair debris and other impurities carried in the water flowing out of the fourth interface 211. It can be understood that the water flowing out of the clothing processing device 101 is repeatedly circulated and filtered in the second accommodating chamber, the separation device 2 and the first accommodating chamber 111, thereby improving the filtering capacity of the self-cleaning assembly. It is worth noting that when the self-cleaning assembly is in the filtering state, the water flowing out of the second interface 113 can be filtered again in the second accommodating chamber; when the self-cleaning assembly is in the self-cleaning state, the water flowing out of the second interface 113 will not be filtered when it flows into the second accommodating chamber, but will be directly discharged to the outside through the pipeline for sewage discharge on the pump housing 3.

[0098] According to one embodiment of the present invention, the second filter element separates a clean water chamber and a sewage chamber in the pump housing 3, and a seventh interface 31 and an eighth interface 32 are formed on the pump housing 3. The seventh interface 31 connects the clean water chamber with the fifth interface 212, and the eighth interface 32 connects the second interface 113 with the sewage chamber. Since the pump housing 3 is connected to the separation device 2 and the filter device 1 respectively, the internal structure of the pump housing 3 will affect the filtering effect of the entire self-cleaning assembly. Specifically, a second accommodating chamber is provided in the pump housing 3, and the second filter element is provided in the second accommodating chamber and defines a clean water chamber and a sewage chamber in the second accommodating chamber. The sewage chamber can be understood as a chamber for storing impurities such as mixed hair or a chamber connected to a pipeline for outflowing sewage; the clean water chamber can be understood as a chamber into which sewage flows after being filtered by the second filter element. The pump housing 3 is provided with a seventh interface 31 and an eighth interface 32, wherein the seventh interface 31 can connect the clean water chamber with the fifth interface 212, so that the filtered water in the pump housing 3 flows to the separation device 2 for separation treatment; the eighth interface 32 can connect the second interface 113 with the sewage chamber, so that the water filtered by the filter device 1 enters the pump housing 3 and is filtered again by the second filter element, or the sewage generated by the self-cleaning of the filter device 1 flows into the sewage chamber and is discharged through the pump housing 3. The arrangement of the sewage chamber, the clean water chamber, the seventh interface 31 and the eighth interface 32 enables the filter device 1, the separation device 2 and the pump housing 3 to communicate with each other, realizes the circulation of the water path, and improves the filtering effect of the self-cleaning assembly.

[0099] According to one embodiment of the present invention, a ninth interface 33 is also provided on the pump housing 3, and the ninth interface 33 is connected to the sewage outlet of the clothing processing device 101, and a control valve that can be selectively turned on or off is provided in the ninth interface 33. Since the sewage in the self-cleaning state needs to be discharged from the sewage cavity, the structure of the pump housing 3 will affect the self-cleaning effect of the self-cleaning assembly. The self-cleaning assembly is provided with a ninth interface 33 on the pump housing 3, and the ninth interface 33 is connected to the sewage outlet of the clothing processing device 101. In the self-cleaning state, the sewage generated by the self-cleaning of the pump housing 3 and the sewage generated by the self-cleaning of the filter device 1 can flow from the sewage cavity through the ninth interface 33 to the sewage outlet and be discharged to the outside world, avoiding the excessive retention of impurities such as hair scraps in the sewage cavity and affecting the use of the self-cleaning assembly. In addition, a control valve is provided in the ninth interface 33, and the control valve can selectively control the conduction or closing of the ninth interface 33. The structure of the control valve makes the communication state between the sewage cavity and the ninth interface 33 controllable, avoiding the water in the circulating waterway from the ninth interface 33 in the filtering state.

[0100] The laundry treating apparatus 101 according to the present invention is briefly described below.

[0101] The clothes processing device 101 according to the present invention includes the self-cleaning assembly in the above-mentioned embodiment. Since the clothes processing device 101 according to the present invention includes the self-cleaning assembly in the above-mentioned embodiment, the sewage generated by the clothes processing device 101 can be filtered and purified by the self-cleaning assembly and then flow back to the return water port 102 of the clothes processing device 101 for reuse, thereby improving the utilization rate of water. In addition, the self-cleaning assembly can filter the sewage for multiple cycles, thereby avoiding secondary pollution caused by impurities such as hair scraps flowing back to the clothes processing device 101, thereby improving the user experience.

[0102] In some embodiments, the clothing processing device 101 may be a washing machine, a dryer, a washer-dryer, or the like.

[0103] To sum up, when the self-cleaning assembly is in the filtering state, the sewage generated by the clothing processing equipment 101 can directly flow into the sewage chamber in the pump housing 3. After the sewage in the sewage chamber is filtered by the second filter element, the hair debris adheres to the surface of the second filter element, and the filtered water enters the clean water chamber. The seventh interface 31 is connected to the fifth interface 212. The water in the clean water chamber can flow to the fifth interface 212 through the seventh interface 31 and enter the separation device 2. After entering the separation device 2, impurities such as hair debris carried in the water move toward the end of the cone section under the action of gravity, and the water without hair debris flows back to the return water port 102 of the clothing processing equipment 101 through the fourth interface 211 for secondary use. The water carrying hair separated by the separation device 2 will flow out from the sixth interface 221 and enter the filter device 1 through the first interface 112. The filter device 1 can filter the water flowing into the first interface 112. The water flowing into the first interface 112 enters the first cavity 1111. At this time, the first filter element 12 is in a vertical position. The water in the first cavity 1111 enters the second cavity 1112 after being filtered by the first filter element 12, while the hair and other impurities are attached to the side surface of the first filter element 12 facing the first cavity 1111. The water in the second cavity 1112 can flow to the eighth interface 32 through the second interface 113 and enter the sewage cavity to start circulation. The arrangement of the separation device 2, the filter device 1 and the pump housing 3 enables the sewage generated by the clothing treatment device 101 to be circulated and filtered in three different structures, reducing the impurity content of the water flowing back to the return port 102 of the clothing treatment device 101, and improving the filtering effect and water utilization rate of the clothing treatment device 101. When the self-cleaning assembly is in the self-cleaning state, the third interface 114 is opened, and the clean water drives the first filter element 12 to rotate to a horizontal position. The first interface 112 and the second interface 113 are respectively connected to the third cavity 1113. The water flowing out of the first interface 112 washes away the hair on the first filter element 12, and the water mixed with the hair flows from the second interface 113 to the sewage cavity. At this time, the seventh interface 31 is closed and the ninth interface 33 is opened. The water in the sewage cavity can wash away the hair on the surface of the second filter element, and the water mixed with the hair flows to the sewage outlet through the ninth interface 33 and is discharged to the outside. The self-cleaning function of the self-cleaning assembly realizes the cleaning of the filter device 1 and the pump housing 3, avoiding the hair residues being retained inside the self-cleaning assembly to cause secondary pollution, and the entire self-cleaning process does not require manual cleaning, which improves the user experience.
