[0057] In order to solve the problem of the need to regularly disassemble and clean the filter device, the present application proposes a filter device and a clothing processing device having the filter device. By using the filter device of the present application, the filter element in the filter device can be effectively cleaned without disassembling the filter device, and impurities attached to the filter element can be removed, thereby achieving the purpose of cleaning the filter element. Among them, the clothing processing device can be a washing machine, a washer-dryer or other clothing processing equipment with a drainage function. For the convenience of description, the present application only takes the clothing processing device as a washing machine as an example.

[0058] Combination Figures 1 to 5 As shown, in some embodiments of the present application, the filter device 1 includes a shell 10, a filter element 20 and a scraper 30. A accommodating cavity is formed inside the shell 10. The shell 10 is also provided with a water inlet 13 and a water outlet 14 connected to the accommodating cavity. The filter element 20 is arranged in the accommodating cavity and is located on a connecting channel 36 between the water inlet 13 and the water outlet 14. The spacing between at least part of the scraper 30 and the filter element 20 is smaller than the preset distance and can rotate relative to the filter element 20.

[0059] Specifically, the filter device 1 in the present application can be arranged in the drainage pipeline of the clothing processing equipment, and the waste water generated by the clothing processing equipment after washing clothes can enter the accommodating cavity of the housing 10 through the water inlet 13, and be discharged to the outside of the accommodating cavity through the water outlet 14. Among them, the water inlet 13 can be arranged at the top of the housing 10, and the water outlet 14 can be arranged at the bottom of the housing 10, so that the drainage is filtered through the filter element 20 during the flow of water.

[0060] Optionally, the housing 10 may be a substantially square structure, with extension ends provided at the top and bottom, respectively, and the extension ends are penetrated by a water inlet 13 or a water outlet 14 connected to the accommodating cavity, and the extension ends are provided to facilitate the connection of the water inlet 13 and the water outlet 14 to external pipes. The water inlet 13 may be connected to the laundry processing cavity of the laundry processing device through a connecting pipe, and the water outlet 14 may be connected to the drain pipe of the laundry processing device through a connecting pipe.

[0061] Optionally, the filter element 20 may be a mesh structure with a certain rigidity, so as to reduce its own deformation under long-term cooperation with the scraper 30. Optionally, the filter element 20 may be a plastic mesh, a metal mesh, a plastic plate with mesh, or a metal plate with mesh.

[0062] According to the filter device 1 of the present application, by arranging the filter element 20 on the connecting channel 36 between the water inlet 13 and the water outlet 14, the filter element 20 can effectively filter the water flow in the connecting channel 36 to remove impurities contained in the water flow. At the same time, the distance between the scraper 30 and the filter element 20 is less than the preset distance, and can rotate relative to the filter element 20. When it is necessary to remove impurities on the surface of the filter element 20, the scraper 30 is rotated to scrape the impurities attached to the surface of the filter element 20, thereby removing the impurities attached to the surface of the filter element 20, and then achieving the effect of cleaning the filter element 20, and there is no need to manually disassemble the filter device 1, reducing the burden on users. At the same time, through the filtering effect of the filter element 20, it is possible to reduce the direct discharge of microplastics and reduce environmental pollution.

[0063] In some embodiments of the present application, the maximum value of the preset distance is 0.1 mm.

[0064] Specifically, the maximum spacing between the scraper 30 and the filter 20 can be 0.1 mm. Specifically, the spacing between the two can be any value between 0.1 mm…0.09 mm…0.05 mm…0.01 mm…0. When the spacing between the scraper 30 and the filter 20 is 0, the scraper 30 and the filter 20 are in contact with each other, and the impurities attached to the surface of the filter 20 can be cleaned to the maximum extent.

[0065] Combination Figures 3 to 5As shown, in some embodiments of the present application, the scraper 30 includes a driving portion 31 and a scraper portion 32, and the spacing between the scraper portion 32 and the filter element 20 is smaller than a preset distance. The driving portion 31 can drive the scraper portion 32 to rotate together under the action of the water flow in the connecting channel 36.

[0066] Specifically, the driving part 31 is arranged on the connecting passage 36 between the water inlet 13 and the water outlet 14, and can be arranged below the water inlet 13. After the wastewater enters the accommodating chamber through the water inlet 13, it impacts the driving part 31, thereby causing the driving part 31 to rotate, and at the same time driving the scraping part 32 to rotate together, thereby causing the scraping part 32 to rotate relative to the filter element 20 and clean the impurities attached to the surface of the filter element 20, so as to remove the impurities attached to the surface of the filter element 20. Among them, the impurities attached to the surface of the filter element 20 include but are not limited to plastic debris, metal debris or hair debris. Among them, the attached Figure 3 The direction indicated by the black straight arrow is the direction of water flow in the connecting channel 36 .

[0067] Combination Figures 3 to 5 As shown, in some embodiments of the present application, the filter element 20 includes at least one arc surface, and the scraper 30 also includes at least one support rod 33, which is arranged in the accommodating cavity in a manner of rotating around an axis corresponding to the arc surface, and a scraping portion 32 is provided at the end of the support rod 33 in a direction perpendicular to the axis corresponding to the arc surface.

[0068] Specifically, the support rod 33 is arranged in the accommodating cavity in a manner that it can rotate around the axis corresponding to the arc surface, that is, the support rod 33 is arranged coaxially with the arc surface. Since the scraping portion 32 is arranged at the end of the support rod 33, the scraping portion 32 can always rotate around the axis corresponding to the arc surface, and the rotation radius of the scraping portion 32 is consistent with the radius corresponding to the arc surface, thereby increasing the contact area between the scraping portion 32 and the impurities on the arc surface, and effectively cleaning the filter element 20. Optionally, the arc surface can be a quarter circle.

[0069] Combination Figures 3 to 5 As shown, in some embodiments of the present application, the scraper 30 includes at least two support rods 33, one end of the at least two support rods 33 is connected to the inner wall surface of the shell 10 through the rotating shaft 40, and the other end of the at least two support rods 33 is spaced apart along the circumferential direction of the rotating shaft 40.

[0070] Specifically, the number of the support rods 33 can be four, one end of the four support rods 33 is connected to the rotating shaft 40 respectively, the two ends of the rotating shaft 40 are rotatably connected to the two inner wall surfaces of the housing 10 arranged opposite to each other, and the other ends of the support rods 33 are arranged at intervals along the circumferential direction. Since the other end of any support rod 33 away from the rotating shaft 40 is respectively provided with a scraping portion 32, the surface of the filter element 20 can be cleaned in turn by the four scraping portions 32 during the rotation of the scraper 30. Compared with only one support rod 33 and one scraping portion 32, the number of times the surface of the filter element 20 is cleaned during the rotation of the scraper 30 is four times the original number, thereby improving the cleaning effect of the filter element 20. Among them, the four support rods 33 can be independent structures respectively, and are respectively connected to the rotating shaft 40. Alternatively, at least two or all of the four support rods 33 are integrated structures and are provided with plug-in holes, and the rotating shaft 40 is plugged into the plug-in holes to connect with the support rods 33 and can drive the support rods 33 to rotate.

[0071] Combination Figures 3 to 5 As shown, in some embodiments of the present application, the driving portion 31 includes a water collection groove 311, which is arranged between the axis corresponding to the arc surface and the scraping portion 32, and the spacing dimension between the water collection groove 311 and the scraping portion 32 is smaller than the spacing dimension between the water collection groove 311 and the axis corresponding to the arc surface.

[0072] Specifically, the water trough 311 is disposed between the rotating shaft 40 and the scraping part 32, and the distance between the water trough 311 and the scraping part 32 is smaller than the distance between the water trough 311 and the rotating shaft 40. Since the driving part 31 is disposed on the support rod 33 near the scraping part 32, the distance between the driving part 31 and the rotating shaft 40 is increased, thereby increasing the driving torque of the driving part 31. Since the driving part 31 is driven by the impact of the water flow to drive the supporting rod 33 and the scraping part 32 to rotate together, the larger the distance between the driving part 31 and the rotating shaft 40, the greater the torque that the driving part 31 can provide, thereby driving the supporting rod 33 and the scraping part 32 to rotate quickly, thereby improving the cleaning effect of the filter element 20. By providing the water trough 311, the waste water flowing out of the water inlet 13 can fall into the water trough 311, thereby increasing the driving force of the driving part 31, so that the driving part 31 can drive the supporting part 33 and the scraping part 32 to rotate more quickly.

[0073] Combination Figures 3 to 5 As shown, in some embodiments of the present application, at least two scraping members 30 are provided corresponding to the same arc surface, and the at least two scraping members 30 are spaced apart along the axis corresponding to the arc surface.

[0074] Specifically, since the filter element 20 has a certain width dimension, if the filter element 20 is cleaned by only one scraper 30, it is necessary to increase the width dimension of the scraper portion 30 and the support strength of the support rod 33, thereby increasing the width dimension of the support rod 33. After the width dimension of the support rod 33 is increased, the resistance encountered by the scraper 30 during the rotation process is inevitably increased, thereby affecting the cleaning effect of the filter element 20. In the present application, by arranging at least two scrapers 30 along the axis corresponding to the arc surface, that is, arranging at least two scrapers 30 along the axis of the rotating shaft 40, the filter element 20 can be cleaned by multiple scrapers 30 together, and the multiple scrapers 30 can share one scraper portion 32 or respectively have one scraper portion 32, so that the width dimension of the support rod 33 can be correspondingly reduced, and the resistance encountered by the scraper 30 during the rotation process can be reduced. Furthermore, since the plurality of scraping members 30 are arranged at intervals along the axis of the rotating shaft 40, the support rods 33 between different scraping members 30 are arranged at intervals, and a hollow structure is formed between any two support rods 33, which further reduces the resistance of the scraping member 30 during the rotation process. The scraping portion 32 can be a rubber plate or a silicone sheet, and is sleeved on the end of the support rod 33. The rubber plate or the silicone sheet has a certain compressibility, thereby reducing the squeezing of the filter element 20, thereby reducing the deformation of the filter element 20.

[0075] Combination Figures 3 to 5 As shown, in some embodiments of the present application, the filter element 20 includes two arc surfaces, the two arc surfaces are respectively arranged below the water inlet 13, and the top ends of the two arc surfaces are connected, the bottom ends of the two arc surfaces are respectively arranged on both sides of the top connection, and the two arc surfaces are respectively provided with scrapers 30.

[0076] Specifically, the filter element 20 includes a first arc 21 and a second arc surface 22, and the first arc surface 21 and the second arc surface 22 are arranged opposite to each other, and the first arc surface 21 and the second arc surface 22 are respectively provided with a scraper 30. Figure 3As shown, wastewater flows into the accommodating chamber through the water inlet 13, and is discharged through the water outlet 14 after being filtered by the filter element 20. In this process, impurities contained in the wastewater adhere to the first arc surface 21 and the second arc surface 22. The scraper 30 corresponding to the first arc surface 21 rotates clockwise under the impact of the water flow, and the scraper portion 32 rubs against the impurities attached to the first arc surface 21, thereby removing the impurities attached to the first arc surface 21 during the rotation of the scraper 30, and the removed impurities fall to the bottom of the side of the accommodating chamber corresponding to the first arc surface 21. The scraper 30 corresponding to the second arc surface 22 rotates counterclockwise under the impact of the water flow, and the scraper portion 32 rubs against the impurities attached to the second arc surface 22, thereby removing the impurities attached to the second arc surface 22 during the rotation of the scraper 30, and the removed impurities fall to the bottom of the side of the accommodating chamber corresponding to the second arc surface 22.

[0077] By providing the first arc surface 21 and the second arc surface 22 , it is possible to effectively reduce the impurities deposited on one side of the accommodating cavity after cleaning, and reduce the impurities deposited on one side of the accommodating cavity from continuing to clog the filter element 20 .

[0078] The housing 10 includes a first housing portion 11 and a second housing portion 12 that are detachably connected, the first housing portion 11 is provided with a water inlet 13, and the second housing portion 12 is provided with a water outlet 14. When a certain amount of impurities are deposited in the accommodating chamber, the first housing portion 11 and the second housing portion 12 can be disassembled to remove the impurities in the accommodating chamber, so that the filtering device 1 can continue to be used.

[0079] At the same time, in order to allow the bottom of the accommodating cavity to accommodate more impurities, the bottom of the first arc surface 21 and the bottom of the second arc surface 22 are respectively spaced apart from the inner bottom surface of the shell 10 .

[0080] Combination Figures 3 to 6 As shown, in some embodiments of the present application, a guide cavity 111 is further provided inside the shell 10, and the guide cavity 111 is connected to the water inlet 13. The guide cavity 111 is also provided with at least two guide ports 112 connected to the accommodating cavity, and the at least two guide ports 112 are consistent with the number of the scraping members 30 and are arranged one-to-one.

[0081] By setting the guide cavity 111 and the guide port 112, the guide port 112 is set one-to-one with the scraper 30, and the wastewater enters the guide cavity 111 through the water inlet 13, and impacts the scraper 30 through the guide port 112, thereby increasing the impact force of the wastewater on the scraper 30, increasing the rotation speed of the scraper 30, and further improving the cleaning effect on the filter 20.

[0082] Specifically, three scrapers 30 are correspondingly arranged on the first arc surface 21, and three scrapers 30 are correspondingly arranged on the second arc surface 22. Correspondingly, the flow guide cavity 111 is provided with six flow guide ports 112, and the six flow guide ports 112 are arranged in two rows, and three flow guide ports 112 are arranged at intervals in any row along the width direction of the filter element 20, and the six flow guide ports 112 are respectively arranged opposite to the driving parts 31 of the six scrapers 30.

[0083] Combination Figures 7 to 11 As shown, in some embodiments of the present application, at least part of the filter element 20 is a cylindrical structure, the scraping portion 32 is sleeved on the outside of the cylindrical structure, and the driving portion 31 is disposed at one end of the cylindrical structure and connected to the scraping portion 32 .

[0084] Specifically, the housing 10 includes a first housing portion 11 and a second housing portion 12 that are detachably connected. The second housing portion 12 is a cylindrical structure with an opening at one end. The first housing portion 11 is connected to the second housing portion 12 at one end with an opening. The water inlet 13 and the water outlet 14 are respectively arranged in the first housing portion 11 and are arranged at intervals in the circumferential direction. The filter element 20 is arranged in the communication channel 36. After the wastewater enters the accommodating chamber through the water inlet 13, it is filtered by the filter element 20 and finally discharged to the outside of the housing 10 through the water outlet 14. In this process, impurities contained in the wastewater adhere to the outer surface of the filter element 20. The drive portion 31 drives the scraper portion 32 to rotate. The scraper portion 32 can effectively remove the impurities attached to the outer surface of the filter element 20, thereby achieving the purpose of cleaning the filter element 20. The removed impurities fall to the bottom of the accommodating chamber. When the impurities in the accommodating chamber are deposited to a certain amount, the impurities in the accommodating chamber can be removed by disassembling the first housing portion 11 and the second housing portion 12, so that the filter device 1 can be used continuously. The filter element 20 may be a plastic mesh cylinder or a metal mesh cylinder. Fig.10 The direction indicated by the black straight arrow is the direction of water flow in the connecting channel 36 .

[0085] At the same time, in order to allow the bottom of the accommodating cavity to accommodate more impurities, the bottom surface of the filter element 20 is spaced apart from the inner bottom surface of the housing 10 .

[0086] Combination Figures 9 to 11 As shown, in some embodiments of the present application, the scraping portion 32 is a spiral structure.

[0087] By configuring the scraping portion 32 as a spiral structure, the spiral structure can form a cylindrical cleaning surface during the rotation of the scraping portion 32 , thereby effectively cleaning the surface of the filter element 20 .

[0088] Combination Figures 9 to 11As shown, in some embodiments of the present application, a first through hole 35 is provided through the center position of the driving portion 31, and a plurality of guide blades 312 are provided around the surface of the driving portion 31 facing away from the scraping portion 32. The guide blades 312 can rotate around the axis of the first through hole 35 under the impact of the water flow in the connecting channel 36.

[0089] Specifically, due to the arrangement of the first through hole 35, the waste water in the communication channel 36 can flow to the water outlet 14 through the first through hole 35. In the process of the waste water flowing to the water outlet 14 through the first through hole 35, the guide blade 312 can rotate around the axis of the first through hole 35 under the impact of the water flow, thereby driving the scraper 30 to rotate together, and then the outer surface of the filter 20 is cleaned by the scraper 30.

[0090] Among them, a connecting part 34 is also connected between the driving part 31 and the scraping part 32, the bottom of the connecting part 34 is connected to the scraping part 32, and a guide blade 312 is provided on the top of the connecting part 34. A receiving groove is also provided at one end of the first shell part 11 facing the second shell part 12, and the receiving groove is directly connected to the water outlet 14. The driving part 31 and the connecting part 34 are inserted into the receiving groove together, and a mounting groove is provided between the driving part 31 and the connecting part 34. A connecting piece matching the inner wall surface of the receiving groove may be provided in the mounting groove. The scraping member 30 is rotatably connected to the first shell part 11 through the connecting piece, and the bottom of the scraping member 30 is spaced from the inner bottom surface of the shell 10. Optionally, the connecting piece may be a rubber ring or a bearing.

[0091] Combination Figures 9 to 11 As shown, in some embodiments of the present application, the guide vane 312 includes a first plate portion 3121 and a second plate portion 3122 , and the first plate portion 3121 and the second plate portion 3122 are arranged at an angle.

When the water flows through the first through hole 35 to the water outlet 14, it can impact the first plate portion 3121, thereby driving the scraper 30 to rotate, and then cleaning the surface of the filter 20. The second plate portion 3122 is used to cooperate with the first plate portion 3121, thereby reducing the loss of water when the water impacts the first plate portion 3121, increasing the water flow used to impact the first plate portion 3121, and thereby improving the rotation effect of the scraper 30.

[0093] Combination Figures 9 to 11As shown, in some embodiments of the present application, the connecting channel 36 includes a first connecting channel 361 and a second connecting channel 362, the first connecting channel 361 is arranged between the shell 10 and the outer peripheral surface of the cylindrical structure, and the second connecting channel 362 is arranged inside the cylindrical structure, and the water inlet 13, the first connecting channel 361, the second connecting channel 362 and the water outlet 14 are connected in sequence.

[0094] By setting the above-mentioned water channel structure, the contact area between the wastewater and the outer surface of the filter element 20 can be increased, so as to maximize the attachment of impurities contained in the wastewater to the outer surface of the filter element 20, and the impurities attached to the outer surface of the filter element 20 can be removed by rotating the scraper 30.

[0095] Combination Figures 9 to 12 As shown, in some embodiments of the present application, an overflow channel 50 is further provided inside the shell 10 , the water inlet end of the overflow channel 50 is connected to the first connecting channel 361 , and the water outlet end of the overflow channel 50 is connected to the second connecting channel 362 .

[0096] When the surface of the filter element 20 is blocked due to excessive impurities in the second housing portion 12, an overflow channel 50 is also provided inside the first housing portion 11 to enable the filter device 1 to drain water normally. After the wastewater enters the first connecting channel 361 through the water inlet 13, it can flow into the second connecting channel 362 through the overflow channel 50. In this process, although the wastewater cannot remove impurities through the filter element 20, the filter device 1 can drain water normally and reduce the sound of the blockage phenomenon. Among them, the first housing portion 11 is provided with a second through hole 15, and the wastewater flowing out of the overflow channel 50 enters the first housing portion 11 and is discharged into the second connecting channel 362 through the second through hole 15.

[0097] Combination Figures 9 to 12 As shown, in some embodiments of the present application, a float valve 60 is further included. The float valve 60 is disposed in the overflow channel 50 , and the float valve 60 is provided with an opening pressure for conducting the overflow channel 50 .

[0098] By setting the opening pressure of the float valve 60 , the overflow channel 50 can be opened according to different blockage conditions in the accommodating chamber, thereby reducing further blockage in the accommodating chamber.

[0100] Specifically, the clothing processing device 100 includes a housing 2, which forms the appearance structure of the clothing processing device 100, and is provided with an installation cavity inside the housing, and the installation cavity is used to install the clothing processing cylinder and various components. The clothing processing cylinder is arranged in the installation cavity, and the clothing processing cylinder is arranged in the horizontal direction or at an angle with the horizontal direction, wherein when the clothing processing cylinder is arranged at an angle with the horizontal direction, the angle size is very small, and the clothing processing cylinder as a whole is still roughly arranged in the horizontal direction. A clothing processing cavity 201 is provided inside the clothing processing cylinder, which is used to store clothing, so as to wash and dry clothing. A delivery port connected to the clothing processing cavity 201 is provided at the front end of the clothing processing cylinder, and a door body 3 is also connected to the front end of the housing 2. By operating the door body 3, the delivery port can be opened or closed, so that clothing can be delivered into the clothing processing cavity 201 through the delivery port, and then the clothing can be washed. Specifically, the door body 3 is connected to the housing 2 in a rotatable manner.

[0101] Since the clothing processing device 100 of the present application has the same technical features as the filtering device 1 in any of the above-mentioned embodiments and can achieve the same technical effects, it will not be described in detail here.
