[0043] The following describes the filter device 100 of the cleaning equipment according to the embodiment of the present invention with reference to the accompanying drawings.

[0044] Reference Figure 1 、 Figure 2 According to the filter device 100 of the embodiment of the present invention, the filter device 100 includes: a base 10 and a centrifugal filter 20.

[0045] The base 10 is provided with a centrifugal chamber 11, a slag collecting chamber 12, and a slag collecting chamber inlet 13 connecting the centrifugal chamber 11 and the slag collecting chamber 12. The centrifugal filter 20 is cylindrical and rotatably disposed within the centrifugal chamber 11. The slag collecting chamber inlet 13 has a first edge 131 and a second edge 132. The second edge 132 and the first edge 131 are spaced apart and arranged opposite each other in the circumferential direction of the centrifugal chamber 11. The first edge 131 is connected to the inner wall of the centrifugal chamber 11, and the second edge 132 is connected to the inner wall of the slag collecting chamber 12. A tangential surface A passes through the first edge 131 and is tangential to the inner wall of the centrifugal chamber 11. The second edge 132 is located on the side of the tangential surface A that is closer to the centrifugal chamber 11.

[0046] Among them, the centrifugal filter 20 is rotatably arranged in the centrifugal chamber 11. The cleaning equipment usually uses cleaning liquid during cleaning. The cleaning liquid is mixed with dirt after cleaning. The centrifugal filter 20 plays a filtering role and recycles the cleaning liquid. The centrifugal filter 20 rotates and guides the dirt into the slag collecting chamber 12 through centrifugal action.

[0047] It should be noted that the cleaning equipment can be a dishwasher, and the cleaning liquid is mixed with food residues after cleaning the tableware. The centrifugal filter 20 filters the residue and then discharges the residue into the residue collecting chamber 12 through centrifugal action; or, the cleaning equipment can also be other, such as a floor scrubber, in which a centrifugal chamber 11 and a residue collecting chamber 12 are provided, and a centrifugal filter 20 is provided in the centrifugal chamber 11 to recycle water; the cleaning equipment can also be a car washing machine, in which a centrifugal chamber 11 and a residue collecting chamber 12 are provided, and the centrifugal filter 20 is used to remove mud and dirt in the water so as to maintain the cleaning effect when recycling the water.

[0048] In the related art, cleaning equipment needs to filter various dirt, such as food residues, mud or other foreign matter. Various dirt will be concentrated in the dirt collecting chamber, but the dirt is difficult to move and the dirt is not discharged smoothly.

[0049] In the embodiment of the present invention, a centrifugal filter 20 is provided in the centrifugal chamber 11, and the dirt is thrown away by centrifugal action, and the dirt is guided into the slag collecting chamber 12 through the slag collecting chamber inlet 13, and the second edge 132 of the slag collecting chamber inlet 13 is provided on the side of the tangential surface A close to the centrifugal chamber 11, and the slag collecting chamber inlet 13 has a guiding function. The slag collecting chamber inlet 13 is larger, and the movement of the dirt is smoother, so that the dirt is discharged into the slag collecting chamber 12 more smoothly, thereby improving the smoothness of the dirt movement.

[0050] It should be noted that the tangential plane A is a virtual plane, which is a fictitious plane for the convenience of understanding. The tangential plane A is tangent to the first edge 131 .

[0051] Specifically, one end of the slag collecting chamber inlet 13 is connected to the centrifugal chamber 11, and the other end is connected to the slag collecting chamber 12. The first edge 131 is the edge where the slag collecting chamber inlet 13 intersects with the centrifugal chamber 11, and the second edge 132 is the edge where the slag collecting chamber inlet 13 intersects with the slag collecting chamber 12. The tangential surface A is tangent to the first edge 131, and the second edge 132 is on the inner side of the tangential surface A.

[0052] According to the filtering device 100 of the embodiment of the present invention, a centrifugal filter 20 is provided, and the second edge 132 of the slag collecting chamber inlet 13 is provided on one side of the tangential surface A. The second edge 132 is located on the side of the tangential surface A close to the centrifugal chamber 11. The setting of the slag collecting chamber inlet 13 makes the movement of dirt smoother. The slag collecting chamber inlet 13 guides the movement of dirt, thereby improving the smoothness of the movement of dirt.

[0053] Reference Figure 2 、 Figure 10 In some specific embodiments, a centrifugal drain port 111 is further provided on the base 10, which is connected to the centrifugal cavity 11. The centrifugal filter 20 is covered with the centrifugal drain port 111. The clean liquid filtered by the centrifugal filter 20 is discharged from the centrifugal cavity 11 through the centrifugal drain port 111, while the dirt cannot pass through the centrifugal filter 20 and remains outside the centrifugal filter 20.

[0054] In some embodiments, the slag collecting chamber inlet 13 has a first wall 133 away from the first edge 131 , the second edge 132 is provided on the first wall 133 , and the angle between the first wall 133 and the tangential plane A is θ1, 0≤θ1≤90°.

[0055] The slag collecting chamber inlet 13 is a channel with a certain length, and the first wall surface 133 is an inner wall of the slag collecting chamber inlet 13 .

[0056] In the above solution, by setting θ1 within the range of 0 to 90°, the obstruction to the dirt is reduced and the smoothness of the movement of the dirt is improved.

[0057] For example, θ1 is 45°; or, θ1 is 0°, and the first wall surface 133 is parallel to the tangential surface A; or, θ1 is 80°.

[0058] Reference Figure 3 In some specific embodiments, the slag collecting chamber inlet 13 has a first wall 133 away from the first edge 131 , the second edge 132 is provided on the first wall 133 , and the first wall 133 is parallel to the tangential plane A.

[0059] In the above solution, by arranging the first wall surface 133 to be parallel to the tangential surface A, the obstruction to the dirt is reduced, so that the dirt can pass through the slag collecting chamber inlet 13 more smoothly.

[0060] Reference Figure 3 In some embodiments, the slag collecting chamber inlet 13 has a second wall surface 134 , and the second wall surface 134 is opposite to and parallel to the first wall surface 133 .

[0061] The slag collecting chamber inlet 13 is a channel with a certain length. The second wall 134 is an inner wall of the slag collecting chamber inlet 13 different from the first wall 133 . The second wall 134 and the first wall 133 are opposite surfaces.

[0062] In the above solution, by arranging the second wall surface 134 to be parallel to the first wall surface 133 , that is, the second wall surface 134 is parallel to the tangential surface A, the obstruction to the dirt is further reduced, so that the dirt passes through the slag collecting chamber inlet 13 more smoothly.

[0063] In some specific embodiments, the slag collecting chamber inlet 13 has a second wall 134 , which is opposite to the first wall 133 . The second wall 134 is configured as a curved wall, and the curvature of the curved wall faces the center of the centrifugal chamber 11 .

[0064] In the above solution, by constructing the second wall surface 134 as an arc wall, the slag collecting chamber inlet 13 can fully utilize the corners of the base 10 and connect the relatively distant centrifugal chamber 11 and the slag collecting chamber 12 in a smaller size.

[0065] Reference Figure 5 In some embodiments, the base 10 is provided with a sewage collecting chamber 14, a centrifugal chamber inlet 15 and a sewage collecting chamber outlet 141. The centrifugal chamber inlet 15 connects the sewage collecting chamber 14 and the centrifugal chamber 11, and the sewage collecting chamber outlet 141 connects the sewage collecting chamber 14. The filtering device 100 includes a residue collecting filter element 30. The residue collecting filter element 30 is cylindrical and is arranged in the sewage collecting chamber 14 and covers the sewage collecting chamber outlet 141.

[0066] Among them, the cylindrical residue collection filter 30 is covered on the sewage collecting chamber outlet 141, and the residue collection filter 30 plays a filtering role. The centrifugal chamber inlet 15 connects the sewage collecting chamber 14 and the centrifugal chamber 11. The clean liquid mixed with dirt first enters the sewage collecting chamber 14, and then enters the centrifugal chamber 11 after being filtered by the residue collection filter 30. The filtered clean liquid is discharged into the sewage collecting chamber outlet 141 for subsequent recycling.

[0067] In the above solution, by providing the residue collecting filter 30 at the outlet 141 of the dirt collecting chamber, the cleaning liquid mixed with dirt is first filtered by the residue collecting filter 30, thereby improving the cleanliness.

[0068] Reference Figure 4 In some embodiments, the centrifugal chamber inlet 15 is disposed near the bottom of the centrifugal chamber 11 .

[0069] The centrifugal chamber inlet 15 is provided on the side wall of the centrifugal chamber 11 , and the centrifugal chamber inlet 15 is close to the bottom of the centrifugal chamber 11 , and the cleaning liquid enters the centrifugal chamber 11 near the bottom of the centrifugal chamber 11 .

[0070] In the above solution, by arranging the centrifugal chamber inlet 15 near the bottom of the centrifugal chamber 11 , the cleaning liquid can disturb the sediment at the bottom of the centrifugal chamber 11 and prevent dirt from accumulating at the bottom of the centrifugal chamber 11 .

[0071] Specifically, the centrifugal chamber 11 is a cavity structure, and the centrifugal chamber inlet 15 is opened at the bottom of the cavity structure. The clean liquid entering the centrifugal chamber 11 flows to disturb the dirt in the centrifugal chamber 11 and prevent the dirt from being deposited at the bottom.

[0072] In other embodiments, the centrifugal chamber inlet 15 is disposed at the bottom of the centrifugal chamber 11 , and the cleaning liquid flows into the centrifugal chamber 11 from bottom to top.

[0073] Reference Figure 4 In some embodiments, the bottom wall of the centrifugal chamber 11 is flush with the bottom wall of the sewage collecting chamber 14 , and the bottom wall of the centrifugal chamber inlet 15 is flush with the bottom wall of the centrifugal chamber 11 .

[0074] Among them, the bottom wall of the centrifugal chamber 11 is flush with the bottom wall of the dirt collecting chamber 14, and the bottom wall surface of the centrifugal chamber inlet 15 is set at a lower position. The bottom wall surface of the centrifugal chamber inlet 15 is flush with the bottom wall of the centrifugal chamber 11, and the cleaning liquid entering the centrifugal chamber 11 can disturb the dirt contacting the bottom wall.

[0075] In the above solution, by setting the bottom wall surface of the centrifugal chamber inlet 15 flush with the bottom wall of the centrifugal chamber 11, the cleaning liquid disturbs the dirt at the bottom of the centrifugal chamber 11, further reducing the probability of dirt accumulation and improving cleanliness.

[0076] Reference Figure 4In some embodiments, in the depth direction of the centrifugal chamber 11 , the height of the centrifugal chamber inlet 15 is H1 , the depth of the centrifugal chamber 11 is H2 , and H1 ≥ 1 / 2H2 .

[0077] The centrifugal chamber inlet 15 is provided on the centrifugal chamber 11 and has a certain height. The cleaning liquid flows through the centrifugal chamber inlet 15 and enters the centrifugal chamber 11 .

[0078] In the above solution, by setting H1≥1 / 2H2, the centrifugal chamber inlet 15 is opened larger, so that the flow of the cleaning liquid is smoother. At the same time, the cleaning liquid entering the centrifugal chamber 11 can affect a larger area, thereby improving the disturbance effect.

[0079] For example, H1 is equal to 1 / 2H2; or, H1 is equal to 5 / 8H2; or, H1 is equal to 2 / 3H2; or, H1 is equal to 7 / 8H2; or, H1 is equal to H2.

[0080] Reference Figure 4 In some embodiments, in the depth direction of the centrifugal chamber 11 , the bottom wall surface of the slag collecting chamber inlet 13 is located above the top wall surface of the centrifugal chamber inlet 15 .

[0081] The depth direction of the centrifugal chamber 11 is the axial direction of the centrifugal chamber 11 , the bottom wall surface of the slag collecting chamber inlet 13 is located above the top wall surface of the centrifugal chamber inlet 15 , and the slag collecting chamber inlet 13 is located above the centrifugal chamber inlet 15 .

[0082] In the above scheme, by setting the bottom wall surface of the slag collecting chamber inlet 13 to be located on the upper side of the top wall surface of the centrifugal chamber inlet 15, in the centrifugal chamber 11, the cleaning liquid flows from bottom to top, driving the dirt to flow upward, disturbing the dirt in the centrifugal chamber 11, and preventing the slag collecting chamber inlet 13 from being blocked.

[0083] In some embodiments, the slag collecting chamber inlet 13 is disposed near the top of the slag collecting chamber 12 .

[0084] The slag collecting chamber inlet 13 is close to the top of the slag collecting chamber 12 , and dirt enters the slag collecting chamber 12 from a higher position.

[0085] In the above solution, by arranging the slag collecting chamber inlet 13 close to the top of the slag collecting chamber 12 , dirt enters the slag collecting chamber 12 from a higher position, preventing the dirt in the slag collecting chamber 12 from flowing back into the centrifugal chamber 11 .

[0086] Reference Figure 2 In some embodiments, the base 10 is provided with a slag collecting chamber outlet 17, which is connected to the slag collecting chamber 12. The filtering device 100 includes a slag collecting filter 50, which is cylindrical and can be pivotally disposed in the slag collecting chamber 12 and covered on the slag collecting chamber outlet 17.

[0087] Among them, the slag filter 50 plays a filtering effect to further filter out dirt. The base 10 is provided with a slag chamber outlet 17, which is connected to the slag chamber 12. The slag chamber outlet 17 is used to discharge the filtered clean liquid from the slag chamber 12, thereby recycling the clean liquid.

[0088] In the above solution, by providing a residue collecting filter 50 to filter out dirt, the filtering effect is further improved, and the multiple filtration further improves the utilization rate of the cleaning liquid.

[0089] In some specific embodiments, the base 10 is further provided with a slag discharge port, which is connected to the slag collecting chamber 12 to discharge waste in a unified manner.

[0090] Reference Figure 6 In some embodiments, the filter device 100 further includes a driving assembly 40, which is disposed on the base 10. The driving assembly 40 has a rotating end 41, which is connected to the centrifugal filter 20 and the slag filter 50 to drive the centrifugal filter 20 and the slag filter 50 to rotate.

[0091] The driving assembly 40 is installed on the base 10 , and the rotating end 41 of the driving assembly 40 is connected to the centrifugal filter screen 20 and the slag collection filter screen 50 to drive the centrifugal filter screen 20 and the slag collection filter screen 50 to rotate.

[0092] In the above solution, by providing a drive assembly 40 connecting the centrifugal filter 20 and the slag filter 50, the drive assembly 40 can drive both the centrifugal filter 20 and the slag filter 50, thereby reducing the number of components and making the structure more compact.

[0093] Specifically, the drive assembly 40 includes: a drive motor 42, a first gear 43 and a second gear 44. The rotating end 41 of the drive motor 42 engages with the first gear 43, and the first gear 43 drives the centrifugal filter 20 to rotate through the first rotating shaft 431. The second gear 44 engages with the first gear 43, and the second gear 44 drives the slag filter 50 to rotate through the second rotating shaft 441.

[0094] Reference Figure 7 、 Figure 10 In some specific embodiments, a polygonal groove 23 is provided on the centrifugal filter 20, and the first rotating shaft 431 is provided with a matching portion 432 corresponding to the polygonal groove 23. The matching portion 432 is inserted into the polygonal groove 23 to drive the centrifugal filter 20 to rotate.

[0095] Reference Figure 7 、 Figure 10In some embodiments, the base 10 is provided with an opening 112 communicating with the centrifugal chamber 11 , and the filter device 100 further includes a cover 60 , which is detachably covered on the opening 112 and pivotally connected to the centrifugal filter screen 20 .

[0096] In the related art, cleaning equipment needs to filter various impurities, such as food residues, mud or other foreign matter. The cleaning equipment cleans the impurities through the centrifugal action of the centrifugal filter, but the centrifugal filter is usually fixed to the base. The centrifugal filter cannot be cleaned well and produces odor after long-term use.

[0097] In the above scheme, the centrifugal filter 20 is positioned using the cover plate 60, and the cover plate 60 is removable. During the subsequent maintenance and repair process, the cover plate 60 can be removed and the centrifugal filter 20 can be taken out of the centrifugal chamber 11 for cleaning, thereby facilitating subsequent maintenance and repair and avoiding the generation of odor after long-term use.

[0098] Among them, the cover plate 60 is detachably arranged on the opening 112. When the cover plate 60 is fixed on the opening 112, the cover plate 60 blocks the opening 112 and the cover plate 60 closes the centrifugal chamber 11. After the cover plate 60 is removed from the opening 112, the opening 112 is opened, the centrifugal chamber 11 is opened, and the centrifugal filter 20 can be taken out from the opening 112.

[0099] Reference Figure 10 In some specific embodiments, a sealing member 65 is provided between the cover 60 and the base 10 to enhance the sealing performance. For example, the sealing member 65 is a sealing ring.

[0100] Reference Figure 7 、 Figure 8 In some embodiments, a rotating assembly 70 is provided between the centrifugal filter 20 and the cover plate 60. The rotating assembly 70 includes a first sub-assembly 71 and a second sub-assembly 72. The first sub-assembly 71 is fixedly connected to the centrifugal filter 20, and the second sub-assembly 72 is fixedly connected to the cover plate 60. The first sub-assembly 71 and the second sub-assembly 72 are rotatably connected.

[0101] Among them, the rotating component 70 is arranged between the centrifugal filter 20 and the cover plate 60, and the centrifugal filter 20 is rotatably connected to the cover plate 60 by using the rotating component 70. The first sub-component 71 of the rotating component 70 is fixedly connected to the centrifugal filter 20, for example, the first sub-component 71 and the centrifugal filter 20 are interference fit, or threadedly connected, so that the first sub-component 71 and the centrifugal filter 20 remain relatively stationary; the second sub-component 72 is fixedly connected to the cover plate 60, for example, the second sub-component 72 and the cover plate 60 are interference fit, or threadedly connected, so that the second sub-component 72 and the cover plate 60 remain relatively stationary.

[0102] In the above scheme, by providing a rotating assembly 70, the centrifugal filter 20 and the cover plate 60 are connected by the rotating assembly 70, the first sub-component 71 is fixedly connected to the centrifugal filter 20, and the second sub-component 72 is fixedly connected to the cover plate 60. When the cover plate 60 is removed, the centrifugal filter 20 moves with the cover plate 60, thereby simplifying the disassembly steps of the centrifugal filter 20. For example, when the cover plate 60 is lifted, the centrifugal filter 20 is lifted together, and there is no need to perform a separate operation on the centrifugal filter 20, thereby simplifying the steps.

[0103] For example, the rotating component 70 is a bearing; or, the first sub-component 71 is an annular component, which is fixed to the centrifugal filter 20, and the second sub-component 72 is a columnar component, which is fixed to the cover plate 60.
