DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0032] See also Figures 1 to 3 The embodiment of the present application provides a filter 100, including a shell 110, a partition 50 and a filter screen 60, at least a portion of the partition 50 is located in the shell 110, the partition 50 divides the inner cavity of the shell 110 into a front cavity and a rear cavity, a portion of the shell 110 corresponding to the front cavity is provided with a liquid inlet 111, a portion of the shell 110 corresponding to the rear cavity is provided with a liquid outlet, the partition 50 is provided with a hollow portion 51, the filter screen 60 is embedded in the hollow portion 51 and is connected to the partition 50.

[0033] Exemplarily, the diameter of the mesh of the filter 60 is less than 5 mm.

[0034] In some embodiments, the diameter of the mesh of the filter 60 is 0.5 mm to 5 mm, for example, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc.

[0035] The filter 100 provided in the embodiment of the present application, by setting a partition 50 in the shell 110, divides the inner cavity of the shell 110 into a front cavity and a rear cavity, so that the sewage can first be precipitated in the front cavity after entering the shell 110, so that the microplastics and lint in the sewage are precipitated once. The sewage after the first precipitation is filtered through the filter net 60 embedded in the partition 50 to filter out most of the microplastics and lint. The filtered sewage then enters the rear cavity for secondary precipitation, so that finer microplastics and lint in the sewage are precipitated. After precipitation, the clean water above is discharged from the filter through the liquid outlet, so that the filter can achieve the effect of filtering the microplastics and lint in the sewage, thereby reducing the pollution of the washing machine sewage to the environment.

[0036] See also Figure 2 The shell 110 includes a front cover 10 and a rear cover 20. The front cover 10 and the partition 50 together enclose the front cavity, and the rear cover 20 and the partition 50 together enclose the rear cavity.

[0037] See also Figures 2 to 4 The front cover 10 includes a first cover body 11 and a first cylinder body 12 which are connected to each other. The first cover body 11 is provided with the liquid inlet 111 , and the first cylinder body 12 is connected to the partition 50 .

[0038] Please combine Figure 5 The rear cover 20 includes a second cover body 21 and a second cylinder body 22 which are connected to each other. The second cover body 21 is provided with the liquid outlet, and the second cylinder body 22 is connected to the partition 50 .

[0039] Please combine Figure 5 The second cover body 21 and the second cylinder body 22 may be an integral structure.

[0040] Please combine Figure 2 and Figure 6 The filter 100 further includes a flip plate 70 . An opening 52 is provided at an edge of the partition 50 . The flip plate 70 is rotatably connected to the partition 50 at the opening 52 .

[0041] Please combine Figure 2 and Figure 6 For example, a first rotating shaft and a second rotating shaft can be respectively provided on both sides of the flip plate 70, and the respective axial center lines of the first rotating shaft and the second rotating shaft are located on the same straight line. A first rotating hole and a second rotating hole can be respectively provided on the partition 50, and the first rotating shaft and the second rotating shaft can be respectively inserted into the first rotating hole and the second rotating hole to realize the connection between the flip plate 70 and the partition 50, and since the first rotating shaft and the second rotating shaft can respectively rotate in the first rotating hole and the second rotating hole, the flip plate 70 can be rotated relative to the partition 50.

[0042] Please combine Figure 2 and Figure 6 A perspective window 121 is provided on the first cylinder 12 , and the perspective window 121 is located at one end of the first cylinder 12 close to the partition 50 .

[0043] It should be noted that when the filter screen 60 on the partition 50 is not blocked and works normally, the liquid level of the sewage in the front chamber is low and the sewage cannot reach the flip plate 70. At this time, the flip plate 70 and the partition 50 remain parallel (both are in a vertical state); when there are too many microplastics and lint in the sewage entering the filter 100, causing the filter screen 60 on the partition 50 to be blocked, at this time, the liquid level of the accumulated water in the front chamber rises. When the liquid level of the sewage reaches the position of the flip plate 70, the action of the water flow causes the vertical flip plate 70 to flip into a horizontal state. Because the flip plate 70 itself is painted with bright colors, the horizontally placed flip plate 70 is below the perspective window 121, so that the user can perceive it, thereby acting as an alarm. At this time, it is necessary to manually open the filter 100 and clean the microplastics and lint deposited in the filter 100.

[0044] Please combine Figure 2In the direction from the hollow portion 51 of the partition 50 to the opening 52 of the partition 50 , the orthographic projection of the liquid outlet on the partition 50 is higher than the position of the filter screen 60 .

[0045] It should be noted that by setting the orthographic projection of the liquid outlet on the partition 50 higher than the location of the filter 60, that is, making the height of the liquid outlet higher than the location of the filter 60, at this time, it is possible to prevent the water filtered from the filter 60 from directly entering the liquid outlet and then being discharged from the filter, but the water filtered from the filter 60 can be secondary deposited in the back cavity, so that the finer microplastics and wire scraps in the water filtered from the filter 60 are secondary precipitated. After precipitation, the clean water above can enter the liquid outlet and be discharged from the filter, thereby further improving the filtering effect of the filter. In addition, when the height of the liquid outlet is higher than the location of the filter 60, there will be accumulated water in the back cavity of the filter 100, and the height of the accumulated water is higher than the filter 60, which allows the filter 60 to remain moist, which is convenient for cleaning the microplastics and wire scraps attached to the filter 60 at a later time.

[0046] Please combine Figure 2 and Figure 4 The front cover 10 also includes a plurality of filter columns 14, which are connected to the inner surface of the first cylinder 12. In the direction from the hollow portion 51 of the partition 50 to the opening 52 of the partition 50, the orthographic projections of the plurality of filter columns 14 on the first cover body 11 are located below the liquid inlet 111.

[0047] Please combine Figure 2 and Figure 4 The plurality of filter columns 14 extend in a direction from the hollow portion 51 of the partition plate 50 to the opening 52 of the partition plate 50 .

[0048] It can be understood that when the sewage enters the front chamber from the liquid inlet 111, the filter column 14 located in the front chamber can form resistance to the flow of water, slowing down the flow of water in the front chamber, making it easy for plastic and wire scraps in the sewage to settle down, and the filter column 14 can make the wire scraps easily entangled thereon, thereby retaining the wire scraps.

[0049] Please combine Figure 4 , multiple filter columns 14 are arranged in an array. It can be understood that the filter columns 14 arranged in an array can make the wire scraps easier to entangle.

[0050] Please combine Figure 3 The front cover 10 further includes a flow guide member 30 , which is connected to the first cover body 11 and is located in the front cavity.

[0051] Please combine Figure 3The drainage member 30 and the first cover body 11 enclose a drainage cavity, and the drainage cavity is connected to the liquid inlet 111. The drainage member 30 includes a bottom 31 connected to the first cover body 11 and a side portion 32 connected to the bottom 31, the side portion 32 has a lower edge 321 and an upper edge 322 arranged opposite to each other, and a left edge 323 and a right edge 324 arranged opposite to each other, the lower edge 321 is connected to the bottom 31, the two ends of the left edge 323 are respectively connected to one end of the upper edge 322 and the bottom 31, and the two ends of the right edge 324 are respectively connected to the other end of the upper edge 322 and the bottom 31;

[0052] There are spaces between the upper edge 322 , the left edge 323 , the right edge 324 and the first cover body 11 .

[0053] It can be understood that since there are gaps between the upper edge 322, the left edge 323, the right edge 324 of the side 32 of the guide member 30 and the first cover body 11, that is to say, the water coming out of the guide member 30 can flow out from the gap between the upper edge 322 and the first cover body 11 (flow out upward), flow out from the gap between the left edge 323 and the first cover body 11 (flow out to the left), and flow out from the gap between the right edge 324 and the first cover body 11 (flow out to the right), that is to say, the water outflow of the guide member 30 has three directions, namely upward, left and right, so as to avoid the water flow directly impacting the accumulated water at the bottom of the front cavity downward. This is because the violent flow of accumulated water is not conducive to the precipitation of microplastics and lint. The design of the present application allows the water flow to slowly enter the front cavity, which is conducive to keeping the accumulated water in the front cavity calm, and then helps to fully precipitate the microplastics and lint in the washing machine sewage in the front cavity, thereby improving the filtering effect.

[0054] Please combine Figure 2 and Figure 3 A first protrusion 112 is provided on the edge of the first cover body 11 , and the first protrusion 112 is embedded in the first cylinder body 12 , so that the first cylinder body 12 is snap-connected with the first cover body 11 .

[0055] Please combine Figure 3 For example, the first protrusion 112 may be annular, and the first cylinder 12 may be cylindrical. When the first protrusion 112 is embedded in the first cylinder 12, a sealed connection between the first cylinder 12 and the first cover 11 may be achieved, thereby achieving the sealing of the front cavity.

[0056] Please combine Figure 2 and Figure 4A convex edge 13 is provided at one end of the first cylinder 12 away from the first cover body 11, and the convex edge 13 is arranged around the first cylinder 12. The convex edge 13 includes a bottom edge 131 connected to the first cylinder 12 and a side edge 132 connected to the bottom edge 131 away from the first cylinder 12. The bottom edge 131 and the side edge 132 surround a slot, and the partition 50 is clamped in the slot. The end of the second cylinder 22 away from the second cover body 21 is clamped in the slot.

[0057] Please combine Figure 2 and Figure 4 For example, the convex edge 13 can be annular, the partition 50 can be circular, and the second cylinder 22 can be cylindrical. When the partition 50 is clamped in the groove formed by the convex edge 13, the partition 50 is sealed and connected to the inner wall of the convex edge 13, thereby achieving isolation between the front cavity and the rear cavity. When the second cylinder 22 is clamped in the groove formed by the convex edge 13 from the side of the partition 50 away from the first cover body 11, the second cylinder 22 is sealed and connected to the inner wall of the convex edge 13, thereby achieving the sealing of the rear cavity.

[0058] See also Figures 1 to 3 as well as Figure 5 The filter 100 also includes a liquid inlet pipe 41 and a liquid outlet pipe 42. The liquid inlet pipe 41 is arranged on the outside of the first cover body 11 and connected to the first cover body 11, and the liquid inlet pipe 41 is connected to the liquid inlet port 111; the liquid outlet pipe 42 is arranged on the outside of the second cover body 21 and connected to the second cover body 21, and the liquid outlet pipe 42 is connected to the liquid outlet port.

[0059] An embodiment of the present application further provides a washing machine, comprising a washing machine body and a filter 100 connected to a drain outlet of the washing machine body, wherein the filter 100 is the filter 100 in any of the above embodiments.

Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application.
