[0038] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings 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 creative work are within the scope of protection of the present application.

[0039] See also Figure 1 As shown, Figure 1A schematic diagram of the structure of a washing machine provided in an embodiment of the present application. An embodiment of the present application provides a washing machine 1, which can be a drum washing machine or a pulsator washing machine, and the embodiment of the present application does not make specific restrictions. For ease of explanation, the embodiment of the present application is described by taking a drum washing machine as an example. The washing method of the drum washing machine is designed to imitate the principle of hitting clothes with a mallet. It consists of a stainless steel inner drum, a mechanical program controller, a triple-protected outer shell that has been phosphated, electrophoresed, and sprayed, and a number of heavy cement blocks for balancing the huge centrifugal force generated when the drum rotates to perform repeated movements, and the combined action of washing powder and water makes the clothes clean. In other words, the inner drum of the drum washing machine is in a horizontal position, and the opening of the inner drum faces the horizontal direction. The inner drum can rotate around the horizontal axis, and the lifting ribs in the inner drum are combined to drive the clothes to turn over, so that the clothes can be washed or dried evenly.

[0040] Exemplarily, the washing machine 1 includes a main body 100 and a drain pipe 200. The main body 100 is a structure including components such as a box body, an inner drum, a display panel, and a control panel. The main body 100 can hold and process clothes, that is, the main body 100 is a main component for washing clothes. The drain pipe 200 is detachably connected to the main body 100, such as by plugging and connecting through a plug-in pipe. The drain pipe 200 is used to discharge the sewage after the main body 100 processes the clothes, such as discharging it into a sewer through a drain port.

[0041] Among them, although the washing machine will filter and collect some slightly larger lint or fluff in the washing machine during the washing process, it does not process the microplastics, but directly discharges them. Microplastics, or microfibers, refer to plastic particles with a size of less than 5 mm. Microplastics also contain harmful substances, such as dyes, which can easily lead to ecological pollution problems. Therefore, it is necessary to set up a filter component at the drainage of the washing machine to collect microplastics. However, the existing filter components can only collect microplastics. When the microplastics block the filter components, water leakage caused by excessive pressure in the filter components is likely to occur.

[0042] In order to reduce the occurrence of the above-mentioned problems, the embodiment of the present application provides a filter component 300, which can filter and collect microplastics, reduce pollution to the ecology, and can use the rear filter net to filter when the front filter net in the filter component 300 is blocked, thereby reducing water leakage caused by excessive pressure in the filter component and extending the service life of the filter component 300.

[0043] It is understandable that the filter assembly 300 is used in the washing machine 1, but it can also be sold separately like the drain pipe 200. That is to say, the filter assembly 300, the drain pipe 200 and the main body 100 can be three independent products that can be sold separately or used in combination, and thus sold as a set. For the sake of convenience of explanation, the embodiment of the present application classifies the filter assembly 300 as a part of the washing machine 1, and it should not be understood that the filter assembly 300 must be included in the washing machine 1.

[0044] The filter assembly 300 is arranged on the drain pipe 200, or in other words, the filter assembly 300 is arranged on the drainage path of the drain pipe 200. During installation, the drain pipe 200 can be divided into two sections, and the filter assembly 300 is sandwiched between the two sections of the drain pipe, so that water passes through the filter assembly 300 to filter and collect microplastics in the drain pipe 200. Of course, the filter assembly 300 can also be connected to the end of the drain pipe 200, so that the water filtered by the filter assembly 300 is directly discharged. Among them, the filter assembly 300 can be installed on the side of the body 100 through a hook structure or a double-sided adhesive structure, and the top of the filter assembly 300 is not higher than the area of ​​the drainage pump head.

[0045] It should be noted that the water filtered by the filter assembly 300 in the embodiment of the present application can be directly discharged into the sewer. Since it has been filtered, at least part of the microfibers can be filtered out, thereby reducing the pollution to the ecology. Of course, the water filtered by the filter assembly 300 can also be recycled, such as connecting one end of the drain pipe 200 to the sewer, and then connecting the end branch of the drain pipe 200 to the water supply system of the body 100, so as to achieve water recycling and reduce the waste of resources.

[0046] The filter assembly 300 is not limited to being used in the washing machine 1. For example, the filter assembly 300 can also be set at the drain pipe of the washing pool, so as to remove microplastics in the washing pool and reduce the pollution of microplastics to the ecology. Of course, the filter assembly 300 can also be used in other scenarios, any scenario that can filter microplastics, and no examples are given here.

[0047] Please combine Figure 1 Also see Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the structure of the filter assembly provided in the embodiment of the present application from a first angle. Figure 3 for Figure 2 The cross-sectional structure diagram of the filter assembly along AA is shown. Exemplarily, the filter assembly 300 includes a box body 310 and at least two drawers 320 .

[0048] The box body 310 can be made of plastic, which has a certain strength and low cost. The box body 310 is used to place the drawer 320, and the drawer 320 includes a filter, so that at least part of the microplastics can be filtered out through the box body 310 to reduce the pollution to the ecological environment. The shape of the box body 310 can be set to adapt to the shape of the filter. Among them, the box body 310 is provided with a water inlet 311 and a water outlet 312. The water inlet 311 is used to connect with the water outlet of the drain pipe 200, and the water outlet 312 is used to discharge the water filtered by the filter in the box body 310. The water outlet 312 can be connected to the drain pipe 200, and the water outlet 312 can also be directly connected to the sewer outlet.

[0049] At least two drawers 320 are arranged in the box body 310, and at least two drawers 320 are located between the water inlet 311 and the water outlet 312. Each drawer 320 includes a filter 321, and at least the drawer 320 close to the water inlet 311 is provided with a drain port 322, which is located above the filter 321 to drain when the filter 321 below it is blocked, so that even if the filter 321 close to the water inlet 311 is blocked, microplastics can be filtered through the filter 321 far from the water inlet 311, which can reduce the water leakage caused by excessive pressure in the box body 310 due to the blockage of the filter 321, and extend the service life of the filter assembly 300.

[0050] In the filter assembly 300 provided in the embodiment of the present application, at least two drawer parts 320 for filtering are arranged in the filter assembly 300, and at least the drawer part 320 close to the water inlet 311 is provided with a drain port 322. Thus, when the front filter net 321 is blocked, the rear filter net 321 can be used for filtering through the drain port 322, thereby reducing the water leakage problem caused by the excessive water pressure in the filter assembly 300 breaking through the box body 310, and extending the service life of the filter assembly 300.

[0051] For example, please combine Figures 1 to 3 Also see Figure 4 As shown, Figure 4 The exploded structural diagram of the filter assembly provided in the embodiment of the present application is shown in FIG. The inner wall of the box body 310 is provided with a slide groove 313 , which is used to install the drawer 320 , fix the drawer 320 , and facilitate the installation and removal of the drawer 320 .

[0052] Each drawer 320 further includes a bracket 323, which is slidably connected to the slide slot 313. The bracket 323 is provided with a mounting port 3230 and a drain port 322, the drain port 322 is located above the mounting port 3230, and the mounting port 3230 is used to install the filter 321. It can be understood that the bracket 323 is used to install the filter 321 on the one hand, and is used to connect with the box body 310 on the other hand to fix the filter 321, and is also used to open the drain port 322 on the third hand.

[0053] Exemplarily, each drawer 320 further includes a mounting frame 324, which is used to mount the filter 321, and the mounting frame 324 is mounted on the mounting opening 3230. It is understandable that the mounting frame 324 is a frame structure for mounting the filter 321, and compared with the filter being directly connected to the bracket, the filter 321 can be easily disassembled and cleaned, and when the filter 321 is damaged, there is no need to replace the entire drawer 320, only the filter 321 needs to be replaced, which can reduce material costs.

[0054] Among them, the filter net 321 is installed on the end of the installation frame 324 away from the water inlet 311, and the filter net 321 and the installation frame 324 are surrounded by a filter groove 325. On the one hand, the filter groove 325 can partition the water flow to prevent the water entering from the water inlet 311 from directly rushing onto the filter net 321, which may easily cause damage to the filter net 321; on the other hand, the filter groove 325 can also collect the microplastics intercepted by the filter net 321, thereby reducing the difficulty in cleaning the internal space of the box body 310 caused by the scattering of microplastics.

[0055] A handle 3232 may also be provided on the bracket 323 of the drawer 320 , and the handle 3232 is located at the top, so that the user can pull out the drawer 320 through the handle 3232 .

[0056] Illustratively, the filter assembly 300 of the embodiment of the present application may include three drawer members 320, and each of the three drawer members 320 may be provided with a drain port 322, so that when any filter net 321 is blocked, filtering can be performed through other filter nets 321, thereby reducing the excessive pressure in the box body 310 caused by blockage, which may easily cause water leakage, and extending the service life of the filter assembly 300.

[0057] The mesh size of the filter nets 321 in the three drawers 320 can be gradually reduced from the water inlet 311 to the water outlet 312, so that microplastics of different sizes can be filtered and intercepted, and the accuracy of microplastic filtration can be improved. Of course, the mesh size of the filter nets 321 in the three drawers 320 can also be the same, so as to achieve triple filtration of microplastics, which can also improve the accuracy of microplastic filtration from another perspective.

[0058] For example, please combine Figures 1 to 4 Also see Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram of the structure of the filter assembly provided in the embodiment of the present application from a second angle. Figure 6 A schematic diagram of the structure of the filter assembly provided in the embodiment of the present application from a third angle. The box body 310 is provided in a split configuration, for example, the box body 310 includes a main shell 314 and a cover 315. The main shell 314 is a major component of the box body 310, and the main shell 314 is used to contain the drawer 320, or the drawer 320 is provided in the main shell 314. The cover 315 is detachably connected to the main shell 314 to cover or expose the main shell 314.

[0059] The detachable connection between the main shell 314 and the cover 315 is achieved by mutually cooperating snaps and a rotating shaft. Exemplarily, the box body 310 also includes a first snap 316a and a second snap 316b. The first snap 316a is arranged on the main shell 314, and the second snap 316b is arranged on the cover 315. The second snap 316b is connected to the first snap 316a by snapping, so that the cover 315 can be detachably mounted on the main shell 314. For example, the first snap 316a can be a convex block, and the second snap 316b can be a slot, and the slot and the convex block can be connected by snapping. Of course, the first snap 316a can also be set as a slot, and the second snap 316b can be set as a convex block. The above is only illustrated by example and should not be understood as a limitation to the first snap 316a and the second snap 316b.

[0060] It is understandable that the snap-fit ​​component is a component that tightly connects the cover body 315 and the main shell 314. In order to prevent water leakage of the box body 310, a sealant such as a silicone material can also be set between the cover body 315 and the main shell 314.

[0061] Exemplarily, in order to facilitate the placement of the cover body 315 when the cover body 315 is separated from the main shell 314, the cover body 315 can be set as a flip cover structure, thereby preventing the cover body 315 from being lost. Exemplarily, the box body 310 also includes a rotating shaft 317a and a sleeve 317b. The rotating shaft 317a and the first snap member 316a are arranged at opposite ends of the main shell 314, and the sleeve 317b and the second snap member 316b are arranged at opposite ends of the cover body 315. The sleeve 317b cooperates with the rotating shaft 317a to flip the cover body 315 relative to the main shell 314 to a set angle. Among them, a limiter (not shown in the figure) can also be set to limit the flip angle of the cover body 315 to prevent the cover body 315 from falling off due to the cover body 315 flipping too large.

[0062] It should be noted that the embodiment of the present application also designs the relative position relationship between the water inlet 311 and the water outlet 312 to increase the water path, thereby increasing the collection efficiency of microplastics.

[0063] Exemplarily, the box body 310 further includes a water-passing shell 318 , which is disposed protruding from the main shell 314 and is communicated with the main shell 314 , and the water inlet 311 is disposed on the water-passing shell 318 .

[0064] Among them, the water-passing shell 318 is arranged at one end of the main shell 314 along the arrangement direction of at least two drawers 320, and the projection of the water-passing shell 318 on the main shell 314 is located inside the main shell 314, thereby saving materials and avoiding interference or disturbance to the connection between the cover body 315 and the main shell 314. Exemplarily, the water inlet 311 and the water outlet 312 are staggered on the top wall and the bottom wall of the box body 310, that is, the water inlet 311 is arranged on the water-passing shell 318, and is located above or through the top wall of the water-passing shell 318, and the water outlet 312 is located below or on the bottom wall of the main shell 314, and the two are staggered, and at least two drawers 320 are arranged between the water inlet 311 and the water outlet 312, so that the water entering from the water inlet 311 is discharged through the water outlet 312 after passing through at least two drawers 320, so as to achieve the filtration of microplastics in sewage.

[0065] In the filter assembly 300 and the washing machine 1 provided in the embodiment of the present application, at least two drawer components 320 for filtering are arranged in the filter assembly 300, and at least the drawer component 320 close to the water inlet 311 is provided with a drain port 322. Thus, when the front filter net 321 is blocked, the rear filter net 321 can be used for filtering through the drain port 322, thereby reducing the problem of water leakage caused by the excessive water pressure in the filter assembly 300 breaking through the box body 310, and extending the service life of the filter assembly 300.
