[0059] The technical solutions of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0060] As shown in Figures 1 to 6 An embodiment of the present application provides a filter assembly for a dishwasher, the dishwasher comprising an inner container, the inner container forming a containing cavity therein, the inner container bottom wall being provided with a drain hole 100, the drain hole 100 being in communication with the containing cavity; the filter assembly comprising: a first filter 200, the first filter 200 being installed in the drain hole 100; the first filter 200 comprising a body 210, the body 210 being provided with a first filter hole 213, the body 210 being provided with a filter cavity 215 in communication with the first filter hole 213, the body 210 being capable of ascending and descending relative to the inner container with the water level change in the drain hole 100.

[0061] The filter assembly provided by the embodiment is used to filter the residues generated in the spraying and cleaning process of the dishwasher.

[0062] Specifically, the dishwasher comprises an inner container, the inner container forming a containing cavity for cleaning and placing tableware, the sewage and residues generated in the cleaning process flowing out of the drain hole 100, the filter assembly being arranged between the containing cavity and the drain hole 100, so as to prevent too much large residues from entering the drain hole 100 and causing the drain hole 100 to be blocked.

[0063] In the embodiment, the filter assembly comprises a first filter 200, which is retractably arranged in the drain hole 100, and is used to intercept some large residues in the first filter 200, so as to avoid causing the drain hole 100 to be blocked. Meanwhile, since the sewage in the drain hole 100 may not be completely drained after washing is completed, when the dishwasher is drained, the first filter 200 is retracted into the drain hole 100, and the residues are left in the filter cavity 215, so that the accommodation cavity is prevented from having an odor.

[0064] In the embodiment, as shown in Figure 5 and Figure 6 , the first filter 200 is provided with a floating block 230, which is used to drive the first filter 200 to ascend and descend; and / or the density of the first filter 200 is less than the density of water.

[0065] In the embodiment, the first filter 200 comprises a plurality of arrangement modes, so as to realize the first filter 200 to ascend and descend in the drain hole 100.

[0066] One is that the first filter 200 is provided with the floating block 230, and the first filter 200 is driven to ascend and descend in the drain hole 100 by the buoyancy of the floating block 230.

[0067] Or the first filter 200 is made of a material with a density less than that of water, so that the first filter 200 can float out of the drain hole 100 due to the density of the first filter 200 being less than the density of water.

[0068] Or the first filter 200 is made of a material with a density less than that of water, and the first filter 200 is provided with the floating block 230, so as to drive the first filter 200 to ascend and descend in the drain hole 100.

[0069] In actual use, the water storage cavity 110 for providing the first filter 200 with buoyancy is arranged in the drain hole 100, which will be described in detail below.

[0070] Optionally, a bending structure such as an elbow can be arranged at the drain hole 100, so as to store water and provide the first filter 200 with buoyancy.

[0071] In the embodiment, the first filter 200 further comprises a blocking part; the blocking part is connected with the body 210; when the body 210 is retracted into the drain hole 100, the blocking part closes the drain hole 100.

[0072] By arranging the blocking part, the drain hole 100 is blocked, so as to prevent the sewage from being humidified and causing the accommodation cavity to have an odor.

[0073] In actual use, when the dishwasher starts to fill water, the first filter member 200 can be extended from the drain hole 100 under the action of buoyancy, and the two ends of the first filter hole 213 on the first filter member 200 are respectively communicated with the filter cavity 215 and the containing cavity, at this time, food residues can be intercepted in the filter cavity 215.

[0074] When the dishwasher drains, the first filter member 200 is retracted into the drain hole 100, at this time, the blocking part blocks the drain hole 100, avoiding moisture returning to the containing cavity, and avoiding odor in the containing cavity.

[0075] In this embodiment, when the dishwasher starts to fill water, at this time, the spray system in the dishwasher for washing tableware is connected with the water source, and starts to supply water to the spray system, at this time, the water source also supplies water to the water storage cavity 110, so that the first filter member 200 can be extended from the drain hole 100. When the dishwasher drains, that is, the dishwasher completes the cleaning of tableware, and discharges the sewage generated in the cleaning process. When the dishwasher drains, the water in the water storage cavity 110 for providing buoyancy for the first filter member 200 will be discharged with the sewage, but due to the large amount of drainage, the water level in the water storage cavity 110 will not change too much, and when the dishwasher finishes draining, the water in the water storage cavity 110 is discharged with the sewage, at this time, the first filter member 200 is retracted into the drain hole 100.

[0076] It can be understood that the filter assembly provided in the embodiment can also be used for bathroom floor drains, and can also be used for washing machines and other equipment.

[0077] As shown in Figure 1 , Figure 4 , Figure 5 and Figure 6 , the body 210 includes opposite first and second end portions 211 and 212, the first end portion 211 is provided with a first filter hole 213, and the blocking part is arranged at the first end portion 211; the first end portion 211 can be extended or retracted from the drain hole 100; when the dishwasher fills water, the first end portion 211 at least partially extends from the drain hole 100, and the containing cavity is communicated with the drain hole 100 through the first filter hole 213; when the dishwasher drains, the first end portion 211 is retracted into the drain hole 100, and the blocking part covers and blocks the drain hole 100.

[0078] The filter assembly provided by the embodiment is characterized in that the first filter hole 213 is arranged at the first end portion 211, and the plugging portion and the first filter hole 213 are arranged at the first end portion 211 to filter residues or seal. When the dishwasher is filled with water, the first end portion 211 at least partially extends out of the drain hole 100. When the dishwasher is drained, sewage flows into the drain hole 100, and the containing cavity is communicated with the drain hole 100 through the first filter hole 213. After the dishwasher is completely drained, the first end portion 211 is retracted into the drain hole 100, and the drain hole 100 is closed by the plugging portion, so that odor and the like cannot return to the containing cavity from the drain hole 100.

[0079] As shown in Figure 1 , Figure 4 , Figure 5 and Figure 6 , the body 210 is in a cylindrical structure, the filter cavity 215 is arranged in the body 210, the first filter hole 213 is arranged on the sidewall of the first end portion 211 and communicated with the drain hole 100, and the end cover 220 arranged at the first end portion 211 is the plugging portion, which can cover and seal the drain hole 100.

[0080] The filter assembly provided by the embodiment is characterized in that the first filter hole 213 is arranged on the sidewall of the first end portion 211, when the first end portion 211 extends out of the drain hole 100, sewage can flow into the drain hole 100 through the first filter hole 213, and the end face of the first end portion 211 is provided with the end cover 220, on one hand, sewage cannot flow into the drain hole 100 from the upper end of the first end portion 211, and on the other hand, the drain hole 100 can be closed after the first end portion 211 is retracted into the drain hole 100.

[0081] As shown in Figure 1 , Figure 4 , Figure 5 and Figure 6 , the edge of the drain hole 100 is provided with the flange 120, and the edge of the end cover 220 is overlapped on the flange 120.

[0082] The filter assembly provided by the embodiment is characterized in that the edge of the end cover 220 is overlapped on the flange 120 to close the drain hole 100. Meanwhile, the flange 120 can prevent the first filter element 200 from being lowered too deep in the drain hole 100 during the lowering process, so that the first filter element 200 is difficult to be taken out or floated up during the next use.

[0083] As shown in Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the body 210 is provided with a filtering cavity 215, and the sidewall of the second end 212 is further provided with a second filtering hole 214 which communicates the drain hole 100 and the filtering cavity 215.

[0084] The filtering assembly provided by the embodiment is used for containing small residues, so as to avoid the residues from entering the drain hole 100.

[0085] Specifically, when the dishwasher is started, the first end 211 extends out of the drain hole 100, and the sewage with residues flows into the drain hole 100, and the residues flow into the filtering cavity 215 along with the sewage. The second filtering hole 214 is used for intercepting small residues in the filtering cavity 215, so as to avoid the residues from flowing into the drain hole 100 along with the sewage, and causing the drain hole 100 to be blocked.

[0086] As shown in Figure 1 , Figure 4 , Figure 5 and Figure 6 , specifically, the area of the first filtering hole 213 is greater than the area of the second filtering hole 214, so as to intercept the residues in the filtering cavity 215.

[0087] As shown in Figure 1 , Figure 4 , Figure 5 and Figure 6 , the body 210 further comprises a connecting portion 216 which is used for connecting the first end 211 and the second end 212. Meanwhile, the sidewall of the connecting portion 216 is also provided with the second filtering hole 214 which is used for intercepting residues.

[0088] The two ends of the connecting portion 216 are connected with the first end 211 and the second end 212 respectively, the first end 211 and the second end 212 are both cylindrical structures, the first end 211 and the second end 212 are coaxially arranged, and the inner diameter of the first end 211 is greater than the inner diameter of the second end 212.

[0089] In the embodiment, preferably, the inner diameter of the first end 211 is slightly smaller than the inner diameter of the drain hole 100, so as to increase the water inlet area of the first filtering piece 200.

[0090] Meanwhile, the inner diameter of the second end 212 is smaller than the inner diameter of the first end 211, and the gap between the second end 212 and the inner wall of the drain hole 100 is large, so that the sewage can flow faster, and the drainage efficiency of the dishwasher is not affected due to slow drainage. Meanwhile, small particle residues can be prevented from being stuck between the outer wall of the second end 212 and the inner wall of the drain hole 100, and the first filtering piece 200 can be prevented from being affected in moving up and down in the drain hole 100.

[0091] AsFigure 5 and Figure 6 The drain hole 100 is provided with a water storage cavity 110, and the body 210 is located in the water storage cavity 110, and the water storage cavity 110 is communicated with a water source.

[0092] In actual use, the water storage cavity 110 is further arranged in the drain hole 100, and a certain amount of water is stored, so that the first filter element 200 can float out of the drain hole 100.

[0093] The water storage cavity 110 is communicated with the water source, and when the dishwasher is filled with water, the water of the water source is first injected into the water storage cavity 110, so that the first filter element 200 can float out of the drain hole 100.

[0094] In the embodiment, the water source can be separately divided into a pipeline communicated with the water storage cavity 110, or can share the same pipeline with a spray arm in the dishwasher, so as to save space.

[0095] In the embodiment, the first filter element 200 is driven to float up and down in the drain hole 100 by arranging the float 230 on the first filter element 200. The float 230 includes various mounting modes.

[0096] The float 230 can be arranged on the second end portion 212. The second end portion 212 is far away from the communication position of the drain hole 100 and the inner container, and is inserted into the water storage cavity 110 the deepest, so that the float 230 is preferably arranged on the second end portion 212. At this time, a small amount of water can be injected into the water storage cavity 110, and the float 230 can drive the first filter element 200 to float out of the drain hole 100.

[0097] The float 230 can also be arranged inside the filter cavity 215. Since the filter cavity 215 is communicated with the drain hole 100, that is, communicated with the water storage cavity 110, when the water storage cavity 110 is filled with water, the filter cavity 215 is also filled with water, and under the action of the float 230, the first filter element 200 is driven to float upward.

[0098] As shown in Figures 4 to 6 The first filter element 200 further includes a mounting frame 240, and the float 230 is mounted on the second end portion 212 through the mounting frame 240, or the float 230 is mounted in the filter cavity 215 through the mounting frame 240.

[0099] It can be understood that in the embodiment, the float 230 can also be connected with the filter element by riveting, gluing and the like, and the same purpose of driving the first filter element 200 to move up and down in the embodiment can be achieved.

[0100] AsFigure 5 and Figure 6 As shown in FIGS. 1-3, the filter assembly further comprises a control member; the control member is configured to control the amount of water in the water storage cavity 110 to be sufficient for the floating of the floating block 230.

[0101] In actual use, in order to avoid the water in the water storage cavity 110 being completely drained, resulting in the first filter member 200 being unable to float, the control member is arranged in the water storage cavity 110, and is configured to control the amount of water in the water storage cavity 110 to be sufficient for the floating of the floating block 230.

[0102] In the embodiment, the control member can be a drainage pump. The drainage pump is in communication with the drain hole 100, and is configured to drain the water in the drain hole 100, and to control the amount of water in the water storage cavity 110 to be sufficient for the floating of the floating block 230.

[0103] It can be understood that in the embodiment, the control member can also be a solenoid valve, which can also achieve the purpose of controlling the amount of water in the water storage cavity 110 to be sufficient for the floating of the floating block 230.

[0104] As shown in FIGS. 1-3, the filter assembly further comprises a second filter member 300; the second filter member 300 is arranged at the outer edge of the drain hole 100, and a third filter hole 310 is arranged in the side wall of the second filter member 300; when the dishwasher is turned on, the first end portion 211 at least partially extends out of the drain hole 100, and the first filter hole 213 and the third filter hole 310 are in communication. Figure 1 、 Figure 3 、 Figure 5 and Figure 6 The filter assembly provided by the embodiment further comprises a second filter member 300, which is configured to perform first filtration on the sewage in the containing cavity, so as to intercept part of large residual in the containing cavity, and avoid the blockage of the drain hole 100 by too large residual.

[0105] As shown in FIGS. 1-3, the area of the third filter hole 310 is smaller than the area of the first filter hole 213, and the area of the third filter hole 310 is larger than the area of the second filter hole 214.

[0106] As shown in FIGS. 1-3, the area of the third filter hole 310 is smaller than the area of the first filter hole 213, and the area of the third filter hole 310 is larger than the area of the second filter hole 214. Figure 1 、 Figure 3 、 Figure 5 and Figure 6 The area of the third filter hole 310 is smaller than the area of the first filter hole 213, and the area of the third filter hole 310 is larger than the area of the second filter hole 214.

[0107] In actual use, when the dish washing machine is filled with water, the water source injects water into the water storage cavity 110, the float 230 drives the first filter 200 to float upwards, the first end 211 extends out of the drain hole 100, and the first filter hole 213 and the third filter hole 310 are communicated. Part of the residues are intercepted in the containing cavity by the third filter hole 310. The remaining part flows into the filter cavity 215 with the water, and the second filter hole 214 intercepts part of the residues in the filter cavity 215. The remaining small residues can be broken by the drain pump and will not block the drain hole 100, the sewer, etc. The user only needs to clean the filter cavity 215 regularly.
