[0047] It should be noted that the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitation, the element defined by the sentence "including a..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0048] The embodiment of the present application provides a separator which can be applied to cleaning equipment such as washing machines, dishwashers, fruit and vegetable cleaning machines, etc. It should be noted that the application scenario type of the embodiment of the present application does not limit the separator of the embodiment of the present application.

[0049] The separator is applied to a dishwasher as an example. The separator in the embodiment of the present application can separate mixed fluid with solid and liquid into separate liquid or separate solid.

[0050] The embodiment of the present application provides a separator 100, as shown in Figure 1 and Figure 2 The separator 100 includes a water cup 1, a filtering device 2, a second filtering assembly 3 and a water outlet 4. Wherein, Figure 1 As shown in FIG. 1, it is a perspective view of the separator 100 of the embodiment of the present application, Figure 2An exploded view of the separator 100 is shown. The water cup 1 is internally provided with a water inlet cavity 11, which is open at one end in the vertical direction. It should be noted that the vertical direction herein refers to the absolute coordinate system. The water inlet cavity 11 is connected to the outside of the separator 100. In the case of the separator 100 being applied to a dishwasher, the water inlet cavity 11 can be used to receive fluid to be separated in the dishwasher. The fluid can be introduced into the water inlet cavity 11 through the upper end of the water cup 1.

[0051] As shown in Figure 1 , the filter device 2 is connected to the water cup 1. The filter device 2 is provided with a first water outlet 21. After the fluid is introduced into the water inlet cavity 11 through the upper end of the water cup 1, the fluid in the water inlet cavity 11 can flow into the filter device 2. The filter device 2 is used to guide the fluid in the water inlet cavity 11 to spiral motion, so as to separate at least part of the liquid in the fluid to the first water outlet 21. It should be noted that the spiral motion refers to the fluid entering the filter device 2 from the water inlet cavity 11, which can rotate spirally in the first direction. The fluid in the spiral motion will be subjected to centrifugal force. Since the density of the solid in the fluid is greater than that of the liquid, the centrifugal force acting on the solid in the fluid is greater than that acting on the liquid, so that most of the solid and liquid in the fluid can be separated in the filter device 2. The first water outlet 21 in the filter device 2 is used to guide the liquid separated in the filter device 2 to flow out.

[0052] As shown in Figure 1 and Figure 2 , the second filter assembly 3 is arranged outside the water cup 1. It should be noted that the outside of the water cup 1 refers to the second filter assembly 3 not having a positional overlapping relationship with the water cup 1.

[0053] In the embodiment of the present application, the second filter assembly 3 is connected to the filter device 2. The filter device 2 introduces the unfiltered fluid into the second filter assembly 3. That is, the liquid is filtered out of the fluid in the filter device 2 and guided to flow out of the first water outlet 21. The remaining solid and liquid are introduced into the second filter assembly 3 for filtration. The second filter assembly 3 is provided with a second water outlet 31. The second filter assembly 3 filters the fluid introduced from the filter device 2, retains all the solid in the second filter assembly 3, and guides the liquid in the fluid to flow out of the second water outlet 31.

[0054] As shown in Figure 2 , the present application is provided with a water outlet member 4. The water outlet member 4 is used to combine the liquid of the first water outlet 21 and the second water outlet 31, and guide the liquid to flow out of the third water outlet 42 of the water outlet member 4 for recycling of the cleaning equipment. Among them, Figure 10 , the third water outlet 42 of the water outlet member 4 is connected to the second water outlet 31 of the second filter assembly 3. The third water outlet 42 of the water outlet member 4 is connected to the first water outlet 21 of the filter device 2. The third water outlet 42 of the water outlet member 4 is connected to the second water outlet 31 of the second filter assembly 3. The third water outlet 42 of the water outlet member 4 is connected to the first water outlet 21 of the filter device 2. Figure 7Figure 5 is a cross-sectional view of the E-E section in Figure 4, which shows the connection between the water outlet 4 and the first water outlet 21 and the second water outlet 31, in combination with Figure 10 As shown in Figure 5, the water outlet 4 is internally provided with a water outlet passage 41, which is connected to the first water outlet 21 and the second water outlet 31. The water outlet 4 is also provided with a third water outlet 42, which is connected to the water outlet passage 41. The water outlet 4 can be understood as a three-way pipe, that is, the water outlet 4 connects the first water outlet 21 and the second water outlet 31 through the water outlet passage 41. The filtered liquid in the filter device 2 can be introduced from the first water outlet 21 to the water outlet passage 41, and the filtered liquid in the second filter assembly 3 can be introduced from the second water outlet 31 to the water outlet passage 41. The liquid introduced from the first water outlet 21 and the second water outlet 31 converges in the water outlet passage 41 and is then introduced from the third water outlet 42.

[0055] The embodiment of the present application provides a separator and a cleaning device, the separator comprises a water cup, a filtering device, a second filtering assembly and a water outlet, the water cup is internally provided with a water inlet cavity, the water inlet cavity is communicated with the outside of the separator, the filtering device is connected with the water cup, the filtering device is provided with a first water outlet, the filtering device is internally provided with a cyclone channel and a first filtering screen which are arranged to rotate around a first direction, the first filtering screen guides liquid passing through the cyclone channel into the first filtering screen, and the first water outlet is communicated with the inside of the first filtering screen; the second filtering assembly is arranged outside the water cup and connected with the filtering device, the second filtering assembly is internally provided with a second filtering screen, the second filtering assembly is provided with a second water outlet which is communicated with the outside of the second filtering screen, and the second filtering screen guides liquid introduced from the filtering device to the second water outlet; the water outlet guides liquid introduced from the first water outlet and the second water outlet to be discharged from a third water outlet. The filtering device and the second filtering assembly are arranged, the filtering device is internally provided with the cyclone channel and the first filtering screen which rotate around the first direction, mixed fluid mixed with solid and liquid enters the cyclone channel, under the action of inertial centrifugal force, solid with a density far greater than that of liquid can move in a radial direction away from the first filtering screen, solid with a density slightly greater than that of liquid cannot be separated from liquid under the action of inertial centrifugal force, but only liquid can enter the first filtering screen under the blockage of the first filtering screen, part of liquid remaining outside the first filtering screen can drive solid to continuously flow to the second filtering assembly, the second filtering screen can block solid inside, liquid flows from the inside of the second filtering screen to the second water outlet outside the second filtering screen, the second filtering assembly is arranged outside the water cup, so that the second filtering assembly is independently arranged with the water cup, the design size and structure of the water cup are not limited by the second filtering assembly, the design structure of the water cup is simplified, the water cup is not nested with other components, the manufacturing and assembly difficulty of the separator is reduced, the design size of the water cup is more flexible, the water cup is beneficial to flexibly control the water inlet amount, in the case that the size of the water cup is designed to be small, the fluid speed introduced into the separator is reduced, so that the water saving effect is achieved. Liquid filtered by the filtering device and the second filtering assembly is converged and discharged by the water outlet, which is beneficial to increase the flow of discharged fluid and simplify the structure of the separator.

[0056] In some embodiments, as shown in Figure 3 Fig. 2, the filtering device 2 comprises a cyclone assembly 210 and a first filtering screen 22. In combination with Figure 4 and Figure 5 Fig. 2, the cyclone assembly 210 is internally provided with a cyclone channel 211 extending in a horizontal direction, and the first filtering screen 22 is at least partially arranged in the cyclone assembly 210, the cyclone assembly 210 is internally provided with a first direction (D1) around which the cyclone channel 211 and the first filtering screen 22 rotate, and the first filtering screen 22 is arranged to be perpendicular to the first direction (D1). Figure 5The cyclone passage 211 is arranged in a rotating manner, which means that the fluid can form a rotating flow when passing through the cyclone passage 211, instead of only moving in a straight line. The cyclone passage 211 is arranged in a first direction (indicated by the arrow in the vertical direction of the paper) and a second direction (indicated by the arrow in the horizontal direction of the paper) in a spaced manner. Figure 5 The cyclone passage 211 is arranged in a rotating manner, which means that the fluid can form a rotating flow when passing through the cyclone passage 211, instead of only moving in a straight line. The cyclone passage 211 is arranged in a first direction (indicated by the arrow in the vertical direction of the paper) and a second direction (indicated by the arrow in the horizontal direction of the paper) in a spaced manner. Figure 8 Figure 5 The arrow in the middle direction indicates the movement direction of the fluid. The water inlet cavity 11 is connected to the cyclone inlet 2122, which is used to guide the fluid to be separated into the cyclone passage 211. In combination with the cyclone passage 211, the cyclone inlet 2122 can separate the solid or solid-liquid mixture in the cyclone passage 211. Figure 8 The arrow in the middle direction indicates the movement direction of the fluid. The water inlet cavity 11 is connected to the cyclone inlet 2122, which is used to guide the fluid to be separated into the cyclone passage 211. In combination with the cyclone passage 211, the cyclone inlet 2122 can separate the solid or solid-liquid mixture in the cyclone passage 211. Figure 8 The left and right directions can be used to indicate the first direction.

[0057] In the embodiment of the present application, the area of the first filter screen 22 is larger than the area of the second filter screen 32. It should be noted that the first filter screen 22 can substantially form a cylindrical structure, and the area of the first filter screen 22 represents the lateral area of the cylinder formed by the first filter screen 22. The second filter screen 32 also substantially forms a cylindrical structure, and the area of the second filter screen 32 represents the lateral area of the cylinder formed by the second filter screen 32. The area can be used to represent the water passing capacity of the first filter screen or the second filter screen. The larger the area, the greater the water passing capacity. In the embodiment of the present application, the area of the first filter screen 22 is larger than the area of the second filter screen 32, and the number of first through holes that can be arranged on the first filter screen 22 is greater than the number of second through holes that can be arranged on the second filter screen 32. Therefore, the water passing capacity of the first filter screen is greater than the water passing capacity of the second filter screen. In addition, the first filter screen 22 is closer to the water inlet cavity 11 than the second filter screen 32, so the resistance of the liquid guided out of the first filter screen 22 is smaller than the resistance of the liquid guided out of the second filter screen 32. Therefore, most of the liquid passes through the first filter screen 22 and is guided out of the first water outlet 21, and the remaining small part of the liquid carries the solid blocked outside the first filter screen 22 and is flushed to the second filter assembly. The remaining small part of the liquid passes through the second filter screen and flows to the second water outlet 31.

[0058] As Figure 5 ​As shown, the cyclone passage 211 is connected to the bottom of the water inlet cavity 11. It should be noted that the bottom means the lower part of the water inlet cavity 11 in the absolute coordinate system, that is, the cyclone inlet 2122 is connected to the lower end of the water inlet cavity 11. It can be understood that the distance from the cyclone inlet 2122 to the bottom of the water inlet cavity 11 is less than or equal to a set value, which can be zero. In the embodiment of the present application, the cyclone passage is connected to the bottom of the water inlet cavity. In the case of a small amount of water in the water inlet cavity, the cyclone inlet can also guide the fluid at the bottom of the water inlet cavity into the cyclone passage, thereby reducing the water inlet height of the cyclone passage, preventing air in the water inlet cavity from entering the cyclone passage through the cyclone inlet, and preventing the cyclone passage from being easily sucked.

[0059] As shown in Figure 7 and Figure 8 The first filter screen 22 is arranged in the cyclone passage 211, and the first filter screen 22 is internally provided with a first water passage 221 extending in the horizontal direction. The first filter screen 22 is arranged at least in the cyclone passage 211, which means that the first filter screen 22 can be completely arranged in the cyclone passage 211 or partially arranged in the cyclone passage 211 and partially arranged outside the cyclone passage 211. The first filter screen 22 is internally provided with a first water passage 221 extending in the first direction, and the extension direction of the first water passage 221 represents the maximum dimension direction (length direction) of the first water passage 221. The first water passage 221 is in communication with the cyclone passage 211, and the first filter screen 22 is used to guide the liquid passing through the cyclone passage 211 into the first water passage 221 and block the solid passing through the cyclone passage 211, so that the solid passing through the cyclone passage 211 is left between the first filter screen 22 and the cyclone assembly 210. As shown in Figure 8 The first water outlet 21 is arranged at one end of the first water passage 221 in the horizontal direction, and the first water outlet 21 is used to guide the liquid in the first water passage 221 out. In the case that the separator 100 is applied to a dishwasher, the liquid guided out of the first water outlet 21 can be recycled by the dishwasher.

[0060] The embodiment of the present application sets the cyclone channel to rotate around the first direction, sets the first filter screen in the cyclone channel, and the mixed fluid mixed with solid and liquid enters the cyclone channel through the cyclone inlet. Under the action of the inertial centrifugal force, the solid with density far greater than the liquid can move in the radial direction away from the first filter screen, and the solid with density slightly greater than the liquid cannot be separated from the liquid by the action of the inertial centrifugal force, but under the blockage of the first filter screen, only the liquid can enter the first water passage, and the liquid remaining between the first filter screen and the cyclone assembly can drive the solid to continue to flow to the cyclone outlet, and the solid and a small amount of liquid are discharged to the second filter assembly through the cyclone outlet at one time, which is beneficial to improve the efficiency of liquid separation, and the solid will not stay in the cyclone channel to block the first filter screen, which is beneficial to improve the flow of the liquid in the first water passage and facilitate the recycling of the liquid.

[0061] In some embodiments, as shown in Figure 3 , Figure 5 and Figure 8 , the cyclone assembly 210 includes a cyclone volute 212 and a cyclone shell 213. As shown in Figure 5 , the cyclone volute 212 forms a first cyclone channel 2121 inside which rotates around the first direction (the vertical paper surface direction shown in Figure 5 ) in the circumferential direction. The first cyclone channel 2121 is provided with a cyclone inlet 2122 in the circumferential direction. It should be noted that the circumferential direction is the direction around the first direction. The cyclone shell 213 forms a second cyclone channel 2131 inside which extends along the first direction (the left-right direction shown in Figure 8 ). The extension direction of the second cyclone channel 2131 represents the maximum dimension direction of the second cyclone channel 2131. The second cyclone channel 2131 is in communication with the first cyclone channel 2121 at one end (the right end shown in Figure 8 ) of the first direction, and the other end of the second cyclone channel 2131 is Figure 8The left end of the second swirling channel 2121 (as shown) is provided with a swirling outlet 2132. It should be noted that the other end of the second swirling channel 2131 represents the position of the second swirling channel 2131 away from the first swirling channel 2121. The swirling outlet 2132 is not located at the leftmost end of the second swirling channel 2131 in the first direction; the swirling outlet 2132 can also be located at a position less than a certain range from the leftmost end. In this embodiment of the invention, the first swirling channel 2121 and the second swirling channel 2131 together form the swirling channel 211. By setting a first vortex channel rotating around a first direction inside the vortex casing, the fluid can achieve solid-liquid separation by inertial centrifugal force after passing through the first vortex channel, allowing most of the liquid to enter the first water passage channel. By setting a second vortex channel extending along the first direction inside the vortex casing, since both the first filter screen and the second vortex channel extend along the first direction, and the direction of liquid flow in the first vortex channel is different, the liquid direction will change after entering the second vortex channel, which plays a rectifying role. Some of the liquid can enter the first water passage channel, and the liquid in the first water passage channel can be discharged through the first outlet for recycling; the other part of the liquid can continue to move in the second vortex channel along the first direction, thereby driving the solids in the second vortex channel to the vortex outlet to achieve solid removal.

[0062] In some embodiments, such as Figure 8 As shown, the filter device also includes an inner cylinder 223. A first water passage 221 is formed inside the first filter screen 22, and the first water passage 221 flows along a first direction (…). Figure 8 Extending in the left-right direction (as shown), in this embodiment of the invention, the first filter screen 22 extends from the first vortex channel 2121 to the second vortex channel 2131 along the first direction. That is, the orthographic projection of the first filter screen 22 in the first direction overlaps with both the first vortex channel 2121 and the second vortex channel 2131. The first water passage channel 221 is connected to the vortex channel 211. Specifically, in some embodiments, the first filter screen 22 is provided with a plurality of first through holes, which connect the first water passage channel 221 and the vortex channel 211. Due to the restriction of the first through holes, the liquid in the vortex channel 211 can flow through the first through holes into the first water passage channel 221, but the solids in the vortex channel 211 cannot pass through the first through holes and can only be blocked by the first through holes between the first filter screen 22 and the vortex assembly.

[0063] In some embodiments, the diameter of the first through hole is greater than or equal to 0.1 mm and less than or equal to 0.4 mm, for example, the diameter of the first through hole can be set to 0.3 mm, wherein the first through hole can be set as a cylindrical hole, and the diameter of the first through hole represents the diameter of the circle. Of course, the cross section of the first through hole can also be set as an irregular shape, for example, the cross section of the first through hole can be set as an ellipse, a triangle, a square and the like. When the cross section of the first through hole is set as an irregular shape, the diameter of the first through hole can be represented by the diameter of the standard circle with equal area. The embodiments of the present application set the diameter of the first through hole within a certain range, and the first through hole can filter out 99% of the solids in the fluid, which can be regarded as the first filter screen almost completely separates the solids and liquids in the fluid.

[0064] As shown in Figure 8 , the embodiments of the present application extend the first filter screen 22 from the first cyclone passage 2121 into the second cyclone passage 2131 in the first direction. The fluid mixed with solids and liquids enters the first cyclone passage 2121 from the cyclone inlet 2122. Part of the liquid can pass through the first filter screen 22 in the first cyclone passage 2121 and enter the first water passage 221. The remaining fluid can continue to flow into the second cyclone passage 2131. After the fluid enters the second cyclone passage 2131, part of the liquid passes through the first filter screen 22 in the second cyclone passage 2131 and enters the first water passage 221. The remaining small amount of liquid can drive the solids to continue to move in the first direction to drive the solids to be discharged from the cyclone outlet 2132, reducing the risk of solids blocking the first filter screen 22 and improving the flow of liquid in the first water passage. The first filter screen extends into the first cyclone passage, which can improve the efficiency of fluid filtration. The first filter screen extends into the second cyclone passage, and the extension direction of the first filter screen in the second cyclone passage is inconsistent with the original flow direction of the fluid in the first cyclone passage. The first filter screen in the second cyclone passage can function as a flow regulator, greatly reducing the rotational flow intensity of the liquid entering the first water passage, greatly reducing the resistance of the entire separator, and being conducive to improving the stability of the structure of the separator. Moreover, the length of the first filter screen is longer, which is conducive to improving the efficiency of filtration.

[0065] As shown in Figure 8 , the inner cylinder 223 is hollow inside and arranged in the first water passage 221. The hollow inside of the inner cylinder 223 can be understood as that the inner cylinder 223 is open at both ends in the first direction. One end of the inner cylinder 223 in the first direction is in communication with the first water outlet 21, and the other end of the inner cylinder 223 in the first direction is in communication with the first water passage 221. The inner cylinder 223 is arranged through in the first direction. One end (the right end as shown in Figure 8 ) of the inner cylinder 223 in the first direction is fixedly connected with the inner wall surface of the cyclone volute 212 and is in communication with the first water outlet 21, and the other end of the inner cylinder 223 in the first direction is in communication with the first water passage 221. Figure 7As shown, the inner cylinder 223 is located at the other end in the first direction ( Figure 5 The left end (shown) is connected to the first water passage 221. The first outlet 21 can be disposed through one end of the vortex casing 212 in the first direction, and the inner cylinder 223 can cover the entire first outlet 21, ensuring that the liquid in the first water passage 221 can only flow to the first outlet 21 through the interior of the inner cylinder 223. This embodiment of the invention, by setting an inner cylinder within the first water passage, helps to rectify the liquid flowing out to the first outlet, thereby improving the consistency of the liquid's movement direction.

[0066] In some embodiments, such as Figure 5 As shown, the width of the first swirl channel 2121 narrows along the direction of fluid flow. Figure 8 The direction indicated by the middle arrow represents the direction of fluid flow. It should be noted that the fluid flow direction within the first vortex channel 2121 is from entering the first vortex channel 2121 at the vortex inlet 2122, and then spiraling along the first vortex channel 2121. In this embodiment of the invention, by gradually narrowing the width of the first vortex channel, the direction of fluid movement is altered, causing the fluid to spiral and generating inertial centrifugal force in the solids within the fluid during its movement. According to fluid dynamics principles, narrowing the width of the first vortex channel increases the fluid velocity, which is beneficial for improving the filtration efficiency of the separator.

[0067] like Figure 8 As shown, the second vortex channel 2131 includes a first sub-cavity 2133 and a second sub-cavity 2134 separated in the vertical direction. It should be noted that the separation indicates that the first sub-cavity 2133 and the second sub-cavity 2134 are independent of each other in the vertical direction, but not completely closed. The first sub-cavity 2133 and the second sub-cavity 2134 can be connected at one end in the first direction, for example... Figure 8 In the illustrated embodiment, the first sub-cavity 2133 and the second sub-cavity 2134 are located at the ends of the first vortex channel 2121 in a first direction ( Figure 8 As shown on the left end, the first filter screen 22 is partially located within the first sub-cavity 2133. The first sub-cavity 2133 is connected to the first vortex channel 2121 and the second sub-cavity 2134 at its two ends in the first direction, respectively. Figure 8 As shown, the fluid entering the first swirling channel 2121 will continue forward along the first sub-cavity 2133 ( Figure 3As shown (flowing to the left), some liquid enters the first water passage 221, while the remaining liquid carries the solids to the second sub-cavity 2134. The second sub-cavity 2134 is provided with a vortex outlet 2132, through which the solids and a small amount of liquid can be discharged. This embodiment of the invention, by dividing the second vortex channel into a first and a second sub-cavity in the vertical direction, allows the fluid mixed with solids and liquids to enter the second sub-cavity from the first sub-cavity and then be discharged through the vortex outlet. This helps reduce the risk of solids flowing back into the first vortex channel and also allows for a lower vortex outlet height, improving fluid discharge efficiency.

[0068] In some embodiments, combined with Figure 8 and Figure 8 As shown, the first filter screen 22 also includes a filter screen driving device 224 and a first support assembly 225. The filter screen driving device 224 is connected to the first filter screen 22 and is used to drive the first filter screen 22 around a first direction ( Figure 3 (as shown in the left and right directions) Rotation. It should be noted that the frequency and speed of the rotation of the filter drive device 224 are not limited in this embodiment of the invention, as long as the filter drive device 224 can drive the first filter screen 22 to rotate. During the process of the liquid in the vortex channel entering the first water passage channel, the solids in the vortex channel are blocked outside the first water passage channel by the first filter screen. Some solids will adhere to the first filter screen due to the influence of the water flow or the size of the first through hole. In this embodiment of the invention, the filter drive device drives the first filter screen to rotate, and the solids on the first filter screen will detach from the surface of the first filter screen under the action of inertia, reducing the risk of solids adhering to the first filter screen, and improving the water passage efficiency of the first filter screen. It can also realize the self-cleaning of the first filter screen, eliminating the need for washing and improving the user's operation convenience.

[0069] Combination Figure 8 and Figure 8 As shown, the first support assembly 225 is fixed to the swirl assembly (see reference). Figure 8 Regarding the vortex volute 212 and vortex outer shell 213 shown, and the first filter screen 22, it should be noted that the embodiments of the present invention do not limit the fixing method of the first support assembly 225. The first support assembly 225 can be directly fixed to the vortex assembly, or it can be indirectly fixed to the vortex assembly through other components. However, regardless of the fixing method used, it is sufficient that the first support assembly 225 remains stationary relative to the vortex channel. Figure 8 As shown, the first support assembly 225 is at least partially in contact with the first filter screen 22. The portion of the first support assembly 225 that contacts the first filter screen 22 extends in a spiral direction and has a spirally wound structure; it is not a straight-line contact, nor is it a surface contact.

[0070] In the process of filtering fluid by the filtering device, a small amount of pollutants can still adhere to the first filter screen. The embodiments of the present application set the first support assembly. In the process of rotating the first filter screen 22, the first support assembly 225 is stationary relative to the cyclone assembly, so the first filter screen 22 rotates relative to the first support assembly 225. The contact between the first support assembly 225 and the first filter screen 22 enables the horizontal support assembly to scrape off the pollutants on the first filter screen. In addition, the first support assembly 225 is at least partially in helical contact with the first filter screen 22. The fluid in the filtering device also moves helically in the first direction. The portion of the helical contact is approximately the same as the movement direction of the fluid in the filtering device, which is conducive to reducing the interference of the first support assembly on the cyclone field in the cyclone passage and reducing the risk of blocking the passage in the cyclone passage.

[0071] In some embodiments, as shown in Figure 8 The first filter screen 22 further includes a flow guide 226. The flow guide 226 is arranged in the first water passage 221 and connected with the filter screen driving device 224. It should be noted that the flow guide 226 can be fixedly connected with the filter screen driving device 224. The embodiments of the present application do not limit the specific connection form of the flow guide 226 and the filter screen driving device 224. For example, the flow guide 226 can be permanently connected with the filter screen driving device 224 by welding or one-piece forming. For another example, the flow guide 226 can be detachably connected with the filter screen driving device 224 by clamping or other ways, as long as the rotation of the filter screen driving device 224 can drive the rotation of the flow guide 226.

[0072] As shown in Figure 8 The cross-sectional area of the flow guide 226 gradually increases from one end close to the cyclone volute 212 to the end connected with the filter screen driving device 224. The cross section of the flow guide 226 is perpendicular to the first direction, and the cross-sectional area can be understood as the area of the cross section of the flow guide 226. In some embodiments, the flow guide 226 can be set as a conical body, so the cross section of the flow guide 226 is circular. Therefore, the change trend of the cross-sectional area of the flow guide 226 can be represented by the change of the diameter of the flow guide 226 in the cross section, as shown in Figure 9 Figures 12-15 ​As shown, the diameter of the guide member 226 gradually decreases from left to right along the first direction. During the rotation of the guide member 226, the liquid in the second vortex channel 2131 is stirred by the guide member 226 and flows along the surface of the guide member 226 in a direction away from the center of the guide member 226. That is, the liquid flows from right to left along the first direction. When the liquid flows close to the guide member 226, the liquid in the first water passage 221 flows along the surface of the guide member 226 towards the first sub-cavity 2133. The liquid flowing towards the first sub-cavity 2133 will also drive the solid in the first sub-cavity 2133 to flow towards the second sub-cavity 2134. This is beneficial for the liquid to guide the solid in the first sub-cavity to the second sub-cavity, thereby improving the separation efficiency of the separator.

[0073] In some embodiments, such as Figure 8 As shown, the first support assembly 225 includes a mounting bracket 2251. The mounting bracket 2251 is connected to the swirl assembly 210 near the swirl channel 211 (in conjunction with...). Figure 12 (as shown) one side. As... Figure 3 As shown, the flexible component 2252 is fixed to the fixed frame 2251. The flexible component 2252 is spirally arranged around a first direction and contacts the first filter screen 22. It should be noted that the flexible component 2252 refers to a component made of a material with low hardness. The hardness of the flexible component 2252 is less than that of the fixed frame 2251. In this embodiment of the invention, the flexible component can be made of rubber or a brush, etc. By making the flexible component with a material with low hardness, it is beneficial to improve the fit between the flexible component 2252 and the first filter screen 22. This not only improves the cleaning efficiency of the first filter screen 22 but also reduces the resistance of the first filter screen to the flexible component, thereby reducing the energy consumption for driving the rotation of the first filter screen. Furthermore, using a flexible component with low hardness is beneficial for adapting to the first filter screen, which may have low processing precision or roundness, so that the flexible component contacts the first filter screen as much as possible, thereby improving the cleanliness of the first filter screen. In this embodiment of the invention, the fixed frame 2251 provides support and fixation for the flexible component 2252.

[0074] Among them, combined Figure 5 and Figure 3 As shown, the swirling channel 211 is at least partially spirally arranged around the first direction, and the spiral direction of the flexible member 2252 is the same as the spiral direction of the swirling channel. Figure 3 (The direction of the dashed line shown is consistent with the direction of the vortex channel 211.) The spiral direction of the vortex channel 211 can be referenced... Figure 13In the direction indicated by the dotted arrow, the embodiment of the present application defines the spiral direction of the cyclone passage 211 as the counterclockwise direction, and correspondingly, the spiral direction of the flexible member 2252 is consistent with the spiral direction of the cyclone passage 211, that is, the spiral direction of the flexible member 2252 is also counterclockwise. The embodiment of the present application sets the spiral direction of the cyclone passage 211 consistent with the spiral direction of the flexible member 2252, so that the movement direction of the fluid entering the cyclone passage 211 from the cyclone inlet is consistent with the spiral direction of the flexible member, which is conducive to reducing the resistance of the flexible member to the fluid movement, thereby improving the effect of the spiral movement of the fluid in the cyclone passage. And in the case of reducing the resistance of the flexible member, even if the thickness of the flexible member is increased, it will not have a greater impact on the fluid in the cyclone passage.

[0075] In some embodiments, as shown in Figure 14 and Figure 14 , the thickness L1 of the flexible member 2252 in the radial direction is greater than the minimum distance L2 between the first filter screen 22 and the fixed frame 2251. Wherein, Figure 12 represents a cross-sectional view of the first support assembly, wherein the first support assembly can be generally circular in cross-section, the center of the circle is generally the center of the first filter screen 22, and the direction of the straight line passing through the center is the radial direction of the first support assembly. It should be noted that the first filter screen 22 has a certain machining size error, so the distance between the fixed frame 2251 and the first filter screen 22 is not necessarily a fixed value. The embodiment of the present application sets the thickness of the flexible member 2252 in the radial direction to be greater than the minimum distance between the fixed frame and the first filter screen, so that the flexible member can contact as many positions of the first filter screen as possible, thereby improving the cleaning degree of the self-cleaning of the first filter screen.

[0076] As shown in Figure 12 , the fixed frame 2251 includes a first support 2253. The first support 2253 is fixed to the inner side of the cyclone assembly 210, the first support 2253 is spirally arranged around the first direction, and the flexible member 2252 is connected with the first support 2253. The extension direction of the first support 2253 is consistent with the extension direction of the flexible member 2252, and the first support 2253 can fix the flexible member 2252. The embodiment of the present application spirally arranges the first support around the first direction, which can stably fix the flexible member and is also conducive to reducing the obstruction of the first support to the fluid in the cyclone passage.

[0077] In some embodiments, as shown in Figure 12As shown, the fixing frame 2251 further comprises a plurality of second supports 2254. The plurality of second supports 2254 are arranged in a ring shape, the plurality of second supports 2254 are spaced apart in the first direction, and the plurality of second supports 2254 are all connected with the first support 2253, and at least part of the second supports 2254 are all sleeved outside the first filter screen 22. The number of the second supports 2254 can be one, two, three, four, etc. Figure 12 In the embodiment shown, the second supports 2254 are provided as two, the two second supports 2254 are respectively connected with the two ends of the first support 2253 in the first direction, and the two second supports 2254 are both sleeved outside the first filter screen 22. The second supports 2254 can play a positioning role on the first filter screen, so as to improve the stability of the movement of the first filter screen.

[0078] In some embodiments, as shown in Figure 2 As shown, the fixing frame 2251 further comprises a third support 2255. The third support 2255 extends along the first direction, and the third support 2255 is connected with the plurality of second supports 2254 and the first support 2253. The third support connecting the first support and the second support and extending along the first direction can improve the structural strength of the first support and the second support, thereby improving the structural stability of the fixing frame.

[0079] In some embodiments, as shown in Figure 9 and Figure 9 As shown, the second filter assembly 3 comprises a first housing 37 and a second filter screen 32. As shown, Figure 8 The first housing 37 is internally provided with a water outlet cavity 311 extending along a vertical direction. It should be noted that the vertical direction represents the up-down direction in the absolute coordinate system. The second filter screen 32 is arranged in the water outlet cavity 311, and the second filter screen 32 is internally provided with a containing cavity 321 communicating with the water outlet cavity 311. As shown, Figure 9 The containing cavity 321 communicates with the cyclone outlet 2132 and the water outlet cavity 311. The second filter screen 32 is used to guide the liquid between the first filter screen 22 and the cyclone assembly 210 to the water outlet cavity 311, and to leave the solid between the first filter screen 22 and the cyclone assembly 210 in the containing cavity 321. The containing cavity 321 can collect the solid in the fluid, so as to facilitate the centralized discharge of the solid. The liquid in the water outlet cavity 311 can be introduced into the dishwasher again for recycling.

[0080] The second filter screen 32 extends along the vertical direction. It should be noted that the extension direction of the second filter screen 32 in the normal use state is parallel to the vertical direction. The second filter screen 32 can be provided as a structure penetrating in the vertical direction, and at least one end of the second filter screen 32 is open in the vertical direction. Figure 8As shown, the lower end of the second filter screen 32 is open, and the lower end of the second filter screen 32 is connected to the vortex outlet 2132 (refer to...). Figure 2 (As shown) The fluid exiting from the vortex outlet 2132 can enter the receiving cavity 321 from the lower end of the second filter screen 32. The upper end of the second filter screen 32 in the vertical direction abuts against the inner wall of the first housing 37. It should be noted that the abutment between the second filter screen 32 and the inner wall of the first housing 37 indicates that there is no fixed connection between the second filter screen 32 and the first housing 37, and that the second filter screen 32 and the first housing 37 can be in close contact. This allows the second filter screen 32 to move relative to the first housing 37 without making the gap between the second filter screen 32 and the first housing 37 too large, thereby reducing the risk of solids in the receiving cavity 321 flowing into the outlet cavity 311 through the gap. Furthermore, the second filter screen extends vertically, which can share the function of collecting solid residues with the first filter screen, which helps to reduce the structural size of the first filter screen in the horizontal direction and improves the overall structural compactness of the separator.

[0081] In some embodiments, such as Figure 9 and Figure 9 As shown, the second filter assembly 3 also includes a second support assembly 33 and a support drive device 34. The second support assembly 33 is movably disposed within the receiving cavity 321. The second support assembly 33 includes a scraper 331, which contacts the inner side of the second filter screen 32. The extension direction of the scraper 331 forms a predetermined angle θ with the vertical direction. It should be noted that the extension direction of the scraper 331 represents the direction of its maximum dimension, which can be understood as the length direction of the scraper. The length direction of the scraper 331 forms a predetermined angle θ with the vertical direction. The support drive device 34 is connected to the second support assembly 33 and is used to drive the scraper 331 to rotate relative to the second filter screen 32. The tilt direction of the scraper 331 is consistent with the direction in which the support drive device 34 drives the scraper 331 to rotate, for example... Figure 9 As shown, the scraper 331 can be understood as extending in a counterclockwise direction. The left end of the scraper 331 is closer to the top of the second filter screen 32 than the right end. The bracket drive device 34 drives the scraper 331 to rotate counterclockwise, so that during the rotation of the scraper 331, the scraper 331 can provide both circumferential force and downward force to the solid, which is beneficial to improving the settling speed of the solid in the cavity, thereby improving the efficiency of solid impurity removal.

[0082] In some embodiments, such as Figure 9 As shown, one end of the scraper 331 ( Figure 9 The upper end of the scraper 331 is close to one end of the second filter 32 in the vertical direction, and the other end of the scraper 331 is close to the other end of the second filter 32 in the vertical direction. Figure 9It is to be noted that the closer distance is the distance between the two ends of the scraper 331 and the two ends of the second filter screen 32 in the vertical direction. The embodiment of the present application makes the rotation of the scraper contact as many positions of the second filter screen as possible by making the two ends of the scraper close to the two ends of the second filter screen, thereby increasing the cleaning area of the second filter screen and reducing the risk of clogging of the residues on the second filter screen as much as possible.

[0083] In some embodiments, as shown in Figure 10 The angle θ is greater than or equal to 30 degrees and less than or equal to 60 degrees. That is, the angle between the scraper 331 and the setting direction is greater than or equal to 30 degrees and less than or equal to 60 degrees. The angle θ can be 30 degrees, 40 degrees, 45 degrees, 50 degrees, 60 degrees, etc. The embodiment of the present application limits the setting angle of the scraper within a certain range, which can improve the speed of solid settling in the containing cavity and reduce the interference effect on the flow of liquid in the containing cavity, thereby improving the efficiency of liquid flowing from the containing cavity to the water outlet cavity.

[0084] In some embodiments, as shown in Figure 17 The scraper 331 includes a mounting member 3311 and a flexible member 2252. The hardness of the flexible member 2252 is less than that of the mounting member 3311. The mounting member 3311 extends along the setting angle, and the flexible member 2252 is arranged along the extension direction of the mounting member 3311 and is fixed to the side of the mounting member 3311 close to the second filter screen 32. The flexible member 2252 is a component composed of a material with lower hardness. The flexible member in the embodiment of the present application can be made of rubber or a brush. By making the flexible member from a material with lower hardness, the adhesion of the flexible member 2252 to the second filter screen 32 can be improved, which can improve the cleaning efficiency of the second filter screen 32 and reduce the resistance of the second filter screen 32 to the flexible member, thereby reducing the energy consumption for driving the second filter screen 32 to rotate. Moreover, the flexible member with lower hardness can adapt to the second filter screen 32 with low machining precision or roundness, so that the flexible member can contact the second filter screen 32 as much as possible, thereby improving the cleanliness of the second filter screen 32. The mounting member 3311 supports and fixes the flexible member 2252.

[0085] As shown in Figure 18 and Figure 18 The thickness L3 of the flexible member 2252 in the radial direction is greater than the minimum distance L4 between the mounting member 3311 and the second filter screen 32. In some embodiments, as shown in Figure 19The second bracket assembly is a cross-sectional view of the second bracket assembly, and the second bracket assembly can be approximately circular in cross-section, the center of the cross-section is approximately the center of the second filter screen 32, and the direction of the straight line passing through the center is the radial direction of the second bracket assembly. It should be noted that the second filter screen 32 has a certain machining size error, and therefore the distance between the mounting member 3311 and the second filter screen 32 is not necessarily a fixed value. In the embodiment of the present application, the thickness of the flexible member 2252 in the radial direction is set to be greater than the minimum distance between the mounting member 3311 and the second filter screen 32, so that the flexible member can contact as many positions of the second filter screen as possible, thereby improving the cleaning degree of the self-cleaning of the second filter screen.

[0086] In some embodiments, as shown in Figure 9 The second bracket assembly 33 includes a plurality of scrapers 331, which are arranged at intervals around the circumference of the inner side of the second filter screen 32, and the inclination directions of the plurality of scrapers 331 are the same. The number of scrapers 331 can be two, three, four, etc., and the present application does not limit the number of scrapers 331 arranged, wherein, Figure 19 In the embodiment shown, two scrapers 331 are arranged around the circumference of the inner side of the second filter screen 32, wherein both of the two scrapers 331 are arranged at a set angle with respect to the vertical direction, and the inclination directions of the two scrapers are the same. It should be noted that the inclination directions being the same means that the two inclined scrapers 331 have the same disturbance effect on the solid or liquid in the accommodation cavity during the rotation of the second bracket assembly 33. For example, during the rotation of the second bracket assembly, both of the two scrapers 331 accelerate the sedimentation of the solid in the accommodation cavity.

[0087] In some embodiments, as shown in Figure 10 The second bracket assembly 33 further includes a transmission shaft 332 and a connecting member 333. The transmission shaft 332 extends in the vertical direction, one end of the transmission shaft 332 is connected to the bracket driving device 34, and the bracket driving device 34 can drive the transmission shaft 332 to rotate. The connecting member 333 connects the transmission shaft 332 and the mounting member 3311. The transmission shaft 332 drives the connecting member 333 to rotate, and the connecting member 333 drives the scraper 331 to rotate. In the embodiment of the present application, the second bracket assembly is arranged in the form of a transmission shaft and a connecting member, which is conducive to reducing the assembly difficulty of the bracket driving device and the scraper. In the case where a plurality of scrapers are arranged, the plurality of scrapers are connected to the same transmission shaft through the connecting member 333, thereby reducing the assembly structure of the entire second bracket assembly.

[0088] In some embodiments, as shown in Figure 2As shown, the second filter assembly 3 also includes a filter frame 35. The filter frame 35 is disposed on the outside of the second filter screen 32 and connects the second filter screen 32 and the first housing 37. The filter frame 35 fixes the second filter screen 32. In some embodiments, a fixing block may be provided at the bottom of the filter frame 35, and the second filter screen is fixed to the first housing 37 by means of snap-fitting or threaded connection with the fixing block.

[0089] In some embodiments, such as Figure 10 and Figure 11 As shown, the separator 100 also includes a flow guide 5. The flow guide 5 has a horizontally extending flow channel 51 inside, which connects the second outlet 31 and the outlet channel 41. In this embodiment of the invention, by providing a flow guide connecting the second filter assembly and the outlet, the flow guide can guide the filtered liquid in the second filter assembly to the outlet, which not only improves the ease of assembly between the second filter assembly and the filter device, but also enables the guidance and merging of the liquid.

[0090] In some embodiments, such as Figures 5-11 As shown, the second filter assembly 3 also includes a drain channel 36. One end of the drain channel 36 is connected to the receiving cavity 321, and the other end of the drain channel 36 is provided with a drain port 361, which connects to the outside of the separator. Specifically, a drain valve can be installed in the drain channel 36, and the opening state of the drain port 361 can be controlled by controlling the drain valve. When the separator 100 is installed in a dishwasher, the drain port 361 can connect to the outside of the dishwasher to facilitate the discharge of solid residue in the receiving cavity to the outside of the dishwasher.

[0091] The following combination Figure 5 Taking the application of separator 100 in a dishwasher as an example, the entire cyclone separation process will be explained. Dishwashers clean dishes by rinsing them with liquid to remove residue. However, the liquid left after rinsing contains solid residue, which hinders its recycling. The separator separates the rinsed fluid, filtering out solid residue. The separated liquid can then be reused to rinse dishes again, reducing secondary contamination from residue. Figure 5 As shown, the arrows indicate the direction of fluid movement. The upper end of the water cup 1 receives liquid mixed with solid residue. The solid-liquid mixture enters the inlet chamber 11, which can store the fluid. The fluid in the inlet chamber 11 enters the first vortex channel 2121 from the vortex inlet 2122. Because the first vortex channel rotates around the first direction ( Figure 8 As shown in the direction perpendicular to the paper, the fluid, a mixture of liquid and solid, rotates within the structural constraints of the vortex assembly 210. The solids in the fluid are propelled towards the wall of the vortex casing 212 due to the greater inertial centrifugal force than the liquid.Figure 8 As shown, the first filter screen 22 arranged in the cyclone passage 211 can guide the liquid in the cyclone passage 211 into the first water passage 221, and block the solid residues in the cyclone passage 211 between the first filter screen 22 and the cyclone shell 213. Most of the liquid can pass through the first filter screen 22 into the first water passage 221, and flow out through the first water outlet 21 for recycling of the dishwasher. A small part of the liquid remains in the first filter screen 22 and continues to move along the first water passage 221 in the first direction (from right to left in FIG. 4). Figure 8 As shown, the liquid can drive the solid residues to move in the direction of the cyclone outlet 2132, and discharge the residues and a small amount of liquid through the cyclone outlet 2132 into the second filter assembly. Figure 6 As shown, the liquid can drive the solid residues to move in the direction of the cyclone outlet 2132, and discharge the residues and a small amount of liquid through the cyclone outlet 2132 into the second filter assembly. Figure 6 As shown, the liquid can drive the solid residues to move in the direction of the cyclone outlet 2132, and discharge the residues and a small amount of liquid through the cyclone outlet 2132 into the second filter assembly.

[0092] The embodiment of the present application also provides a cleaning device, as shown in the figure, the cleaning device can be a dishwasher, a washing machine and the like, and the embodiment of the present application takes the dishwasher as an example for description, and the cleaning device comprises the separator 100 and the cleaning shell 200 according to any one of the above embodiments. The cleaning shell 200 is internally provided with the separated cleaning cavity 201 and the separation cavity 202, and the separation indicates that the cleaning cavity 201 and the separation cavity 202 are separated from each other and not communicated with each other, and only a specific pipeline can communicate the cleaning cavity 201 and the separation cavity 202. The cleaning cavity 201 in the embodiment of the present application is used for accommodating objects to be cleaned, for example, the cleaning cavity 201 can be used for accommodating dishes 300 such as plates, bowls and chopsticks, the separator 100 is arranged in the separation cavity 202, and the cleaning shell 200 is also provided with the inlet pipeline 203 and the outlet pipeline 204, the inlet pipeline 203 communicates the cleaning cavity 201 with the cyclone inlet of the separator 100, and the outlet pipeline 204 communicates the third water outlet of the separator 100 with the cleaning cavity 201. Figure 20 In combination with

[0093] In combination with Figure 20As shown, the inlet pipe 203 connects to the water cup, and the outlet pipe 204 connects to the water outlet channel. The following describes the dishwasher's operation:

[0094] like Figure 5 As shown, the tableware 300 to be washed is placed in the cleaning chamber 201. Clean liquid impacts the surface of the tableware 300, rinsing away residue and forming a solid-liquid mixture containing residue. To improve the cleanliness of the tableware 300, it needs to be rinsed multiple times, requiring separation of the solid-liquid mixture to form a residue-free liquid. The liquid is then processed and circulated to rinse the tableware 300 again. Figure 10 As shown, the solid-liquid mixture after rinsing the tableware 300 flows to the base 206, and then is guided to the water inlet chamber 11 through the inlet pipe 203. The solid-liquid mixture in the water inlet chamber 11 is then introduced into the vortex channel through the vortex inlet 2122. After being filtered by the first filter screen, most of the liquid enters the water outlet channel 41 through the first outlet 21 (see reference). Figure 9 The remaining liquid flushes the solids filtered out by the first filter into the second filter assembly; for example... Figure 10 As shown, the second filter assembly can collect solid residue and guide the remaining liquid into the outlet chamber 311. The remaining liquid then flows through the outlet chamber 311 into the outlet channel 41 (see reference). Figure 16 Inside the water outlet 311, the liquid discharged from the water outlet merges with the liquid discharged from the first water outlet, and finally circulates from the third water outlet 42 into the cleaning chamber 201 for the cyclic rinsing of the tableware 300.

[0095] In some embodiments, a washing pump 205 is provided in the outlet pipe 204. By providing the washing pump 205, a negative pressure is formed in the outlet pipe 204, and a pressure difference is formed between the outlet pipe 204 and the drainage channel, so that the liquid in the drainage channel can flow into the outlet pipe quickly, thereby improving the efficiency of circulating liquid diversion.

[0096] In some embodiments, such as Figure 20 As shown, the outlet pipe 204 includes a lower spray arm 207, a middle spray arm 208, and an upper spray arm 209. The lower spray arm 207, middle spray arm 208, and upper spray arm 209 are interconnected via a pipe 2072, and are spaced apart in the vertical direction of the cleaning chamber 201. Of course, in other embodiments, the lower spray arm 207, middle spray arm 208, and upper spray arm 209 can be spaced apart in other directions of the cleaning chamber 201. The tableware 300 within the cleaning chamber 201 can be arranged in multiple rows. By setting the lower spray arm 207, middle spray arm 208, and upper spray arm 209, each spray arm is positioned opposite a row of tableware, facilitating precise rinsing of the tableware and improving the cleanliness of the dishes. ​As shown, the lower spray arm 207, the middle spray arm 208 and the upper spray arm 209 are each provided with a plurality of spray nozzles 2071 in the horizontal direction, the spray nozzles 2071 being used to guide the liquid in the lower spray arm 207, the middle spray arm 208 and the upper spray arm 209 to the surface of the object to be cleaned in the cleaning cavity 201, by providing the plurality of spray nozzles 2071, the area of the liquid flushing in the cleaning cavity is facilitated, thereby improving the cleaning degree of the tableware in the cleaning cavity.

[0097] The above merely provides the preferred embodiments of the present application, but not for limiting the protection scope of the present application.
