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.

The separator is described below by taking the application of the separator in a dishwasher as an example. The separator in the embodiment of the present application can separate a mixed fluid containing solids and liquids into separate liquids or separate solids.

The embodiment of the present application provides a separator 100, as shown in Figures 1 and 2, the separator 100 includes a water cup 1, a first filter assembly 2, a second filter assembly 3 and a water outlet 4. Figure 1 shows a stereoscopic view of the separator 100 of the embodiment of the present application, and Figure 2 shows an exploded view of the separator 100 of the embodiment of the present application. A water inlet chamber 11 is provided inside the water cup 1, and one end of the water inlet chamber 11 is open in the vertical direction. It should be noted that the vertical direction described in the embodiment of the present application represents the up and down direction in the absolute coordinate system. The water inlet chamber 11 is connected to the outside of the separator 100. When the separator 100 is used in a dishwasher, the water inlet chamber 11 can be used to receive the fluid to be separated in the dishwasher, and the fluid can be introduced into the water inlet chamber 11 through the upper end of the water cup 1.

As shown in FIG1 , the first filter assembly 2 is connected to the water cup 1. The first filter assembly 2 is provided with a first water outlet 21. After the fluid is introduced from the upper end of the water cup 1 into the water inlet chamber 11, the fluid in the water inlet chamber 11 can flow into the first filter assembly 2. The first filter assembly 2 is used to guide the fluid in the water inlet chamber 11 to spirally move, 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 means that the fluid entering the first filter assembly 2 from the water inlet chamber 11 can spirally rotate around the first direction. The fluid in spiral motion will be subjected to centrifugal force. Since the density of the solid in the fluid is greater than the density of the liquid, the centrifugal force on the solid in the fluid is greater than the centrifugal force on the liquid, so that most of the solid and liquid in the fluid can be separated in the first filter assembly 2. Among them, the first water outlet 21 in the first filter assembly 2 is used to export the liquid separated from the first filter assembly 2.

As shown in FIG. 1 and FIG. 2 , the second filter assembly 3 is disposed outside the water cup 1 . It should be noted that the outside of the water cup 1 represents the second filter assembly 3 which does not overlap with the water cup 1 in position.

In the embodiment of the present application, the second filter component 3 is connected to the first filter component 2, and the first filter component 2 introduces the unfiltered fluid into the second filter component 3, that is, the first filter component 2 filters the liquid from the fluid and guides it out from the first water outlet 21, and the remaining solids and The liquid is introduced into the second filter component 3 for filtration. The second filter component 3 is provided with a second water outlet 31 . The second filter component 3 filters the fluid introduced from the first filter component 2 , retains all solids in the fluid in the second filter component 3 , and discharges the liquid in the fluid from the second water outlet 31 .

As shown in FIG2 , in the embodiment of the present application, a water outlet 4 is provided, and the water outlet 4 is used to merge the liquid of the first water outlet 21 and the second water outlet 31, and uniformly export them from the third water outlet 42 of the water outlet 4, so as to be recycled by the cleaning equipment. Among them, FIG10 is a cross-sectional view of the E-E portion in FIG7 , which illustrates the connection relationship between the water outlet 4 and the first water outlet 21 and the second water outlet 31. In combination with FIG10 , a water outlet channel 41 is provided inside the water outlet 4, and the water outlet channel 41 connects the first water outlet 21 and the second water outlet 31. The water outlet 4 is also provided with a third water outlet 42 connected to the water outlet channel 41. The water outlet 4 can be understood as a three-way pipe, that is, the water outlet 4 is connected to the first water outlet 21 and the second water outlet 31 by setting the water outlet channel 41, and the liquid filtered in the first filter assembly 2 can be introduced from the first water outlet 21 to the water outlet channel 41, and the liquid filtered in the second filter assembly 3 can be introduced from the second water outlet 31 to the water outlet channel 41. The liquid introduced by the first water outlet 21 and the second water outlet 31 merges in the water outlet channel 41 and then is discharged from the third water outlet 42 .

The embodiment of the present application provides a separator and a cleaning device, which includes a water cup, a first filter component, a second filter component and a water outlet. The water cup is provided with a water inlet chamber, which is connected to the outside of the separator. The first filter component is connected to the water cup, and the first filter component is provided with a first water outlet. The first filter component is provided with a vortex channel and a first filter net rotating around a first direction. The first filter net guides the liquid passing through the vortex channel into the first filter net, and the first water outlet is connected to the inside of the first filter net; the second filter component is provided outside the water cup, the second filter component is connected to the first filter component, and the second filter net is provided with a second filter net inside. The second filter component is provided with a second water outlet connected to the outside of the second filter net, and the second filter net guides the liquid introduced from the first filter component to the second water outlet; the water outlet guides the liquid introduced by the first water outlet and the second water outlet from the third water outlet. The embodiment of the present application is provided with a first filter component and a second filter component, wherein a swirl channel and a first filter screen rotating about a first direction are provided in the first filter component, and a mixed fluid containing solids and liquids enters the swirl channel. Under the action of inertial centrifugal force, solids with a density much greater than that of liquids can move radially in a direction away from the first filter screen, and solids with a density slightly greater than that of liquids can move in a direction away from the first filter screen even if they cannot be separated from the liquid by the action of inertial centrifugal force. However, under the obstruction of the first filter screen, only the liquid can enter the first filter screen, and part of the liquid remaining outside the first filter screen can drive the solids to continue to flow to the second filter component, and the first filter screen can be used to filter the solids. The second filter screen can block solids inside, and the liquid flows from the inside of the second filter screen to the second water outlet outside the second filter screen. The second filter assembly is set outside the water cup, so that the second filter assembly and the water cup are set independently. The design size and structure of the water cup are not limited by the second filter assembly, which simplifies the design structure of the water cup, avoids the water cup from being nested with other components, and reduces the difficulty of manufacturing and assembling the separator. The design size of the water cup is more flexible, which is conducive to flexible control of the water intake of the water cup. When the water cup size is designed to be smaller, it is conducive to reducing the speed of the fluid introduced into the separator, thereby achieving the effect of saving water. The liquid filtered by the first filter assembly and the second filter assembly are combined and then discharged through the water outlet, which is conducive to increasing the flow rate of the exported fluid and simplifying the separation. The structure of the separator to export liquid.

In some embodiments, as shown in FIG3, the first filter assembly 2 includes a cyclone assembly 210 and a first filter screen 22. As shown in FIG4 and FIG5, the cyclone assembly 210 is provided with a cyclone channel 211 extending in the horizontal direction, the first filter screen 22 is at least partially arranged in the cyclone assembly 210, and the cyclone assembly 210 is provided with a cyclone channel 211 rotating around a first direction (vertical to the paper direction shown in FIG5), and the rotating arrangement indicates that the fluid can form a rotating flow fluid when passing through the cyclone channel 211, rather than only moving in a straight line. The cyclone channel 211 has a cyclone inlet 2122 and a cyclone outlet 2132 (as shown in FIG8) arranged at intervals in the first direction (vertical to the paper direction shown in FIG5), and the arrow direction in FIG5 indicates the movement direction of the fluid, the water inlet chamber 11 is connected to the cyclone inlet 2122, and the cyclone inlet 2122 is used to introduce the fluid to be separated into the cyclone channel 211, and as shown in FIG8, the cyclone outlet 2132 is used to export the solid or solid-liquid mixture separated in the cyclone channel 211. When the separator 100 is applied to a dishwasher, the solid may be food residues, etc. It should be noted that the first direction described in the embodiment of the present application is in the horizontal direction, and the horizontal direction represents the direction of the horizontal plane in the absolute coordinate system. The left and right directions shown in FIG8 can be used to represent the first direction.

In the embodiment of the present application, the area of the first filter 22 is larger than the area of the second filter 32. It should be noted that the first filter 22 can be roughly formed into a cylindrical structure, and the corresponding area of the first filter 22 represents the side area of the cylinder formed. The second filter 32 can also be roughly formed into a cylindrical structure, and the corresponding area of the second filter 32 represents the side area of the cylinder formed by the second filter 32. The area can be used to represent the amount of water passing through the first filter or the second filter. The larger the area, the greater the amount of water passing. In the embodiment of the present application, the area of the first filter 22 is larger than the area of the second filter 32. The number of first through holes that can be set on the first filter 22 is greater than the number of second through holes that can be set on the second filter 32. Therefore, the amount of water passing through the first filter is greater than the amount of water passing through the second filter. Furthermore, the first filter screen 22 is closer to the water inlet chamber 11 than the second filter screen 32, so the resistance of the liquid discharged from the first filter screen 22 is smaller than the resistance of the second filter screen 32. Therefore, most of the liquid passes through the first filter screen 22 and is discharged to the first water outlet 21, and the remaining small amount of liquid drives the solids blocked on the outside of the first filter screen 22 to be flushed to the second filter assembly, and the remaining small amount of liquid passes through the second filter screen and flows to the second water outlet 31.

As shown in FIG5 , the swirl channel 211 is connected to the bottom of the water inlet chamber 11. It should be noted that the bottom represents the bottom of the water inlet chamber 11 in the absolute coordinate system, that is, the swirl inlet 2122 is connected to the lower end of the water inlet chamber 11, which can be understood as the distance between the swirl inlet 2122 and the bottom of the water inlet chamber 11 is less than or equal to a set value, and the set value can be zero. In the embodiment of the present application, by connecting the swirl channel to the bottom of the water inlet chamber, when the amount of water in the water inlet chamber is small, the swirl inlet can also introduce the fluid at the bottom of the water inlet chamber into the swirl channel, thereby reducing the water inlet height of the swirl channel, making it difficult for the air in the water inlet chamber to enter the swirl channel from the swirl inlet, and also making it difficult for the swirl channel to have air suction.

As shown in FIGS. 7 and 8 , the first filter screen 22 is disposed in the swirl channel 211, and a first water passage 221 extending in the horizontal direction is disposed inside the first filter screen 22, wherein the first filter screen 22 is at least disposed in the swirl channel 211, and at least disposed in the swirl channel 211 means that the first filter screen 22 can be completely disposed in the swirl channel 211, or can be partially disposed in the swirl channel 211. The first filter 22 has a first water passage 221 extending in a 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 connected to the swirl channel 211. The first filter 22 is used to guide the liquid passing through the swirl channel 211 into the first water passage 221, and block the solid passing through the swirl channel 211, so that the solid passing through the swirl channel 211 is retained between the first filter 22 and the swirl assembly 210. As shown in FIG8, the first water outlet 21 is provided at one end of the first water passage 221 in the horizontal direction. The first water outlet 21 is used to discharge the liquid in the first water passage 221. When the separator 100 is used in a dishwasher, the liquid discharged from the first water outlet 21 can be recycled by the dishwasher.

In the embodiment of the present application, the vortex channel is rotated around a first direction, and the first filter is arranged in the vortex channel. A mixed fluid containing solids and liquids enters the vortex channel through the vortex inlet. Under the action of inertial centrifugal force, solids with a density much greater than that of liquids can move radially in a direction away from the first filter. Even if the solids with a density slightly greater than that of liquids cannot be separated from the liquid by the action of inertial centrifugal force, only the liquid can enter the first water passage due to the obstruction of the first filter. The part of the liquid remaining between the first filter and the vortex component can drive the solids to continue to flow to the vortex outlet, and the solids and a small amount of liquid are discharged to the second filter component at one time through the vortex outlet, which is beneficial to improving the efficiency of liquid separation. The solids will not stay in the vortex channel to block the first filter, which is beneficial to improving the fluidity of the liquid in the first water passage and facilitating the recycling of the liquid.

In some embodiments, as shown in FIG. 3, FIG. 5 and FIG. 8, the swirl assembly 210 includes a swirl volute 212 and a swirl housing 213. As shown in FIG. 5, a first swirl channel 2121 rotating around a first direction (vertical to the paper direction shown in FIG. 5) is formed inside the swirl volute 212, and the first swirl channel 2121 is provided with a swirl inlet 2122 in the circumferential direction. It should be noted that the circumferential direction is the direction surrounding the first direction. A second swirl channel 2131 extending along the first direction (left-right direction shown in FIG. 8) is formed inside the swirl housing 213, and the extension direction of the second swirl channel 2131 represents the maximum dimension direction of the second swirl channel 2131. The second swirl channel 2131 is connected to the first swirl channel 2121 at one end in the first direction (the right end shown in FIG8 ), and the other end of the second swirl channel 2131 (the left end shown in FIG8 ) is provided with a swirl outlet 2132. It should be noted that the other end of the second swirl channel 2131 represents the position of the second swirl channel 2131 away from the first swirl channel 2121, and the swirl outlet 2132 is not located at the leftmost end of the second swirl channel 2131 in the first direction. The swirl outlet 2132 can also be set at a position where the distance from the leftmost end is less than a certain range. The first swirl channel 2121 and the second swirl channel 2131 in the embodiment of the present application together form the swirl channel 211. By arranging a first swirl channel rotating about a first direction in the swirl volute, the fluid passing through the first swirl channel can utilize inertial centrifugal force to separate solids and liquids, so that most of the liquid can enter the first water passage. By arranging a second swirl channel extending along the first direction in the swirl housing, since the first filter screen and the second swirl channel both extend along the first direction, which is different from the direction of liquid flow in the first swirl channel, after the liquid enters the second swirl channel, the direction of the liquid will change, which plays a rectifying role. Part of the liquid can enter the first water passage, and the liquid in the first water passage can pass through the second swirl channel. The liquid is led out through an outlet for recycling; the other part of the liquid can continue to move in the second cyclone channel along the first direction, thereby driving the solids in the second cyclone channel to move to the cyclone outlet to achieve the screening of the solids.

In some embodiments, as shown in FIG8 , the first filter assembly further includes an inner cylinder 223. A first water passage 221 is formed inside the first filter screen 22, and the first water passage 221 extends along a first direction (left-right direction shown in FIG8 ). The first filter screen 22 in the embodiment of the present application extends from the first vortex channel 2121 to the second vortex channel 2131 along the first direction. In other words, 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 221 is connected to the vortex channel 211. Specifically, in some embodiments, a plurality of first through holes are provided on the first filter screen 22, and the first through holes connect the first water passage 221 and the vortex channel 211. Due to the limitation of the first through holes, the liquid in the vortex channel 211 can flow into the first water passage 221 through the first through holes, but the solid in the vortex channel 211 cannot pass through the first through holes and can only be blocked by the first through holes to between the first filter screen 22 and the vortex assembly.

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 to a cylindrical hole, then the diameter of the first through hole represents the diameter of a circle. Of course, the cross section of the first through hole can also be set to an irregular shape, for example, the cross section of the first through hole can be set to an ellipse, a triangle, a square, etc. When the cross section of the first through hole is set to an irregular shape, the diameter of the first through hole can be represented by the diameter of a standard circle of equal area. In the embodiment of the present application, by setting the diameter of the first through hole within a certain range, the first through hole can filter out 99% of the solids in the fluid, which can be regarded as the first filter almost completely separating the solids and liquids in the fluid.

As shown in Figure 8, in the embodiment of the present application, the first filter screen 22 is extended from the first vortex channel 2121 to the second vortex channel 2131 along the first direction, and the fluid mixed with solids and liquids enters the first vortex channel 2121 from the vortex inlet 2122, and part of the liquid can pass through the first filter screen 22 located in the first vortex channel 2121 and enter the first water passage 221, and the remaining fluid can continue to flow into the second vortex channel 2131. After the fluid enters the second vortex channel 2131, part of the liquid passes through the first filter screen 22 located in the second vortex channel 2131 and enters the first water passage 221, and the remaining small amount of liquid can drive the solids to continue to move along the first direction, so as to drive the solids to be discharged from the vortex outlet 2132, thereby reducing the risk of solids clogging the first filter screen 22 and improving the fluidity of the liquid in the first water passage. The first filter extends into the first cyclone channel, which can improve the efficiency of fluid filtration. The first filter extends into the second cyclone channel. The extension direction of the first filter in the second cyclone channel is inconsistent with the original flow direction of the fluid in the first cyclone channel. The first filter in the second cyclone channel can rectify the fluid, greatly weakening the cyclone intensity of the liquid entering the first water passage, which can greatly reduce the resistance of the entire separator and help improve the stability of the separator structure. In addition, the length of the first filter is relatively long, which is conducive to improving the efficiency of filtration.

As shown in FIG8 , the inner cylinder 223 is hollow inside and is disposed in the first water passage 221. The inner cylinder 223 is hollow inside and can be understood as the inner cylinder 223 being open at both ends in the first direction. The inner cylinder 223 is connected to the first water outlet 21 at one end in the first direction, and the inner cylinder 223 is connected to the first water passage 221 at the other end in the first direction. The inner cylinder 223 is arranged through in the first direction, and the inner cylinder 223 is fixedly connected to the inner wall surface of the swirl volute 212 at one end in the first direction (the right end shown in FIG8 ) and is connected to the first water outlet 21. As shown in FIG8 , the inner cylinder 223 is connected to the first water passage 221 at the other end in the first direction (the left end shown in FIG7 ). Among them, the first water outlet 21 can be arranged through at one end of the swirl volute 212 in the first direction, and the inner cylinder 223 can cover the entire first water outlet 21, so that the liquid in the first water passage 221 can only flow to the first water outlet 21 through the interior of the inner cylinder 223. The embodiment of the present application is conducive to rectifying the liquid before it flows out to the first water outlet by arranging the inner cylinder in the first water passage, thereby improving the consistency of the liquid movement direction.

In some embodiments, as shown in FIG5 , the width of the first vortex channel 2121 narrows along the direction of fluid flow (the direction indicated by the arrow in FIG5 indicates the direction of fluid flow). It should be noted that the flow direction of the fluid in the first vortex channel 2121 is to enter the first vortex channel 2121 from the vortex inlet 2122, and then flow in a spiral along the first vortex channel 2121. The embodiment of the present application gradually narrows the width of the first vortex channel, which is beneficial to changing the direction of movement of the fluid and making the fluid spirally move so that the solids in the fluid generate inertial centrifugal force during the movement; according to the principles of fluid dynamics, the width of the first vortex channel becomes narrower, and the speed of the fluid becomes faster, which is beneficial to improving the efficiency of separator filtration.

As shown in FIG8, the second vortex channel 2131 includes a first sub-chamber 2133 and a second sub-chamber 2134 separated in the vertical direction. It should be noted that the separation means that the first sub-chamber 2133 and the second sub-chamber 2134 are independent of each other in the vertical direction, but not completely closed. The first sub-chamber 2133 and the second sub-chamber 2134 can be connected at one end in the first direction. For example, in the embodiment shown in FIG8, the first sub-chamber 2133 and the second sub-chamber 2134 are connected at one end (the left end shown in FIG8) away from the first vortex channel 2121 in the first direction, and the first filter The net 22 is partially located in the first sub-cavity 2133, and the first sub-cavity 2133 is connected to the first vortex channel 2121 and the second sub-cavity 2134 at both ends in the first direction. As shown in FIG8 , the fluid entering the first vortex channel 2121 will continue to flow forward (leftward as shown in FIG8 ) along the first sub-cavity 2133, and part of the liquid enters the first water passage 221, and the remaining liquid drives the solid to continue to move into the second sub-cavity 2134. The second sub-cavity 2134 is provided with a vortex outlet 2132, and the solid and a small amount of liquid can be discharged through the vortex outlet 2132. The embodiment of the present application divides the second vortex channel into the first sub-cavity and the second sub-cavity in the vertical direction, so that the fluid mixed with solids and liquids enters the second sub-cavity from the first sub-cavity and then is discharged through the vortex outlet, which is conducive to reducing the risk of solids flowing back to the first vortex channel again, and is also conducive to setting the height of the vortex outlet at a lower level to improve the efficiency of fluid discharge.

In some embodiments, in combination with FIG. 3 and FIG. 8 , the first filter screen 22 further includes a filter screen drive device 224 and a first bracket assembly 225. The filter screen drive device 224 is connected to the first filter screen 22, and the filter screen drive device 224 is used to drive the first filter screen 22 to rotate around a first direction (left-right direction as shown in FIG. 8 ). It should be noted that the embodiment of the present application does not limit the frequency and speed of the rotation of the filter screen drive device 224, as long as the filter screen drive device 224 can drive the first filter screen 22 to rotate. In the process of the liquid in the swirl channel entering the first water passage, the solid in the swirl channel is moved by the first The filter screen is blocked outside the first water flow channel, and 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. The embodiment of the present application drives the first filter screen to rotate through the filter screen driving device. The solids on the first filter screen will separate from the surface of the first filter screen under the action of inertia, thereby reducing the risk of solids adhering to the first filter screen, and is beneficial to improving the water flow efficiency of the first filter screen. It can also realize self-cleaning of the first filter screen, eliminating the need for cleaning, and improving the user's convenience in operation.

As shown in FIG. 3 and FIG. 8, the first bracket assembly 225 is fixed between the swirl assembly (refer to the swirl volute 212 and the swirl housing 213 shown in FIG. 8) and the first filter screen 22. It should be noted that the embodiment of the present application does not limit the fixing method of the above-mentioned first bracket assembly 225. The first bracket assembly 225 can be directly fixed to the swirl assembly, and the first bracket assembly 225 can also be indirectly fixed to the swirl assembly through other components. However, no matter what kind of fixing form is adopted, as long as the first bracket assembly 225 is stationary relative to the swirl channel. As shown in FIG. 8, the first bracket assembly 225 is at least partially in contact with the first filter screen 22. Among them, the part of the first bracket assembly 225 that contacts the first filter screen 22 extends in the spiral direction, and the part of the first bracket assembly 225 that contacts the first filter screen 22 is a spirally wound structure, which is not a linear contact, nor a surface contact.

During the process of the first filter assembly filtering the fluid, a small amount of pollutants may still adhere to the first filter screen. In the embodiment of the present application, a first bracket assembly is set. During the rotation of the first filter screen 22, since the first bracket assembly 225 is stationary relative to the swirl assembly, the first filter screen 22 rotates relative to the first bracket assembly 225. The contact between the first bracket assembly 225 and the first filter screen 22 enables the horizontal bracket assembly to scrape off the pollutants on the first filter screen, and the first bracket assembly 225 is in at least partial spiral contact with the first filter screen 22. The fluid in the first filter assembly also spirally moves around the first direction. The spirally contacted portion is roughly the same as the movement direction of the fluid in the first filter assembly, which is beneficial to reducing the interference of the first bracket assembly on the swirl field in the swirl channel and reducing the risk of channel blockage in the swirl channel.

In some embodiments, as shown in FIG8 , the first filter screen 22 further includes a flow guide 226. The flow guide 226 is disposed in the first water passage 221, and the flow guide 226 is connected to the filter screen drive device 224. It should be noted that the flow guide 226 can be fixedly connected to the filter screen drive device 224, and the embodiment of the present application does not limit the specific connection form of the flow guide 226 and the filter screen drive device 224. For example, the flow guide 226 can be permanently connected to the filter screen drive device 224 by welding or integral molding. For another example, the flow guide 226 can also be detachably connected to the filter screen drive device 224 by means of snap connection, etc., as long as the rotation of the filter screen drive device 224 can drive the flow guide 226 to rotate.

Among them, as shown in FIG8 , the cross-sectional area of the guide member 226 gradually increases from the end close to the swirl volute 212 to the end connected to the filter drive device 224. The cross section of the guide member 226 is perpendicular to the first direction, and the cross-sectional area can be understood as the area of the cross section of the guide member 226. In some embodiments, the guide member 226 can be set to a cone, then the cross section of the guide member 226 is circular, so the change in the diameter of the guide member 226 in the cross section shown in FIG8 can be used to represent the change trend of the cross-sectional area. Combined with FIG9 , 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 swirl channel 2131 is in the guide member 226. Under agitation, the liquid will flow along the surface of the guide member 226 toward the direction away from the center of the guide member 226, that is, the liquid will flow 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 will flow along the surface of the guide member 226 toward the first sub-chamber 2133, and the liquid flowing toward the first sub-chamber 2133 will drive the solids in the first sub-chamber 2133 to flow toward the second sub-chamber 2134, which is beneficial for the liquid to guide the solids in the first sub-chamber to the second sub-chamber, thereby improving the separation efficiency of the separator.

In some embodiments, as shown in FIGS. 12-15 , the first bracket assembly 225 includes a fixing frame 2251. The fixing frame 2251 is connected to a side of the swirl assembly 210 close to the swirl channel 211 (as shown in combination with FIG. 8 ). As shown in FIG. 12 , the flexible member 2252 is fixed to the fixing frame 2251, the flexible member 2252 is spirally arranged around the first direction, and the flexible member 2252 is in contact with the first filter 22; it should be noted that the flexible member 2252 represents a component composed of a material with a lower hardness, and the hardness of the flexible member 2252 is less than the hardness of the fixing frame 2251. The flexible member in the embodiment of the present application can be made of rubber or a brush, etc. By making the flexible member of a material with a lower hardness, it is beneficial to improve the fit between the flexible member 2252 and the first filter 22, and it is beneficial to reduce the resistance of the first filter to the flexible member while improving the cleaning efficiency of the first filter 22, thereby reducing the energy consumption of driving the first filter to rotate. The flexible member with lower hardness is provided to facilitate the adaptation of the first filter screen with low processing precision or roundness, so that the flexible member contacts the first filter screen as much as possible, thereby improving the cleanliness of the first filter screen. The fixing frame 2251 in the embodiment of the present application plays a role of supporting and fixing the flexible member 2252.

In the embodiment of the present application, the spiral direction of the swirl channel 211 can refer to the direction shown by the dotted arrow in FIG. 3 . The spiral direction of the swirl channel 211 is defined as the counterclockwise direction in the embodiment of the present application. Then, correspondingly, the spiral direction of the flexible member 2252 is consistent with the spiral direction of the swirl channel 211, that is, the spiral direction of the flexible member 2252 is also spiral in the counterclockwise direction. In the embodiment of the present application, the spiral direction of the swirl channel 211 is arranged to be consistent with the spiral direction of the flexible member 2252, so that the movement direction of the fluid entering the swirl channel 211 from the swirl inlet is consistent with the spiral direction of the flexible member, which is conducive to reducing the resistance of the flexible member to the movement of the fluid, thereby improving the effect of the spiral movement of the fluid in the swirl channel. 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 significant impact on the fluid in the swirl channel.

In some embodiments, as shown in FIG. 13 and FIG. 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 fixing frame 2251. FIG. 14 shows a cross-sectional schematic diagram of the first bracket assembly, wherein the first bracket assembly may be a roughly circular cross-section, the center of the cross-section is roughly the center of the first filter screen 22, and the direction of the straight line passing through the center of the circle is the radial direction of the first bracket assembly. It should be noted that the first filter screen 22 has a certain processing dimensional error, and therefore, the distance between the fixing frame 2251 and the first filter screen 22 is not necessarily a constant value. In the embodiment of the present application, by setting the thickness of the flexible member 2252 in the radial direction to be greater than the minimum distance between the fixing frame and the first filter screen, the flexible member is able to contact each part of the first filter screen as much as possible. position, thereby improving the cleanliness of the first filter screen self-cleaning.

As shown in FIG. 12 , the fixing frame 2251 includes a first bracket 2253. The first bracket 2253 is fixed to the inner side of the swirl assembly 210, the first bracket 2253 is spirally arranged around the first direction, and the flexible member 2252 is connected to the first bracket 2253. The extension direction of the first bracket 2253 is consistent with the extension direction of the flexible member 2252, and the first bracket 2253 can fix the flexible member 2252. In the embodiment of the present application, by spirally arranging the first bracket around the first direction, the first bracket can not only stably fix the flexible member, but also help reduce the obstruction of the first bracket to the fluid in the swirl channel.

In some embodiments, as shown in FIG12 , the fixing frame 2251 further includes a plurality of second brackets 2254. The plurality of second brackets 2254 are arranged in a ring shape, the plurality of second brackets 2254 are spaced apart in the first direction, and the plurality of second brackets 2254 are all connected to the first bracket 2253, and at least some of the second brackets 2254 are all sleeved on the outside of the first filter 22. The number of the second brackets 2254 can be one, two, three, four, etc. In the embodiment shown in FIG12 , the second brackets 2254 are arranged in two, the two second brackets 2254 are respectively connected to the two ends of the first bracket 2253 in the first direction, and the two second brackets 2254 are sleeved on the outside of the first filter 22, and the second brackets 2254 can play a positioning role on the first filter to improve the stability of the movement of the first filter.

In some embodiments, as shown in FIG12 , the fixing frame 2251 further includes a third bracket 2255. The third bracket 2255 extends along the first direction, and the third bracket 2255 connects the plurality of second brackets 2254 and the first bracket 2253. In the embodiment of the present application, by providing a third bracket connecting the first bracket and the second bracket, and the third bracket extending along the first direction, it is beneficial to improve the structural strength of the first bracket and the second bracket, thereby improving the structural stability of the fixing frame.

In some embodiments, as shown in FIG. 2 and FIG. 9 , the second filter assembly 3 includes a first housing 37 and a second filter screen 32. As shown in FIG. 9 , a water outlet chamber 311 extending in a vertical direction is provided inside the first housing 37 . 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 chamber 311 , and a receiving chamber 321 communicating with the water outlet chamber 311 is provided in the second filter screen 32 . As shown in FIG. 8 , the receiving chamber 321 communicates with the swirl outlet 2132 and the water outlet chamber 311 . The second filter screen 32 is used to guide the liquid between the first filter screen 22 and the swirl assembly 210 to the water outlet chamber 311 , and to retain the solids between the first filter screen 22 and the swirl assembly 210 in the receiving chamber 321 . The receiving chamber 321 can collect solids in the fluid, which is convenient for the centralized export of solids. The liquid in the water outlet chamber 311 can be introduced into the dishwasher again for recycling of the dishwasher.

The second filter 32 extends in the vertical direction. It should be noted that the extension direction of the second filter 32 in normal use is parallel to the vertical direction. The second filter 32 can be set as a structure that penetrates in the vertical direction. At least one end of the second filter 32 in the vertical direction is open. As shown in FIG9 , the lower end of the second filter 32 is open. The lower end of the second filter 32 is connected to the swirl outlet 2132 (as shown in FIG8 ). The fluid derived from the swirl outlet 2132 can enter the accommodating chamber 321 from the lower end of the second filter 32. The upper end of the second filter 32 in the vertical direction abuts against the inner wall surface of the first shell 37. It should be noted that the abutment between the second filter 32 and the inner wall surface of the first shell 37 indicates that the second filter 32 may not have a fixed connection relationship with the first shell 37, and the second filter 32 and the first shell 37 may be in close contact, so that the second filter 32 can be connected to the first shell 37. The second filter screen 32 can 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 accommodating chamber 321 flowing from the gap to the water outlet chamber 311. In addition, the second filter screen extends in the vertical direction, which can share the collection function of the first filter screen for solid residues, which is conducive to reducing the structural size of the first filter screen in the horizontal direction and improving the overall structural compactness of the separator.

In some embodiments, as shown in FIG. 2 and FIG. 9 , the second filter assembly 3 further includes a second bracket assembly 33 and a bracket driving device 34. The second bracket assembly 33 is movably disposed in the accommodating cavity 321, and the second bracket assembly 33 includes a scraper 331, the scraper 331 contacts the inner side of the second filter screen 32, and the extension direction of the scraper 331 forms a set angle θ with the vertical direction. It should be noted that the extension direction of the scraper 331 represents the maximum dimension direction of the scraper 331, which can be understood as the length direction of the scraper. The length direction of the scraper 331 forms a set angle θ with the vertical direction, and the bracket driving device 34 is connected to the second bracket assembly 33, and the bracket driving device 34 is used to drive the scraper 331 to rotate relative to the second filter screen 32. The inclination direction of the scraper blade 331 is consistent with the direction in which the scraper blade 331 is driven to rotate by the bracket driving device 34. For example, as shown in Figure 9, the scraper blade 331 can be understood to be extended in the counterclockwise direction. The left end of the scraper blade 331 is closer to the top of the second filter screen 32 relative to the right end. The bracket driving device 34 drives the scraper blade 331 to rotate counterclockwise, so that during the rotation of the scraper blade 331, the scraper blade 331 can provide both a circumferential force on the solid and a downward force on the solid, which is beneficial to increase the sedimentation rate of the solid in the accommodating chamber, thereby helping to improve the efficiency of extracting solid impurities.

In some embodiments, as shown in FIG9 , one end of the scraper 331 (the upper end shown in FIG9 ) 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 (the lower end shown in FIG9 ). It should be noted that “close” means that the distance between the two ends of the scraper 331 and the two ends of the second filter 32 in the vertical direction is relatively close. In the embodiment of the present application, by placing the two ends of the scraper close to the two ends of the second filter, the scraper can rotate to contact various positions of the second filter as much as possible, thereby increasing the cleaning area of the second filter and minimizing the risk of residue clogging the second filter.

In some embodiments, as shown in FIG9 , the set 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, and the set angle θ can be 30 degrees, 40 degrees, 45 degrees, 50 degrees, 60 degrees, etc. The embodiment of the present application limits the set angle of the scraper to a certain range, which can not only increase the speed of solid sedimentation in the receiving chamber, but also reduce the interference effect on the flow of liquid in the receiving chamber, thereby improving the efficiency of liquid flowing from the receiving chamber to the water outlet chamber.

In some embodiments, as shown in FIG. 10 , 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 a set angle, the flexible member 2252 is arranged along an extension direction of the mounting member 3311, and the flexible member 2252 is fixed to a side of the mounting member 3311 close to the second filter screen 32. The flexible member 2252 represents a component composed of a material with a lower hardness. The flexible member in the embodiment of the present application may be made of rubber or a brush, etc. By making the flexible member of a material with a lower hardness, it is beneficial to improve the fit between the flexible member 2252 and the second filter screen 32, which can improve the cleaning efficiency of the second filter screen 32 and also help to reduce The second filter 32 acts as a resistance to the flexible member, thereby reducing the energy consumption of driving the second filter 32 to rotate. In addition, the provision of a flexible member with lower hardness is conducive to adapting the second filter 32 with low processing precision or roundness, so that the flexible member is in contact with the second filter 32 as much as possible, thereby improving the cleanliness of the second filter 32. The mounting member 3311 in the embodiment of the present application plays a role in supporting and fixing the flexible member 2252.

As shown in FIG. 17 and FIG. 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 32. FIG. 18 shows a cross-sectional schematic diagram of the second bracket assembly, wherein the second bracket assembly may be approximately a circular cross-section, the center of the cross-section is approximately the center of the second filter 32, and the direction of the straight line passing through the center of the circle is the radial direction of the second bracket assembly. It should be noted that the second filter 32 has a certain processing dimensional error, therefore, the distance between the mounting member 3311 and the second filter 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 32, so that the flexible member can contact various positions of the second filter as much as possible, thereby improving the cleanliness of the second filter self-cleaning.

In some embodiments, as shown in FIG19 , 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 plurality of scrapers 331 have the same inclination direction. The number of the scrapers 331 can be two, three, four, etc., and the embodiment of the present application does not limit the number of scrapers 331. In the embodiment shown in FIG9 , two scrapers 331 are arranged at intervals around the circumference of the inner side of the second filter screen 32, wherein the two scrapers 331 are inclined at a set angle relative to the vertical direction, and the two scrapers have the same inclination direction. It should be noted that the same inclination direction means that during the rotation of the second bracket assembly 33, the two inclined scrapers 331 have the same disturbing effect on the solid or liquid in the receiving chamber. For example, during the rotation of the second bracket assembly, the two scrapers 331 have the effect of accelerating the sedimentation of the solid in the receiving chamber.

In some embodiments, as shown in FIG. 19 , the second bracket assembly 33 further includes a transmission shaft 332 and a connector 333. The transmission shaft 332 extends in the vertical direction, and 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 connector 333 connects the transmission shaft 332 and the mounting member 3311. The transmission shaft 332 drives the connector 333 to rotate, and the connector 333 drives the scraper 331 to rotate. The embodiment of the present application is conducive to reducing the difficulty of assembling the bracket driving device and the scraper by configuring the second bracket assembly as a transmission shaft and a connector. In the case where multiple scrapers are provided, the multiple scrapers are all connected to the same transmission shaft through the connector 333, thereby reducing the assembly structure of the entire second bracket assembly.

In some embodiments, as shown in FIG10 , the second filter assembly 3 further includes a filter frame 35. The filter frame 35 is disposed outside the second filter 32, and the filter frame 35 connects the second filter 32 and the first housing 37. The second filter 32 is fixed by the filter frame 35. In some embodiments, a fixing block may be disposed at the bottom end of the filter frame 35, and the fixing of the second filter to the first housing is achieved by means of a snap connection or a threaded connection between the fixing block and the first housing 37.

In some embodiments, as shown in FIG. 2 and FIG. 10 , the separator 100 further includes a flow guide 5 . A drainage channel 51 extending in the horizontal direction is provided inside the drainage member 5, and the drainage channel 51 is connected to the second water outlet 31 and the water outlet channel 41. In the embodiment of the present application, a drainage member connecting the second filter assembly and the water outlet member is provided, and the drainage member can guide the filtered liquid in the second filter assembly to the water outlet member, which is conducive to improving the assembly convenience of the second filter assembly and the first filter assembly, and can also guide and merge the liquid.

In some embodiments, as shown in FIG. 11 , the second filter assembly 3 further includes a drain channel 36, one end of which is in communication with the accommodating chamber 321, and the other end of the drain channel 36 is provided with a drain port 361, and the drain port 361 is in communication with the outside of the separator. Specifically, a drain valve may be provided in the drain channel 36, and the drain valve may be controlled to control the opening state of the drain port 361. When the separator 100 is provided in a dishwasher, the drain port 361 may be in communication with the outside of the dishwasher, so as to discharge the solid residue in the accommodating chamber to the outside of the dishwasher.

The whole cyclone separation process is described below by taking the separator 100 applied to a dishwasher as an example in conjunction with FIGS. 5 to 11. The dishwasher uses liquid to wash the residue on the surface of the bowl to clean the bowl. The liquid after washing the bowl contains solid residue, which is not conducive to the recycling of the liquid. The separator can be used to separate the fluid after washing, filter out the solid residue in the fluid, and the separated liquid can be used to wash the bowl again, thereby reducing the secondary contamination of the bowl by the residue. As shown in FIG5 , the direction indicated by the arrow represents the direction of fluid movement. The upper end of the water cup 1 receives the liquid mixed with solid residues, and the solid-liquid mixed fluid enters the water inlet chamber 11. The water inlet chamber 11 can play a certain storage role for the fluid. The fluid in the water inlet chamber 11 enters the first vortex channel 2121 from the vortex inlet 2122. Since the first vortex channel is rotated around the first direction (vertical to the paper direction shown in FIG5 ), the fluid mixed with liquid and solid performs a rotational motion under the structural restriction of the vortex component 210. The solid in the fluid is thrown toward the wall direction of the vortex volute 212 because the inertial centrifugal force is greater than that of the liquid. As shown in FIG8 , the first vortex channel 211 is arranged in the vortex channel 211. The filter screen 22 can guide the liquid in the swirl channel 211 into the first water passage 221, and block the solid residue in the swirl channel 211 between the first filter screen 22 and the swirl housing 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 by the dishwasher; a small part of the liquid remains in the first filter screen 22 and continues to move in the first direction (from right to left in Figure 8) along the first water passage 221. As shown in Figure 8, the liquid can drive the solid residue to move in the direction of the swirl outlet 2132, and discharge the residue and a small amount of liquid into the second filter assembly through the swirl outlet 2132. Figure 6 shows a schematic diagram of the residue and a small amount of liquid entering the second filter assembly 3 from the second sub-cavity 2134. As shown in Figure 6, the fluid in the second sub-cavity 2134 enters the accommodating cavity 321 from the bottom of the second filter assembly 3. As shown in FIG9 , the liquid entering the receiving chamber passes through the second filter screen 32 and enters the water outlet chamber 311, and the solid residue is retained in the receiving chamber 321. As shown in FIG10 , the liquid in the water outlet chamber 311 flows from the drainage channel 51 to the water outlet channel 41, and finally is discharged from the third water outlet 42 for recycling by the dishwasher. As shown in FIG11 , the solid residue in the receiving chamber 321 is discharged to the sewage discharge channel 36, and then discharged to the outside of the dishwasher through the sewage discharge port 361, thereby achieving the separation of solid and liquid.

The present application also provides a cleaning device, as shown in FIG20 , which can be used to clean the The cleaning device is a dishwasher, a washing machine, and the like. The cleaning device is set as a dishwasher as an example for explanation in the embodiment of the present application. The cleaning device includes a separator 100 and a cleaning shell 200 according to any of the above embodiments. An isolated cleaning chamber 201 and a separation chamber 202 are provided inside the cleaning shell 200. Isolation means that the cleaning chamber 201 and the separation chamber 202 are separated from each other and are not connected to each other. Only through a specific pipe can the cleaning chamber 201 and the separation chamber 202 be connected. The cleaning chamber 201 in the embodiment of the present application is used to accommodate objects to be cleaned. For example, the cleaning chamber 201 can be used to accommodate tableware 300 such as plates, bowls, and chopsticks. The separator 100 is arranged in the separation chamber 202. The cleaning shell 200 is also provided with an inlet pipe 203 and an outlet pipe 204. The inlet pipe 203 connects the cleaning chamber 201 with the cyclone inlet of the separator 100, and the outlet pipe 204 connects the third water outlet of the separator 100 with the cleaning chamber 201.

As shown in Figure 20, the inlet pipe 203 can be connected to the water cup, and the outlet pipe 204 can be connected to the water outlet channel. The working process of the dishwasher is described below:

As shown in Figure 20, the tableware 300 to be washed is placed in the cleaning chamber 201, and the clean liquid impacts the surface of the tableware 300 and washes away the residue on the surface of the tableware 300 to form a solid-liquid mixture with residue. In order to improve the cleanliness of the tableware 300, the tableware 300 needs to be rinsed multiple times, so that the solid-liquid mixture needs to be separated to form a liquid without residue. After the liquid is processed, it is circulated to rinse the tableware 300. As shown in Figure 5, after rinsing the tableware 300, the solid-liquid mixture flows to the bottom plate 206, and then is guided to the water inlet chamber 11 through the inlet pipe 203, and then the solid-liquid mixture in the water inlet chamber 11 is 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 (refer to Figure 10) through the first water outlet 21, and the remaining liquid flushes the solids screened out by the first filter screen into the second filter component; as shown in Figure 9, the second filter component can collect solid residues and guide the remaining liquid into the water outlet chamber 311, and the remaining liquid then flows into the water outlet channel 41 (refer to Figure 10) through the water outlet chamber 311. The liquid discharged from the water outlet chamber 311 merges with the liquid discharged from the first water outlet, and finally circulates to the cleaning chamber 201 from the third water outlet 42 for circulating rinsing of the tableware 300.

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 quickly flow into the outlet pipe, so as to improve the efficiency of the circulating liquid diversion.

In some embodiments, as shown in Figure 16, the outlet pipe 204 includes a lower spray arm 207, a middle spray arm 208 and an upper spray arm 209, and the lower spray arm 207, the middle spray arm 208 and the upper spray arm 209 are interconnected through a pipe 2072, and the lower spray arm 207, the middle spray arm 208 and the upper spray arm 209 are spaced apart in the vertical direction of the cleaning chamber 201. Of course, in other embodiments, the lower spray arm 207, the middle spray arm 208 and the upper spray arm 209 can be spaced apart in other directions of the cleaning chamber 201, and the tableware 300 in the cleaning chamber 201 can be arranged in multiple rows. By setting the lower spray arm 207, the middle spray arm 208 and the upper spray arm 209, each spray arm is arranged opposite to a row of tableware, which is convenient for accurate flushing of the tableware and is beneficial to improving the cleaning degree of the dishes. As shown in FIG20 , the lower spray arm 207, the middle spray arm 208 and the upper spray arm 209 are all provided with a plurality of nozzles 2071 in the horizontal direction. The nozzles 2071 are used to introduce 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 chamber 201. The nozzles 2071 are beneficial to the area of the liquid in the cleaning cavity, thereby improving the cleanliness of the dishes in the cleaning cavity. The above is only a preferred embodiment of the present application, and is not intended to limit the protection scope of the present application.
