[0010] In some embodiments, the first filter assembly further includes: an inner cylinder, which is hollow inside and disposed within the first water passage, wherein one end of the inner cylinder in the first direction is connected to the first water outlet, and the other end of the inner cylinder in the first direction is connected to the first water passage.

[0011] In some embodiments, the first filter assembly further includes: a filter drive device connected to the first filter to drive the first filter to rotate about the first direction; and a first support assembly fixed between the vortex assembly and the first filter, wherein the first support assembly is at least partially in contact with the first filter.

[0015] In some embodiments, the separator further includes a diversion element having a diversion channel extending horizontally inside, the diversion channel connecting the second outlet and the outlet channel.

[0016] This invention also provides a cleaning device, comprising: a separator according to any one of the preceding claims; a cleaning housing having an isolated cleaning chamber and a separation chamber inside, the cleaning chamber being used to accommodate an object to be cleaned, the separator being disposed within the separation chamber; the cleaning housing further comprising an inlet pipe and an outlet pipe, the inlet pipe connecting the cleaning chamber and the water inlet chamber, and the outlet pipe connecting the third water outlet and the cleaning chamber.

[0017] This invention provides a separator and cleaning device. The separator includes a water cup, a first filter assembly, a second filter assembly, and a water outlet. The water cup has an inlet chamber that connects to the outside of the separator. The first filter assembly is connected to the water cup and has a first outlet. The first filter assembly has a vortex channel and a first filter screen that are rotatably arranged around a first direction inside. The first filter screen guides liquid passing through the vortex channel into the first filter screen. The first outlet connects to the inside of the first filter screen. The second filter assembly is located outside the water cup and is connected to the first filter assembly.

The first filter assembly contains a swirling channel rotating in a first direction and a first filter screen. A mixture of solids and liquids enters the swirling channel. Under the action of inertial centrifugal force, solids with a density much greater than that of the liquid can move radially away from the first filter screen. Solids with a density slightly greater than that of the liquid, even if they cannot be separated from the liquid by inertial centrifugal force, are blocked by the first filter screen, allowing only the liquid to enter the first filter screen. Some of the liquid remaining outside the first filter screen can carry the solids to the second filter assembly. The second filter screen traps solids inside, while liquid flows from inside the second filter screen to the second outlet outside. The second filter assembly is positioned outside the water cup, allowing it to operate independently. The design size and structure of the water cup are not limited by the second filter assembly, simplifying its design and avoiding nesting with other components. This reduces the manufacturing and assembly difficulty of the separator, and the more flexible cup size allows for better control of the inflow. A smaller cup size also reduces the fluid velocity introduced into the separator, thus saving water. The liquid filtered by the first and second filter components is combined and discharged through the outlet, increasing the outflow rate and simplifying the separator's liquid discharge structure.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0042] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0043] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0044] This invention provides a separator that can be applied to cleaning equipment such as washing machines, dishwashers, and fruit and vegetable cleaners. It should be noted that the application scenarios of this invention do not limit the type of separator used in this invention.

[0045] The following description uses the application of a separator in a dishwasher as an example. The separator in this embodiment of the invention can separate a mixture of solids and liquids into separate liquids or separate solids.

[0046] This invention provides a separator 100, such as... Figure 1 and Figure 2 As shown, the separator 100 includes a water cup 1, a first filter assembly 2, a second filter assembly 3, and a water outlet 4. Among them, Figure 1 The figure shown is a perspective view of the separator 100 according to an embodiment of the present invention. Figure 2The figure shown is an exploded view of the separator 100 according to an embodiment of the present invention. The water cup 1 has a water inlet chamber 11 inside, and one end of the water inlet chamber 11 is open in the vertical direction. It should be noted that the vertical direction mentioned in the embodiment of the present invention refers to the up and down direction in the absolute coordinate system. The water inlet chamber 11 is connected to the outside of the separator 100. In the scenario where 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. The fluid can be introduced into the water inlet chamber 11 through the upper end of the water cup 1.

[0047] like Figure 1 As shown, the first filter assembly 2 is connected to the water cup 1. The first filter assembly 2 has a first outlet 21. After the fluid is introduced into the inlet chamber 11 from the upper end of the water cup 1, the fluid in the inlet chamber 11 can flow into the first filter assembly 2. The first filter assembly 2 is used to guide the fluid in the inlet chamber 11 to spiral motion, so as to separate at least a portion of the liquid in the fluid to the first outlet 21. It should be noted that the spiral motion means that the fluid entering the first filter assembly 2 from the inlet chamber 11 can rotate spirally in a first direction. The spirally moving fluid will be subjected to centrifugal force. Since the density of solids in the fluid is greater than that of liquids, the centrifugal force on solids in the fluid is greater than that on liquids, so that most of the solids and liquids in the fluid can be separated in the first filter assembly 2. The first outlet 21 in the first filter assembly 2 is used to discharge the liquid separated in the first filter assembly 2.

[0048] Combination Figure 1 and Figure 2 As shown, the second filter component 3 is disposed outside the water cup 1. It should be noted that "outside the water cup 1" means that the second filter component 3 and the water cup 1 do not have a positional overlap.

[0049] In this embodiment of the invention, the second filter assembly 3 is connected to the first filter assembly 2. The first filter assembly 2 introduces unfiltered fluid into the second filter assembly 3. That is, the first filter assembly 2 filters the liquid out of the fluid and exits it from the first outlet 21. The remaining solids and liquids are introduced into the second filter assembly 3 for filtration. The second filter assembly 3 is provided with a second outlet 31. The second filter assembly 3 filters the fluid introduced from the first filter assembly 2, retains all solids in the fluid in the second filter assembly 3, and exits the liquid in the fluid from the second outlet 31.

[0050] like Figure 2 As shown, in this embodiment of the invention, a water outlet 4 is provided. The water outlet 4 is used to combine the liquid from the first water outlet 21 and the second water outlet 31, and then discharge it uniformly from the third water outlet 42 of the water outlet 4 for recycling by the cleaning equipment. Figure 10 for Figure 7The EE section view in the figure illustrates the connection relationship between the water outlet 4 and the first water outlet 21 and the second water outlet 31, combined with Figure 10 As shown, the water outlet component 4 has an internal water outlet channel 41, which connects the first water outlet 21 and the second water outlet 31. The water outlet component 4 also has a third water outlet 42 connected to the water outlet channel 41. This water outlet component 4 can be understood as a three-way pipe; that is, the water outlet component 4 connects the first water outlet 21 and the second water outlet 31 via the water outlet channel 41. Liquid filtered in the first filter assembly 2 can be introduced into the water outlet channel 41 from the first water outlet 21, and liquid filtered in the second filter assembly 3 can be introduced into the water outlet channel 41 from the second water outlet 31. The liquids introduced from the first water outlet 21 and the second water outlet 31 converge in the water outlet channel 41 and are then discharged from the third water outlet 42.

[0051] This invention provides a separator and cleaning device. The separator includes a water cup, a first filter assembly, a second filter assembly, and a water outlet. The water cup has an inlet chamber that connects to the outside of the separator. The first filter assembly is connected to the water cup and has a first outlet. The first filter assembly has a vortex channel and a first filter screen that are rotatably arranged around a first direction inside. The first filter screen guides liquid passing through the vortex channel into the first filter screen. The first outlet connects to the inside of the first filter screen. The second filter assembly is located outside the water cup and is connected to the first filter assembly. The second filter assembly has a second filter screen inside and a second outlet that connects to the outside of the second filter screen. The second filter screen guides liquid introduced from the first filter assembly to the second outlet. The water outlet discharges the liquid introduced from the first and second outlets through a third outlet. This invention embodiment includes a first filter assembly and a second filter assembly. The first filter assembly contains a swirling channel rotating in a first direction and a first filter screen. A mixture of solids and liquids enters the swirling channel. Under the action of inertial centrifugal force, solids with a density much greater than that of the liquid can move radially away from the first filter screen. Solids with a density slightly greater than that of the liquid, even if they cannot be separated from the liquid by inertial centrifugal force, are blocked by the first filter screen, allowing only the liquid to enter the first filter screen. Some of the liquid remaining outside the first filter screen can carry the solids to the second filter assembly. The second filter screen traps solids inside, while liquid flows from inside the second filter screen to the second outlet outside. The second filter assembly is positioned outside the water cup, allowing it to operate independently. The design size and structure of the water cup are not limited by the second filter assembly, simplifying its design and avoiding nesting with other components. This reduces the manufacturing and assembly difficulty of the separator, and the more flexible cup size allows for better control of the inflow. A smaller cup size also reduces the fluid velocity introduced into the separator, thus saving water. The liquid filtered by the first and second filter components is combined and discharged through the outlet, increasing the outflow rate and simplifying the separator's liquid discharge structure.

[0052] In some embodiments, such as Figure 3 As shown, the first filter assembly 2 includes a vortex assembly 210 and a first filter screen 22. Combined with... Figure 4 and Figure 5 As shown, the vortex assembly 210 has a vortex channel 211 extending horizontally inside, and the first filter screen 22 is at least partially disposed inside the vortex assembly 210. The vortex assembly 210 has a vortex channel 211 extending horizontally around the first direction (…). Figure 5The swirling channel 211, shown in the direction perpendicular to the paper, is rotatably configured. This rotatable configuration indicates that the fluid flowing through the swirling channel 211 forms a swirling flow, rather than simply moving in a straight line. The swirling channel 211 has a first direction (…). Figure 5 The swirl inlet 2122 and swirl outlet 2132 (as shown in the direction perpendicular to the paper) are spaced apart (refer to...) Figure 8 (as shown), Figure 5 The direction of the middle arrow indicates the direction of fluid movement. The inlet chamber 11 is connected to the vortex inlet 2122, which is used to introduce the fluid to be separated into the vortex channel 211. Figure 8 As shown, the cyclone outlet 2132 is used to discharge the solids or solid-liquid mixture separated within the cyclone channel 211. In the case where the separator 100 is used in a dishwasher, the solids may be food residue, etc. It should be noted that the first direction described in this embodiment of the invention is located in the horizontal direction, which refers to the direction of the horizontal plane in the absolute coordinate system. Figure 8 The left and right directions shown can be used to indicate the first direction.

[0053] In this embodiment of the invention, 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 be roughly formed into a cylindrical structure, and the area of ​​the first filter screen 22 represents the lateral surface area of ​​the cylinder it forms. Similarly, the second filter screen 32 can also be roughly formed into a cylindrical structure, and the area of ​​the second filter screen 32 represents the lateral surface area of ​​the cylinder it forms. This area can be used to represent the water throughput of the first or second filter screen; the larger the area, the greater the water throughput. In this embodiment of the invention, 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 provided on the first filter screen 22 is greater than the number of second through holes that can be provided on the second filter screen 32. Therefore, the water throughput of the first filter screen is greater than that of the second filter screen. Furthermore, the first filter screen 22 is closer to the water inlet chamber 11 than the second filter screen 32. Therefore, the resistance of the liquid flowing out from the first filter screen 22 is less than the resistance of the second filter screen 32. As a result, most of the liquid passes through the first filter screen 22 and flows out to the first outlet 21. The remaining small portion of liquid carries the solids blocked on the outside of the first filter screen 22 and washes them to the second filter assembly. The remaining small portion of liquid flows through the second filter screen to the second outlet 31.

[0054] like Figure 5As shown, the vortex channel 211 connects to the bottom of the water inlet chamber 11. It should be noted that "bottom" refers to the lower part of the water inlet chamber 11 in the absolute coordinate system. That is, the vortex inlet 2122 connects to the lower end of the water inlet chamber 11. This can be understood as the distance between the vortex inlet 2122 and the bottom of the water inlet chamber 11 being less than or equal to a set value, which can be zero. In this embodiment of the invention, by connecting the vortex channel to the bottom of the water inlet chamber, even when the water volume in the water inlet chamber is low, the vortex inlet can still guide the fluid from the bottom of the water inlet chamber into the vortex channel. This reduces the water inlet height of the vortex channel, making it less likely for air in the water inlet chamber to enter the vortex channel from the vortex inlet, and also making it less prone to air suction in the vortex channel.

[0055] like Figure 7 and Figure 8 As shown, a first filter screen 22 is disposed within a vortex channel 211. The first filter screen 22 has a first water passage 221 extending horizontally inside. The first filter screen 22 is at least disposed within the vortex channel 211; this means it can be completely disposed within the vortex channel 211, or partially disposed within and partially disposed outside the vortex channel 211. The first filter screen 22 has a first water passage 221 extending in a first direction, where the direction of extension represents the maximum dimension (length) of the first water passage 221. The first water passage 221 communicates with the vortex channel 211. The first filter screen 22 guides the liquid passing through the vortex channel 211 into the first water passage 221 and blocks solids passing through the vortex channel 211, thus retaining the solids between the first filter screen 22 and the vortex assembly 210. Figure 8 As shown, the first water outlet 21 is located 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 by the first water outlet 21 can be recycled by the dishwasher.

[0056] In this embodiment of the invention, the vortex channel is rotated around a first direction, and a first filter screen is disposed within 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 the liquid can move radially away from the first filter screen. Solids with a density slightly greater than that of the liquid, even if they cannot be separated from the liquid by inertial centrifugal force, can only enter the first water passage under the obstruction of the first filter screen. Some of the liquid remaining between the first filter screen and the vortex assembly can carry the solids to continue flowing to the vortex outlet. The solids and a small amount of liquid are discharged to the second filter assembly at the vortex outlet, which helps to improve the efficiency of liquid separation. Furthermore, the solids will not remain in the vortex channel and block the first filter screen, which helps to improve the smoothness of the liquid in the first water passage and facilitates the recycling of the liquid.

[0057] In some embodiments, such as Figure 3 , Figure 5 and Figure 8 As shown, the swirl assembly 210 includes a swirl volute 212 and a swirl outer shell 213. (As...) Figure 5 As shown, the vortex volute 212 forms a ring around the first direction ( Figure 5 The first vortex channel 2121 (perpendicular to the plane of the paper) rotates, and the first vortex channel 2121 has a vortex inlet 2122 in the circumferential direction. It should be noted that the circumferential direction is the direction surrounding the first direction. The vortex shell 213 forms a vortex inlet 2122 inside the first direction (perpendicular to the plane of the paper). Figure 8 The second vortex channel 2131 extends in the left-right direction (as shown), and the direction of extension of the second vortex channel 2131 indicates the direction of its maximum size. The second vortex channel 2131 extends to one end in the first direction (…). Figure 8 The right end shown is connected to the first vortex channel 2121, and the other end of the second vortex channel 2131 (shown on the right) is connected to the first vortex channel 2121. 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.

[0058] In some embodiments, such as Figure 8 As shown, the first filter assembly 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 extends 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.

[0059] 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. The first through-hole can be a cylindrical hole, in which case its diameter represents the diameter of a circle. Of course, the cross-section of the first through-hole can also be set to an irregular shape, such as an ellipse, triangle, or square. When the cross-section of the first through-hole is set to an irregular shape, its diameter can be represented by the diameter of a standard circle with equal area. By setting the diameter of the first through-hole within a certain range, this embodiment of the invention enables the first through-hole to filter out 99% of the solids in the fluid, which can be considered as a first filter screen that almost completely separates the solids and liquids in the fluid.

[0060] like Figure 8 As shown, in this embodiment of the invention, the first filter screen 22 extends from the first vortex channel 2121 along a first direction to the second vortex channel 2131. A fluid mixed with solids and liquids enters the first vortex channel 2121 from the vortex inlet 2122. Some of the liquid can pass through the first filter screen 22 located in the first vortex channel 2121 and enter the first water passage channel 221. The remaining fluid can continue to flow into the second vortex channel 2131. After the fluid enters the second vortex channel 2131, some of the liquid passes through the first filter screen 22 located in the second vortex channel 2131 and enters the first water passage channel 221. The remaining small portion of liquid can drive the solids to continue moving along the first direction, so as to drive the solids to be discharged from the vortex outlet 2132. This reduces the risk of solids clogging the first filter screen 22 and improves the smoothness of the liquid in the first water passage channel. The first filter screen extends into the first vortex channel, improving fluid filtration efficiency. The first filter screen also extends into the second vortex channel. The direction of the first filter screen's extension in the second vortex channel is not the same as the original flow direction of the fluid in the first vortex channel. The first filter screen in the second vortex channel can rectify the fluid flow, significantly reducing the vortex intensity of the liquid entering the first water passage, thus greatly reducing the resistance of the entire separator and improving the stability of the separator structure. Furthermore, the longer length of the first filter screen contributes to improved filtration efficiency.

[0061] like Figure 8 As shown, the inner cylinder 223 is hollow and disposed within the first water passage 221. The hollow interior of the inner cylinder 223 can be understood as having openings at both ends in the first direction. One end of the inner cylinder 223 in the first direction is connected to the first water outlet 21, and the other end of the inner cylinder 223 in the first direction is connected to the first water passage 221. The inner cylinder 223 is disposed through the first direction, and one end of the inner cylinder 223 in the first direction ( Figure 8 The right end shown is fixedly connected to the inner wall of the vortex casing 212 and communicates with the first outlet 21, as shown. Figure 8As shown, the inner cylinder 223 is located at the other end in the first direction ( Figure 7 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.

[0062] 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 5 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.

[0063] 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 8As 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.

[0064] In some embodiments, combined with Figure 3 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 8 (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.

[0065] Combination Figure 3 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.

[0066] During the filtration process of the first filter assembly, a small amount of contaminants may still adhere to the first filter screen. In this embodiment of the invention, by setting a first support assembly, during the rotation of the first filter screen 22, since the first support assembly 225 is stationary relative to the vortex assembly, 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 allows the horizontal support assembly to scrape off the contaminants on the first filter screen. Furthermore, the first support assembly 225 and the first filter screen 22 are at least partially in spiral contact, and the fluid in the first filter assembly also moves spirally around a first direction. The spiral contact portion is roughly in the same direction as the movement of the fluid in the first filter assembly, which helps to reduce the interference of the first support assembly on the vortex field in the vortex channel and reduce the risk of channel blockage in the vortex channel.

[0067] In some embodiments, such as Figure 8 As shown, the first filter screen 22 also includes a flow guide 226. The flow guide 226 is disposed within the first water passage 221 and is connected to the filter screen driving device 224. It should be noted that the flow guide 226 can be fixedly connected to the filter screen driving device 224. The embodiments of the present invention do not limit the specific form of connection between the flow guide 226 and the filter screen driving device 224. For example, the flow guide 226 can be permanently connected to the filter screen driving device 224 by welding or integral molding. Alternatively, the flow guide 226 can also be detachably connected to the filter screen driving device 224 by snap-fit ​​or other means, as long as the rotation of the filter screen driving device 224 can drive the flow guide 226 to rotate.

[0068] Among them, such as Figure 8 As shown, the cross-sectional area of ​​the flow guide 226 gradually increases from one end near the vortex volute 212 to the end connected to the filter drive 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 configured as a cone, in which case the cross-section of the flow guide 226 is circular, and therefore can be used... Figure 8 The change in diameter of the guide element 226 in the cross-section shown represents the trend of cross-sectional area change, combined with... Figure 9As 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.

[0069] In some embodiments, such as Figures 12-15 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 8 (as shown) one side. As... Figure 12 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.

[0070] Among them, combined Figure 3 and Figure 5 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 3In this embodiment of the invention, the spiral direction of the vortex channel 211, as indicated by the dashed arrow, is defined as counterclockwise. Correspondingly, the spiral direction of the flexible component 2252 is the same as that of the vortex channel 211; that is, the flexible component 2252 also spirals counterclockwise. By aligning the spiral direction of the vortex channel 211 with that of the flexible component 2252, the fluid entering the vortex channel 211 from the vortex inlet moves in the same direction as the spiral of the flexible component. This reduces the resistance of the flexible component to the fluid movement, thereby improving the spiral motion effect of the fluid within the vortex channel. Furthermore, even with an increase in the thickness of the flexible component, the reduced resistance will not significantly affect the fluid within the vortex channel.

[0071] In some embodiments, such as Figure 13 and Figure 14 As shown, the radial thickness L1 of the flexible component 2252 is greater than the minimum distance L2 between the first filter screen 22 and the fixing frame 2251. Wherein, Figure 14 This diagram shows a cross-sectional view of the first support assembly, which can be approximately circular in shape. The center of this circle is approximately 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 certain dimensional tolerances during manufacturing. Therefore, the distance between the fixing frame 2251 and the first filter screen 22 is not necessarily a fixed value. In this embodiment of the invention, the radial thickness of the flexible member 2252 is set to be greater than the minimum distance between the fixing frame and the first filter screen, allowing the flexible member to contact as many positions as possible of the first filter screen, thereby improving the cleanliness of the first filter screen's self-cleaning function.

[0072] like Figure 12 As shown, the fixing frame 2251 includes a first support 2253. The first support 2253 is fixed to the inner side of the vortex assembly 210. The first support 2253 is spirally arranged around a first direction, and the flexible member 2252 is connected to 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. By spirally arranging the first support around the first direction, the first support can not only stably fix the flexible member, but also help to reduce the obstruction of the first support to the fluid in the vortex channel.

[0073] In some embodiments, such as Figure 12As shown, the fixing frame 2251 also includes a plurality of second supports 2254. The plurality of second supports 2254 are arranged in a ring, spaced apart in a first direction, and each of the second supports 2254 is connected to the first support 2253. At least some of the second supports 2254 are sleeved on the outside of the first filter screen 22. The number of second supports 2254 can be one, two, three, or four, etc. Figure 12 In the embodiment shown, two second supports 2254 are provided. The two second supports 2254 are respectively connected to the two ends of the first support 2253 in the first direction. Both second supports 2254 are sleeved on the outside of the first filter screen 22. The second supports 2254 can play a positioning role for the first filter screen to improve the stability of the movement of the first filter screen.

[0074] In some embodiments, such as Figure 12 As shown, the fixing frame 2251 also includes a third support 2255. The third support 2255 extends along a first direction and connects multiple second supports 2254 and the first support 2253. By providing a third support connecting the first support and the second support, and by having the third support extend along the first direction, this embodiment of the invention helps to improve the structural strength of the first support and the second support, thereby improving the structural stability of the fixing frame.

[0075] In some embodiments, such as Figure 2 and Figure 9 As shown, the second filter assembly 3 includes a first housing 37 and a second filter screen 32. (As indicated...) Figure 9 As shown, the first housing 37 has a water outlet cavity 311 extending vertically inside. It should be noted that the vertical direction refers to the up-down direction in an absolute coordinate system. A second filter screen 32 is disposed within the water outlet cavity 311, and the second filter screen 32 has a receiving cavity 321 communicating with the water outlet cavity 311. Figure 8 As shown, the receiving cavity 321 connects the vortex outlet 2132 and the water outlet cavity 311. The second filter screen 32 guides the liquid between the first filter screen 22 and the vortex assembly 210 to the water outlet cavity 311, while retaining the solids between the first filter screen 22 and the vortex assembly 210 within the receiving cavity 321. The receiving cavity 321 can collect solids from the fluid, facilitating their centralized removal. The liquid in the water outlet cavity 311 can be reintroduced into the dishwasher for reuse.

[0076] The second filter 32 extends vertically. 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 configured as a through-hole structure in the vertical direction, with at least one end of the second filter 32 open in the vertical direction, such as... Figure 9As 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 8 (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.

[0077] In some embodiments, such as Figure 2 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.

[0078] 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 9(See the lower end). It should be noted that "closer" indicates that the two ends of the scraper 331 are relatively close to the two ends of the second filter screen 32 in the vertical direction. By placing the two ends of the scraper close to the two ends of the second filter screen, the scraper rotation can contact as many positions as possible on the second filter screen, thereby increasing the cleaning area of ​​the second filter screen and minimizing the risk of residue clogging on the second filter screen.

[0079] In some embodiments, such as Figure 9 As shown, 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 set direction is greater than or equal to 30 degrees and less than or equal to 60 degrees. The set angle θ can be 30 degrees, 40 degrees, 45 degrees, 50 degrees, and 60 degrees, etc. By limiting the set angle of the scraper within a certain range, this embodiment of the invention can both increase the settling speed of solids in the receiving cavity and reduce the interference effect on the flow of liquid in the receiving cavity, thereby improving the efficiency of liquid flowing from the receiving cavity to the outlet cavity.

[0080] In some embodiments, such as Figure 10 As shown, 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, and the flexible member 2252 is positioned along the extending direction of the mounting member 3311, and is fixed to the side of the mounting member 3311 near the second filter screen 32. The flexible member 2252 represents a component made of a material with low hardness; in this embodiment, the flexible member can be rubber or a brush, etc. By using a material with low hardness for the flexible member, it is beneficial to improve the fit between the flexible member 2252 and the second filter screen 32, thereby improving the cleaning efficiency of the second filter screen 32 and reducing the resistance of the second filter screen 32 to the flexible member, thus reducing the energy consumption for driving the second filter screen 32 to rotate. Furthermore, using a flexible member with low hardness is beneficial for adapting to the second filter screen 32, which may have low processing precision or roundness, allowing the flexible member to contact the second filter screen 32 as much as possible, thereby improving the cleanliness of the second filter screen 32. In this embodiment of the invention, the mounting component 3311 provides support and fixation for the flexible component 2252.

[0081] Among them, such as Figure 17 and Figure 18 As shown, the radial thickness L3 of the flexible member 2252 is greater than the minimum distance L4 between the mounting member 3311 and the second filter screen 32. Wherein, Figure 18This diagram shows a cross-sectional view of the second support assembly, which can be approximately circular in shape. The center of this circle 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 support assembly. It should be noted that the second filter screen 32 has certain dimensional tolerances; therefore, the distance between the mounting member 3311 and the second filter screen 32 is not necessarily a fixed value. In this embodiment of the invention, the radial thickness of the flexible member 2252 is set to be greater than the minimum distance between the mounting member 3311 and the second filter screen 32, allowing the flexible member to contact as many positions as possible of the second filter screen, thereby improving the self-cleaning efficiency of the second filter screen.

[0082] In some embodiments, such as Figure 19 As shown, the second support assembly 33 includes a plurality of scraper blades 331, which are circumferentially spaced around the inner side of the second filter screen 32, and the scraper blades 331 have the same inclination direction. The number of scraper blades 331 can be two, three, or four, etc. This embodiment of the invention does not limit the number of scraper blades 331. Figure 9 In the illustrated embodiment, two scraper blades 331 are provided. The two scraper blades 331 are arranged circumferentially around the inner side of the second filter screen 32. The two scraper blades 331 are inclined at a set angle relative to the vertical direction, and the two scraper blades are inclined in the same direction. It should be noted that the same inclination direction means that during the rotation of the second support assembly 33, the two inclined scraper blades 331 have the same disturbance effect on the solid or liquid in the receiving cavity. For example, during the rotation of the second support assembly, the two scraper blades 331 both play a role in accelerating the settling of solids in the receiving cavity.

[0083] In some embodiments, such as Figure 19 As shown, the second support assembly 33 also includes a drive shaft 332 and a connector 333. The drive shaft 332 extends vertically, and one end of the drive shaft 332 is connected to the support drive device 34, which can drive the drive shaft 332 to rotate. The connector 333 connects the drive shaft 332 and the mounting member 3311. The drive shaft 332 drives the connector 333 to rotate, and the connector 333 drives the scraper 331 to rotate. By configuring the second support assembly as a drive shaft and a connector, this embodiment of the invention helps to reduce the assembly difficulty of the support drive device and the scraper. When multiple scrapers are provided, all scrapers are connected to the same drive shaft through the connector 333, reducing the overall assembly structure of the second support assembly.

[0084] In some embodiments, such as Figure 10As 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.

[0085] In some embodiments, such as Figure 2 and Figure 10 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 from the second filter assembly to the outlet, which not only improves the ease of assembly between the second and first filter assemblies but also enables the guidance and merging of the liquid.

[0086] In some embodiments, such as Figure 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.

[0087] The following combination Figures 5-11 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 5 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, disposed within the vortex channel 211, guides the liquid within the vortex channel 211 into the first water passage channel 221, while blocking solid residue within the vortex channel 211 between the first filter screen 22 and the vortex housing 213. Most of the liquid passes through the first filter screen 22 into the first water passage channel 221 and flows out through the first outlet 21 for recycling by the dishwasher; a small portion of the liquid remains on the first filter screen 22 and continues along the first water passage channel 221 in the first direction (…). Figure 8 Movement from right to left (as in the middle), such as Figure 8 As shown, the liquid can carry the solid residue toward 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 The diagram shows residue and a small amount of liquid entering the second filter assembly 3 from the second sub-cavity 2134. Figure 6 As shown, fluid in the second sub-cavity 2134 enters the receiving cavity 321 from the bottom of the second filter assembly 3. As... Figure 9 As shown, the liquid entering the receiving cavity passes through the second filter screen 32 and enters the outlet cavity 311, while solid residue remains in the receiving cavity 321; as Figure 10 As shown, the liquid in the water outlet chamber 311 flows from the drainage channel 51 to the water outlet channel 41, and finally exits from the third water outlet 42 for recycling by the dishwasher. Figure 11 As shown, solid residue in the receiving cavity 321 is discharged to the drain channel 36, and then discharged to the outside of the dishwasher through the drain port 361, thereby achieving the separation of solids and liquids.

[0088] This invention also provides a cleaning device, such as... Figure 20 As shown, the cleaning device can be a dishwasher or washing machine, etc. This embodiment of the invention uses a dishwasher as an example. The cleaning device includes a separator 100 and a cleaning housing 200 as described in any of the above embodiments. The cleaning housing 200 has isolated cleaning chambers 201 and separation chambers 202 inside. Isolation means that the cleaning chambers 201 and 202 are separated and not connected to each other; they can only be connected via a specific pipe. In this embodiment, the cleaning chamber 201 is used to hold the object to be cleaned. For example, the cleaning chamber 201 can hold tableware 300 such as plates, bowls, and chopsticks. The separator 100 is disposed inside the separation chamber 202. The cleaning housing 200 also has an inlet pipe 203 and an outlet pipe 204. The inlet pipe 203 connects the cleaning chamber 201 to the vortex inlet of the separator 100, and the outlet pipe 204 connects the third outlet of the separator 100 to the cleaning chamber 201.

[0089] Combination 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:

[0090] like Figure 20 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 5 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 10 The remaining liquid flushes the solids filtered out by the first filter into the second filter assembly; for example... Figure 9 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 10 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.

[0091] 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.

[0092] In some embodiments, such as Figure 16 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. Figure 20As shown, the lower spray arm 207, the middle spray arm 208, and the upper spray arm 209 are all provided with multiple nozzles 2071 in the horizontal direction. The nozzles 2071 are 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 chamber 201. By providing multiple nozzles 2071, the area of ​​liquid rinsing in the cleaning chamber is increased, thereby improving the cleanliness of the tableware in the cleaning chamber.
