DETAILED DESCRIPTION

[0061] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present 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 only used to explain the present invention and are not intended to limit the present invention.

[0062] The various specific technical features described in the specific embodiments may be combined in any suitable manner, unless they are inconsistent. For example, different embodiments and technical solutions may be formed by combining different specific technical features. To avoid unnecessary repetition, the various possible combinations of the specific technical features in the present invention will not be described separately.

[0063] In the following description, the terms "first, second, ..." are used solely to distinguish different objects and do not imply any similarities or connections between the objects. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to directions during normal use. The directions "left" and "right" refer to the left-right directions shown in the corresponding schematic diagrams, which may or may not be the left-right directions during normal use.

[0064] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising that element. "A plurality" means greater than or equal to two.

[0065] The embodiment of the present invention provides a separator that can be applied to cleaning appliances such as washing machines and dishwashers. It should be noted that the application scenario type of the embodiment of the present invention does not limit the separator of the embodiment of the present invention.

[0066] The separator is described below by taking its application in a dishwasher as an example. The separator in the embodiment of the present invention can separate a mixed fluid containing solids and liquids into separate liquids or separate solids.

[0067] like Figure 1-Figure 4 As shown, the separator 1 includes a cyclone component 2 and a first filter component 3. Figure 1 and Figure 2 is a three-dimensional diagram of the separator, Figure 3 This is the main view of the separator. Figure 4 for Figure 3 Sectional view of the middle AA section. Figure 4 As shown, the first filter assembly 3 is at least partially disposed in the cyclone assembly 2, and the cyclone assembly 2 is provided with a first direction ( Figure 4 The swirl channel 21 is arranged in a rotating manner (in the left and right directions shown). The rotating arrangement means that the liquid can form a rotating flow fluid when passing through the swirl channel 21, rather than just moving in a straight line. The swirl channel 21 has a first direction ( Figure 4 The swirl inlet 22 and the swirl outlet 23 are spaced apart in the left and right directions as shown. The swirl inlet 22 is used to introduce the fluid to be separated into the swirl channel 21. Figure 5 As shown, the swirl outlet 23 is used to discharge the solid or solid-liquid mixture separated in the swirl channel 21. When the separator 1 is used in a dishwasher, the solid can be food residues, etc. It should be noted that the first direction described in the embodiment of the present invention is in the horizontal direction. The horizontal direction represents the direction of the horizontal plane in the absolute coordinate system, and the horizontal direction can be parallel to the horizontal plane. Figure 4 The paper direction is shown. Figure 4 The left and right directions shown may be used to represent a first direction.

[0068] like Figure 4As shown, the first filter assembly 3 is at least arranged in the vortex channel 21. Being at least arranged in the vortex channel 21 means that the first filter assembly 3 can be completely arranged in the vortex channel 21, or a part of it can be arranged in the vortex channel 21, and the other part of it can be arranged outside the vortex channel 21. A first water passage 31 extending along a first direction is provided inside the first filter assembly 3. The extending direction of the first water passage 31 represents the maximum dimension direction (length direction) of the first water passage 31. The first water passage 31 is connected to the vortex channel 21, and the first filter assembly 3 is used to guide the liquid passing through the vortex channel 21 into the first water passage 31, and to block the solids passing through the vortex channel 21, so that the solids passing through the vortex channel 21 are retained between the first filter assembly 3 and the vortex assembly 2. Combined Figure 6 and Figure 7 As shown, the first water passage 31 is further provided with a first water outlet 4, which is used to discharge the liquid in the first water passage 31. When the separator 1 is used in a dishwasher, the liquid discharged from the first water outlet 4 can be recycled by the dishwasher.

[0069] Combine Figure 1-Figure 7 As shown in the figure, the following uses the separator in a dishwasher as an example to explain the separation principle of the separator. The dishwasher uses liquid to rinse the residue on the surface of the bowl to clean the bowl. The liquid after rinsing the bowl is mixed with solid residue, which is not conducive to the recycling of the liquid. The separator can be used to separate the fluid after rinsing and filter out the solid residue in the fluid. The separated liquid can be used to rinse the bowl again, thereby reducing the secondary contamination of the bowl by the residue. Figure 1 As shown, the swirl inlet 22 can be used to receive liquid mixed with residue (hereinafter referred to as "fluid"), such as Figure 4 As shown, the direction of the arrow indicates the direction of movement of the fluid. The swirl inlet 22 can introduce the fluid into the swirl channel 21. Since the swirl component 2 is provided with a first direction ( Figure 4 The swirl channel 21 is rotated (left and right directions as shown), and the fluid mixed with liquid and solid performs a rotational motion under the structural limitation of the swirl component 2. The solid in the fluid is thrown toward the wall direction of the swirl component 2 because the inertial centrifugal force is greater than that of the liquid. The first filter component 3 arranged in the swirl channel 21 can guide the liquid in the swirl channel 21 into the first water passage 31, and block the solid residue in the swirl channel 21 between the first filter component 3 and the swirl component 2. Most of the liquid can pass through the first filter component 3 into the first water passage 31 and flow out through the first water outlet 4 for recycling in the dishwasher; a small part of the liquid remains in the first filter component 3 and continues to move in the first direction along the first water passage 31, as shown in FIG. Figure 5As shown, the direction of the arrow represents the direction of movement of the fluid. The liquid can drive the solid residue to move toward the vortex outlet 23, and discharge the residue and a small amount of liquid through the vortex outlet 23, thereby achieving separation of solid and liquid.

[0070] It should be noted that the embodiment of the present invention does not limit to which component the swirl outlet 23 is connected. For example, the swirl outlet 23 can be directly connected to the outside of the dishwasher, and the liquid mixed with residue can be directly discharged through the swirl outlet 23; or the swirl outlet 23 can be connected to other components, and the residue can be collected and discharged in a centralized manner through other components.

[0071] An embodiment of the present invention provides a separator, which includes a vortex component and a first filter component. A vortex channel is provided inside the vortex component and is arranged to rotate around a first direction. The vortex channel has a vortex inlet and a vortex outlet arranged at intervals in the first direction. The first direction is located in the horizontal direction. The first filter component is at least arranged in the vortex channel. A first water flow channel is provided inside the first filter component, and the first water flow channel is provided with a first water outlet. The embodiment of the present invention is to arrange the vortex channel to rotate around a first direction, and the first filter component is arranged in the vortex channel. The mixed fluid mixed with solids and liquid 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 in a direction away from the first filter component. Even if the solids with a density slightly greater than that of the liquid cannot be separated from the liquid by the action of inertial centrifugal force, only the liquid can enter the first water flow channel due to the obstruction of the first filter component. The part of the liquid remaining between the first filter component 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 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 component, which is beneficial to improving the fluidity of the liquid in the first water flow channel and facilitating the recycling of the liquid.

[0072] In some embodiments, as Figure 1 and Figure 2 As shown, the swirl assembly 2 includes a swirl volute 24 and a swirl housing 25. Figure 6 and Figure 7 As shown, the swirl volute 24 is internally formed around the first direction ( Figure 7 The first swirl channel 211 rotates in the left and right directions (shown), and the first swirl channel 211 is provided with a swirl inlet 22 in the circumferential direction. It should be noted that the circumferential direction is the direction surrounding the first direction. The swirl housing 25 is formed inside along the first direction ( Figure 7 The second vortex channel 212 extends in the left and right directions (shown in the left and right directions). The extending direction of the second vortex channel 212 represents the maximum dimension direction of the second vortex channel 212. The second vortex channel 212 is provided at one end ( Figure 7The left end shown in FIG2 is connected to the first vortex channel 211, and the other end of the second vortex channel 212 ( Figure 7 The second swirl channel 212 is provided with a swirl outlet 23 at the right end (as shown). It should be noted that the other end of the second swirl channel 212 represents the position of the second swirl channel 212 away from the first swirl channel 211. The swirl outlet 23 is not located at the rightmost end of the second swirl channel 212 in the first direction. The swirl outlet 23 can also be located within a certain range from the rightmost end. In this embodiment of the present invention, the first swirl channel 211 and the second swirl channel 212 together form the swirl channel 21. By setting a first vortex channel rotating around a first direction in the vortex volute, the fluid passing through the first vortex channel can utilize inertial centrifugal force to achieve separation of solids and liquids, so that most of the liquid can enter the first water passage channel. By setting a second vortex channel extending along the first direction in the vortex housing, since the first filter assembly and the second vortex channel both extend along the first direction, which is different from the direction of liquid flow in the first vortex channel, the direction of the liquid will change after the liquid enters the second vortex channel, which plays a rectifying role. Part of the liquid can enter the first water passage, and the liquid in the first water passage can be discharged through the first water 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 move to the vortex outlet to achieve solid screening.

[0073] In some embodiments, as Figure 7 As shown, the first filter assembly 3 includes a first filter screen 32. A first water passage 31 is formed inside the first filter screen 32. The first water passage 31 is along the first direction ( Figure 7 In the embodiment of the present invention, the first filter screen 32 extends from the first swirl channel 211 along the first direction to the second swirl channel 212. In other words, the orthographic projection of the first filter screen 32 in the first direction overlaps with both the first swirl channel 211 and the second swirl channel 212. The first water passage 31 is connected to the swirl channel 21. Specifically, in some embodiments, a plurality of first through holes 3a (such as Figure 9As shown, the first through hole 3a connects the first water passage 31 with the swirl passage 21. Due to the restriction of the first through hole 3a, the liquid in the swirl passage 21 can flow into the first water passage 31 through the first through hole 3a. However, the solids in the swirl passage 21 cannot pass through the first through hole 3a and are blocked by the first through hole 3a to the space between the first filter 32 and the swirl assembly. In some embodiments, the diameter of the first through hole 3a 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 3a can be set to 0.3 mm. Wherein, the first through hole 3a can be set as a cylindrical hole, and then the diameter of the first through hole 3a represents the diameter of a circle. Of course, the cross-section of the first through hole 3a can also be set to an irregular shape, for example, the cross-section of the first through hole 3a can be set to an elliptical, triangular, or square shape. When the cross-section of the first through hole 3a is set to an irregular shape, the diameter of the first through hole 3a can be represented by the diameter of a standard circle of equal area. In the embodiment of the present invention, 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. It can be regarded as that the first filter almost completely separates the solids and liquid in the fluid.

[0074] like Figure 7 As shown, in the embodiment of the present invention, the first filter screen 32 is extended from the first vortex channel 211 to the second vortex channel 212 along the first direction. The fluid mixed with solids and liquid enters the first vortex channel 211 from the vortex inlet 22, and part of the liquid can pass through the first filter screen 32 located in the first vortex channel 211 and enter the first water passage 31. The remaining fluid can continue to flow into the second vortex channel 212. After the fluid enters the second vortex channel 212, part of the liquid passes through the first filter screen 32 located in the second vortex channel 212 and enters the first water passage 31. 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 23, thereby reducing the risk of solids clogging the first filter screen 32 and improving the fluidity of the liquid in the first water passage. The first filter extends into the first swirl channel, improving fluid filtration efficiency. The first filter extends into the second swirl channel. The extension direction of the first filter within the second swirl channel is inconsistent with the original flow direction of the fluid within the first swirl channel. The filter within the second swirl channel can rectify the fluid flow, significantly weakening the swirl intensity of the liquid entering the first water passage. This significantly reduces the resistance of the entire separator and helps improve the stability of the separator structure. Furthermore, the first filter is longer, which helps improve filtration efficiency.

[0075] In some embodiments, as Figure 7As shown, the first filter assembly 3 further includes an inner cylinder 33. The inner cylinder 33 is hollow and is disposed in the first water passage 31. The inner cylinder 33 is hollow and can be understood as the inner cylinder 33 being open at both ends in the first direction, and the inner cylinder 33 is arranged through in the first direction. The inner cylinder 33 has one end in the first direction ( Figure 7 The left end shown in FIG2 is fixedly connected to the inner wall surface 241 of the swirl volute 24 and communicates with the first water outlet 4. Figure 7 As shown, the inner cylinder 33 has the other end ( Figure 7 The first water outlet 4 can be provided through one end of the swirl volute 24 in the first direction, and the inner cylinder 33 can cover the entire first water outlet 4, so that liquid in the first water outlet 31 can only flow through the interior of the inner cylinder 33 to the first water outlet 4. The embodiment of the present invention, by providing the inner cylinder within the first water outlet, facilitates the rectification of the liquid before it flows out to the first water outlet, thereby improving the consistency of the liquid's movement direction.

[0076] In some embodiments, as Figure 7 As shown, the length L1 of the inner cylinder 33 in the first direction is greater than or equal to 0.2 times the first dimension L2 and less than or equal to 0.5 times the first dimension L2, where the first dimension L2 is the length of the first filter screen 32 in the first direction. In this embodiment of the present invention, by setting the length of the inner cylinder to be greater than a certain value, the inner cylinder can act as a fluid barrier in the gap between the first filter screen and the swirl volute, preventing solids in the first swirl channel from flowing into the first water passage through the gap between the first filter screen and the swirl volute, thereby improving the filtration efficiency of the first filter screen. By setting the length of the inner cylinder to be less than a certain value, the extension of the inner cylinder can reduce interference with the flow of liquid in the first water passage, thereby improving the efficiency of liquid conduction in the first water passage.

[0077] In some embodiments, as Figure 7 As shown, the second swirl channel 212 includes a first sub-cavity 213 and a second sub-cavity 214 separated in the vertical direction. It should be noted that separation means that the first sub-cavity 213 and the second sub-cavity 214 are independent of each other in the vertical direction, but not completely closed. The first sub-cavity 213 and the second sub-cavity 214 can be connected at one end on the first side, for example Figure 7 In the embodiment shown, the first sub-cavity 213 and the second sub-cavity 214 are away from one end of the first swirl channel 211 in the first direction ( Figure 7 The first filter screen 32 is partially located in the first sub-cavity 213, and the first sub-cavity 213 is connected to the first swirl channel 211 and the second sub-cavity 214 at both ends in the first direction, as shown in FIG. Figure 7 As shown, the fluid entering the first swirl channel 211 will continue to flow forward along the first sub-cavity 213 ( Figure 7 The liquid flows to the right (as shown), with part of the liquid entering the first water passage 31. The remaining liquid drives the solids to continue to move into the second sub-chamber 214. The second sub-chamber 214 is provided with a swirl outlet 23, through which the solids and a small amount of liquid can be discharged. In this embodiment of the present invention, by dividing the second swirl channel into a first sub-chamber and a second sub-chamber in the vertical direction, the fluid mixed with solids and liquid enters the second sub-chamber from the first sub-chamber and is then discharged through the swirl outlet. This helps reduce the risk of solids flowing back into the first swirl channel again, and also helps to set the swirl outlet at a lower height, thereby improving the efficiency of fluid discharge.

[0078] In some embodiments, as Figure 7 As shown, the first filter assembly 3 further includes a first drive assembly 34. The first drive assembly 34 is connected to the first filter screen 32 and is configured to drive the first filter screen 32 to rotate in a first direction. It should be noted that the embodiment of the present invention does not limit the frequency or speed of the rotation of the first drive assembly 34, as long as the first drive assembly 34 can drive the first filter screen 32 to rotate. As the liquid in the swirl channel enters the first water passage, solids in the swirl channel are blocked from the first water passage by the first filter screen. Some solids may adhere to the first filter screen due to the influence of the water flow or the size of the first through-hole 3a. In the embodiment of the present invention, the first drive assembly drives the first filter screen to rotate, and the solids on the first filter screen are separated from the surface of the first filter screen due to inertia. This reduces the risk of solids adhering to the first filter screen, improves the water flow efficiency of the first filter screen, and further enables the self-cleaning of the first filter assembly, eliminating the need for cleaning and improving user convenience.

[0079] In some embodiments, combined Figure 7-Figure 9 As shown, the first drive assembly 34 includes a first drive motor 341, a first drive rod 342 and a flow guide 343. Figure 8 As shown, one end of the first drive rod 342 is connected to the first drive motor 341. The first drive rod 342 extends along the first direction. The direction in which the first drive rod 342 extends represents the direction of the maximum size of the first drive rod 342. The first drive motor 341 can drive the first drive rod 342 to rotate around the first direction. It should be noted that the embodiment of the present invention does not limit the specific type of the first drive motor 341. For example, the first drive motor 341 can be a stepping motor or a servo motor, as long as the first drive motor 341 can drive the first drive rod 342 to rotate. Figure 9As shown, the guide member 343 is connected to the other end of the first drive rod 342. It should be noted that the guide member 343 can be fixedly connected to the first drive rod 342. The embodiment of the present invention does not limit the specific connection form of the guide member 343 and the first drive rod 342. For example, the guide member 343 can be permanently connected to the first drive rod 342 by welding or integral molding. For example, the guide member 343 can also be detachably connected to the first drive rod 342 by snap-fitting or other methods, as long as the rotation of the first drive rod 342 can drive the rotation of the guide member 343.

[0080] like Figure 9 As shown, the guide member 343 is arranged in the first water passage 31, wherein, in combination with Figure 7 and Figure 9 As shown, the cross-sectional area of ​​the guide member 343 gradually increases from the end close to the swirl volute 24 to the direction connected to the first drive rod 342. The cross section of the guide member 343 is perpendicular to the first direction. The cross-sectional area can be understood as the area of ​​the cross section of the guide member 343. In some embodiments, the guide member 343 can be configured as a cone. Then, the cross section of the guide member 343 is circular, so it can be used Figure 9 The change of the diameter H of the guide member 343 in the cross section is used to represent the change trend of the cross-sectional area. Figure 9 As shown, the diameter H of the guide member 343 gradually increases from left to right along the first direction. During the rotation of the guide member 343, the liquid in the second vortex channel 212 will flow along the surface of the guide member 343 toward the direction away from the center of the guide member 343 under the stirring of the guide member 343. That is to say, the liquid flows from left to right along the first direction. When the liquid flows close to the guide member 343, the liquid in the first water passage 31 will flow along the surface of the guide member 343 toward the first sub-cavity 213, and the liquid flowing toward the first sub-cavity 213 will drive the solids in the first sub-cavity 213 to flow toward the second sub-cavity 214, which is conducive to the liquid guiding the solids in the first sub-cavity into the second sub-cavity, thereby improving the separation efficiency of the separator.

[0081] In the embodiment of the present invention, the first filter 32 can be fixedly connected to the guide member 343. The embodiment of the present invention does not limit the specific connection method of the first filter 32 and the guide member 343. Figure 9 In the embodiment shown, the bottom surface of the guide member 343 ( Figure 9 The right end surface shown in the figure) can be fixedly connected to the first filter screen 32, and the bottom surface area of ​​the guide member 343 is large, which is conducive to improving the stability of the connection between the first filter screen and the guide member.

[0082] In some embodiments, as Figure 10As shown, the width M of the first vortex channel 211 narrows along the direction of fluid flow. It should be noted that the flow direction of the fluid in the first vortex channel 211 is to enter the first vortex channel 211 from the vortex inlet 22 and then flow in a spiral along the first vortex channel 211. The embodiment of the present invention gradually narrows the width of the first vortex channel, which is beneficial to changing the movement direction of the fluid and causing the fluid to spirally move so that the solids in the fluid generate inertial centrifugal force during the movement; according to the principles of fluid dynamics, as the width of the first vortex channel narrows, the speed of the fluid will increase, which is beneficial to improving the efficiency of the separator filtration.

[0083] In some embodiments, as Figure 1 and Figure 2 As shown, the separator 1 further includes a second filter assembly 5. The second filter assembly 5 is connected to the cyclone outlet 23 of the cyclone channel, and the second filter assembly 5 is used to filter the fluid between the first filter assembly 3 and the cyclone assembly 2. Specifically, in combination Figure 5 and Figure 7 As shown, after the fluid passes through the first filter assembly 3, the fluid discharged from the vortex outlet 23 contains solids and a small amount of liquid. By connecting the vortex outlet 23 with the second filter assembly 5, the second filter assembly 5 can perform secondary filtration on the fluid discharged from the vortex outlet 23 and collect the solids in the fluid discharged from the vortex outlet 23 for centralized discharge, thereby reducing the risk of solids accumulating between the first filter assembly and the vortex housing to affect the filtering efficiency of the first filter assembly. The second filter assembly 5 can again separate the fluid discharged from the vortex outlet 23 into solids and liquid. The separated liquid can be circulated to the dishwasher again, and the separated solids can be discharged in a centralized manner, thereby improving the separation efficiency.

[0084] In some embodiments, as Figure 10 As shown, the second filter assembly 5 includes a cup body 51, a first shell 52, and a second filter screen 53. A water inlet chamber 511 is provided inside the cup body 51. One end of the water inlet chamber 511 is open in the vertical direction. The water inlet chamber 511 is connected to the outside of the separator. When the separator is used in a dishwasher, the water inlet chamber 511 can be used to receive the fluid to be separated in the dishwasher. The fluid can be introduced into the water inlet chamber 511 through the upper end of the cup body 51. Figure 10 The direction of the arrow in the middle represents the direction of movement of the fluid. The water inlet chamber 511 is also connected to the vortex inlet 22, and the fluid entering the water inlet chamber 511 can enter the vortex channel through the vortex inlet 22.

[0085] like Figure 10As shown, the first shell 52 is arranged in the water inlet chamber 511, and the first shell 52 is provided with a water outlet chamber 521 connected to the outside of the separator. The water outlet chamber 521 is isolated from the water inlet chamber 511. Isolation means that the water inlet chamber 511 and the water outlet chamber 521 are not connected to each other. The fluid in the water inlet chamber 511 cannot enter the water outlet chamber 521, and the liquid in the water outlet chamber 521 cannot enter the water inlet chamber 511. The second filter 53 is arranged in the water outlet chamber 521, and the second filter 53 is provided with a receiving chamber 531. Figure 5 As shown, the accommodating chamber 531 connects the vortex outlet 23 and the water outlet chamber 521. The second filter 53 is used to guide the liquid between the first filter assembly 3 and the vortex assembly 2 into the water outlet chamber 521, and to retain solids between the first filter assembly 3 and the vortex assembly 2 within the accommodating chamber 531. The accommodating chamber 531 can collect solids in the fluid, facilitating their centralized discharge. The liquid in the water outlet chamber 521 can be re-introduced into the dishwasher for recycling.

[0086] In some embodiments, as Figure 10 As shown, the swirl inlet 22 is arranged near the bottom of the cup body 51. It should be noted that "close" means that the swirl inlet 22 is closer to the bottom of the cup body 51 in the vertical direction, and the distance can be expressed by the distance between the center of the swirl inlet 22 and the bottom surface of the cup body 51. For example, the distance can be less than or equal to one tenth of the height of the cup body 51, and the height of the cup body 51 is the size of the cup body 51 in the vertical direction. In the embodiment of the present invention, by arranging the swirl inlet 22 near the bottom of the cup body, the liquid level in the water inlet chamber can also be guided into the swirl channel by the swirl inlet at a lower height. In some embodiments, a water pump is provided to improve the efficiency of introducing the fluid from the water inlet chamber into the swirl channel. By arranging the swirl inlet near the bottom of the cup body, the risk of water pump air suction is reduced.

[0087] In some embodiments, as Figure 10 As shown, the second filter 53 extends in the vertical direction. It should be noted that the vertical direction described in the embodiment of the present invention refers to the vertical direction in the absolute coordinate system, and the extension direction of the second filter 53 in normal use is parallel to the vertical direction. The second filter 53 can be set as a structure that is through in the vertical direction, and at least one end of the second filter 53 is open in the vertical direction, such as Figure 10As shown, the lower end of the second filter screen 53 is open and communicates with the swirl outlet 23. Fluid discharged from the swirl outlet 23 can enter the accommodating chamber 531 through the lower end of the second filter screen 53. The upper end of the second filter screen 53 vertically abuts the inner wall surface 522 of the first housing 52. It should be noted that the abutment between the second filter screen 53 and the inner wall surface 522 of the first housing 52 indicates that the second filter screen 53 and the first housing 52 do not have a fixed connection, and the second filter screen 53 and the first housing 52 can be in close contact. This allows the second filter screen 53 to move relative to the first housing 52 without increasing the gap between the second filter screen 53 and the first housing 52, thereby reducing the risk of solids in the accommodating chamber 531 flowing through the gap into the water outlet chamber 521. Furthermore, the second filter screen extends vertically, sharing the solid residue collection function of the first filter assembly, which helps reduce the horizontal dimensions of the first filter assembly and improves the overall compactness of the separator.

[0088] In some embodiments, as Figure 10 As shown, the second filter screen 53 is provided with a plurality of second through holes 5a, the second through holes 5a communicate with the accommodating cavity 531 and the water outlet cavity 521, and the second through holes 5a are connected to the accommodating cavity 531 and the water outlet cavity 521. Figure 5 As shown, the fluid entering the accommodating chamber 531 from the swirl outlet 23 is mixed with a small amount of liquid and solids. Due to the restriction of the second through hole 5a, the solids are flowed into the accommodating chamber 531, and the liquid can pass through the second through hole 5a into the water outlet chamber 521, which can not only filter the fluid, but also collect the solids in the accommodating chamber, which is conducive to the centralized discharge of the solids. In some embodiments, the diameter of the second through hole 5a is greater than or equal to 0.1 mm and less than or equal to 0.4 mm. For example, the diameter of the second through hole 5a can be set to 0.3 mm, wherein the second through hole 5a can be set as a cylindrical hole, then the diameter of the second through hole 5a represents the diameter of a circle. Of course, the cross-section of the second through hole 5a can also be set to an irregular shape, for example, the cross-section of the second through hole 5a can be set to an elliptical or square shape. When the cross-section of the second through hole 5a is set to an irregular shape, the diameter of the second through hole 5a can be represented by the diameter of a standard circle of equal area. By setting the diameter of the second through-hole within a certain range, the embodiment of the present invention can filter out 99% of solids in the fluid. This can be considered as the second filter almost completely separating the solids from the liquid in the fluid. Furthermore, the diameter of the second through-hole in the embodiment of the present invention can be smaller than or equal to the diameter of the first through-hole. In other words, the second through-hole can completely separate the solids from the liquid in the fluid, which helps reduce the risk of secondary contamination of dishware by the recycled water in the dishwasher.

[0089] In some embodiments, as Figure 10As shown, the second filter assembly 5 further includes a second drive assembly 55. The second drive assembly 55 is connected to the second filter screen 53 and is configured to drive the second filter screen 53 to rotate vertically. It should be noted that the present invention does not limit the frequency and speed of the second drive assembly 55, as long as the second drive assembly 55 can drive the second filter screen 53 to rotate. After the liquid in the swirl channel enters the accommodating chamber 531, the solids in the accommodating chamber 531 are blocked by the second filter screen 533. Some of the solids may adhere to the second filter screen due to the influence of the water flow or the size of the second through hole 5a. In the present invention, the second drive assembly drives the second filter screen to rotate. The solids on the second filter screen are separated from the surface of the second filter screen due to inertia, reducing the risk of solids adhering to the second filter screen and facilitating improved water flow efficiency of the second filter screen. Furthermore, the second filter assembly can be self-cleaned, eliminating the need for cleaning and improving user convenience.

[0090] In some embodiments, as Figure 10-12 As shown, the second driving assembly 55 includes a second driving motor 551, a second driving rod 552 and a connecting member 553. One end of the second driving rod 552 ( Figure 12 The second drive rod 552 extends in the vertical direction, and the second drive motor 551 is used to drive the second drive rod 552 to rotate in the vertical direction. The other end of the second drive rod 552 ( Figure 12 The upper end shown) is connected to the connecting member 553, as shown Figure 11 As shown, the connecting member 553 is fixedly connected to the second filter screen 53. The embodiment of the present invention does not limit the specific method of connecting the connecting member 553 to the second filter screen 53, as long as the connecting member 553 can drive the second filter screen 53 to rotate in the vertical direction.

[0091] In some embodiments, combined Figure 11 and Figure 12 As shown, the connecting member 553 includes an annular portion 5531 and a reinforcing rib 5532. The annular portion 5531 is arranged around the vertical direction, and the annular portion 5531 is fixedly connected to the inner wall surface of the second filter screen 53. The reinforcing rib 5532 is arranged along the radial direction of the annular portion 5531, and the reinforcing rib 5532 is fixedly connected to the second drive rod 552. The reinforcing rib 5532 in the embodiment of the present invention can be provided in plurality, one end of each reinforcing rib 5532 is fixedly connected to the annular portion 5531, and the other ends of the plurality of reinforcing ribs 5532 are connected to each other and to the second drive rod 552. By providing the connecting member with a structure of an annular portion and reinforcing ribs, the present invention allows the water in the accommodating chamber to pass through the gap between the reinforcing rib and the annular portion in the vertical direction and to be fixedly connected to the second filter screen. In addition, by providing a plurality of reinforcing ribs, the stability of the connection between the connecting member and the second filter screen can be increased.

[0092] In some embodiments, as Figure 1 As shown, the separator 1 also includes a drainage component 6. Figure 14 and Figure 15 As shown, the drain assembly 6 is internally provided with a drainage channel 61, which connects the water outlet cavity 521 with the exterior of the separator. When the separator 1 is used in a dishwasher, the drainage channel 61 connects the water outlet cavity 521 with the outlet pipe of the dishwasher. The drainage channel 61 is used to guide the liquid in the water outlet cavity 521 into the dishwasher for recycling.

[0093] In some embodiments, as Figure 14 and Figure 15 As shown, the drainage channel 61 is connected to the first water outlet 4. The first water outlet 4 is used to discharge the liquid filtered by the first filter assembly. The drainage channel 61 is connected to the first water outlet 4, so that the liquid discharged from the first water outlet 4 merges with the liquid discharged from the water outlet cavity 521 and is discharged into the dishwasher through the drainage channel 61 for recycling. By providing the drainage channel and connecting the drainage channel to the first water outlet, the embodiment of the present invention can make the structure of the separator more compact, which is conducive to the centralized discharge of the filtered liquid.

[0094] In some embodiments, combined Figure 1 、 Figure 14 and Figure 15 As shown, one end of the drainage channel 61 that is connected to the water outlet chamber 521 is the channel inlet 611, and the channel inlet 611 and the swirl inlet 22 are spaced apart in the vertical direction. It should be noted that the spacing means that the channel inlet 611 and the swirl inlet 22 are not located at the same position in the vertical direction, but are staggered in the vertical direction, and the position of the swirl inlet 22 in the vertical direction is lower than the position of the channel inlet 611. The embodiment of the present invention does not limit the distance between the swirl inlet 22 and the channel inlet 611 in the vertical direction. By spacing the channel inlet and the swirl inlet in the vertical direction, the flow of the fluid between the swirl inlet and the channel inlet does not interfere with each other, which is conducive to improving the fluid diversion efficiency.

[0095] In some embodiments, as Figure 2 and Figure 13 As shown, the second filter assembly 5 further includes a drain channel 56, one end of which communicates with the accommodating chamber 531. A drain outlet 57 is provided at the other end of the drain channel 56, which communicates with the exterior of the separator. Specifically, a drain valve may be provided within the drain channel 56, and the opening state of the drain outlet 57 may be controlled by controlling the drain valve. If the separator 1 is installed in a dishwasher, the drain outlet 57 may communicate with the exterior of the dishwasher to facilitate the discharge of solid residue within the accommodating chamber to the exterior of the dishwasher.

[0096] In some embodiments, as Figure 2 As shown, the sewage outlet 57 is in the vertical direction ( Figure 2 As shown in the up and down direction) close to the first shell ( Figure 2 The bottom of the second filter assembly 5) is shown. Close to the bottom means that the distance between the drain outlet 57 and the bottom of the first shell is less than a set value, and the set value can be 0.9 times the height of the first shell. In the embodiment of the present invention, by setting the drain outlet at a position close to the bottom of the first shell, solids at a lower height in the accommodating chamber are easily discharged from the drain outlet. In some embodiments, a sewage pump can be provided at the drain outlet to extract the solid residue in the accommodating chamber to the outside of the separator by suction. By setting the height of the drain outlet at a lower level, it is beneficial to reduce the extraction of solids in the accommodating chamber and reduce the risk of solids remaining in the accommodating chamber.

[0097] The embodiment of the present invention also provides a cleaning device, such as Figure 16 As shown, the cleaning device can be a dishwasher, a washing machine and other equipment. The embodiment of the present invention is described by taking the cleaning device as a dishwasher as an example. The cleaning device includes a separator 1 and a cleaning shell 7 according to any of the above items. An isolated cleaning chamber 71 and a separation chamber 72 are provided inside the cleaning shell 7. Isolation means that the cleaning chamber 71 and the separation chamber 72 are separated from each other and are not connected to each other. Only a specific pipe can connect the separation chamber 72 and the cleaning chamber 71. The cleaning chamber 71 in the embodiment of the present invention is used to accommodate objects to be cleaned. For example, the cleaning chamber 71 can be used to accommodate tableware such as plates, bowls, and chopsticks. The separator 1 is arranged in the separation chamber 72. The cleaning shell 7 is also provided with an inlet pipe 73 and an outlet pipe 74. The inlet pipe 73 connects the cleaning chamber 71 with the vortex inlet 22 of the separator 1, and the outlet pipe 74 connects the water outlet 11 of the separator 1 with the cleaning chamber 71. It should be noted that, in combination with Figure 7 、 Figure 10 and Figure 14 As shown, in an embodiment in which the separator 1 is provided with a cyclone component 2 and a first filter component 3 and is not provided with a second filter component 5, the outlet pipe 74 can be directly connected to the first water outlet 4; in an embodiment in which the separator 1 is also provided with a second filter component 5, the liquid discharged from the separator 1 is divided into two parts, one part flows out from the first water outlet 4 in the first filter component 3, and the other part is discharged from the second filter component 5 to the drainage channel 61 and then flows out. After the water of the two parts converge, they flow into the outlet pipe 74 from the water outlet 11 of the separator.

[0098] In some embodiments, combined Figure 10 As shown, the inlet pipe 73 can be connected to the water inlet chamber 511 of the second filter assembly 5, combined with Figure 14 As shown, the outlet pipe 74 can be connected to the drainage channel 61 in the drainage assembly 6. The working process of the dishwasher is described below:

[0099] like Figure 16 As shown, the bowls to be washed are placed in the cleaning chamber 71. Clean liquid impacts the surface of the bowls and washes away the residue on the surface of the bowls to form a solid-liquid mixture with residue. In order to improve the cleanliness of the bowls, the bowls need to be rinsed multiple times, so the solid-liquid mixture needs to be separated to form a liquid without residue. The liquid is processed and then circulated to rinse the bowls. Figure 10 As shown, the solid-liquid mixture after rinsing the bowls can be directed into the water inlet chamber 511 through the inlet pipe 73, and then the solid-liquid mixture in the water inlet chamber 511 is introduced into the cyclone channel through the cyclone inlet 22. After being filtered by the first filter component, most of the liquid enters the drainage channel 61 through the first water outlet 4, and the remaining liquid flushes the solids screened out by the first filter component into the second filter component; Figure 14 As shown, the second filter assembly can collect solid residues and introduce the remaining liquid into the water outlet cavity 521. The remaining liquid then flows into the drainage channel 61 through the water outlet cavity 521. The liquid discharged from the water outlet cavity 521 merges with the liquid discharged from the first water outlet 4 and is introduced into the outlet pipe 74 (as shown in FIG. Figure 16 As shown), the water is finally circulated into the cleaning chamber 71 through the outlet pipe 74 for cyclic flushing of the bowls.

[0100] In some embodiments, a water pump is provided in the outlet pipe 74. By providing the water pump, a negative pressure is formed in the outlet pipe 74, and a pressure difference is formed between the outlet pipe 74 and the drainage channel, so that the liquid in the drainage channel can flow quickly into the outlet pipe, so as to improve the efficiency of the circulating liquid diversion.

[0101] In some embodiments, as Figure 16 As shown, the outlet pipe 74 includes a plurality of sub-pipes 741, which are interconnected and spaced apart in the vertical direction of the cleaning chamber 71. Of course, in other embodiments, the plurality of sub-pipes 741 can be spaced apart in other directions of the cleaning chamber 71, and the bowls in the cleaning chamber 71 can be arranged in multiple rows. By providing a plurality of sub-pipes 741, one or more sub-pipes 741 can be arranged opposite to a row of bowls, which facilitates accurate flushing of the bowls and helps improve the cleaning degree of the bowls. Figure 16 As shown, each sub-pipe 741 is provided with a plurality of outlets 742 in the horizontal direction, and the outlet 742 is used to introduce the liquid in the sub-pipe 741 into the surface of the object to be cleaned in the cleaning chamber 71. By providing a plurality of outlets, the area of ​​liquid flushing in the cleaning chamber is facilitated, thereby improving the cleanliness of the dishes in the cleaning chamber.

[0102] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
