Description

Technical Field

[0001] This invention relates to a pump capable of filtering and collecting micro-lint, and also to a washing machine having the above-mentioned pump. Background Technology

[0002] Microfibers are fiber particles with a length of less than 5 mm.

[0003] In 2011, Browne et al. first proposed that household washing of synthetic fiber clothing is an important source of microfibers, and through experiments, they showed that a single wash of a garment can release more than 1,900 fibers, which drew attention to the source of microfibers released by household washing.

[0004] In 2017, the International Union for Conservation of Nature (IUCN) published a research report on primary microfibers released into the global oceans. The report showed that washing synthetic fabrics can release up to 35% of primary microfibers into the ocean.

[0005] The direct release of microfibers can lead to the following problems:

[0006] 1. Microfibers directly affect the physical and chemical properties and material cycling of soil: After entering the soil environment and combining with other organic pollutants, microfibers, due to their small particle size and large specific surface area, have a significantly enhanced adsorption capacity, thereby altering the physical and chemical properties of the soil and affecting the health of the soil ecosystem.

[0007] 2. Microfiber mainly affects soil animals through ingestion: After being ingested by animals, microfiber can cause intestinal damage, easily clump together in the body, affect feeding and excretion, and lead to a significant decrease in survival rate, body length and reproductive capacity.

[0008] 3. Microfibers alter the microbial community and biodiversity of soil ecosystems: The presence of soil microfibers may become a carrier of other toxic and harmful substances. As microfibers migrate, they will affect the microorganisms in the soil, thereby affecting the health of the soil ecosystem.

[0009] With the increase in global consumption of synthetic fiber textiles, the number of washing machines and the frequency of washing, the need to filter and collect the microfibers generated during the washing process has become very urgent.

[0010] In particular, in washing machines, the drainage water generally needs to be discharged through a pump. How to install a filter on the pump so that it can effectively filter and collect lint, especially microfibers, has become an urgent technical problem to be solved.

[0011] In view of this, the present invention is hereby proposed. Summary of the Invention

[0012] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a pump that agitates the water flow within the pump chamber, causing the water flowing through the filter element to become a rotating flow, thereby achieving the purpose of filtering out tiny lint particles in the water flow. Furthermore, another objective of this invention is to provide a filter pump that can be used to attach and collect the filtered and intercepted lint particles.

[0013] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0014] A pump includes: a pump casing, wherein a filter chamber and an impeller chamber are interconnected within the pump casing; a cylindrical filter element disposed within the filter chamber for filtering flowing water; and a stirring element disposed within the cylindrical filter element, wherein the stirring element and / or the cylindrical filter element are connected to an impeller disposed within the impeller chamber and driven by a motor to rotate around an axis, thereby rotating and forming agitated water flow within the filter chamber.

[0015] Furthermore, the filter element is fixedly connected to the pump casing, and the agitator is connected to the impeller in the impeller cavity that is driven by the motor to rotate around the shaft; or, the agitator is fixedly connected to the pump casing, and the filter element is connected to the impeller in the impeller cavity that is driven by the motor to rotate around the shaft; or, both the filter element and the agitator are connected to the impeller in the impeller cavity that is driven by the motor to rotate around the shaft.

[0016] Furthermore, the stirring component includes a rotating rod coaxially arranged with the cylindrical filter element, and the rotating rod is provided with radially protruding wave blades.

[0017] Furthermore, the outer peripheral wall of the rotating rod is provided with radially protruding wave blades arranged along a spiral line.

[0018] Furthermore, the radial width of the wave blade gradually increases from one end of the rotating rod to the other. The end with a larger radial width of the wave blade is away from the impeller cavity, while the end with a smaller radial width is coaxially connected to the impeller in the impeller cavity.

[0019] Furthermore, the agitator is located inside the cylindrical filter element, and the rotating rod of the agitator is coaxially arranged with the cylindrical filter element. The radial width of the radially protruding undulating blades on the outer wall of the rotating rod is smaller than the radius of the cylindrical filter element.

[0020] Furthermore, one end of the rotating rod of the agitator is coaxially connected to the shaft of the impeller in the impeller chamber, and the other end is suspended or connected to a support that can rotate relative to the filter element; preferably, one end of the rotating rod is detachably and synchronously connected to the shaft of the impeller via a quick-release structure, and / or, the other end of the rotating rod is detachably and relatively rotatably connected to the filter element via a quick-release structure.

[0021] Furthermore, the filter chamber is cylindrical; the first end of the cylindrical filter chamber is closed by the pump cover, the second end is connected to the impeller chamber, and the middle of the side wall of the cylindrical filter chamber is connected to the water inlet provided on the pump casing; the pump cover is detachably installed at the installation port of the pump casing; the cylindrical filter element and / or the agitator are coaxially installed in the cylindrical filter chamber.

[0022] Furthermore, the cylindrical filter element is coaxially installed inside the columnar filter chamber. The center of the water inlet end of the cylindrical filter element is provided with an outwardly protruding rotating shaft. The rotating shaft is rotatably connected to the pump cover but cannot move axially relative to it.

[0023] Furthermore, the filter chamber is provided with a ring of annular partition ribs, which together with the inner wall of the columnar filter chamber form an outer chamber, and the inside of the annular partition ribs forms an inner chamber; the annular partition ribs themselves are provided with, and / or there is a water passage gap between the annular partition ribs and the inner wall of the columnar filter chamber, which connects the outer chamber and the inner chamber; the cylindrical filter element and the stirring element are both coaxially arranged in the inner chamber.

[0024] Furthermore, one end of the agitator passes through the cylindrical filter element and engages with the detachable threaded connection of the pump cover.

[0025] This invention discloses a washing machine equipped with a washing machine pump with integrated filtration function as described above.

[0026] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0027] By installing a filter on the pump, foreign objects such as lint in the water flow are trapped, which not only improves the filtration rate, but also avoids the problem of impeller and foreign objects getting tangled and accumulating at the washing machine pump, greatly improving water flow.

[0028] By installing a stirring element that can rotate relative to the filter element in the filter chamber, a stirring water flow can be formed in the filter chamber, so that the water flow passing through the filter screen is a rotating water flow. When the rotating water flow flows through the filter screen, it can be effectively filtered by the filter screen due to rotation, so that tiny fibers smaller than the pore size of the filter screen can still be intercepted by the filter screen, thereby achieving the effect of filtering and collecting microfibers.

[0029] Meanwhile, the water flow in the filter chamber is agitated by the stirring element, which causes the lint trapped by the filter element to aggregate, thus achieving the purpose of collecting the filtered lint. At the same time, by setting the stirring element in the filter chamber, the aggregated lint can be hung on the stirring element, so that the user can clean the stirring element to remove the collected lint, thus achieving a significant technological advancement in the rapid collection and cleaning of lint.

[0030] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0047] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0048] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] like Figures 1 to 15 As shown in the figure, an embodiment of the present invention introduces a washing machine pump, which includes: a pump housing 100, with a chamber inside the pump housing 100; an inlet 101 and an outlet 102 on the pump housing 100, the chamber being connected to the inlet 101 and the outlet 102 to form a water passage; an impeller 400, disposed in the chamber, rotating within the chamber driven by a motor 300 mounted on the pump housing 100, causing the water in the chamber to flow under the driving force provided by the centrifugal force generated by the rotation of the impeller; and a filter element 200, disposed in the chamber, used to filter the flowing water and trap lint in the water. By setting a filter element on the pump, foreign objects such as lint in the water flow are trapped, which not only improves the filtration rate but also avoids the problem of impeller and foreign objects entangled and accumulating at the washing machine pump, greatly improving water flow.

[0050] In this embodiment of the invention, the filter element 200 is disposed upstream of the impeller 400, near the water inlet 101, in the chamber portion to trap foreign objects such as lint upstream of the impeller 400 and prevent them from contacting the impeller 400. Thus, the water flow in the washing machine pump is filtered before flowing into the chamber portion where the impeller is installed, trapping foreign objects such as lint in the water flow into the chamber upstream of the impeller, allowing the filtered water, free of foreign objects, to flow into the impeller mounting chamber.

[0051] In this embodiment of the invention, the pump casing may also be provided with a residual water outlet, which is connected to the lowest point of the chamber inside the pump casing, so as to discharge the residual water in the chamber of the pump casing to the outside, thereby achieving the purpose of inspection and maintenance of the pump.

[0052] like Figures 1 to 15 As shown in the figure, this embodiment introduces a washing machine pump, which includes a pump housing 100, a filter chamber 104 and an impeller chamber 105 that are interconnected inside the pump housing 100; the pump housing 100 is provided with an inlet 101 and an outlet 102, the inlet 101 is connected to the filter chamber 104, the filter chamber 104 is connected to the impeller chamber 105, and the impeller chamber 105 is connected to the outlet 102 to form a water path; the filter chamber 104 is provided with a partition structure to divide the filter chamber 104 into two interconnected parts, forming a zigzag flow channel connecting the inlet 101 and the impeller chamber 104 of the pump housing 100; the filter chamber 104 is provided with a filter element 200 for filtering the lint from the water flowing through the zigzag flow channel.

[0053] The above configuration creates a zigzag flow channel within the pump casing's filter chamber, extending the water path length and increasing the water flow time and velocity within the pump casing. This allows the filter elements within the zigzag flow channel to effectively filter the flowing water, improving the pump's filtration efficiency and enabling more lint to be intercepted and collected by the filter elements.

[0054] like Figure 2 As shown, in this embodiment, the filter chamber 104 is cylindrical; the partition structure includes an annular partition rib 107 disposed inside the cylindrical filter chamber 104, the annular partition rib 107 and the inner wall of the cylindrical filter chamber forming an outer chamber 108, and the interior of the annular partition rib 107 forming an inner chamber 109; the annular partition rib 107 itself is provided with, and / or there is a water passage gap 110 between the annular partition rib 107 and the inner wall of the cylindrical filter chamber 104, the water passage gap 110 connecting the outer chamber 108 and the inner chamber 109. Preferably, the annular partition rib 107 and the cylindrical filter chamber 104 are coaxially arranged so that the filter elements 200 inside the pump housing 100 are evenly distributed, and the flowing water can pass evenly through all parts of the side wall of the filter elements 200, thereby greatly improving the efficiency of water filtration.

[0055] like Figure 2 As shown, in this embodiment, the first end 112 of the columnar filter chamber 104 is closed, and the second end 113 is connected to the impeller chamber 105. The middle part of the side wall of the columnar filter chamber 104 is connected to the water inlet 101. One end of the annular partition rib 107 is connected to the inner circumference of the annular baffle provided at the second end 113 of the columnar filter chamber 104, and the other end maintains a distance from the first end 112 of the columnar filter chamber 104, forming a water passage gap 110, so that the water can pass through naturally. The water flowing into the outer chamber 108 from the inlet 101 flows into the inner chamber 109 of the filter chamber 104 through the water passage 110 described at the first end 112. The water flowing into the inner chamber 109 of the filter chamber 104 from the first end 112 is filtered by the filter element 200 and then flows into the impeller chamber 105 through the second end 113. This achieves a significant technical advancement by forming a zigzag flow channel in the filter chamber 104 of the pump casing 100 and improving the water filtration effect.

[0056] like Figures 1 to 8As shown, in this embodiment, the filter element 200 is cylindrical, extending along the axial direction of the columnar filter cavity 104. The two ends of the cylindrical filter element 200 are the inlet end 203 and the outlet end 204, respectively. An annular gap 111 exists between the sidewall of the cylindrical filter element 200 and the inner wall of the annular partition rib 107. One end of the annular gap 111 is blocked by the baffle rib 114 at the inlet end 203 of the cylindrical filter element 200, and the other end communicates with the gap channel 115 between the outlet end 204 of the cylindrical filter element 200 and the columnar filter cavity 104, and connects to the leaf blade via an opening 116. The impeller cavity 105 is connected so that all the water flowing into the inner chamber 109 from the first end 112 flows into the interior of the cylindrical filter element 200 through the water inlet 203 of the filter element 200. The water inside the cylindrical filter element 200 is filtered by the filter screen 202 on the side wall and then flows into the annular gap 111 between the cylindrical filter element 200 and the annular partition rib 107. It then flows into the impeller cavity 105 through the gap channel 115 and the opening 116 at the second end 113 of the filter cavity 104. This achieves the effect of the water flowing back and forth in the filter cavity 104 and filtering lint.

[0057] like Figures 1 to 8 As shown, in this embodiment, the sidewall of the cylindrical filter element 200 is composed of a ring of filter screens 202 laid on the sidewall of the support 201. The two ends of the support are the inlet end 203 and the outlet end 204, respectively. Preferably, the support at the inlet end is provided with multiple inlets so that the flowing water can flow into the interior of the cylindrical filter element from the inlets. More preferably, the support at the outlet end is also provided with multiple outlets, and the aperture of the outlets is smaller than that of the inlets. Through the above arrangement, the lint in the flowing water can be effectively intercepted inside the filter element, and the problem of excessive lint causing poor water flow can be avoided. In particular, the outlet end of the filter element is provided with an outlet of a certain aperture, which not only ensures that some of the flowing water can be diverted through the outlet end, reducing the water pressure inside the filter element, but also achieves the effect of effectively intercepting and collecting the lint filtered by the filter element.

[0058] In this embodiment, filter 202 is a filter with smaller pores, which further enhances the filter's effect on filtering and intercepting microfibers. The mesh size is 10-300 mesh, preferably 50-200 mesh. The material can be metallic nickel, stainless steel, or polymer materials. Nylon is preferred.

[0059] like Figures 1 to 8As shown, in this embodiment, a removable pump cover 103 is installed on the pump housing 100. The second end 113 of the columnar filter chamber 104 is formed by the pump cover 103, so that after the pump cover 103 is installed, it seals the mounting opening 118 of the chamber inside the pump housing 100. After removing the pump cover 103, the mounting opening 118 of the chamber can be opened, and the interior of the chamber can be cleaned, maintained, and operated. Preferably, the outer periphery of the pump cover 103 is provided with external threads, and the pump housing 100 is provided with a mounting opening 118 with internal threads. The pump cover 103 is detachably installed at the mounting opening 118 through the engagement of the internal and external threads.

[0060] like Figures 1 to 8 As shown, in this embodiment, the filter element 200 is installed on the pump cover 103 and can be removed from the filter chamber 104 along with the disassembled pump cover 103, thereby improving the convenience of pump cleaning and maintenance. Preferably, in this embodiment, the pump cover 103 has a mounting groove 119 at the center of the side facing the inside of the filter chamber 104, and the center of the water inlet end 203 of the cylindrical filter element 200 is provided with an outwardly protruding, coaxially arranged rotating shaft part 206. The rotating shaft part 206 is inserted into the mounting groove and is engaged with the mounting groove 119 by a radially protruding annular rib, so as to realize the installation between the filter element 200 and the pump cover 103, and achieve the effect of the filter element 200 being installed in the filter chamber 104 with a ring gap 111 between it and the annular partition rib 107 in a suspended state. Preferably, in order to ensure the sealing of the connection between the pump cover 103 and the pump housing 100, at least one sealing ring 117 is provided at the connection between the pump cover 103 and the pump housing 100 to prevent water leakage at the connection between the pump cover 103 and the pump housing 100.

[0061] like Figures 2 to 8 As shown, in this embodiment, the outer periphery of the pump cover 103 facing the interior of the pump housing cavity is provided with a ring-shaped mounting rib 121 protruding into the cavity along the axial direction of the columnar filter cavity 104. The ring-shaped mounting rib 121 is connected to the ring-shaped partition rib 107 provided in the mounting cavity 104 of the pump housing 100 and the water inlet end 203 of the filter element 200, so as to separate the inner cavity and the outer cavity. At the same time, multiple water passage holes 120 are provided on the ring-shaped mounting rib 121. Each water passage hole connects the part between the ring-shaped mounting rib 121 and the water inlet end 203 of the filter element, so that the water in the outer cavity 108 can flow into the inner cavity 109 through the water passage holes 120, and then flow into the interior of the filter element 200 through the opening of the water inlet end 203.

[0062] like Figures 1 to 8As shown, in this embodiment, the impeller cavity 105 is disc-shaped, and the axis of the disc-shaped impeller cavity 105 coincides with or is parallel to the axis of the columnar filter cavity 104; the middle part of the disc-shaped impeller cavity 105 is connected to the filter cavity 104 through the opening 116, and the outer peripheral side is connected to the outlet 102; the disc-shaped impeller cavity 105 is provided with a coaxially arranged impeller 400, and a motor 300 is installed on the pump casing 100. The motor 300 drives the impeller 400 to rotate around the centrally arranged rotating shaft 401, which is used to provide a driving force for the water flow in the impeller cavity 105 to flow towards the outer peripheral outlet 102.

[0063] like Figure 3 As shown, in this embodiment, the filter chamber 104 may also be provided with a plurality of self-cleaning particles 600 that can move with the water flow and clean the filter element by moving; preferably, there is an annular gap 111 between the side wall of the columnar filter element 200 and the annular partition rib 107, and the annular gap 111 is filled with a plurality of cleaning particles 600. The diameter of the cleaning particles 600 is smaller than the radial dimension of the annular gap 111, so as to achieve the effect of cleaning the filter screen 202 laid on the side wall of the filter element 200 by the flow of water; further preferably, in order to prevent the cleaning particles 600 from flowing out of the filter chamber 104 with the water flow, a radially outward protruding rib is provided at the water outlet end of the filter element. The gap H between the outer periphery of the protruding rib and the inner wall of the filter chamber is smaller than the diameter d of the cleaning particles 600, so as to prevent the cleaning particles 600 from flowing out of the filter chamber 104.

[0064] Example 1

[0065] like Figures 1 to 8 As shown, in this embodiment, the filter element 200 can be connected to the rotating shaft 401 at the center of the impeller 400, allowing the filter element 200 to rotate around the shaft with the impeller 400. This rotation significantly improves the filtration effect on fine lint, effectively preventing lint from passing through the filter element. Simultaneously, by installing the filter element in the filter chamber so that it rotates with the impeller, a rotating water flow is formed within the filter chamber. This allows foreign objects such as lint trapped by the filter element to move with the water flow, aggregating the lint together. This represents a significant technological advancement in collecting filtered lint and improving the filtration effect of the filter element.

[0066] like Figures 1 to 8 As shown, in this embodiment, the middle part of the impeller cavity 105 is connected to the filter cavity 104, and the outer periphery is connected to the outlet 102. An impeller 400 is installed in the impeller cavity 105, which is coaxially arranged and can be driven by the motor 300 to rotate around the axis. The rotating shaft 401 of the impeller 400 is coaxially connected to the filter element 200, which is used to drive the filter element 200 to rotate together with the impeller 400.

[0067] In this embodiment, the filter element 200 is cylindrical, and the water outlet 204 of the cylindrical filter element 200 is coaxially connected to the rotating shaft 401 of the impeller 400. The cylindrical filter element 200 can be driven by the impeller 400 to rotate coaxially, which reduces the mesh size of the filter screen 202 laid on the side wall of the cylindrical filter element 200. This allows the filter screen to still intercept small debris smaller than the pore size in the water flow, thus achieving a significant technological advancement in effectively intercepting tiny debris in the flowing water.

[0068] In this embodiment, the filter element 200 is detachably connected to the impeller 400 via a quick-release structure. This quick-release structure can be any structure found in the prior art, enabling rapid assembly and disassembly between the filter element 200 and the impeller 400, thereby facilitating quick cleaning and maintenance of the filter element 200 within the pump. A specific example of the quick-release structure is as follows:

[0069] like Figures 1 to 8 As shown, in this embodiment, the quick-release structure includes a quick-connect plug 205 located at the center of the outlet end 204 of the cylindrical filter element 200; and a quick-connect socket 402 located at the end of the rotating shaft 401 of the impeller 400. The quick-connect plug 205 and quick-connect socket 402 each have correspondingly fitted recesses and protrusions that can be inserted together. Preferably, in this embodiment, when the quick-connect plug 205 and quick-connect socket 402 are inserted, the corresponding recesses and protrusions make contact with each other, forming a contact surface. This ensures that the cylindrical filter element and the impeller form a non-rotatable insertion connection, allowing the cylindrical filter element to rotate around the axis with the impeller.

[0070] In this embodiment, the quick-connect plug 205 has multiple axially outward protrusions on its end face, with each protrusion evenly distributed on the outer periphery of the end face of the quick-connect plug 205; the impeller 400's shaft 401 has multiple recesses, each recess corresponding to a protrusion for corresponding insertion and connection. Preferably, in this embodiment, the quick-connect plug 205 and the quick-connect socket 402 each have multiple recesses and protrusions, with each recess and protrusion symmetrically distributed relative to the axis of the cylindrical filter element 200.

[0071] Example 2

[0072] like Figures 1 to 10As shown in the figure, this embodiment introduces a washing machine pump, which includes a pump housing 100, a filter chamber 104 and an impeller chamber 105 that are interconnected inside the pump housing 100; an inlet 101 and an outlet 102 are provided on the pump housing 100, and the filter chamber 104 is connected to the inlet 101, the impeller chamber 105 and the outlet 102 to form a water channel; a filter element 200 is provided in the filter chamber 104 for filtering the flowing water; an agitator 500 is provided in the filter chamber 104, and the agitator 500 is connected to the impeller 400 in the impeller chamber 105 that is driven by a motor 300 to rotate around an axis, so that agitated water flow is formed in the filter chamber 104. When the agitated water flow passes through the filter screen laid on the side wall of the filter element, it performs lint filtration, especially for filtering and collecting microfibers and other tiny lint.

[0073] By installing a stirring element that can rotate relative to the filter element in the filter chamber, a stirring water flow can be formed in the filter chamber, so that the water flow passing through the filter screen is a rotating water flow. When the rotating water flow flows through the filter screen, it can be effectively filtered by the filter screen due to rotation, so that tiny fibers smaller than the pore size of the filter screen can still be intercepted by the filter screen, thereby achieving the effect of filtering and collecting microfibers.

[0074] Meanwhile, the water flow in the filter chamber is agitated by the stirring element, which causes the lint trapped by the filter element to aggregate, thus achieving the purpose of collecting the filtered lint. At the same time, by setting the stirring element in the filter chamber, the aggregated lint can be hung on the stirring element, so that the user can clean the stirring element to remove the collected lint, thus achieving a significant technological advancement in the rapid collection and cleaning of lint.

[0075] In this embodiment, it is possible to, for example Figure 9 As shown, the filter element 200 is fixedly connected to the pump casing 100, and the agitator 500 is connected to the impeller 400 in the impeller cavity 104, which is driven by the motor 300 to rotate around the shaft. This allows the agitator 500 to rotate with the impeller 400 and form a water flow in the filter cavity 104, causing the intercepted wire debris to be hung by the agitator and form a larger clump of wire, thereby achieving the effect of collecting the intercepted wire debris.

[0076] It's alright, such as Figure 10As shown, the agitator 500 is fixedly connected to the pump casing 100, and the filter element 200 is connected to the impeller 400, which is driven by the motor 300 to rotate around its axis, located in the impeller cavity 105. This allows the filter element 200 to rotate with the impeller 400, creating a water flow within the filter cavity 104. The intercepted wire debris is then trapped by the agitator 500 and formed into a larger ball, thus achieving the effect of collecting the intercepted wire debris. At this time, one end of the rotating rod 501 of the agitator 500 is a connecting part 503. The connecting part 503 passes through the water inlet end 203 of the filter element 200 and is connected to the pump cover 103. It can be detachably connected to the pump cover 103 by means of threaded engagement or other methods.

[0077] Alternatively, the filter element 200 and the agitator 500 can both be connected to the impeller 400, which is driven by the motor 300 to rotate around the shaft, so that the filter element 200 and the agitator 500 rotate with the impeller 400 to form a water flow in the filter chamber 104, and the intercepted wire debris is hung by the agitator to form a larger clump of wire, which can also achieve the effect of collecting the intercepted wire debris (not shown in the attached drawings).

[0078] In this embodiment, the description is further elaborated by connecting the agitator 500 and the impeller 400. By adopting the above method, a certain agitated water flow can be formed in the filter chamber 104 when the filter element rotates, which causes the trapped wire debris to aggregate under the action of the agitated water flow. The aggregated wire debris will also be hung on the agitator 500 and collected on the agitator 500. However, this application is not limited to the above solution, and other solutions described in this application can also be adopted.

[0079] In this embodiment, the following example is used for illustration:

[0080] like Figure 10 As shown, in this embodiment, the stirring member 500 includes a rotating rod 501 coaxially arranged with the filter chamber 104. The outer peripheral wall of the rotating rod 501 is provided with radially protruding wave blades 502, so as to enhance the stirring effect of the water flow under the action of the radially protruding wave blades 502, so that the lint is aggregated faster and collected more thoroughly.

[0081] In this embodiment, the outer peripheral wall of the rotating rod 501 is provided with radially protruding wave blades 502 arranged along a spiral line to enhance the intensity and coverage of the stirring water flow. Preferably, the stirring water flow generated by the wave blades 502 arranged along the spiral line is a stirring water flow pushed towards the first end 112 of the filter chamber 104 to guide the lint in the filter chamber 104 to gather towards the first end 112, thereby achieving a significant technological advancement in improving the lint collection effect and facilitating user cleaning of lint.

[0082] In this embodiment, the radial width of the undulating blade 502 gradually increases from one end of the rotating rod 501 to the other end. The end of the undulating blade 502 with a larger radial width is away from the impeller cavity 105, and the end with a smaller radial width is coaxially connected to the impeller 400 in the impeller cavity 105. This allows the agitated water flow generated inside to push the collected wire debris toward one end of the filter cavity 104, so that the wire debris is gathered at the first end 112 of the cylindrical filter cavity 104 with a larger radial width of the undulating blade 502.

[0083] In this embodiment, the agitator 500 is disposed inside the cylindrical filter element 200. The rotating rod 501 of the agitator 500 is coaxially arranged with the cylindrical filter element 200. The radial width of the radially protruding wave blades 502 on the outer wall of the rotating rod 501 is less than or equal to the radius of the cylindrical filter element 200, so as to form agitated water flow inside the cylindrical filter element 200, thereby pushing the lint trapped inside the cylindrical filter element 200 to one end, achieving the effect of collecting foreign objects such as lint trapped in the cylindrical filter element 200.

[0084] In this embodiment, one end of the rotating rod 501 of the agitator 500 is a connecting part 503. The connecting part 503 passes through the water outlet end 204 of the filter element 200 and is coaxially connected to the central rotating shaft 401 of the impeller 400, so that the agitator 500 can rotate synchronously around the shaft with the impeller. Preferably, the connecting part 503 of the rotating rod 501 and the rotating shaft 401 of the impeller 400 are coaxially threaded to achieve the purpose of detachable connection between the agitator 500 and the impeller 400, which can rotate together around the shaft.

[0085] In this embodiment, the other end of the rotating rod 501 is located at the water inlet end 203 of the filter element 200, and it can be suspended at a distance from the filter element 200; it can also be connected to the water inlet end 203 of the filter element 200 in a rotatable support, so as to achieve the effect of the rotating rod being installed inside the filter element and rotating around the axis.

[0086] Example 3

[0087] This embodiment, based on the above embodiments, also has the following technical features:

[0088] like Figures 9 to 15 As shown, this embodiment introduces a pump, which includes,

[0089] Pump casing 100, with a filter chamber 104 and an impeller chamber 105 that are interconnected inside the pump casing 100;

[0090] The pump casing 100 is provided with an inlet 101 and an outlet 102. The filter chamber 104 is connected to the inlet 101, the impeller chamber 105 and the outlet 102 to form a water passage.

[0091] The filter element 200 is disposed in the filter chamber 104 and is used to filter the flowing water, and the filtered water flows to the impeller chamber 105.

[0092] The collection chamber 106 is connected to the filter chamber 104 and is used to collect the lint filtered by the filter element 200.

[0093] This application utilizes a separate collection chamber on the pump casing to collect microfibers and other debris trapped by the filter element, effectively preventing the debris from moving with the water flow within the pump body and failing to be thoroughly cleaned. In particular, this application incorporates a detachable agitator inside the filter element, allowing it to rotate with the impeller after installation. This agitator pushes the trapped microfibers into the collection chamber through the agitated water flow, achieving a significant technological advancement in cleaning the filter element and collecting the trapped microfibers.

[0094] In this embodiment, the collecting cavity 106 is open at one end facing the filtering cavity 104 and is connected to the filtering cavity 104, and the opposite end has a mounting port 118. A detachable pump cover 103 corresponding to the closed mounting port is installed at the mounting port 118. Preferably, the external thread of the pump cover 103 on its outer periphery is threadedly engaged with the internal thread on the hole wall of the mounting port 118. More preferably, at least one sealing ring is provided at the point where the pump cover 103 and the pump housing 100 can be connected.

[0095] In this embodiment, the collection chamber 106 is provided with a drawer section 122, the interior of which forms an upward-opening lint collection groove. The pull-out end of the drawer section 122 is connected to the pump cover 103, and the extension end is located at the connection between the collection chamber 106 and the filter chamber 104. The extension end of the drawer section 122 is provided with multiple through holes 125 that connect the lint collection groove and the filter chamber 104. By providing the drawer section, microfibers and other materials entering the collection chamber can be retained in the drawer section, thereby allowing the user to remove the drawer section and the collected microfibers simply by removing the pump cover, simplifying the user's operation.

[0096] In this embodiment, there is a certain gap between the opening 126 of the drawer portion 122 and the top wall of the collection chamber 106, and the top opening 126 of the drawer portion 122 is lower than the highest point of the filter chamber 104. The lint collection groove inside the drawer portion 122 is connected to the filter chamber 104 through the top opening 126.

[0097] like Figure 9 and Figures 12 to 15As shown, in this embodiment, the filter chamber 104 is cylindrical, and its two ends are connected to the impeller chamber 105 and the collection chamber 106, respectively. An inlet 101 is provided on the side wall of the cylindrical filter chamber 104. A cylindrical filter element 200 is coaxially arranged inside the annular partition 107 of the cylindrical filter chamber 104. The end of the cylindrical filter element 200 connected to the filter chamber and the collection chamber 104 is the inlet end 203, and the inlet end 203 is provided with multiple inlet holes 207. The end of the cylindrical filter element 200 connected to the filter chamber 104 and the impeller chamber 105 is the outlet end 204, and the outlet end 204 is covered with a filter screen 202. The side walls of the cylindrical filter element 200 are all composed of filter screens 202.

[0098] In this embodiment, filter 202 is a filter with smaller pores, which further enhances the filter's effect on filtering and intercepting microfibers. The mesh size is 10-300 mesh, preferably 50-200 mesh. The material can be metallic nickel, stainless steel, or polymer materials. Nylon is preferred.

[0099] In this embodiment, the cylindrical filter element 200 includes a support 201 and a filter screen 202. The water inlet end 203 of the cylindrical filter element 200 is rotatably mounted on the mounting member 123 via a central rotating shaft. The mounting member 123 is a cover plate structure covering the connection between the filter chamber 104 and the collection chamber 106. The mounting member 123 is detachably mounted at the connection between the filter chamber 104 and the collection chamber 106. Multiple water passage holes 120 are arranged on the outer periphery of the mounting member 123. The outer chamber 108 is connected to the interior of the cylindrical filter element 200 through the water passage holes 120 and the water inlet hole 207 of the water inlet end 203 of the cylindrical filter element 200.

[0100] In this embodiment, the mounting component 123 is provided with a plurality of auxiliary through holes 124 that are opened opposite to the through holes 125 provided on the drawer portion 122; each through hole 125 and each auxiliary through hole 124 are at least partially staggered so that the through holes 125 and the auxiliary through holes 124 can together form a microfiber extrusion channel for microfibers to be squeezed through by pressure, so that microfibers and other filaments in the filter chamber 104 can be squeezed into the microfiber extrusion channel and enter the collection chamber 106 under the pushing pressure provided by the stirring water flow in the filter chamber 104.

[0101] In this embodiment, the through hole 125 and the auxiliary through hole 124 are located in the middle region of the cylindrical filter chamber 104, and the water inlet hole 207 of the water inlet end 203 of the cylindrical filter screen 202 is also located in the middle region, at least partially opposite to the through hole 125, so as to facilitate the flow of microfibers and other lint collected inside the cylindrical filter element 200 into the collection chamber 106. Preferably, a plurality of water inlet holes 207 are arranged at intervals around the central axis at the water inlet end 203 of the cylindrical filter element 200.

[0102] In this embodiment, in order to achieve isolation between the filter chamber and the collection chamber, at least one sealing ring 117 can be provided on the outer periphery of the mounting member 123 in contact with the inner wall of the pump housing 100, so as to achieve the effect of the mounting member isolating the collection chamber from the filter chamber.

[0103] In this embodiment, a detachable agitator 500 is installed inside the cylindrical filter element 200. The agitator 500 is detachably connected to an impeller 400, which is driven by a motor 300 to rotate around its axis, located in the impeller cavity 105. The agitator 500 rotates under the drive of the impeller 400, creating a turbulent water flow within the cylindrical filter element 200. This turbulence pushes the microfibers trapped by the filter element 200 into the collection cavity 106 through the microfiber extrusion channel. The agitator 500 in this embodiment can adopt the structure described in the previous embodiments, which will not be repeated here. Furthermore, the connection structure between the agitator 500 and the impeller 400 can be as follows: Figure 13 The threaded connection shown can also be Figure 14 The quick-connect plug and quick-plug socket shown can be used for any other existing connection method, etc.

[0104] In this embodiment, a pressure sensor (not shown in the drawings) is provided at the outlet 102 of the pump casing 100 to detect the water pressure at the outlet 102. When the water pressure at the outlet exceeds the set range, a warning signal is issued to remind the user to clean the filter. After receiving the warning signal, the user disassembles and installs the agitator inside the cylindrical filter and connects it to the impeller. Then, the impeller is driven by the motor to rotate, forming a stirring water flow in the filter chamber. The stirring water flow cleans and aggregates the lint trapped on the filter screen and pushes it into the collection chamber. Finally, the user only needs to disassemble and reassemble the pump cover to remove the agitator and clean the lint collected in the drawer.

[0105] With the above settings, the pump does not require an agitator during normal use; it can filter lint from the flowing water using only the cylindrical filter element. As the usage time increases and the filter screen of the agitator reduces its permeability, the user only needs to remove the pump cover and install the agitator to enable the pump to automatically clean and collect the lint trapped inside the filter element.

[0106] Furthermore, in this embodiment, it is also possible to, for example... Figures 10 to 12 As shown, the stirring element 500 is connected to the impeller 400, and the filter element 200 is connected to the mounting element 123. By rotating the filter element, the same effect of cleaning the lint on the filter screen and pushing it into the collection chamber can be achieved by forming a stirring water flow in the filter chamber.

[0107] Meanwhile, in this embodiment, in order to further facilitate the disassembly of the filter element and the assembly of the agitator, the mounting part and the drawer can be detachably connected by threaded engagement, so that after the pump cover is removed, the drawer, the mounting part and the agitator or filter element installed on it can be directly pulled out together.

[0108] Example 4

[0109] This embodiment also describes a washing machine equipped with any of the washing machine pumps described in the above embodiments.

[0110] In this embodiment, the washing machine pump can be used for washing machine drainage. The inlet 101 of the washing machine pump is connected to the drain outlet of the washing machine's water tank, and the outlet 102 of the washing machine pump is connected to the washing machine's drain pipe. This allows the washing machine pump to filter lint from the washing machine's drainage water, achieving the effect of lint filtration.

[0111] In this embodiment, the washing machine pump can also be used for external circulating water in the washing machine. The inlet 101 of the washing machine pump is connected to the outlet at the bottom of the washing machine's water tank, and the outlet 102 of the washing machine pump is connected to the inlet at the top of the water tank via an external circulation pipe, so as to form a circulating water flow between the washing machine's water tank and the external circulation pipe. The washing machine pump is used to filter lint from the circulating water flow, thereby achieving the effect of lint filtration in the washing water.

[0112] At the same time, whether the above-mentioned washing machine pump is used for drainage filtration or external circulation water filtration of the washing machine, it can use the rotatable filter element installed in the pump to filter and intercept tiny fibers and lint in the water flowing through it, and the intercepted tiny lint will be aggregated and collected by the action of the rotating filter element.
