Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and in particular, relates to a wire scrap collecting device, washing equipment and a control method. Background Art

[0002] In a washing machine for washing clothes, for example, a washing machine, friction between clothes and between clothes and the washing machine itself may cause lint to fall off the clothes and mix into the washing water. When the washing machine is drained after washing, the lint that falls off the clothes will be discharged along with the drainage water.

[0003] However, the concept of microplastics proposed in recent years has gradually received increasing attention in the field of environmental protection. Studies have found that an important source of microplastics is the wastewater discharged from household washing machines. This is because with the popularization of chemical fiber fabrics, clothing fibers that fall off during the washing process are discharged with the washing machine drainage water and become microplastics mixed into the natural water environment. Microplastics enter the ecological cycle directly with the drainage water, and will eventually accumulate in the human body through the natural food chain, which may have an impact on human health. For this reason, some regions have formulated relevant standards for the content of microplastics in washing machine drainage.

[0004] For this reason, it is necessary to filter the drainage of the washing machine before discharging it. However, the microplastics described above are very small in size. In order to effectively filter the microplastics, the filter holes in the device used to filter the drainage of the washing machine also need to be set to a smaller size. However, in this case, if there are too many wire scraps in the drainage water flow, the filter holes will soon be blocked, causing the water flow to be unable to pass through the filter device smoothly, affecting the drainage efficiency. In particular, if the filter holes are blocked during the washing program of the washing machine, the washing machine will not be able to drain smoothly, thereby affecting the continued operation of the washing program.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a lint collection device, a washing device and a control method, which can peel off the attached lint by squeezing the internal flexible filter net, thereby improving the water permeability efficiency of the lint collection device without disassembly.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A wire scrap collecting device, comprising:

[0009] a housing on which a water inlet is disposed;

[0010] A flexible filter screen is arranged inside the housing, the water inlet is connected to the inside of the flexible filter screen, and the wire scraps are collected inside the flexible filter screen;

[0011] The extrusion component is used to squeeze the flexible filter screen to deform it and compress the wire scraps collected inside the flexible filter screen.

[0012] Furthermore, the extrusion assembly comprises:

[0013] A push plate is reciprocatably disposed inside the housing, and the push plate reciprocates to squeeze / release the flexible filter net located on one side of the push plate;

[0014] The driving mechanism is used to drive the push plate to reciprocate inside the shell.

[0015] Further, the housing has a first side wall and a second side wall which are arranged oppositely and in parallel, and the push plate is arranged parallel to the first side wall and reciprocates between the first side wall and the second side wall;

[0016] The flexible filter net is arranged between the push plate and the second side wall; in an initial state, the push plate is in contact with the first side wall, and the flexible filter net is stretched out between the push plate and the second side wall; the push plate moves toward the second side wall, pressing the flexible filter net between the push plate and the second side wall.

[0017] Furthermore, the water inlet is arranged on the second side wall of the shell.

[0018] Furthermore, a water outlet is also arranged on the second side wall, and the water flow filtered by the flexible filter screen is discharged from the water outlet.

[0019] Furthermore, the water inlet and the water outlet are arranged on one of the diagonals of the second side wall and close to two ends of the diagonal.

[0020] Furthermore, the driving mechanism comprises:

[0021] A motor, arranged outside the first side wall;

[0022] The connecting rod is extended along the reciprocating motion direction of the push plate, one end of which is transmission-connected to the motor, and the other end of which passes through the first side wall and is connected to the push plate.

[0023] Furthermore, the unfolded area of ​​the flexible filter net is greater than or equal to 5 times the total area of ​​the inner surface of the shell.

[0024] A washing device comprises the above-mentioned lint collecting device, wherein the water inlet of the lint collecting device is connected to the drainage pipeline of the washing device.

[0025] A control method for the washing device described above, wherein the washing device performs a drainage operation, the squeezing component maintains an initial state, and the flexible filter net remains expanded; after the drainage operation is completed, the squeezing component is controlled to squeeze the flexible filter net.

[0026] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0027] In the present invention, a deformable flexible filter net is used to collect lint in the water flow, and an extrusion component that can squeeze the flexible filter net is provided. After the flexible filter net is squeezed, the lint collected inside it will be compressed into a ball, so that the lint that partially blocks the filter holes can be peeled off from the flexible filter net, releasing some of the filter holes, thereby effectively improving the water permeability efficiency of the flexible filter net.

[0028] In the present invention, a push plate capable of reciprocating movement is provided to squeeze the flexible filter screen, and the push plate can cooperate with the second side wall of the housing to press the flexible filter screen tightly, which has a simple structure and a good stripping effect on the wire scraps. The water inlet communicated with the inside of the flexible filter screen is provided on the second side wall, and during the squeezing of the flexible filter screen, the part thereof communicating with the water inlet does not move substantially, thereby ensuring the stability of the conductive structure between the flexible filter screen and the water inlet.

[0029] In the present invention, thanks to the flexible structure of the flexible filter net, the expanded area of ​​the flexible filter net is much larger than the total area of ​​the inner surface of the housing, and the flexible filter net can still be completely installed inside the housing, and by increasing the expanded area of ​​the flexible filter net, more filter holes for water permeation can be provided. The increase in the number of filter holes can reduce the probability of the filter holes being completely blocked, thereby improving the water permeability of the flexible filter net.

[0041] Embodiment 1

[0042] like Figures 1 to 4 As shown, this embodiment provides a lint collecting device and a washing device having the lint collecting device. The washing device may be a washing machine, a washer-dryer, a care machine, or other washing device having a clothes washing function.

[0043] The lint collection device provided in this embodiment can filter water flow carrying lint and other filtering impurities and collect lint in the water. Specifically, the lint collection device includes a housing 100 and a flexible filter net 200 disposed inside the housing 100. The flexible filter net 200 is a net bag structure, and a filter cavity is formed inside the housing 100 to receive the water flow to be filtered.

[0044] The housing 100 is provided with a water inlet 101 for receiving water to be filtered. The water inlet 101 is connected to the interior of the flexible filter 200, that is, the filter cavity, and water flows directly into the interior of the flexible filter 200 through the water inlet 101. The flexible filter 200 has a plurality of filter holes, through which water can flow to the outside of the flexible filter 200, while the lint in the water is intercepted and collected inside the flexible filter 200.

[0045] The housing 100 is also provided with a water outlet 102, and the water flow after filtering and removing the lint can be discharged from the housing 100 through the water outlet 102. In this way, the lint collecting device can continuously receive the water flow to be filtered, filter out the lint and then discharge it, and collect the lint in the water in the flexible filter net 200.

[0046] In the washing device provided in this embodiment, the water inlet 101 of the lint collection device is connected to the drainage pipeline of the washing device, and the water outlet 102 on the housing 100 is connected to the pipeline to discharge the filtered water. Specifically, the water inlet 101 is connected to a water inlet pipe, and the inlet end of the water inlet pipe is connected to the drainage pipeline of the washing device.

[0047] As a specific embodiment, the lint collection device is built into the washing device. Specifically, the drainage pipeline of the washing device at least includes a first drainage pipe connected to the water storage drum and a second drainage pipe with a water outlet located outside the washing device, and the lint collection device is arranged between the first drainage pipe and the second drainage pipe.

[0048] As another specific embodiment, the lint collection device is externally placed on the washing device. Specifically, the drainage pipeline of the washing device extends to the outside of the washing device, and the water outlet end of the drainage pipeline located outside the washing device is directly connected to the inlet end of the water inlet pipe, and then connected to the water inlet 101 of the lint collection device through the water inlet pipe. The water outlet 102 of the lint collection device is then used for drainage through an additional pipeline. For example, the pipeline connected to the water outlet 102 can be directly connected to the floor drain in the user's home. The arrangement of the lint collection device externally placed on the washing device allows the lint collection device of this embodiment to be applied to existing washing equipment, and users do not need to purchase new washing equipment in order to use the drainage and filtering function of the washing equipment.

[0049] During the operation of the washing equipment, the drainage water flows into the lint collection device for filtration and then is discharged outwards, which can intercept filtered impurities including lint and microplastics from the water, effectively avoiding the problem of excessive microplastic content in the drainage of the washing equipment.

[0050] However, in order to effectively intercept microplastics in the drainage of washing equipment, the filter holes on the flexible filter 200 are very small and easily clogged by wire scraps, resulting in water flow being unable to pass through. When most of the filter holes are clogged by wire scraps, the speed of water flow through the flexible filter 200 will be greatly reduced, affecting the water permeability of the flexible filter 200.

[0051] To solve the above problem, the lint collecting device of this embodiment further comprises a pressing assembly, which can press the flexible filter net 200 to deform it, thereby compressing the lint collected inside the flexible filter net 200 .

[0052] By squeezing the flexible filter 200, the wire scraps inside the flexible filter 200 can be compressed into a ball, and then some of the wire scraps attached to the flexible filter 200 can be peeled off, so that the filter holes on the flexible filter 200 are no longer blocked. After the flexible filter 200 is squeezed, some of the blocked filter holes are released and reopened, which can effectively improve the water permeability of the flexible filter 200. At the same time, during the squeezing of the flexible filter 200, the volume inside the flexible filter 200 is gradually reduced, which can also speed up the efficiency of the water inside the flexible filter 200 being discharged through the blocked filter holes.

[0053] In a further solution of this embodiment, the extrusion assembly includes a push plate 310 and a driving mechanism. The push plate 310 is reciprocatingly disposed inside the housing 100, and the driving mechanism is used to drive the push plate 310 to reciprocate inside the housing 100. The flexible filter 200 is located on one side of the push plate 310, and the reciprocating motion of the push plate 310 can squeeze and release the flexible filter 200, so that the wire scraps attached inside are peeled off.

[0054] Specifically, in this embodiment, the shell 100 of the lint collecting device has a first side wall 111 and a second side wall 112 that are arranged oppositely and in parallel. The push plate 310 is arranged parallel to the first side wall 111 and can reciprocate between the first side wall 111 and the second side wall 112. The flexible filter 200 is arranged between the push plate 310 and the second side wall 112.

[0055] like Figure 2As shown, in the initial state, the push plate 310 is in contact with the inner side of the first side wall 111, so that the flexible filter 200 can be stretched between the push plate 310 and the second side wall 112, thereby forming a filter cavity with a certain volume inside the flexible filter 200. The push plate 310 moves toward the second side wall 112, as shown in FIG. Figure 4 As shown, the flexible filter net 200 can be pressed between the push plate 310 and the second side wall 112, so that the wire scraps collected in the filter cavity are compressed into a ball.

[0056] It should be noted that, in this embodiment, the initial state refers to the state in which the lint collecting device is waiting to receive the water flow to be filtered.

[0057] When the push plate 310 moves to the extreme position in the direction of the second side wall 112, it moves in the opposite direction until it returns to the initial state where the push plate 310 is attached to the first side wall 111. At this time, the push plate 310 is separated from the second side wall 112, and a space is reserved between the two for the flexible filter 200 to be expanded again.

[0058] As a specific implementation, after the push plate 310 is separated from the second side wall 112 to release the flexible filter 200, the flexible filter 200 itself remains piled on the second side wall 112. When water flows into the flexible filter 200 through the water inlet 101 again, the flexible filter 200 can be expanded again under the impact of the water flow and gradually fill the space between the push plate 310 and the second side wall 112.

[0059] As another specific embodiment, the material of the flexible filter 200 has a certain elasticity and can be deformed when squeezed, and after the squeezing force is released, the flexible filter 200 can gradually recover under its own elasticity. It is understandable that the flexible filter 200 can be able to recover to a state of being fully expanded and filling the space between the push plate 310 and the second side wall 112 under its own elasticity, or it can partially recover by its own elasticity, and then completely recover to its original state by the impact force of the water flow when water enters again.

[0060] Furthermore, the water inlet 101 is disposed on the second side wall 112 of the housing 100. When the flexible filter 200 is squeezed and deformed by the push plate 310, the portion thereof communicating with the water inlet 101 will not move substantially, thereby ensuring that the conductive structure between the flexible filter 200 and the water inlet 101 is stable.

[0061] Specifically, the water inlet 101 is in the shape of a sleeve extending outward from the outer wall of the housing 100, so as to facilitate the connection of a pipeline for conveying the water flow to be filtered. The flexible filter screen 200 is provided with an opening for water to enter the interior, and the water inlet connector 210 is sealed and connected to the opening. When the flexible filter screen 200 is installed inside the housing 100, the water inlet connector 210 is sealed and inserted into the water inlet 101 from the inner side of the housing 100, so that the water flow entering from the water inlet 101 can directly enter the interior of the flexible filter screen 200, and will not directly flow into the space between the housing 100 and the flexible filter screen 200 without being filtered.

[0062] Since the water inlet 101 is arranged on the second side wall 112, when the push plate 310 moves to squeeze the flexible filter net 200, the water inlet connector 210 will not be directly squeezed, and the sealing plug-in structure between the water inlet connector 210 and the water inlet 101 will not be damaged, thereby ensuring the filtering effect of the lint collection device on the water flow.

[0063] Furthermore, the water outlet 102 is also disposed on the second side wall 112 of the housing 100. Thus, when the push plate 310 moves toward the second side wall 112 to squeeze the flexible filter 200, the remaining water in the housing 100 can be pushed to flow toward the side where the water outlet 102 is located, thereby ensuring that the water in the housing 100 is fully discharged.

[0064] Specifically, the structure of the water outlet 102 is similar to that of the water inlet 101 , and is also in the shape of a sleeve extending outward from the outer wall of the housing 100 , so as to facilitate connection with a pipe for draining water outward.

[0065] In the preferred solution of this embodiment, the water inlet 101 and the water outlet 102 are arranged on one of the diagonals of the second side wall 112, and close to the two ends of the diagonal. Specifically, the water inlet 101 is arranged at one end of the diagonal close to the top wall of the housing 100, and the water outlet 102 is arranged at one end of the same diagonal close to the bottom wall of the housing 100.

[0066] With the above solution, on the one hand, the water outlet 102 is arranged close to the lowest position of the housing 100, which reduces the possibility of water residue inside the housing 100. On the other hand, the distance between the water inlet 101 and the water outlet 102 is as far as possible, and the water needs to flow through a longer distance in order to flow out from the water outlet 102, thereby making fuller use of the area of ​​the flexible filter net 200, and avoiding the problem that the water flow flows through a local area of ​​the flexible filter net 200 in a concentrated manner, which quickly causes the filter holes in the area to be blocked.

[0067] Furthermore, the housing 100 is formed by an upper housing 121 and a lower housing 122 that are buckled together. The water inlet 101 is arranged on the upper housing 121, and the water outlet 102 is arranged on the lower housing 122. The flexible filter 200 is detachably installed in the housing 100. When the collected lint reaches a certain amount, and the water permeability efficiency cannot be significantly improved even by squeezing the flexible filter 200, the user can remove the upper housing 121, and then remove the flexible filter 200, and then replace it with a new flexible filter 200. After the flexible filter 200 is replaced, the upper housing 121 and the lower housing 122 are buckled again, and the lint collection device can continue to be used.

[0068] In a further solution of this embodiment, in order to realize the driving mechanism driving the push plate 310 to reciprocate, the driving mechanism at least includes a motor 330 and a connecting rod 321. The motor 330 is arranged outside the first side wall 111 and connected to one end of the connecting rod 321 (i.e. Figures 1 to 4 The connecting rod 321 is extended along the reciprocating motion direction of the push plate 310, and its other end (i.e. Figures 1 to 4 The left end in the middle) passes through the first side wall 111 and is connected to the push plate 310.

[0069] The operation of the motor 330 can drive the connecting rod 321 and one end thereof in transmission connection to reciprocate, thereby driving the push plate 310 to reciprocate inside the housing 100 , thereby squeezing or releasing the flexible filter 200 .

[0070] Specifically, the output shaft of the motor 330 is connected to the cam 323, and the operation of the motor 330 can drive the cam 323 to rotate. The cam 323 is provided with a cylindrical transmission part 324 protruding upward, and the transmission part 324 is eccentrically arranged relative to the rotation center of the cam 323. The right end of the connecting rod 321 is provided with a connecting part 322, and the connecting part 322 has a through hole penetrating from top to bottom, and the transmission part 324 is inserted into the through hole, and has a certain movable space in the through hole.

[0071] When the motor 330 is started, its output shaft always rotates in the same direction, which can drive the cam 323 to rotate continuously, so that the transmission part 324 moves along a circular trajectory, and then the linear distance between the transmission part 324 and the first side wall 111 changes continuously. In this way, the motor 330 continuously runs, and the transmission part 324 can drive the connecting part 322 to move back and forth toward and away from the first side wall 111, thereby driving the push plate 310 to reciprocate in the housing 100.

[0072] When the transmission part 324 moves along the circular trajectory to the position farthest from the first side wall 111, the push plate 310 is in the initial position of being in contact with the first side wall 111. When the transmission part 324 moves along the circular trajectory to the position closest to the first side wall 111, the push plate 310 is in the position of completely compressing the flexible filter screen 200, that is, the extreme position close to the second side wall 112.

[0073] In a further solution of this embodiment, in order to prevent water leakage from occurring at the position where the connecting rod 321 passes through the first side wall 111 , a dynamic sealing structure is provided between the outer periphery of the push plate 310 and the inner wall of the housing 100 .

[0074] Specifically, a dynamic seal can be mounted on the outer periphery of the push plate 310, the inner side of the dynamic seal is in sealing contact with the outer periphery of the push plate 310, and the outer side of the dynamic seal is in dynamic sealing contact with the top wall, bottom wall, front side wall and rear side wall of the housing 100. Through the above structure, water entering the lint collecting device can only exist on the left side of the push plate 310, that is, the side where the flexible filter screen 200 is located, while the right side of the push plate 310 is always kept free of water.

[0075] In this way, the first side wall 111 disposed on the right side of the push plate 310 will not come into contact with the water entering the lint collecting device, thereby effectively preventing the problem of water leakage at the position where the connecting rod 321 passes through the first side wall 111.

[0076] On the other hand, in this embodiment, the water outlet 102 on the shell 100 is set on the second side wall 112 located on the left side of the push plate 310, which avoids the problem that the push plate 310 moves over the water outlet 102 to squeeze the flexible filter net 200, resulting in the residual water in the shell 100 cannot be discharged.

[0077] In a further solution of this embodiment, a one-way valve is provided at the water inlet 101, which conducts one-way from the outside to the inside of the housing 100. In this way, it is possible to prevent water from flowing out of the housing 100 of the lint collecting device through the water inlet 101, causing the water carrying a large amount of lint to flow back into the water drum of the washing device, thereby contaminating the clothes.

[0078] Specifically, when the push plate 310 moves to squeeze the flexible filter 200, the residual water in the housing 100 will also be pushed by the push plate 310. As the space between the push plate 310 and the second side wall 112 gradually decreases, the residual water inside the flexible filter 200 and between the flexible filter 200 and the housing 100 will be squeezed to the water inlet 101. By providing a one-way valve at the water inlet 101, the problem of the lint collected in the flexible filter 200 being squeezed out of the water inlet 101 along with the water flow when the push plate 310 moves the flexible filter 200 is effectively prevented.

[0079] This embodiment also provides a control method for the washing device described above, comprising:

[0080] The washing device performs a drainage operation, and the squeezing assembly maintains an initial state, so that the flexible filter screen 200 remains open;

[0081] After the drainage operation is completed, the squeezing assembly is controlled to squeeze the flexible filter net 200 .

[0082] Specifically, during the drainage operation of the washing machine, the push plate 310 is in the initial position of being attached to the first side wall 111, and sufficient space for the flexible filter 200 to be fully opened is reserved between the push plate 310 and the second side wall 112. After the current drainage operation is completed, the control motor 330 is started to drive the push plate 310 to move leftward to squeeze the flexible filter 200, thereby releasing some of the filter holes blocked by the wire scraps.

[0083] After the push plate 310 moves to the left to the limit position, the motor 330 continues to operate, or continues to operate after pausing for a period of time, so as to drive the push plate 310 to return to the right until the push plate 310 is restored to the initial state of being in contact with the first side wall 111 .

[0084] Afterwards, when the washing machine performs the drainage operation again, the flexible filter net 200 can continue to filter the water flow without the problem that most of the filter holes are blocked by wire scraps, resulting in a serious decrease in water permeability efficiency.

[0085] In this embodiment, the washing machine will perform several drainage operations during the washing process. Specifically, after the washing stage is completed and after each rinsing, water will be drained out. After each drainage operation of the washing machine, the push plate 310 is controlled to move to squeeze the flexible filter 200, thereby compressing the accumulated wire scraps during this drainage operation into a ball and releasing the blocked filter holes. When the washing machine performs the drainage operation next time, the filter holes will not be blocked, resulting in the problem of failure to drain water smoothly.

[0086] The lint collection device provided in this embodiment can be used in washing equipment to filter the drainage of the washing equipment, effectively solving the problem that the lint is discharged along with the drainage water flow, resulting in excessive microplastic content in the drainage of the washing equipment. The lint collection device is provided with an extrusion component, which can peel off the attached lint by squeezing the flexible filter net 200, thereby releasing the filter holes blocked by the lint, and ensuring the water permeability of the flexible filter net 200. In this way, the frequency of users disassembling and cleaning the lint collection device is reduced, making it more convenient to use. At the same time, since the flexible filter net 200 can be squeezed during the operation of the washing equipment, the clogging failure of the lint collection device can be solved to a certain extent, and the lint collection device can be prevented from being blocked during the operation of the washing equipment, resulting in the forced interruption of the washing program, thereby improving the user experience.

[0087] Embodiment 2

[0088] like Figures 1 to 4 As shown, this embodiment is a further limitation of the above-mentioned embodiment 1, and the unfolded area of ​​the flexible filter net 200 is much larger than the total inner surface area of ​​the housing 100 .

[0089] Specifically, in this embodiment, the unfolded area of ​​the flexible filter 200 is greater than or equal to 5 times the total area of ​​the inner surface of the housing 100. The unfolded area of ​​the flexible filter 200 specifically refers to the flat area when the flexible filter 200 is fully unfolded. After research and testing, it is found that when the unfolded area of ​​the flexible filter 200 and the total area of ​​the inner surface of the housing 100 have the above-mentioned proportional relationship, the flexible filter 200 can still maintain sufficient water permeability after multiple washing programs are run, avoiding the trouble of users having to frequently replace the flexible filter 200.

[0090] In this embodiment, since the flexible filter 200 has a flexible structure and can be deformed at will, unlike a hard filter, the flexible filter 200 can have an expanded area greater than or equal to the total area of ​​the inner surface of the housing 100, while not affecting the flexible filter 200 from being fully installed inside the housing 100. By increasing the expanded area of ​​the flexible filter 200, it is equivalent to increasing the water-permeable area on the flexible filter 200, and more filter holes for water permeability can be provided on the flexible filter 200. Furthermore, as the number of filter holes increases, the amount of wire scraps required to block all the filter holes is also greater, which can effectively reduce the probability of all the filter holes being blocked, thereby improving the wire scraps collection capacity and water permeability of the flexible filter 200.

[0091] Embodiment 3

[0092] like Figures 1 to 4 As shown, this embodiment is a further limitation of the above-mentioned embodiment one or two, a flow detection device, such as a flow meter, is provided at the water outlet 102, and the washing equipment controls whether the extrusion assembly is actuated according to the detection result of the flow detection device.

[0093] Specifically, in this embodiment, during the washing machine's drainage operation, the flow detection device detects the water flow through the water outlet 102. When the detected water flow is lower than a threshold, the washing machine stops draining and controls the squeezing assembly to squeeze the flexible filter 200.

[0094] More specifically, after the washing machine stops draining, the control motor 330 is started to drive the push plate 310 to move leftward to squeeze the flexible filter 200. After the push plate 310 moves leftward to the limit position, the push plate 310 is driven by the motor 330 to reset rightward until the push plate 310 is restored to the initial state of being attached to the first side wall 111. Then, the washing machine can continue to perform the drainage operation.

[0095] During the drainage of the washing machine, the drainage water flow continues to enter the flexible filter 200. If the flexible filter 200 can filter the water flow normally, the water filtered out of the lint should continue to be discharged from the water outlet 102. Therefore, under normal circumstances, the flow detection device should be able to detect a certain water flow during the drainage of the washing machine. Once most of the filter holes on the flexible filter 200 are blocked by lint, the speed of water passing through the flexible filter 200 will be greatly slowed down, thereby significantly reducing the water flow out of the water outlet 102.

[0096] In the above scheme of this embodiment, the water flow at the water outlet 102 is detected by the flow detection device, and then the squeezing component is controlled to squeeze the flexible filter 200. Once the flexible filter 200 is blocked, the blockage problem can be solved in time. After the squeezing is completed, the squeezing component releases the flexible filter 200, and the washing device can continue to drain water, ensuring the drainage efficiency of the washing device.

[0097] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
