Description

Technical Field

[0001] This utility model relates to the field of filtration and collection equipment, specifically to the field of clothing cleaning technology, and particularly to a filtration and collection device and a washing machine. Background Technology

[0002] Current washing machines primarily assess their ability to remove sweat and dirt during the washing process. However, during washing, clothes accumulate lint, fibers, and particulate contaminants. These contaminants, along with undissolved chemical cleaning agent particles, adhere to the washing machine's tripod, lifting ribs, drying channel, and drum walls. Consequently, the cleanliness of clothes after washing is poor, requiring secondary cleaning. This leads to a significant accumulation of dirt, bacteria, and secondary contamination in washing machines over long-term use.

[0003] Therefore, it is necessary to include a structure in washing machines to collect and filter lint, fabric fibers, particulate contaminants, and undissolved chemical cleaning agent particles. However, existing designs and applications have the following problems regarding the above issues: 1. Collection and filtration device in drum washing machines: Currently, drum washing machines on the market basically do not have the function of filtering and collecting lint, lint, fabric lint, and particulate pollutants.

[0004] 2. A very small number of drum washing machines involve a filter collection device, but this requires a system that converts the detergent particles into foam before the washing process to avoid detergent collection. However, after the detergent particles are converted into foam, most of them float on top of the clothes, making it difficult to achieve optimal cleaning power. Drum washing machines use less water to achieve good tumbling power during the washing process. However, because drum washing machines use less water, there is a problem that clothes are not rinsed clean during the rinsing process. A large amount of foam is generated. Although it avoids the collection of detergent particles, it makes the problem of incomplete rinsing of foam on clothes more serious. Excessive foam makes the inner drum wall and lifting ribs smoother, which reduces the lifting ribs' ability to lift clothes, further reducing the tumbling power. At the same time, the smooth inner drum wall reduces the contact friction between the clothes and the inner drum wall, weakening the cleaning power. Because the system that converts the added detergent particles into foam and the filter and collection device for lint, lint, fabric lint, and particulate pollutants are too large overall, and there is insufficient space between the outer drum and the shell of the pulsator washing machine, they cannot be installed in the pulsator washing machine. As a result, the pulsator washing machine still uses the early filter collection box structure to collect lint, lint, fabric lint, and particulate pollutants.

[0005] 3. The water inlet of the filter collection device developed by the inventor in the early stage was located in the area between the inner drum and the outer drum of the washing machine. Due to market competition, the washing capacity of the inner drum has been increasing and the space between the inner and outer drums of the washing machine has become narrow, which has limited the size of the water inlet of the filter collection device and thus compressed the water flow. Although it meets the application, the more efficient filtration capacity is limited when the user chooses a quick wash. The design structure of this invention requires the user to clean the filter collection device after a certain period of use. Furthermore, the filtration and collection device developed by the inventors in the early stage could only achieve the function of filtration and collection when the inner drum rotated, allowing fluid to enter the filtration and collection device from the inlet. However, since the inner drum rotates reciprocally, it is in an intermittent state each time the rotation direction changes, and the collection and filtration function cannot be achieved at this time. As a result, the filtration and collection does not make full use of the washing time.

[0006] 4. During the washing process, laundry detergent is more effective at cleaning clothes than liquid detergent, and most users wash with cold water. Therefore, when users add laundry detergent granules into the washing machine through the water inlet, they are not completely dissolved. Furthermore, they tend to clump together when exposed to cold water. This causes the existing filtration and collection structure to accumulate, pile up, and clog more quickly when dealing with lint, yarn, fabric debris, and other contaminant particles after washing. Consequently, the filtration and collection efficiency declines rapidly, ultimately failing to provide a good user experience. Crucially, the large amount of undissolved laundry detergent particles collected during the washing process dilutes the detergent, reducing its ability to clean sweat stains and dirt from clothes.

[0007] The following derivative problems exist with existing front-loading and top-loading washing machines used by users: 1. Washing time is long. Users find that the cleaning effect is not ideal during the washing process. The simplest way is to extend the washing time. As a result, users have reported that the washing time of drum washing is longer than that of pulsator washing, which also causes inconvenience to users' life and work. 2. The wear and tear on clothing depends on the duration of cleaning, which leads to excessive soaking, washing, and rinsing of clothes with chemical detergents, resulting in excessive wear and tear and reducing the value of the laundry care process. 3. Long-term use of washing and rinsing equipment causes unnecessary mechanical and physical wear and tear on the equipment and electrical control system, reducing the service life of the equipment and increasing the cost of replacement parts and maintenance. 4. Water and electricity consumption: In order to achieve the goal of cleanliness, users use delayed washing and repeatedly rinse with stored water to clean clothes, which leads to an increase in water and electricity consumption in the long run and a waste of natural resources. 5. Excessive use of chemical detergents or higher prices for detergent brands not only damages clothing due to excessive chemical application, but also reduces rinsing and cleaning effectiveness due to excessive chemical residue. This repeatedly increases the cost of using chemical detergents and increases pollution of social water resources and the environment. 6. Accumulation of Dirt and Glue: Due to the inefficient filtration capacity of top-loading washing machines and the lack of a filtration structure in front-loading washing machines, the uneven and irregular structure between the inner and outer drums, such as the impeller, tripod, lifting ribs, inner drum grille, and collection box base, prolongs the time for lint and contaminants to adhere. Therefore, washing machines that have been used for many years are severely contaminated when disassembled and cleaned. 7. The growth of bacteria not only makes it easy for pollutants to adhere to the surface and cause contamination during the second washing process, but also generates a large number of bacteria, thus providing a favorable and unfavorable environment for the rapid spread of bacteria in public places such as hospitals, hotels, schools, dormitories, community laundromats, and coin-operated laundromats. 8. Increased consumables: Top-loading washing machines have poor collection capabilities, while front-loading washing machines have no collection at all. Long-term use leads to serious accumulation of dirt and bacteria inside the washing machine. Obviously, washing machines used for many years pose a serious health risk to children, women, and the elderly. Users start to buy various chemical cleaners, cleaning brushes, and disassembly tools for cleaning the washing machine drum. However, because the cleanliness of the drum is unclear and the cleaning capacity and energy efficiency cannot be tested, frequent cleaning results in significant financial expenditure for users and chemical pollution of water resources. DIY disassembly and cleaning requires users to spend a lot of time and manpower, and improper disassembly and installation may cause damage to the equipment. 9. Even when the cleaning equipment is in good working order and does not need to be replaced, the inner and outer drums of the washing machine accumulate a large amount of dirt and grime, leading to secondary pollution problems during the washing process. Furthermore, bacterial growth poses unpredictable health risks, forcing users to pay for on-site disassembly and cleaning services. The key issue is that comprehensive on-site disassembly and cleaning methods fail to achieve real-time cleaning and health protection for users.

[0008] Existing collection and filtration devices, due to the unidirectional flow of fluid, are more prone to clogging of the filter screen by lint, fuzz, textile lint, and particulate pollutants collected by the device. After the equipment has finished operating, it cannot achieve self-cleaning of the filter screen.

[0009] The drawbacks of existing filter collection structures: 1. Static adhesion makes it difficult to clean existing filter collection structures. During filtration and collection, the fluid carries the collected material to statically adhere to the filter screen surface in the chamber. As the fluid always passes through the filter screen in a directional manner, the adhesion between the collected material and the filter screen intensifies, making it difficult to clean thoroughly when the fluid is discharged. This leads to filter screen blockage. Furthermore, during equipment operation intervals, the collected material condenses on the filter screen, making it even more difficult for the collected material to self-clean. Over time, this results in cumulative filter screen blockage and eventually the failure of the filtration and collection function. 2. Obstruction of discharge and residue: When the existing filter collection structure is used to discharge and clean the collected materials, there is a problem that the discharged materials are not smooth and remain in the filter collection chamber, which leads to the formation of filter screen blockage. When the equipment is not working, the collected materials will condense on the filter screen, making it even more difficult to clean later. This will lead to the accumulation of blockage and eventually the failure of the filter collection function. 3. Lack of Impact Force and Residual Dirt: In existing filter collection structures, when fluid enters the filter collection chamber to clean the collected material, the flow rate is weak, resulting in insufficient impact force on the inner surface of the filter screen to achieve a cleaning effect. This leads to the accumulation of contaminants on the filter screen surface within the chamber, causing filter clogging. Furthermore, when the equipment is not in operation and the filter collection chamber is not wetted by fluid, the collected material adheres even more firmly to the filter screen surface, further hindering the self-cleaning process. Long-term use leads to cumulative clogging and functional failure. 4. Collecting and diluting chemical particles: Firstly, laundry detergent has a stronger chemical cleaning ability than liquid detergent, and most users wash with cold water. When laundry detergent granules are added to the washing machine drum, they do not dissolve quickly and tend to clump together with cold water. Therefore, in the incompletely dissolved state, during the filtration and collection process, due to the directional collection of fluids and the accumulation of collected materials, the incompletely dissolved laundry detergent particles are also collected into the aggregated lint, fuzz, and fabric fibers. This results in the dilution of the user's laundry detergent during the filtration and collection process, reducing the effectiveness of cleaning sweat stains and dirt on clothes. At the same time, if other chemical cleaning agents are added, such as those used to clean the dirt and grime trapped in the inner drum, the dirt and grime will be removed and collected during filtration and collection, thus achieving the simultaneous filtration and collection of dirt and grime and chemical cleaning agents. 5. Accumulated Filtration Due to the accumulation and clogging of lint, fuzz, textile lint, and particulate matter in the directional filtration system, the filtration efficiency gradually decreases. As the filter becomes increasingly clogged, the pump, which is designed to drive the fluid flow rate, experiences overload. Consequently, the pump power configuration needs to be adjusted based on the flow rate generated by the clogged filter, resulting in under-configured collection power and poor filtration efficiency. 6. Inability to Increase Filter Mesh Size: Users increasingly demand cleaner washing machines to remove lint, fuzz, and particulate matter after washing, and are concerned about the health effects of dirt and bacteria buildup inside the washing machine. Increasing filter density significantly improves filtration efficiency, but current fluid-directed filtration systems still cannot solve the problem of clogging, and achieving thorough automatic cleaning and drainage is even more difficult. Therefore, some users with limited budgets can only add a dryer to further remove lint and fuzz during the drying stage. However, this is obviously more cumbersome and costly, and the washing process still fails to effectively address dirt accumulation, bacterial growth, secondary pollution, and health concerns.

When fluid flows into the filter collection chamber through the middle filter structure or the end filter structure, the one-way opening door on the middle filter structure or the end filter structure separates from the flow hole on the mounting bracket, and the one-way opening door is in the open state. When fluid flows out of the filter collection chamber through the middle or end filter structure, the one-way opening door on the middle or end filter structure blocks the flow hole on the mounting bracket, and the one-way opening door is in the closed state.

The connector body and the end cap are fixedly connected by screws. A connecting post is fixedly provided on one end of the filter element body near the connector body.

[0018] Alternatively, preferably, it also includes a discharge channel, which is connected to the filter collection chamber, and a discharge pump is provided on the discharge channel.

[0019] A washing machine includes a washing machine shell and an outer drum, an inner drum is disposed inside the outer drum, a drain pipe is connected to the outer drum, and a filter collection device is fixedly disposed in the area between the washing machine shell and the outer drum. The ends of the first channel and the second channel away from the filter collection chamber extend into the outer drum and are connected to the inner area of ​​the outer drum. The end of the discharge channel away from the filter collection chamber is connected to the drain pipe.

[0020] Preferably, two filter collection devices are provided, and the two filter collection devices are symmetrically arranged about the vertical plane of the inner cylinder rotation axis, and the discharge channels on the two filter collection devices are interconnected and connected to the drain pipe. The mesh counts of the filter screens on two different filtration and collection devices may be the same or different.

[0021] A method for cleaning clothes, using the aforementioned washing machine, the method comprising the following steps: During the clothes cleaning process, the fluid drive device is activated, driving water to flow from the first channel into the first chamber within the outer drum area of ​​the washing machine. The water then passes through the filter collection structure on the first inlet into the filter collection chamber, and after passing through the filter collection structure on the second inlet, it flows out through the second channel. During this process, the fluid impact causes the filter collection structure on the first inlet to open, allowing the fluid to flow directly into the filter collection chamber from the first channel. After passing through the filter collection chamber, the fluid flows out through the filter collection structure on the second inlet, which is now closed. The fluid impact further ensures the tightness of the closure of the filter collection structure on the second inlet, ensuring that the fluid can only flow out after passing through the filter collection structure on the second inlet. This allows the filter collection structure on the second inlet to filter and collect impurities mixed in the fluid, which are then retained within the filter collection chamber. After running for a period of time, the fluid drive device drives the fluid to change direction. The fluid enters the filter collection chamber from the second channel through the filter collection structure on the second port, and then flows out from the first channel after passing through the filter collection structure on the first port. During this process, under the action of fluid impact, the filter collection structure on the second port is in the open state, and the fluid flows directly into the filter collection chamber from the second channel. After passing through the filter collection chamber, the fluid flows out from the filter collection structure on the first port. At this time, the filter collection structure on the first port is in the closed state. Under the action of fluid impact force, the tightness of the closure of the filter collection structure on the first port is further ensured, so that the fluid can only flow out after passing through the filter collection structure on the first port. Thus, the filter collection structure on the first port is used to filter and collect the impurities mixed in the fluid, and the impurities are retained in the filter collection chamber. This process is repeated until all impurities in the fluid are filtered and collected. When the collected debris needs to be discharged, the solenoid valve and discharge pump on the discharge channel are opened, and the water flowing into the filter collection chamber, along with the collected debris, is discharged from the discharge channel to the drain pipe, and finally discharged through the drain pipe.

[0022] This invention features a simple structure and is easy to use. It uses a fluid drive device to drive fluid to flow alternately through the first and second ports of the bidirectional filtration and collection device. The two filtration and collection structures work together to dynamically move impurities in the fluid within the filtration and collection chamber, thus preventing impurities from adhering to the filtration and collection structure. This avoids clogging the filtration and collection structure, ensuring that the efficiency does not decrease during the impurity filtration and collection process. It also allows for the improvement of collection and filtration efficiency by setting a higher-power fluid drive device.

[0023] This invention utilizes the reversal of the driving fluid to create fluidity in the filter collection chamber. Unlike traditional filter collection devices where pollutants are statically attached, this invention addresses the drawback of static attachment in existing technologies, which easily leads to clogging and a continuous decline in filtration efficiency.

[0024] This invention allows fluid to flow alternately through the first and second passages in the filtration and collection chamber after passing through a filter screen. This ensures that lint, fuzz, fibrous material, and particulate matter carried by the fluid in the filtration and collection chamber remain dynamic within the filtration and collection area, no longer adhering to the filter screen. This causes the lint, fuzz, fibrous material, and particulate matter to tumble, gather, and adhere to the lint, fuzz, fibrous material, and particulate matter on the filter screen within the filtration and collection chamber, thus cleaning the filter screen, ensuring smoother flow, and maintaining the effective collection process.

[0025] This invention not only enables the collection and filtration of lint, fibers, and particulate matter, eliminating the need for secondary lint removal after washing, but also solves the problem of pet hair being difficult to remove from clothes. It also reduces the accumulation of dirt and grime between the inner and outer drums of the washing machine, effectively reducing bacterial growth.

[0026] This invention, when filtering and collecting lint, fuzz, woven lint, and particulate matter, causes these materials to tumble, adhere to, and aggregate. During the discharge process, this facilitates the removal of lint, fuzz, woven lint, and particulate matter, reducing the likelihood of residue buildup on the filter screen and preventing clogging.

[0027] In this invention, the fluid flows alternately in the filter collection chamber, causing undissolved detergent particles to continuously flow within the chamber. This ensures that the detergent particles constantly contact and impact the filter screen, promoting rapid dissolution. The dissolved detergent particles are then circulated back into the washing machine for cleaning clothes, efficiently dissolving and effectively removing sweat and dirt from clothing, thus improving the washing machine's washing ratio.

[0028] This utility model's bidirectional filtration and collection device is detachably connected to the housing, enabling convenient and quick maintenance and replacement of the filter screen.

[0029] In this invention, when collecting and filtering debris, the fluid flushes the filter screen on the first or second through port, ensuring that the filter screen is not clogged. When discharging the collected debris, the fluid also flushes the filter screen on the first and second through ports, further ensuring that the filter screen is not clogged, avoiding manual cleaning of the filter screen, and reducing user operation procedures.

Detailed Implementation

[0046] The present invention will be described below with reference to the accompanying drawings.

[0047] See Figures 1-4 As shown, the present invention provides a filtration and collection device, including a filtration and collection component 24, a first channel 20, and a second channel 21. The filtration and collection component 24 includes a housing 1 and a bidirectional filtration and collection device disposed within the housing 1. The bidirectional filtration and collection device includes a filter element; The filter element is provided with a filter collection chamber 9 and a first chamber. The filter collection chamber 9 is provided with a first through port 14 and a second through port. Both the first through port 14 and the second through port are provided with filter collection structures. The first chamber is connected to the filter collection chamber 9 through the first through port 14. When fluid flows into the filter collection chamber 9 through the filter collection structure, the filter collection structure is in the open state; When the fluid flows out of the filter collection chamber 9 through the filter collection structure, the filter collection structure is in a closed state; The first channel 20 is connected to the first chamber, and the second channel 21 is connected to the filter collection chamber 9 through the second through-port. The first channel 20 and / or the second channel 21 are provided with a fluid driving device for driving fluid flow. The fluid driving device can be a water pump 12.

[0048] In use, the water pump 12 drives the water flow through the first channel 20 into the filter collection element 24, and then discharges through the second channel 21. The filter collection element 24 is used to filter and collect impurities in the water flow. When the impurities are collected to a certain extent and need to be discharged, the discharge pump 23 and the discharge channel 22 are used to discharge the impurities. Alternatively, the filter element can be detachably connected to the housing 1, and the collected impurities can be cleaned by removing the filter element.

[0049] In one embodiment, a second chamber is provided inside the housing 1, and the second chamber is connected to the filter collection chamber 9 through a second through-hole; The second channel 21 is connected to the second passage through the second chamber.

[0050] In one embodiment, see Figures 6-9 As shown, the filter element includes a hollow filter element body 3, a filter collection structure set on the first passage 14 is a middle filter structure 4, and a filter collection structure set on the second passage is an end filter structure 5. The middle filter structure 4 is located in the middle of the filter core body 3, the end filter structure 5 is located at one end of the filter core body 3, and the other end of the filter core body 3 is sealed. The internal area of ​​the filter core body 3 between the end filter structure 5 and the middle filter structure 4 is the filter collection chamber 9.

[0051] See Figures 6-7 As shown, both the middle filter structure 4 and the end filter structure 5 include an annular base 16 and an opening and closing valve plate, and a through hole 15 is provided at the center of the annular base 16. A filter screen 17 is provided on the opening and closing valve plate; The opening and closing valve plate is matched with the annular base 16, and one end of the opening and closing valve plate is rotatably connected to the annular base 16. When fluid impacts the valve plate, the valve plate rotates, blocking the through hole 15 on the annular base 16 or separating from one end of the annular base 16 and opening the through hole 15.

[0052] See Figures 8-9 As shown, both the middle filter structure 4 and the end filter structure 5 include a mounting frame 19, on which a one-way opening door 18 and a filter screen 17 are provided. The mounting bracket 19 is provided with a flow hole for fluid passage at the position corresponding to the one-way opening door 18. The end of the one-way opening door 18 away from the filter screen 17 is rotatably connected to the mounting bracket 19, and the one-way opening door 18 is matched with the flow hole. When fluid flows into the filter collection chamber 9 through the middle filter structure 4 or the end filter structure 5, the one-way opening door 18 on the middle filter structure 4 or the end filter structure 5 separates from the flow hole on the mounting bracket 19, and the one-way opening door 18 is in the open state. When the fluid flows out of the filter collection chamber 9 through the middle filter structure 4 or the end filter structure 5, the one-way opening door 18 on the middle filter structure 4 or the end filter structure 5 blocks the flow hole on the mounting bracket 19, and the one-way opening door 18 is in the closed state.

[0053] In one embodiment, the one-way opening door 18 on the middle filter structure 4 or the end filter structure 5 is located above the filter screen 17 on the respective middle filter structure 4 or the end filter structure 5.

[0054] The filter screens 17 on the middle filter structure 4 and the end filter structure 5 are inclined towards the interior area of ​​the filter collection chamber 9 at the end near the one-way opening door 18 on the mounting bracket 19. This allows collected debris or lint to be deposited on the vertically downward side of the housing 1 during use, which facilitates more thorough removal of debris or lint. See [link to relevant documentation]. Figure 12 The filter collection element 24 in the structure.

[0055] In one embodiment, the bidirectional filter collection device is detachably connected to the housing 1, thereby enabling more convenient cleaning of collected debris or lint.

[0056] A connecting seat 2 is provided on one end of the filter element body that is sealed, and an external thread is provided on the circumferential surface of the connecting seat 2; The housing 1 is provided with a connection hole 6 at one end near the first chamber. The connection hole 6 is provided with an internal thread. The filter element body 3 passes through the connection hole 6 and extends into the internal area of ​​the housing 1. The connecting seat 2 is fixedly connected to the housing 1 by the internal thread and the external thread. The connecting seat 2 includes a connecting seat body 11 and an end cap 10. The connecting seat body 11 and the end cap 10 are fixedly connected by screws. A connecting post is fixedly provided on one end of the filter element body 3 near the connecting seat body 11. The connecting post passes through a matching through hole on the connecting seat body 11 and is axially fixed to the connecting seat body 11 by a snap ring, ensuring that the filter element body 3 does not rotate during the rotation of the connecting seat 2. The through hole is a countersunk hole facing downward towards the filter element body 3, and the outer diameter of the snap ring is larger than the diameter of the through hole.

[0057] In one embodiment, to ensure that the fluid entering the filter collection chamber 9 is free of other excessively large debris, a debris trap 25 is provided on the first channel 20 and / or the second channel 21. The debris trap 25 is a prior art debris trap 25, widely used in drum washing machines. Its structure can be configured as follows: it includes a hollow cylindrical cleaning body, which is connected to the channel to be connected. One end of the hollow cylindrical cleaning body is open, and an internal thread is provided on the open end. A matching screw plug is connected through the internal thread, and a filter baffle is provided on the screw plug, thereby changing the flow direction of the fluid passing through the hollow cylindrical cleaning body. This prevents some larger debris, such as coins, from flowing through the hollow cylindrical cleaning body, thus keeping them inside the hollow cylindrical cleaning body. By rotating the screw plug, the debris can be removed.

[0058] In one embodiment, the system further includes a discharge channel 22, which is connected to the filter collection chamber 9. The discharge channel 22 is equipped with a discharge pump 23, and the housing 1 is equipped with a discharge port 13. The discharge channel 22 is connected to the filter collection chamber 9 through the discharge port 13.

[0059] See Figures 10-15 As shown, a washing machine includes a washing machine housing 26 and an outer drum 27. An inner drum is disposed inside the outer drum 27. A drain pipe is connected to the outer drum 27. A filter collection device is fixedly disposed in the area between the washing machine housing 26 and the outer drum 27. The ends of the first channel 20 and the second channel 21 away from the filter collection chamber 9 extend into the outer drum 27 and are connected to the internal area of ​​the outer drum 27. The end of the discharge channel 22 away from the filter collection chamber 9 is connected to the drain pipe, and the housing 1 can be horizontally arranged inside the washing machine housing 26.

[0060] In one embodiment, two filter collection devices are provided, and the two filter collection devices are symmetrically arranged about the vertical plane of the inner cylinder rotation axis, and the discharge channels 22 on the two filter collection devices are interconnected and connected to the drain pipe. The mesh count of the filter screen 17 on two different filter collection devices may be the same or different.

[0061] In one embodiment, in order to better control the fluid, solenoid valves are provided on the first channel 20, the second channel 21 and the discharge channel 22, and the solenoid valves are opened or closed as needed.

[0062] A method for cleaning clothes, using a washing machine, the method comprising the following steps: During the clothes cleaning process, the fluid drive device is activated, opening the solenoid valves on the first channel 20 and the second channel 21, driving the water flow from the first channel 20 into the first chamber within the inner area of ​​the outer drum 27 of the washing machine. Then, it passes through the middle filter structure 4 and enters the filter collection chamber 9. After passing through the end filter structure 5, it flows out through the second channel 21. During this process, under the action of fluid impact, the middle filter structure 4 is in the open state, and the fluid flows directly from the first channel 20 into the filter collection chamber 9. After the fluid flows through the filter collection chamber 9, it flows out from the end filter structure 5. At this time, the end filter structure 5 is in the closed state. Under the action of fluid impact, the tightness of the end filter structure 5 is further ensured, so that the fluid can only flow out after passing through the end filter structure 5. Thus, the end filter structure 5 is used to filter and collect the impurities mixed in the fluid, and the impurities are retained in the filter collection chamber 9. After running for a period of time, the fluid drive device drives the fluid to change direction. The fluid flows into the second chamber from the second channel 21, then enters the filter collection chamber 9 through the end filter structure 5, flows through the middle filter structure 4 and flows out through the first channel 20. During this process, under the action of fluid impact, the end filter structure 5 is in the open state, and the fluid flows directly into the filter collection chamber 9 from the second channel 21. After the fluid flows through the filter collection chamber 9, it flows out from the middle filter structure 4. At this time, the middle filter structure 4 is in the closed state. Under the action of fluid impact force, the tightness of the closure of the middle filter structure 4 is further ensured, so that the fluid can only flow out after passing through the middle filter structure 4. Thus, the middle filter structure 4 is used to filter and collect the impurities mixed in the fluid, and the impurities are retained in the filter collection chamber 9. This process is repeated repeatedly, ultimately achieving the filtration and collection of impurities in the fluid. This facilitates the flow of collected impurities within the filter screen 17, making it easier for impurities to accumulate. The accumulated impurities then contaminate newly collected impurities on the filter screen 17, cleaning it and further preventing clogging. The filter screen 17 ensures continuous and efficient collection, while also promoting the dissolution of particulate cleaning agents such as laundry detergent.

[0063] When the collected debris needs to be discharged, the solenoid valve on the discharge channel 22 and the discharge pump 23 are opened, and the water flowing into the filter collection chamber 9 is connected with the collected debris and discharged from the discharge channel to the drain pipe, and finally discharged through the drain pipe.
