Description

Technical Field

[0001] This utility model relates to the field of filtration and collection technology, specifically to a filter collection component, a filter collection system, 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, fuzz, textile 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.

[0010] To address the aforementioned problems, this invention provides a filter collection component, a filter collection system, and a washing machine that can filter and collect impurities in fluids, prevent impurities from clogging the filter device, and maintain efficient filtration and collection effects.

[0018] Preferably, the housing is also provided with a fluid outlet, which is connected to the collection area, and a sealing structure is provided between the fluid outlet and the filter device.

[0019] Preferably, the filter device is connected to the housing via a quick-release structure.

[0020] Preferably, the end of the filter device away from the quick-release structure is connected to the housing.

[0021] Preferably, the agitator is located at one end of the housing and is situated inside the filter device. A sealing ring is provided between the filter device and the end of the housing furthest from the quick-release structure.

[0022] Preferably, a check valve is provided at the fluid outlet.

[0023] A filtration and collection system includes the aforementioned filtration and collection component, wherein an inlet pipe is connected to the fluid inlet, a return pipe is connected to the fluid return outlet, and a discharge pipe is connected to the fluid outlet. Both the return pipe and the discharge pipe are equipped with a drive device to drive the fluid flow.

[0024] A washing machine includes a washing machine shell and an outer drum. A drain pipe is connected to the outer drum. A filter collection system is provided in the area between the washing machine shell and the outer drum. The end of the return pipe away from the filter collection chamber is connected to the outer drum and communicates with the inner area of ​​the outer drum. The end of the inlet pipe away from the filter collection chamber is connected to the outer cylinder and communicates with the internal area of ​​the outer cylinder; The end of the discharge pipe furthest from the filter collection chamber is connected to the drain pipe.

[0025] A method for cleaning clothes, using the aforementioned washing machine, is as follows: During the washing process, the drive device installed on the return pipe is activated, driving the water in the outer drum to flow into the collection and filtration chamber through the inlet pipe and then through the filtration device before returning to the outer drum through the return pipe. During this process, the filtration device traps lint, fuzz, and lint in the water flow, thus achieving the filtration and collection of lint, fuzz, and lint in the water flow. At the same time, the agitation device operates, causing the fluid inside the shell to be in a turbulent state under the action of the drive device and the agitation device on the return pipe. This prevents the lint, fuzz, and lint collected by the filter device from adhering to the filter device, thus avoiding clogging of the filter device. When the lint, fuzz, and lint collected by the filter device need to be discharged, the drive device on the return pipe is turned off, and the drive device on the discharge pipe is turned on. The water in the outer cylinder is driven to flow into the collection and filtration chamber through the inlet pipe and then through the discharge pipe to be discharged from the drain pipe. During this process, the water flow carries the lint, fuzz, and lint collected by the filter device out of the drain pipe with the water flow.

[0026] This invention incorporates a hollow fiber filtration device within the filtration and collection chamber to filter and collect lint, fuzz, woven fabric, and particulate matter. An agitator within the housing tumbles and gathers these lint, fuzz, woven fabric, and particulate matter, adhering to newly attached particles and thus cleaning the device. During discharge, the device is more efficient at removing these particles, minimizing residue buildup and preventing clogging, ensuring continuous and unobstructed operation.

[0027] This invention utilizes an agitation device to continuously tumble undissolved laundry detergent particles within the filter collection chamber. This ensures that the detergent particles constantly contact and impact the inner surface of the hollow filter screen, promoting rapid dissolution. The quickly 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] In this invention, the stirring device drives the filter screen to tumble, so the collected debris does not remain stationary on the hollow filter screen. This invention differs from traditional filter collection devices where the collected pollutants are statically attached. Static attachment in existing technologies easily leads to clogging, resulting in a continuous decline in filtration efficiency.

[0029] This invention utilizes a stirring device to keep the lint, fuzz, lint, and particulate matter entrained in the fluid within the filtration and collection chamber in a dynamic state, preventing them from adhering to the filter screen. This allows the lint, fuzz, lint, and particulate matter to tumble, gather, and adhere to the filter screen within the filtration and collection chamber, thus cleaning the filter screen or hollow filter screen, ensuring smoother filtration, and maintaining the effective collection process.

[0030] 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. Attached Figure Description

Detailed Implementation

[0047] The present invention will be described below with reference to the accompanying drawings. See Figures 1-6 As shown, the present invention provides a filter collection component, including a hollow shell 1, a filter collection chamber provided inside the shell 1, and a hollow filter device provided inside the filter collection chamber; The filtration device divides the filtration collection chamber into a collection area and a filtered area; The housing 1 is also provided with a fluid inlet and a fluid return outlet; The fluid inlet is connected to the collection area, and the fluid return outlet is connected to the filtered area. The housing 1 is also equipped with an agitation device. In use, the fluid enters the filter collection chamber through the fluid inlet, is filtered by the filter device in the collection filter chamber, and then flows out through the fluid return outlet. During this process, impurities contained in the fluid are trapped in the filter collection chamber by the filter device, thus achieving the filtration and collection of impurities in the fluid. The fluid inlet and the fluid return outlet can be connected to the same container, which contains the fluid, thereby achieving the circulation filtration of the fluid in the container. The agitation device increases the turbulence of the fluid in the collection filter chamber, preventing the collected impurities from adhering to the filter device and avoiding the phenomenon that the filtration and collection effect will continuously decrease due to the increase of deposits on the filter device.

[0048] In one embodiment, the housing 1 is further provided with a fluid outlet, which is connected to the collection area. The collected debris is discharged through the fluid outlet.

[0049] In one embodiment, the agitation device includes a drive shaft 9, one end of which extends out of the housing 1 and is connected to a motor 8 that drives the drive shaft 9 to rotate. The motor 8 is fixedly mounted on the housing 1. A stirring blade 10 is fixedly connected to one end of the drive shaft 9 located inside the housing 1; The drive shaft 9 is rotatably and sealed to the housing 1.

[0050] Motor 8 drives transmission shaft 9 to rotate, which in turn drives agitator blade 10 to rotate. This causes the water flow in the area where agitator blade 10 is located to flow in the direction of rotation of agitator blade 10 under the agitation of agitator blade 10, thereby increasing the turbulence of the fluid. Moreover, agitator blade 10 drives the fluid to impact filter screen 2, causing the collected debris to flow towards the center area of ​​the rotating blade, so that the collected debris gathers and avoids the collected debris from adhering to filter screen 2, ensuring that filter screen 2 remains unobstructed, thereby achieving efficient filtration and collection of debris.

[0051] In one embodiment, the agitator blades 10 are located in the internal region of the filter device, such as... Figure 7-13 As shown; In one embodiment, the agitator blade 10 is located in the area between the filter device and the housing 1, such as... Figure 1-6 As shown.

[0052] In one embodiment, the housing 1 is cylindrical, and the agitating device is disposed on the circumferential surface of the housing 1 or on one end of the housing 1.

[0053] In one embodiment, the internal area of ​​the filter device is the collection area; The area between the housing 1 and the filter device is the filtered area, such as... Figure 1-6 As shown, impurities such as lint, thread scraps, and woven lint contained in the fluid are filtered and collected in the internal area of ​​filter screen 2 after being filtered by filter screen 2.

[0054] In one embodiment, the internal area of ​​the filter device is the filtered area; The area between the housing 1 and the filter device is the collection area, such as... Figure 7-13 As shown.

[0055] In one embodiment, such as Figure 7-13 As shown, the housing 1 is provided with a fluid outlet, and a sealing structure is provided between the fluid outlet and the filter device. The sealing structure is a sealing rubber ring 15. The filter screen 2 is provided with an outlet at the position corresponding to the fluid outlet. A cylindrical connector 17 is fixedly and sealed on the fluid outlet, and the sealing rubber ring 15 is provided at the end of the connector 17. When the filter screen 2 is installed in place, the sealing rubber ring 15 is sealed to the outlet, so that the fluid outlet is connected to the outlet through the connector 17 and the sealing rubber ring 15.

[0056] In one embodiment, the filtering device is a cylindrical filter screen 2.

[0057] In one embodiment, the filter device is connected to the housing 1 via a quick-release structure, which allows the filter screen 2 to be easily removed when necessary to clean debris such as lint, fuzz, and woven fabrics attached to the filter screen 2. The quick-release structure includes a connecting seat 11, on which an external thread is provided on the circumferential surface. One end of the housing 1 is provided with a connecting hole 16 that communicates with the filter collection chamber. The connecting hole 16 is provided with an internal thread, and the internal thread and the external thread are matched and connected. A fixed seat is axially fixedly connected to the connecting seat 11; One end of the filter device is fixedly connected to the mounting base; A connecting post is fixedly connected to the side of the fixed base facing the connecting base 11. A through hole is provided on the connecting base 11 at the position corresponding to the connecting post. After the connecting post extends into the through hole, a retaining spring is axially fixedly connected to it. A sealing gasket 13 is provided between the connecting base 11 and the housing 1. Rotate the connecting seat 11. Since the fixed seat and the connecting seat 11 are axially fixedly connected, the connecting seat 11 rotates while the fixed seat does not rotate, thereby realizing the assembly and disassembly of the filter screen 2.

[0058] In one embodiment, the end of the filter device away from the quick-release structure is connected to the housing 1. This end of the filter device away from the quick-release structure can be either sealed or connected to the housing 1 and sealed by the housing 1.

[0059] In one embodiment, the agitator is disposed on one end of the housing 1 and is located in the internal area of ​​the filter device. A sealing ring 14 is provided between the filter device and the end of the housing 1 away from the quick-release structure. It can be configured as follows: a limiting ring groove 12 is provided on the housing 1 at the position corresponding to the end of the filter device away from the quick-release structure, and the limiting ring groove 12 matches the end of the filter device away from the quick-release structure. The end of the filter device away from the quick-release structure extends into the limiting ring groove 12, and a sealing ring 14 is provided between the filter device and the limiting ring groove 12, located within the limiting ring groove 12. The sealing ring 14 can be a rubber sealing ring 14. (See [reference]). Figure 7-13 As shown.

[0060] In one embodiment, a one-way valve 7 is provided at the fluid outlet. This one-way valve 7 ensures that fluid can only flow from inside the housing 1 to the fluid outlet, and that fluid cannot flow in the reverse direction.

[0061] In one embodiment, the filter device is provided with a first positioning surface 3, and the limiting ring groove 12 is provided with a second positioning surface, with the first positioning surface 3 and the second positioning surface corresponding to each other. When the filter device is installed in place, one end of the filter device extends into the limiting ring groove 12, and the first positioning surface 3 and the second positioning surface are matched and connected. The first positioning surface 3 is provided on corresponding sides of the circumferential surface of the filter screen 2, and the second positioning surface is provided on corresponding sides of the limiting ring groove 12. When the end of the filter screen 2 extends into the limiting ring groove 12, the first positioning surface 3 and the second positioning surface on both sides are matched and connected respectively, thereby playing a limiting and guiding role for the filter screen 2; the first positioning surface 3 and the second positioning surface are provided to facilitate smooth installation of the filter screen 2.

[0062] In one embodiment, the filter screen 2 can be installed and guided as follows: a guide post is provided on the circumferential surface of the fixing seat, and a guide groove is provided on the inner wall of the housing 1 along the direction in which the filter screen 2 extends into the filter collection chamber. The guide post is matched and set in the guide groove. The end of the guide groove near the connecting seat 11 is V-shaped to facilitate the insertion of the guide post. When installing the filter screen 2, the guide post is aligned with the guide groove, and the filter screen 2 is inserted into the filter collection chamber. After the filter screen 2 is installed in place, the connecting seat 11 is rotated to connect the connecting seat 11 to the housing 1 by thread, thereby fixing the filter screen 2. When it is necessary to remove the filter screen 2, the connecting seat 11 is rotated in the opposite direction, the connecting seat 11 is disengaged from the housing 1, and the filter screen 2 can be pulled out.

[0063] In one embodiment, a filtration and collection system includes the aforementioned filtration and collection component, wherein an inlet pipe 5 is connected to the fluid inlet, a return pipe 4 is connected to the fluid return outlet, and a discharge pipe 6 is connected to the fluid outlet. Both the return pipe 4 and the discharge pipe 6 are equipped with driving devices to drive the fluid flow. This utility model provides a filtration and collection system suitable for use in washing machines, dryers, dryer combos, aquariums, and other applications requiring the filtration and collection of impurities such as lint, fibers, and fabric fibers from fluids.

[0064] In one embodiment, a washing machine includes a washing machine housing 19 and an outer drum 20. A drain pipe is connected to the outer drum 20. A filter collection system is provided in the area between the washing machine housing 19 and the outer drum 20. The end of the return pipe 4 away from the filter collection chamber is connected to the outer drum 20 and communicates with the internal area of ​​the outer drum 20. The end of the inlet pipe 5 away from the filter collection chamber is connected to the outer cylinder 20 and communicates with the internal area of ​​the outer cylinder 20; The end of the discharge pipe 6 away from the filter collection chamber is connected to the drain pipe.

[0065] During the washing process, the drive device installed on the return pipe 4 is activated, driving the water in the outer drum 20 to flow into the collection and filtration chamber through the inlet pipe 5 and then through the filter device before returning to the outer drum 20 through the return pipe 4. During this process, the filter device traps the lint, fuzz, and lint in the water flow, thus achieving the filtration and collection of lint, fuzz, and lint in the water flow. At the same time, the agitation device operates, causing the fluid inside the shell 1 to be in a turbulent state under the action of the drive device and the agitation device on the return pipe 4. This allows the undissolved detergent particles to dissolve quickly under the action of the rotating agitator blade 10. The quickly dissolved detergent particles are then returned to the inner area of ​​the outer drum 20 through this invention, which allows them to fully and completely penetrate the clothes, improving the cleaning effect of the clothes. This makes it convenient for users to select the quick wash mode to ensure the cleaning effect of the clothes. The agitating blade 10 rotates, simultaneously peeling off the lint, fuzz, and fibrous material adhering to the filter screen 2, and causing them to move closer to and gather towards the center of the agitating blade 10. The gathered lint, fuzz, and fibrous material facilitates more thorough discharge, making it less likely for lint, fuzz, and fibrous material to remain on the filter screen 2. Furthermore, it avoids the phenomenon that the filtration and collection effect will continuously decrease due to the increase of adhering material on the filter screen 2.

[0066] At the same time, it avoids overloading of the motor 8 caused by lint, fuzz, and fibrous material adhering to the filter screen 2, which would shorten the service life of the motor 8.

[0067] When the lint, fuzz, and lint collected by the filter screen 2 need to be discharged, the drive device on the return pipe 4 is closed, and the drive device on the discharge pipe 6 is opened. The water in the outer cylinder 20 is driven to flow into the collection and filtration chamber through the inlet pipe 5 and then through the discharge pipe 6 to be discharged from the drain pipe. During this process, the water flow carries the lint, fuzz, and lint collected by the filter device to be discharged from the drain pipe with the water flow. The drive device is the water pump 18.
