Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration and collection technology, and more particularly to the field of clothing cleaning technology, specifically 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, 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. Utility Model Content
[0010] To address the aforementioned problems, this utility model provides a simple, easy-to-use filtration and collection device and washing machine that can efficiently filter and collect impurities in fluids, ensuring collection efficiency.
[0011] This utility model discloses a filtration and collection device, which includes a filtration and collection body, a filtration and collection chamber, and a filtration device disposed within the filtration and collection chamber. The filtration device divides the internal area of the filtration collection chamber into a collection area and a filtered area. The filter collection body is connected to a first channel and a second channel, which are set to introduce fluid into the collection area, pass through the filter device, enter the filtered area, and then flow out. The second channel and / or the first channel are provided with a drive device for driving fluid flow.
[0012] Preferably, the filtration device includes two filter valves, and the area between the two filter valves is a collection area; When fluid enters the collection area through the filter valve, the filter valve is in the open state; When fluid enters the filtered area through the filter valve, the filter valve is in the closed state.
[0013] Preferably, the filter valve includes an annular valve core body, which is matched and disposed in the filter collection chamber, and a filter screen is blocked and fixedly disposed in the central area of the valve core body; It also includes a state switching device that drives the valve core body to rotate so that the filter valve is in an open or closed state.
[0014] Preferably, the state switching device includes a rotating shaft, one end of which passes through the filter collection body, extends into the filter collection chamber, and is fixedly connected to the circumferential surface of the valve core body; the other end of the rotating shaft is connected to a drive motor that drives the rotating shaft to rotate. The rotating shaft is movably and sealedly connected to the filter collection body.
[0015] Preferably, the filter valve includes an annular base and an opening / closing valve plate, with a through hole at the center of the annular base, and the annular base is matched and disposed in the filter collection chamber; The valve plate is provided with a through hole for fluid to flow through, and a filter screen is provided to seal the through hole. The opening and closing valve plate is matched with the annular base, and one end of the opening and closing valve plate is rotatably connected to the annular base via a pin. When fluid impacts the valve plate, the valve plate rotates, moving closer to the annular base and blocking the through hole to close the filter valve, or separating from the annular base and opening the through hole to open the filter valve.
[0016] Preferably, the driving device is a driving device that drives the fluid to flow in one direction or drives the fluid to flow in both forward and reverse directions within one cycle.
[0017] Preferably, the filtering device is a hollow filter screen, with both ends of the filter screen connected to the filter collection body, the collection area located inside the filter screen, and the area located inside the filter collection chamber and outside the filter screen is the filtered area. The first channel is connected to the filter collection body at one end, which is connected to the internal area of the filter screen. The second channel is connected to the filter collection body at one end, which is connected to the filtered area.
[0018] Preferably, there are two second channels, which extend into the filter collection chamber from both sides and are connected to the filtered area. Each of the second channels is equipped with a drive device, and the two drive devices located on the second channel alternately drive the fluid to flow out.
[0019] Preferably, it also includes a discharge channel, one end of which is connected to the filter collection body and communicates with the collection area, and a discharge pump is provided on the discharge channel.
[0020] Preferably, it also includes a discharge channel, one end of which is connected to the filter collection body and communicates with the collection area, and a discharge pump is provided on the discharge channel; The first channel is connected to one end of the filter screen, and the discharge channel is connected to the other end of the filter screen.
[0021] A washing machine includes a washing machine housing, an outer drum disposed inside the washing machine housing, an inner drum disposed inside the outer drum, and a drain pipe connected to the outer drum. The washing machine housing is characterized by having a filter collection device fixedly disposed in the area between the washing machine housing and the outer drum. The ends of the first and second channels away from the filter collection body are fixedly connected to the outer cylinder and communicate with the internal area of the outer cylinder. The end of the discharge channel furthest from the filter collection body is connected to a drain pipe.
[0022] 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.
[0023] This utility model has a simple structure and is easy to use. It drives the fluid to flow out from the second channel or the first channel, or the driving device drives the fluid to flow out from the first channel and the second channel alternately. The filter device installed in the filter collection chamber can be used to filter and collect impurities.
[0024] This invention utilizes the coordinated opening and closing of two filter valves to achieve reciprocating dynamic movement of impurities in the fluid within the filtration and collection area, thereby enabling the collection of impurities without them adhering to the filter screen. This avoids clogging of the filter screens of the two filter valves, 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 drive device.
[0025] This utility model utilizes a state switching device to open or close the valve core body, thereby achieving the filtration and collection of impurities or the rinsing of the filter screen on the valve core body. It has a self-cleaning function, prevents the filter screen from clogging, and keeps the filter screen in a constantly unobstructed state, which is conducive to achieving efficient collection and filtration of impurities.
[0026] This invention utilizes a driving device to redirect fluid, thereby causing the impurities collected in the filtration and collection chamber between two filter valves to become fluid. Unlike traditional filtration and collection devices where pollutants are statically attached, this invention addresses the drawback of static attachment in existing technologies, which easily leads to clogging and consequently a continuous decline in filtration and collection efficiency.
[0027] This invention utilizes a driving device to drive fluid through a filter screen, which then flows alternately out from two filter valves or two second channels in the filter collection chamber. This allows the lint, fuzz, lint, and particulate matter entrained in the fluid within the filter collection chamber to remain in a dynamic state, no longer adhering to the filter screen. This causes the lint, fuzz, lint, and particulate matter to tumble, accumulate, and adhere to the filter screen or hollow filter screen on the filter valve within the filter collection chamber, thus cleaning the filter screen or hollow filter screen, ensuring smoother flow, and maintaining the effective collection process.
[0028] 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.
[0029] This invention, when filtering and collecting lint, fuzz, woven lint, and particulate matter, tumbles, adheres to, and aggregates these materials. During the discharge process, it facilitates the removal of lint, fuzz, woven lint, and particulate matter, minimizing residue buildup on the filter screens of the first and second filtration devices and preventing filter clogging.
[0030] This invention utilizes two filter valves or hollow filter screens to filter and collect impurities in the fluid. Simultaneously, due to the fluid's alternating flow within the filter collection chamber, undissolved detergent particles continuously flow within the chamber. This causes the detergent particles to constantly contact and impact the two filter valves or hollow filter screens, 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 efficiency.
[0031] In the process of collecting and filtering debris, this invention features a filter valve that is open when fluid enters the collection area and closed when fluid enters the post-filtration area. This allows the fluid to flush the filter screens on both filter valves, preventing clogging. When the collected debris is discharged, a discharge pump drives the fluid to flow out, further flushing the filter screens on both filter valves and preventing clogging. This eliminates the need for manual cleaning and reduces the user's cleaning workload. Attached Figure Description

Detailed Implementation
[0050] The present invention will be described below with reference to the accompanying drawings.
[0051] This utility model discloses a filtration and collection device, including a filtration and collection body 1, a filtration and collection chamber is provided inside the filtration and collection body 1, and a filtration device 2 is provided inside the filtration and collection chamber. The filtration device 2 divides the internal area of the filtration collection chamber into a collection area and a filtered area. The filter collection body 1 is connected to a first channel 11 and a second channel 12, which are set up to introduce fluid into the collection area, pass through the filter device 2, enter the filtered area and then flow out. The second channel 12 and / or the first channel 11 are provided with a drive device for driving fluid flow.
[0052] In use, the fluid is guided to the filter collection chamber and returned to the original container by the first channel 11 and the second channel 12. During this process, when the fluid passes through the filter collection chamber, the filter collection device 2 is used to filter and collect the impurities in the fluid, and the impurities are retained in the collection area.
[0053] The first channel 11 and the second channel 12 are respectively connected to the filter collection body 1 via quick connectors 5, so as to inspect or disassemble the filter collection body 1. The quick connectors 5 are connected to the filter collection body 1 via flanges 6.
[0054] See Figures 2-3 As shown, the filter device 2 includes two filter valves, and the area between the two filter valves is the collection area; When fluid enters the collection area through the filter valve, the filter valve is in the open state; thus, it does not obstruct the flow of fluid, and the fluid flows smoothly into the filtration area. When the fluid enters the post-filtration area through the filter valve, the filter valve is in a closed state, so that the fluid can only pass through the closed filter valve to achieve the filtration and collection of fluid impurities.
[0055] like Figures 4-5 As shown, in one embodiment, the filter valve includes an annular valve core body 8, which is matched and disposed in the filter collection chamber, and a filter screen 3 is blocked and fixedly disposed in the central area of the valve core body 8. It also includes a state switching device that drives the valve core body 8 to rotate so that the filter valve is in an open or closed state.
[0056] The state switching device includes a rotating shaft. One end of the rotating shaft passes through the filter collection body 1, extends into the filter collection chamber, and is fixedly connected to the circumferential surface of the valve core body 8. The other end of the rotating shaft is connected to a drive motor 7 that drives the rotating shaft to rotate. The rotating shaft is movably and sealedly connected to the filter collection body 1.
[0057] The drive motor 7 drives the rotating shaft to rotate as needed, thereby causing the valve core body 8 to block the filter collection chamber to achieve the purpose of filtration or to guide the fluid through the filter collection chamber; when the valve core body 8 blocks the filter collection chamber, the fluid can only pass through the filter screen 3 in the central area of the valve core body 8 and flow through the valve core body 8 to achieve the filtration and collection of impurities in the fluid. The drive device is connected to the valve core body 8 via a rotating shaft. The drive device drives the rotating shaft to reciprocate in one or two directions with a rotation angle of 0-360 degrees. The drive device drives the rotating shaft to switch the state of the filter valve, opening or blocking the filter collection chamber. The drive device drives the rotating shaft to reciprocate, thereby causing the filter screen 3 to swing back and forth inside the filter valve, achieving better flushing of the debris attached to the filter screen 3, effectively preventing the filter screen 3 from clogging, and maintaining good fluid flow through the filter screen 3.
[0058] When this invention is applied to a washing machine, the water inside the outer drum flows through the filter screen 3 to filter and collect lint, fabric lint, and other debris. During this process, the detergent particles, upon entering the outer drum, are not completely dissolved. This invention simultaneously filters and collects lint, fabric lint, and other debris in the water flow at the beginning of the washing cycle. Thus, undissolved detergent particles remain in the filter collection chamber. The drive device causes the fluid to flow back and forth, and simultaneously, two filter valves in the filter collection chamber operate alternately, one open and the other closed. The reciprocating flow of the fluid in the filter collection chamber causes the undissolved detergent particles to be removed. The detergent particles dissolve within the filter collection chamber, avoiding the problem of detergent particles being collected in existing technologies, and the resulting decrease in cleaning ability. It also avoids the problem of detergent being foamed before entering the outer drum to prevent particle collection, which leads to clothes being difficult to rinse due to excessive foam. Drum washing machines use less water and rely entirely on the lifting ribs to lift and tumble the clothes to achieve cleaning. Excessive foam can also make the inner drum wall and lifting ribs smoother than before, thus reducing the washing machine's ability to lift and tumble the clothes, resulting in a weakened cleaning ability.
[0059] This invention activates the filter device simultaneously during the washing process, enabling the filtration and collection of lint, fuzz, and other debris in the early stages of garment washing. This prevents lint, fuzz, and other debris from adhering to the inner and outer drums earlier, significantly reducing dirt accumulation in the area between the inner and outer drums. This effectively reduces bacterial growth, minimizes secondary contamination of garments, and prevents lint, fuzz, and other debris from clogging the filter screen, thus shortening the washing time.
[0060] In one embodiment, see Figures 8-9As shown, the filter valve includes an annular base 10 and an opening / closing valve plate 9. The annular base 10 has a through hole at its center and is matched and installed in the filter collection chamber. The valve plate 9 is provided with a through hole for fluid to flow through, and a filter screen 3 is provided to seal the through hole. The opening and closing valve plate 9 is matched with the annular base 10, and one end of the opening and closing valve plate 9 is rotatably connected to the annular base 10 through a pin. When fluid impacts the opening and closing valve plate 9, the opening and closing valve plate 9 rotates. The opening and closing valve plate 9 approaches the annular base 10 and blocks the through hole, so that the filter valve is in the closed state, or it separates from the annular base 10 and opens the through hole, so that the filter valve is in the open state. When the filter valve is in the closed state, the fluid flowing through the filter valve can only pass through the filter screen 3 on the opening and closing valve plate 9, so as to filter and collect impurities in the fluid.
[0061] In one embodiment, the driving device is a driving device that drives the fluid to flow in one direction or drives the fluid to flow in both the forward and reverse directions within one cycle, and the two filter valves of the filter device 2 are the first filter valve and the second filter valve, respectively. When the driving device drives the fluid to flow in one direction, the fluid in the container flows out through the first channel 11, passes through the first filter valve which is in the open state, enters the collection area of the filter collection device 2, and then passes through the second filter valve which is in the closed state. At this time, the fluid can only enter the filtered area through the filter screen 3 on the second filter valve, thus realizing the filtration and collection of impurities in the fluid. Then it flows out through the second channel 12. During this process, the filter device 2 filters and collects impurities in the fluid, and the impurities remain in the collection area. When the driving device drives the fluid to flow in both the forward and reverse directions within one cycle, in the first half of the cycle, the driving device drives the fluid to flow in the forward direction. After the fluid in the container flows out through the first channel 11, it passes through the first filter valve which is in the open state and enters the collection area of the filter collection body 1. Then it passes through the second filter valve which is in the closed state. At this time, the fluid can only enter the filtered area through the filter screen 3 on the second filter valve. In this way, the impurities in the fluid are filtered and collected. Then it flows out through the second channel 12. During the remaining half of a cycle, the drive device drives the fluid to flow in the reverse direction, and the filter valve in the filter collection chamber switches states. After the fluid in the container flows in through the second channel 12, it passes through the second filter valve, which is in the open state. When the fluid passes through the second filter valve, it washes away the debris adhering to the second filter valve, keeping the filter screen 3 on the filter valve unobstructed. This effectively prevents clogging when using the second filter valve to filter debris in the next cycle. The fluid then enters the collection area of the filter collection body 1 and then passes through the first filter valve, which is in the closed state. At this time, the fluid can only enter the filtered area through the filter screen 3 on the first filter valve. This achieves the filtration and collection of debris in the fluid. The fluid then flows out through the first channel 11 and flows back out. This cycle repeats, achieving the filtration and collection of debris in the fluid in the container.
[0062] In one embodiment, see Figures 10-11 As shown, the filter device 2 is a hollow filter screen 3, a cylindrical filter screen 3, or a conical filter screen 3. Both ends of the filter screen 3 are connected to the filter collection body 1. The collection area is located inside the filter screen 3. The area located inside the filter collection chamber and outside the filter screen 3 is the filtered area. The first channel 11 is connected to one end of the filter collection body 1 and is connected to the internal area of the filter screen 3. The second channel 12 is connected to one end of the filter collection body 1 and is connected to the filtered area.
[0063] See Figures 10-11 As shown, there are two second channels 12. The two second channels 12 extend into the filter collection chamber from both sides and are connected to the filtered area. Each of the second channels 12 is equipped with a drive device, and the two drive devices located on the second channel 12 alternately drive the fluid to flow out. The drive device can be a water pump 13.
[0064] During use, the water pumps on the two second channels 12 operate alternately, causing the fluid that enters the filter collection chamber through the first channel 11 to flow out alternately from the two second channels 12 after passing through the filter screen. In this process, the fluid in the filter collection chamber flows back and forth, achieving the filtration and collection of impurities in the fluid, while avoiding the impurities from clogging the filter screen. This repeated cycle, with the fluid flowing in alternating directions, facilitates the reciprocating flow of collected debris within the filter collection chamber, making it easier for debris to accumulate. The accumulated debris then adheres to newly collected debris on the filter screen 3, cleaning the filter screen 3 and further preventing clogging. The filter screen 3 ensures unobstructed flow in real time, achieving efficient collection, while also promoting the dissolution of particulate cleaning agents such as laundry detergent.
[0065] In one embodiment, a discharge channel 15 is further included. One end of the discharge channel 15 is connected to the filter collection body 1 and communicates with the collection area. A discharge pump 18 is provided on the discharge channel 15. In use, the discharge pump 18 is turned on as needed, and fluid flows out through the discharge channel 15. During this process, the discharge pump 18 discharges the debris collected in the collection area. In use, the discharge channel 15 can be connected to the filter collection body via a quick-connect connector 4.
[0066] In one embodiment, the system further includes a discharge channel 15, one end of which is connected to the filter collection body and communicates with the collection area, and a discharge pump 18 is provided on the discharge channel 15. The first channel is connected to one end of the filter screen 3, and the discharge channel 15 is connected to the other end of the filter screen 3; The filter screen is a hollow filter screen, and the cross-sectional area of the internal channel of the discharge pipe 15 is greater than or equal to the cross-sectional area of the internal channel where the filter screen 3 is connected to the discharge pipe 15, so that the collected debris can be discharged without obstruction.
[0067] The filter screen is designed in a cone shape. When the fluid enters the filter screen 3, it impacts the inner wall of the filter screen, increasing the flow rate. This helps to ensure that impurities adhere to the inner wall of the filter screen 3. Each time the fluid is discharged from the outer cylinder, the cleanliness of the filter screen 3 is maintained, thus keeping the filter screen 3 unobstructed, achieving efficient collection, avoiding the need for users to repeatedly disassemble and clean the filter screen 3, and improving the user experience.
[0068] A washing machine includes a washing machine housing 16, an outer drum 17 disposed inside the washing machine housing 16, an inner drum disposed inside the outer drum 17, a drain pipe connected to the outer drum 17, and a filter collection device 2 fixedly disposed in the area between the washing machine housing 16 and the outer drum 17. The ends of the first channel 11 and the second channel 12 that are away from the filter collection body 1 are fixedly connected to the outer cylinder 17 and are connected to the internal area of the outer cylinder 17. The end of the discharge channel 15 away from the filter collection body 1 is connected to the drain pipe.
[0069] The filter collection body 1 is horizontally set inside the washing machine, so that the height at which water flows into the filter collection chamber and the height at which it flows out of the filter collection chamber are on the same horizontal line. This helps to prevent detergent particles from depositing in the filter collection chamber and avoids weakening the fluid's carrying capacity for detergent particles during the reciprocating flow of the fluid, thereby effectively preventing a decrease in the ability to dissolve detergent particles.
[0070] When the filter device 2 is a filter valve, solenoid valves can be installed on the first channel 11, the second channel 12, and the discharge channel respectively. During the washing or rinsing of clothes, the driving device is a water pump 13. The solenoid valves on the first channel 11 and the second channel 12 are opened, and the water pump 13 drives the water inside the outer drum 17 of the washing machine to enter the filter collection chamber through the first channel 11. The filter device 2 is used to filter and collect the impurities in the water flow. The water flow after passing through the filter device 2 flows back to the inner area of the outer drum 17 of the washing machine through the second channel 12. To effectively prevent debris in the water flow from clogging the filter screen 3, and to effectively improve the dissolution of detergent or laundry powder in the water flow, and to avoid accidentally collecting particulate detergent or laundry powder when using this device to filter and collect debris, the water pump 13 can drive the water flow in both forward and reverse directions within one cycle: In the first half of the cycle, water flows through the first channel 11 into the filter collection chamber, and then flows back through the second channel 12 to the inner area of the outer drum 17 of the washing machine, thus filtering and collecting impurities in the water. At the same time, impurities and larger particles of laundry detergent or cleaning agent are also retained in the filter collection chamber. In the second half of the cycle, water flows through the second channel 12 into the filter collection chamber, and then flows back through the first channel 11 to the inner area of the outer drum 17 of the washing machine. The water flow reverses, flushing the filter screen 3 that has played a role in filtering impurities in the first half of the cycle. This causes the impurities on the filter screen 3 to move with the water flow toward another filter screen 3, and the filter screen 3 is used to filter and collect the impurities, preventing the impurities from clogging the filter screen 3. During this process, the granular cleaning agent or laundry detergent retained in the filter collection chamber also moves with the water flow in the opposite direction, thereby effectively improving the dissolution of the cleaning agent or laundry detergent and preventing the collection of laundry detergent or cleaning agent.
[0071] When filter device 2 is a hollow filter screen, such as Figure 16-17 As shown, the water pumps on the two second channels 12 operate alternately, causing the water in the outer drum of the washing machine to flow through the first channel 11 into the filter collection chamber. After passing through the filter screen, the water flows out alternately from the two second channels 12. During this process, the water flow in the filter collection chamber changes direction back and forth, thereby achieving the filtration and collection of impurities in the fluid. This also prevents impurities from clogging the filter screen and facilitates the dissolution of detergents such as laundry detergent in the water.
[0072] In one embodiment, the hollow filter screen can be detachably connected to the filter collection body 1: for example, one end of the filter collection body 1 is connected to the discharge channel 15, and fixed rings are fixedly connected to both ends of the filter screen. Sealing sleeves are connected to the fixed rings. When the filter screen is placed inside the filter collection body 1, both ends of the filter screen are sealed to the filter collection body 1 through sealing rings. The sealing rings are located on the circumferential surface of the fixed rings. One end of the filter screen is sealed to the discharge channel 15, and a bracket is fixedly connected to the fixed ring at the other end. A flow port is provided on the bracket, and a first channel 11 is located on the circumferential surface of one end of the filter collection body 1. The flow port and the internal area of the fixed ring are connected to the internal area of the filter screen. A screw plug is provided at the end of the bracket away from the filter screen, and a screw hole is provided at the end of the filter collection body 1. After the filter screen extends into the screw hole and enters the filter collection chamber, and its end is sealed to the discharge channel 15, the other end is threadedly connected to the screw hole through the screw plug, thus achieving a detachable connection between the filter screen and the filter collection body. Figure 17 As shown.
[0073] When the debris in the filter collection chamber needs to be discharged, open the solenoid valve on the discharge channel 15 and start the discharge pump 18. During the water discharge process, the debris is discharged from the drain pipe together with the water. In use, both the first channel 11 and the second channel 12 are equipped with foreign object interceptors 14. The foreign object interceptor 14 is a prior art foreign object interceptor 14, mainly used to filter larger foreign objects, such as coins in a washing machine. Its structure can be configured as follows: it includes a hollow cylindrical cleaning body, which is connected to the required pipe. 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 foreign objects, such as coins, from flowing through the hollow cylindrical cleaning body, thus trapping them inside. By rotating the screw plug, the foreign object is removed.
[0074] In one embodiment, two filter collection devices 2 are configured, symmetrically arranged vertically about the rotation axis of the inner drum. The discharge channels 15 on the two filter collection devices 2 are interconnected and connected to the drain pipe. Using two filter collection devices 2 effectively improves the filtration and collection efficiency of impurities in the water flow inside the washing machine. Alternatively, the two filter collection devices 2 can be used separately during the washing and rinsing processes. The mesh size of the filter screen 3 on the filter device 2 can be selected as needed.
