Description

Technical Field

[0001] This utility model relates to the field of filtration and collection, specifically to a filter element and a filter collection component. 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, thus reducing the value of washing and caring for the clothes. 3. Long-term washing and rinsing of clothes will cause unnecessary mechanical and physical wear and tear on the equipment and unnecessary consumption of the 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 the rinsing and cleaning effect and ability 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 grime: 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 year-round 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 filter element and a filter collection component that improve filtration efficiency and prevent filter clogging.

[0011] This utility model discloses a filter element, including a hollow filter body, the internal area of ​​which is a filter collection chamber. The filter body is provided with a fluid inlet for fluid inflow. An annular partitioned sealing structure is provided on the outer peripheral surface of the filter body. One end of the partitioned sealing structure is fixedly connected to the peripheral surface of the filter body, and a filter screen is provided inside the partitioned sealing structure at a position corresponding to the filter body.

[0012] Preferably, it also includes a fluid outlet, wherein the fluid inlet and the fluid outlet are respectively disposed at corresponding ends of the filter body.

[0013] Preferably, the filter body is cylindrical.

[0014] Preferably, the filter body is cone-shaped.

[0015] Preferably, the cross-section of the filter body is polygonal.

[0016] Preferably, at least two partitioned sealing structures are provided on the circumferential surface of the filter body.

[0017] Preferably, the partition sealing structure is an elastic element.

[0018] Preferably, the filter body is set horizontally.

[0019] Preferably, the filter body located outside the partitioned sealing structure is a hollow solid.

[0020] A filter collection device includes a housing, in which a filter element is disposed, and a fluid return port is provided on the housing. The end of the partitioned sealing structure away from the filter body extends toward the inner wall of the housing and is sealed to the inner wall of the housing. The fluid return port is connected to the area on the filter body where the filter screen is set through a partitioned sealing structure. The fluid return port is matched with the filter screen.

[0021] Preferably, the housing is connected to a filter element via a quick-release structure.

[0022] This invention utilizes an annular partitioned sealing structure on the outer circumference of the filter screen to reduce the filtration and collection area. Fluid flows out through this structure, allowing for faster and better accumulation of lint, fuzz, lint, and particulate matter, especially when the content is low or the user-set washing time is short. Simultaneously, these lint, fuzz, lint, and particulate matter tumble, accumulate, and adhere to the filter screen within the collection chamber, thus cleaning the screen, ensuring smoother flow, and maintaining optimal collection efficiency. Ultimately, this benefits filtration and collection. The post-collection cleaning and discharge also helps prevent lint, lint, fabric debris, and particulate matter from adhering to the filter collection chamber outside the filter screen. At the same time, it avoids undissolved detergent particles adhering to the filter collection chamber outside the filter screen, which would cause the undissolved detergent particles to be diluted during the washing process. The annular partitioned sealing structure on the outer circumference of the filter screen intensifies the aggregation, tumbling, and friction of undissolved detergent particles, promoting the dissolution of detergent particles. This allows the quickly dissolved detergent particles to circulate back into the washing machine for cleaning clothes, efficiently dissolving them and fully utilizing them to clean sweat stains and dirt on clothes.

[0023] The filter body of this utility model has at least two partitioned sealing structures on its circumferential surface. Fluid flows out alternately from the two partitioned sealing structures, and the fluid concentrates between the two partitioned sealing structures to generate more sufficient fluidity, which improves the effect of gathering and tumbling of lint, fuzz, lint, and pollutant particles, and increases the gathering speed of lint, fuzz, lint, and pollutant particles, so as to achieve efficient accumulation of lint, fuzz, lint, and pollutant particles, making them easier to discharge and ensuring that the filter screen is clean and unobstructed. At the same time, the fluid concentrates between the two partitioned sealing structures to generate more sufficient fluidity, which promotes the rapid dissolution of undissolved laundry detergent particles.

Detailed Implementation

[0029] The present invention will be described below with reference to the accompanying drawings.

[0030] See Figure 1 As shown, this utility model discloses a filter element, including a hollow filter body 1. The internal area of ​​the filter body 1 is a filter collection chamber. The filter body 1 is provided with a fluid inlet for fluid inflow. An annular partitioned sealing structure 3 is provided on the outer circumferential surface of the filter body 1. One end of the partitioned sealing structure 3 is fixedly connected to the circumferential surface of the filter body 1, and a filter screen 4 is provided inside the partitioned sealing structure 3 at a position corresponding to the filter body 1. By using the filter screen 4 provided inside the partitioned sealing structure 3, the fluid passing through the filter screen 4 can only flow out from inside the partitioned sealing structure 3. The filter screen 4 is partially provided on the filter body 1, which reduces the area where impurities adhere to the filter screen 4, reducing the difficulty of cleaning the filter collection chamber when the fluid is discharged.

[0031] In one embodiment, a fluid outlet is also included, wherein the fluid inlet and the fluid outlet are respectively disposed at opposite ends of the filter screen 4, and the collected debris is discharged using the fluid outlet.

[0032] In one embodiment, the filter body 1 is cylindrical.

[0033] In one embodiment, the filter body is cone-shaped.

[0034] To increase the tumbling and agitation of collected debris within the filter screen 4, the filter body 1 can be configured as follows: the cross-section of the filter body 1 is polygonal. During use, after the fluid enters the filter body 1, it can only flow out through the filter screen 4. Setting the cross-section of the filter body 1 to a polygonal shape causes the fluid to tumble during flow, thus preventing debris in the fluid from clogging the filter screen 4, cleaning the filter screen 4, ensuring its unobstructed flow, and achieving efficient collection capabilities.

[0035] In one embodiment, such as Figure 1As shown, at least two partitioned sealing structures 3 are provided on the circumferential surface of the filter body 1. The two partitioned sealing structures 3 are respectively connected to a return outlet, and the fluid flows out alternately from the two return outlets, thereby causing the fluid in the filter body 1 to change direction and enhance the tumbling of lint, lint, particulate pollutants and undissolved detergent particles carried by the fluid in the filter body 1. This achieves rapid dissolution of undissolved detergent particles, and the accumulation and adhesion of lint, lint, and particulate pollutants to the inner wall of the filter screen 4. The continuously newly collected lint, lint, and particulate pollutants achieve efficient cleaning of the filter screen 4 and ensure the unobstructed flow of the filter screen 4 in real time.

[0036] In one embodiment, the filter body 1 located outside the partition sealing structure 3 is a hollow solid, which prevents fluid from flowing out of the filter body 1 outside the partition sealing structure 3, and the fluid can only flow out from the filter screen inside the partition sealing structure 3; at the same time, it makes the inner wall of the filter body 1 smoother and flatter, so that lint, shavings and particulate pollutants are not easily attached to the inner wall of the filter body 1, and when the fluid impacts the inner wall of the filter body 1, it is easier to carry away lint, shavings and particulate pollutants.

[0037] In one embodiment, the partition sealing structure 3 is an elastic element.

[0038] Filter body 1 is set horizontally.

[0039] See Figure 2 As shown, a filter collection device includes a housing 7, in which a filter element is disposed, and a fluid return port is provided on the housing 7. The end of the partition sealing structure 3 away from the filter body 1 extends toward the inner wall of the housing 7 and is sealed to the inner wall of the housing 7. The fluid return port is connected to the area on the filter body 1 where the filter screen 4 is installed through the partitioned sealing structure 3. The fluid return port is matched with the filter screen, and the shape and size of the fluid return port are the same as those of the filter screen. The fluid return port is flat or slit-shaped and is arranged on the housing 7 along the axial direction of the filter body 1.

[0040] During use, fluid flows into the filter body 1 from the fluid inlet and flows into the return outlet and is discharged through the partitioned sealing structure 3 on the periphery of the filter body 1. During this process, the filter screen 4 located in the partitioned sealing structure 3 filters and collects impurities in the fluid. When two return outlets are provided, the fluid flows out alternately from the two return outlets, which increases the tumbling and accumulation of debris in the filter body 1. At the same time, the filter body 1 is partially equipped with filter screens 4, which reduces the area on which debris adheres to the filter screens 4, reducing the difficulty of cleaning the filter collection chamber when the fluid is discharged. Because the filter body 1 is partially equipped with filter screens 4, the collected debris will accumulate in a local area of ​​the filter collection chamber, making it easier to clean the filter collection chamber during drainage. The specific implementation of the fluid flowing out alternately from the two return outlets is to install a pump on the return pipe connected to the two return outlets. When the collected debris needs to be discharged, the fluid flows into the filter body 1 from the fluid inlet and then flows out directly from the fluid outlet, simultaneously discharging the debris inside the filter body 1.

[0041] The housing is connected to a filter element via a quick-release mechanism.

[0042] In practical use, the housing 7 is detachably connected to a filter element via a quick-release structure; The quick-release structure includes fixing rings at both ends of the filter body 1, namely a first fixing ring and a second fixing ring. The fluid inlet is connected to the filter collection chamber through the first fixing ring, and the fluid outlet is connected to the filter collection chamber through the second fixing ring. The housing 7 has mounting areas at both ends, and the first fixing ring and the second fixing ring are rotatably and sealingly installed in the mounting areas at both ends of the housing 7. A connecting seat 10 is connected to the end of the first fixed ring away from the filter collection chamber by a bracket. The bracket and the connecting seat 10 are rotatably connected by an axial fixing structure. The connecting seat 10 has external threads, and the bracket is provided with an overflow port; The fluid inlet is located on the circumferential surface of one end of the housing 7 and is connected to the filter collection chamber through the flow port and the internal area of ​​the first fixing ring. The end of the housing 7 near the fluid inlet is provided with a connecting hole 5, which is connected to the installation area where the first fixing ring is located. The connecting hole 5 is provided with an internal thread, and the connecting seat 10 is threadedly connected to the connecting hole 5. The axial fixing structure includes connecting columns. See Figure 3 As shown, the connecting seat 10 includes a connecting seat body 12 and an end cap 11. The connecting seat body 12 and the end cap 11 are fixedly connected by screws. The connecting post is fixedly provided at the center of one end of the bracket near the connecting seat body 12. The connecting post passes through a matching through hole on the connecting seat body 12 and is axially fixedly connected to the connecting seat body 12 by a snap ring 13. The connecting post is rotatably connected to the through hole.

[0043] A key 6 is provided on the end of the filter body 1 away from the connecting seat 10, and a keyway is provided on the corresponding installation area of ​​the housing 7. When the key 6 is located in the keyway, the partition sealing structure 3 on the filter body 1 is connected to the return outlet on the housing 7. When the filter body 1 is installed in the housing 7, after aligning the key 6 with the keyway, the filter body 1 is inserted into the housing 7 through the connecting hole 5. After the key 6 on the filter body 1 is inserted into the keyway on the housing 7, the end cover 11 is rotated, and the connecting seat body 12 is threadedly connected to the connecting hole 5, so that the housing 7 is detachably connected to a filter element.

[0044] In one embodiment, the cross-sectional area of ​​the internal channel of the fluid inlet is greater than or equal to the cross-sectional area of ​​the internal channel at the end of the filter collection chamber connected to the fluid inlet.

[0045] The cross-sectional area of ​​the internal channel of the discharge channel is greater than or equal to the cross-sectional area of ​​the internal channel at the end of the fluid discharge port connected to the filter collection chamber.

[0046] like Figure 4 The filtration and collection system shown has solenoid valves installed in the fluid inlet channel 8, the return channel, and the discharge channel. The solenoid valves open or close synchronously with the pumps in their respective channels.

[0047] The fluid inlet channel 8 and the fluid outlet channel are connected to both ends of the housing 7 and communicate with the internal area of ​​the filter body 1. The return outlet on the periphery of the housing 7 is connected to the return channel 14 through the return connector 2. There are two return channels 14, and pumps are installed on the two return channels 14 respectively. The fluid flows out of the two return channels 14 alternately and filters and collects impurities in the fluid through the filter screen 4 on the filter body 1. When it is necessary to discharge the collected impurities, the pump on the return channel 14 stops operating and the pump on the fluid outlet channel 9 starts operating. The fluid is discharged from the fluid outlet channel 9, along with the collected impurities.
