Description

Collection and filtering device and washing machine Technical Field

[0001] The present invention relates to the field of cleaning equipment, and in particular to a collecting and filtering device and a washing machine. Background Art

[0002] The advantages of drum washing machines currently on the market, such as water saving, anti-entanglement, less wear and tear, and strong ability to remove stains by tumbling, are widely recognized by users. However, since there is no collection and filtering device in the drum washing machine, the lint and fabric generated by the clothes cannot be collected during the washing and rinsing process. In addition, the drum needs to use a low amount of water to achieve the tumbling effect, and the rinsing effect is not significant if the water volume is low. As a result, the cleanliness achieved by the drum washing machine is reduced, and users of drum washing need to set the washing time.

[0003] The main factors that have been missing from the design of the filter collection device of drum washing machines since they were first introduced to the market are:

[0004] 1. The tumble washing method relies primarily on the weight of the clothes contacting the inner drum wall with great force to achieve cleanliness. This contact force determines the design requirements of the inner drum wall structure to minimize wear and tear on the clothes. This makes the filter collection device more difficult to arrange than in a pulsator washing machine.

[0005] 2. Secondly, if the drum of a drum washing machine holds too much water, it will not be able to achieve the effect of beating clothes, so the water consumption must be small. Therefore, a drum washing machine cannot copy the filter collection box that uses water flow to achieve the same operation as a pulsator washing machine.

[0006] The above factors explain that the current drum washing machines on the market do not have a solution for filtering and collecting clothing scraps, lint, and pollutants;

[0007] In addition to being unable to be placed in drum washing machines, the existing market filter collection boxes also lack a collection structure in pulsator washing machines, resulting in low collection capacity. The existing market pulsator washing machine filter collection device has two collection ports, the upper collection port and the lower collection port, which limit the flow rate:

[0008] 1. Low water flow rate at the upper collection port. First, we discuss a filter collection bag type with an upper collection port. To prevent the collection port from getting caught in clothing and causing damage, the collection port is fixed inside a collection shell on the inner wall of the cylinder. As a result, the water flow must enter through extremely small holes arranged in the shell, resulting in an extremely low water flow rate.

[0009] 2. The upper collection port does not collect when the water level is low. The collection bag at the upper closing port originally relies on the undulating water flow from the impeller to generate a small amount of fluidity from top to bottom to collect the water. Therefore, the collection port cannot be limited too low. If the collection port is too low, it will not be able to utilize the fluidity of the rotating water flow and the collection port may cause overflow of the collected materials. Therefore, the collection port is designed to be located at a high position. As a result, the collection and filtration function cannot be achieved when washing clothes at medium or low water levels.

[0010] 3. The lower collection port opening wears out clothes. In order to solve the problem that the upper collection port cannot collect and filter at medium and low water levels, a filtration method with a lower collection port opening that relies on gravity to close the sealed door design structure has emerged in the market in recent years. Its main purpose is to achieve collection at upper, medium and lower water levels. However, the problem with the new structure is that the lower water inlet collection structure needs to add a sealed door structure to prevent the outflow of collected materials. The opening force of the sealed door arranged inside the shell is not enough to open it. In order to use the force of the rotating water flow of the impeller, the current design uses a sealed door, that is, the water inlet, which can only be opened directly facing the clothes. As a result, the existing lower collection filter box has the problem of excessive friction, clamping, and damage to the clothes, and there are hidden risks.

[0011] 4. There is a risk of wear and tear on clothes because the lower collection inlet opening directly faces the clothes, which will inevitably cause friction, clamping problems and damage to the clothes;

[0012] 5. Reduce Risks: Due to the limited opening, during the washing, rinsing, and drying process, there is inevitable contact and friction between the clothes and the inner drum wall, as well as the lower water inlet opening of the collection box. If the water inlet opening is too large, the probability of clothes being abraded and clamped increases, thereby increasing the risk of clothes being damaged. As a result, the size of the water inlet opening is limited. The water flow that originally relied on the circular rotation of the impeller inner drum to drive the clothes is also limited. The limited flow rate leads to poor filtration capacity.

[0013] 6. The main direction of water flow does not match the insufficient permeability. When the gravity sealing door is opened, it does not directly face the main direction of water flow, and the gravity of the gravity-closed sealing door further reduces the water entry ability facing the original weak rotation direction of the water flow containing clothes. In addition, the impeller itself forms a circular rotation of water flow, which is not completely matched with the orientation of the upper collection opening. Therefore, the orientation of the lower water inlet that does not match the fluidity setting itself causes insufficient flow rate, and the collection and filtration function is inevitably reduced. Technical issues

[0014] The above description shows that the existing drum washing machines all lack collection and filtration devices and the collection and filtration structure design of the pulsator washing machine has defects, which results in relatively low washing cleanliness of the existing washing machines. The lack of drum collection and filtration and the poor collection and filtration of the pulsator have led to the following disadvantages, which have caused adverse risks and increased costs for users:

[0015] 1. Time-consuming washing: When washing clothes, the simplest solution is to extend the washing time. As a result, users often report that drum washing takes longer than pulsator washing, which disrupts their daily lives and work.

[0016] 2. Clothing wear and tear: The time it takes to achieve satisfactory cleanliness for clothing leads to excessive wear and tear during soaking, washing, and rinsing with chemical detergents, thereby reducing the value of washing and caring for the clothing.

[0017] 3. Equipment wear and tear: Long-term washing and rinsing of clothes will cause unnecessary mechanical wear and tear on the equipment and unnecessary consumption of the electronic control system, shortening the service life of the equipment and increasing the cost of replacing parts and repair and maintenance expenses;

[0018] 4. To achieve cleanliness, users use extended washing and repeated rinsing to achieve cleanliness, which results in increased water and electricity consumption and a waste of natural resources.

[0019] 5. Using excessive amounts of chemical detergents or paying more for detergent brands not only damages clothes due to excessive chemical application, but also reduces the rinsing effect and cleaning capacity due to excessive chemical residues, repeatedly increasing the cost of using chemical detergents and increasing water resources and environmental pollution;

[0020] 6. Dirt and grime traps: The inefficient filtration of pulsator washing machines and the lack of filtration structures in front-loading washing machines result in longer wash times. This is caused by uneven and irregular structures such as the pulsator disc, tripod, lifting ribs, inner drum grille, and collection box base between the inner and outer drums. This prolongs the time that lint and contaminants remain attached, resulting in serious contamination when washing machines are disassembled and cleaned after years of use.

[0021] 7. The breeding of bacteria. Not only does the large amount of contaminants easily cause contamination during the re-washing process, but it also leads to the breeding of a large number of bacteria. This creates an unfavorable environment for the rapid spread of bacteria in public places such as hospitals, hotels, schools, dormitories, community laundries, and coin-operated laundries.

[0022] 8. Increased consumables: Pulsator washing machines have poor collection capacity, while front-loading washing machines have no collection capacity. Long-term use leads to serious accumulation of dirt and bacteria inside the washing machine. It is obvious that long-term use of washing machines has serious health risks for children, women, and the elderly. Users have begun to purchase various chemical cleaners, cleaning brushes, and disassembly tools for cleaning the washing machine drum. Due to the lack of clear information about the sanitation status of the drum and the inability to test the processing capacity and energy efficiency, frequent cleaning applications result in large financial expenses for users and chemical pollution of water resources. Do-it-yourself disassembly and cleaning consumes a lot of time and manpower, and improper disassembly and installation may cause damage to the equipment.

[0023] 9. When the lagging cleaning equipment is used well and does not need to be replaced, the inner and outer drums of the washing machine often accumulate a lot of dirt and grime, causing secondary contamination during the washing process. In addition, the growth of bacteria poses unpredictable risks to health, forcing users to pay for on-site disassembly and cleaning of the equipment. The key is that the comprehensive on-site disassembly and cleaning method fails to achieve real-time cleaning effects and health protection for users. Technical Solutions

[0051] The essence of collection and filtration is efficient collection and filtration. To achieve the function of efficient collection, strong passability is required.

This larger water inlet is also required to avoid clamping, friction, and damage to clothes. In addition to ensuring that the collection and filtration is not affected by the high, medium, and low water level limits of the pulsator washing machine, the collection structure can be fully disassembled and cleaned without the hidden dangers of dirt and grime.

[0082] The present invention provides a collection and filtration device, comprising a collection box 1, wherein the collection box 1 is provided with a fluid inlet 61 for fluid entry and a fluid outlet 62 for fluid exit, wherein the fluid outlet 62 is provided with a filter screen for filtering fabric flocs, and the interior area of ​​the collection box 1 is a filtration and collection area, wherein the fluid inlet 61 and the fluid outlet 62 are both connected to the filtration and collection area;

[0083] The fluid inlet 61 is sealed with a one-way opening sealing door 11 which is opened due to fluid impact and can be automatically closed. The one-way opening sealing door 11 is arranged inside the collection box 1. One end of the one-way opening sealing door 11 is a connecting end 52, and the other end corresponding to the one-way opening sealing door 11 is an opening end 53. The connecting end 52 of the one-way opening sealing door 11 is connected to the collection box 1 at the fluid inlet 61, and an easy-to-open structure is provided on the one-way opening sealing door 11.

[0084] In one embodiment, the easy-open structure includes an elastic reset structure provided on the connecting end 52 , and the connecting end 52 is connected to the collecting box 1 at the fluid inlet 61 via the elastic reset structure.

[0085] At least two elastic reset structures are provided.

[0086] In one embodiment, the easy-open structure includes a plurality of one-way opening sealing doors 11 that are opened by fluid impact and can be automatically closed;

[0087] Two adjacent one-way opening sealing doors 11 are sealed together. With this arrangement, when a collection and filtering device is installed in the inner drum 109 of a pulsator washing machine, the collection and filtering device is arranged along the axial direction of the inner drum 109, and the length of the collection and filtering device is adjusted as needed, so that the collection of cotton wool can be achieved even in a low water level state. For example, when the water level in the washing machine is at a low water level, the water flows through the inner drum 109 and impacts the one-way opening sealing door 11 located below the water level, thereby partially opening the fluid inlet 61 and achieving the collection of cotton wool.

[0088] In one embodiment, the fluid inlet 61 is disposed on a side surface in the width direction of the collection box 1. This arrangement allows the present invention to be installed in the inner drum 109 of a drum washing machine or a pulsator washing machine, and when the inner drum 109 rotates, the fluid inlet 61 can face the direction of water flow, thereby improving the efficiency of water entering the fluid inlet 61.

[0089] In one embodiment, the one-way opening sealing doors 11 are arranged in parallel, and the connection ends 52 of the one-way opening sealing doors 11 are respectively connected to the collection boxes 1 on one side of the fluid inlet 61.

[0090] Alternatively, the arrangement may be as follows: the connection ends 52 of the adjacent one-way opening sealing doors 11 are connected to the collection boxes 1 on both sides corresponding to the fluid inlet 61 respectively.

[0091] It can also be arranged as follows: the one-way opening sealing doors 11 are arranged in parallel, the connecting ends 52 of the one-way opening sealing doors 11 are connected to the collection box 1 through connecting pieces, and the two ends of the connecting pieces are connected to the collection boxes 1 on both sides corresponding to the fluid inlet 61.

[0092] It can also be arranged in the following manner: the one-way opening sealing doors 11 are arranged in pairs, and the connecting ends 52 of the same pair of one-way opening sealing doors 11 are respectively connected to the corresponding two sides of the fluid inlet 61.

[0093] The above setting methods can be selected according to your needs.

[0094] In one embodiment, the one-way opening sealed door 11 is rectangular, the connecting end 52 of the one-way opening sealed door 11 is the short side, and the side adjacent to the short side on the one-way opening sealed door 11 is the long side, and the length of the long side is greater than the length of the short side, so that when the water flow in the washing machine hits the one-way opening sealed door 11, the one-way opening sealed door 11 is subjected to a larger torque, thereby making it easier to open the one-way opening sealed door 11.

[0095] The elastic reset structure can be set up as follows: the elastic reset structure includes an elastic plate 31, one end of the elastic plate 31 is fixedly connected to the collection box 1 at the fluid inlet 61, and the other end of the elastic plate 31 is fixedly connected to the connecting end 52 of the one-way opening sealing door 11, and the width of the elastic plate 31 is smaller than the width of the one-way opening sealing door 11.

[0096] The elastic reset structure can also be configured as follows: the elastic reset structure includes a torsion spring, the collection box 1 at the fluid inlet 61 is connected to a rotating shaft, the upper connection end 52 of the one-way opening sealing door 11 or the upper connection end 52 of the one-way opening sealing door 11 is fixedly connected to a sleeve, the sleeve is sleeved on the rotating shaft, the torsion spring is sleeved on the rotating shaft, one protruding end of the torsion spring abuts against the collection box 1 at the fluid inlet 61, and the other protruding end of the torsion spring abuts against the one-way opening sealing door 11;

[0097] The length of the rotating shaft is smaller than the length of the connecting end 52 of the one-way opening sealing door 11 .

[0098] In one embodiment, the one-way opening sealing door 11 is provided with a groove 41 for increasing the opening force to facilitate the opening of the one-way opening sealing door 11;

[0099] The groove 41 is provided on the side of the one-way opening sealing door 11 that blocks the fluid inlet 61. When the water in the washing machine flows as the inner drum 109 rotates, the water flows into the one-way opening sealing door 11 and flows into the groove 41 on the one-way opening sealing door 11, thereby facilitating increasing the torque that pushes the one-way opening sealing door 11, making the one-way opening sealing door 11 easier to open, or increasing the opening amplitude of the one-way opening sealing door 11.

[0100] The groove 41 is provided on the side of the one-way opening sealing door 11 away from the connection collection box 1, and its purpose is also to increase the torque pushing the one-way opening sealing door 11, thereby making the one-way opening sealing door 11 easier to open, or to increase the opening range of the one-way opening sealing door 11;

[0101] The bottom of the groove 41 is recessed in a direction away from the connection end 52 of the one-way opening sealing door 11 .

[0102] The groove 41 is provided on a side of the one-way opening sealing door 11 close to the opening end 53 .

[0103] In one embodiment, a plurality of partition columns 51 are fixedly arranged at the fluid inlet 61, and the partition columns 51 and the fluid inlet 61 form a plurality of annular frames, and the central area of ​​the annular frame is a through hole for the passage of fluid. The one-way opening sealing door 11 is sealed on the annular frame and blocks the through hole. The setting of the partition columns 51 is conducive to blocking oversized debris outside the filtering and collecting area, preventing it from entering the collection box 1 and causing blockage or damage.

[0104] The collection box 1 is fixedly provided with a number of partition screens 7 equal to the number of partition columns 51. The partition screens 7 divide the internal area of ​​the collection box 1 into a number of filtration collection channels 8 equal to the number of through holes. The filtration collection channels 8 are connected to the through holes at one end close to the one-way opening sealing door 11. The filtration collection channels 8 are connected to the fluid outlet 62.

[0105] One end of the separation screen 7 is fixedly connected to the separation column 51, and the other end is fixedly connected to the filter screen arranged at the fluid outlet 62. The two side edges of the separation screen 7 are respectively fixedly connected to the collection box 1. The purpose of setting the separation screen 7 is to increase the outflow of water and further improve the collection and filtration efficiency of the woven fabric. Modes for Carrying Out the Invention

[0106] In one embodiment, the side of the collection box 1 away from the fluid outlet 62 and / or the peripheral surface of the collection box 1 adjacent to the side where the fluid inlet 61 is located are both the fluid outlet 62. That is, the fluid outlet 62 can be positioned as follows: the side of the collection box 1 away from the fluid outlet 62 is the fluid outlet 62; the fluid outlet 62 can also be positioned as follows: the peripheral surface of the collection box 1 adjacent to the side where the fluid inlet 61 is located is both the fluid outlet 62; the fluid outlet 62 can also be positioned as follows: the side of the collection box 1 away from the fluid outlet 62 and the peripheral surface of the collection box 1 adjacent to the side where the fluid inlet 61 is located are both the fluid outlet 62. This arrangement allows water entering the filtration and collection area to flow out of the fluid outlet 62 as quickly as possible, thereby improving the collection and filtration efficiency of the fabric and ensuring the permeability of the water flow.

[0107] The collection box 1 is connected to an external device via a connecting shell, which is uniformly distributed with dewatering holes. A diversion structure is provided at the fluid inlet 61, one end of which is connected to the collection box 1. This arrangement further increases the flow rate of water entering the fluid inlet 61, which helps improve the collection and filtration efficiency of the cotton wool.

[0108] When the fluid inlet 61 is arranged toward the outer cylinder, the flow guide structure can be configured as follows: the flow guide structure includes a curved plate 21, one end of which is arranged parallel to a side of the fluid inlet 61, and the other end of which is bent toward the direction of the fluid inlet 61; and two parallel side plates 23, both of which are fixedly connected to the collection box 1. The curved plate 21 is arranged in the area between the two side plates 23, and the two sides of the curved plate 21 are respectively connected to the two side plates 23 to form a flow channel, and the flow guide channel 24 is connected to the fluid inlet 61. A filter bag is provided in the collection box 1 to collect the cotton wool.

[0109] When the fluid inlet 61 is arranged toward the circumferential direction of the inner cylinder 9, the guide structure can also be arranged as follows: the guide structure is an annular guide ring plate 25, and the guide ring plate 25 is open. The opening at one end of the guide ring plate 25 is larger than the opening at the other end. The end with the smaller opening on the guide ring plate 25 is the small guide end, and the other end is the large guide end. The small guide end is fixedly connected to the collection box 1 and connected to the fluid inlet 61.

[0110] The one-way opening sealing door 11 is an elastic plate 31. The washing machine is a dual-power washing machine. The washing machine can also be a drum washing machine.

[0111] A washing machine comprises an inner drum 109 and an outer drum. The inner drum 109 is matched with a collecting and filtering device, and the collecting and filtering device is detachably connected to the inner drum 109 via a connecting shell. Industrial Applicability

[0112] When in use, a collecting and filtering device is opened from the inner drum 109 and embedded in the inner drum 109. A collecting and filtering device is detachably connected to the inner drum 109 through a connecting shell. The collection box 1 is a regular hexahedron, and the fluid inlet 61 is arranged in the circumferential direction of the inner drum 109. When the inner drum 109 rotates, the relative movement direction of the water flow in the washing machine is facing the fluid inlet 61.
