Description

Technical Field

[0001] The present invention relates to the field of cleaning equipment, and particularly to a collection and filtration device and a washing machine. Background Art

[0002] The drum washing machines in the existing market have the advantages of water saving, anti-tangling, less wear, and strong ability to remove stains by tumbling, which are widely recognized by users. However, at the same time, since there is no collection and filtration device arranged in the drum washing machine, it leads to the lack of collection of lint and fabrics generated by clothes during the washing and rinsing processes. Moreover, the tumbling effect can only be achieved with a relatively low water consumption in the drum, and the rinsing effect is not significant with a low appropriate water volume. Therefore, the cleanliness achieved by the drum washing machine is reduced, and thus the washing time is set by drum washing users. The main factors for the lack of design of the filtration and collection device since the drum washing machine was launched on the market: 1. The tumbling washing method mainly relies on the large force generated by the gravity of the clothes and the inner cylinder wall to achieve cleanliness. Therefore, the contact force determines the requirements for the design structure of the inner wall of the drum. Consideration is given to avoiding wear and damage to the clothes as much as possible, making it difficult to arrange the filtration and collection device compared with the pulsator washing machine. 2. Secondly, if the water storage volume in the inner cylinder of the drum washing machine is too much, the tumbling effect on the clothes cannot be achieved. Therefore, the water consumption must be small. Thus, the drum washing machine cannot copy the filtration and collection box that uses water flow to perform operations similar to the pulsator washing machine. Based on the above factors, the solutions for the drum washing machines in the current market that have not achieved the functions of filtering, collecting, and removing lint, fabrics, and pollutants from clothes are elaborated. In addition to being unable to be arranged in the drum washing machine, the existing filtration and collection boxes in the market also have a lack of collection structure in the filtration and collection boxes arranged in the pulsator washing machine, resulting in low collection ability. The collection ports of the filtration and collection devices in the existing market pulsator washing machines are limited in flow by two types of collection ports: the upper collection port and the lower collection port. 1. Low water inlet flow rate of the upper collection port First, discuss the filtration and collection of a filtration and collection bag with an upper collection port. In order to avoid clamping the clothes at the collection port and causing damage, the collection port is fixed inside the collection shell on the inner cylinder wall. As a result, the water inlet flow rate needs to enter through extremely small holes arranged in the shell, thus resulting in a very low water inlet flow rate. 2. The upper collection port does not collect at low water levels. The collection bag with an upper closing originally relies on the slight top-down fluidity generated by the undulation of the pulsator rotating water flow to achieve collection. Therefore, the limit position of the collection port should not be too low. If the collection port is too low, it is not easy to utilize the fluidity of the rotating water flow, and if the collection port is too low, it may cause the problem of overflow of the collected substances. Therefore, the design position of the collection inlet is relatively high. As a result, the collection and filtration functions cannot be achieved during the washing of clothes at medium and low water levels. 3. Lower collection port opening wears out clothes To solve the problem that the upper collection ports cannot collect and filter at medium and low water levels, in recent years, a filtering method of collecting through the lower collection port opening with a gravity-closed sealing door design structure has emerged in the market. Its main purpose is to enable collection at upper, middle, and lower water levels. However, the problem with the new structure is that the lower water inlet collection structure needs to add a sealing door structure to avoid the outflow of collected objects. Moreover, the opening force of the sealing door cannot be realized within the shell arrangement. In order to utilize the force of the water flow rotating by the agitator, the current design applies a sealing door, that is, the water inlet can only directly face the clothes to achieve the opening ability. Therefore, all existing lower collection filter boxes have problems and potential risks of excessive friction, clamping, and damage to the clothes; 4. Directly facing the clothes causes wear Since the lower collection inlet opening directly faces the clothes, it will inevitably cause problems of friction and clamping to the clothes and the risk of damaged clothes; 5. Reducing the risk results in a limited opening During the processes of washing, rinsing, and spinning of the clothes, the clothes and the inner cylinder wall will inevitably touch and rub against the lower water inlet opening of the collection box in the same way. If the water inlet opening is too large, the probability of problems such as clothes wear and clamping will increase. To avoid an increased risk of clothes damage, the size of the designed water inlet opening is limited. Originally, the water inflow driven by the circumferential rotation of the agitator in the inner cylinder is also limited, and the limited flow rate results in low filtering ability; 6. The main water flow direction does not match and the passability is insufficient The downward-opening gravity sealing door does not directly face the main water flow direction, and the gravity of the gravity-closed sealing door further reduces the water inlet ability for the relatively weak rotating water flow carrying the clothes. In addition, the water flow formed by the agitator itself is circumferential rotation, which is not completely matched with the orientation of the upper collection opening. Therefore, the downward water inlet orientation relying on the unmatched fluidity setting results in insufficient passing flow rate, and thus the collection and filtering function will inevitably be reduced; The above elaborates on the lack of collection and filtering devices in existing drum washing machines and the design implementation defects of the collection and filtering structures of agitator washing machines, resulting in a relatively low washing cleanliness of existing washing machines. The lack of drum collection and filtering and the low collection and filtering of agitators thus lead to the following disadvantages, potential risks to users, and increased costs: 1. Time-consuming washing During the process of washing clothes, the simplest way to achieve an unsatisfactory cleaning effect is to extend the clothes washing setting time. As a result, users all report that the drum washing time is longer than that of the agitator, which causes trouble to the users' life and work; 2. Clothes wear Relying on time to achieve a satisfactory cleanliness degree for clothes leads to excessive wear of the clothes during chemical cleaner soaking, washing, and rinsing, thus reducing the realization of the value of washing and caring for clothes; 3. Equipment wear and tear: Long-term washing and rinsing of clothes with relatively long time settings cause unnecessary mechanical and physical wear to the equipment and unnecessary consumption of the electronic control system, reducing the service life of the equipment, increasing the cost of replacing accessories and maintenance; 4. Water and electricity consumption: In order to achieve the purpose of cleanliness, users apply delayed washing and use water storage for repeated rinsing to finally clean the clothes, resulting in an increase in the long-term use of water and electricity and a waste of natural resources; 5. Detergent consumption: The increased application of chemical detergents or the payment for upgrading detergent brands not only causes excessive damage to clothes due to excessive use of chemical agents, but also reduces the rinsing and cleaning effect and ability due to excessive chemical agent residues. Repeatedly increasing the payment cost of applying chemical detergents increases environmental pollution of social water resources; 6. Dirt accumulation: Due to the low filtering ability of the agitator washing machine and the lack of a filtering structure in the drum washing machine, the washing time in some cases prolongs the time for lint and pollutants to adhere to the uneven and irregular structures such as the agitator disc, tripod, lifting ribs, inner drum grille, and collection box base between the inner drum and the outer drum. Therefore, the washing machine used for many years is seriously polluted when disassembled and cleaned; 7. Bacterial growth: The large amount of attached pollutants not only easily causes pollution during the next washing process, but also leads to the growth of a large number of bacteria, providing an unfavorable environment for the rapid spread of bacteria in public scenarios such as hospitals, hotels, schools, dormitories, community laundries, and coin-operated laundries; 8. Increased consumables: The agitator washing machine has poor collection ability and the drum washing machine has no collection function. Long-term use results in serious dirt accumulation and bacterial growth inside the washing machine. Obviously, the washing machine used for many years has a serious impact on the health risks of children, women, and the elderly. Users start to buy various chemical detergents, cleaning brushes, and disassembly tools for cleaning the inner drum of the washing machine. Due to the unclear sanitary condition of the inner drum and the inability to detect the cleaning ability and energy efficiency, frequent cleaning applications result in a large financial expenditure for users, chemical pollution to water resources, and users' own disassembly and cleaning require a lot of time and manpower. Incorrect disassembly and installation may cause damage to the equipment; 9. Delayed cleaning: When the equipment is in good condition and does not need to be replaced, a large amount of dirt accumulates in the inner and outer drums of the washing machine, and secondary pollution problems often occur during the washing process. And the growth of bacteria poses an unpredictable risk to health, resulting in users having to pay for on-site disassembly and cleaning of the equipment. The key is that the all-round on-site disassembly and cleaning method fails to achieve the real-time cleanliness effect and health guarantee for users. Summary of the Invention

Detailed implementation mode

[0047] A collection and filtration device of the present invention includes a collection box 1. A fluid inlet 61 for fluid to enter and a fluid outlet 62 for fluid to flow out are provided on the collection box 1. A filter screen for filtering floccules is provided on the fluid outlet 62. The inner area of the collection box 1 is a filter collection area. The fluid inlet 61 and the fluid outlet 62 are both communicated with the filter collection area; A one-way opening and sealing door 11 that is opened by the impact of the fluid and can automatically close is pluggingly provided at the fluid inlet 61. The one-way opening and sealing door 11 is arranged inside the collection box 1. One end of the one-way opening and sealing door 11 is a connection end 52, and the other end corresponding to the one-way opening and sealing door 11 is an opening end 53. The connection end 52 of the one-way opening and sealing door 11 is connected to the collection box 1 at the fluid inlet 61. An easy-opening structure is provided on the one-way opening and sealing door 11.

[0048] In one embodiment, the easy-opening structure includes an elastic reset structure provided on the connection end 52. The connection end 52 is connected to the collection box 1 at the fluid inlet 61 through the elastic reset structure.

[0049] At least two elastic reset structures are provided.

[0050] In one embodiment, the easy-opening structure includes a plurality of one-way opening and sealing doors 11 that are opened by the impact of the fluid and can automatically close; Adjacent two one-way opening and sealing doors 11 are hermetically connected. With such a setting, when a collection and filtration device is arranged on the inner cylinder 109 of a pulsator washing machine, the collection and filtration device is arranged along the axial direction of the inner cylinder 109, and the length of the collection and filtration device is set as required, so that the collection of floccules can be realized even in the low water level state. For example, when the water level in the washing machine is at the low water level, during the flow of the water along with the inner cylinder 109, the one-way opening and sealing door 11 located below the water level line is impacted, thereby opening part of the fluid inlet 61 to realize the collection of floccules.

[0051] In one embodiment, the fluid inlet 61 is provided on the side surface in the width direction of the collection box 1. With such a setting, when the present invention is installed on the inner cylinder 109 of a drum washing machine or a pulsator washing machine, when the inner cylinder 109 rotates, the fluid inlet 61 can be aligned with the water flow direction, which is beneficial to improving the efficiency of water flow entering the fluid inlet 61.

[0052] In one embodiment, the one-way opening and closing sealing doors 11 are arranged in parallel, and the connecting ends 52 of the one-way opening and closing sealing doors 11 are respectively connected to the collection box 1 on one side of the fluid inlet 61.

[0053] It can also be set in the following way: the connecting ends 52 of adjacent one-way opening and closing sealing doors 11 are respectively connected to the collection box 1 on the two opposite sides corresponding to the fluid inlet 61.

[0054] It can also be set in the following way: the one-way opening and closing sealing doors 11 are arranged in parallel, the connecting ends 52 of the one-way opening and closing sealing doors 11 are respectively connected to the collection box 1 through connecting members, and the two ends of the connecting members are respectively connected to the collection box 1 on the two opposite sides corresponding to the fluid inlet 61.

[0055] It can also be set in the following way: the one-way opening and closing sealing doors 11 are arranged in pairs, and the connecting ends 52 of the same pair of one-way opening and closing sealing doors 11 are respectively connected to the two opposite sides corresponding to the fluid inlet 61.

[0056] The above setting methods can be selected according to needs.

[0057] In one embodiment, the one-way opening and closing sealing door 11 is rectangular, the connecting end 52 of the one-way opening and closing sealing door 11 is the short side, and one side adjacent to the short side on the one-way opening and closing sealing door 11 is the long side, and the length of the long side is greater than the length of the short side. When the water flow in the washing machine impacts the one-way opening and closing sealing door 11, the one-way opening and closing sealing door 11 receives a larger torque, so that it is easier to open the one-way opening and closing sealing door 11.

[0058] The elastic reset structure can be set in the following way: the elastic reset structures all include elastic plates 31. One end of the elastic plate 31 is fixedly connected to the collection box 1 at the fluid inlet 61, the other end of the elastic plate 31 is fixedly connected to the connecting end 52 of the one-way opening and closing sealing door 11, and the width of the elastic plate 31 is smaller than the width of the one-way opening and closing sealing door 11.

[0059] The elastic reset structure can also be set in the following way: the elastic reset structures all include torsion springs. A rotating shaft is connected to the collection box 1 at the fluid inlet 61, a sleeve is connected to the connecting end 52 of the one-way opening and closing sealing door 11 or fixedly connected to the connecting end 52 of the one-way opening and closing sealing door 11. The sleeve is sleeved on the rotating shaft, the torsion spring is sleeved on the rotating shaft, one extending end of the torsion spring abuts against the collection box 1 at the fluid inlet 61, and the other extending end of the torsion spring abuts against the one-way opening and closing sealing door 11; The length of the rotating shaft is less than the length of the connecting end 52 of the one-way opening and sealing door 11.

[0060] In one embodiment, a groove 41 for increasing the opening force to facilitate the opening of the one-way opening and sealing door 11 is provided on the one-way opening and sealing door 11; The groove 41 is provided on the surface of the one-way opening and sealing door 11 that blocks the fluid inlet 61. When the water flow in the washing machine flows as the inner cylinder 109 rotates, the water flow impacts the one-way opening and sealing door 11 and flows into the groove 41 on the one-way opening and sealing door 11, which is beneficial to increasing the torque for pushing the one-way opening and sealing door 11, making the one-way opening and sealing door 11 easier to open, or increasing the opening amplitude of the one-way opening and sealing door 11.

[0061] The groove 41 is provided on the side of the one-way opening and sealing door 11 away from the connection with the collection box 1, and its purpose is also to increase the torque for pushing the one-way opening and sealing door 11, so that the one-way opening and sealing door 11 is easier to open, or increasing the opening amplitude of the one-way opening and sealing door 11; The bottom of the groove 41 is recessed in the direction away from the connecting end 52 of the one-way opening and sealing door 11.

[0062] The groove 41 is provided on the side of the one-way opening and sealing door 11 close to the opening end 53.

[0063] In one embodiment, a plurality of partition columns 51 are fixedly provided at the fluid inlet 61. The partition columns 51 and the fluid inlet 61 form a plurality of annular frames. The central area of the annular frame is a through hole for fluid passage. The one-way opening and sealing door 11 is hermetically covered on the annular frame and blocks the through hole. The arrangement of the partition columns 51 is beneficial to blocking oversized sundries outside the filtering and collecting area and preventing them from entering the collection box 1 and causing blockage or damage.

[0064] A partition sieve 7 with the same number as the partition columns 51 is fixedly provided inside the collection box 1. The partition sieve 7 divides the internal area of the collection box 1 into filtering and collecting channels 8 with the same number as the through holes. One end of the filtering and collecting channel 8 close to the one-way opening and sealing door 11 is connected to the through hole, and the filtering and collecting channel 8 is connected to the fluid outlet 62; One end of the partition sieve 7 is fixedly connected to the partition column 51, and the other end is fixedly connected to the filter net provided at the fluid outlet 62. The two sides of the partition sieve 7 are respectively fixedly connected to the collection box 1. The purpose of the partition sieve 7 is to increase the water flow out volume and further improve the collection and filtration efficiency of the lint.

[0065] 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 that is adjacent to the side where the fluid inlet 61 is located are both fluid outlets 62. That is, the position of the fluid outlet 62 can be set as follows: the side of the collection box 1 away from the fluid outlet 62 is the fluid outlet 62; the position of the fluid outlet 62 can also be set as follows: the peripheral surface of the collection box 1 that is adjacent to the side where the fluid inlet 61 is located is the fluid outlet 62; the position of the fluid outlet 62 can further be set as follows: the side of the collection box 1 away from the fluid outlet 62 and the peripheral surface of the collection box 1 that is adjacent to the side where the fluid inlet 61 is located are both fluid outlets 62. Such a setting enables the water flow entering the filtration collection area to flow out from the fluid outlet 62 as quickly as possible, which is beneficial to improving the collection and filtration efficiency of the flocculent material and ensuring the water flow passability.

[0066] The collection box 1 is connected to an external device through a connection housing, and dehydration holes are evenly distributed on the connection housing. A diversion structure is provided at the fluid inlet 61, and one end of the diversion structure is connected to the collection box 1; with such a setting, the flow rate of the water flow entering the fluid inlet 61 is further increased, which is beneficial to improving the collection and filtration efficiency of the flocculent material; When the fluid inlet 61 faces the outer cylinder, the diversion structure can be set as follows: the diversion structure includes an arc-shaped plate 21, one end of the arc-shaped plate 21 is arranged parallel to one side edge of the fluid inlet 61, and the other end of the arc-shaped plate 21 is bent towards the direction of the fluid inlet 61; it also includes two parallel side plates 23, both of the two side plates 23 are fixedly connected to the collection box 1, the arc-shaped plate 21 is arranged in the area between the two side plates 23, and both sides of the arc-shaped plate 21 are respectively connected to the two side plates 23 to form a diversion channel, and the diversion channel 24 is connected to the fluid inlet 61. A filter bag is arranged in the collection box 1 to realize the collection of the flocculent material.

[0067] When the fluid inlet 61 faces the circumferential direction of the inner cylinder 9, the diversion structure can also be set as follows: the diversion structure is an annular diversion ring plate 25, the diversion ring plate 25 is provided with an open end, the opening at one end of the diversion ring plate 25 is larger than the opening at the other end, the end with the smaller opening on the diversion ring plate 25 is the diversion small end, and the other end is the diversion large end, and the diversion small end is fixedly connected to the collection box 1 and is connected to the fluid inlet 61.

[0068] The one-way opening and sealing door 11 is an elastic plate 31. The washing machine is a double-power washing machine. The washing machine can also be a drum washing machine.

[0069] A washing machine includes an inner cylinder 109 and an outer cylinder, and the above-mentioned collection and filtration device is matched and arranged on the inner cylinder 109, and the collection and filtration device is detachably connected to the inner cylinder 109 through a connection housing.

[0070] In use, a collection and filtration device is opened from the upper opening of the inner cylinder 109 and is embedded in the inner cylinder 109. A collection and filtration device is detachably connected to the inner cylinder 109 through a connecting housing. The collection box 1 is a regular hexahedron, and the fluid inlet 61 is arranged in the circumferential direction of the inner cylinder 109. When the inner cylinder 109 rotates, the relative movement direction of the water flow in the washing machine is directly opposite to the fluid inlet 61. Since when the washing machine cleans clothes, the lint carried on the clothes is mixed in the water flow. When the inner cylinder 109 rotates, the water flow impacts the one-way opening and sealing door 11 on the collection box 1. Under the action of the easy-opening structure, the one-way opening and sealing door 11 is easier to open, or the opening amplitude of the one-way opening and sealing door 11 is larger, which is beneficial to increasing the water flow rate entering the filtration and collection area from the fluid inlet 61. When the water flow enters the filtration and collection area of the collection box 1 from the fluid inlet 61 and flows out from the fluid outlet 62, a filter screen is arranged at the fluid outlet 62 to achieve the collection and filtration of lint.
