Description

Washing machine with collecting and filtering device Technical Field

[0001] The present invention relates to the field of washing machines, and in particular to a washing machine with a collecting and filtering device. 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. Technical issues

[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 flow direction of water does not match the insufficient flow capacity. When the gravity sealing door is opened, it does not directly face the main flow direction. The gravity of the gravity-closed sealing door further reduces the water inlet capacity facing the weak rotation direction of the water carrying clothes. In addition, the water flow formed by the impeller itself rotates in a circular manner, which does not fully match the orientation of the upper collection opening. Therefore, the orientation of the lower water inlet, which does not match the flow rate, is insufficient, resulting in insufficient flow rate and inevitably reduced collection and filtration functions.

[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

[0024] In order to solve the above problems, the present invention provides a washing machine with a collecting and filtering device which has a simple structure, is easy to use, can achieve efficient collection of fabric floss, and improves the cleanliness inside the washing machine.

[0043] Preferably, the washing machine is a drum washing machine, and the inner drum is provided with lifting ribs, and the lifting ribs are fixedly arranged on the collecting and filtering device.

[0044] Preferably, a collecting net bag is fixedly connected to the fluid inlet, and the collecting net bag is located in the area between the inner cylinder and the outer cylinder. Beneficial effects

[0045] The present invention opens a mounting opening on the inner cylinder and embeds the collecting and filtering device in the mounting opening. The fluid inlet is located in the area between the inner cylinder and the outer cylinder, thus avoiding the problem of low cotton wool collection efficiency caused by clothing blocking the fluid inlet.

[0048] The essence of collection and filtration is efficient collection and filtration. To achieve the function of efficient collection, strong passability is required. Therefore, increasing the water inlet and the matching water outlet is the basis for ensuring efficient filtration capabilities. Secondly, large flow rates must come from creating conditions for water flow with direct impact force. The sealing door must still be sealed and have the dual ability to be easy to open. 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.

[0049] Therefore, in the current narrow space of the inner and outer drums of the washing machine and the original weak flow rate of the washing and rinsing water, the layout can achieve efficient collection and filtration capabilities and at the same time ensure its good sealing after storage. The important core of the breakthrough point is that the structural innovation of the present invention lies in that the collection inlet is embedded between the inner and outer drums to achieve complete isolation from the clothes, completely avoiding the friction and clamping factors between the collection water inlet and the clothes, so that the enlarged opening size of the water inlet is no longer restricted. At the same time, the water inlet realizes its sealing door in the narrow space between the inner and outer drums to ensure the collection sealing capability and has the structural feature of the sealing door being easy to open, thereby increasing the water inlet flow rate, improving the passability and achieving efficient collection and filtration, and the multiple sealing doors and separation compartment structure design enhance the guarantee that high, medium and low water levels can all achieve efficient collection and filtration capabilities.

[0050] The present invention can achieve efficient filtering and collection of lint, hair scraps and pollutants in a drum washing machine, thereby filling the gap of the drum washing machine without filtering and collecting functions, improving the washing ratio of the washing machine, improving the final cleanliness of clothes, reducing washing time, reducing clothing loss, extending the service life of the washing machine, and saving water and electricity consumption.

[0077] The present invention provides a washing machine with a collecting and filtering device, comprising an inner drum 9, an outer drum 10, and a collecting and filtering device. The collecting and filtering device is provided with a fluid inlet 61 and a fluid outlet 62 for fluid outflow. The fluid outlet 62 is provided with a filter screen for filtering fabric floss. The interior area of ​​the collecting and filtering device is a filtering and collecting area, and the fluid inlet 61 and the fluid outlet 62 are both connected to the filtering and collecting area.

[0078] The collecting and filtering device is arranged on the inner tube 9, and one end of the collecting and filtering device passes through the inner tube 9 and extends into the area between the inner tube 9 and the outer tube 10. The fluid inlet 61 is located in the area between the inner tube 9 and the outer tube 10, which is conducive to not limiting the opening size of the fluid inlet and completely avoiding the risk of damage caused by contact between the fluid inlet and the clothes.

[0079] The installation position of the collecting and filtering device on the inner drum 9 of the washing machine can be: the collecting and filtering device is arranged on the circumference of the inner drum 9, or the collecting and filtering device is arranged on the bottom surface of the inner drum 9. The collecting and filtering device can also be arranged on both the circumference and the bottom surface of the inner drum 9.

[0080] In one embodiment, the fluid inlet 61 is blocked 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 provided inside the collection box 1 .

[0081] The setting direction of the collecting and filtering device on the inner drum 9 of the washing machine can be: the fluid inlet 61 is set in the circumferential direction of the inner drum 9. When the inner drum 9 of the washing machine rotates, the inner drum 9 drives the water flow in the washing machine to move. In this way, the fluid inlet 61 is facing the flow direction of the water flow, thereby increasing the water flow entering the fluid inlet 61 per unit time, which is beneficial to improving the collection and filtration efficiency. At the same time, the water flow will produce a good opening impact force on the one-way opening sealing door 11, increasing the opening amplitude of the one-way opening sealing door, thereby increasing the water flow entering the fluid inlet and ensuring good passability, thereby realizing efficient collection and filtration of fabric floss, hair cuttings and pollutants.

[0082] In one embodiment, a guide plate is provided on the fluid inlet 61 for guiding the fluid to the fluid inlet 61 , so as to increase the flow rate of the water entering the fluid inlet 61 , thereby improving the collection efficiency of the woven floss;

[0083] 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.

[0084] 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.

[0085] In one embodiment, the collecting and filtering device is connected to the inner cylinder 9 via a quick-release structure.

[0086] The collecting and filtering device is fixedly arranged on the connecting seat 72 , and the connecting seat 72 is matched and connected to the inner cylinder 9 through a quick-release structure.

[0087] The quick-release structure can adopt different structures as needed. The following is an example of a quick-release structure in the prior art: the quick-release structure includes a plurality of L-shaped locking hooks 7 fixedly arranged on the side of the connecting seat 72 facing the inner tube 9. The L-shaped locking hooks 7 are respectively located on both sides of the collection box 1. The inner tube 9 is provided with locking holes that match the L-shaped locking hooks 7. The L-shaped locking hooks 7 are matched and arranged in the locking holes.

[0088] When the connecting seat 72 is pushed along the bending direction of the L-shaped locking hook 7 , the L-shaped locking hook 7 abuts against one end of the locking hole, and the L-shaped locking hook 7 is locked with the locking hole.

[0089] The quick-release structure also includes an axial limiting device, which includes a locking plate 71 provided on one end of the connecting seat 72. A groove 41 is provided on the surface of the connecting seat 72 facing away from the L-shaped locking hook 7. The locking plate 71 is matched and arranged in the groove 41. The middle portion of the locking plate 71 is rotatably connected to the connecting seat 72 through the locking seat. One end of the locking plate 71 is connected to the connecting seat 72 by a return spring 73. The other end of the locking plate 71 is provided with a limiting shaft 74 that passes through the connecting seat 72 and extends toward the inner cylinder 9. The inner cylinder 9 is matched with an axial limiting locking hole.

[0090] When the L-shaped locking hook 7 is locked with the locking hole, the limiting shaft 74 is matched and arranged in the axial limiting locking hole;

[0091] When one end of the return spring 73 provided on the locking plate 71 is pressed, the limiting shaft 74 is disengaged from the axial limiting locking hole, so that the collecting box 1 can be quickly disassembled and assembled on the inner cylinder 9, thereby facilitating the processing of the collected and filtered cotton wool.

[0092] In one embodiment, at least two collecting and filtering devices are provided on the inner cylinder 9 , and the collecting and filtering devices are evenly distributed along the circumference of the inner cylinder 9 , thereby improving the filtering and collecting capacity and achieving efficient collection and filtration in a short time.

[0093] Each collecting and filtering device is provided with a fluid inlet 61 , and the fluid inlets 61 on two adjacent collecting and filtering devices are arranged toward each other or away from each other. Such an arrangement can improve the collection efficiency of the woven floss.

[0095] The fluid inlet 61 is provided 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 blocks the fluid inlet 61 .

[0096] In one embodiment, a plurality of one-way opening sealing doors 11 are provided; adjacent one-way opening sealing doors are sealed and connected. When fluid flows toward the fluid inlet 61 and impacts the one-way opening sealing door 11, the one-way opening sealing door 11 impacted by the fluid opens. Modes for Carrying Out the Invention

[0097] In one embodiment, the collecting box 1 is provided with fluid inlets 61 on both sides thereof. Alternatively, the collecting box 1 may be provided with fluid inlets 61 on both sides thereof staggered to improve the collection efficiency of the cotton wool.

[0098] The fluid inlet 61 is arranged on the side of the collection box 1 in the width direction. When the fluid flows toward the fluid inlet 61 and impacts the one-way opening sealing door 11, the one-way opening sealing door 11 impacted by the fluid is opened; its purpose is to face the direction of water flow in the washing machine, which is conducive to increasing the collection efficiency of textile fibers.

[0099] Several partitions 51 are fixedly mounted at the fluid inlet 61. These partitions 51 and the fluid inlet 61 form a plurality of annular frames, the central areas of which serve as passage holes for the fluid. The one-way sealing door 11 is positioned within the collection box 1, and the sealing cover is secured to the annular frames and blocks the passage holes. The partitions 51 prevent large foreign matter from entering the fluid inlet 61 while also facilitating easy opening of the one-way sealing door 11.

[0100] The collection box 1 is fixedly provided with a number of partition screens equal to the number of partition columns 51. The partition screens divide the internal area of ​​the collection box 1 into a number of filtration collection channels equal to the number of through holes. The filtration collection channels are connected to the through holes at one end close to the one-way opening sealing door 11, and are connected to the fluid outlet 62.

[0101] One end of the separation screen is fixedly connected to the separation column 51 , and the other end is fixedly connected to the filter screen provided at the fluid outlet 62 . Both sides of the separation screen are fixedly connected to the collection box 1 respectively.

[0102] One end of the one-way opening sealing door 11 is detachably connected to the annular frame through an elastic reset structure.

[0103] In one embodiment, the elastic reset structure is an elastic plate, one end of which is fixedly connected to the annular frame, and the other end of the elastic plate is fixedly connected to the one-way opening sealing door 11, and the width of the elastic plate is smaller than the width of the connected opening sealing door.

[0105] In one embodiment, a groove 41 for increasing the opening force is provided on the one-way opening sealing door 11, and the bottom of the groove 41 is recessed toward the connecting end of the one-way opening sealing door 11 or the connecting end of the one-way opening sealing plate. The purpose is also to increase the torque that pushes the one-way opening sealing door 11, thereby making the one-way opening sealing door 11 easier to open, or increasing the opening amplitude of the one-way opening sealing door 11.

[0106] The fluid outlet 62 is provided on a side of the collection box 1 away from the fluid inlet 61 and / or on a peripheral surface of the collection box 1 adjacent to the side where the fluid inlet 61 is located. Its purpose is to increase the outflow of the fluid, thereby improving the collection efficiency of the cotton wool. The one-way opening sealing door 11 is an elastic plate.

[0107] The washing machine is a drum washing machine, and the inner drum 9 is provided with lifting ribs 3, and the lifting ribs 3 are fixedly arranged on the collection box 1. Such a setting can not only ensure that the internal components of the washing machine inner drum 9 are not increased and the internal space of the washing machine inner drum 9 is not occupied, but also realize the installation of the collection and filtering device. The collection and filtering device realizes the collection of textile floss, saves space, and increases the function of collecting textile floss.

[0108] When the collecting and filtering device is set on the inner drum 9 of the pulsator washing machine, the collecting and filtering device is set along the axial direction of the inner drum 9, and the length of the collecting and filtering device is set as needed, so that the collection of textile floss 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 along the inner drum 9 and impacts the one-way opening sealing door 11 below the water level, thereby opening part of the fluid inlet 61 to achieve the collection of textile floss.

[0109] During the washing process, the water level may vary from high to medium and low. The collecting and filtering device is arranged along the axial direction of the inner cylinder 9. The collecting and filtering device is provided with a plurality of one-way opening sealing doors, so that it has the ability of efficient collection and filtering at any water level.

[0110] In one embodiment, a collection net bag is fixedly connected to the fluid inlet 61 and is located in the area between the inner drum 9 and the outer drum 10. The collection net bag is used to collect the cotton wool. The washing machine is a dual-power washing machine. The washing machine can also be a drum washing machine. Industrial Applicability

[0111] During use, the collection and filtration device is embedded into the inner drum 9 through the mounting opening 8 on the inner drum 9. The fluid inlet 61 is located in the area between the inner drum 9 and the outer drum 10. The collection box 1 is detachably connected to the inner drum 9 via 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 9. When the inner drum 9 rotates, the relative movement direction of the water flow in the washing machine is directly opposite the fluid inlet 61. Since the laundry carried by the washing machine is mixed with the water flow when the washing machine is cleaning, the water flow impacts the one-way opening sealing door 11 of the collection box 1, causing the one-way opening sealing door 11 to open, or causing the one-way opening sealing door 11 to open more widely, which helps to increase the amount of water flowing from the fluid inlet 61 into the filtration and collection area. When the water flows from the fluid inlet 61 into the filtration and collection area of ​​the collection box 1 and flows out through the fluid outlet 62, which is equipped with a filter screen to collect and filter the lint. The collection box 1 can be removed through the quick-release structure to facilitate the disposal of the collected lint, improving the cleanliness of the washing machine interior.
