Description

Technical Field

[0001] This utility model relates to the field of foreign matter separation and filtration devices, specifically to a collection and filtration device and a washing machine. Background Technology

[0002] Drum washing machines are gradually becoming the mainstream choice for families due to their advantages of water saving, preventing clothes from tangling, and tumbling during washing. However, due to the lack of a separate collection and filtration function in their structural design, lint and particulate pollutants from the washed and rinsed fabrics cannot be completely removed, resulting in poor overall cleaning performance compared to top-loading washing machines. Furthermore, the dirt that accumulates inside the washing machine drum over a long period of time has become a problem that the industry is currently trying to solve. At the same time, the bacteria generated have endangered human health. As a result, a large number of third-party and manufacturer-operated disassembly and cleaning services for washing machines have emerged in the current market.

[0003] Meanwhile, the existing pulsator washing machine has structural design drawbacks: it relies on a bottom motor to drive the pulsator to rotate forward and backward to wash water. Since the water force is transmitted spirally upward from bottom to top, the torque is not equal at different water levels. This causes clothes to tangle in different water level ranges. In addition, the forward and reverse rotation causes serious tangling problems. As a result, the large torque generated during the washing process often causes varying degrees of damage to the clothes. Due to these drawbacks, most users are gradually inclined to choose the existing front-loading washing machine on the market.

[0004] Currently available drum washing machines do not have a filter collection structure design, resulting in various drawbacks:

[0005] The dirt was not separated. The drum washing process uses tumbling to quickly separate the contaminants from the clothes, but it was not separated in time during the pre-wash and washing programs. The lint and contaminants in the fabric were always present in the clothes during the washing process. This is obviously far from the separation and collection effect of the filter box designed inside the drum of the impeller during the washing process.

[0006] The rinsing process is not very effective. Compared to the filter box or filter screen of a top-loading washing machine, the rinsing program of a drum washing machine is basically ineffective for cleaning lint and particulate contaminants. The drum rinsing program only cleans clothes with highly fluid substances such as laundry detergent or washing powder. The drum rinsing program has no value in separating and collecting lint and particulate contaminants from clothes.

[0007] The accumulation of dirt and grime is commonplace. Due to the lack of a separation and collection structure in the drum, the gaps inside the drum, the rear transmission metal frame and corners, as well as the drum wall, have become breeding grounds for dirt. Numerous videos of disassembling and washing drum washing machines and information published on brand websites indicate that "the total bacterial count of household drum washing machines exceeds the standard in 81.3%, the total coliform count is 100%, and the mold count is 61.2%. During washing, mold and bacteria are easily carried into the water, causing skin problems." The inner drum of a drum washing machine has essentially become a large "dirt collection box."

[0008] Existing cleaning methods are cumbersome and expensive. Due to some users experiencing their drums becoming dirtier after washing, a large number of third-party drum cleaning services have emerged in the market. Manufacturers have launched various solutions to address the shortcomings of existing drums.

[0009] Hot water washing is one of the first features introduced by various brands of washing machines: "drum self-cleaning function". This means that when the washing machine is empty, water is added and heated to 80-90 degrees Celsius and the drum rotates on its own. It is recommended to perform a hot water wash once a month.

[0010] Purchase descaling agent. Secondly, major brands offer professional descaling agents (60 degrees) and cleaning agents (90 degrees) at different water temperatures for deep cleaning of the drum every 3 to 6 months. They advertise the removal of odors and the extension of machine lifespan, which also proves that the severity of the dirt has already damaged the machine, resulting in high maintenance costs for users in the long term.

[0011] On-site disassembly and cleaning services for drum washing machines have led to a surge in third-party disassembly and cleaning services for drum washing machines, with numerous disassembly videos realistically and completely demonstrating the severity of dirt accumulation in drum washing machines of various brands. International brand manufacturers have also recently announced the launch of several standard-priced services, including professional on-site cleaning and deep disassembly by engineers, ranging from 400 to 500 yuan. Design flaws have resulted in cumbersome maintenance in the later stages.

[0012] The current situation and solutions reveal the problems and severity of the non-separate collection and filtration design of drum washing machines. At the same time, the above three solutions are all outdated solutions and have not solved the original purpose of washing and cleaning clothes, nor have they addressed the issue of pollution during the washing process.

[0013] The structural design is challenging, and the aforementioned problems have not yet been resolved immediately. This is mainly because the drum tumbling structure involves close contact between the clothes and the drum wall, and the machine's design premise is to ensure that the clothes are not damaged. All contact surfaces inside the drum should be kept as smooth as possible. Therefore, the structural design of the drum's built-in filter device to separate and collect the clothes while ensuring that the contaminants do not leak during the forward and reverse rotation of the inner drum during the washing process is very difficult. Utility Model Content

[0031] When the opening pin is pressed to connect to the housing, the opening head on the opening pin moves toward the locking plate and pushes the locking limit pin out of the locking hole.

[0032] Preferably, one end of the opening pin is fixedly connected to the housing via an elastic reset device. The elastic reset device includes a pressing seat, an opening bracket, and a reset spring. The opening bracket is provided with a guide hole to guide the opening pin toward or away from the locking plate.

[0033] The diameter of the pressing seat is larger than the diameter of the opening pin, and the reset spring is sleeved on the opening pin between the opening bracket and the pressing seat.

[0034] When the housing containing the pressing base is pressed, the reset spring is compressed and deformed, the opening pin extends out from the guide hole and pushes the opening head toward the wedge block on the locking plate, moving away from the axial limit locking hole.

[0035] Preferably, the shell is elongated and includes a first side wall and a second side wall arranged in a figure-eight shape. The first side wall and the second side wall are fixedly connected by an arc-shaped connecting plate to form an arched top plate.

[0046] This invention has a simple structure. Fabric lint and particulate pollutants enter the housing through a medium inlet connected to the inside of the housing, and then enter the collection filter bag through a collection inlet, thereby achieving the filtration and collection of fabric lint and particulate pollutants. By setting a mesh bag binding structure, this invention ensures that when the collection and filtration device rotates with the external equipment, the fabric lint and particulate pollutants entering the collection filter bag cannot flow out from the collection inlet, thus ensuring the reliability of the collection of fabric lint and particulate pollutants.

[0047] This utility model discloses a drum washing machine, in which the medium inlet is located on the inner drum, and the shell is covered on the medium inlet and detachably fixed to the inner drum.

Fabric lint and particulate pollutants enter the shell with the water flow. The plane of the collection inlet on the filter collection frame is parallel to the plane of the rotation axis of the inner drum. During the operation of the drum washing machine, the collection filter screen filters and collects fabric lint and particulate pollutants. The collection inlets in two adjacent lifting ribs are arranged in the same direction or opposite directions, which greatly improves the filtration and collection of fabric lint and particulate pollutants by the collection filtration device. The collection filter screen bag has a large water flow rate and has a good filtration effect.

[0049] This utility model discloses a pulsator washing machine that utilizes two or more vertically arranged collection and filtration devices on the inner wall of the drum. The inner drum is rotated by a motor, causing the collection and filtration devices to generate equal torque on the water inside the drum in both directions. Because the torque generated by the collection and filtration devices on the water in the upper and lower water levels is equal, it is less likely to cause excessive tangling of the placed clothes, thus effectively avoiding pulling damage caused by torque. This novel design has a unique anti-tangling effect, making washing more comprehensive, spin-drying cleaner, and drying more convenient.

[0050] This invention effectively improves the cleanliness of the drum, reduces dirt and grime buildup, lowers bacterial growth and harm to human skin, minimizes the cost to users due to disassembly and cleaning and the use of various chemical cleaning agents, and effectively extends the service life of the washing machine.

[0128] The angle at which the filter collection frame 1 swings around the axis of rotation is less than 90 degrees.

[0129] During use, the inner drum 17 rotates to wash the clothes. During this process, water flows into the housing 19 through the medium inlet 18 and into the collection filter bag 2 through the collection inlet 22. The collection filter bag 2 collects the fabric lint and particulate pollutants mixed in the water flow. The water that has been filtered by the collection filter bag 2 flows out through the medium outlet 20 on the housing 19.

[0130] The following is an example of how to use a front-loading washing machine:

[0131] In use, a collection and filtration device is installed on the inner drum 17 of the drum washing machine as required. The media inlet 18 is either located on the inner drum 17 or on the housing 19 of the collection and filtration device, depending on the need. When the washing machine is working, the collection and filtration device, as part of the lifting ribs, lifts and tumbles the clothes to achieve washing. During washing or rinsing, water flows into the housing 19 through the media inlet 18. Fabric lint and particulate contaminants mixed in the water flow enter the housing 19 through the media inlet 18 and then enter the collection filter bag 2 through the collection inlet 22. The fabric lint and particulate contaminants are filtered and collected by the collection filter bag 2, and the water flows out of the housing... The medium flows out of the outlet 20 on body 19. During the reciprocating rotation of inner cylinder 17, the collection filter bag 2 is in an open state under the action of centrifugal force, so that fabric lint and particulate pollutants can enter the bottom of the collection filter bag 2. At the same time, during the reciprocating rotation of inner cylinder 17, when the collection filter bag 2 is above the horizontal plane passing through the rotation axis of inner cylinder 17, since the end of the collection filter bag 2 away from the filter collection frame 1 passes through the two binding posts 3, the end of the collection filter bag 2 away from the filter collection frame 1 is in a vertical downward state under the action of gravity. This reduces the cross-sectional area of ​​the bag channel located at the binding post 3 of the collection filter bag 2, and may even reduce the distance between the bottom of the collection filter bag 2 and the collection inlet 22. The inner cylinder 17 is not connected to the inner cylinder 17, thus preventing lint and particulate pollutants entering the filter bag 2 from flowing out of the collection inlet 22. When the inner cylinder 17 rotates clockwise or counterclockwise, regardless of whether adjacent collection inlets 22 are facing each other or in the same direction, it ensures that lint and particulate pollutants cannot flow out of the collection inlet 22. This is because when the collection inlet 22 of the filter bag 2 is in the same direction as the rotation of the inner cylinder 17, water flows into the filter bag 2 from the collection inlet 22 and flows out from the tail of the filter bag 2, keeping the lint and particulate pollutants at the tail of the filter bag 2. When the collection inlet 22 of the filter bag 2 is in the same direction as the rotation of the inner cylinder 17, water flows into the filter bag 2 from the collection inlet 22 and flows out from the tail of the filter bag 2, keeping the lint and particulate pollutants at the tail of the filter bag 2. When reversed, the inner cylinder 17 rotates, and the tail of the collection filter bag 2, under the reaction force of the water flow, bends around the binding column 3 and reaches one side of the collection inlet 22, so that the area inside the tail of the collection filter bag 2 is not connected to the collection inlet 22. That is, the binding column 3 divides the collection filter bag 2 into two areas: a first area connected to the collection inlet 22 and a second area for storing lint and particulate pollutants. The first area can collect lint and particulate pollutants. When the inner cylinder 17 reverses, the first area and the second area are connected. The lint and particulate pollutants that entered the first area enter the second area, thus collecting the lint and particulate pollutants and continuing the next cycle.

[0132] The installation and disassembly process of the collection and filtration device of this utility model on a drum washing machine is as follows:

[0133] When installing a collection and filtration device, the L-shaped locking hooks 5 on the limiting plates 4 on both sides of the housing 19 are aligned with the locking holes on the inner cylinder and inserted into the locking holes. Then, the housing 19 is pushed along its length, and the L-shaped locking hooks 5 on the limiting plates 4 are respectively engaged with the matching locking holes on the inner cylinder 17. At this time, the axial locking limiting pins 7 on the locking plate 6 are engaged with the axial limiting locking holes set at the corresponding positions on the inner cylinder 17, thus completing the fixed connection between the housing 19 and the inner cylinder 17. When it is necessary to remove the housing 19 and take out the collection and filtration bag 2, the operator holds the housing 19 and presses the pressing seat set on the housing 19. At position 11, the distance between the two side walls of the housing 19 decreases. At this time, the opening head 10 on the opening pin 12 moves toward the locking plate 6. When the wedge-shaped opening head 10 extends into the area between the inner cylinder 17 and the wedge block 9, the opening head 10 drives the axial locking limit pin 7 to move away from the inner cylinder from the axial locking hole. The opening head 10 continues to move until the axial locking limit pin 7 is completely disengaged from the axial locking hole. Then, the housing 19 is pulled in the opposite direction, and the L-shaped locking hook 5 is disengaged from the locking hole. Then, the housing 19 is moved away from the inner cylinder, completing the disassembly of the collection and filtration device and the inner cylinder 17.

[0134] The filter bag has a folded shape on both sides. When the roller rotates to the water level, the water flow causes the mesh to open, resulting in a large water intake. After rotating out of the water surface, it forms an inward force to prevent pollutants from flowing out due to the direction of the rotation and reverse flow.

[0135] The significant value of this invention lies in its ability to provide existing household users with drum washing machines with multiple options for achieving separate collection and filtration functions, improving the cleanliness of clothes, preventing dirt and bacteria from accumulating, reducing the cost of modification and use, and requiring only the replacement of the currently used lifting rib components. Of course, the preferred option is to replace the inner drum with a grooved water inlet structure for a cleaner and healthier result.

[0136] For the current market, the realization of the separation and filtration function in drum washing machines is a significant breakthrough in the laundry industry. As a result, drum washing machines no longer suffer from poor cleanliness due to the inability to separate and filter the filter, while effectively improving the cleanliness inside the drum, reducing dirt and grime buildup, lowering bacterial growth and harm to human skin, minimizing the cost to users due to disassembly and cleaning, and using various chemical cleaning agents, and effectively extending the service life of the washing machine.

[0137] This utility model provides a collection and filtration device that, while fulfilling the existing lifting rib function, also achieves the collection and filtration function. This parallel functional design avoids the problem of excessive wear and tear on clothes caused by too many functional components inside the inner drum during the washing and tumbling process of a drum washing machine.

[0138] In this utility model, the lifting ribs and the collection filter bag in the collection and filtration device can be disassembled and cleaned simultaneously.
