Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and in particular relates to a filter assembly of a washing machine and the washing machine. Background Art

[0002] The rapid development of technologies related to laundry treatment equipment has brought great convenience to users. Most families need to purchase multiple laundry treatment equipment. At this time, the user's recognition of laundry treatment equipment directly determines the user's purchase target for replacement laundry treatment equipment.

[0003] Currently, there are many types of lint filters used in washing machines. These typically utilize left and right baffles or the agitation of a pulsator to force water upward through the bottom of the filter cover, with a stopper preventing backflow. This structure struggles to prevent backflow and also carries away some of the filtered lint, resulting in poor lint filtration performance.

[0004] Chinese patent application number 201710104107.4 discloses a magic lint filter structure for a fully automatic washing machine, including a structural body, which includes an outer barrel, an inner barrel, and a pulsator above the inner barrel. Drainage grids are provided around the bottom of the inner barrel, through holes are opened on the pulsator, and reinforcing ribs are provided on the back of the pulsator.

[0005] The above-mentioned lint filtering structure still uses the traditional method of water flowing in from the top of the filtering structure and out from the bottom for filtering. However, the filtered lint easily flows back into the washing tub again with the water flow, affecting the filtering effect. In addition, this structure cannot be disassembled, which makes it inconvenient to clean.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a filter assembly for a washing machine and a washing machine. When the impeller agitates and washes, a vacuum is formed between the bottom of the impeller and the washing tub. The washing water flows into the filter unidirectionally through the water-stop baffle for filtration, cleaning up impurities such as lint. The clean washing water flows into the washing tub through the leakage hole, realizing the filtration circulation of the washing water and avoiding the backflow of the washing water, thereby improving the filtration effect of the filter assembly and thus improving the filtration efficiency.

Therefore, they cannot be understood as limiting the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary.

[0037] Currently, lint filters in washing machines typically use left and right baffles, or utilize the agitation of a pulsator to force water upward through the bottom of the filter cover, with a stopper preventing backflow to collect lint. This structure struggles to prevent backflow and also carries away some of the filtered lint, resulting in poor lint filtration performance.

[0038] Example 1

[0039] To solve the above problems, Figures 1 to 4 As shown, this embodiment provides a filter assembly 1 for a washing machine, the washing machine including a pulsator 2 and a washing tub, including:

[0040] The filter is arranged in the middle area of ​​the impeller 2 and has a water-stopping baffle 11 inside for one-way water inlet;

[0041] The impeller 2 is provided with a water leakage hole 21 at a position corresponding to the bottom of the filter;

[0042] When the pulsator 2 rotates, a vacuum is formed between the pulsator 2 and the bottom of the washing tub, and external water flows through the water-stopping baffle 11 to the inside of the filter for filtration, and then flows into the washing tub from the water leakage hole 21.

[0043] In the above scheme, the washing machine includes a pulsator 2 and a washing tub. The washing tub is used to place clothes to be washed, and the pulsator 2 is used to agitate and wash the clothes. The bottom of the pulsator 2 is connected to the inside of the washing tub, and the washing water flows into the washing tub through the bottom of the pulsator 2 to wash the clothes.

[0044] In this embodiment, the washing machine further includes a filter assembly 1 , which is installed in the washing tub and on the pulsator 2 .

[0045] Specifically, the pulsator 2 stirs and washes the clothes, and the lint and impurities in the clothes flow into the filter assembly 1 along with the washing water. The filtered washing water flows from the bottom of the pulsator 2 into the washing tub, thereby filtering the lint and other impurities in the washing water.

[0046] Furthermore, the filter assembly 1 includes a filter, which is arranged in the middle area of ​​the impeller 2, that is, the filter is installed in the middle area of ​​the bottom of the washing tub, so that when the laundry rotates with the impeller 2, the washing water can flow into the inside of the filter due to its own inertia for filtration, filtering out the lint in the washing water, thereby improving the washing effect of the clothes.

[0047] Furthermore, a water-stopping baffle 11 is provided in the filter, and the water-stopping baffle 11 can realize the function of one-way water inflow.

[0048] Specifically, when the washing water flows toward the filter, it can enter the interior thereof unidirectionally from the water stop baffle 11 to achieve filtration of the washing water. At the same time, the water stop baffle 11 can prevent the washing water from flowing out in the reverse direction, thereby preventing the lint in the washing water from flowing into the washing tub again, achieving an anti-backflow function, and helping to improve the filtering effect.

[0049] In this embodiment, the water stop baffle 11 is made of a flexible elastic material and can be deformed toward the inside of the filter so that washing water can only enter from above the filter, while washing water flowing back from below is blocked by the water stop baffle 11.

[0050] In this embodiment, a water leakage hole 21 is further provided on the impeller 2. The water leakage hole 21 is set at a position corresponding to the impeller 2 and below the filter. After the washing water is filtered by the filter, it flows to the bottom of the impeller 2 through the water leakage hole 21 and then flows into the washing tub, realizing the filtering circulation process of the washing water.

[0051] In this embodiment, a plurality of leakage holes 21 are provided at the center position of the impeller 2, and no leakage holes 21 are provided at other positions of the impeller 2 and at the overlapping portion of the bottom of the washing tub and the impeller 2, so that the washing water can only enter the bottom of the impeller 2 from the above-mentioned leakage holes 21.

[0052] In the specific implementation process, when the impeller 2 rotates, a vacuum is formed between the impeller 2 and the bottom of the washing tub, which accelerates the flow of water in the washing tub to the filter, filtering out impurities such as lint. At the same time, the water stop baffle 11 can prevent the washing water from flowing back, and then the clean washing water flows to the bottom of the impeller 2 through the leakage hole 21, and finally flows into the washing tub, thereby filtering the washing water and preventing the backflow of the washing water, improving the filtering effect of the filter component 1, and further enhancing the user experience.

[0053] In a further solution of this embodiment, the filter further includes a filter screen 12 , and the filter screen 12 is disposed inside the filter.

[0054] Specifically, the filter 12 is embedded under the water-stop baffle 11. When the washing water flows into the filter through the water-stop baffle 11, the filter 12 filters impurities such as lint in the washing water, thereby filtering the washing water and improving the washing effect of the clothes.

[0055] In this embodiment, the filter screen 12 may also adopt a filter box structure, which can be adaptively adjusted according to specific usage requirements.

[0056] In this embodiment, the drain holes 21 on the impeller 2 are only provided in the middle area corresponding to the area below the impeller 2 and the filter, and no drain holes 21 are provided at other locations on the impeller 2. The bottom of the washing tub is also provided with multiple drain holes 21 around its perimeter. These drain holes 21 are provided at positions corresponding to the area below the impeller 2, and no drain holes 21 are provided at other locations on the bottom of the washing tub. This is to facilitate drainage of the washing tub. Furthermore, when the impeller 2 rotates, a vacuum is formed between the impeller 2 and the washing tub, facilitating the flow of wash water into the filter and improving filtration efficiency.

[0057] Example 2

[0058] This embodiment is a further description of the above embodiment 1.

[0059] like Figures 2 to 3As shown, in this embodiment, the filter further includes an upper cover 13 , which is installed on the top of the filter and is arranged above the water stop baffle 11 .

[0060] Furthermore, the upper cover 13 includes a water inlet 131, which is provided on the surface of the upper cover 13. Washing water flows into the interior of the filter through the water inlet 131, and then flows into the filter screen 12 through the water stop baffle 11, completing the above-mentioned filtering step.

[0061] In this embodiment, the surface of the upper cover 13 is provided with a plurality of water inlet holes 131 for increasing the water inlet speed of the filter and improving the filtration efficiency. The shape, size and number of the water inlet holes 131 can be adaptively adjusted according to specific usage requirements.

[0062] Furthermore, the upper cover 13 further includes a boss 132 , which is disposed on the surface of the upper cover 13 and on one side of the water inlet 131 .

[0063] Specifically, the boss 132 protrudes from one side of the upper cover 13 toward the direction away from the pulsator 2 for a certain length. That is, the height of the boss 132 is higher than the height of the water inlet 131. When the pulsator 2 agitates and washes clothes, the boss 132 can contact and support the clothes, preventing the clothes from approaching the upper cover 13 and blocking the water inlet 131, thereby ensuring the filtration of the wash water. Furthermore, the boss 132 can rub against the clothes, which helps to improve the washing effect.

[0064] In this embodiment, the filter further includes a mesh bag bracket 15 , and the mesh bag bracket 15 is embedded in the filter.

[0065] Specifically, the mesh bag holder 15 is clamped in the filter, and the edge of the filter 12 is fixedly connected to the top of the mesh bag holder 15 to achieve fixed installation of the filter 12. The mesh bag holder 15 is detachably connected to the inner wall of the filter, which is convenient for users to disassemble and clean, and prevents the filter 12 from accumulating lint.

[0066] Furthermore, the filter further comprises a positioning piece 14, which is mounted above the mesh bag support 15 and is mounted horizontally. The water stopper 11 is disposed on the positioning piece 14 to achieve fixed installation of the water stopper 11.

[0067] In this embodiment, the filter further includes a support frame 16 , and the support frame 16 is disposed in the middle area of ​​the impeller 2 .

[0068] Specifically, the mesh bag bracket 15 is clamped in the support frame 16, the filter net 12 is installed on the mesh bag bracket 15, the positioning piece 14 is arranged above the mesh bag bracket 15, the water stop baffle 11 is installed on the positioning piece 14, and the upper cover 13 covers the support frame 16 to realize the combined installation of the filter.

[0069] Furthermore, a latching protrusion is provided at the bottom of the support frame 16 , and the latching protrusion extends from the bottom of the support frame 16 toward one side of the impeller 2 . The support frame 16 is fixedly mounted on the impeller 2 via the latching protrusion, thereby fixing the filter and the impeller 2 .

[0070] Example 3

[0071] This embodiment is a further description of the above embodiments 1 and 2.

[0072] like Figures 3 and 4 As shown, in this embodiment, the filter further includes a rotating portion 17 .

[0073] Specifically, the rotating part 17 is arranged at the connection between the upper cover 13 and the support frame 16. One end of the rotating part 17 is connected to the upper cover 13, and the other end is connected to the support frame 16. The upper cover 13 can rotate around one side of the support frame 16 to open the filter for cleaning, thereby ensuring the filtering effect of the filter.

[0074] Furthermore, the rotating part 17 includes a first pin shaft 171, a torsion spring 172 and a first hand buckle 173. The torsion spring 172 is sleeved on the first pin shaft 171 and fixedly connected to the first hand buckle 173. One end of the first hand buckle 173 is installed on the edge of the upper cover 13, and the other end is clamped with the outer periphery of the support frame 16.

[0075] Specifically, the rotating portion 17 is disposed on one side of the support frame 16. A first handle 173 of the rotating portion 17 is mounted on the support frame 16 and connected to the upper cover 13. The first pin 171 is disposed within the first handle 173, and the torsion spring 172 is sleeved on the first pin 171. When a user presses the first handle 173 with a finger, the lock between the upper cover 13 and the support frame 16 by the first handle 173 is released, allowing the upper cover 13 to rotate about the fixed position where the upper cover 13 and the support frame 16 are pivotally connected, thereby opening the filter, cleaning the interior, and removing accumulated lint.

[0076] like Figure 5 As shown, in another solution of this embodiment, the rotating portion 17 further includes a claw 174 , a second pin 175 , a second hand buckle 176 and a third pin 177 .

[0077] Specifically, the claw 174 is mounted on the support frame 16, with one end rotatably connected to the upper cover 13 and the other end fixed to one side of the support frame 16. A second pin 175 is disposed within the claw 174. The second hand buckle 176 is disposed on the other side of the support frame 16, opposite the claw 174. One end of the second hand buckle 176 is connected to the upper cover 13 and the other end is movably connected to the support frame 16 via a third pin 177.

[0078] In the specific implementation process, the user manually presses the second hand buckle 176 to release the lock between the upper cover 13 and the support frame 16, so that the upper cover 13 can rotate around the second pin shaft 175, thereby opening the filter and clearing impurities such as wire scraps inside it.

[0079] In this embodiment, the claw 174 is configured to be half-moon shaped and is fixedly engaged with the second pin 175, thereby facilitating the disassembly of the card box. The structure of the claw 174 can be adaptively adjusted according to the specific rotation connection form.

[0080] The claw 174 is arranged on one side of the support frame 16, one end of which is rotatably connected to the upper cover 13, and the other end is fixed to the support frame 16 through the second pin shaft 175; the second hand buckle 176 is arranged on the other side of the support frame 16, one end of which is fixed to the upper cover 13, and the other end is movably connected to the support frame 16 through the third pin shaft 177.

[0084] In this embodiment, the pulsator 2 of the washing machine is provided with a plurality of water-repelling ribs 22. Specifically, when the water-repelling ribs 22 rotate, the bottom of the pulsator 2 communicates with the interior of the washing tub, creating a vacuum. External water flows through the filter assembly 1 to the bottom of the pulsator 2 for filtration, and then flows from the bottom of the pulsator 2 to the interior of the washing tub, completing the washing water filtration process.
