Problems solved by technology

However, because the wave wheel rotates to drive the water flow to rotate, the water flow entering the cavity directly hitting the vertical rib will cause a sharp backflow of the water flow, and a part of the water flow will flow out after being filtered by the filter device of the filter cavity. It is too late to close, so part of the water flow will form a vortex in the cavity and flow out from the side water inlet, or directly rebound and flow out from the side water inlet, and at the same time, a part of the lint will be washed out, so that the collection rate of the lint is not high.
[0004] Therefore, the lint filtering method of the existing washing machine lint filtering device is single, and cannot achieve a good effect of lint filtering and collection.

Embodiment 1

[0066] like image 3 As shown, the difference between this embodiment and the above-mentioned specific implementation is that a backflow prevention structure 205 is arranged on the inner wall of the filter back cover 206 , and the backflow prevention structure 205 is arranged at the lower part of the first water inlet 204 .

[0067] In order to achieve the effect of preventing the backflow of lint by the anti-return structure, and at the same time not to affect the washing water entering the inner cavity of the lint filter for filtering, the anti-return structure 205 is used when the front cover 203 of the filter and the rear cover 206 of the filter are closed. There is a certain distance from the inner wall of the filter front cover 203 . The height of the backflow prevention structure 205 is 1 / 10-1 / 2 of the distance formed after the filter front cover 203 and the filter rear cover 206 are closed, preferably 1 / 4.

[0068] The lower part of the filter front cover 203 and the lo...

Embodiment 2

[0072] In the lint filtering device of the above specific embodiment, in order to avoid space for the rotation of the rotating shaft structure, the guide rib 110 generally has a distance of about 0.5mm from the rotating shaft structure, and the guiding rib 110 can only be close to the rotating shaft structure at most. In this way, after the filter 200 is installed on the filter cover 100, the water guide baffle will rotate to the part beyond the guide rib 110 under the drive of the rotating shaft structure, and will be pressed by the filter 200, and it often fails to return smoothly. Phenomenon, which greatly affects the efficiency of lint collection, thereby affecting the use of users.

[0073] like Figure 7 As shown, in order to solve the above problems, this embodiment adopts the following technical solution: the water guide baffle is installed on the filter cover 100 through the rotating shaft structure, and the two sides of the water guide baffle are arranged along the d...

Embodiment 3

[0077] like Figure 8 and Figure 9 As shown, this embodiment provides a washing machine with the lint filtering device described in the above specific embodiments or embodiments, including an inner tub 400 and a pulsator 300 arranged at the bottom of the inner tub 400, and the lint filtering device Installed on the inner side wall of the inner tub 400 , the lower end of the filter cover 100 of the lint filtering device is installed on the bottom side wall of the inner tub 400 .

[0078] Specifically, the lower end of the filter cover 100 has a first fixed end 107 and a second fixed end 106, the second fixed end 106 is the lower end of the filter cover 100, and the second fixed end 106 is installed on the bottom side of the inner tub 400 On the wall and in contact with the pulsator 300; the first fixed end 107 is formed by the extension of the filter cover 100 toward the inner side of the inner bucket 400, the first fixed end 107 is arranged on the upper part of the second fi...

Abstract

The invention provides an omnibearing thread scrap filtering unit and a washing machine. The filtering unit comprises a filtering cover and a filter, wherein the filter is installed on the filtering cover and provided with a first filtering chamber, a water inlet of the first filtering chamber is formed in the rear portion of the filter, and a water inlet channel of the first filtering chamber is formed between the rear portion of the filter and the filtering cover; a second filtering chamber is formed between the upper portion of the filter and the filtering cover, and water inlets of the second filtering chamber are formed in the two sides of the filtering cover; a filtering portion is arranged on the front portion of the filter and shared by the first filtering chamber and the second filtering chamber. Thread scrap filtration is achieved by feeding water from the two sides of the front portion of the second filtering chamber, discharging water from the front portion of the second filtering chamber, feeding water from the rear portion of the bottom of the first filtering chamber and discharging water from the front portion of the bottom of the first filtering chamber, and thread scrap filtering effect is improved greatly by combining the two filtering modes.

Description

technical field [0001] The invention relates to the technical field of washing machine lint filtering, in particular to an omnidirectional lint filtering device and a washing machine. Background technique [0002] At present, there are three types of lint filters commonly used in pulsator washing machines on the market: box type fixed type, mesh bag type swing type and mesh bag type fixed type. Among them, the box-type fixed lint collection effect is poor. According to the calculation of one machine with two lint filters, the lint collection rate of one washing program is about 60%; one swing type swing type lint filter and one program line The crumb collection rate is about 50%, but the swing type lint filter is easy to hang clothes and fall off during the washing process; the effect of the mesh bag fixed lint filter is basically the same as that of the box type fixed type, and the lint collection rate is also lower. , and the mesh bag is prone to wear and aging during use...
