Technical Field

The invention relates to the technical field of washing machines, in particular to a floating filtering device and a washing machine.

Background

The filigree filtering device of the washing machine can collect and filter filigree such as cotton thread, fine velvet and/or batting on the clothes under the action of water circulation, thereby the clothes washed by the washing machine can not be stuck with a lot of impurities. The thread scraps filtering device of the existing washing machine is fastened in the middle position of the inner cylinder of the washing machine, and the thread scraps filtering device is fixed in position and cannot move. Taking the pulsator washing machine as an example, when the installation position of the thread scraps filtering device is higher, the water flow can not reach the height of the thread scraps filtering device under the condition of low water level of the washing machine, so that the thread scraps filtering device loses the filtering effect; when the installation position of the lint filter is low, lint is mainly concentrated on the upper part of water in the case of a high water level of the washing machine, and the lint collecting effect of the washing machine is also reduced. The poor thread scrap collecting effect of the thread scrap filtering device can lead to more thread scrap residues on the washed clothes, and the washing effect of the washing machine is reduced.

Accordingly, there is a need for a floating filter device and a washing machine that solve the above problems.

Referring to fig. 1 to 4, the present embodiment provides a floating filter device for filtering and collecting impurities such as lint in an inner tub 1 of a washing machine. The embodiment is described taking the application of the floating filter device to a pulsator washing machine as an example, and in other cases, the floating filter device may be applied to other types of washing machines or other household appliances.

The floating filter device of the present embodiment includes: at least two slide ways arranged on the inner cylinder 1 of the washing machine, and the heights of the at least two slide ways along the axial direction of the inner cylinder 1 are different. Each slide is slidably provided with a filtering device 2, the filtering device 2 comprises a floating mechanism 21, a collecting mechanism 22 and a sliding mechanism 23, the sliding mechanism 23 is slidably arranged in the corresponding slide, the collecting mechanism 22 is connected with the sliding mechanism 23, the floating mechanism 21 is connected with the collecting mechanism 22, and the floating mechanism 21 is configured to drive the collecting mechanism 22 to slide along the slide under the action of floating force.

In this embodiment, the filtering device 2 is slidably disposed on the inner cylinder 1, and the floating mechanism 21 is suspended on the water surface due to the buoyancy of the washing water in the inner cylinder 1, so as to drive the collecting mechanism 2 to suspend on the water surface. The above arrangement enables the position of the filtering device 2 to be changed along with the change of the water level, so that the function of collecting the thread scraps in the washing water by the filtering device 2 is realized under the height of each water level in the inner barrel 1, the collection efficiency of the foreign matters such as the thread scraps is improved, and the user experience is improved. In addition, in the embodiment, by arranging at least two slide ways with different heights, when the water level in the inner cylinder 1 is at a low water level, at least two filtering devices 2 can float on the water surface and filter the thread scraps in the water; when the water level in the inner cylinder 1 is at a high water level, the filtering device 2 in the higher slide way floats on the water surface to filter the thread scraps on the water surface, and the filtering device 2 in the lower slide way is suspended at the lower part of the water to filter the thread scraps on the underwater part. That is, the present embodiment realizes a function of filtering the washing water in the inner tub 1 in layers at different heights. Therefore, the filtering device 2 of the embodiment can ensure the collection effect of the lint no matter in low water level or high water level, so that the lint on the washed clothes is reduced to the greatest extent, and the washing effect of the washing machine is greatly improved.

As shown in fig. 4, the sliding mechanism 23 of the present embodiment preferably includes a slider 231 and a supporting frame 232, wherein the slider 231 is slidably mounted in the slideway, one end of the supporting frame 232 is fixedly connected with the slider 231, and the other end of the supporting frame 232 is connected between the collecting mechanism 22 and the floating mechanism 21.
