Embodiment 1

[0039] see figure 1 , a washing machine with a self-cleaning filter, the filter 11 is fixed on the bottom of the inner tub 12 of the washing machine, the outer diameter of the filter 11 is larger than the diameter of the drainage center hole 121 at the bottom of the inner tub 12, and the bottom of the inner tub 12 is provided on the side for The opening 122 through which the washing water passes; the filter 11 uses the washing water to flow through the filter 11 from the bottom of the filter 11 and enters the inner barrel 12 for circulation to realize its filtering function, and the washing water flows through the filter 11 through the drainage center hole 121 to drain to realize its self-discharging. Cleansing effect.

[0040] The filter 11 is fixed on the bottom of the inner tub 12 of the washing machine to avoid occupying the volume of the inner tub 12; the outer diameter of the filter 11 is greater than the diameter of the drainage center hole 121 at the bottom of the inne...

Embodiment 2

[0046] Figure 6 to Figure 8 Embodiment 2 is shown, in which components identical or corresponding to those in Embodiment 1 use the same reference numerals as in Embodiment 1. For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described. The difference is that the filter 11 is a stainless steel plate with a plurality of water holes 114 evenly distributed on the stainless steel plate. During the circulation process, the washing water passes through the filter 11, the water flows through the water hole 114, and the wire scraps adhere to the bottom surface of the stainless steel plate. When the washing water washes the stainless steel plate, the surface of the stainless steel plate is smooth and easy to rinse. In this embodiment, the diameter of the water hole 114 is between 4 mm and 6 mm.

[0047] see Figure 6 and Figure 8 , the edge of the stainless steel plate is provided with a curling 113, and the curling 113 is formed by bending the edge of...

Embodiment 3

[0050] Figure 9 to Figure 11 The third embodiment is shown, wherein the parts identical or corresponding to those of the second embodiment adopt the same reference numerals as those of the second embodiment. For simplicity, only the differences between Embodiment 3 and Embodiment 2 are described. The difference is that the filter 11 is a stainless steel plate, the edge of the stainless steel plate is provided with a reinforcing rib 116, the cross section of the reinforcing rib 116 is U-shaped, the reinforcing rib 116 covers the edge of the stainless steel plate, and the reinforcing rib 116 is formed by injection molding. The setting of the reinforcing rib 116 makes the edge thicker, increases the strength and service life of the filter 11, and is not easy to bend during installation. The setting of the reinforcing rib 116 also makes the original sharp edge of the stainless steel plate not exposed, so it will not cause harm to the handling and installation personnel.

Abstract

The invention discloses a washing machine with a self-cleaning filter and a control method thereof. The filter is fixed to the bottom of an inner tub of the washing machine and does not occupy the volume of the inner tub, the outer diameter of the filter is larger than the diameter of a drainage center hole in the bottom of the inner tub, an opening through which washing water flows is formed in the side face of the bottom of the inner tub, the washing water flows through the filter from the bottom of the filter to enter the inner tub to be circulated to achieve the filtering effect, the washing water can sequentially pass through the opening in the bottom of the inner tub, the filter and the bottom of the inner tub from the interior of the inner tub and then is returned to the interior ofthe inner tub to form a cycle, the water circulation path is shortened, the water velocity and impact force are ensured, it is ensured that most water is drained from the opening and flows downwardsdirectly to be returned to the inner tub through the filter, and the filtering effect is further improved; the washing water flows through the filter from a drainage center hole to achieve drainage sothat the self-cleaning effect can be achieved, the filter is washed by the washing water, the contamination caused by line scrap accumulation is avoided, and the filter does not need to be disassembled artificially to be cleaned.

Description

technical field [0001] The invention relates to the technical field of washing equipment, in particular to a washing machine with a self-cleaning filter and a control method thereof. Background technique [0002] Along with the raising of people's living standard, washing machine has become one of main household appliances of people's daily life now. The pulsator fully automatic washing machine is favored by many consumers because of its short washing time and clean washing. During the washing process of the washing machine, the friction between the washing machine and the clothes produces lint, and the lint is attached to the inner and outer barrel walls of the washing machine with the movement of the washing water. Over time, more lint accumulates, which is not only easy to breed Bacteria, affecting the flow of washing water, and some lint on the wall of the bucket enters the washing water during the next laundry, causing secondary pollution of the washing water, seriousl...
