Washing machine and circulating water-saving filter device with self-cleaning function for washing machine

[0046] Such as Figure 4 As shown, the filter mechanism 12 in this embodiment is vertically arranged in the filter container 11, the rotary joint 122 is arranged at the bottom of the filter mechanism 12, and the self-cleaning mechanism is arranged on the side wall of the filter container. This structure effectively uses water pressure and gravity to flush the filter screen, and the filter screen is cleaned more cleanly.

[0048] Such as figure 2 with image 3 As shown, the difference between this embodiment and the above-mentioned first embodiment is that: the axial direction L of the filter mechanism 12 rotates and the horizontal plane R has an inclined angle α, 0 ≤ α ≤ 30°, preferably 1° ≤ α ≤ 10 °, preferably 1°≤α≤3°, the rotary joint 122 is located at the lower end of the filter mechanism 12; by tilting or horizontally placing the filter mechanism, not only the filtering area can be increased, the filtering speed can be accelerated, but also the filter screen can be cleaned .

[0049] The structure can be realized in the following ways: 1. The filter container is arranged horizontally, and the filter mechanism is arranged obliquely; 2. The filter container and the filter mechanism are arranged obliquely together, and a support base is provided below the filter container.

[0050] Compared with the vertical arrangement of the filter mechanism in Embodiment 1, the advantages of the filter mec

[0052] Such as Figure 4 As shown, the spray head 13 described in this embodiment is a tubular structure with one end closed and the other end connected to the cleaning water. The peripheral wall of the spray head 13 is provided with at least one water spray port 130 along the axial direction. The shape of the water spout 130 is circular, elliptical, strip-shaped, etc. The length of the nozzle should ensure that the width of the sprayed water flow is enough to cover the axial length range of the entire filter screen.

[0053] The tubular nozzle 13 can be provided in multiples, distributed on the side wall of the filter container 11, and arranged parallel to the rotation axis of the filter mechanism 12.
