Embodiment 1

[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.

Embodiment 2

[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 ...

Embodiment 3

[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.

Abstract

The invention discloses a washing machine and a circulating water-saving filter device with a self-cleaning function for the washing machine. The circulating water-saving filter device comprises a filter container, a filter mechanism and a self-cleaning mechanism. The filter mechanism is rotatably arranged inside the filter container, the self-cleaning mechanism can drive the filter mechanism to rotate by the aid of inlet water flow, and the filter mechanism can be sprayed and cleaned by the self-cleaning mechanism. The washing machine comprises an outer barrel of the washing machine. The outer barrel, a flocculation device, the filter device and the outer barrel are sequentially communicated with one another via pipelines in a circulating manner, the flocculation device comprises a flocculation container and a flocculating agent dispenser, the flocculation container is communicated with the outer barrel, flocculating agents are dispensed into the flocculation container by the flocculating agent dispenser, and water is drained from the outer barrel into the flocculation container and is subjected to flocculation treatment in the flocculation container. The filter device comprises the filter container and the filter mechanism in the filter container. The filter container is communicated with the flocculation container and the outer barrel, and the water in the flocculation container is filtered by the filter mechanism after the water is subjected to flocculation treatment, and then is drained into the outer barrel to be reused. The washing machine and the circulating water-saving filter device have the advantages that the automation degree can be upgraded, the washing machine and the circulating water-saving filter device are simple in structure, and energy can be saved.

Description

technical field [0001] The invention relates to washing machine circulating water treatment equipment, in particular to a washing machine circulating water-saving device adopting a flocculation filtering method, especially a washing machine circulating water-saving filtering device with a self-cleaning function and a washing machine. Background technique [0002] With the improvement of people's living standards, the washing machine has become one of the main household appliances in people's daily life. The washing process of the washing machine mainly includes several stages of washing, rinsing and drying. After entering the rinsing stage, in order to rinse off the stains and residual detergent, it is necessary to enter more water or perform more rinsing times to rinse the clothes, which will consume a lot of water resources, even if it is a water-saving drum washing machine. Clothes also need to be rinsed at least twice, and this process consumes at least 30L of tap water....
