Embodiment 1

[0070] Such as figure 2 , image 3 , Figure 4 As shown, the pre-filter 6 in this embodiment includes an outer cylinder wall 22, an upper end cover 20 and a lower end cover 21 at both ends of the outer cylinder wall 22, the outer cylinder wall 22 is a hollow cylinder, and a filter screen support frame is arranged inside 23. The filter screen support frame 23 is covered with a filter screen 17. The upper end cover 20 and the lower end cover 21 of the pre-filter 6 are fixed by rotation through the buckle structure, and there are anti-loose protrusions at the buckle. The pre-filter 6 , Sealing rings are set at the joints of each component to ensure smooth flow of each pipeline without mixed flow. The pre-filter 6 is provided with a first inlet 7 before the filter screen 17, a first outlet 9 is provided before the filter screen 17, and a second outlet 10 is provided after the filter screen 17, wherein the inlet is located on the end cover at one end, and the outlet is located a...

Embodiment 2

[0073] Such as figure 1 , Figure 5 As shown, the cleaning method described in this embodiment is specifically: open the air pump 14 and the second valve 19, the gas generated by the air pump 14 enters the pre-filter 6 through the third inlet 13, is discharged through the second outlet 10, and passes through the second inlet 8 enters the main filter 5, is discharged through the third outlet 13, and is discharged through the second valve 19 through the drain pipe 26 of the washing machine. The gas generates bubbles in the water, and the movement, explosion or vibration of the bubbles will affect the pre-filter 6 and the main filter 5. The filter screen is air-washed, and after 10s-120s, close the air pump 14 and the second valve 19, open the drain pump 4 and the first valve 18, the water flow enters the pre-filter 6 through the first inlet 7, and is discharged through the first outlet 9. The filter screen 17 of the pre-filter 6 is washed by water flow, and the water flow toget...

Embodiment 3

[0075] Such as figure 1 , Figure 6 As shown, the cleaning method described in this embodiment is specifically: open the air pump 14 and the first valve 19, the gas generated by the air pump 14 enters the pre-filter 6 through the third inlet 13, is discharged through the second outlet 10, and passes through the first valve. 18 is discharged through the drain pipe 26 of the washing machine, the gas generates bubbles in the water, and the air-washing of the filter screen 17 of the pre-filter 6 is carried out by the movement, explosion or vibration of the bubbles. After 10s-120s, the air pump 14 is turned off, the drain pump 4 is turned on, and the water flows through The first inlet 7 enters the pre-filter 6, and is discharged through the first outlet 9. The filter screen 17 of the pre-filter 6 is washed by the washing of the water flow, and the water flow together with the filtered lint and granular impurities pass through the first valve. 18 is discharged through the washing ...

Abstract

A water-saving washing machine and a control method. The washing machine comprises a washer drum and an outer drum (1). A cycle pipeline is arranged between a drainage outlet (2) of the outer drum and a water inlet (3) of the outer drum. A drainage pump (4) and a main filter (5) are arranged on the cycle pipeline. A pre-filter (6) is also arranged on the cycle pipeline. The pre-filter (6) is located between the drainage pump (4) and the main filter (5), and a filter screen density of the pre-filter (6) is lower than a density of a filter screen of the main filter (5). Large-particle impurities are prevented from entering the main filter (5) to damage the main filter (5). A service life and a use effect of the main filter (5) can be improved. Water in drums during a washing and rinse process is in a clean water state. Clothes are always washed in clean water. Sense and psychology of a user are improved. Filters are washed to prevent the filters from being blocked, prolong a service life of the filters, prevent filtering effect deterioration or unavailability of the filters due to too many impurities, and reduce maintenance costs.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a water-saving washing machine and a control method. Background technique [0002] Along with the raising of people's living standard, washing machine has gradually become one of necessary household appliances in people's family, and most people regard washing machine as the main tool of washing clothes. With the deterioration of the environment and the pollution of water bodies, clean water resources have gradually become a scarce resource. How to save water and electricity while washing clothes has always been one of the focuses of consumers. [0003] The laundry process of the washing machine mainly includes several stages of washing, rinsing, and drying. In the washing stage, the washing machine is fed with water and detergent to wash the clothes. After entering the rinsing stage, more water is needed to rinse off the stains and residual detergent. or more times of rinsing to...
