Embodiment Construction

[0043] figure 1 and figure 2 is a schematic schematic diagram of a washing machine according to an embodiment of the present invention. see figure 1 and figure 2 The washing machine in the embodiment of the present invention may include a casing (not shown in the figure), a washing tub 12 and a filter membrane assembly 26 disposed in the casing. In some optional specific embodiments of the present invention, the washing tub 12 generally consists of an outer tub and an inner tub that can rotate inside the outer tub. Washing tub 12 top is provided with clear water inlet, and it connects tap water outlet by pipeline 11, when opening valve 13 on the pipeline 11, can enter washing with clear water or rinse with clear water in washing tub 12. Usually, a drain port is provided at the bottom of the washing tub 12 , and the drain port communicates with the water inlet of the filter membrane module 26 through a pipeline.

[0044]The filter membrane module 26 of the embodiment of ...

Abstract

The invention provides a washing machine and a control method thereof. The washing machine comprises a washing cylinder, a filtration film assembly and a pumping device arranged on a pipeline between a water outlet of the washing cylinder and the filtration film assembly. The pumping device is configured in a way that during the filtering and water-producing stage of the filtration film assembly, the pumping device works in a first pumping manner and has first lift in order to pump water in the washing cylinder to the filtration film assembly, and the water level of water in the filtration film assembly is not higher than the lower edge of a discharge opening of the filtration film assembly. By means of different lifts of the pumping device, functions of the washing machine in different working stages are achieved, during the filtering and water-producing stage of the filtration film assembly, the low-lift water pump enables the water level of water in the filtration film assembly to be not higher than the lower edge of the discharge opening of the filtration film assembly, and therefore water from the washing cylinder can be discharged from the discharge opening of the filtration film assembly, and the fact that during the water filtration period, the total water amount of the washing cylinder basically keeps unchanged is guaranteed.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine with a filter membrane assembly and a control method thereof. Background technique [0002] A laundry routine of conventional washing machines usually includes water intake, washing-spin-drying-drainage, multiple rinsing-spin-drying-drainage, etc., wherein washing and each rinse need to consume a large amount of clean water. The water used for washing or rinsing is discharged to the environment outside the washing machine through the drain pipe. The whole washing process consumes a lot of water, which greatly wastes water resources. [0003] In order to achieve the purpose of saving water, the washing water and / or rinsing water of the washing machine can be filtered by the filter membrane module for recycling. However, as the washing times of the washing machine increase, separated substances and some other impurities will gradually accumulate on the surface of the filter ...
