Embodiment Construction

[0049] figure 1 is a schematic schematic diagram of a washing machine according to an embodiment of the present invention. The washing machine may include a washing tub 12 , a drain pump 14 , a filter assembly and a flow switching device 22 . The washing tub 12 is generally composed of an outer tub and an inner tub that can rotate in the outer tub. The bottom of the washing tub 12 is provided with a drain port, and the drain port communicates with the filter assembly via a drain pump 14 through a pipeline. According to needs, for example, in the washing program or rinsing program of the washing machine, the water in the washing tub 12 can be pumped out, transported to the filter assembly for filtering, and then circulated back to the washing tub 12 for reuse.

[0050] exist figure 1 In the illustrated embodiment, the filter assembly can be composed of a coarse filter 24 and a fine filter 26 located downstream of the coarse filter 24 (those skilled in the art should understa...

Abstract

The invention provides a washer. The washer comprises filter components and a flow switching device, wherein the filter components in pairs are configured to filter water pumped by a washing cylinder of the washer, so as to circulate the water in the washing cylinder for reuse; the flow switching device is at least provided with a cleaning port for fluid to flow in and a discharge port for draining the fluid out of the washer; the flow switching device is configured to conduct or break over the cleaning port and the discharge port in a controlled way, so as to form a cleaning flow path when the cleaning port and the discharge port are conducted, and drain the cleaning fluid out of the washer after the filter components are washed. The washer provided by the invention has an optimized flow layout and a control way, the filter components in a circulating water filter system can be automatically cleaned by a cleaning flow path, the life of the filter components in the washer can be prolonged, and the higher filtration flux can be ensured all the time; furthermore, a dense drain flow path, a spraying flow path, a pure water washing flow path and the like can be provided to meet the demands of the washer in different operating processes.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine with circulating water filtering function. Background technique [0002] The working process of conventional washing machines usually includes water intake, washing-spin-drying-drainage, multiple rinsing-spin-drying-drainage, etc., wherein each rinse needs to consume a large amount of clean water. Generally speaking, the water consumption of the entire working process of the existing pulsator washing machine can reach 20-30 liters per kilogram of clothing, while the water consumption of the entire working process of the existing drum washing machine can also reach 12 liters of water per kilogram of clothing. That is to say, when the existing conventional washing machine (regardless of the pulsator washing machine or the drum washing machine, and no matter whether it is a semi-automatic washing machine or a fully automatic washing machine) is working, it generally discharges ...
