Embodiment Construction
[0048] 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 wash tub 12 , a drain pump 22 , a filter assembly and a tee 28 . The washing tub 12 is generally composed of an outer tub and an inner tub that can rotate in the outer tub. The lower part of the washing tub 12 is provided with a drain port, and the drain port communicates with the filter assembly via a drain pump 22 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.
[0049]The three-way device 28 in the embodiment of the present invention is preferably an electronically controlled three-way valve. The ports of the tee arrangement 28 may include a rich port A, a clean port B, and a drain port C fo...

The invention provides a washing machine which comprises a filtering member configured to filter the water discharged from a washing cylinder of the washing machine, the water being cycled to the washing cylinder and reused; and a three-way, apparatus having a cleaning port through which a fluid flows, a concentrated discharge port, and a discharge port for discharging the fluid out of the washing machine. The three-way apparatus is configured in such a way that the cleaning port and the discharge port are controllably conducted or disconnected, so that a cleaning flow passage is formed when the cleaning port and the discharge port are conducted, a cleaning fluid is discharged out of the washing machine after the filtering members are cleaned by the cleaning fluid; and the concentrated discharge port and the discharge port are controllably conducted or disconnected, so that a concentrated discharge flow passage is formed when the concentrate discharge port and the discharge port are conducted, and the washing water from the washing cylinder of the washing machine is discharged out of the washing machine. The washing machine of the invention has an optimal flow passage layout and a control mode, and satisfies the demands of different operation processes of the washing machine.
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 (no matter the pulsator type washing machine or the drum type washing machine, and no matter whether it is a semi-automatic washing machine or a fully automatic washing machine) works, the laundry waste water...
