Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to a large-flow controllable washing machine valve. Background Art

[0002] The washing machine valve refers to the valve used to control the water inlet and water outlet of the washing machine. In the washing machine, the inlet and outlet of water needs to be controlled by the valve to ensure the normal operation of the washing machine. The washing machine valve usually includes two types: the water inlet valve and the water outlet valve. The water inlet valve is used to control the water entering the washing machine. When the washing machine needs to take in water, the water inlet valve opens, and the water source flows into the sink or bucket of the washing machine through the pipe. When the washing machine does not need to take in water or the water inlet has reached the set water level, the water inlet valve closes to stop the water from entering. The water outlet valve is used to control the discharge of waste water in the washing machine. When the washing machine needs to drain, the water outlet valve opens to discharge the waste water from the washing machine drain pipe. When the washing machine has finished draining or does not need to continue draining, the water outlet valve closes to stop the discharge of waste water. The normal operation of these valves is to ensure that the washing machine can take in water and drain water correctly, and ensure the normal operation of the washing machine.

[0003] The existing patent (publication number: CN219297814U) proposes a washing machine valve. The washing machine valve provided by the utility model has the following beneficial effects: a one-way valve is provided in the water inlet to prevent water backflow; the right end opening of the right chamber can be directly blocked by a sealing block, and a diaphragm is not required, thereby reducing a water leakage point.

[0004] The above-mentioned washing machine valve has only one water inlet, which results in a limited flow rate of the washing machine valve, making it difficult to increase the flow rate according to actual usage conditions. In addition, the washing machine valve uses a solenoid valve to control the switch of the water circuit, which results in it being difficult to flexibly control the flow rate according to the actual conditions during use. Utility Model Content
