Title: WATER SUCTION PUMP AND WASHING MACHINE
Abstract:
Disclosed are a water suction pump and a washing machine. The water suction pump comprises an impeller (4), a water suction chamber cover (5) and a pump body cover (2). An impeller chamber (12) for accommodating the impeller (4) is arranged on one side of the water suction chamber cover (5), and the other side thereof matches the pump body cover (2) and forms a water suction chamber (13). The impeller chamber (12) is in communication with the water suction chamber (13). The pump body cover (2) is provided with a water suction inlet (8) and a water drain outlet (9). The water suction chamber (13) is internally provided with a flow guide mechanism (7) and a one-way check mechanism (6). The flow guide mechanism (7) is in communication with the water suction inlet (8). The one-way check mechanism (6) is arranged to match the flow guide mechanism (7) for a water flow to enter the water suction chamber (13) from the water suction inlet (8) in one way. The water suction pump has a simple structure, miniaturized volume, low noise and high reliability. The water suction pump can be mounted on the washing machine and can use bath water or other water resources that can be reused twice, thereby effectively saving on water. The water suction pump can be also used alone, and secondary water is used for other purposes, such as watering flowers and irrigating fields, thereby fully and effectively utilizing the water resources.
