According to the present invention, the water suction pump 2 is used to connect the water suction pump water inlet 21 to the bathtub in the home, so that the function of washing with the bath water can be realized, thereby reducing the water consumption of the washing machine.

The washing machine of the present invention further includes a water inlet water path independent of the above-described water suction pump 2. In this embodiment, the water inlet water passage is connected to the tap water in the home, and the switch is controlled by the water inlet valve 9. The flow channel distribution chamber 5 has a first water inlet end 511 and a first water outlet end 512 respectively communicating with the first flow channel 51. The first water inlet end 511 is in communication with the inlet water passage of the washing machine, and the first water outlet end 512 is in communication with the pump chamber of the water suction pump 2.

In general, the suction pump must be pumped before operation, that is, the pump chamber is filled with liquid. This requires a separate water supply valve to control all the influent water into the pump chamber of the suction pump to complete the pumping operation. Let the suction pump start working normally. The first flow passage 51 of the present invention is in direct communication with the inlet water passage independently of the suction pump 2, so that the main inlet water and the suction pump 2 are connected in parallel, and when the inlet water passage is in water, the pump is simultaneously supplied to the suction pump 2. The filling of the cavity, that is, the process of pumping, enables the suction pump to be started quickly after the inlet water circuit is opened, eliminating the need for a separate water supply inlet valve for the suction pump to start the pump. .
