S1: Get the water level height in the water receiving chamber;

S2: Control the opening and closing states of the first water discharge valve and the second water discharge valve according to the height of the water level in the water receiving chamber.

Specifically, in step S1, the controller can obtain the water level height in the water receiving chamber through the water level sensor 1325, as a basic parameter for subsequent judgment. Of course, the present invention does not impose any restrictions on the specific acquisition method of the water level height, and those skilled in the art can also set other methods according to actual use requirements.

Further, in step S2, as a preferred control method, step S2 specifically includes: if the water level height in the water receiving chamber reaches a preset height, the water in the water receiving chamber is left to stand for the first time. After the preset time period, the second water discharge valve 1324 is opened to release the water at the top of the water receiving chamber; after the water at the top of the water receiving chamber is released, the second water discharge valve 1324 is closed; After a preset time period, the first water release valve 1322 is opened to release the water at the lower part of the water receiving chamber, and after the water level drops to the bottom sedimentary layer is completely discharged, the first water release valve 1322 is closed to finally obtain clean water.
