The switching between the washing water circulation channel and the sewage discharge channel is realized in a valve switching mode, and the switching between the two working states is more reliable. Also, based on the function of the switching valve 5, the drain function is disabled when the washing water circulates, and the washing water circulation function is disabled when the sewage is discharged, thereby preventing the drain and the washing from being simultaneously performed due to the circuit failure.
In order to simplify the structure of the switching valve 5 and ensure the reliability of the switching valve 5, and to prevent the sewage in the drain pipe 4 from flowing back into the water cup 1, further, the first water outlet 52 is located between the circulating water inlet 51 and the muddy water inlet 55, and the first water inlet 53 is located between the second water outlet 56 and the second circulating water outlet 54; the valve core 57 comprises a valve rod 571, a first plug 572 and a second plug 573, and the first plug 572 and the second plug 573 are both fixedly installed on the valve rod 571; the distance between the first plug 572 and the second plug 573, the distance between the circulating water inlet 51 and the second circulating water outlet 54, and the distance between the turbid water inlet 55 and the second water outlet 56 are all L; the first plug 572 is used for plugging the dirty water inlet 55 or the circulating water inlet 51, and the second plug 573 is used for plugging the second water outlet 56 or the second circulating water outlet 54.
Based on the distance arrangement of the two plugs and the position arrangement of each water gap, when the valve core 57 makes the circulation water inlet 51 communicate with the first water outlet 52 and makes the first water inlet 53 communicate with the second circulation water outlet 54, the first plug 572 seals the dirty water inlet 55, and the second plug 573 seals the second water outlet 56, so that the switching valve 5 has a stop function, the washing water circulation path and the sewage discharge path are sealed, and the sewage in the sewage discharge path can be effectively prevented from entering the washing water circulation path. Moreover, based on the position settings of the first water outlet 52 and the first water inlet 53, both the two plugs do not block the first water outlet 52 and the first water inlet 53 in the washing water circulation state and the sewage discharge state, so that the water pump 2 can normally operate.
