It should be noted that, in other embodiments, the third preset time, the fourth preset time, and the preset times can also be set in other ways, which are not limited here.

When the washing machine starts to run, the water inlet valve is first opened continuously for 3 seconds. During this period of time, the water with detergent enters the first flow channel 21 through the guide section 30, and since it is only opened for 3 seconds, within the above water injection speed range, The accumulation height of the water in the first flow channel 21 will not exceed the baffle plate 40, so the water only flows into the first flow channel 21 and will not flow into the second flow channel 22; The first flow channel 21 flows out; then the water inlet valve is continuously opened for 3 seconds, and after repeating this for 3 times, the detergent in the drawer box 80 is basically completely washed away by water, and thereafter the first water outlet 51 and the second water outlet 25 All the water that flows out is clear water. Finally, the water inlet valve is continuously opened for the fifth preset time at the preset fourth water injection speed. When water is used, the water can flow out through the first water outlet 51 and at the same time through the second water outlet 25, that is, when the fourth water injection speed is large enough, the first flow channel 21 is not enough to displace all the water. It is completely discharged, so that when the water level accumulation height is higher than the baffle plate 40 between the first flow channel 21 and the second flow channel 22, the water can pass through the guide section 30 and flow into the above-mentioned second flow channel 22 at the same time, so that clean water can pass through The second water outlet 25 flows out, and scours the door glass 60 and the door seal. The fifth preset time can be set according to the amount of water required by the washing machine during laundry.

The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
