The second water outlet of the three-way control valve 11 is communicated with the water inlet channel 511 through the slag collecting and cleaning water pipe 12. Thus, by switching different water paths through the three-way control valve 11, the water in the water cup assembly 2 can be provided to the self-cleaning spray arm 5 through the self-cleaning water supply assembly 1, or the water in the water cup assembly 2 can be discharged in time to realize the drain function of the dishwasher.

[0055] Reference Figure 6 , the second kind, the self-cleaning water supply assembly 1 is sequentially communicated with the water cup assembly 2 and the water collecting cavity 21 through the washing pump 7 and the washing water outlet. At this time, the self-cleaning water supply assembly 1 includes a three-way control valve 11 and a slag collecting and cleaning water pipe 12. The three-way control valve 11 has a valve cavity, a water inlet, a first water outlet and a second water outlet. The valve cavity is respectively communicated with the water inlet, the first water outlet and the second water outlet. The water inlet of the three-way control valve 11 is communicated with the washing water outlet of the water cup assembly 2 through the washing pump 7.
