As shown in fig. 1, the drain assembly of the washing apparatus using the siphon effect further includes a drain valve 70. A drain valve 70 is provided on the tub drain 30 for controlling opening or closing of the tub drain 30. Specifically, since the tub drain 30 directly communicates with the bottom of the tub washing compartment 10, the water in the tub washing compartment 10 can be drained directly through the tub drain 30 by gravity. The drain valve 70 is provided to control the opening and closing of the tub drain line 30, thereby preventing water leakage from the tub washing chamber 10 during washing. In addition, by arranging the drain valve 70, the water in the outer barrel washing cavity 10 can be prevented from being mixed with the water in the door body washing cavity 20, cross infection is avoided, and the effect of separately washing the two cavities is realized.
