Thereby, the arrangement of the drain pipe 200 and the drain valve 700 is facilitated, and whether the drain pipe 200 drains water or not can be controlled by using the drain valve 700.
In some specific examples of the present invention, as shown in fig. 1 to 4, the drain mechanism 30 for the washing machine further includes a blocking lever 500. The blocking lever 500 is movably provided to the housing 100 between a blocking position and a releasing position, and the blocking lever 500 is drivingly connected to the drain pipe 200 to move in synchronization with the drain pipe 200.
Wherein, when the drain pipe 200 is located at the extended position, the blocking rod 500 is located at the blocking position and blocks the rotation of the dehydration barrel 20, for example, the outer bottom wall of the dehydration barrel 20 is provided with a groove 23, the upper end of the blocking rod 500 extends into the groove 23 to block the rotation of the dehydration barrel 20, wherein the groove 23 can be arranged on the flange 22 at the bottom of the dehydration barrel 20.
