Abstract (en)
[origin: EP3369856A1] A drainage structure of a water-saving washing machine and the washing machine, a central hole (1) is arranged at the inner tub bottom (29) of the washing machine, and an annular groove (2) is arranged around the central hole (1) ; the inner part and the outer part of the inner tub (29) are communicated with a water flow passage on the annular groove (2), and the annular groove (2) is provided with an sealing member (3) capable of reciprocating motion for controlling the on-off state of the water flow passage. The upper part of the sealing member (3) is provided with an elastic member (4) for controlling the downward movement of the sealing member (3) to contact with the inner tub bottom (7) and/or the bottom surface of the annular groove (2), and the lower part of the sealing member (3) is provided with an driving member (5) for controlling the upward movement of the sealing member (3) to separate from the inner tub bottom (7) and/or the bottom surface of the annular groove (2). As the control of the drainage is so long as controlling the reciprocation of the sealing member (3), the control is simple; in addition, the sealing member (3) is disposed in the inner annular groove (2) at the inner tub bottom (7), and it is relatively fixed with the inner tub (29) at the rotational direction. In this way, the wear of the sealing member (3) is small, and the reliability is high; the accuracy demand of the positioning of the inner tub (29) is lower, and the positioning structure and the control program of the inner tub (29) is simplified; all the seals are the end face contacting seals, which are reliable.
