  • Patent number: 10358762
    Abstract: A washing machine has cleaning particles provided between an outer barrel and an inner barrel. A water outlet on the outer barrel communicates with a drainage device including a drain valve body having a particle receiving and discharging chamber and a drainage chamber. The particle collecting and discharging chamber has a water inlet. The drainage chamber has a water outlet. A particle filtering structure is provided between the particle receiving and discharging chamber and the drainage chamber. One side of the particle collecting and discharging chamber has an opening with a sealing cover including an outer cover and an insertion portion inserted through the opening, and fitting the edge wall of the particle receiving and discharging chamber. An inner wall of the insertion portion has a plurality of protrusions for supporting the cleaning particles. Gaps between the protrusions are smaller than a minimum diameter of the cleaning particles.
