Abstract
A washing apparatus to solve the problems in existing washing machines of a drain solenoid valve of a non-porous inner drum being prone to circuit failure and the requirement for the overall layout being excessively high. A drain valve group is configured such that a drain outlet can move and open merely under a centrifugal force generated by the rotation of a non-porous inner drum, without the need to electrically drive a valve core to move, so as to allow the non-porous inner drum to discharge water outwards, and the drain outlet can be reset and blocked under an elastic force, thus achieving no-power operation. When the drain valve group is configured on the non-porous inner drum, it is not necessary to consider the spatial layout and waterproofing of power elements and their circuits, reducing the drainage arrangement costs when the washing machine is equipped with a non-porous inner drum.
