Washing apparatus

A washing apparatus, comprising:

• an outer cylinder, a hole-free inner cylinder, a drainage valve group, and a drainage pipe group;
• the outer cylinder is communicated with the outside through the drainage pipe group;
• the hole-free inner cylinder is coaxially rotatably arranged inside the outer cylinder, and a drainage port is provided on a cylinder wall of the hole-free inner cylinder;
• the drainage valve group comprises a connection assembly, an elastic member, and a valve core, and the valve core is connected to the hole-free inner cylinder through the connection assembly and the elastic member respectively;
• the elastic member is configured to be capable of urging the valve core to maintain a state of blocking the drainage port in non-drainage situations, and to be capable of allowing the valve core to move away from the drainage port by means of a centrifugal force overcoming an elastic force through elastic deformation of the elastic member when the hole-free inner cylinder rotates for drainage, thereby opening the drainage port;
• and
• the connection assembly is configured to be capable of guiding the valve core to move away from the drainage port in drainage situations, and to be capable of guiding the valve core to move for resetting through a springback action of the elastic member in non-drainage situations.
