after the rotating speed of the inner cylinder reaches a set value, the valve core moves and opens the water outlet under the action of centrifugal force by using self weight.
9. A washing machine as claimed in any one of claims 1 to 3 wherein the valve comprises,
the valve core is movably arranged in the concave part and correspondingly seals the water outlet at the initial position;
the elastic piece is clamped between the valve core and the concave part, or the inner cylinder wall, or the mounting plate so as to limit the movement of the valve core and provide acting force for the valve core to reset to the initial position;
the balancing weight is connected with the valve core through a connecting structure so as to pull the valve core to move and open the water outlet under the action of centrifugal force after the rotating speed of the inner cylinder reaches a set value;
preferably, the balancing weight is connected with the valve core through a connecting rod, and the middle part of the connecting rod is hinged with the inner concave part, so that the balancing weight and the valve core rotate and move around the hinged part.
10. A washing machine as claimed in claim 8 or 9, wherein the resilient member extends radially of the inner drum, one end of the resilient member being connected to the valve core and the other end being connected to the recess.
