7. A drum washing machine as claimed in claim 5, characterized in that the resonance component comprises a second elastic member, one end of the second elastic member is connected with the resonance block, and the other end is connected with the water inlet valve plate.
8. A drum washing machine according to claim 3 or 5, characterized in that the resonance component comprises a water outlet valve sheet connected with the resonance block, the water outlet valve sheet keeps the water outlet in a normally closed state, and when the rotation speed of the inner drum exceeds a certain value, the resonance block drives the water outlet valve sheet to open the water outlet in the reciprocating process.
9. A drum washing machine as claimed in claim 8, characterized in that the resonance component comprises a third elastic member and a fourth elastic member, one end of the third elastic member is connected with the resonance block, the other end is connected with the water inlet valve plate, the third elastic member provides elastic force for the resonance block to keep at a position where the water inlet valve plate keeps a normally closed state of the water inlet;
one end of the fourth elastic piece is connected with the resonance block, the other end of the fourth elastic piece is connected with the water outlet valve plate, and the third elastic piece provides elastic force for the resonance block to enable the resonance block to be kept at a position where the water outlet valve plate keeps a water outlet normally-closed state.
10. A control method of a drum washing machine according to any one of claims 1-9, characterized by comprising:
the rotating speed of the inner cylinder is controlled to exceed a set value, and the resonance drainage device opens the drainage outlet of the inner cylinder for drainage.
