A washing machine as claimed in claim 2, wherein the rotation shaft is parallel to the tub shaft, the distance between the drain opening and the tub shaft of the tub is L, the distance between the rotation shaft and the tub shaft of the tub is L1, the distance between the shaft center end and the outer peripheral end is L2, l1+l2> L1; and the distance between the rotation axis and the water outlet is L4, L2> L4.
4. A washing machine as claimed in claim 3 wherein the push rod is arranged below the bottom of the tub and is telescopically mounted on the washing machine in a direction parallel to the tub axis, at least part of the push rod being coincident with the water deflector in the tub axis direction when extended, and all of the push rod being staggered with the water deflector in the tub axis direction when contracted.
5. A washing machine as claimed in claim 4, wherein the distance between the axis of the push rod and the tub axis of the tub is L3, l1+l2> L3> L.
6. A washing machine as claimed in any one of claims 1 to 5 wherein the peripheral end of the splash plate has an extension in a circumferential direction of rotation about the axis of rotation to form a peripheral side, the first and second pawls being disposed in sequence in a clockwise direction at opposite ends of the peripheral side of the splash plate.
7. The washing machine as claimed in claim 6, wherein the upper and lower parts of the outer peripheral side of the water guard are a first guide groove and a second guide groove recessed toward the rotation axis direction, respectively, one end of the first guide groove being a first pawl, and one end of the second guide groove being a second pawl; when the water baffle seals the water outlet and is in a sealing position, the distance between each point on the first guide groove and the barrel shaft is smaller than or equal to the distance between the push rod and the barrel shaft; when the water baffle opens the water outlet and is in the opening position, the distance between each point on the second guide groove and the barrel shaft is smaller than or equal to the distance between the push rod and the barrel shaft.
8. A washing machine as claimed in any one of claims 1 to 5 wherein a return torsion spring is provided at the hinge of the water guard and the tub for driving the water guard to return to the original position; when the water baffle is at the initial position, the distance between the peripheral side edge of the water baffle and the barrel shaft is greater than the distance between the push rod and the barrel shaft.
9. A washing machine as claimed in any one of claims 1 to 5 wherein locking means are provided on the tub for locking the relative position between the water deflector and the tub when the water deflector is rotated to the closed position closing the drain opening.
10. A washing machine as claimed in any one of claims 1 to 5 wherein the tub is provided with a water level sensor for detecting the water level in the tub and/or a position sensor for detecting the relative position between the water deflector and the tub.
