Referring to fig. 11 and 12, it is more preferable that semicircular grooves 311 are respectively formed in the two second semicircular plates 310 of the second washing plate 300 in the radial direction, and when the second washing plate 300 is folded in half, the two semicircular grooves 311 contain the driving shaft 500 (except for the mounting seat 520 at the bottom of the driving shaft 500), which does not affect the folding of the second washing plate 300 and can protect the driving shaft 500.

Referring to fig. 14 and 15, in a preferred embodiment of the present invention, the second washing board 300 is fixed to the insertion board 110 on the side wall of the washing tub 100 by clamping, specifically: a plurality of elastic buckles 340 are arranged on the edge of the second washing plate 300 along the circumferential direction, the buckling grooves 111 are correspondingly arranged on the inserting plate 110, and the elastic buckles 340 are inserted into the buckling grooves 111 after being deformed so as to fix the second washing plate 300; the elastic buckle 340 is designed as a U-shaped buckle with an upward opening, and the U-shaped buckle has good elastic deformation capability and can provide a larger operation space for a user, for example, when disassembling, the user's finger can go deep into the U-shaped buckle to apply force to the center of the second washing board 300, so that the U-shaped buckle is separated from the buckle slot 111.

Of course, the present invention is not limited to the above embodiments, and according to the design concept of the present invention, those skilled in the art can think that: the positions of the first washing plate 200 and the second washing plate 300 are interchanged, that is, as shown in fig. 18, the second washing plate 300 is located above the first washing plate 200, the first washing plate 200 is located above the pulsator 400, the pulsator drives the first washing plate 200 to move up and down in the washing tub 100 through the transmission shaft 500 to change the relative distance between the first washing plate 200 and the second washing plate 300, so as to form a washing space with a variable height.

The utility model provides another kind of washing mode: the first washing plate 200 may be disposed in the washing tub 100, and after the laundry is put into the washing tub 100, the first washing plate 200 covers the laundry, and in the washing process, the first washing plate 200 performs a lifting motion in the washing tub 100 to circularly squeeze the laundry in the washing tub 100, and the rotating motion of the washing water and the lifting motion of the first washing plate 200 cooperate to achieve a pressure washing effect. The washing mode is suitable for washing clothes with low washing requirements.

In the above embodiments, the number of the first washing plates is not limited to one, and two, three, etc. first washing plates may be arranged to realize the layered pressure washing according to actual conditions.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
