When the second transmission member 610 moves downward by the second electromagnetic generator 630, the second elastic member 620 is compressed to store elastic potential energy. When the second electromagnetic generator 630 is powered off, the second transmission member 610 moves upward by the elastic force of the second elastic member 620, so that the second transmission member 610 is separated from the rotation part 222.

In some embodiments, the second locking structure 600 of fig. 1 further includes a locking plate 640, the locking plate 640 extends along the circumferential direction of the inner cylinder rotation shaft 400, the locking plate 640 is sleeved on and fixed to the inner cylinder rotation shaft 400, the locking plate 640 is located between the second transmission member 610 and the rotation portion 222, the second elastic member 620 is located between the second transmission member 610 and the locking plate 640, and the lower end of the second elastic member 620 abuts against the upper surface of the locking plate 640.

Referring to fig. 1 to 10, in the present invention, when the laundry is loaded in the inner tub of the washing machine and the washing starts, the first electromagnetic generator 530 is energized, and the first transmission member 510 moves upward along the axial direction of the inner tub rotation shaft 400 under the action of the magnetic force, so that the first transmission member 510 is engaged with the first connection wall 110 through the engagement gear 700, and the first locking structure 500 is locked. The second electromagnetic generator 630 is de-energized and the second closure structure 600 is opened. The driver 210 drives the rotating disc 220 to rotate, the rotating disc 220 drives the impeller rotating shaft 300 to rotate, and the inner cylinder is limited on the outer cylinder and fixed to clean clothes.

When the object is dehydrated after washing, the first electromagnetic generator 530 is de-energized, the first transmission member 510 moves downward by its own weight and the elastic force of the first elastic member 520, and the first transmission member 510 is separated from the first connection wall 110, so that the first locking structure 500 is opened. The second electromagnetic generator 630 is energized, the second electromagnetic generator 630 generates a magnetic force to move the second transmission member 610 downward, the second elastic member 620 stores elastic potential energy, and the second transmission member 610 is engaged with the rotation part 222. The inner cylinder rotating shaft 400 and the impeller rotating shaft 300 are locked together by a second locking structure 600. The driver 210 drives the rotating disc 220 to rotate, the rotating disc 220 drives the impeller rotating shaft 300 to rotate, and the impeller rotating shaft 300 drives the inner drum rotating shaft 400 to rotate, so that the inner drum rotates at the same circumferential speed along with the impeller, and clothes in the inner drum are dried and dehydrated.

In this application, the inner tube rotating shaft 400 can be locked on the impeller rotating shaft 300, when the washing machine washes objects, the first locking structure 500 is locked, the second locking structure 600 is unlocked, so that the impeller rotates along with the impeller rotating shaft 300, and the inner tube rotating shaft 400 are fixed, thereby improving the washing efficiency of the impeller. When the washing machine is dehydrated, the first locking structure 500 is unlocked, the second locking structure 600 is locked, and the pulsator rotating shaft 300 and the inner tub rotating shaft 400 rotate synchronously, so that the pulsator and the inner tub rotate synchronously, thereby dehydrating. The arrangement of the first locking structure 500 and the second locking structure 600 simplifies the structure of the clutch, reduces the volume of the clutch structure of the washing machine, and increases the height of the inner cylinder; thereby increasing the capacity of the washing machine, enabling the washing machine to wash articles with larger volume and improving the washing efficiency of the washing machine.
