When the washing machine is dehydrated, water in the inner barrel 2 is thrown out through the dehydration holes 13 and enters a closed area between the inner barrel 2 and the box body 1, and most of the thrown water flows down along the inner wall of the box body 1 and enters the fixed chassis 4 and then is discharged out of the washing machine through the water discharge port 11 and the water discharge pipe 12. A small amount of water may be sprayed to the outer wall of the inner tub 2, which is relatively clean water after rinsing the laundry, and the amount of water is small, so that dirt is not substantially remained on the outer wall of the inner tub 2, the tidiness between the inner tub 2 and the cabinet 1 is maintained, and secondary pollution is avoided.
When the driving device 3 drives the inner barrel 2 to rotate, the inner barrel 2 and the fixed chassis 4 vibrate due to eccentricity caused by uneven distribution of clothes.

In the manner of dynamic sealing of the suspension damper assembly 5 and the flexible connecting device 6 of the present embodiment, the suspension damper assembly 5 and the flexible connecting device 6 can perform relative up and down movement and maintain sealing. Therefore, when the suspension damper assembly 5 moves up and down due to the vibration of the washing machine, the flexible connecting device 6 does not move along with the suspension damper assembly 5, and the damage to the flexible connecting device 6 can be avoided. Flexible connection device 6 itself still has the deformation allowance to with 1 circumference of box all sealed settings, can also play certain shock attenuation cushioning effect on each direction, both cooperations, the shock attenuation effect that reaches is also better.
