The invention also provides a washing machine, which is provided with the inner barrel and specifically comprises the following components:
as another embodiment of the present invention, the present embodiment provides a washing machine, which has the inner tub as described in the first embodiment, and further includes a motor, a pulsator shaft, and a pulsator.
In this embodiment, the motor is located below the inner tub, the pulsator is located inside the inner tub, and the pulsator shaft extends upward from the inside of the motor and is connected to the pulsator through the through hole of the inner tub.
When the washing machine generates eccentricity, the balance medium in the balance device between the bottom of the inner barrel and the bottom cover of the inner barrel moves to the other side opposite to the eccentric side under the action of centrifugal force, and the eccentricity of the washing machine is corrected.
The balance cavity and the buoyancy cavity have larger spaces, and buoyancy can be provided for the inner barrel, so that the washing machine can realize buoyancy clutch, the complexity of the internal structure of the washing machine is reduced, and the miniaturization of the washing machine is realized.
The above embodiments are only preferred embodiments of the present invention, and not intended to limit the present invention in any way, and although the present invention has been disclosed by the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make various changes and modifications to the equivalent embodiments by using the technical contents disclosed above without departing from the technical scope of the present invention, and the embodiments in the above embodiments can be further combined or replaced, but any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention still fall within the technical scope of the present invention.
