The present invention belongs to the technical field of washing machines, and discloses a washing
machine and a control method thereof. The washing
machine includes an inner tub, and an eccentric member is provided on the wall of the inner tub. The eccentric member can absorb water to increase its weight, and can lose water to reduce its weight when the rotation speed of the inner tub is greater than a set rotation speed V0. By providing an eccentric member on the wall of the inner tub that can absorb water to increase its weight, when the washing
machine washes small loads, the eccentric member that has absorbed water and increased its weight can offset at least part of the eccentricity generated by the load in the tub after draining, enabling the inner tub to reach a balanced state and thus start
dehydration. At the same time, during the
dehydration process, when the rotation speed of the inner tub is greater than the set rotation speed V0, the eccentric member
dewatering synchronously with the load maintains the balanced state of the inner tub, ensuring the smooth progress of the
dehydration process.
