Abstract
A first positioning structure is arranged at the bottom of the inner tub of a washing machine, and a second positioning structure is arranged at the bottom of the outer tub. When the two positioning structures come into concave-convex cooperation, the inner tub is locked; and when the two positioning structures separate from each other, the inner tub is unlocked. A locking hole is formed at the bottom of the inner tub; a stretchable and contractible locking rod is arranged at the bottom of the outer tub; when the locking rod projects into the locking hole, the inner tub is locked; and when the locking rod separates from the locking hole, the inner tub is unlocked. During washing, the inner tub is locked without water between the inner tub and the outer tub.
