The invention relates to a dehydrator, in particular to a dehydrator capable of being automatically adjusted to a stable state. On the basis of the dehydrator capable of being automatically adjusted to the stable state, a whole hollow cover layer arranged in an original dehydrator body is designed into a hollow cover layer with a center in an annular inner cavity at the periphery of the bottom part, an upper wall and a lower wall in the middle of the hollow cover layer are raised upwards, and the inner cavity at the periphery of the bottom sinks downwards. When the dehydrator capable of being automatically adjusted to the stable state is used to dehydrate clothes, the dangers of relatively large noises, relatively heavy damages on the wall of the inner cavity of the body and a steel ball, and even the puncture of the wall of the inner cavity, caused by the fact that the steel ball in a body cover layer is subjected to high-speed collision with the surrounding under the action of the centrifugal force within a short period of time after the dehydrator starts working, are avoided, and the dehydrator operates more stably and more safely.
