TECHNICAL FIELD

The embodiments of the disclosure relate to the technical field of dehydration, and in particular to a method and apparatus for washing machine dehydration, and a washing machine.

BACKGROUND

When an existing washing machine washes a small load of clothes having good water absorbability, a condition in which the water is not dehydrated or the water cannot be dehydrated completely is occurred. For example, one or two sweaters absorb a large amount of water after washing and a small amount of clothes cannot be uniformly distributed in a roller, so that an eccentricity value is very high and the washing machine cannot enter dehydration. Even though the washing machine enters the dehydration, due to the very high eccentricity value, a dehydration rotational speed is low and thus the clothes cannot be dehydrated completely.

Concerning the problem of a poor dehydration effect when the washing machine washes the small load of clothes having the good water absorbability in the conventional art, an effective scheme hasn't been proposed till now.
