The invention discloses a washing machine and a control method thereof. The method comprises the following steps: obtaining the weight of the to-be-washed things in an inner bucket of the washing machine; obtaining the target water feeding times and the target spin-drying times according to the weight of the to-be-washed things; and controlling a drive component and a water feeding component of the washing machine according to the target water feeding times and the target spin-drying times during the rinsing of the washing machine, wherein the washing machine drives the inner bucket to rotate through the drive component and feeds water into the inner bucket through the water feeding component. By feeding a small quantity of water for rinsing and greatly prolonging the spin-drying time, an effect of removing washing residues is realized, and the rinsing water quantity is reduced while the rinsing effect is guaranteed.
