(54)Washing machine and control method thereof


(57) A washing machine and a control method thereof in which laundry is washed in a state of being directly heated by steam. The washing machine includes a microcomputer (61) for controlling the overall operation of the washing machine to wash laundry by using steam. The microcomputer controls operations of wetting (130) laundry with a small amount of water prior to generation of steam, uniformly spraying (160) detergent over the wet laundry, and injecting (190) steam onto the laundry. Accordingly, it is possible to achieve a reduction in the amount of water to be used and a reduction in wash time while preventing the laundry from being stained or damaged during the wash operation using steam.
