Abstract: A washing machine that performs a washing course by heating wash water and a control method thereof are provided. The method includes supplying wash water up to a wash water level for generation of steam such that a portion of laundry received in an inner tub is saturated by the wash water. The wash water level may be above a bottom surface of the inner tub and below a wash water level for main washing. The method then includes heating the wash water to a first set temperature and driving a washing heater to generate steam from the wash water, and supplying the generated steam to the inner tub, and then supplying the wash water up to the wash water level for main washing, and driving the washing heater again to heat the wash water to a second set temperature, the second set temperature being lower than the first set temperature.

Abstract: In a control method of a washing machine, a washing operation is performed through a heating washing process for a first set time and is performed through a non-heating washing process for a residual time, and, if the heating washing process is started, the rotation of a driving motor is weakly controlled until a washing water temperature reaches a primary target temperature, and is strongly controlled until the washing water temperature reaches a secondary target temperature after the washing water temperature reaches the primary target temperature, so that the washing water temperature is relatively gradually increased.

Abstract: A washing method includes (a) continuously rotating a drum in one direction at a first speed such that laundry is lifted to a predetermined height and then falls, (b) accelerating the drum to rotate the drum at a second speed such that the laundry is moved in a state in which at least some of the laundry clings to the drum, and (c) spraying wash water into the drum during rotation of the drum at the second speed.
