Abstract:
The present invention relates to a washing machine, and more specifically to a drum washing machine allowing a tub to be easily cleaned, and to a method for cleaning the tub of the drum washing machine. To that end, the present invention, with respect to a method for controlling a washing machine comprising washing and rinsing cycles, provides a method for controlling the washing machine comprising: a first water supplying step for supplying washing water to the interior of a tub while a drum is rotating at a water-supplying RPM; and a first wash step, executed following the completion of the first water supplying step, for accelerating the rotation of the drum from the water-supplying RPM to first-wash RPM so that a circulatory flow is created in which the washing water falls from the top of both ends of the tub while circulating along the inner circumferential surface of the tub due to the rotational power of the drum.
