To attain the finish state of laundry equal to or close to the one when it is dried without performing a drying step even if washing, a rinsing step and the drying step are performed all the way through.
Regarding the drive of a rotary drum 4 whose rotary axis direction is made horizontal or inclined downwards from the horizontal direction from the open front surface side to the back surface side to be a bottom part, the forward and reverse arc rotary drive mode of alternately repeating rapid forward arc rotation and rapid reverse arc rotation over 90 degrees and less than 200 degrees is performed alternately with the forward and reverse continuous rotary drum mode of alternately repeating the forward and reverse continuous rotation at such a rotation speed that laundry lifted by the rotation of the rotary drum 4 shows the action of falling from the height at which its gravity is superior. In the through performance from the washing step to the drying step, the performance ratio of the forward and reverse arc rotary drive mode to the forward and reverse continuous rotary drive mode in the washing step or in the washing and rinsing step is made higher than that in the case of washing only.
