<p>A drum-type washing machine includes a casing, a washing tub, a drum, a motor, a vibration detector, a frequency component calculator, and a controller. The drum with an agitating protrusion on its inner peripheral wall is placed in the washing tub for containing a laundry. The vibration detector detects vibration acceleration of the washing tub. The frequency component calculator calculates a frequency component in the vibration acceleration detected by the vibration detector. The controller controls a forward- reverse continuous pivot drive mode, and also determines the state of laundry in the drum during washing or rinsing, based on a result received from the frequency component calculator.</p> |
