PROBLEM TO BE SOLVED: To provide a drum-type washing machine capable of yielding stable rinsing performance with low vibration.SOLUTION: A washing machine includes: a rotary drum 3 freely rotatably disposed inside a water reception tank 2; a motor 4 for driving the rotary drum 3; vibration detection means 25 for detecting vibration of the water reception tank 2; a circulation route 9 for suctioning washing water from the water reception tank 2, the water contained therein, ejecting the water into the rotary drum 3 and circulating the water therein; a circulation pump 10 disposed in the circulation route 9; and control means 14 for controlling the number of revolutions of the motor 4 and circulation pump 10 to control the respective steps of washing, rinsing and dewatering. Further, in an intermediate dewatering step of the rinsing step, the control means 14 increases the rotation speed of the rotary drum 3 in a stepwise manner, drives the circulation pump 10 to circulate the washing water and decreases the rotation speed of the circulation pump 10 in a stepwise manner in the case of a vibration value of the water reception tank 2 exceeding a predetermined value. This configuration makes it possible to yield stable rinsing performance with low vibration and low noise. |
