PROBLEM TO BE SOLVED: To provide a vertical-type washing machine employing a pulsator-type rolling-mode washing method.;SOLUTION: Rolling for lifting, casting, dispersing and dropping laundry is performed by protruded rib-like blades on a pair of pulsators 6 and 8 arranged so as to be inclined, and is repeated while the rotation directions of the pulsators are changed. Further, auxiliary force is applied to the side face of the laundry by at least one pulsator 7, and thereby the employment of a rolling-mode washing method in multiple directions remarkably improves laundry washing power and remarkably improves the possibility of the position change of the laundry between an inner side and an outer side. As a result, a rolling effect better than that in a drum-type washing machine is obtained in a vertical-type washing machine. In addition, a method for balancing the vertical-type washing machine is employed, so that: the difficulty of balance control during high-speed rotation is significantly reduced; the drawbacks of the drum-type washing machine and a pulsator-type washing machine are overcome; the advantages thereof are utilized; and an advantage greater than the simple combination thereof is provided.;COPYRIGHT: (C)2016,JPO&INPIT
