Claim of US Patent No. 10,364,521

1. A method of operating a washing machine having a pulsator rotatably provided in a tub, the method comprising:a divisional rotation mode having:
a first divisional rotation process of rotating the pulsator with a first end angle in one direction around a rotation shaft; and
a second divisional rotation process of rotating the pulsator with a second end angle in the other direction around the rotation shaft, wherein the first end angle is greater than the second end angle,
wherein the first divisional rotation process divides the first end angle into at least two angles to rotate the pulsator in the one direction, and
wherein the second divisional rotation process divides the second end angle into at least two angles to rotate the pulsator in the other direction,
wherein the first divisional rotation process includes suspending the pulsator between the two divided angles of the first end angle, and the second divisional rotation process includes suspending the pulsator between the two divided angles of the second end angle.
