PROBLEM TO BE SOLVED: To provide a washing machine which solves twisting of laundry and which improves washing performance.SOLUTION: A washing machine includes: a plurality of water flow forming ribs 28 provided on an upper surface of a pulsator 18 in a radially protruding manner; auxiliary ribs 29 provided between the adjacent water flow forming ribs in a radially protruding manner; and control means for controlling a motor 20, a water supply valve 41 and the like and for sequentially controlling a series of steps of washing, rinsing and dewatering. The pulsator 18 forms the auxiliary ribs 29 on the outer peripheral side, forms rotation water flow roller installation parts 30 on the inner peripheral side of the auxiliary ribs 29. In the rotation water flow roller installation part 30, a rotation water flow roller 31 is mounted rotatably in which a plurality of roller ribs 42 are provided in a radially protruding manner on the upper surface. Thus, by a water flow generating from the outer peripheral part of the pulsator 18 and a water flow generating from the central part, laundry is agitated and twisting is prevented, so that washing performance can be improved, and the pulsator 18 becomes cheap and highly reliable in a configuration aspect as well. |
