Background

Washing machines are largely classified into pulsator type, pulsator type and drum type washing machines. The pulsator type washing machine performs a washing operation by rotating a pulsator at the center of a washing tub left and right. The agitator type washing machine performs a washing operation using a frictional force between water current and laundry by rotating a rotary blade at the center of a washing tub in the left-right direction. The drum type washing machine performs a washing operation by beating laundry by rotating a drum.
