Abstract

A washing machine includes an inner tub assembly for accommodating laundry, a pulsator rotatably provided to an inner lower portion of the inner tub assembly, a blade installed at a lower portion of the pulsator to be rotatable independently from the pulsator, the blade being configured to pump wash water to raise the wash water to an upper end of the inner tub assembly, a drive motor for providing rotational power to the pulsator and the blade, and a power transmission unit for transmitting power of the drive motor to the pulsator and the blade, respectively. The power transmission unit includes a first planetary gear module for transmitting a rotational speed of the drive motor to the pulsator by decreasing the rotational speed, and a second planetary gear module for transmitting the rotational speed of the drive motor to the blade by decreasing the rotational speed.
