Abstract
A clothes washing machine has a washing water spurting apparatus for spurting washing water directly upwardly from a center of a pulsator. The washing water is guided by at least guide one duct affixed to the pulsator. The pulsator has a plurality of first ribs formed on an underside of the pulsator and second ribs formed in recesses of the lower surface of the underside. Each of the first ribs is spaced a predetermined distance from the inlet of the guide duct. Each of the second ribs has a height extending from the underside of the pulsator, which is smaller than a height of a top border of the inlet. The first and second ribs enable the washing water to flow smoothly into the inlet of the guide duct when the pulsator rotates. The pulsator and the rotating blades are prevented from being deformed by the presence of the ribs.
