Abstract
A clothes washing machine has a washing water spurting apparatus for spurting washing water directly upwardly from the center of a pulsator. The washing water spurting apparatus has at least one guide duct and a spurt cap. The spurt cap has a canopy forming a spurt hole. The canopy has a core and an arcuate rim surrounding the core, between which the spurt hole is formed. The core has ribs extending from the core toward a cylindrical inner surface of the arcuate rim. Distal ends of the ribs are spaced a predetermined distance from the cylindrical inner surface. The ribs increase a spurting pressure of the washing water and prevent foreign materials from entering the guide duct downwardly through the spurt hole.
