ABSTRACT:
Disclosed is a washing machine having a spraying nozzle assembly which evenly and strongly sprays a circulated washing liquid onto an article to be washed. The washing machine has a housing, an outer tub disposed in the housing so as to receive the washing liquid, a spin tub accommodated in the outer tub, an outer tub cover mounted on the outer tub, and a spraying nozzle assembly for spraying the washing liquid onto the article to be washed which is loaded in the spin tub. The spraying nozzle assembly includes an upper frame mounted on an upper surface of the outer tub cover and a lower frame which is rotatably coupled to a lower portion of the upper frame. The lower frame is formed at a bottom wall thereof with a plurality of spraying nozzles which are regularly arranged in a spiral pattern. The washing machine can evenly and strongly spray the circulated washing liquid onto the articles through the spraying nozzles arranged in the spiral pattern, so the washing effect can be improved without wasting any washing liquid. Since the lower frame rotates while the washing liquid is being sprayed, the washing liquid does not concentrate at one spot of the articles, but sprays widely onto the articles.
