ABSTRACT:
A spraying nozzle assembly for a dishwasher which can widely spray a washing liquid toward utensils. The spraying nozzle assembly has an adapter fixedly connected to a washing liquid outlet of a pump, a rotary spray arm which is rotatably coupled to an upper portion of the adapter and receives a washing liquid from the pump through the adapter, a spraying nozzle for spraying the washing liquid introduced into the rotary spray arm toward utensils, and a spring assembly which is coupled to the spraying nozzle and allows the spraying nozzle to be moved in such a manner that the direction of the washing liquid being sprayed therefrom is varied. The spring assembly is coupled to a fixing shaft which is eccentrically disposed with respect to a rotating axis of the rotary spraying arm. The spraying nozzle assembly can spread the spraying range of the washing liquid being sprayed, so the utensils can be effectively washed and wasting of the washing liquid can be reduced.
