Abstract

PURPOSE: A dish washer is provided to improve washing efficiency by uniformly spraying washing water into a washing tub. CONSTITUTION: Washing water is supplied to spray arms(17) through a water supply tube(9), and the spray arms rotated in one direction by the pressure of the washing water. Then, the washing water is sprayed toward a basket(13) through many nozzle holes formed in the spray arms. A portion of the washing water supplied to the spray arms is supplied to a propeller nozzle member(20) by passing through a tubular fixing shaft member formed at a free end of the spray arm and sprayed into the basket through spray holes. As the washing water is sprayed in a tangential direction of the propeller nozzle member, rotational force is generated. With the rotational force, the propeller nozzle member rotates by centering on a subsidiary rotary axial line spaced apart from a main rotary axial line. Thus, the washing water is uniformly sprayed into a washing tub.
