PURPOSE:To increase the injection torque particularly contributing to washing, and enhance the washing efficiency by setting at least one of first and second washing nozzles into a curved or bent form in the direction delayed to the rotating direction at operation. CONSTITUTION:When dishes are housed in a rack 2, and the rack 2 is installed to a prescribed position of a washing tank 1 to start the operation, water supplying process for supplying a prescribed quantity of washing water to the washing tank 1 is executed. Successively, main washing process for injecting the washing wafer pressurized by a washing pump 3 together with a detergent through a first washing nozzle 6 and a second washing nozzle 7 is executed. Since the second washing nozzle 2 is set into a form bent in the direction delayed to the rotating direction, a sufficient rotating torque can be provided. Therefore, the injection angle of washing water set to an injection hole 8b provided on the second washing nozzle 7 can be raised to contribute to the washing of the dishes. |
