PURPOSE: A washing machine for making two fluids of water and air and then ejecting them into a washing tank using a specially fabricated ejector is provided, thereby achieving washing by a symmetric turbulent flow and air bubbles, and controlling the washing time in each step. CONSTITUTION: A washing machine comprises a first washing tank(1) for prewashing an object to be washed and a second washing tank(2) installed at the end part of the first washing tank. The second washing tank contains: a plurality of transfer nozzles(23, 33); and a plurality of ejectors. A conveyor belt(42) is installed to transport the object to be washed.
