The washing machine adapts water bath type air bubble washing, the washing effect through the air bubble release in the water let the material do irregular strong turnover movement, via the movement of the material can efficiently separate the surface adhesive impurity, simulating manual basic washing action at the same time because the turnover movement in the air-water  mixture can efficiently avoid the touch, crash and scratch damage to the material, improving working efficiency, changing manual work into mechanized processing. Suitable for fresh fruit, vegetable and mushroom. This washing machine add spray washing function in the convey process to let the material go through with the spray wash after the air-water mixture cleaning process, the function of this process is replacing the dirty water on the material surface to improve the washing effect. At the same time the new adding spray water will flow into the water tank after washing the the material to replace the dirty water in the washing tank so that can maintain the cleanness of the washing water which both improve the use ratio of water and add the cleaning effect.
