Common dish washing machines generally lift water by a water pump and spray the water to fruits and vegetables in a washing space so as to achieve a washing effect, or drive a washing basket to rotate and spray the water into the washing basket from top to bottom so as to rinse the fruits and vegetables in the washing basket. The structure for cleaning fruits and vegetables soaked in water by turbulent flow of water also appears at present.

For example, chinese patent application CN201710714387.0, entitled "a spray arm and a cleaning machine using the same", provides a structure that can cause water flow to turbulence. The water flow turbulence in the fruit and vegetable groove of the dish washing machine is mainly generated by the fixed spray hole jet flow of the fixed spray arm, and a good turbulence effect can be generated in a local area so as to improve the cleaning effect. However, for cleaning fruits and vegetables, a lot of silt and residual leaves are often attached to the surfaces of the fruits and vegetables, the movement mode of pollutants such as fruit and vegetable scraps mainly follows the flow movement, and the sewage port and the residue collection basket in the existing cleaning machine are eccentrically arranged in a draining area at the bottom of the water tank, and the residues are only brought into the residue collection basket through the natural flow of water, so that the pollutants are easy to deposit at the corners of the water tank and are difficult to clean. Pesticide residues often exist on the surfaces of fruits and vegetables, and the common turbulent water flow is not thorough in the aspect of removing the pesticide residues.

In addition, the draining area is used as a water return area and is influenced by the installation mode and the position of functional components at the bottom of the water tank, the volume of the draining area is large, and the water consumption for washing each time is large in order to meet the required water level.
