Abstract: The cavity is in the case of high temperature and high humidity during the work of the dishwasher, and the inner cavity wall and cutlery are extremely prone to condensation, which is not conducive to dry and cleaning in the dishwasher. For the above phenomena, fluid mechanical analysis and dry experiments are used, and the effects of single wind turbine and double-drying are drying effects on dry and cleaning effects of dishwashers. The results show that the dishwasher uses double fan dry effectively improves the uniformity of the inner cavity wind speed and humidity, and the reduction in humidity is reduced, reducing the condensed water of the inner cavity wall and cutlery.

Key words: Dishwasher, Dual fan system, Simulation analysis, Keep dry
