Abstract: Drying performance is one of the basic indicators of dishwasher. Analyzes the fan drying technology and its system commonly using in dishwashers, and sums up the problems including fixed air flow state, uneven drying efficiency, insufficient condensation of exhaust gas, etc. Then it puts forward the air inlet and exhaust two-way ventilation technology including double fans mixing condensation technology, which realizes the integration of air inlet mode and exhaust mode through the switchable air duct design and the combined use of double fans. In the exhaust mode, through the mixing condensation in the air duct, the moisture content of the exhaust air is effectively reduced, so as to solve the problem of "dishwasher outlet condensate". Furthermore, designs the two-way ventilation system with double fans and the multi-mode ventilation system with multi-fans. Inside the dishwasher chamber, there forms the continuously changing air flow, which can achieve the even drying efficiency everywhere and the better drying performance.
