Efficient energy-saving drying system for dish washing machine and control method of efficient energy-saving drying system

Abstract

The invention belongs to the technical field of dishwashers, and discloses an efficient energy-saving drying system for a dishwasher and a control method thereof.A breathing opening and a ventilation opening are formed in the two sides of a shell respectively, a spraying arm is arranged at the bottom of a cavity of the dishwasher, and a temperature detector, a humidity detector and a pressure detector are installed on the inner side of an inner container; the air channel is clamped between the shell and the inner container, the two ends of the air channel are communicated with the ventilation opening and the inner container respectively, and a fan and a PTC heating device are arranged in the air channel. The reversible axial flow fan and the PTC heating device are controlled through temperature and humidity signals, wet steam in the dish-washing machine can be effectively sucked through reverse rotation of the fan, and the good drying effect is achieved. The problems that in the drying process of a traditional dish washing machine, a PTC heating device and a draught fan operate for a long time, heat loss is large, drying time is long, and the energy utilization rate is low are solved. The drying efficiency can be improved, the drying time is shortened, and the purpose of improving the performance of the dish-washing machine is achieved.

Description

technical field [0001] The invention belongs to the technical field of dishwashers, and in particular relates to a high-efficiency and energy-saving drying system for dishwashers and a control method thereof. Background technique [0002] At present, with the improvement of living standards and the popularization of household appliances, dishwashers have begun to be widely used in daily life. At present, the drying methods used in dishwashers mainly include condensation drying, cold air drying, hot air drying, and automatic door opening drying. Condensation drying is to evaporate the water on the dishes through the residual temperature after washing the dishes. The drying speed is slow and the drying effect is not good, which will cause the cavity of the dishwasher to be wet; The wet steam inside the dishwasher is taken away, and the drying effect is poor; the automatic door drying relies on hot and cold air convection for drying, and the drying speed is fast, but the exter...

AI Technical Summary

Problems solved by technology

[0004] The drying time of the existing drying system for dishwashers is long and the energy utilization rate is low, and the drying temperature and duration cannot be intelligently adjusted according to the type and quantity of dishes in the dishwasher, resulting in poor drying effect and time-consuming energy consumption

[0005] The difficulty in solving the above problems and defects is: due to the obstruction of the internal structure of the dishwasher and the obstacles of dishes and chopsticks, the circulation of hot air in the dishwasher cavity is poor, and the wet steam is not easy to be discharged from the breathing hole

The hot air drying method currently used in the market has no effective solution to this problem, and solving this problem becomes the key to improving the drying efficiency of the dishwasher
