A Study on Stirrer of K23L Flat Microwave Oven

Promotion of the flat microwave oven center filed plays an extremely important role in improving the microwave oven cooking performance,and the overall quality of the microwave oven.The K23L flat microwave oven has good distribution uniformity of electromagnetic field,however,the field in center of ceramic plate is too low,as well as the cooking performance.First of all,the stirrer is found to play an important role on affecting the performance of flat microwave oven after simulating electromagnetic properties of K23Lflat microwave oven with the electromagnetic software HFSS.Besides,a new stirrer is presented to enhance the K23L's center field and cooking performance with the simulation analysis by HFSS and experiments verification.Studies show that new stirrer improve the cooking performance by 4.5%, and as well as the output efficiency by 2%around.
