With the improvement of People＇s expectation for household appliances, intellectualiza-tion has become the inevitable trend of their development. Until now, intelligent household ap-pliances have been able to realize the improvement of their added value. Based on describing de-signed performances of electronic oven timer as well as investigation and analysis, this paper puts forward design scheme for hardware circuit of intelligent electronic oven control, analyzes the working principles of hardware circuit and introduces each circuit module. Meanwhile, it designs printed circuit board of timer and instruction assembly. Through debugging verification we find that the timer can meet actual working performance requirements.
