Abstract

PURPOSE:To effectively prevent an ignition without influence of a material, etc., of a pan when deep-fried food such as 'tempura', etc., is cooked by controlling heating means only by weak heating power only for a predetermined time by a control circuit when a detected temperature reaches a preset set temperature if setting of heating power regulating means is strong heating power. CONSTITUTION:If a cooking of deep-fried food is, for example, started by strong heating power, when a temperature of the food to be cooked reaches a predetermined temperature, heating power of a burner 2 is forcibly reduced to weak heating power for a predetermined time. Thus, a temperature difference between a detecting temperature of a temperature sensor 10 and a temperature of oil due to influence of a material of a pan, oil amount, etc., is reduced, and particularly natural ignition at the time of cooking due to a small quantity of oil can be prevented. The burner 2 can be effectively altered from strong heating power to weak heating power, and the weak heating power to weak heating power by regulating the power of the burner 2 by a motor valve to be driven by a motor.
