PURPOSE:In a heating cooker with an infrared detector, to control heat source and to cook food well automatically, by knowing the degree of cooking process of the overall food from the temperature rising properties of the surface of the food under a given condition. CONSTITUTION:An infrared temperature detector, detecting infrared radiation irradiated from food and measuring the surface temperature of the food, is set in a heating cooker, which is heated by the heating power output P1 so that the surface temperature of the food reaches T1 previously set for it. The heating is then stopped, and the cooker is lowered to the set temperature T2. Thereafter heating and suspension are repeated. When the surface temperature of the food is not lowered to the set temperature T3 a fixed time tauf from the suspension, the suspension is continued. When the surface temperature of the food is lowered to T3, the cooker is heated by the second heating power output P2 repeatedly for a total time equal to a time Ktau obtained by multiplying time tau required to make the surface temperature of the food reach from T2 to T1 by the constant K previously fixed empirically depending upon food, or heated continuously for the time Ktau. |
