PURPOSE:To set the optimal heating quantity by detecting a highly precise amount of boiling rice. CONSTITUTION:The application of an electric current to a rice-cooking heater 15 is stopped during the immersion and cooking of the rice to dispose a heating- stopping period. A rice-cooking quantity is determined on the drop in the temperature of a container sensor 18 and on the temperature of water at the early time during the period. The change in the temperature of the container sensor 18 is detected, when the application of the electric current applied to the rice- cooking heater 15 is stopped after the control of the heating. On the change in the temperature, the quantity of the heating in the second stage of the stabilization control is corrected by changing the current application degree of the rice-cooking heater 15. The detection of the temperature with the container sensor 18 can precisely be performed without being affected by the heat of the rice-cooking heat 15. Since the detection of the temperature is performed several times, a judgment error caused by the irregular contacts of the container with the container sensor 18 can be corrected. |
