PURPOSE:To perform the optimum rice cooking with low heating nonuniformity by providing a control circuit which selects high frequency current capacity higher or lower than a requested high frequency current to be supplied from an inverter circuit to a heating coil successively corresponding to the output signal of a rice cooking quantity detecting means and that of a temperature detecting means. CONSTITUTION:This rice cooker is provided with the heating coil 5 to heat by inducing an inner pot 2, the inverter circuit 8 which supplies the high frequency current to the heating coil 5, the control circuit 3 which controls the inverter circuit 8, a bottom temperature detector 21 which detects the temperature of the inner pot 2, and a cover temperature detector 23 which detects the temperature of an outer cover. The rice cooking quantity is judged by the temperature rise ratio of bottom temperature and cover temperature while heating by high heating is being applied in cooking, and an appropriate low heating power is set corresponding to the rice cooking quantity after boiling. Thence, when the bottom temperature is steeply increased as reducing a water component in the inside and approaching the completion of rice cooking and temperature arrives at rice cooking completion temperature, a stroke is transferred from a rice cooking stroke to a steaming stroke. |
