PURPOSE:To eliminate the striking and abrupt fluctuation in temperature of a heated container, and thereby enhance cooking performance by allowing the output of a charge/discharge circuit to act as the input of the other side, and thereby providing a device with a comparator which changes the output of a control section in such a way that the energizing condition of a switching element is continuously changed. CONSTITUTION:A device is provided with a temperature detecting circuit 12c detecting the temperature of a switching element 10 which controls the quantity of energized electricity to a coil 6 heating a heated container P, and the output of both a charge/discharge circuit 166c which charges/discharges electricity in response to the on/off action of a switching element, and a temperature detecting circuit 12c is made to act as the input of one side. And furthermore, the device is provided with a comparator 168 which makes the output of the charge/discharge circuit 166c to act as the input of the other side, and changes the output of a control section 15 in such a way that energizing condition of the switching element is continuously changed as the switching element is increased in temperature. By this constitution, when the switching element 10 comes close to a critical temperature, the comparator 168 which inputs both of the output of the charge/discharge circuit 166c in a state of charging/ discharging, and the output of the temperature detecting circuit 12c in response to the temperature of the switching element, produces an output in response to both of the output. Heating at which the temperature of the switching element is stabilized, is thereby continuously carried out. |
