Summary:In the present invention, when causing a first and second inverter circuit (3, 4) to both operate, a control unit (8) controls the first and second inverter circuits (3, 4) by means of duty control in a manner so that the average heating output of the first and of the second inverter circuit (3, 4) respectively become a predetermined first and second target heating output, and when causing one inverter circuit of the first and second inverter circuits (3, 4) to operate in an automatic heating mode for performing automatic heating control in accordance with a predetermined heating output sequence, the control unit (8) forbids control by means of duty control of the first and second inverter circuits (3, 4).
