<p>[Solution] A main heating coil, a plurality of flat-shaped sub-heating coils that are arranged around the main heating coil, inverter circuits that supply induction-heating electric powers to the main heating coil and the sub-heating coils, and a conduction control circuit that issues to each of the inverter circuits a conduction pattern corresponding to a cooking menu are included. The conduction control circuit has at least a "water-boiling mode" and a "boiling mode" as a cooking mode that can be selected by a user. In the case where the target object is heated in the "water-boiling mode" and the "boiling mode", the conduction control circuit is capable of automatically determining heating only by the main heating coil or heating by the main heating coil and the sub-heating coils in cooperation with each other. In the "boiling mode", the conduction control circuit automatically determines the heating power ratio of the main heating coil to the sub-heating coils, and performs a conduction pattern in which driving for heating is repeated at specific time intervals.</p> |
