Induction heating cooker and control method thereof
First Claim
1. An induction heating cooker comprising:
- a plurality of heating coil groups, each of the heating coil groups including a plurality of heating coils connected in series;
a plurality of inverters to individually supply high-frequency voltages to the heating coil groups, respectively; and
a controller to control operations of the inverters such that the high-frequency voltages are supplied to the heating coil groups, respectively, based on numbers of heating coils upon which at least one cooking container is placed within the respective heating coil groups.

Abstract
An induction heating cooker and a control method thereof. The induction heating cooker includes a plurality of heating coil groups, each of the heating coil groups including a plurality of heating coils connected in series, a plurality of inverters to individually supply high-frequency voltages to the heating coil groups, respectively, and a controller to control operations of the inverters such that the high-frequency voltages are supplied to the heating coil groups, respectively, based on the numbers of heating coils upon which at least one cooking container is placed within the respective heating coil groups. Therefore, it is possible to effectively heat the cooking container even though the container is put on any position of a cooking plate irrespective of a specific position of the cooking plate. Also, it is possible to effectively heat the container regardless of the size of the container.
