Abstract
An induction heating cooker includes a plurality of heating coils to heat a container, an inverter having a plurality of switching elements to be operated such that a high-frequency voltage is selectively supplied to the plurality of heating coils, and a control unit to control the operations of the plurality of switching elements such that the high-frequency voltage is time-divisionally supplied to a heating coil, on which the container is positioned, among the plurality of heating coils. By this configuration, it is possible to reduce the number of inverters and manufacturing costs. In addition, since the thickness of the cooker is reduced, it is possible to reduce the overall size of the cooker.
