Abstract:
1. An induction heating cooking apparatus comprising: a load driving unit to drive a working coil heating a container; a receiving unit to receive a demand response (DR) level related to power rate information; a storage unit to store output levels of individual DR levels; and a controller to confirm an output level corresponding to the DR level received through the receiving unit, change an output level established in the working coil to the confirmed output level, and control an operation of the load driving unit in such a manner that the working coil is operated at the changed output level, wherein the demand response level is established by a demand response (DR) control unit which receives power rate information from a power company to establish DR levels representing different power rates using the received power rate information, wherein the stored output levels in the storage unit are equal to initial output levels when the received DR level is a lowest possible DR level, and wherein the stored output levels in the storage unit are values which are decreased from the initial output levels by an amount corresponding to the difference between the received DR level and the lowest possible DR level to a minimum of a lowest possible initial output level, when the received DR level is not the lowest possible DR level.
