<p><P>PROBLEM TO BE SOLVED: To provide an induction heating cooker capable of reducing interference sound even if interference sound is generated between heated objects due to the difference of operating frequencies between heating coils. <P>SOLUTION: The induction heating cooker is provided with a microphone 18 for collecting interference sound generated between heated objects 21 which are induction heated by three heating coils 3, 4, 5, respectively, and an interference sound control part 17a inputting an electric signal from the microphone 18 at the time of heating operation of at least two heating coils among the three heating coils 3, 4, 5, detecting a frequency and a phase of the interference sound from the electric signal, generating an electric signal for offsetting the interference sound from the frequency and the phase, and outputting it to a speaker 19 to have sound generated. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
