摘要

It accurately detects the state of the object to be heated in the cooking vessel, to prevent more effectively the failure of cooking. The induction heater 13, the induction heating cooking container 11, the vibration detector 14 detects vibration of the cooking container 11 through the top plate 12, the vibration waveform extracting unit 15, detected by the vibration detector 14 from the vibration waveform, and to extract the vibration waveform of a frequency component corresponding to a predetermined multiple of the induction heating frequency, based on the vibration waveform extracted by the vibration waveform extracting section 15, the determination unit 16 determines the state of the object to be heated .
