<p><P>PROBLEM TO BE SOLVED: To obtain an induction heating cooker which can be controlled so that a drive frequency of a driving circuit for driving each heating coil becomes a frequency in the phase delay region higher than a resonance frequency in a configuration including a plurality of heating coils. <P>SOLUTION: Based on increase/decrease in an output voltage occurring when the drive frequency of the driving circuit is increased or decreased, a control means detects whether or not the drive frequency is the frequency in the phase advance region lower than the resonance frequency, and when the drive frequency is the frequency in the phase advance region 16, the control means controls the driving circuit so that the drive frequency becomes the frequency in the phase delay region 15 higher than the resonance frequency. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
