Abstract

A frequency determining portion determines a driving frequency of an induction heater. A determination processing portion determines whether or not the driving frequency determined by the frequency determining portion is within a predetermined prohibited frequency band. A frequency changing portion, when the driving frequency determined by the frequency determining portion is within the prohibited frequency band and is lower than a predetermined threshold within the prohibited frequency band, changes the driving frequency to a frequency equal to or lower than a lower boundary frequency of the prohibited frequency band, and when the driving frequency is within the prohibited frequency band and is equal to or higher than the threshold, changes the driving frequency to a frequency equal to or higher than a higher boundary frequency of the prohibited frequency band. A heating control portion drives the induction heater by the driving frequency changed by the frequency changing portion.
