<P>PROBLEM TO BE SOLVED: To control an induction heating type heat source even having different heating control by using a control method for a turn-on/off type heat source. <P>SOLUTION: When switching to the control of an IH heater based on a switching instruction from a temperature control part 12, a heater control part 14 converts a heater turn-on rate received from the temperature control part 12 into PWM-Duty being the rate of pulse width given to the IH heater 17 relative to maximum pulse width equivalent to the rate of power consumption to the maximum power consumption of the IH heater 17, and sets the PWM-Duty to the IH heater 17. The IH heater 17 controls the temperature thereof so as to reach the predetermined temperature, by linearly changing the amount of current applied thereto based on PWM-Duty set from the heating control part 14. <P>COPYRIGHT: (C)2007,JPO&INPIT |
