<p>PROBLEM TO BE SOLVED: To make it possible to start heating operation without waiting for operation of a blower fan without increasing a temperature in a main body to improve convenience.SOLUTION: An induction heating cooker comprises a blower fan 20, control means 19, rotation speed detection means 20b detecting a rotation speed of the blower fan 20, and a main power supply switch 9d that powers on/off the control means 19. The control means 19 is provided with a main control circuit 190a outputting a motor control signal Md so as to reach a target rotation speed of the blower fan 20, and a motor drive circuit 190b generating a voltage corresponding to the motor control signal Md to supply the voltage to the blower fan 20. When the main power supply switch 9d is turned on, the target rotation speed is set to the lowest rotation speed, and then, the blower fan 20 is driven. The rotation speed detected by the rotation speed detection means 20b is inputted to the main control circuit 190a and the motor drive circuit 190b to control a voltage generated from the motor drive circuit 190b so as to reach the target rotation number.</p> |
