Title:
An induction-heating cooking device and a method for controlling the same
Document Type and Number:
Japanese Patent JP6021516
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an induction heating cooker capable of finely adjusting a predetermined heating power depending on a heating power desired by a user.SOLUTION: An induction heating cooker comprises:a plurality of heating coils and power supply parts; a detection part calculating a load resistance and a resonance frequency; an operation part by which a desired target heating power can be set; and a controller. The controller a) determines a frequency obtained by adding a predetermined difference frequency corresponding to the desired target heating power for each heating coil, which is set by the user, to the maximum resonance frequency of the calculated resonance frequencies of the respective heating coils, as a drive frequency, and b) controls each power supply part so as to adjust a time interval for periodically supplying a high-frequency current having the determined drive frequency to each heating coil, on the basis of the desired target heating power of each heating coil, which is set by the user, and the calculated load resistance of each heating coil.
