<p><P>PROBLEM TO BE SOLVED: To provide an induction heating device that can control heat distribution while improving heating efficiency when heating a pan smaller than a diameter of a heating coil. <P>SOLUTION: An induction heating device includes has a plurality of resonance circuits 56, 57 where heating coils 48, 49 to perform induction-heat a substance to be heated are disposed, and are parallely connected to an inverter circuit, which is actuated with frequency domain higher than the highest resonance frequency out of the resonance frequencies that the plurality of resonance frequencies have, and in the frequency domain in which a switching element is actuated, values of at least inductance of the heating coil and capacitance of a capacitor are set so that the values are power distribution to perform the induction-heating of the substance to be heated in all of the heating coils of each of the plurality of resonance circuits in the frequency domain where the switching element is actuated. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
