Title:
誘導加熱装置およびそれを備えた誘導加熱調理器
Document Type and Number:
Japanese Patent JP5662344
Kind Code:
B2
Abstract:
An induction heating apparatus according to the present invention includes: an inverter circuit (40) which outputs an AC signal through ON and OFF operations of a plurality of switching devices (46, 47); a control portion (52) which drives and controls the plurality of switching devices; and a plurality of resonant circuits (56, 57) which includes respective resonant capacitors (50, 51) and respective heating coils (48, 49) for inductively heating an object to be heated; wherein the switching devices are driven and controlled, by using, as an operating range, a frequency range higher than a highest resonance frequency, or a frequency range lower than lowest resonance frequency, out of respective resonance frequencies of the plurality of resonant circuits, and the respective heating coils in the plurality of resonant circuits are combined to form at least a single induction heating source.
