Sistema de cocción por calentamiento por inducción

摘要

An induction-heating cooking system according to one embodiment of the present invention includes a central coil convolved in a planar configuration, a plurality of peripheral coils arranged around said central coil, and a plurality of inverter circuitries for supplying high-frequency current to the central coil and each one of the peripheral coils individually. It also includes detecting means for detecting a standing situation of a heated body set over the central coil and the peripheral coils, and a drive controller adapted to control the inverter circuitries so that the central coil and each one of the peripheral coils are selectively supplied with the high-frequency current based upon the standing situation of the heated body. Therefore, according to the induction-heating cooking system of one of the embodiments, upon detecting the standing situation (various sizes and profiles as well as deviated standing positions of the pan P), the central coil and the peripheral coils are used to effectively heat the pan and suppress undesired magnetic filed which makes no contribution for heating the pan.
