INDUCTION HEATING DEVICE AND HEATING DETERRENCE METHOD BY LEAKAGE FLUX OF HIGH-FREQUENCY CURRENT

摘要

PROBLEM TO BE SOLVED: To provide an induction heating device aimed at uniformalizing temperature distribution of a heated object in induction heating the same. SOLUTION: The induction heating device for heating a heated object by inducing overcurrent to the heated object by supplying induction coils with high-frequency current is so made to reverse a direction of current by crossing more than once the induction coils and power-feeding sites where high-frequency current is supplied to the induction coil, whereby, the induction coils can be arranged in opposition to each other with a given interval, at which time, the crossing sites of the induction coils arranged in opposition with the given interval are to be arranged in opposition to each other.
