Title:
誘導加熱装置
Document Type and Number:
Japanese Patent JP5794635
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To switch power supply in a short time while reducing electromagnetic effects between both coils, by reducing mutual inductance between a central coil and a plurality of unit peripheral coils arranged contiguously thereto on the periphery thereof.SOLUTION: The induction heating apparatus heats a heated object by conducting a high frequency current through a heating coil thereby generating an eddy current in the heated object. The heating coil consists of a central coil 1 arranged so that the central axis is orthogonal to the bottom face of the heated object 6, and a peripheral coil 2 formed by connecting a plurality of unit peripheral coils 2a-2l, arranged uniformly on the same plane as the central coil 1 on the periphery thereof, in series so that the current direction of each coil is identical at a part adjacent to each other. AC power is supplied alternately to the central coil 1 and the peripheral coil 2 by time sharing.
