Abstract
A low-frequency electromagnetic induction heater includes a plurality of leg iron cores, a corresponding yoke iron core arranged on the leg iron cores, an induction coil wound around each leg iron core, and an iron plate or metal vessel for producing Joule heat with which the leg iron cores or induction coils are substantially in direct contact. The spaces between the yoke iron core, the leg iron cores and the induction coils are solidly filled with a resinous substrate which has been molded using molten resin. The induction heater produces less noise than other such heaters while providing a higher level of electromagnetic flux density.
