ABSTRACT:
An electromagnetic induction heater in which magnetic flux diffusing members are fixed to at least two ends of an iron core wrapped with an electric wire to form a coil, and a metal plate is connected to the magnetic flux diffusing members to heat a wide area of the metal plate uniformly. By supplying a commercial low frequency alternating power source of 50-60 Hz to the coil, magnetic flux is generated in the iron core. The magnetic flux, flowing in the magnetic flux diffusing members, is diffused in a longitudinal direction. Diffused magnetic flux flows through the metallic plate to generate Joule heat over the plate. Therefore, the entire surface of the metal plate is heated uniformly. Either a single-phase or three-phase alternating power source is used in this invention.
