INDUCTION HEATING DEVICE AND HEATING SYSTEM EQUIPPED WITH SAME

摘要

Provided are: an induction heating device which cannot be broken upon the irradiation with microwave or during the use at a higher temperature; and a heating system equipped with the induction heating device. The induction heating device (1) comprises: a ring-shaped electrically conductive body (2) which is composed of an electrically conductive material such as a metal having low electrical resistance, such as aluminum and copper; a coil (3) which is formed by winding a coated copper wire several times; a magnetic body (4) which is so arranged that a high-frequency magnetic flux that is generated upon the conduction of a high-frequency current to the coil (3) can form a magnetic circuit that interlinks with the ring-shaped electrically conductive body (2); and a high-frequency power supply (5) which can supply a high-frequency current to the coil (3). The ring-shaped electrically conductive body (2) comprises a heating unit (25) adjacent to which an object (6) to be heated is placed and a power supply unit (24) at which the high-frequency magnetic flux that has been generated by the coil (3) interlinks, and the magnetic body (4) is so arranged that high-frequency magnetic flux generated by the coil (3) can interlink at the power supply unit (24) in the ring-shaped electrically conductive body (2).
