The present invention provides an induction heating device which can prevent the increase of overall weight of the device and does not over-heat the edge of heated object. The induction heating device of the invention performs induction heating to a heated object through supplying high-frequency current to heating coils. The induction heating device comprises the following components: a first heating coil which is supplied with a high-frequency current; and a second heating coil which is supplied with the high-frequency current. The first heating coil has an approximate V-shaped part. The second heating coil has an approximately M-shaped part. The first heating coil and the second heating coil are approximately configured in parallel so that the approximate V-shaped part of the first heating coil and the approximate M-shaped part of the second heating coil are connected and crossed through a non-electrical mode for forming an approximate quadrilateral space. At least one selected from the first heating coil and the second heating coil is movable in an approximate parallel direction.
Description
technical field [0001] The present invention relates to an induction heating device, and in more detail, relates to a thin-plate-shaped object to be heated (hereinafter, "thin-plate-shaped object to be heated" is referred to as " An induction heating device used when heating a thin plate-shaped object to be heated"). Background technique [0002] In general, when induction heating a thin-plate-shaped object to be heated of a magnetic material, heating is performed using an induction heating device having a so-called tunnel coil as a heating coil. [0003] However, when inductively heating a thin-plate-shaped object to be heated of a non-magnetic material, if the induction heating device having such a tunnel coil is used for heating, the induced currents generated on the surface and back of the thin-plate-shaped object to be heated will cancel each other out. , cannot be heated. [0004] Therefore, when inductively heating a non-magnetic thin-plate-shaped object to be heate...
