Description of the invention: [Technical field to which the invention belongs] The tree is related to the type of induction plus, more specifically, to the heat of the non-magnetic material and the magnetic material (4). In the following, an induction heating device in which "the thin-plate-shaped object to be heated" is appropriately referred to as a "thin-plate-shaped object to be heated" is heated. [Prior Art] ❹ n is inductively heated in a thin plate-shaped object to be heated. The N-type heating coil is heated by using an induction heating device having a so-called channel type coil. However, when the thin plate-shaped object to be heated of the non-magnetic material is inductively heated, the induction current generated by the surface of the thin plate-shaped object and the back surface is heated by the induction heating device having such a channel-type coil.

In the case of a large amount, the induced current concentrates on the edge portion of the thin plate-shaped object to be heated, causing a problem that the edge portion is excessively heated (see Fig. 1). As a method for solving this problem, for example, there is a patent document of the Japanese Patent Laid-Open Publication No. SHO-63-317630, Patent Document No. JP-A-2007-122924, or a copy of Patent Document 3.

The object to be heated is heated, wherein the magnetic flux is generated by using a primary coil (ie, a heating coil wound around the ferrite core) between the thin plate-shaped object to be heated and the ferrite core. > The secondary coil that generates the secondary magnetic flux without leakage flux is lowered by the temperature rise at both ends of the metal plate and the temperature of the inner portion of the both ends is 099107751 201041453 degrees. Further, in the induction heating technology disclosed in Japanese Laid-Open Patent Publication No. Hei 8-37084, the two substantially J-shaped conductors disposed on the respective magnetic flux guides are arranged in a facing arrangement to form a central space. The heating coil group 'heats the thin plate-shaped object to be heated by passing through a space formed by the heating coil group, wherein the portion is formed by combining two substantially J-shaped conductors Month (tab) is not overheated at the end of the sheet by the 0 heater. However, in the techniques disclosed in Patent Document 1 and Patent Document 2, the induction heating portion of the induction heating device is substantially entirely composed of a magnetic material, and in the technique disclosed in Patent Document 3, it is constituted by a magnetic flux guide member of a predetermined length. Since the heating coil group is disposed in the opposite direction, the overall weight of the apparatus becomes very large, and a high cost problem arises during installation and transportation.

portion of the thin plate-shaped object 24 to be heated on the %-I side or the lower side is also excessively heated. However, in the induction heating device 1A, the heating coil 18 and the heating coil 20' are combined to form not only a substantially square-shaped space si' but also a substantially square shape in which the heating coil 18 and the heating coil 20 are not electrically connected. Spaces S2 and S3 having substantially triangular shapes are formed in a region where the thin plate-shaped object 24 is not conveyed on the lower side of the space S1. In the substantially triangular shaped spaces S2, S3, the magnetic flux is generated from the inner surface of the plane in Fig. 3 due to the flow of the high-frequency current, which is opposite to the magnetic flux generated in the space si. magnetic flux. Therefore, in the vicinity of the edge portions 24a and 24b of the thin plate-shaped object 24 to be conveyed on the lower side of the transport space S1, a magnetic flux which is opposite to the magnetic flux passing through the thin plate-shaped object 24 is generated, and a part of the magnetic flux in the opposite direction passes through the edge. The portions 24a and 24b' are induced to flow in the opposite direction to the eddy current induced by the thin plate-shaped object 24 by the eddy currents 099107751 12 201041453 in the edge portions 24a and 24b of the thin plate-shaped object 24, so that the edge portions 24a and 24b can be suppressed. Excessively heated. As described above, in the induction heating device 10, the heating coil 20 having a substantially V-shaped shape is slidably disposed in the substantially heating coil 20 having a U-shape, and the heating coil can be adjusted according to the width of the thin-plate-shaped object 24 to be heated. 18 and the size of the space S1 formed by the heating coil 20, and further, the space S2, S3 which generates the magnetic flux generated in the opposite direction to the magnetic flux generated in the space si is formed adjacent to the space S1. Therefore, the magnetic flux generated by the space S1 is ❹ The edge portions 24a, 24b of the excessively heated thin plate-shaped object 24 are induced to induce eddy currents in the opposite direction, so that the edge portions 2, 24b are not excessively heated. Therefore, regardless of the magnetic material or the non-magnetic material, the induction heating device 10 can uniformly heat the plate-shaped object to be heated of various widths. Further, since the magnetic material is not used in the induction heating device 10, the weight of the entire device can be reduced as compared with the induction heating device of the prior art in which the induction heating portion is mostly made of a magnetic material. Therefore, the cost of the induction heating device during installation and transportation can be suppressed. "Others of the present invention are shown in the following (1) to (10).

The magnetic flux 'from the inner surface to the surface of the drawing in Fig. 7 is generated. In the space S4 formed by the heating coil 40 and the heating coil 41, the magnetic flux ' from the inner surface to the surface in the plane of Fig. 7 is generated' in the spaces S5, S6. A magnetic flux is generated from the surface of the drawing in Fig. 7 toward the inner surface.

In other words, as shown in Fig. 10, a plate-shaped magnetic material may be disposed on the upper side of the heating coil 18 and the heating coil 20 on the upper side of the thin plate-shaped object 24 to be heated. Therefore, the magnetic flux generated in the substantially square shape space S1 formed by the substantially V-shaped portion of the heating coil 18 and the substantially U-shaped portion of the heating coil 2 can be concentrated by the magnetic material, and the heating efficiency can be improved. Under the experiment of the inventor of the present invention, the heating efficiency of about 15% can be improved.
