Provided are an electromagnetic induction type heating device, a hot-blast generating device and a power generating device, which are useful as a highly efficient, safe and economical heat source with a simple constitution in an ordinary household and an agricultural field. Permanent magnets (1a) are arranged equidistantly in a rotor (1). In a structure according to this invention, there are provided the rotor (1) rotated by a motor (3), a heat generating portion (2) arranged near the rotor (1) and having a conductor arranged in the magnetic field by the permanent magnets (1a), and a hot-blast trapping plate (6) arranged near the heat generating portion (2) and having a plurality of hot-blast communicating holes (6a). The rotor (1) is rotated at a high speed by a spindle (3c) connected to the motor (3). Moreover, a thermocouple (4) is connected with the heat generating portion (2), thereby to convert the heat energy, which might otherwise dissipate into the ambient air, again into an electric energy. Furthermore, the electromagnetic induction type heating device is constituted by arranging the hot-blast trapping plate (6) having the hot-blast communicating holes (6a), near the heat generating portion (2). |
