Abstract
The invention relates to an electromagnetic heating device with a magnetic stripe shielding protection structure. The electromagnetic heating device comprises a heating unit, an electromagnetic coil and an outer cover. A 20-mm insulating thermal-insulating layer is arranged between the heating unit and the electromagnetic coil. The magnetic stripe shielding protection structure is formed by wrapping a group of magnetic stripes on the outer layer of the electromagnetic coil. The magnetic stripes are arranged annularly to form a magnetic stripe band. The distance between every two adjacent magnetic stripes is larger than 30 mm and smaller than 50 mm. The fixing mode of the magnetic stripe band is that a fabric band is arranged on the outer layer of the electromagnetic coil in a sleeving mode to form shielding. The electromagnetic heating device has the advantages that in order to solve the problem that iron metal can not exist within 40 mm of an external magnetic field of a heating coil, the magnetic stripe shielding protection structure is additionally arranged on the outer layer of the electromagnetic coil and used for shielding the external magnetic field and changing the direction of magnetic force lines, so that the magnetic force lines do not diffuse outwards; even if iron metal materials exist on the outer portion of the heating coil, the iron metal materials can not be heated, and only a heated unit can be heated, so the magnetic flux of the heated unit is increased, and the heated unit can be heated more quickly; thus, electric energy consumption is lowered, and the heat supply efficiency is improved.
