In this case, heating is performed by the heat of reflection by the reflecting plate and the hot air by the blower fan, which shows superior heating and heating efficiency compared with the conventional electric heating apparatus, but is made of an alloy of iron, chromium, and nickel as a heating element. Since the filament is used, the heating element is directly in contact with the air, and oxidation is promoted, which not only has a problem in durability, but also exposes the heating element, which causes a fire and does not exert an excellent heating effect. In addition, when the heating element is damaged, the replacement is difficult.

The present invention has been invented to solve the conventional problems as described above, and its object is to use a halogen heating lamp that is easy to exchange, generates heat and has excellent durability as a medium for generating heat, and in a halogen heating lamp. By reflecting the generated heat to the front by the reflector and directing the hot air to the front by the blower, it greatly improves the durability of the heat-generating medium and also greatly improves the heating efficiency and heating effect. It is to provide a heat generating device.
