Document Type and Number:
Japanese Patent JP2741995
Kind Code:
B2
Abstract:
PURPOSE:To provide a simple infrared radiation electric heater using a conventional electric heater excellent in fastness and durability. CONSTITUTION:An electric heater 3 composed of a sheath heater is provided in a metal pipe 4 whose outer surface is coated with a black substance having high absorbing capacity and a reflecting plate 5 made of a metal such as stainless steel or an infrared radiation plate wherein a steel plate is coated with a black substance having high adsorbing capacity is provided behind the metal pipe 4. The heat value of the electric heater, the length, thickness or surface area of the metal pipe and the material applied to the outer surface of the metal pipe are selected so that the temp. of the outer surface of the metal pipe becomes about 150-350 deg.C when power is supplied to the electric heater 3. The heat generated from the electric heater is transmitted to the metal pipe having a surface area wider than that of the electric heater to efficiently convert the quantity of heat to infrared rays to emit the same from the surface of the metal pipe lower than the electric heater in temp.
