Abstract
An infrared heater includes a combustion chamber having a radiator with a surface arranged to direct radiant heat in a forward heating direction. A fan has an outlet opening which is located to direct a flow of air above the radiating surface, thereby deflecting convective air heated by the combustion chamber in the forward direction. The fan is mounted above and on the rear side of the chamber so that it is out of the influence of radiant and convective heat developed by the chamber. A motor which drives the fan is mounted at one end of the fan so that the motor is also not affected by the radiant and convective heat.
Claims9
A heating apparatus comprising a combustion chamber including a generally cylindrical housing, a radiator forming a part of the exterior of said housing and having a radiating surface which extends over the axial length of said chamber for directing radiant heat in a forward heating direction transverse to the axis of said chamber so that an object located away from said chamber in the forward heating direction is directly heated by radiation, casing means on the exterior of said housing for reducing heat radiation from said radiator in directions other than the forward heating direction, fan means including an elongated case which forms an outlet opening substantially coextensive with said radiating surface in the axial direction of said chamber for deflecting convective air which rises above the exterior of said chamber in said forward direction, said case being mounted to said casing means above said chamber on the rear side of said chamber facing opposite said heating direction so that said fan means is out of the influence of radiant and convective heat developed by said chamber, said outlet opening facing in the same direction as said forward heating direction, and a motor mounted at one end of said fan means for driving said fan means so that said motor is out of the influence of said radiant and convective heat.
