ABSTRACT:
A fan heating includes a stationary housing and a louvre blade assembly having at least one oscillating louvre blade located forwardly in the housing for providing multidirectional hot air flow from the heater. The heater further includes a drive system for the louvre blade assembly with the drive system itself including lightweight plastic drive gears located rearrwardly in the housing and a lightweight plastic connecting shaft extending forwardly from the drive gears to the louvre blade assembly. Positioned between the louvre blade assembly and the drive gears are an electric heating element for providing the hot air and a fan blade for circulating the hot air which is operated from a motor also operating the drive gears through a rubber drive belt. The drive gears and belt are located in said housing laterally outwardly away from the heating element. The fan blade is positioned to move the hot air forwardly from the heating element to the louvre blades and away from the drive gears and to move cooling air to the drive gears and connecting shaft to prevent heat related damage thereto.
