Abstract: The present invention provides a modular fan construction in which the fan motor, with its operating controls, can be tested away from the fan housing and then fit into the housing without disassembly after the testing.

Abstract: An electric fan heater includes a stationary housing and a louver blade assembly having a plurality of oscillating louver blades located forwardly in the housing for providing multidirectional hot air flow from the heater. The heater also includes a drive system for the louver blade assembly with the drive system comprising lightweight plastic drive gears and a small rubber drive belt located rearwardly in the housing as well as a lightweight plastic connecting shaft extending forwardly from the drive gears to the louver blade assembly. The electric heating element for providing hot air from the heater is positioned between the louver blade assembly and the plastic drive gears. The gears and connecting shaft are located in the housing laterally outwardly from the heating element to avoid direct exposure to the heat therefrom.

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.

Abstract: The present invention provides a fan structure having a housing and vane arrangement adapted to oscillate relative to the housing. The fan motor is used to operate both the fan blade and the vane arrangement. The structure includes a drive system having a rotating drive shaft for driving an oscillator which is adapted to oscillate the vanes and a control mechanism for controlling on/off switching of the drive system to the oscillator. Accordingly, the fan blade is operated independently of the oscillator so that the structure can be run both with and without oscillation of the vanes.
