Abstract: The prior art has used pitched blades attached to a stationary motor, normally electric, to move air within the confines of a structure or room. The preferred invention incorporates a series of solid discs. The discs are affixed to a stationary electric motor and thus rotate around a central axis. The discs are equally spaced and centrally perforated in a manner that will allow air to flow in high volumes through the perforations and pass along the discs thus exiting symmetrically between each disc perpendicularly to the flow of air that is at its entrance. Due to the less restrictive or low pressure air entrance as well as the correct vertical disc spacing a corresponding increase in the laminar flow is realized. This feature of the preferred invention allows for operation at a rotational speed that is practical for use as a ceiling fan.

Abstract: A space heater is mounted to a ceiling fan in close proximity to the housing of the fan motor. The housing is protected from heated air by an insulated, frusto-conical in configuration shield member. An elongate, flexible heating element is helically wound about the shield member. When the fan and heating element are operated at the same time, rotation of the fan blades causes the heated air to travel toward the ceiling at an angle determined by the frusto-conical configuration of the shield member. A cowling hides the heating elements from the view of occupants of an enclosed space within which the ceiling fan is mounted.
