ABSTRACT:
A portable, electrical space heater adapted to be placed and turned on in any enclosure where a suitable source of electrical energy is available. The heater is characterized by an open framework in which an electric fan is contained, and a surmounting, partially enclosed electrical heating unit. Air drawn in by the fan is delivered upward to an enclosed side of the heating unit. The heating unit comprises a series of spaced, generally horizontal plates of progressively increasing breadth from the bottom plate to the top one, each plate having spaced, downwardly inclined front and rear margins. Electrical heating units interposed between adjacent plates are suitably connected to a common source of electrical energy. The air delivered upward by the fan is distributed laterally to the plates, is intercepted and delivered forward past the heater units by the rear progressively projecting downturned margins of the plates, and is diverted downward by the front, desirably aligned, downturned margins of the plates, being thereby delivered toward the floor which will generally be the coldest part of the room or enclosure. The fan is thermostatically cut off as the temperature falls and turned on as the temperature rises. The generation of heat is automatically interrupted as long as the room temperature remains at a comfortably warm set level.
