ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a radiant electric space heater and, although not so limited, this invention is particularly directed to a portable horizontal radiant electric space heater for household use.
INCORPORATION BY REFERENCE
The disclosures of U.S. Pat. Nos. 5,381,509 and 5,437,001 are hereby incorporated by reference herein. A copy of each of these patents is enclosed. These patents show, respectively, a horizontal electric space heater and an upright electric space heater.
BACKGROUND OF THE INVENTION
Space heaters of the type shown in the aforementioned patents are highly satisfactory for their intended use for providing radiant heat to the surrounding space. However, their use is limited to supplying heat, and in some cases to serve as an humidifier, and it is advantageous to provide an electric space heater capable of performing another function.
SUMMARY OF THE INVENTION
An object of this invention is to provide an improved electric space heater capable of acting also as an air freshener. In accordance with this invention, a space heater is provided with a potpourri dish in a position to be heated and thereby efficiently freshen the surrounding air space.
Other objects and advantages will become apparent from the following description and the drawings.
