A combination heater-light-ventilator unit for mounting in a ceiling, is disclosed. A cylindrical housing supports the unit and an annular grille on its bottom includes an arcuate heat discharge outlet around part of its circumference and an arcuate air intake through the remainder, with a light diffuser supported in the center. The heat discharge outlet is configured to direct heat flow relatively straight down from the unit to minimize its recirculation through the arcuate air intake.

This invention relates to an improved heat-light-ventilator unit, and more particularly to a unit of the type which is adapted to be mounted in the ceiling or wall of a bathroom, kitchen or the like for heating, lighting or ventilating of the same.
Combination heater-light-ventilator units are known to the prior art. U.S. Pat. No. 3,320,406 issued May 16, 1967 to Wainwright is one item of such prior art. The most relevant art known to me, which is an improvement on Wainwright, is a heater-light-ventilator unit manufactureed and sold by Fasco industries Inc. as model #657 C. The present invention is an improvement on this prior art.
In Fasco model 657 C, a ceiling-mounted unit has a rectangular face with lights mounted in rectangular portions of the unit at each end, and a heater-ventilator occupying the central portion. A heating element is in the foreground (toward the room) and a fan is mounted behind it, the fan communicating with a duct or exhaust port through which to move air for ventilation of the room. Operation of the heater, lights, and ventilator fan are independent. They can be operated alone, in any combination, or all together.
FIG. 1 is a top view of a heater-light-ventilator unit according to this invention.
FIG. 2 is a side elevation view of the same, with the housing broken away and somewhat schematically represented as being mounted between ceiling joints.
FIG. 3 is a bottom view of the unit, generally as it is seen from below once it is mounted as in FIG. 2.
Referring now to the drawing, numeral 10 designates generally the combination heater-light-ventilator unit of this invention. The unit 10 is mounted in a cylindrical housing 12 which in turn is adapted for connection by suitable mounting bars 14 between ceiling joists 16. The ceiling surface is represented at 18 in FIG. 2. The combined heater-light-ventilator system of this invention is mounted within (or supported by) the housing 12.
An electric heater 20 is disposed in a heater housing 22 adjacent the inlet to a heater fan or blower 24. Heat-blower 24 moves air through a heater-blower housing 26 to a discharge outlet 28 which occupies an arcute portion A of the lower grille 30, mounted to the bottom of the housing 12. Lower grille 30, through the major part of its circumference, is ported as represented at 32 so that there is free communication from below the grille 30 to within the housing 12.
A lamp 34 is mounted within a domed reflector 36 to direct light downward through a diffuser 38. Diffuser 38 is removably mounted to the grille 30 for changing of the lamp and cleaning of the diffuser, as required.
