Abstract

An infrared heater and ventilator unit comprises a rectangular, sheet metal housing adapted to be mounted in the ceiling of a room with the lower end of the housing approximately flush with the ceiling. Two infrared lamps are mounted in sockets that are fastened to the underside of a narrow bar or strap that extends centrally across the housing. A small fan is mounted on the strap between the lamps to blow heat therefrom downwardly into the room; and a ventilator blower is mounted above the fan to draw air upwardly into the housing from the room, and to exhaust the air into the space above the ceiling. The fan motor is wired to operate whenever one or more of the lamps is energized; and the blower is operable independently of the lamps.

Claims

1. A combination heater-ventilator unit, comprising an open-ended housing adapted to be secured in an opening in the ceiling of a room with an open end facing downwardly, a metal strap extending transversely across said housing above said open end and bowed downwardly intermediate its ends, an electric fan mounted on the underside of said strap centrally thereof and above said open end to blow air downwardly through the open end of said housing, a pair of spaced lamp sockets each removably holding an infrared lamp mounted on the underside of said strap at opposite sides, respectively, of said fan to diverge from one another, a centrifugal blower mounted in said housing above said strap and having its inlet facing said fan substantially centrally of said housing, and having an exhaust port communicating with an opening in one side of said housinG, means for energizing said blower independently of said lamps and fan, means for selectively energizing either one or both of said lamps, means operative to energize said fan whenever at least one of said lamps is energized, and a grille mounted below said housing over its open end, said grille being bowed downwardly between its sides and having openings therein registering with said lamp sockets and the lamps mounted therein, through which air heated by said lamps is blown out into the room, said grille being spaced outwardly beyond said housing around the perimeter of said housing and being spaced downwardly from the ceiling to provide an opening between the housing and the grille through which air is drawn from the room into said housing when said blower is operating.

2. A combination heater-ventilator unit as defined in claim 1, wherein said blower-energizing means comprises a first switch connected to said blower and movable into and out of closed position selectively to energize and deenergize said blower, and said lamp-energizing means comprises a second switch movable independently of said first switch, and selectively between a first position in which it deenergizes said lamps and said fan, a second position in which it energizes said fan and one of said lamps, and a third position in which it energizes said fan and both of said lamps.
