ABSTRACT:
Cooking apparatus adapted for multi-purpose use as a grill, oven, stove or patio heater, and comprising a chamber formed by a lower housing section having upright walls and by a hinged cover for opening and closing the top of the chamber. The bottom of the chamber is open to admit a low velocity, large volume flow of fresh air into the chamber. A single gas burner extends lengthwise of the chamber adjacent the open bottom and can be regulated for cooking to produce a low, yellow-tipped blue flame which creates a narrow zone of incandescence in a much wider layer of incombustible bodies supported on a grate spaced above the burner. The cooking zone is spaced above the grate and contains one or more grills extending generally coextensive with the layer of incombustible material so that at least the major portion of the cooking area is horizontally offset out of vertical alignment with the zone of incandescence. The enclosure has a perimeter outlet smaller than the air inlet and located between the upper edges of the lower section walls and the overhanging side walls of the cover. The large volume air flow vertically upwardly through the vertically spaced zones is induced solely by convection currents generated by the burner and incombustible bodies, the latter serving as means for dispersing the heat, baffling the upward air flow and emitting radiant heat. Additional features include an exterior drip tray adapted to control admission of air to the chamber, an anti-flare grease diverter, a burner and grate subassembly which is readily removable and usable by itself as a fireplace heater, a cook-top cover and associated auxiliary cover.
