US 4,321,857 A · Infrared gas grill

Abstract

A sheet metal cabinet supports a gas burner assembly below the forward portion of a shield, over which are a pair of removable primary cooking gridirons, having spaced, parallel, transversely extending U-shaped grids which cover the upper opening of the grill cabinet, the U-shaped grids having holes in their end portions so that the grease may drip onto a drip pan or grease tray which extends rearwardly of the burner assembly. A secondary gridiron or bake rack, is supported by a tubular upright rectangular hood assembly above the drip pan and over the rear portion of the primary gridirons. The hood has a front L-shaped access door hinged at the top of the hood by a transverse hinge. The burner assembly has tandem arranged burners with upwardly open, plenum boxes, the top portions of which are covered by a plurality of ceramic, juxtaposed, rectangular, foraminous, radiant burner elements. LP gas, from a tank carried within the cabinet, is fed through control valves which respectively control gas fed to the plenum chambers of the plenum boxes. Auxiliary equipment includes a rotisserie which is removably carried by the hood, a smoke box within which moist wood chips are placed, the box being placed on the burner assembly for heating. One of the primary gridiron is selectively replaced by a deep fat frier which is suspended by the cabinet over one of the burners. The gridirons are also replaceable by a frying griddle.

Dependent claims

A grill assembly comprising:

(a) a cabinet;
(b) a source of combustible gas;
(c) a gas burner assembly in said cabinet, said gas burner having a plenum box with a plenum chamber communicating with said source of combustible gas for receiving gas therefrom, said plenum box being supported by and disposed in the interior of said cabinet, said plenum box having an open upper portion open to said plenum chamber, a foraminous radiant burner element over said open upper portion, said radiant burner element being provided with plurality of gas passageways through which the combustible gas which enters said plenum chamber passes to the exterior upper surface of said burner element for burning at the upper surface of said burner element to generate heat and products of combustion;
(d) a fire shield carried by said cabinet, said fire shield defining a channel above said element and through which the products of combustion pass from said element;
(e) a stationary food supporting means disposed above said element for supporting items of food in spaced relationship to said burner element for being cooked by the heat generated by the combustion of said combustible gas at said of said burner.
