Abstract
A self-cleaning gas-fueled oven for cooking with a flameholder and door which permit self-cleaning at temperatures exceeding 900.degree. F. The flameholder has a grille divided into two opposed, substantially flat portions, each of which contains an array of ports of two distinct sizes. The smaller-sized ports are tapered, increasing in cross-sectional area in the direction of gas flow through the grille. The oven door has a lip extending substantially perpendicularly from the door's sidewalls so as to overlap the periphery of the door's inner panel.
Claims24
In a gas-fueled oven, the improvement comprising an improved flameholder, for the passage of gas therethrough and subsequent ignition, for the direct heating of the interior of said oven, said flameholder comprising:
- a grille having first and second sets of ports, of different shapes, extending between and through opposite inner and outer surfaces of said grille, each of said sets of ports extending completely through said grille, each of said sets containing at least two ports, wherein each port of said second set has a minimum cross-sectional area which is greater than the minimum cross-sectional area of each port of said first set, and wherein each port of said first set increases in cross-sectional area from said inner to said outer surface.
In a gas-fueled oven, the improvement comprising an improved flameholder, for the passage of gas therethrough and subsequent ignition for the direct heating of the interior of said oven, said flameholder comprising:
- a grille having at least two sets of multiple ports, of different shapes, between opposite inner and outer surfaces, wherein each port of a first set increases in cross-sectional area from said inner to said outer surface.
In a gas-fueled oven, the improvement comprising an improved flameholder for the passage of gas therethrough and subsequent ignition, for the direct heating of the interior of said oven, the flameholder comprising:
- a grille having at least two sets of multiple ports, of different shapes and wherein the ports of each respective set are of substantially uniform configuration relative to the other ports of said respective set, between opposite inner and outer surfaces, wherein said grille includes two opposed, substantially flat portions.
