Abstract

The present invention provides a device for cooking food that has a cooking cavity defined by a front wall, a back wall that opposes the front wall, two opposing side walls, a ceiling, and a floor that opposes the ceiling; a substrate for supporting a food item, the substrate substantially enclosed by the cavity; a first plenum spanning between the two opposing side walls, said plenum comprising a first segment proximal to the back wall, a second segment proximal to the ceiling, and at least one third segment that joins the first segment and the second segment; a second plenum positioned proximal to but medially displaced from the first plenum; a flame heating element located between the first plenum and the second plenum; and at least one air movement device located proximal to a region in which the front wall and ceiling intersect.

Claims

1. A device for cooking food, said device comprising:

a cooking cavity, wherein the cavity is defined by a front wall, a back wall that opposes the front wall, two opposing side walls, a ceiling, and a floor that opposes the ceiling;

a substrate for supporting a food item, the substrate substantially enclosed by the cavity;

an air deflector panel spanning between the two opposing side walls, said air deflector panel comprising a first segment proximal to the back wall, a second segment proximal to the ceiling, and at least one angled segment that joins the first segment and the second segment;

a webbing defining a plurality of apertures positioned proximal to but medially displaced from the air deflector panel, wherein the webbing spans between the two side walls and extends from the floor, and wherein the webbing comprises a first region that is parallel to the first segment of the air deflector panel, a second region that is parallel to at least a portion of the angled segment of the air deflector panel, and;

an open flame heating element located between the air deflector panel and the webbing; and

at least one air movement device located proximal to a region in which the front wall and ceiling intersect.

2. The device of claim 1, wherein a secondary air inlet is located on the back wall and transports air to the space between the air deflector panel and webbing and under the open flame heating element.

3. The device of claim 2, wherein the back wall has a longitudinal axis defining its length, and wherein the secondary air inlet is a channel extending along the length of the back wall.

4. The device of claim 1, wherein a flame sensor is placed between the air deflector panel and the webbing and proximal to the flame heating element.

5. The device of claim 1, wherein the substrate for supporting a food item is a plurality of baskets.

6. The device of claim 1 wherein the air deflector panel further comprises a medially facing surface, and wherein said medially facing surface is polished to a high reflective gloss.

7. The device of claim 6 wherein light from the open flame heating element is reflected from the medially facing surface of the air deflector panel and backlights the plurality of apertures defining the webbing.

8. The device of claim 1 wherein the open flame heating element heats the webbing and the webbing radiates heat into the cooking cavity.

9. The device of claim 1 wherein the at least one air movement device is angled to direct air towards a medial portion of the cavity and onto the substrate for supporting a food item.
