Abstract

A cooking apparatus includes a cooking cavity and a heat source located within the cooking cavity. A shield is mounted relative to the heat source wherein the shield includes at least one side edge with an undulating pattern. The undulating pattern is configured to deflect heat from the heat source to different sections of the cooking cavity to provide a substantially uniform distribution of heat within the cooking cavity.

Claims (29)

1. A cooking apparatus comprising:

a cooking cavity;

a heat source located within the cooking cavity and configured to increase a temperature of the cooking cavity, wherein the heat source is a broiler element mounted to a top wall of the cooking cavity, and wherein the heat source extends along a longitudinal axis;

a shield mounted directly below the heat source, the shield having a top surface and a bottom surface, the top surface facing a top wall of the cooking cavity and the bottom surface facing into an interior of the cooking cavity,

wherein the shield further includes a first side edge and a second side edge opposite the first side edge, at least one of the first and second side edges defining a sinusoidal pattern extending along a horizontal plane oriented along the longitudinal axis; and

wherein the sinusoidal pattern is configured to deflect heat from the heat source to different sections of the cooking cavity; and

wherein the shield further includes opposing first and second end edges positioned between the first and second side edges, the first and second end edges having lengths of less than half a length of the first and second side edges.

2. The cooking apparatus of claim 1 , wherein the at least one of the first and second side edges includes a convex portion, wherein the convex portion is configured to deflect heat to an outer section of the cooking cavity located laterally to the side of the longitudinal axis.

3. The cooking apparatus of claim 1 , wherein the at least one of the first and second side edges includes a concave portion, wherein the concave portion deflects heat to a central section of the cooking cavity located vertically below the longitudinal axis.

4. The cooking apparatus of claim 1 , wherein the sinusoidal pattern includes at least two convex portions and one concave portion positioned between the two convex portions.

5. The cooking apparatus of claim 1 , wherein the at least one of the first and second side edges includes a plurality of curves.

6. The cooking apparatus of claim 1 , wherein the shield includes at least two opposing side edges having a sinusoidal pattern defining the side edges.

7. A cooking apparatus comprising:

a cooking cavity;

a heat source located within the cooking cavity and configured to increase a temperature of the cooking cavity, wherein the heat source is a broiler element mounted to a top wall of the cooking cavity;

a shield mounted directly below the heat source, wherein the shield includes a longitudinal axis, the shield having a top surface and a bottom surface, the top surface facing a top wall of the cooking cavity and the bottom surface facing into an interior of the cooking cavity;

wherein the shield further includes a first side edge and a second side edge opposite the first side edge, the first and second side edges located along a horizontal plane, wherein the first and second side edges each include a convex portion and a concave portion that are located, respectively, at varying distances from a vertical plane passing through the longitudinal axis of the shield such that the first and second sides edges are configured to deflect heat to different sections of the cooking cavity,

wherein the concave portion deflects heat emitted from the heat source to a central section of the cooking cavity that is vertically below the longitudinal axis, and the convex portion deflects heat emitted from the heat source to an outer section of a cooking cavity located laterally to the side of the central section.

8. The cooking apparatus of claim 7 , wherein the shield includes a recess formed therein for receiving a corresponding portion of the heat source.

9. The cooking apparatus of claim 8 , wherein the recess is a longitudinal channel of substantially the same curvature as the heat source.

10. The cooking apparatus of claim 7 , wherein the shield includes first and second end edges, the first and second end edges having lengths of less than half the lengths of the first and second side edges.

11. A cooking apparatus comprising:

a cooking cavity;

a heat source located within the cooking cavity and configured to increase a temperature of the cooking cavity, wherein the heat source is a broiler element mounted to a top wall of the cooking cavity, and wherein the heat source extends along a longitudinal axis;

a shield mounted directly below the heat source and extending along the longitudinal axis, wherein the shield includes a top surface facing a top wall of the cooking cavity, a bottom surface facing into an interior of the cooking cavity, at least a first side edge and a second side edge opposite the first side edge,

wherein the first side edge and the second side edge each include convex portions alternating with a concave portion, wherein the concave and convex portions of the shield define a sinusoidal pattern along a horizontal plane oriented along the longitudinal axis,

wherein the concave portion deflects heat emitted from the heat source to a central section of the cooking cavity and the convex portions deflect heat emitted from the heat source to an outer section of a cooking cavity located laterally to the side of the central section.

12. The cooking apparatus of claim 11 , wherein the shield is configured such that heat emitted from the heat source is distributed substantially evenly throughout the cooking cavity.

13. The cooking apparatus of claim 11 , wherein the first side edge and second side edge further includes two convex portions.
