Abstract

A heating appliance includes a housing defining a food product compartment having at least a front door and a rear wall opposite the front door. The heating appliance also includes a rack configured to support a food product within the food product compartment. The heating appliance also includes a heating assembly disposed within the food product compartment and an elongate heating device having a first length, and an angled heat distribution member having a second length disposed between the heating device and the rack. The heat distribution member includes a pattern of apertures and the heat distribution member is configured to prevent infrared radiation produced by the heating device from directly reaching the rear wall of the housing, except for infrared radiation that passes through the apertures of the heat distribution member.

First claim

What is claimed is:

1. A heating appliance, comprising:
a housing defining a food product compartment having at least a front door and a rear wall opposite the front door;
a rack configured to support a food product within the food product compartment; and
a heating assembly disposed within the food product compartment, the heating assembly including:
an elongate heating device having a first length, and
an angled heat distribution member having a second length, the heat distribution member comprising a first substantially planar portion disposed and extending between the heating device and the rack and connected with a second substantially planar portion at an angle with the second portion extending between the heating device and the rear wall, wherein the heat distribution member comprises a pattern of apertures, and wherein the heat distribution member is configured to prevent infrared radiation produced by the heating device from directly reaching the rear wall of the housing, except for infrared radiation that passes through the apertures of the heat distribution member.

2. The heating appliance of claim 1 , wherein the heat distribution member includes a substantially planar vertical section as the first portion and a substantially planar horizontal section as the second portion.

3. The heating appliance of claim 2 , wherein the vertical section extends vertically beyond the heating device, and wherein the vertical section is located relatively closer to the rear wall of the housing when compared to the distance between the heating device and the rear wall of the housing.

4. The heating appliance of claim 2 , wherein the vertical section and the horizontal section form a substantially right angle.

5. The heating appliance of claim 1 , wherein the second length is equal to or greater than the first length.

6. The heating appliance of claim 1 , wherein the pattern is configured to reflect more infrared radiation produced by the heating device nearer a midpoint of the second length, wherein the second length is divided into three portions, including a first portion, a second middle portion, and a third portion, and wherein the pattern of apertures reflect more infrared radiation produced by the heating device in the second middle portion than either of the first and third portions.

7. An elongate heat distribution member for selectively diffusing and shielding a thermal transmission of infrared radiation produced by an elongate heating device in an oven, the heat distribution member comprising:
a first elongate substantially planar portion;
a second elongate substantially planar portion connected to the first substantially planar portion, the second substantially planar portion forming an angle relative to the first substantially planar portion; and
a plurality of apertures disposed on the first and second substantially planar portions such that the heating device creates an evenly-distributed thermal transmission to a food product within the oven;
wherein at least one of the first and second substantially planar portions are configured to prevent direct thermal transmission from the heating device to a rear wall of the oven when the heat distribution member is mounted within the oven proximate the heating device, except for thermal transmission that passes through the apertures of the heat distribution member.

8. The elongate heat distribution member of claim 7 , wherein the angle formed by the first and second substantially planar portions is substantially a right angle.

9. The elongate heat distribution member of claim 7 , wherein the first substantially planar portion is horizontal, and wherein the second substantially planar portion is vertical.

10. The elongate heat distribution member of claim 7 , wherein the plurality of apertures are also disposed on the angled portion.

11. The elongate heat distribution member of claim 7 , wherein the elongate heating device has a length divided into three portions, including a first portion, a second middle portion, and a third portion, and wherein the plurality of apertures reflect more infrared radiation produced by the elongate heating device in the second middle portion than either of the first and third portions.
