Abstract

An oven appliance includes a cooking chamber defined at least in part by a bottom wall having an outlet port defined therein, wherein the outlet port defines a virtual boundary projected in the vertical direction, a burner positioned below the bottom wall proximate the outlet port and outside of the virtual boundary of the outlet port, and a burner shield. The burner shield includes a cover portion positioned directly over the burner, and a first extension having a first edge connected to the cover portion and a second edge opposite the first edge, wherein the first extension extends toward the outlet port.

First claim

What is claimed is:

1. A burner assembly of an oven appliance comprising a bottom wall and an outlet port defined in the bottom wall, the burner assembly comprising:
a burner positioned below the bottom wall proximate the outlet port and outside of a virtual boundary of the outlet port that extends in a vertical direction, wherein the burner comprises a plurality of first gas ports facing a rear of the oven appliance in the transverse direction and a plurality of second gas ports facing a front of the oven appliance in the transverse direction, and wherein a length between the plurality of first gas ports and a front edge of the virtual boundary of the outlet port in the transverse direction is shorter than a length between the plurality of second gas ports and a vertical center line of the bottom wall in the transverse direction; and
a burner shield comprising:
a cover portion positioned directly over the burner; and
a first extension having a first edge connected to the cover portion and a second edge opposite the first edge, wherein the first extension extends toward the outlet port.

2. The burner assembly of claim 1 , wherein the cover portion is curved such that a convex side of the cover portion faces the bottom wall and the burner is provided under a concave side of the cover portion.

3. The burner assembly of claim 2 , wherein the burner shield further comprises a second extension having a first edge connected to the cover portion and a second edge connected to the bottom wall, and wherein the second extension extends from the bottom wall at a first predetermined angle with respect to the vertical direction.

4. The burner assembly of claim 3 , wherein the second edge of the first extension is located higher than an apex of the convex side of the cover portion.

5. The burner assembly of claim 3 , wherein the burner extends in the lateral direction, and wherein a junction between the first extension and the cover portion is in a horizontal plane below a top of the burner and above a top of the plurality of gas ports.

6. The burner assembly of claim 5 , wherein the first extension extends from the cover portion at a second predetermined angle with respect to the vertical direction.

7. The burner assembly of claim 6 , wherein the plurality of first gas ports is greater than the plurality of second gas ports.

8. The burner assembly of claim 1 , wherein the burner is spaced apart from a front edge of the virtual boundary of the outlet port by a distance in the transverse direction that is shorter than a width of the outlet port in the transverse direction.

9. The burner assembly of claim 1 , wherein the first extension extends at least partially into the virtual boundary of the outlet port.

10. An oven appliance defining a vertical direction, lateral direction, and transverse direction, the oven appliance comprising:
a cooking chamber defined at least in part by a bottom wall having an outlet port defined therein, wherein the outlet port defines a virtual boundary projected in the vertical direction;
a burner positioned below the bottom wall proximate the outlet port and outside of the virtual boundary of the outlet port, wherein the burner is spaced apart from a front edge of the virtual boundary of the outlet port by a distance in the transverse direction that is shorter than a width of the outlet port in the transverse direction; and
a burner shield comprising:
a cover portion positioned directly over the burner; and
a first extension having a first edge connected to the cover portion and a second edge opposite the first edge, wherein the first extension extends toward the outlet port.

11. The oven appliance of claim 10 , wherein the cover portion is curved such that a convex side of the cover portion faces the bottom wall and the burner is provided under a concave side of the cover portion.

12. The oven appliance of claim 11 , wherein the burner shield further comprises a second extension having a first edge connected to the cover portion and a second edge connected to the bottom wall, and wherein the second extension extends from the bottom wall at a first predetermined angle with respect to the vertical direction.

13. The oven appliance of claim 12 , wherein the second edge of the first extension is located higher than an apex of the convex side of the cover portion.

14. The oven appliance of claim 12 , wherein the burner extends in the lateral direction and comprises a plurality of first gas ports facing a rear of the oven appliance in the transverse direction, and wherein a junction between the first extension and the cover portion is in a horizontal plane below a top of the burner and above a top of the plurality of gas ports.

15. The oven appliance of claim 14 , wherein the burner further comprises a plurality of second gas ports facing a front of the oven appliance in the transverse direction, and wherein the first extension extends from the cover portion at a second predetermined angle with respect to the vertical direction.

16. The oven appliance of claim 15 , wherein a length between the plurality of first gas ports and a front edge of the virtual boundary of the outlet port in the transverse direction is shorter than a length between the plurality of second gas ports and a vertical center line of the bottom wall in the transverse direction.

17. The oven appliance of claim 10 , wherein the first extension extends at least partially into the virtual boundary of the outlet port.
