Abstract

A cooking appliance having a broiler may include a housing defining an upper compartment above the broiler and a rear compartment behind the broiler. A gas mixing pipe extends through the upper compartment to the rear compartment via an opening in an interior wall of the housing. A cover is removably coupled to an outer surface of the interior wall, such that opposing U-shaped slots of the two cover portions collectively form an aperture that conforms to an outer periphery of the gas mixing pipe. Accordingly, the cover blocks one or more gaps in the interior wall, such that the cover is configured to prevent gases from passing into the rear compartment through the gaps.

First claim

What is claimed is:

1. A cooking appliance comprising:
an oven cavity;
a housing external to the cavity, the housing defining an upper compartment above the oven cavity and a rear compartment behind the oven cavity;
a broil burner disposed within the oven cavity;
a gas mixing pipe coupled to the broil burner and extending through the upper compartment to the rear compartment via an opening in an interior wall of the housing, wherein the opening defines one or more gaps around an outer diameter of the gas mixing pipe and the gas mixing pipe is configured to deliver a fuel mixture to the broil burner; and
a cover removably coupled to an outer surface of the interior wall, the cover including a first cover portion having a first U-shaped slot and disposed adjacent the interior wall, and a second cover portion having a second U-shaped slot and disposed adjacent the first cover portion, such that the first cover portion is at least partially disposed between the second cover portion and the interior wall;
wherein the first and second U-shaped slots of the cover portions collectively define an aperture configured to receive the gas mixing pipe therethrough, such that the aperture conforms to the outer diameter of the gas mixing pipe and the cover blocks the one or more gaps, such that the cover is configured to prevent gases from passing into the rear compartment through the gaps,

wherein the first and second cover portions each comprise at least one mounting tab.

2. The cooking appliance of claim 1 , wherein the cover includes a plurality of attachment holes.

3. The cooking appliance of claim 2 , wherein the cover is configured to be coupled to the housing by a plurality of fasteners received through the plurality of attachment holes.

4. The cooking appliance of claim 3 , wherein the first cover portion and the second cover portion include attachment holes configured to align mutually, such that a single respective fastener is received through each aligned pair of the holes.

5. The cooking appliance of claim 1 , wherein the cooking appliance comprises a range.

6. The cooking appliance of claim 1 , wherein the first and second U-shaped slots are oriented in opposing directions with respect to each other when installed.

7. The cooking appliance of claim 1 , wherein the first U-shaped slot is formed in a rectangular plate of the first cover portion, the first cover portion further comprising a pair of wings extending from opposing side edges of the rectangular plate in a same direction transverse to a plane of the rectangular plate.

8. A method of preventing flame droop in a broiler, the method comprising:
coupling a first cover portion of a metal cover to a wall of an oven housing, such that a gas mixing pipe of the broiler extends through a first U-shaped slot in the first cover portion; and
coupling a second portion of the metal cover to the wall of the oven housing, such that the gas mixing pipe extends through a second U-shaped slot in the second cover portion, wherein the first and second portions of the metal cover are separate from each other when not installed;
wherein the first and second U-shaped slots collectively define an aperture conforming to an outer diameter of the gas mixing pipe, and the metal cover blocks one or more gaps in the wall, such that the metal cover is configured to prevent gases from passing into a rear compartment of the oven housing through the gaps,
wherein the first and second cover portions each comprise at least one mounting tab.

9. The method of claim 8 , wherein the cover includes a plurality of attachment holes.

10. The method of claim 9 , wherein the cover is configured to be coupled to the wall by a plurality of fasteners received through the plurality of attachment holes.

11. The method of claim 10 , wherein the first cover portion and the second cover portion include attachment holes configured to align mutually, such that a single respective fastener is received through each aligned pair of the holes.

12. The method of claim 8 , wherein the oven is mounted in a range.

13. The method of claim 8 , wherein the first and second U-shaped slots are oriented in opposing directions with respect to each other when installed.

14. The method of claim 8 , wherein the first U-shaped slot is formed in a rectangular plate of the first cover portion, the first cover portion further comprising a pair of wings extending from opposing side edges of the rectangular plate in a same direction transverse to a plane of the rectangular plate.

15. A cooking appliance comprising:
a housing defining an upper compartment above a broiler and a rear compartment behind the broiler;
a gas mixing pipe coupled to a broil burner of the broiler and extending through the upper compartment to the rear compartment via an opening in an interior wall of the housing, wherein the opening defines one or more gaps around an outer diameter of the gas mixing pipe; and
a cover removably coupled to an outer surface of the interior wall, the cover including a first cover portion having a first U-shaped slot and disposed adjacent the interior wall, and a second cover portion having a second U-shaped slot and disposed adjacent the first cover portion, such that the first cover portion is at least partially disposed between the second cover portion and the interior wall;
wherein the first and second U-shaped slots of the cover portions collectively define an aperture configured to receive the gas mixing pipe therethrough, such that the aperture conforms to the outer diameter of the gas mixing pipe and the cover blocks the one or more gaps, such that the cover is configured to prevent gases from passing into the rear compartment through the gaps,

wherein the second cover portion at least partially nests with the first cover portion.

16. The cooking appliance of claim 15 , wherein the first and second U-shaped slots are oriented in opposing directions with respect to each other when installed.

17. The cooking appliance of claim 15 , wherein the first U-shaped slot is formed in a rectangular plate of the first cover portion, the first cover portion further comprising a pair of wings extending from opposing side edges of the rectangular plate in a same direction transverse to a plane of the rectangular plate.
