Abstract

A domestic gas cooking appliance for heating a food item is provided. The domestic cooking appliance includes a top sheet; a burner body on the top sheet, the burner body having an upwardly extending riser pin; a gas supply line that supplies gas to the burner body; and a burner cap positioned above the burner body and resting on the riser pin such that a pin receiving area contacts the riser pin. One of the riser pin and the pin receiving area comprises a magnet, and the other of the riser pin and the pin receiving area comprises a ferrous material.

First claim

What is claimed is:

1. A gas burner for a domestic gas cooking appliance; the gas burner comprising:
a burner body having an upwardly extending riser pin; and
a burner cap positioned above the burner body and resting on the riser pin such that a post receiving area contacts the riser pin,
wherein one of the riser pin and the post receiving area comprises a magnet, and the other of the riser pin and the post receiving area comprises a ferrous material.

2. The gas burner of claim 1 , wherein the burner cap further comprises a locating feature that interacts with the riser pin to positively locate the burner cap relative to the burner body in a direction perpendicular to an axial direction of the riser pin.

3. The gas burner of claim 2 , wherein the burner body comprises a plurality of the riser pin, and
the burner cap further comprises a locating feature that interacts with the plurality of riser pins to positively locate the burner cap relative to the burner body in a direction perpendicular to an axial direction of the riser pins.

4. The gas burner of claim 1 , wherein the riser pin comprises the ferrous material.

5. The gas burner of claim 4 , wherein the riser pin comprises a pin body and a pin cap,
the pin cap is attached to the pin body and forms an upper region of the pin body,
the pin body and the burner body are a same material, and
the pin cap is the ferrous material.

6. The gas burner of claim 1 , wherein the burner body comprises a plurality of the riser pin, and
the burner cap is supported by only the plurality of riser pins.

7. The gas burner of claim 1 , wherein the pin receiving area comprises the ferrous material.

8. The gas burner of claim 7 , wherein the burner body comprises a plurality of the riser pin, and
the burner cap further comprises a locating feature that interacts with the plurality of riser pins to positively locate the burner cap relative to the burner body in a direction perpendicular to an axial direction of the riser pins.

9. A domestic gas cooking appliance for heating a food item, comprising:
a top sheet;
a burner body on the top sheet, the burner body having an upwardly extending riser pin;
a gas supply line that supplies gas to the burner body; and
a burner cap positioned above the burner body and resting on the riser pin such that a pin receiving area contacts the riser pin,
wherein one of the riser pin and the pin receiving area comprises a magnet, and the other of the riser pin and the pin receiving area comprises a ferrous material.

10. The domestic gas cooking appliance of claim 9 , wherein the riser pin comprises the ferrous material.

11. The domestic gas cooking appliance of claim 10 , wherein the burner body and the riser pin are different materials.

12. The domestic gas cooking appliance of claim 11 , wherein the burner body and the burner cap are dissimilar metals.

13. The domestic gas cooking appliance of claim 10 , wherein the riser pin comprises a pin body and a pin cap,
the pin cap is attached to the pin body and forms an upper region of the pin body,
the pin body and the burner body are a same material, and
the pin cap is the ferrous material.

14. The domestic gas cooking appliance of claim 13 , wherein the domestic gas cooking appliance comprises a plurality of the riser pin, and
the burner cap is supported by only the plurality of riser pins.

15. The domestic gas cooking appliance of claim 9 , wherein the domestic gas cooking appliance comprises a plurality of the riser pin, and
the burner cap is supported by only the plurality of riser pins.

16. The domestic gas cooking appliance of claim 9 , wherein the magnet is a magnet that can function as a magnet at 450 degrees Fahrenheit.

17. The domestic gas cooking appliance of claim 9 , wherein the pin receiving area comprises the ferrous material.

18. The domestic gas cooking appliance of claim 17 , wherein the riser pin comprises a pin body and a pin cap,
the pin cap is attached to the pin body and forms an upper region of the pin body,
the pin body and the burner body are a same material, and
the pin cap comprises the magnet.

19. The domestic gas cooking appliance of claim 9 , wherein the burner cap further comprises a locating feature that interacts with the riser pin to positively locate the burner cap relative to the burner body in a direction perpendicular to an axial direction of the riser pin.

20. The domestic gas cooking appliance of claim 9 , wherein the domestic gas cooking appliance comprises a plurality of the riser pin, and
the burner cap further comprises a locating feature that interacts with the plurality of riser pins to positively locate the burner cap relative to the burner body in a direction perpendicular to an axial direction of the riser pins.
