Abstract

A compact non-rotational mounting feature or mechanism is employed for mounting an orifice holder to a support member below a cooktop of a gas cooking appliance. More specifically, the holder and support member include interengaging polygonal structure, such as a key-shaped anti-rotational peg and hole combination, allowing the holder to be initially mated with the support member in a manner which prevents relative rotation and assuring that the holder is appropriately positioned for proper alignment of various gas burner components, such as an orifice, a gas line, electrode, flame spreader and other burner related structure. Upon exacting the positioning of the holder relative to the support member, the holder to fixed in position by a mechanical fastener.

First claim

I claim:

1. In a gas cooking appliance including a cooktop with a gas burner, a burner box mounted below the cooktop and an orifice holder for holding and positioning an orifice underneath the gas burner of the gas cooking appliance, the orifice holder comprising:
a mounting assembly for mounting the orifice holder to the burner box below the cooktop, said mounting assembly including a polygonal member configured to be positioned in a polygonal-shaped receiver formed in the base of the burner box to fixedly locate the orifice holder relative to the burner box in only a single, predetermined orientation.

2. The orifice holder according to claim 1 , wherein the mounting assembly further includes a non-polygonal member, with the polygonal member extending from the non-polygonal member and both the polygonal member and the non-polygonal member being adapted to project into the polygonal-shaped receiver.

3. The orifice holder according to claim 2 , wherein the polygonal member and the non-polygonal member define, in combination, a key-shaped anti-rotational peg.

4. The orifice holder according to claim 2 , wherein the non-polygonal member is circular.

5. The orifice holder according to claim 4 , wherein the polygonal member is rectangular.

6. A gas cooking appliance comprising:
a cooktop;
a burner box mounted below the cooktop;
at least one gas burner;
an orifice holder for holding and positioning an orifice underneath the at least one gas burner, the orifice holder being interposed between the burner box and the at least one gas burner; and
a mounting assembly for mounting the orifice holder to the burner box, said mounting assembly including a polygonal member which is positioned in a polygonal-shaped receiver to assure fixedly locating the orifice holder relative to the burner box in only a single, predetermined orientation.

7. The gas cooking appliance according to claim 6 , wherein said polygonal member projects from the orifice holder and the polygonal-shaped receiver is provided in a bracket mounted to the burner box, in a plateau member projecting upward from a base of the burner box or in a base of the burner box.

8. The gas cooking appliance according to claim 7 , wherein the polygonal-shaped receiver constitutes an opening into which the polygonal member projects.

9. The gas cooking appliance according to claim 8 , wherein the mounting assembly further includes a non-polygonal member, with the polygonal member extending from the non-polygonal member and both the polygonal member and the non-polygonal member projecting into the opening.

10. The gas cooking appliance according to claim 9 , wherein the polygonal member and the non-polygonal member define, in combination, a key-shaped anti-rotational peg.

11. The gas cooking appliance according to claim 9 , wherein the non-polygonal member is circular.

12. The gas cooking appliance according to claim 11 , wherein the polygonal member is rectangular.

13. The gas cooking appliance according to claim 11 , further comprising: a plate interposed between the burner box and the orifice holder, said plate including the polygonal-shaped receiver and being separately fixed to each of the orifice holder and the burner box.

14. The gas cooking appliance according to claim 6 , wherein the orifice holder further includes a mounting boss configured to threadably receive a mechanical fastener for further securing the orifice holder.

15. A method of mounting an orifice holder to a burner box mounted below a cooktop in a gas cooking appliance, wherein said orifice holder is for holding and positioning an orifice underneath a gas burner of the gas cooking appliance, the method comprising:
positioning a polygonal member of the orifice holder in a polygonal-shaped receiver to assure fixedly locating the orifice holder relative to the burner box in only a single, predetermined orientation.

16. The method of claim 15 , wherein positioning a polygonal member of the orifice holder in a polygonal-shaped receiver constitutes mounting the orifice holder to one of a bracket mounted to the burner box, a plateau member projecting upward from a base of the burner box or a base of the burner box.

17. The method of claim 15 , wherein positioning a polygonal member of the orifice holder in a polygonal-shaped receiver includes inserting a polygonal-shaped peg projecting from the orifice holder into a polygonal-shaped opening.

18. The method of claim 17 , wherein inserting the polygonal-shaped peg projecting from the orifice holder into the polygonal-shaped opening constitutes inserting a key-shaped anti-rotational peg into a key-shaped opening.

19. The method of claim 15 , further comprising:
fixing a plate, including the polygonal-shaped receiver, to the orifice holder; and
further fixing the plate to the burner box such that the plate is interposed between the burner box and the orifice holder.

20. The method of claim 15 , wherein the orifice holder further includes a non-polygonal member, with the non-polygonal member being circular and extending directly from the polygonal member, and wherein positioning a polygonal member of the orifice holder in a polygonal-shaped receiver is performed by simultaneously inserting the polygonal and non-polygonal members into the polygonal-shaped receiver.
