Abstract

A heating appliance includes a cooktop having a plurality of burners. A burner box defines a burner position for each burner, each burner position having a plurality of slots. An orifice holder is slidably engaged with the plurality of slots in a linear direction. Opposing flanges extend from a bottom portion of the orifice holder that extend through the plurality of slots to be at least partially secured therein, wherein the opposing flanges are adapted to engage the plurality of slots in only one directional orientation.

First claim

What is claimed is:

1. A heating appliance comprising:
a cooktop having a plurality of burners;
a burner box defining a burner position for each burner, each burner position having a plurality of slots;
an orifice holder slidably engaged with the plurality of slots in a linear direction; and
opposing flanges extending from a bottom portion of the orifice holder that extend through the plurality of slots to be at least partially secured therein, wherein the opposing flanges are adapted to engage the plurality of slots in only one directional orientation.

2. The heating appliance of claim 1 , wherein at least one of the plurality of slots includes an aperture having a locating feature, and wherein one flange of the opposing flanges includes a locating surface that corresponds to the locating feature.

3. The heating appliance of claim 1 , wherein engagement of the opposing flanges with the plurality of slots defines a loose connection of the orifice holder within the burner position, and wherein the loose connection between the orifice holder and the burner box is supplemented by at least one fastener that extends through the cooktop and into an upper portion of the orifice holder.

4. The heating appliance of claim 1 , wherein each slot includes at least one deflecting tab, wherein each deflecting tab is biased downward from a retaining state to an entry state when the opposing flanges are moved through the plurality of slots and toward a securing position.

5. The heating appliance of claim 4 , wherein the deflecting tabs return to the retaining state when the opposing flanges are in the securing position, wherein the deflecting tabs serve to retain the opposing flanges in the securing position and prevent movement of the opposing flanges out of the securing position.

6. The heating appliance of claim 1 , wherein the plurality of slots include two opposing slots that are separated by a linear guide, and wherein the opposing flanges are separated by a corresponding linear channel, wherein engagement of the linear channel within the linear guide limits perpendicular movement of the opposing flanges through the opposing slots.

7. The heating appliance of claim 4 , wherein the securing position of the opposing flanges is defined by the linear channel of the orifice holder engaging the burner box from above and the opposing flanges of the orifice holder engaging the burner box from below.

8. The heating appliance of claim 2 , wherein each opposing flange includes an angled leading surface that slidably engages the aperture of each respective slot, wherein engagement of the angled leading surface with the aperture promotes linear sliding movement of the opposing flanges into a securing position.

9. A heating appliance comprising:
a cooktop having a plurality of burners;
a burner box defining a burner position for each burner, each burner position having a plurality of slots;
an orifice holder slidably engaged with the plurality of slots in a linear direction; and
opposing flanges extending from a bottom portion of the orifice holder that extend through narrowed portions of the plurality of slots to be at least partially secured therein, wherein the opposing flanges are adapted to engage the plurality of slots in only one directional orientation.

10. The heating appliance of claim 9 , wherein at least one of the plurality of slots includes a locating feature, and wherein at least one flange of the opposing flanges includes a locating surface that corresponds to the locating feature.

11. The heating appliance of claim 9 , wherein engagement of the opposing flanges with the plurality of slots defines a loose connection of the orifice holder within the burner position, and wherein the loose connection between the orifice holder and the burner box is supplemented by at least one fastener.

12. The heating appliance of claim 9 , further comprising:
a deflecting tab that is biased downward from a retaining state to an entry state when the opposing flanges are moved through the plurality of slots and toward a securing position.

13. The heating appliance of claim 12 , wherein the deflecting tab is located near the plurality of slots.

14. The heating appliance of claim 12 , wherein the deflecting tabs serve to retain the opposing flanges in the securing position and prevent movement of the opposing flanges out of the securing position.

15. The heating appliance of claim 9 , wherein the plurality of slots include two opposing slots that are separated by a linear guide that selectively engages the opposing flanges.

16. The heating appliance of claim 12 , wherein the securing position of the opposing flanges is defined by a linear channel of the orifice holder engaging the burner box from above and the opposing flanges of the orifice holder engaging the burner box from below.

17. The heating appliance of claim 10 , wherein each opposing flange includes an angled leading surface that slidably engages an aperture of each respective slot, wherein engagement of the angled leading surface with the aperture promotes linear sliding movement of the opposing flanges into a securing position.

18. A heating appliance comprising:
a burner box defining a burner position for a burner, the burner position having a plurality of slots;
an orifice holder slidably engaged with the plurality of slots in a linear direction; and
opposing flanges extending from a bottom portion of the orifice holder that extend through the plurality of slots to be at least partially secured therein, wherein the opposing flanges are adapted to engage the plurality of slots in only one directional orientation.

19. The heating appliance of claim 18 , wherein each slot includes at least one deflecting tab, wherein each deflecting tab is biased downward from a retaining state to an entry state when the opposing flanges are moved through the plurality of slots and toward a securing position.

20. The heating appliance of claim 18 , wherein the plurality of slots include two opposing slots that are separated by a linear guide, and wherein the opposing flanges are separated by a corresponding linear channel, wherein engagement of the linear channel within the linear guide limits perpendicular movement of the opposing flanges through the opposing slots.
