Abstract

An orifice holder includes a body that defines an inner chamber and inner wall portions. The inner wall portions each have a first width that is defined relative to the upper portion of the body. A first cup extends outwardly from the inner wall portions. A second cup extends outwardly from the inner wall portions and interconnects with the first cup through the inner wall portions. An airflow path is defined to the inner chamber from the first and second cups.

First claim

What is claimed is:

1. A gas burner assembly for a cooktop, comprising:
a spreader defining a top and an underside and including a stem extending from the underside to a depth and having a first diameter, wherein the stem defines an opening to the top of the spreader; and
an orifice holder having a body defining central inner wall portions receiving a portion of the stem, the body further defining at least one inner chamber and at least one cup outwardly extending from the inner wall portions around the at least one inner chamber and in fluid communication with the opening in the stem between the inner wall portions to define an airflow path directed into the at least one inner chamber of the body from an open upper portion of the body, and wherein the at least one cup facilitates direction of the airflow path.

2. The gas burner assembly of claim 1 , wherein:
the at least one cup is a cavity defined by an extruded profile; and
the extruded profile includes a linear portion and a curved portion extending from an end and a side of each of the inner wall portions, respectively.

3. The gas burner assembly of claim 1 , wherein the stem is tapered from a second diameter adjacent to the underside to an end of the stem defining the depth, the first diameter of the stem being defined on the end having a narrow width relative to the second diameter.

4. The gas burner assembly of claim 1 , wherein the at least one cup includes a first cup and a second cup, and wherein the open upper portion of the orifice holder is in fluid communication with each of the first and second cups.

5. The gas burner assembly of claim 4 , wherein the first and second cups each include a first lobe and a second lobe, wherein the first and second lobes are in fluid communication between the open upper portion of the orifice holder and the opening of the stem.

6. The gas burner assembly of claim 5 , wherein each of the first and second cups includes a peripheral rim defining an indentation, the indentation of each of the first and second cups separating the first lobe and the second lobe.

7. The gas burner assembly of claim 1 , wherein the at least one cup includes a single cup surrounding the inner wall portions.

8. A cooktop, comprising:
a surface;
a spreader defining a top and an underside, wherein a singular stem extends away from the underside and defines an opening therethrough; and
an orifice holder including a body defining inner wall portions configured to receive the singular stem, a first cup, and a second cup, the first and second cups each extending outwardly from the inner wall portions and each defining an inner chamber, wherein an airflow path to the stem through the first and second cups extends from between the surface and underside of the spreader and is directed through the inner chamber of each of the first and second cups.

9. The cooktop of claim 8 , wherein:
the first and second cups each include a first lobe and a second lobe; and
the airflow path is further defined through an open upper portion of the orifice holder and through each of the first and second lobes.

10. The cooktop of claim 9 , wherein each of the first and second cups include a peripheral rim defining an indentation that separates each of the first and second lobes.

11. The cooktop of claim 8 , wherein sidewalls of the body include holes that further define the airflow path.

12. The cooktop of claim 8 , wherein the body further defines a first pillar and a second pillar proximate the inner wall portions and within a gap defined therebetween.

13. The cooktop of claim 8 , wherein the inner wall portions are tapered and configured to maintain a distance between the underside of the spreader and the surface.

14. The cooktop of claim 8 , wherein each of the first and second cups define holes configured to draw the airflow path into the body of the orifice holder.

15. An orifice holder, comprising:
a body defining an inner chamber and inner wall portions, each having a first width defined relative to an upper portion of the body;
a first cup extending outwardly from the inner wall portions; and
a second cup extending outwardly from the inner wall portions and interconnected with the first cup through the inner wall portions, wherein an airflow path is defined to the inner chamber from the first and second cups toward a closed bottom of the body and is directed toward the inner wall portions and into the inner chamber by the first and second cups.

16. The orifice holder of claim 15 , wherein a peripheral rim at an upper portion of the orifice holder defines an indentation of each of the first and second cups, and wherein the indentation separates a first lobe and a second lobe of each of the first and second cups.

17. The orifice holder of claim 16 , wherein the first and second lobes further define the airflow path within the first and second cups.

18. The orifice holder of claim 15 , wherein each of the first and second cups each define an oblong shape configured to direct the airflow path within the body.

19. The orifice holder of claim 15 , wherein a second width of the inner wall portions is defined relative to a lower portion of the body and is narrower than the first width of the inner wall portions located relative to an upper portion of the body.

20. The orifice holder of claim 15 , wherein the first and second cups are each cavities defined by respective extruded profiles that include a linear portion and a curved portion, the linear portion extending outward from an end of each of the inner wall portions, and the curved portion extending outward from a side of each of the inner wall portions.
