Abstract

An orifice holder includes a body defining inner wall portions facing each other and spaced apart at a first distance for receiving a portion of a stem of a spreader therebetween. The body further defines a first cup and a second cup, each extending outwardly from opposing sides of the inner wall portions. Each of the first cup and the second cup has a peripheral rim extending around an upper perimeter thereof and open at respective adjacent ends of the inner wall portions to define a fluid path past the peripheral rims, through the respective first and second cups, between the inner wall portions, and into the stem.

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 inner wall portions facing each other and spaced apart at a first distance for receiving a portion of the stem therebetween, the body further defining a first cup and a second cup, each extending outwardly from opposing sides of the inner wall portions, each of the first cup and the second cup having a peripheral rim extending around an upper perimeter thereof and open at respective adjacent ends of the inner wall portions to define a fluid path past the peripheral rims, through the respective first and second cups, between the inner wall portions, and into the stem.

2. The gas burner assembly of claim 1 , wherein:
the first cup and the second cup each include 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 , the spreader is supported by the stem being received between the inner wall portions of the body such that the underside of the spreader is spaced apart from the peripheral rim of each of the first cup and the second cup.

5. The gas burner assembly of claim 4 , wherein a portion of a fluid flow path past the peripheral rim is through a space defined between the peripheral rim and the underside of the spreader.

6. The gas burner assembly of claim 1 , wherein the first and second cups each include a first lobe and a second lobe, wherein a fluid flow path passes between an open upper portion of the orifice holder and the opening of the stem.

7. The gas burner assembly of claim 6 , wherein the peripheral rim of each of the first and second cups defines an indentation, the indentation of each of the first and second cups separating the first lobe and the second lobe.

8. A cooktop, comprising:
a surface defining at least one aperture;
a spreader defining a top and an underside, wherein a stem extends away from the underside and defines an opening therethrough; and
an orifice holder having a body defining inner wall portions facing each other and spaced apart at a first distance for receiving a portion of the stem therebetween, the body further defining a first cup and a second cup, each extending outwardly from opposing sides of the inner wall portions, each of the first cup and the second cup having a peripheral rim extending around an upper perimeter thereof, extending into the aperture of the surface, and open at respective adjacent ends of the inner wall portions to define a fluid path through the aperture, through the respective first and second cups, between the inner wall portions, and into the stem.

9. The cooktop of claim 8 , wherein a portion of an airflow path is defined between the surface and the underside of the spreader.

10. The cooktop of claim 9 , wherein the spreader is supported by the stem being received between the inner wall portions of the body such that the underside of the spreader is spaced apart from the peripheral rim of each of the first cup and the second cup and maintained above the surface.

11. The cooktop of claim 8 , wherein:
the first and second cups each include a first lobe and a second lobe; and
wherein an airflow path is further defined through each of the first and second lobes.

12. The cooktop of claim 9 , wherein the peripheral rim of each of the first and second cups defines an indentation, the indentation of each of the first and second cups separating the first lobe and the second lobe.

13. 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.

14. 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.

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

16. 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, each of the first cup and the second cup having a peripheral rim extending around an upper perimeter thereof and open at respective adjacent ends of the inner wall portions, wherein an airflow path is defined past the peripheral rims to the inner chamber from the first and second cups.

17. The orifice holder of claim 16 , wherein the peripheral rims each define 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.

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

19. The orifice holder of claim 16 , wherein each of the first and second cups each define an oblong shape configured to direct the airflow path within the body.

20. The orifice holder of claim 16 , 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.
