Abstract

A grilling appliance includes first and second fuel delivery ports extending from a grill housing, a first burner element selectively connected to one of the first and second fuel delivery ports to define a single-burner condition, a second burner element selectively connected to the other of the first and second fuel delivery ports to define, with the first burner element, a twin-burner condition, an elongated burner element having two fuel inlets selectively connected to the first and second fuel delivery ports to define, when the first and second burner elements are removed from the first and second fuel delivery ports and a large-burner condition. At least one ignitor is in communication with the first burner element in the single-burner condition, the first and second burner elements in the twin-burner condition and the elongated burner element in the large-burner condition.

First claim

What is claimed is:

1. A grilling appliance comprising:
first and second fuel delivery ports extending from a grill housing;
a first burner element selectively connected to one of the first and second fuel delivery ports to define a single-burner condition;
a second burner element selectively connected to the other of the first and second fuel delivery ports to define, with the first burner element, a twin-burner condition;
an elongated burner element having two fuel inlets selectively connected to the first and second fuel delivery ports to define, when the first and second burner elements are removed from the first and second fuel delivery ports, a large-burner condition; and
at least one ignitor in communication with the first burner element in the single-burner condition, the first and second burner elements in the twin-burner condition and the elongated burner element in the large-burner condition, wherein the at least one ignitor is in a fixed position within the grill housing in the single-burner, twin-burner and large-burner conditions.

2. The grilling appliance of claim 1 , wherein the each of the first and second fuel delivery ports define a closed state when free of connection with one of the first burner element, the second burner element and the elongated burner element, wherein the closed state is defined by at least one of the first and second fuel delivery ports being free of delivery of fuel.

3. The grilling appliance of claim 1 , wherein the at least one ignitor includes a first ignitor proximate the first fuel delivery port and a second ignitor proximate the second fuel delivery port.

4. The grilling appliance of claim 3 , wherein one of the first and second ignitors is deactivated in the large-burner condition.

5. The grilling appliance of claim 1 , wherein the first and second fuel delivery ports are in communication with a fuel source, wherein fuel from the fuel source is selectively delivered to one of the first and second fuel delivery ports in the single-burner condition, and wherein fuel from the fuel source is selectively delivered to at least one of the first and second fuel delivery ports in the twin-burner and large-burner conditions.

6. The grilling appliance of claim 1 , wherein the first and second fuel delivery ports are simultaneously controlled by a single user interface when in the large-burner condition.

7. The grilling appliance of claim 1 , wherein the first and second fuel delivery ports are in communication with a natural gaseous fuel line.

8. A grilling appliance comprising:
first and second fuel delivery ports in selective communication with at least one ignitor;
first and second small burner elements selectively engagable with at least one of the first and second fuel delivery ports to define a single-burner condition and a twin-burner condition, wherein the single-burner condition is defined by one of the first and second small burner elements being in communication with one of the first and second fuel delivery ports and the other of the first and second small burner elements being out of communication with the other of the first and second fuel delivery ports, and wherein the twin-burner condition is defined by the first small burner element being in communication with one of the first and second fuel delivery ports and the second small burner element being in communication with the other of the first and second fuel delivery ports; and
an elongated burner element alternatively engagable with the first and second fuel delivery ports to define a large-burner condition, wherein the first and second fuel delivery ports are simultaneously controlled by a single user interface when in the large-burner condition.

9. The grilling appliance of claim 8 , wherein the first small burner element has a first width and the second small burner element has a second width, wherein the first width is greater than the second width.

10. The grilling appliance of claim 8 , wherein the elongated burner element includes first and second fuel inlets and a plurality of burner apertures extending around a perimeter edge of the elongated burner element, and wherein the elongated burner element includes an internal fuel delivery structure that places each burner aperture of the plurality of burner apertures in communication with each of the first and second fuel inlets.

11. The grilling appliance of claim 8 , wherein the at least one ignitor is in a fixed position within a grill housing in the single-burner, twin-burner and large-burner conditions.

12. The grilling appliance of claim 8 , wherein the at least one ignitor includes a first ignitor proximate the first fuel delivery port and a second ignitor proximate the second fuel delivery port.

13. The grilling appliance of claim 8 , wherein the each of the first and second fuel delivery ports define a closed state when free of connection with one of the first small burner element, the second small burner element and the elongated burner element, wherein the closed state is defined by at least one of the first and second fuel delivery ports being free of delivery of fuel.

14. The grilling appliance of claim 12 , wherein one of the first and second ignitors is deactivated in the large-burner condition.

15. The grilling appliance of claim 8 , wherein the first and second fuel delivery ports are in communication with a fuel source, wherein fuel from the fuel source is selectively delivered to one of the first and second fuel delivery ports in the single-burner condition, and wherein fuel from the fuel source is selectively delivered to at least one of the first and second fuel delivery ports in the twin-burner and large-burner conditions.

16. A grilling appliance comprising:
a set of burner elements;
a plurality of fuel delivery ports, wherein the set of burner elements are selectively and interchangeably engaged with at least one of the fuel delivery ports to define a plurality of burner conditions, wherein each fuel delivery port of the plurality of fuel delivery ports defines a closed state when disengaged from the set of burner elements;
at least one ignitor in communication with the plurality of fuel delivery ports in each of the burner conditions, wherein the at least one ignitor is in a fixed position with respect to the plurality of fuel delivery ports.

17. The grilling appliance of claim 16 , wherein the set of burner elements includes first and second small burner elements and an elongated burner element, and wherein the plurality of burner conditions includes a single-burner condition defined by one of the first and second small burner elements being in communication with one of a first fuel delivery port and a second fuel delivery port of the plurality of fuel delivery ports, a twin-burner condition defined by the first and second small burner elements being in communication with the first and second fuel delivery ports, respectively, and a large-burner condition defined by the elongated burner element being in communication with the first and second fuel delivery ports.

18. The grilling appliance of claim 17 , wherein the at least one ignitor includes a first ignitor proximate the first fuel delivery port and a second ignitor proximate the second fuel delivery port, and wherein one of the first and second ignitors is deactivated in the large-burner condition.
