Abstract

A cap for a gas burner is disclosed. The cap includes a center portion including a top surface having a periphery; at least one extension extending outward from the center portion, the at least one extension defining a drain channel extending outward and downward from the top surface; and a ledge extending along the periphery. A spill resistant gas burner assembly incorporating such a cap is also disclosed.

Claims

1. A cap for a gas burner, the cap comprising:

a center portion comprising a top surface having a periphery;

at least one extension extending outward from the center portion, the at least one extension defining a drain channel extending outward and downward from the top surface; and

a ledge extending along the periphery.

2. The cap of claim 1, wherein the at least one extension comprises a plurality of extensions distributed along the periphery, the ledge extending between adjacent ones of the extensions.

3. The cap of claim 1, wherein the drain channel extends outward and downward from the top surface at a predetermined angle.

4. The cap of claim 3, wherein the predetermined angle is at least 10 degrees.

5. The cap of claim 2, wherein the top surface is substantially circular, the extensions being substantially uniformly distributed along the periphery.

6. A spill resistant gas burner assembly comprising:

a first gas burner having a top; and

a cap positioned on the first gas burner, the cap comprising;

a center portion comprising a top surface having a periphery, the top surface being spaced apart from the top of the first gas burner;

a plurality of extensions distributed along the periphery and extending outward therefrom, the extensions defining respective drain channels each extending outward and downward from the top surface; and

a ledge extending along the periphery and between adjacent ones of the drain channels.

7. The assembly of claim 6, wherein the first gas burner has a lateral wall or a periphery and a plurality of first main gas discharge ports on the lateral wall or the periphery, the lateral wall or the periphery having first portions vertically aligned with the ledge and second portions vertically aligned with the extensions, the first main gas discharge ports being distributed only in the first portions.

8. The assembly of claim 7, wherein the first main gas discharge ports are substantially uniformly distributed along the first portions.

9. The assembly of claim 7, wherein the first gas burner further comprises an igniter for igniting gas flowing out of the first main gas discharge ports.

10. The assembly of claim 7, wherein the lateral wall or the periphery has a plurality of carry-over ports which are distributed only in the second portions for carrying over flames from first main gas discharge ports on one side of each extension to first main gas discharge ports on the other side of said each extension.

11. The assembly of claim 10, wherein the carry-over ports are substantially uniformly distributed along the second portions.

12. The assembly of claim 6, wherein each drain channel extends outward and downward from the top surface at a predetermined angle.

13. The assembly of claim 12, wherein the predetermined angle is at least 10 degrees.

14. The assembly of claim 6, wherein the top surface is substantially circular, the extensions being substantially uniformly distributed along the periphery.

15. The assembly of claim 6, further comprising a second gas burner surrounding the first gas burner and having a plurality of second main gas discharge ports, the assembly further comprising a cover disposed on the second gas burner for covering the second main gas discharge ports.

16. The assembly of claim 15, wherein the cover has a substantially annular shape having an inner periphery, an outer periphery, and a top surface extending inward and downward from the outer periphery toward the inner periphery, the inner periphery being disposed between the first gas burner and the second gas burner, each extension extending beyond the inner periphery.

17. The assembly of claim 16, wherein said each extension comprises an upper end which terminates at the center portion and a lower end which is spaced apart from the top surface of the cover.

18. The assembly of claim 17, wherein the lower end is disposed between the inner periphery and the outer periphery.

19. The assembly of claim 7, wherein each extension comprises an upper end which terminates at the center portion and a lower end which is radially spaced apart from the lateral wall or the periphery of the first gas burner by at least 5/16 inches.
