Multi-ringed burner with spill containment

1. A gas burner assembly for a cooking appliance including a cooktop surface, said gas burner assembly comprising:

an outer gas burner comprising an outer burner body, said outer gas burner configured to provide an outer cooking flame; and

an inner gas burner comprising an inner burner body, said inner gas burner configured to provide an inner cooking flame, wherein air supplied to said inner gas burner flows through one or more openings in a base burner assembly through said cooktop surface other than a gas inlet for said inner gas burner, wherein one or more channels comprise a spill path beneath said outer gas burner onto said cooktop surface,

wherein said base burner assembly and said outer burner body define an annular gap providing a flow path for said air from said one or more openings into said annular gap, and

wherein said base burner assembly comprises a spill reservoir spaced apart from said inner burner body and shaped such that a first portion of said air flowing into said spill reservoir from said annular gap flows into said gas inlet and a second portion of said air flowing into said spill reservoir from said annular gap provides secondary air for said inner burner body.

2. The gas burner assembly of claim 1 , wherein said one or more openings are substantially hidden from view by said outer gas burner.

3. The gas burner assembly of claim 1 , wherein spills are channeled out of said gas burner assembly onto a top of said cooktop surface.

4. The gas burner assembly of claim 1 , wherein a portion of said air flows through space between the base burner assembly and said outer burner body.

5. The gas burner assembly of claim 1 , wherein a periphery of said gas burner assembly further comprises at least one opening aligned with said one or more channels and wherein said gas burner assembly is substantially sealed with said cooktop surface.

6. The gas burner assembly of claim 1 , wherein said outer burner body and said inner burner body are substantially concentric.

7. A gas cooking appliance comprising:

a cooktop surface; and

a gas burner assembly comprising:

an outer gas burner comprising an outer burner body, said outer gas burner configured to provide an outer cooking flame; and

an inner gas burner comprising an inner burner body, said inner gas burner configured to provide an inner cooking flame, wherein air supplied to said inner gas burner flows through one or more openings in a base burner assembly through said cooktop surface other than a gas inlet for said inner gas burner, wherein one or more channels comprise a spill path beneath said outer gas burner onto said cooktop surface,

wherein said base burner assembly and said outer burner hod define an annular gap providing a flow path for said air from said one or more openings into said annular gap, and

wherein said base burner assembly comprises a spill reservoir spaced apart from said inner burner body and shaped such that a first portion of said air flowing into said spill reservoir from said annular gap flows into said gas inlet and a second portion of said air flowing into said spill reservoir from said annular gap provides secondary air for said inner burner body.

8. The gas cooking, appliance of claim 7 , wherein said one or more openings are substantially hidden from view by said outer gas burner.

9. The gas cooking appliance of claim 7 , wherein spills are channeled out of said gas burner assembly onto a top of said cooktop surface.

10. The gas cooking appliance of claim 7 , wherein a periphery of said gas burner assembly further comprises at least one opening aligned with said one or more channels and wherein said gas burner assembly is substantially sealed with said cooktop surface.

11. The gas cooking appliance of claim 7 , wherein said outer burner body and said inner burner body are substantially concentric.
