Claims19
A cooking appliance comprising:
- a housing having a cooktop surface defining at least one air channel therethrough, wherein said at least one air channel includes one or more exit openings through said cooktop surface;
- at least one gas burner positioned in said cooktop surface;
- at least one cooking grate having a cooking surface and a venting surface and combined as a unitary structure, wherein both said cooking surface and said venting surface of said at least one cooking grate is disposed over said cooktop surface of said housing, said venting surface permitting air to exit from said one or more exit openings of said cooktop surface through said at least one air channel of said housing, wherein said cooking surface is adjacent said at least one gas burner and said venting surface has one or more openings therethrough to fluidly communicate with said at least one air channel;
- and
- wherein said venting surface includes an outer peripheral skirt spaced upwardly from said cooktop surface and surrounding a plurality of vanes defining said one or more openings therethrough, wherein said outer peripheral skirt is continuous and surrounds said one or more exit openings of said at least one air channel to define a downstream passageway in fluid communication from said one or more exit openings of said at least one air channel to said one or more openings through said venting surface and wherein said at least one air channel exhausts airflow from inside said housing though said one or more openings of said venting surface.

A cooking appliance comprising:
- a housing having a cooktop surface defining at least one air channel therethough, wherein said at least one air channel includes at least one exit opening through said cooktop surface at the rear of said housing;
- at least one gas burner extending from said cooktop surface;
- a cooking grate having a cooking surface and a venting surface and combined as a unitary structure, wherein said venting surface includes an upper surface, said venting surface having one or more vanes defining one or more openings of said venting surface, wherein said cooking surface includes an upper surface with one or more openings;
- said cooking surface is disposed over said at least one gas burner and said venting surface is disposed over said exit opening of said cooktop surface defining said at least one air channel, wherein said at least one air channel exhausts airflow from inside said housing through said one or more openings of said venting surface;
- wherein said venting surface includes an outer periphery frame, wherein said outer periphery frame is continuous and surrounds said at least one exit opening of said cooktop surface defining said at least one air channel to define a downstream passageway in fluid communication from said at least one exit opening of said cooktop surface defining said at least one air channel to said one or more openings through said venting surface;
- and
- a free end of said outer periphery frame surrounding said at least one exit opening of said cooktop surface is spaced from said cooktop surface by one or more feet of said cooking grate.

A cooking appliance comprising:
- a housing having one or more gas burners and one or more air channels, wherein said one or more gas burners and one or more exit openings of said one or more air channels extends through a cooktop surface, wherein said one or more exit openings of said one or more air channels is positioned behind said one or more gas burners adjacent a back of said housing cooktop surface;
- at least one cooking grate having an upper surface extending across a cooking surface and a venting surface combined as a unitary structure, wherein an outer periphery of said venting surface rearwardly extends from an outer periphery of said cooking surface, wherein said venting surface includes a depending skirt adjacent and continuous about said outer periphery of said venting surface and a plurality of vanes to define a cavity in fluid communication with said one or more exit openings of said housing and said upper surface of said at least one cooking grate outside said cooking surface;
- wherein said depending skirt of said venting surface is spaced from and above said cooktop surface defining said one or more exit openings;
- and
- wherein said at least one cooking grate allows heat to flow upward from said one or more gas burners and allows airflow to vent exhaust from said one or more exit openings of said one or more air channels from inside said housing through said plurality of vanes of said venting surface.
