Abstract
A cooktop appliance and a gas burner assembly are provided. The gas burner assembly includes an annular burner body positioned at a top surface of a top panel of the cooktop appliance. The burner body forms a central combustion zone, a plurality of flame ports at the central combustion zone, and a mixing chamber upstream from the plurality of flame ports. A fuel manifold forms an outlet passage spaced apart from an inlet at the burner body such that gaseous fuel is flowable from the outlet passage at the fuel manifold into the mixing chamber through the inlet at the burner body, and such that air is entrained into the mixing chamber by the flow of gaseous fuel entering the mixing chamber through the inlet at the burner body.
Claims18
A cooktop appliance, comprising:
- a top panel;
- and
- a gas burner assembly positioned at the top panel, the gas burner assembly comprising an annular burner body positioned at a top surface of the top panel, the annular burner body forming a central combustion zone, a plurality of flame ports at the central combustion zone, and a mixing chamber upstream from the plurality of flame ports to permit a fuel-air mixture to flow into the central combustion zone through the plurality of flame ports, the annular burner body being open at the central combustion zone such that a circumferentially bounded portion of the top panel is vertically exposed through the annular burner body at the central combustion zone;
- and
- a fuel manifold positioned beneath the top panel and upstream from the mixing chamber at the burner body, the fuel manifold forming an outlet passage spaced apart from an inlet at the burner body such that gaseous fuel is flowable from the outlet passage at the fuel manifold into the mixing chamber through the inlet at the burner body, and such that air is entrained into the mixing chamber by the flow of gaseous fuel entering the mixing chamber through the inlet at the burner body;
- and
- a thermal break formed along the circumferentially bounded portion of the top panel below the plurality of flame ports, wherein the thermal break comprises a conductive heat sink extending from the fuel manifold to a top face disposed beneath a bottom surface of the top panel at the circumferentially bounded portion of the top panel such that the conductive heat sink is in conductive thermal communication with the bottom surface of the top panel.
A gas burner assembly for a cooktop appliance, the burner assembly comprising:
- an annular burner body disposable at a top surface of a top panel of the cooktop appliance, the annular burner body forming a central combustion zone, a plurality of flame ports at the central combustion zone, and a mixing chamber upstream from the plurality of flame ports to permit a fuel-air mixture to flow into the central combustion zone through the plurality of flame ports, the annular burner body being open at the central combustion zone such that a circumferentially bounded portion of the top panel is vertically exposed through the annular burner body at the central combustion zone;
- and
- a fuel manifold disposable beneath the top panel and upstream from the mixing chamber at the burner body, the fuel manifold forming an outlet passage spaced apart from an inlet at the burner body such that gaseous fuel is flowable from the outlet passage at the fuel manifold into the mixing chamber through the inlet at the burner body, and such that air is entrained into the mixing chamber by the flow of gaseous fuel entering the mixing chamber through the inlet at the burner body;
- and
- a thermal break formed along the circumferentially bounded portion of the top panel below the plurality of flame ports, wherein the thermal break comprises a conductive heat sink extending from the fuel manifold to a top face disposed beneath a bottom surface of the top panel at the circumferentially bounded portion of the top panel such that the conductive heat sink is in conductive thermal communication with the bottom surface of the top panel.
