Abstract: A burner base for a stacked burner assembly to secure a uniform distribution of gas flow. The burner base couples with a top burner cover and together define an internal gas mixture chamber. The burner base includes a barrier structure along a perimeter having a plurality of structural zones. A first structural zone includes a semi-circular barrier structure having a height that is taller at a middle portion than at the end portions. A second structural zone includes an arc structure having a height that is taller than the heights of adjacent structural zone heights. A third structural zone includes a semi-circular structure having a consistent height along the structure. A fourth structural zone includes a non-raised semi-circular structure. The barrier structure is configured to facilitate the distribution of the gas within the mixture chamber.

Abstract: A burner assembly includes a spreader, a burner base, and at least one annular burner cap. The spreader has a bottom and a combustion chamber that is defined by a crenellated wall wherein a plurality of fuel exit portions defines the crenellated wall. The burner base includes a peripheral wall. The at least one annular burner cap is coupled to the peripheral wall of the burner base and is positioned on the crenellated wall.

Abstract: A burner unit includes first and second burner assemblies supplied with a gas mixture via first and second valves, respectively. A first valve control assembly controls the first and second valves between open and closed positions. Third and fourth burner assemblies of the burner unit are supplied with a gas mixture via third and fourth valves, respectively. A second valve control assembly controls the third and fourth valves between open and closed positions. The first and second valve control assemblies are separate assemblies that are configured to cooperate to simultaneously provide a gas mixture to the first, second, third and fourth burner assemblies in respective high power settings of the first and second valve control assemblies.

Abstract: A fuel-burning cooking burner includes a base defining an outer periphery and an inner open area. The burner further includes a cap coupled with the base around the outer periphery thereof and extending over the open area to define a distribution cavity on an interior side of the cap. The cap further defines a convex outer surface extending opposite the distribution cavity and a plurality of outlets extending through the cap from the distribution cavity to the exterior surface. The outlets are distributed over the entire exterior surface.

Abstract: A gas burner having a switchable flame includes a combustion chamber having a bottom and a circumferential crenellated wall with a plurality of fuel exit ports disposed in the circumferential crenellated wall. The fuel exit ports are directed generally inwardly toward the combustion chamber and also upwardly from the bottom of the combustion chamber. The gas burner additionally includes a burner base and a swirl spreader disposed above the burner base which defines a top portion of the circumferential crenellated wall of the combustion chamber. An annular burner cap set includes an inner flame burner cap and a vertical flame burner cap where the inner flame burner cap and the vertical flame burner cap are selectively and alternatively positioned on the circumferential crenellated wall to define an inner flame state and a vertical flame state, respectively, of the fuel exit ports.

Abstract: A gas burner for a cooking appliance includes a body defining perimeter and having a plurality of first groups of respective pluralities of first outlets a plurality of second groups of respective pluralities of second outlets. Each of the first outlets respectively defines a first outlet area, and each of the second outlets defines respective reduced outlet areas that are less than the first outlet area. Further, the first groups and second groups are alternately arranged around the perimeter, and a total number of first outlets is greater than a total number of second outlets.
