Burner for a cooking appliance

A cooking appliance comprising:

• a housing defining a cooking cavity;
• and
• a burner in or on the housing sized and arranged so that at least one dimension of the burner is substantially coextensive with a wall of the cooking cavity, the burner further comprising:
• a cavity-facing portion defining a plurality of flame ports arranged in a plurality of flow-sharing groups around a periphery of a combustion surface;
• and
• a housing-facing portion, wherein at least one of the cavity-facing portion or the housing-facing portion is contoured to define an annular void within the burner fluidly coupled to the plurality of flame ports.

A method of producing a burner for a cooking appliance, the method comprising:

• forming a first plate of the burner from sheet metal using a tool so as to include a contour roughly parallel to an edge of the first plate;
• forming a second plate of the burner from the sheet metal using the tool so that the second plate is identical to the first plate;
• forming flame ports in the first plate of the burner, the flame ports arranged in a plurality of flow-sharing groups around a periphery of the first plate;
• rotating one of the first plate or the second plate about an axis to mirror another of the first plate or the second plate;
• and
• coupling the first plate to the second plate to form an annular void in the burner with the flame ports being fluidly coupled to the annular void.
