Abstract: A domestic home gas cooktop is provided. The cooktop has a top sheet having a primary combustion air hole through the top sheet; a gas burner cup mounted to the top sheet; and a gas burner base mounted to the burner cup. The primary combustion air hole is configured to allow first primary combustion air to flow from beneath the top sheet to the burner base, and the primary combustion air hole is located remotely from the burner cup.

Abstract: Strategies for providing aesthetically acceptable ventilation for appliances requiring ventilation are described. In one or more implementations, a notch is cut along the upper edge of a cabinet toe kick to allow ambient air to enter and exit an air cavity disposed behind the toe kick. A fence or trim piece is then installed in front of the notch to hide the notch from view and to create a labyrinth vent allowing ambient air to enter and exit the air cavity. This ambient air flow is required for proper operation of appliances requiring ventilation.

Abstract: A cooktop has a top sheet; a space below the top sheet; a first passageway through the top sheet; a second passageway through the top sheet; a first gas burner that draws primary combustion air from the space below the top sheet; a first gas control knob that controls an amount of gas that flows to the first gas burner, the first gas control knob protruding through the first passageway; a second gas burner that draws primary combustion air from the space below the top sheet; and a second gas control knob that controls an amount of gas that flows to the second gas burner, the second gas control knob protruding through the second passageway. The first passageway and the second passageway have different airflow rates at a given negative air pressure in the space below the top sheet.
