System and Method for Bimodal Air Control in a Kettle-style Grill

A bimodal air control system, the system comprising:

• means for removably mounting a plenum over an underside surface of a kettle-styled grill, wherein the kettle-styled grill comprises one or more damper holes in the underside surface and one or more damper blades corresponding to the one or more damper holes;
• means for manually adjusting an intake damper located in a side surface of the plenum;
• means for simultaneously adjusting the one or more damper blades when adjusting the intake damper;
• electromechanical means for generating a positive air flow into the plenum;
• and
• means for capturing ash exiting the kettle-styled grill through the one or more damper holes and falling through the plenum;
• wherein when the intake damper is in a fully closed state, the one or more damper blades are positioned such that the one or more damper holes are in an open state;
• and
• wherein when the intake damper is in a partially open state, the one or more damper blades are positioned such that the one or more damper holes are in a partially open state;
• and
• wherein when the intake damper is in a fully open state, the one or more damper blades are positioned such that the one or more damper holes are in a closed state.

A method for bimodal air control in a kettle-styled grill, the method comprising:

• mounting a plenum over an underside surface of a kettle-styled grill, wherein the plenum comprises an adjustable intake damper and the kettle-styled grill comprises one or more damper holes in the underside surface and one or more damper blades corresponding to the one or more damper holes;
• removably mounting an ash to the plenum for capturing ash exiting the kettle-styled grill through the one or more damper holes;
• providing a mechanical connection between the manually adjustable intake damper and the one or more damper blades;
• configuring an electric fan to generate a positive air flow into the plenum;
• manually adjusting the intake damper, wherein:
• when the intake damper is in a fully closed state, the one or more damper blades are positioned such that the one or more damper holes are in an open state;
• and
• when the manually adjustable intake damper is in a partially open state, the one or more damper blades are positioned such that the one or more damper holes are in a partially open state;
• and
• when the manually adjustable intake damper is in a fully open state, the one or more damper blades are positioned such that the one or more damper holes are in a closed state.
