  • Patent number: 4418615
    Abstract: An energy efficient convection barbecue pit for uniform cooking of meat. Heated smoke from a firebox passes through a joinder flue into a cooking chamber and is there urged upward by means of an inlet baffle. A convection fan located within a discharge duct connected to the ceiling of the cooking chamber draws the entering smoke through a suction port and discharges it through the duct. The discharge duct channels the smoke toward the front of cooking chamber and then downward thereby creating a turbulent, rolling air flow motion and a uniform temperature profile within the cooking chamber. Exhaust smoke exits at the bottom of the cooking chamber on either side of the inlet baffle and collects in a plenum chamber before exiting through an exhaust stack. Temperature within the cooking chamber is monitored by a thermostatically controlled firebox damper on the firebox door and a thermostatically controlled gas burner adjacent to the firebox.
