Abstract: A ventilation system for use with a cooking appliance to maintain an atmospheric pressure balance existing within an enclosed space surrounding the cooking appliance. A hood establishes a three-dimensional and interiorly recessed configuration and which is supported above the appliance. A filter within the hood communicates with a vacuum driven exhaust extending from the enclosed space. A supply plenum secures in downwardly and opposing fashion relative to a side of the cooking appliance. An air intake communicates the supply plenum with an exterior environment, the plenum including a perforated plate mounted to an inside face thereof in proximity to a bottom closed edge of said plenum and in order to introduce intake air to a side location of the appliance in order to equalize internal pressure and to facilitate upward movement of heated air from the appliance.

A filter within the hood communicates with a vacuum driven exhaust extending from the enclosed space. A supply plenum secures in downwardly and opposing fashion relative to a side of the cooking appliance. An air intake communicates the supply plenum with an exterior environment, the plenum including at least one air flow restricting and redistributing baffle plate and terminating in an upwardly angled outlet for introducing intake air along the side of the appliance, resulting in heating and elevating the intake air within a perimeter defined by the hood and thereby minimizing loss of conditioned air existing within the enclosed space.
