Abstract A fan-equipped air delivery vent for installation into a structure in order to enhance the flow of air from a heating/cooling system includes a main housing portion arranged as a generally rectangular box having an air entrance side closest to the heating/cooling system main blower and an air exit side closest to the interior of the room or space which receives the heated or cooled air. Positioned across the air exit side of the main housing portion is a covering register panel which is arranged with two sections of air-flow louvers. Positioned across the air entrance side of the main housing portion is an enclosing panel which has three air-entrance apertures positioned therein. Mounted to the enclosing panel and positioned within the main housing portion are three electric fans which are wired in parallel and controlled by an ON-OFF switch and thermostat. Each of the three electric fans is positioned in alignment with a plurality of louvers on the exit side and with one of the three air-entrance apertures on the inlet side. The enclosing panel and the defined air-entrance apertures ensure that virtually all of the air delivered by the heating and cooling system will flow through the three electric fans and that the fans will conduct relatively clean filtered air. The backflow of dirty air across the tips of the fan blades is restricted by the design of the air delivery vent.
In combination: a floor portion of a structure defining a substantially rectangular opening; an air delivery duct extending from below said floor portion in the direction of said opening; and a modular air delivery vent attached to said floor portion and being disposed in said air delivery duct, said air delivery vent comprising: a housing member defining an air entry aperture and including an outlet flow register defining a plurality of outlet air flow passageways; a plurality of fans positioned within said housing member and arranged to increase the air flow rate of air flowing between said air entry aperture and said outlet air flow passageways; and an enclosing panel attached to said housing member and extending across said air entry aperture, each of said plurality of fans being mounted to said enclosing panel, said enclosing panel defining a plurality of air-entrance apertures, there being one air-entrance aperture aligned with each one of said plurality of fans.
