ABSTRACT:
A kitchen exhaust system has an outside air supply blower and a hood exhaust blower discharging outside the building. Air is introduced from the supply blower into the area behind the cooking unit and the exhaust is taken through a removable flow director or guide secured to the typical exhaust hood. The flow guide has an inlet located toward the front of the cooking unit and relatively near the top of the cooking unit and has convenient release devices to facilitate removal of the guide from the hood to facilitate removal and replacement of filters or grease removing devices from their usual disposition in the hood assembly. The shape of the flow director is such as to provide a high velocity of the fluid flow adjacent the intake opening and thereby provide more effective scavenging action for combustion products and cooking fumes than is typically found with an exhaust unit unassisted by the flow director of the present invention.
