Under Cabinet Ventilation System

Abstract

A ventilation system comprising a plenum below the lower shelf of a cabinet combined with ductwork and special fan applications designed to evacuate air from the interior to the exterior of a building. The system is designed to eliminate issues normally encountered when retrofitting a ventilation system into an existing building.

1 ) A ventilation system comprising a plenum created below a lower shelf of a cabinet and above a floor of a building and bordered by four vertical sidewalls comprising said cabinet, said ventilation system including ductwork encompassing an opening created in an area of said floor which will provide entry into said plenum, said ductwork including mounting facility to allow attachment to said floor, said ductwork connected to an electric fan operated by adjustable electronic controls, said fan providing evacuation of air from said plenum to the exterior of said building. 
     
     
         2 ) The ventilation system of  claim 1  wherein said mounting facility comprises a flange included on said ductwork to facilitate screw or nail type mounting hardware to allow attachment to a surface of said floor. 
     
     
         3 ) The ventilation system of  claim 1  wherein said ductwork mounting facility comprises a flexible seal sufficient to secure said ductwork within said opening. 
     
     
         4 ) A ventilation system comprising a plenum created below a lower shelf of a cabinet and above a floor of a building and bordered by four vertical sidewalls comprising said cabinet, said ventilation system including ductwork encompassing an opening created in said lower shelf of said cabinet, said ductwork including mounting facility to allow attachment to said shelf, said ductwork connected to an electric fan operated by adjustable electronic controls, said fan providing evacuation of air from said plenum to the exterior of said building. 
     
     
         5 ) The ventilation system of  claim 4  wherein said mounting facility comprises a flange included on said ductwork to facilitate screw or nail type mounting hardware to allow attachment to a surface of said shelf. 
     
     
         6 ) The ventilation system of  claim 4  wherein said ductwork mounting facility comprises a flexible seal sufficient to secure said ductwork within said opening. 
     
     
         7 ) A ventilation system comprising a plenum created below a lower shelf of a cabinet and above a floor of a building and bordered by four vertical sidewalls comprising said cabinet, said ventilation system including ductwork encompassing an opening created in an area of said floor which will provide entry into said plenum, said ductwork including mounting facility to allow attachment to said floor, said ductwork connected to a pipe supplying combustion air for a high efficiency furnace, an exhaust blower motor of said furnace providing air evacuation of said plenum. 
     
     
         8 ) The ventilation system of  claim 7  wherein said mounting facility comprises a flange included on said ductwork to facilitate screw or nail type mounting hardware to allow attachment to a surface of said floor. 
     
     
         9 ) The ventilation system of  claim 7  wherein said ductwork mounting facility comprises a flexible seal sufficient to secure said ductwork within said opening.
