ABSTRACT:
A range hood for an enclosure, which may be either ducted or ductless, comprises a hood having an inner compartment, said inner compartment having an air inlet aperture and first and second air outlet apertures; a blower means disposed within said hood and adapted to draw air from said enclosure through said air inlet aperture into said inner compartment and to discharge the air from said inner compartment through said outlet apertures; a damper member mounted for movement between a first position blocking said first outlet aperture, sand a second position not blocking said first outlet aperture, said damper member being normally biased to said first, blocking position; a first means for selectively locking or unlocking said damper member in said first position; and a second means for selectively opening or closing said second outlet aperture, such that, when said second outlet aperture is open and said damper member is locked in said first position, the air drawn into said inner compartment by said blower means is discharged therefrom through said second outlet aperture and, when said second outlet aperture is closed and said damper member is not locked in said first position, the air drawn into said inner compartment by said blower means moves said damper member to said second position and is discharged out of said first outlet aperture.
