  • Publication number: 20220090797
    Abstract: A recirculation grill that includes a cooktop supported by a stationary frame. The grill includes an intake aperture defining a plurality of slats configured for receiving smoke from the cooktop; a waste tray compartment connected to the trough for receiving waste and grease and having a drawer for removing and cleaning; an interior plenum configured to create a vacuum force to pull air and smoke from the cooktop into the intake aperture; a diffuser positioned over the trash compartment and extending downwardly and outwardly; a tunnel configured to receive air flow from the plenum; and a blower housing enclosing a blower fan configured for pulling air and smoke from the cooktop into the intake aperture and through the plenum. The intake aperture, the plenum, and the blower are configured to achieve 100% visible smoke capture.
