Abstract (en)

[origin: EP3667176A1] We describe a fume extractor hood (1) comprising a flow generator (2) for providing a forced flow (11) in an active mode of the flow generator (2), an exhaust duct (3) for guiding an exhaust flow (12), a cleaning device (4) for cleaning a recirculation flow (13), and a splitting device (5) for splitting the forced flow (11) in the exhaust flow (12) and the recirculation flow (13). The fume extractor hood (1) is characterized that in the active mode, the splitting device (5) is in a first fixed state with a first opening area (30) to the exhaust duct (3) so that the forced flow (11) is split in the exhaust flow (12) and the recirculation flow (13) through the cleaning device (4). Further, we describe a ventilation system for a house or a building and a method for operating a fume extractor hood (1).
