Abstract (en)
[origin: EP0401583A1] In a fume extractor hood (5) for cooking areas or other sources of dust or fumes, a blower nozzle arrangement (26) is provided on the front edge (27) of the hood which directs blown air (22) in the form of a wall jet approximately horizontally over the underside of the hood (28) against a filter (17) arranged in the rear hood region, so that the wall jet aspirates and entrains the flow of fumes. In a specific embodiment of the fume extractor hood, a downward-directed swirl nozzle (38) is provided on the underside of the front wall of the hood and generates a turbulent flow (37) which enters the flow of blown air. <IMAGE>
