Abstract
Bei einem Verfahren zur Optimierung der Luftführung in einer wenigstens eine Arbeitsöffnung aufweisenden Reinluft-Kabine mit einer horizontal angeordneten Arbeitsplatte (9) und mit wenigstens einem die Arbeitsöffnung (2) der Reinluft-Kabine abschirmenden, durch Einblasen von Reinluft über Leitdüsen (21) erzeugten Reinluftschirm (24), der an der den Leitdüsen (21) gegenüberliegenden Seite der Reinluft-Kabine abgesaugt wird, ist vorgesehen, daß in einem unmittelbar über der Arbeitsfläche der Arbeitsplatte (9) befindlichen Bereich ein Reinluftpolster dadurch erzeugt wird, daß diesem Bereich zusätzliche Reinluft zugeführt wird.In a method for optimizing the air flow in a at least one working opening clean air cabin with a horizontally arranged worktop (9) and with at least a shielding the working opening (2) of the clean air cabin, generated by blowing clean air through guide nozzles (21) Clean air screen (24) on the opposite of the guide nozzles (21) Side of the clean air cabin is vacuumed, it is provided that in a directly above the work surface of the Worktop (9) located area a clean air cushion is generated that this area additional clean air is fed.
Eine insbesondere zur Durchführung des Verfahrens vorgesehene Reinluft-Kabine ist mit einer ein Reinluftpolster unmittelbar über der Arbeitsfläche der Arbeitsplatte (9) erzeugenden Zuleitungseinrichtung für zusätzliche Reinluft ausgerüstet. A clean air cabin, which is provided in particular for carrying out the method, is equipped with a supply device for additional clean air, which produces a clean air cushion directly above the work surface of the worktop (9).
