Edelstahl-Wasserauslaufrohr mit im Perlator integriertem Opto-Sensor im konkav gestalteten Wasserauslauf.Stainless steel water outlet pipe with opto-sensor integrated in the aerator in the concave water outlet.

Wasserauslaufrohre mit integriertem Opto-Sensor nach dem derzeitigen Stand der Technik weisen entweder einen direkt im Wasserauslauf angebrachten Opto-Sensor oder einen von der Wasserführung getrennt angebrachten Opto-Sensor ■ auf. Beiden Bauartvarianten ist gemein, daß sich der Wasserauslauf und die Oberfläche des Opto-Sensors auf der gleichen Ebene befindet, so daß der Opto-Sensor durch austretendes Wasser befeuchtet wird und sich an der Oberfläche des Opto-Sensors regelmäßig Feuchtigkeit sammelt, die die Funktionsweise des Sensors beeinträchtigt.Water outlet pipes with integrated opto-sensors according to the current state of the art have either an opto-sensor installed directly in the water outlet or an opto-sensor installed separately from the water supply. Both design variants have in common that the water outlet and the surface of the opto-sensor are on the same level, so that the opto-sensor is moistened by escaping water and moisture regularly collects on the surface of the opto-sensor, which impairs the functionality of the sensor.

Die in den Schutzansprüchen beschriebene Erfindung scheidet diese Beeinträchtigung der Funktionsweise des im Wasserverlauf integrierten Opto-Sensors aus, denn der Opto-Sensor ist zentriert in dem konkav konstruierten, mit einem Perlator versehenen Wasserauslauf angebracht.The invention described in the claims eliminates this impairment of the functioning of the opto-sensor integrated in the water flow, because the opto-sensor is mounted centrally in the concavely constructed water outlet provided with an aerator.

Die Funktionsbeeinträchtigung des Opto-Sensors wird mit dem in den Schutzansprüchen aufgeführten Merkmal des räumlich oberhalb des Wasseraustrits angebrachten Opto-Sensors gelöst.The functional impairment of the opto-sensor is solved with the feature listed in the protection claims of the opto-sensor being installed spatially above the water outlet.
