Eine Vorrichtung mit den eingangs beschriebenen Merkmalen ist aus der Druckschrift DE 198 34 341 C2 bekannt. Bei der bekannten Vorrichtung weisen die Antriebswelle und die Nabe eine Axialbohrung für die Zuführung des Luftstromes auf. Der zugeführte Luftstrom vermischt sich innerhalb eines glockenförmigen Leitelementes mit dem über Einströmöffnungen angesaugten Wasserstrom. Zum Ansaugen des Luftstromes wird ein Venturieffekt ausgenutzt, der aus einer Beschleunigung des Wassers durch die Propellerflügel und einem damit einhergehenden lokalen Unterdruck im Bereich der Nabe resultiert. Entsprechend ist die Luftzufuhr durch das Ausmaß des lokalen Unterdruckes an der Propellernabe limitiert.A device with the features described above is known from the document DE 198 34 341 C2. In the known device, the drive shaft and the hub on an axial bore for the supply of air flow. The supplied air stream mixes within a bell-shaped guide element with the intake via the intake water flow. For sucking the air flow, a Venturi effect is exploited, which consists of an acceleration of the water through the propeller blades and a concomitant local negative pressure in the hub results. Accordingly, the air supply is limited by the extent of the local negative pressure at the propeller hub.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung mit den eingangs beschriebenen Merkmalen anzugeben, die sich durch eine verbesserte Zufuhr von Umgebungsluft auszeichnet.The invention has for its object to provide a device with the features described above, which is characterized by an improved supply of ambient air.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass innerhalb des Luftkanals der Nabe Gebläseschaufeln zur Luftförderung angeordnet sind. Erfindungsgemäß erfüllt der Luftkanal die Funktion eines Gebläses, das durch die Propellerrotation zu einer Erhöhung des aus der Umgebung angesaugten Luftvolumenstromes führt. Der Luftkanal ist vorzugsweise ringförmig und konzentrisch zur Nabenachse ausgebildet. Die ringförmige Gestaltung des Luftkanals erlaubt eine sehr feine Verteilung der angesaugten Luft in dem der Sanitärwanne zugeführten Wasserstrom. Darüber hinaus trägt auch der durch die Gebläseschaufeln erzeugte Drall der Luftströmung zu einer intensiven Vermischung von Luft und Wasser bei. Vorzugsweise ist der Propeller als einstückiges Spritzgussteil aus Kunststoff ausgebildet, welches mit geringem fertigungstechnischen Aufwand herstellbar ist.The object is achieved in that within the air duct of the hub fan blades are arranged for conveying air. According to the invention, the air duct fulfills the function of a blower, which leads by the propeller rotation to an increase in the volume of air drawn in from the surroundings. The air duct is preferably annular and concentric with the hub axle. The annular design of the air duct allows a very fine distribution of the sucked air in the sanitary tub supplied water flow. In addition, the swirl generated by the fan blades of the air flow contributes to an intensive mixing of air and water. Preferably, the propeller is designed as a one-piece injection molded part made of plastic, which can be produced with little manufacturing effort.

Vor der Lufteinströmöffnung des Strömungskanals kann ein Rückflussverhinderer vorgesehen sein, an den stromauf ein Lufteintrittsstutzen angeschlossen ist. Die Luftzufuhr ist vorzugsweise durch einen an ein Bedienelement angeschlossenes Ventil bzw. durch einen separaten Drehknopf wahlweise zu- und abschaltbar.In front of the air inflow opening of the flow channel, a backflow preventer can be provided, to which an air inlet connection is connected upstream.

Innerhalb des Innenkranzes sind zweckmäßigerweise Strömungsführungselemente angeordnet, die zu einer Gleichrichtung der Strömung beim Durchströmen der Durchlassöffnung beitragen. Der Leitschaufelkranz kann schwenkbeweglich zur Nabenachse angeordnet sein. Hierdurch ist es möglich, den Luft-/Wasserstrom in eine gewünschte Richtung beim Einströmen in die Badewanne zu lenken. Der Leitschaufelkranz weist zweckmäßigerweise eine ringförmige Lagerschale auf, die mit einem an der Aufnahmevorrichtung angeordneten Kugeloberflächensegment ein Kugelgelenk bildet. Gleichzeitig liegt der Leitschaufelkranz randseitig an der der Sanitärwannenwandung zugewandten Seite der Rosette an. Die Schwenkposition kann durch Druck auf den Leitschaufelkranz verändert werden, wobei der Leitschaufelkranz aufgrund seines elastischen Verhaltens in der gewünschten Position verharrt.According to a particularly preferred embodiment of the invention, a guide vane ring is arranged in the outlet opening. The vane ring may have an inner ring with a central passage opening, to which the Guide vanes are formed on the outside. Within the inner ring flow guide elements are expediently arranged, which contribute to a rectification of the flow when flowing through the passage opening. The vane ring may be pivotally mounted to the hub axle. This makes it possible to direct the air / water flow in a desired direction when flowing into the bathtub. The vane ring expediently has an annular bearing shell which forms a ball joint with a ball surface segment arranged on the receiving device. At the same time, the vane ring rims against the side of the rosette facing the sanitary sump wall.
