Durch die Pumpe lässt sich bei vorgegebenem Ablaufrohrinnen- durchmesser von z.B. 34 mm oder 44 mm die Ablaufleistung gegenüber derjenigen eines herkömmlichen Ablaufs, der ausschließlich nach dem Prinzip der Schwerkraftentwässerung funktioniert, erheblich steigern. The inventive process is characterized in that its drain housing is provided with a pump for conveying water in the direction of the outlet. By means of the pump, for a given drain pipe internal diameter of, for example, 34 mm or 44 mm, the drainage performance can be significantly increased compared to that of a conventional drain, which operates exclusively on the principle of gravity drainage.
Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Ablaufs sieht vor, dass die Pumpe mit einem hydraulischen Antrieb versehen ist. Diese Ausgestaltung ermöglicht die Nutzung der Energie des in die Dusche bzw. den Nassraum zulaufenden An advantageous embodiment of the sequence according to the invention provides that the pump is provided with a hydraulic drive. This embodiment allows the use of the energy of the shower or the wet room tapered
Wassers zur Beschleunigung des ablaufenden Wassers. Hierzu werden keine zusätzlichen Steuerungselemente benötigt. Es ergibt sich somit ein Synergieeffekt, der die Energie von zulaufendem Wasser zur Steigerung der Ablaufleistung nutzt. Dieser Effekt lässt sich insbesondere bei Duschen nutzen. Je höher der Volumenstrom des zulaufenden Wassers ist, desto größer ist die Leistung der Pumpe und desto höher ist die Ablaufleistung des erfindungsgemäßen Ablaufs. Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Ablaufs besteht darin, dass die Pumpe aus einem im Ablaufgehäuse gelagerten Pumpenlaufrad gebildet ist, wobei der hydraulische Antrieb ein mit Wasser beaufschlagbares  Water to accelerate the running water. For this purpose, no additional control elements are needed. This results in a synergy effect, which uses the energy of incoming water to increase the drainage performance. This effect can be used especially in showers. The higher the volume flow of the incoming water, the greater the performance of the pump and the higher the drainage performance of the process according to the invention. A further advantageous embodiment of the process according to the invention is that the pump is formed from a pump impeller mounted in the drain housing, wherein the hydraulic drive is acted upon by a water

Magnetkupplung mit dem Pumpenlaufrad gekoppelt ist. DieseMagnetic coupling is coupled to the pump impeller. These
Ausgestaltung bietet hinsichtlich der Montage der Pumpe sowie hinsichtlich der Dichtheit des Ablaufgehäuses Vorteile. Denn zum Antrieb des Pumpenlaufrades wird bei dieser Ausgestaltung keine Antriebswelle benötigt, die sich gegebenenfalls von außen in das Ablaufgehäuse erstrecken und eine Design offers advantages in terms of mounting the pump and in terms of tightness of the drain body. Because to drive the pump impeller, no drive shaft is required in this embodiment, which optionally extend from the outside into the drain housing and a
Wellenabdichtung erfordern würde. Derartige Abdichtungen sind relativ aufwendig. Der erfindungsgemäße Ablauf kommt bei dieser bevorzugten Ausgestaltung ohne eine das Ablaufgehäuse durchdringende Antriebswelle aus. Die Rotation des Shaft seal would require. Such seals are relatively expensive. The process according to the invention is added this preferred embodiment without a drain housing penetrating drive shaft. The rotation of the
Antriebsrades wird durch die Magnetkupplung berührungslos auf das Pumpenlaufrad übertragen. Die zuverlässige Dichtheit des Ablaufgehäuses wird somit nicht beeinträchtigt. Zudem bietet die Magnetkupplung den Vorteil, dass das Pumpenlaufrad zu Reinigungszwecken einfach aus dem Ablaufgehäuse entnommen werden kann. Das Lösen einer mechanischen Wellenverbindung ist bei dieser Ausgestaltung nicht erforderlich. Drive wheel is transmitted by the magnetic coupling contactless to the pump impeller. The reliable tightness of the drain housing is thus not affected. In addition, the magnetic coupling has the advantage that the pump impeller for cleaning purposes can be easily removed from the drain body. The release of a mechanical shaft connection is not required in this embodiment.
Die Magnetkupplung von Pumpenlaufrad und Antriebsrad kann dadurch realisiert sein, dass das Antriebsrad und das The magnetic coupling of pump impeller and drive wheel can be realized in that the drive wheel and the
Pumpenlaufrad mit eingebetteten Magneten versehen sind. Pump impeller are provided with embedded magnets.
Alternativ, und besonders bevorzugt, können das Antriebsrad und das Pumpenlaufrad auch aus magnetisiertem Kunststoff gefertigt sein. Alternatively, and particularly preferably, the drive wheel and the pump impeller can also be made of magnetized plastic.
Das Pumpenlaufrad ist vorzugsweise nach Art des Laufrades einer Kreiselpumpe ausgebildet, besonders bevorzugt als The pump impeller is preferably designed in the manner of the impeller of a centrifugal pump, particularly preferably as
