Abstract

The heat exchanger (1) has an upper and a lower section joined by a tube through which the used drainage water (a) from the shower tray (7) and siphon (8) into the heat exchanger vessel to the drain outlet (b). Fresh cold water (3) passes through the heat exchanger to a mixer tank (6) also supplied with warm water.

Description

Bei üblich montierten Warmwasserduschen in Haushalten oder Gebäuden fließt das warme Abwasser in den Kanal. Um die gewünschte Duschwassertemperatur einzustellen, ist eine Mischung aus warmen – und kalten Wasser erforderlich. Dies geschieht über Mischergarnituren verschiedener Bauarten.For commonly mounted Hot water showers in households or buildings, the warm wastewater flows into the Channel. To the desired To adjust the shower water temperature is a mixture of hot and cold Water required. This is done by mixer sets of different Types.

Mit der Erfindung wird erreicht, daß das Kalte Wasser, daß an die Mischerbatterie geführt wird, über das noch warme Abwasser vorgeheizt wird. Dem temperierten Abwasser wird Wärme entzogen, und dem kalten Wasser zugeführt.With the invention is achieved that the Cold water, that on led the mixer battery will, over the still warm wastewater is preheated. The tempered wastewater will heat withdrawn, and fed to the cold water.

Der große Vorteil der Erfindung ist, dass dadurch ein großer Teil der Wärmeenergie des Abwassers, die sonst unnütz im Abwasserkanal entsorgt wird an das kalte Zulaufwasser der Dusche zurückgeführt wird. Ferner wird noch Wasser gespart. Mittels einem speziell geformten Abwasserrohr und einem Wasser-Wasser Wärmetauscher wird die Oberfläche des Abwassers im Abwasserrohr erhöht und die Strömungsgeschwindigkeit des Abwassers verlangsamt, so daß sich der Wirkungsgrad der Wärmerückgewinnung erhöht.Of the size Advantage of the invention is that thereby a large part of the heat energy of wastewater, otherwise useless is disposed of in the sewer to the cold inlet water of the shower is returned. Furthermore, water is still saved. By means of a specially shaped Sewer pipe and a water-water heat exchanger will be the surface of the Wastewater in the sewer pipe increased and the flow velocity slows down the effluent, so that the efficiency of the Heat recovery elevated.

Dieses Problem wird mit den im Schutzanspruch aufgeführten Merkmalen gelöst.This Problem is solved with the features listed in the protection claim.
