Description

Beim Öffnen des Warmwasserhahnes läuft bis zum Erreichen der Warmwassertemperatur eine bestimmte Menge Frischwasser zum Schmutzwasser. Um diese Verschwendung von Trinkwasser zu vermeiden, sollte eine Brauchwasser Spareinheit eingebaut werden.When opening the Hot water tap is running up to reach the hot water temperature a certain amount of fresh water to the dirty water. To avoid this waste of drinking water, should a service water saving unit be installed.

Die im Schutzanspruch angegebene Erfindung liegt das Problem der Trinkwasserverschwendung an Warmwasserentnahmestellen zu Grunde.The in the protection claim specified invention is the problem of drinking water waste based on hot water taps.

Dieses Problem wird mit dem im Schutzanspruch aufgeführten Merkmalen vermieden.This Problem is avoided with the features listed in the protection claim.

Mit der Erfindung kann je nach Leitungslänge und Querschnitt bis zu 200,0 EUR im Jahr an Wasser- und Abwasserkosten eingespart werden. Das würde nicht nur Geld sparen sondern auch der Umwelt zu Gute kommen.With The invention can be up to depending on the length of the cable and cross section 200.0 EUR per year in water and wastewater costs are saved. That would not only save money but also benefit the environment.

Funktionsbeschreibungfunction Description

Der Warmwasserhahn (1) am Wasserverbraucher wird geöffnet. Bei einer Mischbatterie ist die Hebelstellung auf warm eingestellt. In der Eingebauten Spareinheit schließt das Temperaturventil (2) bis 29°C Und das Ventil (3) bis 30°C öffnet sich. Das anströmende Kaltwasser aus der Warmwasserleitung läuft über die Leitung mit dem Ventil (3) in den Rückhaltebehälter. Ist die Warmwassertemperatur auf 30°C angestiegen, schließt das Ventil (3) und das Ventil (2) öffnet sich. Heißes Wasser strömt zur Mischbatterie und öffnet gleichzeitig den Kaltwasserstrom. Das kalte Wasser fließt über eine Wasserstrahlpumpe und saugt den Rückhaltebehälter wieder leer. Ist der Behälter leer, schleißt das Schwimmerventil (6) die Saugleitung der Wasserstrahlpumpe. Das Schwimmerventil (5) sorgt für die Be- und Entlüftung des Rückhaltebehälters. Die Absperrventile (8) sind die vorhandenen Eckventile in der Hausinstallation.The hot water tap ( 1 ) at the water consumer is opened. For a mixer tap, the lever position is set to warm. In the built-in economy unit closes the temperature valve ( 2 ) to 29 ° C and the valve ( 3 ) to 30 ° C opens. The inflowing cold water from the hot water pipe runs via the line with the valve ( 3 ) in the retention container. When the hot water temperature has risen to 30 ° C, the valve closes ( 3 ) and the valve ( 2 ) opens. Hot water flows to the mixer tap and simultaneously opens the cold water flow. The cold water flows through a water jet pump and sucks the retention tank empty again. If the container is empty, the float valve ( 6 ) the suction line of the water jet pump. The float valve ( 5 ) ensures the ventilation of the retention tank. The shut-off valves ( 8th ) are the existing angle valves in the house installation.
