Abstract

The hot water mixing valve is connected to the cold and hot water supply and supplies a mixed water outlet tap. The mixing valve can be connected directly to the cold and hot water supply without additional return flow obstructions. The tap has a housing (10) with a T-shaped part (12). This T-junction is connected directly between a cold water pipe and cold water connection (4) of the hot water tank. The T-junction is also connected by a housing tube (24) directly to a cruciform mixing arrangement, connected directly between the hot water connection (6) of the hot water tank (2) and mixed water tap.

Description

Thermomischer mit einem geschlossenen Auslauf zum Anschluss anThermal mixer with a closed outlet for connection to

einen Warmwasserbereiter Die Erfindung betrifft einen Thermomischer mit einem geschlossenen Auslauf, zum Anschluss an den Kaltwasseranschluss und den Warmwasseranschluss eines Warmwasserbereiters und zur Versorgung mindestens einer Mischwasserzapfstelle. a water heater The invention relates to a thermal mixer with a closed outlet, for connection to the cold water connection and the Hot water connection of a water heater and for supplying at least one Mixed water tap.

Bei Thermomischern mit geschlossenem Auslauf muss heute nach den Vorschriften des Schweiz. Vereins von Gas- und Wasserfachmännern die Kaltwasserleitung zur Mischarmatur zwischen Warmwasserbereiter und dessen Rückflussverhinderer angeschlossen werden. Zudem müssen in die Kalt- und Warmwasserleitungen vor der Mis charmatur zusätzliche RückSlussverhinderer eingebaut werden, um ein eventuelles Ueberströmen von Warmwasser in die Kaltwasserleitung, oder von Kaltwasser in die Warmwasserleitung zu verhindern. Alle diese Massnahmen sind teuer und beinhalten zusätzliche Störquellen. Ueberdies ist eine solche Anordnung unschön.Thermal mixers with a closed outlet must now comply with the regulations of Switzerland. Association of gas and water specialists the cold water pipe to the mixer tap be connected between the water heater and its backflow preventer. In addition, additional pipes must be installed in the cold and hot water pipes before the mixer Non-return valves are installed to prevent any overflow of hot water in the cold water pipe, or to prevent cold water in the hot water pipe. All of these measures are expensive and contain additional sources of interference. Moreover such an arrangement is ugly.

Aufgabe der Erfindung ist es, einen Thermomischer mit geschlossenem Auslauf zu schaffen, der ohne zusätzliche Rückflussverhinderer direkt an den Kalt- und Warmwasser-Anschlüssen eines Warmwasserbereiters anschliessbar ist und der die genannten Nachteile nicht aufweist.The object of the invention is to provide a thermal mixer with a closed To create an outlet that connects directly to the cold and hot water connections of a water heater can be connected and the does not have the disadvantages mentioned.

Der eingangs genannte erfindungsgemässe Thermomischer ist dadurch gekennzeichnet, dass er ein Gehäuse aufweist, welches einen T-förmigen Gehäuseteil enthält, der direkt zwischen einer Kaltwasserleitung und dem Kaltwasseranschluss des Warmwasserbereiters anschliessbar ist und der mittels eines Gehäuserohres direkt mit einem kreuzförmigen, eine Mischvorrichtung enthaltenden, Mischergehäuseteil verbunden ist, welcher direkt zwischen dem Warmwasseranschluss des Warmwasserbereiters und der Mischwasserzapfstelle anschliessbar ist.The inventive thermal mixer mentioned at the outset is thereby characterized in that it has a housing which has a T-shaped housing part that is located directly between a cold water pipe and the cold water connection of the water heater can be connected and that by means of a housing pipe directly with a cross-shaped mixer housing part containing a mixing device connected directly between the hot water connection of the water heater and the mixed water tap can be connected.

Durch diese neuartige Ausbildung des Gehäuses des Thermomischers ist es möglich, den Thermomischer direkt zwischen den Anschlüssen des Warmwasserbereiters und der Kaltwasserleitung einerseits und der Mischwasserzapfstelle andererseits anzuordnen. Dadurch sind die beiden im bekannten Falle zusätzlichen Rückflussverhinderer an den Kalt- und Warmwasser-Anschlüssen des Thermomischers nicht mehr erforderlich.This novel design of the housing of the thermal mixer is it is possible to place the thermal mixer directly between the connections of the water heater and the cold water pipe on the one hand and the mixed water tap on the other to arrange. As a result, the two are additional backflow preventer in the known case no longer required on the cold and hot water connections of the thermal mixer.

Ein Ausführungsbeispiel des erfindungsgemässen Thermomischers wird anhand der Zeichnung nachfolgend näher beschrieben.An embodiment of the inventive thermal mixer is described in more detail below with reference to the drawing.

Die Zeichnung zeigt einen Warmwasserbereiter 2 mit einem Kaltwasseranschluss 4 und einem Warmwasseranschluss 6, an die ein Thermomischer 8 angeschlossen ist.The drawing shows a water heater 2 with a cold water connection 4 and a hot water connection 6, to which a thermal mixer 8 is connected.

Der Thermomischer 8 enthält ein Gehäuse 10, das einen T-förmigen Gehäuseteil 12 aufweist, er über einen Gewindestutzen 14 mit einer schematisch angedeuteten Kaltwasserleitung 16 verbindbar ist. In letzterer ist ein Rückflussverhinderer 18 angeordnet. Das sich beim Aufheizen des Warmwasserbereiters 2 ausdehnende Wasser kann sich über ein Sicherheitsventil 20 entspannen. Der Thermomischer 8 ist ferner mittels einer Verschraubung 22 direkt an dem Kaltwasseranschluss 4 angeschlossen. Der T-förmige Gehäuseteil 12 ist überdies mittels eines Gehäuserohres 24 direkt mit einem kreuzförmigen Mischergehäuseteil 26 verbunden. Letzterer ist über eine Verschraubung 28 direkt am Warmwasseranschluss 6 des Warmwasserbereiters 2 angeschlossen. Ferner enthält der Mischergehäuseteil 26 einen Gewindestutzen 30 zum Anschluss an eine oder mehrere, nicht dargestellte Mischwasserzapfstellen. Die nicht näher dargestellte Mischvorrichtung des Mischergehäuseteiles 26 ist von bekannter Bauart und weist einen Drehgriff 32 auf, an dem die gewünschte Mischwassertemperatur, z.B. 500C, eingestellt werden kann.The thermal mixer 8 includes a housing 10 which has a T-shaped housing part 12, it has a threaded connector 14 with a schematic indicated cold water line 16 is connectable. In the latter there is a backflow preventer 18 arranged. The water that expands when the water heater 2 heats up can relax via a safety valve 20. The thermal mixer 8 is also Connected directly to the cold water connection 4 by means of a screw connection 22. The T-shaped housing part 12 is moreover directly by means of a housing tube 24 connected to a cross-shaped mixer housing part 26. The latter is about one Screw connection 28 connected directly to the hot water connection 6 of the water heater 2. Furthermore, the mixer housing part 26 contains a threaded connector 30 for connection to one or more mixed water taps, not shown. The one not shown in detail Mixing device of the mixer housing part 26 is of known design and has a rotary handle 32 on which the desired mixed water temperature, e.g. 500C, can be adjusted.
