Description

Die vorliegende Erfindung bezieht sich auf einen Wasserspeicher gemäß dem Oberbegriff des Hauptanspruchs.The present invention relates to a water reservoir according to the preamble of the main claim.

Solche Wasserspeicher dienen in erster Linie zum Bereiten warmen Gebrauchswassers. Sie weisen einen Anschluß zum Zuführen kalten Gebrauchswassers auf,und ihnen kann das erwärmte Gebrauchswasser über ein Zapfventil entnommen werden. Beheizt werden solche Wasserspeicher in der Regel von einem Gasbrenner, der unterhalb des Wasserspeichers angeordnet ist und der das Wasserspeichervolumen an der Unterseite beziehungsweise im Zentrum durch ein hindurchgehendes Abgasrohr erwärmt.Such water reservoirs are primarily used to prepare warm service water. They have a connection for supplying cold service water, and the heated service water can be removed from them via a tap valve. Such water reservoirs are usually heated by a gas burner, which is arranged below the water reservoir and which heats the water reservoir volume on the underside or in the center through an exhaust pipe that passes through.

Es ist auch schon bekanntgeworden, solche Wasserheizer zur Zentralheizung von Räumen heranzuziehen. Hierzu wurde in den Innenraum des Wasserspeichers ein Rohrwendel-Wärmetauscher eingebracht, der mit seinen beiden Anschlüssen an die Zentralheizungsanlage angeschlossen wurde. Der Nachteil hiervon ist, daß der Speicher baulich verändert werden muß, je nachdem, ob er als reiner Brauchwasserspeicher oder als kombinierter Brauchwasserspeicher/Wärmequelle für eine Zentralheizung Verwendung finden soll.It has also become known to use such water heaters for the central heating of rooms. For this purpose, a coiled-tube heat exchanger was installed in the interior of the water storage tank, which was connected to the central heating system with its two connections. The disadvantage of this is that the storage must be structurally changed, depending on whether it is to be used as a pure domestic water storage or as a combined domestic water storage / heat source for central heating.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen ohne bauliche Umgestaltung unversell einsetzbaren Wasserspeicher zu schaffen, der für Brauchwasserzwecke alleine oder auch zusätzlich für die Zwecke einer Heizungsanlage eingesetzt werden kann.The object of the present invention is to provide a water reservoir which can be used without any structural changes and which can be used for process water purposes alone or additionally for the purposes of a heating system.

Die Lösung dieser Aufgabe liegt in den kennzeichnenden Merkmalen des Hauptanspruchs.The solution to this problem lies in the characterizing features of the main claim.

Weitere Ausgestaltung und besonders vorteilhafte Weiterbildung sind Gegenstand der Unteransprüche beziehungsweise gehen aus der nachfolgenden Beschreibung hervor, die ein Ausführungsbeispiel der Erfindung anhand der Figur der Zeichnung näher beschreibt. Die Figur zeigt in schematischer Darstellung einen Schnitt durch den Wasserspeicher mit der nebenstehenden Einheit.A further embodiment and particularly advantageous further development are the subject of the subclaims or emerge from the following description, which describes an exemplary embodiment of the invention with reference to the figure of the drawing.

Neben einem nicht dargestellten wärmeisolierten Gehäuse und einer Aufstellvorrichtung weist der Wasserspeicher einen ringförmigen Wasserspeicherraum 1 auf, der von einer Außenwandung 2 und einer Innenwandung 3 begrenzt ist, wobei die Innenwandung als Flammrohr dient. Der Wasserspeicher ist oben durch einen Deckel 4 und unten durch einen Boden 5 begrenzt, die beide konvex nach oben ausgewölbt sind. Unterhalb des Bodens und ausgerichtet zum Flammrohr 3 ist ein Gasbrenner 6 angeordnet, der über eine Gaszuleitung 7, in der ein Regler 8 angeordnet ist, gespeist ist, wobei ein Temperaturfühler 9 des Reglers in den Wasserspeicherraum 10 hineinragt. Oberhalb des Flammrohrs 3 ist eine Strömungssicherung 11 angeordnet. In das Innere des Wasserraums 10 ist ein Kaltwasserrohr 12 und ein Warmwasser-Zapfrohr 13 eingeführt.In addition to a heat-insulated housing (not shown) and a set-up device, the water reservoir has an annular water storage space 1 which is delimited by an outer wall 2 and an inner wall 3, the inner wall serving as a flame tube. The water reservoir is delimited at the top by a cover 4 and at the bottom by a base 5, both of which are convexly arched upwards. A gas burner 6 is arranged below the floor and aligned with the flame tube 3 and is fed via a gas supply line 7 in which a regulator 8 is arranged, a temperature sensor 9 of the regulator protruding into the water storage space 10. A flow safety device 11 is arranged above the flame tube 3. A cold water pipe 12 and a hot water dispensing pipe 13 are inserted into the interior of the water space 10.

Erfindungsgemäß reichen in den Wasserraum 10 zwei weitere Anschlußstutzen 14 und 15, wobei der eine am oberen, der andere am unteren Ende des Wasserspeichers angeordnet ist.
