- the invention is therefore based on the object to improve a domestic hot water tank of the type mentioned above in such a way that the internal heater can be arranged as close as possible to the wall of the container bottom and passage openings can be created with an easily realized passage contour.
- the inner heater Due to the miter cut or the miter approach of the pipe section leading out of the interior of the container, it is easily possible to associate the inner heater with its near-ground course part with minimal distance to the floor, the pipe end leading out reaching through the floor vertically or approximately vertically, so that the opening cross-section also can correspond to the pipe cross-section corresponding to a small oversize. This also applies in the event that the interior heater, with its portion running in the area of the floor, is formed spirally to the center of the floor and the connecting end is arranged there in the middle.
- an embossed shape is advantageously provided in the bottom wall of the container in such a way that the embossing is penetrated perpendicularly by the connection end of the inner heater.
- Such an embossing can also be formed as a circular circumferential embossing in the bottom wall, which applies in particular to the case where the inner heater should be a helically coiled inner heater.
- the container bottom can advantageously be provided with a curvature directed into the interior of the container, which ensures that the cold water flowing into its area is automatically distributed outwards to the slightly lower areas of the container bottom.

Abstract
Description
Die Erfindung betrifft einen Brauchwasserspeicher mit Einrichtungen zur Verhinderung des Erhaltes und der Vermehrung von schädlichen Keimen eines in einem aufheizbaren System befindlichen Brauchwasservolumens gemäß Oberbegriff des Hauptanspruches.The invention relates to a process water storage tank with devices for preventing the maintenance and multiplication of harmful germs of a process water volume located in a heatable system according to the preamble of the main claim.
Derartige Brauchwasserspeicher sind bekannt. "Im unteren Bodenbereich angordnet" bedeutet dabei, daß der Innenheizer einerseits mit seinem untersten Teil zwar so dicht wie möglich, also mit relativ geringem Abstand zum unteren Boden des Brauchwasserspeichers angeordnet ist, andererseits steht einer solchen Anordnung aber entgegen, daß der vom Innenheizer abgehende Rücklaufanschluß, der ja aus dem Boden des Speichers herausgeführt werden muß, als Rohrbogen ausgebildet ist, was einen entsprechenden Abstand des Innenheizers vom Boden verlangt, wenn der den Boden durchgreifende Schenkel des Rohrbogens senkrecht oder angenähert senkrecht die Bodenwand durchgreifen soll. Wollte man trotz vorhandenem Rohrbogen den Innenheizer näher an den Boden heranbringen, so würde dies zu einer von der Kreisform abweichenden und relaiv aufwendig herzustellenden Durchgriffsöffnung führen. Eine solche möglichst nahe Zuordnung des Innenheizers zum Boden, um die dort befindliche Kaltwasserschicht voll zu erfassen, ist aber aus Gründen der Verhinderung des Erhaltes und der Vermehrung von schädlichen Keimen (sogenannte Legionellen) anzustreben.Such domestic hot water tanks are known. "Arranged in the lower floor area" means that the inner heater, on the one hand, is arranged as close as possible with its lowermost part, that is, at a relatively short distance from the lower floor of the domestic hot water tank, on the other hand, however, such an arrangement stands in the way that the return connection coming from the inner heater , which must be led out of the bottom of the memory, is designed as a pipe bend, which requires a corresponding distance of the inner heater from the floor if the leg of the pipe bend penetrating the floor is to pass through the bottom wall vertically or approximately vertically. If one wanted to bring the inner heater closer to the floor despite the existing pipe bend, this would lead to a passage opening that deviates from the circular shape and is relatively complex to manufacture. Such an allocation of the internal heater to the floor as close as possible in order to fully capture the cold water layer located there should, however, be attempted in order to prevent the preservation and reproduction of harmful germs (so-called Legionella).
Der Erfindung liegt demgemäß die Aufgabe zugrunde, einen Brauchwasserspeicher der eingangs genannten und bekannten Art dahingehend zu verbessern, daß der Innenheizer mit möglichst kleinem Abstand zur Wand des Behälterbodens angeordnet werden kann und Durchgriffsöffnungen mit einer einfach zu verwirklichenden Durchgriffskontur angelegt werden können.The invention is therefore based on the object to improve a domestic hot water tank of the type mentioned above in such a way that the internal heater can be arranged as close as possible to the wall of the container bottom and passage openings can be created with an easily realized passage contour.
Diese Aufgabe ist mit einem Brauchwasserspeicher der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Hauptanspruches angeführten Merkmale gelöst. Vorteilhafte Weiterbildungen ergeben sich nach den Unteransprüchen.This object is achieved with a domestic hot water tank of the type mentioned according to the invention by the features stated in the characterizing part of the main claim. Advantageous further developments result from the subclaims.
Durch den Gehrungsanschnitt bzw. den Gehrungsansatz des aus dem Behälterinneren herausführenden Rohrstückes ist es ohne weiteres möglich, den Innenheizer mit seinem bodennahen Verlaufsteil mit minimaler Distanz dem Boden zuzuordnen, wobei das herausführende Rohrende den Boden senkrecht bzw. angenähert senkrecht durchgreift, so daß der Öffnungsquerschnitt mit entsprechend geringem Übermaß dem Rohrquerschnitt entsprechen kann. Dies gilt auch für den Fall, daß der Innenheizer mit seiner im Bereich des Bodens verlaufenden Partie spiralförmig zur Mitte des Bodens verlaufend ausgebildet und dort in der Mitte das Anschlußende angesetzt angeordnet ist. Solite für den Innenheizer ein außermittiger Abgang und/oder Zugang vorgesehen sein, so wird vorteilhaft am Boden des Behälters eine Formprägung in der Bodenwand derart vorgesehen, daß die Prägung senkrecht vom Anschlußende des Innenheizers durchgriffen wird. Eine solche Formprägung kann auch als kreisförmig umlaufende Prägung in der Bodenwand ausgebildet sein, was insbesondere für den Fall gilt, daß es sich beim Innenheizer um einen schraubenlinienförmig gewendelten Innenheizer handeln sollte.Due to the miter cut or the miter approach of the pipe section leading out of the interior of the container, it is easily possible to associate the inner heater with its near-ground course part with minimal distance to the floor, the pipe end leading out reaching through the floor vertically or approximately vertically, so that the opening cross-section also can correspond to the pipe cross-section corresponding to a small oversize. This also applies in the event that the interior heater, with its portion running in the area of the floor, is formed spirally to the center of the floor and the connecting end is arranged there in the middle. If an eccentric outlet and / or access is to be provided for the inner heater, then an embossed shape is advantageously provided in the bottom wall of the container in such a way that the embossing is penetrated perpendicularly by the connection end of the inner heater. Such an embossing can also be formed as a circular circumferential embossing in the bottom wall, which applies in particular to the case where the inner heater should be a helically coiled inner heater.
Unabhängig davon, ob es sich beim Innenheiner um einen spiralförmig gewendelten und an den Verlauf des Bodens angepaßten Innenheizer oder einen schraubenlinienförmig gewendelten Innenheizer oder um eine Kombination dieser beiden Innen heizer handelt, kann vorteilhaft der Behälterboden mit einer in das Behälterinnere gerichteten Wölbung versehen sein, die dafür sorgt, daß sich das in deren Bereich einströmende Kaltwasser automatisch nach außen zu den geringfügig tieferliegenden Bereichen des Behälterbodens verteilt. Diese mögliche Ausführungsform ist insbesondere von Interesse für schraubenlinienförmig gewendelte Innenheizer, da mit deren unterem Verlaufsstrang der zentrale Bereich über dem Boden nicht erfaßbar ist.Regardless of whether the interior heater is a spirally coiled interior heater adapted to the shape of the floor or a helically coiled interior heater or a combination of these two interiors the container bottom can advantageously be provided with a curvature directed into the interior of the container, which ensures that the cold water flowing into its area is automatically distributed outwards to the slightly lower areas of the container bottom. This possible embodiment is of particular interest for helical coiled inner heaters, since the central region above the floor cannot be detected with its lower run.
Eine weitere vorteilhafte Ausbildung des Brauchwasserspeichers, bei dem der Innenheizer eine Kombination aus einem spiralförmig gewendelten unteren Teil und einem zylindrisch bzw. schraubenlinienförmig gewendelten Oberteil besteht, besteht darin, daß das vorlaufseitige Anschlußende des spiralförmig gewendelten Teiles des Innenheizers seitlich aus dem zylindrischen oder angenähert zylindrischen Teil des Bodens herausgeführt und im zylindrischen Teil des Behälters der schraubenlinienförmig gewendelte Teil angeordnet und von dessen durch die zylindrische Wand herausgeführten Ende eine äußere Verbindungsleitung zum vorlaufseitigen Anschlußende des spiralförmigen Teiles geführt ist. Hierbei wird nach Maßgabe der Erfindung das Anschlußende des spiralförmig gewendelten Teiles zum darüber befindlichen oberen Teil des Innenheizers seitlich aus dem Behälterboden herausgeführt. Gleiches kann für die Anschlußenden des zylindrisch gewendelten Innenheizers vorgesehen werden, ist dort aber nicht zwingend notwendig, da der obere Teil des Innenheizers durchaus mit einem ausreichenden Abstand zur zylindrischen Wand des Behälters angeordnet sein kann, so daß es möglich ist, für dieses Teil in bekannter Weise die Enden dieses Teiles mit herkömmlichen Rohrbogenanschlüssen zu versehen.Another advantageous embodiment of the domestic hot water tank, in which the internal heater is a combination of a spirally coiled lower part and a cylindrical or helically coiled upper part, is that the lead-side connection end of the spirally coiled part of the inner heater is laterally made of the cylindrical or approximately cylindrical part led out of the bottom and arranged in the cylindrical part of the container of the helically coiled part and from the end led out through the cylindrical wall an outer connecting line is led to the lead-side connection end of the spiral part. Here, according to the invention, the connection end of the spirally coiled part to the upper part of the inner heater located above is led out laterally from the bottom of the container. The same can be provided for the connection ends of the cylindrically coiled inner heater, but is not absolutely necessary there, since the upper part of the inner heater can be arranged at a sufficient distance from the cylindrical wall of the container, so that it is possible for this part to be known Way to provide the ends of this part with conventional elbow connections.
Der erfindungsgemäße Brauchwasserspeicher wird nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erlätuert.The domestic hot water tank according to the invention is explained in more detail below with reference to the drawing of exemplary embodiments.

Wie aus den Fig. 1, 2 ersichtlich, ist das rücklaufanschlußseitige Ende 1 des Innenheizers 2 mit einem 45°-Gehrungsschnitt 3 versehen, wobei das mit einem entsprechenden Gehrungsschnitt 3 versehene Anschlußende, das den Boden 5 des Behälters 6 flüssigkeitsdicht durchgreift, am Ende 1 des Innenheizers 2 angesetzt ist. Wie aus Fig. 5 ersichtlich, kann dabei ohne weiteres ein solcher Gehrungsanschluß auch am vorlaufseitigen Ende 1′ eines solchen spiralförmig gewendelten Innenheizers vorgesehen sein und zwar unabhängig davon, ob im Speicherbehälter 6 nur ein solcher Innenheizer angeordnet oder diesem ein weiterer, zylindrisch gewendelter Innenheizer 2′ vorgeschaltet ist. Diese Gehrungsausbildung ersetzt also die sonst üblichen und Raum- und Wanddistanz erfordernden Rohrbögen, die einer möglichst wandnahen Anordnung der Innenheizer, wie dargestellt, entgegenstünden.As can be seen from FIGS. 1, 2, the return connection end 1 of the
Sofern außermittige Abgänge der Innenheizer 2, 2′ vorgesehen sind, ist gemäß Fig. 2 am Beispiel eines zylindrisch gewendelten Innenheizers 2′ am Boden 5 des Behälters 6 eine Formprägung 7 in der Bodenwand 8 derart angeordnet, daß die Prägung 7 senkrecht vom Anschlußende 4 durchgriffen werden kann. Unter "senkrecht" ist dabei zu verstehen, daß das mit Gehrung angesetzte Anschlußende, wie dargestellt, senkrecht nach unten abgeht, es ist aber auch möglich, ebenfalls mit Gehrung angesetzt, das Ende 4, wie gestrichelt angedeutet, seitlich aus der vertikalen Wand der Prögung 7 herauslaufen zu lassen, wobei sich dann das Ende 4 etwa in der gleichen Ebene wie der unterste Teil des Rohrstranges erstreckt. Insbesondere in Rücksicht auf einen solchen zylindrisch gewendelten Innenheizer 2′ ist die Formprägung 7 gemäß Fig. 3 vorteilhaft als kreisförmig umlaufende Prägung in der Wand 8 des Bodens 5 ausgebildet, wodurch der unterste Strang eines solchen Innenheizers insgesamt noch tiefer dem Boden des Behälters zugeordnet werden kann.If eccentric outlets of the
In diesem Zusammenhang ist es ferner möglich, wie in Fig. 4 dargestellt, den Behälterboden 5 mit einer in das Behälterinnere gerichteten Wölbung 9 zu versehen, wodurch sich die in Fig. 4 im Schnitt dargestellte Bodenform ergibt, der im übrigen auch ein spiralförmig gewendelter Innenheizer entsprechend angepaßt werden könnte. Diese Bodenform hat den Vorteil, daß sich zentrisch zuströmendes Kaltwasser durch die nach innen gerichtete Wölbung 9 zur Seite in den Bereich des Innenheizers verteilt und dort aufgewärmt wird.In this context, it is also possible, as shown in FIG. 4, to provide the
Gemäß Fig. 1 ist das vorlaufseitige Anschlußende 10 des spiralförmig gewendelten Teiles des Innenheizers 2 im Sinne der Ausführungsform gemäß Fig. 5 seitlich aus dem zylindrischen oder angenähert zylindrischen Teil 11 de Bodens 5 herausgeführt, und im zylindrischen Teil 11′ des Behälters 6 ist ein schraubenlinienförmig gewendelter Teil des Innenheizers 2′ angeordnet, von dessen durch die zylindrische Wand herausgeführten Ende 13 eine äußere Verbindungsleitung 14 zum vorlaufseitigen Anschlußende 10 des spiralförmigen Teiles des Innenheizers 2 geführt ist. Der untere Teil des Innenheizers 2 übernimmt hierbei die keimbildungsverhindernde Funktion im Bodenbereich, während der Innenheizer 2′ den wesentlichen Teil der Aufheizung des im Speicherbehälter befindlichen Brauchwassers übernimmt. Durch die Verbindung der beiden Innenheizerteile mittels der äußeren Verbindungsleitung 14 ist die Montage bzw. Zusammenfügung eines solchen Brauchwasserspeichers insofern besonders vorteilhaft, weil damit der un tere Boden mit seinem Innenheizer 2 und der zylindrische Teil mit seinem Innenheizer 2′ separat gefertigt und diese Teile dann problemlos zusammengefügt werden können, wonach lediglich noch die äußere Verbindungsleitung 14 anzubringen ist. Würden beide Innenheizerteile mit einer inneren Verbindungsleitung verbunden sein, so würde dies die Zusammenfügung des Brauchwasserspeichers erschweren.1, the lead-
