Definitions
- the invention relates to a water heater according to the preamble of the main claim.
- a domestic hot water tank of the type mentioned has been proposed according to DE-U-87 03 893 in the priority interval, the storage tank being arranged in the water-carrying housing of a special gas boiler.
- the cold water supply connection is led from below to the bottom of the storage tank and partially designed to be elastic in order to absorb thermal expansion and pressure fluctuations of the storage tank which is only attached to the top of the water-carrying housing and to keep the associated movements away from the weld seams, which would otherwise sooner or later Cracking tend.
- the invention is therefore based on the object to improve a domestic hot water tank of the type mentioned in such a way that such weld seam stresses and weld seam cracks in properly designed welds can be avoided as far as possible safely.
- This design according to the invention is based on the idea of being able to design the part of the cold water connection which extends in the water-carrying interior longer than previously customary in order to accommodate large expansion differences in the storage container, to increase the total bending length and thereby to be able to keep the bending movements at the cold water connection small.
- this design according to the invention not only the entire length of the cold water connection part running in the interior can be increased, but in particular also the corrugated pipe part, of which use is also made here.
- the actual passage and connection point between the cold water connection and the container wall is no longer provided directly on the container wall itself, but a not inconsiderable distance from it, ie the peripheral edge of the passage opening in the container wall is dimensioned so that the relevant one Part of the cold water connection can move freely in it.
- the bottom of the storage tank in the area of the mouth of the cold water connection is provided with an indentation which is perpendicular or approximately perpendicular to the longitudinal axis of the cold water connection Mouth wall has.
- the stretching movements with respect to a weld seam relief are in fact already met, namely at the Container-side connection weld, but it is also advantageously provided to support the storage-base-side and shaft-free end of the cold water connection with a support web extending in the longitudinal direction of the connection against the upper boundary wall of the indentation.
- This support web is simply welded in the appropriate orientation on the one hand to the upper boundary wall of the indentation and on the other hand to the cold water connection pipe.
- a small piece of pipe is advantageously simply arranged on the outside of the container wall above the cross-sectionally round or oval through opening and is connected in a suitable manner in a liquid-tight manner to the container wall, with this in the outlet region of the cold water connection pipe from this piece of pipe having the appropriate shape is liquid-tight connected to the shaft-free line connection end of the cold water connection.
- the through opening is oriented with its main axis parallel to the longitudinal axis of the storage container.
- the domestic hot water tank consists of a storage tank 2 with cold water supply 3 and hot water drainage connection arranged in a heating medium housing 1, the cold water connection 3 connected to the lower floor 4 of the storage tank 2 fixed with its upper part or at least with its hot water discharge pipe in the housing over at least part of its length formed in the form of a corrugated tube 5 and the cold water connection 3 to its exit point from the interior 1 ⁇ of the housing 1 has a length which is greater than the smallest distance between the wall of the storage container 2 and the housing 1 surrounding it Section 5 ⁇ of the cold water connection 3 forms the greater part of its length within the water-carrying Housing interior 1 ⁇ , wherein the cold water connection 3 passes through the housing wall 1 ⁇ in the region of an opening 6 which is larger with respect to its own diameter.
- the part of the cold water connection 3 protruding from the opening 6 extends within a hood-like cover 7 of the opening, ie the interior of this cover 7 also belongs to the interior 1 ⁇ of the housing 1.
- the passage opening edge 8 of the cover 7 is connected to the line connection end region 9 of the cold water connection 3 connected liquid-tight.
- the bottom 4 of the storage tank 2 is provided in the region of the mouth of the cold water connection 3 in the bottom 4 of the storage tank with an indentation 10 which has an orifice wall 12 perpendicular or approximately perpendicular to the longitudinal axis 11 of the cold water connection 3, which facilitates the integration of the shaft-free end of the cold water connection into the floor 4.
- the bottom 13 and shaft-free end 13 of the cold water connection 3 is supported with a support web 14 extending in the longitudinal direction of the connection against the upper boundary wall 15 of the indentation 10. This avoids any stress on the ring weld seam for the integration of the shaft-free end 13.
- the hood-like and relatively long cover 7 of the cross-sectionally round or oval through opening 6 is designed in the form of a tube piece 7 'and suitably connected in a liquid-tight manner to the peripheral edge of the through opening 6 or with a special sheet metal ring on which a connecting flange is formed, but which doesn't matter here.
- This sheet metal ring if present and as shown, must of course then have a corresponding opening aligned with the through opening 6.
- the particular design of the water-carrying housing 1 also shown in this regard is also immaterial, ie the water-carrying housing 1 can be placed under the Bottom 4 of the storage container also form a closed housing, which then is not, as shown, in open connection to a housing of a firing part located under the housing 1.
- the pipe section 7 ⁇ has a length which advantageously corresponds to at least one third of the length of the cold water connection 3 extending in the water-carrying interior 1 ⁇ of the housing 1 and pipe section 7 ⁇ .
- the section 5 Well of the corrugated pipe can also be kept correspondingly long, which means that one is not forced to provide this more or less elastic part of the cold water connection with very tight and tightly folded corrugations. Therefore, the shafts 17 of the corrugated tube 5, as shown in FIG. 2, are advantageously and preferably created with a depth T that is smaller than the wavelength L.
- the accommodation of a relatively long, with a correspondingly long elastic corrugated tube section can also be achieved in that the junction 16 of the container-side end 13 of the cold water connection 3 is arranged opposite or relatively far from the penetration point on the container wall , ie, in this case, the larger part of the cold water connection 3 extends below the bottom 4 of the storage tank.
- the line connection end 9 can then be connected again in a liquid-tight manner to the edge of the passage opening 6, which is then kept correspondingly smaller.
- the arrangement of a hood-like cover 7, as described above, can then be omitted.
- Support webs 14 can, moreover, both in this embodiment and in the embodiment described above also at the line connection end 9 of the cold water connection 3 are provided, that is, either within the cover 7 or in the second case on the container wall.

Description
Die Erfindung betrifft einen Brauchwasserspeicher gemäß Oberbegriff des Hauptanspruches.The invention relates to a water heater according to the preamble of the main claim.
Ein Brauchwasserspeicher der genannten Art ist nach dem DE-U-87 03 893 im Prioritätsintervall vorgeschlagen worden, wobei, wobei der Speicherbehälter im wasserführenden Gehäuse eines speziellen Gasheizkessels angeordnet ist. Bei diesem Brauchwasserspeicher ist der Kaltwasserzufuhranschluß von unten an den Boden des Speicherbehälters herangeführt und teilweise elastisch ausgebildet, um Wärmedehnungen und Druckschwankungen des nur oben im wasserführenden Gehäuse befestigten Speicherbehälters aufnehmen und die damit verbundenen Bewegungen von den Schweißnähten fernhalten zu können, die sonst früher oder später zu Rißbildungen neigen. Da der elastische Teil des Kaltwasseranschlusses zum einen relativ kurz gehalten und zum anderen im Durchgriffsbereich der Gehäusewand unmittelbar mit dieser fest verbunden ist, hat sich gezeigt, daß mit dieser vorbekannten Ausbildung das Problem der Schweißnahtbelastung und daraus resultierender Negativfolgen noch nicht einwandfrei beherrscht werden kann.A domestic hot water tank of the type mentioned has been proposed according to DE-U-87 03 893 in the priority interval, the storage tank being arranged in the water-carrying housing of a special gas boiler. In this domestic hot water tank, the cold water supply connection is led from below to the bottom of the storage tank and partially designed to be elastic in order to absorb thermal expansion and pressure fluctuations of the storage tank which is only attached to the top of the water-carrying housing and to keep the associated movements away from the weld seams, which would otherwise sooner or later Cracking tend. Since the elastic part of the cold water connection on the one hand is kept relatively short and on the other hand is firmly connected to the housing wall in the area of passage, it has been shown that the problem of the weld seam load and the resulting negative consequences cannot yet be mastered properly with this known design.
Der Erfindung liegt demgemäß die Aufgabe zugrunde, einen Brauchwasserspeicher der eingangs genannten Art dahingehend zu verbessern, daß derartige Schweißnahtbelastungen und Schweißnahtrisse an sich einwandfrei angelegter Schweißnähte weitestgehend sicher vermieden werden können.The invention is therefore based on the object to improve a domestic hot water tank of the type mentioned in such a way that such weld seam stresses and weld seam cracks in properly designed welds can be avoided as far as possible safely.
Diese Aufgabe ist mit einem Brauchwasserspeicher der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Hauptanspruches angeführten Merkmale gelöst, und ist außerdem auch gemäß Nebenanspruch 5 lösbar. Vorteilhafte Weiterbildungen ergeben sich nach den Unteransprüchen.This object is achieved with a domestic hot water tank of the type mentioned at the outset according to the invention by the features stated in the characterizing part of the main claim, and can also be achieved in accordance with
Dieser erfindungsgemäßen Ausbildung liegt der Gedanke zugrunde, den sich im wasserführenden Innenraum erstrecktenden Teil des Kaltwasseranschlusses länger als bisher üblich ausbilden zu können, um damit große Dehnungsdifferenzen des Speicherbehälters aufzunehmen, die gesamte Biegelänge zu vergrößern und dadurch die Biegebewegungen am Kaltwasseranschluß klein halten zu können. Durch diese erfindungsgemäße Ausbildung kann nicht nur die gesamte Länge des im Innenraum verlaufenden Kaltwasseranschlußteiles vergrößert werden, sondern insbesondere auch der Wellrohrteil, von dem auch hierbei Gebrauch gemacht wird. Wesentlich ist hierbei, daß die eigentliche Durchgriffs- une Verbindungsstelle zwischen Kaltwasseranschluß und Behälterwand nicht mehr unmittelbar an der Behälterwand selbst vorgesehen ist, sondern ein nicht unbeträchtliches Stück davon entfernt, d.h., der Umfangsrand der Durchgriffsöffnung in der Behälterwand ist so bemessen, daß sich der betreffende Teil des Kaltwasseranschlusses darin frei bewegen kann. Um den Anschluß des speicherbehälterseitigen Endes des Kaltwasseranschlusses einfacher herstellen und auch auf dieser Seite eine größere Länge des Anschlußrohres vorsehen zu können, ist der Boden des Speicherbehälters im Bereich der Einmündung des Kaltwasseranschlusses mit einer Einbuchtung versehen, die eine zur Längsachse des Kaltwasseranschlusses senkrechte oder angenähert senkrechte Einmündungswand aufweist. Durch die größere unterzubringende Länge des Kaltwasseranschlußrohres ist zwar an sich schon den Dehnungsbewegungen bezüglich einer Schweißnahtentlastung entsprochen, und zwar an der behälterseitigen Anschlußschweißnaht, zudem ist aber vorteilhaft vorgesehen, das speicherbodenseitige und wellenfreie Ende des Kaltwasseranschlusses mit einem sich in Längsrichtung des Anschlusses erstreckenden Stützsteg gegen die obere Begrenzungswand der Einbuchtung abzustützen. Dieser Stützsteg wird einfach in entsprechender Orientierung einerseits an der oberen Begrenzungswand der Einbuchtung und andererseits am Kaltwasseranschlußrohr verschweißt. Für die Ausbildung der die Durchgriffsöffnung abschirmenden haubenartigen Abdeckung wird vorteilhaft einfach ein kleines Rohrstück außen an der Behälterwand über der im Querschnitt runden oder ovalen Durchgriffsöffnung angeordnet und in geeigneter Weise flüssigkeitsdicht mit der Behälterwand verbunden, wobei im Austrittsbereich des Kaltwasseranschlußrohres aus diesem Rohrstück dieses bei entsprechender Formgebung mit dem wellenfreien Leitungsanschlußende des Kaltwasseranschlusses flüssigkeitsdicht verbunden ist. Bei ovalem Querschnitt ist die Durchgriffsöffnung mit ihrer Hauptachse parallel zur Längsachse des Speicherbehälters orientiert. Durch die auf diese Weise unterbringbare größere Länge des Kaltwasseranschlußrohres innerhalb des wasserführenden Innenraumes ist es vorteilhaft möglich, einerseits den gewellten Abschnitt des Kaltwasseranschlußrohres länger auszubilden und andererseits die Wellungen flach zu halten, d.h., die Tiefe der Wellen so zu bemessen, daß sie kleiner ist als eine Wellenlänge. Damit sind dichte Wellenfaltungen, wie sie in der Regel für derartige elastische Rohrabschnitte üblich sind, vermeidbar, womit der Gegebenheit Rechnung getragen ist, daß erfahrungsgemäß im unteren Bereich eines Warmwasserspeichers und auch im Rohr für die Kaltwasserzuführung Kalk abgelagert wird, der sich in tiefen bzw. engen Falten des elastischen Rohrstückes insbesondere festsetzen und die Flexibilität dieses Abschnittes zumindest reduzieren würde. Bei den hier vorteilhaft und bevorzugt vorgesehenen flachen Wellungen besteht demgegenüber eine solche Gefahr nicht, d.h., bei relativ flachen Wellen bleibt der ganze Kaltwasseranschluß beweglich und gebrauchsfähig. Bisher ist zwar ausschließlich auf einen Kaltwasseranschluß Bezug genommen, es steht aber grundsätzlich nichts entgegen, dieses neuartige Ausbildungsprinzip auch für Warmwasser- oder andere Rohranschlüsse vorzusehen, soweit diese aufgrund konstruktiver Gegebenheiten entsprechenden Dehnungsbelastungen ausgesetzt sind.This design according to the invention is based on the idea of being able to design the part of the cold water connection which extends in the water-carrying interior longer than previously customary in order to accommodate large expansion differences in the storage container, to increase the total bending length and thereby to be able to keep the bending movements at the cold water connection small. With this design according to the invention, not only the entire length of the cold water connection part running in the interior can be increased, but in particular also the corrugated pipe part, of which use is also made here. It is important here that the actual passage and connection point between the cold water connection and the container wall is no longer provided directly on the container wall itself, but a not inconsiderable distance from it, ie the peripheral edge of the passage opening in the container wall is dimensioned so that the relevant one Part of the cold water connection can move freely in it. In order to make the connection of the storage tank end of the cold water connection easier and to be able to provide a greater length of the connecting pipe on this side, the bottom of the storage tank in the area of the mouth of the cold water connection is provided with an indentation which is perpendicular or approximately perpendicular to the longitudinal axis of the cold water connection Mouth wall has. Due to the larger length of the cold water connection pipe to be accommodated, the stretching movements with respect to a weld seam relief are in fact already met, namely at the Container-side connection weld, but it is also advantageously provided to support the storage-base-side and shaft-free end of the cold water connection with a support web extending in the longitudinal direction of the connection against the upper boundary wall of the indentation. This support web is simply welded in the appropriate orientation on the one hand to the upper boundary wall of the indentation and on the other hand to the cold water connection pipe. To form the hood-like cover shielding the access opening, a small piece of pipe is advantageously simply arranged on the outside of the container wall above the cross-sectionally round or oval through opening and is connected in a suitable manner in a liquid-tight manner to the container wall, with this in the outlet region of the cold water connection pipe from this piece of pipe having the appropriate shape is liquid-tight connected to the shaft-free line connection end of the cold water connection. With an oval cross section, the through opening is oriented with its main axis parallel to the longitudinal axis of the storage container. Due to the larger length of the cold water connection pipe which can be accommodated in this way within the water-carrying interior, it is advantageously possible, on the one hand, to make the corrugated section of the cold water connection pipe longer and, on the other hand, to keep the corrugations flat, ie to measure the depth of the corrugations so that they are smaller than a wavelength. This makes it possible to avoid dense corrugations, as is usually the case for elastic pipe sections of this type, which takes into account the fact that, as experience has shown, lime is deposited in the lower area of a hot water tank and also in the pipe for the cold water supply. tight folds of the elastic pipe piece in particular and would at least reduce the flexibility of this section. In contrast, in the case of the flat corrugations which are advantageously and preferably provided here, there is one No danger, that is, with relatively flat waves, the entire cold water connection remains mobile and usable. So far, reference has been made exclusively to a cold water connection, but there is in principle nothing to prevent this new training principle from also being provided for hot water or other pipe connections, provided that they are exposed to corresponding strain loads due to structural conditions.
Der erfindungsgemäße Brauchwasserspeicher wird nachfolgend anhand der zeichnerischen Darstellung eines Ausführungsbeispiels näher erläutert.The domestic hot water tank according to the invention is explained in more detail below with reference to the drawing of an exemplary embodiment.

Der Brauchwasserspeicher besteht aus einem in einem Heizmedium führenden Gehäuse 1 angeordneten Speicherbehälter 2 mit Kaltwasserzufuhr- 3 und Warmwasserableitungsanschluß, wobei der am unteren Boden 4 des mit seinem Oberteil oder mindestens mit seinem Warmwasserableitungsrohr im Gehäuse fixierten Speicherbehälters 2 angeschlossene Kaltwasseranschluß 3 über mindestens einen Teil seiner Länge in Form eines Wellrohres 5 ausgebildet und der Kaltwasseranschluß 3 bis zu seiner Austrittsstelle aus dem Innenraum 1ʹ des Gehäuses 1 eine Länge aufweist, die größer ist als die kleinste Distanz zwischen der Wand des Speicherbehälters 2 und das diesen umgebenden Gehäuses 1. Der als Wellrohr 5 ausgebildete Abschnitt 5ʹ des Kaltwasseranschlusses 3 bildet dabei den größeren Teil von dessen Länge innerhalb des wasserführenden Gehäuseinnenraumes 1ʹ, wobei der Kaltwasseranschluß 3 die Gehäusewand 1ʺ im Bereich einer in bezug auf seinen eigenen Durchmesser größeren Öffnung 6 durchgreift. Der aus der Öffnung 6 herausragende Teil des Kaltwasseranschlusses 3 erstreckt sich innerhalb einer haubenartigen Abdeckung 7 der Öffnung, d.h., der Innenraum dieser Abdeckung 7 gehört ebenfalls mit zum Innenraum 1ʹ des Gehäuses 1. Der Durchgriffsöffnungsrand 8 der Abdeckung 7 ist mit dem Leitungsanschlußendbereich 9 des Kaltwasseranschlusses 3 flüssigkeitsdicht verbunden.The domestic hot water tank consists of a
Wie ferner aus Fig. 1 ersichtlich, ist der Boden 4 des Speicherbehälters 2 im Bereich der Einmündung des Kaltwasseranschlusses 3 in den Boden 4 des Speicherbehälters mit einer Einbuchtung 10 versehen, die eine zur Längsachse 11 des Kaltwasseranschlusses 3 senkrechte oder angenähert senkrechte Einmündungswand 12 aufweise, was die Einbindung des wellenfreien Endes des Kaltwasseranschlusses in den Boden 4 erleichtert. Das speicherbodenseitige und wellenfreie Ende 13 des Kaltwasseranschlusses 3 ist dabei mit einem sich in Längsrichtung des Anschlusses erstreckenden Stützsteg 14 gegen die obere Begrenzungswand 15 der Einbuchtung 10 abgestützt. Dadurch wird jede Belastung der Ringschweißnaht für die Einbindung des wellenfreien Endes 13 vermieden. Die haubenartige und relativ lange Abdeckung 7 der im Querschnitt runden oder ovalen Durchgriffsöffnung 6 ist in Form eines Rohrstückes 7ʹ ausgebildet und in geeigneter Weise flüssigkeitsdicht mit dem Umfangsrand der Durchgriffsöffnung 6 verbunden bzw. mit einem besonderen Blechring, an dem ein Anschlußflansch ausgebildet ist, der aber hier keine Rolle spielt. Dieser Blechring, wenn vorhanden und wie dargestellt, muß dann natürlich eine entsprechende, zur Durchgriffsöffnung 6 fluchtende Öffnung aufweisen. Die diesbezüglich mit dargestellte besondere Gestaltung des wasserführenden Gehäuses 1 ist ebenfalls unwesentlich, d.h., das wasserführende Gehäuse 1 kann unter dem Boden 4 des Speicherbehälters auch ein abgeschlossenes Gehäuse bilden, das dann nicht, wie dargestellt, in offener Verbindung zu einem unter dem Gehäuse 1 befindlichen Gehäuse eines Feuerungsteiles steht. Das Rohrstück 7ʹ hat eine Länge, die vorteilhaft mindestens einem Drittel der Länge des sich im wasserführenden Innenraum 1ʹ von Gehäuse 1 und Rohrstück 7ʹ erstreckenden Kaltwasseranschusses 3 entspricht.1, the bottom 4 of the
Aufgrund der unterbringbaren relativ großen Länge des Kaltwasseranschlusses 3 kann auch der Abschnitt 5ʹ des Wellrohres entsprechend lang gehalten werden, wodurch man nicht gezwungen ist, diesen mehr oder weniger elastischen Teil des Kaltwasseranschlusses mit sehr engen und dicht gefalteten Wellungen zu versehen. Vorteilhaft und bevorzugt sind deshalb die Wellen 17 des Wellrohres 5, wie in Fig. 2 dargestellt, mit einer Tiefe T angelegt, die kleiner ist als die Wellenlänge L.Because of the relatively large length of the
Wie gestrichelt in Fig. 1 angedeutet, kann die Unterbringung eines relativ langen, mit entsprechend langem elastischen Wellrohrabschnittes auch dadurch erreicht werden, daß die Einmündungsstelle 16 des behälterseitigen Endes 13 des Kaltwasseranschlusses 3 gegenüberliegent bzw. relativ weit entfernt von der Durchgriffsstelle an der Behälterwand angeordnet ist, d.h., in diesem Falle erstreckt sich der größere Teil des Kaltwasseranschlusses 3 unterhalb des Bodens 4 des Speicherbehälters. In Rücksicht auf die in dieser Weise unterbringbare große Länge kann dann das Leitungsanschlußende 9 wieder direkt mit dem Rand der dann entsprechend kleiner gehaltenen Durchgriffsöffnung 6 flüssigkeitsdicht verbunden werden. Die Anordnung einer haubenartigen Abdeckung 7, wie vorbeschrieben, kann dann entfallen. Stützstege 14 können im übrigen sowohl bei dieser Ausführungsform als auch bei der vorbeschriebenen Ausführungsform auch am leitungsanschlußseitigen Ende 9 des Kaltwasseranschlusses 3 vorgesehen werden, d.h., entweder innerhalb der Abdeckung 7 oder im zweiten Fall an der Behälterwand.As indicated by dashed lines in Fig. 1, the accommodation of a relatively long, with a correspondingly long elastic corrugated tube section can also be achieved in that the
