Description

Die Erfindung betrifft einen Doppelmantelspeicher für die Bereitung und Speicherung von warmem Brauchwasser, bestehend aus einem mit Kaltwasserzufuhr- und Warmwasserablaufanschluß versehenem Behälter, der mit einem formangepaßten, das Heizmedium führenden Außenmantel umgeben ist, an dem Heizmediumsvor- und Rücklaufanschlüsse angeordnet sind.The invention relates to a double jacket storage for the preparation and storage of hot service water, consisting of a container provided with cold water supply and hot water outlet connection, which is surrounded by a shape-matching outer jacket guiding the heating medium, on which heating medium supply and return connections are arranged.

Derartige Doppelmantelspeicher sind hinlänglich bekannt und in Benutzung, so daß es diesbezüglich keines besonderen druckschriftlichen Nachweises bedarf. Der eigentliche Speicherbehälter sitzt dabei im formangepaßten, topfförmigen Außenmantel und ragt mit einem Ende, d.h. mit seinem dort befindlichen Boden aus dem Außenmantel heraus, oder der dann nur zylindrisch ausgebildete Außenmantel umfaßt im wesentlichen nur den zylindrischen Teil des Behälters. Um den Spalt zwischen Außenmantel und Speicherbehälter abzuschließen, wird in der Regel ein am Außenumfang abgekröpfter Abschlußring eingeschweißt, der also separat hergestellt werden muß und für dessen Verbindung mit dem Behälter und dem Anschlußrand des Außenmantels es zweier umlaufender Schweißnähte bedarf. Eine insoweit besser Lösung stellt ein Speicherbehälter nach dem DE-U-91 13 120 dar, bei dem der Abschlußring in Form einer Abkröpfung des Umfangsrandes des Behälterbodens ausgebildet ist, an die die Endränder der Seitenwandteile des Innen- und des Außenbehälters flüssigkeitsdicht angeschlossen sind. Dies verlangt eine entsprechende Bemessungszugabe am Bodenblechzuschnitt, um beim Ausformen des Bodens den Abschlußringbereich mit ausformen zu können. Außerdem sind besondere Formgebungsmaßnahmen erforderlich, um eine koaxiale Zuordnung vom Boden zum zylindrischen Teil des Behälters und vom Endrand des Außenmantels zum am Boden angeformten Abschlußring zu gewährleisten.Such double jacket storage are well known and in use, so that no special printed evidence is required in this regard. The actual storage container sits in the form-fitting, pot-shaped outer jacket and protrudes with one end, i.e. with its bottom located out of the outer jacket, or the then only cylindrical outer jacket essentially comprises only the cylindrical part of the container. In order to close off the gap between the outer casing and the storage container, an end ring bent off on the outer circumference is generally welded in, which must therefore be produced separately and requires two circumferential weld seams for its connection to the container and the connecting edge of the outer casing. A so far better solution is a storage container according to DE-U-91 13 120, in which the end ring is designed in the form of an offset of the peripheral edge of the container bottom, to which the end edges of the side wall parts of the inner and outer containers are connected in a liquid-tight manner. This requires a corresponding dimensioning allowance on the floor panel cut so that the end ring area can also be formed when the floor is being shaped. In addition, special shaping measures are required to ensure a coaxial assignment from the bottom to the cylindrical part of the container and from the end edge of the outer jacket to the end ring molded onto the bottom.

Der Erfindung liegt die Aufgabe zugrunde, einen Doppelmantelspeicher der gattungsgemäßen Art bezüglich seines Außenmantelabschlusses dahingehend zu verbessern und zu vereinfachen, daß es weder der Anfertigung und Einschweißung eines separaten Ringes noch einer besonderen Ausformung des Behälterabschlußbodens bedarf.The invention has for its object to improve and simplify a double jacket memory of the generic type with respect to its outer jacket termination in that it is neither the manufacture and welding of a separate Ring still requires a special shape of the container bottom.

Diese Aufgabe ist mit einem Doppelmantelspeicher der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Hauptanspruches angeführten Merkmale gelöst. Vorteilhafte Weiterbildungen und Ausgestaltungen ergeben sich nach den Unteransprüchen.This object is achieved with a double jacket memory of the type mentioned according to the invention by the features stated in the characterizing part of the main claim. Advantageous further developments and refinements result from the subclaims.

Die nach außen gewölbte Umlaufsicke ist dabei auf einfache Weise, und zwar ggf. schon beim Rollen des Blechzuschnittes zum zylindrischen Teil des Behälters mit herstellbar, wobei dann der Endrand des Außenmantels einfach an der Umlaufsicke angesetzt und verschweißt wird. Die Umlaufsicke wird dabei vorteilhaft zum benachbarten Boden des Behälters hin mit einer divergierenden Anlage- und Zentrierfläche versehen, an die der entsprechend divergierende Endrand des Außenmantels angelegt und verschweißt ist.The circumferential corrugation, which is curved outwards, can be produced in a simple manner, possibly even when the sheet metal blank is rolled into the cylindrical part of the container, the end edge of the outer casing then simply being attached to the circumferential corrugation and welded. The peripheral bead is advantageously provided with a diverging contact and centering surface towards the adjacent bottom of the container, to which the correspondingly diverging end edge of the outer jacket is applied and welded.

Um in Rücksicht auf die abzudeckende Spaltbreite zwischen Behälter und Außenmantel die Umlaufsicke nicht entsprechend tief einrollen zu müssen, kann der divergierende Endrand des Außenmantels als Verlängerung einer zum betreffenden Boden hin konvergierend orientierten Umlaufkröpfung ausgebildet werden, was noch näher erläutert wird.In order not to have to roll the surrounding bead deep enough in view of the gap width to be covered between the container and the outer casing, the diverging end edge of the outer casing can be designed as an extension of a circulating cranking oriented towards the floor in question, which will be explained in more detail below.

Sofern es sich um einen Speicherbehälter mit einem Außenmantel handelt, der nur den zylindrischen Teil des Behälters umfaßt, ist vorgesehen, daß der Außenmantel am anderen Ende mit einem gegen den Behälter hin eingekröpften Verschlußrand, dieser mit einem zur Behälterachse achsparallel erstreckten, zum benachbarten Boden hin gerichteten Anlagerand versehen und mit diesem am Behälter verschweißt ist. Denk- und machbar wäre aber auch, das Prinzip der Anordnung einer Umlaufsicke an diesem Ende vorzusehen, wobei allerdings diese Umlaufsicke bzgl. ihrer Auswölbung etwas geringer bemessen werden muß, um den Endrand des Außenmantels, der für den Anschluß an der anderen Umlaufsicke bestimmt ist, über die geringer ausgewölbte Umlaufsicke schieben zu können.If it is a storage container with an outer casing that only comprises the cylindrical part of the container, it is provided that the outer casing at the other end with a locking edge that is crimped against the container, this with an axis parallel to the container axis, towards the adjacent floor Provide directed investment edge and is welded to the container with this. It would also be conceivable and feasible to provide the principle of arranging a peripheral bead at this end, although this peripheral bead must be dimensioned somewhat less in terms of its bulge around the end edge of the outer jacket, which determines the connection to the other peripheral bead is to be able to slide over the less convex bead.

Der erfindungsgemäße Doppelmantelspeicher wird nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The double jacket memory according to the invention is explained in more detail below with reference to the drawing of exemplary embodiments.

Der Doppelmantelspeicher besteht aus einem mit Kaltwasserzufuhr- und Warmwasserablaufanschluß 3, 4 versehenem Behälter 1, der mit einem formangepaßten, das Heizmedium führenden Außenmantel 2 umgeben ist, an dem Heizmediumsvor- und -rücklaufanschlüsse 6, 7 angeordnet sind.The double jacket storage consists of a cold water supply and hot water outlet connection 3, 4 provided container 1, which is surrounded by a shape-matching, the heating medium leading outer jacket 2, are arranged on the heating medium supply and return connections 6, 7.

Dargestellt ist in Fig. 1 ein Vertikalspeicher, wobei der Außenmantel 2 topfförmig ausgebildet ist und den Behälter 1 bis auf das Oberteil umschließt, und in Fig. 4 ein Horizontalspeicher, bei dem nur der im wesentlichen zylindrische Teil 1' des Behälters 1 vom Außenmantel 2' umfaßt ist.1 shows a vertical store, the outer casing 2 being cup-shaped and enclosing the container 1 except for the upper part, and in FIG. 4 a horizontal store in which only the essentially cylindrical part 1 'of the container 1 from the outer casing 2 'is included.

Für beide Speicherarten ist nun, was den Abschluß des Außenmantels 2, 2' nach einer Seite hin betrifft, wesentlich, daß der Speicherbehälter 1 im Bereich des Endes 8 des Außenmantels 2 mit einer nach außen gewölbten Umlaufsicke 9 versehen und an dieser Umlaufsicke 9 der Endrand 10 des Außenmantels 2 angeschweißt ist. Hierzu wird insbesondere auf Fig. 2 verwiesen, die insoweit keiner weiteren Erläuterung bedarf.For both types of storage, it is now essential that the end of the outer casing 2, 2 'on one side is that the storage container 1 is provided in the region of the end 8 of the outer casing 2 with an outwardly curved peripheral bead 9 and the end edge 10 of the outer jacket 2 is welded to this peripheral bead 9. In this regard, reference is made in particular to FIG. 2, which does not require any further explanation in this respect.

Bevorzugt wird die Ausführungsform gemäß Fig. 3, bei der die Umlaufsicke 9 zum benachbarten Boden 11 des Behälters 1 hin mit einer divergierenden Anlage- und Zentrierfläche 12 versehen und an dieser der entsprechend divergierende Endrand 10 des Außenmantels 2 angelegt und verschweißt ist. Wie ohne weiteres aus Fig. 3 erkennbar, erhält dabei der Außenmantel 2 beim Zusammenfügen automatisch eine achsparallele Zentrierung zum Behälter 1.The embodiment according to FIG. 3 is preferred, in which the peripheral bead 9 is provided with a diverging contact and centering surface 12 towards the adjacent bottom 11 of the container 1 and the correspondingly diverging end edge 10 of the outer jacket 2 is applied and welded thereon. As can readily be seen from FIG. 3, the outer casing 2 automatically receives an axially parallel centering to the container 1 when it is joined together.

Beim in Fig. 3 dargestellten Ausführungsbeispiel ist ferner der divergierende Endrand 10 des Außenmantels 2 als Verlängerung einer zum betreffenden Boden 11 hin konvergierend orientierten Umlaufkröpfung 13 ausgebildet. Abgesehen davon, daß eine solche Umlaufkröpfung 13 denkbar einfach und in Verbindung mit dem divergierenden Endrand 10 herzustellen ist, hat diese Ausgestaltung den Vorteil, daß die Umlaufsicke 9 weniger tief nach außen ausgewölbt werden muß.In the exemplary embodiment shown in FIG. 3, the diverging end edge 10 of the outer casing 2 is also designed as an extension of a circumferential crank 13 oriented converging towards the relevant floor 11. In addition to the fact that such a circumferential crank 13 is very simple to produce and in connection with the diverging end edge 10, this embodiment has the advantage that the circumferential bead 9 does not have to be bulged out so deeply.

Beim Horizontalspeicher gemäß Fig. 4 ist der Außenmantel 2', der hier nur den zylindrischen Teil 1' des Behälters 1 umfaßt, in gleicher Weise, wie zu Fig. 3 erläutert, am Behälter 1 bzw. an dessen Umlaufsicke 9 auf der linken Seite angeschlossen. Auf der anderen Seite bzw. am anderen Ende 8' ist der Außenmantel 2' (siehe Fig. 5) mit einem gegen den Behälter 1 hin eingekröpften Verschlußrand 14 versehen, der einen zur Behälterachse 15 achsparallel erstreckten, zum benachbarten Boden 11' hin gerichteten Anlagerand 15 aufweist und mit diesem am Behälter 1 verschweißt ist.4, the outer casing 2 ', which here only comprises the cylindrical part 1' of the container 1, is connected in the same way as explained in connection with FIG. 3 to the container 1 or to its peripheral bead 9 on the left side . On the other side or at the other end 8 ', the outer jacket 2' (see FIG. 5) is provided with a locking edge 14 which is cranked towards the container 1 and which has an abutment edge which extends axially parallel to the container axis 15 and is directed towards the adjacent bottom 11 ' 15 and is welded to the container 1.

Wie vorerwähnt, könnte aber auch dieser Abschlußbereich in gleicher Weise, wie in Fig. 3 dargestellt, ausgebildet werden, dies aber dann mit der Maßgabe, daß dort die Umlaufsicke 9 nur so weit ausgewölbt sein darf, daß der Endrand 10 darüber hinweggeschoben werden kann. Der Verschlußrand 14 kann dann weniger breit bemessen werden, und der Anlagerand 16 ist dann in seiner Orientierung ebenfalls an die dortige Anlage- und Zentrierfläche der Umlaufsicke angepaßt.As mentioned above, this termination area could also be designed in the same way as shown in FIG. 3, but with the proviso that the peripheral bead 9 there only may be bulged out so far that the end edge 10 can be pushed over it. The closure edge 14 can then be dimensioned to be less wide, and the bearing edge 16 is then also adapted in its orientation to the contact and centering surface there of the peripheral bead.
