Description
Die Erfindung betrifft einen Wasserbehälter, insbesondere für einen Warmwasserbereiter, mit einem Innenbehälter aus Kunststoff und einer armierenden Glasfaserbewicklung, die gegebenenfalls von einer Schaumstoffschicht umhüllt istThe invention relates to a water tank, in particular for a water heater, with a Inner container made of plastic and a reinforcing glass fiber wrapping, which may be covered by a Foam layer is wrapped
Ein derartiger Wasserbehälter ist aus dem DE-Gm 74 12 817 bekannt Bei solchen Wasserbehältern ist der Innenbehälter (Liner) im Blasverfahren hergestellt und als solcher nicht geeignet, größere Wasserdrücke aufzunehmen. Es ist deshalb der Innenbehälter mit kunststoffgetränkten Glasfäden (Rovings) bewickelt Hierdurch tritt allerdings eine unerwünschte Geruchsbildung des Brauchwassers auf, die durch Diffusion des die Glasfäden tränkenden Kunststoffes in dem Innenbehälter entsteht Darüber hinaus ist die vollständige Tränkung der Glasfaserbewicklung mit Kunststoffmasse teuer. Aus dem DE-Gm 7412817 ist es weiter bekannt, in den praktisch nicht zu bewickelnden Kuppenbereicher des Innenbehälters Versteifungskappen vorzusehen.Such a water tank is known from DE-Gm 74 12 817. In such water tanks is the Inner container (liner) manufactured in a blow molding process and as such not suitable for higher water pressures to record. The inner container is therefore wrapped with plastic-soaked glass threads (rovings) However, this results in an undesirable odor formation in the process water, which is caused by diffusion of the In addition, the glass threads soaking plastic in the inner container is complete Impregnation of the fiberglass wrapping with plastic compound is expensive. From DE-Gm 7412817 it is further known, stiffening caps in the tip area of the inner container, which is practically not to be wrapped to be provided.
In der DE-OS 14 54 723 ist ein thermischer Isolationskörper aus einer Schaumstoffschicht für elektrische Heißwasserspeicher beschrieben. In den Isolationskörper ist zu seiner Versteifung eine Glasfasermatte oder ein ähnlicher Körper eingeschäumt Der versteifte Isolationskörper liegt dabei am Innenbehälter an. Die Probleme, mit deren Lösurg sich die Erfindung befaßt, entstehen hier nicht Ein im Blasverfahren hergestellter Innenbehälter läßt sich mit dem versteiften Isolationskörper nicht ausreichend armieren. Insbesondere soll mit dem Vorschlag der DE-OS 14 54 723 der Innenbehälter gegen die beim Betrieb eines elektrischen Heißwasserbereiters auftretenden Unterdrücke stabil gemacht werden.In DE-OS 14 54 723 a thermal insulation body made of a foam layer for electrical Hot water storage tank described. In the insulation body is a fiberglass mat or to stiffen it a similar body foamed in. The stiffened insulation body rests against the inner container. the Problems with the solution of which the invention is concerned do not arise here The inner container cannot be adequately reinforced with the stiffened insulation body. In particular, should with the proposal of DE-OS 14 54 723 the inner container against the operation of an electric The negative pressures occurring in the hot water heater can be made stable.
Aufgabe der Erfindung ist es, einen Wasserbehälter eingangs genannter Art vorzuschlagen, bei dem eine Geruchsannahme des Brauchwassers vermieden wird.The object of the invention is to propose a water tank of the type mentioned, in which a Odor absorption of the domestic water is avoided.
Nach der Erfindung wird obige Aufgabe dadurch gelöst, dad die Glasfaserbewicklung nur an Einzelstellen durch Kunststoffmasse mit dem Innerbehälter verbunden oder ohne verbindende Kunststoffmasse zwischen der Schaumstoffschicht und dem Innenbehälter angeordnet istAccording to the invention, the above object is achieved in that the glass fiber wrapping is only carried out at individual points connected by plastic compound to the inner container or without a connecting plastic compound between the foam layer and the inner container is arranged
Durch die nur stellenweise Kunststofftränkung der Glasfasern ist die eingesetzte Kunststoff-Tränkmenge wesentlich reduziert Dadurch ist vermieden, daß das Brauchwasser einen Geruch annimmt Gleichzeitig erniedrigen sich die Herstellungskosten, da nur noch wenig Kunststoffmasse eingesetzt werden muß.The plastic impregnation amount used is due to the plastic impregnation of the glass fibers only in places significantly reduced This prevents the process water from taking on an odor at the same time the manufacturing costs are reduced, since only a small amount of plastic compound has to be used.
Die um die Glasfaserbewicklung geschäumte Schaumstoffschicht, die insbesondere ein Polyurethan-Mantel ist, bildet einen Schutz und einen sicheren Halt der Glasfaserbewicklung an dem Innenbehälter. In bestimmten Anwendungsfällen genügt auch die um die Glasfaserbewicklung geschäumte Schaumstoffschicht allein zur Fixierung der Glasfaserbewicklung.The foam layer foamed around the glass fiber wrapping, in particular a polyurethane jacket forms a protection and a secure hold of the fiberglass wrapping on the inner container. In For certain applications, the foam layer foamed around the glass fiber wrapping is also sufficient solely for fixing the fiberglass wrapping.
Um einer Verrottung der Glasfasern vorzubeugen, kann der Innenbehälter mit einem dampfdichtenIn order to prevent the glass fibers from rotting, the inner container can be vapor-proofed
Die Erfindung wird anhand eines Ausführungsbeispiels
näher erläutert Die Figur zeigt einen erfindungsgemäßen Wasserbehälter teilweise geschnitten.
Ein Kunststoff-Innenbehälter 1 trägt an seinen sphärisch gewölbten Enden Versteifungskappen 2 und 3.
Diese sind von Aluminium-Formteilen gebildet Sie weisen Ansätze 4 und 5 auf, mittels denen der
Innenbehälter in eine Wickelmaschine einspannbar ist Durch den Ansatz 5 sind die Anschlußelemente, wieThe invention is explained in more detail using an exemplary embodiment. The figure shows a water tank according to the invention, partially in section.
A plastic inner container 1 has stiffening caps 2 and 3 at its spherically curved ends. These are formed from aluminum moldings
Der Innenbehälter 1 mit den Versteifungskappen 2 und 3 ist mit Glasfasern 6 bewickelt Die Glasfaserbewicklung 6 überlappt die Versteifungskappen 2 und 3. Die Glasfasern sind nur an wenigen Stellen mitThe inner container 1 with the stiffening caps 2 and 3 is wound with glass fibers 6. The glass fiber winding 6 overlaps the stiffening caps 2 and 3. The glass fibers are only in a few places
Kunststoffmasse getränkt, beispielsweise an den Stellen 7 und 8 der Versteifungskappen und an einer Stelle 9. Dabei liegen an der Stelle 9 die Glasfaserenden einer Bewicklung des zwischen den Versteifungskappen 2 und 3 liegenden Teils des Innenbehälters. An den Stellen 7 und 8 liegen die Enden einer zusätzlichen, mit der erstgenannten Bewicklung verzopften Kreuzbewicklung des Innenbehälters und der Versteifungskappen.Soaked plastic mass, for example at the points 7 and 8 of the stiffening caps and at a point 9. Here, the glass fiber ends are at the point 9 Wrapping of the part of the inner container lying between the stiffening caps 2 and 3. At positions 7 and 8 are the ends of an additional cross-winding twisted with the first-mentioned winding the inner container and the stiffening caps.
Der bewickelte Innenbehälter 1 ist in einen Außenmantel 10 eingesetzt Der Freiraum zwischenThe wound inner container 1 is inserted into an outer jacket 10. The space between

Im Rahmen der Erfindung ist es möglich, die Einzelstellen, an denen die Glasfaserbewicklung mit Kunststoffmasse getränkt ist in je nach der Bewicklungsart geeignete Bereiche zu legen. Liegen dieIn the context of the invention, it is possible to identify the individual points where the fiberglass wrapping with Soaked with plastic material, it is to be placed in suitable areas depending on the type of winding. Are the
