Description
Die Erfindung bezieht sich auf ein metallisches Entleerungsrohr für einen elektrischen Heißwasserbereiter unter Verwendung von Kunststoff, Porzellan, Lack od. dgl. als Schutz gegen Kesselsteinansatz.The invention relates to a metallic discharge pipe for an electric water heater using plastic, porcelain, Paint or the like as protection against scale build-up.
Bei Heißwasserbereitern zeigt sich immer wieder der Nachteil, daß sich im Ausströmrohr, beispielsweise im überlaufrohr eines elektrischen Heißwasserbereiters, verhältnismäßig leicht Kalk ansetzt. Vor allem im oberen Teil von überlaufrohren bilden sich Kalkablagerungen, welche dazu führen, daß das Rohr sich ganz oder zumindest teilweise zusetzt. Dadurch können unangenehme Schwierigkeiten entstehen, z. B. kann bei überlaufspeichern eine Explosionsgefahr für den Speicher hervorgerufen werden.The disadvantage of hot water heaters is that in the outlet pipe, for example in the overflow pipe of an electric water heater, lime builds up relatively easily. Especially in the upper part of overflow pipes Lime deposits form, which lead to the fact that the pipe is completely or at least partially clogs. This can cause uncomfortable difficulties, e.g. B. can in the case of overflow storage tanks, there is a risk of explosion for the storage tank.
Es ist deshalb schon vorgeschlagen worden, die mit dem Wasser in Berührung kommenden Teile von Heißwasserbereitern aus kesselsteinabweisendem Kunststoff zu fertigen oder mit einem entsprechenden Überzug zu versehen. Diese Aufbauform ist jedoch sehr teuer und schwierig herzustellen, weil sich die mit Kunststoff überzogenen Teile nicht in herkömmlicher Weise verarbeiten lassen.It has therefore already been suggested that those in contact with the water coming parts of water heaters made of scale-resistant plastic finished or provided with an appropriate coating. This design is however, very expensive and difficult to manufacture because they are coated with plastic Do not process parts in the conventional way.
Um diese Nachteile zu vermeiden, ist gemäß der Erfindung vorgesehen, das Entleerungsrohr mit einer mindestens teilweise aus Kunststoff, Porzellan, Lack od. dgl. erstellten Tülle zu versehen.In order to avoid these disadvantages, it is provided according to the invention, the emptying pipe with an at least partially made of plastic, porcelain, lacquer or the like. Created grommet to be provided.
Es ist durch die Erfindung ohne weiteres möglich, das Entleerungsrohr in den Behälter z. B. durch Löten oder Schweißen einzusetzen und abschließend mit der Tülle zu versehen.It is easily possible through the invention to remove the drainage pipe in the container z. B. to be used by soldering or welding and finally with to provide the grommet.
Im Bedarfsfalle kann die kesselsteinabweisende Tülle auf denkbar einfachste Weise ausgewechselt werden.If necessary, the scale-repellent grommet can be used in the simplest possible way Way to be exchanged.
An Hand der Zeichnung seien Ausführungsbeispiele der Erfindung dargestellt und näher beschrieben.Exemplary embodiments of the invention are shown with reference to the drawing and described in more detail.
Die F i g. 1 zeigt in schematischer Darstellung den Flüssigkeitsbehälter 1 eines Heißwasserspeichers, der von einer Isolationsschicht 2 umgeben und nach unten durch die Flanschplatte 3 abgeschlossen ist. Diese Flanschplatte 2 trägt unter anderem das Zulaufrohr 4 und das Entleerungsrohr 5 (Ausströmrohr).The F i g. 1 shows the liquid container in a schematic representation 1 of a hot water tank, which is surrounded by an insulation layer 2 and after is completed at the bottom by the flange plate 3. This flange plate 2 carries under among other things, the inlet pipe 4 and the discharge pipe 5 (outflow pipe).
Um die durch Kalkablagerung im Entleerungsrohr entstehenden Schwierigkeiten zu vermeiden, ist, wie in F i g. 2 näher dargestellt, der obere Teil des Entleerungsrohres 5 mit einer Tülle 6 versehen, die entweder aus einem kesselsteinabweisenden Material besteht oder wenigstens einen Überzug aus einem solchen Material besitzt. Ein derartiger Überzug kann z. B. aus einem geeigneten Lack erstellt werden.To avoid the difficulties caused by limescale deposits in the emptying pipe is to be avoided, as shown in FIG. 2 shown in more detail, the upper part of the emptying pipe 5 provided with a grommet 6, either made of a scale-repellent material consists or at least has a coating of such a material. One of those Coating can e.g. B. can be created from a suitable paint.
