DurchlauferhitzerWater heater

Die Erfindung bezieht sich auf einen Durchlauferhitzer mit einem das zu beheizende Medium, z.B. Wasser führenden Rohr, an dem ein Heizrohr entlanggeführt ist.The invention relates to a flow heater with a pipe carrying the medium to be heated, e.g. water, on which a Heating pipe is guided along.

Derartige Durchlauferhitzer finden beispielsweise bei elektrischen Kaffeemaschinen Verwendung, wobei das als elektrischer .Rohrheizkörper ausgebildete Heizrohr entweder neben dem wasserführenden Rohr in einen wärmeleitenden Träger eingelegt oder mit dem wasserführenden Rohr verlötet ist. Beide Ausführungsformen erfordern einen verhältnismäßig großen Fertigungsaufwand. Außerdem ist der Wärmeübergang vom Heizrohr zum wasserführenden Rohr in vielen Pällen unbefriedigend. . -Such water heaters can be found, for example, in electric Coffee machines use, with that as an electric .pipe heater trained heating pipe either inserted next to the water-carrying pipe in a heat-conducting carrier or with the water-carrying pipe Pipe is soldered. Both embodiments require a relatively large manufacturing effort. Besides, the Heat transfer from the heating pipe to the water-carrying pipe in many areas unsatisfactory. . -

Aufgabe der Erfindung ist es, die Herstellung eines Durchlauferhitzers der eingangs beschriebenen Art zu vereinfachen und bei einem derartigen Element einen genau definierten Wärmeübergang vom Heizrohr zum wasserführenden Rohr zu schaffen.The object of the invention is to produce a flow heater of the type described at the outset and, in the case of such an element, a precisely defined heat transfer to create from the heating pipe to the water pipe.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die beiden Rohre als ein einstückiges Strangprofil ausgebildet sind. Dabei können nach verschiedenen Ausführungsformen der Erfindung die beiden Rohre durch einen Steg miteinander in Verbindung stehen oder gemeinsame Wandteile aufweisen.According to the invention, this object is achieved in that the two tubes are designed as a one-piece extruded profile. According to various embodiments of the invention, the two tubes can be connected to one another by a web or have common wall parts.

Es ist im Rahmen der Erfindung auch möglich, daß eines der beiden Rohre, vorzugsweise das Heizrohr^ in die Wandung des anderen Rohres eingeformt ist oder daß eines der beiden Rohre von dem anderen Rohr mit Abstand umschlossen ist, Bei der letztgenannten Ausfüh- ( rungsform sind die beiden Rohre durch Radialstege miteinander verbunden. It is also possible within the scope of the invention that one of the two tubes, preferably, the heater tube ^ is formed in the wall of the other pipe, or that one of both tubes is enclosed by the other tube at a distance, In the latter execution (approximate shape are the two tubes are connected to one another by radial webs.

Entsprechend den Erfordernissen der Praxis können die beiden Rohre verschiedenen Querschnitt aufweisen, wobei dieeer Querschnitt, von der Kreisform abweichen kann. Das Heizrohr ist in einer bevorzugten Ausführungsform als elektrischer Rohrheizkörper ausgebildet. In diesem Fall ist der lichte Querschnitt des den Mantel des Rohrheizkörpers bildenden Heizrohres nach dem Einbringen des Heizleiters und der diesen umgebenden Isoliermasse in an sich bekannter Weise zu verringern.According to the requirements of practice, the two tubes have different cross-sections, theeer cross-section, of the circular shape can deviate. The heating tube is in a preferred one Embodiment designed as an electric tubular heater. In this case, the clear cross-section is the jacket of the tubular heater forming heating tube after the introduction of the heating conductor and the insulating compound surrounding it in a known manner Way to decrease.

In der Zeichnung sind Ausführungsbeispiele erfindungsgemäß ausgebildeter Strangprofile im Querschnitt dargestellt.In the drawing, exemplary embodiments are designed according to the invention Extruded profiles shown in cross section.

Das in Pig. 1 gezeigte einstückige Strangprofil besteht aus einem das zu beheizende Medium» insbesondere Wasser führenden Rohr 1 und einem Heizrohr 2, Beide Rohre weisen den gleichen Querschnitt auf und sind durch einen gemeinsamen Wandteil 3 miteinander verbunden. ; That in Pig. The one-piece extruded profile shown in FIG. 1 consists of a pipe 1 carrying the medium to be heated, in particular water, and a heating pipe 2. Both pipes have the same cross section and are connected to one another by a common wall part 3. ;

Das Ausführungsbeispiel nach Pig. 2 weist zwei Rohre 1, 2 mit unterschiedlichem Querschnitt auf, die durch einen Steg 4 miteinander in Verbindung stehen. The embodiment according to Pig. 2 has two tubes 1, 2 with different cross-sections, which are connected to one another by a web 4.

In dem Ausführungsbeispiel nach Pig. 3 weisen die beiden durch einen gemeinsamen Wandteil 3 miteinander in Verbindung stehenden Rohre 1,2 sechseckigen Querschnitt auf.In the embodiment according to Pig. 3 show the two that are connected to one another by a common wall part 3 Tubes 1.2 hexagonal cross-section.

In Pig. 4 ist das runde Rohr 1 über einen Steg 4 mit einem ebenfalls sechseckig ausgebildeten Rohr 2 verbunden.In Pig. 4 is the round tube 1 via a web 4 with a likewise hexagonal tube 2 connected.

In dem Ausführungsbeispiel nach Pig. 5 ist das Heizrohr 2 in die Wandung des wasserführenden Rohres 1 eingeformt.In the embodiment according to Pig. 5, the heating pipe 2 is molded into the wall of the water-carrying pipe 1.

Bei der in Pig. 6 dargestellten Ausführungsform umgibt das was-BerführendeRohr 1 das Heizrohr 2 mit Abstandt wobei die Rohre 1 und 2 durch Radialstege 5 miteinander starr verbunden sind.In Pig. In the embodiment shown in FIG. 6, the what-carrying pipe 1 surrounds the heating pipe 2 at a distance t , the pipes 1 and 2 being rigidly connected to one another by radial webs 5.
