Description
Elektrischer DurchlauferhitzerElectric water heater
D^e Neuerung "betrifft einen elektrischen Durchlauferhitzer zum Erwärmen flüssiger Medien, wie er insbesondere auch zum Einbau in Kaffeemaschinen verwendet wird.The innovation "concerns an electric water heater for heating liquid media, as it is also used in particular for installation in coffee machines.
Derartige Durchlauferhitzer bestehen im wesentlichen aus dem Durchlaufrohr für das zu erwärmende Medium und einem oder mehreren mit diesem verbundenen, parallel laufenden Hohrheizkörpern.Such water heaters essentially consist of the flow pipe for the medium to be heated and a or several with this connected, parallel running high heaters.
Vielfach besteht dieser Aufbau aus einem Stranggußteil aus Aluminium o. dgl., das den Durchlaufkanal enthält und mit Nuten versehen ist, in die die Rohrheizkörper eingepreßt sind.In many cases, this structure consists of a continuously cast part made of aluminum or the like, which contains the flow channel and is provided with grooves into which the tubular heating elements are pressed.
Solche Durchlauferhitzer sind mehr oder weniger anfällig für Verkalkungen des Durchlaufrohres, was man in erster Linie durch möglichst geringe thermische Oberflächenbelastung zu vermeiden sucht.Such water heaters are more or less prone to limescale build-up in the flow pipe, which is what happens in the first place Seeks to avoid line by minimizing the thermal load on the surface.
Ein weiterer Nachteil der Verkalkung ist in der Gefahr der sogenannten Lochfraß-Korrosion zu sehen, die zu Undichtheiten im Durchlaufkanal führt.Another disadvantage of calcification is the danger the so-called pitting corrosion, which leads to leaks in the flow channel.
Zweck dieser Neuerung ist es, diese Probleme weitgehend zu beseitigen und einen Durchlauferhitzer zu schaffen, bei dem Verkalkung auf ein Minimum reduziert ist und damit a^ch deren schädlichen Polgen. Zu üesem Zweck ist gemäß der vorliegenden Neuerung die Innenwand des Durchleufrohras mit einer tpmperaturbeständigen Kunststoffschicht überzogen.The purpose of this innovation is to largely eliminate these problems and to create a water heater at the calcification is reduced to a minimum and thus a ^ ch their harmful poles. For this purpose, according to this Innovation the inner wall of the pass-through pipe with a Temperature-resistant plastic layer coated.

Diese neuerungsgemaße Ausgestaltung des Durchlauferhitzers verringert weitgehend die Kalkablagerung im Durchlaufkanal, verhindert darüber hinaus die Lochfraß-Korrosion und es hat sich überraschenderweise gezeigt, daß dio bei Kaffeemaschinen wichtige Brühtemperatur um einen nicht unwesentliehen Betrag erhöht wird.This innovation according to the design of the flow heater largely reduces the lime deposits in the flow channel, also prevents pitting corrosion and it has surprisingly been found that dio in coffee machines important brewing temperature is increased by a not insignificant amount.
Der Gegenstand der Neuerung ist in einem Ausführungsbeispiel erläutert.The subject of the innovation is explained in an exemplary embodiment.

Figure 2 shows the water heater according to Figure 1 in cross section.
Der Durchlauferhitzer besteht aus einem Stranggußteil 1 aus Aluminium o. dgl., das ein Durchiaufrohr 2 für das zu erwärmende Medium enthält, sowie zwei einander gegenüberliegende Längsnuten 5, in denen je ein elektrischer Rohrheizkörper 3 eingepreßt ist. Das Durchlaufrohr 2 ist beiderseits mit je einem Schlauchstutzen 6 versehen, der in das Durchlaufrohr 2 eingepreßt ist und so mit Letzterem den Durchiaufkanal bildet. The water heater consists of a continuously cast part 1 made of aluminum or the like contains heating medium, as well as two opposing longitudinal grooves 5, in each of which an electric tubular heater 3 is pressed in. The flow pipe 2 is on both sides with each provided with a hose connector 6, which is in the flow pipe 2 is pressed in and thus forms the flow channel with the latter.
Wenigstens das Durchlaufrohr 2 ist mit einer Innenbeschichtung 7 aus einem wärmebeständigen Kunststoff, beispielswei-*- se Tetraflourkohlenwasserstoff versehen, die die Metalloberfläche des Durchlaufrohrs 2 vollständig bedeckt. Diese Beschichtung 7 kann im Tauchverfahren, im Durchflußverfahren oder aber auch durch Innenbesprühen des Durchlaufrohres hergestellt werden. Anschließend wird der auf diese Art und Weise aufgebrachte Überzug durch Erhitzen eingebrannt.At least the flow pipe 2 is provided with an inner coating 7 made of a heat-resistant plastic, for example - * - se tetraflouric hydrocarbons that form the metal surface of the flow pipe 2 completely covered. This coating 7 can be used in the immersion process, in the flow-through process or can also be produced by spraying the inside of the flow tube. Then it is done this way applied coating is baked by heating.
Gegebenenfalls können auch die beiden Schlauchstutzen 6 in einem der genannten Verfahren innenbeschichtet werden j was beispielsweise in einem Arbeitsgang mit dem Innenbeschichteten des Durchlaufrohres 2 möglich wäre.If necessary, the two hose nozzles 6 can also be internally coated in one of the processes mentioned j what, for example, in one operation with the internal coating of the flow pipe 2 would be possible.
