BeschreibungDescription
Die Neuerung betrifft einen elektrischen Durchlauferhitzer für Haushaltsgeräte, wie Wasch- oder Geschirrspülmaschinen, bestehend aus einem von der zu erhitzenden Flüssigkeit durchströmten Rohrkörper und einem elektrischen Heizelement für den Rohrkörper, wobei der Rohrkörper nach außen hin von einem abschirmenden thermischen Isolierkörper umhüllt ist.The innovation concerns an electric instantaneous water heater for household appliances, such as washing machines or dishwashers, consisting of a tubular body through which the liquid to be heated flows and an electric heating element for the tubular body, whereby the tubular body is encased on the outside by a shielding thermal insulating body.
Ein Durchlauferhitzer dieser Art ist aus dem DE-GM 88 01 963 bekannt. Bei diesem Durchlauferhitzer ist um das von der zu erhitzenden Flüssigkeit durchströmte Metallrohr ein elektrischer Mantelrohrheizkörper schraubenförmig gewunden und an diesem gut wärmeleitend z.B. durch eine Lötverbindung befestigt. Für das beheizte Durchflußmetallrohr ist in diesem Fall aber ein Durchmesser von mindestens 40 mm erforderlich. Auch ist die Verlustwärme bei einem Durchlauferhitzer dieser Art noch verhältnismäßig groß.A continuous flow heater of this type is known from DE-GM 88 01 963. In this continuous flow heater, an electric jacketed pipe heater is wound in a screw shape around the metal pipe through which the liquid to be heated flows and is attached to it in a way that conducts heat well, e.g. by a soldered connection. In this case, however, a diameter of at least 40 mm is required for the heated flow metal pipe. The heat loss in a continuous flow heater of this type is also relatively high.
Der Neuerung liegt die Aufgabe zugrunde, einen Durchlauferhitzer der eingangs beschriebenen Art von kleiner, kompakter Form zu schaffen, dessen Verlustwärme vernachlässigbar gering ist.The innovation is based on the task of creating a continuous flow heater of the type described above with a small, compact form and whose heat loss is negligible.
Die Lösung dieser Aufgabe gemäß der Neuerung besteht darin, daß als Heizelement ein Heizleiter aus Widerstandsdraht dient und auf dem Rohrkörper ein verhältnismäßig dünner Isolierschichtträger für den Widerstandsdraht aufgebracht ist und der um den Isolierschichtträger gewickelte Widerstandsdraht durch eine überdeckende Keramik-oderThe solution to this problem according to the innovation consists in the fact that a heating conductor made of resistance wire serves as the heating element and a relatively thin insulating layer carrier for the resistance wire is applied to the tube body and the resistance wire wound around the insulating layer carrier is covered by a covering ceramic or

Zementschicht auf dem Isolierschichtträger festgelegt ist.Cement layer is fixed on the insulating layer carrier.
Vorteilhafte weitere Ausgestaltungen des Gegenstandes der Neuerung sind in den Unteransprüchen angegeben.Advantageous further embodiments of the subject matter of the innovation are specified in the subclaims.
Der Durchlauferhitzer nach der Neuerung zeichnet sich durch eine kleine und kompakte Einheit aus, die vor allem für einen Einbau in die Gehäuse von Wasch- oder Geschirrspülmaschinen bestens geeignet ist.The new instantaneous water heater is characterized by a small and compact unit, which is particularly suitable for installation in the housings of washing machines or dishwashers.
Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung dargestellt und wird anhand dieser nachfolgend näher beschrieben.An example of the innovation is shown in the drawing and is described in more detail below.
Es zeigen:Show it:
Fig. 1 einen rohrartigen Durchlauferhitzer im Längsschnitt undFig. 1 a tubular flow heater in longitudinal section and
Fig. 2 diesen Durchlauferhitzer in einer vergrößerten Querschnittsdarstellung.Fig. 2 shows this instantaneous water heater in an enlarged cross-sectional view.
Der Durchlauferhitzer nach der Zeichnung hat einen von der erhitzenden Flüssigkeit durchströmten Rohrkörper 1 aus Metall, der von einem Heizelement 2 beheizt wird. Das Heizelement 2 ist dabei ein Heizleiter aus Widerstandsdraht. Auf dem Rohrkörper 1 ist ein verhältnismäßig dünner Isolierschichtträger 3 aus keramischen Material oder dergl. vorzugsweise aufgeschmolzen. Um diesen Isolierschichtträger ist der Widerstandsdraht 2 straff gewickelt und ist durch eine überdeckende Keramik- oder Zementschicht 4 auf dem Isolierschichtträger 3 festgelegt. Auf den beiden unbeheizten Endstücken 5,6 des Rohrkörpers 1 sind die Heizeinheit 2,3,4 begrenzende Abschlußringe 7,7' aufgeschoben. Durch die Abschlußringe 7,7' sind zweckmäßig die elektrischen Anschlüsse 8,8' für das Heizelement 2 geführt. Am Wasserauslaufende (Endstück 5) des Durchfluß-Rohrkörpers 1 ist ein Sicherheitsthermostat 9 mit elektrischen Anschlüssen 10,10' zur Unterbrechung der Rohrkörper-Beheizung vorgesehen. Vorteilhaft ist es, den Sicherheitsthermostat zweipoligThe flow heater according to the drawing has a tubular body 1 made of metal through which the heated liquid flows and which is heated by a heating element 2. The heating element 2 is a heating conductor made of resistance wire. A relatively thin insulating layer carrier 3 made of ceramic material or the like is preferably melted onto the tubular body 1. The resistance wire 2 is tightly wound around this insulating layer carrier and is fixed to the insulating layer carrier 3 by a covering ceramic or cement layer 4. End rings 7,7' delimiting the heating unit 2,3,4 are pushed onto the two unheated end pieces 5,6 of the tubular body 1. The electrical connections 8,8' for the heating element 2 are expediently led through the end rings 7,7'. A safety thermostat 9 with electrical connections 10, 10' is provided at the water outlet (end piece 5) of the flow pipe body 1 to interrupt the pipe body heating. It is advantageous to have the safety thermostat with two poles.
