Description

Die Erfindung betrifft einen zur Erwärmung von Flüssigkeiten dienenden elektrischen Durchlauferhitzer gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an electrical serving for heating liquids Instantaneous water heater according to the preamble of patent claim 1.

Derartige, mit Rohrheizkörpern ausgerüstete Durchlauferhitzer, sind gewöhnlich mit einem Temperaturregler versehen, der mit diesen thermisch gekoppelt ist.Such instantaneous water heaters equipped with tubular heaters are common provided with a temperature controller that is thermally coupled to these is.

Bei dieser an sich einfachen Temperaturregelung ist jedoch zu beachten, daß erhebliche Temperaturunterschiede zwischen dem Rohrheizkörper und der durchströmenden Flüssigkeit auftreten, die bis ca. 80 Grad C betragen können. Wird der Regler am Durchlaufrohr angebracht, so wird die Temperatur wohl genau erfaßt, doch wird nach dem Abschalten des Heizkörpers die noch in diesem vorhandene Wärmemenge in die relativ kleine Flüssigkeitsmenge im Durchlaufrohr nachgeschoben, so daß, beispielsweise bei Wasser, die Verdampfungstemperatur überschritten werden kann, also Wasserdampf im System entsteht, was unerwünscht ist.With this simple temperature control, however, it should be noted that considerable temperature differences between the tubular heater and the flowing liquid occur, which are up to about 80 degrees C. can. If the controller is attached to the flow tube, the temperature probably recorded exactly, but after switching off the radiator still present in this amount of heat in the relatively small amount of liquid pushed in the flow tube, so that, for example in the case of water, the evaporation temperature can be exceeded, i.e. water vapor in the System is created, which is undesirable.

Durch die DE-OS 25 00 287 ist es bekannt, den Rohrheizkörper und das Durchflußrohr in ein Metallformteil einzugießen und den Temperaturregler in einer Aussparung dieses Formteils anzuordnen. Diese Ausführungsart stellt jedoch ein starres Gebilde dar, das in seiner Form nicht mehr verändert, also auch nicht mehr angepaßt werden kann.From DE-OS 25 00 287 it is known the tubular heater and the flow tube Pour into a molded metal part and the temperature controller in one To arrange recess of this molding. However, this type of execution represents a rigid structure that no longer changes in shape, so also can no longer be adjusted.

Bei einem weiteren, durch die DE 31 12 651 C2 bekannt gewordenen Durchlauferhitzer ist die nachträgliche Verformbarkeit wohl in gewissen Grenzen gegeben, doch läßt sich, bedingt durch diese Bauart, ein Temperaturregler nicht so anbringen, daß er die unterschiedlichen Temperaturen von Rohrheizkörper und Durchlaufrohr erfassen kann.In a further water heater, which has become known from DE 31 12 651 C2 is the subsequent deformability probably within certain limits, however, due to this design, a temperature controller cannot be used Attach so that the different temperatures of tubular radiators and can detect flow tube.

Es war daher Aufgabe der vorliegenden Erfindung, einen Durchlauferhitzer zu schaffen, der nach seiner Fertigstellung noch in ausreichendem Maße biegefähig, also anpassungsfähig ist und der eine Meßstelle aufweist, an der sich eine vom Temperaturregler erfaßbare Mischtemperatur einstellt.It was therefore an object of the present invention to provide a water heater to create the sufficient after its completion bendable, that is adaptable and which has a measuring point which sets a mixing temperature that can be detected by the temperature controller.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. This object is achieved by the characterizing features of the patent claim 1 solved.  

Mit dieser Anordnung wird erreicht, daß sich an der Meß­ stelle eine Mischtemperatur einstellt, die auch von ei­ nem einfachen Temperaturregler, beispielsweise einem Bi­ metallregler erfaßt werden kann, der dann rechtzeitig ab­ schaltet, so daß Überhitzungen ausgeschlossen sind.This arrangement ensures that the measurement set a mixing temperature that also from egg nem simple temperature controller, for example a Bi metal regulator can be detected, which then on time switches so that overheating is impossible.

Der Gegenstand der Erfindung ist in einem Ausführungsbei­ spiel in der Zeichnung dargestellt und nachfolgend be­ schrieben.The object of the invention is in one embodiment game shown in the drawing and below be wrote.

Es zeigenShow it

Fig. 1 den Durchlauferhitzer in einer Seitenansicht, Fig. 1 shows the water heater in a side view;

Fig. 2 einen Querschnitt in der Ebene II : II der Fig. 1 und Fig. 2 shows a cross section in the plane II: II of Fig. 1 and

Fig. 3 den Durchlauferhitzer gemäß Fig. 1 in der Draufsicht. Fig. 3 shows the water heater according to FIG. 1 in plan view.

Der dargestellte Durchlauferhitzer besteht aus einem bei­ spielsweise aus Aluminium bestehenden Strangpreßteil 1, einem U-förmig gebogenen, in das Strangpreßteil eingescho­ benen Durchlaufrohr 2 und einem zwischen den beiden Schen­ keln des Durchflußrohres 2 im Strangpreßteil angeordneten Rohrheizkörper 3 mit den auf beiden Seiten des Strangpreß­ teils 1 herausragenden elektrischen Anschlüssen 4. The water heater shown consists of an extrusion 1 , for example made of aluminum, a U-shaped bent, inserted into the extrusion part of the flow tube 2 ben and a between the two legs of the flow tube 2 arranged in the extrusion tube heater 3 with the part on both sides of the extrusion 1 outstanding electrical connections 4 .

Die Teile 1-3 dieses Aufbaus sind miteinander verpreßt, so daß eine ebene Anlagefläche 5 verbleibt, die sich über die Schenkel des Durchlaufrohres 2 und den Rohrheizkörper 3 erstreckt.The parts 1-3 of this structure are pressed together, so that a flat contact surface 5 remains, which extends over the legs of the flow tube 2 and the tubular heater 3 .

Auf dieser Anlagefläche 5 ist ein Temperaturregler 6, an sich bekannter Art, beispielsweise ein Bimetallregler auf­ gesetzt und mittels einer, in Form eines Bügels gestalte­ ten Blattfeder 8, die um das Strangpreßteil 1 herumgreift, befestigt. Der elektrische Anschluß des Reglers 6 erfolgt über die beiden Kontaktfahnen 9 desselben.On this contact surface 5 is a temperature controller 6 , known per se, for example a bimetallic controller, and is fastened by means of a leaf spring 8 , which is designed in the form of a bracket and which engages around the extrusion 1 . The electrical connection of the controller 6 takes place via the two contact lugs 9 of the same.

Selbstverständlich kann in den Reglerstromkreis auch noch ein übergeordnetes Regelorgan, beispielsweise eine Schmelz­ sicherung, eingeschaltet werden.Of course, you can also add to the controller circuit a higher-level control element, for example an enamel fuse, be switched on.

Ergänzend wird hinzugefügt, daß für den Fall, daß kleine Baulängen des Durchlauferhitzers gefordert sind, der Er­ hitzer nach dem Verpressen der Bauteile 1 bis 3 noch zu­ sätzlich U-förmig gebogen werden kann.In addition, it is added that in the event that small lengths of the instantaneous water heater are required, the heater can also be bent into a U-shape after the pressing of components 1 to 3 .
