Abstract

The heater has the passage tube (2) designed in a U-shape, and the tubular heater (3) is arranged between the tube limbs. The temp. regulator (6) is fitted at a flat shaped covering surface (5) of the extruded part (1), overlapping the region of the passage tube (2) and the tubular heater (3). The temp. regulator (6) is fitted by means of a bracket shaped leaf spring (8) gripping around the extruded part (1). When small constructional lengths are required, the heater following the extrusion of the parts (1-3) can additionally be bent in a U-shape. ADVANTAGE - Ensures better temp. regulation so that e.g. water as medium steam is kept out of system.

Description

Die Erfindung betrifft einen zur Erwärmung von Flüssigkei­ ten dienenden elektrischen Durchlauferhitzer gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a for heating liquids serving electrical instantaneous water heater according to the Preamble of claim 1.

Derartige, mit Rohrheizkörpern ausgerüstete Durchlauferhit­ zer, sind gewöhnlich mit einem Temperaturregler versehen, der mit diesen thermisch gekoppelt ist.Such flow heater equipped with tubular heating elements zer, are usually equipped with a temperature controller, which is thermally coupled to these.

Bei dieser an sich einfachen Temperaturregelung ist jedoch zu beachten, daß erhebliche Temperaturunterschiede zwi­ schen dem Rohrheizkörper und der durchströmenden Flüs­ sigkeit auftreten, die bis ca. 80 Grad C betragen kön­ nen. Wird der Regler am Durchlaufrohr angebracht, so wird die Temperatur wohl genau erfaßt, doch wird nach dem Abschalten des Heizkörpers die noch in diesem vor­ handene Wärmemenge in die relativ kleine Flüssigkeits­ menge im Durchlaufrohr nachgeschoben, so daß, beispiels­ weise bei Wasser, die Verdampfungstemperatur überschrit­ ten werden kann, also Wasserdampf im System entsteht, was nicht erwünscht ist.With this simple temperature control, however, is to note that considerable temperature differences between between the tubular heater and the flowing rivers fluidity that can be up to approx. 80 degrees C. nen. If the controller is attached to the flow tube, so the temperature is probably recorded exactly, but will before switching off the radiator available amount of heat in the relatively small liquid amount added in the flow tube so that, for example with water, the evaporation temperature exceeds water vapor in the system, which is what is not desired.

Um dies zu verhindern wird vorgeschlagen, die thermische Ankoppelung des Rohrheizkörpers an das Durchlaufrohr we­ sentlich zu verbessern und den Temperaturregler so an dem den Rohrheizkörper und das Durchlaufrohr umfassenden Strang­ preßteil anzuordnen, daß die sich einstellende Mischtempe­ ratur vom Regler abgetastet wird.To prevent this, the thermal is proposed Coupling the tubular heater to the flow tube we to improve considerably and so the temperature controller the tubular heater and the continuous pipe strand Arrange the press part that the mixing temp is scanned by the controller.

Gemäß vorliegender Erfindung wird diese Aufgabe dadurch gelöst, daß innerhalb des Strangpreßteils der Rohrheiz­ körper zwischen den Schenkein des U-förmig gebogenen Durch­ laufrohres angeordnet wird und der Regler an einer flach gestalteten, die Bereiche des Durchlaufrohres und des Heiz­ körpers überbrückenden Fläche des Strangpreßteils ange­ bracht wird.According to the present invention, this object is achieved solved that within the extrusion of the tubular heating  body between the legs of the U-shaped bent through Running tube is arranged and the regulator on a flat designed the areas of the flow pipe and the heating body bridging surface of the extruded part is brought.

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.

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 kein 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 and one of the flow tubes 2 in the extrusion part arranged tubular 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, in the form of a bracket, a leaf spring 8 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 .
