Abstract

In an electrical continuous-flow heater for a drinks dispenser, a tube (1) is provided whose unobstructed passage is used for carrying the fluid which is to be heated. The jacket of the tube (1) has a helically running groove in which a tubular heating element (2) is embedded. The tubular heating element (2) is inserted at one end into an eye (1c) which is integrally formed on the tube (1) at one end of the groove. The groove has flanks which are pressed against the tubular heating body (2). As a result of the construction, there is no need to solder or weld the tubular heating body (2) in the groove. <IMAGE>

Description

Elektrischer Durchlauferhitzer für GetränkebereiterElectric water heater for beverage makers

Die Erfindung bezieht sich auf einen elektrischen Durchlauferhitzer für Getränkebereiter nach dem Oberbegriff des Anspruches 1.The invention relates to an electric water heater for beverage makers according to the preamble of claim 1.

Im Oberbegriff des Anspruches 1 wird von einem Durchlauferhitzer ausgegangen, wie er beispielsweise aus der DE-B1 II 39 589 bekannt geworden ist. Bei dem bekannten Durchlauferhitzer ist der Rohrheizkörper in der Nut des Rohres angeschweißt oder angelötet. Schweißen oder Löten sind Jedoch teure Arbeitsgänge, die zudem voraussetzen, daß der Mantel des Rohrheizkörpers und das Rohr aus Materialien bestehen, die schweiß- oder lötfähig sind (DE-B1 11 39 589).The preamble of claim 1 is based on a water heater, as has become known from DE-B1 II 39 589, for example. With the well-known Flow heater, the tubular heating element is welded or welded into the groove of the tube soldered on. However, welding or soldering are expensive operations that also require that the jacket of the tubular heater and the pipe are made of materials that are weldable or solderable (DE-B1 11 39 589).

Aufgabe der Erfindung ist es, den Durchlauferhitzer der im Oberbegriff des Anspruches 1 genannten Art so auszubilden, daß er mit einfachen Mitteln herstellbar ist und zu seiner Herstellung keine Schweiß- oder Lötvorgänge erforderlich sind.The object of the invention is to provide the water heater in the preamble of claim 1 mentioned type so that it can be produced with simple means and no welding or soldering processes are required for its manufacture.

Die gestellte Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruches 1 genannten Ausbildung gelöst.The object set is according to the invention by the in the characterizing Part of claim 1 mentioned training solved.

Eine zweckmäßige Aus- und Weiterbildung des Erfindungsgegenstandes ist im Anspruch 2 angegeben.An appropriate training and development of the subject matter of the invention is specified in claim 2.

Durch die gefundene Lösung kann die Vereinigung der den Durchlauferhitzer bildenden Elemente so erfolgen, daß ein gestreckter Rohrheizkörper mit einem Ende in den Tunnel des Rohres eingesteckt, sodann ein das Rohr haltender Wickelkopf einer Wickelvorrichtung in Drehung versetzt und der Rohrheizkörper unter Verformung zu einer Wendel in die Nut eingedrückt wird und daf3 nach dem Einlegen des Rohrheizkörpers in die Nut die Flanken der Nut an den Rohrheizkörper angepreßt werden. Das Anpressen der Flanken der Nut an den Rohrheizkörper kann im Zuge der Verformung des Rohrheizkörpers zu einer Wendel oder in einem gesonderten Arbeitsgang erfolgen.The solution found allows the union of the water heater forming elements are carried out in such a way that that an elongated tubular heater one end inserted into the tunnel of the pipe, then one holding the pipe Winding head of a winding device set in rotation and the tubular heating element under Deformation into a helix is pressed into the groove and daf3 after insertion of the tubular heating element in the groove, the flanks of the groove are pressed against the tubular heating element will. The pressing of the flanks of the groove against the tubular heating element can occur in the course of Deformation of the tubular heating element into a coil or in a separate operation take place.

Durch den Tunnel wird an der Wickelvorrichtung eine Einrichtung entbehrlich, mit welcher das-Jenige Ende des Rohrheizkörpers am Rohr gehalten wird, von dem die Verformung zu einer Wendel ausgeht.The tunnel makes a device superfluous on the winding device, with which the-Jenige end of the tubular heater is held on the pipe from which the Deformation to a helix originates.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung rein schematisch dargestellt.An embodiment of the invention is purely schematic in the drawing shown.

Es zeigen: Fig. 1 einen Aufriß, Fig. 2 eine Ansicht nach Linie II - II in Fig. 1, Fig. 3 einen Schnitt nach Linie III - III in Fig. 1.They show: FIG. 1 an elevation, FIG. 2 a view along line II - II in FIG. 1, FIG. 3 shows a section along line III - III in FIG. 1.

In der Zeichnung ist mit 1 ein Rohr bezeichnet, dessen lichter Durchgang 1a (Fig.3) zur Führung der aufzuheizenden Flüssigkeit dient1 Das Rohr 1 besteht vorzugsweise aus einem Guß- körper aus Leichtmetall und besitzt in seinem Mantel eine eingeformte schraubengangförmige Nut 1b (Fig.3), in der ein Rohrheizkörper 2 eingebettet ist.In the drawing, 1 denotes a tube whose clear passage 1a (Fig. 3) serves to guide the liquid to be heated 1 The pipe 1 consists preferably from one cast body made of light metal and possesses in its jacket a molded helical groove 1b (Figure 3), in which a Tubular heater 2 is embedded.

Am unteren Ende der Nut Ib des Rohres ist ein Auge 1c angeformt (Fig. 1 und 2).At the lower end of the groove Ib of the pipe, an eye 1c is formed (Fig. 1 and 2).

In das Auge 1c ist ein Ende des Rohrheizkörpers 2 so eingesteckt, daß ein zu diesem Ende gehörender Anschlußbolzen 2a des Rohrheizkörpers 2 frei zugängig ist (Fig. 1).One end of the tubular heater 2 is inserted into the eye 1c in such a way that that a connecting bolt 2a of the tubular heater 2 belonging to this end is freely accessible is (Fig. 1).

Die sich an das Auge 1c anschließende Nut Ib besitzt, wie besonders aus Fig. 3 ersichtlich, Flanken Id, die an den Rohrheizkörper 2 angepreßt sind.The groove Ib adjoining the eye 1c has, as is special from Fig. 3 it can be seen, flanks Id, which are pressed against the tubular heating element 2.

Die Tiefe der Nut Ib ist im dargestellten Beispiel so gewählt, daB sie den Rohrheizkörper 2 um mehr als 180° umschließt (Fig.3).The depth of the groove Ib is selected in the example shown so that it encloses the tubular heating element 2 by more than 180 ° (Fig. 3).

In der Zeichnung sind die Mittel zur Vereinigung des Rohrheizkörpers mit dem Rohrl und die Ausgangsform des Rohrheizkörpers 2 strichpunktiert dargestellt.In the drawing are the means for uniting the tubular heater with the Rohrl and the initial shape of the tubular heater 2 shown in phantom.

Das Bezugszeichen 3 in der Zeichnung gilt für einen Wickelkopf einer Wickelvorrichtung. Am Wickelkopf 3 ist ein Anschlag 3a vorgesehen (Fig.1).The reference number 3 in the drawing applies to a winding head Winding device. A stop 3a is provided on the winding head 3 (FIG. 1).

Mit 4 ist in Fig. 2 eine Andrückrolle bezeichnet.4 with a pressure roller is referred to in Fig. 2.

Zur Vereinigung des Rohrheizkörpers 2 mit dem Rohr 1 wird der gestreckte Rohrheizkörper 2 mit einem Ende in das Auge 1c soweit eingesteckt, bis der zugeordnete Anschlußbolzen 2a am Anschlag 3a anliegt (Fig.l). Sodann wird der Wickelkopf 3 in Drehung versetzt und mit der Andrückrolle 4 der Rohrheizkörper, unter Verformung zu einer Wendel in die Nut Ib eingepreßt. In einem besonderen Arbeitsgang oder unmittelbar nach dem Einlegen des Rohrheizkörpers 2, in die Nut Ib können die Flanken ld der Nut Ib an den Rohrheizkörper 2 angepreßt werden.To unite the tubular heater 2 with the tube 1, the stretched Tubular heater 2 with one end inserted into the eye 1c so far, until the associated connecting bolt 2a rests against the stop 3a (Fig.l). Then will the winding head 3 is set in rotation and with the pressure roller 4 the tubular heating element, pressed into the groove Ib while being deformed into a helix. In a special process or immediately after inserting the tubular heater 2, in the groove Ib can Flanks ld of the groove Ib are pressed against the tubular heater 2.

Die Teile 3, 3a und 4 sind nur dargestellt und beschrieben, um aufzuzeigen, mit welch einfachen Mitteln die Teile 1 und 2 durch die besondere Ausgestaltung des Rohres 1 vereinigbar sind.Parts 3, 3a and 4 are only shown and described to show With what simple means the parts 1 and 2 due to the special design of the pipe 1 can be combined.
