Description
Die vorliegende Neuerung betrifft einen Durchlauferhitzer für flüssige Medien gemäß dem Oberbegriff dee Sehutsanspruchs.The present innovation relates to a continuous flow heater for liquid media in accordance with the generic term of the protection claim.
Derartige, beispielsweise durch das DE-GM 86 05 223 bek«.iK3t gewordenen Durchlauferhitzer werden vielfach in Kaffeemaschinen od.dergl, eingebaut -aaa siv.d in der Regel so ausgelegt da3 sie bei Erreichen der Brüht essp era tür, bsr-w. bei Beendigung des Brühvorgangs abschalten, oder umschalten auf eine Temperatur, die zur WarmhaltuEg des aufgebrüfe&iacgr;«r: Kaffees genügt.Such continuous flow heaters, known for example from DE-GM 86 05 223, are often installed in coffee machines or similar - and are generally designed in such a way that they switch off when the brewing temperature is reached, or when the brewing process is finished, or switch to a temperature that is sufficient to keep the brewed coffee warm.
Zur Beschleunigung des Aufbrühens ging man schon dazu über, Rohrheizkörper mit Jjiher Leistungsaufnahme in den Durchlauferhitzer einzubauen. Dies hat jedoch zur Folge, daß in der Warmhaltephase, wenn also der Regler des Geräts den Rohrheizkörper auf eine niedrigere Leistung einregelt, ein gewisses Pendeln biiim Regelvorgang auftritt, was zu vorübergehenden Übertemperaturen führen kann. Dies sollte aber vermieden werden, da hierbei der Kaffee erneut zum Kochen kommen kann.In order to speed up the brewing process, tubular heating elements with a higher power consumption have been installed in the flow heater. However, this means that in the warming phase, when the device's controller sets the tubular heating element to a lower power, a certain amount of oscillation occurs in the control process, which can lead to temporary overheating. This should be avoided, however, as this can cause the coffee to boil again.
Es war daher Aufgabe dieser Neuerung, einen Durchlauferhitzer zu schaffen, der mit hoher Leistung rasch das Brühen des Kaffees bewirkt, der aber andererseits sicherstellt, daß der aufgebrühte Kaffee beim anschliessenden Warmhalten nicht mehr zum Kochen kommen kann.The aim of this innovation was therefore to create a continuous flow heater that would brew the coffee quickly with high performance, but which would also ensure that the brewed coffee would not boil again when it was subsequently kept warm.
Diese Aufgabe wird durch die im kennzeichnenden Teil des Schutzanspruchs beschriebenen Merkmale gelöst.This task is solved by the features described in the characterising part of the protection claim.
Der Gegenstand der Neuerung ist in einem Ausführungsbeispiel in der Zeichnung dargestellt und nachfolgend erläutert.The subject of the innovation is shown in an embodiment in the drawing and explained below.
3er dargestellt« Durchlauferhitzer besteht aus einem Stranggußteil 1 mit einem Durchflußkaxial 2 für das zu erhitzende Medium und aus zwei metallummantelten, verdichteten Rohrheizkörpern 3 und 4, die in zwei weiteren Bohrungen 5 und 6 des Stranggußteils 1 eingeschoben und mit letzterem verpreßt sind. Der Stranggußteil 1 weist außerdem eine Anlagefläche T auf, die zum Befestigen eines Temperaturreglers dient.3" continuous flow heater consists of a continuous casting 1 with a flow caxial 2 for the medium to be heated and of two metal-coated, compressed tubular heating elements 3 and 4, which are inserted into two further holes 5 and 6 in the continuous casting 1 and pressed onto the latter. The continuous casting 1 also has a contact surface T, which is used to attach a temperature controller.
Die elektrische Schaltung der beiden beschriebenen Rohrheizkörper 3 und 4 ist beispielsweise so ausgelegt, daß beim Einschalt. ten des Geräts zunächst beide Heizkörper in Parallelschaltung an Spannung gelegt werden und daß dann, nach Beendigung des Brühvorgangs, einer der Heizkörper abgeschaltet wird. Der noch verbleibende Heizkörper nimmt nun nicht nur erheblich weniger Leistung auf, sondern läßt sich damit auch wesentlich genauer regeln, so daß Überschreitungen der zulässigen Temperaturen sicher vermieden werden.The electrical circuit of the two tubular heating elements 3 and 4 described is designed in such a way that when the device is switched on, both heating elements are initially connected to voltage in parallel and then, once the brewing process has finished, one of the heating elements is switched off. The remaining heating element now not only consumes considerably less power, but can also be regulated much more precisely, so that exceeding the permissible temperatures is reliably avoided.
Ganz allgemein ist zu sagen, daß dieser neuartige Durchlauferhitzer auch für beliebig andere Zwecke verwendet werden kann, beispielsweise auch in eirer Bauart mit mehr als zwei Rohrheizkörpern. Durch die Möglichkeit der getrennten Schaltung der Heizkörper ist es ohne Probleme, den Durchlauferhitzer weitgehend und optimal an die gegebenen Betriebsbedingungen anzupassen. In general, it can be said that this new type of instantaneous water heater can also be used for any other purpose, for example in a design with more than two tubular heaters. The possibility of switching the heaters separately means that the instantaneous water heater can be adapted to the given operating conditions in the best possible way.
