Description
Diese Erfindung betrifft ein Verfahren zur Herstellung von Verdampfern für Kühlgeräte, insbesondere für Haushaltskühlschränke, und den hergestellten Verdampfer. Sowohl das Verfahren als auch der hergestellte Verdampfer sind von der Art, wie sie im Oberbegriff der beigefügten Hauptansprüche angeführt ist, auf die hier Bezug genommen wird.This The invention relates to a method for producing evaporators for cooling devices, in particular for household refrigerators, and the evaporator manufactured. Both the procedure and the Manufactured evaporators are of the type in the preamble the attached all claims cited is referred to here.
Die italienische Patentanmeldung MI96A000895, die am 5.6.1996 angemeldet wurde, beschreibt ein Verfahren zur Herstellung von Verdampfern und einen durch das Verfahren hergestellten Verdampfer. Bei dieser Patentanmeldung ist ein gemäß einer Haarnadelkurve gebogenes Rohr mindestens längs seiner geradlinigen Teile zwischen zwei Blechen angeordnet, die miteinander und mit den genannten Teilen mittels Klebstoffs verbunden sind, der auf einem der Bleche aufgetragen ist. Dieses Blech ist auch auf seiner Außenseite mit Klebstoff versehen, um den Verdampfer am Kühlschrankfach befestigen zu können, an dessen Form der Verdampfer durch Biegen angepasst ist.The Italian patent application MI96A000895, filed on June 5, 1996 describes a process for the production of evaporators and an evaporator made by the method. At this Patent application is a according to one Hairpin curved tube at least along its straight parts arranged between two sheets, one with the other and with the above Parts are connected by means of adhesive on one of the sheets is applied. This sheet is also on its outside provided with adhesive to attach the evaporator to the refrigerator compartment can, the shape of the evaporator is adapted by bending.
In Kühlgeräten, die mit zwei Fächern für die Frischhaltung von Nahrungsmitteln bei verschiedenen Temperaturen versehen sind, nämlich ein Fach für das Gefrieren und ein Fach für das Kühlen, werden zwei getrennte Verdampfer verwendet, die in Reihe geschaltet und durch Schweißungen miteinander verbunden sind, wodurch eine beträchtlicher Arbeitsaufwand entsteht.In Refrigerators that with two compartments for keeping fresh are provided with food at different temperatures, namely a compartment for freezing and a compartment for cooling, two separate evaporators are used, which are connected in series and through welds are interconnected, which creates a considerable amount of work.
Die Hauptaufgabe der Erfindung besteht darin, die Notwendigkeit dieser Schweißungen durch Schaffung eines einteiligen Verdampfers zu vermeiden, dessen beide Abschnitte beide Fächer des Kühlgeräts erfassen.The Main object of the invention is the need for this welds by creating a one-piece evaporator whose both sections both subjects of the refrigerator.
Diese Aufgabe und weitere Aufgaben gehen klarer aus der folgenden, ausführlichen Beschreibung hervor und werden durch ein Verfahren gemäß Anspruch 1 und einen Verdampfer gemäß Anspruch 6 gelöst. Die Unteransprüche beschreiben weitere Ausführungen der Erfindung.This Task and other tasks are clearer from the following detailed Description and are by a method according to claim 1 and an evaporator according to claim 6 solved. The subclaims describe further explanations the invention.
Die Erfindung geht klarer aus der folgenden, ausführlichen Beschreibung eines bevorzugten, den Schutzumfang nicht beschränkenden Ausführungsbeispiels anhand der beigefügten Zeichnungen hervor. Es zeigen:The The invention will be more apparent from the following detailed description of preferred, the scope of protection not limiting embodiment based on the attached Drawings. Show it:
In
den Figuren bezeichnet das Bezugszeichen
Der Verdampfer gemäß der Erfindung dient sowohl für das Kühlfach als auch für das Gefrierfach, trotz der Tatsache, dass er einstückig in dem Sinn ausgebildet ist, dass die betroffene Rohrschlange keine Unstetigkeit aufweist, wie sie beispielsweise beim Schweißen auftritt.The Evaporator according to the invention serves both for the refrigerator compartment for as well the freezer, despite the fact that it is in one piece the sense is that the pipe coil concerned is none Has discontinuity, such as occurs during welding.
Bei
dem in den Zeichnungen dargestellten Ausführungsbeispiel ist angenommen
worden, dass das Kühlfach
sieben geradlinige Teile
Auf
den beiden Seiten der Linie R haben die benachbarten, geradlinigen
Rohrschlangenteile

der Teile
Die
vorgenannten Vorgänge
können
auch mit der Hand oder durch andere Mittel, die automatische Mittel
einschließen
und sich von denen des gezeigten Beispiels unterscheiden, ausgeführt werden. Die
wichtigsten Gesichtspunkte sind das Vorhandensein zweier benachbarter,
geradliniger Teile
Das
Rohr
Gemäß einem
besonderen Aspekt ist ein elektrisches Widerstandselement (in Form
eines elektrisch isolierten Widerstandsdrahts) zwischen den Blechen
Mit
der Rohrschlange ist ein übliches
Kapillarrohr
Die genannte Verbindung ist einfach als Ergebnis der „Vorformung" des Verdampfers auszuführen, bei der dieser an das genannte Fach in geeigneter Weise angepasst wird. Der Verdampfer weist auch Verdampferabschnitte auf, die trotz ihrer Unterschiedlichkeit ohne Schweißung miteinander verbunden sind, so dass der fertige Verdampfer damit einstückig ausgebildet ist.The said connection is simple as a result of the "preforming" of the evaporator perform, in which this is appropriately adapted to the subject mentioned becomes. The evaporator also has evaporator sections that despite their diversity connected without welding are, so that the finished evaporator is thus formed in one piece.
Bei
einer weiteren Ausführung
gemäß der Erfindung
ist mindestens ein Blech der Bleche
Der hier verwendete Ausdruck „Gefrierfach" bezeichnet ein Fach, in dem das Lebensmittelprodukt im gefrorenen Zustand aufbewahrt wird und/oder in diesen Zustand gebracht werden kann.The The term "freezer compartment" used here denotes a compartment in which the food product is kept frozen and / or can be brought into this state.
