Description

Verfahren zum Verlöten von elektrischen Heizvorrichtungen, die einen eingeschlossenen Heizkörper haben. Bei der Herstellung von elektrischen Heizuni Kochvorrichtungen ist vor und nach dem Verlöten des den Heizwiderstand aufnehmenden Behälters eine Prüfung erforderlich, ob der Heizkörper die gewünschte Heizenergie leistet und die Isolation gegen das Gehäuse eine vollkommene ist. Hierzu und zu dem eigentlichen Verlöten sind verschiedene Arbeitsgänge nötig.Method of soldering electrical heating devices that have a have enclosed radiators. In the manufacture of electrical heating uni Cooking devices is before and after the soldering of the heating resistor A check is required to determine whether the radiator has the desired heating energy and the insulation against the housing is perfect. To this and to The actual soldering requires different operations.

Die vorliegende Erfindung ermöglicht die Ausführung der verschiedenen Arbeiten in einem einzigen Gang.The present invention enables the various Working in a single aisle.

Das hierzu dienende Verfahren besteh darin, daß der in die Heizvorrichtung eingebaute Heizkörper unter Strom gesetzt und so geregelt wird, bis er die gewünschte Heizenergie erreicht. Diese Heizenergie bewirkt zugleich das Austrocknen der Vorrichtung im Ganzen und ihrer Teile, namentlich der zur Isolation dienenden, wie Asbest-, 1likaniteinlagen u. dgl. Infolge des auf diese Weise herbeigeführten gleichmäßigen Erwärmens ist ein Schwitzen, wie es bei dem Löten mittels Stichflamme oder Lötkolbens auftritt, infolge der nur örtlichen Erhitzung, die heiße Stellen neben kalten entstehen läßt, ausgeschlossen. Bevor die Löttemperatur erreicht ist, ist also der Teil, in welchem sich der Heizkörper befindet, in seinem Innern vollkommen ausgetrocknet. Die gleichmäßige Erhitzung des Heizkörpers bewirkt aber auch eine solche des umschließenden Behälters, so daß dieser auf seinem ganzen Umfang an der Lötnaht die erforderliche Löttemperatur aufweist. Sobald diese erreicht ist, wird der Strom unterbrochen, und das Verlöten des Behälters erfolgt dann lediglich durch Überfahren der Naht mit dem Lot.The method used for this is that the in the heating device built-in radiator is energized and regulated until it is the desired one Heating energy reached. This heating energy also causes the device to dry out as a whole and its parts, especially those used for insulation, such as asbestos, 1likaniteinlagen and the like as a result of the uniformity brought about in this way Warming up is sweating, as is the case with soldering with a jet flame or a soldering iron occurs as a result of the local heating that creates hot spots next to cold ones leaves, excluded. So before the soldering temperature is reached, the part is in which the radiator is located, completely dried out inside. The even heating of the radiator also causes the surrounding one Container, so that this is the required on its entire circumference at the soldered seam Has soldering temperature. As soon as this is reached, the current is interrupted, and the container is then simply soldered by driving over the seam with the plumb bob.

Der Lötvorgang kann noch dadurch erleichtert und beschleunigt werden, daß die Heizvorrichtung durch Aufsetzen auf einen Drehteller eine Eigendrehung erfährt. Nach Schließung der Lötfuge kann man das an dem noch heißen Heizmittelbehälter belassene Luftloch durch einen darauf aufgebrachten Löttropfen vollkommen abschließen, worauf die Vorrichtung dein Abkühlen überlassen wird.The soldering process can be made easier and faster, that the heater experiences its own rotation by placing it on a turntable. After the solder joint has been closed, what is left on the still hot heating medium container can be used Completely close the air hole with a drop of solder applied to it, whereupon the device is left to cool.

Da gleichzeitig mehrere Heizvorrichtungen unter Strom gesetzt werden können, kann ein einziger Arbeiter deren mehrere gleichzeitig verlöten, um so mehr, wenn sie sich dabei auf einer gemeinsamen Drehscheibe befinden.Because several heating devices are energized at the same time a single worker can solder several of them at the same time, all the more so, if they are on a common turntable.

Die Vorteile dieses Verfahrens gegenüber demjenigen mittels Gasstichflamme oder Lötkolbens liegen in der wesentlichen Abkürzung des Lötvorganges selbst, Herbeiführung des Austrocknens des Heizkörpers und Verhinderung der Bildung von Niederschlagswasser sowie Vereinigung des Lötvorganges mit demjenigen der elektrischen Prüfung. Dabei fällt die Naht sehr sauber aus, der Behälter leidet nicht unter der unmittelbaren Berührung der Flamme, läuft also nicht an und wird nicht verschmiert, und die Isolation wie auch die Lebensdauer der Heizvorrichtung wird infolge des Austrocknens derselben vor dem Abschließen gegen die Außenluft erhöht.The advantages of this method compared to using a gas stick flame or soldering iron lie in the essential abbreviation of the soldering process itself, bringing about drying out the radiator and preventing the formation of rainwater as well as unification of the soldering process with that of the electrical test. Included if the seam is very clean, the container does not suffer from the immediate Touching the flame, so does not start and is not smeared, and the insulation as well as the life of the heater is due to drying out thereof increased before locking against the outside air.
