Description
Vorrichtung zum Anpressen eines biegsah."-elektrischen Heizkörpers, der unmittelbar - an den zu heizenden Stellen eines Gerätes anliegt Es ist bei elektrischen Heiz- und -Kochgeräten bereits bekannt, den Heizkörper mit einer Druckplatte an den zu heizenden- Körper anzupressen. Infolge der Unebenheiten der zu erwärmenden Geräte und Druckplatten liegt der elektrische Heizkörper an vielen Stellen hohl; es findet also hier eine schlechte Wärmeabnahme statt, und der Heizkörper kann durch Überhitzung geschädigt werden.Device for pressing a flexible "- electric heater, which is directly - at the points of a device to be heated. It is electrical Heating and cooking appliances already known to attach the radiator to a pressure plate to press the body to be heated. As a result of the unevenness of the to be heated Devices and pressure plates, the electric radiator is hollow in many places; So there is poor heat consumption here, and the radiator can get through Overheating.
Wohl hat man schon versucht, diese Hohlräume zu beseitigen, und zwar entweder durch Teilung der Druckplatten, die durch einen Bügel mittels einer Schraube angepreßt wurden, oder durch ein gewölbtes Element, das durch eine entgegengesetzt gewölbte Druckplatte an den Boden eines Gerätes gepreßt wurde, oder man versah Heizplatten mit starren Rippen, um eine gute plane Fläche zu schaffen,. um so -die Wäxme auf die daraufgestellten Gefäße u. dgl. zu übertragen. Auch Asbestplatten fanden zum Ausgleich der Unebenheiten Verwendung, die aber wegen ihrer geringen Nachgiebigkeit, zumal wenn Vertiefungen im Gerät oder in der Druckplatte waren, ihren Zweck nicht erfüllten. Hinzu kommt noch, _ daß Asbest hygroskopisch ist und bei höherer Temperatur verkohlt.Attempts have already been made to eliminate these cavities, and indeed either by dividing the pressure plates by means of a bracket by means of a screw were pressed, or by a curved element that is opposed by a domed pressure plate was pressed to the bottom of a device, or one provided heating plates with rigid ribs to create a good flat surface. all the more - the waxes up to transfer the vessels and the like placed thereon. Asbestos panels were also used Use to compensate for the unevenness, but because of its low flexibility, especially if there were depressions in the device or in the pressure plate, their purpose is not fulfilled. In addition, asbestos is hygroscopic and at higher temperatures charred.
Diese Übelstände werden gemäß der Erfindung dadurch beseitigt, daß zwischen dem Heizkörper und einer starren Druckplatte ein mit nachgiebigen Erhebungen versehenes Blech angeordnet ist. Beim Anziehen der Druckplatte drücken sich nun diejenigen Erhebungen des Bleches, die auf starken Widerstand stoßen, ein, diejenigen aber, die auf geringeren Widerstand stoßen, behalten entweder ihre Form bei oder drücken sich ein wenig ein, wodurch ein Ausgleich der Unebenheiten und gleichzeitig eine sehr gute Wärmeabnahme erreicht wird.These drawbacks are eliminated according to the invention in that between the radiator and a rigid pressure plate with resilient elevations provided sheet is arranged. When the pressure plate is tightened, they now squeeze those bumps in the sheet metal that encounter strong resistance, those but that encounter less resistance either retain their shape or press in a little, thereby compensating for the bumps and at the same time a very good heat dissipation is achieved.
Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel im Schnitt dargestellt. An dem äußeren Boden b des Kochtopfes a befindet sich der elektrische Heizkörper c, auf welchem das mit nachgiebigen Erhebungen e versehene Blech d ruht, das durch die Druckplatte f vermittels der Schraube g auf den Heizkörper c und dieser Wiederum auf den Boden b des Topfes a gepreßt wird. Es ist ersichtlich, daß die Erhebungen e ihre Form nicht verändert haben, wohl aber die Erhebungen i, da: sie infolge der hier vorhandenen Ausbuchtung des Topfes einer starken Pressung ausgesetzt sind. Die Formen der nachgiebigen Erhebungen des Bleches d können beliebig sein.In the drawing, the invention is shown in one embodiment Section shown. The electric one is on the outer bottom b of the saucepan a Radiator c, on which the sheet metal d provided with flexible elevations e rests, through the pressure plate f by means of the screw g on the radiator c and this Again on the bottom b of the pot a is pressed. It can be seen that the Elevations e have not changed their shape, but elevations i, da: they exposed to strong pressure due to the bulge of the pot that is present here are. The shapes of the resilient elevations of the sheet metal d can be of any desired type.
