  Heizelement für Vorrichtungen zum elektrischen Erhitzen strömender   Flü88igkeiten.   



   Die vorliegende Erfindung bezieht sich auf einen   Durchnussapparat   zur Erhitzung von Flüssigkeiten mit Hilfe eines elektrischen Stromes. Es ist bekannt, eine Flüssigkeit durch ein   Röhrensystem   zu führen, das von elektrischen Heizspiralen umgeben ist und mit Hilfe dieser Heizspiralen eine dauernde Erwärmung der   durchfliessenden   Flüssigkeit zu bewirken. Doch 
 EMI1.1 
 sich wieder auf einen bestimmten Grad abgekühlt hat denn die bisher bekannten Konstruktionen   besitzen einerseits eine grosse eigene Masse, die erwärmt bzw. abgekühlt werden muss,   und ferner ist die jeweilig in dem Apparat vorhandene Wassermenge verhältnismässig gross. Die vorliegende Konstruktion vermeidet diese Übelstände vollkommen. da auch bei den grössten Leistungen 
 EMI1.2 
 selber ausserordentlich gering ist.

   Dadurch wird es erreicht, dass beispielsweise schon für mittlere Leistungen, d. h. für Leistungen von   I   bis 5 Kilowatt. eine Erhitzung von kaltem Wasser zum Kochen innerhalb weniger (8 bis 10) Sekunden erfolgt und ein derartiger an die Wasserleitung   angeschraubter Apparat daher fast augenblichklich kochendes Wasser liefert. Die Abkühlung   von kochend auf kalt erfolgt bei einem derartigen Apparat innerhalb etwa   2 Sekunden. Bei   grösseren Leistungen verkürzt   sieh noch diese Zeitdauer.   Die   Beschreibung möge   an Hand der Zeichnung näher erfolgen. Der Apparat besteht aus einem langgestreckten Heizelement, das zu einer Spirale   zusammengewickelt wird.   



   Fig. 1 zeigt einen Schnitt durch das Heizelement. Die Umwandlung des elektrischen

  Heating element for devices for the electrical heating of flowing liquids.



   The present invention relates to an apparatus for heating liquids with the aid of an electric current. It is known to guide a liquid through a pipe system which is surrounded by electrical heating coils and to bring about permanent heating of the liquid flowing through with the aid of these heating coils. But
 EMI1.1
 has cooled down again to a certain degree because the previously known constructions have, on the one hand, a large mass of their own that must be heated or cooled, and furthermore the amount of water present in the apparatus is relatively large. The present construction completely avoids these inconveniences. there even with the greatest achievements
 EMI1.2
 itself is extremely small.

   It is thereby achieved that, for example, even for medium performance, i. H. for outputs from 1 to 5 kilowatts. a heating of cold water to boil takes place within a few (8 to 10) seconds and such an apparatus screwed to the water pipe therefore supplies almost instantly boiling water. The cooling from boiling to cold takes about 2 seconds in such an apparatus. This period is shortened for greater performance. The description should be based on the drawing. The apparatus consists of an elongated heating element that is wound into a spiral.



   Fig. 1 shows a section through the heating element. The conversion of the electrical
 EMI1.3
 Plates the inflow or outflow of the fluids takes place to the center of the spiral.

PATENTANSPRUCH : Heizelement für Vorrichtungen zum elektrischen Erhitzen strömender Flüssigkeiten, bestehend aus einem bandförmigen Leiter, der unter Zwischenlagerung von Isolierschichten mit einem Metallmantel umpresst ist, dadurch gekennzeichnet. dass der Metallmantel an den Rändern Wulste besitzt, so dass beim Zusamunnrollen des Heizelemente8 zu einer Spirale ein flacher Kanal für den Durchfluss der zu erwärmenden Flüssigkeit gebildet wird. PATENT CLAIM: Heating element for devices for the electrical heating of flowing liquids, consisting of a strip-shaped conductor, which is pressed around with a metal jacket with intermediate storage of insulating layers, characterized. that the metal jacket has bulges at the edges, so that when the heating element8 is rolled up to form a spiral, a flat channel is formed for the flow of the liquid to be heated.
