Description

Dieses Problem wird durch die im Patentanspruch
angegebene Erfindung gelöst.This problem is solved by the patent claim
specified invention solved.

Die mit der Erfindung erreichten Vorteile bestehen insbesonders darin, daß der Inhalt.der Thermoskanne sehr viel langer, bei Realisierung der Erfindung
nach Schutzanspruch 3..praktisch unbegrenzt, auf
einer für den Trinker optimalen Temperatur bleibt.The advantages achieved with the invention are in particular that the contents of the thermos flask are kept for much longer, when the invention is implemented
according to protection claim 3..practically unlimited, on
remains at an optimal temperature for the drinker.

Ein Ausführungsbeispiel der Erfindung ist in der
mit Figur 1. bezeichneten Zeichnung dargestellt und wird im folgenden näher beschrieben:An embodiment of the invention is described in
shown in the drawing marked Figure 1 and is described in more detail below:

In Figur 1. ist der Querschnitt einer Thermoskanne zu-sehen, wobei auf dem Boden des wärmeisolierten Bereichs der Kanne sich ein elektrischer Leiter (a) befindet, der durch Elektromagneten (b) die sich in einer Plattform (f) (auf die die Kanne bei Bedarf aufgesetzt werden kann) befinden, dadurch erhitzt wird, daß die Elektromagneten ein magnetisches
Wechselfeld erzeugen, daß in ihm Wirbelströmme
induziert. Der so erhitzte"Leiter gibt seine Wärme dann an die Flüssigkeit in der Thermoskanne ab. In diesem Ausführungsbeispiel ist auch noch eine
Regelung des beschriebenen Vorganges über einen
Thermostaten (d) vorgesehen, der seine Information über die Temperatur in der Kanne über einen
Wärmefühler (c) erhält , der über elektrische
Leiter mit ihm verbunden ist. Damit die Kanne
jederzeit problemlos auf die Plattform (f) gesetzt und genauso problemlos abgenommen werden kann, ist in diese Leiter der Steckkontakt (e) eingebaut.In Figure 1, the cross-section of a thermos flask is shown, whereby on the bottom of the heat-insulated area of the flask there is an electrical conductor (a) which is heated by electromagnets (b) located in a platform (f) (on which the flask can be placed if necessary) by the electromagnets forming a magnetic

Device according to protection claim 1. , characterized in that daß die Elektromagneten außen an der Kanne befestigt sind, und von einem Akku bzw. einer Batterie (die ebenfalls mit der Kanne verbunden sind), mit Strom versorgt werden.that the electromagnets are attached to the outside of the jug and are powered by a rechargeable battery or a battery (which are also connected to the jug). 3. Vorrichtung nach Schutzanspruch 1. , dadurch gekennzeichnet,3. Device according to protection claim 1. , characterized in that daß die Elektromagneten nicht an der Thermoskanne befestigt sind, sondern sich in einer z.B. vom öffentlichen Stromnetz gespeisten Feststation befinden, mit der die Thermoskanne nur bei Bedarf verbunden wird (z.B. durch einfaches Abstellen auf .einer Platte, in der sich die Elektromagneten befinden.)that the electromagnets are not attached to the thermos flask, but are located in a fixed station, e.g. powered by the public power grid, to which the thermos flask is only connected when necessary (e.g. by simply placing it on a plate in which the electromagnets are located). 4. Vorrichtung nach Schutzanspruch 1. sowie Schutzansprüchen 2. oder 3., dadurch gekennzeichnet,4. Device according to claim 1 and claims 2 or 3, characterized in that daß das Heizen der Thermoskanne über einen Thermostaten geregelt wird.that the heating of the thermos flask is controlled by a thermostat. BeschreibungDescription Dem Stand der Technik nach, gibt es soweit mir bekannt ist noch keinerlei Erfindungen, die der Abkühlung des Inhalts einer Thermoskanne entgegenwirken.According to the current state of technology, as far as I am aware, there are no inventions that counteract the cooling of the contents of a thermos flask. Der in den Schutzansprüchen angegebenen Erfindung liegt das Problem zugrunde, den Inhalt einer Thermoskanne möglichst lange warm zu haltenThe invention specified in the claims is based on the problem of keeping the contents of a thermos flask warm for as long as possible
