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
Generate alternating field that creates eddy currents
induced. The heated conductor then gives off its heat to the liquid in the thermos flask. In this embodiment, a
Control of the described process via a
Thermostat (d) is provided, which receives its information about the temperature in the pot via a
Heat sensor (c) which receives electrical
A conductor is connected to it. So that the jug
The plug contact (e) is built into this ladder so that it can be easily placed on the platform (f) at any time and just as easily removed.
