  Elektrisch beheizter Kochtopf oder Kochkessel 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 Fühler 6a infolge der Wärmeübertragung durch den Kesselboden indirekt durch die Heizflüssigkeit Diäthylenglykol 5 beeinflusst und der Heizstrom abgeschaltet. Diese Doppelfunktion des Thermostaten 6 bzw. des zugehörigen Fühlers 6a wird, wie insbesondere aus Fig. 2 ersichtlich, dadurch erreicht, dass am Boden des Kochkessels 1 ein Röhrchen 6b aus Material mit hoher Wärmeleitfähigkeit z. B. Kupfer derart befestigt wird (löten, schweissen u.   ähnl.),   dass eine intensive Wärmeübertragung ge-   währleistet ist. Die Abmessungen des Röhrchens   6b entsprechen denen des Fühlers 6a, so dass dieser   genau in das Röhrchen 6b eingeschoben werden kann.

   Das Röhrchen   6b mit dem Fühler 6a wird von einer Kapsel 7 aus Metall derart abgedeckt bzw. abgedichtet, dass das Röhrchen 6b mit dem Fühler 6a nicht mit der Heizflüssigkeit Diäthylenglykol 5, in Berührung kommen kann. Der zwischen der Kapsel 7 und dem Röhrchen 6b verbleibende Raum 8, der mit Isoliermaterial ausgefüllt sein kann, ist derart bemessen, dass der Inhalt des Kochkessels bzw. dessen Temperatur zuverlässig den Fühler 6a des Thermostaten 6 beeinflusst, bei leerem Kochkessel 1 jedoch die Wärme- übertragung von der Heizflüssigkeit 5 durch den Boden des Kochkessels 1 mit Sicherheit derart erfolgt, dass auch bei Einstellung der höchstmöglichen Temperatur (zirka 120 C) die Heizflüssigkeit 5 auf nicht mehr als etwa   150 C erhitzt   werden kann bzw.

   eine bestimmte maximale Temperaturdifferenz zwischen der eingestellten Temperatur und der der Heizflüssigkeit gewährleistet ist. Diese Anordnung des Thermostaten 6 bzw. des Fühlers 6a in Verbindung mit der Verwendung von Diäthylenglykol als Heizflüssigkeit sichert eine einwandfreie Temperaturregelung für den Inhalt des Kochkessels 1 und einen praktisch wartungsfreien Betrieb von Kochkesseln gemäss der Erfindung. 



   Mit den dargestellten und beschriebenen Ausführungsbeispielen ist die Erfindung jedoch keineswegs erschöpft, sondern kann noch im Rahmen ihrer Grundgedanken auf verschiedene Art und Weise verwirklicht werden. 



   Kochkessel gemäss der Erfindung können auch als Kippkessel verwendet werden, wobei jedoch durch eine mechanische oder elektrische magnetische Sperre der Kessel erst nach Abschalten des Heizstromes zum Entleeren gekippt werden kann.

  Electrically heated saucepan or kettle
 EMI1.1
 

 <Desc / Clms Page number 2>

 Sensor 6a indirectly influenced by the heating fluid diethylene glycol 5 as a result of the heat transfer through the boiler bottom and the heating current is switched off. This dual function of the thermostat 6 and the associated sensor 6a is achieved, as can be seen in particular from FIG. 2, in that a tube 6b made of material with high thermal conductivity, e.g. B. copper is attached in such a way (soldering, welding, etc.) that an intensive heat transfer is guaranteed. The dimensions of the tube 6b correspond to those of the sensor 6a, so that it can be pushed precisely into the tube 6b.

   The tube 6b with the sensor 6a is covered or sealed by a capsule 7 made of metal in such a way that the tube 6b with the sensor 6a cannot come into contact with the heating liquid diethylene glycol 5. The space 8 remaining between the capsule 7 and the tube 6b, which can be filled with insulating material, is dimensioned such that the contents of the cooking kettle or its temperature reliably influences the sensor 6a of the thermostat 6, but when the kettle 1 is empty, the heat The transfer of the heating liquid 5 through the bottom of the cooking vessel 1 is certain to take place in such a way that the heating liquid 5 cannot be heated to more than about 150 ° C. even when the highest possible temperature is set (approximately 120 ° C.).

   a certain maximum temperature difference between the set temperature and that of the heating fluid is guaranteed. This arrangement of the thermostat 6 or the sensor 6a in conjunction with the use of diethylene glycol as heating fluid ensures perfect temperature control for the contents of the cooking vessel 1 and practically maintenance-free operation of cooking vessels according to the invention.



   The illustrated and described exemplary embodiments, however, by no means exhaust the invention, but can still be implemented in various ways within the framework of its basic ideas.



   Cooking kettles according to the invention can also be used as tilting kettles, but by means of a mechanical or electrical magnetic lock the kettle can only be tilted for emptying after the heating current has been switched off.
