Description

Elektrisch heizbares Porzellangefäß. Vorliegende Erfindung ,bezieht sich. auf elektrisch beheizte Porzellangefäße. Solche sind bereits bekannt, und zwar hat man bisher die Heizspiralen am Boden und an einem Teil der Wandungen der Porzellangefäße angebracht. Dies ,hat aber iden Nachteil, daß die Porzellangefäße springen, sobald die elektrische Heizung .in. Gang gesetzt :und das Gefäß mit Flüssigkeit nur so weit angefüllt ist, daß deren Spiegel unterhalb eines Teiles der die Wandungen umgebenden Wicklungen liegt. Demgegenüber besteht d!ie Erfindung .darin, daß d.ie Heizspirale nur auf -der äußeren Bodenfläche der Gefäße angeordnet sind. Eine solche Anordnung ist allerdings bei Metallgefäßen bereits .bekannt, indessen tritt die erwähnte Wirkung erst bei. Porzellangefäßen zutage. Denn bei aus Metall hergestellten Kochgefäßen ist wegen der guten WärmeleitungsfähIgkeit des M etalls ein Springen der Gefäßwandungen auch dann nicht izu befürchten, wenn di.e Heizspiralen nicht nur am Boden, -sondern auch an einem Teil der Wandungen angebracht sind, und,der Flüssigkeitsspiegel unterhalb der oberen Grenze der Heizspiralen liegt. Die Erfindung ist auf der Zeichnung in einem Ausführungsbeispyiel ,dargestellt, und zwar zeigt Abb. i Idas Kochgefäß in einem senkrechten Schnitt nebst einer am Boden vorgesehenen Schutzhülse und Abb.2 eine Unteransicht des Kochgefäßbodens mit geschnittener Schutzhülse.Electrically heatable porcelain vessel. The present invention relates themselves. on electrically heated porcelain vessels. Such are already known, and although one has so far the heating coils on the floor and on part of the walls of the Porcelain vessels attached. This, however, has the same disadvantage that the porcelain vessels jump as soon as the electric heater .in. Gear set: and the vessel with liquid is filled only so far that its mirror is below part of the walls surrounding windings. In contrast, the invention consists in that the Heating coil are only arranged on the outer bottom surface of the vessels. Such However, the arrangement is already known for metal vessels mentioned effect only at. Porcelain vessels come to light. Because with made of metal Because of the good thermal conductivity of the metal, cooking vessels are cracking there is no need to fear the vessel walls even if the heating coils are not are only attached to the floor, but also to part of the walls, and, the Liquid level is below the upper limit of the heating coils. The invention is shown on the drawing in an exemplary embodiment, namely shows Fig. I Ida's cooking vessel in a vertical section along with one provided on the floor Protective sleeve and Fig. 2 a view from below of the bottom of the cooking vessel with a cut protective sleeve.

Der Boden i -des Kochgefäßes ist nur auf der Außenseite mit spiralförmig verlaufenden Rillen 2 versehen, in welche die an die Stromzuführung 3 angeschlossene Heizspirale q. eingelegt und mittels eines leicht entfernbaren Kittes eingebettet ist. Die Rillen verlaufen über -den ganzen Boden des Gefäßes 5, wodurch die von (dem Heizkörper erzeugte Wärme in vollkommen gleichmäßiger Verteilung zur Wirkung gebracht. wird.The bottom of the cooking vessel is only spiral-shaped on the outside extending grooves 2, in which the connected to the power supply 3 Heating coil q. inserted and embedded using an easily removable putty is. The grooves run over the entire bottom of the vessel 5, whereby the of (The heat generated by the radiator in a perfectly even distribution to take effect brought. will.
