Description

Vorrichtung zum Erhitzen von wasserhaltigen Feststoffen, vorzugsweise Lebensmitteln Die Erfindung betrifft eine Vorrichtung zum Erhitzen von wasserhaltigen Feststoffen, vorzugsweise von Lebensmitteln, bei der in einem topfartigen Gefäß die Feststoffe als stromleitende Verbindung zwischen spannungsführende Elektroden eingebracht werden und der Kontakt zwischen den Elektroden und den Feststoffen durch eine Wasserfüllung hergestellt wird. Bekannte Vorrichtungen dieser Art eignen sich nicht ohne weiteres zur Elektrodenerhitzung von kleinstückigen, unregelmäßig geformten Lebensmitteln wie Kartoffeln, Gemüse u. dgl. Bei solcher Art von Lebensmitteln kommt es darauf an, diese vor einer unmittelbaren Berührung mit den Elektroden zu schützen. Andererseits soll durch die Erfindung erreicht werden, daß beim Erhitzen solcher Feststoffe durch Verkochen der Wasserfüllung im Behälter der Elektrodenstrom zum Abreißen gebracht wird.Device for heating water-containing solids, preferably The invention relates to a device for heating water-containing food Solids, preferably food, in a pot-like container the solids as a current-conducting connection between voltage-carrying electrodes are introduced and the contact between the electrodes and the solids through a water filling is made. Known devices of this type are suitable not easily used for heating up small, irregularly shaped electrodes Foods such as potatoes, vegetables, and the like. This type of food comes with it it is important to protect them from direct contact with the electrodes. On the other hand, should be achieved by the invention that when heated such Solids by boiling the water filling in the container to the electrode current Demolition is brought.

Die Vorrichtung ist erfindungsgemäß so ausgebildet, daß der Boden des Gefäßes zwischen den Elektroden nach oben eingezogen ist und daß auf dem eingezogenen Teil des Bodens, der unterhalb des Spiegels der Wasserfüllung liegt, ein aus Isolierstoff bestehender siebartiger Behälter zur Aufnahme der Feststoffe aufliegt. Die zu erhitzenden Lebensmittel sind dann von den Elektroden vollständig getrennt in einem siebartigen Behälter untergebracht. Sie können nach dem Erhitzen geschlossen aus der Vorrichtung herausgenommen werden. Beim Sinken des Wasserspiegels unter den eingezogenen Gehäuseboden hört der Stromfluß selbsttätig auf.According to the invention, the device is designed so that the floor of the vessel is drawn up between the electrodes and that on the drawn in Part of the bottom, which is below the level of the water filling, is made of insulating material existing sieve-like container for receiving the solids rests. The ones to be heated Food is then completely separated from the electrodes in a sieve-like manner Containers housed. They can be closed out of the device after heating be taken out. When the water level drops below the retracted case back the current flow stops automatically.

Ein Ausführungsbeispiel der Erfindung ist in der Abbildung schematisch dargestellt.An embodiment of the invention is shown schematically in the figure shown.

In einem aus Isolierstoff bestehenden topfförmigen Gefäß 1 sind auf beiden Seiten winklig gebogene Metallelektroden 2, 3 untergebracht und mit außen liegenden Stromzuführungstcilen 4, 5 leitend verbunden. Zwischen den Elektroden 2, 3 ist der Boden 6 des Gefäßes 1 nach innen eingezogen, so daß die Elektroden in Vertiefungen 7, 8 des Gefäßes 1 liegen. Auf dem eingezogenen Gefäßboden 6 liegt ein aus Isolierstoff bestehender Siebbehälter 9 auf, der zur Aufnahme des zu erhitzenden Gutes 10 (z. B. Kartoffeln) dient. Das Gefäß 1 wird mit Wasser gefüllt, so daß der Wasserspiegel 11 das Kochgut 10 bedeckt. Wird eine Wechselspannung an die Elektroden 2, 3 gelegt, dann fließt ein Elektrodenstrom durch das Kochgut 10, das als elektrischer Widerstand wirkt und sich infolgedessen durch Stromwärme schnell erhitzt. Durch die Wasserfüllung wird der Kontakt zwischen den Elektroden 2, 3 und dem Kochgut 10 hergestellt. Dieser Kontakt wird unterbrochen, sobald der Wasserspiegel 11 bis in Höhe des Behälterbodens 6 absinkt.In a pot-shaped vessel 1 made of insulating material, metal electrodes 2, 3 bent at an angle are accommodated on both sides and conductively connected to external power supply elements 4, 5. The bottom 6 of the vessel 1 is drawn inward between the electrodes 2, 3, so that the electrodes lie in depressions 7, 8 of the vessel 1. A sieve container 9 made of insulating material rests on the retracted vessel bottom 6 and serves to receive the goods 10 to be heated (e.g. potatoes). The vessel 1 is filled with water so that the water level 11 covers the food 10. If an alternating voltage is applied to the electrodes 2, 3, an electrode current flows through the food 10, which acts as an electrical resistance and as a result is quickly heated by the heat of the current. The contact between the electrodes 2, 3 and the food 10 to be cooked is established by the water filling. This contact is interrupted as soon as the water level 11 drops to the level of the container bottom 6.
