Description

Kocheinrichtungen mit elektrischer und Gasbeheizung sind bekannt. Sie verfolgen den Zweck, beim Versagen der einen Beheizungsart die andere verwenden zu können.Cooking devices with electric and gas heating are known. Their purpose is to use the other if one type of heating fails to be able to.

So ist z. B. in dem Gußkörper einer elektrischen Kochplatte eine Mittelöffnung vorgesehen, die den Gasbrenner aufnimmt. Die Heizfläche der elektrischen Kochplatte ist hierbei aber unter dem Tragrost des Gasherdes angeordnet. Würde man bei einer solchen Einrichtung beide Heizquellen gleichzeitig betreiben, so wäre infolge des geringen Wärmeüberganges über den Tragrost zum Kochgut eine wirtschaftliche Ausnutzung der in der elektrischen Kochplatte erzeugten Wärme nicht möglich. Praktisch können hierbei beide Wärmequellen also nicht gleichzeitig betrieben werden.So is z. B. a central opening in the cast body of an electric hotplate provided that houses the gas burner. The heating surface of the electric hotplate but is arranged under the support grate of the gas range. You would with a such a device operate both heat sources at the same time, so would be as a result of low heat transfer via the support grid to the food, an economical use the heat generated in the electric hotplate is not possible. Practically can in this case both heat sources are not operated at the same time.

Um diese Nachteile der. bekannten Anordnung zu vermeiden, wird eine Kocheinrichtung mit elektrischer und Gasbeheizung, bei .der dem Gasbrenner ein elektrisches Heizelement zugeordnet ist, erfindungsgemäß so ausgebildet, daß das elektrische Heizelement aus einem oder mehreren vorzugsweise wärmestrahlenden Rohrheizkörpern gebildet ist, die in unmittelbarem Wärmekontakt mit dem Kochgut stehen und der Gasflamnie den Zutritt zu diesen' frei lassen. Die Tragstege des Gasherdes dienen hierbei als Auflager für das leicht auswechselbare elektrische Heizelement, während dieses den Tragrost für das Kochgut bildet. Durch die Verwendung von hitzebeständigen, hochbelastbaren Rohrheizkörpern wird für den elektrischen Teil der Heizung nur wenig Raum benötigt und der Zutritt der Gasflamme zum Kochgut in keiner Weise behindert. Ferner werden infolge der geringen Speichermasse der Rohrheizkörper Wärmeverluste vermieden. Die immer wieder gestellte Forderung nach Verkürzung der Ankochzeiten läßt sich mit der erfindungsgemäßen Anordnung in hohem Maße verwirklichen, da beide Heizquellen ohne gegenseitige Beeinträchtigung voll ausgenutzt werden können. Ein weiterer Vorteil der Erfindung ist die auch bei gleichzeitigem Betrieb beider Heizquellen mögliche stufenlose Regelbarkeit, die bisher nur bei reiner Gasbeheizung verbreitete Anwendung finden konnte.To these disadvantages of the. to avoid known arrangement is a Cooking device with electric and gas heating, with the gas burner an electric one Heating element is assigned, according to the invention designed so that the electrical Heating element made up of one or more tubular heating elements, preferably radiating heat is formed, which are in direct thermal contact with the food and the gas flame leave free access to these '. The support bars of the gas range serve as a Support for the easily replaceable electrical heating element, during this the Forms support grid for the food. By using heat-resistant, heavy-duty Tubular heaters only need a little space for the electrical part of the heating and the access of the gas flame to the food is not hindered in any way. Furthermore will due to the low storage mass of the tubular heating element, heat losses are avoided. the repeatedly asked demand for shortening the boiling times can be with Realize the arrangement according to the invention to a large extent, since both heat sources can be fully exploited without adversely affecting each other. Another advantage the invention is also possible with simultaneous operation of both heating sources Infinitely variable control, the application that was previously only widespread with gas-only heating could find.

Eine der gemäß der Erfindung möglichen Ausführungsformen ist in der Abb. i im Schnitt und in Abb.2 im Grundriß dargestellt.One of the possible embodiments according to the invention is shown in FIG Fig. I is shown in section and in Fig. 2 in plan.

Der Rahmen i des Herdes trägt den Gasbrenner 2 mit dem Gashahn 3 sowie das auf den Tragstegen aufliegende, leicht auswechselbare elektrische Heizelement 5 mit seinem Regelschalter 6. Beim Versagen der Gaszufuhr kann natürlich die elektrische Heizung allein betrieben werden, wie beim Ausbleiben des Stromes auch nur die Gasheizung benutzt werden kann.The frame i of the stove carries the gas burner 2 with the gas tap 3 as well the easily replaceable electrical heating element resting on the support webs 5 with its control switch 6. If the gas supply fails, of course, the electrical Heating can be operated alone, as if there is no electricity, only gas heating can be used.
