Description

Die Erfindung bezieht sich auf eine wahlweise elektrisch oder mit Gas beheizbare Kochstelle für ein Kochgerät od.dgl. mit einem im Zentrum eines ringförmig ausgebildeten elektrisch beheizten Kochkörpers angeordneten Gasbrenner.The invention relates to an optionally electrically or gas-heated hotplate for a cooking device or the like. with a gas burner arranged in the center of a ring-shaped, electrically heated cooking body.

Es ist allgemein bekannt, daß in der Ankochphase eine verhältnismäßig hohe Leistung dem Gargut zugeführt werden muß. Weiterhin ist es bekannt, daß gerade während der Ankochphase die Wärmeübertragung bei einer elektrischen Kochstelle im Gegensatz zu einer mit Gas beheizten Kochstelle in starkem Maße von der Qualität des Gargefäßes abhängig ist. Darüber hinaus läßt sich eine mit Gas beheizte Kochstelle, im Gegensatz zu einer elektrischen Kochstelle, in der Fortkochphase, bei der dem Gargut nur noch kleinere Heizleistungen zugeführt werden müssen, nur äußerst.mangelhaft auf kleinere Leistungen einregeln. Aus der DE-A 21 27 104 ist nun eine Kochstelle der eingangs genannten Art bekännt, bei der der elektrisch beheizte Kochkörper aus einer ringförmigen Gußplatte besteht, durch deren Zentrum der Gabrenner während seiner Betriebsstellung herausragt. Um den richtigen Abstand des Gasbrenners zum Boden des Kochgefäßes zu erhalten, ist es hier erforderlich, der Kochstelle eine gitterartige Kochgefäß-Tragvorrichtung zuz.pordnen.Weiterhin ist es erforderlich, damit beim Benützen des elektrischen Kochkörpers das Kochgefäß mit diesem in guten Wärmekontakt kommen kann, den Gasbrenner in Höhenrichtung absenkbar zu haltern. Für diese Art Kochstelle ist der konstruktive Aufwand jedoch beträchtlich. Auch ist bei dieser bekannten kombinierten Kochstelle kein reibungsloser Übergang von Ankochen mit Gas auf Fortkochen mit Elektroenergie möglich, da hier während des Kochens mit Gas das Kochgefäß auf einer besonderen Kochgefäß-Tragvorrichtung abgestellt ist, die keinen Kontakt des Kochgefäß-Bodens mit dem elektrisch beheizten Kochkörper zuläßt.It is generally known that a relatively high output must be supplied to the food to be cooked in the parboiling phase. Furthermore, it is known that especially during the boiling phase, the heat transfer in an electric hotplate, in contrast to a gas-heated hotplate, depends to a large extent on the quality of the cooking vessel. In addition, in contrast to an electric hob, a gas-heated hob can only be extremely poorly adjusted to smaller outputs in the continued cooking phase, in which only smaller heating outputs have to be added to the food. From DE-A 21 27 104 a hotplate of the type mentioned is now known, in which the electrically heated cooking body consists of an annular cast plate, through the center of which the Gabrenner protrudes during its operating position. In order to maintain the correct distance between the gas burner and the bottom of the cooking vessel, it is necessary to place a grille-like one in the hotplate Zuz cooking vessel carrying device. P ordnen.Weiterhin it is necessary for the cooking vessel can come up with this in good thermal contact with the use of the electric cooking body to hold the gas burner in the vertical direction can be lowered. The design effort for this type of hob is considerable. Also, with this known combined hotplate, a smooth transition from parboiling with gas to continued boiling with electrical energy is not possible, since during the cooking with gas the cooking vessel is placed on a special cooking vessel carrying device that does not contact the bottom of the cooking vessel with the electrically heated cooking body allows.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, die Kochstelle der eingangs genannten Art baulich weiter zu vereinfachen.The invention seeks to remedy this. The invention, as characterized in the claims, solves the task of structurally further simplifying the hotplate of the type mentioned.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, daß eine kombinierte Kochstelle geschaffen wird, die in der Handhabung bzw. Bedienung denkbar einfach ist und die bei einem Kochvorgang eine optimale Ausnutzung der Vorteile des Ankochens mit Gas und des Fortkochens mit niedere und leicht zu regelnder Elektroenergie gestattet. Da das Kochgefäß mit seinem Boden hier ständig in unmittelbaren Kontakt mit dem elektrischen Kochkörper gebracht ist, entfällt ein manuelles Umrüsten dieser Kochstelle nach Beendigung der Ankochphase mit Gas. Es kann hier somit ohne weiteres Zutun von Gas auf Elektroenergie umgeschaltet werden, ohne daß an der Kochstelle selbst Eingriffe bzw. Umstellungen vorgenommen werden müssen.The advantages achieved by the invention are essentially to be seen in the fact that a combined hotplate is created, which is very easy to use and operate and which makes optimal use of the advantages of parboiling with gas and continued boiling with low and easily regulated electrical energy allowed. Since the bottom of the cooking vessel is constantly brought into direct contact with the electric cooking body, there is no need to manually retrofit this hotplate with gas after the cooking phase has ended. It is thus possible to switch from gas to electrical energy without further intervention, without having to make any changes or adjustments to the hob itself.

Mit 1 ist eine sogen. Kochmulde eines nicht weiter dargestellten Kochgerätes bezeichnet, in der eine Kochstelle 2 angeordnet ist. Die Kochstelle 2 besteht aus einem üblichen Gasbrenner 3 und einem über dem Gasbrenner befindlichen elektrischen Kochkörper 4, auf dem ein'Kochgefäß 5 abgestellt ist. Der Gasbrenner 3 ist im Zentrum des Kochmulden-Bodens 1' eingesetzt und entspricht in seiner Höhe in etwa der Tiefe der Kochmulde. Der elektrische Kochkörper 4 ist aus mehreren elektrischen Mantelrohrheizkörperteilen 6 bis 11 gebildet. Jedes der Mantelrohrheizkörperteile 6 bis 11 ist etwa schleifenförmig ausgebildet. Die einzelnen Schleifen 12,13 dieser Heizkörperteile, die sternförmig angeordnet sind, münden in einen Zentralverteiler 14, an dem sie feuchtigkeitsdicht befestigt und elektrisch in Reihe geschaltet sind. Die einzelnen Schleifen 12,13 sind dabei so ausgebildet, daß die obere Schleife 12, auf welcher das Kochgefäß 5 steht, eine elektrische Heizwendel 4' aufweist, während die untere Schleife 13 lediglich zur Rückführung 4" der elektrischen Heizwendel dient. Die schleifenförmigen Mantelrohrheizkörperteile 6,7,8,9 und 10 sind am Umkehrende 15 in Richtung zum Kochmuldenrand hin gebogen und finden in einer dort vorgesehenen umlaufenden Einprägung 16 eine Abstützung. Damit wird erreicht, daß der sternförmige elektrische Kochkörper 4 beim Betreiben der Kochstelle mit Gas gleichzeitig als Topfträger dienen kann. Das eine Mantelrohrheizkörperteil 11 ist durch die Muldenwandung 1" zur elektrischen Zuleitung geführt und ist dort mit einem schwenkbaren Dichtkörper 17 entsprechend abgedichtet. Zwecks Reinigung der Kochmulde 1 kann der elektrische Kochkörper 2 mittels des schwenkbaren Dichtkörpers 17 in bekannter Weise um ca. 90° hochgeklappt werden.With 1 is a so-called. Cooking hob of a cooking device, not shown, in which a hotplate 2 is arranged. The hotplate 2 consists of a conventional gas burner 3 and an electric cooking element 4 located above the gas burner, on which a cooking vessel 5 is placed. The gas burner 3 is inserted in the center of the hob bottom 1 'and its height corresponds approximately to the depth of the hob. The electric cooking element 4 is formed from a plurality of electrical jacket tube heating element parts 6 to 11. Each of the tubular casing heater parts 6 to 11 is approximately loop-shaped. The individual loops 12, 13 of these radiator parts, which are arranged in a star shape, open into a central distributor 14, to which they are attached in a moisture-tight manner and are electrically connected in series. The individual loops 12, 13 are designed in such a way that the upper loop 12, on which the cooking vessel 5 stands, has an electric heating coil 4 ', while the lower loop 13 is only used for returning 4 "of the electric heating coil. The loop-shaped tubular heating element parts 6 , 7, 8, 9 and 10 are bent at the reversing end 15 in the direction of the hob edge and are supported in a circumferential indentation 16 provided there, so that the star-shaped electric cooking body 4 also serves as a pan support when the gas hob is operated with gas The one tubular casing heater part 11 is led through the trough wall 1 "to the electrical supply line and is sealed there accordingly with a pivotable sealing body 17. In order to clean the hob 1, the electric cooking body 2 can be folded up by approximately 90 ° in a known manner by means of the pivotable sealing body 17.
