Depending on the setting, only one flame ring or the other flame ring or both flame rings is switched on or off at the same time.
- Gas cookers have the advantage that their heat is quickly available when switched on. However, they have the disadvantage that the gas flames cannot be made arbitrarily small, but that the flame goes out when the amount of gas supplied falls below a certain minimum. As a result, the smallest adjustable gas heating output is limited to a value at which the gas flames are small but do not go out.
- gas burners and gas actuators are designed for the reliable, lowest burner output. As a guideline for the lowest burner output, depending on the type of gas, approximately 1/6 of the nominal output of the gas burner applies. This means that the smallest possible adjustable gas heating capacity depends on the maximum possible gas heating capacity of the burner. It has also been proposed to supply the gas burner with pulsating gas by means of an electronic control in combination with solenoid valves, so that the gas flames are switched on and off in a pulsating manner.

This value is 17% very high compared to electrical heating devices in which a minimum electrical heating power down to only 6% of the maximum electrical heating capacity, with electronic control even only 3% of the maximum electrical heating capacity.
- the gas heating output which can be set as small as possible is too high for gas burners for many cooking processes for cooking food, for example for finishing small amounts of food, for melting butter, for keeping food warm and the like.
- a cooking appliance can be, for example, a cooker, a hob with one or more gas burners or a hotplate with one or more hotplates, each of which is provided with at least one gas burner.

- a cooking appliance according to the invention is characterized in that the at least one hotplate has, in addition to the gas heating device, an electric heating device with at least one electric heating element, the heating power of which is between a minimum electric heating power and a maximum
- Electric heating power is adjustable, and that the minimum electric heating power is less than the minimum gas heating power.
- the invention enables a cooking appliance which has a hotplate with a gas heating device to be reduced without expensive and complicated constructions.
- the heating output is reduced as far as is possible with electric cooking appliances, ie up to about 3% of the maximum adjustable heating output.
- the invention can also be used for cooking appliances with very large gas burners, e.g. B. so-called wok burners.
- very large gas burners e.g. B. so-called wok burners.
- the advantage of the invention is particularly noticeable when the cooking appliance has only a single hotplate.
- a pan support with integrated electric tubular heater covers the main performance range.
- the electric tubular heater preferably has direct contact with the bottom of a pot that can be placed on the hob.
- the electric tubular heater can be switched on manually from the minimum setting of the gas heating output range. This turns the gas burner into an electric hob.
- the heating power can be set and regulated in a known manner by energy regulators both when operating as a gas combustion station and when operating as an electric hob.
- a gas burner with an integrated electric tubular heater Burners are particularly suitable for this purpose, which are simultaneously designed as pan supports.
- the tubular heater can be integrated in the gas burner or attached to it.

Description
Kochqerät Kochqerät
Die Erfindung betrifft ein Kochgerät gemäß dem Oberbegriff von Anspruch 1.The invention relates to a cooking appliance according to the preamble of claim 1.
Demgemäß betrifft die Erfindung ein Kochgerät, enthaltend mindestens eine Kochstelle mit einer Gasheizvorrichtung, die mindestens einen Gasbrenner aufweist, dessen Heizleistung zwischen einer minimalen Gasheizleistung und einer maximalen Gasheizleistung einstellbar ist.Accordingly, the invention relates to a cooking appliance containing at least one hotplate with a gas heating device which has at least one gas burner, the heating output of which can be set between a minimum gas heating output and a maximum gas heating output.
Aus der EP-A-0 485 645 ist ein Gasbrenner für ein solches Kochgerät bekannt, welcher zwei koaxial ineinander angeordnete Flammenringe aufweist, welche wahlweise einzeln oder zusammen mit Gas versorgbar sind, um den Gasbrenner zwischen einer minimalen und einer maximalen Gasheizleistung einstellen zu können. Je nach Einstellung ist nur der eine Flammenring oder der andere Flammenring oder beide Flammenringe gleichzeitig eingeschaltet oder ausgeschaltet.From EP-A-0 485 645 a gas burner for such a cooking device is known which has two coaxially arranged flame rings which can be supplied individually or together with gas in order to be able to set the gas burner between a minimum and a maximum gas heating output. Depending on the setting, only one flame ring or the other flame ring or both flame rings is switched on or off at the same time.
Gaskochgeräte haben den Vorteil, daß ihre Hitze beim Einschalten schnell zur Verfügung steht. Sie haben aber den Nachteil, daß die Gasflammen nicht beliebig klein gemacht werden können, sondern daß bei Unterschreiten einer bestimmten Mindestmenge an zugeführtem Gas die Flamme ausgeht. Dadurch ist die kleinste einstellbare Gasheizleistung auf einen Wert begrenzt, bei welchem die Gasflammen zwar klein sind, aber gerade nicht ausgehen. Gasbrenner und Gas-Stellglieder werden aus technischen Gründen auf die zuverlässige, kleinste Brennerleistung ausgelegt. Als Richtwert für die kleinste Brennerleistung gilt je nach Gasart ungefähr 1/6 der Nennleistung des Gasbrenners. Dies bedeutet, daß die kleinstmögliche einstellbare Gasheizleistung von der maximal möglichen Gasheizleistung des Brenners abhängig ist. Es wurde auch bereits vorgeschlagen, durch eine elektronische Steuerung in Kombination mit Magnetventilen den Gasbrenner pulsierend mit Gas zu versorgen, so daß die Gasflammen pulsierend eingeschaltet und ausgeschaltet werden.Gas cookers have the advantage that their heat is quickly available when switched on. However, they have the disadvantage that the gas flames cannot be made arbitrarily small, but that the flame goes out when the amount of gas supplied falls below a certain minimum. As a result, the smallest adjustable gas heating output is limited to a value at which the gas flames are small but do not go out. For technical reasons, gas burners and gas actuators are designed for the reliable, lowest burner output. As a guideline for the lowest burner output, depending on the type of gas, approximately 1/6 of the nominal output of the gas burner applies. This means that the smallest possible adjustable gas heating capacity depends on the maximum possible gas heating capacity of the burner. It has also been proposed to supply the gas burner with pulsating gas by means of an electronic control in combination with solenoid valves, so that the gas flames are switched on and off in a pulsating manner.
Die kleinstmöglich einstellbare Gasheizleistung von ungefähr 1/6 bedeutet, daß sie 17 % der maximal einstellbaren Gasheizleistung beträgt. Dieser Wert von 17 % ist
sehr hoch verglichen mit elektrischen Heizvorrichtungen, bei denen eine minimale Elektroheizleistung bis herunter auf nur 6% der maximalen Elektroheizleistung, bei elektronischer Regelung sogar nur 3% der maximalen Elektroheizleistung beträgt.The smallest possible gas heating capacity of approximately 1/6 means that it is 17% of the maximum adjustable gas heating capacity. This value is 17% very high compared to electrical heating devices in which a minimum electrical heating power down to only 6% of the maximum electrical heating capacity, with electronic control even only 3% of the maximum electrical heating capacity.
Deshalb ist bei Gasbrennern die kleinstmöglich einstellbare Gasheizleistung zu hoch für viele Garvorgänge zum Garen von Nahrungsmitteln, beispielsweise zum Fertiggaren von kleinen Nahrungsmittelmengen, zum Schmelzen von Butter, zum Warmhalten von Speisen und dergleichen.For this reason, the gas heating output which can be set as small as possible is too high for gas burners for many cooking processes for cooking food, for example for finishing small amounts of food, for melting butter, for keeping food warm and the like.
Bekannte Ausführungen von Gaskochgeräten mit Gasbrennern, welche 1 , 2 oder 3Known versions of gas cooking devices with gas burners, which 1, 2 or 3
Flammenkreise haben, verursachen hohe Kosten in der Herstellung und ermöglichen trotzdem nicht eine ausreichende Kleinstellung der Gasheizleistung.Flame circles have high manufacturing costs and still do not allow the gas heating output to be set sufficiently low.
Ein Kochgerät kann beispielsweise ein Kochherd, eine Kochmulde mit einer oder mehreren Gasbrennern oder eine Kochplatte mit einer oder mehreren Kochstellen sein, von welchen jede Kochstelle mit mindestens einem Gasbrenner versehen ist. Die Geräte können einzeln aufstellbare Geräte oder Einbaugeräte sein.A cooking appliance can be, for example, a cooker, a hob with one or more gas burners or a hotplate with one or more hotplates, each of which is provided with at least one gas burner. The devices can be stand-alone devices or built-in devices.
Durch die Erfindung soll die Aufgabe gelöst werden, auf konstruktiv einfache und auf preiswerte Weise ein Kochgerät zu schaffen, welches die Vorteile einer Gasheizvorrichtung hat und auf eine wesentlich kleinere Heizleistung einstellbar ist als bekannte Gas-Kochgeräte.The object of the invention is to provide a cooking appliance which is structurally simple and inexpensive and which has the advantages of a gas heating device and can be set to a significantly lower heating output than known gas cooking appliances.
Diese Aufgabe wird gemäß der Erfindung durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.This object is achieved according to the invention by the characterizing features of claim 1.
Hierzu ist ein Kochgerät gemäß der Erfindung dadurch gekennzeichnet, dass die mindestens eine Kochstelle zusätzlich zu der Gasheizvorrichtung eine elektrische Heizvorrichtung mit mindestens einem elektrischen Heizkörper aufweist, deren Heizleistung zwischen einer minimale Elektroheizleistung und einer maximalenFor this purpose, a cooking appliance according to the invention is characterized in that the at least one hotplate has, in addition to the gas heating device, an electric heating device with at least one electric heating element, the heating power of which is between a minimum electric heating power and a maximum
Elektroheizleistung einstellbar ist, und dass die minimale Elektroheizleistung kleiner als die minimale Gasheizleistung ist.Electric heating power is adjustable, and that the minimum electric heating power is less than the minimum gas heating power.
Die Erfindung ermöglicht ohne teuere und komplizierte Konstruktionen bei einem Kochgerät, welches eine Kochstelle mit einer Gasheizvorrichtung hat, eine Redu-
zierung der Heizleistung soweit herunter, wie dies bei Elektro-Kochgeräten möglich ist, d. h. bis auf etwa 3 % der maximal einstellbaren Heizleistung.The invention enables a cooking appliance which has a hotplate with a gas heating device to be reduced without expensive and complicated constructions. The heating output is reduced as far as is possible with electric cooking appliances, ie up to about 3% of the maximum adjustable heating output.
Die Erfindung ist auch für Kochgeräte mit sehr großen Gasbrennern verwendbar, z. B. sogenannten Wok-Brennern. Der Vorteil der Erfindung macht sich insbesondere dann bemerkbar, wenn das Kochgerät nur eine einzige Kochstelle hat.The invention can also be used for cooking appliances with very large gas burners, e.g. B. so-called wok burners. The advantage of the invention is particularly noticeable when the cooking appliance has only a single hotplate.

A vessel which can be placed on the hotplate is thus mainly carried by the pot support 24, while the contacting of the bottom of the vessel with the electric heater 16 is only for Heat transfer to the pot is used
Gemäß einer abgewandelten Ausfuhrungsform ist der elektrische Heizkörper 16 in den Topftrager 24 integriertAccording to a modified embodiment, the electric heater 16 is integrated in the pot support 24
An dem Bedienelement 12 ist nicht nur die Gasheizleistung des Gasbrenners 8, sondern auch die elektrische Heizleistung des elektrischen Heizkörpers 16 ma- nuell einstellbar Das Bedienelement 12 hat einen an der Bedienblende 26 markierten Gaseinstellbereich I für die Gasheizvornchtung 6 mit deren Gasbrenner 8 und einen Elektroeinstellbereich II für die elektrische Heizvorrichtung 14 mit deren elektrischem Heizkörper 16 Die beiden Einstellbereiche I und II sind auf einem definierten Bewegungsweg einer Spitze 28 des Einstellelementes 12 nach- einander angeordnet Die niedrigste Gasheizleistung ist der höchsten Elektroheizleistung benachbart Beide grenzen an der mit "1/6" bezeichneten Stelle aneinander an und mit dem Bedienelement 12 ist wahlweise von der niedrigsten Gasheizleistung auf die höchste Elektroheizleistung umschaltbar an der mit "1/6" bezeichneten Stelle Die einstellbare höchste Gasheizleistung ist am anderen Ende des Gaseinstellbereiches I mit "1/1" bezeichnet Die niedrigste Elektroheizleistung ist am anderen Ende des Elektroeinstellbereiches II mit "6/100" bezeichnetNot only the gas heating power of the gas burner 8, but also the electrical heating power of the electric radiator 16 can be manually adjusted on the operating element 12. The operating element 12 has a gas setting area I marked on the operating panel 26 for the gas heating device 6 with its gas burner 8 and an electrical setting area II for the electric heating device 14 with its electric heating element 16 The two setting ranges I and II are arranged one after the other on a defined path of movement of a tip 28 of the setting element 12. The lowest gas heating power is adjacent to the highest electric heating power. Both border on the one marked "1/6" Place on each other and with the control element 12 is optionally switchable from the lowest gas heating output to the highest electrical heating output at the point labeled "1/6".

Fig 4 zeigt ein Diagram, in welchem auf der horizontalen Achse die Drehwinkel "α" aufgetragen sind, auf welche das Einstellelement 12 einstellbar ist Auf der vertikalen Achse des Diagrams ist die Heizleistung "P" aufgetragen Auf der horizontalen Achse ist der Drehwinkeibereich auf den ersten Einstellbereich I der Gasheizleistung und auf den zweiten Einstellbereich II der Elektroheizleistung aufgeteilt Zum Zünden des Gasbrenners 8 wird er am Einstellelement 12 auf
höchste Heizleistung "1/1 " eingestellt und sein ausströmendes Gas wird automatisch oder manuell gezündet, je nach Ausführungsform des Kochgerätes, wobei eine automatische Zündeinrichtung die bevorzugte Ausführungsform ist. Wenn die Gasheizleistung am Bedienelement 12 über den kleinsten, vorbe- stimmten Einstellwert von beispielsweise "1/6" des Maximalwertes "1/1 " reduziert wird, wird an dieser Stelle automatisch die Gaszufuhr zum Gasbrenner 8 unterbrochen und stattdessen der elektrische Heizkörper 16 eingeschaltet, und zwar auf seinen höchsten Elektroheizleistungswert. Von diesem kann er am Bedienelement 12 reduziert werden bis auf einen vorbestimmten kleinsten Elektro- heizleistungswert von z. B. "6/100". Wenn die Heizleistung weiter reduziert wird, wird das Gerät an dem manuellen Bedienelement 12 automatisch abgeschaltet. Der Leistungsbereich kann selbstverständlich auch von dem minimalsten Elektroheizleistungswert bis zum maximalen Gasheizleistungswert durchfahren werden. In diesem Falle erfolgt die Zündung des aus dem Gasbrenner 8 ausströ- menden Gases nicht erst bei der Einstellung des maximalen Gasheizleistungswertes "1/1 ", sondern selbstverständlich beim Übergang vom Elektroheizbetrieb auf den Gasbetrieb, wenn die Einstellung der kleinstmöglichen Gasheizleistung von z. B. "1/6" des Maximalheizleistungswertes "1/1" erreicht oder überschritten wird.4 shows a diagram in which the rotation angle "α" is plotted on the horizontal axis, to which the setting element 12 can be adjusted. The heating power "P" is plotted on the vertical axis of the diagram. The rotation angle range is at first on the horizontal axis Setting range I of the gas heating power and divided into the second setting range II of the electric heating power. To ignite the gas burner 8, it is set on the setting element 12 highest heating output is set to "1/1" and its outflowing gas is ignited automatically or manually, depending on the embodiment of the cooking appliance, an automatic ignition device being the preferred embodiment. If the gas heating power on the control element 12 is reduced above the smallest, predetermined setting value of, for example, “1/6” of the maximum value “1/1”, the gas supply to the gas burner 8 is automatically interrupted at this point and the electric heater 16 is switched on instead, and that to its highest electrical heating output value. From this, it can be reduced on the control element 12 to a predetermined minimum electrical heating power value of z. B. "6/100". If the heating power is further reduced, the device on the manual control element 12 is automatically switched off. The performance range can of course also be covered from the minimum electrical heating output value to the maximum gas heating output value. In this case, the ignition of the gas flowing out of the gas burner 8 does not take place only when the maximum gas heating power value is set to “1/1”, but of course during the transition from electric heating mode to gas mode if the setting of the smallest possible gas heating power of z. B. "1/6" of the maximum heating output value "1/1" is reached or exceeded.
Gemäß einer besonderen Ausführungsform kann für eine Schnellkochstelle eine Einstellmöglichkeit vorgesehen sein, um den Brenner 8 der Gasheizvorrichtung 6 und den elektrischen Heizkörper 16 der elektrischen Heizvorrichtung 14 gleichzeitig einzuschalten, um eine Heizleistung zu erzeugen, die größer ist als die höchste Heizleistung der Gasheizvorrichtung. Eine solche Einstellmöglichkeit kann beispielsweise dadurch gegeben sein, daß das Einstellelement 12 einen dritten Drehbereich hierfür hat oder axial verstellbar ist, um diese Einstellung vorzunehmen.According to a particular embodiment, an adjustment option can be provided for a rapid cooking zone in order to simultaneously switch on the burner 8 of the gas heating device 6 and the electric heating element 16 of the electric heating device 14 in order to generate a heating power which is greater than the highest heating power of the gas heating device.

Topfträger 24-2 ein Gasbrenner 8 mit einem oder mehreren Kränzen von Gasauslaßöffnungen 10 und mindestens ein elektrischer Heizkörper 16 integriert sind. Stattdessen kann der Heizkörper 16 an dem Topfträger 24-2 auch befestigt statt integriert sein. In beiden Fällen bilden die Gasheizvorrichtung 6 mit dem
Gasbrenner 8 und die elektrische Heizvorrichtung 14 mit dem elektrischen Heizkörper 16 zusammen mit dem Topfträger 24-2 eine Baueinheit.Pot support 24-2, a gas burner 8 with one or more rings of gas outlet openings 10 and at least one electric heating element 16 are integrated. Instead, the radiator 16 can also be attached to the pot support 24-2 instead of integrated. In both cases, the gas heating device 6 forms with the Gas burner 8 and the electric heater 14 with the electric heater 16 together with the pot support 24-2 a structural unit.
Die Fig. 7 und 8 zeigen eine weitere Ausführungsform der Erfindung, bei welcher der mindestens eine elektrische Heizkörper 16 in einen Topfträger 24 integriert ist und einen Gasbrenner 8 der Gasheizvorrichtung 6 in gleichbleibendem Abstand umgibt. Die elektrische Heizleistung und die Gasheizleistung können wie bei den anderen Ausführungsformen durch das gleiche Bedienelement 12 einstellbar sein oder, wie dies in den Fig. 7 und 8 dargestellt, durch ein Einstell- element 12-1 für die Gasheizvorrichtung 6 und ein weiteres Einstellelement 12-2 für die elektrische Heizvorrichtung 14.7 and 8 show a further embodiment of the invention, in which the at least one electric heating element 16 is integrated in a pot support 24 and surrounds a gas burner 8 of the gas heating device 6 at a constant distance. As in the other embodiments, the electrical heating power and the gas heating power can be adjustable by the same control element 12 or, as shown in FIGS. 7 and 8, by an adjusting element 12-1 for the gas heating device 6 and a further adjusting element 12- 2 for the electric heating device 14.
Gemäß den bevorzugten Ausführungsformen kontaktiert der elektrische Heizkörper 16 den Boden oder eine Seitenwand eines auf ihn stellbaren Gefäßes, z. B. Topfes oder Pfanne. Gemäß anderer Ausführungsform kann zwischen dem Heizkörper 16 und dem Gefäß auch ein Abstand vorhanden sein, was jedoch die Wärmetransfergeschwindigkeit beeinträchtigt.
According to the preferred embodiments, the electric heater 16 contacts the bottom or a side wall of a vessel that can be placed on it, e.g. B. pot or pan. According to another embodiment, there may also be a distance between the radiator 16 and the vessel, but this affects the rate of heat transfer.
