Description

Die Erfindung betrifft ein Kochgerät für eine Wok-Pfanne mit einer der Form der Wok-Pfanne angepaßten Halterung und einer Heizeinrichtung.The invention relates to a cooking device for a wok pan with a holder adapted to the shape of the wok pan and a heating device.

Die Wok-Pfanne als herkömmliches Kochgefäß der asiatischen Küche wird auch in der westlichen Welt zunehmend angewendet. Sie besteht aus einem halbkugeligen Topf aus Metall mit angearbeitetem Griffstiel. In den Ursprungsländern erfolgt bis in die heutige Zeit die Erhitzung über offenem Feuer. In modernen Küchen kommt als Wärmequelle nur eine Gaskochstelle in Frage, um die Wok-Pfanne von unten mit der Gasflamme zu erhitzen. Hierzu sind auch geeignete Halterungen entwickelt worden, um die Wok-Pfanne über der Gasflamme sicher absetzen zu können.The wok pan as a traditional cooking vessel in Asian cuisine is also increasingly used in the western world. It consists of a hemispherical pot made of metal with a handle attached. In the countries of origin, heating is still carried out over an open fire. In modern kitchens, the only possible heat source is a gas hob to heat the wok pan from below with the gas flame. Suitable brackets have also been developed for this so that the wok pan can be safely placed over the gas flame.

Auf üblichen Elektroherden kann eine Wok-Pfanne dagegen nicht erhitzt werden, weil die ebenen Kochplatten bzw. Kochfelder in Flächenkontakt mit dem Boden des Kochgefäßes sein müssen. Zum elektrischen Erhitzen einer Wok-Pfanne sind bislang nur fest angepreßte Elektroheizkörper mit angearbeitetem Standfuß und Schaltkasten bekannt geworden. Solche Geräte sind aber unhandlich und wegen des Wärmespeichervermögens der elektrischen Widerstandsheizung schwer zu regeln.In contrast, a wok pan cannot be heated on conventional electric stoves because the flat hotplates or hobs must be in surface contact with the bottom of the cooking vessel. So far, only firmly pressed electric radiators with attached base have been used for electrically heating a wok pan and switch box become known. Such devices are unwieldy and difficult to control because of the heat storage capacity of the electrical resistance heater.

Der Erfindung liegt die Aufgabe zugrunde, ein Kochgerät zu schaffen, mit dem eine Wok-Pfanne durch elektrische Energie in nahezu gleicher Weise wie durch eine Flamme erhitzt werden kann.The invention has for its object to provide a cooking device with which a wok pan can be heated by electrical energy in almost the same way as by a flame.

Zur Lösung der Aufgabe besteht die Halterung für die Wok-pfanne aus einer Küvette in Form einer nach oben offenen Kugelkalotte zur Aufnahme der Wok-Pfanne, und die Heizeinrichtung ist als elektrische Induktionsheizung ausgebildet.To achieve the object, the holder for the wok pan consists of a cuvette in the form of an upwardly open spherical cap for receiving the wok pan, and the heating device is designed as an electrical induction heater.

Die kugelkalottenförmige Küvette ist mit ihrer Innenfläche auf die Form der Wok-Pfanne abgestimmt, die damit so in die Küvette eingesetzt werden kann, daß einerseits die Induktionswärme verlustfrei in die Wok-Pfanne übertragen wird, andererseits die Wok-Pfanne sich noch bewegen läßt. Unterhalb der Küvette liegen um deren Wandung Induktionsspulen, die über einen Elektrogenerator versorgt werden. Das magnetische Induktionsfeld erhitzt in gleicher Weise wie ein Gasbrenner das eisenhaltige Material des Wok, so daß sich in der Zubereitung der Speisen kein Unterschied ergibt. Das Induktionsfeld kann ebenso wie eine Flamme abgeschaltet und in der Intensität geregelt werden, so daß auch insoweit kein Unterschied vorhanden ist.The spherical cap-shaped cuvette is matched with its inner surface to the shape of the wok pan, which can thus be inserted into the cuvette so that on the one hand the induction heat is transferred to the wok pan without loss, and on the other hand the wok pan can still be moved. There are induction coils around the wall below the cuvette, which are supplied by an electrical generator. The magnetic induction field heats the iron-containing material of the wok in the same way as a gas burner, so that there is no difference in the preparation of the dishes. Like a flame, the induction field can be switched off and the intensity can be regulated, so that there is no difference in this respect either.

Vorteilhafte Ausgestaltungen sind Gegenstand der Ansprüche 2 bis 20.Advantageous embodiments are the subject of claims 2 to 20.

Die Aufnahmeküvette besteht vorzugsweise aus Keramik oder Steingut, das für das magnetische Induktionsfeld gut durchlässig ist, ohne selbst davon erwärmt zu werden. Auch das für Herdplatten bekannte Glaskeramikmaterial ist für diesen Zweck geeignet.The receiving cuvette is preferably made of ceramic or earthenware, which is well permeable to the magnetic induction field without being heated by it itself. The glass ceramic material known for stovetops is also suitable for this purpose.

Die Küvette kann in ein Tisch- oder Einzelgerät eingebaut sein, dessen Gehäuse den Elektrogenerator für die Induktionsspule bzw. die Induktionsspulen aufnimmt. Dabei können auf der Oberseite des Gehäuses auch mehrere Küvetten angeordnet sein, um in zwei oder mehr Wok-Pfannen gleichzeitig kochen zu können und/oder mit Wok-Pfannen unterschiedlicher Form und Größe zu arbeiten.The cuvette can be installed in a table or single device, the housing of which accommodates the electrical generator for the induction coil or the induction coils. Several cuvettes can also be arranged on the top of the housing in order to be able to cook in two or more wok pans at the same time and / or to work with wok pans of different shape and size.

Eine andere Möglichkeit besteht darin, das Kochgerät in das Kochfeld eines Elektroherdes zu integrieren. Hierzu erhält die Herdoberfläche einen kreisförmigen Ausschnitt, in den fugendicht die Aufnahmeküvette für die Wok-Pfanne eingesetzt wird. Mit der Wok-Pfanne kann dann wie mit anderen Kochgefäßen auf dem Herd gearbeitet werden. Besonders geeignet sind dabei induktionsbeheizte Herde, die dieselbe Regeltechnik wie das erfindungsgemäße Kochgerät aufweisen.Another possibility is to integrate the cooking appliance into the hob of an electric cooker. For this purpose, the surface of the cooker is given a circular cutout in which the receiving cuvette for the wok pan is inserted in a sealed manner. The wok pan can then be used on the stove like other cooking vessels. Induction-heated cookers which have the same control technology as the cooking device according to the invention are particularly suitable.

Die Zeichnung zeigt als Beispiel ein erfindungsgemäßes Kochgerät im Schnitt.The drawing shows an example of a cooking device according to the invention in section.

Die Wok-Pfanne 1 bildet ein halbkugeliges Gefäß mit einem stielartigen Griff. Die Gefäßwandung besteht aus Eisen oder einem eisenhaltigen Material. Zur Aufnahme des Gefäßes dient eine Küvette 2 aus Keramikmaterial in Form einer Kugelkalotte, von der der Wok mit seinem unteren Teil aufgenommen wird. Die Küvette 2 ist in die Oberfläche eines Kochfeldes oder eines Tischgerätes in der dargestellten Weise eingepaßt.The wok pan 1 forms a hemispherical vessel with a handle-like handle. The vessel wall consists of iron or an iron-containing material. A cuvette 2 made of ceramic material in the form of a spherical cap serves to hold the vessel, the lower part of which holds the wok. The cuvette 2 is fitted into the surface of a hob or a table device in the manner shown.

Wie aus der Zeichnung ersichtlich, weisen die Außenfläche der Wok-Pfanne 1 und die Innenfläche der Küvette 3 nicht denselben Krümmungsradius auf, sondern die Küvette ist mit einem größeren Radius gekrümmt als die Küvette. Infolge dieser Größenverhältnisse läßt sich die Wok-Pfanne in der Küvette drehen und schwenken, um das darin befindliche Kochgut zu bewegen und zu mischen. Da die Energieübertragung induktiv erfolgt, ist eine vollständige flächige Anlage nicht erforderlich.As can be seen from the drawing, the outer surface of the wok pan 1 and the inner surface of the cuvette 3 do not have the same radius of curvature, but the cuvette is curved with a larger radius than the cuvette. As a result of these proportions, the wok pan can be rotated and swiveled in the cuvette in order to move and mix the items to be cooked therein. Since the energy transfer takes place inductively, a complete flat system is not necessary.

Das Verhältnis der Krümmungsradien muß so gewählt sein, daß die Wok-Pfanne 1 einerseits genügend beweglich ist, andererseits noch sicher in der Küvette 3 gehalten wird. Diese Forderung wird dadurch erfüllt, daß der Radius der Küvette um 3 bis 5% größer ist als der der Wok-Pfanne, d.h. die Radien errechnen sich nach folgender Gleichung:

Figure imgb0001

wobei R den Radius der Küvettenkugelkalotte und r den Radius der Wok-Pfannenkugelkalotte bezeichnet.The ratio of the radii of curvature must be selected so that the wok pan 1 is sufficiently mobile on the one hand, and on the other hand is still securely held in the cuvette 3. This requirement is met in that the radius of the cuvette is 3 to 5% larger than that of the wok pan, ie the radii are calculated using the following equation:
Figure imgb0001
where R denotes the radius of the cuvette spherical cap and r the radius of the wok pan spherical cap.

An der Unterseite der Küvette 2 befinden sich Induktionsspulen 4, die von einem Elektrogenerator 6 mit Energie versorgt werden. In dem dargestellten Ausführungsbeispiel sind zwei Lagen von Induktionsspulen 4 vorgesehen, von denen die untere Lage nur dem mittleren bzw. unteren Bereich der Wok-Pfanne Wärmeenergie zuführt, in dem sich das meiste Kochgut befindet. Derselbe Effekt läßt sich erreichen, wenn anstelle der zweiten Lage oder auch zusätzlich dazu die unmittelbar an der Unterseite der Küvette anliegende Induktionsspule in der Weise spiralförmig verläuft, daß die Windungen in der Mitte dichter aneinanderliegen als in den Außenbereichen.On the underside of the cuvette 2 there are induction coils 4, which are supplied with energy by an electric generator 6. In the exemplary embodiment shown, two layers of induction coils 4 are provided, of which the lower layer supplies thermal energy only to the middle or lower region of the wok pan, in which most of the cooking material is located. The same effect can be achieved if, instead of or in addition to the second layer, the induction coil lying directly on the underside of the cuvette runs in a spiral shape in such a way that the turns are closer to one another in the middle than in the outer areas.

Die Induktionsspule bzw. Induktionsspulen sind mit einem aushärtbaren, temperaturresistenten Zweikomponentenkleber an der Unterseite der Küvette angebracht.The induction coil or induction coils are attached to the underside of the cuvette using a hardenable, temperature-resistant two-component adhesive.

Durch die erfindungsgemäße Anordnung der elektrischen Induktionsbeheizung erfolgt somit die Erhitzung des Kochguts in der Wok-Pfanne auch lokal in gleicher Weise wie über einer Gasflamme. Die Induktionsheizung läßt sich trägheitslos regeln, und die Keramiküvette wird durch das Induktionsfeld nicht erwärmt, so daß die Energieverluste sehr niedrig sind.Due to the arrangement of the electric induction heating according to the invention, the items to be cooked are also heated locally in the wok pan in the same way as over a gas flame. The induction heating can be controlled without inertia, and the ceramic cell is not heated by the induction field, so that the energy losses are very low.

Eine aus Keramikmaterial bestehende Küvette kann in der Weise hergestellt werden, daß man eine Lithium-Aluminium-Silikat-Mischung im Töpferverfahren zu einer Küvette geeigneter Form und Größe formt und diese nach Trocknung bei 1150°C brennt. Anschließend wird eine Glasur aus Aluminiumsilikat mit einem geringen Bleizusatz aufgebracht und bei 1000°C nachgebrannt.A cuvette made of ceramic material can be produced in such a way that a lithium-aluminum-silicate mixture is shaped into a cuvette of suitable shape and size in a pottery process and this burns after drying at 1150 ° C. Then a glaze made of aluminum silicate is applied with a small amount of lead and fired at 1000 ° C.

Ein besonders gut geeignetes Grundmaterial besteht aus den Grundstoffen Ton und Lithiumsilikat₁ die in einem solchen Verhältnis vermischt werden, daß der Wärmeausdehnungskoeffizient der fertigen Küvette bei 800°C einen Wert von

≦2·10⁻⁶/°C hat.

Figure imgb0002

A particularly suitable base material consists of the base materials clay and lithium silicate which are mixed in such a ratio that the coefficient of thermal expansion of the finished cuvette at 800 ° C has a value of

≦ 2 · 10⁻⁶ / ° C.
Figure imgb0002

Ein wesentlicher Faktor ist auch die Wanddicke der Küvette. Die Wand darf aus Festigkeitsgründen nicht zu dünn sein. Andererseits nimmt mit zunehmender Wandstärke die Effektivität der Induktionsheizung ab, und auch die Wärmespannungen in dem Wandmaterial werden größer. Eine Wanddicke von 5 bis 7 mm wird den Forderungen am besten gerecht.An important factor is the wall thickness of the cuvette. For reasons of strength, the wall must not be too thin. On the other hand, the effectiveness of the induction heating decreases with increasing wall thickness, and the thermal stresses in the wall material also increase. A wall thickness of 5 to 7 mm best meets the requirements.

Die Küvette 3 wird in der dargestellten Weise in die Platte 2 eines Tischgerätes oder eines Kochherdes eingesetzt, so daß sie bündig mit der Oberfläche abschließt. Die Küvette muß dabei elastisch in der Deckplatte 2 eingebettet sein, damit Bewegungen, Stöße, Wärmedehnungen u. dgl. sich nicht schädlich auswirken können. Außerdem muß aus Gründen der Reinigung und der Hygiene die Küvette dicht und fugenlos umfaßt werden. Die Befestigung und Abdichtung erfolgt erfindungsgemäß durch eine Zwischenlage 5 aus temperaturbeständigem Silikonmastik.The cuvette 3 is inserted in the manner shown in the plate 2 of a tabletop or a cooker, so that it is flush with the surface. The cuvette must be elastically embedded in the cover plate 2 so that movements, shocks, thermal expansion and. Like. Can not have a harmful effect. In addition, for reasons of cleaning and hygiene, the cuvette must be tightly and seamlessly enclosed. The attachment and sealing is carried out according to the invention by an intermediate layer 5 made of temperature-resistant silicone plastic.
