Description

Die Erfindung betrifft eine induktionsbeheizte Kochstelle, bestehend aus einer Induktionsspule und einer darüber angeordneten Platte.The invention relates to an induction-heated hob, consisting of an induction coil and a plate arranged above it.

Die Beheizung von Kochstellen erfolgt üblicherweise durch elektrische Widerstandsstäbe, mit denen eine Kochplatte erhitzt wird, durch offene Gasflammen, die unmittelbar den Boden eines Kochgefäßes beaufschlagen, oder durch Infrarot-Heizkörper, mit denen Strahlungswärme auf die Kochgefäße übertragen wird. Die Infrarot-Heizkörper können mit elektrischem Strom oder mit Gas betrieben werden und sind zumeist unterhalb einer Glaskeramik-Kochplatte angeordnet, die die Wärmestrahlung ungehindert durchläßt.Cooking areas are usually heated by electrical resistance rods with which a hotplate is heated, by open gas flames which directly affect the bottom of a cooking vessel, or by infrared heating elements with which radiant heat is transferred to the cooking vessels. The infrared heaters can be operated with electric current or gas and are usually arranged below a glass ceramic hotplate that allows the heat radiation to pass through unhindered.

Außer den vorgenannten Wärmequellen wird zunehmend die Induktionsbeheizung eingesetzt. Dabei wird mit Hilfe einer Induktionsspule ein Magnetfeld erzeugt, das in dem Boden eines darüber befindlichen Kochgefäßes durch Induktionswirkung Wärme erzeugt. Voraussetzung ist dabei, daß der Boden des Kochgefäßes aus einem magnetisierbarem Material, insbesondere eisenhaltigem Material besteht, die das Kochgefäß aufnehmende Platte dagegen nicht magnetisierbar ist. Als Kochplatte ist daher wie bei der Infrarotbeheizung eine Glaskeramikplatte gut geeignet.In addition to the aforementioned heat sources, induction heating is increasingly being used. With the help of an induction coil, a magnetic field is generated that generates heat in the bottom of a cooking vessel located above it by induction. The prerequisite here is that the bottom of the cooking vessel consists of a magnetizable material, in particular iron-containing material, while the plate receiving the cooking vessel cannot be magnetized is. A glass ceramic plate is therefore well suited as a hotplate, as with infrared heating.

Außer dem Zubereiten von Speisen in Kochgefäßen ist es auch, insbesondere in gewerblichen Küchen, üblich, bestimmte Gerichte unmittelbar auf einer beheizten Brat-, Griddle- und Crepe-Platte zu erstellen. Hierfür werden widerstands- oder gasbeheizte Platten aus einem gut wärmeleitfähigen Material sowie inbesondere auch infrarotbeheizte Glaskeramikplatten eingesetzt, wobei bei letzteren allerdings nur die in das Brat- oder Griddlegut eindringende Wärmestrahlung ausgenutzt wird. Für eine Induktionsbeheizung sind solche Platten bislang dagegen nicht geeignet, da in ihnen das Induktionsfeld nicht in Wärme umgesetzt werden kann.In addition to preparing dishes in cooking vessels, it is also customary, especially in commercial kitchens, to prepare certain dishes directly on a heated roasting, griddle and crepe plate. Resistance- or gas-heated plates made of a highly thermally conductive material and, in particular, infrared-heated glass ceramic plates are used for this purpose, although in the latter only the heat radiation penetrating into the roasting or griddled material is used. However, such plates have so far not been suitable for induction heating, since the induction field cannot be converted into heat in them.

Der Erfindung liegt die Aufgabe zugrunde, eine induktionsbeheizte Kochstelle so auszubilden, daß sie ohne Kochgefäß als Brat-, Griddle- oder Crepeplatte verwendet werden kann.The invention has for its object to design an induction-heated hob so that it can be used as a roasting, griddle or crepe plate without a cooking vessel.

Die Aufgabe wird dadurch gelöst, daß die über der Induktionsspule angeordnete Platte aus eisenhaltigem Material besteht und zum Zubereiten von unmittelbar darauf aufgelegem Brat-, Griddle- oder Crepesgut ausgebildet ist.The object is achieved in that the plate arranged above the induction coil consists of iron-containing material and is designed to prepare roast, griddle or crepes items placed directly on it.

Die Zubereitung des Gutes erfolgt somit ohne gesondertes Kochgefäß unmittelbar auf der Platte. Die Platte wird durch das Induktionsfeld gleichmäßig erhitzt, wobei die Temperatur dem Gut entsprechend feinfühlig geregelt werden kann. Es besteht aber auch die Möglichkeit, Kochgefäße auf die Platte zu stellen und in üblicher Weise wie auf einer Kochplatte zu erhitzen.The food is therefore prepared directly on the plate without a separate cooking vessel. The plate is heated evenly by the induction field, whereby the temperature can be regulated in a sensitive manner according to the material. However, there is also the possibility of placing cooking vessels on the plate and heating them in the usual way as on a hot plate.

Die Platte kann als Kippbratpfanne mit einem allseitig umlaufenden Spritz- oder Tiegelrand ausgebildet sein.The plate can be designed as a tilting frying pan with an all-round spray or crucible rim.

In einer anderen Ausführungsform ist es möglich, die Platte als Zusatzteil über einer Glaskeramikplatte anzuordnen. Da das Induktionsfeld die Glaskeramikplatte ungehindert duchsetzt, wird die gesamte Energie auf die darüber befindliche Platte aus eisenhaltigem Material übertragen und dort in Wärme umgesetzt. Die Glaskeramikplatte bleibt alternativ weiterhin zum Aufsetzen von Kochgefäßen nutzbar.In another embodiment, it is possible to arrange the plate as an additional part over a glass ceramic plate. Since the induction field passes through the glass ceramic plate unhindered, all the energy is transferred to the plate made of ferrous material above and converted there into heat. Alternatively, the glass ceramic plate can still be used to place cooking vessels on top.

Bei der Anwendung der eisenhaltigen Platte oberhalb einer Glaskeramikplatte ist es zweckmäßig, zwischen den beiden Platten Abstandshalter aus einem Isolationsmaterial anzuordnen.When using the iron-containing plate above a glass ceramic plate, it is expedient to arrange spacers made of an insulation material between the two plates.

Weitere Ausgestaltungen der erfindungsgemäßen Kochstelle ergeben sich aus den Ansprüchen 2 bis 14.Further refinements of the hotplate according to the invention result from claims 2 to 14.

Die Erfindung wird nachfolgend anhand von zwei Ausführungsbeispielen unter Bezugnahme auf die Zeichnung näher erläutert. In der Zeichnung zeigen:

  • Fig. 1 eine Kochstelle mit einer als Kippbratpfanne ausgebildeten Platte,
  • Fig. 2 eine Kochstelle mit einer über einer Glaskeramikplatte angeordneten Brat-, Griddle- oder Crepe-Platte,
  • Fig. 3 eine herkömmliche Brat-, Griddle- oder Crepe-Platte in Form einer Brat- oder Griddleplatte , die über einem Elektroheizkörper angeordnet ist.
The invention is explained in more detail below using two exemplary embodiments with reference to the drawing. The drawing shows:
  • 1 is a hotplate with a plate designed as a tilting frying pan,
  • 2 shows a hotplate with a frying, griddle or crepe plate arranged over a glass ceramic plate,
  • Fig. 3 shows a conventional frying, griddle or crepe plate in the form of a frying or griddle plate which is arranged over an electric heater.

Fig. 3 zeigt im Querschnitt eine Bratplatte herkömmlicher Bauart. Sie besteht aus einem Elektroheizkörper 1 und einer darüber befindlichen Brat- oder Griddleplatte 2, die mit einem Spritzrand 3 versehen ist. Die elektrische Widerstandsheizung 1 wird mit einem Thermostat 4 geregelt. Unter dem Heizkörper befindet sich eine Wärmeisolation 5.Fig. 3 shows in cross section a frying plate of conventional design. It consists of an electric heating element 1 and a roasting or griddle plate 2 located above it, which is provided with a spray rim 3. The electrical resistance heater 1 is controlled by a thermostat 4. There is thermal insulation 5 under the radiator.

Das Bratgut wird auf die Platte 2 gelegt darauf zubereitet.The fried food is placed on the plate 2 and prepared on it.

Die erfindungsgemäße Platte nach Fig. 1 unterscheidet sich von der bekannten Platte dadurch, daß sie induktionsbeheizt ist. Die Platte 6 besteht zu diesem Zweck aus einem eisenhaltigen Material und ist über einer Induktionsspule 7 angeordnet. Die Induktionsspule wird von einem Generator 8 geregelt mit Strom beaufschlagt.1 differs from the known plate in that it is induction heated. For this purpose, the plate 6 consists of an iron-containing material and is arranged above an induction coil 7. The induction coil is supplied with current in a controlled manner by a generator 8.

Die Platte 6 kann aus einem für Koch- oder Bratplatten geeigneten verzugfreien Material, insbesondere Metall, bestehen, das nicht unbedingt magnetisierbar sein muß. Es genügt, wenn die Oberseite und ggfs. auch die Unterseite mit einem ferritischen Material beschichtet ist bzw. sind. Alternativ kann die Platte 6 auch aus hartverchromtem Stahl oder aus Edelstahl bestehen.The plate 6 can consist of a distortion-free material, in particular metal, suitable for hot plates or frying plates, which material does not necessarily have to be magnetizable. It is sufficient if the upper side and possibly also the lower side is or are coated with a ferritic material. Alternatively, the plate 6 can also consist of hard chrome-plated steel or stainless steel.

Die Heizenergie läßt sich über den Generator 8 ein- und ausschalten sowie feinfühlig regeln, so daß das aufgelegte Gut den Bedürfnissen entsprechend gegart werden kann.The heating energy can be switched on and off via the generator 8 and can be regulated sensitively so that the material placed on it can be cooked according to requirements.

Die Platte 6 gemäß Fig. 1 ist als Kippbratpfanne ausgebildet und zu diesem Zweck mit einem allseitig umlaufenden Spritz- oder Tiegelrand 9 versehen.The plate 6 according to FIG. 1 is designed as a tilting frying pan and for this purpose is provided with an all-round spray or crucible rim 9.

Bei dem Ausführungsbeispiel nach Fig. 2 ist die aus eisenhaltigem Material bestehende Platte 10 als Zusatzteil für eine induktionsbeheizte Kochstelle mit einer Glaskeramikplatte 11, einer Induktionsspule 12 und einem Generator 13 ausgebildet. Bei entfernter Platte 10 können auf die Glaskeramikplatte 11 Kochgefäße mit ferritischem Boden gestellt werden, die durch das Magnetfeld erhitzt werden. Wenn Speisen auf einer Bratplatte zubereitet werden sollen, wird die Platte 10 über die Platte 11 gesetzt, wobei isolierende Abstandhalter 13 vorgesehen sind. Da das Magnetfeld die Glaskeramikplatte 11 ungehindert durchsetzt, wird seine gesamte Energie auf die aus eisenhaltigem Material bestehende Platte 10 übertragen und dort zum Braten genutzt.In the embodiment according to FIG. 2, the plate 10 consisting of iron-containing material is designed as an additional part for an induction-heated hotplate with a glass ceramic plate 11, an induction coil 12 and a generator 13. When the plate 10 is removed, 11 cooking vessels with a ferritic base can be placed on the glass ceramic plate and are heated by the magnetic field. If dishes are to be prepared on a frying plate, the plate 10 is placed over the plate 11, insulating spacers 13 being provided. Since the magnetic field passes through the glass ceramic plate 11 unhindered, it becomes transfer all of the energy to the plate 10 made of ferrous material and use it there for frying.

Die Platte 10 ist mit einem Spritzrand 14 versehen, der an der hinteren Längsseite und ggfs. an den beiden Schmalseiten vorgesehen sein kann. Der Spritzrand 14 kann ferner als entfernbares Zusatzteil aufsteckbar ausgebildet oder fest angeordnet sein.The plate 10 is provided with a spray edge 14 which can be provided on the rear long side and, if appropriate, on the two narrow sides. The spray rim 14 can also be configured as a removable additional part, or can be arranged in a fixed manner.

Die Platte 10 weist ferner an ihrer Oberseite parallel zu ihren Rändern eine ringsum laufende Rille 15 auf, die als Saftrinne zur Aufnahme von ablaufendem flüssigem Speisegut dient.The plate 10 also has on its top parallel to its edges an all-round groove 15, which serves as a juice channel for receiving liquid food.
