Dadurch kann insbesondere eine kompakte Ausgestaltung erreicht werden. Insbesondere kann eine hohe induktive Effizienz erzielt werden. Ist das Induktionsheizelement durch das thermische Isolationselement von der Muffelwandung beabstandet, kann insbesondere eine vergleichbare Effizienz wie bei einem Koch- feld erreicht werden. It is also proposed that the induction heating element is spaced apart by a maximum of 3 mm, in particular by a maximum of 2 mm, advantageously by a maximum of 1 mm, particularly advantageously by a maximum of 0.6 mm and preferably by a maximum of 0.4 mm from the muffle wall, in particular in FIG a direction perpendicular to a Haupsterstreckungsebne the Muffelwandung direction. A "main extension plane" of an object is to be understood in particular as meaning a plane which is parallel to a largest side surface of a smallest imaginary geometric cuboid which just completely surrounds the object, and in particular runs through the center of the cuboid Thickness of not more than 3 mm, in particular not more than 2 mm, advantageously not more than 1 mm, particularly advantageously not more than 0.6 mm and preferably not more than 0.4 mm, which in particular makes it possible to achieve a compact design If the induction heating element is spaced apart from the muffle wall by the thermal insulation element, in particular a comparable efficiency can be achieved as with a cooking field.
Zudem wird vorgeschlagen, dass das Abschirmelement um mindestens 20 mm, insbesondere um mindestens 25 mm, vorteilhaft um mindestens 30 mm, besonders vorteilhaft um mindestens 35 mm und vorzugsweise um mindestens 40 mm von der Muffelwandung und/oder von dem Induktionsheizelement beabstandet ist. Das Abschirmelement ist insbesondere um maximal 100 mm, insbesondere um maximal 80 mm, vorteilhaft um maximal 70 mm und vorzugsweise um maximal 60 mm von der Muffelwandung und/oder von dem Induktionsheizelement beabstandet.

Dadurch kann insbesondere ein ausreichend großer Zwischenraum zwischen dem Abschirmelement und der Muffelwandung geschaffen werden, um insbesondere weitere Objekte in dem Zwischenraum anordnen zu können und/oder um insbesondere eine Erhitzung des Abschirmelements vermeiden zu können. Insbesondere können elektromagnetische Verluste in dem Abschirmelement gering gehalten werden.

In particular, the shielding element is spaced at least 5 times, in particular at least 7 times, advantageously at least 8 times, particularly advantageously at least 9 times and preferably at least 10 times as far from the muffle wall and / or from the induction heating element as the induction heating element from the muffle wall. As a result, in particular, a sufficiently large intermediate space can be created between the shielding element and the muffle wall in order, in particular, to be able to arrange further objects in the intermediate space and / or in particular to prevent heating of the shielding element. In particular, electromagnetic losses in the shielding can be kept low.
Beispielsweise könnte das Induktionsheizelement zu einer induktiven Erhitzung und/oder Beheizung zumindest eines in dem Garraum befindlichen und/oder eingebrachten Gargeschirrs vorgesehen sein. Vorzugsweise ist das Induktionsheizelement dazu vorgesehen, die Muffelwandung induktiv zu beheizen, wodurch insbesondere eine besonders effiziente Erhitzung und/oder Beheizung von in dem Garraum befindlichen und/oder eingebrachten Lebensmitteln und/oder ein optimales Garergebnis erzielt werden kann. For example, the induction heating element could be provided for inductive heating and / or heating of at least one cooking utensil located and / or placed in the cooking space. Preferably, the induction heating is intended to heat the muffle wall inductively, which in particular a particularly efficient heating and / or heating located in the cooking chamber and / or introduced food and / or an optimal cooking result can be achieved.
Ferner wird vorgeschlagen, dass das Induktionsheizelement die Muffelwandung in wenigs- tens einem Betriebszustand auf eine Temperatur von mindestens 300°C, insbesondere von mindestens 400°C, vorteilhaft von mindestens 500°C und vorzugsweise von mindestens 550°C aufheizt, wodurch insbesondere eine Vielzahl verschiedener Betriebsmodi und/oder Garprogramme ermöglicht werden kann. Insbesondere können hohe Betriebstemperaturen erzielt werden. It is also proposed that the induction heating element heat the muffle wall in at least one operating state to a temperature of at least 300 ° C., in particular of at least 400 ° C., advantageously of at least 500 ° C. and preferably of at least 550 ° C. various operating modes and / or cooking programs can be enabled. In particular, high operating temperatures can be achieved.
Eine besonders hohe Effizienz kann insbesondere erreicht werden durch ein Gargerät, insbesondere durch ein Induktionsgargerät und vorteilhaft durch einen Induktionsbackofen, mit zumindest einer erfindungsgemäßen Gargerätevorrichtung, insbesondere mit zumindest einer erfindungsgemäßen Induktionsgargerätevornchtung und vorteilhaft mit zumindest einer erfindungsgemäßen Induktionsbackofenvorrichtung.

Weiterhin wird vorgeschlagen, dass das Gargerät, insbesondere das Induktionsgargerät und der Induktionsbackofen, frei von Ferriten ist, welche zu einer Leitung eines durch das Induktionsheizelement erzeugten magnetischen Felds vorgesehen sind. Dadurch können insbe- sondere geringe Kosten und/oder ein geringes Gesamtgewicht des Gargeräts erzielt werden. Furthermore, it is proposed that the cooking appliance, in particular the induction cooking appliance and the induction baking oven, be free of ferrites, which are provided for conducting a magnetic field generated by the induction heating element.
