Fig. 1 zeigt zumindest einen Teil eines beispielhaft als Backofen ausgebildeten Gargeräts 10a in einer schematischen Darstellung. Das Gargerät 10a ist als Induktionsgargerät, im vorliegenden Fall insbesondere als Induktionsbackofen, ausgebildet. Alternativ könnte ein Gargerät als ein Induktionskochfeld, als ein Induktionsgrillgerät und/oder als als eine Induktionsmikrowelle ausgebildet sein. Es ist jedoch auch denkbar, dass das Gargerät als ein herkömmliches Gargerät, beispielsweise als eine Mikrowelle, ausgebildet ist. 1 shows a schematic representation of at least one part of a cooking appliance 10a designed as an oven by way of example. The cooking appliance 10a is designed as an induction cooking appliance, in the present case in particular as an induction baking oven. Alternatively, a cooking appliance could be used as an induction hob, as an induction grill and / or as one Induction microwave to be formed.

The device housing 12a defines a, in particular contiguous, cooking chamber 14a. For this purpose, the device housing 12a comprises an outer housing (not shown) and a muffle 16a which is arranged within the outer housing and delimits the cooking chamber 14a. In addition, the cooking device device comprises a device closure element (not shown). The device closure element is designed in the present case as a device flap. The device closure element is intended to close the cooking chamber 14a. Alternatively, however, a device closure element could also be designed as a device door.

Die Heizeinheit 24a ist zwischen einer Muffelwand der Muffel 16a und dem Außengehäuse angeordnet. Die Heizeinheit 24a ist dabei an der Muffelwand angeordnet, insbesondere befestigt.

In particular, a cooking appliance device could comprise at least two, advantageously at least three and particularly preferably at least four heating units.
In Figur 2 ist die Heizeinheit 24a in einer Explosionsdarstellung dargestellt. Die Heizeinheit 24a ist dazu vorgesehen, ein in dem Garraum 14a befindliches Gargut zu erhitzen. Dazu umfasst die Heizeinheit 24a eine Heizspule 30a. Die Heizspule 30a ist als Induktionsheizelement ausgebildet. Die Heizspule 30a ist aus einem bandförmigen Heizleiter ausgebildet, welcher im vorliegenden Fall insbesondere einen rechteckigen Querschnitt aufweist. Die Heizspule 30a ist aus einem einzelnen Heizleiter ausgebildet. Die Heizspule 30a ist aus Kupfer ausgebildet. Die Heizspule 30a umfasst eine Mehrzahl an Windungen 34a, 36a. Im vorliegenden Fall umfasst die Heizspule 30a insgesamt siebzehn Windungen 34a, 36a, wobei in den Figuren der Übersichtlichkeit halber lediglich zwei der Windungen 34a, 36a mit Bezugszeichen versehen sind. Die Windungen 34a, 36a der Heizspule 30a bilden eine flache Spulenebene aus. Alle Windungen 34a, 36a der Heizspule 30a sind dabei in der Spulenebene angeordnet. Zudem weist die Heizspule 30a bei Betrachtung in einer Draufsicht eine im Wesentlichen rechteckige Form auf. Alternativ könnte eine Heizeinheit mehrere Heizspulen aufweisen. Zudem könnte eine Heizspule eine von siebzehn verschiedene Anzahl an Windungen aufweisen. Ferner könnte eine Heizspule bei Betrachtung in einer Draufsicht eine im Wesentlichen runde, ovale und/oder dreieckige Form aufweisen. FIG. 2 shows the heating unit 24a in an exploded view. The heating unit 24a is intended to heat a cooking product located in the cooking chamber 14a. For this purpose, the heating unit 24a comprises a heating coil 30a. The heating coil 30a is designed as an induction heating element. The heating coil 30a is formed from a band-shaped heating conductor, which in the present case has in particular a rectangular cross-section. The heating coil 30a is formed of a single heating conductor. The heating coil 30a is formed of copper. The heating coil 30a includes a plurality of turns 34a, 36a. In the present case, the heating coil 30a comprises a total of seventeen windings 34a, 36a, wherein in the figures for the sake of clarity only two of the windings 34a, 36a are provided with reference numerals. The windings 34a, 36a of the heating coil 30a form a flat coil plane. All windings 34a, 36a of the heating coil 30a are arranged in the coil plane. In addition, the heating coil 30a has a substantially rectangular shape when viewed in a plan view. Alternatively, a heating unit could have several heating coils. In addition, a heating coil could have one of seventeen different number of turns. Furthermore, a heating coil could have a substantially round, oval and / or triangular shape when viewed in a plan view.
Insbesondere um eine Isolation der Heizspule 30a gegenüber der Muffel 16a und/oder gegenüber dem Außengehäuse zu ermöglichen, weist die Heizeinheit 24a ferner zwei Isolationselemente 26a, 28a, insbesondere ein erstes Isolationselement 26a und ein zweites Isolationselement 28a, auf (vgl. insbesondere Figuren 2 und 3). Die Isolationselemente 26a, 28a sind zumindest im Wesentlichen baugleich ausgebildet. Die Isolationselemente 26a, 28a bestehen aus einem elektrisch isolierenden Material, im vorliegenden Fall insbesondere Glimmer. Die Isolationselemente 26a, 28a sind jeweils einstückig ausgebildet. Die Isolationselemente 26a, 28a sind flächig ausgebildet. Eine maximale Materialstärke der Isolationselemente 26a, 28a beträgt dabei höchstens 0,3 mm. In einem montierten Zustand sind die Isolationselemente 26a, 28a, insbesondere bezüglich der Spulenebene, auf unterschiedlichen Seiten der Heizspule 30a angeordnet. Eine jeweilige Haupterstreckungsebene der Isolationselemente 26a, 28a ist dabei parallel zu der Spulenebene angeordnet. Die Heizspule 30a ist zwischen den Isolationselementen 26a, 28a angeordnet. Ferner kontaktieren die Isolationselemente 26a, 28a die Heizspule 30a beidseitig. Alternativ könnte eine Gargerätevorrichtung mehr als zwei Isolationselemente aufweisen. Auch könnten Isolationselemente grundsätzlich verschieden voneinander ausgebildet sein. In particular, in order to enable an insulation of the heating coil 30a with respect to the muffle 16a and / or with respect to the outer housing, the heating unit 24a further comprises two insulation elements 26a, 28a, in particular a first insulation element 26a and a second insulation element 28a (see in particular FIGS 3). The insulation elements 26a, 28a are at least substantially identical in construction. The insulation elements 26a, 28a are made of an electrically insulating material, in the present case in particular mica. The insulation elements 26a, 28a are each formed in one piece. The insulation elements 26a, 28a are formed flat. A maximum material thickness of the insulation elements 26a, 28a is at most 0.3 mm. In an assembled state, the insulation elements 26a, 28a, in particular with respect to the coil plane, are arranged on different sides of the heating coil 30a. A respective main extension plane of the insulation elements 26a, 28a is arranged parallel to the coil plane. The heating coil 30a is disposed between the insulating members 26a, 28a. Further, the insulation members 26a, 28a contact the heating coil 30a on both sides. Alternatively, a cooking appliance device could have more than two isolation elements. Also, isolation elements could basically be formed differently from each other.
Ferner weist wenigstens eines der Isolationselemente 26a, 28a, im vorliegenden Fall insbesondere das erste Isolationselement 26a, eine Isolationsausnehmung 42a auf. Die Isolationsausnehmung 42a ist dabei in einem zentralen Bereich des ersten Isolationselements 26a angeordnet und dient insbesondere zu einer elektrischen Kontaktierung der Heizspule 30a. Alternativ könnte eine Isolationsausnehmung in einem beliebigen anderen Bereich eines Isolationselements, beispielsweise in einem Randbereich und/oder im Bereich einer Kante, angeordnet sein. Des Weiteren könnten auch beide Isolationselemente eine Isolationsausnehmung aufweisen. Furthermore, at least one of the insulation elements 26a, 28a, in the present case in particular the first insulation element 26a, has an insulation recess 42a. The isolation recess 42a is arranged in a central region of the first insulation element 26a and serves, in particular, for electrical contacting of the heating coil 30a. Alternatively, an insulation recess could be arranged in any other area of an insulation element, for example in an edge region and / or in the region of an edge. Furthermore, both insulation elements could also have an isolation recess.
Figur 4 zeigt die Heizeinheit 24a in einer Schnittdarstellung in einem vollständig montierten Zustand. Dabei sind die Isolationselemente 26a, 28a, zumindest in einer Richtung parallel zu einer Haupterstreckungsebene der Heizspule 30a betrachtet, zwischen den Wndungen 34a, 36a angeordnet. Alternativ könnte jedoch auch lediglich ein Isolationselement zwischen Windungen einer Heizspule angeordnet sein. Im vorliegenden Fall umgreifen die Isolationselemente 26a, 28a die Windungen 34a, 36a in Umfangsrichtung jeweils zu zumindest 30 %, wodurch insbesondere eine vorteilhafte Isolation zwischen den Windungen 34a, 36a der Heizspule 30a erreicht werden kann. Im vorliegenden Fall umgreift das erste Isolationselement 26a die Windungen 34a, 36a zu 50 % von einer ersten Seite der Heizspule 30a. Ferner umgreift das zweite Isolationselement 28a die Wndungen 34a, 36a zu 50 % von einer zweiten Seite der Heizspule 30a. Die Isolationselemente 26a, 28a sind dabei derart angeordnet, dass die Isolationselemente 26a, 28a einander kontaktieren. Im vorliegenden Fall sind die Isolationselemente 26a, 28a dabei einstückig verbunden. Alternativ könnte auf eine einstückige Verbindung von Isolationselementen jedoch auch verzichtet werden. Figure 4 shows the heating unit 24a in a sectional view in a fully assembled state. In this case, the insulation elements 26a, 28a, viewed in at least one direction parallel to a main extension plane of the heating coil 30a, are arranged between the walls 34a, 36a. Alternatively, however, could also only an isolation element between Windings of a heating coil can be arranged. In the present case, the insulation elements 26a, 28a surround the windings 34a, 36a in the circumferential direction in each case to at least 30%, whereby in particular an advantageous insulation between the windings 34a, 36a of the heating coil 30a can be achieved. In the present case, the first insulation element 26a surrounds the windings 34a, 36a by 50% from a first side of the heating coil 30a. Furthermore, the second insulation element 28a surrounds the walls 34a, 36a by 50% from a second side of the heating coil 30a. The insulation elements 26a, 28a are arranged such that the insulation elements 26a, 28a contact each other. In the present case, the insulation elements 26a, 28a are integrally connected. Alternatively, however, an integral connection of insulation elements could also be dispensed with.
Figur 5 zeigt ein beispielhaftes Ablaufdiagramm eines Verfahrens zur Herstellung der Gargerätevorrichtung. In einem ersten Verfahrensschritt 100a wird zumindest eines der Isolationselemente 26a, 28a mit einem Kunstharz imprägniert. Alternativ könnte auf eine derartige Imprägnierung jedoch auch verzichtet werden. FIG. 5 shows an example flow diagram of a method for producing the cooking appliance device. In a first method step 100a, at least one of the insulation elements 26a, 28a is impregnated with a synthetic resin. Alternatively, however, such an impregnation could also be dispensed with.
In einem zweiten Verfahrensschritt 102a wird die Heizspule 30a zwischen den Isolationselementen 26a, 28a platziert. Anschließend werden die Isolationselemente 26a, 28a plastisch verformt. Dazu wird zumindest eines der Isolationselemente 26a, 28a zumindest in einer Richtung parallel zu einer Haupterstreckungsebene der Heizspule 30a mit einem erhöhten Druck 110a, im vorliegenden Fall einem Druck von zumindest 15 kg/cm2, und einer erhöhten Temperatur 112a, im vorliegenden Fall einer Temperatur von zumindest 300°C, beaufschlagt, sodass sich die Isolationselemente 26a, 28a insbesondere formschlüssig um die Windungen 34a, 36a legen (vgl. insbesondere auch Figur 6). In a second method step 102a, the heating coil 30a is placed between the insulation elements 26a, 28a. Subsequently, the insulation elements 26a, 28a are plastically deformed. For this, at least one of the insulation elements 26a, 28a is at least in a direction parallel to a main extension plane of the heating coil 30a with an increased pressure 110a, in the present case a pressure of at least 15 kg / cm 2 , and an elevated temperature 112a, in the present case a temperature of at least 300 ° C, acted upon, so that the insulation elements 26a, 28a in particular form fit around the windings 34a, 36a set (see in particular also Figure 6).
Ferner werden in einem dritten Verfahrensschritt 104a die Isolationselemente 26a, 28a ausgehärtet. Furthermore, in a third method step 104a, the insulation elements 26a, 28a are cured.
