In at least one disassembled state, in particular before assembly begins, the channel elements are in particular separate from one another. In the assembled state, the channel elements are in particular connected to one another and advantageously fastened to one another.

Beispielsweise kƶnnte zumindest eines der Kanalelemente ein Begrenzungselement sein, welches insbesondere zusƤtzlich zu einer Begrenzungsfunktion des Kanals frei von weiteren Funktionen sein kƶnnte. Die weitere Funktion kƶnnte beispielsweise eine Isolationsfunktion und/oder eine TrƤgerfunktion und/oder eine Abschirmfunktion und/oder eine Stromleitungsfunktion und/oder eine Funktion der elektrischen Kontaktierung sein. Das zweite Kanalelement ist von einem Funktionsteil gebildet, welches zusƤtzlich zu einer Begrenzungsfunktion des Kanals zumindest eine weitere Funktion aufweist und/oder ausfĆ¼hrt. Insbesondere ist die wenigstens abschnittsweise Bildung des Kanals eine Nebenfunktion des zweiten Kanalelements.

In particular, the formation of the channel at least in sections is a secondary function of the second channel element. The second channel element has in particular a main function, which is different from a function of the at least section-wise formation of the channel. A high degree of flexibility can be achieved in this way. In particular, a small number of components and / or a small space requirement can be achieved.

Die Kochfeldvorrichtung weist zumindest eine Leiterplatte auf, welche das zweite Kanalelement wenigstens im Wesentlichen ausbildet.

As a result, in particular additional components for limiting the channel and / or for forming the channel can be dispensed with. In particular, low costs and / or low inventory levels can be achieved.

Weiterhin wird vorgeschlagen, dass die Kanaleinheit eine Befestigungseinheit aufweist, welche dazu vorgesehen ist, das erste Kanalelement und das zweite Kanalelement in dem montierten Zustand kraftschlĆ¼ssig und/oder formschlĆ¼ssig aneinander zu befestigen. Die Befestigungseinheit ist insbesondere dazu vorgesehen, das erste Kanalelement und das zweite Kanalelement in dem montierten Zustand werkzeuglos lƶsbar aneinander zu befestigen. Dadurch kann insbesondere eine einfache Montage und/oder Demontage erzielt werden.Furthermore, it is proposed that the duct unit has a fastening unit which is provided to fasten the first duct element and the second duct element to one another in the assembled state in a force-locking and / or form-fitting manner. The fastening unit is in particular provided for releasably fastening the first duct element and the second duct element to one another in the assembled state without tools. In particular, simple assembly and / or disassembly can thereby be achieved.

Beispielsweise kƶnnte die Befestigungseinheit dazu vorgesehen sein, das erste Kanalelement und das zweite Kanalelement in dem montierten Zustand mittels einer Schraubverbindung und/oder mittels einer durch Verriegelung hergestellten Verbindung und/oder mittels einer durch Klemmung hergestellten Verbindung aneinander zu befestigen. Vorzugsweise ist die Befestigungseinheit als eine Rasteinheit ausgebildet und insbesondere dazu vorgesehen, das erste Kanalelement und das zweite Kanalelement in dem montierten Zustand insbesondere werkzeuglos lƶsbar miteinander zu verrasten. Unter einer "Rasteinheit" soll dabei insbesondere eine Einheit mit wenigstens einem Rastelement verstanden werden, das bei einem Befestigungsvorgang elastisch ausgelenkt wird, um anschlieƟend durch eine innere Spannkraft hinter einem korrespondierenden Rastelement einzurasten. Dadurch kann insbesondere eine einfache Ausgestaltung bereitgestellt werden.For example, the fastening unit could be provided to fasten the first channel element and the second channel element to one another in the assembled state by means of a screw connection and / or by means of a connection made by locking and / or by means of a connection made by clamping. The fastening unit is preferably designed as a latching unit and, in particular, is provided for releasably latching the first channel element and the second channel element to one another in the assembled state, in particular without tools. A ā€œlatching unitā€ is to be understood in particular to mean a unit with at least one latching element which is elastically deflected during a fastening process in order to then latch behind a corresponding latching element by means of an internal clamping force. In this way, in particular a simple configuration can be provided.

Beispielsweise kƶnnten das erste Kanalelement und das zweite Kanalelement in dem montierten Zustand Ć¼ber einen Anteil von mindestens 70 %, insbesondere von mindestens 80 %, vorteilhaft von mindestens 85 %, besonders vorteilhaft von mindestens 90 % und vorzugsweise von mindestens 95 % einer LƤngserstreckung der Kanaleinheit zusammen den Kanal ausbilden. Vorzugsweise weist die Kanaleinheit zumindest ein drittes Kanalelement auf, welches insbesondere von dem ersten Kanalelement und von dem zweiten Kanalelement verschieden ist und welches in dem montierten Zustand zusammen mit dem ersten Kanalelement und dem zweiten Kanalelement den Kanal wenigstens im Wesentlichen und vorteilhaft vollstƤndig ausbildet. Das erste Kanalelement und das dritte Kanalelement bilden in dem montierten Zustand Ć¼ber einen Anteil von mindestens 10 %, insbesondere von mindestens 20 %, vorteilhaft von mindestens 25 %, besonders vorteilhaft von mindestens 30 % und vorzugsweise von mindestens 35 % einer LƤngserstreckung der Kanaleinheit zusammen einen Kanal aus. Dadurch kƶnnen die Betriebseigenschaften insbesondere weiter gesteigert werden.For example, the first duct element and the second duct element in the assembled state could together comprise a length of the duct unit over a proportion of at least 70%, in particular of at least 80%, advantageously of at least 85%, particularly advantageously of at least 90% and preferably of at least 95% train the channel. The channel unit preferably has at least one third channel element, which is in particular different from the first channel element and from the second channel element and which, in the assembled state together with the first channel element and the second channel element, at least essentially and advantageously completely forms the channel. In the assembled state, the first channel element and the third channel element together form a portion of at least 10%, in particular at least 20%, advantageously at least 25%, particularly advantageously at least 30% and preferably at least 35% of a longitudinal extent of the channel unit Channel off. As a result, the operating properties can in particular be further increased.

Weiterhin wird vorgeschlagen, dass das zweite Kanalelement und das dritte Kanalelement in dem montierten Zustand gemeinsam eine Begrenzungswand des Kanals ausbilden. Insbesondere ist die Begrenzungswand des Kanals eine insbesondere seitliche Begrenzung des Kanals. Dadurch kann insbesondere eine flexible Anpassung der Begrenzungswand des Kanals an ƶrtliche Gegebenheiten ermƶglicht werden.It is further proposed that the second duct element and the third duct element jointly form a boundary wall of the duct in the assembled state. In particular, the boundary wall of the channel is a lateral limitation of the channel in particular. In particular, this allows a flexible adaptation of the boundary wall of the channel to local conditions.

Ferner wird vorgeschlagen, dass die Kanaleinheit eine weitere Befestigungseinheit aufweist, welche dazu vorgesehen ist, das erste Kanalelement und das dritte Kanalelement in dem montierten Zustand kraftschlĆ¼ssig und/oder formschlĆ¼ssig aneinander zu befestigen. Beispielsweise kƶnnte die weitere Befestigungseinheit dazu vorgesehen sein, das erste Kanalelement und das dritte Kanalelement in dem montierten Zustand mittels einer Schraubverbindung und/oder mittels einer durch Verriegelung hergestellten Verbindung und/oder mittels einer Rastverbindung aneinander zu befestigen. Vorteilhaft ist die weitere Befestigungseinheit dazu vorgesehen, das erste Kanalelement und das dritte Kanalelement in dem montierten Zustand mittels einer durch Klemmung hergestellten Verbindung und/oder mittels einer Steckverbindung aneinander zu befestigen. Dadurch kann insbesondere ein Entweichen von KĆ¼hlluft aus der Kanaleinheit, insbesondere aus dem Kanal, vermieden und/oder eine perfekte Verbindung zwischen dem ersten Kanalelement und dem dritten Kanalelement bereitgestellt werden.It is further proposed that the channel unit has a further fastening unit, which is provided to fasten the first channel element and the third channel element to one another in the assembled state in a non-positive and / or positive manner. For example, the further fastening unit could be provided to fasten the first channel element and the third channel element to one another in the assembled state by means of a screw connection and / or by means of a connection produced by locking and / or by means of a latching connection. The further fastening unit is advantageously provided for fastening the first duct element and the third duct element to one another in the assembled state by means of a connection produced by clamping and / or by means of a plug connection. This in particular prevents cooling air from escaping from the duct unit, in particular from the duct, and / or provides a perfect connection between the first duct element and the third duct element.

Zudem wird vorgeschlagen, dass das dritte Kanalelement dazu vorgesehen ist, in dem montierten Zustand einen Hƶhenunterschied zwischen einer LuftfĆ¼hrungsflƤche der GeblƤseeinheit und einer dem ersten Kanalelement zugewandten zweiten LuftfĆ¼hrungsflƤche des zweiten Kanalelements zu Ć¼berbrĆ¼cken. Insbesondere weist das dritte Kanalelement zumindest eine dritte LuftfĆ¼hrungsflƤche auf, welche insbesondere in dem montierten Zustand schrƤg relativ zu der LuftfĆ¼hrungsflƤche der GeblƤseeinheit und/oder zu der zweiten LuftfĆ¼hrungsflƤche des zweiten Kanalelements ausgerichtet ist. Insbesondere ist das dritte Kanalelement dazu vorgesehen, die KĆ¼hlluft ausgehend von der GeblƤseeinheit zumindest in Richtung des KĆ¼hlkƶrpers zu lenken. Unter einer "LuftfĆ¼hrungsflƤche" einer Einheit soll insbesondere eine OberflƤche der Einheit verstanden werden, die dazu vorgesehen ist, in dem Betriebszustand die KĆ¼hlluft wenigstens teilweise zu fĆ¼hren und/oder wenigstens abschnittsweise in Kontakt mit der KĆ¼hlluft zu stehen. Dadurch kann insbesondere eine perfekte Anpassung an eine vorhandene Geometrie ermƶglicht werden, wodurch insbesondere geringe Verluste an KĆ¼hlluft erreicht werden kƶnnen. Insbesondere kann eine flexible Ausgestaltung ermƶglicht werden.In addition, it is proposed that the third duct element be provided in the assembled state to bridge a height difference between an air duct surface of the blower unit and a second air duct surface of the second duct element facing the first duct element. In particular, the third duct element has at least one third air duct surface, which in the assembled state is oriented obliquely relative to the air duct surface of the blower unit and / or to the second air duct surface of the second duct element. In particular, the third duct element is provided to guide the cooling air at least in the direction of the heat sink, starting from the blower unit. An ā€œair guide surfaceā€ of a unit is to be understood in particular as a surface of the unit which is intended to at least partially guide the cooling air in the operating state and / or to be in contact with the cooling air at least in sections. In particular, this enables a perfect adaptation to an existing geometry, which in particular allows small losses of cooling air to be achieved. In particular, a flexible configuration can be made possible.

Beispielsweise kƶnnte das dritte Kanalelement insbesondere zusƤtzlich zu einer Begrenzungsfunktion des Kanals frei von weiteren Funktionen sein. Vorzugsweise ist das dritte Kanalelement von einem Funktionsteil gebildet, welches zusƤtzlich zu einer Begrenzungsfunktion des Kanals zumindest eine weitere Funktion aufweist und/oder ausfĆ¼hrt. Insbesondere ist die wenigstens abschnittsweise Bildung des Kanals eine Nebenfunktion des dritten Kanalelements. Das dritte Kanalelement weist insbesondere eine Hauptfunktion auf, welche von einer Funktion der wenigstens abschnittsweisen Bildung des Kanals verschieden ist. Dadurch kann insbesondere eine hohe FlexibilitƤt erreicht werden. Insbesondere kann eine geringe Anzahl an Bauteilen und/oder ein geringer Platzbedarf erzielt werden.For example, in addition to a limiting function of the channel, the third channel element could be free of further functions. Preferably that is third channel element is formed by a functional part which, in addition to a limiting function of the channel, has and / or carries out at least one further function. In particular, the formation of the channel at least in sections is a secondary function of the third channel element. The third channel element has in particular a main function, which is different from a function of forming the channel at least in sections. A high degree of flexibility can be achieved in this way. In particular, a small number of components and / or a small space requirement can be achieved.

Ferner wird vorgeschlagen, dass die Kochfeldvorrichtung eine ElektroniktrƤgereinheit aufweist, welche dazu vorgesehen ist, in dem montierten Zustand zumindest eine Leiterplatte zu lagern, insbesondere tragen und/oder zu halten. Insbesondere ist die ElektroniktrƤgereinheit dazu vorgesehen, in dem montierten Zustand die Leiterplatte zu lagern, welche insbesondere das zweite Kanalelement wenigstens im Wesentlichen ausbildet. Die Kochfeldvorrichtung weist insbesondere zumindest ein InnengehƤuse auf, welches insbesondere in dem montierten Zustand wenigstens zu einem GroƟteil einem Bediener verborgen und/oder unzugƤnglich angeordnet ist und welches insbesondere zu einer ErgƤnzung und/oder UnterstĆ¼tzung eines AuƟengehƤuses vorgesehen ist. Das InnengehƤuse kƶnnte beispielsweise dazu vorgesehen sein, elektrische und/oder elektronische Kochfeldkomponenten gegenĆ¼ber dem AuƟengehƤuse, welches insbesondere elektrisch leitend ausgebildet sein kƶnnte, wenigstens im Wesentlichen elektrisch zu isolieren. Das InnengehƤuse kƶnnte insbesondere aus wenigstens einem elektrisch isolierenden Material ausgebildet sein. Die ElektroniktrƤgereinheit ist insbesondere einstĆ¼ckig mit einem InnengehƤuse ausgebildet. Unter einem "AuƟengehƤuse" soll insbesondere eine Einheit verstanden werden, welche in dem montierten Zustand einem Bediener zugewandt und/oder zugƤnglich angeordnet ist und welche insbesondere in dem montierten Zustand mit einer Kochfeldplatte verbunden ist und insbesondere mit der Kochfeldplatte einen GerƤteinnenraum wenigstens zu einem GroƟteil begrenzt und/oder definiert. Das AuƟengehƤuse kƶnnte insbesondere aus wenigstens einem elektrisch leitenden Material ausgebildet sein. Die Kochfeldvorrichtung weist insbesondere die Kochfeldplatte auf, welche in dem montierten Zustand insbesondere zu einem Aufstellen von Gargeschirr vorgesehen ist. Dadurch kann insbesondere eine hohe Sicherheit und/oder eine geschĆ¼tzte Lagerung der Leiterplatte ermƶglicht werden.It is further proposed that the cooktop device has an electronics carrier unit, which is provided for storing, in particular carrying and / or holding, at least one printed circuit board in the assembled state. In particular, the electronics carrier unit is provided for storing the printed circuit board in the assembled state, which in particular forms the second channel element at least substantially. The cooktop device has, in particular, at least one inner housing, which, in particular in the assembled state, is at least largely hidden from an operator and / or arranged inaccessible and which is provided in particular to supplement and / or support an outer housing.
