Das Verriegelungselement kommt insbesondere beim Durchführen einer Pyrolysefunktion zum Einsatz. Die Aktoreinheit ist dazu vorgesehen, zum Verriegeln der Gargerätetür bei geschlossener Gargerätetür das Verriegelungselement mit einem korrespondierenden Verriegelungselement bzw. mit einer Verriegelungsmuschel der Gargerätetür in Eingriff zu bringen.From the DE 40 40 343 C2 is a device, namely a cooking appliance, with a cooking appliance door, an actuator unit and with a locking element for locking the Gargerätetür known. The locking element is used in particular when performing a pyrolysis function. The actuator unit is provided for locking the cooking appliance door when the cooking appliance door is closed, bringing the locking element into engagement with a corresponding locking element or with a locking cup of the cooking appliance door.

Sowohl aus der US 3 893 554 , sowie aus der DE 29 49 773 A1 ist eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 bekannt, nämlich eine Vorrichtung mit einer Gargerätetür, einer Aktoreinheit und einem Verriegelungselement zum Verriegeln der Gargerätetür, insbesondere beim Durchführen einer Pyrolysefunktion, wobei die Aktoreinheit dazu vorgesehen ist, zum Verriegeln der Gargerätetür bei geschlossener Gargerätetür das Verriegelungselement mit einem korrespondierenden Verriegelungselement der Gargerätetür in Eingriff zu bringen, wobei das Verriegelungselement um eine bei geschlossener Gargerätetür zumindest im Wesentlichen senkrecht zu einer Türebene der Gargerätetür verlaufende Drehachse drehbar ist und einen zumindest im Wesentlichen senkrecht zur Drehachse verlaufenden Verriegelungshaken aufweist, wobei das Verriegelungselement eine Stange umfasst, die einen Abstand zwischen der Aktoreinheit und dem Verriegelungshaken überbrückt.Both from the US 3,893,554 , as well as from the DE 29 49 773 A1 a device according to the preamble of claim 1 is known, namely a device with a cooking appliance door, an actuator unit and a locking element for locking the cooking appliance door, in particular when performing a pyrolysis function, wherein the actuator unit is provided for locking the cooking appliance door with the cooking appliance door closed, the locking element to engage with a corresponding locking element of the cooking appliance door, wherein the locking element is rotatable about a rotation axis running at least substantially perpendicular to a door level of the cooking appliance door with closed cooking appliance door and has a locking hook extending at least substantially perpendicular to the axis of rotation, wherein the locking element comprises a rod that bridges a distance between the actuator unit and the locking hook.

Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung besonders raumsparend und kostengünstig auszugestalten. Die Aufgabe wird gelöst durch eine Vorrichtung mit den Merkmalen des Anspruchs 1. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.The invention is in particular the object of designing a generic device particularly space-saving and cost-effective. The object is achieved by a device having the features of claim 1. Further advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Die Erfindung geht aus von einer Vorrichtung mit einer Gargerätetür, einer Aktoreinheit und mit einem Verriegelungselement zum Verriegeln der Gargerätetür, insbesondere beim Durchführen einer Pyrolysefunktion, wobei die Aktoreinheit dazu vorgesehen ist, zum Verriegeln der Gargerätetür bei geschlossener Gargerätetür das Verriegelungselement mit einem korrespondierenden Verriegelungselement der Gargerätetür in Eingriff zu bringen, wobei das Verriegelungselement um eine bei geschlossener Gargerätetür zumindest im Wesentlichen senkrecht zu einer Türebene der Gargerätetür verlaufende - Drehachse drehbar ist und einen zumindest im Wesentlichen senkrecht zur Drehachse verlaufenden Verriegelungshaken aufweist, wobei das Verriegelungselement eine Stange umfasst, die einen Abstand zwischen der Aktoreinheit und dem Verriegelungshaken überbrückt.The invention is based on a device having a cooking appliance door, an actuator unit and a locking element for locking the cooking appliance door, in particular when carrying out a pyrolysis function, the actuator unit being provided for locking the cooking appliance door with the cooking appliance door closed, the locking element with a corresponding locking element of the cooking appliance door in which the locking element is rotatable about an axis of rotation running at least substantially perpendicular to a door plane of the cooking appliance door when the cooking appliance door is closed and has a locking hook extending at least substantially perpendicularly to the axis of rotation, wherein the locking element comprises a bar which has a spacing between the actuator unit and the locking hook bridged.

Die Aktoreinheit kann in einer dem Fachmann als sinnvoll erscheinenden Weise, beispielsweise als Wachselement, Elektromotor oder Solenoid ausgebildet sein, dessen Bewegung in eine Drehbewegung umgesetzt wird.The actuator unit can be designed in a manner which appears appropriate to a person skilled in the art, for example as a wax element, electric motor or solenoid, whose movement is converted into a rotational movement.

Es wird vorgeschlagen, dass das Verriegelungselement um eine bei geschlossener Gargerätetür zumindest im Wesentlichen senkrecht zu einer Türebene der Gargerätetür verlaufende Drehachse drehbar ist. Dazu kann der zur Realisierung eines axial verschiebbaren Verriegelungselements notwendige Bauraum eingespart werden und insbesondere ein in einem Frontbereich des Gargeräts benötigter Bauraum des Verriegelungselements kann besonders gut ausgenutzt werden. Insbesondere eine Tiefe des für die Bewegungsfreiheit des Verriegelungselements aufzuwendenden Bauraums kann zumindest im Wesentlichen auf die Materialstärke des Verriegelungselements beschränkt werden. Ferner kann in einfacher Weise eine Entkopplung der Aktoreinheit von den auf das Verriegelungselement wirkenden Kräften realisiert werden. Insgesamt können dadurch sowohl die Aktoreinheit als auch das Verriegelungselement im Vergleich zu bekannten Vorrichtungen der gattungsgemäßen Art kostengünstiger ausgestaltet werden.It is proposed that the locking element run around a cooking appliance door closed at least substantially perpendicular to a door level of the cooking appliance door Rotary axis is rotatable. For this purpose, the installation space necessary for the realization of an axially displaceable locking element can be saved, and in particular a space of the locking element required in a front region of the cooking appliance can be utilized particularly well. In particular, a depth of the installation space to be used for the freedom of movement of the locking element can be limited at least essentially to the material thickness of the locking element. Furthermore, a decoupling of the actuator unit from the forces acting on the locking element can be realized in a simple manner. Overall, both the actuator unit and the locking element can be made more cost-effective compared to known devices of the generic type.

Als "zumindest im Wesentlichen senkrecht zu einer Türebene der Gargerätetür verlaufend" soll in diesem Zusammenhang eine Drehachse gelten, deren Winkel zur Türebene in einem Bereich zwischen 70° und 110° liegt, vorzugsweise in einem Bereich zwischen 80° und 100°, so dass eine Komponente einer Bewegung des Verriegelungselements in der Türebene jedenfalls größer ist als eine Komponente senkrecht dazu.As "at least substantially perpendicular to a door level of Gargerätetür running" should apply in this context, a rotation axis whose angle to the door level is in a range between 70 ° and 110 °, preferably in a range between 80 ° and 100 °, so that a In any case, the component of a movement of the locking element in the door plane is greater than a component perpendicular thereto.

In der Erfindung wird vorgeschlagen, dass das Verriegelungselement einen zumindest im Wesentlichen senkrecht zur Drehachse verlaufenden Verriegelungshaken aufweist. Dadurch kann konstruktiv einfach ein Formschluss zwischen dem Verriegelungselement in seiner Verriegelungskonfiguration und der Gargerätetür erreicht werden.In the invention it is proposed that the locking element has an at least substantially perpendicular to the axis of rotation extending locking hook. As a result, a positive connection between the locking element in its locking configuration and the cooking appliance door can be achieved structurally.

Die Aktoreinheit kann an einer beinahe beliebigen Stelle des Gargeräts angeordnet werden, wenn das Verriegelungselement eine Stange umfasst, die einen Abstand zwischen der Aktoreinheit und dem Verriegelungshaken überbrückt. Dadurch kann ein Bauraum innerhalb des Gargeräts besonders gut genutzt werden.The actuator unit can be arranged at an almost arbitrary point of the cooking appliance, when the locking element comprises a rod which bridges a distance between the actuator unit and the locking hook. As a result, a space within the cooking appliance can be used particularly well.

Die Aktoreinheit kann vor auf einen vorderen Bereich des Verriegelungselements wirkenden Verriegelungskräften wirkungsvoll abgeschirmt werden, wenn die Stange drehbar und axial fest in einem Führungslager an einem Gargerätekörper gelagert ist. Die Lagerung kann beispielsweise über eine Nut in der Stange oder über einen in eine solche Nut eingreifenden Lagerungsring erfolgen.The actuator unit can be effectively shielded from acting on a front portion of the locking element locking forces when the rod is rotatably and axially fixedly mounted in a guide bearing on a cooking appliance body. The storage can be done for example via a groove in the rod or via an engaging in such a groove storage ring.

Die Aktoreinheit kann in konstruktiv einfacher Weise entfernt von einer Bedienblende und einer Steuereinheit des Gargeräts angeordnet werden, wenn der Abstand zwischen der Aktoreinheit und dem Verriegelungshaken wenigstens 20 cm beträgt. Die erfindungsgemäße Verriegelungsvorrichtung kann dadurch insbesondere ohne wesentliche bauliche Änderungen im Zusammenhang mit bekannten Bedienblenden bzw. einer Steuerelektronik verwendet werden, da nur eine schmale Öffnung zum Durchgriff der Stange notwendig ist.The actuator unit can be arranged in a structurally simple manner away from a control panel and a control unit of the cooking appliance, if the distance between the actuator unit and the locking hook is at least 20 cm. The locking device according to the invention can be used in particular without significant structural changes in connection with known control panels or control electronics, since only a narrow opening for the passage of the rod is necessary.

Eine kostengünstige und konstruktiv einfache Verriegelungsvorrichtung kann dadurch realisiert werden, dass das korrespondierende Verriegelungselement der Gargerätetür als Ausnehmung in einer seitlichen Randfläche der Gargerätetür ausgebildet ist.An inexpensive and structurally simple locking device can be realized in that the corresponding locking element of the cooking appliance door is formed as a recess in a lateral edge surface of the cooking appliance door.

Ist die Gargerätetür um eine entlang einem ersten Rand verlaufende Schwenkachse schwenkbar und ist das korrespondierende Verriegelungselement an einem dem ersten Rand gegenüberliegenden seitlichen Rand der Gargerätetür angeordnet, kann erreicht werden, dass das Verriegelungselement eine optimale Hebelwirkung ausnutzt. Dadurch können das Verriegelungselement und das korrespondierende Verriegelungselement kostengünstig auf eine im Vergleich zu einer Anordnung im Bereich der Schwenkachse geringere Verriegelungskraft ausgelegt werden.If the cooking appliance door is pivotable about a pivot axis extending along a first edge and if the corresponding locking element is arranged on a side edge of the cooking appliance door opposite the first edge, it can be achieved that the locking element takes advantage of optimum leverage. As a result, the locking element and the corresponding locking element can be inexpensively designed for a lower locking force compared to an arrangement in the region of the pivot axis.

Weist das korrespondierende Verriegelungselement eine Anschlagfläche zum Begrenzen einer Drehbewegung des Verriegelungselements auf, kann auf eine Begrenzung der Drehbewegung in der Lagerung des Verriegelungselements verzichtet werden. Ferner kann eine definierte, reproduzierbare Verriegelungsposition gewährleistet werden, die das Verriegelungselement immer dann erreicht, wenn das korrespondierende Verriegelungselement nicht verschmutzt ist.If the corresponding locking element has a stop surface for limiting a rotational movement of the locking element, it is possible to dispense with a limitation of the rotational movement in the mounting of the locking element. Furthermore, a defined, reproducible locking position can be ensured, which always reaches the locking element when the corresponding locking element is not dirty.

Ein an die Schwenkbewegung des Verriegelungshakens angepasstes korrespondierendes Verriegelungselement kann dadurch erreicht werden, dass das korrespondierende Verriegelungselement der Gargerätetür zumindest eine Begrenzungsfläche aufweist, die bei geschlossener Gargerätetür einen Ausschnitt einer bezüglich der Drehachse des Verriegelungselements achssymmetrischen Mantelfläche bildet. Besonders vorteilhaft sind Ausgestaltungen der Erfindung, in denen das korrespondierende Verriegelungselement die Form eines Kreissegments hat, insbesondere die Form eines Viertelkreises. Dann kann nämlich eine radiale Begrenzungsfläche des korrespondierenden Verriegelungselements als Anschlagfläche genutzt werden.A corresponding locking element adapted to the pivoting movement of the locking hook can be achieved in that the corresponding locking element of the cooking appliance door has at least one boundary surface which, when the cooking appliance door is closed, forms a section of a lateral surface which is axisymmetric with respect to the axis of rotation of the locking element. Particularly advantageous embodiments of the invention, in which the corresponding locking element has the shape of a circle segment, in particular the shape of a quarter circle. Then Namely, a radial boundary surface of the corresponding locking element can be used as a stop surface.

Eine Überlastung des Aktors bei einer Blockade des Verriegelungselements wird vermieden, wenn das Verriegelungselement über ein Torsionsfederelement mit der Aktoreinheit verbunden ist.An overload of the actuator in a blockade of the locking element is avoided when the locking element is connected via a torsion spring element with the actuator unit.

Da das Torsionsfederelement von der Stange zwischen der Aktoreinheit und dem Verriegelungshaken gebildet wird, werden Kosten eingespart und eine Bauteilvielfalt reduziert.Since the torsion spring element is formed by the rod between the actuator unit and the locking hook, costs are saved and a diversity of components is reduced.

Umfasst die Vorrichtung zumindest ein Sensorelement zum Erfassen einer Stellung des Verriegelungselements, kann die Verriegelung sicher gewährleistet werden und eine Verbrennungsgefahr für einen Bediener kann reduziert werden. Ferner kann aus der Tatsache, dass das Verriegelungselement seine Verriegelungsposition trotz der entsprechenden Aktivität der Aktoreinheit nicht erreicht, auf eine Verschmutzung des korrespondierenden Verriegelungselements in der Gargerätetür geschlossen werden. Ist dies der Fall, kann eine Steuereinheit des Gargeräts zur Vermeidung von Gefahren die Pyrolysefunktion blockieren und gegebenenfalls den Bediener zur Reinigung des korrespondierenden Verriegelungselements auffordern.If the device comprises at least one sensor element for detecting a position of the locking element, the locking can be reliably ensured and a risk of burns for an operator can be reduced. Furthermore, from the fact that the locking element does not reach its locking position despite the corresponding activity of the actuator unit, contamination of the corresponding locking element in the cooking appliance door can be concluded. If this is the case, a control unit of the cooking appliance can block the pyrolysis function to avoid dangers and, if necessary, prompt the operator to clean the corresponding locking element.

Eine unvollständige Verriegelung kann ausgeschlossen werden, wenn die Vorrichtung neben dem Sensorelement zum Erfassen der Stellung des Verriegelungselements zumindest ein weiteres Sensorelement zum Erfassen einer Stellung der Gargerätetür umfasst. Das weitere Sensorelement kann beispielsweise kostengünstig und robust als Reed-Schalter ausgebildet sein.An incomplete locking can be excluded if the device comprises at least one further sensor element for detecting a position of the cooking appliance door in addition to the sensor element for detecting the position of the locking element. The further sensor element can be designed, for example, inexpensively and robustly as a reed switch.

Eine universell einsetzbare Verriegelungsvorrichtung ist erreichbar, wenn das Verriegelungselement und das Sensorelement bezüglich ihrer Einbauposition austauschbar sind. Es kann insbesondere eine Haltevorrichtung für ein solches Sensorelement zum Halten des Verriegelungselements genutzt werden, wodurch ein konstruktiver Aufwand reduziert werden kann. Insbesondere bei um eine vertikale Schwenkachse schwenkbaren Gargerätetüren kann durch die Austauschbarkeit der Verriegelungsvorrichtung und des Sensorelements sichergestellt werden, dass das Verriegelungselement stets an einer hinsichtlich der Hebelwirkung vorteilhaften Seite eines oberen oder unteren Rands der Gargerätetür angeordnet ist.A universally usable locking device can be achieved if the locking element and the sensor element with respect to their installation position are interchangeable. It can be used in particular a holding device for such a sensor element for holding the locking element, whereby a constructive effort can be reduced. In particular, when it comes to pivoting about a vertical pivot axis cooking appliance doors can be ensured by the interchangeability of the locking device and the sensor element, that the locking element always at a respect the lever effect advantageous side of an upper or lower edge of the cooking appliance door is arranged.

Ist die Aktoreinheit dazu vorgesehen, in einer bezüglich einer von der Gargerätetür verschließbaren Garraumöffnung hinteren Hälfte eines die Gargerätetür umfassenden Gargeräts angeordnet zu sein, kann der im Allgemeinen nur sehr beschränkt verfügbare Bauraum in der vorderen Hälfte des Gargeräts vorteilhaft für andere Zwecke genutzt werden. Weitere Vorteile ergeben sich aus der folgenden Figurenbeschreibung. Die Figuren zeigen ein Ausführungsbeispiel der Erfindung. Die Figuren, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination, die der Fachmann auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen wird.If the actuator unit is provided to be arranged in a rear half of a cooking appliance comprising the cooking appliance door opening, which can be closed by the cooking appliance door, the generally very limited available installation space in the front half of the cooking appliance can advantageously be used for other purposes. Further advantages will become apparent from the following description of the figures. The figures show an embodiment of the invention. The figures, the description and the claims contain numerous features in combination which the skilled person will also consider individually and summarize to meaningful further combinations.

Figur 1 zeigt ein als Haushaltsbackofen mit Pyrolysefunktion ausgebildetes Gargerät mit einer Gargerätetür 10, einer Aktoreinheit 12 und mit einem Verriegelungselement 14 zum Verriegeln der Gargerätetür 10. Das Verriegelungselement 14 dient dazu, die Gargerätetür 10, insbesondere beim Durchführen der Pyrolysefunktion, zu verriegeln, wobei die Aktoreinheit 12 dazu vorgesehen ist, zum Verriegeln der Gargerätetür 10 bei geschlossener Gargerätetür 10 das Verriegelungselement 14 mit einem korrespondierenden Verriegelungselement 15 bzw. mit einer Verriegelungsmuschel der Gargerätetür 10 in Eingriff zu bringen. FIG. 1 shows a cooking appliance designed as a household oven with a pyrolysis function with a cooking appliance door 10, an actuator unit 12 and with a locking element 14 for locking the cooking appliance door 10. The locking element 14 serves to lock the cooking appliance door 10, in particular when performing the pyrolysis function, the actuator unit 12 is provided for locking the cooking appliance door 10 with the cooking appliance door 10, the locking element 14 with a corresponding locking element 15 or with a locking shell of Gargerätetür 10 into engagement.

Das Verriegelungselement 14 ist mit Hilfe der Aktoreinheit 12 um eine Drehachse 16 drehbar, die bei geschlossener Gargerätetür 10 senkrecht zu einer Türebene und bei aufgestelltem Gargerät horizontal oberhalb eines Garraums verläuft.The locking element 14 is rotatable about the axis of rotation 16 with the aid of the actuator unit 12, which extends horizontally above a cooking chamber when the cooking appliance door 10 is perpendicular to a door level and when the cooking appliance is set up.

Das Verriegelungselement 14 umfasst eine Stange 18 und einen senkrecht zur Drehachse 16 verlaufenden Verriegelungshaken 20. Die Stange 18 überbrückt einen Abstand von wenigstens 20 cm zwischen der Aktoreinheit 12 und dem Verriegelungshaken 20. Der Verriegelungshaken 20 steht rechtwinklig von der Stange 18 ab. Die Stange 18 ist drehbar und axial fest in einem Führungslager 22 an einem Gargerätekörper des Gargeräts gelagert. Das Führungslager 22 schirmt alle im Bereich des Verriegelungshakens 20 auf das Verrieglungselement 14 wirkenden Kräfte von der Aktoreinheit 12 ab, so dass diese auch durch ein Zerren an der Gargerätetür 10 nicht beschädigt werden kann.The locking element 14 comprises a rod 18 and a perpendicular to the axis of rotation 16 extending locking hook 20. The rod 18 bridges a distance of at least 20 cm between the actuator unit 12 and the locking hook 20. The locking hook 20 is perpendicular from the rod 18 from. The rod 18 is rotatably and axially fixedly mounted in a guide bearing 22 on a cooking appliance body of the cooking appliance. The guide bearing 22 shields all forces acting on the locking element 14 in the region of the locking hook 20 from the actuator unit 12 so that they can not be damaged by tugging on the cooking device door 10.

Das korrespondierende Verriegelungselement 15 der Gargerätetür 10 ist als muschelförmige Ausnehmung bzw. als Verriegelungsmuschel in einer seitlichen Randfläche 24 der Gargerätetür 10 ausgebildet, die in einer Ansicht senkrecht zur Gargerätetür 10 die Form eines Viertelkreises hat (Figur 5).The corresponding locking element 15 of the cooking appliance door 10 is formed as a shell-shaped recess or as a locking shell in a lateral edge surface 24 of the cooking appliance door 10 which has the shape of a quarter circle in a view perpendicular to the cooking appliance door ( FIG. 5 ).

Die Gargerätetür 10 ist über zwei hier nicht explizit dargestellte Scharniere um eine entlang einem ersten, unteren Rand verlaufende Schwenkachse 26 schwenkbar. Das korrespondierende Verriegelungselement 15 ist an einem dem ersten Rand gegenüberliegenden oberen seitlichen Rand der Gargerätetür 10 angeordnet (Figur 4).The cooking appliance door 10 is pivotable about two hinges not explicitly shown here about a pivot axis 26 extending along a first, lower edge. The corresponding locking element 15 is arranged on an upper edge opposite the first edge of the cooking appliance door 10 ( FIG. 4 ).

Eine radiale, senkrecht zur Schwenkachse 26 der Gargerätetür 10 ausgerichtete Begrenzungsfläche 30 des korrespondierenden Verriegelungselements 15 bildet eine Anschlagfläche 28 zum Begrenzen einer Drehbewegung des Verriegelungselements 14.A radial, perpendicular to the pivot axis 26 of the cooking appliance door 10 aligned boundary surface 30 of the corresponding locking element 15 forms a stop surface 28 for limiting a rotational movement of the locking element fourteenth

Eine weitere Begrenzungsfläche 30 des korrespondierenden Verriegelungselements 15 bildet bei geschlossener Gargerätetür 10 einen Ausschnitt einer bezüglich der Drehachse 16 des Verriegelungselements 14 achssymmetrischen Mantelfläche, und zwar einen Ausschnitt einer Zylindermantelfläche.A further boundary surface 30 of the corresponding locking element 15 forms with closed cooking appliance door 10 a section of an axis of symmetry with respect to the axis of rotation 16 of the locking element 14, namely a section of a cylinder jacket surface.

Die Stange 18, über die das Verriegelungselement 14 bzw. der Verriegelungshaken 20 mit der Aktoreinheit 12 verbunden ist, bildet ein Torsionsfederelement 32. Ist die Gargerätetür 10 beispielsweise nicht vollständig geschlossen oder ist das korrespondierende Verriegelungselement 15 der Gargerätetür 10 verschmutzt, kann der Verriegelungshaken 20 die Anschlagfläche 28 nicht erreichen. Durch die Torsion der Stange 18 bzw. des Torsionsfederelements 32 bleibt die Belastung der Aktoreinheit 12 dennoch in einem zulässigen Rahmen und eine Beschädigung der Aktoreinheit 12 durch Heißlaufen oder Ähnliches kann vermieden werden.The rod 18, via which the locking element 14 and the locking hook 20 is connected to the actuator unit 12, forms a Torsionsfederelement 32. If the cooking appliance door 10, for example, not completely closed or the corresponding locking element 15 of the cooking appliance door 10 is dirty, the locking hook 20 can Do not reach stop surface 28. By the torsion of the rod 18 and the Torsionsfederelements 32, the load of the actuator unit 12 still remains within a permissible range and damage to the actuator unit 12 by hot running or the like can be avoided.

Dreht das Verriegelungselement 14 mit dem Verriegelungshaken beim Aktivieren der Verriegelung über die durch die Anschlagfläche 28 definierte Verriegelungsposition hinaus, so ist das korrespondierende Verriegelungselement 15 nicht in der Verriegelungsposition vorhanden, weil z.B. die Gargerätetür 10 nicht vollständig geschlossen ist.If the locking element 14 with the locking hook rotates beyond the locking position defined by the stop surface 28 when the lock is activated, then the corresponding locking element 15 is not present in the locking position because e.g. the cooking appliance door 10 is not completely closed.

Das Gargerät umfasst ein Sensorelement 34 zum Erfassen einer Stellung des Verriegelungselements 14, durch welches eine zentrale Steuereinheit erkennen kann, ob sich das Verriegelungselement 14 in der Verriegelungsposition befindet. Letzteres ist eine notwendige Bedingung für die Verriegelung der Gargerätetür 10.The cooking appliance comprises a sensor element 34 for detecting a position of the locking element 14, by means of which a central control unit can detect whether the locking element 14 is in the locking position. The latter is a necessary condition for the locking of the cooking appliance door 10.

Zudem hat das Gargerät ein weiteres als Reed-Schalter ausgebildetes Sensorelement 36 zum Erfassen einer Stellung der Gargerätetür 10. Dadurch kann die Steuereinheit zudem eine hinreichende Bedingung für die Verriegelung der Gargerätetür 10 erfassen. Nur wenn das Verriegelungselement 14 sich in der Verriegelungsposition befindet und gleichzeitig die Gargerätetür 10 vollständig geschlossen ist, besteht ein sicherer Formschluss und die Gargerätetür 10 kann nicht mehr geöffnet werden. Erst wenn diese Bedingungen erfüllt sind, startet die Steuereinheit einen Pyrolysevorgang.In addition, the cooking appliance has another designed as a reed switch sensor element 36 for detecting a position of the cooking appliance door 10. This allows the control unit also detect a sufficient condition for the locking of the cooking appliance door 10. Only when the locking element 14 is in the locking position and at the same time the cooking appliance door 10 is fully closed, there is a positive fit and the cooking appliance door 10 can not be opened. Only when these conditions are met does the control unit start a pyrolysis process.

Das Verriegelungselement 14 und das weitere Sensorelement 36 zum Erfassen einer Stellung der Gargerätetür 10 durchgreifen jeweils gleichartige Ausnehmungen 38, 40 in einem Frontblech einer Muffel 42 des Gargeräts. Beide Einheiten sind daher bezüglich ihrer Einbauposition austauschbar.The locking element 14 and the further sensor element 36 for detecting a position of the cooking appliance door 10 each engage through similar recesses 38, 40 in a front plate of a muffle 42 of the cooking appliance. Both units are therefore interchangeable with respect to their installation position.

Die Aktoreinheit 12 selbst ist oberhalb der Muffel 42 in einer bezüglich einer von der Gargerätetür 10 verschließbaren Garraumöffnung hinteren Hälfte des Gargeräts angeordnet.Actuator unit 12 itself is arranged above muffle 42 in a rear half of the cooking appliance with respect to a cooking chamber opening which can be closed by cooking appliance door 10.

Der Bauraum in der vorderen Hälfte des Gargeräts bleibt dadurch frei für andere Baugruppen, die unmittelbar über eine Bedienblende 44 des Gargeräts betätigbar sind und daher in unmittelbarer Nähe der letzteren angeordnet werden sollten, um eine kompakte Baugruppe zu bilden.The space in the front half of the cooking appliance remains free for other assemblies that are directly operable via a control panel 44 of the cooking appliance and should therefore be placed in the immediate vicinity of the latter to form a compact assembly.
