Description

Beschreibung Schaltvorrichtung und Anordnung zur Erfassung unterschiedlicher Positionen eines Türelements Description switching device and arrangement for detecting different positions of a door element
[001] Die vorliegende Erfindung betrifft eine Schaltvorrichlung, insbesondere einen Türkontaktschalter gemäß dem Oberbegriff des Patentanspruchs 1. Die Erfindung betrifft weiterhin eine Anordnung zur Erfassung unterschiedlicher Positionen eines Türelements gemäß dem Oberbegriff des Anspruchs 6. Weiterhin betrifft die Erfindung ein Haushaltsgerät gemäß dem Oberbegriff des Patentanspruchs 11.The present invention relates to a switching device, in particular a door contact switch according to the preamble of claim 1. The invention further relates to an arrangement for detecting different positions of a door element according to the preamble of claim 6. Furthermore, the invention relates to a household appliance according to the preamble of claim 11th
[002] Bei elektrischen Haushaltsgeräten kann eine Funktion vorgesehen sein, die beim Öffnen einer Tür eine Innenraumbeleuchlung und/oder andere elektrische Verbraucher ein- oder ausschaltet. Diese Funktion wird zweckmäßigerweise mittels eines sog. Türkontaktschalters ausgelöst, da dieser je nach Öffnungsstellung der Tür ein zuverlässiges Schaltsignal zur Verfügung stellen kann. Derartige Türkontaktschalter umfassen meist ein gegen die Kraft einer Feder verschiebbares Stellglied, das in Wirkverbindung mit einem elektrischen Schalter steht. Wird die Tür aus ihrer geschlossenen Stellung in eine geöffnete Stellung gebracht, wird das Stellglied, bspw. ein Stößel, der durch Federkraft verschoben werden kann, betätigt. Hierdurch wird der Schalter ausgelöst und liefert gegenüber der gedrückten Stellung des Stößels ein anderes Schaltsignal. Derartige Türkontaktschalter dienen bei Hihlschränken dem Einschalten einer Innenraumbeleuchlung und können bei Gargeräten eine Garraumbeleuchtung aktivieren, sobald eine Backofentür geöffnet wird.In the case of electrical household appliances, a function can be provided which switches an interior lighting and / or other electrical consumers on or off when a door is opened. This function is expediently triggered by a so-called door contact switch, since this can provide a reliable switching signal depending on the opening position of the door. Such door contact switches usually comprise an actuator which can be displaced against the force of a spring and which is operatively connected to an electrical switch. If the door is moved from its closed position into an open position, the actuator, for example a plunger, which can be moved by spring force, is actuated. This triggers the switch and delivers a different switching signal compared to the depressed position of the plunger. Such door contact switches are used in refrigerator cabinets to switch on interior lighting and can activate cooking space lighting in cooking appliances as soon as an oven door is opened.
[003] Unter Umständen kann es wünschenswert sein, auf ein Einschalten der Innenraum- bzw. der Garraumbeleuchtung beim Öffnen der Tür zu verzichten. Eine solche Funktion ist als sog. Sabbat-Schaltung bekannt, die ein Einschalten einer Beleuchtung beim Öffnen der Backofentür verhindert. Ein solcher Sabbat-Modus kann aus religiösen Gründen wünschenswert bzw. erforderlich sein. Verfahren und Vorrichtungen zum Betrieb von Gargeräten mit einem sog. Sabbat-Modus sind u.a. aus der US 58 08 278 und aus der US 60 66 837 bekannt. Hierbei wird mittels elektronischer Schaltungen eine manuelle Einflussnahme auf bestimmte Funktionen des Gargeräts während bestimmter definierbarer Zeiträume verhindert.Under certain circumstances, it may be desirable to forego switching on the interior or cooking space lighting when the door is opened. Such a function is known as the so-called Sabbath circuit, which prevents the lighting from being switched on when the oven door is opened. Such a Sabbath mode may be desirable or necessary for religious reasons. Methods and devices for operating cooking devices with a so-called Sabbath mode include known from US 58 08 278 and from US 60 66 837. In this case, manual influence on certain functions of the cooking device is prevented during certain definable periods by means of electronic circuits.
[004] Eine Aufgabe der vorliegenden Erfindung besteht darin, auf einfache Weise eine mechanische Schaltfiinktion beim Öffnen eines Türelements eines elektrischen Hausgeräts beeinflussen zu können.An object of the present invention is to be able to influence a mechanical switching function when opening a door element of an electrical household appliance in a simple manner.
[005] Diese Aufgabe wird bei einer Schalteinrichtung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 dadurch gelöst, dass eine Wirkverbindung zwischen einem mechanischen Schaltelement und einem von diesem betätigbaren elektrischen Schalter trennbar ist. Die erfindungsgemäße Schalteinrichtung ermöglicht es somit, eine elektrische Schaltfiinktion, die normalerweise von dem Schaltelement ausgelöst wird, je nach Bedarf zu deaktivieren. Eine solche Schaltfiinktion kann beispielsweise bei einem Gargerät eine durch Öffnen einer Backofentür einschaltbare Garraumbeleuchtung sein. Die elektrische Schaltfiinktion kann beispielsweise auch die Abschaltung eines elektrischen Heißluftgebläses einer Offenmuffel eines Gargeräts bewirken, wenn eine Tür zum Garraum geöffnet wird. Die Ein- und Ausschaltfiinktion für die Garraumbeleuchtung und/oder für weitere Verbraucher ist auf diese Weise mittels einer Trennung der Wirkverbindung zwischen Schaltelement und elektrischem Schalter deaktivierbar.[005] This object is achieved with a switching device with the features of The preamble of claim 1 is achieved in that an operative connection between a mechanical switching element and an electrical switch actuable by it can be separated. The switching device according to the invention thus makes it possible to deactivate an electrical switching function, which is normally triggered by the switching element, as required. Such a switching function can be, for example in a cooking appliance, a cooking space lighting which can be switched on by opening an oven door. The electrical switching function can, for example, also switch off an electric hot air blower of an open muffle of a cooking appliance when a door to the cooking space is opened. The switch-on and switch-off function for the cooking space lighting and / or for other consumers can be deactivated in this way by separating the operative connection between the switching element and the electrical switch.
[006] Mittels der erfindungsgemäßen Schalteinrichtung können die unterschiedlichsten Schaltfimktionen ausgelöst werden. Die Schaltfiinktion kann bei einem elektrischen Kühlgerät bspw. das Einschalten einer Innenraumbeleuchtung beim Öffnen einer Fronttür bewirken. Die auftrennbare Wirkverbindung zwischen dem Schaltelement und dem elektrischen Schalter kann dazu führen, dass die Innenraumbeleuchlung nicht mehr eingeschaltet wird, sobald die Tür geöffnet wird.[006] A wide variety of switching functions can be triggered by means of the switching device according to the invention. The switching function in an electrical cooling device can, for example, cause the interior lighting to be switched on when a front door is opened. The separable active connection between the switching element and the electrical switch can result in the interior lighting no longer being switched on as soon as the door is opened.
[007] Ein besonderer Vorteil der mechanisch deaktivierbaren Schaltfiinktion liegt darin, dass sich mit Hilfe der erfindungsgemäßen Schalteinrichtung elektrische Haushaltsgeräte zur Verfügung stellen lassen, die eine sog. Sabbat-Funktion aufweisen bzw. ermöglichen. Da es manche Reügionen nicht erlauben, während bestimmter Zeiträume - bspw. während des Sabbats - nach Einbruch der Dämmerung eine elektrische Beleuchtung einzuschalten, kann das Problem entstehen, dass ein Gargerät, das über eine Schaltfiinktion zum Einschalten einer Garraumbeleuchtung beim Öffnen der Backofentür verfügt, während des Sabbats nicht mehr verwendet werden kann. Ansonsten könnte es bspw. passieren, dass ein Garvorgang vor Einbruch der Dämmerung begonnen wurde und darüber hinaus andauert. Ein Öffnen der Backofentür wäre dann nicht mehr möglich, ohne zuvor das Gerät abzuschalten. Ein Wiedereinschalten des Geräts zum Fertiggaren wäre jedoch ebenfalls nicht mehr möglich, da auch dies während des Sabbats untersagt ist. Die erfindungsgemäße Schalteinrichtung ermöglicht es nun auf einfache und kostengünstige Weise, alle derartigen Schaltfiinktionen durch Auftrennung der Wirkverbindung zwischen dem Schaltelement und dem elektrischen Schalter zu deaktivieren, bevor der Garvorgang begonnen wird. [008] Grundsätzlich eignet sich die erfindungsgemäße Schalteinrichtung zum Einbau in alle elektrischen Geräte, bei denen das Öffnen einer Tür eine Schaltfiinktion auslösen soll. Auch Hihlschränke oder Gefriertruhen können auf diese Weise mit einer Sabbat- Funktion versehen werden, bei der das Licht grundsätzlich abgeschaltet bleibt, auch wenn die Tür geöffnet wird. Darüber hinaus können bei vielen anderen Hausgeräten Schaltfiinktionen deaktiviert werden, die mit einer Öffnung eines Türelements verbunden sind. [009] Wahlweise kann das Schaltelement zwischen seinen wenigstens zwei Betriebspositionen eine im Wesentlichen translatorische oder auch eine rotatorische Bewegung ausführen. Bei einer translatorischen Bewegung des Schaltelements kann dieses vorzugsweise ein gegen Federkraft linear verschiebbarer Stößel sein, der durch einen Kontakt mit dem Türelement verschoben wird. Das Türelement kann insbesondere eine offenbare Gehäuseklappe des Hausgeräts sein, bspw. eine Fronttür bzw. Frontklappe eines Garraumes eines Gargeräts oder auch eine Kuhlschranktür o. dgl. Die Schalteinrichtung bildet auf diese Weise einen Türkontaktschalter, bestehend aus einem Schalter, einer Feder, einem Gehäuse sowie einem Stößel, die in Zusammenwirkung die Position der Tür auswerten.A particular advantage of the mechanically deactivatable switching function is that electrical switching devices which have or enable a so-called Sabbath function can be made available with the switching device according to the invention. Since some regions do not allow you to switch on electrical lighting after dusk during certain periods - e.g. during the Sabbath - the problem may arise that a cooking appliance that has a switching function to switch on the lighting when opening the oven door while of the Sabbath can no longer be used. Otherwise it could happen, for example, that a cooking process was started before dusk and continued beyond. It would then no longer be possible to open the oven door without first switching off the appliance. However, it would also no longer be possible to switch the appliance on again for ready cooking, as this is also prohibited during the Sabbath. The switching device according to the invention now makes it possible, in a simple and inexpensive manner, to deactivate all such switching functions by disconnecting the operative connection between the switching element and the electrical switch before the cooking process is started. Basically, the switching device according to the invention is suitable for installation in all electrical devices in which the opening of a door is intended to trigger a switching function. Fridges and freezers can also be equipped with a Sabbath function in this way, in which the light remains switched off even when the door is opened. In addition, switching functions that are connected to an opening of a door element can be deactivated in many other household appliances. Optionally, the switching element between its at least two operating positions can perform an essentially translational or a rotational movement. In the case of a translational movement of the switching element, this can preferably be a plunger which can be displaced linearly against spring force and which is displaced by contact with the door element. The door element can in particular be an openable housing flap of the domestic appliance, for example a front door or front flap of a cooking space of a cooking appliance or a refrigerator door or the like. The switching device in this way forms a door contact switch, consisting of a switch, a spring, a housing and a plunger, which work together to evaluate the position of the door.
[010] Der elektrische Schalter kann wahlweise auf direkte Weise einen Kontakt schließen oder aber auch eine nachgeordnete elektrische bzw. elektronische Einheit ansteuern. Bei geöffnetem oder zumindest teilweise geöffnetem Türelement ist das Schaltelement bzw. der Stößel durch Einwirkung der Federkraft in seine erste Betriebslage geschoben, welche somit eine Ruhelage darstellt. Bei geschlossenem Türelement ist das Schaltelement bzw. der Stößel in seine zweite Betriebsposition gedrückt. Der elektrische Schalter kann insbesondere einen verschiebbaren Schaltstift ausweisen, der von einem Nocken am Außenumfang des verschiebbaren Stößels betätigbar ist.The electrical switch can either close a contact in a direct manner or can also control a downstream electrical or electronic unit. When the door element is open or at least partially open, the switching element or the plunger is pushed into its first operating position by the action of the spring force, which therefore represents a rest position. When the door element is closed, the switching element or the plunger is pressed into its second operating position. The electrical switch can in particular have a displaceable switching pin which can be actuated by a cam on the outer circumference of the displaceable plunger.
[011] In einer ersten Ausführungsform der Erfindung kann der Stößel um seine Längsachse drehbar ausgeführt sein, so dass die Wirkverbindung zwischen dem Schaltelement und dem elektrischen Schalter mittels Drehen des Stößels um einen bestimmten Winkel trennbar ist. Der Nocken am Außenumfang des verschiebbaren Stößels darf daher nicht den gesamten Umfang des Stößels beschreiben, sondern nur ein Umfangssegment, so dass durch einfaches Drehen des Stößels die Wirkverbindung zwischen dem betätigbaren Schaltstift des Schalters und dem verschiebbaren Stößel aufgetrennt wird. Mittels einer einfachen Drehung des Stößels kann somit ein Benutzer die Türabfrage aktiv oder passiv schalten.In a first embodiment of the invention, the plunger can be made rotatable about its longitudinal axis, so that the operative connection between the switching element and the electrical switch can be separated by rotating the plunger by a certain angle. The cam on the outer circumference of the displaceable plunger must therefore not describe the entire circumference of the plunger, but only one circumferential segment, so that the operative connection between the actuatable switching pin of the switch and the displaceable plunger is broken by simply rotating the plunger. With a simple rotation of the ram, a user can switch the door query active or passive.
[012] Eine vorteilhafte Variante kann vorsehen, dass am Außenumfang des Stößels zwei oder mehr Nocken vorgesehen sind, so dass durch ein jeweiliges Drehen des Stößels um einen Winkel von bspw. ca. 90 Grad eine Aktivierung bzw. Deaktivierung des Türkontaktschalters ermöglicht ist. Diese mindestens vier verschiedenen Winkelstellungen des Stößels werden vorzugsweise durch ein geeignetes Rastelement definiert, das ein unbeabsichtigtes Verdrehen des Stößels verhindern kann.An advantageous variant can provide that two on the outer circumference of the plunger or more cams are provided, so that activation or deactivation of the door contact switch is made possible by rotating the plunger through an angle of, for example, approximately 90 degrees. These at least four different angular positions of the plunger are preferably defined by a suitable latching element which can prevent the plunger from being inadvertently rotated.
[013] Eine erfindungsgemäße Anordnung zur Erfassung mindestens zweier unterschiedlicher Positionen eines beweglichen Türelements mit den Merkmalen des Patentanspruchs 6 sieht vor, dass eine Wii-kverbindung zwischen dem Türelement und der erfindungsgemäßen Schalteinrichtung trennbar ist. Bei dieser Anordnung kann der Stößel bspw. durch Verschieben oder Versenken aus dem Eingriffsbereich des Türelements gebracht werden. Der Stößel kann wahlweise auch mittels einer Kulissenmechanik - ähnlich einer Kugelschreibermechanik - versenkbar und damit aus dem Eingriffsbereich des Türelements bringbar sein. Durch das Versenken des Stößels erreicht die Tür im geschlossenen Zustand den Stößel nicht mehr. Die normalerweise mit einer Verschiebung des Stößels aus seiner ersten Betriebsposition in die zweite Betriebsposition auslösbare Schaltfiinktion wird nicht mehr ausgelöst. Durch das Freigeben des Stößels durch den Benutzer erreicht die Tür im geschlossenen Zustand den Stößel wieder. Die damit auslösbare Schaltfiinktion wird wieder ausgelöst.An arrangement according to the invention for detecting at least two different positions of a movable door element with the features of claim 6 provides that a Wii-k connection between the door element and the switching device according to the invention can be separated. In this arrangement, the plunger can be brought out of the engagement area of the door element, for example, by moving or countersinking it. The plunger can optionally also be countersunk by means of a link mechanism - similar to a ballpoint pen mechanism - and can thus be brought out of the engagement area of the door element. When the plunger is lowered, the door no longer reaches the plunger when it is closed. The switching function that can normally be triggered by moving the plunger from its first operating position to the second operating position is no longer triggered. When the ram is released by the user, the door reaches the ram again when it is closed. The switching function that can be triggered is triggered again.
[014] Eine alternative Variante sieht vor, dass die Wirkverbindung zwischen der Schalteinrichtung und dem Türelement mittels Freigabe einer im Türelement angeordneten Mulde zur Aufnahme des Stößels trennbar ist. Die Mulde kann bspw. mittels eines Schiebers freigegeben werden, so dass der Stößel bei geschlossenem Türelement und bei geöffnetem Schieber in die hiervon freigegebene Mulde eintauchen kann.An alternative variant provides that the operative connection between the switching device and the door element can be separated by releasing a trough arranged in the door element for receiving the tappet. The trough can be released, for example, by means of a slide, so that the plunger can dip into the trough released when the door element is closed and when the slide is open.
[015] Die Erfindung hat den Vorteil, dass der Benutzer des elektrischen Gerätes selbst bestimmen kann, ob die Erkennung der Türendlage eingeschaltet ist oder nicht. Hiermit kann er auch direkten Einfluss auf verschiedene Funktionen nehmen, die mit dieser Türabfrage gekoppelt sind. Dies kann beispielsweise das Ein- und Ausschalten einer Beleuchtung, einer Energieeinsparung, einer Heizung oder eines Heißluftgebläsemotors oder dergleichen sein.The invention has the advantage that the user of the electrical device can determine whether the detection of the door end position is switched on or not. It can also have a direct impact on various functions that are linked to this door query. This can be, for example, the switching on and off of lighting, energy saving, heating or a hot air blower motor or the like.
[016] Die erfindungsgemäße Schalteinrichtung bzw. die erfindungsgemäße Anordnung eignet sich insbesondere zum Einbau in ein Haushaltsgerät gemäß einem der Ansprüche 11 bis 13.The switching device according to the invention or the arrangement according to the invention is particularly suitable for installation in a household appliance according to one of claims 11 to 13.
[017] Weitere bevorzugte und vorteilhafte Varianten und Weiterbildungen der Erfindung lassen sich den abhängigen Ansprüchen sowie der nachfolgenden Figurenbeschreibung entnehmen. [018] Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels erläutert, wobei auf die beiliegenden Zeichnungen näher Bezug genommen wird. Dort zeigt:[017] Further preferred and advantageous variants and developments of the invention can be found in the dependent claims and the following description of the figures. The invention is explained below with reference to a preferred embodiment, reference being made to the accompanying drawings. There shows:
[019] Figur 1 eine schematische Frontansicht eines Gargeräts mit geöffneter Frontklappe und frontseitig zugänglichem Garraum,[019] FIG. 1 shows a schematic front view of a cooking appliance with an open front flap and a cooking chamber accessible from the front,

[021] Figuren 3 bis 5 schematische Darstellungen der Schalteimichtung gemäß Figur 2 in jeweils unterschiedlichen Betriebszuständen.Figures 3 to 5 are schematic representations of the switching device according to Figure 2 in different operating states.
[022] Das Gargerät 10 gemäß Figur 1 weist einen Garraum 12 auf, der mittels einer nach unten schwenkbaren Frontklappe 14 in horizontaler Richtung von außen zugänglich ist . Seitlich an einem Rahmen 16 einer Gehäusefront 18 des Gargeräts 10 befindet sich ein Türkontaktschalter 20, der bei geschlossener Frontklappe 14 von dieser verdeckt ist und damit von außen nicht erkennbar ist. Der Türkontaktschalter 20 wird von der Frontklappe 14 geschaltet und weist damit mindestens zwei Betriebszustände auf. Ein erster Betriebszustand kennzeichnet eine geschlossene Frontklappe 14, während ein zweiter Betriebszustand eine zumindest teilweise geöffnete Frontklappe 14 kennzeichnet. Der Türkontaktschalter 20 kann beispielsweise eine Garraumbe- leuchtung 22, ein elektrisches Heißluftgebläse 24 oder andere elektrische Verbraucher des Gargeräts 10 schalten.The cooking appliance 10 according to FIG. 1 has a cooking chamber 12 which is accessible from the outside in the horizontal direction by means of a front flap 14 which can be swiveled downwards. There is a door contact switch 20 on the side of a frame 16 of a housing front 18 of the cooking device 10, which is covered by the front flap 14 when the front flap 14 is closed and is therefore not visible from the outside. The door contact switch 20 is switched by the front flap 14 and thus has at least two operating states. A first operating state identifies a closed front flap 14, while a second operating state identifies an at least partially open front flap 14. The door contact switch 20 can, for example, switch a cooking space lighting 22, an electric hot air blower 24 or other electrical consumers of the cooking device 10.
[023] Gemäß vorliegender Erfindung ist der Türkontaktschalter 20 deaktivierbar, so dass die regulär durch Öffnen und Schließen der Frontklappe 14 vorgesehenen Schaltfunktionen nicht mehr ausgelöst werden.[023] According to the present invention, the door contact switch 20 can be deactivated, so that the switching functions provided by opening and closing the front flap 14 are no longer triggered.
[024] Die Wirkungsweise der deaktivierbaren Schaltfunktionen wird anhand eines bevorzugten Ausführungsbeispiels des Türkontaktschalters 20 mit Bezug auf die Figuren 2 bis 5 näher erläutert.[024] The mode of operation of the deactivatable switching functions is explained in more detail using a preferred exemplary embodiment of the door contact switch 20 with reference to FIGS. 2 to 5.
[025] Eine alternative Variante zur Deaktivierung des Türkontaktschalters 20 mittels eines in der Frontklappe 14 angeordneten Schiebers 50 wird weiter unten erläutert.[025] An alternative variant for deactivating the door contact switch 20 by means of a slide 50 arranged in the front flap 14 is explained further below.
[026] Der erfindungsgemäße Türkontaktschalter 20 umfasst ein Schaltelement 26, das in einer trennbaren Wirkverbindung mit einem elektrischen Schalter 38 steht. Im gezeigten Ausführungsbeispiel umfasst das Schaltelement 26 einen linear verschiebbaren Stößel 48, der mittels Federkraft in einer ersten Betriebsposition L gehalten ist. Diese erste Betriebsposition L ist jeweils in den Figuren 2 und 3 verdeutlicht. Die Feder ist im illustrierten Ausführungsbeispiel als Schraubenfeder 28 ausgebildet, die um den Außenumfang des Stößels 48 herum angeordnet ist und diesen gegen einem Gehäusevorsprung 30 abstützt. [027] Eine Stirnseite 32 des Stößels 48 kann von der sich schließenden Frontklappe 14 kontaktiert werden, wodurch der Stößel 48 bei sich vollständig schließender Frontklappe 14 gegen die Kraft der Schraubenfeder 28 nach links in eine zweite Betrieteposition L verschoben wird (vgl. Figur 4). Hierdurch wirkt ein am Außenumfang 2 des Stößels 48 angeordneter Schaltnocken 34 auf einen Schaltstift 36 des elektrischen Schalters 38. Der elektrische Schalter 38 kann beispielsweise ein herkömmlicher Mi- kroschalter sein, dessen elektrischer Kontakt durch lineares Verschieben des Schaltstiftes 36 geöffnet oder geschlossen wird. Die Linearverschiebung des Stößels 48 wird mit Hilfe der Schaltnocken 34 in eine hierzu senkrechte Linearverschiebung des Schaltstiftes 36 des elektrischen Schalters gewandelt. [028] Hierdurch ist die erwähnte Wirkverbindung zwischen dem verschiebbaren Stößel 48 und dem elektrischen Schalter 38 realisiert. In jeder der beiden Betriebspositionen L oder L bleibt der elektrische Schalter 38 deaktiviert, da sein Schaltstift 36 nicht 1 2 mehr von einer der Schaltnocken 34 erreicht wird.[026] The door contact switch 20 according to the invention comprises a switching element 26 which is in a separable operative connection with an electrical switch 38. In the exemplary embodiment shown, the switching element 26 comprises a linearly displaceable plunger 48, which is held in a first operating position L by means of spring force. This first operating position L is illustrated in FIGS. 2 and 3, respectively. In the illustrated exemplary embodiment, the spring is designed as a helical spring 28, which is arranged around and around the outer circumference of the plunger 48 is supported against a housing projection 30. An end face 32 of the plunger 48 can be contacted by the closing front flap 14, whereby the plunger 48 is displaced to the left against the force of the coil spring 28 into a second operating position L when the front flap 14 is fully closed (see FIG. 4). , As a result, a switching cam 34 arranged on the outer circumference 2 of the plunger 48 acts on a switching pin 36 of the electrical switch 38. The electrical switch 38 can be, for example, a conventional microswitch, the electrical contact of which is opened or closed by linearly moving the switching pin 36. The linear displacement of the plunger 48 is converted by means of the switching cams 34 into a linear displacement of the switching pin 36 of the electrical switch which is perpendicular thereto. [028] This realizes the above-mentioned operative connection between the displaceable plunger 48 and the electrical switch 38. In each of the two operating positions L or L, the electrical switch 38 remains deactivated, since its switching pin 36 is no longer reached by one of the switching cams 34.
[029] Figur 5 verdeutlicht die mögliche Trennung der Wirkverbindung zwischen Schaltelement 26 und elektrischem Schalter 38. Durch Verdrehen des Stößels 48 um seine Längsachse kann der Schaltnocken 34 aus dem Eingriffsbereich mit dem Schaltstift 36 gebracht werden, wodurch die Schaltfiinktion des erfindungsgemäßen Türkontaktschalters 20 deaktivierbar ist. Der Stößel 48 wird zwar weiterhin von der sich öffnenden oder schließenden Frontklappe 14 betätigt und linear verschoben, doch wird aufgrund des nicht mehr den Schaltstift 36 betätigenden Schaltnockens 34 die Schaltfiinktion des elektrischen Schalters 38 nicht mehr ausgelöst. Der Türkontaktschalter 20 ist auf diese Weise deaktiviert und löst keine elektrische Schaltfiinktion mehr aus. uf diese Weise kann gemäß der vorliegenden Erfindung die Wirkverbindung zwischen dem Schaltelement 26 und dem elektrischen Schalter 38 getrennt werden.Figure 5 illustrates the possible separation of the operative connection between switching element 26 and electrical switch 38. By rotating the plunger 48 about its longitudinal axis, the switching cam 34 can be brought out of the engagement area with the switching pin 36, whereby the switching function of the door contact switch 20 according to the invention can be deactivated , The plunger 48 is still actuated by the opening or closing front flap 14 and moved linearly, but due to the switching cam 34 no longer actuating the switching pin 36, the switching function of the electrical switch 38 is no longer triggered. The door contact switch 20 is deactivated in this way and no longer triggers an electrical switching function. In this way, according to the present invention, the operative connection between the switching element 26 and the electrical switch 38 can be separated.
[030] Um die aktivierte bzw. deaktivierte Wirkverbindung zwischen dem Schaltelement 26 und dem elektrischen Schalter 38 des Türkontaktschalters 20 zu stabilisieren, ist eine Rastfeder 40 vorgesehen, die im Gehäuse 42 des Türkontaktschalters 20 verankert ist und auf eine entsprechende Aussparung oder Erhebung am Außenumfang des Stößels 48 einwirkt. Die Rastfeder 40 kann beispielsweise eine Blattfeder oder dergleichen sein, deren freies Ende in zwei voneinander getrennte Aussparungen 44 am Außenumfang des Stößels 48 eingreifen kann. Die beiden Aussparungen 44 sind in diesem Fall vorzugsweise durch einen Steg 46 oder dergleichen voneinander getrennt, über den die Rastfeder 40 hinweggleiten muss, wenn der Stößel 48 um seine Längsachse verdreht wird. Auf diese Weise kann der Stößel 48 in mindestens zwei möglichen Winkelstellungen stabilisiert werden, die jeweils eine Aktivierung oder Deaktivierung des Türkontaktschalters 20 charakterisieren.In order to stabilize the activated or deactivated operative connection between the switching element 26 and the electrical switch 38 of the door contact switch 20, a detent spring 40 is provided, which is anchored in the housing 42 of the door contact switch 20 and on a corresponding recess or elevation on the outer circumference of the Plunger 48 acts. The detent spring 40 can be, for example, a leaf spring or the like, the free end of which can engage in two separate recesses 44 on the outer circumference of the plunger 48. In this case, the two cutouts 44 are preferably separated from one another by a web 46 or the like, over which the detent spring 40 must slide when the plunger 48 is rotated about its longitudinal axis. In this way, the plunger 48 can be stabilized in at least two possible angular positions, each of which characterize an activation or deactivation of the door contact switch 20.
[031] Eine bevorzugte Ausgestaltung des erfindungsgemäßen Türkontaktschalters 20 kann vorsehen, dass der Stößel 48 jeweils in eine vorgegebene Richtung um 90 Grad verdreht werden kann. Eine definierte Winkelstellung der Rastfeder 40 kann dafür sorgen, dass eine Verdrehung in die andere Richtung blockiert wird. Bei dieser Variante sind mindestens vier voneinander getrennte Aussparungen 44 am Außenumfang des Stößels 48 vorgesehen, die jeweils durch Stege 46 voneinander getrennt sind, so dass sich die Rastfeder 40 jeweils im Eingriff mit einer der vier Aussparungen 44 befinden kann, wodurch jeweils eine der beiden möglichen Zustände des Türkontaktschalters 20 definiert sein kann. Die Bedienung des Türkontaktschalters 20 wird auf diese Weise sehr vereinfacht, da der Benutzer keine Rücksicht darauf nehmen muss, ob sich der Stößel 48 in der richtigen Winkelstellung befindet. Der Stößel 48 braucht nur um 90 Grad weiter in die definierte Richtung verdreht werden, um damit den Wirkeingriff zwischen den Schaltnocken 34 und dem Schaltstift 36 zu aktivieren bzw. zu deaktivieren.A preferred embodiment of the door contact switch 20 according to the invention can provide that the plunger 48 can in each case be rotated through 90 degrees in a predetermined direction. A defined angular position of the detent spring 40 can ensure that rotation in the other direction is blocked. In this variant, at least four separate recesses 44 are provided on the outer circumference of the plunger 48, which are each separated from one another by webs 46, so that the detent spring 40 can be in engagement with one of the four recesses 44, which means that one of the two possible ones States of the door contact switch 20 can be defined. The operation of the door contact switch 20 is very simplified in this way, since the user does not have to take into account whether the plunger 48 is in the correct angular position. The plunger 48 only needs to be rotated 90 degrees further in the defined direction in order to activate or deactivate the active engagement between the switching cams 34 and the switching pin 36.
[032] Gegebenenfalls kann es von Vorteil sein, die möglichen Winkelstellungen des Stößels 48 mittels kleiner farbiger Markierungen zu kennzeichnen, damit der Benutzer jeweils ablesen kann, ob der Türkontaktschalter 20 aktiviert oder deaktiviert ist. Dies ermöglicht eine Beurteilung des Betriebszustandes des Türkontaktschalters 20, ohne dass zuvor das Gargerät 10 eingeschaltet werden muss.If appropriate, it can be advantageous to mark the possible angular positions of the plunger 48 by means of small colored markings so that the user can read in each case whether the door contact switch 20 is activated or deactivated. This enables an assessment of the operating state of the door contact switch 20 without the cooking device 10 having to be switched on beforehand.
[033] Eine alternative Möglichkeit zur Deaktivierung der Schaltfiinktionen des Türkontaktschalters 20 kann auch darin bestehen, dass der Stößel 48 beim vollständigen Schließen der Frontklappe 14 nicht mehr in seine zweite Betriebsposition L verschoben wird, sondern jederzeit in seiner ersten Betriebsposition L verharrt. Dies kann bspw. dadurch erreicht werden, dass ein Schieber 50 an der zum Türkon- taktschalter 20 weisenden Innenseite der Frontklappe 14 geöffnet wird, so dass der aus dem Rahmen 16 des Gargeräts 10 ragende Teil des Stößels 48 in eine zuvor vom Schieber 50 verschlossene Mulde 52 eintauchen kann. Diese Mulde 52 ist vorzugsweise so tief, dass der Stößel 48 auch bei vollständig geschlossener Frontklappe 14 nicht gedrückt wird, sondern durch die Kraft der Schraubenfeder 28 in seiner ersten Betriebsposition L gehalten wird.An alternative way of deactivating the switching functions of the door contact switch 20 can also be that the plunger 48 is no longer moved into its second operating position L when the front flap 14 is completely closed, but remains in its first operating position L at all times. This can be achieved, for example, by opening a slide 50 on the inside of the front flap 14 facing the door contact switch 20, so that the part of the plunger 48 protruding from the frame 16 of the cooking device 10 into a recess previously closed by the slide 50 52 can dip. This trough 52 is preferably so deep that the tappet 48 is not pressed even when the front flap 14 is completely closed, but is held in its first operating position L by the force of the helical spring 28.
