Description

Die vorliegende Erfindung betrifft ein Gargerät mit wenigstens einem beheizbaren Garraum, mit wenigstens einer den Garraum verschließenden Tür und mit wenigstens einem Auszug, auf dem wenigstens ein Träger zwischen wenigstens einer eingeschobenen und wenigstens einer ausgezogenen Position verfahrbar ist, wobei der Auszug wenigstens eine an dem Garraum befestigte untere Schiene und wenigstens eine zu der unteren Schiene beweglich angeordnete obere Schiene umfasst und wenigstens eine Selbsteinzugeinrichtung aufweist, wobei die gesamte Selbsteinzugeinrichtung in einem eigenen Gehäuse angeordnet ist, wobei die Selbstzugeinrichtung in der unteren Schiene aufgenommen ist und von der oberen Schiene überdeckt wird, wenn diese in der eingeschobenen Position ist, wobei die Selbsteinzugeinrichtung wenigstens eine erste Feder und wenigstens eine zweite Feder umfasst, deren Kraftwirkungen im Wesentlichen entgegengesetzt ausgerichtet sind, und wobei die erste Feder als Zugfeder und die zweite Feder als Dämpfungsfeder ausgestaltet sind.The present invention relates to a cooking appliance with at least one heatable cooking chamber, with at least one door closes the cooking chamber and at least one extract on which at least one carrier between at least one retracted and at least one extended position is movable, the extract at least one of the cooking space fixed lower rail and at least one upper rail movably arranged to the lower rail and having at least one Selbsteinzugeinrichtung, wherein the entire Selbsteinzugeinrichtung is arranged in a separate housing, wherein the self-zooming device is received in the lower rail and is covered by the upper rail, if this is in the retracted position, wherein the Selbsteinzugeinrichtung comprises at least a first spring and at least one second spring whose force effects are aligned substantially opposite, and wherein the first spring as a tension spring and the second Spring are designed as a damping spring.

Im Bereich der Haushaltsgeräte, insbesondere auch bei Gargeräten, wird bei der Entwicklung großer Wert auf einen größtmöglichen Komfort für einen Benutzer gelegt. Dabei soll ein Benutzer zum Beispiel bei der Zubereitung von Speisen möglichst gut durch das Gargerät unterstützt werden. Dazu können unter anderem Automatikprogramme vorgesehen sein, die eine einfache Bedienung des Gerätes ermöglichen. Aber auch die ergonomische Anordnung eines Gargerätes kann bei der Planung einer Küche berücksichtigt werden, um das Kochen bzw. das Beladen eines Gargerätes möglichst angenehm zu gestalten.In the field of household appliances, especially in cooking appliances, great importance is attached to the greatest possible comfort for a user in the development. In this case, a user should be supported as well as possible in the preparation of food by the cooking appliance, for example. For this purpose, among other things, automatic programs may be provided which allow easy operation of the device. But the ergonomic arrangement of a cooking appliance can be taken into account when planning a kitchen to make the cooking or loading a cooking appliance as pleasant as possible.

Um einem Benutzer zum Beispiel das Beladen des Garraumes eines Gargerätes weiter zu erleichtern, sind verschiedene Systeme bekannt geworden, um beispielsweise ein Backblech einfach und sicher in den Garraum zu befördern.In order to further facilitate a user, for example, the loading of the cooking chamber of a cooking appliance, various systems have become known, for example, to easily and safely transport a baking sheet into the cooking chamber.

Dazu kann zum Beispiel das Einschubsystem für die Backbleche an einer Tür angebracht sein, die schubladenähnlich ausgeführt ist. Ein Benutzer kann bei dieser Ausführung einfach die Tür wie eine Schublade durch Herausziehen öffnen, das Blech in die gewünschte Ebene einsetzen und die Schubladentür wieder schließen.For this purpose, for example, the insertion system for the baking trays may be attached to a door that is designed similar to a drawer. In this design, a user can simply open the door like a drawer by pulling it out, place the sheet metal in the desired level and close the drawer door again.

Auch Teleskopschienensysteme zum einfachen Beladen des Garraumes sind bekannt geworden. Dabei können die linke und die rechte Schiene einer Garebene zu einem gewissen Anteil aus dem Garraum herausgezogen werden, wodurch zum Beispiel ein Blech leicht auf diese Schienen aufgelegt werden kann. Die Teleskopschienen können dann einfach wieder mit dem Blech in den Garraum eingeschoben werden.Telescopic rail systems for easy loading of the cooking chamber have become known. In this case, the left and the right rail of a cooking plane can be pulled out to a certain extent from the cooking chamber, whereby, for example, a sheet can be easily placed on these rails. The telescopic rails can then be easily reinserted with the sheet in the oven.

Nachteilig bei den zuvor beschriebenen Systemen ist allerdings, dass das Einschieben des Bleches unter Umständen so schnell oder unkontrolliert erfolgt, dass Speisen zum Beispiel überschwappen können oder im schlimmsten Fall auch Beschädigungen am Gerät entstehen können. Auch kann das Backblech durch ein sehr ruppiges Einschieben an die Rückwand des Garraumes stoßen, wodurch unangenehme Geräusche entstehen können.A disadvantage of the systems described above, however, is that the insertion of the sheet may take place so quickly or uncontrollably that food can spill over, for example, or in the worst case, damage to the device may occur. Also, the baking sheet can be pushed by a very rough insertion of the rear wall of the cooking chamber, which can cause unpleasant noise.

Um dies zu vermeiden, kann die Verwendung eines Selbsteinzuges vorteilhaft sein. Bei manchen Ausführungen reicht es dann, die Schublade bzw. eine Teleskopschiene nur zu einem gewissen Maß von Hand in den Garraum einzuschieben. Der vollständige Einzug erfolgt, wie auch bei Schubladen oder Türen von zum Beispiel Küchenmöbeln schon bekannt, automatisch. Auch ein solcher Selbsteinzug erhöht den Bedienkomfort für einen Benutzer.To avoid this, the use of self-closing may be advantageous. In some embodiments, it is then sufficient to insert the drawer or a telescopic rail only to a certain extent by hand in the cooking chamber. The complete collection is done, as well as in drawers or doors of, for example, kitchen furniture already known automatically. Such a self-closing increases the ease of use for a user.

Allerdings ist es auch hier sinnvoll, das Einziehen abzudämpfen, um ein Überschwappen oder ein zu ruppiges Einziehen zu vermeiden. Dazu sind Dämpfungssystem mit Öldruckdämpfern bekannt geworden, die einen Selbsteinzug zuverlässig und effektiv abdämpfen können.However, it also makes sense here to dampen the retraction, in order to avoid over-sloshing or too rough pulling. For this damping system with oil pressure dampers have become known, which can reliably and effectively dampen a self-closing.

Für den Bereich der Gargeräte müssen diese Dämpfer allerdings auf die beim Garen von Speisen vorherrschenden Temperaturen ausgelegt werden. Da schon im normalen Garbetrieb sehr hohe Temperaturen vorliegen und zum Beispiel bei einem Pyrolysebetrieb Temperaturen um die 500°C erreicht werden können, eigenen sich die bekannten Öldruckdämpfer nicht für den Bereich der Gargeräte, insbesondere nicht für Gargeräte mit einer Pyrolysefunktion. Ein Selbsteinzug mit einem konventionellen Öldruckdämpfer ist oft schon bei Temperaturen über 100°C nicht mehr geeignet, da die notwendigen Dichtungen und die verwendeten Kunststoffe meist nicht temperaturfest sind.For the field of cooking appliances, however, these dampers must be designed for the temperatures prevailing when cooking food. Since very high temperatures are already present in normal cooking operation and, for example, temperatures of around 500 ° C. can be reached in a pyrolysis operation, the known oil pressure dampers are not suitable for cooking appliances, in particular not for cooking appliances with a pyrolysis function. A self-feeder with a conventional oil pressure damper is often no longer suitable even at temperatures above 100 ° C, since the necessary seals and the plastics used are usually not temperature-resistant.

Gargeräte der eingangs genannten Art bzw. Auszüge, die zum Einsatz in solchen Gargeräten geeignet sind, sind aus der DE 20 2008 008 541 U1 , der US 2006/082266 A1 , der DE 93 11 238 U1 und der US 2005/093406 A1 bekannt. Bei diesen Auszügen kommen Selbsteinzüge zum Einsatz, die eine erste Feder und wenigstens eine zweite Feder umfassen, deren Kraftwirkungen im Wesentlichen entgegengesetzt ausgerichtet sind. Allerdings sind diese Federeinzüge nicht dazu geeignet, die Einfahrbewegung der Schiene, die den Träger hält, zu dämpfen.Cooking appliances of the type mentioned or extracts that are suitable for use in such cooking appliances, are from the DE 20 2008 008 541 U1 , of the US 2006/082266 A1 , of the DE 93 11 238 U1 and the US 2005/093406 A1 known. In these extracts self-indentations are used which comprise a first spring and at least one second spring whose force effects are aligned substantially opposite. However, these spring detents are not suitable to dampen the retraction movement of the rail that holds the carrier.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Gargerät zur Verfügung zu stellen, das ein Auszugsystem zum einfachen Beladen des Garraumes zur Verfügung stellt, bei dem eine Dämpfung des Selbsteinzugs auch bei hohen Temperaturen effektiv und dauerhaft gewährleistet wird.It is therefore the object of the present invention to provide a cooking appliance which provides an extension system for easy loading of the cooking space, in which a damping of the self-closing is ensured effectively and permanently, even at high temperatures.

Diese Aufgabe wird gelöst durch ein Gargerät mit den Merkmalen des Anspruchs 1. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen und dem Ausführungsbeispiel.This object is achieved by a cooking appliance with the features of claim 1. Further embodiments will be apparent from the dependent claims and the embodiment.

Das erfindungsgemäße Gargerät umfasst wenigstens einem beheizbaren Garraum und wenigstens eine den Garraum verschließende Tür. Weiter ist wenigstens ein Auszug vorgesehen, auf dem wenigstens ein Träger, wie zum Beispiel ein Rost, ein Blech oder eine Wanne, zwischen wenigstens einer eingeschobenen und wenigstens einer ausgezogenen Position verfahrbar ist. Dabei weist der Auszug wenigstens eine an dem Garraum befestigte erste Schiene und wenigstens eine zu der ersten Schiene beweglich angeordnete zweite Schiene auf. Ferner ist wenigstens eine Selbsteinzugeinrichtung vorgesehen, welche wenigstens eine erste und wenigstens eine zweite Feder umfasst, deren Kraftwirkungen im Wesentlichen entgegengesetzt ausgerichtet sind, wobei die erste Feder als Zugfeder ausgebildet ist. Des Weiteren ist die zweite Feder als Dämpfungsfeder einer Dämpfungseinrichtung ausgestaltet, welche ein zu schnelles Einziehen der zweiten Schiene vermeidet.The cooking appliance according to the invention comprises at least one heatable cooking chamber and at least one door closing the cooking chamber. Furthermore, at least one drawer is provided on which at least one support, such as a grate, a sheet or a tub, can be moved between at least one inserted and at least one extended position. In this case, the drawer has at least one first rail fastened to the cooking chamber and at least one second rail movably arranged relative to the first rail. Further, at least one Selbsteinzugeinrichtung is provided, which comprises at least a first and at least one second spring whose force effects are aligned substantially opposite, wherein the first spring is formed as a tension spring. Furthermore, the second spring is designed as a damping spring of a damping device, which avoids too fast retraction of the second rail.

Das erfindungsgemäße Gargerät kann insbesondere als Backofen, Herd, Mikrowelle, Dampfgarer oder Kombigerät ausgeführt sein. Allgemein ist aber auch jedes andere Gargerät mit einem beheizbaren Garraum umfasst.The cooking appliance according to the invention can be designed in particular as an oven, stove, microwave, steamer or combi appliance. In general, however, any other cooking appliance with a heated cooking chamber includes.

Der Auszug kann insbesondere auch als Teleskopauszug ausgestaltet sein. Dabei kann auch die Verwendung von mehr als zwei Schienen vorteilhaft sein. Insbesondere um eine lange Ausfahrstrecke zu erzielen, können mehrere Teleskopschienen vorgesehen sein. Auch die Ausgestaltung des Auszugs als Schubladentür kann in bestimmten Ausführungen sinnvoll und zweckmäßig sein.The extract can in particular be designed as a telescopic extension. It may also be advantageous to use more than two rails. In particular, to achieve a long extension distance, a plurality of telescopic rails may be provided. The design of the drawer as a drawer door can be useful and appropriate in certain embodiments.

Die Schienen können auf verschiedene Arten in Verbindung stehen. Eine besonders geeignete Methode ist die Verwendung einer Führungsschiene, die eine Beweglichkeit der beiden Schienen zueinander über Kugeln bewirkt.The rails can communicate in different ways. A particularly suitable method is the use of a guide rail, which causes a mobility of the two rails to each other via balls.

Ein derart ausgestaltetes Gargerät bietet viele Vorteile. Ein erheblicher Vorteil ist, dass durch die spezielle Gestaltung der Selbsteinzugeinrichtung mit zwei entgegengesetzt wirkenden Federn ein Selbsteinzug mit einer zuverlässigen Dämpfung zur Verfügung gestellt wird. Insbesondere eignet sich diese Art der Dämpfung mit den zwei Federn besonders gut für den Einsatz in Gargeräten, da die Dämpfung selbst bei sehr hohen Temperaturen zuverlässig und dauerhaft gewährleistet wird. Gerade bei der Pyrolyse wird im Garraum ein sehr hohes Temperaturniveau erreicht, das bis 500°C betragen kann. Die zuvor beschriebene Selbsteinzugeinrichtung arbeitet auch bei solchen Temperaturen problemlos.Such ausgestaltetes cooking appliance offers many advantages. A significant advantage is that the self-closing device with two oppositely acting springs provides self-closing with reliable damping thanks to the special design of the self-closing device. In particular, this type of damping with the two springs is particularly well suited for use in cooking appliances, since the damping is ensured reliably and permanently, even at very high temperatures. Especially in the pyrolysis is achieved in the cooking a very high temperature level, which may be up to 500 ° C. The self-retraction device described above works well even at such temperatures.

Bei bekannten Dämpfungssystemen mit zum Beispiel einem Öldruckzylinder ist oft insbesondere eine solche Hitzebeständigkeit nicht gegeben, wodurch eine zuverlässige Dämpfung in einem heißen Garraum - wenn überhaupt - nicht dauerhaft gewährleistet werden kann. Dies resultiert beispielsweise aus Dichtungen an dem Druckzylinder, die porös werden können, wodurch der nötige Druck verloren geht.In known damping systems with, for example, an oil pressure cylinder, in particular such a heat resistance is often not given, whereby a reliable damping in a hot cooking space - if any - can not be guaranteed permanently. This results for example from seals on the printing cylinder, which can become porous, whereby the necessary pressure is lost.

Beim Ausziehen des Auszugs aus dem Garraum wird die erste Feder gespannt. Beim Zurückschieben des Auszugs in den Backofen zieht diese Feder die zweite Schiene wieder vollständig in den Garraum zurück. Daher ist die erste Feder bevorzugt als Zugfeder ausgestaltet. Da die zweite Feder die Kraftwirkung der ersten Feder abdämpfen soll, um ein zu schnelles oder ruppiges Einziehen zu vermeiden, ist die zweite Feder als Dämpfungsfeder ausgestaltet. Dabei ist es zweckmäßig, dass die Zugfeder so stark ausgewählt wird, dass sie die Kraft der Dämpfungsfeder überwinden kann. Je nach Kraftdifferenz zwischen den beiden Federn erfolgt eine Abstufung in der Dämpfung.When pulling out the extract from the cooking chamber, the first spring is tensioned. When pushing back the extract in the oven this spring pulls the second rail back completely into the cooking chamber. Therefore, the first spring is preferably designed as a tension spring. Since the second spring is to dampen the force of the first spring to avoid too fast or rough pulling, the second spring is designed as a damping spring. It is expedient that the tension spring is selected so strong that it can overcome the force of the damping spring. Depending on the force difference between the two springs, there is a gradation in the damping.

Die Dämpfungsfeder ist in bevorzugten Ausgestaltungen als Drahtseildruckfeder ausgebildet. Durch die Ausgestaltung als Mehrdrahtfeder kann eine effektive Dämpfwirkung erreicht werden, wobei die Dämpfwirkung von der Länge und der Stärke der Drahtseildruckfeder abhängt.The damping spring is formed in preferred embodiments as a wire rope compression spring. The design as a multi-wire spring, an effective damping effect can be achieved, the damping effect of the length and the strength of the wire rope spring depends.

Die Selbsteinzugeinrichtung ist bevorzugt an der ersten Schiene befestigt ist. Dabei ist es besonders zweckmäßig, die Selbsteinzugeinrichtung in der ersten Schiene anzuordnen. Dadurch kann die Einzugeinrichtung platzsparend verbaut werden und ist vor Verunreinigungen von zum Beispiel Wrasen oder anderen Verschmutzungen untergebracht. Die zweite Schiene würde in solchen Ausgestaltungen die Selbsteinzugeinrichtung von oben abdecken.The Selbsteinzugeinrichtung is preferably attached to the first rail. It is particularly expedient to arrange the Selbsteinzugeinrichtung in the first rail. As a result, the retraction device can be installed in a space-saving manner and is accommodated against contamination of, for example, fumes or other contaminants. The second rail would cover the Selbsteinggeinrichtung from above in such embodiments.

Zum Spannen der ersten Feder umfasst die Selbsteinzugeinrichtung in bevorzugten Ausgestaltungen eine Führungseinrichtung. Diese kann besonders entlang der Einzug- bzw. Auszugrichtung der zweiten Schiene verfahren werden.For tensioning the first spring, the self-retraction device in preferred embodiments comprises a guide device. This can be moved in particular along the pull-in or extension direction of the second rail.

Es ist weiter bevorzugt, dass die erste Feder mit einem ersten Ende an einem ortsfesten Teil der Selbsteinzugeinrichtung und mit einem zweiten Ende an der Führungseinrichtung verbunden ist. Dadurch kann die Führungseinrichtung, wenn diese verfahren wird, die erste Feder spannen.It is further preferred that the first spring is connected at a first end to a stationary part of the self-closing device and at a second end to the guide device. As a result, the guide device, when this is moved, tension the first spring.

Das Verfahren der Führungseinrichtung und somit das Spannen der ersten Feder erfolgt automatisch beim Ausziehen der zweiten Schiene aus dem Garraum. Dazu ist bevorzugt der zweiten Schiene ein Mitnehmer zugeordnet, der dazu geeignet und ausgebildet ist, in die Führungseinrichtung einzugreifen.The method of the guide device and thus the tensioning of the first spring takes place automatically when the second rail is pulled out of the cooking chamber. For this purpose, a driver is preferably associated with the second rail, which is suitable and adapted to engage in the guide device.

Wenn die erste Feder ausreichend gespannt ist, bzw. wenn die Führungseinrichtung eine vorbestimmte Position erreicht hat, wird der Mitnehmer aus der Eingriffstelle an der Führungseinrichtung freigegeben und die Führungseinrichtung greift in eine Rasteinrichtung der Selbsteinzugeinrichtung ein. Dadurch wir die erste Feder in dem gespannten Zustand gehalten.When the first spring is sufficiently tensioned, or when the guide device has reached a predetermined position, the driver is released from the engagement point on the guide device and the guide device engages in a latching device of the self-retraction device. This kept the first spring in the tensioned state.

Wird die bewegliche Schiene wieder in den Garraum eingeschoben, greift der Mitnehmer nach einer vorbestimmten Strecke wieder in die Eingriffstelle an der Führungseinrichtung ein, wodurch die Führungseinrichtung wieder aus der Rasteinrichtung freigegeben wird. Die gespannte erste Feder zieht sich zusammen und zieht dadurch die bewegliche Schiene in den Garraum zurück.If the movable rail is pushed back into the cooking chamber, the driver engages again after a predetermined distance in the point of engagement with the guide means, whereby the guide means is released again from the locking device. The tensioned first spring contracts and thereby pulls the movable rail back into the cooking chamber.

Um die Zugwirkung der gespannten ersten Feder abzudämpfen, ist in weiteren bevorzugten Ausgestaltungen an der Führungseinrichtung eine Kontakteinrichtung vorgesehen. Diese steht zumindest in der eingeschobenen Position der zweiten Schiene mit der zweiten Feder in Wirkverbindung. Dadurch wird die Einzugbewegung der ersten Feder durch die entgegengesetzte Wirkung der zweiten Feder effektiv abgedämpft.In order to dampen the tensile effect of the tensioned first spring, a contact device is provided in further preferred embodiments on the guide device. This is at least in the retracted position of the second rail with the second spring in operative connection. As a result, the retraction movement of the first spring is effectively damped by the opposite action of the second spring.

In Figur 1 ist in einer perspektivischen Ansicht ein erfindungsgemäßes Gargerät 1 stark schematisch dargestellt, welches hier als Herd 50 bzw. als Standgerät ausgeführt ist. Das Gargerät 1 weist ein Gehäuse 5 auf, an dem ein Garraum 2 vorgesehen ist, der mit einer Tür 3 verschließbar ist. Bei geöffneter Tür 3 kann ein Gargut in den Garraum 2 eingebracht werden. In dem Garraum 2 können die Speisen dann mittels einer Heizquelle 6 gegart werden. Dazu eignet sich insbesondere die Verwendung von zum Beispiel Ober- und/oder Unterhitze, einer Umluft- oder einer Grillfunktion. Eine Heizquelle 6 ist in Figur 1 jedoch nicht dargestellt.In FIG. 1 a cooking appliance 1 according to the invention is shown very schematically in a perspective view, which is designed here as a hearth 50 or as a standalone unit. The cooking appliance 1 has a housing 5, on which a cooking chamber 2 is provided, which can be closed by a door 3. When the door 3 is open, a food can be introduced into the cooking chamber 2. In the cooking chamber 2, the food can then be cooked by means of a heating source 6. For this purpose, in particular the use of, for example, top and / or bottom heat, a convection or a grill function is suitable. A heating source 6 is in FIG. 1 but not shown.

Auf dem Herd 50 ist ein Kochfeld 7 angeordnet, das in mehrere Kochzonen 8 aufgeteilt ist. Man kann die gewünschten Einstellungen für einen Garvorgang über einige Bedienelemente 9 an einer Bedienblende 10 vornehmen. Die Bedienblende 10 kann auch eine Anzeigeeinrichtung 11 wie zum Beispiel ein Display 12 beinhalten, auf dem der aktuelle Zustand des Gargerätes 1 und die eingestellten Werte angezeigt werden können.On the stove 50, a hob 7 is arranged, which is divided into several cooking zones 8. You can make the desired settings for cooking over some controls 9 on a control panel 10. The control panel 10 may also include a display device 11 such as a display 12, on which the current state of the cooking appliance 1 and the set values can be displayed.

Durch das Sichtfenster 13 in der Tür 3 sieht man eine Aufnahmeeinrichtung 14 zum Aufnehmen von einem Träger 4. Die Aufnahmeeinrichtung 14 ist an der linken Seitenwand 16 des Garraumes 2 angeordnet und in dem hier gezeigten Ausführungsbeispiel als Teleskopauszug 120 ausgebildet. Auch andere Aufnahmeeinrichtungen 14, insbesondere verfahrbare Aufnahmeeinrichtungen 14, können sinnvoll eingesetzt werden.Through the viewing window 13 in the door 3 can be seen a receiving device 14 for receiving from a support 4. The receiving device 14 is disposed on the left side wall 16 of the cooking chamber 2 and formed in the embodiment shown here as a telescopic extension 120. Other receiving devices 14, in particular movable receiving devices 14, can be used meaningfully.

Von den vier vorhandenen Garebenen 15 sind durch das Sichtfenster 13 nur drei Ebenen 15 sichtbar. Wenn die Tür 3 geöffnet ist, kann man den Auszug 100 in der gewünschten Garebene 15 ausziehen, um einen Träger - zum Beispiel ein Blech, ein Rost oder eine Garwanne - leicht und komfortabel auf die Aufnahmeeinrichtung 14 aufzulegen. Der Träger 4 kann anschließend einfach auf dem Teleskopauszug 120 wieder in den Garraum 2 eingeschoben werden. Dadurch ist ein komfortables und auch ein sehr sicheres Einbringen eines Trägers 4 in den Garraum 2 gewährleistet.Of the four existing garden levels 15 only three levels 15 are visible through the viewing window 13. When the door 3 is opened, the drawer 100 can be pulled out in the desired cooking plane 15 in order to place a carrier - for example a sheet metal, a grate or a pan - easily and comfortably on the receiving device 14. The carrier 4 can then simply be pushed back into the cooking chamber 2 on the telescopic extension 120. This ensures a comfortable and also a very safe introduction of a carrier 4 in the cooking chamber 2.

In Figur 2 ist in einer perspektivischen Ansicht ein Gargerät 1 abgebildet, das hier als Einbaubackofen 60 ausgeführt ist und stark schematisch dargestellt ist. An dem Gehäuse 5 ist wieder ein Garraum 2 angeordnet, der von einer Tür 3 verschließbar ist. An der linken Seitenwand 16 des Garraumes 2 erkennt man die Aufnahmeeinrichtung 14, die hier durch einen Teleskopauszug 120 auf vier Garebenen 15 zur Verfügung gestellt wird.In FIG. 2 is a cooking appliance 1 shown in a perspective view, which is designed here as a built-in oven 60 and is shown very schematically. On the housing 5, a cooking chamber 2 is again arranged, which can be closed by a door 3. On the left side wall 16 of the cooking chamber 2 can be seen the receiving device 14, which is provided here by a telescopic extension 120 on four cooking levels 15 available.

Die schematische Ansicht eines erfindungsgemäßen Auszugs 100 in eingeschobener Position 101 ist in Figur 3 gezeigt. Ein solcher Auszug 100 kann wie in dem hier gezeigten Ausführungsbeispiel eine erste Schiene 103 umfassen, die ortsfest an dem Garraum 2 aufgenommen ist. Zu der ersten Schiene 103 beweglich angeordnet ist eine zweite Schiene 104 vorgesehen, die zum Bespiel über Kugeln, die hier nicht näher dargestellt sind, auf der ersten Schiene 103 verfahrbar ist. Auch Anordnungen mit mehr Schienen und andere Arten des Zusammenspiels zwischen den Schienen können je nach Anwendungsfall vorteilhaft eingesetzt werden.The schematic view of an extract 100 according to the invention in the inserted position 101 is shown in FIG FIG. 3 shown. Such an extract 100 may, as in the embodiment shown here, comprise a first rail 103, which is received in a stationary manner on the cooking chamber 2. Movably arranged to the first rail 103 is a second rail 104th provided, for example via balls, which are not shown here, on the first rail 103 is movable. Also arrangements with more rails and other types of interaction between the rails can be used advantageously depending on the application.

Zum Einbringen eines Trägers in den Garraum 2 eines Gargerätes 1 kann ein solcher Auszug 100 bzw. wenigstens die Schiene 104 aus dem Garraum 2 herausgezogen werden. Der Träger 4 wird dann auf die ausgezogenen Schienen 104 aufgelegt und kann dann einfach in den Garraum 2 eingeschoben werden.For introducing a carrier into the cooking chamber 2 of a cooking appliance 1, such an extract 100 or at least the rail 104 can be pulled out of the cooking chamber 2. The carrier 4 is then placed on the solid rails 104 and can then be easily inserted into the cooking chamber 2.

Damit ein Benutzer den Träger 4 auf dem Teleskopauszug 120 nicht zu schnell und/oder zu unsanft in den Garraum 2 einschieben kann, ist die Verwendung einer Selbsteinzugeinrichtung 105 vorteilhaft. Ein Benutzer muss dann den Träger 4 nur ein gewisses Stück in den Garraum 2 einschieben, bis der Selbsteinzug 105 aktiviert wird und den Träger komplett in den Garraum 2 einzieht. Bei dieser Art des Einzugs ist dann die Verwendung eines Dämpfers vorgesehen, um das letzte Stück abzufedern. So kann zum Beispiel ein Anschlagen des Trägers 4 an der Rückwand des Garraumes 2 vermieden werden.So that a user can not push the carrier 4 on the telescopic extension 120 too quickly and / or too roughly into the cooking space 2, the use of a self-closing device 105 is advantageous. A user then has to insert the carrier 4 only a certain distance into the cooking chamber 2 until the self-closing 105 is activated and the carrier moves completely into the cooking chamber 2. In this type of collection then the use of a damper is provided to cushion the last piece. Thus, for example, a striking of the carrier 4 on the rear wall of the cooking chamber 2 can be avoided.

Ein Teil des Selbsteinzugs 105 ist in Figur 4 zu sehen. In der Figur ist der Teleskopauszug 120 in der ausgezogenen Position 102 dargestellt. Am rechten Ende der ersten Schiene 103 erkennt man einen Teil der Selbsteinzugeinrichtung 105. Diese ist in dem hier gezeigten Ausführungsbeispiel an der unteren Schiene 103 befestigt. Genauer gesagt ist die Selbsteinzugeinrichtung 105 in der unteren Schiene 103 angeordnet. Man erkennt allerdings nur einen Teil des Gehäuses 121 der Selbsteinzugeinrichtung 105 und einen Teil der ersten Feder 106. Auch andere Anordnungen der Selbsteinzugeinrichtung 105 können je nach Ausführungsform vorteilhaft sein. Bei der Verwendung von mehr als zwei Schienen 103, 104 kann auch die Verwendung mehrerer Selbsteinzugseinrichtungen 105 vorgesehen sein.Part of the self-induction 105 is in FIG. 4 to see. In the figure, the telescopic extension 120 is shown in the extended position 102. At the right end of the first rail 103, a part of the self-closing device 105 can be seen. This is fastened to the lower rail 103 in the exemplary embodiment shown here. More specifically, the self-feeding device 105 is disposed in the lower rail 103. However, only a part of the housing 121 of the self-closing device 105 and a part of the first spring 106 can be seen. Other arrangements of the self-closing device 105 may also be advantageous, depending on the embodiment. When using more than two rails 103, 104, the use of multiple self-closing devices 105 may also be provided.

Eine detailliertere Darstellung der Selbsteinzugeinrichtung 105 ist in den Figuren 5 und 6 dargestellt. Dabei ist die gesamte Einrichtung 105 in vorteilhaften Ausgestaltungen in einem eigenen Gehäuse 121 angeordnet. So kann die Selbsteinzugeinrichtung 105 einfach montiert werden und sogar unter Umständen leicht nachgerüstet werden. Die Selbsteinzugeinrichtung 105 ist in dem hier gezeigten Beispiel in der unteren Schiene 103 aufgenommen und wird auch von der oberen Schiene 104 überbedeckt, wenn diese in der eingefahrenen Position 101 ist.A more detailed illustration of the Selbsteinggeinrichtung 105 is in the Figures 5 and 6 shown. In this case, the entire device 105 is arranged in advantageous embodiments in a separate housing 121. Thus, the Selbsteingegeinrichtung 105 can be easily mounted and even easily retrofitted under certain circumstances. The Selbsteinggeinrichtung 105 is included in the example shown here in the lower rail 103 and is also covered by the upper rail 104 when it is in the retracted position 101.

Der Wirkmechanismus der Selbsteinzugeinrichtung 105 besteht aus einer ersten Feder 106, die als Zugfeder 108 ausgebildet ist. An einem ortsfesten Teil 115 der Selbsteinzugeinrichtung 105 ist ein erstes Ende 114 dieser Feder 106 befestigt. Die Feder 106 erstreckt sich bis zu der Führungseinrichtung 111 und ist an einem zweiten Ende 116 mit dieser verbunden.The mechanism of action of the self-closing device 105 consists of a first spring 106, which is designed as a tension spring 108. On a stationary part 115 of the self-closing device 105, a first end 114 of this spring 106 is attached. The spring 106 extends to the guide means 111 and is connected at a second end 116 thereto.

Die erste Feder 106 ist in Figur 5 in einem entspannten Zustand dargestellt. In eine Aussparung 122 an der Führungseinrichtung 111 greift ein der zweiten Schiene 104 zugeordneter Mitnehmer ein. Wird die Schiene 104 ausgezogen, zieht der Mitnehmer 117 die Führungseinrichtung 111 mit, wodurch die erste Feder 106 der Selbsteinzugeinrichtung 105 gespannt wird. An einer vorbestimmten Position greift die Führungseinrichtung 111 in eine Rasteinrichtung 118 an der Selbsteinzugeinrichtung 105 ein und der Mitnehmer 117 verlässt die Aussparung 122. Die Schiene 104 kann dann ganz ausgezogen werden.The first spring 106 is in FIG. 5 shown in a relaxed state. In a recess 122 on the guide device 111 engages the second rail 104 associated driver. If the rail 104 is pulled out, the driver 117 pulls the guide device 111, whereby the first spring 106 of the self-closing device 105 is tensioned. At a predetermined position, the guide device 111 engages in a latching device 118 on the self-closing device 105 and the driver 117 leaves the recess 122. The rail 104 can then be pulled out completely.

In Figur 6 ist der gespannte Zustand der Selbsteinzugeinrichtung 105 dargestellt. Zum Einfahren der Schiene 104 wird diese in Richtung des Garraumes 2 geschoben. Sobald der Mitnehmer 117 wieder in die Aussparung 122 der Führungseinrichtung eingreift, löst diese sich aus der Rasteinrichtung 118, wodurch die vorbelastete Feder 106, die als Zugfeder 108 ausgestaltet ist, sich zusammenzieht. Durch das Eingreifen des Mitnehmers 117 in die Selbsteinzugeinrichtung 105 wird die Schiene 104 durch die Zugfeder 108 in den Garraum 2 automatisch eingezogen.In FIG. 6 the tensioned state of Selbsteinggeinrichtung 105 is shown. To retract the rail 104, this is pushed in the direction of the cooking chamber 2. As soon as the driver 117 engages again in the recess 122 of the guide device, it releases from the latching device 118, whereby the preloaded spring 106, which is designed as a tension spring 108, contracts. By the engagement of the driver 117 in the Selbsteinzugeinrichtung 105, the rail 104 is automatically retracted by the tension spring 108 in the cooking chamber 2.

Um ein zu schnelles und/oder ruppiges Einschieben bzw. Einziehen der Schiene 104 zu vermeiden, ist eine Dämpfungseinrichtung 123 vorgesehen, die hier als Dämpfungsfeder 109 ausgestaltet ist und die zweite Feder 107 der Selbsteinzugeinrichtung 105 darstellt. Dabei ist die Dämpfungsfeder 109 bevorzugt als Drahtseildruckfeder 110 bzw. Mehrdrahtfeder ausgestaltet.In order to avoid a too rapid and / or rough insertion or retraction of the rail 104, a damping device 123 is provided, which is designed here as a damping spring 109 and the second spring 107 of the Selbsteinzugeinrichtung 105 represents. In this case, the damping spring 109 is preferably configured as a wire rope compression spring 110 or a multi-wire spring.

Beim Zurückfahren der Führungseinrichtung 111 kommt eine der Führungseinrichtung 111 zugeordnete Kontakteinrichtung 119 in Kontakt mit der zweiten Feder 107, wodurch das Einziehen der Schiene 104 durch die Kraft der ersten Feder 106 mittels der Dämpfungsfeder 109 abgefedert wird. Dadurch wird ein gedämpfter Selbsteinzug 105 zur Verfügung gestellt.When the guide device 111 retracts, a contact device 119 assigned to the guide device 111 comes into contact with the second spring 107, as a result of which the retraction of the rail 104 is cushioned by the force of the first spring 106 by means of the damping spring 109. As a result, a damped self-closing 105 is provided.

Es ist vorteilhaft, dass die Zugfeder 108 wenigstens eine geringfügig größere Zugkraft aufweist, als die von der zweiten Feder 107 bewirkte Dämpfwirkung. Sonst könnte ein komplettes Einziehen der Schiene 104 verhindert werden.It is advantageous that the tension spring 108 has at least a slightly greater tensile force than the damping effect caused by the second spring 107. Otherwise, a complete retraction of the rail 104 could be prevented.

Die Figuren 7 und 8 zeigen den schon zu den Figuren 5 und 6 beschriebenen Mechanismus des gedämpften Selbsteizugs einer Teleskopschiene in einem leicht modifizierten Ausführungsbeispiel.The FIGS. 7 and 8 show that already to the Figures 5 and 6 described mechanism of the attenuated Selbstbsteizugs a telescopic rail in a slightly modified embodiment.

Es liegt weiter im Rahmen des Könnens eines Fachmanns, die beschriebenen Ausführungsbeispiele in nicht dargestellter Weise abzuwandeln, um die beschriebenen Effekte zu erzielen, ohne dabei den Rahmen der Erfindung zu verlassen.
