Description

Die Erfindung betrifft ein Haushaltsgerät nach dem Oberbegriff des Anspruchs 1 wie es z.B. das Dokument DE 202004 00 5475 U1 zeigt.The invention relates to a household appliance according to the preamble of claim 1 such as the document DE 202004 00 5475 U1 shows.

Eine Teleskopauszugsvorrichtung ist bereits aus der DE 199 49 239 A1 bekannt. Die bekannte Teleskopauszugsvorrichtung ist zur Befestigung an einem in dem Behandlungsraum eines Haushaltsgeräts angeordneten Traggestell ausgebildet, das mindestens zwei voneinander beabstandete vertikale Pfosten und mindestens ein die beiden Pfosten verbindendes, horizontal verlaufendes Paar vertikal voneinander beabstandeter Führungsstangen zur Führung einer in den Behandlungsraum einschiebbaren Ablage aufweist. Die Teteskopauszugsvorrichtung umfasst eine Halteschiene und eine Laufschiene zur Auflage einer aus den Behandlungsraum ausfahrbaren Ablage, wobei die bekannte Teleskopauszugsvorrichtung fest und unlösbar mit dem Traggestell verbunden ist.A telescopic extension device is already out of the DE 199 49 239 A1 known. The known telescopic extension device is designed for attachment to a arranged in the treatment room of a household appliance support frame having at least two spaced vertical posts and at least one connecting the two posts, horizontally extending pair of vertically spaced guide rods for guiding a retractable into the treatment room tray. The Teteskopauszugsvorrichtung comprises a holding rail and a running rail for supporting a retractable from the treatment room tray, wherein the known telescopic extension device is firmly and permanently connected to the support frame.

Aus der US 2005/0217501 A1 ist ferner ein Paar von Teleskopauszugsvorrichtungen zur Befestigung an in dem Behandlungsraum eines Haushaltsgeräts angeordneten Traggestellen bekannt. Die Teleskopauszugsvorrichtungen weisen jeweils eine Halteschiene und eine Laufschiene auf und sind mit einer Ablage für Gargut fest verbunden, so dass die Ablage mit den beiden daran fest angeordneten Teleskopauszugsvorrichtungen eine bauliche Einheit bildet, die zum einen aus den Behandlungsraum ausfahrbar ist. Zum anderen ist die so gebildete Einheit als Ganzes von den Traggestellen lösbar und vollständig aus dem Behandlungsraum entfernbar. Die Traggestelle weisen mindestens zwei voneinander beabstandete vertikale Pfosten und mehrere die beiden Pfosten verbindende, horizontal verlaufende und vertikal voneinander beabstandete Führungsstangen auf, an denen die Ablage über an den Halteschienen der Teleskopauszugsvorrichtungen angeformten oder angeordneten Befestigungsvorrichtungen lösbar befestigbar sind. Die Befestigungsvorrichtungen sind hier derart ausgebildet, dass die aus Ablage und daran fixierten Teleskopauszugsvorrichtungen gebildete Einheit auch in vollständig aus dem Behandlungsraum ausgezogenen Zustand und mit auf der Ablage abgelegtem Gargut nicht kippt.From the US 2005/0217501 A1 Furthermore, a pair of telescopic extension devices for attachment to arranged in the treatment room of a household appliance supporting frames is known. The telescopic extension devices each have a retaining rail and a running rail and are firmly connected to a shelf for food, so that the tray forms a structural unit with the two fixed thereto telescopic pull-out devices, which is on the one hand from the treatment room extendable. On the other hand, the unit thus formed as a whole is detachable from the supporting frames and completely removable from the treatment room. The support frames have at least two spaced apart vertical posts and a plurality of the two posts connecting, horizontally extending and vertically spaced guide rods on which the tray are releasably secured via integrally formed on the support rails of the telescopic extension devices or arranged fastening devices. The fastening devices are designed in this case such that the unit formed from the tray and the telescopic pull-out devices fixed thereto does not tip over even in the fully extended state from the treatment room and with the food to be stored on the shelf.

Die DE 101 16 471 A1 offenbart im Unterschied zu den vorgenannten Ausführungsformen einen völlig anderen Lösungsansatz für eine Teleskopauszugsvorrichtung. Die darin beschriebene Teleskopauszugsvorrichtung ist weder an dem Traggestell noch an der Ablage fixiert, sondern als Einzelteil verwendbar. Die Teleskopauszugsvorrichtung ist hier auf ein horizontal verlaufendes Paar vertikal voneinander beabstandeter Führungsstangen zur Führung einer in den Behandlungsraum einschiebbaren Ablage ausgebildet. Hierdurch ist es im Unterschied zu den vorgenannten Ausführungsformen ermöglicht, die Teleskopauszugsvorrichtung unabhängig von der Ablage in jeder beliebigen Höhenlage an einem Paar von Führungsstangen zu befestigen. Auf diese Weise ist es möglich, das Traggestell sehr flexibel zu nutzen; und zwar handelsübliche Ablagen direkt in das Traggestell einzuschieben und an die Verwendung der Teleskopauszugsvorrichtung angepasste Ablagen, also Ablagen mit einer geringeren Breite, mittels der Teleskopauszugsvorrichtung an dem Traggestell zu haltern. Hierzu sind die Ablagen lose auf die Laufschienen der Teleskopauszugsvorrichtungen auflegbar. Damit die Ablagen in dem aus dem Behandlungsraum ausgezogenen Zustand bei dieser Ausführungsform nicht kippen, werden hier nicht einzelne Führungsstangen, sondern paarweise angeordnete Führungsstangen verwendet, die eine Stabilisierung der lose aufgelegten Ablagen in vertikaler Richtung bewirken.The DE 101 16 471 A1 discloses, in contrast to the aforementioned embodiments, a completely different approach to a telescopic extension device. The telescopic extension device described therein is fixed neither on the support frame nor on the shelf, but used as a single part. The telescopic extension device is formed here on a horizontally extending pair of vertically spaced guide rods for guiding a retractable into the treatment room tray. This makes it possible, in contrast to the aforementioned embodiments, the telescopic extension device regardless of the shelf at any altitude to attach to a pair of guide rods. In this way it is possible to use the support frame very flexible; namely to insert commercial shelves directly into the support frame and adapted to the use of the telescopic extension device shelves, so shelves with a smaller width to hold by means of the telescopic extension device to the support frame. For this purpose, the shelves are loosely placed on the rails of the telescopic extension devices. Thus, the shelves do not tilt in the extended state from the treatment room in this embodiment, not single guide rods, but paired guide rods are used here, causing a stabilization of the loosely placed shelves in the vertical direction.

Der Erfindung stellt sich somit das Problem ein Haushaltgerät mit einer Teleskopauszugsvorrichtung zur Befestigung an einem in dem Behandlungsraum des Haushaltsgeräts angeordneten Traggestells anzugeben, die auf einfache Weise nachgerüstet werden kann und mit der die maximale lichte Höhe zwischen einzelnen, übereinander angeordneten Ablagen für die Nutzung zur Verfügung steht, auch wenn gleichzeitig direkt auf dem Traggestell eingeschobene Ablagen und auf der Teleskopauszugsvorrichtung aufgelegte Ablagen verwendet werden.The invention thus presents the problem of providing a household appliance with a telescopic extension device for attachment to a arranged in the treatment room of the household appliance support frame, which can be retrofitted in a simple manner and with the maximum clear height between each stacked shelves for use available stands, even if simultaneously inserted directly on the support frame shelves and placed on the telescopic extension device shelves.

Erfindungsgemäß wird dieses Problem durch ein Haushaltgerät mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a household appliance having the features of patent claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die Teleskopauszugsvorrichtung zeichnet sich überdies durch eine Nachrüstbarkeit aus. Die Teleskopauszugsvorrichtung kann ohne viel Aufwand auch an herkömmliche Traggestelle für in den Behandlungsraum einschiebbare Ablagen entnehmbar befestigt werden. Speziell ausgebildete Traggestelle sind nicht erforderlich. Ein weiterer Vorteil besteht darin, dass sich die Teleskopauszugsvorrichtung aus dem Behandlungsraum entfernen lässt, ohne gleichzeitig das Traggestell entfernen zu müssen. Hierdurch ist es möglich, auch fest und unlösbar mit der Behandlungsraumwand verbundene Traggestelle mit Teleskopauszugsvorrichtungen nachzurüsten. Darüber hinaus können die Teleskopauszugsvorrichtungen auch für den Pyrolysebetrieb eines als Backofen ausgebildeten Haushaltsgeräts mit Pyrolysereinigungsfunktion aus dem Behandlungsraum entfernt werden, während die Traggestelle für die Pyrolyse in dem Behandlungsraum verbleiben können. Ein besonderer Vorteil besteht darin, dass die gleiche Höhenlage für direkt in das Traggestell eingeschobene Ablagen und für Ablagen, die auf der an dem Traggestell montierten Teleskopauszugsvorrichtung aufliegen, benutzbar ist. Hierdurch ist gewährleistet, dass die maximale lichte Höhe zwischen einzelnen, übereinander angeordneten Ablagen für die Nutzung zur Verfügung steht, auch wenn gleichzeitig direkt auf dem Traggestell eingeschobene Ablagen und auf der Teleskopauszugsvorrichtung aufgelegte Ablagen verwendet werden.The telescopic extension device is also characterized by a retrofittability. The telescopic extension device can be removably attached to conventional support frames for retractable into the treatment room shelves. Specially trained carrying racks are not required. Another advantage is that the telescopic extension device can be removed from the treatment room, without having to remove the support frame at the same time. This makes it possible to retrofit also fixed and non-detachable connected to the treatment room wall supporting frames with telescopic extension devices. In addition, the telescopic extension devices can also be removed from the treatment room for pyrolysis operation of a household appliance designed as an oven with a pyrolysis cleaning function, while the support frames for pyrolysis can remain in the treatment room. A particular advantage is that the same altitude for directly inserted into the support frame shelves and for shelves that rest on the mounted on the support frame telescopic extension device, is usable. This ensures that the maximum clear height between individual superimposed shelves is available for use, even if simultaneously inserted directly on the support frame shelves and placed on the telescopic extension device shelves.

Eine besonders vorteilhafte Weiterbildung sieht vor, dass der Auflageabschnitt in der Einbaulage der Teleskopauszugsvorrichtung in den Zwischenraum der beiden Führungsstangen eingreift oder in dem Raum zwischen dem Paar Führungsstangen und der Behandlungsraumwand liegt. Hierdurch ist die Verwendung von herkömmlichen Ablagen für den direkten Einschub in das Traggestell ebenfalls für die Auflage auf die an dem Traggestell montierte Teleskopauszugsvorrichtung ermöglicht.A particularly advantageous development provides that the support section engages in the installation position of the telescopic extension device in the intermediate space of the two guide rods or in the space between the pair of guide rods and the treatment room wall. As a result, the use of conventional shelves for direct insertion into the support frame is also possible for support on the mounted on the support frame telescopic extension device.

Eine vorteilhafte Weiterbildung der vorgenannten Ausführungsform sieht vor, dass die Erhebung als ein längs der Laufschiene angeordnetes Winkelprofil mit einem L-förmigen Querschnitt ausgebildet ist, das mit einem Schenkel an der Laufschiene angeformt oder befestigt ist und an dessen anderem Schenkel der Auflageabschnitt angeordnet ist. Auf diese Weise ist die Teleskopauszugsvorrichtung konstruktiv einfach und robust realisiert.An advantageous development of the aforementioned embodiment provides that the survey is designed as an along the running rail arranged angle profile with an L-shaped cross-section which is integrally formed or fixed to a leg on the running rail and on the other leg of the support portion is arranged. In this way, the telescopic extension device is structurally simple and robust realized.

Eine andere vorteilhafte Weiterbildung sieht vor, dass die Dimensionen der Teleskopauszugsvorrichtung derart an den vertikalen Abstand zwischen dem Paar Führungsstangen angepasst sind, dass die Schienen mit Ausnahme der Erhebung und bezogen auf die Einbaulage der Teleskopauszugsvorrichtung lediglich außerhalb des zwischen den beiden Führungsstangen ausgebildeten Zwischenraums anordenbar sind. Hierdurch ist eine Fehlbedienung bei der Montage der Teleskopauszugsvorrichtung auf einfache Weise verhindert.Another advantageous embodiment provides that the dimensions of the telescopic extension device are adapted to the vertical distance between the pair of guide rods that the rails with the exception of the survey and based on the installation position of the telescopic extension device can be arranged only outside of the intermediate space formed between the two guide rods. As a result, incorrect operation during assembly of the telescopic extension device is prevented in a simple manner.

Grundsätzlich ist die Befestigungsvorrichtung der Teleskopauszugsvorrichtung nach Art, Dimension, Material und Anordnung in weiten geeigneten Grenzen wählbar. Vorteilhafterweise weist die Befestigungsvorrichtung einen Schnapp-, Rast- oder Klemmmechanismus auf. Hierdurch ist die Befestigungsvorrichtung konstruktiv einfach und robust realisiert.Basically, the fastening device of the telescopic extension device on the type, dimension, material and arrangement can be selected within wide suitable limits. Advantageously, the fastening device has a snap-action, latching or clamping mechanism. As a result, the fastening device is structurally simple and robust realized.

In Fig. 1 ist ein als Backofen ausgebildetes Haushaltsgerät mit einem als Garraum ausgebildeten Behandlungsraum 2 dargestellt. In dem Behandlungsraum 2 ist ein Traggestell 4 und ein an dem Traggestell 4 gehaltene Teleskopauszugsvorrichtung 6 angeordnet, wobei das Traggestell 4 auf dem Fachmann bekannte Weise lösbar an der Behandlungsraumwand 8 gehalten ist.In Fig. 1 is a trained as an oven home appliance with a designed as a cooking space treatment room 2 shown. In the treatment room 2, a support frame 4 and a held on the support frame 4 telescopic extension device 6 is arranged, wherein the support frame 4 is held in a manner known to those skilled releasably on the treatment chamber wall 8.

Das Traggestell 4 weist zwei voneinander beabstandete, vertikale Pfosten 10 auf, die über fünf horizontal verlaufende Paare 12 vertikal voneinander beabstandeter Führungsstangen 14 und 16 miteinander verbunden sind. Ein weiteres Traggestell 4 ist auf der gegenüberliegenden Seite des Behandlungsraums 2 und in Fig. 1 nicht sichtbar angeordnet. Somit ist es hier möglich, auf fünf Einschubebenen als Gargutträger ausgebildete Ablagen in den Behandlungsraum 2 einzuschieben.The support frame 4 has two spaced-apart, vertical posts 10, which are interconnected via five horizontally extending pairs 12 of vertically spaced guide rods 14 and 16. Another support frame 4 is on the opposite side of the treatment room 2 and in Fig. 1 not visible. Thus, it is possible here to insert shelves designed as a food support shelf into the treatment space 2 on five shelves.

Siehe hierzu Fig. 2, in der das Traggestell 4, eine Teleskopauszugsvorrichtung 6 sowie mehrere Ablagen 18 teilweise dargestellt sind. Wie aus Fig. 2 deutlich hervorgeht, können die Ablagen 18 entweder direkt auf dem Traggestell 4 aufgelegt werden, nämlich in dem Zwischenraum zwischen der oberen Führungsstange 14 und der unteren Führungsstange 16 eines Paares 12, oder auf eine Teleskopauszugsvorrichtung 6, die hier in der gleichen Höhenlage wie die zweite Einschubebene von unten, also das zweitunterste Paar 12 von Führungsstangen, angeordnet ist. Selbstverständlich ist es möglich, die Teleskopauszugsvorrichtung 6 in der gleichen Höhenlage zu jeder der in den Fig. 1 und 2 gezeigten Einschubebenen anzuordnen, was nachfolgend noch näher erläutert wird.See also Fig. 2 in which the support frame 4, a telescopic extension device 6 and a plurality of trays 18 are partially shown. How out Fig. 2 clearly shows the trays 18 can be placed either directly on the support frame 4, namely in the space between the upper guide rod 14 and the lower guide rod 16 of a pair 12, or on a telescopic extension device 6, here in the same altitude as the second insertion level from below, so the second lowest pair 12 of guide rods is arranged.

Dann wird die Teleskopauszugsvorrichtung 6 entlang der unteren Führungsstange 16 in den Behandlungsraum 2 hineingeschoben, bis das die zweigeteilte U-förmige Lasche 36 in Kontakt mit dem hinteren vertikalen Pfosten 10 kommt. Durch Fortführung der Bewegung umschnappt die zweigeteilte U-förmige Lasche 36 den hinteren vertikalen Pfosten 10. Gleichzeitig umschnappt die U-förmige Lasche 34 den vorderen vertikalen Pfosten 10 und der Benutzer kann die hakenartige Lasche 32 über die untere Führungsstange 16 haken.When transferring the telescopic extension device 6 in the in Fig. 1 shown installation position, this is threaded through the rear elbow 30 first on the lower guide rod 16 so that the two-part U-shaped tab 36, the lower guide rod 16 from above and below encloses. Then the telescopic extension device 6 is pushed along the lower guide rod 16 in the treatment room 2 until the two-part U-shaped tab 36 comes into contact with the rear vertical post 10. Continuing the movement, the two-part U-shaped tab 36 snaps over the rear vertical post 10. At the same time, the U-shaped tab 34 snaps over the front vertical post 10 and the user can hook the hook-like tab 32 over the lower guide bar 16.

Durch die Befestigungsvorrichtung mit dem vorderen und dem hinteren Winkelstück 28 und 30 ist die Teleskopauszugsvorrichtung 6 auf konstruktiv einfache und robuste Weise in deren Einbaulage an dem Traggestell 4 gehalten und in der Lage lösbar festgelegt.By the fastening device with the front and the rear angle piece 28 and 30, the telescopic extension device 6 is held in a structurally simple and robust manner in the installed position on the support frame 4 and releasably fixed in position.

An der Halteschiene 22 ist auf dem Fachmann bekannte Weise die innere Laufschiene 24 in Längsrichtung verschieblich gehalten. Auf der zu der Halteschiene 22 abgewandten Seite der inneren Laufschiene 24 ist die äußere Laufschiene 26 auf dem Fachmann bekannte Weise in Längsrichtung verschieblich gehalten, so dass sich die bereits erläuterte dreteilige Teleskopauszugsvorrichtung 6 ergibt. Siehe hierzu auch Fig. 6, in der aus Gründen der Übersichtlichkeit die Befestigungsvorrichtung weggelassen worden ist.On the retaining rail 22, the inner running rail 24 is held in the longitudinal direction displaceable manner known in the art. On the side facing away from the retaining rail 22 side of inner running rail 24, the outer runner 26 is slidably held in the longitudinal direction in a manner known to those skilled in the art, so as to give the already explained dreteilige telescopic extension device 6. See also Fig. 6 in which, for reasons of clarity, the fastening device has been omitted.

An der zu der inneren Laufschiene 24 abgewandten Seite der äußeren Laufschiene 26 ist eine als Winkelprofil mit L-förmigen Querschnitt ausgebildete Erhebung 38 befestigt, deren Form aus Fig. 6 noch deutlicher hervorgeht. Der eine Schenkel der Erhebung 38 ist als Befestigungsschenkel ausgebildet, mit dem die Erhebung 38 längs der äußeren Laufschiene 26 auf dem Fachmann bekannte Weise befestigt ist. Alternativ hierzu könnte der Befestigungsschenkel des Winkelprofils 38 auch an der äußeren Laufschiene 26 angeformt sein. An dem anderen Schenkel des Winkelprofils 38 ist ein Auflageabschnitt 40 ausgebildet, auf dem eine Ablage 18 aufgelegt werden kann. Siehe hierzu Fig. 2. Die Erhebung 38 ist dabei derart an der äußeren Laufschiene 26 angeordnet, dass die Erhebung 38 in der Einbaulage der Teleskopauszugsvorrichtung 6 eine Höhenlage zwischen der Oberseite der unteren Führungsstange 16 und der Unterseite der oberen Führungsstange 14 einnimmt. Siehe Fig. 1, 2 und 4.At the side facing away from the inner rail 24 side of the outer track rail 26 designed as an angle section with an L-shaped cross section survey 38 is fixed, the shape of Fig. 6 even clearer. The one leg of the survey 38 is formed as a mounting leg, with which the survey 38 is attached along the outer rail 26 in the art known manner. Alternatively, the mounting leg of the angle section 38 could also be integrally formed on the outer running rail 26. On the other leg of the angle section 38, a support portion 40 is formed, on which a tray 18 can be placed. See also Fig. 2 , The survey 38 is arranged on the outer running rail 26 such that the survey 38 in the installed position of the telescopic extension device 6 assumes an altitude between the top of the lower guide rod 16 and the underside of the upper guide rod 14. Please refer Fig. 1, 2 and 4 ,

Bei dem vorliegenden Ausführungsbeispiel greift der Auflageabschnitt 40 der Erhebung 38 in der Einbaulage der Teleskopauszugsvorrichtung 6 in den Zwischenraum der beiden Führungsstangen 14 und 16 ein, so dass auch herkömmliche Ablagen 18 verwendet werden können, die zum direkten Einschub in das Traggestell 4 ausgebildet sind. Siehe auch die Fig. 1 bis 4. Der gleiche Vorteil besteht auch dann, wenn der Auflageabschnitt 40 stattdessen zwischen dem Paar 12 und der Behandlungsraumwand 8 liegt.In the present embodiment, the support portion 40 of the survey 38 engages in the installation position of the telescopic extension device 6 in the space between the two guide rods 14 and 16, so that conventional shelves 18 can be used, which are designed for direct insertion into the support frame 4. See also the Fig. 1 to 4 , The same advantage exists even if the support section 40 instead lies between the pair 12 and the treatment chamber wall 8.

Um Fehlbedienungen zu verhindern, sind die Dimensionen der Teleskopauszugsvorrichtung 6 derart an den Zwischenraum, also den vertikalen Abstand zwischen dem Paar Führungsstangen 14, 16 angepasst, dass die Schienen 22, 24 und 26 mit Ausnahme der Erhebung 38 und bezogen auf die Einbaulage der Teleskopauszugsvorrichtung 6 lediglich außerhalb des zwischen den beiden Führungsstangen 14, 16 ausgebildeten Zwischenraums anordenbar sind. Siehe hierzu auch Fig. 1 und 4.In order to prevent incorrect operation, the dimensions of the telescopic extension device 6 are adapted to the intermediate space, ie the vertical distance between the pair of guide rods 14, 16, that the rails 22, 24 and 26 with the exception of the survey 38 and based on the installation position of the telescopic extension device. 6 can be arranged only outside of the intermediate space formed between the two guide rods 14, 16. See also Fig. 1 and 4 ,

Abweichend von dem vorliegenden Ausführungsbeispiel sind auch andere dem Fachmann bekannte und geeignete Befestigungsvorrichtungen denkbar. Ferner ist die Zahl der Einschubebenen nicht auf fünf beschränkt, sondern kann kleiner oder größer sein. Anstelle einer dreiteiligen Teleskopauszugsvorrichtung 6 ist beispielsweise auch eine zweiteilige Teleskopauszugsvorrichtung denkbar, die analog zu der dreiteiligen Ausführungsform 6 ausgebildet ist. Es entfällt lediglich die innere Laufschiene 24, so dass die äußere Laufschiene 26 mit dem oben erläuterten Aufbau, insbesondere mit der Erhebung 38, direkt an der Halteschiene 22 verschieblich gehalten wäre. Der Auflagenabschnitt ist ebenfalls nach Art und Dimension in weiten geeigneten Grenzen wählbar. Beispielsweise wäre es auch möglich, dass die Erhebung nicht durchgehend ausgebildet ist, sondern aus zwei einzelnen Auflageböcken besteht, die an dem vorderen und dem hinteren Ende der Laufschiene 26 angeordnet sind. In der Einbaulage der Teleskopauszugsvorrichtung 6 greifen diese Auflageböcke in den Raum zwischen den beiden Führungsstangen 14, 16 und der seitlichen Behandlungsraumwand 8 ein.Deviating from the present embodiment, other known and suitable to those skilled fastening devices are conceivable. Further, the number of shelf levels is not limited to five, but may be smaller or larger. Instead of a three-part telescopic extension device 6, for example, a two-part telescopic extension device is conceivable, which is formed analogously to the three-part embodiment 6. It only eliminates the inner rail 24, so that the outer rail 26 would be held with the above-mentioned structure, in particular with the survey 38, slidable directly on the support rail 22. The edition section is also on the type and Dimension selectable within wide suitable limits. For example, it would also be possible that the survey is not continuous, but consists of two individual support blocks, which are arranged at the front and the rear end of the track rail 26. In the installed position of the telescopic extension device 6, these support blocks engage in the space between the two guide rods 14, 16 and the lateral treatment chamber wall 8.

Darüber hinaus ist die Verwendung der Teleskopauszugsvorrichtung nicht auf Backöfen oder Gargeräte beschränkt. Eine Verwendung ist grundsätzlich bei allen Haushaltsgeräten mit einem Behandlungsraum möglich. Beispielsweise sind dies Herde, Dampfgargeräte, Mikrowellengeräte, Kühlmöbel oder Geschirrspülmaschinen.In addition, the use of the telescopic extension device is not limited to ovens or cooking appliances. A use is basically possible with all household appliances with a treatment room. For example, these are stoves, Dampfgargeräte, microwave ovens, refrigerators or dishwashers.
