Description

Die Erfindung bezieht sich auf eine Backofentür zum Verschließen der Beschickungsöffnung des Garraumes eines Backofens, mit einer äußeren, frontseitigen Glasscheibe und mit wenigstens einer weiteren, dem Garraum zugewandten Glasscheibe, welche Glasscheiben an einem im wesentlichen metallischen Türrahmen randseitig, mindestens eine der Glasscheiben von Teilen des Türrahmens randseitig umfassend, auf elastischen Lagerelementen gelagert sind.
Die GB 2 198 621 A beschreibt eine Backofentür mit einer Außenscheibe und einer Innenscheibe. Ein Dichtelement umschließt die Innenscheibe in U-Form entlang ihres Umfangs.
Bei einer weiteren bekannten Backofentür mit Innenscheibe aus Borosilikat-Glas ( DE 10 007 923 C1 ) besitzt die Backofentür eine frontseitige, äußere, großflächige Glasscheibe und an der dem Garraum zu gewandten Seite eine innere ebenfalls großflächige Glasscheibe aus Borosilikat-Material. Beide Glasscheiben sind an einem metallischen Türrahmen gehalten. Hierbei ist besonders die innere Glasscheibe zum Teil auf elastischen Lagerelementen gelagert. Zumindest einer oder einigen der Glasscheiben sind üblicher Weise die Glasscheibe umgreifende metallische Teile wie z. B. eine am oberen Scheibenrand angeordnete, den Hohlraum im Scheibenverbund abschließende Blende benachbart. Derartige elastische Lagerelemente bestehen z. B. aus mehreren in den seitlichen, senkrechten Holmen des metallischen Türrahmens eingesetzten Gummi- bzw. Silikonpropfen, auf denen sich die seitlichen Scheibenränder abstützen. Die Positionierung und Befestigung dieser Lagerelemente erfordern einen beträchtlichen Montageaufwand. Sie können nicht zuverlässig verhindern, dass die betreffende Glasscheibe bei ruckartigen Türbewegungen z. B. bei einer schnellen Schließbewegung, aufgrund eines temperaturbedingt, notwendigen Lagerspieles bzw. aufgrund ihrer elastisch nachgiebigen Halterung mit Teilen des Türrahmens z. B. mit der genannten oberen Blende in Berührung kommen, verbunden mit einem unerwünschten Klappergeräusch. Hinzu kommt, dass die bei Backöfen und insbesondere bei mit einer Einrichtung zur pyrolytischen Selbstreinigung mit Garraum-Temperaturen bis 400°C bzw. bis ca. 320°C im oberen Bereich der inneren Glasscheibe verwendeten Glasmaterialien z. B. Borosilikat-Glas sehr bruchempfindlich sind, insbesondere am Scheibenrand, der während der Montage oder bei ruckartigen Türbewegungen, harten Stößen ausgesetzt sein kann.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Backofentür der eingangs genannten Art so auszugestalten, dass in montagefreundlicher Weise eine Lagerung zumindest einer der Glasscheiben erreicht wird, durch welche diese Glasscheibe vor ungünstigen äußeren Einflüssen, wie Erschütterungen, Hochtemperatur oder dergleichen geschützt im Scheibenverbund der Backofentür gehalten ist.
Diese Aufgabe wird erfindungsgemäß bei einer Backofentür der eingangs genannten Art durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Durch die erfindungsgemäß Lagerung einer der Glasscheiben, nämlich der Inneren, dem Garraum unmittelbar zugewandten Glasscheibe ergeben sich mehrfache Vorteile in bezug auf die Montage der Backofentür und hinsichtlich des Betriebes des Backofens z. B. eines pyrolytisch selbstreinigenden Backofens. Die beidseitige Anordnung von elastischen Lagerelementen gibt der betreffenden bruchempfindlichen Glasscheibe insbesondere am empfindlichen Scheibenrand einen wesentlichen Schutz beim Transport, bei der Montage oder Demontage dieser Glasscheibe gerade am stoßempfindlichen Scheibenrand. Insbesondere die Montage wird dadurch wesentlich vereinfacht, dass die wesentlichen Lagerelemente durch entsprechende Vormontage unmittelbarer Bestandteil der Glasscheibe sind und keine anderen, separaten Lagerelemente im Lagebereich der erfindungsgemäßen Lagerelemente mehr benötigt werden. Insbesondere erfolgt eine elastische Lagerung der betreffenden Glasscheibe auch dort, wo externe, separate Lagerelemente im Bereich von Teilen des metallischen Türrahmens, die die Glasscheibe umgreifen und mit einer Begrenzungskante unmittelbar am Scheibenrand enden, nur schwer anzubringen sind. In vorteilhafter Weise anwendbar ist die erfindungsgemäße Türlagerung an der dem Garraum unmittelbar zugewandten Innenscheibe der Backofentür, da in aller Regel der Randbereich dieser inneren Glasscheibe von metallischen Teilen des Türrahmens umgriffen wird und da bei Betrieb des Backofens und insbesondere bei pyrolytischem Selbstreinigungsbetrieb an dieser inneren Glasscheibe und dort insbesondere am oberen Scheibenrand extrem hohe Temperaturen auftreten und infolgedessen Toleranzfragen im Bezug auf eine erhöhte Materialausdehnung von Bedeutung sind und auf der anderen Seite eine bestmögliche Abdichtung des Scheibenrandes zur Verhinderung von Wärmeleckstellen angestrebt wird. Der Türrahmen kann auch durch zumindest 2 Einzelprofile gebildet sein, die vertikal hinter der Frontscheibe in an sich bekannter Weise angeordnet sind.The invention relates to a baking oven door for closing the feed opening of the cooking chamber of a baking oven, with an outer front glass pane and at least one further, the cooking chamber facing glass, which glass panes on a substantially metallic door frame edge, at least one of the glass panes of parts of Door frame edge comprehensive, are mounted on elastic bearing elements.
The GB 2 198 621 A describes a oven door with an outer pane and an inner pane. A sealing element surrounds the inner pane in a U-shape along its circumference.
In another known oven door with borosilicate glass inner pane ( DE 10 007 923 C1 ) has the oven door front, outer, large-scale glass and on the cooking chamber to the side facing an inner also large-scale glass of borosilicate material. Both glass panes are held on a metallic door frame. In this case, in particular the inner glass pane is partly supported on elastic bearing elements. At least one or some of the glass panes are usually the glass pane encompassing metallic parts such. B. a arranged at the upper edge of the disc, adjacent to the cavity in the disc composite aperture. Such elastic bearing elements consist z. B. from several inserted in the lateral, vertical bars of the metallic door frame rubber or silicone plugs on which the lateral disc edges are supported. The positioning and mounting of these bearing elements require a considerable installation effort. You can not reliably prevent the glass in question jerky door movements z. B. in a fast closing movement, due to a temperature-related, necessary bearing clearance or due to their resilient mounting with parts of the door frame z. B. come into contact with said upper panel, associated with an undesirable rattling noise. In addition, the glass materials used in ovens and in particular with a device for pyrolytic self-cleaning with oven temperatures up to 400 ° C and up to about 320 ° C in the upper region of the inner glass z. As borosilicate glass are very sensitive to breakage, especially on the edge of the disc, which may be exposed to hard shocks during assembly or jerky door movements.
The present invention has for its object to provide an oven door of the type mentioned in such a way that a mounting of at least one of the glass sheets is achieved in a montage friendly manner, through which this glass from unfavorable external influences, such as shocks, high temperature or the like protected in the laminated pane of the oven door is held.
This object is achieved with a oven door of the type mentioned by the characterizing features of claim 1. The inventive storage of one of the glass panes, namely the interior, the cooking chamber directly facing glass resulting in multiple advantages with respect to the assembly of the oven door and in terms of the operation of the oven z. B. a pyrolytic self-cleaning oven. The two-sided arrangement of elastic bearing elements gives the relevant fracture-sensitive glass pane, in particular on the sensitive edge of the pane, a substantial protection during transport, during assembly or disassembly of this glass pane, especially on the impact-sensitive pane edge. In particular, the assembly is substantially simplified, that the essential bearing elements by appropriate pre-assembly are an integral part of the glass and no other, separate bearing elements in the position range of the bearing elements according to the invention are more needed. In particular, an elastic mounting of the relevant glass also takes place where external, separate bearing elements in the region of parts of the metallic door frame, which surround the glass and end with a boundary edge directly on the edge of the disc, are difficult to install. Advantageously, the inventive door storage on the cooking chamber directly facing inner pane of the oven door, since usually the edge region of this inner glass pane is encompassed by metallic parts of the door frame and there during operation of the oven and in particular in pyrolytic self-cleaning operation of this inner glass and There particularly at the upper edge of the disc extremely high temperatures occur and as a result, tolerance issues related to increased material expansion are important and, on the other hand, the best possible sealing of the wafer edge to prevent heat leakage is sought. The door frame can also be formed by at least 2 individual profiles, which are arranged vertically behind the windscreen in a conventional manner.

Gemäß der Erfindung ist mindestens ein Lagerelement im wesentlichen U-förmig ausgebildet und umfasst den Scheibenrand an gegenüberliegenden Scheibenflächen und an der Scheibenstirnkante mit elastischer Vorspannung. Auf diese Weise wird die Montage der beidseitigen Lagerelemente wesentlich vereinfacht und man erhält auch an der bruchempfindlichen Stirnkante der betreffenden Glasscheibe ein elastisches Lager, also insgesamt neben den vorteilhaften Lagereigenschaften zusätzlich einen wirksamen Kantenschutz der betreffenden Glasscheibe. Das Lagerelement ist aus einem vorzugsweise hochtemperaturfesten elastischen Kunststoff wie Silikon oder dergleichen gebildet, so dass die Verwendung solcher Lagerelemente auch bei pyrolytisch selbstreinigenden Backöfen mit Hochtemperaturbetrieb problemlos möglich ist. Jedoch können derartige Lagerelemente auch aus einem anderen Material hergestellt sein, z. B. aus Federstahl.According to the invention, at least one bearing element is formed substantially U-shaped and comprises the disc edge on opposite disc surfaces and on the disc end edge with elastic bias. In this way, the mounting of the two-sided bearing elements is substantially simplified and obtained also on the fracture-sensitive front edge of the glass pane in question an elastic bearing, so in addition to the advantageous storage properties in addition to effective edge protection of the relevant glass. The bearing element is formed from a preferably high temperature resistant elastic plastic such as silicone or the like, so that the use of such bearing elements is easily possible even with pyrolytic self-cleaning ovens with high temperature operation. However, such bearing elements may also be made of a different material, for. B. spring steel.

Gemäß der Erfindung besitzt das im wesentlichen U-förmige und von einem Teil des Türrahmens umfasste Lagerelement am Ende eines freien Schenkels einen nasenartigen Ansatz, der sich an einer Begrenzungskante des umfassenden Teils des Türrahmens abzustützen vermag. Durch diesen nasenartigen Ansatz wird verhindert, dass etwa bei der Durchführung von Reinigungsarbeiten das auf den Scheibenrand aufgesteckte Lagerelement aus der Sollposition verschoben wird und hinter die Begrenzungskante des erwähnten umfassenden Teils des Türrahmens gerät bzw. dahinter verschwindet.According to the invention, the substantially U-shaped bearing element enclosed by a part of the door frame has at the end of a free leg a nose-like projection which is able to bear against a boundary edge of the comprehensive part of the door frame. Through this nose-like approach prevents the mounted on the disc edge bearing element is displaced from the desired position and approximately behind the boundary edge of said comprehensive part of the door frame device or disappears behind about when performing cleaning work.

Aufgrund der U-förmigen Ausbildung des Lagerelementes erhält man eine besonders einfache Montage der selben, da gemäß einer Weiterbildung der Erfindung das Lagerelement formschlüssig verklemmend auf den Scheibenrand aufsteckbar ist, wobei die Montage der Lagerelemente noch dadurch erleichtert wird, dass gemäß einer Weiterbildung der Erfindung das U-förmige Lagerelement ungleich lange freie Schenkel der U-Form besitzt.Due to the U-shaped design of the bearing element to obtain a particularly simple installation of the same, since according to a development of the invention, the bearing element is positively clamped clamped on the disc edge is plugged, the assembly of the bearing elements is further facilitated by the fact that according to a development of the invention U-shaped bearing element has unequal length free legs of the U-shape.

In bevorzugter Weise überzieht das Lagerelement zumindest eine gesamte Seite der rechteckförmigen Glasscheibe, wobei selbstverständlich am Scheibenrand auch mehrere kürzere Lagerelemente aufgebracht werden können, die ebenfalls die erwähnten Vorteile hinsichtlich der Lagerung der Glasscheibe und des Kantenschutzes ergeben.In a preferred manner, the bearing element covers at least an entire side of the rectangular glass pane, it being understood that several shorter bearing elements can be applied to the edge of the pane, which also results in the mentioned advantages with respect to the mounting of the glass pane and the edge protection.

Gemäß einer bevorzugten Ausführungsform ist das wenigstens ein Lageelement am oberen Scheibenrand vorzugsweise der dem Garraum unmittelbar zugewandten Glasscheibe angeordnet und stützt sich mit dem einen Schenkel oder Lagerelement-Teil an dem Türrahmen elastisch ab und stellt mit dem gegenüberliegenden Schenkel oder Lagerelement-Teil für eine die Backofentür an der Oberseite abschließende und die genannte Glasscheibe übergreifende Blende ein elastisches Lager dar.According to a preferred embodiment, the at least one layer element is preferably arranged at the upper edge of the glass pane directly facing the cooking chamber and is supported elastically with the one leg or bearing element part on the door frame and provides with the opposite leg or bearing element part for a the oven door closing at the top and the said glass plate cross aperture is an elastic bearing.

Die Backofentür gem. Fig. 1 und 2 besitzt als tragenden Teil einen metallischen Türrahmen 1, im wesentlichen gebildet aus zwei senkrechten und beispielsweise U-förmigen Holmen zu beiden Seiten einer Beschickungsöffnung des nicht dargestellten Backofens, welche Beschickungsöffnung durch die Backofentür verschlossen werden soll. Die vorgenannten Holme sind durch ebenfalls nicht dargestellte Querstreben miteinander rahmenartig verbunden. An diesem Türrahmen 1 ist an der Außenseite der Backofentür eine äußere, ebene Glasscheibe 2 in nicht näher beschriebener Weise befestigt, z. B. mittels Klebeverbindungen, während an der gegenüberliegenden Seite des Türrahmens 1 eine innere, dem Garraum des Backofens unmittelbar zugewandte Glasscheibe 3 gelagert ist, die im Anschluss an ebene, flächige Scheibenränder 4 zum Garraum hin mit einer Auswölbung 5 versehen ist. Zwischen den beiden Glasscheiben 2 und 3 ist ein Hohlraum 6 gebildet, der z. B. zur Durchführung eines Kühlluftstromes dient und der nach oben hin verschlossen ist durch eine dachförmige Blende 7 (siehe insbesondere Fig. 2), welche z. B. aus Edelstahl gebildete Blende 7 mit einem senkrechten Schenkel 8 den oberen Scheibenrand 4 der inneren Glasscheibe 3 leicht übergreift und in unmittelbarer Nähe dieser Glasscheibe 3 endet. Wie die Figuren, insbesondere Fig. 2, zeigen ist auf den oberen Scheibenrand 4 der Glasscheibe 3 ein einstückiges Lagerelement 9 selbstklemmend aufgesteckt, welches Lagerelement 9 in Fig. 3 als Einzelheit gezeigt ist. Selbstverständlich kann ein solches Lagerelement 9 oder aber kürzere Lagerelement-Teile an mehreren oder allen Scheibenrändern 4 der Glasscheibe 3 aufgebracht sein. Beim Ausführungsbeispiel besteht das die gesamte obere Seite der rechteckförmigen Glasscheibe 3 überziehende Lagerelement 9 aus einem elastischen, hochtemperaturfesten Kunststoff wie z. B. Silikon. Die vorgenannte Selbstklemmung wird dadurch erreicht, wie Fig. 3 zeigt, dass das Lagerelement 9 im wesentlichen U-förmig ausgebildet ist, wobei die freien Schenkel 10 und 11 um den Winkel a gegeneinander geneigt verlaufen und über den unfreien Schenkel 12 miteinander verbunden sind. Hierbei ist der eine Schenkel 11 etwas länger als der gegenüberliegende Schenkel 10, wodurch die Montage des Lagerelementes 9, d. h. das Aufstecken des Lagerelementes 9 auf die Stirnkante der Glasscheibe 3 wesentlich erleichtert wird. Beim Ausführungsbeispiel am kürzeren Schenkel 10 ist angeformt ein nasenartiger Ansatz 13, der sich in unmittelbarer Nähe des Endes des senkrechten Schenkels 8 der Blende 7 befindet und dieses Ende geringfügig überragt, wie Fig. 2 zeigt, sodass ein unbeabsichtigtes Verschieben des Lagerelementes 9 z. B. bei Reinigungsarbeiten im Beispiel nach oben hin, also hinter den unteren Rand der Blende 7 verhindert wird, da dieser nasenartige Ansatz 13 sich am unteren Ende der Blende 7 abzustützen vermag. Wie insbesondere Fig. 2 zeigt, bildet das Lagerelement 9 mit den Schenkeln 10 und 11 beidseitig des Scheibenrandes 4 der Glasscheibe 3 elastische Lager, mit denen sie sich einerseits elastisch auf den Türrahmen 1 abstützt und andererseits ein elastisches Lager für das untere Ende der den Scheibenrand 4 umgreifende Blende 7, 8 bildet, so dass z. B. beim ruckartigen Schließen der Backofentür ein harter, ein Klappergeräusch hervorrufender Kontakt zwischen Scheibenrand 4 und Blende 7 bzw. deren Schenkel 8 mit Sicherheit vermieden wird. Das beschriebene Lagerelement 9 bildet also zumindest im oberen Bereich der Backofentür wirksame elastische Lager für die betreffende Glasscheibe 3 und stellt gleichzeitig einen wirksamen Kantenschutz für die Glasscheibe dar, gerade an den besonders bruchempfindlichen Scheibenkanten. Wie Fig. 1 zeigt, sind an dem metallischen Türrahmen 1 Verbindungs- oder Scharnierteile 14 angeordnet, für die z. B. drehbare Verbindung mit der nicht gezeigten Ofenmuffel des Backofens.The oven door gem. Fig. 1 and 2 has as a supporting part of a metallic door frame 1, formed essentially of two vertical and, for example, U-shaped bars on both sides of a feed opening of the oven, not shown, which feed opening to be closed by the oven door. The aforementioned spars are connected to each other like a frame by cross members, also not shown. At this door frame 1 is attached to the outside of the oven door an outer, flat glass pane 2 in unspecified manner, z. B. by means of adhesive bonds, while on the opposite side of the door frame. 1 an inner, the cooking chamber of the oven directly facing glass pane 3 is mounted, which in connection to flat, flat disc edges 4 to the cooking chamber out with a Bulge 5 is provided. Between the two glass sheets 2 and 3, a cavity 6 is formed, the z. B. is used to carry out a cooling air flow and is closed at the top by a roof-shaped aperture 7 (see in particular Fig. 2 ), which z. B. made of stainless steel aperture 7 with a vertical leg 8, the upper edge of the disc 4 of the inner glass pane 3 slightly overlaps and ends in the immediate vicinity of this glass sheet 3. Like the characters, in particular Fig. 2 , Show is on the upper edge of the disc 4 of the glass 3, a one-piece bearing element 9 self-clamping attached, which bearing element 9 in Fig. 3 is shown as a detail. Of course, such a bearing element 9 or shorter bearing element parts may be applied to several or all the disc edges 4 of the glass pane 3. In the embodiment, the entire upper side of the rectangular glass plate 3 covering bearing element 9 consists of an elastic, high temperature resistant plastic such. Silicone. The aforementioned self-clamping is achieved by how Fig. 3 shows that the bearing element 9 is formed substantially U-shaped, wherein the free legs 10 and 11 are inclined by the angle a against each other and are connected to each other via the non-free leg 12. Here, the one leg 11 is slightly longer than the opposite leg 10, whereby the mounting of the bearing element 9, that is, the attachment of the bearing element 9 on the front edge of the glass sheet 3 is substantially facilitated. In the embodiment of the shorter leg 10 is formed a nose-like projection 13, which is located in the immediate vicinity of the end of the vertical leg 8 of the panel 7 and slightly surmounted by this end, like Fig. 2 shows, so that unintentional displacement of the bearing element 9 z. B. in cleaning work in the example upwards, so behind the lower edge of the panel 7 is prevented because this nose-like approach 13 is able to support itself at the lower end of the panel 7. In particular Fig. 2 shows, the bearing element 9 forms with the legs 10 and 11 on both sides of the disc edge 4 of the glass 3 elastic bearings, with which it is elastically supported on the one hand on the door frame 1 and on the other hand an elastic bearing for the lower end of the disc rim 4 embracing aperture 7, 8 forms, so that z. B. in the jerky closing of the oven door a hard, a rattling noise inducing contact between the disc edge 4 and aperture 7 and the leg 8 is avoided with certainty. The described bearing element 9 thus forms at least in the upper region of the oven door effective elastic bearings for the relevant glass pane 3 and at the same time represents an effective edge protection for the glass, especially to the particular fracture-sensitive window edges. As Fig. 1 shows, 1 connecting or hinge parts 14 are arranged on the metallic door frame, for the z. B. rotatable connection with the oven muffle oven, not shown.
