Abstract

Oven door has two glass or glass ceramic panels (2,3) spaced apart, transparent front panel (2) and shaped inner panel (3) facing loading opening. Inner panel has linear base (3a) with both sides of 30 to 40 mm (3b,3c), angled at 45 to 60 degrees. Angled section compensates for distortion due to heat, so oven door lies snug to oven muffle or muffle sealing.

Description

Die Erfindung bezieht sich auf eine Backofentür zum Verschließen der Beschickungsöffnung der Ofenmuffel eines Backofens, bestehend aus einem metallischen Türrahmen, in dem mindestens zwei beabstandet nebeneinander angeordnete Glas- und/oder Glaskeramikscheiben gehaltert sind, eine zumindest in Teilbereichen transparente Frontscheibe und eine der Beschickungsöffnung zugewandte verformte Innenscheibe.The invention relates to an oven door for closing the Loading opening of the oven muffle of an oven, consisting of a metallic door frame in which at least two spaced apart arranged glass and / or glass ceramic disks are held, a at least in parts of the transparent windscreen and one of the Deformed inner pane facing the loading opening.

Innerhalb der Backofenmuffel eines Backofens, insbesondere wenn es sich um einen Backofen mit pyrolytischer Selbstreinigung handelt, treten im Betrieb typischerweise sehr hohe Temperaturen auf. Dabei sind die an der Innenscheibe zu messenden Temperaturen im Zentralbereich wesentlich höher als im äußeren Bereich bzw. dem peripheren Bereich. Dadurch entsteht ein großer Temperaturgradient in der Innenscheibe vom Zentralbereich zum Peripheriebereich. Dieser Temperaturgradient bewirkt, daß sich die Innenscheibe wölbend verformt, was nachteiligerweise dazu führen kann, daß die Innenscheibe bei Drehtüren im unteren Muffelbereich von der Muffel bzw. der zugehörigen Muffeldichtung weggedrückt wird, was zu einem Türspalt führt, aus dem Wärme aus der Ofenmuffel entweichen kann.Inside the oven muffle of an oven, especially if it is an oven with pyrolytic self-cleaning occurs in operation typically very high temperatures. They are at the Temperatures to be measured in the central area are significantly higher than in the outer area or the peripheral area. This creates a large temperature gradient in the inner pane from the central area to the O area. This temperature gradient causes the The inner pane is arched, which can disadvantageously lead to the fact that the inner pane for revolving doors in the lower muffle area from the muffle or the associated muffle seal is pushed away, resulting in a door gap leads from which heat can escape from the furnace muffle.

Es sind mehrere konstruktive Maßnahmen zur Lösung dieser Problematik bekannt. There are several constructive measures to solve this problem known.

So zeigt die DE 198 49 989 A1 eine Backofentür, bei der die Innenscheibe derart schalenförmig gewölbt ist, daß ihr Abstand von der durch den Muffelflansch aufgespannten Ebene im Zentralbereich größer als in deren Peripheriebereich ist, wodurch die betrieblich auftretende Verformung kompensiert wird.For example, DE 198 49 989 A1 shows an oven door in which the inner pane is so cupped that its distance from that by the Muffle flange spanned level in the central area larger than in their Peripheral area is, causing the operationally occurring deformation is compensated.

Eine derartige, definiert schalenförmig gewölbte Innenscheibe ist nur mit hohem Aufwand herzustellen, insbesondere da die Wölbung im mm-Bereich (5 - 15/10 mm) liegt.Such a, defined bowl-shaped inner pane is only with high effort to manufacture, especially since the curvature in the mm range (5 - 15/10 mm).

Der Erfindung liegt die Aufgabe zugrunde, für die eingangs bezeichnete Backofentür zum Verschließen der Beschickungsöffnung der Ofenmuffel eines Backofens, bestehend aus einem Türrahmen, in dem mindestens zwei beabstandet nebeneinander angeordnete Glas- und/oder Glaskeramikscheiben gehaltert sind, eine zumindest in Teilbereichen transparente Frontscheibe und eine der Beschickungsöffnung zugewandte verformte Innenscheibe, eine mit geringerem Aufwand verformbare Innenscheibe bereitzustellen.The invention is based, for the above-mentioned task Oven door to close the loading opening of the oven muffle Oven consisting of a door frame in which at least two spaced apart glass and / or glass ceramic panes are held, a windshield that is transparent at least in some areas and a deformed inner pane facing the loading opening, one with Provide deformable inner pane with less effort.

Die Lösung dieser Aufgabe gelingt gemäß der Erfindung dadurch, daß die Innenscheibe einen linearen Basisschenkel mit an beiden Enden zur Innenscheibe hin abgewinkelten Seitenschenkeln aufweist.This object is achieved according to the invention in that the Inner pane a linear base leg with at both ends Has inner disc angled side legs.

Eine derart verformte Winkel-Innenscheibe ist mit den aus der Herstellung von Kamin- und Ofentüren bekannten Methoden verhältnismäßig einfach und mit definierten Abmessungen herzustellen.Such a deformed angle inner pane is with those from the manufacture of Chimney and stove doors known methods relatively simple and with to produce defined dimensions.

Durch die winklige Verformung wird dabei die durch den betrieblich auftretenden Temperaturgradienten bedingte Verformung wirksam kompensiert, so daß die Backofentür betrieblich immer dicht an der Backofenmuffel bzw. der Backofenmuffel-Dichtung anliegt. Due to the angular deformation, the operational occurring temperature gradients effectively compensated for deformation, so that the oven door is always close to the oven muffle or the oven muffle seal is in contact.

Der Türrahmen besteht vorzugsweise aus einem metallischen Werkstoff. Es sind aber auch Türrahmen aus Kunststoff oder Holz bekannt.The door frame is preferably made of a metallic material. It but also door frames made of plastic or wood are known.

Die Kompensation ist besonders günstig, wenn die beiden Biegewinkel jeweils im Bereich von 45° - 60° liegen sowie die Länge der Seitenschenkel im Bereich von 30 - 40 mm liegt.The compensation is particularly favorable if the two bending angles are in each case are in the range of 45 ° - 60 ° and the length of the side legs in the Range of 30 - 40 mm.

Konstruktiv ist es vorteilhaft, wenn die Biegekanten betrieblich vertikal verlaufen. Die Unterbringung der anderen Türkomponenten ist dann unproblematisch. Ebenso ist die Rahmenkonstruktion relativ einfach.In terms of construction, it is advantageous if the bending edges are operationally vertical run. The housing of the other door components is then unproblematic. The frame construction is also relatively simple.

Grundsätzlich kann der Einbau der Innenscheibe auch so getroffen sein, daß die Biegekanten betrieblich horizontal verlaufen.Basically, the installation of the inner pane can also be made such that the bending edges run horizontally during operation.

Anhand eines in der Zeichnung in einer einzigen Figur dargestellten Ausführungsbeispieles wird die Erfindung näher beschrieben. Die einzige Figur zeigt in zwei Ansichten, einer Draufsicht auf die Oberseite und einer Frontansicht der Backofentür, schematisch den Aufbau der erfindungsgemäß verformten Innenscheibe.Using one shown in the drawing in a single figure The embodiment is described in more detail. The only figure shows in two views, a top view of the top and one Front view of the oven door, schematically the structure of the invention deformed inner pane.

Die Backofentür weist einen Halterahmen 1 aus Metall mit einem möglichst geringen Wärme-Ausdehnungskoeffizienten auf, in dem eine Frontscheibe 2 und eine verformte Innenscheibe 3 gehaltert sind. Die Frontscheibe besteht typischerweise aus einem thermisch sehr stabilen Glas, während die Innenscheibe 3 vorzugsweise aus Glaskeramik besteht. Weiterhin ist in der Draufsicht ein Türgriff 4 zum Öffnen und Schließen der Backofentür zu erkennen.The oven door has a holding frame 1 made of metal with a possible low coefficient of thermal expansion in which a windshield 2 and a deformed inner pane 3 are held. The windscreen is there typically from a thermally very stable glass, while the Inner pane 3 preferably consists of glass ceramic. Furthermore, in the Top view of a door handle 4 for opening and closing the oven door detect.

Die Innenscheibe ist, anders als beim Stand der Technik, nicht schalenförmig verformt, sondern weist einen linearen Basisschenkel 3 a mit an beiden Enden zur Frontscheibe 2 hin abgewinkelten Seitenschenkeln 3 b und 3 c auf. Die Biegewinkel liegen dabei vorzugsweise im Bereich von 45° - 60°. Die Länge der Seitenschenkel beträgt dabei typischerweise 30 - 40 mm.In contrast to the prior art, the inner pane is not bowl-shaped deformed, but has a linear base leg 3 a with at both ends to the front window 2 angled side legs 3 b and 3 c. The Bending angles are preferably in the range of 45 ° -60 °. The length the side leg is typically 30-40 mm.

Vorzugsweise ist, wie in der Fig. dargestellt, die Innenscheibe 3 so montiert, daß die Biegekanten 3 d, 3 e im eingebauten Zustand der Backofentür vertikal verlaufen. Bei einer derartigen Anordnung entstehen keine räumlichen Probleme hinsichtlich der Anbringung der Türscharniere und des Schließmechanismus. Auch ist die Rahmenkonstruktion einfacher.Preferably, as shown in the figure, the inner pane 3 is mounted that the bending edges 3 d, 3 e vertically in the installed state of the oven door run. With such an arrangement there are no spatial ones Problems with the installation of the door hinges and the Closing mechanism. The frame construction is also simpler.

Prinzipiell ist es jedoch auch denkbar, die Innenscheibe so zu montieren, daß die Biegekanten im eingebauten Zustand der Backofentür horizontal verlaufen.In principle, however, it is also conceivable to mount the inner pane in such a way that the bending edges run horizontally when the oven door is installed.
