Abstract

The insulating glass element (10) has two viewing windows (11,12) made of transparent glass or glass ceramic material, where a visual region is partially formed in an area of an air space. The viewing windows are bonded together by a filled water glass-based adhesive (20) which surrounds the visual region in a circumferential manner.

Description

Die Erfindung betrifft ein Isolierglaselement für die zumindest teilweise Begrenzung eines Brennraumes mit wenigstens zwei Sichtscheiben bestehend aus zumindest bereichsweise transparentem Glas- oder Glaskeramikmaterial, die unter Belassung eines Luftraumes zueinander beabstandet angeordnet sind, und wobei im Bereich des Luftraums zumindest teilweise ein Sichtbereich gebildet ist.The invention relates to an insulating glass element for the at least partially delimiting a combustion chamber with at least two viewing panes consisting of at least partially transparent glass or glass ceramic material, which are spaced apart leaving an air space, and wherein in the region of the air space at least partially a viewing area is formed.

Solche Isolierglaselemente kommen bei Raumheizern, beispielsweise Kaminöfen oder sonstigen Brennanlagen (beispielsweise Müllverbrennungsanlagen, Pyrolyseöfen, Krematorien ...) oder auch bei Backöfen beispielsweise als Backofentür zum Einsatz. Sie ermöglichen dem Anwender den Einblick in den Brennraum. Dabei wird durch den Mehrscheibenaufbau eine Isolationswirkung erzielt.Such insulating glass elements are used in room heaters, such as stoves or other firing systems (for example, waste incinerators, pyrolysis ovens, crematoria ...) or in ovens, for example as a door oven. They allow the user insight into the combustion chamber. In this case, an insulating effect is achieved by the multi-disc structure.

Aus der GB 1, 087, 296 ist eine Tür für einen Ofen bekannt. Diese weist zwei zueinander parallele Sichtscheiben auf, die mittels Distanzstücken auf Abstand gehalten werden. In dem so gebildeten Luftraum kann Raumluft zirkulieren. Diese erwärmt sich beim Durchtritt durch den Luftraum und hilft bei der Raumbeheizung.From the GB 1, 087, 296 is a door known for a stove. This has two mutually parallel viewing panes, which are held by spacers at a distance. Room air can circulate in the airspace thus formed. This heats up as it passes through the air space and helps with space heating.

In der US 40 58 107 ist ein Türsystem beschrieben, welches ebenfalls aus zwei mit Abstandhalteeinrichtungen versehenen Sichtscheiben besteht. Der Türrahmen beinhaltet eine Reihe von Luftdurchlassöffnungen sowohl in der unteren als auch oberen Halteleiste, damit die im Scheibenzwischenraum erhitzte Luft konvektieren und dem Aufstellraum warme Luft zuführen kann.In the US 40 58 107 a door system is described, which also consists of two provided with distance maintaining devices lenses. The door frame incorporates a series of air vents in both the lower and upper support rails so that the air heated in the space between the panes can convect and supply warm air to the installation room.

Die US 2004 00 11 348 A1 beschreibt einen Doppelscheibenaufbau, der ebenfalls einen Zwischenraum zwischen beiden Sichtscheiben definiert. Die Sichtscheiben sind jedoch nicht parallel zueinander angeordnet, sondern so aufgebaut, dass sich der Spalt am oberen Ende der Sichtscheiben verringert. Zusätzlich sorgt ein Gebläse dafür, dass entweder Raum- oder Frischluft in den Scheibenzwischenraum geblasen wird, um insbesondere die innere Sichtscheibe zu kühlen. Ziel ist es, eine Temperaturbelastung zu erreichen, bei welcher sicher vorgespanntes Kalk-Natron-Glas eingesetzt werden kann.The US 2004 00 11 348 A1 describes a double disc structure, which also defines a gap between the two lenses. However, the lenses are not arranged parallel to each other, but so constructed that the gap at the upper end of the lenses is reduced. In addition, a fan ensures that either room or fresh air is blown into the space between the panes, in particular to cool the inner visor. The aim is to achieve a temperature load, in which safely biased soda-lime glass can be used.

Das US-Patent 2005/01 39 209 A1 geht schließlich noch einen Schritt weiter. Wie in US 2004 00 11 348 beschrieben, konvektiert entweder Luft ohne Zwang oder aber mit Unterstützung eines Gebläses zwischen zwei Scheiben. Die äußere Sichtscheibe ist durch eine Plastikscheibe ersetzt. Zum Betrieb des Gebläses ist elektrische Energie nötig, die die Energiebilanz verschlechtert.The US Patent 2005/01 39 209 A1 finally goes one step further. As in US 2004 00 11 348 described, convected either air without force or with the assistance of a blower between two discs. The outer lens is replaced by a plastic disc. For the operation of the fan electrical energy is needed, which worsens the energy balance.

Bei den bekannten Isolierglaselementen sammelt sich Staub und je nach Konstruktion Ruß im Luftraum zwischen den Sichtscheiben, so dass eine regelmäßige Reinigung erforderlich ist. Eine der Sichtscheiben müsste daher jeweils ausbaubar in einer Halterung integriert sein. Dies ist bei den bekannten Systemen nicht mit geringem Aufwand möglich. Darüber hinaus bedingt dies eine aufwändige Rahmenkonstruktion für das Isolierglaselement. Weiterhin hat sich gezeigt, dass die Sichtscheiben bei Verpuffungen im Brennraum hohen Belastungen ausgesetzt sind. Die bei einer Verpuffung entstehenden Kräfte werden über die Distanzstücke von der inneren auf die äußere Sichtscheibe übertragen. Dabei entstehen im Bereich der Distanzstücke lokale Druckspitzen. Um diese sicher abtragen zu können, müssen die einzelnen Sichtscheiben eine ausreichende Festigkeit und damit eine ausreichende Dicke aufweisen.In the known insulating glass elements dust collects and, depending on the construction soot in the air space between the lenses, so that a regular cleaning is required. One of the lenses would therefore be removable each integrated in a holder. This is not possible with little effort in the known systems. In addition, this requires a complex frame construction for the insulating glass element. Furthermore, it has been shown that the viewing windows are exposed to high loads during deflagrations in the combustion chamber. The resulting in a deflagration forces are on the spacers from the inner to the Transfer outer lens. This creates local pressure peaks in the area of the spacers. In order to remove these safely, the individual lenses must have sufficient strength and thus a sufficient thickness.

Bei den bekannten Isolierglaselementen ist weiterhin auch eine nachteilige Auswirkung auf das Emissionsverhalten der Brennstelle zu beobachten. Die der Brennstelle zugekehrte Sichtscheibe wird durch die im Luftraum zirkulierende Luft gekühlt. An der Innenseite der gekühlten Innenscheibe wird die Entstehung von zum Beispiel Stickoxiden begünstigt, die zu einer Verschlechterung des Abgasverhaltens beitragen. Durch die Kühlung der Innenscheibe wird zudem die Verbrennungstemperatur begrenzt, was zu einer erhöhten Feinstaubemission führt.In the known insulating glass elements is also an adverse effect on the emission behavior of the burner can be observed. The viewing window facing the combustion chamber is cooled by the air circulating in the air space. On the inside of the cooled inner pane, the formation of, for example, nitrogen oxides is promoted, which contribute to a deterioration of the exhaust gas behavior. By cooling the inner pane, the combustion temperature is also limited, resulting in increased particulate matter emission.

Es ist Aufgabe der Erfindung, ein Isolierglaselement der eingangs erwähnten Art zu schaffen, das zu einem verbesserten Emissionsverhalten der Brennstelle beiträgt und dabei einfach reinigbar ist.It is an object of the invention to provide an insulating glass element of the type mentioned, which contributes to an improved emission behavior of the combustion and is easy to clean.

Diese Aufgabe wird dadurch gelöst, dass die beiden Sichtscheiben mittels eines temperaturbeständigen Klebers miteinander verbunden sind, und dass der Kleber umlaufend einen Sichtbereich der Sichtscheiben umschließt, oder dass ein zumindest teilweise umlaufender Abstandshalter mit den beiden Sichtscheiben stoffschlüssig verbunden, vorzugsweise verklebt ist.This object is achieved in that the two viewing panes are connected to each other by means of a temperature-resistant adhesive, and that the adhesive circumferentially surrounds a viewing area of the viewing panes, or that an at least partially circumferential spacer materially connected to the two viewing windows, preferably glued.

Gegenstand der Erfindung ist somit die dauerhafte Verbindung von zwei oder mehreren Sichtscheiben mittels einer Verklebung zu einem festen Scheibenverbund. Damit kann das Isolierglaselement als eine Baueinheit gehandhabt und ähnlich einfach wie eine Einzelscheibe verbaut werden. Dabei gestaltet sich die Abdichtung des Isolierglaselementes in einem umgebenden Rahmen, beispielsweise einem Türrahmen, deutlich einfacher. Insbesondere kann auf die sonst erforderlichen Dichtlagen zwischen den Einzelscheiben verzichtet werden. Dies erweitert die Gestaltungsmöglichkeiten für den Türrahmen. Insbesondere kann dieser nun mit geringerer Bautiefe ausgeführt werden. Dadurch, dass der Rahmen nun mit geringerer Baugröße ausgeführt werden kann, entsteht auch eine Materialeinsparung und eine Gewichtsreduzierung.The invention thus relates to the permanent connection of two or more viewing panes by means of a bond to a solid disc composite. Thus, the insulating glass element can be handled as a unit and built as simple as a single disc. In this case, the sealing of the insulating glass element in a surrounding frame, such as a door frame, much easier. In particular, can be dispensed with the otherwise required sealing layers between the individual panes. This extends the design options for the door frame. In particular, this can now with less depth be executed. The fact that the frame can now be carried out with a smaller size, also results in a material saving and a weight reduction.

Das Isolierglaselement bildet aufgrund der Verklebung ein Bauteil mit hoher Steifigkeit, so dass es selbst auch das tragende Element einer Tür bilden kann. Auf einen Rahmen kann dann gegebenenfalls verzichtet werden, wobei die Scharniere und Verschlusselemente unmittelbar mit dem Isolierglaselement verbunden werden oder es wird ein Rahmen verwendet, der die Verbindung mit den Scharnieren und den Verschlusselementen vermittelt. Darüber hinaus können auch Sichtscheiben mit geringerer Dicke eingesetzt werden, was zu einer weiteren Gewichts- und Materialeinsparung bei ausreichender Stabilität führt.Due to the bonding, the insulating glass element forms a component with high rigidity, so that it can itself also form the load-bearing element of a door. On a frame can then optionally be dispensed with, wherein the hinges and closure elements are directly connected to the insulating glass element or it is used a frame that provides the connection with the hinges and the closure elements. In addition, lenses with a smaller thickness can be used, resulting in further weight and material savings with sufficient stability.

Dadurch, dass der Kleber umlaufend den Sichtbereich umschließt, wird ein staubdichter Abschluss gebildet, so dass der Luftraum dauerhaft sauber bleibt. Somit kann eine regelmäßige Reinigung entfallen.Due to the fact that the adhesive surrounds the viewing area all the way around, a dust-tight closure is formed, so that the air space remains permanently clean. Thus, a regular cleaning can be omitted.

Weiterhin begrenzt der Kleber im Luftraum ein isolierendes Luftvolumen. Damit wird das Emissionsverhalten positiv beeinflusst, da nun höhere Verbrennungstemperaturen im Brennraum entstehen.Furthermore, the adhesive in the air space limits an insulating air volume. This has a positive influence on the emission behavior, since now higher combustion temperatures are created in the combustion chamber.

Gegenstand der Erfindung ist, alternativ die Verbindung der beiden Sichtscheiben unter Zuhilfenahme eines Abstandshalters, der im Bereich zwischen den Sichtscheiben angeordnet ist und mit diesem verklebt werden kann. Der Abstandshalter (und die Klebeschichten) schaffen wieder einen staub- und rußdichten Abschluss des Luftraums. Der Abstandshalter verbessert auch die Lastübertragung zwischen den Teilscheiben und steift darüber hinaus diese aus.The invention is alternatively, the connection of the two lenses with the aid of a spacer which is arranged in the region between the lenses and can be glued to this. The spacer (and the adhesive layers) again create a dust and soot-tight closure of the air space. The spacer also improves the load transfer between the part discs and also stiffens them out.

Gemäß einer bevorzugten Ausgestaltungsvariante der Erfindung kann es vorgesehen sein, dass die Sichtscheiben mittels eines gefüllten, wasserglasbasierten Klebers miteinander verklebt sind. Dieser Kleber ist auch bei hohen thermischen Belastungen ausreichend temperaturbeständig. Der Kleber kann beispielsweise mit niedrig dehnenden Füllstoffen wie Quarzmehl, gefüllt sein, was zu einer Verringerung der thermischen Ausdehnung führt. Dies ist insbesondere bei Verwendung von Null-Ausdehnungsglaskeramiken als Scheibenmaterial von Bedeutung, um Rissbildung zu vermeiden und langfristig die Temperaturwechselbeständigkeit zu gewährleisten.According to a preferred embodiment variant of the invention, it can be provided that the viewing windows are glued together by means of a filled, water glass-based adhesive. This adhesive is sufficiently temperature resistant even at high thermal loads. The glue can be used, for example low-expansion fillers such as quartz flour, filled, resulting in a reduction in thermal expansion. This is particularly important when using zero-expansion glass ceramics as disc material in order to prevent cracking and to ensure long-term thermal shock resistance.

Wenn vorgesehen ist, dass der ausgehärtete Kleber gasdurchlässig ist, dann ist ein Druckausgleich zwischen dem Luftraum und der Umgebung bei Temperaturwechseln möglich. Die staubdichte Abtrennung des Luftraumes bleibt erhalten. Die Gasdurchlässigkeit kann durch ein entsprechend poröses Klebermaterial eingestellt werden. Denkbar ist es auch, ein Druckausgleichelement, beispielsweise einen poröser Keramikfilter, in die Klebeschicht oder in den Abstandshalter zu integrieren beziehungsweise dem Abstandshalter zuzuordnen. Das Druckausgleichelement sollte eine staubdichte Abgrenzung bilden.If it is provided that the cured adhesive gas permeable, then a pressure equalization between the air space and the environment during temperature changes is possible. The dust-tight separation of the air space is retained. The gas permeability can be adjusted by a correspondingly porous adhesive material. It is also conceivable to integrate a pressure compensation element, for example a porous ceramic filter, into the adhesive layer or into the spacer or allocate it to the spacer. The pressure compensation element should form a dustproof boundary.

Ist es nach einer Ausgestaltungsvariante der Erfindung vorgesehen, dass der ausgehärtete Kleber hydrophob ist, dann kann das Eindringen von Wasser (als Verbrennungsprodukt oder Luftfeuchte) in den Luftraum vermindert oder vollständig unterdrückt werden.If it is provided according to an embodiment variant of the invention that the cured adhesive is hydrophobic, then the penetration of water (as a combustion product or air humidity) can be reduced or completely suppressed in the airspace.

Eine deutliche Materialoptimierung bei ausreichender Festigkeit kann bei einem Isolierglaselement dadurch erreicht werden, dass die Sichtscheiben eine unterschiedliche Dicke aufweisen. Die dicker Sichtscheibe erfüllt statische Anforderungen, die durch die dünnere Sichtscheibe materialsparend ergänzt werden und um das Isolierglaselement zu komplettieren. Besonders bevorzugt sind insbesondere für die dünnere Sichtscheibe Dicken kleiner oder gleich 4mm mit dieser Konstruktion verwirklichbar. Für bestimmte Formatgrößen können auch Isolierglaselemente aufgebaut werden, bei denen beide Sichtscheiben gleiche Dicken, insbesondere kleiner gleich 4 mm aufweisen.A significant material optimization with sufficient strength can be achieved in an insulating glass element in that the lenses have a different thickness. The thick visor fulfills static requirements, which are supplemented by the thinner lens to save material and to complete the insulating glass element. Particularly preferred thicknesses less than or equal to 4mm can be realized with this construction, especially for the thinner lens. For certain format sizes and insulating glass elements can be constructed in which both lenses have the same thickness, in particular less than or equal to 4 mm.

Eine denkbare Erfindungsausgestaltung ist derart, dass zwischen zwei äußeren Sichtscheiben eine oder mehrere innere Sichtscheiben angeordnet sind, und dass die inneren Sichtscheiben eine deutlich geringere Dicke als die beiden äußeren Sichtscheiben aufweisen.One conceivable embodiment of the invention is such that one or more inner viewing panes are arranged between two outer viewing panes, and that the inner viewing panes have a significantly smaller thickness than the two outer viewing panes.

Die beiden äußeren Scheiben eines solchen Isolierglaselementes bringen eine ausreichende Stabilität. Die innere/inneren Scheibe(n) müssen keine oder nur geringe mechanische Belastungen ableiten und erhöhen deutlich die Isolationswirkung.The two outer panes of such insulating glass element bring sufficient stability. The inner / inner disc (s) must dissipate no or only small mechanical loads and significantly increase the insulation effect.

Die Erfindung wird im Folgenden anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles erläutert.The invention will be explained below with reference to an embodiment shown in the drawings.

In der Fig. 1 ist ein Isolierglaselement 10 mit zwei zueinander parallel beabstandeten Sichtscheiben 11, 12 gezeigt. Zwischen den beiden Sichtscheiben ist ein Luftraum gebildet. Die Sichtscheiben 11, 12 können beispielsweise aus einer durchsichtigen Glaskeramik bestehen. Zur Verbindung der beiden Sichtscheiben 11, 12 wird ein Kleber 20 verwendet, der in Form einer Kleberaupe am Rand 13 der Sichtscheiben 11, 12 umlaufend angeordnet ist. Die Kleberaupe umschließt den Sichtbereich der Sichtscheiben 11, 12, durch den hindurch ein Einblick auf eine Feuerstelle eines Ofens ermöglicht ist. Der Kleber 20 verklebt die beiden Sichtscheiben 11, 12 umlaufend, so dass der Luftraum staubdicht gegenüber der Umgebung abgeschlossen ist. Die umlaufende Kleberaupe ermöglicht auch eine gleichmäßige Lastübertragung von der einen in die andere Sichtscheibe 11, 12.In the Fig. 1 is an insulating glass element 10 with two mutually parallel spaced lenses 11, 12 is shown. Between the two lenses an airspace is formed. The lenses 11, 12 may for example consist of a transparent glass ceramic. To connect the two lenses 11, 12, an adhesive 20 is used, which is arranged circumferentially in the form of a bead of adhesive on the edge 13 of the lenses 11, 12. The adhesive bead surrounds the field of view of the viewing panes 11, 12, through which an insight into a hearth of a furnace is made possible. The adhesive 20 glues the two viewing panes 11, 12 circumferentially, so that the air space is sealed dust-tight with respect to the environment. The circumferential adhesive bead also allows a uniform load transfer from one to the other lens 11, 12th

Das Isolierglaselement 10 gemäß Fig. 1 kann mit einem Türrahmen 30 zu einer Ofentür komplettiert werden. Der Türrahmen 30 besteht aus vier Rahmenprofilen 31, 32, die zu einem geschlossenen Rahmen verbunden sind. Dabei weisen die Rahmenprofile 31, 32 einen Deckabschnitt auf, mit dem die Kleberaupe des Isolierglaselementes 10 außenseitig abgedeckt ist, so dass sich eine optisch ansprechende Gestaltung ergibt.The insulating glass element 10 according to Fig. 1 can be completed with a door frame 30 to an oven door. The door frame 30 consists of four frame profiles 31, 32, which are connected to form a closed frame. In this case, the frame profiles 31, 32 on a cover portion with which the bead of adhesive of the insulating glass element 10 is covered on the outside, so that there is a visually appealing design.

Die vertikalen Rahmenprofile 32 tragen auf der Scharnierseite zwei Scharnierteile 34 und auf der Anschlagseite einen Verschluss 33, beispielsweise einen Griff mit einer Schließzunge.The vertical frame profiles 32 carry on the hinge side two hinge parts 34 and on the stop side a closure 33, for example, a handle with a locking tongue.

Zur Verbindung der beiden Sichtscheiben 11, 12 kann alternativ zu der Kleberaupe auch ein Abstandshalter verwendet werden, der in Form eines umlaufenden Rahmens zwischen den zueinander parallelen Sichtscheiben 11, 12 angeordnet ist. Der Abstandshalter besitzt auf gegenüberliegender Seiten ebene Auflageflächen, auf denen die Sichtscheiben 11, 12 mit ihren einander zugewandten Seiten unter Zwischenlage einer Klebeschicht aufgesetzt sind. Die Klebeschicht verbindet die Sichtscheiben 11, 12 derart stoffschlüssig, dass von dem Abstandshalter und den Sichtscheiben 11, 12 ein Luftraum begrenzt ist. Um zu verhindern, dass bei Temperaturwechselphasen Druckunterschiede zwischen der Umgebung und dem Luftraum entstehen, ist dem Abstandshalter ein Druckausgleichselement zugeordnet. Dieses schafft einen Druckausgleich zwischen der Umgebung und dem Luftraum. Das Druckausgleichelement kann in den Abstandshalter integriert sein oder dessen umlaufende Form streckenweise unterbrechen. Das Druckausgleichelement wird von einem Filter, beispielsweise einer porösen Keramik, gebildet.To connect the two viewing panes 11, 12, a spacer can be used as an alternative to the adhesive bead, which is arranged in the form of a circumferential frame between the mutually parallel viewing panes 11, 12. The spacer has on opposite sides planar bearing surfaces on which the lenses 11, 12 are placed with their sides facing each other with the interposition of an adhesive layer. The adhesive layer connects the viewing panes 11, 12 in such a material-locking manner that an air space is bounded by the spacer and the viewing panes 11, 12. In order to prevent pressure differences between the environment and the air space during temperature change phases, the spacer is assigned a pressure compensation element. This creates a pressure balance between the environment and the airspace. The pressure compensation element may be integrated in the spacer or interrupt its circumferential shape in parts. The pressure compensation element is formed by a filter, for example a porous ceramic.
