Definitions

  • 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.
  • 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.
  • a door system 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.
  • 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.
  • 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.
  • the viewing window facing the combustion chamber is cooled by the air circulating in the air space.
  • the formation of, for example, nitrogen oxides is promoted, which contribute to a deterioration of the exhaust gas behavior.
  • the combustion temperature is also limited, resulting in increased particulate matter emission.
  • 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.
  • the invention thus relates to the permanent connection of two or more viewing panes by means of a bond to a solid disc composite.
  • the insulating glass element can be handled as a unit and built as simple as a single disc.
  • the sealing of the insulating glass element in a surrounding frame, such as a door frame much easier.
  • This extends the design options for the door frame. In particular, this can now with less depth be executed.
  • the insulating glass element forms a component with high rigidity, so that it can itself also form the load-bearing element of a door.
  • 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.
  • lenses with a smaller thickness can be used, resulting in further weight and material savings with sufficient stability.
  • 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.
  • 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.
  • 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.
  • the cured adhesive gas permeable 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • profile sections are connected to an at least partially encircling frame together, preferably glued.
  • the profile sections can consist of the same material as the lenses 11, 12.
