Definitions
- the invention relates to a temperature-insulating viewing window or door for a device with an interior temperature that deviates from its ambient temperature, especially for cooking or baking ovens or drying cabinets with one held by a common frame arrangement of spaced Glass, glass-ceramic or another transparent pane temperature-resistant material, being between the, the ambient temperature and the pane exposed to the interior temperature of the device at least a further disc is arranged, which is edge with one of the outer panes is connected by means of gas-tight glued spacers.
- the invention can also be used for any other device that a Viewing window or door, which one of its ambient temperature different interior separates and through that an insight into this Space is possible, e.g. also for freezers and refrigerators, or Drying cabinets.
- the inner window and any additional windows and the front window are attached to the door panel. Since the door panel is in direct contact with the baking chamber and is made of a good heat-conducting material (metal), the viewing panels are heated, among other things, by heat conduction.
- the outer pane with its inside no longer borders directly on the temperature-increased room, so that already heating of the outer pane through direct heat transfer avoided becomes. Nevertheless, even with several spaced-apart panes with an air gap heating of the outer pane by radiation from the temperature-increased Interior, this radiation partly the inner Glasses happens and directly from the outer pane, but sometimes also from the inner panes is absorbed, which in turn then emits heat again send out to the next outer disc or the next outer one Disc over the air-filled space through heat conduction and convection Warm up.
- This thermal protection element already improves thermal insulation and prevents it fogging and dirtying of the panes on the inside.
- thermochromic panes on the inside, whose radiation permeability is reduced when the temperature rises. However, this affects the view through the window.
- one or more of the disks of a multi-disk arrangement to be coated with either infrared radiation reflected or reduced the emission of infrared radiation.
- a this coating having both properties is, for example, one those made of fluorine-doped tin dioxide.
- the panes can also be double-sided be coated.
- a temperature-insulating viewing window or a temperature-insulating door for an oven with an arrangement of glass panes positioned at a distance and held by a common frame can be derived, in which between the ambient temperature and the interior temperature of the Device exposed disc is arranged at least one further disc, which is connected at the edge to the outer disc, which faces the interior of the device, by means of gas-tight glued spacers.
- This oven window also lowers the temperature on the front of the oven.
- German published patent application DE 23 10 084 A1 discloses a heat-insulating Shielding that can form part of an oven or cooker being made from at least one plate of glass or an in vitro crystalline Material consists of which at least a part has been chemically hardened is.
- the German patent application DE 25 45 531 A1 shows an oven door with a viewing window made up of a composite of parallel to each other and spaced apart inner glass panes and from one There is outer pane, being between the inner glass panes and the called outer pane a convection space open to the outside Thermal insulation for heat dissipation and in the edge area of the panes is provided, in particular for baking and roasting tubes with pyrolytic Self-cleaning, and being the distance between the glass panes of the inner bond is several times smaller than the distance between the outermost glass pane of the composite of the outer pane.
- the object of the present invention is a temperature-insulated viewing window propose its thermal insulation effectiveness for the whole Lifetime can be easily maintained.
- the spacer is designed as a compressible hose, the volume of the compressible Hose enables pressure equalization in the event of temperature changes.
- the panes of the viewing window can have different material compositions exhibit.
- the disc exposed to the interior temperature of the device consists, for. B. typically made of THERMAX 5000 R , a tempered, heat-reflective coated soda-lime float glass, the intermediate pane and the pane exposed to ambient temperature made of DURAX R , a tempered soda-lime float glass.
- the intermediate disc is marginal with connected to the disc, which is exposed to the ambient temperature.
- the distance between the intermediate, further disc from the Washer exposed to the ambient temperature especially between 5 mm and 20 mm.
- they are more compressible Hose-made silicone spacers.
- a temperature-resistant adhesive in particular a silicone adhesive is used.
- the use of the silicone adhesive also simplifies the recycling of the used one and the window pane assembly to be disposed of, since only the two Materials glass and silicone are incurred.
- the gas-tight space between the panes can also be sealed with a poorly heat-conducting gas, e.g. Argon, krypton or carbon dioxide filled be.
- a poorly heat-conducting gas e.g. Argon, krypton or carbon dioxide filled be.
- the intermediate disc is the temperature insulating Viewing window larger than that of the interior temperature of the Device exposed disc.
- the viewing window is pre-assembled as a ready-to-install Unit for mounting in a device with a different temperature Indoor temperature available.
- a standard household oven is used.
- the oven door is made up of three windows (inner, middle pane and front pane) built up.
- the distance between the inner pane and the outer pane is 22 mm.
- the pane size of the inner and middle pane is approx. 400 x 300 mm 2 .
- the inner pane is made of THERMAX 5000 R , a toughened, heat-reflecting coated soda-lime float glass. The heat-reflecting layer of this pane is arranged facing away from the baking chamber.
- the middle pane and the front pane are made of DURAX R , a toughened soda-lime float glass.
- the middle and inner disc are arranged according to Fig.1.
- the middle pane is attached to the front pane with a tubular circumferential spacer using a temperature-resistant silicone adhesive.
- a commercial household oven is used for this example, which is additionally equipped with the option of pyrolytic self-cleaning is.
- the oven door has four panes (inner pane, two middle panes) Windows and a front window). Have the inner and middle pane the size of approx. 300 x 400 mm.
- the inside and from the baking room The next middle pane is facing the other pane Side with a heat reflective layer.
- the ones from The baking chamber consists of a second middle pane and the front pane are made of DURAX.
- the front window is a curved window.
- the discs are as shown in Fig.2 assembled.
- the two middle discs are with a tubular, all-round spacers with the help of temperature-resistant silicone adhesive attached to the curved windscreen.
- the entire disc package has a thickness of approx. 50 mm.

Description
Da das Türblech in direktem Kontakt zu dem Backraum steht und aus einem gut wärmeleitenden Material (Metall) gefertigt ist, werden die Sichtscheiben u.a. über Wärmeleitung erwärmt.
Außerdem wird bisher bei der Montage der Sichtscheiben durch den Herd-Hersteller jede Scheibe einzeln befestigt. Dies ist mit hohem Material- und Zeitaufwand verbunden.
