Definitions

  • the invention relates to a viewing window for one from the environment closed hot room, designed as a multi-pane module with at least two spaced by circumferential spacers transparent panes that are gas-tightly connected to the spacers.
  • Hot rooms typically have a viewing window around one To allow a view into the hot room from the outside.
  • the viewing window can, depending after application, permanently installed in the wall defining the hot room his.
  • the viewing window can also be used for a typical application be integrated in a door of the wall delimiting the hot room.
  • Typical examples of this are stove doors, such as oven doors, especially those with pyrolytic self-cleaning or Microwave ovens.
  • Viewing windows can also be provided in fire doors that enclose a room complete, which only becomes a hot room in the event of a fire.
  • Viewing windows for the aforementioned purposes are typically as Multi-disc module designed with at least two spacers in glass panes held spaced apart by a composite frame.
  • the well-known window has one Window assembly with two arranged in a composite frame Glass panes that form a glass pane composite, these Window assembly with a free air gap to the front glass pane, with this forming the multi-pane module is arranged in the door.
  • the Glass pane bond is by a circumferential, also under the influence of heat effective seal, in particular a glass fiber seal in itself vapor-tight trained to prevent vapors or vapors from the oven muffle get into the space between the two glass panes of the window assembly and can contaminate the windows.
  • the glass pane exposed to the interior temperature of the device exists typically made of THERMAX 5000®, a prestressed heat-reflective coated soda-lime float glass, and that of Glass pane exposed to ambient temperature and possibly another inner one
  • the intermediate pane is made of DURAX®, a toughened soda-lime float glass.
  • the distance between the Glass panes depend on the temperature, which leads to the construction for the mechanical holding of the glass panes, the composite frame, special constructive requirements are made. Furthermore, the spacer constantly exposed to deformation, which is not favorable in terms of Material fatigue.
  • DE 36 37 064 C 2 is a viewing window for fire protection glazing become known with a multi-disc module, in which the discs held at a distance by a sealing compound and sealing on the other be connected to each other.
  • This multi-disc module has a very elaborate pressure compensation system with valves, which are in the event of fire open and the gas pressure building up due to the temperature increase drain before the discs burst.
  • Such a Multi-pane module can also only with a large one production-technical effort provided with a metallic frame be, it has become known from DE 39 15 687 C 2, this Module with a border made of a flexible, gas-permeable tape to provide.
  • the edges of the glass panes are hermetically sealed by either glass solder or metal solder to the To prevent air entry.
  • the distance between the disks is approx. 100 ⁇ m.
  • DE-C-19 802 688 is the basis for the preamble of claim 1.
  • This multi-disc module has a number of disadvantages. That's how it is Not possible to use thermally or chemically toughened glass, since the soldering temperatures are typically above the relaxation temperature of the toughened glass. Thermally toughened glasses also have Flatness deviations on the extremely short distances no longer make possible. Relaxed glasses must either have a thickness of min. 6 mm to withstand the vacuum, making the module extreme becomes heavy, or the spacer grid is made very dense, so that it is difficult to see through. When using special solders for low When using soldering temperatures, there is a risk that the seal will break. In addition, it can be expected that the panes are under temperature load bend while touching each other; the interruption of heat conduction would no longer exist.
  • the invention is based on the object of the type mentioned Viewing window for a hot room isolated from the surroundings, designed as a multi-disc module with at least two rotating ones Spacers spaced transparent discs that are gas-tight with the spacers are connected, so designed that despite the gas-tight Connection between the spacers and the washers Pressure equalization between the space between the discs and the Environment without the windows getting dirty, with simple Funds is possible.
  • the filter is therefore expedient designed to be interchangeable.
  • the filter is preferably a filter cartridge educated.
  • the disks are preferably made of a glass with high thermal resistance, for example one thermally or chemically toughened borosilicate glass.
  • the disks consist of a Glass ceramic that is highly temperature-resistant.
  • the spacers consist according to an advantageous embodiment of the Invention preferably made of stainless steel, or aluminum or a sufficient temperature resistant plastic.
  • the spacers are according to one Embodiment of the invention using a temperature-resistant Adhesive, preferably a silicone adhesive, glued to the panes.
  • the viewing window according to the invention is expedient trained that at least one of the disks on at least one side with is provided with a layer reflecting heat radiation.
  • Multi-pane module according to the invention of a viewing window for one of the Enclosed hot room has two transparent panes 1 and 2, which are held in a frame, not shown.
  • Panes 1 and 2 are made of glass with high thermal resistance, typically from a chemically or thermally toughened borosilicate flat glass, or from a transparent glass ceramic.
  • Both disks are encircled by spacers 3 on one kept predetermined distance.
  • the spacers typically exist made of stainless steel, aluminum or a sufficiently temperature-resistant Plastic.
  • the spacers 3 are made using a temperature-stable adhesive, typically a silicone adhesive with the glass or glass-ceramic panes 1 and 2 glued into a composite, which is shown in FIG. 2 by the adhesive seam 4 is indicated.
  • a temperature-stable adhesive typically a silicone adhesive with the glass or glass-ceramic panes 1 and 2 glued into a composite, which is shown in FIG. 2 by the adhesive seam 4 is indicated.
  • the spacers 3 also have at least one side of the module Bores 5, according to FIG. 1 on the upper side and according to FIG. 2 also the side spacer. These holes 5 are with a Filter material 6 filled, which on the one hand slows down the gas exchange rate, but a pressure build-up in the space between the two disks 1, 2 prevents and on the other hand also the penetration of vapors in the form of Greases, oils and other dirt particles that prevent the Can contaminate the space between the panes.
  • the multi-disc module "breathes" through the filter unit, so to speak.
  • the panes 1, 2 are preferably coated in a heat-reflecting manner, which is indicated in Fig. 2 is symbolically represented by position 7, with one-sided coated panes facing each other. It can too discs coated on both sides are used.
  • the essential can be easily Heat transfer mechanisms: radiation (through an IR reflection layer), Convection (due to reduced gas exchange) and Conduction (by using poor heat conductors such as glass, ceramic, wood, Plastics) switch off, the disadvantages of known systems not being Come wear.
  • the filter 6 is preferably designed as a filter cartridge to a To allow interchangeability of the filter. Therefore the openings are in the spacers, which are closed by a filter, preferably in handle-friendly area of the spacers.
  • the multi-pane module according to the invention is used in conjunction with a spaced front pane, preferably as a door assembly
  • Front screen is advantageously ventilated to the temperature of the front screen to keep as low as possible, even during the phase of a pyrolytic Self-cleaning.
