Definitions
- the invention relates to a viewing window for a closed from the environment hot space, designed as a multi-pane module with at least two spaced by transparent spacers, which are gas-tightly connected to the spacers.
- Hot rooms which are closed from the surroundings and have high operating temperatures typically have a viewing window in order to allow a view into the hot room from the outside.
- the viewing window can be permanently installed in the wall delimiting the hot room.
- the viewing window can also be integrated in a door of the wall delimiting the hot room in a typical form of application.
- Typical examples are oven doors, such as oven doors, especially those with pyrolytic self-cleaning or microwave ovens.
- Viewing windows can also be provided in fire protection doors that close off a room that only becomes a hot room in the event of a fire.
- Viewing windows for the aforementioned purposes are typically designed as a multi-pane module, with at least two glass panes spaced apart by spacers in a composite frame.
- the known viewing window has a window assembly with two glass panes arranged in a composite frame, which form a glass pane assembly, this window assembly being arranged in the door with a free air gap to the front glass pane, with which it forms the multi-pane module.
- the glass pane assembly is formed in a vapor-tight manner by a circumferential seal which is also effective under the influence of heat, in particular a glass silk seal, in order to prevent vapors or vapors from the oven muffle from getting into the space between the two glass panes of the window assembly and contaminating the panes.
- a circumferential flow barrier is provided in the free space between the front pane and the window assembly.
- the disks separated by the spacer are hermetically sealed together with the spacer by means of a temperature-resistant adhesive, in particular a silicone adhesive.
- the glass pane exposed to the interior temperature of the device typically consists of THERMAX 5000 ® , a tempered, heat-reflective coated soda-lime float glass, and the glass pane exposed to the ambient temperature and, if necessary, another inner one
- the intermediate disc is made of DURAX ® , a toughened soda-lime float glass.
- the distance between the glass panes depends on the temperature, which places special design requirements on the construction for the mechanical holding of the glass panes, the composite frame. Furthermore, the spacer is constantly exposed to deformation, which does not have a favorable effect on material fatigue.
- a viewing window for fire protection glazing with a multi-pane module has become known, in which the panes are held at a distance by a sealing compound and are connected to one another in a sealing manner.
- This multi-disc module has a very complex pressure compensation system with valves that open in the event of a fire and release the gas pressure that builds up as a result of the temperature increase before it causes the discs to burst.
- Such a multi-pane module can also only be provided with a metallic frame at great expense in terms of production technology, and it has become known from DE 39 15 687 C 2 to provide this module with an edge surround made of a flexible, gas-permeable band.
- an evacuated insulating glass consisting of two panes with intermediate spacers, for example cylindrical spacers, which are distributed according to a specific grid.
- the edges of the glass panes are hermetically sealed by either glass solder or metal solder to prevent air from entering.
- the distance between the disks is approx. 100 ⁇ m.
- This multi-pane module has a number of disadvantages. For example, the use of thermally or chemically toughened glass is not possible, since the soldering temperatures are typically above the relaxation temperature of the toughened glass. Thermally toughened glasses also show deviations in flatness, which make the extremely small distances no longer possible. Relaxed glasses must either have a thickness of min.
- the invention is based on the object of designing the viewing window for a hot space sealed off from the surroundings, designed as a multi-pane module with at least two transparent panes which are spaced apart by circumferential spacers and which are gas-tightly connected to the spacers, in such a way that despite the gas-tight ones Connection between the spacers and the disks a pressure equalization between the space between the disks and the environment without contamination of the disks is possible with simple means.
- At least one opening is formed in the spacers, which is closed with a permeable filter which allows gases to pass through to equalize the pressure, but prevents the entry of vapors and vapors. If an increased pressure builds up in the space between the panes due to an increase in temperature, air can escape from the interior through the filter. If the space between the panes cools down again, filtered ambient air flows into the space. Any vapors and vapors that are deposited in the filter are filtered out.
- the filter is therefore expediently designed to be exchangeable.
- the filter is preferably designed as a filter cartridge.
- the panes are preferably made from a glass with high thermal resistance, for example a thermally or chemically toughened borosilicate glass.
- the panes consist of a glass ceramic which is highly temperature-resistant.
- the spacers preferably consist of stainless steel or aluminum or a sufficiently temperature-resistant plastic.
- the spacers are glued to the panes according to an embodiment of the invention using a temperature-resistant adhesive, preferably a silicone adhesive.
- the viewing window according to the invention is expediently designed such that at least one of the panes is provided with a heat radiation-reflecting layer on at least one side.
- Fig. 1 in a schematic perspective front view
- Embodiment of a multi-disc module with filters in the disc spacers Embodiment of a multi-disc module with filters in the disc spacers
- FIG. 2 shows a cross-sectional view of the module according to FIG. 1.
- FIGS. 1 and 2 of the multi-pane module according to the invention of a viewing window for a hot room closed off from the surroundings has two transparent panes 1 and 2 which are held in a frame (not shown).
- the panes 1 and 2 consist 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 held at a predetermined distance all around by spacers 3.
- the spacers are typically made of stainless steel, aluminum or a sufficiently temperature-resistant plastic.
- the spacers 3 are bonded to the glass or glass ceramic panes 1 and 2 using a temperature-stable adhesive, typically a silicone adhesive, to form a composite, which is indicated in FIG. 2 by the adhesive seam 4.
- the spacers 3 also have bores 5 on at least one side of the module, according to FIG. 1 on the upper side and according to FIG. 2 also on the lateral spacer. These holes 5 are filled with a filter material 6, which on the one hand brakes the gas exchange rate, but prevents a build-up of pressure in the space between the two disks 1, 2 and on the other hand also prevents the penetration of vapors in the form of greases, oils and other dirt particles that prevent the space between the disks could pollute.
- a filter material 6 which on the one hand brakes the gas exchange rate, but prevents a build-up of pressure in the space between the two disks 1, 2 and on the other hand also prevents the penetration of vapors in the form of greases, oils and other dirt particles that prevent the space between the disks could pollute
- 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 symbolically represented in FIG. 2 by the position 7, the layers facing one another in the case of panes coated on one side. Disks coated on both sides can also be used.
- the essential heat transfer mechanisms radiation (through an IR reflection layer), convection (through the reduced gas exchange) and conduction (through the use of poor heat conductors such as glass, ceramic, wood, plastics) can be switched off in a simple manner, the disadvantages being known Systems do not come into play.
- the filter 6 is preferably designed as a filter cartridge in order to enable the filter to be replaced. Therefore, the openings in the spacers, which are closed by a filter, are preferably formed in the area of the spacers that is easy to grip.
- the multi-pane module according to the invention is used in connection with a spaced-apart front pane, preferably as a door assembly for an oven door, the free space between the module and The windshield is advantageously ventilated in order to keep the temperature of the windshield as low as possible, even during the phase of pyrolytic self-cleaning.
