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, in particular for ovens or ovens or drying cupboards with an arrangement of glass, glass-ceramic or another transparent, temperature-resistant pane held by a common frame Material.
  • Viewing windows of this type are generally known. They are usually arranged in the front doors of ovens or the like. The following description is for household ovens. However, the invention can also be used for any other device which has a viewing window or door which separates an interior space deviating from its ambient temperature and through which 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.
  • a transparent heat protection element for frying ovens, heating chambers and the like is known, with at least two glass panes arranged in parallel and an all-round edge connector which connects the glass panes to one another and at a predetermined distance holds, the edge connector has a spacer profile that is only placed between the edges of the pane, and each glass pane is glued to one another and to this spacer profile by means of a sealing compound that remains elastic even under the influence of heat.
  • DE-GM 77 06 648 is based on the task of specifying a heat protection element in which the thermal insulation is improved and the inside fogging and soiling is prevented.
  • DE 36 02 455 A1 discloses an oven for baking, roasting, grilling and the like.
  • a cooking space with at least one heating element provided in particular on its top and a door closing the cooking space from two spaced-apart parallel door shells, of which in particular each has a glass pane the two door shells, for example, via profile rails arranged between them with two spaced-apart parallel legs U or Z profile strips or the like.
  • the outer legs are glued to the outer door shell.
  • DE 36 02 455 A1 is based on the object of designing an oven in such a way that the outer door shell does not have any areas that collect the dirt and excessive heating of the outer door shell is avoided.
  • thermochromic panes on the inside, the radiation permeability of which is reduced when the temperature rises. However, this affects the view through the window.
  • panes of a multi-pane arrangement with a coating which either reflects infrared radiation or reduces the emission of infrared radiation.
  • a coating which has both of these properties is, for example, one made of fluorine-doped tin dioxide. If it is attached to the inside of a pane facing the temperature-increased room, it reflects some of the infrared radiation back into the interior, if it is attached to the outside of a pane, it reduces the infrared radiation to the outside towards the next outer pane.
  • the panes can also be coated on both sides.
  • DE 42 06 820 A1 shows an oven door for an oven with a see-through window, the at least one glass pane of which has a coating reflecting heat rays, the reflective coating being applied to the surface of the glass panes facing away from the interior of the oven.
  • the object of this invention is also to bring about a lowering of the temperature on the front of the oven.
  • each panel was previously attached individually by the stove manufacturer when the viewing panels were installed. This is associated with a high expenditure of material and time.
  • the object of the invention is therefore to propose measures with which a further increase in the temperature difference between the interior temperature during operation of the respective device, for example in household ovens or refrigerators and freezers, and its ambient temperature is possible. These measures are also intended to reduce energy consumption.
  • a further disk is arranged between the window exposed to the ambient temperature and the interior temperature of the device.
  • All disks can be arranged parallel to one another or at least two disks form an acute angle between 0.5 ° and 10 ° with one another.
  • the disks enclosing the angle of inclination are preferably arranged in such a way that the inclination of the disks relative to one another extends in a vertical direction. Depending on the application, the disks can converge upwards as well as diverge upwards.
  • the temperature-reducing effect of the inclination is presumably due to certain radiation patterns, and possibly also through improved convection
  • the panes of the viewing window can have different material compositions.
  • 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 further disc is connected at the edge to the disc, which is exposed to the ambient temperature.
  • the distance between the intermediate, further pane, from the pane which is exposed to the ambient temperature is determined by means of spacers, in particular between 5 mm and 20 mm.
  • the spacers are made of materials that have a thermal insulation effect, in particular ceramic, glass, plastic or silicone.
  • the spacers are compressible and designed as a silicone tube.
  • This compressible, compressible silicone hose easily enables the necessary pressure equalization when the oven is heated.
  • the compressible volume of the silicone tube is adapted to the different temperature differences and air volumes that occur between the panes.
  • a temperature-resistant adhesive in particular a silicone adhesive, is used according to the invention.
  • silicone adhesive also simplifies the recycling of the used and discarded window composite, since only the two materials glass and silicone are obtained.
  • a gas-tight gluing of the spacers to the intermediate pane and the pane exposed to the ambient temperature creates a closed space and thus an insulating viewing window.
  • the gas-tight space between the panes can be filled with a poorly heat-conducting gas, e.g. Argon, krypton or carbon dioxide.
  • a poorly heat-conducting gas e.g. Argon, krypton or carbon dioxide.
  • the gas-tightly sealed space must have options for pressure compensation in the event of temperature changes. This is possible using simple, known measures.
  • panes can also be advantageous to provide at least one of the panes on one or both sides with a heat-reflecting layer, in particular with tin dioxide.
  • the intermediate pane of the temperature-insulating viewing window is the same size or larger than the pane exposed to the interior temperature of the device and smaller than the pane exposed to the ambient temperature.
  • At least one further pane is arranged by means of adhesive between the further pane located therebetween and the pane exposed to the interior temperature of the device.
  • the viewing window is available pre-assembled as a ready-to-install unit for mounting in a device with an interior temperature that differs from the ambient temperature.
  • the oven door is made up of three viewing panels (inner, middle panel and front panel). The distance between the inner pane and the outer pane is 22 mm.
  • the pane size of the inner and middle pane is approximately 400 x 300 mm2.
  • 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.
  • the front window surface temperature of 65 ° C results when the middle viewing window is attached to the door panel.
  • the assembly described in Fig. 1 results in a windscreen surface temperature of 60 ° C.
  • a commercial household oven is used for this example, which is additionally equipped with the option of pyrolytic self-cleaning.
  • the oven door has four windows (inner window, two middle windows and a front window).
  • the inner and middle pane have the size of approx. 300 x 400 mm.
  • the inner pane and the middle pane closest to the baking chamber are provided with a heat-reflecting layer on the side facing the other pane.
  • the second middle pane from the baking chamber and the front pane are made of DURAX.
  • the front window is a curved window.
  • the disks are mounted as shown in Fig.2.
  • the two middle panes are attached to the curved front pane with a tubular circumferential spacer using temperature-resistant silicone adhesive.
  • the entire disc package has a thickness of approx. 50 mm.
  • the windscreen surface temperature of 63 ° C results with conventional mounting of the inner and middle panes on the door panel.
  • the windscreen surface temperature is 45 ° C.
