Definitions

  • the invention relates to a glazed door for a device with a raised or lowered Indoor temperature, with one held by a common frame Arrangement of glass, glass ceramic or glass panes positioned at a distance another transparent temperature-resistant material, with between exposed to the ambient temperature and the indoor temperature Washer a spacer is arranged with which at least one further disk can be connected at the edge.
  • the invention also relates to the device having the glazed door with elevated or reduced indoor temperature.
  • Viewing doors of this type are known; they are usually on the front Openings of ovens or refrigerators and the like are arranged.
  • the following description is given for each device that has a glazed door separates a temperature-increased interior from the outside environment and through which the outside view of this room is increased or decreased Temperature is enabled.
  • 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.
  • One of these two Coating having properties is one such fluorine-doped tin dioxide. If it faces the temperature-increased room Attached to the inside of a pane, it reflects part of the Infrared radiation back into the interior, it becomes on the outside of one Attached pane, it reduces the infrared radiation to the outside next outer disc.
  • the panes can also be coated on both sides his.
  • German patent application DE 42 06 820 A 1 is an oven door for an oven with a see-through window, at least its a glass pane has a coating reflecting heat rays, the reflective coating facing away from the interior of the oven Surface of the glass panes is applied.
  • German Laid-open specification DE 42 06 820 A 1 is also a temperature-insulating one Viewing window or a temperature-insulating door for an oven with a spaced from a common frame arrangement positioned glass panes in which the ambient temperature and exposed to the interior temperature of the device Disc is arranged at least one other disc, which is on the edge the outer pane, which faces the interior of the device, by means of gas-tight glued spacer is connected.
  • This oven window causes also a lowering of the temperature on the front of the oven.
  • the interior temperature special fastening measures are provided.
  • German patent DE 43 33 033 C1 is a temperature-insulating Viewing door of the type described is known, in which the also rotating Spacers are designed as a compressible tube, the volume of the compressible hose to equalize the pressure when the temperature changes allows.
  • Both double-pane and multi-pane devices are available on the market. mostly three-pane glazed doors. Attaching one or more Windows in addition to the window exposed to the interior temperature and the windscreen exposed to the ambient temperature in the known oven doors a clear deviation from the manufacturing process a double pane door, because a change in the Construction of the frame is necessary, with additional parts, for example metallic holder with seals and screw connections, for fixing the additional washer is required, or is along with the attachment gastight circumferential composite frames very expensive.
  • DE 198 35 217 A1 discloses a glazed door for a device with an increased interior temperature, especially known for a household oven, with one of a common frame held arrangement of spaced apart Clear panes of glass, glass ceramic or another transparent temperature resistant material, being between the ambient temperature and a spacer for the pane exposed to the interior temperature is arranged, with which at least one further disk is connected at the edge can be, the spacer from a poorly heat-conducting Material only with one of the outer panes using a temperature resistant Adhesive is connected and that it as a profile with at least one longitudinal groove is formed to accommodate another disc suitable is.
  • To provide interior temperature that is sufficient is heat insulating or temperature insulating, which is clear and when in use remains transparent and can be produced with little material and time is.
  • the task is through a glazed door for a device with elevated or reduced indoor temperature, with one of a common frame held arrangement of spaced glass panes, Glass ceramic or another transparent temperature-resistant material, being between that of the ambient temperature and that of the interior temperature exposed disc a spacer is arranged with the at least one further disk can be connected at the edge, the spacer from a poorly heat-conducting material with only one of the outer ones Disks is connected by means of a temperature-resistant adhesive and that it is designed as a profile with at least one longitudinal groove, which is suitable for receiving another disc, between the spacers a cavity between the outer and the next pane having.
  • the cavity in the spacer according to the invention has a spring effect.
  • This spring action in the form of a membrane creates a tight seal between the outer disc and the spacer. It will be surprising prevents contamination and liquids like hot grease penetrate into the gap and stick to the inside of the put down the first disc.
  • the glazed door consists of a frame and one held by this frame Arrangement of glass, glass-ceramic panes positioned at a distance or some other transparent temperature-resistant material.
  • the individual panes can also be made of different materials consist.
  • the disks can be coated in the usual way.
  • a spacer according to the invention from a poorly heat-conducting Material that is only heat-resistant to one of the two discs
  • Adhesive in particular a silicone adhesive, is connected and the is designed as a profile with at least one longitudinal groove for receiving another disc is suitable.
  • Arrangements are often used to reduce the outside temperature of the glazed door used with more than two discs.
  • one or more others Simply insert the panes precisely or using a thermal insulation Material to be embedded.
  • the spacer consists of a poorly heat-conducting and sufficient temperature-resistant material, for example made of suitable silicones, Wood or wood composite materials or from temperature-stable organic Polymers.
  • the spacer is preferably designed as a U-shaped circumferential profile or is formed by sections of a profile, which are below themselves at the corners are connected by inserted elbows, so that the u-shaped revolving profile results that is open to the upper door wheel.
  • the spacer does not have to be continuous. He can also be formed from separate profile sections, of which at least in each case one on the left, right and bottom of the outer Washer is attached.
  • the profile sections must be chosen at least so large that one inserted window is sufficiently fixed.
  • the arrangement of the disc (s) held by the spacer is that the spacer is only glued to one of the two outer disks and not contacted one, also in such a way that it contacts an outer Disk is not connected at all and with the other only about the bad thermally conductive spacers. This decoupling of the middle disc (s) the thermal insulation of the door is improved.
  • the spacer can with one outer disc on its edge surface be glued. When connected to the window facing the interior he can also have an additional groove in which this disc is glued is.
  • the two outer panes can be attached to the frame in different ways Wise can be realized.
  • the pane facing the interior is preferred with the frame glued, for example via an adhesive bead, but can also, for example screwed to him. If the pane facing the interior in a groove of the spacer is connected to this, the gluing between the frame and the pane facing the interior be that the spacer is also adhesively connected to the frame is. However, the spacer preferably has no contact with the frame.
  • the front screen is preferably attached to the outside of the frame of the viewing door. This is for example by means of an adhesive, by means of mounting brackets or by means of Brackets or clamps possible.
  • the format is the windscreen preferably chosen so large that it, especially on the sides, with the the outer edge of the frame is flush.
  • the face of the edge of the The windscreen is edge-processed, preferably with a so-called C-cut Mistake.
