Definitions

  • the invention relates to an insulating glass unit for a refrigerated cabinet, a door for a refrigerated cabinet, a method for producing such an insulating glass unit and their use.
  • Refrigerated shelves or refrigerators with transparent doors are widely used to display and present refrigerated goods to customers.
  • the goods are kept at temperatures below 10 ° C in the refrigerator and thus protected against rapid deterioration.
  • insulating glass units are often used as doors.
  • Transparent doors allow you to view the goods without having to open the cabinets or shelves.
  • Each opening of the doors leads to an increase in the temperature in the cooling rack and thus exposes the goods to the risk of heating. It is therefore desirable to present the goods so that the number of opening operations is minimized. For this it is important that the view through the closed doors is restricted as little as possible.
  • the view is obstructed, at least in the edge region, by elements of the non-transparent surrounding door frame.
  • the door frame conceals in conventional insulating glass units also the non-transparent circumferential edge seal.
  • the edge bond of an insulating glass unit usually comprises at least one circumferential spacer, moisture-binding desiccant and a primary sealing means for fixing the spacer between the discs and a secondary sealant which stabilizes the edge seal and additionally seals.
  • These components are usually not transparent, that is in the area of the peripheral edge compound, visibility is limited.
  • a refrigerator which comprises two insulating glass units as doors, which contain a transparent spacer element on at least one vertical side and on this side no frame element.
  • the spacer element is designed as a T-shaped cross-sectional profile, which simultaneously fulfills a supporting and a sealing function.
  • the spacer element is designed as a one-piece, solid profile, which is produced by extrusion.
  • Another approach is described in WO2014 / 198549 A1.
  • transparent spacer elements are used, which are arranged between the discs at least on one vertical side.
  • the transparent spacer elements are fixed in particular with adhesive strips between the panes.
  • spacers made of transparent plastic resins that can be used in combination with metallic spacers along the horizontal sides.
  • the combination of such different materials is problematic in insulating glass units. Different coefficients of expansion of the materials used can permanently lead to leaks in the edge bond.
  • the sealants must be matched to the materials of the spacers. When using several types of sealants, it can easily lead to material incompatibilities between the sealants, which in turn trigger leaks in the edge seal.
  • a spacer for a multi-pane insulating glazing is known, the at least one composite of a glass fiber reinforced polymer base body, two parallel disc contact surfaces, a bonding surface and a
  • Glazing interior space and an insulating film comprises.
  • the disc contact surfaces and the bonding surface are connected directly or via connecting surfaces.
  • the main body preferably has a glass fiber content of 20% to 50%, particularly preferably from 30% to 40%.
  • the glass fiber content in the base body simultaneously improves the strength and stability, however, the production of transparent spacers or spacers with colored patterns is disturbed due to the presence of the reinforcing fibers.
  • a glazed element comprising an insulating glazing.
  • the insulating glazing contains at least a first and a second glass pane, which are connected by means of a spacer.
  • the spacer is formed by a transparent resin consisting of polymethylmethacrylate, polycarbonate, polystyrene, polyvinylchloride, acrylonitrile-butadiene- Styrene, nylon or a mixture of these compounds is selected.
  • Such a spacer has the advantage that it opposes the possible exchange of gas, moisture and dust between the surrounding areas and the gas filling of the glazing and at the same time being transparent, whereby it is possible to see through him the products contained in the refrigerated container furniture without the consumer's view being obstructed by the presence of a frame or, in particular, side struts.
  • the spacers are generally a hollow, extruded or shaped profile of metal or organic material or also a profile with connecting angles or a corner folded profile. A reference to said polymers is not produced.
  • the object of the present invention is to provide an improved insulating glass unit for a refrigerated cabinet, to provide a door for a refrigerator, and also to provide a simplified method for manufacturing an insulating glass unit. Specifically, it was the object of the present invention to provide an insulating glass unit for a refrigerated cabinet, which on the one hand has a particularly high stability and pressure resistance of the spacers and on the other hand duplicates the design possibilities of the spacers.
  • the insulating glass unit according to the invention for a refrigerated cabinet comprises at least a first pane, a second pane spaced therefrom, and a peripheral spacer frame between the first pane and the second pane.
  • An inner disc space is limited by the spacer frame, the first disc and the second disc.
  • the inner pane space is enclosed by the spacer frame.
  • the insulating glass unit has four sides. The sides of the insulating glass unit are the sides along which the edge area of the insulating glass unit is located. The two first sides are opposite each other and the two second sides are opposite each other.
  • the spacer frame comprises at least four polymeric hollow profile spacers. Each polymeric hollow profile spacer is attached along one of the four sides of the insulating glass unit.
  • the polymeric hollow profile spacers are each along the four sides between attached to the first disc and the second disc via a primary sealant.
  • Two first polymeric hollow profile spacers are disposed along the two opposite first sides and two second polymeric hollow profile spacers are disposed along the two second sides of the insulating glass unit.
  • the first polymeric hollow profile spacers contain 5% to 50% reinforcing fibers. The reinforcing fibers lead to increased stability of the polymeric hollow profile spacers and thus to a longer life of the insulating glass unit.
  • the polymeric hollow profile spacers advantageously have low thermal conductivities compared to metallic hollow profile spacers.
  • the second polymeric hollow profile spacers contain 0% to 0.5% reinforcing fibers, which makes the design options are particularly diverse. For example, the fact that no or nearly no reinforcing fibers are included makes it possible to produce transparent spacers or spacers with colored patterns that would otherwise be disturbed by the presence of the reinforcing fibers. Due to the lack of reinforcement, the second polymeric hollow profile spacers have a lower compressive strength. Surprisingly, however, the insulating glass unit according to the invention with first and second polymeric hollow profile spacers has excellent stability. The arrangement according to the invention along opposite sides of the insulating glass unit results in a highly stable insulating glass unit which is comparable to insulating glass units which have reinforced spacers along all four sides.
  • the insulating glass unit according to the invention has the advantage that the edge bond has a lower thermal conductivity.
  • the invention provides a stable insulating glass unit having a polymeric spacer profile along all four sides and thus having excellent heat insulating properties.
  • the second polymeric hollow profile spacers are made transparent. This has the advantage that there is no visual barrier along two opposite sides so that the viewing area is maximized. Because the second polymers Hollow profile spacers according to the invention contain virtually no reinforcing fibers, they can be made transparent translucent. In conventional insulating glass units are provided for polymeric hollow profile spacers generally around reinforcing fibers. Therefore, no insulating glass units are used with transparent hollow profile spacers so far. The insulating glass unit according to the invention is surprisingly stable even without the stabilizing effect of the reinforcing fibers along all four sides, so that the transparent embodiment becomes possible.
  • Transparent in the sense of the invention means that the material is transparent. An observer can recognize the objects arranged behind the material layer.
  • the material is thus translucent and preferably has a light transmission in the visible spectrum of at least 30%, more preferably of at least 50%.
  • Reinforcing fibers in the sense of the invention refer to fibers which are added to reinforce the profile of the polymeric body of the hollow profile. These fibers are preferably glass fibers, natural fibers or ceramic fibers. These fibers increase the stiffness and strength of the profile.
  • the fibers are preferably used in the form of short fibers with lengths between 0.05 mm and 0.5 mm. These lengths can be processed particularly well in an extruder, so that the reinforcing fibers can be incorporated directly in the extrusion. The percentages are percent by mass of reinforcing fibers based on the proportion of reinforcing fibers on the polymeric base body, that is, any barrier films or coatings are not taken into account.
  • the polymeric hollow profile spacers comprise at least one polymeric main body at least comprising a first side wall, a second side wall arranged parallel thereto, a glazing interior wall, an outer wall and a cavity.
  • the cavity is enclosed by the side walls, the glazing interior wall and the exterior wall.
  • the glazing interior wall is arranged perpendicular to the side walls and connects the first side wall with the second side wall.
  • the side walls are the walls of the polymeric hollow profile spacer to which the outer panes of the insulating glass unit are attached.
  • the first side wall and the second side wall run parallel to each other.
  • the glazing interior wall is the wall of the polymeric hollow profile spacer, which faces the inner space between the panes in the finished insulating glass unit.
  • the outer wall is arranged substantially parallel to the glazing interior wall and connects the first side wall to the second side wall.
  • the outer wall faces the outer space between the panes.
  • the cavity of the polymeric body leads to a weight reduction compared to a solid shaped spacer and may be completely or partially filled with a desiccant.
  • At least one of the first two polymeric hollow profile spacers contains a desiccant and the cavity of the two second polymeric hollow profile spacers is free of desiccant.
  • the desiccant binds moisture, which is present in the inner space between the panes, thus preventing fogging of the insulating glass unit from the inside.
  • the second polymeric hollow profile spacers need not be filled with desiccant because attachment in at least one of the hollow profile spacers is sufficient to prevent fogging of the discs. So on the one hand material can be saved and on the other hand this procedure also has optical advantages.
  • the desiccant preferably contains silica gels, molecular sieves, CaCl 2 , Na 2 SO 4 , activated carbon, silicates, bentonites, zeolites and / or mixtures thereof.
