    专利说明:

    [001] The invention relates to a refrigerator, especially a commercial refrigerator for storing food.
    [002] A refrigerator is currently understood to be a refrigerated cabinet, which has a refrigeration unit or is connected to a separate refrigeration unit. The refrigerator maintains the cooling space at temperatures below the ambient temperature around the refrigerator. Refrigerators also include freezers, in which they are stored at a temperature of, for example, -18°C and even lower. The refrigerator has a vertically oriented cooling chamber, in which a plurality of superimposed shelves are arranged.
    [003] The refrigerator has an access opening in a vertical plane, which can be closed by at least one hinged or displaceable door. The refrigerator door features a multiple glazing, which comprises at least two transparent panes of glass spaced apart from each other. The distance between the two panes of glass is adjusted by spacers arranged on the edge side between the panes of glass. In addition, the two glass panes of a refrigerator door are framed by structural elements that support the glass panels and where the refrigerator door is suspended.
    [004] Both spacers and structural elements are generally made of metal profiles, which form a non-transparent door frame for the surrounding glass panels. This door frame restricts the view from the outside to the refrigerator and/or the food on the shelves.
    [005] The invention is therefore based on providing a refrigerator with a better view from the outside to your refrigerator.
    [006] According to the invention, a vertical spacer made from a transparent material is provided on at least one transparent vertical edge of the refrigerator door, and no structural element is provided on the transparent vertical edge, which comprises on the edge side the glass panels. In the case of an access opening, in which two or more refrigerator doors are arranged, the transparent vertical edge of the refrigerator door of the vertical edge of the refrigerator door which is located in the center of the access opening, i.e. the vertical edge may have a greater effect. Since no structural element is provided on the transparent vertical edge, the transparency of the transparent-vertical edge is considerably improved.
    [007] The transparent vertical spacer links the two glass panes together and keeps the glass panes at a set distance. In addition, the transparent spacer seals the gap between the two parallel glass panels, so that the gas in the gap between the glass panels does not leak out and moisture from the air does not enter. The transparent vertical spacer has less of a supporting function and more of a sealing function. With this arrangement, maximum transparency of the glass panel unit is achieved from all viewing angles.
    [008] Preferably, the transparent vertical spacer is made of silicone, PMMA, polycarbonate or other transparent thermoplastic. The transparent spacer preferably has a certain elasticity to ensure as flat and uniform placement as possible of the transparent spacer on the glass panel over a long period of time and under shock loads.
    [009] Thermoplastics are plastic materials that can be deformed with a certain range of temperatures. Preferably, polycarbonate is used in the production of the vertical spacer. Polycarbonate has very good heat insulating properties and remains transparent and color stable over a long period of time.
    [010] Preferably, the lip seal between the transparent spacer on the one hand and the two glass panels on the other hand has a firm bond. The spacer and the glass panels are particularly preferably bonded together by an adhesive. This adhesive forms a mechanical bond and a gas-tight seal. The adhesive is preferably of an acrylic base, as such adhesives have good long-term properties with respect to their transparency, integrity and adhesion.
    [011] The gap between the panels existing between the glass panels is preferably gas-tight and essentially serves as insulation. In the gap between the glass panels there is preferably a thermal insulating gas. The insulating gas is preferably argon noble gas. Since argon has a relatively large molecular size, argon gas does not diffuse (or only very slowly) through the transparent spacer and/or adhesive.
    [012] Preferably, a separate sealing strip is provided distal to the transparent spacer, which consists of a sealing compound. The sealing compound is adjacent to the spacer and closes, on the edge side, the gap between the two panes of glass. This may therefore be useful and necessary because the spacer-adhesive is essentially designed for a strong mechanical connection of the spacer to the glass panels, but not necessarily as a sufficiently gas-tight barrier. The sealing strip, however, must not have a high holding force for a reliable mechanical connection between the two panes of glass, but rather serve, in the first line, a sufficiently strong gas seal of the gap between the panes of glass.
    [013] The sealing compound is preferably transparent. The sealing compound can be formed similarly to the spacer-adhesive. Alternatively, the sealing compound is not identical to the spacer-adhesive and is preferably made of butyl rubber.
    [014] According to a preferred embodiment, the refrigerator door, on its upper and lower horizontal edge, has separate structural elements, which engage and comprise the front sides of the glass panels. The structural elements are not transparent, and are made of metal. There may also be spacers arranged on the structural elements made of non-transparent material, which does not correspond to the material of the transparent spacer.
    [015] In particular, since the lower horizontal edge and the upper edge of a refrigerator door do not disturb or only slightly disturb the view in the refrigerator, they can be applied, on both horizontal edges of the refrigerator door, namely support elements with high strength, which, for example, are made of metal profiles. The stability and cohesion of the entire refrigerator door is ensured through stable structural elements on both horizontal edges of the refrigerator door. In a particularly preferred way, the second vertical side of the refrigerator door, which is opposite the transparent vertical side, is arranged on the edge of the access opening, in the case of closing the door, it can be equipped with a separate structural element and a non-transparent spacers, which can, for example, be made of metal profiles.
    [016] Preferably, the spacer has an adhesive groove that is filled with the spacer-adhesive. The adhesive bonds, in the adhesive groove, the glass panel and spacer in a firm and substantially gas-tight bond. The adhesive groove can have a round, oval, domed or diamond-shaped cross section. The adhesive groove extends substantially in the longitudinal direction of the transparent spacer, i.e. vertically along the entire length of the spacer. Alternatively or additionally, grooves may also be provided to accommodate the sealing elements, sealing lips, etc.
    [017] Preferably, the glass panels consist of an anti-reflective glass, preferably a laminated safety glass. The coating causes low light reflection and good transparency and translucency. However, not both glass panels have an expensive anti-reflective coating. Preferably, at least one glass panel has an anti-reflective coating. Mainly, the glass panel on the outside has an anti-reflective coating on the inside.
    [018] Preferably, an impact protection strip is provided on the transparent vertical edge, which completely covers the front surface of the two glass panels. The impact protection strip preferably has an overall width, which results from at least the sum of the two panel forces and their distance, so that the impact protection strip completely covers the front surfaces of the glass panes and preferably is bonded to the outer sides of the two panes of glass. The impact protection strip has, substantially, the function of protecting the front surfaces of the two glass panels on the transparent vertical edge against mechanical damage.
    [019] The impact protection strip preferably has a rectangular shape, but can have a convex curvature on the front side of the glass panel. With this curvature of the impact protection strip, side impacts can be better absorbed and damage to the glass panels can be avoided.
    [020] According to a preferred embodiment, the transparent spacer is integrally formed by an impact protection strip and forms, together with this, a T-shaped profile. With the one-piece spacer design, together with the shock protection strip, the escape path 5 is considerably increased, resulting in an improved sealing of the gap of the glass panels against the leakage of gas from the gap of the glass panels. In addition, it has a poor appearance of edges. Finally, the parallel glass panels are supported by the T-shaped profile in the cross section, even during assembly in a defined position. As the shock protection strip represents a stop for the front surfaces of the glass panels. The T-shaped profile can be configured, for example, as an extrusion profile.
    [021] Two examples of embodiment of the invention follow, explained in more detail with reference to the drawings. In the drawings:
    [022] Figure 1 is a perspective view of a refrigerator with two refrigerator doors,
    [023] Figure 2 shows a cross-section of a first embodiment of the transparent vertical edge of a refrigerator door of the refrigerator of Figure 1,
    [024] Figure 3 shows a cross-section of the lower horizontal edge of the refrigerator door of Figure 1, and
    [025] Figure 4 shows a cross-section of a second embodiment of the transparent vertical edge of a refrigerator door of the refrigerator of Figure 1.
    [026] In Figure 1, a refrigerator 10 is shown, whose refrigeration space 14 is cooled at temperatures above 0°C, for example, at +5°C. Basically, however, the invention can also relate to a refrigerator 10, whose refrigeration space 14 is cooled to temperatures below 0°C, for example to -18°C.
    [027] The refrigerator 10 comprises a refrigerator body 12, which surrounds the refrigeration space 14. In the refrigeration space 14, a plurality of shelves are arranged, accessible from the front side 18, in which food 20 can be stored. . The body of the refrigerator 12 has, on the front side, an access opening 16 arranged in the vertical plane and with a large surface, through which access to food 20 is possible. In the access opening 16 there is a set of doors 11, which substantially has two refrigerator doors 32, 32'. The set of doors 11 has been adapted to the refrigerator 10, that is, assembled according to the configuration of the refrigerator 10 in the access opening 16. Of course, the set of doors 11 can also be provided by the factory in the refrigerator 10.
    [028] The access opening 16 is closed by two refrigerator doors 32, 32' transparent and in the vertical plane, when the refrigerator doors 32, 32' are in their closed position. Refrigerator doors 32.32' are peripherally fixed with pivoting joints around a vertical rotation axis on the body of refrigerator 12.
    [029] The two refrigerator doors 32, 32' are double-glazed and therefore each has two transparent glass panels 54, 55, with a handle 22 attached to the outer glass panel 54. The two clear glass panels 54, 55 of a refrigerator door 32, 32' are surrounded by an upper horizontal structural element 58, a lower horizontal structural element 59 and a pivotable vertical structural element 56.
    [030] Each refrigerator door 32, 32' features a glass panel 55 on the inside and a glass panel 54 on the outside. The two panes of glass 54, 55 are spaced apart by spacers 56', 57', 59' disposed on the edge side. Between the spaced glass panels 54, 55 is the gap between the panels. This gap between the panels 62 is filled with an insulating argon gas 82. The glass panel 54 on the outside has an anti-reflective and heat-reflective coating on the inside.
    [031] Figure 2 shows a cross-section of a first embodiment of the transparent vertical edge of a refrigerator door 132' of the refrigerator 10 of Figure 1. The refrigerator door 132' does not have, on the side that is in the center of the access opening 16, no structural element, which comprises the glass panels 54,55 and/or hangs from the refrigerator door 132' directly or indirectly. The assembly provided on the transparent vertical rim 150 is essentially a hermetic seal of the gap 62 between the two glass panels 54, 55. The assembly 150 is particularly non-directly connected to the structural elements 56, 58, 59, which comprise the others. three sides of glass panels 54, 55,
    [032] The transparent spacer 157' is provided between the two glass panels 54, 55 along the entire length of the transparent side edge. The clear spacer 157' is made of silicone, but it can also be made of PMMA or a polycarbonate. The clear spacer 157' is elastic within certain limits so that it conforms closely to the surfaces of the adjacent glass panels 54, 55. The clear spacer 157' is not arranged indirectly on the edge of the glass panels, but is offset by some millimeters inside. The clear spacer 157' is bonded with an adhesive 50 to the acrylic base on both sides with the glass panels 54,55. The transparent spacer 157' has, in its longitudinal direction, which extends spatially in the vertical direction, in two panes of glass 54, 55, an adhesive groove 166 for receiving the adhesive 50. The spacer 157' serves substantially as a spacer. exact of the two panes of glass 54, 55.
    [033] Distally adjacent to the spacer 157' is associated a sealing strip 110 consisting of a sealing compound 112. The sealing compound 112 is made of butyl rubber, but may also be made of another suitable transparent material, preferably transparent. The sealing strip 110 is mainly used for gas-tight sealing of the gap between the glass panels 62, so that the leakage of insulating gas 82 on the one hand and the ingress of air and moisture on the other hand also be minimized and/or excluded for several decades. The sealing strip 110 is approximately flush with the side surfaces 74 of the two glass panels 54, 55.
    [034] The transparent vertical edge of the refrigerator door 132' features, as a closure, a plastic shock protection strip 172, which completely covers the two front surfaces 74 and the sealing strip 110 and, in particular, the mechanical protection of the glass panels 54, 55 against damage. The front side 80 of the crash protection strip 172 is formed in a slightly convex shape.
    [035] In Figure 3, the lower horizontal edge of the refrigerator door 32'; 132' is shown in cross-section, which is structurally and substantially distinguished from the transparent vertical edge of the same refrigerator door 32'; 132'. As spacer 59', a hollow metal profile 60 is provided, which has a plurality of small openings for the clearance of the glass panels 62. The hollow spacer 59' is filled with a drying agent 61, which serves to absorb moisture from the gap 62. In addition to the spacer 59' is a sealing strip 52 made of butyl rubber, or any other suitable drying agent. seal. The sealing strip 52 is approximately aligned with the edges of the two glass panels 54, 55. Furthermore, a structural element 59 is provided, which is designed with a U-shaped metal profile 63, which completely covers the two panes of 54.55 glass. The metal profile of the structural member 63 is approximately aligned with the edges of the two glass panels 54,55.
    [036] The upper horizontal lip and the vertical lip on the hinged side 32, 32' can be constructed in the same way as that shown in Figure 3 with respect to the lower horizontal lip of the refrigerator door 32'. The three structural elements 56, 58, 59 are mechanically connected, for example screwed and/or glued together. The three structural elements 56, 58, 59 are fixed with swivel joints, directly or indirectly, to the body of the refrigerator 12.
    [037] Figure 4 shows a cross-section with a transparent vertical edge according to a second example embodiment of the right refrigerator door 32' of the refrigerator 10. The spacer 57' is here a part of an integral profile body , T-shaped and in cross section, which is composed of a central bar 78 and a cross bar. The central bar 78 has a rectangular shape. The central bar 78 extends between the two parallelly opposite glass panels 54, 55. The central bar 78 has, on the two horizontal arms on the longitudinal side, a groove of adhesive 66 in a round, oval or diamond shape. Into this adhesive slot 66, a suitable liquid adhesive is inserted in the manufacture of the refrigerator door 32, 32'. The crossbar forms a crash protection strip 72 and is located on the front side surfaces 74 of the two glass panels 54, 55. The length of the crossbar is in a ratio of about 2:3 to the length of the center bar 78 of the T-shaped profile body. The glass panel side of the shock protection strip 72 has a domed and convex front surface 80.
