Definitions

  • the invention relates to a heat insulation housing for a refrigeration appliance, in particular household refrigeration appliance, according to the preamble of patent claim 1 and a vacuum insulation panel for such a heat insulation housing according to claim 10.
  • a vacuum insulation panel can be introduced before the foaming process in the still empty wall space. Its inherent rigidity is usually insufficient to withstand the foaming process without changing the shape and position. For this reason, the vacuum insulation panel may be supported via holding elements on the inner wall or the outer wall of the housing body.
  • such a heat insulation housing in whose device body a vacuum insulation panel is used. This is positioned in the correct position with the help of spacers.
  • the spacers may be formed on the inner wall or the outer wall of the housing body.
  • the spacers are provided in large numbers distributed over the entire side wall surface.
  • they are mounting technology consuming mounted on the inner wall and / or the outer wall, for example by screwing or gluing.
  • the spacers can also be formed directly as bulges in the inner wall or the outer wall.
  • the vacuum insulation panel is stressed by the filled, not yet cured politiciansisolierschaum with deformation forces.
  • the deformation forces can lead to distortions in the vacuum insulation panel.
  • Position and / or shape change of the vacuum insulation panel can thus lead directly to an adverse curvature or buckling of the outer wall and / or the inner wall.
  • the object of the invention is to provide a heat insulating housing in which the vacuum insulation panel is arranged in a simple manner dimensionally stable and in the correct position in the wall space.
  • the invention relates to a heat insulation housing with a, a cooling space bounding inner wall, an outer wall and a wall space, which is filled with a heat insulating material and in which a vacuum insulation panel is arranged.
  • the outer wall merges at opposite edges of the housing into angled edge strips, which are connected to the inner wall and / or with other adjacent outer wall parts, such as floor, ceiling or rear wall.
  • the invention is based on the fact that the spacers known from the prior art provide a force path during the foaming process. Deformation forces can be introduced into the outer wall during the foaming process by bridging the free gap between the vacuum insulation panel and the outer wall via this force path, as a result of which it can deform disadvantageously.
  • the characterizing part of claim 1 is completely dispensed with such spacers between Vakuumisolationspaneel and the outer wall / inner wall, whereby a free gap is maintained. Rather, the vacuum insulation panel is attached force-transmitting to the angled edge strips of the outer wall / inner wall. Preferably, the vacuum insulation panel can be supported with the interposition of an additional retaining element on the edge strips of the outer wall.
  • the heat insulation housing can be used in a refrigeration device.
  • a refrigeration appliance is understood in particular to be a household refrigeration appliance, that is to say a refrigeration appliance used for household purposes or possibly even in the gastronomy sector, and in particular for storing food and / or beverages in household quantities at specific temperatures, such as, for example, a refrigerator, a freezer , a fridge freezer, a freezer or a wine storage cabinet.
  • the vacuum insulation panel has only a low intrinsic rigidity, which can lead to distortions or deformations of the vacuum insulation panel during the foaming process, which takes place under pressure and heat.
  • the vacuum insulation panel to increase its component stiffness by means of brackets can be enclosed closed ring.
  • the vacuum insulation panel can also be attached via the headband on the inner and / or outer wall. In this way, both side surfaces of the vacuum insulation panel are enclosed like a cage, whereby shape and / or position changes of the vacuum insulation panel during foaming can be better avoided. Accordingly, a bulging or a sign of these deformations on the outer wall can be prevented, which can usually be made of a very thin sheet metal material.
  • the vacuum insulation panel can be arranged between two retaining clips.
  • the vacuum insulation panel can be clamped under the action of clamping forces between the two brackets, whereby the dimensional stability of the vacuum insulation panel is increased. It is favorable in terms of installation, if the headband and the vacuum insulation panel can already be assembled separately outside the wall gap to form a pre-assembly unit. The pre-assembly unit consisting of the retaining clips and the vacuum insulation panel is then inserted into the wall gap in a further production step before the foaming process. To simplify the assembly of the headband with the vacuum insulation panel, the headband can be made adjustable to each other. Thus, in an open position, the vacuum insulation panel can be easily inserted between the two brackets.
  • the headband can be brought together to form a closed position in which the vacuum insulation panel is surrounded by the retaining clips annular. Additional spring elements may be provided between the retaining clips and the vacuum insulation panel in order to act elastically on the clamped vacuum insulation panel with the above-mentioned tension forces.
  • the two headband may be materially and / or integrally connected to each other via a film hinge.
  • the film hinge forms a folding axis, around which the two brackets can be folded.
  • the headband can be connected at their ends remote from the hinge, for example via any connector.
  • the two retaining clips can also be realized as separate components, which can likewise be joined together, for example via plug connections.
  • Such separate headband may preferably be designed as a common part in order to reduce the production cost.
  • the two brackets cage the vacuum insulation panel, whereby its inherent rigidity is increased. As a result, the adverse changes in shape and position during the foaming process can be prevented.

  • 1 to 5 are formed as mutually separate components which can be joined together at their ends via a locking connection 21 described later, to form an annularly closed intermediate space 23 (FIGS. 2 and 3). in which the vacuum insulation panel 13 is arranged.
  • the latching partners of the respective latching connection 21 between the two retaining clips 15, 16 consist of a latching channel 25, in which a latching element 27 can be inserted. At the opposite contact surfaces between the inner wall of the latching channel 25 and the latching element 27 corresponding sawtooth profiles are formed. Depending on their pitches, therefore, the two brackets 15, 16 for a fine adjustment vacuum insulation panels 13 record different gap width.
