Definitions

  • the invention relates to a refrigerator, in particular a refrigerator and / or freezer, according to the preamble of the first claim.
  • a gas-tight inner container is also located in a gas-tight outer housing, the free space between the outer housing and inner container being filled with an insulating material serving as a proppant.
  • the outer housing and inner container are connected to one another in a gas-tight manner at their edge zones, so that the cavity filled with heat insulating material can also be evacuated.
  • the inner walls of the inner container intended to hold goods to be cooled are smooth.
  • Such a refrigerator with an integrated freezer compartment is also known from EP 0 071 090 A1.
  • the invention has for its object to take measures in a refrigerator according to the preamble of the first claim, by which it is possible in a simple manner to accommodate built-in parts in the refrigerator.
  • the holding elements are in particular arranged closely adjacent to wall surfaces of the container or the shell, so that they can be supported on them.
  • the holding elements are designed as mutually parallel frames which rest against vertical walls of the container or the shell and which are supported on the lower horizontal floor surface or other wall parts projecting horizontally into the cooling space.
  • the frames are preferably combined via horizontal connecting webs to form a cage, which can be placed in the inner container in particular without any aids.
  • supports for storage plates or storage racks can be easily formed.
  • retaining tabs, supports or guides for evaporator boards or evaporator grids can also be provided thereon.
  • guides for shelves or evaporator grids or the like horizontally extending guide strips or guide grooves can be formed on horizontal webs be.
  • fastening means for lighting elements and / or regulating or control elements are also provided on the holding elements.
  • a fastening means for a lighting fixture is arranged on a connecting web between the frames. To hold the holding elements in a self-locking manner, they can be clamped under mechanical pretension between wall parts of the container or the shell. The frictional force thus generated then prevents these fasteners from automatically moving relative to the wall parts assigned to them.
  • the frame or the cage can be made in one piece as a whole. To adapt to different inner container sizes, however, it is expedient to assemble these holding elements from individual parts.
  • an additional intermediate frame can be provided between two frames if shortened supports or other built-in parts are to be used. It is expedient to hold the respective intermediate frame on connecting webs of the cage.
  • a door 2, 4 is hinged to an outer housing 1, an inner container 3 with smooth walls being located in the outer housing 1 and an inner door shell 4 in the door 2, 4.
  • a heat insulating material 5 which serves as a support means and which prevents the boundary walls from bending when the cavity is additionally evacuated.
  • self-supporting holding elements 6 are inserted into the inner container 3 or in the inner door shell, which are located on the horizontal leg 7 of a rear molding or on the bottom 8 of the inner container and in the inner door shell support on the lower horizontal edge section and are made of plastic profiles (Fig. 1 and 2) or of wire. These parts 7, 8 absorb the weight forces of the holding elements 6 which may be loaded with installation elements.
  • the container 3 like the inner door shell 4, but also the outer housing 1 and the outer door shell 2, is made of gas diffusion-tight, smooth metal sheet. In particular, 2.4 stainless steel is used for the inner container 3 as for the door.
  • the holding elements 6 are in particular designed as a ladder-like frame 6.1, which stand up on the horizontal parts 7, 8 and likewise have plastic profiles or wire webs 6.2 (FIGS. 3 and 4) which are designed in the manner of rungs.
  • the frames 6.1 lean closely against the rear wall 12 or the vertical side walls 10 of the inner container 3 or against the inner door shell 4.
  • the horizontal webs 6.2 can serve as supports for storage plates or storage grids on which goods to be cooled can be placed.
  • These webs 6.2 can be provided as guide strips or with guide grooves and, in accordance with FIGS. 3 and 4, are formed in pairs as guide strips in the manner of guide grooves into which these shelves can be inserted from the door.
  • Evaporator boards or evaporator grids are also provided.
  • At least one retaining tab 6.3 can also be provided on the rear spars of the frame 6.1, on which or between which an evaporator plate 11 can be fixed.
  • the webs 6.2 can also carry pull-out refrigerated goods baskets in freezers.
  • the holding elements are to represent a rigid structure in themselves, it is expedient to combine them into a prefabricated cage according to FIG. 1.
  • This cage can be prefabricated in one piece or completely if a large number of identical elements is required in series production. Otherwise, it may be expedient to only produce the frames 6.1 in one piece with the webs 6.2 if only an adjustment in width is necessary (FIG. 2.5). Otherwise, the individual elements are made from individual parts, for example by plugging together, gluing or welding to match the internal dimensions of the inner container 3 or the inner door shell 4.
  • the holding elements are designed as cages, the frames 6.1 are held together via connecting webs 6.4. It is sufficient if in particular the rear spars of the frames are connected to these connecting webs 6.4.
  • the upper or lower end of the vertical spars facing the door 2.4 can also be connected to such a connecting web 6.4 without making it more difficult to access the inner container 3. Given the small depth of the inner door shell 4, it is sufficient if the spars adjacent to it are held together with a connecting web 6.4.
  • the connecting webs 6.4 can additionally be provided with elements 6.5, which can in particular be a housing for interior lighting. If the holding element is attached to the front upper connecting web 6.4, it can Display elements or control means are provided. It is also expedient to arrange a controller and / or lighting combination between two horizontal, sufficiently spaced webs 6.2.
  • the webs 6.2 are bow-shaped or bridge-shaped and protrude into the interior of the inner container 3. 3 and 4 form guide groove replicas into which storage plates or grids and the like can be inserted with their edges.
  • the holding elements 6, in particular the frame 6.1 or the cage formed therefrom, can be matched to the inner dimensions of the inner container 3 or the inner door shell 4 in such a way that they are clamped under mechanical prestress between adjacent wall parts and are thus held by frictional engagement.
  • an intermediate frame between two frames 6.1, which then rest in particular on side walls 10 of the container 3 or the shell 4.
  • This intermediate frame can correspond wholly or partially to the frame 6.1 and serve for the storage of shelves or grids and the like, which do not extend across the entire width of the inner container 3, that is to say not from one outer frame 6.1 to the other outer frame 6.1.
  • This or several of these intermediate frames are held on connecting webs 6.4, so that no additional parts are required for this either.
  • the self-supporting holding elements 6 designed as plastic profile bars or wire gratings provide a possibility of being able to hold the installation parts required within a cooling space without having to carry out any damage or deformation of the walls in question. It is also possible to use a holding element for fastening a drip channel 6.7, which is below the evaporator 11 and collects condensation water dripping from the latter. This drip gutter 6.7 can also be detachably attached to the frame or a holding element or the evaporator 11.
