Definitions

  • the invention relates to a refrigeration device, such as a household refrigerator or freezer or the like, with a heat-insulating housing which has at least one storage space and which is formed from an inner and an outer cladding with heat insulation material introduced therebetween and which has an access opening covered by a door. the edge of which serves as a support and magnetic anchor for a magnetic seal arranged all around the door.
  • refrigerator housings with a U-shaped outer cladding are known, in which the two side walls and the ceiling are coherent and are made from a sheet metal plate.
  • the wall sections of this outer cladding are also each provided on the door side with an angled section which has miter cuts at their transition points to one another and which serves as a magnetic armature for a magnetic seal arranged on the appliance door.
  • a crossmember formed from ferromagnetic sheet metal is provided as a magnetic anchor in a housing constructed in this way, the length of which approximately corresponds to the clear width between the bends provided on the side walls.
  • Both housing constructions have the disadvantage that the support surfaces serving as magnetic anchors are either part of a separate housing section or are largely decoupled from one another due to manufacturing processes due to material cuts, so that there is a risk that the support surfaces for the magnetic seal will have different height levels due to manufacturing tolerances.
  • This means that the magnetic seal does not lie tightly around the bearing surfaces and thus, depending on the system achieved, a different amount of warm air penetrates into the refrigeration area of the refrigeration device, which in addition to premature icing of the heat exchange surfaces in the refrigeration area, leads to a not inconsiderable increase in energy consumption for the refrigeration device is caused.
  • the invention has for its object to provide a heat-insulating housing for a refrigerator according to the preamble of claim 1, in which the disadvantages of the prior art are avoided by simple, constructive measures and a sealing system of the magnetic seal is ensured.
  • the ferromagnetic edge serving as an anchor for the magnetic seal is formed from integrally connected edge sections which provide a continuous contact surface and are arranged largely at the same height as one another.
  • the solution according to the invention produces a support edge which serves as a ferromagnetic armature for the magnetic seal and which has the same height level without any cost-intensive adjustment measures and in particular at the transition points of the individual edge sections, so that a circumferentially tight contact of the magnetic seal on this contact edge is ensured. In this way, the undesired penetration of warm air into the cold room is avoided and the energy consumption of the refrigerator is significantly reduced.
  • edge is arranged in an at least door-side by the formation of the access opening and there is produced as the outer cladding ferromagnetic sheet metal.
  • such a solution has the advantage that the width of the edge is largely maintained by cutting out the access opening, so that a secure support of the magnetic seal on the edge is ensured in all manufacturing-related tolerance positions of the cooling device.
  • such a construction ensures that the support edge for the magnetic seal can be connected to the housing as far as possible in a form-accurate and dimensionally stable manner.
  • the sheet metal plate having the edge is designed as a U-profile, the legs of which serve as side walls and the yoke connecting the legs and provided with the access opening serves as the outer cladding.
  • the number of parts for the outer cladding and thus the heat-insulating housing is significantly reduced and, at the same time, the manufacturing and assembly effort for the heat-insulating housing is reduced. Furthermore, a particularly precise assignment of the access opening to the side walls is achieved without the use of a manufacturing device required for this purpose by means of an outer lining of this type. In addition, the external stiffness of the heat-insulating housing is further improved.
  • the floor, the ceiling or the rear wall of the outer cladding can be assigned and attached to it, if after a a further advantageous embodiment of the subject matter of the invention, it is provided that the sheet metal plate serving as the outer cladding is provided with bends for the arrangement of a wall serving as the floor or ceiling or rear wall.
  • An access opening is particularly simple to manufacture, but with high manufacturing accuracy, if, according to a further advantageous embodiment of the subject matter of the invention, it is provided that the access opening is produced by a cutout in the sheet metal plate which corresponds at least approximately to its dimensions.
  • An outer cladding is particularly optimized in terms of material and costs if, according to a next advantageous embodiment of the object of the invention, it is provided that the cutout in the sheet metal plate for the access opening is designed as a floor, as a ceiling or as a rear wall for the outer cladding.
  • the edge is provided on its side facing the inner lining with a circumferentially arranged heating line.
  • a particularly effective heater can be arranged in a particularly simple manner on the housing to prevent condensation at the opening edge of the heat-insulating housing.
  • the outer cladding 22 is shaped into a profile with a U-shaped cross section, the shape of which is created by a corresponding bending of a ferromagnetic sheet metal plate and the legs 23 serving as side walls for the outer cladding 22 are the lateral lateral surfaces for the heat-insulating housing 19 form.
  • the legs 23 of the outer cladding 22 are connected to one another by a wall 24 forming the yoke of the U-profile, which has two rectangular openings 25 and 26, the dimensions of which correspond to the dimensions of the access openings 17 and 18 of the normal cooling compartment 15 or the freezer compartment 16 are largely adapted.
  • the edge 27, with its inner side facing the thermal insulation 21, also serves as a support surface for a heating line 29, which prevents condensation and which is arranged around its edge sections and which can be designed, for example, as a hot gas pipeline and which in the transition from the edge 27 to the outer surfaces of the outer cladding 22 is fixed by a corresponding shaping of the free edge sections of the inner lining 20, the inner lining 22 being sealed towards the edge 27 with common sealants, such as adhesive, putty, adhesive tape, etc. (see FIG. 3).
  • the sheet metal sections cut out of the wall 24 to produce the edge 27 and thus to produce the openings 25 and 26 serve to form a ceiling wall 30 and a bottom wall 31, the sheet metal section corresponding to the opening 25 being used to form the ceiling wall 30 during which Breakthrough 26 corresponding Sheet metal cutout serves to produce the bottom wall 31.
  • the U-shaped outer cladding 22 is provided on both ends with angled portions 32 directed towards the heat insulation material 21, which serve as a support surface for the positionally accurate attachment of the top wall 30 and the bottom wall 31 to the U. -shaped curved outer panel 22 is used.
  • Such bends 32 are also provided on the free ends of the legs 23 facing away from the openings 25 and 26 for mounting a rear wall (not shown here) for the outer cladding 22.
  • a bottom wall 35 can be produced in deviation from the embodiment variant described in FIG. 2 by angling the sheet metal section required to produce the opening 26 around its lower horizontal edge section.
  • the bottom walls 31 and 35 are angled in steps at their end facing the rear wall of the outer cladding, which results in a niche accessible from the outside.
  • the outer cladding according to the invention can also be used on a household refrigerator or freezer, each with a storage space, it being possible for the generation of the support edge for the magnetic seal from the sheet metal section to be cut out of a U-shaped profile sheet metal sheet as a skin condenser.
  • the support edge 27 for the magnetic seals 13 and 14 can also be formed by a frame profile that includes all edge sections of the edge 27 be, which could be fixed, for example, in a receiving groove arranged on the door on the inner lining 20.
