Definitions

  • the present invention relates to a backing part for mounting on a wall, in particular for foam-side mounting on a wall of a refrigeration device, in which on a wall facing the front of the backing part a chamber is recessed.
  • Such backing parts are used in refrigeration equipment for various purposes, usually to cover a foam-cracked opening in the refrigerator wall foam-tight.
  • an anchoring section of a built-in part can engage in the chamber of the backing part in order to anchor the built-in part to the refrigeration device wall; it may also be provided in the chamber, for example, a switch, of which a slide extends through the opening of the refrigerator wall, to allow actuation of the switch coupled to the opening and closing of a door of the refrigerator.
  • the backing part In order to create a foam-tight contact between the backing part and the refrigerator wall, the backing part is conventionally often surrounded by a circumferential elastic sealing lip which is pressed against the refrigerator wall.
  • a problem of such a sealing lip is that a uniform contact pressure of the sealing lip to the refrigeration appliance wall can be achieved substantially only if the sealing lip extends in a circular or elliptical manner around the backing part.
  • the sealing lip In a backing member of rectangular outline, when linear lip portions extend along the sides of the backing member, the sealing lip has high rigidity at the corners where two rectilinear portions of the lip meet; in the middle of the rectilinear sections, the rigidity of the lip is significantly lower and thus compromises the reliability of the seal.
  • the object of the invention is to provide a backing part, which is foam-mounted on a refrigerator wall and in which a recessed at a front first chamber is protected against the ingress of foam, if it penetrates between the wall and the front of the backing.
  • auxiliary chambers are recessed. These auxiliary chambers give foam between the front of the backing part and the refrigerator wall the opportunity to expand before reaching the centrally located first chamber.
  • the ability to expand into the auxiliary chamber reduces the rate at which the foam penetrates toward the central chamber; with the result that the foam tends to solidify in the auxiliary chambers, hindering its further penetration to the central chamber, if not stopping it.
  • the front is suitably surrounded by a circumferential elastic sealing lip.
  • the sealing lip is preferably wavy at the corners.
  • the auxiliary chambers are preferably arranged so that a straight line extending from one corner of the front to the first chamber, a plurality of auxiliary chambers so that they can gradually fill with foam before foam can reach the first chamber.
  • electrical plug contacts are preferably arranged on a bottom side of the first chamber.
  • the electrical component may be considered as part of the backing member of the invention.
  • the shape of the first chamber and a body of the electrical component are adapted to each other, that the body is guided in the first chamber on a Einsteckweg and complementary to the plug contacts of the backing part plug contacts of the electrical component in the insertion on the plug contacts of the backing part are aligned , So grab the end of the insertion path Plug contacts of the body and the first chamber into each other, which speeds up and simplifies the assembly of the electrical component.
  • a cable In order to supply the plug contacts or the electrical component electrically, a cable must be passed through the backing part. In order to prevent access of foam via the cable feedthrough into the first chamber, the cable is preferably guided in multiple curves through a labyrinth chamber with which the first chamber communicates.
  • Plug connectors of the cable are preferably form-fittingly placeable on at least one passage opening between the first chamber and the labyrinth chamber, so that they can engage with complementary plug connectors of the electrical component without being displaced upon insertion of the electrical component.
  • the cable inlet opening is preferably formed on a surface of the backing part facing the refrigeration appliance wall and spaced therefrom.
  • Particularly preferred is a structure in which the first chamber and the auxiliary chambers are housed in a front housing and the labyrinth chambers in a rear housing of the backing part, wherein the cable entry opening is arranged in the rear housing opposite to a rear side of the front housing.
  • At least one clamping fork is provided for anchoring the cable to an outer surface of the backing part.
  • a clamping fork makes it possible, on the one hand, to fix the cable at the height of the cable entry opening of the labyrinth chamber and thereby to make it difficult for foam to enter the labyrinth chamber.
  • increased by laying in the terminal forks length of the cable between the connectors on the one hand and a cooled in contact with an interior of the refrigerator section of the cable on the other hand causes a reduction in
  • one of the terminal forks is disposed on a neck portion connecting the front and rear housings of the backing member.
  • the latter is preferably closed by a lid.
  • This lid is preferably connected to the rear housing by a film hinge.

  • a narrow circumferential ridge 13 is formed, which is folded in the closed state of the rear housing 3, when the lid 1 1 by means of the film hinge 12 on the lower part 5, foam-tight in a circumferential groove 14 at the upper edges of Walls 8, 9, 10 engages.
  • the lid 1 1 carries a plurality of latching hooks 15 which engage in the closed position of the lid on from the sides 8 and the rear wall 9 projecting locking lugs 16 and lock the lid 1 1 in the closed position.

Subsequently, the cable 17 is pressed into the clamping fork 18 of the neck portion 4 and the lid 1 1 folded on the lower part 5 and locked.

  • This corrugated edge course allows the sealing lip 30, a pressure that keeps the backing part 1 pressed against a wall to give way at the corners by flattening.
  • a substantially uniform distribution of the contact pressure over the entire length of the sealing lip 30 and thus a good sealing effect despite a deviating greatly from the circular cross-section of the front housing 2 can be achieved.
