Definitions

  • the present invention relates to a refrigerator housing with a pipe feedthrough, in particular for the discharge of condensate from an interior of the housing, and a method for mounting such a housing.
  • this pipe comprises an inner pipe piece, which is attached to a piercing of the inner container of the refrigerator and extends from there through the insulating material layer of the housing wall, and an outer pipe piece, which is inserted through a cut into a solid outer skin of the housing wall opening and on the inner pipe section is pushed.
  • the aim of the present invention is to reduce the workload in the assembly of such a refrigeration device housing.
  • the object is achieved, on the one hand, by providing, in the case of a refrigeration appliance housing, a housing wall which comprises at least one outer skin and an insulation layer delimited by the outer skin, and a pipe penetration which intersects the housing wall and which extends inside the insulation layer and adjoins an inner side of the outer skin Feedthrough part and an opening of the outer skin crossing and engaging in the inner passage part outer leadthrough part comprises, a displaced from the opening piece of the outer skin is received in a cavity of the inner leadthrough part.
  • a cavity containing the Piece of outer skin can absorb, at least eliminates the need to remove the piece outer skin after cutting out. In addition, it can even be dispensed with, the piece completely from the rest of the outer skin to solve; a residual connection may remain, which further facilitates the creation of the opening.
  • the inner leadthrough part preferably comprises an inner pipe piece projecting into the hollow space and the outer leadthrough part has an outer pipe piece plugged onto the inner pipe piece.
  • Insulation material can be kept away from the cavity when it is bounded by a cup of the inner feedthrough part, of which an edge rests against the outer skin.
  • the inner tube then preferably passes through a bottom of the cup.
  • a support flange extending from the edge of the cup to the outer skin stabilizes the position of the inner leadthrough part, in particular if the insulating layer is produced by foaming in a manner known per se.
  • the outer tube piece is expediently provided with a cutting tip.
  • the opening can be first cut by pressing the tip of this end face on a part of its circumference; to the extent that the outer tube is pushed further into the wall, the opening is continuously widened until finally the outer tube fits through.
  • the outer pipe piece is preferably latched to the inner passage part.
  • cooperating latching steps can be formed on an inner surface of the outer tube piece or on an outer surface of the inner tube piece.
  • the outer leadthrough part preferably comprises a cover flange which bears against the outside of the outer skin.
  • a cover flange which bears against the outside of the outer skin.
  • At least one screw opening is preferably provided on the cover flange and at least one threaded hole facing the support flange faces the threaded hole.
  • the outer tube section expediently has a drip edge, which is spaced from the outer skin, in order to prevent water draining via the tube feedthrough from coming into contact with the outer skin.
  • a method for mounting a pipe feedthrough in a refrigeration appliance housing comprising the steps of: a) providing a refrigeration appliance housing, wherein a housing wall comprises at least one outer skin and an insulating layer bounded by the outer skin and an inner feedthrough part extends in the insulating layer and rests against an inner side of the outer skin; b) tearing open an opening in the outer skin by pressing on an outer lead-through part; c) inserting an outer tube piece of the outer lead-through part in the opening and the inner passage part.
  • step a) preferably comprises producing a marking indicating the position of the inner lead-through part on the outer side of the outer skin. If the insulating layer is produced by foaming, it is expedient to also produce the marking by the foaming. This is possible in different ways.
  • the pressure acting from the inside against the outer skin must be compensated by a foam mold held from the outside. If the material of the outer skin has a surface texture that can be changed by the process conditions such as, in particular, pressure or temperature that is variable during foaming, then the position of the cavity of the inner throughfeed part on the outer skin becomes visible after foaming because it is not exposed to the same process conditions as the rest of the process Outer skin and its surface texture is therefore less changed.
  • the foaming form of sublimity which faces the cavity during foaming and pushes the outer skin slightly into the cavity. This also makes the edge of the cavity can be seen from the outside after foaming.
  • Figure 1 is an exploded perspective view of the outer and inner passage part of a pipe feedthrough according to the invention, as well as a piece of a rear wall board, which forms an outer skin of a housing wall of a refrigerator.
  • Figure 2 is a section through the two feedthroughs before their assembly along a vertical plane.
  • Figure 3 is a partial section through the rear wall of the refrigerator with fully assembled pipe feedthrough.
  • Fig. 4 is a section along the plane IV-IV of Fig. 3;
  • Fig. 5 is a partial section through the rear wall of the refrigerator shortly before foaming.
  • FIGs 1 and 2 show the parts of a pipe penetration in a perspective view and in longitudinal section.
  • An inner passage part 1 comprises a pipe section 2 of non-circular, preferably elliptical cross-section, which carries an angled connecting flange 3 at one end.
  • the connecting flange 3 is provided to foam cover a puncture of a formed in the inner container of a refrigerator below an evaporator condensate drainage channel and hineinzuterrorism from the puncture effluent discharge water into the pipe section 2.
  • the pipe section 2 extends obliquely downward through a bottom 4 of a cup 5, the obliquely cut edge abuts the inside of a rear wall board 6 of the refrigerator.
  • a outgoing from the edge of the cup 5 support flange 7 is located at a large area on the back wall board 6.
  • a lower end of the pipe section 2 is located in the interior of the cup 5.
  • Cup 5, support flange 7 and pipe section 2 are injection molded in one piece from plastic.
  • FIG. 1 In the state shown in Figures 1 and 2, the rear wall board 6 is closed; an ellipse designated by 8 in FIG. 1 represents a marking applied to the rear wall board 6, indicating at which point the outer passage 11 is to be mounted. For the formation of the mark 8 reference is made to FIG. 5.
  • the outer lead-through part 1 1 is injection-molded in one piece from plastic and comprises a cover flange 13, a tube section 12 extending obliquely upward from the cover flange 13, and a drainage contour 14 at the opposite side of the cover flange 13 from the tube section 12.
  • the pipe section 12 is provided so as to pierce the backboard 6 at the location of the mark 8 and push it inside the cup 5 on the end of the Postpone pipe section 2.
  • the pipe section 12 has a sharp-edged end face 15, which extends obliquely to the insertion direction of the pipe sections 2, 12.
  • the cross sections of the pipe sections 2, 12 are adapted to each other, so that the pipe section 12 with minimal play and rotationally fixed on the pipe section 2 can be plugged.
  • projecting locking lugs 16 are formed on the pipe section 12 in its interior, and to these detents 16 complementary recesses 9 are located on the outer sides of the pipe section 2, as shown in Fig. 4.
  • the pipe sections 2, 12 are pushed into each other so far that the support flange 7 and the cover 13 pinch between them the rear wall board 6, lock the locking lugs 16 in the recesses 9 and anchoring the bushing parts 1, 1 1 undetachably to each other.
  • Pipe section 12 penetrates into the cup 5, the crack expands obliquely upward on both sides until it is large enough to pass the pipe section 12 completely.
  • a tongue 10 formed by the crack in the back board 6 pivots upward into the interior of the cup 5 and remains there as in FIG.
