Definitions

  • the invention relates to a heat-insulating housing for a household cooling or freezer with a plastic inner lining and a spaced apart Outer jacket between which a thermal insulation layer is foamed and between which at least one current or liquid-carrying line or the like is arranged, which from an opening in the outer jacket led out of the space and in the opening with sealing agents to prevent the exit of heat insulation material is sealed.
  • the difficult installation of the sealing plug does not always ensure that it is properly installed so that foam escapes the supposedly sealed breakthroughs can occur.
  • GB-A-2 166 859 discloses a housing of a fridge-freezer combination, in the rear wall, inside the thermal insulation, a condensate drain pipe is laid, the drain-side end through an opening in an outer panel serving wall emerges.
  • a condensate drain pipe is laid, the drain-side end through an opening in an outer panel serving wall emerges.
  • a sealing ring is provided both on the heat insulation side and on the outside.
  • US Pat. No. 4,165,105 also shows and describes a cooling device The distance between its inner and outer cladding bridging grommet, which serves a pipeline from the cold room over the thermal insulation of the cooling device in the Overpass outdoor area.
  • the one used for this purpose the end sections of the tubular bushing penetrate the inner or outer cladding in a breakthrough that has a flange-like, shell side provided at the end portions of the bushing sealing lip is sealed to prevent it from being introduced into liquid starting components Thermal insulation material escapes through the openings.
  • a pipe Within of the lead-through body, a pipe is arranged, which with Sealing plug is sealed with respect to the bushing body. The sealing plugs have no sealing effect on the thermal insulation material.
  • the invention has for its object in a heat-insulating housing according to the preamble of claim 1 with simple constructive Measures the sealing for foam-side laid and out of the housing to lead out leads.
  • the opening as sleeve-like approach is formed, within which the line is arranged and to prevent the escape of thermal insulation material from at least one largely adapted to the contour of the approach and of this elastic deformed sealing body is sealingly surrounded, which is at least approximately has the height of the approach and in this positive and / or non-positive is held.
  • the sealing body is over the height of the approach guided and from its inner walls essentially uniformly elastic compressed so that the sealing body on the height of the approach both at its Inner surfaces and also on the outer surface of the line is pressed in a sealing manner, with a constriction by guiding the sealing body over the height of the neck the sealing body is avoided, so that it effortlessly and quickly in the Approach is insertable.
  • the leadership achieved as a result of the approach for the sealing body ensures that it is targeted to its sealing position is supplied so that unintentionally caused by the assembly of the sealing body Leakage between the pipe to be sealed and its removal are always safely avoided from the housing.
  • the sleeve-like approach on its the outer jacket facing, at least approximately flush with this final end at least has a stop element for supporting the elastic sealing body.
  • Such a configuration of the solution according to the invention makes the sealing body additionally by the as thermal insulation between the outer jacket and the inner lining of the compressed foam and compressed against the stop element indented, whereby the sealing effect of the sealing body with respect the line surrounded by him and regarding the sleeve-like approach without additional measures is significantly increased.
  • a sealing body is particularly easy to install and handle, if after a next advantageous embodiment of the subject of the invention provided is that the sealing body is designed as a foamed plug.
  • the sealing body and the sleeve-like one are particularly simple and inexpensive to manufacture Approach if according to a last preferred embodiment of the
  • the object of the invention is that the sealing body and the sleeve-like Approach have a circular cross section.
  • the freezer compartment 13 is via a heat-insulating door 15 accessible, which in the closed state together with a heat insulating Housing 16 encloses the freezer compartment 13 in a heat-insulating manner and which is struck on the housing 16.
  • the heat insulating housing 16 includes one the freezer compartment 13 lining plastic inner lining 17, a foamed Thermal insulation layer 18 and an outer cladding serving as an outer jacket 19, which in the area of the housing base as made of plastic injection molding manufactured floor pan 20 is formed.
  • a sleeve-like section Approach trained cable entry 21 This is as to the Floor pan 20 formed with an integrally formed cylindrical tube, the free End protrudes into the heat insulation layer 18 and the bottom tray facing Section flush with the outside and with one of his Opening cross section narrowing stop wall 22 is provided, which over the entire circumference of the inner tube wall is arranged.
  • the as sleeve-like Approach 21 trained leadthrough is used to lead out a between the inner panel 17 and the outer panel 19 within the Thermal insulation layer 18 extending line 21, which in the present case is designed as a suction pipe and before the foaming process by the Plastic inner lining 17 and the outer lining 19 formed space is laid in this.
  • the line 23 is essentially over the entire Length towards the sleeve-like extension 21 from a cylindrical one Surrounding resilient sealing plug 24, which to for this purpose with a through bore 25 running along its axis is provided.
  • the sealing plug 24 is along its entire height with one of its Cutting the wall thickness and ending in the through hole 25 Cutting 26 provided, the parting planes in the unloaded state of the Sealing plug 24 already lie against one another under a certain pretension.
  • the sealing plug 24 which over its Cutting 26 can be applied to the line 23 and this is applied Condition encloses. Following this, the sealing plug 24 is removed from the gap from the sleeve-like extension 21 serving as a leadthrough inserted, the insertion depth and thus the correct position of the sealing plug 24 is signaled by its concern on the stop wall 22.
  • the elastically compressible sealing plug 24 is over its total height and along its outer contour evenly to a predetermined one Dimensionally compressed, which not only prevents foam from escaping Sealing effect between the through hole 25 and the line 23 but also sets a foam seal between the outer surface of the sealing plug 24 and the inner tubular surface of the sleeve-like extension 21 is generated.
