Definitions

  • the invention relates to a housing according to the preamble of the first claim.
  • a known housing of this type (US-A-2088716) has vertical side walls which are perpendicular to a front opening plane and which are provided with inwardly bent edge strips at their edges associated with the door opening of an inserted inner container, the rear and the top and bottom.
  • the edges of an additional ceiling wall and a floor wall are provided with inwardly bent edge strips, the mutually adjacent bending edges of the side walls and the ceiling wall and the floor wall closely overlapping one another.
  • brackets on the edge strips which are provided for a front flange of the inner container and the rear wall.
  • brackets in the area of the door opening consist of the inwardly angled free edge zones of the edge strips there, while in the area of the rear wall they are formed directly by the edge strips there, against which the rear wall lies flat.
  • Independent insulating plates are inserted in the space between the housing and the inner container.
  • the housing is assembled with the inner container in such a way that the two side walls, the rear wall and the bottom wall are first screwed together using feet.
  • the inner container with the front flange is then inserted from above into this prefabricated housing part, the edge zones of the adjacent edge strips coming into engagement with the front of the front flange.
  • the insulating plates on the floor and on the vertical side walls are also inserted into the outer housing.
  • an intermediate wall which carries the cooling unit, the evaporator of which projects through an opening in the inner container.
  • the housing is then closed with a ceiling wall.
  • a structure of this type is not suitable for modern mass production with foamed heat insulation, since a foam-tight seal is not guaranteed, especially in the upper area.
  • the housing parts must be firmly connected to each other during assembly in different working stages.
  • the invention has for its object to provide a housing according to the preamble of the first claim, which not only enables simplification in manufacture and assembly and a largely foam-tight seal along the housing edges, but also an improved cohesion of the merely plugged walls.
  • the series connection of gaps formed by the edge strips in each case leads to a narrow creepage distance for the insulating foam that practically an insulating foam Completion is guaranteed.
  • the cohesion of the housing is achieved by the direct engagement of the adjacent walls in that the corner area of a wall cut free on a wall is inserted into an adapted gap of the adjacent wall in the area of the associated edge strip. Since this gap extends perpendicular to the level of the associated side wall over the height of the edge strip, the cut-away corner region inserted therein cannot be adjusted in the manner of a joint. As a result, the assembled walls are clearly fixed in their position.
  • their dimensions, at least in the region of the bent edge strips, can be such that, with their own elastic expansion, they bring about a clamping connection between the abutting walls.
  • the wall engaging under an edge strip in the area of overlap with the edge strip of the other wall can have locking lugs which engage in corresponding locking recesses in the associated edge strip of the second wall.
  • the edge strips lying on the outside and once on the inside of the adjacent walls, in conjunction with the holding devices provide support against skewed adjustment of the housing walls in the pre-assembly step before foaming. Manual work, such as screwing or riveting, is not necessary during assembly.
  • side walls 1 and a top wall 2 or bottom wall 3 are provided opposite each other.
  • the walls 1 and 2, 3 are each of identical design and can therefore be manufactured from sheet metal on a profiling line.
  • the walls 1, 2, 3 are each provided on their four edges with inwardly bent edge strips 4, the respectively adjacent bending edges 5 closely overlapping one another.
  • the edge strips of one wall 1 or 2 or 3 come into tight contact with the surfaces of the adjacent wall 2 or 3 or 1. This ensures high stability of the housing structure and a long creepage distance for those to be inserted and foamed into the housing later Thermal insulation mass reached. This results in a sufficiently tight seal between these side walls 1, 2, 3 without any special aids.
  • the edge strips 4 provide mutual support for the walls 1, 2, 3.
  • the bent edge strips 4 are provided on the front edges of the walls 1, 2, 3 adjacent to the door opening as well as on the rear edges with U-shaped plug-in receptacles 6 which run in the longitudinal direction of the edge strips 4 and which serve as holders for a front flange 7 serve an inner container or for a rear wall 8.
  • the clear width of the plug-in receptacles can be somewhat less than the material thickness of the flange 7 or the rear wall 8, so that a certain cohesion of the housing is achieved via these parts before the foaming.
  • the edge strips 4 provided on the front and rear edges can also serve if the clear distance in the area of a bending edge 5 between the front and rear edge strips 4 of one wall is less than the outer length of the respective overlapped second wall is in the non-connected state.
  • the clamping effect of the elastic edge strips 4 can then be exploited.
  • the U-shaped receptacles 6 are otherwise integrally formed on the front or rear edge strips 4.
  • the edge strip 4 with the plug-in receptacle 6 of the side wall 1 is shortened in length according to FIGS. 3 to 5.
  • the edge strip 4, which is provided without a plug-in receptacle and which bears against the side wall 1, is shortened on the ceiling wall 2 by the thickness of the plug-in receptacle 6 reaching into the housing depth. This results in released corner sections 9 in all corner areas of the ceiling wall 2 or the bottom wall 3, which only have the material thickness of the walls 2, 3.
  • the edge strip of the side wall 1 with the plug-in receptacle is shortened by the material thickness of the first wall or of the corner region 9.
  • the cut corner area 9 thus engages in the gap between the edge strip not provided with a plug-in receptacle and the end face of the edge strip 4 running at right angles to it with its plug-in receptacle 6.
  • This plug-in connection which can simultaneously cause a frictional connection , the cohesion of the assembled walls 1, 2, 3 is supported.
  • the front flange 7 of the inner container which also engages in the plug receptacle 6 in this area, supports the foam-tight closure in the corner area.
  • the edge strip 4 can also be mitred with the leg of the plug-in receptacle 6 pointing outwards, so that a largely gap-free collision of the two edge strips 4 is possible.
  • at least one inner leg of the plug-in receptacle can come into contact with the inserted front flange 7 on an edge strip 4 and form a long creepage distance for the foamed-up heat-insulating compound.
  • notches 10 can be provided in the edges of the walls not provided with a plug-in receptacle. Then only locking lugs 11 which snap into the locking recesses 10 need to be arranged on the ceiling wall 2 located below.
  • the height of the locking lugs 11 is adapted to the material thickness of the edge strips.
  • the free edge of the associated edge strip can slide over inclined contact surfaces 12 of the locking lugs, the edge strips 4 being elastically bent out until they snap into place via the locking lugs 11.
  • the locking lugs 11 are provided on a carrier 13 which is fixed on the inside of the associated wall 2.
  • the locking lugs 11 pass through this wall 2.
  • the carrier 13 can have congruent openings 14 in the edge strip 4 or in the wall 2, 3 provided threads have passages 15, can be screwed on the hinge tabs 16 or support feet 17.
