Definitions

  • the invention relates to a refrigeration device with heat-insulating components, such as a heat-insulating housing, a heat-insulating door or the like with a heat insulation layer produced by foaming between an inner and an outer cladding, into which a receiving pocket serving for the insertion of components such as controllers, lamps or the like protrudes, which has an opening for the introduction of the components and which sits in a cutout of the inner or outer cladding.

  • the sealing means resiliently applied to the edges of the cutout due to the pretensioning, the area between the receiving pocket and the cutout is securely sealed against the escape of heat insulation material even if the wall having the cutout shows fluctuations in wall thickness, as is the case, for example, with deep drawing a refrigerated goods container produced in the plastic board can be the case. Since a secure seal against the heat insulation material entered in liquid starting components is achieved at the transition point between the receiving pocket and the cutout even in the case of fluctuations in the wall thickness of the walls having the cutout, not only is the manufacturing safety of the heat-insulating components significantly increased, but also their manufacturing costs are significantly reduced, since the additional costs caused by the rework to eliminate the foam exits are eliminated.
  • the elimination of this rework also means a significant reduction in the manufacturing time for the heat-insulating components.

  • the receiving pocket 20 has at its free end facing the opening 21, on its outside facing away from the receiving region 22, a circumferentially arranged edge 26 which is inclined towards the body of the receiving pocket 20 and thus towards the side walls 24 thereof.
  • the edge 26 is weakened in the area of its connection to the side walls 24 in order to achieve certain spring properties with regard to its wall thickness and is provided with an edge 27 of similar shape from its free end spaced from the outside 25.
  • a locking lug 28 which is molded onto the latter and whose distance a from the edge 27 of the edge 26, which is similar to the cutting edge, is dimensioned slightly less than the wall thickness of the inner lining 15.

  • the former is inserted into the cutout 16 in the direction of the arrow, namely with its rear wall 23 ahead, before the foaming process of the housing 10 and shifted in the direction of the arrow until the latching lugs 28 face the edge 26 Engage the steeper end on the side of the inner lining 15 facing it.
  • the peripheral edge 26 is deflected against its inclination, so that the cutting-like edge 27 provided at its free end rests with a certain pretensioning force on the inside of the inner lining 15 facing the normal cooling compartment 12 and surrounds the cutout 16 in a frame-like sealing manner.
  • This frame-like elastic sealing of the cutout 16 against the receiving pocket 20 reliably prevents the thermal insulation material 14 introduced in liquid starting components from escaping at the interface. Contrary to the illustrated and described exemplary embodiment, it is also possible to insert such a receiving pocket in a sealing manner in an end section of the cooling device housing, in order to be able to arrange controller components that can be operated from the outside, for example.

Abstract

L'invention concerne un appareil réfrigérant comprenant des composants calorifuges, tels qu'un boîtier (10) calorifuge doté d'une couche d'isolation thermique (14) qui est produite par moussage entre un revêtement interne et un revêtement externe et de laquelle une poche (20) fait saillie. Cette poche sert à introduire des composants et qui présente un côté ouvert destiné à l'introduction des composants et qui se situe dans une section du revêtement interne ou externe. La poche présente, côté ouvert, un bord (26) qui suit le contour externe de la poche et s'éloigne de la zone de réception. Ce bord est doté de moyens (27) qui sont en contact élastique avec la bordure de la section et ce, en dehors de la couche calorifuge, lorsque la poche se trouve dans sa position terminale et qui assurent l'étanchéité de la poche vis-à-vis de cette section.
