Embodiment Construction

[0018] exist figure 1 In , the reference number 1 indicates the pre-installation of the refrigeration unit. Reference numeral 2 denotes the injection of sealing material to seal seams and / or gaps. Reference numeral 3 designates the injection of insulating foam.

[0019] figure 2 The refrigeration unit shown in is a so-called refrigerator / freezer combination. The inner casing of the refrigerating compartment 7 and the inner casing of the freezing compartment 7 are provided for storing refrigerated and frozen foods. The inner shells 7 , 8 are mounted in a housing which has a cover 4 , two side walls 5 and a rear wall 6 . figure 2 Also shown in is six vacuum suction devices 10 placed on the rear wall 6 . For reasons of clarity, only one injection nozzle 9 for the sealing compound is shown. However, each vacuum suction device 10 is assigned its own assigned injection nozzle 9 . The vacuum suction devices 10 are designed in such a way that they simultaneously form guides f...

Abstract

The invention relates to a method for manufacturing a refrigeration device having: a cooled interior delimited by an inner shell (7, 8); an outer shell (4, 5, 6); and a The space between (7, 8) and the shell (4, 5, 6) into which hardenable insulating foam is injected. According to the invention, before injecting the insulating foam (3), a sealing material is injected into the space (2), said material sealing the seams and / or gaps and preventing the insulating foam from passing through said seams and / or gaps.

Description

technical field [0001] The invention relates to a method for producing a refrigeration device according to the preamble of claim 1 . Background technique [0002] Refrigeration units typically have a cooled interior bounded by easy-to-clean plastic walls. Drawers or shelves for storing cooled or frozen food items are included in the interior. The refrigeration device is surrounded by a housing which protects the device from external influences. A space is provided between the inner and outer plastic walls to ensure that no heat can enter the interior from the outside, said space being filled by injecting insulating foam. For this purpose, the injection opening for the insulating foam is usually provided in the motor compartment of the refrigeration unit close to the rear wall. The insulating foam is dispersed in the space from said injection opening so that it fills the entire interior space evenly, insulating the interior evenly at all points. [0003] During the pre-as...
