DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] A partial view of the rear wall R of an inner container can be seen in FIG. 1. The bracket 10, consisting of metal, is located in the central region thereof (in the lateral direction). Said bracket comprises a plurality of openings which are spaced apart in the vertical direction and in which a glass base or another base can be suspended.

[0034] The vaporizer or a cold air channel, i.e. a heat sink, is located behind the rear wall R.

[0035] In order to keep the direct contact between the bracket and the rear wall R as small as possible, or to prevent it entirely, the insulation part 20 is provided. This is located between the rear wall R and the bracket 10. Reference sign 40 denotes an optional additional insulation layer or plate, which is arranged between the insulation part 20 and the rear wall R.

[0036] The insulation part 20 is designed in a trough-shaped manner on the rear face thereof, which follows in particular from FIG. 2 (cf. trough-shaped portion W). Other than the trough-shaped portion W which is located between the bracket 10 and the rear wall R, the insulation part 20 comprises a peripheral housing portion G which surrounds the bracket 10 in the peripheral direction, i.e. laterally, as well as at the top and bottom. The cold air, originating from the vaporizer, which flows along behind the rear wall R is denoted by arrows in FIG. 2.

[0037] The trough-shaped portion W thus forms a part of the rear face of the insulation part 20, and the housing portion G forms a frame-like region around the bracket 10.

[0038] FIG. 3 shows a depression V in the inner container or in the rear wall R thereof, into which the insulation part 20 engages by means of a protrusion. The insulation part 20 and the bracket 10 are screwed to the rear wall R.

[0039] FIGS. 4 and 5 show details of a vertical partition wall T, which separates the vaporizer space from the useful space of the cooled interior.

[0040] The insulation part 20 extends from the rear face as far as the front face of the partition wall T, such that there is in principle the possibility for cold air passage from the cold air channel towards the bracket 10, as follows from FIG. 5 and is denoted by the solid arrows. In order to keep this as small as possible, and to keep the air in the cold air channel denoted by the flow arrows, the flow path S is designed in a labyrinthine manner. In this way, the flow resistance for the cold air towards the bracket 10 is of such a magnitude that a large portion of the air remains in the cold air channel (efficiency improvement) and does not flow forwards to the bracket 10.

[0041] The present invention not only reduces the likelihood of the appearance of condensate on the bracket, but rather also prevents or at least slows its corrosion by condensate.
