Problems solved by technology

As a result, the upper end of the inner chamber of the refrigeration unit, i.e. at the height of the upper rounding, cannot be effectively cooled and undesired temperature differences can occur in the inner chamber

Embodiment Construction

[0019] Fig. 1 shows a partial sectional view of an inner storage 1' of a conventional refrigeration device. Visible are parts of the top cover 2' and the rear wall 3' of the inner receptacle, and the rounding 4' connecting the two. The radius of curvature of the rounding 4' is chosen such that it is sufficiently safe to avoid fractures between the top cover 2' and the rear wall 3' during the forming of the inner receptacle 1'. A typical radius of curvature required for this purpose is 2 cm. The cold wall evaporator 5' arranged on the rear wall 3 extends to the dotted line position where the vertical rear wall 3' will transition to the rounded 4'. The upper edge of the evaporator terminates at a distance h' of about 2 cm below the top cover 2'.

[0020] Fig. 2 shows a sectional view of the same corner of the storage container 1 in the refrigeration device of the present invention. In this device, the structure between the top cover 2 and the rear wall 3 is successively a fir...

Abstract

The invention relates to a refrigerating appliance comprising a heat-insulating housing and an inner chamber which is surrounded by said housing. The housing is provided with an inner container (1) and an outer wall which together define an intermediate chamber, and an evaporator (5) which is arranged in the intermediate chamber and is in thermal contact with a vertical wall (3) of the inner container. At least one plane oblique wall surface (6) is formed between the vertical wall (3) and a cover (2) of the inner container (1), the evaporator (5) extending on said surface.

Description

technical field [0001] The invention relates to a refrigeration device having a heat-insulated outer shell and an inner chamber surrounded by the outer shell. The housing has an inner reservoir and an outer wall defining a common cavity, and an evaporator disposed within the cavity and in thermal contact with the vertical wall of the inner reservoir. Such evaporators, which are also known and are called cold-wall evaporators, are mainly attached to the outer sides of the inner container. Background technique [0002] The inner storage device of this kind of refrigeration equipment is mainly made of plastic plate material by deep drawing method. If it is to be drawn from a flat sheet of material that it is essentially cuboid and resembles a receptacle in a refrigeration appliance, the material will be drawn considerably, particularly in the region forming the edges of the inner receptacle. In order to prevent the edges from being broken, the edges are usually rounded, and t...
