[0045] FIG. 5 shows a horizontal section through a part of the inner compartment 10. The inner compartment 10 has at least one inner edge 54 on a side 52 facing the storage space 12. The inner edge 54 has an edge radius 104. The edge radius 104 of the inner edge 54 is 1.5 mm. The inner edge 54 shown is merely an example of further inner edges of the inner compartment 10 which are arranged on other parts of the inner compartment 10 and which also may have an edge radius 104 of 1.5 mm or less. The edge radius 104 is, in particular, at least 10% smaller than a minimum edge radius 104 which may be produced by conventional deep-drawing methods.

[0046] FIG. 6 shows schematically, and by way of example for all further insulating elements 32, 70, 72, 74, 82, the prefabricated insulating element 18 and a part of the outer casing 42 with the functional unit 50. The insulating element 18 is of panel-like configuration. The insulating element 18 is produced in a continuous foaming process. The insulating element 18 is produced in an external panel production system for producing insulating elements 18. The insulating element 18 may be pressed to form a molded body. On a side 38 of the insulating element 18 facing the inner compartment 10, the insulating element 18 has a shape, in particular a surface shape, which is adapted to an outer shape of the side 20 of the inner compartment 10 directed away from the storage space 12 (see FIG. 3).

The partial insulating elements 34, 36, 68 are positioned vertically one above the other in the assembled state of the refrigeration appliance device 58 in the installation direction 88 of the refrigeration appliance device 58. The insulating element 18 is divided into the separate partial insulating elements 34, 36, 68 in the installation direction 88. Alternatively or additionally, the insulating element 18 may be divided into, in particular, further separate partial insulating elements perpendicular to the installation direction 88. The partial insulating elements 34, 36, 68 are able to be form-lockingly connected to one another. The partial insulating elements 34, 36, 68 have form-locking-connection elements 112 which correspond to one another and which engage in one another to connect two respective partial insulating elements 34, 36, 68.
