(23) The machine compartment top wall 16a has six latching elements 26a which correspond to the corresponding latching elements 28a of the side wall component 14a (cf. FIG. 5). In an assembled state, the latching element 26a is provided so as to be latched with the corresponding latching element 28a of the side wall component 14a (cf. also FIGS. 3 and 5). The latching element 26a is designed as one piece with the machine compartment top wall 16a. In particular, the latching element 16a is formed by a bent bracket of the machine compartment top wall 16a.

(24) The machine compartment top wall 16a has a plurality of cut-outs 48a. At least one cut-out 48a is provided so as in at least one assembly step to allow the insulation material that fills the insulation space 46a to pass through. In particular, at least one cut-out 48a is used as a through-passage for foam when the insulation space 46a is being filled with foam. At least one further cut-out 48a is provided so as in an assembled state to drain off into the machine compartment 44a condensate water that condenses in the cold compartment.

(25) The machine compartment top wall 16a is formed from metal, in the illustrated example, the machine compartment top wall 16a is formed in particular from galvanized steel plate. The machine compartment top wall 16a is designed to be bend-resistant. In particular, the machine compartment top wall 16a is dimensionally stable when the insulation space 46a is being filled with foam and the household refrigeration appliance apparatus 10a is in an assembled state. In addition, the machine compartment top wall 16a is designed to be fireproof. In particular, the machine compartment top wall 16a complies with the requirements of the IEC 60335-2-24, particular with respect to fire prevention.

(26) FIG. 7 illustrates schematically a method for assembling a household refrigeration appliance apparatus 12a which has at least one side wall component 14a and at least one machine compartment top wall 16a. The method for assembling the household refrigeration appliance apparatus 12a comprises at least one assembly step 100, 110, 120 and 130 (cf. also FIGS. 8 to 11).

(27) In the assembly step 100, the appliance body 32a is pre-assembled (cf. FIG. 8). In particular, the side walls 30a are moved into a pre-assembly position, wherein the side walls 30a are arranged at an angle with respect to one another. The side wall components 14a are respectively mounted on the side wall 30a. The side wall components 14a are latched with the side wall 30a in each case. The sealing element 18a is pre-assembled. For this purpose, the sealing element 18a, which is designed in the illustrated example as a sealing foam, is injected in an automated manner into the receiving region 22a of the side wall component 14a. In the assembly step 110, the machine compartment top wall 16a is inserted into the pre-assembled appliance body 32a, which is illustrated schematically by the insertion direction 52a (cf. FIG. 9). The machine compartment top wall 16a is placed in the insertion direction 52a on the guiding element 24a.

(28) In the assembly step 120, the side walls 30a are pressed together relative to one another with the result that they are moved into a position in which they are oriented in a parallel manner with respect to one another (cf. FIG. 10). The machine compartment top wall 16a is thus connected to the side wall component 14a, whereby in particular the household refrigeration appliance apparatus is stabilized. In particular, the machine compartment top wall 16a latches with the side wall component 14a. By virtue of the fact that the side walls 30a are pressed together relative to one another, the machine compartment top wall 16a is pressed into the sealing element 18a that is arranged between the machine compartment top wall 16a and the side wall component 14a. This assembly step 120 causes the sealing element 18a to deform in a plastic manner. Consequently, in the assembly step 120a, the region 20a between the side wall component 14a and the machine compartment top wall 16a is filled by means of the sealing element 18a.

(29) In the assembly step 130, the machine compartment top wall 16a is connected to two side walls 30a by means of a deforming process (cf. FIG. 11). The deforming process amounts to pushing through.

(30) In FIG. 12, a further exemplary embodiment of the invention is illustrated. The description below is limited essentially to the differences between the exemplary embodiments, wherein, with regard to like components, features and functions, reference can be made to the description of the exemplary embodiment of FIGS. 1 to 11. In order to differentiate between the exemplary embodiments, the letter a that is attached to the reference character of the exemplary embodiment in the FIGS. 1 to 11 is replaced by the letter b in the case of the reference characters of the exemplary embodiment in FIG. 12. With respect to like-described components, in particular with respect to components having like reference characters, reference can also fundamentally be made to the drawings and/or, the description of the exemplary embodiment of FIGS. 1 to 11.

(31) In the exemplary embodiment illustrated in FIG. 12, a household refrigeration appliance apparatus 12a has a sealing element 18b. The sealing element 18b is designed as a beading, in particular as a rubber beading. The sealing element 18b has a plurality of in particular four sealing lips 50b. The sealing lips 50b are provided so as to fix a machine compartment top wall 16b in addition in side wall components 14b. The sealing element 18b is provided so as to be mounted in at least one assembly step on an edge region of the machine compartment top wall 16b.

(32) When the household refrigeration appliance apparatus 12b is being assembled, the sealing element 18b that is designed as a beading is plugged in one assembly step onto the edge of the machine compartment top wall 16b. In a subsequent assembly step, the machine compartment top wall 16b together with the already pre-assembled sealing element 18b is pushed into the side wall component 14b, in particular into a receiving region 22b of the side wall component 14b. In particular, during a foaming procedure, the sealing lips 50b deform in a plastic manner, whereby, the sealing lips 18b seal a region between the side wall component 14b and the machine compartment top wall 16b.
