Service, maintenance and repair works on the home appliance device, preferably on the divisional wall and in particular on components cooperating with the divisional wall section, can in particular be performed advantageously easily, preferably due to the segmentation of the divisional wall into the first wall section and the second wall section.

In this context, "configured" is in particular to mean specifically programmed, designed and/or equipped. By an object being configured for a certain function is in particular to be understood that the object implements and/or fulfills said certain function in at least one application state and/or operating state. By a "home appliance device" is in particular to be understood at least a portion, preferably a sub-assembly group, of a home appliance. The home appliance is in particular provided for storing and preferably tempering victuals such as beverages, meat, fish, vegetables, fruits, milk and/or dairy products in at least one operating state, advantageously for the purpose of enhancing a keepability of the stored victuals. Advantageously, the home appliance is embodied as a home chiller appliance, which is in at least one operating state configured for cooling victuals. The home chiller appliance could in particular be embodied as a climate cabinet, an ice-box, a refrigerator, a freezer, a refrigerator-freezer combination and/or a wine cooler. However, the home appliance could also be embodied as a home appliance for warming up and in particular for cooking victuals, e.g. an oven, a steamer and/or a microwave.

In this context, a "machine compartment" is in particular to be understood as a compartment which is delimited from at least three, preferable at least four and advantageously from at least five sides, and which is in particular configured for accommodating further units of the home appliance device, such as a refrigerant cycle. The machine compartment is in particular different from a storage compartment of the home appliance device, which is configured for storing victuals. The machine compartment comprises in particular two lateral wall sections, a rear wall section, a bottom wall section and/or a front wall section. The two lateral wall sections, the rear wall section, the bottom wall section and the front wall section in particular delimit the machine compartment from five sides. The machine compartment may be delimited from a sixth side in particular by the storage compartment.

In this context, a "divisional wall section" is in particular to be understood as a wall section which is configured for dividing the machine compartment into at least two sub- compartments, preferably at least into a first sub-compartment and a second sub- compartment. Preferably, the home appliance device may comprise at least one further divisional wall section and advantageously at least two further divisional wall sections, in particular a second divisional wall section and preferably a third divisional wall section, which are in particular respectively configured for dividing the machine compartment in further sub-compartments. In particular, the second divisional wall section is configured for dividing the machine compartment into the second sub-compartment and a third sub- compartment. Advantageously the third divisional wall section may be configured for dividing the machine compartment into the third and a fourth sub-compartment. The further divisional wall section may in particular be implemented at least substantially equivalent to the divisional wall section. By the term "implemented at least substantially equivalent" is to be understood, in this context, in particular identical, preferably excepting for manufacturing variances and tolerances. Advantageously, the further divisional wall sections are at least partly implemented different from the divisional wall section. The further divisional wall sections may in particular differ from the divisional wall section by at least one of the features below. The divisional wall section extends in particular from the rear wall section up to the front wall section of the machine compartment. In particular the second wall section extends to the rear wall section. Preferably the first wall section extends to the front wall section. Alternatively or additionally the divisional wall section may comprise further wall sections apart from the first and the second wall sections. In particular the divisional wall section may be located centrally with respect to the machine compartment and may preferably divide the machine compartment equally into the first sub-compartment and the second sub-compartment.

In particular in an installation position a main extension plane of the divisional wall section is at least substantially parallel to a main extension plane of the lateral wall section and/or at least substantially perpendicular to a main extension plane of the rear wall sections and/or the front wall section of the machine compartment. A "main extension plane" of an object is, in particular, to be understood as a plane extending parallel to a largest side of an imaginary rectangular cuboid which only just entirely encloses the object and preferably extends through a geometric center of the object.

Advantageously, "implemented integrally" could in particular mean made of one piece. "Made of one piece" is, in particular, to mean, in this context, manufactured from one single piece, e.g. by production from one single cast and/or by manufacturing in a one-component or multi-component injection-molding process, and advantageously from a single blank. The term „at least mostly" with reference to an object is in particular to mean more than 50 %, preferably more than 70 %, and advantageously more than 90 % of a volume, in particular an enclosed volume, and/or of a mass of the object. Furthermore, it is proposed that the guiding unit is configured for guiding the first wall section at least substantially parallel to the second wall section.
