Accordingly, the supporting unit is arranged at least partially in the intermediate space and thus a reduced installation space relative to the supporting unit is needed. ## Claims ### Claim 1 A household appliance apparatus, comprising: a housing base unit having a first base portion and at least one second base portion having a planar edge adjoining an underside of said at least one first base portion, said first base portion and said second base portion together defining a lower face of a household appliance, said lower face facing a supporting surface for supporting the apparatus, said at least one second base portion defining a compressor support rail, said first base portion and said at least one second base portion defining an intermediate space therebetween at said planar edge, said intermediate space being an inwardly directed recess extending over an entire width of said housing base unit; and at least one supporting unit for contacting with the supporting surface, the at least one supporting unit disposed at least partially in said intermediate space. ### Claim 2 (depends on 1) The household appliance apparatus according to claim 1, wherein in an installed position said first base portion extends in a first partial region at least substantially parallel to the supporting surface and in a second partial region is oriented at an angle to the supporting surface. ### Claim 3 (depends on 1) The household appliance apparatus according to claim 1, wherein said intermediate space, viewed along its longitudinal extent, has a triangular or quadrangular cross-section. ### Claim 4 (depends on 1) The household appliance apparatus according to claim 1, wherein the at least one supporting unit is in contact with said first base portion. ### Claim 5 (depends on 1) The household appliance apparatus according to claim 1, wherein the at least one supporting unit has at least one screw fastening portion with at least one recess formed therein for receiving a fastening screw. ### Claim 6 (depends on 5) The household appliance apparatus according to claim 5, wherein the at least one supporting unit has at least one form-locking connection fastening portion with at least one form-locking connection element for producing a form-locking connection. ### Claim 7 (depends on 6) The household appliance apparatus according to claim 6, wherein said screw fastening portion and said form-locking connection fastening portion are disposed at an angle to one another. ### Claim 8 (depends on 6) The household appliance apparatus according to claim 6, further comprising at least one backing piece which is in contact with said first base portion on a side remote from the supporting surface. ### Claim 9 (depends on 8) The household appliance apparatus according to claim 8, wherein said backing piece has at least one backing piece recess formed therein for receiving the fastening screw, wherein in a mounted state said recess of said screw fastening portion and said backing piece recess are disposed so as to be aligned with one another. ### Claim 10 (depends on 8) The household appliance apparatus according to claim 8, wherein: said form-locking connection fastening portion has at least one screw recess formed therein for receiving a fixing screw; and said backing piece has a fixing recess formed therein and corresponding to said screw recess for receiving the fixing screw, and in a mounted state said screw recess and said fixing recess are disposed so as to be aligned with one another. ### Claim 11 (depends on 8) The household appliance apparatus according to claim 8, wherein said backing piece has at least one further form-locking connection element corresponding to said form-locking connection element of said supporting unit for producing a form-locking connection. ### Claim 12 (depends on 1) The household appliance apparatus according to claim 1, wherein the at least one supporting unit has at least one roller. ### Claim 13 (depends on 1) The household appliance apparatus according to claim 1, wherein the household appliance apparatus is a household refrigeration appliance apparatus. ### Claim 14 (depends on 1) The household appliance apparatus according to claim 1, further comprising a compressor mounted on said second base portion. ### Claim 15 (depends on 1) A household appliance, comprising: the at least one household appliance apparatus according to claim 1. ### Claim 16 (depends on 1) A method for mounting a household appliance apparatus, which comprises the steps of: providing the apparatus according to claim 1; fastening a backing piece to an inner face of the first base portion; and subsequently connecting the at least one supporting unit to the backing piece on an outer face of the first base portion through the first base portion. ### Claim 17 A household appliance apparatus, comprising: a housing base unit having a first base portion being a sheet metal plate having an exterior side facing a supporting surface, said first base portion and a second base portion together defining a lower face of a household appliance, said lower face facing the supporting surface for supporting the apparatus, said first base portion having a first partial region defining a horizontal portion of said lower face, said first base portion having a second partial region extending upward from said first partial region, said first base portion and said at least one second base portion defining an intermediate space therebetween in at least one region at which said second base portion adjoins said second partial region, said intermediate space extending over an entire width of said housing base unit and being on said exterior side of said first base portion; and at least one supporting unit for contacting with the supporting surface, the at least one supporting unit disposed at least partially in said intermediate space, the at least one supporting unit having a form locking connection fastening portion engaging said first partial region, the at least one supporting unit having a screw fastening portion engaging said second partial region. ### Claim 18 (depends on 17) The household appliance apparatus according to claim 17, wherein said form locking connection fastening portion includes a hook for defining a form-locking connection.
