  • the household appliance also has a machine room.
  • the machine room is formed in the outer case.
  • the outer housing has a rear wall part.
  • the household appliance has a machine room rear wall. This is in particular separate from the rear wall part. Viewed in the depth direction of the household appliance, the machine room is covered towards the rear by the machine room rear wall.
  • a second aspect of the invention relates to a method for assembling a machine room rear wall.
  • a machine room is formed in a rear lower area of a housing.
  • Components of a refrigeration circuit of the household refrigeration appliance can be arranged in such a machine room.
  • a compressor can be arranged therein.
  • the machine room is separated from a storage room for food in the household refrigeration appliance.
  • a storage space for food can be a refrigerated compartment or a freezer compartment, for example.
  • the inner container delimits the accommodation space for food with walls.
  • Such a machine room is therefore also arranged outside of an inner container of the household refrigeration appliance.
  • the inner container is housed in the outer case.
  • An intermediate space is formed between the inner container and the outer housing and is filled with thermally insulating material.
  • the machine room is also arranged in particular outside of this intermediate space, so that at least the thermally insulating material is arranged between the machine room and the inner container.
  • such a machine room is also limited by walls. These can be opposite machine room side walls in the width direction.
  • a machine room front wall can be provided, which delimits the machine room towards the front when viewed in the depth direction is.
  • the machine room is also usually delimited at the top by a machine room ceiling wall.
  • a machine room rear wall which delimits the machine room to the rear in the depth direction, is usually fastened to a support structure with more than three screw connections.
  • a multiple screw connection means a lot of work and thus a corresponding amount of time in production.
  • One aspect of the invention relates to a household appliance with an outer housing.
  • the household appliance also has a machine room. This is intended to be components or
  • the machine room is intended to accommodate functional units of a refrigeration cycle of the household refrigeration appliance.
  • a compressor of a refrigeration circuit can be a corresponding functional unit here.
  • other functional units of such a household refrigeration appliance can also be arranged in the machine room.
  • the outer housing has a rear wall part. This means that it is a rear or rear part viewed in the depth direction of the household appliance.
  • the household appliance also has a machine room rear wall. This is in particular a separate component to the rear wall part. Through the machine room rear wall, the machine room is in the depth direction of the home appliance viewed backwards covered.
  • the machine room rear wall has a coupling area.
  • the machine room rear wall is coupled to the rear wall part with this coupling area. Viewed in the vertical direction of the household appliance, the coupling area is arranged so that it overlaps with the rear wall part. Viewed in the depth direction of the household appliance, the coupling area is formed or arranged on both sides of the rear wall part.
  • This configuration of the coupling area also has the particularly advantageous effect that undesired relative movements between the rear wall part and the rear wall of the machine room are prevented, particularly at least in the depth direction of the household appliance. It is precisely at this interface that undesired deflections of the mutually facing edge regions of the rear wall part on the one hand and the rear wall of the machine room on the other hand can be avoided.
  • the coupling area encloses a lower edge area of the rear wall part on both sides in the depth direction, in particular in the width direction at least in sections.
  • the coupling area forms a support structure on both sides, in particular in the depth direction, in which the lower edge area of the rear wall part is accommodated.
  • the coupling region has walls that cantilever upwards and extend in the width direction with their longitudinal axes. In particular, they are formed as plate-like strips or webs. They can also be referred to as coupling straps. Due to these walls, the coupling area is also open at the top. In particular, the coupling area can be arranged lying on both sides of the rear wall part in this depth direction.
  • the coupling area is formed on an upper edge area of the rear wall of the machine room, viewed in the vertical direction.
  • the coupling area therefore represents the upper closing area of this machine room rear wall. In this regard, it is therefore designed to be exposed on this upper edge area.
  • the coupling area is also freely cantilevered towards the top. This enables very simple handling and coupling to the rear wall part.
  • the coupling area is formed in one piece with the rear wall of the machine room.
  • a component-minimised concept is achieved with regard to the rear wall of the machine room and the coupling area.
  • Undesirable positional tolerances can therefore also be avoided for the coupling area.
  • Last but not least, a stable configuration of both the coupling area and the rear wall of the machine room is also made possible. In particular, it can also be achieved that the upper area of this machine room rear wall is stabilized or stiffened.
  • the coupling area is a bending area of the rear wall of the machine room that is produced by forming. This means that the coupling area can also be easily generated during the manufacture of the rear wall of the machine room itself. As a result, this coupling area can also be designed very precisely and individually. A high degree of dimensional accuracy is also made possible as a result.
  • the machine room rear wall is made of sheet metal. On the one hand, it is therefore stable and particularly suitable for being able to reliably meet the fire protection requirements of the household appliance. Last but not least, in such an embodiment, in which the coupling area is produced by forming and is a bending area, production is relatively easy.
  • the coupling area has a gripping geometry that is open toward the top. With this gripping geometry, a lower edge area of the rear wall part is gripped in the final assembled state. This enables a stable coupling interface between the upper edge area of the rear wall of the machine room and the lower edge area of the rear wall part. Through this Gripping geometry enables stable coupling on the one hand and secure positioning of the components mentioned to one another on the other hand.
  • the gripping geometry can be a groove-like receptacle. In this regard, it can also be referred to as a slot-like receptacle. A U-like shape of this receptacle, which forms the gripping geometry, is also possible in this respect. This is formed when viewing the coupling portion in a direction of its longitudinal axis. The longitudinal axis is oriented in particular in the width direction of the household appliance.
  • the gripping geometry is formed with regard to a U-shaped configuration such that viewed in the width direction of the household appliance, only one U leg is formed in each case over partial lengths of the gripping geometry. In particular, this is formed on at least some partial sections of this length of the encompassing geometry measured in the width direction. This also means that the gripping geometry is not designed as a complete U at every point over its entire length measured in the width direction in cross section. In particular, it is provided that in this longitudinal direction of the encompassing geometry, which extends in the width direction of the household appliance, the cross-sectional shape of this encompassing geometry is predominantly only a partial U, in particular at all points along this length.
  • this also means that the gripping geometry, viewed along its longitudinal axis, has a number of points at which the change between a front U half and a rear U half is formed, but a complete U is not formed at these points.
  • a complete U is not formed at any point in the cross section of this encompassing geometry.
  • the coupling area can be designed as an insertion area for the lower edge area of the rear wall part.
  • the lower edge area can be inserted into this from above.
  • only one plug-in connection is then formed, but it can also be provided that the coupling area is formed as a snap-in area.
  • the lower edge area can then be inserted into these and also snapped into place.
  • the gripping geometry has a number of coupling straps. These are arranged on an upper edge area of the rear wall of the machine room. In one exemplary embodiment, these coupling straps are strip-shaped webs. They are oriented upwards. In particular, they are designed so that they cantilever upwards.
  • a coupling strap can be single-walled. However, it can be at least double-walled, at least in some areas. This can be the case, for example, when a coupling strap is shaped by a bending process.
  • the relevant double wall can be designed in such a way that the two wall layers are in direct contact with one another, in particular over their entire surface.
  • the coupling straps are offset from one another in the depth direction.
  • at least one coupling strap is arranged in front of the rear wall part, viewed in the depth direction, and at least one further coupling strap is arranged behind the rear wall part, viewed in the depth direction.
  • the coupling straps are positioned alternately with respect to one another in terms of their position in the depth direction, viewed in the longitudinal direction of the gripping geometry. This means that a respective alternating change is formed between a front coupling strap viewed in the depth direction and a rear coupling strap.
  • the coupling straps can be arranged in contact at least in regions on a front side and/or on a rear side of the rear wall part. This enables the interface to be supported and achieves a more stable fit of the lower edge area of the rear wall part in the coupling area.
  • the coupling straps are arranged without overlapping one another in the width direction and thus in the longitudinal direction of the gripping geometry. In this regard, however, they are arranged directly adjacent to one another in one exemplary embodiment. This means that the coupling straps are arranged in a row relative to one another in the width direction. However, the offset in the depth direction is formed alternately in this regard. As a result, a particularly advantageous coupling area can be formed. On the one hand, this enables a simple and stable coupling to the rear wall part, and on the other hand, a particularly stable mounting is achieved in a mounted end position at this interface between the rear wall part and the rear wall of the machine room.
  • the fastening geometry or the gripping geometry has three separate coupling straps.
  • the coupling straps arranged in a row relative to one another in the width direction have a central coupling strap.
  • this central coupling strap is the coupling strap that is arranged behind the rear wall part.
  • the other two coupling straps are arranged in front of the rear wall part, viewed in the depth direction.
  • the rear wall part is arranged so that it freely cantilevers downwards and thus viewed in the height direction downwards.
  • the rear wall part is designed with a drip edge.
  • Any condensate that may have formed can drip down in a defined manner on such a drip edge.
  • the drip edge prevents liquid from dripping from the rear wall into the machine room and coming into contact with electrical components here. Without the drip edge, the liquid could flow along a simple bend radius and thus into the reach the engine room. The liquid is directed to the rear wall of the machine room via the drip edge.
  • the rear wall of the machine room is screwed to a support structure of the household appliance with screw connections in a lower area viewed in the height direction of the household appliance, in particular in the lower corner areas.
  • screw connections are only provided at these lower corner regions.
  • only one screw connection is provided at each corner area.
  • only two screw connections are provided in one exemplary embodiment, in order to additionally fasten the rear wall of the machine room. As a result, the assembly effort is reduced accordingly.
  • the rear wall of the machine room has at least one passage for a wall spacer of the household appliance.
  • the bushing is a continuous hole in the rear wall of the machine room. If a household appliance therefore has at least one such wall spacer, it can then also be arranged on both sides of the rear wall of the machine room, since it can extend through this bushing.
  • Such a passage in the rear wall of the machine room simplifies the assembly scenario if the household appliance is to have at least one such wall spacer.
  • a wall spacer represents a local component of the household appliance that protrudes in a specific spatial direction. This means that the wall spacer is the component of the household appliance that protrudes the furthest in this direction.
  • a defined distance from the wall between the household appliance and a wall on which the household appliance is to be set up as closely adjacent to it as possible can be set in a defined manner. Because the household appliance can then be positioned relative to the wall in such a way that the wall spacer is present on this wall and the rest of the household appliance is then positioned at the desired small distance from this wall and in this respect then without contact with the wall.
  • Such a passage also makes it possible for a wall spacer to be mounted on a support structure of the household appliance in one exemplary embodiment and for the machine room rear wall to be arranged only subsequently. By carrying out it is then also possible that the Machine room rear wall can be brought over the already mounted wall spacer and mounted in its final position.
  • the household appliance has at least one such wall spacer.
  • the leadthrough has a contoured edge, at which contact is made with the wall spacer passed through the leadthrough.
  • the contour edge can also be referred to as a contact edge or boundary edge.
  • the machine room rear wall can thereby be suspended from the wall spacer. A further advantageous coupling principle can thereby be made possible. This further improves the positioning of the rear wall of the machine room. Since a wall spacer is a stable and robust component in itself, the forces that are exerted on the wall spacer by hanging up the rear wall of the machine room can be absorbed without any problems.
  • the wall spacer is arranged in the bushing in an overlapping manner, viewed in the width direction of the household appliance. This enables a further securing of the position of the rear wall of the machine room. In particular, a corresponding removal protection is thus formed in the depth direction.
  • a further aspect of the invention relates to a method for assembling a machine room rear wall of a household appliance. This method preferably has the following steps:
  • Edge area is formed towards a support structure of the household appliance, so that a lower edge portion of the machine room rear wall is moved to the support structure out until the end position of the machine room rear wall is set.
  • the rear wall of the machine room which is then in particular vertically positioned, is additionally fastened after the pivoting by at least one screw connection, in particular at least two, in particular only two, screw connections.
  • these screw connections can be produced on the lower corner areas of the rear wall of the machine room, which are opposite in the width direction.
  • a screw connection to the support structure is provided in this regard.
  • At least one wall spacer of the household appliance is attached to a component, in particular the support structure, of the household appliance before the rear wall of the machine room is installed.
  • the assembly scenario for the rear wall of the engine room is then completed as explained above.
  • the rear wall of the machine room preferably has a passage through which the wall spacer is passed when the rear wall of the machine room is pivoted toward the support structure.
  • the rear wall of the machine room it is possible for the rear wall of the machine room to be seated on the wall spacer from above with an upper coupling edge of the bushing and therefore to be suspended from the wall spacer in this respect.
  • the rear wall of the machine room is moved in the width direction and/or in the height direction. This moves the machine room rear wall behind an undercut of the wall spacer.
  • Overlap in at least one spatial direction of the wall spacers also serves as a removal safeguard for the machine room rear wall.
  • Advantageous exemplary embodiments of the domestic appliance are to be regarded as advantageous exemplary embodiments of the method, with the components enabling the assembly steps alone or at least partially in interaction and/or enabling minimum distances to be set.
