Definitions

• the invention relates to a household refrigerator with at least one machine room for accommodating one or more units involved in the cooling capability of the household refrigerating appliance according to the preamble of claim 1.
• the invention is based on the problem of achieving a simplification of assembly.
• the mounting of the securing retaining strip can be done in an advantageous manner by simple pressure movements. So it can very easily a desired position of the respective position to be secured aggregate, which automatically secures the correct adjustment, in particular be enabled by the holding web is inserted into the recess, for example, up to a stop, and subsequently the retaining strip to this connection in a horizontal plane is pivoted, so that it is locked without further alignment measures the retaining strip on the Rastanformung.
• a Rastanformung be optically unobtrusive and mechanically advantageous associated with the bottom of the machine room, for example, lie on a lateral end of this floor and thus secure a lateral end of the retaining strip.
• the Rastanformung extends from the ground pointing downwards and thus allows the formation of a retaining abutment for the at least one base in the upper part holding bar.
• a stable mechanical support is advantageously ensured if the Rastanformung viewed in plan view is formed in particular rectangular. For this purpose, it may preferably occupy, for example, an area of at least five square centimeters.
• this surface takes the form of a rectangle lying approximately parallel to the housing outer edge of the machine room in order to prevent the extract of the retaining strip over the extension of the longitudinal edges can. In general terms, this Rastanformung thus forms a crossbar against a horizontal extension or movement direction of the position to be secured aggregate.
• the retaining strip itself may be metallic, for example as a steel profile, formed according to an expedient development of the invention for a high mechanical stability, and still allow the bottom itself is formed of weight-saving plastic. For a high stability, this may advantageously be reinforced constructively, in particular by the formation of ribs or the like.
• the intervening bearings can be forcefully clamped in their rubber-like design interpretation and thus provide the necessary restoring force to securely hold the retaining strip on the housing, especially at the bottom of the engine room.
• a particularly simple construction provides according to a further advantageous embodiment of the invention, that several, in particular four bearing points for a Aggregate, for example, a compressor, are provided, of which a first group of several with respect to the housing inwardly located bearings, in particular two with respect to the housing inwardly located bearings in shoe-shaped receptacles of the bottom against a pull-out or lifting movement and a second group of several outwardly located bearings, in particular two outwardly located bearings, are secured by the retaining bar against a pull-out or lifting movement.
• the backup in the inner shoe-shaped receptacles is then carried out in an advantageous manner solely by pushing the unit, without it being necessary to provide further securing means.
• the outer bearings then hold in an advantageous manner the feet of the unit located thereon also without further securing means alone by clamping the retaining strip.
• the retaining strip thus acts as a crossbar or securing bracket, which has at least one locking element for locking with a corresponding counter element on the housing.

• the household refrigerating appliance HK shown in FIG. 1 has a housing G which, for example, comprises a space for cooling and a freezer compartment. These can be closed by a common door or - as here - by several doors. Also, more cold rooms or the formation of only a refrigerator or freezer is possible. The household refrigerator can thus also be a pure freezer. In the lower area and at the back is the housing G with a machine room MR to

• the unit AG can be supported on a floor B of the machine room MR.
• the unit AG on two laterally mounted feet SF, which are advantageously held on one or more vibration dampers VD. These serve as bearings LS for supporting the unit AG with respect to the ground B.
• the feet SF of the compressor are designed as flanges of the unit, in particular the compressor, extending laterally in the depth direction of the machine space, or welded to the housing ,
• a retaining strip HL is provided to secure the unit AG, at least a part of the bearings LS overlaps with the upstanding feet SF with an overlapping part OF and at the same time engages under the bottom B of the engine room MR with a lower grasping part UF, so that the located between the lower grasping part UF and the overlapping portion OF bearings LS are subjected to force and by their elasticity exercise a vertical force such that the feet of the unit AG are pressed firmly from below against the retaining strip.
• each bearing point LS are provided with vibration dampers VD for the unit AG by way of example.
• two are with respect to the housing G inwardly, on both sides the aggregate AG arranged bearings LSe inserted into shoe-shaped receptacles A of the engine room MR, so that they are secured there against a lifting movement upwards.
• the unit AG is further on two outward, especially at the rear edge, located on both sides of the unit bearings LSa by the retaining strip HL against secured a pull-out or lifting movement.
• the inner bearings LSe are thus secured solely by inserting the compressor without further assembly steps.
• the shoe-shaped receptacles A can be formed as an integral part of a one-piece engine room, for example an injection-molded part.
• the aggregate AG on the retaining strip HL to be attached is securable.
• the retaining strip HL is fastened to the housing G so that it can not be screwed or positively locked, in which case the machine room MR, irrespective of its concrete design, is considered part of the housing.
• the retaining strip HL is dimensionally stable in itself and, for example, metallic and folded several times around a longitudinal edge in an approximately C-shaped or U-shaped profile cross-sectional shape.
• an upper flange or leg is formed as an overlapping part OF, which overlaps in the mounted position, the bearings LS and the feet SF, whereas a lower flange engages under the bottom B of the engine room MR as the lower grip part UF.

• the retaining strip HL then sits automatically in a positive, permanent securing position without the need for a screw connection. It forms a Gartial. Locking bracket for the unit against its possible movement in the horizontal and / or vertical direction.
• the Rastanformung RA is assigned to the bottom B of the engine room MR at a location spaced from the abutment W point. It is preferably in the lateral direction, i. over the clear width or width of the machine room offset from the abutment W, in particular in the region of the abutment opposite end portion of the retaining strip HL.
