Definitions

• the invention relates to a refrigeration appliance, in particular domestic refrigeration appliance, with a housing which encloses a heat-insulated receiving space for refrigerated goods, wherein at least one condenser is arranged on a rear side of the housing, according to the preamble of
• Tolerance compensation usually pass vertically extended condenser slots. Due to manufacturing tolerances, the bottom edge of the condenser is often not fixed in the gutter, but is raised against the floor a bit, which can lead to disturbing noise, because the condenser to operate
• Vibrations is stimulated. This is perceived by the customer as disturbing, so that frequent costly customer service calls result, in which then only the condenser is pushed back down into the gutter. The cost of these "repairs" is therefore unreasonably high.

• the invention solves this problem by a refrigeration device having the features of claim 1.
• a refrigeration device Under a refrigeration device is in particular a household refrigeration appliance understood, ie a refrigeration appliance for household management in households or possibly in the Catering area is used, and in particular serves to store food and / or drinks in household quantities at certain temperatures, such as a refrigerator, a freezer, a fridge-freezer or a wine storage cabinet.
• a refrigeration appliance in particular domestic refrigeration appliance, with a housing which encloses a heat-insulated receiving space for refrigerated goods, wherein at least one condenser is arranged on a rear side of the housing, the condenser is mounted on the housing in at least one clamping receptacle fixed to the housing.

• Condenser form With the invention, a refrigeration device is provided which allows a permanently stable and vibration-damping mounting of the condenser, without increasing the assembly costs.
• the condenser has an upper horizontal edge region, a lower horizontal edge region and two lateral vertical edge regions.
• the condenser is held with at least one of these edge regions in the clamping receptacle.
• the clamping receptacle clamps the edge region in the horizontal direction and not in a possibly vertical pulling direction.
• a particularly high level of security against pulling out of the condenser from the holder is advantageously made possible by the fact that the clamping receptacle has a retainer engaging in the condenser, which counteracts the captured edge area
• This retainer can be divided in several ways and thereby intervene in several interstices of the net-like condenser within the outer edge region. For example, securing the lower edge portion in the clamp bracket and attaching (eg, riveting) the upper edge portion to the housing effectively prevents the condenser from lifting upwardly when lifting the unit at the condenser by virtue of the retainer blocking or even blocking the movement. Even if the device is lifted on the condenser, it remains firmly secured in the clamp receptacle.
• the clamping receptacle is not only formed itself as an injection molded part and, for example screwed to the rear wall of the housing, but forms an integrally molded attachment of a larger unit,
• a machine room located in the lower rear area which can be formed overall as an injection unit together with the sprayed-on at its upper end clamping bracket.

• the abutment can also apply a clamping force enhancing press force in the horizontal direction to the condenser and at the same time damp its vibration relative to the housing.
• a torque occurring on the condenser due to the offset in height of the abutment and the abutment can be counteracted by firmly securing it to the housing, in particular by riveting or screwing it at its edge region opposite the at least one clamping holder. Furthermore, it is favorable to provide only one clamping holder which acts centrally on the respective edge region, so that a three-point mounting is achieved with two fastenings of the opposite edge region, which is particularly insensitive to

• the refrigeration appliance HK shown in FIG. 1 is a household refrigerating appliance and may be a pure refrigerator or a pure freezer or a combination thereof. It has a housing G which, by way of example only, comprises exactly two receiving spaces AR for refrigerated goods, which are closable on the front side of doors T in each case. At least one condenser V, which covers a total of a partial area F of the rear side R, is arranged on the rear side R of the refrigeration device HK. The condenser V is located on the outside of the housing G and is thus in thermal contact with the ambient air.
• the condenser V comprises a conduit RL for coolant contained therein, which is here formed by way of example in horizontal meanders. This is not mandatory. Between the meanders of the pipeline RL are connecting webs VS, over which the meanders of the
• Piping RL stabilizing connected to each other. These connecting webs VS are designed here as the pipe RL on both sides enclosing double webs. Overall, the here a condenser V covers a rectangular area F, which is bounded by an upper and a lower transverse edge region OR, UR and two laterally projecting edge regions, a left edge LR and a right edge RR.
• At least one edge region of the condenser V is held in at least one clamping receptacle K fixed relative to the housing G.
• the lower edge region UR is held in the clamping receptacle (s) K.
• two lateral clamping receptacles K may be provided.
• exactly one transverse mount K is provided, so that a three-point mount for the condenser V results with two rivets or similar fastenings N at the top.
• the lower edge region UR is clamped in such a way that the force direction of the clamp acts with a component in the horizontal direction and surrounds the lower edge region UR between a stop A and an opposite abutment WL.
• this has a stop A secured to the lower edge region UR of the liquefier V away from the rear wall R of the refrigeration device HK and an abutment WL securing the edge region UR against movement towards the rear wall R.
• the abutment WL is offset from the stop A in the direction of the center of the surface F occupied by the condenser V, here So up. This would result in a tilting tendency of the condenser V to the rear without further action, but counteract the upper fasteners N of the upper edge of the condenser OR OR V.
• the determination of the upper edge OR therefore supports the frictionally tight clamping clamping for the lower edge region UR, so that this is analyst limbal halterbar.
• the clamping receptacle K has a retainer RH engaging in the condenser, which can be engaged behind by the edge region UR of the condenser, that is to say can not be grasped here.
• This underreaching happens here latching, since the retainer RH has on its underside a locking projection RV, so as to achieve during assembly a correctness of the mounting confirming clacking noise.
• the retainer RH has a nose-like overall shape in side view so as not to present an obstacle to the condenser during assembly.
• the retainer RH is divided into itself several times vertically and shows several gaps between its projecting tines. While the projecting prongs engage in a plurality of interstices of the net-like condenser within the area F bounded by the outer, here lower, edge area UR, the connecting webs VS can thereby engage in the gaps. Thus, a backup against lateral movement is achieved.
• the condenser V is first inserted obliquely from above in the direction of the rear wall R in such a way that it communicates with the lower edge UR on the
• the condenser V is pivoted about the abutment WL as the first pivot point 1 and the upper approach of the retainer RH as a second pivot point 2 in the direction of arrow 3 by a few to a few degrees, so that it in the shown in Figure 6 reaches vertical end position and thereby engages latching with its lowest pipe RL behind the locking projection RV and thus is kept aligned in the vertical direction.

• the abutment WL can have an increased elastic deformability compared with the stop A, for example by comparatively thin blade tips (FIG. 7) forming the abutment WL.
• the at least one clamping bracket K opposite edge region is firmly secured to the housing G, in particular riveted or screwed with this, so that the condenser V immovable and without the possibility of relative movement, cause the noise could, is held in the terminal receptacle K.
• the condenser V is held by two laterally outer rivets N, so that with the one lower clamping bracket K total results in the said three-point bearing.
• the clamping receptacle K can be formed overall as a one-piece injection-molded part and can thereby comprise the stop A and here two abutments WL integrally in one component.
• the unit shown there may also be formed as an integrally molded attachment of a larger unit and thus need no separate attachment.
