This usually comprises a refrigerant compressor, which is connected to a condenser, wherein the refrigerant compressor or compressor is arranged in a machine room. The engine room is usually formed in a lower rear portion of the household refrigerator.

For evaporation outside the cooling range of the household refrigerator, it is known to collect the defrost water and to use the waste heat of the existing compressor for evaporation. For this purpose, the defrosting water is collected in a collecting container arranged above the compressor, which is also arranged in the machine room. By the waste heat of the compressor or refrigerant compressor, the defrost water is heated, thus accelerating evaporation.

From the DE 10 2011 006 606 A1 is such a configuration known. There is also provided that arranged in an upper region of the refrigerant compressor collecting tray for receiving and evaporation of defrost water has a defined overflow. Overflowing water is then drained from the collecting tray into an additional tray positioned below the refrigerant compressor, so that a larger collecting volume is provided here.

It is an object of the present invention to simplify the installation of components in the machine room with respect to the assembly work and yet to ensure a reliable and secure mounting.

This object is achieved by a household refrigerator, which has the features of claim 1.

An inventive household refrigerator comprises a housing in which an inner container is arranged. The inner container defines an interior for receiving food. In addition, the household refrigerating appliance comprises a machine room separated from the interior, in which at least components of a refrigeration cycle of the household refrigerating appliance are arranged. An essential idea of the invention is to be seen in that in the machine room, a carrier shell is arranged, on which at least one further component by at least one snap connection and / or at least one connector and / or at least one latching connection is held connecting, in which case the connecting bracket beyond zusatzbefestigungselementlos is formed. It is thereby realized an embodiment in which an attachment of another component on such a carrier shell is formed by one or more snap connections and / or by one or more connectors and / or by one or more latching connections, wherein, however, no further additional separate Fasteners are then needed and available. The attachment is thus in each case in particular only via at least one snap connection and / or only at least via a plug connection and / or via only at least one latching connection and, moreover, without any additional additional separate fastening elements.

As a result, the assembly cost is significantly reduced and thus reduces the number of components. An assembly and disassembly can be done faster and yet an at least stable stable mechanical support of the component to the carrier shell can be achieved and made possible.

The carrier shell has a bottom, in which at least one latching receptacle is designed for a latching connection. Just such a ground-integrated locking receptacle allows fast and easy mounting of the other component. Purely by the then occurring weight of the other component, the latching connection then generated is held positively supportive.

It is envisaged that the carrier shell has at upper edge sides of side walls in cross-section C-shaped grooves, in which interruptions are formed for plug connections. These side walls are in particular longitudinal side walls. By such a specific shaping of the upper edge sides, the carrier shell is highly stable and also very rigid. As a result, it already serves in this context at these points particularly preferably the mechanical coupling with another component. By practically interruptions are formed in these grooves, corresponding cover elements can extend into it and are thus kept permanently stable. The connector is particularly advantageous at such a locally specified location and thus in the upper region of the carrier shell on such a specified edge side profile. On the one hand, this also improves the accessibility for a fitter, on the other hand, the laterally acting fixation achieved. Interruptions are thus preferably slots in these longitudinal side walls, in which plug-in elements of the further component can be inserted oriented preferably oriented perpendicular to a longitudinal axis of the carrier shell. As a result, in addition to a lateral securing also in the vertical direction also advantageous axial securing and thus a backup in the direction of the longitudinal axis of the carrier shell is achieved.

It is envisaged that a first component with a first type of connection, in particular a latching connection, is fastened to a bottom of the carrier shell, and is connected to a longitudinal side wall of the carrier shell by a second type of connection, in particular a plug connection. This is an advantageous embodiment in particular, when the carrier shell is formed smaller in a direction perpendicular to the longitudinal axis and thus in a direction extending between the upper edge sides, than such a distance between the two edge sides. Thus, it is further provided that in the state connected to the carrier shell, the first component has an extent in the direction perpendicular to a longitudinal axis of the carrier shell, which is smaller than a distance between two longitudinal sides in the carrier shell. As a result, such a further dimensioned component undergoes a secure attachment to the carrier shell.

It is preferably provided that the component has a connection to the carrier shell at least at two points. As a result, the mechanically stable support and position fixation on the carrier shell is favored again. In this context, at least two separate mechanical connections can be provided on the upper edge sides, in particular with respect to the longitudinal axis of the carrier shell opposite parallel upper edge sides. Likewise, on the one hand, a mechanical coupling of the further component with the carrier shell may be provided on such an upper edge side on the one hand and on the bottom of the carrier shell on the other hand. This makes it possible to realize a wide variety of connection concepts, so that also differently dimensioned and designed further components individually to their size and / or their weight and / or their shape adapted best possible locking and anchorage in the carrier shell experienced.

It is preferably provided that the further component has a connection to the carrier shell at least at two points, for which purpose the already achievable advantages have been mentioned above.

It is preferably provided that a first component is an operating capacitor housing, which thus receives a capacitor of the refrigeration cycle of the household refrigerating appliance. The housing thus constitutes a unit for receiving this capacitor.

Preferably, it is provided that a second component with a first type of connection, which is preferably a snap connection, on a first longitudinal side wall of Carrier shell is attached, and with a second connection, which is preferably a connector, is connected to a second longitudinal side wall of the carrier shell. The snap connection and the plug connection represent different types of connection. In particular, it is provided that a snap element is arranged such that a snap element is movably arranged on a further component attachable to the carrier shell, in particular can be rotated and pivoted about an axis of rotation. By means of such a rotational movement then to be achieved, a snap-in into a snap-on receptacle on the carrier shell is achieved.

A connector is defined in particular by the fact that a plug-in element is inserted into a plug-in receptacle, but not latched or snapped therein, but only by this nesting and nesting a holder is reached.

On the other hand, a latching connection is defined in such a way that, when the latching element and a latching receptacle are brought into one another between the carrier shell and the further component, a holder is produced by a rear engagement and / or a rear hook of some kind.

It is preferably provided that a component to be fastened to the carrier shell is connected to the carrier shell by means of a snap connection, wherein it has a pivotable snap element which is formed in a channel C-shaped groove formed on an upper edge side of the longitudinal side wall of the carrier shell. engages and thus snapped into the cavity formed by the C-shape. As a result, the snap element is anchored particularly well, since due to the C-shape and a certain flexibility of this groove deformation is achieved and thus a certain positive engagement of the snap element is made possible in this C-shape, which is then formed in cross section to the effect that even then the snap element is embraced in a manner engaging in the channel area by this C-shape of the channel like a clamp.

It is preferably provided that a snap element integrally has at least one plug-in element for a plug connection. In such a configuration is then in integrated dual form both a snap connection and a Plug connection available and thus for individual components a particularly reliable connection and support allows, however, can also be set very easy to install or solved.

It is preferably provided that a second component is a water stop unit or a collecting and evaporation tray for defrost water or an electronic unit or a compressor of a refrigeration cycle of the household refrigerating appliance.

Due to the proposed concept of the mechanical connection of other components to such a carrier shell in the engine room of the household refrigerator both very large components and smaller components can be held reliably and positionally secure by a simple and quick installation.

Preferably, a 180 ° bend of the carrier shell is used for large components front and rear, which is formed in particular on the upper edge sides and is formed by the preferably C-shape. The cavity or intermediate space of this bend is preferably used as an insertion possibility for feet of the housing to be installed of the components. The position is thus given vertically and horizontally and also in the direction forwards and backwards. Essential are recesses with interruptions at these C-shaped edge sides of the carrier shell, because then vertical ribs on the feet of the components to be mounted can dive therein. As a result, it defines the installation position in a self-centering manner during assembly, and the correct orientation of the component to be mounted in the carrier shell is also achieved independently. For it is preferably also provided that the possible connections are designed so that in each case a very specific position for a component to be mounted can be provided, so that only a clear assembly is possible here. A wrong orientation or a positionally wrong arrangement of a component on the carrier shell is prevented, so that preferably by the possible connections, a kind of mounting coding is formed.

These recesses or interruptions are preferably positionally arranged so that several components, depending on the use, can be mounted. A front foot of a component is preferably movable in an advantageous embodiment and mounted on a rotational axis in the male housing, thereby in particular a snap element, as defined above, is formed.

In an electronics housing or an electronic unit which is to be mounted as a component on the carrier shell, or an evaporation tray is provided with such a foot in its mounting position, a snap connection.

It is also further provided that the housing of these components can then be assembled by the spreading apart of the front and rear feet between the front and rear 180 ° bend or C-shape of the carrier shell.

The preferred type of positive engagement and also the force fit depends on the requirements of the embodiments. It may also be provided that in the case of an electronics unit and / or an evaporation tray, further safety for dismantling a snap connection with a tool, for example a screwdriver, must be unlocked. It may be provided that in a water stop unit for disassembly and release of a connection is provided with such a screwdriver.

In the case of small components, such as an operating capacitor mentioned by way of example, in particular only one of these specifically shaped edge sides of the carrier shell is used for mechanical coupling. Interruptions at this bend or C-shaped configuration of the upper edge side are also here then preferably as an insertion possibility for a lower foot or a plug-in element of the housing to be installed. This determines the position of the rear area of this housing vertically and horizontally in the backward direction. Here, too, preferably defines a vertical rib at a housing foot the installation position by immersion in the recess in the support rail, in particular in a locking receptacle in a floor, and fixes the horizontal position in the left and right direction with respect to the two sides opposite a longitudinal axis of the support tray.

A front foot of this housing is preferably designed as a box-like element in an insertion bevel. This makes the threading in a counter-receptacle improved and the assembly is user-friendly.

The projecting through an opening or a detent receptacle in the support shell box defines the horizontal mounting position in the front region of the housing and also provides the support to the front and to the rear viewed in the direction of the longitudinal axis of the support shell. Also perpendicular to this longitudinal axis then a corresponding holder is reached.

A front wall of the box is preferably interrupted and forms a movable snap hook. Together with the resting on the support tray box of the front foot then fixes this snap hook or this snap element, the vertical position in the front region of the housing.

It is preferably provided that in a second slot-shaped opening, in particular a floor-integrated locking receptacle, in the carrier shell a snap hook or a snap element of the further component in a tensile stress digs into this opening. As a result, the snap connection can not solve.

In Fig. 1 is a perspective front view of a household refrigerator 1 shown, which has a designed as an outer housing 2 housing. The housing 2 surrounds an inner container, which defines two different separate inner spaces 3 and 4, wherein the inner spaces 3, 4 are designed for receiving food.

By way of example, the lower interior 4 is closed by a door 5. The upper interior 3 is shown for inspection in this without such a door, which is actually present in the household refrigerator 1, however.

The household refrigerator 1 may be a refrigerator or a freezer or a refrigerated combined freezer. It comprises at least one refrigeration cycle, by means of which a corresponding cold temperature is generated in the interior spaces 3 and 4. The refrigeration cycle includes an in Fig. 2 showing a perspective view of the household refrigerator 1 from behind, shown refrigerant compressor 6 and compressor. The refrigeration cycle also includes, in particular, a condenser and an evaporator. The refrigerant circulates in the circuit.

As in Fig. 2 can be seen, the refrigerant compressor 6 is disposed in a rear lower portion of the household refrigerator 1. This area represents a machine room 12. It is separated from the interiors 3 and 4. The engine room 12 is designed to receive components of the refrigeration cycle.

During operation, the refrigerant compressor 6 generates waste heat which is used to evaporate defrosted water produced in the domestic refrigerator 1, which is collected. For this purpose, the household refrigerating appliance 1 comprises a device 7, which is designed to receive defrosting water and which is likewise arranged in the machine room 12 in at least subcomponents. For this purpose, a collecting tray 8 of the device 7, which is designed to collect defrosting water, is arranged in the machine room 12. It is arranged virtually above the refrigerant compressor 6, so that the thermal coupling is given to the evaporation of the collected defrost water.

The device 7 also includes a collecting bowl 9 for the defrosting water, which is connected by a connecting line 10 with the drip tray 8.

The device 7 further comprises a carrier shell 11, which is provided for receiving the collecting tray 9, and which is also arranged in the machine room 12.

The engine room 12 is bounded by boundary walls.

In Fig. 3 is an embodiment of a carrier shell 11 is shown in a perspective view. This is integrally formed in particular of a metallic material and has a longitudinal axis A. The carrier shell 11 has a bottom 13, on which circumferentially upstanding side walls 14 and 15, which represent longitudinal side walls, which thus extend parallel to the longitudinal axis A, and in a front wall 16 and in a rear wall 17 open. The longitudinal side walls 14 and 15 have at their bottom edge 13 facing away from the upper edge sides C-shaped grooves 18 and 19. The C-shape forms in cross-section and thus in a plane perpendicular to the longitudinal axis A. These grooves 18 and 19 extend substantially over the entire length of the longitudinal side walls 14 and 15th

In the bottom 13 openings 20 and 21 are formed as a locking receptacle. In addition, further recesses 22, 23, 24 and 25 are formed, which are also designed as continuous openings. The openings 22 to 25 are preferably for connection to a further component designed as a compressor or refrigerant compressor 6, which is held fixed in position on the carrier shell 11. In particular, the attachment in this embodiment, at least one snap connection and / or at least one plug connection and / or at least one latching connection designed and beyond readily additional separate fastening element, so that here is a zusatzbefestigungselementfreie or zusatzbefestigungselementlose configuration is formed.

In addition, it is provided that said grooves 18 and 19 slot-like recesses or interruptions 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41 and 42 have , By means of these interruptions 26 to 42, plug-in areas for plug-in elements of a further component to be fastened to the carrier shell 11 are formed in particular, so that plug connections in particular are realized here.

The carrier shell 11 is in Fig. 4 shown in a perspective sectional view, in which case the sectional plane perpendicular to the axis A and is characterized by the γ-z-plane. The C-shaped configuration of the grooves 18 and 19 can be seen, wherein the openings of the C-shape facing each other.

The C-shape is realized by a 180 ° bend of the upper configuration of the side walls 14 and 15.

In Fig. 5 is an enlarged view of a partial section of the view in Fig. 4 shown, whereby also here the corresponding recesses in the form of the interruptions 37 and 38 can be seen.

Due to these possibilities of connecting further components to the carrier shell 11 without additional separate fastening elements, a very fast and yet positionally secure assembly of the respective further components can be carried out individually. By locating the openings 20 and 21 and 22 to 25 and / or the local and shape specific configurations of the interruptions 26 to 42 individually shaped and also in terms of dimensions varying components can be attached thereto. The components can extend over the entire width (direction perpendicular to the longitudinal axis A) and thus in the z-direction between the grooves 18 and 19 and thus be secured opposite to corresponding interruptions 26 to 42 by connectors. In accordance with the smaller in width components, a likewise provided at least two-point attachment on the one hand to at least one interruption 26 to 42, on the other hand at an opening 21 to 25 done.

In Fig. 6 is shown in a perspective view of an example in which a plurality of further components are attached to the support shell 11. These may be electronic units 43 and 44, which are then preferably fastened to the channels 18 and 19 by plug connections and / or snap connections. In addition, an operating capacitor housing 45 may be secured accordingly. The attachment of the refrigerant compressor 6 is already explained above. In addition, the attachment of another evaporation tray 46, which may also be the shell 9, provided with an overlying evaporation grid 47 as a cover.

In these embodiments, an additional fastening element-free connection to the carrier shell 11 is provided in each case.

In Fig. 7 is in a further embodiment, a perspective view of a too Fig. 6 shown different assembly of the carrier shell 11 with other components. Here also the corresponding attachment of the collecting tray 9 to the carrier shell 11 by a snap connection and / or a plug connection and / or a latching connection is shown. In addition, the attachment of a water stop unit (Aquastop unit) 48 is also shown. It should be noted that the electronics unit 43 and the Aquastop unit 48 are secured in the channels 18 and 19 in particular via plug connections and / or snap connections. The collecting tray 9, however, is at least attached via a latching connection to the openings 20 and 21, and may also be at least one side to a channel 18 or 19 connected by an additional connector.

Accordingly, the operating capacitor housing 45 is attached only on one side to a channel 18, on the other hand locked to the bottom 13 via a locking receptacle.

In Fig. 8 is shown in an enlarged perspective sectional view of the attachment of the water stop unit 48 to the carrier shell 11. It can be seen here that plug-in elements 48a engage in the form of position ribs in interruptions, in particular the interruptions 30 and 31, on the channel 18 and are thus inserted accordingly. On the opposite side, the mechanical coupling of the water stop unit to the channel 19 on the one hand by a snap connection 49 and on the other hand also realized by a connector 50. For this purpose, also integrally formed plug-in elements 50a and 50b are provided in the form of position ribs which engage in particular the interruptions 37 and 38 of the channel 19 or are inserted. The snap connection 49 comprises a rotatable foot with a snap element 51 which is pivotable about an axis which is parallel to the longitudinal axis A. In addition, a locking element 52 is provided, by means of which the snapped position of the snap element 51 can be locked.

In Fig. 9 is a perspective view from above of the illustration in FIG Fig. 8 shown.

In Fig. 10 is a view in the direction of the longitudinal axis A on the embodiment in Fig. 8 and Fig. 9 shown. In this regard, the pivoting of the snap element 51 about an axis B, which is perpendicular to the plane of the figure, shown. The snap element 51 has a hook 51 a, which engages in the cavity of the C-shaped groove 19.

In Fig. 11 is a perspective sectional view of a mounting of the electronics unit 43 on the opposite grooves 18 and 19 of the carrier shell 11 is shown. Again, a fixture is provided both via a snap connection 49 and via a plug connection 53, wherein also here again formed as position ribs plug-in elements 53 a and 53 b in interruptions 28 and 29 of the channel 18 are inserted. On the opposite side, the plug-in elements 50a and 50b designed as position ribs, which are inserted into the interruptions 41 and 42, are again integrated into the snap element 51.

In Fig. 12 is here again a view in the direction of the longitudinal axis A on the representation in Fig. 11 shown. As with the representations in Fig. 10 and Fig. 12 can be seen, the attached to the opposite grooves 18 and 19 components are spaced from the bottom 13 so that they are positioned in this regard contactless.

In Fig. 13 the attachment of the collecting tray 9 to the support shell 11 is shown in a perspective sectional view, wherein also here a fixing principle is realized, as it is already in the 8 to 12 to the water stop unit 48 and the electronic unit 43 has been explained. Reference is therefore made in this respect to the corresponding explanations.

The previously discussed further components in the form of the collecting tray 9, the electronics unit 43 and the water stop unit 48 have these dimensions in the z-direction and thus perpendicular to the longitudinal axis A, which are dimensioned over the entire distance between the grooves 18 and 19.

In Fig. 16 the already mentioned component of the operating capacitor 45 is shown, which is shorter in this z-direction, than the distance between the grooves 18 and 19. An attachment to opposite grooves 18 and 19 is therefore not possible.

The operating capacitor housing 45 therefore has on one side at one end position ribs as plug-in elements, wherein in this embodiment, only one plug element 53a is formed. Adjacent thereto and parallel running stationary snap elements 51 a, 51 b and 51 c are formed, which engage in the cavity of the C-shaped groove 18. In addition, at the opposite ends tabs as support ribs 54 and 55 ( FIGS. 17 and 18 ) wing-like and obliquely formed standing backwards. With these support ribs 54 and 55, the operating capacitor housing 45 is supported on the bottom 13, possibly also engaging in openings 56, wherein in the perspective sectional view in Fig. 15 the attached state of the operating condenser housing 45 is shown on the carrier shell 11. In addition, the operating capacitor housing 45 comprises a box 57 penetrating through the carrier shell 11, as in FIG Fig. 17 is shown. With its particular snap hook latching takes place with the bottom 13, in which case a locking connection between the box 57 and an opening in the form of a locking receptacle in the bottom 13 is thus formed. In FIGS. 17 and 18 the design of the operating capacitor housing 45 with the respective connection elements is shown in the respective respective perspective representations.

In Fig. 19 is a perspective sectional view of the assembled operating capacitor housing 45 on the carrier shell 11 is shown. Here also the connected state of the support rib 54 in the opening 58 in the bottom 13 is shown. In addition, the snapped state of the snap element 51c in the channel 18 can also be seen.

In Fig. 20 is a perspective view with bottom view of the embodiments in Fig. 15 and Fig. 19 shown. It is also the locked state here of the box 57 in the bottom 13. For this purpose, a latching element 57a and an element 57b engage in the openings 20 and 21 and latch therein.

As a result, a latching connection 59 is formed.

In Fig. 21 an enlarged view is shown. In particular, the element 57b is preferably formed as a pure plug-in element, which is then not locked in the opening 20, but only plugged in, so that here is a plug connection with integrated latching connection is formed, in which case then the latching element 57a locked accordingly.
