Description

The invention relates to a household refrigerator with a housing in which a receiving space for food is formed. The receiving space is delimited by walls of an inner container. An additional compartment for food is formed in the receiving space, which has boundary walls, through which a receiving volume of the additional compartment is limited. Furthermore, the invention also relates to a method for forming such an additional subject.

In household refrigeration devices for storing food, such as a refrigerator or a freezer or a fridge-freezer combination device, it is known that the corresponding receiving space, which can be a refrigerator compartment or a freezer compartment, can be subdivided by insertable horizontal plates, which can be shelves is. Food can then be applied to these shelves. However, such shelves do not form an individual, limited additional compartment in the receiving space, but rather the receiving space itself is subdivided into sub-areas which are, however, coherent and not completely separated from one another.

In addition, it is known that a separate additional compartment, which can be a fresh-keeping compartment, for example, is formed in such a receiving space. This specific additional subject is limited by walls, so that the volume of this additional subject is defined and closed. In known designs of such additional subjects, however, these are predetermined and formed in the receiving space.

From DE ° 10 ° 2007 ° 021555 ° A1 of JP ° H03 ° 91681 ° A, individually considered containers for refrigeration devices are known which are individually delimited by firmly connected walls. The internal volume of each container can be divided by individual dividers. The same is known from EP 2 ° 752 ° 632 ° A2.

It is an object of the present invention to provide a household refrigeration device and a method in which or with which such an additional compartment can be provided in a more needs-based manner.

This object is achieved by a household refrigerator and a method according to the independent claims.

A household refrigerator according to the invention comprises a housing in which a receiving space for food is formed. This receiving space is delimited by walls of an inner container. An additional compartment for food is formed in the receiving space and has boundary walls or outer walls. A receiving volume of the additional compartment is delimited by these boundary walls and is therefore delimited by at least one boundary wall on all sides that determine the geometry of the additional compartment. This receiving volume of the additional compartment is thus particularly limited on all sides and thus also completely delimited from the remaining volume of the receiving space.

An essential idea of the invention is to be seen in the fact that these boundary walls of the additional compartment can be separated and joined together in a non-destructive manner and the additional compartment can thereby be reversibly assembled and disassembled in the receiving space. This configuration essentially increases the usability of the additional subject and thus also makes it more flexible and variable. Such a possibility of simple dismantling and then, if necessary, building up again increases the usability of the additional subject considerably. If it is not needed, it can be dismantled quickly and easily, and the space in the recording room that is then freed up can be used for other purposes. If, however, the additional compartment is required, it can be set up quickly and form a receiving volume, which is then completely enclosed and defined by the boundary walls. This also increases the usability of the entire household refrigeration device and the design of the recording room can be very flexible and user-specific.

The additional compartment has such a number of boundary walls that, regardless of its geometry, each side of this geometry is at least one boundary wall and thus the additional compartment on each of these sides of the geometry is formed at least one boundary wall and thus the receiving volume is limited accordingly.

The additional compartment is arranged separately from a door that closes the receiving space in the receiving space. The additional part is therefore not arranged on the door. In a preferred embodiment it is provided that the additional compartment is a fresh-keeping compartment, in which an air humidity that is different from the receiving space and / or a temperature that is different from the receiving space can be specifically set. With such a configuration, an individual zone can thus be created in the receiving space, in which different storage conditions for food can be set for the remaining volume of the receiving space. As a result, different foods can be stored more appropriately and thus the shelf life and freshness can be individually maintained longer.

In a particularly advantageous embodiment, it is provided that the additional compartment can be set up at a first defined position in the receiving space or can be set up at at least one further and different second defined position in the receiving space. Such location flexibility is advantageous with regard to the accessibility to the additional compartment and to the then remaining partial volume of the receiving space. A user can then meet his needs and individually positionally form the additional subject. This may also result in ergonomic advantages with regard to the accessibility and thus the equipability of the additional compartment and also with regard to the removal of food therefrom. In addition, this version also enables the additional subject to be set up at different positions depending on the situation. Depending on the foodstuffs to be stored in the remaining volume of the receiving space and, for example, on the amount and / or size of these foods, the first position or the second position may then be more advantageous for the additional compartment. This means that a user can react as flexibly as possible in these individual situations. In practice, this has significant advantages over designs in which an additional compartment is specified by the manufacturer at a single fixed position in the receiving space and this additional compartment is arranged in an unchangeable location.

It can also be provided that the additional compartment in its assembled state and thus in the state arranged in the receiving space can be moved from the first position to the second position, in particular can then be moved as a whole, and / or from the second position to the first Position can be brought. With such an embodiment, the disassembly process or The process of dismantling the additional subject and then building it up in a different position is no longer necessary, but the additional subject can then be changed in its position quickly and easily.

In particular, it can be provided that mechanical coupling means are provided on the inner sides of the inner container and / or on boundary walls of the additional compartment, which enable such a change in position, in particular a shift. For example, these can be sliding runners which engage in corresponding depressions or grooves.

In the case of boundary walls of the additional compartment, it can generally be provided that these walls have coupling means, so that the boundary walls can be mechanically connected to one another, these coupling means being detachable without destruction. In this context, plug connections or snap connections can be provided. Other connecting means can also be provided as an alternative. At specific points it can also be provided that the boundary walls of the additional compartment are only in direct contact with one another, for example in contact with one another via a sealing element, so that no specific mechanical connecting means are then provided here.

It is advantageously provided that the position at which the additional compartment can be set up in the receiving space can be selected depending on which wall of the inner container is to form which locally specific boundary wall of the additional compartment. It is envisaged that the additional compartment is not constructed exclusively from separate boundary walls, but, for example, at least one boundary wall is formed by a wall of the inner container, but, depending on this, the position of the additional compartment in the receiving space is preferably such that this wall of the inner container then also the intended one Provides boundary wall of the additional compartment. Such a configuration can then save at least one separate boundary wall of the additional compartment and thus reduce the total number of components of the household refrigeration device.

It is preferably provided that the position of the additional compartment in the receiving space is arranged above the second position in the height direction of the household refrigerator. As a result, the additional compartment can be formed further up or down in the vertical direction, as a result of which, depending on the position of the household refrigeration device, a height position of the additional compartment that is advantageous for a user can be built up individually. If the household refrigeration device is, for example, a free-standing device and is therefore on the floor, a different individual height position of the additional compartment can be advantageous for a user than if the household refrigeration device is a built-in device and is to be installed at a certain height in an installation niche. In order to be able to take these requirements and circumstances into account very individually, this possibility of setting up at least two different positions in the additional subject is particularly advantageous.

It is preferably provided that the additional compartment has a front wall, a bottom wall, a top wall, a rear wall and side walls as separate boundary walls. In this embodiment, the additional compartment is thus particularly cuboid or cube-shaped.

It is envisaged that the additional compartment has at least one further separate boundary wall which is arranged in the receiving volume. This further separate boundary wall is a partition with which the receiving volume of the additional compartment can be separated into at least two partial volumes. As a result, the additional compartment can be individually designed and the functionality increased. Because of the at least two partial volumes that can then be individually designed, individual storage conditions for food that can be introduced therein can also be set. Advantageously, this partition can be used in the receiving volume in a non-destructive manner and can be removed again, so that here too, the additional compartment itself has a very high degree of flexibility with regard to the interior design.

It is advantageously provided that the partition is a thermal insulation wall. As a result, the partial volumes can be thermally insulated from one another, so that the different storage conditions in the partial volume can also be set here without the respective other partial volume being undesirably influenced.

In this context it can also be achieved that different temperatures and / or different air humidities can be set in the partial volumes.

It is provided that the partition wall has at least one flow channel, with which cold air can be conducted from the outside of the additional compartment into the receiving volume of the additional compartment. This makes it possible to set particularly advantageous storage conditions with cool temperatures, but preferably above freezing point, which is particularly advantageous for fruit and vegetables, but also for fish, for example, and which keeps the shelf life of these foods and the freshness of these foods longer.

In particular, it is provided that the additional compartment as a separate boundary wall has a frame with a through opening that forms a front wall of the additional compartment. This is a further very advantageous embodiment, since additional components can also be introduced into the additional compartment, for example a bowl in which food can be accommodated. This shell can then simply be inserted over the frame designed as a front wall and thus extends through the through opening into the receiving volume of the additional compartment. In particular, it is then provided that such a shell or a corresponding container abuts the frame in the fully inserted state and in this respect the passage opening is then covered by the shell, in particular a front wall of the shell. In particular, a completely enclosed receiving volume of the additional compartment is then also provided in such a configuration.

It is advantageously provided that the frame has at least two separate through openings. This is particularly advantageous if there is also a partition, as mentioned above. Individual separate trays or containers can then be introduced into the respective partial volume of the receiving volume of the additional compartment through the respective through openings. As a result, two shells, viewed in the width direction of the household refrigeration device, can be arranged next to one another and preferably at the same height. They are then easily accessible and the assembly and removal are very user-friendly.

It is preferably provided that the additional compartment has at least one receptacle for food, which is arranged so that it can be pushed and pulled out into the receptacle volume formed by the boundary walls through the through opening. This makes it particularly easy to insert and remove food from the additional compartment. None of the boundary walls have to be removed completely in order to be able to get into the receiving volume. By simply and user-friendly moving only the receiving tray, the food contained in the receiving tray can then be removed very easily or appropriate foods can be brought into the receiving tray.

In particular, it is provided that a sealing element is arranged around a through opening on a front side of the frame, on which the receiving shell lies in the inserted state. This is a further advantageous embodiment, since the through openings are thus not only concealed at the front by a front wall of the receptacle in the inserted state, but also an undesired escape of air humidity is prevented here. On the other hand, a temperature adjustment between the, in particular, colder receiving volume of the additional compartment to the remaining partial volume of the receiving space can at least be significantly reduced.

Advantageously, the frame is pushed into separate holding bars on opposite sides. As a result, the frame is precisely positioned and kept stable. The reversible attachment and removal is particularly easy, and wear is avoided even with frequent assembly and disassembly of the frame, so that even with frequent assembly and disassembly, a wobble-free fit of the frame is possible on the holding bars. In addition, this type of mounting of the frame enables very quick assembly and disassembly, which is also very easy to carry out.

A further aspect of the invention relates to a domestic refrigeration device with a housing in which a receiving space for food is formed, this receiving space being delimited by walls of an inner container. An additional compartment for food is formed in the receiving space, which has boundary walls, through which a receiving volume of the additional compartment is limited. In particular, in this aspect it is provided that the additional compartment can be set up at a defined first position in the receiving space or can be set up at at least one further second defined position in the receiving space. The advantages that can be achieved in this way have already been mentioned above. In particular, it can be provided that fastening means for one or more boundary walls of the additional compartment are provided on the walls of the inner container for these two defined positions.

Embodiments of the first aspect of the invention are to be regarded as advantageous embodiments of this further aspect of the invention.

Another independent aspect of the invention relates to a domestic refrigeration device with a housing in which a receiving space for food is formed, which is delimited by walls of an inner container. An additional compartment for food is formed in the receiving space, which has boundary walls, through which a receiving volume of the additional compartment is limited. An essential idea of this aspect of the invention is to be seen in the fact that the additional compartment has at least one further separate boundary wall, which is a dividing wall with which the receiving volume of the additional compartment can be separated into at least two partial volumes. The partition can be made in one piece or in several parts.

As a result, individual zones can be formed in the additional compartment, in which different storage conditions for food can be set.

In addition, the invention also relates to a method for forming an additional compartment for accommodating food in a receptacle for food in a household refrigeration device. In the method, separate boundary walls, from which the additional compartment is built, are provided, and the boundary walls are arranged in the receiving space in such a way that a receiving volume of the additional compartment is created. The receiving volume is therefore on all geometric sides by a Boundary wall limited at least in some areas. The receiving volume is in particular completely limited on the circumference by the boundary walls. The boundary walls are detachably connected so that the additional compartment can be reversibly dismantled and reassembled. The advantages that can be achieved in this way have also already been mentioned above in the presentation of the various aspects of the household refrigeration device.

In particular, a first defined installation position is specified in the receiving space, at which the additional compartment can be constructed in a modular manner, and at least a second defined installation position, at which the additional compartment can be constructed in a modular manner, is specified.

The additional compartment with its boundary walls is therefore made available as a modular kit that can be installed individually at different positions in the recording room.

In principle, it is therefore also possible to offer the additional compartment as a retrofit kit, so that a user of a household refrigeration device can subsequently procure this retrofit kit if he wishes such an additional compartment.

The additional compartment is designed as a fresh-keeping compartment, in which a different temperature and / or a different atmospheric humidity can be set or set in comparison to the remaining volume of the receiving space. In particular, the household refrigeration device comprises an adjusting device for this purpose.

The additional compartment can have one or more air channels with which this cold and / or moist air can be introduced into the additional compartment.

In particular, it is provided that the additional compartment is arranged in a receiving space of the domestic refrigeration device designed as a cooling compartment, so that it can be reversibly assembled and removed again in a non-destructive manner. In particular, the household refrigeration device has at least one further receiving space in this receiving space, which is designed as a cooling compartment and is in particular designed as a freezer compartment. Is viewed in the vertical direction and thus in the vertical direction of the household refrigeration device the refrigerator compartment is preferably formed above the freezer compartment. The cooling compartment can be closed by a single door, but can also be closed by two pivotable doors arranged next to one another. The freezer compartment can be closed by a separate door, the doors representing front components of the household refrigeration device and, in the closed state, preferably extending in one plane.

It can be provided that a boundary wall of the additional compartment, which represents a bottom of the additional compartment, is formed by a bottom of the inner container. This can be provided in a specific first position or a corresponding first installation position of the additional compartment in the receiving space. If, in fact, the additional compartment is to be formed at the very bottom of the receiving space in the height direction of the receiving space, it is advantageous if such an already existing wall of the inner container, namely the bottom, is then also used as the bottom for the additional compartment.

The same can be provided if a different, different installation position is provided in the upper region of the receiving space, so that here, for example, a ceiling of the inner container is used as the ceiling wall of the additional compartment.

If, on the other hand, an installation position of the additional compartment is provided at a distance from the ceiling and the bottom of the inner container, a wall which is otherwise used as a shelf and which can be inserted vertically in the receiving space between the ceiling and the bottom of the inner container can also be used as the ceiling of the additional compartment. With such a configuration, on the one hand, the additional compartment can be limited upwards by this separate boundary wall, on the other hand, other storage goods can then also be placed on it.

If a refrigerator compartment and a freezer compartment are formed in a single inner container and are separated from one another by a thermally insulated partition, this thermally insulating partition of the inner container can also be a top wall or a bottom wall of the additional compartment.

In one embodiment of the invention, the additional compartment extends over the entire width of the receiving space. However, it can also be provided that this additional compartment extends only over a partial width of the receiving space, for example over half or a third or three quarters of this width of the receiving space. This width of the receiving space extends between the opposite vertical side walls of the inner container. It can be provided that the above-mentioned embodiment, in which the additional compartment has a partition as a further separate boundary wall, with which the receiving volume of the additional compartment can be subdivided into at least two separate partial volumes, has a plurality of air channels which, on the one hand, into the first partial volume, and on the other hand into the second partial volume flow out.

With the information "top", "bottom", "front", "back," horizontal "," vertical "," depth direction "," width direction "," height direction "etc., these are in accordance with the intended use and arrangement of the device and at given a position and orientation given in particular in front of the device and looking towards the device.

Identical or functionally identical elements are provided with the same reference symbols in the figures.

In Fig. 1 an embodiment of a household refrigeration device 1 is shown in a perspective view. The domestic refrigeration device 1, which is designed for storing and preserving food, comprises a housing 2. In the housing 2, a first receiving space for food is formed, which in the exemplary embodiment is a cooling compartment 3. In addition, at least one further receiving space, which is a freezer compartment 4, is formed in the housing 2. The freezer compartment 4 can be closed by a separate door 5, which in Fig. 1 is shown in the closed state. The door 5 can be a front wall of a drawer which can be pushed into and pulled out of the freezer compartment 4.

The cooling compartment 3 can be closed at the front by a single door which is pivotally arranged on the housing 2. In the exemplary embodiment it is provided that the cooling compartment 3 can be closed at the front by a door 6 and a further door 7. The two separate doors 6 and 7 can each be pivoted about a pivot axis oriented in the height direction (y direction).

In the refrigerator compartment 3, the number and position and configuration are only to be understood as examples, shelves 8 and 9 are arranged at different heights and thus on different levels. They are particularly on the inside of opposite walls 10 and 11 ( Fig. 2 ) can also be arranged on a rear wall 12. The walls 10 and 11, the vertical side walls represent, the rear wall 12 and a top wall 13 and a bottom wall 14 represent walls of an inner container 15. These walls 10 to 14 also limit the cooling compartment 3, the bottom wall 14 of the cooling compartment 3 also a partition between the cooling compartment 3 and the freezer compartment formed below is.

In the exemplary embodiment, an additional compartment 16 is also formed in the cooling compartment 3. The additional compartment 16 is designed to hold food. It has several separate boundary walls, through which a receiving volume 17 ( Fig. 2 ) is limited. In particular, the receiving volume 17 is delimited on all sides by boundary walls of the additional compartment 16, so that it is a completely closed space.

The boundary walls of the additional compartment 16 are designed to be non-destructively detachable, so that they can be separated and assembled without destruction. The additional compartment 16 is thereby reversible in the receiving space and thus in the cooling compartment 3 can be assembled and disassembled.

The modular structure of this additional compartment 16 thus makes it possible to generate this additional compartment 16 in the cooling compartment 3 in a user-specific manner, but then also to dismantle it again.

Depending on requirements, this additional compartment 16 can thus be present or non-existent and can then be used with regard to its functionality in the cooling compartment 3 or, if it is not required, can be dismantled.

The additional compartment 16 is in particular a fresh-keeping compartment, in which an air humidity different from the remaining volume of the cooling compartment 3 and / or a temperature different from the remaining volume of the cooling compartment 3 can be set in a targeted manner. For this purpose, the household refrigeration device 1 comprises an adjusting device, as will be explained in the following.

In Fig. 1 the additional compartment 16 is shown set up and is also set up at an exemplary first defined position in the cooling compartment 3. The additional compartment 16 is constructed here in the lower area of the cooling compartment 3.

The additional compartment 16 here comprises a ceiling wall 18 as a separate boundary wall, as shown in FIG Fig. 2 is shown. In this Fig. 2 a partial section of the inner container 15 of the household refrigeration device 1 is shown. This ceiling wall 18 represents a separate component which can be removed from the cooling compartment 3 and reinserted. It can also be a shelf on which additional storage goods can then be placed from above. In the exemplary embodiment, this ceiling wall 18 then also provides a partition wall to a further, self-contained storage space 19 ( Fig. 1 ), which is also formed in the cooling compartment 3.

As in Fig. 2 Furthermore, the additional compartment 16 has a separate front wall 20 as a further boundary wall. In the embodiment shown, this front wall 20 is a frame 21 which has at least one, in the exemplary embodiment two, through openings 22 and 23. The frame 21, viewed in the depth direction (z direction) of the household refrigeration device 1, is arranged at a distance from the rear wall 12, offset to the front. The additional compartment 16 extends in the exemplary embodiment over the entire width of the cooling compartment 3, this width being dimensioned in the width direction and thus in the x direction of the household refrigeration device 1. An additional compartment 16 can also be provided, which has a smaller width in this regard.

In addition, a further boundary wall of the additional compartment 16 is formed by the side wall 10 and a further boundary wall by the side wall 11 of the inner container 15. In the embodiment shown, a boundary wall of the additional compartment 16 is also formed by the bottom 14 of the inner container 15.

To fasten the separate boundary walls in the form of the top wall 18 and the front wall 20 to the inner container 15, locally fastening means are provided on the inner container 15 and / or the top wall 18 and / or the front wall 20.

A defined first installation position of the additional compartment 16 in the cooling compartment 3 is then also predefined, in particular, by these locally arranged fastening means. Through the openings 22 and 23 receiving trays 24 and 25, as in Fig. 1 are shown, are pushed through, so that they are then arranged at least in regions in the receiving volume 17. As in Fig. 1 can be seen, front walls 24a and 25a of the receiving shells 24 and 25 in the inserted state of the receiving shells 24 and 25 are also front walls which completely cover the through openings 22 and 23 on the front side. In particular, it is provided that a first sealing element 26 is arranged around the through opening 25 on a front side 20a of the front wall 20, in particular completely around it. A further sealing element 26 is arranged on this front side 20a circumferentially, in particular completely circumferentially, around the further through opening 23. In the closed state of the receiving shells 24 and 25, the front walls 24a and 25a then bear against these sealing elements 26 and 27 on the back, so that a corresponding sealing effect is also achieved here.

It can also be provided that at least one receiving shell 24 and / or 25 has a cover 28 ( Fig. 3 ) or a cover 29 ( Fig. 4 ) with which the receiving shells 24 and 25 are covered from above. The covers 28 and 29 can also be adjusted in their position relative to the receiving shells 24 and 25 by an adjusting device. As a result, the receptacle 24 or 25 can be completely covered from above, or a certain opening gap can be set between a cover 28, 29 and a receptacle 24, 25 by lifting the cover 28, 29 in stages. As a result, the temperature and / or air humidity prevailing in the interior of the receiving shell 24 or 25 can be changed individually.

In Fig. 3 is a sectional view taken along the section line III-III in Fig. 1 shown.

In Fig. 4 a perspective front view shows a representation of subcomponents of the additional compartment 16. The receiving trays 24 and 25 are shown here. The top wall 18 and the front wall 20 as a frame 21 can also be seen.

In Fig. 5 is a side view of the configuration according to Fig. 4 shown.

In Fig. 6 is a rear perspective view of the components of the additional compartment 16 as shown in FIG 4 and 5 are shown from different perspectives or views.

This illustration also shows a further separate boundary wall of the additional compartment 16, this further separate boundary wall representing a partition wall 30. This partition 30 is arranged in the receiving volume 17 of the additional compartment 16, so that, as in FIG Fig. 2 it can already be seen that this receiving volume 17 is divided into two partial volumes 17a and 17b. The partition 30 is preferably a thermal insulation wall, so that the two partial volumes 17a and 17b can also be thermally insulated from one another. As a result, different storage conditions can in turn be set independently of one another in this partial volume 17a and 17b.

In particular, one or more air channels are formed in the partition wall 30, the air channels opening at a rear edge 30a. In Fig. 6 an opening of a first air channel 31 and an opening of a second air channel 32 are shown. The air channels 31 and 32 open into a respective one of the partial volumes 17a and 17b, wherein, for example, the air channel 31 can open into the partial volume 17b and the air channel 32 into the partial volume 17a. In particular, the partition wall 30 and the two air ducts 31 and 32 can be coupled to a further air duct system in the household refrigeration device 1, so that cold air and / or air provided with a certain degree of moisture can be introduced individually into the partial volumes 17a and 17b.

This partition 30 can be formed in one piece, but can also be composed as a multi-part component. Further explanations are then given below.

In Fig. 7 a perspective view of the frame 21 is shown. As can be seen here, the frame 21 is constructed, at least in some areas, in the manner of a truss and thus has, at least in some areas, a certain stiffening structure 33 in which a plurality of struts 34 are arranged;

The frame 21 is in particular formed in one piece, in particular from plastic.

In Fig. 8 it is shown how the frame 21 can be mounted on two separate holding bars 35 and 36. These rectilinear holding bars 35 and 36 can preferably be attached, in particular screwed, at defined positions on the inner container 15, in particular on the inner sides of the vertical side walls 10 and 11. For this purpose, defined connection points are preferably specified on these vertical side walls 10 and 11, in particular screw domes are specified in a fixed manner. As a result, different positions are then also specified for the holding bars 35 and 36, so that these holding bars 35 and 36 can be attached, at least in the height direction of the domestic refrigeration device 1, at at least two different height positions and thus at two different positions. As a result, in particular two different positions or installation positions for the additional compartment 16 are then specified in this height direction.

In addition or instead of this, it can also be provided that at least two different depth positions are predefined in the depth direction (z-direction) of the household refrigeration device 1, to which the holding homes 35 and 36 can be attached, in particular screwed on. With this configuration, dimensions of the additional compartment 16 can be set both in the depth direction and the general position in the height direction can be selected.

In Fig. 8 it can also be seen that the frame 21 has grooves on receptacles 37 and 38 on opposite sides, in particular vertical sides, into which the holding bars 35 and 36 engage. The frame 21 can then be pushed onto the side walls 10 and 11 when the holding bars 35 and 36 are fastened at their desired positions. In Fig. 8 a partially postponed intermediate assembly state is shown here, whereas in Fig. 7 the fully deferred final state of the frame 21 is shown on the holding bars 35 and 36.

In Fig. 9 is a front view of the component representation in Fig. 2 shown, here the frame 21 is shown in the intermediate mounting position on the holding bars 35 and 36, as shown in FIG Fig. 8 is shown.

The partition 30 is already pre-assembled here and arranged in its end position. As can be seen here, the frame 21 is preferably also fastened to this partition 30. For this purpose, on the back of an intermediate web 39 ( 7, 8 ) of the frame 21 is also formed a receptacle 40, which can be a depression or a groove or a groove. The dividing wall 30 also has a spar-like element 30b on its front side 30c, which engages in this receptacle 40 when the frame 21 is pushed onto the holding spars 35 and 36 and the dividing wall 30 is mounted beforehand.

In Fig. 10 is shown in the perspective view of the assembled final state of the frame 21, in which case the engagement of the element 30b in this receptacle 40 can also be seen. The partition 30 can be plugged onto the base 14 or locked or screwed on. Correspondingly, a connection to the rear wall 12 can also be provided, or it can also be provided here that the partition wall 30 only rests against the rear wall 12 with a rear surface or the rear edge 30a.

In Fig. 10 further support webs 41 and 42 can also be seen on the side walls 10 and 11, which are formed in one piece. The top wall 18 of the additional compartment 16 can then be placed in particular on these webs 41 and 42.

In Fig. 11 In a simplified vertical sectional view (sectional plane corresponds to the yz plane), a household refrigeration device 1 is shown, in which the additional compartment 16 is arranged in a first defined installation position when viewed in the vertical direction. The bottom 14 here is a thermally insulating partition, in particular the inner container 15, with which the cooling compartment 3 is separated from the freezer compartment 4. The air duct 31 is shown here. The receptacle volume 17 can be a coherent receptacle volume and the partition 30 can therefore not be present. If the partition wall 30 is optionally present, then via the air duct 31 in the partition wall 30 via corresponding openings 31a ( Fig. 10 ) cold and / or air provided with appropriate air humidity are introduced into the partial volume 17b.

In Fig. 12 is corresponding in a vertical sectional view Fig. 11 shown a further embodiment or a further type of installation, in which the additional compartment 16 in one too Fig. 11 differently defined second position or installation position in the cooling compartment 3 is constructed. Due to this modular construction of the additional compartment 16 with the separate boundary walls, different positions in the cooling compartment 3 can also be specified, at which then this construction of the additional compartment 16 is made possible. As can be seen here, the second position, viewed in the height direction, is above that in FIG Fig. 11 shown first position. A bottom of the additional compartment 16 is formed here by a, in particular freely projecting, shelf 44. It can also be used in addition to the 11 and 12 Two different high-level positions shown by way of example, further high-level positions may be provided and / or, in addition, different positions in the depth direction for the additional compartment 16, at which it can be constructed, may also be provided.

The boundary walls of the additional compartment 16 are preferably thermal insulation walls, as a result of which no undesired adjustment of the storage conditions in the additional compartment 16 to the remaining volume of the cooling compartment 3 occurs. Accordingly, the frame 21 is then advantageously designed as such a thermal insulation wall.

In this embodiment too, a bottom 43 of the inner container 15 is the bottom of the freezer compartment 4.

In particular, it is provided that the household refrigeration device 1 has a refrigeration circuit, some components of which can also be arranged in a machine room 45 of the household refrigeration device 1. As in the exemplary embodiment according to 11 and 12 It can be seen that an evaporator 46 of this refrigeration circuit 45 is arranged in the freezer compartment 4, but is separated from it by a partition 47. An evaporator chamber 48 is thereby formed. In particular, in this evaporator chamber 48 there is preferably also a fan, not shown, which blows cooled air on the evaporator 46 into the freezer compartment 4 and into the cooling compartment 3 via a channel 49 running in the rear wall of the inner container 15.

This channel 49 ends at an outlet 50. A first outlet 50 and a second outlet 51 are preferably provided, so that here a coupling of the channel 49 to the air channels 31 and 32 is possible at different altitudes. It can it should be provided that the outlets 50 and 51 can be closed, for example, by self-closing flaps. As a result, when building the additional compartment 16 on the in Fig. 11 In the first position shown, the air channels 31 and 32 are coupled to the outlet 50 and the flap closing the outlet 50 is then opened, for example automatically, in particular when the partition 30 is inserted. In this position according to Fig. 11 the flap, which can close the outlet 51, is then closed. On the other hand, the structure of the additional compartment 16 on the in Fig. 12 shown further position is provided, this flap closing the outlet 51 is then opened, whereas the flap closing the outlet 50 is closed.

Air is passed through a further passage opening 52 out of the cooling compartment 3 via a channel 53, in particular in a side wall of the housing 2, back to the evaporator chamber 48.

It can also be provided that the cold air flowing into the partial volumes 17a and 17b via the air channels 31 and 32 reaches, for example, a front edge of the ceiling wall 18 and the passage openings 22 and 23 in the remaining volume of the cooling compartment 3, if an embodiment is provided there , which does not require a corresponding tightness, as was explained in the above examples, and thus a certain exchange of air humidity and / or temperature should also be provided between the receiving volume 17 and the remaining area of the cooling compartment 3.

Instead of the two separate air ducts 31 and 32, a single duct can also be provided in the partition wall 30, which then preferably has outlet openings 31a on both sides, so that both partial volumes 17a and 17b can be supplied with the same cold and / or moist air. However, these two separate air channels 31 and 32 are preferably provided.

As already explained, this partition 30 can be formed in one piece. However, it can also be designed in several parts and, for example, be configured as follows Fig. 13 is explained. It can be provided here that the separate components of this partition 30 are in particular four components which are joined together. For this purpose, two insulating bodies 54 and 55, in particular the same, can be provided. These can be made of a heat-insulating material, such as for example expanded polystyrene. In addition, two shell parts 56 and 57 can also be provided, which represent outer end plates and surround the insulating bodies 54 and 55 and thus virtually represent a shell for these insulating bodies 54 and 55. In particular, these shell parts 56 and 57 are made of solid plastic. The shell parts 56 and 57 preferably each have an in particular flat base plate 58, which each form one of the flanks of the partition wall 30 and in which the air passage openings 31a and 32a are formed. The base plates 58 are surrounded by a circumferential web 59. At a lower rear corner 60, the shell parts 56 and 57 are preferably blunted or rounded, so that they can be used to fit the transition between a rear wall 12 and a bottom 16, which is particularly rounded on a deep-drawn inner container 15. In the rear section of the web 59, two recesses 61 are formed on both shell parts 56 and 57, which are aligned with the air channels 31 and 32.

The insulating bodies 54 and 55 preferably each have the shape of flat cuboids, on the facing main surfaces of which two horizontally extending grooves 62 and 63 are formed as depressions, the upper groove 62 being aligned with the air passage openings 32a in the upper half of the shell part 56. The insulating body 55 differs from the insulating body 54 only in its orientation. Both can be converted into one another by a 180 ° rotation about a horizontal axis 64, so that each air duct 31 or 32 is delimited by an insulating body 54, 55 on the groove 62 and the other on the groove 63. Passages 65 in the insulating body 54 are aligned with air passage openings 32a. Correspondingly, passages 66 in the insulating body 55 are aligned with the air passage openings 31a.
