Description

The invention relates to a household refrigerator with a housing in which at least a first receiving space for food is designed as a refrigerated compartment. In the housing, a second receiving space separate from the first receiving space is designed as a freezer compartment. The household refrigeration appliance moreover comprises a beverage appliance which is designed to produce and dispense a beverage.

From the DE 196 15 106 A1 For example, a method and apparatus for continuously producing soda water or soda-like water is known. There, a device is disclosed in which in different separate containers different liquids such as lemonade, beer, wine can be present. Each container is connected to its own tap and is thus separated from the other container. Generating and dispensing a mixed beverage of different liquids in the containers is not possible in the interior of the plant itself. The taps are also far apart, so that a simultaneous introduction of liquids from different taps in a drinking vessel is not possible.

From the WO 2007/141321 A2 is a household refrigerator known, which is designed as a beverage device for dispensing a drink on this household refrigerator itself.

In addition, the preparation of mixed drinks from two liquids through a beverage device in a household refrigerator consuming. The liquids are, in order to produce the mixed beverage differentiated, defined by different compositions and thus different physical properties. This is limited in conventional known devices with respect to the temperature allows. It is the shelf life and thus durability of different liquids currently only partially possible or only for a short time. Also, the generation and output of then specific tempered mixed drinks is only very limited possible.

Also, so-called no-frost household refrigerators are known, for example from the DE 10 2010 041 952 A1 ,

It is an object of the present invention to provide a household refrigerator, in which the production of mixed drinks from two different liquids in a beverage appliance of a household refrigeration appliance can be made as needed.

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

An inventive household refrigerator comprises a housing in which at least a first receiving space for food is designed as a refrigerated compartment. The household refrigerating appliance moreover comprises a second receiving space which is separate from the first receiving space and which is designed to receive food and is designed as a freezer compartment. The domestic refrigerator further comprises a beverage device, which is a mixed beverage generating device and is designed for the production and dispensing of a beverage, which may also be a mixed beverage. It is in particular provided that the beverage device has a first container for receiving a first liquid which can be added to a beverage to be dispensed. In addition, the beverage device comprises a separate second container, which is designed to receive a second liquid for a beverage to be generated and dispensed. It is envisaged that the first container is thermally coupled only to the refrigerating compartment and the second container is thermally coupled only to the freezer compartment. By means of this embodiment, it is thus achieved that the respective separate containers can be tempered individually and independently of one another. This also means that the containers can be kept at different temperature levels, which in turn has a corresponding effect on the then each introduced therein liquids. As a result, these liquids can be tempered differently, which has advantages in terms of storage life. In particular, a significant advantage is the fact that individualized temperature control of a mixed beverage produced therefrom can be achieved by the different temperature control of the liquids, without then having a corresponding Nachtemperierung to achieve such a preferred mixed beverage temperature after the production of the mixed beverage.

Another very important advantage of the invention is to be seen in that an already existing cold energy is already used by the thermal coupling to the individually cooled compartments of the household refrigerator, so as to be able to temper the container individually each time. There is therefore no additional additional refrigeration or refrigeration device for the corresponding temperature control of the container required. This also allows a very energy-efficient temperature control of the container.

It is in the context then also possible that on the one hand liquids whose freezing point are higher than, for example, the Temperature, as prevail in a freezer, can be cooled without it would freeze. For this purpose, it is advantageous that this liquid is introduced into the container, which is thermally coupled to the refrigerating compartment. On the other hand, liquids whose freezing point is significantly lower than 0 ° C. can then be subjected to thermal treatment with lower temperatures prevailing in the freezer, without them freezing.

For example, water may be provided as a first liquid in a first container. As a second liquid in the second container may be provided alcohol or an alcoholic liquid.

It is preferably provided that the two containers are separated from each other by a thermally insulating partition wall. As a result, no thermal influence can take place, so that the individual and independent tempering is improved.

It is particularly advantageous if the domestic refrigerator is a no-frost domestic refrigerator with a no-frost refrigeration device. In a no-frost household refrigeration appliance, this is cooled by means of a forced-ventilation heat exchanger. Since the cooling temperatures of the different liquids in the two containers of the beverage device are different, that container in which the liquid is provided with the higher freezing point, in particular water, for introduction is thermally coupled to the refrigerating compartment, and the container in which a second liquid is provided with a low freezing temperature in this regard for introducing, thermally coupled to the freezer.

Especially with a no-frost domestic refrigeration appliance can thus be carried out with a reduced structure of the refrigeration circuit still a very needs-based and independently cooling of the at least two containers. The air duct is laid in such a way that the cold air flowing in the no-frost cooling technology device also reaches the containers and tempered them individually. In addition, this special no-frost concept is then also used to cool the containers individually.

It is preferably provided that the no-frost cooling device has a first air duct, which conducts cold air for cooling to the first container. In particular, it is provided that the no-frost cooling device has a second air duct, which conducts cold air for cooling to the second container.

This also targeted in the respective direction and in the respective volume portion of the housing of the beverage device each required air is passed.

In particular, in a configuration in which the beverage device can be pushed into the housing of the household refrigerating appliance in the horizontal depth direction and pulled out, a non-destructive detachable coupling between the air ducts and the couplings on the housing of the beverage device is formed. In this case, for example coupling units can be provided, in which the respective ends then self-seal during decoupling, so that the outflow of the respective cold air is prevented by the two air channels to the outside. Corresponding coupling units can then also be provided on the housing of the beverage appliance, which are then self-closing or self-sealing when decoupling with the air ducts, so that the temperatures prevailing in each case in the partial volume of the housing of the beverage appliance are not changed undesirably. The respective temperature of the arranged in the sub-volume of the housing of the beverage device container can then be kept relatively low tolerances on their temperatures.

For example, specific coupling flanges can also be provided here, which also enable self-coupling or corresponding decoupling.

For a very fast cooling of the containers, special air ducts around the respective containers are preferably advantageous. Thus, an air-side heat transfer to the containers can be improved by heat transfer intensification in order to achieve a fast and efficient cooling of the containers. Such intensification can be achieved for example by a turbulence generator. In this case, an improved mass transport is achieved by mixing the air. Alternatively, surface enlargements can also be provided, in which case, for example, ribs in an air duct can be provided in thermal contact with a corresponding container. In addition, it can also be provided that an air duct is divided into parallel sub-channels, which then extend into the interior of the container or extend through the container.

It is also possible that at least one Peltier element is present. In particular, such a Peltier element is then with its cold side in thermal contact with the respective container and with its warm side in thermal contact with a corresponding air duct of the no-frost cooling device. Due to the resulting lower temperature on the container and an improved Heat transfer through the Peltier element, the respective liquid can be cooled faster in a container.

In the second container, which is thermally coupled to the freezer, a defrosting device is preferably provided to prevent frost formation in the air duct, which is thermally coupled to the second container, so that here such icing or frost formation can be prevented or very quickly can be defrosted again, and thus a Zueisen this air duct is prevented.

In a further advantageous embodiment, it is provided that the beverage device is mounted on at least two, in particular four rails of the displacement device. This allows a very jerk-free and clamp-free motion control. In addition, just by such a configuration, a relatively heavy beverage device is relatively extensible without any mechanical overuse of the displacement device would occur here.

Preferably, these four rails are arranged at respective corner regions of the four-sided housing of the beverage device, whereby the above-mentioned advantages are further improved and a robust and highly resilient device is formed. Preferably, the rails engage with corner regions or corner edges of the housing of the beverage device, so that a smooth movement is achieved by this exposed guiding on the housing edges and leverage forces can be taken up robustly.

Moreover, it is provided in an advantageous embodiment that the first container has at least one active mixing element for active mixing of the first liquid. Additionally or instead, it can also be provided that the second container has at least one active mixing element for active mixing of the second liquid. An active mixing can be done for example by a representational stirring element in a container. For example, a mechanical stirrer or a magnetic stirrer can be provided here. Also, a circulation of the liquid in the container by means of a pump may be provided.

In a further advantageous embodiment, additionally or instead, it may be provided that the first container has at least one passive mixing element for the passive mixing of the first liquid. Additionally or instead, it can be provided that the second container has at least one passive mixing element for the passive mixing of the second liquid. Examples of passive mixing elements may be specific structuring of an inside of a container. Also, a vortex generator for selectively guiding the thermal convection of a liquid in a container may be a passive mixing element. By a mixing element, a rapid homogeneous temperature control of the entire liquid is achieved in a container.

It is preferably provided that the first container and the second container viewed in the width direction of the household refrigerating appliance are arranged side by side without overlapping or viewed the first container and the second container in the height direction of the household refrigerating appliance superimposed overlapping. By these embodiments, a compact overall construction is achieved, yet simple geometry of the container and in particular simple thermal insulation of the two containers from each other.

It is preferably provided that the beverage device is a mixed beverage generating device which is designed to generate and dispense a mixed beverage mixed from the at least two liquids. Especially for such a configuration, the invention is particularly advantageous, since thus, as already explained above, individual cooling scenarios for the individual containers and thus the respective liquids can take place therein and this can be done independently of each other. The additional benefits have just been mentioned above.

Preferably, it is provided that the first container by a thermal coupling with the cooling compartment to a temperature between 8.0 ° C and 4 ° C, in particular between 0.8 ° C and 1.5 ° C, tempered, and if the first Liquid is contained therein, it can be cooled to an appropriate temperature. In particular, it is provided that the second container is tempered by a thermal coupling with the freezer to a temperature between -8 ° C and -20 ° C, in particular between -13 ° C and -17 ° C. This also makes it possible, in particular if the second liquid is contained in the second container, to cool it to a corresponding temperature.

The exemplary liquids may be water as a first liquid and alcohol or an alcoholic liquid as a second liquid.

In an advantageous manner, it is provided that, viewed in the vertical direction of the household refrigerating appliance, the beverage appliance is arranged between the refrigerating compartment and the freezer compartment, in particular in a receiving area separate therefrom.

As a result, the preferred thermal coupling with the refrigerator compartment and / or the freezer compartment is improved and very short paths with respect to the thermal coupling can be realized. In addition, it is then very user-friendly possible through this position, the beverage device to operate or accessibility without unnatural movements of a user, for example, a too deep bending or a knee, allows.

The terms "top", "bottom", "front", "rear", "horizontal", "vertical", "depth direction", "width direction", "height direction", etc. are the intended use and intended arrangement of the device and at a given then before the device standing and looking in the direction of the device given positions and orientations.

In 1 is a simplified perspective view of a household refrigerator 1 , which is a no-frost household refrigeration appliance, shown in sections. The household refrigerator 1 Here is a fridge-freezer combination. The household refrigerator 1 is designed for storing and preserving food. It includes a housing 2 in which a first inner container 3 is arranged. Walls of the inner container 3 limit a first receiving space for food, this receiving space a refrigerator 4 is.

In addition, the household refrigerator includes 1 another inner container 5 which with its walls delimits a second reception room, a freezer compartment 6 is. The two recording rooms are separated from each other. In the embodiment shown, the receiving spaces in the vertical direction and thus in the height direction (y-direction) are arranged one above the other. They are in the exemplary embodiment preferably closed by not shown, each separate doors, in particular on the housing 2 are hinged hinged.

In addition, the household refrigerator includes 1 a mixed beverage generating device 7 , The mixed drink generating device 7 is in a reception area 8th of the housing 2 arranged. This recording area 8th is separated from the recording rooms. It can be provided that the receiving area 8th is limited by walls of a separate inner container, which is also in the housing 2 is foamed. The recording area 8th However, it can also be integrated in the inner container 3 or the inner container 5 be educated.

In the embodiment, it is provided that the receiving area 8th in the height direction between the cooling compartment 4 and the freezer 6 is arranged.

The mixed drink generating device 7 is front and thus accessible from the front and arranged on the visible side. In particular, it can not be closed by a door at the front and can therefore be covered.

The mixed drink generating device 7 has a housing 9 on.

In the exemplary embodiment it is provided that the housing 9 and thus the entire mixed beverage production device 7 in the depth direction and thus in the horizontal direction, which corresponds to the z-direction, corresponding to a drawer from the receiving area 8th pulled out and pushed back into it. In 1 the fully withdrawn state is shown.

It is preferably provided here that the horizontal displaceability by a displacement device 10 is formed, which has a plurality of bearings. In the exemplary embodiment it is provided that the displacement device 10 comprises at least two, in particular four bearing points. These are formed in the embodiment as rails, which may also be pull-out rails. In particular, here in an upper left corner area a first rail 11 , in the upper right corner area a second rail 12 , in the lower right corner a third rail 13 and in the lower left corner of an in 1 not to be recognized further rail arranged. Through this four-position storage is a very safe and verstreiz- or tilt-safe displacement of the housing 9 allows.

Advantageously, thus, the mixed beverage generating device 7 in the inner container 8th slidably mounted. Advantageously, the displacement device 10 also a pull-out stop, with which in particular as mixed drink-generating device 7 trained beverage device in an in 1 shown fully extended position is secured position. Thus, it can not be overdraw, so that the mixed drink generating device 7 can not fall out or tilt down.

Advantageously, it is also provided that the displacement device 10 a shift safety device, with which the mixed beverage generating device 7 in the fully in the receiving area 8th is arranged secured against reverse securement. This also prevents unwanted slipping out or an existing forward protrusion. An undesirable leakage or dripping of a liquid or a bumping is thereby prevented. This displacement safety can be a locking device. It may be additionally or instead but also provided, for example, a magnetic holder.

Advantageously, on a vertical side wall 14 of the housing 9 an access 15 trained by a flap 16 is closed. After opening the flap 16 can in the interior of the case 9 so as to allow easy and unrestricted access for replacement or filling purposes. It may additionally or instead also be provided that at an opposite further vertical side wall 17 a corresponding access is formed and / or on a ceiling wall 18 of the housing 9 at least one such access 15 is trained.

The mixed drink generating device 7 furthermore includes a parking bay on the front 19 into which a drinking vessel can be adjusted, with which then that of the mixed drink generating device 7 can be collected to be generated and dispensed mixed drink. The mixed drink generating device 7 includes an output unit 20 in particular with a single outlet 21 , It can preferably be provided that for the discharge of each liquid from a container each have their own outlet is present. In addition, it can also be provided that this mixed drink to be produced, which can be produced from at least two different liquids and thus mixed, can additionally be admixed with an additive in powder form or gel form or other liquid form. For this purpose, it may be provided, in particular, that a capsule holder 22 is formed, in which a capsule having said additive can be used. When dispensing the mixed beverage, this ingredient or additive is then removed from the capsule and the mixed beverage in particular before the over the outlet 21 added to the drinking vessel.

In addition, it can be provided in particular that the mixed beverage generating device 7 a capsule storage 23 or a capsule bearing has. In this capsule storage 23 One or more capsules can be stored so that they are always available close to the device itself. In an advantageous embodiment, it can be provided that this capsule storage 23 Is cooled, so that the capsules therein can be stored cooled accordingly.

It is preferably provided that the capsule storage 23 can be opened by a push-push mechanism and then, for example in the form of a sliding bearing in the form of a rail then the capsules received therein free are accessible and can be easily removed from above, for example.

In addition, it can also be provided that the mixed beverage generating device 7 a cartridge for admixing carbon dioxide in the mixed beverage has. In addition the accessibility to the cartridge exchange over at least one existing entrance is 15 allows. In an advantageous embodiment, it is provided that the mixed beverage generating device 7 is connected to a household appliance external water connection, so that a supply of water is possible, for example via a domestic water network. This has the additional advantage that a liquid to be added to the mixed beverage as water is not present in a large-sized container in the mixed-beverage production device 7 must be stored, but that this container can then be dimensioned smaller and can be refilled according to demand and situation adapted. It can then also be provided that such a water supply for producing the mixed beverage does not come from the tank or the container used to hold this liquid in the mixed beverage production device 7 is provided, is supplied, but in addition to or instead also directly from this line to the output unit 20 and thus also to the outlet 21 can be performed.

Thus, especially in the production of hot drinks instead of a cold drink, the energy required for heating is reduced because the initial temperature of the water is higher. Should a carbonation of the mixed beverage then be desired, this can be done by adding carbonated cold water, which is used in the mixed beverage production unit 7 is cooled, or be made possible by a carbonated second liquid, which is then present in the second container, take place.

In particular, it is provided that the mixed beverage generating device 7 a first container, in which then a first liquid having a first freezing point, in particular water, is kept or stored, in order then to provide it as needed for generating and dispensing a mixed beverage. The mixed drink generating device 7 moreover comprises a second container separated therefrom, which is designed to receive a second liquid, which differs from the first liquid, and which has a freezing point different from the first liquid. In particular, the first liquid is water and the second liquid is alcohol, so that the mixed drink may also be an alcoholized mixed beverage.

In an advantageous embodiment, wherein the mixed beverage generating device 7 is designed not only for dispensing a cooled mixed beverage, but also for dispensing a hot beverage, at least one heater is provided. This is preferably close to the outlet 21 attached to minimize heat loss and the least possible heat input to the inside of the household refrigerator 1 to allow. The heater can be the conduit of the outlet 21 to contact. This heater may also preferably be part of an insulation of the capsule mechanism and thus the capsule receptacle 22 represent. To avoid a heat input in the household refrigerator 1 it is advantageous to thermal insulation on the additional heater to the output unit 20 to install. With appropriate thermal insulation, for example, by an airgel, the heat is dissipated mainly to the outside into the environment. Since the heater is only activated for a short time when a corresponding hot drink is to be generated and dispensed, the heat conduction through the lines that lead to the outside is significantly higher than the heat conduction through the insulation to the inside. In addition, it is advantageous if the insulation has a high heat capacity or contains a thermal storage material, for example a phase change material. The waste heat of the heater is preferably buffered in such a configuration in the material, temperature peaks can be reduced and overall the heat input to the inside can be significantly reduced. This thermal storage can with the externally visible surfaces of the output unit 20 be thermally connected. This increases the temperature of these surfaces and a possible condensation of moisture can be prevented.

It may also be provided that lines of outlets 21 in the output unit 20 , which are designed to dispense one or more liquids, are equipped with Peltier elements that allow an active cooling or heating of the lines. If, after the dispensing of a hot beverage by a user, a cold drink is desired, the situation arises that the lines of the dispensing unit 20 can still be warm. The cold water or the cold alcohol from the containers mentioned heat up, so that the finished cold beverage has a higher temperature than desired. This can be counteracted by the Peltier elements since the lines always have the same temperature due to cooling. Thus, it is then achieved that a cold drink or a hot beverage regardless of the temperature of the previous dispensed beverage has the user's desired temperature.

By the respective mentioned cooling possibility of the capsules in the capsule storage 23 Also, the shelf life of the capsules can be prolonged at low temperatures.

Preferably, this is also designed in particular as a drawer capsule storage 23 thermally insulated in the front region, for example with an EPS (expanded polystyrene) component or a PU (polyurethane) component or an airgel component in order to reduce the incidence of heat. As a result, the front side visible surface of the capsule storage 23 be thermally insulated so that no undesirable cold temperatures occur that would be uncomfortable for a user when attacking or touching.

In an advantageous embodiment, it is provided that the mixed beverage generating device 7 also has an ice cube generating and dispensing unit and / or having an ice snow generating and dispensing unit.

Advantageously, it is provided that a seal on the back of a front flange of the housing 9 located and in the inserted state of the mixed drink generating device 7 the recording area 8th separates from the environment.

As in the illustration in 2 can be seen, in this simplified block diagram considered in the height direction interposition of the beverage device 7 between the refrigerator compartment 4 and the freezer 6 shown. It can also be seen here that the beverage device 7 a first container 24 and a separate second container 25 having. The first container 24 is intended to receive a first liquid having its freezing point at a higher temperature than a second liquid entering the second container 25 can be introduced. The first liquid 24 For example, it may be water, whereas the second fluid may be alcohol or an alcoholic fluid.

The two containers 24 . 25 are arranged in the width direction and thus in the x-direction without overlap to each other and arranged in the height direction overlapping each other. As a result, it is possible to achieve a very compact construction, especially in the height direction, and yet a needs-based positioning and maximum volume configuration of the containers 24 and 25 be enabled.

It is especially provided that the two containers 24 and 25 thermally insulated from each other in the beverage device 7 are arranged. This is a thermally insulating partition 26 provided, which is designed here stepped.

The first container 24 is only with the cooling compartment 4 thermally coupled and thus has no thermal coupling with the freezer 6 on. In contrast, the second container 25 only with the freezer 6 thermally coupled, but not with the cooling compartment 4 , By these embodiments, the container 24 and 25 be tempered individually and independently, which in turn has corresponding effects on the liquids introduced therein. For example, the second liquid in the second container 25 be cooled even at temperatures below 0 ° C, without it would freeze. On the other hand, in order to freeze the first liquid in the first container 24 to avoid, this is just with the refrigerator compartment 4 thermally coupled.

In 3 is a representation of the household refrigerator 1 accordingly 2 shown. Different from 2 Here is the arrangement and design of the container 24 and 25 as well as the partition 26 , The containers 24 and 25 extend here essentially over the same width. They are stacked one on top of the other in the vertical direction, but do not overlap in this height direction. On the other hand, they overlap in the width direction at least partially, in particular completely. The partition 26 is here also preferably straight in this sectional view shown and is preferably formed as a flat plate. The thermal coupling of the containers 24 and 25 is according to the embodiment in 2 ,

As in an advantageous embodiment, as they already too 1 was explained, the beverage device 7 Is mounted displaceably in the depth direction, it is then provided in an advantageous embodiment, that a corresponding non-destructive reversible coupling between the housing 9 and a no-frost cooler 34 which is a refrigeration cycle 27 includes, of the household refrigerator 1 is possible.

The no-frost cooler 34 also includes a first air duct for the targeted routing of cool air 32 and a second air channel 33 as exemplified and symbolic in 4 is shown.

To here when decoupling the case 9 Preventing outflow of cold air are the preferred coupling points 28 and 29 on the housing 2 provided with corresponding, not shown, barriers. Accordingly, it is also provided that preferably existing coupling points 30 and 31 on the beverage device 7 are designed accordingly. It may be provided that, for example, the coupling point 28 from the freezer 6 comes from and the coupling point 30 from the separated area in the housing 9 of the beverage device 7 leads, in which the second container 25 is arranged. It can be provided that the coupling point 29 a coupling of the first air channel 32 to the cooling compartment 4 represents and the coupling point 31 in contrast, in a partial region of the housing 9 of the beverage device 7 leads, in which the first container 24 is arranged. In particular, the coupling point 28 a coupling of the second air duct 33 to the freezer 6 dar. The coupling point 30 leads in contrast to a further portion of the housing 9 in which the second container 25 is arranged.

In the embodiment of the household refrigerator 1 as a no-frost refrigeration device are these coupling points 28 and 30 such as 29 and 31 thus according to the refrigerator compartment 4 or from the freezer 6 Coming, with in these no-frost refrigerators accordingly cold air then through these coupling points and the associated lines or air ducts 32 . 33 is directed.

In 5 is the container 24 in a schematic sectional view perpendicular to the longitudinal axis of the container 24 shown. It extends at least one air duct 32 the no-frost cooler 34 in the interior of the container 24 into it. The first air duct 32 Therefore, with the cold air flowing therein, it cools in the first container 24 existing first liquid, especially water. As in 4 can also be seen, is a second air duct 33 the no-frost cooler 34 provided, which is formed with its air flowing therein for cooling the freezer compartment and in the present example, then with the second container 25 is thermally coupled, which is supplied with the cold air and cooled. Here then, for example, be provided that this second air duct 33 in the interior of the container 25 extends into it.

Is the case 9 and thus the entire beverage device 7 not slidably mounted, so the air duct 32 and / or the air duct 33 without interruption in the housing 9 enter and there also without interruption in the respective container 24 respectively. 25 be misplaced. Is, as already explained above, the beverage device 7 relatively displaceable to the housing 2 and thus also to the no-frost cooling device 34 stored, is the air duct 32 as well as the air duct 33 preferably separable, as this via the coupling points or coupling regions 28 and 29 such as 30 and 31 has already been explained. The respective sections of the air ducts, which are then in the respective containers 24 and 25 run, as in the embodiments according to 5 and 6 is shown, can then be arranged fixed therein and be firmly connected, for example, with container walls.

In particular, the household refrigerator is a no-frost domestic refrigeration appliance. A no-frost household refrigerator is equipped with a no-frost technology. As a no-frost technique, a technical process is referred to, in which the humidity is reduced in a designed as a freezer compartment interior. As a result, the food does not frost or significantly reduced and a defrosting of the freezer compartment can be omitted or only needs to be carried out in significantly reduced time cycles. In such a no-frost technique, for example, cooling elements designed as cooling fins and thus a heat exchanger of the secondary circuit lie in a separate area in the interior space. During the cooling phase, the cold air is then introduced from this separated area in the interior and thus the freezer compartment by a fan. These devices are designed so that air circulates through all compartments of the interior and enters the cycle again in the separated area. Since cold air holds less moisture, it precipitates as frost primarily only at the heat exchanger of the secondary refrigeration cycle which is in the separated area and is the coldest point in the no-frost home appliance having contact with air. It may then be provided that a defrost mode is performed at specific time intervals, in which this first heat exchanger is defrosted in the separated area. For this purpose, in particular a heating device is provided in the no-frost domestic refrigeration appliance, by which a heating of this heat exchanger is performed. The resulting then from the thawing ice layer water can run out of the interior and thus also from the device via a gutter and can be collected in a collecting bowl, which can also serve as an evaporation tank. In particular, the fan is deactivated in the defrost mode, so that the freezer compartment remains cooled. Thanks to the no-frost technology, the freezing of cooling fins is significantly reduced and the humidity in the entire domestic refrigeration unit drops, which also significantly reduces the formation of ice layers.

With an exemplary, relatively simple method, the humidity in the freezer compartment is significantly reduced in a no-frost device. This is achieved in particular by a separation of the cooling fins from the actual cooling area or cooling compartment, wherein the cold air is conveyed by means of a fan in the freezer compartment or the freezer compartment. The cold air circulates as a circuit through all compartments of the refrigerator and re-enters the refrigerator section. Since it can absorb the moisture only poorly, and can hold less well, this beats down on the cooling fins. These are heated and defrosted at regular time intervals and the water preferably passes, for example via a channel, into an evaporation container. The humidity in the whole device sinks and almost no ice layers are formed. In contrast to conventional devices, the majority of the resulting moisture accumulates, which leads to Freezing the conventional freezers leads to the household refrigeration unit with no-frost technology in the separate area of the cooling fins.
