Description

The invention relates to an evaporation device for the evaporation of in a built-in refrigerator, in particular a household refrigerator, accumulating defrost water. The invention further relates to a built-in refrigeration device equipped with the evaporation device, in particular domestic refrigeration appliance, and to a method for installing a built-in refrigeration appliance in a niche of a furniture.

A built-in refrigeration appliance is understood to mean a refrigeration appliance which is designed for installation in an installation niche of a piece of furniture. A refrigeration appliance is understood in particular to be a household refrigeration appliance, that is to say a refrigeration appliance used for household purposes or possibly even in the gastronomy sector, and in particular for storing food and / or beverages in household quantities at specific temperatures, such as, for example, a refrigerator, a freezer , a fridge freezer or a wine storage cabinet.

In the interior of refrigerators, such as refrigerators or freezers, created by condensation of humidity on the walls or on a cooling the interior of the refrigerator evaporator defrost water, which must be removed from the interior. This defrost water is collected in an evaporation tank and evaporates into the environment.

Especially with built-in refrigerators, the space available for this evaporation container space is limited. Accordingly, only evaporation tanks with small dimensions and thus small evaporation surfaces can be accommodated in this space. However, this results in only a limited evaporation performance.

The object of the invention is to improve the evaporation performance of evaporation tanks of built-in refrigerators.

This object is achieved with an evaporation device having the features of claim 1.

A built-in refrigerator, which includes this evaporation device, and a method for installing such a built-in refrigeration appliance in a Einbaunische a piece of furniture are the subject of the dependent claims.

Advantageous embodiments of the invention are the subject of the dependent claims.

An evaporation device for evaporating defrosting water accumulating in a built-in refrigeration appliance, in particular a household refrigerating appliance, has an outer evaporation tank and a fluid conduit for directing defrost water from a housing of the built-in refrigeration appliance into the outer evaporation tank, wherein the outer evaporation tank and the fluid conduit are arranged outside the built-in refrigeration appliance (US Pat. hereinafter also referred to as a refrigeration device for short).

Such an evaporation device can thus be easily outside of the housing of the refrigerator and thus outside of an installation niche, in which the housing of a built-in appliance designed as refrigeration device to be installed, are arranged. Thus, the size of the outer evaporation container and thus the evaporation surface and evaporation performance is not dependent on the space that can be provided in the housing or in the installation niche an evaporation container available. The evaporation tank may be located at a completely different location where there is enough space to accommodate a large outer evaporation tank, thus allowing for great evaporation performance. Through the fluid line, the defrost water arising in the refrigeration device is simply diverted into this evaporation container arranged outside.

Preferably, the evaporation device comprises an inner evaporation container formed for placement within the housing, the outer evaporation container and the inner evaporation container being in fluid communication by means of the fluid line.

Thus, advantageously, two evaporation surfaces can be provided, so that the accumulating defrost water in the refrigerator can already be evaporated into the environment and, for example, only defrost water, which exceeds a certain level limit in the inner evaporation container, is discharged into the outer evaporation container to continue there to evaporate.

Advantageously, the inner evaporation container is designed for receiving defrosting water from an interior of the refrigeration appliance. Thus, the defrost water, which is obtained in the interior of the refrigerator, is directed to the inner evaporation container, where it evaporates through a first evaporation surface into the environment. Only when large amounts of defrost water incurred, the defrost water is passed via the fluid line from the inner evaporation tank to the outer evaporation tank, where it then evaporates through a second evaporation surface into the environment.

In an advantageous embodiment, the inner evaporation container has a connection for connecting the fluid line above a maximum fill level. Further advantageously, the fluid line is detachably connected to the connection of the inner evaporation container and / or with a connection designed as a fastening device to the outer evaporation container.

If the connection to the inner evaporation container is arranged relatively high up on the evaporation container, only excess defrosting water advantageously flows into the outer evaporation container. The available first evaporation surface is advantageously utilized to the maximum.

If the fluid line is detachably connected either to the connection to the inner evaporation container or to the connection to the outer evaporation container or to both connections, the outer evaporation container can advantageously be positioned at different locations and then the fluid line can be installed.

Preferably, a second fastening device for the fluid line is provided on the outer evaporation container, which is arranged above the connection designed as a fastening device for connecting the fluid line.

Thus, the fluid line may be attached to the outer evaporation container preferably in two places, so that advantageously a slope can be provided, which ensures that the defrosting water discharged from the inner evaporation container passes largely completely into the volume of the outer evaporation container.

Advantageously, the outer evaporation container has a length of 300 to 500 mm, a width of 300 to 400 mm and a height of 10 to 100 mm. With such dimensions, the outer evaporation tank can be accommodated, for example, in the base area below a standard kitchen cabinet.

The fluid line preferably has a flexible fluid line and / or a hose and / or a plastic molded part. Further advantageously, the total length of the fluid line is between 1.8 m and 2.2 m, in particular between 1.9 m and 2.1 m, and is variable in length in a particularly preferred embodiment.

Thus, the outer evaporation container can be positioned at different locations and easily connected via the flexible fluid line with the housing of the refrigerator or with the inner evaporation container.

If, in addition, in a particularly preferred embodiment, the fluid line is cut to length and / or can be assembled from a plurality of identical sections, the length of the fluid line can be adapted particularly easily to the conditions on site.

It is particularly advantageous if the fluid line has a cross-section that is consistently uniform over its entire length, since the attachment to the connections of the inner and outer evaporation container can thus be carried out without problems even after cutting or lengthening the fluid line sections.

A refrigeration device, in particular a domestic refrigeration appliance, has a housing and an evaporation device described above.

Preferably, the housing is designed for installation in an installation niche in a piece of furniture, in particular in a kitchen furniture. In particularly preferred Embodiment is the outer evaporation container for arranging outside the Einbaunische and further formed an inner evaporation container for placing within the Einbaunische. Advantageously, the outer evaporation container is designed to be arranged in a base area below the kitchen cabinet.

With these refinements, an evaporation tank, which has significantly larger dimensions than conventional evaporation tanks existing in built-in refrigerators, be made available for the evaporation of defrost water. This larger evaporation tank can be easily accommodated outside the housing of the refrigerator. Particularly large dimensions can occupy the evaporation container when it is not only housed outside the housing of the refrigerator, but for example outside of the installation niche in the kitchen furniture in which the refrigerator housing is housed. Visually hidden can be the outer evaporation container, if it is advantageously located below the kitchen furniture in the base area, since it is hidden here over a mounted on the kitchen furniture base board.

In an advantageous embodiment, the outer evaporation container is designed to be arranged in an intermediate region between the installation niche and the base region and / or for arranging in a base region below a second kitchen appliance.

Some kitchen furniture have so-called ventilation gaps in the lower area, in that a niche floor is drawn in between the base area and the installation niche. The outer evaporation tank can also be designed in its dimensions, for example, such that it fits exactly into this ventilation gap. Furthermore, it is also possible to arrange the outer evaporation container under a different kitchen furniture than that in which the refrigeration appliance is placed, so that the base area underneath the built-in refrigeration appliance is advantageously available for other applications.

Advantageously, the housing of the refrigeration device has a door, wherein the connection for connecting the fluid line to the outer evaporation container is to be arranged directed towards the door.

Thus, the outer evaporation container can also be advantageously separated by simply removing a pedestal board from the fluid line to then simply emptying a full outer evaporation container, for example.

Fig. 1 shows a kitchen furniture 10 with a base portion 12 which is disposed on a room wall 14. The kitchen furniture 10 has a front furniture front 16 and in the base area 12, a base board 18 which is offset in the depth direction T of the kitchen cabinet 10 to the furniture front 16. The base board 18 is flush with a bottom 20 and thus covers arranged in the base region 12 feet 22. The kitchen furniture 10 is adjustable over the feet 22 in height. The base board 18 has an opening 24 for ventilation of the base area 12.

Fig. 2 shows the kitchen furniture 10 off Fig. 1 without furniture front 16. In the kitchen furniture 10, a recess 26 is provided for installing a refrigeration device, not shown here. Above the installation niche 26 10 additional compartments 28 are arranged in the kitchen furniture.

Fig. 3 is a side view of the kitchen cabinet 10 off Fig. 1 and Fig. 2 A shows the base height, B the base depth and C the niche depth in the base region 12. The base height A is the distance between the bottom 20 and a lower end 30 of the kitchen furniture 10. The base depth B is The distance between the furniture front 16 and the base board 18. The niche depth C is the distance between the furniture front 16 and the room wall 14. The arrows show the flow of air through the opening 24 in the Base plate 18 in the direction of the room wall 14 in the base region 12. The air can flow vertically upwards and thus serve for cooling components housed in the recess 26, if between the room wall 14 and a Einbaunischen rear wall 32 of the installation niche 26, a gap 34 remains.

Fig. 4 shows an alternative embodiment of the kitchen furniture 10. The kitchen furniture 10 is shown here without furniture front 16, so that the interior of the kitchen cabinet 10 can be seen. Again, 26 compartments 28 are arranged above the installation niche. In addition, between the installation niche 26 and the base region 12, an intermediate region 36 is formed by an intermediate bottom 38 is retracted into the installation niche 26.

Fig. 5 shows the kitchen furniture 10 according to the embodiment in Fig. 4 , which is arranged on a side wall 40. Here, the ventilation of the installation niche 26 does not take place via a gap 34 between the recess rear wall 32 and the room wall 14, but between a side wall 40 and an inner remaining free space 42. To create the remaining space 42, the intermediate bottom 38 and the lower end 30th Thus, the air can flow unhindered through the opening 24 in the base board 18 via the base portion 12 and the remaining free space 42 in the installation niche 26.

The in the Fig. 3 and Fig. 5 shown flowing air can serve both for cooling of components that are housed in the Einbaunische 26, as well as for receiving moisture from the Einbaunische 26. Furthermore, it can also cool and dehumidify components which are arranged in the base region 12 or in the intermediate region 36.

Generally, the in Fig. 3 For example, the base height A is usually between 70 mm to 200 mm variable, as well as the base depth B is usually between 30 mm and 100 mm variable. The ventilation cross section in the base board 18 is about 200 cm ² and has a ventilation grille 43, the altitude and embodiment is also variable. The niche depth C is at least 550 mm, often 560 mm, but also deeper, such as 590 or 610 mm. Usually can not be assumed on both sides of an open passage in the base region 12 side be used because often near-wall positions of the kitchenette. The niche height is device-dependent and over and / or under the actual niche 26 still fans 28 may be located.

The Fig. 6 to Fig. 8 show the arrangement of an evaporation device 44 in the kitchen furniture 10. The evaporation device 44 has an outer evaporation tank 46 and an inner evaporation tank 48. The evaporation tanks 46, 48 are connected to each other via a fluid line 50. The inner evaporation container 48 is disposed within a housing 52 of a refrigerator 54, which is housed in the recess 26 of the kitchen cabinet 10.

The refrigerator 54 has a door 56 for closing an inner space 51 of the housing 52 and a machine room 58, in which a compressor 60 and the inner evaporation container 48 are housed. On a housing rear wall 62, the refrigeration device 54 additionally has a condenser 64.

FIGS. 6, 7 and 8 show various ways that the refrigeration device 54 and the evaporation device 44 may be arranged in the kitchen furniture 10.

In a first embodiment, shown in FIG Fig. 6 , the refrigerator 54 sits directly on the lower end 30 of the kitchen cabinet 10. The outer evaporation container 46 is arranged in the base region 12 of the kitchen cabinet 10. Via the fluid line 50 defrosting water 66 is discharged from the inner evaporation tank 48 to the outer evaporation tank 46. Since the inner evaporation tank 48 is disposed on the compressor 60, heat discharged from the compressor 60 can be directly utilized for the evaporation of defrost water 66 trapped in the inner evaporation tank 48. In order to make maximum use of this heat, a connection 68 for the fluid line 50 is arranged on the inner evaporation container 48 at an upper edge 70, which simultaneously serves as fastening means 71. Thus, defrost water 66 is transferred into the outer evaporation tank 46 only when a maximum level F _max in the inner evaporation tank 48 is reached and the amount of heat released from the compressor 60 is no longer sufficient to evaporate the collected defrost water 66 into the environment.

The outer evaporation container 46 has, in addition to the connection 68, a second fastening device 72, which ensures that a gradient in the fluid line 50 from the second fastening device 72 to the connection 68 results, so that the defrosting water 66 discharged from the inner evaporation container 48 becomes is not jammed in the fluid line 50, but is introduced directly into the outer evaporation tank 46. The port 68 on the outer evaporation tank 46 is located immediately behind the base board 18, so that it is accessible upon removal of the base board 18. The fluid conduit 50 is additionally releasably connected to the port 68 on the outer evaporation container 46 so that it can be easily removed from the outer evaporation container 46 to remove the outer evaporation container 46 for emptying out of the base portion 12.

The arrows in Fig. 6 indicate the direction of the airflow. The air initially flows into the base area 12 via the opening 24 in the base board 18 and then flows over the surface of the defrosting water 66 located in the outer evaporation tank 46. In the process, this defrost water 66 evaporates and is transported by the air flow. The air now continues to flow along the engine room 58 where it entrains warm moist air from the engine room 58 and then via the condenser 64, cooling the condenser 64.

In Fig. 7 a second embodiment is shown how the refrigeration device 54 and the evaporation device 44 can be arranged in the kitchen furniture 10. Here is the outer evaporation container 46 in the intermediate region 36 between the lower end 30 of the kitchen cabinet 10 and the intermediate bottom 38 between the Einbaunische 26 and the lower end 30. In the lower end 30 a vent 74 is recessed, so that air in the intermediate area 36 can flow. The arrangement of the refrigeration device 54 relative to the outer evaporation container 46 is significantly narrower than in the embodiment according to Fig. 6 , Therefore, it is advantageous if the fluid line 50 is a flexible fluid line 76 and thus can be strongly curved. In the case shown, the fluid conduit 50 is a tube 78. The air flow is directed, as indicated by the arrows, through the ventilation opening 74 in the intermediate region 36, via the outer evaporation container 46, along the engine room 58 and via the condenser 64.

Fig. 8 shows a third embodiment of how the refrigerator 54 and the evaporator 44 may be housed in the kitchen furniture 10. Here, the refrigeration device 54 is in an elevated position above a lower cabinet 80. In order to be able to pass the excess defrosting water 66 from the inner evaporation container 48 to the outer evaporation container 46 via the fluid line 50, the fluid line 50 must be longer in the shown embodiment than at according to the embodiments Fig. 6 and Fig. 7 , Thus, all three embodiments can be realized, it is therefore advantageous if the fluid line 50 from the beginning has a total length of about 1.9 m to 2.1 m, but can be shortened to shorter overall lengths. This can be ensured, for example, that the fluid line 50 is simply cut to length, ie it is simply cut to the desired length. Therefore, if possible, it has a continuous cross-section, so that the newly created by the cutting ends can be easily connected to the terminals 68. Alternatively, it can also be modularly constructed from identical sections.

Will that be in Fig. 6 to Fig. 8 shown refrigeration device 10 is now installed in the respective installation niche 26, the outer evaporation tank 46 is not initially in communication with the inner evaporation tank 48. First of all, the fluid line 50 is fastened only to the inner evaporation container 48, and then the refrigeration device 54 is introduced into the installation niche 26. The fluid line 50 is then guided via the gap 34 to the base region 12. Depending on the embodiment, the length of the fluid line 50 is adapted to the situation on site and then connected to the port 68 of the outer evaporation tank 46. Finally, the fluid conduit 50 is still attached to the second attachment 72 to create a slope in the fluid conduit 50. The outer evaporation container is positioned in the base region 12 or in the intermediate region 36 and then the base board 18 is fastened.

The defrost water 66 produced during the operation of refrigerators 54 is frequently collected in an evaporation tank 48, which is usually located in one area of the unit (machine room 58), often above the compressor 60. The defrost water 66 collected therein evaporates, favored by the heat of the compressor 60.

With the permanent increase in the efficiency of refrigerators 54 is increasingly the problem that no longer sufficient heat from the compressor 60 is discharged to evaporate the defrost 66 reliably. If parallel attempts are made to adapt the characteristics of the refrigeration appliances 54 to humid climatic conditions, which ultimately leads to a larger amount of defrosting water, the question arises of improved technical solutions.

At the same time, the available installation space for enlarging the evaporation tank 48 is restricted, in particular for built-in refrigeration appliances.

• Kältegeräte 54 mit Verdunstungsbehältern 48, die oberhalb des Verdichters 60 angeordnet sind.
• Kältegeräte 54 mit Verdunstungsbehältern 48, die nicht oberhalb des Verdichters 60 angeordnet sind, aber in denen oder an denen gegebenenfalls andere wärmeerzeugende Komponenten, z.B. Kompaktverflüssiger, angeordnet sind.
• Kältegeräte 54, durch deren Verdunstungsbehälter 48 ein druckseitiges Kältemittelrohr führt, das Verflüssigerrohr.
• Kältegeräte 54 mit kaskadenartigen Wasserableitsystemen zur Vergrößerung der Oberfläche für die Verdunstung des Abtauwassers 66.
• Kältegeräte 54 mit definierten Anforderungen an Be- und Entlüftungsquerschnitte zur Kühlung des Aggregats (Verdichter 60, Verflüssiger 64, andere Komponenten), denn neben der von dem Abtauwasser 66 aufgenommenen Wärme beeinflusst die verfügbare Oberfläche die Verdunstungsleistung maßgeblich. Weiter beeinflusst auch eine Luftbewegung die Verdunstungsleistung positiv.
• Kältegeräte 54, deren Aggregatbelüftung durch natürliche Konvektion erreicht wird.
• Kältegeräte 54, deren Aggregatsbelüftung ganz oder teilweise durch einen Ventilator erfolgt.

Investigations show that even the following improvement measures do not lead to the required evaporation performance:

• Refrigerating appliances 54 with evaporation containers 48, which are arranged above the compressor 60.
• Refrigeration appliances 54 with evaporation tanks 48, which are not arranged above the compressor 60, but in which or on which optionally other heat-generating components, such as compact liquefier, are arranged.
• Refrigeration appliances 54, through whose evaporation tank 48 a pressure-side refrigerant pipe leads, the condenser tube.
• Refrigerating appliances 54 with cascade-like water discharge systems for increasing the surface for the evaporation of defrost water 66.
• Refrigeration appliances 54 with defined requirements for ventilation cross-sections for cooling the unit (compressor 60, condenser 64, other components), because in addition to the heat absorbed by the defrost 66, the available surface significantly affects the evaporation performance. Furthermore, an air movement also positively influences the evaporation performance.
• Refrigeration appliances 54, whose aggregate ventilation is achieved by natural convection.
• Refrigeration appliances 54, the aggregate ventilation is wholly or partly by a fan.

The aim is to find another measure to improve the evaporation performance of built-in refrigeration appliances. If appropriate, the measure should be able to be combined with the other measures mentioned above with as little If necessary, expenses can only be introduced with defined device variants and, if necessary, can also be retrofitted in case of customer service. Furthermore, the measure should be cost-effective and have a low quality risk, generate no additional energy intake, be non-approbationrelevant and work in all significant cases.

The simplest and least expensive variant for increasing the evaporation capacity is to maximize the size of the evaporation tank 48 by making it as large as possible within the available construction space. Alternatively, in order to increase the evaporation performance in the embodiments described above, a second outer evaporation tank 46 is placed in a different location such that it is possible to defrost water 66 from a certain maximum level F _{max of} the first inner evaporation tank 48 into this second, outer evaporation tank 46 to pass over.

For built-in appliances, the available space for the design of the entire refrigerator 54 is predetermined and limited by the installation niche 26. In order to place a larger evaporation tank 48 in the engine room 58, this would have to be made larger, which would always have to be done at the expense of the useful volume of the device. The same applies to the application of a second evaporation container below the device housing 52. In contrast to solo-standing devices, it is in the design of built-in appliances designed to make the space between the bottom of the device body and the top of the Einbaunischenbodens as small as possible, so the device body and thus to keep the useful volume as large as possible. For built-in appliances, this is possible because the ventilation of the unit, i. the compressor 60 and the condenser 64, takes place on the kitchen furniture base and no ventilation gap is necessary directly below the device body.

The present embodiments now take up the possibility of placing a second, outer evaporation container 46 in the base region 12 of the kitchen cabinet 10 and a suitable connection between the primary, inner evaporation container 48 in the machine room 58 of the device, eg above the compressor 60, and this secondary, to create outer evaporation tank 46. The space in the base region 12 of the installation niche 26 provides all the necessary conditions to be able to apply an external evaporation container 46 in a suitable form. Because the area is basically ventilated, since this is a requirement of the refrigerator 54 anyway. Through this ventilation, both natural convection and forced ventilation systems, the evaporation is favored.

Next, the area offers considerable space, so that an outer evaporation container 46 can be applied with a large surface area. Preferably, the size of the evaporation container is selected to be compatible with the known kitchen furniture designs. Based on the known distances of the furniture base feet 22 different manufacturers, this results in a meaningful maximum size of about 350 mm wide x 400 mm depth. Larger outer evaporation tanks 46 may not be installed in any case, as this would otherwise result in collisions with the known furniture feet 22 and / or the base board 18. On the other hand, smaller external evaporation tanks 46 result in restrictions on the maximum evaporation capacity.

The evaporation container height could be selected at about 50 mm high with a pure design to the application in the classic base area 12. However, there are installation cases with so-called indirect ventilation, in which the air supply between the niche floor and a retracted intermediate floor 38 takes place. This ventilation gap is often reduced to a minimum by the kitchen furniture manufacturers, so that only the minimum ventilation required for the built-in appliance is guaranteed. Often clear height of this gap of less than 35 mm can be found.

Thus, even in such a case, the outer evaporation container 46 can be installed at this point and the ventilation section is not completely closed, a height of the outer evaporation container 46 is provided by less than 20 mm. This results in meaningful maximum height dimensions of the second, outer evaporation container 46 of 20 mm height x 350 mm width x 400 mm depth.

Since the relative position of the refrigerator 54 to the base portion 12 of the kitchen cabinet 10 is not known due to the many different installation cases, preferably a flexible connection line to the outer evaporation container 46 is provided. In Particularly preferred embodiment, a hose 78 is suitable to establish the connection between the two evaporation tanks 46, 48. The tube 78 is preferably designed such that a wide variety of connection lengths, depending on the individual installation situation, can be generated. This can be done, for example, by the connection geometries are designed to at least one of the two evaporation tanks 46, 48 so that a hose 78 with a constant cross-section can be shortened simply by cutting to length, such as cutting, sawing or breaking, and the hose end thus produced again the evaporation tank connection geometry fits.

Another possibility is to build the tube 78 from individual identical sections, which together give the necessary total length.

The port 68 on the second outer evaporation container 46 is preferably to be provided on the front of the outer evaporation container 46 so that the user is easily able to detach the outer evaporation container 46 from the hose 78 when installed, e.g. for cleaning purposes or for disassembly of the entire device. By dismantling the base board 18, this is then anytime easily possible. By contrast, if the connection geometry is arranged at the rear, the hose 78 can only be reached with difficulty.

The overall length of the hose 78 should preferably be independent of the design of the hose 78, i. whether it is a hose 78 which can be cut to length or a hose 78 which can be joined together from partial segments, which overcome the height difference between the two evaporation tanks 46, 48. Based on the most extreme installation cases, this is a height difference of about 1.50 m and 400 mm connection length to the outer evaporation tank 46. Accordingly, it is advantageous to provide a hose 78 in a length of about 1.9 m to 2.1 m.

In designing the connection geometry to the outer evaporation container 46, a second, higher attachment point to the outer evaporation container 46 is advantageous to provide a drainage gradient.

4. 4. The second, outer evaporation container 46 is applied in the base region 12 and the hose 78 is attached to the connections 68.
5. 5. An excess length of the hose 78 is shortened.

Before dismantling the refrigeration device 54, the hose 78 is preferably released from the second, outer evaporation container 46.

The use of an additional, external evaporation tank 46 is significantly less expensive than other known solutions to increase the evaporation performance and can be applied by this invention in built-in appliances that offer no space in the device area for this purpose.

The evaporation performance can be significantly increased by means of a second, outer evaporation container 46, without this space being negatively affected in the device area and thus in the useful volume.

The otherwise unused space of the furniture base is used to increase the evaporation capacity.

The ventilation taking place through the base area 12 is used for optimal evaporation. The evaporation in the base area 12 works both with ventilation with static convection and with forced ventilation systems. The solution is adaptively possible, ie a device can be improved by merely adding the components to the kit with regard to the evaporation performance.

The solution can be used as a customer service solution. The solution works by the sufficiently long provided and adjustable in length connection hose line in all imaginable installation cases.

Thus, an increase in the evaporation performance of the built-in refrigerator can be achieved by a downstream outer evaporation tank 46, which is not in the installation area of the refrigerator 54, i. the evaporation container 46 is not arranged in the machine room 58 and not directly below the device body. Rather, it is located in the base area 12 of the kitchen cabinet 10. Alternatively, it can also be located in the base area 12 of a neighboring piece of furniture of the installation niche 26. Further alternatively, it may not be located in the kitchen base 12, but in an intermediate area 36 above the base area 12 but below the nest 26, e.g. in a furniture compartment or a separate base cabinet or a ventilation gap.

Preferably, the envelope dimensions of the outer evaporation container 46 in any dimension are substantially greater than 25 mm high x 400 mm wide x 400 mm deep, and preferably not significantly smaller than 25 mm high x 400 mm wide x 400 mm deep. It is advantageous if a flexible and / or adaptable water-length-conducting connecting element, for example a drain hose or a connecting hose, is arranged between the two evaporation tanks 46, 48. In one embodiment, the tube 78 can be shortened in length and then advantageously has a constant cross section, so that the shortened tube 78 also has an unchanged connection cross section to at least one of the evaporation containers 46, 48. The hose 78 may alternatively have a plurality of identical sections, which are lined up in any number and thus always provide constant connection cross-sections of the evaporation container 46, 48 available. Preferably, the entire tube 78 in its unabridged initial length is about 1.9 m to 2.1 m long. In the embodiment shown, the connection 68 on the inner evaporation container 48 is configured such that an overflow into the outer evaporation container 46 does not occur until a defined maximum fill level F _{max is} exceeded. As in the Fig. 6 to Fig. 8 As shown, the outer evaporation container 46 has a second attachment means 72 for the tube 78, so that a discharge slope can be provided at the tube end. The hose 78 is in the illustrated embodiments from the front through the base portion 12th accessible area of the outer evaporation tank 46 attached. The hose 78 is also releasably connected to the two evaporation tanks 46,48. Alternatively, instead of a hose 78, a plastic molding, for example an extrusion, injection molding or blow molding, can be used.
