Description

Technical area

The invention relates to a refrigeration device with superposed refrigerated drawers.

Refrigeration appliances with two or more superimposed refrigerated drawers for domestic and commercial use are known from the prior art. The refrigerated drawers have an upwardly open shell, which is formed by a rear wall, a front wall opposite the rear wall, two opposing side walls and a bottom connecting all walls. The refrigerated drawers are extendable stored in a support structure or a housing of the refrigerator and can be easily managed from above, that is, they can be easily filled from above with refrigerated goods and the refrigerated goods can also be easily removed through the upper opening of the refrigerated drawer again.

State of the art

An example of such a refrigeration device is in WO 2007/036736 A1 disclosed. It includes refrigerated drawers with trays whose shell walls - including the bottom of the bowl - are well insulated. The shell walls have upper edges that define the shell opening. Each refrigerated drawer is associated with an insulated lid, which cooperates with the upper edges of the shell walls thermally insulating in the closed state of the refrigerated drawer and closes the refrigerated drawer tightly against the environment. Cover and refrigerated drawer together form a refrigeration unit. The refrigeration device comprises a plurality of refrigeration units, which are arranged one above the other in a housing. The lids are firmly anchored in the housing; the refrigerated drawers are mounted extendable below their respective lid in the housing. Between the individual refrigeration units, more precisely between the bottom of an upper refrigeration drawer and the lid of an underlying refrigerated drawer is an air gap, which is open even when the refrigerated drawer is closed against the environment. That means the air gap permanently in contact with warm moist ambient air. The moisture from the ambient air condenses on the cold surfaces of the bottom and lid. It comes to condensation and / or ice and snow. This problem is encountered in WO 2007/036736 A1 by active ventilation of the air gap, preferably with warm air, but this degrades energy efficiency.

A very similar refrigeration device is in WO 2007 / 010267A2 disclosed. Even with this device, there is an air gap between the refrigeration units. The risk of condensation and the formation of snow in the air gap is counteracted by the fact that the air gap is closed on all sides by seals with closed refrigerated drawer. This improves energy efficiency, since the active circulation of warm air can be dispensed with. In addition, can be dispensed with insulation of the bottom of the upper drawer, whereby usable cooling volume is obtained. By the measure taken, the air gap is no longer accessible for wet ambient air when the refrigerated drawer is closed, but when opening the drawer, the cold outer surface of the bottom of the refrigerated drawer is still in contact with the warm moist ambient air and brings this at least partially when closing the drawer also in the air gap with. As already in WO 2007/010267 A2 even described, can be reduced by the described sealing of the air gap condensation or condensation and ice and snow formation in the air gap, but they can not quite eliminate. The trapped air in the air gap can also lead to unpleasant odors.

Presentation of the invention

Object of the present invention is to provide a refrigeration device with superimposed refrigerated drawers, which shows no condensation and / or ice and snow formation between an upper and a lower refrigeration drawer.

The object is achieved by a cooling device with the features according to claim 1.

The refrigerator according to the invention comprises superimposed refrigerated drawers, which are formed open at the top, and a support structure in which the refrigerated drawers are movably mounted between a closed and an open state. In addition, the refrigeration device comprises a refrigeration compartment, which serves to receive an upper refrigeration drawer and which is closed when closing the upper refrigeration drawer frontally by a front wall of the upper refrigeration drawer, and a lid which is associated with a arranged under the upper refrigeration drawer lower refrigeration drawer and the closed Condition of the lower refrigeration drawer closes it at the top. Furthermore, the refrigeration device comprises a stationary in the support structure arranged intermediate bottom, which extends between the two refrigeration drawers and is formed on its underside as a lid for the lower refrigeration drawer and on its upper side as a shelf of the refrigeration compartment for the upper refrigeration drawer. Due to this inventive design of the refrigeration device, the refrigerated drawers can be arranged one above the other without an air gap exists between them, the standing air contained or would be susceptible to condensation / condensation or ice and snow formation. The active circulation of air and especially warm air can be dispensed with, which increases the energy efficiency.

In a first embodiment, the intermediate bottom of the refrigeration device is part of the support structure. This simplifies manufacture and reduces assembly time.

In another embodiment, the intermediate bottom of the refrigeration device is a separate component which is anchored in the support structure. In a corresponding embodiment of the support structure, this can increase the flexibility with respect to the design of the refrigeration device. The lower refrigeration drawer can be provided, for example, at different heights of the refrigerating appliance and / or the height of the refrigerating compartment for the upper refrigerating drawer can be varied.

For both embodiments, it is advantageous to design the intermediate floor insulated, so that temperature differences between the upper and lower refrigeration drawer remain without consequences and both cold drawers in the closed state with respect to the ambient air are thermally and well shielded and insulated with respect to moisture. In this variant of the two embodiments, it is possible, for example, a cold drawer as Cooling drawer and the other refrigerated drawer form as a freezer drawer, without the temperatures for the individual refrigeration drawers must be continuously readjusted. It is irrelevant whether the upper or the lower refrigeration drawer is designed as a freezer drawer, both is possible. However, it is also possible to design both refrigerated drawers as freezer drawers or both refrigerated drawers as refrigerated drawers with deliberately different temperatures for different frozen goods or refrigerated goods (finished products, fruit / vegetables, meat).

As already mentioned, the upper refrigeration drawer is advantageously stored in a refrigeration compartment, wherein the refrigeration compartment has a compartment opening at the front, bounded by compartment walls which together with their free end sides form a frame around the compartment opening. When the upper refrigerating drawer is closed, the frame cooperates with an insulated front wall of the upper refrigerating drawer in such a way that the refrigerating compartment in which the upper refrigerating drawer is stored is thermally sealed.

For this purpose, in one embodiment, a thermal seal is provided between the frame of the compartment opening and the front wall of the refrigerated drawer. In a first variant of this embodiment of the refrigeration device, the seal is fixed on the frame. As a result, the seal is better protected against damage when operating the refrigerated drawer. In a second variant, the seal is fixed on an inner side of the insulated front wall of the upper refrigeration drawer. Regardless of where the seal is attached, it can be glued or incorporated, for example, in a designated groove.

The sealing plane between the refrigerating compartment and the upper refrigerating drawer is oriented more or less vertically independently of the individual configuration in this embodiment.

The upper refrigeration drawer advantageously has a shell, the shell walls and the shell bottom are uninsulated and which is firmly connected to the insulated front wall of the refrigerated drawer. The shell may for example be hung in the front wall of the drawer or glued to it; it may be screwed on or fastened to the front wall with the aid of a snap connection, this listing not being exhaustive, but only a few possible examples shows. In all these connection possibilities necessary for the connection connecting members may be provided on the front wall and / or on the shell. They may be designed such that they allow a desired positioning of the shell with respect to height and possibly also with respect to lateral adjustment. The shell walls and possibly also the shell bottom are not insulated and configured either as a closed thin walls or as a basket-like openwork walls.

However, in special circumstances, for example in the case of particularly large temperature differences between ambient air and temperature, it may be advantageous to provide the bottom and / or walls of the shell of the upper refrigeration drawer with insulation.

In a further embodiment, the lower refrigeration drawer is insulated on all sides. Such configured refrigeration device has a high energy efficiency, since no temperature equalization between environment and content of the refrigerated drawer can take place on the isolated walls of the refrigerated drawer. For this reason, in such an embodiment of the refrigeration appliance according to the invention, those parts of the support structure which laterally surround the lower refrigeration drawer can be designed without insulation. If the bottom of the lower refrigerating drawer is also insulated, then the bottom of the supporting structure can also be designed with little or no insulation, or the supporting structure can be designed without any bottom. All these measures save volume, which is available to the consumer in this way as a usable cooling volume.

If such a configured lower refrigeration drawer with an insulated lid of the type described above is closed from above, this is particularly efficient both in terms of energy consumption and in terms of volume, since the lid is indeed an integral part of the false bottom or the shelf.

It is advantageous in this embodiment, when a seal is provided between the lid and the lower refrigeration drawer. The seal can be provided both on the refrigerated drawer and on the lid or on both.

In a further embodiment, the lid of the lower refrigeration drawer has a lower edge, hereinafter referred to as the lower edge, and the lower refrigeration drawer has an upper edge, hereinafter referred to as the upper edge, which is formed by free end faces of those walls which the upper opening of Limit open top of cold drawer. The lower edge of the lid and the upper edge of the lower refrigeration drawer are designed such that they cooperate when closing the lower refrigeration drawer and close thermally tight.

In the following, the plane of extension is understood to mean the plane along which the lower refrigerating drawer is moved during opening and closing. If the lower edges of the lid and the upper edges of the lower refrigeration drawer run in a more or less horizontal plane or in a plane which is more or less parallel to the plane of extension, this is very favorable in terms of energy efficiency. When the lower cold drawer is pulled out, hardly any ambient air can then penetrate into the region of the support structure belonging to the lower cold drawer.

In a further embodiment, the lower edge of the lid extends obliquely from the front top to the rear bottom, wherein the upper edge of the associated lower refrigeration drawer at the same angle is inclined, so that the edges of the lid and refrigerated drawer engage wedge-shaped when closing and close thermally tight. In this way, the appreciable resistance, which otherwise when moving the cold drawer through the adjacent edges of the lid and drawer or the friction of the seal on the opposite edge or the opposite cooperating with this seal, on the first moment of opening or the last moment to be reduced. This results in an easier mobility of the lower refrigeration drawer and a more comfortable handling for the user.

In an advantageous development of this embodiment, the lower refrigeration drawer is advantageously provided with its lower side upper edge lying with an inner container having a horizontally extending upper edge of the container. This ensures that even in the back of the refrigerated drawer stored refrigerated goods can not fall beyond lower upper edge of the refrigerated drawer. The volume of the drawer is fully usable in this way without danger.

In an advantageous development of all these embodiments, a seal is provided between the upper edge of the lower refrigeration drawer and the lower edge of the lid. This can either be fixed to the upper edge of the drawer or the lower edge of the lid, for example by gluing, insertion into a groove provided for this purpose, screwing a groove strip into which the seal is or will be introduced etc. Seals can also be provided on both edges be, which cooperate sealingly when closing.

In a further embodiment, the lower refrigeration drawer is arranged adjacent to the base space. In such a case, the support structure can advantageously be designed without a bottom, so that it is possible to benefit from circulating air in the base space and / or from warm exhaust air from units arranged in the base space. The base space is a common place for the accommodation of necessary for the operation of the refrigerator units.

In a variant of this embodiment, the refrigeration device is configured such that, in the closed state, part of the lower refrigeration drawer is located in the base space. This increases the usable volume for the user of the refrigerated drawer.

It is advantageous in a development of this embodiment, a ventilation grille extendable connected to the refrigerated drawer.

Further refinements and advantageous variants are the subject of dependent claims or are illustrated and / or described with reference to the figures.

Ways to carry out the invention

In FIG. 1 a refrigeration device 10 is shown with a support structure 22 in which two refrigeration drawers 11, 13 are arranged one above the other. The refrigerated drawers 11, 13 are movably mounted on extensions 7 between a closed state (shown here) and an open state (not shown) in the support structure 22. The extracts 7 are indicated by dashed lines.

The refrigeration device 10 includes a refrigerating compartment 50 for receiving the upper refrigerating drawer 11, the two superimposed refrigerating drawers 11, 13 and a stationary intermediate floor 44. The intermediate bottom 44 is located between the two refrigerated drawers 11, 13 and in this example is part of the support structure 22. The intermediate bottom 44 is insulated and formed on its upper side as a shelf 52 of the refrigeration compartment 50. On its underside, the intermediate bottom 44 is formed as a lid 46 which closes the lower refrigerant drawer 13 from above.

The refrigeration compartment 50 for the upper refrigeration drawer 11 comprises a compartment ceiling 54 opposite the compartment floor 52, a compartment rear wall 58 and two opposite compartment side walls 56. Of the compartment side walls 56, only the rear one can be seen in this illustration. The shelf 52, the side walls 56 and the compartment cover 54 each have a free end face, which is aligned against a front side 20 of the refrigerator 10 and together form a frame 60 to a compartment opening 62 through which the upper refrigeration drawer 11 in the refrigeration compartment 50th is introduced. The frame 60 cooperates with the upper refrigerated drawer 11 closed with an insulated front wall 64 of the upper refrigerating drawer 11 such that the compartment opening 62 is thermally sealed. For this purpose, a seal 68 is provided between frame 60 and front wall 64. In this embodiment, the seal 68 is mounted on the front side of the frame 60. The sealing plane formed by the seal 68 extends in principle vertically. In principle, in this case means that there may be deviations due to tolerances or due to a particular embodiment of the interface between front wall 64 and frame 60 (for example with a step or bevel).

The walls 52, 54, 56, 58 of the refrigerating compartment 50 are thermally insulated in this embodiment. The extracts 7, over which the upper refrigeration drawer 11 is slidably mounted, are arranged on the inside of the compartment side walls 56.

For storage of refrigerated goods, the upper cold drawer 11 is provided with a shell 66 whose shell walls and the bottom of the shell are not insulated, resulting in a larger usable cooling volume and 50 is not necessary due to the good insulation of the refrigeration compartment. In this particular example, the shell walls are designed like a basket. The shell 66 is fixedly connected to the front wall 64 and designed in this embodiment as a separate component which is hooked via a snap connection in the front wall 64.

The result of the construction described here is that the uninsulated shell 66 of the upper refrigeration drawer 11 is stored behind the thermally insulated front wall 64 of the refrigerated drawer 11 in a cold compartment 50 thermally insulated against the outside.

The lower refrigeration drawer 13 has an insulated bottom 90, an insulated front 92, an insulated rear 94 and insulated sidewalls 96, of which latter only the rear one can be seen in this illustration. The front side 92, the rear wall 94 and the side walls 96 have upwardly directed free end faces which together form an upper edge 98 of the lower refrigerant drawer 13 and laterally delimit an upper opening 99 of the lower refrigeration drawer 13. When closed, the upper opening 99 of the likewise insulated lid 46, which is part of the intermediate bottom 44, thermally sealed from above.

For this purpose, a seal 48 is provided between the cover 46 and the upper edge 98 of the lower refrigeration drawer 13, which is fixed in this example at the upper edge 98 of the refrigerated drawer 13. Due to the good insulation of the lower refrigeration drawer, the support structure is only slightly or not insulated in that region 24 in which it laterally surrounds the lower refrigeration drawer 13. In the example shown here, it also has no bottom.

The support structure 22 is covered with a worktop 3 and supported on a base 12 which defines a socket space 14 with a base height Hs. The refrigeration device 10 comprises an appliance front 20, which is covered with front panels 5. The front panels 5 protrude on all sides beyond the front elements 92, 64 of the drawers 11, 13 and obscure insulation and parts of the support structure 22, so that the observer a pleasing sight of the front side 20 of the refrigerator 10 results. The base 12 comprises at the front a plinth panel 16 with a ventilation grille 42, which is arranged offset from the front of the device 20, whereby a base recess 30 is defined with the depth T1. The ventilation grille 42 is placed in a ventilation duct 40, which serves to ventilate the base space. The ventilation grille 42 protects the base space 14 against contamination. The lower refrigeration drawer 13 is with its flat bottom 90 so on the extracts 7 in the Supported structure 22 that it can be easily moved over the base panel 16 with its ventilation grille 42 away. The base 12 is not part of the refrigeration device 10 in this embodiment, but a separate component that belongs for example to a fitted kitchen (not shown), in which the refrigerator is fitted. Likewise, the front panels 5 are tuned to the appearance of other built-in elements of the kitchen.

FIG. 2 shows a second embodiment of the refrigerator 10 according to the invention in an analogous sectional view FIG. 1 , The refrigeration device 10 shown essentially corresponds to that FIG. 1 , The refrigeration appliance 10 comprises an appliance front 20, which, as customary in fitted kitchens, is covered with a furniture front 5. The furniture front 5 protrudes down beyond the front of the device 20. The base 12 comprises at the front a plinth panel 16, which is arranged set back relative to the front panel 20 and whose upper edge 18 is at a lower height than the base height Hs. In this way, the base panel 16 and front panel 20 form a recess 30 with a depth T1.

This embodiment is different from that FIG. 1 in that the intermediate bottom 44 is a separate component, which is anchored in the support structure 22 in a stationary manner, this being possible in this embodiment at different heights in the support structure 22. This design increases the flexibility with respect to the design of the refrigeration device 10, for example, in the same support structure 22 upper refrigeration drawers 11 can be introduced with different heights and / or the lower refrigeration drawer 13 may be provided at different heights in the support structure 22. Also for the lower refrigeration drawer 13 different heights can be provided in this way without major structural measures.

The intermediate bottom 44 is in turn well insulated and acts against the top as a shelf 52 for the refrigeration compartment 50 of the upper refrigeration drawer 11 and down as a lid 46 relative to the lower refrigeration drawer 13. The provided between the lid 46 and the upper edge 98 of the lower refrigeration drawer 13 seal 48th is fixed in this example on the cover 46, whereby the seal is well protected from damage. The seal 68 between the frame 60 and the front wall 64 is attached to the inside of the front wall 64 in this example.

The base 12 is part of the refrigeration device 10 and in the base space 14, the units are housed for the operation of the refrigerator. This increases the usable volume. The ventilation duct 40 is not provided here with a ventilation grille.

Even if the base 12 does not belong to the refrigerator (unlike in FIG. 1 ), it can of course still be used to accommodate 14 base units of the refrigerator in the base space and so to optimize the usable volume of the device.

FIG. 3 shows in analogous representation to the FIGS. 1 and 2 a third embodiment of the refrigeration device 10 according to the invention, that of FIG. 1 is similar again. The intermediate bottom 44 is in turn part of the support structure 22 and forms against the top of the shelf 52 for the refrigeration compartment 50 of the upper refrigeration drawer 11 and against the bottom lid 46 for closing the lower refrigerant drawer 13. In contrast to FIG. 1 extends the upper edge 98 of the lower refrigeration drawer 13 in this embodiment obliquely from the top to the bottom rear, so that the upper edge of the back 94 is lower than the upper edge of the front side 92 of the lower refrigeration drawer 13. The lid 46 is fittingly with an equal angle provided obliquely extending lower edge, so that the oblique edges 72 of the refrigerated drawer 13 and lid 46 engage in a wedge shape when closing the lower refrigeration drawer.

Between the upper edge 98 of the cold drawer 13 and the lower edge 72 of the lid 46, in turn, a sealing means 48 is provided, which ensures a secure seal against the ambient air in the closed state of the lower refrigerant drawer 13. For the tightness, it does not matter whether the sealant 48 is attached to the lower edge 72 of the lid 46 or the upper edge 98 of the cold drawer 13. An attachment to the lower edge 72 of the lid 46, however, reduces the risk of damaging the seal 48 when operating the refrigerated drawer 13.

In FIG. 4 is a section similar to the previously described figures, a fourth embodiment of the refrigerator 10 according to the invention shown, the similar is constructed, like that one out FIG. 3 , In the embodiment shown here, the lower refrigeration drawer 13 is additionally provided with an inner container 76 which has a horizontally extending upper edge of the container. In the front, the inner container 76 is about the same height or slightly lower than the upper edge 98 of the lower refrigeration drawer 13. Rear of the inner container 76 is significantly higher than the back, lower upper edge 98 of the lower refrigeration drawer 13. By this inner container 76 ensures that even in Rear part of the refrigerated drawer 13 stored refrigerated goods can not fall beyond the lower side lying above the upper edge 98 of the refrigerated drawer 13. The volume of the drawer is fully usable in this way without danger.

In the FIG. 5 Analogously illustrated fifth embodiment of the refrigeration device 10 is also constructed similar to that of FIG. 3 , The construction of the base 12 and the lower refrigeration drawer 13 and the height of the support of the lower refrigeration drawer 13 by means of the extracts (not explicitly shown here) in the support structure 22 are selected so that the lower refrigerant drawer 13 protrudes with a part 25 in the base space 14 ,

For this purpose, the front base panel 16 is formed so that its upper edge 18 is at a lower level than the base height Hs. As usual, the base panel 16 is set back relative to the front panel 20 and defines together with this a base recess 30 with a depth T1.

The cold drawer 13 has in its front lower portion 21 a recess 32 with a recess bottom 34 and a Rücksprungstirnwand 38, which connects the recess bottom with a lower-lying bottom bottom 28 of the bottom 26/90 located in the base space 14 part 25 of the cold drawer 13. The recess 32 of the lower cold drawer 13 follows in its geometry the base recess 30. The recess 32 has a greater depth T2 than the recess 30 with depth T1. The return bottom 34 traverses the top edge 18 of the base panel 16 at a distance A when the cold drawer 24 is closed. In this embodiment, this distance A defines the height of the air opening 40 between the base edge 18 and recess bottom 34, which is not included in this example a ventilation grille 42 is provided. Like from the FIG. 5 it can be seen form the base panel 16 on the one hand and return 32 of the refrigerated drawer 13 on the other hand with closed refrigerated drawer 13, a ventilation duct 40 for the air flow. The ventilation of the base space 14 is used for ventilation and cooling housed in the base space 14 units of the refrigerator 10, which are not shown here for simplicity.

The bottom bottom side 28 of the base in the base space 26 located in the base space 14 part 25 of the lower refrigeration drawer 13 is at least as much higher than the upper edge 18 of the base panel 16 that it can be moved over a movement of the refrigerated drawer 24 over this. The part 25 of the refrigerated drawer 24 located in the base space 14 can, as shown here, for the most part be insulation of the floor 26 or, at a smaller insulation thickness, also comprise the cooling volume available to the user. The user of the refrigeration device 10 is at least the volume that is above the base portion 14 and was taken in the prior art by the isolation of the bottom 26, now made available as a usable cooling volume.

In the FIG. 6 illustrated sixth embodiment corresponds to that of FIG. 5 , except that here the intermediate bottom 44 is formed as a separate component, which is the for FIG. 2 described benefits. In addition, at the recess bottom 34, a ventilation grille 42 by means of a mounting member 41 a and fasteners 41 b attached such that it is positioned with some play on the upper edge 18 of the base panel 16. The mounting member 41 a may be formed for accurate positioning, for example, as an angle plate with slots and the fasteners 41 b accordingly as clamping screws. For accurate positioning, the ventilation grille 42 also has a stop 43b formed by the grid 42 and a lower grid flange 43a projecting downwardly from the grid. For the exact positioning of the ventilation grille 42, the stop 43a is brought into abutment on the one hand with the upper edge 18 of the base panel 16 and the lower mesh flange 43b with its front side during assembly. The mounting member 41 a is then fixed by means of the fastening elements 41 b on the ventilation grille 42 and fixed to the lower refrigerant drawer 13. Any gaps that may occur between the ventilation grille 42 and the base panel are cleanly covered by the lower grid flange 43a.

It is understood that also the embodiments as they are in the FIGS. 1 to 4 are each shown to be provided with a lower refrigerant drawer 13, which projects with a part 25 in the base region 14. In addition, these drawers can be provided with ventilation grill 42. The ventilation grille 42 described above may be provided as a separate component or formed on the lower refrigerant drawer 13. The ventilation grille 42 may also have a lower grid flange and / or stop. Also, for all embodiments, the intermediate bottom 44 may be an integral part of the support structure 22 or a separate component. The intermediate bottom 44 can be fixed as a separate component either at different heights in the support structure or assigned to a specific height. Although the described embodiments are shown without bottom in the support structure 22, such may be present without departing from the inventive concept. Although the upper refrigerated drawer 11 each with an uninsulated shell and the lower cold drawer 13 with insulated drawer walls, and the false floor are shown thick insulated and described, as well as the compartment walls of the refrigeration drawer, then other embodiments may be useful under other circumstances with respect to the insulation so that individual elements or walls are designed uninsulated. This does not change the inventive idea. Also, the support structure 22 may be an independent element. The support structure may for example also be formed by side walls of other installation elements of a fitted kitchen, which are placed adjacent to the refrigeration device 10. The possibilities of variation to design the refrigerator according to the invention are large and can not all be explicitly illustrated and described here. However, the person skilled in the art knows in which way the elements of the refrigeration device according to the invention described here can usefully be combined.

The foregoing description of the embodiments according to the present invention is therefore for illustrative purposes only, and not for the purpose of limiting the invention. Various changes and modifications are possible within the scope of the invention without departing from the scope of the invention or its equivalents.
