Description

The invention relates to cooling or cooling methods for cooling or cooling goods in a half-high cooling shelf by means of a circulating air cooling stream. The invention also relates to a goods space cover with an inner side facing or facing a goods space and an outer side opposite the inner side and a half-high cooling shelf comprising a goods space, which is bounded at the bottom by a goods space floor, and a circulating air cooling flow guided through the goods space and an arrangement thereof.

Half-high refrigerated shelves are well known per se and can be found in many supermarkets or other shops in which goods to be cooled or kept cool are offered. Half-high refrigerated shelves are usually characterized in that at least one shelf and no more than four shelves are arranged or can be arranged above a goods floor in the half-high refrigerated shelf. As a rule, in the case of half-high refrigerated shelves, the floor of the goods area is also arranged at least 0.4 m, preferably 0.5 m, high above the floor in order to provide an easy-to-clean tub underneath. Half-high refrigerated shelves are usually between 1.10 m and 1.90 m high.

It is an object of the present invention to increase the flexibility with regard to the goods that can be presented or offered in a half-high refrigerated shelf in a structurally simple manner.

The object of the invention is achieved by goods room covers, half-high refrigerated shelves and arrangements as well as cooling or cooling methods with the features of the independent claims. Further, possibly also independent, advantageous configurations can be found in the subclaims and the following description.

In order to increase the flexibility with regard to the goods that can be presented or offered in a half-high cooling shelf in a structurally simple manner, a cooling or cooling-holding method for cooling or keeping goods cool in a half-high cooling shelf by means of a circulating air cooling flow can be characterized in that the circulating air cooling flow in one outside stream running outside an openable goods area cover and one inside the internal flow running through the goods area cover is divided and the external flow and the internal flow are reunited after the goods area cover has been passed through.

The goods area cover itself is cooled by the external current flowing on the outside of the goods area cover. This makes it possible to arrange goods under the goods area cover, which have to be stored, presented or offered colder than the actual cold class of the corresponding refrigerated shelf, since these are then covered by a relatively goods area cover. In addition, the goods compartment cover also ensures protection against turbulence in the air flow, which accordingly leads to improved cooling of the parts of the goods compartment covered by the goods compartment cover. The removable goods compartment cover can be opened to remove goods or to load goods. The internal flow, on the other hand, serves to cool the goods directly.

It is advantageous if the internal flow itself is divided into an underflow flowing below the goods and / or at least one shelf and an upstream flowing above the goods and / or the standard shelf and the underflow and the upstream after the goods or the shelf passes were reunited. This allows the goods to be cooled as effectively as possible, since the entire area around the goods, i.e. above and below the goods, is cooled uniformly, and therefore no warmer areas that adjoin the goods have excessively high temperatures that endanger the process of keeping fresh could. Because the two air streams are combined again, depending on the specific design, these can be returned together and accelerated and cooled in the process, which is particularly energy-efficient since both air streams do not have to be cooled separately.

Advantageously, the combination of upper current and lower current takes place before or when the internal current is combined with the external current. In this way, the better-cooled internal current can remain unaffected by the external current, which is expected to heat up more, and can still be used optimally for subsequent cooling processes. Such a procedure can also be implemented relatively easily in terms of construction.

Alternatively or cumulatively, however, it can be advantageous if the upper current is combined with the external current before the external current is combined with the internal current if this proves to be effective in terms of construction.

In a half-high refrigerated shelf, both alternatives can be implemented, for example, by covering two separate parts of the goods area with a goods room cover or two goods room covers and for one of the parts upper flow and lower flow before or when the internal flow is combined with the external flow and for the other part the upper current there is first combined with the external current and then this external current with the local current there. It is also conceivable that, depending on the specific implementation, the upper flow, for example, is divided again and one of these parts is combined with the lower flow and the other of these partial flows with the outside flow, before the inside flow and outside flow are completely combined with one another.

A combination of external current and internal current can in particular already take place in the goods room. A combination is preferably carried out at or in an air inlet of the half-high cooling shelf, at which the circulating air cooling flow is sucked in from the goods room or from the environment by means of a fan or other air-moving device and circulated past a cold point and fed to an air outlet. However, depending on the structural conditions, it can also be advantageous to provide a separate air inlet for one or some of the respective partial flows in order to then combine them elsewhere within the cooling shelf.

In order to further improve the direct cooling of the goods and on the other hand to delimit or isolate the temperatures above and below the standard shelf or a use of the goods room, it can be favorable that the underflow and / or the upstream flow through a shelf or the use of the goods room be directed. In this way, for example, goods can also be cooled from below, through the shelf or in the goods compartment. In particular, however, cold air can possibly also be conducted from above a shelf to goods which are arranged underneath, such as on a shelf located below, on a warehouse floor or on a warehouse insert.

Accordingly, an arrangement comprising a half-high refrigerated shelf and a goods compartment cover, in which the goods compartment cover is supported with your upper refrigerated shelf support on an upper cover support of the half-high refrigerated shelf, can increase the flexibility with regard to the goods that can be presented or offered in the half-high refrigerated shelf in a structurally simple manner. if the top cover support of the half-high refrigerated shelf on one shelf, on one on the store floor fitted or attachable goods compartment insert or below an air outlet or in front of or in an air outlet of the half-high cooling shelf is provided.

With this arrangement, a goods room with an internal flow and an external flow can be provided, the internal flow cooling the goods below the goods area cover correspondingly more strongly than goods that are not under a goods area cover, which can be particularly advantageous if the goods have different requirements the degree of their cooling, so that different goods of different cooling classes can be presented and provided with a half-high cooling shelf.

This can be realized in particular in that the cover support is provided in front of or in an air outlet of the half-high refrigerated shelf, since the air flow flowing out of the air outlet can then be divided by this cover support itself or by the merchandise area cover supported by this cover support with its cooling shelf support. However, the latter can also be realized by supporting below an air outlet if further air outlets are provided below the air outlet, for example for a supporting air curtain. The latter further air outlets or openings in shelves can be used to provide an internal flow if the upper cover support of the half-high cooling shelf is provided on a shelf, on a goods compartment insert placed or attachable to the goods floor, in which case in particular an upper air outlet for providing the external flow can be used.

In this context it should be explained that the arrangement of the cover support but also the goods area cover in front of the air outlet means that the cover support or the goods area cover is arranged behind the air outlet, as seen in the flow direction of the air flowing through the air outlet, so that the air flowing out of the air outlet then the cover support or the goods area cover is reached.

In order to increase the flexibility with regard to the goods that can be presented or offered in a half-high refrigerated shelf in a structurally simple manner, a goods compartment cover with an inner side that can be turned toward or facing a goods and an outer side opposite the inner side can be characterized in that the goods compartment cover has an upper cooling shelf support has that on a shelf, that on a merchandise space insert placed or attachable to a merchandise floor or that is below an air outlet or in front of or in an air outlet of a half-high refrigerated shelf is supported. Due to the various support options, a corresponding goods area cover can be placed flexibly if, for example, other areas of the cooling shelf are to be cooled more than before. In addition, various possibilities are given to mount a goods area cover accordingly and to design the support as desired.

Likewise, in order to increase the flexibility with regard to the goods that can be presented or offered in a half-high refrigerated shelf in a structurally simple manner, a half-high refrigerated shelf comprising a goods room, which is bounded at the bottom by a goods room floor, and a circulating air cooling flow guided through the goods room, characterized in that the half-high refrigerated shelf has an upper cover support which is provided on a shelf, on a goods compartment insert placed or attachable to the goods floor or below an air outlet or in front of or in an air outlet of the half-high refrigerated shelf.

It is advantageous if the upper cover support is provided on or above an air curtain wall. In this way, a goods area cover, which is supported on the upper cover support, can separate an external flow from an internal flow generated by the air curtain wall, so that the external flow can be generated directly above a goods area cover and an internal flow can accordingly be provided directly below the goods area cover through the air curtain wall ,

Accordingly, it is advantageous if the upper cooling shelf support can be supported on or above an air curtain wall. Thus, an internal current can be generated through the air curtain wall below the merchandise compartment cover, which is supported on the cooling shelf support, and the corresponding external flow can be generated directly above the refrigerated shelf support or the merchandise compartment cover.

In order to completely separate or isolate the outside flow from the inside flow, so that the two flows flow separately until the two flows are reunited or until they are recirculated via a return air duct, the half-high cooling shelf can have a lower cover support, which is on a shelf, which is provided on the goods floor, which is provided on the goods space insert which is placed or can be placed on the goods floor or which is provided on an air inlet or on the goods room side of an air inlet of the half-high cooling shelf. A combination of external and internal current thus takes place only after the part of the goods area covered by the corresponding goods area cover.

Accordingly, the goods compartment cover accordingly has a lower cooling shelf support, which can be supported on a shelf, that on a goods floor, on a goods space insert that can be placed or placed on the goods floor, or that can be supported on an air inlet or goods side of an air inlet of a half-high cooling shelf. In this way, the temperature distribution above and below the goods area cover can be effectively controlled, since external flows and internal flows, which are respectively outside and inside the goods area cover, only reunite after passage of the goods area cover and consequently only after the part of the goods room covered by the corresponding goods area cover, so that outside and inside flows can pass through this part of the goods area as independently of each other as possible.

In order to be able to open or remove the goods area cover in a particularly simple and reliable manner, a handle can be arranged on the outside of the goods area cover. It goes without saying that the handle can be made of different materials or in different shapes, as long as it can be fastened well to the goods compartment cover or can be formed on it and as long as it can be gripped easily and reliably.

It is advantageous if the goods compartment cover is transparent, preferably made of glass, since the transparent goods compartment cover allows the customer to view the goods even when the goods compartment cover is closed, without having to open the goods compartment cover. As a result, the product pressure in particular can be increased. In addition, a glass goods compartment cover is easy to clean and thus germs and bacteria are easier to remove, in particular they adhere very poorly to the glass surface.

Depending on the specific design, even a single piece of glass instead of insulating glass can be sufficient to cover the goods area, which enables a more transparent appearance and thus further minimizes barriers to purchase. With a suitable design, fogging of the goods area cover can also be avoided.

Advantageously, the goods compartment cover can comprise a flap and / or a sliding cover so that the goods compartment cover can be opened or removed as easily as possible, a flap or a sliding cover being more suitable depending on the area of application of the goods compartment cover, its dimensions and precise attachment.

In order to ensure the most energy-efficient cooling of the half-high refrigerated shelf, at least one shelf and no more than four shelves are advantageously arranged above the merchandise compartment floor in the half-high refrigerated shelf or these can be arranged there. The number of shelves distinguishes half-high refrigerated shelves from other refrigerated shelves in particular.

In particular, the goods floor can be arranged at least 0.4 m, preferably 0.5 m high, so that a trough can be arranged under the goods floor through which the return air flow of the circulating air cooling flow can be directed after passage of the air inlet and which usually is easy to clean. In particular, fans or similar air-driving devices and / or cold spots can also be provided in the tub in a manner known per se. Possibly. devices of this type are also provided in a riser duct to the air outlets arranged on the rear wall or rear side of the half-high cooling shelf.

The half-high refrigerated shelf is preferably between 1.10 m and 1.90 m high. With the dimensions mentioned, it can be ensured that the customer has access to all goods in the refrigerated shelf without any problems, for example, that no shelf is too high. In addition, the shelves can present the goods appropriately or different goods can be stored or presented separately from one another by means of several shelves.

So that the customer also has access to the goods in the cooling shelf, the half-high cooling shelf can be designed to be open to a customer side opposite the rear.

For an operationally secure fastening of the goods compartment cover, it can be fastened to the half-high cooling shelf via the support. In this respect, even if the attachment should be designed to be detachable, customers cannot then easily remove the merchandise compartment cover and only open it, so that it can also be closed easily and reliably.

It is advantageous if the support comprises a swivel joint and / or a sliding bar. In this way, with a suitable design, the safe use of the goods area cover can be realized in a structurally simple manner.

The swivel joint or the sliding bar are preferably fastened on the shelf, on the goods floor, on the goods insert, on the air inlet or on the goods side of the air inlet or below the air outlet or in front of or in the air outlet. The various mounting options can offer a very flexible use as well as very flexible installation and retrofitting options for any half-high cooling shelf, since supports for a merchandise space cover can be attached in a half-high cooling shelf in different ways. The fastening can then ensure the most reliable possible arrangement of the goods area cover.

The swivel joint and / or the sliding bar can also be fastened to a mount which is fastened to the shelf, on the goods floor, on the goods insert, on the air inlet or on the goods room side of the air inlet or below the air outlet or in front of or in the air outlet. Such brackets can be easily attached to suitable locations, such as price labeling strips or the like. Such brackets can also be designed for special fastening purposes, such as fastening in front of or on an air outlet.

It goes without saying that the features of the solutions described above or in the claims can also be combined, if appropriate, in order to be able to implement the advantages in a correspondingly cumulative manner.

In a first embodiment, as in Figure 1 a half-high cooling shelf 10 arranged on a base frame 12 comprises a plurality of shelves 23 arranged in a goods space 20, which are held by intermediate carriers 24. In this embodiment, all of the goods 21 presented on the shelves 23 and on the goods floor 22 are in a covered part 26 of the goods room 20, in that the covered part 26 is covered by a goods space cover 30.

The goods compartment covers 30 are each designed as a flap 34. Each of the three covered parts 26 of the goods space 20 has a goods space cover 30 or a flap 34. The flaps 34 are each fastened to a holder 67 via a swivel joint 65 and can be opened by means of handles 33, the flap 34 rotating about the swivel joint 65.

The uppermost bracket 67 is arranged on an air curtain wall 43, while the remaining brackets 67 are each attached to price labeling strips 19, which are provided on the shelves 23.

An air outlet 41, which generates an external flow 51, is arranged above the uppermost holder 67. The external flow 51 flows through the goods space 20 in the direction of an air inlet 42 and forms a cool air curtain, as a result of which the entire goods space 20 is cooled. The part 26 of the goods space 20 covered by the goods space cover 30 is sufficiently delimited from the rest of the goods space 20 by the goods space cover 30, so that no significant external flow 51 can get into the covered part 26 of the goods space 20, but the external flow 51 cools the covered part 26 only indirectly , The goods compartment cover 30 is designed to be correspondingly tight, but in particular the locations on the swivel joint 65 and on an upper cooling shelf support 61, the upper cover support 62, the lower cooling shelf support 63 and a lower cover support 64 need not be sealed further, since smaller leakage currents can occur the benefits hardly cause reductions.

The outside flow 51, which has entered the air inlet 42, then flows back via a return air duct 40 to the air outlet 41, so that circulating air cooling flow 50 is formed, the part of the circulating air cooling flow 50 flowing in the return air duct 40 accelerating by means of a fan 14 and from a cold junction 13 is cooled.

The air curtain wall 43 is arranged between the return air duct 40 and the goods room 20, in particular also the covered part 26 of the goods room 20, as a result of which a part of the circulating air cooling flow 50 can reach the covered part 26 of the goods room 20 as an internal flow 52 or supporting air curtain 55. In this way, the covered part 26 of the goods space 20 can be cooled particularly strongly or more strongly than the rest of the goods space 20 by the internal flow 52.

The internal flow 52 flows through the covered part 26 of the goods space 20 towards the air inlet 42, where the external flow 51 and the internal flow 52 combine again and are returned as a recirculating air cooling flow 50 in the return air duct 40, these being accelerated again, cooled and then divided again.

The goods compartment cover 30 each have an inner side 31, which faces the goods 21 or the goods compartment floor 22, and an outer side 32, which faces the customer side 15. This is particularly true in the Figures 4 . 6 and 7 shown and numbered in detail.

The goods compartment covers 30 additionally each have an upper cooling shelf support 61 and a lower cooling shelf support 63, the upper cooling shelf supports 61 comprising assemblies of the respective swivel joint 65. The goods compartment cover 30 is supported on the half-high cooling shelf 10 by means of the cooling shelf supports 61, 63.

Accordingly, the half-high refrigerated shelf 10 includes upper and lower cover supports 62, 64, on which the merchandise compartment covers 30 are each supported on the half-high refrigerated shelf 10. Here, the upper cover supports 62 each also include assemblies of the rotary joints 65 and the brackets 67.

The lower cooling shelf support 63 and the lower cover support 64 serve to support the goods compartment cover 30, as in the exemplary embodiment of the flap 34 mentioned above.

For easier operation for the operator and a corresponding presentation, the half-high cooling shelf 10, which stands on the floor 18 and has side walls 16 of the goods space 20, is designed to be open to a customer side 15.

In addition, there is the possibility of closing the goods space 20 via a night blind 17, so that the goods 21 can be kept as cool as possible in an energy-saving manner, while no presentation by or operation by a customer is necessary.

As already known for conventional or other half-high refrigerated shelves, the goods space 20 of the half-high refrigerated shelf 10 is delimited at the bottom by a goods space 22, on which goods 21 can also be stored if necessary.

The merchandise compartment floor 22 also covers a trough 29 of the half-high refrigerated shelf 10, so that part of the return air duct 40 is thereby formed. Such an arrangement can also be easily cleaned in known dimensions.

The internal flow 52 generated in addition to the external flow 51 also ensures that neither the inside 31 nor the outside 32 of the goods compartment cover 30 mists up, even though this is formed from single glass.

In addition, a protective plate 28 is arranged on the customer side 15, which prevents the customer from unauthorized intervention in areas not relevant to the customer. The air inlet 42 is arranged between the protective plate 28 and the goods compartment cover 30, in particular between the goods compartment cover 30, an air baffle plate 27 being provided from the air inlet 42 to the customer side 15. The air baffle 27 helps to effectively allow the outside flow 41 to flow into the air inlet 42.

In a further embodiment, as in Figure 2 shown, some of the goods 21 in the goods room 20 are arranged obliquely on a goods room insert 25 presented to the customer side, the goods 21 being arranged higher in relation to the goods room floor 22, so that an unused part of the goods room between the goods 21 and the goods room floor 22 20 is created. The goods 21 are cooled in the goods room 20 by the generated external flow 51 and through holes in the goods room insert 25 by means of the supporting air curtain 55. It goes without saying that, in a modified exemplary embodiment, the goods 21 can also be presented in a different way.

As especially in Figures 3 and 4 As can be seen, in this exemplary embodiment, a goods area cover 30 is supported on the goods area insert 25 and in this way forms a covered part 26 of the goods area 20, in which goods 21 can be presented directly on the goods area floor 22.

This goods compartment cover 30 has a flap 34, which is rotatably supported by a swivel 65 on an upper cooling shelf support 61 or an upper cover support 62 and is supported on a lower cooling shelf support 63 or a lower cover support 64. In this exemplary embodiment, the goods compartment cover is therefore not fastened to the half-high refrigerated shelf 10 or to the goods compartment insert 25, but is only supported on the latter. In the present exemplary embodiment, the swivel joint lies in an area of the merchandise compartment insert 25 shaped as a half-shell, as a result of which the merchandise compartment cover 30 rotates via the swivel joint 65 in the holder 67 and can thus be opened and closed, but the merchandise compartment cover 25 can also be completely removed in a particularly simple manner by simply lifting the goods compartment cover 25 with the swivel 65 out of the half-shell.

Because the upper cooling shelf support 61 or the upper cover support 62 is of such a simple design, the goods cover 30 can be easily removed, for example for cleaning or maintenance purposes.

It goes without saying that, depending on the specific implementation, additional goods space covers 30 may be provided for the goods 21 located above or a goods space cover 30 spanning several floors. Likewise, in modified embodiments, the swivel joint 65 can be designed such that the goods compartment cover 30 is fastened to the half-high cooling shelf 10 or to the goods compartment insert 25.

This exemplary embodiment can be modified quickly by replacing or removing the goods compartment insert 25.

The rest of the arrangement is similar to that of the previous example, with the air streams being generated and directed accordingly.

In this way, foods to be cooled to different degrees, for example because they correspond to different cooling classes, can be cooled, presented and made available to the customer in a single, half-high cooling shelf 10.

The swivel joint 65 in the first exemplary embodiment is designed as a fixed swivel joint, so that it can simultaneously be regarded as a holder 67 for the goods compartment cover 30. The training can be, for example, by a fixed bolt or similar fixed storage can be provided. In another possible embodiment, as the Figure 3 clarifies, the goods area cover 30 is connected to the swivel 65.

As it is especially in the Figure 4 is illustrated, the internal flow 52 in the covered part 26 of the goods space 20 is directed to the air inlet 42. At the same time, the outside stream 51 also flows into the air inlet 42, but the outside stream 51 and the inside stream 52 do not unite before they have entered the air inlet 42. This is made possible by the fact that the lower cooling shelf support 63 or the lower cover support 64 is arranged directly on the air inlet 42, the internal flow 52 flowing into the air inlet 42 on the inside 31 of the goods cover 30 and along the outside 32 of the goods room cover 30 External stream 51 flows into the air inlet 42.

In a further embodiment, as the Figure 5 represents, an oblique presentation of the goods 21 oriented towards the customer side 15 is also provided, but the entire goods 21 are covered by the goods area cover 30. Like that Figures 6 and 7 To show in more detail, the circulating air cooling stream 50 is divided directly into an outside stream 51 and an inside stream 52 or upper stream 53 at the air outlet 41. An internal flow 52 in the area under the goods 21 is also also provided via the air curtain wall 43 and cools the warn 21 as an underflow 54 through holes in the goods compartment insert 25.

Overall, the cooling of the goods is shaped by three currents. Among other things, from the outside flow 51 flowing past outside the goods area cover 30 in the goods room 20 and through the inner flow 52 located in the covered part 26 of the goods room 20, the inner flow 52 being divided into two different flows, the upper flow 53 and the lower flow 54. The upper flow 53 flows in the area between the goods 21 and the goods space cover 30 towards the air inlet 42. The lower flow 54 flows between the goods 21 and the goods room floor 22 towards the air inlet 42. While the upper flow 53 is formed directly at the air outlet 41, the Underflow 54 through the air curtain wall 43 in the return air duct 40. Because of the holes in the merchandise compartment insert 25, the underflow 54 and the upper stream 53 can unite on their way through the merchandise compartment 20 and, if necessary, also separate again.

Thus, a particularly strong cooling takes place within the goods area cover 30, since these are cooled both below the goods 21 and above the goods 21 between goods 21 and goods area cover 30 and in addition the external flow 51 covers the entire covered part 26 of the goods area 20 or the Warehouse cover 30 keeps cool.

In this exemplary embodiment, the external flow 51 and the internal flow 52 only unite again in the air inlet 42, first of all the upper flow 53 and the lower flow 54 before they then unite with the external flow 51. It goes without saying, however, that in different embodiments, for example in the first exemplary embodiment, the external flow 51 also initially unites with the upper flow 53 and then with the lower flow 54.

The upper cooling shelf support 61 and the upper cover support 62 are arranged directly on the air outlet 41. In this way, the circulating air cooling stream 50 at the air outlet 41 can be divided directly into the external stream 51 and the internal stream 52 or subsequently the upper stream 53.

The lower cooling shelf support 63 or the lower cover support 64 is arranged in the area of the air inlet 42 in such a way that the inner stream 52 can flow into the air inlet 42 along the inner side 31 of the goods cover 30 and at the same time the outer stream 51 along the outer side 32 of the goods room cover 30 can flow into the air inlet 42.

The goods compartment cover 30 of the third exemplary embodiment is designed as a sliding cover 35, so that a customer can get to the cooled goods 21 by moving the goods compartment cover 30.

In order to be able to open and close a sliding cover 35 accordingly, a sliding strip 66 is provided, which is provided by the supports 61, 62, 63, 64.

The upper cooling shelf support 61, the upper cover support 62, the lower cooling shelf support 63 and the lower cover support 64 are designed such that they can be installed in a particularly simple manner on any half-high cooling shelf 10. In this way, a half-high cooling shelf 10 can be easily retrofitted via the supports and the correspondingly designed sliding cover 35 in order to achieve the advantages of the half-high cooling shelf 10 described above. The supports are extremely easy to mount on the air inlet 42 and on the air outlet 41. It goes without saying that instead of a sliding cover 35, for example, a flap 34 can also be used if this configuration proves to be advantageous for the given cooling shelf 10. In addition, any other types of goods compartment cover 30, in particular different types of openings, are also possible, provided that they can be installed in such a way that the circulating air cooling flow 50 can be divided accordingly into external flow 51 and internal flow 52. In addition, it goes without saying that the goods 21 can also be presented in various ways, provided that a corresponding area for generating an undercurrent 54 is possible below the goods 21.
