Description

Contai nerkühlregal

[01] The invention relates to a container cooling rack.

[02] Such container refrigerated shelves are technologically very similar in technology to conventional refrigerated shelves, which are equally intended in particular for commercial use in the food industry, such as for sale of meat, vegetables, fruit or dairy products. Such refrigerated shelves, as well as container refrigerated shelves, comprise a goods space that is open to at least one user side for access to goods. Depending on the specific embodiment, refrigerated shelves can have glass doors or the like here, which, however, is naturally not provided for in container refrigerated shelves. Other refrigerated shelves are in themselves open during the opening hours of corresponding stores that hold such refrigerated shelves, so that customers can directly and directly take out goods. For energy-related reasons, it may be provided that energy losses are minimized by covers, such as roller blinds and the like, outside of business hours.

The conventional refrigerated shelves comprise a framework surrounding the goods space with a ceiling element and a wall, wherein in the ceiling element along the open or apparent user side a cold air supply for the goods space or in conventional refrigerated shelves is provided for a cold air curtain. The cold air supply is provided with a cold air supply comprising a arranged at least partially in the conversion and in the ceiling element main air duct with an air intake and arranged in the main air duct fan and arranged in the main air duct cold point of a cooling unit.

Notwithstanding conventional refrigerated shelves container refrigerated shelves have at least one receptacle for a goods-carrying container, such as for a trolley or for goods pallets, which can be equipped with containers on the user side. This requires that a bottom group of the container cooling rack for trolley or goods pallets carrying pallet truck must be accessible, so that a corresponding assembly can be done. Such a configuration has the advantage over conventional refrigerated shelves that egg loading or re-sorting of the container cooling shelves in the field of recording can be done quickly and efficiently even with large quantities of goods. Accordingly

CONFIRMATION COPY Container refrigerated shelves do not have floor trays, such as those found in conventional refrigerated shelves.

[05] It is understood that in the upper areas of the container cooling shelves and conventional shelves, as they are known in conventional refrigerated shelves, may be provided. In such cases, then only the space remaining under the lower shelf is available as a receptacle for the containers.

[06] It is an object of the present invention to increase the energy efficiency of container refrigerated shelves.

[07] As a solution container refrigerated shelves are proposed with the features of claims 1 and 6. Further advantageous embodiments can be found in the subclaims and the following description.

[08] The invention is based on the basic knowledge that in order to increase the energy efficiency of container refrigerated shelves, a suitable air curtain that forms on the user side of the goods, is advantageous, in particular for this purpose, a corresponding intake, which, if possible, the cold Air of the cold air curtain with as little warm room air sucks in this regard is an advantage.

Accordingly, it is advantageous if a bottom plate with a support for the container and with the air intake, is provided in the bottom region of the container cooling shelf, wherein the air intake extends parallel to the cold air supply. In this way, an air intake substantially on the user side, ie before the goods are made, so that all goods that are located within the goods space, including in the containers, are separated over the cold air curtain to the outside. This also avoids, in particular, that warmer room air mixes with the cold air of the cold air curtain to an inadmissible extent.

[0010] Cumulatively or as an alternative to this, a front closure with the air intake, which can be revealed for fitting to the container, can be provided. By such a front end, which has an active air intake, the air intake is not directly on the ground but by the front end itself spatially increased, which in turn means that less room air is sucked. In addition, this embodiment allows, when the front end sufficiently tight against the remaining wall of the container cooling rack, the design of an arrangement that the floor trays at similar to conventional refrigerated shelves, and has already proven in terms of their energy efficiency in conventional refrigerated shelves. The Öffenbarkeit for placement purposes, however, obstructs the loading of containers, so for example with trolleys or pallets only insignificantly.

[1 1] In a preferred concrete implementation of the front end may include a front end air duct, on the one hand has the air intake and on the other hand via a duct outlet with an air intake of a bottom plate and / or with another channel entrance of the main air duct is connectable. In this way, the sucked on the air intake cold air of the cold air curtain can be easily and structurally reliable out of the Frontabschl uss in the main air duct. It is understood that, where appropriate, other solutions, such as a connection via air hoses or the like may come to applications, the above solutions have the advantage that they can be realized with little structural effort across the width of the entire container cooling rack away, so that even very large channel cross sections can be implemented without further ado.

[12] Preferably, the front closure is accessible, so that customers - but possibly also operating personnel - can ascend to the front end to reach shelves or in areas that are located higher in the container cooling rack.

It is also conceivable to design the front end with rollers or sliding so that it can be released from the bottom plate or from the other stand of the container cooling rack and pushed to the side to equip the receptacle with containers.

It is also conceivable to store the front end with rotatably mounted lifting arms on the framework of the container cooling rack, so that the front end can be folded upwards, so as to clear the way for the container. A corresponding folding up or down can be supported by mechanical aids, such as gas springs. Likewise, it is conceivable to form the front end over lateral rails, which are provided on the framework of the container cooling rack, displaceable upwards, wherein this movement can also be supported by suitable mechanical aids, such as counterweights.

In a concrete implementation, the bottom plate of the container cooling rack, in which the air intake is provided, be designed to be interrupted, so that wheels of trucks or rolling stock on the floor remaining introduced into the recording can be. This avoids that the corresponding wheels must be moved up to get to the bottom plate, so that a loading of the receptacle for operators over conventional container refrigerated shelves is not difficult.

[16] If it should be found in such a configuration that the forming cold air curtain does not fall down sufficiently uniformly, since due to corresponding recesses of the bottom plate naturally no air suction can take place there, it is advantageous if the bottom plate is formed continuously. Alternatively, a header in front of the bottom plate may be provided with a continuous or with a widened air intake similar to the front end, which can be removed from the assembled and reassembled after loading. In practice, however, a continuous floor slab has proven to be relatively efficient and reliable.

Preferably, the cold air supply and the air intake each have a length in the horizontal direction and parallel to the user side, wherein the length of the air intake deviates by a maximum of 50% of the length of the cold air supply. It has been found that larger deviations cause large energy losses. Preferably, the length of the air intake differs by a maximum of 20%, in particular by a maximum of 10%, of the length of the cold air supply, so that the cold air curtain can be formed as parallel and uniform as possible.

Overall, it is advantageous if the length of the cold air supply or the air intake is at least 90%, preferably 95%, of the open user side, so that the corresponding cold air curtain covers the user side as wide as possible.

[19] Preferably, the bottom plate is also provided with an air duct, so a bottom plate air duct, so that the air from the air intake can be directed in a structurally simple manner to the main air duct. It is understood that both the bottom plate air duct and the front end air duct can be made substantially airtight. Optionally, it is also conceivable to design an air channel open on the bottom side, as long as corresponding edge elements ensure reliable operation of the air and in particular limit the penetration of warm air to a minimum. [21] It is likewise advantageous if the respective connections between the different air ducts are accordingly airtight or approximately airtight. In particular, when the bottom plate is formed continuously and has a very wide air duct, this can be stiffened against a possible bending or supported by support elements.

[23] Furthermore, it is understood that the respective air intake can be covered by a grid in order to minimize the risk of objects penetrating into the air duct. Likewise, known from the field of conventional refrigerated shelves gutters or other cleaning devices may be provided accordingly.

To form a sufficient channel cross section for the bottom plate air duct, the bottom plate may well be 1 cm or a little more high. In order to push the container up on the bottom plate, it is advantageous if the bottom plate includes a ramp or to the same a ramp can be attached. In this way, a loading of the receptacle is facilitated with containers.

The ramp can, depending on the concrete implementation of the present invention, be foldable or raised or pushed, so that it, if it is not used for a placement, support the formation of a floor pan in the recording or attaching a Front end not hindered.

Alternatively, the ramp may have openings that serve as an air intake, or have the air intake itself. Then, a movable or hinged version of the ramp is not necessary, so that the ramp itself has the air intake. It is also conceivable that a front end with its channel outlet attaches the front end air duct to the openings of the ramp, so that the air sucked through the front end and its air intake via this channel exit and the openings of the ramp, which then serves as a channel entrance of the main air duct, to the main air duct arrives.

[28] It is understood that the features of the solutions described above or in the claims can optionally also be combined in order to be able to implement the advantages in a cumulative manner.

[29] Further advantages, objects and characteristics of the present invention will be explained with reference to the following description of exemplary embodiments, which are also illustrated in particular in the appended drawing. In the drawing show:

Figure 6 shows a third embodiment of a container cooling rack in a similar view as Figures 1 to 5;

FIG. 7 shows a fourth exemplary embodiment of a container cooling rack in a similar representation as FIGS. 3 and 4 with the front end removed;

Figure 8 shows the arrangement of Figure 7 with attached front end in a similar representation as Figures 3, 4 and 7; and

Figure 9 is a detail view of a floor slab with ramp, as it can be used in the embodiments of Figures 6 to 8.

The container cooling racks 1 shown in the figures each have a goods compartment 3 for food or similar perishable goods, which is open to a user side 2. Not shown is a possible night cover, which - depending on the concrete implementation of existing embodiments - if necessary, for example, can be pulled down as a roller blind on the user side.

The container refrigerated shelves 1 have a receptacle 4 in the goods space 3 for receiving containers 5, such as trolleys or goods pallets, so that the container cooler shelves 1 quickly with appropriate goods, even if it is large quantities or heavy goods , can be equipped.

The container cooling shelves comprise a stud 6, which carries a ceiling element 7 in a ceiling region 16 and a wall 8, which closes the container cooling shelf 1 apart from the user side 2 laterally and is constructed correspondingly insulating.

In the wall 8 of the container cooling shelves 8, a main air duct 1 1 is guided in each case, which also extends into the ceiling element 7 and in which a fan 13 and a cold point 14, as a rule, an evaporator of a cooler unit, are arranged.

As a result, a cold air supply 10 to a cold air supply 9 for the goods space 3 and for a cold air curtain 28 before the goods space 3 gewährleitstet. It is understood that the container cooling racks 1 each have a longitudinal extent perpendicular to the plane of the drawing and can be quite long over several meters, to over 10 meters or even longer. Optionally, in order to ensure appropriate cooling performance, several main air channels 1 1 or more cold spots 14 and fans 13 are provided. Likewise, in particular for reasons of stability, vertical partitions or additional support means of the stud work 6 can serve for stabilization. As a rule, the container cooling racks 1 are delivered in longitudinal sections between 1 meter and 3 meters and possibly assembled on site, so as not to complicate a removal and transport unnecessary.

All the container cooling racks 1 illustrated in the figures have an air intake 12 for the main air duct 11 in the bottom area 15, which is connected to the main air duct 11 via a floor plate air duct 25 in a base plate 17. As already stated above, a correspondingly close airtight connection between the channels 25 and 1 1 is advantageous. In modified embodiments, the bottom plate can be designed to be open at the bottom so that a corresponding air duct is formed on the one hand by the bottom plate and on the other hand by the bottom on which the container cooling shelf 1 stands. In such an embodiment, it is advantageous if the air duct formed thereby is bounded laterally by corresponding boundaries on the bottom plate.

Depending on the specific embodiment of the bottom plate 17, the bottom plate 17 here not shown supports within the bottom plate air channel 25, which prevent or minimize bending of the bottom plate 17 in the bottom plate air channel 25. If appropriate, further reinforcements of the bottom plate 17 can alternatively or cumulatively be provided for this purpose.

[38] In the embodiments shown here, the bottom plate 17 is formed continuously in the longitudinal direction and forms a support 18 for the container 5. In modified embodiments, the bottom plate or the bottom plate air duct may be interrupted, so that wheels not on the bottom plate air duct but next to the same for standing come and the container 5 does not have to be raised by the height of the bottom plate 17 including the bottom plate air duct 25 during loading.

[39] In the container cooling rack 1 shown in FIG. 1, a hinged ramp 19 is provided, which facilitates the sliding of the containers 5. For loading, this ramp 19 covers the air intake 12, which, however, is energy-critical, since such Loading operations last only a short time of the total operating time of the container cooling rack 1. After loading, the ramp 19, which is attached to the bottom plate 17 via a hinge, folded up, so that the air intake 12 is released. In addition, the ramp 12 forms together with the remaining wall 8 of the container cooling rack 1 in the folded state in the bottom region 15 a trough, which holds cold air back. The released air intake 12 can then extend parallel to the cold air supply 9 and in this embodiment over the same length of the cold air supply 9 readily.

[40] In an embodiment modified from the exemplary embodiment according to FIG. 1, the ramp 19 can also be made detachable or slidable on or into the base plate 17.

[41] Also, the embodiment illustrated in Figures 2 to 5 (wherein in Figures 2 and 5, for clarity, the fan 13 is not shown again) has a ramp 19, which is formed correspondingly hinged. This ramp may possibly be removable or designed to be pushed in any way. [42] In the exemplary embodiment illustrated in FIGS. 2 to 5, after any loading operations have been completed and the ramp 19 has been folded up, a front closure 20 is pushed in front of the base plate 17, which has in its body a front-end channel 21 which, on the one hand, has an air intake 12 of the front end 20 and on the other hand with a channel outlet 22 is connected. Here, the air intake 12 of the front end 20 is directed upward and compared to the air intake 12 of the embodiment of Figure 1 arranged elevated and the channel output 22 when the front end 20 is pushed in front of the bottom plate 17, connected to a channel inlet 23 of the bottom plate air duct 25, wherein the channel inlet 23 substantially corresponds to the air intake 12 according to the embodiment of Figure 1. The higher and upwardly arranged air intake 12, on the one hand, promotes the formation of a possibly parallel cold air curtain 28. In addition, the risk that foreign air, which is naturally slightly warmer, is sucked minimized.

[43] For safety reasons, in the embodiment illustrated in FIGS. 2 to 5, the front end 20 is locked to the floor panel 17 or otherwise to the stud 6, so that the front end 20 can also be entered by customers or personnel to reach higher regions, such as goods on any shelves 24, reach. [44] In the embodiments illustrated in FIGS. 6 to 8, a separate and movable ramp 19 has been dispensed with. Rather, the ramp 19 is integrated into the bottom plate 17 i, as exemplarily illustrated in detail in FIG. 9, and the air intake 12 is realized through openings 26 in the ramp 19.

By such a configuration can be dispensed with a hinged ramp 19, as provided in the container cooling rack 1 according to figures 1 to 5, so that even hereby a ramp 19 including an air intake 12 structurally ei nfach can be realized.

It is also possible to combine a bottom plate 17, which corresponds to the arrangement of Figure 9, with a front end, if this example has a ramp 19 corresponding approach that corresponds directly to the ramp 19, as this in the embodiments is realized according to Figures 6 to 8.

[47] Thus, the exemplary embodiment according to FIG. 6 has a front end 20, which is arranged on a lever arm 27, so that the front end 20 can be folded up on the lever arm 27. The lever arm 27 is attached via a not quantified rotary joint to the stator 6. Optionally, it is also conceivable the front end 20, which comes in the embodiments of Figures 2 to 5 are used to attach via such a lever arm to the container cooling rack. Depending on the specific implementation, further detents may be provided. It is also conceivable, instead of a lever arm vertically directed guide rails or the like to use for a guide of the front end 20.

[48] In the embodiment illustrated in FIGS. 7 and 8, the front end 20 is designed to be removable and displaceable according to the exemplary embodiment according to FIGS. 2 to 5, whereby this front end is likewise designed to be complementary to the ramp 19 as shown in FIG , so that can be dispensed with a hinged or otherwise movable ramp 19.

Through the bottom plate 17, the ramp 19 and the frontal end 20 respectively air intake 12 are provided, which extend over long lengths substantially parallel to the cold air supply 9. The air sucked in this way passes through the bottom plate air duct 25 in the main air duct 1 1, where it is sucked by the fan 13 and transported upwards. In this case, the air passes through a cold point 14 of a refrigeration unit, such as an evaporator. About the formed in the wall 8 and in the stator 6 main air duct 1 1, which, as in conventional refrigerated shelves well known, may also have other openings to the goods compartment 3, the cold air enters the ceiling element 7 and is on the cold air supply 10 of the cold air supply 9 for a cold air curtain 28 (shown by way of example in Figure 2) supplied.

[51] This cold air curtain 28 isolates the goods compartment 3, in particular against room air, whereby it inevitably heats up a bit. By the air suckers 12, which extend over a large length parallel to the cold air supply 9, a large part of the cold air curtain 28 is sucked in, so that the cooling at the cold spot 14 and the performance of the fan 13 can be minimized. This applies in particular when using the front end 20 with its higher air intake 12.
