    COOLING HARDWARE WITH APPROVED PRODUCT PRESENTATION SURFACE
    The invention relates to a refrigerated display with a customer-inclined product presentation area through which a cooling trough arranged thereunder is at least partially completed, and having a circulating air cooling system, which is adapted to guide an air flow of cooled air from the cooling trough on the goods display area.
    STATE OF THE ART
    A variety of cooling devices are known from the prior art, which serve the presentation of refrigerated and / or frozen goods in sales rooms. Here are basically freezers, which are available for example in the form of Inseltruhen accessible from several sides on a sales area to distinguish from refrigerated counters, which have a customer and a control page according to the function of a shop counter.
    The latter are usually used for the presentation of unpackaged food, in which a certain standard of hygiene is to ensure their function in a refrigerated display the merchandise is presented on one side in the direction of the customer, whereas the access to the goods from the operating side , It is desirable for optimum presentation that a goods display area of the refrigerated display is inclined in the direction of the customer; The more inclined a given presentation surface is, the greater is the viewing angle β under which the presented goods are perceivable by a customer.
    With increasing tendency of the goods presentation area, however, there is the problem that the cooled air flows from the goods presentation area, the slope of which, swiftly to the customer's viewing side. Only by a correspondingly strong and steady supply of a cooling flow, the cooling of the uppermost arranged goods can be guaranteed. Furthermore, the cold flow flooded the goods presentation area before it is usually performed on the deeper side back into a lying below the goods presentation area cooling trough.
    In this case, a strong flow of cold leads with a scattering associated with it to a correspondingly strong and large-scale cooling of a customary visor, or windscreen of the refrigerated display. The cooling of the windscreen on its outer side causes the condensation of moisture contained in the room air of the sales room, wherein the precipitating condensation in turn leads to an impairment of the visibility of the presented goods. This effect increases as the temperature difference between the counter interior and the sales room increases.
    For goods that must be presented below the frost limit, such as ice cream, for this reason, the goods presentation areas known refrigerated counters usually only a slight inclination. Alternatively, in refrigerated counters with a more inclined, i. 15 ° inclined presentation surface, the windscreen in the form of a strong insulating glazing executed. Such an embodiment is described for example in DE 2961 3952 U1. In addition to the higher costs compared to simple glazing, however, insulating glazings often have the property of leading to a visual distortion of the presented goods.
    DISCLOSURE OF THE INVENTION
    The object of the invention is to provide a refrigerated counter, which allows a good, visually unadulterated presentability of the goods offered under a large viewing angle.
    The object is achieved by the features of the independent claims. Advantageous embodiments of the invention are specified in the subclaims.
    Provided according to the invention is a refrigerated display with a customer inclined to the product display area through which a cooling trough arranged underneath is at least partially completed. with a recirculation air cooling system configured to direct an airflow of cooled air from the cooling pan to a higher region of the inclined merchandise display surface and from a lower region of the merchandise display surface back to the cooling pan, wherein the merchandise display surface is at least partially interrupted by at least one return air channel , and wherein the circulating-air circulation cooling system is set up to produce on the goods display surface two air streams, which are oriented at least partially opposite each other and oriented respectively in the direction of the return air channel.
    In this case, the concept of inclined goods presentation surface includes those embodiments of a goods display area, in which the effect of an inclined goods display surface is effected by a staircase or cascade-like alignment of faces. Also included in the concept of inclined goods presentation area is an arrangement of vessels or holders, which means that the goods are presented in different, in particular the customer side sloping heights.
    In other words, according to the invention is thus provided that on the inclined goods display surface two opposing air flows are generated, of which a first, upper air flow from top to bottom, and a second, lower air flow is directed from bottom to top, and that both Air streams where they meet, are led into a common return air duct through the goods presentation area back into the cooling trough. In this case, the return air duct is preferably arranged centrally within the goods presentation area.
    Such a refrigerated counter has several advantages. A first advantage is that, due to the return air channel located within the goods presentation area, the free distance of the air flow to be traversed outside of channels is shortened over the presented goods. This ensures, on the one hand, a more constant cooling temperature, since the air stream warms up, releasing its coldness with increasing distance. On the other hand, but also a lower flow velocity and a lower scattering are achieved, since the overflowed from the air flow Gefallstrecke is shortened. In other words, by inclining a return air passage into the goods display surface, the inclination of the goods display surface can be increased without increasing the flow velocity and the scattering of the air flow. In this case, the generation of opposing air flows has an advantageous effect. By generating a lower air flow directed counter to the upper air flow, the upper air flow is slowed down so that its return via the return air duct into the cooling trough is facilitated. If the lower air flow is scattered in the same way as the upper air flow when it sweeps over the goods display surface, the upper air flow is quasi braked in its entirety and can be returned to the cooling trough through the return air duct. Thus, a caused by the upper air flow cooling of a windshield is significantly reduced to excluded.
    Advantageously, the refrigerated display on baffles or nozzles for the alignment of air currents. In this case, it has, in particular advantageous baffles, which are suitable to let the lower air flow at a shallow angle up on the goods presentation area. Such baffles offer several advantages. On the one hand, they allow the lower air flow to be dimensioned in terms of mass and velocity in such a way that, after it has flown up the inclined presentation surface against gravity, it still has enough kinetic energy to decelerate the upper air flow. On the other hand, they are also suitable for keeping the lower air flow away from a windshield.
    Advantageously, the refrigerated display also on baffles, which are suitable to the upper
    Align the air flow at a shallow angle downwards, so that the dispersion of the air flow can be limited.
    Further advantageous are the upper, downward and the lower, upward air flow generated by a common fan. In this case, the strength of the upper and lower air flows is also controllable in relation to one another in order to be able to compensate, for example, the accelerating or braking effect of gravity or different flow resistances. For this purpose, the refrigerated display, for example, have a baffle for controlling / distributing the air streams. Alternatively or additionally, a change in the relation can also be achieved by changing a flow resistance to be overcome for at least one of the air streams. In a further embodiment, the strength of the air flows can be adjusted individually. In this case, the cooling counter for the generation of air streams, for example, each separate fans.
    Advantageously, the refrigerated display on an at least predominantly closed essay with a windscreen, wherein at least the front window is made transparent.
    Such an essay, for example in the form of a glass dome opened only to the operating side, in addition to the hygienic aspects has the advantage that even in a drafty ambient situation, the intended movements of the cooled air streams are not substantially affected.
    In this case, an at least predominantly closed article means that the essay, for example, a rectangular design, is at least predominantly closed by three sides, wherein a predominantly closed side is to be understood as an embodiment having only smaller openings in relation to the side surface , which are also in surrounding drafts unsuitable to affect a movement of the cooled air streams within the refrigerated display. In addition, the article may have a closed upper side and / or a closable operating side.
    Furthermore, the attachment is advantageously designed such that it supports the formation of an air vortex above the lower air flow, the air vortex, driven by the lower air flow, air moves along the windshield from top to bottom. For this purpose, the attachment advantageously has at least one height, which corresponds approximately to the distance which the lower air flow covers over the goods presentation surface. Furthermore, baffles can support the formation of such a vortex, in a further embodiment, such sheets, which have an effect in the context of counter lighting, serving there for example for shielding or reflection, are arranged such that they additionally support the formation of the vortex.
    Advantageously, the flow velocity and / or the exit angle of the lower air flow are adjustable, wherein they are advantageously set such that the vortex described above forms the described vortex causes relatively warm air from the upper region of the essay, the windscreen flows down and counteracts their cooling by the cold air flow.
    Further advantageously, the front screen of the article on a vertical orientation. In order to reduce the risk of fogging of the windshield, the angle δ is chosen to be as large as possible in relation to the goods display surface or their angle to the orientation of the lower cold air flow. In other words, this requirement means that the windshield is tilted as much as possible in the direction of the customer side in relation to the goods display area. However, this is counteracted by an increasing reflection effect, due to the fact that an angle ε between the orientation of the front pane and a viewing direction of a customer decreases with increasing angle δ, so that an increasing reflection effect of the pane impairs the presentation of the goods. In the interaction of both effects, a vertical orientation of the windshield is approximately an optimum, the vertical orientation offers further advantages in terms of manufacturing and design.
    In an advantageous embodiment of the refrigerated display case, the front glass of the attachment made of float glass or toughened safety glass (tempered safety glass) is executed. In comparison to coated or multi-pane insulating glass, this offers a less visually impaired view and thus a substantially unadulterated view of the presented goods.
    Advantageously, the refrigerated display also has a baffle plate, which is arranged parallel to the front window of the essay. Such a baffle plate protects the windshield from the impact of the cold air flow and thus reduces the risk of their fogging. The baffle plate is advantageously carried out only up to a height which corresponds approximately to the height of the upper edge of the merchandise display area on the operating side, so that a customer's view of the merchandise display area essentially does not have to be done by the baffle plate. In this arrangement, in a conventional viewing perspective of a customer, the proportion of the merchandise display area that is visible only through the baffle plate is relatively low.
    In an advantageous embodiment of the refrigerated display case, the return air duct is formed as a gap or in the form of a plurality of adjacent channels. Such a configuration is particularly advantageous in relation to the depth of construction wide refrigerated counters, as they are frequently encountered shop fitting advantage. In this case, it is advantageous to orient a return air duct designed as a gap or a plurality of adjacent channels parallel to the upper and / or lower edge of the goods presentation surface.
    DRAWINGS
    The invention will be explained in more detail with reference to the accompanying drawings with reference to preferred embodiments.
    [0026] FIG. 1 shows a first exemplary embodiment of a refrigerated display unit according to the invention in cross section; Fig. 2 shows the path of the air flows in the first embodiment of Fig. 1; Fig. 3 is a longitudinal section of the embodiment of Figure 1 with a presen- tation of the return air duct. Fig. 4 a) - i) embodiments of an inclined goods display area.
    Fig. 1 shows a first preferred embodiment of a refrigerated display case 1 according to the invention with an inclined to the customer side merchandise display surface 2. By the merchandise display surface 2 is arranged below a cooling pan 3 at least partially completed. The refrigerated display case 1 has a circulating air circulation cooling system which is set up to guide an airflow 7 of cooled air out of the cooling pan 3 onto a higher area 4 of the inclined goods display area 2 and from a lower area 5 of the goods display area 2 back into the cooling pan 3. The goods presentation area 2 is interrupted by a return air channel 6. Furthermore, the circulating-air circulation cooling system is set up to produce two air streams 7, 8 oriented at least partially opposite one another, in each case in the direction of the return air channel 5, on the goods display surface 2. The return air duct 6 is arranged centrally between an upper edge 10 and a lower edge 11 of the inclined goods presentation surface 2. Furthermore, the refrigerated display 1 deflecting plates 9 for aligning an air flow 7.8. In this case, the baffles 9 are suitable for a lower air stream 8 at a shallow angle upwards, and to let an upper air stream 8 at a shallow angle down on the goods presentation area 2.
    Due to an inclination of the goods display surface 2 of about 15 ° increases the viewing angle ß, under which a customer can perceive the goods display area 2. An angle ε denotes the angle with respect to a windshield 14, below which the customer sees the lower edge of 11 of the goods display surface 2. The windscreen 14 is perpendicular and directed at an angle δ to the goods display area 2 from.
    2 shows the path of the air streams 7, 8 in the embodiment of FIG. 1. In addition to the features explained in FIG. 1, it can be seen from FIG. 2 that an upper, downwardly directed air flow 7 and a lower, upwardly directed air flow 8 can be generated by a common fan 12. After passing through at least one fan 12, the air streams 7 and 8 for cooling flow through an evaporator 19 in order to then be passed through baffles 9 on the goods presentation area 2. From there, the air streams 7, 8 flow through the goods presentation area 2, releasing the cold or absorbing heat along the goods to be cooled in opposite directions to the common return air duct 6 to be sucked there by at least one fan 12.
    The refrigerated display case 1 has a three-sided and top-closed attachment 13 with the front panel 14, wherein the sides and the front are all made of single-pane safety glass. The attachment 13 has a height above the goods display surface 2 which is greater than the distance which the lower air flow 8 travels above the goods presentation surface 2. Thus, the article 13 allows the formation of an air vortex 15 above the lower air stream 8, which is driven by the lower air stream 8 along the windshield 14 moves air from top to bottom. Symmetrically, another counter-rotating air vortex 16 can be seen. Furthermore, the front screen 14 has a vertical orientation. To the windshield 14 parallel and closely spaced to her a baffle plate 17 is disposed in its lower region. The baffle plate 17 is made up to a height which corresponds approximately to the height of the upper edge 10 of the goods display surface 2 on the operating side.
    Fig. 3 shows a longitudinal section of the embodiment of FIG. 1 with a representation of the return air duct 6. Here, the return air duct 6 is designed as a gap 18, which extends over the inner width of the cooling pan 3 and parallel to the upper edge 10 and lower edge 11 of the apparent from Fig. 1 goods display area 2 is oriented. Below the gap 18, a plurality of fans 12 for generating the air streams 8, 9 are arranged.
    4 shows several embodiments of an inclined goods display surface 2. This can, for example, in the form of a planar surface according to 4a, in the form of a staircase with flat sections as shown in FIG. 4b, with inclined sections as shown in FIG. 4c, or even without planar sections as shown in FIG. 4d be executed. In addition, an arrangement of containers or holders, which leads' that the goods are presented in different, in particular the customer side sloping heights, cause an inclined goods display surface 2. 4e shows containers 20 of the same height, which are arranged on an inclined plane and thereby form an inclined goods display surface 2 with respect to goods presented therein. Likewise, a stepped arrangement of such containers 20 according to FIG. 4f or according to FIG. 4g leads to this effect. Furthermore, holders for individual objects according to FIGS. 4h and 4i, such as, for example, popsicles, which cause the individual objects to be presented at different heights, are also considered inclined product presentation area 2.
