Definitions

• the invention relates to the field of refrigerated sales cabinets (abbreviated MFV), intended to display and preserve products at a reduced temperature which prolongs their good state of conservation; for the presentation and sale of many food products, this temperature is imposed by the regulations.

More specifically, it concerns a so-called “open vertical” refrigerated display case, that is to say having a substantially vertical face which remains open so that the products displayed for sale can be apprehended.
• the thermal confinement of the space where the products displayed for sale are located is achieved by a curtain of cold air extending from the top of the open face to the bottom of said open face.
• air blowing means and air suction means are provided, which are placed substantially plumb with one another.
• the window is hollow, so as to form an air vein, that is to say an air circulation duct which allows the latter to be returned from the suction means in the direction of the blowing means. .
• the invention relates to a new showcase of this type which presents a means of humidification by nebulization.
• the state of the art includes in particular different types of refrigerated display cases which are on the market, and which are the subject of standard NF EN ISO 23953 (2015) "Refrigerated display cabinets” in two parts (“Part 1 : Vocabulary” and “Part 2: Classification, requirements and test methods”).
• Refrigerated display cases are typically composed of a thermally insulated structure, elements ensuring the manufacture and distribution (local or remote) of cold, and shelves allowing the presentation and storage of foodstuffs, as shown in figure 1. They can be vertical or horizontal, closed by glass doors or open, with positive cold or negative cold.
• Food cooling of plant or animal products in refrigerated enclosures is usually achieved by forced air convection due to its relatively low cost and adaptability to all kinds of products compared to other cooling techniques.
• this air is generally dry, because the humidity condenses on the cold walls as well as at the level of the evaporator.
• the forced convection of dry air exacerbates the drying out of the products, at least on the surface, leading to an irreversible alteration of their organoleptic properties and a non-optimal shelf life.
• very fine droplets means droplets with a diameter typically between 1 ⁇ m and 10 ⁇ m.
• these droplets can be produced by piezoelectric elements which are also called “nebulizers"; such a device is described for example in EP 0 691 162 (IMRA Europe). This gives a mist blanket that does not wet surrounding surfaces.
• trigger designates a wetting type fog generator, composed of larger droplets which evaporate less quickly. It is generally undesirable to wet wet or dry food products intended for sale.
• WO 2014/023907 describes a stall with a substantially horizontal display surface, provided with spray nozzles which spread a layer of mist over the product display surface; in such a device, the layer of fog floats in the air, envelops the products displayed for sale, but evaporates before falling to the ground.
• MFVs open on an upper horizontal face are known; they are typically in the form of a box open on their upper face, which can be closed by a glass door.
• thermal confinement can be achieved naturally by means of cold air, heavier than hot air, which remains confined by the side walls of the box.
• this confined cold air does not tend to escape significantly through the upper opening.
• Such furniture is described in FR 2434601 (Bosshard).
• the situation is more complex in the case of showcases open on a vertical face.
• the geometry of such a refrigerated cabinet represents a technical challenge. Indeed the aforementioned vertical face defines an opening which is certainly advantageous, because it allows immediate apprehension of the products by the consumer.
• the cold air in this case necessarily tends to escape, in particular by gravity, through this front opening. Therefore, unless additional means are provided, the temperature in the showcase tends to rise undesirably.
• Different types of air curtains are known, which can in particular be single, double, triple, symmetrical, asymmetrical; they are sized according to the length of the opening to be covered, and according to the temperature difference to be maintained between the interior volume of the cabinet and the external environment.

• the orifices 84 are aligned parallel to the main axis Y82. This means that the different angles a84 are identical for each of these orifices. On the other hand, in the variant of FIG. 13, the orifices are staggered along the main axis Y82'.
• FIGs 14 and 15 illustrate a variant embodiment, in which the diffusion tube 82 is fed, not through a single intermediate conduit 81 as in Figure 7, but by two conduits 810 and 811.

Indeed, this solution allows an easier and more discreet integration in a piece of furniture where the space constraint is important. For example, it may be more advantageous to drill, in this piece of furniture, two small diameter holes for each intermediate duct 810 and 811, than a single larger diameter hole.

• this orifice 842 is provided substantially equidistant from orifices 840 and 841.
• Figures 16 and 17 have specific advantages, compared to the arrangement shown in Figures 14 and 15. Indeed the applicant has found that the fact of providing additional orifices 840 841, as well as 842 where appropriate, makes it possible to significantly reduce the so-called dead zones. The latter correspond to regions of the showcase, in which the density of nebulization is insufficient. It will be noted, with particular reference to FIGS. 2 and 3 above, that it is also advantageous to provide an orifice facing the outlet of the single diffusion pipe 81. It will also be noted that the applicant has also observed that this reduction dead zones is not proportional to the number of additional orifices made in the diffusion tube. Indeed, if we add still other orifices compared to those of figure 17, we note that the volume of these dead zones has on the contrary a tendency to increase again.
