Description

Mât de diffusion d'un brouillard de gouttelettes comprenant un déflecteur  Mast for diffusing a fog of droplets including a deflector
L'invention concerne les installations de diffusion d'un brouillard de gouttelettes nébulisé sur des produits. The invention relates to installations for diffusing a fog of nebulized droplets onto products.
On connaît du document WO 2010/106276 au nom de la demanderesse une telle installation associée à un étalage d'exposition de produits alimentaires utilisé dans des lieux de vente et comprenant des diffuseurs qui projettent un brouillard de gouttelettes d'eau au-dessus des produits. Une telle installation préserve la fraîcheur des produits, améliore leur aspect sur le présentoir et favorise leur vente.  Document WO 2010/106276, in the name of the applicant, discloses such an installation associated with a display of food products used in sales premises and comprising diffusers that project a mist of water droplets over the products. . Such an installation preserves the freshness of the products, improves their appearance on the display and promotes their sale.
L'installation comprend notamment un mât portant un bouchon à son extrémité supérieure. Le bouchon présente des conduits internes venant en coïncidence avec des orifices du mât et ayant des faces de forme courbe assurant l'orientation du jet vers le bas afin qu'il se répande sur les produits.  The installation includes a mast with a cap at its upper end. The plug has internal conduits coinciding with the holes of the mast and having curved faces ensuring the orientation of the jet downwards so that it spreads over the products.
En dépit de ses nombreux avantages, un tel bouchon est susceptible d'être amélioré. En effet, les faces courbes des conduits rendent sa fabrication relativement longue, difficile et donc coûteuse. De plus, la quantité de matière que le bouchon incorpore pour délimiter toutes ces faces en fait une pièce massive. Cette quantité de matière augmente elle aussi le prix de revient du bouchon. De plus, si le bouchon est mis en mouvement par des moyens d'entraînement, ceux-ci doivent être dimensionnés à la mesure de la masse à mouvoir.  Despite its many advantages, such a plug is likely to be improved. Indeed, the curved faces of the ducts make its manufacture relatively long, difficult and therefore expensive. In addition, the amount of material that the cap incorporates to delineate all these faces makes it a massive piece. This quantity of material also increases the cost price of the stopper. In addition, if the cap is moved by drive means, they must be sized to the extent of the mass to move.
Un but de l'invention est de fournir un bouchon tout aussi efficace mais ne présentant pas ces inconvénients.  An object of the invention is to provide a cap that is equally effective but does not have these disadvantages.
A cet effet, on prévoit selon l'invention un mât de diffusion d'un brouillard de gouttelettes qui présente au moins une ouverture allongée parallèlement à un axe principal du mât, et comprend une paroi plane apte à s'étendre transversalement à l'axe, entre une partie principale du mât et l'ouverture, en étant située d'un même côté de l'axe que cette dernière et en ménageant une communication entre la partie principale et l'ouverture à travers le mât.  For this purpose, according to the invention, there is provided a droplet mist diffusion mast which has at least one elongate opening parallel to a main axis of the mast, and comprises a flat wall capable of extending transversely to the axis. , between a main part of the mast and the opening, being located on the same side of the axis as the latter and by providing a communication between the main part and the opening through the mast.
La paroi forme un déflecteur qui oriente le flux de gouttelettes en amont des ouvertures pour qu'il sorte du mât en étant dirigé vers le bas et les produits à rafraîchir. Le mât muni d'une telle paroi est particulièrement simple à réaliser et peut présenter une masse peu importante. La forme allongée des ouvertures favorise également la diffusion du jet de brouillard vers le bas et les produits en coopération avec la paroi.  The wall forms a deflector which directs the flow of droplets upstream of the openings so that it emerges from the mast while being directed downwards and the products to be refreshed. The mast provided with such a wall is particularly simple to produce and may have a small mass. The elongate shape of the openings also promotes the diffusion of the fog jet downwards and the products in cooperation with the wall.
De préférence, la paroi est apte à s'étendre perpendiculairement à l'axe.  Preferably, the wall is adapted to extend perpendicularly to the axis.
En effet, bien que la paroi puisse être configurée pour être inclinée par rapport à l'axe, on obtient de bons résultats lorsqu'elle lui est perpendiculaire. Avantageusement, les ouvertures sont au moins au nombre de deux. Indeed, although the wall can be configured to be inclined relative to the axis, we obtain good results when it is perpendicular. Advantageously, the openings are at least two in number.
De préférence, le mât comprend un montant présentant l'ouverture et un bouchon comportant la paroi et monté mobile par rapport au montant.  Preferably, the mast comprises a post having the opening and a plug having the wall and mounted movable relative to the amount.
Ainsi, on peut certes prévoir de fixer la paroi directement au montant du mât portant la ou les ouvertures, mais il est avantageux que la paroi fasse partie d'un bouchon distinct du montant et mobile, par exemple amovible, par rapport à ce dernier. On facilite en effet ainsi la fabrication de l'ensemble.  Thus, it is certainly possible to fix the wall directly to the post of the mast carrying the opening or openings, but it is advantageous that the wall is part of a separate plug of the upright and movable, for example removable, relative thereto. In fact, the manufacture of the assembly is facilitated.
De préférence, le bouchon est monté rotatif par rapport au montant.  Preferably, the plug is rotatably mounted relative to the amount.
On peut prévoir que le bouchon est apte à obturer l'ouverture ou l'une au moins des ouvertures, de préférence toutes les ouvertures simultanément.  It can be provided that the plug is able to close the opening or at least one of the openings, preferably all the openings simultaneously.
Ainsi, le même bouchon peut servir à empêcher la diffusion par l'une des ouvertures voire par toutes les ouvertures du mât.  Thus, the same plug can be used to prevent the diffusion by one of the openings or by all the openings of the mast.
On peut également prévoir que le bouchon est apte à obturer l'une au moins des ouvertures sans obturer simultanément une autre au moins des ouvertures.  It is also possible that the cap is able to close at least one of the openings without simultaneously closing at least one other opening.
Ainsi, le bouchon sert aussi à sélectionner la ou les ouvertures du mât servant à diffuser le brouillard en empêchant la diffusion par la ou les autres ouvertures. Thus, the cap is also used to select the opening or openings of the mast for diffusing the fog by preventing diffusion by the other opening or openings.
Avantageusement, le bouchon présente une ouverture latérale apte à s'étendre simultanément en regard d'au moins deux des ouvertures allongées. Advantageously, the plug has a lateral opening able to extend simultaneously opposite at least two of the elongated openings.
On peut prévoir que le bouchon présente une face interne cylindrique.  It can be provided that the plug has a cylindrical inner face.
Ainsi, le bouchon est particulièrement simple à fabriquer.  Thus, the plug is particularly simple to manufacture.
De préférence, le bouchon présente une face d'extrémité interne de forme bombée dont un centre de courbure est situé d'un même côté de la face que l'intérieur du bouchon.  Preferably, the plug has an inner end face of curved shape, a center of curvature is located on the same side of the face as the inside of the plug.
Une telle face favorise elle aussi l'orientation du jet de brouillard vers le bas à la sortie des ouvertures en direction des produits.  Such a face also favors the orientation of the fog jet down at the outlet of the openings towards the products.
Avantageusement, la paroi présente un bord interne circonférentiel de forme circulaire centré sur l'axe.  Advantageously, the wall has a circumferential inner edge of circular shape centered on the axis.
Ce bord ménage une ouverture dans la paroi qui favorise également la bonne orientation du jet.  This edge provides an opening in the wall which also promotes the proper orientation of the jet.
Avantageusement, le rapport entre des rayons circonférentiels externe et interne de la paroi est compris entre 1 ,5 et 2,5, et vaut de préférence 2.  Advantageously, the ratio between outer and inner circumferential radii of the wall is between 1, 5 and 2.5, and is preferably 2.
On peut en effet prendre en compte deux angles relatifs au jet de brouillard ou à l'ensemble des jets de brouillard. Le premier, ici appelé angle a, mesure l'inclinaison moyenne du jet par rapport à la direction verticale. Le deuxième, ici appelé angle β, mesure l'angle formé par l'ensemble des jets en projection horizontale, le mât occupant le sommet de l'angle. En particulier, plus l'angle β est grand, plus large est la diffusion du jet sur les produits. Pour avoir une bonne diffusion des gouttelettes sur les produits, il importe que chacun de ces deux angles soit convenablement réglé. On réalise un bon compromis entre les valeurs de ces angles avec la fourchette précitée, particulièrement si le rapport vaut 2. On peut prévoir que le bouchon est réalisé d'un seul tenant, sans donc aucune partie amovible. Mais on peut aussi le réaliser comme un assemblage démontable de plusieurs pièces. We can indeed take into account two angles relating to the jet of fog or the set of fog jets. The first, here called an angle, measures the average inclination of the jet relative to the vertical direction. The second, here called angle β, measures the angle formed by the set of jets in horizontal projection, the mast occupying the top of the angle. In particular, the larger the angle β, the wider is the diffusion of the jet on the products. To have a good Droplet diffusion on products, it is important that each of these two angles is properly adjusted. A good compromise is made between the values of these angles with the aforementioned range, particularly if the ratio is 2. It can be provided that the cap is made in one piece, without any removable part. But we can also realize it as a dismountable assembly of several pieces.

On a illustré sur les figures une installation 2 de présentation de produits alimentaires. Il s'agit ici d'un meuble formant en l'espèce une table. Dans le présent exemple, ce meuble est utilisé dans un lieu de vente de produits.  There is illustrated in the figures a facility 2 for presenting food products. This is a piece of furniture forming in this case a table. In this example, this piece of furniture is used in a place of sale of products.
Les produits sont par exemple des produits frais 5 tels que des fruits et légumes. L'installation est également utilisable pour d'autres produits alimentaires frais tels que de la viande ou du poisson. Elle est aussi applicable à des produits alimentaires tels que du fromage et plus généralement à tout produit sensible au dessèchement, par exemple des fleurs. The products are, for example, fresh products such as fruits and vegetables. The facility can also be used for other fresh food products such as meat or fish. It is also applicable to food products such as cheese and more generally to any product sensitive to drying, for example flowers.
Le meuble forme ici un présentoir et comprend en partie supérieure un étalage 6 de forme rectangulaire en plan. Le présentoir comprend une paroi de fond et est ouvert en partie supérieure de sorte que les produits peuvent être observés ou pris par le public passant aux abords du présentoir.  The piece of furniture here forms a display and comprises in the upper part a display 6 of rectangular shape in plan. The display includes a bottom wall and is open at the top so that the products can be viewed or picked up by the public passing by the display stand.
Le meuble comprend des moyens pour la diffusion d'un brouillard de gouttelettes d'eau nébulisée, au-dessus des produits et jusqu'à ceux-ci afin d'en préserver la fraîcheur. Ces moyens comprennent un mât vertical 8 et un équipement 11 permettant la génération du brouillard de gouttelettes d'eau et son acheminement jusqu'au mât. Cet équipement comprend notamment un coffret d'alimentation électrique qui alimente en courant un générateur de brouillard. Ce dernier comprend un ou plusieurs émetteurs d'ultrasons équipés par exemple d'une buse de concentration acoustique servant à la production du brouillard formé par des gouttelettes d'eau nébulisée en suspension dans un flux d'air. Le générateur est alimenté en eau par un moyen adapté. Un tel générateur est connu en lui- même notamment du document FR-2 788 706. L'installation comprend des conduits 10 au moyen desquels le brouillard produit par le ou les générateurs est transmis jusqu'au mât, à une extrémité axiale inférieure de ce dernier. L'ensemble est pourvu d'un boîtier de commande non illustré permettant de commander et de régler le fonctionnement du meuble. Le boîtier permet notamment de régler la vitesse de ventilation, c'est-à-dire la vitesse de l'air formant une partie du brouillard, la puissance de nébulisation et d'autres paramètres de la machine (cycle, seuil de sécurité, etc.).  The furniture includes means for the diffusion of a fog of nebulized water droplets, above the products and up to them in order to preserve the freshness. These means comprise a vertical mast 8 and equipment 11 for generating the mist of water droplets and its routing to the mast. This equipment includes a power supply box that supplies power to a fog generator. The latter comprises one or more ultrasonic transmitters equipped for example with an acoustic concentration nozzle for the production of mist formed by nebulized water droplets suspended in an air flow. The generator is supplied with water by a suitable means. Such a generator is known in itself from FR-2 788 706. The installation comprises ducts 10 by means of which the fog produced by the generator or generators is transmitted to the mast at a lower axial end thereof. latest. The assembly is provided with an unillustrated control box for controlling and adjusting the operation of the furniture. The housing allows in particular to adjust the ventilation speed, that is to say the speed of the air forming part of the fog, the nebulization power and other parameters of the machine (cycle, safety threshold, etc. .).
Nous allons maintenant décrire plus en détails le mât 8 qui comprend dans le présent exemple un montant 12 et un bouchon 14 relié au montant.  We will now describe in more detail the mast 8 which comprises in the present example an amount 12 and a plug 14 connected to the amount.
Le montant 12 a ici une forme allongée rectiligne dont l'axe longitudinal 16 s'étend suivant la direction verticale. Le montant 12 présente une paroi latérale cylindrique 18 à section circulaire dans un plan perpendiculaire à l'axe. La paroi présente des ouvertures 20 allongées de préférence suivant la direction verticale c'est-à-dire celle de l'axe 16. Les ouvertures sont ici au nombre de trois mais on pourrait prévoir un nombre d'ouvertures égal à 1 , 2, 4 ou supérieur. Les ouvertures sont identiques entre elles et régulièrement espacées sur un demi-tour autour de l'axe 16. Elles s'étendent toutes à la même hauteur. Ces caractéristiques des ouvertures sont ici données à titre d'exemple et sont à adapter au cas par cas selon les résultats recherchés. Le montant est ouvert à son extrémité axiale supérieure 22. The amount 12 here has a rectilinear elongated shape whose longitudinal axis 16 extends in the vertical direction. The amount 12 has a cylindrical side wall 18 with a circular section in a plane perpendicular to the axis. The wall has openings 20 elongated preferably in the vertical direction that is to say that of the axis 16. The openings here are three in number but could be expected a number of openings equal to 1, 2, 4 or higher. The openings are identical to each other and regularly spaced a half turn around the axis 16. They all extend to the same height. These characteristics of openings are here given by way of example and are to be adapted case by case according to the desired results. The amount is open at its upper axial end 22.
Le bouchon 14 présente une forme générale à symétrie de révolution autour de son axe principal qui est l'axe 16 lorsque le bouchon est reçu dans le montant.  The plug 14 has a generally symmetrical shape of revolution about its main axis which is the axis 16 when the plug is received in the amount.
Le bouchon 14 comprend une paroi latérale cylindrique 24 à section circulaire dans un plan perpendiculaire à l'axe 16. Cette paroi présente un épaulement 26 situé environ à mi-distance des extrémités axiales inférieure 28 et supérieure 30 du bouchon. De la sorte, la face cylindrique externe 32 de la paroi 24 présente un plus petit diamètre dans sa portion inférieure située sous l'épaulement que dans sa portion supérieure située au-dessus. L'épaulement, en revanche, n'est pas visible à l'intérieur du bouchon si bien que la face interne cylindrique 34 à section circulaire de la paroi 24 présente un diamètre inchangé sur toute sa hauteur de l'une à l'autre des extrémités axiales. Cette face délimite une cavité interne 37 du bouchon.  The plug 14 comprises a cylindrical side wall 24 of circular section in a plane perpendicular to the axis 16. This wall has a shoulder 26 located approximately halfway between the lower axial ends 28 and 30 of the cap. In this way, the outer cylindrical face 32 of the wall 24 has a smaller diameter in its lower portion located under the shoulder than in its upper portion located above. The shoulder, on the other hand, is not visible inside the plug so that the cylindrical inner face 34 with circular section of the wall 24 has a diameter that is unchanged over its entire height from one to the other of the axial ends. This face delimits an internal cavity 37 of the plug.
Dans sa portion inférieure, la paroi latérale 24 présente une fenêtre ou ouverture 36 délimitée par des bords supérieur et inférieur inscrits dans des plans perpendiculaires à l'axe 16 et par des bords latéraux rectilignes parallèles de préférence à l'axe 16. La fenêtre 36 s'étend sur environ un demi-tour autour de l'axe 16 et met en communication la cavité 37 avec l'extérieur. La fenêtre 36 présente une hauteur, parallèlement à l'axe, en l'espèce supérieure ou égale à la hauteur des ouvertures 20. Elle présente par ailleurs une ouverture angulaire dans un plan perpendiculaire à l'axe 16 permettant aux trois ouvertures 20 de venir chacune intégralement et simultanément en regard de la fenêtre lorsque le bouchon est reçu dans le montant comme on le verra plus loin.  In its lower portion, the side wall 24 has a window or opening 36 delimited by upper and lower edges inscribed in planes perpendicular to the axis 16 and by rectilinear lateral edges parallel to the axis 16. The window 36 extends about a half turn around the axis 16 and communicates the cavity 37 with the outside. The window 36 has a height, parallel to the axis, in this case greater than or equal to the height of the openings 20. It also has an angular opening in a plane perpendicular to the axis 16 allowing the three openings 20 to come each integrally and simultaneously facing the window when the cap is received in the amount as will be seen later.
Le bouchon est obturé à son extrémité supérieure 30 par une paroi bombée 38 qui en l'espèce présente deux faces externe et interne sphériques concentriques dont le centre de courbure est situé du même côté de la paroi que le bouchon.  The plug is closed at its upper end 30 by a curved wall 38 which in this case has two concentric outer and inner spherical faces whose center of curvature is located on the same side of the wall as the plug.
Le bouchon comprend une paroi inférieure plane et plate 40 qui présente des faces supérieure et inférieure planes perpendiculaires à l'axe 16. Elle présente en l'espèce en plan une forme de demi rondelle délimitée notamment par des bords circonférentiels circulaires externe 42 et interne 44, tous deux concentriques à l'axe 16. La paroi est donc notamment évidée au voisinage de ce dernier. Elle présente également deux bords radiaux 46 reliant les extrémités des bords circulaires respectifs. La paroi 40 s'étend sur environ un demi-tour et, en l'espèce sur un demi-tour, autour de l'axe 16. La rondelle est fixée au bord inférieur de la paroi 24, au niveau de son extrémité axiale inférieure 28, par exemple par des points de soudure 48 illustrés à la figure 4. Si l'on considère le côté du bouchon situé à droite de l'axe 16 sur les figures 5 et 6 et dans lequel s'étend la fenêtre 36, on voit que la rondelle s'étend elle aussi de ce côté de l'axe. La rondelle est ici contigue à la fenêtre 36. The plug comprises a flat, flat bottom wall 40 which has planar upper and lower faces perpendicular to the axis 16. In the present case, it presents in the form of a semicircle shape defined in particular by circular outer circumferential 42 and internal 44 edges. , both concentric with the axis 16. The wall is thus recessed in the vicinity of the latter. It also has two radial edges 46 connecting the ends of the respective circular edges. The wall 40 extends over about half a turn and, in this case about a half turn, about the axis 16. The washer is fixed to the lower edge of the wall 24, at its lower axial end. 28, for example by welding points 48 illustrated in FIG. 4. Considering the side of the plug located to the right of the axis 16 in FIGS. 5 and 6 and in which the window 36 extends, we see that the washer also extends on this side of the axis. The washer is here contiguous to the window 36.
Le bouchon est dimensionné afin qu'il puisse être inséré par son extrémité axiale inférieure à travers l'extrémité supérieure du montant pour se loger dans ce dernier. Le bouchon est ainsi mis en appui par l'épaulement 26 sur le bord de la paroi 18. Le diamètre de la partie inférieure de la face externe 32 est choisi pour être légèrement inférieur au diamètre interne de la paroi 18. Par ailleurs, dans sa partie supérieure, la face 32 a le même diamètre que la face externe de la paroi 18. Il s'agit d'un montage amovible du bouchon sur le montant.  The cap is sized so that it can be inserted through its lower axial end through the upper end of the upright to accommodate it. The plug is thus supported by the shoulder 26 on the edge of the wall 18. The diameter of the lower portion of the outer face 32 is chosen to be slightly smaller than the internal diameter of the wall 18. Moreover, in its upper part, the face 32 has the same diameter as the outer face of the wall 18. This is a removable assembly of the cap on the amount.
Le bouchon et le montant sont agencés de sorte que, une fois assemblés de cette façon comme illustré à la figure 6, le bouchon est mobile en rotation par rapport au montant autour de l'axe 16. La paroi 40 s'étend alors perpendiculairement à l'axe entre la fenêtre 36 au-dessus et la partie principale 13 du mât au-dessous, reliée à l'équipement et qui s'étend en amont du bouchon par référence au flux de brouillard. Cette même paroi 40 ménage une communication entre l'équipement 11 et la partie principale 13 du mât d'une part et la fenêtre 36 d'autre part. Elle s'étend intégralement entre la partie principale du mât, partie amont, et l'extrémité inférieure amont des ouvertures 36 et 20.  The stopper and the upright are arranged so that, when assembled in this manner as shown in FIG. 6, the stopper is rotatable relative to the upright around the axis 16. The wall 40 then extends perpendicularly to the axis between the window 36 above and the main part 13 of the mast below, connected to the equipment and which extends upstream of the plug with reference to the flow of fog. This same wall 40 provides a communication between the equipment 11 and the main part 13 of the mast on the one hand and the window 36 on the other hand. It extends completely between the main part of the mast, upstream part, and the upstream lower end of the openings 36 and 20.
Il existe une position du bouchon par rapport au montant, illustrée à la figure 6, dans laquelle la fenêtre 36 s'étend en regard de l'intégralité des trois ouvertures 20 simultanément, du même côté de l'axe que celles-ci.  There is a position of the plug with respect to the upright, illustrated in FIG. 6, in which the window 36 extends opposite all the three openings 20 simultaneously, on the same side of the axis as these.
Lorsque l'équipement génère du brouillard, le flux de brouillard montant dans le mât contourne donc la paroi 40, par la gauche sur la figure 6, puis pénètre dans la cavité 37 pour passer par la fenêtre 36 et sortir du mât à travers chacune des ouvertures 20. Une dépression est ainsi crée par la paroi 40 à la base des ouvertures. En sortie de mât, les trois jets de brouillard respectifs sont dirigés vers le bas en étant inclinés par rapport à la direction verticale d'un angle a comme illustré à la figure 8. Lorsqu'on observe l'installation en vue de dessus comme sur la figure 9, les jets forment un ensemble s'étendant sur un angle dont le sommet est occupé par l'axe 16 et dont la demi-valeur vaut β.  When the equipment generates fog, the fog flow rising in the mast thus bypasses the wall 40, on the left in FIG. 6, then enters the cavity 37 to pass through the window 36 and exit the mast through each of the openings 20. A depression is thus created by the wall 40 at the base of the openings. At the exit of the mast, the three respective fog jets are directed downwards by being inclined with respect to the vertical direction of an angle α as illustrated in FIG. 8. When observing the installation in plan view as on 9, the jets form an assembly extending over an angle whose apex is occupied by the axis 16 and whose half value is equal to β.
On désigne respectivement par Re et Ri les rayons des bords 42 et 44 de la rondelle. On choisit en l'espèce le rapport Re/Ri comme égal à 2. Cette valeur donne en effet un bon compromis entre les angles a et β et permet d'avoir des jets particulièrement bien orientés vers les produits. On définit ici par h la distance séparant la paroi 40 et le sommet de la face interne de la paroi bombée 38. La distance h influence elle aussi la géométrie du jet de brouillard.  Re and Ri denote respectively the radii of the edges 42 and 44 of the washer. In the present case, the ratio Re / Ri is chosen to be equal to 2. This value indeed gives a good compromise between the angles α and β and makes it possible to have jets particularly well oriented towards the products. Here, the distance separating the wall 40 from the top of the inner face of the curved wall 38 is defined by h. The distance h also influences the geometry of the fog jet.
Le bouchon mobile en rotation peut aussi occuper une position dans laquelle la fenêtre 36 s'étend toute entière du côté de l'axe opposé à celui occupé par les ouvertures 20. Dans ce cas, la paroi 24 obture toutes les ouvertures 20 si bien que la partie d'extrémité supérieure du mât est entièrement obturée par le bouchon. Le mât ne diffuse donc pas de brouillard. The rotatable plug may also occupy a position in which the window 36 extends entirely on the side of the axis opposite to that occupied by the openings 20. In this case, the wall 24 closes all the openings 20 so that the upper end portion of the mast is completely closed by the plug. The mast does not spread fog.
On peut également orienter le bouchon autour de l'axe 16 de façon à mettre en coïncidence avec la fenêtre 36 seulement une ou deux des ouvertures 20, la paroi 24 obturant la ou les autres. On sélectionne ainsi la ou les ouvertures qui assurent la diffusion du brouillard, de sorte qu'on choisit la zone de l'étalage qui reçoit les gouttelettes.  It is also possible to orient the cap around the axis 16 so as to coincide with the window 36 only one or two of the openings 20, the wall 24 closing the other (s). This selects the opening or openings that ensure the diffusion of fog, so that we choose the area of the display that receives the droplets.
Les ouvertures 20 ont par exemple une hauteur de 20 millimètres et une largeur de 10 millimètres. Il est préférable que leur hauteur ne dépasse pas 20 millimètres pour ne pas trop diminuer la vitesse de sortie du brouillard. Ces dimensions sont choisies notamment en fonction du diamètre du montant. Les plans de symétrie verticale de deux ouvertures consécutives forment un angle de 65° en l'espèce. On peut donner au bouchon un diamètre externe d'environ 30 millimètres. Le rayon Ri vaut ici environ 7 millimètres.  The openings 20 have for example a height of 20 millimeters and a width of 10 millimeters. It is preferable that their height does not exceed 20 millimeters so as not to decrease the speed of the fog too much. These dimensions are chosen in particular according to the diameter of the amount. The planes of vertical symmetry of two consecutive openings form an angle of 65 ° in this case. The plug can be given an outer diameter of about 30 millimeters. The radius Ri is here about 7 millimeters.
Le mode de réalisation présenté ici a pour avantage d'être particulièrement simple. Mais la forme du bouchon et celle du déflecteur pourront être adaptées en fonction des dimensions du montant, de celles des fentes, de leur position, du résultat recherché en termes de géométrie du jet (les angles alpha et bêta) et en termes de vitesse et de concentration des gouttelettes.  The embodiment presented here has the advantage of being particularly simple. But the shape of the plug and that of the baffle may be adapted according to the dimensions of the amount, those of the slots, their position, the desired result in terms of the geometry of the jet (the angles alpha and beta) and in terms of speed and concentration of the droplets.
Bien entendu, on pourra apporter à l'invention de nombreuses modifications sans sortir du cadre de celle-ci.  Of course, we can bring to the invention many changes without departing from the scope thereof.
L'installation pourra être dotée de plusieurs mâts diffusant du brouillard sur différentes parties de l'étalage.  The installation may be equipped with several masts scattering fog on different parts of the display.
Le mât ou l'un des mâts peut être monté rotatif par rapport à l'étalage.  The mast or one of the masts may be rotatably mounted relative to the display.
On peut prévoir que le mât comprend des moyens permettant le réglage de la hauteur des ouvertures 20 et du bouchon par rapport à l'étalage.  It can be provided that the mast comprises means for adjusting the height of the openings 20 and the plug relative to the display.
Le mât peut être non rectiligne. Son axe peut être incliné par rapport à la direction verticale.  The mast may be non-rectilinear. Its axis can be inclined relative to the vertical direction.
Toutes les valeurs dimensionnelles données ici ne le sont qu'à titre d'exemple et d'autres dimensions peuvent naturellement être envisagées.  All dimensional values given here are only exemplary and other dimensions can of course be considered.
L'installation ne forme pas nécessairement un meuble. Elle peut être utilisée dans un lieu de stockage ou de production, par exemple un lieu de vinification de vin ou d'affinage de fromages. Elle peut constituer une installation de fabrication et/ou de conditionnement. L'installation peut aussi servir à la désinfection ou à l'humidification de produits ou de volumes, par exemple de produits circulant sur un tapis, notamment sur une chaîne de fabrication ou de conditionnement. The installation does not necessarily form a piece of furniture. It can be used in a place of storage or production, for example a place of wine making or cheese refining. It can constitute a manufacturing facility and / or packaging. The installation can also be used for the disinfection or humidification of products or volumes, for example products circulating on a carpets, especially on a production or packaging line.
