Description

"Meuble frigorifique, notamment meuble vertical, du type à rideaux d'air froid à l'avant du meuble"."Refrigeration unit, in particular vertical unit, of the cold air curtain type at the front of the unit".
L'invention concerne un meuble frigorifique, notamment meuble vertical, du type à rideaux d'air froid à l'avant du meuble devant les denrées exposées, comprenant essentiellement une partie haute de sortie de l'air froid et un dispositif de reprise d'air disposé au niveau du bord supérieur de la paroi avant de la cuve du meuble et comportant des ouvertures de reprise d'air situées dans un plan sensiblement horizontal, sous l'effet d'un dispositif de ventilateur prévu dans ladite cuve. Les meubles frigorifiques de ce type qui sont connus, présentent l'inconvénient majeur que le dispositif de reprise horizontal entraîne une augmentation relativement importante de la largeur du meuble, au-delà de son espace utile d'exposition des denrées.The invention relates to a refrigeration cabinet, in particular vertical cabinet, of the type with cold air curtains at the front of the cabinet in front of the exposed foodstuffs, essentially comprising a high part for the outlet of cold air and a device for taking up air disposed at the upper edge of the front wall of the cabinet tank and comprising air return openings located in a substantially horizontal plane, under the effect of a fan device provided in said tank. Refrigerators of this type which are known, have the major drawback that the horizontal recovery device causes a relatively large increase in the width of the cabinet, beyond its useful space for displaying foodstuffs.
La présente invention a pour but de proposer un meuble frigorifique qui pallie l'inconvénient qui vient d'être énoncé.The present invention aims to provide a refrigeration unit which overcomes the drawback which has just been stated.
Pour atteindre ce but, un meuble frigorifique selon l'invention est caractérisé en ce que le dispositif de reprise d'air comporte en plus des ouvertures de reprise situées dans un plan sensiblement horizontal des ouvertures de reprise d'air situées dans un plan sensiblement vertical . Selon une caractéristique de l'invention, les ouvertures de reprise horizontale et verticale font partie de persiennes respectivement horizontales et verticales et une surface inclinée d' anti-décollement du rideau d'air est prévue entre les deux persiennes de reprise d'air.To achieve this object, a refrigeration unit according to the invention is characterized in that the air intake device further comprises return openings located in a substantially horizontal plane air return openings located in a substantially vertical plane . According to a characteristic of the invention, the horizontal and vertical return openings are part of horizontal and vertical louvers respectively and an inclined anti-detachment surface of the air curtain is provided between the two air return louvers.
L'invention sera mieux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement dans la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels :The invention will be better understood, and other aims, characteristics, details and advantages thereof will appear more clearly in the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating an embodiment of the invention and in which:

-la figure 6 est une vue similaire à la figure 4 d'une autre version de réalisation d'un support de persiennes selon l'invention.FIG. 6 is a view similar to FIG. 4 of another version of an embodiment of a louver support according to the invention.
Sur la figure 1 qui montre en une vue en perspective un meuble frigorifique vertical selon l'invention, les numéros de référence 1 à 4 illustrent respectivement la paroi arrière du meuble, la partie formant le toit, la partie basse constituant la cuve et une pluralité d'étagères, verticalement superposées et destinées chacune à porter des denrées réfrigérées ou surgelées. Les étagères sont portées par la paroi arrière du meuble. La meuble est équipé d'une unité de refroidissement 6 du type échangeur/et vaporateur et un certain nombre de ventilateurs 7, qui sont logés dans la cuve, de la manière indiquée schématiquement sur les figures 1 et 2. Les ventilateurs engendrent les écoulements d'air froid tels que symbolisés par des flèches sur la figure 1 et montrés plus clairement sur la figure 2, de la manière connue en soi . On constate que 1 ' air froid monte à l'intérieur de la paroi arrière 1 jusqu'à l'avant 9 du toit 2 où il sort en 10 pour former un rideau d'air froid 11 à l'avant du meuble devant les denrées schématiquement indiqué en 14. La figure 2 montre également qu'une partie de l'air se sépare de l'écoulement verticalement montant pour être distribué aux étagères en passant au-dessus des denrées schématisés en 14 sur les figures 1 et 2 et joindre le rideau vertical 11. Le rideau d'air froid est repris en bas du meuble par un dispositif de reprise 15 au niveau du bord supérieur de la paroi avant de façade 16 de la cuve 3, sous l'effet des ventilateurs 7.In Figure 1 which shows in a perspective view a vertical refrigeration unit according to the invention, the reference numbers 1 to 4 respectively illustrate the rear wall of the cabinet, the part forming the roof, the bottom part constituting the tank and a plurality shelves, vertically superimposed and each intended to carry refrigerated or frozen food. The shelves are carried by the rear wall of the cabinet. The cabinet is equipped with a cooling unit 6 of the exchanger / and evaporator type and a certain number of fans 7, which are housed in the tank, as shown diagrammatically in FIGS. 1 and 2. The fans generate the flows d air as symbolized by arrows in Figure 1 and shown more clearly in Figure 2, as known per se. It can be seen that the cold air rises inside the rear wall 1 to the front 9 of the roof 2 where it exits at 10 to form a curtain of cold air 11 at the front of the furniture in front of the foodstuffs schematically indicated in 14. FIG. 2 also shows that part of the air separates from the vertically rising flow to be distributed to the shelves by passing over the goods schematized at 14 in FIGS. 1 and 2 and joining the vertical curtain 11. The curtain of cold air is taken up at the bottom of the cabinet by a recovery device 15 at the upper edge of the front wall 16 of the tank 3, under the effect of the fans 7.
La figure 2 illustre la présence d'un second rideau d'air indiqué en 18, extérieur, c'est-à-dire devant le rideau d'air froid 11. Ce rideau est constitué d'air ambiant pris en haut du meuble par un ventilateur 20 et rejeté en bas dans l'allée à l'avant du meuble. Le rideau secondaire 18 n'est pas refroidi.FIG. 2 illustrates the presence of a second air curtain indicated at 18, exterior, that is to say in front of the cold air curtain 11. This curtain consists of ambient air taken from the top of the cabinet by a fan 20 and rejected down the aisle at the front of the cabinet. The secondary curtain 18 is not cooled.
Les figures 3 à 6 illustrent spécifiquement le dispositif 15 de reprise d'air froid du rideau 11. Ce dispositif sera maintenant décrit plus en détails en se référant à ces figures.Figures 3 to 6 specifically illustrate the device 15 for recovering cold air from the curtain 11. This device will now be described in more detail with reference to these figures.
Comme on le voit notamment sur la figure 3 , le dispositif de reprise de l'air froid comporte essentiellement une persienne de reprise horizontale 22, c'est-à-dire pourvue d'ouvertures 23 situées dans un plan sensiblement horizontal et en forme de deux rangées de fentes alignées et une persienne verticale 24 comportant des ouvertures 25 disposées dans un plan sensiblement vertical et également en forme de deux rangées de fentes.As seen in particular in Figure 3, the cold air intake device essentially comprises a horizontal return louver 22, that is to say provided with openings 23 located in a substantially horizontal plane and shaped two rows of aligned slots and a vertical louver 24 having openings 25 arranged in a substantially vertical plane and also in the form of two rows of slots.
Comme on le voit sur la figure 2, les distances des deux reprises verticale 22 et horizontale 24 imposent une séparation du rideau d'air en écoulements Fa et Fb.As can be seen in FIG. 2, the distances of the two vertical 22 and horizontal 24 times require separation of the air curtain into flows Fa and Fb.
Selon une caractéristique importante de l'invention, le dispositif de reprise d'air froid comporte, entre les deux persiennes horizontale 22 et verticale 24, une face inclinée 27, qui s'étend selon un angle de 45° par rapport aux plans horizontal et vertical. Grâce à cette face inclinée 27 les deux écoulements Fa et Fb recollent rapidement en aval des reprises de façon à obtenir une relaminarisation rapide. Selon une caractéristique avantageuse de l'invention, les persiennes horizontale et verticale sont supportées par une pluralité de pièces de support 28 réparties uniformément le long de l'axe longitudinal du meuble . La figure 5 est une vue en perspective d'une telle pièce de support 28. On constate qu'elle comporte une partie médiane 29 en forme d'une plaque qui s'étend perpendiculairement à 1 ' axe longitudinal du meuble et dont l'arête arrière 30 orientée vers la cuve est arquée et présente la forme courbe bien visible sur la figure 4. Le bord avant de la partie médiane 29 comporte des parties en saillie verticalement et horizontalement 31, 32 qui constituent des portions de support des lames 34 et 35 des persiennes horizontale et verticale. Entre ces deux portions de support 31 et 32 en saillie verticalement vers le haut et horizontalement vers l'extérieur est prévue une portion intermédiaire 37 en forme d'une traverse qui s'étend latéralement de part et d'autre de la partie intermédiaire 29, dans la direction de l'axe du meuble et présente une section transversale sensiblement en U renversé. C'est cette portion 37 qui sert de support d'un profilé 39 dont la face avant libre extérieure constitue la face inclinée 27 anti-décollement , qui est interposée entre les deux reprises horizontale et verticale du rideau d'air froid. Comme le montre la figure 4, le profilé 39 comporte, en saillie vers l'arrière deux ailettes 40 qui viennent en prise derrière les branches 41 de la traverse ou barrette de support 37 lorsque le profilé est mis en place entre les deux reprises horizontale et verticale. Il est encore à noter que, au niveau des arêtes longitudinales supérieure et inférieure, le profilé 39 présente des saillis recourbés 51 permettant la mise en place d'étiquettes non représentées.According to an important characteristic of the invention, the cold air intake device comprises, between the two horizontal louvers 22 and vertical 24, an inclined face 27, which extends in a 45 ° angle to the horizontal and vertical planes. Thanks to this inclined face 27 the two flows Fa and Fb quickly glue downstream of the recoveries so as to obtain a rapid relaminarization. According to an advantageous characteristic of the invention, the horizontal and vertical louvers are supported by a plurality of support pieces 28 distributed uniformly along the longitudinal axis of the piece of furniture. Figure 5 is a perspective view of such a support piece 28. We see that it has a middle portion 29 in the form of a plate which extends perpendicular to one longitudinal axis of the furniture and whose edge rear 30 oriented towards the tank is arched and has the curved shape clearly visible in Figure 4. The front edge of the middle part 29 has vertically and horizontally projecting parts 31, 32 which constitute support portions of the blades 34 and 35 horizontal and vertical louvers. Between these two support portions 31 and 32 projecting vertically upward and horizontally outward is provided an intermediate portion 37 in the form of a cross-member which extends laterally on either side of the intermediate part 29, in the direction of the axis of the furniture and has a substantially U-shaped cross section. It is this portion 37 which serves to support a profile 39 whose external free front face constitutes the inclined face 27 anti-detachment, which is interposed between the two horizontal and vertical recoveries of the curtain of cold air. As shown in FIG. 4, the profile 39 comprises, projecting towards the rear, two fins 40 which come into engagement behind the branches 41 of the cross member or support bar 37 when the profile is put in place between the two horizontal and vertical. It should also be noted that, at the level of the upper and lower longitudinal edges, the profile 39 has curved projection 51 allowing the placement of labels not shown.
Le support 28 comporte une partie formant pied 42 permettant sa fixation sur la paroi avant 16 de la cuve. Cette partie formant pied 42 fait saillie latéralement de part et d'autre de la partie médiane du support et présente, en section transversale, la forme d'un L dont la branche longue 43 vient s'appliquer et fixer contre la face interne de la paroi avant 16 de la cuve tandis que l'autre branche 44 prend appui sur la face supérieure sensiblement horizontale de la paroi de cuve. L'extrémité de la branche 44 est recourbée en 45 de façon à constituer une patte de fixation du support 28 sur la paroi avant de la cuve. Le support 28 est fixé sur la paroi avant de cuve par des vis 46 dont les trous de passage sont indiqués en 47 sur la figure 5.The support 28 comprises a part forming a foot 42 allowing it to be fixed to the front wall 16 of the tank. This part forming a foot 42 projects laterally on either side of the median part of the support and has, in cross section, the shape of an L whose long arm 43 is applied and fixed against the internal face of the front wall 16 of the tank while the other branch 44 bears on the substantially horizontal upper face of the tank wall. The end of the branch 44 is bent at 45 so as to constitute a bracket for fixing the support 28 on the front wall of the tank. The support 28 is fixed to the front wall of the tank by screws 46, the through holes of which are indicated at 47 in FIG. 5.
A son extrémité opposée au pied 42, la pièce de support 28 porte une barrette horizontale 49 d'appui des étagères ou plateaux 4 du meuble par l'intermédiaire d'un profilé intermédiaire 50 qui s'étend sur toute la longueur du meuble et constitue une paroi de limitation latérale de la persienne de reprise horizontale. L'autre paroi latérale de délimitation de la persienne est formée par le bord supérieur 51 du profilé anti-décollement avant 39. Le bord inférieur 51 constitue une face de délimitation latérale de la persienne de reprise verticale délimitée sur l'autre côté par une deuxième lamelle inférieure 35. Les lamelles sont insérées chacune dans une fente pratiquée dans le support . II est à souligner que la configuration spécifique des pièces de support 28, notamment en raison du bord arrière arqué permet un recollement immédiatement en aval des écoulements de reprise de façon qu'entre la reprise et les ventilateurs 7, il puisse s'établir un écoulement en spirale de l'air, les ventilateurs 7 étant orientés en conséquence . La figure 6 montre une autre version de réalisation du dispositif de reprise mixte de l'air, établi pour un meuble dont la paroi de cuve avant est rehaussée par un élément de façade supplémentaire 57. Dans ce cas la pièce de support des persiennes de reprise horizontale et verticale, qui présentent maintenant la référence 28' est identique à la pièce 28 dans sa portion de support proprement dite des persiennes, mais est configurée différemment dans sa partie inférieure de fixation à la cuve. Cette partie comporte maintenant dans sa partie avant une bride en forme d'un Z ayant une partie supérieure 59 de fixation de la paroi de façade de rehaussement 57, qui est suivi d'une portion en L 60 correspondant à la partie de pied en forme de L 42 de la pièce de support 28 et qui permet la fixation à la paroi avant de la cuve .At its end opposite the foot 42, the support piece 28 carries a horizontal bar 49 for supporting the shelves or trays 4 of the piece of furniture by means of an intermediate profile 50 which extends over the entire length of the piece of furniture and constitutes a lateral limitation wall of the horizontal recovery louver. The other lateral wall delimiting the louver is formed by the upper edge 51 of the front anti-separation profile 39. The lower edge 51 constitutes a side delimiting side of the vertical recovery louver delimited on the other side by a second lower strip 35. The strips are each inserted into a slot in the support. It should be emphasized that the specific configuration of the support pieces 28, in particular because of the arched rear edge, allows gluing immediately downstream of the return flows so that between the return and the fans 7, a flow can be established. in an air spiral, the fans 7 being oriented accordingly. Figure 6 shows another embodiment of the mixed air intake device, established for a piece of furniture whose front tank wall is enhanced by an additional facade element 57. In this case the support part of the return louvers horizontal and vertical, which now have the reference 28 ′ is identical to the part 28 in its portion of actual support for the shutters, but is configured differently in its lower part for fixing to the tank. This part now has in its front part a Z-shaped flange having an upper part 59 for fixing the raising facade wall 57, which is followed by an L-shaped portion 60 corresponding to the shaped foot part L 42 of the support piece 28 and which allows attachment to the front wall of the tank.
Le bord arrière orienté vers 1 ' intérieur de la cuve de la pièce de support 28', dans sa partie située juste en dessous de la portion de support de la persienne de reprise horizontale est réalisé sous forme d'une bride 61 qui s'étend sensiblement verticalement et permet la mise en place d'une plaque verticale 62 qui s'étend sur toute la longueur du meuble et établit en aval des reprises horizontale et verticale une cheminée 64 de recollement des écoulements de reprise, conduisant cet écoulement ainsi relaminarisé vers le bord arrière de sortie 68 de la pièce de support, qui est configuré comme le bord arrière 30 de la pièce de support 28 pour assurer l'établissement de l'écoulement en spirale de l'air entre le dispositif de reprise 15 et les ventilateurs 7.The rear edge oriented towards the inside of the tank of the support part 28 ′, in its part located just below the support portion of the horizontal recovery louver is produced in the form of a flange 61 which extends substantially vertically and allows the establishment of a vertical plate 62 which extends over the entire length of the piece of furniture and establishes downstream of the horizontal and vertical recoveries a chimney 64 for re-bonding the recovery flows, leading this flow thus relaminarized towards the rear outlet edge 68 of the support piece, which is configured as the rear edge 30 of the support piece 28 to ensure the establishment of the spiral flow of air between the recovery device 15 and the fans 7 .
Il ressort de la description qui précède, que grâce à la configuration des pièces de support, avec la face avant inclinée et le bord arrière spécifique, l'invention permet de réaliser une reprise d'air mixte, à savoir horizontale et verticale, assurant une réduction de la largeur du meuble tout en assurant un pouvoir de refroidissement excellent. Bien entendu de diverses modifications peuvent être apportées au meuble tel que décrit et représenté, sans sortir du cadre de l'invention. Ainsi les pièces de support des persiennes horizontale et verticale peuvent avoir toute autre forme appropriée, à condition de satisfaire aux deux exigences susmentionnées d'un décollement minimum entre les deux reprises et d'un recollement et d'une relaminarisation des écoulements d'air de reprise immédiatement en aval des deux reprises, et de l'établissement de la circulation en spirale de l'air entre la reprise et les ventilateurs de re-circulation de l'air vers le haut du meuble en passant par l'unité de refroidissement 6.It appears from the foregoing description that, thanks to the configuration of the support parts, with the inclined front face and the specific rear edge, the invention makes it possible to produce a mixed air intake, namely horizontal and vertical, ensuring a reduction of the width of the cabinet while ensuring excellent cooling power. Of course various modifications can be made to the furniture as described and shown, without departing from the scope of the invention. Thus, the support parts for the horizontal and vertical louvers can have any other suitable shape, provided that they meet the two aforementioned requirements of a minimum separation between the two occasions and a reassembly and a re-laminarization of the air flows of return immediately downstream of the two recoveries, and of the establishment of the spiral air circulation between the return and the air recirculation fans towards the top of the cabinet passing through the cooling unit 6 .
Il est encore à noter que les pièces de support 28 et 28' ont, en plus de la fonction qui vient d'être décrite, la fonction supplémentaire d'assurer la reprise des efforts des étagères ou plateaux où sont exposées les denrées et la transmission de ces efforts à la cuve. It should also be noted that the support pieces 28 and 28 ′ have, in addition to the function which has just been described, the additional function of ensuring the recovery of the efforts of the shelves or trays where the foodstuffs and the transmission are exposed. of these efforts at the tank.
