Description

La présente invention a pour objet un dispositif de cloisonnement réglable à volets mobiles pour appareil de production de froid, tel qu'un réfrigérateur par exemple, ce dispositif destiné à être placé dans la partie inférieure de l'enceinte réfrigérée telle que la cuve du réfrigérateur, permettant d'obtenir, dans le ou les compartiments inférieurs dans lesquels on désire conserver certains aliments particuliers (légumes) ou certaines boissons (vins), des températures sensiblement plus élevées que la température régnant dans le reste du réfrigérateur.The subject of the present invention is an adjustable partitioning device with movable shutters for a device for producing cold, such as a refrigerator for example, this device intended to be placed in the lower part of the refrigerated enclosure such as the tank of the refrigerator. , making it possible to obtain, in the lower compartment or compartments in which it is desired to store certain particular foods (vegetables) or certain drinks (wines), temperatures substantially higher than the temperature prevailing in the rest of the refrigerator.

En effet, il est intéressant d'avoir à sa disposition un réfrigérateur comportant un ou plusieurs compartiments dans lesquels la température peut avoir une valeur choisie entre +5° et +12° par exemple, alors que la température moyenne des autres compartiments, ou compartiments normalement réfrigérés, de la cuve du réfrigérateur est voisine de +5°. Une telle différenciation peut également être utile dans un congélateur où le compartiment bas, le moins froid peut servir à conserver des denrées moins froides.Indeed, it is advantageous to have at one's disposal a refrigerator comprising one or more compartments in which the temperature can have a value chosen between + 5 ° and + 12 ° for example, while the average temperature of the other compartments, or compartments normally refrigerated, the refrigerator bowl is around + 5 °. Such differentiation can also be useful in a freezer where the lower, less cold compartment can be used to store less cold food.

Afin d'obtenir dans le (ou les) compartiment inférieur d'un réfrigérateur (bac à légumes par exemple) des températures supérieures à +5°, il est connu de limiter la circulation d'air réfrigéré en isolant ces compartiments au moyen d'une cloison horizontale fixe de dimensions telles que ses bords soient très proches des parois avant et arrière de la cuve du réfrigérateur, empêchant ainsi l'air froid de descendre vers ces compartiments.In order to obtain temperatures in the lower compartment (s) of a refrigerator (vegetable drawer for example) of more than + 5 °, it is known to limit the circulation of refrigerated air by isolating these compartments by means of a fixed horizontal partition of dimensions such that its edges are very close to the front and rear walls of the tank of the refrigerator, thus preventing cold air from descending towards these compartments.

Il est également connu, par exemple par le brevet américain US-A-2 107 076 ou par le brevet américain US-A-2 006 046, d'avoir, dans une enceinte réfrigérée, un compartiment inérieur plus ou moins froid grâce à une cloison comportant des ouvertures qui peuvent être ouvertes ou fermées grâce à une seconde cloison dont le coulissement vient fermer les trous de la première.It is also known, for example by American patent US-A-2 107 076 or by American patent US-A-2 006 046, to have, in a refrigerated enclosure, an interior compartment more or less cold thanks to a partition comprising openings which can be opened or closed by means of a second partition, the sliding of which comes to close the holes of the first.

Encore un exemple de compartiment inférieur à température réglable est décrit dans le brevet anglais GB-A-2 017 888. Dans ce document la paroi 12 qui sépare les deux compartiments que l'on souhaite régler à des températures différentes comporte, vers l'arrière, des ouvertures 13 qui peuvent être fermées par une paroi mobile 14 manoeuvrée par une tirette 16. Lorsque les ouvertures 13 sont libérées, un peu d'air froid descend et le compartiment inférieur atteint sa température la plus froide. Mais il faut noter que ce dispositif ne permet pas une circulation réglable d'air par convection. En effet si de l'air froid peut descendre (la source froide est dans le compartiment supérieur) par les ouvertures 13, une quantité équivalente d'air réchauffé ne peut pas remonter vers le compartiment froid. Certes il existe à l'avant de l'appareil une mince fente (6 mm maximum) entre le bord de la paroi de séparation 12 de la contre-porte du réfrigérateur, mais cette fente est beaucoup trop petite par rapport aux dimensions des fentes 13 pour assurer une circulation par convection.Another example of a lower compartment with adjustable temperature is described in English patent GB-A-2,017,888. In this document, the wall 12 which separates the two compartments which it is desired to adjust at different temperatures comprises, towards the rear , openings 13 which can be closed by a movable wall 14 operated by a zipper 16. When the openings 13 are released, a little cold air descends and the lower compartment reaches its coldest temperature. But it should be noted that this device does not allow an adjustable circulation of air by convection. In fact, if cold air can descend (the cold source is in the upper compartment) through the openings 13, an equivalent quantity of heated air cannot go up towards the cold compartment. Admittedly there is at the front of the device a thin slot (6 mm maximum) between the edge of the partition wall 12 of the counter door of the refrigerator, but this slot is much too small compared to the dimensions of the slots 13 to ensure circulation by convection.

Enfin le brevet américain US-A-2 493 488 décrit des étagères destinées à séparer d'un compartiment B refroidi par son évaporateur 15, un compartiment E où sont fabriqués les glaçons et qui comporte sa propre source froide: évaporateur auxiliaire 17. Des ouvertures 20 sont disposées de part et d'autre des étagères 16; leur seule fonction décrite (et possible) est de laisser descendre vers le compartiment inférieur E de la vapeur d'eau. Aucun échange thermique n'est prévu entre les deux compartiments qui ont chacun leur source froide.Finally, US patent US-A-2 493 488 describes shelves intended to separate from a compartment B cooled by its evaporator 15, a compartment E where ice cubes are made and which has its own cold source: auxiliary evaporator 17. Openings 20 are arranged on either side of the shelves 16; their only function described (and possible) is to allow water vapor to descend to the lower compartment E. No heat exchange is planned between the two compartments which each have their cold source.

Ainsi les dispositifs de l'état de la technique n'utilisent pas au mieux la propriété physique qui fait que l'air froid descend tandis que l'air plus chaud remonte.Thus, the devices of the state of the art do not make the best use of the physical property which causes the cold air to descend while the warmer air rises.

L'invention par contre utilise cette propriété pour rendre plus efficace la circulation d'air grâce à un dispositif de cloisonnement réglable ayant, dans sa position ouverte, au moins une ouverture à l'arrière de la cuve où est située la source froide, pour la descente de l'air froid et au moins une ouverture à l'avant de la cuve pour la montée de l'air réchauffé, ces ouvertures ayant toujours pratiquement les mêmes dimensions à l'avant et à l'arrière et de quel que soit le réglage.The invention on the other hand uses this property to make air circulation more efficient thanks to an adjustable partitioning device having, in its open position, at least one opening at the rear of the tank where the cold source is located, to the descent of the cold air and at least one opening at the front of the tank for the rise of the heated air, these openings always having practically the same dimensions at the front and at the rear and whatever adjustment.

Un moyen pour modifier à volonté la circulation d'air dans ce ou ces compartiments inférieurs est de pouvoir obturer plus ou moins les passages de circulation de l'air réfrigéré (circulation par convexion), celui-ci descendant le long de la paroi arrière de la cuve du réfrigérateur puis remontant le long de la contre-porte, à l'avant du réfrigérateur.One way to modify the air circulation in this or these lower compartments at will is to be able to more or less block the circulation passages of the refrigerated air (circulation by convection), the latter descending along the rear wall of the tank of the refrigerator then going up along the storm door, at the front of the refrigerator.

Le dispositif de cloisonnement à volets mobiles suivant la présente invention permet de moduler la température de la partie inférieure de la cuve d'un réfrigérateur tout en conservant une température sensiblement constante dans la partie supérieure de cette cuve.The partitioning device with movable shutters according to the present invention makes it possible to modulate the temperature of the lower part of the tank of a refrigerator while maintaining a substantially constant temperature in the upper part of this tank.

Suivant l'invention, un dispositif de cloisonnement réglable à volets mobiles pour appareil de production de froid, destiné à séparer plus ou moins, des compartiments normalement réfrigérés, au moins un compartiment situé par rapport à la zone de production de froid, à la partie basse de l'appareil, ce compartiment pouvant ainsi être moins froid que les compartiments normalement réfrigérés et à une température réglable, est caractérisé en ce qu'il comporte un élément de cloisonnement fixe ayant des dimensions telles qu'il laisse, à l'arrière de l'appareil où est située la source froide, au moins une ouverture de réglage laissant descendre l'air froid qui y est produit et à l'avant de l'appareil, au moins une ouverture de réglage de dimensions équivalentes à celles de l'ouverture arrière permettant le retour de l'air réchauffé vers la partie supérieure de l'appareil où est produit le froid, et en ce qu'il comporte en outre au moins deux volets mobiles susceptibles de fermer plus ou moins respectivement les au moins deux ouvertures, ces au moins deux volets mobiles étant couplés mécaniquement par des moyens de couplage tels que le déplacement de l'un entraîne le déplacement de l'autre en sens inverse, de manière à simultanément ouvrir ou fermer les ouvertures de la même quantité.According to the invention, an adjustable partitioning device with movable flaps for cold production apparatus, intended to separate more or less, normally refrigerated compartments, at least one compartment located relative to the cold production zone, to the part bottom of the appliance, this compartment which can thus be less cold than the compartments normally refrigerated and at an adjustable temperature, is characterized in that it comprises a fixed partition element having dimensions such that it leaves, at the rear of the device where the cold source is located, at least one adjustment opening allowing the cold air produced therein to descend and, at the front of the device, at least one adjustment opening of dimensions equivalent to those of the rear opening allowing the return of the heated air to the upper part of the appliance where the cold is produced, and in that it also comprises at least two movable shutters capable of closing the at least more or less respectively two openings, these at least two movable flaps being mechanically coupled by coupling means such that the displacement of one causes the displacement of the other in the opposite direction, so as to simultaneously open or close the openings by the same amount.

L'invention sera mieux comprise et d'autres caractéristiques apparaîtront à l'aide de la description ci-après et des dessins qui l'accompagnent et sur lesquels:

  • - la figure 1 montre une vue partielle d'un réfrigérateur muni d'un dispositif de cloisonnement à volets mobiles suivant l'invention;
  • - les figures 2 et 3 représentent, en coupe transversale, des détails de la figure 1 correspondant respectivement à deux positions des volets mobiles;
  • - la figure 4 montre une variante de réalisation du dispositif de cloisonnement à volets mobiles suivant l'invention.
The invention will be better understood and other characteristics will appear from the following description and the accompanying drawings, in which:
  • - Figure 1 shows a partial view of a refrigerator fitted with a partitioning device with movable shutters according to the invention;
  • - Figures 2 and 3 show, in cross section, details of Figure 1 respectively corresponding to two positions of the movable flaps;
  • - Figure 4 shows an alternative embodiment of the partitioning device with movable shutters according to the invention.

La figure 1 montre une vue partielle d'un réfrigérateur équipé d'un dispositif de cloisonnement horizontal réglable à volets mobiles suivant l'invention.Figure 1 shows a partial view of a refrigerator equipped with an adjustable horizontal partitioning device with movable shutters according to the invention.

Dans l'exemple décrit ici, il s'agit d'un appareil de production de froid tu type réfrigérateur. Mais il pourrait tout aussi bien s'agir d'un congélateur. Il peut en effet, être utile d'avoir, à la partie basse d'un congélateur un (ou plusieurs) compartiment que l'on utilise, au choix, en congélateur comme le reste de l'appareil, ou en conservateur, c'est-à-dire à une température un peu supérieur à celle du reste de l'appareil.In the example described here, it is an appliance for producing refrigeration, such as a refrigerator. But it could just as easily be a freezer. It may indeed be useful to have, at the bottom of a freezer one (or more) compartment which is used, as desired, as a freezer like the rest of the appliance, or as a preservative, that is to say at a temperature slightly higher than that of the rest of the device.

Le dispositif de cloisonnement de l'invention comporte un premier élément 1 de cloisonnement horizontal fixe coopérant avec un second élément 2 de cloisonnement horizontal à volets mobiles 3, 4 permettant le réglage de la circulation d'air dans un (figures 2, 3) ou plusieurs (figure 1) compartiments C situés dans la partie inférieure de la cuve du réfrigérateur. Les figures 2 et 3 montrent les détails d'un dispositif de cloisonnement horizontal suivant l'invention.The partitioning device of the invention comprises a first element 1 of fixed horizontal partitioning cooperating with a second element 2 of horizontal partitioning with movable flaps 3, 4 allowing the adjustment of the air circulation in one (FIGS. 2, 3) or several (Figure 1) compartments C located in the lower part of the refrigerator tank. Figures 2 and 3 show the details of a horizontal partitioning device according to the invention.

De manière générale, l'élément de cloisonnement fixe 1 est formé d'un p!ateau horizontal fixé aux parois latérales de la cuve R du réfrigérateur et a des dimensions telles que ses bords postérieur 5 et antérieur 6 se trouvent en retrait de la paroi verticale 7 postérieure et de la contre-porte 8 de la cuve R. Ainsi cet élément de cloisonnement fixe 1 laisse, à l'arrière de la cuve, une ouverture 16 laissant descendre l'air froid produit par le réfrigérateur, dans sa partie supérieure où se trouve l'évaporateur (non représenté), et à l'avant une ouverture 17 permettant le retour vers la partie supérieure de l'appareil de l'air réchauffé.In general, the fixed partition element 1 is formed by a horizontal plate fixed to the side walls of the tank R of the refrigerator and has dimensions such that its rear 5 and front 6 edges are set back from the wall. vertical 7 posterior and against the door 8 of the tank R. Thus this fixed partition element 1 leaves, at the rear of the tank, an opening 16 letting down the cold air produced by the refrigerator, in its upper part where the evaporator is (not shown), and at the front an opening 17 allowing the return to the upper part of the device of the heated air.

Il est clair que l'invention couvre également une variante dans laquelle ces deux ouvertures pourraient être remplacées chacune par plusieurs ouvertures. Dans ce cas, le plateau constituant l'élément de cloisonnement fixe 1 se prolongerait vers l'avant et vers l'arrière du réfrigérateur et serait percé, dans les deux zones correspondant à ces ouvertures 16 et 17, de plusieurs ouvertures.It is clear that the invention also covers a variant in which these two openings could each be replaced by several openings. In this case, the plate constituting the fixed partition element 1 would extend towards the front and towards the rear of the refrigerator and would be pierced, in the two zones corresponding to these openings 16 and 17, with several openings.

Le point important pour le bon fonctionnement de la présente invention est qu'il existe au moins un passage pour l'air, d'une part à l'arrière 16 du réfrigérateur et d'autre part à l'avant 17, de manière que, lorsque le/les compartiments inférieurs doivent être aussi froid que le reste, l'air réfrigéré y circule convenablement.The important point for the proper functioning of the present invention is that there is at least one air passage, on the one hand at the rear 16 of the refrigerator and on the other hand at the front 17, so that , when the lower compartment (s) must be as cold as the rest, the refrigerated air circulates there properly.

Parallèlement au premier élément 1 et, avantageusement, sous cet élément, est monté un second élément 2 de cloisonnement à volets mobiles 3, 4.Parallel to the first element 1 and, advantageously, under this element, is mounted a second partition element 2 with movable shutters 3, 4.

Il serait possible, dans une autre variante de réalisation, de disposer ces deux volets mobiles audessus de l'élément fixe 1. Toutefois la construction de l'ensemble serait un peu plus compliquée puisqu'il faudrait alors venir masquer la partie centrale de ces deux volets mobiles par un contre-élément fixe.It would be possible, in another alternative embodiment, to have these two movable flaps above the fixed element 1. However, the construction of the assembly would be a little more complicated since it would then be necessary to hide the central part of these two movable shutters by a fixed counter-element.

Les deux volets mobiles 3 et 4 ont une forme générale en équerre, sont imbriqués et présentent respectivement sur leurs bords en vis-à-vis, situés dans la zone centrale du compartiment C, des parties dentées formant crémaillères 9, 10 destinées à coopérer avec une roue dentée 11 mobile autour d'un axe 12 fixé sur l'élément 1 fixe, sensiblement au centre de cet élément 1 et perpendiculairement à celui-ci.The two movable flaps 3 and 4 have a generally square shape, are nested and have respectively on their opposite edges, located in the central zone of compartment C, toothed parts forming racks 9, 10 intended to cooperate with a toothed wheel 11 movable about an axis 12 fixed on the fixed element 1, substantially at the center of this element 1 and perpendicular to it.

Les volets 3, 4 sont engagés respectivement dans des glissières 13, 14 latérales permettant un déplacement des volets mobiles 3 et 4 parallèlement à ces glissières 13, 14. Le volet mobile 4 est muni d'une tirette 15.The flaps 3, 4 are engaged respectively in lateral slides 13, 14 allowing movement of the mobile flaps 3 and 4 parallel to these slides 13, 14. The mobile flap 4 is provided with a pull tab 15.

Dans la position montrée en figure 2, les volets mobiles 3, 4 sont placés l'un contre l'autre, laissant circuler l'air réfrigéré vers le/les compartiments inférieurs par les ouvertures postérieure et antérieure 16, 17 ménagées entre les bords libres 5, 6 de l'élément 1 et de la paroi verticale 7 de la cuve R et de la contre-porte du réfrigérateur.In the position shown in Figure 2, the movable flaps 3, 4 are placed one against the other, letting the refrigerated air circulate towards the / the lower compartments by the rear and anterior openings 16, 17 formed between the free edges 5, 6 of the element 1 and of the vertical wall 7 of the tank R and of the counter-door of the refrigerator.

Si l'on désire diminuer la circulation d'air froid dans le compartiment C et obtenir ainsi une température plus élevée dans ce compartiment C que dans le reste de la cuve, on tire dans le sens de la flèche sur la tirette 15, entraînant un déplacement simultané (figure 3) du volet 3 vers l'arrière, c'est-à-dire vers la paroi verticale 7 postérieure du réfrigérateur R, et du volet 4 vers l'avant, c'est-à-dire vers la contre-porte 8, diminuant ainsi de façon désirée les ouvertures 16, 17 postérieure et antérieure de circulation d'air.If you want to reduce the circulation of cold air in compartment C and thus obtain a higher temperature in this compartment C than in the rest of the tank, pull in the direction of the arrow on the pull tab 15, causing a simultaneous movement (FIG. 3) of the flap 3 towards the rear, that is to say towards the vertical rear wall 7 of the refrigerator R, and of the flap 4 towards the front, that is to say towards the counter door 8, thereby decreasing the openings 16, 17 posterior and anterior of air circulation in a desired manner.

Dans une variante montrée en figure 4, une plaque 18 en matériau thermiquement isolant (du polystyrène expansé par exemple) est disposée entre les éléments 1 et 2. Cette plaque 18 peut être fixée sur l'élément 1 fixe, assurant une bonne isolation thermique entre le compartiment C et la partie supérieure de la cuve lorsque les volets 3 et 4 sont écartés l'un de l'autre. La plaque 18 a sensiblement les dimensions de l'élément 1.In a variant shown in Figure 4, a plate 18 of thermally insulating material (expanded polystyrene for example) is disposed between the elements 1 and 2. This plate 18 can be fixed on the fixed element 1, ensuring good thermal insulation between the compartment C and the upper part of the tank when the flaps 3 and 4 are separated from one another. The plate 18 has substantially the dimensions of the element 1.

Dans l'exemple représenté en figure 2, le réfrigérateur R est muni d'un dispositif de cloisonnement à volets mobiles 3, 4 mais il peut être avantageux d'inclure dans la cuve plusieurs compartiments comportant un dispositif de cloisonnement à volets mobiles suivant l'invention, permettant ainsi de réaliser dans la partie inférieure de la cuve des compartiments à des températures différentes (comprises par exemple entre +5° et +12°) et appropriées à la conservation de produits alimentaires divers.In the example shown in FIG. 2, the refrigerator R is provided with a partitioning device with movable shutters 3, 4 but it may be advantageous to include in the tank several compartments comprising a partitioning device with movable shutters according to the invention, thus making it possible to produce compartments at the lower part of the tank at different temperatures (for example between + 5 ° and + 12 °) and suitable for the conservation of various food products.
