Abstract

The moisture absorber consists of a container (12) to receive the extracted liquid (14), and a charge of a hygroscopic product (32) in a compartment (30) which has at least one wall (34a, 34b) which is permeable to air and moisture. The compartment (30) is located inside a support (22) which is fitted over the top of the container, has a mesh side wall (24) and is open towards the top of the container. The compartment is suspended from the upper wall (28) of the support, where it is held in place by retaining elements (40, 29a). The dimensions of the compartment's top (38) are greater than those of the upper wall's aperture, which has a recessed rim (40) to receive it.

Description

La présente invention concerne un dispositif d'absorption d'humidité comprenant un bac de récupération de liquide, une charge de produit hygroscopique et des moyens de support de cette charge au-dessus du bac.The present invention relates to a moisture absorption device comprising a liquid recovery tank, a load of hygroscopic product and means for supporting this load above the tank.

On connaît des dispositifs de ce type pour lesquels les moyens de support comprennent une simple grille ou analogue que l'on dispose en travers de l'ouverture de la face supérieure du bac et sur laquelle on place la charge de matière hygroscopique conditionnée dans une gaine ou dans un tissu perméable à l'air humide et à l'eau.Devices of this type are known for which the support means comprise a simple grid or the like which is placed across the opening in the upper face of the tank and on which the charge of conditioned hygroscopic material is placed in a sheath or in a fabric permeable to humid air and water.

La matière hygroscopique est une matière apte à absorber l'humidité de l'air et à la transformer en saumure. Cette matière, qui se présente généralement sous forme de granulés, contient la plupart du temps une substance active du type chlorure de calcium, éventuellement mélangée à une autre substance. La matière active est une substance irritante, dont le contact avec la peau et les yeux doit être évité. De plus, il faut éviter d'en respirer les poussières.Hygroscopic material is a material capable of absorbing moisture from the air and transforming it into brine. This material, which is generally in the form of granules, contains most of the time an active substance of the calcium chloride type, possibly mixed with another substance. The active ingredient is an irritant, the contact of which with the skin and the eyes must be avoided. In addition, avoid breathing the dust.

Dans une première catégorie de dispositifs connus, la matière hygroscopique conditionnée dans sa gaine perméable est, avant son utilisation, emballée dans un sac étanche. Pour l'utiliser, il faut donc ouvrir le sac étanche et directement manipuler la gaine pour la mettre en place sur la grille. Du fait du caractère irritant rappelé ci-dessus, la nécessité de manipuler directement la gaine est un inconvénient notable étant entendu que, la gaine étant perméable, un contact avec la gaine contenant la matière hygroscopique entraîne inévitablement un contact avec cette matière elle-même.In a first category of known devices, the hygroscopic material packaged in its permeable sheath is, before its use, packed in a sealed bag. To use it, you must open the waterproof bag and directly manipulate the sheath to place it on the grid. Due to the irritant nature mentioned above, the need to directly handle the sheath is a notable drawback, it being understood that, the sheath being permeable, contact with the sheath containing the hygroscopic material inevitably leads to contact with this material itself.

On peut dans certains cas disposer au-dessus de la grille supportant la charge hygroscopique un couvercle muni de perforations de circulation d'air. Cette disposition permet d'éviter un contact intempestif avec la matière hygroscopique en condition d'utilisation. La sécurité n'est toutefois pas complète puisque chaque manipulation, soit pour vider le bac, soit pour remplacer une charge épuisée par une nouvelle charge, est l'occasion d'un contact avec la matière hygroscopique.In some cases, a cover provided with air circulation perforations can be placed above the grid supporting the hygroscopic load. This arrangement makes it possible to avoid inadvertent contact with the hygroscopic material under conditions of use. Security is not complete, however, since each manipulation, either to empty the tank or to replace a used charge with a new charge, is the occasion for contact with the hygroscopic material.

Dans une deuxième catégorie de dispositifs connus, la matière hygroscopique est initialement contenue dans un emballage qu'il faut complètement ouvrir avant d'en transvaser le contenu dans une boîte munie de perforations de circulation d'air. On ferme ensuite cette boîte à l'aide d'une paroi amovible et on la place au-dessus du bac. Cette manipulation, qui implique un contact direct avec les granulés de matière hygroscopique, est dangereuse.In a second category of known devices, the hygroscopic material is initially contained in a package which must be completely opened before transferring the content into a box provided with air circulation perforations. Then close this box with a removable wall and place it above the tray. This manipulation, which involves direct contact with the granules of hygroscopic material, is dangerous.

La demande de brevet EP-A-0 116 239 montre un dispositif de ce type, dans lequel la charge hygroscopique est contenue dans une nacelle munie d'un rebord que l'on pose sur le rebord du bac pour suspendre la nacelle à l'intérieur de ce dernier. Un couvercle ajouré permettant le passage de l'air est ensuite posé sur la nacelle.Patent application EP-A-0 116 239 shows a device of this type, in which the hygroscopic load is contained in a nacelle provided with a rim which is placed on the rim of the tank to suspend the nacelle from the inside the latter. A perforated cover allowing the passage of air is then placed on the nacelle.

Ce couvercle peut être enlevé très facilement, de sorte que même un enfant peut avoir directement accès à la charge hygroscopique. De plus, il faut enlever le couvercle puis la nacelle lorsque l'on souhaite vider le bac, ce qui implique presque inévitablement un contact avec la matière hygroscopique.This cover can be removed very easily, so that even a child can have direct access to the hygroscopic load. In addition, you must remove the cover and then the basket when you want to empty the tank, which almost inevitably involves contact with the hygroscopic material.

La demande de brevet GB-A-2 067 428 montre un autre dispositif dans lequel la charge hygroscopique est placée sur une grille qui repose en travers de l'ouverture du bac, un couvercle ajouré supporté par le rebord du bac étant ensuite placé au-dessus de cette charge. Ce dispositif présente les mêmes inconvénients que le précédent.Patent application GB-A-2 067 428 shows another device in which the hygroscopic load is placed on a grid which rests across the opening of the tank, a perforated cover supported by the edge of the tank being then placed above this charge. This device has the same drawbacks as the previous one.

La présente invention s'applique à un dispositif d'absorption d'humidité comprenant un bac de récupération de liquide ayant une paroi latérale, une paroi de fond et une face supérieure ouverte, ainsi qu'une charge de produit hygroscopique ayant au moins une paroi perméable à l'air humide et à l'eau, le dispositif comprenant, en outre, des moyens de support de la nacelle au-dessus du bac.The present invention applies to a moisture absorption device comprising a liquid recovery tank having a side wall, a bottom wall and an open upper face, as well as a charge of hygroscopic product having at least one wall. permeable to humid air and water, the device further comprising means for supporting the nacelle above the tank.

L'invention se propose de remédier aux inconvénients précités en fournissant un dispositif du type défini ci-dessus qui permette de simplifier la mise en place ou le remplacement de la charge de matière hygroscopique et d'éviter, tant à l'occasion de ces manipulations que lors du vidage du bac, tout contact, direct ou indirect, avec cette matière.The invention proposes to remedy the aforementioned drawbacks by providing a device of the type defined above which makes it possible to simplify the placement or replacement of the charge of hygroscopic material and to avoid, both during these manipulations. that when emptying the tank, any contact, direct or indirect, with this material.

Ce but est atteint grâce au fait que les moyens de support comprennent un élément ajouré de support susceptible d'être placé au-dessus du bac, ledit élément de support ayant une paroi latérale ajourée, une face inférieure ouverte apte à se trouver en regard de la face supérieure du bac lorsque l'élément de support est placé au-dessus de ce dernier et une face supérieure ouverte, que la nacelle présente des dimensions adaptées à permettre son introduction dans l'élément ajouré du support par la face supérieure ouverte de ce dernier, que ladite nacelle est suspendue à un élément de paroi supérieure susceptible d'être placé en travers de l'ouverture de la face supérieure de l'élément ajouré de support, et que le dispositif comporte des moyens de retenue dudit élément de paroi supérieure dans ladite ouverture.This object is achieved thanks to the fact that the support means comprise an openwork support element capable of being placed above the tank, said support element having an openwork side wall, an open underside capable of being located opposite the upper face of the tank when the support element is placed above the latter and an open upper face, that the nacelle has dimensions adapted to allow its introduction into the perforated element of the support by the open upper face of this last, that said basket is suspended from a upper wall element capable of being placed across the opening of the upper face of the perforated support element, and that the device comprises means for retaining said upper wall element in said opening.

On voit que l'invention permet de mettre la charge de matière hygroscopique en place en manipulant la nacelle. A cette occasion, il est très facile de tenir la nacelle sans avoir aucun contact, direct ou indirect avec la matière hygroscopique. Il suffit par exemple de la tenir par son élément de paroi supérieure qui joue alors le rôle d'un organe de préhension. La mise en place de la nacelle est donc très simple puisqu'il suffit de la laisser glisser par l'ouverture de la face supérieure de l'élément ajouré de support jusqu'à ce que les moyens de retenue de l'élément de paroi supérieur de la nacelle jouent leur rôle.It can be seen that the invention makes it possible to place the charge of hygroscopic material in place by manipulating the nacelle. On this occasion, it is very easy to hold the basket without having any contact, direct or indirect with the hygroscopic material. It suffices for example to hold it by its upper wall element which then plays the role of a gripping member. The installation of the nacelle is therefore very simple since it suffices to let it slide through the opening of the upper face of the perforated support element until the retaining means of the upper wall element of the nacelle play their role.

Il faut également noter qu'une fois que la nacelle est mise en place dans l'élément ajouré de support, le dispositif forme un ensemble compact. La charge de matière hygroscopique est à la fois protégée par l'élément ajouré de support en lui-même et par la nacelle dans laquelle elle est contenue et qui est fermée vers le haut par l'élément de paroi supérieure, ce qui constitue une double sécurité permettant par exemple d'éviter qu'un enfant animé par une curiosité naturelle ne touche cette matière irritante.It should also be noted that once the nacelle is placed in the perforated support element, the device forms a compact assembly. The load of hygroscopic material is both protected by the perforated support element itself and by the nacelle in which it is contained and which is closed upwards by the upper wall element, which constitutes a double safety, for example to prevent a child animated by a natural curiosity from touching this irritating matter.

Pour vider le bac, il suffit de séparer du bac l'élément ajouré de support contenant la nacelle. A cette occasion, aucun contact avec la nacelle n'est nécessaire.To empty the tank, simply separate the openwork support element containing the basket from the tank. On this occasion, no contact with the nacelle is necessary.

L'invention sera bien comprise et ses avantages apparaîtront mieux à la lecture de la description détaillée qui suit, d'un mode de réalisation indiqué à titre d'exemple non limitatif. La limitation se réfère aux dessins annexés sur lesquels :

Les figures 1 et 2 montrent un dispositif d'absorption d'humidité 10 qui comprend un bac 12 de récupération de liquide 14. Le bac a une paroi latérale 16, une paroi de fond 18 et une face supérieure ouverte 20. Il présente sensiblement la forme d'un parallélépipède, sa paroi latérale étant toutefois très légèrement inclinée par rapport à la verticale, de sorte que le bac est évasé vers le haut. Sa face supérieure est totalement ouverte, de sorte que seul le bord supérieur 16a de la paroi latérale 16 subsiste sur cette face.Figures 1 and 2 show a moisture absorption device 10 which comprises a tank 12 for recovering liquid 14. The tank has a wall side 16, a bottom wall 18 and an open upper face 20. It has substantially the shape of a parallelepiped, its side wall being however very slightly inclined relative to the vertical, so that the tank is flared upward. Its upper face is completely open, so that only the upper edge 16a of the side wall 16 remains on this face.

Au-dessus du bac 12 est disposé un élément ajouré de support 22. Il comporte une paroi latérale ajourée 24, une face inférieure 26 ouverte apte à se trouver en regard de la face supérieure 20 du bac et de dimensions analogues à celles de cette dernière, ainsi qu'une face supérieure 28 qui, elle aussi, est ouverte. Ainsi, en condition d'utilisation, l'extrémité inférieure de l'élément de support repose sur l'extrémité supérieure du bac. Cet élément ajouré de support présente donc globalement la forme d'un parallélépipède dont la face inférieure est totalement ouverte et délimitée par le bord inférieur 24' de la paroi latérale et dont la face supérieure présente une ouverture 29, visible sur la figure 3, laissant subsister un rebord 28a. Les faces avant et arrière 24a et 24b sont toutefois légèrement inclinées par rapport à la verticale et vont en se rapprochant l'une de l'autre vers le haut.Above the tank 12 is arranged an openwork support element 22. It has an openwork side wall 24, an open lower face 26 capable of being located opposite the upper face 20 of the tank and of dimensions similar to those of the latter , as well as an upper face 28 which, too, is open. Thus, under conditions of use, the lower end of the support element rests on the upper end of the tank. This perforated support element therefore generally has the shape of a parallelepiped whose lower face is completely open and delimited by the lower edge 24 'of the side wall and whose upper face has an opening 29, visible in FIG. 3, leaving remain a rim 28a. The front and rear faces 24a and 24b are however slightly inclined with respect to the vertical and go towards each other upwards.

Dans l'exemple représenté, la paroi latérale 24 de l'élément de support 22 présente sur ses faces avant et arrière 24a et 24b, l'aspect d'une grille. En effet, des lumières verticales 23 entre lesquelles subsistent des barreaux 25 sont régulièrement pratiquées sur ces faces. En revanche, les côtés gauche et droit 24c et 24d de la paroi latérale 24 restent pleins. Il faut noter que d'autres formes de réalisation sont possibles, l'essentiel étant que les jours pratiqués dans la paroi latérale soient suffisamment importants et régulièrement répartis pour que la ventilation soit assurée.In the example shown, the side wall 24 of the support element 22 has on its front and rear faces 24a and 24b, the appearance of a grid. In fact, vertical lights 23 between which bars 25 remain are regularly formed on these faces. On the other hand, the left and right sides 24c and 24d of the side wall 24 remain full. It should be noted that other embodiments are possible, the main thing being that the days practiced in the side wall are sufficiently large and regularly distributed so that ventilation is ensured.

On voit dans l'arrachement partiel de la figure 1, ainsi que sur la coupe de la figure 2, qu'une nacelle 30 est disposée à l'intérieur de l'élément ajouré de support. Cette nacelle contient une charge de produit hygroscopique 32. Elle présente au moins une paroi perméable à l'air humide et à l'eau. Dans l'exemple représenté, c'est le cas des faces avant et arrière 34a et 34b de la paroi latérale 34 de la nacelle. En revanche, le fond 36, de même que les côtés de la paroi latérale, sont pleins.We see in the partial cutaway of Figure 1, as well as in the section of Figure 2, that a nacelle 30 is disposed inside the perforated support element. This nacelle contains a charge of hygroscopic product 32. It has at least one wall permeable to humid air and to water. In the example shown, this is the case of the front and rear faces 34a and 34b of the side wall 34 of the nacelle. On the other hand, the bottom 36, as well as the sides of the side wall, are full.

On notera que les faces avant et arrière 34a et 34b de la nacelle sont inclinées et vont en s'écartant l'une de l'autre vers le haut. Cette disposition permet à la saumure produite par la transformation de l'air humide sous l'action de la matière hygroscopique de s'écouler régulièrement et sans difficulté par les faces avant et arrière de la nacelle et, ceci, bien que le fond 36 de cette dernière soit plein.It will be noted that the front and rear faces 34a and 34b of the nacelle are inclined and move away from each other upwards. This arrangement allows the brine produced by the transformation of moist air under the action of hygroscopic material to flow regularly and without difficulty by the front and rear faces of the nacelle and, this, although the bottom 36 of the latter is full.

En condition d'utilisation, la nacelle est disposée à l'intérieur de l'élément ajouré de support 22. Plus précisément, elle présente des dimensions transversales tout au plus égales à la dimension de l'ouverture 29 de la face supérieure 28 de l'élément de support 22, ce qui permet son introduction à travers cette ouverture.Under conditions of use, the nacelle is disposed inside the perforated support element 22. More specifically, it has transverse dimensions at most equal to the dimension of the opening 29 of the upper face 28 of the 'support element 22, which allows its introduction through this opening.

La nacelle 30 est suspendue à un élément de paroi supérieure 38 qui forme une paroi pleine. Cette nacelle reste correctement positionnée dans l'élément de support 22 en condition d'utilisation grâce au fait que le dispositif comporte des moyens de retenue de l'élément de paroi supérieure 38 dans l'ouverture 29.The nacelle 30 is suspended from an upper wall element 38 which forms a solid wall. This nacelle remains correctly positioned in the support element 22 in conditions of use thanks to the fact that the device comprises means for retaining the upper wall element 38 in the opening 29.

Les moyens de retenue peuvent comprendre tout type d'agrafage, d'accrochage ou de clipsage. De préférence, l'élément de paroi supérieure 38 a des dimensions supérieures à celles de l'ouverture 29 et, par conséquent, supérieures aux dimensions transversales maximales de la nacelle 30. Ainsi, il présente un rebord 40 qui s'étend en surplomb par rapport à la paroi latérale 34 de la nacelle. Ce rebord est apte à reposer sur le bord 29a de l'ouverture 29.The retaining means may include any type of stapling, attachment or clipping. Preferably, the upper wall element 38 has dimensions greater than those of the opening 29 and, consequently, greater than the maximum transverse dimensions of the nacelle 30. Thus, it has a flange 40 which extends in overhang by relative to the side wall 34 of the nacelle. This rim is able to rest on the edge 29a of the opening 29.

Pour que l'élément de paroi supérieure 38 se trouve au même niveau que la paroi supérieure 28, le bord 29a de l'ouverture 29 présente un décrochement adapté à recevoir le rebord 40.So that the upper wall element 38 is at the same level as the upper wall 28, the edge 29a of the opening 29 has a recess adapted to receive the flange 40.

Grâce à ces dispositions, pour mettre en place la nacelle dans l'élément ajouré de support, il suffit de la tenir par l'élément de paroi supérieur, d'introduire son extrémité inférieure dans l'ouverture 29 et de la laisser glisser jusqu'à ce que le rebord 40 vienne de lui-même se caler sur le bord 29a. Sur leurs faces internes, les côtés gauche et droit 24c et 24d de la paroi latérale 24 de l'élément de support 22 présentent des nervures verticales 24' qui servent à guider la nacelle lors de son introduction et à la caler latéralement.Thanks to these arrangements, to set up the nacelle in the perforated support element, it suffices to hold it by the upper wall element, to introduce its lower end into the opening 29 and to let it slide until that the rim 40 comes to wedge itself on the edge 29a. On their internal faces, the left and right sides 24c and 24d of the side wall 24 of the support element 22 have vertical ribs 24 'which serve to guide the nacelle during its introduction and to wedge it laterally.

De manière avantageuse, les moyens de retenue permettent non seulement de retenir la nacelle vers le bas, mais également vers le haut. A cet effet, ils comportent une patte élastique 42, représentée en traits pointillés sur la figure 2 et mieux visible sur les vues de détail des figures 4 et 5. Cette patte 42 s'étend vers le bas à partir de l'élément de paroi supérieure 38 et présente au moins une portion 44 en saillie vers l'extérieur. L'élément de support ajouré, quant à lui, comporte un dégagement 46 ménagé sur sa face latérale et apte à recevoir la portion en saillie 44.Advantageously, the retaining means make it possible not only to hold the nacelle downwards, but also upwards. To this end, they comprise an elastic tab 42, shown in dotted lines in FIG. 2 and better visible in the detailed views of FIGS. 4 and 5. This tab 42 extends downwards from the wall element upper 38 and has at least one portion 44 projecting outwards. The perforated support element, meanwhile, has a clearance 46 formed on its lateral face and capable of receiving the projecting portion 44.

Dans l'exemple représenté, ce dégagement 46 est même constitué par un perçage local. Deux pattes élastiques 42 sont prévues, s'étendant chacune à partir d'un côté de l'élément de paroi supérieure 38. Les perçages 46 sont situés sur les côtés 24c et 24d de l'élément de support ajouré. On remarque sur la figure 5 que la face inférieure 44a de la zone en saillie 44 est conformée en rampe relevée vers l'extérieur, de manière à solliciter la patte 42 pour qu'elle s'écarte provisoirement du côté 24c ou 24d de l'élément de support ajouré lorsque l'on insère la nacelle dans ce dernier. Lorsque la nacelle a atteint sa position d'utilisation, la patte 42 revient dans sa situation naturelle du fait de son élasticité et la portion 44 en saillie est retenue dans le perçage 46.In the example shown, this clearance 46 is even constituted by a local drilling. Two elastic tabs 42 are provided, each extending from one side of the upper wall element 38. The holes 46 are located on the sides 24c and 24d of the perforated support element. Note in Figure 5 that the underside 44a of the projecting area 44 is shaped ramp raised towards the outside, so as to bias the tab 42 so that it temporarily departs from the side 24c or 24d of the perforated support element when the basket is inserted therein. When the nacelle has reached its position of use, the tab 42 returns to its natural situation due to its elasticity and the projecting portion 44 is retained in the bore 46.

Pour enlever la nacelle, par exemple lorsque la charge hygroscopique est usée et qu'il est nécessaire de mettre en place une nouvelle nacelle contenant une charge hygroscopique intacte, il suffit de solliciter manuellement les pattes 42 pour les ramener vers l'intérieur et faire sortir les portions en saillie des perçages 46.To remove the nacelle, for example when the hygroscopic load is worn out and it is necessary to install a new nacelle containing an intact hygroscopic load, it suffices to manually apply the tabs 42 to bring them inwards and bring out the protruding portions of the holes 46.

Dans l'exemple représenté, cette manipulation est facilitée par le fait que les pattes 42 s'étendent en prolongement de pattes de soutien 48, de dimensions plus importantes. C'est donc directement en appuyant sur les pattes 48 pour les ramener vers l'intérieur que l'on peut désengager la nacelle. Il faut noter que les pattes 48 ont une forme complémentaire de celles de découpes 50 pratiquées dans les côtés 24c et 24d de l'élément de support 22. Lorsque la nacelle est en position d'utilisation, l'extrémité inférieure des pattes 48 repose en butée sur le bord des découpes 50. Le fonctionnement du système serait identique si, à la place des perçages 46, étaient réalisées de simples zones en renfoncement sur la paroi intérieure des côtés 24c et 24d, aptes à recevoir les portions en saillie vers l'extérieur 44 des pattes 42.In the example shown, this manipulation is facilitated by the fact that the legs 42 extend in extension of support legs 48, of larger dimensions. It is therefore directly by pressing on the legs 48 to bring them inwards that the nacelle can be disengaged. It should be noted that the legs 48 have a shape complementary to those of cutouts 50 formed in the sides 24c and 24d of the support element 22. When the nacelle is in the use position, the lower end of the legs 48 rests in abutment on the edge of the cutouts 50. The operation of the system would be identical if, in place of the holes 46, were made simple recessed areas on the inner wall of the sides 24c and 24d, capable of receiving the portions projecting towards the outside 44 of legs 42.

Il est préférable que l'élément ajouré de support soit maintenu dans sa position d'utilisation sur le bac, afin d'éviter les risques de déplacement relatif de ces deux éléments. A cet effet, le bac 12 présente, au voisinage du bord de l'ouverture de sa face supérieure, constitué par l'extrémité supérieure 16a de la paroi latérale 16, des premiers moyens de maintien, tandis que l'élément ajouré de support 22 présente, au voisinage du bord de l'ouverture de sa face inférieure, constitué par l'extrémité inférieure 24' de sa paroi latérale 24, des deuxièmes moyens de maintien aptes à coopérer avec les premiers pour maintenir l'élément ajouré de support au-dessus du bac.It is preferable that the perforated support element is maintained in its position of use on the tank, in order to avoid the risks of relative displacement of these two elements. To this end, the container 12 has, in the vicinity of the edge of the opening of its upper face, constituted by the upper end 16a of the side wall 16, first holding means, while the perforated support element 22 present, near the edge of the opening of its lower face, constituted by the lower end 24 'of its side wall 24, of the second holding means capable of cooperating with the first to keep the perforated support element above the tank.

On peut réaliser ces premier et deuxième moyens de maintien sous la forme de tous types de systèmes d'accrochage ou de clipsage. Toutefois, il est avantageux qu'ils comprennent, d'une part, au moins une patte élastique 52 présentant une portion 54 en saillie vers l'extérieur et, d'autre part, au moins un dégagement ou un orifice 56 apte à recevoir cette portion en saillie. Dans l'exemple représenté, les pattes 52 équipent les extrémités supérieures des côtés de la paroi latérale 16 du bac, tandis que les orifices 56 sont ménagés sur les côtés de la paroi latérale 24 de l'élément ajouré de support. On pourrait également prévoir la disposition inverse, dans laquelle les pattes équiperaient l'élément ajouré de support tandis que les dégagements ou les orifices équiperaient le bac.These first and second holding means can be produced in the form of all types of attachment or clipping systems. However, it is advantageous that they comprise, on the one hand, at least one elastic tab 52 having a portion 54 projecting outwards and, on the other hand, at least one clearance or an orifice 56 capable of receiving this protruding portion. In the example shown, the tabs 52 equip the upper ends of the sides of the side wall 16 of the tank, while the orifices 56 are formed on the sides of the side wall 24 of the perforated support element. One could also provide the reverse arrangement, in which the tabs would equip the openwork support element while the clearances or the orifices would equip the tray.

Les extrémités des pattes pourraient être conformées en rampe pour inciter celles-ci à s'écarter élastiquement lorsque l'on dispose l'élément ajouré de support 22 sur le bac. Dans l'exemple représenté, ceci n'est pas nécessaire puisque les côtés 24c et 24d de l'élément 22 vont en s'évasant vers le bas.The ends of the legs could be shaped like a ramp to encourage them to move apart elastically when the perforated support element 22 is placed on the tank. In the example shown, this is not necessary since the sides 24c and 24d of the element 22 widen downwards.

Si l'on souhaite désolidariser l'élément 22 et le bac, il suffit d'appuyer sur les portions en saillie 54 des pattes pour les repousser élastiquement vers l'intérieur.If it is desired to separate the element 22 and the tank, it suffices to press on the protruding portions 54 of the tabs to push them elastically inwards.

Les pattes 42 et 48 précédemment évoquées peuvent être conformées comme les pattes 52.The legs 42 and 48 previously mentioned can be shaped like the legs 52.

Pour parfaire le calage de l'élément de support sur le bac, les extrémités supérieures du bac et inférieures de l'élément de support présentent des formes conjuguées. Plus précisément, l'extrémité supérieure 16a de la paroi latérale 16 du bac 12 présente une portion en renfoncement dans laquelle vient s'engager un prolongement de l'extrémité inférieure 24a de l'élément ajouré de support 22.To perfect the setting of the support element on the container, the upper ends of the container and lower ends of the support element have conjugate shapes. More specifically, the upper end 16a of the side wall 16 of the container 12 has a recessed portion in which an extension of the lower end 24a of the perforated support element 22 engages.

On décrit maintenant de manière plus précise la nacelle 30. Elle comporte une armature ayant au moins une portion de paroi ajourée. Dans l'exemple représenté, les faces avant et arrière de la nacelle sont ajourées. Plus précisément, l'armature 60 comporte un fond, qui constitue le fond 36 de la nacelle, deux côtés, et deux faces, respectivement avant et arrière, munies de barreaux 62 entre lesquels sont ménagées de larges fenêtres 64. L'armature 60 est avantageusement réalisée en une seule pièce en matière plastique moulée. Pour fermer les faces avant et arrière de la nacelle, et emprisonner ainsi la charge hygroscopique à l'intérieur de cette dernière, une gaine 66 perméable à l'air humide et à l'eau est fixée en travers des fenêtres 64. En fait, deux coupons de gaine sont respectivement fixés sur les faces avant et arrière de l'armature et recouvrent pratiquement la totalité de ces faces.The nacelle 30 will now be described more precisely. It comprises an armature having at least one portion of perforated wall. In the example shown, the front and rear faces of the nacelle are perforated. More specifically, the frame 60 has a bottom, which constitutes the bottom 36 of the nacelle, two sides, and two faces, respectively front and rear, provided with bars 62 between which are large windows 64. The frame 60 is advantageously made in a single piece of molded plastic. To close the front and rear faces of the nacelle, and thus trap the hygroscopic load inside the latter, a sheath 66 permeable to humid air and to water is fixed across windows 64. In fact, two sheath coupons are respectively fixed on the front and rear faces of the frame and cover practically all of these faces.

Pour le conditionnement avant utilisation, les gaines sont recouvertes par un film plastique étanche pelable, qu'il suffit de retirer juste avant la mise en place de la nacelle dans l'élément ajouré de support pour que la charge hygroscopique puisse jouer son rôle en étant mise au contact de l'air humide. L'élément de paroi supérieure 38 est fixé au reste de l'armature après la mise en place de la charge hygroscopique à l'intérieur de la nacelle. L'armature a en elle-même une relative rigidité, elle comporte une base qui constitue le fond 36 et des montants qui constituent les côtés, relativement rigides. Ainsi, la nacelle peut naturellement reposer sur sa base avant sa mise en place dans l'élément ajouré de support.For the packaging before use, the sheaths are covered by a peelable waterproof plastic film, which it suffices to remove just before placing the nacelle in the perforated support element so that the hygroscopic load can play its role by being brought into contact with humid air. The upper wall element 38 is fixed to the rest of the frame after the hygroscopic load has been placed inside the nacelle. The frame in itself has a relative rigidity, it comprises a base which constitutes the bottom 36 and uprights which constitute the sides, relatively rigid. Thus, the nacelle can naturally rest on its base before it is placed in the openwork support element.

Il faut également noter, que dans l'exemple représenté sur les figures, le fond de la nacelle dépasse légèrement vers le bas au-delà du bord inférieur 24a de la paroi latérale 24 de l'élément ajouré de support. Si l'on souhaite seulement vider le bac 12 sans changer la nacelle, il suffit d'enlever l'ensemble constitué par l'élément ajouré de support et par la nacelle en dégageant les pattes 52 et de poser cet ensemble qui repose naturellement sur la base de la nacelle. A aucun moment, il n'est nécessaire d'avoir un contact, direct ou indirect, avec la nacelle. Si la nacelle était plus courte, on pourrait agir de même en posant l'ensemble sur le bord inférieur 24' de la paroi latérale 24 de l'élément de support.It should also be noted that in the example shown in the figures, the bottom of the nacelle protrudes slightly downwards beyond the lower edge 24a of the side wall 24 of the perforated support element. If it is only desired to empty the tank 12 without changing the nacelle, it suffices to remove the assembly constituted by the perforated support element and by the nacelle by releasing the tabs 52 and to install this assembly which naturally rests on the base of the nacelle. At no time is it necessary to have direct or indirect contact with the nacelle. If the nacelle was shorter, the same could be done by placing the assembly on the lower edge 24 ′ of the side wall 24 of the support element.

Si l'on souhaite en revanche changer la nacelle, on peut l'enlever en actionnant les pattes 42 et 48. Lors des manipulations, il est très facile de ne toucher que l'élément de paroi supérieure ou que les côtés de la nacelle sans qu'aucun contact direct ou indirect, ne soit établi avec la charge de matière hygroscopique.If, on the other hand, you wish to change the basket, you can remove it by activating the tabs 42 and 48. During handling, it is very easy to touch only the upper wall element or only the sides of the basket without that no direct or indirect contact be established with the load of hygroscopic material.

Comme on le voit mieux sur la figure 1, le bac 12 comporte des moyens de visualisation du niveau de liquide à l'intérieur de ce bac. Ces moyens sont avantageusement constitués par une simple fenêtre 70 définie par une zone sensiblement transparente de la paroi latérale 16 du bac. La fenêtre 70 est avantageusement située sur la face avant de la paroi latérale 16.As best seen in Figure 1, the container 12 includes means for viewing the level of liquid inside this container. These means are advantageously constituted by a simple window 70 defined by a substantially transparent area of the side wall 16 of the tank. The window 70 is advantageously located on the front face of the side wall 16.

Le bac 12 peut être réalisé en matière plastique moulée, de même que l'élément ajouré de support et que l'élément de paroi supérieure 38.The container 12 can be made of molded plastic, as is the perforated support element and the upper wall element 38.

On notera que la ou les parois perméables de la nacelle est ou sont situées en regard de la ou des parois ajourées de l'élément de support 22. Pour faciliter la circulation de l'air, ces parois sont distantes (E) les unes des autres.It will be noted that the permeable wall or walls of the nacelle is or are situated opposite the perforated wall or walls of the support element 22. To facilitate the circulation of air, these walls are distant (E) from each other other.

L'élément de paroi supérieure 38 ou l'élément ajouré de support 22 peut être muni de moyens d'accrochage. Ainsi, les figures 1 et 2 montrent un crochet 80 (en traits mixtes interrompus), fixé (définitivement ou de façon démontable) à l'élément de paroi supérieure 38 et permettant l'accrochage du dispositif à un objet tel qu'une tringle, un piton ou analogue. La référence 81 de la figure 2 montre qu'un tel crochet peut, au choix, être plutôt réalisé, sur le rebord 28a de l'élément 22.The upper wall element 38 or the perforated support element 22 can be provided with hooking means. Thus, FIGS. 1 and 2 show a hook 80 (in broken dashed lines), fixed (definitively or detachably) to the upper wall element 38 and allowing the device to be hooked to an object such as a rod, a piton or the like. The reference 81 in FIG. 2 shows that such a hook can, as desired, rather be produced, on the rim 28a of the element 22.
