Description

La présente invention a pour objet un humidificateur par vaporisation.The present invention relates to a spray humidifier.

Les humidificateurs sont utilisés notamment pour la régulation de l'hygrométrie de l'air ambiant que ce soit sur un lieu de travail ou dans un local servant au stockage de marchandises.Humidifiers are used in particular for regulating the humidity of the ambient air, whether at a workplace or in a room used for the storage of goods.

Ces humidificateurs sont pratiquement tous de conception identique et utilisent le même principe, à savoir qu'ils comportent un coffret en tôle pliée et plastique renfermant les divers moyens de commande électriques et à l'intérieur duquel est placée une cuve, ou cylindre de vapeur, remplie d'eau destinée à générer de la vapeur.These humidifiers are practically all of identical design and use the same principle, namely that they comprise a box of folded sheet metal and plastic containing the various electrical control means and inside which is placed a tank, or steam cylinder, filled with water to generate steam.

Cette eau, où sont plongées deux ou trois électrodes alimentées en courant alternatif, est portée à ébullition et transformée en vapeur, évacuée par une gaine débouchant au sommet de ladite cuve. Au fur et à mesure de la production de vapeur, pour conserver à l'eau ses propriétés initiales et éviter une trop grande concentration en sels minéraux conducteurs, on évacue une partie de cette eau et on la remplace.This water, in which two or three electrodes supplied with alternating current are immersed, is brought to a boil and transformed into steam, evacuated by a sheath opening at the top of said tank. As steam is produced, to keep the water's initial properties and avoid too high a concentration of conductive mineral salts, part of this water is removed and replaced.

Ce type d'humidificateur, décrit par exemple dans EP-A-0 453 385, présente de nombreux inconvénients, notamment en ce qui concerne l'évacuation de l'eau, celle-ci se faisant par la base de la cuve, où s'amasse le dépôt calcaire qui encrasse la vanne d'évacuation, ce qui est une source de panne.This type of humidifier, described for example in EP-A-0 453 385, has many disadvantages, in particular with regard to the evacuation of the water, this being done by the base of the tank, where s '' builds up the lime deposit which clogs the drain valve, which is a source of failure.

D'autre part les cuves doivent être régulièrement nettoyées, ce qui nécessite leur dépose, opération qui s'effectue au prix de nombreuses manipulations, notamment la déconnection des raccords d'arrivée et d'évacuation d'eau, qui comportent chacun à chaque extrémité un collier de serrage, la déconnection des électrodes, puis le nettoyage de ces différentes parties, enfin la reconnection de l'ensemble sans omettre le nettoyage ou le remplacement des différents filtres et joints d'étanchéité.On the other hand, the tanks must be regularly cleaned, which requires their removal, an operation which is carried out at the cost of numerous manipulations, in particular the disconnection of the water inlet and outlet fittings, which each have at each end. a clamp, disconnection of the electrodes, then cleaning of these different parts, finally reconnection of the whole without omitting the cleaning or replacement of the various filters and seals.

D'autre part encore, il est nécessaire de concevoir un coffret différent pour chaque humidificateur de capacité différente, et le montage de tels humidificateurs est relativement long.On the other hand, it is necessary to design a different cabinet for each humidifier of different capacity, and the assembly of such humidifiers is relatively long.

La présente invention permet de remédier à ces inconvénients en proposant un humidificateur par vaporisation très compact, ne comportant que très peu de raccords et connections, donc d'un montage et d'un entretien aisé, et en outre d'un coût de fabrication très réduit.The present invention makes it possible to remedy these drawbacks by proposing a very compact vaporizing humidifier, comprising only very few fittings and connections, therefore of easy assembly and maintenance, and furthermore a very low manufacturing cost. reduced.

L'humidificateur par vaporisation objet de la présente invention, défini dans la revendication 1, comporte un coffret, de forme générale parallélépipèdique, constitué d'une partie supérieure et d'une partie inférieure, entre lesquelles se fixe un profil en aluminium, réalisé par extrusion, incorporant dans sa structure différents canaux.The spray humidifier object of the present invention, defined in claim 1, comprises a box, of generally parallelepiped shape, consisting of an upper part and a lower part, between which an aluminum profile is fixed, produced by extrusion, incorporating different channels into its structure.

Les parties supérieure et inférieure, sont des boîtiers compartimentés et fermés par un couvercle, comportant divers moyens d'assemblage avec les canaux du profilé en aluminium, ainsi qu'avec une gaine d'évacuation de la vapeur, une électrovanne d'alimentation en eau, et les différentes connections électriques.The upper and lower parts are compartments compartmentalized and closed by a cover, comprising various means of assembly with the channels of the aluminum profile, as well as with a steam evacuation duct, a water supply solenoid valve, and the various electrical connections.

Le boîtier de la partie inférieure est identique à celui de la partie supérieure mais est disposé symétriquement.The housing of the lower part is identical to that of the upper part but is arranged symmetrically.

La cuve est constituée d'un récipient comportant à sa partie supérieure, des fiches mâles de connections, reliées chacune à une électrode intérieure, un conduit d'évacuation de la vapeur et un orifice d'alimentation en eau, et latéralement dans sa moitié inférieure une sortie des eaux résiduelles.The tank consists of a container comprising at its upper part, male connection plugs, each connected to an internal electrode, a steam evacuation duct and a water supply orifice, and laterally in its lower half. an outlet for residual water.

La mise en place de la cuve dans le coffret s'effectue rapidement et sans danger en un seul mouvement, les fiches mâles sont enfichées dans la boîte supérieure qui comporte des fiches femelles prévues à cet effet, le conduit d'évacuation est emmanché sur le puits auquel est connecté la gaine d'évacuation, l'orifice d'alimentation en eau est connecté au puits d'alimentation, enfin la sortie d'eau est connectée à une électro-vanne positionnée sur le profil en aluminium . Ainsi le manipulateur peut effectuer cette opération en un mouvement d'arrière en avant, puis de bas en haut, sans qu'il y ait de contact manuel avec une source d'électricité ou de chaleur, comme c'est le cas avec les humidificateurs actuels.The installation of the tank in the box is carried out quickly and without danger in a single movement, the male plugs are inserted in the upper box which includes female plugs provided for this purpose, the evacuation duct is fitted on the well to which the evacuation sheath is connected, the water supply orifice is connected to the supply well, finally the water outlet is connected to a solenoid valve positioned on the aluminum profile. Thus the manipulator can carry out this operation in a movement from back to front, then from bottom to top, without there being manual contact with a source of electricity or heat, as is the case with humidifiers current.

Le fait que la sortie d'eau soit placée latéralement et non à la base de la cuve permet d'éviter l'obturation par le calcaire de la vanne d'évacuation. Lorsque la cuve sera trop encrassée, elle pourra être jetée, ou remplacée par une autre.The fact that the water outlet is placed laterally and not at the base of the tank makes it possible to avoid blockage by the limestone of the drain valve. When the tank is too dirty, it can be thrown away, or replaced by another.

Dans le cas d'un humidificateur de capacité différente, il suffit de modifier la hauteur du profilé en aluminium, le couvercle et la base restant les mêmes, ce qui permet de réduire le stock à des boîtes hautes ou basses, et des profilés de longueurs différentes.In the case of a humidifier of different capacity, it suffices to modify the height of the aluminum profile, the cover and the base remaining the same, which makes it possible to reduce the stock to high or low boxes, and profiles of lengths different.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Si on se référe aux figures 1, 2 et 3 on peut voir qu'un humidificateur 1 selon la présente invention comporte d'une part une partie supérieure 10 comprenant un boîtier 3 surmonté d'un couvercle 2, d'autre part une partie inférieure 11 constituée d'un boîtier 6 identique au boîtier supérieur 3 mais positionné symétriquement, placé sur un socle 7, d'autre part un profilé 4 en aluminium s'encastrant entre les boîtiers 3 et 6, et d'autre part encore une cuve 3 positionnée dans le profilé 4 sous le boîtier supérieur 3If we refer to Figures 1, 2 and 3 we can see that a humidifier 1 according to the present invention comprises on the one hand an upper part 10 comprising a housing 3 surmounted by a cover 2, on the other hand a lower part 11 consisting of a housing 6 identical to the upper housing 3 but symmetrically positioned, placed on a base 7, on the other hand an aluminum profile 4 fitting between the housings 3 and 6, and on the other hand a tank 3 positioned in the profile 4 under the upper housing 3

Le couvercle 2 comporte un fond 22 sur le pourtour duquel lui sont solidarisées, au-dessus une paroi 20, et en dessous une paroi 21, cette dernière étant en retrait vers l'intérieur par rapport à la paroi 20, de manière à pouvoir s'emboîter sur le boîtier 3. Le fond 22 est percé d'un orifice 23 prolongé vers le bas par un puits 24.The cover 2 has a bottom 22 on the periphery of which are secured to it, above a wall 20, and below a wall 21, the latter being set back inwards relative to the wall 20, so as to be able to s 'fitting onto the housing 3. The bottom 22 is pierced with an orifice 23 extended downwards by a well 24.

Les boîtiers 3 et 6 comportent un fond 31, respectivement 61, sur le pourtour duquel est solidarisée une paroi 30, respectivement 60, dont le bord inférieur, respectivement supérieur, déborde le fond 31, respectivement 61, pour permettre leur fixation sur le profilé 4 en aluminium.The boxes 3 and 6 have a bottom 31, respectively 61, on the periphery of which is joined a wall 30, respectively 60, the lower edge, respectively upper, projects beyond the bottom 31, respectively 61, to allow their attachment to the aluminum profile 4.

Le boîtier 3 est compartimenté, tout comme le boîtier 6 mais les compartiments de l'un n'ont pas la même fonction que ceux de l'autre.The housing 3 is compartmentalized, just like the housing 6 but the compartments of one do not have the same function as those of the other.

Un compartiment 38 isolé du reste du boîtier 3 et situé à sa partie antérieure, contient la carte électronique 39 de commande de l'humidificateur 1, la façade 300 de la paroi 30 portant les différentes commandes, mise sous tension, mise en marche, régulation, vidange, etc..., de celui-ci.A compartment 38 isolated from the rest of the housing 3 and located at its front part, contains the electronic card 39 for controlling the humidifier 1, the front 300 of the wall 30 carrying the various commands, powering up, switching on, regulation. , emptying, etc ..., of it.

Un compartiment 36, situé à la partie postérieure du boîtier 3, est destiné à contenir l'électro-vanne 360 d'arrivée d'eau. Ce compartiment 36 contient lui-même deux compartiments 32 et 34 communiquant l'un avec l'autre, séparés par une paroi 320 de faible hauteur, et dans le fond desquels sont pratiqués des orifices , respectivement 33 et 35, prolongés vers le bas, en-dessous du fond 31, par des puits, respectivement 330 et 350.Dans le compartiment 36, le fond 31 est également percé d'un orifice 361 prolongé vers le bas par un puits 362, (voir figure 3) et d'un autre orifice 37 prolongé vers le haut d'un puits 370.A compartment 36, located at the rear part of the housing 3, is intended to contain the water inlet solenoid valve 360. This compartment 36 itself contains two compartments 32 and 34 communicating with each other, separated by a wall 320 of low height, and in the bottom of which are made holes, respectively 33 and 35, extended downwards, below the bottom 31, by wells, 330 and 350 respectively. In the compartment 36, the bottom 31 is also pierced with an orifice 361 extended downwards by a well 362, (see FIG. 3) and a another orifice 37 extended upwards from a well 370.

Le profilé 4 et aluminium, réalisé par extrusion, comporte deux parties, 46 et 47, de section en forme de L se faisant face, ménageant ainsi un espace 40 dans la partie antérieure de l'humidificateur 1, et un espace 43, de volume inférieur, à sa partie postérieure. Les parties 46 et 47 sont creuses, et à l'intérieur de chacune d'elles s'étend verticalement un canal, respectivement 41 et 42.Profile 4 and aluminum, produced by extrusion, has two parts, 46 and 47, of L-shaped section facing each other, thus providing a space 40 in the front part of the humidifier 1, and a space 43, of volume lower, at its posterior part. The parts 46 and 47 are hollow, and inside each of them extends vertically a channel, respectively 41 and 42.

Le profilé 4 comporte en outre deux rainures verticales 44, 45 disposées en regard sur la ligne de séparation des espaces 40 et 43, et pratiquées respectivement dans les parties 46 et 47. Ces deux rainures verticales 44, 45 sont destinées à recevoir une plaque de tôle 48 à laquelle est solidarisée une électro-vanne 49 prenant place dans l'espace 43, la plaque 48 pouvant coulisser verticalement dans les rainures verticales 44 et 45.The profile 4 further comprises two vertical grooves 44, 45 arranged opposite on the line dividing the spaces 40 and 43, and formed respectively in the parts 46 and 47. These two vertical grooves 44, 45 are intended to receive a plate sheet 48 to which is secured an electro-valve 49 taking place in space 43, the plate 48 being able to slide vertically in the vertical grooves 44 and 45.

L'assemblage du boîtier 3 sur le profilé 4 s'effectue de manière que la partie inférieure de la paroi 30 recouvre le bord supérieur dudit profilé, le puits 330 du compartiment 33 s'insérant dans le canal vertical 41, et le puits 362 du compartiment 36 s'insérant dans le canal 42.The assembly of the housing 3 on the profile 4 is carried out so that the lower part of the wall 30 covers the upper edge of said profile, the well 330 of the compartment 33 being inserted in the vertical channel 41, and the well 362 of the compartment 36 fitting into channel 42.

Le couvercle 2 est positionné sur le boîtier 3, le puits 370 du compartiment 36 s'insérant dans l'orifice 24.The cover 2 is positioned on the housing 3, the well 370 of the compartment 36 being inserted in the orifice 24.

Le boîtier 6 est assemblé à la base du profilé 4 de la même manière que le boîtier 3 à sa partie supérieure. On peut voir sur la figure 1 que le canal 41 débouche dans un puits 62, correspondant au puits 362 du compartiment 36 et débouchant dans le socle 7 au niveau d'un orifice 70 prolongé vers le bas par un puits 71 sur lequel est connectée une gaine d'extraction des eaux 72.The housing 6 is assembled at the base of the profile 4 in the same manner as the housing 3 at its upper part. It can be seen in FIG. 1 that the channel 41 opens into a well 62, corresponding to the well 362 of the compartment 36 and opens into the base 7 at the level of an orifice 70 extended downwards by a well 71 to which is connected a water extraction sheath 72.

Dans le boîtier 6 un puits 63, correspondant au puits 370 du boîtier 3, permet la récupération des eaux résiduelles provenant de fuites éventuelles, ce puits 63 débouchant dans une cuvette 73 du socle 7, l'ensemble formant un siphon.In the housing 6 a well 63, corresponding to the well 370 of the housing 3, allows the recovery of residual water from possible leaks, this well 63 opening into a bowl 73 of the base 7, the assembly forming a siphon.

La vanne 49 est reliée par un flexible 490 à un puits du boîtier 6, correspondant au puits 350 du boîtier 3.The valve 49 is connected by a hose 490 to a well of the housing 6, corresponding to the well 350 of the housing 3.

La cuve 5 est constituée de l'assemblage d'une demi-coque supérieure 50 et d'une demi-coque inférieure 51, solidarisées entre elles par leurs bords sur un joint 52.The tank 5 consists of the assembly of an upper half-shell 50 and a lower half-shell 51, joined together by their edges on a joint 52.

La demi-coque supérieure 50 comporte à sa face supérieure un orifice 53 prolongé vers l'extérieur par un puits 530, et un orifice 54 prolongé vers l'intérieur par un puits 540, et elle est traversée par deux fiches mâles 56, 57, sur lesquelles sont soudées respectivement des électrodes 58, 59 disposées à l'intérieur de la cuve 5.The upper half-shell 50 has on its upper face an orifice 53 extended outwards by a well 530, and an orifice 54 extended inwards by a well 540, and it is crossed by two male plugs 56, 57, on which are respectively welded electrodes 58, 59 arranged inside the tank 5.

Dans la demi-coque inférieure 51 est percé latéralement un orifice 55 prolongé vers l'extérieur par un puits 550.In the lower half-shell 51 is drilled laterally an orifice 55 extended outwards by a well 550.

La mise en place de la cuve 5 dans le reste de l'appareil s'effectue dans un premier temps en l'introduisant dans l'espace 40 du profilé 4 et en connectant le puits extérieur 550 de la semi-coque 51 à l'électro-vanne 49 portée par la plaque 48, l'herméticité de l'ensemble étant garantie par un joint d'étanchéité. Dans un deuxième on fait effectuer à la cuve 5 une translation du bas vers le haut, la plaque de tôle 48 coulissant dans les rainures verticales 44 et 45, et on introduit le puits extérieur 530 de la demi-coque 50 de la cuve 5 dans le puits 370 du compartiment 36 de la boîte 3, le puits inférieur 350 du compartiment 34 s'insérant dans l'orifice 54 de la demi-coque 50, et les fiches 56, 57 traversant le fond 31 de la boîte 3 au niveau du compartiment 38 par des orifices non représentés, puis traversant la carte électronique 39 par des orifices 390, 391, pour être connectées à des fiches femelles, non représentées, la cuve étant alors maintenue en position par des moyens de fixation également non représentés.The installation of the tank 5 in the rest of the apparatus is carried out firstly by introducing it into the space 40 of the profile 4 and by connecting the external well 550 of the semi-shell 51 to the solenoid valve 49 carried by the plate 48, the hermeticity of the assembly being guaranteed by a seal. In a second, the tank 5 is made to translate from the bottom up, the sheet metal plate 48 sliding in the vertical grooves 44 and 45, and the external well 530 of the half-shell 50 of the tank 5 is introduced into the well 370 of compartment 36 of the box 3, the lower well 350 of the compartment 34 fitting into the orifice 54 of the half-shell 50, and the plugs 56, 57 passing through the bottom 31 of the box 3 at the level of the compartment 38 by holes not shown, then passing through the electronic card 39 by holes 390, 391, to be connected to female plugs, not shown, the tank then being held in position by fixing means also not shown.

Le fonctionnement de l'humidificateur 1 selon l'invention est le suivant : l'eau est amenée dans le compartiment 34 par l'electro-vanne 360 placée dans le compartiment 36, et s'écoule jusque dans la cuve 5 par l'orifice 35 dont le puits 350 est connecté à l'orifice 54 de la cuve 5.The operation of the humidifier 1 according to the invention is as follows: the water is brought into compartment 34 by the electro-valve 360 placed in compartment 36, and flows into the tank 5 through the orifice 35, the well 350 of which is connected to the orifice 54 of the tank 5.

Dans le cas d'un trop-plein d'eau dans le compartiment 34, c'est-à-dire que le niveau d'eau dépasse la hauteur de la paroi 320, l'excédent d'eau s'écoule dans le compartiment 32 et s'évacue par l'orifice 33 dans le canal 41 du profil 4.In the case of an overflow of water in compartment 34, that is to say that the water level exceeds the height of the wall 320, the excess water flows into the compartment 32 and is discharged through the orifice 33 in the channel 41 of the profile 4.

Si par hasard l'orifice 33, ou le canal 41, s'obture, le trop-plein d'eau peut sortir des compartiments 32, 34, et se répandre dans le compartiment 36, d'où il est évacué dans le canal 42, par l'orifice 361.If by chance the orifice 33, or the channel 41, closes, the overflow of water can come out of the compartments 32, 34, and spread into the compartment 36, from where it is discharged into the channel 42 , through port 361.

Les électrodes 58, 59, baignant dans l'eau et alimentées en courant alternatif par les fiches mâles 56, 57, transforment cette eau en vapeur qui est évacuée par l'orifice 53, et amenée vers l'extérieur de l'humidificateur 1 par successivement le puits 530 et le puits 370, sur lequel est connectée une gaine non représentée. L'eau émanant d'éventuelles fuites est récupérée en divers points pour aboutir dans le compartiment 36 en vue d'être évacuée dans le canal 42 par l'orifice 361.The electrodes 58, 59, immersed in water and supplied with alternating current by the male plugs 56, 57, transform this water into vapor which is evacuated by the orifice 53, and brought to the outside of the humidifier 1 by successively the well 530 and the well 370, to which is connected a sheath not shown. The water emanating from possible leaks is recovered at various points to end up in the compartment 36 with a view to being discharged into the channel 42 through the orifice 361.

L'évacuation de l'eau, trop concentrée en sels minéraux, de la cuve 5 est réalisée par l'électro-vanne 49, qui puise dans la cuve par l'orifice 55.The evacuation of the water, too concentrated in mineral salts, from the tank 5 is carried out by the solenoid valve 49, which taps into the tank through the orifice 55.

Du fait de la position latérale de cet orifice 55, l'eau transitant par la vanne 49 n'est pas chargée de calcaire, qui reste dans le fond de la demi-coque 51, et la vanne 49 ne s'encrasse pas.Due to the lateral position of this orifice 55, the water passing through the valve 49 is not loaded with limescale, which remains in the bottom of the half-shell 51, and the valve 49 does not get dirty.

Les eaux à évacuer sont déversées dans le socle 7, soit par les canaux 41 et 42 du profilé, soit par le flexible 490, soit par le puits 63, puis s'écoulent par le puits 71 dans un raccord multidirectionnel 72.The water to be evacuated is poured into the base 7, either by the channels 41 and 42 of the profile, or by the hose 490, or by the well 63, then flow through the well 71 in a multidirectional connector 72.

D'autre part lorsque la cuve 5 est considérée comme trop encrassée de calcaire, il suffit de la déposer et de la remplacer par une autre, la cuve encrassée étant soit jetée soit réutilisée après nettoyage.On the other hand when the tank 5 is considered to be too dirty with lime, it suffices to deposit it and replace it with another, the dirty tank being either discarded or reused after cleaning.
