Description

DISPOSITIF DE VENTILATION MULTIFONCTION MOBILE MOBILE MULTIFUNCTION VENTILATION DEVICE
L'invention concerne un dispositif de ventilation multifonction mobile, permettant des traitements du flux d'air qu'il engendre. Elle a plus particulièrement pour objet, mais non exclusivement, la climatisation, la génération et la diffusion d'ions, la purification, la désodorisation ou encore l'humidification de l'air ambiant.The invention relates to a mobile multifunction ventilation device, allowing treatments of the air flow which it generates. It has more particularly, but not exclusively, the purpose of air conditioning, generation and diffusion of ions, purification, deodorization or humidification of the ambient air.
De façon générale, à l'heure actuelle, ces différentes fonctions sont assurées par des systèmes distincts, multipliant ainsi les installations. De surcroît, ce type de dispositifs requiert souvent une mise en place lourde et à poste fixe. De ce fait, l'équipement de plusieurs locaux implique l'usage d'une pluralité d'appareils.Generally speaking, these various functions are currently provided by separate systems, thus increasing the number of installations. In addition, this type of device often requires heavy installation and fixed position. Therefore, equipping several premises involves the use of a plurality of devices.
L'invention part également de la constatation qu'un ventilateur est d'un usage saisonnier et monofonctionnel qui présente des inconvénients pour le producteur comme pour l'acheteur. En effet, c'est un produit qui ne peut être vendu et/ou utilisé qu'une partie de l'année et qui, par conséquent, n'est rentable pour personne.The invention also starts from the observation that a fan is of seasonal and monofunctional use which has disadvantages for the producer as for the buyer. Indeed, it is a product which can only be sold and / or used part of the year and which, therefore, is not profitable for anyone.
Elle part donc de l'idée que l'on pourrait tirer partie de la structure et de la fonctionnalité d'un ventilateur pour des fonctions autres que celles qui lui sont communément imparties dans le but de rentabiliser le produit. Elle propose un ventilateur comprenant une structure-support, un bloc moteur porté par la structure, une turbine comportant des pales entraînées par le moteur protégé par un carter ajouré solidaire du corps du bloc moteur. Selon l'invention, ce dispositif de ventilation est caractérisé en ce qu'il comprend des moyens de fixation solidaires du corps du moteur et aptes à recevoir au moins un module amovible et interchangeable de traitement du flux d'air engendré par les pales, ce module étant situé dans le volume du carter positionné en amont de ladite turbine. Le fait que les susdits moyens de fixation sont conçus de manière à maintenir les susdits modules dans le volume du carter situé en amont des pales (par rapport au sens d'écoulement du flux d'air) présente l'avantage de faciliter les connexions entre les modules et le bloc moteur voire même la structure du ventilateur.It therefore starts from the idea that one could take advantage of the structure and functionality of a fan for functions other than those which are commonly assigned to it in order to make the product profitable. It offers a fan comprising a support structure, an engine block carried by the structure, a turbine comprising blades driven by the motor protected by an openwork casing secured to the body of the engine block. According to the invention, this ventilation device is characterized in that it comprises fixing means integral with the body of the engine and capable of receiving at least one removable and interchangeable module for processing the air flow generated by the blades, this module being located in the volume of the casing positioned upstream of said turbine. The fact that the above fixing means are designed so as to maintain the above modules in the volume of the casing situated upstream of the blades (relative to the direction of flow of the air flow) has the advantage of facilitating the connections between the modules and the engine block or even the structure of the fan.
Les susdits modules pourront être autonomes ou au contraire connectés à des dispositifs d'alimentation portés par la structure-support et/ou le corps du bloc moteur.The aforementioned modules may be autonomous or on the contrary connected to supply devices carried by the support structure and / or the body of the engine block.
L'ensemble bloc moteur/turbine pourra être fixé sur le support ou monté pivotant sur celui-ci autour d'un axe vertical, des moyens étant prévus pour entraîner ledit ensemble en rotation selon une course angulaire alternée.The engine / turbine unit assembly may be fixed on the support or pivotally mounted on the latter about a vertical axis, means being provided for driving said assembly in rotation according to an alternating angular travel.
Ces nouvelles fonctions, optionnelles de surcroît, se trouvent alors réunies sur un ventilateur de structure classique qui en plus d'être mobile va leur assurer une efficacité optimale notamment en jouant un rôle de diffuseur.These new functions, which are optional in addition, are then combined on a fan of conventional structure which, in addition to being mobile, will provide them with optimum efficiency, in particular by playing the role of a diffuser.
Par ailleurs, l'invention est conçue de façon à permettre un accès facile aux modules et à leurs moyens de fixation, que ce soit pour nettoyer ou modifier les options. A cet effet, le carter pourra être réalisé en deux coquilles dont l'une est fixée au bloc moteur et l'autre est amovible de manière à permettre l'accès aux pales et aux modules. De même, les pales pourront être démontables. Des modes d'exécution de l'invention seront décrits ci-après, à titre d'exemples non limitatifs, avec référence aux dessins annexés dans lesquels :Furthermore, the invention is designed to allow easy access to the modules and their fixing means, whether to clean or modify the options. To this end, the casing can be made of two shells, one of which is fixed to the engine block and the other is removable so as to allow access to the blades and to the modules. Similarly, the blades may be removable. Embodiments of the invention will be described below, by way of nonlimiting examples, with reference to the appended drawings in which:
La figure 1 représente une vue de face d'un ventilateur ;Figure 1 shows a front view of a fan;
La figure 2 représente une vue de côté éclatée du ventilateur ;Figure 2 shows an exploded side view of the fan;
La figure 3 représente une coupe axiale du nez du ventilateur ;Figure 3 shows an axial section of the fan nose;
La figure 4 représente une vue en perspective éclatée du nez du ventilateur.Figure 4 shows an exploded perspective view of the fan nose.
Dans l'exemple représenté sur ces figures, le ventilateur comporte trois parties principales : une structure- support 1, un bloc moteur 2 porté par la structure et une turbine 3 solidaire du bloc comprenant des pales et des modules de traitement, le tout à l'intérieur d'un carter grillagé de forme lenticulaire composé de deux coquilles Ci, C2. La structure-support 1 comprend deux parties A et B où la partie A peut être qualifiée de socle à proprement parlé et la partie B de corps de la structure 1. Le socle A est formé par la superposition de deux blocs tronconiques 4, 5. Le sommet de cette partie A est surmonté d'un manchon tubulaire vertical 6 qui est évidé et s'enfonce de moitié dans le socle A. La partie B de la structure-support présente la forme d'une « serpe » ou d'un « point d'interrogation ». Dans sa partie basse, elle comprend un embout tubulaire vertical 7 qui s'emboîte dans le manchon tubulaire 6 du socle A permettant ainsi une rotation de la partie B par rapport au socle A de 360° dans les deux sens. A partir de l'embout, la partie B fait un angle d'environ 45° avant de s'arrondir en changeant de direction et revenir à la verticale de l'embout après une partie horizontale.In the example shown in these figures, the fan has three main parts: a support structure 1, a motor unit 2 carried by the structure and a turbine 3 integral with the block comprising blades and treatment modules, all at inside of a lenticular-shaped mesh casing composed of two shells Ci, C 2 . The support structure 1 comprises two parts A and B where the part A can be qualified as a base itself and the part B of the body of the structure 1. The base A is formed by the superposition of two frustoconical blocks 4, 5. The top of this part A is surmounted by a vertical tubular sleeve 6 which is hollowed out and sinks in half into the base A. Part B of the support structure has the shape of a "billhook" or of a " interrogation point ". In its lower part, it comprises a vertical tubular end piece 7 which fits into the tubular sleeve 6 of the base A thus allowing rotation of the part B relative to the base A of 360 ° in both directions. From the tip, part B makes an angle of about 45 ° before rounding off by changing direction and returning to the vertical of the tip after a horizontal part.
Dans le tiers supérieur de la partie B de la structure-support 1 est située une réserve d'eau 8 munie dans sa partie supérieure droite d'un tube souple 9 contenant des fibres textiles destinées à conduire l'eau par capillarité. Ce tube aboutit à un module évaporateur situé dans la partie basse de la turbine 3 du ventilateur, entre la coquille C] et les pales 10, de façon à ce que l'entrée et la sortie du tube soit à peu près au même niveau pour permettre une meilleure diffusion de l'eau par capillarité. Pour remplir cette réserve, une ouverture, fermée par un bouchon 11 perforé pour permettre une prise d'air, a été prévue ; elle est située sur la partie supérieure horizontale de la partie B et est reliée par un tube 12 à la réserve d'eau 8. La purge de la réserve d'eau peut être éventuellement assurée par un tube 13 connecté dans le bas de la réserve et refermé par un bouchon ou un robinet débouchant à l'extérieur.In the upper third of part B of the support structure 1 is located a water reserve 8 provided in its upper right part with a flexible tube 9 containing textile fibers intended to conduct water by capillarity. This tube leads to an evaporator module located in the lower part of the fan's turbine 3, between the shell C] and the blades 10, so that the inlet and outlet of the tube are approximately at the same level to allow a better diffusion of water by capillarity. To fill this reserve, an opening, closed by a perforated plug 11 to allow an air intake, has been provided; it is located on the horizontal upper part of part B and is connected by a tube 12 to the water reserve 8. The draining of the water reserve can possibly be ensured by a tube 13 connected at the bottom of the reserve and closed by a plug or a tap opening to the outside.
Dans cet exemple, le bloc moteur 2 de forme tubulaire est articulé sur l'extrémité supérieure de la partie B de la structure-support 1 autour d'un axe horizontal 14 de manière à pouvoir être réglé en orientation et un axe vertical 15 pour l'oscillation. Le premier réglage est assuré au moyen d'une vis 16 qui vient se visser dans un perçage taraudé prévu dans la partie supérieure de la pièce B et qui vient en butée sur une pièce solidaire du bloc moteur 2. Le second réglage, à savoir l'oscillation du ventilateur, est effectué à l'aide d'un bouton 17 placé sur le dessus du bloc moteur 2 qui agit sur un mécanisme d'entraînement.In this example, the engine block 2 of tubular shape is articulated on the upper end of part B of the support structure 1 around a horizontal axis 14 so that it can be adjusted in orientation and a vertical axis 15 for the 'oscillation. The first adjustment is ensured by means of a screw 16 which is screwed into a threaded bore provided in the upper part of the part B and which abuts on a part integral with the engine block 2. The second adjustment, namely the oscillation of the fan is carried out using a button 17 placed on top of the engine block 2 which acts on a drive mechanism.
L'alimentation en énergie électrique du bloc moteur ainsi que des modules utilisant de l'énergie électrique est obtenue au moyen d'un circuit d'alimentation dont les organes de commande, soit un boîtier 18 pour la vitesse de ventilation et un interrupteur 19 pour un ioniseur, sont situés dans la partie supérieure horizontale de la pièce B. Ces circuits d'alimentation sont raccordés à une circuiterie portée par le bloc moteur 2 grâce à des connecteurs 20 prévus sous le bloc moteur. On notera que les organes de commande sont protégés par un capot de protection 21 articulé sur la partie supérieure de la pièce B. Le circuit d'alimentation peut être relié à un courant alternatif au moyen d'un câble 22 terminé par une prise électrique qui part du boîtier et ressort dans le bas de la partie B. Tels que représentés sur les figures 3 et 4, le ventilateur comprend le bloc moteur 2 et la turbine 3 solidaire du bloc moteur qui entraîne les pales 10 de la turbine 3. Les pales 10 sont contenues dans le carter grillagé comportant deux coquilles, l'une, Ci, étant solidaire du bloc moteur et l'autre, C2, s 'attachant à la première au moyen d'anneaux d'assemblage 23 et de points d'ancrage 24 pour lesdits anneaux situés sur les bordures périphériques de ces coquilles. Par ailleurs, les deux coquilles sont montées pivotantes l'une par rapport à l'autre, autour d'une vis 25 axée parallèlement à l'axe du moteur. Cette vis s'engage dans un orifice 26 prévu dans la bordure de la coquille Ci pour venir se visser dans une pièce de liaison 27 solidaire de la bordure de la coquille C2 avant d'être maintenue par un écrou 28. Ce système vis-écrou pourrait être éventuellement remplacé par un système à goupille.The supply of electrical energy to the engine block and to the modules using electrical energy is obtained by means of a supply circuit including the control members, ie a housing 18 for the ventilation speed and a switch 19 for an ionizer, are located in the horizontal upper part of part B. These supply circuits are connected to circuitry carried by the engine block 2 by means of connectors 20 provided under the engine block. It will be noted that the control members are protected by a protective cover 21 articulated on the upper part of the part B. The supply circuit can be connected to an alternating current by means of a cable 22 terminated by an electrical outlet which part of the housing and spring at the bottom of part B. As shown in FIGS. 3 and 4, the fan comprises the engine block 2 and the turbine 3 integral with the engine block which drives the blades 10 of the turbine 3. The blades 10 are contained in the mesh casing comprising two shells, the one, Ci, being integral with the engine block and the other, C 2 , attaching to the first by means of assembly rings 23 and anchor points 24 for said rings located on the peripheral edges of these shells . Furthermore, the two shells are pivotally mounted relative to one another, around a screw 25 which is parallel to the axis of the motor. This screw engages in an orifice 26 provided in the edge of the shell Ci to be screwed into a connecting piece 27 secured to the edge of the shell C 2 before being held by a nut 28. This screw system nut could possibly be replaced by a pin system.
Le bloc moteur contient un moteur et un générateur électrique 29 servant à l'alimentation d'un ioniseur 30 au moyen d'un câble 31.The engine block contains a motor and an electric generator 29 serving to supply an ionizer 30 by means of a cable 31.
La face avant du bloc moteur consiste en une platine 32 circulaire munie d'un perçage central par lequel passe l'arbre 33 d'entraînement du moteur. Cette platine 32 comprend en outre des perçages taraudés 34 (ici trois perçages) dans lesquels viennent se visser les vis de fixation 35 de la coquille Ci. A cet effet, cette coquille comporte une pièce de fixation coaxiale 36 en forme de disque, munie d'un perçage central 37 pour le passage de l'arbre 33 ainsi que trois perçages lisses 38 pour les vis de fixation 35. Le positionnement angulaire de la coquille est assuré par une protubérance 39 qui s'étend radialement en saillie à partir de la bordure du disque. Cette protubérance 39 s'engage dans une cavité de forme complémentaire prévue dans la platine 32.The front face of the engine block consists of a circular plate 32 provided with a central bore through which the motor drive shaft 33 passes. This plate 32 further comprises threaded holes 34 (here three holes) into which are screwed the fixing screws 35 of the shell Ci. For this purpose, this shell comprises a coaxial fixing part 36 in the form of a disc, provided with 'a central hole 37 for the passage of the shaft 33 as well as three smooth holes 38 for the fixing screws 35.

Elle comporte donc trois perçages lisses pour le passage des vis 35 ainsi qu'un perçage central coaxial 43 pour le passage de l'arbre 33 du moteur.The modules can be dismantled securely by means of a disc-shaped fixing piece 40 provided with a coaxial central bore, which is fixed coaxially on the fixing piece 36 by screwing a nut 41 onto a threaded tubular sleeve. integral with said fixing piece 36. It comprises therefore three smooth bores for the passage of the screws 35 as well as a coaxial central bore 43 for the passage of the shaft 33 of the motor.
Avantageusement la platine 32 et les deux pièces de fixation 36 et 40 pourront en outre comprendre trois perçages coaxiaux respectifs 44, 45, 46 pour le passage du ou des câbles d'alimentation 31 des modules tels que l'ionisateur 30.Advantageously, the plate 32 and the two fixing parts 36 and 40 may also include three respective coaxial bores 44, 45, 46 for the passage of the power cable or cables 31 of the modules such as the ionizer 30.
Par ailleurs, la pièce de fixation 40 comprend trois tiges filetées 47 qui s'étendent axialement à 120° l'une de l'autre et qui servent de support et de fixation par vissage des modules grâce à des écrous à ailettes 48.Furthermore, the fixing piece 40 comprises three threaded rods 47 which extend axially at 120 ° from one another and which serve as support and fixing by screwing the modules by means of wing nuts 48.
Le premier module mis en place à l'aide des tiges filetées 47 est un filtre 49, par exemple anti-graisse. Ce filtre se présente sous la forme d'un disque percé d'ouïes 50 d'aspiration d'air en forme d'amande réparties sur sa surface. Il est muni d'un perçage central lisse 51 pour l'arbre 33, de trois perçages lisses 52 pour les tiges 47 et d'une encoche 53 au bord du perçage central 51 pour le câble d'alimentation 31 du ioniseur 30. Un second filtre 54, anti-odeur en carbone actif, conçu sur le même modèle que le premier est placé de la même façon.The first module installed using the threaded rods 47 is a filter 49, for example anti-grease. This filter is in the form of a disc pierced with gills 50 of almond-shaped air suction distributed over its surface. It is provided with a smooth central bore 51 for the shaft 33, three smooth holes 52 for the rods 47 and a notch 53 at the edge of the central bore 51 for the power cable 31 of the ionizer 30. A second filter 54, anti-odor in active carbon, designed on the same model as the first is placed in the same way.
Le diffuseur d'ions 30 est inséré à la suite. Il comprend une pièce de fixation centrale 55 en forme de disque d'où partent six tiges ionisantes 56 terminées chacune par une boule isolante 57. Cette pièce 55 comporte trois perçages lisses 58 pour le passage des tiges 47 ainsi qu'un perçage central coaxial 59 pour le passage de l'arbre 33 du moteur. De plus, cette pièce 55 possède une cosse de contact 60 pour connecter le câble d'alimentation 31.The ion diffuser 30 is inserted below. It includes a central fastening part 55 in the form of a disc from which six ionizing rods 56 leave each terminated by an insulating ball 57. This part 55 comprises three smooth holes 58 for the passage of the rods 47 as well as a coaxial central bore 59 for the passage of the shaft 33 of the engine. In addition, this part 55 has a contact lug 60 for connecting the power cable 31.
La fixation de ces modules est alors complétée par les écrous à ailettes 48 qui sont vissés sur les tiges filetées 47 et l'écrou 41. Le montage est parfait à l'aide d'un joint périphérique 61 qui vient créer une certaine étanchéité entre le bord extérieur des filtres et la coquille Ci pour un usage optimal de ces derniers.The fixing of these modules is then completed by the wing nuts 48 which are screwed onto the threaded rods 47 and the nut 41. The mounting is perfect using a peripheral seal 61 which creates a certain seal between the outer edge of the filters and the shell Ci for optimal use of the latter.
Comme précédemment mentionné pour pouvoir effectuer la mise en place et la fixation des modules, les pales 10 du ventilateur doivent pouvoir être facilement démontées de l'arbre d'entraînement 33. A cet effet, les pales 10, ici au nombre de trois, sont fixées à un noyau central 62 muni d'un perçage lisse coaxial par lequel peut s'engager l'arbre 33 d'entraînement du moteur. Sur l'arbre 33 peut venir se visser un écrou de blocage 63 servant à serrer le noyau central 62 contre une entretoise 64 solidaire de l'arbre d'entraînement 33.As previously mentioned, in order to be able to install and fix the modules, the blades 10 of the fan must be able to be easily removed from the drive shaft 33. For this purpose, the blades 10, here three in number, are fixed to a central core 62 provided with a smooth coaxial bore through which the motor drive shaft 33 can engage. On the shaft 33 can be screwed a locking nut 63 used to tighten the central core 62 against a spacer 64 integral with the drive shaft 33.
Une fois ce montage achevé, le volume est clos par la mise en place de la coquille postérieure C2 du carter qui porte sur ses bords extérieurs les points d'ancrage 24 des anneaux 23 et du système permettant le pivotement des coquilles l'une par rapport à l'autre.Once this assembly is completed, the volume is closed by the installation of the rear shell C 2 of the casing which carries on its outer edges the anchoring points 24 of the rings 23 and of the system allowing the shells to pivot one by compared to each other.
Des modules se trouvent également situés sur la turbine, au niveau de la bordure périphérique de la coquille, c'est le cas d'un module de diffuseur de parfum d'ambiance consistant en des cartouches 65 contenant des fibres textiles qui sont destinées à être insérées dans des emplacements 66 prévus à cet effet sur la bordure de la coquille Ci.Modules are also located on the turbine, at the peripheral edge of the shell, this is the case of a room fragrance diffuser module consisting of cartridges 65 containing textile fibers which are intended to be inserted into locations 66 provided for this purpose on the edge of the shell Ci.
Des éléments de décoration peuvent être prévus tels que des tubes 67 de couleur en silicone emboîtés sur l'arrête de la bordure périphérique de la coquille Ci.Decorative elements can be provided such as tubes 67 of silicone color fitted onto the edge of the peripheral edge of the shell Ci.
L'invention ne se limite pas aux exemples précédemment décrits.
