Description

VENTILATEUR EQUIPE D'UNE MANCHE A AIR FAN EQUIPPED WITH AN AIR HANDLE
La présente invention, située dans le domaine électroménager, propose un appareil domestique de ventilation.The present invention, located in the household appliance sector, provides a domestic ventilation appliance.
Certains ventilateurs domestiques se présentent comme un ensemble formé d'un moteur électrique, d'un rotor équipé de plusieurs pales, entraîné par le moteur, et d'une grille de protection, ledit ensemble étant monté rotatif sur un support fixe, par l'intermédiaire d'un axe généralement vertical. Le mouvement rotatif de l'ensemble autour de l'axe vertical est couramment de type alternatif ; il permet de répartir le flux d'air traversant le ventilateur suivant des directions variables .Some domestic fans are presented as an assembly formed by an electric motor, a rotor equipped with several blades, driven by the motor, and a protective grid, said assembly being rotatably mounted on a fixed support, by the through a generally vertical axis. The rotary movement of the assembly around the vertical axis is commonly of the alternative type; it distributes the air flow passing through the fan in variable directions.
De tels appareils sont de conception relativement complexe du fait du double mouvement de rotation du rotor, et en outre ne donnent pas entière satisfaction du point de vue de la répartition des flux d' air dansSuch devices are of relatively complex design due to the double rotational movement of the rotor, and furthermore are not entirely satisfactory from the point of view of the distribution of air flows in
1' espace .1 space.
D'autres appareils ont été proposés, qui présentent un corps fixe dans lequel sont disposés un rotor comportant une pluralité de pales, un moteur électrique entraînant le rotor en rotation, une grille montée en regard et en aval dudit rotor, et une conduite d'air dont l'entrée est constituée d'une ouverture placée en regard de la grille, ladite conduite d'air présentant en outre au moins un orifice de diffusion du flux d'air généré par le mouvement du rotor.Other devices have been proposed, which have a fixed body in which are arranged a rotor comprising a plurality of blades, an electric motor driving the rotor in rotation, a grid mounted opposite and downstream of said rotor, and a conduit for air, the inlet of which consists of an opening placed opposite the grid, said air duct further having at least one orifice for diffusing the air flow generated by the movement of the rotor.
Les appareils de ce type, généralement de petite taille, sont destinés à reposer à même le sol ou sur un support tel une table, le flux d'air étant diffusé à une hauteur convenable par l'intermédiaire d'une conduite d'air rigide et fixe par rapport au corps de l'appareil.Devices of this type, generally small, are intended to rest on the floor or on a support such as a table, the air flow being diffused at a suitable height by means of a rigid air duct and fixed relative to the body of the device.
Ils présentent l'avantage de ne comporter aucune partie saillante rotative, et de répartir le flux d' air généré sans recours à un mouvement rotatif oscillant supplémentaire. La conception et la fabrication de ce type d' appareils sont donc relativement simples et peu coûteuses .They have the advantage of having no rotary projecting part, and of distributing the air flow generated without recourse to an additional oscillating rotary movement. The design and manufacture of this type of apparatus is therefore relatively simple and inexpensive.
Mais là encore, la répartition des flux d'air n'est effective que dans un espace très limité, localisé suivant l'emplacement du ou des orifices de diffusion, et surtout l'encombrement de l'appareil n'est pas satisfaisant compte tenu de la dimension importante de la conduite d'air en rapport de la taille du corps fixe du ventilateur .But here again, the distribution of the air flows is effective only in a very limited space, localized according to the location of the diffusion orifice (s), and above all the size of the device is not satisfactory taking into account the large dimension of the air duct in relation to the size of the fixed body of the fan.
L'un des buts principaux de l'invention est de proposer un ventilateur domestique du dernier type décrit, qui soit de conception et de fabrication simples, qui présente un faible encombrement lorsque l'appareil n'est pas utilisé, tout en permettant une répartition relativement homogène des flux d' air dans la pièce où l'appareil est utilisé.One of the main objects of the invention is to provide a domestic fan of the last type described, which is of simple design and manufacture, which has a small footprint when the device is not used, while allowing distribution relatively homogeneous air flows in the room where the device is used.
Dans cette optique, la conduite d'air est une manche à air souple.In this context, the air line is a flexible air bag.
Grâce à cette disposition, la diffusion des flux d' air issus du ventilateur est réalisée par des moyens extrêmement simples et facilement modifiables, lesquels présentent l'avantage supplémentaire d'occuper un volume très restreint lorsque l'appareil n'est pas utilisé, pour un volume équivalent à une conduite d' air rigide de type connu en phase d'utilisation. D' autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, donnée à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels:Thanks to this arrangement, the air flows from the fan are diffused by extremely simple and easily modifiable means, which have the additional advantage of occupying a very small volume when the device is not in use, to a volume equivalent to a rigid air duct of known type in the use phase. Other characteristics and advantages of the invention will emerge from the description which follows, given by way of nonlimiting example, with reference to the appended drawings in which:
- la figure 1 est une vue en perspective éclatée suivant son axe vertical d'un ventilateur suivant 1' invention; - la figure 2 est une coupe dans un plan de symétrie vertical d'un ventilateur suivant la figure 1.- Figure 1 is an exploded perspective view along its vertical axis of a fan 1 according to the invention; - Figure 2 is a section in a vertical plane of symmetry of a fan according to Figure 1.
A la figure 1, on a représenté un ventilateur électrique 1, comprenant un corps fixe 2 qui affecte la forme d'un cadre de forme générale parallelepipedique destiné à reposer horizontalement sur un support plan, sur l'une de ses grandes faces 8. Les faces verticales périphériques 9 du cadre présentent des ouvertures 10 permettant l'entrée de l'air dans l'appareil. Le corps fixe 2 comporte un moyeu 11 d'axe vertical X, relié aux parois extérieures du cadre 2 par des ailettes radiales 12 de canalisation des flux d'air entrant dans l'appareil. La face supérieure horizontale 13 du corps fixe 2 présente une ouverture circulaire s' étendant autour de l'axe X du moyeu 11, qui constitue la sortie du flux d'air.In Figure 1, there is shown an electric fan 1, comprising a fixed body 2 which assumes the shape of a generally parallelepipedal frame intended to rest horizontally on a flat support, on one of its large faces 8. The peripheral vertical faces 9 of the frame have openings 10 allowing air to enter the device. The fixed body 2 comprises a hub 11 of vertical axis X, connected to the external walls of the frame 2 by radial fins 12 for channeling the air flows entering the device. The horizontal upper face 13 of the fixed body 2 has a circular opening extending around the axis X of the hub 11, which constitutes the outlet of the air flow.
Le ventilateur électrique comprend en outre, disposé dans le corps fixe 2 et monté à rotation sur le moyeu 11 en regard de l'ouverture de sortie du flux d' air, un rotor 3 comportant une pluralité de pales 4 conformées pour générer un mouvement d'air ascendant.The electric fan further comprises, disposed in the fixed body 2 and rotatably mounted on the hub 11 opposite the outlet opening of the air flow, a rotor 3 comprising a plurality of blades 4 shaped to generate a movement of ascending air.
Un moteur électrique 5 est placé dans le moyeu 11 du corps fixe, de façon à entraîner le rotor 3 en rotation via un axe 14. Une grille 6 de protection et de répartition du flux d'air généré par le mouvement du rotor 3, est montée en regard et en aval dudit rotor 3 sur une pièce intermédiaire 15, solidaire du corps fixe 2 par sa face supérieure 13. La grille 6 est constituée d'une couronne 16 centrée sur un moyeu 17, la face interne 18a de la couronne 16 étant rigidement reliée à la face externe 19 du moyeu 17 par des ailettes obliques 20. Les ailettes obliques 20 se situent dans des plans parallèles, inclinés par rapport à la verticale.An electric motor 5 is placed in the hub 11 of the fixed body, so as to drive the rotor 3 in rotation via an axis 14. A grid 6 for protecting and distributing the air flow generated by the movement of the rotor 3, is mounted opposite and downstream of said rotor 3 on an intermediate piece 15, integral with the fixed body 2 by its upper face 13. The grid 6 consists of a ring 16 centered on a hub 17, the internal face 18a of the ring 16 being rigidly connected to the external face 19 of the hub 17 by oblique fins 20. The oblique fins 20 are located in parallel planes, inclined to the vertical.
Le ventilateur 1 comporte également une conduite d'air 21 dont l'entrée est constituée d'une ouverture 22 placée en regard de la grille 6 de répartition, ladite conduite d'air 21 présentant en outre au moins un orificeThe fan 1 also includes an air line 21, the inlet of which consists of an opening 22 placed opposite the distribution grid 6, said air line 21 further having at least one orifice.
23 de diffusion du flux d'air.23 for diffusing the air flow.
Suivant l'invention, la conduite d'air 21 est une manche à air souple ; ainsi la mise en rotation du rotor 3 du ventilateur provoque-t-elle le gonflement de la manche à air 21 et la diffusion du flux d'air dans les directions déterminées par la forme et la position de l'orifice 23.According to the invention, the air line 21 is a flexible air bag; thus the rotation of the rotor 3 of the fan causes the swelling of the air bag 21 and the diffusion of the air flow in the directions determined by the shape and the position of the orifice 23.
Il est bien évident qu'une telle manche à air remplit la fonction de diffusion d'air de la même façon qu'une conduite d'air rigide, avec l'avantage supplémentaire de ne quasiment pas occuper de volume hors des phases d'utilisation de l'appareil, ce qui facilite considérablement le rangement et le déplacement du ventilateur.It is obvious that such a windsock fulfills the air diffusion function in the same way as a rigid air duct, with the additional advantage of practically not occupying any volume outside the phases of use. of the appliance, which considerably facilitates the storage and movement of the fan.
On peut bien sûr concevoir que la manche à air souple soit équipée de pièces pliables de rigidification, qui assurent en fin de phase d'utilisation de l'appareil, un maintien de la manche à air dans un état déplié, en l'absence d'une action de l'utilisateur.It is of course conceivable that the flexible air bag is equipped with foldable stiffening parts, which ensure at the end of the use phase of the device, maintaining the air bag in an unfolded state, in the absence of user action.
Suivant une caractéristique particulièrement intéressante de l'invention, la grille 6 est montée rotative autour d'un axe 7 sensiblement parallèle à l'axe X du rotor 3, ladite grille étant susceptible d'être entraînée en rotation par le flux d' air généré par le mouvement du rotor 3, du fait de l'incidence de l'air sur les ailettes obliques, et l'entrée 22 de la conduite d'air 21 est solidaire de la grille 6.According to a particularly advantageous characteristic of the invention, the grid 6 is rotatably mounted around an axis 7 substantially parallel to the axis X of the rotor 3, said grid being capable of being rotated by the flow of air generated by the movement of the rotor 3, due to the incidence of the air on the oblique fins, and the inlet 22 of the air duct 21 is secured to the grid 6.
De cette façon, l'air mis en mouvement par le ventilateur est diffusé suivant des directions qui peuvent être différentes de celles prédéterminées par la construction de l'ensemble formé par le rotor 3 et la grille 6 de répartition, et qui peuvent être mieux adaptées à la pièce dans laquelle l'appareil est utilisé ou au mode d'utilisation souhaité.In this way, the air set in motion by the fan is diffused in directions which may be different from those predetermined by the construction of the assembly formed by the rotor 3 and the distribution grid 6, and which can be better adapted. the room in which the appliance is used or the desired mode of use.
Comme cela apparaît sur la figure 2, une telle manche à air souple 21 peut être simplement enfilée et être maintenue par effet de serrage sur la face extérieure 18b de la couronne 16 de la grille 6, d'un organe élastique périphérique rapporté 25, solidaire de la manche à air 21.As shown in FIG. 2, such a flexible air hose 21 can be simply threaded and be held by clamping effect on the external face 18b of the crown 16 of the grid 6, of an attached peripheral elastic member 25, integral of the windsock 21.
L'entrée de la conduite d'air 21 est ainsi solidaire de façon amovible de la grille 6 de répartition, ce qui permet à l'utilisateur de facilement changer le type de conduite d'air pour des raisons d'encombrement, de mode d'utilisation ou de simples considérations esthétiques.The inlet of the air duct 21 is thus removably secured to the distribution grid 6, which allows the user to easily change the type of air duct for reasons of space, mode d use or simple aesthetic considerations.
Suivant un mode de réalisation particulier, le plan de rotation des pales 4 du rotor 3 est disposé horizontalement, et la conduite d'air 21 est de forme allongée, l'orifice de diffusion 23 étant situé dans une zone latérale sensiblement opposée à l'entrée 22 de la conduite d'air 21. Dans le mode de réalisation représenté, deux orifices de diffusion 23 sont pratiqués dans une manche à air souple 21 de forme générale conique, dont la grande base constitue l'entrée d'air 22, et dont l'autre extrémité 26 est obturée ; les orificesAccording to a particular embodiment, the plane of rotation of the blades 4 of the rotor 3 is arranged horizontally, and the air duct 21 is of elongated shape, the diffusion orifice 23 being located in a lateral zone substantially opposite to the inlet 22 of the air duct 21. In the embodiment shown, two orifices diffusion 23 are formed in a flexible air sleeve 21 of generally conical shape, whose large base constitutes the air inlet 22, and whose other end 26 is closed; the orifices
23 sont situés dans la partie latérale supérieure du cône, ce qui permet d'obtenir un appareil susceptible d'être posé à même le sol, diffusant de l'air à une hauteur supérieure, sur 360° autour de l'axe X de rotation de la grille 6.23 are located in the upper lateral part of the cone, which makes it possible to obtain a device capable of being placed on the ground, diffusing air at a higher height, over 360 ° around the axis X of rotation from grid 6.
Le ventilateur suivant l'invention comporte de préférence un système de réglage de la vitesse de rotation de la grille de répartition, composé d'un freinThe fan according to the invention preferably comprises a system for adjusting the speed of rotation of the distribution grid, composed of a brake
24 solidaire de la pièce intermédiaire 15, portant sur la face externe 18b de la couronne 16.24 secured to the intermediate part 15, bearing on the external face 18b of the crown 16.
Afin d'assurer une diffusion uniforme de l'air dans un espace important entourant l'appareil, il peut être avantageux de prévoir que la conduite d'air 21 est constituée au moins en partie d'une matière poreuse, telle par exemple qu'un tissu.In order to ensure uniform diffusion of the air in a large space surrounding the device, it may be advantageous to provide that the air line 21 is made at least in part of a porous material, such as for example that tissue.
Un ventilateur du type qui vient d'être décrit constitue d' abord un appareil peu encombrant présentant de bonnes performances de diffusion d'air ; il permet ensuite, par simple changement d'un accessoire, de modifier la distribution d'air sur un même appareil. De plus, un tel appareil présente des possibilités d'adaptation à des critères esthétiques très divers, et peut même constituer un objet de décoration animé. A fan of the type which has just been described firstly constitutes a space-saving device having good air diffusion performance; it then allows, by simply changing an accessory, to modify the air distribution on the same device. In addition, such a device has possibilities of adaptation to very diverse aesthetic criteria, and can even constitute an animated decorative object.
