Abstract
Description
Le séchage des mains par air chaud présente l'avantage d'être beaucoup plus économique que le séchage à l'aide d'une serviette et en particulier d'une serviette en papier jetable, tout en étant aussi hygiénique que cette dernière. Les seche-mains à air chaud comportent un ventilateur qui aspire l'air extérieur et le refoule après l'avoir fait passer sur un moyen de chauffage.Drying hands by hot air has the advantage of being much more economical than drying using a towel and in particular a disposable paper towel, while being as hygienic as the latter. Hot air dryers have a fan that draws in air from the outside and blows it out after passing it over a heating medium.
Lorsqu'on veut obtenir un debit donné de gaz, il est connu de produire du gaz à haute pression et de transmettre l'énergie d'une partie de ce gaz à un gaz à basse pression de façon à obtenir un mélange à une pression dont le débit est supérieur à celui du gaz à haute pression et qui se trouve intermédiaire entre la pression motrice et la pression d'aspiration. On utilise souvent à cet effet des trompes à induction.When it is desired to obtain a given gas flow rate, it is known to produce gas at high pressure and to transmit the energy of part of this gas to a gas at low pressure so as to obtain a mixture at a pressure of which the flow rate is higher than that of the high pressure gas and which is intermediate between the driving pressure and the suction pressure. Induction tubes are often used for this purpose.
La présente invention concerne un appareil de séchage à air chaud, tel qu'un sèche-mains ou un seche-cheveux, comportant un ventilateur, une trompe à induction, et des moyens de chauffage de l'air refoulé.The present invention relates to a hot air drying apparatus, such as a hand dryer or a hair dryer, comprising a fan, an induction pump, and means for heating the discharged air.
Cet appareil de séchage est caractérisé en ce que le ventilateur est disposé dans une enceinte qui délimite une chambre de compression et comporte à sa périphérie une ou plusieurs fentes profilées dirigées vers le col de la trompe à induction. L'air moteur est ainsi produit directement dans la trompe à induction.This drying device is characterized in that the fan is arranged in an enclosure which delimits a compression chamber and comprises at its periphery one or more profiled slots directed towards the neck of the induction tube. Motor air is thus produced directly in the induction tube.
Dans un mode de réalisation avantageux de 11 invention, les moyens de chauffage de l'air refoulé comprennent une source de rayons infra-rouges, par exemple une lampe à halogène, dont le faisceau est dirigé vers une ou plusieurs tôles au contact desquelles passe l'air refoulé.In an advantageous embodiment of the invention, the means for heating the discharged air comprise a source of infrared rays, for example a halogen lamp, the beam of which is directed towards one or more sheets in contact with which passes the exhausted air.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation d'un sèche-mains selon l'invention, avec référence au dessin annexé dans lequel
La Figure 1 représente le sèche-mains vu par
en dessous;
La Figure 2 en est une coupe suivant II-II de la
Figure 1.An embodiment of a hand dryer according to the invention has been described below, by way of non-limiting example, with reference to the appended drawing in which
Figure 1 shows the hand dryer seen by
below;
Figure 2 is a section along II-II of the
Figure 1.
Tel qu'il est représenté au dessin, le sèche-mains selon l'invention comprend un bottier 1 à l'intérieur duquel se trouve un élément cylindrique 2 dont les faces latérales sont ouvertes et qui comporte une ou plusieurs ouvertures profilées 3. Dans cet élément se trouve un ventilateur-compresseur 4; ce dernier est entrainé par un moteur électrique 5 qui est solidaire du ventilateur 4 alors que son axe 6 est fixe et solidaire de la paroi latérale du bottier 1.As shown in the drawing, the hand dryer according to the invention comprises a case 1 inside which there is a cylindrical element 2 whose side faces are open and which has one or more profiled openings 3. In this element is a fan-compressor 4; the latter is driven by an electric motor 5 which is integral with the fan 4 while its axis 6 is fixed and integral with the side wall of the boot 1.
Le fond la du bottier 1 comporte à proximité de l'un de ses bords longitudinaux une ouverture d'entrée d'air 7 qui s'étend sensiblement sur toute la largeur du bottier et à proximité de son autre bord longitudinal, une seconde ouverture d'entrée d'air 8. Le bot- tier 1 contient, au voisinage de son fond la, une série de tôles parallèles 9 qui est surmontée d'une lampe à halogène 10 placée au foyer d'un réflecteurll dirigé sur les tôles. Ces tôles s'étendent sur toute la largeur du boitier.The bottom 1a of the case 1 comprises, near one of its longitudinal edges, an air inlet opening 7 which extends substantially over the entire width of the case, and near its other longitudinal edge, a second opening d 'air inlet 8. The housing 1 contains, in the vicinity of its bottom 1a, a series of parallel sheets 9 which is surmounted by a halogen lamp 10 placed at the focus of a reflector 11 directed on the sheets. These sheets extend over the entire width of the housing.
La ou les ouvertures périphériques 3 sont orientées vers le col d'une tuyère 12 qui forme trompe à induction et devant l'entrée de laquelle se trouve une ouverture d'entrée d'air secondaire 13 ménagée dans le boîtier. Une ouverture de sortie d'air 14 est ménagée dans le fond la du boîtier en regard de la tuyère 12 et au-delà de celle-ci.Or the peripheral openings 3 are oriented towards the neck of a nozzle 12 which forms an induction horn and in front of the inlet of which there is a secondary air inlet opening 13 formed in the housing. An air outlet opening 14 is formed in the bottom 1a of the housing opposite the nozzle 12 and beyond it.
Un commutateur non représenté au dessin permet simultanément de mettre en marche le moteur 5 et d'allumer l'ampoule 10.A switch not shown in the drawing simultaneously makes it possible to start the motor 5 and to light the bulb 10.
En fonctionnement, l'ampoule 10 chauffe les tôles 9.In operation, the bulb 10 heats the sheets 9.
Le ventilateur 4 aspire de l'air qui pénètre dans le boîtier 1 par les ouvertures 7 et 8, puis dans l'éld- ment cylindrique 2 qui délimite une chambre de compression. Cet air sort de l'élément 2 par sa ou ses fen tes3etpénetre dans la tuyère 12. Sous l'effet de la dépression créée à l'entrée de la tuyère par la circulation de cet air, de l'air secondaire y est aspiré de l'extérieur par l'ouverture 13. Le mélange d'air primaire et secondaire est soufflé à l'extérieur par l'ouverture 14, après avoir été réchauffé par son passage entre les tôles 9. Ces tôles qui forment un échangeur, jouent également un rôle de redresseur du flux d'air et un rôle dé protection en empêchant la main de pénétrer dans le boîtier. L'air chaud ainsi soufflé assure le séchage des mains qui sont placées à une faible distance en dessous de l'ouverture 14; les mains sont également séchées par le rayonnement infra-rouge qui passe entre les tôles 9 et sort par l'ouverture 14.The fan 4 draws in air which enters the housing 1 through the openings 7 and 8, then into the cylindrical element 2 which delimits a compression chamber. This air leaves element 2 through its window or windows 3 and penetrates into the nozzle 12. Under the effect of the vacuum created at the inlet of the nozzle by the circulation of this air, secondary air is sucked therefrom. outside through the opening 13. The primary and secondary air mixture is blown outside through the opening 14, after being heated by its passage between the sheets 9. These sheets which form an exchanger, also play a role of air flow rectifier and a protective role by preventing the hand from entering the case. The hot air thus blown ensures the drying of the hands which are placed a short distance below the opening 14; the hands are also dried by the infrared radiation which passes between the sheets 9 and leaves through the opening 14.
I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
