Description

SECHE-CHEVEUX A DISPOSITIF DE VARIATION DE LA SECTION DE HAIR DRYER WITH DEVICE FOR VARIATION OF THE SECTION OF
SORTIE DU FLUX D'AIRAIR FLOW OUTLET
La présente invention concerne un appareil de séchage et/ou ou de mise en forme des cheveux, plus particulièrement un sèche-cheveux, comportant un dispositif de variation de la section de sortie du flux d'air soufflé par ce dernier.The present invention relates to an apparatus for drying and / or shaping the hair, more particularly a hair dryer, comprising a device for varying the outlet section of the air flow blown by the latter.
Les sèche-cheveux à usage privé ou professionnel comprennent généralement un boîtier muni d'une poignée et équipé de moyens de circulation de l'air entre une grille d'entrée dans le boîtier et un orifice de sortie de ce dernier, ainsi que de moyens de chauffage de l'air soufflé. Les moyens de circulation de l'air sont constitués par un ventilateur entraîné par un moteur électrique. Le problème qui se pose souvent avec ces appareils est comment modifier l'intensité et la forme du flux d'air sortant de ce dernier afin de l'adapter à différents styles de coiffure.Hair dryers for private or professional use generally comprise a housing provided with a handle and equipped with means for circulating air between an inlet grille in the housing and an outlet orifice thereof, as well as means for heating the supply air. The air circulation means are constituted by a fan driven by an electric motor. The problem that often arises with these devices is how to modify the intensity and the shape of the air flow leaving it in order to adapt it to different styles of hairstyle.
Pour résoudre ce problème, la plupart des appareils utilisent plusieurs accessoires amovibles montés sur l'extrémité soufflante de l'appareil. Chaque accessoire constitue une buse de sortie de forme et fonction déterminée et, par conséquent, pour passer d'une forme à l'autre ou pour varier le type de séchage il faut changer d'accessoire. Ceci présente l'inconvénient de devoir changer en cours de séchage plusieurs accessoires, ce qui devient gênant surtout que les accessoires sont montés à proximité des moyens de chauffage. Un autre inconvénient est de multiplier le nombre d'accessoires, et donc d'occuper une place importante dans l'espace de rangement prévu pour l'appareil, tout en disposant d'un nombre limité de formes et intensités du flux d'air.To solve this problem, most devices use several removable accessories mounted on the blowing end of the device. Each accessory constitutes an outlet nozzle of determined shape and function and, therefore, to switch from one form to another or to vary the type of drying, it is necessary to change the accessory. This has the drawback of having to change several accessories during drying, which becomes annoying especially since the accessories are mounted near the heating means. Another disadvantage is to multiply the number of accessories, and therefore to occupy an important place in the storage space provided for the device, while having a limited number of shapes and intensities of the air flow.
D'autres sèche-cheveux, notamment ceux décrits dans les documents FR 1 546 750 ou US 4 977 306 utilisent chacun une paire de volets mobiles articulés autour des axes situés à l'intérieur du conduit d'évacuation de l'air chaud de manière à obturer plus ou moins ce conduit. Ainsi, on peut restreindre plus ou moins la section libre du conduit d'air par pivotement des volets autour de leur axe d'articulation, mais la section de passage nouvellement créée n'étant pas visible de l'extérieur, il devient difficile de choisir l'orientation du sèche-cheveux par rapport à la mèche de cheveux. Ceci est incommode en début de séchage et devient gênant au cours de l'opération quand il faut coordonner continuellement la position des volets au degré de séchage ou de mise en forme de la coiffure. De surcroît, les dispositifs de variation de flux sont intégrés à la construction de l'appareil, ils ne sont pas prévus en tant qu'accessoires de ce dernier.Other hair dryers, in particular those described in the documents FR 1 546 750 or US 4 977 306 each use a pair of movable flaps articulated around the axes located inside the exhaust duct of the hot air so to more or less seal this conduit. Thus, one can more or less restrict the free section of the air duct by pivoting the flaps around of their axis of articulation, but the newly created passage section not being visible from the outside, it becomes difficult to choose the orientation of the hairdryer relative to the lock of hair. This is inconvenient at the start of drying and becomes troublesome during the operation when it is necessary to continually coordinate the position of the flaps with the degree of drying or shaping of the hairstyle. In addition, the flow variation devices are integrated into the construction of the device, they are not intended as accessories of the latter.
Dans d'autres documents, tels le FR 2 640 857 ou le WO 00/33697, le changement de section de sortie est visible, mais les mécanismes utilisés pour modifier cette section permettent à l'appareil de délivrer soit un flux d'air de section cylindrique, soit un flux d'air de section plate, sans position intermédiaire entre les deux. En outre, dans le premier document, le FR 2 640 857 au nom de la demanderesse, la buse de sortie est réalisée en un matériau élastiquement déformable, le mécanisme utilisé pour la modeler s'avérant assez complexe. En ce qui concerne le document WO 00/33697, deux tiroirs pivotent perpendiculairement à l'axe longitudinal de l'appareil et font saillie latéralement pour obtenir la position jet plat, ce qui fait que l'appareil délivre un jet d'air dévié sur les côtés, et non pas concentré au centre pour fixer localement la coiffure; de plus, les deux tiroirs latéraux augmentent le gabarit et l'encombrement de la buse.In other documents, such as FR 2 640 857 or WO 00/33697, the change in outlet section is visible, but the mechanisms used to modify this section allow the device to deliver either an air flow of cylindrical section, a flat section air flow, without intermediate position between the two. In addition, in the first document, FR 2 640 857 in the name of the applicant, the outlet nozzle is made of an elastically deformable material, the mechanism used to shape it being quite complex. With regard to document WO 00/33697, two drawers pivot perpendicularly to the longitudinal axis of the device and protrude laterally to obtain the flat jet position, which means that the device delivers a deflected air jet on the sides, and not concentrated in the center to fix the hairstyle locally; in addition, the two side drawers increase the size and size of the nozzle.
Un autre type d'accessoire utilisé pour dévier le flux d'air produit par un sèche- cheveux est décrit dans le document WO 97/09899. Cet accessoire est un diffuseur destiné à être fixé à la sortie d'un sèche-cheveux, le diffuseur comportant un corps creux muni à une extrémité soufflante d'orifices de sortie d'air et d'autres orifices traversés par des doigts creux à l'extrémité libre desquels sont également pratiqués des orifices de sortie de l'air soufflé par l'appareil. L'appareil comporte par ailleurs un dispositif apte à faire varier la longueur des doigts de manière à ce qu'ils s'écartent plus ou moins du cuir chevelu et qu'ils envoient un flux d'air diffus. Ce type d'accessoire ne permet pas d'obtenir un flux d'air concentré pour fixer la coiffure et il est par ailleurs très encombrant. De surcroît, un diffuseur ayant un volume important ne permet pas non plus d'accélérer un flux d'air. Si une petite accélération a lieu, elle perturbe le flux d'air devenu très turbulent du fait d'un nombre important de variation de sections, ce qui génère des difficultés de régulation en température du flux d'air sortant du diffuseur.Another type of accessory used to divert the air flow produced by a hair dryer is described in document WO 97/09899. This accessory is a diffuser intended to be fixed at the outlet of a hair dryer, the diffuser comprising a hollow body provided at a blowing end with air outlet orifices and other orifices through which hollow fingers pass through. 'free end of which are also formed outlets for the air blown by the device. The apparatus also includes a device capable of varying the length of the fingers so that they move more or less away from the scalp and that they send a diffuse air flow. This type of accessory does not allow to obtain a concentrated air flow to fix the hairstyle and it is also very bulky. In addition, a diffuser having a large volume also does not accelerate an air flow. If a small acceleration takes place, it disturbs the air flow which has become very turbulent due to a large number of variation in sections, which generates difficulties in regulating the temperature of the air flow leaving the diffuser.
Le but de la présente invention est de remédier aux inconvénients précités et de proposer un sèche-cheveux muni d'un dispositif de variation continue de la section de sortie du flux d'air soufflé par l'appareil, permettant de passer progressivement d'un flux éclaté multidirectionnel à un flux concentré monodirectionnel et vice-versa, tout en utilisant un dispositif compact et de construction simplifiée.The object of the present invention is to remedy the aforementioned drawbacks and to provide a hair dryer provided with a device for continuously varying the outlet section of the air flow blown by the device, making it possible to progressively pass from one multidirectional burst flow to a concentrated unidirectional flow and vice versa, while using a compact device and of simplified construction.
Un autre but de l'invention est un sèche-cheveux muni d'un dispositif permettant de varier la forme de la section de sortie du flux d'air soufflé par l'appareil, tout en permettant de visualiser la forme de la section ainsi modifiée.Another object of the invention is a hair dryer provided with a device allowing the shape of the outlet section of the air flow blown by the device to be varied, while allowing the shape of the section thus modified to be viewed. .
Un but supplémentaire de l'invention est un sèche-cheveux muni d'un dispositif de variation du flux d'air qui soit efficace, fiable en fonctionnement et facile à industrialiser pour un moindre coût de fabrication.A further object of the invention is a hair dryer provided with a device for varying the air flow which is efficient, reliable in operation and easy to industrialize for a lower manufacturing cost.
Ces buts sont réalisés avec un sèche-cheveux comportant un boîtier comprenant des moyens pour faire circuler un flux d'air entre une extrémité d'entrée et une extrémité de sortie dudit boîtier, ainsi qu'un dispositif agencé à proximité de l'extrémité de sortie permettant de modifier la section de sortie du flux d'air, ledit dispositif comportant au moins deux volets agencés dans le flux d'air ainsi que des moyens d'actionnement en pivotement desdits volets, du fait que ledit dispositif comporte une buse tubulaire disposée entre les deux volets et mobile axialement par rapport au flux d'air.These purposes are achieved with a hair dryer comprising a housing comprising means for circulating an air flow between an inlet end and an outlet end of said housing, as well as a device arranged near the end of outlet making it possible to modify the outlet section of the air flow, said device comprising at least two flaps arranged in the air flow as well as means for pivotally actuating said flaps, owing to the fact that said device comprises a tubular nozzle disposed between the two flaps and movable axially with respect to the air flow.
Le dispositif modifiant la section de sortie du flux d'air comprend donc au moins deux volets pivotants agencés de part et d'autre d'une buse tubulaire, disposée de préférence au centre du dispositif, l'axe longitudinal du dispositif étant dans la prolongation de l'axe longitudinal du sèche-cheveux, parallèle au flux d'air. Les volets sont agencés pour pivoter autour des axes de pivotement qui peuvent être parallèles, perpendiculaires ou même inclinés par rapport au flux d'air de manière à obturer lors de leur mouvement la section de sortie du flux d'air. Ainsi, cette section de sortie varie entre une valeur maximale quand les volets laissent passer le flux d'air soufflé par l'appareil, en l'orientant ou pas vers l'extérieur, et une valeur minimale quand ils obturent ce passage. La buse tubulaire étant située entre les deux volets, le flux d'air est canalisé pour sortir du dispositif à travers cette dernière au moment de l'obturation de la section de sortie de l'air par les volets.The device modifying the air flow outlet section therefore comprises at least two pivoting flaps arranged on either side of a tubular nozzle, preferably arranged in the center of the device, the longitudinal axis of the device being in the extension of the longitudinal axis of the hair dryer, parallel to the air flow. The flaps are arranged to pivot around the pivot axes which can be parallel, perpendicular or even inclined relative to the air flow so as to close during their movement the air flow outlet section. Thus, this outlet section varies between a maximum value when the shutters allow the flow of air blown by the device to pass, orienting it or not towards the outside, and a minimum value when they close this passage. The tubular nozzle being located between the two flaps, the air flow is channeled out of the device through the latter when the air outlet section is closed by the flaps.
La buse étant mobile axialement, elle arrive à faire saillie par rapport au boîtier lors de son mouvement, ce qui permet à l'utilisateur de bien l'orienter par rapport à la zone de mise en forme ou de séchage des cheveux. La buse peut être déplacée en même temps que les volets par un même mécanisme ou en utilisant des mécanismes séparés d'actionnement, ou, dans une variante elle pourrait être déplacée de manière décalée dans le temps, le mécanisme d'actionnement utilisé pouvant déplacer initialement les volets et la buse par la suite ou vice-versa.The nozzle being axially movable, it arrives to project relative to the housing during its movement, which allows the user to orient it well with respect to the shaping or drying area of the hair. The nozzle can be moved at the same time as the flaps by the same mechanism or by using separate actuation mechanisms, or, as a variant, it could be displaced in a time-shifted manner, the actuation mechanism used being able to initially move the flaps and the nozzle thereafter or vice versa.
Ainsi, lorsque les volets sont en position d'ouverture maximale, l'air soufflé peut prendre toute direction imprimée par le conduit de sortie de l'appareil ou il peut être guidé, notamment vers l'extérieur par la forme des volets. Au fur et à mesure que les volets pivotent, ils se rabattent vers la buse de manière à diriger le flux d'air dans l'espace compris entre les volets et la buse. On obtient ainsi au début un flux d'air diffus à directions multiples et à la fin un flux d'air concentré unidirectionnel, ainsi que toutes les positions intermédiaires entre ces deux positions extrêmes, le passage d'une position à l'autre pouvant se faire de manière continue ou intermittente.Thus, when the flaps are in the fully open position, the blown air can take any direction printed by the outlet duct of the device or it can be guided, in particular outwards by the shape of the flaps. As the flaps pivot, they fold down towards the nozzle so as to direct the air flow in the space between the flaps and the nozzle. This gives a diffuse air flow in multiple directions at the beginning and a concentrated unidirectional air flow at the end, as well as all the intermediate positions between these two extreme positions, the passage from one position to the other being possible. do it continuously or intermittently.
On peut donc obtenir diverses formes pour la section de sortie du flux d'air, et donc, diverses intensités pour le flux d'air soufflé par le sèche-cheveux, en passant d'un flux d'air diffus, de faible intensité, utile notamment pour le début de séchage de la chevelure, jusqu'à un flux d'air fort et concentré qui peut être dirigé facilement vers une boucle à fixer ou toute autre zone de chevelure afin de faciliter la mise en forme de la coiffure.We can therefore obtain various shapes for the air flow outlet section, and therefore, various intensities for the air flow blown by the hair dryer, passing from a diffuse air flow, of low intensity, useful especially for the start drying the hair, until a strong and concentrated air flow which can be easily directed towards a loop to fix or any other area of hair in order to facilitate the shaping of the hairstyle.
De préférence, ladite buse est mobile en translation.Preferably, said nozzle is movable in translation.
On pourrait, certes, imaginer le déplacement de la buse en direction axiale selon un mouvement hélicoïdal ou tout autre mouvement combiné ayant une composante axiale. Toutefois, on a choisi un mouvement en translation axiale de la buse pour des raisons de simplification constructive et également pour obtenir un écoulement laminaire du flux d'air à travers la buse, plus indiqué pour fixer une coiffure.One could, of course, imagine the displacement of the nozzle in the axial direction in a helical movement or any other combined movement having an axial component. However, an axial translation movement of the nozzle was chosen for reasons of constructive simplification and also to obtain a laminar flow of the air flow through the nozzle, more suitable for fixing a hairstyle.
Avantageusement, le dispositif selon l'invention comprend des moyens de commande qui actionnent en même temps le déplacement de la buse et celui des volets.Advantageously, the device according to the invention comprises control means which actuate at the same time the movement of the nozzle and that of the flaps.
Ceci simplifie beaucoup l'usage et le confort d'utilisation du sèche-cheveux muni d'un tel dispositif, car avec un seul moyen de commande on peut régler l'intensité du flux d'air soufflé et la position de la buse.This greatly simplifies the use and comfort of use of the hair dryer fitted with such a device, because with a single control means the intensity of the blown air flow and the position of the nozzle can be adjusted.
De préférence, lesdits moyens de commande comprennent une bague mobile en rotation.Preferably, said control means comprise a ring movable in rotation.
Le dispositif de variation de la section de sortie du flux d'air est agencé à l'extrémité de sortie d'air du sèche-cheveux, pour ceci, il est configuré de manière à s'adapter à la forme du boîtier, il est donc de forme cylindrique. Une bague ayant la même forme et un diamètre d'une valeur comparable à celui du conduit de sortie d'air du sèche-cheveux peut être facilement entraînée en rotation par la main de l'utilisateur, le mouvement de la bague pouvant alors être utilisé pour actionner la buse et/ou les volets. Ceci confère l'avantage d'avoir une construction compacte tout en bénéficiant d'une bonne amplitude du mouvement de commande. Avantageusement, le dispositif de l'invention comprend un premier mécanisme qui transforme le mouvement de rotation de la bague en un mouvement de translation de la buse et un deuxième mécanisme qui transforme le mouvement de translation de la buse ou de rotation de la bague en un mouvement de pivotement des volets, au moins l'un desdits mécanismes étant commandé par la bague rotative.The device for varying the air flow outlet section is arranged at the air outlet end of the hair dryer, for this it is configured to adapt to the shape of the housing, it is therefore cylindrical in shape. A ring having the same shape and a diameter of a value comparable to that of the air outlet duct of the hair dryer can be easily rotated by the hand of the user, the movement of the ring can then be used to operate the nozzle and / or the flaps. This gives the advantage of having a compact construction while benefiting from a good amplitude of the control movement. Advantageously, the device of the invention comprises a first mechanism which transforms the rotational movement of the ring into a translational movement of the nozzle and a second mechanism which transforms the translational movement of the nozzle or of rotation of the ring into a pivoting movement of the flaps, at least one of said mechanisms being controlled by the rotary ring.
Ainsi, la rotation de la bague peut agir directement sur le pivotement des volets qui agissent à leur tour sur le déplacement de la buse ou, inversement, la bague peut entraîner la buse qui entraîne, à son tour, les volets. Une telle construction permet par un simple actionnement de la bague rotative d'obtenir tous les mouvements souhaités des volets et de la buse d'une manière simple et efficace en fonctionnement.Thus, the rotation of the ring can act directly on the pivoting of the flaps which in turn act on the movement of the nozzle or, conversely, the ring can drive the nozzle which in turn drives the flaps. Such a construction allows, by a simple actuation of the rotary ring, to obtain all the desired movements of the flaps and of the nozzle in a simple and efficient manner in operation.
De préférence, ledit premier mécanisme est constitué par un ergot solidaire de la surface extérieure d'un corps de buse qui se déplace dans une rainure hélicoïdale pratiquée sur la surface intérieure de la bague de commande.Preferably, said first mechanism consists of a lug secured to the outer surface of a nozzle body which moves in a helical groove made on the inner surface of the control ring.
Ainsi, la rotation de la bague de commande autour de l'axe longitudinal de l'appareil, qui est celui du flux d'air au centre du dispositif, est transformée en une translation de la buse au long du même axe. Une telle construction s'avère très simple constructivement et fiable en fonctionnement.Thus, the rotation of the control ring around the longitudinal axis of the device, which is that of the air flow in the center of the device, is transformed into a translation of the nozzle along the same axis. Such a construction turns out to be very simple constructively and reliable in operation.
Avantageusement, ledit deuxième mécanisme est constitué par un ergot, solidaire d'une extrémité du volet, se déplaçant dans une rainure inclinée pratiquée sur la surface intérieure du corps de buse.Advantageously, said second mechanism consists of a lug, integral with one end of the flap, moving in an inclined groove made on the inner surface of the nozzle body.
Le mouvement en translation du corps de buse, supportant la buse en sa partie centrale, est utilisé pour déplacer en pivotement le volet lorsqu'un ergot, solidaire d'une des extrémités du volet, suit le cheminement imposé par une rainure inclinée pratiquée sur la surface intérieure du corps de buse. Cette construction en étant très simple à réaliser, est très bien adaptée à l'entraînement de plusieurs volets en même temps, tout en restant d'un encombrement réduit.The translational movement of the nozzle body, supporting the nozzle in its central part, is used to pivot the shutter when a lug, integral with one of the ends of the shutter, follows the path imposed by an inclined groove made on the inner surface of the nozzle body. This construction, being very simple to carry out, is very well suited to the training of several flaps at the same time, while remaining compact.
De préférence, l'ergot solidaire d'un des volets se déplace dans une rainure inclinée dans un sens et l'ergot solidaire du volet opposé se déplace dans une rainure diamétralement opposée à la première et inclinée dans le sens contraire.Preferably, the lug secured to one of the flaps moves in a groove inclined in one direction and the lug secured to the opposite flap moves in a groove diametrically opposite the first and inclined in the opposite direction.
Ainsi, on obtient deux pivotements simultanés, mais dans des sens opposés des deux volets situés de part et d'autre de la buse, un des volets tournant dans le sens des aiguilles d'une montre et l'autre dans un sens trigonométrique, ce qui fait que les volets se ferment progressivement, de préférence vers la buse, en canalisant l'air dans un filet de plus en plus étroit jusqu'à ce qu'ils deviennent tangents à la buse et ferment complètement l'espace existant entre les volets et la buse.Thus, two simultaneous pivotings are obtained, but in opposite directions of the two flaps located on either side of the nozzle, one of the flaps rotating clockwise and the other in a trigonometric direction, this which causes the flaps to close gradually, preferably towards the nozzle, by channeling the air in an increasingly narrow net until they become tangent to the nozzle and completely close the space existing between the flaps and the nozzle.
De manière avantageuse, les valeurs de la surface libre de la section de sortie varient lors du déplacement des volets dans une plage comprise entre 2:1 et 14:1 , de préférence entre 3:1 et 8:1.Advantageously, the values of the free area of the outlet section vary during the movement of the flaps in a range between 2: 1 and 14: 1, preferably between 3: 1 and 8: 1.
Lors des essais effectués on a constaté qu'en déterminant les dimensions des volets et de la buse on arrive à obtenir des modifications de la section de sortie dans les plages énoncées, et donc de concentrer le flux d'air de manière optimale pour sécher et fixer la coiffure, sans être trop agressif pour les cheveux. On a également constaté qu'une réduction de la surface de la section de sortie dans ces limites permettrait une utilisation en continu, sans coupure du thermostat déclenchée par échauffement excessif de l'élément chauffant.During the tests carried out, it was found that by determining the dimensions of the flaps and the nozzle, it is possible to obtain modifications of the outlet section within the stated ranges, and therefore to concentrate the air flow optimally for drying and fix the hairstyle, without being too aggressive for the hair. It has also been found that a reduction in the area of the outlet section within these limits would allow continuous use, without cutting off the thermostat triggered by excessive heating of the heating element.
De préférence, le dispositif de l'invention est fixé de manière amovible au boîtier du sèche-cheveux.Preferably, the device of the invention is removably attached to the housing of the hair dryer.
Ceci permet d'enlever le dispositif et de le nettoyer ou, également, d'utiliser le sèche-cheveux sans embout ou encore de monter d'autres accessoires sur le sèche-cheveux. D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lumière de la description et des dessins qui suivent, illustrant, à titre d'exemples non limitatifs, un mode de mise en œuvre de l'invention. Ainsi, référence est faite aux figures 1 à 5, où : - la figure 1 est une vue en perspective d'un sèche-cheveux équipé d'un dispositif de variation de la section de sortie d'air conforme à l'invention;This makes it possible to remove the device and clean it or, also, to use the hairdryer without a nozzle or to mount other accessories on the hair dryer. Other characteristics and advantages of the invention will appear more clearly in the light of the description and of the drawings which follow, illustrating, by way of nonlimiting examples, an embodiment of the invention.

Tel que visible à la figure 1 , le sèche-cheveux réalisé conformément à l'invention comporte un boîtier 1 à l'intérieur duquel sont agencés un ventilateur actionné en rotation par un moteur électrique assurant la circulation de l'air entre une entrée 4 située à l'arrière du boîtier 1 et une sortie 5 située à l'extrémité opposée, des moyens de chauffage du flux d'air circulant à l'intérieur de l'appareil ainsi que des raccords à une alimentation électrique. La mise en marche et l'arrêt de l'appareil se font en actionnant un interrupteur 9.As shown in Figure 1, the hair dryer produced in accordance with the invention comprises a housing 1 inside which are arranged a fan actuated in rotation by an electric motor ensuring the circulation of air between an inlet 4 located at the rear of the housing 1 and an outlet 5 located at the opposite end, means for heating the air flow circulating inside the device as well as connections to an electrical supply. The device is switched on and off by actuating a switch 9.
Le sèche-cheveux comporte également un dispositif 3 permettant de modifier la forme de la section de sortie d'air S, ce dispositif étant fixé à l'extrémité de sortie d'air 5. Le dispositif 3 peut être fixé de manière permanente à l'extrémité 5 du boîtier 1ou il peut également être monté amovible par rapport au boîtier 1 , par exemple par une fixation à baïonnette, par un assemblage forcé, etc .The hair dryer also includes a device 3 making it possible to modify the shape of the air outlet section S, this device being fixed to the air outlet end 5. The device 3 can be permanently fixed to the end 5 of the housing 1 or it can also be removably mounted relative to the housing 1, for example by a bayonet fixing, by a forced assembly, etc.
Tel que mieux visible à la figure 2, le dispositif 3 comprend un support tubulaire 10 qui porte les autres éléments du dispositif et qui comporte, à l'une des ses extrémités, des tétons 11 qui s'engagent dans des canaux de forme correspondante à l'extrémité 5 du boîtier 1 pour fixer le dispositif 3 à l'appareil par une fixation du type à baïonnettes. L'extrémité opposée du support 10 se termine par un rebord périphérique 15 servant de butée pour une bague périphérique 28. Le support 10 comporte, sur une partie de sa surface extérieure, deux entailles 16 disposées parallèlement à son axe longitudinal, de part et d'autre de ce dernier, et formant guidages en translation pour un corps de buse 12 qui sera décrit plus loin.As best seen in Figure 2, the device 3 comprises a tubular support 10 which carries the other elements of the device and which comprises, at one of its ends, pins 11 which engage in channels of corresponding shape at the end 5 of the housing 1 to fix the device 3 to the device by a bayonet type fixing. The opposite end of the support 10 ends in a peripheral rim 15 serving as a stop for a peripheral ring 28. The support 10 comprises, on a part of its outer surface, two notches 16 arranged parallel to its longitudinal axis, on the right and 'other of the latter, and forming guides in translation for a nozzle body 12 which will be described later.
Deux fenêtres 14 diamétralement opposées sont découpées dans le support 10 et leurs bords servent de maintien pour deux cages : supérieure 18a et inférieure 18b. Les cages 18a, 18b ont chacune une forme de secteur de cylindre et comportent des orifices traversants 19a de réception des axes de rotation 22a, 23a des volets supérieurs 6a, 8a, et respectivement des orifices traversants 19b de réception des axes de rotation 22b,23b des volets inférieurs 6b, 8b. Les cages sont réalisées sous forme de deux pièces à part, fixées par pression dans les fenêtres 14, ceci afin de simplifier la fabrication et faciliter ensuite le montage de l'ensemble des pièces du dispositif. On aurait pu également prévoir les deux cages 18a, 18b réunies en une seule pièce annulaire réalisée en un matériau élastique et fixée par son élasticité autour du support 10.Two diametrically opposite windows 14 are cut from the support 10 and their edges serve to hold two cages: upper 18a and lower 18b. The cages 18a, 18b each have the shape of a cylinder sector and comprise through holes 19a for receiving the axes of rotation 22a, 23a of the upper flaps 6a, 8a, and respectively through holes 19b for receiving the axes of rotation 22b, 23b lower flaps 6b, 8b. The cages are produced in the form of two separate parts, fixed by pressure in the windows 14, this in order to simplify the manufacture and then facilitate the assembly of all the parts of the device. One could also have provided the two cages 18a, 18b joined together in a single annular piece made of an elastic material and fixed by its elasticity around the support 10.
Dans l'exemple présenté aux figures annexées il a été prévu d'utiliser quatre volets : deux supérieurs 6a, 8a, situés en la partie supérieure du dispositif 3 par rapport à son axe central, et deux volets inférieurs 6b,8b situés du côté opposé, symétriquement aux premiers par rapport à l'axe central du dispositif 3.In the example presented in the appended figures, provision has been made to use four flaps: two upper flaps 6a, 8a, located in the upper part of the device 3 relative to its central axis, and two lower flaps 6b, 8b located on the opposite side , symmetrically to the first with respect to the central axis of the device 3.
Tel qu'on peut le remarquer sur les dessins, chaque volet 6a,6b,8a,8b présente une forme d'ailette recourbée, ayant une section longitudinale en arc de cercle.As can be seen in the drawings, each flap 6a, 6b, 8a, 8b has the shape of a curved fin, having a longitudinal section in an arc.
Chaque volet supérieur 6a,8a comporte deux saillies formant axes de pivotement 22a, respectivement 23a situés aux extrémités du volet de manière à ce que chaque axe est soutenu en rotation dans un orifice correspondant 19a pratiqué sur la cage 18a, respectivement dans un orifice 17a pratiqué sur la surface intérieure du support tubulaire 10. Il en est de même pour les volets inférieurs 6b,8b qui comportent chacun deux axes de pivotement 22a,22b supportés en rotation par des orifices 19b, 17b.Each upper flap 6a, 8a has two projections forming pivot axes 22a, 23a respectively located at the ends of the flap so that each axis is supported in rotation in a corresponding orifice 19a made on the cage 18a, respectively in an orifice 17a made on the inner surface of the tubular support 10. It is the same for the lower flaps 6b, 8b which each have two pivot axes 22a, 22b rotatably supported by holes 19b, 17b.
En plus des deux saillies de pivotement, chaque volet supérieur 6a, 8a présente sur un côté un ergot de guidage 20a, 21 a dans une rainure inclinée 24a,25a réalisée sur la surface intérieure du corps de buse 12. Le déplacement de l'ergot 20a,21a dans la rainure correspondante 24a,25a commande le pivotement de chaque volet 6a, 6b. De la même manière, les volets inférieurs 6b,8b pivotent autour de leurs axes respectifs lors du déplacement des ergots de guidage 20b,21b dans des rainures inclinées correspondantes 24b,25b pratiquées dans la surface intérieure du corps de buse 12.In addition to the two pivoting projections, each upper flap 6a, 8a has on one side a guide pin 20a, 21a in an inclined groove 24a, 25a produced on the inner surface of the nozzle body 12. The movement of the pin 20a, 21a in the corresponding groove 24a, 25a controls the pivoting of each flap 6a, 6b. In the same way, the lower flaps 6b, 8b pivot around their respective axes during the displacement of the guide pins 20b, 21b in corresponding inclined grooves 24b, 25b formed in the inner surface of the nozzle body 12.
Tel que visible à la figure 2, le dispositif 3 comporte également une buse tubulaire allongée 7 réalisée en une seule pièce avec un corps de buse annulaire 12. La buse 7 est reliée au corps 12 par des pattes 13 qui sont prévues pour glisser dans les fentes 16 du support tubulaire 10 et assurer ainsi le guidage en translation du corps de buse 12.As shown in Figure 2, the device 3 also includes an elongated tubular nozzle 7 made in one piece with an annular nozzle body 12. The nozzle 7 is connected to the body 12 by lugs 13 which are provided to slide in the slots 16 of the tubular support 10 and thus ensure the translational guidance of the nozzle body 12.
Le corps de buse 12 présente sur sa surface intérieure, dans deux zones diamétralement opposées, des canaux ou rainures 24a, 25a inclinées dans un sens dans la partie supérieure de cette surface, respectivement 24b,25b inclinées dans le sens contraire dans la partie inférieure de cette dernière. Les rainures 24,25 forment un certain angle avec l'axe longitudinal du dispositif. La valeur de l'angle d'inclinaison, ainsi que la longueur de chaque rainure sont calculées pour permettre le pivotement complet de chaque volet entre une position d'ouverture maximale et une position de fermeture maximale, tel qu'il sera expliqué plus loin.The nozzle body 12 has on its inner surface, in two diametrically opposite zones, channels or grooves 24a, 25a inclined in one direction in the upper part of this surface, respectively 24b, 25b inclined in the opposite direction in the lower part of the latter. The grooves 24,25 form a certain angle with the longitudinal axis of the device. The value of the angle of inclination, as well as the length of each groove are calculated to allow the complete pivoting of each flap between a maximum open position and a maximum closed position, as will be explained below.
Le corps de buse 12 présente un ergot 27 sur sa surface extérieure, ergot qui est prévu pour s'engager dans une rainure hélicoïdale 30 pratiquée sur la surface intérieure d'une bague de commande périphérique 28.The nozzle body 12 has a lug 27 on its outer surface, a lug which is designed to engage in a helical groove 30 formed on the inner surface of a peripheral control ring 28.
Le coulissement du corps de buse 12 est commandé par une bague de commande 28 qui entoure le corps tubulaire 10 et le corps de buse 12. Elle comporte à cet effet une rainure hélicoïdale 30 sur sa surface intérieure dans laquelle s'engage l'ergot 27 du corps de buse 12. Une collerette interne 31 de la bague 28 empêche la bague de se déplacer vers l'avant car elle butte contre le rebord 15 du support tubulaire 10. Ainsi, la bague 28 est empêchée de se déplacer en translation axiale, mais elle peut tourner autour de l'axe longitudinal du dispositif 3, qui se trouve en prolongation de l'axe longitudinal du sèche-cheveux.The sliding of the nozzle body 12 is controlled by a control ring 28 which surrounds the tubular body 10 and the nozzle body 12. It therefore has a helical groove 30 on its inner surface in which engages the lug 27 of the nozzle body 12. An internal flange 31 of the ring 28 prevents the ring from moving forward because it abuts against the rim 15 of the tubular support 10. Thus, the ring 28 is prevented from moving in axial translation, but it can rotate around the longitudinal axis of the device 3, which is an extension of the longitudinal axis of the hair dryer.
Les diverses pièces constitutives du dispositif 3 peuvent être exécutées, par exemple en une matière plastique, par une technique d'injection, les pièces en mouvement pouvant avantageusement être réalisées en un matériau plastique du type POM, ou en une matière plastique chargée en bisulfure de molybdène, ou tout autre matériau ayant de bonnes propriétés antifriction. A titre de variante, les frottements peuvent être réduits par lubrification des pièces en mouvement ou de leurs guidages, en utilisant une graisse ou un film d'huile.The various constituent parts of the device 3 can be executed, for example in a plastic material, by an injection technique, the moving parts can advantageously be made in a plastic material of the POM type, or in a plastic material loaded with bisulphide. molybdenum, or any other material with good anti-friction properties. Alternatively, friction can be reduced by lubricating the moving parts or their guides, using a grease or an oil film.
En fonctionnement, en faisant tourner la bague de commande 28 autour de son axe, on commande le déplacement en translation axiale du corps de buse 12 avec la buse 7 par action de la rainure 30 sur l'ergot 27. L'amplitude du mouvement de la buse 7 est délimitée, d'une part par le rebord 15 du support tubulaire 10 et, d'autre part, par le rebord arrière 32 de la bague de commande 28. Le déplacement en translation du corps de buse 12 commande à son tour le pivotement des volets supérieurs 6a, 8a dans un sens et, en même temps, des volets inférieurs 6b,8b dans le sens contraire.In operation, by rotating the control ring 28 about its axis, the displacement in axial translation of the nozzle body 12 is controlled with the nozzle 7 by action of the groove 30 on the lug 27. The amplitude of the movement of the nozzle 7 is delimited, on the one hand by the rim 15 of the tubular support 10 and, on the other hand, by the rear rim 32 of the control ring 28. The translational movement of the nozzle body 12 in turn controls the pivoting of the upper flaps 6a, 8a in one direction and, at the same time, the lower flaps 6b, 8b in the opposite direction.
Les figures 4 et 5 illustrent le dispositif 3 dans deux positions extrêmes de fonctionnement. Dans la position de la figure 4, la buse 7 se trouve complètement à l'intérieur du corps support 10 du dispositif 3 et les volets supérieurs 6a,8a et inférieurs 6b, 8b sont orientés vers la périphérie du support 10, en leur position d'écartement maximum par rapport à la buse 7. Dans cette position, le flux d'air soufflé par l'appareil, guidé par les parois recourbées des volets et par les parois rectilignes de la buse, suit les directions indiquées par les flèches de la figure 4, il s'agit d'un flux diffus à plusieurs directions. La valeur de la surface de la section libre de sortie d'air est dans ce cas maximale.Figures 4 and 5 illustrate the device 3 in two extreme operating positions. In the position of Figure 4, the nozzle 7 is completely inside the support body 10 of the device 3 and the upper flaps 6a, 8a and lower 6b, 8b are oriented towards the periphery of the support 10, in their position of maximum spacing relative to the nozzle 7. In this position, the air flow blown by the device, guided by the curved walls of the flaps and by the straight walls of the nozzle, follows the directions indicated by the arrows in Figure 4, it is a diffuse flow in several directions. The value of the area of the free air outlet section is in this case maximum.
Pour arriver dans la position représentée à la figure 5, on a fait tourner au maximum la bague de commande 28, ce qui fait que la buse 7 est en position complètement sortie par rapport à l'extrémité avant du support 10 et les volets sont rabattus de manière à obturer complètement l'espace existant entre le support 10 et la buse 7. Dans cette position, l'air soufflé par l'appareil sort uniquement par partie centrale via la buse 7 en suivant la flèche indiquée sur la figure 5. Le flux d'air obtenu dans ce cas est un flux d'air concentré, de direction axiale. La valeur de la surface libre de sortie d'air atteint ici sa position limite inférieure, cette valeur étant voisine à celle de la section de la buse 7.To reach the position shown in FIG. 5, the control ring 28 has been turned as much as possible, so that the nozzle 7 is in the fully extended position relative to the front end of the support 10 and the flaps are folded down. so as to completely close off the space existing between the support 10 and the nozzle 7. In this position, the air blown by the device exits only through the central part via the nozzle 7 by following the arrow indicated in FIG. 5. The air flow obtained in this case is a concentrated air flow, of axial direction. The value of the free air outlet surface here reaches its lower limit position, this value being close to that of the section of the nozzle 7.
La valeur de la section de sortie d'air et, par conséquent, l'intensité du flux d'air peut être variée de manière continue, en faisant tourner dans un sens ou dans l'autre la bague de commande 28. Ainsi, elle peut prendre toute position intermédiaire entre les deux positions extrêmes représentées aux figures 4 et 5.The value of the air outlet section and, consequently, the intensity of the air flow can be varied continuously, by turning the control ring 28 in one direction or the other. can take any intermediate position between the two extreme positions shown in Figures 4 and 5.
D'autres variantes de l'invention peuvent être envisagées sans sortir du cadre de ses revendications.Other variants of the invention can be envisaged without departing from the scope of its claims.
Ainsi, l'angle d'inclinaison des deux volets supérieurs 6a, 8a peut être identique pour les deux volets, ou différent pour chacun d'entre eux. Par conséquent, les deux volets peuvent effectuer un mouvement de rotation de même amplitude ou d'amplitudes différentes.Thus, the angle of inclination of the two upper flaps 6a, 8a can be identical for the two flaps, or different for each of them. Consequently, the two flaps can perform a rotational movement of the same amplitude or of different amplitudes.
De la même manière, le nombre de volets à utiliser n'est pas limité à deux, on peut en utiliser plusieurs de chaque côté de la buse, sachant que la capacité d'obturation des volets augmente avec leur nombre, mais également la complexité du mécanisme de commande. Il est également évident qu'on peut utiliser tout autre mécanisme de commande en déplacement axial de la buse, notamment on peut envisager d'utiliser un mécanisme du type pignon et crémaillère, du type roue dentée et vis sans fin, ou tout autre type de mécanisme capable de transformer un mouvement rotatif de la bague de commande périphérique en un mouvement de translation axiale de la buse centrale. Une commande motorisée pour l'actionnement d'un tel mécanisme pourrait également être envisagée. In the same way, the number of flaps to be used is not limited to two, one can use several on each side of the nozzle, knowing that the shutter capacity of flaps increases with their number, but also the complexity of the control mechanism. It is also obvious that any other mechanism for controlling the axial displacement of the nozzle can be used, in particular one can envisage using a mechanism of the pinion and rack type, of the toothed wheel and worm type, or any other type of mechanism capable of transforming a rotary movement of the peripheral control ring into an axial translation movement of the central nozzle. Motorized control for actuating such a mechanism could also be envisaged.
