  • un manche allongé par lequel ledit appareil est destiné à être tenu manuellement pour être utilisé, ledit manche s'étendant longitudinalement entre une première et une deuxième extrémité selon une direction moyenne d'extension longitudinale,
  • une tête de soufflage qui prolonge ledit manche à partir de ladite première extrémité et qui est pourvue d'une sortie d'air par laquelle un flux d'air est destiné à être soufflé vers l'extérieur selon une direction moyenne de soufflage,
  • un module de moto-ventilation pour générer ledit flux d'air,
  • et un élément chauffant électrique pour chauffer ledit flux d'air.
The invention relates more specifically to a portable hairdressing device comprising:
  • an elongated handle by which said apparatus is intended to be held manually for use, said handle extending longitudinally between a first and a second end in a mean direction of longitudinal extension,

L'appareil de coiffure 1 conforme à l'invention est conçu pour être saisi et manipulé à la main. Il s'agit donc d'un appareil de coiffure portatif, manuel, de préférence destiné à une utilisation dans un cadre domestique par un utilisateur dépourvu de compétences professionnelles particulières en matière de coiffure. Préférentiellement, l'appareil de coiffure 1 est conçu pour que l'utilisateur utilise l'appareil 1 sur lui-même, c'est-à-dire sur ses propres cheveux. Toutefois, il est parfaitement envisageable que l'appareil 1 soit conçu pour une utilisation par l'utilisateur sur les cheveux d'une tierce personne, sans sortir du cadre de l'invention.The hairdressing appliance 1 according to the invention is designed to be gripped and manipulated by hand. It is therefore a portable, manual hairdressing device, preferably intended for use in a domestic setting by a user lacking particular professional hairdressing skills. Preferably, the hairdressing appliance 1 is designed so that the user uses the appliance 1 on himself, that is to say on his own hair. However, it is perfectly possible for the device 1 to be designed for use by the user on the hair of a third person, without departing from the scope of the invention.

De préférence, et conformément au mode de réalisation illustré aux figures, l'appareil de coiffure 1 forme un sèche-cheveux (ou séchoir à cheveux), qui permet à un utilisateur de sécher ses cheveux mouillés ou humides par soufflage en direction des cheveux d'un flux d'air forcé, chaud ou frais, et de faciliter une mise en forme des cheveux. L'invention n'est toutefois pas limitée à ce mode de réalisation spécifique et il est par exemple tout à fait envisageable que l'appareil de coiffure 1 forme par exemple une brosse à cheveux soufflante, ou tout autre appareil de coiffure portatif doté d'une fonction impliquant le soufflage d'un flux d'air sur les cheveux de l'utilisateur, et qui pourrait être plus spécifiquement utilisé à des fins de coiffage, par exemple en contact direct avec les cheveux (brossage, lissage, etc.). Par souci de concision, la description qui suit sera néanmoins essentiellement centrée sur un appareil de coiffure 1 de type sèche-cheveux comme illustré aux figures.Preferably, and in accordance with the embodiment illustrated in the figures, the hairdressing appliance 1 forms a hair dryer (or hair dryer), which allows a user to dry his wet or damp hair by blowing in the direction of the hair. 'a forced air flow, hot or cool, and to facilitate shaping of the hair. The invention is however not limited to this specific embodiment and it is, for example, quite conceivable that the hairdressing appliance 1 forms, for example, a blowing hairbrush, or any other portable hairdressing appliance provided with a function involving the blowing of an air flow onto the user's hair, and which could be more specifically used for styling purposes, for example in direct contact with the hair (brushing, straightening, etc.). For the sake of brevity, the description which follows will nevertheless focus essentially on a hairdressing appliance 1 of the hair dryer type as illustrated in the figures.

L'appareil de coiffure 1 conforme à l'invention comprend un manche 2 (ou poignée) par lequel l'appareil 1 est destiné à être tenu manuellement pour être utilisé. Le manche 2 forme ainsi un organe de préhension manuelle, destiné à être saisi par l'utilisateur pour manipuler l'appareil de coiffure 1. Le manche 2 est allongé, c'est-à-dire qu'il s'étend majoritairement selon une seule direction de l'espace, correspondant à la direction longitudinale. En d'autres termes, le manche 2 présente une forme élancée, longiligne, de manière à pouvoir être saisi à pleine main par un utilisateur adulte. Le manche 2 s'étend longitudinalement entre une première extrémité 2A et une deuxième extrémité 2B selon une direction moyenne d'extension longitudinale X-X'. De préférence, la distance séparant lesdites première et deuxième extrémités 2A, 2B, correspondant à la longueur dudit manche 2, est suffisante pour permettre à tous les doigts d'une main d'un utilisateur de se refermer sur le manche 2. Le manche 2 est avantageusement formé d'une pièce, ou d'un assemblage de pièces. Il est par exemple de forme globalement tubulaire (avec par exemple une section moyenne circulaire ou elliptique, constante ou non), et est conformé et dimensionné pour assurer une bonne prise en main par utilisateur, en particulier une prise "à pleine main" c'est à dire par la paume et les doigts de la main. L'appareil de coiffure 1 comprend également une tête de soufflage 3 conçue pour générer un flux d'air (forcé) destiné à assurer une fonction de séchage des cheveux. La tête de soufflage 3 prolonge le manche 2 à partir de la première extrémité 2A et est pourvue d'une sortie d'air 4 par laquelle un flux d'air est destiné à être soufflé vers l'extérieur selon une direction moyenne de soufflage Y-Y', pour pouvoir être projeté en direction des cheveux de l'utilisateur, afin de les sécher. Formant avantageusement un sous-ensemble unitaire, la tête de soufflage 3 est de préférence fixe relativement au manche 2, et est préférentiellement solidaire dudit manche 2 de façon permanente, lesdits manche 2 et tête de soufflage 3 étant ainsi avantageusement indissociables.The hairdressing appliance 1 according to the invention comprises a handle 2 (or handle) by which the appliance 1 is intended to be held manually in order to be used. The handle 2 thus forms a manual gripping member, intended to be gripped by the user in order to manipulate the hairdressing appliance 1. The handle 2 is elongated, that is to say that it extends predominantly along a only direction of space, corresponding to the longitudinal direction. In other words, the handle 2 has a slender, elongated shape, so that it can be grasped with the full hand by an adult user. The handle 2 extends longitudinally between a first end 2A and a second end 2B in a mean direction of longitudinal extension X-X '. Preferably, the distance separating said first and second ends 2A, 2B, corresponding to the length of said handle 2, is sufficient to allow all the fingers of a hand of a user to close on the handle 2. The handle 2 is advantageously formed in one piece, or an assembly of parts. It is for example of generally tubular shape (with for example a circular or elliptical mean section, constant or not), and is shaped and dimensioned to ensure a good grip by the user, in particular a “ full hand ” grip. is to say by the palm and the fingers of the hand. The hairdressing appliance 1 also comprises a blowing head 3 designed to generate a (forced) air flow intended to perform a hair drying function. The blowing head 3 extends the handle 2 from the first end 2A and is provided with an air outlet 4 through which an air flow is intended to be blown outwards in an average blowing direction Y -Y ', to be able to be projected in the direction of the user's hair, in order to dry them. Advantageously forming a unitary sub-assembly, the blowing head 3 is preferably fixed relative to the handle 2, and is preferably secured to said handle 2 in a permanent manner, said sleeve 2 and blowing head 3 thus being advantageously inseparable.

La sortie d'air 4 présente une ouverture de forme générale sensiblement circulaire, comme illustré aux figures, et est par exemple pourvu d'une grille de protection. Préférentiellement, comme illustrée par les différentes figures, la sortie d'air 4 présente une section de soufflage en forme de disque. L'invention n'est toutefois pas limitée à une conformation géométrique particulière de la sortie d'air 4, qui peut présenter toute forme appropriée, par exemple une forme oblongue, une forme de fente, etc. The air outlet 4 has an opening of generally substantially circular shape, as illustrated in the figures, and is for example provided with a protective grid. Preferably, as illustrated by the various figures, the air outlet 4 has a disc-shaped blowing section. The invention is not however limited to a particular geometric conformation of the air outlet 4, which may have any suitable shape, for example an oblong shape, a slit shape, etc.

Il est envisageable que la sortie d'air 4 soit attachée de manière amovible à la tête de soufflage 3 (par exemple par encliquetage, vissage, emmanchement à force, verrouillage à baïonnette...). Il est toutefois avantageux et préféré que la tête de soufflage 3 forme avec la sortie d'air 4 un ensemble monobloc, qui n'est pas destiné à être désassemblé par utilisateur, ce qui facilite l'utilisation de l'appareil de coiffure 1 et évite à l'utilisateur d'égarer des accessoires.It is conceivable that the air outlet 4 is removably attached to the blowing head 3 (for example by snapping, screwing, press-fit, bayonet locking, etc.). However, it is advantageous and preferred that the blowing head 3 forms with the air outlet 4 a one-piece assembly, which is not intended to be disassembled by the user, which facilitates the use of the hairdressing appliance 1 and prevents the user from losing accessories.

Comme illustré aux figures, la direction moyenne d'extension longitudinale X-X' du manche 2 est avantageusement sensiblement perpendiculaire à la direction moyenne de soufflage Y-Y'. L'invention n'est toutefois pas limitée à ce mode de réalisation spécifique, qui s'avère particulièrement pratique pour l'utilisateur et permet de conférer un caractère compact à l'appareil de coiffure 1.As illustrated in the figures, the mean direction of longitudinal extension XX 'of the handle 2 is advantageously substantially perpendicular to the mean direction of blowing Y-Y'. The invention is not however limited to this specific embodiment, which proves to be particularly practical for the user and makes it possible to confer a compact nature on the hairdressing appliance 1.

Alternativement, lesdites directions moyennes d'extension longitudinale X-X' et de soufflage Y-Y' peuvent être inclinées l'une par rapport à l'autre, de sorte que l'angle entre lesdites directions moyennes d'extension longitudinale X-X' et de soufflage Y-Y' soit supérieur, ou inférieur, à 90°. Par exemple, l'angle entre lesdites directions moyennes d'extension longitudinale X-X' et de soufflage Y-Y' est avantageusement compris entre 80° et 100°, de façon préférentielle entre 85° et 95°.Alternatively, said mean directions of longitudinal extension XX 'and of blowing YY' can be inclined with respect to each other, so that the angle between said mean directions of longitudinal extension XX 'and of blowing YY' either greater than or less than 90 °. For example, the angle between said mean directions of longitudinal extension X-X 'and of blowing Y-Y' is advantageously between 80 ° and 100 °, preferably between 85 ° and 95 °.

L'appareil de coiffure 1 comprend par ailleurs un module de moto-ventilation 5 pour générer ledit flux d'air destiné à être soufflé vers l'extérieur par la tête de soufflage 3. Le module de moto-ventilation 5 prolonge le manche 2 à partir de la deuxième extrémité 2B, de sorte que le manche 2 est interposé entre le module de moto-ventilation 5 d'une part et la tête de soufflage 3 d'autre part, entre lesquels il s'étend longitudinalement. Ledit module de moto-ventilation 5 peut lui-même se prolonger par un cordon d'alimentation électrique 14, muni à son extrémité libre d'une fiche de connexion électrique. Le module de moto-ventilation 5 de l'appareil de coiffure 1 est donc préférentiellement déporté de la tête de soufflage 3 et du manche 2. Il est ainsi possible de dimensionner le module de moto-ventilation 5 de manière à générer un flux d'air d'un débit important, de façon économique, et sans pour autant impacter l'encombrement général de la tête de soufflage 3 et du manche 2. En outre, un tel agencement du module de moto-ventilation 5 permet avantageusement de mieux équilibrer le poids de l'appareil de coiffure 1, par une répartition des masses de part et d'autre du manche 2, ce qui contribue au confort d'usage de l'appareil 1 pour l'utilisateur. En effet, les masses sont ainsi réparties de part et d'autre de sa main ce qui facilite notamment ses mouvements lorsqu'il souhaite réaliser des opérations de coiffure (brushing, etc.).The hairdressing appliance 1 furthermore comprises a motor-ventilation module 5 for generating said air flow intended to be blown outwards by the blower head 3. The motor-ventilation module 5 extends the handle 2 to from the second end 2B, so that the handle 2 is interposed between the motorized ventilation module 5 on the one hand and the blowing head 3 on the other hand, between which it extends longitudinally. Said motor-ventilation module 5 can itself be extended by an electrical supply cord 14, provided at its free end with an electrical connection plug. The motorized ventilation module 5 of the hairdressing appliance 1 is therefore preferably offset from the blowing head 3 and from the handle 2. It is thus possible to size the motorized ventilation module 5 so as to generate a flow of air with a high flow rate, economically, and without impacting the overall size of the blowing head 3 and of the handle 2. In addition, such an arrangement of the motor-ventilation module 5 advantageously makes it possible to better balance the air. weight of the hairdressing appliance 1, by a distribution of the masses on either side of the handle 2, which contributes to the comfort of use of the appliance 1 for the user. Indeed, the masses are thus distributed on either side of his hand which in particular facilitates his movements when he wishes to carry out hairstyling operations (brushing, etc. ).

Le module de moto-ventilation 5 inclut une roue de ventilation 6 montée à rotation selon un axe de rotation Z-Z'. Le module de moto-ventilation 5 comprend également avantageusement un boîtier 7 au sein duquel est logée la roue de ventilation 6. La roue de ventilation 6 inclut avantageusement une série d'aubes disposées à la périphérie de la roue 6, de sorte que la rotation de la roue de ventilation 6 selon l'axe de rotation Z-Z' entraîne la création d'un flux d'air grâce auxdites aubes de la roue 6. De façon préférentielle, le module de moto-ventilation 5 inclut un moteur électrique relié à la roue de ventilation 6 pour entraîner cette dernière en rotation selon l'axe de rotation Z-Z'. Le moteur électrique est avantageusement disposé de manière adjacente à la roue de ventilation 6, et est par exemple pourvu d'un rotor qui entraîne en rotation un arbre moteur 10 relié, directement ou par l'intermédiaire d'un dispositif de transmission, à la roue de ventilation 6. Avantageusement, le rotor du moteur électrique tourne selon un axe moteur parallèle ou confondu à l'axe de rotation Z-Z' de la roue de ventilation 6. Cette configuration préférentielle permet une construction particulièrement compacte, robuste et fiable, privilégiant un entraînement direct de la roue de ventilation 6 par le moteur électrique, dont l'arbre moteur 10 est avantageusement directement solidaire d'un moyeu de la roue de ventilation 6.The motorized ventilation module 5 includes a ventilation wheel 6 mounted to rotate along an axis of rotation Z-Z '. The motorized ventilation module 5 also advantageously comprises a housing 7 within which the ventilation wheel 6 is housed. The ventilation wheel 6 advantageously includes a series of vanes arranged at the periphery of the wheel 6, so that the rotation of the ventilation wheel 6 along the axis of rotation ZZ 'causes the creation of an air flow thanks to said vanes of the wheel 6. Preferably, the module of motorized ventilation 5 includes an electric motor connected to the ventilation wheel 6 to drive the latter in rotation along the axis of rotation Z-Z '. The electric motor is advantageously arranged adjacent to the ventilation wheel 6, and is for example provided with a rotor which drives in rotation a motor shaft 10 connected, directly or by means of a transmission device, to the ventilation wheel 6. Advantageously, the rotor of the electric motor rotates along a motor axis parallel to or coincident with the axis of rotation ZZ 'of the ventilation wheel 6. This preferred configuration allows a particularly compact, robust and reliable construction, favoring a direct drive of the ventilation wheel 6 by the electric motor, the motor shaft 10 of which is advantageously directly secured to a hub of the ventilation wheel 6.

L'appareil de coiffure 1 comprend par ailleurs un élément chauffant électrique 8 pour chauffer ledit flux d'air généré par le module de moto-ventilation 5 et soufflé vers l'extérieur par la sortie d'air 4. L'élément chauffant électrique 8 peut être constitué par tout moyen de chauffage électrique adapté, reposant sur toute technologie permettant de transformer l'énergie électrique en énergie thermique. De préférence l'élément chauffant électrique 8 met en oeuvre un chauffage par effet Joule, étant entendu que l'invention n'est pas limitée à une technologie de chauffage particulière, pour autant que l'élément chauffant 8 soit intégré dans l'appareil de coiffure 1 et alimenté électriquement. L'élément chauffant électrique 8 présente par exemple une puissance supérieure à 500 W, et de façon encore plus préférentielle une puissance au moins égale à 1 000 W, et de préférence au moins égale à 1 500 W. Par exemple, l'élément chauffant électrique 8 comprend au moins une résistance électrique chauffante formée d'un enroulement de fils conducteurs métalliques (par exemple en nichrome) autour d'une âme isolante (par exemple en mica), laquelle présente par exemple une section cruciforme. Comme illustré aux figures, l'élément chauffant électrique 8 est embarqué à demeure au sein de la tête de soufflage 3, en amont de ladite sortie d'air 4 par rapport au flux d'air, de manière à pouvoir ainsi chauffer le flux d'air avant qu'il ne s'échappe hors de la tête de soufflage 3 par la sortie d'air 4. En d'autres termes, l'élément chauffant électrique 8 est incorporé de manière permanente dans la tête de soufflage 3 et n'est pas destiné à être dissocié de cette dernière.The hairdressing appliance 1 furthermore comprises an electric heating element 8 for heating said air flow generated by the motorized ventilation module 5 and blown outwards through the air outlet 4. The electric heating element 8 can be formed by any suitable electric heating means, based on any technology making it possible to transform electrical energy into thermal energy. Preferably, the electric heating element 8 implements heating by the Joule effect, it being understood that the invention is not limited to a particular heating technology, provided that the heating element 8 is integrated into the heating device. hairdresser 1 and electrically powered. The electric heating element 8 has for example a power greater than 500 W, and even more preferably a power at least equal to 1000 W, and preferably at least equal to 1500 W. For example, the heating element electric 8 comprises at least one electric heating resistor formed by a winding of metallic conductive wires (for example in nichrome) around an insulating core (for example in mica), which for example has a cruciform section. As illustrated in the figures, the electric heating element 8 is permanently embedded within the blowing head 3, upstream of said air outlet 4 with respect to the air flow, so as to be able to heat the flow of air. air before it escapes out of the blower head 3 through the air outlet 4. In other words, the electric heating element 8 is permanently incorporated in the blower head 3 and n 'is not intended to be dissociated from the latter.

Grâce au positionnement spécifique relativement au manche 2 de la tête de soufflage 3, de l'élément chauffant électrique 8 et du module de moto-ventilation 5, une distribution des masses tout à fait avantageuse est obtenue, qui permet de conférer à l'appareil de coiffure 1 un caractère particulièrement équilibré, propre à en faciliter le maniement.Thanks to the specific positioning relative to the handle 2 of the blowing head 3, of the electric heating element 8 and of the motor-ventilation module 5, a very advantageous mass distribution is obtained, which makes it possible to give the device of hairstyle 1 a particularly balanced character, suitable for facilitating handling.

En outre, l'axe de rotation Z-Z' d'une part s'inscrit dans un premier plan P1 sensiblement perpendiculaire à la direction moyenne de soufflage Y-Y', et d'autre part s'inscrit également dans un deuxième plan P2 sensiblement perpendiculaire à la direction moyenne d'extension longitudinale X-X'. En d'autres termes, l'axe de rotation Z-Z' de la roue de ventilation 6 est sensiblement perpendiculaire à un troisième plan P3 dans lequel s'inscrivent à la fois la direction moyenne de soufflage Y-Y' et la direction moyenne d'extension longitudinale X-X'. Dans le mode de réalisation illustré aux figures, les premier, deuxième et troisième plans P1, P2, P3 sont orthogonaux les uns par rapport aux autres. Il est cependant parfaitement envisageable que les premier et deuxième plans P1, P2 ne soient par exemple pas orthogonaux entre eux, dans le cas éventuel où la direction moyenne d'extension longitudinale X-X' n'est pas perpendiculaire à la direction moyenne de soufflage Y-Y' (cas où le manche 2 est par exemple incliné vers l'avant ou vers l'arrière par rapport au sens de sortie du flux d'air par la sortie d'air 4).In addition, the axis of rotation ZZ 'on the one hand is inscribed in a first plane P1 substantially perpendicular to the mean direction of blowing Y-Y', and on the other hand is also inscribed in a second plane P2 substantially perpendicular to the mean direction of longitudinal extension X-X '. In other words, the axis of rotation ZZ 'of the ventilation wheel 6 is substantially perpendicular to a third plane P3 in which both the mean direction of blowing YY' and the mean direction of longitudinal extension fit. X-X '. In the embodiment illustrated in the figures, the first, second and third planes P1, P2, P3 are orthogonal to each other. It is however perfectly conceivable that the first and second planes P1, P2 are for example not orthogonal to each other, in the possible case where the mean direction of longitudinal extension XX 'is not perpendicular to the mean direction of blowing YY' (case where the handle 2 is for example inclined forward or backward with respect to the direction of exit of the air flow through the air outlet 4).

Grâce à l'orientation particulière de l'axe de rotation Z-Z' susvisée, d'éventuels effets gyroscopiques indésirables sont minimisés, sinon éliminés, ce qui conduit à un confort d'utilisation accrue, notamment lorsque l'utilisateur effectue un séchage de type «brushing». En effet, lors de la réalisation d'une mise en plis de type «brushing», l'utilisateur effectue généralement des mouvements répétés de balancement du poignet pour balayer chaque mèche à coiffer avec le flux d'air émis par l'appareil de coiffure 1. Ce mouvement de balancier est susceptible d'être particulièrement inconfortable lorsque surviennent des effets gyroscopiques parasites dus à la rotation de la roue de ventilation 6 et/ou d'autres éléments tournants du module de moto-ventilation 5 (par exemple le rotor du moteur électrique d'entraînement de la roue 6). L'invention permet de pallier à cet inconvénient, en limitant et/ou compensant les effets gyroscopiques intempestifs grâce à un positionnement spécifique de l'axe de rotation Z-Z', perpendiculaire au troisième plan P3 comme exposé ci-avant. En particulier, grâce à cette orientation spécifique de l'axe de rotation Z-Z' par rapport à la fois à la direction de soufflage Y-Y' et à la direction d'extension longitudinale X-X' du manche 2, d'éventuels effets de déséquilibre dynamique par effets gyroscopiques sont minimisés, ce qui permet à l'utilisateur d'effectuer des mouvements de balancement du poignet de manière confortable lors de l'opération de « brushing ». En outre, grâce à cette position tout à fait remarquable de l'axe de rotation Z-Z', la sensation désagréable d'instabilité qui pouvait exister dans les appareils de l'art antérieur lors du démarrage de l'appareil, liée à l'apparition brutale de l'effet gyroscopique du moteur, est remarquablement réduite, voire supprimée, contribuant ainsi au confort d'utilisation et à la sécurité de l'utilisateur. De plus, grâce à l'orientation particulière de l'axe de rotation Z-Z' susvisée par rapport à la direction moyenne de soufflage Y-Y', une meilleure répartition de l'air sur l'ensemble de l'élément chauffant 8 peut être obtenue. En effet, compte tenu du sens de rotation de l'hélice, l'air viendra naturellement et facilement se concentrer sur la portion arrière du conduit intermédiaire 12. La trajectoire de l'air se trouve alors optimisée pour parcourir entièrement l'élément chauffant 8. Cela permet de mieux dissiper les calories fournies par l'élément chauffant 8 dans le flux d'air, optimisant ainsi l'échange thermique et donc la performance de l'appareil 1, en évitant ainsi en particulier la formation de points chauds qui pourraient détériorer l'élément chauffant 8.Thanks to the particular orientation of the aforementioned axis of rotation ZZ ', any undesirable gyroscopic effects are minimized, if not eliminated, which leads to increased comfort of use, in particular when the user performs drying of the "type". brushing ”. Indeed, when carrying out a styling of the " brushing " type, the user generally performs repeated movements of rocking of the wrist to sweep each lock to be styled with the air flow emitted by the styling device. 1. This pendulum movement is liable to be particularly uncomfortable when parasitic gyroscopic effects occur due to the rotation of the ventilation wheel 6 and / or other rotating elements of the motor-ventilation module 5 (for example the rotor of the ventilation unit 5). electric wheel drive motor 6). The invention makes it possible to overcome this drawback, by limiting and / or compensating for unwanted gyroscopic effects thanks to a specific positioning of the axis of rotation Z-Z ', perpendicular to the third plane P3 as explained above. In particular, thanks to this specific orientation of the axis of rotation ZZ 'with respect to both the blowing direction YY' and the direction of longitudinal extension XX 'of the handle 2, possible effects of dynamic imbalance by Gyroscopic effects are minimized, allowing the user to comfortably sway the wrist during the " brushing " operation. In addition, thanks to this quite remarkable position of the axis of rotation Z-Z ', the unpleasant feeling of instability which could exist in the devices of the prior art when starting the device, linked to the The sudden onset of the gyroscopic effect of the motor is remarkably reduced, or even eliminated, thus contributing to the comfort of use and the safety of the user. In addition, thanks to the particular orientation of the aforementioned axis of rotation ZZ 'with respect to the average blowing direction Y-Y', a better distribution of the air over the whole of the heating element 8 can be obtained. Indeed, taking into account the direction of rotation of the propeller, the air will come naturally and easily to concentrate on the rear portion of the intermediate duct 12. The trajectory of the air is then optimized to travel entirely through the heating element 8. This makes it possible to better dissipate the calories supplied by the heating element 8 in the air flow, thus optimizing the heat exchange and therefore the performance of the device 1, thus avoiding in particular the formation of hot spots which could damage the heating element 8.

De préférence, le moteur électrique qui entraîne en rotation la roue de ventilation 6 est un moteur à rotor externe. Un tel moteur à rotor externe présente un excellent rendement, avec la possibilité de produire un couple important à grande vitesse, ce qui permet d'obtenir des performances optimales mais conduit à la génération d'effets gyroscopiques significatifs que l'invention permet de compenser, grâce au positionnement spécifique de l'axe de rotation Z-Z' exposé précédemment. La conception de l'appareil de coiffure 1 selon l'invention permet ainsi d'obtenir un excellent compromis entre le niveau de performance d'une part et le confort d'utilisation d'autre part.Preferably, the electric motor which drives the ventilation wheel 6 in rotation is an external rotor motor. Such an external rotor motor has excellent efficiency, with the possibility of producing a large torque at high speed, which makes it possible to obtain optimum performance but leads to the generation of significant gyroscopic effects which the invention makes it possible to compensate, thanks to the specific positioning of the axis of rotation ZZ 'explained above. The design of the hairdressing appliance 1 according to the invention thus makes it possible to obtain an excellent compromise between the level of performance on the one hand and the comfort of use on the other hand.

De préférence, le moteur électrique d'entraînement de la roue de ventilation 6 est un moteur électrique sans balai (moteur dit « brushless » ou machine synchrone auto-pilotée à aimants permanents). Un tel moteur sans balai est généralement plus robuste et plus léger qu'un moteur électrique classique à balai. Moins bruyant et plus économe en énergie, il offre en outre une plus grande souplesse et une meilleure précision du réglage de sa vitesse de rotation. De façon encore plus préférentielle, le moteur électrique d'entraînement de la roue de ventilation 6 est un moteur sans balai à courant continu (BLDC) à rotor externe avec capteurs. Un tel moteur présente un excellent niveau de performance, tout en étant compact, fiable et robuste. Un tel moteur est certes susceptible de générer des effets gyroscopiques significatifs, mais ces derniers sont avantageusement compensés par le positionnement judicieux de l'axe de rotation Z-Z' décrit précédemment.Preferably, the electric motor for driving the ventilation wheel 6 is a brushless electric motor (so-called " brushless " motor or machine. self-piloted synchronous with permanent magnets). Such a brushless motor is generally more robust and lighter than a conventional brushed electric motor. Less noisy and more energy efficient, it also offers greater flexibility and better precision in adjusting its rotation speed. Even more preferably, the electric motor for driving the fan wheel 6 is a brushless direct current motor (BLDC) with an external rotor with sensors. Such an engine has an excellent level of performance, while being compact, reliable and robust. Such a motor is certainly capable of generating significant gyroscopic effects, but the latter are advantageously compensated by the judicious positioning of the axis of rotation ZZ 'described above.

Avantageusement, le module de moto-ventilation 5 comprend une ouïe d'aspiration d'air 9 ménagée à travers le boîtier 7, en amont de la roue de ventilation 6 par rapport au flux d'air, pour permettre à la roue de ventilation 6 d'aspirer de l'air extérieur parallèlement audit axe de rotation Z-Z'. L'ouïe d'aspiration d'air 9 forme ainsi une ouverture selon l'axe de rotation Z-Z' permettant l'introduction d'air extérieur à l'intérieur du boîtier 7 sous l'effet de l'aspiration générée par la roue de ventilation 6 en rotation. Cette orientation spécifique de l'ouïe d'aspiration d'air 9 s'avère particulièrement avantageuse car elle est différente de l'orientation de la sortie d'air 4. Cela permet de réduire le risque de voir des cheveux se trouver en regard de l'ouïe d'aspiration 9 pendant l'utilisation de l'appareil de coiffure 1, limitant ainsi le risque d'aspiration intempestive de cheveux. Cela permet également d'aspirer de l'air frais, limitant ainsi le risque de surchauffe de l'appareil. De préférence une grille de protection (visibles aux figures) est également avantageusement mise en oeuvre pour la sécurité de l'utilisateur.Advantageously, the motorized ventilation module 5 comprises an air suction inlet 9 formed through the housing 7, upstream of the ventilation wheel 6 with respect to the air flow, to allow the ventilation wheel 6 to suck outside air parallel to said axis of rotation Z-Z '. The air suction opening 9 thus forms an opening along the axis of rotation ZZ 'allowing the introduction of outside air inside the housing 7 under the effect of the suction generated by the control wheel. 6 rotating ventilation. This specific orientation of the air suction inlet 9 proves to be particularly advantageous because it is different from the orientation of the air outlet 4. This makes it possible to reduce the risk of seeing the hair lying opposite it. the suction hearing 9 during the use of the hairdressing appliance 1, thus limiting the risk of inadvertent suction of hair. This also allows fresh air to be drawn in, thus limiting the risk of the device overheating. Preferably a protective grid (visible in the figures) is also advantageously implemented for the safety of the user.

Avantageusement, la roue de ventilation 6 est une roue de ventilation centrifuge (comme illustré aux figures) ou hélico-centrifuge. Le recours à une roue de ventilation centrifuge ou hélico-centrifuge permet de positionner l'ouïe d'aspiration d'air 9 selon l'axe de rotation Z-Z', tout en bénéficiant de performances aérauliques tout à fait appréciables. La mise en œuvre d'un tel ventilateur hélico-centrifuge ou centrifuge peut permettre d'obtenir, à encombrement équivalent, une pression interne élevée avec un débit d'air sensiblement analogue à celui d'un ventilateur à hélice ou hélicoïde, mais avec une vitesse de rotation moindre et donc un bruit généré moins important. De manière préférée, comme illustré schématiquement aux figures, la roue de ventilation 6 est une roue de ventilation centrifuge, comprenant une pluralité d'aubes. Une telle roue de ventilation 6 centrifuge est d'encombrement relativement réduit et de fonctionnement relativement silencieux, ce qui s'avère fort appréciable pour un appareil destiné à être utilisé à proximité de la tête et des oreilles. L'invention n'est toutefois pas limitée à la mise en œuvre d'une roue de ventilation 6 centrifuge ou hélico-centrifuge, et il est par exemple envisageable de recourir à une roue de ventilation tangentielle, sans pour autant que l'on sorte du cadre de l'invention.Advantageously, the fan wheel 6 is a centrifugal fan wheel (as illustrated in the figures) or a helico-centrifugal fan wheel. The use of a centrifugal or helico-centrifugal fan wheel makes it possible to position the air suction louver 9 along the axis of rotation Z-Z ', while benefiting from quite appreciable aeraulic performance. The implementation of such a helico-centrifugal or centrifugal fan can make it possible to obtain, for an equivalent size, a high internal pressure with an air flow rate. substantially similar to that of a propeller or propeller fan, but with a lower rotation speed and therefore less noise generated. Preferably, as illustrated schematically in the figures, the fan wheel 6 is a centrifugal fan wheel, comprising a plurality of blades. Such a centrifugal fan wheel 6 is relatively small in size and operates relatively quietly, which proves to be very appreciable for a device intended to be used near the head and the ears. The invention is not, however, limited to the implementation of a centrifugal or helico-centrifugal fan wheel 6, and it is for example possible to use a tangential fan wheel, without however leaving within the scope of the invention.

Avantageusement, le module de moto-ventilation 5 inclut une volute 11 qui enveloppe la roue de ventilation 6 et permet, en coopération avec la roue de ventilation, de générer le flux d'air. La volute 11 forme ainsi une chambre de travail interne au sein de laquelle est logée la roue de ventilation 6. Cette chambre interne est pourvue d'une entrée d'air correspondant à l'ouïe d'aspiration 9, par laquelle l'air ambiant est aspiré axialement par la roue de ventilation 6 au sein de la chambre de travail formée par la volute 11. La chambre de travail en question est également pourvue d'une sortie d'air par laquelle l'air aspiré est refoulé radialement, par la roue ventilation 6, hors de la chambre de travail formée par la volute 11.Advantageously, the motorized ventilation module 5 includes a volute 11 which surrounds the ventilation wheel 6 and makes it possible, in cooperation with the ventilation wheel, to generate the air flow. The volute 11 thus forms an internal working chamber within which the ventilation wheel 6 is housed. This internal chamber is provided with an air inlet corresponding to the suction inlet 9, through which the ambient air is sucked axially by the ventilation wheel 6 within the working chamber formed by the volute 11. The working chamber in question is also provided with an air outlet through which the sucked air is discharged radially, by the ventilation wheel 6, outside the working chamber formed by the volute 11.

Avantageusement, l'appareil 1 comprend un conduit intermédiaire 12 ménagé au sein du manche 2 pour mettre en communication aéraulique la roue de ventilation 6 avec la tête de soufflage 3. Pour cela, le boîtier 7 du module de moto-ventilation 5, qui inclut ou forme la volute 11, communique avec ledit conduit intermédiaire 12. Cela signifie que la volute 11 débouche dans le conduit intermédiaire 12, de sorte à propulser dans le conduit intermédiaire 12 l'air aspiré à l'extérieur, via l'ouïe d'aspiration d'air 9, par la roue de ventilation 6. Avantageusement, la tête de soufflage 3 forme elle-même un conduit de soufflage 13 qui est relié d'une part au conduit intermédiaire 12 et d'autre part à ladite sortie d'air 4 par laquelle il débouche sur l'extérieur. L'élément chauffant électrique 8 est avantageusement disposé dans le conduit de soufflage 13, à l'amont de la sortie d'air 4 et à l'aval du conduit intermédiaire 12, en considération du sens du flux d'air. Ainsi, le conduit intermédiaire 12 canalise avantageusement le flux d'air à travers et à l'intérieur du manche 2, en l'espèce dans le sens de la deuxième extrémité 2B vers la première extrémité 2A, en direction de la tête de soufflage 3, selon une trajectoire qui est de préférence sensiblement rectiligne. La tête de soufflage s'étend avantageusement, selon ladite direction moyenne de soufflage Y-Y', entre une face arrière fermée 3A et une face avant 3B comprenant ladite sortie d'air 4. En d'autres termes, le conduit de soufflage 13 débouche uniquement au niveau de la face avant 3B mais ne communique pas avec l'extérieur au niveau de la face arrière 3A qui est fermée de manière étanche à l'air. Les performances aérauliques sont optimisées grâce à cette mesure technique, qui évite également la présence, au niveau de la tête de soufflage 3, d'une ouïe d'aspiration qui pourrait être source d'inconfort, voire de risque, pour l'utilisateur. La tête de soufflage 3 embarque avantageusement un déflecteur 15, conçu et configuré pour dévier le flux d'air provenant du conduit intermédiaire 12 et l'amener dans le conduit de soufflage 13. Ainsi le déflecteur 15 est avantageusement conformé et agencé pour faire subir au flux d'air provenant du conduit intermédiaire 12 une déflection d'au moins 70°, et de préférence d'environ 90°, en direction de la sortie d'air 4. Ce virage imparti par le déflecteur 15 au flux d'air permet de faire passer le flux d'air d'une trajectoire sensiblement parallèle à la direction moyenne d'extension longitudinale X-X' au sein du manche 2, à une trajectoire sensiblement parallèle à la direction moyenne de soufflage direct Y-Y' au sein du conduit de soufflage 13, jusque vers la sortie d'air 4.Advantageously, the device 1 comprises an intermediate duct 12 formed within the handle 2 to place the ventilation wheel 6 in aeraulic communication with the blower head 3. For this, the housing 7 of the motorized ventilation module 5, which includes or forms the volute 11, communicates with said intermediate duct 12. This means that the volute 11 opens into the intermediate duct 12, so as to propel into the intermediate duct 12 the air sucked in from the outside, via the outlet of air suction 9, by the ventilation wheel 6. Advantageously, the blowing head 3 itself forms a blowing duct 13 which is connected on the one hand to the intermediate duct 12 and on the other hand to said outlet of air 4 through which it opens to the outside. The electric heating element 8 is advantageously arranged in the blowing duct 13, upstream of the air outlet 4 and downstream of the intermediate duct 12, in consideration of the direction of air flow. Thus, the intermediate duct 12 advantageously channels the air flow through and inside the handle 2, in this case in the direction of the second end 2B towards the first end 2A, in the direction of the blowing head 3 , along a path which is preferably substantially rectilinear. The blowing head advantageously extends, along said mean blowing direction Y-Y ', between a closed rear face 3A and a front face 3B comprising said air outlet 4. In other words, the blowing duct 13 opens only at the level of the front face 3B but does not communicate with the outside at the level of the rear face 3A which is closed in an airtight manner. The aeraulic performance is optimized thanks to this technical measure, which also avoids the presence, at the level of the blowing head 3, of a suction opening which could be a source of discomfort, or even of risk, for the user. The blowing head 3 advantageously incorporates a deflector 15, designed and configured to deflect the air flow coming from the intermediate duct 12 and bring it into the blowing duct 13. Thus, the deflector 15 is advantageously shaped and arranged to subject the air to the air. air flow coming from the intermediate duct 12 a deflection of at least 70 °, and preferably about 90 °, in the direction of the air outlet 4. This bend imparted by the deflector 15 to the air flow allows to cause the air flow to pass from a path substantially parallel to the mean direction of longitudinal extension XX 'within the handle 2, to a path substantially parallel to the mean direction of direct blowing YY' within the blowing duct 13, up to the air outlet 4.

Avantageusement, l'appareil de coiffure comprend un module électronique 16 pour piloter et/ou contrôler le fonctionnement de l'appareil 1. Le module électronique 16 se présente par exemple sous la forme d'une carte électronique (PCBA) formé d'une plaque de circuit imprimé (PCB) sur laquelle sont montés différents composants électroniques (condensateur, résistance, transistors, etc.). La carte électronique formant le module électronique 16 est avantageusement relié fonctionnellement au module de moto-ventilation 5 et/ou à l'élément chauffant électrique 8, ainsi que de préférence à au moins un organe de réglage 17 du fonctionnement de l'appareil 1, organe de réglage 17 qui est actionnable manuellement par l'utilisateur. Le module électronique 16 est avantageusement embarqué au sein de la tête de soufflage 3, en amont dudit élément chauffant électrique 8 par rapport au flux d'air. De cette façon, le flux d'air en provenance du conduit intermédiaire 12 balaye en premier lieu le module électronique 16, ce qui permet de le refroidir, avant d'être ensuite chauffé, en aval, par l'élément chauffant électrique 8, pour enfin sortir à l'extérieur de l'appareil 1 par la sortie d'air 4. Cette configuration permet de loger le module électronique 16 à proximité immédiate de l'élément chauffant 8, sans que cela ne pose de problème de surchauffe du module électronique 16 qui est refroidi par le flux d'air auquel il est soumis avant l'élément chauffant électrique 8. Dans ce mode de réalisation particulièrement avantageux, l'appareil de coiffure 1 présente un caractère particulièrement compact et une construction particulièrement simple et fiable, qui permet un fonctionnement optimal grâce en particulier au rafraîchissement efficace du module électronique 16 obtenu par le positionnement spécifique de ce dernier dans le flux d'air. De préférence, le module électronique 16 est attaché au déflecteur 15, sur la face interne de ce dernier qui assume dès lors une double fonction de déflection du flux d'air et de support pour le module électronique 16. Le positionnement spécifique du module électronique 16 sur le déflecteur 15 permet d'optimiser le rafraîchissement du module électronique 16, en raison du fait qu'au niveau du déflecteur 15 le flux d'air est susceptible de subir des phénomènes de turbulence qui favorisent l'échange thermique.Advantageously, the hairdressing appliance comprises an electronic module 16 for controlling and / or controlling the operation of the appliance 1. The electronic module 16 is for example in the form of an electronic card (PCBA) formed of a plate. printed circuit board (PCB) on which various electronic components are mounted (capacitor, resistor, transistors, etc. ). The electronic card forming the electronic module 16 is advantageously operatively connected to the motorized ventilation module 5 and / or to the electric heating element 8, as well as preferably to at least one adjustment member 17 for the operation of the device 1, adjustment member 17 which can be operated manually by the user. The electronic module 16 is advantageously on board within the blowing head 3, upstream of said electric heating element 8 relative to the air flow. In this way, the air flow coming from the intermediate duct 12 first sweeps the electronic module 16, which allows it to be cooled, before being then heated, downstream, by the electric heating element 8, in order to finally exit outside the device 1 through the air outlet 4. This configuration allows the electronic module 16 to be housed in the immediate vicinity of the heating element 8, without causing any problem of overheating of the electronic module. 16 which is cooled by the air flow to which it is subjected before the electric heating element 8. In this particularly advantageous embodiment, the hairdressing appliance 1 has a particularly compact character and a particularly simple and reliable construction, which allows optimal operation, in particular thanks to the efficient cooling of the electronic module 16 obtained by the specific positioning of the latter in the air flow. Preferably, the electronic module 16 is attached to the deflector 15, on the internal face of the latter which therefore assumes a dual function of deflection of the air flow and of support for the electronic module 16. The specific positioning of the electronic module 16 on the deflector 15 makes it possible to optimize the cooling of the electronic module 16, due to the fact that at the level of the deflector 15 the air flow is liable to undergo turbulence phenomena which promote heat exchange.

Le conduit de soufflage formé par la tête de soufflage 3 présente avantageusement une forme sensiblement convergente en direction de la sortie d'air 4, afin de produire un effet de tuyère convergente qui permet de faire baisser la pression et d'augmenter la vitesse du flux d'air au niveau de la sortie 4. En d'autres termes, le conduit de soufflage 13 s'évase progressivement à partir de la face avant 3B en direction de la face arrière 3A. Cette forme évasée en direction de l'arrière permet également de dégager un espace suffisant pour loger le module électronique 16.The blowing duct formed by the blowing head 3 advantageously has a shape substantially converging in the direction of the air outlet 4, in order to produce a converging nozzle effect which makes it possible to lower the pressure and increase the speed of the flow. air at the outlet 4. In other words, the blowing duct 13 widens progressively from the front face 3B towards the rear face 3A. This flared shape towards the rear also makes it possible to free up sufficient space to house the electronic module 16.

Avantageusement, la tête de soufflage 3 embarque l'organe de réglage 17 du fonctionnement de l'appareil 1, lequel organe de réglage 17 est actionnable manuellement pour permettre un réglage du fonctionnement de l'appareil 1, par exemple un réglage de la puissance de soufflage et/ou de la température du flux d'air. De façon préférentielle, l'organe de réglage 17 est disposé sur la face arrière 3A de la tête de soufflage 3. Cette configuration, qui tire avantageusement parti du fait que la face arrière 3 est préférentiellement fermée, confère une excellente ergonomie à l'appareil de coiffure 1, en utilisant l'arrière de la tête de soufflage 3, habituellement dévolu à une fonction d'aspiration d'air dans les appareils de l'art antérieur, pour positionner un organe de réglage 17 que l'utilisateur peut dès lors actionner manuellement tout en séchant ses cheveux. En d'autres termes, l'organe de réglage 17 est avantageusement positionné pour qu'un utilisateur puisse enserrer le manche 2 d'une main tout en actionnant ledit premier organe de réglage 17 avec le pouce de ladite main. L'organe de réglage 17 en question est avantageusement conçu pour régler la vitesse du flux d'air, en assurant le réglage de la vitesse de rotation de la roue de ventilation 6, via le moteur électrique auquel cette dernière est reliée. Comme illustré, l'organe de réglage est avantageusement constitué d'une molette rotative tournant selon un axe correspondant avantageusement à la direction moyenne de soufflage Y-Y'. Le recours à une molette rotative, en particulier une molette configurée pour tourner selon un axe confondu ou parallèle à la direction moyenne de soufflage Y-Y', confère un caractère particulièrement ergonomique à l'appareil 1. De préférence, comme illustré aux figures, la molette est intégrée dans la tête de soufflage 3 de façon à ce qu'elle contribue elle-même à définir localement l'enveloppe superficielle de la tête de soufflage 3. Grâce à cette mesure technique, l'organe de réglage 17 affleure simplement l'enveloppe externe de la tête de soufflage 3, sans former de saillie notable à la surface de cette dernière. Cela permet non seulement de conférer un caractère esthétique à l'appareil 1, mais également de contribuer à sa compacité et à sa robustesse. De préférence, la molette se présente sous la forme d'au moins une bague ou portion de bague qui tourne selon l'axe de rotation précité autour d'un moyeu central fixe 20. Le moyeu central 20 en question se présente avantageusement sous la forme d'une paroi pleine, de forme sensiblement circulaire, qui contribue à délimiter la face arrière 3A. Comme exposé précédemment, la molette peut se présenter sous la forme d'une bague, et par exemple et comme illustré aux figures sous la forme d'une bague unitaire formée par une pièce unique d'un seul tenant de forme générale sensiblement circulaire. Il est toutefois envisageable que la molette se présente alternativement sous la forme d'une ou plusieurs portions de bague, par exemple par sous la forme de deux demi-bagues accolées de sorte à former ensemble un anneau. Dans ce dernier cas, une première demi-bague peut être par exemple dédiée au réglage du module de moto-ventilation 5, tandis que l'autre demi-bague peut être dédiée au réglage de l'élément chauffant 8, ou de tout autre élément fonctionnel. Avantageusement, la tête de soufflage 3 comprend une enveloppe extérieure incluant une portion en forme de coupelle qui forme ladite face arrière 3A, comme illustré aux figures. Ladite coupelle présente avantageusement un fond formé au moins en partie par le moyeu central 20, et une paroi latérale qui s'étend à partir de la périphérie dudit fond et est formée au moins en partie par la bague constituant avantageusement la molette. Dans ce mode de réalisation particulièrement avantageux qui correspond à celui illustré aux figures, la molette est parfaitement intégrée à la tête de soufflage 3, tout en étant aisément accessible et manipulable avec le pouce.Advantageously, the blowing head 3 carries the adjustment member 17 for the operation of the device 1, which adjustment member 17 can be actuated manually to allow adjustment of the operation of the device 1, for example an adjustment of the power of the device 1. blowing and / or temperature of the air flow. Preferably, the adjustment member 17 is arranged on the face rear 3A of the blowing head 3. This configuration, which advantageously takes advantage of the fact that the rear face 3 is preferably closed, gives excellent ergonomics to the hairdressing appliance 1, by using the rear of the blowing head 3 , usually assigned to an air suction function in devices of the prior art, to position an adjustment member 17 that the user can therefore manually actuate while drying his hair. In other words, the adjustment member 17 is advantageously positioned so that a user can grip the handle 2 with one hand while operating said first adjustment member 17 with the thumb of said hand. The adjustment member 17 in question is advantageously designed to adjust the speed of the air flow, by ensuring the adjustment of the speed of rotation of the ventilation wheel 6, via the electric motor to which the latter is connected. As illustrated, the adjustment member advantageously consists of a rotary wheel rotating along an axis advantageously corresponding to the mean blowing direction Y-Y ′. The use of a rotary wheel, in particular a wheel configured to rotate along an axis coincident with or parallel to the mean blowing direction Y-Y ', gives a particularly ergonomic character to the device 1. Preferably, as illustrated in the figures, the wheel is integrated into the blowing head 3 so that it itself contributes to locally defining the surface envelope of the blowing head 3. Thanks to this technical measure, the adjustment member 17 is simply flush with the 'outer casing of the blowing head 3, without forming a significant projection on the surface of the latter. This not only makes it possible to give an aesthetic character to the device 1, but also to contribute to its compactness and its robustness. Preferably, the wheel is in the form of at least one ring or ring portion which rotates along the aforementioned axis of rotation around a fixed central hub 20. The central hub 20 in question is advantageously in the form a solid wall, of substantially circular shape, which contributes to delimiting the rear face 3A. As explained above, the wheel can be in the form of a ring, and for example and as illustrated in the figures in the form of a unitary ring formed by a single piece in one piece of generally substantially circular shape. However, it is conceivable that the wheel is alternatively in the form of one or more portions of a ring, for example for example, in the form of two half-rings joined together so as to form a ring together. In the latter case, a first half-ring may for example be dedicated to adjusting the motor-ventilation module 5, while the other half-ring may be dedicated to adjusting the heating element 8, or any other element. functional. Advantageously, the blowing head 3 comprises an outer casing including a cup-shaped portion which forms said rear face 3A, as illustrated in the figures. Said cup advantageously has a bottom formed at least in part by the central hub 20, and a side wall which extends from the periphery of said bottom and is formed at least in part by the ring advantageously constituting the wheel. In this particularly advantageous embodiment which corresponds to that illustrated in the figures, the wheel is perfectly integrated into the blowing head 3, while being easily accessible and manipulated with the thumb.

L'appareil de coiffure 1 comporte également avantageusement un sélecteur air chaud / air frais 18, avantageusement monté sur le manche 2, par exemple à proximité de la première extrémité 2A de ce dernier, pour activer/désactiver l'élément chauffant électrique 8 et ainsi permettre à l'utilisateur de choisir entre souffler un flux d'air chaud ou un flux d'air à température ambiante. Le sélecteur air chaud/air frais 18 se présente par exemple sous la forme d'un interrupteur à bascule ou d'un bouton-poussoir. Ainsi, dans le mode de réalisation particulièrement avantageux illustré aux figures, l'utilisateur est en mesure d'une part de régler la vitesse du flux d'air en agissant sur la molette formant l'organe de réglage 17 disposé sur la face arrière 3A, et d'autre part de sélectionner un flux d'air chaud ou un flux d'air frais en agissant sur le sélecteur 18 disposé sur le manche 2, tout en procédant à l'opération de coiffure (par exemple de type « brushing ») sans avoir à interrompre celle-ci.The hairdressing appliance 1 also advantageously comprises a hot air / fresh air selector 18, advantageously mounted on the handle 2, for example near the first end 2A of the latter, to activate / deactivate the electric heating element 8 and thus allow the user to choose between blowing a hot air stream or a room temperature air stream. The hot air / fresh air selector 18 is for example in the form of a toggle switch or a push button. Thus, in the particularly advantageous embodiment illustrated in the figures, the user is able on the one hand to adjust the speed of the air flow by acting on the wheel forming the adjustment member 17 arranged on the rear face 3A. , and on the other hand to select a flow of hot air or a flow of cool air by acting on the selector 18 placed on the handle 2, while carrying out the styling operation (for example of the " brushing " type ) without having to interrupt it.

Avantageusement, lesdits tête de soufflage 3 et module de moto-ventilation 5 forment chacun, de chaque côté du manche 2, une excroissance respective qui s'étend selon au moins une direction transversale respective relativement à la direction moyenne d'extension longitudinale X-X' du manche 2. La présence de chacune des excroissances respectivement formées par la tête de soufflage 3 et le module de moto-ventilation 5 de part et d'autre du manche 2 permet de bien délimiter le manche 2 en formant de part et d'autre de ce dernier des gardes qui invitent de manière intuitive l'utilisateur à saisir l'appareil 1 au niveau du manche 2 uniquement, dans une configuration de préhension optimale. La présence de ces excroissances de part et d'autre du manche 2 contribue en outre à la bonne répartition des masses telle que mentionnée précédemment.Advantageously, said blowing head 3 and motorized ventilation module 5 each form, on each side of the handle 2, a respective protuberance which extends in at least one respective transverse direction relative to the mean direction of longitudinal extension XX 'of the handle 2. The presence of each of the protuberances respectively formed by the blowing head 3 and the motor-ventilation module 5 on either side of the handle 2 makes it possible to clearly delimit the handle 2 by forming guards on either side of the latter which intuitively invite the user to grasp the device 1 at the level of the handle 2 only, in an optimal gripping configuration. The presence of these protuberances on either side of the handle 2 further contributes to the good distribution of the masses as mentioned above.

L'excroissance formée par la tête de soufflage 3 s'étend ainsi selon au moins une direction transversale qui correspond à la direction moyenne de soufflage Y-Y'. L'excroissance formée par la tête de soufflage 3 n'est avantageusement pas centrée relativement au manche 2, et s'étend ainsi transversalement relativement à ce dernier de manière plus importante vers la face avant 3B que vers la face arrière 3A. En d'autres termes, la tête de soufflage 3 s'étend, selon la direction moyenne de soufflage Y-Y', d'une longueur L1 mesurée entre la direction moyenne d'extension longitudinale X-X' et la face avant 3B, et d'une longueur L2 mesurée entre la direction moyenne d'extension longitudinale X-X' et la face arrière 3A, la longueur L1 étant supérieure, et par exemple 1,2 à 1,8 fois supérieure, à la distance L2. Par exemple, L1=72 mm et L2=44 mm. De préférence, l'excroissance formée par la tête de soufflage 3 présente sensiblement une forme générale de révolution selon un axe correspondant la direction moyenne de soufflage Y-Y'.The protuberance formed by the blowing head 3 thus extends in at least one transverse direction which corresponds to the average blowing direction Y-Y '. The protuberance formed by the blowing head 3 is advantageously not centered relative to the handle 2, and thus extends transversely relative to the latter more significantly towards the front face 3B than towards the rear face 3A. In other words, the blowing head 3 extends, along the average blowing direction Y-Y ', by a length L1 measured between the average direction of longitudinal extension XX' and the front face 3B, and d 'a length L2 measured between the average direction of longitudinal extension XX' and the rear face 3A, the length L1 being greater, and for example 1.2 to 1.8 times greater, than the distance L2 . For example, L1 = 72 mm and L2 = 44 mm. Preferably, the protuberance formed by the blowing head 3 has substantially the general shape of revolution along an axis corresponding to the mean direction of blowing Y-Y '.

Quant à l'excroissance formée par le module de moto-ventilation 5, elle présente avantageusement une forme sensiblement cylindrique à base circulaire selon un axe correspondant à l'axe de rotation Z-Z'. L'excroissance formée par le module de moto-ventilation 5 s'étend avantageusement selon une hauteur H1 entre une première façade latérale habillée par la grille de protection et au niveau de laquelle est disposée l'ouïe d'aspiration d'air 9, et une deuxième façade latérale opposée 19. La deuxième façade latérale 19 est avantageusement fermée. Derrière elle est avantageusement disposé le moteur d'entraînement de la roue de ventilation 6, moteur qui est ainsi interposé entre la deuxième façade latérale 19 fermée (mais préférentiellement démontable pour accéder au moteur) et la roue de ventilation 6. De préférence, l'excroissance formée par la tête de soufflage 3 s'étend, parallèlement à la direction correspondant à l'axe de rotation Z-Z', selon une distance H2 qui est avantageusement supérieure ou égale à la distance d'extension H1 de l'excroissance formée par le module de moto-ventilation 5 selon cette même direction Z-Z'. Par exemple, H1=70 mm et H2=83 mm. Ceci permet de conférer un caractère particulièrement équilibré et compact à l'appareil 1, contribuant à rendre son usage facile et confortable. Avantageusement, le diamètre D du cylindre formé par le module de moto-ventilation 5, et plus précisément par le boîtier 7 de ce dernier, est supérieur à la largeur du manche 2 dans le plan correspondant X-X' / Y-Y'. Par exemple, D=82 mm. En outre, le diamètre D en question est également avantageusement inférieur à la longueur totale L d'extension de la tête de soufflage 3 selon la direction moyenne de soufflage Y-Y' (figure 3). Par exemple, L=116 mm et D=82 mm. Ceci permet, en conjonction notamment avec l'agencement spécifique de la roue de ventilation 6, de favoriser le confort d'utilisation de l'appareil 1 notamment lorsqu'un mouvement de balancier du poignet de l'utilisateur est requis pour effectuer une mise en plis de type « brushing » par exemple.As for the protuberance formed by the motorized ventilation module 5, it advantageously has a substantially cylindrical shape with a circular base along an axis corresponding to the axis of rotation Z-Z '. The protuberance formed by the motorized ventilation module 5 advantageously extends along a height H1 between a first lateral facade clad with the protective grid and at which the air suction port 9 is arranged, and a second opposite lateral facade 19. The second lateral facade 19 is advantageously closed. Behind it is advantageously arranged the drive motor of the ventilation wheel 6, which motor is thus interposed between the second closed side panel 19 (but preferably removable to access the motor) and the ventilation wheel 6. Preferably, the protuberance formed by the blowing head 3 extends, parallel to the direction corresponding to the axis of rotation Z-Z ', along a distance H2 which is advantageously greater than or equal to the extension distance H1 of the protuberance formed by the motorized ventilation module 5 in the same direction Z-Z '. For example, H1 = 70 mm and H2 = 83 mm. This makes it possible to confer a particularly balanced and compact character on the device 1, helping to make it easy and comfortable to use. Advantageously, the diameter D of the cylinder formed by the motorized ventilation module 5, and more precisely by the housing 7 of the latter, is greater than the width of the handle 2 in the corresponding plane XX '/ Y-Y'. For example, D = 82 mm. In addition, the diameter D in question is also advantageously less than the total extension length L of the blowing head 3 along the average blowing direction YY '( figure 3 ). For example, L = 116 mm and D = 82 mm. This makes it possible, in conjunction in particular with the specific arrangement of the ventilation wheel 6, to promote the comfort of use of the device 1, in particular when a rocking movement of the user's wrist is required to carry out a setting. "brushing " type folds for example.

Le fonctionnement et l'utilisation de l'appareil 1 conforme au mode de réalisation illustré aux figures sont par exemple les suivants.The operation and use of the device 1 according to the embodiment illustrated in the figures are for example as follows.

L'utilisateur branche d'abord l'appareil 1 sur le secteur via le cordon 14. L'utilisateur actionne alors la molette formant l'organe de réglage 17 pour mettre en route le module de moto-ventilation 5. La vitesse de rotation de la roue de ventilation 6 peut-être alors réglée au moyen de la molette en question. Sous l'effet de la rotation de la roue de ventilation 6, de l'air ambiant est aspiré par l'ouïe 9 puis refoulé dans le conduit intermédiaire 12 dans lequel il circule selon une trajectoire sensiblement rectiligne parallèlement à la direction moyenne d'extension longitudinale X-X' du manche 2. Le flux d'air atteint ensuite la tête de soufflage au sein de laquelle le flux d'air vient tout d'abord balayer le module électronique 16 pour le refroidir, puis ensuite balayer l'élément chauffant électrique 8 afin d'être réchauffé par ce dernier, pour enfin sortir à l'extérieur par la sortie d'air 4, selon la direction moyenne de soufflage Y-Y'. Afin d'effectuer une mise en plis de type « brushing », l'utilisateur dirige la sortie d'air 4 en direction d'une mèche de cheveux à mettre en forme au moyen d'une brosse, et procède alors à des mouvements de balancier du poignet de la main qui tient le manche 2. Ce mouvement de balancier n'est pas perturbé ou rendu inconfortable par d'éventuels effets gyroscopiques indésirables dus à la rotation de la roue de ventilation 6, grâce à l'orientation spécifique de l'axe de rotation Z-Z' de cette dernière, qui est perpendiculaire au troisième plan P3 dans lequel s'inscrivent à la fois la direction moyenne d'extension longitudinale X-X' du manche 2 et la direction moyenne de soufflage Y-Y'. Dans certains cas, le mouvement de balancier de la main de l'utilisateur peut même être facilité, voire accentué par l'effet gyroscopique dû à la rotation de la roue de ventilation 6.The user first connects the device 1 to the mains via the cord 14. The user then actuates the dial forming the adjustment member 17 to start the motor-ventilation module 5. The speed of rotation of the ventilation wheel 6 can then be adjusted by means of the wheel in question. Under the effect of the rotation of the ventilation wheel 6, ambient air is sucked in by the inlet 9 and then discharged into the intermediate duct 12 in which it circulates in a substantially rectilinear path parallel to the mean direction of extension. longitudinal XX 'of the handle 2. The air flow then reaches the blowing head within which the air flow first sweeps the electronic module 16 to cool it, then sweeps the electric heating element 8 in order to be heated by the latter, to finally exit to the outside through the air outlet 4, according to the average blowing direction Y-Y '. In order to carry out styling of the “ brushing ” type, the user directs the air outlet 4 in the direction of a lock of hair to be shaped by means of a brush, and then proceeds to movements of pendulum of the wrist of the hand which holds the handle 2. This pendulum movement is not disturbed or made uncomfortable by any undesirable gyroscopic effects due to the rotation of the ventilation wheel 6, thanks to the specific orientation of the axis of rotation ZZ 'of the latter, which is perpendicular to the third plane P3 in which both the mean direction of longitudinal extension XX' of the handle 2 and the average blowing direction Y-Y '. In some cases, the swinging movement of the user's hand can even be facilitated, or even accentuated, by the gyroscopic effect due to the rotation of the ventilation wheel 6.
