Description

Brosse soufflante rotative avec ergonomie améliorée Objet de l'invention  Rotating blower with improved ergonomics Object of the invention
[0001] La présente invention se rapporte à un appareil de coiffure de type brosse soufflante rotative comportant une poignée avec deux zones de diamètres différents D1 et D2, le premier diamètre étant sensiblement supérieur au second (D1 >D2), la zone de diamètre supérieur D1 logeant un compresseur permettant l'obtention d'un flux d'air sensiblement constant et une zone de préhension de diamètre D2 permettant une prise en main plus ergonomique par rapport aux appareils de l'état de la technique.  The present invention relates to a rotating fan brush type hairdressing appliance comprising a handle with two zones of different diameters D1 and D2, the first diameter being substantially greater than the second (D1> D2), the zone of greater diameter. D1 housing a compressor for obtaining a substantially constant air flow and a gripping area of diameter D2 allowing a grip more ergonomic compared to the devices of the state of the art.
Etat de la technique State of the art
[0002] Les brosses soufflantes rotatives sont bien connues de l'homme du métier. Elles fonctionnent comme un sèche-cheveux dont la poignée est coaxiale avec l'accessoire de coiffure. Ce type d'appareil comporte généralement un moyen de chauffage et deux moteurs, l'un des deux moteurs permettant d'actionner un ventilateur se trouvant dans la poignée et le deuxième moteur permettant la rotation de l'accessoire de coiffure généralement amovible. Ce deuxième moteur peut se trouver dans la poignée ou en dehors de la poignée.  [0002] Rotating blower brushes are well known to those skilled in the art. They work like a hairdryer whose handle is coaxial with the hair accessory. This type of apparatus generally comprises a heating means and two motors, one of the two motors for actuating a fan located in the handle and the second motor for rotating the generally removable hairdressing accessory. This second motor can be in the handle or outside the handle.

[0004] Le document JP2004-254897 divulgue une brosse soufflante rotative avec un premier moteur agencé dans la poignée qui sert à produire un flux d'air et un deuxième moteur agencé dans la brosse permettant d'entraîner la brosse en rotation.  JP2004-254897 discloses a rotating blower brush with a first motor arranged in the handle which serves to produce an air flow and a second motor arranged in the brush for driving the brush in rotation.
[0005] Le document EP2335515 B1 divulgue une brosse à cheveux électrique comportant une poignée, un élément chauffant, un premier moteur d'entraînement d'un ventilateur et un deuxième moteur d'entraînement en rotation d'un accessoire de coiffure où le ventilateur et le premier moteur sont compris à l'intérieur de la poignée et le second moteur à l'extérieur de la poignée. EP2335515 B1 discloses an electric hairbrush having a handle, a heating element, a first drive motor of a fan and a second drive motor in rotation of a hairdressing accessory where the fan and the first motor is included inside the handle and the second motor outside the handle.
[0006] Les brosses tournantes soufflantes de l'état de la technique ont cependant toutes en commun une poignée très volumineuse et peu ergonomique même lorsque le moteur d'entraînement de l'accessoire se trouve en dehors de celle-ci. Le déplacement du second moteur hors de la poignée a déjà permis de libérer un peu d'espace pour le passage du flux d'air mais même dans cette configuration, la poignée reste encore très volumineuse. Ceci est principalement dû à la difficulté de faire circuler l'air au travers de la poignée avec tous les éléments nécessaires au fonctionnement de l'appareil et en particulier au diamètre souvent important du ventilateur qui doit se trouver dans la poignée et qui aspire l'air à une extrémité de la poignée pour le rejeter de l'autre. The rotating fan brushes of the state of the art, however, all have in common a very bulky and ergonomic handle even when the drive motor of the accessory is outside thereof. The business trip the second motor out of the handle has already freed a little space for the flow of air but even in this configuration, the handle is still very bulky. This is mainly due to the difficulty of circulating the air through the handle with all the elements necessary for the operation of the device and in particular the often large diameter of the fan which must be in the handle and which sucks the air at one end of the handle to reject it from the other.
[0007] La présente invention apporte une amélioration sensible à la circulation du flux d'air et à l'ergonomie d'utilisation de l'appareil. The present invention provides a significant improvement in the flow of air flow and ergonomics of use of the device.
Buts de l'invention Goals of the invention
[0008] La présente invention vise à surmonter les inconvénients de l'état de la technique en proposant une brosse soufflante électrique rotative comportant une poignée avec deux diamètres sensiblement différents permettant d'une part de loger un compresseur performant dans la partie plus large et d'autre part d'affiner au maximum la zone de préhension de l'appareil pour en améliorer l'ergonomie sans sacrifier les fonctions de l'appareil. Résumé de l'invention The present invention aims to overcome the disadvantages of the state of the art by proposing a rotating electric blower having a handle with two substantially different diameters allowing one hand to house a powerful compressor in the wider part and d on the other hand refine the maximum grip area of the device to improve ergonomics without sacrificing the functions of the device.

Brief description of the figures
[0011] La figure 1 représente l'écoulement du flux d'air autour d'une brosse tournante rotative conventionnelle de l'état de la technique. Le flux d'air sortant est mal réparti autour de la brosse et choisit le chemin de sortie de moindre résistance.  Figure 1 shows the flow of air flow around a conventional rotating rotating brush of the state of the art.

Cette représentation permet de montrer la tige-support qui sort de la poignée en supportant le second moteur et qui permet via un élément de couplage polygonal d'entraîner la brosse cylindrique en rotation.  Figure 5 shows the frame of the apparatus according to the invention with the inner elements but without the cylindrical brush.

Description détaillée de l'invention Detailed description of the invention
[0026] La présente invention divulgue une brosse soufflante rotative électrique comportant une poignée de forme allongée particulièrement ergonomique dans laquelle sont agencés un moyen de chauffage et un compresseur entraîné par un premier moteur permettant d'aspirer l'air à une extrémité de l'appareil et de le souffler à travers des éléments chauffants, vers un accessoire rotatif. L'accessoire rotatif est de préférence une brosse cylindrique amovible avec des touffes de poils, agencé sur une tige-support à l'extrémité opposée de la poignée et entraîné par un second moteur agencé en dehors de la poignée sur une tige-support situé dans l'axe longitudinal de la poignée. Cette configuration permet une mise en forme des cheveux plus rapide et plus homogène que les appareils de l'état de la technique (Fig.3). The present invention discloses an electric rotary blower having a particularly ergonomic elongated handle in which are arranged a heating means and a compressor driven by a first motor for sucking air at one end of the apparatus and blow it through heating elements to a rotating accessory. The rotating accessory is preferably a removable cylindrical brush with tufts of bristles, arranged on a support rod at the opposite end of the handle and driven by a second motor arranged outside the handle on a support rod located in the longitudinal axis of the handle. This configuration makes hair shaping faster and more homogeneous than the apparatus of the state of the art (FIG. 3).
[0027] L'emplacement de passage de l'air entre la poignée et la tige-support du second moteur a fait l'objet d'une étude aérodynamique approfondie. Par rapport aux configurations de l'état de la technique, la forme aérodynamique en forme de pointe associée à des ailettes de type empennage de fusée permet un écoulement d'air optimisé à travers l'appareil. Il simplifie également la construction de l'appareil au niveau des pièces moulées en matière plastique et permet une fixation solide et simplifiée de ladite tige-support à la poignée. La poignée est formée de deux demi-coques qui sont assemblées et resserrées autour des ailerons de fixation de la tige support du second moteur par un anneau d'assemblage. Cette construction permet de simplifier la construction de l'appareil tout en assurant la rigidité de la fixation de la tige-support du second moteur (Fig.12). The air passage location between the handle and the support rod of the second engine has been the subject of a thorough aerodynamic study. Compared to the prior art configurations, the aerodynamic tip-shaped shape associated with rocket-like fin fins allows optimized airflow through the apparatus. It also simplifies the construction of the apparatus at the molded plastic parts and allows a solid and simplified attachment of said support rod to the handle. The handle is formed of two half-shells which are assembled and tightened around the fixing fins of the support rod of the second motor by an assembly ring. This construction makes it possible to simplify the construction of the apparatus while ensuring the rigidity of the fixation of the support rod of the second motor (FIG. 12).
[0028] Pour améliorer l'ergonomie de la brosse soufflante rotative selon la présente invention, celle-ci comporte une poignée avec deux diamètres D1 et D2 sensiblement différents. Une telle brosse soufflante, muni d'une brosse cylindrique avec des touffes de poils, et des sorties d'air, non pas disposées de manière uniforme sur la brosse cylindrique, mais judicieusement agencées permet une mise en forme des cheveux par enroulement d'une mèche entière ou partielle autour de la brosse. La brosse cylindrique amovible comporte des touffes de poils et des ouvertures de sortie d'air réparties par section ou par nombre décroissant vers l'extrémité de l'appareil sur sa surface cylindrique (voir figures 8,10 et 1 1 ). Cet agencement en section et/ou en nombre d'ouvertures d'air décroissantes vers l'extrémité de l'accessoire associé à une poignée ergonomique comportant un compresseur capable de maintenir un flux d'air sensiblement constant, même lorsque les ouvertures de sortie d'air sur la brosse sont partiellement obstruées, permet une répartition homogène du flux d'air autour de la brosse (voir figures 1 et 2). To improve the ergonomics of the rotary blower brush according to the present invention, it comprises a handle with two diameters D1 and D2 substantially different. Such blower brush, provided with a cylindrical brush with tufts of bristles, and air outlets, not uniformly arranged on the cylindrical brush, but judiciously arranged allows shaping of hair by winding a entire or partial wick around the brush. The removable cylindrical brush has tufts of bristles and air outlet openings distributed by section or by decreasing number towards the end of the apparatus on its cylindrical surface (see FIGS. 8, 10 and 11). This arrangement section and / or number of openings decreasing air towards the end of the accessory associated with an ergonomic handle having a compressor capable of maintaining a flow of air substantially constant, even when the air outlet openings on the brush are partially obstructed, allows a homogeneous distribution of the air flow around the brush (see Figures 1 and 2).
[0029] Afin d'optimiser le flux d'air, l'aspiration d'air, à travers la grille de protection extérieure, doit être centrée sur l'axe longitudinal de l'appareil, ce qui a pour conséquence un positionnement décentré de l'alimentation électrique. Le positionnement décentré de l'alimentation électrique entraîne la nécessité d'un contact électrique rotatif au niveau du point de connexion avec le câble pour améliorer l'ergonomie de l'appareil lors de différentes prises en main par l'utilisateur (voir figures 9 et 13).  To optimize the flow of air, the air intake, through the outer protection grid, must be centered on the longitudinal axis of the device, which results in an off-center positioning of the power supply. The off-center positioning of the power supply causes the need for a rotating electrical contact at the point of connection with the cable to improve the ergonomics of the device during different grips by the user (see FIGS. 13).
[0030] Par le choix d'un compresseur performant qui permet de maintenir un flux d'air sensiblement constant et son positionnement dans une partie de la poignée de diamètre agrandi D1 et en guidant ce flux d'air redressé par des ailettes, pour éviter les turbulences, à travers une poignée amincie de diamètre D1 et une configuration étudiée des résistances chauffantes (voir figures 15 et 16) on parvient à améliorer l'ergonomie de la zone de préhension tout en générant un flux d'air tout à fait uniforme au travers d'ouvertures sur la brosse cylindrique via la diminution du nombre et/ou de la section des ouvertures en s'éloignant de la poignée. Ceci peut être réalisé de différentes manières en réalisant soit des ouvertures de plus en plus petites le long de l'axe longitudinal de la brosse cylindrique soit en en diminuant le nombre.  By the choice of a high performance compressor that maintains a substantially constant air flow and its positioning in a portion of the enlarged diameter handle D1 and guiding the air flow straightened by fins, to avoid turbulence, through a thinned handle of diameter D1 and a studied configuration of the heating resistances (see FIGS. 15 and 16), it is possible to improve the ergonomics of the gripping zone while generating a completely uniform flow of air at the same time. through openings on the cylindrical brush via the decrease in the number and / or the section of the openings away from the handle. This can be achieved in different ways by making either smaller and smaller apertures along the longitudinal axis of the cylindrical brush or by decreasing the number.
[0031] L'appareil selon la présente invention comporte également un mécanisme de reconnaissance de l'accessoire utilisé, pax exemple des brosses cylindriques de diamètre différent. Ce mécanisme de reconnaissance permet un asservissement du flux d'air, de la puissance du chauffage et de la vitesse de rotation de la brosse rotative.  The apparatus according to the present invention also comprises a mechanism for recognizing the accessory used, for example cylindrical brushes of different diameter. This recognition mechanism allows control of the air flow, the heating power and the speed of rotation of the rotary brush.
[0032] Selon un mode d'exécution préféré de l'invention, les ouvertures de sortie d'air sur la brosse cylindrique sont disposées au moins en partie en cercles concentriques dont le diamètre devient de plus en plus petit en s'éloignant de la poignée (voir figures 10 et 1 1 ). According to a preferred embodiment of the invention, the air outlet openings on the cylindrical brush are arranged at least partly in concentric circles whose diameter becomes smaller and smaller away from the handle (see Figures 10 and 1 1).
[0033] La tige-support moteur sortant de la poignée, comportant dans sa partie creuse le moteur d'entraînement de la brosse et une boite de vitesse comporte un élément de couplage polygonal mâle à l'extrémité qui coopère avec un évidement femelle correspondant sur la brosse permettant un montage et démontage rapide de l'accessoire. La tige-support, une fois assemblée, est refermée par un capuchon qui referme l'ensemble (voir figure 18).  The motor support rod leaving the handle, having in its hollow portion the drive motor of the brush and a gearbox comprises a male polygonal coupling element at the end which cooperates with a corresponding female recess on the brush allows a quick assembly and disassembly of the accessory. The support rod, once assembled, is closed by a cap that closes the assembly (see Figure 18).
[0034] Dans un mode d'exécution préféré de l'invention l'élément de couplage est carré et est directement fixé sur l'axe de la boite de vitesse du second moteur sans aucune pièce intermédiaire. Les moteurs utilisés sont de préférence des moteurs sans balais, mais on peut également envisager un moteur ordinaire. Dans les deux cas une limitation de couple de force ou un débrayage mécanique peuvent être envisagés en cas de dépassement d'un couple de force donné pour ne pas forcer le moteur lors d'une utilisation inadéquate. In a preferred embodiment of the invention the coupling element is square and is directly fixed on the axis of the gearbox of the second motor without no intermediate part. The motors used are preferably brushless motors, but one can also consider an ordinary engine. In both cases a force torque limitation or mechanical disengagement can be envisaged if a given torque is exceeded in order not to force the motor during improper use.
[0035] A l'une des extrémités de la poignée, côté compresseur, se situe l'aspiration d'air qui passe à travers une grille extérieure, un filtre et une grille interne. Le filtre, généralement en mousse plastique, est maintenu par un support, ici en forme de croisillon (voir figure 13). Pour permettre le nettoyage de ces éléments, la grille d'aspiration extérieure est montée sur charnière.  At one end of the handle, compressor side, is the air intake which passes through an outer gate, a filter and an internal grid. The filter, generally made of plastic foam, is held by a support, here in the form of a spider (see FIG. 13). To allow cleaning of these elements, the external suction grille is hinged.
[0036] La brosse cylindrique avec ses ouvertures d'évacuation d'air est généralement réalisée en métal, de préférence en aluminium et comporte de préférence une couche céramique pour une répartition plus uniforme de la chaleur. La brosse cylindrique comporte également un mécanisme de verrouillage légèrement protubérant par rapport à la surface refermant le cylindre (voir figures 10 et 1 1 )  The cylindrical brush with its air evacuation openings is generally made of metal, preferably aluminum and preferably comprises a ceramic layer for a more uniform distribution of heat. The cylindrical brush also has a locking mechanism slightly protruding relative to the surface closing the cylinder (see FIGS. 10 and 11)
[0037] L'appareil comporte également un ioniseur situé dans la poignée dans le prolongement du premier moteur pour ne pas perturber le flux d'air. Il est aussi muni d'une double grille de protection au niveau de l'aspiration d'air.  The apparatus also comprises an ionizer located in the handle in the extension of the first motor so as not to disturb the air flow. It is also equipped with a double protection grille at the level of the air intake.
[0038] Comme toutes les brosses soufflantes rotatives, il comporte aussi un interrupteur principal réglant le flux et la température de l'air sortant de la poignée et un interrupteur secondaire permettant de choisir le sens horaire ou antihoraire de rotation de la brosse cylindrique. Cet interrupteur est monté sur un système de bascule à ressort lui permettant de retrouver automatiquement sa position d'équilibre après avoir été actionné (voir figure 14).  Like all rotating fan brushes, it also includes a main switch regulating the flow and temperature of the air exiting the handle and a secondary switch for choosing the clockwise or counterclockwise rotation of the cylindrical brush. This switch is mounted on a spring latch system allowing it to automatically regain its equilibrium position after being actuated (see Figure 14).
[0039] L'enroulement des fils de la résistance chauffante peut avoir une configuration de bobinage en étoile (voir figures 15 et 16). The winding of the son of the heating resistor may have a star winding configuration (see Figures 15 and 16).
[0040] Il a été constaté que la régulation de la température était facilitée en positionnant une sonde de température au bout de la tige-support plutôt que dans la poignée à cause de la proximité des éléments chauffants irradiant la chaleur.  It has been found that the regulation of the temperature was facilitated by positioning a temperature probe at the end of the rod-holder rather than in the handle because of the proximity of the heating elements radiating heat.
Pour respecter la réglementation en matière de sécurité électrique, la brosse cylindrique pourra être montée fixe (non amovible) ou son enlèvement lié à un mécanisme coupant le contact électrique lors de l'enlèvement de la brosse cylindrique. To comply with the regulations on electrical safety, the cylindrical brush may be fixed mounted (non-removable) or its removal linked to a mechanism cutting the electrical contact during the removal of the cylindrical brush.
