Description

SECHE-CHEVEUX HAIR DRYER
La présente invention concerne un appareil de coiffure du type comportant, à l'intérieur d'un boîtier, des moyens de mise en circulation d'un flux d'air chaud appliqué à une ouverture de sortie du boîtier pour réaliser un séchage et/ou une mise en forme des cheveux.The present invention relates to a hairstyling device of the type comprising, inside a housing, means for circulating a flow of hot air applied to an outlet opening of the housing for drying and / or hair shaping.
Ces appareils sont souvent équipés de moyens de commande et réglage des paramètres de sortie du flux d'air, notamment de la vitesse et/ou de la température du flux d'air soufflé par l'appareil. La présente invention concerne plus particulièrement un sèche-cheveux muni de moyens de commande et de réglage permettant de sélectionner les vitesses et les températures du flux d'air utilisé pour le séchage ou la mise en forme de la chevelure.These devices are often equipped with means for controlling and adjusting the parameters of the air flow output, in particular the speed and / or the temperature of the air flow blown by the device. The present invention relates more particularly to a hair dryer provided with control and adjustment means making it possible to select the speeds and temperatures of the air flow used for drying or shaping the hair.
Des sèche-cheveux connus de l'état de la technique comportent généralement un commutateur à trois positions, une position d'arrêt et deux autres permettant de passer d'une valeur de faible puissance de l'élément chauffant et de la vitesse du flux d'air, à une valeur plus élevée de ces paramètres. Dans le document DE 39 03 442, un tel commutateur présente, de plus, une fenêtre d'affichage de la position choisie, permettant d'informer rapidement sur cette position. Toutefois, un tel appareil ne permet pas de régler indépendamment la valeur de la température et celle de la vitesse du flux d'air.Hair dryers known in the state of the art generally comprise a switch with three positions, a stop position and two others allowing to pass from a value of low power of the heating element and of the speed of the flow d 'air, to a higher value of these parameters. In document DE 39 03 442, such a switch also presents a window for displaying the selected position, making it possible to quickly inform about this position. However, such an apparatus does not make it possible to independently regulate the value of the temperature and that of the speed of the air flow.
Un appareil similaire est décrit dans le document DE 91 14 242 U où la poignée du sèche-cheveux comporte également un bouton d'actionnement permettant à l'utilisateur de régler la valeur du couple vitesse et température de l'air et de l'afficher dans une fenêtre de la poignée. Cet appareil comporte en outre une touche de pression agencée au centre dudit bouton d'actionnement pour couper l'alimentation de l'élément chauffant et envoyer de l'air froid à travers la sortie lorsque la touche de pression est actionnée. Comme dans le document précédent, cet appareil ne permet pas un réglage individuel de la température et de la vitesse de l'air et, de surcroît, il n'informe pas l'utilisateur par un affichage spécifique lorsque l'appareil fonctionne selon un autre mode que celui de réglage, notamment celui correspondant à l'envoi d'air froid à travers l'orifice de sortie d'air de l'appareil.A similar device is described in document DE 91 14 242 U where the handle of the hair dryer also includes an actuation button allowing the user to adjust the value of the couple speed and temperature of the air and to display it. in a handle window. This apparatus further comprises a pressure button arranged in the center of said actuation button to cut the supply to the heating element and send cold air through the outlet when the pressure button is actuated. As in the previous document, this device does not allow individual adjustment of the temperature and air speed and, moreover, it does not inform the user by a display specific when the appliance operates in a mode other than that of adjustment, in particular that corresponding to the sending of cold air through the air outlet orifice of the appliance.
On connaît par ailleurs d'autres appareils ayant des commutateurs indépendants pour commander l'un la puissance de l'élément chauffant et l'autre la vitesse du flux d'air. De tels appareils comportent deux touches ayant chacune plusieurs positions possibles. Ainsi, de nombreuses combinaisons sont possibles, la multiplicité de toutes ces combinaisons pouvant avoir comme conséquence une perte de temps pour l'utilisateur dans le choix du mode de séchage. De plus, un utilisateur non averti pourrait même choisir un mauvais couple température et vitesse du flux d'air pouvant allonger le temps de séchage, voire à la limite, abîmer les cheveux.Other devices are also known having independent switches for controlling one the power of the heating element and the other the speed of the air flow. Such devices have two keys, each having several possible positions. Thus, many combinations are possible, the multiplicity of all these combinations can result in a loss of time for the user in the choice of drying mode. In addition, an uninformed user could even choose the wrong couple of temperature and speed of the air flow that can lengthen the drying time, or even limit the damage to the hair.
Le document JP 4-246303 décrit un sèche-cheveux comportant des moyens de commande des paramètres de fonctionnement de l'appareil, notamment température et vitesse de l'air, ainsi que des moyens de mise en mémoire des valeurs présélectionnées, valeurs qui peuvent être retrouvées lors d'une utilisation ultérieure. De construction complexe, cet appareil s'est avéré également d'une utilisation difficile à cause de la multiplicité de touches de commande et du fait que l'utilisateur doit trouver lui même les bonnes touches afin de mettre en mémoire les valeurs des paramètres de fonctionnement. De surcroît, l'utilisateur étant à même de sélectionner et mettre en mémoire un couple température et vitesse d'air, il peut y avoir le danger qu'il sélectionne des valeurs inadéquates, éloignées de celles optimales adaptées à une utilisation spécifique.Document JP 4-246303 describes a hair dryer comprising means for controlling the operating parameters of the appliance, in particular air temperature and speed, as well as means for storing the preset values, values which can be found during later use. Complex in construction, this device has also proved to be difficult to use because of the multiplicity of control keys and the fact that the user must find the correct keys himself in order to store the values of the operating parameters. . In addition, the user being able to select and store a couple of temperature and air speed, there may be the danger that he selects inadequate values, far from the optimal ones adapted to a specific use.
Par ailleurs, le document US 6 393 718 décrit un sèche-cheveux comportant, à l'intérieur de son boîtier, un ventilateur actionné par un moteur électrique pour envoyer l'air aspiré à travers un élément chauffant vers l'orifice de sortie d'air, ainsi qu'un générateur d'ions prévu pour envoyer un flux d'ions à la sortie d'air du sèche-cheveux. La poignée de ce boîtier comporte un panneau de commande à plusieurs touches sensitives dont l'une commande le fonctionnement du générateur d'ions et une autre le réglage de la vitesse de l'air. Des indicateurs lumineux sont prévus sur la même poignée, l'un pour témoigner de l'état de mise en marche du générateur d'ions et trois autres pour indiquer la valeur de la vitesse de l'air soufflé par l'appareil. Ce document ne décrit qu'un appareil muni de plusieurs touches de commande aptes à régler un paramètre de fonctionnement indépendant. Il ne décrit pas de bouton de commande d'un mode de fonctionnement correspondant à un réglage combiné d'au moins deux paramètres en même temps.Furthermore, document US Pat. No. 6,393,718 describes a hair dryer comprising, inside its housing, a fan actuated by an electric motor to send the air sucked through a heating element towards the outlet of the air, as well as an ion generator intended to send an ion flow to the air outlet of the hair dryer. The handle of this box has a control panel with several sensitive buttons, one of which controls the operation of the another ion generator and another one to adjust the air speed. Indicators are provided on the same handle, one to indicate the start-up state of the ion generator and three others to indicate the value of the speed of the air blown by the device. This document describes only one device provided with several control keys capable of adjusting an independent operating parameter. It does not describe an operating mode control button corresponding to a combined setting of at least two parameters at the same time.
Le but de l'invention est de remédier au moins en partie à ces inconvénients et de proposer un sèche-cheveux comportant un dispositif amélioré de contrôle de la puissance de chauffe et de la vitesse de l'air permettant un traitement rapide, tout en offrant une bonne protection de la chevelure lors du traitement.The object of the invention is to remedy these drawbacks at least in part and to propose a hair dryer comprising an improved device for controlling the heating power and the air speed allowing rapid treatment, while offering good protection of the hair during treatment.
Un but supplémentaire de l'invention est un sèche-cheveux comportant des moyens de commande du mode de fonctionnement, choisi parmi plusieurs modes possibles, qui soient aptes à indiquer clairement le mode choisi permettant une utilisation facilitée de l'appareil, tout en laissant la possibilité à l'utilisateur de régler les paramètres de fonctionnement.A further object of the invention is a hair dryer comprising means for controlling the operating mode, chosen from several possible modes, which are capable of clearly indicating the chosen mode allowing easier use of the appliance, while leaving the possibility for the user to adjust the operating parameters.
Un autre but de l'invention est un sèche-cheveux muni de moyens d'indication permettant une bonne visualisation sous tous les angles.Another object of the invention is a hair dryer provided with indication means allowing good viewing from all angles.
Un autre but de l'invention est de proposer un sèche-cheveux comportant des moyens de commande et d'indication des valeurs sélectionnées de température et de vitesse d'air qui soient de construction simplifiée, tout en étant fiables en fonctionnement et faciles à industrialiser pour un coût moindre.Another object of the invention is to propose a hair dryer comprising means for controlling and indicating the selected values of temperature and air speed which are of simplified construction, while being reliable in operation and easy to industrialize. for a lower cost.
Ces buts sont atteints avec un sèche-cheveux comportant un boîtier muni d'une ouverture d'entrée d'air aspiré par un moto-ventilateur et envoyé vers une ouverture de sortie d'air à travers un élément chauffant électrique, des moyens de commande du mode de fonctionnement du sèche-cheveux selon différents niveaux de puissance de l'élément chauffant et/ou du ventilateur, ainsi qu'un afficheur de la sélection, du fait qu'il comprend un bouton de commande permettant de basculer entre un mode de fonctionnement dit de réglage manuel et un mode de fonctionnement dit de réglage automatique prédéterminé, ledit bouton de commande étant relié à l'afficheur pour informer du mode de fonctionnement choisi.These aims are achieved with a hair dryer comprising a housing provided with an air inlet opening drawn in by a motor-fan and sent to an air outlet opening through an electric heating element, control means. the operation mode of the hair dryer according to different power levels of the heating element and / or the fan, as well as a selection display, because it comprises a control button making it possible to switch between a so-called manual adjustment operating mode and a so-called predetermined automatic adjustment operating mode, said control button being connected to the display to inform of the operating mode chosen.
Par mode de fonctionnement dit de réglage manuel on comprend un mode de fonctionnement qui permet à l'utilisateur d'ajuster indépendamment la température ou la vitesse de l'air selon ses propres critères de choix. L'appareil comporte en ce sens plusieurs commutateurs qui sont activés un par un dans ce mode de réglage manuel pour réaliser chacun un réglage séparé d'un paramètre indépendant, par exemple : le réglage de la température de l'air, le réglage de la vitesse de l'air, voire la commande de l'émission d'un flux d'ions, etc.By so-called manual adjustment operating mode is understood an operating mode which allows the user to independently adjust the temperature or the air speed according to his own selection criteria. In this sense, the apparatus comprises several switches which are activated one by one in this manual adjustment mode, each of which carries out a separate adjustment of an independent parameter, for example: adjusting the air temperature, adjusting the air speed, or even the control of the emission of an ion flow, etc.
Par mode de fonctionnement dit de réglage automatique prédéterminé on comprend un mode de fonctionnement préétabli permettant un réglage combiné d'au moins deux paramètres simultanément. Dans un tel mode de réglage automatique prédéterminé, le niveau de puissance de l'élément chauffant et la vitesse du moto-ventilateur sont imposés par le constructeur de manière à assurer, lors du fonctionnement et sans aucun autre réglage préalable, un séchage rapide, une bonne mise en forme et une protection des cheveux. Ces paramètres, établis lors des tests effectués en laboratoire, ont comme plage de valeurs pour la température : de 30° à 80°C et pour la vitesse d'air de 15 m3/h àBy so-called predetermined automatic adjustment operating mode is understood a predetermined operating mode allowing a combined adjustment of at least two parameters simultaneously. In such a predetermined automatic adjustment mode, the power level of the heating element and the speed of the fan motor are imposed by the manufacturer so as to ensure, during operation and without any other prior adjustment, rapid drying, good shaping and protection of the hair. These parameters, established during laboratory tests, have the following values for the temperature: from 30 ° to 80 ° C and for the air speed from 15 m 3 / h to
90 mTh.90 mTh.
Un tel mode de réglage automatique prédéterminé ou préétabli peut, par exemple, être un mode de séchage optimum qui assure un séchage rapide sans abîmer les cheveux. Dans une autre variante, le mode de fonctionnement prédéterminé peut être un mode appelé air froid lors duquel la température de traitement choisie est très basse, l'élément chauffant pouvant être coupé, voire alimenté à très faible puissance, la vitesse ayant une valeur choisie dans la plage susmentionnée. Dans encore une autre variante de réalisation, le mode préétabli peut avoir une température choisie dans la plage susmentionnée, alors que la vitesse peut avoir une valeur maximale, assurant un séchage ultrarapide. Dans une variante supplémentaire, le mode préétabli peut être un mode confort, les valeurs de vitesse et de température étant choisies pour traiter les cheveux sensibles. On peut également envisager un mode brushing où la mise en plis de la coiffure est facilitée, etc.Such a predetermined or preset automatic adjustment mode can, for example, be an optimum drying mode which ensures rapid drying without damaging the hair. In another variant, the predetermined operating mode can be a mode called cold air during which the chosen treatment temperature is very low, the heating element being able to be cut or even supplied at very low power, the speed having a value chosen in the above range. In yet another alternative embodiment, the preset mode may have a temperature chosen from the above-mentioned range, while the speed can have a maximum value, ensuring ultra-fast drying. In an additional variant, the preset mode can be a comfort mode, the speed and temperature values being chosen to treat sensitive hair. We can also consider a brushing mode where styling of the hairstyle is facilitated, etc.
Plus particulièrement selon l'invention, le mode de fonctionnement choisi, de réglage manuel ou automatique prédéterminé, est obtenu en actionnant un bouton de commande qui agit sur un interrupteur électrique pour changer les paramètres de fonctionnement de l'élément chauffant et du moto-ventilateur. Ce bouton de commande actionne en même temps un afficheur qui indique le mode courant de fonctionnement de l'appareil. Ainsi, avec un sèche-cheveux de l'invention, l'utilisateur peut choisir soit un séchage rapide, sans réglage, mais qui est, par exemple, optimum, soit un autre mode où il peut régler les paramètres de fonctionnement du sèche-cheveux, le mode de fonctionnement rendu actif étant indiqué de manière claire par l'afficheur de l'invention. De plus, un tel appareil permet à l'utilisateur d'être guidé dans son choix, en lui proposant un couple adéquat de vitesse d'air et de température, ce qui assure un bon traitement des cheveux et un gain de temps important.More particularly according to the invention, the chosen operating mode, of predetermined manual or automatic adjustment, is obtained by actuating a control button which acts on an electric switch to change the operating parameters of the heating element and of the motorized fan. . This control button simultaneously activates a display which indicates the current operating mode of the device. Thus, with a hair dryer of the invention, the user can choose either quick drying, without adjustment, but which is, for example, optimum, or another mode where he can adjust the operating parameters of the hair dryer. , the operating mode made active being clearly indicated by the display of the invention. In addition, such a device allows the user to be guided in his choice, by offering him an adequate couple of air speed and temperature, which ensures good treatment of the hair and a significant saving of time.
Ainsi, le bouton de commande de l'appareil de l'invention permet de basculer entre un mode de fonctionnement où l'utilisateur peut régler manuellement les différents paramètres de l'appareil et un mode où ce réglage est fait automatiquement par l'appareil, chaque mode de fonctionnement étant indiqué par un afficheur prévu à cet effet. Un tel appareil présente une flexibilité considérable de ses moyens de commande, tout en permettant un fonctionnement optimum préétabli.Thus, the control button of the device of the invention makes it possible to switch between an operating mode where the user can manually adjust the various parameters of the device and a mode where this adjustment is made automatically by the device, each operating mode being indicated by a display provided for this purpose. Such an apparatus has considerable flexibility in its control means, while allowing pre-established optimum operation.
De préférence, ledit bouton de commande est relié à l'afficheur par un mécanisme de commande.Preferably, said control button is connected to the display by a control mechanism.
Un affichage électronique du type écran à cristaux liquides aurait pu également être envisagé. On préfère cependant un mécanisme de commande permettant d'actionner mécaniquement ledit afficheur, car un tel mécanisme ne nécessite pas une alimentation électrique pour fonctionner. Ceci rend l'afficheur fonctionnel à tout moment, même quand le sèche-cheveux n'est pas alimenté en électricité, par exemple lorsqu'il est exposé sur un lieu d'achat. De surcroît, une telle solution s'avère plus simple et fiable en fonctionnement.An electronic display of the liquid crystal screen type could also have been envisaged. However, we prefer a control mechanism allowing to actuate said display mechanically, since such a mechanism does not require an electrical supply to operate. This makes the display functional at all times, even when the hairdryer is not supplied with electricity, for example when it is displayed at a place of purchase. In addition, such a solution is simpler and more reliable in operation.
Avantageusement, ledit afficheur est disposé dans la poignée du sèche-cheveux et il comporte une fenêtre transparente derrière laquelle défilent deux surfaces indicatrices mises en mouvement par ledit mécanisme de commande.Advantageously, said display is placed in the handle of the hair dryer and it includes a transparent window behind which scroll two indicator surfaces set in motion by said control mechanism.
Ainsi, une fenêtre transparente peut être disposée à l'extérieur de la poignée, alors que le mécanisme de commande et les surfaces indicatrices peuvent. être agencées à l'intérieur de la poignée, derrière ladite fenêtre, ce qui permet d'avoir une construction compacte de l'appareil, tout en ayant une bonne visibilité du message véhiculé par les surfaces indicatrices. Ceci permet l'affichage de messages différents dans une même fenêtre de la poignée. Dans une variante, on pourrait remplacer la fenêtre transparente par une simple ouverture pratiquée dans la poignée du sèche-cheveux.Thus, a transparent window can be arranged outside the handle, while the control mechanism and the indicator surfaces can. be arranged inside the handle, behind said window, which makes it possible to have a compact construction of the device, while having good visibility of the message conveyed by the indicating surfaces. This allows the display of different messages in the same window of the handle. Alternatively, the transparent window could be replaced by a simple opening in the handle of the hair dryer.
De préférence, ledit mécanisme de commande transforme le mouvement de coulissement longitudinal du bouton de commande en un mouvement de pivotement des surfaces indicatrices autour d'un axe parallèle à la direction de coulissement du bouton de commande.Preferably, said control mechanism transforms the longitudinal sliding movement of the control button into a pivoting movement of the indicator surfaces about an axis parallel to the sliding direction of the control button.
Le bouton de commande est de préférence localisé dans la poignée du sèche- cheveux, pour une meilleure maniabilité de l'appareil, le mouvement de coulissement longitudinal dans la direction de la poignée étant utilisé d'abord pour actionner les contacts de l'interrupteur qui commute entre les deux modes de fonctionnement possibles. Ce mouvement de coulissement du bouton de commande est également utilisé pour actionner un afficheur qui change d'image derrière une fenêtre du boîtier, notamment par un mouvement de pivotement des surfaces indicatrices. Un pivotement de ces surfaces indicatrices autour d'un axe parallèle à la direction de coulissement du bouton de commande permet d'amener ces surfaces dans un plan parallèle à cette direction, pour une meilleure visibilité.The control button is preferably located in the handle of the hairdryer, for better maneuverability of the appliance, the longitudinal sliding movement in the direction of the handle being used first to actuate the contacts of the switch which switches between the two possible operating modes. This sliding movement of the control button is also used to actuate a display which changes image behind a window of the housing, in particular by a pivoting movement of the indicator surfaces. A pivoting of these indicator surfaces around an axis parallel to the sliding direction of the control button allows to bring these surfaces in a plane parallel to this direction, for better visibility.
Utilement, lesdites surfaces indicatrices forment un angle supérieur à 30° entre elles et sont amenées à pivoter autour de tourillons situés en extrémité de chaque surface.Usefully, said indicator surfaces form an angle greater than 30 ° therebetween and are caused to pivot around pins located at the end of each surface.
L'angle compris entre les deux surfaces est supérieur à 30°, de préférence égal à 90°. Ainsi, chaque surface indicatrice, initialement agencée en parallèle et à faible distance de la fenêtre d'affichage, reste parallèle et proche de la fenêtre d'affichage après pivotement ce qui permet une bonne visibilité, à travers la fenêtre transparente, des indications inscrites sur chaque surface indicatrice.The angle between the two surfaces is greater than 30 °, preferably equal to 90 °. Thus, each indicator surface, initially arranged in parallel and at a short distance from the display window, remains parallel and close to the display window after pivoting, which allows good visibility, through the transparent window, of the indications inscribed on each indicator surface.
De préférence, lesdites surfaces indicatrices sont entraînées en pivotement en étant actionnées par un levier mis en mouvement par une came reliée au bouton de commande.Preferably, said indicator surfaces are pivoted by being actuated by a lever set in motion by a cam connected to the control button.
Ceci permet d'amplifier le mouvement reçu par la came du bouton de commande et d'obtenir une bonne amplitude du mouvement de pivotement pour les surfaces indicatrices, tout en ayant une faible course du bouton de commande.This makes it possible to amplify the movement received by the cam of the control button and to obtain a good amplitude of the pivoting movement for the indicator surfaces, while having a short stroke of the control button.
Avantageusement, lesdites surfaces indicatrices sont reliées ensemble par deux secteurs dentés qui s'engrènent avec des sections de crémaillère montées fixes par rapport au boîtier.Advantageously, said indicator surfaces are connected together by two toothed sectors which mesh with sections of rack mounted fixed relative to the housing.
Une telle solution s'avère simple et facile à industrialiser et elle assure un mouvement continu, sans à coups, des surfaces indicatrices lors de leur pivotement.Such a solution turns out to be simple and easy to industrialize and it ensures a continuous movement, without jerks, of the indicating surfaces during their pivoting.
Utilement, la première surface indicatrice porte des indications différentes de celles inscrites sur la deuxième surface indicatrice, ces indications étant sous forme de texte. Ceci permet d'indiquer, en faisant défiler chaque surface derrière la fenêtre transparente de l'afficheur, un message sous forme de texte indiquant de manière claire, sans équivoque, le mode de fonctionnement de l'appareil.Usefully, the first indicator surface bears indications different from those written on the second indicator surface, these indications being in the form of text. This makes it possible to indicate, by scrolling each surface behind the transparent window of the display, a message in the form of text clearly, unequivocally indicating the operating mode of the device.
Avantageusement, ledit afficheur comporte une fenêtre transparente rectangulaire, disposée avec sa plus grande dimension dans le sens longitudinal de la poignée.Advantageously, said display comprises a transparent rectangular window, arranged with its largest dimension in the longitudinal direction of the handle.
Ceci permet d'inscrire un texte vertical sur la surface indicatrice visible à travers la fenêtre transparente de l'afficheur, ce texte vertical étant de surcroît, une rangée verticale de repères par rapport auxquels est amené à coulisser verticalement un curseur de réglage des paramètres de fonctionnement.This makes it possible to write a vertical text on the indicator surface visible through the transparent window of the display, this vertical text being moreover, a vertical row of marks relative to which is brought to slide vertically a slider for adjusting the parameters of operation.
Les caractéristiques de l'invention peuvent se retrouver de manière avantageuse dans un appareil de coiffure ou de traitement des cheveux comportant un boîtier renfermant un moto-ventilateur et/ou un élément chauffant électrique, des moyens de commande du mode de fonctionnement de l'appareil selon différents niveaux de puissance de l'élément chauffant et/ou du ventilateur, ainsi qu'un afficheur de la sélection, du fait qu'il comprend un bouton de commande permettant de basculer entre un mode de fonctionnement dit de réglage manuel et un mode de fonctionnement dit de réglage automatique prédéterminé, ledit bouton de commande étant relié à l'afficheur pour informer du mode de fonctionnement choisi.The characteristics of the invention can be found advantageously in a hairdressing or hair treatment appliance comprising a housing containing a motor-fan and / or an electric heating element, means for controlling the operating mode of the appliance. according to different power levels of the heating element and / or the fan, as well as a selection display, due to the fact that it includes a control button making it possible to switch between an operating mode known as manual adjustment and a mode said predetermined automatic adjustment operating mode, said control button being connected to the display to inform of the operating mode chosen.
Un tel appareil de coiffure peut être une brosse chauffante et/ ou soufflante, un peigne chauffant et/ou soufflant ou tout autre appareil prévu pour réaliser une mise en forme et/ou un séchage des cheveux.Such a hairstyling device can be a heating and / or blowing brush, a heating and / or blowing comb or any other device intended for shaping and / or drying the hair.
L'invention sera mieux comprise à l'étude d'un mode de réalisation pris à titre nullement limitatif et illustré aux figures annexées dans lesquelles :The invention will be better understood from the study of an embodiment taken without any limitation being implied and illustrated in the appended figures in which:

L'appareil illustré en figure 1 est un sèche-cheveux comportant un boîtier 1 tubulaire muni d'une poignée 7 disposée transversalement au boîtier 1. Le boîtier 1 renferme des moyens de ventilation représentés par un groupe moto- ventilateur 4 (fig.3), prévus pour aspirer l'air à l'intérieur du boîtier à partir d'une entrée d'air 2. L'air aspiré est ensuite dirigé vers une sortie d'air 3 en étant éventuellement chauffé au préalable par un élément chauffant électrique placé à l'intérieur du boîtier, entre l'ensemble moteur électrique et ventilateur 4 et la sortie d'air 3. L'extrémité de sortie d'air de l'appareil peut être munie de divers accessoires tels que des buses, des diffuseurs, des brosses ou des peignes permettant de réaliser le séchage et/ou la mise en forme de la coiffure.The apparatus illustrated in FIG. 1 is a hair dryer comprising a tubular casing 1 provided with a handle 7 disposed transversely to the casing 1. The casing 1 contains ventilation means represented by a motor-fan group 4 (fig.3) , intended to draw air inside the housing from an air inlet 2. The sucked air is then directed to an air outlet 3, possibly being previously heated by an electric heating element placed inside the housing, between the electric motor and fan 4 assembly and the air outlet 3. The air outlet end of the device can be fitted with various accessories such as nozzles, diffusers, brushes or combs for drying and / or shaping the hairstyle.
La poignée 7 reçoit les câbles d'alimentation électrique qui sont connectés aux composants électriques (moteur, élément chauffant) du boîtier 1 via des moyens de commande et de réglage situés dans la poignée 7.The handle 7 receives the electrical supply cables which are connected to the electrical components (motor, heating element) of the housing 1 via control and adjustment means located in the handle 7.
Les moyens de commande comportent, tel que visible aux figures 1 à 3, deux curseurs de réglage latéraux, respectivement un curseur de réglage de la température 9 et un curseur de réglage de la vitesse 10. Ces curseurs se déplacent par coulissement le long de la poignée, par rapport à des repères visibles dans une fenêtre 8 du boîtier, chaque curseur 9,10 comportant une pointe 9a, 10a d'indication venant en vis-à-vis avec un repère de la fenêtre 8.The control means comprise, as visible in FIGS. 1 to 3, two lateral adjustment cursors, respectively a temperature adjustment cursor 9 and a speed adjustment cursor 10. These cursors move by sliding along the handle, relative to visible marks in a window 8 of the housing, each cursor 9,10 comprising a tip 9a, 10a of indication coming opposite with a mark of window 8.
Tel que mieux visible en figure 4, le curseur de réglage de la température 9 est solidaire d'une barrette 11 , s'étendant en direction longitudinale de la poignée vers le bas, qui est reliée, par une bride 11a, à un commutateur 14 de réglage de la température. Le commutateur 14 présente plusieurs paires de plots qui sont commutés en ligne par le curseur de réglage de la température 9 pour brancher l'élément chauffant sur plusieurs niveaux de puissance. L'élément chauffant électrique de l'appareil peut être une résistance électrique du type à fil bobiné autour d'un support isolant comportant plusieurs prises reliées au commutateur 14 de manière à diviser la résistance en plusieurs parties pour obtenir différents modes de puissance. Dans l'exemple présenté aux figures, le commutateur 14 commute entre trois modes de puissance correspondant aux repères représentés par 1 ,2,3 dans la fenêtre d'affichage 8.As best seen in Figure 4, the temperature adjustment slider 9 is integral with a bar 11, extending in the longitudinal direction of the handle downwards, which is connected, by a flange 11a, to a switch 14 for adjusting the temperature. The switch 14 has several pairs of pads which are switched online by the temperature adjustment slider 9 to connect the heating element to several power levels. The electrical heating element of the device can be an electrical resistance of the wire type wound around an insulating support comprising several sockets connected to the switch 14 so as to divide the resistance into several parts to obtain different power modes. In the example presented in the figures, the switch 14 switches between three power modes corresponding to the references represented by 1, 2.3 in the display window 8.
Le curseur de réglage de la vitesse d'air 10 est, lui, solidaire d'une barrette 12 parallèle à la barrette 11 , barrette 12 qui est reliée, par une bride 12a, à un commutateur 15 de réglage de la vitesse. Le commutateur 15 est ainsi commuté en ligne par le curseur de réglage de la vitesse 10 et peut établir plusieurs niveaux de vitesse du moto-ventilateur en étant, par exemple relié à un potentiomètre faisant varier la tension d'alimentation du moteur électrique et permettant d'obtenir ainsi plusieurs valeurs pour la vitesse de rotation du moto- ventilateur 4. Dans l'exemple présenté aux figures, le commutateur 15 commute entre trois valeurs de vitesse correspondant aux repères représentés par 0,L,H dans la fenêtre d'affichage 8.The air speed adjustment slider 10 is itself integral with a bar 12 parallel to the bar 11, bar 12 which is connected, by a flange 12a, to a switch 15 for adjusting the speed. The switch 15 is thus switched online by the speed adjustment slider 10 and can establish several levels of speed of the motor-fan by being, for example connected to a potentiometer varying the supply voltage of the electric motor and allowing d thus obtaining several values for the speed of rotation of the fan motor 4. In the example presented in the figures, the switch 15 switches between three speed values corresponding to the marks represented by 0, L, H in the display window 8 .
Les moyens de commande comportent en outre un bouton de commande 21 susceptible de se déplacer par coulissement le long de la poignée 7 pour actionner, tel que mieux visible aux figures 4 à 5, deux interrupteurs 16,17. Pour ceci, le bouton de commande 21 est solidaire d'une tige coudée 22 dont le bras supérieur 23 comporte deux brides 24,25 reliées aux interrupteurs 16,17.The control means further comprise a control button 21 capable of moving by sliding along the handle 7 to actuate, as best seen in Figures 4 to 5, two switches 16,17. For this, the control button 21 is integral with a bent rod 22 whose upper arm 23 has two flanges 24.25 connected to the switches 16.17.
Le bouton de commande 21 permet de choisir entre deux modes de fonctionnement possibles. Pour ceci, lors du coulissement du bouton de commande 21 , le bras 23 commute en ligne les contacts des interrupteurs 16,17 entre deux positions : une première, dite de réglage, mettant en circuit les commutateurs 14,15 avec l'élément chauffant, respectivement le moto- ventilateur afin qu'ils fonctionnent selon le réglage choisi par l'utilisateur, et une deuxième position, dite optimum dans l'exemple présenté aux figures, où les commutateurs 14,15 sont court-circuités, les interrupteurs 16,17 mettant en circuit l'élément chauffant et le moto-ventilateur avec une autre partie du circuit permettant d'obtenir automatiquement un couple unique, de valeur prédéterminée, pour la puissance de l'élément chauffant et la vitesse du moto- ventilateur. Dans une variante, on peut utiliser un seul interrupteur multivoies à la place des deux interrupteurs 16,17.The control button 21 makes it possible to choose between two possible operating modes. For this, during the sliding of the control button 21, the arm 23 switches the contacts of the switches 16,17 online between two positions: a first, called adjustment, putting in circuit the switches 14, 15 with the heating element, respectively the motor-fan so that they operate according to the setting chosen by the user, and a second position, called optimum in the example presented in the figures, where the switches 14, 15 are short-circuited, the switches 16, 17 switching on the heating element and the motor-fan with another part of the circuit making it possible to automatically obtain a single torque, of predetermined value, for the power of the heating element and the speed of the fan motor. Alternatively, a single multi-channel switch can be used in place of the two switches 16,17.
Plus particulièrement selon l'invention, l'appareil comporte un afficheur 19 relié aux moyens de commande qui est apte à indiquer, dans la fenêtre 8, le mode de fonctionnement choisi par l'utilisateur. Pour ceci, il est prévu un mécanisme de commande 20 reliant le bouton de commande 21 à l'afficheur 19. Les composants de ce mécanisme de commande 20 sont mieux visibles en figure 6 et en partie aux figures 4 et 5.More particularly according to the invention, the device comprises a display 19 connected to the control means which is capable of indicating, in window 8, the operating mode chosen by the user. For this, a control mechanism 20 is provided connecting the control button 21 to the display 19. The components of this control mechanism 20 are better visible in FIG. 6 and in part in FIGS. 4 and 5.
En figure 6 on remarque le bouton de commande 21 fixé sur la tige coudée 22 qui comporte deux bras parallèles : supérieur 23 et inférieur 27, s'étendant selon la direction longitudinale de la poignée 7. Le bras supérieur 23 supporte le bouton de commande 21 et se termine, à son extrémité supérieure, par les brides 24,25 d'actionnement des interrupteurs 16,17. Le bras inférieur 27 est guidé en coulissement par une fente longitudinale pratiquée dans la base 32 d'un berceau 31. Le berceau 31 a une forme en U et est monté fixe par rapport à la poignée 7, les deux bras du U formant des parois transversales 33 qui supportent, dans des articulations 30, un levier pivotant 29. Les parois transversales 33 se terminent en partie supérieure par des sections de crémaillère 34.In Figure 6 there is the control button 21 fixed on the bent rod 22 which has two parallel arms: upper 23 and lower 27, extending in the longitudinal direction of the handle 7. The upper arm 23 supports the control button 21 and ends, at its upper end, with the flanges 24,25 for actuating the switches 16,17. The lower arm 27 is guided in sliding by a longitudinal slot made in the base 32 of a cradle 31. The cradle 31 has a U-shape and is mounted fixed relative to the handle 7, the two arms of the U forming walls transverse 33 which support, in articulations 30, a pivoting lever 29. The transverse walls 33 terminate in the upper part by rack sections 34.
Le levier pivotant 29 comporte, en son extrémité inférieure, plusieurs tétons insérés dans une rainure 28 du bras inférieur 27 et il se termine, en sa partie supérieure par deux fourches 37. La rainure 28 présente un chemin de came qui imprime au levier pivotant 29 un mouvement en rotation lorsque le bras inférieur 27 est poussé en coulissement. Les fourches 37 supportent en pivotement une pièce indicatrice constituée d'une première surface indicatrice 39 et d'une deuxième surface indicatrice 40 reliées et formant un angle droit entre elles. Chaque surface indicatrice porte, sur sa face externe, une indication imprimée sous forme d'une rangée de repères, ou d'un message, voire d'une coloration ou d'une décoration différente. Dans l'exemple représenté aux figures, sur la première surface indicatrice 39 sont imprimés deux rangées verticales de repères indiquant, d'un côté les repères 1 ,2,3 (relatifs à des valeurs ascendantes de la puissance de l'élément chauffant) et de l'autre 0,L,H (relatifs à des valeurs ascendantes de la vitesse d'air soufflé qui pourraient être, par exemple, zéro, faible et haute), alors que sur la deuxième surface indicatrice 40 est imprimé un message en un mot, par exemple, OPTIMUM. Ces messages correspondent au mode de fonctionnement choisi par l'utilisateur.The pivoting lever 29 has, at its lower end, several pins inserted in a groove 28 of the lower arm 27 and it ends, in its upper part by two forks 37. The groove 28 has a cam path which prints on the pivoting lever 29 a rotating movement when the arm lower 27 is pushed in sliding. The forks 37 pivotally support an indicator piece constituted by a first indicator surface 39 and a second indicator surface 40 connected and forming a right angle between them. Each indicator surface carries, on its external face, a printed indication in the form of a row of markers, or a message, or even a different coloring or decoration. In the example shown in the figures, on the first indicating surface 39 are printed two vertical rows of marks indicating, on one side the marks 1, 2,3 (relating to ascending values of the power of the heating element) and on the other 0, L, H (relating to ascending values of the speed of the blown air which could be, for example, zero, low and high), while on the second indicating surface 40 is printed a message in one word, for example, OPTIMUM. These messages correspond to the operating mode chosen by the user.
Les deux surfaces indicatrices sont reliées en leurs extrémités par deux secteurs dentés 35 portant chacun un tourillon 36 autour duquel tournent les fourches 37 du levier pivotant 29. Les secteurs dentés 35 sont en arc de cercle de centre situé dans l'intersection des deux surfaces indicatrices. Les dentures des secteurs dentés 35 s'engrènent avec celles des sections de crémaillère 34 des parois transversales 33, de manière à ce que lorsque le levier pivotant 29 tourne, il entraîne en mouvement la pièce indicatrice faisant apparaître, à côté du bouton poussoir 21 , soit la première surface indicatrice 39, soit la deuxième surface indicatrice 40. Les indications portées par ces surfaces indicatrices apparaissent à travers une même fenêtre 8 qui est transparente informant ainsi du mode de fonctionnement qui a été activé.The two indicator surfaces are connected at their ends by two toothed sectors 35 each carrying a pin 36 around which the forks 37 of the pivoting lever 29 rotate. The toothed sectors 35 are in an arc of a center circle situated in the intersection of the two indicator surfaces . The teeth of the toothed sectors 35 mesh with those of the rack sections 34 of the transverse walls 33, so that when the pivoting lever 29 rotates, it drives in movement the indicator piece showing, next to the push button 21, either the first indicator surface 39 or the second indicator surface 40. The indications carried by these indicator surfaces appear through the same window 8 which is transparent thus informing the operating mode which has been activated.
En fonctionnement, l'utilisateur commence par actionner le bouton de commande 21 pour choisir le mode de fonctionnement voulu. Si le mode choisi est celui représenté aux figures 1 et 4, c'est à dire si les repères 1 ,2,3 et O,L,H sont affichés dans la fenêtre 8, l'utilisateur peut alors faire coulisser les curseurs 9 et 10 pour régler indépendamment, d'une part le niveau de puissance de l'élément chauffant, correspondant à une température voulue de l'air soufflé, et, d'autre part, la valeur de la vitesse de l'air soufflé par l'appareil.In operation, the user begins by actuating the control button 21 to choose the desired operating mode. If the mode chosen is that represented in FIGS. 1 and 4, that is to say if the references 1, 2,3 and O, L, H are displayed in the window 8, the user can then slide the sliders 9 and 10 to independently adjust, on the one hand the power level of the heating element, corresponding to a desired temperature of the air blown, and, on the other hand, the value of the speed of the air blown by the device.
Si, par contre, l'utilisateur souhaite activer le mode de fonctionnement optimum de l'appareil, il fait coulisser le bouton poussoir 21 jusqu'à ce qu'un nouveau message s'affiche dans la fenêtre 8, par exemple celui de la figure 2. A ce moment, l'utilisateur sait avec certitude qu'il n'y a pas de réglage à faire et qu'il peut utiliser le sèche-cheveux fonctionnant selon ce mode de réglage automatique prédéterminé pour obtenir un séchage rapide et une bonne mise en forme de la chevelure, tout en ayant protégé ses cheveux. Lors de tests effectués au laboratoire, il s'est avéré qu'un fonctionnement optimum peut être obtenu pour une température comprise entre 50° et 70°C, de préférence 60°C et une vitesse de l'air comprise entre 35 m3/h et 70 m3/h, de préférence 55 m3/h D'autres variantes de réalisation de l'invention peuvent être envisagées, sans sortir du cadre de ses revendications.If, on the other hand, the user wishes to activate the optimum operating mode of the device, he slides the push button 21 until a new message appears in the window 8, for example that of the figure 2. At this time, the user knows with certainty that there is no adjustment to be made and that he can use the hair dryer operating according to this predetermined automatic adjustment mode to obtain rapid drying and good shaping of the hair, while having protected his hair. During tests carried out in the laboratory, it has been found that optimum operation can be obtained for a temperature between 50 ° and 70 ° C, preferably 60 ° C and an air speed between 35 m 3 / h and 70 m 3 / h, preferably 55 m 3 / h Other alternative embodiments of the invention can be envisaged, without departing from the scope of its claims.
Ainsi, on pourrait remplacer le bouton de commande à coulissement par un bouton poussoir à ressort et, de surcroît, placer la fenêtre transparente 8 dans l'axe de ce bouton poussoir, pour ainsi faire défiler les indications dans le cadre du bouton poussoir. La disposition des interrupteurs serait adaptée en conséquence et l'on pourrait obtenir une construction plus compacte. De la même manière, on peut envisager un mécanisme de commande fonctionnant différemment pour entraîner un pivotement des surfaces indicatrices, par exemple en utilisant un mécanisme à leviers articulés du type bielle-manivelle, à cames ou autre pour transformer le mouvement initial imprimé au bouton de commande en un mouvement de pivotement des surfaces indicatrices autour de leur support.Thus, one could replace the sliding control button with a spring-loaded push button and, moreover, place the transparent window 8 in the axis of this push button, thereby scrolling the indications in the context of the push button. The arrangement of the switches would be adapted accordingly and a more compact construction could be obtained. In the same way, it is possible to envisage a control mechanism operating differently to cause the indicator surfaces to pivot, for example by using a mechanism with articulated levers of the connecting rod-crank type, with cams or the like to transform the initial movement imparted to the button. control in a pivoting movement of the indicator surfaces around their support.
Dans une variante supplémentaire, on pourrait envisager un pilotage électronique du fonctionnement de l'appareil, avec un réglage en continu de la température et de la vitesse du moto-ventilateur. In an additional variant, one could envisage an electronic control of the operation of the device, with a continuous adjustment of the temperature and the speed of the motor-fan.
