Description

APPAREIL PORTATIF DE TRAITEMENT DES CHEVEUX A LA VAPEUR PORTABLE APPARATUS FOR TREATING HAIR WITH STEAM
La présente invention concerne un appareil portatif qui effectue un traitement et/ou une mise en forme de la chevelure en utilisant des moyens de production de la vapeur associés éventuellement à un dispositif de mise en forme prévu pour démêler, coiffer ou retenir les cheveux en relation avec la vapeur.The present invention relates to a portable device that performs a treatment and / or shaping of the hair using steam generating means optionally associated with a shaping device provided for detangling, styling or retaining the hair in relation with steam.
On connaît des appareils réalisant un traitement des cheveux à la vapeur, tels que par exemple décrits dans le document US 5 263 501 , où l'appareil est un fer à friser comportant un boîtier supportant un mandrin comprenant une base conique fixée au boîtier et se prolongeant par une partie cylindrique d'extrémité munie d'orifices de sortie de vapeur périphériques. La base conique reçoit la vapeur d'un générateur appartenant au boîtier, vapeur qui suit ensuite l'axe longitudinal du mandrin en direction de ses ouvertures de sortie. La partie cylindrique est insérée dans un bigoudi sur lequel on a enroulé des cheveux qui sont ensuite traités à la vapeur dans l'état. Cet appareil trouve ses limites déjà dans le fait que le transfert de vapeur se fait à distance de l'orifice de sortie de vapeur du générateur, transfert qui génère des pertes de charge et donc une diminution du débit de vapeur en sortie. Par ailleurs, un tel agencement de sortie de vapeur à distance du générateur est également à l'origine des phénomènes de condensation. De ce fait, mis à part son rendement diminué, il est nécessaire de prévoir un conduit de retour vers le réservoir, ce qui complique la construction de l'appareil. De surcroît, l'eau étant envoyée depuis le réservoir à l'intérieur du générateur par une pompe manuelle, la chambre de vaporisation se trouve souvent noyée, notamment lorsque la personne utilisant l'appareil et désirant un débit de vapeur plus fort, appuie trop souvent sur la gâchette de la pompe. Ceci a pour conséquences un débit de vapeur très variable, mais également des écoulements d'eau qui sont gênants, voire dangereux pour la personne utilisant l'appareil.There are known apparatuses for steam hair treatment, such as for example described in US Pat. No. 5,263,501, in which the apparatus is a curling iron having a housing supporting a mandrel comprising a conical base fixed to the housing and extending through a cylindrical end portion provided with peripheral steam outlet ports. The conical base receives steam from a generator belonging to the housing, which vapor then follows the longitudinal axis of the mandrel towards its outlet openings. The cylindrical portion is inserted into a hair curler on which hair has been wrapped which is then steam treated in the state. This device finds its limits already in the fact that the vapor transfer is at a distance from the steam outlet of the generator, transfer which generates pressure losses and thus a decrease in the output steam flow. Moreover, such a remote steam outlet arrangement of the generator is also at the origin of the condensation phenomena. Therefore, apart from its reduced performance, it is necessary to provide a return line to the tank, which complicates the construction of the device. Moreover, the water being sent from the tank inside the generator by a hand pump, the spray chamber is often drowned, especially when the person using the device and desiring a stronger steam flow, too much support often on the trigger of the pump. This results in a very variable steam flow, but also water flows that are troublesome or even dangerous for the person using the device.
Pour pallier ces désavantages, une solution a été décrite dans le document WO 2004/002262 où l'appareil est une pince à lisser à deux mâchoires articulées de manière élastique à l'une de leurs extrémités. Selon ce document, les moyens qui génèrent de la vapeur forment une structure en sandwich contenue dans l'une des mâchoires. Plus particulièrement, une mâchoire comprend un réservoir contenant le liquide de traitement qui vient imprégner une mèche disposée, elle, en contact avec l'élément chauffant de la mâchoire pour évaporer le liquide qui passe ensuite à travers des orifices prévus à cet effet dans la surface de traitement destinée au contact des cheveux. Arrivant toutefois à générer un débit de vapeur de manière plus stable que l'appareil du document précédent, l'inconvénient principal de cet appareil est que, malgré sa structure assez complexe, le débit de vapeur généré n'est que très faible, notamment inférieur à 2g/min. Or, un traitement des cheveux effectué avec un tel flux de vapeur ne produit pas d'effet observable sur les cheveux qui doivent alors être soumis à un traitement thermique supplémentaire, assez fort pour leur imprimer un certain style, et dont la température très élevée les dessèche fortement et peut les abîmer.To overcome these disadvantages, a solution has been described in WO 2004/002262 where the device is a tweezers smoothing pliers resiliently articulated at one of their ends. According to this document, the means that generate steam form a sandwich structure contained in one of the jaws. More particularly, a jaw comprises a reservoir containing the treatment liquid which impregnates a wick arranged in contact with the heating element of the jaw to evaporate the liquid which then passes through orifices provided for this purpose in the surface. treatment for contact with the hair. Having however managed to generate a steam flow rate in a more stable manner than the apparatus of the preceding document, the main disadvantage of this apparatus is that, despite its rather complex structure, the steam flow rate generated is only very low, in particular lower than at 2g / min. However, a hair treatment performed with such a vapor flow does not produce an observable effect on the hair which must then be subjected to an additional heat treatment, strong enough to print a certain style, and whose very high temperature the dries strongly and can damage them.
Le but de la présente invention est de remédier au moins en partie à ces inconvénients et de proposer un appareil de traitement des cheveux pouvant fournir en continu un apport constant de vapeur qui soit apte à traiter en profondeur et de manière efficace la chevelure, tout en ayant une structure simplifiée et un fonctionnement sécuritaire.The object of the present invention is to remedy at least in part these disadvantages and to provide a hair treatment apparatus that can continuously provide a constant supply of steam that is capable of deeply and efficiently treating the hair, while having a simplified structure and safe operation.
Un autre but de l'invention est un appareil de traitement des cheveux apte à envoyer rapidement un apport contrôlé de vapeur à la chevelure traitée, tout en pouvant le dissocier d'un éventuel apport supplémentaire de chaleur et/ou mécanique de traction et/ou chimique.Another object of the invention is a hair treatment apparatus capable of rapidly sending a controlled supply of steam to the treated hair, while being able to dissociate it from a possible additional supply of heat and / or traction mechanics and / or chemical.
Un autre but de l'invention est un appareil de traitement des cheveux à la vapeur qui soit fiable en fonctionnement, qui soit apte à éviter les phénomènes de condensation, tout en pouvant être réalisé de manière simple et économique.Another object of the invention is a steam hair treatment apparatus which is reliable in operation, which is able to avoid condensation phenomena, while being able to be achieved simply and economically.
Ces buts sont atteints avec un appareil portatif de traitement des cheveux à la vapeur comportant un boîtier comprenant un réservoir de liquide, des moyens d'alimentation en liquide d'un générateur de vapeur comportant une chambre de vaporisation en contact thermique avec un élément chauffant électrique, la chambre de vaporisation communiquant avec un ou plusieurs orifices de distribution de la vapeur en direction d'une mèche de cheveux, du fait que le générateur est alimenté en liquide par une pompe électrique et que le débit de vapeur fourni est supérieur à 5g/min et de préférence compris entre 10g/min et 60g/min.These goals are achieved with a portable hair treatment device at the vapor comprising a housing comprising a liquid reservoir, liquid supply means of a steam generator comprising a vaporization chamber in thermal contact with an electric heating element, the vaporization chamber communicating with one or more dispensing orifices; the steam towards a lock of hair, because the generator is supplied with liquid by an electric pump and the steam flow rate is greater than 5g / min and preferably between 10g / min and 60g / min.
Un tel générateur de vapeur alimenté par une pompe électrique permet de fournir rapidement un débit de vapeur important, constant et en continu à la mèche traitée pour ainsi aboutir à un traitement durable et en profondeur de celle-ci. De par l'utilisation d'une pompe électrique dont le débit maximum fourni est avantageusement calculé pour être asservi à la puissance maximale de chauffe de la chambre de vaporisation, le liquide introduit dans la chambre par la pompe est immédiatement et complètement transformé en vapeur, évitant ainsi un renvoi de gouttes de liquide non vaporisé par les orifices de distribution. De surcroît, un tel appareil est portatif, ce qui permet d'avoir la sortie de la vapeur agencée au plus près des moyens de génération de vapeur du boîtier pour éliminer les phénomènes de condensation, tout en simplifiant la construction de l'appareil et en rendant plus souple son maniement.Such a steam generator powered by an electric pump makes it possible to rapidly provide a large, constant and continuous steam flow rate to the treated wick so as to result in a durable and deep treatment thereof. By the use of an electric pump whose maximum flow rate is advantageously calculated to be slaved to the maximum heating power of the vaporization chamber, the liquid introduced into the chamber by the pump is immediately and completely converted into vapor, thus avoiding a return of drops of non-vaporized liquid through the dispensing orifices. Moreover, such a device is portable, which makes it possible to have the outlet of the steam arranged as close as possible to the steam generation means of the housing to eliminate the phenomena of condensation, while simplifying the construction of the apparatus and making its handling more flexible.
En effet, en effectuant des tests en laboratoire sur des mèches de cheveux soit à l'état naturel, soit enduites de cosmétique, avec un débit de vapeur supérieur à 5g/min, pouvant aller jusqu'à 100g/min, on a constaté que l'effet du traitement était bien visible sur la mèche traitée, car un fort débit de vapeur permettait déjà de bien préparer les cheveux à un traitement ultérieur, par exemple en les nettoyant et en les chargeant uniformément en humidité. Cet effet était maintenu même sur des mèches traitées par la suite avec un dispositif de mise en forme utilisant une action mécanique et/ou de la chaleur, car les cheveux déjà chargés de manière mieux contrôlée en humidité, gardaient d'autant plus longtemps leur mise en forme, avec des résultats remarquables sur leur aspect, notamment la brillance, la couleur, et ceci de manière homogène dans tout leur volume.Indeed, by performing laboratory tests on strands of hair either in the natural state, or coated with cosmetics, with a steam flow rate greater than 5g / min, up to 100g / min, it has been found that the effect of the treatment was clearly visible on the treated wick, since a high flow of steam already made it possible to prepare the hair for further treatment, for example by cleaning and loading them uniformly with moisture. This effect was maintained even on locks subsequently treated with a shaping device using a mechanical action and / or heat, because the hair already loaded in a better controlled moisture, kept all the longer their implementation in shape, with remarkable results on their appearance, especially gloss, color, and this in a homogeneous way throughout their volume.
En effectuant les mêmes tests sur plusieurs types de mèches, il a été constaté que la plage de débit comprise entre 10g/min et 60g/min donnait les meilleurs résultats en termes d'ouvertures des écailles et de charge en humidité du cheveu et ceci pour la plupart des types de cheveux analysés.By performing the same tests on several types of wicks, it was found that the flow rate range between 10g / min and 60g / min gave the best results in terms of scale openings and moisture load of the hair and this for most types of hair analyzed.
Avantageusement, le ou les orifices de distribution sont agencés à l'une des extrémités du boîtier de l'appareil et celui-ci comprend un déflecteur agencé en vis-à-vis du ou des orifices de distribution.Advantageously, or the dispensing orifices are arranged at one end of the housing of the apparatus and the latter comprises a deflector arranged vis-à-vis the or orifices of distribution.
Ce déflecteur fonctionne comme un pare vapeur en étant placé en vis-à-vis de la sortie de vapeur, tout en ménageant un espace permettant le passage d'une mèche de cheveux. Ainsi, ce déflecteur permet, d'une part, de protéger le cuir chevelu de la personne sur laquelle est réalisé le traitement et, d'autre part, de rediriger la vapeur vers le dos de la mèche et ainsi la traiter sur ses deux faces avec une sortie de vapeur située seulement sur un côté de celle-ci.This deflector functions as a vapor barrier being placed vis-à-vis the steam outlet, while providing a space for the passage of a lock of hair. Thus, this deflector makes it possible, on the one hand, to protect the scalp of the person on whom the treatment is carried out and, on the other hand, to redirect the steam towards the back of the wick and thus treat it on both sides with a steam outlet located only on one side of it.
De préférence, la puissance de l'élément chauffant électrique est comprise entre 600W et 1000W.Preferably, the power of the electric heating element is between 600W and 1000W.
Ceci permet d'obtenir une montée rapide en température de la chambre de vaporisation jusqu'à environ 150° C pour arriver à vaporiser, de préférence de manière instantanée, le liquide introduit dans la chambre par la pompe.This provides a rapid rise in temperature of the vaporization chamber to about 150 ° C to happen to vaporize, preferably instantaneously, the liquid introduced into the chamber by the pump.
Avantageusement, le générateur de vapeur comprend un plateau inférieur muni d'un orifice d'amenée de liquide et d'au moins un orifice de sortie de la vapeur produite et un plateau supérieur, la vapeur étant amenée à circuler entre les deux plateaux par au moins un cheminement à chicanes ayant une longueur comprise entre 100mm et 200mm.Advantageously, the steam generator comprises a lower plate provided with a liquid supply orifice and at least one outlet orifice of the steam produced and an upper plate, the steam being circulated between the two plates by minus a baffled path having a length of between 100mm and 200mm.
De tels circuits à chicanes permettent d'augmenter le temps de contact et de faire varier la direction de déplacement du liquide en contact avec la paroi chaude du générateur et améliorent sensiblement le transfert de chaleur lors de l'ébullition. La chambre de vaporisation est ainsi surchauffée, toutes les gouttelettes d'eau emportées par le flux étant évaporées avant d'arriver au niveau des orifices de sortie de vapeur de la chambre.Such baffle circuits make it possible to increase the contact time and to vary the direction of movement of the liquid in contact with the wall generator and substantially improve the heat transfer during boiling. The vaporization chamber is thus superheated, all the droplets of water carried by the stream being evaporated before reaching the level of the steam outlet orifices of the chamber.
De préférence, l'appareil comporte un ou plusieurs conduits reliant la sortie de la chambre de vaporisation à l'orifice ou aux orifices de distribution ayant chacun une longueur inférieure à 3 cm.Preferably, the apparatus comprises one or more conduits connecting the outlet of the vaporization chamber to the orifice or to the dispensing orifices each having a length less than 3 cm.
La chambre de vaporisation est ainsi positionnée au plus près des orifices de distribution ou de sortie de la vapeur, ce qui permet de traiter la mèche de cheveux directement en sortie de la chambre de vaporisation, via un ou plusieurs conduits. Ces conduits de vapeur en sortie de la chambre de vaporisation étant donc de longueur très courte répartissent la vapeur sans qu'il ne puisse se constituer des condensats qui pourraient alors perturber et/ou annuler l'action de la vapeur sur la mèche ou nuire à la facilité d'usage de l'appareil, les condensats pouvant à la limite brûler la personne utilisant l'appareil ou sur laquelle est appliqué le traitement.The vaporization chamber is thus positioned as close as possible to the steam distribution or outlet orifices, which makes it possible to treat the lock of hair directly at the outlet of the vaporization chamber, via one or more conduits. These steam ducts leaving the vaporization chamber therefore being of very short length distribute the vapor without it being possible to form condensates which could then disturb and / or cancel the action of the steam on the wick or damage to the ease of use of the device, the condensates can limit the person using the device or on which the treatment is applied.
Avantageusement, l'appareil comprend un dispositif de réglage pour ajuster le débit de liquide envoyé vers le générateur.Advantageously, the apparatus comprises an adjusting device for adjusting the flow of liquid sent to the generator.
Un tel dispositif de réglage du débit de liquide envoyé par la pompe dans la chambre de vaporisation permet d'adapter le débit de vapeur produit au type de traitement et/ou au type de cheveu traité avec l'appareil.Such a device for adjusting the flow rate of liquid sent by the pump into the vaporization chamber makes it possible to adapt the flow of steam produced to the type of treatment and / or the type of hair treated with the apparatus.
Dans un mode préféré de réalisation de l'invention, l'appareil comporte un dispositif de mise en forme des cheveux comportant au moins une surface de traitement de forme générale allongée venant au contact d'une mèche de cheveux et lesdits orifices de distribution de vapeur sont adjacents au dispositif de mise en forme.In a preferred embodiment of the invention, the apparatus comprises a device for shaping the hair comprising at least one treatment surface of generally elongated shape coming into contact with a lock of hair and said steam distribution orifices. are adjacent to the shaping device.
Par dispositif de mise en forme des cheveux on comprend un dispositif apte à venir au moins temporairement et/ou localement en contact avec les cheveux pour les démêler, les coiffer ou simplement les retenir au contact d'une surface de traitement, tels que par exemple : un peigne, un cylindre imprégné d'un produit de mise en forme, par exemple de coloration, une pince de lissage à bras articulés mobiles ou fixes, un fer à friser à mandrin cylindrique chauffant coopérant éventuellement avec au moins une plaque chauffante en vis-à-vis, une tête de lissage comportant plusieurs surfaces parallèles de traitement côte à côte, etc.The device for shaping the hair comprises a device capable of at least temporarily and / or locally in contact with the hair to disentangle, comb or simply hold them in contact with a treatment surface, such as for example: a comb, a cylinder impregnated with a product for setting form, for example coloring, a smoothing pliers with movable or fixed articulated arms, a curling iron with a cylindrical heating mandrel possibly cooperating with at least one heating plate facing each other, a smoothing head comprising a plurality of parallel surfaces of side-by-side treatment, etc.
La direction de la mise en forme est définie généralement par la surface de traitement de forme générale allongée du dispositif de mise en forme, surface qui traite généralement avec son côté le plus long la largeur d'une mèche. Par un agencement des orifices de distribution au voisinage de la bordure du dispositif de mise en forme, on exclut donc l'arrivée de la vapeur à l'intérieur du dispositif afin de bien séparer la fonction de traitement à la vapeur d'une autre fonction de mise en forme des cheveux, qui peut être, par exemple, un traitement par application de chaleur, et/ou d'une tension ou pression sur les cheveux, et/ou d'un produit de mise en forme de la chevelure, par exemple un agent de fixation etc., pour un meilleur résultat sur la mèche traitée.The direction of the shaping is generally defined by the generally elongate shaped treatment surface of the shaping device, which surface generally treats with its longest side the width of a wick. By an arrangement of the dispensing orifices in the vicinity of the edge of the shaping device, it is therefore excluded the arrival of steam inside the device in order to separate the steam treatment function from another function. for shaping the hair, which may be, for example, a treatment by application of heat, and / or a tension or pressure on the hair, and / or a product for shaping the hair, by example a fixing agent etc., for a better result on the treated lock.
Avantageusement, le cheminement de vapeur se fait via plusieurs orifices uniformément distribués parallèlement à la surface de traitement du dispositif de mise en forme orientant la vapeur dans une direction perpendiculaire à celle de leur mise en forme par ledit dispositif.Advantageously, the steam path is via several orifices uniformly distributed parallel to the processing surface of the forming device orienting the vapor in a direction perpendicular to that of their shaping by said device.
Un cheminement de vapeur arrivant perpendiculairement à la largeur d'une mèche permet ainsi un traitement rapide de la mèche de cheveux et, de surcroît, homogène lorsque l'on distribue la vapeur par des orifices de sortie couvrant la largeur de la mèche.A vapor path arriving perpendicular to the width of a wick thus allows a quick treatment of the lock of hair and, moreover, homogeneous when the steam is distributed through outlet openings covering the width of the wick.
Dans une première variante de réalisation de l'invention, les orifices de distribution sont adjacents au dispositif de mise en forme des cheveux en étant situés en amont de celui-ci. Par « en amont », on entend que, dans l'opération de traitement, une portion de la mèche de cheveux supporte d'abord l'application de la vapeur avant de supporter le traitement de mise en forme.In a first embodiment of the invention, the dispensing orifices are adjacent to the hair shaping device being located upstream thereof. By "upstream" is meant that, in the treatment operation, a portion of the lock of hair first supports the application of steam before supporting the shaping treatment.
Les tests effectués en traitant une mèche de cheveux avec de la vapeur envoyée en amont du dispositif de mise en forme ont montré que la vapeur arrive à ouvrir les écailles du cheveu, le nettoie en profondeur. L'action mécanique effectuée ensuite par le dispositif de mise en forme finit de débarrasser le cheveu des impuretés provenant par exemple d'un éventuel traitement et/ou soin antérieur.Tests carried out by treating a lock of hair with steam sent upstream of the shaping device showed that the steam manages to open the scales of the hair, cleans it in depth. The mechanical action then performed by the shaping device finishes to rid the hair of impurities resulting for example from a possible treatment and / or previous care.
Les tests en laboratoire ont aussi montré que la vapeur envoyée en amont du dispositif de mise en forme lorsque celui-ci comporte un système de distribution de cosmétique, permet de faciliter la pénétration dudit cosmétique à l'intérieur du cheveu, cela conduisant à une meilleure action en profondeur dudit cosmétique.Laboratory tests have also shown that the steam sent upstream of the shaping device when it includes a cosmetic dispensing system, facilitates the penetration of said cosmetic inside the hair, which leads to better in-depth action of said cosmetic.
Il a aussi été constaté que le traitement de la mèche au moyen d'un dispositif réalisant une action thermique, en plus de celle mécanique, après l'application de la vapeur, empêche la déshydratation du cheveu, celui-ci étant préalablement gainé d'une couche humide. Cette gaine est, certes évaporée au moment de l'action de coiffage, mais en lieu et place de l'eau contenue au cœur du cheveu qui est ainsi protégé de toute déshydratation liée à l'application d'un dispositif de mise en forme chaud.It has also been found that the treatment of the wick by means of a device performing a thermal action, in addition to the mechanical one, after the application of steam, prevents the dehydration of the hair, the latter being previously sheathed with a wet layer. This sheath is, of course, evaporated at the time of the styling action, but instead of the water contained in the heart of the hair which is thus protected from dehydration related to the application of a hot shaping device .
Enfin, les tests en laboratoire ont aussi montré que la vapeur envoyée en amont du dispositif de mise en forme permet de charger suffisamment le cheveu en humidité pour le protéger d'une déshydratation importante lors de l'action du dispositif de mise en forme qui peut être chauffé à haute température, par exemple 2300C.Finally, the laboratory tests have also shown that the steam sent upstream of the shaping device can sufficiently load the hair in moisture to protect it from significant dehydration during the action of the shaping device that can be heated at high temperature, for example 230 ° C.
Dans une deuxième variante de réalisation de l'invention, lesdits orifices de distribution sont adjacents au dispositif de mise en forme des cheveux en étant situés en aval de celui-ci.In a second variant embodiment of the invention, said orifices distribution are adjacent to the hair shaping device being located downstream thereof.
Par « en aval », on entend que, dans l'opération de traitement, une portion de la mèche de cheveux supporte d'abord le traitement de mise en forme avant de supporter l'application de vapeur.By "downstream" it is meant that, in the treatment operation, a portion of the lock of hair initially supports the shaping treatment before supporting the application of steam.
Les tests effectués avec un appareil réalisé selon cette variante de l'invention ont montré que, après une mise en forme mécanique de la mèche, la vapeur vient réhydrater le cheveu pour compenser la déshydratation liée à l'application sur le cheveu de la surface de traitement chaude d'un dispositif de mise en forme.Tests carried out with an apparatus made according to this variant of the invention have shown that, after mechanical shaping of the wick, the steam rehydrates the hair to compensate for the dehydration associated with the application to the hair of the surface of the hair. hot treatment of a shaping device.
De préférence, le dispositif de mise en forme comprend au moins un élément chauffant électrique en contact thermique avec la surface de traitement.Preferably, the shaping device comprises at least one electric heating element in thermal contact with the treatment surface.
Un tel dispositif comportant son propre élément chauffant, indépendant de celui du générateur de vapeur, permet alors de réaliser une mise en forme durable de la chevelure, par exemple un lissage, un bouclage, un gaufrage de celle-ci. Lorsque l'on applique la vapeur à une mèche de cheveux après la mise en forme par un dispositif réalisant une action thermique, voire, combinée à une action mécanique sur la mèche, la vapeur vient réhydrater le cheveu pour compenser la déshydratation liée à l'application sur le cheveu d'un outil chaud.Such a device comprising its own heating element, independent of that of the steam generator, then makes it possible to form a durable shaping of the hair, for example a smoothing, a looping, an embossing thereof. When the steam is applied to a lock of hair after shaping by a device performing a thermal action, or combined with a mechanical action on the wick, the steam rehydrates the hair to compensate for the dehydration related to the application on the hair of a hot tool.
De préférence, le dispositif de mise en forme comporte des moyens de commande indépendants de ceux de commande de la vapeur.Preferably, the shaping device comprises control means independent of those for controlling the steam.
Ceci permet de bien dissocier les deux fonctions, tout en permettant d'ajuster les paramètres de fonctionnement de chaque fonction indépendamment.This allows to separate the two functions, while allowing to adjust the operating parameters of each function independently.
Avantageusement, le boîtier comprend un corps se prolongeant vers le bas par une poignée, le dispositif de mise en forme étant agencé à l'opposé de la poignée et le cheminement de vapeur sortant par les orifices de distribution est orienté selon la direction longitudinale du corps du boîtier.Advantageously, the housing comprises a body extending downwards by a handle, the shaping device being arranged opposite the handle and the steam path exiting through the dispensing orifices is oriented in the longitudinal direction of the housing body.
Une telle configuration de boîtier assure à la fois une bonne ergonomie en utilisation et un traitement efficace de la chevelure par la vapeur.Such a housing configuration provides both good ergonomics in use and effective treatment of the hair by steam.
Dans un mode préféré de réalisation de l'invention, le dispositif de mise en forme des cheveux comprend deux bras articulés, mobiles dans des directions opposées, comportant chacun une surface de traitement des cheveux, au moins l'un des bras comportant un élément chauffant en contact thermique avec ladite surface de traitement.In a preferred embodiment of the invention, the hair shaping device comprises two articulated arms movable in opposite directions, each having a hair treatment surface, at least one of the arms having a heating element. in thermal contact with said treatment surface.
Un tel dispositif assure un lissage efficace des cheveux, avec une bonne tenue dans le temps.Such a device provides effective smoothing of the hair, with good performance over time.
Avantageusement, le dispositif de mise en forme est agencé de manière amovible par rapport au boîtier de l'appareil.Advantageously, the shaping device is removably arranged relative to the housing of the apparatus.
Ceci permet l'utilisation ambidextre de l'appareil avec un même dispositif, voire avec une pluralité de dispositifs de mise en forme, de manière simple et peu coûteuse.This allows the ambidextrous use of the apparatus with the same device, or even with a plurality of formatting devices, in a simple and inexpensive way.
Ceci permet aussi de distribuer la vapeur seule sans mise en forme antérieure ou ultérieure. Dans ce cas, le pare-vapeur est solidaire du corps de l'appareil et non pas du dispositif de mise en forme.This also allows the steam to be dispensed alone without prior or subsequent shaping. In this case, the vapor barrier is integral with the body of the device and not the shaping device.
De préférence, le liquide contenu dans le réservoir est un produit de traitement.Preferably, the liquid contained in the reservoir is a treatment product.
Par liquide de traitement on comprend tout liquide apte à être vaporisé par le générateur et pouvant ensuite être appliqué sur les cheveux sous forme de vapeur pour en assurer un soin, une mise en forme, une coloration une décoloration, etc. Dans un mode préféré de réalisation de l'invention, ce liquide est l'eau. Dans un autre mode de réalisation de l'invention, l'appareil comprend un réservoir supplémentaire de liquide adjacent au dispositif de mise en forme des cheveux ou appartenant à celui-ci.By treatment liquid is understood any liquid capable of being vaporized by the generator and which can then be applied to the hair in the form of steam to ensure care, shaping, coloring, discoloration, etc. In a preferred embodiment of the invention, this liquid is water. In another embodiment of the invention, the apparatus comprises an additional reservoir of liquid adjacent to or belonging to the hair shaping device.
Ce réservoir supplémentaire peut donc appartenir à l'appareil ou au dispositif de mise en forme et permet d'appliquer à la chevelure un liquide qui ne soit pas forcément vaporisé par le générateur de vapeur de l'appareil, par exemple lors d'une application par contact du liquide provenant du réservoir supplémentaire avec la mèche traitée.This additional reservoir can therefore belong to the apparatus or to the shaping device and makes it possible to apply to the hair a liquid that is not necessarily vaporized by the steam generator of the apparatus, for example during an application by contacting the liquid from the additional reservoir with the treated wick.
Avantageusement, le liquide contenu dans le réservoir supplémentaire est différent du liquide contenu dans le réservoir qui alimente le générateur de vapeur.Advantageously, the liquid contained in the additional reservoir is different from the liquid contained in the reservoir that supplies the steam generator.
Ceci permet d'appliquer un liquide cosmétique, par exemple de mise en forme ou de coloration, en plus du traitement à la vapeur.This makes it possible to apply a cosmetic liquid, for example shaping or coloring, in addition to the steam treatment.
Ainsi, dans le cas où le cosmétique a été déposé avant l'application de la vapeur, la vapeur sert de média de transport du cosmétique pour le faire pénétrer à cœur du cheveu via l'ouverture des écailles, le traitement mécanique qui suit permettant de refermer les écailles et de réaliser une forme de cautérisation du cheveu pour fixer le cosmétique.Thus, in the case where the cosmetic has been deposited before the application of the steam, the steam serves as a transport medium for the cosmetic to make it penetrate to the heart of the hair via the opening of the scales, the following mechanical treatment allowing close the scales and perform a form of cauterization of the hair to fix the cosmetic.
Par ailleurs, dans le cas où le cosmétique a été déposé après le traitement mécanique et thermique du cheveu, la vapeur est utilisée comme média de transport, tout en évitant de soumettre le cosmétique à de très hautes températures et éviter ainsi qu'il ne soit détérioré par la température.Moreover, in the case where the cosmetic has been deposited after the mechanical and thermal treatment of the hair, the steam is used as a transport medium, while avoiding to subject the cosmetic to very high temperatures and thus avoid it being deteriorated by the temperature.

Les figures annexées, sauf la figure 4, représentent un appareil portatif de traitement des cheveux à la vapeur comprenant un boîtier 1 réalisé en matière plastique comportant un corps 2 prolongé vers le bas par une partie allongée formant une poignée 3 recevant un réservoir 4 d'eau amovible dont la paroi supérieure constitue la partie supérieure de la poignée. La partie allongée du boîtier 1 renferme également des moyens d'alimentation 6 (figure 3a) d'un générateur de vapeur 8 contenu dans le corps 2 du boîtier 1. Le générateur de vapeur 8 est constitué par une chambre de vaporisation 10, par exemple instantanée, associée à un élément chauffant électrique 9, ces éléments étant visibles à la figure 3a.The appended figures, except FIG. 4, show a portable apparatus for treating hair with steam, comprising a housing 1 made of plastics material comprising a body 2 extended downwards by an elongate part forming a handle 3 receiving a reservoir 4 of removable water whose upper wall constitutes the upper part of the handle.

Les moyens d'alimentation 6 comprennent notamment une pompe électrique 5, visible à la figure 3a, dont la mise en marche est commandée par un bouton de commande 7. A la figure 3a on peut voir également le circuit reliant la pompe électrique 5 au réservoir 4 et au générateur 8. Ainsi, la pompe électrique 5 comporte un orifice d'admission 16 relié par un premier conduit 17 au réservoir 4 et un orifice de refoulement 18 envoyant l'eau issue du réservoir 4 au travers d'un circuit d'alimentation du générateur de vapeur 8. Plus particulièrement, le circuit d'alimentation du générateur de vapeur 8 comprend un second conduit 19 menant à un embranchement divisant le circuit d'alimentation en une première branche de canalisation 20 reliée à un orifice d'admission 21 dans la chambre de vaporisation 10 du générateur de vapeur 8 et une seconde branche de canalisation 22 reliée au réservoir 4 permettant le refoulement d'une partie d'eau issue de la pompe 5 vers le réservoir 4. La section de passage de la première branche de canalisation 20 est inférieure à celle de la seconde branche de canalisation 22 qui est, elle, réalisée en un tuyau souple, l'appareil comportant par ailleurs un dispositif de réglage 23 du débit d'eau envoyé à l'intérieur du générateur 8. Le dispositif de réglage 23 comprend des moyens pour comprimer le tuyau souple de la seconde branche 22 qui traverse un boîtier cylindrique 25. Plus particulièrement, le dispositif de réglage 23 permet, en tournant un bouton moleté 24, d'actionner un levier coudé interne au boîtier 25, levier qui prend appui sur la surface extérieure du tuyau souple.The supply means 6 include an electric pump 5, visible in Figure 3a, whose start is controlled by a control button 7. In Figure 3a can also be seen the circuit connecting the electric pump 5 to the reservoir 4 and the generator 8. Thus, the electric pump 5 comprises an inlet orifice 16 connected by a first conduit 17 to the reservoir 4 and a discharge orifice 18 sending water from the reservoir 4 through a feed circuit of the steam generator 8. More particularly, the circuit supplying the steam generator 8 comprises a second duct 19 leading to a branch dividing the supply circuit into a first duct branch 20 connected to an inlet orifice 21 in the vaporization chamber 10 of the steam generator 8 and a second pipe branch 22 connected to the tank 4 allowing the discharge of a portion of water from the pump 5 to the tank 4. The passage section of the first pipe branch 20 is smaller than that of the second branch of pipe 22 which is, it, made of a flexible pipe, the apparatus further comprising a device 23 for adjusting the flow of water sent inside the generator 8. The dispositi The adjustment device 23 comprises means for compressing the flexible pipe of the second branch 22 which passes through a cylindrical casing 25. More particularly, the adjustment device 23 makes it possible, by turning a knurled knob 24, to actuate an internal bent lever in the casing 25, lever that bears on the outer surface of the hose.
Lors de la mise en route de la pompe 5 au moyen du bouton de commande 7, celle-ci aspire l'eau du réservoir 4 par le premier conduit 17 et refoule l'eau par le second conduit 19, le flux d'eau envoyé par ce circuit étant alors divisé entre un premier flux faible envoyé vers le générateur 8 et un flux plus important envoyé vers le réservoir. Pour augmenter le flux d'eau envoyé vers le générateur 8, on tourne le bouton 24 pour comprimer le tuyau de retour vers le réservoir 4.When the pump 5 is turned on by means of the control knob 7, the latter sucks the water from the tank 4 through the first conduit 17 and delivers the water through the second conduit 19, the flow of water sent by this circuit being then divided between a first weak stream sent to the generator 8 and a larger flow sent to the tank. To increase the flow of water sent to the generator 8, the knob 24 is rotated to compress the return pipe to the tank 4.
Plus particulièrement selon l'invention et tel que mieux visible à la figure 3b, la chambre de vaporisation 10 comporte un compartiment clos réalisé entre un plateau inférieur 50 de forme générale rectangulaire et un plateau supérieur (non représenté pour plus de clarté), les deux plateaux étant fixés ensemble aux quatre coins par des vis 52. Un joint 51 périphérique en silicone situé entre les deux plateaux assure l'étanchéité à l'intérieur de la chambre de vaporisation 10. Le plateau inférieur 50 est muni de plusieurs reliefs constituant des chicanes qui assurent le cheminement du fluide depuis une entrée d'eau jusqu'aux orifices de sorties de vapeur de la chambre. L'arrivée d'eau à l'intérieur de la chambre de vaporisation 10 se fait par l'orifice d'admission 21 situé en la partie centrale d'une paroi avant 53. Le flux d'eau entrant est divisé, puis les gouttes d'eau et de vapeur sont acheminées par les reliefs du plateau inférieur 50 le long de deux cheminements en labyrinthe symétriques 55 et 56, agencés de part et d'autre de l'axe de la chambre passant par l'orifice d'admission central 21. Les cheminements 55,56 ont une longueur d'environ 150mm chacun pour allonger la zone de chauffage de la chambre permettant la transformation en vapeur de l'eau arrivant dans la chambre de vaporisation 10. Les deux cheminements 55,56 se rejoignent dans une zone tampon 57 située juste avant une paroi de fond 54 de la chambre. La zone tampon 57 forme une chambre de distribution pour la vapeur sortant par des ouvertures 58. Dans l'exemple représenté, cinq ouvertures 58 sont pratiquées sur la paroi de fond 54 et débouchent, via cinq tubulures internes réalisées en une seule pièce avec la chambre, dans cinq conduits 14. Chaque conduit 14 est fixé, à l'une de ses extrémités, de manière étanche à la sortie d'une tubulure et il présente, à l'extrémité opposée, une buse de diffusion mise en correspondance, elle avec un orifice de distribution 12 du boîtier de l'appareil. Par ailleurs, les parois internes de la chambre de vaporisation 10 sont recouvertes d'une couche réalisée en un revêtement granuleux destinée à augmenter la surface de contact entre ses parois et les gouttes d'eau à l'intérieur de la chambre et améliorant ainsi la diffusion des gouttes sur la surface chauffante de la chambre. Une telle chambre de vaporisation est apte à produire de manière instantanée de la vapeur sèche à la sortie.More particularly according to the invention and as best seen in Figure 3b, the vaporization chamber 10 comprises a closed compartment formed between a lower plate 50 of generally rectangular shape and an upper plate (not shown for clarity), both trays being secured together at the four corners by screws 52. A peripheral silicone seal 51 located between the two trays provides sealing within the vaporization chamber 10. The lower plate 50 is provided with several reliefs constituting baffles which ensure the flow of the fluid from a water inlet to the steam outlet orifices of the chamber. The water inlet inside the vaporization chamber 10 is through the inlet orifice 21 located in the central part of a front wall 53. The flow of incoming water is divided, then the drops water and steam are conveyed by the reliefs of the lower plate 50 along two symmetrical labyrinth paths 55 and 56, arranged on either side of the axis of the chamber passing through the central inlet orifice. 21. The pathways 55, 56 have a length of approximately 150 mm each to lengthen the heating zone of the chamber allowing steam to be converted into water from the vaporization chamber 10. The two paths 55, 56 meet in a buffer zone 57 located just before a bottom wall 54 of the chamber. The buffer zone 57 forms a distribution chamber for the steam leaving via openings 58. In the example shown, five openings 58 are made on the bottom wall 54 and open via five internal pipes made in one piece with the chamber. in five ducts 14. Each duct 14 is attached, at one of its ends, in a sealed manner at the outlet of a manifold and has, at the opposite end, a diffusion nozzle placed in correspondence, with respect to a dispensing orifice 12 of the housing of the apparatus. Moreover, the internal walls of the vaporization chamber 10 are covered with a layer made of a granular coating intended to increase the contact surface between its walls and the drops of water inside the chamber and thus improving the diffusion of the drops on the heating surface of the chamber. Such a vaporization chamber is able to instantaneously produce dry steam at the outlet.
Le générateur de vapeur 8 est réalisé en un bloc en aluminium ou un alliage d'aluminium ayant une bonne inertie thermique formant un réservoir de calories pour la chambre de vaporisation 10, permettant de vaporiser rapidement l'eau lors de la mise en marche de la pompe. La chambre de vaporisation 10 et l'élément chauffant électrique 9 forment un ensemble monobloc. Dans l'exemple représenté aux figures, l'élément chauffant électrique 9 est une résistance blindée ayant une puissance de 900W. L'alimentation en énergie électrique de l'appareil se fait par un cordon d'alimentation 15, un bouton de mise en marche de l'appareil pouvant commander l'alimentation de l'élément chauffant 9.The steam generator 8 is made of an aluminum block or an aluminum alloy having a good thermal inertia forming a reservoir of calories for the vaporization chamber 10, for quickly vaporizing the water when starting the machine. pump. The vaporization chamber 10 and the electric heating element 9 form a one-piece assembly. In the example shown in the figures, the electric heating element 9 is a shielded resistor having a power of 900W. The electrical power supply of the apparatus is done by a power cord 15, a start-up button of the apparatus that can control the supply of the heating element 9.
Le flux d'eau arrivant à l'intérieur de la chambre de vaporisation 10 est rapidement transformé en vapeur par celle-ci lors de son cheminement le long des chicanes de la chambre de vaporisation instantanée 10. La vapeur sort de la chambre de vaporisation 10 par plusieurs orifices pratiqués sur une paroi de fond de la chambre de vaporisation située à l'opposée de celle recevant l'orifice d'admission 21. Les orifices de sortie de vapeur de la chambre de vaporisation 10 communiquent chacun avec un conduit 14 permettant de distribuer la vapeur à l'extérieur de l'appareil. Ainsi, on peut remarquer à la figure 3b, cinq conduits 14 de faible longueur, par exemple d'environ 1 cm chacun, permettant à la vapeur d'être distribuée immédiatement après la sortie de la chambre de vaporisation 10.The flow of water arriving inside the vaporization chamber 10 is rapidly transformed into vapor by the latter during its path along the baffles of the instantaneous vaporization chamber 10. The vapor exits the vaporization chamber 10 by several orifices provided on a bottom wall of the vaporization chamber located opposite the one receiving the inlet orifice 21. The steam outlet ports of the vaporization chamber 10 each communicate with a conduit 14 allowing distribute the steam to the outside of the appliance. Thus, it can be seen in FIG. 3b, five ducts 14 of short length, for example of approximately 1 cm each, allowing the steam to be distributed immediately after the exit of the vaporization chamber 10.
Tel que mieux visible à la figure 2, le corps 2 du boîtier 1 est fermé, en sa partie inférieure et à l'opposé de la poignée 3, par une face plane 11 comportant plusieurs orifices de distribution de vapeur 12, chaque orifice communiquant avec la sortie d'un conduit 14.As best seen in FIG. 2, the body 2 of the casing 1 is closed, in its lower part and opposite the handle 3, by a flat face 11 having a plurality of steam distribution orifices 12, each orifice communicating with the exit of a conduit 14.
Conformément à un aspect avantageux de l'invention, les orifices de distribution de vapeur 12 sont adjacents à un dispositif de mise en forme 30 des cheveux. Ainsi, la partie supérieure du corps 2 reçoit avantageusement le dispositif de mise en forme 30, ce dernier comprenant au moins une surface de traitement 31 située dans le prolongement, voire en retrait de quelques mm, parallèlement à la face plane 11 du boîtier 1.In accordance with an advantageous aspect of the invention, the steam distribution ports 12 are adjacent to a hair shaping device. Thus, the upper part of the body 2 advantageously receives the shaping device 30, the latter comprising at least one treatment surface 31 located in the extension, or even set back a few mm, parallel to the flat face 11 of the casing 1.
Le dispositif de mise en forme 30 est mieux visible à la figure 4 et il comporte deux bras 33,34 montés articulés autour d'une charnière 35 en étant maintenus en position ouverte ou, dans une variante, en position fermée par un ressort de compression (non visible sur les dessins). On remarque ainsi un bras supérieur 33 comportant, à son extrémité libre, un sabot d'introduction 36 de forme évasée se prolongeant par une surface de traitement 31 plane de forme rectangulaire en contact avec un élément chauffant. Le bras inférieur 34 comporte également, à son extrémité libre, un sabot d'introduction 37 de forme évasée se prolongeant par une surface de traitement 32 plane de forme rectangulaire en contact avec un élément chauffant.The shaping device 30 is better visible in FIG. 4 and it comprises two arms 33, 34 mounted articulated around a hinge 35 while being held in the open position or, in a variant, in the closed position by a spring of compression (not visible on the drawings). There is thus an upper arm 33 having, at its free end, an insertion shoe 36 of flared shape extending by a planar treatment surface 31 of rectangular shape in contact with a heating element. The lower arm 34 also has, at its free end, an introduction shoe 37 of flared shape extending through a planar treatment surface 32 of rectangular shape in contact with a heating element.
Chaque surface de traitement 31 ,32 est formée d'une plaque métallique venant en contact thermique avec un élément chauffant électrique (non visible sur les dessins), qui peut être un élément chauffant résistif, à CTP, à émission infrarouge, etc., qui est placé contre la surface de traitement et à l'intérieur d'un corps 38, respectivement 39 en matière plastique de chaque bras 33,34.Each treatment surface 31, 32 is formed of a metal plate which comes into thermal contact with an electric heating element (not visible in the drawings), which may be a resistive, PTC, infrared emission heating element, etc., which is placed against the treatment surface and inside a body 38, respectively 39 plastic of each arm 33,34.
Chaque élément chauffant électrique peut comporter ses propres moyens de régulation et est alimenté en énergie électrique par un cordon d'alimentationEach electric heating element may have its own regulating means and is supplied with electrical energy by a power cord.
40. L'élément chauffant est prévu pour chauffer les plaques dans une plage de températures allant de 900C à 2300C. Dans une variante, l'appareil comporte un cordon d'alimentation 15 unique permettant de fournir l'énergie électrique au générateur de vapeur 8 et aux plaques chauffantes du dispositif de mise en forme 30. La surface de traitement 31 ,32 est réalisée en un matériau thermiquement conducteur, en étant polie, éventuellement recouverte d'un émail, d'un matériau céramique, d'une couche de verre, etc.40. The heating element is intended to heat the plates in a temperature range from 90 ° C. to 230 ° C. In a variant, the apparatus comprises a single power supply cord 15 for supplying electric energy to steam generator 8 and the heating plates of the shaping device 30. The treatment surface 31, 32 is made of a thermally conductive material, being polished, optionally covered with an enamel, a ceramic material, a layer of glass, etc.
Les bras 33,34 sont ainsi mobiles élastiquement en pivotement autour d'un axe perpendiculaire à la direction longitudinale de leurs surfaces de traitement respectives 31 ,32 entre une position d'ouverture et une position de fermeture. Ainsi, une mèche de cheveux peut être insérée entre les surfaces de traitement 31 ,32 des bras 33,34 lorsque les bras sont en position d'ouverture et elle peut être ensuite soumise à une pression pour venir en contact avec les surfaces de traitement 31 ,32 lorsque les bras sont en position de fermeture, la fermeture pouvant être réalisée par appui sur la surface extérieure des corps 38,39 des bras. Les surfaces de traitement 31 ,32 planes réalisent ainsi un lissage de la mèche avec laquelle elles viennent en contact. Dans une autre variante de réalisation du dispositif de mise en forme 30, les mâchoires sont fermées au repos et l'on vient forcer manuellement l'introduction de la mèche entre les plaques des surfaces de traitement 31 ,32 en tendant la mèche et en la poussant entre les deux plaques à l'aide des sabots d'introduction 36,37. Avantageusement, on peut envisager un système de commande de l'ouverture des plaques pour les écarter suffisamment de manière à simplifier l'introduction de la mèche, l'actionnement pouvant par exemple se faire depuis la poignée de l'appareil ou à proximité de celle-ci.The arms 33,34 are thus elastically movable in pivoting about an axis perpendicular to the longitudinal direction of their respective processing surfaces 31, 32 between an open position and a closed position. Thus, a lock of hair can be inserted between the treatment surfaces 31, 32 of the arms 33, 34 when the arms are in the open position and it can then be subjected to pressure to come into contact with the treatment surfaces. , 32 when the arms are in the closed position, the closure can be performed by pressing on the outer surface of the bodies 38,39 of the arms. The planar processing surfaces 31, 32 thus smooth the wick with which they come into contact. In another variant embodiment of the shaping device 30, the jaws are closed at rest and the insertion of the wick is manually forced between the plates of the treatment surfaces 31, 32 by stretching the wick and pushing between the two plates using the introduction shoes 36,37. Advantageously, it is possible to envisage a system for controlling the opening of the plates to separate them sufficiently in such a way as to simplify the introduction of the wick, the actuation being able for example to be done from the handle of the apparatus or close to that -this.
Selon un aspect avantageux de l'invention, le bras inférieur 34 comporte un déflecteur 42 comportant une paroi 43 agencée en retrait, mais parallèlement à la surface de traitement 32. La paroi 43 forme un pare vapeur protégeant le cuir chevelu de l'action de la vapeur en permettant de renvoyer la vapeur en direction de la mèche de cheveux traitée. Ce renvoi de vapeur a aussi pour avantage d'imprégner la mèche sur ses deux faces en ne disposant que d'une sortie de vapeur unilatérale.According to an advantageous aspect of the invention, the lower arm 34 comprises a deflector 42 having a wall 43 arranged recessed, but parallel to the treatment surface 32. The wall 43 forms a vapor barrier protecting the scalp from the action of the steam to return the steam towards the lock of hair treated. This vapor return also has the advantage of impregnating the wick on both sides by having only a unilateral steam outlet.
Selon un autre aspect avantageux de l'invention, le bras supérieur 33 comporte un support de fixation 45 au corps 2 du boîtier 1 de l'appareil, plus particulièrement une fixation amovible moyennant une vis 46 coopérant avec un orifice fileté dans la partie supérieure du corps 2 de l'appareil. Cette fixation amovible permet alors, en desserrant la vis 46, de passer d'un positionnement tel qu'illustré aux figures, convenant à l'utilisation par une personne droitière, à un autre où le dispositif est tourné de 180° autour de l'axe longitudinal du corps 2 pour l'utilisation de l'appareil par une personne gauchère. Ce dispositif de mise en forme peut être remplacé par un autre, par exemple, comportant un corps d'enroulement cylindrique coopérant avec une pince pivotante d'attache des cheveux, ce dispositif étant alors introduit dans le support de fixation 45 et monté sur le corps 2 du boîtier 1 de l'appareil. La fixation amovible du dispositif de mise en forme 30 permet également l'utilisation de l'appareil de traitement des cheveux à la vapeur seul, sans dispositif de mise en forme monté à son extrémité de sortie de vapeur. La figure 5 illustre une variante de réalisation du déflecteur 42, notamment en le rendant solidaire du corps 2 du boîtier 1 de l'appareil. Plus particulièrement, le déflecteur 42 a une forme générale de diapason comportant une paroi de fond 44 traversée par les orifices de distribution 12, se prolongeant par un coude la reliant à une paroi déflectrice 43 espacée. La paroi déflectrice 43 est située à distance parallèlement à la paroi de fond 44 et se termine par une extrémité recourbée en direction de cette dernière. Un tel déflecteur permet le passage d'une mèche de cheveux entre ses parois parallèles tout en protégeant le cuir chevelu, et assure en même temps le renvoi de la vapeur par la paroi déflectrice en direction de la mèche. Un tel déflecteur peut avantageusement être réalisé en une matière plastique. L'appareil selon la figure 5 peut être utilisé seul pour réaliser le traitement des cheveux, le dispositif de mise en forme 30 pouvant être retiré.According to another advantageous aspect of the invention, the upper arm 33 comprises a fixing support 45 to the body 2 of the housing 1 of the apparatus, more particularly a removable attachment by means of a screw 46 cooperating with a threaded orifice in the upper part of the body 2 of the device. This removable attachment then allows, by loosening the screw 46, to move from a position as illustrated in the figures, suitable for use by a right-handed person, to another where the device is rotated 180 ° around the longitudinal axis of the body 2 for the use of the device by a left-handed person. This shaping device can be replaced by another, for example, having a cylindrical winding body cooperating with a pivoting hair clip, this device then being introduced into the mounting bracket 45 and mounted on the body 2 of the housing 1 of the device. Removable attachment of the shaping device 30 also allows the use of the steam hair treatment apparatus alone, without a shaping device mounted at its vapor outlet end. Figure 5 illustrates an alternative embodiment of the deflector 42, in particular by making it integral with the body 2 of the housing 1 of the device. More particularly, the deflector 42 has a general tuning fork shape with a bottom wall 44 through which the dispensing orifices 12 pass, extending through a bend connecting it to a deflecting wall 43 spaced apart. The deflecting wall 43 is located at a distance parallel to the bottom wall 44 and ends with an end curved towards the latter. Such a deflector allows the passage of a lock of hair between its parallel walls while protecting the scalp, and at the same time ensures the return of steam through the baffle wall towards the wick. Such a deflector may advantageously be made of a plastic material. The apparatus according to Figure 5 may be used alone to perform the hair treatment, the shaper 30 being removable.
En fonctionnement, on met en marche le dispositif de mise en forme 30 des cheveux en appuyant sur un bouton de commande et un témoin lumineux (non représentés sur les dessins) peut indiquer le moment où les plaques chauffantes ont atteint la bonne température. On introduit ensuite une mèche de cheveux à l'intérieur des bras 33,34 du dispositif de mise en forme 30 appliquant un effort de pression sur la mèche, puis on appuie sur le bouton de commande 7, l'appareil commençant à produire de la vapeur de manière instantanée. On déplace ensuite l'appareil le long de la mèche et on réalise un traitement à la vapeur suivi immédiatement d'un lissage par contact avec les surfaces de traitement 31 ,32 du dispositif de mise en forme.In operation, the hair shaping device is turned on by pressing a control button and a light (not shown in the drawings) can indicate when the hotplates have reached the correct temperature. A lock of hair is then introduced into the arms 33, 34 of the shaping device 30 applying a pressing force to the wick, and then the control button 7 is pressed, the apparatus starting to produce hair. steam instantly. The apparatus is then moved along the wick and vapor treatment followed immediately by smoothing by contact with the treatment surfaces 31, 32 of the shaping device.
Du fait que les moyens de commande du dispositif sont indépendants de ceux de l'appareil, celui-ci peut également être utilisé avec les plaques de lissage à la température ambiante ou très faiblement chauffées. Ceci permet notamment de réaliser un nettoyage de la mèche en la débarrassant d'impuretés et en l'hydratant en même temps.Because the control means of the device are independent of those of the device, it can also be used with the smoothing plates at room temperature or very weakly heated. This allows in particular to achieve cleaning of the wick by removing impurities and moisturizing at the same time.
Dans une variante non illustrée sur les dessins, les orifices de distribution de la vapeur sont situés au-dessus du dispositif de mise en forme afin de commencer par un lissage avant le traitement à la vapeur.In a variant not shown in the drawings, the dispensing orifices of the Steam are located above the shaping device to begin with smoothing before steaming.
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
