Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un appareil de coiffure qui est destiné à la mise en forme des cheveux, notamment le lissage, le bouclage, le gaufrage des cheveux d'une personne, utilisant additionnellement de la vapeur.The present invention relates to a hairdressing appliance which is intended for shaping the hair, in particular the smoothing, the wrapping, the embossing of the hair of a person, using additionally steam.

Etat de la technique antérieure :State of the prior art:

On connaît traditionnellement deux types d'appareils de coiffure permettant le lissage ou bouclage ou gaufrage dont les surfaces venant pincer les cheveux sont planes ou courbes ou ondulées et sont chauffées ou chauffantes.Two types of hairdressing apparatus are traditionally known for smoothing or curling or embossing, the surfaces of which pinch the hair are flat or curved or wavy and are heated or heated.

Les appareils du type pinces à lisser ou boucler comportent généralement deux mâchoires pivotantes comprenant chacune une extrémité supportant une surface de traitement, au moins l'une des surfaces de traitement étant chauffée, l'autre étant prévue pour amener les cheveux en contact avec la première, notamment en passant d'une position d'ouverture des mâchoires permettant l'insertion des cheveux à une position de fermeture pour leur mise en contact avec la partie chauffante.The devices of the type pliers to smooth or buckle generally comprise two pivoting jaws each comprising an end supporting a treatment surface, at least one of the treatment surfaces being heated, the other being provided to bring the hair in contact with the first , in particular by passing from an opening position of the jaws allowing the insertion of the hair to a closed position for their contact with the heating part.

L'autre extrémité des mâchoires forme deux demi-poignées faisant office de zone de préhension et permettant de passer de la position d'ouverture à celle de fermeture. Le passage se fait manuellement en pressant les deux demi-poignées articulées de l'appareil l'une vers l'autre pour amener la partie chauffante au contact des cheveux. Le lissage d'une mèche de cheveux s'effectue en déplaçant l'appareil le long de cette mèche, de la racine vers la pointe. Le bouclage d'une mèche de cheveux se fait en enroulant au moins partiellement la mèche autour de la ou des surfaces de traitement et en appliquant de la chaleur pour fixer la boucle principalement en statique.The other end of the jaws form two half-handles acting as a gripping area and to move from the open position to the closing position. The passage is done manually by pressing the two half-handles articulated of the device towards each other to bring the heating part in contact with the hair. Smoothing a lock of hair is done by moving the device along the wick, from the root to the tip. The wrap of a lock of hair is made by at least partially winding the wick around the treatment surface (s) and applying heat to fix the loop mainly in static.

Il est possible, pour améliorer la mise en forme des cheveux, d'utiliser additionnellement de la vapeur projetée sur les cheveux.It is possible, in order to improve the shaping of the hair, to additionally use steam sprayed onto the hair.

Il est connu du document US3934597 un boucleur à cheveux comportant un réservoir d'eau, une chambre de vaporisation, et un compartiment de distribution de la vapeur, ce compartiment comprenant à la fois des chicanes et des orifices de sortie de vapeur. Cet appareil a l'avantage d'être compact. Les chicanes sont introduites pour « prévenir le flux d'eau directement au travers des trous tout en permettant le passage de vapeur, de sorte que l'appareil peut être positionné n'importe comment par l'utilisateur sans qu'il y ait de fuite d'eau. Néanmoins cet appareil ne permet pas d'assurer une sécurité optimale c'est-à-dire n'empêche pas qu'aucune goutte d'eau chaude ne tombe sur le cuir cheveu et le brûle.It is known from the document US3934597 a hair looper with a a water tank, a vaporization chamber, and a steam distribution compartment, this compartment comprising both baffles and steam outlet ports. This device has the advantage of being compact. The baffles are introduced to "prevent the flow of water directly through the holes while allowing the passage of steam, so that the device can be positioned any way by the user without leakage of water. However, this device does not ensure optimal safety that is to say does not prevent any drop of hot water falls on the hair and burns it.

Il est connu aussi du document US3921648 un fer à boucler à vapeur avec dans l'ordre de passage eau-vapeur : un réservoir d'eau, une chambre à chicanes, une chambre de vaporisation principale équipée d'orifices de sortie de vapeur vers les cheveux. Néanmoins les chicanes sont placées à l'entrée de fluide et la chambre de vaporisation est située juste en amont des trous de sortie de vapeur, elle doit donc être chauffée fort pour qu'elle ne génère aucune goutte pulvérisée via ses orifices de sortie sur le cuir chevelu. De plus une forte chauffe entraine des problèmes de caléfaction non souhaités dans l'appareil, ce qui peut avoir pour conséquence de projeter des gouttes d'eau chaude sur le cuir chevelu.It is also known from the document US3921648 a steam loop iron with water-steam order of passage: a water tank, a baffled chamber, a main steam chamber equipped with steam outlet ports to the hair. However, the baffles are placed at the fluid inlet and the vaporization chamber is located just upstream of the steam outlet holes, so it must be heated up so that it does not generate any spray drop via its outlet ports on the scalp. In addition a strong heating causes unwanted heating problems in the device, which can have the effect of projecting drops of hot water on the scalp.

W004002263 divulgue un lisseur vapeur à plaques planes comportant un réservoir d'agent cosmétique, des moyens de transport par action capillaire (feutre) vers une chambre de chauffage comprenant une plaque de vaporisation pour passer la vapeur au travers de la plaque chauffée de lissage. C'est le feutre qui empêche de pulvériser des gouttes d'eau brûlante non souhaitées sur le cuir chevelu, mais cette pièce a une durée de vie faible et se bouche rapidement, et ne permet pas d'assurer un débit continu. De plus, lorsque le feutre est sec, aucune vapeur ne peut plus être produite. W004002263 discloses a flat plate vapor straightener having a cosmetic agent reservoir, capillary action transport means (felt) to a heating chamber comprising a vaporization plate for passing steam through the heated smoothing plate. This is the felt that prevents spraying unwanted drops of hot water on the scalp, but this piece has a short life and closes quickly, and does not ensure a continuous flow. In addition, when the felt is dry, no steam can be produced.

EP1652445 divulgue un lisseur vapeur avec une chambre de génération de vapeur placée sous la plaque de lissage et en communication de fluide avec deux lignes d'orifices de sortie de vapeur de chaque côté de la plaque de lissage. Il existe un risque de pulvériser depuis la chambre des gouttes d'eau brûlante sur le cuir chevelu. EP1652445 discloses a vapor straightener with a steam generation chamber placed under the straightening plate and in fluid communication with two lines of steam outlet ports on each side of the stripper plate. smoothing. There is a risk of spraying hot water from the chamber onto the scalp.

Enfin, FR2921804 et FR2921803 au nom de la demanderesse divulguent des pistolets lisseur vapeur comportant une chambre de vaporisation uniquement équipée de 2 cheminements en labyrinthe symétriques qui se rejoignent dans une chambre de distribution de vapeur commune. Si ce dispositif permet de ne pas pulvériser depuis la chambre des gouttes d'eau brûlante sur le cuir chevelu, il présente en revanche un débit de vapeur assez faible et une durée de vie limitée.Finally, FR2921804 and FR2921803 in the name of the Applicant disclose vapor straightening guns having a vaporization chamber only equipped with 2 symmetrical labyrinth paths which meet in a common steam distribution chamber. If this device does not spray from the chamber drops of hot water on the scalp, it has a rather low steam flow and a limited life.

Exposé de l'invention:Presentation of the invention

Le but de la présente invention est de remédier au moins en partie aux inconvénients précités et de proposer un appareil de traitement des cheveux apte à communiquer rapidement, de manière efficace et uniforme, une humidité contrôlée à la chevelure traitée, tout en pouvant la dissocier d'un éventuel apport supplémentaire de chaleur et/ou effort supplémentaire mécanique de traction et/ou apport supplémentaire de composant chimique.The object of the present invention is to remedy at least in part the aforementioned drawbacks and to provide a hair treatment apparatus capable of communicating quickly, efficiently and uniformly, a controlled humidity to the treated hair, while being able to dissociate it from the hair. a possible additional supply of heat and / or additional mechanical force of traction and / or additional supply of chemical component.

Un autre but de l'invention est un appareil de traitement des cheveux à la vapeur pouvant être utilisé efficacement dans une pluralité de procédés de mise en forme de la chevelure, ayant une excellente résistance au calcaire, ayant un fonctionnement sécuritaire.Another object of the invention is a steam hair treatment apparatus which can be effectively used in a plurality of hair shaping processes, having excellent limestone resistance, having a safe operation.

Un autre but de l'invention est un appareil de traitement des cheveux à la vapeur qui permette de produire un volume d'eau vaporisée important.Another object of the invention is a device for treating hair with steam which makes it possible to produce a large volume of vaporized water.

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.

Un autre but de l'invention est un appareil de traitement des cheveux à la vapeur selon un débit continu qui soit apte à fournir la vapeur de manière homogène à la chevelure, tout en ayant une structure simplifiée, compacte et pouvant être industrialisé pour un faible coût.Another object of the invention is a device for treating hair with steam in a continuous flow that is able to provide the steam homogeneously to the hair, while having a simplified structure, compact and can be industrialized for a low cost.

Un autre but de l'invention est un appareil de traitement des cheveux qui permette un traitement rapide et efficace de la chevelure, tout en étant d'une utilisation aisée et pratique dans l'espace car l'appareil est manipulé par l'utilisateur dans tous les sens.Another object of the invention is a hair treatment apparatus that allows a fast and effective treatment of the hair, while being easy to use and practical in space because the device is manipulated by the user in all the senses.

Ces buts sont atteints avec un appareil de coiffure à vapeur pour mettre en forme les cheveux comprenant une première et une deuxième mâchoire disposées en regard l'une de l'autre, une première surface de traitement portée par la première mâchoire et une deuxième surface de traitement portée par la deuxième mâchoire, les surfaces étant destinées à pincer une mèche de cheveux, un réservoir de liquide, des moyens de vaporisation du liquide en communication de fluide avec le réservoir, des moyens de distribution de la vapeur en communication avec les moyens de vaporisation comportant un ou plusieurs orifices de distribution de la vapeur en direction d'une mèche de cheveux, les moyens de vaporisation comprenant une première chambre de vaporisation formant un volume unique, une deuxième chambre de vaporisation équipée de chicanes, lesdites chambres étant en communication de fluide.These objects are achieved with a steam styling apparatus for shaping hair comprising a first and a second jaw disposed facing each other, a first treatment surface carried by the first jaw and a second surface of treatment carried by the second jaw, the surfaces being intended to pinch a lock of hair, a liquid reservoir, means for vaporizing the liquid in fluid communication with the reservoir, steam distribution means in communication with the means for vaporization comprising one or more steam distribution orifices in the direction of a lock of hair, the vaporization means comprising a first vaporization chamber forming a single volume, a second vaporization chamber equipped with baffles, said chambers being in communication with each other; fluid.

Ainsi la formation de la vapeur s'effectue dans au moins deux chambres différentes, qui permettent efficacement de retenir le tartre non souhaité et d'améliorer la résistance au calcaire sur la durée d'utilisation de l'appareil. La première chambre occupe un premier volume unique, c'est-à-dire un volume défini sans discontinuité ou sans obstacle ou barrière. La deuxième chambre occupe un deuxième volume comprenant des discontinuités introduites par la présence de chicanes pour créer un cheminement changeant pour la vapeur, du type labyrinthe. Ceci apporte une excellente tolérance à l'entartrage. Ceci permet également de vaporiser les éventuelles gouttes d'eau non vaporisées encore, assurant une vaporisation de tout le fluide grâce à la surface d'échange optimisée en valeur (surface agrandie).Thus the formation of steam takes place in at least two different chambers, which effectively retain the undesired scale and improve the limestone resistance over the duration of use of the apparatus. The first chamber occupies a first single volume, that is to say a defined volume without discontinuity or without obstacle or barrier. The second chamber occupies a second volume comprising discontinuities introduced by the presence of baffles to create a changing path for steam, labyrinth type. This provides an excellent tolerance to scaling. This also makes it possible to vaporize any drops of water that are not vaporized yet, ensuring vaporization of all the fluid thanks to the optimized exchange surface. in value (enlarged area).

On entend par chicane tout obstacle ou barrière placée dans la chambre créant des déplacements accidentés de la vapeur, déplacements en zigzag par exemple, réduisant la vitesse de passage dans la chambre, augmentant le contact avec les surfaces des différentes parois de la chambre. Le zigzag de la vapeur, grace aux chicanes se fait suivant l'axe horizontal et vertical : effectivement on peut faire des zigzags de gauche à droite et de haut en bas. Ceci permet également de vaporiser les éventuelles gouttes d'eau non vaporisées encore, assurant une vaporisation de tout le fluide grâce à la surface d'échange optimisée en agencement, c'est-à-dire en agencement en trois dimensions des chicanes.Baffle means any obstacle or barrier placed in the chamber creating uneven movements of the steam, zigzag movements for example, reducing the speed of passage through the chamber, increasing contact with the surfaces of the different walls of the chamber. The zigzag of the steam, thanks to the baffles is made along the horizontal and vertical axis: indeed we can do zigzags from left to right and from top to bottom. This also makes it possible to vaporize any drops of water which are not vaporized further, ensuring vaporization of all the fluid thanks to the optimized exchange surface in arrangement, that is to say in three-dimensional arrangement of the baffles.

On entend par chambre de vaporisation une chambre chauffée par tout moyen de chauffage possible, par exemple une résistance électrique dite à Coefficient de Température Positif (CTP) ou une céramique.A vaporization chamber is understood to mean a chamber heated by any possible heating means, for example an electrical resistance known as a Positive Temperature Coefficient (PTC) or a ceramic.

Selon l'invention, la première chambre de vaporisation est agencée en amont de la deuxième chambre dans le sens du passage de la vapeur. Ainsi on peut considérer que la fonction « création de vapeur » est remplie assez majoritairement dans la première chambre et la fonction « anti-tartre » est remplie assez majoritairement dans la deuxième chambre.According to the invention, the first vaporization chamber is arranged upstream of the second chamber in the direction of the passage of steam. Thus one can consider that the function "steam creation" is filled mostly in the first chamber and the function "anti-scale" is filled mostly in the second chamber.

Selon l'invention le volume interne V1 de la première chambre est supérieur au volume interne V2 de la deuxième chambre, voire au moins deux fois supérieur au volume interne V2 de la deuxième chambre. Un volume V1 élevé permet une vaporisation rapide et un volume V2 plus petit permet la compacité requise, le rapport entre les deux volumes permettant une bonne fonction piège à calcaire.According to the invention, the internal volume V1 of the first chamber is greater than the internal volume V2 of the second chamber, or even at least twice the internal volume V2 of the second chamber. A high volume V1 allows a fast vaporization and a smaller volume V2 allows the required compactness, the ratio between the two volumes allowing a good limestone trap function.

Selon l'invention, les chicanes ou barrières peuvent être réparties parallèles les unes aux autres. Ceci permet le passage de la vapeur selon une géométrie régulière, donc le tartre sera piègé de façon homogène dans la deuxième chambre.According to the invention, the baffles or barriers can be distributed parallel to each other. This allows the passage of steam in a regular geometry, so the tartar will be trapped homogeneously in the second chamber.

Selon l'invention, les chicanes peuvent être au moins au nombre de trois, voire quatre voire cinq. Ceci permet d'accidenter le parcours de la vapeur tout en gardant un encombrement de chambre relativement compact.According to the invention, the baffles can be at least three, or even four or five. This allows to accelerate the course of the steam while maintaining a relatively compact room size.

Selon l'invention, la première chambre peut présenter un volume unique substantiellement parallélépipédique ayant une section choisie parmi une des sections suivantes : section rectangulaire, une section carrée, une section trapézoïdale.... On entend par volume « unique » le fait que la chambre occupe un volume sans accident, sans chicane, sans barrière ou élément à contourner. Ceci permet de fournir un bon compromis entre la compacité et l'efficacité du système vaporisation.According to the invention, the first chamber may have a substantially parallelepipedal single volume having a section chosen from one of the following sections: rectangular section, a square section, a trapezoidal section .... By "single" volume is meant the fact that the room occupies a volume without accident, without baffle, without barrier or element to circumvent. This makes it possible to provide a good compromise between the compactness and the efficiency of the vaporization system.

Selon l'invention les moyens de distribution peuvent être latéraux aux moyens de vaporisation et préférentiellement s'étendre sur sensiblement toute la longueur des moyens de vaporisation. Ceci permet de fournir un bon compromis entre la compacité et l'efficacité du système vaporisation-distribution.According to the invention the distribution means may be lateral to the vaporization means and preferably extend over substantially the entire length of the vaporization means. This makes it possible to provide a good compromise between the compactness and the efficiency of the vaporization-distribution system.

Selon l'invention, alternativement ou additionnellement :

  • la première chambre de vaporisation peut présenter une entrée d'eau sous forme d'un tuyau d'amenée d'eau dont l'orifice est agencé sensiblement au centre de la première chambre.
  • la première chambre de vaporisation peut présenter une entrée d'eau sous forme d'un tuyau d'amenée d'eau dont l'orifice est agencé sensiblement au premier quart de la longueur de la première chambre.
  • la première chambre de vaporisation peut présenter une entrée d'eau sous forme d'un tuyau en matériau comprenant du ou revêtu de PTFE (polytétrafluoroéthylène) connu sous la marque « téflon » ou aussi d'un autre matériau sur lequel le tartre aurait du mal à adhérer ou n'adhère pas.
According to the invention, alternatively or additionally:
  • the first spray chamber may have a water inlet in the form of a water supply pipe, the orifice of which is arranged substantially in the center of the first chamber.
  • the first vaporization chamber may have a water inlet in the form of a water supply pipe, the orifice of which is arranged substantially at the first quarter of the length of the first chamber.
  • the first spray chamber may have a water inlet in the form of a pipe made of material comprising or coated with PTFE (polytetrafluoroethylene) known under the trademark "Teflon" or also of another material on which the scale would have difficulty to join or not to adhere.

Ces dispositions permettent une arrivée d'eau optimisée en ce qu'elle est placée à l'endroit de la chambre où la température est maximale, éloignée le plus possible des parois, permettant ainsi une vaporisation améliorée. L'arrivée est optimisée par le matériau type PTFE ou équivalent, matériau permettant de limiter le dépôt du tartre.These arrangements allow an optimized water inlet in that it is placed at the location of the chamber where the temperature is maximum, as far away as possible from the walls, thus allowing an improved vaporization. The arrival is optimized by the material type PTFE or equivalent, material allowing limit the deposit of tartar.

Ceci permet aussi de limiter l'effet non désiré de caléfaction. Pour mémoire, on appelle caléfaction un phénomène d'isolation thermique d'un liquide par rapport à une surface chauffante ayant atteint une température seuil Ts supérieure à la température d'ébullition du liquide Te. Ce phénomène est dû à la formation d'une couche de vapeur entre la surface chauffante et le liquide, rendant le transfert thermique beaucoup plus lent. La caléfaction est observée quand une goutte d'eau tombe sur une plaque chauffante. La goutte semble rouler sur la surface et ne se vaporise pas immédiatement.This also limits the undesired effect of calefaction. For the record, a phenomenon of thermal insulation of a liquid with respect to a heating surface having reached a threshold temperature T s greater than the boiling temperature of the liquid T e is called a heating phenomenon . This phenomenon is due to the formation of a vapor layer between the heating surface and the liquid, making the heat transfer much slower. Calefaction is observed when a drop of water falls on a hot plate. The drop seems to roll on the surface and does not vaporize immediately.

Selon l'invention, au moins un élément chauffant peut être dédié aux moyens de vaporisation. Ceci permet une vaporisation contrôlable de façon indépendante à toute autre chauffe dans l'appareil de coiffure.According to the invention, at least one heating element can be dedicated to the vaporization means. This allows independently controllable vaporization to any other heater in the hair styling apparatus.

L'élément chauffant peut être agencé contre la plus grande surface extérieure des moyens de vaporisation, préférentiellement placé à l'opposé des orifices de distribution.The heating element may be arranged against the largest outer surface of the vaporization means, preferably placed opposite the dispensing orifices.

Alternativement, dans le cas où l'appareil comporte deux éléments chauffants, ils sont agencés latéralement contre chaque côté des moyens de vaporisation.Alternatively, in the case where the apparatus comprises two heating elements, they are arranged laterally against each side of the vaporization means.

Les éléments chauffants s'étendent plaqués au moins partiellement contre les surfaces latérales des moyens de vaporisation. Avantageusement, un des deux éléments chauffants est plaqué entre une surface latérale extérieure des chambres de vaporisation et une surface extérieure des moyens de distribution de vapeur (une chambre de distribution), ceci permettant d'appliquer de la chaleur aux moyens de vaporisation et de distribution simultanément dans un encombrement réduit.The heating elements extend at least partially plated against the lateral surfaces of the vaporization means. Advantageously, one of the two heating elements is pressed between an outer lateral surface of the vaporization chambers and an outer surface of the steam distribution means (a distribution chamber), this making it possible to apply heat to the vaporization and distribution means simultaneously in a small footprint.

Selon l'invention, le ou les éléments chauffants peuvent être destinés à être régulés par une thermistance. Cette thermistance fonctionne comme sonde de température. Elle peut être une CTN (Coefficient de Température Négatif). La thermistance est branchée pour agir comme une sécurité car elle peut bloquer les moyens de distribution d'eau (pompe) selon la température. D'autres conditions peuvent s'y ajouter comme par exemple la détection de l'ouverture du lisseur qui arrête la pompe. Il est pris comme limite basse de température environ 95°C et comme limite haute de température 130°C, ou bien une gamme plus petite de 105 à 120°C, voire une valeur égale à 110°C.According to the invention, the heating element (s) may be intended to be regulated by a thermistor. This thermistor works as a temperature sensor. It can be a NTC (Negative Temperature Coefficient). The thermistor is connected to act as a safety because it can block the water distribution means (pump) depending on the temperature. Other conditions may be added, such as detection of the opening straightener that stops the pump. It is taken as a low temperature limit of about 95 ° C and as a high temperature limit of 130 ° C, or a smaller range of 105 to 120 ° C, or even a value of 110 ° C.

Selon l'invention, au moins une partie de surface intérieure des moyens de vaporisation présente un revêtement granuleux et/ou est revêtue au moins partiellement d'un agent anti caléfaction. Cet agent peut être parmi les suivants : silicate, Tmate, Ludox, Xylan... Préférentiellement l'agent est appliqué sur les parois de la première chambre, mais peut l'être aussi sur les parois de la deuxième chambre. L'application est faite par vaporisation ou au pinceau...L'état de surface granuleux permet «d'accrocher» le fluide. Ces éléments seuls ou en combinaison permettent de limiter l'effet non désiré de caléfaction.According to the invention, at least a part of the inner surface of the vaporization means has a granular coating and / or is at least partially coated with an anti-caulking agent. This agent can be among the following: silicate, Tmate, Ludox, Xylan ... Preferably the agent is applied to the walls of the first chamber, but can also be applied to the walls of the second chamber. The application is made by spraying or brushing ... The granular surface state allows "to hang" the fluid. These elements alone or in combination can limit the unwanted effect of calefaction.

Selon l'invention, les deux surfaces de traitement des cheveux sont sensiblement complémentaires et de forme plane ou courbée ou gaufrée. Il s'agit alors d'un lisseur, d'un boucleur, respectivement d'un gaufreur.According to the invention, the two hair treatment surfaces are substantially complementary and of planar or curved or embossed shape. It is then a straightener, a looper, respectively a embosser.

The first chamber 71 has a water inlet in the form of a delivery pipe 74 of water whose orifice is arranged approximately in the center of the first chamber 71, illustrated substantially in the middle with respect to its width and substantially at the first quarter of the length of the first chamber 71. The first vaporization chamber 71 has an inlet of water in the form of a pipe made of material comprising PTFE At least one heating element 8 is dedicated to the vaporization means 7. The first mode provides a single heating element for the vaporization means while the second mode provides two elements The heating element 8 is arranged against the larger outer surface of the vaporization means 7 in the first embodiment, preferably placed opposite the dispensing orifices 75. The two heating elements 8 of the second mode are arranged laterally against each side of the vaporization means 7. The heating element or elements 8 are intended to be regulated by a thermistor 10. At least one The inner surface portion of the vaporizing means 7 has a granular coating and / or is at least partially coated with an anti-caulking agent. The two hair treatment surfaces 4,5 are substantially complementary and of planar or curved or embossed shape.

Les chambres sont réalisées en aluminium et peuvent être agencées en deux parties avec deux couvercles : une première partie illustrée en figures 3 et 5 qui vient se poser sur une deuxième partie illustrée en figures 2 et 4, et seront scellées par un joint de silicone. Cette première partie comporte les orifices de distribution de vapeur 75, alors que la deuxième partie sera plaquée contre l'élément chauffant 8. Le bon écrasement de l'élément chauffant et donc son fonctionnement optimal se fait par une lame ressort par exemple. Le capteur de température 10 peut être préférentiellement agencé au dessus de l'arrivée d'eau. L'élément chauffant peut être une thermistance CTP ou une céramique.The rooms are made of aluminum and can be arranged in two parts with two lids: a first part illustrated in Figures 3 and 5 which comes to rest on a second part illustrated in figures 2 and 4 , and will be sealed with a silicone seal. This first part comprises the steam distribution ports 75, while the second part will be pressed against the heating element 8. The good crushing of the heating element and therefore its optimal operation is done by a spring blade for example. The temperature sensor 10 may be preferentially arranged above the water inlet. The heating element may be a PTC thermistor or a ceramic.

Le réservoir de liquide peut être embarqué dans le lisseur qui constitue l'appareil ou peut alternativement être agencé à distance du lisseur dans une base dite déportée comme illustrée en figure 1. Lorsqu'il est à distance, il peut être compris dans une carafe séparée de l'appareil lisseur-boucleur et en communication de liquide avec les moyens de vaporisation de l'appareil.The liquid reservoir may be embedded in the straightener which constitutes the apparatus or may alternatively be arranged at a distance from the straightener in a so-called remote base as illustrated in FIG. figure 1 . When remote, it can be included in a carafe separate from the straightener-looper and in liquid communication with the means of vaporization of the apparatus.

Les pièces où la vaporisation est effective sont les moyens de vaporisation et les moyens de distribution de la vapeur. Les moyens de vaporisation se décomposent en 2 parties distinctes : La première chambre 71 est majoritairement la zone de vaporisation proprement dite : c'est dans cet espace que l'eau est majoritairement transformée en vapeur d'eau. La deuxième chambre de vaporisation 72 est constituée d'un jeu de chicanes 73 qui empêchera à toute goutte d'eau de suivre un chemin direct vers les trous de vaporisation 75 de la chambre de distribution de vapeur 7'. Ceci assurant une qualité de vapeur homogène.The rooms where the vaporization is effective are the vaporization means and the steam distribution means. The vaporization means are decomposed into two distinct parts: The first chamber 71 is mainly the vaporization zone proper: it is in this space that the water is mainly transformed into water vapor. The second vaporization chamber 72 consists of a set of baffles 73 which will prevent any drop of water from following a direct path to the vaporization holes 75 of the steam distribution chamber 7 '. This ensures a homogeneous vapor quality.

Le corps des moyens de vaporisation peut être réalisé par extrusion, il suffit ensuite d'effectuer une reprise sur ce corps pour les trous de vaporisation et pour l'insertion de chaque pièce afin d'assurer l'étanchéité de la chambre. Ces bouchons d'extrémités pouvant être réalisés en fonderie d'aluminium. L'étanchéité entre ces pièces pouvant être réalisée à l'aide d'un joint silicone.The body of the vaporization means can be made by extrusion, it is then sufficient to perform a recovery on this body for the spray holes and for the insertion of each piece to ensure the sealing of the chamber. These end caps can be made in aluminum casting. The seal between these parts can be achieved using a silicone seal.

Comme illustré en figure 8, l'unité portable 100 comprend des moyens de chauffage 41 pour chauffer la première surface de traitement 4. Il peut s'agit d'un élément chauffant 41 qui peut être une thermistance CTP ou une céramique qui est plaquée contre la surface de traitement 4 ou agencée à l'intérieur des éléments comprenant la surface de traitement 4. Les moyens de vaporisation du fluide 7 comportent une chambre de vaporisation 7' et des moyens de chauffage 8 de la chambre de vaporisation 7'. La ou les chambres sont réalisées en aluminium, peuvent comporter des orifices pour la distribution de vapeur 7", et être plaquées en contact direct ou indirect contre l'élément de chauffage 8. Le bon écrasement de l'élément chauffant 8 et donc son fonctionnement optimal se fait par une lame ressort par exemple. Le capteur de température 10 peut être préférentiellement agencé au dessus de l'arrivée d'eau 21. Les moyens de chauffage 8 de la chambre de vaporisation peuvent être au moins un élément chauffant qui peut être une thermistance CTP ou une céramique qui est plaquée contre une des parois ou agencé à l'intérieur de l'élément formant la surface de traitement, ils peuvent être identiques ou séparés des moyens de chauffage de la surface de traitement. Les moyens de distribution de la vapeur (7', 7") présentent une série d'orifices 75 de sortie de vapeur agencés latéralement à la première surface de traitement 4, préférentiellement un peu en retrait de la surface de traitement 4. Alternativement ou additionnellement les moyens de distribution de la vapeur (7', 7") présentent une série d'orifices agencés sur la surface de traitement.As illustrated in figure 8 the portable unit 100 comprises heating means 41 for heating the first treatment surface 4. It may be a heating element 41 which may be a PTC thermistor or a ceramic which is pressed against the treatment surface 4 or arranged inside the elements comprising the treatment surface 4. The fluid evaporation means 7 comprise a vaporization chamber 7 'and heating means 8 of the vaporization chamber 7'. The chamber or chambers are made of aluminum, may have orifices for the distribution of steam 7 ", and be plated in direct or indirect contact against the heating element 8. The good crushing of the heating element 8 and therefore its operation the spring blade, for example, the temperature sensor 10 may preferentially be arranged above the water inlet 21. The heating means 8 of the vaporization chamber may be at least one heating element which may be a PTC thermistor or a ceramic which is pressed against one of the walls or arranged in the inside the element forming the treatment surface, they may be identical or separate from the heating means of the treatment surface. The steam distribution means (7 ', 7 ") have a series of steam outlet orifices 75 arranged laterally to the first treatment surface 4, preferably a little behind the treatment surface 4. Alternatively or additionally the steam distribution means (7 ', 7 ") have a series of orifices arranged on the treatment surface.

Un deuxième mode de réalisation consiste à utiliser deux éléments chauffants et est illustré en figure 7. Selon ce mode, les moyens de vaporisation (2 chambres de vaporisation) sont de volume externe maximum 110x35x12,5mm, intègrent des systèmes de chauffe suffisants pour vaporiser de l'eau par séquence de 10 secondes continue et 10 secondes de repos avec un débit autour de 2,5g/min ± 1g/min, et possèdent un volume interne suffisant pour le stockage du tartre contenu dans au moins 35 litres d'eau dure et de dureté 28°F. Il a été tenu compte de ces contraintes dimensionnelles, il demeure trois points afin de limiter le dépôt de tartre au niveau du tuyau d'arrivée d'eau dans la chambre de vaporisation compacte. Le premier point est la nature du matériau du tuyau au contact de la chambre avec un tuyau en PTFE pour le passage de l'eau au niveau de la chambre de vaporisation. Ce matériau possède une excellente tenue à la température (sup. à 300°C) d'une part et possède un coefficient de friction très faible, d'autre part, ce qui ne facilite pas le dépôt du tartre sur ses parois. Le deuxième point est les diamètres des sections du tuyau d'amenée d'eau. La section interne de ce tuyau doit être importante pour éviter tout bouchage prématuré. Sa section interne doit être égale à au moins 4mm de diamètre. Afin de limiter le transfert de chaleur des parois de la chambre de vaporisation vers l'eau le tuyau possédera une épaisseur d'au moins 1 mm. De plus on adjoindra à la périphérie de ce tuyau une bague de section interne 6mm et externe de 7mm en PPS (polysulfure de phénylène) ce qui limitera encore plus le transfert thermique à la paroi interne du tuyau d'arrivée d'eau. Le troisième point est les distances minimales entre section externe du tuyau d'eau et parois internes de la chambre de vaporisation. Cette distance est fixée par expérience à 1mm. Cette distance permet de limiter le dépôt de tartre dès la section de sortie du tuyau et donc son bouchage prématuré. Cette dernière donnée impose notamment d'avoir une hauteur de chambre de vaporisation au moins égale à 8mm. Les deux chambres de vaporisation ont à titre d'exemple les mesures suivantes : la longueur d'environ 107mm, la largeur d'environ 34mm, la plus grande hauteur d'environ 12,5mm et la plus petite hauteur d'environ 8,5mm, la largueur intérieure de la première chambre est de 16,5mm, la largueur de la chambre de distribution est de 3.5mm, et la largeur des compartiments prévus pour recevoir les éléments chauffants est de 35 mm, le tuyau d'amenée d'eau pénètre à l'intérieur de la chambre de 20mm. Avec les cotes citées, le volume calculé de cette zone « vaporisation » est de 14cm3 environ. La hauteur des moyens de vaporisation est maximisée pour permettre de répondre aux fonctions précitées. Ainsi il reste possible de placer le tuyau en PTFE 14 d'importante section à au moins 1 mm des parois supérieure et inférieure de la première chambre de vaporisation. Une rondelle de PPS est adjointe en entrée de zone de vaporisation. Pour assurer une hauteur maximale à la zone de vaporisation il a été nécessaire de placer les éléments chauffants verticalement sur la tranche. Compte tenu de la géométrie par pan coupé de cette chambre nécessaire à la réduction maximale de son volume externe et de sa faible hauteur (12,5mm), la largeur des éléments chauffants de type céramique ou CTP (préférablement pour des raisons de coût) est limitée. S'il n'y a que le seul élément chauffant (CTP1), la surface d'échange entre l'élément chauffant et la zone de vaporisation (1) est trop faible pour assurer le débit souhaité. Un autre élément chauffant (CTP2) est intégré pour améliorer les capacités thermiques de la chambre et assurer la vaporisation de ce débit. A titre indicatif les CTP choisies sont une CTP1 de dimensions 3,5x10,2x96mm et de Tmax 225°C, une CTP2 de dimensions 3x6,5x74mm et de Tmax 285°C.A second embodiment consists in using two heating elements and is illustrated in figure 7 . According to this mode, the vaporization means (2 vaporization chambers) have a maximum external volume of 110x35x12.5mm, integrate sufficient heating systems to spray water in a sequence of 10 continuous seconds and 10 seconds of rest with a flow rate around of 2.5 g / min ± 1 g / min, and have an internal volume sufficient for storing scale contained in at least 35 liters of hard water and hardness 28 ° F. These dimensional constraints have been taken into account, there are three points in order to limit the deposit of scale at the inlet pipe in the compact vaporization chamber. The first point is the nature of the pipe material in contact with the chamber with a PTFE pipe for the passage of water at the vaporization chamber. This material has excellent resistance to temperature (above 300 ° C) on the one hand and has a very low coefficient of friction, on the other hand, which does not facilitate the deposition of scale on its walls. The second point is the diameters of the sections of the water supply pipe. The internal section of this pipe must be important to prevent premature clogging. Its internal section must be at least 4mm in diameter. In order to limit the heat transfer from the walls of the vaporization chamber to the water the pipe will have a thickness of at least 1 mm. In addition to this will be added to the periphery of this pipe a ring of internal section 6mm and external 7mm PPS (polyphenylene sulfide) which will further limit the heat transfer to the inner wall of the water inlet pipe. The third point is minimum distances between the outer section of the water pipe and the internal walls of the steam chamber. This distance is fixed by experience at 1mm. This distance makes it possible to limit the deposit of scale at the exit section of the pipe and thus its premature plugging. This last data requires in particular to have a vaporization chamber height of at least 8 mm. The two vaporization chambers have as an example the following measures: the length of about 107mm, the width of about 34mm, the greatest height of about 12.5mm and the smallest height of about 8.5mm , the inner width of the first chamber is 16.5mm, the width of the distribution chamber is 3.5mm, and the width of the compartments for receiving the heating elements is 35mm, the water supply pipe penetrates inside the chamber of 20mm. With the quoted dimensions, the calculated volume of this "vaporization" zone is about 14 cm 3 . The height of the vaporization means is maximized to allow the aforementioned functions to be fulfilled. Thus it remains possible to place the PTFE pipe 14 of large section at least 1 mm from the upper and lower walls of the first spray chamber. A PPS washer is attached to the vaporization zone inlet. To ensure maximum height to the vaporization zone it was necessary to place the heating elements vertically on the wafer. Given the cutaway geometry of this chamber necessary for the maximum reduction of its external volume and its low height (12.5mm), the width of the ceramic or CTP type heating elements (preferably for cost reasons) is limited. If there is only the single heating element (CTP1), the exchange surface between the heating element and the vaporization zone (1) is too small to provide the desired flow rate. Another heating element (CTP2) is integrated to improve the thermal capacities of the chamber and ensure the vaporization of this flow. As an indication, the CTPs chosen are a CTP1 of dimensions 3.5x10.2x96mm and Tmax 225 ° C, a CTP2 of dimensions 3x6.5x74mm and Tmax 285 ° C.

Description en fonctionnement :Description in operation:

En fonctionnement, lorsque l'appareil est allumé, l'élément chauffant se met à chauffer les chambres, et un autre élément se met à chauffer les surfaces destinées à venir en contact avec les cheveux. Lorsque le capteur de température atteint une température seuil (150°C par exemple), il libère l'eau par l'actionnement de la pompe 6 actionnée par le moteur 6'. L'eau arrive par le tuyau d'amenée en PTFE (pour ne pas que le tartre y adhère) et tombe dans la première chambre munie de l'agent d'anti-caléfaction et d'un état de surface particulier. L'eau devrait tomber sur la surface la plus chaude car en contact direct avec l'élément chauffant. L'eau est transformée en vapeur et la vapeur produite passe dans la deuxième chambre de vaporisation passe par les chicanes, et arrive dans une troisième chambre (les moyens de distribution) munie d'orifices de distribution de la vapeur. Tout au long de la durée de vie de l'appareil, du tartre va se former, selon la dureté de l'eau utilisée. Ce tartre restera prisonnier dans les chambres de vaporisation: d'abord dans la première chambre, puis, s'il n'est pas piégé dans la première chambre, ensuite dans la deuxième chambre grâce aux chicanes. Le tartre ne sera jamais projeté sur les cheveux de l'utilisateur.In operation, when the device is turned on, the heating element starts to heat the chambers, and another element starts to heat the surfaces. intended to come into contact with the hair. When the temperature sensor reaches a threshold temperature (150 ° C. for example), it releases the water by the actuation of the pump 6 actuated by the motor 6 '. The water arrives through the PTFE supply pipe (so that the scale does not adhere to it) and falls into the first chamber provided with the anti-caulking agent and a particular surface condition. Water should fall on the hottest surface as it is in direct contact with the heating element. The water is transformed into steam and the steam produced passes into the second vaporization chamber passes through the baffles, and arrives in a third chamber (the distribution means) provided with steam distribution orifices. Throughout the life of the device, tartar will form, depending on the hardness of the water used. This tartar will remain prisoner in the vaporization chambers: first in the first chamber, then, if it is not trapped in the first chamber, then in the second chamber thanks to the baffles. Tartar will never be projected onto the user's hair.

En tests, les débits de vapeur constatés sont de l'ordre entre 3 et 4g/min, plutôt environ égaux à 3.5g/min. Par ailleurs, la pompe assure un débit relativement continu, et même relativement constant, de l'ordre de 1 et 5 mL/min, voire entre 3 et 4 préférentiellement égal 3,5mL/min.In tests, the vapor flow rates observed are of the order of between 3 and 4 g / min, more or less equal to 3.5 g / min. Furthermore, the pump provides a relatively continuous flow, and even relatively constant, of the order of 1 and 5 mL / min, or between 3 and 4 preferably equal 3.5 mL / min.
