Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un appareil de coiffure utilisant de la vapeur, destiné à la mise en forme par contact avec les cheveux, notamment au lissage, au bouclage ou au gaufrage des cheveux d'une personne.The present invention relates to a hairdressing apparatus using steam, intended for shaping by contact with the hair, in particular the smoothing, wrapping or embossing of a person's hair.

Etat de la technique antérieureState of the art

On connaît traditionnellement deux types d'appareils de coiffure permettant le lissage ou le bouclage ou le gaufrage dont les surfaces venant pincer les cheveux sont planes ou courbes ou accidentées 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 uneven and are heated or heated.

Les appareils du type pinces à lisser ou boucler ou à gaufrer 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 loop or emboss usually comprise two pivoting jaws each having 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 les surfaces de traitement 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 one another to bring the treatment surfaces 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 prévu dans de tels appareils, pour améliorer la mise en forme des cheveux, d'utiliser additionnellement de la vapeur projetée sur les cheveux.It is provided in such devices, to improve the shaping of the hair, to additionally use steam sprayed on the hair.

US3702616 décrit un appareil de coiffure avec un réservoir interne et un moyen de vaporisation du fluide contenu dans le réservoir. Ce réservoir peut être associé à une pompe commandée par actionnement manuel de l'utilisateur qui choisit ainsi son application de vapeur. Ainsi à la commande manuelle, il se passe quelques secondes pour que la pompe s'amorce, déplace la quantité de fluide et vaporise celui-ci. US3702616 describes a hairdressing apparatus with an internal reservoir and means for vaporizing the fluid contained in the reservoir. This reservoir can be associated with a pump controlled by manual actuation of the user who thus chooses its application of steam. Thus with manual control, it takes a few seconds for the pump to start, move the amount of fluid and vaporize it.

WO2004002262 décrit un fer à friser à vapeur avec réservoir interne pour stocker l'eau à vaporiser, ce réservoir est en contact avec un élément poreux plat amenant le liquide du réservoir en contact avec le bloc de chauffage pour être pulvérisé et avec un parcours de vapeur vers des orifices de sortie placés au niveau de la plaque de traitement du fer. Le réservoir est dans l'appareil et l'élément poreux vise à obtenir un débit constant de vapeur. Néanmoins cet appareil présente l'inconvénient que le débit de vapeur ne peut pas être arrêté, à moins qu'il n'y ait plus de liquide dans le réservoir, ou régulé correctement. WO2004002262 describes a steam curling iron with an internal reservoir for storing the water to be sprayed, this reservoir is in contact with a flat porous element bringing the liquid from the reservoir into contact with the heating block to be sprayed and with a steam path to outlet ports placed at the iron treatment plate. The reservoir is in the apparatus and the porous element aims to obtain a constant flow of steam. However, this apparatus has the disadvantage that the steam flow can not be stopped, unless there is no more liquid in the tank, or regulated properly.

FR2967019 de la demanderesse décrit un lisseur à vapeur dont l'actionnement de la pompe est commandé à la fermeture du lisseur par exemple par un interrupteur magnétique qui détecte la fermeture. WO2013054035 de la demanderesse décrit un lisseur à vapeur à pompe actionnée par fermeture du lisseur. La pompe peut aussi être commandée automatiquement pendant le fonctionnement et notamment en position fermée afin de compenser la trop faible fréquence de fermetures et éviter que la pompe ne se désamorce. Néanmoins, pour ces lisseurs, au début du fonctionnement, l'appareil chauffe les plaques de lissage et la chambre de vaporisation, mais il faut attendre que l'utilisateur commence à l'utiliser et pince l'appareil en position fermée pour que la pompe soit actionnée et que le fluide soit amené dans la chambre de vaporisation. Certains utilisateurs pourraient croire que l'appareil n'est pas fonctionnel car la vapeur ne se forme pas rapidement au premier pincement de l'appareil. FR2967019 of the applicant describes a steam straightener whose actuation of the pump is controlled at the closure of the straightener for example by a magnetic switch which detects the closure. WO2013054035 of the Applicant discloses a steam straightener pump actuated by closing the straightener. The pump can also be controlled automatically during operation and in particular in the closed position to compensate for the too low frequency of closures and prevent the pump from being defused. Nevertheless, for these straighteners, at the beginning of the operation, the apparatus heats the smoothing plates and the vaporization chamber, but it is necessary to wait for the user to start using it and clamp the apparatus in the closed position so that the pump is actuated and that the fluid is brought into the vaporization chamber. Some users might think that the device is not functional because steam does not form quickly at the first pinch of the device.

FR2987242A1 décrit un appareil de coiffure à vapeur selon le préambule de la revendication 1. Aucun appareil de coiffure à vapeur ne comporte des moyens compacts, robustes, automatiques, simples de conception, sécurisés, pouvant fonctionner à des ambiances chaudes, pouvant assurer, rapidement après sa mise sous tension, un débit continu voire constant de vapeur, et ayant une réponse en vapeur très rapide. FR2987242A1 discloses a steam styling apparatus according to the preamble of claim 1. No steam styling apparatus comprises compact, robust, automatic, simple design, secure, operable at hot atmospheres, which can ensure, quickly after powering, a continuous or even constant flow of steam, and having a very fast steam response.

Ces buts sont atteints avec un appareil de coiffure à vapeur destiné à la mise en forme des cheveux selon la revendication 1. Ceci rend transparent pour l'utilisateur l'alimentation en fluide de la chambre pour la première vaporisation pendant le fonctionnement. Ainsi, la vapeur sera formée dès l'application de l'appareil sur la première mèche de cheveux.These objects are achieved with a steam styling apparatus for shaping hair according to claim 1. This makes it transparent for the user to supply fluid to the chamber for the first vaporization during operation. Thus, steam will be formed from the application of the device on the first lock of hair.

Selon l'invention, l'unité de contrôle comporte des moyens pour arrêter l'actionnement desdits moyens de réglage de débit de fluide après une durée référence Dref de fonctionnement. Une fois que l'appareil produit la vapeur par alimentation du fluide commandée par l'utilisateur, les moyens d'actionnement automatique de la pompe peuvent ne plus être utilisés : ce sont des actionneurs mécaniques qui commandent les moyens de réglage de débit de fluide et ceci permet une économie et une simplicité de commande.According to the invention, the control unit comprises means for stopping the actuation of said fluid flow control means after a reference period Dref of operation. Once the apparatus produces the user-supplied fluid supply steam, the automatic pump actuation means may no longer be used: it is mechanical actuators that control the fluid flow control means and this allows economy and simplicity of control.

Selon l'invention, l'unité de contrôle peut comporter des moyens pour calculer la durée référence Dref supérieure ou égale à la durée de remplissage par le fluide de la canalisation de transport du fluide. Cette durée sera prédéterminée pour prendre en compte le plus long intervalle de remplissage de la canalisation quand le débit est le plus bas par exemple. Cette durée peut être supérieure, particulièrement supérieure de plusieurs secondes (10s par exemple) ou particulièrement supérieure de 5% à 30% à la durée réelle de remplissage de la canalisation. Ceci introduit une petite sécurité sans toutefois perdre trop de temps. Ainsi, le principe est que la pompe sera actionnée automatiquement pour que le fluide soit transporté dans toute la canalisation de transport de fluide. La canalisation de transport de fluide est remplie automatiquement et de façon transparente pour l'utilisateur qui n'aura aucune action à remplir.According to the invention, the control unit may comprise means for calculating the reference duration Dref greater than or equal to the duration of filling by the fluid of the fluid transport pipe. This duration will be predetermined to take into account the longest filling interval of the pipe when the flow is the lowest, for example. This duration may be greater, particularly greater than several seconds (10s for example) or particularly greater than 5% to 30% of the actual filling time of the pipe. This introduces a small security without losing too much time. Thus, the principle is that the pump will be actuated automatically so that the fluid is transported throughout the fluid transport line. The fluid transport pipe is filled automatically and transparently for the user who will have no action to complete.

Selon l'invention, l'appareil comprend des moyens de détection de changement de température de la chambre de vaporisation. Plus particulièrement ils permettent de détecter toute baisse de température de la chambre de vaporisation, afin de vérifier que le fluide est arrivé dans la chambre et est vaporisé. Il s'agit bien entendu d'une baisse de température représentative, d'au moins quelques degrés, comprise entre environ 5 et 20°C, par exemple autour de 10°C.According to the invention, the apparatus comprises means for detecting a temperature change of the vaporization chamber. More particularly, they make it possible to detect any drop in temperature of the vaporization chamber, in order to verify that the fluid has arrived in the chamber and is vaporised. This is of course a representative temperature drop of at least a few degrees between about 5 and 20 ° C, for example around 10 ° C.

Selon l'invention, l'unité de contrôle comporte des moyens pour activer lesdits moyens pour actionner, à la fin du préchauffage de la chambre de vaporisation, les moyens de réglage de débit de fluide tant que la durée d'actionnement est inférieure à Dref et que lesdits moyens de détection de changement de température ne détectent pas de baisse de température. Ainsi, l'alimentation automatique du fluide en début de fonctionnement se fait (la pompe est actionnée) pour garantir que toute la canalisation est remplie et que cette alimentation automatique s'arrête dès que son but est atteint, à savoir dès que la vaporisation a réellement commencé.According to the invention, the control unit comprises means for activating said means for actuating, at the end of the preheating of the vaporization chamber, the fluid flow control means as long as the actuation time is less than Dref and that said temperature change detecting means does not detect a temperature drop. Thus, the automatic feeding of the fluid at the beginning of operation is done (the pump is actuated) to ensure that the entire pipe is filled and that this automatic supply stops as soon as its goal is reached, namely as soon as the vaporization has really started.

Selon l'invention, plus particulièrement, l'unité de contrôle peut comporter des moyens pour arrêter l'actionnement desdits moyens de réglage de débit de fluide quand elle compte la durée de fonctionnement égale à Dref. Ceci correspond à un état du réservoir vide et permet non seulement de détecter cet état mais aussi d'arrêter les moyens de réglage de débit de fluide, évitant qu'ils fonctionnent dans le vide.According to the invention, more particularly, the control unit may comprise means for stopping the actuation of said fluid flow control means when it counts the operating time equal to Dref. This corresponds to a state of the empty tank and allows not only to detect this state but also to stop the fluid flow control means, avoiding that they operate in a vacuum.

Selon l'invention, l'unité de contrôle peut comporter des moyens pour désactiver lesdits moyens pour actionner, à la fin du préchauffage de la chambre de vaporisation, les moyens de réglage de débit de fluide si la durée d'actionnement est inférieure à Dref et que lesdits moyens de détection de changement de température détectent une baisse de température. Ceci correspond à un appareil dont la canalisation est déjà au moins partiellement remplie et qui a atteint l'état normal avant la durée de remplissage de la canalisation, permettant de désactiver automatiquement les moyens de réglage du débit dès qu'ils ne sont plus utiles au démarrage.According to the invention, the control unit may comprise means for deactivating said means for actuating, at the end of the preheating of the vaporization chamber, the fluid flow control means if the actuation time is less than Dref and said temperature change detecting means detects a temperature drop. This corresponds to a device whose pipe is already at least partially filled and which has reached the normal state before the filling time of the pipe, to automatically disable the flow control means as soon as they are no longer needed. start-up.

Selon l'invention, l'appareil peut comporter au moins un moyen d'actionnement capable d'émettre un signal d'actionnement vers l'unité de contrôle afin de commander les moyens de réglage de débit de fluide. Ce moyen d'actionnement peut permettre de prendre le relais sur l'unité de contrôle au démarrage qui actionne directement la pompe pour remplir la canalisation de transport de fluide. Ce moyen d'actionnement peut être un bouton ou un capteur de mouvement, d'état, de présence...According to the invention, the apparatus may comprise at least one actuating means capable of transmitting an actuation signal to the control unit in order to control the fluid flow control means. This actuating means can be used to take over the control unit at startup which directly actuates the pump to fill the fluid transport line. This actuation means may be a button or a sensor for movement, state, presence ...

L'appareil de coiffure selon l'invention peut comprendre au moins une première surface de traitement destinée à venir en contact avec les cheveux. Plus précisément, l'appareil de coiffure peut comprendre une première et une deuxième mâchoires disposées en regard l'une de l'autre, la première surface de traitement étant portée par la première mâchoire, une deuxième surface de traitement portée par la deuxième mâchoire, les mâchoires étant reliées par une charnière de sorte à passer d'une position ouverte à une position fermée où les surfaces pincent une mèche de cheveux. Dans ce cas, alternativement ou additionnellement au bouton d'actionnement manuel, les moyens d'actionnement permettant de commander les moyens de réglage de débit de fluide peuvent comprendre des moyens pour détecter la position fermée de l'appareil ou des mâchoires. Une telle détection de fermeture peut être mécanique ou électronique ou magnétique.The hairdressing apparatus according to the invention may comprise at least a first treatment surface intended to come into contact with the hair. More specifically, the hairdressing appliance may comprise a first and a second jaw disposed facing each other, the first treatment surface being carried by the first jaw, a second treatment surface carried by the second jaw, the jaws being connected by a hinge so as to move from an open position to a closed position where the surfaces pinch a lock of hair. In this case, alternatively or additionally to the manual actuation button, the actuating means for controlling the fluid flow control means may comprise means for detecting the closed position of the apparatus or jaws. Such closure detection can be mechanical or electronic or magnetic.

Les moyens de réglage de débit de fluide peuvent comporter une pompe électrique, par exemple une pompe péristaltique, ou une vanne électrique commandée par un moteur relié à l'unité de contrôle.The fluid flow control means may comprise an electric pump, for example a peristaltic pump, or an electric valve controlled by a motor connected to the control unit.

La pompe électrique est commandée par un moteur 6' relié à l'unité de contrôle 13. L'unité de contrôle 13 comprend notamment une mémoire, un timer ou minuterie. L'appareil de coiffure 1 comporte une première mâchoire 2 et une deuxième mâchoire 3 mobiles en pivotement grâce à une charnière 20.The hair styling apparatus 1 for shaping the hair comprises a first treatment surface 4 intended to come into contact with the hair, means for adjusting the fluid flow rate 6, means for vaporizing the fluid 7, steam distribution means 16 for the hair, a control unit 13 for controlling at least the fluid flow control means 6, the fluid flow control means comprising an electric pump or a valve, preferably peristaltic 6.

The hairstyling apparatus 1 comprises a first jaw 2 and a second jaw 3 that can pivotally move by means of a hinge 20.

Le ou les éléments chauffants 8 de la chambre de vaporisation peut être une thermistance par exemple une CTP (Coefficient de Température Positif) ou une céramique. La ou les chambres sont réalisées en aluminium, peuvent comporter des orifices de distribution de vapeur 16, et être plaquées contre l'élément chauffant 8. Le bon écrasement de l'élément chauffant et donc son fonctionnement optimal se fait par une lame ressort (non illustrée) par exemple.The heating element (s) 8 of the vaporization chamber may be a thermistor, for example a PTC (Positive Temperature Coefficient) or a ceramic. The chamber or chambers are made of aluminum, may include steam distribution orifices 16, and 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 (no illustrated) for example.

L'appareil comporte également un moyen de détection de changement de la température 12 de la chambre de vaporisation. En particulier, il peut être un moyen de mesure de la température. Celui -ci peut prendre la forme d'un capteur de température de type thermistance à coefficient de température négatif (CTN) plaquée sous la chambre de vaporisation. Ce détecteur permet de surveiller la température de la chambre de vaporisation et peut être utilisé pour la réguler. Il est utilisé dans la présente invention pour permettre de détecter la baisse ou la chute de température, informant ainsi que le fluide est arrivé dans la chambre de vaporisation et a été vaporisé.The apparatus also comprises a means for detecting a change in the temperature 12 of the vaporization chamber. In particular, it can be a means of measuring the temperature. This may take the form of a thermistor type temperature sensor negative temperature coefficient (CTN) plated under the vaporization chamber. This detector can monitor the temperature of the vaporization chamber and can be used to regulate it. It is used in the present invention to detect the drop or fall in temperature, thereby informing that the fluid has arrived in the vaporization chamber and has been vaporized.

L'usage d'une pompe péristaltique permet d'obtenir un appareil compact, étanche, efficace en amorçage, de forte endurance, pour un débit assez faible, un débit possible constant, insensible au positionnement dans l'espace selon les gestes de l'utilisateur, simple, et fournissant une grande sécurité. La pompe péristaltique 6 est une pompe utilisée pour un liquide contenu dans un tube flexible, il est entraîné par un système de pincement pressant le tube à l'intérieur de la pompe 6. La pompe péristaltique est étanche et le seul élément en contact avec le fluide est le tube flexible. Les risques de fuite sont ainsi limités, et le volume de liquide déplacé est proportionnel à la vitesse de rotation de la pompe. Cette pompe est particulièrement adaptée au dosage, grâce à sa souplesse d'utilisation et sa grande précision. Ainsi la pompe assure un débit relativement continu, et même relativement constant, de l'ordre de 1 à 5 mL/min, voire entre 3 et 4 préférentiellement égal à 3,5mL/min. La pompe est actionnée par un moteur préférentiellement DC. Un patin fixé sur une roue tournant vient écraser un tube en gomme souple, créant ainsi une aspiration vers l'intérieur de la pompe. Le volume de liquide se déplace avec le mouvement du rotor. La maintenance de cette pompe est facile car elle présente une pièce d'usure, le tube, facile à changer.The use of a peristaltic pump makes it possible to obtain a compact, watertight, effective starting device, of high endurance, for a rather low flow rate, a constant possible flow rate, insensitive to the positioning in the space according to the gestures of the user, simple, and providing great security. The peristaltic pump 6 is a pump used for a liquid contained in a flexible tube, it is driven by a clamping system pressing the tube inside the pump 6. The peristaltic pump is sealed and the only element in contact with the fluid is the flexible tube. The risks of leakage are thus limited, and the volume of liquid displaced is proportional to the speed of rotation of the pump. This pump is particularly suitable for dosing, thanks to its flexibility of use and its high accuracy. Thus the pump provides a relatively continuous flow, and even relatively constant, of the order of 1 to 5 mL / min, or between 3 and 4 preferably equal to 3.5 mL / min. The pump is actuated by a motor preferably DC. A pad attached to a rotating wheel crushes a flexible rubber tube, creating suction inside the pump. The volume of liquid moves with the movement of the rotor. The maintenance of this pump is easy because it has a wear part, the tube, easy to change.

L'appareil comprend une première et une deuxième mâchoire 2, 3 disposées en regard l'une de l'autre, la première surface de traitement 4 étant portée par la première mâchoire 2, une deuxième surface de traitement 5 portée par la deuxième mâchoire 3, les mâchoires étant reliées de sorte à passer d'une position ouverte à une position fermée de sorte que les surfaces 4,5 pincent une mèche de cheveux. L'appareil obtenu permet de pincer les cheveux et vaporiser de la vapeur vers les cheveux. Selon l'invention, l'appareil peut comprendre des moyens de chauffage 9 d'au moins une surface de traitement 4,5. La première surface 4 et la deuxième surface 5 de traitement des cheveux peuvent être des surfaces complémentaires plates ou courbes ou ondulées qui, en position fermée de l'appareil, viennent sensiblement en correspondance pour respectivement lisser, boucler ou gaufrer les cheveux. Des moyens de chauffage d'au moins une surface de traitement 4,5 existent et comprennent une résistance et/ou une thermistance (à coefficient de température positif ou CTP......) en contact direct ou indirect avec une des parois de la chambre de vaporisation. La thermistance permet d'assurer une régulation de la chauffe. L'appareil obtenu permet de pincer avec chaleur les cheveux et de vaporiser de la vapeur vers les cheveux. Ceci permet de produire une surface de traitement chauffée ou chaude par conduction de chaleur par exemple, avec contact direct ou indirect. Comme illustré en figure 5, la première des deux conditions dans lesquelles on estime que l'appareil est prêt à l'emploi est la température de consigne de la ou des surfaces de traitement 4, 5.The apparatus comprises a first and a second jaw 2, 3 arranged opposite one another, the first treatment surface 4 being carried by the first jaw 2, a second treatment surface 5 carried by the second jaw 3 , the jaws being connected to move from an open position to a closed position so that the surfaces 4,5 pinch a lock of hair. The device obtained can pinch the hair and vaporize the hair. According to the invention, the apparatus may comprise heating means 9 of at least one treatment surface 4,5. The first surface 4 and the second surface 5 of the hair treatment may be flat or curved or corrugated complementary surfaces which, in the closed position of the apparatus, come substantially in correspondence to respectively smooth, curl or emboss the hair. Means for heating at least one treatment surface 4,5 exist and comprise a resistor and / or a thermistor (with positive temperature coefficient or CTP ......) in direct contact or indirect with one of the walls of the vaporization chamber. The thermistor makes it possible to regulate the heating. The device obtained allows to pinch the hair with heat and steam vapor to the hair. This makes it possible to produce a heated or hot treatment surface by means of heat conduction, for example, with direct or indirect contact. As illustrated in figure 5 , the first of two conditions in which the apparatus is considered ready for use is the set temperature of the treatment surface (s) 4, 5.

Comme illustré en figures 1 et 2, l'appareil peut comprendre deux parties: la première partie étant un appareil portable 10 comprenant les deux mâchoires 2,3, l'unité de contrôle 13, des moyens de vaporisation du fluide 7, et la deuxième partie étant une base 11 déportée de l'appareil portable 10 pouvant comprendre la pompe péristaltique 6 et un réservoir de fluide 19, au moins un cordon de communication de fluide 21 pouvant être prévu entre la base 11 et l'appareil portable 10. Le cordon de communication a une longueur comprise entre 1 et 4m, par exemple égale à 3m. Le diamètre interne du cordon est égal à 1,6mm . Il est possible ainsi de déterminer le volume de fluide nécessaire pour remplir le cordon dans sa totalité. La connaissance du débit, généralement 3,5 g/min (pouvant être variable) permet de savoir la durée de remplissage du cordon. Il est calculé une durée comprise entre 60 et 80 secondes. La durée de référence a été alors fixée à 90 secondes.
Une base déportée contenant un grand réservoir de fluide augmente la capacité de vaporisation et garantit un appareil de traitement relativement léger et maniable. De plus, la pompe ne sera pas soumise à une température élevée car elle est éloignée de la source de chaleur, c'est-à-dire des moyens de vaporisation : le moteur entrainant la pompe ne sera sensiblement pas soumis à une température élevée et le tube de la pompe ne perdra pas en élasticité.As illustrated in Figures 1 and 2 the apparatus may comprise two parts: the first part being a portable apparatus 10 comprising the two jaws 2,3, the control unit 13, means for vaporizing the fluid 7, and the second part being a remote base 11 of the portable apparatus 10 may comprise the peristaltic pump 6 and a fluid reservoir 19, at least one fluid communication cord 21 may be provided between the base 11 and the portable device 10. The communication cord has a length between 1 and 4m, for example equal to 3m. The internal diameter of the cord is equal to 1.6mm. It is thus possible to determine the volume of fluid necessary to fill the cord in its entirety. Knowledge of the flow rate, generally 3.5 g / min (which can be variable) allows to know the duration of filling of the cord. It is calculated a duration between 60 and 80 seconds. The reference time was then fixed at 90 seconds.
A remote base containing a large fluid reservoir increases the spray capacity and ensures a relatively light and manoeuvrable treatment apparatus. In addition, the pump will not be subjected to a high temperature because it is remote from the heat source, that is to say vaporization means: the motor driving the pump will be substantially not subjected to a high temperature and the pump tube will not lose in elasticity.

Alternativement à l'appareil en deux parties, selon l'invention et comme illustré en figure 3, l'appareil peut être plus compact et composé d'une unique pièce : la première mâchoire 2 comprend l'unité de contrôle 13, un réservoir de fluide 19, la pompe péristaltique 6, des moyens de vaporisation du fluide 7 et les moyens de distribution de la vapeur 16. Ceci garantit un appareil de traitement relativement compact. La durée de référence sera alors bien moindre à celle d'un appareil en deux parties.Alternatively to the apparatus in two parts, according to the invention and as illustrated in figure 3 , the apparatus may be more compact and composed of a single piece: the first jaw 2 comprises the control unit 13, a fluid reservoir 19, the peristaltic pump 6, fluid evaporation means 7 and the means of This ensures a relatively compact treatment apparatus. The reference time will then be much less than that of a two-part device.

Selon l'invention, l'appareil comprend des moyens de détection 14, 18 du passage en position d'ouverture et/ou du passage en position de fermeture et l'unité de contrôle peut être programmée pour recevoir depuis les moyens de détection 14, 18 un signal pour commander, en réponse au signal, au moins la pompe péristaltique 6. Ceci permet d'avoir une commande automatique fiable d'au moins un des composants. Ainsi par exemple la vapeur ne sera jamais extraite lorsque l'appareil est en position ouverte. Les moyens de détection peuvent être des moyens capables de détecter uniquement une position ouverte et une position fermée. Ceci simplifie l'usage à deux informations uniquement sans donner d'information d'une position intermédiaire entre celle de fermeture et celle d'ouverture. Les moyens de détection 14,18 du passage en position d'ouverture et/ou du passage en position de fermeture peuvent être des moyens de détection magnétique. Ceci permet que le contact nécessaire pour détecter un changement de position soit magnétique et non mécanique. Ceci réduit les efforts nécessités par l'utilisateur car le contact mécanique n'est plus nécessaire pour détecter le changement de position. La détection se fait aussi sans risque d'absence d'étanchéité. Les moyens de détection 14, 18 magnétique peuvent comprendre un interrupteur magnétique, un capteur à effet Hall. Plus particulièrement, toujours selon l'invention, les moyens de détection magnétique peuvent comprendre un interrupteur magnétique à lame souple (ILS) agencé dans la première mâchoire 2, un aimant agencé dans la deuxième mâchoire 3 de sorte que l'aimant soit actif sur l'interrupteur dans une seule des deux positions. Ceci permet de proposer un appareil compact. Un des éléments -l'aimant- est peu cher, peu encombrant et ne nécessite aucune alimentation particulière, et l'autre élément (ILS) est aussi peu cher, peu encombrant, et pourra être branché simplement en série entre le ou les éléments à commander et l'unité de contrôle. Alternativement aux moyens de détection 14, 18, l'appareil peut, comme illustré en figure 3, comporter un bouton d'actionnement manuel 24 de la vapeur. Ainsi c'est l'utilisateur qui choisit précisément quand il souhaite appliquer de la vapeur.According to the invention, the apparatus comprises detection means 14, 18 of the passage in the open position and / or the passage in the closed position and the control unit can be programmed to receive from the detection means 14, 18 a signal for controlling, in response to the signal, at least the peristaltic pump 6. This allows to have a reliable automatic control of at least one of the components. For example, steam will never be extracted when the appliance is in the open position. The detection means may be means capable of detecting only an open position and a closed position. This simplifies the use of two informations only without giving information of an intermediate position between that of closing and that of opening. The detection means 14, 18 of the passage in the open position and / or the passage in the closed position may be magnetic detection means. This allows the contact necessary to detect a change of position to be magnetic and not mechanical. This reduces the effort required by the user because the mechanical contact is no longer necessary to detect the change of position. The detection is also done without risk of lack of sealing. The magnetic detection means 14, 18 may comprise a magnetic switch, a Hall effect sensor. More particularly, still according to the invention, the magnetic detection means may comprise a flexible blade magnetic switch (ILS) arranged in the first jaw 2, a magnet arranged in the second jaw 3 so that the magnet is active on the switch in only one of the two positions. This makes it possible to propose a compact device. One of the elements - the magnet - is inexpensive, compact and requires no particular power supply, and the other element (ILS) is also inexpensive, compact, and can be simply connected in series between the element or elements to order and the control unit. Alternatively to the detection means 14, 18, the apparatus can, as illustrated in FIG. figure 3 , include a manual actuation button 24 of the steam. So it is the user who chooses precisely when he wants to apply steam.

Dans les deux cas, les moyens de détection 14,18 et le bouton d'actionnement 24 représentent un moyen d'actionnement capable d'émettre un signal vers l'unité de contrôle 13 afin de commander la pompe. Ce moyen d'actionnement est déclenché toujours lors de l'usage de l'appareil, donc volontairement par l'utilisateur lorsqu'il souhaite appliquer de la vapeur. Quand ce moyen d'actionnement est en utilisation, il n'est plus nécessaire alors de faire intervenir, comme selon l'invention, l'unité de contrôle qui, au démarrage, met automatiquement la fonction vapeur en préparation. A chaque pincement de l'appareil ou appui du bouton d'actionnement, la pompe est déclenchée et le fluide alimenté, ce qui garde la fonction vapeur toujours en préparation.In both cases, the detection means 14, 18 and the actuating button 24 represent an actuating means capable of transmitting a signal to the control unit 13 in order to control the pump. This means of actuation is always triggered during the use of the device, so voluntarily by the user when he wants to apply steam. When this actuating means is in use, it is no longer necessary to involve, as in the invention, the control unit which, at startup, automatically puts the steam function in preparation. With each pinch of the device or pressing of the actuating button, the pump is triggered and the fluid supplied, which keeps the steam function always in preparation.

Comme illustré en figure 4, la chambre de vaporisation 7 est séparée en une première chambre de vaporisation 7' est agencée en amont de la deuxième chambre 7" dans le sens du passage de la vapeur. Le volume interne (V1) de la première chambre 7' est supérieur au volume interne (V2) de la deuxième chambre 7". Les chicanes 7'" sont réparties parallèles les unes aux autres dans la deuxième chambre. La première chambre 7' présente un volume substantiellement parallélépipédique ayant une section choisie parmi une des sections suivantes: section rectangulaire, trapézoïdale comme illustré en figure 4. Les moyens de distribution 16 sont agencés latéralement aux moyens de vaporisation du fluide 7 et préférentiellement s'étendent sur sensiblement toute la longueur des moyens de vaporisation 7. Les chambres sont réalisées en aluminium et peuvent comporter des orifices pour la distribution de vapeur 16, 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 12 peut être préférentiellement agencé au dessus de l'arrivée d'eau. 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. La chambre complète de vaporisation a pour dimension approximative une longueur de 83mm, une largeur de 18mm et une hauteur de 5mm. La première chambre 7' présente une entrée d'eau sous forme d'un tuyau 15 d'amenée d'eau dont l'orifice est agencé au premier quart de la longueur de la première chambre ou alternativement au centre de la première chambre (non illustré) et sensiblement au milieu par rapport à sa largeur. La première chambre de vaporisation 7' présente une entrée d'eau sous forme d'un tuyau en matériau comprenant du PTFE, téflon (marque déposée), silicone, POM, PA.

Description en fonctionnement de l'invention:Description in operation of the invention:

En fonctionnement, lorsque l'appareil est allumé, l'utilisateur saisit l'appareil et l'applique pour venir pincer la mèche de cheveux à traiter.In operation, when the device is turned on, the user grasps the device and applies it to pinch the lock of hair to be treated.

En fonctionnement et comme illustré en figure 5, lorsque l'appareil est mis en marche, la chauffe des surfaces de traitement 4,5 est commandée jusqu'à ce que la ou les surfaces de traitement atteigne la température de consigne, qui peut être unique ou choisie par l'utilisateur entre 170°C et 230°C, par exemple par palier de 10°C. La température adéquate des plaques de traitement est une première condition permettant de considérer que l'appareil est prêt à l'emploi.
En parallèle, et ceci concerne tout particulièrement l'invention, lorsque l'appareil est mis en marche, la chauffe de la chambre de vaporisation est commandée jusqu'à atteindre une température de consigne T1, qui peut être comprise entre 130 et 200 °C, par exemple égale à 163°C.
Une fois cette température de consigne atteinte, l'unité de contrôle 13 commande la pompe 6 et déclenche un compteur qui décomptera Dref.
Lorsque la durée de fonctionnement est inférieure à Dref et que la chute de température est détectée, ceci signifie que le fluide est arrivé dans le cycle normal de remplissage à l'intérieur de la chambre de vaporisation et que la canalisation de transport 23 est remplie de fluide, la pompe 6 cesse d'être commandée par l'unité de contrôle 13. La deuxième condition est remplie et l'appareil est considéré comme prêt à l'emploi. Ceci peut éventuellement être communiqué à l'utilisateur par une LED qui clignote ou qui cesse de clignoter.In operation and as illustrated in figure 5 when the apparatus is turned on, the heating of the treatment surfaces 4,5 is controlled until the treatment surface (s) reaches the set temperature, which may be unique or selected by the user between ° C and 230 ° C, for example in steps of 10 ° C. The proper temperature of the treatment plates is a first condition to consider that the device is ready for use.
In parallel, and this relates particularly to the invention, when the apparatus is started, the heating of the vaporization chamber is controlled until a set temperature T1, which can be between 130 and 200 ° C. for example equal to 163 ° C.
Once this set temperature is reached, the control unit 13 controls the pump 6 and triggers a counter which will count down Dref.
When the operating time is less than Dref and the temperature drop is detected, this means that the fluid has arrived in the normal filling cycle inside the vaporization chamber and that the transport pipe 23 is filled with fluid, the pump 6 ceases to be controlled by the control unit 13. The second condition is met and the device is considered ready for use. This can possibly be communicated to the user by an LED which flashes or stops flashing.

Alternativement, lorsque la durée de fonctionnement n'est pas inférieure à Dref ou/et que la chute de température de la chambre de vaporisation n'est pas détectée, alors la commande par l'unité de contrôle de la pompe n'est pas stoppée. Il est vérifié alors si la durée de fonctionnement de la pompe est égale à Dref. Si la durée est inférieure à Dref, alors la pompe continue à être commandée. Si la durée est égale à Dref (ou supérieure ou égale à Dref), alors la pompe cesse d'être commandée par l'unité de contrôle 13. Ceci signifie en effet qu'aucun fluide n'est arrivé dans la chambre de vaporisation bien que la durée nécessaire d'acheminement soit écoulée, ce qui est signe que le réservoir est vide. Ainsi, l'unité de contrôle cesse de commander la pompe et l'information de l'état vide du réservoir peut être communiquée à l'utilisateur via une LED éclairée par exemple ou un écran. Le compteur de l'unité de contrôle est remis à zéro.Alternatively, when the operating time is not lower than Dref and / or the temperature drop of the vaporization chamber is not detected, then the control by the control unit of the pump is not stopped . It is then checked whether the running time of the pump is equal to Dref. If the duration is less than Dref, then the pump continues to be controlled. If the duration is equal to Dref (or greater than or equal to Dref), then the pump ceases to be controlled by the control unit 13. This means that no fluid has arrived in the vaporization chamber. the necessary transit time has elapsed, which indicates that the tank is empty. Thus, the control unit stops controlling the pump and the information of the empty state of the tank can be communicated to the user via an illuminated LED for example or a screen. The counter of the control unit is reset.

Toutes les figures illustrent des modes différents de réalisation sans limiter le nombre d'alternatives dépendant des combinaisons choisies des différents « ensembles de composants » possibles prévus selon l'invention comme revendiquée. Ainsi l'appareil selon l'invention comporte au moins un composant jouant sur au moins un paramètre de fonctionnement de l'appareil et qui pourra être commandé par la CPU à réception du signal représentant l'ouverture ou la fermeture de l'appareil de coiffure.All the figures illustrate different embodiments without limiting the number of alternatives depending on the selected combinations of the different possible "sets of components" provided according to the invention as claimed. Thus the apparatus according to the invention comprises at least one component playing on at least one operating parameter of the apparatus and which can be controlled by the CPU on receipt of the signal representing the opening or closing of the hairdressing apparatus .
