Description

APPAREIL DE COIFFURE A VAPEUR A POMPE COMMANDEE  APPARATUS FOR STEAM HAIR WITH CONTROLLED PUMP
Domaine technique de l'invention Technical 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. Etat de la technique antérieure 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. State 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 from the device towards each other 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 discloses a hairdressing apparatus with an internal reservoir and a means vaporization of 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 discloses 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 of the reservoir into contact with the heating block to be sprayed and with a vapor path to outlet ports 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.
Par conséquent aucun appareil de coiffure produisant de la vapeur ne comporte des moyens compacts, robustes, automatiques, simples de conception, sécurisés, pouvant fonctionner à des ambiances chaudes, pouvant assurer un débit continu voire constant de vapeur, et ayant une réponse en vapeur très rapide. Therefore no hairdressing apparatus producing steam has compact means, robust, automatic, simple design, secure, able to operate in hot environments, can ensure a continuous or even constant flow of steam, and having a very high steam response fast.
Exposé de l'invention: Presentation of the invention

Un autre but de l'invention est de proposer un appareil à vapeur de mise en forme par contact avec les cheveux qui soit efficace et/ou rapide en fonctionnement.

Un autre but de l'invention est de proposer un appareil de mise en forme par contact avec les cheveux, à vapeur et/ou à distribution de fluide, et qui soit étanche en fonctionnement. Another object of the invention is to provide a device for shaping by contact with the hair, steam and / or fluid distribution, and which is sealed in operation.
Un autre but de l'invention est de proposer un appareil à vapeur de mise en forme par contact avec les cheveux qui assure un fonctionnement dans n'importe quelle position de l'appareil. Another object of the invention is to provide a hair-forming shaping apparatus which ensures operation in any position of the apparatus.
Un autre but de l'invention est de proposer un appareil à vapeur de mise en forme par contact avec les cheveux qui permette une utilisation aisée et pratique. Another object of the invention is to provide a hair-forming shaping apparatus which allows easy and convenient use.
Un autre but de l'invention est de proposer un appareil à vapeur de mise en forme par contact avec les cheveux qui soit simple de conception, peu coûteux de conception. Un autre but de l'invention est de proposer un appareil à vapeur de mise en forme par contact avec les cheveux qui soit sécurisé, qui puisse fonctionner dans des ambiances chaudes. Ces buts sont atteints avec un appareil de coiffure à vapeur destiné à la mise en forme des cheveux comprenant un réservoir de fluide; une chambre de vaporisation du fluide avec au moins une entrée de fluide et au moins une sortie de vapeur à destination des cheveux ; une canalisation de transport du fluide entre le réservoir et l'entrée de la chambre de vaporisation, l'extrémité de cette canalisation étant agencée au moins partiellement à l'intérieur de ladite chambre; des moyens de réglage de débit de fluide actifs sur la canalisation ; une unité de contrôle pour commander au moins les moyens de réglage de débit de fluide ; 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; l'unité de commande comportant un compteur pour décompter une durée de décompte prédéterminée D1 et des moyens de compensation de non actionnement des moyens de réglage de débit pour, à la fin du décompte D1 sans réception du signal d'actionnement, commander automatiquement pendant une durée momentanée prédéterminée d1 les moyens de réglage de débit. Another object of the invention is to provide a hair contact shaping apparatus which is simple in design and inexpensive in design. Another object of the invention is to provide a safe shaping device for hair shaping, which can operate in hot environments. These objects are achieved with a steam styling apparatus for shaping hair including a fluid reservoir; a fluid vaporization chamber with at least one fluid inlet and at least one vapor outlet for the hair; a pipe for transporting the fluid between the tank and the inlet of the vaporization chamber, the end of this pipe being arranged at least partially inside said chamber; fluid flow control means active on the pipe; a control unit for controlling at least the fluid flow control means; at least one actuating means capable of transmitting an actuation signal to the control unit for controlling the flow control means; the control unit comprising a counter for counting a predetermined counting time D1 and means for compensating the non-actuation of the flow control means for, at the end of the countdown D1 without receiving the actuating signal, automatically controlling during a predetermined momentary duration d1 of the flow control means.
Pour une efficacité de vaporisation, l'extrémité de canalisation de transport de fluide depuis le réservoir vers la chambre de vaporisation rentre dans la chambre de vaporisation. Cette extrémité de canalisation chauffée est toujours conservée remplie de fluide par le biais de cette commande du microcontrôleur, ceci permettant un débit continu et une commande réactive à la demande de fabrication de vapeur. En effet, par la chaleur et la pression, l'eau présente dans cette extrémité est « propulsée » dans la chambre de vaporisation et la canalisation se retrouve alors vide de fluide, ce qui pourrait désamorcer les moyens de réglage de fluide. La commande momentanée des moyens de réglage de débit de fluide permet de remplir l'extrémité de la canalisation de fluide. On entend par commande momentanée une commande d'une durée substantielle de quelques secondes. Selon l'invention, l'unité de commande, à la fin du décompte D1 sans réception du signal d'actionnement, a des moyens pour commander automatiquement les moyens de réglage de débit sur une durée momentanée prédéterminée d1 au moins cinq fois plus courte que la durée de décompte prédéterminée D1 . Ce ratio permet de ne pas trop solliciter les moyens de réglage du débit de fluide. For vaporization efficiency, the end of the fluid transport pipeline from the reservoir to the vaporization chamber enters the vaporization chamber. This heated pipe end is still kept filled with fluid through this microcontroller control, allowing continuous flow and reactive control to the steam making demand. Indeed, by heat and pressure, the water present in this end is "propelled" into the vaporization chamber and the pipe is then empty of fluid, which could defuse the fluid control means. The momentary control of the fluid flow control means makes it possible to fill the end of the fluid pipe. Momentary control means a command lasting a substantial number of seconds. According to the invention, the control unit, at the end of countdown D1 without receiving the actuating signal, has means for automatically controlling the flow control means for a predetermined momentary duration d1 at least five times shorter than the predetermined counting time D1. This ratio makes it possible to avoid overloading the means for adjusting the fluid flow rate.
Selon l'invention, à la fin du décompte « D1 » (qui est le premier décompte) sans réception du signal d'actionnement, l'unité de commande a des moyens pour commander automatiquement les moyens de réglage de débit sur une première durée momentanée « d1 » au moins cinq fois plus courte que la durée du premier décompte D1 , et a des moyens pour ensuite décompter une deuxième durée prédéterminée D2 à la fin de laquelle sans réception du signal d'actionnement, les moyens de réglage de débit sont commandés automatiquement sur une deuxième durée momentanée d2 identique à la première durée momentanée d1 . En effet si au bout du deuxième décompte -certes plus court que le premier décompte- la pompe ou équivalent n'a pas été sollicitée par le fonctionnement, les probabilités que l'utilisateur n'utilise pas l'appareil sont élevées, et la pompe est actionnée au bout d'une attente plus courte. According to the invention, at the end of the countdown "D1" (which is the first count) without receiving the actuation signal, the control unit has means for automatically controlling the flow control means on a first momentary duration "D1" at least five times shorter than the duration of the first count D1, and has means to then count down a second predetermined duration D2 at the end of which without receiving the actuating signal, the flow control means are controlled automatically on a second momentary duration d2 identical to the first momentary duration d1. Indeed if after the second count -certes shorter than the first count- the pump or equivalent was not solicited by the operation, the probabilities that the user does not use the device are high, and the pump is activated after a shorter wait.
Selon l'invention, les moyens de compensation commandent temporellement les moyens de réglage en fonction : d'au moins la consigne de température de chauffe de la chambre de vaporisation, et /ou d'au moins le volume intérieur de l'extrémité de la canalisation de transport du fluide agencée dans la chambre de vaporisation. En effet ces deux paramètres jouent un rôle dans l'expulsion hors de l'extrémité de la canalisation du volume d'eau présent. Plus la température de consigne de chauffe de la chambre de vaporisation sera élevée, plus vite le fluide sera expulsé. Le volume intérieur définit la quantité substantiellement « poussée » de fluide dans la chambre. De façon alternative, les moyens de compensation peuvent commander les moyens de réglage en fonction de la pression à l'intérieur de la chambre et/ou de la pression à l'intérieure de la canalisation d'amenée. According to the invention, the compensation means temporally control the adjustment means as a function of: at least the heating temperature setpoint of the vaporization chamber, and / or at least the interior volume of the end of the vaporization chamber; pipeline for transporting the fluid arranged in the vaporization chamber. Indeed, these two parameters play a role in the expulsion from the end of the pipe of the volume of water present. The higher the heating set point temperature of the vaporization chamber, the faster the fluid will be expelled. The interior volume defines the substantially "pushed" amount of fluid in the chamber. Alternatively, the compensation means can control the adjustment means as a function of the pressure inside the chamber and / or the pressure inside the supply line.
Selon l'invention, les moyens de compensation de l'unité de commande permettent de commander temporellement les moyens de réglage de débit de fluide selon un profil prédéterminé temporel en créneau. La commande est ainsi faite par impulsion temporelle sur les moyens de motorisation de la pompe, la vanne, ou moyen de réglage de débit de fluide similaire. Plus précisément dans une première alternative, les moyens de compensation de l'unité de commande permettent de commander les moyens de réglage de fluide selon un profil crénelé dont la durée prédéterminée de décompte est comprise entre 8 et 30 secondes et la durée momentanée de commande du créneau est comprise entre 1 et 5 secondes. Plus précisément, les moyens de compensation (13") de l'unité de commande permettent de commander selon un profil crénelé dont la première durée prédéterminée de décompte est comprise entre 25 et 30 secondes, dont la ou les durées suivantes de décompte sont comprises entre 8 et 12 secondes et dont la durée momentanée de commande du créneau est identique et égale à 2 secondes According to the invention, the compensation means of the control unit make it possible to temporally control the fluid flow control means according to a predetermined time slot profile. The control is thus made by time pulse on the drive means of the pump, the valve, or similar fluid flow control means. More precisely in a first alternative, the compensation means of the control unit used to control the fluid control means according to a crenellated profile whose predetermined duration of counting is between 8 and 30 seconds and the momentary duration of control of the slot is included between 1 and 5 seconds. More precisely, the compensation means (13 ") of the control unit make it possible to control according to a crenellated profile whose first predetermined duration of counting is between 25 and 30 seconds, whose following duration (s) of counting are between 8 and 12 seconds and whose momentary control time of the slot is identical and equal to 2 seconds
Dans une deuxième alternative, les moyens de compensation de l'unité de commande permettent de commander automatiquement les moyens de réglage de débit de fluide selon un profil temporel cyclique. Encore plus précisément, les moyens de compensation de l'unité de commande permettent de commander selon un profil crénelé cyclique dont la durée complète de cycle est comprise entre 25 et 35 secondes, préférentiellement 30 secondes et la durée momentanée de commande du créneau est comprise entre 2 et 5 secondes bornes incluses, préférentiellement égale à 2 ou 3 secondes. In a second alternative, the compensation means of the control unit make it possible to automatically control the fluid flow control means according to a cyclic time profile. Even more precisely, the compensation means of the control unit make it possible to control according to a cyclic crenellated profile whose complete cycle time is between 25 and 35 seconds, preferably 30 seconds and the momentary duration of control of the slot is between 2 and 5 seconds inclusive, preferably equal to 2 or 3 seconds.
Selon l'invention, les moyens de compensation de l'unité de commande permettent de commander les moyens de réglage de débit de fluide pendant une durée complète comprise entre 2 et 4 minutes, préférentiellement 3 minutes, aussi longtemps que l'unité de commande ne reçoit pas de signal d'actionnement des moyens de réglage de débit. Après cette durée écoulée sans réception de signal d'actionnement, l'appareil sort du cycle de compensation. According to the invention, the compensation means of the control unit make it possible to control the fluid flow control means for a complete duration of between 2 and 4 minutes, preferably 3 minutes, as long as the control unit receives no actuation signal from the flow control means. After this elapsed time without receiving an actuation signal, the device exits the compensation cycle.
Selon l'invention, si pendant le décompte, l'unité de commande reçoit depuis le moyen d'actionnement un signal d'actionnement des moyens de réglage de débit, alors elle commande la remise à zéro du compteur à la fin de l'actionnement. Et le cycle recommence alors du début. According to the invention, if during the counting, the control unit receives from the actuating means an actuating signal of the flow control means, then it controls the resetting of the counter at the end of the actuation . And the cycle starts again from the beginning.
Selon l'invention les moyens d'actionnement permettant de commander les moyens de réglage de débit comportent un bouton manuel d'actionnement. Ainsi l'utilisateur a la possibilité de commander la fabrication de vapeur s'il le souhaite, et cette commande remet à zéro le compteur dès que l'utilisateur relâche le bouton 24. According to the invention, the actuating means making it possible to control the Flow control means comprise a manual actuation button. Thus the user has the possibility of controlling the steam production if he wishes, and this command resets the counter as soon as the user releases the button 24.
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 additionnellennent au bouton d'actionnement manuel, les moyens d'actionnement permettant de commander les moyens de réglage de débit peuvent comprendre des moyens pour détecter sa position fermée. 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 actuating button, the actuating means for controlling the flow control means may comprise means for detecting its closed position. 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 commande. 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.

L'appareil de coiffure 1 à vapeur destiné à la mise en forme des cheveux compred une première surface de traitement 4 destinée à venir en contact avec les cheveux, des moyens de réglage de débit de fluide 6, des moyens de vaporisation du fluide 7, des moyens de distribution 16 de la vapeur à destination des cheveux, une unité de contrôle 13 pour commander au moins les moyens de réglage de débit de fluide 6, les moyens de réglage de débit de fluide comprenant une pompe électrique ou une vanne, préférentiellement péristaltique 6. The hair styling apparatus 1 for shaping hair comprises a first treatment surface 4 intended to come into contact with the hair, fluid flow control means 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.
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 7", et être plaquées contre l'élément de chauffage 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 have steam distribution holes 7 ", 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 (not shown) for example.
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'usureje 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 piece of wearje 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 (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. 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 include a resistor and / or a thermistor (PTC) in direct or indirect contact 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.
Comme illustré en figure 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 7, et la deuxième partie étant une base déportée 1 1 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 1 1 et l'appareil portable 10. Ceci 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 entraînant la pompe ne sera sensiblement pas soumis à une température élevée et le tube de la pompe ne perdra pas en élasticité. 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. As illustrated in FIGS. 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, vaporization means 7, and the second part being a remote base 1 1 of the portable apparatus 10 may comprise the peristaltic pump 6 and a fluid reservoir 19, at least one fluid communication bead 21 may be provided between the base 1 1 and the portable device 10. This increases the spray capacity and guarantees a relatively light and manageable treatment device. In addition, the pump will not be subjected to a high temperature because it is remote from the heat source, that is, say means of vaporization: the motor driving the pump will not be substantially subjected to a high temperature and the tube of the pump will not lose elasticity. Alternatively to the two-part apparatus, according to the invention and as illustrated in FIG. 3, the apparatus may be more compact and composed of a single piece: the first jaw 2 comprises the control unit 13, a reservoir of fluid 19, the peristaltic pump 6, means for vaporizing the fluid 7 and the steam distribution means 16. This ensures a relatively compact treatment apparatus.
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 magnétiques de détection 14, 18 peuvent comprendre un interrupteur magnétique, un capteur à effet Hall. Plus particulièrement, toujours selon l'invention, les moyens magnétiques de détection 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. 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 magnetic switch with flexible blade (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.
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 7 et préférentiellement s'étendent sur sensiblement toute la longueur des moyens de vaporisation 7. Les chambres sont réalisées en aluminium. 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 ®, silicone, POM, PA. Le diamètre interne du tuyau d'entrée mesure 3mm et sa longueur dans la chambre est 17mm. As illustrated in Figure 4, the vaporization chamber 7 is separated into a first vaporization chamber 7 'is arranged upstream of the second chamber 7 "in the direction of the passage of steam.The internal volume (V1) of the first chamber 7 'is greater than the internal volume (V2) of the second chamber 7 ". The baffles 7 "'are distributed parallel to each other in the second chamber The first chamber 7' has a substantially parallelepipedal volume having a section selected from one of the following sections: rectangular section, trapezoidal as illustrated in FIG. distribution 16 are arranged laterally to the vaporization means 7 and preferentially extend over substantially the entire length of the vaporization means 7. The chambers are made of aluminum.The complete vaporization chamber has an approximate dimension of 83 mm in length, a width of 18mm and a height of 5mm The first chamber 7 'has a water inlet in the form of a water supply pipe 15 whose orifice is arranged at the first quarter of the length of the first chamber or alternatively at the center of the first chamber (not shown) and substantially in the middle of its width. There is a water inlet in the form of a pipe made of material comprising PTFE, Teflon®, silicone, POM, PA. The inner diameter of the inlet pipe measures 3mm and its length in the chamber is 17mm.
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 allumé et que la pompe est activée manuellement ou encore par détection de fermeture du lisseur, alors le microcontrôleur 13 laisse le compteur à 0. Dès que la pompe n'est plus activée (manuellement ou par détection de fermeture du lisseur) alors le microcontrôleur 13 commande la première incrémentation du compteur. Dès que le compteur atteint la première durée prédéterminée du premier créneau zéro (28 ici) alors il envoie à la CPU un signal d'actionnement momentané à la pompe (sur 2 secondes ici). Et ce décompte recommence aussi longtemps que la pompe n'est pas actionnée manuellement ou par détection de fermeture du lisseur. La deuxième incrémentation commence alors sur une deuxième durée prédéterminée de 10 secondes. Après un ou plusieurs décomptes temporels prédéterminés (ici 28s-2s-10s-2s-10s-2s-10s-2s...) l'appareil sort du cycle de compensation. Si la pompe n'est pas réactivée, alors l'extinction du produit est commandée. Si la pompe est réactivée, alors l'organigramme redémarre au début. Ceci permet, en durée de non activation de la pompe (ni manuellement ni par détection de position fermée du lisseur) d'alimenter momentanément et régulièrement le tuyau d'entrée 15 de la chambre. Ainsi la chambre a une vaporisation efficace par son tuyau d'amenée entrant à l'intérieur tout en ayant une réactivité importante à l'actionnement. Aucun compromis entre la réactivité et l'efficacité n'est fait ici. 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. 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. In operation and as illustrated in FIG. 5, when the device is switched on and the pump is activated manually or by closing detection of the straightener, then the microcontroller 13 leaves the counter at 0. As soon as the pump is no longer activated (manually or by detecting closure of the straightener) then the microcontroller 13 controls the first incrementation of the counter. As soon as the counter reaches the first predetermined time of the first zero slot (28 here) then it sends the CPU a momentary actuation signal to the pump (over 2 seconds here). And this count starts again as long as the pump is not operated manually or by detecting closure of the straightener. The second incrementation then begins on a second predetermined duration of 10 seconds. After one or more predetermined time counts (here 28s-2s-10s-2s-10s-2s-10s-2s ...) the unit exits the compensation cycle. If the pump is not reactivated then the product shutdown is controlled. If the pump is reactivated, then the flow chart restarts at the beginning. This allows, in duration of non-activation of the pump (neither manually nor by detecting the closed position of the straightener) to supply momentarily and regularly the inlet pipe 15 of the chamber. Thus the chamber has an effective vaporization by its inlet pipe entering the interior while having a high reactivity to the actuation. No compromise between responsiveness and efficiency is done here. 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. 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 .
