De manière remarquable, l'appareil de coiffure comprend des moyens de confinement de la vapeur diffusée, entre les deux surfaces plaquées l'une contre l'autre. Ces moyens de confinement permettent de préserver une quantité de vapeur au contact de la mèche de cheveux avec une répartition homogène, dans un espace de confinement disposé entre les deux surfaces qui pincent ladite mèche, en sorte de favoriser le traitement par vapeur. Cette vapeur demeure dans l'espace de confinement un laps de temps avant de s'échapper sous l'action du débit de vapeur. Le confinement de la vapeur permet avantageusement de réduire le débit de vapeur des moyens de vaporisation de l'unité de traitement portable. La vapeur est amenée et circule par des moyens de diffusion ou encore des moyens de projection, la circulation pouvant en effet se faire sans ou avec surpression.To this end, the invention relates to a hairstyling apparatus comprising a portable treatment unit provided with two arms configured to form a clamp provided with two surfaces disposed vis-à-vis which allow concomitantly the pinch of a lock of hair.

Toutefois un débit entre 0,5g/min et 5g/min par exemple sensiblement égal à 4 g/min reste possible pour un appareil de coiffure moins encombrant que celui décrit dans le document FR2967017A1 qui est capable de produire le même débit.The portable treatment unit 2 of the hairdressing appliance 1 also comprises means for projecting or diffusing steam 7 from the first surface 5 to the second surface 6. As illustrated in FIG. Figures 1 to 3 , the first arm 3 comprises a groove 10 provided with a bottom 11 in which there are arranged orifices 12 for the projection or diffusion of steam towards the second arm 4, when the clamp is closed. The first arm 3 also comprises at its distal portion 3b, a vaporization chamber (not shown) which allows the creation of steam and the projection or diffusion of this steam through the orifices 12. In one embodiment, the portable treatment unit 2 of the hairdressing appliance 1 according to the invention may have technical features comparable to those described in the patent application. FR 2 967 017 A1 filed by the applicant, as to the implementation of the vaporization chamber. Thus, this vaporization chamber comprises in particular a heating device (not shown) consisting of a positive temperature coefficient thermistor, called PTC, and a measuring device (not shown) of the temperature of the heating device consisting of a thermistor with a negative temperature coefficient, called CTN. These heating and measuring devices are arranged in a second housing zone 24 illustrated in FIG. figure 2 , under the first housing zone 22. Variants, known to those skilled in the art or innovative, also remain feasible for this vaporization chamber, without departing from the scope of the invention. Preferably, eight orifices 12 with a diameter of 1.2 mm are arranged in the bottom 11 of the groove 10. In addition, the steam projection or diffusion means are configured to project or diffuse the steam with a flow rate of between 0.degree. , 5 g / min and 2 g / min, preferably between 0.9 g / min and 1.2 g / min. Those skilled in the art are able to size said projection means or vapor diffusion, to obtain such a flow. However a flow rate between 0.5 g / min and 5 g / min for example substantially equal to 4 g / min is possible for a less bulky hairdressing device than that described in the document FR2967017A1 who is able to produce the same flow.

D'autres caractéristiques, également connues de l'homme du métier, sont également mises en oeuvre sur l'appareil de coiffure 1 selon l'invention. L'unité de traitement 2 portable comprend notamment une carte électronique (non illustrée) qui est configurée pour gérer l'activation des deux plaques chauffantes 17, 18 et de la chambre de vaporisation. Cette carte électronique est agencée à l'intérieur de l'un des deux bras 3, 4, par exemple dans la partie proximale 3a du premier bras 3. L'unité de traitement 2 portable comprend un capteur magnétique 25, illustré en figure 1, du type interrupteur à lame souple, dit ILS, qui permet de détecter la position fermée de la pince selon laquelle les deux surfaces 5, 6 sont rapprochées l'une contre l'autre et pincent une mèche de cheveux. Dans une variante, on pourrait remplacer l'interrupteur à lame souple par un capteur magnéto-résistif, dit MRS.Other features, also known to those skilled in the art, are also implemented on the hairdressing appliance 1 according to the invention. The portable processing unit 2 comprises in particular an electronic card (not shown) which is configured to manage the activation of the two heating plates 17, 18 and the vaporization chamber. This electronic card is arranged inside one of the two arms 3, 4, for example in the proximal portion 3a of the first arm 3. The portable treatment unit 2 comprises a magnetic sensor 25, illustrated in FIG. figure 1 , of the type with a flexible blade, called ILS, which makes it possible to detect the closed position of the clamp according to which the two surfaces 5, 6 are brought together against each other and pinch a lock of hair. In a variant, the flexible blade switch could be replaced by a magneto-resistive sensor, called MRS.

Tel qu'illustré sur les figures 1 à 3, la rainure 10 est mise en oeuvre dans la partie aval 17a de la première plaque chauffante 17 (ou première surface 5 pas nécessairement surface chauffante), relativement au sens de déplacement de l'unité de traitement 2 portable depuis la racine jusqu'à la pointe des cheveux, tel que représenté par la flèche 26 sur la figure 2. Cela permet de traiter par vapeur la mèche de cheveux avant le traitement par chauffe (respectivement, ou par pincement pas forcément chauffé). La rainure 10 débouche de préférence à ses deux extrémités sur les bords longitudinaux 5a, 5b de la première surface 5. On pourrait toutefois prévoir une variante selon laquelle la rainure 10 débouche uniquement sur l'un des bords longitudinaux 5a, 5b. Tel qu'illustré sur la figure 2, le médian 27 de la rainure 10 est positionné à une distance d1 du bord latéral aval 29 de la première plaque chauffante 17. Le rapport de cette distance d1 sur la largeur l1 de cette plaque chauffante 17 est de préférence compris entre 0,1 et 0,4. Par exemple, la largeur de la plaque est égale à 28,9 mm et la distance d1 est égale à 6,25 mm, correspondant à un rapport de 0,22.As illustrated on Figures 1 to 3 , the groove 10 is implemented in the downstream portion 17a of the first heating plate 17 (or first surface 5 not necessarily heating surface) relative to the direction of movement of the portable treatment unit 2 from the root to the tip of the hair, as represented by the arrow 26 on the figure 2 . This makes it possible to steam the strand of hair before the treatment by heating (respectively, or by pinching not necessarily heated). The groove 10 preferably opens at its two ends on the longitudinal edges 5a, 5b of the first surface 5. It could however provide a variant in which the groove 10 opens only on one of the longitudinal edges 5a, 5b. As illustrated on the figure 2 , the median 27 of the groove 10 is positioned at a distance d1 from the downstream side edge 29 of the first heating plate 17. The ratio of this distance d1 to the width 11 of this heating plate 17 is preferably between 0.1 and 0.4. For example, the width of the plate is equal to 28.9 mm and the distance d1 is equal to 6.25 mm, corresponding to a ratio of 0.22.

Tel qu'illustré sur les figures 1 à 3, une gorge 9 est agencée dans la partie aval 18a de la seconde plaque chauffante 18, en vis-à-vis de la rainure 10. Selon ce mode de réalisation, la gorge 9 et la rainure 10 présentent une forme et un volume sensiblement identiques. La gorge ou l'ensemble gorge et rainure permet de former les moyens de confinement de la vapeur diffusée. Comme pour la rainure 10, la gorge 9 débouche à ses deux extrémités sur les bords longitudinaux 6a, 6b de la seconde surface 6. La gorge 9 et la rainure 10 sont dimensionnées pour constituer concomitamment un espace de confinement 28 de la vapeur qui circule depuis les orifices 12. Cet espace de confinement 28 permet de contenir la vapeur autour de la mèche de cheveux pincée entre les deux surfaces 5, 6, avant de laisser cette vapeur s'échapper par les extrémités de la gorge 9 et de la rainure 10, grâce au renouvellement de la vapeur circulant par les orifices 12. Le confinement de la vapeur favorise le traitement par vapeur de la mèche de cheveux tout en utilisant un débit de vapeur réduit, de préférence compris entre 0,9 g/min et 1,2 g/min, en assurant un déplacement plus ou moins rapide de l'unité de traitement 2 portable le long de la mèche de cheveux. Par ailleurs, la mise en oeuvre de l'espace de confinement 28 entre les deux plaques chauffantes 17, 18 permet avantageusement de réchauffer la vapeur confinée dans ledit espace. Pour mettre en oeuvre cet espace de confinement 28, on choisit de préférence une largeur de rainure 10 comprise entre 2 mm et 6 mm, de préférence 2,5 mm et une profondeur de rainure 10 comprise entre 0,5 mm et 2 mm, de préférence 1 mm. En outre le volume de la rainure 10 est de préférence compris entre 200 mm3 et 275 mm3, de préférence 225 mm3. La longueur de la rainure 10 est de préférence comprise entre 20 mm et 220 mm, de préférence 90 mm. Les dimensions et le volume de la gorge 9 sont de préférence similaires, ce qui permet d'obtenir un volume de l'espace de confinement 28 compris entre 400 mm3 et 550 mm3, de préférence 450 mm3.As illustrated on Figures 1 to 3 a groove 9 is arranged in the downstream portion 18a of the second heating plate 18, opposite the groove 10. According to this embodiment, the groove 9 and the groove 10 have a substantially identical shape and volume. . The groove or the groove and groove assembly makes it possible to form the means for confining the diffused vapor. As for the groove 10, the groove 9 opens at its two ends on the longitudinal edges 6a, 6b of the second surface 6. The groove 9 and the groove 10 are dimensioned to concomitantly constitute a confinement space 28 of the vapor which circulates since the openings 12. This confinement space 28 makes it possible to contain the steam around the lock of hair pinched between the two surfaces 5, 6, before allowing this vapor to escape through the ends of the groove 9 and the groove 10, thanks to the renewal of the steam flowing through the orifices 12. The confinement of the steam promotes the steam treatment of the lock of hair while using a flow rate of reduced steam, preferably between 0.9 g / min and 1.2 g / min, ensuring more or less rapid movement of the portable treatment unit 2 along the lock of hair. Furthermore, the implementation of the confinement space 28 between the two heating plates 17, 18 advantageously allows to heat the vapor confined in said space. To implement this confinement space 28, a groove width of between 2 mm and 6 mm, preferably 2.5 mm and a groove depth of between 0.5 mm and 2 mm, is preferably chosen. preferably 1 mm. In addition, the volume of the groove 10 is preferably between 200 mm 3 and 275 mm 3 , preferably 225 mm 3 . The length of the groove 10 is preferably between 20 mm and 220 mm, preferably 90 mm. The dimensions and the volume of the groove 9 are preferably similar, which makes it possible to obtain a volume of the confinement space 28 between 400 mm 3 and 550 mm 3 , preferably 450 mm 3 .

Tel qu'illustré sur la figure 4, l'unité de traitement 2 portable comprend un pare-vapeur 20 qui est agencé sur le premier bras 3, au niveau du bord longitudinal proximal 5a de la première surface 5. Ce pare-vapeur 20 permet d'empêcher la vapeur qui s'échappe de l'espace de confinement 28, de venir dans la zone de préhension de l'unité de traitement 2 portable constituée par les parties proximales 3a, 4a des deux bras 3,4.As illustrated on the figure 4 , the portable treatment unit 2 comprises a vapor barrier 20 which is arranged on the first arm 3, at the proximal longitudinal edge 5a of the first surface 5. This vapor barrier 20 prevents the steam which is escapes from the confinement space 28, to come into the gripping zone of the portable treatment unit 2 constituted by the proximal portions 3a, 4a of the two arms 3,4.

La figure 5 illustre une variante de mise en oeuvre de moyens de projection ou diffusion de vapeur 7 sur la première surface 5. Ces moyens de projection ou diffusion de vapeur 7 comprennent deux rainures 10, 10' attenantes de conception similaire à celle illustrée en figure 1 à 3, agencées sur la partie aval 17a de la première plaque chauffante 17. Chaque rainure 10, 10' comprend des orifices 12, 12' agencés dans le fond 11, 11' de ladite rainure 10, 10', par lesquels est projetée, diffusée, transportée de la vapeur. Selon ce mode de mise en oeuvre, la gorge 9 agencée sur la seconde plaque chauffante 18 a une largeur correspondant à la largeur totale des deux rainures 10, 10'. Le débit de vapeur est également compris entre 0,5 g/min et 2 g/min, de préférence entre 0,9 g/min et 1,2 g/min. Le volume de l'espace de confinement est dans ce cas constitué par les volumes de la gorge 9 et des rainures 10, 10'. Ce volume est dans une plage de valeurs double à celle du volume de l'espace de confinement 28 du mode de réalisation des figures 1 à 3. Il s'agit en effet de doubler le canal ou la gorge de vapeur des modes de réalisation précédents de sorte que la vapeur suit un double canal et la mèche de cheveux est traitée à deux reprises par la vapeur. Les canaux peuvent être en circulation de fluide à une des extrémités de la ou des surfaces. Dans cette configuration de mise en circulation de la vapeur des canaux parallèles par un canal en forme complète de U, une alternative est que les orifices de sortie de vapeur ne sont présents que sur un des canaux (non illustrés).The figure 5 illustrates an alternative embodiment of the projection or vapor diffusion means 7 on the first surface 5. These means of projection or vapor diffusion 7 comprise two adjacent grooves 10, 10 'of similar design to that illustrated in FIG. figure 1 to 3 arranged on the downstream portion 17a of the first heating plate 17. Each groove 10, 10 'comprises orifices 12, 12' arranged in the bottom 11, 11 'of said groove 10, 10', through which is projected, diffused, transported steam. According to this mode of implementation, the groove 9 arranged on the second heating plate 18 has a width corresponding to the total width of the two grooves 10, 10 '. The steam flow rate is also between 0.5 g / min and 2 g / min, preferably between 0.9 g / min and 1.2 g / min. The volume of the confinement space is in this case constituted by the volumes of the groove 9 and grooves 10, 10 '. This volume is in a range of values twice that of the volume of the confinement space 28 of the embodiment of the Figures 1 to 3 . It is in effect to double the channel or the steam groove of the previous embodiments so that the steam follows a double channel and the lock of hair is treated twice by steam. The channels may be circulating fluid at one end of the one or more surfaces. In this configuration of circulating the steam of the parallel channels through a full U-shaped channel, an alternative is that the steam outlet ports are present only on one of the channels (not shown).

Sur la figure 6, les moyens de projection ou diffusion de vapeur 7 sont similaires à ceux des figures 1 à 3. En outre, une grille 13 est agencée au-dessus de la rainure 10, ce qui favorise une répartition homogène de la vapeur produite et déplacée, dans l'espace de confinement 28 comparable à celui illustré en figures 1 à 3. Une telle grille 13 peut être mise en oeuvre sur chaque rainure 10, 10' du mode de réalisation illustré en figure 5.On the figure 6 , the projection or vapor diffusion means 7 are similar to those of Figures 1 to 3 . In addition, a grid 13 is arranged above the groove 10, which promotes a homogeneous distribution of the produced and displaced vapor, in the confinement space 28 comparable to that illustrated in FIG. Figures 1 to 3 . Such a grid 13 may be implemented on each groove 10, 10 'of the embodiment illustrated in FIG. figure 5 .

Sur le mode de réalisation de la figure 7, la rainure 10 comprend une forme incurvée. La gorge 9 comprend une grille bombée 14 de forme complémentaire à celle de ladite rainure 10 incurvée. Cette grille bombée permet de répartir de manière homogène la vapeur dans l'espace de confinement 28 et, de tirer sur la mèche de cheveux lors du déplacement de l'unité de traitement 2 portable. Le volume de l'espace de confinement 28 sera dans une plage de valeurs similaire à celle du mode de réalisation des figures 1 à 3.On the embodiment of the figure 7 the groove 10 comprises a curved shape. The groove 9 comprises a curved grid 14 of shape complementary to that of said curved groove. This curved grid makes it possible to evenly distribute the vapor in the confinement space 28 and to pull on the lock of hair during the movement of the portable treatment unit 2. The volume of the confinement space 28 will be in a range of values similar to that of the embodiment of the Figures 1 to 3 .

Sur la figure 8, la rainure 10 et la gorge 9 sont de forme circulaire et définissent un cylindre 15 lorsque la pince est fermée, ledit cylindre 15 définissant l'espace de confinement 28. En outre, un rouleau perforé 16 est agencé en rotation selon un axe X à l'intérieur du cylindre 15. Ce rouleau perforé 16 pourra être motorisé. Le volume du cylindre 15 sera dans une plage de valeurs similaire à celle du volume de l'espace de confinement 28 du mode de réalisation des figures 1 à 3.On the figure 8 , the groove 10 and the groove 9 are of circular shape and define a cylinder 15 when the clamp is closed, said cylinder 15 defining the confinement space 28. In addition, a perforated roll 16 is arranged in rotation along an axis X to the interior of the cylinder 15. This perforated roll 16 may be motorized. The volume of the cylinder 15 will be in a range of values similar to that of the volume of the confinement space 28 of the embodiment of the Figures 1 to 3 .

Les figures 9, 10, 11 et 12 illustrent chacune des alternatives au mode de réalisation des moyens de confinement de la figure 2, mais peuvent être implémentées sur tous les modes décrits, seules ou en combinaison. Le point commun de ces modes est une ou deux pièce(s) référencées 30, 30a particulière(s) insérée(s) l'une ou chacune dans un ou deux espaces aménagés (appelés encore gouttières) dans la ou les plaques chauffantes. Une telle pièce introduite dans la plaque définit au moins partiellement le contour des moyens de confinement. Cette ou ces pièces permettent d'introduire des fonctionnalités supplémentaires au traitement par vapeur confinée.The Figures 9, 10 , 11 and 12 illustrate each of the alternatives to the embodiment of the containment means of the figure 2 , but can be implemented on all modes described, alone or in combination. The common point of these modes is one or two part (s) referenced 30, 30a particular (s) inserted (s) one or each in one or two spaces developed (called still gutters) in the or hotplates. Such a piece introduced into the plate at least partially defines the contour of the confinement means. This or these parts make it possible to introduce additional functionalities to the treatment with confined vapor.

Ainsi la figure 9 illustre un mode de réalisation de l'espacement avec une ou deux pièces en verre respectives insérées dans un espace aménagé plus grand que l'espace de la gorge finale des plaques chauffantes. La ou les gorges sont formées dans l'une ou les deux pièces en verre. La ou les pièces en verre peuvent être illuminées par une ou des diodes électroluminescentes (LED) pour former des barrettes lumineuses de chaque côté de la gorge de confinement.So the figure 9 illustrates an embodiment of the spacing with one or two respective glass pieces inserted in a developed space larger than the space of the final groove of the hotplates. The groove or grooves are formed in one or both glass pieces. The one or more glass pieces may be illuminated by one or more light-emitting diodes (LEDs) to form light strips on each side of the containment groove.

La figure 10 illustre une alternative dans laquelle la vapeur est amenée par deux canaux 31, 31a d'amenée de la vapeur issue de la chambre de vaporisation. Pour cela, la pièce particulière est insérée dans le plus grand espace aménagé sur la surface de traitement des plaques. Cette pièce permet de dériver la vapeur arrivant par le canal issu de la chambre de vaporisation.The figure 10 illustrates an alternative in which the steam is fed by two channels 31, 31a for supplying steam from the vaporization chamber. For this, the particular piece is inserted in the largest space arranged on the plate treatment surface. This part makes it possible to divert the steam arriving via the channel coming from the vaporization chamber.

La figure 11 illustre une alternative dans laquelle la ou les pièces particulières sont en aluminium et par exemple peintes, par exemple coulissées dans l'espace aménagé. La fixation peut se faire par queue d'aronde. On peut imaginer modifier la taille de la ou des gorges en remplaçant la ou les pièces particulières.The figure 11 illustrates an alternative in which the particular piece or pieces are made of aluminum and for example painted, for example slid into the landscaped space. Fixing can be done by dovetail. One can imagine changing the size of the groove or grooves by replacing the particular parts.

Enfin, la figure 12 illustre une alternative dans laquelle la ou les pièces particulières sont en silicone 30, 30a. Avantageusement et comme illustré, la pièce en silicone 30, 30a peut, lorsqu'elle est en place, dépasser en protubérance de la surface de la plaque chauffante 17, pour ainsi créer une zone de tension 32 ou zone de traction 32 des cheveux à côté de la gorge, permettant un lissage meilleur et plus respectueux de la mèche de cheveux.Finally, figure 12 illustrates an alternative in which the particular part or pieces are made of silicone 30, 30a. Advantageously and as illustrated, the silicone part 30, 30a can, when in place, protrude beyond the surface of the heating plate 17, thereby creating a tension zone 32 or traction zone 32 of the hair next to throat, allowing better and more respectful smoothness of the lock of hair.

Sur la figure 1, un peigne 19 est agencé en aval de la première surface 5 sur le premier bras 3. Ce peigne 19 permet de démêler et d'aérer la mèche de cheveux avant son passage entre les deux surfaces 5, 6.On the figure 1 a comb 19 is arranged downstream of the first surface 5 on the first arm 3. This comb 19 makes it possible to disentangle and aerate the lock of hair before it passes between the two surfaces 5, 6.

D'autres variantes de mise en oeuvre sont envisageables dans le cadre de l'invention. On peut notamment prévoir un espace de confinement qui est constitué uniquement par le volume d'une gorge 9 sur la seconde surface 6, ou uniquement par le volume d'une rainure 10 comprenant les orifices 12 de diffusion ou projection de vapeur, sur la première surface 5. Il convient dans ce cas de dimensionner ledit volume de la gorge 9 ou de la rainure 10, en sorte de constituer ledit confinement de vapeur.Other implementation variants are conceivable in the context of the invention. In particular, it is possible to provide a confinement space which is constituted solely by the volume of a groove 9 on the second surface 6, or solely by the volume of a groove 10 comprising the orifices 12 for diffusion or vapor projection, on the first 5. It is appropriate in this case to size said volume of the groove 9 or the groove 10, so as to constitute said vapor containment.

On peut également prévoir un agencement des moyens de confinement et des moyens de diffusion ou projection de vapeur 7 sur les surfaces 5, 6, séparément des plaques chauffantes 17, 18, lesdits moyens de confinement et lesdits moyens de diffusion ou projection de vapeur 7 étant disposés en aval desdites plaques chauffantes 17, 18.It is also possible to provide an arrangement of the confinement means and the vapor diffusion or projection means 7 on the surfaces 5, 6, separately from the heating plates 17, 18, the said confinement means and the said vapor diffusion or projection means 7 being arranged downstream of said heating plates 17, 18.

Selon les différentes variantes de réalisation précitées, on peut en outre remplacer les orifices 12 de diffusion ou projection de vapeur par une fente de diffusion ou projection de vapeur agencée dans le fond 11, 11' de la rainure 10, 10', en conservant un débit de vapeur compris entre 0,5 g/min et 2 g/min, de préférence entre 0,9 g/min et 1,2 g/min.According to the various embodiments mentioned above, it is also possible to replace the diffusion or vapor projection orifices 12 by a diffusion or vapor projection slit arranged in the bottom 11, 11 'of the groove 10, 10', while maintaining a steam flow rate between 0.5 g / min and 2 g / min, preferably between 0.9 g / min and 1.2 g / min.

Selon les différentes variantes de réalisation précitées, on peut ajouter un ioniseur embarqué qui sera destiné à amener des ions dans les moyens de confinement de vapeur pour éliminer l'électricité statique.According to the various embodiments mentioned above, it is possible to add an onboard ionizer which will be intended to bring ions into the vapor containment means to eliminate static electricity.
