Description

HAIRDRESSING APPARATUS HAVING A MOBILE HEAD AND WITH FUNCTION OPERATING IN THE POSITION OF THE SAME

The present invention relates to the general technical field of hairdressing devices, for example for domestic use, and more specifically to the field of electric hairdressing devices designed to blow an air flow in order to dry and / or to facilitate shaping. hair.

The present invention relates more particularly to a hairdressing appliance comprising a blower module for generating an air flow, a heating element for raising the temperature of the air flow generated by said blower module, a manual gripping handle and a head blowing connected to said sleeve.

Hairdressing devices are known, of the hand-held hair dryer type, comprising a handle and a blowing head, which comprises an air outlet for directing a flow of forced air, hot or cold, towards the hair of a user. If such hair dryers are mainly used to dry damp hair, by evaporation of the water under the effect of the air flow blown by the hair dryer (drying function), they can however also be used in combination with a number of removable accessories designed to facilitate hair shaping (styling aid function). Intended to be fixed on the head of the hair dryer and to be traversed by the air flow emitted by the blowing head, these accessories - which can, for example, be of the diffuser or concentrator type - form nozzles modifying the shape of the air flow blown by the blower head of the hair dryer.

These known hair dryers, if they are generally satisfactory, nevertheless have certain drawbacks. In particular, the passage of the hair dryer from a mode of use for drying to a mode of use for styling aid generally involves on the part of the user, an adjustment of the hair dryer in order to obtain the required optimum supply air temperature and speed. However, the user can forget to make such a setting or not know which optimal setting to adopt to obtain the desired hairstyle result. This results for the user not only a risk of not obtaining the result he is looking for, but also a risk of deterioration of his hair.

In addition, the passage of the hair dryer from a mode of use for drying to a mode of use for styling aid also requires, on the part of the user, an operation of assembling / disassembling the accessories. Such an operation can sometimes be tedious, and there is also a non-negligible risk of burns when handling the accessories, as well as loss of the accessories, when the latter are not simply stored out of reach and are inaccessible to the user when the latter wishes to use them.

The objects assigned to the invention therefore aim to provide a new versatile hairdressing device of particularly simple and intuitive use.

Another object of the invention is to propose a new hairstyling device of particularly ergonomic design.

Another object of the invention is to propose a new hairstyling device of particularly simple and compact construction.

Another object of the invention aims to propose a new particularly robust and reliable hairdressing device.

Another object of the invention is to propose a new hairstyling device which makes it possible to obtain particularly effective drying and shaping of the hair under safe and comfortable conditions of use.

The objects assigned to the invention are achieved using a hairdressing apparatus comprising a blower module for generating an air flow, a heating element for raising the temperature of the air flow generated by said blower module , a manual gripping handle and a blowing head connected to said handle, said apparatus being characterized in that said blowing head is provided with at least a first air outlet and a second air outlet, said blowing head being mounted movable relative to the handle, between at least a first position in which said air flow is blown by the blowing head via said first air outlet and a second position in which said air flow is blown by the blowing head via said second air outlet, and in that it comprises means automatic adjustment of the operation of said blower module and said heating element, which automatic adjustment means control the operation of said blower module and said heating element in the position occupied by the blowing head relative to the handle.

Other features and advantages of the invention will appear and become more apparent on reading the description given below, with reference to the appended drawings, given solely by way of illustrative and nonlimiting example, among which:

FIG. 10 illustrates, in a side view in longitudinal section, the hairstyling appliance of FIGS. 6 to 9.

The hairstyling device 1, 1 ′ according to the invention is designed to be grasped and manipulated by hand. It is therefore a manual hairstyling device, preferably portable and typically intended for use in a domestic setting by a user lacking particular professional skills in hairstyling, that is to say both in terms of drying than styling, shaping the hair. Preferably, and in accordance with a first embodiment illustrated in FIGS. 1 to 5, the hairdressing apparatus 1 forms a hair dryer (or hair dryer), which allows a user to blow dry his wet or damp hair by blowing towards the hair with a forced air flow, hot or cold, and to facilitate shaping of the hair. The invention is however not limited to this specific embodiment and it is for example entirely conceivable that the hairdressing appliance 1 'forms a blowing hair brush, in accordance with a second embodiment illustrated in FIGS. 6 to 10, or any other hairdressing appliance having a function involving the blowing of an air flow on the user's hair, and which could be more specifically used for styling purposes, for example in direct contact with the hair (brushing, smoothing, etc.).

For the sake of brevity, the description which follows will nevertheless be essentially centered on a hairdressing appliance 1 of the hair dryer type (FIGS. 1 to 5) and on a hairdressing appliance 1 'of the blowing hair brush type (FIGS. 6 to 10) . Unless expressly indicated otherwise, the technical characteristics described in connection with the hairstyling appliance according to the first embodiment advantageously remain transposable mutatis mutandis to a hairstyling appliance according to the second embodiment (and vice versa). Identical or analogous elements between the two embodiments illustrated in the figures will bear, in the description which follows, the same references.

The hairstyling device 1, 1 ’according to the invention comprises a handle 2 (or handle) for manual grasping, intended to be grasped by the user to manipulate the hairstyling device 1, 1’. The handle 2 extends between a first end 3 and an opposite second end 4, preferably longitudinally along a first axis A-A ’. In the embodiments illustrated in the figures, the handle 2 is formed of a part - or an assembly of parts - generally tubular (for example of circular or elliptical mean section, constant or not), shaped and dimensioned to ensure it good handling by the user.

The hairdressing appliance 1, 1 ′ also comprises a blower module 5 designed to generate an (forced) air flow, and a blowing head 6 which is connected to said sleeve 2 and by means of which the air flow generated by the blower module 5 is directed out of the hairdressing appliance 1, 1 ′, so that it can be projected towards the hair of the user. Preferably, said blowing head 6 extends said sleeve 2 from one of its first 3 and second 4 ends, for example from said second end 4. Preferably still, said blowing head 6 then forms a terminal part of the hairdressing appliance 1, 1 ', as in the embodiments illustrated in the figures.

More specifically, the blowing head 6 is provided with at least a first air outlet 7 and a second air outlet 8, which are advantageously separate (and therefore different, not confused) from each other. Advantageously forming a unitary sub-assembly, the blowing head 6 is mounted movable relative to the handle 2, between at least a first position in which the air flow generated by the blowing module 5 is blown by the blowing head 6 by through the first air outlet 7, and a second position (Figures 5 and 10) in which said air flow is blown through the blowing head 6 through the second air outlet 8 through the latter. In other words, the hairstyling device 1, 1 ′ according to the invention is designed and configured to allow, by a displacement (that is to say by a modification of the arrangement, of positioning) of the blowing head 6 relative to the handle 2, alternately select one or the other of the first 7 and second 8 air outlets of the blowing head 6 by which the air flow will be blown by the blowing head 6.

Whatever its arrangement relative to the handle 2 of the hairdressing appliance 1, 1 ′, the blowing head 6 is preferably designed to remain permanently attached to said sleeve 2, the blowing head 6 not thus being provided ( in normal use) to be dissociated from the handle 2 of the hairdressing appliance 1, 1 'by the user.

Preferably, the blowing head 6 is mounted movable in rotation relative to the handle 2, around a second axis B-B ', as in the embodiments illustrated in the figures. In other words, the blowing head 6 is preferably mounted relative to the handle 2 in a pivot connection, so that it can thus rotate relative to the handle 2. The hairdressing device 1, 1 ' is thus advantageously designed and configured to allow the user, by pivoting the blowing head 6 relative to the handle 2, to alternately select one or the other of the first 7 and second 8 air outlets of the head blowing 6 by which the air flow will be blown by the blowing head 6. Even more preferably, the blowing head 6 is rotatably mounted relative to the handle 2 around a second axis BB 'which is coincident with the first axis AA 'of extension of the handle 2, as in the embodiments illustrated in the figures. However, the second axis B-B 'of rotation could be parallel to said first axis A-A' (and more or less offset from the latter). The kinematics of the blowing head 6 is thus simple and reliable, and allows intuitive handling of the hairdressing apparatus 1 by the user. Alternatively again, it could be envisaged that the second axis B-B 'is intersecting with said first axis A-A' at an angle typically between 5 and 15 °.

That said, other kinematics of the blowing head 6 relative to the sleeve 2 are obviously possible. For example, the blowing head 6 could, according to an alternative variant not illustrated in the figures, be mounted movable in translation relative to the handle 2, for example along a translation axis which would be parallel or coincident with the first axis A-A 'd' extension of the handle 2, or even even along a translation axis which would on the contrary be orthogonal to said first axis A-A 'of extension of the handle 2. It could then be for example a movement in pure translation, of the type slide connection, or of a movement in helical translation, of the blowing head 6 relative to the handle 2.

Preferably, the first 7 and second 8 air outlets have openings of different geometries. In other words, the useful air passage section of the opening of the first air outlet 7 is defined by a contour (or a plurality of contours) of shape different from the shape of the contour (or the plurality of contours) which respectively defines the useful air passage section of the opening of the second air outlet 8. The flow of air blown by the blowing head 6 will therefore thus affect a different profile depending on the outlet d 'air 7, 8 selected, so that the user can make use of the hairdressing device 1, 1' according to at least two different blowing configurations. Thus, the first air outlet 7 and second air outlet 8 are advantageously designed to blow, project, two air streams of different profiles, respectively a first air stream and a second air stream, each of the latter allowing the user to perform a different operation on his hair. For example, the first air flow can correspond to a drying air flow, of broad and diffuse profile, and of high flow rate (for example, of the order of 70 m ³ / h), to allow the user to quickly dry their hair. The second air flow may correspond to a shaping air flow, of concentrated and narrow profile, and of lower flow rate (for example, of the order of 50 m ³ / h), to allow the user to choose precisely the place of his hair to which the second air flow will be blown In this way, the user can skillfully and easily achieve shaping of his hair, such as for example waves, or on the contrary smoothing.

For example, in the first embodiment illustrated in FIGS. 1 to 5, where the hairdressing appliance 1 forms a hair dryer, the first air outlet 7 has an opening of generally circular shape that is substantially circular (FIG. 2), while that the second air outlet 8 (Figures 1 and 3) has a generally oblong, elongated opening. Thus, when the blowing head 6 occupies said first position relative to the handle 2, the hairdressing apparatus 1 can be used in a conventional manner for drying wet hair, the first flow of air blown by the blowing head 6 having, in the vicinity of the first air outlet 7, a substantially cylindrical or conical profile. When the blowing head 6 occupies said second position relative to the handle 2, the hairdressing device 1 can then be used to dry the hair while facilitating the shaping of the hair (for example, to carry out “brushing”), the second flow of air blown by the blowing head 6 forming, in the vicinity of the second air outlet 8, an air space which allows the user to choose with precision the place of his hair where to apply the air flow to achieve shaping.

By way of illustration and without limitation, the opening of the first air outlet 7, which is preferably intended to produce a first flow of drying air, may have a first useful section of air passage whose area is advantageously between 707 mm ² and 1,963 mm ² , and for example equal to 962 mm ² (which corresponds, for an opening of the first air outlet 7 of circular shape, to a diameter preferably between 30 and 50 mm, and preferably equal to 35 mm). The opening of the second air outlet 8 may advantageously have a second useful air passage section, the area of which is less than that of said first useful air passage section of the opening of the first air outlet 7. For example, the area of said second useful air passage section can be between 240 mm ² and 640 mm ² , and for example be equal to 360 mm ² (which corresponds, for a second air outlet opening 8 of oblong shape, at a length of about 60 to 80 mm and a width of about 4 to 8 mm, and preferably at a length of about 60 mm for a width of about 6 mm).

In the second embodiment illustrated in FIGS. 6 to 10, where the hairdressing apparatus 1 ′ forms a blower brush, the first air outlet 7 has for example an opening of general shape substantially oblong, elongated (FIG. 7), while the second air outlet 8 (Figures 6 and 8) has for its part, for example, an opening consisting of a multitude of orifices distributed between rows of brush bristles (or pins), each of these orifices being generally circular in shape. Thus, when the blowing head 6 occupies said first position relative to the handle 2, the hairdressing appliance 1 ′ can be used, for example, to pre-dry the hair by blowing a first air flow of wide and diffuse profile, and high throughput. When the blowing head 6 occupies said second position relative to the handle 2, the hairdressing device 1 ′ can then be used, for example, to brush the hair while finalizing the drying of the latter, by blowing a second flow. more concentrated profile air but less flow, closer to the hair brushed by the bristles (or pins) of the brush.

Thus, the hairstyling device 1, 1 ′ according to the invention advantageously allows the user to choose between at least a first mode of use (for example for drying) and a second mode of use (for example for setting in the form of the hair) of the hairdressing appliance 1, 1, 'by a modification of the arrangement or of the position of the blowing head 6 relative to the handle 2 (and preferably by a simple rotation of the blowing head 6 relative to the handle 2), which makes it possible to select, in a particularly simple and rapid manner, an air flow profile adapted according to the operation to be performed on the hair.

It is conceivable, without departing from the scope of the invention, that the first and second air outlets are one and / or the other formed by accessory parts assembled in a removable manner (for example by snap-fastening, screwing , press fitting, etc.) to the rest of the blowing head (variant not shown). In fact, this would allow the user to equip the hairdressing appliance 1, 1 'with two air outlets (and not just one, as is the case with conventional drying appliances), distinct and sections of different geometries, and to be able to use successively one or the other of them, without intermediate operations of disassembly / reassembly of parts, while nevertheless retaining the option of exchanging one or the other of these accessory parts according to the particular use that the user wishes to make of the hairdressing appliance.

It is however advantageous that the blowing head 6 forms on the contrary a coherent assembly, not intended to be disassembled by the user, the first 7 and second 8 air outlets being formed by one or more irremovable components (in normal use) belonging to the blowing head 6. Thus, by means of a displacement, a modification of the position (preferably, by a rotation) of the blowing head 6 relative to the handle 2 of the apparatus 1, 1 ', the user can, quite remarkably, select one or the other of the first air outlet 7 or second air outlet 8, and therefore advantageously choose the air flow profile that 'he wishes, without having to install or dismantle any accessory element of the hairdressing apparatus 1, the. The user thus benefits from an easy and rapid use of the device 1, the and is certain not to lose any element of the latter.

To allow easy use of the hairdressing device 1, 1 ′ in all circumstances, in particular for treatment of the hair from the back of the user's head, the first 7 and second 8 air outlets are preferably arranged and configured so that the air flow generated by the blower module 5 is blown by the blowing head 6 in a mean secant direction, and preferably substantially orthogonal, to the first axis AA ' longitudinal extension of the handle 2. In a particularly advantageous manner, the hairdressing device 1 1 ′ may be designed and configured so that the blowing head 6 blows the air flow in a substantially identical mean direction and direction which that either the first position or the second position occupied by the blowing head 6 relative to the handle 2. Thus, the user can alternatively use the hair styling device 1, 1 'in one then in the other of said first and second positions of the blowing head 6, without having to modify its manual grip on the handle 2 or to modify the general spatial orientation of the hairdressing apparatus 1, 1 ′.

In the preferential case where the blowing head 6 is movable in rotation relative to the handle 2, as in the preferred embodiments illustrated in the figures, the passage of the blowing head 6 from said first position to said second position corresponds more preferably to a rotation of said blowing head 6 by an angle of 180 ° around said second axis B-B '. In other words, the blowing head 6 of the hairdressing appliance 1, 1 ′ is designed and configured in such a way that the first 7 and second 8 air outlets of the blowing head 6 are arranged on either side of the second axis B-B 'of rotation of the blowing head 6 relative to the handle 2. This arrangement contributes to a practical and particularly intuitive handling of the hairdressing device 1, 1' by the user.

Whatever the kinematics of the movement of the blowing head 6 relative to the handle 2, the first and second positions of the blowing head 6 are preferably stable positions, so that the blowing head 6 cannot leave the position that it occupies unexpectedly, without voluntary action on the part of the user. As such, the hairstyling device 1, 1 ′ advantageously comprises means of indexing (not illustrated) of the blowing head 6 in said first and second positions relative to the handle 2, such as for example pairs of magnets, "goose bumps" or any other known and suitable means.

This being stated, it is understood that the invention is not however limited to the use of a blowing head 6 comprising only two air outlets 7, 8, in particular oriented at 180 ° one of the other relative to the second axis BB 'of rotation of the blowing head 6 relative to the handle 2, although this assumption is retained in the preferred embodiments illustrated in figures. Indeed, the blowing head 6 could quite well include a greater number of distinct air outlets and sections of different geometries (for example, 3 or 4), which could be selected by the user by displacement, and preferably by rotation, of the blowing head relative to the handle and positioning of the blowing head in as many corresponding distinct positions.

These three or four (or more) air outlets could then, for example, be regularly distributed around the second axis B-B ’of rotation, according to equal angular sectors as a function of the number of said air outlets. For example, one could thus envisage the implementation of three air outlets, distinct and having openings of different geometries, arranged in relation to each other so that the passage of the blowing head from a first position to a second position, then from this second position to a third position, corresponds for example to a rotation of the blowing head by an angle of 120 ° around said second axis B-B '. One could also consider, for example, the implementation of four air outlets, distinct and having openings of different geometries, arranged relative to each other so that the passage of the blowing head from a position given to another corresponds, for example, to a rotation of said blowing head by an angle of 90 ° around said second axis B-B '. In addition, the rotation of the blowing head around the second axis B-B ', to move the blowing head from a given position to another, could obviously correspond to a different angle of rotation of the ratio of 360 ° on the total number of separate air positions / outlets.

The blower module 5 of the hairdressing appliance 1, 1 ′ preferably comprises a motor-fan unit 10, itself comprising an electric motor 11. The motor-fan unit 10 can comprise a conventional axial fan with a propeller or a helix. Alternatively, the motor-fan unit 10 can advantageously comprise a fan of the helico-centrifugal or centrifugal type. The implementation of such a centrifugal or centrifugal fan can make it possible to obtain, with equivalent dimensions, a high internal pressure with an air flow rate substantially similar to that of a propeller or helical fan, but with a lower rotation speed and therefore noise generated by the smaller motor-fan unit 10. Preferably, the electric motor 11 of the fan motor group 10 is a brushless electric motor (so-called "brushless" motor or self-controlled synchronous machine with permanent magnets). Such a brushless motor is generally more robust and lighter than a conventional brushed electric motor. Less noisy and more energy efficient, it also offers greater flexibility and better precision in adjusting its rotation speed.

Preferably on-board within the hairdressing appliance 1, 1 ′, the blower module 5 can be arranged within the handle 2 or within the blowing head 6. More preferably, however, the blower module 5 of the hairdressing appliance 1 is assembled to the handle 2 at the first end 3 of the latter, the blowing head 6 being in turn movably mounted (preferably in rotation) relative to the handle 2 at the second end 4 of the latter, as in the embodiments illustrated in the figures. The blowing head 6 thus preferably extends from the second end 4 of the handle 2, while the blower module 5 extends the handle 2 from the first end 3 of the latter. Preferably, the blower module 5 is secured to the handle 2, at the first end 3 of the latter, without the possibility of relative movement of the blower module 5 relative to the handle 2, either by translation or by rotation. In addition, said blower module 5 can itself be extended by a power supply cord 9, as is illustrated for example in FIGS. 6 to 10. The blower module 5 of the hairdressing appliance 1, 1 ' is therefore preferably offset from the blowing head 6 and the handle 2 for gripping the hairdressing appliance 1, 1 '. It is thus possible to size the blower module 5 so as to generate an air flow with a high flow rate, economically, and without impacting the overall size of the blowing head 6 and of the handle 2. In addition, such an arrangement of the blower module 5 advantageously makes it possible to better balance the weight of the hairdressing apparatus 1, by a distribution of the masses on either side of the handle 2, which contributes to the comfort of use of this last.

In the case where the blower module 5 is arranged within the handle 2 or is assembled to the handle 2 at the first end 3 of the latter, the sleeve 2 can advantageously include a guide channel 12 for the air flow generated by the blower module 5 in the direction of the blowing head 6. Said guide channel 12 advantageously channels said air flow through handle 2, typically in the direction of the first end 3 of the handle 2 towards the second end 4 of the latter. The hairstyling appliance 1, 1 ′ may also advantageously comprise a deflector 13, designed and configured to guide the air flow generated by the blower module 5 from the guide channel 12 of the handle 2 towards the first outlet from air 7 when the blowing head 6 occupies said first position, and vice versa towards the second air outlet 8 when the blowing head 6 occupies said second position.

In the first embodiment of FIGS. 1 to 5, the motor-fan unit 10 advantageously comprises a fan 14 of the centrifugal type, and the blower module 5 comprises an internal working chamber 15 in the form of a scroll, within which is housed the motor-fan unit 10. Said working chamber 15 can, as illustrated in FIG. 5, be defined by the internal walls of two half-shells 16, 17 assembled together (for example, by screwing ) and secured to the handle 2 at the first end 3 of the latter. The blower module 5 is provided with an air inlet 18, by which the ambient air is sucked axially by the fan 14 within the working chamber 15, and an air outlet which is advantageously connected to the channel 12 for guiding the air in the handle 2 and through which the sucked air is discharged radially out of the working chamber 15. The blower module 5 also preferably comprises a grid (possibly removable and repositionable) for protecting the inlet of air 18 from the working chamber 15. As illustrated in particular in FIG. 5, the blower module 5 is preferably designed and configured so that the axis of the centrifugal fan 14 of the motor-fan unit 10 is substantially orthogonal to the first axis AA 'of longitudinal extension of the handle 2. The air inlet 18 of the working chamber 5 is preferably arranged so that the ambient air is sucked into the working chamber 15 in a direction substantially para It lies in the mean direction of blowing of the air flow through the blowing head 6 and, even more preferably, in an identical direction. One could however envisage, without departing from the scope of the invention, that the ambient air be sucked into the working chamber 15 in a secant direction, and for example substantially orthogonal, to the mean direction of blowing of the air flow by the blowing head 6.

As regards the second embodiment illustrated in FIGS. 6 to 10, in which the hairdressing apparatus 1 forms a blower hair brush, the motor-fan group 10 preferably comprises a fan 14 of the helical type. Attached to the handle 2 at the first end 3 of the latter, the blower module 5 comprises an internal working chamber 15 which is substantially cylindrical, within which the motor-fan group 10 is housed. The motor-fan group 10 is mounted so that the axis of the helical fan 14 is parallel, and preferably coincident, with the first axis A-A 'of longitudinal extension of the handle 2. The blower module 5 is provided with an inlet air 18, for example screen, by which the ambient air is drawn radially by the fan 14 within the working chamber 15, and an air outlet which is advantageously connected to the air guide channel 12 of the handle 2 and by which the aspirated air is discharged axially out of the working chamber 15.

Preferably, the blowing head 6 comprises an external casing 20 which defines the external shape and contour of the blowing head 6 and, advantageously, the external shape and contour of an end part of the hairdressing appliance 1, 1 'which is connected to the handle 2 of said hairdressing device 1, 1'. Advantageously, the external envelope 20 is shaped to allow manual gripping by the user, so that the latter can print directly by hand to said external envelope 20 (and therefore to the blowing head 6), a movement of movement of the blowing head 6 relative to the handle 2 - and preferably, a pivoting movement around the second axis B-B 'of rotation of the blowing head 6 relative to the handle 2 - to select one or the another of said first 7 and second 8 air outlets from the blowing head, and therefore the corresponding operating mode of the hairdressing appliance 1, 1 '.

Advantageously, the blowing head 6 comprises a nozzle body 19 for guiding the air flow out of the hairdressing appliance 1, towards the hair of the user. In the first embodiment illustrated in Figures 1 to 5, the body of nozzle 19 is advantageously embedded in said outer casing 20 (or fairing), formed for example of half-shells assembled by snap-fastening or by screwing. The rotation, by the user, of the external casing 20 of the blowing head 6 around the second axis B-B 'causes the joint body of the nozzle 19 to rotate around said second axis B-B'. The outer casing 20 can be shaped to give the blowing head 6 a particular aesthetic appearance, for example a generally cylindrical appearance as illustrated in example in FIGS. 1 to 5.

Advantageously, the outer casing 20 of the blowing head 6 extends generally longitudinally along a third axis C-C 'orthogonal to a median plane of the blowing head 6, said blowing head 6 being arranged relative to the handle 2 of so that the second axis B-B 'of rotation of the blowing head 6 is coincident with the first axis A-A' of longitudinal extension of the handle 2, and that said first A-A 'and second B-B' axes are inscribed in the median plane of the blowing head 6. The outer casing 20 therefore advantageously extends along a third axis C-C 'which is orthogonal to both the first axis A-A' of longitudinal extension of the handle 2 and to the second axis B-B 'of rotation of the blowing head 6, and over a substantially equal average length on either side of said first A-A' and second B-B 'axes.

In addition to the aesthetic effect of symmetry or quasi-symmetry which can be thus obtained, this particular arrangement advantageously contributes to a good general balance and to good maneuverability of the hairdressing apparatus 1 by the user.

As illustrated in particular in the sectional view of FIG. 5, the nozzle body 19, advantageously monolithic, preferably extends itself along the third axis CC 'of longitudinal extension of the blowing head 6 between, of on the one hand, a first end of the nozzle forming the first air outlet 7 of the blowing head 6 (which advantageously has an opening of generally circular shape, as mentioned above) and, on the other hand, a second end opposite nozzle forming, for its part, the second air outlet 8 of the blowing head 6 (which advantageously has an opening of generally oblong shape, elongated, in a direction perpendicular to the second axis B-B 'of the blowing head 6).

In this first particular embodiment, the hairdressing apparatus 1 also comprises a deflector 13, as envisaged above, for guiding the air flow generated by the blower module 5 from the guide channel 12 of the handle 2 alternately towards one or the other of said first 7 and second 8 air outlets, according to the position occupied by the blowing head 6. As illustrated in FIG. 5, the deflector 13 preferably comprises an elbow tubular element 21, mounted relatively fixed to the handle 3 and extending the air guide channel 12 of said handle 2 along the first axis A-A 'of extension of the handle 2. Thus, the blowing head 6 advantageously rotates around the bent tubular element 21 of the deflector 13, when it passes from one to the other of said first and second positions.

In a particularly preferred manner, the bent tubular element 21 forms with the handle 2 a monolithic part (FIG. 5), which in particular makes it possible to limit the number of parts of the hairdressing apparatus 1, and therefore to facilitate its manufacture .

As illustrated in FIG. 5, the nozzle body 19 advantageously comprises an air inlet orifice 22, of dimensions combined with those of the bent tubular element 21 of the deflector, and through which said bent tubular element 21 penetrates into the nozzle body 19, along the second axis BB 'of rotation of the blowing head 6. The bent tubular element 21 and the nozzle body 19 are advantageously configured and arranged relative to each other of so that, when the blowing head 6 occupies said first position, the bent tubular element 21 directs the air flow in the nozzle body 19 towards the first nozzle end forming the first air outlet 7 of the blowing head 6, while preferably preventing any air leakage in the direction of the second opposite nozzle end. Conversely, the bent tubular element 21 and the nozzle body 19 are advantageously configured and arranged relative to each other so that, when the blowing head 6 occupies said second position (in this case, at the following a rotation of the blowing head 6 by an angle of 180 ° around the second axis B-B '), the element bent tubular 21 then directs the air flow in the nozzle body 19 towards the second nozzle end forming the second air outlet 8 of the blowing head 6, while preferentially preventing any air leakage in the direction from the first opposite nozzle end (Figure 5). As illustrated, the deflector 13 (and in particular the bent tubular element 21 of the latter) and the nozzle body 19 are advantageously shaped and arranged to subject the air flow coming from the air guide channel 12 of the handle 2 a 90 ° deflection towards one or the other of the first 7 and second 8 air outlets.

A different design of the blowing head 6 of the hairdressing apparatus 1 can obviously be envisaged, such as, for example, that illustrated in FIGS. 6 to 10 in connection with the second preferred embodiment of the hairdressing apparatus 1, 1 'according to the invention.

The hairdressing apparatus 1 ’illustrated in FIGS. 6 to 10 forming a blowing hair brush, the blowing head 6 advantageously here has an external shape substantially analogous to that of a conventional hair brush. As such, the blowing head 6 thus extends longitudinally along a fourth axis D-D 'parallel to, and preferably coincident with, the second axis B-B' of rotation of the head relative to the handle 2. As illustrated, the blowing head 6 is also arranged relative to the handle 2 so that the second axis B-B 'of rotation of the blowing head 6 is coincident with the first axis A-A' of longitudinal extension of the handle 2 .

As illustrated in particular in FIG. 10, the blowing head 6 can comprise a nozzle body 19, which this time is not in the form of a separate part mounted in the outer casing 20 of the blowing head 6 , but which is on the contrary directly defined by an inner wall of said outer casing 20. Said outer casing 20 may, similarly to the first embodiment, be formed of a plurality of shell elements assembled together (for example , by snap-fastening or screwing). Said nozzle body 19 then advantageously extends along a fifth axis EE 'orthogonal to the fourth axis DD' of longitudinal extension of the blowing head 6, between, on the one hand, a first nozzle end forming the first outlet d head air 7 blowing 6 and, on the other hand, a second opposite nozzle end forming, for its part, the second air outlet 8 of the blowing head 6.

According to an alternative embodiment, the external envelope 20 may comprise at least one bar (not shown) arranged on the edge of the external envelope 20 so as to come into contact with the hair during the styling operation. This bar is preferably heating, or at least it is capable of transmitting to the hair part of the heat from the flow of drying air circulating in the blowing head 6. For example, the bar can be made of heat conductive material , such as a metallic material for example (steel, aluminum, etc.) and be in direct contact with the flow of drying air circulating inside the nozzle 19. For example, the strip can pass through the entire thickness of the outer casing 20 and protrude on the one hand, inside the nozzle 19 to be in contact with the drying air flow and on the other hand, outside to be in contact with the hair. Such a bar then makes it possible to form a projecting edge, preferably heating, coming into contact with the hair during the styling operation, which gives the hair a bolduc effect. Bolduc effect is understood to mean the formation of harmonious waves in a lock of hair, like the waves we give to bolduc ribbon by rubbing it against a scissor blade, to make pretty gift packages. Preferably, the external envelope comprises two bars opposite one another, substantially parallel, and arranged on either side of the fourth axis D-D 'so as to be able to achieve the bolduc effect in any direction of use of the hair styling device.

The first air outlet 7 of the blowing head 6 advantageously has an opening of generally substantially oblong shape, elongated, in a general direction parallel to the fourth axis D-D 'of longitudinal extension of the blowing head 6 (Figure 7). The second air outlet 8 has, for example, an opening consisting of a multitude of orifices of generally circular shape, distributed between rows of bristles (or pins) of brush which is advantageously provided with the blowing head. 6, each of these orifices being of generally circular shape (Figures 6 and 8). In this second particular embodiment, the hairdressing device 1 ′ also comprises a deflector 13 for guiding the air flow generated by the blower module 5 from the guide channel 12 of the handle 2 alternately towards one or the other. other of said first 7 and second 8 air outlet, according to the position occupied by the blowing head 6. As illustrated in FIG. 15, the deflector 13 preferably comprises a bent tubular element 21, in this case formed of a frustoconical tube section closed at one end and the side wall of which is provided with an axial opening. Fixed relative to the handle 2, the bent tubular element 21, extends the air guide channel 12 of said handle 2 beyond the second end 3 and along the first axis A-A 'of extension of the latter.

As illustrated in FIG. 5, the nozzle body 19 advantageously comprises an air inlet orifice, of dimensions combined with those of the bent tubular element 21 of the deflector 13, and by means of which said bent tubular element 21 enters the nozzle body 19, along the second axis B-B 'of rotation of the blowing head 6. The respective configurations and arrangements of the elbow tubular elements 21 and nozzle body 19 of the hairdressing appliance 1' according to the second embodiment of FIGS. 6 to 10 are advantageously similar, if not identical, to those described above in connection with the bent tubular element 21 and corresponding nozzle body 19 of the hairdressing appliance 1 according to the first embodiment of the Figures 1 to 5, and produce substantially the same effects.

Advantageously, one and / or the other of the first 7 and second 8 air outlets of the blowing head may (have) also be provided with one or more deflector flaps, more or less inclined and preferably fixed, designed and configured to homogenize, if necessary, the spatial speed / flow profile of the air flow blown through the air outlet concerned. For example, in the embodiments illustrated in the figures, the first air outlet 7, the geometry of the opening of which is advantageously adapted to use of the hairdressing appliance 1, 1 'for drying / pre-drying purposes -drying of the hair, is provided with such deflector flaps 23. In the first embodiment of FIGS. 1 to 5, the deflector flaps 23 advantageously come in one piece with the nozzle body 19. Alternatively, the deflector flaps 23 can be formed by a separate insert, as in the second embodiment of the FIGS. 6 to 10. The second air outlet 8, the geometry of the opening of which is preferably adapted to use of the hairdressing appliance 1, 1 ′ for the purpose of styling aid or styling hair, it is devoid of deflector flaps.

The hairstyling appliance 1, 1 ′ according to the invention also comprises a heating element 24 designed to raise the temperature of the air flow generated by the blower module 5. Preferably on board the hairstyling appliance 1 , 1 ', the heating element 24 can be arranged within the blowing head 6 or within (that is to say inside) of the handle 2 of the latter. More advantageously, the heating element 24 is arranged (at least in part) within (that is to say inside) of the handle 2, and even more advantageously even inside the channel guide 12 of said handle 2, as in the embodiments illustrated in the figures, so as to be interposed in the air flow generated by the blower module 5. Such a configuration makes it possible in particular to reduce the size and the weight of the blowing head 6, and to simplify the design of the latter. It is typically an electric heating element, operating on the principle of the Joule effect, and whose power is preferably greater than 500 W. Preferably, the heating element 24 comprises at least one electric heating resistance formed winding of a metallic conducting wire (for example, in nichrome) around an insulating core. In the preferred embodiments illustrated in the figures, the heating element 24 is more precisely in the form of a winding of a metallic conductive wire (not illustrated) around an insulating core 25 (for example, made of mica) cross-shaped and provided at its ends with fixing fins. Advantageously, the hairdressing appliance 1, 1 ′ further comprises a thermal insulator 26, for example a tubular part 26 with a circular base, within which the heating element 24 is mounted, and which in particular makes it possible to protect the user from risk of burns by limiting heating of the handle 2. As illustrated in the figures, the inner wall of the thermal insulator 26 can advantageously define all or part of the guide channel 12 of the air flow mentioned above.

Preferably, the hairstyling device 1, 1 ′ also comprises an electronic module 27. Not necessarily intended to be handled directly by the user, nor even to be accessible by the latter, the electronic module 27 is advantageously designed to interact (directly or indirectly) with all or part of the various functional organs that the hairstyling apparatus can include 1. It is typically a card, an electronic circuit, a printed circuit ( "PCB") or of a set of electrical, electronic or electromechanical components, internal to the hairdressing appliance 1, 1 '. The electronic module 27 can be intended to ensure a particular mode of electrical supply (with, for example, a function of filtering, transformation or rectification of current), to ensure a control, a command or even a regulation of the operation of one and / or the other of the functional organs of the hairdressing apparatus 1, 1 '. Optionally, said electronic module 27 can comprise components such as an electric battery, a display, one or more microcontroller (s), etc. The electronic module 27 can possibly be connected to a certain number of sensors and sensors distributed in the hairdressing apparatus 1, 1 ′ and intended to measure, to monitor, physical quantities linked to the functioning of the latter (temperatures, voltages and intensities electrical, air flow speeds / flow rates, rotation speed of the fan 14 of the blower module 5, etc.), in order to optimally control the operation of the various functional organs of the hairdressing appliance 1 , 1 '.

More preferably, said electronic module 27 is an electronic module designed to control the operation of the blower module 5 and / or of the heating element 24 of the hairdressing appliance 1, 1 ’. Indeed, the blower module 5 and / or the heating element 24 of the hairdressing apparatus 1 may require, for their respective operation and according to the technologies employed, the implementation of one (or more) module (s). ) or specific electronic control card (s).

For example, when the electronic module 27 is designed to control the operation of the heating element 24, the electronic module 27 may include a circuit for controlling electrical power and / or specific regulation (power, temperature, etc.) of said heating element 24. In the preferred case where the blower module 2 comprises a brushless electric motor 1 1, as envisaged above, the control of said brushless electric motor 1 1 can be advantageously ensured by the electronic module 27. At this title, the electronic module 27 can then be designed to ensure in particular the switching of the electric current in the stator windings (phase control) of the motor 1 1 according to data from position sensors (for example, Hall effect), self-regulation of the speed of rotation, etc.

Preferably, as in the first preferred embodiment illustrated in Figures 1 to 5, such an electronic module 27 is advantageously arranged within the blowing head 6, preferably outside the air flow circulating within the latter. Advantageously, the blowing head 6 comprises a dedicated compartment 28, capable of receiving said electronic module 27.

Such an arrangement contributes to limiting the overall size of the hairdressing apparatus 1, 1 ′, in particular in the case where the electronic module 27 is designed to control the operation of the blower module 5 and / or of the heating element. 24 and that the latter are arranged outside the blowing head 6. Thus, when as mentioned above, the heating element 24 is arranged within the handle 2 and / or the blower module 5 is assembled within the handle 2 or at one end of the latter, the electronic module 27 is thus thus advantageously offset from the heating element 24 and / or from the blower module 5 which it controls, which makes it possible to limit the overall dimensions of the handle as much as possible. 2 and / or the blower module 5 connected to the latter.

However, given the mobile (and preferably rotary) nature of the blowing head 6, it may then prove difficult to ensure a simple and robust electrical connection between, on the one hand, the heating element 24 and / or the blower module 5 arranged outside the blowing head 6 (or any other functional member of the hairdressing apparatus 1, 1 ′ which would be connected to the electronic module 27 and which would be arranged outside the blowing head 6) and , on the other hand, the electronic control module 27 arranged in the blowing head 6. This is why, as in the first preferential embodiment illustrated in Figures 1 to 5, the electronic module 27 is preferably mounted, within of the blowing head 6, so as to remain stationary relative to the blowing module 5 and / or to the heating element 24 during the displacement, the modification of the position, of the blowing head 6 relative to the handle 2. As such, and as illustrated in example in fig ure 5, the nozzle body 19 may be provided with an additional orifice 29, which is opposite to the air inlet orifice by through which the bent tubular element 21 of the deflector 13 penetrates into the nozzle body 19. At the level of said additional orifice 29 is flush with or protrudes from the nozzle body 19 a portion of the bent tubular element 21 to which the electronic module 27 may be fixed, directly or through a specific support 30. Obviously, other suitable mounting configurations can be envisaged. For example, depending on its specific dimensions, the electronic module 27 could be mounted on the back of the bent tubular element 21 of the deflector 13.

In this way, the electrical connection between the heating element 24 and / or the blower module 5 and the electronic module 27 arranged in the blowing head 6 can advantageously be made very simply, using for example electrically conductive wires conventional (not shown), without risk of damaging the electrical wires by twisting or even without requiring the use of complex mobile electrical connection means (of the connection connector type, for example). The manufacturing cost of the hairdressing appliance 1 is thus limited and its reliability increased.

Being housed within the blowing head 6, and although preferably arranged outside of the air flow circulating through the latter, the electronic module 27 is likely to see its temperature increase significantly when the air flow generated by the module blower 5 is heated by the heating element 24 before being blown out of the apparatus 1 by the blowing head 6. In addition, and even if the heating element 24 is not activated or the apparatus hairdressing does not include such a heating element, the electronic module 27 is likely, during its normal operation, to heat up by itself under the effect in particular of the electric current which crosses it. In all cases, this results in a high risk of malfunction, or even total failure, of the electronic module 27, if the temperature of the latter is not controlled and comes to exceed a certain tolerance threshold.

In a particularly advantageous manner, the hairstyling device 1, 1 ′ may for this reason comprise a bypass channel 31 designed to capture a part of the air flow generated by the blower module 5 in order to ensure the cooling of the electronic module 27. The bypass channel 31 is thus designed and configured to collecting and diverting part of the forced air flow produced by the blower module 5 - before said air flow is, if necessary, heated by the heating element 24 - in order to guide and to blow the part of the air flow thus taken as close as possible to the electronic module 27 to ensure forced cooling of the latter.

In the case where the blower module 5 is arranged within the handle 2 or is assembled to the handle 2 at the first end 3 of the latter, said bypass channel 31 preferably extends at least partially in the handle 2. The bypass channel 31 is thus advantageously integrated into the handle 2. Even more preferably, the hair styling device 1, 1 ′ can be designed so that the guide channel 12 and the bypass channel 31 extend parallel to each other within the handle 2, advantageously along the first axis A-A 'of extension of the latter.

For example, in the first preferred embodiment illustrated in Figures 1 to 5, the bypass channel 31 opens, on the one hand, at the air outlet of the working chamber 15 of the blower module 5, to capture part of the air flow (fresh, that is to say not yet warmed by the heating element 24) generated by said blower module 5 and, on the other hand, in the immediate vicinity of the electronic module 27 which is arranged in the blowing head 6. As illustrated in example in FIG. 5, said bypass channel 31 can be formed, according to all or part of the length of the handle 2, by a free space formed between an interior wall of the handle 2 and an outer wall of the tubular thermal insulator 26. Such a design also advantageously makes it possible to cool the handle 2, which improves the comfort of use of the hairdressing device 1, 1 ’. Said bypass channel 31 can advantageously extend, at the level of the blowing head 6, inside a double-walled wall 32 forming a back of the bent tubular element 21, then through the support 30, mentioned above, by means of which the electronic module 27 is fixed to the bent tubular element 21.

Advantageously, the hairdressing appliance 1, 1 ′ can also comprise a circuit for reinjecting the air flow part captured in the air flow (main) blown by the blowing head 6, so that after contributing to cooling of the electronic module 27, the part of the air flow which has been captured by the bypass channel 31 can itself be blown towards the hair of the user via the air outlet (s) 7 , 8 of the blowing head 6. In this way, the cooling of the electronic module 27 does not substantially impact the flow rate of the air flow generated by the blowing module 5 and blown by the blowing head 6. For example, the nozzle body 19 of the blowing head 6 may be provided with an orifice (not shown) for reinjection of the air flow part captured directly inside the nozzle body 19, preferably downstream of the bent tubular element 21 of the deflector 13. Alternatively (or complementary), the outer casing 20 of the blowing head 6 can be provided with gills (or equivalent) by which all or part of the flow part of captured air can escape out of the blowing head 6, and therefore out of the appliance 1, 1 '. Thus, the part of the air flow used to cool the electronic module 27 can be discharged towards the outside of the hairdressing appliance 1, 1 ′ without impacting (or at least without significantly impacting) the temperature of the (main) air flow blown by the blowing head 6 towards the user's hair.

Typically, said bypass channel 31 can be dimensioned in order to allow the passage within it of an air flow of between 1 and 10 m ³ / h, to allow efficient cooling of the electronic module 27.

According to the invention, the hairdressing appliance 1, T comprises automatic means 33 for adjusting the operation of the blower module 5 and the heating element 24, which automatic adjustment means 33 (automatically) control the operation of the module. blower 5 and the heating element 24 in the position occupied by the blowing head 6 relative to the handle 2. In other words, these are adjustment means on which the user acts not directly, but indirectly by l intermediary of a displacement, a change of position, of the blowing head 6 relative to the handle 2. Said automatic adjustment means 33 thus cooperate with the blowing module 5 and the heating element 24 (the case if necessary, via the electronic module 27 mentioned above) in order to automatically modify the respective operation in response to a modification, operated by the user, of the position of the blowing head 6 by r input to handle 2. Such automatic adjustment means 33 can be formed by any means otherwise known as such and adapted to such an automatic control function. For example, said automatic adjustment means 33 may in particular comprise one or more switches or contactors (electrical, optical, mechanical or even magnetic), and / or one or more potentiometers, and / or one or more or sensors for position of the head blower 6 relative to the handle 2. Typically arranged at the interface between the blower head 6 and the handle 2 (Figures 5 and 10), and electrically connected to the blower module 5 and / or to the heating element 24 ( if necessary, by means of the electronic control module 27 mentioned above), such automatic adjustment means 33 can be activated or deactivated depending on the position occupied by the blowing head 6 relative to the handle. 2, to modify in return the operation of the blower module 5 and of the heating element 24. In this way, it is advantageously possible to provide that each of said first and second positions of the blowing head 6 c corresponds to a different, and preferably predefined, adjustment of the operation of the blower module 5 and of the heating element 24.

Preferably, said automatic adjustment means 33 of the operation of the blower module 5 and of the heating element 24 are designed and configured so that at said first position of the blowing head 6 correspond a first speed F1 and a first temperature T1 of the air flow blown by the blowing head 6 (therefore via the first air outlet 7 of the latter). Conversely, said automatic adjustment means 33 are preferably designed and configured so that at said second position of the blowing head 6 correspond a second speed F2 and a second temperature T2 of the air flow blown by the blowing head 6 (by the intermediary therefore, this time, the second air outlet 8 of the latter).

Even more preferably, said first F1 and second F2 speeds of the air flow blown by the blowing head 6 are different from each other, and said first T1 and second T2 temperatures of the air flow blown by the blowing head 6 are different from each other. However, it nevertheless remains conceivable that said automatic adjustment means 33 are designed and configured to cooperate with the blower module 5 and the element. heater 24 in order to automatically maintain an identical speed or temperature of the supply air flow regardless of the position of the supply head 6, and therefore whatever the air outlet 7, 8 selected and the geometry of the opening of the latter.

Thus, each of said first and second positions of the blowing head 6 can automatically be associated with a speed-temperature couple of the blown air flow which can be advantageously predefined and optimized for a particular use of the hairdressing appliance 1, 1 '. Said first speed F1 and first temperature T1 of the air flow blown by the blowing head 6 can be advantageously predefined and optimized for use of the hairdressing appliance 1 for hair drying purposes. Said first position of the blowing head 6 can thus advantageously correspond to a so-called hair drying position. Conversely, said second speed F2 and second temperature T2 of the air flow blown by the blowing head 6 can in turn be advantageously predefined and optimized for use of the hairdressing apparatus 1 for the purpose of assisting in setting in the shape of hair. Said second position of the blowing head 6 can thus advantageously correspond to a position known as shaping (styling) of the hair.

As such, and in an illustrative and nonlimiting manner, said first temperature T1 of the air flow blown by the blowing head 6 can advantageously be between 64 and 104 ° C, and more advantageously still equal to 84 ° C. Said first speed F1 of the air flow blown by the blowing head 6 may in turn be advantageously between 35.7 km / h and 99.0 km / h, and more advantageously still equal to 72.8 km / h . Said second temperature T2 of the second flow of air blown by the blowing head 6 can advantageously be between 60 and 100 ° C, and more advantageously still equal to 80 ° C. Said second speed F2 of the air flow blown by the blowing head 6 may in turn be advantageously between 78.1 km / h and 208.3 km / h, and more advantageously still equal to 138.9 km / h .

Advantageously, the automatic adjustment means 33 are designed and configured so that at said first position of the blowing head 6 correspond a first operating power P1 of the element heating 24 and a first speed V1 of rotation of the fan 14 of the motor-fan unit 10 of the blower module 5. Said first power P1 and first speed V1 of rotation can advantageously be predefined and optimized for use of the hairdressing apparatus 1 , 1 'for hair drying purposes. As such, and in an illustrative and nonlimiting manner, said first power P1 for operating the heating element 24 may advantageously be between 1000 W and 2000 W, and more advantageously still be equal to 1500 W. The first speed V1 of rotation of the fan 14 can advantageously be between 13,000 rpm (revolutions per minute) and 17,000 rpm, and more advantageously still be equal to 15,000 rpm. According to the dimensioning of the blower module 5, such a first speed V1 of rotation of the fan 14 may advantageously correspond to a flow rate Q1 of the first flow of air blown by the blowing head 6 which is between 50 m ³ / h and 90 m ³ / h, and more advantageously still equal to 70 m ³ / h.

Conversely, said automatic adjustment means 33 are advantageously designed and configured so that at said second position of the blowing head 6 correspond a second operating power P2 of the heating element 24 and a second speed V2 of rotation of the fan 14 of said motor-fan unit 10. Said second power P2 and second speed V2 can advantageously be predefined and optimized for use of the hairdressing apparatus 1 for the purpose of assisting in the shaping of the hair. As such, and in an illustrative and nonlimiting manner, said second power P2 for operating the heating element 24 may advantageously be between 500 W and 1500 W, and more advantageously still be equal to 1000 W. The second speed V2 of rotation of fan 14 can advantageously be between 14,000 rpm and 18,000 rpm, and more advantageously still equal to 16,000 rpm. According to the dimensioning of the blower module 5, such a second speed V2 of rotation of the fan 14 can advantageously correspond to a flow rate Q2 of the second flow of air blown by the blowing head 6 which is between 30 m ³ / h and 70 m ³ / h, and more advantageously still equal to 50 m ³ / h.

Optionally, in the case where the hairdressing appliance 1 'forms a blower brush, in accordance with the second embodiment of the invention, the values given above in terms of speed, power and flow rate may be reduced by 60%, while the values given above in terms of temperature may remain substantially identical.

The hairstyling device 1, 1 ′ according to the invention is thus of particularly simple and intuitive use for the user, since the operation of the blower module 5 and / or of the heating element 24 can thus be advantageously predefined , preset, according to the position of the blowing head 6 relative to the handle 2. It is thus possible, during the manufacture of the hairdressing appliance 1, 1 'to define in advance the best settings of the appliance 1, 1 ′ as a function of the position of the blowing head 6. The result will therefore be advantageously optimized for the user of the hairdressing device 1, 1 ′, whatever their level of experience in hairdressing.

Preferably, the hairdressing apparatus 1, 1 ′ is designed so that the blowing head 6 thereof is able to occupy at least a third position (or even also a fourth position) relative to the handle 2, distinct from said first and second positions, and in which the automatic adjustment means 33 of the operation of the blower module 5 and of the heating element 24 are designed to stop the operation of the hairdressing appliance 1, 1 '. In other words, said automatic adjustment means 33 are designed and configured to cooperate with the blower module 5 and the heating element 24 so that, when the blowing head 6 occupies said third position relative to the handle 2, the fan speed 14 of the fan unit 10 of the blower module 5 and the power of the heating element 24 are both zero. To do this, the automatic adjustment means 33 can, for example, be designed to interact directly on the respective supply circuits of the blowing module 5 and of the heating element 24, or even possibly, to interact with the electronic control module (s) 27 mentioned previously. Thus, stopping the operation of the hairdressing apparatus 1, 1 ′ can be advantageously obtained by a simple change of position (and preferably a simple rotation), operated by the user, of the blowing head. 6 relative to the handle 2, without the user therefore necessarily needing to act directly on any general on / off switch. Preferably, the hairdressing appliance 1, 1 ′ is designed and configured so that said third position (or stop position) corresponds to a position of the blowing head 6 relative to the handle 2 which is intermediate to said first and second positions. For example, in the case where the hairdressing appliance 1, 1 ′ is designed so that the passage of the blowing head 6 from said first position to said second position corresponds to a rotation of an angle of 180 ° of the head blowing 6 around the second axis B-B ', said third position may advantageously correspond, in a particularly intuitive manner to the user, to a rotation of the blowing head 6 by an angle of 90 ° around said second axis B- B ', from one and / or the other of said first and second positions. Alternatively, in the case where the blowing head 6 is movable, not in rotation but for example in translation relative to the handle 2 between said first position and said second position, it could be envisaged that said third stop position could correspond to a position located equidistant from said first and second positions in the direction of translation of the blowing head 6.

Optionally, and as illustrated in the figures, the hairstyling device 1, 1 ′ may also comprise manual means 34 for adjustment, by the user, of the operation of the blower module 5 and / or of the heating element 24. These are adjustment means, for example of the rocker switch, push button type and / or of the slide or wheel dimmer type, on which the user can possibly act directly to fine-tune the operation of the blower module 5 and / or the heating element 24. For example, said manual adjustment means 34 can be designed and configured to cooperate with the blower module 5 and / or the heating element 24 in order to more finely adjust the speed of rotation of the fan 14 of the blower module 5 and / or the power of the heating element 24. In addition, said manual adjustment means 34 could be designed and configured to electrically activate / deactivate the device 1, 1 'and therefore stop the operation, in particular in the case where the blowing head 6 of the latter is not designed to occupy a (third) stop position, as envisaged previously. Such manual adjustment means 34 can be positioned, for example, at the level of the handle 2 or at the level of the blower module 5, when the latter is assembled at the first end 3 of the latter as illustrated in the figures.

The hairstyling device 1, 1 ′ preferably comprises, in addition to said automatic means for adjusting 33 of the operation of the blower module 5 and of the heating element 24, means for manual activation / deactivation of the heating element 24. Thus, whatever the position of the blowing head 6 (and therefore the air outlet 7, 8 selected), and whatever the chosen setting of the operation of the blowing module 5 and / or the heating element 24 , it remains possible at any time for the user to stop at will the operation of the only heating element 24, so as to blow towards the hair only a flow of fresh air (that is to say unheated by the heating element 24).
