Description

[0001] The present invention relates to the general technical field of hairdressing appliances, for example for domestic use, and more specifically to the field of portable electric hairdressing appliances designed to blow a flow of air in order to dry and / or facilitate the shaping of hair.

[0002] We are familiar with hair styling tools, such as handheld hair dryers, consisting of a handle and a nozzle with an air outlet to direct a forced stream of hot or cold air onto the user's hair. While such hair dryers are primarily used to dry damp hair by evaporating the water through the airflow (drying function), they can also be used with a number of detachable attachments designed to facilitate hair styling (styling aid function). These attachments—which can be diffusers or concentrators, for example—are designed to be placed on the hair dryer head and are directed by the airflow from the nozzle. They act as nozzles, modifying the shape of the airflow from the hair dryer's nozzle.US 2013 / 160316 is an example of a hair dryer from prior art.

[0003] While these well-known hair dryers are generally satisfactory, they do have some drawbacks. In particular, switching the hair dryer from drying mode to styling mode requires the user to assemble and disassemble the attachments. This can sometimes be tedious, and there is also a significant risk of burns when handling the attachments, as well as the risk of losing them, especially if they are simply stored out of reach and inaccessible to the user when needed. The objects of this invention therefore aim to provide a new, portable, multifunctional hair styling device that is particularly practical and easy to use.

[0004] Another object of the invention aims to provide a new portable hairdressing device with an ergonomic design and particularly intuitive use.

[0005] Another object of the invention is to propose a new portable hairdressing device of particularly simple and compact construction.

[0006] Another object of the invention is to propose a new portable hairdressing device that is particularly robust and reliable.

[0007] Another object of the invention aims to provide a new portable hair styling device that allows for particularly effective drying and shaping of hair under comfortable conditions of use.

[0008] The objects assigned to the invention are reached using a hair styling device according to claim 1.

[0009] Other features and advantages of the invention will become apparent and will be described in more detail upon reading the following description, with reference to the attached drawings, given solely by way of illustration and not limitation, among which: There figure 1 illustrates, in perspective view, a first embodiment of a hair styling appliance according to the invention, which forms a hair dryer. figure 2 illustrates, from a rear view, the hair styling device of the figure 1 .

There figure 8 illustrates, from a front view, the hair styling device of the figure 6 . There figure 9 illustrates, from a side view, the hair styling device of the figure 6 . There Figure 10 illustrates, according to a longitudinal sectional side view, the hairdressing apparatus of figures 6 to 9 .

[0010] The hair styling device 1, 1' according to the invention is designed to be grasped and manipulated by hand. It is therefore a portable, manual hair styling device, preferably intended for use in a domestic setting by a user without any particular professional skills in hairstyling, i.e. in terms of drying, styling, and shaping hair.

[0011] Preferably, and in accordance with a first embodiment illustrated in figures 1 to 5The hair styling appliance 1 forms a hair dryer (or hair dryer), which allows a user to dry their wet or damp hair by blowing a forced stream of hot or cold air towards the hair, and to facilitate hair styling. However, the invention is not limited to this specific embodiment, and it is entirely conceivable, for example, that the hair styling appliance 1' forms a blow-dry hairbrush, according to a second embodiment illustrated in the following: figures 6 to 10 , or any other portable hair styling device with a function involving blowing a stream of air onto the user's hair, and which could be more specifically used for styling purposes, for example in direct contact with the hair (brushing, straightening, etc.).

[0012] For the sake of brevity, the following description will nevertheless be primarily focused on a hair styling appliance 1 of the hair dryer type ( figures 1 to 5) and on a 1' hair styling device of the blow-drying hairbrush type ( figures 6 to 10 Unless expressly stated otherwise, the technical characteristics described in connection with the hair styling appliance according to the first embodiment remain advantageously transferable mutatis mutandis to a hair styling appliance according to the second embodiment (and vice versa ) . Identical or analogous elements between the two embodiments illustrated in the figures shall, in the description that follows, bear the same references.

[0013] The hair styling device 1, 1' according to the invention comprises a handle 2 (or grip) for manual handling, intended to be grasped by the user to manipulate the hair styling device 1, 1'. The handle 2 extends between a first end 3 and a second opposite end 4, preferably longitudinally along a first axis A-A'. In the embodiments illustrated in the figures, the handle 2 is formed from a piece—or an assembly of pieces—that is generally tubular (for example, with a circular or elliptical mean cross-section, constant or not), shaped and dimensioned to ensure a good grip by the user.

[0014] The hair styling device 1,1' also includes an onboard blower module 5, designed to generate a (forced) airflow, and a blower head 6 which extends the handle 2 and through which the airflow generated by the blower module 5 is directed out of the hair styling device 1,1', so that it can be projected towards the user's hair.

[0015] More precisely, the blower head 6 is provided with at least one first air outlet 7 and a second air outlet 8, which are distinct (and therefore different, not confused) from each other. Advantageously forming a unit subassembly, the blower head 6 is mounted to rotate relative to the handle 2, between at least a first position in which the airflow generated by the blower module 5 is blown by the blower head 6 via the first air outlet 7, and a second position ( Figures 5 And 10) in which said airflow is blown by the blower head 6 via the second air outlet 8 of the latter. In other words, the blower head 6 is mounted relative to the handle 2 by means of a pivot joint, so as to be able to rotate relative to the handle 2, and the hair styling device 1, 1' according to the invention is designed and configured to allow the user, by pivoting the blower 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 blower head 6 through which the airflow will be blown by the blower head 6. Preferably, the blower head 6 is designed to remain permanently attached to the handle 2 of the hair styling device 1, 1', the blower head 6 not being intended (in normal use) to be dissociated from the handle 2 of the hair styling device 1, 1' by the user.

[0016] According to the invention, the first 7 and second 8 air outlets have openings of different geometries. In other words, the effective air passage cross-section of the opening of the first air outlet 7 is defined by a contour (or a plurality of contours) with a different shape than the shape of the contour (or plurality of contours) that defines the effective air passage cross-section of the opening of the second air outlet 8. The airflow blown by the blower head 6 will therefore affect a different profile depending on the air outlet 7, 8 selected, so that the user can use the hair styling device 1, 1' in at least two different blowing configurations.Thus, the first air outlet 7 and second air outlet 8 are advantageously designed to blow, or project, two airflows with different profiles, respectively a first airflow and a second airflow, each allowing the user to perform a different operation on their hair. For example, the first airflow could be a drying airflow, with a wide, diffuse profile and a high flow rate (e.g., on the order of 70 m³ / h), to allow the user to dry their hair quickly. The second airflow could be a styling airflow, with a concentrated, narrow profile and a lower flow rate (e.g., on the order of 50 m³ / h), allowing the user to precisely choose the area of ​​their hair towards which the second airflow will be blown.In this way, the user can skillfully and easily style their hair, for example creating waves, or on the contrary, straightening it.

[0017] For example, in the first embodiment illustrated in figures 1 to 5 , where the hair styling appliance 1 forms a hair dryer, the first air outlet 7 has an opening of generally roughly circular shape ( figure 2 ), while the second air outlet 8 ( Figures 1 And 3) has a generally oblong, elongated opening. Thus, when the blower head 6 is in the first position relative to the handle 2, the hair styling appliance 1 can be used conventionally to dry wet hair, the first airflow blown by the blower head 6 having, in the vicinity of the first air outlet 7, a substantially cylindrical or conical profile. When the blower head 6 is in the second position relative to the handle 2, the hair styling appliance 1 can then be used to dry hair while also facilitating hair styling (for example, to create a " brushing "), the second airflow blown by the blower head 6 forming, in the vicinity of the second air outlet 8, an air blade which allows the user to precisely choose the area of ​​their hair where to apply the airflow to achieve the styling.

[0018] By way of illustration and without limitation, the opening of the first air outlet 7, which is preferably intended to produce a first drying airflow, may have a first effective air passage area advantageously between 707 mm² and 1963 mm², and for example equal to 962 mm² (which corresponds, for a circular first air outlet 7, 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 effective air passage area smaller than that of the first effective air passage area of ​​the first air outlet 7.For example, the area of ​​said second useful air passage section can be between 240 mm² and 640 mm², and for example be equal to 360 mm² (which corresponds, for a second air outlet opening 8 of oblong shape, to a length of about 60 to 80 mm and a width of about 4 to 8 mm, and preferably to a length of about 60 mm for a width of about 6 mm).

[0019] In the second embodiment illustrated in figures 6 to 10 , where the hair styling device 1' forms a blow-dry brush, the first air outlet 7, for example, has an opening that is generally oblong, elongated ( figure 7 ), while the second air outlet 8 ( figures 6 And 8The blower head 6, for example, features an opening made up of numerous orifices distributed between rows of brush bristles (or pins), each of these orifices being generally circular in shape. Thus, when the blower head 6 is in the first position relative to the handle 2, the hair styling tool 1' can be used, for example, to pre-dry the hair by blowing a first stream of air with a wide, diffuse profile and a high flow rate. When the blower head 6 is in the second position relative to the handle 2, the hair styling tool 1' can then be used, for example, to brush the hair while completing the drying process by blowing a second stream of air with a more concentrated profile but a lower flow rate, closer to the hair being brushed by the bristles (or pins).

[0020] Thus, the hair styling device 1, 1' according to the invention advantageously allows the user to choose between at least a first mode of use (for example drying) and a second mode of use (for example styling hair) of the hair styling device 1, 1,' by a simple rotation of the blower head 6 relative to the handle 2, which rotation makes it possible to select, in a particularly simple and quick way, an airflow profile adapted according to the operation to be carried out on the hair.

[0021] It is conceivable, without departing from the scope of the invention, that the first and second air outlets could be formed by accessory parts removably assembled (for example, by snap-fitting, screwing, press-fitting, etc.) to the rest of the blower head mounted for rotation relative to the handle (variant not illustrated). Indeed, this would allow the user to equip the hair styling device 1, 1' with two separate air outlets (and not just one, as is the case with conventional drying devices), each with different cross-sectional geometries, and thus be able to use either one successively, without intermediate disassembly / reassembly of parts, while still retaining the ability to exchange either of these accessory parts depending on the specific use the user wishes to make of the hair styling device.

[0022] However, it is advantageous that the blower head 6 forms a coherent unit, not intended to be disassembled by the user, the first 7 and second 8 air outlets being formed by one or more fixed components (under normal use) belonging to the blower head 6. Thus, by rotating the blower head 6 relative to the handle 2 of the device 1, 1', the user can remarkably select either the first air outlet 7 or the second air outlet 8, and therefore advantageously choose the desired airflow profile, without having to install or remove any accessory element of the hair styling device 1, 1'. The user thus benefits from quick and easy use of the device 1, 1' and is certain not to lose any part of it.

[0023] More precisely, the blow-dry head 6 is mounted to rotate relative to the handle 2 around a second axis BB', which preferably coincides with the first extension axis AA' of the handle 2, as in the embodiments illustrated in the figures. However, the second rotation axis BB' could be parallel to the first axis AA' (and more or less offset from it). The kinematics of the blow-dry head 6 are thus simple and reliable, and allow for intuitive handling of the hair styling appliance 1 by the user. Alternatively, the second axis BB' could be intersected by the first axis AA' at an angle typically between 5 and 15°.

[0024] To allow easy use of the hair styling device 1, 1' in all circumstances, particularly for treating the hair at the back of the user's head, the first 7 and second 8 air outlets are preferably arranged and configured so that the airflow generated by the blower module 5 is blown by the blower head 6 in an average direction that is secant, and preferably substantially orthogonal, to the first axis AA' of longitudinal extension of the handle 2. Particularly advantageously, the hair styling device 1, 1' can be designed and configured so that the blower head 6 blows the airflow in an average direction and a substantially identical sense regardless of whether the blower head 6 is in the first or second position relative to the handle 2.Thus, the user will be able to alternately use the hair styling device 1, 1' in one and then the other of the said first and second positions of the blow-dry head 6, without having to change his manual grip on the handle 2 or to change the general spatial orientation of the hair styling device 1, 1'.

[0025] As illustrated in the figures, the movement of the blower head 6 from said first position to said second position corresponds preferably to a rotation of said blower head 6 through an angle of 180° around said second axis B-B'. In other words, the blower head 6 of the hair styling appliance 1, 1' is designed and configured such that the first 7 and second 8 air outlets of the blower head 6 are arranged on either side of the second axis BB' of rotation of the blower head 6 relative to the handle 2. This arrangement contributes to practical and particularly intuitive handling of the hair styling appliance 1, 1' by the user.

[0026] Preferably, the first and second positions of the blower head 6 are stable positions, so that the blower head 6 cannot unexpectedly leave its position without deliberate action by the user. For this reason, the hair styling appliance 1, 1' advantageously includes indexing means (not shown) for the blower head 6 in said first and second positions relative to the handle 2, such as, for example, pairs of magnets, " chicken bottoms or any other known and suitable means.

[0027] Having stated this, it is understood that the invention is not limited to the implementation of a blower head 6 comprising only two air outlets 7, 8, in particular oriented at 180° to each other relative to the second axis BB' of rotation of the blower head with respect to the handle 2, although this assumption is retained in the preferred embodiments illustrated in the figures. Indeed, the blower head 6 could very well comprise 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 rotating the blower head relative to the handle and positioning the blower head in as many corresponding distinct positions.

[0028] These three or four (or more) air outlets would then preferably be evenly distributed around the second axis BB' of rotation, according to equal angular sectors depending on the number of said air outlets. For example, one could thus consider implementing three distinct air outlets with openings of different geometries, arranged relative to each other in such a way that the passage of the blower head from a first position to a second position, and then from this second position to a third position, corresponds, for example, to a rotation of the blower head by an angle of 120° around said second axis B-B'.One could also consider, for example, the implementation of four separate air outlets with different geometric openings, arranged relative to each other in such a way that moving the blower head from one position to another corresponds, for example, to a 90° rotation of said blower head around the second axis B-B'. Furthermore, the rotation of the blower head around the second axis B-B', to move the blower head from one position to another, could obviously correspond to a rotation angle different from the ratio of 360° to the total number of positions / separate air outlets.

[0029] 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 may comprise a conventional axial propeller or helical fan. Alternatively, the motor-fan unit 10 may advantageously comprise a helico-centrifugal or centrifugal fan. The use of such a helico-centrifugal or centrifugal fan can make it possible to obtain, for equivalent dimensions, a high internal pressure with an airflow substantially similar to that of a propeller or helical fan, but with a lower rotational speed and therefore less noise generated by the motor-fan unit 10. Preferably, the electric motor 11 of the motor-fan unit 10 is a brushless electric motor (so-called " brushless »or a self-piloted permanent magnet synchronous machine). Such a brushless motor is generally more robust and lighter than a conventional brushed electric motor. Quieter and more energy-efficient, it also offers greater flexibility and more precise speed control.

[0030] The blower module 5 can be arranged within the handle 2 or within the blower head 6. More preferably, however, the blower module 5 of the hair styling appliance 1 is assembled to the handle 2 at its first end 3, while the blower head 6 is mounted to rotate relative to the handle 2 at its second end 4, as illustrated in the embodiments shown in the figures. The blower head 6 thus extends from the second end 4 of the handle 2, while the blower module 5 extends from the handle 2 at its first end 3. Preferably, the blower module 5 is fixed to the handle 2 at its first end 3, without any possibility of rotation of the blower module 5 relative to the handle 2.In addition, the said blower module 5 can itself be extended by means of a power supply cord 9, as illustrated for example in the . figures 6 to 10 The blower module 5 of the hair styling appliance 1, 1' is therefore preferably located away from the blower head 6 and the handle 2 of the hair styling appliance 1, 1'. This allows the blower module 5 to be sized to generate a high airflow rate economically, without impacting the overall dimensions of the blower head 6 and the handle 2. Furthermore, this arrangement of the blower module 5 advantageously allows for better weight distribution of the hair styling appliance 1, by distributing the mass on either side of the handle 2, thus contributing to the user's comfort.

[0031] In the case where the blower module 5 is arranged within the handle 2 or is assembled to the handle 2 at its first end 3, the handle 2 may advantageously include a guide channel 12 for the airflow generated by the blower module 5 towards the blower head 6. This guide channel 12 advantageously channels the airflow through the handle 2, typically from the first end 3 of the handle 2 to its second end 4. The hair styling device 1,1' may further advantageously include a deflector 13, designed and configured to guide the airflow generated by the blower module 5 from the guide channel 12 of the handle 2 to the first air outlet 7 when the blower head 6 is in its first position, and conversely to the second air outlet 8 when the blower head 6 is in its second position.

[0032] In the first embodiment of figures 1 to 5 The motor-fan unit 10 advantageously comprises a centrifugal fan 14, and the blower module 5 comprises an internal volute-shaped working chamber 15, within which the motor-fan unit 10 is housed. This working chamber 15 may, as illustrated in the figure 5The blower module 5 is defined by the internal walls of two half-shells 16, 17 assembled together (for example, by screwing) and secured to the handle 2 at its first end 3. The blower module 5 is provided with an air inlet 18, through which ambient air is drawn axially by the fan 14 into the working chamber 15, and an air outlet which is advantageously connected to the air guide channel 12 of the handle 2 and through which the drawn-in air is expelled radially from the working chamber 15. The blower module 5 also preferably includes a grille (optionally removable and repositionable) to protect the air inlet 18 of the working chamber 15. As illustrated in particular in the figure 5The 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 ambient air is drawn into the working chamber 15 in a direction substantially parallel to the average direction of the airflow from the blower head 6 and, even more preferably, in the same direction. However, without departing from the scope of the invention, it could be envisaged that the ambient air be drawn into the working chamber 15 in a direction intersecting, and for example substantially orthogonal to, the average direction of the airflow from the blower head 6.

[0033] Regarding the second embodiment illustrated in figures 6 to 10in which the hair styling device 1 forms a blowing hairbrush, the motor-fan group 10 preferably includes a helical type fan 14. Attached to the handle 2 at its first end 3, the blower module 5 comprises a substantially cylindrical internal working chamber 15, within which the motor-fan assembly 10 is housed. The motor-fan assembly 10 is mounted so that the axis of the helical fan 14 is parallel, and preferably coincident, with the first longitudinal extension axis AA' of the handle 2. The blower module 5 is provided with an air inlet 18, for example screened, through which ambient air is drawn radially by the fan 14 into the working chamber 15, and an air outlet which is advantageously connected to the air guide channel 12 of the handle 2 and through which the drawn-in air is discharged axially out of the working chamber 15.Such an arrangement advantageously limits the radial bulk of the part of the hair styling device 1' formed by the handle 2 and the blower module 5.

[0034] Preferably, the blower head 6 comprises an outer casing 20 which defines the external shape and contour of the blower head 6 and, advantageously, the external shape and contour of a terminal part of the hair styling device 1, 1' which extends the handle 2 of said hair styling device 1, 1'. Advantageously, the outer casing 20 is shaped to allow manual gripping by the user, so that the latter can directly impart by hand to said outer casing 20 (and therefore to the blower head 6), a pivoting movement around the second axis BB' of rotation of the blower head 6 relative to the handle 2, to select one or the other of said first 7 and second 8 air outlets of the blower head, and thus the corresponding operating mode of the hair styling device 1, 1'.

[0035] Advantageously, the blower head 6 includes a nozzle body 19 to guide the airflow out of the styling appliance 1, towards the user's hair. In the first embodiment illustrated in figures 1 to 5 The nozzle body 19 is advantageously embedded in the outer casing 20 (or fairing), formed, for example, of half-shells assembled by snap-fit ​​or screw-fitting. Rotating the outer casing 20 of the blower head 6 around the second axis BB' by the user causes the nozzle body 19 to rotate concurrently around said second axis B-B'. The outer casing 20 can be shaped to give the blower head 6 a particular aesthetic appearance, for example, an overall cylindrical shape as illustrated in the example below. figures 1 to 5 .

[0036] Advantageously, the outer envelope 20 of the blower head 6 extends globally longitudinally along a third axis CC' orthogonal to a median plane of the blower head 6, said blower head 6 being arranged relative to the handle 2 so that the second axis BB' of rotation of the blower head 6 coincides with the first axis AA' of longitudinal extension of the handle 2, and that said first AA' and second BB' axes are inscribed in the median plane of the blower head 6. The outer envelope 20 therefore advantageously extends along a third axis CC' which is orthogonal to both the first axis AA' of longitudinal extension of the handle 2 and the second axis BB' of rotation of the blower head 6, and over a substantially equal average length on both sides of said first AA' and second BB' axes.

[0037] Besides the aesthetic effect of symmetry or near-symmetry that can be obtained in this way, this particular arrangement contributes advantageously to a good overall balance and good handling of the hair styling device 1 by the user.

[0038] As illustrated in particular in the cross-sectional view of the figure 5, the nozzle body 19, advantageously monolithic, itself extends preferentially along the third axis CC' of longitudinal extension of the blowing head 6 between, on the one hand, a first nozzle end forming the first air outlet 7 of the blowing head 6 (which advantageously has an opening of generally substantially circular shape, as mentioned above) and, on the other hand, a second opposite nozzle end forming, for its part, the second air outlet 8 of the blowing head 6 (which advantageously has an opening of generally substantially oblong shape, elongated, following a direction perpendicular to the second axis BB' of the blowing head 6).

[0039] In this first particular embodiment, the hair styling device 1 also includes a deflector 13, as described above, to guide the airflow generated by the blower module 5 from the guide channel 12 of the handle 2 alternately to one or the other of the first 7 and second 8 air outlets, depending on the position of the blower head 6. As illustrated in the figure 5 , the deflector 13 preferably comprises a bent tubular element 21, fixedly mounted relative to the handle 3 and extending the air guide channel 12 of said handle 2 along the first axis AA' of extension of the handle 2. Thus, the blower 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.

[0040] In a particularly preferential manner, the bent tubular element 21 forms a monolithic piece with the handle 2 ( figure 5), which notably allows limiting the number of parts of the hair styling device 1, and therefore making it easier to manufacture.

[0041] As illustrated in the figure 5The nozzle body 19 advantageously includes an air inlet orifice 22, with dimensions conjugate to those of the bent tubular element 21 of the deflector, and through which said bent tubular element 21 enters the nozzle body 19, along the second axis BB' of rotation of the blower head 6. The bent tubular element 21 and the nozzle body 19 are advantageously configured and arranged relative to each other so that, when the blower head 6 occupies said first position, the bent tubular element 21 directs the airflow in the nozzle body 19 towards the first nozzle end forming the first air outlet 7 of the blower head 6, while preferentially preventing any air leakage towards the opposite second 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 blower head 6 occupies said second position (in this case, following a rotation of the blower head 6 by an angle of 180° around the second axis B-B'), the bent tubular element 21 then directs the airflow in the nozzle body 19 towards the second nozzle end forming the second air outlet 8 of the blower head 6, while preferentially preventing any air leakage towards the opposite first 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 cause the airflow from the air guide channel 12 of the stick 2 to undergo a 90° deflection in the direction of one or the other of the first 7 and second 8 air outlets.

[0042] A different design for the blow-drying head 6 of the hair styling appliance 1 can obviously be envisaged, such as, for example, the one illustrated in figures 6 to 10 in connection with the second preferred embodiment of the hair styling device 1, 1' according to the invention.

[0043] The hair styling device 1' illustrated in figures 7 to 10Forming a blow-dry hairbrush, the blow-dry head 6 advantageously has an external shape substantially similar to that of a conventional hairbrush. As such, the blow-dry head 6 extends longitudinally along a fourth axis DD' parallel to, and preferably coinciding with, the second axis BB' of rotation of the head relative to the handle 2. As illustrated, the blow-dry head 6 is also arranged relative to the handle 2 such that the second axis BB' of rotation of the blow-dry head 6 coincides with the first axis AA' of longitudinal extension of the handle 2.

[0044] As illustrated in particular in the Figure 10The blower head 6 may include a nozzle body 19, which is not in the form of a separate part mounted in the outer casing 20 of the blower head 6, but is instead 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-fitting or screwing). Said nozzle body 19 then advantageously extends along a fifth axis EE' orthogonal to the fourth longitudinal extension axis DD' of the blower head 6, between, on the one hand, a first nozzle end forming the first air outlet 7 of the blower head 6 and, on the other hand, a second opposing nozzle end forming the second air outlet 8 of the blower head 6.

[0045] According to one embodiment, the outer casing 20 may include at least one clip (not shown) positioned along the edge of the outer casing 20 so as to come into contact with the hair during the styling operation. This clip is preferably heated, or at least capable of transferring some of the heat from the drying airflow circulating in the blower head 6 to the hair. For example, the clip may be made of a heat-conducting material, such as a metallic material (steel, aluminum, etc.), and be in direct contact with the drying airflow circulating inside the nozzle 19. For example, the clip may extend through the entire thickness of the outer casing 20 and protrude, on one side, inside the nozzle 19 to be in contact with the drying airflow and, on the other side, outside to be in contact with the hair.Such a clip allows for the formation of a raised edge, preferably heated, which comes into contact with the hair during styling, thus creating a curling effect. This curling effect refers to the formation of harmonious waves in a strand of hair, similar to the waves created by rubbing curling ribbon against a scissor blade to make pretty gift packages. Preferably, the outer casing has two clips positioned opposite each other, approximately parallel, and arranged on either side of the fourth axis DD' so that the curling effect can be achieved in any direction when using the styling tool.

[0046] The first air outlet 7 of the blower head 6 advantageously has an opening of generally oblong shape, elongated, in a general direction parallel to the fourth axis DD' of longitudinal extension of the blower head 6 ( Figure 7 ). The second air outlet 8, for example, has an opening made up of a multitude of orifices distributed between rows of brush bristles (or pins) with which the blower head 6 is advantageously equipped, each of these orifices being generally circular in shape ( figures 6 And 8 ).

[0047] In this second particular embodiment, the hair styling device 1' also includes a deflector 13 to guide the airflow generated by the blower module 5 from the guide channel 12 of the handle 2 alternately to one or the other of the first 7 and second 8 air outlets, depending on the position of the blower head 6. As illustrated in Figure 15, the deflector 13 preferably comprises a bent tubular element 21, in this case formed from a frustoconical tube section closed at one end and whose lateral wall has 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 AA' of extension of the latter.

[0048] As illustrated in the figure 5The nozzle body 19 advantageously includes an air inlet orifice, with dimensions conjugate to those of the bent tubular element 21 of the deflector 13, and through which said bent tubular element 21 enters the nozzle body 19, along the second axis BB' of rotation of the blower head 6. The respective configurations and arrangements of the bent tubular elements 21 and nozzle body 19 of the hair styling device 1' according to the second embodiment of the figures 6 to 10 are advantageously similar, if not identical, to those described above in connection with the corresponding angled tubular element 21 and nozzle body 19 of the hairdressing appliance 1 according to the first embodiment of the figures 1 to 5 and produce essentially the same effects.

[0049] Advantageously, one or both of the first 7 and second 8 air outlets of the blower head may 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 velocity / flow rate profile of the airflow blown through the air outlet in question. For example, in the embodiments illustrated in the figures, the first air outlet 7, whose opening geometry is advantageously adapted for using the hair styling appliance 1,1' for drying / pre-drying hair, is provided with such deflector flaps 23. In the first embodiment of the figures 1 to 5 The deflector flaps 23 are advantageously made of the same material as the nozzle body 19. Alternatively, the deflector flaps 23 can be formed by a separate attached part, as in the second embodiment of the figures 6 to 10The second air outlet 8, whose opening geometry is preferentially adapted for use of the hair styling device 1,1' for styling assistance or hair styling purposes, is devoid of deflector flaps.

[0050] The hair styling device 1, 1' includes a heating element 24 designed to raise the temperature of the airflow generated by the blower module 5. Integrated within the hair styling device 1, 1', the heating element 24 can be arranged within the blower head 6 or within (i.e., inside) the handle 2 thereof. Advantageously, the heating element 24 is arranged (at least partially) within (i.e., inside) the handle 2, and even more advantageously within the guide channel 12 of said handle 2, as in the embodiments illustrated in the figures, so as to be interposed in the airflow generated by the blower module 5. Such a configuration notably reduces the size and weight of the blower head 6 and simplifies its design.This is typically an electric heating element, operating on the principle of the Joule effect, and preferably with a power rating greater than 500 W. Preferably, the heating element 24 comprises at least one electric heating element formed by a winding of a metallic conductive wire (for example, 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 shown) around an insulating core 25 (for example, mica) with a cruciform cross-section and provided, at its ends, with fixing fins. Advantageously, the hair styling appliance 1, 1' further comprises a thermal insulator 26, for example, a tubular piece 26 with a circular base, within which the heating element 24 is mounted, and which notably protects the user from the risk of burns by limiting the heating of the handle 2.As illustrated in the figures, the inner wall of the thermal insulation 26 can advantageously define all or part of the airflow guide channel 12 mentioned above.

[0051] The hair styling appliance 1, 1' also includes an electronic module 27. Not necessarily intended to be directly manipulated by the user, or even to be accessible by the user, the electronic module 27 is advantageously designed to interact (directly or indirectly) with all or part of the various functional components that the hair styling appliance 1 may include. It is typically a card, an electronic circuit, a printed circuit board (PCB) PCB" or a set of electrical, electronic or electromechanical components internal to the hair styling appliance 1, 1'. The electronic module 27 may be intended to provide a particular power supply (with, for example, a current filtering, transformation or rectification function), to provide control, command or regulation of the operation of one or more of the functional components of the hair styling appliance 1, 1'. Optionally, said electronic module 27 may include components such as an electric battery, a display, one or more microcontrollers, etc.The electronic module 27 can optionally be connected to a number of sensors distributed throughout the hair styling device 1, 1' and intended to measure and monitor physical quantities related to the operation of the latter (temperatures, voltages and electrical currents, air flow speeds / rates, rotation speed of the fan 14 of the blower module 5, etc.), in order to optimally control the operation of the various functional components of the hair styling device 1, 1'.

[0052] The electronic module 27 is an electronic module designed to control the operation of the blower module 5 and / or the heating element 24 of the hair styling appliance 1, 1'. Indeed, the blower module 5 and / or the heating element 24 of the hair styling appliance 1, 1' may require, for their respective operation and depending on the technologies used, the implementation of one (or more) specific electronic control module(s) or board(s).

[0053] 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 specific power supply and / or regulation circuit (power, temperature, etc.) for said heating element 24. In the preferred case where the blower module 2 includes a brushless electric motor 11, as envisaged above, the control of said brushless electric motor 11 can advantageously be ensured by the electronic module 27. As such, the electronic module 27 can then be designed to ensure, in particular, the commutation of the electric current in the stator windings (phase control) of the motor 11 according to data from position sensors (for example, Hall effect), the self-regulation of the rotational speed, etc.

[0054] Preferably, as in the first preferred embodiment illustrated in figures 1 to 5An electronic module 27 is advantageously arranged within the blower head 6, preferably outside the airflow circulating within the latter. Advantageously, the blower head 6 includes a dedicated compartment 28 suitable for receiving said electronic module 27.

[0055] Such an arrangement helps to limit the overall size of the hair styling appliance 1, 1', particularly in the case where the electronic module 27 is designed to control the operation of the blower module 5 and / or the heating element 24 and these are arranged outside the blower 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 it, the electronic module 27 is then advantageously located away from the heating element 24 and / or the blower module 5 that it controls, which makes it possible to limit as much as possible the size of the handle 2 and / or the blower module 5 connected to it.

[0056] However, given the rotating nature of the blower 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 blower head 6 (or any other functional part of the hair styling appliance 1, 1' which would be connected to the electronic module 27 and which would be arranged outside the blower head 6) and, on the other hand, the electronic module 27 arranged in the blower head 6.

[0057] That is why, as in the first preferred embodiment illustrated in figures 1 to 5 The electronic module 27 is preferably mounted within the blower head 6 so as to remain stationary relative to the blower module 5 and / or the heating element 24 during the rotation of the blower head 6. As such, and as illustrated in the example in the figure 5The nozzle body 19 may be provided with an additional orifice 29, which is opposite the air inlet orifice through which the bent tubular element 21 of the deflector 13 enters the nozzle body 19. At this additional orifice 29, a portion of the bent tubular element 21 is either flush with or protrudes from the nozzle body 19, to which the electronic module 27 may be attached, either directly or via a specific bracket 30. Of course, other suitable mounting configurations may be considered. For example, depending on its dimensions, the electronic module 27 could be mounted on the back of the bent tubular element 21 of the deflector 13.

[0058] 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 blower head 6 can be advantageously and very simply made, for example using conventional electrical conductors (not shown), without risk of damaging the electrical wires by twisting or requiring the use of complex mobile electrical connection methods (such as a swivel connector). The manufacturing cost of the hair styling appliance 1 is thus reduced and its reliability increased.

[0059] Being housed within the blower head 6, and although preferentially positioned outside the airflow circulating through it, the electronic module 27 is susceptible to a significant temperature increase when the airflow generated by the blower module 5 is heated by the heating element 24 before being blown out of the device 1 by the blower head 6. Furthermore, even if the heating element 24 is not activated or the hair styling device does not include such a heating element, the electronic module 27 is susceptible, during its normal operation, to overheating itself, particularly due to the electric current passing through it. In all cases, this results in a high risk of malfunction, or even total failure, of the electronic module 27 if its temperature is not controlled and exceeds a certain tolerance threshold.

[0060] In a particularly advantageous manner, the hair styling device 1, 1' may therefore include a bypass channel 31 designed to capture part of the airflow 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 ensure the collection and diversion of part of the forced airflow produced by the blower module 5 - before said airflow is, if necessary, heated by the heating element 24 - in order to guide and blow the part of the airflow thus taken as close as possible to the electronic module 27 to ensure forced cooling of the latter.

[0061] 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 thereof, said bypass channel 31 preferably extends at least partially into the handle 2. The bypass channel 31 is thus advantageously integrated into the handle 2. Even more preferably, the hair styling device 1, 1' may 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 AA' of extension of the latter.

[0062] 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 airflow (fresh, i.e. not yet heated 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 blower head 6.

[0063] As illustrated in the example to the figure 5The bypass channel 31 can be formed, along all or part of the length of the handle 2, by a free space provided between an inner wall of the handle 2 and an outer wall of the tubular thermal insulation 26. Such a design also advantageously allows the handle 2 to be cooled, which improves the user comfort of the hair styling appliance 1, 1'. The bypass channel 31 can advantageously extend, at the level of the blower head 6, inside a double-walled wall 32 forming a back of the angled tubular element 21, and then through the support 30, mentioned above, by means of which the electronic module 27 is fixed to the angled tubular element 21.

[0064] Advantageously, the hair styling device 1, 1' can further include a reinjection circuit for the portion of the airflow captured in the (main) airflow blown by the blower head 6, so that after contributing to the cooling of the electronic module 27, the portion of the airflow captured by the bypass channel 31 can itself be blown towards the user's hair via the air outlet(s) 7, 8 of the blower head 6. In this way, the cooling of the electronic module 27 does not significantly affect the airflow rate generated by the blower module 5 and blown by the blower head 6. For example, the nozzle body 19 of the blower head 6 may be provided with an orifice (not shown) for reinjecting the portion of the captured airflow directly into the nozzle body 19, preferably downstream of the bent tubular element 21 of the deflector 13.

[0065] Alternatively (or complementaryly), the outer casing 20 of the blower head 6 can be provided with vents (or equivalent) through which all or part of the captured airflow can escape from the blower head 6, and therefore from the hair styling device 1, 1'. Thus, the portion of the airflow used to cool the electronic module 27 can be expelled outside the hair styling device 1, 1' without impacting (or at least without significantly impacting) the temperature of the (main) airflow blown by the blower head 6 towards the user's hair.

[0066] Typically, said bypass channel 31 can be sized to allow the passage of an air flow of between 1 and 10 m³ / h, to allow efficient cooling of the electronic module 27.

[0067] According to one variant, included in the embodiments illustrated in the figures, the hair styling appliance 1, 1' includes manual means 33 for the user to adjust the operation of the blower module 5 and / or the heating element 24. These are adjustment means, for example of the toggle switch, push button and / or slide or dial type, which the user can directly use to electrically activate / deactivate the hair styling appliance 1, 1' and to change the rotation speed of the fan 14 of the blower module 5, and therefore the speed / flow rate of the air blown by the blower head 6, and / or the heating temperature of the heating element 24.Such manual adjustment means, known as such, may be positioned, for example, at the handle 2 or at the blower module 5, when the latter is assembled to the first end 3 of the latter as illustrated in the figures.

[0068] According to another variant (not illustrated), the hair styling device 1, 1' may include automatic means for adjusting the operation of the blower module 5 and / or the heating element 24, which automatic adjustment means (automatically) link the operation of the blower module 5 and / or the heating element 24 to the position occupied by the blower head 6 relative to the handle 2. In other words, these are adjustment means on which the user acts not directly, but indirectly by means of rotating the blower head 6 relative to the handle 2.The said automatic adjustment means thus cooperate with the blower module 5 and the heating element 24 (where applicable, via the electronic module 27 mentioned above) in order to automatically modify their respective operation in response to a change, made by the user, in the position of the blower head 6 relative to the handle 2.

[0069] Such automatic control means may be formed from any means otherwise known as such and adapted to such an automatic control function. For example, said automatic control means may include, in particular, one or more switches or contactors (electrical, optical, mechanical, or magnetic), and / or one or more potentiometers, and / or one or more position sensors of the blower head 6 relative to the handle 2. Typically arranged at the interface between the blower head 6 and the handle 2, and electrically connected to the blower module 5 and / or the heating element 24 (where applicable, via the electronic module 27 mentioned above), such automatic control means may be activated or deactivated depending on the position of the blower head 6 relative to the handle 2, thereby modifying the operation of the blower module 5 and the heating element 24.In this way, it is advantageously possible to provide that each of the said first and second positions of the blower head 6 corresponds to a different predefined setting of the operation of the blower module 5 and / or the heating element 26, and preferably to a different predefined setting of the operation of both the blower module 5 and the heating element 24.

[0070] The automatic control means may preferably be designed and configured so that the first position of the blower head 6 corresponds to a first speed F1 and a first temperature T1 of the airflow blown by the blower head 6 (via the first air outlet 7 of the latter). Conversely, the automatic control means may preferably be designed and configured so that the second position of the blower head 6 corresponds to a second speed F2 and a second temperature T2 of the airflow blown by the blower head 6 (via the second air outlet 8 of the latter).

[0071] More preferably, the first F1 and second F2 airflow velocities of the blown air head 6 may be different from each other, and the first T1 and second T2 airflow temperatures of the blown air head 6 may be different from each other. However, it remains conceivable that the automatic control means may be designed and configured to cooperate with the blower module 5 and the heating element 24 in order to automatically maintain an identical speed or temperature of the blown airflow regardless of the position of the blown air head 6, and therefore regardless of the selected air outlet 7, 8 and the geometry of its opening.

[0072] Thus, each of the first and second positions of the blower head 6 can be automatically associated with a speed-temperature combination of the blown airflow, which can be advantageously predefined and optimized for a particular use of the hair styling appliance 1, 1'. The first speed F1 and first temperature T1 of the airflow blown by the blower head 6 can be advantageously predefined and optimized for using the hair styling appliance 1 for hair drying. The first position of the blower head 6 can thus advantageously correspond to a hair-drying position. Conversely, the second speed F2 and second temperature T2 of the airflow blown by the blower head 6 can be advantageously predefined and optimized for using the hair styling appliance 1 for hair styling.The said second position of the blower head 6 can thus advantageously correspond to a position called for styling (hairdressing).

[0073] In this respect, and by way of illustration and not limitation, the first temperature T1 of the airflow blown by the blower head 6 may advantageously be between 64 and 104 °C, and even more advantageously equal to 84 °C. The first velocity F1 of the airflow blown by the blower head 6 may advantageously be between 35.7 km / h and 99.0 km / h, and even more advantageously equal to 72.8 km / h. The second temperature T2 of the second airflow blown by the blower head 6 may advantageously be between 60 and 100 °C, and even more advantageously equal to 80 °C. The said second speed F2 of the airflow blown by the blower head 6 may advantageously be between 78.1 km / h and 208.3 km / h, and even more advantageously equal to 138.9 km / h.

[0074] Advantageously, said automatic adjustment means may be designed and configured so that said first position of the blower head 6 corresponds to a first operating power P1 of the heating element 24 and a first rotation speed V1 of the fan 14 of the motor-fan group 10 of the blower module 5. Said first power P1 and first rotation speed V1 may advantageously be predefined and optimized for use of the hair styling appliance 1, 1' for hair drying purposes.

[0075] In this respect, and by way of illustration and without limitation, the first operating power P1 of the heating element 24 may advantageously be between 1,000 W and 2,000 W, and even more advantageously be equal to 1,500 W. The first rotational speed V1 of the fan 14 may advantageously be between 13,000 rpm and 17,000 rpm, and even more advantageously be equal to 15,000 rpm. Depending on the dimensions of the blower module 5, such a first rotational speed V1 of the fan 14 may advantageously correspond to a flow rate Q1 of the first airflow blown by the blower head 6 that is between 50 m³ / h and 90 m³ / h, and even more advantageously equal to 70 m³ / h.

[0076] Conversely, said automatic adjustment means may be advantageously designed and configured so that said second position of the blower head 6 corresponds to a second operating power P2 of the heating element 24 and a second rotation speed V2 of the fan 14 of said motor-fan unit 10. Said second power P2 and second speed V2 may be advantageously predefined and optimized for use of the hair styling appliance 1 for the purpose of assisting in hair styling. In this respect, and by way of illustration and not limitation, the second operating power P2 of the heating element 24 may advantageously be between 500 W and 1,500 W, and even more advantageously be equal to 1,000 W. The second rotation speed V2 of the fan 14 may advantageously be between 14,000 rpm and 18,000 rpm, and even more advantageously equal to 16,000 rpm.According to the sizing of the blower module 5, such a second speed V2 of rotation of the fan 14 may advantageously correspond to a flow rate Q2 of the second airflow blown by the blower head 6 which is between 30 m 3< / h and 70 m 3< / h, and even more advantageously equal to 50 m 3< / h.

[0077] Optionally, in the case where the hair styling device 1' forms a blow-dry brush, according to 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 the same.

[0078] A hair styling device according to such a variant of the invention is thus even simpler and more intuitive for the user to operate, since the operation of the blower module 5 and / or the heating element 24 is advantageously predefined, preset, according to the position of the blower head 6 relative to the handle 2. It is therefore possible, during the manufacture of the hair styling device 1, 1', to define in advance the best settings of the hair styling device 1, 1' according to the position of the blower head 6. The result will therefore be advantageously optimized for the user of the hair styling device 1, 1', regardless of their level of hairdressing experience.

[0079] It is also advantageously possible to provide that the hair styling appliance 1, 1' is designed so that its blower head 6 is capable of occupying a third position relative to the handle 2, distinct from the said first and second positions, and in which the automatic means for regulating the operation of the blower module 5 and / or the heating element 24 are designed to stop the operation of the hair styling appliance 1, 1'. Thus, stopping the operation of the hair styling appliance 1, 1' can advantageously be achieved by a rotation of the blower head 6 by the user, without the user necessarily needing to act directly on any general on / off switch.

[0080] Preferably, the hair styling appliance 1, 1' is designed and configured so that said third position (or stop position) corresponds to a position of the blower head 6 relative to the handle 2 that is intermediate between said first and second positions. For example, if the hair styling appliance 1, 1' is designed so that moving the blower head 6 from said first position to said second position corresponds to a rotation of the blower head 6 through an angle of 180° around the second axis B-B', said third position may correspond, in a manner particularly intuitive for the user, to a rotation of the blower head 6 through an angle of 90° around said second axis B-B', from one and / or the other of said first and second positions.

[0081] Whether the means for adjusting the operation of the blower module 5 and / or the heating element 24 are manual or automatic, the hair styling appliance 1, 1' preferably includes, in addition to said adjustment means, a means for manually activating / deactivating the heating element 24. Thus, regardless of the position of the blower head 6 (and therefore the air outlet 7, 8 selected), and regardless of the chosen setting of the operation of the blower module 5 and / or the heating element 24, it remains possible at any time for the user to stop the operation of the heating element 24 alone, so as to blow only a flow of fresh air (i.e. not heated by the heating element 24) onto the hair.

[0082] For example, such a means of manually activating / deactivating the heating element 24 can consist of a conventional electrical switch, of the toggle or push-button type, positioned on the handle 2 of the hair styling appliance 1, 1', and connected between the heating element 24 and its power supply circuit. Alternatively, and more advantageously, and as illustrated in the example to figures 1 to 5The means for manually activating / deactivating the heating element 24 includes a mechanical rocker selector 34, which is mounted on the surface of the handle 2 and is mechanically connected, by means of a rod (not shown) housed inside the handle 2, to a miniaturized switch 35 arranged within the blower module 5, itself assembled at the first end 3 of the handle 2. By thus relocating part of the means for manually activating / deactivating the heating element 24, more space is gained within the handle 2, in particular for arranging the heating element 24.

[0083] In the embodiments illustrated in the figures and described above, the hair styling device 1, 1' is preferably designed so that the user moves the blow-dry head 6 from one position to another by holding the handle 2 of the hair styling device 1, 1' with one hand and grasping the blow-dry head 6 with the other hand in order to impart a rotational movement to it around its axis of rotation BB' relative to the handle 2. However, according to variants not illustrated, it is perfectly conceivable that the rotation of the blow-dry head 6 is motorized, for example by means of an electric motor controlled by a dedicated switch positioned at the handle 2, or simply mechanized, for example by means of a trigger and cam system. In this case, the user can easily grip the handle 2 and rotate the blower head 6 using only one hand.

[0084] The operation and use of device 1.1' are, for example, as follows.

[0085] With the blower head 6 of the device 1,1' initially in its first position relative to the handle 2, the user grasps the handle 2 of the device 1,1' with one hand, preparing to position the device 1,1' so that the first air outlet 7 of its blower head 6 is directed towards their damp hair. The user then activates the manual control means 33 for the operation of the blower module, and preferably also for the operation of the heating element of the device 1,1', so that a forced flow of air, preferably warm, is blown towards their hair through the first air outlet 7 of the blower head 6.

[0086] Then, after using the device 1,1' for the desired time, for example until their hair reaches a certain level of drying or pre-drying, the user grasps the blower head 6 with their other hand to rotate it around its axis of rotation BB' relative to the handle 2 and position the blower head 6 in its second position. The airflow is then blown through the second air outlet 8 of the blower head 6. By positioning the device 1,1' so that the second air outlet 8 of the blower head 6 is directed towards their hair, the user can, for example, now use the styling tool 1,1' to style their hair.
