HAIR STYLISH WITH A BLOW HEAD WITH OFFSET AIR GUIDE PLATES

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 hairdressing appliances designed to blow a flow of air in order to dry and / or facilitate the shaping of hair.

[0002] In the field of hair styling tools, blow-dry brushes are already known, designed to blow a stream of air towards the hair during brushing. Such devices are generally equipped with internal air deflectors designed to guide the airflow generated by an integrated blower module towards the device's air outlet. However, the aerodynamic efficiency of these blow-dry brushes can be improved, particularly when the air outlet is large. Indeed, a certain spatial heterogeneity is observed in the blown airflow, especially in terms of flow rate, which leads to uneven treatment of the hair depending on its position relative to the air outlet during brushing.

[0003] We also know of multifunctional hair styling tools designed to blow air onto the hair using different airflow patterns to perform various drying and / or styling techniques with a single device. For example, there are handheld hair dryers whose nozzle has an air outlet to direct a forced stream of hot or cold air onto the user's hair. The forced airflow follows a single path within the device until it exits through this air outlet.To modify the airflow pattern of these hair dryers, additional accessories, either detachable or fixed, are generally provided at the air outlet. These accessories typically modify the effective airflow cross-section and / or the direction of the airflow, thus defining different airflow patterns adapted to specific hair drying and / or styling techniques. While these well-known hair dryers are generally satisfactory, they do have some drawbacks. In particular, switching between airflow patterns requires the user to assemble / disassemble accessories, or to manipulate a pre-mounted accessory at the air outlet. This can sometimes be tedious, which detracts from the ease of use and ergonomics of the device. IlThere is also a significant risk of burns when handling the accessory(ies), as well as a possible risk of losing the accessories, when they are not simply stored out of reach and inaccessible to the user when the latter wishes to use them.

[0004] To address these issues, a new hair styling device has recently been proposed whose blowing head has separate first and second air blowing outlets, to blow an airflow out of the device, typically according to different first and second blowing modes.The device in question further includes a blower module for initiating said airflow, as well as an air direction element arranged inside the blower head, the blower head and the air direction element being mounted movable relative to each other between a first configuration in which the air direction element directs the initiated airflow towards the first air blower outlet (for example for operation of the device in "blower brush" mode), and a second configuration in which the air direction element directs the initiated airflow towards the second air blower outlet (for example for operation of the device in "hair dryer" mode).While such a multifunctional hair styling device has a number of advantages in relation to the aforementioned problems, it has been observed that such a device can still be improved in terms of aerodynamic efficiency, and in particular in terms of controlling the homogeneity of the airflow blown by the device according to the selected air blowing outlet.

[0014] The invention relates to a hair styling device 1, that is, a device intended to allow a user, male or female, to perform one or more hair treatment operations on their own hair (or that of a third party) in order to dry and / or style it. More specifically, the hair styling device 1 according to the invention, a non-limiting embodiment of which is illustrated by example in the figures, is at least designed to blow a stream of air towards the hair in order to dry and / or facilitate the styling of said hair.

[0015] The hair styling device 1 according to the invention is preferably portable, meaning that at least part, and preferably all, of the hair styling device 1 is designed to be grasped and manipulated by hand. The hair styling device 1 is preferably a portable power tool, intended to be connected to the electricity distribution network for power, for example, via a power cord with a plug at one free end (not shown). However, it is alternatively conceivable, without departing from the scope of the invention, that the hair styling device 1 incorporates batteries for power, possibly rechargeable.The hair styling appliance 1 is preferably intended for use in a domestic setting by a user (male or female) without any particular professional skills in hairdressing, i.e., in terms of drying, styling, or shaping hair. Preferably, the hair styling appliance 1 is designed for the user to use on themselves, i.e., on their own hair. However, it is perfectly conceivable that the hair styling appliance 1 may be designed for use by the user on the hair of another person.

[0016] In the embodiment illustrated in the figures, the hair styling appliance 1 constitutes a multifunctional hair styling appliance (appliance "2 in1”), which is designed to be used alternately as a blow dryer and as a hairdryer. However, the invention is not limited to any particular hair styling appliance, whether multifunctional or not, and is applicable to any hair styling appliance designed to blow a stream of air onto hair as part of one or more hairstyling operations. For example, the hair styling appliance could thus be solely a hairdryer or solely a blow dryer, without departing from the scope of the invention.

[0017] As illustrated in the figures, the hair styling appliance 1 advantageously includes a handle 2 (or grip) for manual handling, intended to be grasped by the hand, for example, by the user, to operate the appliance 1. The handle 2 typically extends between a first end 3 and a second opposite end 4, preferably longitudinally along an axis AA' of average extension. The handle 2 advantageously has a slender, elongated shape so that it can be grasped fully by the user.

[0018] The hair styling device 1 includes a blower head 5 for blowing a flow F of air out of the device 1, towards the hair. Typically connected to the handle 2, the blower head 5 has at least one (first) air outlet 6 for blowing said flow F of air out of the device 1. According to the invention, the blower head 5 includes (first) air deflectors 7A, 7B, 7C (or "air deflector elements"" to guide the airflow F out of the hair styling appliance 1 through said first air outlet 6. Forming (first) outlet air deflectors, said first air deflectors 7A, 7B, 7C are arranged for example in said first air outlet 6 or, as illustrated in the figures, inside the blower head 5 and upstream of the first air outlet 6. Typically, the first air deflectors 7A, 7B, 7C form fins, flaps or "blades", and may have a substantially flat shape or, as in the embodiment illustrated in the figures, a curved shape.Arranged so as to be interposed in the airflow F circulating in the blower head 5 towards the outside of the hair styling device 1, each of the first air deflectors 7A, 7B, 7C of the blower head 5 advantageously extends along a first average direction from a leading edge to an opposite trailing edge, and from a first lateral end to a second lateral end along a second average direction which is secant to said first average direction.

[0019] According to the invention, said first air deflectors 7A, 7B, 7C are arranged in a plurality of rows RA, RB, RC, substantially parallel to a first direction X-X', and therefore substantially parallel to each other. As illustrated by example in figures 15 to 17 And 19said rows RA, RB, RC are adjacent and offset from each other along said first direction XX' so that first air deflectors 7A, 7B, 7C of one of said rows RA, RB, RC are neither contiguous nor aligned along a second direction YY' substantially orthogonal to said first direction X-X', with first air deflectors 7A, 7B, 7C of the other of said rows RA, RB, RC adjacent.In other words, the blower head 5 comprises at least two rows RA, RB, RC of first air deflectors 7A, 7B, 7C, which are adjacent and parallel to each other, and the first air deflectors 7A, 7B, 7C of a row RA, RB, RC considered are not only distinct and distant from the first air deflectors 7A, 7B, 7C of another row RA, RB, RC which is adjacent to said row RA, RB, RC considered, but they are further not aligned with first air deflectors 7A, 7B, 7C of said adjacent row RA, RB, RC along said second direction Y-Y'. There is therefore an asymmetry between two adjacent rows RA, RB, RC of first air deflectors 7A, 7B, 7C, and a discontinuity of said first air deflectors 7A, 7B, 7C between each other.

[0020] It has indeed been observed that, thanks to this very specific arrangement of the (first) air deflectors 7A, 7B, 7C, it is possible to obtain excellent spatial homogeneity of the airflow F supplied by said (first) air outlet 6, in terms of flow rate and velocity, particularly when the latter is large, and this without resorting to a large number of (first) air deflectors 7A, 7B, 7C and / or to very complex configurations thereof. Advantageously, such a gain in homogeneity contributes significantly to the aerodynamic performance of the hair styling device 1 and to the effectiveness of the hair treatment performed with it. Furthermore, when the hair styling device 1 includes a heating element to heat said airflow F, as will be discussed later, such a gain in homogeneity allows better management of the temperature profile of the airflow F and of heat exchanges with the blower head 5.Indeed, a higher flow rate of hot air at one point than at another along the airflow path F leads to a less uniform temperature across the entire first air outlet 6. The improved uniformity of the airflow F achieved by the specific arrangement of the (first) air deflectors 7A, 7B, 7C described above results in improved spatial uniformity of the airflow F in terms of temperature. This prevents excessive localized heating of certain parts or sections of the blower head 5, thus contributing to improved safety, robustness, and reliability of the hair styling appliance 1. Furthermore, this increased spatial uniformity of the airflow in terms of temperature contributes to the effectiveness of hair treatment and optimizes the user's perception of the temperature of the blown airflow F.

[0021] The aforementioned advantages are even greater when, preferably, as in the embodiment illustrated in the figures, said rows RA, RB, RC are adjacent and offset from one another along said first direction XX' so that none of the first air deflectors 7A, 7B, 7C of each of the rows RA, RB, RC are contiguous, nor aligned along said second direction YY' substantially orthogonal to said first direction X-X', with a first air deflector 7A, 7B, 7C of another of said rows RA, RB, RC which is adjacent.

[0022] Preferably, the first air deflectors 7A, 7B, 7C are fixed. In other words, the first air deflectors 7A, 7B, 7C are stationary relative to the first air outlet 6 of the blower head 5. Their position and spatial orientation are therefore fixed by design and cannot be changed. This contributes, in particular, to the simplicity of the aerodynamic design of the hair styling device 1 and to the reliability of its operation. Advantageously, as in the embodiment illustrated in the figures, the first air deflectors 7A, 7B, 7C of each of the aforementioned rows RA, RB, RC are arranged equidistant from each other. Advantageously, the rows RA, RB, RC of first air deflectors 7A, 7B, 7C together present a plane of symmetry Ps which extends parallel to said first direction X-X', or which contains the latter, and which is orthogonal to said second direction Y-Y'.This allows, in particular, a simplified design and manufacture of the first air deflectors 7A, 7B, 7C, and contributes to excellent spatial homogeneity of the supply airflow F. Advantageously, each of the first air deflectors 7A, 7B, 7C extends along a median plane Pm1A, Pm1B, Pm1C of respective extension. Preferably, in terms of simplicity of aerodynamic design and manufacture in particular, the first air deflectors 7A, 7B, 7C of the same row RA, RB, RC, are arranged with their median planes Pm1A, Pm1B, Pm1C of extension arranged parallel to each other (. figures 15 to 17 And 19 ).

[0023] Preferably, said rows RA, RB, RC of first air deflectors 7A, 7B, 7C are odd in number, preferably three. Said first air deflector elements 7A, 7B, 7C are therefore preferably arranged in an odd number of rows RA, RB, RC, and preferably in three rows RA, RB, RC, substantially parallel to said first direction X-X'. In this way, it is advantageously possible to mechanically reinforce the first air deflectors 7A, 7B, 7C using a plurality of lines 8A, 8B (first) spacers 8, and not a single line of spacers, which connect on one side the first air deflector elements 7A, 7B, 7C of one of the rows RA, RB, RC, and which connect on the other side the first air deflector elements 7A, 7B, 7C of one of the adjacent rows RA, RB, RC, without one of the said lines 8A, 8B of first spacers 8 being arranged in the center of the air flow F.Advantageously, the lines 8A, 8B of the first spacers 8 can extend longitudinally in a mean direction which is inscribed in a plane parallel to the first direction XX' and orthogonal to the second direction Y-Y'. The robustness of the hairdressing appliance 1 is thereby improved, with a limited impact on aerodynamic performance.

[0024] Preferably, the blow-drying head 5 includes a mechanical hair engagement element 9, designed to come into contact with the hair (when using the styling appliance 1) to shape the hair, or at least to assist in shaping it. Designed and configured to interact mechanically with the hair, particularly for brushing, setting, styling, and / or combing, the mechanical hair engagement element 9 typically comprises a plurality of bristles, tufts of bristles, and / or prongs and / or teeth, which are arranged projecting from an external surface of the blow-drying head 5. The latter thus advantageously forms a styling or brushing head.In use of the hair styling appliance 1, the mechanical hair engagement element 9 can be applied to and against the hair to help shape it through mechanical interaction between the hair and the mechanical hair engagement element 9. Advantageously, as in the embodiment illustrated in the figures, the blower head 5 has at least one first face 10 that carries the first air outlet 6 and the mechanical hair engagement element 9. The hair styling appliance 1 thus preferentially forms, at least according to one of its operating modes, a blower brush intended to be applied against the hair to subject it to mechanical action through interaction with the mechanical hair engagement element 9, coupled with the application of the airflow F, which may be hot.

[0025] More preferably, as in the embodiment illustrated in the figures, the first air outlet 6 comprises a plurality of air outlet orifices, i.e., a plurality of air outlet portions, which air outlet orifices are carried by and / or arranged between teeth, prongs, and / or brush bristles comprising the mechanical engagement element 9 of the hair. For example, said air outlet orifices may each be formed by a (straight or curved) slot arranged between teeth, prongs, and / or brush bristles. Thus, the airflow F can be optimally directed towards the hair when the hair is in contact with the mechanical engagement element 9 of the hair during a styling operation.

[0026] Advantageously, as in the embodiment illustrated in the figures, the first air outlet 6 extends longitudinally substantially along an axis BB' of average longitudinal extension of the blower head 5, which contributes in particular to rapid and efficient hair treatment in a limited number of passes of the styling appliance 1 against said hair. Preferably, the first direction XX' is oriented substantially parallel to the axis BB' of average longitudinal extension of the blower head 5. The first air outlet 6 then advantageously extends laterally substantially in a direction parallel to the second direction Y-Y'. Thus, the first air outlet 6 has a generally elongated shape along the axis BB' of average longitudinal extension of the blower head 5 and the first direction XX' of extension of the rows RA, RB, RC of the first air deflectors 7A, 7B, 7C.For example, said first air blow outlet 6 may then comprise a plurality of air blow outlets, each in the form of a slot (for example curved), as mentioned above, and which are arranged in a stepped manner along the average longitudinal extension axis BB' of the blow head 5.

[0027] More particularly advantageously, in the case where the blower head 5 has a first face 10 which carries the first air blower outlet 6 and a mechanical engagement element 9 of the hair, as envisaged above and as in the embodiment illustrated in the figures, the first air blower outlet 6 extends longitudinally along the average longitudinal extension axis BB' of the blower head 5 over a length which is preferably at least equal to half, and preferably even at least equal to two-thirds, of a respective length along which the mechanical engagement element 9 of the hair extends respectively longitudinally along the average longitudinal extension axis BB' of the blower head 5.

[0028] The hair styling device 1 typically includes a blower module 11 (or "motor-fan unit") to initiate the airflow F, i.e., to produce the airflow F, from ambient air in the environment of the hair styling device 1. Preferably, the blower module 11 is integrated within the hair styling device 1 itself. In this case, the hair styling device 1 is advantageously provided with an air inlet 12, through which ambient air can be drawn by the blower module 11 in order to be blown towards the hair via at least said first air outlet 6. The blower module 11, which typically includes at least one fan driven by an electric motor, can advantageously be arranged within the blower head 5 or within the handle 2, or be assembled to the handle 2 at the second end 4 thereof.More preferably, however, the blower module 11 is assembled to the handle 2 at its second end 4, so that the blower module 11 advantageously extends the handle 2 beyond its second end 4. Advantageously, the blower head 5 is connected to the handle 2 at its first end 3. In the case where the blower module 11 is arranged within the handle 2 or, more preferably, is assembled to the handle 2 at its second end 4, the hair styling device 1 advantageously includes an air guide channel 13 arranged, at least partially, inside the handle 2 to guide and channel the airflow F initiated by the blower module 11 to the blower head 5.

[0029] The blow-dry head 5 can be designed to be removably connected to the handle 2, allowing the user to separate it from the handle, for example, to clean or replace it. Alternatively, as illustrated in the figures, the blow-dry head 5 is designed to remain permanently connected to the handle 2 and is therefore not intended (under normal use) to be detached from the handle by the user. This simplifies both the design and the use of the hair styling appliance 1.

[0030] Preferably, the hair styling device 1 also includes a heating element for raising the temperature of the airflow F, which is advantageously initiated by the blower module 11. Typically integrated within the hair styling device 1, the heating element is advantageously arranged to be interposed in the airflow F initiated by the blower module 11. As in the embodiment illustrated in the figures, the heating element is advantageously positioned inside the air guide channel 13 arranged in the handle 2. The heating element is typically an electric heating element, comprising a heating electrical resistance formed of an electrically conductive wire (not shown) wound around an insulating core 14. Alternatively, the heating element could be housed in the blower head 5, although this would reduce the compactness of the latter.Advantageously, the hair styling appliance 1 includes means for the user to manually control and / or adjust the electrical operation of the hair styling appliance 1, and in particular the blower module 11 and / or the heating element, if applicable. These are adjustment means, for example, toggle switches, push-button switches, and / or slide or dial dimmers, as illustrated in the figures, which the user can directly operate to electrically switch the hair styling appliance 1 on and off and to change the rotational speed of the blower module 11's fan, and thus the speed / flow rate of the airflow F blown by the hair styling appliance 1, and / or the heating temperature of the heating element, if applicable.Such manual control / adjustment means 15 can be positioned, for example, on the handle 2 or on the blower module 11, when the latter is assembled to the second end 4 of the handle 2 as in the example illustrated in the figures. The hair styling appliance 1 may also optionally include a hot / cold air switch (not shown), for example arranged on the handle 2, preferably at its first end 3, to control the switching on and / or off of the heating element.

[0031] As in the embodiment illustrated in the figures, the hair styling appliance 1 advantageously includes an air direction element 16 ("air distribution element", or "air deflection element"), for directing and distributing the airflow F initiated by the blower module 11 at least towards the first air outlet 6 of the hair styling appliance 1. Advantageously arranged in the blower head 5, said air direction element 16 comprises: an air inlet 17, preferably a single one, which is connected to the blower module 11, i.e., which is in aerodynamic communication with the latter, to collect the air flow F initiated by the blower module 11, and an air direction outlet 18, preferably a single one, to direct the air flow F out of the air direction member 16.

[0032] In other words, said air direction member 16 is positioned or arranged in, or defined within, the blower head 5, and is designed to deflect the path of the airflow F generated by the blower module 11 in order to supply at least said first air blower outlet 6. Preferably, said air direction outlet 18 is designed and configured to direct the airflow F out of the air direction member 16 in an average exit direction that is secant to (or at least arranged at an angle to) an average inlet direction of the airflow F into the air direction member 16 via said air inlet 17.In other words, as illustrated in the figures, the air direction outlet 18 of the air direction member 16 is preferably designed and configured so that the airflow F, which enters through the air inlet 17 of the air direction member 16 along an average inlet direction, then exits through said air direction outlet 18 along an average outlet direction that is secant to (or at least arranged at an angle to) said average inlet direction. This notably allows for the arrangement of the blower module 11 outside the blower head 5, in a manner that is not aligned with at least said first air blower outlet 6.In the case where the blower module 11 is arranged in the handle 2 or at the second end 4 of the handle 2, as in the embodiment illustrated in the figures, the air inlet 17 of the air direction member 16 is advantageously connected to the air guidance channel 13 of the handle 2, as mentioned previously, in order to collect the air flow F initiated by the blower module 11. Preferably, the air direction member 16 forms an air direction duct (or "air deflection duct", or "plug"), which advantageously extends the air guidance channel 13 beyond the first end 3 of the handle 2.

[0033] In view of the above, the said first air deflectors 7A, 7B, 7C are therefore designed and configured to guide outwards from the blower head 5, via the first air blower outlet 6, the initiated airflow F which is directed towards the first air blower outlet 6 from the air direction outlet 18 of the air direction member 16.

[0034] In terms of spatial homogenization of the airflow F blown out of the hair styling device 1, it is advantageous to ensure that the rows RA, RB, RC form, in particular: at least one central row RB, the first air deflectors 7B of which have a concave face (generally) oriented against the direction of the airflow F circulating in the air direction member 16 from the air inlet 17 of the latter, and at least two lateral rows RA, RC, arranged on either side of said at least one central row RB, and the first air deflectors 7A, 7C of which have a convex face (generally) oriented against the direction of the airflow F circulating in the air direction member 16 from the air inlet 17 of the latter.

[0035] More advantageously, as illustrated in the figures, the rows RA, RB, RC of the first air deflectors 7A, 7B, 7C are odd in number and, more specifically, form at least one central row RB and at least two lateral rows RA, RC as defined above. For example, as in the embodiment illustrated in the figures, said rows RA, RB, RC are three in number and form one central row RB and two lateral rows RA, RC as defined above.

[0036] As in the embodiment illustrated in the figures, the air direction member 16 preferably comprises a side wall 19 (airtight) extending along an average longitudinal axis CC' of the air direction member 16 between a first end 20 that carries or defines the air inlet 17 of the air direction member 16 and a second opposite closed (and therefore airtight) end 21. Advantageously, the air direction outlet 18 of the air direction member 16 is provided through, or at least delimited by, the side wall 19 of the air direction member 16 and extends longitudinally along the average longitudinal axis CC' of the air direction member 16 (but not necessarily parallel to said average longitudinal axis CC').As illustrated in the figures, said side wall 19 preferentially defines a hollow internal shape whose cross-section narrows from the first end 20 towards the second end 21 of said side wall 19. Thus, the air direction member 16 advantageously forms an air direction duct, defined by said side wall 19, with a generally conical or frustoconical internal shape. In other words, the air direction member 16 advantageously comprises a hollow tube with a generally conical or frustoconical internal shape, defined by said side wall 19. This hollow tube typically has an axis of revolution that is advantageously formed by, or parallel to, the average longitudinal axis CC' of the air direction member 16.The first end 20 of said lateral wall 19 thus defines a large base of the overall frustoconical internal shape, through which the airflow F enters the air direction member 16. Such a hollow internal shape, whose cross-section narrows from the first end 20 towards the second end 21 of the lateral wall 19, advantageously allows for homogenization of the airflow profile F circulating inside the air direction member 16, and thus further improves the aerodynamic performance of the hairdressing device 1. The average longitudinal extension axis CC' of the air direction member 16 is advantageously coincident with, being collinear with, the average longitudinal extension axis BB' of the blower head 5.The axes B-B', CC' of respective average longitudinal extension of the blower head 5 and the air direction member 16 are advantageously collinear with the axis AA' of average longitudinal extension of the handle 2.

[0037] Even more advantageously, the air direction outlet 18 of the air direction member 16 has a useful cross-section that narrows towards the second end 21 of the side wall 19 of the air direction member 16, as illustrated in the example in the figure 13 in particular. This contributes advantageously to homogenizing the profile of the air flow F which exits the air direction member 16 through said air direction outlet 18, and therefore to further improving the aerodynamic performance of the hairdressing device 1.

[0038] Preferably, as illustrated in the figures, the air direction outlet 18 of the air direction member 16 is provided with a plurality of air deflectors 22, called "primary air deflectors", to straighten the air flow F exiting the air direction member 16 through the air direction outlet 18 from the air inlet 17 of the air direction member 16. Said primary air deflectors 22 are distinct from said first air deflectors 7A, 7B, 7C of the blower head 5, which are advantageously called in return "secondary first air deflectors 7A, 7B, 7C". It is understood that the terms "primary" and "secondary" advantageously refer, here and in what follows, to the order in which the air deflectors 7A, 7B, 7C, 22 concerned are arranged in consideration of the direction of circulation of the air flow F in the hairdressing device 1.Thus, during operation of the hair styling unit 1, the airflow F initiated by the blower module 11 is first guided and straightened at the outlet of the air direction unit 16 by the primary air deflectors 22, before being guided and straightened by the first secondary air deflectors 7A, 7B, 7C and blown out of the hair styling unit 1 towards the hair. The use of such primary air deflectors 22 in conjunction with the aforementioned first secondary air deflectors 7A, 7B, 7C further enhances the spatial homogeneity of the blown airflow F.

[0039] Advantageously, the primary air deflectors 22 are fixed. In other words, said primary air deflectors 22 are stationary relative to the air outlet 18 of the air direction member 16. Their position and spatial orientation are therefore fixed by design and cannot be changed. This contributes in particular to the simplicity of the aerodynamic design of the hair styling unit 1 and to the reliability of its operation. Arranged so as to be interposed in the airflow F circulating in the blower head 5 towards the outside of the hair styling unit 1, each of the primary air deflectors 22 of the air direction member 16 advantageously extends along a first average direction from a leading edge to an opposite trailing edge, and from a first lateral end to a second lateral end along a second average direction that intersects said first average direction.Advantageously, as illustrated by example in the figures, said primary air deflectors 22 are arranged in at least one row, which preferably extends substantially parallel to the aforementioned first direction XX'. Advantageously, said at least one row of primary air deflectors 22 extends along the longitudinal extension axis CC' of the air direction element 16 (but not necessarily parallel to said mean longitudinal extension axis CC').

[0040] Even more advantageously, the primary air deflectors 22 are arranged in a single row. Thus, as seen in the example at the figure 13Each of the primary air deflectors 22 advantageously extends continuously through (or opposite) the air direction outlet 18 of the air direction member 16, from its first lateral end, which is connected to a lateral peripheral edge of the air direction outlet 18, to its second lateral end, which is connected to an opposite lateral peripheral edge of the air direction outlet 18. Advantageously, each of the primary air deflectors 22 extends along a respective median plane Pm2. Preferably, for the sake of simplicity in aerodynamic design and manufacturing, the primary air deflectors 22 are arranged with their median planes Pm2 parallel to each other.

[0041] For reasons similar to those mentioned previously in connection with the first air deflectors 7A, 7B, 7C, it is advantageous to plan, as seen in the example at the figure 13in particular, that the primary air deflectors 22 of such a single row include at least one central portion which has a concave face oriented (generally) against the direction of the airflow F circulating in the air direction member 16 from said air inlet 17, that is to say oriented (generally) towards the second end 21 of the side wall 19 of the air direction member 16, and at least two lateral portions, arranged on either side of said at least one central portion, and which each have a convex face oriented against the direction of the airflow F circulating in the air direction member 16 from said air inlet 17, that is to say oriented (generally) towards the second end 21 of the side wall 19 of the air direction member 16.

[0042] In order to further improve the aerodynamic performance of the hair styling unit 1, it is particularly advantageous to provide that, as illustrated in the figures, at least a portion (if not all) of the primary air deflectors 22 are arranged inside the air direction member 16, within the hollow inner shape of the latter. Thus, at least a portion of the leading edges of the primary air deflectors 22 are arranged within the hollow inner shape, so as to intercept at least a portion of the airflow F circulating within the air direction member 16 from the first end 20 to the second end 21 of the lateral wall 19 thereof. Even more advantageously, as can be seen in the figure 14in particular, the leading edges of the primary air deflectors 22 are arranged in a progressively offset manner relative to each other along the longitudinal extension axis CC' of the air direction member 16 and towards the second end 21 of the lateral wall 19 of the latter, so that the leading edge of the, or each of the, primary air deflector(s) 22 positioned furthest from the air inlet 17 is arranged closer to an average extension axis of said hollow internal form than is the respective leading edge of the, or each of the, primary air deflector(s) 22 positioned closest to the air inlet 17.This contributes advantageously to the control of the homogeneity of the air flow F in terms of flow rate, by preventing the primary air deflector(s) 22 positioned closest to the air inlet 17 from intercepting too large a part of the air flow F, which could lead to a "blockage" of the flow F and an insufficient residual air flow F at the primary air deflector(s) 22 positioned furthest from the air inlet 17.

[0043] Preferably, the hair styling unit 1 is designed and configured such that at least a portion of a plurality of said primary air deflectors 22 is arranged in alignment with a plurality of said first secondary air deflectors 7A, 7B, 7C, at least when the hair styling unit 1 is in an operating mode in which the airflow F is intended to be blown out of the hair styling unit 1 through the first air outlet 6. In other words, a plurality of said first secondary air deflectors 7A, 7B, 7C are arranged in continuity with at least a portion of at least some of the primary air deflectors 22, taking into account the direction of flow of the airflow F. This particular technical feature, and the associated effects and advantages, will be explained below.

[0044] Advantageously, as in the embodiment illustrated in the figures, the blower head 5 has at least one second air outlet 23, that is, at least one other air outlet, which is separate from the first air outlet 6, for blowing the airflow F out of the hair styling device 1. The blower head 5 thus has a plurality of said air outlets 6, 23, which are separate from one another. As in the embodiment illustrated in the figures, the blower head 5 advantageously has a first face 10 which, as considered above, has said first air outlet 6, and a second face 24 which has said second air outlet 23. Said first and second faces 10, 24 constitute different, and preferably opposite, faces of the hair styling device 1.Advantageously, the first and second air outlets 6, 23 exist simultaneously (i.e., they are both permanently present on the hair styling appliance 1), and not alternately. Typically, the hair styling appliance 1 comprises a housing, for example made of plastic, an external face of which defines at least a portion of said first and second faces 10, 24 of the blower head 5. Said housing has an external surface (defined by said external face) which defines at least a portion of an external surface of the hair styling appliance 1.

[0045] In return, the air direction unit 16 and the blower head 5 are advantageously mounted to move relative to each other at least between a first air direction configuration (or "first air distribution configuration") in which the air direction device 16 directs the initiated airflow F towards (and preferably only towards) the first air outlet 6 ( figure 6 ), according to a first blowing method ( figures 1 to 3 , 6 , 7 , 10 And 21 ), and a second air direction configuration (or "second air distribution configuration") in which the air direction device 16 directs the initiated airflow F towards (and preferably only towards) the second air blower outlet 23, reciprocally therefore according to a second blowing mode ( Figures 5 , 8 , 9 , 12 And 22 ).

[0046] The air direction member 16 is therefore advantageously designed and configured to define, or at least to help define, different paths of the airflow F within the hair styling device 1 according to the air direction configuration it occupies relative to the blower head 5. Advantageously, the air direction member 16 is configured to divert the airflow F exiting the air guide channel 13 described previously alternately towards one or the other of the first and second air blower outlets 6, 23, according to the air direction configuration it occupies relative to the blower head 5.Preferably, the air direction member 16 includes a (single and) unique air direction outlet 18, as mentioned above, to direct the air flow F, through said air direction outlet 18, to the first air blow outlet 6 when the air direction member 16 is in said first air direction configuration (. figures 1 to 3 , 6 , 7 , 10 And 21 ) and conversely towards the second air blower outlet 23 when the air direction device 16 is in said second air direction configuration ( Figures 5 , 8 , 9 , 12 And 22). In the said first air direction configuration, the air direction outlet 18 of the air direction member 16 is thus in aerodynamic communication with the first air blower outlet 6, while in the said second air direction configuration, the said air direction outlet 18 is reciprocally in aerodynamic communication with the second air blower outlet 23. Preferably, the air direction member 16 comprises a (single and) unique air inlet 17, as mentioned above, which is connected to the blower module 11 to collect the air flow F initiated by the latter, and this regardless of the blowing mode considered.

[0047] Preferably, as already mentioned previously and as in the embodiment illustrated in the figures, the air direction outlet 18 is designed and configured so that the airflow F entering through the air inlet 17 exits through the air direction outlet 18 along an average outlet direction that is secant to (or at least arranged at an angle to) an average inlet direction along which the airflow F enters the air direction member 16 through said air inlet 17 ( figures 6 And 8 ), and therefore regardless of the air direction configuration in which the air direction element 16 is located relative to the blower head 5.

[0048] As in the embodiment illustrated in the figures, the first blowing mode (first air direction configuration of the air direction member 16) advantageously corresponds to an operating mode of the hair styling appliance 1 in "blowing brush" mode. In this respect, the first face 10 of the blowing head 5 carries said first air blowing outlet 6 and a mechanical hair engagement element 9, which are advantageously designed and configured as described above. Preferably, as in the embodiment illustrated in the figures, the second blowing mode (second air direction configuration of the air direction member 16) corresponds to an operating mode of the hair styling appliance 1 in "hair dryer" mode. In this respect, the second air blowing outlet 23 preferably has a single, preferably single, air blowing opening.For example, as illustrated in the figures, the air outlet opening is oblong or oval in cross-section and extends, for example, longitudinally along the average longitudinal extension axis BB' of the blower head 5, to blow the airflow F in the form of an air blade. Alternatively, the air outlet opening could, for example, be circular in cross-section, to blow the airflow F in a substantially cylindrical or frustoconical shape. Preferably, the second air outlet 23 is defined by a nozzle 25, for example, fixed (non-removable) or, conversely, removable, at least a portion of which projects from a surface of the second face 24 of the blower head 5, typically projecting from the external surface of the housing. Thus, the second air outlet 23 is advantageously easily identifiable by the user.

[0049] Regardless of the configuration of the second air outlet 23, the blower head 5 preferably includes (second) air deflectors 26 (or " air deflector elements"") to guide the airflow F out of the hair styling appliance 1 through said second air outlet 23, when the air direction member 16 is therefore in said second air direction configuration. As can be understood, said second air deflectors 26 are distinct from said first air deflectors 7A, 7B, 7C. Forming (second) outlet air deflectors, said second air deflectors 26 are arranged for example in said second air outlet 26 or, as illustrated in the figures, inside the blower head 5 and upstream of the second air outlet 26. Typically, the second air deflectors 26 form fins, flaps or "blades", and can each have a substantially flat shape or, as in the embodiment illustrated in the figures, a curved shape.The said second air deflectors 26 are therefore advantageously designed and configured to guide outwards from the blower head 5, via the second air blower outlet 23, the initiated air flow F which is directed towards the second air blower outlet 23 from the air direction outlet 18 of the air direction member 16.

[0050] In the same way that the first air deflectors 7A, 7B, 7C of the blower head 5 can be described as "secondary first air deflectors 7A, 7B, 7C," the second air deflectors 26 of the blower head 5 can advantageously be called "secondary second air deflectors 26" when the air direction outlet 18 of the air direction member 16 includes primary air deflectors 22 as described above. It is understood that the second secondary air deflectors 26 are then distinct from the primary air deflectors 22.

[0051] Thus, in operation of the hair styling device 1 according to said second blowing mode (second air direction configuration of the air direction element 16), the airflow F initiated by the blower module 11 is advantageously first guided, straightened, at the outlet of the air direction element 16 by the primary air deflectors 22, before being guided, straightened, by the second secondary air deflectors 26 and thus blown out of the hair styling device 1 towards the hair via the second air blowing outlet 23. The implementation of said second secondary air deflectors 26, preferably in association with said primary air deflectors 22, advantageously contributes to further improving the spatial homogeneity of the blown airflow F.

[0052] Preferably, the second air deflectors 26 are fixed. In other words, these second air deflectors 26 are stationary relative to the second air outlet 23 of the blower head 5. Their position and spatial orientation are therefore fixed by design and cannot be changed. This contributes, in particular, to the simplicity of the aerodynamic design of the hair styling device 1 and to the reliability of its operation. Arranged so as to be interposed in the airflow F circulating in the blower head 5 towards the outside of the hair styling device 1, each of the second air deflectors 26 of the blower head 5 advantageously extends along a first average direction from a leading edge to an opposite trailing edge, and from a first lateral end to a second lateral end along a second average direction that intersects said first average direction.Advantageously, as illustrated in the figures, the second air deflectors 26 are arranged in at least one row. More advantageously, the second air deflectors 26 are arranged in a single row. Advantageously, as in the embodiment illustrated in the figures, the second air deflectors 26 are arranged equidistant from each other along an extension direction of the row(s) of second air deflectors 26. Such a configuration is particularly well suited to cases where the second blowing mode is a "hair dryer" mode, and the air outlet of the second air outlet 23 has an oblong, oval, or circular cross-section, as described above. Advantageously, each of the second air deflectors 26 extends along a respective median plane Pm3.Preferably, in terms of simplicity of aerodynamic design and manufacturing in particular, the second air deflectors 26 are arranged with their median planes Pm3 arranged parallel to each other.

[0053] Preferably, as already discussed above, the hair styling device 1 is designed and configured so that at least a portion of a plurality of said primary air deflectors 22 of the air distribution element 16 is arranged aligned with a plurality of said first secondary air deflectors 7A, 7B, 7C of the blowing head 5 when the air direction element 16 is in said first air direction configuration (first blowing mode).

[0054] Preferably, the hair styling appliance 1 is designed and configured such that at least a portion of a plurality of said primary air deflectors 22 of the air distribution element 16 is arranged aligned with a plurality of said secondary air deflectors 26 when the air direction element 16 is in said second air direction configuration (second blowing mode). In this case, said portion of primary air deflectors 22 is advantageously a central portion of said primary air deflectors 22.

[0055] More particularly preferred, as in the embodiment illustrated in the figures, said hair styling appliance 1 is designed and configured such that: at least a portion of a plurality of the primary air deflectors 22 of the air direction outlet 18 of the air direction member 16 is arranged aligned with a plurality of the first secondary air deflectors 7A, 7B, 7C when the air direction member 16 is in the first air direction configuration ( figures 6 , 7 And 19 ), and at least a portion of a plurality of the primary air deflectors 22 of the air direction outlet 18 of the air direction member 16 is respectively arranged aligned with a plurality of the secondary second air deflectors 26 when the air direction member 16 is in the second air direction configuration ( figures 8 , 9 And 20 ).

[0056] In other words, in the first air direction configuration, at least a portion of several of the primary air deflectors 22 is aligned with at least one of the corresponding secondary first air deflectors 7A, 7B, 7C. Conversely, in the second air direction configuration, at least a portion of several of the primary air deflectors 22 is aligned with at least one of the corresponding secondary second air deflectors 26.

[0057] A plurality of said first secondary air deflectors 7A, 7B, 7C is thus advantageously arranged in continuity with at least a portion of at least some of said primary air deflectors 22, taking into account the direction of airflow F. Advantageously, when said at least portion of primary air deflectors 22 is thus arranged aligned with said plurality of first secondary air deflectors 7A, 7B, 7C (first air direction configuration / first blowing mode), the trailing edges of the primary air deflectors 22 concerned are then arranged opposite the respective leading edges of the corresponding first secondary air deflectors 7A, 7B, 7C concerned ( figures 6 , 7 And 19). Conversely, a plurality of said secondary second air deflectors 26 is thus advantageously arranged in continuity with at least a portion of at least some of said primary air deflectors 22, taking into account the direction of airflow F. Advantageously, when said at least portion of primary air deflectors 22 is arranged aligned with said plurality of secondary second air deflectors 26 (second air direction configuration / second blowing mode), the trailing edges of the primary air deflectors 22 concerned are then arranged opposite the respective leading edges of said corresponding secondary second air deflectors 26 concerned ( figures 8 , 9 And 20 ).

[0058] Advantageously, when at least a portion of said plurality of primary air deflectors 22 is thus arranged aligned with said plurality of first secondary air deflectors 7A, 7B, 7C (first air direction configuration / first blowing mode), the median planes Pm2 of extension of the primary air deflectors concerned are then arranged coplanar with the respective median planes Pm1A, Pm1B, Pm1C of extension of the corresponding first secondary air deflectors concerned ( figures 6 , 7 And 19Advantageously, when at least a portion of said plurality of primary air deflectors 22 is reciprocally arranged aligned with said plurality of secondary second air deflectors 26 (second air direction configuration / second blowing mode), the median planes Pm2 of extension of the primary air deflectors concerned are then arranged coplanar with the respective median planes of extension Pm3 of the corresponding secondary second air deflectors concerned ( figures 8 , 9 And 20 ).

[0059] Thanks to each of the aforementioned characteristics, and even more so thanks to the combination of said characteristics, the hair styling appliance 1 advantageously forms a multi-mode (or "multifunctional") blowing device with a particularly simple and efficient aerodynamic design. The implementation of said primary air deflectors 22, said first secondary air deflectors 7A, 7B, 7C and second secondary air deflectors 7A, 7B, 7C, and their relative alignment as described above makes it possible in particular to optimize and homogenize, in a particularly efficient manner, the blowing of the airflow F out of the hair styling appliance 1 towards the hair, depending on the (first or second) air blowing outlet 6, 23 used.It is thus possible, in particular, as in the embodiment illustrated in the figures, to obtain an ergonomically designed hair styling device 1, offering at least two different first and second blowing modes in which the airflow F can be blown out of the hair styling device 1 towards the hair in a simple and efficient manner respectively according to first and second air blowing directions which are inclined with respect to, and in particular orthogonal to, the longitudinal extension axis AA' of the handle 2 of the hair styling device 1. In addition, the simplicity of the aerodynamic design of the hair styling device 1 advantageously facilitates its manufacture, and further contributes to its robustness and reliability.

[0060] Advantageously, in terms of design simplicity, as illustrated in the figures, the blower head 5 is preferably devoid of: of additional air deflectors (flaps or "blades") that would be arranged between the primary air deflectors 22 and the first secondary air deflectors 7A, 7B, 7C, respectively between the primary air deflectors 22 and the second secondary air deflectors 26, and / or of additional air deflectors (flaps or "blades") that would be arranged between the first secondary air deflectors 7A, 7B, 7C and the first air blow outlet 6, respectively between the second secondary air deflectors 26 and the second air blow outlet 23.

[0061] For example, as in the embodiment illustrated in the figures, the blower head 5 comprises three rows RA, RB, RC of first air deflectors 7A, 7B, 7C, each row comprising three first air deflectors 7A, 7B, 7C. Advantageously, the blower head 5 comprises a single row of second air deflectors 26 comprising five second air deflectors 26. Advantageously, the air direction outlet 18 of the air direction member 16 is provided with a single row of primary air deflectors 22 comprising two primary air deflectors 22.In a particularly advantageous manner, in said first air direction configuration of the air direction member 16 (or at least when the hair styling appliance 1 is intended to blow said air flow F through said first air blow outlet 6), at least a portion of each of the two primary air deflectors 22 is arranged aligned with at least one of the first (secondary) air deflectors 7A, 7B, 7C of at least one of the three rows RA, RB, RC of first secondary air deflectors 7A, 7B, 7C (. figure 19 in particular). Particularly advantageously, in said second air direction configuration of the air direction member 16, at least a portion of each of the two primary air deflectors 22 is arranged aligned with one of the five secondary second air deflectors 26 ( Figure 20 ).

[0062] In order to mechanically reinforce the primary air deflectors 22, the air direction member 16 preferably includes spacers 27 (“primary spacers”), which mechanically connect said primary air deflectors 22 to each other in pairs on the one hand, and to a peripheral edge of the air direction outlet 18 on the other hand ( figure 13 ). Even more preferably, said primary spacers 27 are arranged aligned along at least one line 27A of primary spacers 27, and possibly along two lines 27A, 27B of primary spacers 27, advantageously parallel to each other, as in the example illustrated in the figures, so as to simplify the design of the air direction member 16 and to limit the disturbance of the passage of the air flow F that could be caused by the presence of said primary spacers 27.

[0063] As previously mentioned, in order to mechanically reinforce the first air deflectors 7A, 7B, 7C, the blower head 5 may advantageously include first spacers 8 (or "secondary first spacers" as appropriate), which mechanically connect said first air deflectors 7A, 7B, 7C to each other in pairs. Preferably, said first spacers 8 are then arranged aligned along at least one line 8A, 8B of first spacers 8, and possibly along two lines 8A, 8B of first spacers 8, advantageously parallel to each other, as in the example illustrated in the figures. Optionally, in order to mechanically reinforce the second secondary air deflectors 26, the blower head 5 may advantageously include second spacers (or "second secondary spacers" as appropriate), which mechanically connect said second air deflectors 26 together.Preferably, the said second spacers are then arranged aligned along at least one line of spacers, and possibly along two lines of second spacers.

[0064] More preferably, the line(s) 27A, 27B of primary spacers 27 is arranged aligned, coplanar, in an alignment plane Pa1 with the corresponding line(s) 8A, 8B of first secondary spacers 8, in said first air direction configuration of the air direction member 16 or at least when the hair styling appliance 1 is intended to blow the air flow F through the first air blow outlet 6 ( figure 21). Conversely, one or each of the line(s) 27A, 27B of primary spacers 27 can advantageously be arranged aligned, coplanar, in a plane of alignment with one or one of the corresponding line(s) of secondary second spacers, in said second air direction configuration of the air direction member 16. Such an alignment of the lines of spacers advantageously contributes to limiting the disturbance of the passage of the air flow F that could be generated by the presence of said spacers.In general, the implementation of such first spacers 8 (secondary), primary spacers 27 and second spacers (secondary) advantageously allows the first air outlet 6, the air direction outlet 18 of the air direction member 16 and / or the second air outlet 23 to be dimensioned in such a way as to give the latter high useful air passage sections, typically in the preferred ranges mentioned below, while maintaining excellent mechanical robustness of said first air deflectors 7A, 7B, 7C (secondary), of said primary air deflectors 22 and / or of second air deflectors 26 (secondary).

[0065] To ensure optimal airflow F directed towards the hair, particularly in terms of air flow rate, the first air outlet 6 has a minimum total effective cross-section (i.e., the sum of the effective cross-sections of each portion of the first air outlet 6) that is preferably between 1 cm² and 20 cm², and even more preferably between 8 cm² and 15 cm². For the same reasons, the second air outlet 23 has a minimum total effective cross-section that is preferably between 1 cm² and 20 cm², and even more preferably between 8 cm² and 15 cm². Even more preferably, the first air outlet 6 and the second air outlet 23 have identical minimum total effective cross-sections.In turn, the air inlet 17 of the air direction member 16 preferably has a useful cross-section (or "useful air inlet cross-section") of between 1 cm² and 20 cm², and more preferably between 8 cm² and 15 cm². As for the air direction outlet 18 of the air direction member 16, it has a useful cross-section (or "useful air outlet cross-section") which is preferably between 1 cm² and 20 cm², and more preferably between 8 cm² and 15 cm².

[0066] The blowing head 5 advantageously comprises, as in the embodiment illustrated in the figures, a first portion of piping 28 provided for ensuring an aerodynamic connection of the air direction outlet 18 of the air direction unit 16 with the first air blower outlet 6 of the blower head 5 when the air direction unit 16 occupies the first air direction configuration, and a second portion of piping 29 provided for ensuring an aerodynamic connection of said air direction outlet 18 with the second air blower outlet 23 when the air direction unit 16 occupies the second air direction configuration.

[0067] As illustrated in the figures, the blower head 5 may include an internal ducting device 30, which defines at least in part the first and second ducting sections 28, 29, and which therefore constitutes a "two-way" internal ducting device (or "two-way distributor"). This internal ducting device 30 is advantageously fixed, immobile, relative to the first and second air blower outlets 6, 23 of the blower head 5. The air direction element 16 and the internal ducting device 30 of the blower head 5 are thus mounted to move relative to each other between the first and second air direction configurations. Thus, when the air direction element 16 is in the first air direction configuration ( figures 1 to 3 , 6 , 7 , 10 And 21), the air direction outlet 18 of the air direction member 16 is in aerodynamic communication with the first duct section 28 of the internal ducting device 30, and therefore with the first air supply outlet 6. Conversely, the air direction member 16 (for example, its side wall 19) then blocks the second duct section 29 of the internal ducting device 30. Conversely, when the air direction member 16 occupies the second air direction configuration ( Figures 5 , 8 , 9 , 12 And 22 ), the air direction outlet 18 of the air direction member 16 is in aerodynamic communication with the second portion of the duct 29, and therefore with the second air blower outlet 23. The air direction member 16 (for example, the side wall 19 of the latter) then closes the first portion of the duct 28 of the internal ducting device 30.

[0068] Preferably, the air direction element 16 is arranged at least partly within the internal ducting device 30, which helps to reduce the overall size of the blower head 5, and more generally the overall size of the hair styling appliance 1. Advantageously, the first air deflectors 7A, 7B, 7C (secondary) and / or the second air deflectors 26 (secondary) comprising the blower head 5 are supported by said internal ducting device 30 ( Figures 15 to 20Advantageously, as in the embodiment illustrated in the figures, the first duct section 28 has a useful air passage cross-section that decreases continuously towards the first air outlet 6. Conversely, the second duct section 29 advantageously has a useful air passage cross-section that decreases continuously towards the second air outlet 23. This advantageously contributes to facilitating the circulation of the airflow F towards the first air outlet 6 ( figure 21 ), respectively towards the second air blower outlet 23 ( Figure 22 ), and therefore to reduce the risk of air blockage and increased air pressure inside the blower head 5, as well as the risk of air (possibly hot) leaking into other parts of the blower head 5.

[0069] Different kinematic arrangements of the air direction element 16 and the blower head 5 can be considered, depending in particular on the shape and configuration of the air direction element 16. Preferably, however, for the sake of simplicity in the design and use of the hair styling appliance 1, the blower head 5 is fixedly connected to the handle 2 of the hair styling appliance 1, and the air direction element 16 is mounted to move relative to the blower head 5 and the handle 2 between the first and second air direction configurations. In order to simplify the design of the hair styling appliance 1 and improve its compactness, the air direction element 16 and the blower head 5 are preferably mounted to rotate and pivot about an axis DD' of rotation relative to each other between at least the first and second air direction configurations.Preferably, said axis DD' of rotation coincides with (collinear to), or at least parallel to, the axis CC' of longitudinal extension of the air direction member 16, which is itself advantageously coincides with (collinear to) the axis BB' of average longitudinal extension of the blower head 5. According to one variant (not illustrated), the air direction member 16 is fixed relative to the handle 2, and the blower head 5 is then mounted to rotate about said axis DD' of rotation relative to the air direction member 16 and the handle 2. According to another variant, implemented in the embodiment illustrated in the figures, the blower head 5 is fixed to the handle 2, and the air direction member 16 is mounted to rotate about said axis DD' of rotation relative to the blower head 5 and the handle 2.In accordance with the foregoing, this second variant proves preferable insofar as it contributes to making the hair styling device 1 simpler in design and use. In this case, the internal channeling device 30 mentioned above is itself advantageously fixedly connected to the handle 2 of the hair styling device 1, the air direction member 16 being advantageously arranged to rotate about the axis DD' of rotation within the internal channeling device 30 between the first and second air direction configurations.

[0070] To further improve the practicality and intuitiveness of the hair styling appliance 1, the first and second air outlets 6, 23 are preferably arranged opposite each other, on either side of a plane P1 in which is inscribed an average extension direction of the hair styling appliance 1 (or, where applicable, one of the average extension directions of the hair styling appliance 1). This average extension direction advantageously corresponds to an average extension direction of a portion of the hair styling appliance 1 that carries the first and second air outlets 6, 23. This average extension direction of the hair styling appliance 1 thus preferably corresponds to the average longitudinal extension axis BB' of the blower head 5.The first and second air outlets 6 and 23 are thus preferentially arranged opposite each other, on either side of a plane P1 in which the axis BB' of average longitudinal extension is inscribed. In this way, the first and second air outlets 6 and 23 are advantageously not simultaneously visible to the user when the latter looks directly at the first air outlet 6 and, respectively, the second air outlet 23.The user can easily use the hair styling device 1 alternately according to the first blowing mode or according to the second blowing mode, typically by a simple 180° rotation of the handle 2 of the hair styling device 1 to orient that of the said first and second air blowing outlets 6, 23 corresponding to the hair to be treated, in the preferential case where the blowing head 5 is fixedly connected to the handle 2 and where the air direction member 16 is mounted to rotate freely relative to the blowing head 5 and the handle 2.

[0071] Preferably, as mentioned previously, the first air outlet 6 extends longitudinally substantially along the average longitudinal extension axis BB' of the blower head 5. Conversely, as illustrated in the figures, the air outlet of the second air outlet 23, preferably a single one, extends longitudinally along the average longitudinal extension axis BB' of the blower head 5. This advantageously allows, as such (and therefore independently of the nature of the blowing modes in which the hair styling device 1 is designed to operate), a quick and efficient treatment of the hair in a limited number of passes of the hair styling device 1 against the hair.More advantageously, in the case where the blower head 5 has a first face 10 which carries the first air blower outlet 6 and a mechanical engagement element 9 of the hair, as envisaged above and as in the embodiment illustrated in the figures, the first air blower outlet 6 extends longitudinally along the average longitudinal extension axis BB' of the blower head 5 over a length which is preferably at least equal to half, and preferably even more at least equal to two-thirds, of a respective length along which the mechanical engagement element 9 of the hair extends respectively longitudinally along the average longitudinal extension axis BB' of the blower head 5.

[0072] Advantageously, the hair styling device 1 also includes a control system 31 for controlling each transition of the hair styling device 1 from one of the first and second air direction configurations to the other. The control system 31 is therefore designed to allow the user to alternately select one or the other of the blowing modes, that is, to control the transition of the hair styling device 1 from one blowing mode to another, and for example, from the first blowing mode to the second blowing mode and vice versa. In this respect, as in the embodiment illustrated in the figures, the control system 31 is advantageously connected to the air direction element 16 to control each transition of the air direction element 16 from one of the aforementioned first and second air direction configurations to the other.By operating the control system, the user can thus alternately select one or the other of the at least two different blowing modes of the hair styling appliance 1. The user can therefore advantageously choose through which of the first and second air outlets 6, 23 the airflow F will be blown out of the hair styling appliance 1, and thus select the operating mode of the hair styling appliance 1. The control system 31 is advantageously separate from the manual control and / or adjustment means 15 for the electrical operation of the hair styling appliance 1 and the hot / cold air switch, as described above, which the hair styling appliance 1 may optionally include.It is advantageous for the user to select one of the blowing modes while another blowing mode is selected, prior to the activation of the blower module 11 of the hair styling appliance 1. The control system 31 is advantageously integrated into the blower head 5 and is preferably positioned along the average longitudinal extension axis BB' of the latter. Preferably, at least a portion of an element of the control system 31 forms, or at least contributes to forming, the upper (free) end of the blower head 5. This allows for easy and intuitive activation of the control system by the user.

[0073] Advantageously, the control system 31 for changing the blow-drying mode of the hair styling appliance 1 includes a movable manual control element, for example a button 32 or a dial, to allow the user to operate the control system and thus manually select one or the other of the blow-drying modes. "Movable" is advantageously understood here to mean that the manual control element is capable of moving between at least two advantageously predefined positions and / or spatial orientations (relative to the rest of the hair styling appliance 1), typically by translation, rotation, and / or tilting under the effect of a manual mechanical action exerted on it by the user.Preferably, as illustrated in the figures, the manual control element is arranged at the level of the blower head 5, that is to say, it is carried by (or belongs to) the blower head 5, and not at the level of the handle 2. This limits the risk of unintentional manipulation of the manual control element by the hand of the user holding the handle 2. Even more preferably, the manual control element is arranged at such a distance from the handle 2 that it cannot be reached by a finger of the hand of the user holding the handle 2. Inaccessible by a finger of the hand of the user holding the handle 2, the manual control element remains, however, advantageously accessible by a finger of the other hand of the user.Even more preferably, as illustrated by example in the figures, said manual control organ is arranged substantially along an axis parallel to, or coinciding with, the average longitudinal extension axis BB' of the blowing head 5, so that it is accessible to the user from the top of the blowing head 5.

[0074] Advantageously, as illustrated in the figures, the control system 31 of the hair styling appliance 1 is a push-push button control mechanism 32 (or "push-push kinematic control mechanism", or "button control mechanism") push-push"), to control each transition of the hair styling appliance 1 from one blowing mode to another. Intended to be operated by the user, for example manually, the control system 31 is therefore designed and configured to transform each push exerted by the user (typically with a finger) on the button 32 of the control system 31 into a transition of the hair styling appliance 1 from one blowing mode to another, or at the very least, from one blowing mode to another. The button 32 of the control system 31 then advantageously forms the aforementioned manual control element.As in the embodiment illustrated in the figures, the push-push button control mechanism 32 is advantageously connected to the air direction element 16 to control each transition of the air direction element 16 from one of the first and second air direction configurations to the other. Thanks to such a push-push button control mechanism 32, the operation of the hair styling appliance 1 is particularly simple and intuitive, since reproducing a simple pushing action performed by the user against the button 32 of the control mechanism, each time in the same direction of push, controls each change in the blowing mode of the hair styling appliance 1.Each press of the control mechanism by the user on button 32 thus initiates a cyclical transition of the hair styling appliance 1 from a given initial blowing mode to a subsequent blowing mode, and so on, until it returns to the initial blowing mode after the control mechanism has been successively activated as many times as the hair styling appliance 1 has different blowing modes. Advantageously, said push-push button control system / mechanism 32 conforms, at least in its operating principle, to that described in documents WO-2022 / 263775 A1, WO-2022 / 263774 A1, WO-2023 / 118682 A1 and WO-2023 / 118683 A1 on behalf of SEB SA
