Description

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.

In the field of hairdressing appliances, blow-drying brush-type appliances are already known, designed to blow a flow of air towards the hair during a hair brushing operation. Such appliances are generally equipped with internal air deflectors designed to guide an air flow generated by an integrated blower module towards an air blowing outlet of the appliance. However, the aeraulic efficiency of these blow-drying brushes remains perfectible, in particular when the air blowing outlet has large dimensions. Indeed, a certain spatial heterogeneity of the blown air flow F is observed, in terms of flow rate in particular, which leads to heterogeneous treatment of the hair depending on its position with respect to the air blowing outlet during the brushing operation.

Multifunctional hairdressing appliances are also known, designed to blow a flow of air towards the hair using different blowing modes for carrying out various hair drying and/or styling techniques using a single appliance. For example, hand-held hair dryers are known, the blowing head of which has an air blowing outlet for directing a forced flow of hot or cold air towards the hair of a user. The forced air flow follows a single path within the appliance, until it emerges through said air blowing outlet. In order to modify the blowing mode of these hair dryers, additional accessories are generally provided, detachably or not, at the air outlet in order to typically modify the useful air passage section and/or the air blowing direction, and thus to define different blowing modes adapted to the implementation of particular hair drying and/or styling techniques. These known hair dryers, while generally satisfactory, nevertheless have certain drawbacks. In particular, switching the hair dryer from one blowing mode to another requires, on the part of the user, a assembly/disassembly of accessories, or an operation of handling a pre-assembled accessory at the air outlet. Such an operation can sometimes be tedious, which affects the ease of use of the device and its ergonomics. There 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 are inaccessible to the user when the latter wishes to use them.

To address these issues, a new hairdressing appliance has recently been proposed, the blowing head of which has first and second air blowing outlets that are distinct from each other, for blowing a flow of air out of the appliance, typically according to different first and second blowing modes. The apparatus in question further comprises a blower module for initiating said air flow, as well as an air directing member arranged inside the blowing head, the blowing head and the air directing member being mounted to be movable relative to each other between a first configuration in which the air directing member directs the initiated air flow towards the first air blowing outlet (for example for operation of the apparatus in "blowing brush" mode), and a second configuration in which the air directing member directs the initiated air flow towards the second air blowing outlet (for example for operation of the apparatus in "hair dryer" mode). Although such a multifunctional hairdressing appliance has a number of advantages with regard to the aforementioned issues, it has been observed that such a appliance also remains perfectible in terms of aeraulic efficiency, and in particular in terms of controlling the homogeneity of the air flow blown by the appliance according to the selected air blowing outlet.

The objects assigned to the invention therefore aim to propose a new hairdressing appliance with a more efficient aeraulic design.

The objects assigned to the invention therefore aim to propose a new hairdressing appliance which allows more effective hair treatment.

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

Another object of the invention is to propose a new hairdressing appliance which is particularly robust and reliable.

Another object of the invention is to propose a new multifunctional hairdressing appliance, which allows a user to easily and efficiently carry out a plurality of separate operations, without requiring the use of an external complementary hairdressing appliance.

Another object of the invention is to propose a new hairdressing appliance which is particularly ergonomic, easy and safe to use, in particular for a user without particular professional hairdressing skills.

The objects assigned to the invention are achieved by means of a hairdressing appliance comprising at least one blowing head which carries at least one first air blowing outlet for blowing an air flow out of the appliance, and which comprises first air deflectors for guiding the air flow out of the appliance via said first air blowing outlet, said appliance being characterized in that said first air deflectors are organized in a plurality of rows substantially parallel to a first direction, said rows being adjacent and offset from each other in said first direction so that first air deflectors of one of said rows are neither contiguous nor aligned in a second direction substantially orthogonal to said first direction, with first air deflectors of another of said adjacent rows.

The invention relates to a hairdressing appliance 1, that is to say an appliance intended to allow a user, man or woman, to carry out one or more treatment operations on his or her hair (or that of a third person) in order to dry and/or shape it. More specifically, the hairdressing appliance 1 according to the invention, a non-limiting embodiment of which is illustrated as an example in the figures, is at least designed to blow a flow of air towards the hair, in order to dry and/or facilitate the shaping of said hair.

The hairdressing appliance 1 according to the invention is preferably portable, that is to say that at least a part, and preferably the whole, of the hairdressing appliance 1 is designed to be grasped and manipulated by hand. The hairdressing appliance 1 is preferably a portable electric appliance, intended to be connected to the electricity distribution network to be electrically powered, for example by means of a power cord provided at a free end with an electrical connection plug (not illustrated). It is however alternatively conceivable, without departing from the scope of the invention, that the hairdressing appliance 1 incorporates electrical power supply batteries, possibly rechargeable. The hairdressing appliance 1 is preferably intended for use in a domestic setting by a user (male or female) without particular professional skills in hairdressing, that is to say in terms of drying, styling, or shaping hair. Preferably, the hairdressing appliance 1 is designed so that the user uses the hairdressing appliance 1 on himself, that is to say on his own hair. However, it is perfectly conceivable that the hairdressing appliance 1 is designed for use by the user on the hair of a third person.

In the embodiment illustrated in the figures, the hairdressing appliance 1 constitutes a multifunctional hairdressing appliance (“ 2 in 1 ” appliance), which is designed to be able to be used alternately as a blow-drying brush and as a hair dryer. The invention is however not limited to a particular hairdressing appliance, multifunctional or not, and finds its application for any hairdressing appliance designed to blow a flow of air towards hair in the context of one or more hairdressing operations on said hair. For example, the hairdressing appliance could thus constitute only a hair dryer or only a blow-drying brush, without departing from the scope of the invention.

As illustrated in the figures, the hairdressing appliance 1 advantageously comprises a handle 2 (or grip) for manual gripping, which is intended to be grasped by hand, and for example gripped, by the user, to manipulate the appliance 1. The handle 2 typically extends between a first end 3 and a second opposite end 4, preferably longitudinally along an axis A-A' of average extension. The handle 2 advantageously has a slender, elongate shape, so that it can be grasped by the user in the full hand.

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

According to the invention, said first air deflectors 7A, 7B, 7C are organized 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 in the example in figures 15 to 17 And 19 , said rows RA, RB, RC are adjacent and offset from each other in 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 adjacent rows RA, RB, RC. In other words, the blowing 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 also 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 them.

It has indeed been observed that, thanks to such a very particular arrangement of the (first) air deflectors 7A, 7B, 7C, it is possible to obtain excellent spatial homogeneity of the air flow F blown by said (first) air blowing outlet 6, in terms of flow rate and speed, in particular when the latter is of large size, and this without having to resort to a large number of (first) air deflectors 7A, 7B, 7C and/or very complex conformations of the latter. Advantageously, such a gain in homogeneity contributes significantly to the aeraulic performance of the hairdressing appliance 1 and to the effectiveness of the hair treatment carried out with the latter. In addition, when the hairdressing appliance 1 comprises a heating element for heating said air flow F, as will be discussed later, such a gain in homogeneity allows better management of the temperature profile of the air flow F and of the heat exchanges with the blowing head 5. Indeed, a higher hot air flow rate at a given location than at another location in the vein of the air flow F leads to a less homogeneous temperature across the entire first air blowing outlet 6. The improvement in the homogeneity of the air flow F provided by the particular arrangement of the (first) air deflectors 7A, 7B, 7C described above leads to an improvement in the spatial homogeneity of the air flow F in terms of temperature. This makes it possible to avoid excessive local heating of certain parts or portions of the blowing head 5, which contributes to improving both the safety of use of the hairdressing appliance 1 and its robustness and reliability. In addition, such a gain in spatial homogeneity of the air flow in terms of temperature contributes to the effectiveness of hair treatment, and to an optimization of the user's perception of the temperature of the blown air flow F.

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 each other along said first direction X-X' so that none of the first air deflectors 7A, 7B, 7C of each of the rows RA, RB, RC are either contiguous or aligned along said second direction Y-Y' 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.

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 blowing outlet 6 of the blowing head 5. Their position and spatial orientation are therefore fixed by construction and cannot be modified. This contributes in particular to the simplicity of the aeraulic design of the hairdressing appliance 1 and to the reliability of the operation of the latter. Advantageously, as in the embodiment illustrated in the figures, the first air deflectors 7A, 7B, 7C of each of said rows RA, RB, RC are arranged equidistant from each other. Advantageously, the rows RA, RB, RC of first air deflectors 7A, 7B, 7C together have 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 an excellent spatial homogeneity of the flow F of blown air. Advantageously, each of the first air deflectors 7A, 7B, 7C extends along a respective median plane Pm1A, Pm1B, Pm1C of extension. Preferably in terms of simplicity of aeraulic design and manufacturing 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 ).

Preferably, said rows RA, RB, RC of first air deflectors 7A, 7B, 7C are odd in number, more preferably equal to three. Said first air deflector elements 7A, 7B, 7C are therefore preferentially organized according to a number odd 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 the one hand the first air deflector elements 7A, 7B, 7C of one of the rows RA, RB, RC, and which connect on the other hand the first air deflector elements 7A, 7B, 7C of one of the adjacent rows RA, RB, RC, without one of said lines 8A, 8B of first spacers 8 being arranged in the center of the air flow F. Advantageously, said lines 8A, 8B of first spacers 8 can extend longitudinally in a mean direction which is inscribed in a plane parallel to said first direction XX' and orthogonal to said second direction Y-Y'. The robustness of the hairdressing appliance 1 is thereby improved, with a limited impact on the aeraulic performance.

Preferably, the blowing head 5 comprises a mechanical hair engagement element 9, which is intended to come into contact with the hair (in use of the hairdressing appliance 1) to shape said hair, or at least to help shape said hair. Designed and configured to interact mechanically with the hair, in particular to brush it, set it, style it and/or comb it, the mechanical hair engagement element 9 may typically comprise a plurality of bristles, tufts of bristles and/or spikes and/or teeth, which are arranged projecting from an external surface of the blowing head 5. The latter therefore advantageously forms a styling or brushing head. In use of the hairdressing appliance 1, the mechanical hair engagement element 9 can thus be applied to and against the hair to help shape the latter by mechanical interaction between the hair and the mechanical hair engagement element 9. Advantageously, as in the embodiment illustrated in the figures, the blowing head 5 has at least a first face 10 which carries the first air blowing outlet 6 and the mechanical hair engagement element 9. The hairdressing appliance 1 thus preferentially forms, at least according to one of its operating modes, a blowing brush intended to be applied against the hair to subject the latter to a mechanical action by interaction with the mechanical hair engagement element 9 coupled with an application of the air flow F, possibly hot.

Even more preferably, as in the embodiment illustrated in the figures, the first air blowing outlet 6 comprises a plurality of air blowing orifices, that is to say therefore a plurality of air blowing outlet portions, which blowing orifices are carried by and/or are arranged between teeth, pins and/or brush bristles that the mechanical hair engagement element 9 comprises. For example, said air blowing orifices may each be formed by a slot (straight or curved) arranged between teeth, pins and/or brush bristles. Thus, the air flow F can be blown optimally towards the hair when the latter is engaged with the mechanical hair engagement element 9 during a hairdressing operation.

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

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

The hairdressing appliance 1 typically comprises a blower module 11 (or “motor-fan unit”) to initiate the air flow F, i.e. . to produce the air flow F, from ambient air from the environment of the hairdressing appliance 1. Preferably, the blower module 11 is embedded within the hairdressing appliance 1 itself. In this case, the hairdressing appliance 1 is advantageously provided with an air inlet 12, through which ambient air can be sucked in by the blower module 11 in order to be blown towards the hair via at least said first air blowing outlet 6. The blower module 11, which typically comprises at least one fan driven by an electric motor, can advantageously be arranged within the blowing head 5 or within the handle 2, or even be assembled to the handle 2 at the second end 4 of the latter. More preferably, however, the blower module 11 is assembled to the handle 2 at the second end 4 of the latter, so that the blower module 11 advantageously extends the handle 2 beyond the second end 4 of the latter. Advantageously, the blower head 5 is connected to the handle 2 at the first end 3 of the latter. In the case where the blower module 11 is arranged within the handle 2 or, more preferably, is assembled to the handle 2 at the second end 4 of the latter, the hairdressing appliance 1 advantageously comprises an air guide channel 13 arranged, formed, at least partly inside the handle 2 to guide, channel, the air flow F initiated by the blower module 11 to the blower head 5.

The blowing head 5 may be designed to be removably connected, assembled, to the handle 2, so that the user can separate the blowing head 5 from the handle 2, for example to clean or replace the blowing head 5. Alternatively, as in the embodiment illustrated in the figures, the blowing head 5 is designed to remain permanently connected to the handle 2, and is therefore not intended (in normal use) to be dissociated from the handle 2 by the user. This simplifies both the design and the use of the hairdressing appliance 1.

Preferably, the hairdressing appliance 1 also comprises a heating element provided to raise the temperature of the air flow F, which is advantageously initiated by the blower module 11. Typically embedded inside the hairdressing appliance 1, the heating element is advantageously arranged so as to be interposed in the air flow 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 an electrical heating resistor 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, to the detriment, however, of the compactness of the latter. Advantageously, the hairdressing appliance 1 comprises means for manual control and/or adjustment 15, by the user, of the electrical operation of the hairdressing appliance 1, and in particular of the blower module 11 and/or of the heating element where applicable. These are adjustment means, for example of the rocker switch type, push button type and/or of the slide or thumbwheel type dimmers as in the example illustrated in the figures, on which the user can directly act in order to electrically activate/deactivate the hairdressing appliance 1 and to modify the rotation speed of the fan of the blower module 11, and therefore the speed/flow rate of the air flow F blown by the hairdressing appliance 1, and/or the heating temperature of the heating element where applicable. Such manual control/adjustment means 15 may be positioned, for example, at the handle 2 or at the blower module 11, when the latter is assembled at the second end 4 of the handle 2 as in the example illustrated in the figures. The hairdressing appliance 1 may further optionally comprise a cold air/hot air switch (not illustrated), for example arranged at the handle 2, preferably at its first end 3, to control switching on and/or switching off of the heating element.

As in the embodiment illustrated in the figures, the hairdressing appliance 1 advantageously comprises an air direction member 16 (“air distribution member”, or “air deflection member”), for directing, distributing, the air flow F initiated by the blower module 11 at least towards said first air blowing outlet 6 of the hairdressing appliance 1. Advantageously arranged in the blower head 5, said air direction member 16 comprises:

• an air inlet 17, preferably single, which is connected to the blower module 11, that is to say which is in air communication with the latter, to collect the air flow F initiated by the blower module 11, and
• an air direction outlet 18, preferably single, for directing the air flow F out of the air direction member 16.

In other words, said air directing member 16 is positioned or arranged in, or defined within, the blowing head 5, and is designed to deflect the trajectory of the air flow F generated by the blowing module 11 in order to supply at least said first air blowing outlet 6. Preferably, said air directing outlet 18 is designed and configured to direct the air flow F out of the air directing member 16 in a mean outlet direction which is secant to (or at least arranged in an inclined manner with respect to) a mean inlet direction of the air flow F into the air directing member 16 via said air inlet 17. In other words, as illustrated in the figures, the air directing outlet 18 of the air directing member 16 is preferentially designed and configured so that the air flow F, which enters via the inlet air 17 of the air direction member 16 in a mean inlet direction, then exits through said air direction outlet 18 in a mean outlet direction which is intersecting with (or at least arranged in an inclined manner relative to) said mean inlet direction. This makes it possible in particular to provide an arrangement of the blower module 11 outside the blower head 5, in a manner 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 guide channel 13 of the handle 2, as mentioned previously, to thus 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 “spool”), which advantageously extends the air guide channel 13 beyond the first end 3 of the handle 2.

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

• au moins une rangée RB centrale, dont les premiers déflecteurs d'air 7B présentent une face concave (généralement) orientée à l'encontre du sens du flux F d'air circulant dans l'organe de direction d'air 16 en provenance de l'entrée d'air 17 de ce dernier, et
• au moins de deux rangées RA, RC latérales, agencées de part et d'autre de ladite au moins une rangée RB centrale, et dont les premiers déflecteurs d'air 7A, 7C présentent une face convexe (généralement) orientée à l'encontre du sens du flux F d'air circulant dans l'organe de direction d'air 16 en provenance de l'entrée d'air 17 de ce dernier.

It is advantageous, in terms of spatial homogenization of the flow F of air blown out of the hairdressing appliance 1, to provide that the rows RA, RB, RC form more particularly:

• at least one central row RB, the first air deflectors 7B of which have a concave face (generally) oriented against the direction of the air flow F circulating in the air direction member 16 coming 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 air flow F circulating in the air direction member 16 coming from the air inlet 17 of the latter.

More advantageously still, as illustrated in the figures, the rows RA, RB, RC of first air deflectors 7A, 7B, 7C are odd in number and more particularly 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 a central row RB and two lateral rows RA, RC as defined above.

As in the embodiment illustrated in the figures, the air direction member 16 preferably comprises a side wall 19 (airtight) which extends along an axis CC' of average longitudinal extension of the air direction member 16 between a first end 20 which carries or defines the air inlet 17 of the air direction member 16 and a second opposite end 21 which is closed (and therefore airtight). Advantageously, the air direction outlet 18 of the air direction member 16 is arranged through, or is at least delimited by, the side wall 19 of the air direction member 16 and extends longitudinally along the axis CC' of average longitudinal extension of the air direction member 16 (but not necessarily parallel to said axis CC' of average longitudinal extension). As illustrated in example in the figures, said side wall 19 preferentially defines a hollow internal shape whose section narrows from the first end 20 towards the second end 21 of said side wall 19. Thus, the air direction member 16 therefore advantageously forms an air direction duct, defined by said side wall 19, of generally conical or frustoconical internal general shape. In other words, the air direction member 16 advantageously comprises a hollow tube of generally conical or frustoconical internal shape, defined by said side wall 19. Said hollow tube typically has an axis of revolution which is advantageously formed by, or parallel to, the axis CC' of average longitudinal extension of the air direction member 16. The first end 20 of said side wall 19 therefore defines a large base of the generally frustoconical internal general shape, via which the air flow F enters the air direction member 16. Such a hollow internal shape, the section of which narrows from the first end 20 towards the second end 21 of the side wall 19, advantageously makes it possible to homogenize the profile of the air flow F which circulates inside the air direction member 16, and therefore to further improve the aeraulic performance of the hairdressing appliance 1. The axis CC' of extension average longitudinal extension of the air direction member 16 is advantageously coincident with, collinear with, the axis BB' of average longitudinal extension of the blowing head 5. The respective axes B-B', CC' of average longitudinal extension of the blowing head 5 and of the air direction member 16 are advantageously collinear with the axis AA' of average longitudinal extension of the handle 2.

Even more advantageously, the air direction outlet 18 of the air direction member 16 has a useful section which tapers towards the second end 21 of the side wall 19 of the air direction member 16, as illustrated in the example in figure 13 in particular. This advantageously contributes to homogenizing the profile of the air flow F which leaves the air direction member 16 via said air direction outlet 18, and therefore to further improving the aeraulic performance of the hairdressing appliance 1.

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 flow F of air leaving the air direction member 16 via the air direction outlet 18 coming from the air inlet 17 of the direction member air 16. Said primary air deflectors 22 are distinct from said first air deflectors 7A, 7B, 7C of the blowing head 5, which are advantageously referred to in return as “first secondary 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 appliance 1. Thus, in operation of the hairdressing appliance 1, the air flow F initiated by the blower module 11 is first guided, straightened, at the outlet of the air direction member 16 by the primary air deflectors 22, before being guided, straightened, by the first secondary air deflectors 7A, 7B, 7C and blown out of the hairdressing appliance 1 in the direction of the hair. The implementation of such primary air deflectors 22 in association with said first secondary air deflectors 7A, 7B, 7C advantageously contributes to further improving the spatial homogeneity of the flow F of blown air.

Advantageously, the primary air deflectors 22 are fixed. In other words, said primary air deflectors 22 are immobile relative to the air direction outlet 18 of the air direction member 16. Their position and their spatial orientation are therefore fixed by construction and cannot be modified. This contributes in particular to the simplicity of the aeraulic design of the hairdressing appliance 1 and to the reliability of the operation of the latter. Arranged so as to be interposed in the flow F of air circulating in the blowing head 5 towards the outside of the hairdressing appliance 1, each of the primary air deflectors 22 of the air direction member 16 advantageously extends in a first average direction from a leading edge to an opposite trailing edge, and from a first lateral end to a second lateral end in a second average direction which is secant to 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 axis CC' of longitudinal extension of the air direction member 16 (but not necessarily parallel to said axis CC' of average longitudinal extension).

Even more advantageously, the primary air deflectors 22 are arranged in a single row. Thus, as seen in the example at figure 13 , each 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 of extension. Preferably, in terms of simplicity of aeraulic design and manufacturing in particular, the primary air deflectors 22 are arranged with their median planes Pm2 arranged parallel to each other.

• au moins une portion centrale qui présente une face concave orientée (généralement) à l'encontre du sens du flux F d'air circulant dans l'organe de direction d'air 16 en provenance de ladite entrée d'air 17, c'est-à-dire donc orientée (généralement) en direction de la deuxième extrémité 21 de la paroi latérale 19 de l'organe de direction d'air 16, et
• au moins de deux portions latérales, agencées de part et d'autre de ladite au moins une portion centrale, et qui présentent chacune une face convexe orientée à l'encontre du sens du flux F d'air circulant dans l'organe de direction d'air 16 en provenance de ladite entrée d'air 17, c'est-à-dire donc orientée (généralement) en direction de la deuxième extrémité 21 de la paroi latérale 19 de l'organe de direction d'air 16.

For reasons similar to those mentioned previously in connection with the first air deflectors 7A, 7B, 7C, it is advantageous to provide, as seen in the example at figure 13 in particular, that the primary air deflectors 22 of such a single row comprise

• at least one central portion which has a concave face oriented (generally) against the direction of the air flow F circulating in the air direction member 16 coming from said air inlet 17, that is to say therefore oriented (generally) in the direction of 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 flow F of air circulating in the air direction member 16 coming from said air inlet 17, that is to say therefore oriented (generally) in the direction of the second end 21 of the lateral wall 19 of the air direction member 16.

In order to further improve the aeraulic performance of the hairdressing appliance 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 is arranged inside the air direction member 16, in said hollow interior shape of the latter. Thus, at least a portion of the leading edges of the primary air deflectors 22 is arranged in of said hollow inner shape, so as to intercept at least part of the air flow F circulating in the air direction member 16 in the direction from the first end 20 to the second end 21 of said side wall 19 of the latter. Even more advantageously, as can be seen in the figure 14 in particular, the leading edges of the primary air deflectors 22 are arranged in a manner progressively offset from one another along the axis CC' of longitudinal extension of the air direction member 16 and in the direction of the second end 21 of the side 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 axis of average extension of said hollow internal shape 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 advantageously contributes to controlling the homogeneity of the air flow F in terms of flow rate, by preventing the air deflector(s) primary air deflector(s) 22 positioned closest to the air inlet 17 do not intercept too large a portion of the air flow F, which could lead to a “blockage” of the flow F and to an insufficient residual air flow rate F at the level of the primary air deflector(s) 22 positioned furthest from the air inlet 17.

Preferably, the hairdressing appliance 1 is designed and configured so that at least a portion of a plurality of said primary air deflectors 22 is arranged aligned with a plurality of said first secondary air deflectors 7A, 7B, 7C, at least when the hairdressing appliance 1 is in an operating mode in which the air flow F is intended to be blown out of the hairdressing appliance 1 via the first air blowing outlet 6. In other words, a plurality of said first secondary air deflectors 7A, 7B, 7C is arranged in the continuity of at least a portion of at least some of the primary air deflectors 22, in consideration of the direction of circulation of the air flow F. This particular technical characteristic, and the associated effects and advantages will be explained in the following.

Advantageously, as in the embodiment illustrated in the figures, the blowing head 5 carries at least one second air blowing outlet 23, that is to say at least one other air blowing outlet, which is distinct from said first air blowing outlet 6, to blow the air flow F out of the hairdressing appliance 1. The blowing head 5 therefore carries a plurality of said air blowing outlets 6, 23, distinct from each other. As in the embodiment illustrated in the figures, the blowing head 5 advantageously has a first face 10 which, as envisaged above, carries said first air blowing outlet 6, and a second face 24 which carries said second air blowing outlet 23. Said first and second faces 10, 24 constitute different, and preferably opposite, faces of the hairdressing appliance 1. Advantageously, the first and second air blowing outlets 6, 23 exist simultaneously (i.e. they are both permanently present on the hairdressing appliance 1), and not alternately. Typically, the hairdressing 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 blowing 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 hairdressing appliance 1.

• une première configuration de direction d'air (ou « première configuration de distribution d'air ») dans laquelle l'organe de direction d'air 16 dirige le flux F d'air initié vers (et de préférence uniquement vers) la première sortie de soufflage d'air 6 (figure 6), selon un premier mode de soufflage (figures 1 à 3, 6, 7, 10 et 21), et
• une deuxième configuration de direction d'air (ou « deuxième configuration de distribution d'air ») dans laquelle l'organe de direction d'air 16 dirige le flux F d'air initié vers (et de préférence uniquement vers) la deuxième sortie de soufflage d'air 23, réciproquement donc selon un deuxième mode de soufflage (figures 5, 8, 9, 12 et 22).

In return, the air direction member 16 and the blowing 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 member 16 directs the initiated air flow F towards (and preferably only towards) the first air blowing outlet 6 ( figure 6 ), according to a first blowing mode ( 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 member 16 directs the initiated air flow F towards (and preferably only towards) the second air blowing outlet 23, reciprocally therefore according to a second blowing mode ( figures 5 , 8 , 9 , 12 And 22 ).

The air direction member 16 is thus advantageously designed and configured to define, or at least to contribute to defining, different paths of the air flow F within the hairdressing appliance 1 according to the air direction configuration that it occupies relative to the blowing head 5. Advantageously, the air direction member 16 is configured to deflect the air flow F leaving the air guide channel 13 described above alternately towards one or the other of the first and second air blowing outlets 6, 23, according to the air direction configuration that it occupies relative to the blowing head 5. Preferably, the air direction member 16 comprises a (single and) unique air direction outlet 18, as mentioned in the above, for directing the air flow F, via said air direction outlet 18, towards the first air blowing 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 vice versa towards the second air blowing outlet 23 when the air direction member 16 is in said second air direction configuration ( figures 5 , 8 , 9 , 12 And 22 ). In said first air direction configuration, the air direction outlet 18 of the air direction member 16 is thus in airflow communication with the first air blowing outlet 6, while in said second air direction configuration, said air direction outlet 18 is reciprocally in airflow communication with the second air blowing outlet 23. Preferably, the air direction member 16 comprises a (single and) single 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 therefore regardless of the blowing mode considered.

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 air flow F entering through the air inlet 17 leaves through the air direction outlet 18 in a mean outlet direction which is intersecting with (or at least arranged in an inclined manner relative to) a mean inlet direction in which the air flow F enters the air direction member 16 through said air inlet 17 ( figures 6 And 8 ), and this therefore regardless of the air direction configuration in which the air direction member 16 is located relative to the blowing head 5.

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 hairdressing appliance 1 in “blowing brush” mode. As such, 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 hairdressing appliance 1 in “hairdryer” mode. As such, the second air blowing outlet 23 has preferably an air blowing opening, preferably a single one. For example, as illustrated in the figures, said air blowing opening is of oblong or oval section, and extends for example longitudinally along said axis BB' of average longitudinal extension of the blowing head 5, to blow the air flow F in the form of an air blade. Alternatively, said air blowing opening could be for example of circular section, to blow the air flow F in a substantially cylindrical or frustoconical shape. Preferably, the second air blowing outlet 23 is defined by a nozzle 25, for example fixed (irremovable) or on the contrary removable (removable), at least a portion of which extends projecting from a surface of said second face 24 of the blowing head 5, typically projecting from the external surface of the housing. Thus, the second air blowing outlet 23 is advantageously easily identifiable by the user.

Regardless of the configuration of the second air blowing outlet 23, the blowing head 5 preferably comprises (second) air deflectors 26 (or " air deflector elements ") for guiding the air flow F out of the hairdressing appliance 1 via said second air blowing outlet 23, when the air directing member 16 therefore occupies said second air directing configuration. As 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 blowing outlet 26 or, as illustrated in the figures, inside the blowing head 5 and upstream of the second air blowing outlet 26. Typically, the second air deflectors 26 form fins, flaps or “blades”, and may each have a substantially planar shape or, as in the embodiment illustrated in the figures, a curved shape. Said second air deflectors 26 are therefore advantageously designed and configured to guide towards the outside of the blowing head 5, via the second air blowing outlet 23, the initiated air flow F which is directed towards the second air blowing outlet 23 coming from the air direction outlet 18 of the air direction member 16.

In the same way that said first air deflectors 7A, 7B, 7C of the blowing head 5 can be described as “secondary first air deflectors 7A, 7B, 7C”, said second air deflectors 26 of the blowing head 5 can be advantageously called “second secondary air deflectors 26” when the air direction outlet 18 of the air direction member 16 comprises primary air deflectors 22 as envisaged in the above. It is understood that said second secondary air deflectors 26 are then distinct from said primary air deflectors 22.

Thus, in operation of the hairdressing appliance 1 according to said second blowing mode (second air direction configuration of the air direction member 16), the air flow F initiated by the blower module 11 is advantageously first guided, straightened, at the outlet of the air direction member 16 by the primary air deflectors 22, before being guided, straightened, by the second secondary air deflectors 26 and thus blown out of the hairdressing appliance 1 in the direction of 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 air flow F.

Preferably, the second air deflectors 26 are fixed. In other words, said second air deflectors 26 are immobile relative to the second air blowing outlet 23 of the blowing head 5. Their position and their spatial orientation are therefore fixed by construction and cannot be modified. This contributes in particular to the simplicity of the aeraulic design of the hairdressing appliance 1 and to the reliability of the operation of the latter. Arranged so as to be interposed in the flow F of air circulating in the blowing head 5 towards the outside of the hairdressing appliance 1, each of the second air deflectors 26 of the blowing head 5 advantageously extends in a first average direction from a leading edge to an opposite trailing edge, and from a first lateral end to a second lateral end in a second average direction which is secant to said first average direction. Advantageously, as illustrated in the example figures, said second air deflectors 26 are arranged in at least one row. Even more advantageously, said 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 a direction of extension of the row(s) of second deflectors. air 26. Such a configuration is particularly well suited to the case where the second blowing mode is a “hair dryer” mode, the air blowing opening of the second air blowing outlet 23 is of oblong, oval or circular section, as envisaged in the above. Advantageously, each of the second air deflectors 26 extends along a respective median plane Pm3 of extension. Preferably in terms of simplicity of aeraulic design and manufacturing in particular, the second air deflectors 26 are arranged with their median planes Pm3 arranged parallel to each other.

Preferably, as already discussed in the above, the hairdressing appliance 1 is designed and configured so that at least a portion of a plurality of said primary air deflectors 22 of the air distribution member 16 is arranged aligned with a plurality of said first secondary air deflectors 7A, 7B, 7C of the blowing head 5 when the air directing member 16 is in said first air directing configuration (first blowing mode).

Preferably, the hairdressing appliance 1 is designed and configured so that at least a portion of a plurality of said primary air deflectors 22 of the air distribution member 16 is arranged aligned with a plurality of said second secondary air deflectors 26 when the air direction member 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.

• au moins une portion d'une pluralité des déflecteurs d'air primaires 22 de la sortie de direction d'air 18 de l'organe de direction d'air 16 est agencée alignée avec une pluralité des premiers déflecteurs d'air 7A, 7B, 7C secondaires lorsque l'organe de direction d'air 16 est dans la première configuration de direction d'air (figures 6, 7 et 19), et
• au moins une portion d'une pluralité des déflecteurs d'air primaires 22 de la sortie de direction d'air 18 de l'organe de direction d'air 16 est respectivement agencée alignée avec une pluralité des deuxièmes déflecteurs d'air 26 secondaires lorsque l'organe de direction d'air 16 est dans la deuxième configuration de direction d'air (figures 8, 9 et 20).

More particularly preferably still, as in the embodiment illustrated in the figures, said hairdressing appliance 1 is designed and configured so 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 second secondary air deflectors 26 when the air direction member 16 is in the second air direction configuration ( figures 8 , 9 And 20 ).

In other words, in said 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 first secondary air deflectors 7A, 7B, 7C. Conversely, in said 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 second secondary air deflectors 26.

A plurality of said first secondary air deflectors 7A, 7B, 7C is thus advantageously arranged in the continuity of at least a portion of at least some of said primary air deflectors 22, in consideration of the direction of circulation of the air flow 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 second secondary air deflectors 26 is thus advantageously arranged in the continuity of at least a portion of at least some of said primary air deflectors 22, in consideration of the direction of circulation of the air flow F. Advantageously, when said at least portion of primary air deflectors 22 is arranged aligned with said plurality of second secondary 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 second secondary air deflectors 26 concerned ( figures 8 , 9 And 20 ).

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

Thanks to each of the aforementioned characteristics, and even more so thanks to the combination of said characteristics, the hairdressing appliance 1 advantageously forms a multi-mode blowing appliance (or "multifunction") of particularly simple and efficient aeraulic 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, to homogenize, in a particularly efficient manner the blowing of the air flow F out of the hairdressing appliance 1 in the direction of the hair, depending on the (first or second) air blowing outlet 6, 23 used. It is thus in particular possible, as in the embodiment illustrated in the figures, to obtain a hairdressing appliance 1 of ergonomic use, offering at least first and second different blowing modes in which the air flow F can be blown out of the hairdressing appliance 1 towards the hair in a simple and effective manner respectively according to first and second air blowing directions which are inclined relative to, and in particular orthogonal to, the axis A-A' of longitudinal extension of the handle 2 of the hairdressing appliance 1. In addition, the simplicity of the aeraulic design of the hairdressing appliance 1 advantageously makes it easier to manufacture the latter, and further contributes to the robustness and reliability of the latter.

Advantageously in terms of simplicity of design, as illustrated by example in the figures, the blowing head 5 is preferably devoid of:

• additional air deflectors (shutters or “blades”) which 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
• additional air deflectors (shutters or “blades”) which would be arranged between the first secondary air deflectors 7A, 7B, 7C and the first air blowing outlet 6, respectively between the second secondary air deflectors 26 and the second air blowing outlet 23.

For example, as in the embodiment illustrated in the figures, the blowing head 5 comprises three rows RA, RB, RC of first air deflectors 7A, 7B, 7C each comprising three first air deflectors 7A, 7B, 7C. Advantageously, the blowing 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. Particularly advantageously, in said first air direction configuration of the air direction member 16 (or at least when the hairdressing appliance 1 is intended to blow said air flow F via said first air blowing 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 air deflectors 7A, 7B, 7C (secondary) of at least one of the three rows RA, RB, RC of first deflectors secondary air 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 second secondary air deflectors 26 ( figure 20 ).

In order to mechanically reinforce the primary air deflectors 22, the air direction member 16 preferably comprises spacers 27 (“primary spacers”), which mechanically connect said primary air deflectors 22 to each other two by two 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. between them, 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 which could be caused by the presence of said primary spacers 27.

As already mentioned previously, in order to mechanically reinforce the first air deflectors 7A, 7B, 7C, the blowing head 5 may advantageously comprise first spacers 8 (or “first secondary spacers” where appropriate), which mechanically connect said first air deflectors 7A, 7B, 7C to each other two by two. 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 blowing head 5 may advantageously comprise second spacers (or “second secondary spacers” where appropriate), which mechanically connect said second air deflectors 26 to each other. Preferably, said second spacers are then arranged aligned along at least one line of spacers, and possibly along two lines of second spacers.

Even more preferably, the or each of the line(s) 27A, 27B of primary spacers 27 is arranged aligned, coplanar, in an alignment plane Pa1 with the or one of the line(s) 8A, 8B of first corresponding secondary spacers 8, in said first air direction configuration of the air direction member 16 or at least when the hairdressing appliance 1 is intended to blow the air flow F via the first air blowing outlet 6 ( figure 21 ). Conversely, the or each of the line(s) 27A, 27B of primary spacers 27 may advantageously be arranged aligned, coplanar, in an alignment plane with the or one of the line(s) of corresponding second secondary 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 caused by the presence of said spacers. In general, the implementation of such first (secondary) spacers 8, primary spacers 27 and second (secondary) spacers advantageously allows dimensioning the first air blowing outlet 6, the air direction outlet 18 of the air direction member 16 and/or the second air blowing outlet 23 so 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 the second air deflectors 26 (secondary).

In order to ensure optimal blowing of the air flow F towards the hair, in particular in terms of air flow rate, the first air blowing outlet 6 has a minimum total useful section (i.e. sum of the useful sections of each of the portions of the first air blowing outlet 6) which is preferably between 1 cm ² and 20 cm ² , and even more preferably between 8 cm ² and 15 cm ² . For the same reasons, the second air blowing outlet 23 has a minimum total useful section which is preferably between 1 cm ² and 20 cm ² , and even more preferably between 8 cm ² and 15 cm ² . Even more preferably, the first air blowing outlet 6 and the second air blowing outlet 23 have minimum total useful sections of identical values. In return, the air inlet 17 of the air direction member 16 preferably has a useful section (or “useful air inlet section”) of between 1 cm ² and 20 cm ² , and more preferably still between 8 cm ² and 15 cm ² . As for it, the air direction outlet 18 of the air direction member 16 has a useful section (or “useful air outlet section”) which is preferably between 1 cm ² and 20 cm ² , and more preferably still between 8 cm ² and 15 cm ² .

• une première portion de canalisation 28 prévue pour assurer une mise en communication aéraulique de la sortie de direction d'air 18 de l'organe de direction d'air 16 avec la première sortie de soufflage d'air 6 de la tête de soufflage 5 lorsque l'organe de direction d'air 16 occupe la première configuration de direction d'air, et
• une deuxième portion de canalisation 29 prévue pour assurer une mise en communication aéraulique de ladite sortie de direction d'air 18 avec la deuxième sortie de soufflage d'air 23 lorsque l'organe de direction d'air 16 occupe la deuxième configuration de direction d'air.

The blowing head 5 advantageously comprises, as in the embodiment illustrated in the figures,

• a first portion of pipe 28 provided to ensure air communication between the air direction outlet 18 of the air direction member 16 and the first air blowing outlet 6 of the blowing head 5 when the air direction member 16 occupies the first air direction configuration, and
• a second portion of pipe 29 provided to ensure air communication between said air direction outlet 18 and the second air blowing outlet 23 when the air directing member 16 occupies the second air directing configuration.

As illustrated in the figures, the blowing head 5 may comprise for this purpose an internal ducting device 30, which at least partly defines said first and second ducting portions 28, 29, and which therefore constitutes a “two-way” internal ducting device (or “two-way distributor”). Said internal ducting device 30 is advantageously fixed, immobile, relative to the first and second air blowing outlets 6, 23 of the blowing head 5. The air directing member 16 and the internal ducting device 30 of the blowing head 5 are therefore mounted to be movable relative to each other between said first and second air directing configurations. Thus, when the air directing member 16 occupies the first air directing configuration ( figures 1 to 3 , 6 , 7 , 10 And 21 ), the air direction outlet 18 of the air direction member 16 is in air communication with the first duct portion 28 of the internal duct device 30, and therefore with the first air blowing outlet 6. On the other hand, the air direction member 16 (for example, the side wall 19 of the latter) then closes the second duct portion 29 of the internal duct 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 air communication with the second duct portion 29, and therefore with the second air blowing outlet 23. The air direction member 16 (for example, the side wall 19 of the latter) then closes the first duct portion 28 of the internal duct device 30.

Preferably, the air direction member 16 is arranged at least partly in the internal channeling device 30, which contributes to reducing the size of the blowing head 5, and more generally the size of the hairdressing appliance 1. Advantageously, the first air deflectors 7A, 7B, 7C (secondary) and/or the second air deflectors 26 (secondary) that the blowing head 5 comprises are carried by said internal channeling device 30 ( figures 15 to 20 ). Advantageously, as in the embodiment illustrated in the figures, the first portion of duct 28 has a useful air passage section which decreases continuously in the direction of the first air blowing outlet 6. Conversely, the second portion of duct 29 advantageously has a useful air passage section which decreases continuously in the direction of the second air blowing outlet 23. This advantageously contributes to facilitating the circulation of the air flow F in the direction of the first air blowing outlet 6 ( figure 21 ), respectively towards the second air blow outlet 23 ( figure 22 ), and thus to reduce the risk of air blockage and increase in air pressure inside the blowing head 5, as well as the risk of air (possibly hot) leaking into other parts of the blowing head 5.

Different kinematics of the air direction member 16 and the blowing head 5 can be envisaged, depending in particular on the conformation and configuration of the air direction member 16. Preferably, however, in terms of simplicity of design and use of the hairdressing appliance 1, the blowing head 5 is connected immobile to the handle 2 of the hairdressing appliance 1, and the air direction member 16 is mounted movable relative to the blowing head 5 and to the handle 2 between said first and second air direction configurations. In order in particular to simplify the design of the hairdressing appliance 1 and to improve its compactness, the air direction member 16 and the blowing head 5 are preferably mounted movable in rotation, in pivoting, along an axis DD' of rotation, relative to each other between at least said first and second air direction configurations. Preferably, said axis DD' of rotation is coincident with (collinear to), or at least parallel to, the axis CC' of longitudinal extension of the air direction member 16, which is itself advantageously coincident with (collinear to) the axis BB' of average longitudinal extension of the blowing head 5. According to a variant (not illustrated), the air direction member 16 is connected immobile relative to the handle 2, and the blowing head 5 is then mounted to be able to rotate, along said axis DD' of rotation, relative to the air direction member 16 and to the handle 2. According to another variant, implemented in the embodiment illustrated in the figures, the blowing head 5 is connected immobile to the handle 2, and the air direction member 16 is mounted to be able to rotate, along said axis DD' of rotation, relative to the blowing head 5 and to the handle 2. In accordance with what above, this second variant proves preferable insofar as it contributes to making the hairdressing appliance 1 simpler to design and use. In this case, the internal channeling device 30 mentioned above is thus itself advantageously connected immobile to the handle 2 of the hairdressing appliance 1, the organ of air direction 16 being advantageously arranged to be movable in rotation, along said axis DD' of rotation, in said internal channeling device 30 between said first and second air direction configurations.

In order to further improve the practical and intuitive nature of the hairdressing appliance 1 to use, said first and second air blowing outlets 6, 23 are preferably arranged opposite each other, on either side of a plane P1 in which a mean extension direction of the hairdressing appliance 1 (or where appropriate one of the mean extension directions of the hairdressing appliance 1) is inscribed. Said average extension direction therefore advantageously corresponds here to an average extension direction of a portion of the hairdressing appliance 1 which carries said first and second air blowing outlets 6, 23. Said average extension direction of the hairdressing appliance 1 thus preferably corresponds to the axis B-B' of average longitudinal extension of the blowing head 5. Said first and second air blowing outlets 6, 23 are therefore thus preferentially arranged in an opposite manner relative to each other, on either side of a plane P1 in which said axis B-B' of average longitudinal extension is inscribed. In this way, the first and second air blowing outlets 6, 23 are thus advantageously not simultaneously visible to the user, when the latter looks straight on at the first air blowing outlet 6, and respectively at the second air blowing outlet 23. The user can easily use the hairdressing appliance 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 hairdressing appliance 1 to orient the corresponding one of said first and second air blowing outlets 6, 23 opposite the hair to be treated, in the preferred case where the blowing head 5 is stationarily connected to the handle 2 and where the air direction member 16 is mounted to be able to rotate relative to the blowing head 5 and to the handle 2.

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

Advantageously, the hairdressing appliance 1 also comprises a control system 31, for controlling each passage of the hairdressing appliance 1 from one to the other of the first and second air direction configurations. The control system 31 is therefore provided to allow the user to alternately select one or the other of the blowing modes, that is to say to control the passage of the hairdressing appliance 1 from one of the blowing modes to another of the blowing modes, and for example from the first blowing mode to the second blowing mode and vice versa from the second blowing mode to the first blowing mode. In this respect, as in the embodiment illustrated in the figures, the control system 31 is advantageously connected to the air direction member 16 to control each passage of the air direction member 16 from one to the other of said first and second aforementioned air direction configurations. By acting on the control system, the user can thus alternately select one or other of the blowing modes of the hairdressing appliance 1 from among said at least two different blowing modes. The user can thus advantageously choose through which of the first and second air blowing outlets 6, 23 the air flow F will be blown out of the hairdressing appliance 1, and thus choose the operating mode of the hairdressing appliance 1. The control system 31 is advantageously distinct from the manual control and/or adjustment means 15 of the electrical operation of the hairdressing appliance 1 and the cold air/air switch hot, as described above, that the hairdressing appliance 1 may optionally comprise. It is thus advantageously possible for the user to select one of the blowing modes, while another of the blowing modes is selected, prior to starting the blowing module 11 of the hairdressing appliance 1. The control system 31 is advantageously carried by the blowing head 5, and is preferably positioned along the axis BB' of average longitudinal extension 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 blowing head 5. This allows easy and intuitive activation of the control system by the user.

Advantageously, the control system 31 for changing the blowing mode of the hairdressing appliance 1 comprises a manual control member which is movable, for example a button 32 or a wheel, to allow the user to act on said control system, and thus manually select alternately one or the other of said blowing modes. By "mobile", it is advantageously meant here that the manual control member is able to move between at least two advantageously predefined positions and/or spatial orientations (relative to the rest of the hairdressing appliance 1), typically by translation, rotation and/or even by tilting under the effect of a manual mechanical action exerted against it by the user. Preferably, as illustrated in the example figures, said manual control member is arranged at the level of the blowing head 5, that is to say that it is carried by (or that it belongs to) the blowing head 5, and not at the level of the handle 2. This makes it possible to limit a risk of involuntary manipulation of the manual control member by the hand of the user who is holding the handle 2. More preferably, the manual control member is arranged at such a distance from the handle 2 that it cannot be reached by a finger of the hand of the user who is holding the handle 2. Inaccessible to a finger of the hand of the user who is holding the handle 2, the manual control member remains, however, advantageously accessible to a finger of the other hand of the user. Even more preferably, still as illustrated in the example figures, said manual control member is arranged substantially along an axis parallel to, or coincident with, the axis BB' of average longitudinal extension of the blowing head 5, so that it is therefore accessible to the user from above the blowing head 5.

Advantageously, as illustrated in the figures, the control system 31 of the hairdressing appliance 1 is a push-push button control mechanism 32 (or “push-push kinematic control mechanism”, or “ push-push ” button control mechanism), to thus control each transition of the hairdressing appliance 1 from one of the blowing modes to another of the blowing modes. Intended to be actuated by the user, for example manually, the control system 31 is therefore designed and configured to transform each push exerted by the user (typically using a finger of the user) on the button 32 of the control system 31 into a transition of the hairdressing appliance 1 from one of the blowing modes to another of the blowing modes or, at the very least, from one of the blowing modes to another of the blowing modes. The button 32 of the control system 31 then advantageously forms said manual control member mentioned above. As in the embodiment illustrated in the figures, the push-push button control mechanism 32 is thus advantageously connected to the air direction member 16 to control each passage of the air direction member 16 from one to the other of the first and second air direction configurations.

Thanks to such a push-push button 32 control mechanism, the use of the hairdressing appliance 1 is thus particularly simple and intuitive, since the reproduction of a simple pushing action carried out by the user against the button 32 of the control mechanism, each time in the same pushing direction, controls each change of blowing mode of the hairdressing appliance 1. Each push exerted by the user on the button 32 of the control mechanism thus controls a cyclical passage of the hairdressing appliance 1 from a given initial blowing mode to a following blowing mode, and so on, until returning to said initial blowing mode after the control mechanism has been successively actuated as many times as the hairdressing appliance 1 has different blowing modes. Advantageously, said push-push button 32 control system/mechanism conforms, at least in its operating principle, to that described in the documents WO-2022/263775 A1 , WO-2022/263774 A1 , WO-2023/118682 A1 And WO-2023/118683 A1 on behalf of SEB SA, the content of which is therefore advantageously incorporated here by reference.

It should be noted that the terms "first" , "second" and "third " used in the foregoing are not intended, as such, to introduce any technical limitation, but only to facilitate the understanding of the invention. As such, these terms may be omitted where there is no possible confusion.
