Description

Title of the invention: Multi-mode blowing hairdressing appliance with blowing head equipped with internal airtight walls

[0001] The present invention relates to the general technical field of hairdressing appliances, for example for domestic use, and more precisely to the field of portable 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 hairdressing appliances, appliances are already known that are designed to blow a flow of air towards the hair using different blowing modes, in order to give these appliances a multifunctional character, for carrying out various hair drying and / or styling techniques using a single appliance. For example, hand-held hair dryers are known, comprising a handle and a blowing head, which has an air 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 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 a plurality of 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 the user to assemble / disassemble the accessories, or to manipulate an accessory pre-assembled at the air outlet. Such an operation can sometimes prove tedious, which is detrimental to 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.

[0003] To address these issues, a new portable hairdressing appliance has recently been proposed comprising a hand-held grip handle and a blowing head connected to the handle, the blowing head carrying first and second air blowing outlets, for blowing a flow of air out of the appliance, typically according to first and second different blowing modes. The appliance in question further comprises a blowing module for initiating said air flow, as well as a air directing member arranged within the blowing head, the blowing head and the air directing member being mounted to be movable relative to each other between a first air directing configuration in which the air directing member directs the initiated air flow towards the first air blowing outlet, and a second air directing configuration in which the air directing member directs the initiated air flow towards the second air blowing outlet.

[0004] While such a hairdressing appliance has a number of advantages with regard to the aforementioned problems, it has been observed that such a known appliance still has room for improvement, in particular in terms of the efficiency of its aeraulic design, the latter having a significant impact on the performance of the appliance and on the quality of the result of the hairdressing operations carried out using the appliance, as well as in terms of the safety of use of the appliance.

[0005] The objects assigned to the invention therefore aim to propose a new multifunctional portable hairdressing appliance which is of particularly efficient aeraulic design, while being particularly practical to use.

[0006] The objects assigned to the invention therefore aim to propose a new multifunctional portable hairdressing appliance whose use is particularly safe.

[0007] Another object of the invention is to propose a new portable hairdressing appliance of particularly simple and compact construction.

[0008] Another object of the invention is to propose a new portable hairdressing appliance which is particularly robust and reliable.

[0009] Another object of the invention is to propose a new portable hairdressing appliance allowing a user to easily and efficiently carry out a plurality of separate operations, without requiring the use of an external complementary hairdressing appliance.

[0010] Another object of the invention is to propose a new multifunctional portable hairdressing appliance which is particularly ergonomic, easy and safe to use, in particular for a user without particular professional hairdressing skills.

[0011] The objects assigned to the invention are achieved using a portable hairdressing appliance comprising - a hand grip handle and a blowing head connected to the handle, the blowing head comprising a housing and carrying first and second air blowing outlets for blowing an air flow out of the hairdressing appliance, - a blower module for producing said air flow, an air direction member comprising an air inlet in aeraulic connection with the blower module and through which the air flow enters the air direction member in a mean inlet direction, the air direction member being mounted to move at the interior of the blower head housing at least between a first air direction configuration in which the air direction member directs the air flow towards the first air blow outlet, and a second air direction configuration in which the air direction member directs the air flow towards the second air blow outlet, - a control system, which is mechanically connected to the air direction member to control each passage of the air direction member from one to the other of said first and second air direction configurations, the blowing head extending along a mean extension axis between a lower end at which the blowing head is connected to the handle and a free upper end, the housing of the blowing head comprising a first portion, which extends along said mean extension axis from said lower end towards said free upper end and in which the air direction member is arranged, and a second portion which extends said first portion along said mean extension axis and defines said free upper end, and in which the control system is arranged, the housing of the blowing head comprising an internal face which carries at least a first peripheral wall, the control system comprising a portion which is arranged stationary relative to said housing and at a distance from said free upper end of the blowing head, and which carries at least a second peripheral wall,said first peripheral wall being arranged in contact with said second peripheral wall and overlapping the surface thereof to oppose the passage of air from said air flow from the first portion through said second portion in a mean direction parallel to said mean direction of entry of the air flow.

[0032] The hairdressing appliance 1 according to the invention, a non-limiting embodiment of which is illustrated as an example in the figures, is a portable hairdressing appliance, designed to be grasped and handled by hand. It is a hairdressing appliance 1 preferably intended for use in a domestic setting by a user (male or female) lacking any 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 themselves, that is to say on their 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.

[0033] The hairdressing appliance 1 comprises means for generating an air flow F which, as will be understood from reading what follows, are designed and configured to generate said air flow F according to at least two different blowing modes, namely at least a first blowing mode and a second blowing mode, which is therefore different from said first blowing mode. It is therefore an advantageously “multimode” or “multifunction” appliance, being designed and configured to blow an air flow F towards hair according to at least two different blowing modes, which can be alternately selected by the user.By "different blowing modes" is preferably meant blowing modes according to which the hairdressing appliance 1 blows an air flow which differs, for example in its shape, its direction and / or its intensity, in order to allow different operations to be carried out on the hair, depending on the blowing mode chosen, such as for example carrying out a hair drying operation or a hair shaping operation.

[0034] The hairdressing appliance 1 comprises at least a first air blowing outlet 2 for blowing the air flow F out of the hairdressing appliance 1, for example in a first of said blowing modes and a second air blowing outlet 3 for blowing the air flow F out of the hairdressing appliance 1, for example in a second of said blowing modes. Said first and second air blowing outlets 2, 3 are advantageously distinct from each other, preferably distant from each other, preferably opposite each other. As in the embodiment lisation illustrated in the figures, the hairdressing appliance 1 advantageously has a first face 4, which carries the first air blowing outlet 2 and a second face 5 which carries the second air blowing outlet 3. The first and second faces 4, 5 constitute different, and preferably opposite, faces of the hairdressing appliance 1. Advantageously, the first and second air blowing outlets 2, 3 exist simultaneously (that is to say they are both permanently present on the hairdressing appliance 1), and not alternately. Typically, the hairdressing appliance 1 comprises a housing 6, for example made of plastic, an external face of which defines at least a part of the first and second faces 4, 5 of the hairdressing appliance 1. Said housing 6 has an external surface (defined by said external face) which defines at least a portion of an external surface of the hairdressing appliance 1.

[0035] Preferably, said blowing modes correspond to different paths of the air flow F within the hairdressing appliance 1. The hairdressing appliance 1 is therefore preferably designed and configured so that the air flow F takes different (aeraulic) paths inside the hairdressing appliance 1 depending on the blowing mode selected by the user. Thus, the air flow F therefore advantageously follows at least a first path within the hairdressing appliance 1 in the first blowing mode, until it is blown out of the hairdressing appliance 1 via the first air blowing outlet 2 ([Fig. 6]). In the second blowing mode, the air flow F advantageously follows another path within the hairdressing appliance 1, i.e.a path which differs at least in part from the path(s) taken by the air flow F in the first blowing mode, until it is blown out of the hairdressing appliance 1 via the second air blowing outlet 3 ([Fig.7]). The implementation of such different air paths advantageously allows the definition of very different blowing modes, depending in particular on the chosen configuration and conformation of the first and second air blowing outlets 2, 3, the relative arrangement of the latter, etc. In particular, this makes it possible to provide blowing modes according to which the air flow F is blown out of the hairdressing appliance 1 in respective different directions, possibly opposite, and for example via air blowing outlets 2, 3 distant from each other.

[0036] As in the embodiment illustrated in the figures, the first blowing mode can advantageously correspond to an operating mode of the hairdressing appliance 1 in “blowing brush” mode (figures 3, 6, 7 and 9 in particular), while the second blowing mode can advantageously correspond to an operating mode of the hairdressing appliance 1 in “hairdryer” mode (figures 5, 8 and 12 in particular). Obviously, the invention is not limited to such particular blowing modes, and other blowing modes may be envisaged in depending on the uses for which the hairdressing appliance 1 is intended in terms of drying and / or shaping hair. Furthermore, the number of different blowing modes is not, in practice, limited to two. Furthermore, a given blowing mode may possibly correspond to a plurality of different paths of the air flow F inside the hairdressing appliance 1.

[0037] The hairdressing appliance 1 comprises a handle 7 (or grip) for manual gripping, which is intended to be grasped manually by the user to manipulate the hairdressing appliance 1. Advantageously defined by a portion of the housing 6 of the hairdressing appliance 1, the handle 7 typically extends between a first end 8 and a second opposite end 9, preferably longitudinally along an axis A-A' of average extension. The handle 7 advantageously has a slender, elongate shape, so that it can be grasped with the full hand by an adult user. The hairdressing appliance 1 further comprises a blowing head 10, for blowing the air flow F out of the hairdressing appliance 1, towards the hair.Connected to the handle 7, the blowing head 10 carries said first and second air blowing outlets 2, 3, so that the air flow F is therefore advantageously intended to be blown out of the hairdressing appliance 1 towards the hair via the blowing head 10. Said blowing head 10 preferably has at least a first face, which defines or at least contributes to advantageously defining said first face 4 of the hairdressing appliance 1, and which carries the first air blowing outlet 2. Said blowing head 10 preferably also has a second face, which defines or at least contributes to advantageously defining said second face 5 of the hairdressing appliance 1, and which carries the second air blowing outlet 3.

[0038] As such, the blowing head 10 comprises a housing 6A, which advantageously constitutes a part of the housing 6 of the hairdressing appliance 1, so that said housing 6 advantageously comprises a part defining the handle 7 and another part which forms, which defines, the housing 6A of the blowing head 10. Typically, said housing 6A can be formed of one or more cover pieces, assembled together, and defines an internal space, in which internal components of the blowing head 10 of the hairdressing appliance 1 are housed, in particular such as the latter will be described in the following. The blowing head 10 extends along an axis B-B' of average extension, between a lower end (first end) at which the blowing head 10 is connected to the handle 7, and thus preferably extends the handle 7 beyond the first end 8 of the latter, and an opposite free upper end (second end).Depending on the conformation and dimensioning of the blowing head 10, said axis B-B' of average extension can constitute a longitudinal extension axis of the head. blowing 10. As in the embodiment illustrated in the figures, the axis B-B' of average extension of the blowing head 10 is advantageously parallel or collinear (merged) with said axis A-A' of average longitudinal extension of the handle 7. The hairdressing appliance 1 then advantageously extends, in general, in a direction of average extension, which is parallel or collinear with said axis A-A' of average longitudinal extension of the handle 7 and with said axis B-B' of average extension of the blowing head 10.

[0039] As in the embodiment illustrated in the figures, the first blowing mode advantageously corresponding to an operating mode of the hairdressing appliance 1 in “blowing brush” mode, the blowing head 10 typically comprises a mechanical hair engagement element 11, capable of mechanically interacting with the user’s hair in particular to brush it, style it and / or comb it. Advantageously carried by the first face of the blowing head 10 (which defines, or contributes to defining, said first face 4 of the hairdressing appliance 1) which also carries the first air blowing outlet 2, the mechanical hair engagement element 11 may comprise a plurality of rows or bars of bristles and / or brush pins.Preferably, as in the embodiment illustrated in the figures, the first air blowing outlet 2 comprises a plurality of air blowing orifices, that is to say therefore a plurality of air blowing outlet portions, which blowing orifices are arranged between pins or brush bristles that comprise the mechanical hair engagement element 11. For example, said air blowing orifices may each be formed by a slot (straight or curved). Thus, the air flow F can be blown optimally towards the hair when the latter is engaged with the mechanical hair engagement element 11 during a hairstyling operation. Preferably, said first air blowing outlet 2 extends longitudinally along the axis B-B' of average extension of the blowing head 10.For example, said first air blowing outlet 2 may then comprise a plurality of air blowing orifices, each in the form of a slot, arranged in a staggered manner along the axis B-B' of average extension of the blowing head 10 ([Fig. 3]). Respectively, the second blowing mode advantageously corresponding to an operating mode of the hairdressing appliance 1 in “hairdryer” mode, the second air blowing outlet 3 preferably has an air blowing opening, preferably a single one, which extends longitudinally along said axis BB' of average extension of the blowing head 10. The second air blowing outlet 3 therefore has an opening of generally oblong shape, elongated, as illustrated as an example in the figures, to blow the air flow F in the form of an air blade. Alternatively, the second air blowing outlet 3. could have, for example, an opening of generally circular shape for blowing the air flow F in a substantially cylindrical or truncated cone shape. Preferably, the second air blowing outlet 3 is defined by a nozzle 12, 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 of the blowing head 10, typically projecting from the external surface of a housing 6A of the blowing head 10. Thus, the second air blowing outlet 3 is advantageously easily identifiable by the user.

[0040] The hairdressing appliance 1 comprises a blower module 13 (or “motor-fan unit”), typically included in the aforementioned means for generating the air flow F, to produce the air flow F, i.e. to initiate said air flow F, from ambient air in the environment of the hairdressing appliance 1. Preferably, the blower module 13 is embedded within the hairdressing appliance 1 itself. The hairdressing appliance 1 is advantageously provided with an air inlet 14, through which ambient air can be sucked in by the blower module 13 in order to be blown towards the hair. The blower module 13, which typically comprises at least one fan driven by an electric motor, can advantageously be arranged within the blower head 10 or within the handle 7, or even be assembled to the handle 7 at the second end 9 of the latter.More preferably, however, the blower module 13 is assembled to the handle 7 at said second end 9 of the latter, so that the blower module 13 advantageously extends the handle 7 beyond the second end 9 of the latter. Advantageously, the blower head 10 is connected to the handle 7 at the first end 8 of the latter. In the case where the blower module 13 is thus arranged within the handle 7 or, more preferably, is assembled to the handle 7 at the second end 9 of the latter, the hairdressing appliance 1 advantageously comprises a guide channel 15 (or (“guide pipe”) arranged at least partly inside the handle 7 to guide, channel, the air flow F initiated by the blower module 13 to the blower head 10.As in the embodiment illustrated in the figures, the guide channel 15 may advantageously be unique, so that it defines a common portion of the different paths taken by the air flow F within the hairdressing appliance 1 according to the different blowing modes. Alternatively, however, several separate guide channels could be implemented, to the detriment, however, of the simplicity of design and manufacture of the hairdressing appliance 1. Advantageously, the means for generating the air flow F according to at least two different blowing modes thus comprise said guide channel 15.

[0041] The blowing head 10 may be designed to be connected, assembled, in a manner removable to the handle 7, so that the user can separate the blowing head 10 from the handle 7, for example to clean or replace the blowing head 10. Alternatively, as in the embodiment illustrated in the figures, the blowing head 10 is designed to remain permanently connected to the handle 7, and is therefore not intended (in normal use) to be dissociated from the handle 7 by the user. This simplifies both the design and the use of the hairdressing appliance 1.

[0042] Preferably, the hairdressing appliance 1 also comprises a heating element provided to raise the temperature of the air flow F produced by the blower module 13. 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 13. As in the embodiment illustrated in the figures, the heating element is advantageously positioned inside the guide channel 15 arranged in the handle 7. The heating element is typically an electric heating element, comprising an electrical heating resistor formed of an electrically conductive wire (not illustrated) wound around an insulating core 16. Alternatively, the heating element could be housed in the blower head 10, to the detriment however of the compactness of the latter.Advantageously, the hairdressing appliance 1 comprises means 17 for manual control and / or adjustment, by the user, of the electrical operation of the hairdressing appliance 1, and in particular of the blower module 13 and / or the heating element. These are adjustment means, for example of the rocker switch type, push button type and / or of the slide or thumbwheel type dimmers as 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 13, 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.Such manual control / adjustment means 17 may be positioned, for example, at the handle 7 or at the blower module 13, when the latter is assembled at the second end 9 of the handle 7 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 7, preferably at its first end 8, to control switching on and / or off of the heating element. Advantageously constituting a portable electric appliance, the hairdressing appliance 1 is preferably designed to be electrically powered from the mains, via a power cord provided at a free end with an electrical connection plug (not illustrated).

[0043] The hairdressing appliance 1 comprises an air directing member 18 (“air distribution member”, or “air deflection member”), for directing, distributing, the flow F of air produced by the blower module 13 towards one and / or the other (and preferably from one or the other) of the first and second air blowing outlets 2, 3 of the hairdressing appliance 1, therefore depending on the blowing mode selected. The air direction member 18 is typically included in the means for generating the air flow F mentioned previously. In this respect, the air direction member 18 is mounted to move inside the housing 6A of the blowing head 10 at least between - a first air direction configuration (or "first air distribution configuration") in which the air direction member 18 directs the air flow F towards (and preferably only towards) the first air blowing outlet 2, for example according to the first blowing mode (figures 3, 6, 7 and 9 in particular), and - a second air direction configuration (or "second air distribution configuration") in which the air direction member 18 directs the air flow F towards (and preferably only towards) the second air blowing outlet 3, for example reciprocally according to the second blowing mode (figures 5, 8 and 12 in particular).

[0044] Arranged in the blowing head 10, the air direction member 18 is therefore 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 10. Advantageously, the air direction member 18 is configured to deflect the air flow F leaving the guide channel 15, mentioned above, alternately towards one or the other of the first and second blowing outlets 2, 3, according to the air direction configuration that it occupies relative to the blowing head 10. Preferably, the air direction member 18 forms an air direction duct (or “air deflection duct”, or “spool”) which extends beyond one end of the handle 7, and typically beyond the first end 8 of the handle 7. .

[0045] The air direction member 18 comprises an air inlet 19, which is in aeraulic connection (i.e. in communication) with the blower module 13, to collect the air flow F produced by the latter, and via which the air flow F enters the air direction member 18 in a mean inlet direction. The air direction member 18 advantageously comprises at least one air direction outlet 20, via which the air flow F is directed by the air direction member 18 towards one and / or the other (and preferably towards one or the other) of the first and second air blowing outlets 2, 3 depending on the air direction configuration occupied by the air direction member 18 with respect to the blowing head 10. Preferably, the air direction member 18 comprises a (single and) single air direction outlet 20, for directing the air flow F, via the air direction outlet 19, towards the first air blowing outlet 2 when the air direction member 18 is in the first air direction configuration (Figures 3, 6, 7 and 9 in particular) and vice versa towards the second air blowing outlet 3 when the air direction member 18 is in the second air direction configuration (figures 5, 8 and 12 in particular). In the first air direction configuration, the air direction outlet 20 of the air direction member 18 is thus in air communication with the first air blowing outlet 2, while in the second air direction configuration, the air direction outlet 20 of the air direction member 18 is reciprocally in air communication with the second air blowing outlet 3. The design of the hairdressing appliance 1 is thus simplified.As in the embodiment illustrated in the figures, said air direction outlet 20, or each of the air direction outlets where appropriate, is advantageously designed and configured so that the air flow F exits the air direction member 18 via the air direction outlet 20 in a mean exit direction which is secant (or at least inclined relative to), and for example substantially orthogonal, to said mean air inlet direction (figures 6 and 8).

[0046] The hairdressing appliance 1 also comprises a control system, 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 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 is mechanically connected to the air direction member 18 to control each passage of the air direction member 18 from one to the other of the aforementioned first and second 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 2, 3 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 is advantageously distinct from the manual control and / or adjustment means 17 of the electrical operation of the hairdressing appliance 1 and the cold air / hot air switch that the hairdressing appliance 1 may optionally comprise. In particular, 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 switching on. of the blower module 13 of the hairdressing appliance 1. As will be understood from reading the following, the control system is advantageously embedded in the blower head 10, and is preferably positioned along the axis B-B' of average extension of the latter. Preferably, at least a portion of an element of the control system forms, or at least contributes to forming, the upper (free) end of the blower head 10. This allows easy and intuitive activation of the control system by the user.

[0047] More specifically, the housing 6A of the blowing head 10 (and more generally the blowing head 10 itself) comprises a first portion 10A, which extends along the axis B-B' of average extension of the blowing head 10 from the lower end of the blowing head 10 towards the free upper end of the blowing head 10. The air direction member 18 is arranged in the first portion 10A of the housing 6A of the blowing head 10, so that said first portion 10A thus advantageously forms a portion called the "aeraulic portion" of the blowing head 10. The housing 6A of the blowing head 10 (and more generally the blowing head 10 itself) also comprises a second portion 10B, which extends said first portion 10A along the axis B-B' of average extension of the blowing head 10 and defines said free upper end of the latter.Respectively, the control system is (at least in part) arranged in the second portion 10B of the housing 6A of the blowing head 10, so that said second portion 10B thus advantageously forms a portion called the “control portion” of the blowing head 10.

[0048] The housing 6A of the blowing head 10 comprises an internal face 21, which is therefore oriented towards the inside of the housing 6A and which is opposite an external face which advantageously defines at least a portion of an external surface of the blowing head 10, and which carries at least a first peripheral wall 22. By “peripheral”, it is here advantageously meant that the first peripheral wall 22 (as well as the third, fifth, sixth and seventh peripheral walls 38, 48, 50, 51A, 51B which will be mentioned later) is carried by the internal face 21 of the housing 6A of the blowing head 10 following at least a part (and preferably the whole) of an internal contour of the housing 6A, that is to say at least a part (and preferably the whole) of a perimeter (or contour) of a section of the blowing head 10 which extends in a plane average secant to the axis B-B' of average extension of the blowing head 10.Preferably, the first peripheral wall 22 has an annular shape. Respectively, the control system comprises a portion 23 which is arranged immobile (or “immobile portion” 23) relative to the housing 6A of the blowing head 10 and at a distance from the free upper end of the blowing head 10. Said immobile portion 23 is therefore distinct from said housing 6A. Arranged inside the housing 6A of . the blowing head 10, and more specifically inside said aforementioned control portion 10B, said stationary portion 23 carries at least one second peripheral wall 24. By "peripheral", it is here advantageously understood that said second peripheral wall 24 is carried by said stationary portion 23 of the control system by following at least part (and preferably all) of an external contour of said stationary portion 23, that is to say at least part (and preferably all) of a perimeter (or contour) of a section of said stationary portion 23 which extends in a mean plane intersecting the axis B-B' of mean extension of the blowing head 10 (an identical definition applies mutatis mutandis for the fourth and eighth peripheral walls 39, 52A, 52B which will be mentioned later). Preferably, the second peripheral wall 24 has an annular shape.

[0049] As illustrated by example in Figures 6 to 12, the first peripheral wall 22 is arranged in contact with said second peripheral wall 24, and with at least partial (and preferably substantially total) surface overlap of the latter, to oppose the passage of air from said air flow F from said first portion 10A of the housing 6A of the blowing head 10 through said second portion 10B of said housing 6A, at least in a mean direction (or “mean leakage direction”) parallel to said mean inlet direction of the air flow F. Advantageously, said first peripheral wall 22 is arranged in contact with said second peripheral wall 24, and with at least partial (and preferably substantially total) surface overlap, along the entire respective length of said first and second peripheral walls 22, 24.In other words, the first and second peripheral walls 22, 24 cooperate to form at least one airtight barrier, to prevent air leakage, coming from said aeraulic portion 10A of the housing 6A of the blowing head 10, through said control portion 10B of said housing 6A. By "in contact", we advantageously expect here, as well as in everything that follows, at least a point contact, if not a surface contact, taking into account an inevitable functional clearance that can exist between the parts (typically of the order of 0.1 mm to 0.3 mm approximately).

[0050] Said first peripheral wall 22 therefore has at least one face, which is arranged in contact with a corresponding face that is respectively presented by said second peripheral wall 24, and with at least partial (and preferably substantially total) surface overlap of this corresponding face. Said face of the first peripheral wall 22 is therefore arranged opposite said corresponding face of the second peripheral wall 24, and in contact (preferably plane on plane) with said corresponding face. The respective faces of the first and second peripheral walls 22, 24 advantageously each extend along a mean plane of extension that is secant to said mean direction of entry of the air flow F. For example, the first peripheral wall spherical 22 is formed in whole or in part by a first peripheral tongue (or rib) which projects from said internal face 21. Advantageously, said first peripheral tongue is made of one piece with one or more cover pieces forming the housing 6A of the blowing head 10 (figures 6 to 12, 15 and 16). For example, the second peripheral wall 24 is reciprocally formed in whole or in part by a second peripheral tongue (or rib) which projects from an external face of said stationary portion 23 of the control system in the direction of the internal face 21 of the housing 6A of the blowing head 10. Advantageously, said second peripheral tongue is made of one piece with one or more pieces forming the stationary portion 23 of the control system (figures 6 to 12, 15 and 16).As understood from the above, said stationary portion 23 of the control system is therefore arranged at a distance from the internal face 21 of the housing 6A of the blowing head 10, so that the first and second peripheral walls 22, 24 (and therefore said airtight barrier) are arranged in a free internal space provided between the stationary portion 23 of the control system and the internal face 21 of said housing 6A. By their cooperation, the first and second peripheral walls 22, 24 therefore oppose a passage of air through said free space. For example, said stationary portion 23 of the control system is arranged aligned along the axis B-B' of average extension of the blowing head 10.

[0051] Thanks to the particular combination of the aforementioned characteristics, the multi-mode blowing hairdressing appliance 1 is thus of particularly efficient aeraulic design, while being particularly practical to use. The implementation of an airtight barrier as described above in fact makes it possible to particularly effectively reduce, if not completely, a risk of air leakage towards the control portion of the blowing head 10 despite the presence of the control system connected to the air distribution member 18. The improvement in the aeraulic efficiency of the hairdressing appliance 1 advantageously allows the implementation of a less powerful blower module 13, and therefore less bulky, less noisy or even less expensive.In addition, the implementation of such an airtight barrier makes the design and manufacture of the hairdressing appliance 1 particularly simple and inexpensive, insofar as it becomes possible in particular to avoid implementing one or more elastomer sealing joints between the housing 6A of the blowing head 10 and said stationary portion 23 of the control system, which would then constitute additional parts distinct from the housing 6A and from said stationary portion 23. The fact that the second peripheral wall 24 is carried by a portion 23 of the control system which is advantageously stationary relative to the housing 6A of the blowing head 10, and is therefore not carried by a portion of the control system which is movable relative to said housing 6A, contributes as such to . the effectiveness of the air leak barrier effect, but also to the simplicity of design of the hairdressing appliance 1 (absence of relative movement). In addition, the implementation of an airtight barrier advantageously contributes to the ease and safety of use of the hairdressing appliance 1 in the case where the latter comprises, as envisaged above, a heating element for raising the temperature of the air flow F. Indeed, by ensuring effective limitation of hot air leaks towards the second portion 10B of the housing 6A of the blowing head 10, such an airtight barrier advantageously makes it possible to define, in a simple and effective manner, an end portion of the blowing head 10 forming a “cold tip” (or “cool tip” in English), by means of which the user can grasp or manipulate the hairdressing appliance 1, in particular during a styling operation.In particular, as will be seen in the following, such a design advantageously makes the handling of the control system by the user not only easy, but also particularly safe.

[0052] Preferably, as in the embodiment illustrated in the figures, the air distribution member 18 is designed and configured so that the average direction of entry of the air flow F is parallel to, or coincides with, the axis B-B' of average extension of the blowing head 10, so that said average direction of leakage is itself parallel to, or coincides with, the axis B-B' of average extension of the blowing head 10. In return, the first and second peripheral walls 22, 24 each extend, generally, along a mean plane of extension which is orthogonal to said axis B-B' of average extension of the blowing head 10. In other words, the respective faces of the first and second peripheral walls 22, 24, which are arranged in contact and overlapping one another, therefore each preferably extend along a mean plane extension which is orthogonal to said axis B-B' of average extension of the blowing head 10.Such an arrangement, rather than an arrangement obliquely relative to said axis B-B' of average extension, contributes not only to further improving the effectiveness of the aforementioned barrier effect, but also to simplifying the design and manufacture of the hairdressing appliance 1. .

[0053] The air direction member 18 preferably comprises a side wall (airtight), which extends along an axis E-E' of average extension of the air direction member 18 between a first end carrying, defining, the air inlet 19 of the air direction member 18, and a second opposite end closed (and therefore airtight). Advantageously, the axis E-E' of average extension of the air direction member 18 is substantially parallel to, or coincident with, said average direction of entry of the air flow F. Depending on the conformation and the dimensioning of the air direction member 18, the axis E-E' of average extension of the latter may constitute, as illustrated in the figures, an axis E-E' of average longitudinal extension of the air direction member 18. Advantageously, the air direction outlet 20 of the latter is arranged, for example in the form of a light, through the side wall of the air direction member 18 and extends for example longitudinally along the axis E-E' of average extension of the air direction member 18 (but not necessarily parallel to said axis E-E' of average extension). Thus, as mentioned above, the air direction outlet 20 is therefore advantageously designed and configured so that the air flow F entering through the air inlet 19 exits through the air direction outlet 20 in a mean outlet direction which is secant to (or at least arranged in an inclined manner relative to) said mean inlet direction in which the air flow F enters the air direction member 18 through said air inlet 19 (Figures 6 and 8).As illustrated by way of example in the figures, the side wall of the air direction member 18 defines a hollow internal shape whose section preferably narrows from the first end towards the second end of said side wall. Thus, the air direction member 18 therefore advantageously forms an air direction duct, defined by said side wall, whose general internal shape is preferably generally frustoconical. In other words, the air direction member 18 advantageously comprises a hollow tube of generally frustoconical internal shape, defined by said side wall. Said hollow tube typically has an axis of revolution which is advantageously formed by, or parallel to, the axis E-E' of average extension of the air direction member 18. The average extension axis E-E' of the air direction member 18 is advantageously coincident with the average extension axis B-B' of the blowing head 10. The respective extension axes B-B', E-E' of the blowing head 10 and of the air direction member 18 are advantageously collinear with the average longitudinal extension axis A-A' of the handle 7. The first end of said side wall X therefore defines a large base of the internal general shape which is generally frustoconical, by means of which the air flow F enters the air direction member 18. Such a hollow internal shape, the section of which narrows from the first end towards the second end of the side wall, advantageously makes it possible to homogenize the profile of the air flow F which circulates inside the air direction member 18, and therefore to further improve the aeraulic performance of the device. hairstyle 1.In the case where, as illustrated in the figures, the hairdressing appliance 1 comprises a guide channel 15 arranged inside the handle 7 to guide the air flow F to the blowing head 10, said guide channel 15 then typically has an air outlet end 26 to which is connected to the air inlet 19 of the air directing member 18, and which is therefore opposite an air inlet end of the guide channel 15 which is connected to the blowing module 13.

[0054] Advantageously, as in the embodiment illustrated in the figures, the hairdressing appliance 1 comprises an internal ducting device 27 which defines at least in part a first duct portion 28 to ensure airflow communication between the air direction outlet 20 of the air direction member 18 and the first air blowing outlet 2 when the air direction member 18 occupies the first air direction configuration, and a second duct portion 29 to ensure airflow communication between said air direction outlet 20 and the second air blowing outlet 3 when the air direction member 18 occupies the second air direction configuration. Said internal ducting device 27 thus advantageously constitutes a “two-way” internal ducting device (or “two-way distributor”).The internal ducting device 27 is arranged immobile in the housing 6A of the blowing head 10, and in particular at least in the aeraulic portion 10A of said housing 6A. In return, the air direction member 18 is arranged movably in the internal ducting device 27 between the first and second air direction configurations. Thus, when the air direction member 18 occupies the first air direction configuration, the air direction outlet 20 of the air direction member 18 is in aeraulic communication with the first duct portion 28, and therefore with the first air blowing outlet 2. On the other hand, the air direction member 18 (for example, the side wall of the latter) then closes the second duct portion 29 ([Fig. 6]).Conversely, when the air direction member 18 occupies the second air direction configuration, the air direction outlet 20 of the air direction member 18 is in air communication with the second portion of duct 29, and therefore with the second air blowing outlet 3. The air direction member 18 (for example, the side wall of the latter) then closes the first portion of duct 28 ([Fig.8]).

[0055] Typically, said internal ducting device 27 defines an internal space, which opens out of the internal ducting device 27, on the one hand in the direction of the first air blowing outlet 2 via said first duct portion 28 and in the direction of the second air blowing outlet 3 via said second duct portion 29, and on the other hand, by an inlet opening (distinct from said duct portions 28, 29), via which the air flow F enters the internal ducting device 27. Advantageously, as in the embodiment illustrated in the figures, the first duct portion 28 has a useful air passage section which decreases continuously in the direction of the first air blowing outlet 2.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 3. This advantageously contributes to. facilitate the circulation of the air flow F towards the first air blowing air outlet 2, respectively towards the second air blowing air outlet 3, and therefore reduce a risk of air blocking and of an increase in the air pressure inside said air portion of the blowing head 10, as well as the risk of air (possibly hot) leaking out of said air portion 10A.

[0056] The air direction outlet 20 of the air direction member 18 is advantageously provided with a plurality of air deflectors 30 (straightening vanes), called "primary deflectors", for straightening the air flow F exiting through the air direction outlet 20 from the air inlet 19 of the air direction member 18, and for optimally guiding the air flow F towards the first air blowing outlet 2 or the second air blowing outlet 3, depending on the blowing mode selected. In a particularly advantageous manner in terms of optimal straightening and guiding of the air flow F, the blowing head 10 may further comprise: - first outlet air deflectors 31 (“first secondary air deflectors”) for straightening the air flow F directed towards the first air blowing outlet 2 coming from the air direction outlet 20 of the air direction member 18 when the latter is in said first air direction configuration, and - second outlet air deflectors 32 (“second secondary air deflectors”) for straightening the initiated air flow F directed towards the second air blowing outlet 3 coming from the air direction outlet 20 of the air direction member 18 when the latter is in said second air direction configuration.

[0057] A plurality of said air deflectors 30 of the air direction outlet 20 of the air direction member 18 is then arranged aligned with a plurality of said first outlet air deflectors 31 when the air direction member 18 is in said first air direction configuration (Figures 6 and 7), and a plurality of said air deflectors 30 of the air direction outlet 20 of the air direction member 18 being respectively arranged aligned with a plurality of said second outlet air deflectors 32 when the air direction member 18 is in said second air direction configuration ([Fig.8]).Such selective relative alignment of the primary air deflectors and first or second secondary air deflectors, as described above, contributes in particular to optimizing, homogenizing, in a particularly effective manner the blowing of the air flow F out of the hairdressing appliance 1 towards the hair, regardless of the air blowing outlet 2, 3 used. It further contributes to facilitating the flow of the air flow F out of the hairdressing appliance 1 and therefore to avoiding a risk of blocking the air and increasing the air pressure inside said aeraulic portion of the blowing head 10, as well as the . risk of air leakage (possibly hot) from said airflow portion.

[0058] Different kinematics of the air direction member 18 and of the blowing head can be envisaged, depending in particular on the conformation and configuration of the air direction member 18. Preferably, however, in terms of simplicity of design and use of the hairdressing appliance 1, the blowing head 10 is connected immobile to the handle 7 of the hairdressing appliance 1, and the air direction member 18 is mounted mobile relative to the blowing head 10 and to the handle 7 between the 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 18 and the blowing head 10 are preferably mounted to be mobile in rotation, in pivoting, along an axis D-D' of rotation, relative to each other between at least said first and second air direction configurations.Preferably, said axis D-D' of rotation coincides with (collinear to), or at least parallel to, the axis E-E' of average extension of the air direction member 18, which is itself advantageously coincident with (collinear to) the axis B-B' of average extension of the blowing head 10. According to a variant (not illustrated), the air direction member 18 is connected immobile relative to the handle 7, and the blowing head 10 is then mounted to be able to rotate, along said axis D-D' of rotation, relative to the air direction member 18 and the blowing head 10. According to another variant, implemented in the embodiment illustrated in the figures, the air direction member 18 is mounted to be able to rotate, along said axis D-D' of rotation, inside the housing 6A of the blowing head 10 between the first and second direction configurations. air. The blowing head 10 is then advantageously connected immobile to the handle 7.In accordance with the above, this second variant proves to be preferable insofar as it contributes to making the hairdressing appliance 1 simpler to design and use. Thus, as illustrated in the figures, the air direction member 18 is preferably arranged to be movable in rotation, along said axis D-D' of rotation, in the internal channeling device 27 between the first and second air direction configurations.

[0059] Advantageously, the system for controlling the change of blowing mode of the hairdressing appliance 1 comprises a manual control member, for example a button 33 or a wheel, to allow the user to act on said control system, and therefore to manually select alternately one or the other of said blowing modes. Said manual control member is therefore advantageously mobile, that is to say that it is able to evolve between at least two advantageously predefined positions and / or spatial orientations (relative to the rest of the hairdressing appliance 1 and in particular relative to the housing 6A of the blowing head 10), typically by translation, rotation and / or by tilting under the effect of a manual mechanical action exerted against it by the user. In view of the above, the manual control member is therefore arranged at the level of the blowing head 10, that is to say that it is carried by (or that it belongs to) the blowing head 10, and in particular by said control portion of the housing 6A of the latter, and not at the level of the handle 7. As such, 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 7. More preferably, the manual control member is arranged at such a distance from the handle 7 that it cannot be reached by a finger of the hand of the user who is holding the handle 7. Inaccessible to a finger of the hand of the user who is holding the handle 7, 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 B-B' of average extension of the blowing head 10, so that it is therefore accessible to the user from above the blowing head 10 (and therefore not via one or the other of the first and second faces of the latter). Advantageously, said stationary portion 23 of the control system forms a part for guiding and / or fixing said manual control member. In other words, said stationary portion 23 constitutes a portion of the control system which ensures guidance of the manual control member, in particular during its manipulation by the user, and / or which ensures fixing (advantageously permanent) of the manual control member to the rest of the control system.This helps to make the design and operation of the control system simpler, more reliable and more robust.

[0060] According to an advantageous variant, implemented in the embodiment illustrated in the figures, the control system of the hairdressing appliance 1 is a push-push button control mechanism 33 (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 is therefore designed and configured to transform each push exerted by the user (typically using a finger of the user) on the button 33 of the control system 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 33 of the control system then advantageously forms the manual control member mentioned above. As illustrated in the figures, the push-push button control mechanism 33 is thus advantageously connected to the member. air direction 18 for controlling each passage of the air direction member 18 from one to the other of the first and second air direction configurations mentioned above. The button 33 of the push-push button control mechanism 33 typically has a contact portion 34, or interaction portion, intended to come into direct contact with the user, and in particular with a finger of the latter, so that the user exerts a push against the button 33 to control the change of blowing mode. Said contact portion 34 therefore defines an external surface portion of the button 33, oriented towards the outside of the hairdressing appliance 1, and accessible to and visible to the user from outside the hairdressing appliance 1.Advantageously, as illustrated in the figures, said contact portion 34 defines a free upper end of the button 33, which is opposite a lower end of the button 33 which is arranged (permanently) inside the hairdressing appliance 1. As such, the button 33 therefore advantageously forms said movable manual control member to allow the user to act on the control mechanism.

[0061] Thanks to such a push-push button 33 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 33 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 33 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 actuated successively as many times as the hairdressing appliance 1 has different blowing modes.In the event that the means for generating the air flow F of the hairdressing appliance 1 are provided to generate the air flow F according to only two different blowing modes, each push exerted by the user on the button 33 thus controls the alternating passage from a first operating mode of the hairdressing appliance 1 (first blowing mode) to a second operating mode of the hairdressing appliance 1 (second blowing mode), then from the first operating mode to the second operating mode of the hairdressing appliance 1, and so on.

[0062] The hairdressing appliance 1 advantageously comprises a housing 35, which is provided with an access opening 36, inscribed in an opening plane, and through which said housing typically opens from an external surface of the hairdressing appliance 1. As illustrated in the figures, it is therefore an internal housing 35, arranged inside the hairdressing appliance 1, and in particular therefore inside the second portion 10B (control portion) of the housing 6A of the blowing head 10, and which is open towards the outside of the hairdressing appliance 1 via said access opening 36. Typically, the access opening 35 is delimited by the housing 6A of the blowing head 10, that is to say that the access opening 36 forms a hole in the housing 6A. Said access opening 36, and in particular a peripheral edge of the latter, advantageously defines said free upper end of the blowing head 10. The button 33 of the push-push button control mechanism 33 is advantageously mounted movably, in said housing 35, in translation towards the inside of said housing 35 in a translation direction C-C', preferably orthogonal to the opening plane, between: - a first stop position, called the released position (or “high position” or “rest position”), which advantageously constitutes a stable (released) position (figures 1 to 3, 5 to 10, 12 and 17), and - a second stop position, called the pressed position (or “low position” or “activation position”) (figures 4, 11 and 18), in which the contact portion 34 of the button 33 is arranged inside said housing 33.

[0063] Advantageously, as illustrated by example in the figures, said housing 35 thus extends longitudinally (axially) from said access opening 36 towards the inside of the blowing head 10 of the hairdressing appliance 1, in said translation direction C-C' of the button 33. Said released position and pressed position constitute extreme positions of the button 33 relative to the housing 35, and define a maximum travel of movement of the button 33 in translation in said translation direction C-C'. In general, the control mechanism can be designed and configured so that, in the released position, the contact portion 34 of the button 33 is arranged above, flush with, or below the external surface of the hairdressing appliance 1 (and therefore typically above, flush with, or below the opening plane of the access opening 36 to the housing 35).Preferably, however, as illustrated in the figures, the control mechanism is designed and configured so that the contact portion 34 of the button 33 is (entirely) arranged outside the housing 6A of the blowing head 10, when the button 33 is in the released position, that is to say that the contact portion 34 of the button 33 is then arranged above the external surface of the housing 6A of the blowing head 10. Thus, in the released position and therefore in the absence of thrust exerted on the button 33, the latter advantageously extends projecting from the external surface of the blowing head 10, typically projecting from the external surface of the housing 6A of the latter. This makes it easier to visually and / or tactilely identify the button 33, to access the button 33 and to manipulate the latter by the user. In any event, the control mechanism is advantageously designed and configured. such that the contact portion 33 of the button 33 is arranged below the external surface of the hairdressing appliance 1 (and therefore below the opening plane of the access opening 36 to the housing 35), once the button 33 has reached said depressed position under the effect of a push exerted by the user to switch the hairdressing appliance 1 from one blowing mode to another. In other words, the button 33 retracts, retracts, entirely inside the housing 35 and therefore the hairdressing appliance 1, when the button 33 moves towards and up to the depressed position. It is thus necessary for the user, to control a change of blowing mode of the hairdressing appliance 1, to introduce at least one of his fingers into the housing 35 via the access opening 36 to the latter.The risk of an involuntary change of the blowing mode by interaction of the button 33 with the user or with a surrounding element is thus particularly limited.

[0064] Ensuring effective limitation of hot air leaks, towards the second portion 10B of the housing 6A of the blowing head 10, the implementation of first and second peripheral walls 22, 23 as described previously allows particularly safe and comfortable handling of the button 33 (manual control member of the control system), since the temperature of the housing 35 and of the contact portion 33 of the button 33 can thus be kept sufficiently low so as not to generate a risk of discomfort or burning for a user's finger.

[0065] Preferably, the housing 35 has a button guide portion 21, which is delimited by a tubular side wall 37, preferably solid (i.e. not perforated), along which the contact portion 34 of the button 33 moves when the button 33 translates from said released position to the pressed position (and vice versa from said pressed position to said released position). As such, said button guide portion 33 therefore belongs to said control system. Said guide portion thus advantageously extends from the access opening 36 to said housing 35 towards the inside of the hairdressing appliance 1, in an extension direction advantageously parallel to the translation direction C-C' of the button 33.Thus, said guide portion advantageously constitutes at least a portion of the housing 35 which is closed laterally, which thus advantageously makes it possible to isolate the contact portion 34 from the button 33.

[0066] Advantageously, the internal face 21 of the housing 6A of the blowing head 10 carries at least a third peripheral wall 38, and said tubular side wall 37 carries in return at least a fourth peripheral wall 39. Said third and fourth peripheral walls 38, 39 are then arranged in contact with one another and with (at least partial) surface overlap of one another, to oppose the passage of air from said air flow F in the direction of the free upper end of the blowing head 10 at least in a mean direction parallel to said mean direction of entry of the air flow F. In other words, the third and fourth peripheral walls 38, 39 cooperate to thus form at least one airtight barrier, to prevent air leakage towards the free upper end of the blowing head 10 at least in a mean direction parallel to said mean direction of entry of the air flow F. In particular, the risk of air leakage between the internal face 21 of the housing 6A of the blowing head 10 and the tubular side wall 37, and therefore in particular of potential heating of the latter, is thus further limited.The third peripheral wall 38 therefore has at least one face, which is arranged in contact with a corresponding face that the fourth peripheral wall 39 respectively has, and with at least partial (and preferably substantially total) surface overlap of this corresponding face. Said face of the third peripheral wall 38 is therefore arranged opposite said corresponding face of the fourth peripheral wall 39, and in contact (preferably plane on plane) with said corresponding face. The respective faces of the third and fourth peripheral walls 38, 39 therefore each extend along a mean plane of extension that intersects said mean direction of entry of the air flow F. For example, the third peripheral wall 38 is formed in whole or in part by a third peripheral tongue (or rib) that extends projecting from said internal face 21.Advantageously, said third peripheral tongue is integral with one or more cover pieces forming the housing 6A of the blowing head 10. For example, the fourth peripheral wall 39 is reciprocally formed in whole or in part by a fourth peripheral tongue (or rib) which extends projecting from an external face of said tubular side wall 37 in the direction of the internal face 21 of the housing 6A of the blowing head 10. Advantageously, said fourth peripheral tongue is integral with one or more pieces forming the tubular side wall 37. Preferably, for the reasons explained in connection with the first and second peripheral walls 22, 23, said third and fourth peripheral walls 38, 39 each extend, in a general manner, along a mean extension plane which is orthogonal to said axis B-B' of mean extension of the blowing head 10.In other words, the respective faces of said third and fourth peripheral walls 38, 39, which are arranged in contact and overlapping one another, therefore each preferably extend along a mean extension plane which is orthogonal to the axis B-B' of mean extension of the blowing head 10. Preferably, the third peripheral wall 38 has an annular shape. Preferably, the fourth peripheral wall 39 has an annular shape.

[0067] As illustrated in the figures, the tubular side wall 37 typically extends from a lower end towards the access opening 36 to said housing 35. particularly advantageously, the lower end 40 of said tubular side wall 37 is arranged in contact with an upper face of the first peripheral wall 22, and this advantageously along the entire length of said first peripheral wall 22. In return, the second peripheral wall 24 is arranged in contact with an opposite lower face of said first peripheral wall 22, and at least partially overlapping the latter (i.e. at least partially overlapping said lower face), and this advantageously along the entire respective length of said first and second peripheral walls 22, 24. In this way, said first peripheral wall 22 is tightly interposed, sandwiched, between said tubular side wall 37 and said corresponding second peripheral wall 24, which makes it possible to further improve the air barrier effect of the first and second peripheral walls 22, 24 (Figures 6 to 12, 17 and 18).This therefore contributes to further reinforcing the aeraulic efficiency and the safety of use of the hairdressing appliance 1. Alternatively, the lower end 40 of the tubular side wall 37 can be arranged in contact with an upper face of the second peripheral wall 24, and this advantageously along the entire length of the latter. In return, the first peripheral wall 22 is then arranged in contact with an opposite lower face of the second peripheral wall 24, and at least partially overlapping the latter (i.e. at least partially overlapping said lower face), and this advantageously along the entire respective length of the first and second peripheral walls 22, 24.

[0068] Advantageously, the push-push button control mechanism 33 is designed and configured to control in a purely mechanical manner each passage of the air direction member 18 from one to the other of said first and second air direction configurations, and therefore each passage of the hairdressing appliance 1 from one of the blowing modes to another of the blowing modes. The control mechanism is therefore designed and configured to mechanically transform each push exerted by the user (for example using a finger of the user) on the button 33 of the control mechanism into a passage 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 push-push button control mechanism 33 is therefore advantageously free of electrical or electromechanical components, so that its design is particularly simple, economical and reliable. As in the embodiment illustrated in the figures, the button 3 of the push-push button control mechanism is thus advantageously mechanically connected to the air direction member 18 to mechanically transform each movement of the button 33 of the push-push button control mechanism under the effect of a push exerted on the button 33 (by the user) into a relative movement of the air direction member 18. relative to the blowing head 10 from one to the other of the first and second air direction configurations. It is therefore advantageously not an electromechanical push-push button control mechanism, which would establish an electromechanical connection between the button of the control mechanism and the air direction member, that is to say which would be designed to transform a mechanical push exerted on the button by the user into an electrical command of an electric actuator which would be connected to the air direction member 18. The implementation of such a purely mechanical control mechanism advantageously allows the user to modify the blowing mode of the hairdressing appliance 1 even when the latter is not powered on (that is to say when the hairdressing appliance 1 is stopped, or even unplugged).The safety of use of the hairdressing appliance 1 is thereby improved, insofar as the risk of immediate air blowing in a direction not expected by the user, for example towards his face, is thus limited. The hairdressing appliance 1 nevertheless remains simple to use, since the user retains the possibility of changing the blowing mode of the hairdressing appliance 1 while the latter is in operation. Furthermore, the implementation of a purely mechanical control of the change of blowing mode, rather than an electromechanical control, tends to improve the operational reliability of the hairdressing appliance 1, and to reduce its manufacturing and operating costs.

[0069] According to a variant (not illustrated), the button of the push-push button control mechanism is a bistable button. Typically, the control mechanism is then designed and configured so that the button is able to move from a first stable position (released position) to a second unstable position (called unstable depressed position) under the effect of a first push exerted by the user, and then to return automatically to a third stable position (called stable depressed position), intermediate to said first stable position and second unstable position, under the effect of an elastic return member when the first push exerted by the user ceases. The button then remains temporarily locked in said stable depressed position, corresponding to one of the blowing modes of the hairdressing appliance 1.Conversely, the control mechanism is then designed and configured so that the button is able to move from the third stable depressed position to the second unstable depressed position under the effect of a second push exerted by the user, which is consecutive to the first push and which thus makes it possible to unlock the button, and to then return to the first stable released position, under the effect of an elastic return member, when the second push exerted by the user ceases. For example, such a bistable push-push button control mechanism can implement a mechanism, a kinematic, called "cardioid". According to a more preferred variant, implemented in the mode of . embodiment illustrated in the figures, the button 33 of the push-push button control mechanism 33 is a monostable button. The control mechanism is therefore preferably designed and configured so that the button 33 is able to move from a first stable position (released position) to a second unstable position (pressed position) under the effect of a push exerted by the user, and then to return automatically from the pressed position to the released position when the push exerted by the user ceases, under the effect of an elastic return member 41. This “monostable” variant proves to be more advantageous than the aforementioned “bistable” variant insofar as, since the button 33 systematically returns to the released position, it remains as accessible to the user regardless of the blowing mode selected. In addition, such a “monostable” variant is simpler to design and more robust in use.Whatever the “bistable” or “monostable” variant envisaged, the push-push button control mechanism 33 therefore advantageously comprises at least one elastic return member 41 to automatically return the button 33 from the pressed position to the released position. Preferably, said elastic return member 41 is a spring, and in particular a tension, compression or flexion spring (leaf spring).

[0070] As in the embodiment illustrated in the figures, the contact portion 34 of the button 33 is preferably provided with a concave zone, i.e. an area having a concavity oriented towards the outside of the hairdressing appliance 1. The presence of such a concave zone, preferably positioned in the center of said contact portion 34, advantageously makes it possible to guide the placement of an end of a fingertip, and in particular a portion of fingertip, on the contact portion 34 of the button 33, to help keep the finger thus positioned for the effective application of a pushing force against the button 33 to control the change of blowing mode, and this even in particular without visual contact with the button 34.

[0071] According to a variant (not illustrated), the control mechanism can be designed and configured to transform each push exerted by the user on the button of the control mechanism into a change of the hairdressing appliance 1 from one of the blowing modes to another of the blowing modes. In this case, the single push exerted by the user on the button of the control mechanism makes it possible to change the hairdressing appliance 1 from one of the blowing modes to another of the blowing modes. Once the hairdressing appliance 1 affects this other blowing mode, the user can then stop exerting his pushing force on the button. According to another more preferred variant, implemented in the embodiment illustrated in the figures, the control mechanism is designed and configured to transform each push, exerted by the user, on the button 33 of the control mechanism in a passage of the hairdressing appliance 1 from one of the blowing modes to another of the blowing modes, then to automatically finalize the passage of the hairdressing appliance 1 to the other of the blowing modes under the effect of the automatic return of the button 33 to said stable released position, when the thrust exerted by the user ceases. In other words, the change of blowing mode is then initiated only by pressure exerted by the user on the button 33, then automatically completed by the control mechanism. This allows in particular an easier, more intuitive and faster change of blowing mode for the user.

[0072] When, as in the embodiment illustrated in the figures, the air direction member 18 is advantageously mounted to be movable in rotation, in pivoting, along said axis D-D' of rotation, between at least the first and second air direction configurations, the control system, and for example the push-push button control mechanism 33 mentioned above, then controls the passage of the air direction member 18 from one to the other of the first and second air direction configurations by rotation of the air direction member 18 according to a predetermined angle of rotation along said axis D-D' of rotation. More preferably, the air direction member 18 is mounted to be able to rotate relative to the handle 7 of the hairdressing appliance 1, the axis D-D' of rotation of the air direction member 18 being preferably parallel to, or more preferably merged with, the axis A-A' of longitudinal extension of the handle 7.

[0073] In order to ensure a mechanical connection, as mentioned above, between the button 33 of the push-push button control mechanism and the air direction member 18, and thus to transmit to the latter the mechanical pushing force exerted by the user on the button 33, the control mechanism preferably comprises a rotary coupling part 42, forming a cam and mechanically connected to the air direction member 18 on the one hand, and preferably on the other hand to the button 33. The button 33 is advantageously secured to at least one pin 43 (or roller) forming a follower which cooperates with the cam so that each push exerted on the button 33 causes the rotary coupling part 42 to rotate about an axis of rotation and a corresponding rotation of the air direction member 18 about its axis D-D' of rotation.Preferably, as in the embodiments illustrated in the figures and as mentioned previously, the button 33 of the push-push button control mechanism 33 is mounted in rectilinear translation, and more preferably in pure rectilinear translation, in said translation direction C-C', relative to the rest of the hairdressing appliance 1, and in particular relative to the housing 6A of the blowing head 10, between said released position and said pressed position. Thus, the movement of the button 33 under the effect . of a thrust exerted by the user is a pure rectilinear translational movement, that is to say according to a rectilinear sliding connection, of the same average direction as the thrust force exerted by the user. The manipulation of the button 33 is thus particularly easy and intuitive for the user, and this whatever the position and orientation of the button 33 relative to the user in use of the hairdressing appliance 1. Alternatively, although less advantageously in terms of simplicity of design and size, but also in terms of ergonomics, the button could for example be mounted to rotate or pivot, to rock, and be shaped and configured so that the contact portion of the button describes a curvilinear trajectory in an arc of a circle under the effect of the thrust exerted by the user.Even more preferably, the button 33 is arranged relative to the rotary coupling part 42 in such a way that the direction C-C' of rectilinear translation of the button 33 coincides with the axis of rotation of the rotary coupling part 42. Thus, each push exerted by the user on the button 33 causes a rectilinear translational movement of the button 33 and, preferably directly, a rotation of the rotary coupling part 42 in the direction C-C' of translation of the button 33, according to a design which is particularly simple and compact due to the preferential absence of an intermediate part between the button 33 and the rotary coupling part 42. Alternatively, the direction C-C' of rectilinear translation of the button 33 could be provided parallel to the axis of rotation of the rotary coupling part 42 and offset relative to the latter, or else provided oblique or orthogonal to the axis of rotation of the rotary coupling part 42, to the detriment, however, of the simplicity of design and the compactness of the control mechanism.Advantageously, the rotary coupling part 42 is immobilized in rotation relative to the air direction member 18, the axis of rotation of the rotary coupling part 42 being coincident with the respective axis D-D' of rotation of the air direction member 18. Thus, each movement of the button 33 under the effect of a thrust exerted by the user causes a joint rotation of the rotary coupling part 42 and the air direction member 18, of said predetermined angle of rotation, according to a common axis of rotation. This contributes to the simplicity and reliability of design and operation of the hairdressing appliance 1. For example, as illustrated in the figures, the rotary coupling part 42 and the air direction member 18 can be assembled to each other by form fit and secured to each other by screwing or by clipping / snap-fastening or gluing.Alternatively, the rotary coupling part 42 and the air direction member 18 could possibly together form a monolithic part.

[0074] Preferably, as in the embodiment illustrated in the figures, the rotary coupling part 42 more specifically forms a grooved drum cam. The rotary coupling part 42 thus comprises at least one cylindrical portion of revolution, which is provided with a groove 44 forming a cam path delimited by two opposite side walls of the groove 44 and intended to be traveled by the pin 43 forming a follower secured to the button 33. The pin 43 is thus captive within the groove 44, which contributes to ensuring a reliable mechanical connection between the button 33 and the rotary coupling part 42. Even more preferably, the groove 44 is peripheral, extending along the entire periphery of the cylindrical portion of revolution, and closed on itself. The rotation of the rotary coupling part 42 about its axis of rotation can thus be done in the same direction of rotation at each command to change the air direction configuration, and therefore the blowing mode.

[0075] For example, in the embodiment illustrated in the figures, the button 33 is mounted in rectilinear translation (pure) its translation direction C-C' (sliding connection), which is coincident with the axis of rotation of the rotary coupling part 42. Preferably, the direction C-C' of rectilinear translation is parallel to, or coincident with, the axis B-B' of average extension of the blowing head 10, said axis B-B' of average extension itself being advantageously parallel to, or coincident with, the axis D-D' of rotation of the air direction member 18, said axis D-D' of rotation itself being advantageously parallel to, or coincident with, the axis A-A' of average longitudinal extension of the handle 7. This thus advantageously results, in particular when the four axes and directions A-A', B-B', C-C', D-D' mentioned above are coincident, a particularly simple construction and a particularly compact hairdressing appliance 1.The button 33 advantageously comprises a portion of lateral skirt 45 of circular section, of revolution in the direction C-C' of rectilinear translation, which is arranged parallel to the cylindrical portion of revolution of the rotary coupling part 42, at least partially overlapping said cylindrical portion. The button 33 is connected not to a single pin 43, but to two pins 43 forming followers, arranged on either side of the direction C-C' of rectilinear translation, in order to further make the mechanical connection between the button 33 and the rotary coupling part 42 more reliable. A free end portion of each of the pins 44 is housed in the groove 44 of the grooved drum cam formed here by the rotary coupling part 42.

[0076] In order to ensure rotational locking of the button 33 relative to the rest of the hairdressing appliance 1, and in particular relative to the blowing head 10 of the latter, and to guide the translational movement of the button 33 in the rectilinear translation direction C-C', a portion of each of the pins 43 is housed within a respective oblong guide slot 46 formed in said stationary portion 23 of the control system. As in the embodiment illustrated in the figures, said stationary portion 23 of the control system can advantageously form a part integral with the aforementioned internal channeling device 37 (figures 13 and 14). For example, said stationary portion 23 may have a generally tubular shape, inside which the rotary coupling part 42 is housed, and in which the lateral skirt portion 45 of the button 33 slides in translation (figures 13 and 14). Thus, as previously envisaged, the stationary portion 23 of the control system here forms a guide and fixing part of the button 33 (manual control member).To facilitate assembly of the hairdressing appliance 1, the pins 43 may each be defined by a cylindrical pin force-fitted into an orifice provided through the wall of the side skirt portion 45 of the button 33, once the button 33 is assembled to overlap the cylindrical portion of revolution of the rotary coupling part 45, such that a portion of the pins defining such a follower-forming pin X extends radially inside the button 33, while an opposite portion of the pins extends radially outside the button 33 and is captured in one of the oblong guide slots 46.

[0077] Advantageously, the push-push button control mechanism 33 comprises an elastic return member 41, as already mentioned previously, such as for example a compression spring. The elastic return member 41 is configured and arranged to automatically return the button 33 to its stable released position (unpressed position) when the user stops pushing on the button 33. As illustrated in the figures, the compression spring may be arranged between an inner surface of the button 33 and a surface of the rotary coupling part 41.The cam formed by the rotary coupling part 42 is preferably shaped and configured so that the rotation of the air direction member 18 according to said predetermined angle of rotation, which allows the hairdressing appliance 1 to switch from one blowing mode to another by a corresponding change of the air direction member 18 from one air direction configuration to another, is carried out for only a first part of said predetermined angle of rotation, by a movement of the button 33 of the push-push button control mechanism under the effect of a push exerted by the user on the button 33, then, for the remainder of said predetermined angle of rotation, by a movement in the opposite direction of the button 33 under the joint effect of the elastic return member 41 and the cam, when the push exerted by the user ceases.Thus, the change of blowing mode is only initiated by a push exerted by the user on the button 33, as mentioned previously as a preferred variant, the change of blowing mode being finalized automatically by the control mechanism, after the user has stopped pushing on the button 33 of the latter. The user therefore advantageously only needs to provide a part of the force necessary to rotate the air direction member 18 according to the angle . of predetermined rotation to move the latter from one to the other of its air direction configurations. As indicated above, this allows in particular an easier, more intuitive and faster change of blowing mode for the user. Even more preferably, the cam is shaped and configured so that the rotation of the air direction member 18 according to said predetermined angle of rotation is carried out for 50% or less (i.e. for at most 50%, and for example for 30%, 40% or 50% only) of said predetermined angle of rotation, by a movement of the button 32 of the control mechanism under the effect of a thrust exerted on the button 32, then, for the remainder (i.e. 50% or more, for example for 50%, 60% or 70%) of said predetermined angle of rotation, by a movement in the opposite direction of the button 33 under the joint effect of the elastic return member 41 and the cam, when the thrust exerted ceases.

[0078] Such a characteristic can be achieved for example by modulating the profile of the cam path defined by the groove 44 of the grooved drum cam mentioned above, to define at least two consecutive cam path portions, forming ramps of opposite slopes, and the path of which by the follower-forming pin 43 causes the air direction member 18 to rotate according to the predetermined rotation angle in the following manner. First of all, when the user exerts pressure on the button 33 to bring the latter from the released position to the pressed position, the pin 43 travels a first cam path portion by sliding while bearing against one of the side walls of the groove 44 which forms a first ramp, thus causing the rotary coupling part 42 to rotate according to a first rotation angle.Then, when the user stops pushing on the button 33, the elastic return member 41 automatically returns the button 33 to its released position, the pin 43 then traveling a second portion of cam path by sliding, this time bearing against the other of the side walls of the groove 44 which forms a second ramp, with a slope opposite to that of the first ramp, the pin 43 being pressed against the second ramp under the effect of the elastic return member 41, thus forcing a rotation in the same direction of the rotary coupling part 42 according to a second angle of rotation. The slope of the first ramp is chosen to be equal to or greater, more pronounced, than the slope of the second ramp, so that the first angle of rotation is thus less than the second angle of rotation, the sum of the first and second angles of rotation corresponding to the predetermined angle of rotation.Thus, the first rotation angle corresponds to the movement initiated by the user's push, while the second rotation angle corresponds to the automatic complementary movement described previously.

[0079] For example, as in the embodiment illustrated in the figures, the passage of the air direction member 18 from one to the other of the first and second confi air direction configurations is achieved by rotating the air direction member 18 along its rotation axis D-D' by a predetermined rotation angle of 180°. Thus, by rotating 360° along its rotation axis D-D' under the effect of two successive pushes exerted on the button 33, the air direction member 18 can advantageously change its angular configuration twice, alternating between said first and second air direction configurations.The grooved drum cam can then be advantageously shaped and configured so that the rotation of the air direction member 18 according to said predetermined angle of rotation is carried out for 90° (first angle of rotation) only (i.e. 50%) by a pure rectilinear translation movement of the button 33, from its released (stable) position to its depressed (unstable) position, under the effect of a thrust exerted by the user on the button 33, then for the remaining 90° by a pure rectilinear translation movement in the opposite direction of the button 33, from its depressed (unstable) position to its released (stable) position, under the joint effect of the elastic return member 41 and the grooved drum cam, when the thrust exerted by the user ceases.

[0080] Advantageously, the internal channeling device 27 described previously has an upper external surface portion 47, therefore oriented in the direction of the free upper end of the blowing head 10. As illustrated in the figures, said upper external surface portion 47 can thus preferentially form an annular upper wall of the internal channeling device 27. Advantageously, said upper external surface portion 47 defines an upper end of the internal channeling device 27. In return, the internal face 21 of the housing 6A of the blowing head 10 carries a fifth peripheral wall 48.The upper external surface portion 47 is then preferably arranged in contact with the fifth peripheral wall 48, and at least partially overlapping the latter, and this advantageously along the entire length of said fifth peripheral wall 48, to therefore oppose the passage of air from the air flow F from the first portion 10A of the housing 6A through said second portion 10B of the housing 6A at least in a mean direction parallel to said mean direction of entry of the air flow F. This therefore contributes to further reinforcing the aeraulic efficiency and the safety of use of the hairdressing appliance 1, by creating an airtight barrier between the internal channeling device 27 and the control portion 10B of the housing 6A of the blowing head 10.For example, as in the embodiment illustrated in the figures, said fifth peripheral wall is formed in whole or in part by a fifth peripheral tongue (or rib) which projects from said internal face 21. Advantageously, the fifth peripheral tongue 48 is made of one material with one or more cover pieces forming the housing 6A of the blowing head 10. Preferably, the fifth peripheral wall 48 has an annular shape.

[0081] In an advantageously complementary manner, the internal channeling device 27 preferably has a lower external surface portion 49, therefore oriented in the direction of the handle 7 and opposite the aforementioned upper external surface portion 47. As in the embodiment illustrated in the figures, said lower external surface portion 47 can thus form an annular lower wall of said internal channeling device 27. Advantageously, said lower external surface portion 49 defines a lower end of the internal channeling device 27. In return, the internal face of the housing 6A of the blowing head 10 advantageously carries a sixth peripheral wall 50.Said lower external surface portion 49 is then preferably arranged in contact with said sixth peripheral wall 50, and at least partially overlapping the latter, to oppose the passage of air from said air flow F, from said first portion 10A of the housing 6A of the blowing head 10 (aeraulic portion), towards the handle 7 at least in a mean direction parallel to said mean direction of entry of the air flow. Preferably, the sixth peripheral wall 50 has an annular shape. Thus, said lower external surface portion 49 and said sixth peripheral wall 50 cooperate to form an airtight barrier making it possible to limit, if not completely avoid, a risk of air leakage inside the housing 6 of the hairdressing appliance 1 towards the handle 7 of the latter. This therefore contributes to further reinforcing the aeraulic efficiency and the safety of use of the hairdressing appliance 1.

[0082] Preferably, the internal face 21 of the housing 6A of the blowing head 10 carries seventh peripheral walls 51A, 51B, spaced and stepped along said axis B-B' of average extension of the blowing head 10. In return, the aforementioned guide channel 15 ("guide tube") advantageously carries eighth peripheral walls 52A, 52B spaced and stepped along said axis B-B' of average extension of the blowing head 10. As visible in the example in FIGS. 5 to 12 in particular, each of said seventh peripheral walls 51A, 51B is arranged in contact (preferably plane on plane) with one of said corresponding eighth peripheral walls 52A, 52B and at least partially overlapping the surface of the latter, to oppose the passage of air from said air flow F from said first portion (aeraulic portion) of the housing 6A of the blowing head 10 in the direction of the handle 7 in a mean direction parallel to said mean direction of entry of the air flow F.Advantageously, said seventh and eighth peripheral walls 51A, 51B, 52A, 52B are of a design respectively generally similar to those of the first and second peripheral walls 22, 24 described previously. Thus, what has been described previously concerning first and second peripheral walls 22, 24 advantageously applies mutatis mutandis to said . seventh and eighth peripheral walls 51 A, 51B, 52A, 52B.

[0083] As shown in the example in Figures 5 to 12, said seventh and eighth peripheral walls 51A, 51B, 52A, 52B are arranged in a free interior space of the housing 6A of the blowing head 10 formed between the guide channel 15 and the internal face 21 of said housing 6A. In a particularly advantageous manner, as in the embodiment illustrated in the figures, said seventh and eighth peripheral walls 51A, 51B, 52A, 52B are arranged in the immediate vicinity of an upper end zone of the guide channel 15 (delimited by the air outlet end 26 of the latter), at the level of which the air inlet 19 of the air distribution member 18 is connected to the guide channel 15.The seventh and eighth peripheral walls 51A, 51B, 52A, 52B therefore cooperate two by two to form at least one pair of airtight barriers, to prevent air leakage, coming from said “airflow portion” 10A of the housing 6A of the blowing head 10, towards the inside of the handle 7, and in particular between the guide channel 15 and the internal face of said housing 6A. This proves to be particularly useful in the case where, as in the embodiment illustrated in the figures, the air distribution member 18 forms an air direction duct and is mounted to move in rotation inside the housing 6A of the blowing head 10, and relative to the guide channel 15. This thus contributes to further reinforcing the airflow efficiency and the safety of use of the hairdressing appliance 1.In particular, this makes it possible to avoid a leak of hot air between the guide channel 15 and the internal face 21 of said housing 6A towards the inside of the handle 7, which would heat the gripping surface of the handle 7 in an uncomfortable or even dangerous manner. In particular, said seventh and eighth peripheral walls may be respectively formed in whole or in part by seventh and eighth peripheral tongues (or ribs) which extend projecting from said internal face 21, respectively projecting from an external face of the guide channel 15 oriented opposite the internal face 21 of the housing 6A of the blowing head 10.

[0084] In order to further improve the practical and intuitive nature of the hairdressing appliance 1 to use, the first and second air blowing outlets 2, 3 are preferably arranged opposite each other, on either side of a plane PI in which a mean extension direction of the hairdressing appliance 1 (or where appropriate one of the mean extension directions of the latter) 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 air blowing outlets 2, 3. Said average extension direction of the hairdressing appliance 1 thus preferably corresponds to the average extension axis B-B' of the blowing head 10. The air blowing outlets 2, 3 are therefore preferentially arranged opposite each other, on either side on the other side of a plane PI in which the axis B-B' of average extension of the blowing head 10 is inscribed. In this way, the first and second air blowing outlets 2, 3 are thus advantageously not simultaneously visible to the user, when the latter looks straight on at the first air blowing outlet 2, respectively at the second air blowing outlet 3. 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 7 of the hairdressing appliance 1 to orient the corresponding one of the air blowing outlets 2, 3 opposite the hair to be treated, in the preferred case where the blowing head 10 is stationarily connected to the handle 7 and where the air direction member 18 is rotatable relative to the blowing head 10 and to the handle 7.

[0085] Preferably, the hairdressing appliance 1 further comprises an indicator system, comprising a visual selection indicator, to provide the user with visual information as to which of said blowing modes is selected. The implementation of such an indicator system is all the more advantageous in the preferred case, illustrated as an example in the figures, where the button 33 of the control mechanism is a monostable button, i.e. a button occupying a rest position that is always identical, regardless of the operating mode of the appliance 1. As in the embodiment illustrated in the figures, the indicator system may be a mechanical indicator system, i.e. an indicator system whose change of state is controlled purely mechanically to reflect the selected blowing mode.In this respect, the indicator system preferably comprises at least one opening 53A, 53B (through, possibly closed by a transparent element) formed in a face of the button 33 of the control mechanism and an indicator part 54, which is housed at least partially in a free space formed inside the button 33 and which is mounted to move relative to said opening 53A, 53B so as to be visible or not, or to be visible in a different manner (from the outside of the device 1), through said opening 53A, 53B depending on which of the blowing modes is selected. Advantageously, the face of the button 33 in which said opening 53A, 53B is formed is a face which is visible to the user regardless of the blowing mode selected. Even more advantageously, as in the embodiment illustrated in the figures, said face of the button 33 carries the contact portion 34 of the latter mentioned previously.Even more preferably, the indicator system comprises at least two (distinct) openings 53A, 53B provided in said face of the button 33, the indicator part 54 being mounted to move relative to the button 33 so as to be visible or not, or to be visible in a different manner (from the outside of the device 1), alternately through one or the other of the openings 53A, 53B depending on which of said modes. blowing mode that is selected. More generally, the indicator system may advantageously comprise as many openings 53A, 53B as the hairdressing appliance 1 has different blowing modes. The openings 53A, 53B may have an identical shape ([Fig. 19]), or different, distinctive shapes.

[0086] For example, as in the embodiment illustrated in the figures, the indicator part 54 may be mechanically connected to the air direction member 18 via the rotary coupling part 42, and be immobilized in rotation relative to the latter, so that the rotation of the rotary coupling part 35 causes a joint rotation of the indicator part 54. The indicator part 54 may advantageously comprise at least one arm or disc 55, which extends radially relative to an axis of rotation of the indicator part 54, and of which an upper face, oriented towards the face of the button 33 carrying the openings 53A, 53B, of which an area 56 is colored (or otherwise marked). The colored area 56 then forms said visual selection indicator.The rotary coupling part 42 being advantageously immobilized in rotation relative to the air direction member 18, the axis of rotation of the rotary coupling part 42 being coincident with the respective axis D-D' of rotation of the air direction member 18, a rotation of the air direction member 18 of said predetermined angle of rotation thus causes a corresponding rotation of the indicator part 42 of the same predetermined angle of rotation. The openings 53A, 53B are advantageously configured and arranged so that: . - when the air direction member 18 occupies the first air direction configuration, a colored zone 56 of the upper face of the disc 55 of the indicator part 54 is arranged opposite one of the openings 53A, 53B so as to be visible to the user via the latter ([Fig. 19], on the left), then - when the air direction member 18 occupies the second air direction configuration by rotation of said predetermined rotation angle, said colored zone 56 is then arranged opposite the other of the openings 53A, 53B so as to be visible to the user through it ([Fig. 19], right).

[0087] As already mentioned previously, the predetermined rotation angle is 180° in the example illustrated in the figures, and the air direction member 18 advantageously changes its angular configuration twice, alternating between the first and second air direction configurations, when it is rotated 360° about its rotation axis D-D' under the effect of two successive pushes exerted on the button 33. As illustrated in the figures, the openings 53A, 53B are advantageously arranged on either side of the coincident axes of rotation of the air direction member 18, the rotary coupling part 42 and the indicator part 56. The indicator part 54 here comprises a disc 57, which extends radially relative to the axis of rotation of the indicator part 56, and the upper face of which, oriented towards the face of the button 33 carrying the openings 53A, 53B, has a colored zone 56 which occupies half of the upper surface of the disc, for example.

[0088] Obviously, other designs and configurations of the indicator system could alternatively be envisaged. In particular, one could alternatively envisage the implementation of an indicator system comprising a luminous visual selection indicator, and therefore electrically controlled. Furthermore, whereas in the embodiment illustrated in the figures the visual selection indicator is visible from above the blowing head 10 of the hairdressing appliance 1, it may alternatively be advantageously provided that the indicator system comprises a visual selection indicator, luminous or not, which is alternately visible from the side of that of said first and second faces 4, 5 which carries the air blowing outlet 2, 3 corresponding to the selected blowing mode, so as to make the hairdressing appliance 1 even more practical and more intuitive to use.

[0089] It will be noted that the use of the terms "first", "second", "third", "fourth", "fifth", "sixth", "seventh" and "eighth" employed in the foregoing are not intended to introduce any technical limitation, to indicate any degree of order or relative importance, but only to facilitate the understanding of the invention. As such, these terms may be omitted altogether where there is no possible confusion.
