Multimodal blow-hair shaping device with a blow head and selectively aligned internal air deflectors

Description

[0001] The present invention relates to the general technical field of hairdressing appliances, for example for domestic use, and more specifically to the field of portable 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, devices are already known that are designed to blow a flow of air towards the hair using different blowing modes, in order to give these devices a multifunctional character, for carrying out various hair drying and / or styling techniques using a single device. 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 device, 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, on the part of the user, an operation of assembling / disassembling the accessories, or an operation of handling an accessory pre-assembled at the air outlet. Such an operation can sometimes prove tedious, which is detrimental to the simplicity 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 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 having first and second air blowing outlets distinct from each other, for blowing a flow of air out of the appliance, typically according to different first and second blowing modes.The apparatus in question further comprises means for generating said air flow, typically according to said first and second blowing modes, which include a blower module for initiating said air flow, as well as an air directing member arranged inside the blowing head, the blowing head and the air directing member being mounted 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] Although such a hairdressing appliance has a certain 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 simplicity and 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.

[0005] Document EP3841913 discloses a handheld hairdressing appliance comprising a hand-held gripping handle and a blowing head connected to the handle.

[0006] The objects assigned to the invention therefore aim to propose a new portable multifunctional hairdressing device with a simpler and more efficient aeraulic design.

[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 any particular professional hairdressing skills.

[0011] The objects assigned to the invention are achieved using a portable hairdressing appliance comprising a hand-held grip handle and a blowing head connected to the handle, the blowing head carrying first and second air blowing outlets, distinct from each other, for blowing an air flow out of the appliance, and means for generating said air flow including a blowing module for initiating said air flow and an air directing member comprising an air inlet connected to the blowing module and a single air directing outlet, said air directing member being arranged inside the blowing head, the air directing member and the blowing head being mounted to move relative to each other at least 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 direction configuration in which said air direction member directs the initiated airflow toward the second air blowing outlet, the air direction outlet of the air direction member being provided with a plurality of primary air deflectors, the blowing head comprising first secondary air deflectors for straightening the initiated airflow directed toward the first air blowing outlet from the air direction outlet of the air direction member and second secondary air deflectors for straightening the initiated airflow directed toward the second air blowing outlet from the air direction outlet of the air direction member, a plurality of said primary air deflectors being arranged aligned with a plurality of said first secondary air deflectors when the air direction member is in said first air direction configuration,and a plurality of said primary air deflectors being respectively arranged aligned with a plurality of said second secondary air deflectors when the air directing member is in said second air directing configuration.,

[0013] 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, i.e. 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, i.e. 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.

[0014] The hairdressing appliance 1 comprises means for generating an air flow F which, as will be understood from reading the following, 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, direction and / or 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.

[0015] 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 distinct from each other, preferably distant from each other, preferably opposite each other. As in the embodiment illustrated in the figures, the hairdressing appliance 1 advantageously has a first face 4, which carries said first air blowing outlet 2 and a second face 5 which carries said second air blowing outlet 3. Said 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 (i.e. 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 portion of said 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.

[0016] 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 ( Figure 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 ( figure 8). The implementation of such different airflow 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.

[0017] 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 And 7in particular), while the second blowing mode can advantageously correspond to an operating mode of the hairdressing appliance 1 in “hair dryer” mode ( figures 5 , 8 And 9 in particular). Obviously, the invention is not limited to such particular blowing modes, and other blowing modes may be envisaged 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.

[0018] 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 AA' 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. Advantageously defined by a portion of the housing 6 of the hairdressing appliance 1, 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.Advantageously, the blowing head 10 extends along an axis BB' 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 BB' of average extension may constitute an axis of longitudinal extension of the blowing head 10. As in the embodiment illustrated in the figures, the axis BB' of average extension of the blowing head 10 is advantageously parallel or collinear (merged) with said axis AA' 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 to said axis AA' of average longitudinal extension of the handle 7 and to said axis BB' of average extension of the blowing head 10.

[0019] 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 optimally blown 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 BB' 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 BB' of average extension of the blowing head 10 (. Figure 3 ). Respectively, the second blowing mode advantageously corresponding to an operating mode of the hairdressing appliance 1 in “hair dryer” 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 of the blowing head therefore has an opening of generally oblong, elongated shape, as illustrated in the example in figures 1 , 2 , And 4 à 9, 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 to blow 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 the housing 6. Thus, the second air blowing outlet 3 is advantageously easily identifiable by the user.

[0020] The means for generating the air flow F include a blower module 13 (or “motor-fan unit”) for initiating the air flow F, i.e. for producing the 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 blowing 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 the 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 arranged, formed, 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.

[0021] The blowing head 10 may be designed to be removably connected, assembled, 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.

[0022] Preferably, the hairdressing appliance 1 also comprises a heating element provided to raise the temperature of the air flow F, which is advantageously initiated by the blower module 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 shown) 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 in the example illustrated in the figures, on which the user can directly act in order to electrically activate / deactivate the hairdressing appliance 1 and to modify the rotation speed of the fan of the blower module 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).

[0023] The means for generating the air flow F also include an air direction member 18 (“air distribution member”, or “air deflection member”), for directing, distributing, the air flow F initiated by the blower module 13 towards one and / or the other (and preferably 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. In this respect, the air direction member 18 is arranged inside the blowing head 10, and the blowing head 10 are mounted to move relative to each other at least between a first air direction configuration (or “first air distribution configuration”) in which the air direction member 18 directs the initiated air flow F towards (and preferably only towards) the first air blowing outlet 2, according to the first blowing mode ( figures 3 , 6 And 7in particular), and a second air direction configuration (or “second air distribution configuration”) in which the air direction member 18 directs the initiated air flow F towards (and preferably only towards) the second air blowing outlet 3, reciprocally therefore according to the second blowing mode ( figures 5 , 8 And 9 notably).

[0024] 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 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.

[0025] According to the invention, the air direction member 18 comprises a (single and) unique air direction outlet 19, for directing the air flow F, via said air direction outlet 19, towards the first air blowing outlet 2 when the air direction member 18 is in said first air direction configuration ( figures 3 , 6 And 7 in particular) and vice versa towards the second air blowing outlet 3 when the air direction member 18 is in said second air direction configuration ( figures 5 , 8 And 9in particular). In said first air direction configuration, the air direction outlet 19 of the air direction member 18 is thus in airflow communication with the first air blowing outlet 2, while in said second air direction configuration, said air direction outlet 19 of the air direction member 18 is reciprocally in airflow communication with the second air blowing outlet 3. The air direction member 18 also comprises an air inlet 20, preferably a single one, which is connected to the blower module 13, i.e. which is in airflow communication with the latter, to collect the air flow F initiated by the latter.In the case where the blower module 13 is arranged in the handle 7 or at the second end 9 of the handle 7, as in the embodiment illustrated in the figures, the air inlet 20 of the air direction member 18 is advantageously connected to the guide channel 15 of the handle 7, as mentioned previously, to thus collect the air flow F initiated by the blower module 13. The air direction member 18 then advantageously extends the guide channel 15 beyond the first end 8 of the handle 7.Advantageously, as in the embodiment illustrated in the figures, the air direction outlet 19 is designed and configured so that the air flow F entering through the air inlet 20 exits through the air direction outlet 19 in a mean outlet direction which is intersecting with (or at least arranged in an inclined manner relative to) a mean inlet direction in which the air flow F enters the air direction member 18 through said air inlet 20 (. figures 6 And 8 ).

[0026] According to the invention, the air direction outlet 19 of the air direction member 18 is provided with a plurality of air deflectors, called primary air deflectors 21, for straightening the flow F of air exiting through the air direction outlet 19 from the air inlet 20 of the air direction member 18. In return, the blowing head 10 comprises on the one hand, first outlet air deflectors, called first secondary air deflectors 22, for straightening the initiated air flow directed towards the first air blowing outlet 2 coming from the air direction outlet 19 of the air direction member 18, when the latter is therefore in said first air direction configuration relative to the blowing head 10, and on the other hand, second outlet air deflectors, called second secondary air deflectors 23, for straightening the initiated air flow directed towards the second air blowing outlet 3 coming from the air direction outlet 19 of the air direction member 18, when the latter is therefore in said second air direction configuration relative to the blowing head 10.

[0027] Said primary air deflectors 21, said first secondary air deflectors 22 and said second secondary air deflectors 23 are therefore advantageously intended to orient, to guide, the air flow F towards the first air outlet 2 or towards the second air outlet 3, according to the air direction configuration of the air direction member 18, in a mean direction which is secant, and preferably substantially orthogonal, to said mean direction of entry of the air flow F into the air direction member 18 ( figures 6 And 8). It is understood here that the terms “primary” and “secondary” advantageously refer to the order in which the air deflectors 21, 22, 23 concerned are arranged in consideration of the direction of circulation of the air flow F in the hairdressing appliance 1. Said air flow F therefore first encounters the primary air deflectors 21, before encountering either the first secondary air deflectors 22 or the second secondary air deflectors 23, depending on the air direction configuration of the air direction member 18 relative to the blowing head 10. Typically, the primary air deflectors 21 and the first and second secondary air deflectors 22, 23 form flaps or “blades”, which may each have a substantially planar shape or, as in the embodiment illustrated in the figures, a wavy shape.Arranged so as to be interposed in the air flow F circulating inside the hairdressing appliance 1, each of the primary air deflectors 21 of the air direction member 18 on the one hand, and each of the first secondary air deflectors 22 and each of the second secondary air deflectors 23 of the blowing head 10 on the other hand, advantageously extends from a leading edge to an opposite trailing edge. Advantageously, each of the primary air deflectors 21 on the one hand, and each of the first and second secondary air deflectors 22, 23 on the other hand, extends along a respective median plane Pm1, Pm2, Pm3 of extension. The primary air deflectors 21 are preferably arranged with their median planes of extension arranged parallel to each other. The first secondary air deflectors 22 are preferably arranged with their median extension planes Pm2 arranged parallel to each other.The second secondary air deflectors 23 are preferably arranged with their median extension planes Pm3 arranged parallel to each other.

[0028] The air direction member 18 is thus provided with a number n1 of said primary air deflectors 21, the blowing head 10 comprising in return a number n2 of said first secondary air deflectors 22 and a number n3 of said second secondary air deflectors 23. In practice, the number of primary air deflectors 21, first secondary air deflectors 22 and second secondary air deflectors 23 depends on the sizing of the hairdressing appliance 1. Typically, n1 can be between 3 and 10, n2 can be between 3 and 12 and n3 can be between 3 and 12. For example, as shown in the figures, n1 is equal to 5, n2 is equal to 6 and n3 is equal to 5.

[0029] The hairdressing appliance 1 is further designed and configured so that, as illustrated by example in the figures: a plurality of said primary air deflectors 21 of the air direction outlet 19 of the air direction member 18 is arranged aligned with a plurality of said first secondary air deflectors 22 when the air direction member 18 is in said first air direction configuration ( figures 6 And 7 ), and a plurality of said primary air deflectors 21 of the air direction outlet 19 of the air direction member 18 are respectively arranged aligned with a plurality of said second secondary air deflectors 23 when the air direction member 18 is in said second air direction configuration ( figures 8 And 9 ).

[0030] In other words, in said first air direction configuration, several primary air deflectors 21 are each aligned with one of the corresponding first secondary air deflectors 22, and in said second air direction configuration, several primary air deflectors 21 are each aligned with one of the corresponding second secondary air deflectors 23. Advantageously, when said plurality of primary air deflectors 21 is thus arranged aligned with said plurality of first secondary air deflectors 22 (first air direction configuration / first blowing mode), the trailing edges of said primary air deflectors 21 are then arranged opposite the respective trailing edges of said first secondary air deflectors 22 ( figures 6 And 7). Advantageously, when said plurality of primary air deflectors 21 is reciprocally arranged aligned with said plurality of second secondary air deflectors 23 (second air direction configuration / second blowing mode), the trailing edges of said primary air deflectors 21 are then arranged opposite the respective trailing edges of said first secondary air deflectors 22 ( figures 8 And 9 ). Advantageously, when said plurality of primary air deflectors 21 is thus arranged aligned with said plurality of first secondary air deflectors 22 (first air direction configuration / first blowing mode), the median planes Pm1 of extension of said primary air deflectors 21 are then arranged coplanar with the respective median planes Pm2 of extension of said first secondary air deflectors 22 ( figures 6 And 7). Advantageously, when said plurality of primary air deflectors 21 is reciprocally arranged aligned with said plurality of second secondary air deflectors 23 (second air direction configuration / first blowing mode), the median planes Pm1 of extension of said primary air deflectors 21 are then arranged coplanar with the respective median planes of extension Pm3 of said second secondary air deflectors 23 ( figures 8 And 9 ).

[0031] Thanks to the particular combination of the aforementioned characteristics, the multi-mode blowing hairdressing appliance 1 according to the invention is thus of particularly simple and efficient aeraulic design. The implementation of said primary air deflectors 21, said first secondary air deflectors 22 and second secondary air deflectors 23, and their selective relative alignment as described above makes it possible in particular to optimize, to homogenize, in a particularly efficient manner the blowing of the air flow F out of the hairdressing appliance 1 in the direction of the hair, whatever the air blowing outlet 2, 3 used.It is thus in particular possible, as in the embodiment illustrated in the figures, to obtain a hairdressing appliance 1 of ergonomic use, offering at least first and second different blowing modes in which the air flow F can be blown out of the hairdressing appliance 1 towards the hair in a simple and effective manner respectively according to first and second air blowing directions which are inclined relative to, and in particular orthogonal to, the axis AA' of longitudinal extension of the handle 7 of the hairdressing appliance 1. In addition, the simplicity of the aeraulic design of the hairdressing appliance 1 advantageously makes it easier to manufacture the latter, and further contributes to the robustness and reliability of the latter.

[0032] Advantageously in terms of simplicity of design, as illustrated as an example in the figures, the blowing head 10 is preferably devoid of: of additional air deflectors (flaps or blades) which would be arranged between the primary air deflectors 21 and the first secondary air deflectors 22, respectively between the primary air deflectors 21 and the second secondary air deflectors 23, and / or of additional air deflectors (flaps or blades) which would be arranged between the first secondary air deflectors 22 and the first air blowing outlet 2, respectively between the second secondary air deflectors 23 and the second air blowing outlet 3.

[0033] Preferably, as in the embodiment illustrated in the figures, the primary air deflectors 21 on the one hand, and the first and second secondary air deflectors 22, 23 on the other hand, are fixed. In other words, said primary air deflectors 21 are stationary relative to the air direction outlet 19 of the air direction member 18, the first secondary air deflectors 22 are stationary relative to the first air blowing outlet 2 of the blowing head 10, and the second secondary air deflectors 23 are stationary relative to the second air blowing outlet 3 of the blowing head 10, regardless of the air direction configuration occupied by the air direction member 18. This contributes in particular to the simplified aeraulic design of the hairdressing appliance 1 and to the reliability of the operation of the latter.

[0034] Advantageously in terms of aeraulic efficiency, the hairdressing appliance 1 is designed and configured so that more than half of the primary air deflectors 21 are arranged aligned with more than half of said first secondary air deflectors 22 when the air direction member 18 is in said first air direction configuration. Respectively, the hairdressing appliance 1 is advantageously designed and configured so that more than half of the primary air deflectors 21 are arranged aligned with more than half of said second secondary air deflectors 23 when the air direction member 18 is in said second air direction configuration. Even more advantageously, as in the embodiment illustrated in the figures, the hairdressing appliance 1 is designed and configured so that: in said first air direction configuration, a number at least equal to n1- 1 of primary air deflectors 21 is arranged aligned with a number n2 of first secondary air deflectors 22, while in said second air direction configuration, a number at least equal to n1 - 1 of primary air deflectors 21 is arranged aligned with a number n3 - 1 of second secondary air deflectors 23.

[0035] In order to mechanically reinforce the primary air deflectors 21, the air direction member 18 preferably comprises primary spacers 24, which mechanically connect said primary air deflectors 21 to each other two by two on the one hand, and to a peripheral edge of the air direction outlet 19 on the other hand ( figure 13). Even more preferably, said primary spacers 21 are arranged aligned along at least one line 24A of primary spacers 24, and possibly along two lines 24A, 24B of primary spacers, advantageously parallel to each other, as in the example illustrated in the figures, so as to simplify the design of the air direction member 18 and to limit the disturbance of the passage of the air flow F that could be caused by the presence of said primary spacers 24. Similarly, in order to mechanically reinforce the first secondary air deflectors 22, the blowing head 10 may advantageously comprise first secondary spacers 25, which mechanically connect said first secondary air deflectors 22 together two by two.Preferably, said first secondary spacers 25 are then arranged aligned along at least one line 25A of first secondary spacers 25, and possibly along two lines 25A, 25B of first secondary spacers 25, advantageously parallel to each other, as in the example illustrated in the figures. Conversely, in order to mechanically reinforce the second secondary air deflectors 23, the blowing head 10 may advantageously comprise second secondary spacers, which mechanically connect said second secondary air deflectors 23 to each other. Preferably, said second secondary spacers are then arranged aligned along at least one line of spacers, and possibly along two lines of second secondary spacers.

[0036] Even more preferably, the or each of the line(s) 24A; 24B of primary spacers 24 is arranged aligned, coplanar, in an alignment plane Pa1 with the or one of the line(s) 25A, 25B of corresponding first secondary spacers 25, in said first air direction configuration of the air direction member 18. Conversely, the or each of the line(s) 24A, 24B of primary spacers 24 may advantageously be arranged aligned, coplanar, in an alignment plane with the or one of the line(s) of corresponding second secondary spacers, in said second air direction configuration of the air direction member 18. Such an alignment of the lines of spacers advantageously contributes to limiting the disturbance of the passage of the air flow F that could be caused by the presence of said spacers.Generally speaking, the implementation of such primary spacers 24, first secondary spacers 25, and second secondary spacers, advantageously allows a dimensioning of the air direction outlet 19, the first air blowing outlet 2 and the second air blowing outlet 3 so as to give the latter high useful air passage sections, typically in the preferential ranges mentioned below, while retaining excellent mechanical robustness of the primary air deflectors 21, and of the first and second secondary air deflectors 22, 23.

[0037] In order to ensure optimal blowing of the air flow F towards the hair, in particular in terms of air flow rate, the first air blowing outlet 2 and the second air blowing outlet 3 each have a minimum total useful section which is preferably between 1 cm 2< and 20 cm 2< , and more preferably still between 8 cm 2< and 15 cm 2< . Even more preferably, the first air blowing outlet 2 and the second air blowing outlet 3 have minimum total useful sections of identical values. In return, the air inlet 20 of the air directing member 18 preferably has a useful section (or “air inlet useful section”) between 1 cm 2< and 20 cm 2< , and more preferably still between 8 cm 2< and 15 cm 2< .As for it, the air direction outlet 19 of the air direction member 18 has a useful section (or “useful air outlet section”) which is preferably between 1 cm 2< and 20 cm 2< , and even more preferably between 8 cm 2< and 15 cm 2< .

[0038] Preferably, as mentioned above, the first air blowing outlet 2 extends longitudinally along the axis BB' of average extension of the blowing head 10. Conversely, as also mentioned above, the second air blowing outlet 3 preferably has an air blowing opening, preferably a single one, which extends longitudinally along the axis BB' of average extension of the blowing head 10. This advantageously allows, as such (and therefore independently of the nature of the blowing modes in which the hairdressing appliance 1 is designed to operate), rapid and effective treatment of the hair in a limited number of passes of the hairdressing appliance 1 against said hair.Even more advantageously, in the case where the blowing head 10 has a first face which carries said first air blowing outlet 2 and a mechanical engagement element 11 for the hair, as envisaged in the above and as in the embodiment illustrated in the figures, the first air blowing outlet 2 extends longitudinally along the axis BB' of average extension of the blowing head 10 over a length which is preferably at least equal to half, more preferably at least equal to two-thirds, of a respective length along which the mechanical engagement element 11 for the hair extends respectively longitudinally along the axis BB' of average extension of the blowing head 10.

[0039] In the case in particular of such a configuration of longitudinal extension of the first and second air blowing outlets 2, 3, the air direction member 18 preferably comprises a side wall 26 (airtight), which extends along an axis EE' of longitudinal extension of the air direction member 18 between a first end 27 carrying, defining, the air inlet 20 of the air direction member 18, and a second opposite end 28 closed (and therefore airtight). Advantageously, the air direction outlet 19 of the latter is arranged through the side wall 26 of the air direction member 18 and extends longitudinally along the axis EE' of longitudinal extension of the latter (but not necessarily parallel to said axis EE' of longitudinal extension).Thus, as mentioned previously, the air direction outlet 19 is therefore advantageously designed and configured so that the air flow F entering through the air inlet 20 exits through the air direction outlet 19 in a mean outlet direction which is intersecting with (or at the very least arranged in an inclined manner relative to) a mean inlet direction in which the air flow F enters the air direction member 18 through said air inlet 20 (. figures 6 And 8). As illustrated as an example in the figures, the side wall 26 advantageously defines a hollow internal shape whose section tapers from the first end 27 towards the second end 28 of said side wall 26. Thus, the air direction member 18 therefore advantageously forms an air direction duct, defined by said side wall 26, of generally frustoconical internal shape. In other words, the air direction member 18 advantageously comprises a hollow tube of generally frustoconical internal shape, defined by said side wall 26. Said hollow tube typically has an axis of revolution which is advantageously formed by, or parallel to, the axis EE' of longitudinal extension of the air direction member 18. The axis EE' of longitudinal extension of the air direction member 18 is advantageously coincident with the axis BB' of average extension of the blowing head 10.The respective longitudinal extension axes B-B', EE' of the blowing head 10 and of the air direction member 18 are advantageously collinear with the average longitudinal extension axis AA' of the handle 7. The first end 27 of said side wall 26 therefore defines a large base of the generally truncated internal general shape, via 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 27 towards the second end 28 of the side wall 26, 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 hairdressing appliance 1.

[0040] Even more advantageously, the air direction outlet 19 of the air direction member 18 has a useful section which tapers towards the second end 28 of the side wall 26 of the air direction member 18, as illustrated in the example in FIG. figure 13 in particular. This advantageously contributes to homogenizing the profile of the air flow F leaving the air direction member 18 via said air direction outlet 19, and therefore to further improving the aeraulic performance of the hairdressing appliance 1.

[0041] The blowing head 10 advantageously comprises, as in the embodiment illustrated in the figures, a first portion of pipe 29 provided to ensure airflow communication between the air direction outlet 19 of the air direction member 18 and the first air blowing outlet 2 of the blowing head 10 when the air direction member 18 occupies the first air direction configuration, and a second portion of pipe 30 provided to ensure airflow communication between said air direction outlet 19 and the second air blowing outlet 3 when the air direction member 18 of the blowing head 10 occupies the second air direction configuration.As illustrated in the figures, the blowing head 10 may comprise for this purpose an internal ducting device 31, which at least partly defines said first and second ducting portions 29, 30, and which therefore constitutes a “two-way” internal ducting device (or “two-way distributor”). Said internal ducting device 31 is advantageously fixed, immobile, relative to the first and second air blowing outlets 2, 3 of the blowing head. The air directing member 18 and the internal ducting device 31 of the blowing head 10 are therefore mounted to be movable relative to each other between said first and second air directing configurations. Thus, when the air directing member 18 occupies the first air directing configuration (. figures 3 , 6 And 7in particular), the air direction outlet 19 of the air direction member 18 is in air communication with the first duct portion 29 of the internal duct device 31, and therefore with the first air blowing outlet 2. On the other hand, the air direction member 18 (for example, the side wall 26 of the latter) then closes the second duct portion 30 of the internal duct device 31. Conversely, when the air direction member 18 occupies the second air direction configuration ( figures 5 , 8 And 9 in particular), the air direction outlet 19 of the air direction member 18 is in air communication with the second portion of duct 30, and therefore with the second air blowing outlet 3. The air direction member 18 (for example, the side wall 26 of the latter) then closes the first portion of duct 29 of the internal duct device 31.

[0042] Preferably, the air direction member 18 is arranged at least partly in the internal channeling device 31, as visible as an example in the figures, which contributes to reducing the size of the blowing head 10, and more generally the size of the hairdressing appliance 1. Advantageously, the first and second secondary air deflectors 22, 23 that the blowing head 10 comprises are carried by said internal channeling device 31 ( figures 15 to 17). Advantageously, as in the embodiment illustrated in the figures, the first portion of duct 29 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 30 advantageously has a useful air passage section which decreases continuously in the direction of the second air blowing outlet 3. This advantageously contributes to facilitating the circulation of the air flow F in the direction of the first air blowing air outlet 2 ( figure 18 ), respectively towards the second air blow outlet 3 ( figure 19 ), and thus to reduce the risk of air blocking and increasing the air pressure inside the blowing head 10, as well as the risk of air (possibly hot) leaking into other parts of the blowing head 10.

[0043] 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 movable relative to the blowing head 10 and to the handle 7 between said first and second air direction configurations. In order in particular to simplify the design of the hairdressing appliance 1 and to improve its compactness, the air direction member 18 and the blowing head 10 are preferably mounted movable in rotation, in pivoting, along an axis DD' of rotation, relative to each other between at least said first and second air direction configurations.Preferably, said axis DD' of rotation coincides with (collinear to), or at least parallel to, the axis EE' of longitudinal extension of the air direction member 18, which is itself advantageously coincident with (collinear to) the axis BB' 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 DD' 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 blowing head 10 is connected immobile to the handle 7, and the air direction member 18 is mounted to be able to rotate, along said axis DD' of rotation, relative to the blowing head 10 and the handle 7.In accordance with the foregoing, this second variant proves preferable insofar as it contributes to making the hairdressing appliance 1 simpler to design and use. In this case, the internal channeling device 31 mentioned above is thus itself advantageously connected immobile to the handle 7 of the hairdressing appliance 1, the air direction member 18 being advantageously arranged to be movable in rotation, along said axis DD' of rotation, in said internal channeling device 31 between said first and second air direction configurations.

[0044] In order to further improve the practical and intuitive nature of the hairdressing appliance 1, said first and second air blowing outlets 2, 3 are preferably arranged opposite each other, on either side of a plane P1 in which a mean extension direction of the hairdressing appliance 1 (or where appropriate one of the mean extension directions of the hairdressing appliance 1) is inscribed. Said mean extension direction therefore advantageously corresponds here to a mean extension direction of a portion of the hairdressing appliance 1 which carries said first and second air blowing outlets 2, 3. Said mean extension direction of the hairdressing appliance 1 thus preferably corresponds to the mean extension axis BB' of the blowing head 10.Said first and second air blowing outlets 2, 3 are therefore preferentially arranged opposite each other, on either side of a plane P1 in which said axis BB' of average extension 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, and 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 said first and second air blowing outlets 2, 3 opposite the hair to be treated, in the preferred case where the blowing head 10 is connected immobile to the handle 7 and where the air direction member 18 is mounted mobile in rotation relative to the blowing head 10 and to the handle 7.

[0045] Advantageously, 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 advantageously connected to the air direction member 18 to control each passage of the air direction member 18 from one to the other of said first and second aforementioned air direction configurations.By acting on the control system, the user can thus alternately select one or other of the blowing modes of the hairdressing appliance 1 from among said at least two different blowing modes. The user can thus advantageously choose through which of the first and second air blowing outlets 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 of the cold air / hot air switch, as described previously, that the hairdressing appliance 1 may optionally comprise.It is thus advantageously possible for the user to select one of the blowing modes, while another of the blowing modes is selected, prior to starting the blowing module 13 of the hairdressing appliance 1. The control system is advantageously carried by the blowing head 10, and is preferably positioned along the axis BB' 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 blowing head 10. This allows easy and intuitive activation of the control system by the user.

[0046] Advantageously, the system for controlling the change of blowing mode of the hairdressing appliance 1 comprises a manual control member which is movable, for example a button 32 or a wheel, to allow the user to act on said control system, and thus manually select alternately one or the other of said blowing modes. By "mobile", it is advantageously meant here that the manual control member is able to move between at least two advantageously predefined positions and / or spatial orientations (relative to the rest of the hairdressing appliance 1), typically by translation, rotation and / or even by tilting under the effect of a manual mechanical action exerted against it by the user.Preferably, as illustrated in the example figures, said manual control member is arranged at the level of the blowing head 10, that is to say that it is carried by (or that it belongs to) the blowing head 10, and not at the level of the handle 7. 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 BB' of average extension of the blowing head 10, so that it is therefore accessible to the user from above the blowing head 10.

[0047] Advantageously, as illustrated in the figures, the control system of the hairdressing appliance 1 is a push-push button control mechanism 32 (or “push-push kinematic control mechanism”, or “push-push button control mechanism”). push-push"), to thus control each passage 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 32 of the control system 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 button 32 of the control system then advantageously forms said manual control member mentioned above.As in the embodiment illustrated in the figures, the push-push button control mechanism 32 is thus advantageously connected to the air direction member 18 to control each passage of the air direction member 18 from one to the other of the first and second air direction configurations.

[0048] Thanks to such a push-push button 32 control mechanism, the use of the hairdressing appliance 1 is thus particularly simple and intuitive, since the reproduction of a simple pushing action carried out by the user against the button 32 of the control mechanism, each time in the same pushing direction, controls each change of blowing mode of the hairdressing appliance 1. Each push exerted by the user on the button 32 of the control mechanism thus controls a cyclical passage of the hairdressing appliance 1 from a given initial blowing mode to a following blowing mode, and so on, until returning to said initial blowing mode after the control mechanism has been 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 32 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.

[0049] Advantageously, the push-push button control mechanism 32 is designed and configured to control in a purely mechanical manner each transition 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 32 of the control mechanism 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 push-push button control mechanism 32 is therefore advantageously devoid 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 32 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 32 of the push-push button control mechanism under the effect of a push exerted on the button 32 (by the user) into a movement of the air direction member 18 from one to the other of said 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 (i.e. when the hairdressing appliance 1 is stopped, or even unplugged). The safety of use of the hairdressing appliance 1 is improved, since 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 still 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 use costs.

[0050] 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 (called the released position) to a second unstable position (called the 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 the 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 allows the button to be unlocked, 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".

[0051] According to a more preferred variant, implemented in the embodiment illustrated in the figures, the button 32 of the push-push button control mechanism 32 is a monostable button. The control mechanism is therefore preferably designed and configured so that the button 32 is able to move from a first stable position (called the released position, or “non-pressed position”, or “rest position”) to a second unstable position (called the pressed position) under the effect of a push exerted by the user, and to then automatically return from the pressed position to the released position when the push exerted by the user ceases, under the effect of an elastic return member 33.This "monostable" variant proves to be more advantageous than the aforementioned "bistable" variant insofar as, since the button 32 systematically returns to the released position, it remains just 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.

[0052] Whatever the “bistable” or “monostable” variant envisaged, the push-push button control mechanism 32 therefore advantageously comprises at least one elastic return member 33 to automatically return the button 32 from said pressed position to said released position. Preferably, said elastic return member 33 is a spring, and in particular a tension, compression or flexion spring (leaf spring).

[0053] The button 32 of the push-push button control mechanism 32 typically has a contact portion 34, or interaction portion, intended to come into direct contact with the user (for example with a finger of the latter) when the latter exerts a push against the button 32 to control the change of blowing mode. The contact portion 34 therefore defines an external surface portion of the button 32, oriented towards the outside of the hairdressing appliance 1, and accessible to and visible to the user from outside the hairdressing appliance 1. Advantageously, the contact portion 34 defines a free upper end of the button 32, which is opposite a lower end of the button 32 which is arranged (permanently) inside the hairdressing appliance 1.As in the embodiment illustrated in the figures, the control mechanism is therefore designed and configured so that the contact portion 34 of the button 32 is preferably (entirely) arranged outside the housing 6 of the hairdressing appliance 1, when the button 32 is in the released position. Thus, in the released position and therefore in the absence of pressure exerted on the button 32, the latter advantageously extends projecting from the external surface of the hairdressing appliance 1, typically projecting from the external surface of the housing 6 of the latter. This makes it easier to visually and / or tactilely identify the button 32, to access said button 32 and to manipulate the latter by the user. This can also advantageously contribute to limiting the risk of contact between the user and the external surface of the hairdressing appliance 1, which could possibly be hot, and therefore to limiting the risk of burns.

[0054] In any event, the control mechanism is preferably designed and configured so that the contact portion 34 of the button 32 is arranged below the external surface (or at least, the external geometric envelope) of the housing 6 of the hairdressing appliance 1 (i.e. so that the button 32 retracts, retracts, entirely inside the hairdressing appliance 1) when the button 32 moves towards its depressed position under the effect of a push exerted by the user to switch the hairdressing appliance 1 from one blowing mode to another. The risk of an involuntary change of the blowing mode by interaction of the button 32 with the user or with a surrounding element is thus advantageously limited. As in the embodiment illustrated in the figures, the contact portion 34 of the button 32 is preferably provided with a concave zone, i.e.of an area having a concavity oriented towards the outside of the hairdressing appliance 1. The presence of such a concave area, 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 32, to help keep the finger thus positioned for the effective application of a pushing force against the button 32 to control the change of blowing mode, and this even in particular without visual contact with the button 32.

[0055] 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 push-push button control mechanism 32 is designed and configured to transform each push, exerted by the user, on the button 32 of the control mechanism into a passage, a transition, 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 32 to said stable released position (non-pressed position), when the push 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 32, then automatically completed by the control mechanism.In particular, this allows for easier, more intuitive and faster blowing mode changes for the user.

[0056] 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 DD' of rotation, between at least the first and second air direction configurations, the control system, and for example the push-push button control mechanism 32 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 DD' of rotation. More preferably, the air direction member 18 is mounted to be movable in rotation relative to the handle 7 of the hairdressing appliance 1, the axis DD' of rotation of the air direction member 18 being preferably parallel to, or more preferably merged with, the axis AA' of longitudinal extension of the handle 7.

[0057] In order to ensure a mechanical connection, as mentioned above, between the button 32 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 32, the control mechanism preferably comprises a rotary coupling part 35, 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 32. Said button 32 is advantageously secured to at least one pin 36 (or roller) forming a follower which cooperates with the cam so that each push exerted on the button 32 causes the rotary coupling part 35 to rotate about an axis of rotation and a corresponding rotation of the air direction member 18 about its axis DD' of rotation.Preferably, as in the embodiments illustrated in the figures, the button 32 of the push-push button control mechanism 32 is mounted for rectilinear translation, and more preferably for pure rectilinear translation, in a translation direction CC', relative to the rest of the hairdressing appliance 1, and in particular relative to the handle 7 of the latter, between a non-pressed position (or released position) and a pressed position as mentioned previously. Thus, the movement of the button 32 under the effect of a push exerted by the user is a pure rectilinear translation movement, that is to say according to a rectilinear sliding connection, in the same average direction as the pushing force exerted by the user. The manipulation of the button 32 is thus particularly easy and intuitive for the user, regardless of the position and orientation of the button 32 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 pushing exerted by the user. Even more preferably, the button 32 is arranged relative to the rotary coupling part 35 so that the direction CC' of rectilinear translation of the button 32 coincides with the axis of rotation of the rotary coupling part 35.Thus, each push exerted by the user on the button 32 causes a rectilinear translational movement of the button 32 and, preferably directly, a rotation of the rotary coupling part 35 in the direction CC' of translation of the button 32, according to a design which is particularly simple and compact due to the preferential absence of an intermediate part between the button 32 and the rotary coupling part 35. Alternatively, the direction CC' of rectilinear translation of the button 32 could be provided parallel to the axis of rotation of the rotary coupling part 35 and offset relative to the latter, or even provided oblique or orthogonal to the axis of rotation of the rotary coupling part 35, to the detriment however of the simplicity of design and the compactness of the control mechanism.Advantageously, the rotary coupling part 35 is immobilized in rotation relative to the air direction member 18, the axis of rotation of the rotary coupling part 35 being coincident with the respective axis DD' of rotation of the air direction member 18. Thus, each movement of the button 32 under the effect of a push exerted by the user causes a joint rotation of the rotary coupling part 35 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 35 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 / snapping or gluing.Alternatively, the rotary coupling part 35 and the air direction member 18 could possibly together form a monolithic part.

[0058] Preferably, as in the embodiment illustrated in the figures, the rotary coupling part 35 more specifically forms a grooved drum cam. The rotary coupling part 35 thus comprises at least one cylindrical portion of revolution, which is provided with a groove 37 forming a cam path delimited by two opposite side walls of the groove 37 and intended to be traveled by the pin 36 forming a follower secured to the button 32. The pin 36 is thus captive within the groove 37, which contributes to ensuring a reliable mechanical connection between the button 32 and the rotary coupling part 35. Even more preferably, the groove 37 is peripheral, extending along the entire periphery of the cylindrical portion of revolution, and closed on itself.The rotation of the rotary coupling part 35 along 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.

[0059] For example, in the embodiment illustrated in the figures, the button 32 is mounted in rectilinear translation (pure) its direction CC' of translation (sliding connection), which is coincident with the axis of rotation of the rotary coupling part 35. Preferably, the direction CC' of rectilinear translation is parallel to, or coincident with, the axis BB' of average extension of the blowing head 10, said axis BB' of average extension itself being advantageously parallel to, or coincident with, the axis DD' of rotation of the air direction member 18, said axis DD' of rotation itself being advantageously parallel to, or coincident with, the axis AA' 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', DD' mentioned above are coincident, in a particularly simple construction and a particularly compact hairdressing appliance 1.The button 32 advantageously comprises a portion of lateral skirt 38 of circular section, of revolution in the direction CC' of rectilinear translation, which is arranged parallel to the cylindrical portion of revolution of the rotary coupling part 35, at least partially overlapping said cylindrical portion. The button 32 is connected not to a single pin 36, but to two pins 36 forming followers, arranged on either side of the direction CC' of rectilinear translation, in order to further make the mechanical connection between the button 32 and the rotary coupling part 35 more reliable. A free end portion of each of the pins 36 is housed in the groove 37 of the grooved drum cam formed here by the rotary coupling part 35.In order to ensure rotational locking of the button 32 relative to the rest of the hairdressing appliance 1, and in particular relative to the handle 7 of the latter, and to guide the translational movement of the button 32 in the direction CC' of rectilinear translation, a portion of each of the pins 36 is housed within a respective oblong guide slot 39 formed in a part that is stationary relative to the handle 7 (for example, a part integral with the aforementioned internal channeling device 31).To facilitate assembly of the hairdressing appliance 1, the pins 36 may each be defined by a cylindrical pin force-fitted into an orifice provided through the wall of the side skirt portion 38 of the button 32, once the button 32 is assembled to overlap the cylindrical portion of revolution of the rotary coupling part 35, such that a portion of the pins defining such a follower-forming pin 36 extends radially inside the button 32, while an opposite portion of the pins extends radially outside the button 32 and is captured in one of the oblong guide slots 39.

[0060] Advantageously, the push-push button control mechanism 32 comprises an elastic return member 33, as already mentioned previously, such as for example a compression spring. The elastic return member 33 is configured and arranged to automatically return the button 32 to its stable released position (unpressed position) when the user stops pushing on the button 32. As illustrated in the figures, the compression spring may be arranged between an inner surface of the button 32 and a surface of the rotary coupling part 35.The cam formed by the rotary coupling part 35 is preferably shaped and configured so that the rotation of the air direction member 18 according to said predetermined rotation angle, which allows the hairdressing appliance 1 to switch from one blowing mode to another by a corresponding switch of the air direction member 18 from one air direction configuration to another, is carried out: . for only a first part of said predetermined rotation angle, by a movement of the button 32 of the push-push button control mechanism under the effect of a push exerted, by the user, on the button 32, then, for the remainder of said predetermined rotation angle, by a movement in the opposite direction of the button 32 under the joint effect of the elastic return member 33 and the cam, when the push exerted by the user ceases.

[0061] Thus, the change of blowing mode is only initiated by a push exerted by the user on the button 32, 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 32 of the latter. The user therefore advantageously only needs to provide a portion of the effort necessary to rotate the air direction member 18 according to the predetermined rotation angle to switch 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 32 under the joint effect of the elastic return member 33 and the cam, when the thrust exerted ceases.

[0062] Such a feature can be achieved for example by modulating the profile of the cam path defined by the groove 37 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 36 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 32 to bring the latter from the released position to the pressed position, the pin 36 travels a first cam path portion by sliding while bearing against one of the side walls of the groove 37 which forms a first ramp, thus causing the rotary coupling part 35 to rotate according to a first rotation angle.Then, when the user stops pushing the button 32, the elastic return member 33 automatically returns the button 32 to its released position (unpressed position), the pin 36 then traveling a second portion of cam path by sliding, this time bearing against the other of the side walls of the groove 37 which forms a second ramp, with a slope opposite to that of the first ramp, the pin 36 being pressed against the second ramp under the effect of the elastic return member 33, thus forcing a rotation in the same direction of the rotary coupling part 35 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 pushing by the user, while the second rotation angle corresponds to the automatic complementary movement described previously.

[0063] 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 air direction configurations is carried out by rotating the air direction member 18 about its axis DD' of rotation by a predetermined rotation angle of 180°. Thus, by rotating 360° about its axis DD' of rotation under the effect of two successive pushes exerted on the button 32, 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 translational movement of the button 32, from its released (stable) position to its depressed (unstable) position, under the effect of a thrust exerted by the user on the button 32, then for the remaining 90° by a pure rectilinear translational movement in the opposite direction of the button 32, from its depressed (unstable) position to its released (stable) position, under the joint effect of the elastic return member 33 and the grooved drum cam, when the thrust exerted by the user ceases.

[0064] 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 32 of the control mechanism is a monostable button, that is to say a button occupying a rest position which is always identical, whatever the operating mode of the appliance 1. As in the embodiment illustrated in the figures, the indicator system may be a mechanical indicator system, that is to say 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 40A (through, possibly closed by a transparent element) formed in a face of the button 32 of the control mechanism and an indicator part 41, which is housed at least partially in a free space formed inside the button 32 and which is mounted to move relative to said opening 40A 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 40A depending on which of the blowing modes is selected. Advantageously, the face of the button 32 in which said opening 40A 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 32 carries the contact portion 34 of the latter mentioned previously.Even more preferably, the indicator system comprises at least two (distinct) openings 40A, 40B formed in said face of the button 32, the indicator part 41 being mounted to move relative to the button 32 so as to be visible or not, or to be visible in a different manner (from the outside of the appliance 1), alternately through one or the other of the openings 40A, 40B depending on which of said blowing modes is selected. More generally, the indicator system may advantageously comprise as many openings 40A, 40B as the hairdressing appliance 1 has different blowing modes. The openings 40A, 40B may have an identical shape (. figure 22 ), or different, distinctive shapes.

[0065] For example, as in the embodiment illustrated in the figures, the indicator part 41 may be mechanically connected to the air direction member 18 via the rotary coupling part 35, and be immobilized in rotation relative thereto, so that the rotation of the rotary coupling part 35 causes a joint rotation of the indicator part 41. The indicator part 41 may advantageously comprise at least one arm or disc 42, which extends radially relative to an axis of rotation of the indicator part 41, and of which an upper face, oriented towards the face of the button 32 carrying the openings 40A, 40B, of which an area 43 is colored (or otherwise marked) ( figure 22). Said colored area 43 then forms said visual selection indicator. The rotary coupling part 35 being advantageously immobilized in rotation relative to the air direction member 18, the axis of rotation of the rotary coupling part 35 being coincident with the respective axis DD' 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 41 of the same predetermined angle of rotation. The openings 40A, 40B are advantageously configured and arranged so that: when the air direction member 18 occupies the first air direction configuration, a colored area 43 of the upper face of the disc 42 of the indicator part 41 is arranged opposite one of the openings 40A, 40B so as to be visible to the user through it ( figure 22, left), then when the air direction member 18 occupies the second air direction configuration by rotation of said predetermined rotation angle, said colored zone 43 is then arranged opposite the other of the openings 40A, 40B so as to be visible to the user through it ( figure 22 , right).

[0066] 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 DD' under the effect of two successive thrusts exerted on the button 32. As illustrated in the figures, the openings 40A, 40B are advantageously arranged on either side of the coincident rotation axes of the air direction member 18, the rotary coupling part 35 and the indicator part 41. The indicator part 41 here comprises a disc 42, which extends radially relative to the rotation axis of the indicator part 41, and the upper face of which, oriented towards the face of the button 32 carrying the openings 40A, 40B, has a colored area 43 which occupies half of the upper surface of the disc, for example.

[0067] 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.
