Description

Multi-mode hair styling tool with blow dryer and selected blow dryer mode indicator system TECHNICAL FIELD

[0001] The present invention relates to the general technical field of hairdressing appliances, for example for home 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. PRIOR TECHNIQUE

[0002] In the field of hair styling tools, devices designed to blow air onto the hair using different blowing modes are already available, giving these devices a multifunctional character and allowing for various hair drying and / or styling techniques with a single appliance. For example, there are handheld hair dryers, consisting of a handle and a blower head with an air outlet that directs a forced stream of hot or cold air onto the user's hair. The forced airflow follows a single path within the device until it exits through this air outlet.To modify the airflow pattern of these hair dryers, additional accessories, either detachable or fixed, are generally provided at the air outlet. These accessories typically modify the effective airflow cross-section and / or the direction of the airflow, thus defining a variety of different airflow patterns adapted to specific hair drying and / or styling techniques. While these well-known hair dryers are generally satisfactory, they do have some drawbacks. In particular, switching between airflow patterns requires the user to assemble / disassemble accessories, or to manipulate a pre-mounted accessory at the air outlet. This can sometimes be tedious, which detracts from the ease of use and ergonomics of the device.There is also a significant risk of burns when handling the accessory(ies), as well as a possible risk of loss. accessories, when they are not simply stored out of reach and inaccessible to the user when the latter wishes to use them.

WAYS TO IMPLEMENT THE INVENTION

[0011] The hair styling device 1 according to the invention is a portable hair styling device, designed to be grasped and manipulated by hand. It is a hair styling device 1 preferably intended for use in a domestic setting by a user (male or female) without any particular professional skills in hairstyling, i.e., in terms of drying, styling, or shaping hair. Preferably, the hair styling device 1 is designed so that the user operates it on themselves, i.e., on their own hair. However, it is perfectly conceivable that the hair styling device 1 could be designed for use by the user on the hair of another person. Two non-limiting embodiments of the hair styling device 1 are illustrated by way of example in the aforementioned figures.For the sake of simplicity, elements that are substantially identical between the modes of embodiment are identified with the same references to the drawings.

[0012] According to the invention, the hair styling appliance 1 comprises means for generating an airflow F in at least two different blowing modes. It is therefore advantageously a "multimode" or "multifunctional" appliance, being designed and configured to blow an airflow F towards the user's hair in at least two different blowing modes, which can be alternately selected by the user. By "different blowing modes," we preferably mean blowing modes in which the hair styling appliance 1 blows a different airflow, for example, in its shape, direction, and / or intensity, in order to allow different operations to be performed on the hair, depending on the blowing mode chosen, such as drying the hair or styling it, as will be detailed later.The hair styling device 1 has a first face 2, which has a first air blowing outlet 3 for blowing said air flow F out of the hair styling device 1 in a first of said blowing modes, and a second face 4 having a second air blowing outlet 5 for blowing said air flow F out of the hair styling device 1 in a. The second of said blowing modes. The said first and second air blowing outlets 3, 5 are distinct, preferably separated from each other, and advantageously opposite each other. The first and second faces 2, 4, which bear the said first and second air blowing outlets 3, 5, constitute different, and preferably opposite, faces of the hair styling appliance 1. The first and second air blowing outlets 3, 5 advantageously exist simultaneously (i.e., they are both permanently present on the hair styling appliance 1), and not alternately. Advantageously, the hair styling appliance 1 comprises a housing 6, for example made of plastic, an external face of which defines at least a portion of the said first and second faces 2, 4 of the hair styling appliance 1.

[0013] The first and second blowing modes thus typically correspond to different paths of the airflow F within the hair styling appliance 1. The hair styling appliance 1 is therefore advantageously designed and configured so that the airflow F follows different (aerodynamic) paths within the appliance 1 depending on the blowing mode selected by the user. In other words, the airflow F follows at least one initial path within the hair styling appliance 1 in the first of these blowing modes, until it is blown out of the appliance 1 via the first air outlet 3.In a second of said blowing modes, the air flow F follows another path within the hair styling device 1, that is to say a path which differs at least in part from the path(s) taken by the air flow F in the first of the blowing modes, until it is blown out of the hair styling device 1 by means of the second air blowing outlet 5. The implementation of such different aerodynamic paths advantageously allows the definition of very different blowing modes, depending in particular on the configuration and conformation chosen of the first and second air blowing outlets 3, 5, the relative arrangement of the latter, etc.

[0014] As in the embodiments illustrated in the figures, a first blowing mode can advantageously correspond to an operating mode of the hair styling appliance 1 in "blowing brush" mode, while a second blowing mode can advantageously correspond to an operating mode of the hair styling appliance 1 in "hair dryer" mode. Obviously, the invention is not not limited to such specific blowing modes, and other blowing modes may be considered depending on the intended uses of the hair styling appliance 1 for drying and / or styling hair. Furthermore, the number of different blowing modes is not, in practice, limited to two. Moreover, a single blowing mode may correspond to a plurality of different paths of the airflow F within the hair styling appliance 1.

[0015] As in the embodiments illustrated in the figures, the hair styling appliance 1 preferably includes a handle 7 (or grip) for manual handling, which is intended to be grasped manually by the user to operate the hair styling appliance 1. Advantageously defined by a portion of the housing 6 of the hair styling 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, elongated shape so that it can be grasped fully by an adult user.As illustrated in the figures, the hair styling device 1 further preferably includes a blower head 10 connected to the handle 7 and advantageously carrying said first and second air blower outlets 3, 5, so that the airflow F is advantageously intended to be blown out of the hair styling device 1 towards the user's hair via the blower head 10. Advantageously defined by a portion of the housing 6 of the hair styling device 1, said blower head 10 has at least a first face which defines, or at least contributes to defining, said first face 2 of the hair styling device 1, and a second face which defines, or at least contributes to defining, said second face 4 of the hair styling device 1.Alternatively, however, the blower head 10 could carry one of the first and second air blower outlets 3, 5, while the other of the first and second air blower outlets 3, 5 would be carried by the handle 7, or yet another part of the hair styling device 1. Advantageously, the blower head 10 extends along an axis B-B' of average extension, between a lower end at which the blower 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. As in the embodiments illustrated in the figures, the average extension axis B-B' of the blow-off head 10 is advantageously parallel or collinear (coinciding) with the average longitudinal extension axis A-A' of the handle 7. The hair styling device 1 then extends. advantageously, in general, along an average extension direction, which is parallel or collinear with said axis A-A' of average longitudinal extension of the handle 7 and said axis B-B' of average extension of the blow head 10.

[0016] As in the embodiments illustrated in the figures, the first blow-drying method advantageously corresponding to an operating mode of the hair styling appliance 1 in "blowing brush" mode, the blow-drying head 10 typically includes a mechanical hair engagement element 11, capable of mechanically interacting with the user's hair, particularly for brushing, styling, and / or combing it. Advantageously located on the first face of the blow-drying head 10 (which defines, or helps to define, said first face 2 of the hair styling appliance 1), the mechanical hair engagement element 11 may comprise a plurality of rows or bars of bristles and / or brush bristles.The first air outlet 3 may advantageously comprise one or more air outlet portions, for example defined (or each defined) by a continuous elongated opening such as a slot or by a plurality of distinct orifices arranged in a line (straight or curved). As illustrated in particular in Figures 3 and 10, said first air outlet 3 is advantageously arranged between the bristles and / or brush bristles of the mechanical engagement element 11 of the hair. Respectively, the second blowing mode advantageously corresponding to an operating mode of the hair styling appliance 1 in "hair dryer" mode, the second air outlet 5 may have a generally oblong, elongated opening, as illustrated in particular in Figures 4 and 11, to blow the airflow F in the form of an air blade.Alternatively, the second air blow outlet 5 could have, for example, an opening of generally circular shape to blow the airflow F in a substantially cylindrical or truncated conical shape.

[0017] Advantageously, the means for generating the airflow F include a blower module 12 (or "motor-fan unit") for initiating the airflow F from ambient air in the environment of the hair styling appliance 1. Preferably, the blower module 12 is integrated within the hair styling appliance 1 itself. The hair styling appliance 1 is advantageously provided with an air inlet 13, through which ambient air can be drawn by the blower module 12 in order to be blown towards the the user's hair. The blower module 12, which typically includes at least one fan driven by an electric motor, can advantageously be arranged within the handle 7 or within the blower head 10. More preferably, however, the blower module 12 is assembled to the handle 7 at its second end 9, so that the blower module 12 advantageously extends the handle 7 beyond its second end 9. Advantageously, the blower head 10 is connected to the handle 7 at its first end 8. The hair styling device 1 advantageously includes a guide channel 14 formed inside the handle 7 to guide and channel the airflow F initiated by the blower module 12 to the blower head 10.As in the embodiments illustrated in the figures, the guide channel 14 can advantageously be a single channel, so that it defines a common portion of the different paths taken by the airflow F within the hair styling device 1 according to the different blowing modes. Alternatively, however, several separate guide channels could be implemented, although this would compromise the simplicity of the design and manufacture of the device 1. Advantageously, the means for generating the airflow F according to at least two different blowing modes thus include said guide channel(s) 14.

[0018] The blow-dry head 10 can be designed to be removably connected to the handle 7, allowing the user to separate it from the handle 7, for example, to clean or replace it. Alternatively, as in the embodiments illustrated in the figures, the blow-dry head 10 is designed to remain permanently connected to the handle 7 of the hair styling appliance 1 and is therefore not intended (under normal use) to be detached from the handle 7 by the user. This simplifies both the design and the use of the hair styling appliance 1. In any case, the blow-dry head 10 is preferably permanently connected to the handle 7.

[0019] Preferably, the hair styling unit 1 also includes a heating element designed to raise the temperature of the airflow F initiated by the blower module 12. Integrated within the hair styling unit 1, the heating element is arranged to be interposed in the airflow F initiated by the blower module 12. In the embodiments illustrated in the figures, the heating element (not shown) is advantageously positioned inside the guide channel 14 formed in the handle 7. The heating element is typically an electric heating element, comprising a heating resistor formed of an electrically conductive wire wound around an insulating core. Alternatively, the heating element could be housed in the blower head 10, although this would reduce the compactness of the latter. Advantageously, the hair styling appliance 1 includes means 15 for manual control and / or adjustment by the user of the electrical operation of the hair styling appliance 1, and in particular of the blower module 12 and / or the heating element.These are control means, for example, toggle switches, push-button switches, and / or slide or dial dimmers as illustrated in the figures, which the user can directly operate to electrically switch the hair styling appliance 1 on / off and to change the rotation speed of the blower module's fan 12, and therefore the speed / flow rate F of the air blown by the hair styling appliance 1, and / or the heating temperature of the heating element. Such manual control / adjustment means 15 can be positioned, for example, on the handle 7 as illustrated in the figures, or on the blower module 12 when the latter is assembled to the second end 9 of the handle 7.The hair styling appliance 1 may optionally include a hot / cold air switch (not shown), for example located on the handle 7, to control the switching on and / or off of the heating element. Advantageously designed as a portable power tool, the hair styling appliance 1 is preferably intended to be mains-powered via a power cord 16 fitted at one free end with a plug (not shown).

[0020] Preferably, the means for generating the airflow F include an air direction device 17 (“air distribution device”, or “air deflection device”, or “deflector”) for directing the airflow F initiated by the blower module 12 towards one and / or the other (and preferably one or the other) of the first and second air outlets 3, 5 of the hair styling unit 1, depending on the selected blowing mode. As such, the air direction device 17 is advantageously mounted to move within the hair styling unit 1, at least between a first air direction configuration (or “first air distribution configuration”) in which the air direction device 17 directs the initiated airflow F towards (and preferably only towards) the first air outlet 3 according to said first blowing mode, and a second air direction configuration (or "second air distribution configuration") in which the air direction device 17 directs the initiated airflow F towards (and preferably only towards) the second air blow outlet 5 according to said second blowing mode.

[0021] The air direction element 17 is therefore advantageously designed and configured to define, or at least to help define, different paths of the airflow F within the hair styling appliance 1, depending on its air direction configuration. Preferably, the air direction element 17 is arranged inside the blower head 10, which contributes to a simple and compact design of the latter. The air direction element 17 is then advantageously configured to divert the airflow F exiting the guide channel 14 provided in the sleeve 7 towards one or both of the first and second air blower outlets 3, 5. Even more advantageously, the air direction element 17 is configured to divert the airflow F exiting the guide channel 14 alternately towards one or both of the first and second blower outlets 3, 5.Alternatively, the air steering organ 17 could be arranged inside the control stick 7, although at the expense of the latter's compactness.

[0022] Preferably, the air direction member 17 forms an air direction duct (or "air deflection duct", "deflector duct" or "flush") which extends longitudinally beyond one end of the handle 7, and typically beyond the first end s of the handle 7. The air direction member 17 then includes at least one air direction outlet 18, through which the airflow F is directed by the air direction member 17 towards one and / or the other (and preferably towards one or the other) of the first and second air blow outlets 3, 5 depending on the air direction configuration occupied by the air direction member 17.In the case where the blower module 12 is arranged in the duct 7 or at the second end 9 of the duct 7, as in the embodiments illustrated in the figures, the air direction member 17 may include an air inlet 19, connected to the guide channel 14 of the duct 7 to collect the airflow F initiated by the blower module 12. The air direction member 17 thus advantageously extends the guide channel 14 beyond the first end s of the duct 7. Advantageously, the air direction duct formed by the air direction member 17 comprises a hollow tube of generally cylindrical or preferably frustoconical shape. Open at one of. its ends to define said air inlet 19, the hollow tube then preferentially presents a wall substantially airtight through which said air direction outlet 18 is provided.

[0023] The hair styling device 1 also includes a control system 20 to allow the user to alternately select one or the other of said blowing modes, that is to say, to control the transition of the hair styling device 1 from one of said blowing modes to another of said blowing modes, and for example from said first blowing mode to said second blowing mode (Figures 3 and 4, and 10 and 11) and vice versa from said second blowing mode to said first blowing mode. In this respect, as in the embodiments illustrated in the figures, the control system 20 is advantageously connected to the air direction element 17 to control each transition of said air direction element 17 from one to the other of said first and second air direction configurations mentioned above.

[0024] By operating the control system 20, the user can thus alternately select one or the other of the at least two different blowing modes of the hair styling appliance 1. The user can therefore advantageously choose through which of the first and second air outlets 3, 5 the airflow F will be blown out of the hair styling appliance 1, and thus select the operating mode of the hair styling appliance 1. As in the embodiments illustrated in the figures, the control system 20 is advantageously separate from the manual control and / or adjustment means 15 for the electrical operation of the hair styling appliance 1 and the hot / cold air switch, as described above, which the hair styling appliance 1 may optionally include.It is thus advantageously possible for the user to select one of the blowing modes, even if another blowing mode is already selected, before the blower module 12 of the hair styling appliance 1 is switched on. As illustrated in the figures, the control system 20 is advantageously integrated into the blower head 10 and is preferably positioned on its mid-extension axis B-B'. Preferably, at least a portion of an element of the control system 20 forms, or at least contributes to forming, the upper (free) end of the blower head 10. This allows for easy and intuitive activation of the control system by the user.

[0025] According to the invention, the hair styling appliance 1 further comprises an indicator system for providing visual information to the user as to which of the blow-drying modes is selected via the control system 20. "Visual information" here means an indication that is visually perceptible to the naked eye by the user looking at the hair styling appliance 1 held in one hand. The indicator system includes a visual selection indicator 21, 21', 21" which is alternately visible on the side of the first and second face 2, 4 that bears the (first or second) air blow-drying outlet 3, 5 corresponding to the (first or second) selected blow-drying mode.In other words, the visual selection indicator 21, 21', 21" is designed and configured to be located on, and visible from, the side of the (first or second) face 2, 4 of the hair styling appliance 1 bearing the selected (first or second) air outlet 3, 5, typically when the user's eye is positioned facing and directly opposite the (first or second) face 2, 4 of the hair styling appliance 1 bearing the selected (first or second) air outlet 3, 5. It is therefore understood that the visual selection indicator 21, 21', 21" is only visible from the side of the (first and second) face 2, 4 that bears the air outlet 3, 5 corresponding to the selected airflow mode.

[0026] Thus, in the case where, as illustrated in the figures, the hair styling device 1 comprises only first and second faces 2, 4, each bearing a first and second air blowing outlet 3, 5 respectively, the said visual selection indicator 21, 21', 21” is therefore visible - either on the side of the first face 2 (and not on the side of the second face 4, figure 5 on the left) when the first blowing mode is selected, so as to visually inform the user that the first blowing mode is selected, and therefore that the airflow F will be blown out of the hair styling appliance 1 through the first air blowing outlet 3, - either on the side of the second face 4 (and not on the side of the first face 2, figure 5 on the right) when the second blowing mode is selected, so as to visually inform the user that the second blowing mode is selected, and therefore that the air flow F will be blown out of the hair styling appliance 1 through the second air blowing outlet 5.

[0027] In other words, the visual selection indicator 21, 21', 21" is only visible on the face (first face 2 or second face 4) which has the air blow-out outlet (first air blow-out outlet 3 or second air blow-out outlet 5) which has been previously selected by the user using the control system 20. This allows the user to identify very easily and quickly, and without having to orient the hair styling appliance 1 in a specific way, which air blow-out outlet 3, 5 will be used, and therefore which face 2, 4 of the hair styling appliance 1, he should orient towards his hair.In addition, if the user is unsure which air outlet 3, 5 is selected, he will intuitively tend to look at one of the faces 3, 5 of the hair styling appliance 1, and he will then immediately observe the presence of the visual selection indicator 21, 21', 21" on the face (first face 2 or second face 4) which will be active (i.e. through which the airflow F will be blown out of the hair styling appliance 1).

[0028] The hair styling device 1 according to the invention is thus particularly practical and intuitive to use, even for a user without particular professional skills in hairstyling, insofar as the user can thus choose at will, with the help of the control system 20, a blowing mode from among a plurality of different blowing modes offered by the hair styling device 1, and then be informed in a particularly simple and practical way, by a simple glance at the hair styling device 1, as to which of the blowing modes is actually selected, and therefore as to which of the air blowing outlets 3, 5 through which the flow F of air will be blown out of the hair styling device 1.Thus, after selecting one of the blowing modes by operating the control system 20 (if the desired blowing mode was not already selected), the user can easily ensure that the airflow F is indeed blown out of the styling appliance 1 through the air outlets 3, 5 that they intend to direct towards their hair in order to benefit from the corresponding blowing mode. Furthermore, the safety of using the styling appliance 1 is advantageously increased, since the risk of the user accidentally burning themselves by being surprised by the face 3, 5 from which the hot airflow F is blown is considerably reduced thanks to the presence of the visual selection indicator 21, 21', 21" directly visible on the face 3, 5 corresponding to the selected blowing mode.

[0029] Preferably, as in the embodiments illustrated in the figures, the first and second air outlets 3, 5 are located on the blower head 10 of the hair styling appliance 1, and the visual selection indicator 21, 21', 21" is also located on the blower head 10. Thus, when the first blowing mode is selected, the visual selection indicator 21, 21', 21" is located on, and visible (only) from, the side of the first face of the blower head 10 of the hair styling appliance 1 carrying the first air outlet 3. Conversely, when the second blowing mode is selected, the visual selection indicator 21, 21', 21" is located on, and visible (only) from, the side of the second face of the blower head 10 of the hair styling appliance 1. the hair styling device 1 carrying the second air blowing outlet 5.Advantageously, regardless of the arrangement of the (first and second) air outlets 3, 5, the visual selection indicator 21, 21', 21" is positioned at a distance of between 10 mm and 100 mm, and more advantageously between 20 mm and 50 mm, from the (first or second) air outlet 3, 5 corresponding to the (first or second) selected airflow mode. More specifically, the visual selection indicator 21, 21', 21" is, for example, positioned at a distance of 25 mm from the first air outlet 2 and at a distance of 46 mm from the second air outlet 3. The aforementioned distances advantageously correspond to the shortest distance between the respective proximal edges of each of the elements. Each of these additional technical features contributes to making the 1 hair styling device even more practical and intuitive to use.Furthermore, an arrangement of the visual selection indicator 21, 21', 21" at the level of the blower head 10 of the hair styling appliance 1, and not at the level of the handle 7 of the latter, ensures good visual accessibility of the visual selection indicator 21, 21', 21", without the risk of it being hidden by a hand of the user manipulating the hair styling appliance 1 (and in particular by a hand of the user holding the handle 7 of the latter).

[0030] In order to further improve the practicality and intuitiveness of the hair styling appliance 1, the first and second air outlets 3, 5 are preferably arranged opposite each other, on either side of a plane P1 in which is inscribed a mean extension direction of the hair styling appliance 1 (or, where applicable, one of the mean extension directions of the hair styling appliance 1). In the case where the first and second air outlets The first and second air outlets 3 and 5 are carried by the blower head 10 of the hair styling appliance 1, as in the embodiments illustrated in the figures. The average extension direction of the hair styling appliance 1 preferably corresponds to the average extension direction B-B' of the blower head 10. The first and second air outlets 3 and 5 are thus preferably arranged opposite each other, on either side of a plane P1 in which the average extension direction B-B' is inscribed. In this way, the first and second air outlets 3 and 5 are advantageously not simultaneously visible to the user when the user is looking directly at the first air outlet 3 and, respectively, the second air outlet 5.The user can easily use the hair styling device 1 alternately according to the first blowing mode or according to the second blowing mode by a simple 180° rotation of the handle 7 of the hair styling device 1 to orient the one of the said first and second air blowing outlets 3, 5 corresponding to the hair to be treated.

[0031] Preferably, as illustrated by example in Figures 3 and 10 (left), the first face 2 of the hair styling appliance 1 has a first longitudinal axis of symmetry S1, and the visual selection indicator 21, 21', 21" is advantageously arranged (and visible) aligned along said first longitudinal axis of symmetry S1 when the first blow-drying mode is selected. Preferably, as illustrated by example in Figures 4 and 11 (right), the second face 4 of the hair styling appliance 1 has a second longitudinal axis of symmetry S2, and the visual selection indicator 21, 21', 21" is advantageously arranged (and visible) aligned along said second longitudinal axis of symmetry S2 when the second blow-drying mode is selected.Taken individually or preferably in combination, these additional technical features contribute in particular to giving the hair styling appliance 1 a particularly intuitive, ergonomic, and aesthetic character. Advantageously, as illustrated in the figures, the first and second axes of symmetry S1, S2 are inscribed in a plane orthogonal to the aforementioned plane P1, in which is inscribed a direction of average extension of the hair styling appliance 1. This contributes advantageously to the overall aesthetics of the hair styling appliance, as well as to its good balance in the hand.

[0032] Advantageously, the control system 20 includes a movable manual control element 22, such as a button or dial, to allow the user to operate the control system 20 and thus manually select one or the other of the blow-drying modes. "Movable" is advantageously understood here to mean that the manual control element 22 is capable of moving between at least two advantageously predefined positions and / or spatial orientations (relative to the rest of the hair styling appliance 1), typically by translation, rotation, and / or tilting under the effect of a manual mechanical action exerted upon it by the user. Preferably, as illustrated in the figures, the manual control element 22 is located at the blow-drying head 10, that is, it is supported by (or belongs to) the blow-drying head 10, and not at the handle 7.This helps to limit the risk of unintentional manipulation of the manual control 22 by the hand of the user holding the handle 7. Preferably, the manual control 22 is positioned at such a distance from the handle 7 that it cannot be reached by a finger of the user's hand holding the handle 7. While inaccessible to a finger of the user's hand holding the handle 7, the manual control 22 remains advantageously accessible to a finger of the user's other hand. Even more preferably, as illustrated in the figures, the manual control 22 is positioned substantially along an axis parallel to, or coinciding with, the average extension axis B-B' of the blower head 10, so that it is accessible to the user from above the blower head 10.

[0033] According to an example implementation, the indicator system includes - at least one opening 23A, 23B provided through a portion 24A, 24B of a peripheral wall of the manual control unit 22 (movable), which portion 24A, 24B of the peripheral wall is visible (to the user at least) from outside the hair styling appliance 1, and - a support piece 25 which carries the visual selection indicator 21, and which is housed at least partially in a free space 26 provided inside the manual control member 22 (mobile) so that the visual selection indicator 21 is arranged opposite said opening 23A, 23B according to the selected blowing mode.

[0034] In other words, the manual control unit 22 has, on the one hand, a peripheral wall, at least a portion 24A, 24B of which is arranged to be visible to the user from outside the hair styling appliance 1 and is provided with at least one through opening 23A, 23B, and on the other hand, a free space 26 provided within the manual control unit 22. Said at least one opening 23A, 23B thus leads on the one hand to the outside of the hair styling appliance 1 and on the other hand into said free space 26. The support piece 25, which carries the visual selection indicator 21, is disposed at least partially within said free space 26.

[0035] According to this example of implementation, and as illustrated in Figures 1 to 6, the indicator system includes, more preferably: - a first opening 23A provided through a first portion 24A of said peripheral wall, which first portion 24A is visible from outside the hairdressing appliance 1 on the side of the first face 2 thereof, in particular when the user looks at the first face 2 perpendicularly to it, and - a second opening 23B (distinct from said first opening 23A) provided through a second portion 24B of said peripheral wall, which second portion 24B is visible from outside the hairdressing appliance 1 on the side of the second face 4 of the latter, in particular when the user looks at the second face 4 perpendicularly to the latter.

[0036] In this preferred case (hereinafter referred to as "Example 1"), the support piece 25 is then advantageously mounted movably in the free space 26 provided inside the manual control member 22 between - a first position in which the visual selection indicator 21 is arranged opposite the first opening 23A when the first blowing mode is selected (figure 6), and - a second position, in which the visual selection indicator 21 is arranged opposite the second opening 23B when the second blowing mode is selected (as seen in example in figure 7).

[0037] When the support piece 25 is in the first position, the visual selection indicator 21 is visible to the user through the first opening 23A when the user views the first face 2, advantageously perpendicular to it (as shown in the example in Figure 5 on the left, and in Figure 6). When the support piece 25 is in the second position, the visual selection indicator 21 is then visible to the user through the second opening 23B when the user views the second face 4, advantageously perpendicular to it (as shown in the example in Figure 5 on the right, and in Figure 7).Conversely, in the first position, the visual selection indicator 21 is not positioned opposite the second opening 23B, and is therefore not visible to the user when viewing the second face 4 of the hair styling appliance 1, advantageously at a right angle to it (Figure 5, left, and Figure 6). Conversely, in the second position, the visual selection indicator 21 is not positioned opposite the first opening 23A, and is therefore not visible to the user when viewing the first face 2 of the hair styling appliance 1, advantageously at a right angle to it (Figure 5, right, and Figure 7).

[0038] According to another embodiment (hereinafter, “Example 2”) illustrated in Figures 8 to 17, the indicator system comprises, on the one hand, a first opening 27A formed through a first portion 28A of the (fixed) hood of the hair styling appliance 1, an external face of which defines at least a part of the first face 2 of the hair styling appliance 1, and a second opening 27B formed through a second portion 28B of the (fixed) hood of the hair styling appliance 1, an external face of which defines at least a part of the second face 4 of the hair styling appliance 1. These first and second hood portions 28A, 28B advantageously contribute to forming the housing 6 of the hair styling appliance 1. The indicator system comprises, on the other hand, a support piece 25', 25" which carries the visual selection indicator 21', 21".The said support piece 25', 25" is housed in an internal housing 26', 26" which is defined by (in particular between) the said first and second portions 28A, 28B of hood, and is movably mounted between. - a first position in which the visual selection indicator 21', 21" is arranged opposite said first opening 27A when the first blowing mode is selected, and a second position, in which the visual selection indicator 21', 21" is arranged opposite said second opening 27B when the second blowing mode is selected.

[0039] This Example 2 can be presented in different ways, notably as illustrated in figures 12 and 13 (“Example 2A”) or as illustrated in figures 14 and 15 (“Example 2B”). When the visual selection indicator 21', 21" is in said first position, the visual selection indicator 21', 21" is thus visible to the user, through said first opening 27A provided through said first portion 28A of hood, when the latter looks at the first face 2 of the hair styling appliance 1, advantageously perpendicular to said first face 2. When the visual selection indicator 21', 21" is in said second position, the visual selection indicator 21', 21" is then visible to the user, through the second opening 27B provided through said second portion 28B of hood, when the latter looks at the second face 4 of the hair styling appliance 1, advantageously perpendicular to said second face 4.Conversely, in the first position, the visual selection indicator 21', 21" is not positioned opposite the second opening 27B, and is therefore not visible to the user when viewing the second face 4 of the hair styling appliance 1 (Figures 12 and 14). Conversely, in the second position, the visual selection indicator 21', 21" is not positioned opposite the first opening 27A, and is therefore not visible to the user when viewing the first face 2 of the hair styling appliance 1 (Figures 13 and 15).

[0040] In Examples 1 and 2, the visual selection indicator 21', 21" may advantageously comprise, or be formed by, a colored element, which is then, for example, fixed or affixed to all or part of the support piece 25, 25', 25", or defined by a portion of the support piece 25, 25', 25" itself. As is clear from the above, the indicator system may thus advantageously be a mechanical indicator system, therefore devoid of any electrical or electronic components. Such a mechanical indicator system has the advantage of being able to be easily and safely arranged near area(s) of the hair styling appliance 1 that may reach a high temperature when the hair styling appliance 1 is in operation, particularly due to internal circulation of the airflow F heated by the heating element. Such an indicator system is therefore simple, economical, and reliable. particularly interesting. Alternatively, however, the indicator system could include one or more light sources, such as one or more LEDs, which, when illuminated, form the visual selection indicator. In this case, the indicator system would therefore be an electrically controlled indicator system.

[0041] Advantageously, as illustrated in the figures, the control system 20 of the hair styling appliance 1 is a push-push button control mechanism 29, 29', 29" (or "push-push kinematic control mechanism" or "push-push" button control mechanism), thus controlling each transition of the hair styling appliance 1 from one blowing mode to another. Intended to be operated by the user, for example manually, the control system 20 is therefore designed and configured to transform each push exerted by the user (for example, using a finger of the user) on a button 29, 29', 29" of the control system 20 into a transition of the hair styling appliance 1 from one blowing mode to another blowing mode or, at the very least, from one blowing mode to another blowing mode.The button 29, 29', 29" of the control system 20 then advantageously forms the aforementioned manual control element 22. As in the embodiments illustrated in the figures, the push-push button control mechanism 29, 29', 29" is thus advantageously connected to the air direction element 17 to control each passage of the air direction element 17 from one to the other of the first and second air direction configurations.

[0042] Thanks to such a push-push button control mechanism 29, 29', 29", the use of the hair styling appliance 1 is particularly simple and intuitive, since reproducing a simple pushing action by the user against the button 29, 29', 29" of the control mechanism, each time in the same direction, controls each change of blowing mode of the hair styling appliance 1. Each push exerted by the user on the button 29, 29', 29" of the control mechanism thus controls a cyclical transition of the hair styling appliance 1 from a given initial blowing mode to a subsequent blowing mode, and so on, until it returns to the initial blowing mode after the control mechanism has been successively activated as many times as the hair styling appliance 1. account of different blowing modes. Assuming that the means for generating the air flow F of the hair styling appliance 1 are intended to generate the air flow F according to only two different blowing modes, each push exerted by the user on the button 29, 29', 29" thus controls the alternating passage from a first operating mode of the hair styling appliance 1 (first blowing mode) to a second operating mode of the hair styling appliance 1 (second blowing mode), then from the first operating mode to the second operating mode of the hair styling appliance 1, and so on.

[0043] Advantageously, the push-push button control mechanism 29, 29', 29" is designed and configured to control, purely mechanically, each movement of the hair styling appliance 1 from one blow-drying mode to another. The control mechanism is therefore designed and configured to mechanically convert each push exerted by the user (e.g., with a finger) on a button 29, 29', 29" of the control mechanism into a movement of the hair styling appliance 1 from one blow-drying mode to another, or at the very least, from one blow-drying mode to another. The push-push button control mechanism 29, 29', 29" is thus advantageously free of electrical or electromechanical components, making its design particularly simple, economical, and reliable.As in the embodiments illustrated in the figures, the button 29, 29', 29" of the push-push control mechanism is thus advantageously mechanically connected to the air direction member 17 to mechanically transform each movement of the button 29, 29', 29" of the push-push control mechanism under the effect of a push exerted on the button 29, 29', 29" (by the user) into a movement of the air direction member 17 from one to the other of said first and second air direction configurations. It is therefore advantageously not an electromechanical push-push control mechanism, which would establish an electromechanical link 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 that would be connected to the air steering unit 17.The implementation of such a purely mechanical control mechanism advantageously allows the user to modify the blowing mode of the device. The device 1 can be switched on even when it is not powered (i.e., when the device 1 is switched off or even unplugged). This improves the safety of the device 1, as it reduces the risk of an unexpected burst of air blowing in a direction not anticipated by the user, such as towards their face. The device 1 remains easy to use, as the user can still change the airflow mode while it is operating. Furthermore, using a purely mechanical control for changing the airflow mode, rather than an electromechanical one, tends to improve the reliability of the device 1 and reduce its manufacturing cost.

[0044] In one variant (not shown), the button in the push-push control mechanism is a bistable button. Typically, the control mechanism is then designed and configured so that the button is capable - to move from a first stable position (called the relaxed position) to a second unstable position (called the unstable compressed position) under the effect of an initial push exerted by the user, and - to then automatically return to a third stable position (called the stable pressed position), intermediate between the first stable position and the second unstable position, under the effect of an elastic return mechanism when the first push exerted by the user ceases. The button then remains temporarily locked in the said stable pressed position, corresponding to one of the blowing modes of the hair styling appliance 1.

[0045] Conversely, the control mechanism is then designed and configured so that the button can move from the third stable pressed position to the second unstable pressed position under the effect of a second push exerted by the user, which follows the first push and thus unlocks the button, and then return to the first stable released position, under the effect of an elastic return element, when the second push exerted by the user ceases. For example, such a control mechanism with a bistable push-push button can implement a mechanism, a kinematic, called a "cardioid" mechanism.

[0046] According to a more preferred variant, implemented in the embodiments illustrated in the figures, the button 29, 29', 29" of the push-push control mechanism 29, 29', 29" is a monostable button. The control mechanism is therefore preferably designed and configured so that the button 29, 29', 29" is suitable - to evolve from a first stable position (called the released position, or "unpressed position", or even the "rest position") to a second unstable position (called the pressed position) under the effect of a push exerted by the user (as illustrated for example by the first and second states of figures 3 and 4 (Example I) and figures 10 and 11 (Examples 2A and 2B), and - to then automatically return from the pressed position to the released position when the pressure exerted by the user ceases (as illustrated for example by the third state of figures 3 and 4 (Example 1) and figures 10 and II (Examples 2A and 2B)).

[0047] Accordingly, the control mechanism advantageously includes an elastic return element 30, such as a spring, to automatically return the button 29, 29', 29" to the released position (or stable released position, or unpressed position) when the user ceases to push. This "monostable" variant proves more advantageous than the aforementioned "bistable" variant because, since the button 29, 29', 29" systematically returns to the released position, it remains equally accessible to the user regardless of the selected blowing mode. Furthermore, such a "monostable" variant is simpler to design and more robust in use.

[0048] According to one variant (not shown), the control mechanism can be designed and configured to transform each push by the user on the control mechanism button into a switch of the styling appliance 1 from one blow-drying mode to another. In this case, a single push by the user on the control mechanism button switches the styling appliance 1 from one blow-drying mode to another. Once the styling appliance 1 is in this other blow-drying mode, the user can then stop pushing the button. According to another, more In the preferred configuration, as implemented in the embodiments illustrated in the figures, the push-push button control mechanism 29, 29', 29" is designed and configured to transform each push exerted by the user on the button 29, 29', 29" of the control mechanism into a transition of the hair styling appliance 1 from one blow-drying mode to another, and then to automatically finalize the transition of the hair styling appliance 1 to the other blow-drying mode by the automatic return of the button 29, 29', 29" to its stable released position (unpressed position) when the user's push ceases. In other words, the change of blow-drying mode is initiated only by a press exerted by the user on the button 29, 29', 29", and then automatically completed by the control mechanism.This allows, in particular, an easier, more intuitive and faster change of blowing mode for the user.

[0049] The button 29, 29', 29" of the push-push control mechanism 29, 29', 29" typically has a contact portion 31, 31', 31", or interaction portion, designed to come into direct contact with the user (for example, with the user's finger) when the user pushes against the button 29, 29', 29" to change the blowing mode. The aforementioned peripheral wall of the button 29 then advantageously extends beyond the contact portion 31, typically following a peripheral contour of the latter. According to one variant (not shown), at least the contact portion of the button protrudes from an external surface of the hair styling appliance 1 when no pressure is being applied to the button.The control mechanism is therefore advantageously designed and configured so that at least the contact portion 31, 31', 31" of the button 29, 29', 29" is positioned above the external surface of the hair styling appliance 1 when no pressure is applied to the button 29, 29', 29". This facilitates access to and manipulation of the button 29, 29', 29" by the user. This can also advantageously help to limit the risk of contact between the user and the external surface of the hair styling appliance 1, which could be hot, and thus the risk of burns.According to another variant, implemented in the embodiment illustrated in the figures, the control mechanism is advantageously designed and configured so that the contact portion 31, 31', 31" of the button 29, 29', 29" is arranged flush with, or barely abuts, the external surface (or at the very least, the external geometric envelope) of the housing 6 of the hair styling appliance 1 in the absence of pressure exerted on the button 29, 29', 29". This. This variant offers the particular advantage of giving the hair styling appliance 1 greater compactness and an even more aesthetically pleasing appearance, but also of reducing the risk of damage to the button 29, 29', 29" if the hair styling appliance 1 is dropped or subjected to an impact. In any case, the control mechanism is preferably designed and configured so that the contact portion 31, 31', 31" of the button 29, 29', 29" is arranged below the external surface (or at least the external geometric envelope) of the housing 6 of the hair styling appliance 1 (i.e., so that the button 29, 29', 29" retracts completely inside the hair styling appliance 1) when the button 29, 29', 29" moves to its depressed position under the effect of a push exerted by the user to move the hair styling device 1 from one blowing mode to another.The risk of an unintentional change in the blowing mode by interaction of the button 29, 29', 29" with the user or with a surrounding element is thus advantageously limited.

[0050] Different kinematic arrangements of the air direction element 17 can be considered. In order to simplify the design of the hair styling appliance 1 and improve its compactness, the air direction element 17 is preferably mounted to rotate and pivot about an axis C-C' of rotation between at least the first and second air direction configurations, as illustrated in the embodiments shown in the figures. The push-push control mechanism 29, 29', 29" then controls the transition of the air direction element 17 from one to the other of the first and second air direction configurations by rotating the air direction element 17 through a predetermined angle of rotation about said axis C-C' of rotation.Preferably, the air direction member 17 is mounted to rotate freely relative to the handle 7 of the hair styling device 1, the axis C-C' of rotation of the air direction member 17 being preferably parallel to, or preferably coincident with, the axis A-A' of longitudinal extension of the handle 7.

[0051] Thus, as in the embodiments illustrated in the figures where the air direction member 17 is arranged in the blower head 10, the air direction duct advantageously formed by the air direction member 17 can comprise a hollow tube of generally frustoconical shape (as considered above), the axis of revolution of which is advantageously formed by a longitudinal extension axis of the air direction member 17. The longitudinal extension axis of the air direction member 17 is here advantageously coincides with the average extension axis B-B' of the blower head 10. The respective longitudinal extension axes of the blower head 10 and the air direction member 17 are advantageously collinear with the average longitudinal extension axis A-A' of the handle 7. The air direction duct extends the guide channel 14 formed inside the handle 7, via a large base of the frustoconical tube, at which point the air inlet 19 of the air direction duct is located. The effective cross-sectional area for the airflow F inside the tube thus decreases along the longitudinal extension axis of the air direction duct, moving away from the handle 7. The air direction duct advantageously includes a single air direction outlet 18, which is formed through the lateral wall of the hollow tube.The air direction outlet 18, for example, takes the form of an oblong opening extending longitudinally in a plane that carries the longitudinal axis of the air direction duct. The generally frustoconical shape of the air direction duct tube advantageously homogenizes the profile of the airflow F circulating inside the tube. The air direction outlet 18 is advantageously equipped with airflow straightening fins to optimally guide the airflow F towards the first air supply outlet 3 or the second air supply outlet 5, depending on the selected supply mode.In return, the blower head 10 advantageously includes, in the embodiments illustrated in the figures, a first portion of piping 32A provided for ensuring an aerodynamic connection of the air direction outlet 18 of the air direction member 17 with the first air blower outlet 3 when the air direction member 17 occupies the first air direction configuration, and a second portion of piping 32B provided for ensuring an aerodynamic connection of the air direction outlet 18 of the air direction member 17 with the second air blower outlet 5 when the air direction member 17 occupies the second air direction configuration.As illustrated in the figures, the first and second duct sections 32A, 32B can advantageously be defined by an internal ducting device 33, which thus constitutes a "two-way" internal ducting device (or "two-way distributor"). Housed within the blower head 10, the internal ducting device 33 is advantageously fixedly connected to the handle 7 of the hair styling device 1. Thus, when the air direction element 17 occupies the first air direction configuration (first blowing mode, in particular Figures 6, 12 and 14), the air direction outlet 18 of the air direction element 17 is in aerodynamic communication with the first. portion of duct 32A, and therefore with the first air supply outlet 3. On the other hand, the wall of the tube of the air direction member 17 then closes the second portion of duct 32B of the internal ducting device 33. Conversely, when the air direction member 17 occupies the second air direction configuration (second blowing mode, figures 7, 13 and 15 in particular), the air direction outlet 18 of the air direction member 17 is in aerodynamic communication with the second air supply outlet 5. The wall of the tube of the air direction member 17 then closes the first portion of duct 32A of the internal ducting device 33.

[0052] In order to ensure a mechanical connection, as previously mentioned, between the button 29, 29', 29" of the control mechanism and the air direction member 17, and thus to transmit to the latter the mechanical pushing force exerted by the user on the button 29, 29', 29", the control mechanism preferably comprises a rotating coupling piece 34, forming a cam and mechanically connected to the air direction member 17 on one side, and preferably on the other side to the button 29, 29', 29". The button 29, 29', 29" of the push-push button control mechanism 29, 29', 29" is advantageously secured to at least one pin 35 (or roller) forming a follower which cooperates with the cam so that each push exerted on the button 29, 29', 29" causes the part to rotate. rotary coupling 34 around an axis of rotation and a corresponding rotation of the air direction member 17 around its axis C-C' of rotation.Preferably, as in the embodiments illustrated in the figures, the button 29, 29', 29" of the push-push button control mechanism 29, 29', 29" is mounted in pure rectilinear translation along a translation axis D-D', relative to the rest of the hairdressing appliance 1 and in particular relative to the handle 7 of the latter, between an unpressed position (or released position) and a pressed position as previously mentioned. Thus, the movement of button 29, 29', 29" under the effect of a push exerted by the user is a purely rectilinear translational movement, that is to say, along a straight sliding joint, in the same average direction as the pushing force exerted by the user. The manipulation of button 29, 29', 29" is therefore particularly easy and intuitive for the user, regardless of the position and orientation of button 29, 29', 29" relative to the user operating the hair styling appliance 1.Alternatively, although less advantageous in terms of design simplicity and size, But also in terms of ergonomics, the button could, for example, be mounted for rotation or pivoting, or as a rocker, and be shaped and configured so that the contact portion of the button describes a curvilinear arc under the pressure exerted by the user. Even more preferably, the button 29, 29', 29" is arranged relative to the rotating coupling piece 34 so that the D-D' axis of rectilinear translation of the button 29, 29', 29" coincides with the axis of rotation of the rotating coupling piece 34.Thus, each push exerted by the user on the button 29, 29', 29” results in a rectilinear translational displacement of the button 29, 29', 29” and, preferably directly, a rotation of the rotating coupling piece 34 around the D-D' axis of translation of the button 29, 29', 29”, according to a design that is particularly simple and compact due to the preferential absence of an intercalated piece between the button 29, 29', 29” and the rotating coupling piece 34. Alternatively, the D-D' axis of rectilinear translation of the button could be provided parallel to the axis of rotation of the rotating coupling piece 34 and offset from the latter, or even provided oblique or orthogonal to the axis of rotation of the rotating coupling piece 34, at the expense, however, of the simplicity of design and the compactness of the control mechanism.

[0053] Advantageously, the rotating coupling piece 34 is fixed against rotation relative to the air direction member 17, the axis of rotation of the rotating coupling piece 34 coinciding with the respective C-C' axis of rotation of the air direction member 17. Thus, each movement of the button 29, 29', 29" under the effect of a push exerted by the user causes the rotating coupling piece 34 and the air direction member 17 to rotate simultaneously, by the predetermined angle of rotation, around a common axis of rotation. This contributes to the simplicity and reliability of the design and operation of the hair styling appliance 1. For example, as illustrated in the figures, the rotating coupling piece 34 and the air direction member 17 can be assembled by complementary shapes and secured to each other by screwing (or by clipping / snap-fit ​​or glue).Alternatively, the rotating coupling piece 34 and the air direction member 17 could possibly form together as a monolithic piece.

[0054] Preferably, as in the embodiments illustrated in the figures, the rotating coupling piece 34 more specifically forms a grooved drum cam. The rotating coupling piece 34 thus comprises at least one cylindrical portion of revolution, which is provided with a groove 36 forming a cam track delimited by two opposing lateral walls of the groove 36 and intended to be traversed by the follower pin 35, which is fixed to the button 29, 29', 29”. The pin 35 is thus captive within the groove 36, which helps to ensure a reliable mechanical connection between the button 29, 29', 29” and the rotating coupling piece 34. More preferably, the groove 36 is peripheral, extending around the entire circumference of the cylindrical portion of revolution, and closed upon itself. In this way, the rotation of the rotating coupling piece 34 around its axis of rotation can be in the same direction of rotation each time the blowing mode is changed.

[0055] For example, in the embodiments illustrated in the figures, the button 29, 29', 29" is mounted for pure rectilinear translation along its rectilinear translation axis D-D', which coincides with the rotation axis of the rotating coupling piece 34. Preferably, the rectilinear translation axis D-D' is parallel to or coincides with the average extension axis B-B' of the blower head 10, said average extension axis B-B' being itself advantageously parallel to or coincides with the rotation axis C-C' of the air direction member 17, said rotation axis C-C' being itself advantageously parallel to or coincides with the average longitudinal extension axis A-A' of the handle 7. This advantageously results, particularly when the four aforementioned axes A-A', B-B', C-C', D-D' coincide, in a particularly simple construction and a hair styling device. 1. Particularly compact.The button 29, 29', 29" advantageously comprises a circular cross-sectional lateral skirt portion 37, 37', 37" of revolution about the rectilinear translation axis D-D', arranged parallel to the cylindrical portion of revolution of the rotating coupling piece 34, at least partially overlapping said cylindrical portion. The button 29, 29', 29" is connected not to a single pin 35, but to two follower pins 35, arranged on either side of the rectilinear translation axis D-D', in order to further improve the reliability of the mechanical connection between the button 29, 29', 29" and the rotating coupling piece 34. A free end portion of each pin 35 is housed in the groove 36 of the grooved drum cam formed here by the rotating coupling piece 34.In order to ensure a rotational lock of the button 29, 29', 29" relative to the rest of the hair styling device 1, and in particular relative to the handle 7 of the latter, and to guide the translational movement of the button 29, 29', 29" along the translational axis D-D'. In a straight line, a portion of each of the pins 35 is housed within a respective oblong guide slot 38 formed in a piece fixed relative to the handle 7. To facilitate the assembly of the hair styling device 1, the pins 35 can each be defined by a cylindrical pin press-fitted into an orifice formed through the wall of the side skirt portion 37, 37', 37" of the button 29, 29', 29", once the button 29, 29', 29" is assembled overlapping the cylindrical portion of revolution of the rotating coupling piece 35, so that a portion of the pins defining such a follower pin 35 extends radially inside the button 29, 29', 29". Optionally, as illustrated by example in figures 16 and 17, an opposite portion of the pins may extend radially outside the button 29', 29" and is captured in one of the oblong guide lights 38.A similar configuration (not illustrated) with regard to groove, pins and guide light is advantageously implemented in the embodiment of figures 1 to 7, except that the opposite portion of the pins is then advantageously captured in the portion of side skirt 37.

[0056] Advantageously, the push-push button control mechanism 29, 29', 29" includes a spring return element 30, as previously mentioned, such as a compression spring. The spring return element 30 is configured and arranged to automatically return the button 29, 29', 29" to its stable released position (unpressed position) when the user ceases to push on the button 29, 29', 29". As illustrated in the figures, the compression spring can be arranged between an inner surface of the button 29, 29', 29" and a surface of the rotating coupling piece 34.The cam formed by the rotating coupling piece 34 is preferably shaped and configured so that the rotation of the air direction member 17 according to said predetermined angle of rotation, which allows the passage of the hair styling device 1 from one blowing mode to another by a corresponding passage of the air direction member 17 from one air direction configuration to another, is achieved:. - for only a first part of said predetermined angle of rotation, by a movement of the button 29, 29', 29" of the push-push control mechanism under the effect of a push exerted by the user on the button 29, 29', 29", then, for the remainder of the said predetermined angle of rotation, by an opposite direction movement of the button 29, 29', 29" under the joint effect of the elastic return member 30 and the cam, when the push exerted by the user ceases.

[0057] Thus, the change in blowing mode is initiated only by the user pushing button 29, 29', 29”, as previously mentioned as the preferred option. The change in blowing mode is automatically completed by the control mechanism after the user releases the button 29, 29', 29”. The user therefore advantageously only needs to exert a fraction of the effort required to rotate the air direction element 17 through the predetermined angle to switch it from one of its air direction configurations to the other. As mentioned above, this allows for a particularly easier, more intuitive, and faster change in blowing mode for the user.More preferably, the cam is shaped and configured so that the rotation of the air direction member 17 according to said predetermined angle of rotation is achieved 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 29, 29', 29" of the control mechanism under the effect of a push exerted on the button 29, 29', 29", 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 29, 29', 29" under the combined effect of the elastic return member 30 and the cam, when the push exerted ceases.

[0058] Such a feature can be achieved, for example, by modulating the cam track profile defined by the groove 36 of the grooved drum cam mentioned above, to define at least two consecutive cam track segments, forming ramps of opposite slopes, and whose path by the follower pin 35 causes the air direction member 17 to rotate according to the predetermined angle of rotation as follows. First, when the user presses the button 29, 29', 29" to move it from the released position (not pressed) to the pressed position, the pin 35 travels a first cam track segment by sliding against one of the lateral walls of the groove 36, which forms a first ramp, thus causing the rotating coupling piece 34 to rotate according to a first angle of rotation. Then, when the user stops pushing on the button 29, 29', 29”, the elastic return member 30 automatically returns the button 29, 29', 29” to its released position (unpressed position). The pin 35 then travels a second portion of the cam track, sliding against the other side wall of the groove 36, which forms a second ramp with a slope opposite to that of the first ramp. The pin 35 is held against the second ramp by the elastic return member 30, thus forcing the rotating coupling piece 34 to rotate in the same direction through a second angle of rotation. The slope of the first ramp is chosen to be equal to or greater than the slope of the second ramp, so that the first angle of rotation is less than the second angle of rotation. The sum of the first and second angles of rotation corresponds to the predetermined angle of rotation.Thus, the first angle of rotation corresponds to the movement initiated by push by the user, while the second angle of rotation corresponds to the complementary automatic movement described previously.

[0059] For example, as in the embodiments illustrated in the figures, the transition of the air direction member 17 from one of the first and second air direction configurations to the other is achieved by rotating the air direction member 17 about its axis C-C' of rotation through a predetermined angle of 180°. Thus, by rotating 360° about its axis C-C' of rotation under the effect of two successive pushes exerted on the button 29, 29', 29", the air direction member 17 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 17 through said predetermined angle of rotation is achieved: - for 90° (first angle of rotation) only (i.e., 50%) by a pure rectilinear translational movement of the button 29, 29', 29”, from its released (stable) position to its pressed (unstable) position, under the effect of a push exerted by the user on the button 29, 29', 29”, - then for the remaining 90° by a pure rectilinear translational movement in the opposite direction of the button 29, 29', 29", from its pressed (unstable) position to its released (stable) position, under the joint effect of the elastic return member 30 and the grooved drum cam, when the push exerted by the user ceases.

[0060] Advantageously, as in the embodiments illustrated in the figures and in Examples 1, 2A and 2B, which will be described in more detail below in relation respectively to Figures 6 and 7, 12 and 13, and 14 and 15, the support piece 25, 25', 25" carrying the visual selection indicator 21, 21', 21" is mechanically connected to the air direction member 17 via the rotating coupling piece 34, and is fixed in rotation relative to it, so that the rotation of the rotating coupling piece 34 and of the air direction member 17 causes a joint rotation of the support piece 25, 25', 25" when the air direction member 17 passes from one to the other of said first and second air direction configurations.

[0061] As illustrated by example in figures 6 and 7 (Example 1), the support part 25 may advantageously comprise a tubular part 25A, mounted to slide in rectilinear translation within the rotating coupling part 34, along the axis D-D' of rectilinear translation of the button 29, and an upper part 25B, for example in the form of a hemispherical shell, which extends said tubular part 25A and which is housed in the free space 26 provided inside the button 29 (manual control member 22).

[0062] The upper portion 25B is then advantageously mechanically rotationally connected to the button 29, and has an external face, which is oriented opposite an internal face of the peripheral wall of the button 29 delimiting the free space 26, and which is locally provided with a colored marker forming the visual selection indicator 21. The elastic return element 30, such as for example a compression spring, can advantageously be housed inside the tubular part 25A of the support piece 25 and the rotating coupling piece 34, so as to exert an automatic return force on the button 29 towards its released position (unpressed position) via the support piece 25.

[0063] As mentioned previously, the peripheral wall of the button 29 advantageously has a first opening 23A formed through a first portion 24A of said peripheral wall, which is visible from the outside of the hair styling appliance 1 on the side of its first face 2, and a second opening 23B formed through a second portion 24B of said peripheral wall, which is visible from the outside of the hair styling appliance 1 on the side of its second face 4. Thus, when the first blowing mode is initially selected, for example, the support piece 25 occupies a first position (figure 6) in which the visual selection indicator 21 (colored marker) carried by the upper part 25B of the support piece 25 is arranged opposite the first opening 23A, so that the visual selection indicator 21 is thus visible to the user through said first opening 23A when the user looks at the first face 2 of the hair styling appliance 1, advantageously perpendicular to said first face 2 (figure 5 left, and figure 6).Then, when the user pushes on the button 29 to move it from its released position (not pressed) to its pressed position, and then releases his pushing force, to command a switch from the first blowing mode to the second blowing mode, the support piece 25, the rotating coupling piece 34 and the air direction member 17 rotate together according to the predetermined angle of rotation (for example equal to 180°) along the axis C-C' of rotation of the air direction member 17.The support piece 25 is thus brought to occupy a second position (figure 7) in which the visual selection indicator 21 is this time arranged opposite the second opening 23B, so that the visual selection indicator 21 is then visible to the user through said second opening 23B when the user looks at the second face 4 of the hair styling appliance 1, advantageously perpendicular to said second face 4 (figure 5 on the right, and figure 7).

[0064] Alternatively, as illustrated in Figures 12 and 13 (Example 2A) and Figures 14 and 15 (Example 2B), the support piece 25', 25" may advantageously comprise a tubular portion 25A', 25A", mounted to slide along the linear axis C-C' of the button 29', 29", and an upper portion 25B', 25B", which extends said tubular portion 25A', 25A" and is housed in the free space 26', 26" provided inside the button 29', 29" (manual control element 22). Said upper portion 25B', 25B" is then advantageously mechanically rotationally connected to the button 29', 29".The elastic return element 30, such as for example a compression spring, can advantageously be housed inside the tubular portion 25A', 25A” of the support piece 25', 25” and the rotating coupling piece 34, so as to exert an automatic return force on the button 29', 29” to its released position (unpressed position) via the support piece 25', 25”. The side skirt portion 37', 37” of the button 29', 29” is advantageously provided with a first slot 39A', 39A” and a second slot 39B', 39B”. In these. Examples 2A and 2B, and as mentioned previously, the indicator system advantageously includes a first opening 27A provided through a first portion 28A of the hood of the hair styling appliance 1, and a second opening 27B provided through a second portion 28B of the hood of the hair styling appliance 1. Said first light 39A', 39A” and second light 39B', 39B” of the button 29', 29” are advantageously designed and configured to be arranged respectively opposite the first opening 27A of the first portion 28A of the hood and opposite the second opening 27B of the second portion 28B of the hood.

[0065] As illustrated by example in figures 12 and 13 (Example 2A), the tubular part 25A' of the support piece 25' may advantageously have an external face, which is oriented opposite an internal face of the lateral skirt portion 37' of the button 29', and which is locally provided with a colored marker forming said visual selection indicator 21'.Alternatively, as illustrated by example in Figures 14 and 15 (Example 2B), the upper part 25B” of the support piece 25” may include a pair of curved arms, each having an external face oriented opposite an internal face of the side skirt portion 37” of the button 29”, only the external face of one of said arms being locally provided with a colored marker forming said visual selection indicator 21” (it will be noted here that it is obviously conceivable that the upper part 25B” of the support piece 25” may include only one single curved arm, having an external face locally provided with a colored marker).

[0066] Thus, when the first blowing mode is initially selected, for example, the support piece 25', 25" occupies a first position (Figures 12 and 14) in which the visual selection indicator 21', 21" (colored marker) carried by the tubular part 25A' of the support piece 25' (Figure 12) or by an arm of the upper part 25B" of the support piece 25" (Figure 14), is arranged opposite the first opening 27A provided through the first portion 28A of the hood, so that the visual selection indicator 21', 21" is thus visible to the user through, on the one hand, the said first opening 27A and, on the other hand, the said first light 39A', 39A", when the user looks at the first face 2 of the hair styling appliance 1, advantageously perpendicular to said first face 2 (Figures 12 and 14). 14).

[0067] Then, when the user pushes on the button 29', 29" to move it from its released position (not pressed) to its pressed position, and then releases his pushing force, to command a switch from the first blowing mode to the second blowing mode, the support piece 25', 25", the rotating coupling piece 34 and the air direction member 17 rotate together according to said predetermined angle of rotation (for example equal to 180°) around the axis C-C' of rotation of the air direction member 17.The support piece 25', 25" is thus brought to occupy a second position (figures 13 and 15) in which said visual selection indicator 21', 21" is this time arranged opposite said second opening 27B made through the second portion 28B of hood, so that the visual selection indicator 21', 21" is then visible to the user on the one hand said second opening 27B and on the other hand said second light 39B', 39B" when the user looks at the second face 4 of the hairdressing appliance 1, advantageously perpendicular to said second face 4 (figures 13 and 15).

[0068] In the particular case where the hair styling appliance 1 adopts an indicator system design conforming to Example 1 described above, in combination at least with a control system design in which, as envisaged above, the control system 20 is a push-push button 29 control mechanism whose button 29 is mounted for pure rectilinear translation along a rectilinear axis D-D' between an unpressed position and a pressed position, it is advantageous to provide that, as illustrated by example in Figures 1 to 7, - the peripheral wall of the button 29 forming said manual control element 22 is arranged at least in part within the housing 6 of the hair styling appliance 1 when said button 29 is in the unpressed position, and that - the housing 6 of the hair styling appliance 1 has at least a first notch 40A opposite which said first opening 27A, formed through said first portion 28A of the peripheral wall, is arranged when the button 29 is in the unpressed position (figure 3, right and left), and at least a second notch 40B opposite which said second opening 27B, formed through said second portion 28B of the peripheral wall, is arranged when the button 29 is in the unpressed position (figure 4, right and left).

[0069] In other words, the first face 2 of the hair styling appliance 1 therefore bears the first notch 40A, while the second face 4 of the hair styling appliance 1 bears said second notch 40B. When, as in the embodiment illustrated by example in Figures 1 to 7, the button 29 of the push-push control mechanism and the indicator system are both arranged at the level of (i.e., they are carried by, or belong to) the blower head 10 of the hair styling appliance 1, said first notch 40A is thus advantageously carried by a portion of the housing 6 that defines the first face of the blower head 10. Conversely, the second notch 40B is then advantageously carried by a portion of the housing 6 that defines the second face of the blower head 10.This particular design makes it advantageous to give the hair styling appliance 1 a particularly compact character, by allowing the button 29 to be arranged as much as possible inside the housing 6, while still ensuring good visibility of the visual selection indicator 21.

[0070] Moreover, when the button 29 of the push-push control mechanism is further arranged substantially along an axis parallel to or coinciding with the average extension axis B-B' of the blower head 10, as illustrated in the figures, said first and second notches 40A, 40B advantageously each have an opening oriented towards the upper (free) end of the blower head 10. Said first and second notches 40A, 40B and their respective openings can then advantageously be shaped and dimensioned to allow the insertion of at least one finger of the user into said opening when the user exerts a pushing force against the button 29 to control a change of blowing mode.The user's manipulation of the control system is thus made even easier and more practical, in particular when the contact portion 31 of the button 29 is advantageously arranged flush with, or barely touching, the external surface (or at the very least, the external geometric envelope) of the housing 6 of the hairdressing appliance 1 in the absence of pressure exerted on the button 29. POSSIBILITY OF INDUSTRIAL APPLICATION

[0071] The invention finds its application in the design and manufacture of hairdressing appliances, for example for home use, and more specifically of portable hairdressing appliances designed to blow a flow of air in order to dry and / or facilitate the shaping of hair.
