Description

Technical Field

[0001] The present invention relates to the general technical field of hair care appliances, such as household hair care appliances, and more particularly to the field of portable hair care appliances designed to blow an air flow for drying hair and / or facilitating hair styling. Background Art

[0002] In the field of hair care appliances, there are known appliances that are designed to blow an air flow towards the hair according to different blowing modes, so as to endow these appliances with multifunctional features, thereby enabling various hair drying and / or styling techniques to be achieved using a single appliance. For example, there is thus known a hand-held hair dryer that includes a handle and a blow head, the blow head including an air outlet for directing a forced air flow of hot air or cold air towards the user's hair. The forced air flow flows along a single trajectory within the appliance until it exits from the said air outlet. In order to change the blowing mode of these hair dryers, additional accessories are typically provided at the air outlet in a removable or non-removable manner, so as to typically change the effective air passage cross-section and / or the air blowing direction, thereby defining a plurality of different blowing modes suitable for implementing specific hair drying and / or styling techniques. Although these known hair dryers are generally satisfactory, they do have certain drawbacks. In particular, switching the hair dryer from one blowing mode to another requires the user to assemble / dismantle the accessories, or requires manipulating the operation of the accessories pre-installed at the air outlet. This operation has proven to be sometimes tedious, which is not conducive to the ease of use and ergonomics of the appliance. In addition, when manipulating the one or more accessories, there is a non-negligible risk of scalding, and there may also be a risk of losing the accessories when these accessories are not simply stored out of reach and when the user wants to use them but cannot get them. Summary of the Invention

[0003] Therefore, an object assigned to the present invention is to provide a new type of multifunctional portable hair care appliance that is particularly practical and intuitive to use, even for users lacking professional hair styling skills.

[0004] Another object of the present invention is to provide a new type of portable hair care appliance that is ergonomically designed and particularly practical to use.

[0005] Another object of the present invention is to provide a new type of portable hair care appliance that is particularly safe to use.

[0006] Another object of the present invention is to provide a new type of portable hair care appliance with a particularly simple and compact construction.

[0007] Another object of the present invention is to provide a new type of portable hair care appliance that is particularly robust and reliable.

[0008] Another object of the present invention is to provide a novel portable hair care appliance which allows a user to perform a variety of discrete operations easily and efficiently without relying on external auxiliary hair care appliances.

[0009] The object assigned to the present invention is achieved by a portable hair care appliance which comprises an air flow generating member for generating an air flow according to at least two different blowing modes. The appliance has a first face and a second face. The first face bears a first blowing outlet for blowing the air flow out of the appliance in a first blowing mode among the blowing modes, and the second face bears a second blowing outlet for blowing the air flow out of the appliance in a second blowing mode among the blowing modes. The appliance comprises a control system for allowing the user to alternately select one or the other of the blowing modes, and an indicator system for providing the user with visual information about which one of the blowing modes has thus been selected. The indicator system comprises a luminous visual selection marker which is alternately visible on the side of that one of the first and second faces which bears the blowing outlet corresponding to the selected blowing mode.

[0029] The hair care appliance 1 according to the present invention is a portable hair care appliance designed to be picked up and manipulated by hand. It is a hair care appliance preferably intended for use by a user (male or female) lacking any specific hair care professional skills (i.e., in hair drying and styling, or even in hair setting) in a home environment. Preferably, the hair care appliance 1 is designed for the user to use the hair care appliance 1 on themselves, i.e., on their own hair. However, it is entirely conceivable that the hair care appliance 1 is designed to be used by the user on the hair of a third person. In the above figures, different non-limiting embodiments of the hair care appliance 1 are illustrated by way of example. For the sake of simplicity, elements that are substantially the same between the embodiments are denoted by the same reference numerals.

[0030] According to the present invention, the hair care appliance 1 includes an air flow generating member for generating an air flow F according to at least two different blowing modes (i.e., at least a first blowing mode and a second blowing mode, the second blowing mode thus being different from the first blowing mode). Thus, it is advantageously a "multi-mode" or "multi-functional" appliance, designed and configured to blow the air flow F towards the hair according to at least two different blowing modes, which two different blowing modes can be alternately selected by the user. "Different blowing modes" preferably refer to those blowing modes according to which the hair care appliance 1 blows different air flows, for example air flows different in their shape, direction, and / or intensity, in order to perform different operations on the hair according to the selected blowing mode, such as for example a hair drying operation or a hair setting operation.

[0031] The hair care appliance 1 includes at least a first blowing outlet 2 for blowing the air flow F out of the hair care appliance 1 in a first blowing mode among the blowing modes, and a second blowing outlet 3 for blowing the air flow F out of the hair care appliance 1 in a second blowing mode among the blowing modes. The first and second blowing outlets 2, 3 are separate from each other, preferably spaced apart from each other, and preferably opposite to each other. The hair care appliance 1 has a first face 4 carrying the first blowing outlet 2 and a second face 5 carrying the second blowing outlet 3. The first and second faces 4, 5 constitute different, preferably opposite faces of the hair care appliance 1.

[0032] Advantageously, the first and second blowing outlets 2, 3 are present simultaneously (i.e., they are both permanently present on the hair care appliance 1), rather than alternately. Generally, the hair care appliance 1 includes a housing 6 made of, for example, plastic, and the outer faces of the housing 6 define at least a part of the first and second faces 4, 5 of the hair care appliance 1. The housing 6 has an outer surface (defined by the outer faces), which outer surface defines at least a part of the outer surface of the hair care appliance 1.

[0033] Preferably, the blowing mode corresponds to different trajectories of the air flow F inside the hair styling appliance 1. Thus, the hair styling appliance 1 is preferably designed and configured such that the air flow F flows along different (aerodynamic) trajectories inside the hair styling appliance 1 according to the blowing mode selected by the user. In this way, in the first blowing mode, the air flow F thus advantageously flows at least along a first trajectory inside the hair styling appliance 1 until it is blown out of the hair styling appliance 1 through the first blowing outlet 2 ( Figure 5 , Figure 11 , Figure 13 and Figure 15 ). In the second blowing mode, the air flow F advantageously flows along another trajectory inside the hair styling appliance 1 (i.e., a trajectory that is at least partially different from one or more of the trajectories taken by the air flow F in the first blowing mode) until it is blown out of the hair styling appliance 1 through the second blowing outlet 3 ( Figure 6 , Figure 12 , Figure 14 and Figure 16 ). The implementation of such different aerodynamic trajectories advantageously allows for the definition of very different blowing modes, especially depending on the selected configuration and construction of the first and second blowing outlets 2, 3 and their relative arrangement, etc. In particular, this allows for the provision of some blowing modes according to which the air flow F is blown out of the hair styling appliance 1 in different, possibly opposite directions and, for example, through blowing outlets 2, 3 that are spaced apart from each other.

[0034] As shown in the illustrated embodiment, the first blowing mode can advantageously correspond to the operating mode of the hair styling appliance 1 in the "blow - brush" mode (especially Figure 5 , Figure 11 , Figure 13 and Figure 15 ), while the second blowing mode can advantageously correspond to the operating mode of the hair styling appliance 1 in the "hair dryer" mode (especially Figure 6 , Figure 12 , Figure 14 and Figure 16 ). Of course, the present invention is not limited to these specific blowing modes, and other blowing modes can be envisaged depending on the intended use of the hair styling appliance 1 in hair drying and / or styling. In addition, the number of different blowing modes is not actually limited to two. Moreover, a given blowing mode may correspond to multiple different trajectories of the air flow F inside the hair styling appliance 1.

[0035] As shown in the illustrated embodiment, the first blowing mode can thus advantageously correspond to the operating mode of the hair care appliance 1 in the "blow - brush" mode, while the second blowing mode can advantageously correspond to the operating mode of the hair care appliance 1 in the "hair dryer" mode. Of course, the present invention is not limited to these specific blowing modes, and other blowing modes can be envisaged according to the intended use of the hair care appliance 1 in hair drying and / or styling. In addition, the number of different blowing modes is not actually limited to two. Moreover, a given same blowing mode may correspond to multiple different trajectories of the air flow F inside the hair care appliance 1.

[0036] The hair care appliance 1 preferably includes a hand - held handle 7 (or grip), which is intended to be manually grasped by the user to manipulate the hair care appliance 1. The handle 7 is advantageously defined by a part of the housing 6 of the hair care appliance 1. The handle 7 generally extends between a first end 8 and an opposite second end 9, preferably longitudinally along an average extension axis A - A'. The handle 7 advantageously has an elongated shape such that an adult user can hold it with the whole hand. As shown, the hair care appliance 1 also preferably includes a blow head 10 for blowing the air flow F out of the hair care appliance 1 towards the hair. The blow head 10 is connected to the handle 7. The blow head 10 thus advantageously bears first and second blowing outlets 2, 3 such that the air flow F is thus advantageously intended to be blown out of the hair care appliance 1 towards the hair via the blow head 10. The blow head 10 is advantageously defined by a part of the housing 6 of the hair care appliance 1. The blow head 10 has at least a first face and a second face. The first face defines or at least contributes to defining the first face 4 of the hair care appliance 1, and the second face defines or at least contributes to defining the second face 5 of the hair care appliance 1. However, alternatively, the blow head 10 can bear one of the first and second blowing outlets 2, 3, while the other of the first and second blowing outlets 2, 3 will be borne by the handle 7 or another part of the hair care appliance 1. Advantageously, the blow head 10 extends between a lower end (where the blow head 10 is connected to the handle 7) and an opposite (free) upper end along an average extension axis B - B', and thus preferably extends the handle 7 beyond the first end 8 of the handle. As shown in the illustrated embodiment, the average extension axis B - B' of the blow head 10 is advantageously parallel or collinear (coincident) with the average longitudinal extension axis A - A' of the handle 7. The hair care appliance 1 thus advantageously extends generally along an average extension direction that is parallel or collinear with the average longitudinal extension axis A - A' of the handle 7 and the average extension axis B - B' of the blow head 10.

[0037] As shown in the illustrated embodiment, the first blowing mode advantageously corresponds to the operating mode of the hair care appliance 1 in the "blow-dry brush" mode. The blow head 10 generally includes a hair mechanical engagement element 11 that can mechanically interact with the user's hair, thereby in particular brushing, styling, and / or combing the hair. Advantageously, the hair mechanical engagement element 11 is carried by the first face of the blow head 10 (which defines or contributes to defining the first face 4 of the hair care appliance 1). The hair mechanical engagement element 11 may include multiple rows or strips of bristles and / or teeth. The first blowing outlet 2 may advantageously include one or more blowing outlet portions, for example defined (or each portion is defined thereby) by a continuous elongated opening (such as a slot) or by a plurality of discrete holes arranged in a line (straight or curved), as shown in the example illustrated in the figure. In particular, for example, it can be seen from Figure 3 and Figure 9 that the first blowing outlet 2 is advantageously arranged between the bristles and / or teeth of the hair mechanical engagement element 11. Separately, the second blowing mode advantageously corresponds to the operating mode of the hair care appliance 1 in the "hair dryer" mode. The second blowing outlet 3 may have an elongated opening that is generally oval, particularly as Figure 4 and Figure 10 illustrated by way of example, to blow the air flow F in the form of a blowing vane. Alternatively, the second blowing outlet 3 may have an opening that is generally circular, for example, to blow the air flow F in a generally cylindrical or frustoconical form. For example, the second blowing outlet 3 may be defined by a nozzle 12, for example a fixed (non-removable) or, conversely, a detachable (removable) nozzle, at least a portion of which extends and protrudes from the surface of the second face 5 of the hair care appliance 1, generally from the outer surface of the housing 6. Thus, the user can advantageously and easily identify the second blowing outlet 3.

[0038] Advantageously, the air flow generating means for generating the air flow F comprises a blower module 13 (or "motor fan unit") for starting the air flow F from the ambient air of the environment of the hairdressing appliance 1, i.e. generating the air flow F. Preferably, the blower module 13 is embedded inside 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 to be blown towards the hair. The blower module 13, which generally comprises at least one fan actuated by an electric motor, can advantageously be arranged inside the blower head 10 or inside the handle 7, or assembled to the handle 7 at its second end 9. More preferably, however, the blower module 13 is assembled to the handle 7 at its second end 9, so that the blower module 13 advantageously extends the handle 7 beyond said second end 9 of the handle. Advantageously, the blower head 10 is then connected to the handle 7 at its first end 8. In the case where the blower module 13 is thus arranged inside the handle 7 or more preferably assembled to the handle 7 at the second end 9 of the handle 7, the hairdressing appliance 1 advantageously comprises a guide channel 15 arranged, formed inside the handle 7, for directing and guiding the airflow F activated by the blower module 13 to the blowing head 10. As shown in the illustrated embodiment, the guide channel 15 can advantageously be single, so that it defines a common part of the different trajectories taken by the airflow F inside the hairdressing appliance 1 according to different blowing modes. However, alternatively, a plurality of discrete guide channels can be implemented, although at the expense of simplicity of design and manufacture of the appliance 1. Advantageously, the airflow generating member for generating the airflow F according to at least two different blowing modes thus comprises said guide channel 15 (or said plurality of guide channels).

[0039] The blow head 10 may be designed to be removably connected, assembled to the handle 7, so that the user can separate the blow head 10 from the handle 7, for example, to clean or replace the blow head 10. Alternatively, as shown in the illustrated embodiment, the blow head 10 is designed to remain permanently connected to the handle 7 of the hairdressing appliance 1, and is therefore not intended to be separated from the handle 7 by the user (in normal use). This simplifies the design and use of the hairdressing appliance 1. In any case, the blow head 10 is preferably connected immovably relative to the handle 7.

[0040] Preferably, the hairdressing appliance 1 further comprises a heating element designed to increase the temperature of the air flow F advantageously activated by the blower module 13. The heating element, which is usually embedded in the interior of the hairdressing appliance 1, is advantageously arranged to be inserted into the air flow F activated by the blower module 13. As shown in the illustrated embodiment, the heating element is advantageously located inside a guide channel 15 at least partially arranged in the handle 7 ( Figure 5 , Figure 6 and Figures 11 to 16)。The heating element is typically an electric heating element, including an electric heating resistor formed by an electric wire (not shown) wound around an insulating core 16. Alternatively, the heating element can be housed in the blow head 10, although at the expense of the compactness of the blow head 10. Advantageously, the hair care appliance 1 includes a manual control and / or adjustment member 17 for manually controlling and / or adjusting the electrical operation of the hair care appliance 1, in particular the blower module 13 and / or the heating element. This is an adjustment member such as a toggle switch, a button and / or a slide or rotary converter type in the example shown in the drawings, on which the user can directly act to electrically start / stop the hair care appliance 1 and change the rotational speed of the fan of the blower module 13, and thus change the speed / flow rate of the air flow F blown by the hair care appliance 1, and / or the heating temperature of the heating element. The manual control / adjustment member 17 can be located, for example, at the handle 7, or at the blower module 13 when the blower module 13 is assembled to the second end 9 of the handle 7 as shown in the illustrated example. The hair care appliance 1 can also optionally include a cold / hot air switch, for example arranged at the handle 7, preferably at its first end 8, to control the opening and / or closing of the heating element. The hair care appliance 1 advantageously constitutes a portable electronic appliance, and the hair care appliance 1 is preferably designed to be powered from a power source via a power cord, which is fitted with an electrical connection plug (not shown) at its free end.

[0041] Preferably, the air flow generating member for generating the air flow F includes an air guiding member 18 (or "air distribution member", or "air deflection member") for guiding and distributing the air flow F initiated by the blower module 13 to one and / or the other (preferably to one or the other) of the first and second blowing outlets 2, 3 of the hair care appliance 1 according to the selected blowing mode. For this purpose, the air guiding member 18 is advantageously mounted so as to be movable inside the hair care appliance 1 at least between a first air guiding configuration (or "first air distribution configuration") and a second air guiding configuration (or "second air distribution configuration"), in the first air guiding configuration, the air guiding member 18 guides the initiated air flow F to (and preferably only to) the first blowing outlet 2 according to the first blowing mode among the blowing modes, and in the second air guiding configuration, the air guiding member 18 guides the initiated air flow F to (and preferably only to) the second blowing outlet 3 according to the second blowing mode among the blowing modes.

[0042] Therefore, the air guiding member 18 is advantageously designed and configured to define or at least contribute to defining different trajectories of the air flow F inside the hair styling appliance 1, depending on the air guiding configuration in which it is located. When the first and second blowing outlets 2, 3 are carried by the blowing head 10, the air guiding member 18 is preferably arranged inside the blowing head 10, which contributes to a simple and compact design of the blowing head 10. The air guiding member 18 is then advantageously configured to deflect the air flow F leaving the guiding channel 15 arranged in the handle 7 towards one and / or the other of the first and second blowing outlets 2, 3. Even more advantageously, the air guiding member 18 is configured to deflect the air flow F leaving the guiding channel 15 alternately towards one or the other of the first and second blowing outlets 2, 3. Alternatively, the air guiding member 18 may be arranged inside the handle 7, although this is not conducive to the compactness of the latter. Preferably, the air guiding member 18 forms an air guiding duct (or "air deflection duct" or "sleeve") that extends beyond one end of the handle 7, typically beyond the first end 8 of the handle 7. The air guiding member 18 includes at least one air guiding outlet 19 through which, depending on the air guiding configuration in which the air guiding member 18 is located, the air flow F is guided by the air guiding member 18 towards one and / or the other of the first and second blowing outlets 2, 3 (and preferably towards one or the other). Preferably, the air guiding member 18 includes one and only one air guiding outlet 19, so that when the air guiding member 18 is in the first air guiding configuration (in particular Figure 5 , Figure 11 , Figure 13 and Figure 15 ), the air flow F is guided through this air guiding outlet 19 towards the first blowing outlet 2, and when the air guiding member 18 is in the second air guiding configuration (in particular Figure 6 , Figure 12 , Figure 14 and Figure 16) The air flow F is directed through this air guiding outlet 19 to the second blowing outlet 3. This thus simplifies the design of the hair styling appliance 1. 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 shown in the illustrated embodiment, the air guiding member 18 may include an air inlet 20 which is connected to the guiding channel 15 of the handle 7 to collect the air flow F initiated by the blower module 13. Thus, the air guiding member 18 advantageously extends the guiding channel 15 beyond the first end 8 of the handle 7. Advantageously, the air guiding duct formed by the air guiding member 18 includes a hollow tube which is generally cylindrical or preferably frustoconical inside. The hollow tube is open at one of its ends to define the air inlet 20, and the hollow tube preferably has a substantially airtight wall through which the air guiding outlet 19 is formed, such that the air flow F entering through the air inlet 20 exits again through the air guiding outlet 19 along an average outlet direction which is secant to (or at least inclined relative to) the average inlet direction of the air flow F ( Figure 5 and Figure 6 and Figures 11 to 16 ).

[0043] The hair styling appliance 1 further includes a control system to allow the user to alternately select one or the other of the blowing modes, i.e., to control the hair styling appliance 1 to switch from one of the blowing modes to the other, for example from the first blowing mode to the second blowing mode, and conversely from the second blowing mode to the first blowing mode. For this purpose, as shown in the illustrated embodiment, the control system is advantageously connected to the air guiding member 18 to control each switching of the air guiding member 18 from one of the first and second aforementioned air guiding configurations to the other. By acting on the control system, the user can thus alternately select one or the other of the blowing modes of the hair styling appliance 1 from the at least two different blowing modes. The user can thus advantageously select through which of the first and second blowing outlets 2, 3 the air flow F is blown out of the hair styling appliance 1, thereby selecting the operating mode of the hair styling appliance 1. The control system is advantageously separate from the manual control and / or adjustment member 17 for manually controlling and / or adjusting the electrical operation of the hair styling appliance 1 and the cold / hot air switch which the hair styling appliance 1 may include as described above. In particular, it is thus advantageous that the user can select another one of the blowing modes even before starting the blower module 13 of the hair styling appliance 1. For example, as shown in the figure, the control system is advantageously embedded in the blow head 10 and preferably located in the average extension axis B - B' of the blow head 10. Preferably, at least a part of the elements of the control system forms or at least contributes to forming the upper (free) end of the blow head 10. This allows the user to easily and intuitively activate the control system.

[0044] According to the present invention, the hair styling appliance 1 further comprises an indicator system for providing the user with visual information as to which of the blowing modes has been selected by the control system. Here, "visual information" means an indication that can be visually perceived by the user with the naked eye by looking at the hair styling appliance 1 held in one of his / her hands. The indicator system comprises visual selection markings 21, 21', 21" which are alternately (i.e. selectively) visible on the side of that one of the first and second faces 4, 5 which bears the (first or second) blowing outlet 2, 3 corresponding to the (first or second) selected blowing mode. In other words, the visual selection markings 21, 21' are designed and configured to be provided on the side of that one of the first and second faces 4, 5 of the hair styling appliance 1 which bears the selected (first or second) blowing outlet 2, 3 and to be visible from that side, typically when the user's eyes are positioned to face or look at that one of the first and second faces 4, 5 of the hair styling appliance 1 which bears the selected (first or second) blowing outlet 2, 3. Thus, it should be understood that the visual selection markings 21, 21' are only visible on the side of that one of the first and second faces 4, 5 which bears the blowing outlet 2, 3 corresponding to the selected blowing mode.

[0045] Thus, as shown in the figures, in the case where the hair styling appliance 1 only comprises the first and second faces 4, 5 which respectively bear the first and second blowing outlets 2, 3, the visual selection markings 21, 21' are then visible on the following side:

[0046] - when the first blowing mode is selected, on the side of the first face 4 (and not on the side of the second face 5, Figure 3 and Figure 9 the left side) so as to visually inform the user of the fact that the first blowing mode has been selected and thus that the air flow F will be blown out of the hair styling appliance 1 through the first blowing outlet 2,

[0047] - when the second blowing mode is selected, on the side of the second face 5 (and not on the side of the first face 4, Figure 4 and Figure 10 the right side) so as to visually inform the user of the fact that the second blowing mode has been selected and thus that the air flow F will be blown out of the hair styling appliance 1 through the second blowing outlet 3.

[0048] In other words, the visual selection markers 21, 21' are only visible on the side of the face (first face 4 or second face 5) that bears the blowing outlet (first blowing outlet 2 or second blowing outlet 3) preselected by the user with the aid of the control system. This allows the user to very easily and quickly identify which blowing outlet 2, 3 will be used without having to orient the hair styling appliance 1 in a specific manner, and thus which face 4, 5 of the hair styling appliance 1 he must orient towards his hair. Moreover, if the user has any doubts as to which blowing outlet 2, 3 has been selected, he will intuitively tend to look at one or the other of the faces 4, 5 of the hair styling appliance 1, and he will then immediately observe the presence of the visual selection markers 21, 21' on the side of the face (first face 4 or second face 5) through which the work will be done (i.e., the air flow F will be blown out of the hair styling appliance 1).

[0049] More specifically, the visual selection markers 21, 21' are luminous visual selection markers, i.e., the visual selection markers take the form of a specific light (light signal) emitted by an indicator system within the visible field of the human eye, so that when the first blowing mode is selected, on the side of the first face 4 of the hair styling appliance 1, or when the second blowing mode is alternatively selected, on the side of the second face 5 of the hair styling appliance 1, this light is visually perceptible to the user's eyes.

[0050] Therefore, the hair styling appliance 1 according to the invention is particularly practical and intuitive to use, even for users without special professional hair styling skills. Thus, the user can, by means of the control system, freely select one of the various different blowing modes provided by the hair styling appliance 1, and then, by simply taking a look at the hair styling appliance 1, can learn in a particularly simple and practical way which blowing mode has actually been selected among these blowing modes, and through which of the blowing outlets 2, 3 the air flow F will be blown out of the hair styling appliance 1. The implementation of the light-emitting visual selection markers 21, 21', rather than, for example, the implementation of mechanical visual selection markers formed by coloured elements, makes the indicator system more effective in terms of visual perceptibility for the user, whether directly observing or indirectly observing (e.g. through a mirror used during the hair styling operation) the relevant faces 4, 5 of the hair styling appliance 1. In addition, the light-emitting characteristics of the light-emitting visual selection markers 21, 21' allow the user to be informed in a simple and effective way that the hair styling appliance 1 has been powered on and is thus ready to operate. Thus, after selecting one of these blowing modes by acting on the control system (if the desired blowing mode has not yet been selected), the user can very easily ensure that the air flow F will indeed be blown out of the hair styling appliance 1 through those blowing outlets 2, 3 which he / she wants to be directed towards his / her hair in order to benefit from the corresponding blowing mode. The safety of use of the hair styling appliance 1 is also advantageously increased, because, due to the presence of the light-emitting visual selection markers 21, 21' which are directly visible on the faces 4, 5 corresponding to the selected blowing mode, the risk that the user accidentally burns himself / herself by accidentally touching the faces 4, 5 from which the hot air flow F is blown is significantly reduced.

[0051] Preferably, as shown in the illustrated embodiment, the first and second blowing outlets 2, 3 are carried by the blow head 10 of the hair styling appliance 1, and the light-emitting visual selection markers 21, 21' themselves are also carried by the blow head 10. Thus, when the first blowing mode is selected, the light-emitting visual selection markers 21, 21' are arranged on the side of the first face of the blow head 10 of the hair styling appliance 1 which carries the first blowing outlet 2 and are visible from that side. Symmetrically, when the second blowing mode is selected, the light-emitting visual selection markers 21, 21' are arranged on the side of the second face of the blow head 10 of the hair styling appliance 1 which carries the second blowing outlet 3 and are visible from that side. In other words, the blow head 10 thus:

[0052] - includes a first marking area on its first face (the first face 4 of the hair styling appliance 1) where the light-emitting visual selection markers 21, 21' appear when the first blowing mode is selected and the hair styling appliance 1 is powered on, and

[0053] - On its second face (first face 5 of the hair styling appliance 1), it includes a second marking area where the luminous visual selection marks 21, 21' appear when the second blowing mode is selected and the hair styling appliance 1 is powered on.

[0054] This helps to make the hair styling appliance 1 more practical and intuitive to use. In addition, the luminous visual selection marks 21, 21' are arranged at the blow head 10 of the hair styling appliance 1 rather than at the handle 7 of the hair styling appliance 1, which allows ensuring excellent visual accessibility of the luminous visual selection marks 21, 21' without the risk of the visual selection marks being blocked by the hand of the user operating the hair styling appliance 1 (especially the hand of the user holding the handle 7 of the hair styling appliance 1), and allows the user to immediately associate them with the positions of the corresponding blowing outlets 2, 3 when the luminous visual selection marks 21, 21' are visible.

[0055] Preferably, as shown by way of example, the first face 4 of the hair styling appliance 1 has a first longitudinal symmetry plane (or sagittal symmetry plane) S1, and when the first blowing mode is selected, the visual selection marks 21, 21' are advantageously arranged to be aligned (and visible) along the first longitudinal symmetry plane S1. Preferably, as shown by way of example, the second face 5 of the hair styling appliance 1 has a second longitudinal symmetry plane (or sagittal symmetry plane) S2, and when the second blowing mode is selected, the visual selection marks 21, 21' are advantageously arranged to be aligned (and visible) along the second longitudinal symmetry plane S2. These additional technical features can be used independently of each other or preferably in combination, which particularly helps to make the hair styling appliance 1 have particularly intuitive, ergonomic and aesthetic features. Advantageously, as shown, the first and second symmetry planes S1, S2 are orthogonal to the aforementioned plane P1 in which the average extension direction of the hair styling appliance 1 is inscribed. This advantageously contributes to the overall aesthetics of the hair styling appliance and its good balance in the hand.

[0056] In order to further enhance the practical and intuitive features of the hair styling appliance 1, the first and second blowing outlets 2, 3 are preferably arranged on opposite sides of a plane P1 relative to each other, and as described above, the average extension direction of the hair styling appliance 1 (or, where applicable, one of the average extension directions of the hair styling appliance 1) is inscribed in this plane. Thus, the average extension direction advantageously corresponds here to the average extension direction of the part of the hair styling appliance 1 that bears the first and second blowing outlets 2, 3. In the case where the first and second blowing outlets 2, 3 are borne by the blowing head 10 of the hair styling appliance 1, as shown in the illustrated embodiment, the average extension direction of the hair styling appliance 1 preferably corresponds to the average extension axis B - B' of the blowing head 10. Thus, the first and second blowing outlets 2, 3 are then preferably arranged on opposite sides of a plane P1, and the average extension axis B - B' is inscribed in this plane. In this way, when the user views the first blowing outlet 2 and the second blowing outlet 3 separately from the front, the first and second blowing outlets 2, 3 are advantageously not simultaneously visible to the user. By simply rotating the handle 7 of the hair styling appliance 1 by 180° to orient the corresponding one of the first and second blowing outlets 2, 3 towards the hair to be treated, the user can easily alternately use the hair styling appliance 1 according to the first blowing mode or according to the second blowing mode.

[0057] According to a variant (hereinafter referred to as "variant A") implemented in the Figures 1 to 6 illustrated embodiment, the blowing head 10 bears both the first and second blowing outlets 2, 3 and the luminous visual selection marker 21, and the luminous visual selection marker 21 is arranged at a distance from the (first or second) blowing outlet 2, 3 corresponding to the selected blowing mode. In other words, the above-mentioned first and second marking areas are thus arranged respectively on the side of the first face of the blowing head 10 and at a distance from the first blowing outlet 2, and on the side of the second face of the blowing head 10 and at a distance from the second blowing outlet 3.

[0058] For example, the luminous visual selection marker 21 can be arranged at a distance from the corresponding blowing outlet 2, 3, at a distance from the (first or second) blowing outlet 2, 3 corresponding to the selected (first or second) blowing mode, and this distance is between 10 mm and 100 mm, more advantageously between 20 mm and 50 mm. For example, in Figures 1 to 6 the illustrated embodiment, the luminous visual selection marker 21 is, for example, arranged at a distance of approximately 38 mm from the first blowing outlet 2 and at a distance of approximately 43 mm from the second blowing outlet 3. The aforementioned distances advantageously correspond to the shortest distance separating the respective proximal edges of each element from each other.

[0059] According to another variant (hereinafter simply referred to as "variant B"), the blowing head 10 simultaneously bears the first and second blowing outlets 2, 3 and the luminous visual selection marker 21', and the luminous visual selection marker 21' is arranged at the following positions:

[0060] - In Figures 7 to 16 the illustrated embodiment, it is arranged in the (first or second) blowing outlet 2, 3 corresponding to the selected blowing mode, or

[0061] - It is arranged along at least a part of the contour of the (first or second) blowing outlet 2, 3 corresponding to the selected blowing mode.

[0062] In the first case, at least a part of the interiors of the first blowing outlet 2 and the second blowing outlet 3 advantageously respectively define the first marking area and the second marking area. In this way, the luminous visual selection marker 21' is visible through the (first or second) blowing outlet 2, 3 corresponding to the selected blowing mode. In the second case, the first and second marking areas are advantageously arranged along at least a part of the contour of the (first or second) blowing outlet 2, 3 corresponding to the selected blowing mode. Therefore, these first and second marking areas then advantageously are adjacent to the first blowing outlet 2 and the second blowing outlet 3 respectively. For example, the implementation of this "variant B" instead of "variant A" advantageously helps to make the hair styling appliance 1 more practical and intuitive to use, because it allows for easier visual identification of the actually selected blowing outlets 2, 3, that is, the blowing outlets 2, 3 corresponding to the selected blowing mode.

[0063] However, in an alternative variant where the first and second blowing outlets are not (or at least not both simultaneously) borne by the blowing head of the hair styling appliance, it is still possible to arrange the luminous visual selection marker within or along at least a part of the contour of the blowing outlet corresponding to the selected blowing mode.

[0064] When the blowing head 10 simultaneously bears the first and second blowing outlets 2, 3 and the luminous visual selection markers 21, 21', the indicator system can advantageously include:

[0065] - At least first and second light sources 22, 22', 23, 23' (separate light sources) borne by the blowing head 10, such as for example light emitting diodes, and

[0066] - Power supply means for selectively supplying power to the light sources corresponding to the selected blowing mode among the first and second light sources 22, 22', 23, 23', so as to form the luminous visual selection markers 21, 21'.

[0067] The first and second light sources 22, 23 can thus be arranged on the respective sides of the first face 4 of the hair styling appliance 1 (and thus the first face of the blower head 10) and of the second face 5 of the hair styling appliance 1 (and thus the second face of the blower head 10), aligned with or protruding from the outer surface of the blower head 10. Thus, the first and second light sources 22, 23 advantageously directly define the first and second marking regions respectively, which simplifies the design of the indicator system while ensuring excellent visibility of the luminous visual selection markings 21, 21'. For example, as Figure 5 and Figure 6 schematically shown, the first light source 22 can be arranged in the blower head 10, within a first window formed through the housing 6 on the side of the first face of the blower head 10, such that the first light source 22 is positioned aligned with the outer surface of the blower head 10. Conversely, the second light source 23 can be arranged in the blower head 10, within a second window formed through the housing 6 on the side of the second face of the blower head 10, such that the second light source 23 is positioned aligned with the outer surface of the blower head 10.

[0068] Alternatively, the first and second light sources 22', 23' can be arranged in the blower head 10 such that the light emitted by the first and second light sources 22', 23' is visible through the air outlet openings 2, 3 corresponding to the selected blowing mode. In other words, the first light source 22' is thus arranged in the blower head 10 such that when the first light source 22' is powered by the power supply means (first blowing mode), the light emitted by the first light source 22' is visible through the first air outlet opening 2. Correspondingly, the second light source 23' is thus arranged in the blower head 10 such that when the second light source 23' is powered by the power supply means (second blowing mode), the light emitted by the second light source 23' is visible through the second air outlet opening 3. Thus, the first and second air outlet openings 2, 3 advantageously define the first and second marking regions respectively, such that when one of the blowing modes is selected, the luminous visual selection markings 21' are thus advantageously arranged in the air outlet openings 2, 3 corresponding to the selected blowing mode. For example, as Figure 11 and Figure 12 schematically shown, the first light source 22' can be arranged in the blower head 10 and fastened to the internal ducting means 35 (described below) facing the first air outlet opening 2. Conversely, the second light source 23' can be arranged in the blower head 10 and fastened to the internal ducting means 35 facing the second air outlet opening 3.

[0069] Regardless of the arrangement of the first and second light sources 22, 22', 23, 23', the power supply means can advantageously comprise an electrical contactor system 24A, 24B, 25A, 25B, 26A, 26B arranged inside the hair styling appliance 1 to selectively power the first and second light sources 22, 22', 23, 23' according to the first or second configuration in which the air guiding member 18 is located, as Figure 4, Figure 5 and Figure 11 , 12 is schematically shown. Thus, when the first blowing mode is selected and the hair styling appliance 1 is powered on, the power supply device (only) powers the first light sources 22, 22' at the first marking area, thereby forming the luminous visual selection marks 21, 21', which are visible to the user on the side of the first face 4 of the hair styling appliance 1 ( Figure 5 and Figure 11 ). Symmetrically, when the second blowing mode is selected and the hair styling appliance 1 is powered on, the power supply device (only) powers the second light sources 23, 23' at the second marking area, thereby forming the luminous visual selection marks 21, 21', which are visible to the user on the side of the second face 5 of the hair styling appliance 1 ( Figure 6 and Figure 12 ).

[0070] Alternatively, the indicator system may advantageously comprise:

[0071] - at least one light source 27, 27', such as, for example, a light-emitting diode, and

[0072] - an optical guiding device for selectively guiding the light emitted by the light source 27, 27' to the first marking area arranged on the side of the first face 4 of the hair styling appliance 1 or to the second marking area arranged on the side of the second face 5 of the hair styling appliance 1 according to the selected blowing mode. In this way, this (these) light source(s) is / are used both to form the luminous visual selection mark 21' in the first blowing mode and to form the luminous visual selection mark 21' in the second blowing mode, and the optical guiding device ensures the distribution of the emitted light to the first marking area or to the second marking area according to the selected blowing mode.

[0073] In this case, the light sources 27, 27' may be arranged in the blow head 10 or in the handle 7. Preferably, the light source 27, 27' is single, which simplifies the design of the indicator system and reduces the manufacturing cost of the hair styling appliance 1. However, alternatively, multiple light sources may be implemented, for example, to increase the visibility of the luminous visual selection mark 21'.

[0074] Advantageously, the light guide device includes an air guiding member 18. In other words, the air guiding member 18 is advantageously designed and configured to at least partially ensure that the light emitted by the light sources 27, 27' is selectively directed to the first marking area and the second marking area. In this way, this advantageously avoids the need for auxiliary parts to ensure selective light guiding, which particularly helps to simplify the design and make the operation of the hair styling appliance 1 more reliable. To this end, the air guiding member 18 may include, for example, at least one light guiding portion or at least one light reflecting portion.

[0075] In the case where it is desired to implement the above-mentioned variant B, in which the luminous visual selection markers 21' are alternately arranged in the first blowing outlet 2 and the second blowing outlet 3 according to the selected blowing mode, the light sources 27, 27' may advantageously be arranged in the guiding channel 15 described above, and the air guiding member 18 may advantageously have an internal reflection area 28 which is designed and configured to reflect the light emitted by the light sources 27, 27' towards the first blowing outlet 2 when the air guiding member 18 is in the first air guiding configuration and towards the second blowing outlet 3 when the air guiding member 18 is in the second air guiding configuration.

[0076] For example, as Figure 13 and Figure 14 shown in the embodiment shown, the light source 27 may be arranged downstream of the heating element or at the downstream end of the heating element. This allows the visibility of the luminous visual selection markers to be optimized without necessarily having to use a light source 27' with a high light intensity. Alternatively, as Figure 15 and Figure 16 shown in the embodiment shown, the light source 27' may be arranged upstream of the heating element (taking into account the displacement direction of the air flow F), typically between the blower module 13 and the heating element. In this way, placing the light source 27' in the hot air flow F is avoided, which helps to optimize the service life of the light source 27' and / or allows the implementation of a light source 27' that is not intended to operate in a high-temperature environment, and thus has a lower cost.

[0077] For example, the internal reflection area 28 of the air guiding member 18 may be formed by at least a part of the inner surface of the air guiding duct formed by the air guiding member 18 (schematically represented by a grid as in Figures 13 to 16 ), and this part is provided with a light reflecting coating (such as a metallized coating) or has at least one surface state that imparts light reflecting properties to it (such as "mirror polishing").

[0078] Optionally, as previously mentioned, in the case where the hair styling appliance 1 includes a heating element for raising the temperature of the air flow F, the hair styling appliance 1 may advantageously include a control member for controlling the color of the luminous visual selection markers 21, 21' to change the color according to the temperature of the air flow F. This advantageously allows providing auxiliary visual information to the user to inform the user of the temperature of the air flow F blown by the hair styling appliance 1 in a simple, quick, and practical manner. For example, such a control member may include a temperature sensor for measuring the temperature of the air flow F and thus changing the color of the luminous visual selection markers 21, 21'. To obtain such color-changeable luminous visual selection markers 21, 21', for example, the above-mentioned light source(s) may be provided, the voltage of which is controllable to obtain the emission of light of different colors according to the supply voltage of the light source(s). Then, the control member may be designed and configured, for example, to supply power to the light source(s) according to the corresponding supply voltage of the heating element (higher or lower according to the desired temperature of the air flow F).

[0079] Advantageously, the control system for changing the blowing mode of the hair styling appliance 1 includes a movable manual control member, such as a button 29 or a rotary wheel, to allow the user to act on the control system so as to manually select one or another of the blowing modes. "Movable" advantageously means that the manual control member is capable of evolving 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 toggling under the action of a manual mechanical action exerted on it by the user. Preferably, as exemplified in the figure, the manual control member is arranged at the blow head 10, that is, it is carried by (or belongs to) the blow head 10 and not at the handle 7. This allows restricting the risk that the user's hand holding the handle 7 accidentally manipulates the manual control member. More preferably, the manual control member is arranged at a distance from the handle 7 such that the fingers of the user's hand holding the handle 7 cannot reach it. The fingers of the user's hand holding the handle 7 cannot reach the manual control member, but advantageously the fingers of the user's other hand can reach the manual control member. Even more preferably, still as exemplified in the figure, the manual control member is arranged substantially along an axis parallel or coincident with the average extension axis B-B' of the blow head 10, so that the user can reach it from above the blow head 10.

[0080] Advantageously, as shown, the control system of the hair styling appliance 1 is a push - push button 29 type control mechanism (or "push - push motion control mechanism", or "push - push" type button control mechanism) for thus controlling each switching of the hair styling appliance 1 from one blowing mode to another blowing mode. The control system is designed to be actuated by the user, e.g., manually actuated, and thus the control system 20 is designed and configured to convert each push applied by the user (usually by means of the user's finger) on the button 29 of the control system into a switching of the hair styling appliance 1 from one blowing mode to another blowing mode, or at least a switching from one blowing mode towards another blowing mode. The button 29 of the control system then advantageously forms the manual control member as described above. As shown in the illustrated embodiment, the push - push button 29 type control mechanism is thus advantageously connected to the air guiding member 18 to control each switching of the air guiding member 18 from one of the first and second air guiding configurations to the other.

[0081] Thanks to this push - push button 29 type control mechanism, the use of the hair styling appliance 1 is thus particularly simple and intuitive, because the reproduction of the simple pushing action performed by the user on the button 29 of the control mechanism, each time in the same pushing direction, controls each change of the blowing mode of the hair styling appliance 1. Thus, each push applied by the user on the button 29 of the control mechanism controls the cyclic switching of the hair styling appliance 1 from a given initial blowing mode to a subsequent blowing mode, etc., until returning to the said initial blowing mode after the control mechanism has been actuated continuously as many times as there are different blowing modes that the hair styling appliance 1 has. Assuming that the air flow generating member for generating the air flow F of the hair styling appliance 1 is designed to generate the air flow F only according to two different blowing modes, each push applied by the user on the button 29 thus controls an alternating switching from the first operating mode (first blowing mode) of the hair styling appliance 1 to the second operating mode (second blowing mode) of the hair styling appliance 1, then from the first operating mode to the second operating mode, etc.

[0082] Advantageously, the push-button type 29 control mechanism is designed and configured to mechanically control each switching of the hair styling appliance 1 from one blowing mode to another. Thus, the control mechanism is designed and configured to mechanically convert each push exerted by the user (e.g. by means of the user's finger) on the button 29 of the control mechanism into a switching of the hair styling appliance 1 from one blowing mode to another, or at least a switching from one blowing mode to another. Thus, the push-button type 29 control mechanism advantageously has no electrical or electromechanical components, making its design particularly simple, economical and reliable. As shown in the illustrated embodiment, the push-button type 29 control mechanism is thus advantageously mechanically connected to the air guiding member 18 to mechanically convert each movement of the button 29 of the push-button type control mechanism under the action of a push (exerted by the user) on the button 29 into a movement of the air guiding member 18 from one of the first and second air guiding configurations to the other. Thus, advantageously, this is not an electromechanical push-button type control mechanism which would establish an electromechanical connection between the button of the control mechanism and the air guiding member, i.e. it would be designed to convert the mechanical push exerted by the user on the button into an electrical command of an electric actuator which would be connected to the air guiding member 18. The implementation of such a purely mechanical control mechanism advantageously allows the user to change the blowing mode of the hair styling appliance 1 even when the hair styling appliance 1 is not powered (i.e. when the hair styling appliance 1 is switched off or even unplugged). This improves the safety of use of the hair styling appliance 1 since it limits the risk of air being blown directly in a direction not desired by the user, for example towards the face. Nevertheless, the hair styling appliance 1 remains easy to use since the user still retains the possibility of changing the blowing mode of the hair styling appliance 1 while the hair styling appliance 1 is operating. In addition, the implementation of a purely mechanical control system for changing the blowing mode, rather than an electromechanical control system, helps to improve the operating reliability of the hair styling appliance 1 and to reduce its manufacturing and use costs.

[0083] According to a variant (not shown), the button of the push-button type control mechanism is a bistable button. Generally, the control mechanism is then designed and configured such that the button can:

[0084] - evolve from a first stable position (called the release position) to a second unstable position (called the unstable pressing position) under the action of a first push exerted by the user, and

[0085] - then, when the first push exerted by the user stops, automatically return under the action of an elastic return member to a third stable position (called the stable pressing position) located between the first stable position and the second unstable position. The button then remains temporarily locked in said stable pressing position, corresponding to one of the blowing modes of the hair styling appliance 1.

[0086] Conversely, the control mechanism is thus designed and configured such that the button can evolve from a third stable pressed position to a second unstable pressed position under the effect of a second push exerted by the user, the second push following the first push and thus allowing the button to be unlocked, and then, when the second push exerted by the user stops, allowing the button to return to a first stable release position under the effect of the elastic return member. For example, such a bistable push-push button type control mechanism can implement a so-called "heart-shaped" mechanism or kinematics.

[0087] According to a more preferred variant implemented in the illustrated embodiment, the button 29 of the push-push button 29 type control mechanism is a monostable button. Thus, the control mechanism is preferably designed and configured such that the button 29 can:

[0088] - evolve from a first stable position (referred to as the release position, or "non-pressed position", or "rest position") to a second unstable position (referred to as the pressed position) under the effect of a push exerted by the user, and

[0089] - then, when the push exerted by the user stops, automatically return from the pressed position to the release position under the effect of the elastic return member 30.

[0090] It has been found that this "monostable" variant is more advantageous than the above-mentioned "bistable" variant because the button 29 systematically returns to the release position, so that the user can access it equally regardless of the blowing mode selected. In addition, this "monostable" variant is simpler to design and more robust to use.

[0091] Regardless of the "bistable" or "monostable" variant envisaged, the push-push button 29 type control mechanism thus advantageously includes at least one elastic return member 30 for automatically resetting the button 29 from said pressed position to said release position. Preferably, the elastic return member 30 is a spring, in particular a traction, compression or bending spring (leaf spring).

[0092] The button 29 of the push-push button 29 type control mechanism generally has a contact portion 31 or interaction portion for coming into direct contact with the user (e.g., coming into contact with the user's finger) when the user exerts a push on the button 29 to control the change of the blowing mode. Thus, the contact portion 31 defines a part of the outer surface of the button 29 that is oriented towards the outside of the hair care appliance 1, and the user can access and see this part from the outside of the hair care appliance 1. Advantageously, as shown, the contact portion 31 defines the free upper end of the button 29, which is opposite to the lower end of the button 29 that is (permanently) arranged inside the hair care appliance 1.

[0093] As shown in the illustrated embodiment, the control mechanism is thus designed and configured such that when the button 29 is in the released position, the contact portion 31 of the button 29 is preferably (completely) arranged outside the housing 6 of the hair styling appliance 1. Thus, in said released position, and thus without a push applied on the button 29, the button 29 advantageously projects from the outer surface of the hair styling appliance 1, typically from the outer surface of the housing 6 of the hair styling appliance 1. This allows for easy visual and / or tactile identification of the button 29 by the user, contact with said button 29, and manipulation of the button 29. This can also advantageously contribute to limiting the risk of contact between the user and the outer surface of the hair styling appliance 1, which may be hot, and thus limit the risk of burns.

[0094] In any case, the control mechanism is preferably designed and configured such that when the button 29 evolves towards its pressed position under the action of a push applied by the user to switch the hair styling appliance 1 from one of the blowing modes to another, the contact portion 31 of the button 29 is arranged below the outer surface (or at least the outer geometric envelope) of the housing 6 of the hair styling appliance 1 (i.e., such that the button 29 is completely hidden, retracted inside the hair styling appliance 1)( Figures 2 to 4 、 Figures 8 to 10 、 Figure 17 and Figure 18 ). Thus, the risk of inadvertently changing the blowing mode by interaction of the button 29 with the user or environmental elements is advantageously limited.

[0095] As shown in the illustrated embodiment, the contact portion 31 of the button 29 is preferably provided with a recessed area, i.e., an area having a concave surface oriented towards the outside of the hair styling appliance 1. The presence of such a recessed area, preferably located at the center of the contact portion 31, advantageously allows for the placement of the tip of the guiding finger, in particular a part of the finger pad, on the contact portion 31 of the button 29 to help keep the finger so positioned for effectively applying a driving force on the button 29 to control the change of the blowing mode, and this can even be achieved especially in the absence of visual contact with the button 29, and for example when the user is busy observing the appearance of the luminous visual selection markers 21, 21'.

[0096] According to a variant (not shown), the control mechanism can be designed and configured to convert each push applied by the user on the button of the control mechanism into a switch from one blowing mode to another blowing mode of the hair styling appliance 1. In this case, a single push applied by the user on the button of the control mechanism allows switching the hair styling appliance 1 from one blowing mode to another. Once the hair styling appliance 1 has executed this other blowing mode, the user can then stop applying his pushing force on the button. According to another more preferred variant implemented in the illustrated embodiment, the push-button type control mechanism of the push-button 29 is designed and configured to convert each push applied by the user on the button 29 of the control mechanism into a switch, a transition from one blowing mode to another blowing mode of the hair styling appliance 1, and then, when the push applied by the user stops, automatically complete the switching of the hair styling appliance 1 to another blowing mode under the action of the automatic return of the button 29 to the stable release position (non-pressed position). In other words, the change of the blowing mode is then only initiated by the pressure applied by the user on the button 29 and then automatically completed by the control mechanism. This particularly allows the user to change the blowing mode more easily, intuitively, and quickly.

[0097] In particular, depending on the construction and configuration of the air guiding member 18, different kinematics of the air guiding member 18 can be envisaged. However, particularly in order to simplify the design of the hair styling appliance 1 and improve its compactness, the air guiding member 18 is preferably mounted so as to be able to rotate and pivot between at least a first and a second air guiding configuration along the rotation axis D-D', as shown in the illustrated embodiment. A control system, such as the push-button type control mechanism of the push-button 29 described above, then controls the switching of the air guiding member 18 from one of the first and second air guiding configurations to the other by rotating the air guiding member 18 along the rotation axis D-D' by a predetermined rotation angle. Even more preferably, the air guiding member 18 is mounted so as to be able to rotate relative to the handle 7 of the hair styling appliance 1, and the rotation axis D-D' of the air guiding member 18 preferably coincides with or even more preferably is parallel to the longitudinal extension axis A-A' of the handle 7.

[0098] Thus, as shown in the illustrated embodiment, the air guiding member 18 is arranged in the blowing head 10. Advantageously, the air guiding duct formed by the air guiding member 18 may include a generally internally frustoconical hollow tube (as described above), the axis of rotation of which is advantageously formed by the longitudinal extension axis of the air guiding member 18. The longitudinal extension axis of the air guiding member 18 advantageously coincides with the mean extension axis B - B' of the blowing head 10. The respective extension axes of the blowing head 10 and the air guiding member 18 advantageously are collinear with the mean longitudinal extension axis A - A' of the handle 7. The air guiding duct extends through the guiding channel 15 arranged inside the handle 7 by the prolongation of the large base of the generally internally frustoconical hollow tube, and the air inlet 20 of the air guiding duct is arranged at this base. Thus, the effective passage cross-section of the air flow F inside the tube decreases in the direction away from the handle 7 along the longitudinal extension axis of the air guiding member 18.

[0099] As described above, the air guiding member 18 preferably includes a single air guiding outlet 19. The air guiding outlet 19 is formed in the wall of the hollow tube and advantageously extends along the longitudinal extension axis of the air guiding member 18. Thus, the air guiding outlet 19 is formed as a pore extending longitudinally in a direction coplanar with the longitudinal extension axis of the air guiding member 18. Even more advantageously, the air guiding outlet 19 has an outlet cross-section that narrows at the second end towards the side wall of the air guiding member 18. The general internal frustoconical shape of the tube of the air guiding duct advantageously allows the homogenization of the curve of the air flow F circulating inside the tube. The air guiding outlet 19 is advantageously provided with a plurality of air deflectors 32 (rectifier vanes), called "primary deflectors", to rectify the air flow F that leaves through the air guiding outlet 19 from the air inlet 20 of the air guiding member 18 and, depending on the selected blowing mode, optimally direct the air flow F towards the first blowing outlet 2 or the second blowing outlet 3. In turn, in the embodiment shown in the figure, the blowing head 10 advantageously includes a first duct portion 33 and a second duct portion 34, the first duct portion 33 being arranged to ensure the air communication between the air guiding outlet 19 of the air guiding member 18 and the first blowing outlet 2 when the air guiding member 18 is in the first air guiding configuration ( Figure 5 、 Figure 11 、 Figure 13 and Figure 15 ), and the second duct portion 34 being arranged to ensure the air communication between the air guiding outlet 19 of the air guiding member 18 and the second blowing outlet 3 when the air guiding member 18 is in the second air guiding configuration ( Figure 6 、 Figure 12 、 Figure 14 and Figure 16)Ensure the air communication between the air guiding outlet 19 and the second blowing outlet 3. As shown in the figure, the first and second duct portions 33, 34 can advantageously be at least partially defined by an internal duct device 35, which thus constitutes a "two-way" internal duct device (or "two-way distributor"). The internal duct device 35 is advantageously housed inside the blow head 10 and is advantageously fixedly connected to the handle 7 of the hair styling appliance 1. Thus, when the air guiding member 18 is in the first air guiding configuration (in particular Figure 5 , Figure 11 , Figure 13 and Figure 15 ), the air guiding outlet 19 of the air guiding member 18 is in air communication with the first duct portion 33 and thus with the first blowing outlet 2. On the other hand, the tube wall of the air guiding member 18 then closes the second duct portion 34 of the internal duct device 35. Conversely, when the air guiding member 18 is in the second air guiding configuration (in particular Figure 6 , Figure 12 , Figure 14 and Figure 16 ), the air guiding outlet 19 of the air guiding member 18 is in air communication with the second duct portion 34 and thus with the second blowing outlet 3. The tube wall of the air guiding member 18 then closes the first duct portion 33 of the internal duct device 35.

[0100] In terms of optimal rectification and guidance of the air flow F, the blow head 10 can then advantageously include, as shown in the figure:

[0101] - A first output air deflector 36 ("first secondary air deflector") for rectifying the air flow F directed from the air guiding outlet 19 of the air guiding member 18 to the first blowing outlet 2 when the air guiding member 18 is in the first air guiding configuration, and

[0102] - A second output air deflector 37 ("second secondary air deflector") for rectifying the starting air flow F directed from the air guiding outlet 19 of the air guiding member 18 to the second blowing outlet 3 when the air guiding member 18 is in the second air guiding configuration,

[0103] When the air guiding member 18 is in the first air guiding configuration (in particular Figure 5 , Figure 11 , Figure 13 and Figure 15 ), a plurality of said air deflectors 32 at the air guiding outlet 19 of the air guiding member 18 are arranged to be aligned with a plurality of said first output air deflectors 36, and when the air guiding member 18 is in the second air guiding configuration (in particular Figure 6 , Figure 12 ,Figure 14 and Figure 16 ) When, respectively, a plurality of the air deflectors 32 of the air guiding outlet 19 of the air guiding member 18 are arranged to be aligned with a plurality of the second output air deflectors 37.

[0104] Furthermore, it has been found that such alignment of the air deflectors 32 with the first output air deflector 36 / second output air deflector 37 is advantageous in the case of implementing the aforementioned variant B and when the light sources 27, 27' are arranged in the guiding duct 15 of the air flow F, because it allows preventing the light reflected by the internal reflection area 28 of the air guiding member 18 from spreading to the first and second blowing outlets 2, 3. Thus, the visibility of the luminous visual selection marker 21' from the outside of the hair styling appliance 1 to the user is optimized.

[0105] As mentioned above, in order to ensure the mechanical link between the button 29 of the push-push button type control mechanism and the air guide member 18, and therefore to transmit the mechanical push force exerted by the user on the button 29 to the air guide member 18, the control mechanism preferably comprises a rotary coupling part 38 forming a cam and mechanically connected on the one hand to the air guide member 18 and on the other hand preferably to the button 29. Said button 29 is advantageously fixed to at least one pin 39 (or small roller) forming a follower, which cooperates with the cam so that each push exerted on the button 29 drives the rotary coupling part 38 in rotation along the axis of rotation and the air guide member 18 accordingly in rotation along its axis of rotation D-D'. Preferably, as shown in the illustrated embodiment, the button 29 of the push-push button 29 type control mechanism is mounted to perform a linear translation, more preferably a purely linear translation, along the translation direction CC' relative to the rest of the hairdressing appliance 1, in particular to its handle 7, between a non-pressed position (or release position) and a pressed position as described above. In this way, the movement of the button 29 under the action of the push exerted by the user is a pure linear translation movement, i.e., according to the linear sliding connection, with the same average direction as the push exerted by the user. Therefore, the manipulation of the button 29 is particularly easy and intuitive for the user, whatever its position and orientation relative to the user when using the hairdressing appliance 1. Alternatively, although less advantageous in terms of simplicity of design and size, and also less advantageous in terms of ergonomics, the button can be, for example, mounted so as to be rotatable or pivotable or toggled, and constructed and arranged so that the contact portion of the button describes a curved trajectory in the shape of an arc of a circle under the action of the push exerted by the user. Even more preferably, the button 29 is arranged relative to the rotary coupling part 38 so that the linear translation direction CC' of the button 29 coincides with the axis of rotation of the rotary coupling part 38. Thus, each push exerted by the user on the button 29 drives a linear translation displacement of the button 29 and preferably directly drives the rotation of the rotary coupling part 39 along the translation direction CC' of the button 29, which is particularly simple and compact in design, since there are preferably no intermediate parts between the button 29 and the rotary coupling part 38. Alternatively, the linear translation direction CC' of the button can be arranged parallel to and offset relative to the rotation axis of the rotary coupling part 38, or arranged obliquely or orthogonally to the rotation axis of the rotary coupling part 38, which is however disadvantageous for the simplicity and compactness of the design of the control mechanism. Advantageously, the rotary coupling part 38 is fixed in rotation relative to the air guide part 18, the rotation axis of the rotary coupling part 38 coinciding with the corresponding rotation axis D-D' of the air guide part 18. In this way, each movement of the button 29 under the effect of a push exerted by the user drives the rotary coupling part 38 and the air guide part 18 to rotate together along the common rotation axis at said predetermined rotation angle.This contributes to the simplicity and reliability of the design and operation of the hair styling appliance 1. For example, as shown in the figure, the rotary coupling part 38 and the air guiding part 18 can be assembled together in a shape complementary manner and fixed together by a threaded connection or by clamping / snapping or gluing. Alternatively, the rotary coupling part 38 and the air guiding part 18 may be able to form an integral part together.

[0106] Preferably, as shown in the attached embodiment, the rotary coupling part 38 more specifically forms a grooved drum cam. Thus, the rotary coupling part 38 includes at least one rotating cylindrical part provided with a groove 40 forming a cam track, which is defined by two opposite side walls of the groove 40 and is intended to be penetrated by a pin 39 forming a transmission part of the button 29. Thus, the pin 39 is captured inside the groove 40, which helps to ensure a reliable mechanical connection between the button 29 and the rotary coupling part 38. Even more preferably, the groove 40 is an outer peripheral groove that extends around the entire perimeter of the rotating cylindrical part and is self - enclosed. Each time the control of the blowing mode change occurs, the rotation of the rotary coupling part 38 along its axis of rotation can thus occur in the same rotational direction.

[0107] For example, in the embodiment shown in the figures, the button 29 is mounted so as to be able to perform a (pure) rectilinear translation (sliding connection) along its translation direction C-C', which translation direction C-C' coincides with the axis of rotation of the rotary connection part 38. Preferably, the rectilinear translation direction C-C' is parallel or coincides with the mean extension axis B-B' of the blow head 10, which mean extension axis B-B' itself is advantageously parallel or coincides with the axis of rotation D-D' of the air guiding member 18, which axis of rotation D-D' itself is advantageously parallel or coincides with the mean longitudinal extension axis A-A' of the handle 7. Thus, it is advantageous, in particular when the four aforesaid axes and directions A-A', B-B', C-C', D-D' coincide, to obtain a particularly simple construction and a particularly compact hair styling appliance 1. The button 29 advantageously comprises a lateral skirt 41 with a circular cross-section, which rotates along the rectilinear translation direction C-C' and which is arranged parallel to the rotating cylindrical part of the rotary connection part 38 and at least partially covers said cylindrical part. The button 29 is not connected to a single pin 39, but to two pins 39 forming a follower, which two pins 39 are arranged on either side of the rectilinear translation direction C-C' so as to make the mechanical connection between the button 29 and the rotary connection part 38 more reliable. The free end of each pin 39 is received in a recess 40 of the cam groove of the grooved drum formed here by the rotary connection part 38. In order to ensure a stop for the button 29 so that it does not rotate relative to the rest of the hair styling appliance 1, in particular relative to the handle 7 of the hair styling appliance 1, and in order to guide the translational displacement of the button 29 along the rectilinear translation direction C-C', a part of each pin 39 is received inside a respective oblong guiding aperture 42, which guiding aperture 42 is formed in a part which is immovable relative to the handle 7 (such as a part integral with the aforesaid internal piping means 35). In order to facilitate the assembly of the hair styling appliance 1, once the button 29 has been assembled so as to cover the rotating cylindrical part of the rotary connection part 38, each pin 39 can be defined by a cylindrical pin which is press-fitted into an orifice formed through the wall of the lateral skirt 41 of the button 29, so that the part of the pin defining such a pin 39 forming a follower extends radially inside the button 29, while the opposite part of the pin extends radially outside the button 29 and is captured in one of the oblong guiding apertures 42.

[0108] Advantageously, the push - type button 29 - type control mechanism includes an elastic reset member 30, as described above, such as, for example, a compression spring. The elastic reset member 30 is configured and arranged to automatically reset the button 29 to its stable release position (non - pressed position) when the push applied by the user on the button 29 stops. As shown in the figure, the compression spring can be arranged between the inner surface of the button 29 and the surface of the rotary coupling part 38. The cam formed by the rotary coupling part 38 is preferably constructed and configured in a specific way such that the following implementation of the rotation of the air guiding member 18 by the predetermined rotation angle allows the hair styling appliance 1 to switch from one blowing mode to another through the corresponding switching of the air guiding member 18 from one air guiding configuration to another:

[0109] - Only for the first part of the predetermined rotation angle, by the movement of the button 29 under the action of the push applied by the user on the button 29 of the push - type button - type control mechanism,

[0110] - Then, for the remaining part of the predetermined rotation angle, when the push applied by the user stops, under the combined action of the elastic reset member 30 and the cam, by the oppositely - directed movement of the button 29.

[0111] In this way, as mentioned as a preferred variant previously, the change of the blowing mode is only initiated by the push applied by the user on the button 29, and after the user has stopped pushing on the button 29 of the control mechanism, the change of the blowing mode is automatically completed by the control mechanism. Therefore, the user advantageously only needs to provide a part of the force required to rotate the air guiding member 18 by the predetermined rotation angle to switch the air guiding member 18 from one of its air guiding configurations to another. As described above, this particularly allows the user to change the blowing mode more easily, intuitively, and quickly. Even more preferably, the cam is constructed and configured in a specific way such that for 50% or less of the predetermined rotation angle (i.e., at most 50%, for example, only 30%, 40%, or 50%), the rotation of the air guiding member 18 by the predetermined rotation angle is achieved by the movement of the button 29 of the control mechanism under the action of the push applied on the button 29, and then, for the remaining part of the predetermined rotation angle (i.e., 50% or more, for example, 50%, 60%, or 70%), when the applied push stops, the rotation of the air guiding member 18 by the predetermined rotation angle is achieved by the oppositely - directed movement of the button 29 under the combined action of the elastic reset member 30 and the cam.

[0112] For example, this feature can be implemented in the following manner: Adjust the curve of the cam path defined by the groove 40 of the above-mentioned grooved drum cam to define at least two continuous cam path portions forming inclined planes with opposite slopes, wherein the travel of the pin 39 forming the follower drives the air guide member 18 to rotate by a predetermined rotation angle in the following manner. First, when the user applies a push on the button 29 to move it from the release position to the pressed position, the pin 39 travels along the first portion of the cam path and slides against one side wall of the groove 40 forming the first inclined plane, thereby driving the rotary coupling part 38 to rotate by a first rotation angle. Then, when the user stops pushing on the button 29, the elastic return member 30 automatically returns the button 29 to its release position (unpressed position), and then the pin 39 passes through the second portion of the cam path. This time, it slides against the other side wall of the groove 40 forming the second inclined plane (whose slope is opposite to that of the first inclined plane). The pin 39 is pressed against the second inclined plane under the action of the elastic return member 30, thereby forcing the rotary coupling part 38 to rotate by a second rotation angle in the same direction. The slope of the first inclined plane is selected to be equal to or greater and more distinct than the slope of the second inclined plane, such that the first rotation angle is thus smaller than the second rotation angle, and the sum of the first and second rotation angles corresponds to the predetermined rotation angle. In this way, the first rotation angle corresponds to the movement initiated by the user's push, while the second rotation angle corresponds to the above-mentioned automatic complementary movement.

[0113] For example, as shown in the illustrated embodiment, the switching of the air guide member 18 from one of the first and second air guide configurations to the other is achieved by a predetermined rotation angle of rotating the air guide member 18 by 180° about its rotation axis D-D'. Therefore, by rotating 360° about its rotation axis D-D' under the action of two consecutive pushes applied on the button 29, the air guide member 18 can advantageously change the angular configuration twice, alternating between the first and second air guide configurations. Then, the grooved drum cam can be advantageously constructed and configured such that the rotation of the air guide member 18 by the predetermined rotation angle is implemented as follows:

[0114] - Only for 90° (the first rotation angle) (i.e., 50%), under the action of the push applied by the user on the button 29, through the pure linear translational movement of the button 29 from its release (stable) position to its pressed (unstable) position,

[0115] - Then, for the remaining 90°, when the push applied by the user stops, under the combined action of the elastic return member 30 and the grooved drum cam, through the pure linear translational movement of the button 29 in the opposite direction from its pressed (unstable) position to its release (stable) position.
