- the second one-piece part 701 from which the insulating pins 72 originate and the first one-piece part 700 from which the heating pins 70 originate are superimposed, with the second one-piece part 701 forming the insulating pins 72 placed on and against the first one-piece part 700 forming the heating pins 70, the latter protruding through openings 701 A provided through the second one-piece part 701 .
- the hairdressing appliance 1 comprises, in addition to the heating element 4 formed by the heating pins 70, means for emitting steam, and preferably steam, configured to subject to a flow of steam (preferably steam) the hair in contact with the heating element 4.
- the head 3 is advantageously provided with one or more steam ejection orifices 710, belonging to said emission means of steam, to subject the hair engaged by the head 3 to a flow of steam.
- the hairdressing device 1 is, in this preferred embodiment, designed so that hair is simultaneously:
- said substance preferably water in a liquid state in the form of a mist of droplets and/or microdroplets, or - a mixture of said substance (preferably water) in the gaseous state and of said substance (preferably water) in the liquid state in the form of a mist of droplets and/or microdroplets .
- water vapour should not be limited to its strictly scientific definition and here covers water in the gaseous state, the particles of liquid water in suspension in the air, or a mixture of gaseous water and liquid water particles (droplets) suspended in the air.
- the term "water” can mean any liquid containing mainly water (that is to say at least 50% by weight of water, and preferably at least 80% by weight of water, even more preferably at least 95% by weight of water) and capable of being transformed into steam, and thus includes distilled water, running tap water, but also various aqueous solutions containing elements cosmetics, olfactory, etc.
- Said means for emitting steam comprise for example, as illustrated:
- liquid preferably water
- said flow of vapor preferably water vapour
- a supply device 6 for supplying liquid, preferably liquid water, to the vaporization device 5.
- the vaporization device 5 comprises for example a vaporization chamber 50 provided with an inlet 501 for supplying liquid and at least one outlet 502 for steam.
- the vaporization device 5 also comprises a first heating device 51 designed to heat the vaporization chamber 50 and thus transform, within the vaporization chamber 50, the liquid water into water vapour.
- the first heating device 51 is formed for example by resistive elements capable of heating by Joule effect (for example one or more heating elements, or thermistor(s), with a “Positive Temperature Coefficient” (PTC)), said resistive elements being advantageously in contact with said vaporization chamber 50.
- Said vapor outlet 502 is for its part advantageously in fluid communication with the surrounding outside air, preferably permanently, preferably via at least one vapor ejection orifice 710 arranged on the side of the front face 3A, as will be described in more detail below.
- the said vapor ejection orifice(s) 710 is (are) in fluid communication with the interior of the vaporization chamber 50 via a vapor channeling device 52 connected from a side to the outlet 502 and on the other side to said at least one orifice 710 for steam ejection.
- the second heating device 40 of the heating element 4 is separate from said first heating device 51 of the vaporization chamber 50.
- the vaporization chamber 50 is permanently maintained at atmospheric pressure, which avoids having to resort to an outlet valve, due to the absence of a rise in pressure of the vapor. within the chamber 50 and the device 1 .
- the absence of risk of overpressure and therefore the absence of the need to have means to prevent or manage such overpressures
- the temperature of the water vapor flow does not substantially exceed 100°C.
- Said supply device 6 for its part comprises, for example, a reservoir 60 for storing a quantity of liquid (preferably liquid water) and a pump 61 connected to said reservoir 60 and to said vaporization device 5.
- the reservoir 60 is for example removable, that is to say it is detachable from the main body of the device 1, which makes it possible to dispense with an earth connection for the power supply of the device 1 .
- the tank 60 is preferably substantially at atmospheric pressure.
- said pump 61 is a peristaltic pump, which allows very fine control of low flow rates and guarantees relatively constant flow rates.
- the device 1 is therefore designed, in the preferred embodiment illustrated in the figures, to subject the hair engaged by the head 3 to a thermomechanical steam treatment, according to which the hair is simultaneously subjected to:
- a fluidic action which is in this case a steam treatment, consisting in subjecting the hair engaged by the head 3 and in contact with the heating element to steam (preferably steam) 4, advantageously via the orifice(s) 710 for steam ejection/steam pins 71 which will be described below.
- steam preferably steam
- the brushing pins 7 include, in addition to the heating pins 70 and the insulating pins 72, a plurality of steam pins 71 which each incorporate at least one respective one of said orifices 710 for ejecting steam.
- each steam pin 71 incorporates a steam ejection orifice 710, which is advantageously connected to a source of steam, formed for example by the steaming device 5 and the supply device 6 associated described in the foregoing. Said steam pins 71 thus contribute to forming said steam emission means.
- each vapor ejection orifice 710 is advantageously in fluid communication with the interior of the vaporization chamber 50 via the channeling device 52.
- the steam pins 71 thus assume, in more than their mechanical brushing function, a steam sprayer function, that is to say that each steam pin 71, with its steam ejection orifice 710, advantageously forms a steam projection nozzle (of preferably water vapour).
- a steam sprayer function that is to say that each steam pin 71, with its steam ejection orifice 710, advantageously forms a steam projection nozzle (of preferably water vapour).
- the mechanical treatment of the hair under the effect of a resistive force generated by the hair against the steam pins 71 is advantageously combined with a fluidic treatment of the hair (supply of steam via the steam ejection orifice 710 of the steam pins 71).
- the term “combined” is understood here in the sense of simultaneous performance of said mechanical and fluidic treatments on the same zone of hair.
- the steam pins 71 are integral with the heating pins 70, that is to say that in this case the steam pins 71 and the heating pins 70 are advantageously formed by a single piece in one piece.
- the steam pins 71 and heating pins 70 are formed by said first one-piece part 700 (shown in isolation in FIG. 7) mentioned above.
- the steam pins 71 are, like the heating pins 70, anodized, to allow them to retain a smooth surface even when their temperature is high.
- each steam pin 71 is formed by a respective one of said heating pins 70.
- some of the heating pins 70 are provided with an orifice 710 of ejection of steam, in order to form a steam pin 71 .
- the steam pins 71 also play the role of heating pins, in addition to their steam diffusion function, and they too are advantageously heated at least by thermal conduction by means of the second heating device 40 mentioned above. This means that the steam pins 71 contribute, in this preferred embodiment, to forming both the heating element 4 and the means for emitting steam (preferably steam).
- the mechanical treatment of the hair under the effect of a resistive force generated by the hair against the steam pins 71 is, even more advantageously, combined not only with a fluidic treatment of hair (steam supply via the steam ejection orifice 710 of the steam pins 71 contributing to form the steam emission means) as mentioned previously, but also with a heat treatment of the hair (heat supply via the pins steam 71 contributing to form the heating element 4).
- a fluidic treatment of hair steam supply via the steam ejection orifice 710 of the steam pins 71 contributing to form the steam emission means
- a heat treatment of the hair heat supply via the pins steam 71 contributing to form the heating element 4.
- each of said heating pins 70 and/or said steam pins 71 has, in cross-section, a substantially oblong shape, as illustrated in the figures. Thanks to this oblong shape, which gives the pins concerned (heating pins 70 and/or steam pins 71) a substantially flattened shape, in the shape of a paw, the heat exchange with the hair is optimized since the shape of the heating pins 70 provides a maximum exchange surface during the passage of the hair against the pins.
- each steam bar 71 preferably has, as shown in the figures, a substantially flattened shape with two opposite faces, separated by the thickness of the steam bar 71, said steam ejection orifice 710 opening on at least one of said two opposite faces, and preferably on said two faces, in which case the steam is projected on each side of the steam pin 71, which makes it possible to improve the diffusion of the steam within the wicks of hair.
- the steam ejection orifice 710 which opens onto at least one of the faces of the steam pin 71, that is to say substantially perpendicular to the axis of longitudinal extension of the steam pin 71 in question, the steam leaves the steam pin 71 with an incidence which is substantially parallel to the mean plane of the front face 3A, which not only makes it possible to reduce the risk of burns the scalp during use, but also ensures a particularly effective projection of water vapor since it makes it possible to treat the locks of hair on their height.
- each steam ejection orifice 710 is preferably provided over at least half , and preferably over at least two-thirds, of the height of the steam bar 71 which incorporates it.
- each vapor ejection orifice 710 extends longitudinally, in the form of a single opening or of a plurality of stepped openings, over a height advantageously comprised between 3 mm and 15 mm, even more preferably between 7 mm and 10 mm, and for example over a height of approximately 8 mm. Thanks to this technical feature, the entire lock of hair being brushed can be subjected to the flow of steam, which allows effective treatment, particularly in terms of correcting hair surface defects and improving their shine.
- the hairdressing appliance 1 is advantageously designed to be in an operational operating mode EN, that is to say a normal, nominal operating mode, in which the operating parameters of the hairdressing appliance 1, and possibly all the operating parameters of the hairdressing device 1, are, in the absence of positive intervention by the user, substantially constant, or do not vary according to a large amplitude, or even vary automatically according to a predefined and advantageously periodic pattern (sinusoidal or crenellated for example) which can correspond for example to a pulsed vapor flow.
- the operational operating mode EN corresponds to a stationary, cruising regime of the hairdressing device 1 .
- the device 1 Before being in the operational operating mode EN in question, the device 1 is for example designed to be in a transient operating mode ET during which one, or several, or all of the operating parameters of the device hairstyle 1 evolve, preferably continuously and gradually, until they reach, for example, their nominal values corresponding to the aforementioned operational mode of operation EN.
- the device 1 when starting up the device 1, which corresponds for example to a power supply of the latter (preferably controlled by a switch), the device 1 is first of all in the transient operating mode. AND, during which the heating element 4 gradually rises in temperature, as do the dedicated organs of the means emission of water vapor (first heating device 51).
- the transient operating mode ET is then followed by the operational operating mode EN, in which the device 1 remains until it is, for example, switched off (end of electrical power supply) by the user.
- the transition from the transient operating mode ET to the operational operating mode EN is preferably carried out automatically, without positive intervention by the user, who can however be warned of reaching the operational operating mode EN by any suitable signaling means. (light / or sound signal, burst of steam, etc.).
- the device 1 is in the operational mode EN once a predetermined time has elapsed from the start-up (power supply) of the device 1.
- the predetermined time in question which may possibly depend on certain technical characteristics of the device 1 (electrical power for example) is advantageously between 10 s and 60 s, without this range being of course limiting.
- said heating pins 70 when the device 1 is in the operational operating mode EN, said heating pins 70 have a first surface temperature (that is to say a surface temperature), the value of which is for example at at least equal to 110° C., while the flow of steam (preferably steam) emitted by the steam ejection orifices 710 has a mass flow whose value is at least equal to 0.5 g/min (grams per minute), and is preferably at least equal to 0.8 g/min.
- the surface of the heating element 4 formed by the heating pins 70 and possibly the steam pins 71 which are intended to come into contact with the hair during the engagement of the latter by the head 3 has a temperature corresponding to said first surface temperature.
- the value of the mass flow rate of said flow of water vapor emitted by the hairdressing appliance 1, preferably at the level of the head 3, is greater than or equal to 0.5 g/min.
- the insulating pins 72 have a second surface temperature (that is to say a surface temperature) whose value is lower than that of said first surface temperature.
- the value of said second surface temperature in operational operating mode EN is low enough to avoid any risk of burns or discomfort when the insulating spikes 72 come into contact, via their top, with the scalp of the user.
- the aforementioned mass flow rate is advantageously determined by calculating the difference in mass of the tank 60 for a predetermined duration in operational operating mode EN.
- weight and time measurement are advantageously used to determine mass flow.
- the mass and the difference in mass of the reservoir 60 can be determined easily and accurately with common weighing instruments, by carrying out several measurements, the results of which are for example averaged.
- the tank 60 filled with water is weighed.
- the scale is then tared before removing the reservoir 60 from the scale pan.
- the tank 60 - which now contains less water - is weighed again on the already tared scale.
- a measurement of the mass of liquid water moved by a pump in a given time is also equivalent to a measurement of the flow rate (volume per unit time) of the pump.
- the steam flow is pulsed, so that said mass flow varies cyclically, periodically, for example according to a slotted pattern, it will be possible, if necessary, to measure an average value and / or for example exclude from the measurements the periods of time corresponding substantially to an absence of flow.
- the invention has made it possible to demonstrate that the simultaneous supply of heat and steam, in particular with the specific values of temperature and mass flow rate retained and set out in the foregoing, makes it possible to reduce way significant the number of surface defects of the hair, on the scales of the latter.
- the hair because of this reduction in the number of defects, thus presents a smoother surface, which reflects the light in a more homogeneous way, in the manner of a specular reflection, which makes the hair appear shinier, softer and more flexible. Due to this reduction in defects, the hair also has fewer catching points, that is to say they are less likely to cling to each other and are sensorially softer.
- the brushing pins 7, of which the heating pins 70, the insulating pins 72 and preferably the steam pins 71 form part, are organized in at least a plurality of rows, R1, R1', R1", RT", R2, R2', R2", R2'", R3 substantially parallel to the longitudinal direction X-X'.
- Said rows R1, R1, RT, R1", RT", R2, R2', R2", R2'”, R3 advantageously extend in a substantially rectilinear manner, parallel to the longitudinal direction materialized by the central longitudinal axis X- X'.
- said rows comprise at least a first primary row R1 which includes at least a first plurality 70A of said heating pins 70.
- said first primary row R1 comprises only heating pins 70, that is to say that it is formed exclusively by the first plurality 70A of heating pins 70. It is however perfectly possible, without departing from the scope of the invention, that said first row R1 not only includes the first plurality 70A of said heating pins 70, but also other pins, for example one or more insulating pins 72 and/or one or more steam pins 71, without departing from the scope of the invention.
- the first primary row R1 extends longitudinally along a first axis X1 -XT parallel to the longitudinal direction X-X'.
- said plurality of rows also comprises a first secondary row R2 which in this case extends along a second longitudinal axis X2-X2' parallel to the longitudinal direction materialized by the central longitudinal axis X-X'.
- Said first secondary row R2 includes at least a first plurality 72A of said insulating pins 72.
- the first secondary row R2 is formed only of insulating pins 72, in which case it only includes said first plurality 72A of insulating pins 72. It is however quite possible, without departing from the scope of the invention, that said first secondary row R2 includes, in addition to said first plurality 72A of insulating pins 72, one or several heating pins 70 and/or one or more steam pins 71.
- the first primary R1 and secondary R2 rows are substantially adjacent, i.e. no other row of said plurality of rows is interposed between them.
- said first primary R1 and secondary R2 rows are also offset longitudinally so that heating pins 70 of said first primary row R1 are not aligned with insulating pins 72 of said first secondary row R2 according to a transverse direction YY' substantially perpendicular to said longitudinal direction X-X'.
- Said transverse direction YY' advantageously corresponds, and as illustrated in the figures, to the width of the head 3.
- the front face 3A of the head 3 thus extends along a mean plane which is advantageously parallel to a plane passing through the axis central longitudinal XX' materializing the longitudinal direction, and by the transverse axis YY' materializing said transverse direction.
- the aforementioned longitudinal shift implies that there are, in the first primary row R1, heating pins 70 which are not located to the right, in a transverse direction parallel to the transverse axis Y-Y', of an insulating pin 72 of the first secondary row R2. In other words, at least some of the heating pins 70 of the first primary row R1 do not form with insulating pins 72 of the first secondary row R2 respective transverse rows parallel to the transverse direction Y-Y'.
- the orthogonal projection on a projection plane which passes through the central longitudinal axis XX' and is perpendicular to the 'transversal axis Y-Y', of one or more of the insulating pins 72 of the first secondary row R2, occupies at least part of the free space located between the orthogonal projections of two adjacent heating pins 70 of the first primary row R1 on this same projection plane.
- Such a longitudinal offset of the first primary row R1 and first secondary row R2 makes it possible to promote the mechanical tensioning of the hair so as to effectively press the hair on and against the heating pins 70.
- the hair is stretched by alternating insulating pins 72 and heating pins 70, which allows the hair to be pressed against the heating pins 70, thus increasing the heat exchange surface.
- the first primary R1 and secondary R2 rows are offset longitudinally so that at least some of the pins 70, 72 of said first primary R1 and secondary R2 rows are staggered, i.e. to say that the orthogonal projection of at least some of the insulating pins 72 on the aforementioned projection plane is located substantially equidistant from the respective orthogonal projections of two adjacent heating pins 70 of the first primary row R1 on this same projection plane.
- the insulating spikes 72 advantageously play the role of tensioning spikes, since they preferably contribute, in addition to their thermal insulation function, to imparting a mechanical tension to the hair engaged by the head 3, which makes it possible to flatten them effectively on and against the heating pins 70.
- the insulating pins 72 thus make it possible, in cooperation with the other brushing pins 7 (including the heating pins 70 and the steam pins 71), to stretch the hair engaged by the head 3 in order to press them laterally on and against the heating pins 70 and/or the steam pins 71, thus allowing a better heat exchange as well as a better supply of steam to the locks of hair concerned.
- none of the heating pins 70 of said first primary row R1 is aligned with any one of the insulating pins 72 of said first secondary row R2 in the transverse direction Y-Y'.
- the quotient Q1 of the number N1 of pins of the first primary row R1 which are not aligned in the transverse direction YY' with pins of the first secondary row R2, by the total number N1 T of pins of said first primary row R1 is equal to 100%.
- the quotient Q1 in question may well be less than 100% without departing from the scope of the invention.
- the technical effect of tensioning and improvement of the heat exchange surface is significantly perceptible when said quotient Q1 is at least equal to 50% (that is to say that at least the half of the heating pins 70 of the first primary row R1 are not aligned with insulating pins 72 of said first secondary row R2 in a direction parallel to the transverse axis Y-Y'), and preferably is at least equal to 70 %, and even more preferably is at least equal to 80%.
- the pins 7 of said rows of said plurality of rows R1, R1', R1", R1'", R2, R2', R2", R2'", R3 are regularly spaced from each other in the longitudinal direction XX' within the same row of said plurality of rows.
- the longitudinal distance separating two adjacent pins 7, corresponding to the pitch of the row concerned is substantially constant.
- the longitudinal offset of the first primary R1 and secondary R2 rows can be obtained for example by positioning an end pin of said first primary row R1 (c i.e. a pin corresponding to one of the ends of said first primary row R1) and an end pin of said first secondary row R2 (i.e. a pin corresponding to one of the ends of said first secondary row R2) offset in the transverse direction Y-Y'.
- said end pins of the first primary row R1 and secondary R2 may be aligned in the transverse direction Y-Y', but for the pitch of the first primary row R1 to be different from the pitch of the first secondary row R2, and/or that at least one of said pitches is variable, to generate a transverse misalignment of at least some of the pins of said first primary R1 and secondary R2 rows. It is also possible to randomly space the pins within each of said first primary row R1 and first secondary row R2 to obtain the required transverse misalignment.
- this longitudinal offset is implemented for all the rows of said plurality of rows R1, RT, R1", RT", R2, R2', R2", R2'", R3, so that each row of said plurality of rows R1, RT, R1", RT", R2, R2', R2", R2'", R3 is offset longitudinally (in the sense explained above) with respect to each other row of said plurality of rows adjacent to it, so that pins belonging to adjacent rows of said plurality of rows R1, RT, R1", RT", R2, R2', R2", R2'", R3 are not aligned in said direction transverse YY' (in the sense detailed above in relation to the first primary R1 and secondary R2 rows).
- each of the pins of each of said rows R1, RT, R1", RT", R2, R2', R2", R2'", R3 is offset transversely with the pins of the adjacent rows.
- R2", R2'", R3 is arranged so that:
- Ni designates the number of pins of said row Ri which are not aligned in the transverse direction Y-Y' with pins of another adjacent row of said plurality of rows R1, R1', R1", R1'” , R2, R2', R2", R2'", R3, while Nh designates the total number of pins of said row Ri.
- the QRI quotient referred to above it is perfectly possible for the QRI quotient referred to above to be, for each of said rows or for some of them, less than 100%, without departing from the scope of the invention.
- quite significant effects in terms of improving heat transfer in particular are obtained when, for each row Ri of said plurality of rows R1, R1', R1", R1'", R2, R2', R2′′, R2′′′, R3, ⁇ Ri > 50%, preferentially when QRI > 70%, and even more preferentially when QRI > 80%.
- the pins 7 are spaced apart according to said longitudinal direction XX' by a longitudinal spacing DL comprised between 1.5 mm and 5 mm, preferably between 2 mm and 4 mm.
- a longitudinal spacing DL comprised between 1.5 mm and 5 mm, preferably between 2 mm and 4 mm.
- the aforementioned values advantageously correspond to the maximum longitudinal spacing between two adjacent pins 7 within the same row.
- said longitudinal spacing DL can vary over the height of the spikes 7, depending on the profile of the latter, which can for example be thinner from the bottom upwards in the longitudinal direction X-X'.
- the implementation of a longitudinal gauge DL included in the aforementioned ranges represents an optimal compromise for:
- the aforementioned longitudinal distance DL also makes it possible, when the pins concerned are insulating pins 72, to obtain a good compromise between the desired mechanical tension effect and the fluid passage of the hair between the pins.
- each row of said plurality of rows R1, R1', R1", R1'", R2, R2', R2", R2'", R3 delimits with another row of said plurality of rows which is adjacent, an inter-row space whose width DT in the transverse direction YY' is between 1 mm and 8 mm, preferably between 1 mm and 5 mm.
- the aforementioned values advantageously correspond to the maximum width of the inter-row space, insofar as said width may vary over the height of the spikes 7, depending on the profile of the latter, which may for example go thinner from bottom to top in the transverse direction.
- the use of an inter-row space whose width DT, measured in the transverse direction Y-Y', is included in the aforementioned preferential ranges allows an excellent compromise between comfort of use and efficiency in terms of detangling and heat transfer.
- the brush pins 7 are distributed over the front face 3A according to a distribution pattern which has a plane P of central symmetry.
- Such a symmetrical arrangement facilitates the use of the device 1, the latter thus forming an advantageously ambidextrous device 1, usable both by a user of the right hand or the left hand, but also on the left side or on the left side. right of the user's head while advantageously maintaining an identical relative movement/treatment gesture: typically from the root to the tip of the hair.
- Such a symmetrical arrangement also contributes to simplifying the industrial manufacture of the hairdressing device 1 .
- said heating pins 70 are arranged in a plurality of primary rows R1, R1', R1", R1'" including said first primary row R1, while said insulating pins 72 are arranged in a plurality of secondary rows R2 , R2', R2", R2'" including said first secondary row R2, said primary rows R1, R1', R1", R1'" and secondary rows R2, R2', R2", R2'” being arranged alternately and forming part of said aforementioned plurality of rows.
- said plurality of rows is thus formed by alternating primary rows formed exclusively of heating pins 70 and secondary rows formed exclusively of insulating pins 72.
- two rows primary heating pins 70 are advantageously separated by a secondary row of insulating pins 72
- reciprocally two secondary rows of insulating pins 72 are advantageously separated by a primary row of heating pins 70.
- This alternating arrangement of the heating pins 70 and insulating pins 72 preferably with a longitudinal offset between all the adjacent rows as mentioned previously, makes it possible to optimally flatten the hair engaged by the head 3 on the heating pins 70, thus improving the heat transfer within the hair, which contributes to a embellishment effect, while allowing them to be detangled effectively.
- said plurality of rows comprises a mixed row R3 including at least on the one hand a second plurality 72B of said insulating pins 72 and on the other hand said plurality of steam pins 71, said insulating pins 72 and steam pins 71 being arranged alternately within said mixed row R3. That means that in the longitudinal direction materialized by the central axis X-X', each insulating pin 72 of the mixed row R3 is adjacent to at least one steam pin 71 of the mixed row R3, while reciprocally each steam pin 71 of the mixed row R3 is adjacent to at least one insulating pin 72 of the mixed row R3.
- This configuration makes it possible to confine the jets of steam coming from each steam spike 71, on each side of the latter, and thus to promote optimum diffusion of the steam through the strands of hair engaged by the head 3.
- the alternation, within the mixed row R3, of steam pins 71 and insulating pins 72 allows an excellent compromise between the efficiency and the size of the vaporization chamber 50.
- the use of an alternating pattern makes it possible to implements a limited number of steam pins 71 (number on which the size of the vaporization chamber 50 depends) while maintaining an appropriate pitch between the adjacent pins of the mixed row R3, guaranteeing the efficiency of the transfer of steam and heat .
- the mixed row R3 is centered on the head 3.
- This characteristic that the steam pins 71 are arranged substantially in the center of the front face 3A has various advantages.
- a first advantage lies in the safety of use: an emission of steam located in the center of the front face 3A in fact makes it possible to limit the risk of burns.
- Another advantage lies in the fact that the water vapor can act more effectively on the hair because it can escape less easily than if it were emitted from the periphery of the head 3.
- said plurality of secondary rows R2, R2', R2", R2'" includes, in addition to said first secondary row R2 which extends longitudinally along the second axis X2-X2' , a second secondary row R2', which extends for example along a third axis X3-X3', and which is formed by a third plurality 72C of said insulating pins 72.
- Said first and second secondary rows R2, R2' are arranged either side of said mixed row R3, preferably adjacent to the latter.
- said mixed rows R3, first secondary row R2 and second secondary row R2' are offset longitudinally so that the pins of said mixed rows R3, first secondary row R2 and second secondary row R2' are not aligned in the transverse direction Y-Y ', and be by example arranged in staggered rows as shown, in order to press the hair against the steam pins 71 and thus optimize the transfer of heat and steam.
- the quotient Q3 of the number N3 of pins of the mixed row R3 which are not aligned in the transverse direction Y-Y' with pins of the first secondary row R2 or of the second secondary row R2', by the number total N3T of pins of said mixed row R3 is at least equal to 50%, and preferably is at least equal to 70%, and even more preferably is at least equal to 80%.
- said quotient Q3 is equal to 100%.
- the implementation of the mixed row R3 is moreover preferentially independent of the other technical characteristics exposed here, and in particular of the implementation or not of a longitudinal offset of the rows of heating pins and insulating pins.

- Said fourth primary row R1 '” is arranged symmetrically to said third primary row R1 ” with respect to said plane P of central symmetry, and extends longitudinally along a sixth axis X6-X6'.
- said plurality of secondary rows also comprises a third secondary row R2" formed by a fourth plurality 72D of said insulating pins 72, and which extends for example along a seventh axis X7-X7' advantageously interposed between said first axis X1 -X1' and fifth axis X5-X5'.
