Description

DISPOSITIF DE COMMANDE DE LA PUISSANCE DE CHAUFFAGE DEVICE FOR CONTROLLING THE HEATING POWER
D'UNE RESISTANCE ELECTRIQUEOF AN ELECTRIC RESISTANCE
L'invention se rapporte à un dispositif de commande de la puissance de chauffage d'une résistance électrique divisée en plusieurs parties équipant un sèche-cheveux et montée dans un circuit électrique d'alimentation compre¬ nant, un groupe moto-ventilateur destiné à créer un cou¬ rant d'air ainsi que des moyens de commutation suscepti- blés de brancher ladite résistance sous plusieurs modes de puissance.The invention relates to a device for controlling the heating power of an electrical resistance divided into several parts fitted to a hair dryer and mounted in an electrical supply circuit comprising a motor-fan group intended to create an air stream as well as switching means capable of connecting said resistor in several power modes.
Dans les dispositifs connus, l'utilisateur choisit, grâce aux moyens de commutation, le mode de séchage sou- haité qui peut être, par exemple, très chaud, moyen ou froid.In the known devices, the user chooses, by means of the switching means, the desired drying mode which can be, for example, very hot, medium or cold.
Dans bien des circonstances, notamment lors du sé¬ chage des cheveux d'un enfant, le mode choisit se révèle rapidement ou trop chaud ou trop froid et l'ajustement par l'utilisateur devient pratiquement impossible rendant inconfortable cette opération de séchage.In many circumstances, especially when drying a child's hair, the mode chosen is quickly or too hot or too cold and the adjustment by the user becomes practically impossible making this drying operation uncomfortable.
En outre, ces différences brutales de températures s'avèrent néfastes pour la chevelure qui se fixe en un certain état et contrarie par la suite son peignage.In addition, these abrupt differences in temperature prove to be harmful for the hair which fixes itself in a certain state and thwarts its combing thereafter.
Selon l'invention, l'un au moins desdits modes dit "confort" correspond à une puissance et à un débit d'air telles que la température du courant d'air au niveau de la chevelure soit portée dans la plage de 35 à 40°C.According to the invention, at least one of said “comfort” modes corresponds to a power and an air flow such that the temperature of the air stream at the level of the hair is brought in the range from 35 to 40 ° C.
Grâce à ce mode "confort", l'utilisateur peut cor¬ riger instantanément la température de l'air soufflé pour la faire passer soit de l'un des modes chaud ou froid à une température agréable pour le corps humain lui procu- rant une impression de bien être, et qui de plus est bé¬ néfique pour la chevelure.Thanks to this "comfort" mode, the user can instantly correct the temperature of the blown air to change it from one of the hot or cold modes to a temperature that is pleasant for the human body. rant an impression of well-being, and which is also beneficial for the hair.
Les caractéristiques et avantages de 1•invention ressortiront d'ailleurs de la description qui va suivre, prise à titre d'exemple non limitatif, en référence au dessin dans lequel on a représenté en figure unique un schéma électrique du circuit d'alimentation de la résis¬ tance d'un sèche-cheveux selon l'invention.The characteristics and advantages of the invention will become apparent from the description which follows, taken by way of nonlimiting example, with reference to the drawing in which there is shown in a single figure an electrical diagram of the supply circuit of the resistance of a hair dryer according to the invention.
Le dispositif de commande de la puissance de chauf¬ fage d'une résistance électrique 10 auquel se rapporte la présente invention est adapté à équiper un sèche-cheveux du type à main comportant, dans un boîtier (non repré- sente) , un groupe moto-ventilateur 11 destiné à créer un courant d'air et branché dans un circuit électrique d'alimentation de la résistance chauffante 10 dans lequel sont connectés des moyens de commutation 12 susceptibles de brancher ladite résistance sous plusieurs modes de puissance. Comme il est connu en soi, la résistance chauffante 10 est du type résistance en fil bobiné autour d'un support isolant et comportant plusieurs prises re¬ liées aux moyens de commutation 12 de manière, à diviser la résistance en plusieurs parties, par exemple, en trois parties de valeurs différentes 10a, 10b et 10c pour obte¬ nir au moins trois différents modes de puissance fonction du choix des moyens de commutation 12.The device for controlling the heating power of an electrical resistance 10 to which the present invention relates is suitable for equipping a hand-type hair dryer comprising, in a housing (not shown), a motorcycle group. fan 11 intended to create a current of air and connected in an electrical circuit for supplying the heating resistor 10 in which are connected switching means 12 capable of connecting said resistor in several power modes. As is known per se, the heating resistance 10 is of the resistance type of wire wound around an insulating support and comprising several sockets re¬ linked to the switching means 12 so as to divide the resistance into several parts, for example, in three parts of different values 10a, 10b and 10c to obtain at least three different power modes depending on the choice of switching means 12.
Selon l'invention, l'un au moins des dits modes dit "confort" correspond à une puissance et à un débit d'air tels que la température du courant d'air au niveau de la chevelure soit portée dans la plage de 35°C à 40°c. De préférence cette température est choisie entre 37°C et 38°C. Ainsi, grâce à ce dispositif, l'utilisateur peut passer, par exemple, d'un mode très chaud nécessaire à une mise en plis, au mode "confort" procurant immédiate¬ ment au cuir chevelu un abaissement de la température et donc une impression de bien être, ou bien d'un mode froid pour le soin des cheveux très fins au mode "confort" éle¬ vant la température de façon raisonnable sans risque pour le cheveu.According to the invention, at least one of the so-called "comfort" modes corresponds to a power and an air flow such that the temperature of the air stream at the level of the hair is brought within the range of 35 °. C at 40 ° c. Preferably this temperature is chosen between 37 ° C and 38 ° C. Thus, thanks to this device, the user can switch, for example, from a very hot mode necessary for styling, to "comfort" mode immediately providing the scalp with a lowering of the temperature and therefore an impression well-being, or a cold mode for the care of very fine hair in "comfort" mode elevating the temperature in a reasonable manner without risk for the hair.
Ce dispositif est d'autant plus appréciable et sé¬ curisant lorsque l'utilisateur procède au séchage de la chevelure d'un bébé.This device is all the more appreciable and securing when the user dries a baby's hair.
Comme on le voit sur l'exemple de réalisation il- lustré, le circuit électrique d'alimentation est branché aux bornes A et B d'un réseau alternatif de tension 230V et comprend en série un pont d'alimentation 13 du groupe motoventilateur 11 et la partie 10a de la résistance chauffante, et en parallèle à la partie 10a, les parties 10b et 10c reliées respectivement aux moyens de commuta¬ tion 12. Dans cette exemple de réalisation, la partie 10a de la résistance est de l'ordre de 280 watts, tandis que les parties 10b et 10c de cette résistance sont respecti¬ vement de l'ordre de 750 W et 500 W.As can be seen in the illustrated exemplary embodiment, the electrical supply circuit is connected to the terminals A and B of a 230V AC network and comprises in series a supply bridge 13 of the fan unit 11 and the part 10a of the heating resistor, and in parallel to the part 10a, the parts 10b and 10c connected respectively to the switching means 12. In this exemplary embodiment, the part 10a of the resistance is of the order of 280 watts, while the parts 10b and 10c of this resistor are respectively around 750 W and 500 W.
Ces moyens de commutation 12 comportent un premier commutateur 12a destiné à brancher le groupe moto-venti¬ lateur 11 et les différentes parties 10a, 10b et 10c de la résistance 10 pour obtenir différents modes de puis- sance autres que le mode "confort", et un second commuta¬ teur 12b adapté à court-circuiter le premier commutateur 12a et à brancher uniquement la partie 10a de ladite ré¬ sistance avec ledit groupe moto-ventilateur 11 pour ob¬ tenir le mode "confort". Le premier commutateur 12a présente une première double série de plots 14 à 18 et 20 à 24 et une seconde double série de plots 25 à 27 et 28 à 31, susceptibles d'être commutés en ligne par un curseur mobile 32 qui relie les plots de chaque série deux à deux selon un or¬ dre croissant (ou décroissant) par exemple liaison de 15- 16 et 21-22, et simultanément 25-26 et 28-29, tandis que le second commutateur 12b, monté en série entre les pre¬ mière et seconde double séries de plots comporte égale- ment une double série de plots 34,35,36 et 37,38,39 - les plots 35 et 37 étant reliés respectivement aux plots 22 et 24 de la première double série et au plot 27,29,31 de la seconde série et les plots 35 et 38 étant reliés en¬ semble par un conducteur - ainsi qu'un contact mobile 40 susceptible d'occuper au moins deux positions, soit une position normale N pour laquelle il assure la liaison électrique entre les plots 22 et 24 et le plot 27 pour permettre le branchement des parties 10a,10b,10c sous plusieurs modes de puissance fonction du premier commuta- teur 12a, soit une seconde position correspondant au mode dit "confort" référencé par la lettre Ç pour laquelle il assure la liaison des plots 22 et 24 avec les plots 35 et 36 ; le plot 36 étant lui-même relié à une branche élec¬ trique 41 reliée à l'entrée du pont d'alimentation 13 du groupe moto-ventilateur 11.These switching means 12 comprise a first switch 12a intended to connect the motor-driven fan unit 11 and the different parts 10a, 10b and 10c of the resistor 10 in order to obtain different power modes other than the "comfort" mode, and a second switch 12b adapted to short-circuit the first switch 12a and to connect only the part 10a of said resistor with said motor-fan unit 11 to obtain the "comfort" mode. The first switch 12a has a first double series of pads 14 to 18 and 20 to 24 and a second double series of pads 25 to 27 and 28 to 31, capable of being switched online by a movable cursor 32 which connects the pads each series two by two in an increasing (or decreasing) order, for example a link from 15-16 and 21-22, and simultaneously 25-26 and 28-29, while the second switch 12b, mounted in series between the pre ¬ first and second double series of studs also includes a double series of studs 34,35,36 and 37,38,39 - the studs 35 and 37 being connected respectively to the studs 22 and 24 of the first double series and to the stud 27,29,31 of the second series and the pads 35 and 38 being connected together by a conductor - as well as a movable contact 40 capable of occupying at least two positions, ie a normal position N for which it ensures the electrical connection between pads 22 and 24 and pad 27 to allow connection ent parts 10a, 10b, 10c in several power modes depending on the first switch 12a, a second position corresponding to the so-called "comfort" mode referenced by the letter Ç for which it ensures the connection of the pads 22 and 24 with the pads 35 and 36; the pad 36 being itself connected to an electric branch 41 connected to the input of the supply bridge 13 of the motor-fan unit 11.
De plus, les plots 14 à 16 sont susceptibles d'être branchés, par le curseur 32 du premier commutateur, en série avec une diode 42 montée elle-même en série dans le circuit électrique d'alimentation du pont 13 et de la partie 10a de la résistance chauffante.In addition, the pads 14 to 16 are capable of being connected, by the cursor 32 of the first switch, in series with a diode 42 itself mounted in series in the electrical supply circuit of the bridge 13 and of the part 10a. of the heating resistance.
Ainsi, le fonctionnement du sèche-cheveux est le suivant. Supposons que le curseur 32 du premier commuta- teur 12a soit branché sur les plots 15-16;21-22 et 25-Thus, the operation of the hair dryer is as follows. Suppose that the cursor 32 of the first switch 12a is connected to the pads 15-16; 21-22 and 25-
26;28-29, et que le second commutateur 12b soit en posi- tion normale N, alors on obtient, d'une part, la mise en série de la diode 42, le pont d'alimentation 13 et la partie 10a de la résistance, et d'autre part, la mise en parallèle de la partie 10c de la résistance avec l'ensem- ble pont 13 et partie 10a de manière à faire fonctionner le sèche-cheveux en mode chaud sous 640 Watts avec un dé¬ bit voisin de 15 litres par seconde. Dès lors que l'uti¬ lisateur fait passer le second commutateur 12b en sa po¬ sition "confort" C (représentée en traits interrompus) , on modifie immédiatement le branchement du circuit élec¬ trique de manière à alimenter par la liaison des plots 35-36 directement et uniquement le pont 13 et la partie de résistance 10a aux bornes A-B du réseau quelle que soit la position du curseur 32.26; 28-29, and that the second switch 12b is in the posi- normal tion N, then we obtain, on the one hand, the placing in series of the diode 42, the supply bridge 13 and the part 10a of the resistor, and on the other hand, the placing in parallel of the part 10c resistance with the bridge assembly 13 and part 10a so as to operate the hair dryer in hot mode at 640 Watts with a flow rate close to 15 liters per second. As soon as the user switches the second switch 12b to its "comfort" position C (shown in dashed lines), the connection of the electrical circuit is immediately modified so as to supply power via the connection of the pads 35 -36 directly and only the bridge 13 and the resistance part 10a at the terminals AB of the network whatever the position of the cursor 32.
Ainsi, on obtient, d'une part, l'alimentation de la partie 10a résistance de l'ordre de 280 Watts, et d'autre part, un débit de courant d'air du groupe moto-ventila¬ teur 11 choisi dans une plage de 20 à 25 litres d'air par seconde et de préférence de l'ordre de 22,5 litres par seconde.Thus, one obtains, on the one hand, the supply of the part 10a resistance of the order of 280 Watts, and on the other hand, a flow of air current from the motor-fan group 11 chosen in a range of 20 to 25 liters of air per second and preferably of the order of 22.5 liters per second.
Grâce à l'appport du chauffage de la résistance 10a, ce mode "confort" se traduit donc, dans un air ara- biant de 20 à 22°C, par une augmentation de la température de cet air ambiant et donc par une température comprise entre 37°C et 38βC au niveau de la chevelure. Thanks to the heating element 10a heating, this "comfort" mode therefore results, in ambient air from 20 to 22 ° C, by an increase in the temperature of this ambient air and therefore by a temperature comprised between 37 ° C and 38 β C at the level of the hair.
