Description détaillée de l'inventionDetailed description of the invention

Un exemple de sèche-cheveux 1 selon l'invention est illustré à la Figure 2. Celui-ci comprend un boitier 2 muni d'une poignée 3. Comme tous les sèche-cheveux, il peut être muni d'un accessoire de coiffure, monté sur la bouche de sortie d'air 5.An example of a hair dryer 1 according to the invention is illustrated in Figure 2 . This includes a housing 2 fitted with a handle 3. Like all hair dryers, it can be fitted with a hairdressing accessory, mounted on the air outlet 5.

Par « accessoire », on entend un élément fixé de manière amovible sur la sortie d'air du sèche-cheveux, permettant de mettre en forme la coiffure, tel que des buses, des diffuseurs, des brosses ou des peignes. Ces accessoires modifient la section efficace de la bouche de sortie, ce qui augmente la résistance à l'écoulement de l'air et donc modifie également le débit d'air du sèche-cheveux. Dans la présente invention, nous avons choisi d'illustrer le sèche-cheveux selon l'invention muni d'une buse, il est bien entendu que l'homme du métier est capable de remplacer cette buse par tout autre type d'accessoire de coiffure.By “accessory” we mean an element removably attached to the air outlet of the hair dryer, allowing the hairstyle to be shaped, such as nozzles, diffusers, brushes or combs. These accessories change the effective section of the outlet mouth, which increases the resistance to air flow and therefore also changes the air flow of the hair dryer. In the present invention, we have chosen to illustrate the hair dryer according to the invention provided with a nozzle, it is of course understood that those skilled in the art are capable of replacing this nozzle with any other type of hairdressing accessory. .

Tel qu'illustré à la Figure 2, le boitier du sèche-cheveux renferme un ventilateur 6 prévu pour aspirer l'air à l'intérieur du boitier et le faire circuler entre la bouche d'entrée d'air 4 et la bouche de sortie d'air 5. Avant sa sortie, l'air aspiré est chauffé par des éléments chauffants 9, tels qu'une résistance chauffante, grâce à son passage à travers ceux-ci. Le ventilateur 6 est actionné par un moteur 7. Le moteur 7 est un moteur de type sans balai, géré par un microprocesseur 8 permettant d'adapter la vitesse du ventilateur 6 lorsque la consommation de courant du moteur 7 est modifiée.As illustrated in Figure 2 , the hair dryer housing contains a fan 6 designed to suck air inside the housing and circulate it between the air inlet mouth 4 and the air outlet mouth 5. Before its exit , the sucked air is heated by heating elements 9, such as a heating resistance, thanks to its passage through them. The fan 6 is actuated by a motor 7. The motor 7 is a brushless type motor, managed by a microprocessor 8 making it possible to adapt the speed of the fan 6 when the current consumption of the motor 7 is modified.

En effet, comme illustré par les graphiques des Figures 6 et 7, lorsqu'un accessoire est placé sur la bouche de sortie d'air, la consommation en courant du moteur sans balai 7 diminue instantanément, ce qui influence immédiatement le débit d'air. Cela est dû à la modification de la section efficace de la sortie d'air en fonction de l'accessoire utilisé sur le sèche-cheveux. Les valeurs reprises sur ces Figure 6 et 7 sont données à titre d'illustration.Indeed, as illustrated by the graphs of Figures 6 And 7 , when an accessory is placed on the air outlet mouth, the current consumption of the brushless motor 7 instantly decreases, which immediately influences the air flow. This is due to the modification of the effective section of the air outlet depending on the accessory used on the hair dryer. The values shown on these Figure 6 And 7 are given for illustration purposes.

Afin de pallier cette diminution de flux d'air, le sèche-cheveux de l'invention comprend un microprocesseur 8 contrôlant le moteur sans balai 7 permettant d'adapter la vitesse du ventilateur 6 lorsque la consommation (l'intensité) de courant du moteur 7 est modifiée. Le microprocesseur permet donc une adaptation du flux d'air en fonction de l'accessoire monté sur la bouche de sortie d'air. Lorsque la consommation de courant du moteur descend en dessous d'un certain seuil, le microprocesseur adapte la vitesse, afin d'augmenter la vitesse de rotation du ventilateur pour compenser la diminution du flux d'air sortant.In order to compensate for this reduction in air flow, the hair dryer of the invention comprises a microprocessor 8 controlling the brushless motor 7 making it possible to adapt the speed of the fan 6 when the current consumption (intensity) of the motor 7 is modified. The microprocessor therefore allows adaptation of the air flow depending on the accessory mounted on the air outlet. When the motor current consumption drops below a certain threshold, the microprocessor adapts the speed, in order to increase the rotation speed of the fan to compensate for the reduction in outgoing air flow.

L'augmentation de la vitesse du ventilateur est bien entendue adaptée entre certaines limites, et en particulier entre une limite haute et une limite basse, de préférence sur une plage allant de 2000 à 6000 tours par minute, de manière particulièrement préférée sur une plage allant de 3000 à 5000 tours par minute. Sur l'exemple illustré à la Figure 7, la vitesse du moteur est de 21 000 tours par minute lorsqu'aucun accessoire n'est prévu, et est augmentée pour atteindre 24 000 tours par minute lorsque l'accessoire est monté sur le sèche-cheveux.The increase in fan speed is of course adapted between certain limits, and in particular between a high limit and a low limit, preferably over a range going from 2000 to 6000 revolutions per minute, particularly preferably over a range going from 3000 to 5000 revolutions per minute. On the example illustrated in Figure 7 , the motor speed is 21,000 revolutions per minute when no accessory is provided, and is increased to reach 24,000 revolutions per minute when the accessory is mounted on the hair dryer.

Comme représenté sur l'organigramme de la Figure 5, la première étape est de mesurer l'intensité de courant du moteur 7.Dès que la vitesse du moteur est stabilisée, l'intensité de courant est mesurée en permanence par le microprocesseur afin de détecter une chute ou une augmentation de cette intensité. A partir du moment où un accessoire est ajouté sur le sèche-cheveux, l'intensité de courant consommée par le moteur diminue. Lorsque cette intensité chute en dessous d'un certain seuil critique (appelé « Seuil bas »- Figure 8), le microprocesseur détecte qu'un accessoire est placé sur le sèche-cheveux. Le moteur réagit donc en conséquence et augmente sa vitesse afin de compenser la perte de débit due à l'utilisation de l'accessoire et donc à la réduction de section efficace de la bouche de sortie d'air 5. Une fois la vitesse haute atteinte, l'intensité de courant est de nouveau mesurée en permanence. Lorsque l'accessoire est retiré du sèche-cheveux, l'intensité - à l'inverse de précédemment - augmente légèrement. Dès que le courant dépasse un certain seuil (appelé « Seuil haut »- Figure 8), le microprocesseur considère que l'accessoire est retiré du sèche-cheveux. Le moteur réagit donc en conséquence et ralentit afin de revenir à sa vitesse initiale sans accessoire. Dès stabilisation de la vitesse du moteur, l'intensité est à nouveau mesurée afin de détecter l'ajout d'un accessoire.As shown on the organization chart of the Figure 5 , the first step is to measure the current intensity of the motor 7. As soon as the motor speed is stabilized, the current intensity is measured continuously by the microprocessor in order to detect a drop or increase in this intensity. From the moment an accessory is added to the hair dryer, the current consumed by the motor decreases. When this intensity drops below a certain critical threshold (called “Low threshold” - Figure 8 ), the microprocessor detects that an accessory is placed on the hair dryer. The motor therefore reacts accordingly and increases its speed in order to compensate for the loss of flow due to the use of the accessory and therefore to the reduction in effective section of the air outlet 5. Once the high speed is reached , the current intensity is measured again continuously. When the accessory is removed from the hair dryer, the intensity - unlike previously - increases slightly. As soon as the current exceeds a certain threshold (called “High threshold” - Figure 8 ), the microprocessor considers that the accessory is removed from the hair dryer. The motor therefore reacts accordingly and slows down to return to its initial speed without accessories. As soon as the motor speed stabilizes, the intensity is measured again in order to detect the addition of an accessory.

Grâce au mécanisme d'adaptation de l'invention, la chute de débit d'air est limitée au maximum à 45%, de préférence à 40%, de manière particulièrement préférée à 35%. Par exemple, le sèche-cheveux illustré à la Figure 3 est muni d'une buse 11 ayant une section minimale de sortie d'air de 290mm2, alors que le même sèche-cheveux, sans accessoire, a une bouche de sortie d'air de section de 1000mm2. Par « section minimale » de sortie d'air, on entend la section calculée au niveau du passage le plus étroit de la buse, cette section étant une section parallèle à la bouche de sortie 5 du ventilateur. Dans ce cas, cela signifie que la section de la sortie d'air est réduite de 71% lorsque l'accessoire est monté sur l'appareil. Dès lors, un sèche-cheveux de l'art antérieur, qui ne comporte pas d'asservissement du débit d'air à la section de la bouche de sortie, aura au minimum une réduction de débit d'environ 71%, sans tenir compte de la diminution supplémentaire due à la perte de charge. Pour l'accessoire illustré à la Figure 4, la section minimale de sortie d'air de la buse 11 est de 558 mm2, ce qui signifie que la réduction de section est de 44%. Un sèche-cheveux de l'art antérieur aura au minimum une réduction de débit d'environ 44%, sans tenir compte de la diminution supplémentaire due à la perte de charge.Thanks to the adaptation mechanism of the invention, the drop in air flow is limited to a maximum of 45%, preferably to 40%, particularly preferably to 35%. For example, the hair dryer shown in Figure 3 is provided with a nozzle 11 having a minimum air outlet section of 290mm 2 , while the same hair dryer, without accessories, has an air outlet with a section of 1000mm 2 . By “minimum section” of air outlet, we mean the section calculated at the level of the narrowest passage of the nozzle, this section being a section parallel to the outlet mouth 5 of the fan. In this case, this means that the air outlet section is reduced by 71% when the accessory is mounted on the device. Therefore, a hair dryer of the prior art, which does not include control of the air flow at the outlet mouth section, will have at least a reduction in flow of approximately 71%, without taking into account of the additional reduction due to the loss of load. For the accessory illustrated in Figure 4 , the minimum air outlet section of the nozzle 11 is 558 mm 2 , which means that the reduction in section is 44%. A hair dryer of the prior art will have at least a reduction in flow rate of approximately 44%, without taking into account the additional reduction due to pressure loss.

La chute de débit d'air d'un sèche-cheveux selon l'invention est compensée au moins à hauteur de 20 %, de préférence 30%, de manière particulièrement préférée à 50 %. Dans l'exemple illustré par le graphique de la Figure 7, la chute de débit d'air est compensée à 31 %.The drop in air flow of a hair dryer according to the invention is compensated at least by 20%, preferably 30%, particularly preferably 50%. In the example illustrated by the graph in Figure 7 , the drop in air flow is compensated to 31%.

Selon l'invention, le ventilateur 6 comporte une configuration hybride, avec à la fois une composante radiale et une composante axiale (ventilateur de type « mixed flow »).According to the invention, the fan 6 comprises a hybrid configuration, with both a radial component and an axial component (“mixed flow” type fan).

D'autre part, le boitier du sèche-cheveux comprend un silencieux amovible. Le silencieux comporte généralement un ou plusieurs éléments d'atténuation du bruit (mousse à cellules ouvertes, ...).On the other hand, the hair dryer housing includes a removable silencer. The silencer generally includes one or more noise attenuation elements (open cell foam, etc.).

Le sèche-cheveux selon l'invention comprend aussi un générateur d'ions, permettant de générer un flux d'ions à la sortie d'air du sèche-cheveux. L'utilisateur peut choisir d'activer ou non ce générateur d'ion grâce à un bouton de commande situé sur la poignée de l'appareil.The hair dryer according to the invention also comprises an ion generator, making it possible to generate a flow of ions at the air outlet of the hair dryer. The user can choose whether or not to activate this ion generator using a control button located on the handle of the device.

La poignée peut comprendre plusieurs interrupteurs d'activation. Le premier interrupteur actionne le moteur du sèche-cheveux tandis que le second actionne le générateur d'ions. Un interrupteur peut aussi être prévu pour l'élément chauffant, ce qui permet l'utilisation du sèche-cheveux sans chaleur, en mode « froid ». D'autre part, le sèche-cheveux n'a pas besoin de sélecteur de température, étant donné que la température du flux sortant est substantiellement constante, lorsque les éléments chauffants 9 sont activés. Par substantiellement, on entend que la température ne varie pas plus que de plus ou moins 10°C, de préférence 5°C. En effet, étant donné que le flux d'air est adapté grâce au microprocesseur, les éléments chauffants n'ont pas besoin d'avoir différentes puissances de chauffe. Une seule puissance de chauffe est suffisante pour assurer une température substantiellement constante, et le sèche-cheveux est dès lors dépourvu de régulation manuelle de température.The handle may include multiple activation switches. The first switch operates the hair dryer motor while the second switches the ion generator. A switch can also be provided for the heating element, which allows the use of the hair dryer without heat, in “cold” mode. On the other hand, the hair dryer does not need a temperature selector, given that the temperature of the outgoing flow is substantially constant when the heating elements 9 are activated. By substantially, we mean that the temperature does not vary more than plus or minus 10°C, preferably 5°C. Indeed, since the air flow is adapted thanks to the microprocessor, the heating elements do not need to have different heating powers. A single heating power is sufficient to ensure a substantially constant temperature, and the hair dryer therefore does not have manual temperature regulation.

Des témoins d'activation/désactivation du sèche-cheveux, des éléments chauffants et du générateur d'ions peuvent être prévus sur la poignée de l'appareil.Indicators for activation/deactivation of the hair dryer, heating elements and ion generator may be provided on the handle of the device.
