Definitions
- the present invention relates to a hair dryer allowing adaptation of the air flow by automatically compensating the pressure loss due to a reduction in the outlet section caused by an accessory mounted on the outlet of the hair dryer.
- Hair dryers are often equipped with means of controlling and adjusting parameters of the air blown by the device, such as speed, flow rate or temperature. Air flow and/or temperature are generally selected by the user.
- the document US 5,790,749 discloses a hair dryer comprising a mechanism measuring radiation emitted by the hair.
- This hair dryer also includes a control mechanism that acts jointly on airflow and temperature to regulate the flow of hot air during drying based on measurements of radiation emitted by the hair.
- the document WO 2012/076885 illustrates a hair dryer which includes a fan and regulating means automatically controlling operation of the fan so as to maintain, at least substantially, a constant airflow volume during use.
- the document CN103349418 describes a hair dryer capable of automatically adjusting airflow.
- the hair dryer includes modules for sensing humidity, storing and comparing data, controlling and changing the speed of air flow.
- the document US 2006/0098962 discloses a hair dryer comprising a microprocessor controlled by software to receive a set of information measured by sensors, such as temperature, pressure, motor rotation speed, current consumption by the motor and resistance heating,...
- the microprocessor is programmed to continually check the data, but also to adjust this data in relation to control variables.
- the document DE102007047647 discloses a hair dryer that adapts the fan speed depending on the accessory placed on the air outlet of the housing.
- hair dryer is a consumer product, its price must remain affordable and hair dryers equipped with sensors of all kinds (temperature, pressure, etc.) and complex data management systems do not correspond not meet this criterion and make these hair dryers very expensive.
- hair dryers can be equipped with different accessories, such as nozzles, diffusers, brushes or combs for shaping the hairstyle. These accessories generally obstruct the air outlet and modify the effective section of the hair dryer outlet.
- the present invention offers a simple solution for adapting the air flow depending on the accessory mounted on the device.
- FIG. 2 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.
- 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.
- accessory 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. .
- 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.
- 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.
- the microprocessor adapts the speed, in order to increase the rotation speed of the fan to compensate for the reduction in outgoing air flow.
- 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.
- 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.
- the first step is to measure the current intensity of the motor 7.
- 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.
- the intensity - unlike previously - increases slightly.
- 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.
- the intensity is measured again in order to detect the addition of an accessory.
- the drop in air flow is limited to a maximum of 45%, preferably to 40%, particularly preferably to 35%.
- 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 .
- 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.
- 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.
- 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.
- 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%.
- the hair dryer housing includes a removable silencer.
- the silencer generally includes one or more noise attenuation elements (open cell foam, etc.).
- 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.
- 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.
- 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.
- Indicators for activation/deactivation of the hair dryer, heating elements and ion generator may be provided on the handle of the device.

Un exemple de sèche-cheveux 1 selon l'invention est illustré à la
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
En effet, comme illustré par les graphiques des
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
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
Comme représenté sur l'organigramme de la
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
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
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
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.
