Cet objectif est atteint par un aspirateur comportant un boîtier et un moto-ventilateur destiné à créer une dépression dans un tube d'aspiration dont l'extrémité est équipée d'un suceur, le boîtier comprenant une unité de commande pouvant faire fonctionner le moto-ventilateur selon au moins deux modes, caractérisé en ce que l'aspirateur comprend un moyen de détection de présence du suceur et en ce que l'unité de commande active un premier mode de fonctionnement lorsque le suceur est détecté et un deuxième mode de fonctionnement lorsque le suceur n'est pas détecté.This objective is achieved by a vacuum cleaner comprising a housing and a motor-fan intended to create a vacuum in a suction tube whose end is equipped with a nozzle, the housing comprising a control unit capable of operating the motorcycle. fan according to at least two modes, characterized in that the vacuum cleaner comprises means for detecting the presence of the nozzle and in that the control unit activates a first mode of operation when the nozzle is detected and a second mode of operation when the nozzle is not detected.

Ainsi, grâce au moyen de détection et à l'unité de commande associée, la puissance de l'aspirateur est toujours adaptée en fonction du suceur équipant l'aspirateur.Thus, thanks to the detection means and the associated control unit, the power of the vacuum cleaner is always adapted according to the nozzle fitted to the vacuum cleaner.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, prise à titre d'exemple non limitatif, en référence à la figure unique annexée représentant un aspirateur selon l'invention.Other features and advantages of the invention will emerge from the description which follows, taken by way of non-limiting example, with reference to the single appended figure showing a vacuum cleaner according to the invention.

La présente invention concerne un aspirateur 1 équipé de sa chaîne d'accessoires 2. La chaîne d'accessoires 2 comprend de façon connue en soi un flexible 14 dont une extrémité est connectée à l'aspirateur et l'autre extrémité à une crosse 15 permettant à un utilisateur de manipuler la chaîne d'accessoires 2. La crosse 15 est également connectée à un tube de liaison 12 dont l'extrémité est équipée d'un suceur 10. Selon l'exemple d'illustration de l'invention, tel que le montre la figure 1, le suceur est de forme rectangulaire. Toutefois, la présente invention n'est pas limitée à cette forme rectangulaire, et peut être mise en oeuvre par exemple sur un suceur de forme triangulaire.The present invention relates to a vacuum cleaner 1 equipped with its accessory chain 2. The accessory chain 2 comprises, in a manner known per se, a hose 14, one end of which is connected to the vacuum cleaner and the other end to a butt 15 enabling a user to manipulate the accessory chain 2. The stick 15 is also connected to a connecting tube 12 whose end is equipped with a nozzle 10. According to the illustrative example of the invention, such as shows it figure 1 , the nozzle is rectangular. However, the present invention is not limited to this rectangular shape, and can be implemented for example on a nozzle of triangular shape.

L'aspirateur possède notamment un moto-ventilateur 24 susceptible de créer un flux d'aspiration d'air dans le tube et dans le suceur. L'aspirateur comprend également un dispositif de filtration des déchets (non représenté) permettant de retenir les déchets aspirés dans le boîtier de l'aspirateur 1. Ce dispositif de filtration peut comprendre soit un sac, soit un dispositif de séparation cyclonique à un ou plusieurs étages.The vacuum cleaner has in particular a motor-fan 24 capable of creating a flow of air intake into the tube and into the nozzle. The vacuum cleaner also comprises a waste filtration device (not shown) making it possible to retain the waste sucked into the housing of the vacuum cleaner 1. This filtration device may comprise either a bag or a cyclone separating device with one or more stages.

Le boîtier de l'aspirateur est équipé de roues 21, 23 pour assurer le déplacement de l'aspirateur 1. Le boîtier comprend également une sortie d'air par laquelle l'air préalablement débarrassé des déchets par le dispositif de filtration est évacué.The housing of the vacuum cleaner is equipped with wheels 21, 23 to move the vacuum cleaner 1. The housing also comprises an air outlet through which the air previously disposed of waste by the filtration device is evacuated.

La puissance électrique délivrée au moto-ventilateur est commandée par une unité de commande électronique 25.The electric power delivered to the fan motor is controlled by an electronic control unit 25.

Selon l'invention, l'unité de commande permet d'établir au moins deux modes de fonctionnement du moto-ventilateur. Chaque mode de fonctionnement correspond à une puissance électrique distincte délivrée au moto-ventilateur. L'un des modes de fonctionnement correspond au fonctionnement selon la puissance maximum du moto-ventilateur.According to the invention, the control unit makes it possible to establish at least two modes of operation of the motor-fan. Each mode of operation corresponds to a distinct electric power delivered to the fan motor. One of the operating modes corresponds to the operation according to the maximum power of the fan motor.

L'unité de commande comprend un moyen de détection 26 de la présence du suceur 10 sur la chaîne d'accessoires 2. Selon une première variante, le moyen de détection comprend un dispositif sans fil apte à détecter une balise correspondante sur le suceur. A titre d'exemple, le moyen de détection comprend un lecteur 26 d'étiquette d'identification par radiofréquence. Par ailleurs, le suceur 10 est équipé d'une étiquette 16 d'identification par radiofréquence (RFID Tag). Lorsque le suceur est connecté à la chaîne d'accessoires, le lecteur d'étiquette par radiofréquence fournit un signal correspondant à la présence du suceur 10 à l'unité de commande 25 de l'aspirateur. Sur réception de ce signal, l'unité de commande 25 déclenche le fonctionnement du moto-ventilateur 24 selon un mode particulier.The control unit comprises a detection means 26 for the presence of the nozzle 10 on the accessory chain 2. According to a first variant, the detection means comprises a wireless device capable of detecting a corresponding beacon on the nozzle. By way of example, the detection means comprises a radio frequency identification tag reader 26. Furthermore, the nozzle 10 is equipped with a radio frequency identification tag 16 (RFID Tag). When the nozzle is connected to the accessory chain, the radio frequency tag reader provides a signal corresponding to the presence of the nozzle 10 to the control unit 25 of the vacuum cleaner. Upon receipt of this signal, the control unit 25 triggers the operation of the motor fan 24 according to a particular mode.

Selon l'invention, la puissance délivrée au moto-ventilateur 24 par l'unité de commande 25, lorsque le suceur 10 est détecté, est inférieure à la puissance maximale. Par ailleurs, lorsque le suceur 10 n'est pas détecté par le moyen de détection 26, l'unité de commande délivre la puissance maximale au moto-ventilateur 24.According to the invention, the power delivered to the motor-fan 24 by the control unit 25, when the nozzle 10 is detected, is less than the maximum power. Moreover, when the nozzle 10 is not detected by the detection means 26, the control unit delivers the maximum power to the fan motor 24.

Dans une autre variante non représentée, le moyen de détection comprend un circuit électrique le long de la chaîne d'accessoires 2 connectée à l'unité de commande 25. Le suceur 10 assure la fermeture du circuit électrique lorsqu'il est connecté à la chaîne d'accessoires 2. Ainsi, lorsque le suceur 10 n'est pas présent, la tension du circuit électrique est nulle ce qui constitue pour l'unité de commande 25 le signal d'absence du suceur 10 déclenchant le mode de fonctionnement correspondant. Inversement, lorsque le suceur 10 est présent, la tension du circuit électrique est différente de zéro. L'unité de commande 25 déclenche alors un autre mode de fonctionnement.In another variant not shown, the detection means comprises a electrical circuit along the accessory chain 2 connected to the control unit 25. The nozzle 10 closes the electrical circuit when connected to the accessory chain 2. Thus, when the nozzle 10 does not is not present, the voltage of the electrical circuit is zero which constitutes for the control unit 25 the absence signal of the nozzle 10 triggering the corresponding mode of operation. Conversely, when the nozzle 10 is present, the voltage of the electric circuit is different from zero. The control unit 25 then triggers another mode of operation.

Selon un autre mode de réalisation, l'unité de commande comprend également des moyens d'identification du suceur. L'unité de commande comprend un mode de fonctionnement par type de suceur. Ainsi, l'unité de commande permet non seulement d'ajuster le fonctionnement du moto-ventilateur en fonction de la présence ou non du suceur mais également en fonction de type de suceur. En effet, le fonctionnement optimal d'un suceur adapté pour un sol lisse ne nécessite pas la même puissance d'aspiration qu'un suceur adapté pour la moquette ou qu'une turbo-brosse.According to another embodiment, the control unit also comprises identification means of the nozzle. The control unit comprises a mode of operation by type of nozzle. Thus, the control unit not only makes it possible to adjust the operation of the motor-fan according to the presence or absence of the nozzle, but also according to the type of nozzle. Indeed, the optimal operation of a nozzle suitable for a smooth floor does not require the same suction power as a nozzle suitable for carpet or a turbo brush.

Selon la variante représentée, l'étiquette 16 d'identification par radiofréquence du suceur 10 comprend un identifiant caractéristique du suceur. Le lecteur 26 d'étiquette d'identification par radiofréquence est donc capable de reconnaître le type de suceur en fonction de l'identifiant.According to the variant shown, the radiofrequency identification tag 16 of the nozzle 10 comprises a characteristic identifier of the nozzle. The radio frequency identification tag reader 26 is therefore able to recognize the type of nozzle according to the identifier.

Lorsque la détection de la présence du suceur est réalisée par l'intermédiaire d'un circuit électrique le long de la chaîne d'accessoires, le suceur comprend un composant électronique, telle qu'une résistance, monté en série sur le circuit électrique. La valeur de la résistance est différente d'un type de suceur à l'autre. Lorsqu'un suceur est connecté, la valeur de la tension mesurée par l'unité de commande dans le circuit électrique est alors différente d'un suceur à l'autre.When detection of the presence of the nozzle is performed via an electrical circuit along the accessory chain, the nozzle comprises an electronic component, such as a resistor, mounted in series on the electrical circuit. The value of the resistance is different from one type of nozzle to another. When a nozzle is connected, the value of the voltage measured by the control unit in the electrical circuit is then different from one nozzle to another.

L'aspirateur selon l'invention fonctionne de la façon suivante. Lors de la mise en route de l'aspirateur, le moyen de détection 26 transmet un signal représentatif de la présence ou non du suceur 10 à l'unité de commande 25. La puissance correspondant au signal est délivrée au moto-ventilateur 24. Ainsi, lorsqu'un suceur 10 est détecté, la puissance correspondant au fonctionnement optimal de ce suceur est délivrée au moto-ventilateur 24.The vacuum cleaner according to the invention operates as follows. When the vacuum cleaner is switched on, the detection means 26 transmit a signal representative of the presence or absence of the nozzle 10 to the control unit 25. The power corresponding to the signal is delivered to the fan motor 24. Thus, when a nozzle 10 is detected, the power corresponding to the optimal operation of this nozzle is delivered to the motor-fan 24.

Si aucun suceur 10 n'est détecté, la puissance maximum est délivrée au moto-ventilateur. Ainsi, l'utilisateur peut utiliser la crosse 15 seule pour aspirer des déchets volumineux d'accès difficile.If no nozzle 10 is detected, the maximum power is delivered to the fan motor. Thus, the user can use the butt 15 alone to suck bulky waste of difficult access.

Lorsque l'aspirateur 1 selon l'invention comprend également les moyens d'identification du suceur 10, la puissance délivrée au moto-ventilateur 24 est adaptée au suceur 10 connecté à la chaîne d'accessoires.When the vacuum cleaner 1 according to the invention also comprises the identification means of the nozzle 10, the power delivered to the motor-fan 24 is adapted to the nozzle 10 connected to the accessory chain.

Ainsi, selon l'invention, en ajustant la puissance délivrée au moto-ventilateur dans la zone de fonctionnement optimal du suceur 10, l'énergie électrique consommée par l'aspirateur est donc réduite au juste nécessaire. Toutefois, la puissance maximum du moto-ventilateur reste disponible pour des utilisations très ponctuelles sans le suceur 10.Thus, according to the invention, by adjusting the power delivered to the fan motor in the optimum operating area of the nozzle 10, the electrical energy consumed by the vacuum cleaner is reduced to just what is necessary. However, the maximum power of the motor-fan remains available for very punctual uses without the nozzle 10.
