Description
La présente invention concerne le domaine des appareils de nettoyage et, plus particulièrement, un aspirateur à main sans sac, autrement appelé aspirateur à main cyclonique.The present invention relates to the field of cleaning devices and, more particularly, to a bagless hand-held vacuum cleaner, otherwise known as a cyclonic hand-held vacuum cleaner.
Un tel aspirateur a pour vocation d'être compact et porté avec une main pour aspirer des surfaces basses, par exemple un plan de travail ou des marches d'escalier, ou des surfaces rehaussées, par exemple un plafond ou un mur voire un mobilier disposé en hauteur.Such a vacuum cleaner is intended to be compact and carried with one hand to vacuum low surfaces, for example a worktop or staircase steps, or raised surfaces, for example a ceiling or a wall or even furniture arranged in height.
Les aspirateurs à main sans sac sont connus de l'homme du métier. Un tel aspirateur comprend un corps qui est muni à l'arrière d'une poignée de préhension et qui intègre des moyens d'aspiration. L'aspirateur comprend également un tube d'aspiration par l'extrémité avant duquel sont aspirées les impuretés et une chambre de filtration agencée entre le tube d'aspiration et les moyens d'aspiration sur le corps pour recevoir et stocker provisoirement les impuretés aspirées. La chambre de filtration comprend un bol qui communique avec le tube d'aspiration et un élément filtrant qui est logé dans le bol et qui communique avec les moyens d'aspiration.Bagless hand-held vacuum cleaners are known to those skilled in the art. Such a vacuum cleaner comprises a body which is provided at the rear with a gripping handle and which incorporates suction means. The vacuum cleaner also comprises a suction tube through the front end of which the impurities are sucked and a filtration chamber arranged between the suction tube and the suction means on the body to receive and temporarily store the sucked impurities. The filtration chamber comprises a bowl which communicates with the suction tube and a filter element which is housed in the bowl and which communicates with the suction means.
Lors de l'activation des moyens d'aspiration, le flux d'air génère une dépression permettant d'aspirer les impuretés par l'extrémité avant du tube d'aspiration ; le flux d'air chargé d'impuretés circule dans ledit tube puis pénètre dans le bol où les impuretés restent emprisonnées en grande partie grâce à une force centrifuge générée dans ce bol, tandis que l'élément filtrant disposé en aval (en tenant compte du sens de circulation du flux d'air) permet de retenir les fines particules d'impuretés, le flux d'air filtré poursuivant ensuite son circuit dans le corps sous l'action desdits moyens d'aspiration, pour être finalement rejeté dudit corps, par exemple à l'arrière de celui-ci.When the suction means are activated, the air flow generates a vacuum making it possible to suck up the impurities through the front end of the suction tube; the flow of air laden with impurities circulates in said tube then enters the bowl where the impurities remain trapped largely thanks to a centrifugal force generated in this bowl, while the filter element arranged downstream (taking into account the direction of circulation of the air flow) makes it possible to retain the fine particles of impurities, the filtered air flow then continuing its circuit in the body under the action of said suction means, to be finally rejected from said body, by example on the back of it.

A cet effet, l'invention concerne un appareil de nettoyage de type aspirateur à main, nommé « aspirateur » dans la suite de la description.To this end, the invention relates to a cleaning device of the hand-held vacuum cleaner type, called “vacuum cleaner” in the remainder of the description.
Selon l'invention, l'aspirateur comprend un corps muni d'une poignée de préhension agencée à l'arrière de l'aspirateur et de moyens d'aspiration, un tube d'aspiration agencé à l'avant de l'aspirateur et une chambre d'aspiration munie d'un bol communiquant avec le tube d'aspiration, et d'un élément filtrant inséré dans le bol et qui communique avec les moyens d'aspiration. Un tel aspirateur à main ne comporte pas de sac, le bol servant directement au stockage des impuretés aspirées. Un tel aspirateur est fréquemment appelé aspirateur à main cyclonique et permet de générer une force centrifuge dans le bol durant l'aspiration, laquelle assure la dépose d'une grande partie des impuretés dans le fond du bol ; le principe de fonctionnement lors de l'activation des moyens d'aspiration est décrit précédemment et s'applique au cas présent de l'invention.According to the invention, the vacuum cleaner comprises a body provided with a gripping handle arranged at the rear of the vacuum cleaner and suction means, a suction tube arranged at the front of the vacuum cleaner and a suction chamber provided with a bowl communicating with the suction tube, and a filter element inserted into the bowl and which communicates with the suction means. Such a hand-held vacuum cleaner does not include a bag, the bowl serving directly for the storage of the impurities sucked up. Such a vacuum cleaner is frequently called a cyclonic hand vacuum cleaner and makes it possible to generate a centrifugal force in the bowl during the suction, which ensures the deposit of a large part of the impurities in the bottom of the bowl; the principle of operation during the activation of the suction means is described above and applies to the present case of the invention.
De manière remarquable, selon l'invention, l'aspirateur comprend un système de guidage et de maintien agencé entre une face arrière du bol et une face avant du corps pour engager le bol sur le corps jusqu'à atteindre une position de formation de la chambre d'aspiration ou, inversement, pour dégager le bol du corps jusqu'à atteindre une position de séparation. Ce système de guidage et de maintien est configuré pour accompagner le mouvement du bol sur le corps durant son engagement ou son dégagement. On comprend que les termes « arrière » et « avant » sont appréciés en regard de la position de la poignée de préhension, disposée à l'arrière de l'aspirateur, et du tube d'aspiration, disposé à l'avant de l'aspirateur.Remarkably, according to the invention, the vacuum cleaner comprises a guiding and holding system arranged between a rear face of the bowl and a front face of the body to engage the bowl on the body until it reaches a position for forming the bowl. suction chamber or, conversely, to release the bowl from the body until a separation position is reached. This guidance and support system is configured to accompany the movement of the bowl on the body during its engagement or release. It will be understood that the terms “rear” and “front” are appreciated with regard to the position of the gripping handle, arranged at the rear of the vacuum cleaner, and of the suction tube, arranged at the front of the vacuum cleaner. vacuum.
En outre, selon l'invention, l'aspirateur comprend un système de verrouillage agencé entre une partie supérieure avant du bol et une partie avant du corps pour verrouiller le bol sur le corps en position de formation de la chambre d'aspiration ou pour déverrouiller le bol du corps de sorte à le dégager.In addition, according to the invention, the vacuum cleaner comprises a locking system arranged between an upper front part of the bowl and a front part of the body to lock the bowl on the body in the position of forming the suction chamber or to unlock. the bowl of the body so as to release it.
Ainsi, la conception de l'aspirateur selon l'invention permet un positionnement convenable et précis, de manière intuitive, du bol sur le corps pour la formation de la chambre d'aspiration. L'utilisateur positionne la partie du système de guidage et de maintien sur le bol en correspondance avec celle sur le corps, puis engage le bol sur le corps en poussant dessus, ce qui le déplace naturellement ou intuitivement grâce au système de guidage et de maintien jusqu'à atteindre la position de formation de la chambre d'aspiration où le système de verrouillage est enclenché pour maintenir ladite position, le bol étant précisément positionné sur le corps. La position du système de guidage et de maintien, à l'arrière du bol, et celle du système de verrouillage, à l'avant du bol, assurent une répartition convenable des efforts entre le bol et le corps, ce qui réduit les risques de désassemblage du bol en cas de choc de l'aspirateur sur des obstacles durant le nettoyage. Lorsqu'il convient de vider le bol, l'utilisateur déverrouille le bol du corps puis dégage intuitivement le bol du corps en tirant dessus jusqu'à son extraction complète, le mouvement du bol vis-à-vis du corps étant imposé par le système de guidage et de maintien.Thus, the design of the vacuum cleaner according to the invention allows a suitable and precise positioning, intuitively, of the bowl on the body for the formation of the suction chamber. The user positions the part of the guide and support system on the bowl in correspondence with that on the body, then engages the bowl on the body by pushing on it, which moves it naturally or intuitively thanks to the guide and support system until reaching the position of formation of the suction chamber where the locking system is engaged to maintain said position, the bowl being precisely positioned on the body. The position of the guiding and holding system, at the back of the bowl, and that of the locking system, at the front of the bowl, ensure a suitable distribution of forces between the bowl and the body, which reduces the risk of disassembly of the bowl in case of impact of the vacuum cleaner on obstacles during cleaning. When it is appropriate to empty the bowl, the user unlocks the bowl from the body then intuitively releases the bowl from the body by pulling on it until it is completely removed, the movement of the bowl vis-à-vis the body being imposed by the system guiding and holding.
Selon l'invention, le système de guidage et de maintien est configuré pour engager le bol sur le corps en le poussant vers l'arrière sur le corps ou, inversement, lors de son dégagement du corps en le tirant vers l'avant sur le corps. On comprend qu'une multitude de trajectoires du bol sur le corps est possible lors de son engagement et lors de son dégagement, chacune de ces trajectoires nécessitant de pousser vers l'arrière ou de tirer vers l'avant le bol sur le corps pour que le mouvement puisse s'opérer.According to the invention, the guiding and holding system is configured to engage the bowl on the body by pushing it backwards on the body or, conversely, when it is released from the body by pulling it forward on the body. body.

Preferably, the locking system comprises a return element making it possible to return the at least one bolt to the engaged position in the at least one keeper, each bolt comprising an inclined face configured to retract said bolt in contact with the keeper at the end. of movement when engaging the bowl on the body. This allows to lock automatically the bowl on the body once the bowl is in place. Preferably, the locking system comprises two bolts engaging respectively in two keeps, the bolts being positioned in opposition and moving laterally, each on one side of the vacuum cleaner.
Selon une autre réalisation du système de verrouillage, celui-ci comprend un crochet configuré pour se loger sur un bord du corps et assurer le verrouillage du bol en position sur le corps. De préférence, le système de verrouillage comprend un organe de commande agencé sur le bol et un élément de transmission agencé entre l'organe de commande et le crochet pour dégager ledit crochet du bord du corps. La présence de l'organe de commande sur le bol permet avantageusement d'avoir directement en main le bol lors de son déverrouillage, tandis que le corps est maintenu par sa poignée de préhension avec l'autre main. De préférence, le système de verrouillage comprend un élément de rappel permettant de ramener le crochet en position engagée dans le bord du corps, le crochet comprenant une partie recourbée munie d'un pan incliné configuré pour escamoter ledit crochet au contact dudit bord en fin de mouvement lors de l'engagement du bol sur le corps. Cela permet de verrouiller automatiquement le bol sur le corps une fois le bol mis en place.According to another embodiment of the locking system, the latter comprises a hook configured to be housed on an edge of the body and ensure the locking of the bowl in position on the body. Preferably, the locking system comprises a control member arranged on the bowl and a transmission element arranged between the control member and the hook to release said hook from the edge of the body.

This will automatically lock the bowl onto the body once the bowl is in place.
Selon une réalisation de l'invention, le tube est intégré au corps, à l'avant de celui-ci. Cela permet de disposer d'un bol complètement indépendant du tube et du reste de l'aspirateur, ce qui facilite sa manipulation et son nettoyage. On pourrait toutefois envisager une variante où le tube serait intégré au bol, sans sortir du cadre de l'invention. De préférence, selon cette réalisation, le bol comprend une ouverture principale par laquelle est inséré l'élément filtrant et une ouverture secondaire qui communique avec le tube. De préférence, selon cette réalisation, le système de verrouillage est agencé au niveau d'une zone de jonction entre le corps et le tube. On comprend en effet que, du fait que le tube est intégré au corps et forme un ensemble monobloc, la partie avant du corps se confond avec la partie arrière du tube. De préférence, selon cette réalisation, des moyens d'étanchéité sont mis en œuvre entre une extrémité arrière du tube et une partie supérieure avant du bol et entre le corps et une partie supérieure arrière du bol, l'étanchéité étant mise en place lors de la formation de la chambre d'aspiration. Grâce au système de guidage et de maintien et au système de verrouillage qui assurent un positionnement précis du bol sur le corps lors de la formation de la chambre d'aspiration, on garantit à chaque fois la mise en place convenable de l'étanchéité entre le bol et le corps et entre le bol et le tube. Cela permet d'optimiser l'étanchéité et la dépression générée en sortie du tube lors de la circulation du flux d'air.According to one embodiment of the invention, the tube is integrated into the body, at the front of the latter. This makes it possible to have a bowl completely independent of the tube and the rest of the vacuum cleaner, which facilitates its handling and cleaning. One could however envisage a variant where the tube would be integrated into the bowl, without departing from the scope of the invention. Preferably, according to this embodiment, the bowl comprises a main opening through which the filter element is inserted and a secondary opening which communicates with the tube. Preferably, according to this embodiment, the locking system is arranged at a junction zone between the body and the tube. It is in fact understood that, due to the fact that the tube is integrated into the body and forms a one-piece assembly, the front part of the body merges with the rear part of the tube. Preferably, according to this embodiment, sealing means are implemented between a rear end of the tube and a front upper part of the bowl and between the body and a rear upper part of the bowl, the seal being put in place during chamber formation suction. Thanks to the guiding and holding system and to the locking system which ensure precise positioning of the bowl on the body during the formation of the suction chamber, each time we guarantee the proper installation of the seal between the bowl and body and between bowl and tube. This makes it possible to optimize the tightness and the depression generated at the outlet of the tube during the circulation of the air flow.
Selon une réalisation de l'invention, le bol comprend sur sa face avant une deuxième poignée de préhension. La mise en œuvre de cette deuxième poignée de préhension permet de manipuler convenablement le bol une fois extrait. Cela permet également une meilleure prise en main de l'aspirateur lors de nettoyage de surfaces rehaussées ; l'utilisateur peut en effet saisir avec une main la première poignée de préhension située à l'arrière de l'aspirateur et saisir avec l'autre main la deuxième poignée de préhension disposée à l'avant de l'aspirateur.According to one embodiment of the invention, the bowl comprises on its front face a second gripping handle.
