Description

Domaine techniqueTechnical area

La présente invention concerne le domaine des aspirateurs permettant d'aspirer des poussières et des déchets de faible granulométrie présents sur une surface à nettoyer, qui peut par exemple être du carrelage, du parquet, du stratifié, de la moquette ou un tapis.The present invention relates to the field of vacuum cleaners making it possible to suck up dust and small-particle waste present on a surface to be cleaned, which can for example be tiles, parquet, laminate, carpet or a rug.

Etat de la techniqueState of the art

Un aspirateur, et plus particulièrement un aspirateur portatif, comporte de façon connue un conduit d'aspiration, un dispositif de séparation de déchets et un boîtier renfermant un moteur d'aspiration configuré pour générer un flux d'air au travers du conduit d'aspiration et du dispositif de séparation de déchets, le boîtier comprenant un circuit d'échappement d'air par lequel le flux d'air généré par le moteur d'aspiration est évacué vers l'extérieur du boîtier. De façon avantageuse, le circuit d'échappement d'air peut être équipé d'un filtre amovible.A vacuum cleaner, and more particularly a portable vacuum cleaner, comprises in known manner a suction duct, a waste separation device and a casing containing a suction motor configured to generate a flow of air through the suction duct and the waste separation device, the housing comprising an air exhaust circuit through which the air flow generated by the suction motor is evacuated to the outside of the housing. Advantageously, the air exhaust circuit can be equipped with a removable filter.

Le bruit généré lors du fonctionnement d'un tel aspirateur portatif peut toutefois s'avéré important, ce qui peut rendre l'utilisation d'un tel aspirateur portatif déplaisante.The noise generated during the operation of such a portable vacuum cleaner can however be significant, which can make the use of such a portable vacuum cleaner unpleasant.

CN206934037U divulgue un aspirateur portatif avec un moteur d'aspiration comportant un carter de moteur perforé pour échapper l'air. CN206934037U discloses a portable vacuum cleaner with a vacuum motor having a perforated motor housing to exhaust air.

Résumé de l'inventionSummary of the invention

La présente invention vise à remédier à tout ou partie de ces inconvénients.The present invention aims to remedy all or part of these drawbacks.

Le problème technique à la base de l'invention consiste notamment à fournir un aspirateur portatif qui soit de structure simple et économique, tout en réduisant sensiblement le bruit généré par l'aspirateur portatif lors de son utilisation.The technical problem underlying the invention consists in particular in providing a portable vacuum cleaner which is of simple and economical structure, while substantially reducing the noise generated by the portable vacuum cleaner during its use.

A cet effet, la présente invention concerne un aspirateur portatif comprenant un conduit d'aspiration, un dispositif de séparation de déchets et un boîtier renfermant un moteur d'aspiration configuré pour générer un flux d'air au travers du conduit d'aspiration et du dispositif de séparation de déchets, le boîtier comprenant un circuit d'échappement d'air par lequel le flux d'air généré par le moteur d'aspiration est évacué vers l'extérieur du boîtier, le circuit d'échappement d'air étant équipé d'un filtre qui est amovible, le circuit d'échappement d'air comportant une buse de diffusion d'air et le filtre présentant une forme de cartouche cylindrique et enveloppant latéralement la buse de diffusion d'air.To this end, the present invention relates to a portable vacuum cleaner comprising a suction duct, a waste separation device and a housing containing a suction motor configured to generate a flow of air through the suction duct and the waste separation device, the housing comprising an air exhaust circuit through which the flow of air generated by the suction motor is evacuated to the exterior of the housing, the air exhaust circuit being equipped with a filter which is removable, the air exhaust circuit comprising an air diffusion nozzle and the filter having the shape of a cylindrical cartridge and laterally enveloping the air diffusion nozzle.

Une telle configuration de la buse de diffusion d'air et du filtre assure une diffusion du flux d'air sortant du moteur d'aspiration vers une surface interne globalement cylindrique du filtre qui forme alors une paroi d'isolation phonique s'étendant autour de la buse de diffusion d'air.Such a configuration of the air diffusion nozzle and of the filter ensures diffusion of the flow of air leaving the suction motor towards a generally cylindrical internal surface of the filter which then forms a sound insulation wall extending around the air diffusion nozzle.

Ainsi, la configuration spécifique du filtre selon la présente invention, associée à la présence d'une buse de diffusant d'air en amont du filtre, réduit de manière significative le bruit généré par l'aspirateur portatif, ce qui rend l'utilisation de ce dernier bien plus agréable.Thus, the specific configuration of the filter according to the present invention, associated with the presence of an air diffuser nozzle upstream of the filter, significantly reduces the noise generated by the portable vacuum cleaner, which makes the use of the latter much nicer.

L'aspirateur portatif peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison.The portable vacuum cleaner may further have one or more of the following features, taken alone or in combination.

Selon un mode de réalisation de l'invention, le filtre comporte une partie de filtration qui est cylindrique et plissée, la partie de filtration enveloppant latéralement la buse de diffusion d'air. Une telle configuration du filtre améliore encore les performances d'atténuation acoustique du filtre, et réduit donc encore le bruit généré par l'aspirateur portatif.According to one embodiment of the invention, the filter comprises a filtration part which is cylindrical and pleated, the filtration part laterally enveloping the air diffusion nozzle. Such a configuration of the filter further improves the acoustic attenuation performance of the filter, and therefore further reduces the noise generated by the portable vacuum cleaner.

Selon l'invention, la buse de diffusion d'air présente une forme globalement cylindrique et comporte des ouvertures latérales, chacune des ouvertures latérales étant configurée pour diffuser une partie du flux d'air généré par le moteur d'aspiration vers le filtre.According to the invention, the air diffusion nozzle has a generally cylindrical shape and comprises side openings, each of the side openings being configured to diffuse part of the air flow generated by the suction motor towards the filter.

Selon l'invention, chacune des ouvertures latérales est configurée pour diffuser une partie du flux d'air généré par le moteur d'aspiration vers la partie de filtration du filtre, et plus particulièrement vers une surface périphérique interne de la partie de filtration.According to the invention, each of the side openings is configured to diffuse part of the air flow generated by the suction motor towards the filtration part of the filter, and more particularly towards an internal peripheral surface of the filtration part.

Selon l'invention, la buse de diffusion d'air comporte une chambre interne relié fluidiquement à un orifice de refoulement d'air du moteur d'aspiration, chacune des ouvertures latérales de la buse de diffusion d'air débouchant dans la chambre interne.According to the invention, the air diffusion nozzle comprises an internal chamber fluidly connected to an air discharge orifice of the suction motor, each of the side openings of the air diffusion nozzle opening into the internal chamber.

Selon l'invention, l'orifice de refoulement d'air du moteur d'aspiration débouche, par exemple axialement, dans la chambre interne de la buse de diffusion d'air.According to the invention, the air discharge orifice of the suction motor opens, for example axially, into the internal chamber of the air diffusion nozzle.

Selon un mode de réalisation de l'invention, chaque ouverture latérale est allongée et s'étend sensiblement parallèlement à l'axe longitudinal de la buse de diffusion d'air.According to one embodiment of the invention, each side opening is elongated and extends substantially parallel to the longitudinal axis of the air diffusion nozzle.

Selon un mode de réalisation de l'invention, la buse de diffusion d'air et le filtre sont disposés coaxialement.According to one embodiment of the invention, the air diffusion nozzle and the filter are arranged coaxially.

Selon un mode de réalisation de l'invention, les ouvertures latérales sont décalées angulairement les unes par rapport aux autres.According to one embodiment of the invention, the side openings are angularly offset from each other.

Selon un mode de réalisation de l'invention, les ouvertures latérales sont réparties, et avantageusement régulièrement réparties, autour de l'axe longitudinal de la buse de diffusion d'air.According to one embodiment of the invention, the side openings are distributed, and advantageously evenly distributed, around the longitudinal axis of the air diffusion nozzle.

Selon un mode de réalisation de l'invention, le boîtier et la buse de diffusion d'air délimitent une chambre de réception dans laquelle est reçu de manière amovible le filtre. De façon avantageuse, la chambre de réception est annulaire.According to one embodiment of the invention, the housing and the air diffusion nozzle delimit a receiving chamber in which the filter is removably received. Advantageously, the receiving chamber is annular.

Selon de l'invention, les ouvertures latérales de la buse de diffusion d'air débouchent dans la chambre de réception.According to the invention, the side openings of the air diffusion nozzle open into the receiving chamber.

Selon un mode de réalisation de l'invention, l'aspirateur portatif comporte un capot amovible qui est fixé de manière amovible au boîtier, le capot amovible étant configuré pour empêcher un accès au filtre lorsque le capot amovible est fixé au boîtier et pour permettre un accès au filtre lorsque le capot amovible est déposé. Ces dispositions permettent de pouvoir aisément accéder au filtre et de le retirer hors du boîtier en vue de maintenance, et notamment en vue de son nettoyage ou de son remplacement.According to one embodiment of the invention, the portable vacuum cleaner comprises a removable cover which is removably attached to the housing, the removable cover being configured to prevent access to the filter when the removable cover is attached to the housing and to allow a access to the filter when the removable cover is removed. These arrangements make it possible to easily access the filter and to remove it from the casing for maintenance purposes, and in particular for cleaning or replacement thereof.

Le filtre 26 présente une forme de cartouche cylindrique et enveloppe latéralement la buse de diffusion d'air 21. De façon avantageuse, la buse de diffusion d'air 21, le filtre 26 et le moteur d'aspiration 6 sont disposés coaxialement.The air exhaust circuit 19 is also equipped with a filter 26 which is removably mounted in the receiving chamber 22. The filter 26 has the shape of a cylindrical cartridge and laterally envelopes the air diffusion nozzle 21 Advantageously, the air diffusion nozzle 21, the filter 26 and the suction motor 6 are arranged coaxially.

Selon le mode de réalisation représenté sur les figures, le filtre 26 comporte une partie de filtration 27 qui est cylindrique et plissée, et qui enveloppe latéralement la buse de diffusion d'air 21, et plus particulièrement la surface latérale 25 de la buse de diffusion d'air 21 sur laquelle sont ménagées les ouvertures latérales 24.According to the embodiment shown in the figures, the filter 26 comprises a filtration part 27 which is cylindrical and pleated, and which laterally envelops the air diffusion nozzle 21, and more particularly the lateral surface 25 of the diffusion nozzle air vent 21 on which the side openings 24 are made.

Ainsi, chacune des ouvertures latérales 24 est configurée pour diffuser une partie du flux d'air généré par le moteur d'aspiration 6 vers la partie de filtration 27, et plus particulièrement vers une surface périphérique interne de la partie de filtration 27.Thus, each of the side openings 24 is configured to diffuse a part of the air flow generated by the suction motor 6 towards the filtration part 27, and more particularly towards an internal peripheral surface of the filtration part 27.

Le circuit d'échappement d'air 19 comprend en outre des ouvertures d'évacuation d'air 28 prévues sur une surface externe du boîtier 3 et à travers lesquelles le flux d'air généré par le moteur d'aspiration 6 est évacué vers l'extérieur du boîtier 3.The air exhaust circuit 19 further comprises air exhaust openings 28 provided on an outer surface of the casing 3 and through which the air flow generated by the suction motor 6 is exhausted to the exterior of the case 3.

L'aspirateur portatif 2 comporte également un capot amovible 29 qui est fixé de manière amovible au boîtier 3, et qui est configuré pour empêcher un accès au filtre 26 lorsque le capot amovible 29 est fixé au boîtier 3 et pour permettre un accès au filtre 26 lorsque le capot amovible 29 est déposé. Le capot amovible 29 est disposé sur une face arrière du boîtier 3 de l'aspirateur portatif 2 qui est située à l'opposé du conduit d'aspiration 18.

De façon avantageuse, les deux éléments de verrouillage 33 sont situés à l'opposé l'un de l'autre, et sont donc diamétralement opposés lorsque la partie de fermeture 32 présente une forme globalement circulaire.According to the embodiment shown in the figures, the closure part 32 extends substantially perpendicular to the longitudinal axis B of the suction motor 6, and each of the locking elements 33 extends substantially parallel to the longitudinal axis B of the suction motor 6. Advantageously, the two locking elements 33 are located opposite each other, and are therefore diametrically opposed when the closure part 32 has a generally circular shape.

Chaque élément de verrouillage 33 comporte une partie de verrouillage 33.1, telle qu'un ergot de verrouillage, et est élastiquement déformable entre une position de verrouillage dans laquelle la partie de verrouillage 33.1 est apte à coopérer avec le boîtier 3, et par exemple avec un logement de verrouillage prévu sur le boitier 3, de manière à verrouiller le capot amovible 27 sur le boîtier 3 et une position de libération dans laquelle la partie de verrouillage 33.1 est apte à libérer le boîtier 3 de manière à permettre une dépose du capot amovible 29.Each locking element 33 comprises a locking part 33.1, such as a locking lug, and is elastically deformable between a locking position in which the locking part 33.1 is capable of cooperating with the housing 3, and for example with a locking housing provided on the box 3, so as to lock the removable cover 27 on the box 3 and a release position in which the locking part 33.1 is able to release the box 3 so as to allow removal of the removable cover 29 .

Chaque élément de verrouillage 33 peut également comporter une partie d'appui 33.2, par exemple pourvue d'une empreinte, configurée de telle sorte que, lorsqu'un effort d'appui est exercé par un utilisateur sur la partie d'appui 33.2, l'élément de verrouillage 33 respectif est déformé élastiquement de la position de verrouillage à la position de libération.Each locking element 33 may also include a support part 33.2, for example provided with an imprint, configured so that, when a pressure force is exerted by a user on the support part 33.2, the The respective locking element 33 is elastically deformed from the locking position to the release position.

Selon le mode de réalisation représenté sur les figures, le filtre 26 est fixé de manière amovible sur le capot amovible 29. A cet effet, le capot amovible 29 comporte deux éléments d'immobilisation 34, tels que des pattes d'immobilisation, configurés pour immobiliser le filtre 26 sur le capot amovible 29. Chaque élément d'immobilisation 34 peut par exemple être situé sur un surface interne d'un élément de verrouillage 33 respectif.According to the embodiment shown in the figures, the filter 26 is removably fixed to the removable cover 29. To this end, the removable cover 29 comprises two immobilization elements 34, such as immobilization lugs, configured to immobilize the filter 26 on the removable cover 29.

Selon un mode de réalisation de l'invention, le filtre 26 est configuré pour être fixé sur le capot amovible 29 selon une direction de fixation D qui s'étend transversalement, et par exemple perpendiculairement, à l'axe longitudinal C du filtre 26.According to one embodiment of the invention, the filter 26 is configured to be fixed on the removable cover 29 along a fixing direction D which extends transversely, and for example perpendicularly, to the longitudinal axis C of the filter 26.

Le fonctionnement de l'aspirateur 2 va maintenant être décrit. Lorsque le moto-ventilateur 13 est alimenté électriquement, il établit une dépression notamment dans le dispositif de séparation de déchets 5 de telle sorte que de l'air et des déchets sont aspirés par le conduit d'aspiration 18. L'air chargé de déchets pénètre ensuite dans le récipient de stockage de déchets 7 via l'ouverture d'admission d'air 9 qui peut par exemple déboucher tangentiellement dans le récipient de stockage de déchets 7. L'air est ainsi mis en rotation et les déchets sont centrifugés vers l'extérieur et ces déchets sont collectés par le récipient de stockage de déchets 7.The operation of the vacuum cleaner 2 will now be described. When the motor-driven fan 13 is electrically powered, it establishes a depression in particular in the waste separation device 5 so that air and waste are sucked in through the suction duct 18. The air laden with waste then enters the waste storage container 7 via the air intake opening 9 which can for example emerge tangentially into the waste storage container 7. The air is thus set in rotation and the waste is centrifuged towards outside and this waste is collected by the waste storage container 7.

Le flux d'air s'écoule ensuite successivement à travers l'orifice de sortie d'air 11, la tubulure de liaison 16, et l'orifice d'entrée d'air 14 et l'orifice de refoulement d'air 15 du moteur d'aspiration 6. Puis, le flux d'air est diffusé radialement vers le filtre 26 par les ouvertures latérales 24, et s'écoule à travers la partie de filtration 27 avant de s'échapper hors du boîtier 3 au travers des ouvertures d'évacuation d'air 28.The air flow then flows successively through the air outlet orifice 11, the connecting pipe 16, and the air inlet orifice 14 and the air discharge orifice 15 of the suction motor 6. Then, the air flow is diffused radially towards the filter 26 through the side openings 24, and flows through the filtration part 27 before escaping out of the casing 3 through the openings exhaust vent 28.

Bien entendu, la présente invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention défini par les revendications.Of course, the present invention is in no way limited to the embodiment described and illustrated which has been given only by way of example. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention defined by the claims.
