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 vacuum up small particle size dust and waste present on a surface to be cleaned, which may 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 dispositif de séparation de déchets qui comporte un orifice de sortie d'air, un dispositif d'aspiration qui comporte un orifice d'entrée d'air et un moto-ventilateur, et une tubulure de liaison reliant fluidiquement l'orifice d'entrée d'air du dispositif d'aspiration à l'orifice de sortie d'air du dispositif de séparation de déchets. Le moto-ventilateur est plus particulièrement configuré pour générer un flux d'air au travers de l'orifice de sortie d'air, de la tubulure de liaison et de l'orifice d'entrée d'air.A vacuum cleaner, and more particularly a portable vacuum cleaner, comprises in a known manner a waste separation device which comprises an air outlet orifice, a suction device which comprises an air inlet orifice and a motorized fan , and a connecting tube fluidly connecting the air inlet port of the suction device to the air outlet port of the waste separation device. The motorized fan is more particularly configured to generate an air flow through the air outlet orifice, the connecting tube and the air inlet orifice.

Dans un tel aspirateur, le dispositif de séparation de déchets s'étend généralement sensiblement perpendiculairement à l'axe d'extension du moto-ventilateur, et l'extrémité de la tubulure de liaison qui est orientée vers le dispositif de séparation de déchets présente généralement une section de passage sensiblement supérieure à la section de passage de l'orifice de sortie d'air du dispositif de séparation de déchets.In such a vacuum cleaner, the waste separation device generally extends substantially perpendicular to the axis of extension of the motorized fan, and the end of the connecting tube which is oriented towards the waste separation device generally presents a passage section substantially greater than the passage section of the air outlet orifice of the waste separation device.

Un tel agencement de l'aspirateur génère d'importantes turbulences au sein de la tubulure de liaison lors de l'écoulement dans cette dernière du flux d'air généré par le moto-ventilateur, et induit donc des pertes de charge élevées dans la tubulure de liaison. Or, ces pertes de charges élevées sont très préjudiciables pour les performances aérauliques de l'aspirateur.Such an arrangement of the vacuum cleaner generates significant turbulence within the connecting pipe during the flow in the latter of the air flow generated by the motorized fan, and therefore induces high pressure losses in the pipe. link. However, these high pressure losses are very detrimental to the aeraulic performance of the vacuum cleaner.

EP 3 409 159 A2 présente une tubulure de liaison entre une entrée d'air du dispositif d'aspiration et un orifice de sortie d'air du dispositif de séparation de déchets. EP 3 409 159 A2 has a connecting tube between an air inlet of the suction device and an air outlet orifice of the waste separation device.

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 qui soit de structure simple et économique, tout en ayant des performances aérauliques améliorées.The technical problem underlying the invention consists in particular of providing a vacuum cleaner which is simple and economical in structure, while having improved aeraulic performance.

A cet effet, la présente invention concerne un aspirateur comprenant un dispositif de séparation de déchets qui comporte un orifice de sortie d'air, un dispositif d'aspiration qui comporte un orifice d'entrée d'air et un moto-ventilateur, et une tubulure de liaison reliant fluidiquement l'orifice d'entrée d'air du dispositif d'aspiration à l'orifice de sortie d'air du dispositif de séparation de déchets, le moto-ventilateur étant configuré pour générer un flux d'air au travers de l'orifice de sortie d'air, de la tubulure de liaison et de l'orifice d'entrée d'air, caractérisé en ce que la tubulure de liaison est coudée et évolue de manière continue de l'orifice de sortie d'air du dispositif de séparation de déchets jusqu'à l'orifice d'entrée d'air du dispositif d'aspiration.For this purpose, the present invention relates to a vacuum cleaner comprising a waste separation device which comprises an air outlet orifice, a suction device which comprises an air inlet orifice and a motorized fan, and a connecting tube fluidly connecting the air inlet orifice of the suction device to the air outlet orifice of the waste separation device, the motorized fan being configured to generate an air flow through of the air outlet orifice, the connecting pipe and the air inlet orifice, characterized in that the connecting pipe is bent and evolves continuously from the outlet orifice of air from the waste separation device to the air inlet of the suction device.

Une telle configuration de la tubulure de liaison limite les changements de section de passage brusques rencontrés par le flux d'air généré par le moto-ventilateur lors de son écoulement entre le dispositif de séparation de déchets et le dispositif d'aspiration, et diminue donc grandement les pertes de charge générées notamment au sein de la tubulure de liaison, ce qui améliore sensiblement les performances aérauliques de l'aspirateur selon la présente invention.Such a configuration of the connecting pipe limits the sudden changes in passage section encountered by the air flow generated by the motorized fan during its flow between the waste separation device and the suction device, and therefore reduces greatly the pressure losses generated in particular within the connecting tubing, which significantly improves the aeraulic performance of the vacuum cleaner according to the present invention.

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

Selon un mode de réalisation de l'invention, la tubulure de liaison présente une section de passage qui évolue de manière continue de l'orifice de sortie d'air du dispositif de séparation de déchets jusqu'à l'orifice d'entrée d'air du dispositif d'aspiration. Ces dispositions assurent une continuité dans les sections de passage rencontrées par le flux d'air lors de son écoulement du dispositif de séparation de déchets jusqu'au dispositif d'aspiration, ce qui réduit encore les pertes de charge générées au sein de la tubulure de liaison.According to one embodiment of the invention, the connecting pipe has a passage section which evolves continuously from the air outlet orifice of the waste separation device to the inlet orifice of air from the suction device. These arrangements ensure continuity in the passage sections encountered by the air flow as it flows from the waste separation device to the suction device, which further reduces the pressure losses generated within the waste pipe. connection.

Selon un mode de réalisation de l'invention, l'orifice de sortie d'air du dispositif de séparation de déchets et l'orifice d'entrée d'air du dispositif d'aspiration présentent des sections de passage différentes.According to one embodiment of the invention, the air outlet orifice of the device waste separation and the air inlet of the suction device have different passage sections.

Selon un mode de réalisation de l'invention, une section de passage de l'orifice de sortie d'air du dispositif de séparation de déchets est supérieure à une section de passage de l'orifice d'entrée d'air du dispositif d'aspiration.According to one embodiment of the invention, a passage section of the air outlet orifice of the waste separation device is greater than a passage section of the air inlet orifice of the waste separation device. suction.

Selon un mode de réalisation de l'invention, l'aspirateur comporte une grille de protection qui est située en amont du moto-ventilateur de manière à empêcher un accès au moto-ventilateur.According to one embodiment of the invention, the vacuum cleaner comprises a protective grille which is located upstream of the motorized fan so as to prevent access to the motorized fan.

Selon un mode de réalisation de l'invention, la grille de protection est intégrée à la tubulure de liaison. Ces dispositions permettent d'éloigner la grille de protection de l'orifice d'entrée d'air du dispositif d'aspiration, et en particulier de la positionner à un endroit où la section de passage pour le flux d'air est plus grande, et ce afin de réduire encore les pertes de charge du fait que la vitesse de flux d'air à cet endroit est plus faible.According to one embodiment of the invention, the protective grid is integrated into the connecting pipe. These arrangements make it possible to move the protective grille away from the air inlet orifice of the suction device, and in particular to position it in a location where the passage section for the air flow is larger, in order to further reduce pressure losses due to the fact that the air flow speed at this location is lower.

Selon un mode de réalisation de l'invention, la grille de protection est intégrée au carter de moteur.According to one embodiment of the invention, the protective grid is integrated into the motor casing.

Selon un mode de réalisation de l'invention, la grille de protection est située au niveau de l'orifice d'entrée d'air du dispositif d'aspiration.According to one embodiment of the invention, the protective grid is located at the level of the air inlet port of the suction device.

De façon avantageuse, l'orifice de sortie d'air 11 du dispositif de séparation de déchets 5 et l'orifice d'entrée d'air 14 du dispositif d'aspiration 6 présentent des sections de passage différentes. Selon le mode de réalisation représenté sur les figures 1 à 7, la section de passage de l'orifice de sortie d'air 11 est supérieure à la section de passage de l'orifice d'entrée d'air 14.As shown on the Figure 6 , the suction device 6 comprises an air inlet orifice 14 and an air discharge orifice 15 which are advantageously provided on the motor casing 12.

Selon le mode de réalisation représenté sur les figures 1 à 7, la tubulure de liaison 16 comporte une partie de montage 17 qui s'étend autour de la première extrémité 16.1 et qui est fixée au corps principal 3, et également une partie de fixation 18 qui s'étend autour de la deuxième extrémité 16.2 et qui est fixée au carter de moteur 12 du dispositif d'aspiration 6.According to the embodiment shown on the figures 1 to 7 , the connecting tube 16 comprises a mounting part 17 which extends around the first end 16.1 and which is fixed to the main body 3, and also a fixing part 18 which extends around the second end 16.2 and which is fixed to the motor housing 12 of the suction device 6.

L'aspirateur 2 comprend également une grille de protection 19 qui est située en amont du moto-ventilateur 13 de manière à empêcher un accès à un utilisateur aux parties actives du moto-ventilateur 13, notamment lorsque le dispositif de séparation de déchets 5 est retiré. Selon le mode de réalisation représenté sur les figures 1 à 7, la grille de protection 19 est intégrée au carter de moteur 12, et est avantageusement située au niveau de l'orifice d'entrée d'air 14 du dispositif d'aspiration 6.The vacuum cleaner 2 also includes a protective grid 19 which is located upstream of the motorized fan 13 so as to prevent access by a user to the active parts of the motorized fan 13, in particular when the waste separation device 5 is removed . According to the embodiment shown on the figures 1 to 7 , the protective grid 19 is integrated into the motor casing 12, and is advantageously located at the level of the air inlet orifice 14 of the suction device 6.

Le corps principal 3 comporte en outre un conduit d'aspiration d'air 21 auquel est relié fluidiquement l'ouverture d'admission d'air 9 du dispositif de séparation de déchets 5, et un conduit d'évacuation d'air 22 qui relie fluidiquement l'orifice de refoulement d'air 15 du dispositif d'aspiration 6 à des ouvertures d'évacuation d'air 23 prévues sur le corps principal 3.The main body 3 further comprises an air suction conduit 21 to which the air intake opening 9 of the waste separation device 5 is fluidly connected, and an air exhaust conduit 22 which connects fluidly the air discharge orifice 15 of the suction device 6 to air evacuation openings 23 provided on the main body 3.

Le flux d'air généré par le moto-ventilateur 13 est rejeté vers l'extérieur de l'aspirateur 2 via le conduit d'évacuation d'air 22 et les ouvertures d'évacuation d'air 23.The motorized fan 13 is more particularly configured to generate an air flow through the air suction duct 21, the air outlet orifice 11, the connecting tube 16 and the orifice air inlet 14. The air flow generated by the motorized fan 13 is rejected towards the outside of the vacuum cleaner 2 via the air exhaust duct 22 and the air exhaust openings 23.

Selon le mode de réalisation représenté sur les figures 1 à 7, le conduit d'évacuation d'air 22 comporte un élément de guidage de flux 24 qui est fixé au carter de moteur 12 et dans lequel débouche l'orifice de refoulement d'air 15 du dispositif d'aspiration 6. L'élément de guidage de flux 24 est plus particulièrement configuré pour canaliser et guider le flux d'air sortant de l'orifice de refoulement d'air 15 vers les ouvertures d'évacuation d'air 23.According to the embodiment shown on the figures 1 to 7 , the air exhaust duct 22 comprises a flow guide element 24 which is fixed to the motor casing 12 and into which the air discharge orifice 15 of the suction device 6 opens. flow guidance 24 is more particularly configured to channel and guide the air flow leaving the air delivery orifice 15 towards the air exhaust openings 23.

De façon avantageuse, l'élément de guidage de flux 24 comporte deux parois latérales 25.1, 25.2 et une paroi de guidage 26 qui relie entre elles les deux parois latérales 25.1, 25.2.

The guide wall 26 is curved and is located opposite the air discharge orifice 15.

L'élément de guidage de flux 24 comporte plus particulièrement une ouverture de sortie 27 qui est orientée sensiblement perpendiculairement par rapport au deuxième axe d'extension B du moto-ventilateur 13 et vers les ouvertures d'évacuation d'air 23. L'élément de guidage de flux 24 peut éventuellement comporter une pluralité d'ailettes de guidage 28 prévues sur une surface intérieure de la paroi de guidage 26.The flow guide element 24 more particularly comprises an outlet opening 27 which is oriented substantially perpendicular to the second extension axis B of the motorized fan 13 and towards the air exhaust openings 23. The flow guide element 24 may optionally comprise a plurality of guide fins 28 provided on an interior surface of the wall guide 26.

Le dispositif d'aspiration 6, la tubulure de liaison 16 et l'élément de guidage de flux 24 forment avantageusement un sous-ensemble qui peut être assemblé préalablement à sa fixation au corps principal 3.The suction device 6, the connecting tube 16 and the flow guide element 24 advantageously form a subassembly which can be assembled prior to its attachment to the main body 3.

Selon le mode de réalisation représenté sur les figures 1 à 7, l'aspirateur 2 comporte en outre un élément d'absorption acoustique 29 positionné dans le conduit d'évacuation d'air 22. L'élément d'absorption acoustique 29 peut être positionné en aval de l'élément de guidage de flux 24 ou encore dans l'élément de guidage de flux 24. L'élément d'absorption acoustique 29 est avantageusement en matériau poreux, et peut par exemple être une mousse acoustique.According to the embodiment shown on the figures 1 to 7 , the vacuum cleaner 2 further comprises a sound absorption element 29 positioned in the air exhaust duct 22. The sound absorption element 29 can be positioned downstream of the flow guide element 24 or still in the flow guide element 24. The sound absorption element 29 is advantageously made of porous material, and can for example be an acoustic foam.

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 d'air 21. 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 motorized 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 by the air suction conduit 21. The air loaded with waste then enters the waste storage container 7 via the air intake opening 9 which can for example open tangentially into the waste storage container 7. The air is thus rotated and the waste are centrifuged outwards 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 du dispositif d'aspiration 6, et ce sans rencontrer de changement de section brusque du fait de la configuration spécifique de la tubulure de liaison 16. Une telle configuration de la tubulure de liaison réduit ainsi sensiblement les pertes de charge générées au sein de la tubulure de liaison 16, ce qui améliore les performances aérauliques de l'aspirateur 2.The air flow then flows successively through the air outlet orifice 11, the connecting tube 16 and the air inlet orifice 14 of the suction device 6, without encountering any sudden change in section due to the specific configuration of the connecting pipe 16. Such a configuration of the connecting pipe thus significantly reduces the pressure losses generated within the connecting pipe 16, which improves the aeraulic performance of the vacuum cleaner 2.

Puis, le flux d'air s'écoule à travers l'orifice de refoulement d'air 15 et le long du conduit d'évacuation d'air 22 avant de s'échapper au travers de l'élément d'absorption acoustique 29 en direction des ouvertures d'évacuation 23. Le fait que le conduit d'évacuation d'air 22 soit en partie formé par l'élément de guidage de flux 24 réduit de manière sensible les pertes de charge générées en aval du dispositif d'aspiration 6, ce qui améliore encore les performances aérauliques de l'aspirateur 2.Then, the air flow flows through the air discharge port 15 and along the air exhaust duct 22 before escaping through the sound absorption element 29 in direction of the evacuation openings 23. The fact that the air evacuation duct 22 is partly formed by the flow guide element 24 significantly reduces the pressure losses generated downstream of the suction device 6 , which further improves the aeraulic performance of the vacuum cleaner 2.

Les figures 8 et 9 représentent un aspirateur selon un deuxième mode de réalisation de l'invention qui diffère de celui représenté sur les figures 1 à 7 essentiellement en ce que la grille de protection 19 est intégrée à la tubulure de liaison 16 et est située à proximité de la deuxième extrémité 16.2 de la tubulure de liaison 16.THE figures 8 And 9 represent a vacuum cleaner according to a second embodiment of the invention which differs from that represented on the figures 1 to 7 essentially in that the protective grid 19 is integrated into the connecting tube 16 and is located near the second end 16.2 of the connecting tube 16.

Bien entendu, la présente invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemples. 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.Of course, the present invention is in no way limited to the embodiments described and illustrated which have been given only by way of examples. Modifications remain possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
