Description

Domaine techniqueTechnical field

La présente invention concerne le domaine des aspirateurs domestiques 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 domestic vacuum cleaners for vacuuming up dust and small-sized 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 domestique comporte de façon connue un dispositif d'aspiration comprenant :

  • un carter de moteur comprenant une ouverture de passage,
  • un moteur d'aspiration disposé dans le carter de moteur et configuré pour générer un flux d'aspiration au travers de l'ouverture de passage, et
  • un élément d'étanchéité aéraulique comprenant une première portion d'étanchéité annulaire configurée pour coopérer de manière étanche avec le carter de moteur, et une deuxième portion d'étanchéité annulaire configurée pour coopérer de manière étanche avec le moteur d'aspiration, l'élément d'étanchéité aéraulique étant configuré pour guider le flux d'aspiration depuis l'ouverture de passage jusqu'à une ouverture d'entrée d'air prévue sur le moteur d'aspiration.
A domestic vacuum cleaner comprises, in a known manner, a suction device comprising:
  • an engine housing comprising a passage opening,
  • a suction motor disposed in the motor housing and configured to generate a suction flow through the passage opening, and
  • an air sealing element comprising a first annular sealing portion configured to sealingly cooperate with the motor housing, and a second annular sealing portion configured to sealingly cooperate with the suction motor, the air sealing element being configured to guide the suction flow from the passage opening to an air inlet opening provided on the suction motor.

L'élément d'étanchéité aéraulique est en outre configuré pour assurer un découplage du moteur d'aspiration par rapport au carter de moteur, et ainsi pour limiter le transfert des vibrations générées par le moteur d'aspiration au carter de moteur.The air sealing element is further configured to provide decoupling of the suction motor from the motor housing, and thus to limit the transfer of vibrations generated by the suction motor to the motor housing.

Toutefois, afin d'assurer une étanchéité satisfaisante entre le carter de moteur et le moteur d'aspiration, il est nécessaire de réaliser l'élément d'étanchéité aéraulique en un matériau très élastique. Or, la sélection d'un matériau trop élastique pour réaliser l'élément d'étanchéité aéraulique est préjudiciable au découplage du moteur d'aspiration par rapport au carter de moteur.However, in order to ensure a satisfactory seal between the motor housing and the suction motor, it is necessary to make the air sealing element from a very elastic material. However, selecting a material that is too elastic to make the air sealing element is detrimental to the decoupling of the suction motor from the motor housing.

De ce fait, le bruit généré par l'aspirateur domestique précité est susceptible de nuire au confort d'un utilisateur.Therefore, the noise generated by the aforementioned domestic vacuum cleaner is likely to harm the comfort of a user.

WO2010/051930 divulgue un aspirateur comprenant un dispositif d'aspiration comprenant un moteur d'aspiration disposé dans un carter, un élément d'étanchéité aéraulique pour créer une étanchéité entre le carter et le moteur d'aspiration, des moyens d'amortissements qui en fonctionnement du moteur d'aspiration sont comprimés par la dépression créée à l'aspiration. WO2010/051930 discloses a vacuum cleaner comprising a suction device comprising a suction motor arranged in a housing, an air sealing element for creating a seal between the housing and the suction motor, damping means which, during operation of the suction motor, are compressed by the vacuum created during suction.

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 dispositif d'aspiration qui assure un découplage optimal du moteur d'aspiration par rapport au carter de moteur, tout en assurant une étanchéité optimale entre le carter de moteur et le moteur d'aspiration.The technical problem underlying the invention consists in particular in providing a suction device which ensures optimum decoupling of the suction motor from the motor housing, whilst ensuring optimum sealing between the motor housing and the suction motor.

A cet effet, la présente invention concerne un aspirateur domestique comportant un dispositif d'aspiration, comprenant un carter de moteur comportant un support et une ouverture de passage prévue sur le support ; un moteur d'aspiration disposé dans le carter de moteur et supporté par le support, le moteur d'aspiration comprenant une ouverture d'entrée d'air et étant configuré pour générer un flux d'aspiration au travers de l'ouverture de passage et de l'ouverture d'entrée d'air ; et un élément d'étanchéité aéraulique comportant une première portion d'étanchéité configurée pour coopérer de manière étanche avec le carter de moteur et une deuxième portion d'étanchéité configurée pour coopérer de manière étanche avec le moteur d'aspiration,

  • dans lequel le dispositif d'aspiration comporte en outre au moins un élément d'amortissement interposé entre le support et le moteur d'aspiration,
  • dans lequel l'au moins un élément d'amortissement est distinct de l'élément d'étanchéité aéraulique, et
  • dans lequel l'élément d'étanchéité aéraulique est annulaire, et l'au moins un élément d'amortissement est disposé à la périphérie de l'élément d'étanchéité aéraulique,
  • caractérisé en ce que l'au moins un élément d'amortissement est configuré pour supporter le poids du moteur d'aspiration et en ce que le dispositif d'aspiration est configuré de telle sorte que, lorsqu'un axe longitudinal du moteur d'aspiration est sensiblement vertical et l'ouverture d'entrée d'air est orientée vers le sol, le support et l'au moins un élément d'amortissement sont situés en-dessous du moteur d'aspiration.
To this end, the present invention relates to a domestic vacuum cleaner comprising a suction device, comprising a motor housing comprising a support and a passage opening provided on the support; a suction motor arranged in the motor housing and supported by the support, the suction motor comprising an air inlet opening and being configured to generate a suction flow through the passage opening and the air inlet opening; and an air sealing element comprising a first sealing portion configured to cooperate in a sealed manner with the motor housing and a second sealing portion configured to cooperate in a sealed manner with the suction motor,
  • wherein the suction device further comprises at least one damping element interposed between the support and the suction motor,
  • wherein the at least one damping element is distinct from the air sealing element, and
  • wherein the air sealing element is annular, and the at least one damping element is arranged at the periphery of the air sealing element,
  • characterized in that the at least one damping element is configured to support the weight of the suction motor and in that the suction device is configured such that, when a longitudinal axis of the suction motor is substantially vertical and the air inlet opening is oriented towards the ground, the support and the at least one damping element are located below the suction motor.

Une telle configuration de l'au moins un élément d'amortissement permet de dissocier la fonction d'étanchéité, qui est réalisée par l'élément d'étanchéité aéraulique, de la fonction découplage, qui est réalisée par l'au moins un élément d'amortissement, et donc de pouvoir utiliser des matériaux de duretés différentes pour fabriquer l'élément d'étanchéité aéraulique et l'au moins un élément d'amortissement. Un tel choix de matériaux permet par exemple de réaliser l'élément d'étanchéité aéraulique avec un matériau très élastique de manière à favoriser l'étanchéité entre le carter de moteur et le moteur d'aspiration, et de réaliser l'au moins un élément d'amortissement avec un matériau un peu plus dur de manière à favoriser l'amortissement des vibrations générées par le moteur d'aspiration.Such a configuration of the at least one damping element makes it possible to dissociate the sealing function, which is performed by the air sealing element, from the decoupling function, which is performed by the at least one damping element, and therefore to be able to use materials of different hardnesses to manufacture the air sealing element and the at least one damping element. Such a choice of materials makes it possible, for example, to produce the air sealing element with a very elastic material so as to promote sealing between the motor housing and the suction motor, and to produce the at least one damping element with a slightly harder material so as to promote damping of the vibrations generated by the suction motor.

Ainsi, en adaptant les matériaux constituant l'élément d'étanchéité aéraulique et l'au moins un élément d'amortissement, le dispositif d'aspiration selon la présente invention assure une étanchéité optimale entre le carter de moteur et le moteur d'aspiration, et une limitation optimale du transfert des vibrations générées par le moteur d'aspiration au carter de moteur.Thus, by adapting the materials constituting the air sealing element and the at least one damping element, the suction device according to the present invention ensures optimum sealing between the motor housing and the suction motor, and optimum limitation of the transfer of vibrations generated by the suction motor to the motor housing.

Par conséquent, le dispositif d'aspiration selon la présente invention assure un découplage amélioré du moteur d'aspiration par rapport au carter de moteur, tout en assurant une étanchéité optimale entre le carter de moteur et le moteur d'aspiration.Therefore, the suction device according to the present invention ensures improved decoupling of the suction motor from the motor housing, while ensuring optimum sealing between the motor housing and the suction motor.

Le dispositif d'aspiration peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison.The suction device may further have one or more of the following features, taken alone or in combination.
