Description

Domaine techniqueTechnical area

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 household vacuum cleaners making it possible to suck up dust and waste of small particle size present on a surface to be cleaned, which may for example be tiles, parquet, laminate, carpet or a carpet.

Etat de la techniqueState of the art

Un aspirateur domestique comporte de façon connue un dispositif d'aspiration comprenant :

  • un carter de moteur,
  • un moteur d'aspiration disposé dans le carter de moteur et configuré pour générer un flux d'aspiration,
  • 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, et
  • un système de suspension configuré pour supporter le moteur d'aspiration par rapport au carter de moteur, le système de suspension comportant par exemple une pluralité d'éléments d'amortissement disposés autour du moteur d'aspiration et configurés pour coopérer avec le carter de moteur.
A domestic vacuum cleaner comprises in known manner a suction device comprising:
  • an engine casing,
  • a suction motor disposed in the motor housing and configured to generate a suction flow,
  • an aeraulic sealing element comprising a first annular sealing portion configured to cooperate in a sealed manner with the motor housing, and a second annular sealing portion configured to cooperate in a sealed manner with the suction motor, and
  • a suspension system configured to support the suction motor relative to the motor housing, the suspension system comprising for example a plurality of damping elements disposed around the suction motor and configured to cooperate with the motor housing .

Toutefois, le poids important du moteur d'aspiration entraîne une compression des éléments d'amortissement disposés sous le moteur d'aspiration et un étirage des éléments d'amortissement disposés au-dessus du moteur d'aspiration. Par conséquent, le poids important du moteur d'aspiration engendre un décentrage du moteur d'aspiration et ainsi une dissymétrie axiale des contraintes appliquées au niveau de l'élément d'étanchéité aéraulique et au niveau du système de suspension, ce qui nuit au découplage du moteur d'aspiration par rapport au carter de moteur de l'aspirateur. De ce fait, le bruit généré par un tel aspirateur domestiques est susceptible d'augmenter de manière significative dans le temps.However, the heavy weight of the suction motor causes compression of the damping elements arranged under the suction motor and a stretching of the damping elements disposed above the suction motor. Consequently, the significant weight of the suction motor generates an off-centering of the suction motor and thus an axial asymmetry of the stresses applied at the level of the aeraulic sealing element and at the suspension system, which impairs the decoupling of the vacuum motor from the vacuum motor housing. Therefore, the noise generated by such a household vacuum cleaner is likely to increase significantly over time.

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.

L'objectif de l'invention consiste notamment à fournir un dispositif d'aspiration qui assure un découplage optimal du moteur d'aspiration par rapport au boîtier de l'aspirateur, tout en limitant les coûts de fabrication du dispositif d'aspiration.The objective of the invention consists in particular in providing a suction device which ensures optimum decoupling of the suction motor from the housing of the vacuum cleaner, while limiting the manufacturing costs of the suction device.

A cet effet, la présente invention concerne un dispositif d'aspiration pour aspirateur domestique, comprenant :

  • un carter de moteur,
  • un moteur d'aspiration disposé dans le carter de moteur et configuré pour générer un flux d'aspiration,
  • 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, et
  • un système de suspension configuré pour supporter le moteur d'aspiration en particulier par rapport au carter de moteur,
caractérisé en ce que le système de suspension comporte une pluralité d'éléments d'amortissement répartis autour du moteur d'aspiration, chaque élément d'amortissement présentant une section transversale globalement en forme de S, et en ce que le système de suspension comporte en outre au moins un ressort de compensation configuré pour compenser le poids du moteur d'aspiration.To this end, the present invention relates to a suction device for a household vacuum cleaner, comprising:
  • an engine casing,
  • a suction motor disposed in the motor housing and configured to generate a suction flow,
  • an aeraulic sealing element comprising a first annular sealing portion configured to cooperate in a sealed manner with the motor housing, and a second annular sealing portion configured to cooperate in a sealed manner with the suction motor, and
  • a suspension system configured to support the vacuum motor by particular in relation to the engine casing,
characterized in that the suspension system comprises a plurality of damping elements distributed around the suction motor, each damping element having a generally S-shaped cross section, and in that the suspension system comprises in in addition to at least one compensation spring configured to compensate for the weight of the vacuum motor.

Une telle configuration des éléments d'amortissement permet d'utiliser des éléments d'amortissement très souples et donc de limiter le transfert des vibrations générées par le moteur d'aspiration au boîtier de l'aspirateur, et ainsi d'assurer un découplage amélioré du moteur d'aspiration par rapport au boîtier de l'aspirateur. En particulier, la forme en S des éléments d'amortissement assure une grande souplesse à ces derniers principalement dans une direction radiale et dans une direction tangentielle par rapport à l'axe longitudinal du moteur d'aspiration, ce qui permet de limiter grandement le transfert des vibrations générées par le moteur d'aspiration au boîtier de l'aspirateur domestique.Such a configuration of the damping elements makes it possible to use very flexible damping elements and therefore to limit the transfer of the vibrations generated by the suction motor to the vacuum cleaner housing, and thus to ensure improved decoupling of the vacuum cleaner. vacuum motor relative to the vacuum cleaner housing. In particular, the S-shape of the damping elements ensures great flexibility to the latter mainly in a radial direction and in a tangential direction with respect to the longitudinal axis of the suction motor, which makes it possible to greatly limit the transfer. vibrations generated by the vacuum motor to the housing of the household vacuum cleaner.

En outre, la présence du ressort de compensation permet de maintenir le moteur d'aspiration en « lévitation » de telle sorte que les éléments d'amortissement puissent tous travailler sensiblement dans les mêmes conditions et donc assurer un découplage optimal du moteur d'aspiration par rapport au boîtier de l'aspirateur.In addition, the presence of the compensation spring makes it possible to keep the suction motor in "levitation" so that the damping elements can all work in substantially the same conditions and therefore ensure optimum decoupling of the suction motor by compared to the vacuum cleaner housing.

De plus, la présence du ressort de compensation permet d'utiliser des éléments d'amortissement présentant une grande souplesse sans que cela ne nuise au découplage du moteur d'aspiration par rapport au boîtier de l'aspirateur.In addition, the presence of the compensation spring makes it possible to use damping elements exhibiting great flexibility without this prejudicing the decoupling of the suction motor from the housing of the vacuum cleaner.

Par conséquent, le dispositif d'aspiration selon la présente invention assure un découplage optimal du moteur d'aspiration par rapport au boîtier de l'aspirateur, tout en limitant les coûts de fabrication du dispositif d'aspiration.Consequently, the suction device according to the present invention ensures optimum decoupling of the suction motor from the housing of the vacuum cleaner, while limiting the manufacturing costs of the suction device.
