La présente invention concerne le domaine des aspirateurs équipés d'une tête d'aspiration permettant d'aspirer les poussières et les déchets de faible granulométrie présents sur une surface à nettoyer.The present invention relates to the field of vacuum cleaners equipped with a suction head for sucking up dust and small particle size waste present on a surface to be cleaned.

Etat de la techniqueState of the art

Les aspirateurs équipés d'une tête d'aspiration sont bien connus sur le marché, ceux-ci permettant de nettoyer des surfaces par aspiration pour l'évacuation des poussières et des déchets de faible granulométrie reposant sur celles-ci. La surface à aspirer peut par exemple être du carrelage, du parquet, du stratifié, de la moquette ou un tapis.Vacuum cleaners equipped with a suction head are well known on the market, the latter making it possible to clean surfaces by suction for the removal of dust and small-grain waste based thereon. The surface to be vacuumed can, for example, be tiles, parquet, laminate, carpet or a rug.

Une tête d'aspiration comprend de façon connue un corps principal comportant une semelle munie d'une face inférieure et d'un orifice d'aspiration débouchant dans la face inférieure de la semelle. La face inférieure de la semelle est destinée à être positionnée de manière attenante à la surface à aspirer durant l'utilisation de la tête d'aspiration.A suction head comprises, in a known manner, a main body comprising a sole provided with a lower face and with a suction orifice opening into the lower face of the sole. The underside of the sole is intended to be positioned adjacent to the surface to be vacuumed during use of the vacuum head.

Afin d'améliorer les performances de nettoyage d'une tête d'aspiration, il est connu d'équiper cette dernière d'une unité de nettoyage comprenant :

  • une brosse rotative qui est mobile en rotation autour d'un axe de rotation et qui est montée de manière amovible dans un logement de réception délimité par le corps principal de la tête d'aspiration, et
  • un bouchon de fermeture qui est configuré pour fermer au moins partiellement une ouverture de passage prévue sur le corps principal et à travers laquelle la brosse rotative est apte à être introduite dans et retirée hors du logement de réception, la brosse rotative étant rotative par rapport au bouchon de fermeture.
In order to improve the cleaning performance of a suction head, it is known practice to equip the latter with a cleaning unit comprising:
  • a rotating brush which is movable in rotation about an axis of rotation and which is removably mounted in a receiving housing delimited by the main body of the suction head, and
  • a closure plug which is configured to at least partially close a passage opening provided on the main body and through which the rotating brush is adapted to be introduced into and withdrawn out of the receiving housing, the rotating brush being rotatable relative to the closing cap.

Afin de permettre une manipulation du bouchon de fermeture par un utilisateur, notamment lors d'un retrait de la brosse rotative en vue par exemple de son nettoyage, il est connu d'équiper le bouchon de fermeture de deux ailettes de préhension qui sont diamétralement opposées par rapport à l'axe de rotation de la brosse rotative et qui font saillie depuis une surface frontale du bouchon de fermeture.In order to allow manipulation of the closure plug by a user, in particular when the rotating brush is withdrawn for example for cleaning, it is known practice to equip the closure plug with two gripping fins which are diametrically opposed. relative to the axis of rotation of the rotating brush and which protrude from a front surface of the closure cap.

Or, une telle configuration du bouchon de fermeture augmente l'encombrement du bouchon de fermeture et donc de l'unité de nettoyage, et peut induire un déverrouillage intempestif du bouchon de fermeture lors par exemple d'un impact du bouchon de fermeture contre un obstacle.However, such a configuration of the closing cap increases the size of the closing cap and therefore of the cleaning unit, and can induce an untimely unlocking of the closing cap during, for example, an impact of the closing cap against an obstacle. .

Afin de limiter l'encombrement du bouchon de fermeture, il peut être envisagé de diminuer les dimensions des deux ailettes de préhension, ce qui rend cependant malaisé la manipulation du bouchon de fermeture pour certains utilisateurs.In order to limit the size of the closure cap, it can be envisaged to reduce the dimensions of the two gripping fins, which however makes it difficult to handle the closure cap for some users.

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 une unité de nettoyage pour tête d'aspiration assurant une manipulation aisée et ergonomique du bouchon de fermeture, tout en assurant un verrouillage fiable du bouchon de fermeture sur le corps principal de la tête d'aspiration.The technical problem underlying the invention consists in particular in providing a cleaning unit for a suction head ensuring easy and ergonomic handling of the closure cap, while ensuring reliable locking of the closure cap on the main body of the device. suction head.

A cet effet, la présente invention concerne une unité de nettoyage pour tête d'aspiration, comprenant :

  • une brosse rotative qui est mobile en rotation autour d'un axe de rotation et qui est configurée pour être montée de manière amovible dans un logement de réception délimité par un corps principal de la tête d'aspiration, et
  • un bouchon de fermeture qui est configuré pour fermer au moins partiellement une ouverture de passage prévue sur le corps principal et à travers laquelle la brosse rotative est apte à être introduite dans le logement de réception et retirée hors du logement de réception, la brosse rotative étant rotative par rapport au bouchon de fermeture.
To this end, the present invention relates to a cleaning unit for a suction head, comprising:
  • a rotating brush which is movable in rotation about an axis of rotation and which is configured to be removably mounted in a receiving housing delimited by a main body of the suction head, and
  • a closure plug which is configured to at least partially close a passage opening provided on the main body and through which the rotating brush is adapted to be introduced into the receiving housing and withdrawn from the receiving housing, the rotating brush being rotatable relative to the closure cap.

Le bouchon de fermeture comporte une poignée de préhension qui est mobile entre une position de repos et une position de préhension dans laquelle la poignée de préhension est configurée pour être saisie par un utilisateur de manière à pouvoir manipuler le bouchon de fermeture, et par exemple de manière à pouvoir retirer la brosse rotative hors du logement de réception lorsque la brosse rotative est montée dans le logement de réception.The closure cap has a grip handle which is movable between a rest position and a grip position in which the grip handle is configured to be gripped by a user so that it can be gripped. manipulate the closure cap, and for example so as to be able to withdraw the rotating brush from the receiving housing when the rotating brush is mounted in the receiving housing.

Une telle configuration de la poignée de préhension assure notamment un retrait aisé et ergonomique de la brosse rotative hors du logement de réception lorsque la poignée de préhension occupe la position de préhension, tout en limitant l'encombrement du bouchon de fermeture et donc de l'unité de nettoyage sur la tête d'aspiration, lorsque la poignée de préhension occupe la position de repos. De plus, une telle configuration de la poignée de préhension, et en particulier le fait que la poignée de préhension occupe la position de repos en conditions normales d'utilisation de la tête d'aspiration, limite considérablement les risques de déverrouillage intempestif du bouchon de fermeture.Such a configuration of the gripping handle ensures in particular an easy and ergonomic removal of the rotating brush from the receiving housing when the gripping handle occupies the gripping position, while limiting the size of the closure cap and therefore of the cleaning unit on the suction head, when the gripping handle is in the rest position. In addition, such a configuration of the gripping handle, and in particular the fact that the gripping handle occupies the rest position in normal conditions of use of the suction head, considerably limits the risks of inadvertent unlocking of the suction head. closing.

L'unité de nettoyage peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison.The cleaning unit may further have one or more of the following characteristics, taken alone or in combination.

Selon un mode de réalisation de l'invention, la poignée de préhension est configurée pour délimiter, lorsque la poignée de préhension occupe la position de préhension, au moins partiellement un passage de préhension apte à recevoir au moins un doigt d'un utilisateur.According to one embodiment of the invention, the gripping handle is configured to delimit, when the gripping handle occupies the gripping position, at least partially a gripping passage capable of receiving at least one finger of a user.

Selon un mode de réalisation de l'invention, la poignée de préhension s'étend sensiblement dans un plan de repos lorsque la poignée de préhension occupe la position de repos, le plan de repos s'étendant transversalement, et par exemple sensiblement perpendiculairement, à l'axe de rotation de la brosse rotative.According to one embodiment of the invention, the gripping handle extends substantially in a rest plane when the gripping handle occupies the rest position, the rest plane extending transversely, and for example substantially perpendicularly, to the axis of rotation of the rotating brush.

Selon un mode de réalisation de l'invention, la poignée de préhension s'étend sensiblement dans un plan de préhension lorsque la poignée de préhension occupe la position de préhension, le plan de préhension s'étendant sensiblement parallèlement à l'axe de rotation de la brosse rotative.According to one embodiment of the invention, the gripping handle extends substantially in a gripping plane when the gripping handle occupies the gripping position, the gripping plane extending substantially parallel to the axis of rotation of the rotating brush.

Selon un mode de réalisation de l'invention, dans la position de repos de la poignée de préhension, la poignée de préhension est logée dans un logement de poigné formé par une cavité du bouchon de fermeture.According to one embodiment of the invention, in the rest position of the gripping handle, the gripping handle is housed in a handle housing formed by a cavity of the closing cap.

Selon un mode de réalisation de l'invention, dans la position de repos de la poignée de préhension, la poignée de préhension est logée dans un logement de poigné formé par une cavité du bouchon de fermeture et est arrangée pour sensiblement affleurer ou être en retrait d'une surface extérieure du bouchon de fermeture. Ladite surface extérieure entoure la cavité du bouchon. En d'autres termes, dans la position de repos la poignée de préhension est logée dans une cavité du bouchon de fermeture et est arrangée pour ne pas faire saillie, ou que très légèrement, au-delà de la surface extérieure du bouchon de fermeture qui entoure la cavité du bouchon de fermeture. En effet, du fait des tolérances d'assemblage et jeux de fonctionnement, dans la position de repos de la poignée de préhension, la poignée de préhension pourrait être légèrement en saillie, de l'ordre de quelques dixièmes de millimètres jusqu'à environ 1 mm, au-delà de la surface extérieure du bouchon de fermeture qui entoure la cavité du bouchon de fermeture. La terminologie « sensiblement affleurante » couvre donc une saillie inférieure à 1mm de la poignée de préhension en position de repos par rapport à la surface extérieure du bouchon de fermeture qui entoure la cavité du bouchon.According to one embodiment of the invention, in the rest position of the gripping handle, the gripping handle is housed in a handle housing formed by a cavity of the closure plug and is arranged to be substantially flush with or recessed. an outer surface of the closure cap. Said outer surface surrounds the cavity of the plug. In other words, in the rest position the grip handle is housed in a cavity of the closure cap and is arranged not to protrude, or only very slightly, beyond the outer surface of the closure cap which surrounds the cavity of the closure cap. Indeed, due to assembly tolerances and operating clearances, in the rest position of the gripping handle, the gripping handle could be slightly protruding, of the order of a few tenths of a millimeter up to approximately 1. mm, beyond the outer surface of the closure cap which surrounds the cavity of the closure cap. The terminology “substantially flush” therefore covers a projection of less than 1 mm from the gripping handle in the rest position relative to the outer surface of the closure cap which surrounds the cavity of the cap.

Ainsi en position de repos, la poignée de préhension est discrète. Cette construction limite le risque d'accrochage inopiné de la poignée lorsque la tête d'aspiration en déplacement sur le sol à aspirer.Thus in the rest position, the gripping handle is discreet. This construction limits the risk of the handle catching unexpectedly when the suction head moving on the floor to be sucked.

Dans une variante au mode de réalisation juste précité, dans la position de repos de la poignée de préhension, la poignée de préhension est logée dans un logement de poigné formé par une cavité du bouchon de fermeture et est arrangée pour sensiblement affleurer ou être en retrait d'une surface extérieure du bouchon de fermeture qui entoure la cavité du bouchon de fermeture, à l'exception d'une saillie de préhension de la poignée de préhension qui est configurée pour être saisie par un utilisateur lorsque la poignée de préhension occupe la position de repos de manière à pourvoir déplacer la poignée de préhension de la position de repos à la position de préhension.In a variant of the embodiment just mentioned above, in the rest position of the gripping handle, the gripping handle is housed in a handle housing formed by a cavity of the closure cap and is arranged to be substantially flush with or recessed. an exterior surface of the closure plug which surrounds the cavity of the closure plug, except for a gripping protrusion of the grip handle which is configured to be gripped by a user when the grip handle occupies the position rest so as to be able to move the gripping handle from the rest position to the gripping position.

Selon un mode de réalisation de l'invention, la poignée de préhension est montée pivotante entre la position de repos et la position de préhension autour d'un axe de pivotement.According to one embodiment of the invention, the gripping handle is pivotally mounted between the rest position and the gripping position about a pivot axis.

Selon un mode de réalisation de l'invention, l'axe de pivotement de la poignée de préhension est sensiblement perpendiculaire à l'axe de rotation de la brosse rotative.According to one embodiment of the invention, the pivot axis of the gripping handle is substantially perpendicular to the axis of rotation of the rotary brush.

Une telle configuration du bouchon de fermeture garantit un verrouillage aisé et ergonomique du corps de bouchon sur le corps principal de la tête d'aspiration. En outre, une telle configuration du bouchon de fermeture assure un maintien efficace du corps de bouchon dans l'ouverture de passage et donc de la brosse rotative dans le logement de réception, et limite sensiblement la génération de vibrations par la brosse rotative lors de la rotation de cette dernière. De ce fait, l'unité de nettoyage selon la présente invention limite grandement le transfert de vibrations de la brosse rotative au corps principal de la tête d'aspiration, et assure un confort d'utilisation accru pour un utilisateur.Such a configuration of the closure cap guarantees easy and ergonomic locking of the cap body on the main body of the suction head. In addition, such a configuration of the closure cap ensures effective retention of the cap body in the passage opening and therefore of the rotating brush in the receiving housing, and substantially limits the generation of vibrations by the rotating brush during the rotation of the latter. Therefore, the cleaning unit according to the present invention greatly limits the transfer of vibrations from the rotating brush to the main body of the suction head, and provides increased convenience for a user.
