Description

Domaine techniqueTechnical area

La présente invention concerne le domaine des conduits d'aspirateur, et en particulier des aspirateurs balais équipés de tels conduits d'aspirateur.The present invention relates to the field of vacuum cleaner ducts, and in particular stick vacuums equipped with such vacuum cleaner ducts.

Technique antérieurePrior art

Un aspirateur balai comprend de façon connue un corps d'aspirateur équipé d'une unité d'aspiration et d'une interface de manipulation, un suceur agencé pour être en contact avec un sol à nettoyer, et un conduit d'aspirateur reliant fluidiquement le corps d'aspirateur au suceur et définissant un passage d'écoulement d'air.A stick vacuum cleaner comprises in known manner a vacuum cleaner body equipped with a suction unit and a handling interface, a nozzle arranged to be in contact with a floor to be cleaned, and a vacuum cleaner duct fluidly connecting the vacuum cleaner body and defining an air flow passage.

Afin de faciliter le rangement de l'aspirateur balai ou un nettoyage avec l'aspirateur balai sous des meubles, le conduit d'aspirateur peut avantageusement comprendre :

  • une première partie rigide et une deuxième partie rigide, et
  • un dispositif d'articulation reliant les première et deuxième parties rigides entre elles, le dispositif d'articulation étant configuré pour permettre un pivotement de la première partie rigide par rapport à la deuxième partie rigide autour de l'axe de pivotement et entre une configuration alignée dans laquelle les première et deuxième parties rigides sont sensiblement alignées l'une par rapport à l'autre et une configuration pliée dans laquelle les première et deuxième parties rigides définissent entre elles un angle inférieur à 180°.
In order to facilitate the storage of the stick vacuum cleaner or cleaning with the stick vacuum cleaner under furniture, the vacuum cleaner duct can advantageously include:
  • a first rigid part and a second rigid part, and
  • an articulation device connecting the first and second rigid parts to each other, the articulation device being configured to allow pivoting of the first rigid part relative to the second rigid part around the pivot axis and between an aligned configuration in which the first and second rigid parts are substantially aligned with respect to each other and a folded configuration in which the first and second rigid parts define between them an angle less than 180 °.

Le suceur peut notamment être équipé d'une brosse rotative et d'un moteur électrique configuré pour entraîner en rotation la brosse rotative. A cet effet, il est connu d'équiper le conduit d'aspirateur de deux fils électriques qui sont configurés pour relier électriquement les bornes d'une batterie logée dans le corps d'aspirateur aux bornes du moteur électrique. Les deux fils électriques peuvent par exemple s'étendre dans un ou plusieurs passages de réception longitudinaux prévus dans le conduit d'aspirateur.The nozzle can in particular be equipped with a rotary brush and an electric motor configured to drive the rotary brush in rotation. To this end, it is known to equip the vacuum cleaner duct with two electric wires which are configured to electrically connect the terminals of a battery housed in the vacuum cleaner body to the terminals of the electric motor. The two electric wires can for example extend in one or more longitudinal receiving passages provided in the vacuum cleaner duct.

Toutefois, un tel agencement des fils électriques entraîne des efforts de tension et/ou de pincement importants dans les fils électriques, en particulier au niveau de l'articulation du conduit d'aspirateur, lors des différents pliages successifs du conduit d'aspirateur, ce qui peut entraîner un endommagement prématuré de la conductivité électrique entre le corps d'aspirateur et le suceur, et donc une dégradation des performances de l'aspirateur balai.However, such an arrangement of the electrical wires results in significant tension and / or pinching forces in the electrical wires, in particular at the articulation of the vacuum cleaner duct, during the various successive folds of the vacuum cleaner duct, which can lead to premature damage to the electrical conductivity between the vacuum cleaner body and the squeegee, and therefore a deterioration in the performance of the vacuum cleaner.

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 conduit d'aspirateur qui soit de structure simple et fiable.The technical problem underlying the invention consists in particular in providing a vacuum cleaner duct which is of simple and reliable structure.

A cet effet, la présente invention concerne un conduit d'aspirateur comprenant :

  • une première partie rigide et une deuxième partie rigide,
  • un dispositif d'articulation reliant les première et deuxième parties rigides entre elles, le dispositif d'articulation comportant un axe de pivotement et étant configuré pour permettre un pivotement de la première partie rigide par rapport à la deuxième partie rigide autour de l'axe de pivotement, et
  • au moins un fil électrique comportant une première partie de fil fixée à la première partie rigide et une deuxième partie de fil fixée à la deuxième partie rigide,
caractérisé en ce que l'au moins un fil électrique comporte une partie intermédiaire qui est située entre les première et deuxième parties de fil et qui forme une boucle autour de l'axe de pivotement.To this end, the present invention relates to a vacuum cleaner duct comprising:
  • a first rigid part and a second rigid part,
  • an articulation device connecting the first and second rigid parts together, the articulation device comprising a pivot axis and being configured to allow pivoting of the first rigid part relative to the second rigid part around the axis of pivoting, and
  • at least one electric wire comprising a first part of wire fixed to the first rigid part and a second part of wire fixed to the second rigid part,
characterized in that the at least one electric wire has an intermediate part which is situated between the first and second parts of wire and which forms a loop around the pivot axis.

Une telle configuration de l'au moins un fil électrique, et en particulier le fait que ce dernier s'étende autour de l'axe d'articulation de manière à former une boucle, permet de supprimer les efforts de tension et de pincement dans le fil électrique lors du pliage du conduit d'aspirateur.Such a configuration of the at least one electric wire, and in particular the fact that the latter extends around the axis of articulation so as to form a loop, makes it possible to eliminate the tension and pinching forces in the electric wire when folding the vacuum cleaner duct.

Par conséquent, lorsque le conduit d'aspirateur selon la présente invention équipe un aspirateur balai, le conduit d'aspirateur garantit la conductivité électrique entre un corps d'aspirateur et un suceur appartenant à l'aspirateur balai pendant toute la durée de vie de ce dernier.Consequently, when the vacuum cleaner duct according to the present invention equips a stick vacuum cleaner, the vacuum cleaner pipe guarantees the electrical conductivity between a vacuum cleaner body and a nozzle belonging to the stick vacuum cleaner. latest.
