Title (EN) VACUUM CLEANER NOZZLE
(FR) BUSE POUR ASPIRATEUR
Abstract:
(EN) The present invention relates to a vacuum cleaner nozzle (10; 10') adapted to contact a working surface, said vacuun cleaner nozzle including a brush nozzle (12; 12') having edge portions (16b, 16c; 16'b, 16'c) provided along the longitudinal sides of the brush nozzle (12; 12'). The invention also relates to a method to perform edge cleaning along the front edge portion, seen in the direction of motion, of the brush nozzle (12; 12'). Known vacuum cleaner nozzles have the disadvantage that when the brush nozzle is active dust and solid particles are transported around on the working surface that is vacuumed, i.e. dust and solid particles will not enter inside the brush rim. Further, known brush nozzles do not have edge cleaning along the front edge, seen in the direction of motion. Significant for the present invention is that the longitudinal edge portions (16b, 16c; 16'b, 16'c) are given a synchronized elevating/lowering movement whereby a front edge portion (16b; 16'b), seen in the direction of motion, is elevated from the working surface while simultaneously a rear edge portion (16c; 16'c), seen in the direction of motion, is lowered against the working surface.
(FR) La présente invention concerne une buse (10, 10') pour aspirateur conçue pour être en contact avec la surface de travail. Elle comporte une buse à brosse (12, 12') présentant des parties de bord (16b, 16c, 16'b, 16'c) le long des côtés longitudinaux de ladite buse à brosse (12, 12'). L'invention concerne aussi un procédé de nettoyage du bord le long du bord avant, vu dans le sens du déplacement, de la buse à brosse (12, 12'). Les buses d'aspirateurs connues ont l'inconvénient que, lorsque la buse à brosse est en action, de la poussière et des particules solides sont déplacées sur la surface de travail qui subit l'aspiration, c'est-à-dire qu'elles ne pénètrent pas à l'intérieur du bord de la brosse. En outre, les buses à brosse connues n'ont pas de nettoyage le long du bord avant, vu dans le sens du déplacement. Le point important de la présente invention est que les parties de bords longitudinales (16b, 16c, 16'b, 16'c) subissent un mouvement synchronisé montant et descendant de sorte qu'une partie du bord avant (16b, 16'b), vue dans le sens du déplacement, est levée au-dessus de la surface de travail, tandis que, en même temps, une partie du bord arrière (16c, 16'c), vue dans le sens du déplacement, est abaissée contre la surface de travail.
