Title (EN) VACUUM CLEANER POWER NOZZLE HAVING SELECTIVELY INTRODUCED SECONDARY AIRFLOW FOR OPERATION ON CARPETED SURFACES
(FR) BUSE D'ASPIRATEUR MOTORISÉE À FLUX D'AIR SECONDAIRE INTRODUIT DE MANIÈRE SÉLECTIVE POUR UNE UTILISATION SUR DES SURFACES RECOUVERTES DE MOQUETTE
Abstract:
(EN) A vacuum cleaner power nozzle assembly, comprising: an intake opening formed on a lower side of said vacuum nozzle assembly; a powered lower brush mounted in said intake opening so as to extend generally transverse to a front-to-back direction of movement of said power nozzle assembly; and at least one selectively openable passage that permits entry of a secondary flow of air into said intake opening on a front side of said roller brush, so that said secondary flow of air reduces down force exerted by a vacuum in said intake opening, and so that said secondary flow of air is drawn downwardly and under said roller brush by rotation of said roller brush so as to aid in dislodging and removing particulate matter from a carpet.
(FR) L'invention concerne un ensemble buse motorisé d'aspirateur, comprenant : une ouverture d'entrée formée sur un côté inférieur dudit ensemble buse à vide; une brosse inférieure motorisée montée dans ladite ouverture d'entrée de façon à s'étendre généralement transversalement à une mouvement de l'avant vers l'arrière dudit ensemble de buse motorisé; et au moins un passage pouvant être ouvert de manière sélective qui permet l'entrée d'un flux d'air secondaire dans ladite ouverture d'entrée sur un côté avant de ladite brosse à rouleau, de telle sorte que ledit flux d'air secondaire réduit la force descendante exercée par un vide dans ladite ouverture d'entrée, et de sorte que ledit flux d'air secondaire soit aspiré vers le bas et sous ladite brosse à rouleau par rotation de ladite brosse à rouleau de façon à favoriser l'extraction et l'élimination de la matière particulaire contenue dans une moquette.
