Title (EN) MULTISTAGE CYCLONE AND SURFACE CLEANING APPARATUS HAVING SAME
(FR) CYCLONE À ÉTAGES MULTIPLES ET APPAREIL DE NETTOYAGE DE SURFACE DOTÉ DU CYCLONE À ÉTAGES MULTIPLES
Abstract:
(EN) A hand vacuum cleaner has two nested cyclonic stages. Various designs for the dirt collection chamber of the second cyclonic stage and the design of multiple second stage cyclone inlets, which may use directing members, are provided. A length of the second stage cyclone chamber may be shorter than a length of the first stage cyclone chamber. A screen may be positioned laterally outwardly from the second stage cyclone to define a passage positioned between an inner side of the screen and the outer wall of the second stage cyclone wherein the screen may extend axially at least about 70% of a length of the second stage cyclone chamber. Different designs for emptying first and second stage dirt collect ion chambers are also provided.
(FR) L’invention concerne un aspirateur à main comprenant deux étages cycloniques emboîtés. Diverses conceptions concernent la chambre de collecte de saleté du second étage cyclonique et la conception de multiples entrées de cyclone de second étage, qui peuvent mettre en œuvre des éléments d'orientation. Une longueur de la chambre cyclonique de second étage peut être plus courte qu'une longueur de la chambre cyclonique de premier étage. Un écran peut être positionné latéralement vers l'extérieur à partir du cyclone de second étage pour définir un passage positionné entre un côté interne de l'écran et la paroi externe du cyclone de second étage, l'écran pouvant s'étendre axialement sur au moins environ 70 % d'une longueur de la chambre cyclonique de second étage. L'invention concerne également différentes conceptions permettant de vider les première et seconde chambres ioniques à collecte de saleté.
