(EN) DUST COLLECTING APPARATUS AND CLEANER HAVING SAME
(FR) APPAREIL DE COLLECTE DE POUSSIÈRE ET NETTOYEUR LE COMPRENANT
Abstract
(EN)
A dust collector according to the present disclosure may include a cylindrical housing configured to form an outer appearance of the dust collector; a cyclone formed inside the housing to cause a swirling flow to separate dust from air introduced into the housing; axial inlet type swirl tubes configured to receive air and fine dust that have passed through the cyclone, and cause a swirling flow to separate the fine dust from the air; and a mesh configured to surround an outside of the axial inlet type swirl tubes to form a boundary between the cyclone and the axial inlet type swirl tubes, wherein the axial inlet type swirl tubes are stacked in multiple stages and the axial inlet type swirl tubes in each stage are arranged in two columns such that the first and second columns are disposed toward opposite directions to each other, and an axial length of each of the axial inlet type swirl tubes gradually increases as it approaches the axial inlet type swirl tube disposed at the center of each stage.

(FR)
Un appareil de collecte de poussière, selon la présente invention, comprend : un boîtier cylindrique qui forme l'extérieur de l'appareil de collecte de poussière ; un cyclone qui est formé à l'intérieur du boîtier et génère un écoulement tourbillonnant de façon à séparer la poussière de l'air introduit à l'intérieur du boîtier ; des tubes de tourbillonnement axiaux qui reçoivent de l'air et de la poussière fine qui ont traversé le cyclone et génèrent un écoulement tourbillonnant de façon à séparer la poussière fine de l'air ; et une maille qui recouvre les côtés extérieurs des tubes de tourbillonnement axiaux de façon à former une limite entre le cyclone et les tubes de tourbillonnement axiaux, les tubes de tourbillonnement axiaux étant empilés en de multiples couches, et les tubes de tourbillonnement axiaux dans chaque couche étant agencés en deux colonnes de telle sorte que la première colonne et la seconde colonne sont disposées de façon à faire face à des directions différentes l'une de l'autre, et la longueur axiale-directionnelle de chacun des tubes de tourbillonnement axiaux augmentant progressivement vers le tube de tourbillonnement axial disposé au centre de chaque couche.
