Title
(EN) DUST COLLECTING APPARATUS AND CLEANER HAVING SAME
(KO) 집진장치 및 이를 구비하는 청소기
Abstract
(EN)
A dust collecting apparatus of the present invention comprises: a housing in a cylindrical shape forming an outer shape of the dust collecting apparatus; a cyclone formed in the housing, and generating a swirl so as to separate dust from air introduced into the housing; axial flow swirl tubes receiving the air and fine dust which passed through the cyclone, and generating a swirl so as to separate the fine dust from the air; and a mesh surrounding the outside of the axial flow swirl tubes so as to form a boundary between the cyclone and the axial flow swirl tubes. The axial flow swirl tubes are accumulated in multi-stages. Furthermore, the axial flow swirl tubes of each stage are arranged in two rows such that a first row and a second row may face the opposite direction from each other. Moreover, a length in an axial direction of each axial flow swirl tube is gradually elongated while approaching the axial flow swirl tube arranged at the center of each stage. COPYRIGHT KIPO 2019

본 발명의 집진장치는, 집진장치의 외관을 형성하는 원통 형상의 하우징; 상기 하우징의 내측에 형성되고, 상기 하우징의 내측으로 유입된 공기로부터 먼지를 분리하도록 선회류를 일으키는 사이클론; 상기 사이클론을 통과한 공기와 미세먼지를 공급받으며, 공기로부터 미세먼지를 분리하도록 선회류를 일으키는 축류식 스월 튜브들; 및 상기 사이클론과 상기 축류식 스월 튜브들의 경계를 형성하도록 상기 축류식 스월 튜브들의 외측을 감싸는 메쉬를 포함하고, 상기 축류식 스월 튜브들은 다단으로 적층되고, 각 단의 축류식 스월 튜브들은 2열로 배열되어 제1 열과 제2 열이 서로 반대 방향을 향하도록 배치되며, 각 축류식 스월 튜브의 축 방향 길이는 각 단의 중심에 배치된 축류식 스월 튜브에 가까워질수록 점차 길어진다.
