Title
(EN) VACUUM CLEANER
(FR) ASPIRATEUR
(KO) 진공청소기
Abstract
(EN) A vacuum cleaner is disclosed. The vacuum cleaner comprises: a suction nozzle comprising a rotating cleaner positioned in the front of a suction port; and a cleaner body generating a suction force. A spiral first flow path is formed on the outer peripheral surface of the rotating cleaner. A fluffy covers the outer peripheral surface of the rotating cleaner except for the first flow path. The first flow path on the rotating cleaner is formed in a single line. If the suction nozzle comes into contact with a wall surface and is unable to move forward, the front space of the suction nozzle can communicate with the suction port via the first flow path, and thus foreign materials such as dust can be effectively sucked in from the edge of the wall surface.
(FR) Est divulgué un aspirateur. L'aspirateur comprend : une buse d'aspiration comprenant un dispositif de nettoyage rotatif positionné à l'avant d'un orifice d'aspiration ; et un corps d'aspirateur générant une force d'aspiration. Un premier trajet d'écoulement en spirale est formé sur la surface périphérique externe du dispositif de nettoyage rotatif. Un tissu pelucheux recouvre la surface périphérique externe du dispositif de nettoyage rotatif à l'exception du premier trajet d'écoulement. Le premier trajet d'écoulement sur le dispositif de nettoyage rotatif est formé en une seule ligne. Si la buse d'aspiration entre en contact avec une surface de paroi et ne peut pas se déplacer vers l'avant, l'espace avant de la buse d'aspiration peut communiquer avec l'orifice d'aspiration par l'intermédiaire du premier trajet d'écoulement et ainsi des matières étrangères telles que la poussière peuvent être efficacement aspirées à partir du bord de la surface de paroi.
(KO) 진공청소기가 개시된다. 진공청소기는, 흡입구 앞에 위치하는 회전클리너를 포함하는 흡입노즐 및 흡입력을 발생시키는 청소기본체를 포한한다. 회전클리너의 외주면에는 나선형의 제1 유로가 형성되고, 회전클리너의 외주면은 제1 유로를 제외하고 플러피에 의해 덮혀지며, 회전클리너에서 제1 유로는 하나의 라인으로 이루어진다. 흡입노즐이 벽면에 닿아 앞쪽으로 이동하지 못하는 경우, 흡입노즐의 앞쪽 공간은 제1 유로를 통하여 흡입구와 연통될 수 있으며, 이에 따라 벽면 모서리에서 먼지와 같은 이물질을 효과적으로 흡입할 수 있다.
