Title
(EN) FILTER UNIT AND AIR PURIFIER HAVING SAME
(FR) ENSEMBLE FILTRE ET PURIFICATEUR D'AIR DOTÉ DUDIT ENSEMBLE
(KO) 필터유닛, 및 이를 구비한 공기 청정기
Abstract
(EN) A filter unit comprises: a frame which forms the exterior thereof in a form of encompassing an opening enabling air to flow therethrough, and which has a collecting surface and another surface that is formed on the side opposite to the collecting surface; and a filter member which is formed in the opening and which filters out foreign substances included in the flowing air, wherein folding grooves are formed on the other surface of the frame, and the folding grooves can be respectively formed at at least two points of the frame so that, when external force is applied toward the collecting surface from the other surface of the frame, a portion of the frame divided with respect to the folding groove rotates relative to another portion thereof so that a portion of the collecting surface approaches the other portion thereof, and thus the frame can be folded.
(FR) Un ensemble filtre comprend : un cadre destiné à former l'extérieur de l'ensemble de manière à englober une ouverture permettant l'écoulement d'air à travers cette dernière, et comportant une surface de collecte et une autre surface formée sur le côté opposé à la surface de collecte ; et un élément filtre formé dans l'ouverture et destiné à filtrer des substances étrangères comprises dans l'air circulant. Des rainures de pliage sont formées sur l'autre surface du cadre, et les rainures de pliage peuvent être formées respectivement au niveau d'au moins deux points du cadre de façon que, lorsqu'une force externe est appliquée vers la surface de collecte à partir de l'autre surface du cadre, une partie du cadre, divisée par rapport à la rainure de pliage, tourne par rapport à une autre partie du cadre, de sorte qu'une partie de la surface de collecte se rapproche de l'autre partie de la surface, et qu'ainsi le cadre puisse être plié.
(KO) 필터유닛은 공기가 유동할 수 있는 개구부를 둘러싸는 형태로 외형을 형성하고, 포집면 및 상기 포집면의 반대측에 형성되는 타면을 구비하는 프레임; 및 상기 개구부에 형성되며, 유동하는 공기에 포함된 이물질을 여과하는 필터부재; 를 포함하되, 상기 프레임의 상기 타면에는 접이홈이 형성되고, 상기 접이홈은 상기 프레임의 타면에서 상기 포집면을 향해 외력을 가했을 때, 상기 접이홈을 기준으로 구분되는 상기 프레임의 일부가 다른 일부에 대해 상대 회전하여, 상기 포집면의 일부가 다른 일부를 향해 접근하여 상기 프레임이 접히도록 상기 프레임의 적어도 두 지점에 각각 형성될 수 있다.
