Description
【０００１】[0001]
この考案は、例えば自動車のエアクリ−ナなどに用いられるフィルタエレメン トに関し、特に、濾過部材が菊花状に成形されるフィルタエレメントの折形状に 関する。 The present invention relates to a filter element used in, for example, an automobile air cleaner, and more particularly to a folded shape of a filter element in which a filter member is formed into a chrysanthemum shape.
【０００２】[0002]
従来から、自動車用エンジンの吸気系等に用いられるエアクリ−ナ用フィルタ エレメントは円筒形のフィルタエレメントが多く用いられていた。このような円 筒形フィルタエレメントは、一般に濾過部材に多数の山折線および谷折線を交互 に反復形成するとともに、幅方向の一方の縁部を外周として濾過部材を展開した エレメント本体に、内筒および上下エントプレ−トを組み付けた構造となってい る。 Conventionally, a cylindrical filter element has often been used as an air cleaner filter element used in an intake system of an automobile engine. In such a cylindrical filter element, generally, a large number of mountain fold lines and valley fold lines are alternately and repeatedly formed on the filter member, and the filter member is expanded with one edge in the width direction as the outer circumference, and the inner cylinder is It also has a structure in which the upper and lower entrants are assembled.
【０００３】 最近、特に乗用車ではエンジンル−ムを低くするため、ハウジングおよびカバ −の間にフィルタエレメントを挟み込んで固定する構造のエアクリ−ナの矩形フ ィルタエレメントや扇形フィルタエレメントが開発されており、その形状や濾過 面積の点でエンジンル−ムの狭い空間の中で使用され、他の部品との取り合い上 有利となっている。Recently, particularly in passenger cars, in order to lower the engine room, a rectangular filter element and a fan-shaped filter element of an air cleaner having a structure in which a filter element is sandwiched and fixed between a housing and a cover have been developed. In terms of its shape and filtration area, it is used in the narrow space of the engine room, which is advantageous in terms of compatibility with other parts.
【０００４】 しかしながら、扇形構造のフィルタエレメントはフィルタエレメントを長持ち させるために濾過面積を増やそうとしてフィルタエレメントの折り回数を増やす と中心部の濾過部材が密集し過ぎて不具合が生じていた。However, in the fan-shaped filter element, when the number of folding of the filter element is increased in order to increase the filtration area in order to prolong the life of the filter element, the filter member in the central portion becomes too dense, causing a problem.
【０００５】[0005]
即ち、フィルタエレメントのフィルタ寿命を長くするためには、フィルタエレ メントの濾過面積をできるだけ多く取り、なおかつ濾過面積全体を有効に機能さ せさなければならない、そのために扇形フィルタエレメントの外周側の折り山と 折り山のピッチの広い部分を利用して外周部の濾過面積を増大させ中心部の密集 が生じないようにする必要がある。 That is, in order to prolong the filter life of the filter element, the filtration area of the filter element must be as large as possible and the entire filtration area must function effectively. It is necessary to increase the filtration area of the outer peripheral part by using the part where the pitch of the crest and the fold crest is wide so that the central part does not become dense.
【０００６】 この考案は以上の問題を解決するものであって、フィルタエレメントの外側と 中心部の折り形状を変えて濾過面積を増大するとともに、フィルタエレメントの 濾過部材全面を有効に働かせることを目的とする。This invention solves the above problems, and aims to increase the filtering area by changing the folding shapes of the outer side and the central part of the filter element and to effectively operate the entire filtering member of the filter element. And

前記目的を達成するため、この考案は、長方形状の濾過材を折線に沿って折曲 げ、前記濾過材の両端部を長手方向に沿った中心線を中心として扇状に拡げ、該 濾過材の一方の端部同士或いは他方の端部同士を気密状に接着して菊花状のフィ ルタエレメントを形成するための折形状であって、前記濾過材には、該濾過材の 端縁部に対して傾斜する第１の傾斜山折線をほぼ一定のピッチを有して反復形成 するとともに、この第１の傾斜山折線と前記濾過材の幅方向の中心線との交点を 中心として該第１の傾斜山折線を１８０度回転させた角度を有する第２の傾斜山 折線を前記第１の傾斜山折線間にほぼ一定のピッチを有して形成し、この第１の 傾斜山折線と第２の傾斜山折線との間には該第１および第２の傾斜山折線間のピ ッチが小さい側の前記濾過材の幅方向の一方の縁部から前記濾過材の中心線に至 り、かつ該濾過材の端縁部と平行な平行谷折線を形成するとともに、この平行谷 折線の延長線上に平行山折線を形成し、この平行谷折線および平行山折線と前記 濾過材の中心線との交点から該中心線より平行山折線が形成された側の濾過材縁 部に至る傾斜谷折線を形成し、前記濾過材の幅方向の縁部における山折線と谷折 線との折ピッチをほぼ一定に設定してなることを特徴する。 In order to achieve the above-mentioned object, this invention folds a rectangular filter medium along a fold line and expands both ends of the filter medium in a fan shape around a center line along the longitudinal direction. It has a folded shape for forming a chrysanthemum-shaped filter element by air-tightly adhering one end portion or the other end portion to each other. The first sloped mountain fold line that is inclined with respect to each other is repeatedly formed with a substantially constant pitch, and the first sloped mountain fold line and the center line of the filter medium in the width direction are centered at the first slope mountain fold line. A second inclined mountain fold line having an angle obtained by rotating the inclined mountain fold line by 180 degrees is formed with a substantially constant pitch between the first inclined mountain fold lines, and the first inclined mountain fold line and the second inclined mountain fold line are formed. The side where the pitch between the first and second inclined mountain fold lines is small between the inclined mountain fold line A parallel valley fold line extending from one edge in the width direction of the filter medium to the center line of the filter medium and parallel to the end edge of the filter medium is formed, and parallel to the extension line of the parallel valley line. A mountain fold line is formed and an inclined valley fold line extending from the intersection of the parallel valley fold line and the parallel mountain fold line to the center line of the filter medium to the edge of the filter medium on the side where the parallel mountain fold line is formed from the center line is formed. The folding pitch between the mountain fold line and the valley fold line at the widthwise edge of the filter medium is set to be substantially constant.

濾過材を菊花状に展開したときに、最終形状であるフィルタエレメントの外周 側の折ピッチと中心部側の折ピッチを変えることにより全体として濾過面積を増 大させることができるとともに、中心部に濾過材の密集が生じないようにしたの で濾過材全体を有効に活用して長持ちさせることができる。 When the filter medium is expanded into a chrysanthemum shape, the filtration area can be increased as a whole by changing the folding pitch on the outer peripheral side and the folding pitch on the central side of the filter element, which is the final shape. Since the filter media is prevented from being congested, it is possible to effectively utilize the entire filter media and prolong its life.
