Description
【考案の詳細な説明】 （産業上の利用分野） この考案は濾過エレメント、特にエアクリーナ用エレメ
ントに関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a filter element, particularly an element for an air cleaner.
（従来の技術） 内燃機関のエアクリーナなどには角形の枠体内にシート
状濾材をひだ折りした濾過体を配設したものが用いられ
ており、例えば実開昭57-73363号公報に開示されてい
る。第３図に示す濾過エレメント10のように、角形の枠
体11内にひだ折り濾紙でなる濾過体12を配設し、枠体11
の下端縁にシールパッキン13を設けたものである。濾過
体12はひだ折り方向が一定した単一のものである。(Prior Art) As an air cleaner for an internal combustion engine, one having a filter body in which a sheet-shaped filter medium is folded inside a square frame is used. For example, it is disclosed in Japanese Utility Model Publication No. 57-73363. There is. Like a filter element 10 shown in FIG. 3, a filter body 12 made of a fold-fold filter paper is arranged in a rectangular frame body 11 to form a frame body 11.
A seal packing 13 is provided on the lower edge of the. The filter body 12 is a single filter body having a constant fold direction.

通過する。The filter element 10 is housed in a casing 16 (FIG. 4) of an air cleaner having an inlet pipe 14 and an outlet hole 15, and the casing 16 is divided into a dust packing side and a clean side for use. In order to flatten the casing 16, the inlet pipe 14 is installed sideways, and air flows in the direction of arrow D (the direction of arrow B or C in FIG. 3), spreads on the upper surface 12a of the filter body 12 and to the lower surface as a whole ( Figure 3 arrow A)
pass.
（考案が解決しようとする課題） この場合、矢印Ｂ方向に流体が流入すると、流体はまづ
各ひだの正面側山腹上部に衝突して濾材を通過し矢印Ａ
方向に急激に方向を変えるから、流れが乱れて圧力損失
が大となる。しかし各ひだ山の正面下部すなわち谷部
と、各ひだ山の背面とは流体の通過量が比較的少なく、
この部分の目詰まりの進行は遅い。(Problems to be solved by the invention) In this case, when the fluid flows in the direction of the arrow B, the fluid collides with the upper part of the front side hillside of each fold and passes through the filter medium to the arrow A.
Since the direction changes rapidly, the flow is disturbed and the pressure loss becomes large. However, the amount of fluid passing through the lower part of the front of each fold mountain, that is, the valley, and the back of each fold mountain is relatively small,
The progress of clogging in this part is slow.
一方、矢印Ｃ方向に流体が流入する場合は、各ひだ山の
稜線に平行でひだ山の正面、背面の区別がなく谷方向へ
流入するから流れの乱れが少ないが、濾材全面にわたり
目詰まりが進行する。特に谷部においては流量が多い傾
向となり、この部分では向かい合った濾材の間にダスト
が堆積し、抵抗を高めるとともに通路面積を狭めてしま
う。On the other hand, when the fluid flows in the direction of arrow C, it is parallel to the ridgeline of each fold mountain and flows in the valley direction without distinction between the front and back sides of the fold mountain, so there is little turbulence in the flow, but clogging of the entire filter medium occurs. proceed. Especially in the valley portion, the flow rate tends to be large, and in this portion, dust is accumulated between the filter media facing each other, which increases the resistance and narrows the passage area.
上記の状態であるから矢印Ｂ方向に流入をさせるときは
初期圧力損失（通気抵抗）が高いが目詰まり寿命（捕捉
ダストによる抵抗増加が所定値に達するまでの期間）は
比較的長い。また矢印Ｃ方向に流入をさせるときは初期
圧力損失は少ないが目詰まり寿命は比較的短い。In the above state, when the flow is made to flow in the direction of arrow B, the initial pressure loss (ventilation resistance) is high, but the clogging life (the period until the increase in resistance due to trapped dust reaches a predetermined value) is relatively long. Further, when the flow is made to flow in the direction of arrow C, the initial pressure loss is small, but clogging causes a relatively short life.
従来の濾過エレメントは流体の流入方向に対しひだ折り
の向きが直交するか平行であるかにより、上記２種の特
性のいずれかしか選択することができず、これを調整し
ようとすれば濾材の材質や、濾過面積の変更などの手段
が必要であった。In the conventional filter element, only one of the above two characteristics can be selected depending on whether the direction of the folds is orthogonal or parallel to the inflow direction of the fluid. Means such as changing the material and filtration area were necessary.
（課題を解決するための手段） 角形をなす枠体内に、枠体の一辺に平行な複数の区画板
を設けて枠体内部を区画し、各区画内にひだ折りしたシ
ート状濾材でなる濾過体を、各のひだが直交するように
配置し、各濾過体の端部を区画板および枠体内壁に接着
シールするものである。(Means for Solving the Problem) In a rectangular frame body, a plurality of partition plates parallel to one side of the frame body are provided to partition the inside of the frame body, and a filter formed by a sheet-shaped filter medium folded in each partition. The body is arranged so that the folds are orthogonal to each other, and the ends of the filter bodies are adhesively sealed to the partition plate and the inner wall of the frame.
（作用） この濾過エレメントに角形の枠体の一辺に沿った方向に
流体を流入させると、各濾過体は流体の流入方向に対し
ひだ折りの方向が直交するものと平行なものとでそれぞ
れの特性を有するから、従来の直交、または平行な単一
の濾過体の特性の中間的な特性を有するもの、すなわち
前記矢印Ｂ方向に対するものより初期圧力損失が低く、
矢印Ｃ方向に対するものよりも寿命の長い濾過エレメン
トが得られる。(Operation) When a fluid is made to flow into this filtering element in a direction along one side of a rectangular frame, each of the filtering elements has a fold-fold direction orthogonal to the fluid inflow direction and a parallel one. Since it has the characteristics, the initial pressure loss is lower than that of the characteristics of the conventional orthogonal or parallel single filter body, that is, the one in the direction of the arrow B,
A filter element with a longer life than that for the direction of arrow C is obtained.
この場合濾過エレメントの特性は各濾過体への濾過面積
の配分によって決まるが、特に流入する流れの中央部に
配設した濾過体が、流れの両側部に配設した濾過体より
も大きく影響する。In this case, the characteristics of the filter element are determined by the distribution of the filter area to each filter body, but in particular, the filter body disposed in the center of the inflowing flow has a greater effect than the filter bodies disposed on both sides of the flow. .

命が長い。(Example) An example is shown in FIG. 1 and FIG. A filter element 1 of an air cleaner has a filter body 3, 4 and 5 made of fold-fold filter paper, which is disposed inside a rectangular frame body 2 made of a metal plate or paper.
Seal packings 6 made of urethane foam are attached to the four edges around the lower end of the frame body 2. Inside the frame body 2, paper partition plates 7 and 8 parallel to one side of the frame body are provided so that the inside of the frame body 2 is
The filter body 4 is provided between the partition plates 7 and 8. A filter body 3 or 5 is provided between the partition plate 7 or 8 and one side of the frame body 2, and each peripheral end of each filter body is adhesively sealed to the partition plate 7 or 8 and the inner wall of the frame. . The fold ridges of the filter bodies 3 and 5 are in the same direction, and the fold ridge direction of the filter body 4 is orthogonal to the fold pile direction of the filter bodies 3 and 5. With this combination, the initial resistance is lower than that of the pleats that are orthogonal to the direction of inflow of air, and the life is longer than that of only the pleats that are parallel.

要がなく製作容易である。When the partition plates 7 and 8 are provided like the filter element 1, for example, the left and right and the central portion of the inflow air of the arrow B (FIG. 3) and the inflow air of the arrow C (FIG. 3) are provided. It can be divided into the front and rear and the central portion to have optimum air receiving shapes. Further, the positions of the partition plates 7 and 8 can be easily adjusted to adjust the area of each partition, and three or more partition plates are set to subdivide the partition to adapt to the air flow for each site. It is also easy to do.
In this case, since the shape of each partition partitioned by the partition plate is all quadrangular, the pleated filter medium does not need to have a special shape and can be easily manufactured.

なり、製作および組付け容易である。(Effect of the Invention) Since the filter element of the present invention is provided with a plurality of filter bodies whose folds are orthogonal to each other, the filter medium material and the filter area can be reduced with respect to the fluid flowing in from the lateral direction parallel to the upper surface of the filter body. The characteristics of the filter element can be adjusted without changing, and a filter element having a reduced initial resistance and a long life within a certain range can be obtained. Therefore, the characteristics of the flat air cleaner containing the rectangular element can be adjusted by the filtering element of the present invention. Furthermore, the position and number of partition plates, or the orientation can be arbitrarily selected, so an optimal filter arrangement is selected according to the inflow state of fluid such as air flow to reduce the pressure loss of the filter element and extend the service life. You can measure. In addition, this partition plate and each filter body are all quadrangular, which facilitates production and assembly.
