この考案は、多重Ｖ型プリーツ構造のエアフイ
ルタの改良に関するものである。[Detailed Description of the Invention] This invention relates to an improvement of an air filter having a multiple V-type pleat structure.
この種のエアフイルタは、例えば第５図に示し

損失を招いていた。これは、いわゆる構造圧損は
処理風量の２乗に比例するので、風量が大きくな
るとホルダー３′，４′による構造圧損が急激に増
加するためと考えられる。 This type of air filter has a plurality of rectangular pleated panels 2 arranged in a zigzag pattern as shown in FIG.
The top surfaces of the upstream and downstream sides were fixed and sealed with flat plate-shaped holders 3' and 4', so when the processing air volume is large, these flat plate-shaped holders 3' and 4' cause air to flow out. Significant vortices were created in the flow, increasing ventilation resistance and causing pressure loss in the air filter. This is considered to be because the so-called structural pressure loss is proportional to the square of the processing air volume, so as the air volume increases, the structural pressure loss due to the holders 3' and 4' increases rapidly.
そこで、この考案は上記従来例におけるエアフ
イルタの圧力損失を抑制するためになされたもの
であり、その目的とするところは、材面積には
全く変化を与えることなく処理風量が大きい場合
の圧力損失を抑制することにある。 Therefore, this idea was made to suppress the pressure loss of the air filter in the conventional example described above, and its purpose is to reduce the pressure loss when the processing air volume is large without causing any change in the material area. It is about restraining.
以下、この考案の構成の一実施例として示した
図面に従つて説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings, which are shown as an embodiment of the structure of the invention.
第１図は、エアフイルタ本体１の一部切欠斜視

ている。 FIG. 1 shows a partially cutaway perspective view of the air filter main body 1, in which a plurality of rectangular pleated panels 2 are arranged in a zigzag pattern, and the top surfaces of the upstream and downstream sides of the pleated panels 2 adjacent to each other are shown in FIG. are fixed and sealed with holders 3 and 4 and installed in a frame 5.
上流側のホルダー３は、第３図に示した如く外
面を円弧形状３ａ、又は山形状、放物線形状等の
通風抵抗の小さい形状としている。 As shown in FIG. 3, the upstream holder 3 has an outer surface having a circular arc shape 3a, a mountain shape, a parabolic shape, or other shape with low ventilation resistance.
下流側のホルダー４は、第４図に示した如く内
面を山形状４ａ、又はその他通風抵抗の小さい形
状としている。 The holder 4 on the downstream side has an inner surface formed into a mountain shape 4a, as shown in FIG. 4, or other shape with low ventilation resistance.
この考案は上述した如く構成されているので、
その構造を標準サイズの6Vタイプ（プリーツパ

したもの）のエアフイルタに適用した場合、上流
側のホルダー３を第３図の如く外面を円弧状形状
３ａにすることにより定格風量（60H×610W×
292Dmmのフイルタの場合50m3／min）における圧
力損失は従来の25mmWGから約２mmWG低下し
た。そして、下流側のホルダー４を第４図の如く
内面を山形状４ａにすることにより圧力損失は更
に約３mmWG低下した。このエアフイルタの定格
風量を処理する際の風速は、計算によれば約
2.26m／secである。 This idea is structured as described above, so
When this structure is applied to a standard size 6V type air filter (12 pleated panels arranged in a zigzag pattern to form 6 sets of V shapes), the outer surface of the holder 3 on the upstream side is The rated air volume (60 H × 610 W ×
In the case of a 292 D mm filter, the pressure loss at 50 m 3 /min) was reduced by approximately 2 mmWG from the conventional 25 mmWG. The pressure loss was further reduced by about 3 mmWG by making the downstream side holder 4 have a mountain-shaped inner surface 4a as shown in FIG. According to calculations, the wind speed when processing the rated air volume of this air filter is approximately
It is 2.26m/sec.
さらに、この考案では第４図に鎖線で示した如
く、下流側のホルダー４の外面を円弧形状４ｂ、
又はその他の通風抵抗の小さい形状にすれば、圧
力損失が更に約１mmWG低下した。 Furthermore, in this invention, as shown by the chain line in FIG. 4, the outer surface of the holder 4 on the downstream side has an arc shape 4b,
Or, by using another shape with low ventilation resistance, the pressure loss was further reduced by approximately 1 mmWG.
したがつて、特にこの下流側のホルダー４にお
ける圧力損失の抑制効果は顕著なものである。 Therefore, the effect of suppressing pressure loss especially in the downstream holder 4 is remarkable.
従来の平板形状とした下流側のホルダー４′に
おいては、そのホルダー４′の内側に渦流が生ず
るばかりでなく、ホルダー４′外面にも若干の渦
流が生じたさめ、下流側のホルダー４′における
圧力損失が増大したのを、この考案ではホルダー
４の内面及び外面を通風抵抗の小さい形状とした
ため、上述の様な顕著な作用効果が生じたものと
考えられる。 In the conventional flat plate-shaped downstream holder 4', not only a vortex is generated inside the holder 4', but also a slight vortex is generated on the outer surface of the holder 4'. It is thought that the reason for the increased pressure loss is that in this invention, the inner and outer surfaces of the holder 4 are shaped to have a small ventilation resistance, resulting in the above-mentioned remarkable effect.
以上に示した如く、この考案のエアフイルタは
プリーツパネルの頂面を固定封泥するホルダーの
形状を通風抵抗の小さい形状に改良することのみ
により、材面積には全く影響を与えることなく
大風量を処理する際の圧力損失を抑制したもので
あり、実用的効果に優れている。 As shown above, the air filter of this invention can achieve a large air volume without affecting the material area at all, simply by improving the shape of the holder that fixes and seals the top surface of the pleated panel to a shape that has less ventilation resistance. It suppresses pressure loss during processing and has excellent practical effects.
