- the pressure loss measuring machine connects a measurement port (duct) and a ventilation register to be measured so that there is no air leakage.
- the diameter of the duct which is the measurement port connected to the ventilation register, is the same as the size of the ventilation port to which the ventilation register is actually mounted.
- the diameter of the duct serving as a measurement port is ⁇ 100 mm (100 pie).
- An appropriate orifice is selected according to the air volume.
- the rectifying network and the wind expansion plate are installed in order to make the wind speed in the air tank uniform.

- the conventional electrostatic filter was set for two different types of housing designs and the pressure loss was measured (A and B in FIG. 22). Although it is the same electrostatic filter, it can be seen that the pressure loss of B is smaller than that of A due to the difference in housing design (ie, B is more than A when, for example, the same static pressure of 100 Pa is applied). Large amount of permeated gas).

- FIG. 23A shows a time-series change in pressure loss, and FIG. 23B shows a comparison of collection efficiency.
- the pressure loss is a digital manometer (manometer (F-213) manufactured by Tsukubarika Seiki Co., Ltd.), which is the differential pressure upstream and downstream of the filter when air is passed through the filter unit, which is the measurement object, at an air volume of 2.5 m / sec. ).
- the dust collection efficiency of 0.3 to 0.5 ⁇ m exceeds 70%, and a gentle curve is drawn even with the passage of time of pressure loss. It has been found that it can withstand use.

- the initial value (B1) of the microfilter is considered to have leaked from between the housing and the filter. And it is thought that the particle
- the microfilter is considered to have a short life because clogging due to particles adhering to the microfiber fiber with time progresses faster than other filters.
- pressure loss was measured with a nanofilter having a pitch of about 4 mm and a peak height of about 15 mm and a nanofilter having a pitch of about 4 mm and a peak height of about 25 mm.
- Results are shown in FIG. A represents a ventilation register having a pitch of about 4 mm, a mountain height of about 15 mm, and a back space of about 5 mm
- B represents a ventilation register having a pitch of about 4 mm, a mountain height of about 25 mm, and a back space of about 5 mm.
- Example 4 durability
- a nanofilter having a fiber diameter of about 60 nm and a pore diameter of about 5 ⁇ m was actually attached to the inventor's home and used for one month to measure pressure loss. As a result, it was found that the air flow rate was reduced by about 6% due to clogging.

室内の換気には、主に3つの種別のシステムが存在する。1つ目は給排気ともに機械(電動ファン)で強制的に行う第1種換気システムである。2つ目は、排気側は自然換気、給気側は機械換気で強制的に行う第2種換気システムである。これは、クリーンルームなどで用いられることが多く、住宅にはほとんど用いられない。3つ目は、機械換気により強制的に排気し、その分を自然給気口(室内換気レジスタ)で給気する第3種換気システムである。 (Detailed explanation)
There are three main types of indoor ventilation. The first type is a first type ventilation system in which supply and exhaust are forcibly performed by a machine (electric fan). The second type is a second type ventilation system forcibly performing natural ventilation on the exhaust side and mechanical ventilation on the supply side. This is often used in a clean room or the like, and is rarely used in a house. The third type is a
本発明の換気レジスタ1は建物の内壁5に設けられる換気口2の屋内側に取り付けられ、屋外の粉じんや雨粒等の異物の屋内への侵入を抑制するために使用される。こうした屋内用レジスタ1は、図1~図5で示すように差込筒3と、フェイス部4とを備える。 (First embodiment [FIGS. 1 to 6])
The
差込筒3は、図1で示すように略円筒状でなる。換気口2に入り込んだ空気11aは、こうした差込筒3の内部を通過することができる。また、差込筒3は建物の内壁5に開口する換気口2に差し込んで取り付けることができる。差込筒3の屋内側開口端3aからは外方に向かう外向きフランジ6が設けられており、この外向きフランジ6にはネジ止め部Sが設けられている。また、外向きフランジ6はその外形に沿う外枠部6aを有する。差込筒3の材質は任意の材質を取り得る。例えば、アルミニウムやステンレスなどの金属であってもよいし、樹脂などのプラスチック材であってもよい。好ましい実施形態において、差込筒3は、軽量化が図れる樹脂材で設けられるが、本発明はこれに限定されない。差込筒の形状は筒体であれば、任意の形態を取り得る。例えば、三角筒体であってもよいし、四角筒体であってもよいし、多角筒体であってもよいし、円筒体であってもよい。 (Insert tube)
The plug-in
フェイス部4は、図1~図5で示すように平板部7と、整流ドーム部7bと、平板部7の裏面(差込筒3と対向する面)に設けられる筒型プリーツフィルター8と、差込筒3に対する保持部9とを備える。なお、本実施形態では筒型フィルターとしてプリーツフィルターを用いた場合を例示したが、プリーツ加工は必ずしも必要ではなく、プリーツ加工されていない筒型フィルターを用いる場合も本発明の範囲内であることは当然に理解されるべきである。フェイス部4の材質は任意の材質を取り得る。例えば、アルミニウムやステンレスなどの金属であってもよいし、樹脂などのプラスチック材であってもよい。好ましい実施形態において、フェイス部4は、軽量化が図れる樹脂材で設けられるが、本発明はこれに限定されない。 [Face part]
As shown in FIGS. 1 to 5, the
換気レジスタ1を図4,図5で示すように、建造物の内壁5に設けられた換気口2に取り付ける。具体的には、換気口2の内径を差込筒3の外径と同程度になるように設け、差込筒3を換気口2に挿入する。差込筒3の外周面には、換気口2の内周面との間の間隙を埋めるパッキン(図示略)が配置されている。その後、外向きフランジ6のネジ留め部Sをネジ留めすることで、換気レジスタ1を内壁5に対して固定することができる。 [Explanation of usage]

第1実施形態の換気レジスタ1は、上記のように複数のプリーツ部8aを有する筒型プリーツフィルター8を備えるため、平板状のプリーツフィルターを備える場合と比較して限られた空間内で表面積を大きくすることができる。よって、圧力損失の増加を抑制することができる。 [Method of suppressing increase in pressure loss]

前記第1実施形態では、フェイス部4や外向きフランジ6が略正方形でなる例を示した。しかし、第1実施形態の筒型プリーツフィルター8は差込筒3と略同径の断面略円形の筒状であり、差込筒3に挿入されるため、フェイス部4や外向きフランジ6の形状に影響をあまり与えない。そのため、外向きフランジ6にネジ留め部Sを設けることさえできれば、例えばフェイス部4や外向きフランジ6が略円形である換気レジスタ14としたり(図7(a)参照)、略三角形である換気レジスタ15とするなど(図7(b)参照)、フェイス部4や外向きフランジ6の形状を自由に設計することができる。よって、より高い美観を奏する換気レジスタ1とすることができる。 Modification [FIG. 7]:

As shown in FIGS. 15 to 17, the opening /
第1の翼体53は略半円形の板状でなり、差込筒52に対して回動可能に軸支されている。具体的には、第1の翼体53は差込筒52の内側上面に対して固定される固定部53aと、内側下面に対して固定される固定部53bとを有しており、第1の翼体53は、固定部53aと固定部53bとを結んだ回動軸A1を中心として回動する。こうした回動軸A1は、左右方向Xにおける第1の翼体53の中央よりも差込筒52の中心側に配置されている。第2実施形態において、第1の翼体53の形状が略半円形である場合について説明しているが、本発明はこれに限定されない。第1の翼体53の形状は、差込筒52の外縁に沿う形状であれば任意の形態であり得る。例えば、差込筒52が三角筒体であれば第1の翼体53は三角形であってもよいし、差込筒52が四角筒体であれば第1の翼体53は四角形であってもよいし、差込筒52が多角筒体であれば第1の翼体53は半多角形であってもよい。 [First wing]
The
第2の翼体54は第1の翼体53と同様に略半円形の板状でなり、第2の翼体54の端面54cと第1の翼体53の端面53fとが端面同士を対向させた状態で差込筒52の室内側開口部52aを覆って通気路Rを塞ぐ略円状の平板部を形成する。第2実施形態において、第2の翼体54の形状が略半円形である場合について説明しているが、本発明はこれに限定されない。第2の翼体54の形状は、第1の翼体53と同様に、差込筒52の外縁に沿う形状であれば任意の形態であり得る。例えば、差込筒52が三角筒体であれば第2の翼体54は三角形であってもよいし、差込筒52が四角筒体であれば第2の翼体54は四角形であってもよいし、差込筒52が多角筒体であれば第2の翼体54は半多角形であってもよい。 [Second wing]
Similar to the
連結片部55は棒片状でなり、第1の翼体53と第2の翼体54とを連結する。連結片部55は一端側に設けられて第1の翼体53における外周側部53Aであって室外側の板面に軸支される第1の軸支部55aと、他端側に設けられて第2の翼体54における中心側部54Bであって室外側の板面に軸支される第2の軸支部55bとを有する。 [Connected piece]

押圧片部56は、図9~図11に示すように、棒を折り曲げて形成されており、第1の取付軸部56bと、第2の取付軸部56cと、突出部56Aとを有する。押圧片部56を形成する棒の材質は任意の材質であり得る。例えば、硬化プラスチック樹脂などであってもよいし、木材であってもよいし、ステンレスやアルミニウムなどの金属であってもよい。 (Pressing part)
As shown in FIGS. 9 to 11, the
まず、図18を参照しつつ通気路Rを開く作業について説明する。第1の翼体53と第2の翼体54とが通気路Rを閉じた閉状態にある換気レジスタ51について、操作部56c2を開方向に回動操作する(矢示P1)。こうすることで押圧片部56が開方向に回動して、押圧部56aが閉状態にある第1の翼体53の翼片53cを室外側に向けて押圧する(矢示P2)。第1の翼体53が回動軸A1を中心軸として回動すると、第1の翼体53の外周側部53Aが差込筒52の内部に入り込み、中心側部53Bが室内側に入り込む。しかし、中心側部53Bの左右方向Xにおける長さは外周側部53Aの左右方向Xにおける長さよりも短く形成されているため、室内側への突出量は短くなっている。こうして第1の翼体53が開状態となる。 [Explanation of operation method when opening the ventilation register from the closed state to the open state]
First, the operation of opening the air passage R will be described with reference to FIG. For the
続いて図19を参照しつつ通気路Rを閉じる作業について説明する。第1の翼体53と第2の翼体54とが通気路Rを開いた開状態にある換気レジスタ51について、操作部56c2を閉方向に回動操作する(矢示C1)。こうすることで押圧片部56が閉方向に回動して、押圧部56aが開状態にある第1の翼体53の保持部53dを閉方向に向けて引っ張るように押圧する。これにより第1の翼体53が回動軸A1を中心軸として回動すると、第1の翼体53の外周側部53Aが室内側に移動し(矢示C2)、中心側部53Bは差込筒52側に移動する。こうして第1の翼体53が閉状態となる。 [Explanation of operation method when changing the ventilation register from the open state to the closed state]
Next, the operation of closing the air passage R will be described with reference to FIG. For the
前記第2実施形態では、第1の取付軸部56bと第2の取付軸部56cとが略同じ長さでなり、押圧部56aが高さ方向Zにおける略中央に設けられる例を示した。これに対して、取付軸部56b,56cの何れか一方が他方よりも長く設けられ、押圧部56aが上側か下側のどちらかに偏って設けられることとしても良い。 Variation:

The present invention has been described with reference to the preferred embodiments for easy understanding. Hereinafter, the present invention will be described based on examples. However, the above description and the following examples are provided only for the purpose of illustration and are not intended to limit the present invention. Accordingly, the scope of the present invention is not limited to the embodiments or examples specifically described in the present specification, but is limited only by the scope of the claims.
一般的に使用されている換気レジスタとして従来の静電フィルターを備えた給気レジスタと、本発明の2種類のナノファイバーフィルターをそれぞれ備えた給気レジスタとを圧力損失測定機にセットし圧力損失を測定した。圧力損失の測定は、JIS C9603(換気扇)の付属書1に記載された測定方法に基づいて行う。圧力損失測定機は、図25に示すように、空気漏れがないように、測定口(ダクト)と測定する換気レジスタとを接続する。換気レジスタと接続される測定口であるダクトの径は、実際に換気レジスタが装着される換気口の大きさと同じとする。今回の測定において、測定口であるダクト径は、φ100mm(100パイ)である。オリフィスは、風量に応じて適切なものが選択される。整流網および拡風板は空気槽内の風速を均一化するために設置している。風量の調節はパワーコントローラにより行う。測定時には、空気槽の静圧が換気レジスタの風量を測定するときの静圧に等しくなる(静圧0になる)ように調整した後、風量を測定する記録計(例えば、(株)岡野製作所製マノメータ)により、空気槽と測定用管路との差圧を読み取る。 (Example 1: Examination of pressure loss of ventilation register using nanofiber)
