Description

本発明は、建築物の天井裏などに架設される空調用ダクトに介在して配置される風量調整ユニットに関する。   The present invention relates to an air volume adjusting unit that is disposed in an air conditioning duct installed on the ceiling or the like of a building.

空調用ダクト内を流れる空気流の風量を調整するために配置される風量調整ユニットは一般に鋼板で形成され、内蔵された開閉羽根には特に消音手段は講じられていないものが多い。このため、風量調整ユニットで発生する騒音(特に、開閉羽根部分で発生する風切り音)は、その下流に位置する室内吹出口を経由して室内へ伝播することが多かった。そこで、風量調整ユニットの下流側に、別途、消音器(消音ボックス)を設置することにより、風量調整ユニットで発生する騒音を吸収し、室内へ伝播するのを防止していた。   An air volume adjusting unit arranged for adjusting the air volume of the airflow flowing through the air conditioning duct is generally formed of a steel plate, and many built-in opening and closing blades are not particularly provided with a silencing means. For this reason, noise generated by the air volume adjusting unit (particularly wind noise generated at the opening and closing blades) often propagates indoors via the indoor outlet located downstream thereof. Therefore, by installing a silencer (silence box) separately on the downstream side of the air volume adjustment unit, noise generated by the air volume adjustment unit is absorbed and prevented from propagating indoors.

一方、消音器(消音ボックス)を使用せず、風量調整ユニット自体に消音機能を持たせたものがある(例えば、特許文献1参照。)。特許文献1記載の風量調整装置は、風路を横断して回動可能に設けられたダンパ板に、複数の開口を分散配置するとともに、ダンパ板の表面に消音材を付着させることにより、騒音(風切り音)の発生を抑制するものである。   On the other hand, there is one in which the silencer (silence box) is not used and the air volume adjusting unit itself has a silencing function (for example, see Patent Document 1). In the air volume adjusting device described in Patent Document 1, a plurality of openings are dispersedly arranged on a damper plate that can be rotated across an air passage, and a noise-reducing material is attached to the surface of the damper plate, thereby reducing noise. (Wind noise) is suppressed.

実開平4−103553号公報Japanese Utility Model Publication No. 4-103553

消音手段として消音器(消音ボックス)を用いた場合、風量調整ユニット以外に当該消音器を設置しなければならないので、限られた領域内にその設置スペースを確保する必要があるだけでなく、施工の煩雑化の要因となっている。   When a silencer (silence box) is used as a silencer, the silencer must be installed in addition to the air volume adjustment unit, so it is not only necessary to secure the installation space in a limited area, It becomes a factor of complication.

特許文献1記載の風量調整装置の場合、複数の開口が分散配置されたダンパ板の表面に消音材を付着させた複雑な構造であるため、その組立工程においては多大な手間と時間を必要とし、組立の煩雑化を招いている。   In the case of the air volume adjusting device described in Patent Document 1, since it has a complicated structure in which a silencer is attached to the surface of a damper plate in which a plurality of openings are dispersedly arranged, the assembly process requires a great deal of labor and time. As a result, the assembly is complicated.

本発明が解決しようとする課題は、シンプルな構造で、組立および施工が容易であり、騒音を低減できる風量調整ユニットを提供することにある。   The problem to be solved by the present invention is to provide an air volume adjusting unit that has a simple structure, is easy to assemble and install, and can reduce noise.

本発明の風量調整ユニットは、空調用ダクトに接続され内部に流路を形成する筒状のケーシングと、前記流路を開閉するため前記ケーシング内に設けられた開閉羽根と、前記開閉羽根の外面の少なくとも一部に付設された通気性部材と、を備えたことを特徴とする。   An air volume adjusting unit according to the present invention includes a cylindrical casing that is connected to an air conditioning duct and forms a flow channel therein, an open / close blade provided in the casing for opening and closing the flow channel, and an outer surface of the open / close blade And a breathable member attached to at least a part of this.

このような構成とすれば、流路内を流れる気流により開閉羽根の端部付近で発生する比較的大きなカルマン渦は、開閉羽根に設けられた通気性部材によって拡散され、小さな渦となって、その勢いが減衰されるため、発生した騒音を低減することができる。また、開閉羽根の少なくとも一部に通気性部材を設けただけのシンプルな構造であるため、組立が容易であり、別途、消音器を設ける必要がないので、施工も容易である。   With such a configuration, the relatively large Karman vortex generated near the end of the opening and closing blade by the airflow flowing in the flow path is diffused by the air-permeable member provided in the opening and closing blade, and becomes a small vortex, Since the momentum is attenuated, the generated noise can be reduced. Moreover, since it is a simple structure which provided only the air permeable member in at least one part of the opening-and-closing blade, an assembly is easy and it is not necessary to provide a silencer separately, and construction is also easy.

ここで、前記通気性部材の一部を前記開閉羽根の外周より突出させて付設することが望ましい。このような構成とすれば、特に比較的大きなカルマン渦が発生しやすい、開閉羽根の外周部分における騒音抑制作用が高まるため、騒音をさらに低減することができる。   Here, it is desirable to attach a part of the air-permeable member so as to protrude from the outer periphery of the opening / closing blade. With such a configuration, since the noise suppressing action at the outer peripheral portion of the opening / closing blade is increased, in particular, a relatively large Karman vortex is likely to be generated, noise can be further reduced.

この場合、前記通気性部材として、合成繊維製のフィルタ材を用いれば、当該フィルタ材が優れた気流拡散作用を発揮するため、騒音の低減に有効である。このようなフィルタ材としては、繊維を編まずに構成された通気性を有する不織布製のフィルタ材などが好適である。不織布製のフィルタ材は、その通気する部分が織布製のフィルタ材のように均一でなく、目の粗さも揃っていないため、気流拡散作用が良好である。なお、フィルタ材は難燃性または不燃性を有するものが好適である。   In this case, if a synthetic fiber filter material is used as the air permeable member, the filter material exhibits an excellent air flow diffusing action, which is effective in reducing noise. As such a filter material, a non-woven filter material made of a non-woven fabric that is constructed without knitting fibers is suitable. The non-woven filter material has a good air flow diffusing action because the air-permeable portion is not uniform and the roughness of the eyes is not uniform, unlike the filter material made of woven fabric. In addition, what has a flame retardance or a nonflammability is suitable for a filter material.

また、前記フィルタ材を構成する合成繊維の飛散防止手段を設ければ、フィルタ材の効果を維持しつつフィルタ材を構成する繊維が飛散するのを防止することができる。なお、飛散防止手段としては、フィルタ材よりも目が細かく、通気性を有する不織布によってフィルタ材の表面を被覆するなどの手段をとることができる。   Moreover, if the synthetic fiber scattering prevention means which comprises the said filter material is provided, it can prevent that the fiber which comprises a filter material splashes, maintaining the effect of a filter material. In addition, as a scattering prevention means, means such as covering the surface of the filter material with a non-woven fabric which is finer than the filter material and has air permeability can be used.

本発明により、シンプルな構造で、組立および施工が容易であり、騒音を低減できる風量調整ユニットを提供することができる。   According to the present invention, it is possible to provide an air volume adjusting unit that has a simple structure, can be easily assembled and installed, and can reduce noise.

以下、図面に基づいて、本発明の実施の形態について説明する。図1は本発明の実施の形態である風量調整ユニットを示す正面図、図2は図1に示す風量調整ユニットの側面図、図3は図1に示す風量調整ユニットを構成する開閉羽根を示す図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a front view showing an air volume adjusting unit according to an embodiment of the present invention, FIG. 2 is a side view of the air volume adjusting unit shown in FIG. 1, and FIG. 3 shows open / close blades constituting the air volume adjusting unit shown in FIG. FIG.

図1〜図3に示すように、本実施形態の風量調整ユニット10は、空調用ダクト22に接続され内部に流路を形成する円筒状のケーシング11と、前記流路を開閉するためケーシング11内に設けられた開閉羽根14と、開閉羽根14の外面(表裏両面)に付設された消音材24と、を備えている。開閉羽根14は一枚の略円形体からなり、その中心にシャフト13が取り付けられている。また、ケーシング11内を流れる空気流の風速を検出するプロペラ式の風速センサ12と、開閉羽根14を回転駆動する開閉装置15と、を備え、開閉羽根14は、シャフト13を中心に回転することによってケーシング11内の流路を開閉する。   As shown in FIGS. 1 to 3, the air volume adjustment unit 10 of the present embodiment includes a cylindrical casing 11 that is connected to an air conditioning duct 22 and forms a flow path therein, and a casing 11 that opens and closes the flow path. The opening / closing blade 14 provided in the inside and the sound deadening material 24 attached to the outer surface (front and back both surfaces) of the opening / closing blade 14 are provided. The opening / closing blade 14 is formed of a single substantially circular body, and a shaft 13 is attached to the center thereof. In addition, a propeller-type wind speed sensor 12 that detects the wind speed of the airflow flowing in the casing 11 and an opening / closing device 15 that rotationally drives the opening / closing blade 14 are provided. The opening / closing blade 14 rotates about the shaft 13. Thus, the flow path in the casing 11 is opened and closed.

風速センサ12は、ケーシング11の軸線方向の気流を受けて回転するプロペラ17と、プロペラ17より下流側においてプロペラ17を回転自在に支えるセンサケーシング18と、プロペラ17の回転数を検出するためセンサケーシング18内に設けられた非接触方式の検出部(図示せず)と、センサケーシング18の上流側の先端部外周を囲繞する状態でプロペラ17の回転中心に設けられたキャップ形状のハブ19と、を備えている。センサケーシング18の両側には、風速センサ12をケーシング11に固定するための取付具20が装着されている。   The wind speed sensor 12 includes a propeller 17 that rotates by receiving an airflow in the axial direction of the casing 11, a sensor casing 18 that rotatably supports the propeller 17 on the downstream side of the propeller 17, and a sensor casing for detecting the rotation speed of the propeller 17. A non-contact type detection unit (not shown) provided in 18, a cap-shaped hub 19 provided at the rotation center of the propeller 17 in a state of surrounding the outer periphery of the upstream end of the sensor casing 18; It has. On both sides of the sensor casing 18, a fixture 20 for fixing the wind speed sensor 12 to the casing 11 is mounted.

ケーシング11内を矢印方向に流れる空気流を受けてプロペラ17が回転すると、センサケーシング18内に配置された検出部が、プロペラ17と連動して回転する磁石(図示せず)による磁界の変化を検出し、その検出信号を、配線21を経由して開閉装置15へ伝送する。開閉装置15は、前記検出信号に基づいてシャフト13を回転駆動し、これによってケーシング11内の開閉羽根14が開閉する。   When the propeller 17 rotates in response to an air flow flowing in the direction of the arrow in the casing 11, the detection unit arranged in the sensor casing 18 changes the magnetic field by a magnet (not shown) that rotates in conjunction with the propeller 17. Then, the detection signal is transmitted to the switchgear 15 via the wiring 21. The opening / closing device 15 rotationally drives the shaft 13 based on the detection signal, whereby the opening / closing blade 14 in the casing 11 is opened / closed.

本実施形態の風量調整ユニット10においては、図3に示すように、消音手段として、開閉羽根14の外面(表裏両面)に、気流拡散機能を有する消音材24を付設している。このため、空調用ダクト22内で発生する渦はケーシング11内に進入して消音材24によって拡散され、ある程度、整流される。特に、開閉羽根14の外周部分で発生する比較的大きな渦(カルマン渦)は消音材24を通過することにより小さな渦に拡散、減衰されるため、騒音を低減することができる。また、開閉羽根14の外面に消音材24を付設したシンプルな構造であるため、組立は容易であり、別途、消音器を設ける必要がないので、施工も容易である。   In the air volume adjusting unit 10 of the present embodiment, as shown in FIG. 3, a silencer 24 having an airflow diffusion function is attached to the outer surface (both front and back surfaces) of the opening / closing blade 14 as a silencer. For this reason, the vortex generated in the air conditioning duct 22 enters the casing 11 and is diffused by the silencer 24 and is rectified to some extent. In particular, a relatively large vortex (Karman vortex) generated at the outer peripheral portion of the opening / closing blade 14 is diffused and attenuated into a small vortex by passing through the silencer 24, so that noise can be reduced. Moreover, since it is a simple structure which attached the silencer 24 to the outer surface of the opening-and-closing blade 14, an assembly is easy and it is not necessary to provide a silencer separately, and construction is also easy.

さらに、消音材24の外周部24aは、開閉羽根14の外周部14aより径方向に突出させて付設しているため、特に、比較的大きなカルマン渦が発生しやすい、開閉羽根14の外周部分における騒音を効率良く低減することができる。本実施形態では消音材24として、優れた気流拡散作用を有する合成繊維製不織布で構成された難燃性のフィルタ材を用いている。消音材24を構成する不織布製のフィルタ材は、その通気する部分が織布製のフィルタ材のように均一でなく、目の粗さも揃っていないため、気流拡散作用が良好であり、騒音の低減に有効であるが、これに限定するものではない。また、開閉羽根14の外面(表裏両面)に消音材24を付設しているが、これに限定するものではない。   Furthermore, since the outer peripheral portion 24a of the sound deadening material 24 is provided so as to protrude in the radial direction from the outer peripheral portion 14a of the opening / closing blade 14, a relatively large Karman vortex is likely to be generated, particularly in the outer peripheral portion of the opening / closing blade 14. Noise can be reduced efficiently. In the present embodiment, a flame retardant filter material composed of a synthetic fiber nonwoven fabric having an excellent air flow diffusing action is used as the silencer 24. The non-woven filter material constituting the sound deadening material 24 has a uniform air flow diffusing action because the air-permeable portion thereof is not uniform and the roughness of the eyes is not uniform as in the case of the woven filter material. Although effective for reduction, it is not limited to this. Moreover, although the sound deadening material 24 is attached to the outer surface (front and back both surfaces) of the opening-and-closing blade 14, it is not limited to this.

次に、図4,図5を参照して、消音手段に関するその他の実施形態について説明する。図4,図5は消音手段に関するその他の実施の形態を示す図である。なお、図4,図5にいて図1〜図3と同じ符号を付している部分は、前述した風量調整ユニット10の構成部分と同じ機能、効果を有する部分であり、説明を省略する。   Next, with reference to FIG. 4 and FIG. 5, another embodiment relating to the silencer will be described. 4 and 5 are diagrams showing other embodiments relating to the silencer. 4 and 5, the portions denoted by the same reference numerals as in FIGS. 1 to 3 are portions having the same functions and effects as the components of the air volume adjustment unit 10 described above, and the description thereof is omitted.

図4に示す実施形態においては、開閉羽根14の外面に付設された消音材24の外面を不織布25で被覆している。このような構成とすれば、消音材24を構成する合成繊維が流路内の流れる気流とともに飛散して、室内へ流入するのを防止することができる。   In the embodiment shown in FIG. 4, the outer surface of the silencer 24 attached to the outer surface of the opening / closing blade 14 is covered with a nonwoven fabric 25. With such a configuration, it is possible to prevent the synthetic fibers constituting the sound deadening material 24 from being scattered with the airflow flowing in the flow path and flowing into the room.

図5に示す実施形態においては、開閉羽根14より少し大きな半月形状の消音材26を二枚重ね合わせ、円弧状の外周部26aを固着して二つの袋状部材26xを形成し、これらの袋状部材26xの弦部26bから二枚の消音材26の間にそれぞれ開閉羽根14を差し込んで固定することにより、消音材26を開閉羽根14の外面に付設している。このような構成とすれば、風量調整ユニットの組立工程を簡易化することができる。また、袋状部材26xを開閉羽根14に着脱することによって消音材26のみの交換も可能となる。なお、袋状部材26xを開閉羽根14に固定する手段として、本実施形態ではエポキシ樹脂系の接着剤を用いているが、これに限定するものではない。   In the embodiment shown in FIG. 5, two half-moon silencers 26 that are slightly larger than the opening and closing blades 14 are overlapped, and the arc-shaped outer peripheral portion 26a is fixed to form two bag-like members 26x. These bag-like members The silencer 26 is attached to the outer surface of the opening / closing blade 14 by inserting and fixing the opening / closing blade 14 between the two silencers 26 from the 26x string portion 26b. With such a configuration, the assembly process of the air volume adjusting unit can be simplified. In addition, it is possible to replace only the silencer 26 by attaching / detaching the bag-like member 26x to the opening / closing blade 14. As a means for fixing the bag-like member 26x to the opening / closing blade 14, an epoxy resin adhesive is used in the present embodiment, but the present invention is not limited to this.

本発明の風量調整ユニットは、空調設備を構成する空調用ダクトなどの各種送風経路における風量制御手段として広く利用することができる。   The air volume adjusting unit of the present invention can be widely used as an air volume control means in various air blowing paths such as an air conditioning duct constituting an air conditioning facility.
