Description

本発明は、空調設備において室内のエアの吹出し口に設けられるソックダクトに関する。   The present invention relates to a sock duct provided at an air outlet in an air conditioner.

従来の空調設備では、室内のエアの吹出し口付近だけ直接に冷気等があたって人に不快感を生じさせたり、室内温度にむらを生じやすいという問題点があった。また、食製品の表面が乾燥したり、塵や埃が舞う等の問題点があった。
このような問題点を解消するため、特許文献１に記載されているように、ソックダクト（ソックスダクト、ソックフィルターとも呼ばれる。）をエアの吹出し口に取り付けることが行われている。
上記ソックダクトは、布地や不織布を素材とし、先端が閉塞された円筒状の袋体に形成され、その開口部側をエアの吹出し口に取り付けるとともに、全体を天井部から吊り下げることにより使用される。開口部側から冷気や暖気を圧力をかけてソックダクト内へ送り込み、ソックダクトの全表面からエアを放出させることにより、風を感じにくく、快適で温度むらの少ない室内環境が得られ、また、食製品の乾燥が防止され、塵や埃も捕捉されて衛生的であるという効果が得られる。
しかし、従来のソックダクトは、空調機の使用時にはソックダクトに内圧がかかっているためピンと張って膨らんだ筒状であるが、空調機を使用しないときは、ソックダクトに内圧がかかっていないため、ソックダクトが弛緩して萎んでしまい、外観上体裁が悪いという問題があった。同様に低風量時においてもソックダクトが形状を維持できず、気流の拡散性に懸念があった。
また、空調機停止時に内圧がかからなくなると、稼動時の断面円形が萎んで上下方向に細長い扁平な断面形状となり、ダクトの内面全体に付着した埃が落ちて最も窪んだ底部に溜まる。これを毎日繰り返すことにより、部分的に埃の層が厚くなり、細菌が発生しやすい環境を形成することとなり、衛生上好ましくないという問題があった。
このような問題を解決するための技術として、特許文献２には、「一端が閉塞され、他端に開口部を備えた、筒状の可撓性フィルター本体と、該可撓性フィルター本体の外面のほぼ全体を覆う、通気性を有する不燃性の形状保持部材とを備えたソックフィルター。」が開示されている。同文献には、通気性を有する不燃性の形状保持部材として、金網（金属製メッシュ）やパンチングメタル等の金属製素材が記載されている。
上記のような通気性を有する金属製素材は、火災時の火炎伝播を防止する必要があるため、金網等の網目は、０．１ｍｍ以下が好適であるが、重量が嵩み、取扱い・施工等に負担がかかる。また、金網等を筒状にするには手工業的な要素が多く、量産化が困難なため、コスト高となりやすい。さらに、一度変形すると、形状が元に戻りにくいため、美観上、使用が困難な場合もある。 In conventional air conditioning equipment, there is a problem that cold air or the like is directly applied only in the vicinity of the air outlet of the room, causing uncomfortable feelings to the person or causing unevenness in the room temperature. In addition, there are problems such as the surface of food products being dried and dust and dust flying.
In order to solve such problems, as described in Patent Document 1, a sock duct (also referred to as a sock duct or a sock filter) is attached to an air outlet.
The sock duct is made of a cloth or non-woven fabric and is formed in a cylindrical bag whose tip is closed. The sock duct is attached to the air outlet and is suspended from the ceiling. . Cold and warm air is sent from the opening side into the sock duct under pressure, and air is released from the entire surface of the sock duct, making it possible to create a comfortable indoor environment with less wind and less temperature fluctuations. Is prevented from being dried, and dust and dust are trapped and the effect of being hygienic is obtained.
However, the conventional sock duct has a cylindrical shape that is tightly inflated because the internal pressure is applied to the sock duct when the air conditioner is used, but when the air conditioner is not used, the sock duct is not subject to the internal pressure. There was a problem that it loosened and wilted, and the appearance was bad. Similarly, the sock duct could not maintain its shape even when the air volume was low, and there was concern about the diffusibility of the air flow.
Further, when the internal pressure is not applied when the air conditioner is stopped, the cross-sectional circular shape at the time of operation is deflated and becomes a flat cross-sectional shape elongated in the vertical direction. By repeating this every day, the dust layer partially thickens and forms an environment in which bacteria are likely to be generated, which is unfavorable for hygiene.
As a technique for solving such a problem, Patent Literature 2 discloses that a tubular flexible filter body having one end closed and an opening at the other end, and the flexible filter body A sock filter including a breathable non-flammable shape retaining member that covers substantially the entire outer surface. In this document, a metal material such as a wire mesh (metal mesh) or a punching metal is described as a nonflammable shape retaining member having air permeability.
Since the metal material having air permeability as described above needs to prevent flame propagation at the time of fire, the mesh of the wire mesh or the like is preferably 0.1 mm or less, but the weight is heavy, handling and construction. Burdens. In addition, there are many hand-crafted elements for making a wire mesh or the like into a cylindrical shape, and it is difficult to mass-produce, so that the cost tends to increase. Furthermore, once deformed, the shape is difficult to return to, so it may be difficult to use aesthetically.

FIG. 3 is a perspective view schematically showing the shape holding member 20.
The shape holding member 20 includes a cylindrical body 22 formed in a cylindrical shape by spirally winding edges of a sheet 21 having a predetermined width having air permeability, and an edge of the sheet 21 of the cylindrical body 22. And a spiral member 30 having a required rigidity, which is fixed at a position where the portions overlap.
The shape holding member 20 is formed to have air permeability and to have rigidity capable of holding the state when the wind pressure is present even if the wind pressure by the air conditioner decreases or disappears.

図４〜６は、螺旋部材３０のシート２１への固定態様を例示するものである。これらは何れも公知の態様である。
図４の例は、螺旋状に巻き回される所定幅のシート２１の縁部が重なり合って接着される位置に、螺旋部材３０（鋼線等）が内包されているものである。
図５、図６は、螺旋部材３０として、ほぼ断面Ｃ字状の、亜鉛めっき鋼板、鉄等の金属製連続性薄板により形成されたものを用い、このＣ字部分内にシート２１が挟み込まれることによって、螺旋部材がシート２１に直接に固定され、一体化された態様を示すものである。
図５の例では、所定幅のシート２１の縁部分が重なり合うように螺旋状に巻き回されて形成され、この重なり合う部分において、螺旋部材３０のＣ字部分内にシート２１が挟み込まれるとともに、さらにシート２１の内面側から螺旋部材３０のＣ字部分内に線部材３２が挿入されることにより、螺旋部材３０とシート２１とが一体化される。
線部材３２がＣ字部分内に挿入され、係止されることにより、螺旋部材３０がシート２１をしっかりと噛み、螺旋部材３０がシート２１から外れにくくなる。線部材３２は、通常、鉄線、亜鉛めっき鋼線等、弾性を有する金属材あるいはナイロンその他の合成樹脂材により構成される。
図６の例では、所定幅のシート２１の縁部分が重なり合うように螺旋状に巻き回されて形成されてはいるが、所定幅のシート２１の一方の縁部分が線部材３２をくるんで外面に折り返され、折り返し部分２１ａを形成しており、この折り返し部分２１ａの上（外面）に、シート２１の他方の縁部分が重ね合わせられて、螺旋状に巻き回されており、シート２１の縁部分が重ね合わせられた状態で、シート２１と線部材３２とが、螺旋部材３０のＣ字部分内に挟み込まれ、これにより螺旋部材３０とシート２１とが一体化されている。
上記螺旋部材３０の管本体２への固定方法は、定法により行うことができる。 4 to 6 exemplify how the spiral member 30 is fixed to the sheet 21. These are all known embodiments.
In the example of FIG. 4, a spiral member 30 (steel wire or the like) is included at a position where the edges of the sheet 21 having a predetermined width wound spirally overlap and adhere.
5 and 6, the spiral member 30 is formed of a continuous thin metal plate such as a galvanized steel plate or iron having a substantially C-shaped cross section, and the sheet 21 is sandwiched in the C-shaped portion. Thus, the spiral member is directly fixed to the sheet 21 and shows an integrated form.
In the example of FIG. 5, the sheet 21 having a predetermined width is formed by being spirally wound so that the edge portion overlaps, and the sheet 21 is sandwiched in the C-shaped portion of the spiral member 30 in the overlapping portion, and further, By inserting the line member 32 into the C-shaped portion of the spiral member 30 from the inner surface side of the sheet 21, the spiral member 30 and the sheet 21 are integrated.
When the wire member 32 is inserted into the C-shaped portion and locked, the spiral member 30 firmly bites the sheet 21, and the spiral member 30 is unlikely to come off the sheet 21. The wire member 32 is usually made of an elastic metal material such as iron wire or galvanized steel wire, or nylon or other synthetic resin material.
In the example of FIG. 6, the sheet 21 having a predetermined width is formed by being spirally wound so that the edge portions overlap each other. The other edge portion of the sheet 21 is overlapped on the folded portion 21a (outer surface) and wound spirally, and the edge of the sheet 21 is folded. In a state where the portions are overlapped, the sheet 21 and the line member 32 are sandwiched between the C-shaped portions of the spiral member 30, and thereby the spiral member 30 and the sheet 21 are integrated.
The method for fixing the helical member 30 to the tube body 2 can be performed by a conventional method.

また、上記の、螺旋状に巻き回して筒状に形成した筒状体２２と螺旋部材３０を用いた形状保持部材の構造に代えて、次のような構造を採用することができる（図７参照）。
通気性を有する所定幅のシートを巻き回し、その幅方向の両側縁部分を接合して、筒状体２２に形成する。そして、該筒状体２２の外表面に沿う、所要の剛性を備えたリング状部材（鋼線等からなる。）３５を該筒状体２２の長手方向に適宜間隔をおいて複数個、固定する。リング状部材３５の筒状２２体への固定は、接着、溶着のほか、リング状部材３５の上にテープを被せて該テープを筒状体２２に固着すること等により行うことができる。
この場合、筒状体２２は軸方向には収縮し得るが、ソックダクトを吊り下げて使用する場合において筒状体２２の軸方向の形状保持は不要であり、径方向の形状は保持されるため、空調機停止時等にソックダクトが弛緩して萎むことはない。もっとも、各リング状部材３５を適宜連結部材を用いて連結すること等により、軸方向の形状を保持することも可能である。 In addition, the following structure can be adopted instead of the structure of the shape holding member using the cylindrical member 22 and the spiral member 30 that are spirally wound and formed into a cylindrical shape (FIG. 7). reference).
A sheet having a predetermined width having air permeability is wound, and both side edge portions in the width direction are joined to form the cylindrical body 22. Then, a plurality of ring-shaped members (made of steel wire or the like) 35 having required rigidity along the outer surface of the cylindrical body 22 are fixed at appropriate intervals in the longitudinal direction of the cylindrical body 22. To do. The ring-shaped member 35 can be fixed to the cylindrical body 22 by adhering or welding, or by covering the ring-shaped member 35 with a tape and fixing the tape to the cylindrical body 22.
In this case, the cylindrical body 22 can contract in the axial direction, but when the sock duct is suspended and used, it is not necessary to maintain the axial shape of the cylindrical body 22, and the radial shape is maintained. The sock duct does not relax and deflate when the air conditioner is stopped. But it is also possible to hold | maintain the shape of an axial direction by connecting each ring-shaped member 35 using a connection member suitably.

形状保持部材２０に用いられるシート２１としては、外面形成部材１０について説明したのと同様の、通気性を有する可撓性素材を用いることができる。通常、形状保持部材２０の筒状体２２を形成するシート２１は、複数層ではなく単層の一枚のシート材により構成される。   As the sheet 21 used for the shape holding member 20, a flexible material having air permeability similar to that described for the outer surface forming member 10 can be used. Usually, the sheet | seat 21 which forms the cylindrical body 22 of the shape holding member 20 is comprised by the sheet material of one sheet of a single layer instead of multiple layers.

＜外面形成部材と形状保持部材との関係＞
外面形成部材１０の少なくとも一つの層と、形状保持部材２０を構成するシート２１のうち、少なくとも一方は前述の不燃性素材で構成される。
また、外面形成部材１０は、形状保持部材２０に対して取り外し可能に被せることにより、形状保持部材２０の外周を被覆して設けられる。すなわち、筒状に形成した外面形成部材１０の中に形状保持部材２０を挿入することにより、形状保持部材２０の外面のほぼ全体が外面形成部材１０で覆われ、ソックダクト１を構成する。したがって、外面形成部材１０と形状保持部材２０とは互いに着脱可能であり、かつ着脱容易である。
外面形成部材１０の内寸は、不燃性の形状保持部材２０の外寸より僅かに大きく形成され、外面形成部材１０の内側に形状保持部材２０挿入しやすくする。 <Relationship between outer surface forming member and shape retaining member>
At least one of at least one layer of the outer surface forming member 10 and the sheet 21 constituting the shape maintaining member 20 is made of the above-described nonflammable material.
The outer surface forming member 10 is provided so as to cover the outer periphery of the shape holding member 20 by covering the shape holding member 20 so as to be removable. That is, by inserting the shape retaining member 20 into the outer surface forming member 10 formed in a cylindrical shape, almost the entire outer surface of the shape retaining member 20 is covered with the outer surface forming member 10 to constitute the sock duct 1. Therefore, the outer surface forming member 10 and the shape maintaining member 20 can be attached to and detached from each other and are easily attached and detached.
The inner dimension of the outer surface forming member 10 is formed slightly larger than the outer dimension of the nonflammable shape retaining member 20, so that the shape retaining member 20 can be easily inserted inside the outer surface forming member 10.
