Abstract
Description
本発明は、静翼付き送風機（静翼付き撹拌扇、静翼付きファン、静翼付き循環扇）の風胴（ドラム）と静翼構造に関する。 The present invention relates to a wind tunnel (drum) and a stationary blade structure of a blower with a stationary blade (agitating fan with a stationary blade, a fan with a stationary blade, and a circulation fan with a stationary blade).
従来、この種の送風機において、その吐出口側（吹出口側）に風胴を配し、この風胴内に、複数枚の静翼板を内設した静翼を取付ける。その通常の構造は、風胴の内面（内側）に、静翼の環状外郭体を支持する。その理由は、例えば、簡便性と作業の容易化等の観点からと考えられる。 2. Description of the Related Art Conventionally, in this type of blower, a wind tunnel is provided on the discharge port side (blower port side), and a stationary blade having a plurality of stationary blade plates is installed in the wind tunnel. The usual structure supports the annular outer body of a stationary blade on the inner surface (inner side) of the wind tunnel. The reason is considered from the viewpoints of, for example, simplicity and ease of work.
しかし、この環状外郭体は、風胴の内面に突出する。この突出した外郭体の厚みが、例えば、風胴内の送風の邪魔（抵抗物）となる。例えば、風胴内の内面近傍での乱流発生と、又は風胴内の送風の流速（速度）・風量等の低下と、その他吐出方向への風の流れにおいて、悪影響を与えること、等の問題を抱えている。また、騒音発生の要因となる。従って、これらの改良が要望される状況となってきた。 However, the annular outer body projects on the inner surface of the wind tunnel. The thickness of the protruding outer body becomes an obstacle (resistor) for blowing air in the wind tunnel, for example. For example, the generation of turbulent flow near the inner surface of the wind tunnel, or the decrease in the flow rate (speed), air volume, etc. of the air flow in the wind tunnel, and other adverse effects on the flow of wind in the discharge direction, etc. I have a problem. Moreover, it becomes a factor of noise generation. Therefore, these improvements have been demanded.
また、ノズルの風胴（外筒）内に、環状外郭体（内筒）を設ける構造に関して、特開２００９−２５７１４３号公報（文献（１））に記載の「気流ノズル」がある。しかしながら、この発明は、内外筒の構造であるが、発明の名称の如く、「ノズル」であり、静翼付送風機ではない。 Moreover, regarding a structure in which an annular outer body (inner cylinder) is provided in the wind tunnel (outer cylinder) of the nozzle, there is an “air flow nozzle” described in Japanese Patent Laid-Open No. 2009-257143 (reference (1)). However, although this invention is a structure of an inner and outer cylinder, as the name of the invention, it is a “nozzle” and not a fan with a stationary blade.
次に、送風機の風胴に内筒を設けた構造に関して、実開昭４９−５０８１０号公報（文献（２））に記載の「軸流送風機」とかにおいて、知られている。しかしながら、この考案は、内外筒の間に静翼を設けた構造であり、内筒には、静翼がなく、遠方への送風には、課題を残している。尚、内筒を収れんし、遠方への送風を意図するが、それ程の効果は期待できないものと考えられる。また、この考案は、静翼を、外筒内面と内筒外面との間に設けた構造であり、かつ静翼のピッチを異にするが、静翼効果と内筒の収れん効果とが、十分に機能していないと考えられる。 Next, a structure in which an inner cylinder is provided on the wind tunnel of a blower is known in “Axial flow blower” described in Japanese Utility Model Publication No. 49-50810 (reference (2)). However, this device has a structure in which a stationary blade is provided between the inner and outer cylinders, and the inner cylinder does not have a stationary blade, and a problem remains in blowing air far away. Although the inner cylinder is converged and intended to send air far away, it is considered that such an effect cannot be expected. In addition, this device is a structure in which the stationary blade is provided between the inner surface of the outer cylinder and the outer surface of the inner cylinder, and the pitch of the stationary blade is different, but the effect of the stationary blade and the convergence effect of the inner tube are It seems that it is not functioning well.
従来の如く、風胴の内面に、静翼の外郭体を取付ける構造では、前述した、外郭体が抵抗物となり、例えば、乱流発生と、又は風胴内を流れる風の流速・風量等と、その他吐出方向への風の流れにおいて、悪影響を与えること、等が考えられる。 As in the prior art, in the structure in which the outer body of the stationary blade is attached to the inner surface of the wind tunnel, the outer body becomes a resistor, for example, the occurrence of turbulent flow or the flow velocity / air volume of the wind flowing in the wind tunnel. In addition, other adverse effects can be considered in the flow of wind in the discharge direction.
また、従来の文献では、遠方への送風を意図した工夫が、随所に設けられているが、整流の生成に関する配慮、及び／又は、整流の生成に関しては、必ずしも、十分とは考えられない。また、整流の生成と、送風の遠方への送達を、十分で、かつ正確に達成するには、更なる改良が考えられる。 Further, in the conventional literature, a device intended to blow air far away is provided everywhere, but it is not necessarily considered sufficient for consideration regarding generation of rectification and / or generation of rectification. Also, further improvements are conceivable in order to achieve commutation generation and delivery of the blast far away sufficiently and accurately.
前記改良を解消し、さらに有効性を確保しつつ、翼（ファン）の風を、静翼で整流することと、この風の風量が収束する風胴の内面に、抵抗物、例えば、従来の静翼の外郭体を無くし、ファンの風を、効率的に、かつ整流を壊すことなく、風胴より吐出すること、又は整流が確保された風（整流風）を、遠方に向かって送風すること、等を意図して、請求項１〜５を提供する。 While eliminating the improvement and further ensuring the effectiveness, the wing (fan) wind is rectified by a stationary blade, and the inner surface of the wind tunnel where the wind volume converges, for example, a resistor, for example, The outer body of the stationary blade is eliminated, and the fan wind is discharged from the wind tunnel efficiently and without breaking the rectification, or the rectified wind (rectification wind) is blown away. Claims 1 to 5 are intended.

以下、本発明の好ましい一例を説明する。 Hereinafter, a preferable example of the present invention will be described.
図中１は送風機で、図１〜図５に示してある。その要部の構成は、モータ２と、このモータ２のフランジ（図示せず）に取付けられた線材で構成したガード３（保護網）と、モータ２の出力軸２００に支持したファン５とを主構成とする。ガード３のモータ側の環状線材３００が小径で、反モータ側の環状線材３０１が大径に構成されている。図中３０２はガード３の枠線材を示している。 In the figure, reference numeral 1 denotes a blower, which is shown in FIGS. The configuration of the main part includes a motor 2, a guard 3 (protective net) made of a wire attached to a flange (not shown) of the motor 2, and a fan 5 supported on the output shaft 200 of the motor 2. Main structure. The annular wire 300 on the motor side of the guard 3 has a small diameter, and the annular wire 301 on the non-motor side has a large diameter. In the figure, reference numeral 302 denotes a frame wire of the guard 3.
送風機１による風の発生と、送風を説明すると、モータ２の駆動でファン５が回転すると、このファン５の回転で、風が発生する（起こる）。風は後方Ａ（モータ側）より前方Ｂ（吐出方向で、風胴側）に向かって送風される。図中６は、ガード３に設けた吊り金具で、本発明の重心位置にあるガード３の環状線材３０３に設けられるとともに、この線材３０３の放射方向に突設されている。図１３の如く、建屋Ｈ（ハウス、工場等）の梁等の躯体に金具６００を利用して、簡易に安心して取付けできること、又は水平に、安定設置ができる。 The generation of wind by the blower 1 and the blowing of air will be described. When the fan 5 is rotated by driving the motor 2, wind is generated (occurs) by the rotation of the fan 5. The wind is blown from the rear A (motor side) toward the front B (discharge direction, wind tunnel side). In the figure, reference numeral 6 denotes a hanging metal fitting provided on the guard 3, which is provided on the annular wire 303 of the guard 3 at the center of gravity of the present invention, and protrudes in the radial direction of the wire 303. As shown in FIG. 13, it is possible to simply and safely attach the metal frame 600 to a frame such as a beam of the building H (house, factory, etc.), or to perform stable installation horizontally.
図中７は風胴で、この一例では環状（筒状）である。風胴７の内部（内面７ａ）には、数本の支持体８、８（ブラケット）を介して静翼１０が支持されている。また、この静翼１０は、この一例では環状（筒状）であり、風胴７より小径の環状（一例）の外郭体１０ａと、外郭体１０ａ内に数枚設けた渦巻き形状の静翼板１０ｂとで構成されている。 In the figure, reference numeral 7 denotes a wind tunnel, which is annular (tubular) in this example. A stationary blade 10 is supported inside the wind tunnel 7 (inner surface 7a) via several supports 8, 8 (brackets). In addition, the stationary blade 10 has an annular shape (tubular shape) in this example, and has an annular outer shape body 10a having a smaller diameter than the wind tunnel 7 and a spiral shaped stationary blade plate provided in the outer shape body 10a. 10b.
本発明では、風胴７の内面７ａには、環状空間１１を形成するようにして静翼１０が支持されており、この環状空間１１は内面７ａと静翼１０の外郭体１０ａとで形成された空間であり、かつ環状形状が相当する。この環状空間１１は、風速分布において、ファン５からの風量が最大に供給される領域であり、ここに環状空間１１の役割があり、かつこの環状空間１１が、ファン５の羽根の先部に位置していることに有効性がある。また、この環状空間１１の風胴７に占める位置と面積比にもあると考えられる。そして、望ましくは、ファン５の先端５ａに、静翼１０の外郭体１０ａが位置する構成として、支持体８で支持する。 In the present invention, the stationary blade 10 is supported on the inner surface 7 a of the wind tunnel 7 so as to form an annular space 11, and the annular space 11 is formed by the inner surface 7 a and the outer body 10 a of the stationary blade 10. It corresponds to an annular shape. The annular space 11 is a region where the air volume from the fan 5 is supplied to the maximum in the wind speed distribution. The annular space 11 has a role of the annular space 11, and the annular space 11 is at the tip of the blade of the fan 5. It is effective to be located. Further, it is considered that the annular space 11 occupies the position of the wind tunnel 7 and the area ratio. Desirably, the outer body 10a of the stationary blade 10 is positioned at the tip 5a of the fan 5 and is supported by the support body 8.
風胴７の基端側７ｂ（ファン側）には複数の支持具１２が取付けられており、この支持具１２は、風胴７に固定する支持具本体１２ａと、支持具本体１２ａの先端に設けた折曲げ係止部１２ｂとで構成されており、この折曲げ係止部１２ｂが、例えば、大径のガード３の環状線材３０１に係止される。この係止で、送風機１に風胴７が、安定して取付けられるとともに、必要時には、環状線材３０１を押圧、及び／又は、折曲げ係止部１２ｂを反り返して、環状線材３０１から折曲げ係止部１２ｂを外すことで、離脱できる。 A plurality of support tools 12 are attached to the base end side 7b (fan side) of the wind tunnel 7, and the support tools 12 are fixed to the wind tunnel 7 at the front end of the support tool main body 12a. For example, the bent locking portion 12b is locked to the annular wire 301 of the guard 3 having a large diameter. With this locking, the wind tunnel 7 is stably attached to the blower 1 and, when necessary, the annular wire 301 is pressed and / or the bending locking portion 12b is bent back to bend the annular wire 301. It can detach | leave by removing the latching | locking part 12b.
以下、本発明の風の流れを説明すると、ファン５が回転して、風が起こる（送風される）。送風は、風胴７の基端側７ｂから吐出側７ｃに向かって押出される（流れる）。この際に、風胴７の内面７ａには、障害物がなく、乱気流の発生がない。従って、送風がスムーズに流れることと、風速低下もなく、遠方への到達が期待できる。さらに、前述の如く、環状空間１１の存在で、ファン５からの風量が最大に供給される（この環状空間１１は、風胴７に送り込まれた風の道として活用できる）。これらの総合的な効果により、例えば、利用分野の拡充が図れる。また、この総合的な効果に併せて、従来のような騒音発生も少なく、利用分野の拡充が図れる。 Hereinafter, when the flow of the wind of the present invention is described, the fan 5 rotates and wind is generated (blowed). The blown air is pushed out (flows) from the base end side 7b of the wind tunnel 7 toward the discharge side 7c. At this time, there is no obstacle on the inner surface 7a of the wind tunnel 7, and no turbulence is generated. Therefore, it can be expected that the air flows smoothly and that the wind speed does not decrease and reach far away. Furthermore, as described above, the air volume from the fan 5 is supplied to the maximum due to the presence of the annular space 11 (this annular space 11 can be used as a path of wind sent into the wind tunnel 7). With these comprehensive effects, for example, the field of use can be expanded. In addition to this comprehensive effect, there is little noise generation as in the prior art, and the application field can be expanded.
