Abstract
Description
本発明の一実施形態は気流吐出ユニット及び流体機器に関する。 One embodiment of the present invention relates to an air flow discharge unit and a fluid device.
近年、流体素子を利用した機器が知られている。流体素子とは、流体（液体、気体）を作動体とする制御要素の総称である。可動部なしに流体の運動のみによって流体の制御を行なうものは特に純流体素子と呼ばれる。 In recent years, devices using fluidic elements are known. The fluid element is a general term for control elements having a fluid (liquid, gas) as an operating body. A device that controls a fluid only by the movement of the fluid without a moving part is particularly called a pure fluid element.
エアシャワー装置に取り付けられる純流体素子として、特許文献１に記載された技術が知られている。 As a pure fluid element attached to an air shower device, a technique described in Patent Document 1 is known.
特許文献１に記載された純流体素子は、流体流入口と、この流体流入口より流入した流体が横断する連結ダクトと、この連結ダクトを横断した流体が流出する流体噴出ノズルとを備え、噴出ノズルに流れる流体により生じた圧力差により連結ダクト内の流体を駆動し、この駆動によって発生した連結ダクト内の流体の流れによって噴出ノズルから流出する流体の流速が変動するようになっており、連結ダクトが、断面が曲線で構成された左右対称な２本の流路を有し、この２本の流路を、連結ダクトと流体流入口から流体噴出ノズルの間を流れる流体との合流点で合流させるものである。 The pure fluid element described in Patent Document 1 includes a fluid inlet, a connection duct through which a fluid flowing in from the fluid inlet crosses, and a fluid ejection nozzle through which the fluid crossing the connection duct flows out. The fluid in the connection duct is driven by the pressure difference generated by the fluid flowing in the nozzle, and the flow velocity of the fluid flowing out from the ejection nozzle is changed by the flow of fluid in the connection duct generated by this drive. The duct has two symmetrical flow paths each having a curved cross section, and the two flow paths are joined at a junction between the connecting duct and the fluid flowing between the fluid injection nozzle and the fluid ejection nozzle. It will be merged.
しかしながら、特許文献１に記載された技術では、気流の「揺らし」の効果や実感を得ることができないという問題があった。 However, the technique described in Patent Document 1 has a problem that it is impossible to obtain the effect and feeling of “swaying” the airflow.
例えば、手持ち型のドライヤーの場合、ユーザ自身が手動でドライヤー自体を上下又は左右に揺らすことでドライヤーからの風を上下又は左右に揺らしていた。これと同様の効果を気流の自励振動により得ようとする場合、気流を上下又は左右にゆっくりと揺らす必要があるが、特許文献１に記載された純流体素子ではこれを実現することが困難であった。すなわち、特許文献１に記載された純流体素子は除塵目的で用いることが意図され、大きく、強い気流が創出されてしまうので、叩くような気流となってしまい、気流の「揺らし」の効果や実感を得ることができなかった。 For example, in the case of a hand-held dryer, the user himself / herself manually shakes the dryer up / down or left / right to shake the wind from the dryer up / down or left / right. In order to obtain the same effect by self-excited vibration of the airflow, it is necessary to slowly shake the airflow up and down or left and right. However, it is difficult to achieve this with the pure fluid element described in Patent Document 1. Met. That is, the pure fluid element described in Patent Document 1 is intended to be used for dust removal, and creates a large and strong airflow, resulting in a slamming airflow, I couldn't get a real feeling.

The main body 110 may be any device that flows an air flow into the air flow discharge unit 120.
図１乃至図３に示すように、気流吐出ユニット１２０は、突出部１２６が本体１１０の風吹き出し口１１２に嵌合されて本体１１０に装着される。気流吐出ユニット１２０は、本体１１０から送られてくる気流の向きを変更させる機構を有する。気流吐出ユニット１２０の構造の詳細は後述する。 As shown in FIGS. 1 to 3, the airflow discharge unit 120 is mounted on the main body 110 with the protruding portion 126 fitted into the wind outlet 112 of the main body 110. The airflow discharge unit 120 has a mechanism for changing the direction of the airflow sent from the main body 110.

図４乃至図６に示すように、気流吐出ユニット１２０は、本体１１０の風吹き出し口１１２の先に取り付けて使用される。この例では、気流吐出ユニット１２０は、本体１１０の風吹き出し口１１２に直接取り付けて使用される例を示しているが、これに限られず、気流吐出ユニット１２０と本体１１０との間に他の部材を介在させて取り付けられるようにしてもよい。また、気流吐出ユニット１２０の本体１１０に対する取付角度（風吹き出し口１１２の中心の周りの相対角度）は、本実施形態で説明するものに限られず、本実施形態で説明する取付角度に対して±９０°の取付角度としてもよい。 As shown in FIGS. 4 to 6, the airflow discharge unit 120 is used by being attached to the tip of the wind outlet 112 of the main body 110. In this example, the airflow discharge unit 120 is used by being directly attached to the wind outlet 112 of the main body 110, but is not limited thereto, and other members are provided between the airflow discharge unit 120 and the main body 110. You may make it attach with interposition. Further, the mounting angle of the airflow discharge unit 120 with respect to the main body 110 (relative angle around the center of the wind outlet 112) is not limited to that described in the present embodiment, but is ± with respect to the mounting angle described in the present embodiment. It is good also as an attachment angle of 90 degrees.
図５に示すように、気流吐出ユニット１２０は、送風方向にわずかにテーパー形状に形成されている。しかし、気流吐出ユニット１２０は、送風方向に逆テーパー形状に形成してもよいし、円柱形状に形成してもい。 As shown in FIG. 5, the airflow discharge unit 120 is formed in a slightly tapered shape in the blowing direction. However, the airflow discharge unit 120 may be formed in a reverse taper shape in the blowing direction, or may be formed in a cylindrical shape.
図６に示すように、気流吐出ユニット１２０の縦方向の幅Ｗ１は、本体１１０の風吹き出し口１１２の縦方向の幅Ｗ２よりも大きく形成され、本体１１０の風吹き出し口１１２の縦方向の幅よりも気流吐出ユニット１２０の流出口１２４の縦方向の幅の方が大きくなるように形成される。 As shown in FIG. 6, the vertical width W <b> 1 of the airflow discharge unit 120 is formed larger than the vertical width W <b> 2 of the wind outlet 112 of the main body 110, and the vertical width of the wind outlet 112 of the main body 110.

図８は、本発明の一実施形態に係る流体機器の気流吐出ユニットの流出口側の構成を示す斜視図である。図９は、本発明の一実施形態に係る流体機器の気流吐出ユニットを流出口側からみた断面図である。
<Configuration of air flow discharge unit of fluid equipment>
[Outlet configuration]
FIG. 8 is a perspective view showing the configuration of the outlet side of the airflow discharge unit of the fluid device according to the embodiment of the present invention. FIG. 9 is a cross-sectional view of the airflow discharge unit of the fluid device according to the embodiment of the present invention as viewed from the outlet side.
図８に示すとおり、流出口１２４を規定する外周部１２３は、二箇所の凹部１２７を有する。二箇所の凹部１２７を設けることにより、後述する、上方及び下方への風向きの切り替えをよりスムーズに行うことができる。 As shown in FIG. 8, the outer peripheral portion 123 that defines the outflow port 124 has two concave portions 127. By providing the two concave portions 127, it is possible to smoothly switch the wind direction upward and downward, which will be described later.
すなわち、後述のとおり、本発明の一実施形態に係る流体機器の気流吐出ユニット１２０は、上部１４０に沿った気流Ｘと下部１４２に沿った気流Ｙを継続的に切り替えて気流を上下に揺らす。このとき、気流はコアンダ効果により壁に沿って進もうとする。そのため、左右に凹部１２７がなく左右にも壁が存在する場合には、気流Ｘ又は気流Ｙの一部は凹部１２７に代わって存する左右の壁に沿って進み、気流Ｘ又は気流Ｙが分散する。 That is, as will be described later, the airflow discharge unit 120 of the fluid device according to the embodiment of the present invention continuously switches between the airflow X along the upper portion 140 and the airflow Y along the lower portion 142 to swing the airflow up and down. At this time, the airflow tends to travel along the wall due to the Coanda effect. Therefore, when there are no recesses 127 on the left and right and there are walls on the left and right, part of the airflow X or airflow Y travels along the left and right walls in place of the recesses 127 and the airflow X or airflow Y is dispersed. .
そこで、本発明の一実施形態に係る流体機器の気流吐出ユニット１２０の流出口１２４においては、気流を揺らそうとする方向（この例では上下）に垂直な方向（この例では左右）に並びそれぞれ流入口１２２側に凹んだ一対の台形状の凹部１２７を上下方向中央部に備えるように外周部１２３を形成することで、気流を揺らそうとする方向と異なる方向への気流の分散を防ぎ、気流の揺らしの効果をより強く得ることができる。なお、凹部１２７を台形状に構成することは必須ではなく、三角形状に構成してもよく、Ｕ字形状に構成してもよい。また、気流を左右に揺らそうとする場合には、一対の凹部１２７が外周部１２３の左右方向中央部に上下方向に並ぶように、気流吐出ユニット１２０の本体１１０に対する取付角度を調整すればよい。 Therefore, at the outlet 124 of the airflow discharge unit 120 of the fluid device according to the embodiment of the present invention, each is arranged in a direction (left and right in this example) perpendicular to the direction in which the airflow is to be shaken (up and down in this example). By forming the outer peripheral portion 123 so as to have a pair of trapezoidal concave portions 127 recessed on the inflow port 122 side in the central portion in the vertical direction, it is possible to prevent dispersion of the airflow in a direction different from the direction in which the airflow is to be shaken, The effect of shaking the airflow can be obtained more strongly. Note that the concave portion 127 is not necessarily formed in a trapezoidal shape, and may be formed in a triangular shape or a U-shape. Further, when the airflow is to be swung left and right, the attachment angle of the airflow discharge unit 120 with respect to the main body 110 may be adjusted so that the pair of concave portions 127 are arranged in the vertical direction at the center in the left-right direction of the outer peripheral portion 123. .
図９に示すとおり、流出口１２４は楕円形状に形成される。断面でみたときの流出口１２４の面積Ａ２は、流入口１２２の面積Ａ１よりも大きくなっている。流出口１２４付近の気流吐出ユニット１２０の内壁は、流出口１２４に向かって逆テーパー形状に形成される。気流はコアンダ効果により壁に沿って進むため、気流吐出ユニット１２０をこのような形状とすることで、広く揺れる風を得ることができる。 As shown in FIG. 9, the outlet 124 is formed in an elliptical shape. The area A2 of the outlet 124 when viewed in a cross section is larger than the area A1 of the inlet 122. The inner wall of the airflow discharge unit 120 in the vicinity of the outlet 124 is formed in a reverse taper shape toward the outlet 124. Since the airflow travels along the wall due to the Coanda effect, a wide swaying wind can be obtained by forming the airflow discharge unit 120 in such a shape.

[Outlet configuration]
FIG. 10 is an exploded perspective view showing the inflow port of the air flow discharge unit of the fluid device according to the embodiment of the present invention.
図１０に示すように、気流吐出ユニット１２０の突出部１２６は、本体１１０からの気流が流入する流入口１２２となっている。この例では、突出部１２６は、ネジ止めにより流出口１２４側の部材と組み合わされ、気流吐出ユニット１２０の突出部１２６が本体１１０の風吹き出し口１１２に嵌合されることで、気流吐出ユニット１２０が本体１１０に装着される。 As shown in FIG. 10, the protrusion 126 of the airflow discharge unit 120 serves as an inflow port 122 into which the airflow from the main body 110 flows. In this example, the protrusion 126 is combined with a member on the outflow port 124 side by screwing, and the protrusion 126 of the airflow discharge unit 120 is fitted into the air outlet 112 of the main body 110, whereby the airflow discharge unit 120. Is mounted on the main body 110.

図１１は、本発明の一実施形態に係る流体機器の気流吐出ユニットの流入口側の構成を示す断面斜視図である。図１２は、本発明の一実施形態に係る流体機器の気流吐出ユニットの流入口側の断面図である。
[Configuration of internal flow path]
FIG. 11 is a cross-sectional perspective view showing the configuration on the inlet side of the airflow discharge unit of the fluid device according to the embodiment of the present invention. FIG. 12 is a cross-sectional view of the inlet side of the airflow discharge unit of the fluid device according to the embodiment of the present invention.
本発明の一実施形態に係る流体機器１００の気流吐出ユニット１２０は、流入口１２２の外周に沿って２本の流路２００を備える。流路２００は、複数のリブ２１０を含む壁部２３０により規定され、２箇所の開口部を有する。図１２に示すように、流路２００は、この例では、断面でみたときに左右に２本、略対称に備えられる。 The airflow discharge unit 120 of the fluid device 100 according to the embodiment of the present invention includes two flow paths 200 along the outer periphery of the inflow port 122. The channel 200 is defined by a wall 230 including a plurality of ribs 210 and has two openings. As shown in FIG. 12, in this example, two channels 200 are provided approximately symmetrically in the left and right when viewed in cross section.
隣接するリブ２１０の間の壁部２３０は、図１２に示す断面でみたときに直線で構成してもよく、曲線で構成してもよい。隣接するリブ２１０の間の壁部２３０が直線で構成されても、曲線で構成されても、リブ２１０の存在により、流路２００は複数の角を有するように構成される。それにより、流路２００は細かく折れ曲がった気流を発生させる。 The wall part 230 between the adjacent ribs 210 may be constituted by a straight line or a curved line when viewed in the cross section shown in FIG. Regardless of whether the wall 230 between the adjacent ribs 210 is a straight line or a curved line, the flow path 200 is configured to have a plurality of corners due to the presence of the rib 210. As a result, the flow path 200 generates a finely bent airflow.
リブ２１０は、この例では、図１２に示すように、流入口側の断面でみたときに流路２００を規定する左側の壁部及び流路を規定する右側の壁部に交互に７個形成されている。リブ２１０の数や配置はこれに限られず、気流吐出ユニット１２０や流路２００の大きさに対応させて決定するとよい。具体的には、リブ２１０の数は、流路２００内の流体の抵抗が大きくなりすぎないように配慮しつつ、可能な限り流路２００の流路長が長くなるように決定するとよい。また、リブ２１０の配置は左右交互でなくてもよい。 In this example, as shown in FIG. 12, seven ribs 210 are alternately formed on the left wall defining the flow path 200 and the right wall defining the flow path when viewed in cross section on the inlet side. Has been. The number and arrangement of the ribs 210 are not limited to this, and may be determined according to the size of the airflow discharge unit 120 and the flow path 200. Specifically, the number of ribs 210 may be determined so that the flow path length of the flow path 200 is as long as possible while considering that the resistance of the fluid in the flow path 200 does not become too large. Further, the arrangement of the ribs 210 may not be left and right alternately.
また、リブ２１０は、流入口の断面でみたときに流路の幅Ｗの２分の１より大きい凸状を有するように形成される。このような大きさに形成することで、流路２００を通る流体が気流吐出ユニット１２０の外周の曲線に沿った流れになることを防ぎ、より確実に流路長を長くすることができる。 Further, the rib 210 is formed so as to have a convex shape larger than a half of the width W of the flow path when viewed in a cross section of the inflow port. By forming in such a size, it is possible to prevent the fluid passing through the flow path 200 from flowing along the curve on the outer periphery of the airflow discharge unit 120, and to increase the flow path length more reliably.
流路２００は、気流吐出ユニット１２０と一体的に形成してもよいし、気流吐出ユニット１２０とは別に製造したうえで、気流吐出ユニット１２０に装着させてもよい。 The flow path 200 may be formed integrally with the airflow discharge unit 120 or may be manufactured separately from the airflow discharge unit 120 and then attached to the airflow discharge unit 120.
＜気流吐出ユニット１２０を取り付けた流体機器１００の作用＞
流入口１２２から気流吐出ユニット１２０に流入した気流は、コアンダ効果により、流出口１２４の上部１４０又は下部１４２のいずれか一方に沿って進む。コアンダ効果とは、気体や液体の噴流のそばに湾曲した壁があると、噴流はその壁の曲面に沿った方向を流れようとする現象をいう。
<Operation of fluidic device 100 with airflow discharge unit 120 attached>
The airflow that has flowed into the airflow discharge unit 120 from the inflow port 122 travels along either the upper portion 140 or the lower portion 142 of the outflow port 124 due to the Coanda effect. The Coanda effect is a phenomenon in which when a curved wall is present near a gas or liquid jet, the jet tends to flow in a direction along the curved surface of the wall.
例えば上部１４０に沿って気流が進んでいるとき、開口部Ｐ２及び開口部Ｐ４付近の圧力は、開口部Ｐ１及び開口部Ｐ３付近の圧力に比べて低圧となる。気体は圧力が高い方から低い方へ流れるため、左側の流路２００では、開口部Ｐ１から開口部Ｐ２の方向へ、また、右側の流路２００では、開口部Ｐ３から開口部Ｐ４の方向へ気流が生じる。 For example, when the airflow advances along the upper part 140, the pressure near the opening P2 and the opening P4 is lower than the pressure near the opening P1 and the opening P3. Since the gas flows from a higher pressure to a lower pressure, in the left channel 200, the gas flows from the opening P1 to the opening P2, and in the right channel 200, the gas flows from the opening P3 to the opening P4. Airflow is generated.
これが継続して、開口部Ｐ２及び開口部Ｐ４付近の圧力と、開口部Ｐ１及び開口部Ｐ３付近の圧力とが逆転し、開口部Ｐ２及び開口部Ｐ４付近の圧力が、開口部Ｐ１及び開口部Ｐ３付近の圧力に比べて高圧となると、上部１４０に沿って進んでいた気流は下部１４２に沿って進むようになる。 This continues, and the pressure near the opening P2 and the opening P4 and the pressure near the opening P1 and the opening P3 are reversed, and the pressure near the opening P2 and the opening P4 becomes the opening P1 and the opening. When the pressure is higher than the pressure in the vicinity of P3, the airflow that has traveled along the upper portion 140 travels along the lower portion 142.
下部１４２に沿って気流が進むようになると、開口部Ｐ１及び開口部Ｐ３付近の圧力は、開口部Ｐ２及び開口部Ｐ４付近の圧力に比べて低圧となる。気体は圧力が高い方から低い方へ流れるため、左側の流路２００では開口部Ｐ２から開口部Ｐ１の方向へ、また、右側の流路２００では開口部Ｐ４から開口部Ｐ３の方向へ気流が生じる。 When the air flow proceeds along the lower portion 142, the pressure in the vicinity of the opening P1 and the opening P3 becomes lower than the pressure in the vicinity of the opening P2 and the opening P4. Since the gas flows from a higher pressure to a lower pressure, the air flow is from the opening P2 to the opening P1 in the left channel 200, and from the opening P4 to the opening P3 in the right channel 200. Arise.
これが継続して、開口部Ｐ２及び開口部Ｐ４付近の圧力と、開口部Ｐ１及び開口部Ｐ３付近の圧力とが逆転し、開口部Ｐ１及び開口部Ｐ３付近の圧力が、開口部Ｐ２及び開口部Ｐ４付近の圧力に比べて高圧となると、下部１４２に沿って進んでいた気流は再び上部１４０に沿って進むようになる。 This continues, and the pressure near the opening P2 and the opening P4 and the pressure near the opening P1 and the opening P3 are reversed, and the pressure near the opening P1 and the opening P3 becomes the opening P2 and the opening. When the pressure is higher than the pressure in the vicinity of P4, the airflow that has traveled along the lower portion 142 again travels along the upper portion 140.
この動作が繰り返されることで、上部１４０に沿った気流Ｘ及び下部１４２に沿った気流Ｙが継続的に一定の速度で交互に切り替わり、気流吐出ユニット１２０を通過する気流が上部１４０の方向及び下部１４２の方向にゆっくりと揺らされる。 By repeating this operation, the airflow X along the upper portion 140 and the airflow Y along the lower portion 142 are continuously switched alternately at a constant speed, and the airflow passing through the airflow discharge unit 120 moves in the direction of the upper portion 140 and the lower portion. Sway slowly in the direction of 142.
本発明の一実施形態に係る流体機器１００の気流吐出ユニット１２０の流路２００は、流路２００を規定する壁部２３０に複数のリブ２１０が存在することにより、細かく折れ曲げられている。よって、小型化された気流吐出ユニットにおいても流路長を長くすることができる。流路２００の流路長が長くなると、上述した圧力の切り替わりによる気流の方向の切り替わりがゆっくりと行われるようになる。したがって、気流吐出ユニット１２０を横断する気流が上部１４０の方向及び下部１４２の方向にゆっくりと揺らされ、揺らしの効果を高めることができる。 The flow path 200 of the airflow discharge unit 120 of the fluid device 100 according to the embodiment of the present invention is finely bent due to the presence of the plurality of ribs 210 on the wall 230 that defines the flow path 200. Therefore, the flow path length can be increased even in a downsized airflow discharge unit. As the flow path length of the flow path 200 increases, the direction of the airflow is switched slowly due to the pressure change described above. Therefore, the airflow crossing the airflow discharge unit 120 is slowly shaken in the direction of the upper part 140 and the direction of the lower part 142, and the effect of the shaking can be enhanced.
ところで、気流の向きを瞬時にはっきり切り替えることに主眼が置かれている従来技術を用いると、流路が曲線で形成されるため、気流が強化され、気流の切り替えが速くなってしまう。このため、使用者は、体感的に風が広がっているだけに感じてしまう。 By the way, when the conventional technique which focuses on instantly switching the direction of the airflow is used, the flow path is formed in a curved line, so that the airflow is strengthened and the airflow is quickly switched. For this reason, the user feels that the wind is experientially spreading.
しかしながら、本発明の一実施形態に係る流体機器１００の気流吐出ユニット１２０は、上述の構造を備える流路２００を有しているため、気流がゆっくりと揺らされる。したがって、上記従来技術を用いる場合に比して、気流がゆっくり揺らされることにより、使用者は体感的に風の「揺らぎ」を感じ易くなる。 However, since the airflow discharge unit 120 of the fluid device 100 according to the embodiment of the present invention includes the flow path 200 having the above-described structure, the airflow is slowly shaken. Therefore, as compared with the case where the above-described conventional technique is used, the airflow is slowly shaken, so that the user can easily feel the “fluctuation” of the wind.
このように、本発明の一実施形態に係る流体機器１００の気流吐出ユニット１２０を用いると、気流吐出ユニット１２０を横断する気流が上部１４０の方向及び下部１４２の方向にゆっくりと揺らされるので、気流の強さが均一で広がった風を得ることができ、流体機器からの風の「揺らし」効果を得ることができる。 As described above, when the airflow discharge unit 120 of the fluid device 100 according to the embodiment of the present invention is used, the airflow crossing the airflow discharge unit 120 is slowly shaken in the direction of the upper part 140 and the direction of the lower part 142. Therefore, it is possible to obtain a wind with a uniform intensity and a “swaying” effect of the wind from the fluid device.

(Second Embodiment)
FIG. 13 is a cross-sectional perspective view showing the configuration of the inlet side of the airflow discharge unit of the fluid device according to the second embodiment of the present invention. FIG. 14 is a cross-sectional view of the airflow discharge unit of the fluid device according to the second embodiment of the present invention on the inlet side.
本発明の第二の実施形態に係る流体機器５００の気流吐出ユニット５２０は、流体機器１００の気流吐出ユニット１２０と、流路の形状、特に壁部の形状及び配置の仕方において異なる。 The airflow discharge unit 520 of the fluid device 500 according to the second embodiment of the present invention is different from the airflow discharge unit 120 of the fluid device 100 in the shape of the flow path, particularly the shape and arrangement of the wall portion.
本発明の第二の実施形態に係る流体機器の気流吐出ユニット５２０は流路６００を備える。流路６００は、気流吐出ユニット５２０の外壁６０５及び壁部６３０により規定される。流路６００は、壁部６３０のみにより規定されてもよい。図１２に示すように、流路２００は、この例では、断面でみたときに左右に２本、略対称に備えられる。 An airflow discharge unit 520 of a fluid device according to the second embodiment of the present invention includes a flow path 600. The flow path 600 is defined by the outer wall 605 and the wall portion 630 of the airflow discharge unit 520. The flow path 600 may be defined only by the wall portion 630. As shown in FIG. 12, in this example, two channels 200 are provided approximately symmetrically in the left and right when viewed in cross section.
流路６００は、この例では２回折り曲げられた形状に形成されている。具体的には、流路６００は、まず、開口部Ｐ１及び開口部Ｐ５から気流吐出ユニット５２０の外周に沿って形成され、折り曲げ部Ｐ２及び折り曲げ部Ｐ６で折り曲げられて略１８０度方向が転換され、さらに、折り曲げ部Ｐ３及び折り曲げ部Ｐ７で折り曲げられて略１８０度方向が転換され、開口部Ｐ４及び開口部Ｐ８まで形成される。流路６００を折り曲げる回数はこれに限られず、気流吐出ユニット５２０や流路６００の大きさに対応させて決定するとよい。具体的には、流路６００を折り曲げる回数は、流路６００内の流体の抵抗が大きくなりすぎないように配慮しつつ、可能な限り流路６００の流路長が長くなるように決定するとよい。また、折り曲げ部で方向が転換される角度は１８０度でなくてもよく、気流吐出ユニット５２０の大きさや形状に応じて決定されればよい In this example, the channel 600 is formed in a shape bent twice. Specifically, the flow path 600 is first formed from the opening P1 and the opening P5 along the outer periphery of the airflow discharge unit 520, and is bent by the bent portion P2 and the bent portion P6 to change the direction by about 180 degrees. Furthermore, it is bent at the bent portion P3 and the bent portion P7, the direction is changed by about 180 degrees, and the opening portion P4 and the opening portion P8 are formed. The number of times the flow path 600 is bent is not limited to this, and may be determined according to the size of the airflow discharge unit 520 or the flow path 600. Specifically, the number of times the flow path 600 is bent may be determined so that the flow path length of the flow path 600 is as long as possible while considering that the resistance of the fluid in the flow path 600 does not become too large. . Further, the angle at which the direction is changed at the bent portion may not be 180 degrees, and may be determined according to the size and shape of the airflow discharge unit 520.
壁部６３０は、図１４に示す断面でみたときに直線で構成してもよく、曲線で構成してもよい。壁部６３０が直線で構成されても、曲線で構成されても、折り曲げ部Ｐ２、Ｐ３、Ｐ６、Ｐ７の存在により、流路６００は複数の角を有するように構成される。それにより、流路６００は大きく折れ曲がった気流を発生させる。 The wall 630 may be configured with a straight line or a curved line when viewed in the cross section shown in FIG. Regardless of whether the wall portion 630 is configured by a straight line or a curved line, the flow path 600 is configured to have a plurality of corners due to the presence of the bent portions P2, P3, P6, and P7. Thereby, the flow path 600 generates a largely bent airflow.
流路６００は、気流吐出ユニット５２０と一体的に形成してもよいし、気流吐出ユニット５２０とは別に製造したうえで、気流吐出ユニット５２０に装着させてもよい。 The flow path 600 may be formed integrally with the airflow discharge unit 520 or may be manufactured separately from the airflow discharge unit 520 and then attached to the airflow discharge unit 520.
＜気流吐出ユニット５２０を取り付けた流体機器の作用＞
流入口１２２から気流吐出ユニット５２０に流入した気流は、コアンダ効果により、流出口１２４の上部１４０又は下部１４２のいずれか一方に沿って進む。例えば流出口１２４の上部１４０に沿って気流が進んでいるとき、開口部Ｐ４及び開口部Ｐ８付近の圧力は、開口部Ｐ１及び開口部Ｐ５付近の圧力に比べて低圧となる。気体は圧力が高い方から低い方へ流れるため、左側の流路６００では開口部Ｐ１から開口部Ｐ４の方向へ、また、右側の流路６００では開口部Ｐ５から開口部Ｐ８の方向へ気流が生じる。
<Operation of Fluid Device with Airflow Discharge Unit 520>
The airflow that flows into the airflow discharge unit 520 from the inflow port 122 travels along either the upper portion 140 or the lower portion 142 of the outflow port 124 due to the Coanda effect. For example, when the airflow is traveling along the upper part 140 of the outlet 124, the pressure near the opening P4 and the opening P8 is lower than the pressure near the opening P1 and the opening P5. Since the gas flows from the higher pressure side to the lower pressure side, the airflow flows from the opening P1 to the opening P4 in the left channel 600, and from the opening P5 to the opening P8 in the right channel 600. Arise.
これが継続して、開口部Ｐ４及び開口部Ｐ８付近の圧力と、開口部Ｐ１及び開口部Ｐ５付近の圧力とが逆転し、開口部Ｐ４及び開口部Ｐ８付近の圧力が、開口部Ｐ１及び開口部Ｐ５付近の圧力に比べて高圧となると、上部１４０に沿って進んでいた気流は下部１４２に沿って進むようになる。 This continues, and the pressure near the opening P4 and the opening P8 and the pressure near the opening P1 and the opening P5 are reversed, and the pressure near the opening P4 and the opening P8 becomes the opening P1 and the opening. When the pressure is higher than the pressure in the vicinity of P5, the airflow that has traveled along the upper portion 140 travels along the lower portion 142.
下部１４２に沿って気流が進むようになると、開口部Ｐ１及び開口部Ｐ５付近の圧力は、開口部Ｐ４及び開口部Ｐ８付近の圧力に比べて低圧となる。気体は圧力が高い方から低い方へ流れるため、左側の流路６００では開口部Ｐ４から開口部Ｐ１の方向へ、また、右側の流路６００では開口部Ｐ８から開口部Ｐ５の方向へ気流が生じる。 When the air flow proceeds along the lower part 142, the pressure near the opening P1 and the opening P5 becomes lower than the pressure near the opening P4 and the opening P8. Since the gas flows from a higher pressure to a lower pressure, an air flow is generated from the opening P4 to the opening P1 in the left channel 600, and from the opening P8 to the opening P5 in the right channel 600. Arise.
これが継続して、開口部Ｐ４及び開口部Ｐ８付近の圧力と、開口部Ｐ１及び開口部Ｐ５付近の圧力とが逆転し、開口部Ｐ１及び開口部Ｐ５付近の圧力が、開口部Ｐ４及び開口部Ｐ８付近の圧力に比べて高圧となると、下部１４２に沿って進んでいた気流は再び上部１４０に沿って進むようになる。 This continues, and the pressure near the opening P4 and the opening P8 and the pressure near the opening P1 and the opening P5 are reversed, and the pressure near the opening P1 and the opening P5 becomes the opening P4 and the opening. When the pressure becomes higher than the pressure in the vicinity of P8, the airflow that has traveled along the lower portion 142 again travels along the upper portion 140.
この動作が繰り返されることで、上部１４０に沿った気流Ｘ及び下部１４２に沿った気流Ｙが継続的に一定の速度で交互に切り替わり、気流吐出ユニット５２０を通過する気流が上部１４０の方向及び下部１４２の方向にゆっくりと揺らされる。 By repeating this operation, the airflow X along the upper portion 140 and the airflow Y along the lower portion 142 are continuously switched alternately at a constant speed, and the airflow passing through the airflow discharge unit 520 moves in the direction of the upper portion 140 and the lower portion. Sway slowly in the direction of 142.
本発明の一実施形態に係る流体機器の気流吐出ユニット５２０の流路６００は、大きく気流の方向を変える折り曲げ部を複数備え、複数回折り曲げられた形状に形成されていることにより、小型化された気流吐出ユニットにおいても流路長を長くすることができる。流路６００の流路長が長くなると、上述した圧力の切り替わりによる気流の方向の切り替わりがゆっくりと行われるようになる。したがって、気流吐出ユニット５２０を横断する気流が上部１４０の方向及び下部１４２の方向にゆっくりと揺らされ、揺らしの効果を得ることができる。 The flow path 600 of the airflow discharge unit 520 of the fluid device according to the embodiment of the present invention includes a plurality of bent portions that greatly change the direction of the airflow, and is formed into a bent shape. Even in the air flow discharge unit, the flow path length can be increased. As the flow path length of the flow path 600 becomes longer, the change of the direction of the airflow due to the pressure change described above is performed slowly. Therefore, the airflow crossing the airflow discharge unit 520 is slowly shaken in the direction of the upper part 140 and the direction of the lower part 142, and the effect of shaking can be obtained.
上述の実施形態に係る流体機器１００の気流吐出ユニット１２０、５２０は、以下の特徴を有する。 The airflow discharge units 120 and 520 of the fluid device 100 according to the above-described embodiment have the following characteristics.

A second flow path 200 (600) that is provided outside the flow path, has two openings, and communicates with the first flow path through the two openings. The distance L 1 between the two openings of the flow path 200 (600) is a line parallel to the peripheral wall forming the first flow path and the length L of the imaginary line connecting the two openings. Longer than 2 .
