が良い。BACKGROUND OF THE INVENTION In recent years, air conditioning equipment has come to serve both as a cooling and heating device, and it has become desirable to be able to freely control the temperature distribution in a room according to the user's needs from the standpoint of both comfort and economy. Generally, for comfort, it is better to uniformize the temperature distribution in the air-conditioned room by blowing hot air downwards during heating and dispersing cold air in one direction during cooling.

、集中送風もできることが望ましい。In addition, as with zone heating and cooling, which has recently been requested by customers, air conditioning equipment can be used to spot air condition only a part of the space where people live, taking economic efficiency into consideration. It is desirable to be able to deflect the airflow over a wide range without being restricted by the installation location, and also be able to perform concentrated air blowing.
このような目的を達成するために、偏向板を用いた送風
制御根面が用いられてきた。To achieve this objective, air control root planes using deflection plates have been used.
以下図面を参照しながら、丘述した従来の流れ方向制御
装置の一例について説明する。An example of the conventional flow direction control device described above will be described below with reference to the drawings.

。In FIGS. 6 and 7, 1 is a guide wall, 2 is a nozzle that blows out cold and hot air, and 3 is a deflection plate rotated by a shaft 4.
以とのように構成された従来の流れ方向制御装置につい
て、以下その動作について説明する。The operation of the conventional flow direction control device configured as described above will be explained below.

、ノズ）ｖ２から出た流れは案内壁１に付着し偏向され
る。偏向板３を回転すると流れが付着する案内壁１が回
転し、吹出し風向が変化する。First, the flow sent from the blower (not shown) passes through the pipe channel (not shown) and is deflected by the deflection plate 3 of the flow direction control device installed at the end of the channel. The flow coming out of the nozzle v2 adheres to the guide wall 1 and is deflected. When the deflection plate 3 is rotated, the guide wall 1 to which the flow adheres rotates, and the direction of the blowing air changes.
発明が解決しようとする問題点
しかしながら上記のような構成では、流路中で最も流路
断面蹟が狭くなるノズル２の入口部分の位置に偏向板３

ろうとして偏向板４の角度を増加させると、通風抵抗が
増大すると同時に偏向板３の下流に大きな乱流渦域が発
生し、乱流騒音の発生原因となっていた。Problems to be Solved by the Invention However, in the above configuration, the deflection plate 3 is placed at the inlet portion of the nozzle 2 where the cross-sectional area of the flow path is the narrowest.
The problem is that this creates a high ventilation resistance and that a large deflection angle cannot be obtained because the deflection occurs at a position where the wind velocity is high. Moreover, when the angle of the deflection plate 4 is increased in an attempt to increase the deflection angle, ventilation resistance increases and, at the same time, a large turbulent vortex region is generated downstream of the deflection plate 3, causing turbulence noise. .

構成を備えたものである。Means for Solving the Problems In order to solve the above-mentioned problems, the flow direction control device of the present invention is provided at the outlet end of a channel in a pipe, and disperses the flow from the central axis of the channel toward the outer wall of the channel. and a guide wall that is provided near the downstream side of the flow divider, has an outlet smaller than the outer diameter of the flow divider, and has a shape that gradually expands downstream from the outlet. an enlarged nozzle provided between the enlarged nozzle and the bottom surface of the flow divider, supporting the flow divider, and built inside the expansion nozzle so that the flow divider can be freely configured by being independently housed or extended; It is equipped with a control rod that can be freely tilted at any angle in the direction of.

に任意の角度だけ傾き、流れの方向が制御される。Effect of the Invention With the above-described configuration, the present invention has the flow flowing out to the outlet end of the pipe internal flow path to be diverted around the pipe internal flow path by the flow divider, and immediately after that, the flow is sandwiched between the bottom surface of the flow divider and the upstream end surface of the enlarged nozzle. It is again directed toward the center by the flow path and discharged to the outside world through the enlarged nozzle outlet. At this time, the turbulence of the flow from upstream is rectified by the flow divider, and the flow direction is controlled by tilting the flow divider by an arbitrary angle in an arbitrary direction by expanding and contracting the control rod.

心方向へ向かうバイアス流れが生成され、中心部分に集
められた流れはバイアス流れの全圧がつｔあっているた
めに拡大ノカレ吹出口より鉛直方向に放出される。That is, when the flow divider is located at the center, a bias flow toward the center is generated by the flow path formed by the bottom surface of the flow divider and the upstream end surface of the enlarged nozzle, and the flow collected in the center portion is the bias flow. Since the total pressure is equal, it is discharged vertically from the enlarged nokare outlet.

付着現象を引き起こして、傾いた分流器の方向へ大きく
偏向される。However, when the flow divider is tilted by the control rod, the flow path consisting of the flow divider in the tilted direction and the upstream end face of the enlarged nozzle is pinched, and a portion of the bias flow flowing through that area is blocked, resulting in a reduction in the flow at the outlet. As a result, the total pressure distribution in the circumferential direction becomes unbalanced.As a result, the bias flow from the surroundings acts on the large nozzle outlet by the total pressure difference near the outlet of the enlarged nozzle guide wall near the area blocked by the flow path. The flow blown out from the nozzle causes a flow adhesion phenomenon due to the Coanda effect on the enlarged nozzle guide wall, and is largely deflected toward the inclined flow divider.

の結果、吹出し流れは分流器の偏向角度および翼の偏向

を制御することが可能となる。Furthermore, by changing the angle of the flow divider, the gap in the flow path changes, and the strength of the flow adhesion to the guide wall changes. As a result, the blowing direction of the blowing flow can be controlled three-dimensionally in all directions according to the deflection angle of the flow divider and the deflection position of the blade.

傾斜できるように固定される。In FIG. 81, reference numeral 5 denotes a blowing lower which is provided at the end of an outer wall 6 of the flow path for guiding the flow sent from a blower (not shown), and has an inner diameter smaller than the outer diameter of the outer wall 6 of the flow path; This is an expanding nozzle configured with a guide wall 8 that gradually expands downstream from the air outlet 7. A flow divider 9 is provided on the upstream side of the enlarged nozzle/I15 to disperse the flow in the outer wall 6 of the flow path outward with respect to the central axis of the flow path, and the flow divider 9 is arranged between the upstream end face 10 of the enlarged nozzle 5 and the flow splitter 9. The bias flow flowing toward the center is gathered again by the action of the flow channel constriction formed by the bottom surface 11 of the container 9, and the flow is rectified. Furthermore, control rods 12 are embedded in the flow divider 9 and can be expanded and contracted independently.
2, the flow divider 9 can be tilted in any direction and at any angle by interlocking with the enlarged nozzle/l'h flow end surface 1o or by independently driving and controlling the change in expansion/contraction length. Fixed.
以上のようＫ１１ｌ成された流れ方向制御装置について
、以下第２図から第５図を用いてその動作を説明する。The operation of the flow direction control device constructed as above will be described below with reference to FIGS. 2 to 5.

1 is an enlarged nozzle) vJ: The case where the nozzle is in contact with the flow end surface 10 on the right side of the figure will be explained. In this case, the flow Fl entering the flow path becomes a flow F directed outward due to the action of the flow divider 9.

できる。becomes. As a result, the flow collides with the outer wall 6 of the flow path, becomes a flow along the upstream end face 10 of the enlarged nozzle and the bottom face 11 of the flow divider, and becomes a bias flow FB directed toward the axis of the flow path due to the action of the throttle. Here, a bias flow also occurs on the right side of the figure, but due to the inclination of the flow divider 9, the enlarged nozzle /'
The bias flow FB is blocked by the shielding effect due to contact with the h-flow end face 10. Therefore, the flow FA coming out of the blowout lower of the enlarged nozzle 5 is pushed by the bias flow FB from the left side of the figure and directed toward the guide wall 8 on the right side. As a result, the flow FA coming out of the enlarged nozzle 5 interferes with the guide wall 8, flows along the surface of the guide wall 8 due to the Coanda effect, and is deflected over a wide angle without substantially reducing the air volume. In this case, the maximum deflection angle can be arbitrarily set depending on the shape of the guide wall 8.
次に第３図に示すように、分流器９の左側部分を傾け、
その先端を接触させた場合について説明する。この場合
、図中の左側のバイアス流れＦＢが遮られ、拡大ノズ）
Ｖ５の吹出ロアから出る流れＦＡは左側に傾き、左側の
案内壁８に沿って広角に左側に偏向する。Next, as shown in FIG. 3, tilt the left side of the flow divider 9,
A case where the tips thereof are brought into contact will be explained. In this case, the bias flow FB on the left side of the figure is blocked and the enlarged nozzle)
The flow FA coming out of the blowout lower of V5 is inclined to the left and is deflected at a wide angle to the left along the left guide wall 8.
すなわち、分流器９の傾きによる遮蔽位置に応じて、遮
蔽位置の存在する方向に流れは広角に偏向することにな
る。That is, depending on the shielding position due to the inclination of the flow divider 9, the flow is deflected over a wide angle in the direction of the shielding position.
また、流れＦ。よりも上流の流れについては全て第２図
と同一であるため、以下は省略する。Also, flow F. The flow upstream from this point is all the same as in FIG. 2, so the following description will be omitted.
次に第４図に示すように、分流器９をαだけ傾け、分流
器先端をわずかな間隙を設けた場合について説明する。Next, as shown in FIG. 4, a case where the flow divider 9 is tilted by α and a slight gap is provided between the ends of the flow divider will be described.
この場合、このわずかな間隙を通過する流れＦＢＬが発
生し、この作用により拡大ノズル５の、を
吹出ロアから出る流れＦＡの傾き力が小なくなる。In this case, a flow FBL passing through this small gap is generated, and as a result of this action, the inclination force of the flow FA exiting from the blowing lower of the enlarged nozzle 5 is reduced.
この結果、案内壁８への付着の度合も減少し、偏向角度
も第３図に比較して小さくなる。そして、この間隙を序
々に大きくしていくように傾き角度αを小さくしていく
と、流れの偏向角変はしだいに小さくなり、最終的には
第５図に示すように偏向角度はついに零となる。As a result, the degree of adhesion to the guide wall 8 is also reduced, and the deflection angle is also smaller compared to FIG. 3. If the inclination angle α is decreased by gradually increasing this gap, the change in the deflection angle of the flow will gradually become smaller, and eventually the deflection angle will finally reach zero as shown in Figure 5. becomes.
即ち、分流器９の傾斜角度αを変化させることによって
、流れの偏向角度を任意に設定することができる。That is, by changing the inclination angle α of the flow divider 9, the deflection angle of the flow can be arbitrarily set.

a flow divider that disperses the flow from the central axis of the flow path toward the outer wall of the flow path; and a flow outlet provided near the downstream side of the flow divider and having a smaller outer diameter than the flow divider; an expanding nozzle configured with a guide wall that gradually expands toward the downstream side; and an expanding nozzle that is provided between the expanding nozzle and the bottom surface of the flow divider, supports the flow divider, and is built inside the expansion nozzle. By providing a control rod that can be independently retracted or extended to freely tilt the flow divider in any direction and at any angle, the flow can be converged and freely deflected in any direction and at any angle. It is something that makes you burst out into laughter. Furthermore, since there is no flat plate or the like on the upstream side of the blowout flow that disturbs the flow, the blowout flow exiting the enlarged nozzle shows good adhesion to the guide wall due to the Coanda effect, and deflection can be obtained over a wide angle and over a wide range. Moreover, due to the action of the flow divider's throttle, the flow passing through the center of the flow path becomes a bias flow, which ensures reliable adhesion to the guide wall, improving deflection characteristics and reducing turbulent flow noise. can also decrease.
