Abstract

PURPOSE:To remarkably deflect flow by means of a simple constitution along with the dividing operation of the flow by moving a bias projection approximately in parallel with the flow direction in association with the turning motion of a flow control member. CONSTITUTION:When a cam 81 is turned, a transmitting bar 82 is swung to slide a bias projection 80 via a connecting projection 84. With the bias projection 80 staying on the upstream side of flow, a linear wall 9 is more perfectly exposed to the upstream flow Fa, giving horizontal blow. When the bias projection 80 is slided downstream, the area of the flow dividing part 10c of a flow control member which is exposed to the upstream Fa is large to enhance combination of the flows Fa and Fb on the downstream side, giving downward blow. Additionally, when the flow control member is turned furthermore, the bias projection 80 is slided upstream again. Since the area of the linear wall 9 which is exposed to the upstream flow Fa begins to be enlarged, the flow is divided more perfectly.

しまい、十分な空調効果を得ることができなかった。Originally, in a heat pump, in order to equalize the temperature distribution in the room to be air-conditioned, it is desirable to control the direction of the airflow to downward blowing during heating and horizontal blowing during cooling. However, as shown by the broken line in Figure 1, when the air is deflected downward, the louver almost blocks the air outlet, resulting in a significant drop in air volume and making it impossible to obtain a sufficient air conditioning effect. There wasn't.

るものである。Furthermore, if a large amount of hot air is blown downward during heating, the amount of hot air may be too large and may cause discomfort when it hits the human body. If the purpose is to keep the temperature distribution constant,
Experiments have confirmed that a nearly constant temperature distribution can be obtained by blowing a certain amount of air downward and the rest horizontally. Therefore, in order to improve the temperature distribution and eliminate the discomfort caused by the hot air being blown out, it is necessary to have a function to blow out a certain amount of hot air downwardly and the rest to be blown horizontally, that is, to have a function of dividing the flow. In the conventional air blowing device, it was impossible to provide the function of dividing the flow as described above.Objective of the InventionThe present invention is intended to eliminate such conventional drawbacks, and to provide the function of dividing the air flow as described above without substantially changing the volume of air blown. This significantly deflects the flow and enables diversion, improving comfort during air conditioning.

A flow control member is provided substantially parallel to the plane wall and substantially perpendicular to the flow, and the flow control member rotates around a rotation axis, and has a substantially circular arc shape with a center O eccentric from the rotation axis. One side of the extension of the head is a bias acting part, and the other is a substantially arc-shaped shunting part, and a part of the flow is directed to the curved surface. A bias protrusion is provided to deflect the bias toward the wall, and a straight wall is provided downstream of the bias protrusion, and the bias protrusion is configured to move substantially parallel to the direction of flow in response to rotation of the flow control member. This is what I did.

In addition, by rotating the flow control member, it is possible to perform a diversion operation in which the flow is divided into two directions, horizontally and downwardly.

It has a substantially arc-shaped head 10a that is more eccentric than the il+ 11, and one side on the extension line of the head consists of a bias acting part 10b and the other part a substantially arc-shaped flow dividing part 10c. It is columnar.

によって曲面壁７に伺着し、下方に向かって流れ出る。First, the case where the flow control member 10 is rotated to the position shown in FIG. 3 will be described. In this case, the flow sent out from the air source 4 and reaching the position of the flow control member 1o is
It is divided into an upper flow Fa and a lower flow Fb by a. Part of the upper flow Fa flows through the bias protrusion 80.
As a result of being bent downward in the figure due to the action, it flows along the flow dividing portion 10C of the flow control member 1o. Since the flow dividing portion 10c faces slightly upward as shown in the figure, Fa flows along the straight wall 9 provided on the downstream side of the bias protrusion 8, and is blown out in the horizontal direction. The flow Fb is the bias acting part 1o
Since b is facing almost horizontally, it blows out in the horizontal direction. Therefore, the entire flow of the 7th page blows out almost in the water direction as shown in the figure. Next, the case where the flow control member 1o is rotated to the position shown in FIG. 4 will be described. In this case, the upper flow Fa flows along the flow dividing portion 10c under the influence of the bias protrusion 8, as in the case described above. At this time, as shown in the figure, the flow dividing portion 10c faces slightly downward, so Fa
It blows out in a hazy manner, pointing downwards. -The flow Fb on the inferior side is
Since the bias acting portion 10b faces downward, this action causes the liquid to arrive at the curved wall 7 and flow downward.

合流した流ｉｔは図のように下方に向かって流れ出る。As a result, the flow it which is the confluence of the flow hFa on the upper side (Ill) and the flow Fb on the lower side flows downward as shown in the figure.

In this case, part of the upper flow Fa is deflected to the lower side of the diagram due to the influence of the bias protrusion 8, but since the flow control member 10b is oriented in the − direction, the flow Fa is deflected toward the straight wall. It blows out almost horizontally along line 9. - The flow Fb on the inferior side adheres to the curved wall 7 due to the action on the opposite side of the diversion action section 10C and blows out downward. In this case, since the two flows Fa and Fb flow along the straight wall 9 and the curved wall 7, respectively, they flow out in separate directions, horizontally and downward, without merging with each other, resulting in a branching operation.

いないことがわかる。As described above, by rotating the flow control member 1o, it is possible to deflect the flow downward from the horizontal over a wide angle, and also to separate the flow horizontally and downward and blow it out. At this point, the flow control is not by forcibly bending the flow, but by deflecting it by using the effect of the flow adhering to the flow control member 1o, the curved wall 7, etc., so the air volume is almost reduced. There's nothing to do. Experimental data for an example of this flow direction control device are shown in FIGS. 7 and 8. FIG. 7 shows the flow deflection angle a (θ and a
(shown in FIG. 4), and FIG. 8 shows the relationship between the rotation angle θ of the flow control member 10 and the air volume reduction rate. As the angle θ increases in FIG. 7, the deflection angle α also increases proportionally, and θ becomes approximately 60
When it is 0, a reaches about 800. In addition, it is divided into 9 pages for setting θ to 100° or more, and 19 pages for flow J'Lir upper and lower component water,
A state of diversion occurs. FIG. 8 shows the rate of decrease in air volume at this time, and it can be seen that even if the angle of 0 is rotated, it changes by only about 10%.

よって常にカム８１に接触する状態に保たれている。As shown in FIGS. 9 to 12, in the embodiment of the present invention, the bias protrusion 8o is configured to move in a direction substantially parallel to the flow in response to rotation of the flow control member 10. The bias protrusion 80 is configured to slide between the plane wall 6 and the guide plate 90, and is configured to move in conjunction with the flow control member 1o by a mechanism shown in FIG. A cam 8 is attached to the extended end of the rotating shaft 11 of the flow control member 10.
1 is provided, and the cam 81 rotates in the same manner as the flow control member 10. When this cam 81 rotates, the transmission rod 82
It swings around the transmission dl+s ts and moves the bias protrusion 80 via a coupling protrusion 84 provided on the bias protrusion 80. The transmission rod 82 is always kept in contact with the cam 81 by a return spring 83.

が可能となる。With the above configuration, the operations shown in FIGS. 9 to 11 are performed. FIG. 9 shows the case of horizontal blowing, in which the bias protrusion 80 has moved to the upstream side of the flow and is in a position where the length of the straight wall 9 is increased. When a flow is generated in this state, the upper flow Fa adheres more completely to the straight wall 9, and the velocity distribution in horizontal blowing becomes more uniform. Next, as shown in FIG. 10, when the flow control member is tilted to the downward blowing position, the transmission rod 82 is moved to the position indicated by the dashed line by the action of the cam 81, and the bias protrusion 80 is moved downstream. When a flow is generated in this state, the upper flow Fa has a greater effect of adhering to the flow dividing portion 10C of the flow control member, so that the merging of Fa and Fb downstream of the flow control member 10 becomes easier.
As the deflection angle in downward blowing increases, the velocity distribution becomes more uniform. Next, as shown in Figure 11, flow 11
When the control member is rotated from the downward blowing position to the diversion operation position, the bias protrusion 80 moves to the upstream side again, and the adhesion effect of the flow Fa on the − side to the straight wall 9 is reduced. This allows for a more complete flow diversion. That is, the bias protrusion 80 is rotated according to the rotation of the flow control member 10.
By moving the position of the bias protrusion, the bias protrusion is installed at the optimal position for each blowout condition, increasing the deflection angle of the blowout flow and improving the velocity distribution of the blowout flow, thereby further enhancing the air conditioning effect. It becomes possible.

な効果を奏する。As shown in "Effects of the Invention", in the flow direction control device of the present invention, one wall of the blowout passage having a rectangular cross-sectional shape is formed by a flat wall, and the opposite wall is formed by a curved wall having a gradually enlarged shape. A flow control member is provided substantially parallel to the plane wall of the blowout passage and perpendicular to the flow, and the flow control member rotates about a rotation axis, and the center 0 is eccentric with respect to the rotation axis. The bias protrusion is a columnar body having a substantially arc-shaped head, one end of which is an extension of the head and the other is a bias action part and the other part is a substantially arc-shaped flow dividing part. Since the flow control member is configured to move substantially parallel to the flow direction in response to rotation of the flow control member, the following effects are achieved.

１）簡単な構成で大幅に流れを偏向させると共に、分流
動作を行なわせることができる。また、この時の風量を
殆ど低下させずに上記の動作を行なわせることができる
。1) With a simple configuration, it is possible to significantly deflect the flow and perform a diversion operation. Further, the above operation can be performed without substantially reducing the air volume at this time.

２）一本の軸の回転によって偏向及び分流動作を行なわ
せることができ、操作性が非常に良くなる。2) Deflection and shunt operations can be performed by rotating a single shaft, resulting in very good operability.

３）吹き出し状態に応じて、常に最適の位置にバイアス
突起を移動させ、吹き出し偏向角度の増大および吹き出
し速度分布の改善をはかることによって、空調効果を増
大させることができる。3) The air conditioning effect can be increased by always moving the bias protrusion to an optimal position depending on the blowout condition, increasing the blowout deflection angle and improving the blowout velocity distribution.
