Description

The present invention relates to a multi-branch chamber.

As a conventional multi-branch chamber, it is a branch chamber that sends gas blown from an air conditioner or the like through a duct in multiple directions. As a result, it is known that the air is uniformly blown to a plurality of discharge ports and the discharge with less pressure drop due to turbulent flow in the chamber is possible. (See, for example, Patent Document 1).

Hereinafter, the conventional multi-branch chamber will be described with reference to FIG.

FIG. 13 is a perspective view showing the inside of the multi-branch chamber 101 with the upper surface of the box removed. The supply port 103 on the supply surface 107 inside the box body 102, the first discharge port 104 on the opposite first discharge surface 108, and the second discharge on the second discharge surface 109 on the surface other than the first discharge port 104. A first outlet 105 having an outlet 105 and a third outlet 106 located closer to the supply port 103 than the second outlet 105, and an opening provided between the first outlet 104 and the second outlet 105. The adjustment wall 110 has a second adjustment wall 111 having an opening between the second discharge port 105 and the third discharge port 106, and the second adjustment wall 111 has an opening of the first adjustment wall 110. An opening having a lower aperture ratio is provided. An open portion 112 is provided around the second adjusting wall 111.

With the above configuration, the above-mentioned multi-branch chamber 101 functions as follows.

When there is no adjusting wall, a large amount of gas is discharged from the supply port 103 to the first discharge port 104 located opposite to the supply port 103, and the second is arranged on a surface other than the first discharge surface 108 where the first discharge port 104 is located. The amount of air discharged from the discharge port 105 is smaller than the amount of air discharged to the first discharge port 104. Therefore, by arranging the first adjusting wall 110 having an opening at a position between the first discharging port 104 and the second discharging port 105, the gas that has passed through the opening of the first adjusting wall 110 is discharged to the first discharging port. The gas discharged from 104 and blocked from passing by the first adjusting wall 110 is discharged from the second discharge port 105, which is not the first discharge port.

Further, since the third discharge port 106 is located on the supply port 103 side from the second discharge port 105, the gas is discharged to the third discharge port 106 while sending the gas to the second discharge port 105 and the first discharge port 104. Where necessary, the opening and the opening 112 can ensure the passage of gas to the second discharge port 105 and the first discharge port 104, which is blocked by the second adjusting wall 111 to the third discharge port 106. It is possible to adjust the amount of air discharged and the amount of discharge.

Then, by making the opening ratio of the opening of the second adjusting wall lower than that of the opening of the first adjusting wall,
It can be easily blocked by the second adjusting wall and can be easily discharged from the third discharge hole.

As a result, it is said that the effect of adjusting the air volume and making the discharge amount uniform is exhibited.

Even in such a conventional multi-branch chamber, it is possible to make the discharge flow rate uniform, but dust tends to accumulate in the opening of the adjusting wall, and the number of maintenance tends to increase. Further, it is necessary to arrange the discharge holes at different positions in the height direction, and there is also a problem that the arrangement on the ceiling or the floor surface is restricted.

Therefore, in the present invention, the flow dividing wall provided in the housing separates the air in the housing and makes the flow rate to be discharged uniform without increasing the number of maintenances and without being restricted by the arrangement in the height direction. It is an object of the present invention to provide a multi-branch chamber capable of providing a multi-branch chamber.

Further, the second inclined diversion wall 33 is located closer to the center of the inflow port 21 than the perpendicular line 52 located at the end of the inflow surface outflow port 24 side from the inflow surface 11 to the facing surface 12 on the downstream side, and the upstream side is the perpendicular line. It is arranged closer to the inflow surface and outflow port 24 than the 52.

In the multi-branch chamber 1 according to the sixth embodiment of the present invention, there are roughly three air flow flows. That is, the countercurrent outflow airflow 41 (countercurrent outflow airflow 41a, countercurrent outflow airflow 41b) flowing out from the above-mentioned countercurrent outflow port 22 and the side outflow airflow 42 (side outflow airflow 42a, outflow from the above-mentioned side outflow port 23). The side outflow airflow 42b, the side outflow airflow 42c, the side outflow airflow 42d), and the inflow surface outflow airflow 43 outflowing from the inflow surface outflow port 24.

The countercurrent outflow airflow 41 flows to the countercurrent outflow airflow 41a flowing to the countercurrent outflow port 22a on the side close to the inflow port 21 on the facing surface 12 and to the countercurrent outflow port 22b on the side far from the inflow port 21 on the facing surface 12. It is divided into airflow 41b.

In the countercurrent outflow airflow 41a, the air flowing in from the inflow port 21 is divided by the countercurrent diversion walls 31a and 31b provided with a predetermined interval, and the air flowing in the direction of the countercurrent surface 12 flows out from the countercurrent outflow port 22a. Is generated by.

In the countercurrent outflow airflow 41b, the air flowing in from the inflow port 21 is divided at the downstream end of the countercurrent diversion wall 31b and the second inclined diversion wall 33, and then divided at the upstream end of the first inclined diversion wall 32 beyond that. The downstream surface of the first inclined diversion wall 32 serves as a guide in the direction of the counter surface 12, and is generated by guiding the air flowing in the direction of the counter surface 12 to the counter flow outlet 22b.

The side outflow airflow 42 is close to the facing surface 12 and flows through the side outflow port 23a near the inflow port 21 and the side outflow airflow 42a near the facing surface 12 and far from the inflow port 21. The side outflow airflow 42b flowing through the inflow surface 11 and the side outflow airflow 42c near the inflow surface 11 and flowing through the side outflow port 23c near the inflow port 21 and the side flow near the inflow surface 11 and far from the inflow port 21. It is divided into a side outflow airflow 42d flowing through the outlet 23d.

The side outflow airflow 42a is generated by the air flowing in from the inflow port 21 flowing out from the side outflow port 23a through the air flowing between the side outflow surface 13a and the facing diversion wall 31a.

In the lateral outflow airflow 42b, the air flowing in from the inflow port 21 is divided at the downstream end of the opposite diversion wall 31b and the second inclined diversion wall 33, and then at the upstream end of the first inclined diversion wall 32 ahead of the split. It is divided, and the upstream surface of the first inclined diversion wall 32 serves as a guide in the direction of the side outflow surface 13b, and is generated by guiding the air guided in the direction of the side outflow surface 13b to the side outflow port 23b.

The side outflow airflow 42c is generated by the air flowing in from the inflow port 21 being divided by the facing diversion wall 31a and the air flowing in the direction of the side outflow surface 13a flowing out from the side outflow port 23c. ..

In the side outflow airflow 42d, the air flowing in from the inflow port 21 flows from the downstream side to the upstream side of the second inclined diversion wall 33, and the upstream surface of the second inclined diversion wall 33 flows out laterally to the inflow surface 11. It serves as a guide to the surface 13b and is generated by guiding the air flowing in the direction of the lateral outflow surface 13b to the side outlet 23d.

In the inflow surface outflow airflow 43, the air flowing in from the inflow port 21 flows from the downstream side to the upstream side of the second inclined diversion wall 33, and the upstream surface of the second inclined diversion wall 33 flows out laterally to the inflow surface 11. It serves as a guide to the surface 13b and is generated by guiding the air flowing in the direction of the inflow surface 11 to the inflow surface outflow port 24.

According to such a configuration, the length of the facing diversion wall 31 is set to an appropriate length and arranged at an appropriate interval, and the length of the first inclined diversion wall 32 is set to an appropriate length. By arranging at an appropriate angle, setting the length of the second inclined diversion wall 33 to an appropriate length, and arranging at an appropriate angle, the flow rate can be evenly distributed.

There is a strong tendency for the flow rate of 24 to decrease. In the above configuration, the flow rate can be evenly distributed to each of the other outlets.

Further, by adjusting the distance between the facing divergence wall 31, the first sloping divergence wall 32, and the second sloping divergence wall 33 from the inflow surface 11 instead of the length, the interval, and the angle, it is possible to reach each outlet with less resistance. The flow rate can be evenly distributed.

The side outflow airflow 42b, the side outflow airflow 42c, the side outflow airflow 42d, and the side outflow airflow 42e).

Next, the countercurrent outflow airflow 41 is applied to the countercurrent outflow airflow 41a flowing to the countercurrent outflow port 22a on the side close to the inflow port 21 on the facing surface 12 and the countercurrent outflow port 22b on the side far from the inflow port 21 on the facing surface 12. It is divided into a flowing countercurrent outflow airflow 41b.

Is generated by.

In the countercurrent outflow airflow 41b, the air flowing in from the inflow port 21 is divided at the upstream end of the countercurrent diversion wall 31b and the second inclined diversion wall 33, and then divided at the upstream end of the first inclined diversion wall 32 beyond that. The downstream surface of the first inclined diversion wall 32 serves as a guide in the direction of the counter surface 12, and is generated by guiding the air flowing in the direction of the counter surface 12 to the counter flow outlet 22b.

Next, the side outflow airflow 42 is close to the facing surface 12 and flows from the inflow port 21 to the nearby side outflow port 23a, and the side outflow airflow 42a is close to the facing surface 12 and far from the inflow port 21. The side outflow airflow 42b flowing through the outflow port 23b and the side outflow airflow 42c near the inflow surface 11 and flowing through the side outflow port 23c near the inflow port 21 and near the inflow surface 11 and far from the inflow port 21. It is divided into a side outflow airflow 42d flowing through the side outflow port 23d.

The side outflow airflow 42a is generated by the air flowing in from the inflow port 21 flowing out from the side outflow port 23a through the air flowing between the side outflow surface 13a and the facing diversion wall 31a.

In the side outflow airflow 42b, the air flowing in from the inflow port 21 flows from the downstream side to the upstream side along the second inclined diversion wall 33, and the upstream surface of the second inclined diversion wall 33 is directed to the side outflow surface 13b. It serves as a guide and is generated by guiding the air flowing in the direction of the side outflow surface 13b to the side outflow port 23b.

According to such a configuration, since the inflow surface outflow port 24 is sealed, the fluid that cannot flow from the second inclined diversion wall 33 in the inflow surface outflow port 24 direction flows in the facing surface 12 direction. Without the first inclined diversion wall 32, most of the fluid flowing in the direction of the facing surface 12 flows to the countercurrent outlet 22 on the counter surface 12, and a uniform flow rate to each outlet cannot be flowed. By providing the first inclined flow dividing wall 32, the fluid flowing in the direction of the facing surface 12 can flow in the direction of the side outflow surface 13b. Further, in order to suppress the side outflow airflow 42e that flows in the direction of the side outflow surface 13b, the side outflow airflow 42b that flows in the direction of the side outflow surface 13b is separated from the first inclined diversion wall 32 and tends to flow in the direction of the side outflow surface 13b. It is possible to prevent the flow rate flowing to the side outlet 23b on the side outflow surface 13b from becoming larger than that of the other outlets, and it flows to each outlet even when the inflow surface outlet 24 is sealed. The flow rate can be evenly distributed.

It is divided into a flowing countercurrent outflow airflow 41b.

In the countercurrent outflow airflow 41a, the air flowing in from the inflow port 21 is divided by the countercurrent diversion walls 31a and 31b provided with a predetermined interval, and the air flowing in the direction of the countercurrent surface 12 flows out from the countercurrent outflow port 22a. Is generated by.

In the countercurrent outflow airflow 41b, the air flowing in from the inflow port 21 is divided at the upstream end of the countercurrent diversion wall 31b and the second inclined diversion wall 33, and then divided at the upstream end of the first inclined diversion wall 32 beyond that. The downstream surface of the first inclined diversion wall 32 serves as a guide in the direction of the counter surface 12, and is generated by guiding the air flowing in the direction of the counter surface 12 to the counter flow outlet 22b.

Next, the side outflow airflow 42 is close to the facing surface 12 and flows from the inflow port 21 to the nearby side outflow port 23a, and the side outflow airflow 42a is close to the facing surface 12 and far from the inflow port 21. It is divided into a side outflow airflow 42b flowing through the outflow port 23b and a side outflow airflow 42c flowing through the side outflow port 23c near the inflow port 21 and near the inflow port 21.

The side outflow airflow 42a is generated by the air flowing in from the inflow port 21 flowing out from the side outflow port 23a through the air flowing between the side outflow surface 13a and the facing diversion wall 31a.

In the side outflow airflow 42b, the air flowing in from the inflow port 21 flows from the downstream side to the upstream side along the second inclined diversion wall 33, and the upstream surface of the second inclined diversion wall 33 is directed to the side outflow surface 13b.

According to such a configuration, since the inflow surface outflow port 24 and the side outflow port 23d are sealed, it is not possible to flow from the second inclined diversion wall 33 to the inflow surface outflow port 24 and the side outflow port 23d. The fluid flows in the facing surface 12 direction. Without the first inclined diversion wall 32, most of the fluid flowing in the direction of the facing surface 12 flows to the countercurrent outlet 22 on the counter surface 12, and a uniform flow rate to each outlet cannot be flowed. By providing the first inclined flow dividing wall 32, the fluid flowing in the direction of the facing surface 12 can flow in the direction of the side outflow surface 13b.

For example, when it is necessary to route the outflow duct in the same direction as the inflow duct, the pressure loss of the entire system including the duct can be reduced by allowing the duct to be routed with less bending. Make it possible.

Further, by aligning the center positions of the inflow port and the outflow port in the height direction, the height of the housing can be reduced, so that the installation restrictions in the height direction can be reduced.
