In the internal space of the housing 10a, a partition plate 10c is provided at the center in the longitudinal direction of the housing 10a. The partition plate 10c divides the internal space of the housing 10a into two spaces: a right space 10d, which is a space on the right side, and a left space 10e, which is a space on the left side.
図5Aに示すように、筐体10aの右端には開口10fが形成されており、右空間10dは開口10fを介して筐体10aの外部に連通している。図5Bに示すように、筐体10aの左端には開口10gが形成されており、左空間10eは開口10gを介して筐体10aの外部に連通している。

The housing 21a is connected to a duct (not shown), and air is supplied from the duct, and an air outlet 21c (see FIG. 3) is formed on the left side of the housing 21a. Then, the air blown out to the left from the air outlet 21c by the rotation of the fan 21b flows into the right space 10d through the opening 10f of each nozzle 10 of the nozzle unit 1. That is, the first nozzle blower 21 sends air from the opening 10f of each nozzle 10 to the right space 10d, thereby generating an internal airflow F11 (see FIG. 3) that flows from the opening 10f to the left in the right space 10d. . The internal airflow F11 is rectified by the fins 10h in the right space 10d, and is blown downward from the air outlet 10b on the lower surface of the housing 10a. Note that, as shown in FIG. 5A, it is preferable that the width of the lower part of the right space 10d in the front-rear direction becomes narrower as it goes downward.
第2ノズル送風機22は、クロスフローファンである。第2ノズル送風機22は、図2-図4に示すように、中空の矩形体状の筐体22aを備えて、筐体22aの内部にファン22bを有している。第2ノズル送風機22はノズルユニット1の左端(第2端)1bに設けられており、筐体22aの右面はノズルユニット1の左端面に対向している。筐体22aは図示しないダクトに接続して、ダクトから空気を供給され、筐体22aの右面には送風口22c(図3参照)が形成されている。そして、ファン22bが回転することで送風口22cから右方へ吹き出した空気は、ノズルユニット1の各ノズル10の開口10gを介して左空間10eに流れ込む。すなわち、第2ノズル送風機22は、各ノズル10の開口10fから左空間10eに空気を送り込むことで、左空間10eに開口10gから右方に向かって流れる内部気流F12(図3参照)を発生させる。内部気流F12は、左空間10e内のフィン10hによって整流されて、筐体10aの下面の送風口10bから下方に吹き出す。なお、図5Bに示すように、左空間10eの下部の前後方向の幅は、下へ向かうほど狭くなることが好ましい。
The second nozzle blower 22 is a cross flow fan. As shown in FIGS. 2 to 4, the second nozzle blower 22 includes a hollow rectangular housing 22a and a fan 22b inside the housing 22a. The second nozzle blower 22 is provided at the left end (second end) 1b of the nozzle unit 1, and the right surface of the housing 22a faces the left end surface of the nozzle unit 1. The housing 22a is connected to a duct (not shown), and air is supplied from the duct, and an air outlet 22c (see FIG. 3) is formed on the right side of the housing 22a. The air blown out to the right from the air outlet 22c as the fan 22b rotates flows into the left space 10e through the opening 10g of each nozzle 10 of the nozzle unit 1. That is, the second nozzle blower 22 sends air into the left space 10e from the opening 10f of each nozzle 10, thereby generating an internal airflow F12 (see FIG. 3) that flows from the opening 10g to the right in the left space 10e. . The internal airflow F12 is rectified by the fins 10h in the left space 10e, and is blown downward from the air outlet 10b on the lower surface of the housing 10a. Note that, as shown in FIG. 5B, it is preferable that the width of the lower part of the left space 10e in the front-rear direction becomes narrower toward the bottom.
すなわち、図6に示すように、ノズルユニット1を構成する8つのノズル10のそれぞれは、筐体10aの下面の長尺の送風口10bから下方へ空気を吹き出すことで、送風気流F2を生成する。なお、図6は、ノズルユニット1を構成する8つのノズル10のうち、Y軸に沿って前後方向に隣り合って配置されている任意の2つのノズル10を示す。
That is, as shown in FIG. 6, each of the eight nozzles 10 making up the nozzle unit 1 generates the air flow F2 by blowing air downward from the elongated air outlet 10b on the lower surface of the housing 10a. . In addition, FIG. 6 shows arbitrary two nozzles 10 which are arrange|positioned adjacently in the front-back direction along the Y-axis among the eight nozzles 10 which comprise the nozzle unit 1.
ここで、前後方向に隣り合う2つのノズル10の間には、図6に示す誘引経路91が形成されている。誘引経路91は、前側のノズル10の筐体10aの後面と後側のノズル10の筐体10aの前面とに前後から挟まれて、上方及び下方を開放した空間である。そして、並んで配置された2つのノズル10のそれぞれが送風口10bから下方へ吹き出す送風気流F2を生成すると、誘引経路91は負圧となり、誘引経路91には、2つのノズル10の上方の空間である上部空間92の空気が上から下に向かって誘引される。誘引経路91を上から下に向かって誘引された空気は、誘引経路91から下方に吹き出す。誘引経路91から下方に吹き出す空気は、誘引経路91から下に向かって流れる誘引気流F3を生成する。
Here, an attraction path 91 shown in FIG. 6 is formed between two nozzles 10 adjacent in the front-back direction. The attraction path 91 is a space that is sandwiched from the front and back between the rear surface of the casing 10a of the front nozzle 10 and the front surface of the casing 10a of the rear nozzle 10, and is open from above and below. Then, when each of the two nozzles 10 arranged side by side generates a blast air flow F2 blowing downward from the air outlet 10b, the attraction path 91 becomes a negative pressure, and the attraction path 91 has a space above the two nozzles 10. The air in the upper space 92 is drawn from top to bottom. The air attracted from the top to the bottom of the attraction path 91 is blown out from the attraction path 91 downward. The air blown downward from the attraction path 91 generates an attraction airflow F3 that flows downward from the attraction path 91.
この結果、ノズルユニット1の下方では、隣り合う2つのノズル10によって生成された2つの送風気流F2の間に誘引気流F3が発生し、送風気流F2と誘引気流F3とが合わさった下降気流F1が生成される。下降気流F1はノズルユニット1から下に向かって吹き出す。
As a result, below the nozzle unit 1, an induced airflow F3 is generated between the two blast airflows F2 generated by two adjacent nozzles 10, and a descending airflow F1 is created by combining the blast airflow F2 and the induced airflow F3. generated. The downdraft F1 is blown out from the nozzle unit 1 downward.
送風口10bにおける下降気流F1の流量をノズルユニット1の送風量とすると、ファン21b、22bの各回転速度が上昇する程、ノズルユニット1の送風量は増加し、ファン21b、22bの各回転速度が低下する程、ノズルユニット1の送風量は減少する。ファン21b、22bの各回転速度は、制御装置4によって制御される。
If the flow rate of the descending air flow F1 at the air outlet 10b is taken as the amount of air blown by the nozzle unit 1, the amount of air blown from the nozzle unit 1 increases as each rotational speed of the fans 21b and 22b increases, and each rotational speed of the fans 21b and 22b increases. As the value decreases, the amount of air blown from the nozzle unit 1 decreases. The rotational speeds of the fans 21b and 22b are controlled by the control device 4.
(2.2)送風装置
送風装置3は、クロスフローファンである。送風装置3は、ノズルユニット1の上方に配置されて、周囲の空気を吸い込んで、ノズルユニット1の右端(第1端)1aから左端(第2端)1bに向かって送風する。 (2.2) Air blower Theair blower 3 is a cross flow fan. The blower device 3 is arranged above the nozzle unit 1, sucks in surrounding air, and blows the air from the right end (first end) 1a to the left end (second end) 1b of the nozzle unit 1.
送風装置3は、クロスフローファンである。送風装置3は、ノズルユニット1の上方に配置されて、周囲の空気を吸い込んで、ノズルユニット1の右端(第1端)1aから左端(第2端)1bに向かって送風する。 (2.2) Air blower The
具体的に図3に示すように、送風装置3は、第1ノズル送風機21の上方(又はノズルユニット1の右端1aの上方)に配置されている。送風装置3は、天井R11の下面に図示しない吊りボルト又はワイヤなどで固定されている。送風装置3は、中空の矩形体状の筐体3aを備えて、筐体3aの内部にファン3bを有している。筐体3aの左面には送風口3cが形成されている。そして、ファン3bが回転することで送風口3cから左方へ吹き出した空気は、ノズルユニット1の上方を右から左へ向かって流れる送風気流F21となる。
Specifically, as shown in FIG. 3, the blower device 3 is arranged above the first nozzle blower 21 (or above the right end 1a of the nozzle unit 1). The blower device 3 is fixed to the lower surface of the ceiling R11 with a hanging bolt or wire (not shown). The blower device 3 includes a hollow rectangular housing 3a, and has a fan 3b inside the housing 3a. An air outlet 3c is formed on the left side of the housing 3a. The air blown out to the left from the air outlet 3c by the rotation of the fan 3b turns into an airflow F21 that flows above the nozzle unit 1 from right to left.
送風口3cにおける送風気流F21の流量を送風装置3の送風量とすると、ファン3bの回転速度が上昇する程、送風装置3の送風量は増加する。また、ファン3bの回転速度が低下する程、送風装置3の送風量は減少する。ファン3bの回転速度は、制御装置4によって制御される。
Assuming that the flow rate of the air flow F21 at the air outlet 3c is the amount of air blown by the blower 3, the amount of air blown by the blower 3 increases as the rotational speed of the fan 3b increases. Further, as the rotational speed of the fan 3b decreases, the amount of air blown by the air blower 3 decreases. The rotation speed of the fan 3b is controlled by the control device 4.

Further, the control device 4 acquires an operation signal from the operation terminal 5 and a sensor signal from the human sensor 6 by performing wired communication or wireless communication with the operation terminal 5 and the human sensor 6. . Note that the wired communication is, for example, wired communication via a twisted pair cable, a dedicated communication line, or a LAN (Local Area Network) cable. The wireless communication is, for example, wireless communication compliant with standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low power wireless that does not require a license (specific low power wireless).
操作端末5は、送風装置3、第1ノズル送風機21、及び第2ノズル送風機22の各動作を指示するためのスイッチ又はタッチパネルなどを備えており、ユーザの操作を受け付ける。そして、操作端末5は、ユーザの操作に応じた操作信号を制御装置4へ送信する。具体的に、操作端末5は、運転、停止、及び送風方向などの操作を受け付ける。制御装置4は、操作端末5から受け取った操作信号に基づいて、送風装置3、第1ノズル送風機21、及び第2ノズル送風機22のそれぞれの運転、停止、及び運転時の送風量を制御する。
The operating terminal 5 includes a switch or a touch panel for instructing each operation of the blower device 3, the first nozzle blower 21, and the second nozzle blower 22, and accepts user operations. The operation terminal 5 then transmits an operation signal according to the user's operation to the control device 4. Specifically, the operation terminal 5 accepts operations such as operation, stop, and direction of air blowing. Based on the operation signal received from the operation terminal 5, the control device 4 controls the operation and stop of each of the blower device 3, the first nozzle blower 21, and the second nozzle blower 22, and the amount of air blown during operation.
人感センサ6は、部屋R1内の人の有無、及び人の位置を検出し、検出結果をセンサ信号として制御装置4へ送信する。制御装置4は、人感センサ6から受け取ったセンサ信号に基づいて、送風装置3、第1ノズル送風機21、及び第2ノズル送風機22のそれぞれの運転、停止、及び運転時の送風量を制御する。
The human sensor 6 detects the presence or absence of a person in the room R1 and the position of the person, and transmits the detection result to the control device 4 as a sensor signal.

Therefore, the control device 4 controls the operation and operation of each of the blower device 3, the first nozzle blower 21, and the second nozzle blower 22 based on the user's operation received by the operation terminal 5 and the detection result of the human sensor 6. You can switch between stops and adjust the amount of air flow during each operation.
(2.4)送風システムの動作
送風システムVS1では、制御装置4が、送風装置3、第1ノズル送風機21、及び第2ノズル送風機22を制御することで、ノズルユニット1の下方に生成される気流の方向を調整する。本実施形態では、制御装置4は、第1ノズル送風機21及び第2ノズル送風機22をそれぞれ運転状態としたうえで、送風装置3の運転、停止、送風量を調整することで、ノズルユニット1の下方に生成される気流の方向(送風方向)を可変とする。 (2.4) Operation of the air blowing system In the air blowing system VS1, thecontrol device 4 controls the air blower 3, the first nozzle blower 21, and the second nozzle blower 22 to generate air below the nozzle unit 1. Adjust the direction of airflow. In this embodiment, the control device 4 puts the first nozzle blower 21 and the second nozzle blower 22 into operation, and then controls the operation, stopping, and air flow rate of the blower 3 to control the nozzle unit 1. The direction of the airflow generated downward (blow direction) is variable.
送風システムVS1では、制御装置4が、送風装置3、第1ノズル送風機21、及び第2ノズル送風機22を制御することで、ノズルユニット1の下方に生成される気流の方向を調整する。本実施形態では、制御装置4は、第1ノズル送風機21及び第2ノズル送風機22をそれぞれ運転状態としたうえで、送風装置3の運転、停止、送風量を調整することで、ノズルユニット1の下方に生成される気流の方向(送風方向)を可変とする。 (2.4) Operation of the air blowing system In the air blowing system VS1, the
(2.4.1)直下気流
図7は、第1ノズル送風機21及び第2ノズル送風機22が運転状態であり、送風装置3が停止状態であるときにノズルユニット1の下方に生成される気流である直下気流F31を示す。 (2.4.1) Airflow Directly Below FIG. 7 shows the airflow generated below thenozzle unit 1 when the first nozzle blower 21 and the second nozzle blower 22 are in operation and the blower 3 is in a stopped state. The airflow F31 directly below is shown.
図7は、第1ノズル送風機21及び第2ノズル送風機22が運転状態であり、送風装置3が停止状態であるときにノズルユニット1の下方に生成される気流である直下気流F31を示す。 (2.4.1) Airflow Directly Below FIG. 7 shows the airflow generated below the
この場合、下降気流F1がノズルユニット1から下方に吹き出している。一方、送風装置3の送風口3cからは、送風気流F21が吹き出していない。したがって、ノズルユニット1から下方に吹き出した下降気流F1は直下方向(鉛直下向き)に進み、ノズルユニット1の下方では、直下方向に進む直下気流F31が生成される。
In this case, the descending airflow F1 is blown downward from the nozzle unit 1. On the other hand, the air flow F21 is not blown out from the air outlet 3c of the air blower 3. Therefore, the descending airflow F1 blown downward from the nozzle unit 1 proceeds directly below (vertically downward), and below the nozzle unit 1, the downward airflow F31 that proceeds directly below is generated.
(2.4.2)斜め気流
図8は、第1ノズル送風機21及び第2ノズル送風機22が運転状態であり、かつ、送風装置3も運転状態であるときにノズルユニット1の下方に生成される気流である斜め気流F32を示す。 (2.4.2) Oblique airflow FIG. 8 shows the airflow generated below thenozzle unit 1 when the first nozzle blower 21 and the second nozzle blower 22 are in operation and the blower device 3 is also in operation. The oblique airflow F32 is shown as an airflow.
図8は、第1ノズル送風機21及び第2ノズル送風機22が運転状態であり、かつ、送風装置3も運転状態であるときにノズルユニット1の下方に生成される気流である斜め気流F32を示す。 (2.4.2) Oblique airflow FIG. 8 shows the airflow generated below the
この場合、下降気流F1がノズルユニット1から下方に吹き出している。また、ノズルユニット1の上方では、送風気流F21が送風装置3の送風口3cから左方へ吹き出している。ノズルユニット1の上方で右から左へ流れる送風気流F21は、ノズルユニット1から吹き出している下降気流F1に誘引されて下方へ引き寄せられ、前後方向に隣り合う2つのノズル10の間を通って左斜め下方向に進む。この結果、下降気流F1はノズルユニット1の下方で左斜め下方向に進む送風気流F21に誘引され、下降気流F1も左斜め下方向に進む。したがって、ノズルユニット1の下方では、左斜め下方向に進む斜め気流F32が生成される。
In this case, the descending airflow F1 is blown downward from the nozzle unit 1. Further, above the nozzle unit 1, a blowing air flow F21 is blown out from the blowing port 3c of the blowing device 3 to the left. The blast airflow F21 flowing from right to left above the nozzle unit 1 is attracted by the downward airflow F1 blowing out from the nozzle unit 1 and is pulled downward, passing between two nozzles 10 adjacent in the front and back direction and moving to the left. Proceed diagonally downward. As a result, the descending airflow F1 is attracted by the blowing airflow F21 that advances diagonally downward to the left below the nozzle unit 1, and the descending airflow F1 also advances diagonally downward to the left. Therefore, below the nozzle unit 1, an oblique airflow F32 that moves diagonally downward to the left is generated.
送風装置3の送風量が大きい程(送風気流F21の風量が大きい程)、斜め気流F32の進行方向は水平方向に近くなる。また、送風装置3の送風量が小さい程(送風気流F21の風量が小さい程)、斜め気流F32の進行方向は直下方向に近くなる。すなわち、制御装置4は、送風装置3の送風量を調整することで、斜め気流F32の進行方向を制御できる。
The larger the air volume of the air blower 3 (the larger the air volume of the air flow F21), the closer the direction of movement of the oblique air flow F32 becomes to the horizontal direction. Moreover, the smaller the air flow rate of the air blower 3 (the smaller the air flow rate of the air flow F21), the closer the direction of movement of the oblique air flow F32 becomes to the direct downward direction. That is, the control device 4 can control the traveling direction of the oblique airflow F32 by adjusting the amount of air blown by the blower 3.
(2.4.3)スイング気流
制御装置4は、送風装置3の運転及び停止を周期的に切り替えることで、直下気流F31(図7参照)と斜め気流F32(図8参照)とを周期的に切り替えることができる。この結果、送風システムVS1は、ノズルユニット1の下方において直下気流F31と斜め気流F32とが交互に発生するスイング気流を生成できる。 (2.4.3) Swing airflow Thecontrol device 4 periodically switches between operating and stopping the blower 3 to periodically control the direct airflow F31 (see Fig. 7) and the oblique airflow F32 (see Fig. 8). You can switch to As a result, the air blowing system VS1 can generate a swing airflow in which the direct airflow F31 and the oblique airflow F32 are alternately generated below the nozzle unit 1.
制御装置4は、送風装置3の運転及び停止を周期的に切り替えることで、直下気流F31(図7参照)と斜め気流F32(図8参照)とを周期的に切り替えることができる。この結果、送風システムVS1は、ノズルユニット1の下方において直下気流F31と斜め気流F32とが交互に発生するスイング気流を生成できる。 (2.4.3) Swing airflow The
また、制御装置4は、送風装置3の送風量を周期的に増減させることで、斜め気流F32(図8参照)の進行方向を周期的に変化させることができる。制御装置4は、送風装置3の送風量を増加させる増加期間と送風装置3の送風量を減少させる減少期間とを交互に繰り返す。この結果、送風システムVS1は、ノズルユニット1の下方において斜め気流F32の進行方向が連続的に変化するスイング気流を生成できる。
Furthermore, the control device 4 can periodically change the traveling direction of the oblique airflow F32 (see FIG. 8) by periodically increasing and decreasing the amount of air blown by the blower device 3. The control device 4 alternately repeats an increase period in which the amount of air blown by the air blower 3 is increased and a decrease period in which the amount of air blown by the air blower 3 is decreased. As a result, the air blowing system VS1 can generate a swing airflow in which the traveling direction of the oblique airflow F32 changes continuously below the nozzle unit 1.
なお、制御装置4は、送風装置3の送風量をゼロと目標値との間で周期的に増減させることで、直下気流F31と斜め気流F32との間で連続的に変化するスイング気流を実現できる。
In addition, the control device 4 realizes a swing airflow that continuously changes between the direct airflow F31 and the oblique airflow F32 by periodically increasing and decreasing the airflow amount of the airflow device 3 between zero and a target value. can.
上述のように、送風システムVS1では、制御装置4が送風装置3を制御することで、直下気流F31及び斜め気流F32を生成できる。また、制御装置4が送風装置3の運転及び停止を切り替えたり、送風装置3の送風量を周期的に変化させたりすることで、スイング気流を生成できる。すなわち、送風システムVS1は、ダンパ機構をノズルに設けることなく、送風方向を可変とすることができる。すなわち、送風システムVS1は、ノズル10の構造を簡易としながら送風方向を可変とすることができる。
As described above, in the blower system VS1, the control device 4 controls the blower device 3 to generate the direct airflow F31 and the diagonal airflow F32. Further, the swing airflow can be generated by the control device 4 switching between operating and stopping the blower device 3 or periodically changing the amount of air blown by the blower device 3. That is, the air blowing system VS1 can make the air blowing direction variable without providing a damper mechanism in the nozzle. That is, the air blowing system VS1 can make the air blowing direction variable while simplifying the structure of the nozzle 10.

送風ユニットU2は、第2ノズル送風機22の上方(又はノズルユニット1の左端1bの上方)に配置された送風装置3を、送風ユニットU1に追加したものである。なお、以下の説明では、第1ノズル送風機21の上方に配置された送風装置3を第1送風装置31とし、第2ノズル送風機22の上方に配置された送風装置3を第2送風装置32とする。
The blower unit U2 is obtained by adding a blower device 3 arranged above the second nozzle blower 22 (or above the left end 1b of the nozzle unit 1) to the blower unit U1. In the following description, the blower 3 placed above the first nozzle blower 21 will be referred to as the first blower 31, and the blower 3 placed above the second nozzle blower 22 will be referred to as the second blower 32. do.
第2送風装置32の筐体3aの右面には送風口3cが形成されている。そして、ファン3bが回転することで送風口3cから右方へ吹き出した空気は、ノズルユニット1の上方を左から右へ向かって流れる送風気流F22(図10参照)となる。
A ventilation port 3c is formed on the right side of the casing 3a of the second ventilation device 32. The air blown out to the right from the air outlet 3c by the rotation of the fan 3b becomes an airflow F22 (see FIG. 10) that flows above the nozzle unit 1 from left to right.
本変形例では、制御装置4が、操作端末5が受け付けたユーザの操作、及び人感センサ6の検出結果に基づいて、第1送風装置31、第2送風装置32、第1ノズル送風機21、及び第2ノズル送風機22のそれぞれの運転及び停止を切り替え、それぞれの運転時の送風量を調整することができる。そこで、制御装置4は、第1ノズル送風機21及び第2ノズル送風機22をそれぞれ運転状態としたうえで、第1送風装置31及び第2送風装置32の運転、停止、送風量を制御することで、ノズルユニット1の下方に生成される気流の方向(送風方向)を調整する。
In this modification, the control device 4 controls the first blower 31 , the second blower 32 , the first nozzle blower 21 , the first blower 31 , the second blower 32 , the first nozzle blower 21 , It is possible to switch between operation and stop of each of the second nozzle blowers 22 and adjust the amount of air blown during each operation. Therefore, the control device 4 puts the first nozzle blower 21 and the second nozzle blower 22 into operation, and then controls the operation, stopping, and air blowing amount of the first blower 31 and the second blower 32. , adjust the direction of airflow (blow direction) generated below the nozzle unit 1.
(3.1)直下気流
図11は、第1ノズル送風機21及び第2ノズル送風機22が運転状態であり、第1送風装置31及び第2送風装置32が停止状態であるときにノズルユニット1の下方に生成される気流である直下気流F41を示す。 (3.1) Airflow Directly Below FIG. 11 shows the flow of thenozzle unit 1 when the first nozzle blower 21 and the second nozzle blower 22 are in operation and the first blower 31 and second blower 32 are in a stopped state. A direct airflow F41, which is an airflow generated downward, is shown.
図11は、第1ノズル送風機21及び第2ノズル送風機22が運転状態であり、第1送風装置31及び第2送風装置32が停止状態であるときにノズルユニット1の下方に生成される気流である直下気流F41を示す。 (3.1) Airflow Directly Below FIG. 11 shows the flow of the
この場合、下降気流F1がノズルユニット1から下方に吹き出している。一方、第1送風装置31及び第2送風装置32の各送風口3cからは、送風気流F21、F22がそれぞれ吹き出していない。したがって、ノズルユニット1から下方に吹き出した下降気流F1は直下方向(鉛直下向き)に進み、ノズルユニット1の下方では、直下方向に進む直下気流F41が生成される。
In this case, the descending airflow F1 is blown downward from the nozzle unit 1. On the other hand, the airflows F21 and F22 are not blown out from the respective ventilation ports 3c of the first ventilation device 31 and the second ventilation device 32, respectively. Therefore, the downward airflow F1 blown downward from the nozzle unit 1 proceeds directly below (vertically downward), and below the nozzle unit 1, the downward airflow F41 that proceeds directly below is generated.
(3.2)第1斜め気流
図12は、第1ノズル送風機21及び第2ノズル送風機22が運転状態であり、かつ、第1送風装置31も運転状態であるときにノズルユニット1の下方に生成される気流である第1斜め気流F42を示す。このとき、第2送風装置32は停止状態である。 (3.2) First oblique airflow FIG. 12 shows the flow of air below thenozzle unit 1 when the first nozzle blower 21 and the second nozzle blower 22 are in operation, and the first blower 31 is also in operation. A first oblique airflow F42, which is a generated airflow, is shown. At this time, the second air blower 32 is in a stopped state.
図12は、第1ノズル送風機21及び第2ノズル送風機22が運転状態であり、かつ、第1送風装置31も運転状態であるときにノズルユニット1の下方に生成される気流である第1斜め気流F42を示す。このとき、第2送風装置32は停止状態である。 (3.2) First oblique airflow FIG. 12 shows the flow of air below the
この場合、下降気流F1がノズルユニット1から下方に吹き出している。また、ノズルユニット1の上方では、送風気流F21が第1送風装置31の送風口3cから左方へ吹き出している。ノズルユニット1の上方で右から左へ流れる送風気流F21は、ノズルユニット1から吹き出している下降気流F1に誘引されて下方へ引き寄せられ、前後方向に隣り合う2つのノズル10の間を通って左斜め下方向に進む。この結果、下降気流F1はノズルユニット1の下方で左斜め下方向に進む送風気流F21に誘引され、下降気流F1も左斜め下方向に進む。したがって、ノズルユニット1の下方では、左斜め下方向に進む第1斜め気流F42が生成される。
In this case, the descending airflow F1 is blown downward from the nozzle unit 1. Moreover, above the nozzle unit 1, the air flow F21 is blown out from the air outlet 3c of the first air blower 31 to the left. The blast airflow F21 flowing from right to left above the nozzle unit 1 is attracted by the downward airflow F1 blowing out from the nozzle unit 1 and is pulled downward, passing between two nozzles 10 adjacent in the front and back direction and moving to the left. Proceed diagonally downward. As a result, the descending airflow F1 is attracted by the blowing airflow F21 that advances diagonally downward to the left below the nozzle unit 1, and the descending airflow F1 also advances diagonally downward to the left. Therefore, below the nozzle unit 1, a first diagonal airflow F42 that moves diagonally downward to the left is generated.
第1送風装置31の送風量が大きい程(送風気流F21の風量が大きい程)、第1斜め気流F42の進行方向は水平方向に近くなる。また、第1送風装置31の送風量が小さい程(送風気流F21の風量が小さい程)、第1斜め気流F42の進行方向は直下方向に近くなる。すなわち、制御装置4は、第1送風装置31の送風量を調整することで、第1斜め気流F42の進行方向を制御できる。
The larger the air volume of the first air blower 31 (the larger the air volume of the air flow F21), the closer the traveling direction of the first oblique air flow F42 becomes to the horizontal direction. Furthermore, the smaller the air flow rate of the first air blower 31 (the smaller the air flow rate of the air flow F21), the closer the traveling direction of the first oblique air flow F42 becomes to the direct downward direction. That is, the control device 4 can control the traveling direction of the first oblique airflow F42 by adjusting the amount of air blown by the first air blower 31.
(3.3)第2斜め気流
図13は、第1ノズル送風機21及び第2ノズル送風機22が運転状態であり、かつ、第2送風装置32も運転状態であるときにノズルユニット1の下方に生成される気流である第2斜め気流F43を示す。このとき、第1送風装置31は停止状態である。 (3.3) Second oblique airflow FIG. 13 shows the flow of air below thenozzle unit 1 when the first nozzle blower 21 and the second nozzle blower 22 are in operation, and the second blower 32 is also in operation. A second oblique airflow F43, which is a generated airflow, is shown. At this time, the first air blower 31 is in a stopped state.
図13は、第1ノズル送風機21及び第2ノズル送風機22が運転状態であり、かつ、第2送風装置32も運転状態であるときにノズルユニット1の下方に生成される気流である第2斜め気流F43を示す。このとき、第1送風装置31は停止状態である。 (3.3) Second oblique airflow FIG. 13 shows the flow of air below the
この場合、下降気流F1がノズルユニット1から下方に吹き出している。また、ノズルユニット1の上方では、送風気流F22が第2送風装置32の送風口3cから右方へ吹き出している。ノズルユニット1の上方で左から右へ流れる送風気流F22は、ノズルユニット1から吹き出している下降気流F1に誘引されて下方へ引き寄せられ、前後方向に隣り合う2つのノズル10の間を通って右斜め下方向に進む。この結果、下降気流F1はノズルユニット1の下方で右斜め下方向に進む送風気流F22に誘引され、下降気流F1も右斜め下方向に進む。したがって、ノズルユニット1の下方では、右斜め下方向に進む第2斜め気流F43が生成される。
In this case, the descending airflow F1 is blown downward from the nozzle unit 1. Further, above the nozzle unit 1, a blowing air flow F22 is blown out to the right from the blowing port 3c of the second blowing device 32. The blast airflow F22 flowing from left to right above the nozzle unit 1 is attracted by the downward airflow F1 blowing out from the nozzle unit 1 and is drawn downward, passing between two nozzles 10 adjacent in the front and back direction and moving to the right. Proceed diagonally downward. As a result, the descending airflow F1 is attracted by the blowing airflow F22 that advances diagonally downward to the right below the nozzle unit 1, and the descending airflow F1 also advances diagonally downward to the right. Therefore, below the nozzle unit 1, a second oblique airflow F43 that moves diagonally downward to the right is generated.
第2送風装置32の送風量が大きい程(送風気流F22の風量が大きい程)、第2斜め気流F43の進行方向は水平方向に近くなる。また、第2送風装置32の送風量が小さい程(送風気流F22の風量が小さい程)、第2斜め気流F43の進行方向は直下方向に近くなる。すなわち、制御装置4は、第2送風装置32の送風量を調整することで、第2斜め気流F43の進行方向を制御できる。
The larger the air volume of the second air blower 32 (the larger the air volume of the air flow F22), the closer the traveling direction of the second oblique air flow F43 becomes to the horizontal direction. Moreover, the smaller the air flow rate of the second air blower 32 (the smaller the air flow rate of the air flow F22), the closer the traveling direction of the second oblique air flow F43 becomes to the direct downward direction. That is, the control device 4 can control the traveling direction of the second oblique airflow F43 by adjusting the amount of air blown by the second blower 32.
(3.4)スイング気流
制御装置4は、第1送風装置31及び第2送風装置32のそれぞれの運転及び停止を切り替えることができる。そこで、制御装置4は、第1送風装置31の運転期間と第2送風装置32の運転期間とを交互に切り替えることで、第1斜め気流F42(図12参照)と第2斜め気流F43(図13参照)とを周期的に切り替えることが好ましい。この結果、送風システムVS1は、ノズルユニット1の下方において第1斜め気流F42と第2斜め気流F43とが交互に発生するスイング気流を生成できる。すなわち、送風システムVS1は、第1送風装置31及び第2送風装置32を制御することで、送風方向の可変範囲を拡げることができる。 (3.4) Swing Air Flow Thecontrol device 4 can switch between operation and stop of each of the first blower device 31 and the second blower device 32. Therefore, the control device 4 alternately switches the operating period of the first blower 31 and the second blower 32 to create a first diagonal airflow F42 (see FIG. 12) and a second diagonal airflow F43 (see FIG. 13)) is preferably switched periodically. As a result, the blower system VS1 can generate a swing airflow in which the first oblique airflow F42 and the second oblique airflow F43 are alternately generated below the nozzle unit 1. That is, the ventilation system VS1 can expand the variable range of the ventilation direction by controlling the first ventilation device 31 and the second ventilation device 32.
制御装置4は、第1送風装置31及び第2送風装置32のそれぞれの運転及び停止を切り替えることができる。そこで、制御装置4は、第1送風装置31の運転期間と第2送風装置32の運転期間とを交互に切り替えることで、第1斜め気流F42(図12参照)と第2斜め気流F43(図13参照)とを周期的に切り替えることが好ましい。この結果、送風システムVS1は、ノズルユニット1の下方において第1斜め気流F42と第2斜め気流F43とが交互に発生するスイング気流を生成できる。すなわち、送風システムVS1は、第1送風装置31及び第2送風装置32を制御することで、送風方向の可変範囲を拡げることができる。 (3.4) Swing Air Flow The
また、制御装置4は、第1送風装置31の運転期間と第2送風装置32の運転期間とを交互に切り替える際に、第1送風装置31の運転期間と第2送風装置32の運転期間との間に、第1送風装置31と第2送風装置32との両方を停止させる全停止期間を設けてもよい。この場合、送風システムVS1は、ノズルユニット1の下方において第1斜め気流F42→直下気流F41→第2斜め気流F43→直下気流F41→第1斜め気流F42の順に繰り返し発生するスイング気流を実現できる。したがって、送風システムVS1は、滑らかなスイング気流を生成できる。
Moreover, when the control device 4 alternately switches the operating period of the first air blower 31 and the operating period of the second air blower 32, the control device 4 controls the operation period of the first air blower 31 and the operation period of the second air blower 32. In between, a full stop period may be provided in which both the first blower 31 and the second blower 32 are stopped. In this case, the air blowing system VS1 can realize a swing airflow that repeatedly occurs below the nozzle unit 1 in the order of the first oblique airflow F42→directly below airflow F41→second oblique airflow F43→directly below airflow F41→first oblique airflow F42. Therefore, the ventilation system VS1 can generate a smooth swing airflow.
また、制御装置4は、第1送風装置31の運転期間において、第1送風装置31の送風量をゼロから第1目標値まで増加させた後に、ゼロまで減少させることが好ましい。この場合、ノズルユニット1の下方において第1斜め気流F42の進行方向が連続的に変化する。同様に、制御装置4は、第2送風装置32の運転期間において、第2送風装置32の送風量をゼロから第2目標値まで増加させた後に、ゼロまで減少させることが好ましい。この場合、ノズルユニット1の下方において第2斜め気流F43の進行方向が連続的に変化する。したがって、送風システムVS1は、送風方向を滑らかに変化させることができ、第1斜め気流F42及び第2斜め気流F43の各進行方向が連続的に変化するスイング気流を実現できる。
Furthermore, it is preferable that the control device 4 increases the air flow rate of the first air blower 31 from zero to the first target value, and then decreases it to zero during the operation period of the first air blower 31. In this case, the traveling direction of the first oblique airflow F42 changes continuously below the nozzle unit 1. Similarly, during the operation period of the second blower 32, the control device 4 preferably increases the amount of air blown by the second blower 32 from zero to the second target value, and then decreases it to zero. In this case, the traveling direction of the second oblique airflow F43 changes continuously below the nozzle unit 1. Therefore, the air blowing system VS1 can smoothly change the air blowing direction, and can realize a swing airflow in which the traveling directions of the first oblique airflow F42 and the second oblique airflow F43 change continuously.
具体的に、第1送風装置31の運転期間では、第1斜め気流F42の進行方向は、直下方向から左方向に徐々に変化した後、左方向から直下方向に徐々に戻る。第1斜め気流F42の進行方向が直下方向に戻ると、第1送風装置31の運転期間が終了し、第2送風装置32の運転期間が開始される。第2送風装置32の運転期間では、第2斜め気流F43の進行方向は、直下方向から右方向に徐々に変化した後、右方向から直下方向に徐々に戻る。第2斜め気流F43の進行方向が直下方向に戻ると、第2送風装置32の運転期間が終了し、第1送風装置31の運転期間が開始される。前述の動作を繰り返すことで、第1斜め気流F42及び第2斜め気流F43の各進行方向が連続的に変化するスイング気流が実現される。
Specifically, during the operation period of the first blower device 31, the traveling direction of the first oblique airflow F42 gradually changes from directly below to the left, and then gradually returns from the left to directly below. When the traveling direction of the first oblique airflow F42 returns to the direct downward direction, the operating period of the first air blower 31 ends, and the operating period of the second air blower 32 begins. During the operation period of the second blower device 32, the traveling direction of the second oblique airflow F43 gradually changes from directly below to the right, and then gradually returns from the right to directly below. When the traveling direction of the second oblique airflow F43 returns to the direct downward direction, the operating period of the second blower 32 ends, and the operating period of the first blower 31 starts. By repeating the above-described operation, a swing airflow in which the traveling directions of the first oblique airflow F42 and the second oblique airflow F43 change continuously is realized.
また、制御装置4は、第1送風装置31の送風量と第2送風装置32の送風量との比率を連続的に調整することで、スイング気流の送風方向を連続的に変化させてもよい。
Further, the control device 4 may continuously change the blowing direction of the swing airflow by continuously adjusting the ratio between the blowing amount of the first blowing device 31 and the blowing amount of the second blowing device 32. .
上述のように、第1変形例では、制御装置4が第1送風装置31及び第2送風装置32を制御することで、直下気流F41、第1斜め気流F42、及び第2斜め気流F43を生成できる。また、制御装置4が第1送風装置31及び第2送風装置32の運転及び停止を切り替えたり、第1送風装置31及び第2送風装置32の各送風量を周期的に変化させたりすることで、スイング気流を生成できる。すなわち、送風システムVS1は、ダンパ機構をノズルに設けることなく、送風方向を可変とすることができる。すなわち、送風システムVS1は、ノズル10の構造を簡易としながら送風方向を可変とすることができる。
As described above, in the first modification, the control device 4 controls the first blower 31 and the second blower 32 to generate the direct airflow F41, the first diagonal airflow F42, and the second diagonal airflow F43. can. In addition, the control device 4 switches between operating and stopping the first blower device 31 and the second blower device 32, or periodically changes the amount of air blown by the first blower device 31 and the second blower device 32. , can generate swing airflow. That is, the air blowing system VS1 can make the air blowing direction variable without providing a damper mechanism in the nozzle. That is, the air blowing system VS1 can make the air blowing direction variable while simplifying the structure of the nozzle 10.
