Case 211 includes a top wall 21a and a side wall 21b. The ceiling wall 21a has a square plate shape extending in the direction along the XY plane. The periphery of the ceiling wall 21a has two pairs of side parts facing each other, one set facing in the left-right direction along the X-axis, and the other set facing in the front-back direction along the Y-axis. . Rectangular plate-shaped side walls 21b extend from the four sides of the ceiling wall 21a in a direction intersecting the ceiling wall 21a (in the present embodiment, a direction perpendicular to the ceiling wall 21a).
　そして、ケース２１１は、フレーム２１３を覆うように、枠体２１２に上方から嵌め込まれる。 Then, the case 211 is fitted into the frame body 212 from above so as to cover the frame 213.
　このように構成された筐体２１の内部には、図１－図３に示すように、ケース２１１の天壁２１ａ及び側壁２１ｂ、並びに枠体２１２の基部２１ｍ、に囲まれた矩形体状の内部空間２１０が形成される。内部空間２１０の上面は、天壁２１ａで覆われている。内部空間２１０の左、右、前、後の各側面は、天壁２１ａの四辺から下方に向かって延びる各側壁２１ｂで覆われている。 As shown in FIGS. 1 to 3, inside the case 21 configured in this way, there is a rectangular body surrounded by the top wall 21a and side wall 21b of the case 211, and the base 21m of the frame 212. An internal space 210 is formed. The upper surface of the internal space 210 is covered with a ceiling wall 21a. The left, right, front, and rear sides of the interior space 210 are covered with side walls 21b extending downward from the four sides of the ceiling wall 21a.
　図４及び図５に示すように、天壁２１ａの中央には、円筒部２１ｃが設けられている。円筒部２１ｃの中心軸はＺ軸に沿っており、円筒部２１ｃの内部は、断面円形状の吸気口２１ｄを構成している。吸気口２１ｄは、Ｚ軸に沿った上下方向を中心軸とする断面円形状である。 As shown in FIGS. 4 and 5, a cylindrical portion 21c is provided at the center of the ceiling wall 21a. The central axis of the cylindrical portion 21c is along the Z-axis, and the inside of the cylindrical portion 21c constitutes an intake port 21d having a circular cross section. The air intake port 21d has a circular cross section whose central axis is in the vertical direction along the Z-axis.
　吸気口２１ｄには、フランジ２２が取り付けられる。フランジ２２は、例えばポリプロピレン樹脂で形成されている。フランジ２２は、円筒状の筒体２２ａ、及び鍔部２２ｂを備える。鍔部２２ｂは、筒体２２ａの下端から筒体２２ａの外側に向かって延びる円形の枠状に形成されている。フランジ２２は、筒体２２ａが吸気口２１ｄに対して同軸に位置するように、吸気口２１ｄにインサート成形されている。筒体２２ａは吸気口２１ｄを挿通し、筒体２２ａの上端は、吸気口２１ｄの上端より上方に突出している。鍔部２２ｂは、円筒部２１ｃの内側面に係止して、フランジ２２が吸気口２１ｄから抜けることを防止する抜け止めとして機能する。そして、筒体２２ａの上端側はダクト３の端部に嵌め込まれている。吸気口２１ｄの下端は内部空間２１０に空間的に連続している。ダクト３を流れる供給空気Ａ１は、筒体２２ａ及び吸気口２１ｄを通って内部空間２１０に上から下に向かって吹き出る。 A flange 22 is attached to the intake port 21d. The flange 22 is made of polypropylene resin, for example. The flange 22 includes a cylindrical body 22a and a flange 22b. The flange portion 22b is formed in a circular frame shape extending from the lower end of the cylindrical body 22a toward the outside of the cylindrical body 22a. The flange 22 is insert-molded in the intake port 21d such that the cylindrical body 22a is located coaxially with the intake port 21d. The cylindrical body 22a is inserted through the intake port 21d, and the upper end of the cylindrical body 22a projects upward from the upper end of the intake port 21d. The flange portion 22b engages with the inner surface of the cylindrical portion 21c and functions as a retainer to prevent the flange 22 from coming off from the intake port 21d. The upper end side of the cylindrical body 22a is fitted into the end of the duct 3. The lower end of the intake port 21d is spatially continuous with the internal space 210. The supply air A1 flowing through the duct 3 blows out from above into the internal space 210 through the cylinder 22a and the intake port 21d.
　そして、ケース２１１の下端は、枠体２１２に上から嵌まり込む。枠体２１２の基部２１ｍの上面には、ケース２１１の側壁２１ｂの下端が接し、立壁２１ｎの内周面には、側壁２１ｂの側面が接する。また、基部２１ｍは、ケース２１１の側壁２１ｂの下端によって形成される矩形状の開口２１ｆを狭めるように、Ｘ－Ｙ平面に沿う方向に延びている。そして、基部２１ｍに囲まれた矩形状の開口が、矩形状の送風口２１ｅを構成する。すなわち、基部２１ｍは、内部空間２１０を送風口２１ｅの周縁に向かって狭める絞り部２１ｇとして機能する。絞り部２１ｇは、送風口２１ｅから吹き出す送風空気Ａ２を指向性気流とする機能を有する。 Then, the lower end of the case 211 fits into the frame 212 from above. The lower end of the side wall 21b of the case 211 is in contact with the upper surface of the base 21m of the frame 212, and the side surface of the side wall 21b is in contact with the inner peripheral surface of the vertical wall 21n. Furthermore, the base 21m extends in the direction along the XY plane so as to narrow the rectangular opening 21f formed by the lower end of the side wall 21b of the case 211. A rectangular opening surrounded by the base 21m constitutes a rectangular air outlet 21e. That is, the base portion 21m functions as a constriction portion 21g that narrows the internal space 210 toward the periphery of the air outlet 21e. The throttle part 21g has a function of making the blown air A2 blown out from the air outlet 21e into a directional airflow.
　（２．２．２）支持台
　図４及び図５に示すように、送風装置２は、４つの支持台２５を備える。４つの支持台２５は、４本のスペーサ２１４にそれぞれ取り付けられている。 (2.2.2) Support Stands As shown in FIGS. 4 and 5, the blower device 2 includes four support stands 25. The four support stands 25 are attached to the four spacers 214, respectively.
　図８に示すように、支持台２５は矩形体形状である。支持台２５には、上下方向に延びる挿通孔２５ａが形成されている。支持台２５は、挿通孔２５ａにスペーサ２１４を挿通させることで、スペーサ２１４に取り付けられる。 As shown in FIG. 8, the support stand 25 has a rectangular shape. The support base 25 is formed with an insertion hole 25a that extends in the vertical direction. The support stand 25 is attached to the spacer 214 by inserting the spacer 214 into the insertion hole 25a.
　支持台２５の第１側面２５ｅには溝部２５ｂが形成されている。溝部２５ｂは、Ｘ－Ｙ平面に沿って延びる矩形体状の溝である。溝部２５ｂには、整流板２３の取付片２３ｄが嵌まり込む。すなわち、溝部２５ｂは、整流板２３を支持する支持部として機能する。 A groove 25b is formed on the first side surface 25e of the support base 25. The groove portion 25b is a rectangular groove extending along the XY plane. The mounting piece 23d of the current plate 23 fits into the groove 25b. That is, the groove portion 25b functions as a support portion that supports the current plate 23.
　また、図８に示すように、支持台２５の第１側面２５ｅには、駆動部２７が２本のスペーサ２５ｃを介して図示しないねじで取り付けられる。さらに、支持台２５の第２側面２５ｆ（第１側面２５ｅに直交する面）には円柱状の突部２５ｄが形成されている。 Further, as shown in FIG. 8, the drive unit 27 is attached to the first side surface 25e of the support base 25 with screws (not shown) via two spacers 25c. Furthermore, a cylindrical protrusion 25d is formed on the second side surface 25f (the surface perpendicular to the first side surface 25e) of the support base 25.
　そして、隣り合う２つの支持台２５について、一方の支持台２５の第１側面２５ｅと他方の支持台２５の第２側面２５ｆとが互いに対向している。 Regarding the two adjacent support stands 25, the first side surface 25e of one support stand 25 and the second side surface 25f of the other support stand 25 face each other.
　（２．２．３）整流板
　図４、図５及び図７に示すように、整流板２３は、ほぼ正方形の平板状であり、例えばポリプロピレン樹脂を材料とする樹脂成型によって生成されている。 (2.2.3) Current Plate As shown in FIGS. 4, 5, and 7, the current plate 23 has a substantially square flat plate shape, and is produced by resin molding using, for example, polypropylene resin.
　具体的に、整流板２３は、正方形の板状のプレート２３ａ、及びプレート２３ａの四隅のそれぞれから突出している取付片２３ｄを備える。プレート２３ａは、厚み方向に対向する第１面（上面）２３ｂ及び第２面（下面）２３ｃを備える。 Specifically, the current plate 23 includes a square plate-shaped plate 23a and mounting pieces 23d protruding from each of the four corners of the plate 23a. The plate 23a includes a first surface (upper surface) 23b and a second surface (lower surface) 23c that face each other in the thickness direction.
　取付片２３ｄは、プレート２３ａの四隅のそれぞれから外側に延びている。そして、取付片２３ｄは、支持台２５の第１側面２５ｅに形成された溝部２５ｂ（図１、図７及び図８参照）に嵌め込まれる。取付片２３ｄが溝部２５ｂに嵌め込まれることで、整流板２３が支持台２５に取り付けられ、内部空間２１０における整流板２３の位置決めがなされる。しかして、整流板２３は、第１面２３ｂが吸気口２１ｄに対向し、第２面２３ｃが送風口２１ｅに対向するように内部空間２１０内に配置される。このとき、整流板２３は、平面視において送風口２１ｅを覆っている。この結果、下方から内部空間２１０の全体を視認し難くなり、送風装置２の意匠性が向上する。 The mounting pieces 23d extend outward from each of the four corners of the plate 23a. The mounting piece 23d is fitted into a groove 25b (see FIGS. 1, 7, and 8) formed on the first side surface 25e of the support base 25. By fitting the attachment piece 23d into the groove 25b, the current plate 23 is attached to the support base 25, and the current plate 23 is positioned in the internal space 210. Thus, the current plate 23 is arranged in the internal space 210 so that the first surface 23b faces the air intake port 21d and the second surface 23c faces the air outlet 21e. At this time, the current plate 23 covers the air outlet 21e in plan view. As a result, the entire interior space 210 is difficult to see from below, and the design of the blower device 2 is improved.
　また、整流板２３は、硬質発泡スチロールより硬いポリプロピレン樹脂で形成されている。この結果、送風装置２は、内部空間２１０を流れる供給空気Ａ１が整流板２３に衝突することによって、整流板２３に応力が発生しても、重量化を抑えながら整流板２３の撓みを抑制することができる。 Furthermore, the current plate 23 is made of polypropylene resin which is harder than hard styrofoam. As a result, even if stress is generated in the current plate 23 due to the supply air A1 flowing through the internal space 210 colliding with the current plate 23, the blower device 2 can suppress deflection of the current plate 23 while suppressing weight increase. be able to.
　（２．２．４）駆動部
　図４、図５及び図７に示すように、送風装置２は、４枚の板部材２６をそれぞれ個別に開閉駆動する駆動部として、４つの駆動部２７を備える。４つの駆動部２７は、４つの支持台２５にそれぞれ取り付けられている。 (2.2.4) Drive unit As shown in FIGS. 4, 5, and 7, the blower device 2 has four drive units 27 that individually drive the four plate members 26 to open and close.

　円柱体状のカバー２７ａの一対の端面を第１端面及び第２端面とすると、第１端面は支持台２５の第１側面２５ｅに接し、第２端面からは一対の取付片２７ｄが第２端面の径方向に突出している。一対の取付片２７ｄは、図示しないねじによって、２本のスペーサ２５ｃを介して支持台２５の第１側面２５ｅに取り付けられる。すなわち、カバー２７ａは、支持台２５の第１側面２５ｅに固定される。さらに、カバー２７ａの第２端面からは、第２端面の法線方向に駆動軸２７ｃが突出している。 Assuming that the pair of end faces of the cylindrical cover 27a are a first end face and a second end face, the first end face is in contact with the first side face 25e of the support base 25, and a pair of mounting pieces 27d are attached to the second end face from the second end face. protrudes in the radial direction. The pair of attachment pieces 27d are attached to the first side surface 25e of the support base 25 via the two spacers 25c with screws (not shown).

The left side portion 23e, the front side portion 23f, the right side portion 23g, and the rear side portion 23h are opposed to the four side walls 21b of the housing 21, respectively.
　そして、連通部２４は、左辺部２３ｅ、前辺部２３ｆ、右辺部２３ｇ、後辺部２３ｈと４つの側壁２１ｂ（の内面）との間に形成されて、吸気口２１ｄから送風口２１ｅに向かう供給空気Ａ１が流れる流路を構成する。すなわち、連通部２４は、内部空間２１０において、整流板２３の外縁に沿って整流板２３の外側に形成されている。 The communication portion 24 is formed between the left side portion 23e, the front side portion 23f, the right side portion 23g, the rear side portion 23h, and (the inner surfaces of) the four side walls 21b, and extends from the air intake port 21d to the air outlet 21e. It constitutes a flow path through which supply air A1 flows. That is, the communication portion 24 is formed outside the current plate 23 along the outer edge of the current plate 23 in the internal space 210 .
　連通部２４は、左辺部２３ｅに沿って形成された連通部２４１、前辺部２３ｆに沿って形成された連通部２４２、右辺部２３ｇに沿って形成された連通部２４３、後辺部２３ｈに沿って形成された連通部２４４を含む。 The communication portion 24 includes a communication portion 241 formed along the left side portion 23e, a communication portion 242 formed along the front side portion 23f, a communication portion 243 formed along the right side portion 23g, and a communication portion 243 formed along the rear side portion 23h. It includes a communication portion 244 formed along.
　（２．２．６）板部材
　図４、図５及び図７に示すように、送風装置２は、４枚の板部材２６を備える。板部材２６は、長尺の矩形板状の羽根部２６ａを有する所謂フラップである。羽根部２６ａの一面では、羽根部２６ａの長手方向の第１端に軸接続部２６ｂが形成され、羽根部２６ａの長手方向の第２端に軸受け２６ｃが形成されている。そして、板部材２６は、隣り合う２つの支持台２５の間に取り付けられる。具体的に、板部材２６の軸接続部２６ｂは、一方の支持台２５に取り付けられている駆動部２７の駆動軸２７ｃを保持し、板部材２６の軸受け２６ｃは、他方の支持台２５の突部２５ｄを回転自在に支持する。すなわち、隣り合う２つの支持台２５の間に設けられた板部材２６は、一方の支持台２５に取り付けられている駆動部２７によって回転駆動される。 (2.2.6) Plate Members As shown in FIGS. 4, 5, and 7, the blower device 2 includes four plate members 26. The plate member 26 is a so-called flap having a long rectangular plate-shaped wing portion 26a. On one surface of the blade portion 26a, a shaft connection portion 26b is formed at a first longitudinal end of the blade portion 26a, and a bearing 26c is formed at a second longitudinal end of the blade portion 26a. Then, the plate member 26 is attached between two adjacent support stands 25. Specifically, the shaft connection part 26b of the plate member 26 holds the drive shaft 27c of the drive part 27 attached to one support stand 25, and the bearing 26c of the plate member 26 holds the drive shaft 27c of the drive part 27 attached to one support stand 25. The portion 25d is rotatably supported. That is, the plate member 26 provided between two adjacent supports 25 is rotationally driven by the drive unit 27 attached to one of the supports 25 .
　そして、駆動部２７の駆動軸２７ｃが第１方向に回転すると、板部材２６は、羽根部２６ａが連通部２４を塞ぐ閉位置に変位する。駆動部２７の駆動軸２７ｃが第２方向（第１方向の逆方向）に回転すると、板部材２６は、羽根部２６ａが連通部２４を開放する開位置に変位する。すなわち、板部材２６は、羽根部２６ａが連通部２４を塞ぐ閉位置と羽根部２６ａが連通部２４を開放する開位置との間で回転変位する。板部材２６が閉位置にあれば、板部材２６の羽根部２６ａの面は水平方向（Ｘ－Ｙ平面に沿う方向）に沿っている。板部材２６が開位置にあれば、板部材２６の羽根部２６ａの面は鉛直方向（Ｚ軸に沿う方向）に沿っている。 Then, when the drive shaft 27c of the drive section 27 rotates in the first direction, the plate member 26 is displaced to the closed position where the blade section 26a closes the communication section 24. When the drive shaft 27c of the drive section 27 rotates in the second direction (the opposite direction to the first direction), the plate member 26 is displaced to the open position where the blade section 26a opens the communication section 24. That is, the plate member 26 is rotationally displaced between a closed position where the blade portion 26a closes the communication portion 24 and an open position where the blade portion 26a opens the communication portion 24.

In this embodiment, the control device K1 individually controls the displacement of each of the plate members 261-264 by individually controlling each of the drive units 271-274.
　制御装置Ｋ１は、コンピュータシステムを備えることが好ましい。すなわち、制御装置Ｋ１では、ＣＰＵ（Central Processing Unit）、又はＭＰＵ（Micro Processing Unit）などのプロセッサがメモリに記憶されているプログラムを読み出して実行することによって、制御装置Ｋ１の一部又は全部の機能が実現される。コンピュータシステムは、プログラムに従って動作するプロセッサを主なハードウェア構成として備える。プロセッサは、プログラムを実行することによって機能を実現することができれば、その種類は問わない。プロセッサは、半導体集積回路（ＩＣ）、又はＬＳＩ（Large Scale Integration）を含む一つ又は複数の電子回路で構成される。ここでは、ＩＣやＬＳＩと呼んでいるが、集積の度合いによって呼び方が変わり、システムＬＳＩ、ＶＬＳＩ（Very Large Scale Integration）、若しくはＵＬＳＩ（Ultra Large Scale Integration）と呼ばれるものであってもよい。ＬＳＩの製造後にプログラムされる、フィールド・プログラマブル・ゲート・アレイ(FPGA)、又はＬＳＩ内部の接合関係の再構成又はＬＳＩ内部の回路区画のセットアップができる再構成可能な論理デバイスも同じ目的で使うことができる。複数の電子回路は、一つのチップに集積されてもよいし、複数のチップに設けられてもよい。複数のチップは集約して配置されてもよいし、分散して配置されてもよい。 It is preferable that the control device K1 includes a computer system. That is, in the control device K1, a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) reads and executes a program stored in a memory, thereby controlling some or all of the functions of the control device K1. is realized. A computer system includes, as its main hardware configuration, a processor that operates according to a program. The type of processor does not matter as long as it can implement a function by executing a program. A processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integration (LSI). Here, it is called an IC or LSI, but the name changes depending on the degree of integration, and it may also be called a system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Field programmable gate arrays (FPGAs), which are programmed after the LSI is manufactured, or reconfigurable logic devices that can reconfigure the interconnections within the LSI or set up circuit sections within the LSI, may also be used for the same purpose. I can do it. A plurality of electronic circuits may be integrated on one chip or may be provided on a plurality of chips. The plurality of chips may be arranged in a concentrated manner or may be arranged in a dispersed manner.

Moreover, the control device K1 may be constructed as a cloud computing system.
　制御装置Ｋ１は、送風装置２との間で、有線通信又は無線通信を行うことで、送風装置２の駆動部２７１－２７４を個別に制御する。なお、有線通信は、例えばツイストペアケーブル、専用通信線、またはＬＡＮ（Local Area Network）ケーブルなどを介した有線通信である。無線通信は、例えばWi-Fi（登録商標）、又は免許を必要としない小電力無線（特定小電力無線）等の規格に準拠した無線通信である。 The control device K1 individually controls the drive units 271 to 274 of the blower device 2 by performing wired or wireless communication with the blower device 2. 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 based on a standard such as Wi-Fi (registered trademark) or low power wireless that does not require a license (specified low power wireless).
　具体的に、制御装置Ｋ１は、空調空間９における人の位置、及び温度分布などに基づいて、送風装置２の駆動部２７１－２７４を個別に制御することで、４枚の板部材２６１－２６４を個別に開閉させる。すなわち、制御装置Ｋ１は、送風装置２が吹き出す送風空気Ａ２の送風方向を調整する。 Specifically, the control device K1 controls the four plate members 261-264 by individually controlling the drive units 271-274 of the blower device 2 based on the position of the person in the air-conditioned space 9, the temperature distribution, etc. open and close individually. That is, the control device K1 adjusts the direction of the blown air A2 blown out by the blowing device 2.
　また、制御装置Ｋ１は、ユーザの手動操作によって、送風装置２の駆動部２７１－２７４を個別に制御してもよい。この場合、ユーザは、送風装置２の動作を指示する専用のリモートコントローラ、並びに専用のアプリケーションをインストールしたスマートフォン及びタブレット端末などの操作端末を操作することで、送風空気Ａ２の送風方向を制御装置Ｋ１に指示する。制御装置Ｋ１は、操作端末の指示に応じて、送風空気Ａ２の送風方向を調整する。 Furthermore, the control device K1 may individually control the drive units 271-274 of the blower device 2 through manual operation by the user. In this case, the user controls the blowing direction of the blowing air A2 from the control device K1 by operating a dedicated remote controller that instructs the operation of the blower device 2, and an operation terminal such as a smartphone or tablet device on which a dedicated application is installed. instruct. The control device K1 adjusts the blowing direction of the blowing air A2 according to instructions from the operating terminal.

が考えられる。 The opening/closing pattern of the four plate members 26 is as follows:
- First pattern: four plate members 26 in open position - Second pattern: three plate members 26 in open position, one plate member 26 in closed position - Third pattern: two adjacent plate members 26 is in the open position, the other two plate members 26 are in the closed position.Fourth pattern: One plate member 26 is in the open position, three plate members 26 are in the closed position.Fifth pattern: Four plate members are in the closed position. 26 is considered to be in the closed position.
　以下、第１パターン－第５パターンのそれぞれにおける送風方向について説明する。なお、図１５は、空調空間９を上方から見た平面図であり、空調空間９において送風装置２から吹き出した送風空気Ａ２が向かう送風ポイント（地点）を示す。 Hereinafter, the air blowing direction in each of the first pattern to the fifth pattern will be explained. Note that FIG. 15 is a plan view of the air-conditioned space 9 viewed from above, and shows a blowing point (point) toward which the blown air A2 blown from the blower 2 in the air-conditioned space 9 is directed.
　［第１パターン］
　第１パターンは、図１０に示すように、４枚の板部材２６が開位置にある。この場合、連通部２４１－２４４は開放されている。したがって、吸気口２１ｄから内部空間２１０に上から下に向かって供給された供給空気Ａ１は、整流板２３の第１面２３ｂに沿って左方向、右方向、前方向、及び後方向に向かい、連通部２４１－２４４を上から下に向かって通過した後、整流板２３の第２面２３ｃと絞り部２１ｇ（基部２１ｍ）との間を、連通部２４１－２４４からプレート２３ａの中心に向かって進む。プレート２３ａの下方では、連通部２４１－２４４からプレート２３ａの中心に向かって進む供給空気Ａ１が互いに衝突し、この結果、送風装置２は、送風口２１ｅから直下に向かって送風空気Ａ２を吹き出す。すなわち、送風方向は送風口２１ｅの直下になり、送風空気Ａ２は、送風口２１ｅの直下の送風ポイントＰ１（図１５参照）に向かって進む。 [First pattern]
In the first pattern, as shown in FIG. 10, the four plate members 26 are in the open position. In this case, communication portions 241-244 are open. Therefore, the supply air A1 supplied from the intake port 21d to the internal space 210 from above to the bottom goes toward the left, right, front, and rear along the first surface 23b of the current plate 23, After passing through the communication parts 241-244 from top to bottom, it passes between the second surface 23c of the current plate 23 and the constriction part 21g (base 21m) from the communication parts 241-244 toward the center of the plate 23a. move on. Below the plate 23a, the supply air A1 traveling toward the center of the plate 23a from the communication portions 241-244 collides with each other, and as a result, the blower device 2 blows out the blow air A2 directly below from the air outlet 21e. That is, the blowing direction is directly below the blowing port 21e, and the blowing air A2 advances toward the blowing point P1 (see FIG. 15) directly below the blowing port 21e.
　［第２パターン］
　第２パターンは、３枚の板部材２６が開位置、１枚の板部材２６が閉位置にある。一例として、図１２に示すように、３枚の板部材２６１、２６２、２６４が開位置、１枚の板部材２６３が閉位置にある、とする。この場合、連通部２４１、２４２、２４４は開放され、連通部２４３は塞がれている。したがって、吸気口２１ｄから内部空間２１０に上から下に向かって供給された供給空気Ａ１は、整流板２３の第１面２３ｂに沿って左方向、前方向、及び後方向に向かい、連通部２４１、２４２、２４４を上から下に向かって通過した後、整流板２３の第２面２３ｃと絞り部２１ｇ（基部２１ｍ）との間を、連通部２４１、２４２、２４４からプレート２３ａの中心に向かって進む。プレート２３ａの下方では、連通部２４１、２４２、２４４からプレート２３ａの中心に向かって進む供給空気Ａ１が互いに衝突し、この結果、送風装置２は、送風口２１ｅから右斜め下に向かって送風空気Ａ２を吹き出す。すなわち、送風方向は送風口２１ｅの右斜め下になり、送風空気Ａ２は、送風口２１ｅの右斜め下の送風ポイントＰ２１（図１５参照）に向かって進む。 [Second pattern]
In the second pattern, three plate members 26 are in the open position and one plate member 26 is in the closed position. As an example, as shown in FIG. 12, assume that three plate members 261, 262, and 264 are in the open position, and one plate member 263 is in the closed position. In this case, communication portions 241, 242, and 244 are open, and communication portion 243 is closed. Therefore, the supply air A1 supplied from the intake port 21d to the internal space 210 from above to the bottom is directed to the left, the front, and the rear along the first surface 23b of the baffle plate 23, and flows toward the communication portion 241. , 242, 244 from top to bottom, and then passes between the second surface 23c of the rectifier plate 23 and the constricted portion 21g (base portion 21m) from the communicating portions 241, 242, 244 toward the center of the plate 23a. Proceed. Below the plate 23a, the supply air A1 traveling from the communication parts 241, 242, 244 toward the center of the plate 23a collides with each other, and as a result, the blower device 2 blows air diagonally downward to the right from the air outlet 21e. Blow out A2. That is, the air blowing direction is diagonally to the lower right of the air outlet 21e, and the blown air A2 advances toward the air blowing point P21 (see FIG. 15) which is diagonally to the lower right of the air outlet 21e.
　なお、３枚の板部材２６１、２６２、２６３が開位置、１枚の板部材２６４が閉位置にある場合、送風方向は送風口２１ｅの後ろ斜め下になり、送風空気Ａ２は、送風口２１ｅの後ろ斜め下の送風ポイントＰ２２（図１５参照）に向かって進む。 Note that when the three plate members 261, 262, and 263 are in the open position and the one plate member 264 is in the closed position, the air blowing direction is diagonally downward behind the air outlet 21e, and the blown air A2 is directed toward the air outlet 21e. Proceed toward the ventilation point P22 (see FIG. 15) diagonally below and behind the.
　また、３枚の板部材２６２、２６３、２６４が開位置、１枚の板部材２６１が閉位置にある場合、送風方向は送風口２１ｅの左斜め下になり、送風空気Ａ２は、送風口２１ｅの左斜め下の送風ポイントＰ２３（図１５参照）に向かって進む。 Further, when the three plate members 262, 263, and 264 are in the open position and one plate member 261 is in the closed position, the air blowing direction is diagonally below and to the left of the air outlet 21e, and the air A2 is blown into the air outlet 21e. Proceed toward the ventilation point P23 (see FIG. 15) diagonally below and to the left of the screen.
　また、３枚の板部材２６１、２６３、２６４が開位置、１枚の板部材２６２が閉位置にある場合、送風方向は送風口２１ｅの前斜め下になり、送風空気Ａ２は、送風口２１ｅの前斜め下の送風ポイントＰ２４（図１５参照）に向かって進む。 Further, when the three plate members 261, 263, and 264 are in the open position and one plate member 262 is in the closed position, the air blowing direction is diagonally below the front of the air outlet 21e, and the air A2 is blown into the air outlet 21e.

　第３パターンは、隣り合う２枚の板部材２６が開位置、残りの２枚の板部材２６が閉位置にある。一例として、図１３に示すように、２枚の板部材２６１、２６４が開位置、２枚の板部材２６２、２６３が閉位置にある、とする。この場合、連通部２４１、２４４は開放され、連通部２４２、２４３は塞がれている。したがって、吸気口２１ｄから内部空間２１０に上から下に向かって供給された供給空気Ａ１は、整流板２３の第１面２３ｂに沿って左方向、及び後方向に向かい、連通部２４１、２４４を上から下に向かって通過した後、整流板２３の第２面２３ｃと絞り部２１ｇ（基部２１ｍ）との間を、連通部２４１、２４４からプレート２３ａの中心に向かって進む。プレート２３ａの下方では、連通部２４１、２４４からプレート２３ａの中心に向かって進む供給空気Ａ１が互いに衝突し、この結果、送風装置２は、送風口２１ｅから右前に向かって送風空気Ａ２を吹き出す。すなわち、送風方向は送風口２１ｅの右前になり、送風空気Ａ２は、送風口２１ｅの右前の送風ポイントＰ３１（図１５参照）に向かって進む。 [Third pattern]
In the third pattern, two adjacent plate members 26 are in the open position and the remaining two plate members 26 are in the closed position. As an example, as shown in FIG. 13, it is assumed that two plate members 261 and 264 are in the open position and two plate members 262 and 263 are in the closed position. In this case, communication portions 241 and 244 are open, and communication portions 242 and 243 are closed. Therefore, the supply air A1 supplied to the internal space 210 from above to the bottom from the intake port 21d heads leftward and rearward along the first surface 23b of the current plate 23, and passes through the communication portions 241 and 244. After passing from the top to the bottom, it passes between the second surface 23c of the rectifying plate 23 and the constricted portion 21g (base portion 21m) from the communicating portions 241 and 244 toward the center of the plate 23a. Below the plate 23a, the supply air A1 traveling from the communication portions 241 and 244 toward the center of the plate 23a collides with each other, and as a result, the blower device 2 blows out the blow air A2 toward the front right from the blower port 21e. That is, the air blowing direction is to the right front of the air outlet 21e, and the blown air A2 advances toward the air blowing point P31 (see FIG. 15) at the right front of the air outlet 21e.
　なお、２枚の板部材２６１、２６２が開位置、２枚の板部材２６３、２６４が閉位置にある場合、送風方向は送風口２１ｅの右後ろになり、送風空気Ａ２は、送風口２１ｅの右後ろの送風ポイントＰ３２（図１５参照）に向かって進む。 Note that when the two plate members 261 and 262 are in the open position and the two plate members 263 and 264 are in the closed position, the air blowing direction is to the right rear of the air outlet 21e, and the air A2 is directed to the right side of the air outlet 21e. Proceed toward the ventilation point P32 (see FIG. 15) on the rear right.
　また、２枚の板部材２６２、２６３が開位置、２枚の板部材２６１、２６４が閉位置にある場合、送風方向は送風口２１ｅの左後ろになり、送風空気Ａ２は、送風口２１ｅの左後ろの送風ポイントＰ３３（図１５参照）に向かって進む。 Furthermore, when the two plate members 262 and 263 are in the open position and the two plate members 261 and 264 are in the closed position, the air blowing direction is to the rear left of the air outlet 21e, and the air A2 is blown to the left of the air outlet 21e. Proceed toward the ventilation point P33 (see FIG. 15) on the rear left.
　また、２枚の板部材２６３、２６４が開位置、２枚の板部材２６１、２６２が閉位置にある場合、送風方向は送風口２１ｅの左前になり、送風空気Ａ２は、送風口２１ｅの左前の送風ポイントＰ３４（図１５参照）に向かって進む。 Further, when the two plate members 263 and 264 are in the open position and the two plate members 261 and 262 are in the closed position, the air blowing direction is to the left front of the air outlet 21e, and the blown air A2 is to the left front of the air outlet 21e. Proceed toward the ventilation point P34 (see FIG. 15).
　［第４パターン］
　第４パターンは、１枚の板部材２６が開位置、３枚の板部材２６が閉位置にある。一例として、図１４に示すように、１枚の板部材２６１が開位置、３枚の板部材２６２、２６３、２６４が閉位置にある、とする。この場合、連通部２４１は開放され、連通部２４２、２４３、２４４は塞がれている。したがって、吸気口２１ｄから内部空間２１０に上から下に向かって供給された供給空気Ａ１は、整流板２３の第１面２３ｂに沿って左方向に向かい、連通部２４１を上から下に向かって通過した後、整流板２３の第２面２３ｃと絞り部２１ｇ（基部２１ｍ）との間を、連通部２４１からプレート２３ａの中心に向かって進む。この結果、送風装置２は、送風口２１ｅから右に向かって送風空気Ａ２を吹き出す。すなわち、送風方向は送風口２１ｅの右になり、送風空気Ａ２は、送風口２１ｅの右の送風ポイントＰ４１（図１５参照）に向かって進む。 [4th pattern]
In the fourth pattern, one plate member 26 is in the open position and three plate members 26 are in the closed position. As an example, as shown in FIG. 14, it is assumed that one plate member 261 is in the open position and three plate members 262, 263, and 264 are in the closed position. In this case, the communicating portion 241 is open, and the communicating portions 242, 243, and 244 are closed. Therefore, the supply air A1 supplied from the intake port 21d to the internal space 210 from above to the bottom moves leftward along the first surface 23b of the current plate 23, and flows through the communication portion 241 from above to the bottom. After passing through, it advances from the communication part 241 toward the center of the plate 23a between the second surface 23c of the current plate 23 and the constricted part 21g (base part 21m). As a result, the blower device 2 blows out the blowing air A2 toward the right from the blower port 21e. That is, the blowing direction is to the right of the blowing port 21e, and the blowing air A2 advances toward the blowing point P41 (see FIG. 15) to the right of the blowing port 21e.
　なお、１枚の板部材２６２が開位置、３枚の板部材２６１、２６３、２６４が閉位置にある場合、送風方向は送風口２１ｅの後ろになり、送風空気Ａ２は、送風口２１ｅの後ろの送風ポイントＰ４２（図１５参照）に向かって進む。 Note that when one plate member 262 is in the open position and the three plate members 261, 263, and 264 are in the closed position, the air blowing direction is behind the air outlet 21e, and the blown air A2 is behind the air outlet 21e. The vehicle advances toward the ventilation point P42 (see FIG. 15).
　また、１枚の板部材２６３が開位置、３枚の板部材２６１、２６２、２６４が閉位置にある場合、送風方向は送風口２１ｅの左になり、送風空気Ａ２は、送風口２１ｅの左の送風ポイントＰ４３（図１５参照）に向かって進む。 Further, when one plate member 263 is in the open position and three plate members 261, 262, and 264 are in the closed position, the air blowing direction is to the left of the air outlet 21e, and the blown air A2 is to the left of the air outlet 21e. Proceed toward the ventilation point P43 (see FIG. 15).
　また、１枚の板部材２６４が開位置、３枚の板部材２６１、２６２、２６３が閉位置にある場合、送風方向は送風口２１ｅの前になり、送風空気Ａ２は、送風口２１ｅの前の送風ポイントＰ４４（図１５参照）に向かって進む。 Further, when one plate member 264 is in the open position and three plate members 261, 262, and 263 are in the closed position, the air blowing direction is in front of the air outlet 21e, and the blown air A2 is in front of the air outlet 21e. Proceed toward the ventilation point P44 (see FIG. 15).
　［第５パターン］
　第５パターンは、図１１に示すように、４枚の板部材２６が閉位置にある。この場合、連通部２４１－２４４は塞がっている。したがって、吸気口２１ｄから内部空間２１０に上から下に向かって供給された供給空気Ａ１は、連通部２４１－２４４を通過し難くなり、送風口２１ｅからの送風空気Ａ２の吹き出しは停止する。 [Fifth pattern]
In the fifth pattern, as shown in FIG. 11, the four plate members 26 are in the closed position. In this case, the communication portions 241-244 are closed. Therefore, the supply air A1 supplied from the intake port 21d to the internal space 210 from above to the bottom becomes difficult to pass through the communication portions 241-244, and the blowing of the blown air A2 from the ventilation port 21e is stopped.
　［小括］
　上述のように、送風装置２は、４枚の板部材２６の開閉パターンを第１パターン－第５パターンから選択することで、送風空気Ａ２の送風方向を細かく調整できる。 [Brief Summary]
As described above, the blowing device 2 can finely adjust the blowing direction of the blowing air A2 by selecting the opening/closing pattern of the four plate members 26 from the first pattern to the fifth pattern.
　さらに、第１パターン－第４パターンのそれぞれでは、平面視における送風空気Ａ２の到達距離も異なる。第１パターンの送風ポイントＰ１、第２パターンの送風ポイントＰ２１－Ｐ２４、第３パターンの送風ポイントＰ３１－Ｐ３４、第４パターンの送風ポイントＰ４１－Ｐ４４のうち、送風ポイントＰ１が送風装置２にも最も近く、送風ポイントＰ４１－Ｐ４４が送風装置２から最も遠い。送風ポイントＰ２１－Ｐ２４は送風装置２に２番目に近く、送風ポイントＰ３１－Ｐ３４は送風装置２に３番目に近くなる。すなわち、第１パターン、第２パターン、第３パターン、第４パターンの順に、送風ポイントが送風装置２から徐々に遠くなり、送風空気Ａ２の送風方向をより細かく調整することができる。 Further, the reach distance of the blown air A2 in plan view is also different between the first pattern and the fourth pattern. Among the ventilation points P1 of the first pattern, the ventilation points P21-P24 of the second pattern, the ventilation points P31-P34 of the third pattern, and the ventilation points P41-P44 of the fourth pattern, the ventilation point P1 is the most suitable for the ventilation device 2. Nearby, the ventilation points P41-P44 are farthest from the ventilation device 2. The ventilation points P21-P24 are the second closest to the ventilation device 2, and the ventilation points P31-P34 are the third closest to the ventilation device 2. That is, in the order of the first pattern, the second pattern, the third pattern, and the fourth pattern, the ventilation point becomes gradually farther away from the ventilation device 2, and the direction of the ventilation air A2 can be adjusted more finely.
　平面視において、送風装置２と送風ポイントＰ２１－Ｐ２４との各距離をＬ２、送風装置２と送風ポイントＰ３１－Ｐ３４との各距離をＬ３、送風装置２と送風ポイントＰ４１－Ｐ４４との各距離をＬ４とする（図１５参照）。一例では、距離Ｌ２は１ｍ、距離Ｌ３は２ｍ、距離Ｌ４は３ｍになる。また、一例では、送風ポイントＰ４１－Ｐ４４のそれぞれを頂点とする正方形の１辺の距離Ｌａは４．５ｍになる。 In plan view, each distance between the ventilation device 2 and ventilation points P21-P24 is L2, each distance between the ventilation device 2 and ventilation points P31-P34 is L3, and each distance between the ventilation device 2 and ventilation points P41-P44 is Let it be L4 (see FIG. 15). In one example, the distance L2 is 1 m, the distance L3 is 2 m, and the distance L4 is 3 m. Further, in one example, the distance La of one side of a square having each of the ventilation points P41 to P44 as its apex is 4.5 m.
　また、送風装置２は、板部材２６を変位させることで送風空気Ａ２の送風方向を調整している。一方、整流板２３を変位させることで送風空気Ａ２の送風方向を調整する機構も考えられる。しかしながら、整流板２３を変位させるための機構は、板部材２６を変位させるための機構よりも複雑になりやすい。しかして、送風装置２は、板部材２６を変位させる機構を採用することで、簡易かつ軽量な構造で送風空気Ａ２の送風方向を調整できる。 Furthermore, the blower device 2 adjusts the direction of the blowing air A2 by displacing the plate member 26. On the other hand, a mechanism for adjusting the direction of the blown air A2 by displacing the rectifying plate 23 is also conceivable. However, the mechanism for displacing the current plate 23 tends to be more complicated than the mechanism for displacing the plate member 26. By employing a mechanism for displacing the plate member 26, the blower device 2 can adjust the blowing direction of the blowing air A2 with a simple and lightweight structure.
　また、送風装置２は、４枚の板部材２６を備えることで、送風空気Ａ２の送風方向を細かく調整することができる。さらに、送風装置２は、駆動部２７１－２７４によって、４枚の板部材２６１－２６４を個別に開閉駆動することで、送風空気Ａ２の送風方向をより細かく調整することができる。例えば、４枚の板部材２６のそれぞれを個別の開閉制御することで、空調空間９内における送風ポイントを所望の位置に調整できる。例えば、送風ポイントを１箇所に固定してピンポイントで送風したり、送風ポイントを連続的に移動させたりできる。 Furthermore, by including the four plate members 26, the blower device 2 can finely adjust the direction of the blowing air A2. Furthermore, the blowing device 2 can more finely adjust the blowing direction of the blowing air A2 by individually driving the four plate members 261-264 to open and close using the drive units 271-274. For example, by individually controlling the opening and closing of each of the four plate members 26, the ventilation point within the air-conditioned space 9 can be adjusted to a desired position. For example, the ventilation point can be fixed at one location and the ventilation can be pinpointed, or the ventilation point can be moved continuously.
