　しかしながら、このような従来の換気装置では、冬期に居室空間を換気すると、居室空間を利用する人物の身体全体に気流が当たり、利用者が寒く感じてしまうため、快適に過ごすことが難しいという問題があった。 However, with such conventional ventilation systems, when ventilating a room in winter, the airflow hits the entire body of the person using the room, making the user feel cold and making it difficult to stay comfortable.
　本開示は、居室空間における送風装置において、通年で快適性を保ちながら換気可能な技術を提供するものである。 This disclosure provides a technology for a blower in a living space that allows ventilation while maintaining comfort all year round.
　本開示に係る送風装置は、利用者が着座可能な着座部を有する居室空間において、利用者の頭上となる居室空間の天面側から送風を行う送風装置であって、居室空間の天面側に配置され、居室空間の天面側から居室空間の床面側に向かって流れる空気を吹き出すスリット状の吹出口をそれぞれが有する４つ以上の吹出ノズルと、居室空間の外部から居室空間内へ空気を供給するための給気口と、居室空間内から外部へ空気を放出するための排気口と、給気口から供給された空気を吸い込み、吸い込んだ空気を４つ以上の吹出ノズルに向けてそれぞれ送風する４つ以上の送風機と、４つ以上の送風機の動作を制御する制御部と、を備える。４つ以上の吹出ノズルは、それぞれの吹出口が同一面上に位置するように間隙を有して並設されて送風面を構成する。制御部は、４つ以上の吹出ノズルのうち、着座部に着座した利用者の鉛直方向上方に位置する１または複数の吹出ノズルを第１吹出ノズルとして特定し、４つ以上の吹出ノズルのうち、第１吹出ノズル以外の１または複数の吹出ノズルを第２吹出ノズルとして特定し、給気口から吸い込まれた空気を第１吹出ノズルおよび第２吹出ノズルに送風する第１送風モードと、給気口から吸い込まれた空気を第１吹出ノズルに送風せずに第２吹出ノズルに選択的に送風する第２送風モードと、を切り替えて４つ以上の送風機の動作を制御する。 The air blower device according to the present disclosure is an air blower device that blows air from the ceiling side of a living space above a user's head in a living space having a seating portion on which a user can sit, and is equipped with four or more blowing nozzles that are arranged on the ceiling side of the living space and each have a slit-shaped blowing outlet that blows out air flowing from the ceiling side of the living space toward the floor side of the living space, an air intake port for supplying air from outside the living space into the living space, an exhaust port for discharging air from inside the living space to the outside, four or more blowers that suck in air supplied from the air intake port and blow the sucked air toward the four or more blowing nozzles, and a control unit that controls the operation of the four or more blowers.

　本開示に係る送風装置は、利用者が着座可能な着座部を有する居室空間において、利用者の頭上となる居室空間の天面側から送風を行う送風装置であって、居室空間の天面側に配置され、居室空間の天面側から居室空間の床面側に向かって流れる空気を吹き出すスリット状の吹出口をそれぞれが有する４つ以上の吹出ノズルと、居室空間の外部から居室空間内へ空気を供給するための給気口と、居室空間内から外部へ空気を放出するための排気口と、給気口から供給された空気を吸い込み、吸い込んだ空気を４つ以上の吹出ノズルに向けてそれぞれ送風する４つ以上の送風機と、４つ以上の送風機の動作を制御する制御部と、を備える。４つ以上の吹出ノズルは、それぞれの吹出口が同一面上に位置するように間隙を有して並設されて送風面を構成する。制御部は、４つ以上の吹出ノズルのうち、着座部に着座した利用者の鉛直方向上方に位置する１または複数の吹出ノズルを第１吹出ノズルとして特定し、４つ以上の吹出ノズルのうち、第１吹出ノズル以外の１または複数の吹出ノズルを第２吹出ノズルとして特定し、給気口から吸い込まれた空気を第１吹出ノズルおよび第２吹出ノズルに送風する第１送風モードと、給気口から吸い込まれた空気を第１吹出ノズルに送風せずに第２吹出ノズルに選択的に送風する第２送風モードと、を切り替えて４つ以上の送風機の動作を制御する。 The air blower device according to the present disclosure is an air blower device that blows air from the ceiling side of a living space above a user's head in a living space having a seating portion on which a user can sit, and is equipped with four or more blowing nozzles that are arranged on the ceiling side of the living space and each have a slit-shaped blowing outlet that blows out air flowing from the ceiling side of the living space toward the floor side of the living space, an air intake port for supplying air from outside the living space into the living space, an exhaust port for discharging air from inside the living space to the outside, four or more blowers that suck in air supplied from the air intake port and blow the sucked air toward the four or more blowing nozzles, and a control unit that controls the operation of the four or more blowers. The four or more blowing nozzles are arranged side by side with gaps between them so that their respective blowing outlets are located on the same plane, forming an air blowing surface. The control unit identifies one or more of the four or more blowing nozzles that are located vertically above the user seated on the seat as a first blowing nozzle, and identifies one or more of the four or more blowing nozzles other than the first blowing nozzle as a second blowing nozzle, and controls the operation of the four or more blowers by switching between a first blowing mode in which air drawn in from the air intake is blown to the first blowing nozzle and the second blowing nozzle, and a second blowing mode in which air drawn in from the air intake is selectively blown to the second blowing nozzle without being blown to the first blowing nozzle.
　こうした構成によれば、送風モードを切り替えることによって、第１送風モードにおいては、利用者の鉛直方向上方から空気を吹き出し、利用者に直進的に当たる気流を形成しながら送風を行い、第２送風モードにおいては、利用者の鉛直方向上方以外の領域から空気を吹き出し、利用者に気流を当てずに送風を行うことができる。 With this configuration, by switching the airflow mode, in the first airflow mode, air is blown out from above the user in the vertical direction, creating an airflow that hits the user in a straight line, while in the second airflow mode, air is blown out from an area other than above the user in the vertical direction, allowing air to be blown without hitting the user.
　これにより、居室空間内の換気（居室空間外から取り込んだ空気を居室空間内へ送風し、居室空間内の空気を入れ替える）をする際に、居室空間内に漫然と空気を送風するのではなく、冬期においては、第２送風モードに切り替えて、着座した利用者を避けた送風を行うようにできる。一方、夏期においては、第１送風モードに切り替えて、着座した利用者に向けて送風を行うようにできる。 As a result, when ventilating the living space (air taken in from outside the living space is blown into the living space to replace the air within the living space), rather than blowing air randomly into the living space, in winter the mode can be switched to the second air blowing mode so that air is blown away from seated occupants. Meanwhile, in summer the mode can be switched to the first air blowing mode so that air is blown toward seated occupants.
　よって、冬期には、利用者に気流が当たって利用者が寒く感じてしまうことが抑制され、夏期には、利用者に気流が当たって利用者に涼しく感じさせることができる。つまり、居室空間における送風装置において、通年で快適性を保ちながら換気することができる。 As a result, in the winter, the air current hitting the user and making the user feel cold is suppressed, and in the summer, the air current hitting the user makes the user feel cool. In other words, the air blower in the living space can ventilate while maintaining comfort all year round.
　また、本開示に係る送風装置では、制御部は、第１送風モードにおいて、第１吹出ノズルの吹出口から吹き出す空気の風量が、第２吹出ノズルの吹出口から吹き出す空気の風量よりも大きくなるように４つ以上の送風機の動作を制御してもよい。 Furthermore, in the blower device according to the present disclosure, the control unit may control the operation of four or more blowers so that, in the first blowing mode, the volume of air blown out from the outlet of the first blowing nozzle is greater than the volume of air blown out from the outlet of the second blowing nozzle.
　このようにすることで、さらに、第１送風モードにおいて、第２吹出ノズルから吹き出して形成される気流が第１吹出ノズルから吹き出して形成される気流に引き寄せられるので、気流全体が合わさって直進性の高い気流（面気流）を生成することができる。つまり、利用者に向けて直進性の高い気流を送風することができる。これにより、利用者に、より強く気流を感じさせることができ、快適性を向上させることができる。 Furthermore, by doing this, in the first airflow mode, the airflow formed by blowing out from the second blowing nozzle is attracted to the airflow formed by blowing out from the first blowing nozzle, so that the entire airflow combines to generate a highly straight-line airflow (surface airflow). In other words, a highly straight-line airflow can be blown towards the user. This allows the user to feel a stronger airflow, improving comfort.
　また、本開示に係る送風装置は、利用者の着座部における着座位置を検出する検出部をさらに備え、制御部は、検出部が検出した着座位置の情報に基づいて、第１吹出ノズルおよび第２吹出ノズルを特定してもよい。 The air blowing device according to the present disclosure may further include a detection unit that detects the seating position of the user in the seating area, and the control unit may identify the first and second blowing nozzles based on the information on the seating position detected by the detection unit.
　これにより、さらに、利用者の着座部への着座位置に応じて、第１吹出ノズルおよび第２吹出ノズルとして特定される吹出ノズルを切り替えることができる。つまり、利用者の着座位置によらず、利用者の鉛直方向上方の吹出ノズルを常に第１吹出ノズルとして特定できる。 This also makes it possible to switch between the blow nozzles identified as the first blow nozzle and the second blow nozzle depending on the user's seating position on the seating section. In other words, regardless of the user's seating position, the blow nozzle vertically above the user can always be identified as the first blow nozzle.
　したがって、利用者の着座位置によらず、夏期においては、利用者に直接当たる気流を形成でき、冬期においては、利用者に直接当たらない気流を形成することができる。この結果、利用者が着座部のどの位置に座っても、利用者を居室空間内で快適に過ごさせながら、換気を行うことができる。 Therefore, regardless of the user's seating position, an airflow that hits the user directly can be created in the summer, and an airflow that does not hit the user directly can be created in the winter. As a result, no matter where the user sits in the seating area, ventilation can be performed while allowing the user to stay comfortable in the living space.
　また、本開示に係る送風装置では、制御部は、現在の季節が冬期であることを示す信号を受け付けた場合には、利用者の着座部における着座位置によらず、４つ以上の吹出ノズルのうちの両端に位置する２つの吹出ノズルに向けて、給気口から吸い込まれた空気を送風する第３送風モードに切り替えて４つ以上の送風機の動作を制御するようにしてもよい。 Furthermore, in the blower device according to the present disclosure, when the control unit receives a signal indicating that the current season is winter, the control unit may control the operation of the four or more blowers by switching to a third blowing mode in which air drawn in from the air intake port is blown toward two of the four or more blowing nozzles located at both ends, regardless of the user's seating position in the seating area.
　このようにすることで、さらに、冬期において、居室空間の利用者が意図的に第２送風モードに切り替える手間がなくなり、利用者に気流が当たって寒く感じさせてしまうことが抑制されるので、利用者を居室空間内において快適に過ごさせることができる。 In this way, it is also possible to eliminate the need for users in the living space to intentionally switch to the second airflow mode during winter, and it is possible to prevent users from feeling cold due to the airflow hitting them, allowing them to stay comfortable in the living space.
　以下、本開示の実施の形態について図面を参照しながら説明する。なお、以下の実施の形態は、本開示を具体化した一例であって、本開示の技術的範囲を限定するものではない。 Below, an embodiment of the present disclosure will be described with reference to the drawings.

More specifically, the living space 3a is a main space in the space 3 of the booth 2, and is composed of a floorboard 4, side panels 5 ( side panels 5a, 5b, and 5d), a top board 6, an inner panel 7, and a door 11. The living space 3a has a floor area of, for example, about 1.5 m2 . In addition, in the living space 3a, a desk 12 and a seat 13 are arranged at predetermined positions, as shown in FIG. 1(b).

　中空空間３ｂは、居室空間３ａと連接し、送風装置１の主要構成要素が設置される空間である。より詳細には、中空空間３ｂは、フロアボード４と、サイドパネル５（サイドパネル５ａ、５ｂ、および５ｃ）と、トップボード６と、インナーパネル７とにより構成される。中空空間３ｂは、例えば、０．５ｍ２程度の床面積を有する。詳細は後述するが、中空空間３ｂには、送風装置１の主要構成要素として、複数のチャンバ１８、複数のダクト１９、および複数の送風機２０が所定の位置に配置される。 The hollow space 3b is connected to the living space 3a, and is a space in which the main components of the blower 1 are installed. More specifically, the hollow space 3b is composed of a floorboard 4, side panels 5 ( side panels 5a, 5b, and 5c), a top board 6, and an inner panel 7. The hollow space 3b has a floor area of, for example, about 0.5 m2. As will be described in detail later, a plurality of chambers 18, a plurality of ducts 19, and a plurality of blowers 20 are arranged at predetermined positions in the hollow space 3b as the main components of the blower 1.
　給気口２１は、外部から居室空間３ａ内に空気を供給するための矩形状の開口であり、サイドパネル５ｃのフロアボード４側の位置に設けられる。給気口２１は、後述する送風機２０が動作することにより、ブース２の外部から空気を吸い込む。なお、給気口２１は、矩形であるとしたが、これに限定されず、矩形以外の多角形または円形等であってもよい。 The air intake 21 is a rectangular opening for supplying air from the outside into the living space 3a, and is provided on the floorboard 4 side of the side panel 5c. The air intake 21 draws in air from outside the booth 2 when the blower 20, which will be described later, is operated.

　排気口２２は、居室空間３ａの空気を外部に排出するための矩形状の開口であり、サイドパネル５ｄのフロアボード４側の位置に設けられる。排気口２２は、後述する送風機２０が動作することにより、居室空間３ａから空気を排出する。なお、排気口２２は、矩形であるとしたが、これに限定されず、矩形以外の多角形または円形等であってもよい。 The exhaust port 22 is a rectangular opening for discharging air from the living space 3a to the outside, and is provided on the floorboard 4 side of the side panel 5d. The exhaust port 22 discharges air from the living space 3a when the blower 20, which will be described later, is operated. Note that although the exhaust port 22 has been described as being rectangular, it is not limited to this and may be a polygon other than a rectangle, a circle, or the like.
　なお、ブース２のフロアボード４の下面に図示しないキャスター等の可動部を設けることにより、ブース２を可搬式にしてもよい。また、ブース２が配置される床面と、ブース２のフロアボード４との間に間隙が形成される場合には、給気口２１および排気口２２を、フロアボード４に設けてもよい。 The booth 2 may be made portable by providing movable parts such as casters (not shown) on the underside of the floor board 4 of the booth 2. In addition, if a gap is formed between the floor surface on which the booth 2 is placed and the floor board 4 of the booth 2, the air intake vent 21 and the exhaust vent 22 may be provided in the floor board 4.
　送風装置１は、ブース２における居室空間３ａ内のトップボード６側からフロアボード４側に向かって流れる空気を吹き出し、居室空間３ａ内に下降気流を生成させる装置である。 The blower 1 is a device that blows out air flowing from the top board 6 side to the floor board 4 side in the living space 3a of the booth 2, generating a downward air current within the living space 3a.
　具体的には、送風装置１は、図１の（ｂ）および図２に示すように、複数（本実施の形態では４つ）の吹出ノズル１４（吹出ノズル１４ａ、１４ｂ、１４ｃ、１４ｄ）と、複数の吹出ノズル１４にそれぞれが対応する、複数のチャンバ１８（チャンバ１８ａ、１８ｂ、１８ｃ、１８ｄ）、複数のダクト１９（ダクト１９ａ、１９ｂ、１９ｃ、１９ｄ）、および複数の送風機２０（送風機２０ａ、２０ｂ、２０ｃ、２０ｄ）と、操作パネル４０と、制御部５０と、を有する。 Specifically, as shown in FIG. 1(b) and FIG. 2, the blower device 1 has a plurality of (four in this embodiment) blow nozzles 14 (blow nozzles 14a, 14b, 14c, 14d), a plurality of chambers 18 (chambers 18a, 18b, 18c, 18d), a plurality of ducts 19 (ducts 19a, 19b, 19c, 19d), and a plurality of blowers 20 ( blowers 20a, 20b, 20c, 20d) each corresponding to the plurality of blow nozzles 14, an operation panel 40, and a control unit 50.
　吹出ノズル１４は、送風機２０によって搬送される空気が流入する直方体形状の通風管の一種である。吹出ノズル１４は、吹出ノズル１４の下面に吹出口１５を有する。複数の吹出ノズル１４は、居室空間３ａのトップボード６側の所定の位置に設置され、トップボード６側からフロアボード４側に向かって流れる空気を複数の吹出口１５から吹き出す。 The blow-out nozzle 14 is a type of rectangular parallelepiped ventilation pipe into which air transported by the blower 20 flows. The blow-out nozzle 14 has a blow-out outlet 15 on the underside of the blow-out nozzle 14. The multiple blow-out nozzles 14 are installed at predetermined positions on the top board 6 side of the living space 3a, and blow out the air flowing from the top board 6 side toward the floor board 4 side from the multiple blow-out outlets 15.
　より詳細には、複数の吹出ノズル１４は、図２に示すように、トップボード６から下側にオフセットして配置される。つまり、複数の吹出ノズル１４とトップボード６との間には、所定の空間（後述する負圧領域Ｓ３（図３参照）が生じる空間）が形成される。 More specifically, the multiple blow-out nozzles 14 are positioned offset downward from the top board 6, as shown in FIG. 2. In other words, a predetermined space (a space in which a negative pressure region S3 (see FIG. 3), described below, occurs) is formed between the multiple blow-out nozzles 14 and the top board 6.
　複数の吹出ノズル１４は、図２に示すように、インナーパネル７の上方の位置を起点としてサイドパネル５ｄに向かって水平に延設される。この際、複数の吹出ノズル１４は、起点となるインナーパネル７側において、それぞれ、複数のチャンバ１８と連通接続される。 As shown in FIG. 2, the multiple blow-out nozzles 14 extend horizontally from a position above the inner panel 7 toward the side panel 5d. At this time, the multiple blow-out nozzles 14 are each connected in communication with the multiple chambers 18 on the inner panel 7 side, which is the starting point.
　ここで、「インナーパネル７の上方」とは、起立した人体の頭部よりも高い位置であって、具体的には居室空間３ａにおいてフロアボード４から２００ｃｍ付近の高さの位置以上を示す。また、「水平に延設される」とは、居室空間３ａにおいて床面となるフロアボード４および天井面となるトップボード６に対して平行となる向きに設けられることを示す。 Here, "above the inner panel 7" means a position higher than the head of a standing person, specifically a position at a height of about 200 cm or more above the floorboard 4 in the living space 3a. Also, "extending horizontally" means that it is installed in a direction parallel to the floorboard 4, which forms the floor surface, and the top board 6, which forms the ceiling surface, in the living space 3a.
　４つの吹出ノズル１４（１４ａ、１４ｂ、１４ｃ、１４ｄ）それぞれは、図１の（ｂ）に示すように、その一端から他端がインナーパネル７からサイドパネル５ｄに向けて並列に配置される。このとき、４つの吹出ノズル１４は、図３に示すように、正面視において、互いに等しい間隔ｄを有して並設されている。 As shown in FIG. 1(b), each of the four blowing nozzles 14 (14a, 14b, 14c, 14d) is arranged in parallel from one end to the other end from the inner panel 7 toward the side panel 5d. At this time, the four blowing nozzles 14 are arranged side by side at equal intervals d from each other when viewed from the front, as shown in FIG. 3.
　図３に示すように、複数の吹出ノズル１４の全体は、複数の吹出ノズル１４ａとサイドパネル５ａとの間の間隔Ｄが、吹出ノズル１４ａと吹出ノズル１４ｂとの間の間隔ｄよりも大きくなるように居室空間３ａ内に配置される。また、吹出ノズル１４ｄとサイドパネル５ｂとの間の間隔Ｄについても、吹出ノズル１４ｄと吹出ノズル１４ｃとの間の間隔ｄよりも大きくなるように、複数の吹出ノズル１４が配置される。なお、本実施の形態では、具体的には、間隔Ｄを３９０ｍｍとし、間隔ｄを１４６ｍｍとしているが、間隔Ｄおよび間隔ｄの値はこれらの限りではない。 As shown in FIG. 3, the multiple blow-out nozzles 14 are all arranged in the living space 3a such that the distance D between the multiple blow-out nozzles 14a and the side panel 5a is greater than the distance d between blow-out nozzle 14a and blow-out nozzle 14b. The multiple blow-out nozzles 14 are also arranged such that the distance D between blow-out nozzle 14d and the side panel 5b is also greater than the distance d between blow-out nozzle 14d and blow-out nozzle 14c. In this embodiment, specifically, the distance D is 390 mm and the distance d is 146 mm, but the values of the distances D and d are not limited to these.
　複数の吹出口１５ａ～１５ｄは、それぞれ、複数の吹出ノズル１４ａ～１４ｄの下面に形成されたスリット状の開口である。つまり、複数の吹出口１５は、下方に向けて設けられている。そして、複数の吹出口１５は、それぞれ、複数の吹出ノズル１４に流入した空気を、トップボード６側からフロアボード４に向かって流れる空気を吹き出す。 The multiple air outlets 15a-15d are slit-shaped openings formed on the undersides of the multiple air outlet nozzles 14a-14d, respectively. In other words, the multiple air outlets 15 are provided facing downward. The multiple air outlets 15 each blow out the air that has flowed into the multiple air outlet nozzles 14, and that flows from the top board 6 toward the floor board 4.
　ここで、「下方に向けて」とは、居室空間３ａにおいて、フロアボード４と正対する方向に向かうことを示す。すなわち、吹出口１５は、直方体形状の吹出ノズル１４を形成する面のうち、フロアボード４と正対する面に設けられる。 Here, "downward" refers to the direction facing the floorboard 4 in the living space 3a. In other words, the air outlet 15 is provided on the surface that faces the floorboard 4 among the surfaces that form the rectangular parallelepiped air outlet nozzle 14.
　また、吹出口１５は、矩形状の開口であり、吹出ノズル１４がインナーパネル７から立設する方向が長辺、インナーパネル７の面方向と平行な方向が短辺となるように形成されている。 The air outlet 15 is a rectangular opening, and is formed so that the long side is the direction in which the air outlet nozzle 14 stands upright from the inner panel 7, and the short side is parallel to the surface direction of the inner panel 7.
　吹出口１５は、１つの吹出ノズル１４に対して、１つ設けられる。複数の吹出ノズル１４にそれぞれが属する複数の吹出口１５は、ある水平面を仮想したとき、その水平面上、すなわち同一平面上に配置されている。つまり、居室空間３ａにおいては、複数の吹出ノズル１４にそれぞれが属する複数の吹出口１５は、フロアボード４から同じ高さに配置されている。 One air outlet 15 is provided for each air outlet nozzle 14. When a certain horizontal plane is imagined, the air outlets 15 belonging to each of the multiple air outlet nozzles 14 are arranged on the same horizontal plane. In other words, in the living space 3a, the air outlets 15 belonging to each of the multiple air outlet nozzles 14 are arranged at the same height from the floorboard 4.
　このように、４つの吹出ノズル１４ａ～１４ｄは、４つの吹出口１５ａ～１５ｄが同一平面上に位置するように配置され、また、上述した間隔ｄおよび間隔Ｄを有して並設されることにより、送風面を構成している。そして、４つの吹出ノズル１４は、送風装置１が送風運転を行う際に、操作パネル４０に入力された情報に基づいて、第１吹出ノズル１６と第２吹出ノズル１７とに区別されて送風に用いられる。 In this way, the four blowing nozzles 14a-14d are arranged so that the four blowing outlets 15a-15d are positioned on the same plane, and are arranged side by side with the above-mentioned distances d and D to form an air blowing surface. Then, when the blowing device 1 is operating to blow air, the four blowing nozzles 14 are distinguished into a first blowing nozzle 16 and a second blowing nozzle 17 and used for blowing air based on information input to the operation panel 40.
　詳細は図４～図７を参照して後述するが、第１吹出ノズル１６は、４つの吹出ノズル１４のうち、利用者１００の鉛直方向上方に位置する１または複数の吹出ノズル１４である。第１吹出ノズル１６は、操作パネル４０で入力された、利用者１００の着座部１３上の着座位置から特定される。 Details will be described later with reference to Figures 4 to 7, but the first blowing nozzle 16 is one or more of the four blowing nozzles 14 that are located vertically above the user 100. The first blowing nozzle 16 is identified from the seating position of the user 100 on the seating section 13, which is input via the operation panel 40.
　一方、第２吹出ノズル１７は、４つの吹出ノズル１４のうち、第１吹出ノズル１６以外の１または複数の吹出ノズル１４である。つまり、第２吹出ノズル１７は、４つの吹出ノズル１４のうち、利用者１００の鉛直方向上方に位置していない吹出ノズル１４である、ともいえる。 On the other hand, the second blow-out nozzle 17 is one or more of the four blow-out nozzles 14 other than the first blow-out nozzle 16. In other words, the second blow-out nozzle 17 can be said to be a blow-out nozzle 14 that is not positioned vertically above the user 100 among the four blow-out nozzles 14.
　チャンバ１８は、吹出ノズル１４とダクト１９とを連通接続する筐体である。チャンバ１８は、吹出ノズル１４へ向かう空気の流れ（気流の向き）を制御する。 The chamber 18 is a housing that connects the blow-out nozzle 14 and the duct 19. The chamber 18 controls the air flow (airflow direction) toward the blow-out nozzle 14.
　より詳細には、チャンバ１８の側面に吹出ノズル１４が接続され、チャンバ１８の下面にダクト１９が接続される。チャンバ１８は、ダクト１９から流入した空気の流れる方向を、吹出ノズル１４へ向かう方向とするように制御する。 More specifically, the blow-out nozzle 14 is connected to the side of the chamber 18, and the duct 19 is connected to the bottom of the chamber 18. The chamber 18 controls the flow direction of the air flowing in from the duct 19 so that it is directed toward the blow-out nozzle 14.
　１つの吹出ノズル１４に対して１つのチャンバ１８が接続される。すなわち、複数のチャンバ１８として、吹出ノズル１４と同数の４つのチャンバ１８が配置される。チャンバ１８は、インナーパネル７の上方の位置に配置される。なお、チャンバ１８は、吹出ノズル１４とダクト１９とを連通接続できれば、特に形状は限定されない。 One chamber 18 is connected to one blow-out nozzle 14. In other words, four chambers 18 are arranged, the same number as the blow-out nozzles 14. The chambers 18 are arranged above the inner panel 7. The shape of the chambers 18 is not particularly limited, as long as it can connect the blow-out nozzles 14 and the duct 19 in communication.
　ダクト１９は、給気口２１から送風機２０に吸い込まれた空気を、チャンバ１８へ搬送するための通風管である。ダクト１９は、一端がチャンバ１８に接続し、他端が送風機２０に接続する。１つのチャンバ１８に対して１つのダクト１９が配置される。すなわち、図２の例においては、複数のダクト１９として、４つのダクト１９が配置される。ダクト１９としては、例えば公知のフレキシブルダクトを採用することが可能である。 The duct 19 is an air duct for transporting air drawn into the blower 20 from the air intake 21 to the chamber 18. One end of the duct 19 is connected to the chamber 18, and the other end is connected to the blower 20. One duct 19 is arranged for one chamber 18. That is, in the example of FIG. 2, four ducts 19 are arranged as the multiple ducts 19. As the duct 19, for example, a known flexible duct can be used.
　送風機２０は、給気口２１からダクト１９およびチャンバ１８を介して吹出ノズル１４の吹出口１５へ向かう気流を生成する機器である。送風機２０としては、例えば、遠心送風機等の公知のターボ機械を採用することが可能である。 The blower 20 is a device that generates an airflow that flows from the air intake 21 through the duct 19 and the chamber 18 toward the outlet 15 of the blowing nozzle 14. As the blower 20, for example, a known turbo machine such as a centrifugal blower can be used.
　１つの吹出ノズル１４に対して１つの送風機２０が接続される。すなわち、送風機２０は、吹出ノズル１４と同数が配置される。図２の例では、複数の送風機２０は、図１の（ｂ）に示すように、吹出ノズル１４ａに空気を送風する送風機２０ａと、吹出ノズル１４ｂに空気を送風する送風機２０ｂと、吹出ノズル１４ｃに空気を送風する送風機２０ｃと、吹出ノズル１４ｄに空気を送風する送風機２０ｄとを有する。送風機２０は、給気口２１から吹出ノズル１４へ向かう空気の流れを生じさせ、給気口２１から吸い込んだ空気を、ダクト１９およびチャンバ１８を介して吹出ノズル１４に供給する。 One blower 20 is connected to one blowing nozzle 14. That is, the same number of blowers 20 are arranged as the blowing nozzles 14. In the example of FIG. 2, the blowers 20 include blower 20a that blows air to blowing nozzle 14a, blower 20b that blows air to blowing nozzle 14b, blower 20c that blows air to blowing nozzle 14c, and blower 20d that blows air to blowing nozzle 14d, as shown in FIG. 1(b). The blower 20 generates an air flow from the air inlet 21 toward the blowing nozzle 14, and supplies the air sucked from the air inlet 21 to the blowing nozzle 14 via the duct 19 and the chamber 18.
　ここで、複数の送風機２０（送風機２０ａ、２０ｂ、２０ｃ、２０ｄ）それぞれは、風量（空気供給量）を調整できる機構を備えている。詳細は後述するが、本実施の形態では、第１送風モードにおいて、４つの送風機２０は、４つの送風機２０のうち、第１吹出ノズル１６に連通する送風機２０の送風量が、第２吹出ノズル１７に連通する送風機２０の送風量よりも大きくなるように制御される。 Here, each of the multiple blowers 20 ( blowers 20a, 20b, 20c, 20d) has a mechanism that can adjust the air volume (air supply volume). Details will be described later, but in this embodiment, in the first air blowing mode, the four blowers 20 are controlled so that the air volume of the blower 20 communicating with the first blowing nozzle 16 is greater than the air volume of the blower 20 communicating with the second blowing nozzle 17.
　操作パネル４０は、ブース２の利用者１００が、送風装置１における送風モード（後述する第１送風モードまたは第２送風モード）を選択するためのコントローラである。操作パネル４０は、例えば、スイッチまたはタッチパネル等である。 The operation panel 40 is a controller that allows the user 100 of the booth 2 to select the air blowing mode (the first air blowing mode or the second air blowing mode described below) of the air blowing device 1. The operation panel 40 is, for example, a switch or a touch panel.
　利用者１００は、操作パネル４０を用いて、着座部１３に利用者１００が着座する位置も入力設定する。 The user 100 also uses the operation panel 40 to input and set the position where the user 100 will be seated on the seating section 13.
　操作パネル４０は、ブース２の居室空間３ａに設置されるが、ブース２の外壁等、ブース２の近傍に設置してもよい。なお、操作パネル４０は、ネットワークを利用して外部から操作する端末等であってもよい。 The operation panel 40 is installed in the living space 3a of the booth 2, but may also be installed near the booth 2, such as on the outer wall of the booth 2. The operation panel 40 may also be a terminal that is operated from outside using a network.
　制御部５０は、操作パネル４０からの入力信号を受け付け、複数の送風機２０に送風の指示を送るための制御装置である。制御部５０は、ハードウェアまたはソフトウェアのいずれで構成してもよい。制御部５０をソフトウェアとして構成する場合には、制御部５０はコンピュータ（プロセッサ）と記憶部（メモリ）とを有し、記憶部に記憶されたプログラムをコンピュータにより実行することによって後述する制御が実現される構成であってもよい。 The control unit 50 is a control device that receives input signals from the operation panel 40 and sends instructions to blow air to the multiple fans 20. The control unit 50 may be configured as either hardware or software. When the control unit 50 is configured as software, the control unit 50 may have a computer (processor) and a storage unit (memory), and may be configured to realize the control described below by having the computer execute a program stored in the storage unit.
　制御部５０は、図２に示すように、着座部１３の内部に配置されてもよく、利用者１００の動線を阻害する場所でなければ、配置はこの限りではない。 The control unit 50 may be placed inside the seating area 13 as shown in FIG. 2, but the placement is not limited to this as long as it is not in a location that obstructs the movement of the user 100.
　以上のように、送風装置１は構成される。 The blower device 1 is configured as described above.
　なお、送風装置１は、給気口２１から複数の吹出ノズル１４の複数の吹出口１５に向かって吹き出される気流が通過する各風路上に、ブース２外の空気に含まれる塵埃等を捕集するためのフィルタを備えてもよい。これにより、フィルタを通過する前に比べて塵埃等の異物が含まれる量が少ない空気を居室空間３ａへ供給することができる。 The blower device 1 may also be provided with a filter for collecting dust and other particles contained in the air outside the booth 2 on each air passage through which the airflow blown out from the air inlet 21 toward the multiple air outlets 15 of the multiple air outlet nozzles 14 passes. This makes it possible to supply air containing less dust and other foreign matter to the living space 3a compared to air before it passed through the filter.
　送風装置１がフィルタを備える場合には、送風機２０は、フィルタに対して下流側に配置されることが好ましい。これにより、送風機２０に塵埃等の異物が堆積することを抑制することができる。よって、送風機２０において、堆積した塵埃等の異物と水分とによりトラッキング現象が発生する可能性を低減することができる。 If the blower device 1 is equipped with a filter, it is preferable that the blower 20 is disposed downstream of the filter. This makes it possible to prevent foreign matter such as dust from accumulating on the blower 20. This makes it possible to reduce the possibility of a tracking phenomenon occurring in the blower 20 due to accumulated foreign matter such as dust and moisture.
　［２．送風運転］
　次に、送風装置１が行う送風運転について説明する。 [2. Fan operation]
Next, the blowing operation performed by the blower 1 will be described.
　送風装置１は、居室空間３ａの内部空間を常に換気し、居室空間３ａ内での二酸化炭素濃度の上昇を防ぐための装置である。 The blower 1 is a device that constantly ventilates the interior space of the living space 3a and prevents an increase in the carbon dioxide concentration within the living space 3a.
　まず、居室空間３ａでの二酸化炭素濃度の上昇について説明する。ブース２は個人が利用する、囲まれた狭小空間である。そのため、ブース２内の空気の入れ替えを意図的に行わないと、居室空間３ａの空気が滞留する。したがって、居室空間３ａ内に利用者１００が滞在すると、利用者１００自身の呼吸によって、居室空間３ａ内の二酸化炭素濃度が上昇して建築物衛生環境管理基準に定められた基準値を超え、空気汚染が起きてしまう可能性がある。 First, we will explain the increase in carbon dioxide concentration in the living space 3a. The booth 2 is a small, enclosed space used by an individual. Therefore, unless the air in the booth 2 is intentionally replaced, the air in the living space 3a will stagnate. Therefore, when a user 100 stays in the living space 3a, the user's 100's own breathing will increase the carbon dioxide concentration in the living space 3a, causing it to exceed the standard value set out in the Building Sanitation Environment Management Standards, which could result in air pollution.
　そこで、送風装置１によって、居室空間３ａの内部空間へ外部空間から送風を行い、空気を入れ替えることにより、居室空間３ａ内の二酸化炭素濃度の上昇を防ぎ、利用者１００が快適に過ごせるようにする。送風装置１が送風機２０を作動させることによって、居室空間３ａの外部空間から居室空間３ａの内部空間へと空気が給気され、居室空間３ａ内の空気が押し出されて排気されるので、居室空間３ａ内の換気を行うことができる。なお、具体的には、居室空間３ａ内の二酸化炭素濃度が、基準値未満（例えば、居室空間３ａ内の二酸化炭素の濃度が１０００ｐｐｍ未満）となることが望ましい。 Then, the blower 1 blows air from the external space into the internal space of the living space 3a, replacing the air and preventing an increase in the carbon dioxide concentration in the living space 3a, allowing the user 100 to stay in comfort. When the blower 1 operates the blower 20, air is supplied from the external space of the living space 3a to the internal space of the living space 3a, and the air in the living space 3a is pushed out and exhausted, thereby ventilating the living space 3a. Specifically, it is desirable for the carbon dioxide concentration in the living space 3a to be less than the standard value (for example, the carbon dioxide concentration in the living space 3a is less than 1000 ppm).
　次に、送風装置１の送風モードについて説明する。送風装置１は、居室空間３ａ内の快適性を保ちながら換気をするために、制御部５０によって、第１送風モードと第２送風モードとを切り替えて送風運転を行う。 Next, the air blowing modes of the air blower 1 will be described. In order to ventilate while maintaining comfort within the living space 3a, the air blower 1 performs air blowing operation by switching between the first air blowing mode and the second air blowing mode via the control unit 50.
　第１送風モードは、送風機２０が、第１吹出ノズル１６および第２吹出ノズル１７へ送風を行う送風運転のモードである。つまり、第１送風モードは、４つの吹出ノズル１４の全体を使って送風するモードであり、面気流モードともいえる。本実施の形態では、居室空間３ａにおいて、直進性の高い気流（面気流）が送風されるように、第１吹出ノズル１６からの送風量が第２吹出ノズル１７からの送風量よりも多くなるように送風運転を行うように、４つの送風機２０を制御している。 The first blowing mode is a blowing operation mode in which the blower 20 blows air to the first blowing nozzle 16 and the second blowing nozzle 17. In other words, the first blowing mode is a mode in which air is blown using all four blowing nozzles 14, and can also be called a surface airflow mode. In this embodiment, the four blowers 20 are controlled to perform blowing operation such that the amount of air blown from the first blowing nozzle 16 is greater than the amount of air blown from the second blowing nozzle 17, so that a highly linear airflow (surface airflow) is blown in the living space 3a.
　第２送風モードは、第１吹出ノズル１６への送風は行わず、第２吹出ノズル１７のみに選択的に送風を行う送風運転のモードである。つまり、第２送風モードは、４つの吹出ノズル１４のうちの一部の吹出ノズル１４を使って送風するモードであり、部分気流モードともいえる。 The second airflow mode is an airflow operation mode in which air is not blown to the first blowing nozzle 16, but is selectively blown to only the second blowing nozzle 17. In other words, the second airflow mode is a mode in which air is blown using some of the four blowing nozzles 14, and can also be called a partial airflow mode.
　第１送風モードおよび第２送風モードでの風量の概略について説明する。 An overview of the air volume in the first and second air flow modes is given below.
　第１送風モードおよび第２送風モードにおいて、送風機２０が送風する風量の下限値は、居室空間３ａ内の二酸化炭素濃度が基準値（例えば二酸化炭素濃度が１０００ｐｐｍ）未満に保たれる風量に設定されている。 In the first and second airflow modes, the lower limit of the airflow volume blown by the blower 20 is set to an airflow volume that keeps the carbon dioxide concentration in the living space 3a below a reference value (e.g., a carbon dioxide concentration of 1000 ppm).
　第１送風モードと第２送風モードとでは、季節別の使い分けを想定して、居室空間３ａの利用者１００に当たる空気の流れ方と風速とを決定している。例えば、第１送風モードでは、主に夏期と中間期間（春期、秋期）の利用を想定し、一方で、第２送風モードでは、主に冬期の利用を想定している。利用者１００に当たる空気の流れ方については後述する。 The first and second airflow modes determine the flow and speed of the air that hits the user 100 in the living space 3a, assuming different seasonal use. For example, the first airflow mode is intended for use mainly in the summer and intermediate periods (spring and autumn), while the second airflow mode is intended for use mainly in the winter. The flow of the air that hits the user 100 will be described later.
　第１送風モードにおいては、利用者１００が着座部１３で座って作業する姿勢をした際に、利用者１００周辺の風速が、気流感（気流が肌表面を流れる感覚）を感じる閾値である風速０．４ｍ／ｓ以上（例えば０．４ｍ／ｓ～０．７ｍ／ｓ）となるように、送風装置１が送風運転を行う。具体的には、送風装置１では、第１送風モードにおいて、送風機２０ａ、送風機２０ｂ、送風機２０ｃ、および送風機２０ｄの合計送風量が約１４０ｍ３／ｈ以上になるように設定される。 In the first air blowing mode, when the user 100 is in a sitting position to work on the seat 13, the air blower 1 operates to blow air so that the wind speed around the user 100 is equal to or higher than 0.4 m/s (e.g., 0.4 m/s to 0.7 m/s), which is the threshold for feeling airflow (the sensation of airflow flowing over the skin surface). Specifically, in the first air blowing mode, the air blower 1 is set so that the total airflow volume of the air blowers 20a, 20b, 20c, and 20d is equal to or higher than about 140 m3 /h.
　第２送風モードにおいては、利用者１００が着座部１３で座って作業する姿勢をした際に、利用者１００周辺の風速が、気流感（気流が肌表面を流れる感覚）を感じる閾値である風速０．４ｍ／ｓ未満（例えば０．２ｍ／ｓ）となるように、送風装置１が送風運転を行う。具体的には、送風装置１では、第２送風モードにおいて、送風機２０ａ、送風機２０ｂ、送風機２０ｃ、および送風機２０ｄのうち、第２吹出ノズル１７として特定された１または複数の吹出ノズル１４の送風する送風機２０の合計送風量が約８０ｍ３／ｈ以下となるように設定される。 In the second air blowing mode, when the user 100 is in a sitting position on the seat 13, the air blower 1 blows air so that the wind speed around the user 100 is less than 0.4 m/s (e.g., 0.2 m/s), which is the threshold for feeling airflow (the sensation of airflow flowing over the skin surface). Specifically, in the second air blowing mode, the air blower 1 is set so that the total air volume of the air blown by the one or more blowing nozzles 14 specified as the second blowing nozzle 17 among the blowers 20a, 20b, 20c, and 20d is approximately 80 m3 /h or less.
　［３．全体的な気流の説明］
　次に、送風装置１で生成される主要な気流の全体の流れについて、利用者１００がブース中央に着座した状態で、第１送風モードにより送風する場合を例に挙げて、図２～図４を参照しながら説明する。 [3. Description of overall airflow]
Next, the overall flow of the main air current generated by the blower device 1 will be explained with reference to Figures 2 to 4, using as an example the case where air is blown in the first blowing mode while the user 100 is seated in the center of the booth.
　図４は、ブース中央に着座する利用者１００に対して、送風装置１の第１送風モードにおいて生成される気流の流れを示す正面図である。 Figure 4 is a front view showing the airflow generated by the blower 1 in the first blowing mode for a user 100 seated in the center of the booth.
　図２に示すように、送風機２０の運転動作が開始されると、ブース２外の空気が、気流ＡＦ１２となって給気口２１から吸い込まれる。給気口２１から吸い込まれた空気（気流ＡＦ１２）は、ダクト１９の内部を気流ＡＦ１３として流通して、チャンバ１８へ搬送される。 As shown in FIG. 2, when the blower 20 starts operating, air outside the booth 2 becomes airflow AF12 and is sucked in through the air intake 21. The air sucked in through the air intake 21 (airflow AF12) flows inside the duct 19 as airflow AF13 and is transported to the chamber 18.
　チャンバ１８へ搬送された空気（気流ＡＦ１３）では、チャンバ１８によって、気流ＡＦ１３の進行方向が鉛直上方向（フロアボード４側からトップボード６側へ向かう方向）から水平方向（サイドパネル５ｃ側からサイドパネル５ｄ側へ向かう方向）へと切り換えられる。つまり、チャンバ１８へ搬送された空気は、吹出ノズル１４へ向かう空気の流れとして制御され、気流ＡＦ１４として吹出ノズル１４の内部を流通する。 The air (airflow AF13) transported to chamber 18 is switched by chamber 18 from a vertically upward direction (from floor board 4 to top board 6) to a horizontal direction (from side panel 5c to side panel 5d). In other words, the air transported to chamber 18 is controlled as an air flow toward blow-out nozzle 14, and flows through the inside of blow-out nozzle 14 as airflow AF14.
　そして、吹出ノズル１４へ流入した空気（気流ＡＦ１４）は、気流ＡＦ１５として吹出口１５から下方に向けて、すなわちフロアボード４に向けて吹き出される。 Then, the air (airflow AF14) that flows into the blow-out nozzle 14 is blown out as airflow AF15 from the blow-out port 15 downward, i.e., toward the floorboard 4.
　吹出口１５から吹き出された空気（気流ＡＦ１５）は、気流ＡＦ３１として居室空間３ａ内をフロアボード４に向かって流通していく。 The air (airflow AF15) blown out from the air outlet 15 flows as airflow AF31 through the living space 3a toward the floorboard 4.
　より詳細には、図４に示すように、送風装置１が第１送風モードで運転を行うと、複数の送風機２０は、第１吹出ノズル１６および第２吹出ノズル１７へ空気を搬送する。なお、本例では、４つの吹出ノズル１４ａ～１４ｄのうち、利用者１００の上方に位置する吹出ノズル１４ｂ、１４ｃが第１吹出ノズルを構成し、それ以外の吹出ノズル１４ａ、１４ｄが第２吹出ノズル１７を構成する。 More specifically, as shown in FIG. 4, when the blower device 1 operates in the first blowing mode, the multiple blowers 20 transport air to the first blowing nozzle 16 and the second blowing nozzle 17. In this example, of the four blowing nozzles 14a to 14d, the blowing nozzles 14b and 14c located above the user 100 constitute the first blowing nozzle, and the remaining blowing nozzles 14a and 14d constitute the second blowing nozzle 17.
　これにより、第１吹出ノズル１６の吹出口１５から気流ＡＦ１５ｂが生成され、第２吹出ノズル１７の吹出口１５から気流ＡＦ１５ａが生成される。生成された気流ＡＦ１５ｂと気流ＡＦ１５ａとは、合流して気流ＡＦ３１として居室空間３ａ内をフロアボード４に向かって流通していく。 As a result, an airflow AF15b is generated from the outlet 15 of the first blowing nozzle 16, and an airflow AF15a is generated from the outlet 15 of the second blowing nozzle 17. The generated airflows AF15b and AF15a join together to form airflow AF31, which circulates through the living space 3a toward the floorboard 4.
　なお、第１送風モードにおいては、第１吹出ノズル１６から吹き出す風量が、第２吹出ノズル１７から吹き出す風量よりも多くなるように制御されているので、利用者１００に向かって流れる気流ＡＦ３１は、直進性の高い気流（面気流）としてフロアボード４に向かって流通していく。直進性の高い気流については、後述する。 In the first airflow mode, the amount of air blown out from the first blowing nozzle 16 is controlled to be greater than the amount of air blown out from the second blowing nozzle 17, so the airflow AF31 flowing toward the user 100 flows toward the floorboard 4 as a highly linear airflow (surface airflow). The highly linear airflow will be described later.
　その後、図２に示すように、フロアボード４に到達した空気（気流ＡＦ３１）の一部は、気流ＡＦ３１ａとして排気口２２からブース２外に排気される。また、図４に示すように、フロアボード４に到達した空気（気流ＡＦ３１）の他の部分は、フロアボード４によって反射されて気流ＡＦ３１ｂとなり、サイドパネル５（サイドパネル５ａおよびサイドパネル５ｂ）に沿ってトップボード６に向かう還流気流である気流ＡＦ４１として流れる。 Then, as shown in FIG. 2, part of the air (airflow AF31) that has reached the floorboard 4 is exhausted to the outside of the booth 2 from the exhaust port 22 as airflow AF31a. Also, as shown in FIG. 4, the other part of the air (airflow AF31) that has reached the floorboard 4 is reflected by the floorboard 4 to become airflow AF31b, and flows as airflow AF41, which is a return airflow that flows along the side panel 5 (side panel 5a and side panel 5b) toward the top board 6.
　さらに、机１２の上面に到達した空気（気流ＡＦ３１）の一部もまた、机１２の上面によって反射されて気流ＡＦ３１ｃとなる。気流ＡＦ３１ｃは、サイドパネル５（サイドパネル５ａおよびサイドパネル５ｂ）に沿ってトップボード６に向かう上昇気流（以下、還流気流ともいう）である気流ＡＦ４１の一部として流れる。 Furthermore, a portion of the air (airflow AF31) that reaches the top surface of the desk 12 is also reflected by the top surface of the desk 12 to become airflow AF31c. Airflow AF31c flows as part of airflow AF41, which is an ascending airflow (hereinafter also referred to as a return airflow) that flows along the side panel 5 (side panel 5a and side panel 5b) toward the top board 6.
　本実施の形態では、居室空間３ａの中央領域において気流ＡＦ３１が下降気流となって流通する一方で、居室空間３ａの端部領域において気流ＡＦ４１が還流気流となって流通する。つまり、居室空間３ａの端部領域には、サイドパネル５（サイドパネル５ａおよびサイドパネル５ｂ）の表面近傍に沿って気流ＡＦ４１が流通する「還流風路」が形成される。 In this embodiment, the airflow AF31 circulates as a downward airflow in the central region of the living space 3a, while the airflow AF41 circulates as a return airflow in the end region of the living space 3a. In other words, in the end region of the living space 3a, a "return air passage" is formed in which the airflow AF41 circulates along the vicinity of the surface of the side panel 5 (side panel 5a and side panel 5b).
　［４．第１送風モードで生成する直進性の高い気流］
　次に、図３を参照して、送風装置１が第１送風モードで形成する直進性の高い気流（面気流）である気流ＡＦ３１について詳細に説明する。なお、以下の説明において、各送風機２０で設定される具体的な送風量は、あくまでも一例であり、本開示はこれに限定されない。 [4. Highly linear airflow generated in the first airflow mode]
Next, the airflow AF31, which is a highly linear airflow (surface airflow) formed by the blower device 1 in the first blowing mode, will be described in detail with reference to Fig. 3. Note that in the following description, the specific airflow rates set by each blower 20 are merely examples, and the present disclosure is not limited thereto.
　第１送風モードでは、第１吹出ノズル１６および第２吹出ノズル１７へ空気をそれぞれ搬送するように、複数の送風機２０が作動する。より詳細には、送風装置１の運転動作が開始されると、複数の送風機２０ａ～２０ｄのうち、第１吹出ノズル１６（吹出ノズル１４ｂ、１４ｃ）へ送風を行う送風機２０（送風機２０ｂおよび送風機２０ｃ）は、いずれも送風量１００ｍ３／ｈで作動し、第２吹出ノズル１７（吹出ノズル１４ａ、１４ｄ）へ送風を行う送風機２０（送風機２０ａおよび送風機２０ｄ）は、いずれも送風量５０ｍ３／ｈで作動するように制御される。 In the first blowing mode, the multiple fans 20 operate to transport air to the first blowing nozzle 16 and the second blowing nozzle 17. More specifically, when the operation of the blower device 1 is started, among the multiple fans 20a to 20d, the fans 20 (fan 20b and fan 20c) that blow air to the first blowing nozzle 16 ( blowout nozzles 14b and 14c) are all controlled to operate at an air volume of 100 m 3 /h, and the fans 20 (fan 20a and fan 20d) that blow air to the second blowing nozzle 17 ( blowout nozzles 14a and 14d) are all controlled to operate at an air volume of 50 m 3 /h.
　図３に示すように、送風機２０ａおよび送風機２０ｄが作動すると、給気口２１からブース２外の空気が吸い込まれ、吹出ノズル１４ａの吹出口１５ａおよび吹出ノズル１４ｄの吹出口１５ｄそれぞれから気流ＡＦ１５ａが吹き出される。一方、送風機２０ｂおよび送風機２０ｃが作動すると、給気口２１からブース２外の空気が吸い込まれ、吹出ノズル１４ｂの吹出口１５ｂおよび吹出ノズル１４ｃの吹出口１５ｃそれぞれから気流ＡＦ１５ｂが吹き出される。 As shown in FIG. 3, when blowers 20a and 20d are operated, air outside the booth 2 is sucked in through the air inlet 21, and airflow AF15a is blown out from outlet 15a of blow nozzle 14a and outlet 15d of blow nozzle 14d. On the other hand, when blowers 20b and 20c are operated, air outside the booth 2 is sucked in through the air inlet 21, and airflow AF15b is blown out from outlet 15b of blow nozzle 14b and outlet 15c of blow nozzle 14c.
　ここで、２つの気流ＡＦ１５ａの風量は、それぞれ、送風機２０ａおよび送風機２０ｄの送風量に対応して約５０ｍ３／ｈとなり、２つの気流ＡＦ１５ｂの風量は、それぞれ、送風機２０ｂおよび送風機２０ｃの送風量に対応して約１００ｍ３／ｈとなっている。つまり、気流ＡＦ１５の全体としては、合計風量が約３００ｍ３／ｈとなっている。 Here, the air volume of the two airflows AF15a is about 50 m3 /h corresponding to the air volume of the blower 20a and the blower 20d, respectively, and the air volume of the two airflows AF15b is about 100 m3 /h corresponding to the air volume of the blower 20b and the blower 20c, respectively. In other words, the total air volume of the airflow AF15 as a whole is about 300 m3 /h.
　気流ＡＦ１５ａおよび気流ＡＦ１５ｂが居室空間３ａに吹き出されると、気流ＡＦ１５ａおよび気流ＡＦ１５ｂの周囲の空間の空気が気流ＡＦ１５ａおよび気流ＡＦ１５ｂに引き寄せられ、吹き出される風量に応じて、隣り合う４つの吹出ノズル１４の間の３つの空間に、２つの負圧領域Ｓ１および１つの負圧領域Ｓ２が生成される。 When the airflows AF15a and AF15b are blown out into the living space 3a, the air in the space around the airflows AF15a and AF15b is attracted to the airflows AF15a and AF15b, and two negative pressure areas S1 and one negative pressure area S2 are generated in the three spaces between the four adjacent blow-out nozzles 14 depending on the volume of air blown out.
　より詳細には、吹出ノズル１４ａと吹出ノズル１４ｂとの間の空間に負圧領域Ｓ１が生成され、吹出ノズル１４ｂと吹出ノズル１４ｃとの間の空間に負圧領域Ｓ２が生成され、吹出ノズル１４ｃと吹出ノズル１４ｄとの間の空間に負圧領域Ｓ１が生成される。 More specifically, a negative pressure region S1 is generated in the space between blow nozzle 14a and blow nozzle 14b, a negative pressure region S2 is generated in the space between blow nozzle 14b and blow nozzle 14c, and a negative pressure region S1 is generated in the space between blow nozzle 14c and blow nozzle 14d.
　ここで、負圧（陰圧とも呼ぶ）とは、周囲に比べて気圧が低い状態のことを指す。つまり、負圧領域Ｓ１および負圧領域Ｓ２は、周囲の気圧に比べて気圧の低い領域である。 Here, negative pressure (also called negative pressure) refers to a state in which the air pressure is lower than the surrounding air pressure. In other words, negative pressure area S1 and negative pressure area S2 are areas where the air pressure is lower than the surrounding air pressure.
　負圧領域Ｓ１および負圧領域Ｓ２が生成されると、負圧を解消しようとする力が働き、複数の吹出ノズル１４の周囲の空間から負圧領域Ｓ１および負圧領域Ｓ２を解消するための空気の流れ（気流ＡＦ２１ａおよび気流ＡＦ２１ｂ）が生成される。 When negative pressure areas S1 and S2 are generated, a force acts to eliminate the negative pressure, and air flows (airflows AF21a and AF21b) are generated in the space around the multiple blow-out nozzles 14 to eliminate negative pressure areas S1 and S2.
　より詳細には、負圧領域Ｓ１に起因して生じる空気の流れが気流ＡＦ２１ａであり、負圧領域Ｓ２に起因して生じる空気の流れが気流ＡＦ２１ｂである。気流ＡＦ２１ａおよび気流ＡＦ２１ｂは、誘引気流とも呼ばれる。また、気流ＡＦ２１ａまたは気流ＡＦ２１ｂが流れる複数の吹出ノズル１４間の空間は、誘引風路とも呼ばれる。 More specifically, the air flow caused by the negative pressure region S1 is airflow AF21a, and the air flow caused by the negative pressure region S2 is airflow AF21b. Airflow AF21a and airflow AF21b are also called induced airflows. The space between the multiple blowing nozzles 14 through which airflow AF21a or airflow AF21b flows is also called an induced air duct.
　また、居室空間３ａのような限られた（狭小な）空間においては、気流ＡＦ２１ａおよび気流ＡＦ２１ｂの周囲の空間（誘引風路の流入口近傍の空間）の空気が気流ＡＦ２１ａおよび気流ＡＦ２１ｂによって引き寄せられるので、複数の吹出ノズル１４とトップボード６との間の空間に負圧領域Ｓ３が生成される。 Furthermore, in a limited (narrow) space such as the living space 3a, the air in the space around the airflows AF21a and AF21b (the space near the inlet of the induction air duct) is drawn in by the airflows AF21a and AF21b, generating a negative pressure area S3 in the space between the multiple blow-out nozzles 14 and the top board 6.
　これにより、負圧領域Ｓ３を解消するための空気の流れ（気流ＡＦ４１）が生成される。つまり、負圧領域Ｓ３を介して誘引風路に誘引される空気を導入する経路となる還流経路が形成され、誘引風路に空気が誘引されるようになる。 This creates an air flow (air flow AF41) to eliminate the negative pressure area S3. In other words, a return path is formed that serves as a path for introducing air that is induced into the induced air duct via the negative pressure area S3, and the air is then induced into the induced air duct.
　なお、気流ＡＦ１５ａと気流ＡＦ１５ｂとの風量の関係は、気流ＡＦ１５ｂ＞気流ＡＦ１５ａであるため、負圧の大きさは負圧領域Ｓ２＞負圧領域Ｓ１となる。このため、気流ＡＦ２１ａと気流ＡＦ２１ｂとの風量の関係は、気流ＡＦ２１ｂ＞気流ＡＦ２１ａとなる。 Note that the relationship in air volume between airflow AF15a and airflow AF15b is airflow AF15b > airflow AF15a, so the magnitude of the negative pressure is negative pressure area S2 > negative pressure area S1. Therefore, the relationship in air volume between airflow AF21a and airflow AF21b is airflow AF21b > airflow AF21a.
　気流ＡＦ１５ａおよび気流ＡＦ１５ｂ、ならびに、気流ＡＦ２１ａおよび気流ＡＦ２１ｂは、居室空間３ａにおいて気流全体が合わさって、直進性の高い気流（面気流）である気流ＡＦ３１となる。 Airflows AF15a and AF15b, as well as airflows AF21a and AF21b, combine in the living space 3a to become airflow AF31, which is a highly linear airflow (surface airflow).
　一方、気流ＡＦ４１は、複数の吹出ノズル１４とトップボード６との間の空間に向かう空気であるが、気流ＡＦ１５ａおよび気流ＡＦ１５ｂ、ならびに、気流ＡＦ２１ａおよび気流ＡＦ２１ｂとは気流の流れる方向が異なり、フロアボード４側からトップボード６に向かう方向の気流（還流気流）となる。このため、気流ＡＦ４１は、気流ＡＦ４１と隣接する気流ＡＦ１５ａの流れを乱し、気流の直進性を妨げる要因となり得る。 On the other hand, airflow AF41 is air flowing toward the space between the multiple blow-out nozzles 14 and the top board 6, but the direction of the airflow differs from that of airflow AF15a and airflow AF15b, and from that of airflow AF21a and airflow AF21b, and is an airflow (return airflow) flowing from the floor board 4 toward the top board 6. For this reason, airflow AF41 disturbs the flow of airflow AF15a adjacent to airflow AF41, and can be a factor in preventing the straightness of the airflow.
　しかしながら、本実施の形態では、気流ＡＦ１５ａおよび気流ＡＦ１５ｂの風量関係が「気流ＡＦ１５ｂ＞気流ＡＦ１５ａ」であるため、気流ＡＦ１５ａは、気流ＡＦ１５ａに隣接する気流ＡＦ１５ｂに引き寄せられる。これにより、気流ＡＦ１５ａは、気流ＡＦ４１の影響を受けにくくなるので、気流ＡＦ３１は、気流全体として吹出方向に直線的な気流である面気流を維持することができる。 However, in this embodiment, the air volume relationship between airflow AF15a and airflow AF15b is "airflow AF15b > airflow AF15a", so airflow AF15a is attracted to airflow AF15b adjacent to airflow AF15a. As a result, airflow AF15a is less susceptible to the influence of airflow AF41, so airflow AF31 can maintain a planar airflow that is a linear airflow in the blowing direction as a whole.
　以上のようにして、送風装置１は、第１送風モードにおいて、第１吹出ノズル１６および第２吹出ノズル１７の両方へ送風を行うことによって、居室空間３ａ内で利用者１００に向かって直進性の高い気流（面気流）を形成することができる。 In this way, in the first air blowing mode, the air blower 1 blows air from both the first blowing nozzle 16 and the second blowing nozzle 17, thereby forming a highly linear airflow (surface airflow) toward the user 100 within the living space 3a.
　［５．ブース内での気流の流れ］
　次に、第１送風モードおよび第２送風モードにおいて生成される気流の流れについて、図４～図７を用いて説明する。より詳細には、利用者１００の着座場所別に、利用者１００がブース２の中央に着座する場合と、利用者１００がブース２の端部に着座する場合と、についてそれぞれ説明する。 [5. Air flow inside the booth]
Next, the airflow generated in the first airflow mode and the second airflow mode will be described with reference to Figures 4 to 7. More specifically, the cases where the user 100 sits in the center of the booth 2 and where the user 100 sits at the end of the booth 2 will be described.
　図５は、ブース中央に着座する利用者１００に対して、送風装置１の第２送風モードにおいて生成される気流の流れを示す正面図である。図６は、ブース端部に着座する利用者１００に対して、送風装置１の第１送風モードにおいて生成される気流の流れを示す正面図である。図７は、ブース端部に着座する利用者１００に対して、送風装置１の第２送風モードにおいて生成される気流の流れを示す正面図である。 Figure 5 is a front view showing the airflow generated in the second blowing mode of the blower 1 for a user 100 seated in the center of the booth. Figure 6 is a front view showing the airflow generated in the first blowing mode of the blower 1 for a user 100 seated at the end of the booth. Figure 7 is a front view showing the airflow generated in the second blowing mode of the blower 1 for a user 100 seated at the end of the booth.
　ここで、第１送風モードでは、２つの第１吹出ノズル１６へ送風を行う２つの送風機２０は、いずれも送風量１００ｍ３／ｈで作動し、２つの第２吹出ノズル１７へ送風を行う２つの送風機２０は、いずれも送風量５０ｍ３／ｈで作動するように制御されるものとする。 Here, in the first air blowing mode, the two blowers 20 blowing air to the two first blowing nozzles 16 are both controlled to operate at an air volume of 100 m3 /h, and the two blowers 20 blowing air to the two second blowing nozzles 17 are both controlled to operate at an air volume of 50 m3 /h.
　また、第２送風モードでは、２つの第１吹出ノズル１６へ送風を行う２つの送風機２０は、いずれも送風量１００ｍ３／ｈで作動するように制御されるものとする。以下、特記しない部分に関しては、上記主要な気流の流れと同様のものとし、適宜省略しながら説明する。 In the second blowing mode, each of the two blowers 20 that blow air to the two first blowing nozzles 16 is controlled to operate at an air volume of 100 m3 /h. In the following, unless otherwise specified, the following description will be made assuming that the flow is the same as the main airflow described above, and will be omitted as appropriate.
　［５．１　第１送風モード：利用者がブース中央に着座する場合］
　まず、図４を参照して、利用者１００がブース２の着座部１３の中央に着座する場合に、送風装置１が行う第１送風モードについて説明する。 [5.1 First airflow mode: when the user sits in the center of the booth]
First, with reference to FIG. 4, the first air blowing mode performed by the air blowing device 1 when the user 100 is seated in the center of the seating section 13 of the booth 2 will be described.
　送風装置１は、第１送風モードにおいて、利用者１００の方向へ直進する気流を生成する。ここでは、図４に示すように、利用者１００の鉛直方向上方に位置する吹出ノズル１４ｂと吹出ノズル１４ｃとが第１吹出ノズル１６として特定され、それ以外の吹出ノズル１４である吹出ノズル１４ａと吹出ノズル１４ｄとが第２吹出ノズル１７として特定される。 In the first blowing mode, the blower device 1 generates an airflow that travels straight toward the user 100. Here, as shown in FIG. 4, blowing nozzle 14b and blowing nozzle 14c located vertically above the user 100 are identified as the first blowing nozzle 16, and the other blowing nozzles 14, blowing nozzle 14a and blowing nozzle 14d, are identified as the second blowing nozzle 17.
　送風装置１が第１送風モードで運転を開始すると、第１吹出ノズル１６へと送風を行う送風機２０ｂおよび送風機２０ｃが作動し、給気口２１からブース２外の空気が吸い込まれ、吹出ノズル１４ｂの吹出口１５ｂおよび吹出ノズル１４ｃの吹出口１５ｃそれぞれから気流ＡＦ１５ｂが吹き出される。 When the blower 1 starts operating in the first blowing mode, the blowers 20b and 20c that blow air to the first blowing nozzle 16 are activated, air outside the booth 2 is sucked in through the air intake 21, and airflow AF15b is blown out from the blowing outlet 15b of the blowing nozzle 14b and the blowing outlet 15c of the blowing nozzle 14c.
　一方で、第２吹出ノズル１７へと送風を行う送風機２０ａおよび送風機２０ｄも作動し、給気口２１からブース２外の空気が吸い込まれ、吹出ノズル１４ａの吹出口１５ａおよび吹出ノズル１４ｄの吹出口１５ｄそれぞれから気流ＡＦ１５ａが吹き出される。 Meanwhile, blowers 20a and 20d, which blow air to second blowing nozzle 17, also operate, sucking air from outside booth 2 through air intake 21, and blowing airflow AF15a out from blowing outlet 15a of blowing nozzle 14a and blowing outlet 15d of blowing nozzle 14d.
　気流ＡＦ１５ａおよび気流ＡＦ１５ｂが居室空間３ａに吹き出されると、気流ＡＦ１５ａおよび気流ＡＦ１５ｂの周囲の空間の空気が気流ＡＦ１５ａおよび気流ＡＦ１５ｂに引き寄せられ、利用者１００を中心にして居室空間全体の空気が気流ＡＦ３１としてトップボード６側からフロアボード４側に向かって下降する。 When the airflows AF15a and AF15b are blown out into the living space 3a, the air in the space around the airflows AF15a and AF15b is drawn toward the airflows AF15a and AF15b, and the air in the entire living space, centered around the user 100, descends as airflow AF31 from the top board 6 side toward the floor board 4 side.
　気流ＡＦ１５ａの一部は、気流ＡＦ１５ｂに引き寄せられて気流ＡＦ１５ｂと合流したり、フロアボード４側からトップボード６側へと流れる還流を形成したりする。 Part of the airflow AF15a is attracted to the airflow AF15b and merges with it, or forms a return current that flows from the floorboard 4 side to the topboard 6 side.
　以上のようにして、送風装置１は、第１送風モードにおいて、第１吹出ノズル１６および第２吹出ノズル１７へ送風を行うことによって、利用者１００に向かって流れる気流ＡＦ３１を生成する。 In this manner, in the first air blowing mode, the air blowing device 1 blows air through the first air outlet nozzle 16 and the second air outlet nozzle 17, thereby generating an airflow AF31 that flows toward the user 100.
　なお、第１吹出ノズル１６への送風量は、第２吹出ノズル１７への送風量よりも多いので、上述した通り、気流ＡＦ１５ｂに気流ＡＦ１５ａが、より強く引き寄せられるので、直進性の高い気流となる。つまり、第１送風モードでは、利用者１００に風が直進的に当たるので、利用者１００に涼しく感じさせることができる。 The amount of air blown to the first blowing nozzle 16 is greater than the amount of air blown to the second blowing nozzle 17, so that, as described above, the airflow AF15a is more strongly attracted to the airflow AF15b, resulting in an airflow with a high degree of straightness. In other words, in the first air blowing mode, the air blown to the user 100 goes straight, making the user 100 feel cool.
　［５．２　第２送風モード：利用者がブース中央に着座する場合］
　次に、図５を参照して、利用者１００がブース２の着座部１３の中央に着座する場合に、送風装置１が行う第２送風モードについて説明する。 [5.2 Second airflow mode: when the user sits in the center of the booth]
Next, the second air blowing mode performed by the air blowing device 1 when the user 100 is seated in the center of the seating section 13 of the booth 2 will be described with reference to FIG.
　ここでは、図５に示すように、利用者１００の鉛直方向上方に位置する吹出ノズル１４ｂと吹出ノズル１４ｃとが第１吹出ノズル１６として特定され、それ以外の吹出ノズル１４である吹出ノズル１４ａと吹出ノズル１４ｄとが第２吹出ノズル１７として特定される。 Here, as shown in FIG. 5, blow-out nozzle 14b and blow-out nozzle 14c located vertically above user 100 are identified as first blow-out nozzle 16, and the other blow-out nozzles 14, blow-out nozzle 14a and blow-out nozzle 14d, are identified as second blow-out nozzle 17.
　送風装置１が第２送風モードで運転を開始すると、第２吹出ノズル１７へ送風する送風機２０の運転のみが行われる。つまり、第１吹出ノズル１６へ送風を行う送風機２０ｂおよび送風機２０ｃは作動せず、第２吹出ノズル１７へ送風を行う送風機２０ａおよび送風機２０ｄが作動する。 When the blower device 1 starts operating in the second blowing mode, only the blower 20 that blows air to the second blowing nozzle 17 is operated. In other words, the blower 20b and the blower 20c that blow air to the first blowing nozzle 16 are not operated, and the blower 20a and the blower 20d that blow air to the second blowing nozzle 17 are operated.
　送風機２０ａおよび送風機２０ｄが動作を開始すると、給気口２１からブース２外の空気が吸い込まれ、吹出ノズル１４ａの吹出口１５ａおよび吹出ノズル１４ｄの吹出口１５ｄそれぞれから気流ＡＦ１５ａが吹き出される。 When blowers 20a and 20d start operating, air outside the booth 2 is sucked in through the air intake 21, and airflow AF15a is blown out from the outlet 15a of blow nozzle 14a and the outlet 15d of blow nozzle 14d.
　第２送風モードでは、第１吹出ノズル１６への送風は行われないので、気流ＡＦ１５ｂは形成されず、第２吹出ノズル１７から生じた気流ＡＦ１５ａのみが形成される。そのため、第１送風モードのように、気流ＡＦ１５ａと気流ＡＦ１５ｂとの間で引き寄せあう力は生じない。 In the second airflow mode, air is not blown to the first blowing nozzle 16, so airflow AF15b is not formed, and only airflow AF15a is generated from the second blowing nozzle 17. Therefore, unlike the first airflow mode, no attractive force is generated between the airflows AF15a and AF15b.
　一方で、第２吹出ノズル１７から吹き出される気流ＡＦ１５ａは、壁面（サイドパネル５ａ、５ｂ）近傍を流れる気流であるので、コアンダ効果が働き、サイドパネル５に引き寄せられて、気流ＡＦ１５ｃとなる。気流ＡＦ１５ｃは、サイドパネル５近傍をトップボード６側からフロアボード４側に向かって流れる気流である。 On the other hand, the airflow AF15a blown out from the second blowing nozzle 17 is an airflow that flows near the wall surface ( side panels 5a, 5b), so the Coanda effect comes into play and the airflow is drawn to the side panel 5, becoming airflow AF15c. Airflow AF15c is an airflow that flows near the side panel 5 from the top board 6 side toward the floor board 4 side.
　気流ＡＦ１５ｃは、利用者１００をゆるやかに避けて居室空間３ａの内部空間を通り、フロアボード４側に到達する。気流ＡＦ１５ｃは、サイドパネル５ａおよびサイドパネル５ｂに沿って居室空間３ａ内を下降した後、第１送風モードと同様に、排気流（気流ＡＦ３１ａ、図２参照）または還流気流（気流ＡＦ４１）に変化する。 Airflow AF15c passes through the interior space of living space 3a, gently avoiding the user 100, and reaches the floorboard 4 side. After descending within living space 3a along side panels 5a and 5b, airflow AF15c changes to an exhaust airflow (airflow AF31a, see Figure 2) or a return airflow (airflow AF41), as in the first airflow mode.
　以上のようにして、送風装置１は、第２送風モードにおいて、第２吹出ノズル１７のみに選択的に送風を行うことで、居室空間３ａ内でサイドパネル５に沿って下降する空気の流れを形成することができる。つまり、第２送風モードでは、利用者１００に風が直進的に当たらないので、利用者１００が寒く感じることを防ぐことができる。 In this way, in the second air blowing mode, the air blowing device 1 selectively blows air only through the second outlet nozzle 17, thereby forming an air flow that descends along the side panel 5 within the living space 3a. In other words, in the second air blowing mode, the air does not blow directly at the user 100, preventing the user 100 from feeling cold.
　［５．３　第１送風モード：利用者がブース端部に着座する場合］
　次に、図６を参照して、利用者１００がブース端部（着座部１３の中央以外）に着座する場合に、送風装置１が行う第１送風モードについて説明する。本例では、ブース端部に着座する、とは、利用者１００が着座部１３のサイドパネル５ａ側に偏って座った状態であるとして説明する。 [5.3 First airflow mode: when the user sits at the edge of the booth]
Next, the first air blowing mode performed by the air blower 1 when the user 100 is seated at the booth edge (other than the center of the seating section 13) will be described with reference to Fig. 6. In this example, "seating at the booth edge" will be described as a state in which the user 100 is seated biased toward the side panel 5a of the seating section 13.
　ここでは、図６に示すように、利用者１００の鉛直方向上方に位置する吹出ノズル１４ａと吹出ノズル１４ｂとが第１吹出ノズル１６として特定され、それ以外の吹出ノズル１４である吹出ノズル１４ｃと吹出ノズル１４ｄとが第２吹出ノズル１７として特定される。 Here, as shown in FIG. 6, blow-out nozzle 14a and blow-out nozzle 14b located vertically above user 100 are identified as first blow-out nozzle 16, and the other blow-out nozzles 14, blow-out nozzle 14c and blow-out nozzle 14d, are identified as second blow-out nozzle 17.
　送風装置１が第１送風モードで運転を開始すると、第１吹出ノズル１６へ送風を行う送風機２０ａおよび送風機２０ｂが作動し、給気口２１からブース２外の空気が吸い込まれ、吹出ノズル１４ａの吹出口１５ａおよび吹出ノズル１４ｂの吹出口１５ｂそれぞれから気流ＡＦ１５ｂが吹き出される。 When the blower 1 starts operating in the first blowing mode, the blowers 20a and 20b that blow air to the first blowing nozzle 16 are activated, air outside the booth 2 is sucked in through the air intake 21, and airflow AF15b is blown out from the blowing outlet 15a of the blowing nozzle 14a and the blowing outlet 15b of the blowing nozzle 14b.
　一方で、第２吹出ノズル１７へ送風を行う送風機２０ｃおよび送風機２０ｄも作動し、給気口２１からブース２外の空気が吸い込まれ、吹出ノズル１４ｃの吹出口１５ｃおよび吹出ノズル１４ｄの吹出口１５ｄそれぞれから気流ＡＦ１５ａが吹き出される。 Meanwhile, blowers 20c and 20d, which blow air to second blowing nozzle 17, also operate, sucking air from outside booth 2 through air inlet 21, and blowing airflow AF15a out from blowing outlet 15c of blowing nozzle 14c and blowing outlet 15d of blowing nozzle 14d.
　気流ＡＦ１５ａおよび気流ＡＦ１５ｂが居室空間３ａに吹き出されると、気流ＡＦ１５ａおよび気流ＡＦ１５ｂの周囲の空間の空気が気流ＡＦ１５ａおよび気流ＡＦ１５ｂに引き寄せられ、利用者１００を中心にして居室空間３ａ全体の空気がトップボード６側からフロアボード４側に向かって下降する。 When the airflows AF15a and AF15b are blown out into the living space 3a, the air in the space around the airflows AF15a and AF15b is drawn toward the airflows AF15a and AF15b, and the air in the entire living space 3a, centered around the user 100, descends from the top board 6 side toward the floor board 4 side.
　気流ＡＦ１５ａの一部は、気流ＡＦ１５ｂに引き寄せられて気流ＡＦ１５ｂと合流したり、フロアボード４側からトップボード６側へと流れる還流を形成したりする。 Part of the airflow AF15a is attracted to the airflow AF15b and merges with it, or forms a return current that flows from the floorboard 4 side to the topboard 6 side.
　以上のようにして、送風装置１は、第１送風モードにおいて、利用者１００がブース端部に座った場合でも、第１吹出ノズル１６および第２吹出ノズル１７に送風を行うことによって、利用者１００に向かって流れる気流を生成することができる。 In this way, in the first air blowing mode, the air blowing device 1 can generate an airflow that flows toward the user 100 by blowing air through the first air blowing nozzle 16 and the second air blowing nozzle 17, even if the user 100 is sitting at the end of the booth.
　なお、第１吹出ノズル１６への送風量が第２吹出ノズル１７への送風量よりも多いので、上述したとおり、気流ＡＦ１５ｂに気流ＡＦ１５ａが引き寄せられて、直進性の高い気流となる。つまり、第１送風モードでは、利用者１００に風が直進的に当たるので、利用者１００に涼しく感じさせることができる。 In addition, since the amount of air blown to the first blowing nozzle 16 is greater than the amount of air blown to the second blowing nozzle 17, as described above, the airflow AF15a is attracted to the airflow AF15b, resulting in a highly linear airflow. In other words, in the first airflow mode, the air blown to the user 100 moves in a straight line, making the user 100 feel cool.
　［５．４　第２送風モード：利用者が着座部端部に着座する場合］
　次に、図７を参照して、利用者１００が、ブース端部（着座部１３の中央以外）に着座する場合に、送風装置１が行う第２送風モードについて説明する。 [5.4 Second airflow mode: when the user sits on the edge of the seat]
Next, the second air blowing mode performed by the air blowing device 1 when the user 100 is seated at the booth end (other than the center of the seating section 13) will be described with reference to FIG.
　ここでは、図７に示すように、利用者１００の鉛直方向上方に位置する吹出ノズル１４ａと吹出ノズル１４ｂとが第１吹出ノズル１６として特定され、それ以外の吹出ノズル１４である吹出ノズル１４ｃと吹出ノズル１４ｄとが第２吹出ノズル１７として特定される。 Here, as shown in FIG. 7, blow-out nozzle 14a and blow-out nozzle 14b located vertically above user 100 are identified as first blow-out nozzle 16, and the other blow-out nozzles 14, blow-out nozzle 14c and blow-out nozzle 14d, are identified as second blow-out nozzle 17.
　送風装置１が第２送風モードで運転を開始すると、第２吹出ノズル１７へ送風する送風機２０の運転のみが行われる。つまり、第１吹出ノズル１６に送風を行う送風機２０ａおよび送風機２０ｂは作動せず、第２吹出ノズル１７に送風を行う送風機２０ｃおよび送風機２０ｄが作動する。 When the blower device 1 starts operating in the second blowing mode, only the blower 20 that blows air to the second blowing nozzle 17 is operated. In other words, the blower 20a and the blower 20b that blow air to the first blowing nozzle 16 are not operated, and the blower 20c and the blower 20d that blow air to the second blowing nozzle 17 are operated.
　送風機２０ｃおよび送風機２０ｄが動作を開始すると、給気口２１からブース２外の空気が吸い込まれ、吹出ノズル１４ｃの吹出口１５ｃおよび吹出ノズル１４ｄの吹出口１５ｄそれぞれから気流ＡＦ１５ａが吹き出される。 When blowers 20c and 20d start operating, air outside booth 2 is sucked in through air intake 21, and airflow AF15a is blown out from outlet 15c of blow nozzle 14c and outlet 15d of blow nozzle 14d.
　第２送風モードでは、第１吹出ノズル１６への送風は行われないので、気流ＡＦ１５ｂは形成されず、第２吹出ノズル１７から生じた気流ＡＦ１５ａのみが形成される。そのため、第１送風モードのように、気流ＡＦ１５ａと気流ＡＦ１５ｂとの間で引き寄せあう力が生じない。 In the second airflow mode, air is not blown to the first blowing nozzle 16, so airflow AF15b is not formed, and only airflow AF15a is generated from the second blowing nozzle 17. Therefore, unlike the first airflow mode, no attractive force is generated between the airflow AF15a and the airflow AF15b.
　一方で、吹出口１５ｄから吹出される気流ＡＦ１５ａは、壁面（サイドパネル５ｂ）近傍を流れる気流であるので、コアンダ効果が働いて、サイドパネル５に引き寄せられて、全体的に気流ＡＦ１５ｃとなる。気流ＡＦ１５ｃは、サイドパネル５ｂ近傍をトップボード６側からフロアボード４側に向かって流れる気流である。 On the other hand, the airflow AF15a blown out from the air outlet 15d is an airflow that flows near the wall surface (side panel 5b), so the Coanda effect works and the airflow is drawn to the side panel 5, becoming airflow AF15c overall. Airflow AF15c is an airflow that flows near the side panel 5b from the top board 6 side toward the floor board 4 side.
　さらに、吹出口１５ｃから吹き出された気流ＡＦ１５ａの一部は、吹出口１５ｄから吹き出された気流ＡＦ１５ａに引き寄せられ、気流ＡＦ１５ｃに合流する。こうして生成された気流ＡＦ１５ｃは、利用者１００をゆるやかに避けて居室空間３ａの内部空間を通り、フロアボード４側に到達する。気流ＡＦ１５ｃは、サイドパネル５ｂに沿って居室空間３ａ内を下降した後、第１送風モードと同様に、排気流（気流ＡＦ３１ａ）または還流気流（気流ＡＦ４１）に変化する。 Furthermore, a portion of the airflow AF15a blown out from the air outlet 15c is attracted to the airflow AF15a blown out from the air outlet 15d and merges with the airflow AF15c. The airflow AF15c thus generated passes through the internal space of the living space 3a, gently avoiding the user 100, and reaches the floorboard 4 side. After descending within the living space 3a along the side panel 5b, the airflow AF15c changes to an exhaust airflow (airflow AF31a) or a return airflow (airflow AF41), as in the first airflow mode.
　以上のようにして、送風装置１は、第２送風モードにおいて、第２吹出ノズル１７のみに選択的に送風を行うことで、居室空間３ａ内でサイドパネル５ｂに沿って下降する空気の流れを形成することができる。つまり、第２送風モードでは、利用者１００に風が直進的に当たらないので、利用者が寒く感じることを防ぐことができる。 In this way, in the second air blowing mode, the air blowing device 1 selectively blows air only through the second outlet nozzle 17, thereby forming an air flow that descends along the side panel 5b within the living space 3a. In other words, in the second air blowing mode, the air does not blow directly on the user 100, preventing the user from feeling cold.
　なお、本例では、ブース端部に着座する、とは、利用者１００が着座部１３のサイドパネル５ａ側に偏って座った状態であるとして説明したが、本開示はこの例に限定されない。利用者１００が着座部１３のサイドパネル５ｂ側に偏って座った状態であっても、第２吹出ノズル１７として特定される吹出ノズル１４が変わるだけであり、同様の制御を行うことができる。 In this example, sitting at the end of the booth is described as a state in which the user 100 is seated biased toward the side panel 5a of the seating section 13, but the present disclosure is not limited to this example. Even if the user 100 is seated biased toward the side panel 5b of the seating section 13, only the blowing nozzle 14 identified as the second blowing nozzle 17 changes, and similar control can be performed.
　［６．送風運転制御］
　次に、送風装置１が行う第１送風モードおよび第２送風モードの送風運転制御について、図８を参照しながら説明する。 [6. Fan operation control]
Next, the blowing operation control in the first blowing mode and the second blowing mode performed by the blower 1 will be described with reference to FIG.
　図８は、制御部５０の構成を表す概略ブロック図である。 FIG. 8 is a schematic block diagram showing the configuration of the control unit 50.
　図８に示すように、送風装置１の制御部５０は、入力部５１と、記憶部５２と、計時部５３と、処理部５４と、出力部５５と、を備える。制御部５０は、操作パネル４０からの入力情報に基づいて複数の送風機２０ａ～２０ｄの制御を行う。 As shown in FIG. 8, the control unit 50 of the blower device 1 includes an input unit 51, a memory unit 52, a timer unit 53, a processing unit 54, and an output unit 55. The control unit 50 controls the multiple blowers 20a to 20d based on input information from the operation panel 40.
　入力部５１は、操作パネル４０から入力された情報（利用者１００の着座位置情報および送風モード情報）を受け付けて、処理部５４に出力する。着座位置情報は、着座部１３に着座した利用者１００の位置に関する情報であり、送風モード情報は、利用者１００が選択した第１送風モードまたは第２送風モードに関する情報である。 The input unit 51 accepts information input from the operation panel 40 (seating position information of the user 100 and airflow mode information) and outputs it to the processing unit 54. The seating position information is information about the position of the user 100 seated on the seating section 13, and the airflow mode information is information about the first airflow mode or the second airflow mode selected by the user 100.
　記憶部５２は、第１吹出ノズル１６に対応する送風機２０の風量の情報と、第２吹出ノズル１７に対応する送風機２０の風量の情報と、を記憶する。また、記憶部５２は、操作パネル４０で入力された情報も記憶する。記憶部５２は、処理部５４からの要求に応じて、記憶した各種情報を処理部５４に出力する。 The memory unit 52 stores information on the air volume of the blower 20 corresponding to the first blowing nozzle 16 and information on the air volume of the blower 20 corresponding to the second blowing nozzle 17. The memory unit 52 also stores information inputted through the operation panel 40. The memory unit 52 outputs the various stored information to the processing unit 54 in response to a request from the processing unit 54.
　計時部５３は、送風装置１の送風運転開始からの時間を計測し、運転時間を処理部５４に出力する。 The timing unit 53 measures the time from when the blower device 1 starts blowing air, and outputs the operating time to the processing unit 54.
　処理部５４は、入力部５１からの情報と、記憶部５２からの各種情報（送風機の風量情報等）と、計時部５３からの時間情報と、を受け付ける。処理部５４は、受け付けた各情報をもとに、複数の送風機２０（送風機２０ａ、送風機２０ｂ、送風機２０ｃ、送風機２０ｄ）の送風動作を決定する。処理部５４は、決定した送風動作に関する情報（制御情報）を出力部５５に出力する。 The processing unit 54 receives information from the input unit 51, various information from the memory unit 52 (such as information about the air volume of the blower), and time information from the timing unit 53. Based on the received information, the processing unit 54 determines the blowing operation of the multiple blowers 20 (blower 20a, blower 20b, blower 20c, blower 20d). The processing unit 54 outputs information (control information) related to the determined blowing operation to the output unit 55.
　出力部５５は、処理部５４から受け付けた制御情報を送風機２０に出力する。 The output unit 55 outputs the control information received from the processing unit 54 to the blower 20.
　そして、複数の送風機２０（送風機２０ａ、送風機２０ｂ、送風機２０ｃ、送風機２０ｄ）それぞれは、出力部５５から出力された制御情報に応じて、制御情報に基づいた送風量にて送風動作を実行する。 Then, each of the multiple blowers 20 (blower 20a, blower 20b, blower 20c, blower 20d) performs a blowing operation at an air volume based on the control information in response to the control information output from the output unit 55.
　以上のようにして、制御部５０は、送風装置１における複数の送風機２０に送風動作を実行させる。 In this manner, the control unit 50 causes the multiple blowers 20 in the blower device 1 to perform blowing operations.
　次に、図９を参照して、送風装置１が行う送風運転制御の流れについて説明する。 Next, the flow of the blowing operation control performed by the blower device 1 will be explained with reference to FIG. 9.
　図９は、送風装置１における制御を示すフローチャートである。 FIG. 9 is a flowchart showing the control of the blower 1.
　図９に示すように、送風装置１の送風運転が開始されると、制御部５０は、操作パネル４０からの入力情報として、利用者１００の着座位置情報と、利用者１００が選択した送風モード情報と、を取得する（Ｓ０１）。 As shown in FIG. 9, when the blowing operation of the blower device 1 is started, the control unit 50 acquires the seating position information of the user 100 and the blowing mode information selected by the user 100 as input information from the operation panel 40 (S01).
　次に、制御部５０は、取得した利用者１００の着座位置情報（ブース中央またはブース端部）に基づいて、４つの吹出ノズル１４のうち、利用者１００の鉛直方向上方に位置する第１吹出ノズル１６を特定する（Ｓ０２）。なお、ステップＳ０２では、４つの吹出ノズル１４のうち、第１吹出ノズル１６以外の吹出ノズル１４である第２吹出ノズル１７も併せて特定される。 Next, the control unit 50 identifies the first blowing nozzle 16 of the four blowing nozzles 14 that is located vertically above the user 100 based on the acquired seating position information of the user 100 (center of the booth or end of the booth) (S02). Note that in step S02, the second blowing nozzle 17, which is the blowing nozzle 14 other than the first blowing nozzle 16, is also identified among the four blowing nozzles 14.
　なお、本例において、ステップＳ０２で特定される着座位置情報は、利用者がブース中央またはブース端部のどちらに着座しているかを特定する情報であるが、ブース端部のうち、利用者１００が着座部１３のサイドパネル５ａ側またはサイドパネル５ｂ側のいずれに偏って座った状態であるかについても特定できる情報である。制御部５０は、利用者１００が着座した位置に応じて、適切に第１吹出ノズル１６および第２吹出ノズル１７を選択する。 In this example, the seating position information identified in step S02 is information that identifies whether the user is seated in the center of the booth or at the edge of the booth, but is also information that can identify whether the user 100 is seated biased toward the side panel 5a or side panel 5b of the seating section 13 at the edge of the booth. The control unit 50 appropriately selects the first blowing nozzle 16 and the second blowing nozzle 17 depending on the seating position of the user 100.
　そして、制御部５０は、取得した送風モード情報に基づいて、利用者１００が選択した送風モードが第１送風モードであるか否かを判定する（Ｓ０３）。 Then, the control unit 50 determines whether the airflow mode selected by the user 100 is the first airflow mode based on the acquired airflow mode information (S03).
　ステップＳ０３での判定の結果、第１送風モードであれば（Ｓ０３のＹｅｓ）、ステップＳ０４ａに移行する。一方、判定の結果、第１送風モードではない、つまり第２送風モードであれば（Ｓ０３のＮｏ）、ステップＳ０４ｂに移行する。 If the result of the determination in step S03 is that the first airflow mode is selected (Yes in S03), the process proceeds to step S04a. On the other hand, if the result of the determination is that the first airflow mode is not selected, i.e., that the second airflow mode is selected (No in S03), the process proceeds to step S04b.
　ステップＳ０４ａに移行すると、制御部５０は、第１吹出ノズル１６へ送風する送風機２０と、第２吹出ノズル１７へ送風する送風機２０とに送風動作を実行させる（Ｓ０５ａ）。 When the process proceeds to step S04a, the control unit 50 causes the blower 20 to blow air to the first blowing nozzle 16 and the blower 20 to blow air to the second blowing nozzle 17 to perform blowing operations (S05a).
　一方、ステップＳ０４ｂに移行すると、制御部５０は、第１吹出ノズル１６へ送風する送風機２０の送風動作は行わず、第２吹出ノズル１７へ送風する送風機２０のみに送風動作を実行させる（Ｓ０５ｂ）。 On the other hand, when the process proceeds to step S04b, the control unit 50 does not cause the blower 20 to blow air to the first blowing nozzle 16, but causes only the blower 20 to blow air to the second blowing nozzle 17 to perform the blowing operation (S05b).
　その後、制御部５０は、ステップＳ０５ａまたはステップＳ０５ｂにおいて、送風機２０による送風運転の開始時間を起点として計測された時間が、所定時間を経過したか否かの判定を行う（Ｓ０６）。ここで、所定時間は、例えば、１分に設定される。 Then, in step S05a or step S05b, the control unit 50 determines whether the time measured from the start time of the blowing operation by the blower 20 has elapsed a predetermined time (S06). Here, the predetermined time is set to, for example, one minute.
　そして、ステップＳ０６での判定の結果、所定時間が経過していない場合は（Ｓ０６のＮｏ）、制御部５０は、送風機２０による送風運転動作をそのまま継続させる（Ｓ０６に戻る）。 If the result of the determination in step S06 is that the predetermined time has not elapsed (No in S06), the control unit 50 continues the blowing operation of the blower 20 (return to S06).
　また、判定の結果、所定時間が経過した場合には（Ｓ０６のＹｅｓ）、ステップＳ０７に移行する。 If the result of the determination is that the predetermined time has elapsed (Yes in S06), the process proceeds to step S07.
　ステップＳ０７では、送風装置１の運転停止信号が入力されたか否かが判定される。送風装置１の運転停止信号が入力されていなければ（Ｓ０７のＮｏ）、制御部５０は、ステップＳ０３に戻り、送風装置１の運転の実行を継続する。この際、計測された時間はリセットされる。 In step S07, it is determined whether or not a signal to stop operation of the blower device 1 has been input. If a signal to stop operation of the blower device 1 has not been input (No in S07), the control unit 50 returns to step S03 and continues to execute the operation of the blower device 1. At this time, the measured time is reset.
　一方で、ステップＳ０６での判定の結果、所定時間が経過し（Ｓ０６のＹｅｓ）、運転停止信号が入力された場合（Ｓ０７のＹｅｓ）には、ステップＳ０８に移行し、送風装置１は、送風機２０を停止させ、運転終了状態または待機状態となる。なお、送風装置１は、所定時間経過を待たずに、運転停止信号を受け付けた場合には直ちに送風運転を停止することも可能である。 On the other hand, if the result of the determination in step S06 is that the predetermined time has elapsed (Yes in S06) and an operation stop signal has been input (Yes in S07), the process proceeds to step S08, and the blower device 1 stops the blower 20 and enters an operation end state or standby state. Note that the blower device 1 can also stop the blower operation immediately when it receives an operation stop signal without waiting for the predetermined time to elapse.
　以上のようにして、本実施の形態における送風装置１は、利用者１００の着座位置に対応して送風機２０の送風動作を制御して、第１送風モードと第２送風モードとの切り替え動作を実行することができる。 In this manner, the blower device 1 in this embodiment can control the blowing operation of the blower 20 in accordance with the seating position of the user 100, and can switch between the first and second blowing modes.
　以上、第１の実施の形態に係る送風装置１によれば、以下の効果を享受することができる。 As described above, the blower device 1 according to the first embodiment provides the following advantages.
　（１）送風装置１は、フロアボード４と、複数のサイドパネル５と、トップボード６とから形成される居室空間３ａと、居室空間３ａへ空気を供給するための給気口２１と、居室空間３ａの空気を排出するための排気口２２と、利用者１００が着座可能な着座部１３と、を有するブース２に設置される。そして、送風装置１は、居室空間３ａにおいて、着座部１３に座る利用者１００の頭上となる居室空間３ａのトップボード６側に送風面が設置され、トップボード６からオフセットして配置される。送風装置１は、トップボード６側からフロアボード４側に向かって流れる空気を吹き出すスリット状の吹出口をそれぞれが有する４つの吹出ノズル１４と、給気口２１から吸い込んだ空気を４つの吹出ノズル１４にそれぞれ送風する４つの送風機２０と、４つの送風機２０の動作を制御する制御部５０と、を備える。４つの吹出ノズル１４は、それぞれの吹出口１５が同一面上に位置するように間隙を有して並設される。制御部５０は、４つの吹出ノズル１４のうち、着座部１３に着座した利用者１００の鉛直方向上方に位置する吹出ノズル１４を第１吹出ノズル１６として特定し、第１吹出ノズル１６以外の吹出ノズル１４を第２吹出ノズル１７として特定する。制御部５０は、給気口２１から吸い込まれた空気を第１吹出ノズル１６および第２吹出ノズル１７に送風する第１送風モードと、給気口２１から吸い込まれた空気を第１吹出ノズル１６に送風せずに第２吹出ノズル１７に選択的に送風する第２送風モードとを切り替えて、４つの送風機２０を制御する。 (1) The blower 1 is installed in a booth 2 having an occupant space 3a formed by a floorboard 4, a plurality of side panels 5, and a top board 6, an air inlet 21 for supplying air to the occupant space 3a, an exhaust port 22 for discharging air from the occupant space 3a, and a seating area 13 on which a user 100 can sit. The blower 1 is installed in the occupant space 3a on the top board 6 side of the occupant space 3a, above the head of a user 100 sitting on the seating area 13, and is offset from the top board 6. The blower 1 includes four blowing nozzles 14, each having a slit-shaped outlet for blowing air flowing from the top board 6 side toward the floorboard 4 side, four blowers 20 for blowing air sucked in from the air inlet 21 to each of the four blowing nozzles 14, and a control unit 50 for controlling the operation of the four blowers 20. The four blowing nozzles 14 are arranged side by side with a gap between them so that the respective blowing ports 15 are located on the same plane. The control unit 50 identifies, among the four blowing nozzles 14, the blowing nozzle 14 located vertically above the user 100 seated on the seating unit 13 as the first blowing nozzle 16, and identifies the blowing nozzles 14 other than the first blowing nozzle 16 as the second blowing nozzle 17. The control unit 50 controls the four blowers 20 by switching between a first blowing mode in which air sucked from the air supply port 21 is blown to the first blowing nozzle 16 and the second blowing nozzle 17, and a second blowing mode in which air sucked from the air supply port 21 is selectively blown to the second blowing nozzle 17 without blowing to the first blowing nozzle 16.
　こうした構成によれば、送風モードを切り替えることによって、第１送風モードにおいては、利用者１００の鉛直方向上方から空気を吹き出し、利用者１００に直進的に当たる気流を形成しながら送風を行い、第２送風モードにおいては、利用者１００の鉛直方向上方以外の領域から空気を吹き出し、利用者１００に気流を当てずに送風を行うことができる。 With this configuration, by switching the airflow mode, in the first airflow mode, air is blown from above the user 100 in the vertical direction, forming an airflow that hits the user 100 in a straight line, while in the second airflow mode, air is blown from an area other than above the user 100 in the vertical direction, and air is blown without hitting the user 100 with the airflow.
　これにより、居室空間３ａ内の換気（居室空間３ａ外から取り込んだ空気を居室空間３ａ内へ送風し、居室空間３ａ内の空気を入れ替える）をする際に、居室空間３ａ内に漫然と空気を送風するのではなく、冬期においては、第２送風モードに切り替えて、着座した利用者１００を避けて送風を行うようにできる。一方、夏期においては、第１送風モードに切り替えて、着座した利用者１００に向けて送風を行うようにできる。 As a result, when ventilating the living space 3a (air taken in from outside the living space 3a is blown into the living space 3a to replace the air in the living space 3a), rather than blowing air randomly into the living space 3a, in winter the mode can be switched to the second air blowing mode so that air is blown away from seated users 100. On the other hand, in summer the mode can be switched to the first air blowing mode so that air is blown toward seated users 100.
　よって、冬期では、利用者１００に気流が当たって利用者１００が寒く感じてしまうことが抑制され、夏期では、利用者１００に気流が当たって利用者に涼しく感じさせることができる。つまり、居室空間３ａにおける送風装置１において、通年で快適性を保ちながら換気することができる。 As a result, in winter, the air current hitting the user 100 and making the user 100 feel cold is suppressed, and in summer, the air current hitting the user 100 makes the user feel cool. In other words, the air blower 1 in the living space 3a can ventilate while maintaining comfort all year round.
　（２）送風装置１では、制御部５０は、第１送風モードにおいて、第１吹出ノズル１６の吹出口１５から吹き出す空気の風量が、第２吹出ノズル１７の吹出口１５から吹き出す空気の風量よりも大きくなるように４つの送風機２０を制御する。 (2) In the blower device 1, the control unit 50 controls the four blowers 20 in the first blowing mode so that the volume of air blown out from the outlet 15 of the first blowing nozzle 16 is greater than the volume of air blown out from the outlet 15 of the second blowing nozzle 17.
　このようにすることで、送風装置１では、第１送風モードにおいて、第２吹出ノズル１７から吹き出して形成される気流が第１吹出ノズル１６から吹き出して形成される気流に引き寄せられ、気流全体が合わさって直進性の高い気流（面気流）を生成することができる。つまり、利用者１００に向けて直進性の高い気流を送風することができる。これにより、利用者１００に、より強く気流を感じさせることができ、快適性を向上させることができる。 By doing this, in the first air blowing mode, the airflow formed by blowing out from the second blowing nozzle 17 is attracted to the airflow formed by blowing out from the first blowing nozzle 16, and the entire airflows combine to generate a highly straight-line airflow (surface airflow). In other words, a highly straight-line airflow can be blown towards the user 100. This allows the user 100 to feel the airflow more strongly, improving comfort.
　（第１の変形例）
　次に、本開示の第１の変形例について説明する。 (First Modification)
Next, a first modified example of the present disclosure will be described.
　第１の変形例に係る送風装置１ａで行う制御について、図１０および図１１を参照しながら説明する。 The control performed by the blower device 1a in the first modified example will be described with reference to Figures 10 and 11.
　図１０は、第１の変形例に係る送風装置１ａの概略機能ブロック図である。図１１は、第１の変形例に係る送風装置１ａにおける制御を示すフローチャートである。 FIG. 10 is a schematic functional block diagram of the blower device 1a according to the first modified example. FIG. 11 is a flowchart showing the control in the blower device 1a according to the first modified example.
　第１の変形例に係る送風装置１ａは、着座部１３における利用者１００の着座位置を特定するために検知部３０を備える点で、第１の実施の形態に係る送風装置１と異なる。 The blower device 1a according to the first modified example differs from the blower device 1 according to the first embodiment in that it is provided with a detection unit 30 for identifying the seating position of the user 100 in the seating section 13.
　より詳細には、第１の変形例に係る送風装置１ａでは、制御部５０ａは、検知部３０によって検知される利用者１００の着座位置情報に基づいて、第１吹出ノズル１６と第２吹出ノズル１７とを特定するものである。以下、第１の実施の形態で説明済みの内容については再度の説明を適宜省略し、第１の実施の形態と異なる点を主に説明する。 More specifically, in the blower device 1a according to the first modified example, the control unit 50a identifies the first blowing nozzle 16 and the second blowing nozzle 17 based on the seating position information of the user 100 detected by the detection unit 30. Below, the contents already explained in the first embodiment will not be explained again as appropriate, and differences from the first embodiment will be mainly explained.
　［１．第１の変形例の構成］
　第１の変形例における送風装置１ａは、図１０に示すように、検知部３０をさらに備える。 [1. Configuration of the first modified example]
As shown in FIG. 10, the air blower 1a in the first modified example further includes a detection unit 30.
　検知部３０は、利用者１００が着座部１３に着座する位置を検知するためのセンサである。検知部３０は、例えば、感圧センサであり、着座部１３の着座面近傍に配置される。検知部３０は、着座部１３上の利用者１００の位置を検知できれば、この形態に限られず、例えば、サーモカメラ等、居室空間３ａ内に配置できるものであって、温度情報等から利用者１００の着座位置を特定できるような装置でもよい。 The detection unit 30 is a sensor for detecting the position where the user 100 sits on the seating section 13. The detection unit 30 is, for example, a pressure sensor, and is arranged near the seating surface of the seating section 13. The detection unit 30 is not limited to this form as long as it can detect the position of the user 100 on the seating section 13, and may be, for example, a device such as a thermal camera that can be arranged in the living space 3a and that can identify the seating position of the user 100 from temperature information, etc.
　検知部３０を設けることにより、利用者１００の着座した位置がブース中央またはブース端部のいずれかを検知できるのみならず、利用者１００の着座部１３上での任意の位置を検出できる。利用者１００が着座した位置を正確に検知することで、制御部５０ａは適切に第１吹出ノズル１６および第２吹出ノズル１７を選択し、利用者１００に対して適切な送風制御を行うことができる。 By providing the detection unit 30, not only can it be detected whether the user 100 is seated at the center of the booth or at the edge of the booth, but it can also detect any position on the seating area 13 where the user 100 is seated. By accurately detecting the position where the user 100 is seated, the control unit 50a can appropriately select the first blowing nozzle 16 and the second blowing nozzle 17, and perform appropriate air supply control for the user 100.
　［２．第１の変形例の送風運転制御］
　図１０に示すように、第１の変形例に係る送風装置１ａの制御部５０ａは、入力部５１と、記憶部５２と、計時部５３と、処理部５４と、出力部５５と、を備える。制御部５０ａは、検知部３０からの検知情報および操作パネル４０からの入力情報に基づいて複数の送風機２０ａ～２０ｄの制御を行う。 [2. Fan operation control of the first modified example]
10, the control unit 50a of the blower device 1a according to the first modified example includes an input unit 51, a storage unit 52, a timer unit 53, a processing unit 54, and an output unit 55. The control unit 50a controls the multiple blowers 20a to 20d based on detection information from the detection unit 30 and input information from the operation panel 40.
　入力部５１は、検知部３０で検知された情報（利用者１００の着座位置情報）および操作パネル４０で入力された情報（送風モード情報）を受け付けて、処理部５４に出力する。着座位置情報は、着座部１３に着座した利用者１００の位置に関する情報であり、送風モード情報は、利用者１００が選択した第１送風モードまたは第２送風モードに関する情報である。 The input unit 51 accepts information detected by the detection unit 30 (seating position information of the user 100) and information inputted through the operation panel 40 (airflow mode information), and outputs it to the processing unit 54. The seating position information is information relating to the position of the user 100 seated on the seating section 13, and the airflow mode information is information relating to the first airflow mode or the second airflow mode selected by the user 100.
　記憶部５２は、第１吹出ノズル１６に対応する送風機２０の風量の情報と、第２吹出ノズル１７に対応する送風機２０の風量の情報と、を記憶する。また、記憶部５２は、操作パネル４０から入力された情報も記憶する。記憶部５２は、処理部５４からの要求に応じて、記憶した各種情報を処理部５４に出力する。 The memory unit 52 stores information on the air volume of the blower 20 corresponding to the first blowing nozzle 16 and information on the air volume of the blower 20 corresponding to the second blowing nozzle 17. The memory unit 52 also stores information input from the operation panel 40. The memory unit 52 outputs the various stored information to the processing unit 54 in response to a request from the processing unit 54.
　計時部５３は、送風装置１の送風運転開始からの時間を計測し、運転時間を処理部５４に出力する。 The timing unit 53 measures the time from when the blower device 1 starts blowing air, and outputs the operating time to the processing unit 54.
　処理部５４は、入力部５１からの情報と、記憶部５２からの各種情報（送風機の風量情報等）と、計時部５３からの時間情報と、を受け付ける。処理部５４は、受け付けた各情報をもとに、複数の送風機２０（送風機２０ａ、送風機２０ｂ、送風機２０ｃ、送風機２０ｄ）の送風動作を決定する。処理部５４は、決定した送風動作に関する情報（制御情報）を出力部５５に出力する。 The processing unit 54 receives information from the input unit 51, various information from the memory unit 52 (such as information about the air volume of the blower), and time information from the timing unit 53. Based on the received information, the processing unit 54 determines the blowing operation of the multiple blowers 20 (blower 20a, blower 20b, blower 20c, blower 20d). The processing unit 54 outputs information (control information) related to the determined blowing operation to the output unit 55.
　出力部５５は、処理部５４から受け付けた制御情報を複数の送風機２０に出力する。 The output unit 55 outputs the control information received from the processing unit 54 to the multiple fans 20.
　そして、複数の送風機２０（送風機２０ａ、送風機２０ｂ、送風機２０ｃ、送風機２０ｄ）それぞれは、出力部５５から出力された制御情報に応じて、制御情報に基づいた送風量にて送風動作を実行する。 Then, each of the multiple blowers 20 (blower 20a, blower 20b, blower 20c, blower 20d) performs a blowing operation at an air volume based on the control information in response to the control information output from the output unit 55.
　以上のようにして、制御部５０ａは、送風装置１ａにおける複数の送風機２０に送風動作を実行させる。 In this manner, the control unit 50a causes the multiple blowers 20 in the blower device 1a to perform blowing operations.
　次に、図１１を参照して、送風装置１ａで行う送風運転制御の流れについて説明する。 Next, the flow of air blowing operation control performed by the air blower 1a will be explained with reference to FIG. 11.
　図１１に示すように、送風装置１の送風運転が開始されると、制御部５０ａは、検知部３０からの入力情報として、利用者１００の着座位置情報を取得する（Ｓ１１）。 As shown in FIG. 11, when the blowing operation of the blower 1 is started, the control unit 50a acquires the seating position information of the user 100 as input information from the detection unit 30 (S11).
　次に、制御部５０ａは、取得した利用者１００の着座位置情報（ブース中央またはブース端部）に基づいて、４つの吹出ノズル１４のうち、利用者１００の鉛直方向上方に位置する第１吹出ノズル１６を特定する（Ｓ１２）。なお、ステップＳ１２では、４つの吹出ノズル１４のうち、第１吹出ノズル１６以外の吹出ノズル１４である第２吹出ノズル１７も併せて特定される。 Then, the control unit 50a identifies the first blowing nozzle 16 of the four blowing nozzles 14 that is located vertically above the user 100 based on the acquired seating position information of the user 100 (center of the booth or end of the booth) (S12). Note that in step S12, the second blowing nozzle 17, which is the blowing nozzle 14 other than the first blowing nozzle 16, is also identified among the four blowing nozzles 14.
　続いて、制御部５０ａは、操作パネル４０からの入力情報として、利用者１００が選択した送風モード情報を取得する（Ｓ１３）。 Then, the control unit 50a acquires the airflow mode information selected by the user 100 as input information from the operation panel 40 (S13).
　そして、制御部５０ａは、取得した送風モード情報に基づいて、利用者１００が選択した送風モードに対応する送風機２０を動作させる（Ｓ１４）。具体的には、制御部５０ａは、第１の実施の形態における制御部５０が行うステップＳ０３からステップＳ０５ａまたはステップＳ０５ｂまでを実行する（図９参照）。 Then, the control unit 50a operates the blower 20 corresponding to the blowing mode selected by the user 100 based on the acquired blowing mode information (S14). Specifically, the control unit 50a executes steps S03 to S05a or S05b that are performed by the control unit 50 in the first embodiment (see FIG. 9).
　その後、制御部５０ａは、ステップＳ１４において送風機２０による送風運転の開始時間を起点として計測された時間が、所定時間を経過したか否かの判定を行う（Ｓ１５）。ここで、所定時間は、例えば、１分に設定される。 Then, the control unit 50a determines whether the time measured from the start time of the blowing operation by the blower 20 in step S14 has elapsed a predetermined time (S15). Here, the predetermined time is set to, for example, one minute.
　そして、ステップＳ１５での判定の結果、所定時間が経過していない場合は（Ｓ１５のＮｏ）、制御部５０ａは、送風機２０による送風運転動作をそのまま継続させる（Ｓ１５に戻る）。 If the result of the determination in step S15 is that the predetermined time has not elapsed (No in S15), the control unit 50a continues the blowing operation of the blower 20 (return to S15).
　一方、判定の結果、所定時間が経過した場合には（Ｓ１５のＹｅｓ）、ステップＳ１６に移行する。 On the other hand, if the result of the determination is that the predetermined time has elapsed (Yes in S15), the process proceeds to step S16.
　ステップＳ１６では、送風装置１ａの運転停止信号が入力されたか否かが判定される。送風装置１ａの運転停止信号が入力されていなければ（Ｓ１６のＮｏ）、制御部５０ａは、ステップＳ１１に戻り、送風装置１ａの運転の実行を継続する。この際、計測された時間はリセットされる。 In step S16, it is determined whether or not a signal to stop operation of the blower device 1a has been input. If a signal to stop operation of the blower device 1a has not been input (No in S16), the control unit 50a returns to step S11 and continues to operate the blower device 1a. At this time, the measured time is reset.
　一方で、ステップＳ１５での判定の結果、所定時間が経過し（Ｓ１５のＹｅｓ）、運転停止信号が入力された場合（Ｓ１６のＹｅｓ）には、ステップＳ１７に移行し、送風装置１ａは、送風機２０を停止させ、運転終了状態または待機状態となる。ここで、送風装置１ａは、所定時間経過を待たずに、運転停止信号を受け付けた場合には直ちに送風運転を停止することも可能である。 On the other hand, if the result of the determination in step S15 is that the predetermined time has elapsed (Yes in S15) and an operation stop signal has been input (Yes in S16), the process proceeds to step S17, and the blower device 1a stops the blower 20 and enters an operation end state or standby state. Here, the blower device 1a can also immediately stop blowing operation if it receives an operation stop signal without waiting for the predetermined time to elapse.
　以上のようにして、第１の変形例における送風装置１ａは、検知部３０によって検知される利用者１００の着座位置に対応して複数の送風機２０の送風動作を制御して、第１送風モードと第２送風モードとの切り替え動作を実行することができる。 In this way, the air blowing device 1a in the first modified example can control the air blowing operation of the multiple air blowers 20 in response to the seating position of the user 100 detected by the detection unit 30, and can switch between the first air blowing mode and the second air blowing mode.
　以上、第１の変形例に係る送風装置１ａによれば、上述した効果（１）および効果（２）とともに、以下の効果を享受することができる。 As described above, according to the blower device 1a of the first modified example, in addition to the above-mentioned effects (1) and (2), the following effects can be obtained.
　（３）送風装置１ａは、利用者１００の着座部１３における着座位置を検出する検知部３０をさらに備える。そして、制御部５０ａは、検知部３０が検出した着座位置の情報に基づいて、第１吹出ノズル１６および第２吹出ノズル１７を特定する。 (3) The air blowing device 1a further includes a detection unit 30 that detects the seating position of the user 100 in the seating section 13. The control unit 50a then identifies the first blowing nozzle 16 and the second blowing nozzle 17 based on the information on the seating position detected by the detection unit 30.
　これにより、利用者１００の着座部１３への着座位置に応じて、第１吹出ノズル１６および第２吹出ノズル１７として特定する吹出ノズル１４を切り替えることができる。つまり、送風装置１ａでは、利用者１００の着座位置によらず、利用者１００の鉛直方向上方の吹出ノズル１４が常に第１吹出ノズル１６となるように制御できる。したがって、利用者１００の着座位置によらず、夏期においては、利用者１００に直接当たる気流を形成でき、冬期においては、利用者１００に直接当たらない気流を形成できる。この結果、利用者１００が着座部１３のどの位置に座っても、利用者１００を居室空間３ａ内で快適に過ごさせながら換気を行うことができる。 This allows the blowing nozzles 14 identified as the first blowing nozzle 16 and the second blowing nozzle 17 to be switched depending on the seating position of the user 100 in the seating section 13. In other words, the blowing device 1a can be controlled so that the blowing nozzle 14 vertically above the user 100 is always the first blowing nozzle 16, regardless of the seating position of the user 100. Therefore, regardless of the seating position of the user 100, an airflow that directly hits the user 100 can be formed in the summer, and an airflow that does not directly hit the user 100 can be formed in the winter. As a result, regardless of where the user 100 sits in the seating section 13, ventilation can be performed while allowing the user 100 to spend time comfortably in the living space 3a.
　（第２の変形例）
　次に、本開示の第２の変形例について説明する。 (Second Modification)
Next, a second modified example of the present disclosure will be described.
　第２の変形例に係る送風装置１ｂで行う制御について、図１２を参照しながら説明する。図１２は、第２の変形例に係る送風装置１ｂにおける制御を示すフローチャートである。 The control performed by the blower device 1b according to the second modified example will be described with reference to FIG. 12. FIG. 12 is a flowchart showing the control performed by the blower device 1b according to the second modified example.
　第２の変形例に係る送風装置１ｂは、制御部５０ｂが現在の季節が冬期であることを示す信号を受け付けた場合に、利用者１００の着座部１３における着座位置によらず、４つの吹出ノズル１４のうちの両端に位置する２つの吹出ノズル１４から選択的に空気を送風する第３送風モードを有する点で第１の実施の形態に係る送風装置１と異なる。以下、第１の実施の形態で説明済みの内容は再度の説明を適宜省略し、第１の実施の形態と異なる点を主に説明する。 The blower device 1b according to the second modified example differs from the blower device 1 according to the first embodiment in that it has a third blowing mode in which, when the control unit 50b receives a signal indicating that the current season is winter, air is selectively blown from two of the four blowing nozzles 14 located at both ends, regardless of the seating position of the user 100 in the seating section 13. Below, the contents already explained in the first embodiment will not be explained again as appropriate, and the differences from the first embodiment will be mainly explained.
　第２の変形例に係る送風装置１ｂの制御部５０ｂ（図８の制御部５０と同様の構成）は、第１送風モードと、第２送風モードと、第３送風モードと、を切り替えて送風運転を行うものである。 The control unit 50b (similar in configuration to the control unit 50 in FIG. 8) of the blower device 1b in the second modified example performs blowing operation by switching between the first blowing mode, the second blowing mode, and the third blowing mode.
　ここで、第１送風モードおよび第２送風モードは、上述した第１の実施の形態に記載したものと同一である。つまり、第１送風モードでは、送風機２０が第１吹出ノズル１６および第２吹出ノズル１７へ送風を行い、第２送風モードでは、送風機２０が第２吹出ノズル１７のみに選択的に送風する。 Here, the first and second air blowing modes are the same as those described in the first embodiment above. That is, in the first air blowing mode, the blower 20 blows air to the first blowing nozzle 16 and the second blowing nozzle 17, and in the second air blowing mode, the blower 20 selectively blows air only to the second blowing nozzle 17.
　第３送風モードは、制御部５０ｂが現在の季節が冬期であることを示す信号を受け付けた場合に、利用者１００の着座部１３における着座位置によらず、４つの吹出ノズル１４のうちの両端に位置する２つの吹出ノズル１４（吹出ノズル１４ａおよび吹出ノズル１４ｄ）から選択的に空気を送風する。 In the third airflow mode, when the control unit 50b receives a signal indicating that the current season is winter, air is selectively blown from the two airflow nozzles 14 (airflow nozzle 14a and airflow nozzle 14d) located at both ends of the four airflow nozzles 14, regardless of the user's 100 seated position in the seating section 13.
　第３送風モードもまた、４つの吹出ノズル１４のうちの両端の吹出ノズル１４を使って送風するモードであり、部分気流モードとも言える。なお、第３送風モードは、吹出ノズル１４が４つであるため、利用者１００がブース２の中央に着座する場合に送風装置１が行う第２送風モードと実質的に同じ送風状態となる。 The third airflow mode also uses the two end blowing nozzles 14 out of the four blowing nozzles 14 to blow air, and can also be considered a partial airflow mode. Note that since there are four blowing nozzles 14 in the third airflow mode, the airflow state is essentially the same as the second airflow mode performed by the blower device 1 when the user 100 is seated in the center of the booth 2.
　［１．第２の変形例の構成］
　第２の変形例に係る送風装置１ｂにおける制御部５０ｂは、今の季節（例えば夏期、中間期（春期、秋期）、または冬期）を判定して、季節が冬期であると特定した場合に、第３送風モードでの送風運転を実行する。 [1. Configuration of the second modified example]
The control unit 50b in the blower device 1b according to the second modified example determines the current season (e.g., summer, mid-season (spring, autumn), or winter), and if it determines that the season is winter, performs blowing operation in the third blowing mode.
　より詳細には、第２の変形例に係る送風装置１ｂは、季節が冬期であると判定した場合、居室空間３ａ内に４つ配置される吹出ノズル１４のうち、両端に位置する２つの吹出ノズル１４のみに送風を行う第３送風モードを実行する。 More specifically, when the air blower device 1b according to the second modified example determines that the season is winter, it executes a third air blowing mode in which air is blown only through the two air blowing nozzles 14 located at both ends of the four air blowing nozzles 14 arranged in the living space 3a.
　例えば、吹出ノズル１４が４つの場合では、制御部５０ｂは、両端に位置する吹出ノズル１４ａと吹出ノズル１４ｄとから空気を吹き出すように、送風機２０ａと送風機２０ｄとに送風運転を行わせる。 For example, if there are four blowing nozzles 14, the control unit 50b controls the blowers 20a and 20d to perform blowing operation so that air is blown out from the blowing nozzles 14a and 14d located at both ends.
　つまり、第３送風モードでは、季節が冬期であると判定された場合、利用者１００の着座位置に関わらず、４つの吹出ノズル１４のうちの両端に位置する２つの吹出ノズル１４に向けて、給気口２１から吸い込んだ空気を送風する運転が実行される。 In other words, in the third airflow mode, if it is determined that the season is winter, the airflow is sucked in through the air intake port 21 and directed toward the two airflow nozzles 14 located at both ends of the four airflow nozzles 14, regardless of the seating position of the user 100.
　なお、制御部５０ｂによる季節判定は、季節を判定できる方法であればよく、検知手段を併用してもよい。例えば、気温を検知できる温度センサ（図示せず）をブース２内の給気空気の温度を判定できる場所（給気口２１または居室空間３ａ内等）に設けて、ブース２内の温度から季節を判定してもよいし、温度センサをブース２外の壁面等に設けて、ブース２が設置された空間の気温から季節を判定してもよい。 The season determination by the control unit 50b may be performed by any method that can determine the season, and a detection means may be used in combination. For example, a temperature sensor (not shown) that can detect the air temperature may be provided in a location where the temperature of the intake air in the booth 2 can be determined (such as the air intake port 21 or in the living space 3a), and the season may be determined from the temperature inside the booth 2, or a temperature sensor may be provided on a wall outside the booth 2, and the season may be determined from the air temperature in the space in which the booth 2 is installed.
　また、制御部５０ｂの処理部５４が、設定された日付情報から記憶部５２に記憶されたカレンダー情報を参照し、日付情報から季節判定を行うようにしてもよい。 The processing unit 54 of the control unit 50b may also refer to the calendar information stored in the memory unit 52 based on the set date information and determine the season based on the date information.
　また、居室空間３ａ内に、温湿度センサ、風速センサ、およびカメラのうち少なくともいずれか等を設置することで、居室空間３ａ内の環境、利用者１００の着衣量または活動量から、利用者１００のＰＭＶ（Ｐｒｅｄｉｃｔｅｄ　Ｍｅａｎ　Ｖｏｔｅ：予測平均温冷感申告）を演算し、季節を判定してもよい。 In addition, by installing at least one of a temperature and humidity sensor, a wind speed sensor, and a camera in the living space 3a, the PMV (Predicted Mean Vote) of the user 100 can be calculated based on the environment in the living space 3a and the amount of clothing or activity of the user 100, and the season can be determined.
　また、他機器の運転情報から季節情報を取得できるようにしてもよい。例えば、空気調和機等との連動である。詳細には、ブース２が設置される空間と同じ空間内に、暖房機能と冷房機能とを備えた空気調和機が設置されている場合、空気調和機の運転モード（冷房運転モード、暖房運転モード、または運転オフ）を取得して、季節を判定してもよい。 Furthermore, it may be possible to acquire seasonal information from the operation information of other devices. For example, linkage with an air conditioner or the like. In detail, if an air conditioner with heating and cooling functions is installed in the same space as the space in which booth 2 is installed, the operation mode of the air conditioner (cooling operation mode, heating operation mode, or operation off) may be acquired to determine the season.
　［２．第２の変形例の送風運転制御］
　第２の変形例に係る送風装置１ｂで行われる送風機２０の送風動作制御について、図１２を参照しながら説明する。ここで、第１の実施の形態の制御部５０および第１の変形例の制御部５０ａでは、制御ブロック図とともに送風動作制御を説明してきたが、第２の変形例においては、制御部５０ｂの制御ブロックは制御部５０、５０ａと共通であるため、説明を省略する。 [2. Fan operation control according to the second modified example]
The blowing operation control of blower 20 performed in blower device 1b according to the second modification will be described with reference to Fig. 12. Here, the blowing operation control has been described with reference to the control block diagrams for control unit 50 of the first embodiment and control unit 50a of the first modification, but in the second modification, the control block of control unit 50b is common to control units 50 and 50a, and therefore description thereof will be omitted.
　図１２に示すように、第２の変形例における送風装置１ｂの送風運転が開始されると、操作パネル４０等で設定された日付情報、温度センサまたは空気調和機の運転モード情報等から季節情報が取得される（Ｓ２１）。 As shown in FIG. 12, when the blowing operation of the blower device 1b in the second modified example is started, seasonal information is acquired from date information set on the operation panel 40 or the like, the temperature sensor or the operating mode information of the air conditioner, etc. (S21).
　そして取得された季節情報から、制御部５０ｂは、季節が冬期か否かを判定する（Ｓ２２）。 Then, based on the acquired seasonal information, the control unit 50b determines whether the season is winter or not (S22).
　ステップＳ２２での判定の結果、季節が冬期であると判定された場合（Ｓ２２のＹｅｓ）には、制御部５０ｂは、季節を冬期として特定し（Ｓ２３）、送風機２０を第３送風モードにて動作することを決定する（Ｓ２４）。 If the result of the determination in step S22 is that the season is winter (Yes in S22), the control unit 50b identifies the season as winter (S23) and determines to operate the blower 20 in the third blowing mode (S24).
　第３送風モードでの動作が決定されると、制御部５０ｂは、４つの吹出ノズル１４のうち、両端に位置する２つの吹出ノズル１４ａ、１４ｄに送風を行う２つの送風機２０ａ、２０ｄを作動させる（Ｓ２５）。 When operation in the third air blowing mode is determined, the control unit 50b activates the two blowers 20a, 20d that blow air to the two air blowing nozzles 14a, 14d located at both ends of the four air blowing nozzles 14 (S25).
　一方で、ステップＳ２２の判定の結果、季節が冬期ではないと判定された場合（Ｓ２２のＮｏ）、つまり、季節が中間期または夏期であると特定された場合（Ｓ２６）には、制御部５０ｂは、操作パネル４０からの入力情報を参照し、第１送風モードまたは第２送風モードでの動作を決定する（Ｓ２７）。 On the other hand, if the result of the judgment in step S22 is that the season is not winter (No in S22), that is, if the season is identified as mid-season or summer (S26), the control unit 50b refers to the input information from the operation panel 40 and decides whether to operate in the first airflow mode or the second airflow mode (S27).
　具体的には、制御部５０ｂは、第１の実施の形態における制御部５０が行うステップＳ０１からステップＳ０４ａまたはステップＳ０４ｂまでを実行する（図９参照）。 Specifically, the control unit 50b executes steps S01 to S04a or S04b that are performed by the control unit 50 in the first embodiment (see FIG. 9).
　制御部５０ｂは、決定した送風モードに応じて、送風機２０の送風動作を実行する（Ｓ２８）。具体的には、第１の実施の形態における制御部５０が行うステップＳ０５ａまたはステップＳ０５ｂを実行する（図９参照）。 The control unit 50b executes the blowing operation of the blower 20 according to the determined blowing mode (S28). Specifically, it executes step S05a or step S05b that is executed by the control unit 50 in the first embodiment (see FIG. 9).
　その後、制御部５０ｂは、ステップＳ２５またはステップＳ２８において、送風機２０による送風運転の開始時間を起点として計測された時間が、所定時間を経過したか否かの判定を行う（Ｓ２９）。ここで、所定時間は、例えば、１分に設定される。 Then, the control unit 50b determines whether the time measured from the start time of the blowing operation by the blower 20 in step S25 or step S28 has elapsed a predetermined time (S29). Here, the predetermined time is set to, for example, one minute.
　制御部５０ｂは、ステップＳ２９での判定の結果、所定時間が経過していない場合には（Ｓ２９のＮｏ）、送風機２０による送風運転動作をそのまま継続させる（Ｓ２９に戻る）。 If the result of the determination in step S29 is that the predetermined time has not elapsed (No in S29), the control unit 50b continues the blowing operation of the blower 20 (return to S29).
　また、制御部５０ｂは、ステップＳ２９において、所定時間が経過したと判定した場合には（Ｓ２９のＹｅｓ）、ステップＳ３０に移行する。 If the control unit 50b determines in step S29 that the predetermined time has elapsed (Yes in S29), the control unit 50b proceeds to step S30.
　ステップＳ３０では、送風装置１ｂの運転停止信号が入力されたか否かが判定される。送風装置１ｂの運転停止信号が入力されていなければ（Ｓ３０のＮｏ）、ステップＳ２１に戻り、送風装置１ｂの運転の実行が継続される。この際、計測した時間はリセットされる。 In step S30, it is determined whether or not a signal to stop operation of the blower device 1b has been input. If a signal to stop operation of the blower device 1b has not been input (No in S30), the process returns to step S21, and operation of the blower device 1b continues. At this time, the measured time is reset.
　一方で、ステップＳ２９での判定の結果、所定時間が経過し（Ｓ２９のＹｅｓ）、運転停止信号が入力された場合（Ｓ３０のＹｅｓ）には、ステップＳ３１に移行し、送風装置１ｂは、送風機２０を停止させ、運転終了状態または待機状態となる。ここで、送風装置１ｂは、所定時間経過を待たずに、運転停止信号を受け付けた場合には直ちに送風運転を停止することも可能である。 On the other hand, if the result of the determination in step S29 is that the predetermined time has elapsed (Yes in S29) and an operation stop signal has been input (Yes in S30), the process proceeds to step S31, where the blower device 1b stops the blower 20 and goes into an operation end state or standby state. Here, the blower device 1b can also stop the blowing operation immediately if it receives an operation stop signal without waiting for the predetermined time to elapse.
　以上のようにして、第２の変形例における送風装置１ｂは、季節情報を取得して季節判定を行い、季節判定の結果に対応して送風機２０の送風動作を制御して、第１送風モード、第２送風モード、および第３送風モードの切り替え動作を実行することができる。 In this way, the blower device 1b in the second modified example can acquire seasonal information, determine the season, control the blowing operation of the blower 20 in accordance with the result of the seasonal determination, and perform switching between the first blowing mode, the second blowing mode, and the third blowing mode.
　以上、第２の変形例に係る送風装置１ｂによれば、上述した効果（１）および効果（２）とともに、以下の効果を享受することができる。 As described above, according to the blower device 1b of the second modified example, in addition to the above-mentioned effects (1) and (2), the following effects can be obtained.
　（４）送風装置１ｂでは、制御部５０ｂは、季節が冬期であることを示す信号を受け付けた場合には、利用者１００の着座部１３における着座位置によらず、４つの吹出ノズル１４のうちの両端に位置する２つの吹出ノズル１４（吹出ノズル１４ａおよび吹出ノズル１４ｄ）に向けて、給気口２１から吸い込んだ空気を送風する第３送風モードに切り替えて複数の送風機２０を制御するようにした。 (4) In the blower device 1b, when the control unit 50b receives a signal indicating that the season is winter, the control unit 50b controls the multiple blowers 20 to switch to a third blowing mode in which air drawn in from the air intake 21 is blown toward the two blowing nozzles 14 (blowout nozzle 14a and blowout nozzle 14d) located at both ends of the four blowing nozzles 14, regardless of the user's 100 seated position in the seating area 13.
　これにより、冬期において、居室空間３ａの利用者１００が意図的に第２送風モードに切り替える手間がなくなり、利用者１００に気流が当たって利用者１００が寒く感じてしまうことが抑制されるので、利用者１００を居室空間３ａ内において快適に過ごさせることができる。 This eliminates the need for the user 100 in the living space 3a to intentionally switch to the second airflow mode during the winter, and prevents the user 100 from feeling cold due to the airflow hitting the user 100, allowing the user 100 to stay comfortable in the living space 3a.
　以上、本開示に関して実施の形態および変形例をもとに説明した。これらの実施の形態および変形例は例示であり、これらの各構成要素または各処理プロセスの組合せにはいろいろな変形例が可能なこと、またそうした変形例も本開示の範囲にあることは当業者に理解されるところである。 The above describes the present disclosure based on embodiments and modifications. These embodiments and modifications are merely examples, and it will be understood by those skilled in the art that various modifications are possible in the combination of each of these components or each of the processing processes, and that such modifications are also within the scope of the present disclosure.
　なお、第１の実施の形態に係る送風装置１では、４つの吹出ノズル１４を用いて説明したが、これに限られない。５つ以上の吹出ノズルであってもよい。 In the first embodiment, the blower device 1 is described using four blowing nozzles 14, but this is not limited to this. Five or more blowing nozzles may also be used.
　また、第１の実施の形態に係る送風装置では、居室空間３ａは、個人が滞在可能な狭小の空間としたが、これに限定されない。例えば、居室空間３ａは、個室ブースに限らず複数人が滞在可能な会議室等であってもよい。 In addition, in the blower device according to the first embodiment, the living space 3a is a small space where an individual can stay, but this is not limited to this. For example, the living space 3a is not limited to a private booth, but may be a conference room where multiple people can stay.
　また、本実施の形態に係る送風装置では、ブース２がボックス形状の空間であるとして説明したが、トップボード６を取り払った天井の無い半個室空間でもよい。また、扉１１およびサイドパネル５ａ、サイドパネル５ｂ、またはサイドパネル５ｄを取り払い、入退室用の扉がなくブース２の正面または側方から自由に出入りできる半個室空間でもよい。利用者１００の正面の壁（サイドパネル５ｄ）を取り払う場合、机１２は、着座部１３に着座して使用できる場所に配置されればよく、側方の壁によって支えられる形状、または居室空間３ａ内に独立して設置される形態（可搬式のテーブル等）に変形することもできる。 In addition, in the blower device according to this embodiment, the booth 2 has been described as being a box-shaped space, but it may be a semi-private space with no ceiling when the top board 6 is removed. Also, it may be a semi-private space with no door for entering or exiting and where people can freely enter or exit from the front or side of the booth 2 by removing the door 11 and the side panel 5a, 5b, or 5d. When the wall in front of the user 100 (side panel 5d) is removed, the desk 12 only needs to be placed in a place where it can be used by sitting on the seat 13, and it may be transformed into a shape supported by a side wall or a form that can be installed independently within the living space 3a (such as a portable table).
　本開示に係る送風装置は、送風をする際に送風する吹出ノズルを切り替えることで、居室空間内の換気をする際に、快適性を保ちながら送風することを可能とするものであるので、個人が滞在可能な狭小の居室空間等に設置する送風装置等として有用である。 The air blower according to the present disclosure is capable of blowing air while maintaining comfort when ventilating a room by switching the blowing nozzle used to blow air, and is therefore useful as an air blower to be installed in small rooms where individuals can stay.
