Description

本発明は、空気調和の対象となる室内空間における天井等に配置され、室内空間に対し調和空気を吹出す吹出口装置に関する。 TECHNICAL FIELD The present invention relates to an air outlet device that is arranged on a ceiling or the like in an indoor space to be air-conditioned and that blows conditioned air into the indoor space.

空気調和の対象となる室内空間のうち、熱が出入りしやすいなど外部環境の影響を受ける建物外周部、すなわち、外壁や窓、出入口など、の近傍の領域(ペリメータゾーン)においては、より内側の空間領域(インテリアゾーン)の空気調和を分離して、熱負荷の軽減を図るために、外壁や窓を内側から覆うようにカーテン状の空気流を生じさせ、外部からインテリアゾーンを熱的に分断することが従来から一般的に行われている。 Of the indoor spaces subject to air conditioning, the perimeter zone of the building, which is affected by the external environment, i.e., the outer walls, windows, doorways, etc., should be more inside. In order to separate the air conditioning of the space area (interior zone) and reduce the heat load, a curtain-like air flow is generated to cover the outer wall and windows from the inside, thermally separating the interior zone from the outside. It has been common practice to do so.

こうしたカーテン状の空気流を生じさせる装置としては、ライン型の吹出口装置を採用することが多かった。ライン型の吹出口装置は、細長い線状の開口部を備えることで、吹出気流を開口部形状に対応させて比較的狭い領域に集中させることができた。 As a device for generating such a curtain-like air flow, a line-type outlet device was often adopted. The line-type blower outlet device has an elongated linear opening, so that the blowing airflow can be concentrated in a relatively narrow area corresponding to the shape of the opening.

また、ライン型の吹出口装置は、室内空間のインテリアゾーンにも用いられることがあり、特に、室内空間の天井部がシステム天井の場合、天井のデザインに適合し、吹出口装置としての占有スペースが小さく設置性に優れるライン型の吹出口装置が広く採用されていた。
このような従来のライン型の吹出口装置の一例として、特開2001-272093号公報に記載されるものがある。
In addition, line-type air outlet devices are sometimes used in the interior zone of the indoor space, and in particular, when the ceiling of the indoor space is a system ceiling, Line-type outlet devices were widely used because of their small size and excellent ease of installation.
An example of such a conventional line-type outlet device is disclosed in Japanese Patent Laid-Open No. 2001-272093.

特開2001-272093号公報JP-A-2001-272093

前記特許文献1に示されるような従来のライン型の吹出口装置は、室内空間のインテリアゾーンに多用される多層コーン型の吹出口装置とは異なり、ダクトから吹出口に導入された調和空気の速度を落とさずに室内空間に吹出して、調和空気の気流を直進させることから、ペリメータゾーンでの使用には都合がよい。しかしながら、インテリアゾーンへの適用に際しては、室内空間で吹出気流が直進しやすいことから、居住域でドラフトが生じやすいという問題があった。 The conventional line-type air outlet device as shown in the above-mentioned Patent Document 1 is different from the multi-layered cone-type air outlet device that is frequently used in the interior zone of the indoor space, and the conditioned air introduced from the duct to the air outlet is It is convenient for use in the perimeter zone because it blows out into the indoor space without slowing down the flow of the conditioned air. However, when it is applied to the interior zone, there is a problem that drafts are likely to occur in the living area because the blowing air current tends to go straight in the interior space.

また、従来のライン型の吹出口装置の場合、吹出口の長手方向に吹出気流を進行させることが困難であることから、室内空間の広い範囲に調和空気を吹出すことができず、室内空間で吹出気流が室内空気を誘引しながら広く拡散する効率は多層コーン型の吹出口より劣り、その分、多数の吹出口を設置する必要があり、システム天井以外で、インテリアゾーンに設置する吹出口として積極的に採用されることは少ないという課題を有していた。 In addition, in the case of the conventional line-type air outlet device, it is difficult to advance the airflow in the longitudinal direction of the air outlet, so the conditioned air cannot be blown out over a wide area of the indoor space. The efficiency with which the airflow is diffused widely while attracting the indoor air is inferior to that of the multi-layered cone type outlet, so it is necessary to install a large number of outlets. There was a problem that it was rarely actively adopted as a

本発明は前記課題を解消するためになされたもので、細長いライン型の吹出口形態を有しつつ、調和空気の気流の進行方向を、吹出口長手方向を含む各方向に設定でき、吹出気流を室内空間に広く拡散させられ、インテリアゾーンにも適用しやすい吹出口装置を提供することを目的とする。 SUMMARY OF THE INVENTION The present invention has been made to solve the above problems. To provide an air outlet device capable of widely diffusing air in an indoor space and easily applicable to an interior zone.

本発明に係る吹出口装置は、空気調和対象の室内空間における天井又は壁に配設され、室内空間に調和空気を吹出す吹出口装置において、調和空気が通過可能な細長い矩形開口断面の開口部を取囲んだ略枠状体として形成され、天井内でダクトと接続されて調和空気を供給され、前記開口部から調和空気を室内空間へ吹出す吹出口本体と、前記吹出口本体の開口部に当該開口部の長手方向に一列に並べて複数配設され、調和空気の吹出す方向を所定の向きに案内する気流案内部と、前記吹出口本体の開口部を覆う大きさの略板状体で形成され、調和空気を通過させる通風孔を複数並べて穿設され、吹出口本体の開口部における室内空間側の端部に配設される化粧グリルとを備え、前記気流案内部が、矩形又は方形の開口を有する枠状体で形成される案内枠と、当該案内枠内側の開口に傾斜状態で且つ同じ向きに所定間隔を空けて並ぶ状態で複数配設される案内羽根とを有し、当該案内羽根の並ぶ向きを案内枠の各枠辺方向に対し斜交する方向とされてなり、前記吹出口本体の開口部で各気流案内部に案内されて吹出された調和空気の各気流が、相互に影響を及ぼし合い、一又は複数の合成気流として室内空間を進むものである。 The air outlet device according to the present invention is an air outlet device that is arranged on the ceiling or wall of an indoor space to be air-conditioned and that blows out conditioned air into the indoor space. an air outlet body formed as a substantially frame-shaped body surrounding a ceiling, connected to a duct in the ceiling to supply conditioned air, and blowing the conditioned air from the opening into the indoor space; and an opening of the air outlet body a plurality of airflow guide parts arranged in a row in the longitudinal direction of the opening and guiding the blowing direction of the conditioned air in a predetermined direction; and a decorative grill provided at the end of the opening of the outlet body on the indoor space side, wherein the airflow guide portion is rectangular or A guide frame formed of a frame-shaped body having a square opening, and a plurality of guide vanes arranged in a state of being inclined in the opening inside the guide frame and arranged in the same direction at predetermined intervals, The direction in which the guide vanes are arranged is set in a direction oblique to the direction of each frame side of the guide frame, and each air flow of the conditioned air blown out by being guided by each air flow guide part at the opening of the outlet main body is , influence each other and travel through the interior space as one or more combined airflows.

このように本発明によれば、天井に設けられる吹出口本体の細長い矩形状の開口部に、複数の気流案内部を並べて配設し、吹出口本体に流入した調和空気を、開口部の各気流案内部で案内して吹出し、気流案内部での案内方向の設定に基づいて吹出された各気流が互いに影響を与え合い、結果生じた合成気流が室内空間を進行して室内空間に拡散することにより、気流案内部での案内方向を適切に設定し、室内空間の所望の箇所に吹出口からの合成気流を進行させて、調和空気の気流を室内空間へ広く拡散させることができ、インテリアゾーンにおける空気調和を効率よく行え、空気調和のコストを抑制できる。また、吹出口を外壁又は窓に近いペリメータゾーンに設ける場合でも、問題なく気流をペリメータゾーンの外壁又は窓に到達させられ、室内空間各部で統一した吹出口とすることができ、吹出口設置に係るコストを抑えられると共に、室内空間の美観を向上させられる。さらに、調和空気の気流を気流案内部で案内してその進行方向を制御することで、気流が直進して下方の居住域に到達することを防止でき、居住域にドラフトなどの影響を与えずに空気調和を行うことができる。 As described above, according to the present invention, a plurality of airflow guides are arranged side by side in the elongated rectangular opening of the air outlet main body provided in the ceiling, and the conditioned air that has flowed into the air outlet main body is directed to each of the openings. The air currents are guided and blown out by the air current guide part, and each air current blown out based on the setting of the guide direction in the air current guide part influences each other, and the resulting synthetic air current advances in the indoor space and diffuses into the indoor space. Thus, the direction of guidance in the airflow guide section can be appropriately set, and the combined airflow from the outlet can be advanced to a desired location in the indoor space, so that the airflow of the conditioned air can be diffused widely in the indoor space. Air conditioning in the zone can be efficiently performed, and the cost of air conditioning can be suppressed. In addition, even when the air outlet is provided in the perimeter zone near the outer wall or window, the airflow can reach the outer wall or window of the perimeter zone without problems, and the air outlet can be unified in each part of the indoor space. The cost can be suppressed and the aesthetic appearance of the indoor space can be improved. Furthermore, by guiding the airflow of the conditioned air with the airflow guide and controlling its direction of movement, it is possible to prevent the airflow from traveling straight and reaching the lower living area, thus preventing drafts and other effects on the living area. can be air-conditioned.

また、本発明に係る吹出口装置は必要に応じて、前記気流案内部が、複数の組に分けられ、各組ごとに調和空気を案内して吹出す向きを異ならせるよう、前記吹出口本体の開口部に配設されるものである。 Further, in the blower outlet device according to the present invention, the airflow guide part is divided into a plurality of groups as needed, and the outlet main body is arranged such that each group guides the conditioned air in a different blowing direction. is arranged in the opening of the

このように本発明によれば、複数の気流案内部を調和空気の吹出方向が異なる複数組に分け、この気流案内部の組ごとの吹出方向を適切に設定することにより、各気流案内部から吹出された気流相互の影響の度合いを大きくすることができ、室内空間に対し、合成気流を所望の一又は複数方向へ進めて、調和空気を室内空間の所望の箇所に到達させられ、空気調和の効率をさらに高められる。 As described above, according to the present invention, by dividing a plurality of airflow guide portions into a plurality of groups in which conditioned air is blown in different directions, and by appropriately setting the blowout direction for each set of the airflow guide portions, each airflow guide portion can The degree of mutual influence of the blown air currents can be increased, and the combined air current can be advanced in one or more desired directions in the indoor space to allow the conditioned air to reach a desired location in the indoor space. can further increase the efficiency of

また、本発明に係る吹出口装置は必要に応じて、前記気流案内部が、隣り合う各気流案内部同士で、調和空気を案内して吹出す向きを異ならせて、合成気流の進行方向を、気流案内部ごとの吹出方向とは異なる向きとなるように、前記吹出口本体の開口部にそれぞれ配設されるものである。 Further, in the blower outlet device according to the present invention, the airflow guide portions guide and blow out the conditioned air in different directions between adjacent airflow guide portions as necessary, so that the traveling direction of the combined airflow is controlled. , are disposed in the openings of the outlet main body so as to be different from the blowing direction of each airflow guide.

このように本発明によれば、吹出口本体開口部の各気流案内部における調和空気の吹出方向を隣り合う各気流案内部同士で異なるようにし、各気流案内部から吹出された気流が互いに大きな影響を及ぼす状態として、調和空気の合成気流を各気流案内部ごとの吹出方向とは異なる向きに向かわせることにより、調和空気の気流が直進せず速度を落とした状態の合成気流として室内空間を進むこととなり、多層コーン型の吹出口のような拡散性に優れた気流として室内空間各部に到達させられ、従来のライン型の吹出口による吹出では得られない空気調和状態を実現でき、室内空間に対する空気調和をより効率よく実行できると共に、調和空気が複数の速度成分を有して直進しないことで、居住域におけるドラフトを確実に防止できる。 Thus, according to the present invention, the direction in which the conditioned air is blown out from each airflow guide portion of the air outlet main body opening is made different between the adjacent airflow guide portions so that the airflows blown out from the respective airflow guide portions are larger than each other. As a state that affects, by directing the synthetic airflow of the conditioned air in a direction different from the blowing direction of each airflow guide part, the indoor space is filled with the synthetic airflow in a state where the airflow of the conditioned air does not go straight and the speed is reduced. As it advances, it reaches various parts of the indoor space as an airflow with excellent diffusibility like a multi-layered cone type outlet, realizing an air conditioning state that cannot be obtained with blowing from a conventional line type outlet. Air conditioning can be performed more efficiently, and the conditioned air has a plurality of velocity components and does not travel straight, so that drafts in the living area can be reliably prevented.

また、本発明に係る吹出口装置は必要に応じて、前記化粧グリルの室内空間に面する部分が、格子状に形成され、前記気流案内部の案内枠における他の気流案内部と隣り合う枠辺部位が、前記化粧グリルの格子状部分と重ねて配設されるものである。 Further, in the air outlet device according to the present invention, the portion of the decorative grille facing the indoor space is formed in a lattice shape, and is adjacent to another airflow guide portion in the guide frame of the airflow guide portion. The side portions are arranged so as to overlap with the lattice-like portion of the decorative grill.

このように本発明によれば、化粧グリルの室内空間に面する部分を格子状とし、この化粧グリルの格子状部分に、各気流案内部の隣接する枠辺部位が重なるように気流案内部を配設して、気流案内部の案内枠に囲まれた案内羽根のある開口領域に、化粧グリルの格子状部分が重なる割合を小さくすることにより、各気流案内部の案内羽根のある開口領域から調和空気が吹出す際の圧力損失や騒音を低減でき、調和空気を室内空間にスムーズに吹出して室内空間への拡散能力を向上させられ、空気調和をさらに効率よく行える。 As described above, according to the present invention, the portion of the decorative grille facing the indoor space is formed in a lattice shape, and the airflow guide portions are arranged so that the adjacent frame side portions of the respective airflow guide portions overlap with the lattice portion of the decorative grille. By reducing the overlapping ratio of the lattice-like portion of the decorative grille to the opening area with the guide vanes surrounded by the guide frame of the airflow guide part, the opening area with the guide vanes of each airflow guide part Pressure loss and noise when conditioned air is blown out can be reduced, conditioned air can be smoothly blown out into the indoor space, and the ability to diffuse the conditioned air into the indoor space can be improved, so that air conditioning can be performed more efficiently.

(本発明の第1の実施形態)
以下、本発明の第1の実施形態に係る吹出口装置を前記図1ないし図9に基づいて説明する。
(First embodiment of the present invention)
A blowout port device according to a first embodiment of the present invention will be described below with reference to FIGS. 1 to 9. FIG.

前記各図において本実施形態に係る吹出口装置1は、細長い矩形開口断面の開口部11を取囲んだ略枠状体として形成され、空気調和対象の室内空間70における天井50に配設される吹出口本体10と、この吹出口本体10の開口部11に並べて配設されて、調和空気の吹出す方向を所定の向きに案内する複数の気流案内部20と、吹出口本体10の開口部11を覆う大きさの略板状体で形成され、調和空気を通過可能として吹出口本体10の開口部11に配設される化粧グリル30とを備える構成である。 In each of the figures, the air outlet device 1 according to the present embodiment is formed as a substantially frame-shaped body surrounding an opening 11 having an elongated rectangular opening cross section, and is arranged on the ceiling 50 in the indoor space 70 to be air-conditioned. An air outlet main body 10, a plurality of airflow guides 20 arranged side by side in an opening 11 of the air outlet main body 10 to guide the blowing direction of the conditioned air in a predetermined direction, and an opening of the air outlet main body 10. 11, and a decorative grille 30 that is arranged in the opening 11 of the outlet main body 10 so that the conditioned air can pass through.

前記吹出口本体10は、調和空気の通過可能な細長い矩形開口断面の開口部11を取囲む、金属等の強度の高い材質製の略枠状体として形成され、天井50内に配設された調和空気供給用の公知のダクト51に、同じく公知の取付用フック等を用いて支持される構成である(図3参照)。 The air outlet main body 10 is formed as a substantially frame-shaped body made of a high-strength material such as metal, which surrounds the opening 11 having an elongated rectangular cross-section through which the conditioned air can pass, and is disposed in the ceiling 50. It is configured to be supported by a known duct 51 for supplying conditioned air using a similarly known mounting hook or the like (see FIG. 3).

この吹出口本体10は、天井50内でダクト51に支持されつつこのダクト51と接続されて調和空気を供給される。吹出口本体10では、供給された調和空気を、開口部11から各気流案内部20による案内を経て、室内空間70に吹出すこととなる。 The outlet main body 10 is supported by a duct 51 within the ceiling 50 and is connected to the duct 51 to be supplied with conditioned air. In the outlet main body 10 , the supplied conditioned air is blown out from the opening 11 into the indoor space 70 through the guidance of the airflow guides 20 .

また、吹出口本体10の室内空間側の端部には、開口部11に対する外側方向に突出する額縁部13が形成される構成である。この額縁部13は、内方の開口部11とは反対側となる外方へ所定幅突出する部分を周方向へ連続させて略鍔状とし、さらにその最外周部分を上方へ起立状態とした形状とされる構成である。 In addition, a frame portion 13 projecting outward with respect to the opening portion 11 is formed at the end portion of the air outlet main body 10 on the indoor space side. The frame portion 13 has a substantially brim-like portion that protrudes outward by a predetermined width on the opposite side of the inner opening portion 11 and is formed in a substantially brim shape by continuing in the circumferential direction, and further, the outermost peripheral portion thereof is in an upright state. It is a configuration made into a shape.

前記気流案内部20は、吹出口本体10の開口部11における室内空間寄り位置に、この開口部11の長手方向に一列に並べて複数配設される構成であり、調和空気の吹出す方向を所定の向きに案内するものである。 The airflow guide part 20 is arranged in a row in the longitudinal direction of the opening 11 of the air outlet main body 10 at a position closer to the indoor space. direction.

詳細には、気流案内部20は、方形の開口を有する枠状体で形成される案内枠21と、この案内枠21内側の開口に傾斜状態で且つ同じ向きに所定間隔を空けて平行に並ぶ状態で複数配設される略板状の案内羽根22とを有する構成である。気流案内部20における案内羽根22の並ぶ向きは、案内枠21の各枠辺方向に対し斜交する方向(例えば、枠辺方向に対し45°をなす方向)とされてなり、この案内羽根22同士の平行に並んだ向きが気流案内方向となる。 More specifically, the airflow guide part 20 is arranged in parallel with a guide frame 21 formed of a frame-like body having a square opening, with a predetermined interval in the same direction and in an inclined state with respect to the opening inside the guide frame 21 . It is a configuration having a plurality of substantially plate-shaped guide vanes 22 arranged in a state. The direction in which the guide vanes 22 are arranged in the airflow guide portion 20 is a direction oblique to each frame side direction of the guide frame 21 (for example, a direction forming an angle of 45° with respect to the frame side direction). The direction in which they are aligned parallel to each other is the airflow guiding direction.

気流案内部20の各案内羽根22は、細長い矩形状の薄板を、その長手方向に直交する断面形状が湾曲して全体に丸みを帯びた形状となるように形成されたものである。この案内羽根22が、方形枠状の案内枠21に長手方向両端部を固定され、案内枠21で囲まれる開口領域を横断する配置として、等間隔で平行に並べて複数配設される。 Each guide vane 22 of the airflow guide part 20 is formed by forming an elongated rectangular thin plate so that the cross-sectional shape orthogonal to the longitudinal direction thereof is curved to have a rounded shape as a whole. Both longitudinal ends of the guide vanes 22 are fixed to a rectangular guide frame 21, and a plurality of guide vanes 22 are arranged in parallel at regular intervals so as to traverse an opening area surrounded by the guide frame 21. As shown in FIG.

この気流案内部20は、案内羽根22間の空気通路部分に調和空気を通過させつつ、調和空気を案内羽根22の並んだ向きにそれぞれ案内することとなる。調和空気の気流は、吹出口全体では、各気流案内部20の案内羽根22間を通って室内空間に吹出された後、他の気流案内部から吹出された分と相互に影響を及ぼし合い、一又は複数の合成気流として室内空間を進むこととなる。 The airflow guide portion 20 guides the conditioned air in the direction in which the guide vanes 22 are arranged while allowing the conditioned air to pass through the air passage portion between the guide vanes 22 . After the airflow of the conditioned air is blown out into the indoor space through the guide vanes 22 of each airflow guide portion 20, the airflow of the conditioned air in the entire blowout port affects each other with the amount blown out from the other airflow guide portions, It will travel through the indoor space as one or more combined airflows.

このような気流案内部20は、開口部11に複数配設される状態で、複数の組に分けられ、各組ごとに調和空気を案内して吹出す向きを異ならせるようにされる。
さらにいえば、気流案内部20は、隣り合う各気流案内部同士で、案内羽根22の並ぶ向き、すなわち、調和空気を案内して吹出す向きを異ならせて、合成気流の進行方向を、気流案内部20ごとの吹出方向とは異なる向きとなるように、開口部11にそれぞれ配設される。
A plurality of such airflow guide portions 20 are arranged in the opening portion 11 and are divided into a plurality of sets so that the conditioned air is guided and blown in a different direction for each set.
Furthermore, the airflow guides 20 are arranged such that the directions in which the guide vanes 22 line up, i.e., the direction in which the conditioned air is guided and blown out, are different between the adjacent airflow guides, so that the traveling direction of the combined airflow is controlled by the airflow. They are arranged in the openings 11 so as to be different from the blowing direction of each guide part 20 .

各気流案内部20は対称な方形状となっており、その四辺と吹出口本体10の開口部11との位置関係は四通り得られる。これにより、吹出口本体10の開口部11において、各気流案内部20はその配設の向きを四通りの中から適宜選択して配設することができ、各気流案内部20の気流案内方向、すなわち、各気流案内部20での複数の案内羽根22の並ぶ向きは、90°ずつずれた四方向のいずれかに設定できる。この気流案内方向は、気流案内部20の組ごとに設定される。 Each airflow guide part 20 has a symmetrical rectangular shape, and four different positional relationships between the four sides and the opening 11 of the outlet main body 10 can be obtained. Accordingly, in the opening 11 of the outlet main body 10, each airflow guide portion 20 can be disposed by appropriately selecting its orientation from four directions. That is, the direction in which the plurality of guide vanes 22 are arranged in each airflow guide portion 20 can be set to any one of four directions shifted by 90°. This airflow guide direction is set for each set of airflow guide portions 20 .

例えば、図8に示すように、各気流案内部20を、その気流案内方向が吹出口本体10における開口部11の長手方向の一方と短手方向の一方との間の斜め方向D1となる組と、気流案内方向が開口部11の長手方向の一方と短手方向の他方との間の斜め方向D2となる組とに分け、これら二つの組が、開口部11の長手方向に一列に並ぶ気流案内部20で交互に入れ替わるように、すなわち、隣り合う各気流案内部20同士で、気流案内方向が異なるように配設することができる。
この場合、各気流案内部20から吹出された気流の合成気流は、各気流案内部20の気流案内方向とは異なる、開口部11の長手方向の一方へ斜め下向きに進む状態となる。
For example, as shown in FIG. 8, each airflow guide portion 20 is a group whose airflow guide direction is an oblique direction D1 between one longitudinal direction and one lateral direction of the opening 11 of the outlet main body 10. and a group in which the airflow guide direction is an oblique direction D2 between one of the longitudinal directions of the opening 11 and the other of the transverse directions, and these two groups are arranged in a line in the longitudinal direction of the opening 11. The airflow guide portions 20 can be arranged alternately, that is, adjacent airflow guide portions 20 can be arranged so that the airflow guide directions are different.
In this case, the combined airflow of the airflows blown out from the respective airflow guide portions 20 advances obliquely downward in one longitudinal direction of the opening 11, which is different from the airflow guiding direction of the respective airflow guide portions 20. FIG .

なお、各気流案内部20は、開口部11を長手方向に複数等分割した同じ大きさの方形状とされ、開口部11の長手方向と短手方向における各寸法を同じとして、開口部11への配設の向きを入れ替え可能に設定しているが、これに限られるものではなく、各気流案内部を同じ大きさとしつつも、開口部11の長手方向と短手方向における各寸法が異なる矩形状としたり、開口部11を長手方向に不等分割とした形状として、気流案内部ごとに大きさが異なるようにすることもできる。 Each airflow guide part 20 has a rectangular shape of the same size obtained by equally dividing the opening 11 in the longitudinal direction. However, it is not limited to this, and while each airflow guide portion has the same size, each dimension in the longitudinal direction and the lateral direction of the opening 11 is different. Alternatively, the opening 11 may be divided into unequal portions in the longitudinal direction so that each airflow guide portion has a different size.

また、気流案内部20は、吹出口本体10に対し着脱可能とし、室内空間における空気調和条件の変化に合わせて、必要に応じ各気流案内部20を組み替えてその気流案内方向の設定を変えるようにしてもかまわない。 In addition, the airflow guide part 20 is detachable from the outlet main body 10, and each airflow guide part 20 is rearranged as necessary to change the setting of the airflow guide direction in accordance with changes in the air conditioning conditions in the indoor space. It doesn't matter.

前記化粧グリル30は、吹出口本体10の開口部11を覆う大きさの略板状体で形成され、調和空気を無理なく通過させられる大きさの通風孔31を所定の規則的配置で複数並べて設けられ、吹出口本体10の開口部11における室内空間側の端部に配設される構成である。 The decorative grille 30 is formed of a substantially plate-like body sized to cover the opening 11 of the air outlet main body 10, and has a plurality of ventilation holes 31 sized to allow the conditioned air to pass without difficulty, arranged in a predetermined regular arrangement. It is provided at the end of the opening 11 of the outlet main body 10 on the indoor space side.

化粧グリル30の室内空間に面する部分は、格子状に形成されており、この化粧グリルの格子状部分に、各気流案内部20の案内枠21における他の気流案内部と隣り合う枠辺部位が重なるようにされる構成である。 A portion of the decorative grille 30 facing the interior space is formed in a lattice shape, and the frame side portion of the guide frame 21 of each airflow guide portion 20 adjacent to another airflow guide portion is formed in the lattice-like portion of the decorative grille 30 . are overlapped.

この化粧グリル30は、吹出口本体10の開口部11の室内空間側端部に配設されて、気流案内部20を覆う状態とされる一方、通風孔31の開口率を大きく設定されており、内側の気流案内部20を室内側から見えにくくしつつ、気流案内部20の案内羽根22で案内される調和空気の気流の吹出しに影響を与えることはない。 The decorative grille 30 is arranged at the end of the opening 11 of the outlet main body 10 on the side of the indoor space to cover the airflow guide section 20, while the opening ratio of the ventilation holes 31 is set to be large. 2. While making the inner airflow guide part 20 difficult to see from the inside of the room, it does not affect blowout of the airflow of the conditioned air guided by the guide vanes 22 of the airflow guide part 20.例文帳に追加

次に、前記構成に基づく吹出口装置における調和空気吹出状態について説明する。前提として、ダクト51を通じて吹出口装置1に対し調和空気が継続的に供給される状況にあるものとする。
ダクト51から供給された調和空気は、吹出口本体10内に進入すると、開口部11における室内空間寄りに位置する気流案内部20に到達する。
Next, the conditioned air blowing state in the blower outlet device based on the above configuration will be described. As a premise, it is assumed that conditioned air is continuously supplied to the outlet device 1 through the duct 51 .
When the conditioned air supplied from the duct 51 enters the outlet main body 10 , it reaches the airflow guide portion 20 positioned closer to the indoor space in the opening portion 11 .

気流案内部20に達した調和空気は、案内枠21内で並んだ各案内羽根22の間を進み、各案内羽根22に案内されて進行方向を変えた上で、化粧グリル30の通風孔31を経て、室内空間70に吹出す。 The conditioned air that has reached the airflow guide portion 20 advances between the guide vanes 22 arranged in the guide frame 21, is guided by the guide vanes 22 to change the traveling direction, and then flows through the ventilation holes 31 of the decorative grille 30. and blows out into the indoor space 70 .

この時、各気流案内部20のうち、気流案内部20での気流案内方向、すなわち、複数の案内羽根22の並ぶ向きが、吹出口11の長手方向の一方と短手方向の一方との間の斜め方向D1となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図8中で反時計回りに45°ずれた斜め方向D1へ、天井50に沿って水平に進もうとする(図8中、気流a)。 At this time, the direction of airflow guidance in each airflow guide portion 20, that is, the direction in which the plurality of guide vanes 22 are arranged is between one of the longitudinal directions and one of the lateral directions of the outlet 11. , the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and in the case of a single blowout that is not affected by the surroundings, one of the longitudinal directions of the blowout port 11 8, it tries to advance horizontally along the ceiling 50 in an oblique direction D1 shifted counterclockwise by 45° in FIG. 8 (airflow a in FIG. 8).

一方、気流案内部20での気流案内方向が吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図8中で時計回りに45°ずれた斜め方向D2へ、天井50に沿って水平に進もうとする(図8中、気流b)。 On the other hand, in a set in which the airflow guiding direction in the airflow guide portion 20 is the oblique direction D2 between one of the longitudinal directions of the outlet 11 and the other of the lateral directions, the conditioned air flowing between the guide vanes 22 is , Guided by the guide vanes 22, in the case of a single blowout that is not affected by the surroundings, from one of the longitudinal directions of the blowout port 11 to the ceiling 50 in an oblique direction D2 shifted clockwise by 45° in FIG. (airflow b in FIG. 8).

実際には、気流案内方向が斜め方向D1となる組の各気流案内部20から吹出される気流と、気流案内方向が斜め方向D2となる組の各気流案内部20から吹出される気流は、同時に生じていることから、互いに影響を及ぼし合って一つにまとまり、開口部11の長手方向への速度成分を残しつつ、その速度を低下させることで、天井に沿わない気流となる。 Actually, the airflow blown out from each airflow guide portion 20 of the set whose airflow guide direction is the oblique direction D1 and the airflow blown from each airflow guide portion 20 of the set whose airflow guide direction is the oblique direction D2 are Since they are generated at the same time, they influence each other and combine into one, leaving the velocity component in the longitudinal direction of the opening 11 and reducing its velocity, resulting in an airflow that does not follow the ceiling.

この一つにまとまった合成気流は、結果として、各気流案内部20の気流案内方向とは異なった、開口部11の長手方向の一方へ向かい、且つ、斜め下向きの気流(図9中、気流E)となって室内空間70を進行し、室内空間各部へ拡散していくこととなる(図9参照)。 As a result, the combined combined airflow is directed to one side of the longitudinal direction of the opening 11, which is different from the airflow guiding direction of each airflow guide portion 20, and is an obliquely downward airflow (in FIG. 9, the airflow E), it travels through the indoor space 70 and spreads to various parts of the indoor space (see FIG. 9).

こうして、調和空気の気流が、各気流案内部20の気流案内方向にそれぞれ案内されて、室内空間に吹出す中、気流同士が相互に影響を与えながら一まとまりの合成気流となって室内空間を進行することで、従来のライン型の吹出口では得にくい、吹出口長手方向への調和空気の気流を進行させて、室内空間で効率よく空気調和が行える。 In this way, the airflows of the conditioned air are each guided in the airflow guide direction of each airflow guide portion 20 and blown out into the indoor space. By proceeding, airflow of the conditioned air is advanced in the longitudinal direction of the outlet, which is difficult to achieve with the conventional line-type outlet, and air conditioning can be performed efficiently in the indoor space.

特に、暖房の場合には上昇しやすい調和空気の気流が過度に天井に沿ったものとならず、無理なく室内空間を進む気流とすることができる。また、冷房の場合には下降しやすい調和空気の気流が下方に下がりすぎることを防止でき、室内空間下方の居住域に調和空気を到達させずに済み、居住域に対しドラフトなどの悪影響を及ぼさない状態が確実に得られる。 In particular, in the case of heating, the airflow of conditioned air, which tends to rise, does not excessively flow along the ceiling, and the airflow can flow smoothly in the indoor space. In addition, in the case of cooling, it is possible to prevent the conditioned air, which tends to descend, from falling too far, preventing the conditioned air from reaching the living area in the lower part of the room, thereby preventing adverse effects such as drafts on the living area. You can definitely get a state without

このように、本実施形態に係る吹出口装置においては、天井50に設けられる吹出口本体10の細長い矩形状の開口部11に、複数の気流案内部20を並べて配設し、吹出口本体10に流入した調和空気を、開口部11の各気流案内部20で案内して吹出し、気流案内部20での案内方向の設定に基づいて吹出された各気流が互いに影響を与え合い、結果生じた合成気流が室内空間を進行して室内空間に拡散することから、気流案内部20での案内方向を適切に設定し、室内空間70の所望の箇所に吹出口からの合成気流を進行させて、調和空気の気流を室内空間へ広く拡散させることができ、インテリアゾーンにおける空気調和を効率よく行え、空気調和のコストを抑制できる。また、吹出口を外壁又は窓に近いペリメータゾーンに設ける場合でも、問題なく気流をペリメータゾーンの外壁又は窓に到達させられ、室内空間各部で統一した吹出口とすることができ、吹出口設置に係るコストを抑えられると共に、室内空間の美観を向上させられる。さらに、調和空気の気流を気流案内部20で案内してその進行方向を制御することで、気流が直進して下方の居住域に到達することを防止でき、居住域にドラフトなどの影響を与えずに空気調和を行うことができる。 As described above, in the blower outlet device according to the present embodiment, a plurality of airflow guide portions 20 are arranged side by side in the elongated rectangular opening 11 of the blower outlet main body 10 provided on the ceiling 50 . The conditioned air that has flowed into the opening 11 is guided by the airflow guides 20 of the opening 11 and blown out. Since the synthetic airflow advances in the indoor space and diffuses into the indoor space, the guiding direction of the airflow guide part 20 is appropriately set, and the synthetic airflow from the outlet is advanced to a desired location in the indoor space 70, The airflow of the conditioned air can be widely diffused into the indoor space, the air conditioning in the interior zone can be efficiently performed, and the cost of the air conditioning can be suppressed. In addition, even when the air outlet is provided in the perimeter zone near the outer wall or window, the airflow can reach the outer wall or window of the perimeter zone without problems, and the air outlet can be unified in each part of the indoor space. The cost can be suppressed and the aesthetic appearance of the indoor space can be improved. Furthermore, by guiding the airflow of the conditioned air by the airflow guide part 20 and controlling its advancing direction, it is possible to prevent the airflow from traveling straight and reaching the lower living area, and the living area will be affected by drafts and the like. Air conditioning can be done without

なお、前記実施形態に係る吹出口装置において、吹出口本体10の開口部11に気流案内部20を20個配設する構成としているが、これに限られるものではなく、室内空間への吹出口配置状況や吹出口から吹出す調和空気の風量や温度等の条件に基づいて選定される吹出口装置の大きさ、特に開口部の大きさ、に対応させて、適切な数の気流案内部を配設することができる。 In addition, in the outlet device according to the above-described embodiment, 20 airflow guide portions 20 are arranged in the opening 11 of the outlet main body 10, but the configuration is not limited to this, and the outlet to the indoor space is provided. An appropriate number of airflow guides are provided in accordance with the size of the air outlet device, especially the size of the opening, which is selected based on conditions such as the placement situation and the volume and temperature of the conditioned air blown from the air outlet. can be arranged.

また、前記実施形態に係る吹出口装置において、化粧グリル30の格子形状は、図1に示すような方形の通風孔31が一列に並んで、格子部分が各気流案内部20の枠辺部位と重なるもののみとして、吹出し時の圧力損失や騒音を抑える構成としているが、これに限らず、図10や図11に示すような、格子部分の一部が気流案内部の案内枠内の開口領域や案内羽根と重なるような格子形状であってもかまわない。 In addition, in the air outlet device according to the above-described embodiment, the lattice shape of the decorative grille 30 is such that square ventilation holes 31 are arranged in a row as shown in FIG. Only overlapping parts are used to suppress pressure loss and noise at the time of blowing, but not limited to this, as shown in FIGS. It may have a lattice shape overlapping with the guide vanes.

(本発明の第2の実施形態)
前記第1の実施形態に係る吹出口装置においては、各気流案内部20から吹出された気流の合成気流は所定の一方向に進むもののみとされる構成としているが、この他、第2の実施形態として、図12及び図13に示すように、各気流案内部20の気流案内方向の組合せを変えて、合成気流が二つの方向に進む二つの気流として得られる構成とすることもできる。
(Second embodiment of the present invention)
In the blower outlet device according to the first embodiment, the combined airflow of the airflows blown out from the respective airflow guide portions 20 is configured to proceed only in one predetermined direction. As an embodiment, as shown in FIGS. 12 and 13, by changing the combination of the airflow guiding directions of the respective airflow guide portions 20, the combined airflow can be obtained as two airflows traveling in two directions.

例えば、図12に示すように、吹出口11の中央から一端部寄りの部位では、各気流案内部20を、その気流案内方向が吹出口11の長手方向の一方と短手方向の一方との間の斜め方向D1となる組と、気流案内方向が吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となる組とに分ける。また、吹出口11の中央から他端部寄りの部位では、各気流案内部20を、その気流案内方向が吹出口11の長手方向の他方と短手方向の一方との間の斜め方向D3となる組と、気流案内方向が吹出口11の長手方向の他方と短手方向の他方との間の斜め方向D4となる組とに分ける。 For example, as shown in FIG. 12, at a portion closer to one end from the center of the blowout port 11, each airflow guide portion 20 is arranged so that the airflow guiding direction is one of the longitudinal directions of the blowout port 11 and the other of the widthwise directions. The group is divided into a group in which the airflow guide direction is an oblique direction D1 between them and a group in which the airflow guide direction is an oblique direction D2 between one of the longitudinal directions of the outlet 11 and the other of the lateral directions. In addition, at a portion near the other end from the center of the blowout port 11, each airflow guide portion 20 is arranged so that the airflow guide direction is the diagonal direction D3 between the other longitudinal direction and the one lateral direction of the blowout port 11. and a group whose airflow guide direction is an oblique direction D4 between the other longitudinal direction and the other lateral direction of the outlet 11 .

これら気流案内部の四つの組は、吹出口11の中央から一端部寄りの部位で一列に並ぶ気流案内部20において、各気流案内部20の気流案内方向を斜め方向D1とする組と、気流案内方向を斜め方向D2とする組とが交互に入れ替わり、且つ、吹出口11の中央から他端部寄りの部位で一列に並ぶ気流案内部20において、各気流案内部20の気流案内方向を斜め方向D3とする組と、気流案内方向を斜め方向D4とする組とが交互に入れ替わるように配設される。すなわち、隣り合う各気流案内部20同士で、気流案内方向が異なるように配設される。 These four sets of airflow guide portions are a set in which the airflow guide direction of each airflow guide portion 20 is a diagonal direction D1 in the airflow guide portions 20 aligned in a row near one end portion from the center of the blowout port 11, and an airflow The airflow guiding direction of each airflow guiding portion 20 is arranged diagonally in the airflow guiding portions 20 alternately arranged in a line near the other end portion from the center of the outlet 11. They are arranged so that the set in the direction D3 and the set in which the airflow guide direction is the oblique direction D4 are alternately arranged. That is, adjacent airflow guide portions 20 are arranged so that the airflow guide directions are different.

この場合、各気流案内部20から吹出された気流の合成気流は、長手方向の両方へ斜め下向きに進む状態となる。
具体的には、各気流案内部20のうち、気流案内部20での気流案内方向、すなわち、複数の案内羽根22の並ぶ向きが、吹出口11の長手方向の一方と短手方向の一方との間の斜め方向D1となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図12中で反時計回りに45°ずれた斜め方向D1へ、天井50に沿って水平に進もうとする(図12中、気流a)。
In this case, the combined airflow of the airflows blown out from the respective airflow guide portions 20 is in a state of traveling obliquely downward in both longitudinal directions.
Specifically, among the airflow guide portions 20, the airflow guide direction in the airflow guide portion 20, that is, the direction in which the plurality of guide vanes 22 are arranged, is one of the longitudinal direction and one of the lateral directions of the outlet 11. In the set that is in the oblique direction D1 between the guide vanes 22, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and if it is a single blowout that is not affected by the surroundings, the longitudinal direction of the blowout port 11 12 to the oblique direction D1 shifted counterclockwise by 45° in FIG. 12 and horizontally along the ceiling 50 (airflow a in FIG.

一方、気流案内部20での気流案内方向が、吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図12中で時計回りに45°ずれた斜め方向D2へ、天井50に沿って水平に進もうとする(図12中、気流b)。 On the other hand, in a pair in which the airflow guiding direction of the airflow guide portion 20 is the oblique direction D2 between one of the longitudinal directions of the outlet 11 and the other of the lateral directions thereof, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22. In the case of a single blowout that is not affected by the surroundings, from one of the longitudinal directions of the blowout port 11, in FIG. (airflow b in FIG. 12).

また、気流案内部20での気流案内方向が、吹出口11の長手方向の他方と短手方向の一方との間の斜め方向D3となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の他方から、図12中で時計回りに45°ずれた斜め方向D3へ、天井50に沿って水平に進もうとする(図12中、気流c)。 In addition, in a pair in which the airflow guiding direction in the airflow guide portion 20 is the oblique direction D3 between the other longitudinal direction and the one lateral direction of the outlet 11, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22. In the case of a single blowout that is not affected by the surroundings, from the other longitudinal direction of the blowout port 11, in FIG. (airflow c in FIG. 12).

さらに、気流案内部20での気流案内方向が、吹出口11の長手方向の他方と短手方向の他方との間の斜め方向D4となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の他方から、図12中で反時計回りに45°ずれた斜め方向D4へ、天井50に沿って水平に進もうとする(図12中、気流d)。 Furthermore, in a pair in which the airflow guiding direction in the airflow guide portion 20 is the oblique direction D4 between the other longitudinal direction and the other lateral direction of the outlet 11, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vane 22, and in the case of a single blowout that is not affected by the surroundings, the ceiling It tries to move horizontally along 50 (airflow d in FIG. 12).

実際には、気流案内方向が斜め方向D1となる組の各気流案内部20から吹出される気流と、気流案内方向が斜め方向D2となる組の各気流案内部20から吹出される気流は、同時に生じていることから、互いに影響を及ぼし合って一つにまとまり、開口部11の長手方向の一方への速度成分を残しつつ、その速度を低下させることで、天井に沿わない気流となる。 Actually, the airflow blown out from each airflow guide portion 20 of the set whose airflow guide direction is the oblique direction D1 and the airflow blown from each airflow guide portion 20 of the set whose airflow guide direction is the oblique direction D2 are Since they are generated at the same time, they influence each other and combine into one, leaving a velocity component in one of the longitudinal directions of the opening 11, and reducing the velocity to form an airflow that does not follow the ceiling.

また、気流案内方向が斜め方向D3となる組の各気流案内部20から吹出される気流と、気流案内方向が斜め方向D4となる組の各気流案内部20から吹出される気流についても、これらは同時に生じていることから、互いに影響を及ぼし合って一つにまとまり、開口部11の長手方向の他方への速度成分を残しつつ、その速度を低下させることで、天井に沿わない気流となる。 Moreover, the airflow blown out from each of the airflow guide portions 20 in the set whose airflow guide direction is the oblique direction D3 and the airflow blown out from each of the airflow guide portions 20 in the set whose airflow guide direction is the oblique direction D4 are also are occurring at the same time, they influence each other and combine into one, leaving the velocity component in the other longitudinal direction of the opening 11, while reducing its velocity, resulting in an airflow that does not follow the ceiling. .

これら二つにまとまった合成気流は、結果として、開口部11の長手方向の一方へ向かい、且つ、斜め下向きとなる第一の気流(図13中、気流E)と、開口部11の長手方向の他方へ向かい、且つ、斜め下向きとなる第二の気流(図13中、気流F)となって、それぞれ室内空間70を進行し、室内空間各部へ拡散していくこととなる(図13参照)。 As a result, these two combined combined airflows are the first airflow (airflow E in FIG. , and becomes a second airflow (airflow F in FIG. 13) that is directed obliquely downward, travels through the indoor space 70, and diffuses to various parts of the indoor space (see FIG. 13). ).

(本発明の第3の実施形態)
前記第1の実施形態に係る吹出口装置においては、各気流案内部20から吹出された気流の合成気流は所定の一方向に進むもののみとされる構成としているが、この他、第3の実施形態として、図14及び図15に示すように、各気流案内部20の気流案内方向の組合せを変えて、合成気流が三つの方向に進む三つの気流として得られる構成とすることもできる。
(Third embodiment of the present invention)
In the blower outlet device according to the first embodiment, the combined airflow of the airflows blown out from the respective airflow guide portions 20 is configured to proceed only in one predetermined direction. As an embodiment, as shown in FIGS. 14 and 15, by changing the combination of the airflow guiding directions of the respective airflow guide portions 20, it is also possible to obtain a configuration in which the combined airflow is obtained as three airflows traveling in three directions.

例えば、図14に示すように、吹出口11の中央における所定範囲の部位では、各気流案内部20を、その気流案内方向が吹出口11の長手方向の一方と短手方向の一方との間の斜め方向D1となる第一の組と、気流案内方向が吹出口11の長手方向の他方と短手方向の一方との間の斜め方向D3となる第二の組とに分ける。 For example, as shown in FIG. 14, at a predetermined range in the center of the blower outlet 11, each airflow guide portion 20 is arranged so that the airflow guide direction is between one of the longitudinal directions of the blower outlet 11 and one of the short side directions thereof. and a second group whose airflow guiding direction is an oblique direction D3 between the other longitudinal direction and one of the lateral directions of the outlet 11 .

また、吹出口11の前記所定範囲より一端部寄りの部位では、各気流案内部20を、その気流案内方向が吹出口11の長手方向の一方と短手方向の一方との間の斜め方向D1となる第三の組と、気流案内方向が吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となる第四の組とに分ける。さらに、吹出口11の前記所定範囲より他端部寄りの部位では、各気流案内部20を、その気流案内方向が吹出口11の長手方向の他方と短手方向の一方との間の斜め方向D3となる第五の組と、気流案内方向が吹出口11の長手方向の他方と短手方向の他方との間の斜め方向D4となる第六の組とに分ける。 In addition, at a portion closer to one end than the predetermined range of the blow-out port 11, each airflow guide portion 20 is arranged in an oblique direction D1 between one of the longitudinal directions of the blow-out port 11 and one of the short-side directions thereof. and a fourth group in which the airflow guiding direction is an oblique direction D2 between one of the longitudinal directions and the other of the lateral directions of the outlet 11 . Furthermore, at a portion closer to the other end than the predetermined range of the outlet 11, each airflow guide portion 20 is arranged so that the airflow guide direction is an oblique direction between the other longitudinal direction and one of the lateral directions of the outlet 11. They are divided into a fifth group D3 and a sixth group in which the airflow guide direction is an oblique direction D4 between the other longitudinal direction and the other lateral direction of the outlet 11 .

これら気流案内部の六つの組は、吹出口11の中央における所定範囲の部位で一列に並ぶ気流案内部20において、各気流案内部20の気流案内方向を斜め方向D1とする第一の組と、気流案内方向を斜め方向D3とする第二の組とが交互に入れ替わり、且つ、吹出口11の中央所定範囲より一端部寄りの部位で一列に並ぶ気流案内部20において、各気流案内部20の気流案内方向を斜め方向D1とする第三の組と、気流案内方向を斜め方向D2とする第四の組とが交互に入れ替わり、且つ、吹出口11の中央所定範囲より他端部寄りの部位で一列に並ぶ気流案内部20において、各気流案内部20の気流案内方向を斜め方向D3とする第五の組と、気流案内方向を斜め方向D4とする第六の組とが交互に入れ替わるように配設される。すなわち、隣り合う各気流案内部20同士で、気流案内方向が異なるように配設される。 These six sets of airflow guide portions are the first set in which the airflow guide direction of each airflow guide portion 20 is the diagonal direction D1 in the airflow guide portions 20 aligned in a predetermined range at the center of the outlet 11. , the airflow guide portions 20 alternately alternating with the second group having the airflow guide direction in the oblique direction D3 , and arranged in a row at a portion closer to one end than the central predetermined range of the blow-out port 11, each airflow guide portion 20 The third set in which the airflow guide direction is the oblique direction D1 and the fourth set in which the airflow guide direction is the oblique direction D2 are alternately replaced, and the air outlet 11 is located closer to the other end than the central predetermined range. In the airflow guide portions 20 arranged in a line at the site, the fifth set in which the airflow guide direction of each airflow guide portion 20 is the oblique direction D3 and the sixth set in which the airflow guide direction is the oblique direction D4 are alternately replaced. are arranged as follows. That is, adjacent airflow guide portions 20 are arranged so that the airflow guide directions are different.

この場合、各気流案内部20から吹出された気流の合成気流は、吹出口の長手方向の両方へ斜め下向きにそれぞれ進むと共に、吹出口中央から吹出口の短手方向の一方へ斜め下向きに進む状態となる。 In this case, the combined airflow of the airflows blown out from each airflow guide portion 20 advances obliquely downward in both longitudinal directions of the outlet, and also advances obliquely downward from the center of the outlet toward one of the widthwise directions of the outlet. state.

具体的には、各気流案内部20のうち、気流案内部20の第一の組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図14中で反時計回りに45°ずれた斜め方向D1へ、天井50に沿って水平に進もうとする(図14中、気流a)。 Specifically, in the first set of the airflow guide portions 20 among the airflow guide portions 20, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and the influence from the surroundings is temporarily reduced. In the case of a single blowout that does not receive, it tries to move horizontally along the ceiling 50 from one of the longitudinal directions of the blowout port 11 to an oblique direction D1 shifted counterclockwise by 45° in FIG. airflow a).

一方、気流案内部20の第二の組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の他方から、図14中で時計回りに45°ずれた斜め方向D3へ、天井50に沿って水平に進もうとする(図14中、気流c)。 On the other hand, in the second set of airflow guide portions 20, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and if it is a single blowout that is not affected by the surroundings, the airflow of the blowout port 11 is From the other longitudinal direction, it tries to advance horizontally along the ceiling 50 in an oblique direction D3 shifted clockwise by 45° in FIG. 14 (airflow c in FIG. 14).

また、気流案内部20の第三の組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図14中で反時計回りに45°ずれた斜め方向D1へ、天井50に沿って水平に進もうとする(図14中、気流a)。 In addition, in the third set of airflow guide portions 20, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and if it is a single blowout that is not affected by the surroundings, the airflow of the blowout port 11 is It tries to advance horizontally along the ceiling 50 in an oblique direction D1 shifted counterclockwise by 45° in FIG. 14 from one of the longitudinal directions (airflow a in FIG. 14).

そして、気流案内部20の第四の組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図14中で時計回りに45°ずれた斜め方向D2へ、天井50に沿って水平に進もうとする(図14中、気流b)。 In the fourth set of airflow guides 20, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and if it is a single blowout that is not affected by the surroundings, the airflow of the blowout port 11 is It tries to advance horizontally along the ceiling 50 in an oblique direction D2 shifted clockwise by 45° in FIG. 14 from one of the longitudinal directions (airflow b in FIG. 14).

さらに、気流案内部20の第五の組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の他方から、図14中で時計回りに45°ずれた斜め方向D3へ、天井50に沿って水平に進もうとする(図14中、気流c)。 Furthermore, in the fifth set of airflow guide portions 20, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and if it is a single blowout that is not affected by the surroundings, the airflow of the blowout port 11 is From the other longitudinal direction, it tries to advance horizontally along the ceiling 50 in an oblique direction D3 shifted clockwise by 45° in FIG. 14 (airflow c in FIG. 14).

この他、気流案内部20の第六の組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の他方から、図14中で反時計回りに45°ずれた斜め方向D4へ、天井50に沿って水平に進もうとする(図14中、気流d)。 In addition, in the sixth set of airflow guide portions 20, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and if it is a single blowout that is not affected by the surroundings, the blowout port 11 14 from the other longitudinal direction in FIG. 14 in an oblique direction D4 that is shifted counterclockwise by 45° and moves horizontally along the ceiling 50 (airflow d in FIG. 14).

実際には、気流案内方向が斜め方向D1となる第一の組の各気流案内部20から吹出される気流と、気流案内方向が斜め方向D3となる第二の組の各気流案内部20から吹出される気流は、同時に生じていることから、互いに影響を及ぼし合って一つにまとまり、開口部11の短手方向の一方への速度成分を残しつつ、その速度を低下させることで、天井に沿わない気流となる。 Actually, the airflow emitted from each of the first set of airflow guide portions 20 whose airflow guide direction is the oblique direction D1 and the airflow emitted from each of the second set of airflow guide portions 20 whose airflow guide direction is the oblique direction D3 Since the blown air currents are generated at the same time, they influence each other and unite into one. It becomes an air flow that does not follow the

また、気流案内方向が斜め方向D1となる第三の組の各気流案内部20から吹出される気流と、気流案内方向が斜め方向D2となる第四の組の各気流案内部20から吹出される気流も、同時に生じていることから、互いに影響を及ぼし合って一つにまとまり、開口部11の長手方向の一方への速度成分を残しつつ、その速度を低下させることで、天井に沿わない気流となる。 In addition, the airflow is blown from each of the third set of airflow guide portions 20 whose airflow guide direction is the oblique direction D1, and the airflow is blown from each of the fourth set of airflow guide portions 20 whose airflow guide direction is the oblique direction D2. Since the two airflows are also generated at the same time, they influence each other and merge into one. becomes an air current.

さらに、気流案内方向が斜め方向D3となる第五の組の各気流案内部20から吹出される気流と、気流案内方向が斜め方向D4となる第六の組の各気流案内部20から吹出される気流についても、これらは同時に生じていることから、互いに影響を及ぼし合って一つにまとまり、開口部11の長手方向の他方への速度成分を残しつつ、その速度を低下させることで、天井に沿わない気流となる。 Furthermore, the airflow blown from each of the fifth set of airflow guide portions 20 whose airflow guide direction is the oblique direction D3, and the airflow blown from each of the sixth set of airflow guide portions 20 whose airflow guide direction is the oblique direction D4. Since these airflows are also generated at the same time, they influence each other and merge into one. It becomes an air flow that does not follow the

このように、各気流案内部20から吹出される気流は、結果として、開口部11の中央から開口部11の短手方向の一方へ向かい、且つ、斜め下向きとなる第一の気流(図15中、気流G)と、開口部11の一端部寄りから開口部11の長手方向の一方へ向かい、且つ、斜め下向きとなる第二の気流(図15中、気流E)と、開口部11の他端部寄りから開口部11の長手方向の他方へ向かい、且つ、斜め下向きとなる第三の気流(図15中、気流F)との、三つの合成気流にまとめられて、それぞれ室内空間70を進行し、室内空間各部へ拡散していくこととなる(図15参照)。 In this way, the airflow blown out from each airflow guide portion 20 results in a first airflow (Fig. 15 middle, airflow G), a second airflow (airflow E in FIG. Together with the third airflow (airflow F in FIG. 15) directed from the other end toward the other in the longitudinal direction of the opening 11 and obliquely downward, the three combined airflows are combined into an indoor space 70. , and diffuses to various parts of the indoor space (see FIG. 15).

(本発明の第4の実施形態)
前記第1の実施形態に係る吹出口装置において、各気流案内部20から吹出された気流の合成気流は、開口部11の長手方向の一方へ向かい、且つ、斜め下向きの気流とされて室内空間を進む構成としているが、この他、第4の実施形態として、図16及び図17に示すように、各気流案内部20の気流案内方向の組合せを変えて、合成気流が主に垂直下向きの気流として得られる構成とすることもできる。
(Fourth embodiment of the present invention)
In the blower outlet device according to the first embodiment, the combined airflow of the airflows blown out from the respective airflow guide portions 20 is directed to one of the longitudinal directions of the opening 11 and is turned into an obliquely downward airflow, thereby forming an airflow in the indoor space. In addition, as a fourth embodiment, as shown in FIGS. 16 and 17, by changing the combination of the airflow guide directions of the respective airflow guide portions 20, the combined airflow is directed mainly vertically downward. It can also be configured to be obtained as an airflow.

例えば、図16に示すように、各気流案内部20を、その気流案内方向が吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となる組と、気流案内方向が吹出口11の長手方向の他方と短手方向の一方との間の斜め方向D3となる組とに分け、これら二つの組が、吹出口11の長手方向に一列に並ぶ気流案内部20で交互に入れ替わるように、すなわち、隣り合う各気流案内部20同士で、気流案内方向が正反対となるように配設する。 For example, as shown in FIG. 16, each airflow guide portion 20 is divided into a pair whose airflow guide direction is an oblique direction D2 between one of the longitudinal directions of the outlet 11 and the other of the widthwise directions thereof, and is divided into a group in the oblique direction D3 between the other longitudinal direction and one lateral direction of the outlet 11, and these two groups are arranged in a row in the longitudinal direction of the outlet 11 at the airflow guide part 20 Adjacent airflow guide portions 20 are arranged so that the airflow guide directions are opposite to each other.

この場合、各気流案内部20から吹出された気流の合成気流は、各気流案内部20の気流案内方向とは異なる、垂直下向きに進む状態となる。
具体的には、各気流案内部20のうち、気流案内部20での気流案内方向、すなわち、複数の案内羽根22の並ぶ向きが、吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図16中で時計回りに45°ずれた斜め方向D2へ、天井50に沿って水平に進もうとする(図16中、気流b)。
In this case, the combined airflow of the airflows blown out from the respective airflow guide portions 20 travels vertically downward, which is different from the direction of the airflow guidance of the respective airflow guide portions 20 .
Specifically, among the airflow guide portions 20, the airflow guide direction in the airflow guide portion 20, that is, the direction in which the plurality of guide blades 22 are arranged, is one of the longitudinal direction and the other of the width direction of the outlet 11. In the pair of diagonal direction D2 between, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and if it is a single blowout that is not affected by the surroundings, the longitudinal direction of the blowout port 11 16, it tries to advance horizontally along the ceiling 50 in an oblique direction D2 shifted clockwise by 45° in FIG. 16 (airflow b in FIG. 16).

一方、気流案内部20での気流案内方向が、吹出口11の長手方向の他方と短手方向の一方との間の斜め方向D3となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の他方から、図16中で時計回りに45°ずれた斜め方向D3へ、天井50に沿って水平に進もうとする(図16中、気流c)。 On the other hand, in a pair in which the airflow guiding direction in the airflow guide portion 20 is the oblique direction D3 between the other longitudinal direction and the one lateral direction of the outlet 11, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vane 22, and in the case of a single blowout that is not affected by the surroundings, the ceiling 50 (airflow c in FIG. 16).

実際には、気流案内方向が斜め方向D2となる組の各気流案内部20から吹出される気流と、気流案内方向が斜め方向D3となる組の各気流案内部20から吹出される気流は、同時に生じていることから、気流同士がぶつかり合って一つにまとまり、開口部11の長手方向への速度成分をわずかに残しつつ、気流同士がぶつかり合った分、大きく向きを変化させて天井から離れる気流となる。 Actually, the airflow blown out from each airflow guide portion 20 of the set whose airflow guide direction is the oblique direction D2 and the airflow blown from each airflow guide portion 20 of the set whose airflow guide direction is the oblique direction D3 are Since they are generated at the same time, the air currents collide with each other and unite into one. While leaving a slight velocity component in the longitudinal direction of the opening 11, the air currents collide with each other to greatly change the direction of the air currents from the ceiling. It becomes an air current that separates.

この一つにまとまった合成気流(図17中、気流H)は、結果として、各気流案内部20の気流案内方向とは異なった、垂直下向きの気流で、且つ開口部11の長手方向の両方へわずかに広がる気流となって室内空間70を進行し、室内空間各部へ拡散していくこととなる(図17参照)。 As a result, the combined airflow (airflow H in FIG. 17) is a vertically downward airflow different from the airflow guiding direction of each airflow guide portion 20, and both in the longitudinal direction of the opening 11. It becomes an air current that spreads slightly toward the inside, advances through the indoor space 70, and diffuses to various parts of the indoor space (see FIG. 17).

(本発明の第5の実施形態)
前記第4の実施形態に係る吹出口装置において、各気流案内部20から吹出された気流の合成気流は、垂直下向きの気流で、且つ、開口部11の長手方向の両方へわずかに広がる気流となって室内空間を進む構成としているが、この他、第5の実施形態として、図18及び図19に示すように、各気流案内部20の気流案内方向の組合せを変えて、合成気流が垂直下向きの気流で、且つ、開口部11の短手方向の両方へわずかに広がる気流として得られる構成とすることもできる。
(Fifth embodiment of the present invention)
In the blower outlet device according to the fourth embodiment, the combined airflow of the airflows blown out from the respective airflow guides 20 is a vertical downward airflow and an airflow that slightly spreads in both longitudinal directions of the opening 11. In addition, as a fifth embodiment, as shown in FIGS. 18 and 19, by changing the combination of the airflow guiding directions of the respective airflow guides 20, the combined airflow becomes vertical. It is also possible to obtain a downward airflow and an airflow that spreads slightly in both lateral directions of the opening 11 .

例えば、図18に示すように、各気流案内部20を、その気流案内方向が吹出口11の長手方向の一方と短手方向の一方との間の斜め方向D1となる組と、気流案内方向が吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となる組と、気流案内方向が吹出口11の長手方向の他方と短手方向の一方との間の斜め方向D3となる組と、気流案内方向が吹出口11の長手方向の他方と短手方向の他方との間の斜め方向D4となる組とに分ける。 For example, as shown in FIG. 18, each airflow guide portion 20 may be divided into a pair whose airflow guide direction is an oblique direction D1 between one of the longitudinal directions and one of the lateral directions of the outlet 11, and is an oblique direction D2 between one of the longitudinal directions and the other of the transverse directions of the outlet 11, and an oblique direction between the other of the longitudinal directions and one of the transverse directions of the outlet 11. They are divided into a group in the direction D3 and a group in which the airflow guide direction is an oblique direction D4 between the other longitudinal direction and the other lateral direction of the outlet 11 .

これら気流案内部の四つの組は、吹出口11の長手方向に一列に並ぶ気流案内部20において、各気流案内部20の気流案内方向を斜め方向D3とする組、気流案内方向を斜め方向D1とする組、気流案内方向を斜め方向D4とする組、気流案内方向を斜め方向D2とする組、の順で並べる配置状態を、吹出口11の長手方向一端部から他端部まで繰り返すように配設される。すなわち、隣り合う各気流案内部20同士で、気流案内方向が異なるように配設される。 These four sets of airflow guide portions are the set in which the airflow guide direction of each of the airflow guide portions 20 aligned in the longitudinal direction of the outlet 11 is the oblique direction D3, and the airflow guide direction of each of the airflow guide portions 20 is the oblique direction D1. , the group with the airflow guiding direction as the oblique direction D4, and the group with the airflow guiding direction as the oblique direction D2. are placed. That is, adjacent airflow guide portions 20 are arranged so that the airflow guide directions are different.

この場合、各気流案内部20から吹出された気流の合成気流は、各気流案内部20の気流案内方向とは異なる、垂直下向きに進む状態となる。
具体的には、各気流案内部20のうち、気流案内部20での気流案内方向が、吹出口11の長手方向の他方と短手方向の一方との間の斜め方向D3となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の他方から、図18中で時計回りに45°ずれた斜め方向D3へ、天井50に沿って水平に進もうとする(図18中、気流c)。
In this case, the combined airflow of the airflows blown out from the respective airflow guide portions 20 travels vertically downward, which is different from the direction of the airflow guidance of the respective airflow guide portions 20 .
Specifically, among the airflow guide portions 20, the airflow guide direction in the airflow guide portion 20 is the oblique direction D3 between the other longitudinal direction and the one lateral direction of the outlet 11. The airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and if it is a single blowout that is not affected by the surroundings, it flows clockwise from the other longitudinal direction of the blowout port 11 in FIG. It tries to advance horizontally along the ceiling 50 in an oblique direction D3 shifted by 45° (airflow c in FIG. 18).

一方、気流案内部20での気流案内方向、すなわち、複数の案内羽根22の並ぶ向きが、吹出口11の長手方向の一方と短手方向の一方との間の斜め方向D1となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図18中で反時計回りに45°ずれた斜め方向D1へ、天井50に沿って水平に進もうとする(図18中、気流a)。 On the other hand, in a set in which the airflow guiding direction in the airflow guide portion 20, that is, the direction in which the plurality of guide vanes 22 are arranged, is the oblique direction D1 between one of the longitudinal directions and one of the lateral directions of the outlet 11, The airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22. In the case of a single blowout that is not affected by the surroundings, the airflow flows counterclockwise in FIG. It tries to move horizontally along the ceiling 50 in an oblique direction D1 shifted by 45° (airflow a in FIG. 18).

また、気流案内部20での気流案内方向が、吹出口11の長手方向の他方と短手方向の他方との間の斜め方向D4となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の他方から、図18中で反時計回りに45°ずれた斜め方向D4へ、天井50に沿って水平に進もうとする(図18中、気流d)。 In addition, in a set in which the airflow guiding direction of the airflow guide portion 20 is the oblique direction D4 between the other longitudinal direction and the other lateral direction of the outlet 11, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vane 22, and in the case of a single blowout that is not affected by the surroundings, the ceiling It tries to move horizontally along 50 (airflow d in FIG. 18).

さらに、気流案内部20での気流案内方向が、吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図18中で時計回りに45°ずれた斜め方向D2へ、天井50に沿って水平に進もうとする(図18中、気流b)。 Furthermore, in a pair in which the airflow guiding direction in the airflow guide portion 20 is the oblique direction D2 between one of the longitudinal directions and the other of the lateral directions of the outlet 11, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22. In the case of a single blowout that is not affected by the surroundings, from one of the longitudinal directions of the blowout port 11, in FIG. (airflow b in FIG. 18).

実際には、各気流案内部20から吹出される気流は同時に生じていることから、気流案内方向が斜め方向D3となる組の各気流案内部20から吹出される気流と、気流案内方向が斜め方向D1となる組の各気流案内部20から吹出される気流とがぶつかり合ってまとまり、開口部11の短手方向の一方への速度成分を残しつつ、気流同士がぶつかり合った分、大きく向きを変化させて天井から離れる気流となる。また、気流案内方向が斜め方向D4となる組の各気流案内部20から吹出される気流と、気流案内方向が斜め方向D2となる組の各気流案内部20から吹出される気流とがぶつかりあってまとまり、開口部11の短手方向の一方への速度成分を残しつつ、気流同士がぶつかり合った分、大きく向きを変化させて天井から離れる気流となる。 Actually, the airflows blown out from the respective airflow guide portions 20 are generated at the same time. The airflows blown out from each of the airflow guide portions 20 of the set in the direction D1 collide and converge, leaving a velocity component in one of the lateral directions of the opening 11, while the airflows collide with each other to increase the direction. changes and becomes an air current that moves away from the ceiling. Also, the air currents blown out from the air current guide portions 20 of the group whose air current guide direction is the oblique direction D4 collide with the air currents blown from the air current guide portions 20 of the group whose air current guide direction is the oblique direction D2. The air currents collide with each other while leaving a velocity component in one of the width directions of the opening 11, and the direction of the air currents is greatly changed to move away from the ceiling.

こうした中、隣り合う気流案内部のうち、吹出される気流の向きが正反対となっている一の箇所で、気流案内方向が斜め方向D1となる組の各気流案内部20から吹出される気流の成分と、気流案内方向が斜め方向D4となる組の各気流案内部20から吹出される気流の成分とが、互いに引き寄せ合って開口部11の短手方向の速度成分を小さくし、まとまった気流の他の方向への速度成分を相対的に強める。また同様に、隣り合う気流案内部のうち、吹出される気流の向きが正反対となっている他の箇所で、気流案内方向が斜め方向D2となる組の各気流案内部20から吹出される気流の成分と、気流案内方向が斜め方向D3となる組の各気流案内部20から吹出される気流の成分とが、互いに引き寄せ合って開口部11の短手方向の速度成分を小さくし、まとまった気流の他の方向への速度成分を相対的に強める。 Under these circumstances, among the adjacent airflow guide portions, at one point where the direction of the blown airflow is opposite, the airflow blown from each of the airflow guide portions 20 of the set whose airflow guide direction is the oblique direction D1. component and the component of the airflow blown out from each of the airflow guide portions 20 of the set whose airflow guide direction is the oblique direction D4 attract each other to reduce the velocity component in the widthwise direction of the opening 11, resulting in a unified airflow. relatively strengthens the velocity component in the other direction. Similarly, among the adjacent airflow guide portions, the airflow is blown out from each of the airflow guide portions 20 of the set whose airflow guide direction is the oblique direction D2 at other locations where the direction of the blown airflow is opposite. component and the component of the airflow blown out from each of the airflow guide portions 20 of the group whose airflow guide direction is the oblique direction D3 attract each other to reduce the speed component in the lateral direction of the opening 11, and are gathered together. Relatively strengthen the velocity components in other directions of the airflow.

これにより、吹出された気流同士がぶつかり合って天井から離れる気流としてまとまった各気流が、それぞれ開口部11の短手方向への速度成分を小さくされる分、互いに影響を及ぼし合う度合いを大きくして最終的に一つにまとまり、開口部11の短手方向への速度成分をわずかに残しつつ、天井から離れる下向きの気流となる。 As a result, the blown air currents colliding with each other and collected as air currents moving away from the ceiling increase the degree of influence on each other by the amount that the velocity components in the lateral direction of the opening 11 are reduced. Finally, they come together to form a downward airflow away from the ceiling while leaving a slight velocity component in the lateral direction of the opening 11 .

この一つにまとまった合成気流(図19中、気流I)は、結果として、各気流案内部20の気流案内方向とは異なった、垂直下向きの気流で、且つ開口部11の短手方向の両方へわずかに広がる気流となって室内空間70を進行し、室内空間各部へ拡散していくこととなる(図19参照)。 As a result, the combined airflow (airflow I in FIG. 19) is a vertically downward airflow different from the airflow guiding direction of each airflow guide portion 20, and also in the width direction of the opening 11. As an air current that spreads slightly in both directions, it travels through the indoor space 70 and spreads to various parts of the indoor space (see FIG. 19).

(本発明の第6の実施形態)
前記第1の実施形態に係る吹出口装置において、各気流案内部20は、隣り合う各気流案内部同士で、案内羽根22の並ぶ向き、すなわち、気流案内方向を互いに異ならせるように開口部11にそれぞれ配設されて、気流案内部20から吹出された気流の合成気流の進行方向を、気流案内部20ごとの吹出方向とは異なる向きとされる構成としているが、これに限らず、第6の実施形態として、図20に示すように、気流案内部20を複数の組に分ける際に、同じ組の気流案内部がまとまるように配置して、隣り合う各気流案内部同士で、気流案内方向が同じ向きとなる箇所を生じさせ、合成気流の向きを一部の気流案内部20の気流案内方向と一致させる構成とすることもできる。
(Sixth embodiment of the present invention)
In the blower outlet device according to the first embodiment, each airflow guide portion 20 has an opening portion 11 such that the direction in which the guide blades 22 line up, i.e., the airflow guide direction, is different between adjacent airflow guide portions. , and the traveling direction of the composite airflow of the airflows blown out from the airflow guide portions 20 is different from the blowing direction of each airflow guide portion 20, but not limited to this, the second 6, when the airflow guide portions 20 are divided into a plurality of groups, as shown in FIG. It is also possible to create a portion where the guiding directions are the same, and make the direction of the combined airflow coincide with the airflow guiding direction of some of the airflow guiding portions 20 .

例えば、図20に示すように、吹出口11の中央から一端部寄りの部位で、各気流案内部20を、その気流案内方向が吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となる組とし、吹出口11の中央から他端部寄りの部位で、各気流案内部20を、その気流案内方向が吹出口11の長手方向の他方と短手方向の他方との間の斜め方向D4となる組とする。 For example, as shown in FIG. 20, each airflow guide portion 20 is arranged at a portion closer to one end from the center of the blowout port 11 so that the airflow guide direction is one of the longitudinal directions of the blowout port 11 and the other of the widthwise directions. At a portion closer to the other end from the center of the blowout port 11, each airflow guide portion 20 is set so that its airflow guide direction is the other in the longitudinal direction and the other in the short direction of the blowout port 11. and the diagonal direction D4 between .

これら気流案内部の二つの組は、吹出口11の中央から一端部寄りの部位で一列に並ぶ気流案内部20において、各気流案内部20の気流案内方向を斜め方向D2とする組のみとなり、且つ、吹出口11の中央から他端部寄りの部位で一列に並ぶ気流案内部20において、各気流案内部20の気流案内方向を斜め方向D4とする組のみとなるように配設される。すなわち、複数の組に分けられた気流案内部20が、各組ごとに調和空気を案内して吹出す向きを異ならせるようにされる一方、吹出口11の中央を除いて、隣り合う各気流案内部20同士で、気流案内方向は異なることなく一致する。 These two sets of airflow guide portions are only the set in which the airflow guide direction of each airflow guide portion 20 is the oblique direction D2 in the airflow guide portions 20 aligned in a row near one end portion from the center of the blowout port 11, In addition, in the airflow guide portions 20 aligned in a row near the other end portion from the center of the outlet 11, the airflow guide direction of each airflow guide portion 20 is arranged so as to form only a set in which the airflow guide direction is the oblique direction D4. That is, the airflow guide portions 20 divided into a plurality of groups guide the conditioned air in different directions for each group. The guide portions 20 have the same airflow guide direction without being different.

この場合、各気流案内部20から吹出された気流の合成気流は、前記斜め方向D2、D4の二方向へほぼ水平に進む状態となる。
具体的には、各気流案内部20のうち、吹出口11の中央から一端部寄りの部位に配設され、気流案内部20での気流案内方向、すなわち、複数の案内羽根22の並ぶ向きが、吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図20中で時計回りに45°ずれた斜め方向D2へ、天井50に沿って水平に進もうとする(図20中、気流b)。
In this case, the combined airflow of the airflows blown out from the respective airflow guide portions 20 is in a state of traveling substantially horizontally in the two diagonal directions D2 and D4.
Specifically, among the airflow guide portions 20, the airflow guide direction of the airflow guide portion 20, that is, the direction in which the plurality of guide vanes 22 are arranged, is arranged at a portion closer to one end portion from the center of the blowout port 11. , in a pair of oblique directions D2 between one longitudinal direction and the other lateral direction of the outlet 11, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, 20 from one of the longitudinal directions of the outlet 11 to the oblique direction D2 shifted clockwise by 45° in FIG. middle, airflow b).

一方、各気流案内部20のうち、吹出口11の中央から他端部寄りの部位に配設され、気流案内部20での気流案内方向が、吹出口11の長手方向の他方と短手方向の他方との間の斜め方向D4となる組では、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の他方から、図20中で反時計回りに45°ずれた斜め方向D4へ、天井50に沿って水平に進もうとする(図20中、気流d)。 On the other hand, among the airflow guide portions 20, the airflow guide portions 20 are arranged in a portion closer to the other end portion than the center of the blowout port 11, and the airflow guide directions of the airflow guide portions 20 are the other of the longitudinal directions of the blowout port 11 and the short side direction. In the pair in the oblique direction D4 between the other and the other, the airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and if it is a single blowout that is not affected by the surroundings, the blowout port 11 20 from the other longitudinal direction in FIG. 20 in an oblique direction D4 shifted counterclockwise by 45° and horizontally along the ceiling 50 (airflow d in FIG. 20).

実際には、気流案内方向が斜め方向D2となる組の各気流案内部20から吹出される気流と、気流案内方向が斜め方向D4となる組の各気流案内部20から吹出される気流は、同時に生じていることから、互いに影響を及ぼし合うが、その影響は、隣り合う気流案内部同士で気流案内方向が互いに異なる開口部11の中央のみに留まることとなり、気流案内方向が同じとなっている複数の気流案内部から吹出される気流が単純にまとまる状態となり、前記各斜め方向への進行速度をほぼ維持して、天井に沿って水平に進む気流となる。 Actually, the airflow blown out from each airflow guide portion 20 of the set whose airflow guide direction is the oblique direction D2 and the airflow blown from each airflow guide portion 20 of the set whose airflow guide direction is the oblique direction D4 are Since they occur at the same time, they influence each other, but the influence is limited only to the center of the opening 11 in which the airflow guiding directions of the adjacent airflow guiding portions are different from each other, and the airflow guiding directions are the same. The airflows blown out from the plurality of airflow guide portions are simply converged, and the airflows advance horizontally along the ceiling while substantially maintaining the advancing speed in each of the oblique directions.

こうして二つにまとまった合成気流は、結果として、斜め方向D2へ向かい、且つ、水平向きとなる第一の気流(図20中、気流J)と、斜め方向D4へ向かい、且つ、水平向きとなる第二の気流(図20中、気流K)となって、それぞれ室内空間70を進行し、室内空間各部へ拡散していくこととなる(図20参照)。 As a result, the two combined airflows are divided into a first airflow (airflow J in FIG. 20) that goes in the diagonal direction D2 and is horizontal, and a first airflow (airflow J in FIG. 20) that goes in the diagonal direction D4 and is horizontal. The second airflow (airflow K in FIG. 20) travels through the indoor space 70 and diffuses to various parts of the indoor space (see FIG. 20).

(本発明の第7の実施形態)
前記第1の実施形態に係る吹出口装置において、各気流案内部20は、開口部11に配設される状態で、複数の組に分けられ、その各組ごとに調和空気を案内して吹出す向きを異ならせるようにされる構成としているが、これに限らず、第7の実施形態として、図21に示すように、気流案内部20を複数の組に分けず、開口部に配設される全ての気流案内部20が、その気流案内方向を同じ一つの向きとされ、合成気流の向きを気流案内部20の気流案内方向と一致させる構成とすることもできる。
例えば、図21に示すように、吹出口11の各気流案内部20を、その気流案内方向が吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2となるようにする。
(Seventh embodiment of the present invention)
In the air outlet device according to the first embodiment, each air flow guide part 20 is arranged in the opening part 11 and is divided into a plurality of groups. Although the configuration is such that the direction of discharge is made different, as a seventh embodiment, as shown in FIG. All of the airflow guides 20 may have the same airflow guide direction, and the direction of the combined airflow may be the same as the airflow guide direction of the airflow guides 20 .
For example, as shown in FIG. 21, each airflow guide portion 20 of the outlet 11 is arranged so that the airflow guide direction is an oblique direction D2 between one of the longitudinal directions and the other of the lateral directions of the outlet 11. do.

この場合、各気流案内部20から吹出された気流の合成気流は、前記斜め方向D2へほぼ水平に進む状態となる。
具体的には、各気流案内部20は、気流案内部20での気流案内方向、すなわち、複数の案内羽根22の並ぶ向きが、吹出口11の長手方向の一方と短手方向の他方との間の斜め方向D2とされており、案内羽根22間を通った調和空気の気流は、案内羽根22による案内で、仮に周囲からの影響を受けない単独吹出の場合、吹出口11の長手方向の一方から、図21中で時計回りに45°ずれた斜め方向D2へ、天井50に沿って水平に進もうとする(図21中、気流b)。
In this case, the combined airflow of the airflows blown out from the respective airflow guide portions 20 is in a state of traveling substantially horizontally in the oblique direction D2.
Specifically, in each airflow guide portion 20, the airflow guide direction in the airflow guide portion 20, that is, the direction in which the plurality of guide vanes 22 are arranged is the same as the one in the longitudinal direction of the outlet 11 and the other in the lateral direction. The airflow of the conditioned air passing between the guide vanes 22 is guided by the guide vanes 22, and if it is a single blowout that is not affected by the surroundings, it is in the longitudinal direction of the blowout port 11. From one side, it tries to advance horizontally along the ceiling 50 in an oblique direction D2 shifted clockwise by 45° in FIG. 21 (airflow b in FIG. 21).

実際には、各気流案内部20から吹出される気流は、同時に生じていることから、互いに影響を及ぼし合うが、その影響は、気流案内方向が同じとなっている複数の気流案内部から吹出される気流を一つにまとめる程度のものとなり、前記斜め方向D2への進行速度をほぼ維持して、天井に沿って水平に進む気流となる。 In reality, the airflows blown out from the respective airflow guides 20 are generated at the same time, and thus affect each other. The air currents are collected into one, and the air current advances horizontally along the ceiling while substantially maintaining the traveling speed in the oblique direction D2.

こうして一つにまとまった合成気流は、結果として、そのまま斜め方向D2へ向かい、且つ、水平向きとなる気流(図21中、気流J)となって、室内空間70を進行し、室内空間各部へ拡散していくこととなる(図21参照)。 As a result, the combined airflow is directed in the diagonal direction D2 as it is and becomes a horizontal airflow (airflow J in FIG. 21), advances in the indoor space 70, and travels to various parts of the indoor space. It will spread (see FIG. 21).
