Description

本発明は、空気調和対象空間に調和空気を吹出して空気調和を行う吹出口装置に関し、特に、グリッド式システム天井用の吹出口装置に関する。   The present invention relates to an air outlet device that blows conditioned air into an air conditioning target space to perform air conditioning, and more particularly, to an air outlet device for a grid system ceiling.

空気調和設備において、ダクトを通じて送られる調和空気を空気調和対象の室内空間に吹出す吹出口装置は、室内空間への調和空気の到達しやすさ等を考慮して天井に配設されることが多い。こうした吹出口装置を配設される天井が、ビル内のオフィス空間等のように、天井パネルや照明器具等を一つのシステムとして、共通の線状に連続する支持枠で支持して構成される、いわゆるシステム天井である場合には、吹出口装置も、支持枠に取付けられてシステム天井の一部をなす構造のものが採用される。   In an air conditioning facility, an air outlet device that blows out conditioned air sent through a duct to an indoor space subject to air conditioning may be disposed on the ceiling in consideration of the ease of conditioned air reaching the indoor space. Many. The ceiling on which such an air outlet device is arranged is configured by supporting a ceiling panel, a lighting fixture, etc. as a single system, such as an office space in a building, with a common linear continuous support frame. In the case of a so-called system ceiling, a blower outlet device that is attached to the support frame and forms a part of the system ceiling is employed.

システム天井では、線状に配置された支持枠に沿って天井材や吹出口を配設する関係上、吹出口その他の取付け、取外しは支持枠に沿った一列分で取扱う必要があり、対象物である吹出口のみ取扱って着脱等行うような簡略な対応で済ませることができないという問題があった。このため、近年では、天井における吹出口を含む各種天井ユニットをより細かい単位でレイアウト可能にする、グリッド式のシステム天井の使用頻度が増大している。   In the system ceiling, because the ceiling material and air outlets are arranged along the support frame arranged in a line, it is necessary to handle the air outlets and other attachments and removals in one row along the support frame. However, there is a problem that it is not possible to deal with a simple response such as handling only the air outlet and attaching / detaching. For this reason, in recent years, the frequency of use of grid type system ceilings that enables various ceiling units including the air outlets in the ceiling to be laid out in finer units has increased.

従来のグリッド式のシステム天井（以降、グリッド天井と呼称）では、天井パネルや照明器具等を一つのシステムとして共通の格子（グリッド）状に組合わされた支持枠で支持しており、吹出口装置は、照明器具等他の機器と合わせて、一つのグリッドに収められる形で支持枠に取付けられ、天井の一部をなしている。そして、吹出口装置は、照明器具等他の天井配設機器との組合わせの関係で、室内空間に面するその開口部分は、一般に矩形（長方形）となっている。このような従来のグリッド天井用の吹出口装置の例として、特開２００２−３１０４９３号公報に開示されるものがある。   In conventional grid-type system ceilings (hereinafter referred to as grid ceilings), ceiling panels and lighting fixtures are supported as a single system by a support frame combined in a common grid (grid) shape. Is attached to the support frame so as to be housed in one grid together with other equipment such as lighting equipment, and forms a part of the ceiling. And the blower outlet device is generally rectangular (rectangular) in its opening portion facing the indoor space because of a combination with other ceiling-arranged devices such as lighting fixtures. As an example of such a conventional air outlet device for a grid ceiling, there is one disclosed in Japanese Patent Application Laid-Open No. 2002-310493.

特開２００２−３１０４９３号公報JP 2002-310493 A

従来のグリッド天井は、複数のグリッドからなる正方形の基本モジュールを部屋の広さに応じて複数並べて組合わされて、一部屋の天井として形成されている。また、室内空間では、グリッド天井の一又は複数のモジュールを一区画として間仕切りが設けられる場合もあり、照明器具等他の天井配設機器との組合わせで用いられるグリッド天井用の吹出口装置は、グリッド天井のモジュールごとに配設されるのが一般的である。   A conventional grid ceiling is formed as a ceiling of a single room by combining a plurality of square basic modules composed of a plurality of grids according to the size of the room. Moreover, in an indoor space, a partition may be provided with one or a plurality of modules of the grid ceiling as one section, and the outlet device for the grid ceiling used in combination with other ceiling-arranged devices such as lighting fixtures is provided. Generally, it is arranged for each module of the grid ceiling.

このため、グリッド天井の場合、一モジュール単位で吹出口から居住域各部へ吹出気流が均等に到達することが望まれている。しかし、グリッド天井の場合、モジュールにおいて均等に分散配置される複数の照明器具のいずれかとの組合せで吹出口装置が配置される関係上、吹出口装置がモジュールの中央、すなわち、室内空間や間仕切りで仕切られた区画の中央に位置することは少なく、天井に吹出口が偏在した状態とならざるを得ない。   For this reason, in the case of a grid ceiling, it is desired that the blown airflow reaches the living area uniformly from the blowout port in units of one module. However, in the case of a grid ceiling, the air outlet device is arranged at the center of the module, i.e., in the interior space or partition, because the air outlet device is arranged in combination with any of a plurality of lighting fixtures that are uniformly distributed in the module. It is rare to be located in the center of the partitioned compartment, and the air outlets are unevenly distributed on the ceiling.

こうした偏った配置となる吹出口として、従来から天井で一般的に用いられる、四方向吹出しの角型吹出口装置を採用した場合、一モジュールの範囲で吹出口からの気流が到達しない領域が生じ、また、壁や間仕切りに近い側の吹出しにおいては、居住域でのドラフトを招くなど、気流の拡散性能に難があり、モジュール全体に均等に気流を到達させるには少なくとも二つの吹出口が必要となり、高コストとなってしまうという課題を有していた。   As a blower outlet with such a biased arrangement, when a square blower device with a four-way blower, which has been conventionally used on the ceiling, is used, there is an area where the airflow from the blower outlet does not reach within the range of one module. In addition, the blowout on the side close to the wall or partition has a difficulty in airflow diffusion performance, such as inviting a draft in the living area, and at least two outlets are required to reach the airflow uniformly throughout the module. Therefore, it has a problem of high cost.

また、仮に、吹出気流が偏在しないようにガイドベーン（案内羽根）を適切に配置した構造を採用し、グリッド天井での偏った配置に対応できる吹出口を構成できたとしても、冷房効率向上のために一般的な冷房用空気より低温の調和空気を吹出して空気調和を行おうとする場合、室内空気との温度差で低温の調和空気がより下降しやすく、天井に沿って水平に進む力が弱くなるため、気流を水平向きとして周囲各方向に進行させることは難しく、気流の到達範囲を確保して十分な空気調和効果を得るのが困難になるという課題を有していた。   In addition, even if a structure in which guide vanes (guide vanes) are appropriately arranged so that the blown airflow is not unevenly distributed and an air outlet that can cope with the uneven arrangement on the grid ceiling can be configured, the cooling efficiency can be improved. Therefore, when trying to perform air conditioning by blowing cool air at a lower temperature than general cooling air, the cold air tends to descend more easily due to the temperature difference from the room air, and the force to move horizontally along the ceiling Since it becomes weak, it is difficult to make the air flow horizontal and advance in the surrounding directions, and there is a problem that it is difficult to secure a range of the air flow and obtain a sufficient air conditioning effect.

この他、グリッド天井で吹出口が偏った配置となる場合、吹出口に近い壁等の影響による、吹出気流の居住域への到達度合いの偏りを防ぐため、吹出口の壁に近い側には調和空気を吹出さないようにすることが考えられるが、単純に吹出し方向を限定すると、冷房の場合、調和空気が吹出されない部位の吹出口外縁部等の表面に、誘引された室内の温かい二次空気が接触することとなる。この吹出口外縁部は、調和空気と接触する他部分との熱伝導に伴い冷却されていることから、温かい二次空気の接触により結露の生じるおそれがあるという課題を有していた。   In addition to this, when the outlet is biased on the grid ceiling, in order to prevent the deviation of the degree of arrival of the blowing airflow to the living area due to the influence of the wall near the outlet, Although it is conceivable not to blow out the conditioned air, simply limiting the blowing direction, in the case of cooling, in the case of cooling, on the surface such as the outer edge of the outlet of the part where the conditioned air is not blown, The next air will come into contact. Since this blower outlet outer edge part is cooled with heat conduction with other parts that come into contact with conditioned air, there is a problem that condensation may occur due to contact with warm secondary air.

本発明は前記課題を解消するためになされたもので、グリッド式システム天井の各モジュールにおいて、一つでモジュール全体に気流を均等に到達させられると共に、低温の調和空気を吹出す場合でも十分な到達範囲を確保でき、低コストで効率よく空気調和を行える低温吹出口装置を提供することを目的とする。   The present invention has been made to solve the above problems, and in each module of the grid system ceiling, it is possible to evenly reach the entire module with air current and to blow out low-temperature conditioned air. An object of the present invention is to provide a low-temperature air outlet device that can secure a reachable range and can perform air conditioning efficiently at low cost.

本発明に係る低温吹出口装置は、複数のグリッドを有する基本のモジュールを一又は複数組合わせてなるグリッド式のシステム天井に配設され、空気調和対象となる空間にダクトから供給された調和空気を天井に沿って略水平に吹出す、グリッド式のシステム天井用吹出口装置において、前記調和空気が通過する矩形開口断面の開口部を取囲んだ略箱状体として形成され、天井をなす前記モジュールの所定位置に配設され、前記ダクトと接続されて調和空気を供給され、調和空気を空気調和対象空間へ吹出す吹出口本体と、横方向に所定間隔を空けて並べられた複数の略板状の案内羽根を有して、前記吹出口本体内側の前記開口部に配設され、案内羽根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の並んだ向きに案内する一又は複数の気流案内体と、調和空気の通過可能な開口孔を複数穿設される略板状体で形成され、前記気流案内体の上側に重ねて配設され、気流案内体における案内羽根間の空気通路部分への調和空気の進入を一部制限する制御板とを備え、前記気流案内体が、略平行に並んだ複数の案内羽根の組からなる単位案内部を互いに向きを異ならせて複数組有し、又は、複数の気流案内体ごとに案内羽根の並ぶ向きを個別に設定され、且つ、前記複数組の単位案内部、又は、複数の気流案内体が、前記吹出口本体の開口部全体にわたって隙間無く並べて配置され、前記制御板が、気流案内体における案内羽根間の空気通路部分のうち、各案内羽根の上端から気流案内方向の前側所定範囲に前記開口孔を位置させる一方、各案内羽根の上端から気流案内方向の後側所定範囲を塞ぐ形状とされ、前記気流案内体の各単位案内部又は各気流案内体でそれぞれ案内された横向きの調和空気の気流が、吹出口装置を中心として放射状に進行しつつ、合成気流となって拡散するものである。   The low-temperature air outlet apparatus according to the present invention is arranged on a grid-type system ceiling formed by combining one or a plurality of basic modules having a plurality of grids, and is conditioned air supplied from a duct to a space to be air-conditioned. In the grid-type system ceiling air outlet device, which is blown out substantially horizontally along the ceiling, the air-conditioning device is formed as a substantially box-like body surrounding the opening of the rectangular opening cross section through which the conditioned air passes, and forms the ceiling. A plurality of abbreviations arranged at predetermined intervals in the lateral direction, and arranged at predetermined positions in the module, connected to the duct and supplied with conditioned air and blowing the conditioned air to the air-conditioning target space; It has a plate-shaped guide vane and is arranged in the opening inside the air outlet body, and guides the conditioned air in the direction in which the guide vanes are aligned while allowing the conditioned air to pass through the air passage portion between the guide vanes. You One or a plurality of airflow guide bodies and a substantially plate-like body in which a plurality of opening holes through which conditioned air can pass are formed, and are arranged on the upper side of the airflow guide body. A control plate that partially restricts the inflow of conditioned air into the air passage portion between, and the airflow guide body makes unit guide portions composed of a plurality of guide blades arranged substantially parallel to each other in different directions. A plurality of airflow guides, and the direction in which the guide blades are arranged for each of the plurality of airflow guide bodies is set individually, and the plurality of unit guide portions or the plurality of airflow guide bodies are provided on the outlet body. The control plate is arranged side by side with no gap over the entire opening, and the control plate positions the opening hole in a predetermined range on the front side in the airflow guide direction from the upper end of each guide blade among the air passage portions between the guide blades in the airflow guide body. Airflow from the top of each guide vane The air flow of laterally conditioned air guided by each unit guide portion or each air flow guide body of the air flow guide body advances radially around the air outlet device. However, it diffuses as a synthetic airflow.

このように本発明によれば、吹出口本体における矩形開口断面の開口部に、調和空気の気流を複数の方向にそれぞれ案内する気流案内体を配設すると共に、気流案内体に重ねて制御板を配設し、気流案内体への調和空気の流入を制御板で調整した上で、気流案内体で調和空気の気流を案内して、モジュールの吹出口位置から放射状に気流を進ませることにより、制御板が調和空気を適切に案内羽根の上面に導いてこれに沿わせ、案内羽根の横方向案内性能を十分に発揮させることができ、調和空気の気流を開口部から確実に横向きに吹き出して、モジュールにおける広範囲の領域に、開口部からの吹出気流を拡散させる状態を得られることとなり、低温の調和空気の場合でも横方向の到達距離を十分に確保でき、モジュールにおいて吹出口からの気流の到達しない部位が生じにくく、一つの吹出口からモジュールのほぼ全域に気流を均等に拡散させて空気調和を実現でき、一モジュールに一つの吹出口を配置すれば足りることとなり、空気調和のコストを抑えられる。また、吹出口を照明器具等の天井配設機器との組合わせで、モジュールの中央でない箇所に配設される状態としても空気調和上の問題を生じることはなく、吹出口も含む全体で調和のとれた天井デザインと空気調和性能との両立が図れる。   As described above, according to the present invention, the air flow guide body that guides the air flow of the conditioned air in each of the plurality of directions is disposed in the opening portion of the rectangular opening cross section of the outlet body, and the control plate is superimposed on the air flow guide body. After adjusting the inflow of conditioned air to the airflow guide body with the control board, guide the airflow of conditioned air with the airflow guide body and advance the airflow radially from the outlet position of the module The control plate can guide the conditioned air appropriately to the upper surface of the guide vane and follow it, so that the lateral guidance performance of the guide vane can be sufficiently exerted, and the air flow of the conditioned air is surely blown out sideways from the opening. As a result, it is possible to obtain a state in which the blown airflow from the opening is diffused in a wide area in the module, and even in the case of low-temperature conditioned air, a sufficient lateral distance can be secured. It is difficult to generate a part where the airflow does not reach, and air conditioning can be realized by evenly diffusing the airflow from one air outlet to almost the entire area of the module, and it is sufficient to arrange one air outlet in one module. Can reduce costs. Moreover, even if the air outlet is combined with a ceiling-arranged device such as a lighting fixture, the air conditioning problem does not occur even if the air outlet is disposed at a location other than the center of the module. A balance between a well-designed ceiling design and air-conditioning performance can be achieved.

この吹出口装置１は、詳細には、矩形開口断面の開口部１１を取囲んだ略箱状体として形成され、天井５０内でダクト５１と接続されて空気調和対象の室内空間における天井５０に配設される吹出口本体１０と、この吹出口本体１０内側の開口部１１に配設されて調和空気の吹出す方向を複数の向きに案内する気流案内体３０と、気流案内体３０の上側に重ねて配設される略板状の制御板２０と、吹出口本体１０の開口部１１及び各気流案内体３０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孔４１を多数穿設されて吹出口本体１０の室内側端部に配設される化粧グリル４０とを備える構成である。   More specifically, the air outlet device 1 is formed as a substantially box-like body surrounding the opening 11 having a rectangular opening cross section, and is connected to the duct 51 in the ceiling 50 to be attached to the ceiling 50 in the indoor space subject to air conditioning. An air outlet guide body 10, an airflow guide body 30 that is provided in the opening 11 inside the air outlet body 10 and guides the direction in which conditioned air is blown out in a plurality of directions, and an upper side of the airflow guide body 30 A substantially plate-shaped control plate 20 that is disposed on top of each other, and a substantially plate-shaped body that is large enough to cover the opening 11 of the outlet body 10 and each airflow guide body 30, and through which the conditioned air passes. And a decorative grill 40 disposed at the indoor side end of the outlet body 10.

この吹出口装置１を隅部８５に一つ取付けられ、天井５０をなすモジュール８０は、６×６＝３６のグリッドを組合わされてなる正方形となっており、このモジュール８０の等長の四つの外辺部は、前記所定の隅部８５を挟む第一の辺８１及び第二の辺８２と、前記吹出口本体１０の開口部１１長辺方向と平行な第一の辺８１に対し平行となる第三の辺８３と、前記吹出口本体１０の開口部１１長辺方向と直交する第二の辺８２に対し平行となる第四の辺８４とからなる。   One of the outlets 1 is attached to the corner 85, and the module 80 forming the ceiling 50 is a square formed by combining 6 × 6 = 36 grids. The outer side is parallel to the first side 81 and the second side 82 sandwiching the predetermined corner 85 and the first side 81 parallel to the long side direction of the opening 11 of the outlet body 10. And a fourth side 84 that is parallel to the second side 82 orthogonal to the long side direction of the opening 11 of the outlet body 10.

前記吹出口本体１０は、調和空気の通過する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箱状体として形成され、天井５０に格子状に組立配設されたグリッド式システム天井用の公知の支持枠５２に照明器具５３など他の天井配設機器と共に支持される構成である（図１参照）。   The air outlet body 10 is formed as a substantially box-like body made of a high-strength material such as metal and surrounds the opening 11 having a rectangular opening cross section through which conditioned air passes, and is assembled and arranged on the ceiling 50 in a lattice shape. The grid system is supported by a well-known support frame 52 for ceilings together with other ceiling-arranged devices such as lighting fixtures 53 (see FIG. 1).

この吹出口本体１０は、上部側面に一体に連結するネック部１５を通じてダクト５１から調和空気の供給を受け、開口部１１に導入された調和空気を、空気調和対象の室内空間に面する下部から、気流案内体３０による案内を経て、室内空間に吹出す仕組みである。   This blower outlet body 10 is supplied with conditioned air from a duct 51 through a neck portion 15 that is integrally connected to the upper side surface, and the conditioned air introduced into the opening 11 from the lower portion facing the indoor space to be air conditioned. It is a mechanism that blows out into the indoor space through guidance by the airflow guide 30.

吹出口本体１０側面のネック部１５は、略楕円形、より厳密には長軸方向端部の半円形部分に挟まれた中間部分の外縁を直線状とする長円形の開口断面形状とされる筒体であり、天井５０内で調和空気供給用のダクト５１と接続される構成である。このネック部１５が長円形の開口断面形状を有することに伴い、吹出口本体開口部１１の長辺方向の端部にもネック部１５の開口を十分に近付けることができ、こうした従来の円形開口断面形状のネック部から離れて調和空気の気流が到達しにくかったような箇所にも、調和空気を到達させやすい仕組みである。   The neck portion 15 on the side surface of the outlet body 10 has a substantially elliptical shape, more precisely, an elliptical opening cross-sectional shape in which the outer edge of the intermediate portion sandwiched between the semicircular portions at the ends in the major axis direction is linear. It is a cylindrical body and is configured to be connected to a duct 51 for supplying conditioned air within the ceiling 50. As the neck portion 15 has an oval opening cross-sectional shape, the opening of the neck portion 15 can be sufficiently brought close to the end portion of the outlet body opening portion 11 in the long side direction. It is a mechanism that makes it easy to reach the conditioned air even at a location where it is difficult for the conditioned air flow to reach away from the neck portion of the cross-sectional shape.

また、略箱状をなす吹出口本体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１２が形成される構成である。この額縁部１２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。この額縁部１２が、公知の取付用プレートを介して、あるいは直接、支持枠５２に取付けられることで、吹出口本体１０は天井５０に固定される仕組みである。   Moreover, the frame part 12 which protrudes in the outward direction with respect to the opening part 11 is formed in the edge part by the side of the indoor space of the blower outlet main body 10 which makes a substantially box shape. The frame portion 12 has a substantially hook-like shape in which a portion protruding a predetermined width outwardly on the side opposite to the inner opening portion 11 is continued in the circumferential direction, and its outermost peripheral portion is erected upward. It is the structure made into a shape. The frame body 12 is fixed to the ceiling 50 by being attached to the support frame 52 via a known attachment plate or directly.

前記気流案内体３０は、矩形状の外枠３１とその内側を仕切る複数の仕切板３２とを有し、さらにこれら外枠３１と仕切板３２で囲まれる複数の領域ごとに、それぞれ単位案内部３０ａ、〜、３０ｊとして、複数の略板状の案内羽根３３を、それぞれ前記各領域を横断する配置で、横方向に所定間隔を空けて平行に並べて取付けられ、且つこれら複数の案内羽根３３の組からなる各単位案内部３０ａ、〜、３０ｊを互いに向きの異なる配置とされる状態で、吹出口本体１０内側の開口部１１における室内空間寄り位置に配設される構成である。   The airflow guide body 30 includes a rectangular outer frame 31 and a plurality of partition plates 32 that divide the inside of the rectangular outer frame 31, and each unit guide portion is provided for each of a plurality of regions surrounded by the outer frame 31 and the partition plates 32. 30a to 30j, a plurality of substantially plate-like guide vanes 33 are arranged in parallel to each other at predetermined intervals in the lateral direction in an arrangement crossing the respective regions, and the plurality of guide vanes 33 The unit guide portions 30a to 30j made of a set are arranged at positions closer to the indoor space in the opening 11 inside the air outlet body 10 in a state where the directions of the unit guide portions 30a to 30j are different from each other.

詳細には、気流案内体３０の単位案内部３０ａ、３０ｂ、３０ｃ、３０ｄ、３０ｅ、３０ｆ、３０ｇ、３０ｈ、３０ｉ、３０ｊは、吹出口本体１０の矩形の開口部１１を外枠３１と仕切板３２で長辺方向に五つ、短辺方向に二つ、それぞれ分割して生じた十個の領域に、それぞれ設けられる構成である。言い替えると、十個の単位案内部３０ａ、〜、３０ｊが、開口部１１全体にわたって隙間無く並べて配置された状態となっている。気流案内体３０は、これら単位案内部をなす案内羽根３３間の空気通路部分に調和空気を通過させつつ、調和空気を各単位案内部の案内羽根３３の並んだ向きにそれぞれ案内することとなる。   Specifically, the unit guide portions 30a, 30b, 30c, 30d, 30e, 30f, 30g, 30h, 30i, and 30j of the airflow guide 30 are formed by connecting the rectangular opening 11 of the outlet body 10 to the outer frame 31 and the partition plate. This is a configuration provided in ten regions generated by dividing each of the two in 32 in the long side direction and two in the short side direction. In other words, ten unit guide portions 30a to 30j are arranged side by side with no gap over the entire opening 11. The air flow guide body 30 guides the conditioned air in the direction in which the guide blades 33 of the unit guide portions are arranged while allowing the conditioned air to pass through the air passage portion between the guide blades 33 forming the unit guide portions. .

前記気流案内体３０では、特に、モジュール８０の四つの外辺のうち前記所定の隅部８５を挟む第一の外辺８１及び第二の外辺８２に近い部位の五つの単位案内部３０ｆ、〜、３０ｊを、第一の外辺８１及び／又は第二の外辺８２に向けて気流を案内するものとされる。   In the air flow guide body 30, in particular, five unit guide portions 30 f in portions close to the first outer side 81 and the second outer side 82 sandwiching the predetermined corner portion 85 among the four outer sides of the module 80, To 30j are guided toward the first outer side 81 and / or the second outer side 82.

加えて、気流案内体３０の前記五つの単位案内部３０ｆ、〜、３０ｊの大きさと、気流案内体の他の単位案内部３０ａ、〜、３０ｅの大きさとを所定割合に設定することで、気流案内体の前記五つの単位案内部３０ｆ、〜、３０ｊから第一の外辺８１及び／又は第二の外辺８２に向けて吹出される調和空気（以降、調和空気副部と呼称する）の吹出し量を、この調和空気副部の気流が、第一の外辺８１及び第二の外辺８２寄りの吹出口本体１０外縁の額縁部１２に到達可能とする一方で、気流案内体３０の前記他の単位案内部３０ａ、〜、３０ｅから吹出される調和空気（以降、調和空気主部と呼称する）に調和空気副部が誘引されて、最終的に調和空気主部と同じ方へ進行するように、調和空気主部の吹出し量より小さい所定量、としている。   In addition, by setting the sizes of the five unit guide portions 30f to 30j of the airflow guide body 30 and the sizes of the other unit guide portions 30a to 30e of the airflow guide body to a predetermined ratio, The conditioned air (hereinafter referred to as the conditioned air sub-portion) blown out from the five unit guide portions 30f to 30j of the guide body toward the first outer side 81 and / or the second outer side 82. While the airflow of the conditioned air sub-portion is allowed to reach the frame portion 12 on the outer edge of the outlet body 10 near the first outer side 81 and the second outer side 82, The conditioned air sub-part is attracted to the conditioned air (hereinafter referred to as conditioned air main part) blown out from the other unit guide parts 30a to 30e, and finally proceeds in the same direction as the conditioned air main part. So that it is smaller than the blowout amount of the main part of the conditioned air. .

言い替えると、気流案内体３０の前記五つの単位案内部３０ｆ、〜、３０ｊから、第一の外辺８１及び／又は第二の外辺８２に向けて吹出される調和空気副部の量が、この調和空気副部の気流が前記第一の外辺８１及び第二の外辺８２寄りの吹出口本体１０外縁の額縁部１２に到達しつつ、他方向に向かう調和空気主部の気流に誘引されて進行方向を変え、最終的にはモジュール８０の三つの隅部８６、８７、８８と吹出口装置１とに囲まれた領域９０の方へ向かうものとなるように、気流案内体３０における前記五つの単位案内部３０ｆ、〜、３０ｊの大きさを設定することとなる。   In other words, the amount of the conditioned air sub-portion that is blown out from the five unit guide portions 30f to 30j of the airflow guide body 30 toward the first outer side 81 and / or the second outer side 82 is The air flow of the conditioned air sub-portion reaches the frame portion 12 on the outer edge of the outlet body 10 near the first outer side 81 and the second outer side 82 and is attracted to the air flow of the main portion of the conditioned air toward the other direction. In the airflow guide 30 so that the direction of travel is changed and the direction toward the region 90 surrounded by the three corners 86, 87, 88 of the module 80 and the air outlet device 1 is finally reached. The sizes of the five unit guide portions 30f to 30j are set.

具体的には、単位案内部３０ａ、〜、３０ｅと単位案内部３０ｆ、〜、３０ｊとが、それぞれ吹出口本体１０の矩形開口部１１の長辺方向と短辺方向で一様な大きさとなっている場合、吹出口本体１０の矩形開口部１１の短辺方向における、第一の外辺８１寄りの単位案内部３０ｆ、〜、３０ｊの大きさと、第三の外辺８３寄りの単位案内部３０ａ、〜、３０ｅの大きさとの割合が、例えば１：２．４程度となるように設定される。   Specifically, the unit guide portions 30a to 30e and the unit guide portions 30f to 30j have a uniform size in the long side direction and the short side direction of the rectangular opening 11 of the outlet body 10, respectively. The size of the unit guide portions 30f to 30j near the first outer side 81 and the unit guide portion near the third outer side 83 in the short side direction of the rectangular opening 11 of the outlet body 10 The ratio of the size of 30a to 30e is set to be about 1: 2.4, for example.

なお、単位案内部３０ａ、〜、３０ｊは開口部１１を長辺方向に五つに等分割し、且つ短辺方向に所定割合で二つに分割した大きさとして気流案内体３０にそれぞれ設定しているが、数や大きさの設定はこれに限られるものではなく、長辺方向も不等分割とした形状としたり、単位案内部ごとに大きさが異なるようにすることもでき、例えば、第一の外辺８１寄りの単位案内部と第三の外辺８３寄りの単位案内部とで数を異ならせるようにしてもよい。   The unit guide portions 30a to 30j are respectively set to the airflow guide body 30 as a size obtained by equally dividing the opening 11 into five in the long side direction and dividing it into two at a predetermined ratio in the short side direction. However, the setting of the number and size is not limited to this, and the shape of the long side direction may be unequally divided, or the size may be different for each unit guide part. The number of unit guides near the first outer side 81 may be different from the number of unit guides near the third outer side 83.

気流案内体３０における各案内羽根３３は、細長い矩形状の薄板を、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り、板状の外枠３１又は仕切板３２に長手方向両端部を固定されて複数配設され、案内羽根３３同士の平行に複数並んだ並び方向を気流案内方向とされる。   Each guide vane 33 in the airflow guide body 30 is a long and thin rectangular plate formed so that a cross-sectional shape perpendicular to the longitudinal direction is curved and has a rounded shape as a whole. A plurality of both end portions in the longitudinal direction are fixed to the outer frame 31 or the partition plate 32, and a plurality of parallel arrangements of the guide blades 33 are defined as an air flow guide direction.

気流案内体３０の各単位案内部３０ａ、〜、３０ｊにおいて、気流案内方向、すなわち、平行に並ぶ複数の案内羽根３３の並ぶ向きは、単位案内部３０ａ、〜、３０ｊごとに独立した設定とされ、単位案内部３０ａ、〜、３０ｊごとに異ならせる他、必要に応じて一又は複数を同じ気流案内方向として形成するようにしてもかまわない。   In each of the unit guide portions 30a to 30j of the airflow guide body 30, the airflow guide direction, that is, the direction in which the plurality of guide blades 33 arranged in parallel is set independently for each of the unit guide portions 30a to 30j. In addition to making the unit guide portions 30a to 30j different, one or a plurality of unit guide portions 30a to 30j may be formed as the same air flow guide direction as necessary.

各単位案内部のうち、モジュール８０の第二の辺８２に最も近い単位案内部３０ａからは、前記第三の辺８３に向けて気流が案内される。すなわち、第一の単位案内部３０ａでは、案内羽根３３の並ぶ方向が開口部短辺方向に対し時計回りに若干傾いた向き、例えば２０°傾いた向き、となっており、調和空気主部の気流は、開口部１１から案内羽根３３間を通って吹出した後、他の単位案内部からの吹出しの影響も受けて、モジュール８０の第二の辺８２に沿って進んで拡散しながら、第三の辺８３のうち第二の辺８２に近い部位に向うこととなる。   Of each unit guide, the air flow is guided from the unit guide 30 a closest to the second side 82 of the module 80 toward the third side 83. That is, in the first unit guide portion 30a, the direction in which the guide vanes 33 are arranged is slightly inclined clockwise with respect to the short side direction of the opening, for example, 20 °. After the air flow is blown out from the opening 11 through the guide blades 33, the air flow is also affected by the blowout from other unit guides, and proceeds along the second side 82 of the module 80 while diffusing. Of the three sides 83, it will be directed to a part close to the second side 82.

続いて、第二の単位案内部３０ｂでは、案内羽根３３の並ぶ方向が開口部短辺方向に対し反時計回りに若干傾いた向き、例えば１０°傾いた向き、となっており、前記第一の単位案内部３０ａからの吹出方向とは、３０°ずれた向きへの吹出しとなる。この第二の単位案内部３０ｂでは、調和空気主部の気流は、開口部１１から案内羽根３３間を通って吹出した後、他の単位案内部からの吹出しの影響も受けつつ、モジュール８０の第三の辺８３側に進んで拡散し、第三の辺８３の中間部位辺りに向うこととなる。   Subsequently, in the second unit guide portion 30b, the direction in which the guide vanes 33 are arranged is slightly inclined counterclockwise with respect to the short side direction of the opening, for example, 10 °, The blowing direction from the unit guide part 30a is blowing in a direction shifted by 30 °. In the second unit guide portion 30b, the airflow of the conditioned air main portion is blown out from the opening 11 through the guide blades 33, and then influenced by the blowout from the other unit guide portions. The light travels toward the third side 83 and diffuses toward the middle part of the third side 83.

第三の単位案内部３０ｃでは、案内羽根３３の並ぶ方向が前記第二の単位案内部３０ｂにおける案内羽根３３の並ぶ方向からさらに反時計回りに若干ずれた向き、例えば、開口部短辺方向に対し反時計回りに４５°傾いた向き、となっており、前記第二の単位案内部３０ｂからの吹出方向とは３５°ずれた向きへの吹出しとなる。この第三の単位案内部３０ｃでは、調和空気主部の気流は、開口部１１から案内羽根３３間を通って吹出した後、他の単位案内部からの吹出しの影響も受けつつ、モジュール８０の第三の辺８３側に進んで拡散し、第三の辺８３のうちその中間部位より第四の辺８４側に寄った部位辺りに向うこととなる。   In the third unit guide portion 30c, the direction in which the guide vanes 33 are arranged is slightly shifted counterclockwise from the direction in which the guide vanes 33 are arranged in the second unit guide portion 30b, for example, in the short side direction of the opening. In contrast, the direction is inclined 45 ° counterclockwise, and the air is blown out in a direction shifted by 35 ° from the blowing direction from the second unit guide portion 30b. In the third unit guide portion 30c, the airflow of the conditioned air main portion is blown out from the opening 11 through the guide blades 33 and then influenced by the blowout from the other unit guide portions. It will spread toward the third side 83 and diffuse, and will be directed to the part of the third side 83 that is closer to the fourth side 84 than the intermediate part.

第四の単位案内部３０ｄでは、案内羽根３３の並ぶ方向が前記第三の単位案内部３０ｃにおける案内羽根３３の並ぶ方向からさらに反時計回りに若干ずれた向き、例えば、開口部短辺方向に対し反時計回りに７５°傾いた向き、となっており、前記第三の単位案内部３０ｃからの吹出方向とは３０°ずれた向きへの吹出しとなる。この第四の単位案内部３０ｄでは、調和空気主部の気流は、開口部１１から案内羽根３３間を通って吹出した後、他の単位案内部からの吹出しの影響も受けつつ、モジュール８０の第四の辺８４側に進んで拡散し、第四の辺８４のうち第三の辺８３に近い部位に向うこととなる。   In the fourth unit guide portion 30d, the direction in which the guide vanes 33 are arranged is slightly shifted counterclockwise from the direction in which the guide vanes 33 are arranged in the third unit guide portion 30c, for example, in the short side direction of the opening. In contrast, the direction is inclined by 75 ° counterclockwise, and the air is blown in a direction shifted by 30 ° from the blowing direction from the third unit guide portion 30c. In the fourth unit guide portion 30d, the air current of the conditioned air main portion is blown from the opening 11 through the guide blades 33, and then influenced by the blowout from the other unit guide portions. The fourth side 84 diffuses toward the fourth side 84 and is directed to a portion of the fourth side 84 that is close to the third side 83.

そして、第五の単位案内部３０ｅでは、案内羽根３３の並ぶ方向が、開口部短辺方向に対し反時計回りに９０°回転して直交する向きからさらに反時計回りに若干ずれた向き、例えば、開口部短辺方向に対し反時計回りに１０５°傾いた向きとなっており、前記第四の単位案内部３０ｄからの吹出方向とは３０°ずれた向きへの吹出しとなる。この第五の単位案内部３０ｅでは、調和空気主部の気流は、開口部１１から案内羽根３３間を通って吹出した後、他の単位案内部からの吹出しの影響も受けつつ、モジュール８０の第四の辺８４側に進んで拡散し、第四の辺８４のうちその中間部位より第一の辺８１側に寄った部位辺りに向うこととなる。   In the fifth unit guide portion 30e, the direction in which the guide blades 33 are arranged is rotated by 90 ° counterclockwise with respect to the short side direction of the opening and is slightly deviated counterclockwise from the orthogonal direction, for example, The direction is inclined by 105 ° counterclockwise with respect to the short side direction of the opening, and the air is blown in a direction deviated by 30 ° from the blowing direction from the fourth unit guide portion 30d. In the fifth unit guide part 30e, the air current of the conditioned air main part is blown out from the opening 11 through the guide blades 33, and then influenced by the blowout from the other unit guide parts. It will diffuse toward the fourth side 84 side, and will be directed to the part of the fourth side 84 that is closer to the first side 81 side than the intermediate part.

一方、照明器具５３に近い側で、モジュール８０の第二の辺８２に最も近い第六の単位案内部３０ｆでは、案内羽根３３の並ぶ方向が、開口部短辺方向に対し時計回りに９０°以上回転してずれた向き、例えば、開口部短辺方向に対し時計回りに９０°傾いて直交する向きとなっており、調和空気副部の気流は、開口部１１から案内羽根３３間を通って吹出した後、モジュール８０の第二の辺８２側に進んで吹出口本体１０の額縁部１２を越えるよう拡散しつつも、他の単位案内部からの調和空気主部吹出しの影響を受けて誘引され、最終的には大部分が第三の辺８３の方へ向うこととなる。そのため、モジュールの第二の辺８２の位置に壁が配置される場合でも、壁の影響を受けて気流が偏ることはない。   On the other hand, in the sixth unit guide portion 30f closest to the second side 82 of the module 80 on the side close to the lighting fixture 53, the direction in which the guide vanes 33 are arranged is 90 ° clockwise relative to the short side direction of the opening. The direction shifted by the above rotation, for example, the direction inclined 90 ° clockwise with respect to the short side direction of the opening is orthogonal, and the airflow of the conditioned air sub-part passes between the opening 11 and the guide vanes 33. After being blown out, it proceeds to the second side 82 side of the module 80 and diffuses beyond the frame portion 12 of the outlet main body 10, but is affected by the conditioned air main portion blowout from other unit guide portions. At the end of the course, most will be directed towards the third side 83. Therefore, even when the wall is arranged at the position of the second side 82 of the module, the airflow is not biased by the influence of the wall.

また、同じ照明器具５３に近い側の、第七の単位案内部３０ｇでは、案内羽根３３の並ぶ方向が、前記第六の単位案内部３０ｆにおける案内羽根３３の並ぶ方向と同じか、さらに時計回りにずれた向き、例えば、開口部短辺方向に対し時計回りに１５０°傾いた向きとなっている。この第七の単位案内部３０ｇでは、調和空気副部の気流は、開口部１１から案内羽根３３間を通って吹出した後、モジュール８０の第一の辺８１と第二の辺８２間の隅部側に進んで吹出口本体１０の額縁部１２を越えるよう拡散しつつも、他の単位案内部からの調和空気主部吹出しの影響を受けて誘引され、最終的には大部分が第三の辺８３の方へ向うこととなる。そのため、モジュールの第一の辺８１や第二の辺８２の位置に壁が配置される場合でも、壁の影響を受けて気流が偏ることはない。   In the seventh unit guide portion 30g on the side close to the same lighting fixture 53, the direction in which the guide vanes 33 are arranged is the same as the direction in which the guide vanes 33 are arranged in the sixth unit guide portion 30f, or further clockwise. For example, the direction is inclined by 150 ° clockwise with respect to the short side direction of the opening. In the seventh unit guide portion 30g, the airflow of the conditioned air sub-portion blows out from the opening portion 11 through the guide blades 33, and then the corner between the first side 81 and the second side 82 of the module 80. It is attracted by the influence of the conditioned air main part blowout from the other unit guide parts, and finally the third part is mostly the third while diffusing to go to the part side and beyond the frame part 12 of the outlet body 10. It will be directed toward the side 83. Therefore, even when a wall is arranged at the position of the first side 81 or the second side 82 of the module, the airflow is not biased by the influence of the wall.

同じく、第八の単位案内部３０ｈでは、案内羽根３３の並ぶ方向が、前記第七の単位案内部３０ｇにおける案内羽根３３の並ぶ方向と同じか、さらに時計回りに大きくずれた向き、例えば、開口部短辺方向に対し時計回りに１６５°傾いた向きとなっている。この第八の単位案内部３０ｈでは、調和空気副部の気流は、開口部１１から案内羽根３３間を通って吹出した後、モジュール８０の第一の辺８１側に進んで吹出口本体１０の額縁部１２を越えるよう拡散しつつも、他の単位案内部からの調和空気主部吹出しの影響を受けて誘引され、最終的には大部分が第三の辺８３や第四の辺８４の方へ向うこととなる。そのため、モジュールの第一の辺８１の位置に壁が配置される場合でも、壁の影響を受けて気流が偏ることはない。   Similarly, in the eighth unit guide portion 30h, the direction in which the guide vanes 33 are arranged is the same as the direction in which the guide vanes 33 are arranged in the seventh unit guide portion 30g, or a direction greatly deviated clockwise, for example, an opening The direction is inclined 165 ° clockwise relative to the short side direction. In the eighth unit guide portion 30h, the airflow of the conditioned air sub-portion is blown out from the opening portion 11 through the guide vanes 33, and then proceeds to the first side 81 side of the module 80 to reach the outlet body 10. While spreading beyond the frame portion 12, it is attracted by the influence of the conditioned air main part blowout from other unit guide parts, and finally most of the third side 83 and the fourth side 84 Will be headed towards. Therefore, even when the wall is arranged at the position of the first side 81 of the module, the airflow is not biased due to the influence of the wall.

同じく、第九の単位案内部３０ｉでは、案内羽根３３の並ぶ方向が、開口部短辺方向に対し反時計回りに９０°回転して直交する向きからさらに反時計回りに大きくずれた向き、例えば、開口部短辺方向に対し反時計回りに１６５°傾いた向きとなっている。この第九の単位案内部３０ｉでは、調和空気副部の気流は、開口部１１から案内羽根３３間を通って吹出した後、モジュール８０の第一の辺８１側に進んで吹出口本体１０の額縁部１２を越えるよう拡散しつつも、他の単位案内部からの調和空気主部吹出しの影響を受けて誘引され、最終的には大部分が第四の辺８４の方へ向うこととなる。そのため、モジュールの第一の辺８１の位置に壁が配置される場合でも、壁の影響を受けて気流が偏ることはない。   Similarly, in the ninth unit guide portion 30i, the direction in which the guide vanes 33 are arranged is rotated 90 ° counterclockwise with respect to the short side direction of the opening and is further shifted counterclockwise from the orthogonal direction, for example, The direction is inclined 165 ° counterclockwise with respect to the short side direction of the opening. In the ninth unit guide portion 30i, the airflow of the conditioned air sub-portion blows out from the opening portion 11 through the guide blades 33, and then proceeds to the first side 81 side of the module 80 to reach the outlet body 10. While diffusing beyond the frame portion 12, it is attracted by the influence of the conditioned air main part blowout from the other unit guide parts, and finally the majority is directed toward the fourth side 84. . Therefore, even when the wall is arranged at the position of the first side 81 of the module, the airflow is not biased due to the influence of the wall.

そして、第十の単位案内部３０ｊでは、案内羽根３３の並ぶ方向が、前記第九の単位案内部３０ｉにおける案内羽根３３の並ぶ方向と同じか、時計回りにずれた向き、例えば、開口部短辺方向に対し反時計回りに１５０°傾いた向きとなっている。この第十の単位案内部３０ｊでは、調和空気副部の気流は、開口部１１から案内羽根３３間を通って吹出した後、モジュール８０の第一の辺８１と第四の辺８４間の隅部側に進んで吹出口本体１０の額縁部１２を越えるよう拡散しつつも、他の単位案内部からの調和空気主部吹出しの影響を受けて誘引され、最終的には大部分が第四の辺８４の方へ向うこととなる。そのため、モジュールの第一の辺８１の位置に壁が配置される場合でも、壁の影響を受けて気流が偏ることはない。   In the tenth unit guide portion 30j, the direction in which the guide vanes 33 are arranged is the same as the direction in which the guide vanes 33 are arranged in the ninth unit guide portion 30i, or is shifted in the clockwise direction, for example, the opening portion is short. The direction is inclined by 150 ° counterclockwise with respect to the side direction. In the tenth unit guide portion 30j, the air flow of the conditioned air sub-portion blows out from the opening portion 11 through the guide blades 33, and then the corner between the first side 81 and the fourth side 84 of the module 80. It is attracted by the influence of the conditioned air main part blowout from the other unit guide parts, and finally the majority is the fourth while diffusing so as to proceed to the part side and exceed the frame part 12 of the outlet body 10. It will be headed toward the side 84. Therefore, even when the wall is arranged at the position of the first side 81 of the module, the airflow is not biased due to the influence of the wall.

こうして、モジュール８０の第一の辺８１に近い側の各単位案内部３０ｆ、３０ｇ、３０ｈ、３０ｉ、３０ｊによる調和空気副部の気流案内方向を、第一の辺８１から遠い側の各単位案内部３０ａ、３０ｂ、３０ｃ、３０ｄ、３０ｅによる調和空気主部の気流案内方向に対して、上記で示したように、調和空気副部の気流が吹出口本体１０の第一の辺８１に近い部分の額縁部１２各位置を越えて進行するように設定する一方、これら単位案内部３０ｆ、〜、３０ｊにおける調和空気副部の吹出し量は、第一の辺８１から遠い側の各単位案内部３０ａ、〜、３０ｅにおける調和空気主部の吹出し量に対し半分より少なくしていることで、これら単位案内部３０ｆ、〜、３０ｊからの調和空気副部の吹出気流は、気流が額縁部１２を越えた以降は、第一の辺８１から遠い側の各単位案内部３０ａ、〜、３０ｅからの調和空気主部の吹出気流の誘引によりこれらの吹出気流と一体化する程度のものとなっており、気流の壁への貼り付きや吹出口直下への進行によるドラフトなど、居住域に対し悪影響を及ぼすようなことはない。   Thus, the airflow guidance direction of the conditioned air sub-portion by the unit guide portions 30f, 30g, 30h, 30i, 30j on the side close to the first side 81 of the module 80 is set to each unit guide on the side far from the first side 81. As shown above with respect to the airflow guiding direction of the conditioned air main portion by the portions 30a, 30b, 30c, 30d, and 30e, the airflow of the conditioned air sub-portion is close to the first side 81 of the outlet body 10 On the other hand, the amount of blowout of the conditioned air sub-portion in each of the unit guide portions 30f to 30j is set so that each unit guide portion 30a on the far side from the first side 81 The amount of air blown from the conditioned air sub-portion from these unit guide portions 30f, 30j, 30j is less than half the amount of air blown from the conditioned air main portion at 30e, 30e. After The unit guide portions 30a to 30e on the side far from the first side 81 are integrated with these blown airflows by the induction of the blown airflow of the conditioned air main part from the unit air guides 30a to 30e. There will be no adverse effects on the living area, such as sticking or drafting by proceeding directly under the outlet.

気流案内体３０の単位案内部３０ａ、〜、３０ｊが、各単位案内部３０ａ、〜、３０ｊごとに気流を案内する向きを個別に設定され、特に、主要な単位案内部３０ａ、〜、３０ｅで案内された調和空気主部の吹出気流が、モジュール８０における、前記所定の隅部８５を除くモジュールの三つの隅部８６、８７、８８と吹出口装置１とに囲まれた領域９０で、吹出口装置１を中心に放射状に進行することで、それぞれの吹出気流が相互に誘引等の影響を及して合成気流となり、前記領域９０で単独の吹出気流の到達範囲より広い範囲に拡散していくこととなる。   The direction in which the unit guide portions 30a to 30j of the airflow guide 30 guide the airflow is set individually for each unit guide portion 30a to 30j. In particular, in the main unit guide portions 30a to 30e. The blown airflow of the guided conditioned air main part is blown in a region 90 surrounded by the three corners 86, 87, 88 of the module excluding the predetermined corner 85 and the outlet device 1 in the module 80. By proceeding radially with the outlet device 1 as the center, each blown airflow has a mutual influence such as attraction and becomes a synthetic airflow, which diffuses in the region 90 to a wider range than the reach of the single blown airflow. Will go.

前記制御板２０は、調和空気の通過可能な開口孔２１を複数穿設される薄板で形成され、気流案内体３０の上側に重ねて配設され、気流案内体３０における案内羽根３３間の空気通路部分への調和空気の進入を一部制限する構成である。   The control plate 20 is formed of a thin plate having a plurality of opening holes 21 through which conditioned air can pass, and is disposed on the upper side of the airflow guide 30 so that air between the guide vanes 33 in the airflow guide 30 is formed. It is the structure which restrict | limits a part of approach of the conditioned air to a channel | path part.

詳細には、制御板２０は、気流案内体３０における案内羽根３３間の空気通路部分上部のうち、各案内羽根３３の上端から気流案内方向の前側所定範囲に開口孔２１をそれぞれ位置させる一方、各案内羽根３３の上端から気流案内方向の後側所定範囲には非開口部分を位置させて、案内羽根３３間の空気通路部分上部を一部塞ぐような孔配置形状とされる。そして、制御板２０における各開口孔２１を位置させる前記気流案内方向前側所定範囲は、具体的には、図５に示すように、各案内羽根３３における上端位置より気流案内方向の前側で、且つ下端位置より気流案内方向の後側となる範囲としており、開口孔２１は案内羽根３３の上方に位置する。 Specifically, the control plate 20 positions the opening holes 21 in the front predetermined range in the airflow guide direction from the upper end of each guide blade 33 in the upper part of the air passage portion between the guide blades 33 in the airflow guide 30, A non-opening portion is positioned in a predetermined range on the rear side of the airflow guide direction from the upper end of each guide blade 33, and a hole arrangement shape is formed so as to partially block the upper portion of the air passage portion between the guide blades 33. The predetermined range on the front side of the airflow guide direction in which each opening hole 21 in the control plate 20 is positioned is specifically, on the front side in the airflow guide direction from the upper end position of each guide blade 33, and as shown in FIG. The opening hole 21 is located above the guide vane 33 in a range that is on the rear side of the airflow guide direction from the lower end position.

こうして、制御板２０の各開口孔２１が案内羽根３３の上面の近くに位置して、流路断面積を絞って調和空気の流速を高めつつ、調和空気を適切に案内羽根３３の上面に導いてこれに沿わせる一方、非開口部分で調和空気が案内羽根３３に沿わずに空気通路部分を下方へ進行するのを抑えられる。これにより、調和空気に対する案内羽根３３の横方向への案内性能を十分に発揮させることができ、調和空気の気流を確実に横向きに吹き出せることとなり、室内空気との温度差で下降しやすい低温の調和空気の場合でも、吹出気流の横方向への到達距離を十分に確保できる。   Thus, each opening hole 21 of the control plate 20 is positioned near the upper surface of the guide vane 33, and the conditioned air is appropriately guided to the upper surface of the guide vane 33 while reducing the cross-sectional area of the flow path to increase the flow rate of the conditioned air. On the other hand, it is possible to prevent the conditioned air from traveling downward along the air passage portion without following the guide vanes 33 in the non-opening portion. As a result, the guide performance of the guide vanes 33 in the lateral direction with respect to the conditioned air can be sufficiently exerted, and the air flow of the conditioned air can be blown out in a lateral direction, and the low temperature is likely to drop due to a temperature difference from the room air. Even in the case of conditioned air, it is possible to secure a sufficient distance in the lateral direction of the blown airflow.

制御板２０の各開口孔２１は、全体として、吹出口から吹出す空気量を大とする場合には大きく、また、空気量を小とする場合には小さくするか、一部の開口孔を穿設せずに閉じたものとするなど、吹出し空気量に応じた開口面積とされる。   Each of the opening holes 21 of the control plate 20 as a whole is large when the amount of air blown out from the outlet is large, and is small when the amount of air is small, or a part of the opening holes. The opening area is determined according to the amount of blown air, for example, it is closed without being drilled.

この制御板の各開口孔の大きさを、環境ごとの調和空気の多様な要求量や、調和空気の略水平各方向への吹出しパターンに合わせて調整し、最適な開口面積を設定することにより、適切な空気量を得るだけにとどまらず、案内羽根３３で案内される調和空気の気流速度を安定させることができる。このように開口孔２１の大きさを調整する他に、開口孔の位置や孔形状の微調整を行うことでも、同様の効果を得ることができる。   By adjusting the size of each opening hole of this control plate according to various requirements of conditioned air for each environment and the blowing pattern of conditioned air in almost horizontal directions, and setting the optimal opening area In addition to obtaining an appropriate amount of air, the flow velocity of the conditioned air guided by the guide vanes 33 can be stabilized. In addition to adjusting the size of the opening hole 21 in this way, the same effect can be obtained by finely adjusting the position and shape of the opening hole.

なお、制御板２０の使用に際しては、あらかじめ吹出し空気量に合わせた複数種類の大きさの開口孔をそれぞれ穿設した複数の制御板を用意して、実際の設置箇所における吹出口装置の使用空気量に合わせた開口孔の制御板を選択して用いるようにすることができる。   When the control plate 20 is used, a plurality of control plates each provided with a plurality of types of opening holes according to the amount of blown air are prepared in advance, and the air used by the blowout device at the actual installation location is prepared. It is possible to select and use a control plate having an aperture according to the amount.

前記化粧グリル４０は、調和空気を抵抗なく通過させられる大きさの多数の孔４１を所定の規則的配置で穿設される略板状体であり、吹出口本体１０の開口部１１及び気流案内体３０を覆い隠すようにして、吹出口本体１０の室内側端部に取付けられるものである。この化粧グリル４０の孔４１は十分な大きさで多数穿設され、化粧グリル４０は開口率を大きく設定されていることから、内側の気流案内体３０を室内側から見えにくくしつつ、気流案内体３０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。
なお、化粧グリルの孔形状は図１に示すような正方形に限られるものではなく、矩形や六角形などの多角形、円や楕円等、他の形状としてもかまわない。 The decorative grill 40 is a substantially plate-like body in which a large number of holes 41 sized to allow conditioned air to pass without resistance are formed in a predetermined regular arrangement, and the opening 11 of the outlet body 10 and the airflow guide. The body 30 is attached to the indoor side end of the outlet body 10 so as to cover the body 30. A large number of holes 41 of the decorative grill 40 are formed with a sufficient size, and the decorative grill 40 is set to have a large opening ratio. Therefore, the air flow guide 30 is made difficult to see from the indoor side while the air flow guide 30 is made invisible. It does not affect the blowout of the conditioned air flow guided by the body 30.
The hole shape of the decorative grill is not limited to a square as shown in FIG. 1, but may be other shapes such as a polygon such as a rectangle or a hexagon, a circle or an ellipse.

次に、前記構成に基づく吹出口装置における気流案内状態について説明する。ダクト５１から供給された調和空気は、吹出口装置１のネック部１５を通じてスムーズに吹出口本体１０の開口部１１へ進行し、矩形状の開口部１１に配置された制御板２０の開口孔２１を通って、さらに室内空間寄りに位置する気流案内体３０に到達する。   Next, the airflow guiding state in the air outlet device based on the above configuration will be described. The conditioned air supplied from the duct 51 smoothly proceeds to the opening 11 of the outlet body 10 through the neck portion 15 of the outlet device 1, and the opening hole 21 of the control plate 20 disposed in the rectangular opening 11. It passes through and reaches the airflow guide 30 that is located closer to the indoor space.

気流案内体３０に達した調和空気は、気流案内体３０の各単位案内部３０ａ、〜、３０ｊにおける案内羽根３３間の空気通路部分を進むが、制御板２０の開口孔２１が空気通路部分の一部にのみ通じていることから、調和空気は各案内羽根３３の上面に沿って流れ、案内羽根３３による案内の影響を強く受ける状態となり、案内羽根形状に従って横向きの速度成分を大きくした気流となる。   The conditioned air that has reached the airflow guide 30 travels through the air passage portion between the guide blades 33 in the unit guide portions 30a to 30j of the airflow guide body 30, but the opening hole 21 of the control plate 20 is the air passage portion. Since only a part of the air is conditioned, the conditioned air flows along the upper surface of each guide vane 33 and is strongly affected by the guidance of the guide vane 33. Become.

そして、調和空気は、各単位案内部３０ａ、〜、３０ｊでそれぞれ所定方向に並んだ案内羽根３３に案内されて、これら案内羽根３３の並んだ方向に進み、さらに化粧グリル４０の孔４１を経て、室内空間に横向きに吹出す。   The conditioned air is guided by the guide blades 33 arranged in a predetermined direction by the unit guide portions 30a to 30j, proceeds in the direction in which the guide blades 33 are arranged, and further passes through the holes 41 of the decorative grill 40. , Blow out sideways into the indoor space.

こうして、調和空気の気流が、気流案内体３０の各単位案内部３０ａ、〜、３０ｊにおける案内羽根３３の配置に従ってそれぞれ案内されて、各方向に向かう中、モジュール８０における吹出口本体１０開口部１１と三つの隅部８６、８７、８８とに囲まれた領域９０において、開口部１１を中心に放射状に進行する状態が得られ、気流同士が相互に影響を与えながら一群の合成気流となって拡散することで、前記領域９０に気流が均等に配分され、モジュール８０の範囲の室内空間全域に吹出気流が拡散する状態となる。すなわち、モジュール８０の隅部８５近傍に偏って配設された吹出口装置１からも、室内空間に対する空気調和を均一に実行できることとなる。   Thus, the air flow of the conditioned air is guided according to the arrangement of the guide vanes 33 in the unit guide portions 30a to 30j of the air flow guide body 30 and is directed in the respective directions. In the region 90 surrounded by the three corners 86, 87, 88, a state of progressing radially about the opening 11 is obtained, and a group of synthetic airflows is formed while the airflows affect each other. By diffusing, the airflow is evenly distributed to the region 90, and the blown airflow is diffused throughout the indoor space in the range of the module 80. In other words, the air conditioning for the indoor space can be performed uniformly from the air outlet device 1 disposed in the vicinity of the corner 85 of the module 80.

また、単位案内部３０ａ、〜、３０ｊのうち、第一の辺８１に近い各単位案内部３０ｆ、〜、３０ｊから、調和空気副部が吹出口本体１０における第一の辺８１に近い部位の額縁部１２を越えて進むように吹出すことで、いずれの方向についても、吹出口本体１０外縁の額縁部１２をはじめとする吹出口本体１０の表面や化粧グリル４０が、調和空気の気流により、室内空間の空気から隔離されることとなり、調和空気の吹出しに伴い吹出口付近へ誘引される二次空気と、調和空気で冷やされた吹出口装置１表面各部との接触を阻止でき、吹出口装置１表面各部における結露の発生やこれによる表面の汚染を防ぐことができる。   Further, among the unit guide portions 30a to 30j, from the unit guide portions 30f to 30j that are close to the first side 81, the conditioned air sub-portion is located at a portion that is close to the first side 81 in the outlet body 10. By blowing out beyond the frame part 12, the surface of the outlet body 10 including the frame part 12 on the outer edge of the outlet body 10 and the decorative grille 40 are caused by the flow of conditioned air in any direction. Therefore, it is isolated from the air in the indoor space, and the secondary air attracted to the vicinity of the blowout outlet when the conditioned air is blown out can be prevented from contacting each part of the surface of the blowout outlet device 1 cooled by the conditioned air. Generation | occurrence | production of the dew condensation in each part of the exit apparatus 1 surface, and the contamination of the surface by this can be prevented.

このように、本実施形態に係る低温吹出口装置においては、吹出口本体１０における矩形開口断面の開口部１１に、調和空気の気流を複数の方向にそれぞれ案内する気流案内体３０を配設すると共に、気流案内体３０に重ねて制御板２０を配設し、気流案内体３０への調和空気の流入を制御板２０で調整した上で、気流案内体３０で調和空気の気流を案内して、モジュール８０の所定の隅部近傍における吹出口位置から放射状に気流を進ませることにより、制御板２０が調和空気を適切に案内羽根３３の上面に導いてこれに沿わせ、案内羽根３３の横方向案内性能を十分に発揮させることができ、調和空気の気流を開口部１１から確実に横向きに吹き出して、モジュール８０における三つの隅部８６、８７、８８と吹出口本体１０開口部１１とに囲まれた広範囲の領域に、開口部１１からの吹出気流を拡散させる状態を得られることとなり、低温の調和空気の場合でも横方向の到達距離を十分に確保でき、モジュール８０において吹出口からの気流の到達しない部位が生じにくく、一つの吹出口からモジュール８０のほぼ全域に気流を均等に拡散させて空気調和を実現でき、一モジュールに一つの吹出口を配置すれば足りることとなり、空気調和のコストを抑えられる。また、吹出口を照明器具等の天井配設機器との組合わせで、モジュールの中央でない箇所に配設される状態としても空気調和上の問題を生じることはなく、吹出口も含む全体で調和のとれた天井デザインと空気調和性能との両立が図れる。   As described above, in the low-temperature air outlet device according to the present embodiment, the air flow guide body 30 that guides the air flow of the conditioned air in a plurality of directions is disposed in the opening portion 11 of the rectangular opening cross section in the air outlet body 10. At the same time, the control plate 20 is disposed so as to overlap the airflow guide body 30, and the airflow of the conditioned air is guided by the airflow guide body 30 after the inflow of the conditioned air to the airflow guide body 30 is adjusted by the control plate 20. The control plate 20 appropriately guides the conditioned air to the upper surface of the guide vane 33 along the radial direction from the outlet position in the vicinity of a predetermined corner of the module 80, and the side of the guide vane 33. The direction guidance performance can be sufficiently exhibited, and the air flow of conditioned air is surely blown out laterally from the opening 11, so that the three corners 86, 87, 88 in the module 80 and the blower outlet body 10 opening 11. A state in which the airflow from the opening 11 is diffused can be obtained in a wide area surrounded by the airflow, and a sufficient reach in the lateral direction can be secured even in the case of low-temperature conditioned air. It is difficult to produce a part where the airflow does not reach, and air conditioning can be realized by evenly diffusing the airflow from one outlet to almost the entire area of the module 80, and it is sufficient to arrange one outlet in one module. Reduce the cost of harmony. Moreover, even if the air outlet is combined with a ceiling-arranged device such as a lighting fixture, the air conditioning problem does not occur even if the air outlet is disposed at a location other than the center of the module. A balance between a well-designed ceiling design and air-conditioning performance can be achieved.

なお、前記実施形態に係る低温吹出口装置においては、気流案内体３０が十組の単位案内部３０ａ、〜、３０ｊを有して、吹出口本体１０の矩形状の開口部１１から、各単位案内部３０ａ、〜、３０ｊごとに調和空気の気流をそれぞれ案内して十方向に吹出す構成としているが、この他、気流案内体が十以外の複数組となる単位案内部を有する構成とすることもでき、前記第１の実施形態同様、それぞれの単位案内部ごとに気流を案内する向きを適切に設定することで、各単位案内部で案内された吹出気流が、モジュール８０における、吹出口に近い隅部８５を除くモジュールの三つの隅部８６、８７、８８と吹出口装置とに囲まれた領域９０で、吹出口装置を中心に放射状に進行して、前記領域９０に均等に拡散することができ、モジュール８０の範囲の室内空間全域に空気調和の効果を与えることができる。   In the low-temperature air outlet apparatus according to the embodiment, the airflow guide body 30 has ten sets of unit guide portions 30a to 30j, and each unit from the rectangular opening portion 11 of the air outlet body 10. Although it is set as the structure which guides the airflow of conditioned air for every guide part 30a -... 30j and blows out in ten directions, it is set as the structure which has a unit guide part from which airflow guide bodies become multiple sets other than ten. Similarly to the first embodiment, by appropriately setting the direction in which the air flow is guided for each unit guide unit, the blown air flow guided by each unit guide unit is In a region 90 surrounded by the three corners 86, 87, 88 of the module excluding the corner portion 85 close to the air outlet device and the air outlet device, it progresses radially around the air outlet device and diffuses evenly in the region 90 Can be modular The open spaces in the range of 80 can give the effect of air-conditioning.

また、前記実施形態に係る低温吹出口装置においては、気流案内体３０における第一の外辺８１及び第二の外辺８２に近い部位の五つの単位案内部３０ｆ、〜、３０ｊの大きさを、他の五つの単位案内部３０ａ、〜、３０ｅの大きさに対し所定割合に設定して、単位案内部３０ｆ、〜、３０ｊから吹出される調和空気副部の吹出し量を調整し、この調和空気副部の気流を第一の外辺８１及び第二の外辺８２寄りの吹出口本体１０外縁の額縁部１２に到達可能とする一方、気流案内体３０の他の単位案内部３０ａ、〜、３０ｅから吹出される調和空気主部に調和空気副部が誘引されて、最終的に調和空気主部と同じ方へ進行するような構成としているが、これに限らず、制御板２０の開口孔２１のうち、気流案内体３０の前記五つの単位案内部３０ｆ、〜、３０ｊにおける前記空気通路部分に連通する一の開口孔群の大きさと、気流案内体３０の他の単位案内部３０ａ、〜、３０ｅにおける前記空気通路部分に連通する他の開口孔群の大きさとを所定割合に設定して、単位案内部３０ｆ、〜、３０ｊから吹出される調和空気副部の吹出し量を他の単位案内部３０ａ、〜、３０ｅから吹出される調和空気主部より小さい所定量に調整し、この調和空気副部の気流を第一の外辺８１及び第二の外辺８２寄りの吹出口本体１０外縁の額縁部１２に到達可能とする一方、気流案内体３０の他の単位案内部３０ａ、〜、３０ｅから吹出される調和空気主部に調和空気副部が誘引されて、最終的に調和空気主部と同じ方へ進行するようにする構成とすることもできる。   Moreover, in the low temperature blower outlet apparatus which concerns on the said embodiment, the magnitude | size of the five unit guide parts 30f--30j of the site | part close | similar to the 1st outer side 81 and the 2nd outer side 82 in the airflow guide body 30 is set. , By setting a predetermined ratio with respect to the size of the other five unit guide parts 30a, ..., 30e, and adjusting the blowout amount of the conditioned air sub-parts blown from the unit guide parts 30f, ..., 30j. While allowing the air flow in the air sub-portion to reach the frame portion 12 on the outer edge of the outlet body 10 near the first outer edge 81 and the second outer edge 82, the other unit guide portions 30a of the air flow guide body 30 are: 30e, the conditioned air sub-portion is attracted to the conditioned air main portion blown out from 30e, and finally proceeds in the same direction as the conditioned air main portion. Of the holes 21, the five unit guide portions of the airflow guide body 30. The size of one opening hole group communicating with the air passage portion at 0f,..., 30j and the other opening hole group communicating with the air passage portion at the other unit guide portions 30a,. The amount of the conditioned air sub-portion blown from the unit guide portions 30f,..., 30j is set from the conditioned air main portion blown from the other unit guide portions 30a,. The air flow guide body 30 is adjusted to a small predetermined amount so that the airflow of the conditioned air sub-portion can reach the frame portion 12 of the outer edge of the outlet body 10 near the first outer side 81 and the second outer side 82. The conditioned air sub-part is attracted to the conditioned air main part blown out from the other unit guide parts 30a to 30e, so that the conditioned air main part is finally advanced in the same direction as the conditioned air main part. it can.

この場合も、前記実施形態と同様、モジュール８０の隅部８５近傍に偏って配設された吹出口装置から室内空間に対する空気調和を均一に実行できる状態を確保しつつ、吹出口本体１０外縁の額縁部１２をはじめとする吹出口本体１０の表面や化粧グリル４０が、調和空気の気流により室内空間の空気から隔離されることとなり、調和空気の吹出しに伴い吹出口付近へ誘引される二次空気と、調和空気で冷やされた吹出口装置表面各部との接触を阻止でき、吹出口装置表面各部における結露の発生やこれによる表面の汚染を防ぐことができることとなる。   In this case as well, as in the above-described embodiment, the air outlet body 10 is provided with a state in which air conditioning for the indoor space can be performed uniformly from the air outlet device disposed in the vicinity of the corner 85 of the module 80, and the outer edge of the air outlet body 10. The surface of the air outlet main body 10 including the frame portion 12 and the decorative grill 40 are isolated from the air in the indoor space by the air current of the conditioned air, and the secondary attracted to the vicinity of the air outlet as the conditioned air is blown out. Contact between the air and each part of the surface of the air outlet apparatus cooled by conditioned air can be prevented, and the occurrence of condensation on each part of the surface of the air outlet apparatus and the contamination of the surface due to this can be prevented.
