空気調和設備において、ダクトを通じて送られる空気調和用の空気を室内空間 に吹出す吹出口装置のうち、システム天井用として使用される吹出口装置として 、従来、図6に示すものがあった。この図6は従来の吹出口装置の概略構成断面 図である。 2. Description of the Related Art In an air conditioner, among air outlet devices for blowing air for air conditioning sent through a duct into a room, there is a conventional air outlet device used for a system ceiling as shown in FIG. FIG. 6 is a schematic sectional view of the configuration of a conventional outlet device.
【0003】 前記図6において従来の吹出口装置100は、天井50内に配設され、ダクト 51と接続されて空気調和用の空気を供給される略筒状のネック部101a及び 、室内吹出側に約30°の傾斜角度で拡開状となる矩形の外コーン部101bが 形成されてなる開口枠体101と、この開口枠体101の開口領域内側の所定位 置に気流案内部として配設され、室内吹出側に拡開状に形成されると共に、上側 表面において略L字状断面の気流偏向板102aが各吹出方向ごとに四箇所固定 されてなる矩形の多層コーンである中コーン102と、前記開口枠体101内部 の中コーン102上流に配設され、気流通路の中央で気流を遮る面積を調整自在 に形成され、気流が通過する通路外周部分の開口面積を変化させるサークルシャ ッター103とを備える構成である。Referring to FIG. 6, a conventional outlet device 100 is disposed in a ceiling 50, is connected to a duct 51, is supplied with air for air conditioning, and has a substantially cylindrical neck portion 101a; An opening frame body 101 formed with a rectangular outer cone portion 101b that expands at an inclination angle of about 30 °, and an airflow guide portion is provided at a predetermined position inside the opening area of the opening frame body 101. The middle cone 102, which is a rectangular multilayer cone formed with an air flow deflecting plate 102a having a substantially L-shaped cross section on the upper surface and fixed at four locations in each of the blowing directions while being formed in an expanded shape on the indoor blowing side. A circle shutter that is disposed upstream of the middle cone 102 inside the opening frame 101 and that is formed so as to have an adjustable airflow blocking area at the center of the airflow passage, and that changes the opening area of the outer periphery of the passage through which the airflow passes. A configuration and a over 103.
【0004】 上記した従来の吹出口装置100では、ダクト51から送られた調和空気が開 口枠体101内を流れ、サークルシャッター103により気体通路の外周側に導 かれて外コーン部101bと中コーン102との間に達し、中コーン102に沿 った気流が気流偏向板102aで偏向されて脇に流れ、中コーン102の各コー ナー部分から斜めに傾いた向きへ広がりをもって室内に吹出す。In the above-described conventional outlet device 100, the conditioned air sent from the duct 51 flows through the opening frame 101, is guided to the outer peripheral side of the gas passage by the circle shutter 103, and communicates with the outer cone portion 101 b. The air flow along the middle cone 102 is deflected by the airflow deflecting plate 102a and flows aside. .

従来の吹出口装置は以上のように構成されていたことから、冷房及び暖房にか かわらず吹出角度が斜め下方向に固定されて一定の斜め気流となるため、他の吹 出パターンへ変更ができず汎用性に乏しいと共に、冷房及び暖房に各々最適な吹 出パターンへ変更して気流を適切な吹出方向に吹出す場合に比べて気流の水平又 は垂直方向への到達距離が小さくなり、空気調和の対象となる室内へ均一に冷房 又は暖房ができにくいという課題を有していた。 Since the conventional outlet device was configured as described above, the outlet angle was fixed diagonally downward regardless of cooling and heating, resulting in a constant oblique airflow. In addition to the lack of general versatility, the airflow in the horizontal or vertical direction is shorter than in the case where the airflow is changed to the optimum airflow pattern for cooling and heating and the airflow is blown in the appropriate airflow direction. There was a problem that it was difficult to uniformly cool or heat the room to be air-conditioned.
【0006】 また、開口枠体101の外コーン部101bは、他の天井用吹出口と共用され る部品であり、水平吹出用の吹出口に用いられる場合において天井に対し略平行 な水平方向に調和空気をスムーズに吹出させるため一般に拡開角度を浅い角度の 約30°に設定されることが多く、これがそのまま用いられることから、中コー ン102との間隔の狭い部分が生じ、ここで気流の速度が速くなり騒音が発生し てしまうという課題を有した。[0006] The outer cone portion 101b of the opening frame body 101 is a part shared with other ceiling outlets, and is used in a horizontal direction substantially parallel to the ceiling when used for a horizontal outlet. In general, the divergence angle is often set to a shallow angle of about 30 ° in order to blow out the conditioned air smoothly, and since this is used as it is, a portion with a small gap with the middle cone 102 occurs, and the airflow is reduced. However, there was a problem that the speed was increased and noise was generated.
【0007】 本考案は前記課題を解消するためになされたもので、気流案内部の位置や気流 偏向板の角度を容易に調整でき、吹出パターンを変えて調和空気の温度に応じた 最適な空気調和性能が得られ、且つ騒音発生も少ない吹出口装置を提供すること を目的とする。[0007] The present invention has been made to solve the above-mentioned problems, and can easily adjust the position of the airflow guide portion and the angle of the airflow deflector, and change the blowing pattern to optimize the optimal air according to the temperature of the conditioned air. It is an object of the present invention to provide an air outlet device that can achieve harmonic performance and generate less noise.

本考案に係る吹出口装置は、空気調和用の気体が供給され、当該気体を空気調 和の対象となる空間へ吹出す開口領域を有し、当該開口周囲に室内吹出側へ向け て拡開状となる外コーン部が形成され、当該外コーン部下端に開口面に対し略垂 直に起立する縁部が形成されてなる開口枠体と、前記開口枠体の開口領域内にお いて下端位置が前記縁部の下端に略一致する高さ位置及び、当該位置から縁部高 さだけ上昇した高さ位置の二通りに位置調整可能に配設され、前記外コーン部内 側面に対向する拡開形状の側面を有する羽根体で形成され、当該羽根体及び開口 枠体の間で気流吹出方向を所定の二通りの向きに案内する気流案内部と、前記気 流案内部の気流との接触部分に配設され、所定の折曲線を挟んで一側が気流案内 部の表面に沿って固定されると共に、他側が一側に対して角度調整自在に折曲さ れる略板状体の気流偏向板と、前記開口枠体の開口領域内における前記気流案内 部の上流側に配設され、気流通路の中央部分で気流を遮って気流通路外周寄りに 気流を偏流させる偏流板とを備えるものである。このように本考案によれば、気 流案内部の開口枠体に対する配設位置及び、気流偏向板の他側の折曲角度をそれ ぞれ調整することにより、気流の吹出方向を変えて多様な吹出パターンが得られ 、空気調和能力を高められると共に、吹出方向の調整も容易で複雑な操作が要ら ず、取扱性に優れることとなる。 The outlet device according to the present invention has an opening area to which air conditioning gas is supplied and blows the gas into a space to be air-conditioned, and expands around the opening toward the indoor blowing side. An opening frame body having an outer cone portion formed in a shape thereof, and an edge portion standing substantially perpendicular to an opening surface formed at a lower end of the outer cone portion; and a lower end in an opening region of the opening frame body. A position is provided so as to be adjustable in two positions, a height position where the position substantially coincides with the lower end of the edge portion, and a height position which is raised from the position by the edge height, and an expansion portion facing the inner side surface of the outer cone portion. An airflow guide formed of a blade body having an open side surface, for guiding the airflow blowing direction between the blade body and the opening frame body in two predetermined directions, and contact with the airflow of the airflow guide section. Part, with one side along the surface of the airflow guide part across a predetermined folding curve A substantially plate-shaped airflow deflector plate that is fixed and the other side is bent so as to be adjustable in angle with respect to one side, and is disposed on the upstream side of the airflow guide in the opening area of the opening frame. And a deflector plate that blocks the airflow at the center of the airflow passage and deviates the airflow toward the outer periphery of the airflow passage. As described above, according to the present invention, the position of the airflow guide portion with respect to the opening frame and the bending angle of the other side of the airflow deflector are adjusted to change the airflow blowout direction. As a result, it is possible to improve the air-conditioning ability, to easily adjust the blowing direction, and to perform complicated operations without requiring complicated operations.
【0009】 また、本考案に係る吹出口装置は必要に応じて、前記気流偏向板が、気流の温 度に応じて前記折曲線を挟んだ他側が起立又は倒伏する形状記憶合金製の略板状 体として形成されるものである。このように本考案によれば、気流偏向板が気流 の温度変化に応じて自動的に起立又は倒伏動作を行って吹出パターンを変化させ られることにより、作業者による吹出方向の調整がほとんど不要となり、作業の 大幅な省力化が図れる。In addition, the air outlet device according to the present invention may be configured such that the airflow deflector plate is, as required, a substantially plate made of a shape memory alloy in which the other side of the bent curve stands up or down depending on the temperature of the airflow. It is formed as a body. As described above, according to the present invention, the airflow deflecting plate automatically rises or falls down in response to a change in the temperature of the airflow to change the blowout pattern, thereby making it almost unnecessary for the operator to adjust the blowout direction. In addition, significant labor savings can be achieved.
【0010】 また、本考案に係る吹出口装置は必要に応じて、前記気流偏向板の折曲線を挟 んだ一側及び他側にそれぞれ端部を固着させて配設され、気流の温度に応じて変 形して前記気流偏向板の他側を起立又は倒伏させる形状記憶合金製略板状体の補 助板を備えるものである。このように本考案によれば、補助板で気流偏向板を動 かして自動的に気流の温度に応じた吹出パターンに変化させられることにより、 作業者による吹出方向の調整がほとんど不要となり、作業の大幅な省力化が図れ ると共に、形状記憶合金の使用を抑えてより低コスト化が図れる。In addition, the air outlet device according to the present invention is disposed, if necessary, with its ends fixed to one side and the other side of the airflow deflector sandwiching the fold curve, so that the airflow temperature can be controlled. An auxiliary plate of a substantially plate-shaped body made of a shape memory alloy, which is deformed accordingly to raise or lower the other side of the airflow deflection plate. As described above, according to the present invention, the airflow deflecting plate is moved by the auxiliary plate to automatically change the airflow pattern according to the temperature of the airflow. The work can be greatly reduced in labor, and the cost can be reduced by suppressing the use of the shape memory alloy.
【0011】 また、本考案に係る吹出口装置は必要に応じて、前記開口枠体の外コーン部が 、拡開する傾斜角度を開口面に対して35°ないし45°の範囲で形成されるも のである。このように本考案によれば、外コーン部の角度を適正にすることによ り、外コーン部と気流案内部の間の間隔を広げて気流の速度を抑え、風切り音等 の騒音を大きく低減できると共に、気流の案内性能が向上し、確実にコーナー吹 出が行える。In addition, in the blow-out device according to the present invention, the outer cone portion of the opening frame is formed such that the inclination angle at which the opening expands is in the range of 35 ° to 45 ° with respect to the opening surface. It is a thing. As described above, according to the present invention, by adjusting the angle of the outer cone portion, the interval between the outer cone portion and the airflow guide portion is widened to suppress the speed of the airflow, thereby increasing noise such as wind noise. In addition to being able to reduce airflow, the airflow guidance performance is improved, and corner blowing can be performed reliably.
【0012】 また、本考案に係る吹出口装置は必要に応じて、前記気流偏向板が、折曲され る他側の角部分に丸面取りを施されるものである。このように本考案によれば、 気流偏向板に丸面取りを施すことにより、気流偏向板における風切り音の発生を 防ぎ、開口部からの騒音を減少させられる。Further, in the air outlet device according to the present invention, if necessary, the airflow deflector plate is rounded at a corner portion on the other side to be bent. As described above, according to the present invention, by performing round chamfering on the airflow deflecting plate, generation of wind noise at the airflow deflecting plate can be prevented, and noise from the opening can be reduced.
【0013】 また、本考案に係る吹出口装置は必要に応じて、前記気流偏向板の折曲部位に 、折曲線に合わせて肉抜きする折曲孔部が穿設されるものである。このように本 考案によれば、気流偏向板の折曲部に肉抜きがなされていることにより、折曲げ の際に強い力が不要になると共に、誤った箇所で折れ曲ることなく正しい位置で 確実に折曲加工でき、作業性、製作性の向上が図れることとなる。[0013] In addition, the outlet device according to the present invention is provided with a bent hole portion, which is formed as necessary, in a bent portion of the airflow deflector plate in accordance with a bent curve. As described above, according to the present invention, since the bent portion of the airflow deflector is cut off, a strong force is not required at the time of bending, and a correct position without bending at an erroneous portion is obtained. Therefore, the bending process can be performed reliably, and workability and manufacturability can be improved.

【0015】 前記各図に示すように、本実施の形態に係る吹出口装置1は、円筒形状のネッ ク部2a及び室内吹出側に拡開状に形成される矩形の外コーン部2bを有する開 口枠体2と、この開口枠体2の開口領域内側に配設され、室内吹出側に向けて矩 形拡開状に形成される気流案内部としての中コーン3と、この中コーン3の外側 面にそれぞれ配設される気流偏向板4と、前記中コーン3と一体に配設される棒 状の支持部材5と、この支持部材5の先端に回動自在に装着されるキャップ6と 、開口枠体2内側面に装着され、前記キャップ6を嵌合させることで前記中コー ン3を所定位置に保持する保持具7と、前記開口枠体2内部の中コーン3上流に 偏流板として配設され、気流通路の中央で径を拡大・縮小させて外周側の開口面 積を調整する公知のサークルシャッター8とを備える構成である。As shown in the drawings, the outlet device 1 according to the present embodiment has a cylindrical net portion 2a and a rectangular outer cone portion 2b formed in an expanded shape on the indoor outlet side. An opening frame 2; a middle cone 3 as an airflow guide disposed inside the opening area of the opening frame 2 and formed in a rectangular shape expanding toward the indoor blowing side; An airflow deflector plate 4 disposed on the outer surface of each of the members, a rod-shaped support member 5 disposed integrally with the middle cone 3, and a cap 6 rotatably mounted on the tip of the support member 5. And a holder 7 mounted on the inner side surface of the opening frame 2 and holding the middle cone 3 at a predetermined position by fitting the cap 6, and a drift upstream of the middle cone 3 inside the opening frame 2. It is arranged as a plate, and the diameter is enlarged or reduced at the center of the airflow passage, and the opening area on the outer peripheral side is And a well-known circle shutter 8 for adjusting the distance.
【0016】 前記開口枠体2は、拡開形状の外コーン部2bの傾斜角度を開口面に対し37 °として従来より傾斜させて形成し、この外コーン部2bの下縁に開口面に対し て垂直に起立した縁部2cを形成されると共に、内側壁の四箇所に保持具7をそ れぞれ配設されてなり、ネック部2aを天井50内でダクト51に接続して調和 空気を取込み、室内側開口部分から室内に吹出させる構成である。The opening frame 2 is formed by inclining the outer cone portion 2b of the expanded shape at an angle of 37 ° with respect to the opening surface and inclining the outer cone portion 2b with respect to the opening surface. A vertically extending edge 2c is formed, and holders 7 are disposed at four places on the inner wall, respectively, and the neck 2a is connected to the duct 51 in the ceiling 50 to form a conditioned air. This is configured to take in air and blow it out of the room through the indoor opening.
【0017】 前記気流偏向板4は、所定の大きさの鋼板に折曲線を設定し、これを挟んで一 側が中コーン3の外側表面に沿って固定されると共に、他側が一側に対して角度 調整自在に折曲され、傾斜部分を形成されてなる構成である。この気流偏向板4 の折曲部分には、折曲しやすいように折曲線に合わせて肉抜きの折曲孔部4aが 打抜きにより形成される。また、気流偏向板4の角部分には、丸面取りが施され 、風切り音等の騒音の発生を防いでいる。The airflow deflecting plate 4 sets a bent curve on a steel plate of a predetermined size, and one side of the bent surface is fixed along the outer surface of the middle cone 3, and the other side is fixed to the one side. The angle is adjusted so as to be adjustable, and the inclined portion is formed. In the bent portion of the airflow deflecting plate 4, a bent hole portion 4a is formed by punching in accordance with a bending curve so as to be easily bent. Further, the corners of the airflow deflector 4 are rounded to prevent noise such as wind noise.
【0018】 前記支持部材5は、略棒状体に形成され、中コーン3の上部に十字状に配置さ れて先端が中コーン3外側に突出した状態で中コーン3と一体化されて配設され る構成である。The support member 5 is formed in a substantially rod shape, is arranged in a cross shape above the middle cone 3, and is disposed integrally with the middle cone 3 with its tip protruding outside the middle cone 3. This is the configuration that is used.
【0019】 前記キャップ6は、前記支持部材5の先端に回動自在に配設され、二つの同一 形状の被嵌合部6a、6bを回動の中心位置からの距離の差が開口枠体2の縁部 2c高さと同じ長さになるように回動の中心から不等距離でそれぞれ形成され、 上下の被嵌合部6a、6bの中間の側面にくびれ部6cを形成して上下左右対称 の繭形断面形状とされてなる構成である。The cap 6 is rotatably disposed at the tip of the support member 5, and the difference in distance between two fitted portions 6 a and 6 b having the same shape from the center of rotation is an opening frame. 2 are formed at unequal distances from the center of rotation so as to have the same length as the height 2c of the edge 2c. It has a symmetrical cocoon-shaped cross section.
【0020】 前記保持具7は、前記キャップ6の被嵌合部6a、6bを受けて下から支え、 開いた上端がキャップ6のくびれ部6cに弾性力をもって嵌脱自在に嵌まり込ん でキャップ6を両側から挟み込む形状に形成される構成である。この保持具7は 、キャップ6の回動中心との間隔が小さい方の被嵌合部6aを保持具7に嵌合さ せた時は中コーン3下端が開口枠体2の下端に略同一の高さ位置となり、また、 キャップ6回動中心との間隔が大きい方の被嵌合部6bを保持具7に嵌合させた 時は前記位置から縁部2cの高さだけ上昇した高さ位置となるよう、開口枠体2 の内側壁の所定位置に配設される。The holder 7 receives the fitted portions 6 a and 6 b of the cap 6 and supports it from below, and the open upper end is removably fitted into the constricted portion 6 c of the cap 6 with elastic force. 6 is formed in a shape sandwiching both sides. The lower end of the middle cone 3 is substantially the same as the lower end of the opening frame 2 when the fitted portion 6 a having a smaller distance from the center of rotation of the cap 6 is fitted to the holder 7. When the fitted portion 6b having a larger distance from the center of rotation of the cap 6 is fitted to the holder 7, the height raised from the above-described position by the height of the edge 2c. It is disposed at a predetermined position on the inner side wall of the opening frame 2 so as to be located at the position.
【0021】 次に、前記構成に基づく吹出口装置における吹出パターン調整動作及び吹出状 態について説明する。 まず、保持具7に係合されるキャップ6の向きを調整し、水平吹出及び斜め吹 出の場合は、被嵌合部6aを下側に位置させ、開口枠体2と中コーン3の両下端 がほぼ揃った状態とし、垂直吹出の場合は、被嵌合部6bを下側に位置させ、中 コーン3下端が開口枠体2の縁部2cの高さ分だけ上がった状態となるようにす る。Next, a blow-out pattern adjusting operation and a blow-out state in the blow-out device based on the above configuration will be described. First, the direction of the cap 6 engaged with the holder 7 is adjusted, and in the case of horizontal blowing and oblique blowing, the fitted portion 6a is positioned on the lower side, and both the opening frame 2 and the middle cone 3 are positioned. The lower ends are almost aligned, and in the case of vertical blowing, the fitted portion 6b is positioned on the lower side, and the lower end of the middle cone 3 is raised by the height of the edge 2c of the opening frame 2. To
【0022】 調和空気をダクト51から開口枠体2のネック部2aに送込むと、開口枠体2 内のサークルシャッター8で気流が気体通路の外周寄りに導かれ、外コーン部2 bと中コーン3との間に達する。外コーン部2bの傾斜を大きくしていることに より、外コーン部2bと中コーン3との間の気流通路が広がり、気流速度が速く ならず騒音の発生が減少する。When the conditioned air is sent from the duct 51 to the neck 2 a of the opening frame 2, the airflow is guided toward the outer periphery of the gas passage by the circle shutter 8 in the opening frame 2, and the outer cone 2 b and the middle portion are formed. It reaches between cone 3. By increasing the inclination of the outer cone portion 2b, the airflow path between the outer cone portion 2b and the middle cone 3 is widened, so that the airflow speed is not increased and noise generation is reduced.
【0023】 冷房使用時等の水平吹出では、調和空気が中コーン3に沿って次第に横向に流 れ、気流偏向板4を折曲げていないのでそのまま水平に室内に吹出す。気流は室 内の空気を誘引し、誘引空気流が生じる。特に冷房の場合、室内の空気より重い 冷気を横向に吹出して天井50から居住域に達するまでに十分室内に拡散させら れることに加え、冷気が比較的暖かい天井50付近の空気を誘引して、これらと 混合するため、室内空気の冷却効果を高められる。In the case of horizontal blowing during cooling or the like, the conditioned air gradually flows sideways along the middle cone 3 and blows out horizontally into the room as it is because the airflow deflector 4 is not bent. The airflow attracts the air in the room, and an induced airflow is generated. In particular, in the case of cooling, in addition to blowing out cold air that is heavier than indoor air laterally and sufficiently diffusing it from the ceiling 50 to reach the living area, the cool air attracts air near the relatively warm ceiling 50. As a result, the cooling effect of indoor air can be enhanced.
【0024】 一方、暖房使用時等の垂直吹出では、調和空気は中コーン3に沿って次第に横 向に流れるが、中コーン3を離れた横向きの気流が外コーン部2b下側の縁部2 cに当って流れの方向を変えることによって、下向きに室内に吹出す。室内を下 方に向う気流は室内の空気を誘引し、誘引空気流が生じる。特に暖房の場合、室 内の空気より軽い暖気を天井50から下向きに吹出して確実に居住域まで到達さ せることができる上、暖気はより温度の低い室内の空気を誘引し、これらと混合 するため、室内空気への熱の伝導が促進され、室内空気の温度を上げる効果が大 きい。On the other hand, in a vertical blowout during heating or the like, the conditioned air gradually flows sideways along the middle cone 3, but a horizontal airflow that has left the middle cone 3 causes the edge 2 below the outer cone 2 b to be lower. It blows down into the room by changing the direction of the flow on c. Downward airflow in the room induces air in the room, creating an induced airflow. In particular, in the case of heating, warm air, which is lighter than the room air, can be blown downward from the ceiling 50 to reliably reach the living area, and the warm air attracts and mixes the cooler room air. Therefore, the conduction of heat to the indoor air is promoted, and the effect of raising the temperature of the indoor air is great.
【0025】 また、斜め吹出では、中コーン3に配設された気流偏向板4の傾斜角度を調整 して、吹出す向きを変化させる。気流偏向板4の折曲角度を約90°として起立 させた状態とすると、気流が気流偏向板4に遮られて中コーン3上で左右の脇に 流れ、気流偏向板4のないコーナー部から吹出すことにより、図4中に実線で示 すように天井面から斜め下方に傾いた向きへ広がりをもって室内に吹出せる。気 流偏向板4の折曲角度を小さくすると、そのまま中コーン3に沿って吹出す気流 も生じ、偏向されてコーナー部から吹出す気流と合わさって、吹出口周囲の各方 向にやや斜め下向きに吹出すこととなる。気流偏向板4を全く折曲げない状態で は、気流の吹出は、全て中コーン3に沿って水平吹出の場合と同様に横向きに吹 出すこととなる。特に冷房の場合、気流偏向板4を起立させて冷気を天井50か ら斜め下向きに吹出すことで、吹出気流の下方への到達距離が短くなり、居住域 におけるドラフトを感じにくくなる。その一方、気流は水平方向に拡散し且つ室 内空気を誘引してこれらと混合するため、室内における冷気の到達範囲は逆に拡 大し、デッドゾーンをほとんど発生させずに効率よく冷房が行えることとなる。 また、斜め下方への吹出のために天井付近への室内空気の誘引量が少なく、汚れ た室内空気による天井面の汚染が発生しにくい。さらに、図4に示すようにシス テム天井として吸込口を近傍に配設されても、コーナー部から吹出すため、天井 吸込によるショートサーキット量が少ない。In the case of oblique blowing, the direction of air blowing is changed by adjusting the inclination angle of the airflow deflector 4 provided on the middle cone 3. When the airflow deflector 4 is set up at a bending angle of about 90 °, the airflow is interrupted by the airflow deflector 4 and flows to the left and right sides on the middle cone 3. By blowing out, as shown by the solid line in FIG. 4, the air can be blown into the room with a spread in a direction inclined obliquely downward from the ceiling surface. When the bending angle of the airflow deflector 4 is reduced, an airflow blown out along the middle cone 3 is generated as it is, and the airflow is deflected and combined with the airflow blown out from the corner, so that the airflow is slightly obliquely downward in each direction around the outlet. Will be blown out. In a state where the airflow deflector 4 is not bent at all, all the airflow blows out along the middle cone 3 in the horizontal direction as in the case of the horizontal blowout. In particular, in the case of cooling, by raising the airflow deflector 4 and blowing the cool air obliquely downward from the ceiling 50, the reaching distance of the blown airflow below becomes short, and the draft in the living area becomes hard to feel. On the other hand, the air current diffuses in the horizontal direction and attracts and mixes the air in the room, so that the reach of the cool air in the room expands conversely, and cooling can be performed efficiently with almost no dead zone. It will be. In addition, since the air is blown obliquely downward, the amount of indoor air attracted to the vicinity of the ceiling is small, and the ceiling surface is not easily polluted by dirty indoor air. Furthermore, even if the suction port is arranged near the system ceiling as shown in FIG. 4, since the air is blown out from the corner, the short circuit amount due to the ceiling suction is small.
【0026】 このように、本実施の形態に係る吹出口装置では、中コーン3全体の位置調整 で水平吹出と垂直吹出を切替えると共に、気流偏向板4の傾斜角度を調整するこ とで気流のコーナー部からの吹出量を調節することができ、斜め吹出の度合を自 由に変えて、設置箇所や空気調和の状況に応じた最適な吹出パターンが容易に得 られ、汎用性が高い。As described above, in the air outlet device according to the present embodiment, the horizontal flow and the vertical flow are switched by adjusting the position of the entire middle cone 3, and the air flow is controlled by adjusting the inclination angle of the air flow deflector 4. The amount of air blown from the corner can be adjusted, the degree of oblique air blow can be changed freely, and the optimum blow pattern can be easily obtained according to the installation location and the condition of air conditioning.
【0027】 なお、前記実施の形態に係る吹出口装置においては、開口枠体2の開口領域内 に気流案内部として中コーン3を備える構成としているが、多層コーン型の他に パン型の吹出口として、図5に示すように、気流案内部として中パン9を配設し 、この中パン9の上面に気流偏向板4をそれぞれ配設する構成とすることもでき る。In the outlet device according to the above-described embodiment, the middle cone 3 is provided as an airflow guide in the opening area of the opening frame 2. As shown in FIG. 5, a middle pan 9 may be provided as an airflow guide as an outlet, and the airflow deflector 4 may be provided on the upper surface of the middle pan 9.
【0028】 また、前記実施の形態に係る吹出口装置において、気流偏向板4は鋼板製とす る構成としているが、この気流偏向板4が気流の温度に応じて変形し、気流の温 度が約17℃以下の場合には全く折曲らずに中コーン3表面に沿うと共に、気流 の温度が約25℃以上の場合には約90°の折曲角度で起立する形状記憶合金製 薄板とされてなる構成とすることもでき、気流の温度変化に応じて自動的に吹出 方向が切替えられ、切替え作業が不要となり、省力化が図れる。この他、気流偏 向板4の折曲線を挟んだ一側及び他側に形状記憶合金製の補助板の端部を固着さ せ、気流の温度に応じた補助板の変形で気流偏向板4の他側を起立又は倒伏させ る構成とすることもでき、前者同様気流の温度変化に応じて自動的に吹出方向が 切替えられ、省力化が図れると共に、形状記憶合金の使用量を少なくでき、より 低コスト化できる。In the outlet device according to the embodiment, the airflow deflector 4 is made of a steel plate. However, the airflow deflector 4 is deformed in accordance with the temperature of the airflow, and the temperature of the airflow is reduced. When the temperature is about 17 ° C. or less, the sheet does not bend at all and follows the surface of the middle cone 3, and when the temperature of the air stream is about 25 ° C. or more, it stands at a bending angle of about 90 °. The blowing direction is automatically switched according to a change in the temperature of the airflow, so that the switching operation is not required and labor can be saved. In addition, an end of an auxiliary plate made of a shape memory alloy is fixed to one side and the other side of the airflow deflection plate 4 on both sides of the bent curve, and the airflow deflection plate 4 is deformed according to the temperature of the airflow. It is also possible to make the other side stand up or fall down, the blowing direction is automatically switched according to the temperature change of the airflow as in the former case, saving power and reducing the amount of shape memory alloy used. Lower costs can be achieved.
【0029】 また、前記実施の形態に係る吹出口装置においては、水平、垂直及び斜めの三 通りの吹出を切替える構成としているが、これらに加えて、垂直吹出と同様キャ ップ6の被嵌合部6bを下側に位置させ、中コーン3下端が開口枠体2の縁部2 cの高さ分だけ上がった状態から、更に気流偏向板4を中コーン3に対し起立さ せた状態で行われる気流吹出を利用する構成とすることもでき、この吹出では気 流が気流偏向板4に遮られて中コーン3上で左右の脇に流れ、気流偏向板4のな いコーナー部から縁部2cに沿って吹出すことにより、図4中に破線で示すよう に室内に斜め下方に広がりをもって下向きに吹出す気流となり、特に暖房の場合 、下向きの気流が広がりを持って居住域に達することで、大風量でもドラフトを 感じにくくすることができる。In the outlet device according to the above-described embodiment, the horizontal, vertical, and oblique air outlets are switched. However, in addition to the above, the cap 6 can be fitted similarly to the vertical air outlet. The joining portion 6b is located on the lower side, and the airflow deflector 4 is further raised with respect to the middle cone 3 from the state where the lower end of the middle cone 3 is raised by the height of the edge 2c of the opening frame 2. In this blowout, the airflow is blocked by the airflow deflecting plate 4 and flows to the left and right on the middle cone 3, and from the corner where the airflow deflecting plate 4 is not provided. By blowing out along the edge 2c, as shown by the broken line in FIG. 4, the airflow spreads obliquely downward into the room and blows downward. Especially in the case of heating, the downward airflow spreads out into the living area. Achieving drafts even at high airflows It can be difficult to repel.

This has the effect that bending can be performed reliably and workability and manufacturability can be improved.
