Description

本発明は、天井内に本体ユニットが埋設された天井埋込型空気調和機に関し、さらに詳しく言えば風向板を軸支する軸受部の構造に関するものである。   The present invention relates to a ceiling-embedded air conditioner in which a main unit is embedded in a ceiling, and more particularly to a structure of a bearing portion that pivotally supports a wind direction plate.

天井埋込型空気調和機は、内部に熱交換器および送風ファン(ターボファン)を含む箱型の本体ユニットを天井内に埋設し、本体ユニットの底面に取り付けられた化粧パネルの吸込グリルから吸い込んだ空気を熱交換器で冷媒と熱交換して、吹出口から風向板で風向を調節して室内に送出する空気調和機で、オフィスや店舗等の比較的広い室内に用いられている。   In a ceiling-embedded air conditioner, a box-shaped main unit including a heat exchanger and a blower fan (turbo fan) is embedded in the ceiling, and sucked from a suction grill on a decorative panel attached to the bottom of the main unit. It is an air conditioner that exchanges heat with refrigerant in a heat exchanger, adjusts the air direction from the air outlet with a wind direction plate, and sends it out indoors. It is used in relatively large rooms such as offices and stores.

従来例の天井埋込型空気調和機は、吹出口が開口された化粧パネル(空気調和機本体)の吹出口側の壁面に設けた支持穴に風向板の可動軸を取り付けて風向板を支持し、風向板を上下に回動することで、一方向に空気を吹き出していた。(特許文献1参照)   The ceiling-embedded air conditioner of the conventional example supports the wind direction plate by attaching the movable shaft of the wind direction plate to the support hole provided in the wall on the blower outlet side of the decorative panel (air conditioner body) with the air outlet opened. Then, air was blown out in one direction by rotating the wind direction plate up and down. (See Patent Document 1)

特開2003−240258号公報JP 2003-240258 A

従来例では吹出口の開口に沿って一方向に空気が吹き出されるが、化粧パネルの角部方向へ向かっては吹き出されないことで空調室内の室温が不均一となっていた。   In the conventional example, air is blown out in one direction along the opening of the outlet, but the room temperature in the air-conditioned room is not uniform because it is not blown out toward the corner portion of the decorative panel.

また、支持穴を設けた化粧パネルの壁面では、空気の流れる吹出口側の壁面とその裏面に当たる本体側の壁面で温度差があり結露が発生するため、吹出口側の壁面に断熱部材を設ける必要があった。   In addition, on the wall surface of the decorative panel provided with support holes, since there is a temperature difference between the wall surface on the air outlet side through which air flows and the wall surface on the main body side that contacts the back surface, condensation occurs. There was a need.

本発明は以上述べた問題点を解決し、全方位へ吹出空気を送風することが可能となり、かつ、風向板を軸支する壁面に温度差を発生させない天井埋込型空気調和機を提供することを目的とする。   The present invention solves the above-described problems, and provides a ceiling-embedded air conditioner that can blow the blown air in all directions and that does not generate a temperature difference on the wall surface that supports the wind direction plate. For the purpose.

上述した課題を解決するために本発明は、空調室の天井に埋設され内部に送風ファンと同送風ファンを囲む熱交換器を備えた箱型の本体ユニットと、同本体ユニットの下面に取り付けて前記天井を覆う四角形の化粧パネルを有する天井埋込型空気調和機において、
前記化粧パネルは、枠状の外枠部と、同外枠部より内側に配置される枠状の内枠部と、前記外枠部と前記内枠部を角部で繋ぐ接続部で形成され、前記外枠部と前記内枠部の間が吹出用通路となり、同吹出用通路内で隣り合う前記接続部の間開口が吹出口となり、前記化粧パネルの四角形の各辺に沿って前記吹出口の長辺よりも長い風向板で前記吹出用通路を覆い、前記風向板は、前記吹出口に対向する風向部と、前記風向部の端で前記吹出用通路に対向する補助風向部を有し、前記風向板が回動して前記風向板の前記内枠部側が前記吹出用通路内に移動した時に、前記風向板の前記補助風向部と前記接続部とで角隅吹出部を形成し、前記風向板は軸部を備え、前記接続部には板状の軸受用支柱が立設し、前記軸受用支柱は先端に前記軸部を軸支する軸孔を備えるとともに前記軸孔と前記接続部の間に通気孔を設けることを特徴とする。
In order to solve the above-described problems, the present invention includes a box-shaped main body unit that is embedded in a ceiling of an air-conditioning room and includes a blower fan and a heat exchanger that surrounds the blower fan, and is attached to a lower surface of the main body unit. In the ceiling-embedded air conditioner having a rectangular decorative panel covering the ceiling,
The decorative panel is formed by a frame-shaped outer frame portion, a frame-shaped inner frame portion disposed inside the outer frame portion, and a connection portion that connects the outer frame portion and the inner frame portion at corners. The space between the outer frame portion and the inner frame portion serves as a blowout passage, and an opening between the connecting portions adjacent in the blowout passage serves as a blowout port, along the square sides of the decorative panel. The blowout passage is covered with a wind direction plate that is longer than the long side of the blowout port, and the wind direction plate has a wind direction portion that faces the blowout port, and an auxiliary wind direction portion that faces the blowout passage at the end of the wind direction portion. And when the wind direction plate rotates and the inner frame portion side of the wind direction plate moves into the blowout passage, the auxiliary wind direction portion and the connection portion of the wind direction plate form a corner corner blowout portion. and, wherein the wind direction plate is provided with a shaft portion, the connecting uprights for the plate-shaped bearing is erected, the column forming the bearing of the shaft portion to the distal end Provided with a shaft hole for supporting and providing a vent between the connecting part and the shaft hole.

上記のように構成した本発明の天井埋込空気調和機は、化粧パネルに吹出口の長辺よりも長い風向板と吹出用通路を設けることで、全方位へ送風することが可能となる。また、化粧パネルの接続部には板状の軸受用支柱が立設し、軸受用支柱は先端に風向板の軸部を軸支する軸孔を備えるとともに軸孔と接続部の間に通気孔を設けることで軸受用支柱が通風の抵抗となることを軽減して多くの空気が吹き出される。さらに、軸受用支柱の両面に発生する結露防止することができ、軸受用支柱に断熱部材が不要となる。   The ceiling-embedded air conditioner of the present invention configured as described above can be blown in all directions by providing the decorative panel with a wind direction plate and a blowing passage longer than the long side of the outlet. In addition, a plate-like bearing support column is erected at the connection portion of the decorative panel, and the bearing support column has a shaft hole that supports the shaft portion of the wind direction plate at the tip, and a vent hole between the shaft hole and the connection portion. By providing the above, it is possible to reduce the bearing struts from becoming resistance to ventilation and to blow out a lot of air. Furthermore, it is possible to prevent dew condensation occurring on both surfaces of the bearing post, and a heat insulating member is not required for the bearing post.

以下、本発明を実施するための形態を、添付図面に基づいた実施例として詳細に説明するが、本発明はこれに限定されるものではない。   DESCRIPTION OF EMBODIMENTS Hereinafter, modes for carrying out the present invention will be described in detail as examples based on the accompanying drawings, but the present invention is not limited to these.

図1から図3に示す本発明による天井埋込型空気調和機1(以下、空気調和機1とする)は、空調室K内の天井Tに埋設される箱型の本体ユニット10と、同本体ユニットの底面101に取り付ける四角形の化粧パネル3とを備える。   A ceiling-embedded air conditioner 1 (hereinafter referred to as an air conditioner 1) according to the present invention shown in FIGS. 1 to 3 is the same as the box-type main unit 10 embedded in the ceiling T in the air-conditioning room K. A rectangular decorative panel 3 attached to the bottom surface 101 of the main unit.

本体ユニット10は、正方形の四辺を長辺とし、正方形の四つの角を面取りしてできた四辺を短辺とする略八角形となる板金で形成された天板13と、天板13の外周から下方に延在する側板11とで外郭が形成される。側板11は、天板13の短辺に沿って位置する側板11aの4箇所に外側に向かって折れ曲がった吊下部121と固定部122を備えた取付金具12が固着されている。本体ユニット10は、この吊下部121を図示しない天井裏壁面に埋め込まれた複数の吊りボルトにて吊り下げることで天井Tに設置される。   The main unit 10 includes a top plate 13 formed of a sheet metal having a substantially octagonal shape with four sides of a square as a long side and four sides of the square chamfered as a short side, and an outer periphery of the top plate 13. An outer shell is formed with the side plate 11 extending downward from the side plate. In the side plate 11, the mounting bracket 12 having a hanging portion 121 and a fixing portion 122 that are bent outward is fixed to four locations of the side plate 11 a located along the short side of the top plate 13. The main unit 10 is installed on the ceiling T by suspending the suspended portion 121 with a plurality of suspension bolts embedded in a ceiling wall surface (not shown).

尚、図2における本体ユニット10において、天板13方向を上面または上方、空調室K方向を下面または下方として以下説明する。各部品においても同様である。   In the main unit 10 in FIG. 2, the following description will be made with the top plate 13 direction as the upper surface or upper direction and the air-conditioned room K direction as the lower surface or lower direction. The same applies to each part.

本体ユニット10の天板13と側板11の内周面には図2に示すように断熱部材14が設けられる。また、天板13の中央内側にはネジによりファンモータ21が固定され、ファンモータ21から下方に伸びるシャフト22に送風ファン23のハブ23aが軸支される。送風ファン23はハブ23aとシュラウド23bと複数のブレード23cとからなる所謂ターボファンである。   A heat insulating member 14 is provided on the inner peripheral surface of the top plate 13 and the side plate 11 of the main unit 10 as shown in FIG. A fan motor 21 is fixed inside the top plate 13 by screws, and a hub 23a of the blower fan 23 is pivotally supported on a shaft 22 extending downward from the fan motor 21. The blower fan 23 is a so-called turbo fan including a hub 23a, a shroud 23b, and a plurality of blades 23c.

本体ユニット10の下部はドレンパン60で覆われる。ドレンパン60の中央部分は開口され吸込口16となる。吸込口16には吸込口16と送風ファン23とを繋ぐベルマウス24が配置される。また、ベルマウス24の吸込口16側には、吸込口16を通る空気Wの妨げにならないようにL字状に形成された電装品箱18が配置される。電装品箱18内には空気調和機1を制御する電装部品が収納される。   The lower part of the main unit 10 is covered with a drain pan 60. A central portion of the drain pan 60 is opened and serves as a suction port 16. A bell mouth 24 that connects the suction port 16 and the blower fan 23 is disposed in the suction port 16. Further, an electrical component box 18 formed in an L shape is arranged on the suction port 16 side of the bell mouth 24 so as not to interfere with the air W passing through the suction port 16. An electrical component for controlling the air conditioner 1 is accommodated in the electrical component box 18.

ファンモータ21により回転駆動される送風ファン23により、吸込口16から空調室内の空気Wが本体ユニット10内に吸い込まれる。本体ユニット10内に吸い込まれた空気Wは、ベルマウス24に沿って送風ファン23に案内され、送風ファン23の外方に向かって吹き出される。   The air W in the air-conditioned room is sucked into the main unit 10 from the suction port 16 by the blower fan 23 that is rotationally driven by the fan motor 21. The air W sucked into the main unit 10 is guided to the blower fan 23 along the bell mouth 24 and blown out toward the outside of the blower fan 23.

送風ファン23の周囲には、送風ファン23を囲み断熱部材14とドレンパン60とで上下を挟まれた熱交換器25が配設される。熱交換器25の下部を受けるドレンパン60は断熱部材61とドレンシート62でなる。熱交換器25と対向する面に樹脂製のドレンシート62が発泡樹脂の断熱部材61と一体に成形され熱交換器25で生成されるドレン水を受け止める。ドレン水は図示しないドレンポンプとドレンポンプに繋がったドレンパイプにより屋外へ排出される。   Around the blower fan 23, a heat exchanger 25 that surrounds the blower fan 23 and is sandwiched between the heat insulating member 14 and the drain pan 60 is disposed. A drain pan 60 that receives the lower part of the heat exchanger 25 is composed of a heat insulating member 61 and a drain sheet 62. A resin drain sheet 62 is formed integrally with the foamed heat insulating member 61 on the surface facing the heat exchanger 25 to receive drain water generated by the heat exchanger 25. The drain water is discharged outside by a drain pump (not shown) and a drain pipe connected to the drain pump.

熱交換器25は、図示しない冷房運転と暖房運転とが可能な可逆式の冷凍サイクル回路に接続されており、送風ファン23から導かれた空気Wを冷房運転時には蒸発器として機能して冷却し、暖房運転時には凝縮器として機能して加熱する。   The heat exchanger 25 is connected to a reversible refrigeration cycle circuit capable of a cooling operation and a heating operation (not shown), and cools the air W guided from the blower fan 23 by functioning as an evaporator during the cooling operation. During heating operation, it functions as a condenser and heats.

熱交換器25と側板11の内周面の断熱部材14との間と、ドレンパン60に設けられた本体ユニット10の四辺それぞれに沿った4つの本体吹出口15は、送風ファン23から吹き出された空気Wを後述する化粧パネル3の吹出口31へ案内する送風路17となる。熱交換器25で冷媒と熱交換された空気Wは送風路17と本体吹出口15を通り後述する吹出口31から空調室内Kに吹き出される。   Four main body outlets 15 between the heat exchanger 25 and the heat insulating member 14 on the inner peripheral surface of the side plate 11 and along each of the four sides of the main body unit 10 provided in the drain pan 60 were blown out from the blower fan 23. It becomes the ventilation path 17 which guides the air W to the blower outlet 31 of the decorative panel 3 mentioned later. The air W heat-exchanged with the refrigerant in the heat exchanger 25 passes through the air passage 17 and the main body outlet 15 and is blown out into the air-conditioned room K from an outlet 31 described later.

尚、本発明は後述する吹出用通路32と風向板4により、本体ユニット10と化粧パネル3の四隅に補助吹出口を設けなくても全方位へ吹き出すことができるものであり、本体吹出口15内には空気Wをさらに四隅に導く整流板191、192が設けられている。図2と図3と図13に示すように整流板191、192は本体吹出口15の長手方向の外側に向かう曲面を備え本体吹出口15内の2箇所に向かい合うように設けられている。整流板191は、後述する化粧パネル本体30に立設する軸受用支柱351方向に空気を送るものであり、整流板192は化粧パネル本体30に固定する後述するモータカバー44方向に空気を送るものである。軸受用支柱351方向は空気の抵抗となるものが無いため、多くの風を軸受用支柱351方向に導くように整流板191はきつい円弧状に形成される。一方、モータカバー44方向はモータカバー44が空気の抵抗となることで、軸受用支柱351方向よりも風が流れにくい。そのため整流板192は、整流板191よりも緩やかな円弧状に形成され、モータカバー44の下を通るように空気を導く。   In the present invention, the blowout passage 32 and the wind direction plate 4 which will be described later can be blown out in all directions without providing auxiliary blowouts at the four corners of the main unit 10 and the decorative panel 3. Inside, rectifying plates 191 and 192 for guiding the air W to the four corners are provided. As shown in FIG. 2, FIG. 3, and FIG. 13, the rectifying plates 191, 192 are provided with curved surfaces that extend outward in the longitudinal direction of the main body outlet 15 so as to face two locations in the main body outlet 15. The rectifying plate 191 sends air in the direction of a bearing column 351 standing on the decorative panel main body 30 described later, and the rectifying plate 192 sends air in the direction of a motor cover 44 fixed later on the decorative panel main body 30. It is. Since there is no air resistance in the bearing column 351 direction, the rectifying plate 191 is formed in a tight arc shape so as to guide a large amount of wind toward the bearing column 351. On the other hand, in the direction of the motor cover 44, the motor cover 44 serves as an air resistance, so that the wind is less likely to flow than in the direction of the bearing post 351. Therefore, the rectifying plate 192 is formed in a gentler arc shape than the rectifying plate 191, and guides air so as to pass under the motor cover 44.

前述したように本体ユニット10の底面101には図4に示す四角形の枠状板体で本体ユニット10の底面101と空気調和機1を天井面T1に取り付けた時に本体ユニット10の底面101周囲の天井面T1を覆う化粧パネル3が装着される。   As described above, the bottom surface 101 of the main unit 10 has a rectangular frame-shaped plate body shown in FIG. 4 and the periphery of the bottom surface 101 of the main unit 10 when the bottom surface 101 of the main unit 10 and the air conditioner 1 are attached to the ceiling surface T1.

The bearing support column 351 and the shaft portion 522 are respectively supported by the motor 43 housed in the motor cover. It is stably rotated by being pivotally supported at three places.

図5と図7に示すように化粧パネル本体30の接続部35の下(図7では上方)の角隅吹出部36には、4つの風向板5をそれぞれ回動するモータ43が配設される。モータ43は化粧パネル本体30に固定するモータ固定具を兼ねるモータカバー44内に収納され、モータカバー44と一体となって接続部35に固定される。   As shown in FIG. 5 and FIG. 7, motors 43 that respectively rotate the four wind direction plates 5 are disposed in the corner corner blow-out portion 36 below the connection portion 35 (upward in FIG. 7) of the decorative panel body 30. The The motor 43 is accommodated in a motor cover 44 that also serves as a motor fixing tool that is fixed to the decorative panel body 30, and is fixed to the connection portion 35 integrally with the motor cover 44.

接続部35には、一方の吹出口31側に軸受用支柱351を備え、他方の吹出口31側には接続部35の半面を占める一段落ち込んだ凹部が形成される。この凹部がモータカバー44を取り付けるモータカバー取付部352となる。   The connection portion 35 is provided with a bearing support column 351 on the side of one air outlet 31, and a recessed portion that is one step down and occupies a half surface of the connection portion 35 is formed on the other air outlet 31 side. This recess serves as a motor cover attachment portion 352 for attaching the motor cover 44.

モータカバー取付部352に取り付けるモータカバー44は、図7と図9と図10に示すように、モータカバー取付部352と当接する底部通路441と、外枠部33の縁面333に当接するモータ43を収納するモータ収納部442と、モータ収納部442から縁面333側に突出して設けた係止部447と、内枠部34の内壁部341に当接する壁面444と、壁面444よりモータ収納部442側で壁面444との間にパネル断熱部材45の一部を収納するリブ448と、壁面444から内枠部34のケーブル通路342に重なるように設けたフランジ449にネジ孔449aを備える。   As shown in FIGS. 7, 9, and 10, the motor cover 44 attached to the motor cover attaching portion 352 includes a bottom passage 441 that contacts the motor cover attaching portion 352 and a motor that contacts the edge surface 333 of the outer frame portion 33. 43, a locking portion 447 provided protruding from the motor storage portion 442 toward the edge surface 333, a wall surface 444 that contacts the inner wall portion 341 of the inner frame portion 34, and a motor storage from the wall surface 444. A rib 448 that houses a part of the panel heat insulating member 45 between the wall surface 444 on the side of the portion 442 and a screw hole 449 a in a flange 449 provided so as to overlap the cable passage 342 of the inner frame portion 34 from the wall surface 444.

底部通路441においてモータ収納部442の基端部441aが一段高くなっており、ここにモータ収納部442に収納されたモータ43のケーブル432を通しネジ孔449aの近傍からケーブル通路342に引き出すようになっている。   In the bottom passage 441, the base end portion 441a of the motor storage portion 442 is raised one step higher, and the cable 432 of the motor 43 stored in the motor storage portion 442 is passed through the cable passage 342 from the vicinity of the screw hole 449a. It has become.

ケーブル432を通したモータカバー44は、係止部447を化粧パネル本体30の外枠部33に設けた係止孔336に係止して、さらに内枠部34のケーブル通路342に設けたボス342aにフランジ449のネジ孔449aを螺着することで化粧パネル本体30に固定される。   The motor cover 44 through which the cable 432 is passed locks the locking portion 447 into the locking hole 336 provided in the outer frame portion 33 of the decorative panel body 30, and further the boss provided in the cable passage 342 of the inner frame portion 34. The screw hole 449a of the flange 449 is screwed to the 342a to be fixed to the decorative panel body 30.

これによりモータ43が吹出用通路32内に取り付けられ、さらに化粧パネルの表面から取り付け、取り外しが可能となることで、例えばモータ43のメンテナンス時に化粧パネル3を本体ユニット10から外す必要がなく作業性が改善される。   As a result, the motor 43 is mounted in the blowout passage 32, and can be further attached and detached from the surface of the decorative panel, so that it is not necessary to remove the decorative panel 3 from the main unit 10 during maintenance of the motor 43, for example. Is improved.

モータ収納部442は基端部441a側と化粧パネル3の対角線D側から吹出口31側が空調室Kに向かい突出する山型である。   The motor storage portion 442 has a mountain shape in which the outlet 31 side protrudes from the diagonal end D side of the base end portion 441a and the decorative panel 3 toward the air conditioning chamber K.

モータ収納部442は吹出口31側にモータ43の軸受部431を囲む軸受面446を備え、軸受面446は、モータ収納部442の山型の頂部から吹出口31側に向かって下方に傾斜する面となる。   The motor housing portion 442 includes a bearing surface 446 surrounding the bearing portion 431 of the motor 43 on the air outlet 31 side, and the bearing surface 446 is inclined downward from the mountain-shaped top of the motor housing portion 442 toward the air outlet 31 side. It becomes a surface.

モータカバー44は、軸受面446を傾斜面とすることで、図12に示すように角隅吹出部36に吹き出された空気W2の流れを遮ることを軽減することができる。   The motor cover 44 can reduce the blockage of the flow of the air W2 blown out to the corner corner blowing portion 36 as shown in FIG. 12 by making the bearing surface 446 an inclined surface.

図11に示すように接続部35のもう一方の吹出口31側に板状の軸受用支柱351が立設し、軸受用支柱351は先端に風向板5の軸部521を軸支する軸孔351aを備え、さらに軸孔351aと接続部35の間に空洞となる通気孔351bを設ける。   As shown in FIG. 11, a plate-like bearing support column 351 is erected on the other outlet 31 side of the connection portion 35, and the bearing support column 351 has a shaft hole that supports the shaft portion 521 of the wind direction plate 5 at the tip. 351a, and a vent hole 351b serving as a cavity is provided between the shaft hole 351a and the connecting portion 35.

軸受用支柱351に通気孔351bを設けることで、図12に示すように角隅吹出部36に向かう空気W1は通気孔351bを通ることで軸受用支柱351が抵抗となることを軽減して、多くの空気W1を導くことができる。また、軸受用支柱351に通気孔351bを設けることで、軸受用支柱351の吹出口31側と角隅吹出部36側とのそれぞれの面の間に温度差による結露の発生を防止することができ、軸受用支柱351に断熱材を貼付する必要がなくなる。   By providing the ventilation hole 351b in the bearing support column 351, the air W1 directed to the corner corner outlet portion 36 as shown in FIG. 12 reduces the resistance of the bearing support column 351 by passing through the ventilation hole 351b, A lot of air W1 can be led. Further, by providing the bearing post 351 with the vent hole 351b, it is possible to prevent the occurrence of condensation due to a temperature difference between the surfaces of the bearing post 351 on the outlet 31 side and the corner corner outlet 36 side. This eliminates the need to attach a heat insulating material to the bearing post 351.

次にそれぞれの部品を組み合わせた化粧パネル本体30と風向板5の回動による効果を説明する。まず空気調和機1の運転停止時は、図1と図4に示すように隣り合う4枚の風向板5で吸込グリルの周囲を囲む吹出用通路32全体を覆うことにより、風向板5が化粧パネルおよび吸込グリルと平行な線に視認され、意匠に統一感が生まれ意匠性が向上する。   Next, the effect by rotation of the decorative panel main body 30 and the wind direction board 5 which combined each component is demonstrated. First, when the operation of the air conditioner 1 is stopped, as shown in FIG. 1 and FIG. 4, the wind direction plate 5 is made up by covering the entire outlet passage 32 surrounding the suction grille with the adjacent four wind direction plates 5. Visible in a line parallel to the panel and the suction grille, the design is unified and the design is improved.

次に空気調和機1が運転を開始すると、図12に示すようにモータ43の軸受部431に軸支された風向板5の軸部522が回転する。これにより軸受部335に軸支された軸部511および軸受用支柱351に軸支された軸部521も回転する。回転に合わせて風向板5の第1辺部54側が吹出用通路32に向かって回動する。風向板5は最大で約60度まで回動する。   Next, when the air conditioner 1 starts operation, the shaft portion 522 of the wind direction plate 5 pivotally supported by the bearing portion 431 of the motor 43 rotates as shown in FIG. As a result, the shaft portion 511 supported by the bearing portion 335 and the shaft portion 521 supported by the bearing support column 351 also rotate. The first side 54 side of the wind direction plate 5 rotates toward the blowing passage 32 in accordance with the rotation. The wind direction plate 5 rotates up to about 60 degrees.

風向板5が回動すると、吸込グリル40側の第1辺部54が吹出用通路32内に移動し、第3辺部53と第4辺部56が角隅吹出部36まで潜り込む。化粧パネル本体30から突出するのは風向板5の第2辺部55の中で直線部551と第2円弧部552だけである。よって風向板5の端部が飛び出して見えることがなく、運転時でも風向板5を目立たせずに美観に優れた意匠となる。   When the wind direction plate 5 rotates, the first side portion 54 on the suction grill 40 side moves into the blowing passage 32, and the third side portion 53 and the fourth side portion 56 sink into the corner corner outlet portion 36. Only the straight portion 551 and the second arc portion 552 in the second side portion 55 of the wind direction plate 5 protrude from the decorative panel body 30. Therefore, the end portion of the wind direction plate 5 does not appear to protrude, and the design is excellent in aesthetic appearance without making the wind direction plate 5 conspicuous even during operation.

送風ファン23から吹き出された空気は、吹出口31を通り風向板5の風向部51に導かれて空気Wとして空調室Kへ勢いよく吹き出される。   The air blown from the blower fan 23 passes through the blowout port 31 and is guided to the wind direction portion 51 of the wind direction plate 5 and is blown out vigorously as the air W to the air conditioning room K.

一方、吹き出される空気Wの一部は図13を合わせて参照して、整流板191、192によって吹出口31の長手方向にも吹き出される。整流板191、192によって導かれた空気W1、W2は、風向板5の補助風向部52に沿って吹出用通路32の角部の角隅吹出部36まで導かれる。   On the other hand, a part of the blown-out air W is also blown out in the longitudinal direction of the blowout port 31 by the rectifying plates 191 and 192 with reference to FIG. The airs W1 and W2 guided by the rectifying plates 191 and 192 are guided along the auxiliary wind direction portion 52 of the wind direction plate 5 to the corner corner blowing portion 36 at the corner of the blowing passage 32.

整流板191によって軸受用支柱351方向に導かれた空気W1は、空気の抵抗となるものが無いため、多くの風が流れる。空気W1は軸受用支柱351の通気孔351bを通り抜け角隅吹出部36に至る。一方、整流板192によって導かれた空気W2は、モータカバー44が空気の抵抗となることで、軸受用支柱351方向よりも風が流れにくい。そこでモータカバー44の軸受面446を傾斜面とすることで、空気W2の流れを遮ることを軽減して角隅吹出部36に導く。   Since the air W1 guided in the direction of the bearing column 351 by the rectifying plate 191 has no air resistance, a lot of wind flows. The air W1 passes through the vent hole 351b of the bearing post 351 and reaches the corner corner outlet 36. On the other hand, the air W <b> 2 guided by the rectifying plate 192 is less likely to flow than the direction of the bearing column 351 because the motor cover 44 serves as air resistance. Therefore, by making the bearing surface 446 of the motor cover 44 an inclined surface, the flow of the air W2 is reduced and guided to the corner corner outlet 36.

空気W1と空気W2は角隅吹出部36で合流する。空気W1と空気W2では空気W1の方が多くの風が流れてきているため空気W1の方が勢いのある風となる。よって、空気W1の吹き出し方向に空気W2は引っ張られる。図13に示すように、吹出口31から吹き出された空気Wとともに空気W1と空気W2が合流して空気W3となった風が化粧パネル3の対角線Dよりも空気W1の吹き出し方向に傾いて吹き出される。空気W3は化粧パネル3の四辺に沿ってそれぞれ吹き出されることで空気Wとは異なる4方向に吹き出される。結果、全方位へ送風することが可能となり広い室内を効率的に空調する天井埋込型空気調和機1となる。   The air W <b> 1 and the air W <b> 2 merge at the corner corner blowing part 36. In the air W1 and the air W2, the air W1 is more vigorous because the air W1 has more wind flowing therethrough. Therefore, the air W2 is pulled in the blowing direction of the air W1. As shown in FIG. 13, the air W <b> 1 and the air W <b> 2 merge together with the air W blown from the blower outlet 31 to become the air W <b> 3, and the air W <b> 1 is inclined more than the diagonal line D of the decorative panel 3. Is done. The air W <b> 3 is blown out along the four sides of the decorative panel 3, so that the air W <b> 3 is blown out in four directions different from the air W. As a result, the ceiling-embedded air conditioner 1 that can blow air in all directions and efficiently air-conditions a large room is obtained.
