<天井埋込形空気調和機>
図1から図3に示す本発明による天井埋込形空気調和機1(以下、空気調和機1とする)は、空調室内Kの天井Tに埋設される箱型の筐体10と、同筐体の下面101に取り付ける四角形の化粧パネル3とからなる。筐体10は筐体10の側板11に複数備えられた取付金具12で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吊下げて設置される。また化粧パネル3は、空調室内K側から後述する取付部332を取付金具12にネジで固定することで筐体10に取り付けられ、筐体10の下面101と下面101周囲の空調室内K側の天井面Tを覆う。
<Embedded ceiling air conditioner>
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 includes a box-shaped casing 10 embedded in a ceiling T of an air-conditioned room K, and the same casing. The rectangular decorative panel 3 is attached to the lower surface 101 of the body. The casing 10 is installed by suspending a plurality of suspension bolts embedded in a ceiling back wall (not shown) with a plurality of mounting brackets 12 provided on the side plate 11 of the casing 10. The decorative panel 3 is attached to the housing 10 by fixing a mounting portion 332 (described later) to the mounting bracket 12 from the air-conditioned room K side with a screw. Cover the ceiling surface T.

<筐体>
筐体10の外郭は、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とで形成される。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。送風ファン23はファンモータ21とともに筐体10の内部のほぼ中央に配置される。
<Case>
The outer casing 10 is formed of a top plate 13 made of sheet metal and a side plate 11 extending downward from the outer periphery of the top plate 13. A heat insulating member 14 is provided on the inner peripheral surfaces of the top plate 13 and the side plate 11 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. The blower fan 23 and the fan motor 21 are disposed approximately at the center inside the housing 10.

図2と図3に示すように筐体10の下部はドレンパン60で覆われる。ドレンパン60は断熱部材61と後述するドレンパンプレート62でなる。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。   As shown in FIGS. 2 and 3, the lower portion of the housing 10 is covered with a drain pan 60. The drain pan 60 includes a heat insulating member 61 and a drain pan plate 62 described later. 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から室内の空気Wが筐体10内に吸い込まれる。筐体10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 indoor air W is sucked into the housing 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 casing 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、熱交換器25と対向する面に樹脂製のドレンパンプレート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. The drain pan 60 that receives the lower part of the heat exchanger 25 has a drain pan plate 62 made of resin integrally formed with the heat insulating member 61 made of foamed resin on the surface facing the heat exchanger 25 and drain water generated by the heat exchanger 25. Take it. 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周囲の断熱部材14との間と、ドレンパン60に設けられた筐体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を通り吹出口31から空調室内Kに吹き出される。   The four main body outlets 15 between the heat exchanger 25 and the heat insulating member 14 around the side plate 11 and along each of the four sides of the casing 10 provided in the drain pan 60 allow the air W blown from the blower fan 23 to flow. It becomes the ventilation path 17 which guides 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 from the outlet 31 into the air-conditioned room K.

尚、本発明は、後述する吹出用通路32と角隅吹出部36により、従来例のように補助吹出口を設けなくても全方位へ空気を吹き出すことができる。よって、ドレンパン60にも補助吹出口用の開口を設ける必要がないためドレンパン60の強度が保てることになる。   In the present invention, air can be blown out in all directions by a blowout passage 32 and a corner corner blowout portion 36 described later without providing an auxiliary blowout as in the conventional example. Therefore, since there is no need to provide an opening for the auxiliary air outlet in the drain pan 60, the strength of the drain pan 60 can be maintained.

<運転停止時>
空気調和機1の運転停止時は、図1と図4に示すように吹出用通路32(凹部32a)が吸込グリル40の周囲を囲み、隣り合う4枚の風向板5と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、吹出口31と風向板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。
<When operation is stopped>
When the operation of the air conditioner 1 is stopped, as shown in FIGS. 1 and 4, the blowout passage 32 (recessed portion 32 a) surrounds the suction grille 40, and the adjacent four wind direction plates 5 surround the suction grille. By covering the entire blowing passage 32 that surrounds the air outlet 31, the air outlet 31 and the wind direction plate 5 are visually recognized in a line parallel to the decorative panel and the suction grille, and a sense of unity is born and the design is improved.

<運転時>
空気調和機1が運転を開始すると、モータ43により図9と図10に示すようにモータ軸受431に軸支され風向板5の軸部522が回転する。これにより軸部511、521も回転して風向板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。
<During operation>
When the air conditioner 1 starts operation, the motor 43 pivotally supports the motor bearing 431 as shown in FIGS. 9 and 10 to rotate the shaft portion 522 of the wind direction plate 5. As a result, the shaft portions 511 and 521 are also rotated and the first side portion 54 side of the wind direction plate 5 is rotated toward the blowing passage 32. 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がモータカバー44の底部通路441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と傾斜部553の一部と第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 54 on the suction grill 40 side moves into the blowing passage 32, and the third side 53 and the fourth side 56 sink into the bottom passage 441 of the motor cover 44. Only the straight part 551, a part of the inclined part 553, and the second arc part 552 in the second side part 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.

また、図10に示すように風向板5の裏面58はモータカバー44の傾斜面442aとの間が狭くなり風が通りにくくなる。よって、吹出口31は風向板5の裏面58とモータカバー44のモータ収納部442の壁面444と外枠部33の縁面333と曲面334で囲まれた主吹出部311と、風向板5の表面57とパネル断熱部材45との間の補助吹出部312に分割される。補助吹出部312は吹出用通路32に繋がる。   Further, as shown in FIG. 10, the space between the back surface 58 of the wind direction plate 5 and the inclined surface 442 a of the motor cover 44 becomes narrow, and the wind does not easily pass. Therefore, the blower outlet 31 includes the back surface 58 of the wind direction plate 5, the wall surface 444 of the motor housing portion 442 of the motor cover 44, the main blowout portion 311 surrounded by the edge surface 333 and the curved surface 334 of the outer frame portion 33, The auxiliary blowout portion 312 between the surface 57 and the panel heat insulating member 45 is divided. The auxiliary blowing unit 312 is connected to the blowing passage 32.

送風ファン23から吹き出された空気は、図2に示すように送風ファン23のハブ23a側の風速が速く吹き出される空気の風量の多い。よって送風路17では断熱部材14寄りに流れる空気の風量が多いため吹出口31を通る空気Wの多くが主吹出部311から空調室内Kへ空気W1となって勢いよく吹き出される。   As shown in FIG. 2, the air blown from the blower fan 23 has a large amount of air blown at a high wind speed on the hub 23 a side of the blower fan 23. Therefore, in the air blowing path 17, the amount of air flowing toward the heat insulating member 14 is large, so most of the air W passing through the air outlet 31 is blown out vigorously as air W <b> 1 from the main blowout portion 311 to the air-conditioned room K.

一方、補助吹出部312から吹き出される空気は風速が遅いため広がりやすい。よって吹き出された空気W2の一部は、図11から図12に示すように風向板5の補助風向部52の表面57と吹出用通路32の間に沿って吹出用通路32の角隅まで導かれる。   On the other hand, the air blown out from the auxiliary blowing unit 312 tends to spread because the wind speed is slow. Accordingly, a part of the blown-out air W2 is guided to the corners of the blowing passage 32 along the space between the surface 57 of the auxiliary wind direction portion 52 of the wind direction plate 5 and the blowing passage 32 as shown in FIGS. It is burned.

隣り合う風向板5と吹出用通路32の角隅には、モータカバー44の底部通路441があり、隣り合う風向板5の補助風向部52とで角隅吹出部36を形成する。
風向板5の補助風向部52に導かれ吹出用通路32の角隅に至った空気W2は隣接する風向板5から導かれた空気W2とモータカバー44の底部通路441で合流する。
合流した空気W2は空間の空いている方向へ吹き吹出される。しかし、吸込グリル40側にはパネル断熱部材45の湾曲面453があり、一方、風向板5の補助風向部52の先端の第3辺部53と第4辺部56が底部通路441に潜り込んでいることで、対角線Dの外側へ間口が広く開口する。これにより、合流した空気W2は対角線Dの外側方向へ吹き出される。
There is a bottom passage 441 of the motor cover 44 at the corner of the adjacent wind direction plate 5 and the outlet passage 32, and the corner corner outlet 36 is formed by the auxiliary wind direction portion 52 of the adjacent wind direction plate 5.
The air W2 guided to the auxiliary wind direction portion 52 of the wind direction plate 5 and reaching the corner of the blowout passage 32 joins with the air W2 guided from the adjacent wind direction plate 5 in the bottom passage 441 of the motor cover 44.
The merged air W2 is blown out in a direction in which space is available. However, there is a curved surface 453 of the panel heat insulating member 45 on the suction grill 40 side, while the third side portion 53 and the fourth side portion 56 at the tip of the auxiliary wind direction portion 52 of the wind direction plate 5 sink into the bottom passage 441. As a result, the frontage opens widely to the outside of the diagonal line D. Thereby, the merged air W2 is blown out to the outside of the diagonal line D.

また風向板5の補助風向部52の表面57が、風向部51の表面57よりも水平方向に近い角度となることで、空気W2は、風向板5の補助風向部52表面から広い範囲に吹出されることになる。   Further, the surface 57 of the auxiliary wind direction portion 52 of the wind direction plate 5 has an angle closer to the horizontal direction than the surface 57 of the wind direction portion 51, so that the air W <b> 2 blows out from the surface of the auxiliary wind direction portion 52 of the wind direction plate 5 in a wide range. Will be.

以上の構成により、化粧パネル3に補助吹出口を設けなくても、補助吹出部312から吹き出される空気W2は風向板5の補助風向部52と吹出用通路32の間に沿って吹出用通路32の角隅まで導かれ、隣接する風向板5と吹出用通路32の角隅には、底部通路441があり、隣接する風向板5から導かれた空気W2と底部通路441で合流する。
合流した空気W2は空間の空いている方向へ吹き吹出されることから、隣接する風向板5の補助風向部52の先端から化粧パネル30の外へと吹き出されることで、従来例のように補助吹出口を設けずに、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となる。
With the above configuration, even if the decorative panel 3 is not provided with an auxiliary air outlet, the air W <b> 2 blown out from the auxiliary air outlet 312 flows between the auxiliary air direction portion 52 of the wind direction plate 5 and the air outlet passage 32. There are bottom passages 441 at the corners of the adjacent wind direction plate 5 and the blowout passage 32, and the air W2 guided from the adjacent wind direction plate 5 joins the bottom passage 441.
Since the merged air W2 is blown out in the direction in which the space is vacant, it is blown out of the decorative panel 30 from the tip of the auxiliary wind direction portion 52 of the adjacent wind direction plate 5, as in the conventional example. Without providing an auxiliary air outlet, it is possible to blow air in all directions, and it becomes a ceiling embedded type air conditioner that efficiently air-conditions a large room.
