　空調装置は、本体１、多翼式送風機２、化粧グリル６、高電圧ユニット５を備える。図２は、実施の形態１にかかる空調装置を上面から見た図である。図３は、実施の形態１にかかる空調装置を下面から見た図であって、化粧グリル６を取り外した状態を示す図である。 The air conditioner includes a main body 1, a multi-blade blower 2, a decorative grill 6, and a high voltage unit 5. FIG. 2 is a diagram of the air conditioner according to the first embodiment as viewed from above. FIG. 3 is a diagram of the air conditioner according to the first embodiment as viewed from the lower surface, and shows a state where the decorative grill 6 is removed.
　本体１は、樹脂で形成された箱体形状を呈する。本体１の一面には、図３に示すように、開口２７が形成される。開口２７は、本体１の内部に空気を取り込むための取込口２７ａと、本体１の内部から空気を吐き出すための吐出口２７ｂとに区分される。本体１の内部には、図１において矢印で示すように、取込口２７ａと吐出口２７ｂとを連通させる流路が形成される。本体１には、開口２７の周囲に張り出すフランジ１ａが形成されている。フランジ１ａは、取付面である天井２６と平行に張り出しているとも換言できる。本体１の上部には、回転式構造で容易に外部電源電線と接続可能な端子台８と、回路収納ケース９内に制御回路１０を備えている。 The main body 1 has a box shape made of resin. As shown in FIG. 3, an opening 27 is formed on one surface of the main body 1. The opening 27 is divided into an intake port 27 a for taking air into the main body 1 and an outlet port 27 b for discharging air from the inside of the main body 1. As shown by an arrow in FIG. 1, a flow path that connects the intake port 27 a and the discharge port 27 b is formed inside the main body 1. The main body 1 is formed with a flange 1 a that protrudes around the opening 27. In other words, the flange 1a projects in parallel with the ceiling 26 that is the mounting surface. At the upper part of the main body 1, a terminal block 8 that can be easily connected to an external power supply wire with a rotary structure, and a control circuit 10 in a circuit storage case 9 are provided.
　送風機である多翼式送風機２は、本体１の内部に形成された流路に設けられる。多翼式送風機２は、モーター７の駆動軸に結合されたファン３が回転することで、取込口２７ａから吐出口２７ｂに向かう空気流を流路内に発生させる。多翼式送風機２は、ファン３を収容するファンケーシング４を備える。図４は、実施の形態１におけるファンケーシング４の斜視図である。ファンケーシング４には、空気を取り込むための開口が形成される。 A multi-blade blower 2 that is a blower is provided in a flow path formed inside the main body 1. The multi-blade blower 2 generates an air flow from the intake port 27a to the discharge port 27b in the flow path when the fan 3 coupled to the drive shaft of the motor 7 rotates. The multi-blade fan 2 includes a fan casing 4 that houses the fan 3. FIG. 4 is a perspective view of fan casing 4 in the first embodiment. An opening for taking in air is formed in the fan casing 4.
　図５は、実施の形態１にかかる空調装置の側面図である。化粧グリル６は、開口２７およびフランジ１ａと対向する板状の部材である。化粧グリル６は、開口２７およびフランジ１ａから離間して配置される。化粧グリル６は、閉じた状態において、空調装置の意匠性の向上およびファン３への異物混入の防止の機能を発揮する。化粧グリル６は樹脂製の一体成形物である。化粧グリル６のうち、開口２７およびフランジ１ａと対向する対向面２８の裏面側となる外側面２９は、平坦面とされている。 FIG. 5 is a side view of the air conditioner according to the first embodiment. The decorative grill 6 is a plate-like member facing the opening 27 and the flange 1a. The decorative grill 6 is disposed away from the opening 27 and the flange 1a. In the closed state, the decorative grill 6 exhibits the functions of improving the design of the air conditioner and preventing foreign matter from entering the fan 3. The decorative grill 6 is an integrally molded product made of resin. In the decorative grill 6, the outer surface 29 which is the back surface side of the facing surface 28 facing the opening 27 and the flange 1 a is a flat surface.
　化粧グリル６は、図５に示すように、化粧グリル６に形成された軸６ａと爪６ｂが、本体１に形成された軸受部１ｄ、爪１ｅにそれぞれ嵌合させることで本体１に固定される。図６は、実施の形態１にかかる空調装置の化粧グリルを開いた状態を示す図である。化粧グリル６の爪６ｂを、本体１の爪１ｅから外すことで、図６に示すように軸６ａ、軸受部１ｄを中心として化粧グリル６が回転可能となり、化粧グリル６を開くことができる。 As shown in FIG. 5, the decorative grill 6 is fixed to the main body 1 by fitting a shaft 6a and a claw 6b formed on the decorative grill 6 to a bearing 1d and a claw 1e formed on the main body 1, respectively. The FIG. 6 is a diagram illustrating a state where the decorative grill of the air conditioner according to the first embodiment is opened. By removing the claw 6b of the decorative grill 6 from the claw 1e of the main body 1, the decorative grill 6 can be rotated around the shaft 6a and the bearing 1d as shown in FIG. 6, and the decorative grill 6 can be opened.
　図１に戻って、空調装置には、開口２７およびフランジ１ａと化粧グリル６との間の空間を、開口２７と垂直な方向から見て第１の領域３１と第２の領域３２とに区分するリブ３０が設けられている。第１の領域３１は、本体１の取込口２７ａと対向する。第２の領域３２は、本体１の吐出口２７ｂと対向する。 Returning to FIG. 1, in the air conditioner, the space between the opening 27 and the flange 1 a and the decorative grill 6 is divided into a first region 31 and a second region 32 when viewed from the direction perpendicular to the opening 27. Ribs 30 are provided. The first region 31 faces the intake port 27a of the main body 1. The second region 32 faces the discharge port 27b of the main body 1.
　図７は、実施の形態１にかかる空調装置を下面側から見た斜視図であって、化粧グリル６を取り外した状態を示す図である。図８は、実施の形態１における化粧グリル６を対向面２８側から見た斜視図である。空調装置に設けられるリブ３０は、本体１のフランジ１ａに形成されたフランジリブ１ｆ（図７を参照）と、化粧グリル６の対向面２８に形成されたグリルリブ６ｃ（図８を参照）と、ファンケーシング４に形成されたケーシングリブ４ｃとを組み合わせて構成される。より具体的には、開口２７と対向する領域においてグリルリブ６ｃとケーシングリブ４ｃとが高さ方向に重なり、その両側にフランジリブ１ｆが設けられることで、開口２７およびフランジ１ａと化粧グリル６との間の空間を第１の領域３１と第２の領域３２とに区分するリブ３０が構成される。この構成によって、リブ３０は、フランジ１ａ（化粧グリル６）の端部から他の端部まで延びるリブ３０となる。これにより、第１の領域３１および第２の領域３２の両方に、少なくともフランジ１ａ（化粧グリル６）の端面領域が含まれることとなる。 FIG. 7 is a perspective view of the air conditioner according to the first embodiment when viewed from the lower surface side, and shows a state where the decorative grill 6 is removed. FIG. 8 is a perspective view of the decorative grill 6 according to Embodiment 1 as viewed from the facing surface 28 side. The rib 30 provided in the air conditioner includes a flange rib 1f (see FIG. 7) formed on the flange 1a of the main body 1, and a grill rib 6c (see FIG. 8) formed on the facing surface 28 of the decorative grill 6. The casing rib 4c formed on the fan casing 4 is combined. More specifically, the grill rib 6c and the casing rib 4c overlap in the height direction in a region facing the opening 27, and flange ribs 1f are provided on both sides thereof, so that the opening 27, the flange 1a, and the decorative grill 6 A rib 30 that divides the space between the first region 31 and the second region 32 is formed. With this configuration, the rib 30 becomes a rib 30 extending from the end of the flange 1a (the decorative grill 6) to the other end. As a result, both the first region 31 and the second region 32 include at least the end surface region of the flange 1a (the decorative grill 6).
　図９は、実施の形態１におけるフランジリブ１ｆ部分を拡大した図である。リブ３０のうち化粧グリル６の外周に近接する端部となる部分、すなわち本実施の形態におけるフランジリブ１ｆは、第２の領域３２側を向く面に、リブ３０の中央側から端部側に向かうにしたがって、第１の領域３１から離れて第２の領域３２側に向かう離間面３３が形成される。例えば、フランジ１ａの幅が２５ｍｍである場合、端部から１２．５ｍｍの範囲に離間面３３を形成する。離間面３３は、フランジリブ１ｆのうち第１の領域側を向く面とがなす角度を３０°とする。本実施の形態１では、フランジリブ１ｆがリブ３０の中央側から端部側に向かうにしたがって幅が広がることで、離間面３３が形成される。離間面３３が形成される部分は三角柱形状を呈している。 FIG. 9 is an enlarged view of the flange rib 1f portion in the first embodiment. A portion of the rib 30 which is an end portion close to the outer periphery of the decorative grill 6, that is, the flange rib 1 f in the present embodiment, is a surface facing the second region 32 side, from the center side of the rib 30 to the end side. As it goes, a separation surface 33 that is away from the first region 31 and toward the second region 32 is formed. For example, when the width of the flange 1a is 25 mm, the separation surface 33 is formed in a range of 12.5 mm from the end. The spacing surface 33 has an angle of 30 ° with the surface of the flange rib 1f facing the first region. In the first embodiment, the flange rib 1 f is widened from the center side to the end side of the rib 30, whereby the separation surface 33 is formed. The portion where the separation surface 33 is formed has a triangular prism shape.
　図１０は、実施の形態１におけるフランジ１ａと化粧グリル６との間のうち第２の領域３２の外周部分を拡大した部分拡大断面図である。図１０に示すように、第２の領域３２にあるフランジ１ａには、フランジ１ａの外周に向かうにしたがって化粧グリル６に近づく傾斜面３４が形成される。また、化粧グリル６のうち、傾斜面３４と対向する部分には、化粧グリル６の外周と平行に延びる突部６ｄが形成される（図８も参照）。なお、傾斜面３４は、第１の領域３１にあるフランジ１ａにも形成されていてもよい。 FIG. 10 is a partial enlarged cross-sectional view in which the outer peripheral portion of the second region 32 is enlarged between the flange 1a and the decorative grill 6 in the first embodiment. As shown in FIG. 10, the flange 1a in the second region 32 is formed with an inclined surface 34 that approaches the decorative grill 6 toward the outer periphery of the flange 1a. Further, a protruding portion 6d extending in parallel with the outer periphery of the decorative grill 6 is formed on a portion of the decorative grill 6 facing the inclined surface 34 (see also FIG. 8). Note that the inclined surface 34 may also be formed on the flange 1 a in the first region 31.
　例えば、フランジ１ａの幅が２５ｍｍであり、フランジ１ａの外周端と化粧グリル６の外周端との間隔が１１ｍｍである場合に、傾斜面３４の傾斜角度を１２°とし、傾斜面３４の外周側端部とフランジ１ａの外周端との間を２ｍｍとする。また、化粧グリル６の外周端から内側に２０ｍｍとなる位置に高さ３ｍｍで突部６ｄが形成される。 For example, when the width of the flange 1a is 25 mm and the distance between the outer peripheral end of the flange 1a and the outer peripheral end of the decorative grill 6 is 11 mm, the inclination angle of the inclined surface 34 is 12 °, and the outer peripheral side of the inclined surface 34 The distance between the end and the outer peripheral end of the flange 1a is 2 mm. Further, a protrusion 6d is formed at a height of 3 mm at a position 20 mm inward from the outer peripheral end of the decorative grill 6.
　空調装置では、多翼式送風機２が運転されてファン３が回転することで、取込口２７ａから本体１の内部に空気が取り込まれ、本体１の内部の流路を通して吐出口２７ｂから空気が吐出される。これにより、フランジ１ａと化粧グリル６との間から第１の領域３１に空気が吸い込まれるとともに、第２の領域３２からフランジ１ａと化粧グリル６との間を通して空気が吹き出される。すなわち、フランジ１ａと化粧グリル６との間のうち、第１の領域３１の外周部分は空気を吸い込む吸込口となり、第２の領域３２の外周部分は空気を吹き出す吹出口となる。したがって、空調装置では、リブ３０を挟んで吸込口と吹出口とが隣接することとなる。 In the air conditioner, when the multi-blade blower 2 is operated and the fan 3 rotates, air is taken into the main body 1 from the intake port 27a, and air is discharged from the discharge port 27b through the flow path inside the main body 1. Discharged. Thus, air is sucked into the first region 31 from between the flange 1 a and the decorative grill 6, and air is blown out from the second region 32 between the flange 1 a and the decorative grill 6. That is, between the flange 1a and the decorative grill 6, the outer peripheral portion of the first region 31 becomes a suction port for sucking air, and the outer peripheral portion of the second region 32 becomes a blower outlet for blowing out air. Therefore, in the air conditioner, the inlet and the outlet are adjacent to each other with the rib 30 interposed therebetween.
　ここで、吸込口と吹出口の境界となるリブ３０（フランジリブ１ｆ）には、離間面３３が形成されているため、リブ３０に沿って吹き出される空気は、第１の領域３１から離れる方向（図９の矢印Ｘに示す方向）に誘導される。そのため、第２の領域３２から吹き出された空気が、すぐに第１の領域３１から吸い込まれてしまうショートサーキットが生じにくくなる。 Here, since the separation surface 33 is formed on the rib 30 (flange rib 1 f) serving as a boundary between the suction port and the air outlet, the air blown along the rib 30 is separated from the first region 31. It is guided in the direction (the direction indicated by the arrow X in FIG. 9). Therefore, a short circuit in which the air blown from the second region 32 is immediately sucked from the first region 31 is less likely to occur.
　このように、吸込口と吹出口とを、フランジ１ａと化粧グリル６との間の空間で隣接させても、ショートサーキットの発生を抑えることができるので、吸込口または吹出口の一方を化粧グリル６の外側面２９に形成せずに済む。また、ショートサーキットの発生を抑えるために化粧グリル６の外側面に凹凸を設ける必要がなくなり、外側面２９を平坦面とすることができる。これにより、空調装置の意匠性の向上を図ることができる。また、外側面２９を平坦面とすることで、加工コストを抑えることができるため、空調装置の製造コストの抑制を図ることができる。 Thus, even if the suction port and the air outlet are adjacent to each other in the space between the flange 1a and the decorative grill 6, the occurrence of a short circuit can be suppressed, so that one of the air inlet or the air outlet is connected to the decorative grill. 6 does not need to be formed on the outer side surface 29 of the sixth. Further, it is not necessary to provide irregularities on the outer surface of the decorative grill 6 in order to suppress the occurrence of a short circuit, and the outer surface 29 can be made flat. Thereby, the designability of an air conditioner can be improved. Moreover, since the processing cost can be suppressed by making the outer surface 29 a flat surface, the manufacturing cost of the air conditioner can be suppressed.
　また、フランジ１ａと化粧グリル６との隙間から吹き出される空気が天井２６に接触すると、天井面が汚れてしまうおそれがある。一方、本実施の形態１では、フランジ１ａに形成された傾斜面３４によって、フランジ１ａと化粧グリル６との隙間から吹き出される空気が、天井２６から離れる方向（図１０の矢印Ｙに示す方向）に誘導されるため、天井が汚れにくくなる。また、化粧グリル６の対向面２８に形成された突部６ｄによって、空気の流れが一旦傾斜面３４側に向けられることで、その後の傾斜面３４による空気の誘導の効果をより確実に発揮させることができる。また、空調装置から吹き出された空気が天井２６に接触するのを防ぐために、化粧グリル６の外側面２９に吹出口を形成する必要がないため、空調装置の意匠性の向上を図ることができる。なお、傾斜面３４を、第１の領域３１にあるフランジ１ａにも形成すれば、空調装置が吸い込む空気が天井２６に接触して天井面が汚れることを抑えることができる。 Further, when the air blown out from the gap between the flange 1a and the decorative grill 6 contacts the ceiling 26, the ceiling surface may become dirty. On the other hand, in the first embodiment, the air blown from the gap between the flange 1a and the decorative grill 6 is separated from the ceiling 26 by the inclined surface 34 formed on the flange 1a (the direction indicated by the arrow Y in FIG. 10). ), The ceiling is difficult to get dirty. In addition, the air flow is once directed to the inclined surface 34 side by the protrusion 6d formed on the facing surface 28 of the decorative grill 6, so that the effect of air induction by the subsequent inclined surface 34 is more reliably exhibited. be able to. Moreover, since it is not necessary to form a blower outlet in the outer surface 29 of the decorative grill 6 in order to prevent the air blown out from the air conditioner from coming into contact with the ceiling 26, it is possible to improve the design of the air conditioner. . If the inclined surface 34 is also formed on the flange 1a in the first region 31, it is possible to prevent the air sucked by the air conditioner from contacting the ceiling 26 and contaminating the ceiling surface.
　空調装置は、フランジ１ａに８箇所設けた固定ねじ取付部１ｂ（図３を参照）を利用し、４箇所以上に木ねじ等の固定ねじで天井２６へ固定される。 The air conditioner is fixed to the ceiling 26 with fixing screws such as wood screws at four or more locations using fixing screw mounting portions 1b (see FIG. 3) provided at eight locations on the flange 1a.
　図１１は、実施の形態１における埃取フィルター２３の斜視図である。図３および図７に示すように、埃取フィルター２３は、本体１の取込口２７ａを覆うように設置される。ファンケーシング４には、埃取フィルター２３を固定するための固定部４ａおよび爪引掛部４ｂが形成される。固定部４ａおよび爪引掛部４ｂにそれぞれ埃取フィルター２３の固定部２３ａおよび爪部２３ｂを固定、嵌合させることで埃取フィルター２３をファンケーシング４に固定する。埃取フィルター２３には、着脱時に把持可能な把持部２３ｃが形成されている。 FIG. 11 is a perspective view of the dust filter 23 in the first embodiment. As shown in FIGS. 3 and 7, the dust filter 23 is installed so as to cover the intake port 27 a of the main body 1. The fan casing 4 is formed with a fixing part 4a and a claw hooking part 4b for fixing the dust filter 23. The dust removal filter 23 is fixed to the fan casing 4 by fixing and fitting the fixing portion 23a and the claw portion 23b of the dust removal filter 23 to the fixation portion 4a and the claw hooking portion 4b, respectively. The dust removal filter 23 is formed with a grip portion 23c that can be gripped when attached or detached.
