上記吹出チャンバ４８は、図４（Ａ）（Ｂ）に示すように、吹出グリル５５と組になっており、吹出チャンバ４８の側板に固定された吊り金具４８Ａに、建屋３１の天井３２から垂下された吊りボルトを引っ掛けることによって、天井裏に設置されている。そして、吹出ダクト３６を経て送られる調和空気は、図中において矢印で示すように流れて、吹出グリル５５の二つの開口５５Ａを通じて、被調和室に吹き出される。   As shown in FIGS. 4 (A) and 4 (B), the blowout chamber 48 is paired with a blowout grill 55, and is suspended from the ceiling 32 of the building 31 by a hanging bracket 48 </ b> A fixed to the side plate of the blowout chamber 48. It is installed behind the ceiling by hooking a suspended bolt. The conditioned air sent through the blowing duct 36 flows as shown by arrows in the figure, and is blown out through the two openings 55A of the blowing grill 55 into the conditioned room.

上記吹出チャンバ４８は、図５（Ａ）に示すように、略箱状に形成された鋼板製の外装材８１と、この外装材８１の内側に配置され、その内側には、吹出空気の案内風路８３Ａ（図４（Ｂ）参照）が形成された発泡スチロール製の風路形成体８３と、この風路形成体８３を覆う略板状の鋼板製の蓋材８５とで構成されている。これらは、図５（Ｂ）に示すように組み立てられ、その後に、図４（Ａ）に示すように、補強板８７、及びダクト接続フランジ９０がねじ止めされる。   As shown in FIG. 5 (A), the blowout chamber 48 is disposed inside the outer casing 81 made of a steel plate formed in a substantially box shape and inside the outer casing 81. The air passage 83A (see FIG. 4B) is formed of a polystyrene foam air passage forming body 83 and a substantially plate-shaped steel plate lid member 85 covering the air passage forming body 83. These are assembled as shown in FIG. 5 (B), and then the reinforcing plate 87 and the duct connection flange 90 are screwed as shown in FIG. 4 (A).

上記風路形成体８３は、図５（Ａ）に示すように、二つの形成体８３Ｂ，８３Ｃに分割されており、一方の形成体８３Ｂには、吹出ダクト３６に連通する風孔８３Ｄがあけられている。そして、他方の形成体８３Ｃの内壁面には、図４（Ｂ）に示すように、風の案内面８３Ｅが形成され、この案内面８３Ｅは、吹出開口部に向けて徐々に突出量が増し、上記風孔８３Ｄの最下点の延長線Ｌ上より若干吹出開口部側に近づく位置、即ち位置８３Ｆで、最も高くなるように形成されている。   As shown in FIG. 5A, the air path forming body 83 is divided into two forming bodies 83B and 83C, and an air hole 83D communicating with the blowout duct 36 is formed in one of the forming bodies 83B. It has been. As shown in FIG. 4B, a wind guide surface 83E is formed on the inner wall surface of the other forming body 83C, and the amount of protrusion of this guide surface 83E gradually increases toward the blowout opening. The air hole 83D is formed so as to be the highest at a position that is slightly closer to the outlet opening side than the extension line L at the lowest point of the air hole 83D, that is, at a position 83F.

本構成では、図５（Ｂ）に示すように、各形成体８３Ｂ，８３Ｃの各面に、外装材８１又は蓋材８５のいずれかに当接する突起部８９が形成されており、それ以外の形成体８３Ｂ，８３Ｃの面には、外装材８１又は蓋材８５に当接することのない凹部９１が形成されている。また、上述した突起部８９は、それぞれの形成体８３Ｂ，８３Ｃにおける各面の最外周周縁部のすべてと、一方の形成体８３Ｂにおける風孔８３Ｄの周縁部のすべてとに一体形成されている。また、図５（Ａ）を参照し、蓋材８５に、風量調整板９３が配設されている。この風量調整板９３は、風孔８３Ｄ相当位置に設けられ、略円弧状の切り欠き９３Ａ、及び略直線状の切り欠き９３Ｂで切り抜かれた、蓋材８５の残存部によって形成され、当該風量調整板９３は、一対の連結部９３Ｃを介して蓋材８５に折り曲げ自在に連結される。この場合、風量の調整は、風量調整板９３を、形成体８３Ｂの風孔８３Ｄ内に押し込むように、一対の連結部９３Ｃを中心に矢印Ｘの方向に折り曲げることによって行う。風量調整板９３を大きく折り曲げれば風量が増し、反対に、折り曲げ量をすくなくすれば風量が減る。本構成では、風量調整板９３が、略円弧状の切り欠き９３Ａ、及び略直線状の切り欠き９３Ｂで切り抜かれた、蓋材８５の残存部により形成されるため、余分な部材を必要とすることなく、風量調整板９３を簡単に形成することができる。   In this configuration, as shown in FIG. 5 (B), projections 89 that contact either the exterior material 81 or the cover material 85 are formed on the respective surfaces of the formed bodies 83B and 83C. Concave portions 91 that do not come into contact with the exterior material 81 or the lid material 85 are formed on the surfaces of the formed bodies 83B and 83C. Further, the above-described protrusions 89 are integrally formed on all of the outermost peripheral edge portions of the respective surfaces of the respective formed bodies 83B and 83C and all of the peripheral edge portions of the air holes 83D in the one formed body 83B. In addition, referring to FIG. 5A, an air volume adjusting plate 93 is disposed on the lid member 85. The air volume adjusting plate 93 is provided at a position corresponding to the air hole 83D, and is formed by a remaining portion of the lid member 85 cut out by a substantially arc-shaped notch 93A and a substantially linear notch 93B. The plate 93 is foldably connected to the lid member 85 via a pair of connecting portions 93C. In this case, the air volume is adjusted by bending the air volume adjusting plate 93 in the direction of the arrow X around the pair of connecting portions 93C so as to be pushed into the air holes 83D of the forming body 83B. If the air volume adjusting plate 93 is largely bent, the air volume increases, and conversely, if the bending amount is reduced, the air volume decreases. In this configuration, since the air volume adjusting plate 93 is formed by the remaining portion of the lid member 85 cut out by the substantially arc-shaped cutout 93A and the substantially linear cutout 93B, an extra member is required. Therefore, the air volume adjusting plate 93 can be easily formed.

吹出グリル５５は、図６に示すように、樹脂製の外装体１０５と、この外装体１０５に積層配置される発泡スチロール製の断熱体１０６とを備えて構成されている。符号１０７は、風向変更羽根である。外装体１０５の裏面には、矩形状の立ち上がり部１０５Ａが形成され、この立ち上がり部１０５Ａは、断熱体１０６に設けられた２つの開口１０６Ａ内に嵌め合わされ、これによって、図７に示すように、この吹出グリル５５には、二つの開口（横長の通風路）５５Ａが形成される。立ち上がり部１０５Ａの上縁部の４隅には、図６に示すように、箱状に突出する支持部１０８（引っ掛け部）が形成されている。   As shown in FIG. 6, the blow-out grill 55 includes a resin exterior body 105 and a polystyrene foam heat insulator 106 that is stacked on the exterior body 105. Reference numeral 107 denotes a wind direction changing blade. A rectangular rising portion 105A is formed on the back surface of the exterior body 105, and the rising portion 105A is fitted into two openings 106A provided in the heat insulating body 106, thereby, as shown in FIG. The blow grill 55 is formed with two openings (laterally long ventilation passages) 55A. As shown in FIG. 6, support portions 108 (hook portions) protruding in a box shape are formed at the four corners of the upper edge portion of the rising portion 105A.

この支持部１０８は、図７に示すように、立ち上がり部１０５Ａの上縁部に一体的に形成され、その上面部には、貫通孔１０９〜１１２があけられ、この貫通孔１０９〜１１２は、吹出グリル５５の開口５５Ａに臨んでいる。   As shown in FIG. 7, the support portion 108 is formed integrally with the upper edge portion of the rising portion 105 </ b> A, and through holes 109 to 112 are formed in the upper surface portion thereof. It faces the opening 55A of the blowout grill 55.

図８に示すように、４つの貫通孔１０９〜１１２の内、二つの開口５５Ａにおける一方の側の各端部Ａに位置する貫通孔１０９，１１０は長孔であり、他方の側の各端部Ｂに位置する貫通孔１１１，１１２は丸孔１１１Ａ，１１２Ａと、これに連続する切り欠き１１１Ｂ，１１２Ｂとで構成されている。本実施形態では、貫通孔１１１，１１２が形成された支持部１０８が引っ掛け部となる。   As shown in FIG. 8, among the four through-holes 109 to 112, the through-holes 109 and 110 located at the respective end portions A on one side of the two openings 55A are long holes, and the respective ends on the other side. The through holes 111 and 112 located in the part B are constituted by round holes 111A and 112A and cutouts 111B and 112B continuous thereto. In the present embodiment, the support portion 108 in which the through holes 111 and 112 are formed serves as a hook portion.

つぎに、図９（Ａ）〜（Ｄ）を参照して、吹出グリル５５を吹出チャンバ４８に取り付ける際の手順について説明する。   Next, with reference to FIGS. 9A to 9D, a procedure for attaching the blowing grill 55 to the blowing chamber 48 will be described.

まず、図９（Ａ）に示すように、吹出チャンバ４８における鋼板製の外装材８１の下面８１Ａに、ねじ１０１、１０２を仮止めしておく。続いて、図９（Ｂ）に示すように、上記仮止めしたねじ１０１、１０２の頭部１０１Ａ、１０２Ａに、吹出グリル５５の支持部１０８に形成された貫通孔１１１，１１２を引っ掛ける。この場合、貫通孔１１１，１１２は、丸孔１１１Ａ，１１２Ａと、これに連続する切り欠き１１１Ｂ，１１２Ｂとで構成されているため、吹出グリル５５を横方向（図中Ｚ方向）にスライドさせ、切り欠き１１
１Ｂ、１１２Ｂを通じて、丸孔１１１Ａ，１１２Ａに、上記仮止めしたねじ１０１、１０２を進入させる。 First, as shown in FIG. 9A, screws 101 and 102 are temporarily fixed to the lower surface 81 </ b> A of the steel sheet exterior material 81 in the blowing chamber 48. Subsequently, as shown in FIG. 9B, the through holes 111 and 112 formed in the support portion 108 of the blowing grill 55 are hooked on the head portions 101A and 102A of the screws 101 and 102 that are temporarily fixed. In this case, since the through holes 111 and 112 are constituted by the round holes 111A and 112A and the cutouts 111B and 112B continuous thereto, the blow grill 55 is slid in the lateral direction (Z direction in the figure) Notch 11
The temporarily fixed screws 101 and 102 are inserted into the round holes 111A and 112A through 1B and 112B.

この状態で、いわゆる仮止めが完了する。すなわち、吹出グリル５５は、図９（Ｃ）に示すように、ねじ１０１、１０２側が引っ掛かった状態で支持され、吹出グリル５５の他端５５Ｂが下方に傾斜した状態で、落下することなく仮止めされる。   In this state, so-called temporary fixing is completed. That is, as shown in FIG. 9C, the blowout grill 55 is supported in a state where the screws 101 and 102 are hooked, and the other end 55B of the blowout grill 55 is inclined downward without being dropped. Is done.

続いて、吹出グリル５５の他端５５Ｂを持ち上げ、この他端５５Ｂ側に形成した支持部１０８の貫通孔１０９，１１０を通じて、ねじ１０３、１０４を本止めし、あわせて、上記仮止めしたねじ１０１、１０２をも本止めする。これによって、図９（Ｄ）に示すように、吹出グリル５５を吹出チャンバ４８に取り付ける作業は終了する。   Subsequently, the other end 55B of the blow grill 55 is lifted, and the screws 103 and 104 are finally fixed through the through holes 109 and 110 of the support portion 108 formed on the other end 55B side. , 102 is also stopped. As a result, as shown in FIG. 9D, the work of attaching the blowing grill 55 to the blowing chamber 48 is completed.

本実施形態によれば、吹出グリル５５の支持部１０８に切り欠き１１１Ｂ、１１２Ｂを形成し、この切り欠き１１１Ｂ、１１２Ｂを通じて、支持部１０８を吹出チャンバ４８に仮止めしたねじの頭部１０１Ａ、１０２Ａに引っ掛けることにより、吹出グリル５５を吹出チャンバ４８に仮止めすることができるため、吹出グリル５５から両手を離して、すべてのねじ１０１〜１０４を本止めすることができ、吹出グリル５５を容易に吹出チャンバ４８に取り付けることができる。   According to the present embodiment, notches 111B and 112B are formed in the support portion 108 of the blowout grill 55, and the screw heads 101A and 102A in which the support portion 108 is temporarily fixed to the blowout chamber 48 through the cutouts 111B and 112B. Since the blowout grill 55 can be temporarily fixed to the blowout chamber 48 by being hooked onto the blowout grille 55, both hands can be released from the blowout grill 55, and all the screws 101 to 104 can be permanently fixed. It can be attached to the blowing chamber 48.

この場合、この支持部１０８は、箱状に形成されたことにより、仮止め状態の吹出グリル５５を一時的に保持する剛性を備えるため、吹出グリル５５から両手を離しても、吹出グリル５５の落下が防止される。   In this case, since the support portion 108 is formed in a box shape, the support portion 108 has rigidity to temporarily hold the temporarily fixed blowing grill 55. Therefore, even if both hands are separated from the blowing grill 55, the blowing grill 55 Falling is prevented.

また、支持部１０８は、吹出グリル５５の樹脂製の外装体１０５に一体に形成されているため、吹出グリル５５の部品点数を少なくすることができ、組立工程を簡略化することができる。   Moreover, since the support part 108 is integrally formed with the resin-made exterior body 105 of the blowing grill 55, the number of parts of the blowing grill 55 can be reduced, and the assembling process can be simplified.

また、本実施形態によれば、貫通孔１１１，１１２が設けられる支持部１０８は、各開口５５Ａにおける同一側の各端部Ｂに臨むように設けられているため、これら開口５５Ａを通じて、上記支持部１０８を目視することができ、この支持部１０８を容易に仮止めしたねじの頭部１０１Ａ、１０２Ａに引っ掛けることができる。   In addition, according to the present embodiment, the support portion 108 provided with the through holes 111 and 112 is provided so as to face each end B on the same side in each opening 55A. The portion 108 can be visually observed, and the supporting portion 108 can be easily hooked on the screw heads 101A and 102A temporarily fixed.

また、本実施形態では、本来、吹出グリル５５の本止めに使用するねじ１０１〜１０４の一部を吹出チャンバ４８における鋼板製の外装材８１の下面８１Ａに仮止めし、この仮止めしたねじの頭部１０１Ａ、１０２Ａに支持部１０８を引っ掛けるように構成されているため、従来のように、余分な仮止め用の機構を設ける必要がなく、従って、部品点数を増やすことなく、吹出グリル５５を吹出チャンバ４８に仮止めすることができる。   In the present embodiment, a part of the screws 101 to 104 that are originally used to fix the blowing grill 55 is temporarily fixed to the lower surface 81A of the steel sheet exterior member 81 in the blowing chamber 48. Since the support portion 108 is configured to be hooked on the head portions 101A and 102A, it is not necessary to provide an extra temporary fixing mechanism as in the prior art. It can be temporarily fixed to the blowing chamber 48.

本構成では、風向変更羽根１０７は、図６に示すように、この風向変更羽根１０７の中央部１０７Ａの幅が広く、両端部１０７Ｂの幅が狭くなるように構成されている。従って、風向変更羽根１０７を取り外すことなく、図７に矢印Ｙで示すように、幅狭の両端部１０７Ｂに形成される隙間から、ドライバ等の工具を挿入して、ねじの本止めを行うことができる。   In this configuration, as shown in FIG. 6, the wind direction changing blade 107 is configured such that the width of the central portion 107A of the wind direction changing blade 107 is wide and the width of both end portions 107B is narrow. Therefore, without removing the wind direction changing blade 107, as shown by an arrow Y in FIG. 7, a tool such as a screwdriver is inserted from the gap formed at the narrow end portions 107B and the screw is fixed. Can do.
