　副本体２０は、図３および図４に示すように、一側部２１、中央部２３、他側部２２のそれぞれ上縁から壁面１側へ延びてその壁面１に接する上面部２４を含むとともに、一側部２１、中央部２３、他側部２２のそれぞれ下縁から壁面１側へ延びてその壁面１に接する下面部２５を含む。また、副本体２０は、中央部２３から上面部２４にかけて空気吸込口２６を有し、その空気吸込口２６と対応する位置に塵埃除去用の網状のフィルタ２７を着脱自在に保持する。さらに、副本体２０は、下面部２５に空気吹出口２８を有する。この空気吹出口２８は、主本体１０への取付けに伴い、主本体１０の後述する上下方向ルーバ１７によって開閉自在に閉塞される。 As shown in FIGS. 3 and 4, the sub-main body 20 includes an upper surface portion 24 extending from the upper edge of each of the one side portion 21, the central portion 23, and the other side portion 22 toward the wall surface 1 and in contact with the wall surface 1. Includes a lower surface portion 25 extending from the lower edge of each of the one side portion 21, the central portion 23, and the other side portion 22 toward the wall surface 1 and in contact with the wall surface 1. Further, the sub-main body 20 has an air suction port 26 from the central portion 23 to the upper surface portion 24, and a net-like filter 27 for removing dust is detachably held at a position corresponding to the air suction port 26. Further, the sub-main body 20 has an air outlet 28 on the lower surface portion 25. The air outlet 28 is rotatably closed by the vertical louver 17 described later of the main body 10 as it is attached to the main body 10.
　副本体２０の上面部２４のうち、一側部２１の側面２１ａと連なる部位は側面２１ａの湾曲形状に沿う曲線形状を有し、一側部２１の側面２１ｂと連なる部位は側面２１ｂの平面形状に沿う直線形状を有する。副本体２０の上面部２４のうち、他側部２２の側面２２ａと連なる部位は他側部２２の湾曲形状に沿う曲線形状を有し、他側部２２の側面２２ｂと連なる部位は側面２２ｂの平面形状に沿う直線形状を有する。一側部２１および他側部２２のそれぞれ上部は緩やかな傾斜をもって上面部２１に連なる。 Of the upper surface portion 24 of the sub-main body 20, the portion connected to the side surface 21a of the one side portion 21 has a curved shape along the curved shape of the side surface 21a, and the portion connected to the side surface 21b of the one side portion 21 has a planar shape of the side surface 21b. It has a linear shape along. Of the upper surface portion 24 of the sub-main body 20, the portion connected to the side surface 22a of the other side portion 22 has a curved shape along the curved shape of the other side portion 22, and the portion connected to the side surface 22b of the other side portion 22 is the side surface 22b. It has a linear shape along a planar shape. The upper portions of the one side portion 21 and the other side portion 22 are connected to the upper surface portion 21 with a gentle inclination.
　同様に、副本体２０の下面部２５のうち、一側部２１の側面２１ａと連なる部位は側面２１ａの湾曲形状に沿う曲線形状を有し、一側部２１の側面２１ｂと連なる部位は側面２１ｂの平面形状に沿う直線形状を有する。副本体２０の下面部２５のうち、他側部２２の側面２２ａと連なる部位は他側部２２の湾曲形状に沿う曲線形状を有し、他側部２２の側面２２ｂと連なる部位は側面２２ｂの平面形状に沿う直線形状を有する。 Similarly, of the lower surface portion 25 of the sub-main body 20, the portion connected to the side surface 21a of the one side portion 21 has a curved shape along the curved shape of the side surface 21a, and the portion connected to the side surface 21b of the one side portion 21 is the side surface 21b. It has a linear shape along the plane shape of. Of the lower surface portion 25 of the sub-main body 20, the portion connected to the side surface 22a of the other side portion 22 has a curved shape along the curved shape of the other side portion 22, and the portion connected to the side surface 22b of the other side portion 22 is the side surface 22b. It has a linear shape along a planar shape.
　一側部２１の側面２１ｂに２つの挿通孔２９が形成され、他側部２２の側面２２ｂに２つの挿通孔２９が形成されている。これら挿通孔２９に固定具たとえば螺子４０がそれぞれ挿通される。挿通される各螺子４０は、主本体１０における後板１１の四隅に形成されている切欠き１１ａをそれぞれ通り、壁面１の上部の４ヶ所の位置１ａにそれぞれ螺合される。これら螺子４０の螺合により、一側部２１の側面２１ｂおよび他側部２２の側面２３ｂのそれぞれ端縁が主本体１０の後板１１の四隅を壁面１との間に挟んだ状態で壁面１に押し付けられ、主本体１０および副本体２０が互いに締結された状態で壁面１に固定される。すなわち、主本体１０および副本体２０の組立て体である室内ユニット本体８０を壁面１から浮き上がることなく壁面１に密着した状態で固定することができる。室内ユニット本体８０及び後述する前面パネル３０は、その両側の端部を壁面１まで伸ばしているため、左右方向に長い形状をしている。また、据付け板２は極力材料を減らすために横幅寸法が小さく作られている。実際の据付け板２の横寸法は、室内熱交換器１２や室内ファンの幅寸法とほぼ同じか、それよりも短い。したがって、室内ユニット本体８０の両側部は、据付け板２よりもかなり側方にはみ出る。このため、室内ユニット本体８０の両側部は、壁面１から離れる方向に浮き上りやすい。それに対して、上述のような螺子固定を行うことで、室内ユニット本体８０の壁面１からの浮き上がりを防止することができる。なお、この螺子４０による固定は設置状況に対応じて必要に応じて実施することができる。 Two insertion holes 29 are formed on the side surface 21b of the one side portion 21, and two insertion holes 29 are formed on the side surface 22b of the other side portion 22. Fixtures such as screws 40 are inserted into these insertion holes 29, respectively. Each screw 40 to be inserted passes through the notches 11a formed at the four corners of the rear plate 11 in the main body 10, and is screwed into the four positions 1a at the upper part of the wall surface 1, respectively. By screwing these screws 40, the wall surface 1 is in a state where the end edges of the side surface 21b of the one side portion 21 and the side surface 23b of the other side portion 22 sandwich the four corners of the rear plate 11 of the main body 10 between the wall surface 1 and the wall surface 1. The main body 10 and the sub-main body 20 are fixed to the wall surface 1 in a state of being fastened to each other. That is, the indoor unit main body 80, which is an assembly of the main main body 10 and the sub main body 20, can be fixed in close contact with the wall surface 1 without rising from the wall surface 1. The indoor unit main body 80 and the front panel 30 described later have long shapes in the left-right direction because the ends on both sides thereof extend to the wall surface 1. Further, the installation plate 2 is made to have a small width dimension in order to reduce the material as much as possible. The horizontal dimension of the actual installation plate 2 is almost the same as or shorter than the width dimension of the indoor heat exchanger 12 and the indoor fan. Therefore, both side portions of the indoor unit main body 80 protrude considerably to the side of the installation plate 2. Therefore, both side portions of the indoor unit main body 80 tend to rise in the direction away from the wall surface 1. On the other hand, by fixing the screws as described above, it is possible to prevent the indoor unit main body 80 from rising from the wall surface 1. The fixing with the screw 40 can be performed as needed according to the installation situation.
　なお、壁面１の材質によっては、壁面１への螺子４０の螺合が困難な場合がある。この場合でも、後板１１の外周縁と副本体２０の内周縁とが螺子止め及び係合しているので、一側部２１および他側部２２の端縁と壁面１との間に大きな隙間は生じない。したがって、螺子４０による追加固定は設置状況に対応じて必要に応じて実施される。 Depending on the material of the wall surface 1, it may be difficult to screw the screw 40 onto the wall surface 1. Even in this case, since the outer peripheral edge of the rear plate 11 and the inner peripheral edge of the sub-main body 20 are screwed and engaged, a large gap is provided between the edge of the one side portion 21 and the other side portion 22 and the wall surface 1. Does not occur. Therefore, the additional fixing by the screw 40 is carried out as necessary according to the installation situation.
　主本体１０に対する副本体２０の取付けに伴い、他側部２２の内側の空間が上記電気部品箱１４の収容スペースとなる。他側部２２の側面２２ａは、電気部品箱１４の蓋部を露出させるための開口２２ｃを有する。この開口２２ｃを通して電気部品箱１４の蓋体を開閉操作することができる。電気部品箱１４は、他側部２２の側面２２ａの湾曲形状に合わせ、主本体１０の厚み方向に対し傾斜した状態で取付けられている。 With the attachment of the sub-main body 20 to the main body 10, the space inside the other side portion 22 becomes the storage space for the electric component box 14. The side surface 22a of the other side portion 22 has an opening 22c for exposing the lid portion of the electric component box 14. The lid of the electric component box 14 can be opened and closed through the opening 22c. The electric component box 14 is attached in a state of being inclined with respect to the thickness direction of the main body 10 in accordance with the curved shape of the side surface 22a of the other side portion 22.
　なお、図３に示すように、一側部２１における側面２１ａの下部２１ａｘ、側面２１ｂの下部２１ｂｘ、中央部２３の下部２３ｘ、他側部２２における側面２２ａの下部２２ａｘ、側面２２ｂの下部２２ｂｘは、後述する帯状の弾性部材７０の取付け領域となる。なお、中央部２３の下部２３ｘのみを帯状の弾性部材７０の取付け領域としてもよい。 As shown in FIG. 3, the lower portion 21ax of the side surface 21a on the one side portion 21, the lower portion 21bx of the side surface 21b, the lower portion 23x of the central portion 23, the lower portion 22ax of the side surface 22a on the other side portion 22, and the lower portion 22bx of the side surface 22b are This is a mounting area for the strip-shaped elastic member 70, which will be described later. It should be noted that only the lower portion 23x of the central portion 23 may be used as the attachment region for the strip-shaped elastic member 70.
　また、図３に示すように、側面２１ａの下部２１ａｘ、中央部２３の下部２３ｘ、側面２２ａの下部２２ａｘには、弾性部材７０が取付けられる領域より上方の位置に、それぞれ係止用孔７１が形成されている。副本体２０に対する前面パネル３０の取付けに際し、前面パネル３０の裏面側に形成されている後述の図１０に示す係止爪３５がこれら係止用孔７１に入り込み、緩やかに保持される。 Further, as shown in FIG. 3, locking holes 71 are provided in the lower portion 21ax of the side surface 21a, the lower portion 23x of the central portion 23, and the lower portion 22ax of the side surface 22a at positions above the region where the elastic member 70 is attached. It is formed. When the front panel 30 is attached to the sub-main body 20, the locking claws 35 shown in FIG. 10 described later, which are formed on the back surface side of the front panel 30, enter the locking holes 71 and are gently held.
　主本体１０に対する副本体２０の取付け後、副本体２０の前面側を被うように一体成形された合成樹脂からなる白色、乳白色もしくはクリーム色の前面パネル（化粧パネルあるいはグリルパネルともいう）３０が取付けられる。このように空気調和機の室内ユニットは、主本体１０、副本体２０及びこの前面パネル３０から構成される。前面パネル３０は、副本体２０における一側部２１、中央部２３、他側部２２とほぼ同じ形状の一側部３１、中央部３３、他側部３２を有し、当該前面パネル３０の上縁に取付けられている一対のリブ３４，３５によって副本体２０へ着脱自在に取付けられる。 After the sub-main body 20 is attached to the main body 10, a white, milky white or cream-colored front panel (also referred to as a decorative panel or grill panel) 30 made of synthetic resin integrally molded so as to cover the front side of the sub-main body 20 is formed. Can be installed. As described above, the indoor unit of the air conditioner is composed of the main body 10, the sub-main body 20, and the front panel 30 thereof. The front panel 30 has one side portion 21, a central portion 23, and one side portion 31, a central portion 33, and another side portion 32 having substantially the same shape as the other side portion 22 in the sub-main body 20, and is above the front panel 30. It is detachably attached to the sub-main body 20 by a pair of ribs 34 and 35 attached to the edge.

　なお、中央部３３を平面形状としたが、左右方向に曲率の大きい緩やかな曲面としてもよい。なお、側面３１aと側面３１ｂ及び側面３１ｂと中央部３３の接続部分、側面３２aと側面３２ｂ及び側面３２ｂと中央部３３の接続部分については、図面上、接続部分であることを示す上下方向に沿う線を描画しているが、これら複数の面の接続部分は実際にはほぼ滑らかな曲面形状を有する。したがって、各接続部分の面の曲率や面形状の変化はほとんど目立たず、外観においてその各接続部分に明確な線が出ることはない。 Although the central portion 33 has a planar shape, it may be a gentle curved surface having a large curvature in the left-right direction. The connection portion between the side surface 31a and the side surface 31b and the side surface 31b and the central portion 33, and the connection portion between the side surface 32a and the side surface 32b and the side surface 32b and the central portion 33 are along the vertical direction indicating that they are connection portions in the drawing. Although the lines are drawn, the connecting portions of these plurality of surfaces actually have a nearly smooth curved surface shape. Therefore, changes in the curvature and surface shape of the surface of each connecting portion are hardly noticeable, and no clear line appears in each connecting portion in appearance.
　前面パネル３０を副本体２０に取付けるためのリブ３４，３５は、図３に示すように、係止用の突起３４ａ，３５ａを先端に有する。副本体２０への取付けに際し、リブ３４，３５は、太線矢印で示すように、人為的な操作により互いに反対方向に押し拡げられながら、副本体２０の一側部２１の上部に形成されているスリット４１および他側部２２の上部に形成されているスリット４２に挿入される。この挿入後、リブ３４，３５に対する押し拡げの操作が解除されると、リブ３４，３５が合成樹脂自身の弾性によって元の状態に戻る。これに伴い、リブ３４，３５の突起３４ａ，３５ａがスリット４１，４２の内側の係止用部材に係合し、前面パネル３０の上縁が副本体２０の上部に回動自在に係止される。この係止の状態で前面パネル３０を副本体２０の中央部２３に向け押し下げ、かつ前面パネル３０の裏面側の下部に存する後述の各係止爪３５を副本体２０の各係止用孔７１に入れて後述の各フック７２に係合させることにより、副本体２０に対する前面パネル３０の取付けが完了する。前面パネル３０を副本体２０への取付けが完了した状態では、前面パネル３０の左右端、すなわち側面３１ｂ、３２ｂの左右端部は壁面に接するか、もしくはごくわずかの隙間しかない位置まで壁面１に延びることになる。 As shown in FIG. 3, the ribs 34 and 35 for attaching the front panel 30 to the sub-main body 20 have protrusions 34a and 35a for locking at the tips. When attached to the sub-main body 20, the ribs 34 and 35 are formed on the upper portion of one side portion 21 of the sub-main body 20 while being expanded in opposite directions by artificial operation as shown by the thick arrow. It is inserted into the slit 42 formed in the upper part of the slit 41 and the other side portion 22. After this insertion, when the operation of pushing and expanding the ribs 34 and 35 is released, the ribs 34 and 35 return to their original states due to the elasticity of the synthetic resin itself. Along with this, the protrusions 34a and 35a of the ribs 34 and 35 engage with the locking members inside the slits 41 and 42, and the upper edge of the front panel 30 is rotatably locked to the upper part of the sub-body 20. Slit. In this locked state, the front panel 30 is pushed down toward the central portion 23 of the sub-main body 20, and each of the locking claws 35 described later located in the lower portion on the back surface side of the front panel 30 is provided with each locking hole 71 of the sub-main body 20. By putting it in the hook and engaging it with each hook 72 described later, the attachment of the front panel 30 to the sub-main body 20 is completed. When the front panel 30 has been attached to the sub-main body 20, the left and right ends of the front panel 30, that is, the left and right ends of the side surfaces 31b and 32b are in contact with the wall surface or on the wall surface 1 to a position where there is only a slight gap. It will be extended.
　一方、係止爪３５とフック７２との係合は、合成樹脂からなる係止爪３５とフック７２の弾性で保持された緩い係合であるため、取付け時と反対の操作を行えば、前面パネル３０を副本体２０から簡単に取り外すことができる。 On the other hand, the engagement between the locking claw 35 and the hook 72 is a loose engagement held by the elasticity of the locking claw 35 made of synthetic resin and the hook 72. The panel 30 can be easily removed from the sub-body 20.
　以上、主本体１０、副本体２０、および前面パネル３０により、当該室内ユニットが構成される。 As described above, the indoor unit is composed of the main body 10, the sub-main body 20, and the front panel 30.
　前面パネル３０の一側部３１および他側部３２が中央部３３と連なる部位から壁面１側へそれぞれ湾曲する形状を有し、その湾曲する部位から先の部分が壁面１に対し鋭角の状態でその壁面１まで延びる構成なので、見かけ上、当該室内ユニットが壁面１から滑らかに膨らみつつ壁面１とほぼ同一面を成すように壁面１に一体化する。また、室内の照明が当該室内ユニットに当たっても、室内ユニットの影が壁面１に生じ難くなる。これらの点は、当該室内ユニットの美観の向上につながり、かつ、使用者に対する壁面上部に取付けられた室内ユニットによる威圧感を大幅に緩和することができる。 One side portion 31 and the other side portion 32 of the front panel 30 have a shape curved from a portion connected to the central portion 33 toward the wall surface 1, and the portion beyond the curved portion has an acute angle with respect to the wall surface 1. Since the structure extends to the wall surface 1, the indoor unit is apparently integrated with the wall surface 1 so as to swell smoothly from the wall surface 1 and form substantially the same surface as the wall surface 1. Further, even if the indoor lighting hits the indoor unit, the shadow of the indoor unit is less likely to be cast on the wall surface 1. These points lead to the improvement of the aesthetic appearance of the indoor unit, and can significantly reduce the intimidating feeling of the indoor unit attached to the upper part of the wall surface to the user.
　さらに、当該室内ユニットの壁面への据付け状態では、室内ユニット本体８０、すなわち副本体２０、は、室内方向となる前方全体が前面パネル３０によって覆われることになる。このため、従来のように室内ユニット本体の前面のみが前面パネル３０によって覆われ、本体８０の両側面が室内に露出している場合に比べ、室内ユニット本体８０の左右両側面が、前面パネル３０によって全体的にカバーされるため、室内ユニット本体８０の両側面がほこりなどで汚れることがない。その代わりに前面パネル３０の前面にほこりなどが付着するが、前面パネル３０は壁面に至るまで滑らかな面で構成されており、掃除が容易であり、かつ汚れがひどい場合には容易に取り外すことができ、取り外し後に、水道水等で洗浄することも可能であり、衛生的である。 Further, in the state of being installed on the wall surface of the indoor unit, the front panel 30 covers the entire front of the indoor unit main body 80, that is, the sub-main body 20, which is in the indoor direction. Therefore, as compared with the conventional case where only the front surface of the indoor unit main body is covered by the front panel 30 and both side surfaces of the main body 80 are exposed indoors, the left and right side surfaces of the indoor unit main body 80 are the front panel 30. Since it is totally covered by the air, both sides of the indoor unit main body 80 are not contaminated with dust or the like. Instead, dust or the like adheres to the front surface of the front panel 30, but the front panel 30 is composed of a smooth surface up to the wall surface, is easy to clean, and can be easily removed when it is heavily soiled. It is hygienic because it can be washed with tap water after removal.
　[ファブリック部材について]　
　前面パネル３０はそのままでも使用可能であるが、必要に応じて、図５に示す装飾用のファブリック(布)部材５０を装着することができる。このファブリック部材５０は、前面パネル３０とほぼ同じ大きさの矩形形状を有し、前面パネル３０への装着によりその前面パネル３０の表面を被うもので、当該室内ユニットの美観をさらに向上させるための種々の色や柄のものを用意することができる。
これによりファブリック部材５０を選定することで色味を合わせて壁面に同化させて目立たなくさせたり、逆に目立たせたりすることもできる。 [About fabric members]
The front panel 30 can be used as it is, but if necessary, the decorative fabric member 50 shown in FIG. 5 can be attached. The fabric member 50 has a rectangular shape having substantially the same size as the front panel 30, and covers the surface of the front panel 30 when mounted on the front panel 30, in order to further improve the aesthetic appearance of the indoor unit. Various colors and patterns can be prepared.
As a result, by selecting the fabric member 50, it is possible to match the colors and assimilate them into the wall surface to make them inconspicuous, or conversely, to make them conspicuous.
　ファブリック部材５０の装着に際しては、帯状の４本の面ファスナー（第１面ファスナー）６１がファブリック部材５０の裏面の周縁に例えば糸の縫付けにより取付けられるとともに、前面パネル３０の裏面側の周縁にも４本の面ファスナー（第２面ファスナー）６２が例えば両面テープにより取付けられる。 When the fabric member 50 is attached, four strip-shaped surface fasteners (first surface fasteners) 61 are attached to the peripheral edge of the back surface of the fabric member 50, for example, by sewing a thread, and on the peripheral edge of the back surface side of the front panel 30. Also, four hook-and-loop fasteners (second hook-and-loop fasteners) 62 are attached by, for example, double-sided tape.
　すなわち、図６に示すように、ファブリック部材５０の裏面の一側縁５１，他側縁５２，上縁５３，下縁５４に帯状の面ファスナー６１がそれぞれ縫付けられる。次に、図７に示すようにファブリック部材５０の一側縁５１および他側縁５２が表面側から裏面側に折り曲げられ、続いて図８に示すようにファブリック部材５０の上縁５３および下縁５４が表面側から裏面側に折り曲げられる。そして、上縁５３の折り曲げ片の両端と一側縁５１および他側縁５２との重なり部位５５，５６が縫付け結合されるとともに、下縁５４の折り曲げ片の両端と一側縁５１および他側縁５２との重なり部位５７，５８が糸で縫付け結合される。 That is, as shown in FIG. 6, a strip-shaped hook-and-loop fastener 61 is sewn on one side edge 51, the other side edge 52, the upper edge 53, and the lower edge 54 of the back surface of the fabric member 50, respectively. Next, as shown in FIG. 7, one side edge 51 and the other side edge 52 of the fabric member 50 are bent from the front surface side to the back surface side, and subsequently, as shown in FIG. 8, the upper edge 53 and the lower edge of the fabric member 50 are bent. 54 is bent from the front surface side to the back surface side. Then, the overlapping portions 55 and 56 of the bent piece of the upper edge 53 and the one side edge 51 and the other side edge 52 are sewn and connected, and both ends of the bent piece of the lower edge 54 and the one side edge 51 and others are sewn together. The overlapping portions 57 and 58 with the side edge 52 are sewn and connected with a thread.
　この折り返しおよび縫付け結合により、ファブリック部材５０の裏面の四辺に袋状部が前面パネル３０への装着用としてそれぞれ形成され、その袋状部の内側に存する面ファスナー６１はファブリック部材５０の裏面に対向する状態となる。 By this folding and sewing connection, bag-shaped portions are formed on the four sides of the back surface of the fabric member 50 for mounting on the front panel 30, and the hook-and-loop fastener 61 existing inside the bag-shaped portion is formed on the back surface of the fabric member 50. It will be in a state of facing each other.
　面ファスナー６１は例えば多数のループ状繊維を配列してなるループ型で、面ファスナー６２は例えば多数のフック状繊維を配列してなるフック型であり、両者を押し付けることで両者が互いに係合し、両者を引き離すことで両者の係合を解除することができる。 The hook-and-loop fastener 61 is, for example, a loop type in which a large number of loop-shaped fibers are arranged, and the hook-and-loop fastener 62 is, for example, a hook type in which a large number of hook-shaped fibers are arranged. , Both can be disengaged by pulling them apart.
　ファブリック部材５０を前面パネル３０に装着する場合、前面パネル３０の周縁をファブリック部材５０の袋状部に収め、ファブリック部材５０の周縁の折り返し片を前面パネル３０の周縁に対して抑え込むことにより、ファブリック部材５０側の面ファスナー６１が前面パネル３０側の面ファスナー６２に係合する。この係合により、ファブリック部材５０を前面パネル３０にしっかり装着することができる。ファブリック部材５０は伸縮性が低い布地を用いることが好適である。伸縮性が高いと前面パネル３０への取付けが難しくなる。ただし、伸縮性が低い布地では組付けるときにファブリックが捩れやすくなったり波打ったりするという問題が生じる。しかしながら、本実施形態の前面パネル３０は、曲面部分のRが大きく、壁面１に至る傾斜もなだらかで、ファブリック部材５０の取付け面が凸面となっている。さらに前面パネル３０が合成樹脂の一体成型品であり、素材自体に弾性変形し、元の形状への復元力があることから、ファブリック部材５０の取付け後には捩れや波打ちが生じにくく、きれいに、かつ簡単に取付けることができる。 When the fabric member 50 is attached to the front panel 30, the peripheral edge of the front panel 30 is housed in the bag-shaped portion of the fabric member 50, and the folded piece of the peripheral edge of the fabric member 50 is pressed against the peripheral edge of the front panel 30 to hold the fabric. The hook-and-loop fastener 61 on the member 50 side engages with the hook-and-loop fastener 62 on the front panel 30 side. By this engagement, the fabric member 50 can be firmly attached to the front panel 30. It is preferable to use a fabric having low elasticity for the fabric member 50. If the elasticity is high, it becomes difficult to attach it to the front panel 30. However, with a fabric with low elasticity, there is a problem that the fabric tends to twist or wavy when assembled. However, in the front panel 30 of the present embodiment, the curved surface portion has a large radius, the slope to the wall surface 1 is gentle, and the mounting surface of the fabric member 50 is convex. Further, since the front panel 30 is an integrally molded product of synthetic resin, the material itself is elastically deformed and has a restoring force to the original shape, so that twisting and waviness are unlikely to occur after the fabric member 50 is attached, and it is clean and clean. It can be easily installed.
　ファブリック部材５０を装着した前面パネル３０が副本体２０に取付けられた状態を主本体１０内の構成とともに図９に断面して示し、その図９における面ファスナー６１，６２の係合状態を図１０に拡大して示している。図９および図１０は共に室内ユニットの略中央部分における縦断面である。 The state in which the front panel 30 to which the fabric member 50 is attached is attached to the sub-main body 20 is shown in cross section in FIG. 9 together with the configuration inside the main body 10, and the engaged state of the hook-and- loop fasteners 61 and 62 in FIG. 9 is shown in FIG. It is enlarged and shown in. 9 and 10 are both vertical cross-sections in the substantially central portion of the indoor unit.
　主本体１０は、室内熱交換器１２を前面と背面にわたり３つ折りのコの字型に成形して配置し、その室内熱交換器１２の内側に室内ファン１３を配置し、その室内ファン１３から空気吹出口２８に通じる風路に左右方向ルーバ１６および上下方向ルーバ１７を順次に配置してなる。 In the main body 10, the indoor heat exchanger 12 is formed and arranged in a U-shape folded in three over the front and the back, and the indoor fan 13 is arranged inside the indoor heat exchanger 12 from the indoor fan 13. The left-right direction louver 16 and the up-down direction louver 17 are sequentially arranged in the air passage leading to the air outlet 28.
　副本体２０の下部２１ａｘ，下部２１ｂｘ，下部２３ｘ，下部２２ａｘ，下部２２ｂｘに、帯状のスポンジ等からなる押圧により弾性変形するとともに実質的に気密にできる弾性部材７０が取付けられている。 An elastic member 70 that can be elastically deformed and substantially airtight by pressing a band-shaped sponge or the like is attached to the lower portion 21ax, lower portion 21bx, lower portion 23x, lower portion 22ax, and lower portion 22bx of the sub-main body 20.
　弾性部材７０が取付けられる下部２１ａｘ，２３ｘ，２２ａｘには図３にも示した係止用孔７１がそれぞれ形成されており、副本体２０に対する前面パネル３０の取付けに際し、前面パネル３０の裏面側に形成されている突起状の複数の係止爪３５がこれら係止用孔７１に入り込む。入り込んだ各係止爪３５は、各係止用孔７１と対応する位置に配置されている各フック７２をその各フック７２の弾性偏倚力に抗しながら上方に一旦押し上げ、押し上げた各フック７２の弾性復元力を受けた状態で各フック７２と係合する。この係合により、副本体２０に対する前面パネル３０の取付けが完了する。 Locking holes 71 also shown in FIG. 3 are formed in the lower portions 21ax, 23x, and 22ax to which the elastic member 70 is attached, respectively. A plurality of protruding locking claws 35 formed enter the locking holes 71. Each of the locking claws 35 that has entered pushes up each hook 72 arranged at a position corresponding to each locking hole 71 upward while resisting the elastic eccentric force of each hook 72, and pushes up each hook 72. Engage with each hook 72 while receiving the elastic restoring force of. By this engagement, the attachment of the front panel 30 to the sub-main body 20 is completed.
　ファブリック部材５０が装着された前面パネル３０を副本体２０に取付けると、少なくともファブリック部材５０の袋状部の折り返し片の外周面が弾性部材７０に当接し、その当接によって副本体２０内への通気が遮断される。例えば図１０に矢印で示すように、空気吹出口２８から吹出された空気やその周辺の空気が副本体２０の下部に流れ込もうとしても、それらの空気が副本体２０内および主本体１０内に流入する不具合を防ぐことができる。これにより、副本体２０内および主本体１０内の不要な結露を回避することができる。 When the front panel 30 to which the fabric member 50 is mounted is attached to the sub-main body 20, at least the outer peripheral surface of the folded piece of the bag-shaped portion of the fabric member 50 abuts on the elastic member 70, and the abutment causes the abutment into the sub-main body 20. Ventilation is blocked. For example, as shown by an arrow in FIG. 10, even if the air blown out from the air outlet 28 and the air around it try to flow into the lower part of the sub-main body 20, those airs are inside the sub-main body 20 and the main body 10. It is possible to prevent the trouble of flowing into the air. This makes it possible to avoid unnecessary dew condensation in the sub-main body 20 and the main body 10.
　ファブリック部材５０を装着していない前面パネル３０が副本体２０に取付けられた状態を主本体１０内の構成とともに図１１に断面して示し、その図１１における面ファスナー６２と弾性部材７０との接触状態を図１２に拡大して示している。 A state in which the front panel 30 to which the fabric member 50 is not attached is attached to the sub-main body 20 is shown in cross section in FIG. 11 together with the configuration inside the main body 10, and the contact between the hook-and-loop fastener 62 and the elastic member 70 in FIG. 11 is shown. The state is enlarged and shown in FIG.
　この場合、前面パネル３０の裏面の周縁および面ファスナー６２が弾性部材７０に当接し、その当接によって副本体２０内への通気が遮断される。例えば図１２に矢印で示すように、空気吹出口２８から吹出された空気やその周辺の空気が副本体２０の下部に流れ込んでも、それらの空気が副本体２０内および主本体１０内に流入する不具合を防ぐことができる。図１０と図１２を比較して分かる様に、ファブリック部材５０を装着した図１０の場合には、図１２に比べてファブリック部材５０の厚み分だけ弾性部材７０が圧縮されて薄くなっている。このような圧縮可能な弾性部材７０を使用することで、ファブリック部材５０を前面パネル３０に装着した場合及びしない場合のいずれにおいても副本体２０内への通気を遮断することができる。 In this case, the peripheral edge of the back surface of the front panel 30 and the hook-and-loop fastener 62 abut on the elastic member 70, and the abutment blocks the ventilation into the sub-main body 20. For example, as shown by an arrow in FIG. 12, even if the air blown out from the air outlet 28 and the air around it flow into the lower part of the sub-main body 20, those airs flow into the sub-main body 20 and the main body 10. It is possible to prevent problems. As can be seen by comparing FIGS. 10 and 12, in the case of FIG. 10 in which the fabric member 50 is attached, the elastic member 70 is compressed and thinned by the thickness of the fabric member 50 as compared with FIG. By using such a compressible elastic member 70, it is possible to block the ventilation into the sub-main body 20 regardless of whether the fabric member 50 is attached to the front panel 30 or not.
　また、ファブリック部材５０を前面パネル３０に装着した場合、前面パネル３０の代わりにファブリック部材５０にほこりなどが付着する。上述の通り、ファブリック部材５０は容易に取り付け、取り外しが可能であるため、汚れがひどい場合にはファブリック部材５０を前面パネル３０から取り外し、ファブリック部材５０だけを洗濯やクリーニングすることが可能であり、衛生的である。 Further, when the fabric member 50 is attached to the front panel 30, dust or the like adheres to the fabric member 50 instead of the front panel 30. As described above, since the fabric member 50 can be easily attached and detached, it is possible to remove the fabric member 50 from the front panel 30 and wash or clean only the fabric member 50 when it is heavily soiled. It is hygienic.
　［変形例］　
　上記実施形態では、一側部２１における側面２１ａの湾曲の曲率である半径Ｒ１および他側部２２における側面２２ａの湾曲の曲率である半径Ｒ２を互いに同じ値に設定したが、室内空間の形状や当該室内ユニットの配置位置などに応じて互いに異なる値に設定してもよい。 [Modification example]
In the above embodiment, the radius R1 which is the curvature of the curvature of the side surface 21a on the one side portion 21 and the radius R2 which is the curvature of the curvature of the side surface 22a on the other side portion 22 are set to the same value. The values may be set differently from each other depending on the arrangement position of the indoor unit and the like.
　上記実施形態では、一側部２１における側面２１ｂが壁面１に接する角度である鋭角Ｑ１および他側部２２における側面２２ｂが壁面１に接する角度である鋭角Ｑ２を互いに同じ値に設定したが、室内空間の形状や当該室内ユニットの配置位置などに応じて互いに異なる値に設定してもよい。だだし、このような変形例では、室内ユニットの外観が左右非対称の形状となる。 In the above embodiment, the acute angle Q1 at which the side surface 21b on the one side portion 21 is in contact with the wall surface 1 and the acute angle Q2 at which the side surface 22b on the other side portion 22 is in contact with the wall surface 1 are set to the same values. The values may be set differently from each other depending on the shape of the space and the arrangement position of the indoor unit. However, in such a modified example, the appearance of the indoor unit is asymmetrical.
　また、以上の実施形態においては、ファブリック部材５０に取付けた面ファスナー６１をループ型とし、前面パネル３０に取付けた面ファスナー６２をフック型としたが、面ファスナーの形状を逆にしてもよい。逆にした場合、ファブリック部材５０を装着していない前面パネル３０が副本体２０に取付けられた際に弾性部材７０に当接するのが前面パネル３０に取付けられたループ型の面ファスナーとなり、弾性部材７０への当たりが弱くなり、弾性部材７０の耐久性を向上できる。 Further, in the above embodiment, the surface fastener 61 attached to the fabric member 50 is a loop type, and the surface fastener 62 attached to the front panel 30 is a hook type, but the shape of the surface fastener may be reversed. When the case is reversed, when the front panel 30 to which the fabric member 50 is not attached is attached to the sub-main body 20, it is the loop type hook-and-loop fastener attached to the front panel 30 that comes into contact with the elastic member 70, and the elastic member. The contact with the 70 is weakened, and the durability of the elastic member 70 can be improved.
　その他、上記各実施形態および変形例は、例として提示したものであり、発明の範囲を限定することは意図していない。この新規な実施形態および変形例は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、書き換え、変更を行うことができる。これら実施形態や変形は、発明の範囲は要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 In addition, each of the above embodiments and modifications is presented as an example, and is not intended to limit the scope of the invention.
