The design cover 3 includes an upper design cover 3a and a lower design cover 3b.
　筐体１の上部（本例では天面）には、室内空気を内部に吸い込む上部吸込口４が形成されている。筐体１の下部には、空調空気を外部に吹き出す吹出口５が形成されている。 An upper suction port 4 for sucking indoor air into the interior is formed in the upper portion of the housing 1 (the top surface in this example). A blower outlet 5 for blowing conditioned air to the outside is formed in the lower part of the housing 1.
　図３及び図４に示すように、筐体１内には、上部吸込口４及び前面吸込口１２から吹出口５に向かう空気の流れを生じさせる送風ファン６と、送風ファン６を上方から覆うように配置され、冷媒と室内空気との熱交換を行うことで空調空気を作り出す熱交換器７と、が収納されている。そして、これらの構成要素により、室内機本体１００内には、上部吸込口４及び前面吸込口１２から熱交換器７と送風ファン６とを経て吹出口５に至る空気流路が形成されている。室内機本体１００内にはさらに、回路基板などを収容する電気品箱（図示せず）と、熱交換器７の下端部の下方に設けられ、熱交換器７の結露水を受けるドレンパン８と、が設けられている。 As shown in FIGS. 3 and 4, in the housing 1, a blower fan 6 that causes an air flow from the upper suction port 4 and the front suction port 12 toward the blower outlet 5 and the blower fan 6 are covered from above. And a heat exchanger 7 that creates conditioned air by performing heat exchange between the refrigerant and room air. And by these components, the air flow path from the upper inlet 4 and the front inlet 12 to the outlet 5 through the heat exchanger 7 and the blower fan 6 is formed in the indoor unit main body 100. . The indoor unit main body 100 further includes an electrical component box (not shown) that accommodates a circuit board and the like, a drain pan 8 that is provided below the lower end of the heat exchanger 7 and receives the dew condensation water of the heat exchanger 7. , Is provided.
　送風ファン６は、例えばクロスフローファンであり、熱交換器７は、例えばフィンチューブ型熱交換器であるが、それらに限定されない。また、本例の熱交換器７は、空気の流れにおいて送風ファン６の上流側に配置されているが、熱交換器７は送風ファン６の下流側に配置されていてもよい。 The blower fan 6 is a cross flow fan, for example, and the heat exchanger 7 is a fin tube type heat exchanger, for example, but is not limited thereto. Moreover, although the heat exchanger 7 of this example is arrange | positioned in the upstream of the ventilation fan 6 in the flow of air, the heat exchanger 7 may be arrange | positioned in the downstream of the ventilation fan 6. FIG.
　上部吸込口４及び前面吸込口１２と熱交換器７との間には、吸い込まれた室内空気に含まれる塵埃などを取り除くためのフィルター９が設けられている。吹出口５には、気流の吹出し方向を上下方向で調整する上下風向調整板１０が設けられている。 Between the upper suction port 4 and the front suction port 12 and the heat exchanger 7, a filter 9 for removing dust contained in the sucked indoor air is provided. The blower outlet 5 is provided with an up / down air direction adjusting plate 10 that adjusts the blowing direction of the airflow in the up / down direction.
　次に、室内機本体１００内における空気の流れについて簡単に説明する。
　まず、室内空気は、送風ファン６によって室内機本体１００の上部吸込口４及び前面吸込口１２から室内機本体１００内に流れ込む。このとき、フィルター９によって空気に含まれている塵埃などが除去される。この室内空気は、熱交換器７を通過する際に、熱交換器７の内部を流通する冷媒との熱交換により加熱又は冷却されて空調空気となる。そして、空調空気は、上下風向調整板１０により調整された風向に沿って、吹出口５から室内機本体１００の外部、つまり空調対象域に吹き出されるようになっている。 Next, the flow of air in the indoor unit body 100 will be briefly described.
First, the room air flows into the indoor unit body 100 from the upper suction port 4 and the front suction port 12 of the indoor unit body 100 by the blower fan 6. At this time, dust and the like contained in the air are removed by the filter 9. When this indoor air passes through the heat exchanger 7, it is heated or cooled by heat exchange with the refrigerant flowing through the inside of the heat exchanger 7 to become conditioned air. The conditioned air is blown out from the outlet 5 to the outside of the indoor unit body 100, that is, to the air-conditioning target area, along the air direction adjusted by the up / down air direction adjusting plate 10.
　図５は、本実施の形態に係る空気調和機の室内機の前面パネル２の斜視図である。図５では、前面パネル２の全体の斜視図と、前面パネル２の右端部を拡大した斜視図とを併せて示している。図６及び図７は、本実施の形態に係る空気調和機の室内機の前面パネル２及び意匠カバー３の斜視図である。図６は、意匠カバー３を前面パネル２に取り付ける前の状態を示しており、図７は、意匠カバー３を前面パネル２に取り付けた後の状態を示している。 FIG. 5 is a perspective view of the front panel 2 of the indoor unit of the air conditioner according to the present embodiment. In FIG. 5, the perspective view of the whole front panel 2 and the perspective view which expanded the right end part of the front panel 2 are shown collectively. 6 and 7 are perspective views of the front panel 2 and the design cover 3 of the indoor unit of the air conditioner according to the present embodiment. FIG. 6 shows a state before the design cover 3 is attached to the front panel 2, and FIG. 7 shows a state after the design cover 3 is attached to the front panel 2.
　図５に示すように、前面パネル２は、意匠性を向上させるため前面の全体においてフラットな面形状を有している。また、前面パネル２は矩形状を有している。室内機本体１００が壁面に取り付けられた状態において、前面パネル２の長手方向が左右方向、つまり水平方向となり、前面パネル２の短手方向が上下方向、つまり鉛直方向となる。また、正面視において前面パネル２の上下方向の中央に、左端部の内側から右端部の内側まで水平に延びる凹部１１が形成されている。そのため、前面パネル２は、図３に示すように、上下方向の中央で前面側から背面側に向かって凹んでいる。 As shown in FIG. 5, the front panel 2 has a flat surface shape on the entire front surface in order to improve the design. The front panel 2 has a rectangular shape. In a state where the indoor unit main body 100 is attached to the wall surface, the longitudinal direction of the front panel 2 is the left-right direction, that is, the horizontal direction, and the short direction of the front panel 2 is the vertical direction, that is, the vertical direction. In addition, a concave portion 11 that extends horizontally from the inside of the left end portion to the inside of the right end portion is formed in the center of the front panel 2 in the vertical direction when viewed from the front. Therefore, as shown in FIG. 3, the front panel 2 is recessed from the front side to the back side at the center in the vertical direction.
　ただし、図５に示すように、前面パネル２の前面の上下方向の中央において、凹部１１よりも左側、つまり、凹部１１の左端部から前面パネル２の左端部までの部分（以下、左側の凹側部２ａと称する）は、フラットであり、かつ、左側の凹側部２ａの上下のフラットな面と同一平面上にある。また、前面パネル２の前面の上下方向の中央において、凹部１１よりも右側、つまり、凹部１１の右端部から前面パネル２の右端部までの部分（以下、右側の凹側部２ａと称する）は、フラットであり、かつ、右側の凹側部２ａの上下のフラットな面と同一平面上にある。また、凹部１１は、前面パネル２の前面側が凹状となり、前面パネル２の背面側が凸状となるように凹んでいる。凹部１１のうちの下面には、前面吸込口１２が形成されている。なお、凹部１１が形成されている位置は、厳密に前面パネル２の上下方向の中央でなくてもよい。 However, as shown in FIG. 5, at the center of the front surface of the front panel 2 in the vertical direction, the left side of the recess 11, that is, the portion from the left end of the recess 11 to the left end of the front panel 2 (hereinafter, left recess The side portion 2a is flat and is flush with the upper and lower flat surfaces of the left concave side portion 2a. Further, in the center of the front surface of the front panel 2 in the vertical direction, a portion on the right side of the concave portion 11, that is, a portion from the right end portion of the concave portion 11 to the right end portion of the front panel 2 (hereinafter referred to as right concave side portion 2 a). The flat surface is flush with the upper and lower flat surfaces of the right concave side portion 2a. Moreover, the recessed part 11 is dented so that the front side of the front panel 2 may become concave, and the back side of the front panel 2 may become convex. A front suction port 12 is formed on the lower surface of the recess 11. Note that the position where the recess 11 is formed may not strictly be the center in the vertical direction of the front panel 2.
　図６及び図７に示すように、意匠カバー３は、例えば透明樹脂で形成されており、前面パネル２と同様に前面の全体においてフラットな面形状を有している。また、意匠カバー３は矩形状を有している。室内機本体１００が壁面に取り付けられた状態において、意匠カバー３の長手方向が左右方向、つまり水平方向となり、意匠カバー３の短手方向が上下方向、つまり鉛直方向となる。また、意匠カバー３は、４辺の縁部の一部又は全部に、背面側に突出した図示省略の周壁部が設けられている。意匠カバー３は、それら周壁部の一部又は全部に設けられた図示省略の爪により、前面パネル２に取り付けられる。なお、意匠カバー３を前面パネル２に取り付ける方法は爪に限定されず、例えば、接着剤などを用いて取り付けてもよい。 As shown in FIGS. 6 and 7, the design cover 3 is formed of, for example, a transparent resin, and has a flat surface shape on the entire front surface in the same manner as the front panel 2. The design cover 3 has a rectangular shape. In a state where the indoor unit main body 100 is attached to the wall surface, the longitudinal direction of the design cover 3 is the left-right direction, that is, the horizontal direction, and the short direction of the design cover 3 is the vertical direction, that is, the vertical direction. In addition, the design cover 3 is provided with a peripheral wall portion (not shown) that protrudes on the back side on a part or all of the edges of the four sides. The design cover 3 is attached to the front panel 2 by a claw (not shown) provided on a part or all of the peripheral wall portions. In addition, the method of attaching the design cover 3 to the front panel 2 is not limited to a nail, For example, you may attach using an adhesive agent.
　また、図６及び図７に示すように、上意匠カバー３ａは、前面パネル２の凹部１１の上側に、凹部１１の上端部から前面パネル２の上端部にかけて、前面パネル２の左端部から右端部までを覆うように取り付けられる。また、下意匠カバー３ｂは、前面パネル２の凹部１１の下側に、凹部１１の下端部から前面パネル２の下端部にかけて、前面パネル２の左端部から右端部までを覆うように取り付けられる。そして、このように意匠カバー３を前面パネル２の前面側に取り付けることで、室内機本体１００を正面から見たときの意匠性を向上させている。 As shown in FIGS. 6 and 7, the upper design cover 3 a is located above the recess 11 of the front panel 2, from the upper end of the recess 11 to the upper end of the front panel 2, and from the left end to the right end of the front panel 2. It is attached to cover up to the part. The lower design cover 3 b is attached to the lower side of the recess 11 of the front panel 2 so as to cover from the lower end of the recess 11 to the lower end of the front panel 2 from the left end to the right end of the front panel 2. And the design property when the indoor unit main body 100 is seen from the front is improved by attaching the design cover 3 to the front side of the front panel 2 in this way.
　また、意匠カバー３が前面パネル２の前面側に取り付けられた状態において、図３及び図４に示すように意匠カバー３は、前面パネル２の凹部１１、及び左右の凹側部２ａよりも、前面側に突出している。そのため、上意匠カバー３ａと下意匠カバー３ｂとの隙間に影が形成される。そして、その影は前面パネル２の左右端部まで延びて形成されるため、凹部１１が前面パネル２の左右端部まで延びて形成されていなくても、影によって前面パネル２を上下に分断させる視覚的効果が得られるため、シャープでスッキリとした印象を与え、意匠性を向上させることができる。 Moreover, in the state in which the design cover 3 is attached to the front side of the front panel 2, as shown in FIGS. 3 and 4, the design cover 3 is more than the concave portion 11 of the front panel 2 and the left and right concave side portions 2a. Projects to the front side. Therefore, a shadow is formed in the gap between the upper design cover 3a and the lower design cover 3b. Since the shadow is formed to extend to the left and right ends of the front panel 2, even if the recess 11 is not formed to extend to the left and right ends of the front panel 2, the front panel 2 is divided up and down by the shadow. Since a visual effect is obtained, it is possible to give a sharp and refreshing impression and improve the design.
　また、意匠カバー３は、前面パネル２に取り付けられた際、前面パネル２の左右端部からはみ出す大きさに設けられている。そのため、室内機本体１００の側面も上下に分断するような構成とした場合に、前面側と統一感のあるデザインとすることができる。 The design cover 3 is provided in a size that protrudes from the left and right ends of the front panel 2 when attached to the front panel 2. For this reason, when the side surface of the indoor unit main body 100 is also divided into upper and lower parts, it is possible to achieve a design that is consistent with the front side.
　なお、前面パネル２の色と意匠カバー３の色とは、例えば、白色同士など同色でもよいが、例えば、前面パネル２を黒色、意匠カバー３を赤色とするなど、前面パネル２の色と意匠カバー３の色とを異ならせることで、前面パネル２の凹部１１の色を強調させることができるため、意匠性をさらに向上させることができる。 The color of the front panel 2 and the color of the design cover 3 may be the same color such as white, for example, but the color of the front panel 2 and the design, for example, the front panel 2 is black and the design cover 3 is red. Since the color of the concave portion 11 of the front panel 2 can be emphasized by making the color of the cover 3 different, the design can be further improved.
　また、前面パネル２は、凹部１１が左右端部まで延びて形成されておらず、左側の凹側部２ａは、フラットであり、かつ、左側の凹側部２ａの上下のフラットな面と同一平面上である。さらに、右側の凹側部２ａは、フラットであり、かつ、右側の凹側部２ａの上下のフラットな面と同一平面上である。そのため、前面パネル２の強度を確保することができ、凹側部２ａに凹形状が形成されている場合に比べ変形及び破損を抑制できる。 Further, the front panel 2 is not formed with the concave portion 11 extending to the left and right end portions, the left concave side portion 2a is flat, and is the same as the upper and lower flat surfaces of the left concave side portion 2a. On the plane. Furthermore, the right concave side 2a is flat and flush with the upper and lower flat surfaces of the right concave side 2a. Therefore, the strength of the front panel 2 can be ensured, and deformation and breakage can be suppressed as compared with the case where the concave shape is formed on the concave side portion 2a.
　また、上意匠カバー３ａと下意匠カバー３ｂとを同形状の共通部品とすることで、部品を成型する際の金型にかかるコスト及び部品管理コストを低減することができるため、製造コストを低減することができる。 Moreover, since the upper design cover 3a and the lower design cover 3b are common parts having the same shape, it is possible to reduce the cost of the mold and the part management cost when molding the parts, thereby reducing the manufacturing cost. can do.
　また、意匠カバー３を透明部品とすることで、光が反射しやすくなるため、意匠性を向上させることができる。 Moreover, since the design cover 3 is made of a transparent part, the light can be easily reflected, so that the design can be improved.
　また、透明部品でできた意匠カバー３を背面側から塗装することで、塗装面が傷ついたり剥がれたりするのを防ぐことができる。さらに、前面パネル２に取り付けた際に、意匠カバー３と前面パネル２との間に挟まれた埃、及び、取り付け形状を隠ぺいすることができるため、意匠性を向上させることができる。 Also, by painting the design cover 3 made of transparent parts from the back side, the painted surface can be prevented from being damaged or peeled off. Furthermore, when it is attached to the front panel 2, the dust sandwiched between the design cover 3 and the front panel 2 and the attachment shape can be concealed, so that the design can be improved.
　なお、本実施の形態では、意匠カバー３は、１つの上意匠カバー３ａと１つの下意匠カバー３ｂとで構成されているとしたが、それに限定されず、上意匠カバー３ａを例えば２つなど複数に分割して構成してもよいし、下意匠カバー３ｂも同様に、例えば２つなど複数に分割して構成してもよい。 In the present embodiment, the design cover 3 is composed of one upper design cover 3a and one lower design cover 3b. However, the present invention is not limited to this. For example, two upper design covers 3a are provided. The lower design cover 3b may be similarly divided into a plurality of parts such as two, for example.

The shaft portion 14 is provided on the rotation axis R and is supported by the arm portion 13 with respect to the front panel 2. The arm portion 13 and the shaft portion 14 are formed integrally with the front panel 2 as a part of the front panel 2.
　図１０は、本実施の形態に係る空気調和機の室内機における前面パネル２及び回転部材２０を背面側から見た構成を示す分解斜視図である。図１０に示すように、回転部材２０は、Ｌ字状に屈曲した本体部２１と、本体部２１の一端に設けられた筒状の軸受部２２と、本体部２１の他端に設けられたアーム保持部２３と、を有している。軸受部２２は、前面パネル２に設けられた軸部１４の全周を囲み、軸部１４を回転自在に支持するようになっている。本例の回転部材２０は、前面パネル２の軸部１４を支持する軸受部２２を有しているため、軸受部材として機能する。アーム保持部２３は、本体部２１から突出して形成された一対の保持片２３ａ、２３ｂを備えている。アーム保持部２３は、前面パネル２に設けられたアーム部１３を保持片２３ａ、２３ｂで両側から抱えて保持するようになっている。また、アーム保持部２３は、アーム部１３を保持した状態でアーム部１３の一部に係止されるようになっている。 FIG. 10 is an exploded perspective view showing the configuration of the front panel 2 and the rotating member 20 in the indoor unit of the air conditioner according to the present embodiment as viewed from the back side. As shown in FIG. 10, the rotating member 20 is provided at a body portion 21 bent in an L shape, a cylindrical bearing portion 22 provided at one end of the body portion 21, and the other end of the body portion 21. Arm holding portion 23. The bearing portion 22 surrounds the entire circumference of the shaft portion 14 provided on the front panel 2 and supports the shaft portion 14 rotatably. Since the rotation member 20 of this example has the bearing part 22 which supports the axial part 14 of the front panel 2, it functions as a bearing member. The arm holding part 23 includes a pair of holding pieces 23 a and 23 b formed so as to protrude from the main body part 21. The arm holding part 23 is configured to hold the arm part 13 provided on the front panel 2 by holding pieces 23a and 23b from both sides. Further, the arm holding portion 23 is locked to a part of the arm portion 13 in a state where the arm portion 13 is held.
　また、回転部材２０は、後述する収納凹部３０に収納された状態で筐体１に係止されるように、上部係止部２４（図１２参照）及び下部係止部２５を有している。上部係止部２４は、本体部２１の上記一端側に、軸受部２２と軸方向に隣接して設けられている。下部係止部２５は、本体部２１の上記他端側に設けられている。下部係止部２５は、本体部２１から保持片２３ａ、２３ｂの突出方向とは逆方向に突出してＵ字状に曲がった形状を有する係止片２５ａと、係止片２５ａの先端に設けられた係止端面２５ｂと、を有している。係止片２５ａには、保持片２３ａ、２３ｂの突出方向とは逆方向を向いた凸面２５ａ１と、保持片２３ａ、２３ｂの突出方向を向いた凹面２５ａ２と、が形成されている。 Further, the rotating member 20 has an upper locking portion 24 (see FIG. 12) and a lower locking portion 25 so as to be locked to the housing 1 in a state of being stored in a storage recess 30 described later. . The upper locking portion 24 is provided on the one end side of the main body portion 21 so as to be adjacent to the bearing portion 22 in the axial direction.

　図１１及び図１２は、本実施の形態に係る空気調和機の室内機において回転部材２０を前面パネル２に取り付ける取付手順を示す斜視図である。回転部材２０を前面パネル２に取り付ける際には、まず図１１に示すように、回転軸Ｒ方向でアーム保持部２３とアーム部１３とが干渉しないような相対角度で、前面パネル２の軸部１４を回転部材２０の軸受部２２に挿入する。これにより、回転部材２０は、前面パネル２に対し、回転軸Ｒを中心として回転自在に取り付けられる。 FIG.11 and FIG.12 is a perspective view which shows the attachment procedure which attaches the rotation member 20 to the front panel 2 in the indoor unit of the air conditioner which concerns on this Embodiment. When attaching the rotating member 20 to the front panel 2, first, as shown in FIG. 11, the shaft portion of the front panel 2 is arranged at a relative angle so that the arm holding portion 23 and the arm portion 13 do not interfere with each other in the direction of the rotation axis R. 14 is inserted into the bearing portion 22 of the rotating member 20. Thereby, the rotation member 20 is attached to the front panel 2 so as to be rotatable about the rotation axis R.
　次に、図１１中の太矢印で示す回転方向に回転部材２０を回転させ、図１２に示すように、回転部材２０のアーム保持部２３に前面パネル２のアーム部１３を保持させる。アーム保持部２３がアーム部１３を保持した状態では、アーム保持部２３はアーム部１３の一部に係止される。アーム保持部２３が係止されることにより、回転部材２０の回転は、回転部材２０の自重のみによっては回転部材２０が回転しない程度の弱い力で規制される。これにより、回転部材２０は、前面パネル２に仮保持される。 Next, the rotating member 20 is rotated in the rotation direction indicated by the thick arrow in FIG. 11, and the arm portion 13 of the front panel 2 is held by the arm holding portion 23 of the rotating member 20 as shown in FIG. In a state where the arm holding part 23 holds the arm part 13, the arm holding part 23 is locked to a part of the arm part 13. When the arm holding portion 23 is locked, the rotation of the rotating member 20 is restricted by a weak force that does not rotate the rotating member 20 only by its own weight. Thereby, the rotating member 20 is temporarily held by the front panel 2.
　回転部材２０が前面パネル２に仮保持された状態では、上部係止部２４と下部係止部２５の係止端面２５ｂとがいずれも前面側を向くように配置される。また、この状態では、下部係止部２５の係止片２５ａは、背面側及び下側に凸となる。さらに、この状態では、アーム部１３に設けられた突起部１３ａが、係止片２５ａの凹面２５ａ２の一部に当接するようになっている。 In the state where the rotating member 20 is temporarily held on the front panel 2, the upper locking portion 24 and the locking end surface 25b of the lower locking portion 25 are both arranged to face the front side. In this state, the locking piece 25a of the lower locking portion 25 is convex on the back side and the lower side. Further, in this state, the protruding portion 13a provided on the arm portion 13 comes into contact with a part of the concave surface 25a2 of the locking piece 25a.
　図１３は、本実施の形態に係る空気調和機の室内機において回転部材２０が前面パネル２に取り付けられた状態を示す部分断面図である。図１３は、回転部材２０及び前面パネル２を上方から見た上面図において、軸部１４、アーム部１３及び軸受部２２については回転軸Ｒに沿った断面を示したものである。 FIG. 13 is a partial cross-sectional view showing a state where the rotating member 20 is attached to the front panel 2 in the indoor unit of the air conditioner according to the present embodiment. FIG. 13 is a top view of the rotating member 20 and the front panel 2 as viewed from above, and shows a cross section along the rotation axis R of the shaft portion 14, the arm portion 13, and the bearing portion 22.
　図１３に示すように、回転部材２０は、軸部１４から軸受部２２が抜けるのを防止する軸抜け防止部２６を有している。軸抜け防止部２６は、回転軸Ｒ方向において軸受部２２から離れた位置又は軸受部２２と隣接した位置に設けられている。回転部材２０が前面パネル２に取り付けられた状態では、軸抜け防止部２６は、回転軸Ｒ方向において軸受部２２よりもアーム部１３側（図中の左側）に設けられている。軸抜け防止部２６は、回転軸Ｒに平行に見たとき、軸部１４又はアーム部１３の一部と重なるように設けられている。本例の軸抜け防止部２６は、軸部１４に対しては重なり幅Ｗ１で重なっており、アーム部１３に対しては重なり幅Ｗ２で重なっている。回転部材２０の軸受部２２が前面パネル２の軸部１４に取り付けられる際には、軸抜け防止部２６は、軸部１４及びアーム部１３を乗り越えるようになっている。回転部材２０が前面パネル２に取り付けられた状態で、軸受部２２が軸部１４から抜ける方向に移動したときには、軸抜け防止部２６が軸部１４又はアーム部１３に当接し、それ以上の軸受部２２の移動が規制される。これにより、軸受部２２が軸部１４から抜けるのを防止できるため、前面パネル２から回転部材２０が脱落してしまうのを防ぐことができる。 As shown in FIG. 13, the rotating member 20 has a shaft dropout prevention portion 26 that prevents the bearing portion 22 from coming off from the shaft portion 14. The shaft dropout prevention portion 26 is provided at a position away from the bearing portion 22 in the rotation axis R direction or a position adjacent to the bearing portion 22. In a state where the rotary member 20 is attached to the front panel 2, the shaft dropout prevention portion 26 is provided on the arm portion 13 side (left side in the drawing) with respect to the bearing portion 22 in the direction of the rotation axis R. The shaft dropout prevention portion 26 is provided so as to overlap a part of the shaft portion 14 or the arm portion 13 when viewed in parallel to the rotation axis R. The shaft dropout prevention portion 26 of this example overlaps the shaft portion 14 with an overlap width W1, and overlaps the arm portion 13 with an overlap width W2. When the bearing portion 22 of the rotating member 20 is attached to the shaft portion 14 of the front panel 2, the shaft dropout prevention portion 26 gets over the shaft portion 14 and the arm portion 13. When the rotary member 20 is attached to the front panel 2 and the bearing portion 22 moves in a direction to come off from the shaft portion 14, the shaft dropout prevention portion 26 comes into contact with the shaft portion 14 or the arm portion 13, and more bearings are provided. The movement of the part 22 is restricted. Thereby, since it can prevent that the bearing part 22 comes off from the axial part 14, it can prevent that the rotating member 20 falls off from the front panel 2. FIG.
　次に、回転部材２０が取り付けられた前面パネル２を筐体１に取り付けるための取付構造及び取付手順について説明する。 Next, an attachment structure and attachment procedure for attaching the front panel 2 to which the rotating member 20 is attached to the housing 1 will be described.

FIG. 15 is a schematic side view showing a configuration in which the upper part of the housing 1 in the indoor unit of the air conditioner according to the present embodiment is viewed from the right side. As shown in FIGS. 14 and 15, a storage recess 30 that stores the rotating member 20 is formed in a concave shape with respect to the front surface 1 a in the upper right portion of the front surface 1 a of the housing 1. On the back side of the storage recess 30, there is formed a concave wall 35 that has a shape mainly along the main body 21 of the rotation member 20 and also functions as a guide surface that guides the rotation member 20 to the storage position. A tool insertion hole 33 into which a rod-shaped tool is inserted when the rotary member 20 is removed from the storage recess 30 is formed below the storage recess 30 in the front surface 1 a of the housing 1. The tool insertion hole 33 extends obliquely upward along the concave wall 35 from the open end formed in the front surface 1 a of the housing 1. In addition, although the storage recessed part 30 and the tool insertion hole 33 are formed also in the upper left part of the front surface 1a of the housing | casing 1, illustration and description are abbreviate | omitted about the storage recessed part 30 and the tool insertion hole 33 of the left side.
　収納凹部３０内には、回転部材２０の上部係止部２４を係止する係止部３１（図１５参照）と、下部係止部２５の係止端面２５ｂを係止する係止部３２と、が形成されている。凹壁３５のうち係止部３２と隣接した部分には、収納凹部３０と工具挿入穴３３との間を貫通する貫通孔３４が形成されている。貫通孔３４には、下部係止部２５の係止片２５ａが収納凹部３０側から嵌め込まれるようになっている。 In the storage recess 30, a locking portion 31 (see FIG. 15) that locks the upper locking portion 24 of the rotating member 20, and a locking portion 32 that locks the locking end surface 25 b of the lower locking portion 25. , Is formed. A through hole 34 penetrating between the storage recess 30 and the tool insertion hole 33 is formed in a portion of the concave wall 35 adjacent to the locking portion 32. A locking piece 25a of the lower locking portion 25 is fitted into the through-hole 34 from the storage recess 30 side.
　図１６～図１８は、本実施の形態に係る空気調和機の室内機において前面パネル２を筐体１に取り付ける取付手順を示す断面図である。本例では、筐体１は既に室内の壁面に取り付けられているものとする。前面パネル２を筐体１に取り付ける際には、まず図１６に示すように、前面パネル２を筐体１の前面に近づけ、前面パネル２に仮保持された回転部材２０を収納凹部３０内に挿入する。 16 to 18 are cross-sectional views showing an attachment procedure for attaching the front panel 2 to the casing 1 in the indoor unit of the air conditioner according to the present embodiment. In this example, it is assumed that the housing 1 is already attached to the wall surface in the room. When attaching the front panel 2 to the housing 1, first, as shown in FIG. 16, the front panel 2 is brought close to the front surface of the housing 1, and the rotating member 20 temporarily held by the front panel 2 is placed in the housing recess 30. insert.
　次に、図１７に示すように、前面パネル２を斜め上方に持ち上げ、回転部材２０の上部係止部２４を収納凹部３０内の係止部３１に係止させる。 Next, as shown in FIG. 17, the front panel 2 is lifted obliquely upward, and the upper locking portion 24 of the rotating member 20 is locked to the locking portion 31 in the housing recess 30.
　次に、係止部３１に係止された上部係止部２４を支点として、前面パネル２を図１７中の反時計回り方向に回転させ、回転部材２０を収納凹部３０内に押し込む。これにより、図１８に示すように、回転部材２０の係止端面２５ｂが収納凹部３０内の係止部３２に係止される。このとき、係止片２５ａは、アーム部１３に設けられた突起部１３ａによって押し込まれて貫通孔３４に嵌り込む。これにより、係止片２５ａの凸面２５ａ１は、工具挿入穴３３側に突き出た状態になる。以上の手順により、回転部材２０が筐体１の収納凹部３０に取り付けられるとともに、前面パネル２が回転部材２０を介して筐体１に回転自在に取り付けられる。 Next, with the upper locking portion 24 locked to the locking portion 31 as a fulcrum, the front panel 2 is rotated counterclockwise in FIG. 17 and the rotating member 20 is pushed into the storage recess 30. As a result, as shown in FIG. 18, the locking end surface 25 b of the rotating member 20 is locked to the locking portion 32 in the storage recess 30. At this time, the locking piece 25 a is pushed in by the protrusion 13 a provided on the arm portion 13 and fits into the through hole 34. As a result, the convex surface 25a1 of the locking piece 25a protrudes toward the tool insertion hole 33 side. Through the above procedure, the rotating member 20 is attached to the housing recess 30 of the housing 1, and the front panel 2 is rotatably attached to the housing 1 via the rotating member 20.
　筐体１に取り付けられた前面パネル２は、軸部１４（すなわち、回転軸Ｒ）を中心として筐体１の前面側を容易に開閉可能となる。したがって、ユーザーは、前面パネル２を開けることによって、フィルター９の取付け及び取外しを容易に行うことができる。ただし、前面パネル２の軸部１４の全周が回転部材２０の軸受部２２によって囲まれており、かつ回転部材２０が筐体１に固定して取り付けられているため、ユーザーは、前面パネル２自体を筐体１から容易に取り外すことはできない。 The front panel 2 attached to the housing 1 can easily open and close the front surface side of the housing 1 around the shaft portion 14 (that is, the rotation axis R). Therefore, the user can easily attach and remove the filter 9 by opening the front panel 2. However, since the entire circumference of the shaft portion 14 of the front panel 2 is surrounded by the bearing portion 22 of the rotating member 20 and the rotating member 20 is fixedly attached to the housing 1, the user can It cannot be easily removed from the housing 1.
　次に、前面パネル２を筐体１から取り外す手順について説明する。 Next, the procedure for removing the front panel 2 from the housing 1 will be described.

FIG. 20 is a cross-sectional view showing a procedure for removing front panel 2 from housing 1 in the indoor unit of the air conditioner according to the present embodiment. When removing the front panel 2 from the housing 1, first, as shown in FIG. 19, the front panel 2 is opened to expose the front surface 1 a of the housing 1.
　次に、図２０に示すように、工具挿入穴３３に棒状の工具１１０（例えば、プラスドライバー等）を差し込み、工具１１０を係止片２５ａの凸面２５ａ１に接触させる。そして、工具１１０によって係止片２５ａを上方向に押し上げる。これにより、係止部３２による係止端面２５ｂの係止が外れ、図１７に示したような状態になる。その後、前面パネル２を斜め下方に引き下げることによって、係止部３１による上部係止部２４の係止が外れる。以上の手順により、回転部材２０が筐体１の収納凹部３０から取り外されるとともに、前面パネル２及び回転部材２０が筐体１から取り外される。すなわち、前面パネル２は、ユーザーによって筐体１から容易に取り外すことはできないが、メンテナンス作業者等によるメンテナンス時には、工具１１０を用いて筐体１から容易に取り外すことができるようになっている。 Next, as shown in FIG. 20, a rod-shaped tool 110 (for example, a Phillips screwdriver) is inserted into the tool insertion hole 33, and the tool 110 is brought into contact with the convex surface 25a1 of the locking piece 25a. Then, the locking piece 25a is pushed upward by the tool 110. Thereby, the locking of the locking end surface 25b by the locking part 32 is released, and the state shown in FIG. 17 is obtained. Thereafter, the front panel 2 is pulled down obliquely, whereby the locking of the upper locking portion 24 by the locking portion 31 is released. With the above procedure, the rotating member 20 is removed from the housing recess 30 of the housing 1, and the front panel 2 and the rotating member 20 are removed from the housing 1. That is, the front panel 2 cannot be easily removed from the housing 1 by the user, but can be easily removed from the housing 1 using the tool 110 during maintenance by a maintenance worker or the like.
　前面パネル２及び回転部材２０が一体となって筐体１から取り外される点は、本実施の形態に係る空気調和機の室内機の特徴の一つである。ここで、回転部材２０には軸抜け防止部２６が設けられているため、前面パネル２及び回転部材２０が筐体１から取り外された際に、回転部材２０が前面パネル２から脱落してしまうことを防止できる。 The point that the front panel 2 and the rotating member 20 are integrally removed from the housing 1 is one of the features of the indoor unit of the air conditioner according to the present embodiment. Here, since the rotation member 20 is provided with the shaft dropout prevention portion 26, the rotation member 20 falls off the front panel 2 when the front panel 2 and the rotation member 20 are removed from the housing 1. Can be prevented.
　以上説明したように、本実施の形態に係る空気調和機の室内機は、筐体１と、筐体１の前面側に設けられる前面パネル２と、前面パネル２の左右方向に沿った回転軸Ｒを中心として前面パネル２に対して回転自在となるように前面パネル２の上部に取り付けられるとともに、筐体１の上部に取り付けられる回転部材２０と、を備え、前面パネル２又は回転部材２０の一方（本例では、前面パネル２）は、回転軸Ｒ上に設けられる軸部１４を有しており、前面パネル２又は回転部材２０の他方（本例では、回転部材２０）は、軸部１４の全周を囲んで軸部１４を回転自在に支持する軸受部２２を有しているものである。 As described above, the indoor unit of the air conditioner according to the present embodiment includes the housing 1, the front panel 2 provided on the front surface side of the housing 1, and the rotation axis along the left-right direction of the front panel 2. A rotating member 20 that is attached to the upper portion of the front panel 2 so as to be rotatable with respect to the front panel 2 around R, and is attached to the upper portion of the housing 1. One (in this example, the front panel 2) has a shaft portion 14 provided on the rotation axis R, and the other of the front panel 2 or the rotation member 20 (in this example, the rotation member 20) is a shaft portion. 14 has a bearing portion 22 that surrounds the entire circumference of the shaft 14 and rotatably supports the shaft portion 14.
