For example, if the internal overhanging space 33 at the top of the main body 2 has a margin, the shape of the upper surface of FIG. 23 (a) is smaller than the shape of the lower surface of FIG. 23 (b). It is also possible to take such a configuration. By wrapping functional parts such as the stepping motor 25 provided in the internal overhanging space 33 with a soft curve in a side outline such as the lid member 30 while eliminating unnecessary internal space, the feeling of pressure given to the occupant is reduced. can do.
- the lid member 30 is provided with a latching claw 35 on the back side.
- the lid member 30 can be easily attached to the casing 6 by inserting the latching claw 35 into a predetermined hole of the casing 6, inserting the screw 31 into the hole 36 and screwing it into the screw hole of the casing 6.
- a rib 37 is formed on the back side of the lid member 30 to reinforce the lid member 30.
- the cover member 30 which can remove the side surface 2S of the main body 2.
- the side surface 2S of the main body 2 may not be removable.
- the side surface 2S of the main body 2 may be configured by the casing 6.
- the convenience of maintenance is reduced, but the maintenance is easier than in the prior art, and the attachment work is easier than in the past.
- the casing is removed, the parts that are dense on the side surface spread in a flat shape, whereas if the side surface shape that protrudes as in the above embodiment is provided, the parts that are densely matched to the protruding side surface shape are obtained. spread.
- the densely shaped parts become three-dimensional along the side surface shape, so that a portion where tools and human hands can easily enter can be formed. As a result, the efficiency of the installation work, and hence the maintenance work, is improved.
- the internal overhang space 33 is formed across the entire height direction so as to reach the upper surface 2U from the lower surface 2D in the height direction of the main body 2.
- the same effect may be obtained even if it is not formed over the entire height direction of the internal overhang space 33.
- the side wall 6c of the casing 6 may be extended to the vicinity of the lid member 30 when the panel support arm 15 is downsized and there is room in the space.
- the overhanging portion where the margin is generated in the space is eliminated, the inner overhanging space 33 is formed partway in the height direction, and the width of the main body 2 is reduced only where the inner overhanging space 33 is not provided.
- the design can also be taken.
- the side surface 2S of the main body 2 is comprised with the cover member 30 of 1 sheet over the whole height direction.
- the lid member 30 can be divided in the middle, and can be configured such that only a part of the side surface 2S can be removed.
- the lid member can be fitted only in the upper half, and the lower half can be constituted by a casing.
- the stepping motor 25 is disposed in the internal overhanging space 33 of the main body 2.
- parts are packed in the casing for the purpose of making the shape of the indoor unit as small as possible. Therefore, since a substantially rectangular parallelepiped main body has a flat side surface, other parts are provided around the stepping motor 25. It is common to be crowded.
- the periphery of the stepping motor 25 of the above-described embodiment is covered with the curved lid member 30, there is no space for placing other components, and almost the entire stepping motor 25 is exposed. Thereby, the attaching operation of the stepping motor 25 is facilitated.
- the shape of the side surface 2S of the main body 2 is a shape that protrudes into a smooth curved surface, it is possible to reduce the feeling of pressure compared to the case where the width of the main body 2 is widened.
- the stepping motor 25 is an arm drive motor for driving the panel support arm 15. Since it is important that the arm drive motor of the panel support arm 15 that must be supported so that the movable panel 3 is not displaced, it is important that the arm drive motor is arranged at a correct position. Improvement effect is expected.
- the arm drive motor is a kind of movable part.
- the movable parts of the indoor unit 1 must be suitable for a quiet space with few moving things such as a living room. Since such a movable part has a function of moving, it is generally difficult to perform an attaching operation as compared with a stationary part. Such a tendency is remarkable particularly when the movable part has to transmit or generate a large driving force.

- the curved lid member 30 surrounding the stepping motor 25 can be removed. Since the lid member 30 can be removed, when the maintenance of the stepping motor 25 is performed, there is no need to remove the casing 6 as in the conventional case, and the maintenance becomes easy. Further, even in the work of attaching a functional component such as the stepping motor 25, the work can be performed with the casing 6 covered.

Therefore, it is possible to perform an operation of attaching together with the stepping motor 25 which is a functional component disposed in the internal overhanging space 33. Thereby, the panel support arm 15 and the stepping motor 25 can be easily attached at an accurate position, the process of the attachment work is simplified, and the work efficiency is improved.

Description

本発明の一実施形態に係る空気調和装置の壁掛け型室内機は、室外に設置される室外機に冷媒配管によって接続されて、室外機とともに空気調和装置の冷媒回路を構成する。また、壁掛け型室内機は、伝送線路によって室外機と接続されており、室外機と一体になって動作を行う。そのために、壁掛け型室内機の内部には、制御回路や電気部品が実装されるプリント配線基板などが設置される。
<壁掛け型室内機の外観>
図1は、運転停止状態の壁掛け型室内機の正面図であり、図1の壁掛け型室内機の平面および側面が図2および図3に示されている。以下の説明では、壁掛け型室内機1を略して室内機1という。また、室内機1の本体2の前面2Fに向かって右側が室内機1の左であり、向かって左側が室内機1の右である。
図4は、室内機1を、室内機1の左前方斜め上から見たときの室内機1の輪郭を示す斜視図である。この図4を用いて内部張出空間について説明する。図4に示されているように、室内機1の本体2は、奥行き方向において3つの部分に分けることができる。すなわち、本体2は、取り付けられる壁面に面する背面2B近傍の背面部2cと、背面部2cの前方にある奥行き方向中央部2bと、奥行き方向中央部2bの前方にある前面部2aとからなる。前面部2aおよび背面部2cは、本体2の前面2Fや背面2Bの近傍にある極めて薄い空間である。例えば、前面部2aおよび背面部2cの奥行きは、前面2Fや背面2Bから5mm程度であり、ケーシング6の厚み程度のものである。
奥行き方向中央部2bは、前方空間SP1と、この前方空間SP1よりも左に張り出した内部張出空間SP2と、この前方空間SP1よりも右に張り出した内部張出空間SP3とからなる。内部張出空間SP2は、前方空間SP1の左の端面SF1と本体2の左の側面2Sとの間にある空間である。図4においては、この内部張出空間SP2の上面と下面に斜線が付されている。内部張出空間SP2と対称な形をした内部張出空間SP3が右の端面SF2と右の側面2Sとの間に形成されている。これら内部張出空間SP2,SP3の少なくとも一方に機能部品が配置される。なお、内部張出空間SP2,SP3に近接する近接空間については後述する。
図1から分かるように、正面から見えるのは、可動パネル3のみである。正面から眺めたときには、主に可動パネル3の平坦な前面部3aが見えて、壁が浮き出したような印象を与えるため、室内に居る居住者への圧迫感を軽減することができる。さらに、可動パネル3の側面部3bが弧を描いて滑らかに湾曲しているため、前面部3aと側面部3bの間に稜線が存在せず、稜線が鮮明に見えるものと比べて居住者から室内機1を目立たなくすることができる。
可動パネル3の側面部3bと化粧板4で構成される本体2の側面2Sは、化粧板4の部分において、徐々に本体2の横幅が小さくなる。そのため、化粧板4は、平面視において本体2の左の側面2SがS字状に緩やかな湾曲しており、右の側面2Sが逆S字状に緩やかに湾曲している。
この化粧板4は、本体2が有する蓋部材30に取り付けられている(図2参照)。そして、この蓋部材30は、本体2を覆うケーシング6に取り付けられている。ケーシング6は、図2に示すように、本体2の上面2Uにおいては格子状のグリル6bを有しており、このグリル6bの部分に第1吸込口7が形成されている。
図5は、室内機1を、室内機1の左斜め下から見た斜視図である。本体2は、下面2Dにケーシング6の底面を有している。ケーシング6の底面には、吹出口9が形成されている。この吹出口9は、本体2の底面2Dだけでなく、前面2Fにも形成されているが、この点については後述する。吹出口9から吹き出される調和空気の上下方向の風向を調節するため、吹出口9にはフラップ10が設けられている。運転停止時には、フラップ10は、図5に示すように吹出口9を塞ぐ。しかも、フラップ10が吹出口9を塞いでいる状態で、フラップ10の表面とケーシング6の底面の表面が面一になるように、互いの表面の位置が揃えられている。また、本体2の底面2Dには、左側に、側面2Sの形状に沿うように、比較的径の大きな円形の押しボタンスイッチ11が設けられる。この押しボタンスイッチ11により、電源のオンオフが行われる。電源のオンオフばかりでなく、この押しボタンスイッチ11は、赤外線を透過する材質で形成されており、押しボタンスイッチ11を透過した赤外線を本体2の内部で受光できるよう構成されている。また、押しボタンスイッチ11の周囲のリング11aは、光を透過する材質で形成されており、本体2の内部に設けられた発光ダイオードの光を外部に透過することができる。赤外線の受光部や発光ダイオードの配置については後述する。
可動パネル3は、運転時において最上点まで上昇し、運転停止時において最下点まで下降する。従って、室内機1の可動パネル3が静止するのは、最上点と最下点の2箇所である。図6乃至図10は、室内機1が運転状態になり、可動パネル3が上に持ち上げられた状態を示している。図6は室内機1の正面図であり、図7は室内機1の側面図であり、図8は室内機1の平面図であり、図9は室内機1を、室内機1の前方左斜め上方から見た斜視図であり、図10は室内機1を、室内機1の後方左斜め上方から見た斜視図である。
図6に示すように、可動パネル3が最上点に移動することにより、ケーシング6の下方に形成された第1開口部9aが正面から見える状態になる。図5を示して先にも説明した吹出口9は、この第1開口部9aと、ケーシング6の底面に形成されているがフラップ10で覆うことのできる第2開口部9bとからなる。これら第1開口部9aと第2開口部9bは、つながっており、本体2内に設けられて斜め下方に向かう吹出通路(図示省略)の出口にあたる。図6では、第2開口部9bがフラップ10で閉鎖されているが、図9では、フラップ10が回転して吹出通路内に位置するために第2開口部9bが開放されている。運転時においては、少なくとも第1開口部9aを開放するために、可動パネル3の下端部3cは、第1開口部9aの上辺の位置よりも上まで上昇する。
可動パネル3が上方に移動する際には、下端部3cの前後に移動する距離が少なく、上端部3dの前方への移動距離が長くなる。そのため、図7に示すように、側面から見ると、上端部3dが下端部3cよりも前方に移動し、可動パネル3が前方に傾斜する。それにより、可動パネル3の背面3eとケーシング6の前面6aとの間に開口部13が形成される。図6や図9では、可動パネル3の陰になって見えないが、ケーシング6の前面6aに第2吸込口が設けられている。開口部13が形成されることにより、ケーシング6の前面6aに設けられた第2吸込口から室内空気を吸込むことが可能になる。なお、第2吸込口については、後述する図16に示す。
また、同様の理由から、可動パネル3の変形によって、可動パネル3の下端部3cとケーシング6の前面6aとの間に隙間が生じることは好ましくない。可動パネル3には、プラスチックやアルミニウムとプラスチックを張り合わせたものなど比較的剛性の高くかつ軽い材料が用いられる。しかし、そのような隙間の発生を防止するには可動パネル3を構成する板状の部材の剛性だけでは不十分なため、さらに剛性を高める目的で、図8や図10に示すように、ステンレス製の中空の金属棒14などが可動パネル3の前面部3aの裏側に取り付けられる。
可動パネル3は、図8や図10に示すように、ラックギアが形成されているパネル支持アーム15によって支えられている。パネル支持アーム15は、後述するステッピングモータからラックギアに駆動力が伝達されることにより移動する。
既に説明したように室内機1に優れた外観を与えるため、本体2の前面2Fの全体ばかりでなく、本体2の側面2Sの一部をも覆うように構成される可動パネル3は、重いものとなる。それに加えて、室内空気を第2吸入口から吸込むために、許容される変形量が制限されることから、高い剛性を要求されており、可動パネル3は、さらに自重を増す傾向にある。そして、可動パネル3を単に上下にスライドさせるだけでなく、複雑な動作を要求されることから、パネル支持アーム15などの可動パネル3の支持部材に掛かる負担は大きくなる。
図12、図13および図14には、パネル支持アーム15の構造と動作を説明するために、パネル支持アーム15とその周辺の部品を含む部分を抜き出して示している。図12には、運転停止時にあって可動パネル3が最下点にある状態(閉じている状態)が示され、図14には、運転時にあって可動パネル3が最上点にある状態(開いている状態)が示されている。そして、図13には、図12の状態から図14の状態への移行途中あるいは逆に図14の状態から図12の状態への移行途中の状態が示されている。
図12乃至図14に示す可動パネル3は、アルミニウム板3mとプラスチック板3nの張り合わせ構造を有している。このプラスチック板3nの背面側には、パネル支持アーム15と連結するための第1連結部16aと第2連結部16bが設けられる。可動パネル3の上端部3d近傍に設けられる第1連結部16aは、パネル支持アーム15の上部に設けられる開口部15aと連結する。他方、第2連結部16bは、可動パネル3の下端部3cを基準として可動パネル3の高さの約4分の1の高さのところに設けられている。この第2連結部16bは、パネル支持アーム15の下部に設けられている連結部15bに連結される。可動パネル3とパネル支持アーム15は、上述の連結を行ったり解いたりすることで着脱ができるように構成されている。
このパネル支持アーム15は、2枚の板状部材を合わせて構成される薄いケース17に収納されている。この薄いケース17を構成する一方の板状部材18には、第1摺動開口15dを摺動できるように第1摺動開口15d内に嵌っている円柱状の第1支持部材20aと、第2摺動開口15eを摺動できるように第2摺動開口15e内に嵌っている円柱状の第2支持部材20bとがビス止めされている。そして、板状部材18の周囲に、ローラー15fが当たりながら動くガイド部18aが形成されている。
ガイド部18aが凹部18a2を持ち、第2摺動開口15eが下部開口15e2を持っているため、可動パネル3は複雑な動きをする。第2摺動開口15eの上部開口15e1を上から下に向けて第2支持部材20bが摺動しているときには、可動パネル3が上方に移動しつつ可動パネル3の上端部3dがケーシング6の前面6aから大きく離れる一方、下端部3cが前面6aから少し離れる。そして、第2支持部材20bが下部開口15e2に入ると、ローラー15fが凹部18a2に入り込む。そのとき、パネル支持アーム15は、第1支持部材20aを中心に回動しつつ移動し、可動パネル3の上端部3dはケーシング6の前面6aからさらに大きく離れるような動きをする一方、下端部3cは逆に前面6aに近づくような動きをする。この可動パネル3の動きの軌跡を図15に示す。
上述のような重い可動パネル3と、複雑な動きをするパネル支持アーム15とが適切に動作するように取り付ける作業は、周囲に他の部材が密集していると難しくなる。そのため、室内機1においては、パネル支持アーム15などの部材が、本体2の奥行き方向中央部2bの内部張出空間に設けられる。
<パネル支持アーム15の設置場所>
次に、図12乃至図14を用いて説明したパネル支持アーム15とその周囲の部材の設置場所について説明する。図16および図17には、室内機1の可動パネル3を取り外した状態が示されている。図16は室内機1の正面図であり、図17は室内機1の平面図である。
パネル支持アーム15は、図16に示されている張出領域2d,2eに対応する位置に配置されている。正面視において、この張出領域2d,2eの位置は、可動パネル3の側面部3bの位置に重なる。張出領域2d,2eには蓋部材30が取り付けられ、本体2は、蓋部材30の分だけケーシング6よりも横方向に張り出した形状を呈している。この蓋部材30は、ビス31によって、ケーシング6に固定される。また、図12乃至図14において説明したパネル支持アーム15とその周囲の部材は、ビス32によってケーシング6に固定される。
図18に示すように、蓋部材30とケーシング6との間において、奥行き方向中央部2bに対応する部分に大きな内部張出空間33が形成される。この内部張出空間33があるためにステッピングモータ25を薄いケース17の側方外側に配置することができる。このケース17は、板状部材18と透明の板状部材19を合わせて構成される。この透明の板状部材19にステッピングモータ25が嵌め込まれている。図18から分かるように、断面が洋梨のように扁平な下膨れの円形をした円筒を縦に2分割した形状を蓋部材30が有していて、比較的余分な空間が本体2の内部に形成されていない。例えば、二点鎖線で示したような形状であると、本体2の背面2Bに近いところに余分な大きな空間34が形成される。このような余分な空間を削り落として、膨出した蓋部材30の形状を滑らかに湾曲させることで、本体2の側面2Sの形状を、居住者に対して圧迫感の少ない外観に仕上げることができている。
このように、組立が完了した後においても、蓋部材30を取り外すと、ステッピングモータ25とパネル支持アーム15周りの全体を立体的に露出させることができる。そのため、工具を差し込む方向の制限が少なくなり、メンテナンス作業も容易になる。
また、透明な板状部材19がパネル支持アーム15の外側側面を覆っているため、パネル支持アーム15、被駆動ギア21、駆動ギア22、およびステッピングモータ25などの駆動部品の動きを透明な板状部材19を透して見て確認することができる。
上述のように、可動パネル3の支持構造においては、ローラー15fが凹部18a2に入ることで、可動パネル3の支持が補助されている。一旦、ローラー15fが凹部18a2に入ると、ローラー15fが凹部18a2から出るためには、凹部18a2とガイド壁18a1との高低差を越えなければならなくなるため、支持を補助できるのである。従って、リミットスイッチ26では、ローラー15fが凹部18a2に入る位置までパネル支持アーム15が確実に移動したこと(最上点に達していること)を検知する必要がある。このようなことから、リミットスイッチ26や板状片28を正しい配置位置に正確に設定することが必要になる。内部張出空間33を使うことで、パネル支持アーム15を収納したケース17ごとリミットスイッチ26や板状片28を設置できるので、取り付けが簡単で正確に行える。また、メンテナンス時には、ケース17の周辺の部材が立体的に露出するため、工具や人の手による調整や部品の取替えが簡単に行える。
また、押しボタンスイッチ11の周囲にあるリング11aの上方には、異なる発光色の発光ダイオード42が配置されている。この発光ダイオード42もプリント配線基板40に搭載されている。そして、暖房や冷房などの運転の違いを発光色で伝達するため、種々の色に押しボタンスイッチ11の周囲のリング11aを光らせることができるよう構成されている。このような発光ダイオード42や受光素子41のメンテンナンスも機能部品のメンテナンスである。
室内機1の左側面を構成する左側の蓋部材30の六面図および段面図を図20および図23に示す。すなわち、図20(a)は蓋部材30の正面図、図20(b)は右側面図、図20(c)は背面図、そして図20(d)が左側面図である。また、図23(a)は平面図、図23(b)は底面図、そして図23(c)はB-B線断面図である。
既に説明したように、蓋部材30が立体的形状を有することおよび、その蓋部材30が本体2の側面2Sに配置されることによって、内部張出空間33が形成される。できるだけ、室内機1の本体2の外形を小さくするため、余分な空間を本体2の内部に設けないことが好ましいことから、蓋部材30の形状は、ステッピングモータ25がちょうど納まるようにステッピングモータ25の近傍では外に向かって凸の滑らかな曲線を描く。図23(a)を用いて平面視した場合の蓋部材30の形状を説明すると、まず、背面2B側の始端から前面2F側の終端に向かうに従って徐々に側面が本体2の幅方向に膨らむ。次に、約3分の1のこと頃すぎたところから前面2Fに至る部分は略半円形の弧を描く。そして、背面2Bの始端と前面2Fの終端は、本体2の幅方向(横方向)においてほぼ同じ位置にある。そのため、機能部品を収納するのに十分な内部張出空間33が略半円形の弧の内側に形成される。さらに詳細に見ると、蓋部材30が最も張り出すところに段差が形成されている。この段差は、可動パネル3と化粧板4との外面を面一にするために形成されているものである。
この蓋部材30には、背面側に掛止爪35が設けられている。この掛止爪35をケーシング6の所定の穴に差し込み、ビス31を穴36に差し込んでケーシング6のネジ穴にねじ込むことで、簡単に蓋部材30をケーシング6に装着することができる。そして、蓋部材30の裏面側には、蓋部材30の補強のためにリブ37が形成されている。
(1)上記実施形態では、本体2の側面2Sを取り外すことができる蓋部材30で構成している。しかし、本体2の側面2Sは、取り外すことができないものであってもよく、例えばケーシング6で本体2の側面2Sを構成してもよい。この場合、メンテナンスの利便性は低下するが、従来に比べればメンテナンスは容易であり、また、取り付け作業も従来より容易になる。従来、ケーシングを外すと、側面に密集した部品が平面状に広がることになるのに対し、上記実施形態のように張り出した側面形状を持たせれば、張り出した側面形状に合わせて密集した部品が広がる。従って、上記実施形態のように側面を凸状に湾曲させることにより、密集した部品の形状が側面形状に沿って立体的になるため、工具や人の手が入り易くなる部分ができる。それにより、取り付け作業、引いてはメンテナンス作業の効率が改善されることになる。
(3)上記実施形態では、本体2の側面2Sを高さ方向の全体にわたって、一枚の蓋部材30で構成している。しかし、この蓋部材30は、途中で分割することもでき、側面2Sの一部分だけを取り外せるように構成することもできる。例えば、上半分だけに蓋部材を嵌め込み、下半分はケーシングで構成することもできる。
(a)
壁掛け型室内機1は、本体2の内部張出空間33に、ステッピングモータ25が配置される。従来であれば、室内機の形状をできる限り小さくする目的で部品をケーシング内に詰め込むことから、従来のような略直方体状の本体は側面が平坦なため、ステッピングモータ25の周囲に他の部品が密集するのが一般的である。それに対して、内部張出空間上記実施形態のステッピングモータ25の周囲が湾曲した蓋部材30で覆われるため、他の部品の配置されるスペースがなく、ステッピングモータ25のほぼ全体が露出する。それにより、ステッピングモータ25の取り付け作業が容易になる。一方、本体2の側面2Sの形状が滑らかな曲面状に張り出した形状であるため、本体2の横幅が広がる場合に比べて圧迫感を軽減することができる。
(b)
パネル支持アーム15は、本体2の前面2Fの全体を覆うとともに本体2の側面2Sの一部をも覆う可動パネル3を支持するものである。上記実施形態においては、パネル支持アーム15が近接空間33aに配置される。そのため、内部張出空間33に配置される機能部品であるステッピングモータ25と一緒に取り付ける作業を行うことができる。それにより、簡単に正確な位置にパネル支持アーム15とステッピングモータ25を取り付けることができ、取り付け作業の工程が簡素化されて、作業効率が向上する。上記実施の形態では、パネル支持アーム15は、近接空間33aに配置されるが、内部張出空間33に配置される場合あるいは内部張出空間33と近接空間33aに配置される場合であっても作業効率が向上するのは同様である。
(c)
受光素子41(受光部)は、内部張出空間33に配置される。そして、押しボタンスイッチ11を透過してきた赤外線を受光する。受光素子41が本体2の外部から離れているため室内の環境変化などの影響を受け難くなる。内部張出空間に受光素子41と制御部があるプリント配線基板40が配置されるので、受光素子41とその制御部のあるプリント配線基板40の取り付け作業や取り外し作業などが行い易くなる。
