Description

本発明は、建物の天井内に設置される空気調和装置であって、空調対象室内の空気および空調対象室内以外の空気を取り込んで空調処理する天井埋込型空気調和装置に関する。   The present invention relates to an air conditioner installed in a ceiling of a building, and relates to a ceiling-embedded air conditioner that takes in air in an air-conditioning target room and air outside the air-conditioning target room and performs air-conditioning processing.

従来、この種の天井埋込型空気調和装置は例えば下記の特許文献１に開示されている。下記文献開示の天井埋込型空気調和装置では、建物の天井内に設置される箱状の本体ケースの内部に熱交換器および送風機が収容されており、本体ケースの内部が送風機を境に空気吸込側空間と空気吹出側空間とに区画されている。また、空調対象室内空気を本体ケース内に取り入れる主取入口が空気吸込側空間の本体ケースの底面または背面に開口して形成されている。   Conventionally, this type of ceiling-embedded air conditioner is disclosed in, for example, Patent Document 1 below.

特開平８−２７０９７８号公報JP-A-8-270978

ところで、空気吸込側空間における本体ケースの一側板に、空調対象室内空気以外の空気を空気吸込側空間に取り入れる空気取入ダクトが接続される場合が増えている。このとき、取付スペースによる規制から空気取入ダクトが接続されない他方の側板に、制御基盤、端子、スイッチなどの電気部品を収容した電気品ボックスが取り付けられる。その場合、天井内の構造物、スペース、室内側の間仕切りや壁の配置などにより、電気品ボックスと空気取入ダクトを互いに付け換えたいことがある。しかしながら、従来の空気調和装置は電気品ボックスと空気取入ダクトを付け換え可能な仕様にされていなかったのである。   By the way, the case where the air intake duct which takes in air other than air for air-conditioning into the air suction side space is connected to the one side plate of the main body case in the air suction side space is increasing. At this time, an electrical component box containing electrical components such as a control board, terminals, and switches is attached to the other side plate to which the air intake duct is not connected due to restrictions by the installation space. In that case, there is a case where it is desired to replace the electrical box and the air intake duct with each other due to the structure in the ceiling, the space, the partition on the indoor side, the arrangement of the walls, and the like. However, the conventional air conditioner has not been designed to replace the electrical box and the air intake duct.

本発明は、上記した従来の問題点に鑑みてなされたものであって、電気品ボックスと空気取入ダクトを本体ケースの両側の側板間で付け換えることのできる天井埋込型空気調和装置の提供を目的とする。   The present invention has been made in view of the above-described conventional problems, and is a ceiling-embedded air conditioner that can replace an electrical component box and an air intake duct between side plates on both sides of a main body case. For the purpose of provision.

上記目的を達成するために、本発明に係る天井埋込型空気調和装置は、天井内に設置される箱状の本体ケースの内部に熱交換器および送風機が収容されるとともに、本体ケースの内部が送風機を境に空気吸込側空間と空気吹出側空間とに区画され、空調対象室内空気をケース内に取り入れる主取入口が本体ケースの空気吸込側空間に開口して形成されている天井埋込型空気調和装置において、本体ケースが、少なくとも、一側板と、一側板に対し送風路をはさんで対面配置された他側板と、一側板の上部と他側板の上部をつなぐ天板と、一側板の下部と他側板の下部をつなぐ底板とを備えて構成され、一側板または他側板のいずれか一方に、空調対象室内空気以外の空気を空気吸込側空間に取り入れる空気取入ダクトが接続される一の副取入口と、空気取入ダクトを着脱可能に接続するための一の接続手段とが設けられ、一の副取入口が設けられていない他方の側板に、打ち抜きにより別の副取入口が形成されるノックアウト部と、空気取入ダクトを別の副取入口に接続するための別の接続手段とが設けられ、一の副取入口が設けられていない他方の側板に、電気部品を収容した電気品ボックスが一の取付手段を介して着脱可能に取り付けられ、一の副取入口が設けられている一方の側板に、電気品ボックスを取り付けるための別の取付手段が設けられているものである。 In order to achieve the above object, a ceiling-embedded air conditioner according to the present invention includes a heat exchanger and a blower housed inside a box-shaped body case installed in the ceiling, and an interior of the body case. Is divided into an air suction side space and an air blowout side space with the blower as a boundary, and a ceiling embedding in which a main intake port for taking indoor air to be conditioned into the case opens into the air suction side space of the main body case In the type air conditioner, the main body case includes at least one side plate, another side plate facing the one side plate across the air passage, a top plate connecting the upper portion of the one side plate and the upper portion of the other side plate, An air intake duct that takes in air other than the air to be air-conditioned into the air suction side space is connected to either the one side plate or the other side plate, and includes a bottom plate that connects the lower portion of the side plate and the lower portion of the other side plate. Ruichi no Sub-intake And a connecting means for detachably connecting the air intake duct, and a knockout in which another sub-intake is formed by punching on the other side plate not provided with one sub-intake Part and another connection means for connecting the air intake duct to another sub-intake, and an electrical component box containing an electrical component on the other side plate not provided with one sub-intake Is attached detachably through one attachment means, and another attachment means for attaching the electrical component box is provided on one side plate provided with one auxiliary intake.

また、前記構成において、電気品ボックスが取り付けられた他方の側板において空気が流通する空気吸込側空間内の所定部位と対面する位置に、一の温度センサ挿入用穴が設けられるとともに、電気品ボックスが取り付けられていない一方の側板において一の温度センサ挿入用穴に対し送風方向と直交する対面位置に、他の温度センサ挿入用穴が設けられているものである。   In the above configuration, the temperature sensor insertion hole is provided at a position facing a predetermined portion in the air suction side space through which air flows on the other side plate to which the electrical box is attached. The other temperature sensor insertion hole is provided at the facing position perpendicular to the air blowing direction with respect to the one temperature sensor insertion hole in the one side plate to which is not attached.

そして、前記した各構成において、本体ケース内部の熱交換器を送風方向に傾斜配置し、熱交換器の上方位置の天板に、下向きに陥入した溝条を一側板と他側板を結ぶ方向に沿って形成し、溝条内に、一側板から他側板へまたは他側板から一側板へ向かう配線を収容したものである。
尚、本発明において「一の」というときは、数的に「ひとつの」という意味でなく、「或る」の意味に近い概念であり、複数のものも含む。 In each of the above-described configurations, the heat exchanger inside the main body case is disposed in a slanting direction in the air blowing direction, and a groove that is indented downward is formed on the top plate at the upper position of the heat exchanger and the direction in which the one side plate and the other side plate are connected. , And the wiring from the one side plate to the other side plate or from the other side plate to the one side plate is accommodated in the groove.
In the present invention, “one” does not mean “one” numerically but is a concept close to the meaning of “a certain”, and includes a plurality of things.

本発明によれば、一方の側板の一の副取入口に一の接続手段によって空気取入ダクトが接続され、他方の側板に一の取付手段を介して電気品ボックスが着脱可能に取り付けられる。そして、空気取入ダクトと電気品ボックスを互いに反対側の側板に付け換えるときは、ノックアウト部が打ち抜かれて別の副取入口が他方の側板に形成される。この別の副取入口に空気取入ダクトが別の接続手段によって接続される。また、他方の側板から取り外された電気品ボックスが一方の側板に別の取付手段を介して取り付けられる。従って、室内の間仕切り、天井内における鉄筋や天井スラブなどの配置状況による規制から、空気取入ダクトと電気品ボックスをそれぞれの当初位置に取り付けることが不適切な場合でも、空気取入ダクトと電気品ボックスを互いに反対側の側板に付け換えることができる。これにより、装置の天井内設置作業に融通性がもたらされ、設置作業効率が格段に向上する。   According to the present invention, the air intake duct is connected to one sub-inlet of one side plate by one connection means, and the electrical box is detachably attached to the other side plate via one attachment means. When the air intake duct and the electrical component box are replaced with the side plates opposite to each other, the knockout portion is punched and another sub intake port is formed on the other side plate. An air intake duct is connected to this other sub-intake by another connecting means. Moreover, the electrical component box removed from the other side plate is attached to the one side plate via another attachment means. Therefore, even if it is inappropriate to install the air intake duct and the electrical box in their original positions due to restrictions due to the layout of indoor partitions, reinforcing bars and ceiling slabs in the ceiling, etc., the air intake duct and electrical The product box can be replaced with opposite side plates. Thereby, flexibility is provided in the installation work in the ceiling of the apparatus, and the installation work efficiency is remarkably improved.

また、電気品ボックスが取り付けられている他方の側板に設けられた一の温度センサ挿入用穴から、温度センサが空気吸込側空間内で空気の流通する所定部位に挿入されて適切な吸込み空気の温度が検知される。そこで、電気品ボックスを他方の側板から一方の側板に付け換えるときは、一の温度センサ挿入用穴から取り外された温度センサが、他の温度センサ挿入用穴から空気吸込側空間内の所定部位に挿入されるから、適切な吸込み空気の温度を同様に検知することができる。従って、電気品ボックスの付け換えに付随する温度検知の支障を生じない。   In addition, from one temperature sensor insertion hole provided on the other side plate to which the electrical box is attached, the temperature sensor is inserted into a predetermined portion where air flows in the air suction side space, and the appropriate suction air is supplied. Temperature is detected. Therefore, when changing the electrical component box from the other side plate to the one side plate, the temperature sensor removed from one temperature sensor insertion hole is moved from the other temperature sensor insertion hole to a predetermined part in the air suction side space. Therefore, the appropriate intake air temperature can be detected in the same manner. Therefore, there is no problem of temperature detection accompanying the replacement of the electrical box.

そして、電気品ボックスを他方の側板から一方の側板に付け換える場合において、他方の側板から引き出された例えば冷媒流量制御装置からの配線を一方の側板側に渡す必要があるが、本発明では天板上に形成した溝条内に配線を収容するようになっているから、本体ケースの内部で配線を渡さずに済み、風の抵抗を受けることなく、かつ、ヒータを装着した機種においてはヒータの熱の影響を受けることがない。そして、本体ケースの上面で配線を渡すにも拘わらず、熱交換器の傾斜配置により必然的に生じる空間を利用した溝条内に配線が収容されるので、本体ケースの高さ方向の薄型化を阻害することがない。これらの効果は例えば外部からの接続配線を一方の側板から他方の側板側へ渡して接続する工事においても有効である。   When replacing the electrical box from the other side plate to the one side plate, for example, the wiring from the refrigerant flow control device drawn out from the other side plate needs to be passed to the one side plate. Since the wiring is accommodated in the groove formed on the plate, it is not necessary to pass the wiring inside the main body case, and it is not subject to wind resistance. It is not affected by the heat. Even though the wiring is passed on the upper surface of the main body case, the wiring is accommodated in the groove using the space inevitably generated by the inclined arrangement of the heat exchanger, so the main body case is thinned in the height direction. Will not be disturbed. These effects are also effective in, for example, construction in which connection wiring from the outside is connected from one side plate to the other side plate.

A drain pump 60 is attached to the front portion of the side plate 12. The drain pump 60 communicates with the drain pan 16 via a hose 59, and drains water dripped on the drain pan 16 from the heat exchanger 3 during cooling operation.

電気品ボックス２２は、図４および図６（ｃ）に示すように、取り付け面が開口した矩形箱状に形成されている。側方に張り出した両側の辺部には、ビス３６（図２参照）が挿通されるビス挿通穴３９，４０がそれぞれ形成されている。電気品ボックス２２が取り付けられる位置の側板１２には、それぞれ雌ネジ部を有するネジ穴６２，６４が形成されている。電気品ボックス２２が取り付けられる位置の側板１３には、それぞれ雌ネジ部を有するネジ穴６６，６８が形成されている。 As shown in FIG. 4 and FIG. 6C, the electrical component box 22 is formed in a rectangular box shape with an open attachment surface. Screw insertion holes 39 and 40 through which screws 36 (see FIG. 2) are inserted are respectively formed on the sides on both sides protruding sideways. Screw holes 62 and 64 having female screw portions are formed in the side plate 12 at the position where the electrical component box 22 is attached. Screw holes 66 and 68 each having a female screw portion are formed in the side plate 13 where the electrical box 22 is attached.

すなわち、上記の取付手段（一の取付手段）６３は、側板１２のビス穴６２と、ビス穴６２に螺止されるビス３６とから構成される。取付手段（一の取付手段）６５は、側板１２のビス穴６４と、ビス穴６２に螺止されるビス３６とから構成される。一方、取付手段（別の取付手段）６７は、側板１３のビス穴６６と、ビス穴６６に螺止されるビス３６とから構成される。取付手段（別の取付手段）６９は、側板１３のビス穴６８と、ビス穴６８に螺止されるビス３６とから構成される。但し、本発明に係る一のまたは別の取付手段としては、前記したビス穴とビスの組み合わせに限るものでなく、例えば係合穴とこれに係合する係合突起（いずれも図示省略）との組み合わせなどが挙げられる。 That is, the mounting means (one mounting means) 63 includes a screw hole 62 of the side plate 12 and a screw 36 screwed into the screw hole 62. The attachment means (one attachment means) 65 includes a screw hole 64 of the side plate 12 and a screw 36 screwed into the screw hole 62. On the other hand, the attaching means (another attaching means) 67 includes a screw hole 66 of the side plate 13 and a screw 36 screwed into the screw hole 66. The attachment means (another attachment means) 69 includes a screw hole 68 of the side plate 13 and a screw 36 screwed into the screw hole 68. However, one or another mounting means according to the present invention is not limited to the combination of the screw hole and the screw described above, and for example, an engagement hole and an engagement protrusion (both not shown) that engage with the engagement hole. The combination etc. are mentioned.

送風機４は、図５に示すように、側面に空気の吸込口４３が形成され前面に空気の吹出口４２が形成されたファンケーシング７１を備えている。ファンケーシング７１にはファン４７が内装されている。ファン４７はモータ１８と駆動連結されている。主取入口７からの空気は矢印４４のように流れて、吸込口４３からファンケーシング７１内に流入する。その際、主取入口７からの空気は部位４５の近傍において送風機４への流れ込みが速く、部位４６において送風機４への流れ込みが遅くなっている。吸込口４３からファンケーシング７１内に流入した空気は、ファン４７の回転作用により吹出口４２から矢印４８のように送り出され、区画板９の送風口３８を経て空気吹出側空間６内の熱交換器３を通過し吹出口８から吹き出される。 As shown in FIG. 5, the blower 4 includes a fan casing 71 in which an air inlet 43 is formed on a side surface and an air outlet 42 is formed on a front surface. A fan 47 is internally provided in the fan casing 71. The fan 47 is drivingly connected to the motor 18. Air from the main intake 7 flows as indicated by an arrow 44 and flows into the fan casing 71 from the suction port 43. At that time, the air from the main intake port 7 flows into the blower 4 quickly in the vicinity of the portion 45, and the flow into the blower 4 becomes slow at the portion 46. The air that has flowed into the fan casing 71 from the suction port 43 is sent out from the outlet 42 as indicated by the arrow 48 by the rotational action of the fan 47, and exchanges heat in the air outlet side space 6 through the air outlet 38 of the partition plate 9. It passes through the vessel 3 and is blown out from the outlet 8.

熱交換器３は本体ケース２の空気吹出側空間６内で送風方向（図２中の矢印Ｆ方向）に向かって下向きに傾斜して配置されている。この場合、熱交換器３上方位置の天板１４が平たんであると、熱交換器３の上端と天板１４下面との間に側面視で三角形のスペースが生じる。そこで、かかるスペースを埋めるように、熱交換器２の上方位置の天板１４に、下向きに陥入した溝条２７が側板１２と側板１３を結ぶ方向に沿って形成されている。また、区画板９の空気吹出側空間６側にはヒータ１０が取り付けられている。   The heat exchanger 3 is disposed so as to be inclined downward in the air blowing side space 6 of the main body case 2 toward the blowing direction (the direction of arrow F in FIG. 2). In this case, if the top plate 14 above the heat exchanger 3 is flat, a triangular space is generated between the upper end of the heat exchanger 3 and the lower surface of the top plate 14 in a side view. Therefore, a groove 27 that is depressed downward is formed along the direction connecting the side plate 12 and the side plate 13 in the top plate 14 located above the heat exchanger 2 so as to fill the space. A heater 10 is attached to the air blowing side space 6 side of the partition plate 9.

ここで、図６に示すように、空気吸込側空間５内のイからホの箇所にそれぞれ温度センサ４１を設置して各箇所の空気温度を実測し、空調対象室内で実測した空気温度と比較した。その結果を図６（ｂ）のグラフに示す。送風機４近傍の空気の流れには偏りがありモータ１８からの熱の影響も受けるため、空気が滞留しやすい。グラフから明らかなように、ロからホの箇所では正確な空調対象室内の空気温度を検知できなかったが、箇所イ（所定部位）では最も空調対象室内の空気温度に近い温度を検知できることが判った。そこで、電気品ボックス２２が取り付けられた側板１２において空気吸込側空間５内の箇所イ（所定部位）と対面する位置に、温度センサ挿入用穴２３が設けられている。電気品ボックス２２が取り付けられていない側板１３においては側板１２の温度センサ挿入用穴２３に対し送風方向（図２中の矢印Ｆ方向）と直交する対面位置に、温度センサ挿入用穴２４が設けられている。   Here, as shown in FIG. 6, temperature sensors 41 are respectively installed at locations i to e in the air suction side space 5 to measure the air temperature at each location, and compared with the air temperature measured in the air conditioning target room. did. The result is shown in the graph of FIG. Since the air flow in the vicinity of the blower 4 is uneven and is also affected by the heat from the motor 18, the air tends to stay. As is clear from the graph, the air temperature in the air-conditioning target room could not be detected accurately at the location from b to ho, but it was found that the temperature closest to the air temperature in the air-conditioning target room could be detected at location a (predetermined location). It was. In view of this, a temperature sensor insertion hole 23 is provided at a position facing the location a (predetermined location) in the air suction side space 5 on the side plate 12 to which the electrical component box 22 is attached. In the side plate 13 to which the electrical box 22 is not attached, a temperature sensor insertion hole 24 is provided at a facing position perpendicular to the air blowing direction (arrow F direction in FIG. 2) with respect to the temperature sensor insertion hole 23 of the side plate 12. It has been.

そして、電気品ボックス２２の下部には、図６（ｃ）に示すように、温度センサ挿入用穴２５、温度センサ挿入用穴２６が形成されている。温度センサ挿入用穴２５は、電気品ボックス２２を側板１２に取り付けたときに側板１２の温度センサ挿入用穴２３と連通する位置に形成されている。温度センサ挿入用穴２６は、電気品ボックス２２を側板１２から側板１３に付け換えたときに側板１３の温度センサ挿入用穴２４と連通する位置に形成されている。これにより、電気品ボックス２２を側板１２または側板１３のいずれに取り付けた場合でも温度センサ４１を箇所イの位置に挿入・配置することができる。温度センサ４１は、図６（ｄ）に示すように、電気品ボックス２２の温度センサ挿入用穴２５または温度センサ挿入用穴２６に嵌着されたブッシュ４９により保持固定される。 And as shown in FIG.6 (c), the temperature sensor insertion hole 25 and the temperature sensor insertion hole 26 are formed in the lower part of the electrical component box 22. FIG. The temperature sensor insertion hole 25 is formed at a position communicating with the temperature sensor insertion hole 23 of the side plate 12 when the electrical component box 22 is attached to the side plate 12. The temperature sensor insertion hole 26 is formed at a position communicating with the temperature sensor insertion hole 24 of the side plate 13 when the electrical box 22 is replaced from the side plate 12 to the side plate 13. As a result, the temperature sensor 41 can be inserted / placed at the position a regardless of whether the electrical box 22 is attached to either the side plate 12 or the side plate 13. As shown in FIG. 6D, the temperature sensor 41 is held and fixed by a bush 49 fitted in the temperature sensor insertion hole 25 or the temperature sensor insertion hole 26 of the electrical component box 22.

この空気調和装置１は、図７に示すように、空調対象室内Ｔの天井内Ｓに設置される。空気調和装置１の主取入口７は天井Ｒに形成された空気取入口５１と導風路５２を介して連結され、空気調和装置１の吹出口８は天井Ｒに形成された空気送出口５４と導風路５３を介して連結される。この空気調和装置１は空調対象室内Ｔに設置されたリモコン５０により制御目標が設定される。 As shown in FIG. 7, the air conditioner 1 is installed in the ceiling S of the air-conditioning target room T. The main intake 7 of the air conditioner 1 is connected to an air intake 51 formed in the ceiling R via an air guide path 52, and the air outlet 8 of the air conditioner 1 is connected to an air outlet 54 formed in the ceiling R. And are connected via a wind guide path 53. The air conditioning apparatus 1 has a control target set by a remote controller 50 installed in the air-conditioned room T.

上記した構成の天井埋込型空気調和装置１によれば、側板１３の副取入口１９に接続手段６１によって空気取入ダクト５５が接続され、側板１２に取付手段６３，６５を介して電気品ボックス５５が着脱可能に取り付けられる。そして、空気取入ダクト５５と電気品ボックス２２を互いに反対側の側板１２，１３に付け換えるときは、ノックアウト部２０が打ち抜かれて副取入口２１が側板１２に形成される。この副取入口２１に空気取入ダクト５５が接続手段７０によって接続される。また、側板１２から取り外された電気品ボックス２２が側板１３に取付手段６７，６９を介して取り付けられる。従って、室内の間仕切り５７、天井内Ｓにおける鉄筋５８や天井スラブなどの配置状況による規制から、空気取入ダクト５５と電気品ボックス２２をそれぞれの標準位置に取り付けることが不適切な場合でも、空気取入ダクト５５と電気品ボックス２２を互いに反対側の側板に付け換えることができる。これにより、この空気調和装置１の天井内設置作業に融通性がもたらされ、設置作業効率が格段に向上するのである。   According to the ceiling-embedded air conditioner 1 having the above-described configuration, the air intake duct 55 is connected to the sub intake port 19 of the side plate 13 by the connecting means 61, and the electrical product is attached to the side plate 12 via the attaching means 63 and 65. The box 55 is detachably attached. Then, when the air intake duct 55 and the electrical component box 22 are replaced with the side plates 12 and 13 on the opposite sides, the knockout portion 20 is punched and the sub-inlet 21 is formed in the side plate 12. An air intake duct 55 is connected to the sub-intake 21 by connection means 70. Further, the electrical component box 22 removed from the side plate 12 is attached to the side plate 13 via attachment means 67 and 69. Therefore, even if it is inappropriate to attach the air intake duct 55 and the electrical component box 22 to the respective standard positions due to restrictions due to the arrangement of the indoor partition 57, the reinforcing bars 58 and the ceiling slabs in the ceiling S, etc. The intake duct 55 and the electrical box 22 can be replaced with side plates opposite to each other. Thereby, flexibility is provided for the installation work in the ceiling of the air conditioner 1, and the installation work efficiency is remarkably improved.

ここで、図８に示すように、間仕切り５７，５７で囲まれた空調対象室内Ｔの天井内Ｓの鉄筋５８，５８間に空気調和装置１が設置されている例を挙げる。図８（ａ）に示す空気調和装置１は、側板１２に電気品ボックス２２が取り付けられ側板１３に空気取入ダクト５５が取り付けられた標準仕様であり、汎用構造の天井内Ｓに設置されている。この場合、電気品ボックス２２側の天井に点検口５６が設けられており点検その他に支障を生じない。それに対し、同図（ｂ）に示した建物構造では、標準仕様における電気品ボックス２２の真下に間仕切り５７が存在するため、点検口５６を設けることができない。このような場合、電気品ボックス２２を側板１２から側板１３へ付け換え、空気取入ダクト５５を側板１３から側板１２へ付け換える。これにより、同図（ｃ）に示すように、付け換え後の電気品ボックス２２下方の天井に点検口５６を設けることができる。   Here, as shown in FIG. 8, an example in which the air conditioner 1 is installed between the reinforcing bars 58 and 58 in the ceiling S of the air-conditioning target room T surrounded by the partitions 57 and 57 will be given. The air conditioner 1 shown in FIG. 8A is a standard specification in which the electrical box 22 is attached to the side plate 12 and the air intake duct 55 is attached to the side plate 13, and is installed in the ceiling S of the general-purpose structure. Yes. In this case, an inspection port 56 is provided in the ceiling on the electric component box 22 side, so that no trouble is caused in inspection or the like. On the other hand, in the building structure shown in FIG. 5B, the partition 57 is present directly below the electrical box 22 in the standard specification, and therefore the inspection port 56 cannot be provided. In such a case, the electrical box 22 is changed from the side plate 12 to the side plate 13, and the air intake duct 55 is changed from the side plate 13 to the side plate 12. Thereby, as shown to the figure (c), the inspection port 56 can be provided in the ceiling below the electrical equipment box 22 after replacement | exchange.

また、図９（ａ）に示すように、側板１２に取り付けられていたドレンポンプ６０も図８（ｃ）の点検口５６から点検する必要がある場合や、側板１３側から排水せざるを得ない場合があるため、図９（ｂ）に示すように、電気品ボックス２２とともに側板１２から側板１３へ付け換えられる。これにより、電気品ボックス２２側の点検口５６からドレンポンプ６０の点検も行なうことができ、側板１３側から排水させることができる。   Further, as shown in FIG. 9 (a), the drain pump 60 attached to the side plate 12 also needs to be inspected from the inspection port 56 in FIG. 8 (c), or must be drained from the side plate 13 side. Since there is no case, as shown in FIG. 9B, the side plate 12 is replaced with the side plate 13 together with the electrical box 22. Thereby, the drain pump 60 can also be inspected from the inspection port 56 on the electrical component box 22 side, and can be drained from the side plate 13 side.

また、電気品ボックス２２が取り付けられている側板１２に設けられた温度センサ挿入用穴２３から、温度センサ４１が空気吸込側空間５内で空気が最もよく流通する箇所イ（所定部位）に挿入されて空調対象室内の空気温度にほぼ等しい吸込み空気温度が検知される。そこで、電気品ボックス２２を側板１２から側板１３に付け換えたときは、温度センサ挿入用穴２３から取り外された温度センサ４１が、電気品ボックス２２の温度センサ挿入用穴２５および側板１３の温度センサ挿入用穴２４から空気吸込側空間５内の箇所イに挿入されるので、適切な吸込み空気の温度を、側板１２側に取り付けていたときと同様に正しく検知することができる。従って、電気品ボックス２２の付け換えに付随する温度検知の支障を回避することができる。   In addition, the temperature sensor 41 is inserted into a place (predetermined part) where the air flows best in the air suction side space 5 from the temperature sensor insertion hole 23 provided in the side plate 12 to which the electrical component box 22 is attached. Then, the intake air temperature substantially equal to the air temperature in the air-conditioning target room is detected. Therefore, when the electrical box 22 is replaced from the side plate 12 to the side plate 13, the temperature sensor 41 removed from the temperature sensor insertion hole 23 causes the temperature sensor insertion hole 25 of the electrical box 22 and the temperature of the side plate 13 to change. Since it is inserted from the sensor insertion hole 24 into the location a in the air suction side space 5, the appropriate temperature of the suction air can be correctly detected in the same manner as when it is attached to the side plate 12 side. Therefore, the trouble of the temperature detection accompanying the replacement of the electrical component box 22 can be avoided.

他方、温度センサ４１を側板１２に取り付けたままで、電気品ボックス２２を側板１２から側板１３へ付け換える場合は、温度センサ４１からの配線を側板１２から側板１３へ渡して電気品ボックス２２へ接続する必要が生じる。その場合、配線を渡す経路として、図６（ａ）中の箇所ヘ〜チが考えられる。箇所トは風量の影響が少ないが、ヒータ１０からの熱の影響が大きく配線が破損するおそれがある。箇所チは送風の抵抗となるために風量を低下させたりあるいは消費電力量が増大したりする。また、箇所トほどでないがヒータ１０からの熱の影響も受ける。それに対し、溝条２７内である箇所ヘは、本体ケース２の外部であるから、ヒータ１０からの熱の影響を受けることがなく、送風を妨げたりしない。   On the other hand, when the electrical product box 22 is changed from the side plate 12 to the side plate 13 while the temperature sensor 41 is attached to the side plate 12, the wiring from the temperature sensor 41 is passed from the side plate 12 to the side plate 13 and connected to the electrical product box 22. Need to do. In that case, the position H in FIG. 6A can be considered as a route for passing the wiring. The location G is less affected by the air volume, but the effect of heat from the heater 10 is great and the wiring may be damaged. The location h becomes a resistance to blowing air, so that the air volume is reduced or the power consumption is increased. In addition, although not as much as the location, it is also affected by the heat from the heater 10. On the other hand, since the portion in the groove 27 is outside the main body case 2, it is not affected by the heat from the heater 10 and does not hinder the blowing.

一方で、この空気調和装置１は建築物の天井スラブと天井Ｒの間に設置されるが、天井スラブと接触する位置もしくはそれに近い位置に据え付けられることが多く、副取入口１９に空気取入ダクト５５を接続してしまうと、本体ケース２内に配線２８を通す工事が困難になることがある。このような場合も配線２８を溝条２７内に通して側板１２側から側板１３側へ、または側板１３側から側板１２側へと簡単に引き渡すことができる。
また、電気品ボックス２２を側板１３に付け換えた際に、熱交換器３の近傍に配備されている冷媒流量制御装置からの配線２８を側板１２側から側板１３側へ引き渡さなければならないことがある。その場合も冷媒流量制御装置からの配線２８を溝条２７内に通して電気品ボックス２２に接続することができる。
このように、本体ケース２の上面で配線２８を渡すにも拘わらず、熱交換器３の傾斜配置により必然的に生じる内部空間を埋めて形成された溝条２７内に配線２８が収容されるので、市場ニーズである本体ケース２の高さ方向の薄型化を阻害することがない。 On the other hand, although this air conditioning apparatus 1 is installed between the ceiling slab and the ceiling R of the building, it is often installed at a position in contact with or close to the ceiling slab. If the duct 55 is connected, it may be difficult to construct the wiring 28 in the main body case 2. Also in such a case, the wiring 28 can be easily passed from the side plate 12 side to the side plate 13 side or from the side plate 13 side to the side plate 12 side through the groove 27.
Further, when the electrical component box 22 is replaced with the side plate 13, the wiring 28 from the refrigerant flow rate control device arranged in the vicinity of the heat exchanger 3 must be handed over from the side plate 12 side to the side plate 13 side. is there. Also in this case, the wiring 28 from the refrigerant flow control device can be passed through the groove 27 and connected to the electrical box 22.
As described above, the wiring 28 is accommodated in the groove 27 formed by filling the internal space inevitably generated by the inclined arrangement of the heat exchanger 3, although the wiring 28 is passed on the upper surface of the main body case 2. Therefore, the height reduction of the main body case 2 which is a market need is not hindered.

そして、側板１２，１３は、図１０（ａ）に示すように、上辺が曲げ起こされた辺板部３２と、側辺が曲げ起こされた辺板部３３を備えている。辺板部３２には本体ケース２を天井スラブなどから吊り下げるための吊ボルト３１を係止する吊穴２９が設けられている。吊ボルト３１は切欠き部３０を通して吊穴２９に収容される。辺板部３３の上端を折り曲げた折り曲げ部３４が辺板部３２上に重ねられており、ビス挿通穴３５を通したビス３６で折り曲げ部３４と辺板部３２とが固定されている。かかる側板１２，１３の構成により、本体ケース２が補強され一定以上の強度が確保される。これらの側板１２，１３は、曲げ加工、組立工場への搬送、および組立（ネジ締め）を順次経て製品部品とされている。これに対し、図１０（ｂ）に示した従来の側板１２，１３は、辺板部３２と辺板部３３Ａの角隅部が溶接により溶接部３７として固着されており、曲げ加工、溶接工場への搬送、隅肉溶接、組立工場への搬送、および組立（ネジ締め）を順次経て製品部品とされていた。すなわち、手間ひまのかかる、溶接工場への搬送と隅肉溶接の２工程が余分に必要であったため、製造コストと製造時間がかかっていた。そこで、本実施形態のように角隅部分の板金を重ね合わせてビス３６で止めることにより強度を確保することで、溶接工程をなくすことができる。因みに、空気調和装置の組立工程において、ビスによる組立は本体ケースの組立工程のなかに含めることができるが、溶接工程は他に専用の溶接設備および加工工程を設けなければならない。 As shown in FIG. 10A, the side plates 12 and 13 include a side plate portion 32 whose upper side is bent and a side plate portion 33 whose side is bent. The side plate portion 32 is provided with a suspension hole 29 for retaining a suspension bolt 31 for suspending the main body case 2 from a ceiling slab or the like. The suspension bolt 31 is accommodated in the suspension hole 29 through the notch 30. A bent portion 34 obtained by bending the upper end of the side plate portion 33 is overlapped on the side plate portion 32, and the bent portion 34 and the side plate portion 32 are fixed by screws 36 through screw insertion holes 35. With the configuration of the side plates 12 and 13, the main body case 2 is reinforced to ensure a certain level of strength. These side plates 12 and 13 are made into product parts through bending processing, conveyance to an assembly factory, and assembly (screw tightening) in order. On the other hand, in the conventional side plates 12 and 13 shown in FIG. 10B, the corners of the side plate portion 32 and the side plate portion 33A are fixed as welded portions 37 by welding, so that bending work and a welding factory are performed. It was made into a product part through a series of transport, fillet welding, transport to an assembly plant, and assembly (screw tightening). That is, since two extra steps, such as transport to a welding factory and fillet welding, which are time-consuming, are necessary, manufacturing cost and manufacturing time are required. Therefore, as in this embodiment, the welding process can be eliminated by securing the strength by superimposing the sheet metal at the corners and stopping with the screws 36. Incidentally, in the assembling process of the air conditioner, assembly by screws can be included in the assembling process of the main body case, but the welding process must be provided with a dedicated welding facility and processing process.
