Description

本発明は、組立性の向上と送風効率の向上を図ったダクト型空気調和機の室内機に関する。   The present invention relates to an indoor unit of a duct type air conditioner that is improved in assemblability and air blowing efficiency.

従来のダクト型空気調和機の室内機として、たとえば図12〜図14に示すように、その室内機本体200の内部構成を、吹出ダクト取付枠211を有する前面板212の内側にモータ221で駆動される送風装置220を取り付け、吸込ダクト取付枠213を有する背面板214の内側に熱交換器230を配置し、電装品室240を室内機本体200の側面板215の外壁面に配置し、その側面板215に配管接続口231を引き出し、その部分を配管カバー216で覆ったものがある(特許文献1)。   As an indoor unit of a conventional duct type air conditioner, for example, as shown in FIGS. 12 to 14, the internal configuration of the indoor unit body 200 is driven by a motor 221 inside a front plate 212 having a blowout duct mounting frame 211. The air blower 220 is attached, the heat exchanger 230 is arranged inside the back plate 214 having the suction duct attachment frame 213, the electrical component chamber 240 is arranged on the outer wall surface of the side plate 215 of the indoor unit body 200, There is one in which a pipe connection port 231 is drawn out to a side plate 215 and the part is covered with a pipe cover 216 (Patent Document 1).

特開2004−204810号公報JP 2004-204810 A

ところが、特許文献1にあるように、室内機本体200の内部を1つの部屋で構成した場合は、室内機本体の筐体は四方の板金だけで構成されることになるため、大型の空気調和機ともなると、送風装置220のモータ221や熱交換器230が大型となることから、これを支持するための筐体の強度が不十分となる。特に、前面板212にはその内側に送風装置220を直接取り付けるため、その送風装置220の重さで前面板212がたわむことがある。また、吸い込まれた空気の一部は熱交換器230の横の配管周り(図示せず)を通過する際に配管が抵抗となり、送風効率が低下し、さらに、本体内に電装品室240を配置する場合(図示せず)は、吸い込まれた空気の一部が電装品室240の廻りを通過するため、電装品室240が冷やされて結露するなどの問題があった。   However, as disclosed in Patent Document 1, when the interior of the indoor unit main body 200 is configured as a single room, the casing of the indoor unit main body is configured by only four-sided sheet metal. If it becomes a machine, since the motor 221 of the air blower 220 and the heat exchanger 230 will be large, the intensity | strength of the housing | casing for supporting this will become inadequate. In particular, since the air blower 220 is directly attached to the inner side of the front plate 212, the front plate 212 may be bent by the weight of the air blower 220. Further, when a part of the sucked air passes around the pipe (not shown) beside the heat exchanger 230, the pipe becomes a resistance, the blowing efficiency is lowered, and the electrical component chamber 240 is installed in the main body. In the case of arrangement (not shown), a part of the sucked air passes around the electrical component chamber 240, which causes a problem that the electrical component chamber 240 is cooled and condensed.

本発明の目的は、筐体に十分な強度を確保でき、また送風効率が低下せず、電装品室が結露することもないようにしたダクト型空気調和機の室内機を提供することである。   An object of the present invention is to provide an indoor unit of a duct-type air conditioner that can secure sufficient strength in a casing, that air blowing efficiency does not decrease and that an electrical component room does not condense. .

上記目的を達成するために、請求項1にかかる発明は、少なくとも、吹出口を有する前面板と、吸込口を有する背面板と、底面板を兼ねるセーフティドレンパンと、全体の上面を覆う天板と、前記前面板の片端と前記背面板の片端を接続する側面板とで筐体を構成し、前記前面板の裏面に送風装置を固定し、前記背面板の裏面に熱交換器を配置して、室内機本体を構成したダクト型空気調和機の室内機において、前記筐体内を左右に区画する仕切板を設け、前記仕切板の片端を前記前面板の裏面に固定したことを特徴とする。
請求項2にかかる発明は、請求項1に記載のダクト型空気調和機の室内機において、前記熱交換器の配管出口側に前記熱交換器を縦姿勢に保持させるための熱交側板を配置し、該熱交側板の一端を前記背面板に固定し、前記熱交側板の他端と前記仕切板の他端を相互に固定して前記熱交側板と前記仕切板を一列に立設して区画壁とし、前記区画壁で区画された一側に前記送風装置および前記熱交換器を配置する送風室を形成し、前記区画壁で区画された他側に電装品室と配管室を形成したことを特徴とする。
請求項3にかかる発明は、請求項2に記載のダクト型空気調和機の室内機において、前記送風装置は、一方に前記前面板の前記吹出口の裏面に配置された送風ファンを、他方に前記送風ファンを回転させるモータを備え、前記仕切板は、前記送風装置の前記モータの側に偏った位置に固定したことを特徴とする。
To achieve the above object, the invention according to claim 1 includes at least a front plate having an air outlet, a back plate having a suction port, a safety drain pan also serving as a bottom plate, and a top plate covering the entire top surface. A casing is composed of one end of the front plate and a side plate connecting one end of the back plate, a blower is fixed to the back surface of the front plate, and a heat exchanger is disposed on the back surface of the back plate. In the indoor unit of a duct type air conditioner that constitutes the indoor unit main body, a partition plate that divides the inside of the housing into right and left is provided, and one end of the partition plate is fixed to the back surface of the front plate.
According to a second aspect of the present invention, in the indoor unit of the duct-type air conditioner according to the first aspect, a heat exchange side plate for holding the heat exchanger in a vertical posture is arranged on a pipe outlet side of the heat exchanger. One end of the heat exchange side plate is fixed to the back plate, the other end of the heat exchange side plate and the other end of the partition plate are fixed to each other, and the heat exchange side plate and the partition plate are erected in a row. Forming a blower chamber in which the blower and the heat exchanger are arranged on one side partitioned by the partition wall, and forming an electrical component chamber and a piping chamber on the other side partitioned by the partition wall It is characterized by that.
According to a third aspect of the present invention, in the indoor unit of the duct type air conditioner according to the second aspect, the blower device has a blower fan disposed on the back surface of the blower outlet of the front plate on the one side. A motor for rotating the blower fan is provided, and the partition plate is fixed at a position biased toward the motor of the blower.

本発明によれば、室外機本体の筐体内を左右に区画する仕切板を設け、その仕切板の片端を前面板の裏面に固定したことにより、筐体の強度が増す。また、仕切板の片端を前面板の裏面に固定したことにより、前面板に送風装置を組み付けてから天板を組み立てる際に、送風装置を組み付けた前面板を縦姿勢にさせることができ、組立作業が容易となる効果がある。また、仕切板と熱交側板を一列に立設して区画壁を構成し、その区画壁の一列立設の一側に送風装置および熱交換器を配置する送風室を形成し、他側に電装品室と配管室を形成することにより、送風装置には熱交換器を通過した後の空気だけが吸い込まれるので、送風効率が高くなるとともに、電装品室が送風によって冷やされることがなく、そこに結露が生じることを防止できる。さらに、仕切板を送風装置のモータの側に偏った位置に固定することで、前面板がその送風装置の重量でゆがむことを防止できる。   According to the present invention, the strength of the housing is increased by providing the partition plate that divides the housing of the outdoor unit main body into the left and right sides, and fixing one end of the partition plate to the back surface of the front plate. In addition, by fixing one end of the partition plate to the back surface of the front plate, when assembling the top plate after assembling the blower device on the front plate, the front plate with the blower device assembled can be placed in a vertical position. There is an effect that the work becomes easy. Moreover, the partition plate and the heat exchange side plate are erected in a row to form a partition wall, and a blower chamber in which the blower and the heat exchanger are arranged on one side of the partition wall is formed on the other side. By forming the electrical component chamber and the piping chamber, only the air after passing through the heat exchanger is sucked into the blower device, so that the blowing efficiency is increased and the electrical component chamber is not cooled by blowing, Condensation can be prevented from occurring there. Furthermore, it is possible to prevent the front plate from being distorted by the weight of the blower by fixing the partition plate at a position biased toward the motor of the blower.

Reference numeral 1 denotes an indoor unit main body. One end of a suction duct 2A is attached to the suction port 1a, and the other end of the suction duct 2A communicates with the indoor space 4 by a suction grill 3A. In addition, one end of the blowout duct 2B is attached to the blowout port 1b of the indoor unit body 1, and the other end of the blowout duct 2B is communicated with the indoor space 4 by the blowout grill 3B. The indoor unit body 1 is placed on the ceiling plate 6 of the building in the ceiling space 5. The indoor unit body 1 may be hung from the building ceiling.

室内機本体1は、図2および図3に示すように、底面板を兼ねるセーフティドレンパン101と、吹出口1bを備えた前面板102と、吸込口1aを備えた背面板103と、前面板102と背面板103をつなぐ左側の側面板104と、天板105によって、その筐体が構成されている。前面板102と、背面板103と、側面板104と、前面板102に取り付けられる仕切板106は、セーフティドレンパン101から立設し、筐体骨組αを形成している。セーフティドレンパン101は、筐体骨組αより一回り大きく、本体内の水を外部に漏らさないように周囲に枠101aを備えている。この枠101aと前面板102及び背面板103とを固定することで、筐体骨組αにセーフティドレンパン101が取り付けられている。そして、前面板102には吹出ダクト2Bを取り付ける吹出ダクト取付枠108が設けられ、背面板103には吸込ダクト2Aを取り付ける吸込ダクト取付枠107が設けられている。   As shown in FIGS. 2 and 3, the indoor unit main body 1 includes a safety drain pan 101 that also serves as a bottom plate, a front plate 102 that includes an air outlet 1b, a back plate 103 that includes a suction port 1a, and a front plate 102. The left side plate 104 that connects the rear plate 103 and the top plate 105 constitute a housing. The front plate 102, the back plate 103, the side plate 104, and the partition plate 106 attached to the front plate 102 are erected from the safety drain pan 101 to form a housing frame α. The safety drain pan 101 is slightly larger than the housing frame α, and includes a frame 101a around the body so as not to leak water in the main body to the outside. The safety drain pan 101 is attached to the housing frame α by fixing the frame 101 a to the front plate 102 and the back plate 103. The front plate 102 is provided with a blowing duct mounting frame 108 for mounting the blowing duct 2B, and the back plate 103 is provided with a suction duct mounting frame 107 for mounting the suction duct 2A.

室内機本体1の内部は、図3に示すように、仕切板106と後述する熱交側板141を一列に立設することによって区画壁βを構成し、その区画壁βで区画された一側が送風室120となり、他側が電装品室130と配管室160となる。仕切板106は、図5〜図8、図10に示すように、前面板102の裏面に、側面板104と並行な向きでその前面板102に直交するように、つまり上面から見てT字形状に片端が固定され、筐体内を左右に区画している。そして、電装品室130と配管室160は、その電装品室130の電装品室背面板131によって区画されている。送風室120内には、前面板102の吹出口1bの背面に送風装置150が直接取り付けられ、背面板103の近傍に熱交換器140が縦姿勢で配置されている。この構成により、送風装置150によって吸込口1aから吸い込まれる空気は、室内空間4から吸込グリル3Aと吸込ダクト2Aを通り、熱交換器140で熱交換された後、吹出口1bから吹出ダクト2Bと吹出ダクト3Bを通過して、室内空間4に吹き出される。   As shown in FIG. 3, the interior of the indoor unit main body 1 includes a partition wall 106 and a heat exchange side plate 141 (described later) arranged in a row to form a partition wall β, and one side partitioned by the partition wall β is The blower chamber 120 is provided, and the other side is the electrical component chamber 130 and the piping chamber 160. As shown in FIGS. 5 to 8 and 10, the partition plate 106 is formed in a T-shape on the back surface of the front plate 102 so as to be orthogonal to the front plate 102 in a direction parallel to the side plate 104. One end is fixed to the shape, and the inside of the housing is divided into left and right. The electrical component chamber 130 and the piping chamber 160 are partitioned by an electrical component chamber back plate 131 of the electrical component chamber 130. In the blower chamber 120, the blower 150 is directly attached to the back surface of the air outlet 1 b of the front plate 102, and the heat exchanger 140 is disposed in a vertical posture in the vicinity of the back plate 103. With this configuration, the air sucked from the suction port 1a by the blower 150 passes through the suction grill 3A and the suction duct 2A from the indoor space 4 and is heat-exchanged by the heat exchanger 140, and then from the blower outlet 1b to the blowout duct 2B. It passes through the blowing duct 3B and is blown into the indoor space 4.

熱交換器140は、筐体骨組αに固定するための熱交側板141を備えており、この熱交側板141の一方を仕切板106に、他方を背面板103に取付けることで、筐体骨組αに固定される。送風装置150は、回転軸151に送風ファン152を2台結合して構成され、回転軸151の片端にはモータ支持具153で支持されたモータ154を備え、他端には軸固定台155で支持された軸受具156を備える。送風ファン152は、送風ファン152を囲い、それぞれ上下に分割でき、前面板102の吹出口1b内に開口するファンケーシング157を備える。モータ支持具153は、前面板102に取り付けるための取付基台158を備える。送風装置150は、軸固定台155、ファンケーシング157、取付基台158を前面板102に取り付けることで、前面板102に固定されている。   The heat exchanger 140 includes a heat exchange side plate 141 for fixing to the housing frame α. By attaching one of the heat exchange side plates 141 to the partition plate 106 and the other to the back plate 103, the frame of the housing is obtained. It is fixed to α. The blower 150 is configured by connecting two blower fans 152 to a rotary shaft 151, and includes a motor 154 supported by a motor support 153 at one end of the rotary shaft 151, and a shaft fixing base 155 at the other end. A supported bearing 156 is provided. The blower fan 152 includes a fan casing 157 that surrounds the blower fan 152 and can be divided into upper and lower parts and opens into the air outlet 1b of the front plate 102. The motor support 153 includes an attachment base 158 for attaching to the front plate 102. The blower 150 is fixed to the front plate 102 by attaching the shaft fixing base 155, the fan casing 157, and the mounting base 158 to the front plate 102.

この送風装置150を組み立てる際は、まず、前面板102に対し、表面(本体外側)に、吹出ダクト取付枠108を、裏面(本体内側)に、仕切板106、軸固定台155、モータ支持具153を固定した取付基台158等を、それぞれ固定する。次に、前面板102の表面を底にして、モータ154、ファンケーシング157、軸受具156、回転軸151等を、それぞれ所定の位置に合わせて固定する。このとき、モータ154は、前面板102に対して、仕切板106の側に偏った位置に取り付けられる。そして、図6に示すように、天地を逆さにした天板105の上に、前面板102を起こす。天板105は、その天板105の補強および筐体骨組αを固定するための天板枠105aを備えている。この天板枠105aに前面板102を固定する。   When assembling the blower 150, first, with respect to the front plate 102, the blowing duct mounting frame 108 is provided on the front surface (outside the main body), and the partition plate 106, the shaft fixing base 155, and the motor support on the back surface (inside the main body). The mounting base 158 to which the 153 is fixed is fixed. Next, with the surface of the front plate 102 as the bottom, the motor 154, the fan casing 157, the bearing tool 156, the rotating shaft 151, and the like are fixed to predetermined positions. At this time, the motor 154 is attached to a position biased toward the partition plate 106 with respect to the front plate 102. Then, as shown in FIG. 6, the front plate 102 is raised on the top plate 105 that is upside down. The top plate 105 includes a top plate frame 105a for reinforcing the top plate 105 and fixing the housing frame α. The front plate 102 is fixed to the top plate frame 105a.

このときは、まだ、側面板104は取り付けられていないため、前面板102は天板105の天板枠105aと固定されただけとなり、前面板102の裏面に取り付けられた重量の大きな送風装置150の影響により不安定となる可能性があるが、前面板102に対して上面から見てT字形状となるように仕切板106の片端が固定されているので、仕切板106が天板105で支持され、前面板102は安定して起きた状態を維持できる。さらに、仕切板106は、送風装置150のうち、最も重量が大きいモータ154側に偏った位置に取り付けているので、前面板102の荷重は仕切板106にバランスよくかかり、安定して縦姿勢を維持できる。同様に、背面板103に対し、表面(本体外側)に吸込ダクト取付枠107を、裏面(本体内側)に熱交換器140を取り付ける。熱交換器140は、その熱交換器140に備えられた熱交側板141の一側を背面板103に固定することで取り付けられる。前面板102が取り付けられた天板105内に背面板103を配置し、天板枠105aに背面板103を固定する。次に、熱交側板141の他側を仕切板106の前面板102と固定されない側に固定する。さらに、前面板102と背面板103を繋ぐように、側面板104を取り付け、続いて後述する電装品室130を構成する部材を取り付け、最後にセーフティドレンパン101を被せて取付けることにより、組立が完了する。   At this time, since the side plate 104 is not yet attached, the front plate 102 is only fixed to the top plate frame 105a of the top plate 105, and the heavy air blower 150 attached to the back surface of the front plate 102 is used. Although one end of the partition plate 106 is fixed to the front plate 102 so as to be T-shaped when viewed from the top, the partition plate 106 is a top plate 105. The front plate 102 is supported and can maintain a stable state. Furthermore, since the partition plate 106 is attached to a position biased toward the motor 154 having the largest weight in the blower 150, the load on the front plate 102 is applied to the partition plate 106 in a well-balanced manner and takes a stable vertical posture. Can be maintained. Similarly, the suction duct attachment frame 107 is attached to the front surface (outside the main body) and the heat exchanger 140 is attached to the rear surface (inside the main body). The heat exchanger 140 is attached by fixing one side of the heat exchange side plate 141 provided in the heat exchanger 140 to the back plate 103. The back plate 103 is disposed in the top plate 105 to which the front plate 102 is attached, and the back plate 103 is fixed to the top plate frame 105a. Next, the other side of the heat exchange side plate 141 is fixed to the side of the partition plate 106 that is not fixed to the front plate 102. Further, the side plate 104 is attached so as to connect the front plate 102 and the back plate 103, then a member constituting the electrical component chamber 130 described later is attached, and finally the safety drain pan 101 is attached, and the assembly is completed. To do.

このように、組立途中では図6に示したように、送風装置150が仕切板106によって支えられるため、その他の部品の取り付けをスムーズに行うことができ、組立性が向上する。また、熱交側板141と仕切板106を一列に繋ぐことで、送風室120が電装品室130および配管室160から分離されているので、送風が電装品室130や配管等の影響をうけることがなく、送風効率が向上し、吸い込んだ空気によって電装品室130が冷やされて結露することがない。   In this way, as shown in FIG. 6, the air blower 150 is supported by the partition plate 106 during the assembly, so that other components can be attached smoothly and the assemblability is improved. In addition, since the blower chamber 120 is separated from the electrical component chamber 130 and the piping chamber 160 by connecting the heat exchange side plate 141 and the partition plate 106 in a row, the blower is affected by the electrical component chamber 130, the piping, and the like. The air blowing efficiency is improved, and the electrical component chamber 130 is not cooled by the sucked air and does not condense.

電装品室130は、図7〜図10で示すように、2方を囲うように立設された平面L字形状の一片の電装品室背面板131と他片の電装品室側板132と、その開放した一方の面(電装品室側板132の対面)を外部に対して閉じる電装品室蓋133と、他方の面(前面)を覆う前面板102の一部とで周囲が閉じられ、天板105の一部で上面が閉じられ、底面が上げ底(図9参照)の電装品室底面板134で閉じられた構成となっている。そして、電装品室側板132と仕切板106の間に装着された電装品室取付具135により、電装品室側板132と仕切板106が並列配置され、その間に間隔Xが形成されている(図7参照)。そして、電装品室130の内部にはリアクタ136やコンデンサ137やその他の電装品が取り付けられている(図8参照)。なお、リアクタ136やコンデンサ137は、前面板102とは逆の上方角部に配置されている。   As shown in FIGS. 7 to 10, the electrical component chamber 130 is composed of a plane L-shaped piece of electrical component chamber back plate 131 and another piece of electrical component chamber side plate 132 erected so as to surround two sides. The electric component chamber lid 133 that closes one of the opened surfaces (facing the electric component chamber side plate 132) with respect to the outside and a part of the front plate 102 that covers the other surface (front surface) close the periphery. The upper surface is closed by a part of the plate 105, and the bottom surface is closed by an electrical component chamber bottom plate 134 having a raised bottom (see FIG. 9). Then, the electrical component chamber side plate 132 and the partition plate 106 are arranged in parallel by the electrical component chamber mounting tool 135 mounted between the electrical component chamber side plate 132 and the partition plate 106, and an interval X is formed therebetween (see FIG. 7). A reactor 136, a capacitor 137, and other electrical components are attached inside the electrical component chamber 130 (see FIG. 8). The reactor 136 and the capacitor 137 are arranged at the upper corner opposite to the front plate 102.

この構成により、仕切板106の送風室120側の電装品室130近傍は熱交換された空気が流れており、電装品室130にはリアクタ136やコンデンサ137等の発熱部品があるため、送風室120と電装品室130には温度差があり、仕切板106に露が発生する場合もあるが、その場合は、仕切板106の電装品室130の側に露が付き、仕切板106についた露はセーフティドレンパン101に流れる。一方、電装品室130は、仕切板106から間隔Xだけ離れているため、送風室120および仕切板106の温度の影響を受けず、電装品室130の外側に露が発生することはない。また、電装品室130が上げ底となっているため、セーフティドレンパン101に露が溜まっても、電装品への影響は無い。   With this configuration, heat-exchanged air flows in the vicinity of the electrical component chamber 130 on the side of the blower chamber 120 of the partition plate 106, and the electrical component chamber 130 includes heat generating components such as the reactor 136 and the capacitor 137. There is a temperature difference between 120 and the electrical component chamber 130, and dew may be generated in the partition plate 106. In this case, dew is attached to the electrical component chamber 130 side of the partition plate 106, and the partition plate 106 is attached. The dew flows into the safety drain pan 101. On the other hand, since the electrical component chamber 130 is separated from the partition plate 106 by the interval X, the electrical component chamber 130 is not affected by the temperature of the blower chamber 120 and the partition plate 106, and dew does not occur outside the electrical component chamber 130. In addition, since the electrical component chamber 130 is raised, even if dew accumulates in the safety drain pan 101, the electrical component is not affected.

また、図10に示すように、電装品室130の電装品室側板132には、リアクタ136やコンデンサ137の近傍に電装品室通孔132aが形成され、その電装品室通孔132aと対応する仕切板106の位置にも、図5に示すように、仕切板通孔106aが形成されている。さらに、上げ底の電装品室底面板134には、セーフティドレンパン101の枠101aに対向する上げ底側面に、電装品室蓋133によって閉塞されることがない切欠きによる空気取入口134aが形成されている。なお、この電装品室底面板134は、電装品室側板132の前後幅よりも狭く形成され、このため、図10に示すように、前面板102の裏面と電装品室底面板134との間で電装品室130の下方角部に隙間G1が形成されている。また、セーフティドレンパン101は筐体骨組αよりも大きいため、セーフティドレンパン101の枠101aと電装品室蓋133との間に隙間G2が形成されている。   As shown in FIG. 10, the electrical component chamber side plate 132 of the electrical component chamber 130 has an electrical component chamber through hole 132a in the vicinity of the reactor 136 and the capacitor 137, and corresponds to the electrical component chamber through hole 132a. As shown in FIG. 5, a partition plate through hole 106 a is also formed at the position of the partition plate 106. Further, the raised bottom electrical component chamber bottom plate 134 is formed with a notch air intake 134 a that is not blocked by the electrical component chamber lid 133 on the raised bottom side surface facing the frame 101 a of the safety drain pan 101. . The electrical component chamber bottom plate 134 is formed to be narrower than the front and rear width of the electrical component chamber side plate 132. Therefore, as shown in FIG. 10, the electrical component chamber bottom plate 134 is located between the back surface of the front plate 102 and the electrical component chamber bottom plate 134. Thus, a gap G1 is formed in the lower corner of the electrical component chamber 130. Further, since the safety drain pan 101 is larger than the housing frame α, a gap G2 is formed between the frame 101a of the safety drain pan 101 and the electrical component chamber lid 133.

この構成により、送風装置150によって吸い込まれる天井裏内の空気は、セーフティドレンパン101の枠101aと電装品室蓋133との隙間G2から、電装品室底面板134の空気取入口134aに入り込み、その電装品室底面板134の下面とセーフティドレンパン101との間を通り、前面板102との隙間G1から電装品室130内に入り、電装品室側板132の電装品室通孔132a、仕切板106の同様な仕切板通孔106aを通過し、送風室120の送風装置150の送風ファン152に吸引される。この結果、電装品室130内に、図10に矢印で示すように、前面板102側の下方角部から前面板102と逆側の上方角部に向かう空気通路が形成され、電装品室130内の全体が効果的に冷却される。また、発熱部品であるリアクタ136やコンデンサ137は空気通路の出口である電装品室通孔132aの近傍に配置されているため、リアクタ136やコンデンサ137で発生した熱は、電装品室130内には流れず、そのまま電装品室通孔132aから出ることになり、他の部品に影響を与えることがない。   With this configuration, the air in the ceiling behind the air sucked by the blower 150 enters the air intake port 134a of the electrical component chamber bottom plate 134 from the gap G2 between the frame 101a of the safety drain pan 101 and the electrical component chamber lid 133, It passes between the lower surface of the electrical component room bottom plate 134 and the safety drain pan 101, enters the electrical component chamber 130 through the gap G1 with the front plate 102, and passes through the electrical component chamber through-hole 132a of the electrical component chamber side plate 132 and the partition plate 106. It passes through the same partition plate through hole 106a and is sucked by the blower fan 152 of the blower 150 of the blower chamber 120. As a result, an air passage from the lower corner on the front plate 102 side to the upper corner on the opposite side of the front plate 102 is formed in the electric component chamber 130 as indicated by an arrow in FIG. The whole inside is cooled effectively. In addition, since the reactor 136 and the capacitor 137 that are heat generating components are disposed in the vicinity of the electrical component chamber through-hole 132a that is the outlet of the air passage, the heat generated in the reactor 136 and the capacitor 137 enters the electrical component chamber 130. Will not flow and will exit from the electrical component chamber through-hole 132a without affecting other parts.

熱交換器140は、セーフティドレンパン101に縦姿勢で配置されている。熱交換器140の配管出口側を支える熱交側板141は、一側を背面板103に固定され、他側を仕切板106に固定されている。また、熱交換器140は、その熱交換器140の底面とセーフティドレンパン101との間に熱交換器140の露を受けるドレンパン142を備え、このドレンパン142は熱交側板141の下を通って配管室160内まで配置され、配管室160の配管の露受けを兼ねている。   The heat exchanger 140 is arranged in a vertical posture on the safety drain pan 101. The heat exchange side plate 141 that supports the pipe outlet side of the heat exchanger 140 has one side fixed to the back plate 103 and the other side fixed to the partition plate 106. The heat exchanger 140 includes a drain pan 142 that receives dew from the heat exchanger 140 between the bottom surface of the heat exchanger 140 and the safety drain pan 101, and the drain pan 142 passes under the heat exchange side plate 141 and is piped. It arrange | positions to the inside of the chamber 160, and doubles as the dew receiving of the piping of the piping chamber 160.

さらに、配管室160は、熱交換器140の配管部分を内包するように、熱交側板141と、その熱交側板141と一列に繋がれた仕切板106の一部と、電装品室130の電装品室背面板131と、背面板103の一部とで周囲が囲まれることで形成されている。この配管室160の開放面(側面)には、図10および図11に示すように、着脱自在の配管室蓋161が取り付けられる。また、配管室蓋161には、メンテナンス用に開口161aが設けられていて、着脱自在の配管カバー162で閉じられるようになっている。さらに、配管室160内には、熱交換器140から伸びる冷媒配管163、サーミスタ(図示せず)、電子膨張弁(図示せず)等が配置されている。サーミスタは、棒形状であって、銅板を折り曲げて形成した筒形状のサーミスタ取付カバー164内に挿入されており、冷媒配管163の冷媒温度を正確に検知できるように、その冷媒配管163にサーミスタ取付カバー164によって取り付けられている。そして、室外機に対して冷媒を導出/導入する熱交換器140の外部接続配管165は、配管室蓋161および配管カバー162の切欠き部161b,162aを通って外部に引き出されている。   Furthermore, the piping chamber 160 includes a heat exchange side plate 141, a part of the partition plate 106 connected in a row with the heat exchange side plate 141, and the electrical component chamber 130 so as to include the piping portion of the heat exchanger 140. The electrical component room back plate 131 and a part of the back plate 103 are surrounded by the periphery. As shown in FIGS. 10 and 11, a detachable piping chamber lid 161 is attached to the open surface (side surface) of the piping chamber 160. The piping chamber lid 161 is provided with an opening 161a for maintenance, and is closed by a detachable piping cover 162. Further, in the piping chamber 160, a refrigerant pipe 163 extending from the heat exchanger 140, a thermistor (not shown), an electronic expansion valve (not shown), and the like are arranged. The thermistor has a rod shape and is inserted into a cylindrical thermistor mounting cover 164 formed by bending a copper plate. The thermistor is attached to the refrigerant pipe 163 so that the refrigerant temperature of the refrigerant pipe 163 can be accurately detected. A cover 164 is attached. And the external connection piping 165 of the heat exchanger 140 that leads / introduces the refrigerant to / from the outdoor unit is drawn out through the piping chamber lid 161 and the notches 161b and 162a of the piping cover 162.

これにより、送風室120や電装品室130と区切られた配管室160内のサーミスタ取付カバー164内のサーミスタは、熱交側板141とその熱交側板141と一列に繋がれた仕切板106とにより送風室120から遮蔽されているため、熱交換器140を通る空気の影響を受けず、また、電装品室130と配管室160を区切る電装品室背面板131は、熱交側板141とその熱交側板141と一列に繋がれた仕切板106の繋ぎ目ではなく、仕切板106側に配置されているため、電装品室130の温度の影響を受けることもなく、冷媒配管163を流れる冷媒温度を正確に検知する。また、背面板103の吸込口1aから取り込まれて送風室120に至る空気は、配管室160の影響を受けずに、熱交換器140を通過した空気だけとなるため、効率のよい送風が可能となる。また、配管室蓋161は、天板105の側面や電装品室蓋133の上からネジ等で固定される(図11)ので、配管のメンテナンス時には、配管室蓋161の取り外し/取り付けが簡単となり、メンテナンスの作業性が向上する。また、配管室蓋161は、天板105の下に差し込むように構成することでも、同様な効果を得ることができる。   As a result, the thermistor in the thermistor mounting cover 164 in the piping chamber 160 separated from the blower chamber 120 and the electrical component chamber 130 includes the heat exchange side plate 141 and the partition plate 106 connected to the heat exchange side plate 141 in a row. Since it is shielded from the air blowing chamber 120, it is not affected by the air passing through the heat exchanger 140, and the electrical component room back plate 131 that separates the electrical component chamber 130 and the piping chamber 160 is the heat exchange side plate 141 and its heat. The temperature of the refrigerant flowing through the refrigerant pipe 163 is not affected by the temperature of the electrical component chamber 130 because it is arranged on the side of the divider plate 106 instead of the joint of the divider plate 106 connected to the intersection plate 141 in a row. Is detected accurately. In addition, the air that is taken in from the suction port 1a of the back plate 103 and reaches the blower chamber 120 is only the air that has passed through the heat exchanger 140 without being affected by the piping chamber 160, so efficient air blowing is possible. It becomes. Further, since the piping chamber lid 161 is fixed with screws or the like from the side surface of the top plate 105 or the electrical component chamber lid 133 (FIG. 11), the piping chamber lid 161 can be easily removed / attached during maintenance of the piping. Maintenance workability is improved. The piping chamber lid 161 can be configured to be inserted under the top plate 105 to obtain the same effect.
