Inside the housing 3A, a frame 4 made of a synthetic resin and supported by the frame 4 are provided. A blower 5 composed of a cross flow fan or the like, a heat exchanger 6 which is bent in a substantially rectangular shape and exchanges heat between refrigerant and air, a front frame 7, and a filter 8 supported by the front frame 7. And a drain pan 9 located below the heat exchanger 6. Reference numeral 10 denotes an outlet member, and reference numeral 11 denotes a lower plate of the housing 3A.

そして、前記熱交換器6には、圧縮機、四方弁、室外熱交換器および減圧装置が内蔵された図示しない室外機からの冷媒が供給される。   The heat exchanger 6 is supplied with refrigerant from an outdoor unit (not shown) in which a compressor, a four-way valve, an outdoor heat exchanger, and a pressure reducing device are incorporated.

前記筐体3Aの前面には、図1に示すように、吸込グリル12が配設され、この吸込グリル12の内側に、前記フィルタ8が配設される。そして、吸込グリル12の吸込口12Aから筐体3A内に吸い込まれた被調和室の空気は、フィルタ8で除塵された後に、熱交換器6に至り、ここで空気調和された後に、送風機5を介して吸込グリル12の下部に形成された吹出口12Bから被調和室内に吹き出される。   As shown in FIG. 1, a suction grill 12 is provided on the front surface of the housing 3A, and the filter 8 is provided inside the suction grill 12. Then, the air in the conditioned room sucked into the housing 3A from the suction port 12A of the suction grill 12 is dust-removed by the filter 8, reaches the heat exchanger 6, and is air-conditioned here. The air is blown into the conditioned room from the air outlet 12B formed at the lower part of the suction grille 12 through the opening.

前記筐体3Aの正面視における右端には、前記フレーム4と横並びで、かつ、筐体3Aの縦方向のほぼ一杯に延在する電装箱20が配置されている。   An electrical box 20 is disposed at the right end of the housing 3A in a front view, which is arranged side by side with the frame 4 and extends almost completely in the vertical direction of the housing 3A.

図3は電装箱の正面図であり、図4は電装箱の底面図である。前記電装箱20は樹脂製の電装箱本体21を備え、この電装箱本体21には、その一辺方向Aに沿って一対の制御基板22,23が対向して配置されている。また、前記各制御基板22,23は、電装箱本体21の内壁に形成された凹溝21Aに両縁が差し込まれて、前記電装箱本体21に保持される。   FIG. 3 is a front view of the electrical box, and FIG. 4 is a bottom view of the electrical box. The electric box 20 includes an electric box main body 21 made of resin, and a pair of control boards 22 and 23 are arranged on the electric box main body 21 so as to face each other along a direction A of one side thereof. Each of the control boards 22 and 23 is inserted into a concave groove 21 </ b> A formed on the inner wall of the electric box main body 21, and is held by the electric box main body 21.

前記各制御基板22,23は、互いに対向する面に、電子部品(図示せず)がそれぞれ実装されており、これら電子部品につながるリード線25、26は、各制御基板22,23から延出して、前記電装箱本体21の内側を引き回された後、図3に示すように、電装箱本体21の外側に導出される。   Each of the control boards 22 and 23 has electronic components (not shown) mounted on surfaces facing each other. Lead wires 25 and 26 connected to these electronic components extend from the control boards 22 and 23, respectively. After being drawn around the inside of the electric box main body 21, it is led out of the electric box main body 21 as shown in FIG. 3.

また、前記電装箱本体21内には、その電装箱本体21の一辺に隣接する他辺方向Bに沿って、端子台28が配置され、この端子台28には、前記各制御基板22,23及び電源線(図示せず)が接続される。そして、前記端子台28と電装箱本体21との間には、図4に示すように、その電装箱本体21の内側と外側を連通する溝部29が形成されている。具体的には、電装箱本体21の外壁に略U字状の溝部29が形成され、この溝部29を跨ぐように上述した端子台28が配置されており、そして、この端子台28は、前記溝部29と対応する位置の電装箱本体21に配置されている。   In the electrical box main body 21, a terminal block 28 is disposed along the other side direction B adjacent to one side of the electrical box main body 21, and the terminal board 28 is provided with the control boards 22 and 23. And a power supply line (not shown). As shown in FIG. 4, a groove 29 is formed between the terminal block 28 and the electrical box main body 21 to communicate the inside and the outside of the electrical box main body 21. Specifically, a substantially U-shaped groove portion 29 is formed on the outer wall of the electrical box main body 21, and the above-described terminal block 28 is disposed so as to straddle the groove portion 29. It is disposed on the electrical box main body 21 at a position corresponding to the groove 29.

本実施例では、電子部品(図示せず)につながるリード線25、26は、前記電装箱本体21の内側を引き回された後、端子台28で囲われた溝部29に挿通させて、電装箱本体21の外側に導出される。そして、前記溝部29の大きさを、リード線25、26を通すだけの大きさに形成することにより、前記溝部29に挿通された前記リード線25、26は、前記端子台28によって上から押さえつけられるため、溝部29内にしっかりと固定される。   In the present embodiment, the lead wires 25 and 26 connected to the electronic components (not shown) are routed inside the electrical box main body 21 and then inserted into the groove 29 surrounded by the terminal block 28 so that the electrical components are It is led out of the box body 21. Then, by forming the size of the groove portion 29 to be large enough to allow the lead wires 25 and 26 to pass through, the lead wires 25 and 26 inserted into the groove portion 29 are pressed down from above by the terminal block 28. Therefore, it is firmly fixed in the groove 29.

これによれば、従来のように、リード線を、電装箱本体の一端から外側に引き出し、この電装箱本体の外壁に沿って引き回して、電装箱本体の他端に設置された接続のためのスペースに導く必要がない。即ち、その接続スペースは、図3に示すように、端子台28の下方に位置して、電装箱本体21の外部に形成されるスペースSであり、このスペースSには、例えば、送風機5のモータにつながるリード線や、吸込温度センサ等のセンサ類につながるリード線が導かれ、この位置で、各リード線と上記リード線25、26とがコネクタ結合される。   According to this, as in the related art, the lead wire is drawn out from one end of the electrical box main body, and routed along the outer wall of the electrical box main body, for connection provided at the other end of the electrical box main body. There is no need to lead to space. That is, as shown in FIG. 3, the connection space is a space S located below the terminal block 28 and formed outside the electrical box main body 21. A lead wire connected to the motor and a lead wire connected to sensors such as a suction temperature sensor are guided, and at this position, each lead wire and the above-described lead wires 25 and 26 are connected by a connector.

本実施例では、リード線25、26が、電装箱本体21の内側を通り、溝部29を通じて、電装箱本体21の外側に導出されるため、従来のように、電装箱本体21の外側を引き回すものと比べ、まとまり良く配線できるとともに、リード線を束ねるための余分な止め具が不要になり、配線接続作業の効率化を図ることができる等の効果が得られる。   In this embodiment, since the lead wires 25 and 26 pass through the inside of the electrical box main body 21 and are led out of the electrical box main body 21 through the grooves 29, the outside of the electrical box main body 21 is routed as in the related art. Compared to the case, the wires can be arranged in a more coherent manner, and an extra stopper for bundling the lead wires is not required, so that effects such as an increase in the efficiency of the wiring connection work can be obtained.

以上、一実施例に基づいて本発明を説明したが、本発明は、これに限定されるものではなく、種々変更が可能である。   As described above, the present invention has been described based on one embodiment. However, the present invention is not limited to this, and various modifications can be made.
