Description

本発明は空気調和機に係り、特に熱交換器の構造を改良した空気調和機に関する。   The present invention relates to an air conditioner, and more particularly to an air conditioner having an improved heat exchanger structure.

このような室内熱交換器は分割熱交換器を所定位置に保持するために多くの取付部品を必要とし、また、隣接する分割熱交換器が接続される折曲部に間隙が生じ、この隙間から放熱フィン間を通らない空気が、通気路中に流入し、送風機、通気路あるいはその周辺で結露を生じさせる。また、放熱フィン間を通過する空気と隙間から流入する空気では、流速が異なるため、異常音の発生原因になる。   Such an indoor heat exchanger requires many mounting parts to hold the divided heat exchanger in a predetermined position, and a gap is formed in a bent portion to which an adjacent divided heat exchanger is connected. The air that does not pass between the heat radiating fins flows into the air passage and causes condensation in the blower, the air passage or in the vicinity thereof. Moreover, since the flow velocity differs between the air passing between the radiating fins and the air flowing in through the gap, it may cause abnormal noise.

さらに、シール部材を取り付けても、部品精度や組立精度のバラツキにより、隙間を塞ぎきれない場合があり、シール部材の確実な固定が必要であり、固定用に多くの取付部品を要し、高価になる。   Furthermore, even if the seal member is installed, the gap may not be closed due to variations in component accuracy and assembly accuracy, and the seal member must be securely fixed, requiring many mounting parts for fixing, and expensive. become.

なお、略逆V字形状に前後に隣接する熱交換器間に形成される間隙に遮風板を設け、この遮風板を支持部材で固定し、さらに、この支持部材を熱交換器の両端に設けた側板に固定する空気調和機が提案されている(例えば、特許文献1参照)。この特許文献1に記載のものは、前後に配置される熱交換器を左右の端板を含めて別個に製造し、それらを支持板と遮風板を前後から挟み込むように一体的に結合して固定しているため、固定用に多くの取付部品を要する。
特開2003−240332号公報
In addition, a windshield is provided in a gap formed between the heat exchangers adjacent to each other in a substantially reverse V shape, and the windshield is fixed by a support member. Further, the support member is fixed to both ends of the heat exchanger. There has been proposed an air conditioner that is fixed to a side plate that is provided on the side plate (see, for example, Patent Document 1). The one described in this Patent Document 1 separately manufactures heat exchangers arranged at the front and rear, including the left and right end plates, and integrally couples them so as to sandwich the support plate and the wind shield plate from the front and rear. Therefore, many mounting parts are required for fixing.

さらに、隙間G、G部分により第1、第2の熱交換器固定具11、12を各金属製端板71a、72a、73aと樹脂製端板10とを連結するように固定することで、隙間G、Gから熱交換せずに流入する空気を遮断し、送風機、通気路あるいはその周辺に結露するのを防止できる機能も得られる。 Further, the first and second heat exchanger fixtures 11 and 12 are fixed by the gaps G 1 and G 2 so as to connect the metal end plates 71 a, 72 a, 73 a and the resin end plate 10. Thus, it is possible to obtain a function of blocking the air flowing in without exchanging heat from the gaps G 1 and G 2 and preventing the air from condensing on the blower, the air passage or the vicinity thereof.

また、吸込口6b、6cから室内機本体11内に吸い込まれた空気は、隙間G、Gを通過しないため、熱交換器を通過しない流速の速い空気と、室内熱交換器7を通過し、流速が遅い空気との混合がなくなり、異常音を低減できる。 Moreover, since the air sucked into the indoor unit main body 11 from the suction ports 6b and 6c does not pass through the gaps G 1 and G 2 , it passes through the indoor heat exchanger 7 and air having a high flow velocity that does not pass through the heat exchanger. In addition, mixing with air having a low flow velocity is eliminated, and abnormal noise can be reduced.

さらに、両熱交換器固定具11、12により2箇所を固定することにより、各金属製端板71a、72a、73aと樹脂製端板10との位置ずれや変形を最小限に抑えることができると共に、隙間G、Gを確実に塞ぐことができる。 Furthermore, by fixing the two places with the heat exchanger fixtures 11 and 12, it is possible to minimize the displacement and deformation of the metal end plates 71a, 72a and 73a and the resin end plate 10. At the same time, the gaps G 1 and G 2 can be reliably closed.

また、両熱交換器固定具11、12を多層構造にし、両基材11a、12aを硬質部材とするため、両熱交換器固定具11、12の単体強度を確保でき、横幅の長い室内熱交換器7でも、両熱交換器固定具11、12の両端を固定するだけで、中央の浮きや反りをなくし、固定用の取付部品(ねじやクリップなど)を必要最低限にすることができる。   Moreover, since both heat exchanger fixtures 11 and 12 are made into a multilayer structure and both base materials 11a and 12a are made into a hard member, the single-piece | unit intensity | strength of both heat exchanger fixtures 11 and 12 can be ensured, and indoor heat with a long width Even in the exchanger 7, by simply fixing both ends of the heat exchanger fixtures 11 and 12, it is possible to eliminate center lifting and warping and to minimize the mounting parts (screws, clips, etc.) for fixing. .

さらに、両軟質部材11b、12bを用いることで、両熱交換器固定具11、12と室内熱交換器7の密着性を高めることができ、隙間G、Gを確実に塞ぐことができる。 Furthermore, by using both the soft members 11b and 12b, the adhesion between the heat exchanger fixtures 11 and 12 and the indoor heat exchanger 7 can be improved, and the gaps G 1 and G 2 can be reliably closed. .

また、両軟質部材11b、12bが室内熱交換器7に接触しているため、両シール部材11、12と室内熱交換器7間で生じるキシミ音を防ぐことができる。   Moreover, since both the soft members 11 b and 12 b are in contact with the indoor heat exchanger 7, it is possible to prevent squeak noise generated between the both seal members 11 and 12 and the indoor heat exchanger 7.

本実施形態に係る空気調和機によれば、簡単な構造で分割熱交換器を所定形状に確実に保持でき、隣接する分割熱交換器間に形成される隙間を確実に塞ぐことができるとともにシール部材の固定が確実で、その固定に多くの取付部品を要さず、安価な空気調和機が実現する。   According to the air conditioner according to the present embodiment, the split heat exchanger can be reliably held in a predetermined shape with a simple structure, and the gap formed between the adjacent split heat exchangers can be reliably closed and sealed. The fixing of the members is reliable, and many fixing parts are not required for the fixing, and an inexpensive air conditioner is realized.
