の改良に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner that constitutes, for example, an indoor unit, and more particularly to improvement of a heat exchanger structure.
【０００２】[0002]
【従来の技術】一般的に用いられる空気調和機は、被空

び電気配線で接続してなる。2. Description of the Related Art An air conditioner generally used comprises an indoor unit arranged in a room to be air-conditioned and an outdoor unit arranged outdoors, and these units are connected to each other by a refrigerant pipe and electric wiring. .
【０００３】ユーザ側からは、これらユニットに対する
小形化と、据付スペース低減の要望が大であり、各メー
カにおいては、このような条件を満足しつつ、熱交換能
力の増大を図らなければならない。From the user side, there is a great demand for miniaturization of these units and reduction of the installation space, and each maker must increase the heat exchange capacity while satisfying such conditions.
【０００４】その解決策の一つとして、近時、特に室内
ユニットでは、ここに配備される熱交換器を”くの字
状”に折り曲げ形成して、熱交換面積を確保しつつ、熱
交換器自体の高さ寸法を抑制し、ユニット本体の高さ寸
法の低減化を得ている。As one of the solutions, in recent years, especially in indoor units, the heat exchangers provided here are bent and formed in a "dogleg" shape to secure a heat exchange area and heat exchange. The height of the container itself is suppressed and the height of the unit body is reduced.
【０００５】ところで、室内ユニットには、被空調室空
気をユニット本体内に吸込み、熱交換器を導通させて熱
交換作用を行なわせ、熱交換した後の空気を再び被空調
室へ吹出す送風ファンが配置されていて、その性能上、
横流ファンが採用される。By the way, in the indoor unit, the air to be conditioned room is sucked into the main body of the unit, the heat exchanger is conducted to perform the heat exchange action, and the air after the heat exchange is blown again to the room to be conditioned. There is a fan, and due to its performance,
A transverse fan is adopted.

設定によっては、熱交換器の上，下端部の、少なくとも
いずれか一方は横流ファンから遠く離間して、熱交換空
気が導かれ難く、部分的に熱交換効率に差が生じてしま
う。This cross-flow fan is arranged on the rear side of the bent portion of the doglegged heat exchanger. Depending on the position setting of this bent portion, at least one of the upper and lower ends of the heat exchanger is arranged. The heat exchange air is difficult to be guided away from the cross flow fan, and the heat exchange efficiency partially varies.

【発明が解決しようとする課題】そこで、くの字状熱交

に対する通風量を増大させ、冷房能力と暖房能力の向上
を図れる。Therefore, for example, Japanese Utility Model Laid-Open No. 4-57073, which improves the dogleg-shaped heat exchanger, is disclosed. With such a heat exchanger bent in multiple stages, the height dimension can be reduced as compared with a simple doglegged heat exchanger, and moreover, the heat exchange area and the ventilation amount to the heat exchanger can be increased. , Cooling capacity and heating capacity can be improved.
【０００８】図１０に、この種の熱交換器一部を示す。
同図（Ａ）はプレス加工によって成形されたフィンＦを
示す。ここには幅方向と直交する方向に２列で、列方向
に所定ピッチのパイプ取付け用孔ａが設けられる。FIG. 10 shows a part of this type of heat exchanger.
FIG. 3A shows the fin F formed by press working. Here, two rows of pipe mounting holes a are provided in a direction orthogonal to the width direction, and the pipe mounting holes a having a predetermined pitch are provided in the row direction.
【０００９】互いの列の取付け用孔ａは、いわゆる千鳥
状に配置される。そして、各列のパイプ取付け用孔ａの
２つおきの中間部には、ジグザグ状に切り欠れた切欠き
部Ｋが設けられる。The mounting holes a in each row are arranged in a so-called zigzag pattern. A notch K is cut out in a zigzag shape at the middle of every two pipe mounting holes a in each row.
【００１０】同図（Ｂ）は、上記切欠き部Ｋの上下端縁
を接触して折り曲げ部Ｋａを形成した状態を示す。パイ
プ取付け用孔ａには熱交換パイプＰが貫通して設けられ
ていて、多段に折り曲げた熱交換器が成形されることに
なる。FIG. 1B shows a state in which the upper and lower edges of the cutout portion K are in contact with each other to form the bent portion Ka. A heat exchange pipe P penetrates through the pipe mounting hole a, and a heat exchanger bent in multiple stages is formed.
【００１１】問題１．上記切欠き部Ｋは、フィンＦに複
数か所設けるところから、多数枚のフィンから多量の端
材が出ることが避けられない。これら端材は別途使用す
ることができず、無駄である。そして、折り曲げ部Ｋａ
を得るために切欠き部Ｋの数と同数の曲げ工程が必要で
作業手間がかかり、コストに悪影響を与えている。Problem 1. Since the notch K is provided at a plurality of places on the fin F, it is inevitable that a large amount of scrap material comes out from a large number of fins. These end materials cannot be used separately and are wasteful. And the bent portion Ka
In order to obtain the above, the same number of bending steps as the number of the cutouts K is required, which requires a labor and a negative effect on the cost.
【００１２】問題２．各列における切欠き部Ｋ相互間の
熱交換パイプＰ相互の距離ｓ1 は、折り曲げ後も変化し
ないが、切欠き部Ｋを跨いだ位置では、折り曲げたこと
によって距離ｓ3 あるいはｓ4 に変わる。Problem 2. The distance s1 between the heat exchange pipes P between the notches K in each row does not change even after bending, but at the position across the notches K, it changes to the distance s3 or s4 due to the bending.
【００１３】すなわち、折り曲げ外側列と、内側列とで
若干の相違が生じるが、いずれにしても折り曲げ後は狭
くなる。千鳥状に配置される各列相互の距離ｓ2 も同様
で、切欠き部Ｋ相互間では変化しないが、跨ぐ位置の距
離ｓ5 は狭くなる。That is, there is a slight difference between the folded outer row and the inner row, but in any case, it becomes narrower after folding. The distances s2 between the rows arranged in a staggered pattern are the same, and the distances s5 at the straddling positions are narrow, although they do not change between the notches K.
【００１４】このように同一熱交換器内で各列相互の距
離がｓ2 およびｓ5 の２種類が混在することになり、こ
れらの部分での通風抵抗にアンバランスが生じ、熱交換
効率が低下したり、送風騒音が大きくなってしまう。As described above, in the same heat exchanger, the two types of distances s2 and s5 are intermingled in each row, and the ventilation resistance in these portions becomes unbalanced, and the heat exchange efficiency decreases. Or the blast noise becomes loud.
【００１５】さらに、熱交換パイプＰは予めＵ字状に形
成されていて、熱交換器の組立て時に２つの取付け用孔
ａ，ａに同時に挿通される。このＵ字状部は一側端のフ
ィンから突出し、両端開口部は他側端のフィンから突出
する。Further, the heat exchange pipe P is formed in a U shape in advance and is inserted into the two mounting holes a, a at the same time when the heat exchanger is assembled. The U-shaped portion projects from the fin at one end, and the openings at both ends project from the fin at the other end.
【００１６】隣接する熱交換パイプの開口端相互にＵベ
ンド等の配管部品を接続して必要な流路を得る。ただ
し、上記した熱交換器では、接続端部距離が多種類ある
ので、それに応じた種類の配管部品を用意しなければな
らず、部品費がかさむ。Piping parts such as U-bends are connected to the open ends of the adjacent heat exchange pipes to obtain a necessary flow path. However, in the heat exchanger described above, since there are many types of connection end distances, it is necessary to prepare piping components of the types corresponding thereto, which increases the cost of components.
【００１７】問題３．同図では示していないが、熱交換
器の熱交換効率向上を図るため、熱交換パイプＰ各列に
沿って切り起しスリットが設けられる。ただしプレス加
工上、切欠き部Ｋの端縁に沿う部分には成形できない。Problem 3. Although not shown in the figure, cut and raised slits are provided along each row of the heat exchange pipes P in order to improve the heat exchange efficiency of the heat exchanger. However, due to press working, it cannot be formed in a portion along the edge of the notch K.
【００１８】そのため、同図（Ｂ）でハッチング線で示
す、切り起しスリットが設けられていない部分Ｄにおけ
る熱交換空気の流動抵抗が減少し、風速が大になる。結
果として、この熱交換器では部分的に熱交換空気の流通
速度が不均一になり、熱交換効率低下の一因となる。Therefore, the flow resistance of the heat exchange air in the portion D where the cut-and-raised slit is not provided, which is shown by the hatching line in FIG. 1B, is reduced, and the wind speed is increased. As a result, in this heat exchanger, the flow rate of the heat exchange air is partially non-uniform, which causes a decrease in heat exchange efficiency.
【００１９】フィンＦに切り起しスリットをプレス加工
するにあたって、同図（Ａ）に二点鎖線で示す範囲が、
１ストロークプレスとなる。加工後、フィンＦは長手方
向に１ピッチ分だけ送られ、同じ範囲で加工が繰り返さ
れる。When the fin F is cut and raised and the slit is pressed, the range indicated by the chain double-dashed line in FIG.
It is a one-stroke press. After processing, the fins F are fed by one pitch in the longitudinal direction, and the processing is repeated within the same range.
【００２０】切り起しスリット自体は、フィンＦの長手
方向に沿って均一の密度で備えられる。これに対して熱
交換器を流通する熱交換空気の風速は、送風ファンに接
近した部位で大、離間した部位で漸次小となる。The cut-and-raised slits themselves are provided with a uniform density along the longitudinal direction of the fin F. On the other hand, the wind speed of the heat exchange air flowing through the heat exchanger becomes high at a portion close to the blower fan and gradually becomes small at a portion separated from it.
【００２１】このように切り起しスリットは流通抵抗と
なるにも拘らず、熱交換器を流通する熱交換空気の風速
分布と全く無関係に均一に設けられているので、風速不
均等による熱負荷不均等が生じ、熱交換器としての性能
を最大限利用できない。Although the cut-and-raised slits thus have a flow resistance, the slits are evenly provided irrespective of the wind velocity distribution of the heat exchange air flowing through the heat exchanger. Inhomogeneity occurs, and the maximum performance of the heat exchanger cannot be utilized.
【００２２】問題４．各列の熱交換パイプＰの取付け用

み合わせが均一に配置されていることには変わりがな
い。Problem 4. The mounting holes a of the heat exchange pipes P of each row are provided at a uniform pitch along the longitudinal direction of the fins, and the pitch of each row is different in the bent state, but the heat exchange pipes P as a whole are different from each other. There is no change in that the combination of pipe pitches is evenly arranged.
【００２３】これに対して熱交換器を流通する熱交換空
気の風速は、送風ファンに接近した部位で大、離間した
部位で漸次小となる。熱交換パイプは熱交換空気の風速
条件とは全く無関係に設けられ、風速不均等による熱負
荷不均等が生じて、熱交換器としての性能を最大限利用
できない。On the other hand, the wind speed of the heat exchange air flowing through the heat exchanger becomes large at a portion close to the blower fan and gradually becomes small at a portion separated from it. The heat exchange pipe is provided irrespective of the wind speed condition of the heat exchange air, and the heat load becomes uneven due to the uneven wind speed, so that the performance of the heat exchanger cannot be utilized to the maximum extent.
【００２４】問題５．フィンＦは、長手方向に沿って均
一の幅寸法に形成されている。これを多段に折り曲げ、
送風ファンの周面一部を囲むように配置しても、熱交換
空気の風速は、送風ファンに接近した部位で大、離間し
た部位で漸次小となる。Problem 5. The fins F are formed with a uniform width along the longitudinal direction. Bend this in multiple stages,
Even if the heat exchange air is arranged so as to surround a part of the peripheral surface of the blower fan, the wind speed of the heat exchange air becomes large at a portion close to the blower fan and gradually becomes small at a separated portion.
【００２５】したがって、フィンＦの幅方向に沿って流
通する熱交換空気の風速分布と、フィンの幅寸法とは全
く無関係に設定され、風速不均等による熱負荷不均等が
生じ、熱交換器としての性能を最大限利用できない。Therefore, the wind speed distribution of the heat exchange air flowing along the width direction of the fins F and the width dimension of the fins are set independently of each other, and the heat load becomes non-uniform due to the non-uniform wind speeds. You can't take full advantage of the performance of

反対側の側縁から１つの切込み部が設けられていて、こ
こを境に折り曲げられる。したがって、熱交換器は、前
側熱交換器と後側熱交換器との連設体となり、側面視で
逆Ｖ字状をなす。Problem 6. The fin is provided with one notch from the side edge opposite to the notch, and the fin is bent at this notch. Therefore, the heat exchanger is a continuous body of the front heat exchanger and the rear heat exchanger, and has an inverted V shape in a side view.
【００２７】これら前側熱交換器と後側熱交換器の連結
部分の熱交換パイプ相互に、Ｕベンド等の配管部品が接
続されて連通されるが、この部分の熱交換パイプ距離は
各列内の熱交換パイプ管の距離と異なるため、この部分
のためにさらに別種の配管部品を用意する必要がある。A pipe part such as a U-bend is connected to and communicates with the heat exchange pipes at the connecting portion of the front heat exchanger and the rear heat exchanger. The heat exchange pipe distance at this portion is within each row. Since the distance of the heat exchange pipe is different, it is necessary to prepare another type of piping component for this portion.
