る。DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. The air conditioner is an outdoor unit that is installed outdoors,
An indoor unit, a heat source unit for supplying hot water, and the like are provided in the room, and the outdoor unit and the indoor unit are connected by a refrigerant pipe.

装置１３等により構成されている。FIG. 1 is a schematic view of such an air conditioner. An outdoor unit 10 includes a compressor 11 for compressing a refrigerant, an outdoor heat exchanger 12 for exchanging heat between the refrigerant and the outside air, and a decompression device 13 for decompressing or restricting the refrigerant. It consists of.

ボイラ等により構成されている。The indoor unit 20 is mounted above the wall surface of the conditioned room, and as shown in FIG. 2, a cooling heat exchanger 21, which is an indoor heat exchanger for exchanging heat between the refrigerant and the air in the conditioned room. A heating heat exchanger 22 for exchanging heat between hot water and the air in the conditioned room, a cross flow fan 23 for circulating the air in the conditioned room through the cooling heat exchanger 21 and the heating heat exchanger 22, and the like. Have been. Further, the heat source device 30
It is composed of a boiler and the like.

冷却用熱交換器２１や加熱用熱交換器２２を経ることに
より冷却又は加熱された後、風路４６を経て吐出口４２
から再度室内に吹出される。Then, the air in the conditioned room is taken into the indoor unit 20 from the intake port 41 by the cross flow fan 23,
After being cooled or heated by passing through the cooling heat exchanger 21 or the heating heat exchanger 22, the discharge port 42 is passed through the air passage 46.
From the room again.

ビライザー５１とに挟まれて構成され、リアケーシング
５０はクロスフローファン２３の径にあわせた角度で拡
がる曲面で構成されクロスフローファンの送風効率を高
めている。The air passage 46 is sandwiched between a rear casing 50 and a stabilizer 51. The rear casing 50 is formed of a curved surface that expands at an angle corresponding to the diameter of the cross flow fan 23 to increase the blowing efficiency of the cross flow fan. ing.
【００１４】吐出口４２の下板Ｂは風路４６の上下の幅
を狭くするように張出した凸状部４３を介してリアケー
シング５０につながっている。なおこの凸状部４３には
左右風向設定器４４が設けられている。The lower plate B of the discharge port 42 is connected to the rear casing 50 via a protruding portion 43 that protrudes so as to reduce the vertical width of the air passage 46. The convex portion 43 is provided with a left and right wind direction setting device 44.
【００１５】このように凸状部４３を所定の曲率にする
のは以下の理由からである。即ち、凸状部４３を平板に
した場合（従来の構造）、上下方向にも吹出が可能なよ
うにするためには、吐出口４２の室内端部は急激に広が
った構成となる。The reason why the convex portion 43 has a predetermined curvature is as follows. That is, when the convex portion 43 is a flat plate (conventional structure), the indoor end portion of the discharge port 42 has a configuration in which the indoor end portion is rapidly widened in order to be able to blow up and down.
【００１６】このためクロスフローファン２３により送
出される冷却された空気は、吐出口４２から吐出される
際に、この急激に広がった部分で膨張する。Therefore, when the cooled air sent out by the cross flow fan 23 is discharged from the discharge port 42, it expands in this rapidly expanded portion.
【００１７】かかる膨張により、吐出された空気の吐出

り、吐出口４２室内側端部が冷えて、冷却用熱交換器２
１により冷却されて過飽和状態となっている空気が結露
する。Due to the expansion, the discharged air is swirled at the inner end of the discharge port 42 indoors (in this part, the wind speed is reduced), and the temperature of the discharged air is lowered, so that the discharged air 42 The end cools down and the cooling heat exchanger 2
The supercooled air cooled by 1 forms dew.

４６を絞るように下板４３を曲面板に形成し、それ以降
室内側に向って徐々に吐出口４２が広がるようにするこ
とにより、吐出口４２室内側端部での膨張量を抑制して
結露の発生を防止している。Therefore, the lower plate 43 is formed into a curved plate so as to narrow the air passage 46 on the cross flow fan 23 side, and thereafter the discharge port 42 is gradually widened toward the indoor side, so that the discharge port 42 The amount of expansion at the indoor side end is suppressed to prevent dew condensation.

圧装置１３で減圧又は絞られる。When the cooling operation is performed in such a configuration,
The high-temperature and high-pressure refrigerant compressed by the compressor 11 is supplied to the outdoor heat exchanger 12, exchanges heat with the outside air, condenses, and is decompressed or throttled by the decompression device 13.

に戻る。冷却用熱交換器２１で蒸発する際の蒸発熱は、

却されて冷房が行われる。Thereafter, the refrigerant is supplied to the cooling heat exchanger 21 and exchanges heat with the air in the conditioned room to evaporate.
Return to The heat of evaporation when evaporating in the cooling heat exchanger 21 is:
Since air is taken from the conditioned room, the air in the conditioned room is cooled and cooled.

張することが無くなり吐出口４２の室内側端部での結露
の発生を抑制することができる。従って、長時間冷房運
転しても、結露による水が室内に滴るような事態は発生
しなくなる。At this time, since the convex portion 43 of the discharge port 42 is formed with a predetermined curved surface, the air in the conditioned room does not rapidly expand, and dew condensation occurs at the indoor end of the discharge port 42. Can be suppressed. Therefore, even when the cooling operation is performed for a long time, a situation in which water due to condensation is dripped into the room does not occur.
【００２２】一方、暖房運転時には、圧縮機１１を停止
して、熱源機３０から加熱用熱交換器２２に温水を供給
する。これにより被調和室の空気は温水と熱交換して温
風となって室内に吹出されて暖房が行われる。On the other hand, during the heating operation, the compressor 11 is stopped, and hot water is supplied from the heat source unit 30 to the heating heat exchanger 22. As a result, the air in the conditioned room exchanges heat with the hot water to become warm air and is blown into the room to perform heating.

室温の空気を室内に吹出すことにより除湿が行われる。When the dehumidifying operation is performed, the cooling operation and the heating operation are simultaneously performed, and the air in the conditioned room, which has been cooled by passing through the cooling heat exchanger 21 and has decreased in humidity, is cooled. The air is heated at 22 and the humidity is low, and the air at substantially room temperature is blown into the room to perform dehumidification.

り、この部分が結露しないようになる。As described above, according to the present invention, the lower plate of the discharge port on the cross flow fan side is formed in a convex curved shape so that the air path can be narrowed. The air cooled in the portion does not suddenly expand, and this portion does not condense.
