【発明の詳細な説明】 本発明は、空気調和機、特に天井吊型として好
適な空気調和機に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner, particularly an air conditioner suitable as a ceiling-suspended type.

最近の空気調和機の動向としては、省エネルギ
化からの機内抵抗の低減、省スペース化からの薄
形化、及び快適性の観点からの気流分布の改善が
大きな課題になつている。 Recent trends in air conditioners include reducing internal resistance to save energy, making them thinner to save space, and improving airflow distribution from the standpoint of comfort.

出すようにされている。 For example, in a conventional ceiling-suspended air conditioner, the first
As shown in the figure, a large number of Sirotskov fans 3' are arranged in parallel in a casing 1' equipped with an air inlet 4' on the back and an air outlet 5' on the front, and air heat is provided facing the air outlet 5'. The exchanger 2' is installed on the ceiling C near the wall T of the room, and the air W sucked in from the back is blown out from the front.

ところが、この場合、以下に述べるような問題
点があつた。 However, in this case, there were problems as described below.

(1) 空気熱交換器２′が正面のみに配設されてい

厚さｈが大きくなる。例えば、３程度の空気
調和機でｈ≒18cmとなる。(1) The air heat exchanger 2' is only installed at the front, and the height (number of stages) needs to be increased due to the required heat exchanger capacity. Since the spiral casing 3a' is surrounded by the spiral casing 3b', the thickness h of the fuselage body becomes large. For example, h≒18cm for a 3rd grade air conditioner.

(2) 限られた横寸法のケーシング１′内に多数の
シロツコフアン３′を配設しなければならない
ので、ケーシング１′内において複雑な曲り流
路が形成されることとなり、機内抵抗が大きく
なる。(2) Since a large number of Sirotskov fans 3' must be placed inside the casing 1' with a limited horizontal dimension, a complicated curved flow path is formed inside the casing 1', which increases the internal resistance of the machine. .

(3) 部屋の隅に設置されるので、例えば細長い部
屋の場合は、遠方まで空気を送る必要が生じ、
空気吹出口５での流速を５〜６ｍ／ｓと大きく
しなければならず、そのための動力消費が大き
かつた。(3) Since it is installed in the corner of the room, for example, if the room is long and narrow, it may be necessary to send air far away.
The flow velocity at the air outlet 5 had to be increased to 5 to 6 m/s, which required a large amount of power consumption.

る。(4) In a heating/cooling model, during heating operation, warm, buoyant air is blown out from the air outlet 5' in the front, flows along the ceiling, and the area near the ceiling of the room is warm and the floor This means that the area nearby is cold, which is a problem from an energy conservation perspective.

That is, the front curved surface 13a from the front edge to the middle part has a radius with respect to the drive shaft 6a of the motor 6 that gradually decreases along the flow of intake air, while the rear curved surface 13b from the middle part to the rear edge has the shape as described above. It has a shape in which the radius gradually increases along the flow of the discharged air. A main plate part 14 to which the drive shaft 6a of the motor 6 is coupled is provided approximately at the center of the inner surface of the hub 10, and can be integrally molded with synthetic resin.

である。 Next, to explain the operation of the air conditioner of the first embodiment, the air flow W blown in from the air suction port 4 opened on all sides of the casing 1, when passing through the square annular air heat exchanger 2, After heat exchange, the air flows centripetally through the suction air passage 8 and reaches the inlet of the centripetal fan 3, and then centripetal acceleration diagonally inward and diagonal acceleration diagonally outward are performed by the centripetal fan 3. In response to this, the air is slowly blown out from the air outlet 5 into the room over a wide range, thereby cooling or heating the room.

である。 Therefore, in the air conditioner of this embodiment, since the air heat exchanger 2 is disposed facing the air suction port 4 on the entire circumference of the side surface of the casing 1, the number of stages of the heat exchanger can be increased. Since sufficient capacity is obtained and the centripetal fan 3 is configured in a flat shape with a large outer diameter, the thickness h of the fuselage body can be reduced.

る。 In addition, the centripetal fan 3 used in this embodiment does not require the installation of stationary blades like a normal centripetal fan, and has excellent static pressure rise, allowing the desired air blowing capacity to be achieved at a low rotation speed. It is also possible to reduce noise.

続いて本発明の空気調和機の効果を以下に列記

Since a plurality of blades 11, 11, etc. are planted on the outer circumferential surface of the hub 10, which has an hourglass-shaped outer circumferential curve, there is no need to install stationary blades as in the case of using a normal centripetal fan, and smooth flow can be achieved. As a result of forming a path and increasing the effect of increasing static pressure, a desired air blowing capacity can be obtained at a low rotation speed, and noise can be reduced.

The air blows downward, and the distribution of warm air can be evened out during heating operation of dual-use air conditioners.

尚、上記実施例では、天井吊型について説明し
たが、本発明の空気調和機は、垂直方向に設置す
