本発明は、空調機などに使用される遠心送風装置に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a centrifugal blower used in an air conditioner or the like.
従来の技術
従来のこの種の送風装置は第3図に示すように、羽根車
1と渦巻きケーシング2aとモータ5とから構成されて

に連動されて回転する構造となっている。BACKGROUND OF THE INVENTION A conventional blower device of this type is composed of an impeller 1, a spiral casing 2a, and a motor 5, as shown in FIG. An intake port 4a is formed on one end surface of the spiral casing, and a centrifugal impeller is housed inside. This impeller is provided outside the winding casing and rotates in conjunction with a T motor.
この構成によれば、羽根車の回転により吸気口から吸入
されrこ空気は羽根車から周方向に吹出し、渦巻きケー
シングにより吐出口3cに集められ吐出される。According to this configuration, air is sucked in from the intake port by the rotation of the impeller, is blown out from the impeller in the circumferential direction, and is collected by the spiral casing at the discharge port 3c and discharged.
ま1こ、別の従来技術として、多方向への吹出しを可能
にし1こものがあり、第4図に示し1こように相反する
2方向に吐出口3d、30を形成しにケーシング2bや
第5図a、 bに示し1こような両吸込み用の羽根車
la、ケーシング2cによる構成も利用されている。There is another conventional technology that allows air to be blown out in multiple directions, as shown in FIG. A structure including a dual-suction impeller la and a casing 2c as shown in FIGS. 5a and 5b is also used.
発明が解決しようとする問題点
しかしながら上記の基本構成では、吐出口が1つである
ため使用範囲が制約されるという欠点を有し、多方向吹
出しの構成のうち、相反する2方向に吐出口を設け1こ
ケーシングの場合には、180゜反対方向の吹出しでは
舌部の位置が羽根車中心に対して対称になり両吐出口へ
均等に送風されるが、90°程度の角度で2万回に吐出
する場合や任意の複数の方向へ吐出する場合は舌部から
吐出口までのボリュート巻き角が各吐出口に対して一定
にならず、均等に多方向へ送風することが困難になる。Problems to be Solved by the Invention However, the above-mentioned basic configuration has the disadvantage that the scope of use is restricted because there is only one outlet. In the case of a single casing, the position of the tongue becomes symmetrical with respect to the center of the impeller when blowing in the opposite direction by 180 degrees, and the air is blown equally to both outlets, but at an angle of about 90 degrees, When discharging at once or in multiple arbitrary directions, the winding angle of the volute from the tongue to the discharge port is not constant for each discharge port, making it difficult to blow air evenly in multiple directions. .
ま1こ、両吸込みの構成では、吸気口を2カ所に設ける
必要があることや両吸込み用の羽根車が必要であるとい
う製作上の短所の他に、ベルマウス付近に生じる羽根効
率の悪い循環領域が羽根車の両端に生じることになり羽
根車全体の効率も低下するという欠点ヲ有していrこ。In addition to the manufacturing disadvantages of the double suction configuration, such as the need to provide intake ports in two locations and the need for impellers for both suctions, there is also the problem of poor impeller efficiency near the bell mouth. This has the disadvantage that circulation regions are formed at both ends of the impeller, reducing the efficiency of the entire impeller.
問題点を解決する1こめの手段
上記問題点を解決する1こめに、本発明の送風装置にお
いては、羽根車を収納する渦巻きケーシングは、巻き始
め位置と吐出方向の異なる複数の渦巻きを羽根車の回転
軸方向に積み重ねて形成され、この中にモータと連動し
γこ遠心式の羽根車を収納する構成をとっている。First Means to Solve the Problems First, in the blower device of the present invention, the spiral casing housing the impeller has a plurality of spirals with different winding start positions and discharge directions. The impellers are stacked in the direction of the rotational axis, and a gamma centrifugal impeller that operates in conjunction with the motor is housed inside the impeller.
作 用
本発明は上記のように、羽根車の回転軸方向に、巻き始
め位置をすらし1こ渦巻き全積み重ねfコ構造のケーシ
ングを採用しているγこめに、各層毎に巻き始め位置と
吐出方向が異なっており、渦巻きケーシングのどのit
流れるかによって吐出方向が異なるので、1つのケーシ
ングで多方向への吹出しを実現することが出来る。As described above, the present invention has a winding start position and a winding start position for each layer in the direction of the rotational axis of the impeller, in which the casing has a single spiral, fully stacked f-co structure. The discharge direction is different, which of the spiral casing
Since the discharge direction differs depending on the flow, it is possible to realize discharge in multiple directions with one casing.
実施例 以下本発明の実施例全添付図面にもとづいて説明する。Example Embodiments of the present invention will be described below with reference to all the accompanying drawings.
第1図において、1は羽根車、2は渦巻きケーシングで
ある。この渦巻きケーシングは2方向への吐出口3a、

体の形状はほぼ同じであるからその性能は同じと考えら
れ、羽根高さ方向の吐出速度分布のみを考慮してやれば
再吐出口から均等に吐出することは容易である。In FIG. 1, 1 is an impeller and 2 is a spiral casing. This spiral casing has discharge ports 3a in two directions,
3b, and the spirals are stacked in the upper and lower layers of the spiral casing with an offset of about 90 degrees. I was angry,
The air flowing in from the intake port 4 exits the impeller and is divided into the upper layer and the lower layer of the spiral casing and discharged in different directions. In this configuration, since the shapes of the stacked spirals themselves are almost the same, their performance is considered to be the same, and if only the discharge velocity distribution in the blade height direction is considered, it is easy to discharge evenly from the re-discharge port. It is.
ま1こ、片吸込みであるfこめ、羽根のベルマウス近傍
の循環領域は羽根車の片側だけ(こ生じ、羽根の両端に
循環領域の生じる両吸込み構成よりも高効率の送風機と
なる。However, since it is a single suction, the circulation area near the bell mouth of the blade is only on one side of the impeller (this results in a more efficient blower than a double suction configuration with circulation areas at both ends of the blade).
発明の効果
以上のようをこ本発明の送風装置によれば、任意の複数
方向への吹出しが可能であり、かつ、各吐出口から均等
に吐出することが容易であるという効果が得られる。Effects of the Invention As described above, according to the blowing device of the present invention, it is possible to blow air in any plurality of directions, and it is easy to blow air uniformly from each outlet.
ま1こ、片吸込みである1こめ、吸気口が一面だけで良
く、羽根車も両吸込み用の特殊なものでなくて良いとい
う利点の他に、ベルマウス近傍の循環領域が羽根車の一
端のみに生じ、循環領域が両端に生じる両吸込み構成に
比べると効率が良くなるという効果が得られる。In addition to the advantage that the single suction system only requires one intake port on one side and the impeller does not need to be a special type for both suctions, the circulation area near the bell mouth is located at one end of the impeller. The effect is that the efficiency is improved compared to a dual suction configuration in which circulation areas occur at both ends.
