出される空気の流線にそって設けられている。When the vacuum cleaner is operated, the shaft 2 of the electric motor rotates and the first
(counterclockwise in the figure), and the fan 1 rotates at the same time. Due to this rotation, air flows in from the suction port 4, and the blade 5
is pushed and discharged to the outer periphery of the fan 1. The discharged air is rectified by the guide vanes 7 of the air guide 6,
It is led into the interior of an electric motor (not shown) through a slow passageway 8 provided at its terminal end. Near guide 60 guide vane 7tl
In order to rectify the air efficiently, it is installed along the streamline of the air being discharged.
この案内羽根７の位置は、空気負荷がほぼ一定で、風雪

気の流線が大きく変動し、案内羽根７と空気の流線がず
れると送風効率が低下し、騒音が大きくなるという欠点
があった。The position of the guide vane 7 can be set at the optimal position when the air load is almost constant and the wind and snow are almost constant, since the flow line 6 is also almost constant, but in the case of a load that sucks in dirt like a vacuum cleaner. The air volume changes greatly depending on the amount of dirt accumulated in the filter and the condition of the surface to be cleaned (for example, there is less wind and snow on carpets, and more on floors; Furthermore, the air flow rate increases), the flow line of the air fluctuates greatly, and if the guide vane 7 and the flow line of the air deviate from each other, the air blowing efficiency decreases and the noise increases.
発明の目的
本発明はこのような従来の欠点を解消したもので、使用
風量が変化しても、送風効率を維持し、騒音の発生を抑
止しようとするものでちる。OBJECTS OF THE INVENTION The present invention eliminates these conventional drawbacks, and aims to maintain air blowing efficiency and suppress noise generation even if the amount of air used changes.

すること？図ったものである。Structure of the Invention The blower of the present invention includes a suction fan rotating on the axis of an electric rock, and an air guide with guide vanes installed around the outer circumference of the fan.
By elastically supporting these guide vanes in the direction of the rotation plane of the suction fan and making the relative angle with the suction fan variable, the guide blades are always guided even if the amount of air discharged from the suction fan changes or the streamline direction changes. By aligning the blades with the streamlines of the air, it is possible to maintain good air blowing efficiency and suppress the generation of noise. It was planned.
実施例の説明 以下その実施例全添付図面とともに説明する。Description of examples The embodiment will be described below with reference to all the attached drawings.
第２図、第３図において、１１は吸込ファンで、その中
央前方に吸込口１２が、その外周に羽根１３が側板１４
．１５にはさ１れて設けられている。In FIGS. 2 and 3, reference numeral 11 denotes a suction fan, with a suction port 12 at the center front, and blades 13 on the outer periphery of the fan 11 on the side plate 14.
．． 15.
吸込ファン１１の外周及び底部にはエアガイド１６が、
吸込ファン１１の前方及びエアガイド１６の外周にはフ
ァンケーシング１７が設けられている。An air guide 16 is provided on the outer periphery and bottom of the suction fan 11.
A fan casing 17 is provided in front of the suction fan 11 and on the outer periphery of the air guide 16.
ファンケーシング１γにはその中央部に前記吸込ファン

成している。A suction port 18 corresponding to the suction port 12 of the suction fan 11 is opened in the center of the fan casing 1γ, and a skirt 19 on the outer periphery forms an air passage together with the air guide 16.

。The air kite 16 is provided with a plurality of guide cylinders @2o rotatably fixed at fixing points 21 near its inner periphery, and is made of an elastic material. Reference numeral 22 denotes an air passage formed by the guide vanes 20, which terminates at a communicating passage 23 opened below the air guide 16 at its outer circumferential end, and this communicating passage 23 is connected to the inside of the electric cylinder (not shown). in the process of.

慎により吸込ファン１１が回転（第３図の場合反時計方
向）し、空気は吸込口１８→吸込ロ１２→フアン１１の
内部→空気通路２２→連通路２３と流れ、空気通路２２
で案内羽根２Ｑにより整流される。In the above configuration, when the vacuum cleaner is operated now, the suction fan 11 rotates (counterclockwise in the case of Fig. 3) due to the electric shock, and the air flows from the suction port 18 → the suction hole 12 → the inside of the fan 11 → the air Flows from passage 22 to communication passage 23, air passage 22
The flow is then rectified by the guide vane 2Q.
案内羽根２０はその同端近くの固定点２１で固定され、
外端は自由で弾性があるため、床ノズルを床面から持ち

止まる（第３図破線）。The guide vane 20 is fixed at a fixed point 21 near its same end;
Since the outer end is free and elastic, when the floor nozzle is lifted from the floor surface, the suction air volume increases, and the airflow discharged from the fan 11 has a large outward velocity component. In particular, the rectifier preelectric @Sakura used in vacuum cleaners is Sihuan 1, which has a large air volume.
When the load of 1 increases, the rotation speed decreases significantly, so
The rotational velocity component of the air becomes smaller, and the airflow flows toward the outer circumferential direction. Therefore, the air hits the inside of the guide vane 20 more strongly, and the guide vane 20 rotates toward the outer circumference using the 21 fixed points near its inner end as fulcrums.
It stops when the elastic force of the guide vane 20 and the contact force of the air are balanced (broken line in Figure 3).

こめ案内羽根２０はその弾性力に、Ｊ：９内周方向へ回
転移動する（第３図実線）。Conversely, when the floor nozzle is attached to the surface to be cleaned and the actual cleaning is performed, the intake air volume is small and the airflow discharged from the fan 11 has a small outward velocity component, which reduces the load on the fan 11. , the rotation speed of the electric fan is x<zp, the component of the air flow to the fan 110 rotations becomes large, and the air flow becomes f
The flow is directed in the direction of rotation of the winding fan 110. This one
Due to the elastic force, the temple guide blade 20 rotates in the J:9 inner circumferential direction (solid line in FIG. 3).
したがって、空気の量によって案内羽根２００角度が変

る。Therefore, the angle of the guide vanes 200 changes depending on the amount of air and follows the streamline direction of the air, increasing the air rectification effect and maintaining high efficiency regardless of changes in air flow rate.
In addition, since the guide vanes align with the streamline direction of the air, there is less air sagging and collisions, and noise can be kept low.

が良いものである。Regarding the flow direction of the air, if it is a normal household vacuum cleaner, is it the floor nozzle? Approximately 165~2.0cm when lifted from the floor.
Of? //f+ air flows and the angle of the guide vane 20 that connects the air flow discharged from the fan 11 with the tangent to the fan is preferably 3° to 6° at its starting end, and the floor nozzle is attached to the surface to be cleaned. If you actually clean it, it will be about 1.0 to 1.4 m.
' / minute of air flows, the angle of the guide vane 20 is 00~3°
is good.
