〈産業上の利用分野〉
本発明は、複写機、冷暖房機器、事務機器等の内蔵用に
広く供せられているクロスフローファンである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention is a cross-flow fan that is widely used in copying machines, air-conditioning equipment, office equipment, and the like.
〈従来の技術〉
従来此種のファンにあっては、一定送風容量のもののみ
であるため、機器内部の加熱或は送風状態に於て、その
使用は大形のもの。<Prior art> Conventionally, this type of fan only has a fixed airflow capacity, so it is necessary to use large-sized fans when heating or blowing air inside the equipment.
又は小形ファンの使い分けによることが多いが実際は機
器内スペースの問題がＭ要のため、その使用に苦心し【
いるのが現状である。Or, it often depends on the use of small fans, but in reality, there is a problem with the space inside the device, so it is difficult to use them [
The current situation is that

As shown in Fig. 1, a large number of wing pieces (1) are attached to a circular plate (2) to form a cylindrical shape. A cross-flow fan of the required width is used as the base fan A, and as shown in Figure 4A, on one side of this base fan, the support shaft (3) is loosely inserted into the shaft bearing (4) of the auxiliary fan B, which has the same shape as the base fan. and the wing pieces of both fans A and B (
1) The ends are butted against each other and engaged as shown in FIG. 3, and when the base fan A is rotated in the direction of arrow a, the auxiliary fan B is pushed by the blades of A7 and rotates at the same time.

The auxiliary fan B is engaged with the base fan A by, for example, a clutch mechanism or the like so that they rotate together. However, in the case of FIG. 4, the motor rotation shaft is inserted into the boss (5) after engagement, which is an example of an embodiment for increasing the air blowing width or the air blowing amount of 7 mm, which is a base body of a predetermined width.

ある。<Effects of the Invention> As described above, the present invention mainly describes the engagement rotation of two fans, but is not limited to two fans, and is not limited to the rotation of two or more fans into a single fan. It is fitted onto a rotating support shaft and rotates all the fans at the same time or partially rotates the auxiliary fan to adjust the air volume. It is convenient and economical that the wind direction can be distributed by the guide plate, and can be done by one motor.
