りである。Next, the operation will be described. First, assuming that the air volume is set to "strong" by the operation means 3, this signal is sent to the control signal 7, and the control means 7 starts with the first timer means 5
Start timing. At the same time, since the first timer means 5 is operating to the switching means 4, the control signal of the air volume "strong" (strongest operation) is sent. The switching means 4 to which the control signal is sent rotates the motor 2 at a rotation speed corresponding to the air volume "strong". When the first timer means 5 finishes the time counting operation, an end signal is output to the control means 7, the control means 7 then starts the time counting of the second timer means 6, and the switching means 4 is "weak" (minimum operation). ) Control signal. The switching means 4 to which the control signal is sent causes the motor 2 to rotate the fan at the rotation speed corresponding to the air volume "weak". For example, the second timer means 6
If the clocking time of 2 is 2 seconds, after operating for 2 seconds at "weak" (minimum operation), an end signal is sent to the control means 7, and the control means 7 has reached the air volume set by the operation means 3. Recognizing whether or not it has not arrived yet (because it is a "strong" setting, it has not yet arrived), so that the second timer means 6 restarts the time measurement and at the same time the air volume "standard" switching means 4
Send to When it is "standard" for 2 seconds, that is, when the time counting operation of the second timer means 6 is completed, an end signal is sent to the control means 7 as in the case of "weak", and the control means 7 is operated by the operation means 3 described above.
Recognize whether or not the air volume set in is reached,
Since it has not reached, the second timer means 6 restarts the time measurement, and at the same time, the air volume "strong" is sent to the switching means 4.
When the second timer means 6 operates for 2 seconds with "strong" and finishes measuring the predetermined time, it sends an end signal to the control means 7 and recognizes whether the air volume is the one set by the operation means 3 or not. Therefore, the air volume "strong" is sent to the switching means 4 as a control signal. The switching means 4 to which the control signal is sent rotates the motor 2 at a rotation speed corresponding to the air volume "strong".
Even when set to "strong" in this way, since "strong" air volume is not obtained suddenly from the beginning but is obtained in stages, quiet operation can be performed. Even when the air volume is set to "standard", the same stepwise operation as described above is performed. These states are as can be understood from FIGS. 3A and 3B.
なお、最初の設定が「弱」の場合は第１タイマー手段
５の作用により、瞬間的な時間（0.1秒）だけ「強」の
動作をしたのち、「弱」に移行するものであるため、立
ち上がり時の騒音は非常に小さいものである。When the initial setting is "weak", the action of the first timer means 5 causes the action to be "strong" for a momentary time (0.1 seconds), and then shifts to "weak". The noise when standing up is very low.
ここで、風量を３段階の場合について説明してきた
が、段階が多いほど滑らかな運転を得ることができる。Here, the case where the air volume is in three stages has been described, but the more stages there are, the smoother the operation can be obtained.
