Claims (1)
- 送風部に直流モータを搭載し、前記直流モータをPWM制御する制御部と、前記直流モータの運転開始を知らせる報知音を発生する報知部と、前記報知部に報知信号を出力する報知音制御手段を備えた扇風機において、
前記直流モータは起動から所定回転数に達するまでの(t1)時間矩形波駆動された後、正弦波駆動に切替えられ、
前記報知音制御手段は前記直流モータの起動から(t2)時間後に報知信号を出力開始して(t2')時間経過後に出力終了し、前記(t2)時間は前記(t1)時間より短く、
前記(t2')時間は、前記直流モータが矩形波駆動から正弦波駆動に移行する過程で発生する音が継続する(t1')時間より長いことを特徴とする扇風機。
