Claims (1)
動される送風フアンと、前記直流電動機の回転を
制御する制御手段とを具備する扇風機において、
前記直流電動機は、回転子のマグネツトと相対し
て配置され前記制御手段に回転子位置信号を出力
する回転子位置検出手段を有し、送風フアンが下
向きに位置して転倒した際に前記マグネツトと回
転子位置検出手段との間が所定距離より長く離間
し、前記制御手段への回転子位置信号の入力を停
止し、送風フアンが上向きに位置して転倒した際
にはスイツチ手段により回転子位置信号の前記制
御手段への入力を停止させるようにしたことを特
徴とする扇風機。 An electric fan comprising a DC motor, a blower fan rotationally driven by the DC motor, and a control means for controlling rotation of the DC motor,
The DC motor has rotor position detection means that is disposed opposite to the magnet of the rotor and outputs a rotor position signal to the control means, and when the blower fan is positioned downward and falls over, the rotor position detection means is arranged opposite to the magnet of the rotor. If the distance between the rotor position detection means and the rotor position detection means is longer than a predetermined distance, the input of the rotor position signal to the control means is stopped, and when the blower fan is positioned upward and falls over, the rotor position is determined by the switch means. An electric fan, characterized in that input of a signal to the control means is stopped.
