Claims (4)
該ファンモータの回転数が設定回転数になるようにパルス幅変調された制御信号のデューティ比を変える制御手段と、
前記制御信号を直流電圧に平滑する平滑回路と、
該平滑回路からの直流電圧に基づいて前記ファンモータを回転させる駆動手段とを備え、
前記制御手段は、ファンモータ起動時に、設定回転数で安定して回転しているときのデューティ比より所定値だけ大きいデューティ比の制御信号を前記駆動手段に出力することを特徴とする冷蔵庫。 A fan motor,
Control means for changing the duty ratio of the control signal pulse-width-modulated so that the rotational speed of the fan motor becomes the set rotational speed;
A smoothing circuit for smoothing the control signal into a DC voltage;
Driving means for rotating the fan motor based on a DC voltage from the smoothing circuit,
The refrigerator is characterized in that, when the fan motor is started, a control signal having a duty ratio larger by a predetermined value than a duty ratio when the fan motor is stably rotated at a set rotational speed is output to the driving means.
