日本一些厂家应用模糊理论生产出新一代的电风扇。这种电风扇通过传感器探测室内温度、湿度,并以此为依据自动控制送风速,使其达到最佳效果。东芝的电风扇有7档风速,定时器将1～5h以内的时间分为286个档次,根据室湿自动调整送风量。三洋电机公司推出的新机种可以探知由遥控器发出的红外线信号,自动向遥控者的方向摇头送风。
Some Japanese manufacturers use fuzzy theory to produce a new generation of electric fans. This type of electric fan detects the indoor temperature and humidity through sensors, and based on this, automatically controls the speed of the air supply to achieve the best results. Toshiba’s fans have seven wind speeds. The timer divides the time within 1 to 5 hours into 286 grades, and automatically adjusts the air volume according to the room humidity. The new model introduced by Sanyo Electric Co., Ltd. can detect the infrared signal emitted by the remote controller and automatically shake the air toward the remote control.
