圖2為本發明實施例提供的電風扇轉速控制方法的流程圖。FIG. 2 is a flowchart of a method for controlling an electric motor speed according to an embodiment of the present invention.
請參閱圖1，一種電風扇轉速控制系統10應用於一電風扇中，用於根據電風扇所處的環境溫度自動調節電風扇的轉速。該電風扇轉速控制系統10包括風扇葉片12、發動機14、儲存單元16、開關單元18、溫度感應單元20及控制單元22。Referring to FIG. 1, an electric fan speed control system 10 is applied to an electric fan for automatically adjusting the rotational speed of the electric fan according to the ambient temperature of the electric fan. The electric fan speed control system 10 includes a fan blade 12, an engine 14, a storage unit 16, a switch unit 18, a temperature sensing unit 20, and a control unit 22.
儲存單元16用於儲存一溫度轉速關係表。溫度轉速關係表用於表明環境的溫度及轉速之間的關係。溫度轉速表中的溫度範圍為28℃-36℃，轉速的範圍為500-1500轉/分鐘，且高溫度對應高轉速。The storage unit 16 is configured to store a temperature and speed relationship table. The temperature-speed relationship table is used to indicate the relationship between ambient temperature and speed. The temperature range in the temperature tachometer is 28 ° C - 36 ° C, the speed range is 500-1500 rev / min, and the high temperature corresponds to high speed.
開關單元18用於控制電風扇的開啟或關閉。溫度感應單元20用於在電風扇處於開啟狀態時感測電風扇所處的環境的溫度。該溫度感應單元20可為一包括熱敏電阻的電路。熱敏電阻的阻值會隨著溫度的升高而升高，在該電路在熱敏電阻的阻值變化時，輸出的電壓也發生變化，從而使該電路在不同溫度時輸出不同的電壓。該溫度感應單元20根據輸出的不同的電壓得出對應的環境的溫度。在本實施方式中，溫度感應單元20按照一預設時間，如兩小時，間隔週期性地感測電風扇所處的環境的溫度。在另一實施方式中，溫度感應單元20即時感測電風扇所處的環境的溫度。The switch unit 18 is used to control the opening or closing of the electric fan. The temperature sensing unit 20 is configured to sense the temperature of the environment in which the electric fan is located when the electric fan is in an on state. The temperature sensing unit 20 can be a circuit including a thermistor. The resistance of the thermistor will increase with the increase of temperature. When the resistance of the thermistor changes, the output voltage also changes, so that the circuit outputs different voltages at different temperatures. The temperature sensing unit 20 derives the temperature of the corresponding environment based on the different voltages output. In the present embodiment, the temperature sensing unit 20 periodically senses the temperature of the environment in which the electric fan is located according to a preset time, such as two hours. In another embodiment, the temperature sensing unit 20 senses the temperature of the environment in which the electric fan is located.
控制單元22用於根據感測到的環境的溫度及溫度轉速關係表控制發動機14按照與所感測到的環境的溫度對應的轉速進行轉動。發動機14用於驅動風扇葉片12轉動。The control unit 22 is configured to control the engine 14 to rotate according to the temperature corresponding to the temperature of the sensed environment according to the sensed temperature and temperature speed relationship table of the environment. The engine 14 is used to drive the fan blades 12 to rotate.
在本實施方式中，該溫度轉速表中還包括一預設臨界溫度，如25℃，控制單元22還用於在環境的溫度低於該預設臨界溫度時，控制開關關閉電風扇。如此，當溫度感測單元在電風扇以一轉速轉動轉動所述預設時間後再次感測到的環境的溫度小於25℃時，控制單元22將控制開關關閉風扇。因為環境小於25℃時，將不再需要吹風扇，可以防止一直將風扇開啟導致吹風扇的用戶感冒。In this embodiment, the temperature tachometer further includes a preset critical temperature, such as 25 ° C. The control unit 22 is further configured to control the switch to turn off the electric fan when the ambient temperature is lower than the preset critical temperature. Thus, when the temperature sensing unit detects that the temperature of the environment is less than 25 ° C after the electric motor rotates at a rotating speed for a predetermined time, the control unit 22 turns off the fan by the control switch. Since the environment is less than 25 ° C, the fan will no longer be needed, which prevents the fan from being turned on and causes the user of the fan to catch a cold.
該電風扇轉速控制系統10還包括顯示單元24。該顯示單元24用於顯示感測到的環境的溫度。如此，使用者可通過顯示單元24得知環境的溫度。The electric fan speed control system 10 also includes a display unit 24. The display unit 24 is for displaying the temperature of the sensed environment. In this way, the user can know the temperature of the environment through the display unit 24.
請參閱圖2，為一電風扇轉速控制方法的流程圖，該電風扇轉速控制方法應用於一電風扇中控制電風扇的轉速，該電風扇轉速控制方法包括的步驟如下所述。Please refer to FIG. 2 , which is a flowchart of a method for controlling the speed of an electric fan.

控制單元22根據感測到的環境的溫度及一表明環境的溫度及轉速之間關係的溫度轉速關係表控制電風扇的發動機14按照與所感測到的環境的溫度對應的轉速進行轉動（步驟S104）。其中，溫度轉速表中的溫度範圍為28℃-36℃，轉速的範圍為500-1500轉/分鐘，且高溫度對應高轉速。The control unit 22 controls the engine 14 of the electric fan to rotate according to the rotational speed corresponding to the temperature of the sensed environment according to the sensed temperature of the environment and a temperature and speed relationship table indicating the relationship between the temperature and the rotational speed of the environment (step S104). ). Among them, the temperature range in the temperature tachometer is 28 ° C -36 ° C, the speed range is 500-1500 rev / min, and the high temperature corresponds to the high speed.
發動機14驅動風扇葉片12轉動（步驟S106）。The engine 14 drives the fan blades 12 to rotate (step S106).
在一實施方式中，還包括步驟S108及步驟S110。In an embodiment, step S108 and step S110 are further included.
顯示單元24顯示感測到的環境的溫度（步驟S108）。The display unit 24 displays the temperature of the sensed environment (step S108).
控制單元22在環境的溫度低於一預設臨界溫度時，關閉電風扇。該預設臨界溫度為25℃（步驟S110）。The control unit 22 turns off the electric fan when the temperature of the environment is below a predetermined threshold temperature. The preset critical temperature is 25 ° C (step S110).
上述電風扇轉速控制系統10及控制方法根據電風扇所處的環境的溫度自動調節電風扇的轉速，無需用於自己動手進行調節，更加智慧。The electric fan speed control system 10 and the control method automatically adjust the rotation speed of the electric fan according to the temperature of the environment in which the electric fan is located, and it is not necessary to be used for self-adjustment and is more intelligent.
