[0010] 其工作原理如下: [0010] It works as follows:

[0011] 接通电源后,多谐振荡器振荡工作,从时基集成电路IC的3脚输出占空比可调的方波脉冲信号,使晶闸管VT受触发而导通,驱动风扇电动机M运转;多谐振荡器的工作频率由电阻R3和电容C2的数值决定;方波脉冲的占空比由时基集成电路IC第7脚与5脚之间的电位差决定。 [0011] After power multivibrator oscillation, 3 feet from the adjustable time base integrated circuit IC output duty cycle square wave pulse signal VT triggered thyristor is turned on, the driving operation of the fan motor M ; multivibrator operating frequency is determined by the value of resistor R3 and capacitor C2; duty cycle square wave pulse is determined by the potential difference between the base integrated circuit IC pin 7 and 5 feet.

[0012] 当室内环境温度升高时,热敏电阻RT的阻值降低,使时基集成电路IC的5脚电压上升,3脚输出方波脉冲的占空比提高,晶闸管VT的导通角增大,风扇电动机M在单位时间内通电时间变长,运行时间延长,转速加快,从而加大风量以达到降温的目的。 5-yl pin voltage integrated circuit IC increased [0012] When the indoor temperature increases, the thermistor resistance RT decreases, so that, the duty cycle square wave pulse output pin 3 increases, the conduction angle of the thyristor VT increases, the fan motor M is energized in a unit time becomes longer, the run time, to accelerate the speed, thereby increasing the air flow rate to achieve the purpose of cooling.

[0013] 反之,当室内环境温度下降时,热敏电阻RT的阻值升高,使时基集成电路IC的5脚电压下降,3脚输出方波脉冲的占空比降低,晶闸管VT的导通角变小,风扇电动机M在单位时间内通电时间变短,运行时间缩短,转速下降,从而减小风量使室内温度回升。 [0013] On the contrary, when the indoor temperature decreases, the thermistor resistance RT increases the base voltage at pin 5 of integrated circuit IC decreases, the duty cycle of the square wave pulse output pin 3 is lowered, the pilot thyristor VT angle becomes smaller, the fan motor M energization time within a unit time becomes short, the running time is shortened, the rotational speed decrease, thereby reducing the amount of the indoor air temperature rises.

[0014] 在使用时,打开电风扇电源开关后,该电路接通,室温的变化通过热敏电阻RT电阻阻值的变化来控制时基集成电路IC的5脚电压,从而间接控制3脚输出方波脉冲的占空t匕,进而影响晶闸管VT的导通角的大小,晶闸管VT的导通角增大,风扇电动机M在单位时间内通电时间变长,运行时间延长,转速加快,从而加大风量以达到降温的目的。 [0014] In use, the fan opens the power switch, the circuit is turned on, the base voltage of pin 5 of integrated circuit IC when temperature changes is controlled by the resistance change of the thermistor resistance RT, and therefore indirectly controls the output pin 3 accounting empty square wave pulse t dagger, thereby affecting the thyristor conduction angle VT size, the thyristor conduction angle VT is increased, the fan motor M energization time becomes long within a unit time, the run time, to accelerate the speed, thereby adding wind capacity in order to achieve the purpose of cooling. 晶闸管VT的导通角变小,风扇电动机M在单位时间内通电时间变短,运行时间缩短,转速下降,从而减小风量使室内温度回升。 VT thyristor conduction angle becomes small, the fan motor M becomes short energization time within a unit time, operating time is shortened, the rotational speed decrease, thereby reducing the amount of the indoor air temperature rises.

[0015] 上面以举例方式对本实用新型进行了说明,但本实用新型不限于上述具体实施例,凡基于本实用新型所做的任何改动或变型均属于本实用新型要求保护的范围。 [0015] In the above way of example of the present invention has been described, but the present invention is not limited to the particular embodiments, where the present invention based on any changes or modifications made are within the scope of the present invention as claimed.
