Fig. 2 is a kind of control method flow chart of energy-saving scavenging fan device of the present invention.
Specific implementation mode
The present invention is further elaborated by the way that a preferable specific embodiment is described in detail below in conjunction with attached drawing.
As shown in Figure 1, a kind of energy-saving scavenging fan device of the present invention, including：Microcontroller, the temperature being connect with the microcontroller
Acquisition module, timing function module, mode control module, alarm module, display module, relay, and connect with relay
Ventilation fan.
Temperature collecting module for acquiring outdoor temperature T1 and indoor temperature T2 in real time.
Temperature collecting module includes two temperature sensors, and wherein any one temperature sensor is for detecting outdoor temperature
T1, another temperature sensor is for detecting indoor temperature T2.Two temperature sensors are by its collected temperature information to list
Piece machine and display module transmission.In the present embodiment, the model DS18B20 of two temperature sensors.The model of microcontroller
STC89C51RC.Display module uses the liquid crystal display of model LCD1602.Display module also with timing function module phase
Even, for showing timing and outdoor temperature T1 and indoor temperature T2.
The relay is connected with the motor of ventilation fan.To the shadow of circuit when start-stop and power-supply fluctuation to avoid motor
It rings, input and output are all made of electromagnetic isolation.Output controls the start-stop of motor by relay, to control ventilation fan whether work
Make.
In the present embodiment, ventilation fan is a kind of through mode total-heat exchanger, and heat exchanger is to wait wind to gas and exhaust
Amount, so being not in draught, and pass through the effect of heat exchanger, the epidemic disaster and room air ten of fresh air
Tap is close, will not generate uncomfortable feeling because of ventilation completely.The ventilation fan is using small DC common in the market
The fan of machine driving.
