Indoor air quality sensor is with outdoor air sensor by serial ports with the microcontroller communication of master control borad.Fresh air wind
Machine is controlled with the switch of return air fan by relay.MOTOR-SET-1 with MOTOR-SET-2 be high level when, blower is opened
Begin rotation, MOTOR-SET-1 with MOTOR-SET-2 be low level when, blower stops working.EC1 leads to EC2 output pwm signal
The width of high level in a pulse clock is crossed to control the revolving speed of blower.But since the level of blower is 12V, single-chip microcontroller is defeated
Out be 5V, so increase a DZ1 with two 12V of DZ2 voltage-stabiliser tube.Blower interior has a Hall element, every revolution
A dextrorotation square wave can be generated, D1 filters out the negative half part of dextrorotation square wave with D2.The amplitude of this dextrorotation square wave is 12V, but
The highest pressure resistance for being single-chip microcontroller is 5V, then passes through two resistance to divide.Single-chip microcontroller passes through the two high electricity of detection dextrorotation square wave
Time interval between flat, detects the revolving speed of blowing machine.If can't accept high level in certain time always, motor is defaulted
Damage, OLED display screen prompts fault code, and sends fault cues to mobile phone.
In conclusion structure of the invention principle is simple, intelligence degree is high, inner-outer circulation handoff functionality is had, according to room
Outer air quality intelligently switches inner-outer circulation operating mode.Low temperature is easy to cause heat exchanger and blower to generate frosting, influences
Machine uses safe and service life；Outdoor serious haze and sandstorm weather can reduce the service life of strainer, increase
The frequency of user's replacement strainer；When outdoor sensor detects the too low or outdoor PM2.5 excessive concentration of outdoor temperature, meeting
Interior cycle operation is automatically switched to, the service life of strainer is extended and protects the service life of machine.When user opens air-conditioning
Or after heating, user can manual switching inner-outer circulation operating mode, interior circulating purification mode can prevent energy loss, outer circulation
It can guarantee there are enough fresh airs in room simultaneously in purification air.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
