Soot inflow blocking device for automobile air conditioner

摘要

A soot sensing unit 10 installed at an outside air inlet of the air conditioner for sensing soot and converting it into an electrical signal and outputting the electrical signal; A microcontroller 20 for outputting a signal for shutting off the soot when the soot is sensed and an actuator 30 for shutting off the inflow air according to a signal inputted from the microcontroller 20, There is provided a smoke inflow / outflow prevention device for an air conditioner of an automobile air conditioner, which is capable of keeping indoor air pleasant by shutting off the actuator when the soot is introduced into the vehicle by using the soot sensor at the outside air inflow port.
