PURPOSE:To enable the stable detection and purification of pollution with a simple treatment circuit by providing an air purifier which drives an air cleaner, determining the opening of a roof panel according to outside air temperature, humidity, vehicle speed, incident rays and the like, for example, by pulling an ash tray. CONSTITUTION:As an ash tray is pulled to the service position, switches 341- 344 are closed to turn an input port Ao to the earth level 0. Then, a microprocessor MPU reads set indications of the roof panel, the air cleaner and the air conditioner and driving indication for the wiper on key switches K11- K55 at a specified timing. Subsequently, detected values of the outside air temperature, the humidity and the inside air temperature of sensors 31-33 are read thereinto as digital data with A/D conversion thereof. Then, they are amplified and binary coded 475 and binary-coded outputs thus obtained, signal levels of the vehicle speed at input ports Ao and V1-V3 are referenced with contents of an output register to perform the opening/closing control of the roof panel, the drive stoppage of the air cleaner 37 and the drive stoppage of the air conditioner 36. |
