PROBLEM TO BE SOLVED: To enable a driver to instantaneously and safety check an air quality level even during driving while it is advantageous to install an air cleaner for sucking air in a car on a rear seat side.SOLUTION: The air cleaner includes a contamination concentration detection sensor 21 for detecting an air quality in a car, a microcomputer 20 for controlling an air-conditioning operation, and a display part 23 for displaying the degree of contamination by emitting light on a riding space side. The microcomputer 20 includes a calculation part 20a for calculating the degree of contamination in the car detected by the contamination concentration detection sensor 21, and a control unit 20b for controlling the operation of the air cleaner. The control unit 20b instructs the display part 23 to light or flash based on the degree of contamination calculated by the calculation part 20a. Thus, a driver can check the flashing of the display part 23 through a rearview mirror, and an occupant can check the degree of contamination in the riding space by flashing light according to the degree of contamination.SELECTED DRAWING: Figure 3 |
