PURPOSE:To improve the degree of freedom in installation performance by installing a transmission means for transmitting radio signal by the output of a smoke sensor for detecting the contamination of the air in a compartment onto a ceiling part by utilizing a room lamp wiring in the ceiling part in the car compartment and operating an air cleaner by the radio signals. CONSTITUTION:A remote control part 7 is installed by utilizing a room lamp wiring on the ceiling part in the car compartment 2 of an automobile 1, and an air cleaner device body 4A on a rear part shelf 3 is ON/OFF-controlled by the radio signal generated from the remote control part 7. In the remote control part 7, a transmission means 14 which is ON-operated in the case when the noise wave of an alternator, etc., which is superposed with a power line is detected during the engine operation is installed in the remote control part 7, and the transmission means 14 allows an ultrared ray luminous diode 72 to flash through a transmission control part 41 when a smoke sensor 50 detects the smoke in the car compartment 2 and generates the radio signal of the ultrared ray. The radio signal is received by a receiving means in the air cleaner body device 4A, and an air cleaner is operated. |
