PURPOSE:To release a driver and a passenger from troublesome control of a switch, to cause them to devote themeselve to safe driving, and enable comfortable driving of a vehicle, by a method wherein ON-OFF control of an air cleaner form a vehicle, such as car, is automated. CONSTITUTION:A voltage, set by a level setter 7 which is capable of arbitrarily setting the detecting level of the degree of air pollution, is compared with a voltage, proportioning the degree of pullution of air in a car room perceived by the sensor 1, by means of a comparator 6. If the input of the sensor 1 exceeds the value, a d.c. motor 9 is run, a fan 11 in an air cleaner 12 connected to a driving shaft 10 of the motor is driven to move the air in the air cleaner 12, and the air is cleaned to return it to a car room. An air cleaner 12 is functioned such that, with the fan 11 driven, the air is sucked through an air suction port 14, the air, freed of dust by means of a dust remover 15, passes through a deodorizer 16, negative ion is generated by a negative ion generator 17, and the negative ions is mixed with the air, freed of dust and offensive smell, to clean the air to return it through an air outlet 13. |
