ABSTRACT:
An air cleaning machine to be used in houses, offices and so on utilizes an ultraviolet-ray sensor and a gas sensor jointly to combine the characteristics, so that the operation of the appliance becomes extremely smooth. The appliance operates almost immediately especially when a signal from a light is received. If a cigarette is lighted, for example, indoors, the air cleaning machine operates immediately to clean the air, so that the user may actually feel it. When the gas occurs even under the circumstance where the ultraviolet ray does not reach the light sensor, the normal operation is performed, thus allowing the automatic operation to be effected. Accordingly, clean air is normally provided under the optimum circumstance.
