PURPOSE:To early clean the pollution by disposing smoke and gas detecting sensors to both end parts of a main body and providing the rail enabling the main body to move under the ceiling surface in a room. CONSTITUTION:The smoke and gas detecting sensors 9, 9a disposed to both end parts of main body detect the place where smoke or pollution is generated in the room. According to the difference between the values detected by the detecting sensors 9, 9a, a control part 12 controls the main body to move to the direction having larger detected value. The main body 1 is moved along the rail 15 disposed under the ceiling surface by rollers 11 driven with the positive or negative revolution of a driving motor. Consequently, before the smoke or the polluted air is dispersed to the other place, the air is early cleaned on the spot. |
