PURPOSE:To obtain a smoke removing machine for a sitting room, by so constituting that an upper cylinder with a changeable built-in smoke removing device is attached on the upper part of a fan and is arranged by giving a smoke sucking leading gap between an upper opening of the upper cylinder and a ceiling so that air containing smoke is sucked in for removal of the smoke and is blown out to the lower part. CONSTITUTION:Indoor air flows like R1 R2 through a rotation of a wafer 8, smoke, such as smoke of a tobacco contained is separated and removed from the air while the air is passing through a smoke removing device 4 and the air is discharged into a room. In this instance, a gap (H) between a main body 10 of a smoke removing machine and a ceiling 1 is set at approximately 10-40cm so that a strong smoke suction flow is generated in the vicinity of the upper opening according to a size of the main body of the smoke removing machine 10 and absorptivity. With this, air sojourning on the surface of the ceiling in a concentrated state and having a remaining smoke of a tobacco is sucked effectively, which is discharged to the lower part after the smoke has been removed and indoor air can be made to return to an upper direction. In this manner, smoke removal can be done effectively. |
