<P>PROBLEM TO BE SOLVED: To suppress the entry of external contaminated air into a car 2 and a living room. <P>SOLUTION: A plurality of fan 10-50 groups are installed in the car 2 and combined to solve a problem. During door closing waiting or travel toward a lobby floor, fans 21 and 22, and 41-43 are operated, and purification in the car is performed. When users get in from the lobby floor, external contamination factors adhered to the passengers are blown away to the lobby side by the fan 30 group (31-33). During travel to the living room floor, the passengers in the car 2 are purified. When the elevator arrives at the living room floor, the door opening is prevented from discharging the contaminated air in the car to the living room floor by a fan 10 such as an air curtain. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
