ELEVATOR DEVICE

摘要

An elevator device has an elevator car (1) moving vertically; a fan (3) having an air suction opening (3a) and an air discharge opening (3b); ducts (11-13) each having one end connected to the elevator car (1), the air suction opening (3a), and the air discharge opening (3b); an air volume adjusting means (20) having connected thereto the other end of each of the ducts (11-13) and adjusting the volume of air sucked into and discharged from the inside of the elevator car (1), the air volume adjusting means (20) performing the adjustment by changing the volume of air bypassing the inside of the elevator car (1) and flowing from the air discharge opening (3b) to the air suction opening (3a) of the fan (3); and a controlling means (10) for controlling the air volume adjusting means (20) to adjust the air pressure in the elevator car (1) to a set air pressure. The air pressure in the elevator car (1) can be adjusted to the set air pressure even if the difference between the set pressure and the air pressure outside the elevator car (1) is small.
