发明名称 Elevator apparatus
摘要 An elevator apparatus includes an elevator car; an air blower including an air inlet and an air outlet; ducts each having one end individually connected to the elevator car, the air inlet and the air outlet; intake and exhaust air volume adjusting means having the other end of each of the ducts connected thereto, which adjusts an intake and exhaust volume of air in the elevator car by varying a volume of air that bypasses the car to flow from the air outlet to the air inlet of the air blower; and control means that controls the intake and exhaust air volume adjusting means, to adjust air pressure within the car to set air pressure. The elevator apparatus adjusts air pressure within the elevator car, even when there is a small differential pressure between the set air pressure within the car and an air pressure outside the car.

主权项 1. An elevator apparatus comprising: an elevator car that moves upward and downward; an air blower that includes an air inlet and an air outlet; a plurality of ducts including a first duct having one end connected to the elevator car, a second duct having one end connected to the air inlet of the air blower, and a third duct having one end connected to the air outlet of the air blower; an intake and exhaust air flow adjuster which adjusts intake flow to and exhaust flow from the elevator car in respective modes through the first duct by varying a flow of air that bypasses the elevator car, the bypass flow flowing from the air outlet of the air blower through the intake and exhaust air flow adjuster to the air inlet of the air blower, the intake and exhaust air flow adjuster comprising a plurality of ports, wherein three of the plurality of ports are connected to another end of each of the first duct, the second duct and the third duct, respectively, and the plurality of ports includes a fourth port in direct fluid communication with ambient; and a controller that controls the intake and exhaust air flow adjuster, to control an air pressure within the elevator car to a set air pressure.
