Abstract

An elevator and an air pressure control method of the elevator are disclosed to improve air pressure control effects. The elevator (1) comprises a passenger car (120), a wind blowing part (4) for ventilating, a wind blowing part (5) for suction and a controller. The wind blowing part (4) for ventilating is provided with a fan driven to rotate, and when the fan is driven to rotate forwardly, air in the passenger car (120) is discharged to the outside. The wind blowing part (5) for suction is provided with a fan driven to rotate, and when the fan is driven to rotate forwardly, air is inhaled from the outside to the passenger car (120). The controller allows the other of the wind blowing part (4) for ventilating and the wind blowing part (5) for suction to act when one of the wind blowing part (4) for ventilating and a wind blowing part (5) for suction acts.

Description

technical field [0001] The present invention relates to an elevator and an elevator air pressure control method capable of controlling the air pressure inside the car in accordance with the lifting motion of the car. Background technique [0002] In recent years, along with the increase in the height of building structures, the ascending and descending distance of the car of the elevator has become longer, and the ascending and descending speed of the car has also become faster. When the lifting distance of the car becomes longer and the lifting speed becomes faster, the air pressure change in the car also becomes larger. In addition, once the air pressure in the car changes sharply, it will cause ear plugs (Japanese: 耳话まり) and discomfort to passengers. [0003] In order to improve such disadvantages, for example, there is such a technique described in Patent Document 1. The following technology is described in Patent Document 1, including: a blower for air intake, which s...
