ELEVATOR ATMOSPHERIC PRESSURE CONTROLLER

摘要

A passenger of an elevator is released from unpleasantness caused by clogging of ears. An atmospheric pressure controller (104) controls the atmospheric pressure in an elevator cage (102) by using an atmospheric pressure regulator (105) such as an air fan or an air compressor. The atmospheric pressure controller (104) changes the atmospheric pressure in the elevator cage (102) greatly during a first period, i.e. a time zone when a departure/arrival time control section (121) departs from a departure floor (or the time arriving at an arrival floor), and a non-departure/arrival time control section (122) changes the atmospheric pressure in the elevator cage (102) slightly during a subsequent second period (or the time up to before arrival). Because of two stage atmospheric pressure control, the passenger is urged to draw air in the ears in a short time T1 in order to eliminate the clogging of the ears. The passenger can be lifted/lowered comfortably with the aid of the elevator cage (102) until he or she arrives at the arrival floor.
