Problems solved by technology
[0002] When a passenger uses a high-speed elevator installed in a high-rise building, for example, to descend from the top floor to the bottom floor in one go, there are cases where the passenger feels uncomfortable due to ear pressure changes due to changes in the air pressure in the compartment.
[0003] That is, the car descends to the bottom floor by accelerating, constant speed (operating at rated speed), and decelerating from the top floor. The degree of pressure discomfort becomes greater and the discomfort becomes stronger

Embodiment Construction
[0050] Embodiments of the present invention will be described below with reference to the drawings.
[0051]
[0052] figure 1 It is a diagram showing the air pressure control pattern in a stepped shape to be set in this embodiment, with the time lapse [s] from the departure floor to the stop floor as the horizontal axis and the air pressure [hPa] in the cabin as the vertical axis chart.
[0053] figure 1 (a) represents the air pressure control mode during the descending operation of the car, figure 1 (b) shows the air pressure control mode during the ascending operation.
[0054] Such as figure 1 As shown, in the descending operation, the air pressure control mode is a step shape rising to the right, on the other hand, in the ascending operation, the air pressure control mode is a step shape descending to the right, but the step shape is not different, so for figure 1 (a) and figure 1 The graphs (air pressure control mode) in (b) are denoted by the same symbols,...

Provided are a method for setting an air pressure control mode and an elevator equipped with an air pressure adjustment device, capable of setting an air pressure control mode corresponding to the lifting distance and the lifting time. A method for setting an air pressure control mode. The air pressure control mode forms an air pressure change interval in which the air pressure in a compartment is changed by an air pressure change rate B by an air pressure change amount A, which is equivalent to a kick surface, and an air pressure fixed interval in which the air pressure is not changed is equivalent to a tread surface. In this method, the time allocated to the air pressure fixed interval is C, the atmospheric pressure difference determined by the distance L of one lift is P, the lift time required for one lift is T, and the number of stages in the ladder shape is N In the case of , find N and C that minimize the index value of ear pressure discomfort calculated by the formula including (number 1), and set it by using A=P / N, B=P / {T-C· (N‑1)} The calculated A, B and the obtained N and C form the air pressure control mode.
Description
technical field [0001] The present invention relates to elevators and the like, in particular to the air pressure control technology in the compartment. Background technique [0002] When a passenger uses a high-speed elevator installed in a high-rise building etc. to descend from the top floor to the bottom floor in one go, for example, the passenger may feel uncomfortable due to ear pressure changes due to changes in the air pressure in the compartment. [0003] That is, the car descends to the bottom floor by accelerating, constant speed (operating at rated speed), and decelerating from the top floor. The degree of pressure discomfort becomes larger and the discomfort becomes stronger. [0004] The elevators installed in the so-called super high-rise buildings that have appeared in recent years have very long lifting strokes. In addition, because the elevators have achieved ultra-high-speed lifting speeds to improve transportation efficiency, the discomfort caused by ear...
