Problems solved by technology

However, when the pressure in the elevator car is increased or decreased in a stepwise manner, since the pressure increases or decreases in an instant, the momentary pressure change in the car acts on the passenger, which will cause serious damage to the passenger. Discomfort or impairment of ear function

Embodiment Construction

[0020] Refer to the following figure 1 Embodiments of the elevator equipment of the present invention will be described.

[0021] The elevator car 1 that ascends and descends in the elevator passage is provided with: a pressure adjustment device 2, which increases or decreases the pressure in the elevator car 1 according to the lifting of the elevator car, so that the pressure in the elevator car is close to the air pressure in the elevator passage a pressure detection device 3, which detects the pressure in the elevator car 1; and a control device 4, which controls the pressure adjustment device 2 according to the detection pressure and the lifting position in the elevator car 1 detected by the pressure detection device , thereby increasing or decreasing the pressure in the elevator car 1 stepwise.

[0022] The pressure adjusting device 2 is a device for increasing or decreasing the pressure in the elevator car by supplying air into the elevator car 1 or exhausting air from ...

Abstract

The invention provides an elevator device capable of making the passengers sense the pressure change and having the enough time to perform the swallow action without abrupt change of pressure, when increasing or reducing the pressure in an elevator car. A pressure adjustment device (2) capable of increasing or reducing the pressure in the elevator car (1) is controlled by a controlling device (4), thus the pressure in the elevator car (1) is increased and reduced in preset time and the increased or reduced pressure is kept for preset time. The abrupt change of pressure is prevented by the above control, thus ear function obstruction due to the abrupt pressure change is alleviated and the pressure change is fully sensed by the passengers. Because the increased or reduced pressure is kept for a preset time, the passengers have the enough time to perform the swallow action and the ear obstruction feeling due to electric pressure change is eliminated and the ear obstruction feeling and discomfort feeling can be eliminated at the first opportunity.

Description

technical field [0001] The present invention relates to an elevator device and a pressure control method thereof, in particular to a method capable of alleviating the pain caused by pressure changes in the elevator car to elevator passengers when the elevator car is moving up and down at a high speed in a high-travel elevator channel. Elevator equipment for blockage and discomfort and its pressure control method. Background technique [0002] Generally speaking, when the elevator car of the elevator equipment is going up and down at high speed in the high-travel elevator passage, the sudden pressure change in the elevator car will bring a sense of ear blockage and discomfort to passengers. In order to improve these unfavorable conditions, for example, Patent Document 1 proposes a solution in which the pressure inside the elevator car is changed stepwise according to the elevation of the elevator car, thereby giving passengers time to swallow. [0003] Patent Document 1 Japa...
