Elevator with air pressure control device inside the elevator car

Abstract

The invention provides an elevator with a lift car air pressure control device. The air pressure control device changes air pressure in a car lift when an elevator rises, thereby allowing passengers to realize air pressure change before the air pressure in the lift car changes greatly and providing time for the passengers to swallow. The elevator possesses a lift car air pressure control device which controls the air pressure in the lift car in dependence on a staged air pressure changing mode of the rising of the elevator lift through the inhalation and exhaust of an air blower in the lift car. The elevator is provided with the air blower, an air volume switching device, an air volume adjusting device and a control device. The air volume switching device is used for performing staged switching on the air volume going in and out of the car lift; the air volume adjusting device is used for continuously changing the air volume air volume going in and out of the car lift; the control device controls the air blower, the air volume switching device, and the air volume adjusting device in dependence on elevator operation information.

Description

technical field [0001] The invention relates to an elevator with means for controlling the air pressure inside the elevator car. Background technique [0002] When taking an elevator in a high-rise building, as the elevator car goes up and down, the air pressure in the elevator car changes, and sometimes it feels like earplugs. This feeling of ear plugging is called "ear plugging sensation" and it disappears when the ear tubes open naturally or when swallowing (swallowing saliva). Especially during descending operation, due to the increase in air pressure, the ear tube will not open naturally from the structure of the ear, so it is best to consciously swallow saliva to open the ear tube before feeling the pain, so as to prevent it from happening. Ear plug feeling. [0003] As a prior art, for example, Patent Document 1 discloses a technology that can make passengers aware of air pressure changes before the air pressure in the elevator car changes significantly, and in orde...

AI Technical Summary

Problems solved by technology

[0011] In the above-mentioned patent document 1, the method for realizing the target air pressure change mode is discussed, but it does not fully discuss the air pressure control device for realizing the stepwise air pressure change mode

[0012] In addition, in the air pressure control device disclosed in the above-mentioned Patent Document 2, since the clearance of the elevator car is not taken into consideration, it cannot be applied to an actual elevator car having clearances such as elevator door portions.

In addition, when the air pressure is changed step by step, because the method of changing the air pressure rapidly is adopted, no consideration is given to how to adjust the air pressure change rate to an appropriate size

[0013] On the other hand, in the air pressure control device disclosed in Patent Document 3, the air volume cannot be quickly switched in a short time because no consideration is given to changing the air pressure in stages.

Therefore, although it is hoped to form a periodic air pressure change pattern, it can only form a waveform with a flat angle of the upright part and the corner of the periodic air pressure change, resulting in an inconspicuous change in air pressure, and passengers cannot clearly realize the change in air pressure. Short rest periods for swallowing movements, unsatisfactory
