Problems solved by technology

[0005] However, for elevators that are carried out at high speed in narrow hoistways, corresponding to the hoisting floors, there are narrow parts such as hall thresholds in the hoistway. Aerodynamic noise (バフ sound), which brings discomfort to passengers in the car and passengers waiting in the elevator hall

Embodiment Construction

[0042] First, before describing the embodiment of the present invention, a low-to-high speed elevator is taken as an example to explain in detail the mechanism of aerodynamic noise when the elevator travels.

[0043] For low-to-high-speed elevators, a drop prevention plate known as a "baffle" is installed on the side of the waiting hall at the lower end of a box-shaped passenger car. The fall prevention plate extends a predetermined length from the edge of the car door toward the descending direction.

[0044] For a low to high speed elevator with such a shape, while measuring the position of the car, the results obtained by observing the aerodynamic noise generated during travel are figure 1 On display.

[0045] figure 1 In the middle, the horizontal axis represents time, and the vertical axis represents the magnitude of noise. When the passenger car is lowered at a predetermined speed, the moment the tip of the fall prevention plate passes through the narrow part such as the door ...

Abstract

The present invention provides an elevator device, wherein an airflow generation device (10) is set on a surface of an end part of at least one of upper and lower end parts of a car (51) that ascends and descends in an elevation path (35), the surface facing a platform of the elevation path, and air power noise generated by the car (51) passing through a narrow part (37) of the elevation path (35) is reduced by airflow discontinuously generated by the airflow generation device (10) in an identical frequency of a peeling flow from the upper end part of the car synchronously.

Description

Technical field [0001] The embodiment of the present invention relates to an elevator apparatus including an air flow generating device. Background technique [0002] Along with the high-rise building, the requirements for elevators as vertical transportation mechanisms are also increasing. One of them is the high speed of elevators. In addition, the rated speed of the elevator is defined as the "maximum speed when the car is ascending under the load" in accordance with the Building Standards Act. If elevators are classified according to speed, they can be divided into the following four categories: elevators with a rated speed of less than 45m per minute are specified as "low speed"; elevators with a rated speed of 60m~105m per minute are specified as "medium speed"; and above 120m per minute The elevators in China are specified as "high-speed"; elevators above 360m per minute are specified as "super high-speed". [0003] As the rated speed of the elevator reaches more than 400...
