が形成されている。In the figure, (1) is the elevator-hoistway, (2) is the main rope (3
) is a high-speed elevator suspended by a hoistway (1).
The car compartment (4) is an exterior body provided at the upper and lower ends of the car compartment (2), with the base located on the outer edges of the upper and lower ends of the car compartment (2), and the tip located on the outer edge of the upper and lower ends of the car compartment (2). 2) A tapered vertical surface (4a) consisting of an inclined surface located near the center line
is formed.

あるが、高価なものとなるという問題点がある。[Problem to be solved by the invention] In the conventional elevator car air conditioning device as described above,
Since the exterior body (4) is provided above and below the cage (2),
As shown in Figure 5, the main laminar air flow A can be rectified, but the air flow causes separation at the inflection point B of the exterior body (4), and the separated air flow flows to point C. Due to redeposition, this energy hits the exterior body (4) or the outer wall of the cab (2), causing a problem in that noise is generated. Furthermore, it is effective to prevent noise by pasting sound insulating material, vibration damping material, etc. on the wall of the car room (2) or the inside of the exterior body (4), but there is a problem in that it is expensive. .
この発明は上記問題点を解決するためになされたもので

エネルギーを奪う結果、乱流の速度が上昇してはく離点
を後方に流し去って。[Function] In this invention, since a large number of hemispherical recesses are formed on the outer surface of the exterior body and the cab, the airflow in these parts becomes turbulent, and the vortices in this turbulence cause the flow on the outside. As a result, the velocity of the turbulence increases and the separation point is swept away backwards.
再付着力は小さくなる。The reattachment force becomes smaller.

turbulent flow (9) due to the large number of recesses (7).
). Then, the vortex (9a) in the turbulent flow (9) absorbs kinetic energy from the air flow (8) outside of it, and the speed of the turbulent flow (9) increases. As a result, the separation point is washed away backwards, reducing the reattachment force, and the cage (
2) The noise transmitted inside is reduced.

This is shown in Japanese Patent No. 5778. This invention provides an elevator car (2a) which is not a rotating body but a non-rotating moving body.
The hemispherical diameter of the recess (7) corresponds to the speed of the car (2a), and the low-frequency noise range ( 200
The aim is to realize a quiet high-speed elevator by preventing noise of up to 500 Hz.
