Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-speed elevator installed in, for example, a skyscraper, and more particularly to an air conditioning device for reducing wind noise during running.

[0002]

2. Description of the Related Art In recent years, with the increase in the height of buildings, the speed of elevators installed therein has been increased. However, as the speed of elevators has increased, it has been found that wind noise caused by eddy currents around a car becomes a noise source that is uncomfortable for passengers.

Generally, an elevator car is composed of a substantially rectangular parallelepiped car part and, from a safety standpoint, a thin plate-like car floor apron having a width equal to or larger than an entrance / exit width provided at the leading end of the car floor. And has a structure as shown in FIG. Here, in the figure, 1 is a car, 2 is a car floor apron, and 3a is a hoistway wall.

[0004]

As a result of investigating the gas flow around the car of the elevator having the above-mentioned structure, as shown in FIG. 4, when the car 1 descends, the car A large vortex 4 in the shape of a horseshoe found in the flow around an ordinary blunt body is formed in the lower part of 1, and a vertical vortex 5 is formed at both ends of the car floor apron 2 so as to wrap around the both ends. I found out. The vertical vortices 5 are generated when stagnant high-pressure gas in the lower portion of the car 1 wraps around toward the front of the car floor apron 2 having low pressure.
In addition to the above vortex 4 and vertical vortex 5, it has been found that the gas flows toward the wider side near the front part of the car door as indicated by reference numerals 6a and 6b due to the influence of the surface close to the hoistway wall 3a.

It has been found that wind noise is generated due to the complicated vortex flow around the car as described above, which is a large noise source. The space around the car door is narrow with the hoistway wall 3a,
Moreover, since it is difficult to improve the sound insulation performance because it has many mechanical parts such as a door opening / closing mechanism, noise due to wind noise increases by several dB in the car, which gives passengers an unpleasant feeling.

Therefore, an object of the present invention is to provide an air conditioner for an elevator that suppresses and reduces vortex flow around a car and reduces wind noise generated by the vortex to improve riding comfort.

[0007]

In order to achieve the above-mentioned object, the present invention comprises a car that moves up and down in a hoistway,
At least the lower part of the car on the surface close to the hoistway wall of the car is equipped with an air conditioning plate formed by bending the widthwise ends inward.

[0008]

With the air conditioning plate, complicated eddy currents generated around the car are suppressed / reduced, wind noise is reduced, and riding comfort can be improved.

The distance X to the hoistway wall 3a on the side is 125 mm or less according to the regulations, and the distance to the hoistway wall 3b facing the side surface of the car 1a (or the hoisting direction facing the side surface of the car 1c). The distance Y from the road wall 3c is also narrow due to the restrictions of the building.

Since the car 1a is disposed at the left end, the front face and the left side face are close to the hoistway walls 3a and 3b, respectively. Therefore, the air-conditioning plate 10A having the air-conditioning plate 10A attached to the upper part and the air-conditioning plate 11A attached to the lower part has a front face part 12a facing the hoistway wall 3a and a side face part 12b facing the hoistway wall 3b, which are orthogonal to each other.

Therefore, the air conditioning plate 10B is attached to the upper part and the air conditioning plate 11B is attached to the lower part. The air conditioning plate 10B has a front surface portion 13a facing the hoistway wall 3a, and both end portions 13b and 13b of the front surface portion 13a are bent inward. The air conditioning plate 11B has a front portion 16 facing the hoistway wall 3a.
a, and both ends 16b, 16b of the front part 16a are bent inward.

Further, since the car 1c is disposed at the right end, the front and right sides are close to the hoistway walls 3a and 3c, respectively. Therefore, the air conditioning plate 10C is on the top and the air conditioning plate 11 is on the bottom.
Attach C respectively. The air conditioning plate 10C includes a front surface portion 14a facing the hoistway wall 3a and a side surface portion 14 facing the hoistway wall 3C.
b, and these are arranged so as to be orthogonal to each other, and are integrated with each other to form an end portion 14c of the front surface portion 14a and an end portion 14d of the side surface portion 14b.
Bend inward. The air conditioning plate 11C includes a front surface portion 17a facing the hoistway wall 3a and a side surface portion 17b facing the hoistway wall 3C.
And the end portions 17c of the front surface portion 17a and the end portions 17d of the side surface portions 17b are bent inward.
