れが断続的に変動する現象が生じる。That is, in a conventional general elevator, FIG.
The hoistway 1 car 2 of the elevator moves up and down as shown in, but now traveling car 2 in the illustrated upward direction of the elevator to the upper pressure P 1 and the lower pressure P 2 within the hoistway 1, P 1
> A relation of P 2. Then, at this time, the airflow is diverted in the front direction of the car 2 of the elevator, that is, the car door side and each of the other side surfaces in the direction of the arrow shown in the drawing. Since the air flow is small compared to the others, the flow of the air flow due to the above-described pressure difference becomes faster in this portion, and in addition, the phenomenon that the flow of the air flow intermittently fluctuates due to the influence of the uneven portion in the hoistway 1 occurs.

When the air flowing along the edge of the sill 5 passes through the edge of the sill 5, air separation occurs, and a horseshoe-shaped vortex 6 occurs at the upper part of the sill 5. This causes the generation of wind noise.

タのかご２内の乗客に不快感を与えることがあった。As described above, the wind pressure, wind noise, and wind flow in the hoistway cause noise. However, as the speed of the elevator increases, the wind pressure, the wind noise, and the wind gradually increase. In some cases, the light propagates from the gap between the elevator car 2 and the car door 3 into the elevator car 2, causing discomfort to the passengers in the elevator car 2.

敷居５の正面に当接させている。The air conditioner 7 is composed of a pair of left and right air conditioners 7A and 7B which are opposite to each other, and is disposed on the left and right sides of the elevator car 2. Each of the left and right air conditioners 7A and 7B is formed in an L shape having a front part 7a and a side part 7b, and the front parts 7a and 7a have widths that cover the car doors 3 when opened. To prevent passengers from getting in and out of the doorway. In addition, the left wind regulating body 7A and the right wind regulating body 7B have the lower inner surfaces of the front portions 7a, 7a abutting against the front of the threshold 5 as shown in FIG.

ことができる。Next, the operation of the embodiment configured as described above will be described. Since the lower inner surfaces of the front portions 7a and 7a of the left and right air conditioners 7A and 7B are in contact with the front surface of the threshold 5, air separation points at the upper corners of the threshold 5 can be eliminated, and the elevator can be eliminated. When the car 2 travels downward, the air flowing along the apron 4 flows almost linearly as shown by the arrow in FIG. 2, and the horseshoe-shaped vortex 6 generated at the upper part of the conventional sill is generated. Without generating wind noise. In addition, the noise in the hoistway that enters through the gap between the elevator car 2 and the car door 3 is reduced by the left air conditioner 7A,
Soundproofing can be achieved by covering the car door 3 with the right wind regulating body 7B.
