Description

  The present invention relates to an elevator car air conditioner that suppresses wind noise generated in accordance with the movement of the car.

  In recent years, with the increase in the number of buildings, the speed of elevators also tends to increase. In the case of such a high-speed elevator, when the carriage and the counterweight pass each other, when passing through the front edge protruding from the entrance / exit of the landing to the hoistway side, or on the hoistway side surface such as equipment installed in the hoistway For example, when passing through a portion protruding from the air, the air passage cross section between the car and other devices changes suddenly, resulting in pressure fluctuations in the air. In addition, since there is no such change in the air passage cross section, the shape of the car is square, so that large air turbulence occurs at the corners of the car, causing pressure fluctuations. This is transmitted to the car as a wind noise, giving passengers discomfort and anxiety. For this reason, it has been proposed to install wind-defining covers on the upper and lower parts of the car to suppress wind noise, but such air-conditioning covers are extended upward and downward of the car, The length of the windbreak cover is set to be relatively long in order to obtain a wind noise suppression effect. Therefore, when the car is located on the top floor and the bottom floor, or for some reason, the top floor and the bottom floor. When the stop position is exceeded, there is a risk of colliding with a shock absorber installed at the upper part of the hoistway or at the lower part of the hoistway.

For this reason, conventionally, as a technique for solving this problem, a wind-conditioning cover that rectifies the wind generated by the traveling of the car, that is, a wind-conditioning body, is attached to the upper and lower parts of the car so that it can be expanded and contracted vertically. An opening is formed at the tip when the body is shortened, and wind noise is suppressed without increasing the structure of the building, and the opening is used as a scaffold for maintenance inspection of the upper and lower parts of the car. What has been made possible has been proposed (see, for example, Patent Document 1).
