AI Technical Summary

Problems solved by technology

[0005] However, for an elevator running at high speed in a narrow hoistway, corresponding to the hoisting floor, there are narrow parts such as hall thresholds in the hoistway.
There is a problem that when the passenger car passes through this narrow part, local aerodynamic noise is generated, which brings discomfort to the passengers in the car and passengers waiting in the waiting hall

Embodiment Construction

[0033] (first embodiment)

[0034] Figure 1A , Figure 1B It is a figure showing the structure of the elevator apparatus of the 1st Embodiment of this invention, Figure 1A is the front view of the passenger car, Figure 1B It is a side view of the passenger car running in the hoistway.

[0035] The elevator of this embodiment includes a passenger car 11 installed in the hoistway 10 . The passenger car 11 is driven by a winch not shown in the figure, and moves up and down in the hoistway 10 through the cable 12 . On the front of the passenger car 11, a car door 13 is provided, and the car door 13 can slide freely on a threshold 14 in the horizontal direction.

[0036] A plate-shaped panel 15 having a predetermined length is attached to a lower portion of the sill 14 of the car door 13 in the descending direction. This panel 15 is commonly referred to as a "baffle", and is used as a fall prevention plate.

[0037] On the other hand, on the side of the hall 20 of each floo...

Abstract

The present invention provides an air-stream generating device of an elevator. The air-stream generating device is provided with a abrasion wear detection circuit (40), current flows through at least one electrode (32) of two electrodes (32, 23) of an air-stream generating device (30), the value of the current is measured by a galvanometer (44), when the current value measured by the galvanometer (44) is below a preset value, a control device 50 decides that the abrasion wear of the electrode (32) needs replacing and notifies a notifying part (51) to notify the situation.

Description

technical field [0001] The invention relates to an air flow generating device used in an elevator device. Background technique [0002] Along with the high-rise buildings, the elevators installed in them are also developing at high speed. On the other hand, when the rated speed of the elevator reaches 400 m / min or more, there is a problem of aerodynamic noise due to the airflow around the passenger car (see, for example, Non-Patent Document 1). [0003] In addition, the rated speed of an elevator is defined as "the maximum speed when the car is raised by a load" in accordance with the Building Standards Act. If the elevator is classified according to the speed, it can be divided into the following four categories: the elevator with a rated speed below 45m (meter) per minute is specified as "low speed"; the elevator with a rated speed of 60m to 105m per minute is specified as "medium speed"; Elevators above 120m per minute are defined as "high speed"; elevators above 360m p...
