Summary: | PROBLEM TO BE SOLVED: To provide an elevator device that can appropriately ventilate inside of a car not only during a normal operation but even when power failure or emergency stop, etc. occurs.SOLUTION: An elevator device includes: a ventilation hole 2 for ventilating inside of a car 10; a power source 11 for feeding electric power to the ventilation hole 2; an atmospheric pressure control device 1 for opening/closing the ventilation hole 2 and controlling atmospheric pressure in the car 10; a ventilation hole monitoring device 3 for opening/closing the ventilation hole 2 independently of the atmospheric pressure control device 1; a control contact 13 for connecting the power source 11 and the ventilation hole 2 with each other and connecting the atmospheric pressure control device 1 and the ventilation hole 2 with each other; a monitoring contact 12 for connecting the power source 11 and the ventilation hole 2 with each other and connecting the ventilation hole monitoring device 1 and the ventilation hole 2 with each other; and a ventilation hole opening/closing detection section 8 for detecting opening/closing of the ventilation hole 2. The monitoring contact 12 and the control contact 13 are connected in series. The ventilation hole monitoring device 1 opens the ventilation hole 2 via the monitoring contact 12 when the ventilation hole 2 is closed for a predetermined time.SELECTED DRAWING: Figure 1
【課題】通常運転時は勿論のこと、停電や非常停止等が発生した場合であっても、乗りかご内の換気を適切に行うことができるエレベータ装置を提供する。【解決手段】乗りかご10内を換気する換気口2と、換気口2に給電を行う電源11と、換気口2の開閉を行い且つ乗りかご10内の気圧を調整する気圧調整装置3と、気圧調整装置3とは独立に換気口2を開閉する換気口監視装置3と、電源11と換気口2を接続し且つ気圧調整装置3と換気口2を接続する制御接点13と、電源11と換気口2を接続し且つ換気口監視装置1と換気口2を接続する監視接点12と、換気口2の開閉を検出する換気口開閉検出部8を備え、監視接点12と制御接点13は直列に接続され、換気口監視装置1は、換気口2が所定時間閉じていた際に、監視接点12を介して換気口2を開く。【選択図】図1 |
