PROBLEM TO BE SOLVED: To provide an elevator which can exhaust smoke further efficiently with a simple structure, and which can prevent a temperature rise due to smoke which has intruded in a hoistway and fire from affecting a control board of the elevator installed inside the hoistway.SOLUTION: An elevator includes a hoistway, a suction device, a control board, an exhaust door and a switching control unit. In the hoistway, a hoisting machine for ascending/descending an elevator car is provided on a hoistway wall. The suction device can suck the outside air which is different from the air on the landing side of the car into the hoistway, and at least one is provided. The control board is provided so that a lower end is positioned at a position higher than a floor surface of the landing on the highest floor out of the landings, and controls the operation of the elevator. The exhaust door can open/close an exhaust port provided on the hoistway wall so that at least a part of the side surface of the control board faces a space in which the outside air exists. The switching control unit controls a suction operation of the suction device and an opening/closing operation of the exhaust door.SELECTED DRAWING: Figure 1

    【課題】シンプルな構成で、より効率的な排煙が可能であるとともに、昇降路内に侵入した煙や火災による温度上昇が、昇降路内に配置されたエレベータの制御盤に影響しないようにできるエレベータを提供する。【解決手段】実施形態のエレベータは、昇降路と、吸気装置と、制御盤と、排気扉と、切替制御部と、を含む。昇降路は、エレベータの乗りかごを昇降させる巻上機が昇降路壁に配置されている。吸気装置は、昇降路に乗りかごの乗り場側の空気とは異なる外気を吸気可能で少なくとも1つ設けられている。制御盤は、乗り場のうち最上階の乗り場の床面より高い位置に下端が位置するように配置されて、エレベータの運行を制御する。排気扉は、制御盤の側面の少なくとも一部が外気の存在する空間に臨むように昇降路壁に設けられた排気口を開閉可能とする。切替制御部は、吸気装置の吸気動作と排気扉の開閉動作を制御する。【選択図】図1
