PROBLEM TO BE SOLVED: To provide a ventilation fan dust removal device for an elevator which can sufficiently remove dust accumulated on a ventilation fan without increasing a load to a control circuit and the other in-car apparatus, and can favorably maintain an environmental sanitary condition in a car.SOLUTION: In this device, when fans 2a to 2n arranged at elevators 1a to 1n are controlled and set by a control terminal 17a which is possessed by a maintenance person 19, an operation command part 13 operates the fans 2a to 2n for prescribed times at reverse rotation with respect to their rotation directions, and removes dust as a comparison result of a comparison part 12 in an operation command control part 7 in a monitoring center 14 when the fans 2a to 2n show thresholds not smaller than first thresholds indicating the prescribed times, and also when stop positions of cars show second thresholds indicating prescribed floors, and operates the fans at forward rotation (prescribed rotation directions) after the lapse of the prescribed times, and when the fans 2a to 2n show thresholds smaller than the first thresholds, or show thresholds not smaller than the first thresholds, and show thresholds exceeding the second thresholds, issues commands to control devices 3a to 3n so that the fans are operated at forward rotation.SELECTED DRAWING: Figure 1
【課題】制御回路やその他の乗りかご内機器への負荷を増加させずに換気ファンに堆積した塵埃を十分に除去でき、乗りかご内の環境衛生状態を良好に維持できるエレベータ用換気ファン塵埃除去装置を提供する。【解決手段】この装置は、エレベータ1a〜1nに設けられたファン2a〜2nが保守員19の所持する制御端末17aで制御設定されると、監視センタ14内の動作指令制御部7において、動作指令部13が比較部12の比較結果として、ファン2a〜2nが所定の期間を示す第1の閾値以上、且つ乗りかごの停止位置が所定階を示す第2の閾値以下であればファン2a〜2nの回転方向を逆回転で所定時間稼動させて塵埃除去を行うと共に、所定時間経過後に正回転(所定の回転方向)で稼動させ、ファン2a〜2nが第1の閾値未満である場合や、第1の閾値以上、且つ第2の閾値超過の場合には正回転で稼動させるように、制御装置3a〜3nへ動作指令する。【選択図】図1
