If the wind conditioned cover 5 is not at the position where the wind conditioned cover 5 is raised at high speed in step S4, the process proceeds to step S12, and the wind conditioned cover 5 is moved upward with respect to the cab 1 and placed at the position raised at high speed. The operation described above is performed.

  On the other hand, if the movement command to the cab 1 is not an ascending command in step S2, that is, if it is a descending command, the process proceeds to step S13. In step S13, if the moving floor N up to the stop floor is larger than the high-speed descent determination reference floor N1 that is determined in advance so as to perform the high-speed descent of the cab 1, the process proceeds to step S14. If it is determined in step S14 that the conditioned cover 5 is moved downward with respect to the cab 1, that is, if the conditioned cover 5 is at a position where the conditioned cover 5 is lowered at a high speed, the process proceeds to step S15, where the cab 1 is lowered, After the elapse of time, the process proceeds to step S16, and the descending speed V of the cab 1 becomes constant. Then, when the car room 1 that is descending at a constant speed approaches the destination floor, the process proceeds to step S17, and when the descending speed V of the car room 1 decreases to less than a predetermined speed V1, the process proceeds to step S18. If it is determined in step S18 that the next stop floor is the lowest floor, the process proceeds to step S19, and since the wind control cover 5 is at a position where it is rapidly lowered, the process proceeds to step S20. In step S20, after the wind regulation cover 5 is moved upward with respect to the car room 1 so that the lower part of the wind regulation cover 5 does not come into contact with other equipment or the like installed at the bottom of the hoistway, the process proceeds to step S11, and the elevator Is stopped. If the next stop floor is not the lowest floor in step S18, the wind regulation cover 5 is not moved upward, and the process proceeds to step S11, where the elevator is stopped.

  If the moving floor N up to the stop floor in step S13 is less than the high-speed descent determination reference floor N1 determined in advance so that the car room 1 is moved down at high speed, and if it does not go down at high speed, the moving conditioned cover 5 is positioned. Regardless, the process proceeds to step S15 to perform the operation described above. In this case, if the conditioned cover 5 is not at the position where it is rapidly lowered in step S19, the conditioned cover 5 is not moved and the process proceeds to step S11 and the elevator is stopped. In step S14, if the wind regulation cover 5 is not at the position where it descends at a high speed but the process proceeds to step S21 and the wind regulation cover 5 is moved downward with respect to the cab 1 and is located at a position where it is lowered at a high speed, step S15. The operation described above is performed.

  According to the first embodiment described above, since the wind regulation cover 5 is moved in the up-and-down direction by the wind regulation cover driving means 10, the upper and lower portions of the streamlined tapered wind regulation cover 5 are formed. The noise generating part due to the collision with the air flow consisting of is moved away from the cab 1. For this reason, the quietness in the cab 1 can be improved.
