  Specifically, for example, when the floor registered by the registration unit 101 matches the stop floor of the car 3 calculated by the stop floor calculation unit 103, the drive control unit 104 operates the drive motor 20C. A control command (hereinafter referred to as an operation command for convenience) to be output to the air curtain device 20, and the floor registered by the registration unit 101 and the stop floor of the car 3 calculated by the stop floor calculation unit 103 are one. If not, a control command for stopping the drive motor 20C (hereinafter referred to as a stop command for convenience) is output to the air curtain device 20.

  Next, the control process of the air curtain device 20 by the control panel 10 according to the first embodiment of the present invention will be described in detail with reference to the flowchart of FIG.

  FIG. 4 is a flowchart showing a flow of control processing of the air curtain device by the control panel shown in FIG.

  In the control panel 10 according to the first embodiment of the present invention, the drive control unit 104 inputs information on the stop floor of the car 3 from the stop floor calculation unit 103, and the car 3 stops at the stop position 1a of each floor of the building. When it is confirmed that it has arrived (see FIG. 2), the control process of the air curtain device 20 shown in FIG. 4 is started.

  First, the drive control unit 104 inputs the registration result of the registration unit 101 and the stop floor information of the car 3 from the stop floor calculation unit 103, and the floor registered by the registration unit 101 and the stop floor calculation unit 103 It is determined whether or not the calculated stop floor of the car 3 matches (step (hereinafter referred to as S) 41).

The air curtain device 20 is stopped by outputting a control command for opening the door 9A to the door drive device 14 and outputting a stop command for the drive motor 20C to the air curtain device 20 (S43).

  Thereby, since the air curtain device 20 does not drive the output shaft of the drive motor 20C, the air in the hoistway 2 is not blown into the car 3 from the suction port 20A and the discharge port 20B. And if the control process of S43 is performed, the control panel 10 will complete | finish the control process of the air curtain apparatus 20. FIG.

  According to the first embodiment of the present invention configured as described above, when the drive control unit 104 operates the air curtain device 20 in S42, the air in the hoistway 2 flows from the discharge port 20B to the floor surface of the car 3. Therefore, an air wall is generated between the space in the car 3 and the space in the landing 1A. Therefore, even if the doors 9A and 9B are opened, the air on the platform 3A is prevented from entering the platform 3 from the entrance / exit of the platform 3 by the air wall, so the air in the platform 3 and the interior of the platform 1A It is possible to suppress mixing of air.

  In particular, for example, when the elevator 1 is installed outdoors or the top floor of the building is on the roof, in the summer or winter season, the room temperature in the car 3 and the room temperature in the landing 1A Although the temperature difference occurs, when the car 3 stops on the floor facing the outside of the building, the air in the car 3 and the air in the landing 1A are mixed by the air wall generated by the air curtain device 20 Therefore, it is possible to avoid a sudden change in the room temperature in the car 3.

  Further, for example, when the elevator 1 is installed in a department store, the car 3 stops on a floor where the smell of the landing 1A is likely to be relatively strong, such as a floor of a food department or a cosmetic department. In this case, the air walls generated by the air curtain device 20 suppress the mixing of the air in the car 3 and the air in the landing 1A, so that the smell on the landing 1A side is filled into the car 3. Can be prevented. As described above, the first embodiment of the present invention can mitigate the influence of the odor on the landing 1A side while suppressing the decrease in comfort associated with the change in the room temperature in the car 3, so the car 3 The inside environment can be maintained well.
