Next, an example of the operation of the control device 8 will be described with reference to FIGS. 4 and 5.
4 and 5 are flow charts for explaining an example of the operation of the control device of the elevator system to which the elevator hall blower according to Embodiment 1 of the present invention is applied.

  For example, a pollen patient wants to go to the clinic from the first floor to the sixth floor. At this time, the pollen patient registers the hall call on the first floor. The control device 8 causes the car 3 to respond to the hall call. When the car 3 arrives on the first floor, the pollen patient gets into the car 3. At this time, in step S1, the control device 8 determines whether or not a destination call on the sixth floor is registered as a destination call on the target floor.

  When the destination call on the sixth floor is not registered in step S1, the control device 8 performs the operation in step S2. In step S2, the control device 8 controls the car 3 according to the situation. Thereafter, the control device 8 ends the operation.

  When the destination call on the sixth floor is registered in step S1, the control device 8 performs the operation in step S3. In step S3, the control device 8 determines whether or not the patient button 3a has been operated within a preset time.

  When the patient button 3a is not operated within the preset time in step S3, the control device 8 performs the operation of step S4. In step S4, the control device 8 makes the car 3 respond to the destination call on the sixth floor. Thereafter, the control device 8 ends the operation.

  When the patient button 3a is operated within a preset time in step S3, the control device 8 performs the operation of step S5. In step S5, the control device 8 shifts the operation mode of the elevator to the pollen operation mode.

  At this time, the control device 8 displays preset information on the hall display devices of all the floors. For example, the control device 8 displays information indicating that the pollen patient is using the elevator on the hall display devices on all floors. For example, the control device 8 causes the hall display devices on all floors to display information that prompts the user of the hall 2 to take a wind.

  Thereafter, the control device 8 performs the operation of step S6. In step S6, the control device 8 determines whether a hall call between the first floor and the sixth floor is registered.

  When the hall call between the first floor and the sixth floor is not registered in step S6, the control device 8 performs the operation of step S7. In step S7, the control device 8 makes the car 3 respond to the destination call on the sixth floor. Thereafter, the control device 8 ends the operation.

  When the hall call between the first floor and the sixth floor is registered in step S6, the control device 8 performs the operation of step S8. In step S8, the control device 8 determines whether or not the car 3 passes through the floor.

  When the car 3 does not pass the floor in step S8, the control device 8 performs the operation in step S9. In step S9, the control device 8 determines whether or not the amount of pollen detected by the pollen detection device 7 is equal to or greater than a preset amount.

  When the amount of pollen detected by the pollen detection device 7 in step S9 is smaller than the preset amount, the control device 8 performs the operation of step S10. In step S10, the control device 8 causes the car 3 to respond to the hall call. Thereafter, the control device 8 performs the operation of step S11. In step S11, the control device 8 makes the car 3 respond to the destination call on the sixth floor. Thereafter, the control device 8 ends the operation.

  If the amount of pollen detected by the pollen detection device 7 in step S9 is greater than or equal to a preset amount, the control device 8 performs the operation of step S12. In step S12, the control device 8 operates the landing fan 5a on the floor so that the amount of pollen on the floor is smaller than a preset amount before reaching the floor. Thereafter, the control device 8 performs the operation of step S8.

  When the car 3 passes the floor in step S8, the control device 8 performs the operation of step S11. Thereafter, the control device 8 ends the operation.

  According to Embodiment 1 demonstrated above, the landing fan 5a generates a wind. The wind flows from the entrance / exit of the hall 2 to the front side of the hall 2. For this reason, pollen can be moved in the direction away from the hall 2. As a result, pollen can be prevented from entering the building via the elevator.

  Moreover, the blowing device 5b is provided in a three-way frame. For this reason, it is possible to prevent pollen from entering the building via the elevator without impairing the appearance of the entrance / exit of the hall 2.

  In addition, you may provide the blowing apparatus 5b in the upper frame of a three-way frame. In this case, pollen can be more reliably prevented from entering the interior of the building via the elevator.

  Moreover, the door 5c exposes the landing fan 5a to the landing 2 side when opened. For this reason, the maintenance work of the landing fan 5a can be easily performed from the landing 2 side.

  The landing blower 5 operates based on the amount of pollen. For this reason, it can prevent appropriately that a pollen enters the inside of a building via an elevator as needed.

  The car blower 6 operates based on the amount of pollen and the traveling state of the car 3. For this reason, it can prevent appropriately that a pollen enters the inside of a building via an elevator as needed.

  Further, the hoistway blower 4 is interlocked with the car blower 6. For this reason, it is possible to prevent pollen from accumulating in the hoistway 1.

  Moreover, the control apparatus 8 determines whether the car 3 is made to respond to a hall call based on the quantity of pollen. For this reason, it is possible to prevent pollen from entering the interior of the building via the elevator while considering the operation efficiency of the elevator.

  Moreover, the control apparatus 8 operates the hall air blower 5 so that the car 3 can respond to the hall call. For this reason, it can prevent that pollen enters the inside of a building via an elevator, maintaining the operation efficiency of an elevator.

  Note that at least one of the wind pressure and the air volume of the landing fan 5 may be controlled based on the time until the car 3 arrives at the floor. In this case, the car can appropriately respond to the registered hall call. As a result, the operation efficiency of the elevator can be maintained.

  Further, in the hall 2, a mark may be attached at a position where the wind of the pair of hall fans 5a hits. Furthermore, the user existing at the position of the mark may be detected by a sensor or the like. In this case, the user should be notified of the position to wait based on the detection result of the sensor. In this case, pollen adhering to a user's clothes etc. can be removed more appropriately.

  In addition, a destination floor button may be provided at the hall 2. At this time, when the destination floor button corresponding to a specific floor is operated, the elevator operation mode may be shifted to the pollen operation mode. Also in this case, pollen can be prevented from entering the building via the elevator.
