The car 1 moves up and down in a hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The car 1 and the counterweight 2 are suspended from the hoistway 3 by a rope 4.

[0013] The rope 4 is wound around a hoisting machine 5. The car 1 is driven by the hoisting machine 5. The hoisting machine 5 is controlled by a control device 6. FIG. 1 shows an example in which the hoisting machine 5 and the control device 6 are installed in a machine room 7 above the hoistway 3. The hoisting machine 5 and the control device 6 may also be installed in the hoistway 3. When the hoisting machine 5 is installed in the hoistway 3, the hoisting machine 5 may be installed at the top of the hoistway 3 or in a pit of the hoistway 3.

[0014] Fig. 2 is a cross-sectional view showing an example of the car 1. Fig. 2 shows a cross-section taken along line AA in Fig. 1. The car 1 includes a plurality of panels 10.

For example, when the car 1 moves upward, the ventilation device 14 functions as an intake device, and the ventilation device 15 functions as an exhaust device. That is, the air in the elevator shaft 3 is taken in by the ventilation device 14 into the car room 12. The air in the car room 12 is exhausted to the elevator shaft 3 by the ventilation device 15. When the car 1 moves downward, the ventilation device 14 functions as an exhaust device, and the ventilation device 15 functions as an intake device. That is, the air in the elevator shaft 3 is taken in by the ventilation device 15 into the car room 12. The air in the car room 12 is exhausted to the elevator shaft 3 by the ventilation device 14.

Fig. 7 is a diagram showing a CC cross section of Fig. 2. The ventilation device 15 corresponds to a device in which the blades 16 of the ventilation device 14 are arranged upside down. The ventilation device 15 includes a large number of blades 26 and a cover 27.

[0029] In the example shown in the present embodiment, each of the blades 26 is a rectangular plate member. Each of the blades 26 is provided on the panel 10h.

Wing 26d is preferably parallel to wing 26c. An air passage 28c that leads to the inside of car chamber 12 through opening 11h is formed between wing 26d and wing 26c.

[0034] The same applies to the blades disposed below blade 26d.

[0035] The cover 27 is provided on the panel 10h so as to cover the blades 26 from the sides. That is, the blades 26a to 26d are covered from the sides by the cover 27. By providing the cover 27 on the panel 10h, an air passage 29 that opens upward and downward is formed outside the cage 12 by the cover 27 and the panel 10h. The air passage 29 communicates with the air passages formed between the blades 26 inside the cover 27. That is, the air passage 29 communicates with the air passages 28a to 28c inside the cover 27.

The blade plate 26 is provided between the side plates 31 and 32.

[0038] FIG. 8 is a diagram for explaining the functions of the ventilation devices 14 and 15. FIG. 8 shows an example in which the car 1 moves upward. When the car 1 moves upward, the air in the hoistway 3 enters the inside of the ventilation device 14. Specifically, when the car 1 moves upward, the air in the hoistway 3 enters the air passage 19 from above as shown by the arrow F1. A part of the air that has entered the air passage 19 hits the slats 16 and passes through the air passage between the slats 16 as shown by the arrow F2, and is taken into the inside of the car chamber 12. Another part of the air that has entered the air passage 19 passes through the air passage 19 as shown by the arrow F3. The air that has passed through the air passage 19 is discharged downward from the ventilation device 14. In this way, when the car 1 moves upward, the ventilation device 14 functions as an intake device.

[0039] Furthermore, when the car 1 moves upward, the air in the elevator shaft 3 also enters the inside of the ventilation device 15. Specifically, when the car 1 moves upward, the air in the elevator shaft 3 enters the air passage 29 from above, as indicated by the arrow F4. As described above, the slats 26 of the ventilation device 15 extend obliquely downward from the panel 10h. Therefore, the air that enters the air passage 29 from above passes through the air passage 29 without entering the air passage between the slats 26. That is, the air that enters the ventilation device 15 from above passes through the air passage 29 and is discharged downward from the ventilation device 15, as indicated by the arrow F5.

[0040] Because the slats 26 protrude from the panel 10h, the cross-sectional area of ​​the middle part of the air passage 29 is smaller than the area of ​​the upper opening. For this reason, the speed of the air passing through the air passage 29 (relative speed with respect to the car 1) is greater than the moving speed of the car 1. When the car 1 moves upward, the air pressure in the air passage 29 decreases as the air passes through the air passage 29. As a result, the air inside the car chamber 12 flows into the air passage between the slats 26 as indicated by the arrow F6, and enters the air passage 29. In this way, when the car 1 moves upward, the ventilator 15 functions as an exhaust device.

[0041] When the car 1 moves downward, the air in the elevator shaft 3 enters the inside of the ventilation device 15 from below. Since the slats 26 of the ventilation device 15 extend diagonally downward from the panel 10h, the ventilation device 15 functions as an intake device. Also, when the car 1 moves downward, the air in the elevator shaft 3 enters the inside of the ventilation device 14 from below. Since the slats 16 of the ventilation device 14 extend diagonally upward from the panel 10d, the ventilation device 14 functions as an exhaust device like the ventilation device 15 when the car 1 moves upward.

[0042] In the example shown in this embodiment, when the car 1 moves upward, the ventilation device 15 functions as an exhaust device. When the car 1 moves downward, the ventilation device 14 functions as an exhaust device. Therefore, the air inside the car room 12 can be efficiently exhausted to the elevator shaft 3, and the ventilation performance can be improved.

[0043] As in the example shown in this embodiment, by forming the upper end of the aerator 30 so that it moves away from the panel 10h as it goes upward, it is possible to further improve the exhaust performance when the car 1 moves upward. Similarly, by forming the lower end of the aerator 20 so that it moves away from the panel 10d as it goes downward, it is possible to further improve the exhaust performance when the car 1 moves downward.

[0044] In this embodiment, as shown in Figures 5 and 7, an example has been described in which the blades 16 and 26 are formed from the same material as the material that constitutes the panel 10. As another example, the blade 16 may be formed from a material different from the material that constitutes the panel 10. In such a case, the blade 16 may be fixed to the panel 10 by bolts or the like. The blade 26 may be formed from a material different from the material that constitutes the panel 10. In such a case, the blade 26 may be fixed to the panel 10 by bolts or the like.

[0045] Fig. 9 is a cross-sectional view showing another example of the car 1. Fig. 9 shows the AA cross section of Fig. 1. The example shown in Fig. 9 differs from the example shown in Fig. 2 in that the car 1 is equipped with a plurality of ventilation devices 14 and a plurality of ventilation devices 15. As shown in Fig. 9, the number of ventilation devices 14 equipped in the car 1 is not limited to one. The number of ventilation devices 15 equipped in the car 1 is not limited to one.

[0046] In this embodiment, an example has been described in which car 1 is equipped with both ventilation device 14 and ventilation device 15. Car 1 may be equipped with ventilation device 14, but not necessarily with ventilation device 15. Car 1 may be equipped with ventilation device 15, but not necessarily with ventilation device 14. Even in such cases, a certain degree of effect can be expected. [Explanation of symbols]
