Description

  The present invention relates to an elevator car provided with a wind regulation cover that suppresses turbulence of airflow around the car during movement.

  Conventionally, in order to suppress the turbulence of the airflow around the car at the time of movement, there has been proposed an elevator provided with wind regulation covers at the upper and lower parts of the car room. The shape of the air conditioning cover is a semi-dome shape that is less susceptible to air resistance. Thereby, the wind sound produced by the turbulence of the airflow is suppressed, and the noise in the car room is suppressed (for example, see Patent Document 1).

JP-A-5-789

  However, if the inside of the air conditioning cover is a sealed space, a device that requires ventilation (for example, an outdoor unit of an air conditioner) cannot be disposed in the air conditioning cover. In this case, since the equipment must be installed outside the wind regulation cover, the disturbance of the airflow around the car increases due to the equipment outside the wind regulation cover, and the noise in the car room increases. On the other hand, in order to install the device in the air conditioning cover, it is also possible to provide an opening for ventilation in the air conditioning cover, but even in this case, the disturbance of the airflow around the cage increases due to the ventilation opening, Noise in the car room will increase.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain an elevator car that can more reliably suppress noise in the car room.

  An elevator car according to the present invention includes a car room, an air conditioning cover that covers at least one of an upper part and a lower part of the car room, and an open layer separated from the car room by partitioning a space in the air conditioning cover, an open layer, A partition body is provided in the wind regulation cover and a sealing layer interposed between the cabs. The inside of the open layer is open to the outside of the open layer through an opening provided in the wind regulation cover while avoiding the sealing layer.

  In the elevator car according to the present invention, the open layer provided with the opening exists at a position away from the cab, and the sealing layer is interposed between the open layer and the cab, so that the opening is opened through the opening. Ventilation within the layer can be performed. Thereby, even if it is a case where a car mounting apparatus is arrange | positioned in an open layer, the prevention of malfunctions, such as insufficient ventilation and the temperature rise in an open layer, can be aimed at. Therefore, it is possible to avoid that the car-mounted device is disposed outside the wind regulation cover, and it is possible to suppress the turbulence of the airflow caused by the car-mounted device. Further, since the sealing layer is interposed between the open layer and the cab, it is possible to make it difficult for wind noise from the open layer, which is likely to cause turbulence of the airflow, to be transmitted to the cab by the sealing layer. Furthermore, an open layer can be kept away from a cab by interposing a sealing layer. For this reason, it is possible to more reliably suppress noise in the car room.

Embodiment 1 FIG.
1 is a side view showing an elevator car according to Embodiment 1 of the present invention. FIG. 2 is a front view showing the car of FIG. In the figure, a car 2 is suspended in a hoistway 1 by a plurality of suspension bodies 3. For example, a rope or a belt is used as the suspension body 3. The car 2 is disposed between a pair of car guide rails (not shown) installed in the hoistway 1. The car 2 is moved up and down in the hoistway 1 while being guided by each car guide rail by the driving force of a hoisting machine (not shown) installed in the hoistway 1.

  The car 2 includes a car frame 4, a car room 5 supported by the car frame 4, an upper air conditioning cover 6 that covers the upper part of the car room 5, a lower air conditioning cover 7 that covers the lower part of the car room 5, and an upper air conditioning cover. 6 has an upper partition plate (partition body) 8 disposed in the interior 6 and a lower partition plate (partition body) 9 disposed in the lower wind regulation cover 7.

  The car frame 4 includes a lower frame 10 on which the car room 5 is placed, an upper frame 11 which is disposed above the car room 5 and to which each suspension body 3 is connected, and ends of the lower frame 10 and the upper frame 11. And a pair of vertical frames 12 fixed to the section. The car room 5 is disposed between the vertical frames 12. The car frame 4 is suspended by the respective suspension bodies 3.

  The position of the lower end portion of each vertical frame 12 is lower than the position of the lower frame 10. Each of the upper and lower ends of each vertical frame 12 is provided with a guide device 13 having a roller that rolls in contact with the car guide rail.

  A car entrance 14 is provided in front of the car room 5. The car doorway 14 is opened and closed by a pair of car doors 15. In this example, a horizontal ceiling plate 16 is provided at the upper part of the car room 5, and a horizontal floor board 17 is provided at the lower part of the car room 5.

  The upper wind regulation cover 6 covers the upper frame 11 and the ceiling board 16 together, and the lower wind regulation cover 7 covers the lower frame 10 and the floor board 17 together. Each shape of the upper conditioned cover 6 and the lower conditioned cover 7 is a shape that increases continuously as the horizontal cross-sectional area approaches the cab 5. Thereby, the whole shape of the car 2 becomes a streamline, and the turbulence of the airflow generated around the car 2 when the car 2 moves is suppressed. In this example, each of the upper conditioned cover 6 and the lower conditioned cover 7 is a semi-dome-shaped cover main body 18 and a vertical plate fixed to the cover main body 18 and arranged along the moving direction of the car 2. Part 19.

  The upper partition plate 8 is horizontally attached to the inner surface of the upper wind-control cover 6 and the upper frame 11. The space in the upper windbreak cover 6 is partitioned by the upper partition plate 8. Thus, an open layer 20 that is distant from the cab 5 and a sealing layer 21 that is interposed between the open layer 20 and the cab 5 are provided in the upper windbreak cover 6. That is, an open layer 20 and a sealing layer 21 that are two spaces partitioned by the upper partition plate 8 are provided in the upper windbreak cover 6.

  Each suspension body 3 is passed through only the open layer 20 among the open layer 20 and the sealing layer 21. In addition, in the open layer 20, as shown in FIG. 1, a car-mounted device (for example, an outdoor unit of an air conditioner) 22 is arranged avoiding each suspension body 3. The car-mounted device 22 is placed on the upper partition plate 8.

  A plurality of through holes (openings) 23 through which the respective suspension bodies 3 are passed, and ventilation openings (openings) 24 that are located closer to the cab 5 than the positions of the respective through holes 23 are provided in the upper windbreak cover 6. And are provided. The through holes 23 and the ventilation openings 24 are provided only in the open layer 20, avoiding the sealing layer 21. The inside of the open layer 20 is opened to the outside of the open layer 20 through each through hole 23 and the ventilation port 24.

  Here, FIG. 3 is a longitudinal cross-sectional view showing the open layer 20 in the upper windbreak cover 6 of FIG. When the car 2 rises, the outside air flows into the open layer 20 through the through holes 23, and the air in the open layer 20 flows out of the car 2 through the ventilation port 24. Accordingly, an air flow is generated in the open layer 20, and ventilation in the open layer 20 is enabled.

  As shown in FIG. 1, no opening is provided in the upper wind regulation cover 6, the upper partition plate 8, and the ceiling plate 16 that surround the sealing layer 21. That is, the hermetic layer 21 is a sealed space surrounded by the upper wind regulation cover 6, the upper partition plate 8, and the ceiling plate 16. Therefore, the entry and exit of air into the sealing layer 21 is suppressed.

  The lower partition plate 9 is horizontally attached to the inner surface of the lower airflow cover 7. The space in the lower wind conditioned cover 7 is partitioned by a lower partition plate 9. As a result, an open layer 25 that is distant from the cab 5 and a sealing layer 26 that is interposed between the open layer 25 and the cab 5 are provided in the lower conditioned cover 7.

  The lower air conditioning cover 7 is provided with a ventilation opening (opening) 27 that opens the open layer 25. The ventilation port 27 is provided only in the open layer 25, avoiding the sealing layer 26. Thereby, ventilation in the open layer 25 becomes possible, and the entrance and exit of air with respect to the sealing layer 26 is suppressed.

  In such an elevator car 2, the open layers 20 and 25 provided with the through holes 23 and the ventilation ports 24 and 27 exist at a position away from the car room 5, and the sealed layers 21 and 26 that are sealed spaces are provided. Since it is interposed between the open layers 20 and 25 and the cab 5, the open layers 20 and 25 can be ventilated through the vents 24 and 27 and the like. Thereby, even if it is a case where the car mounting apparatus 22 is arrange | positioned in the open layers 20 and 25, problems, such as insufficient ventilation and the temperature rise in an open layer, can be aimed at. Therefore, it is possible to prevent the car-mounted device 22 from being disposed outside the upper wind conditioned cover 6 and the lower wind conditioned cover 7, and the turbulence of the air flow by the car mounted device 22 can be suppressed. In addition, since the sealed layers 21 and 26 that are sealed air layers are interposed between the open layers 20 and 25 and the cab 5, wind noise from the open layers 20 and 25 that are likely to cause turbulence of the airflow is generated. The airtight layers 21 and 26 can make it difficult to convey the cab 5. Furthermore, the open layers 20 and 25 can be kept away from the cab 5 by interposing the sealing layers 21 and 26. For this reason, noise in the cab 5 can be more reliably suppressed.

  In addition, each suspension body 3 that suspends the car frame 4 is connected to the car frame 4 through only the open layer 20 out of the open layer 20 and the seal layer 21, so that the sealed state of the seal layer 21 is ensured. The car frame 4 can be covered with the upper wind-conditioning cover 6 as it is. As a result, the suspension body 3 can be connected to the car frame 4 while the noise suppression effect in the car room 5 is secured.

  Moreover, since the open layer 20 and the sealing layer 21 are partitioned by the upper partition plate 8 and the open layer 25 and the seal layer 26 are partitioned by the lower partition plate 9, each of the upper partition plate 8 and the lower partition plate 9 is provided. By adjusting the position, the sizes of the open layers 20 and 25 can be freely adjusted. Thereby, even the large-sized car-mounted device 22 can be easily arranged in the open layers 20 and 25.

  A sound absorbing material having a sound absorbing effect (for example, glass wool or the like) may be disposed in the sealing layers 21 and 26. In this way, the sound from the open layers 20 and 25 can be absorbed by the sound absorbing material in the sealing layers 21 and 26. Therefore, the wind noise from the open layers 20 and 25 into the car room 5 is further difficult to be transmitted, and the noise in the car room 5 can be further suppressed.

  In the above example, the open layer 20 and the sealing layer 21 are provided in the upper conditioned cover 6, and the open layer 25 and the sealed layer 26 are provided in the lower conditioned cover 7. It may be provided only in either the upper conditioned cover 6 or the lower conditioned cover 7.

  Further, in the above example, the upper conditioned cover 6 is provided in the upper part of the cab 5 and the lower conditioned cover 7 is provided in the lower part of the cab 5, but either the upper conditioned cover 6 or the lower conditioned cover 7 is used. Only the car room 5 may be provided.
