[0014] The ventilation device 8 is provided on the ceiling of the car 6. The spray device 9 is provided in the car 6.

[0015] The control device 10 is provided in the machine room 2. The control device 10 is electrically connected to the hoist 4, the ventilation device 8, and the spray device 9. The control device 10 is provided so as to be able to control the elevator as a whole. The control device 10 determines whether or not a passenger is present in the car 6 by a known method. For example, the known method is a load sensor.

[0016] Next, the configuration of the elevator spray device 9 will be described with reference to FIG. FIG. 2 is a diagram showing the configuration of the elevator spray device in the first embodiment.

[0017] As shown in Fig. 2, the car 6 has four side surfaces, a ceiling, and a floor. The upper part of each of the four side surfaces of the car 6 is a panel. The lower part of each of the four side surfaces of the car 6 is a baseboard 11. The baseboard 11 is provided along the outer periphery of the lower part of the side surfaces of the car 6. The panel and the baseboard 11 are in contact with each other via a gap.

[0018] The spray device 9 includes a storage section 12, a plurality of tubular sections 13, and a plurality of spray sections .

[0019] The storage unit 12 is provided on the upper part of the cage 6. The storage unit 12 stores a liquid. For example, the liquid is a deodorant. For example, the liquid is an antibacterial agent. For example, the liquid is a disinfectant. The storage unit 12 includes a pump. For example, the pump is provided so as to be able to pump the liquid at regular intervals using a timer.

[0020] For example, each of the multiple tubular parts 13 is a tube. For example, each of the multiple tubular parts 13 is a resin tube. The multiple tubular parts 13 are provided on the outside of the cage 6. One end of each of the multiple tubular parts 13 is connected to the storage part 12.

[0021] For example, each of the multiple spray units 14 is a nozzle. Each of the multiple spray units 14 is provided on a side surface of the cage 6. Each of the multiple pipe units 13 and each of the multiple spray units 14 are provided to correspond to each other. Each of the multiple spray units 14 is connected to the other end of each of the multiple spray units 14.

[0022] In the spray device 9, the storage unit 12 receives a signal from the control device 10 (not shown). For example, the storage unit 12 does not operate the pump when it receives information from the control device 10 (not shown) indicating that a user is in the car 6. For example, the storage unit 12 operates the pump when it does not receive information from the control device 10 (not shown) indicating that a user is in the car 6. At this time, the storage unit 12 performs a preset operation. For example, the storage unit 12 adjusts the pump pressure according to the length of each of the multiple tube parts 13. For example, the storage unit 12 switches between spraying and not spraying for each of the multiple tube parts 13.

[0023] Each of the multiple tube sections 13 passes the liquid delivered from the storage section 12. Each of the multiple tube sections 13 delivers the liquid to each of the multiple spray sections 14.

[0024] Each of the multiple spray sections 14 sprays the liquid delivered from the multiple pipe sections 13 onto the floor surface of the car 6.

[0025] 2, the ventilation device 8 blows air from the top to the bottom of the car 6. After reaching the bottom of the car 6, the air is discharged to the outside of the car 6 through a gap between the panel and the baseboard 11.

[0026] Next, the elevator spray unit 14 will be described in detail with reference to FIG. FIG. 3 is a detailed cross-sectional view of an elevator car to which the elevator spray device in the first embodiment is applied.

[0027] 3, the spray unit 14 is provided so as to penetrate the baseboard 11. The spray unit 14 is provided on an upper portion of the baseboard 11. For example, on the central side of the cage 6, the spray unit 14 is provided on an upper portion of the baseboard 11.

[0028] According to the above-described first embodiment, the spray device 9 sprays the liquid onto the floor surface of the car 6 from the side surface of the car 6 near the floor surface of the car 6. Therefore, the liquid can be sprayed onto the floor surface of the car 6.

[0029] In addition, the air discharged from the ventilation device 8 is exhausted to the outside of the cage 6 through the gap between the panel and the baseboard 11. For this reason, dust tends to accumulate on the floor of the cage 6. Also, dust on the shoes of users tends to accumulate on the floor of the cage 6. The spray device 9 can spray a deodorizer on the floor of the cage 6 where dust tends to accumulate. The spray device 9 can reduce the odor inside the cage 6. For this reason, it is possible to prevent the inside of the cage 6 from becoming an unpleasant space.

[0030] Furthermore, the liquid stored in the reservoir 12 is pumped out at regular intervals, so that spraying can be performed before the effect of the liquid to be sprayed wears off.

[0031] Further, each of the plurality of tubular portions 13 is provided corresponding to each of the plurality of spray portions 14. Therefore, the liquid can be sprayed reliably.

[0032] Note that a plurality of tubular sections 13 may be provided corresponding to the side surface of the cage 6. The other end of the tubular section 13 may be branched and connected to a plurality of spray sections 14 at the corresponding side surface of the cage 6. In this case, the tubular section 13 sends liquid to a plurality of spray sections 14 at the corresponding side surface of the cage 6. In this case, the number of tubular sections 13 can be reduced.

[0033] Furthermore, the reservoir 12 adjusts the pump pressure in accordance with the length of each of the multiple tubular portions 13. This can improve the accuracy of liquid spray.

[0034] Moreover, the reservoir 12 delivers the liquid when the user is not in the car 6. Therefore, the liquid can be sprayed without causing discomfort to the user.

[0035] In addition, the spray unit 14 is provided on the upper part of the baseboard 11. Therefore, the liquid can be sprayed over a longer distance. In particular, when the spray unit 14 is provided on the upper part of the baseboard 11 on the central side of the car 6, the liquid can be sprayed on the central part of the floor surface of the car 6.

[0036] Next, a first modified example of the spray device 9 will be described with reference to FIG. FIG. 4 is a detailed cross-sectional view of an elevator car to which a first modified example of the elevator spray device in the first embodiment is applied.

[0037] 4, the spray unit 14 is provided below the baseboard 11. For example, the spray unit 14 is provided below the baseboard 11 on each of the four corners of the cage 6.

[0038] According to the first modification of the first embodiment described above, the spray unit 14 is provided below the baseboard 11. Therefore, the liquid can be sprayed onto the corners of the floor surface of the car 6.

[0039] Note that the first embodiment and the first modified example of the first embodiment may be applied at the same time. Specifically, the spray unit 14 may be provided on the upper part of the baseboard 11 at the center side of the car 6. The spray unit 14 may be provided on the lower part of the baseboard 11 at the four corner sides of the car 6. In this case, the liquid can be sprayed onto the entire floor surface part of the car 6.

[0040] Next, a second modified example of the spray device 9 will be described with reference to FIG. FIG. 5 is a detailed cross-sectional view of an elevator car to which a second modified example of the elevator spray device in the first embodiment is applied.

[0041] As shown in FIG. 5 , the spray portion 14 penetrates the baseboard 11 so as to descend toward the inside of the car 6 .

[0042] According to the second modification of the first embodiment described above, the spray unit 14 is provided below the baseboard 11. Therefore, the liquid can be sprayed onto the corners of the floor surface of the car 6.

[0043] Next, a third modified example of the spray device 9 will be described with reference to FIG. FIG. 6 is a diagram showing the configuration of a spray device for an elevator to which a third modified example of the spray device for an elevator in the first embodiment is applied.

[0044] In the third modified example, the spray device 9 includes a detection unit 15. The detection unit 15 is provided so as to be able to communicate with the storage unit 12. For example, the detection unit 15 is an infrared sensor. The detection unit 15 is provided corresponding to the spray unit 14. The detection unit 15 has a spray area of ​​the corresponding spray unit 14 as its detection area. The detection unit 15 detects a user of the car 6.

[0045] The storage unit 12 sends liquid to the spray unit 14 corresponding to the detection unit 15 that has not detected a user in its own detection area among the multiple detection units 15. Each of the multiple spray units 14 sprays the liquid sent from the storage unit 12 onto the floor surface of the car 6.

[0046] According to the third modification of the first embodiment described above, the storage unit 12 sends liquid to the spray unit 14 corresponding to the detection unit 15 that has not detected a user. Therefore, even if a user is present in the car 6, the liquid can be sprayed in an area where no user is detected.

[0047] In particular, in elevators installed in commercial facilities, there are few times when a user is not in the car 6. The spray device 9 can spray liquid only in areas where a user is not detected. Therefore, even if a user is in the car 6, the spray device 9 can spray liquid without making the user feel uncomfortable.

[0048] In addition, in elevators that do not have a machine room 2 and in which the hoist 4 and control device 10 are provided at the top or bottom of the elevator shaft 1, the spray device 9 of embodiment 1, first modified example, second modified example, and third modified example may be applied.
