FIG. 2 is a diagram showing the configuration of the elevator spray device in the first embodiment.

As shown in FIG. 2, the cage 6 has four side walls, a ceiling, and a floor. The upper part of each of the four side walls of the cage 6 is a panel. The lower part of each of the four side walls of the cage 6 is a baseboard 11. The baseboard 11 is provided along the outer periphery of the lower part of the side wall of the cage 6. The panel and the baseboard 11 are in contact with each other via a gap.

The spray device 9 comprises a storage section 12, multiple tube sections 13, and multiple spray sections 14.

The storage unit 12 is provided at the top of the basket 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 that the liquid can be pumped out at regular intervals using a timer.

For example, each of the multiple tubular sections 13 is a tube. For example, each of the multiple tubular sections 13 is a resin tube. The multiple tubular sections 13 are provided on the outside of the cage 6. One end of each of the multiple tubular sections 13 is connected to the storage section 12.

For example, each of the multiple spray units 14 is a nozzle. Each of the multiple spray units 14 is provided on the side of the cage 6. Each of the multiple tube units 13 and each of the multiple spray units 14 are provided in correspondence with each other. Each of the multiple spray units 14 is connected to the other end of each of the multiple spray units 14.

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 sections 13. For example, the storage unit 12 switches between spraying and not spraying for each of the multiple tube sections 13.

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.

Each of the multiple spray units 14 sprays the liquid delivered from the multiple tube units 13 onto the floor surface of the cage 6.

In FIG. 2, the ventilation device 8 blows air from the top to the bottom of the car 6. After the air reaches the bottom of the car 6, it is exhausted outside the car 6 through the gap between the panel and the baseboard 11.

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 according to the first embodiment is applied.

As shown in FIG. 3, the spray unit 14 is provided so as to penetrate the baseboard 11. The spray unit 14 is provided on the upper part of the baseboard 11. For example, on the central side of the cage 6, the spray unit 14 is provided on the upper part of the baseboard 11.

According to the embodiment 1 described above, the spray device 9 sprays liquid onto the floor surface of the car 6 from the side portion 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.

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. This can prevent the inside of the cage 6 from becoming an unpleasant space.

The storage unit 12 also pumps out the stored liquid at regular intervals. This allows the liquid to be sprayed before its effectiveness wears off.

In addition, each of the multiple tube sections 13 is provided corresponding to each of the multiple spray sections 14. This allows the liquid to be sprayed reliably.

In addition, multiple tube sections 13 may be provided corresponding to the side sections of the cage 6. The other end of the tube section 13 may be branched and connected to multiple spray sections 14 at the corresponding side section of the cage 6. In this case, the tube section 13 sends liquid to multiple spray sections 14 at the corresponding side section of the cage 6. In this case, the number of tube sections 13 can be reduced.

In addition, the reservoir 12 adjusts the pump pressure to match the length of each of the multiple tube sections 13. This improves the accuracy of liquid spraying.

The storage unit 12 also dispenses liquid when the user is not in the car 6. This allows the liquid to be sprayed without causing discomfort to the user.

The spray unit 14 is also provided on the top of the baseboard 11. This allows the liquid to be sprayed over a greater distance. In particular, when the spray unit 14 is provided on the top of the baseboard 11 at the center of the car 6, the liquid can be sprayed onto the center of the floor of the car 6.

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.

As shown in FIG. 4, the spray unit 14 is provided at the bottom of the baseboard 11. For example, at the four corners of the cage 6, the spray unit 14 is provided at the bottom of the baseboard 11.

According to the first modification of the first embodiment described above, the spray unit 14 is provided at the bottom of the baseboard 11. This allows liquid to be sprayed onto the corners of the floor of the car 6.

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 of the car 6. The spray unit 14 may be provided on the lower part of the baseboard 11 at the four corners of the car 6. In this case, the liquid can be sprayed over the entire floor surface of the car 6.

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 embodiment 1 is applied.

According to the second modification of the first embodiment described above, the spray unit 14 is provided at the bottom of the baseboard 11. This allows liquid to be sprayed onto the corners of the floor of the car 6.

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.

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 the spray area of the corresponding spray unit 14 as its detection area. The detection unit 15 detects a user of the car 6.

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

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

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 users are not detected. Therefore, even if a user is in the car 6, the spray device 9 can spray liquid without causing discomfort to the user.

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