DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Embodiment 1 Fig. 1 is a front view showing a main part of an elevator in which an elevator ultraviolet sterilization device according to embodiment 1 is installed. The elevator includes a car 1 where passengers get on and off, a car operating panel 2, an in-car monitor 3, and an in-car lighting device 4.

[0010] The car operation panel 2 is provided on a sleeve wall portion 101 of the car 1. The car operation panel 2 is a part that is touched by a user inside the car 1. In addition, the car operation panel 2 is a sterilization target member that is sterilized by an elevator ultraviolet sterilization device.

[0011] The car operation panel 2 has a plurality of destination floor buttons 201 that are operated by a user in the car 1. When a user in the car 1 operates the destination floor button 201 on the car operation panel 2, the car 1 moves to a destination floor corresponding to the operated destination floor button 201.

[0012] The car interior monitor 3 is provided on the sleeve wall portion 101 of the car 1, above the car operation panel 2. The car interior monitor 3 displays a number indicating the floor on which the car 1 is located and an arrow indicating the direction in which the car 1 is moving. This makes it possible to inform users in the car 1 of information on the floor on which the car 1 is located and information on the direction in which the car 1 is moving.

[0013] The car interior lighting device 4 is provided on a ceiling portion 102 of the car 1. When the car interior lighting device 4 is turned on, the inside of the car 1 is illuminated.

[0014] Fig. 2 is a block diagram showing an elevator ultraviolet sterilization device according to the first embodiment. The elevator ultraviolet sterilization device according to the first embodiment includes an ultraviolet irradiator 5, a user detection device 6, an ultraviolet irradiator switch 7, and a control device 8. The elevator includes an elevator control panel 9 and a maintenance and inspection switch 10. The ultraviolet irradiator 5, the user detection device 6, and the ultraviolet irradiator switch 7 are each electrically connected to the control device 8. The maintenance and inspection switch 10 is electrically connected to the elevator control panel 9.

[0015] The ultraviolet irradiation device 5 emits ultraviolet light. The control device 8 controls the ultraviolet irradiation device 5 to emit ultraviolet light.

[0016] The user detection device 6 detects a user in the car 1. The detection result of the user detection device 6 is input to the control device 8. Based on the detection result of the user detection device 6, the control device 8 determines whether or not a user has been detected by the user detection device 6 in the car 1.

[0017] The ultraviolet irradiation switch 7 is provided in the car 1. The ultraviolet irradiation switch 7 is operated by an operator when the operator performs maintenance and inspection of the elevator ultraviolet sterilization device. When the ultraviolet irradiation switch 7 is operated, an operation signal is generated in the ultraviolet irradiation switch 7.

[0018] The operation signal generated in the ultraviolet irradiation switch 7 includes an ON signal indicating that the ultraviolet irradiation switch 7 is in the ON state, and an OFF signal indicating that the ultraviolet irradiation switch 7 is in the OFF state. When the ultraviolet irradiation switch 7 is in the ON state, an ON signal is generated in the ultraviolet irradiation switch 7, and when the ultraviolet irradiation switch 7 is in the OFF state, an OFF signal is generated in the ultraviolet irradiation switch 7.

[0019] An operation signal of the ultraviolet irradiation switch 7 is input to the control device 8. The control device 8 controls the emission of ultraviolet light from the ultraviolet irradiation device 5 based on the operation signal of the ultraviolet irradiation switch 7. When an ON signal of the ultraviolet irradiation switch 7 is input to the control device 8, the control device 8 causes the ultraviolet irradiation device 5 to emit ultraviolet light. On the other hand, when an OFF signal of the ultraviolet irradiation switch 7 is input to the control device 8, the control device 8 causes the ultraviolet irradiation device 5 to stop emitting ultraviolet light.

[0020] An elevator control panel 9 is electrically connected to the control device 8.

[0021] The elevator control panel 9 is adapted to switch the operation mode of the elevator between a normal operation mode and a maintenance and inspection mode. Furthermore, when the operation mode of the elevator is the normal operation mode, the elevator control panel 9 is adapted to switch the operation mode of the elevator between an automatic operation mode and an automatic pause mode. When the operation mode of the elevator is the automatic operation mode, the car interior lighting device 4 is turned on. When the operation mode of the elevator is the automatic pause mode, the car interior lighting device 4 is turned off.

[0022] When the elevator operation mode is in the automatic operation mode, if the elevator is not used for a preset period of time, for example, 3 minutes, the elevator control panel 9 switches the elevator operation mode from the automatic operation mode to the automatic pause mode.

[0023] When the elevator operation mode is in the automatic pause mode and a user operates the elevator, the elevator control panel 9 switches the elevator operation mode from the automatic pause mode to the automatic operation mode, thereby enabling the user to use the elevator.

[0024] When the operation mode of the elevator is the automatic pause mode, automatic pause mode information indicating that the operation mode of the elevator is the automatic pause mode is input from the elevator control panel 9 to the control device 8.

[0025] The maintenance and inspection switch 10 is operated by an operator. When the operator performs maintenance and inspection of the elevator ultraviolet sterilization device, the operator switches the maintenance and inspection switch 10 from an OFF state to an ON state. When the maintenance and inspection switch 10 is operated, an operation signal is generated in the maintenance and inspection switch 10.

[0026] The operation signal of the maintenance and inspection switch 10 includes an ON signal indicating that the state of the maintenance and inspection switch 10 is the ON state, and an OFF signal indicating that the state of the maintenance and inspection switch 10 is the OFF state. When the state of the maintenance and inspection switch 10 is the ON state, an ON signal is generated in the maintenance and inspection switch 10, and when the state of the maintenance and inspection switch 10 is the OFF state, an OFF signal is generated in the maintenance and inspection switch 10.

[0027] An operation signal of the maintenance and inspection switch 10 is input to the elevator control panel 9. Based on the operation signal of the maintenance and inspection switch 10, the elevator control panel 9 switches the operation mode of the elevator between a normal operation mode and a maintenance and inspection mode.

[0028] When the maintenance / inspection switch 10 is in the on state, the elevator control panel 9 sets the operation mode of the elevator to the maintenance / inspection mode. When the operation mode of the elevator is in the maintenance / inspection mode, users cannot use the elevator.

[0029] When the maintenance and inspection of the elevator ultraviolet sterilization device is completed, the worker switches the maintenance and inspection switch 10 from the on state to the off state. When the maintenance and inspection switch 10 is in the off state, the elevator control panel 9 sets the operation mode of the elevator to the normal operation mode.

[0030] When the elevator operation mode is the normal operation mode, the elevator control panel 9 switches the elevator operation mode between the automatic operation mode and the automatic pause mode depending on whether the elevator is in use by a user. On the other hand, when the elevator operation mode is the maintenance and inspection mode, the elevator control panel 9 sets the elevator operation mode to the maintenance and inspection mode, and does not set the elevator operation mode to the automatic operation mode or the automatic pause mode.

[0031] When the operation mode of the elevator is the maintenance and inspection mode, maintenance operation mode information indicating that the operation mode of the elevator is the maintenance and inspection mode is input from the elevator control panel 9 to the control device 8.

[0032] Fig. 3 is a side view showing a main part of the elevator in Fig. 1. The user detection device 6 is provided on the ceiling part 102 of the car 1. The user detection device 6 detects a user in the car 1 by using infrared rays. Note that the user detection device 6 may be configured to detect a user in the car 1 by measuring the weight of the user in the car 1.

[0033] The ultraviolet irradiating device 5 is provided on a rear wall 103 of the car 1. The rear wall 103 of the car 1 is a wall of the car 1 that faces the door of the car 1 when the door of the car 1 is in the closed position.

[0034] The ultraviolet irradiation device 5 is disposed so as to face the car operation panel 2. The ultraviolet irradiation device 5 irradiates the car operation panel 2 with ultraviolet light 11. The ultraviolet light 11 emitted from the ultraviolet irradiation device 5 hits the entire surface of the car operation panel 2. The area of ​​the surface of the car operation panel 2 that is hit by the ultraviolet light 11 emitted from the ultraviolet irradiation device 5 is set as a sterilization target area 202. The sterilization target area 202 of the car operation panel 2 is the entire area facing the ultraviolet irradiation device 5 on the car operation panel 2.

[0035] The ultraviolet irradiation device 5 is configured to irradiate the entire sterilization target area 202 of the car operation panel 2 with ultraviolet rays 11 at once. The direction in which the ultraviolet rays 11 are emitted from the ultraviolet irradiation device 5 is defined as the ultraviolet irradiation direction. Therefore, the ultraviolet irradiation direction of the ultraviolet irradiation device 5 is the direction facing from the ultraviolet irradiation device 5 to the sterilization target area 202 of the car operation panel 2.

[0036] The ultraviolet irradiation direction of the ultraviolet irradiation device 5 may be rotatable around an axis along a vertical line. By rotating the ultraviolet irradiation direction of the ultraviolet irradiation device 5 around an axis along a vertical line, the portion of the sterilization target area 202 of the car operating panel 2 that is irradiated with the ultraviolet light 11 emitted from the ultraviolet irradiation device 5 moves in the width direction of the car 1. The width direction of the car 1 is the direction that coincides with the frontage direction of the car entrance / exit formed in the car 1. In this case, the amount of ultraviolet light 11 emitted at one time from the ultraviolet irradiation device 5 can be reduced. As a result, the ultraviolet irradiation device 5 can be made more compact.

[0037] Furthermore, the ultraviolet irradiation direction of the ultraviolet irradiation device 5 may be rotatable around an axis extending in the width direction of the car 1. By rotating the ultraviolet irradiation direction of the ultraviolet irradiation device 5 around an axis extending in the width direction of the car 1, the portion of the car operation panel 2 in which the ultraviolet rays 11 emitted from the ultraviolet irradiation device 5 are irradiated moves along a vertical line. In this case, the amount of ultraviolet rays 11 emitted at one time from the ultraviolet irradiation device 5 can be reduced. As a result, the ultraviolet irradiation device 5 can be made smaller in size.

[0038] Fig. 4 is a diagram showing a state in which an ultraviolet irradiation confirmation member 12 is provided on the car 1 in Fig. 3. Fig. 5 is a diagram showing the ultraviolet irradiation confirmation member 12 in Fig. 4 as viewed from the rear wall 103 of the car 1 toward the sleeve wall portion 101. The elevator ultraviolet sterilization device according to the first embodiment is equipped with an ultraviolet irradiation confirmation member 12.

[0039] The ultraviolet irradiation confirmation member 12 is detachably attached to the sleeve wall portion 101 of the car 1. The ultraviolet irradiation confirmation member 12 is attached to the car 1 by a worker when maintenance and inspection of the elevator ultraviolet sterilization device are performed.

[0040] The ultraviolet irradiation confirmation member 12 can be attached to the cage 1 by, for example, a magnet, a suction cup, or a fastening member. Fastening members can be, for example, screws or bolts.

[0041] The ultraviolet ray irradiation confirmation member 12 is made of a material that changes color when the ultraviolet ray 11 is irradiated onto the ultraviolet ray irradiation confirmation member 12. The color change of the ultraviolet ray irradiation confirmation member 12 also includes the emission of light from the ultraviolet ray irradiation confirmation member 12.

[0042] When the ultraviolet irradiation confirmation member 12 is attached to the car 1, the ultraviolet irradiation confirmation member 12 is disposed between the ultraviolet irradiator 5 and the car operating panel 2. Specifically, when the ultraviolet irradiation confirmation member 12 is attached to the car 1, the ultraviolet irradiation confirmation member 12 covers the entire area of ​​the sterilization target area 202 of the car operating panel 2.

[0043] Next, an operation of the elevator ultraviolet sterilization device according to embodiment 1 will be described. Fig. 6 is a flowchart showing the operation of the elevator ultraviolet sterilization device according to embodiment 1. Fig. 6 shows the operation of the elevator ultraviolet sterilization device when the elevator operation mode is the normal operation mode.

[0044] First, in step S101, the controller 8 determines whether or not the operation mode of the elevator is the automatic pause mode based on whether or not automatic pause mode information has been input to the controller 8 from the elevator control panel 9.

[0045] When the control device 8 determines in step S101 that the operation mode of the elevator is the automatic pause mode, a user detection determination step is performed in step S102. In the user detection determination step, the control device 8 determines whether or not a user has been detected in the car 1 by the user detection device 6 based on the detection result of the user detection device 6. In other words, in the user detection determination step, the control device 8 determines whether or not there is anyone in the car 1.

[0046] In step S102, when the control device 8 determines that a user has not been detected by the user detection device 6 in the car 1, an ultraviolet irradiation start step is performed in step S103. In the ultraviolet irradiation start step, the control device 8 starts irradiating the car operation panel 2 with ultraviolet light 11 by the ultraviolet irradiation device 5.

[0047] Thereafter, in step S104, an irradiation time completion determination step is performed. In the irradiation time completion determination step, the control device 8 determines whether or not the irradiation time of the ultraviolet irradiating device 5 with the ultraviolet ray 11 onto the car operating panel 2 has reached a preset time. The irradiation time of the ultraviolet irradiating device 5 with the ultraviolet ray 11 onto the car operating panel 2 is preset in the control device 8. An example of the preset irradiation time of the ultraviolet ray 11 is 10 minutes. Note that the preset irradiation time of the ultraviolet ray 11 is not limited to 10 minutes, and may be any time that allows the car operating panel 2 to be sterilized by irradiation with the ultraviolet ray 11.

[0048] When the control device 8 determines in step S104 that the irradiation time of the ultraviolet ray 11 by the ultraviolet ray irradiation device 5 to the car operation panel 2 has reached a preset time, an ultraviolet ray irradiation termination process is performed in step S105. In the ultraviolet ray irradiation termination process, the control device 8 stops the irradiation of the ultraviolet ray 11 by the ultraviolet ray irradiation device 5 to the car operation panel 2. This ends the operation of the elevator ultraviolet sterilization device.

[0049] In step S101, if the control device 8 determines that the operation mode of the elevator is not the automatic pause mode, the process of step S101 is repeated.

[0050] In step S102, when the control device 8 determines that a user in the car 1 has been detected by the user detection device 6, the process of the operation of the elevator ultraviolet sterilization device returns to the process of step S101.

[0051] In step S104, if the control device 8 determines that the irradiation time of the ultraviolet ray 11 by the ultraviolet ray irradiation device 5 to the car operating panel 2 has not reached the preset time, the process of step S104 is repeated.

[0052] Next, a description will be given of a method for maintaining and inspecting the elevator ultraviolet sterilization device according to embodiment 1. Fig. 7 is a flowchart showing a method for maintaining and inspecting the elevator ultraviolet sterilization device according to embodiment 1.

[0053] First, in step S201, a maintenance and inspection switch-on process is performed. In the maintenance and inspection switch-on process, an operator operates the maintenance and inspection switch 10 to switch the maintenance and inspection switch 10 from an OFF state to an ON state. This causes the elevator control panel 9 to switch the operation mode of the elevator from a normal operation mode to a maintenance and inspection mode, and maintenance operation mode information is input from the elevator control panel 9 to the control device 8.

[0054] Thereafter, in step S202, an ultraviolet irradiation confirmation member attachment process is performed. In the ultraviolet irradiation confirmation member attachment process, the worker attaches the ultraviolet irradiation confirmation member 12 to the car 1. As a result, the sterilization target area 202 of the car operating panel 2 is covered with the ultraviolet irradiation confirmation member 12.

[0055] Thereafter, in step S203, an ultraviolet irradiation start process is performed. In the ultraviolet irradiation start process, an operator operates the ultraviolet irradiation switch 7, and the ultraviolet irradiation device 5 emits ultraviolet rays 11. The ultraviolet rays 11 emitted from the ultraviolet irradiation device 5 hit the ultraviolet irradiation confirmation member 12. A color change occurs in the portion of the ultraviolet irradiation confirmation member 12 on which the ultraviolet rays 11 hit. By visually checking the discolored portion of the ultraviolet irradiation confirmation member 12, the operator can confirm the area of ​​the car operating panel 2 on which the ultraviolet rays 11 are irradiated from the ultraviolet irradiation device 5.

[0056] Thereafter, in step S204, an ultraviolet irradiation terminating step is performed. In the ultraviolet irradiation terminating step, the operator operates the ultraviolet irradiation switch 7 to stop the ultraviolet irradiation device 5 from emitting the ultraviolet rays 11.

[0057] Thereafter, in step S205, an ultraviolet ray irradiation confirmation member detachment process is performed. In the ultraviolet ray irradiation confirmation member detachment process, the worker detaches the ultraviolet ray irradiation confirmation member 12 from the car 1.

[0058] Then, in step S206, a maintenance and inspection switch-off process is performed. In the maintenance and inspection switch-off process, the worker operates the maintenance and inspection switch 10 to switch the maintenance and inspection switch 10 from the on state to the off state. This causes the elevator control panel 9 to switch the operation mode of the elevator from the maintenance and inspection mode to the normal operation mode. This completes the maintenance and inspection of the elevator ultraviolet sterilization device.

[0059] As described above, the elevator ultraviolet sterilization device according to the first embodiment includes the ultraviolet irradiator 5 and the ultraviolet irradiating confirmation member 12. The ultraviolet irradiator 5 is provided on the car 1, and irradiates the car operation panel 2 with ultraviolet rays 11. The ultraviolet irradiating confirmation member 12 is detachably attached to the car 1. The ultraviolet irradiating confirmation member 12 changes color when irradiated with ultraviolet rays 11. When the ultraviolet irradiating confirmation member 12 is attached to the car 1, the ultraviolet irradiating confirmation member 12 is disposed between the ultraviolet irradiator 5 and the car operation panel 2. According to this configuration, by attaching the ultraviolet irradiating confirmation member 12 to the car 1, it can be easily confirmed that the ultraviolet irradiating device 5 irradiates the car operation panel 2 with ultraviolet rays 11.

[0060] Furthermore, when the ultraviolet irradiation confirmation member 12 is attached to the car 1, the ultraviolet irradiation confirmation member 12 covers the sterilization target area 202 of the car operating panel 2 that is hit by the ultraviolet rays 11 emitted from the ultraviolet irradiation device 5. According to this configuration, by attaching the ultraviolet irradiation confirmation member 12 to the car 1, it can be more accurately confirmed that the ultraviolet rays 11 are being irradiated from the ultraviolet irradiation device 5 to the car operating panel 2.

[0061] Moreover, the elevator ultraviolet sterilization device according to the first embodiment is equipped with a control device 8. The control device 8 controls the irradiation of ultraviolet rays 11 by the ultraviolet irradiator 5 to the car operation panel 2. When the operation mode of the elevator is the automatic pause mode, the control device 8 causes the ultraviolet irradiator 5 to irradiate ultraviolet rays 11. With this configuration, the car operation panel 2 can be sterilized when the elevator is not in use.

[0062] Moreover, the elevator ultraviolet sterilization device according to the first embodiment includes a user detection device 6. The user detection device 6 detects a user in the car 1. When no user is detected in the car 1 by the user detection device 6 and the operation mode of the elevator is the automatic pause mode, the control device 8 causes the ultraviolet irradiator 5 to irradiate ultraviolet rays 11. With this configuration, the car operation panel 2 can be sterilized during a time when the elevator is not in use and when there is no user in the car 1.

[0063] In the first embodiment, the car operating panel 2 has been described as an example of a member to be sterilized. However, the member to be sterilized may be, for example, an in-car handrail. In this case, the ultraviolet irradiation device 5 irradiates the in-car handrail with ultraviolet light 11. The in-car handrail is sterilized by irradiating the in-car handrail with ultraviolet light 11. In this case, when the ultraviolet irradiation confirmation member 12 is attached to the car 1, the ultraviolet irradiation confirmation member 12 is disposed between the ultraviolet irradiation device 5 and the in-car handrail. In other words, when the ultraviolet irradiation confirmation member 12 is attached to the car, the ultraviolet irradiation confirmation member 12 covers the area of ​​the surface of the in-car handrail that is hit by the ultraviolet light 11 emitted from the ultraviolet irradiation device 5.

[0064] Also, in the first embodiment, a configuration has been described in which the worker visually checks the color change of the ultraviolet irradiation confirmation member 12 inside the car 1. However, a configuration may also be adopted in which a camera that photographs the ultraviolet irradiation confirmation member 12 and a display device that displays the image photographed by the camera are provided, and the worker visually checks the color change of the ultraviolet irradiation confirmation member 12 using the display device. By disposing the display device outside the car 1, the worker can visually check the color change of the ultraviolet irradiation confirmation member 12 outside the car 1. This makes it possible to prevent ultraviolet rays 11 from being irradiated to the worker. [Explanation of symbols]
