[0009] Hereinafter, a detailed description will be given with reference to the drawings. Duplicate descriptions will be appropriately simplified or omitted. In each drawing, the same reference numerals indicate the same or corresponding parts.

[0010] Embodiment 1 FIG. 1 is a diagram showing an example of an elevator apparatus in a first embodiment. The elevator apparatus includes a car 1 and a counterweight 2. The car 1 moves up and down in a hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The hoistway 3 is a space extending vertically in a building. The car 1 and the counterweight 2 are suspended in the hoistway 3 by a rope 4. FIG. 1 shows an example of an elevator apparatus using a 1:1 roping system.

[0011] The rope 4 is wound around a hoist 5. The car 1 is driven by the hoist 5. A control device 6 controls the hoist 5. That is, the movement of the car 1 is controlled by the control device 6. The control device 6 also controls devices provided in the car 1.

[0012] 1 shows an example in which the hoisting machine 5 and the control device 6 are provided in a machine room 7 above the hoistway 3. The hoisting machine 5 and the control device 6 may be provided in the hoistway 3. The hoisting machine 5 may be provided at the top of the hoistway 3 or in a pit of the hoistway 3.

[0013] An operation panel 9 and a display 10 are provided at each landing 8 where the car 1 stops. In the example shown in FIG. 1 , the operation panel 9 has an up button and a down button. The operation panel 9 may also have destination buttons. The display 10 is an example of an alarm that notifies passengers at the landing 8 of information. A speaker may be provided at the landing 8 as an alarm. Both the display 10 and a speaker may be provided at the landing 8.

[0014] Fig. 2 is a diagram showing a cross section taken along line AA in Fig. 1. Fig. 3 is a diagram showing a cross section taken along line BB in Fig. 2. The car 1 includes a floor 11, walls 12 to 14, a sleeve wall 15, and a ceiling 16. The floor 11, walls 12 to 14, sleeve wall 15, and ceiling 16 form a car chamber 17 for passengers to ride in.

[0015] The upper surface of the floor 11 forms the floor surface of the car 1. The wall 12 is a wall located on the far side when viewed from the entrance / exit of the car 1. The wall 13 is a wall located on the left side when viewed from the entrance / exit of the car 1. The wall 14 is a wall located on the right side when viewed from the entrance / exit of the car 1. The sleeve wall 15 is a wall adjacent to the entrance / exit of the car 1. The lower surface of the ceiling 16 forms the ceiling surface of the car 1.

[0016] The car 1 is equipped with a door 18, a motor 19, an operation panel 20, a sub-operation panel 21, and a lighting device 22. The door 18 opens and closes the entrance to the car 1. The door 18 is driven by the motor 19. The operation panel 20 is equipped with a plurality of buttons for passengers to operate. The buttons include a destination button, an open button, and a close button. The operation panel 20 is provided on the sleeve wall 15. The sub-operation panel 21 is equipped with a plurality of buttons for passengers to operate. The buttons include a destination button, an open button, and a close button. The sub-operation panel 21 is provided on the wall 14. The lighting device 22 is provided on the ceiling 16.

[0017] The cage 1 also includes a sterilizer 25, a flat cable 26, a winding device 27, and a switch 28.

[0018] The sterilizer 25 is a device for sterilizing the inside of the cage 1. The sterilizer 25 can emit ultraviolet light for sterilization. For example, the sterilizer 25 includes a lamp 29 and a housing 30. The housing 30 supports the lamp 29. The lamp 29 emits ultraviolet light.

[0019] The flat cable 26 supplies power to the sterilizer 25. The sterilizer 25 is suspended by the flat cable 26. The flat cable 26 is an example of a suspension means for suspending the sterilizer 25. The flat cable 26 may include a reinforcing member according to the weight of the sterilizer 25. The cage 1 may be provided with a suspension means separate from the flat cable 26.

[0020] The winding device 27 is an example of a drive device for moving the sterilizer 25 up and down. The winding device 27 moves the sterilizer 25 upward by winding up the flat cable 26. The winding device 27 moves the sterilizer 25 downward by unwinding the flat cable 26. In this way, the sterilizer 25 moves up and down between the ceiling surface and the floor surface of the car room 17, i.e., the car 1.

[0021] The sterilizer 25 is placed in the storage position while passengers are on board the car 1. Fig. 3 shows the state in which the sterilizer 25 is placed in the storage position. The switch 28 is an example of a detector for detecting that the sterilizer 25 is placed in the storage position. Fig. 3 shows a preferred example in which the bottom surface of the sterilizer 25 is flush with the ceiling surface of the car 1 when the sterilizer 25 is placed in the storage position.

[0022] Fig. 4 is a diagram for explaining the function of the control device 6. The control device 6 includes a registration unit 41, an operation control unit 42, a condition determination unit 43, and a sterilization control unit 44. The operation of the elevator device will be described in detail below with reference to Figs. 5 and 6. Fig. 5 is a flowchart showing an example of the operation of the elevator device in the first embodiment.

[0023] In the control device 6, normal operation is controlled (S101). For example, when the upper button of the operation panel 9 is pressed, a call registration request is transmitted from the operation panel 9 to the control device 6. When the registration unit 41 receives the registration request from the operation panel 9, it registers a hall call. Also, when the destination button on the operation panel 20 is pressed, a call registration request is transmitted from the operation panel 20 to the control device 6. When the registration unit 41 receives the registration request from the operation panel 20, it registers a car call.

[0024] In normal operation, the operation control unit 42 causes the car 1 to respond sequentially to registered calls. For example, the operation control unit 42 controls the hoist 5 to stop the car 1 at the landing 8. When the operation control unit 42 stops the car 1 at the landing 8, it controls the motor 19 to open the door 18. The operation control unit 42 controls the movement of the car 1 and the opening and closing of the door 18.

[0025] During normal operation, the condition determination unit 43 determines whether a specific start condition is satisfied (S102). The start condition is a condition for starting a sterilization operation. The sterilization operation is an operation for sterilizing the inside of the car 1 by emitting ultraviolet rays from the sterilization device 25.

[0026] The start condition is set in advance. For example, the start condition is met when car 1 is unoccupied and no calls are registered for a certain period of time. The start condition may be met at a specific date and time. The start requirement may be met at a specific time.

[0027] If the start condition is not satisfied (No in S102), the sterilizer 25 is placed in the storage position. When the sterilizer 25 is placed in the storage position, the lower surface of the sterilizer 25 forms part of the ceiling surface of the car 1. When the sterilizer 25 is placed in the storage position, no ultraviolet light is emitted from the sterilizer 25.

[0028] When the start condition is met (Yes in S102), the sterilization control unit 44 starts the sterilization operation (S103). First, the sterilization control unit 44 controls the winding device 27 to unwind the flat cable 26. This causes the sterilizer 25 to descend (S104). When the descent of the sterilizer 25 begins, the switch 28 no longer detects that the sterilizer 25 is in the storage position.

[0029] When the sterilization control unit 44 starts to lower the sterilization device 25 in S104, it causes the sterilization device 25 to emit ultraviolet light (S105). Figure 6 is a diagram for explaining the sterilization operation. Figure 6 corresponds to the cross section BB in Figure 2. Figure 6 shows a state in which ultraviolet light is being emitted from the sterilization device 25.

[0030] As the descent of the sterilizer 25 starts in S104, the sterilizer 25 is disposed in the car chamber 17, i.e., between the ceiling surface and the floor surface of the car 1. The sterilization control unit 44 causes the sterilizer 25 to emit ultraviolet rays when the sterilizer 25 is disposed between the ceiling surface and the floor surface.

[0031] If the housing 30 of the sterilizer 25 is box-shaped, it is preferable that the six sides of the housing 30 are made of transparent materials. This allows the sterilizer 25 to emit ultraviolet light in all directions. As another example, the other five sides of the housing 30, excluding the top surface, may be made of transparent materials. This allows the ultraviolet light from the sterilizer 25 to be simultaneously applied to the floor 11, the walls 12-14, and the sleeve wall 15. As another example, the other four sides of the housing 30, excluding the top and bottom surfaces, may be made of transparent materials. This allows the ultraviolet light from the sterilizer 25 to be simultaneously applied to the walls 12-14 and the sleeve wall 15 that passengers are likely to touch. The sterilization control unit 44 causes the sterilizer 25 to emit ultraviolet light while lowering the sterilizer 25.

[0032] While sterilization by ultraviolet light is being performed, the condition determination unit 43 determines whether a specific stop condition is met (S106). The central condition is set in advance. For example, if a call is registered while the sterilization operation is being performed, the stop condition is met (Yes in S106).

[0033] If the stop condition is not met (No in S106), it is determined whether the sterilizer 25 has reached the reversal position (S107). The sterilizer 25 reaches the reversal position before contacting the floor 11. When the sterilizer 25 reaches the reversal position, the sterilization control unit 44 controls the winding device 27 to wind up the flat cable 26. This causes the sterilizer 25 to rise (S108). While raising the sterilizer 25, the sterilization control unit 44 causes the sterilizer 25 to emit ultraviolet light.

[0034] While the sterilization control unit 44 is raising the sterilization device 25, the condition determination unit 43 determines whether or not a specific stop condition is satisfied (S109). For example, if a call is registered while the sterilization operation is being performed, the stop condition is satisfied (Yes in S109).

[0035] If the cancellation condition is not met (No in S109), it is determined whether or not the sterilization device 25 has been placed in the storage position (S110). If the switch 28 detects that the sterilization device 25 has been placed in the storage position, the determination in S110 is Yes. If the determination in S110 is Yes, the sterilization control unit 44 ends the sterilization operation (S111). In S111, ultraviolet light is no longer emitted from the sterilization device 25. Thereafter, normal operation is resumed.

[0036] On the other hand, if the determination in S106 is Yes, the sterilization control unit 44 stops the sterilization operation (S112). If the determination in S109 is Yes, the sterilization control unit 44 also stops the sterilization operation (S112). In S112, ultraviolet light is no longer emitted from the sterilization device 25. In addition, the sterilization control unit 44 raises the sterilization device 25 to place it in the storage position.

[0037] When the sterilization operation is stopped in S112, the operation control unit 42 makes the car 1 respond to the registered call (S113). That is, the operation control unit 42 makes the car 1 stop at the landing 8. When the car 1 stops at the landing 8, it is determined whether or not the sterilization device 25 is placed in the storage position (S114). If the switch 28 does not detect that the sterilization device 25 is placed in the storage position (No in S114), the operation control unit 42 does not open the door 18. If the switch 28 detects that the sterilization device 25 is placed in the storage position (Yes in S114), the operation control unit 42 opens the door 18 (S115).

[0038] If the door 18 does not open even though the car 1 is stopped at the landing 8, passengers at the landing 8 may mistakenly think that a malfunction has occurred. For this reason, while the determination in S114 is No, the operation control unit 42 may display a message on the display 10 to the effect that the door 18 will open after the sterilization operation is completed.

[0039] In the example shown in this embodiment, the sterilizer 25 moves up and down in the cage chamber 17. Since the position of the light source, i.e., the lamp 29, changes within the cage 1, ultraviolet light can be applied to the objects to be sterilized from various directions. Since ultraviolet light can be applied to a larger number of surfaces, the inside of the cage 1 can be sterilized effectively.

[0040] In this embodiment, a preferred example has been described in which ultraviolet rays are emitted from the sterilizer 25 while the sterilizer 25 is moving up and down. If a relatively long time can be secured for the sterilization operation, the sterilization control unit 44 may radiate ultraviolet rays from the sterilizer 25 after stopping the sterilizer 25. In such a case, the sterilization control unit 44 may stop the sterilizer 25 at multiple heights in the cage 17.

[0041] In this embodiment, a preferred example has been described in which the underside of the sterilizer 25 forms part of the ceiling surface of the car 1 when the sterilizer 25 is placed in the storage position. In this case, the underside of the sterilizer 25 may be formed of a design member, taking into consideration the design of the ceiling surface. The design member is placed below the lamp 29. The design member may be a material that does not transmit light.

[0042] Fig. 7 is a diagram showing another example of sterilization device 25. Fig. 7 is a diagram corresponding to Fig. 6. In the example shown in Fig. 7, sterilization device 25 further includes a reflector 31 in addition to lamp 29 and housing 30. Housing 30 includes a design member 30a arranged below lamp 29.

[0043] Design element 30a does not transmit light. Therefore, in the example shown in Fig. 7, light from lamp 29 is guided below design element 30a by reflector 31. This allows ultraviolet light to be directed to the area of ​​the floor surface directly below sterilizer 25. As an example, reflector 31 is positioned as shown in Fig. 7 when sterilizer 25 is closest to floor 11. While sterilizer 25 sterilizes walls 12-14 and sleeve wall 15, reflector 31 is positioned at a position that does not block the emission of ultraviolet light, as shown by the two-dot chain line in Fig. 7.

[0044] In the present embodiment, an example has been described in which the elevator apparatus is equipped with one sterilization device 25. When the car 1 is equipped with the operation panel 20 and the sub-operation panel 21 as in the example shown in Fig. 2, a sterilization device 25 for mainly sterilizing the operation panel 20 and another sterilization device 25 for mainly sterilizing the sub-operation panel 21 may be provided.

[0045] 8 is a diagram showing an example of hardware resources of the control device 6. The control device 6 includes, as hardware resources, a processing circuit 50 including a processor 51 and a memory 52. ​​The processing circuit 50 may include a plurality of processors 51. The processing circuit 50 may include a plurality of memories 52.

[0046] In this embodiment, the units denoted by the reference numerals 41 to 44 indicate functions possessed by the control device 6. The functions of the units denoted by the reference numerals 41 to 44 can be realized by software written as a program, firmware, or a combination of software and firmware. The program is stored in the memory 52. ​​The control device 6 realizes the functions of the units denoted by the reference numerals 41 to 44 by executing the program stored in the memory 52 by the processor 51. A semiconductor memory or the like can be adopted as the memory 52.

[0047] Fig. 9 is a diagram showing another example of hardware resources of the control device 6. In the example shown in Fig. 9, the control device 6 includes a processing circuit 50 including a processor 51, a memory 52, and dedicated hardware 53. Fig. 9 shows an example in which some of the functions of the control device 6 are realized by the dedicated hardware 53. All of the functions of the control device 6 may be realized by the dedicated hardware 53. As the dedicated hardware 53, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination of these can be adopted.
