Switch 28 is an example of a detector for detecting when sterilizer 25 is in the retracted position. FIG. 3 shows a preferred example in which the lower surface of the sterilizer 25 is flush with the ceiling surface of the car 1 when the sterilizer 25 is placed in the retracted position.

FIG. 4 is a diagram for explaining the functions of the control device 6. As shown in FIG. The control device 6 includes a registration section 41 , an operation control section 42 , a condition determination section 43 and a sterilization control section 44 . The operation of the elevator system will be described in detail below with reference to FIGS. 5 and 6 as well. FIG. 5 is a flow chart showing an operation example of the elevator device according to Embodiment 1. FIG.

The control device 6 controls normal operation (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 . Upon receiving a registration request from the operation panel 9, the registration unit 41 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 . Upon receiving a registration request from the operation panel 20, the registration unit 41 registers a car call.

In normal operation, the operation control unit 42 causes the car 1 to sequentially respond 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 car 1 is stopped at the landing 8 , the operation control unit 42 controls the motor 19 to open the door 18 . The operation control unit 42 controls movement of the car 1 and opening/closing of the door 18 .

While normal operation is being performed, the condition determination unit 43 determines whether or not a specific start condition is satisfied (S102). A 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 radiating ultraviolet rays from the sterilization device 25 .

A start condition is preset. For example, when the car 1 is unmanned and no call is registered for a certain period of time, the start condition is met. The start condition may be satisfied at a specific date and time. The start requirement may be satisfied at a specific time.

If the start condition is not met (No in S102), the sterilizer 25 is placed at the retracted position. When the sterilizer 25 is placed in the retracted position, the underside of the sterilizer 25 forms part of the roof surface of the car 1 . No ultraviolet light is emitted from the sterilization device 25 when the sterilization device 25 is placed in the retracted position.

When the start condition is satisfied (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 let out the flat cable 26 . As a result, the sterilizer 25 descends (S104). When the lowering of the sterilizer 25 begins, the switch 28 no longer detects that the sterilizer 25 is in the retracted position.

When the sterilization device 25 starts to descend in S104, the sterilization control unit 44 emits ultraviolet rays from the sterilization device 25 (S105). FIG. 6 is a diagram for explaining the sterilization operation. FIG. 6 corresponds to the BB section of FIG. FIG. 6 shows a state in which ultraviolet rays are emitted from the sterilization device 25. As shown in FIG.

By starting the descent of the sterilizing device 25 in S104, the sterilizing device 25 is arranged between the ceiling surface and the floor surface of the car 17, that is, the car 1. The sterilization control unit 44 emits ultraviolet rays from the sterilization device 25 when the sterilization device 25 is arranged between the ceiling surface and the floor surface.

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 a transparent member. As a result, ultraviolet rays can be emitted in all directions from the sterilization device 25 . As another example, five surfaces other than the top surface of the housing 30 may be formed of a transparent member. As a result, the floor 11, the walls 12 to 14, and the sleeve wall 15 can be irradiated with the ultraviolet rays from the sterilization device 25 at the same time. As another example, four surfaces other than the top and bottom surfaces of the housing 30 may be formed of a transparent member. As a result, the ultraviolet rays from the sterilization device 25 can be simultaneously applied to the walls 12 to 14 and the sleeve wall 15, which are easily touched by passengers. The sterilization control unit 44 radiates ultraviolet rays from the sterilization device 25 while lowering the sterilization device 25 .

While the ultraviolet sterilization is being performed, the condition determination unit 43 determines whether or not a specific stop condition is satisfied (S106). A central condition is set in advance. For example, if a call is registered while the sterilization operation is being performed, the cancellation condition is met (Yes in S106).

If the cancellation condition is not met (No in S106), it is determined whether or not the sterilizer 25 has reached the reverse position (S107). The sterilizer 25 reaches the inverted position before contacting the floor 11 . When the sterilization device 25 reaches the reversing position, the sterilization control section 44 controls the winding device 27 to wind the flat cable 26 . As a result, the sterilizer 25 is lifted (S108). The sterilization control unit 44 radiates ultraviolet rays from the sterilization device 25 while raising the sterilization device 25 .

Even 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 cancellation condition is met (Yes in S109).

If the cancellation condition is not met (No in S109), it is determined whether or not the sterilizer 25 is placed at the storage position (S110). When the switch 28 detects that the sterilizer 25 is in the retracted position, a determination of Yes is made in S110. If determined as Yes in S110, the sterilization control unit 44 ends the sterilization operation (S111). At S111, the sterilization device 25 stops emitting ultraviolet rays. After that, normal operation is resumed.

On the other hand, if determined as Yes in S106, the sterilization control unit 44 stops the sterilization operation (S112). Also when it is determined as Yes in S109, the sterilization control unit 44 stops the sterilization operation (S112). At S112, the sterilization device 25 no longer emits ultraviolet rays. Also, the sterilization control unit 44 raises the sterilization device 25 to place the sterilization device 25 at the storage position.

When the sterilization operation is stopped in S112, the operation control unit 42 causes the car 1 to respond to the registered call (S113). That is, the operation control unit 42 causes the car 1 to stop at the landing 8 . When the car 1 stops at the hall 8, it is determined whether or not the sterilizer 25 is in the retracted position (S114). The operation control unit 42 does not open the door 18 unless the switch 28 detects that the sterilizer 25 is located at the retracted position (No in S114). When the switch 28 detects that the sterilizer 25 is in the retracted position (Yes in S114), the operation control unit 42 opens the door 18 (S115).

If the door 18 does not open even though the car 1 is stopped at the landing 8, the passengers at the landing 8 may misunderstand that there is a failure. Therefore, 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 be opened after the sterilization operation is finished.

In the example shown in this embodiment, the sterilizer 25 moves up and down in the car room 17 . Since the position of the light source, that is, the lamp 29 within the cage 1 is changed, the object to be sterilized can be irradiated with ultraviolet rays from various directions. Since ultraviolet rays can be applied to more surfaces, the inside of the car 1 can be effectively sterilized.

In this embodiment, a preferred example in which ultraviolet rays are emitted from the sterilization device 25 while the sterilization device 25 is moving up and down has been described. If a relatively long time can be secured for the sterilization operation, the sterilization control section 44 may radiate ultraviolet rays from the sterilization device 25 after stopping the sterilization device 25 . In such a case, the sterilization control section 44 may stop the sterilization device 25 at a plurality of heights in the car room 17 .

In this embodiment, a preferred example has been described in which the lower surface of the sterilizing device 25 forms a part of the ceiling surface of the car 1 when the sterilizing device 25 is arranged at the storage position. In such a case, considering the design of the ceiling surface, the lower surface of the sterilizer 25 may be formed of a design member. The design member is arranged below the lamp 29 . The design member may be a member that does not transmit light.

FIG. 7 is a diagram showing another example of the sterilization device 25. As shown in FIG. FIG. 7 is a diagram corresponding to FIG. In the example shown in FIG. 7 , the sterilization device 25 further includes a reflector 31 in addition to the lamp 29 and housing 30 . The housing 30 includes a design member 30 a arranged below the lamp 29 .

The design member 30a does not transmit light. Therefore, in the example shown in FIG. 7, the light from the lamp 29 is guided below the design member 30a by the reflector 31. As shown in FIG. This makes it possible to irradiate the area of the floor directly below the sterilizer 25 with the ultraviolet rays. As an example, the reflector 31 is positioned as shown in FIG. 7 when the sterilizer 25 is closest to the floor 11 . While the walls 12 to 14 and the sleeve wall 15 are being sterilized by the sterilizing device 25, the reflector 31 is placed in a position where it does not block the radiation of ultraviolet rays, as indicated by the two-dot chain line in FIG. .

This Embodiment demonstrated the example provided with the one sterilization apparatus 25 in an elevator apparatus. As in the example shown in FIG. 2, when the car 1 is provided with the operation panel 20 and the sub-operation panel 21, the sterilization device 25 for mainly sterilizing the operation panel 20 and the sub-operation panel 21 are mainly sterilized. Another sterilization device 25 may be provided for.

FIG. 8 is a diagram showing an example of hardware resources of the control device 6. As shown in FIG. The control device 6 includes a processing circuit 50 including a processor 51 and a memory 52 as hardware resources. A plurality of processors 51 may be included in the processing circuitry 50 .
