Definitions
- the present invention relates to a passenger transport system which is designed as an escalator or moving walk and has a disinfection device.
- Passenger transport systems are used to transport people within buildings or structures. Germs in the form of viruses, bacteria, spores and/or microbes can accumulate on the surfaces of a passenger transport system.
- a disinfection device can be provided in the passenger transport system in order to be able to avoid their transmission to users of the passenger transport system.
- the disinfection device can be set up to disinfect movable surfaces of the passenger transport system, for example by killing and/or removing germs located there.
- a disinfection device uses sources such as light-emitting diodes (FEDs), which emit germicidal electromagnetic radiation.
- FEDs light-emitting diodes
- UVC wet diodes can be used for this purpose, which emit high-energy ultraviolet radiation, which is also referred to as UVC radiation and typically has a wavelength range of 100-300 nm, usually 180-280 nm.
- CN 106 608 587 A discloses a passenger transport system with a disinfection device and sensors integrated in the handrail.
- a control unit of The passenger transport system is connected to the sensor and the disinfection device via a communication module.
- the sensor detects that a user grabs one of the handrails
- the people transport system and the disinfection device are put into operation in the sense of an automatic start/stop.
- the escalator will slow down, if necessary, to a standstill.
- a disadvantage of the proposed solution is that if the disinfection device fails, the user has to grasp a handrail covered with germs in order to start or keep the escalator in operation.
- JP 2006 193319 A also discloses a disinfection device with UVC light-emitting diodes, with hot air also being blown onto the handrail by means of a hot-air blower.
- the hot air is intended to dry the surface of the handrail in order to further reduce the chances of the germs surviving.
- the object of the present invention is therefore to ensure that the disinfection device reliably disinfects movable surfaces on the passenger transport system and comes up with a design that causes little installation and maintenance effort and therefore low costs.
- a disinfection device for disinfecting a movable surface of a passenger transport system with the features of claim 1.
- the disinfection device has a housing with an interior and at least one radiation source arranged in the interior, the radiation source being able to emit germicidal electromagnetic radiation. So that the germicidal, electromagnetic radiation can penetrate from the interior and disinfect a movable surface of a passenger transport system, a side wall of the housing facing the radiation source is designed to be radiation-permeable.
- the disinfection device also has a device arranged in the interior of the housing and at least one radiation measurement sensor.
- the device is arranged between the at least one radiation source and the radiation-permeable side wall and enables a portion of the radiation emitted by the at least one radiation source to be adequately detected by the radiation measurement sensor.
- the radiation emitted by the radiation source can be used to check the functionality of the disinfection device.
- the radiation intensity can also be recorded and readjusted if necessary, since the radiation sources such as UVC fluorescent tubes or UVC light-emitting diodes are subject to an aging process and their radiation capacity decreases over time if the energy supply remains the same.
- a further advantage of this arrangement is that the at least one radiation source, the device and the at least one radiation measurement sensor are hermetically enclosed in the interior of the housing and are therefore protected from environmental influences such as moisture and dirt. Furthermore, this proposed "all in one solution” leads to minimal installation effort, since the radiation measurement sensor is already ideally arranged and aligned to the radiation sources in the interior of the housing when using the device and is not a suitable mounting location for the disinfection device when it is installed Radiation measurement sensor must be found within the people transport system. Replacing or exchanging an arrangement that is damaged or no longer functioning in any other way is also simplified in this way.
- a plurality of radiation sources can be distributed over a large area on a circuit board.
- This circuit board can be arranged parallel to the radiation-transmissive side wall and opposite it, in the interior of the housing.
- the circuit board can also form a side wall of the housing arranged opposite the radiation-transmissive side wall, with the radiation sources arranged on the circuit board being arranged in the interior.
- a device is also arranged in the interior, which enables a proportion of the radiation emitted by the at least one radiation source to be adequately detected by the radiation measuring sensor.
- the device can be configured differently.
- the device can have a projection which is arranged on the circuit board and which extends towards the radiation-transmissive side wall.
- the at least one radiation measurement sensor is arranged on this projection in such a way that it is in an elevated position relative to the radiation sources, as a result of which a portion of the radiation emitted by these radiation sources can be directly detected by the radiation measurement sensor.
- the device may also include other parts such as cable connections, wireless transmitters, fasteners connecting the protrusion to the radiation measurement sensor, fasteners connecting the protrusion to the housing or circuit board described above, and the like.
- At least one radiation measurement sensor is arranged on the circuit board.
- the device comprises a reflective zone arranged in the area of the radiation-transmissive side wall.
- the reflective zone is arranged in relation to the radiation measurement sensor and to the radiation sources in such a way that a proportion of the radiation emitted by the at least one radiation source can be deflected onto the radiation measurement sensor.
- the circuit board has at least one opening.
- a radiation measuring sensor is also arranged in the interior in a plane which is at a distance from the circuit board and is at a greater distance from the radiation-transmissive side wall than the circuit board.
- a reflective zone is also arranged in the region of the radiation-permeable side wall in such a way that a portion of the radiation emitted by the at least one radiation source can be deflected through the aperture onto the radiation measurement sensor.
- a reflecting zone that is larger in terms of its area can be detected by the radiation measurement sensor due to the changed beam path.
- the configurations of the device described above can be implemented individually in the interior, which means that only one of these configuration variants is present in the interior. However, it is also possible for two of these design variants to be implemented in the same interior space. If, for example, a radiation measurement sensor is arranged on a projection and is irradiated directly and another radiation measurement sensor is arranged on the circuit board and is indirectly irradiated by radiation deflected in the reflecting zone, the sensor signals of these two radiation measurement sensors can be compared with one another and evaluated. A similar decrease in both sensor signals would be weaker, for example indicate emitting sources of radiation.
- the radiation measurement sensor arranged on the projection continuously detects the same amount of radiation, but the radiation measurement sensor arranged on the circuit board detects increasing radiation, this can indicate that the radiation-permeable side wall is increasingly covered with reflective dirt. Further evaluations are also possible here, such as the complete failure of a radiation measurement sensor and the like.
- the reflective zone can also be configured differently.
- the device has a sticker that adheres to the surface of the radiation-transmissive side wall that is directed towards the interior and has a radiation-reflecting coating as the reflective zone.
- the device can comprise a coating or treatment which is applied to the surface of the radiation-transmissive side wall which is directed towards the interior and which has a radiation-reflecting property.
- the reflective zone can be designed to be partially reflective, so that a portion of the emitted radiation reflects and the rest of the emitted radiation penetrates the device in the reflective zone.
- the reflective zone can only partially span the radiation-transmissive side wall.
- the areas that are not spanned allow the electromagnetic, germicidal radiation emitted by the radiation sources to penetrate through the radiation-permeable side wall almost unhindered.
- the device can have a converging lens which is arranged on the circuit board and rises against the radiation-transmissive side wall.
- the radiation from the radiation source reflected from the inner walls of the housing is bundled in a focal point or a focal line of the converging lens and directed to a radiation measuring sensor.
- the radiation-transmissive side wall can be designed as a cover part that can be detached from the rest of the housing. As a result, the interior of the housing is freely accessible when the cover part is removed.
- the disinfection device can have two mirror-symmetrical screens, which are attached to two opposite sides of the housing in such a way that the radiation-permeable side wall between the side walls towering aperture is arranged.
- Each screen comprises a sheet metal part formed by folds, one end of the formed sheet metal part being fixed to the housing and the other end of the formed sheet metal part extending towards the sheet metal part arranged opposite on the housing.
- the inner sides of the two shaped sheet metal parts facing each other and the radiation-transmissive side wall are designed as mirror surfaces.
- the two screens with the housing form a kind of tunnel through which the movable surface to be disinfected, for example that of the handrail described above, is passed.
- the disinfection device described above is designed in particular for use in passenger transport systems that are designed as escalators or moving walks.
- a passenger transport system has at least one balustrade, which includes at least one circumferential handrail.
- This handrail has the movable surface to be disinfected, since it runs along with the conveyor belt and is gripped by the hand of the user of the passenger transport system while driving.
- the people transport system has at least one disinfection device for each encircling handrail.
- the balustrade comprises a balustrade base, in which a returning run of the handrail is concealed from the users of the people-transport system, it is advantageous for the disinfection device to be installed in the balustrade base of the balustrade.
- this preserves the aesthetics of the balustrade and, on the other hand, protects the user from the germicidal, protected against electromagnetic radiation, which cannot penetrate the usually opaque cladding sheets of the balustrade base.
- the passenger transport system In order that users of the passenger transport system can be transported, it also includes a revolving conveyor belt, the leading strand of which can be walked on by users and the return strand of which is arranged inside the passenger transport system and is hidden from the users.
- the conveyor belt is also a movable surface that can be disinfected if necessary.
- the passenger transport system can also have at least one disinfection device for the conveyor belt. In this case, however, no screens may be necessary.

- the disinfection device 41 Since the returning strand of the handrail 17 is also guided in the balustrade base 13 , it is advantageous to arrange the disinfection device 41 in the balustrade base 13 and to guide the returning strand there through or over this disinfection device 41 . It can thereby be ensured that no harmful electromagnetic radiation can reach the users of the passenger transport system 1 under any circumstances.
- a disinfection device 42 which is intended to disinfect the conveyor belt 9 . Their arrangement is preferably provided below the return section of the conveyor belt 9, so that the surfaces that come into contact with users can be sufficiently irradiated.

- FIGS. 3 to 5 all show the same disinfection device 41 already shown in FIGS. 1 and 2 and provided for the handrail 17, or at least parts thereof. For this reason, FIGS. 3 to 5 are described together below. So that more details can be shown in FIG. 3, the handrail 17 of the passenger transport system 1 is represented symbolically by means of a double arrow.

- the disinfection device 41 shown in FIGS. 3 to 5 comprises a housing 51 whose side walls 53, 55, 57, 59 enclose an interior space 61.
- the side walls 53, 55, 57, 59 are designed as flat side walls 53, 55, 57, 59, so that the housing 51 has the shape of a flat, rectangular box.
- At least one of these side walls 53, 55, 57, 59 is designed as a radiation-transmissive side wall 57.
- a plurality of radiation sources 43 are arranged in the interior space 61 .
- the radiation sources 43 are shown as UVC light-emitting diodes which can emit electromagnetic radiation with a wavelength of 100 to 300 nm, preferably 220 to 280 nm.
- the UVC light-emitting diodes or radiation sources 43 are distributed over a flat area on a flat circuit board 63, on which other electronic components 65 required for operating and controlling the radiation sources 43 can also be installed. Due to their design, the radiation sources 43 have a light cone 45 , emitting germicidal electromagnetic radiation in the area of their light cone 45 .
- the luminous cones 45 are aligned with the radiation-transmissive side wall 57 . In other words, the radiation-permeable side wall 57 faces the radiation sources 43 or the circuit board 63 provided with the radiation sources 43 is arranged opposite the radiation-transmissive side wall 57 .
- the radiation-transmissive side wall 57 can be designed as a cover that can be detached from the rest of the housing 51 .

By detecting a proportion of the radiation source 43 emitted radiation, the functionality of the disinfection device 41 can be checked on the one hand.
- the radiation intensity can also be recorded and readjusted if necessary, since radiation sources such as UVC fluorescent tubes or UVC light-emitting diodes are subject to an aging process and their radiation capacity decreases over time if the energy supply remains the same.
- the advantage of this arrangement is that the at least one radiation source 43, the device 71 and the radiation measurement sensor 81 are hermetically enclosed in the interior 61 of the housing 51 and are therefore protected from environmental influences such as moisture and dirt.
- the device 71 has a projection 73 which is arranged on the circuit board 63 and extends towards the side wall 57 which is transparent to radiation.
- On this ledge 73 at least one radiation measurement sensor 81 is arranged in such a way that the radiation measurement sensor 81 is in an elevated position relative to the radiation sources 43.
- the projection 73 is a base arranged on the circuit board 63, which rises above the UVC light-emitting diodes or radiation sources 43 and holds the radiation measurement sensor 81 in at least one of the light cones 45 emanating from them. Due to the elevated position of the radiation measurement sensor 81, a portion of the radiation emitted by the radiation sources 43 can thus be directly detected by the radiation measurement sensor 81.
- the circuit board 63 has at least one opening 75.
- a radiation measurement sensor 81 is arranged in a plane of the interior space 61 which is at a distance from the circuit board 63 and which is at a greater distance from the radiation-transmissive side wall 57 than the circuit board 63 .
- a reflective zone 77 belonging to the device 71 is arranged in the area of the radiation-permeable side wall 57 in such a way that a portion of the radiation emitted by the at least one radiation source 43 can be deflected through the opening 75 onto the radiation measuring sensor 81 .

- the reflective zone 77 is aligned in such a way that a portion of the radiation from each of the radiation sources 43 arranged in the interior is reflected onto the radiation measurement sensor 81 . If necessary, the spatial conditions of the interior 61 are so small that more than one radiation measurement sensor 81 is required for this and the radiation sources 43 are thereby monitored in groups.
- the device 71 can have a sticker on the surface 79 directed towards the interior 61 of the radiation-transmissive side wall 57 adheres and as a reflective zone 77 has a radiation-reflecting coating.
- a corresponding sticker is a surface element whose front side reflects the radiation and whose back side is designed to be self-adhesive for adhesion to the surface 79 .
- the device 71 comprises a coating or treatment applied to the surface 79 of the radiation-transmissive side wall 57 directed towards the interior space 61, which coating has a radiation-reflecting property.
- the reflective zone 77 it is also possible for the reflective zone 77 to be designed to be partially reflective, so that a portion of the emitted radiation reflects and the remainder of the emitted radiation penetrates the device 71 in the reflective zone 77 . As indicated in FIG. 3, the reflective zone 77 preferably only partially spans the radiation-permeable side wall 57, so that the radiation emitted by the radiation sources 43 can penetrate the radiation-permeable side wall 57 for the most part unhindered.
- the converging lens 83 is arranged on the circuit board 63 and rises against the radiation-permeable side wall 57, electromagnetic radiation from the radiation sources 43 reflected from the inner walls of the housing 51 being bundled at a focal point 85 or in a focal line of the converging lens 83 and directed onto a radiation measurement sensor 81.
- a reflective zone 77 can of course also be present in this embodiment, which is arranged or formed in the region of the radiation-transmissive side wall 57 and reflects a portion of the radiation onto the converging lens 83 .
- the disinfection device 41 can have two mirror-symmetrical screens 91, 93.
- the two screens 91, 93 are fastened to two opposite sides of the housing 51 in such a way that the radiation-transmissive side wall 57 is arranged between the screens 91, 93 projecting laterally.
- Each panel 91, 93 comprises a sheet metal part 94 formed by folds, with one end 97 of the formed sheet metal part 94 at the Housing 51 is fixed and the other end 95 of the shaped sheet metal part 94 extends in each case against the oppositely arranged sheet metal part 94 on the housing 51 . So that the electromagnetic radiation penetrating through the radiation-transmissive side wall 57 and striking the screens 91, 93 can be deflected onto the surface of the handrail 17 to be disinfected with as little scattering loss as possible, the inner sides 99 of the two shaped sheet metal parts 94 facing each other and the radiation-transmissive side wall 57 are mirror surfaces educated. Since the conveyor belt 9 only has surfaces to be disinfected, which can be sufficiently irradiated or disinfected from one radiation direction, no screens 91, 93 are required for the disinfection device 42 indicated in FIGS.
- Figures 1 to 5 show different aspects of the present invention based on a passenger transport system 1 designed as an escalator, which is intended to connect vertically spaced floors El, E2, it is obvious that the disinfection devices 41, 42 described can also be used in the same way for moving walks arranged at an angle or horizontally arranged moving walks can be used.
- the reflective zone is preferably arranged on the inside of the radiation-transmissive side wall and thus between the radiation source and the radiation-transmissive side wall. This protects the reflective zone from damage caused by environmental influences.
- a reflective zone arranged directly on the outside of the radiation-transmissive side wall is a functionally equivalent solution and is therefore included in the scope of protection.
