Definitions
- Disinfection device for a control panel of an input device
- the invention relates to a disinfection device for a control panel of an input device such as a keyboard of a card terminal, with an ultraviolet-emitting diode as an ultraviolet radiation source for generating disinfecting radiation.
- Radiation is understood here to be a range of the electromagnetic spectrum that is invisible to the human eye and not particle radiation.
- the corona pandemic has shown how important it is to break chains of infection to save human lives. Even if there was often talk of a catastrophe in the context of Covidl9, every expert knows that Covidl9 is a relatively harmless pathogen and the emergence of a real problem germ is only a matter of time. For example, Covidl9 has a lethality rate of around 0.5 to 1%, but still causes massive economic damage.
- the disinfection and cleaning of control panels on input devices of, for example, the said card terminals and/or ATMs therefore represents a relevant problem from a hygienic point of view. Wiping with a special alcohol-based cleaning solution at more or less short intervals is currently recommended. However, in normal supermarket checkout operations, this is only possible at longer intervals. Cleaning and disinfection after each payment process is not possible due to time constraints. This means that after an infected person operates the keyboard, all other customers who operate the terminal until the next cleaning can become infected.
- Infection can also be prevented by paying completely contactless. While this works very well at card terminals at points of sale in terms of the process, and a PIN entry or the like is required much less frequently or not at all, such a method has not been possible at ATMs to date. This is i.a. This is due to the fact that all contactless payment methods have potential security deficiencies, which are based on the fundamentally unshielded communication of the cards via radio. Because of these security issues, contactless payment is not accepted by many customers.
- the invention is therefore based on the object of overcoming the disadvantages described and of enabling safe use of an input device by a user.
- the disinfection device has at least one, i.e. one or more, ultraviolet-emitting diodes (UV LEDs) as ultraviolet radiation sources (UV radiation sources) for generating disinfecting radiation with a wavelength, preferably a peak wavelength, of less than 280 nm on.
- UV LEDs ultraviolet-emitting diodes
- the (peak) wavelength of the emitted radiation is preferably also more than 250 nm, preferably 265 nm ⁇ 5 nm, 265 nm ⁇ 1 nm, or 265 nm. Radiation in this wavelength range is also referred to as UVC radiation. Colloquially, such radiation is also often referred to as “UV light” or “UVC light”.
- the invention thus uses a different approach to realizing the inactivation of germs, ie microorganisms such as bacteria, viruses, protozoa or mold, than is the case when wiping: instead of the germs.
- germs ie microorganisms such as bacteria, viruses, protozoa or mold
- the deoxyribonucleic acid (DNA or DNA) of the germs is damaged with the proposed disinfection device by targeted, short and high-intensity UVC radiation in such a way that they can no longer multiply. They are thus inactivated and no longer infectious. Due to the principle of action, this applies to both bacteria and viruses.
- the optimal wavelength here is 265 nm, as it has been found that damage to the pathogen DNA is most efficient in this range and disinfection can therefore be carried out with a particularly low radiation output.
- Ozone is not only an irritant gas, but also absorbs UV radiation in the UVC range itself, and would thus have a reducing effect on the disinfection effect.
- the disinfection device also has a fastening device for fastening the disinfection device to the input device.
- the fastening device and the at least one UV LED are arranged in such a way that when the disinfection device is fastened to the input device as intended, at least a large part of the disinfection radiation generated is emitted onto the control panel of the input device.
- a large part is as large a part as possible of the total disinfection radiation generated by the UV LED(s), preferably more than 50%.
- most of the disinfecting radiation is emitted onto the parts of the control panel that come into mechanical contact with the user when the input device is used as intended, for example onto a touch-sensitive surface and/or at least one button.
- the fastening device thus serves to specify a desired spatial relationship, i. H. Position and orientation of the at least one UV LED relative to the control panel of the input device by permanently attaching the disinfection device to the respective input device.
- the disinfection device can also be adapted with a correspondingly adapted fastening device to input devices that have already been designed or are already on the market, for example card terminals, and can therefore also be designed as a retrofit kit and sold separately from the input device.
- a conventional visual protection device of an input device of a card terminal or an ATM input device without disinfection device can be replaced by the disinfection device described below with a fastening device in the form of the conventional visual protection device.
- the fastening device can accordingly be integrated with the privacy protection device introduced below, thus for example also being attached to the input device as an integrated, in particular one-piece component.
- the at least one UV LED can also be designed to be integrated with a fastening device and/or visual protection device. In this way, protection against infection can be improved quickly for large parts of the population with particularly little effort.
- the disinfection device can also have a control device assigned to the one or more UV LED(s).
- this control device can be designed in such a way that the disinfection device only requires a power supply and the control, i.e. activation and deactivation, of the UV LED(s) is taken over by the control device. This is then preferably done independently of the input device, so that it does not have to be changed even when retrofitting with the disinfection device (apart from providing the power supply), and in particular a control software or firmware does not have to be reprogrammed.
- the control device can be designed in such a way that, in addition to the power supply, there is also a control interface to an external control device, which then controls the control.
- a "fluence”, ie an "area irradiation intensity x time" of at least 400 J/m 2 , i.e. 40 mJ/cm 2 , on a control panel is sufficient to increase the number of exciters by at least 4 logarithmic levels, i.e. 99.99%. to lower.
- the target fluence of the disinfection device in the control device device or control device can be set as a parameter and thus the device can also be adapted to different types of germs.
- the irradiation fluence can also be increased by using UV LEDs with different outputs or by increasing the number of UV LEDs, so that the disinfection time for a given target fluence can be further reduced. Disinfection after each operation can ensure that the next user (practically) no longer has any infectious pathogens on the control panel, thus breaking the chain of infection extremely effectively.
- the control panel has a touch-sensitive surface, in particular a touch-sensitive screen, and/or has at least one button, in particular a keypad with at least one button, preferably at least 12 buttons.
- the keypad can be or include a numeric keypad with two or six additional keys, ie have 12 or 16 keys.
- the keys are usually arranged in a rectangular and approximately square control panel, which facilitates effective illumination by one or more UV radiation sources and thus disinfection.
- the disinfection of control panels with touch-sensitive surfaces or keys is particularly advantageous since such control panels are widespread in input devices in public spaces.
- an optical element which is designed to direct the majority of the generated disinfection radiation, preferably a major part of the generated disinfection radiation, or the entire generated disinfection radiation onto the control panel, in particular onto the parts of the Control panel, which come into mechanical contact with the user when the input device is used as intended.
- a majority can be understood here as a proportion of more than 50 or more than 60%, a predominant majority as a proportion of more than 80 or more than 90%, and the total generated disinfection radiation as a proportion of at least 98%, at least 99%, or 100%.
- the optical element can be a lens element and/or a reflector element and/or a diaphragm element ment to be or include.
- the screen element can be designed to be integrated with the fastening device and/or the privacy protection device introduced below and/or the at least one UV LED and/or other components of the disinfection device, in particular a sensor device and/or control device, thus for example also as an integrated one , In particular one-piece component are attached to the input device.
- the advantage resulting from the optical element is that the disinfecting radiation can be emitted exclusively in the direction of the control panel to be disinfected, and exposure of the user can thus be prevented or at least drastically reduced. In this way, improved security against pathogens is combined with optimized user protection.
- the fastening device is part of a visual protection device or comprises or forms a visual protection device.
- the visual protection device is designed to shield user input on the control panel from third parties when the input device is used as intended. This is generally desirable and customary, especially at cashless sales outlets or at ATMs. Since such visual protection devices naturally protrude from a main plane of extension of the control panel, precisely to prevent a lateral view of the control panel, the at least one UV radiation source can also be arranged on the visual protection device and/or the fastening device outside the main plane of extension at a distance from the control panel.
- the at least one UV radiation source can irradiate the control panel particularly effectively, since the further away the UV radiation source is from the control panel, the closer the beam angle is to the right angle.
- a relatively large control panel can thus be efficiently irradiated and disinfected even with a single UV radiation source.
- an angle of incidence of 90° is particularly suitable for killing or inactivating pathogens and germs.
- the lens element can be manufactured with or from UVC-transparent material such as quartz glass, sapphire glass, UVC-transparent polymers such as “UV-Top 200” or silicon dioxide elements manufactured using the sol-gel process connection device as a retrofit kit for input devices without visual tik (or with to be replaced conventional privacy screen)
- the fastening device can be designed in the form of privacy protection and thus be or include the privacy protection device.
- the visual protection device thus advantageously serves at the same time as radiation shielding of an environment
- the fastening device and/or the visual protection device has or is a cooling element, in particular a passive cooling element.
- the cooling element is
- the fastening device or the sight protection device is preferably made with or from a material with good thermal conductivity, such as aluminum.
- a material with good thermal conductivity such as aluminum.
- one or more lateral flanks and/or an upper cover of the sight protection device or fastening device can have such cooling elements
- the at least one UV LED is a plurality of UV LEDs, ie the disinfection device has a plurality of UV LEDs which are arranged in different orientations. This ensures that the control panel when used as intended, i.e. when the disinfecting radiation is emitted at the input front
- the control panel of the input device from at least two, preferably three different directions is irradiated with the disinfection radiation.
- This has the advantage that a control panel with raised elements, ie elements protruding perpendicularly to the main plane of extension of the control panel, such as Tas
- 35 th also corresponding side flanks, for example the side surfaces of the keys, are irradiated by the disinfecting radiation and thus disinfected will.
- control panel includes a card slot for a debit and/or credit card and/or other card and the UV radiation source is designed to irradiate a surface of the control panel adjacent to the card slot.
- the UV radiation source is designed to irradiate a surface of the control panel adjacent to the card slot.
- the surface of the control panel adjacent to the card slot is concave, it is correspondingly advantageous to attach at least one UV radiation source to two opposite sides, in order to be able to completely irradiate the concave surface of the control panel with the disinfectant radiation and keep it sterile.
- the disinfection device has a sensor device which is designed to detect an intensity of the disinfection radiation. Accordingly, the sensor device then includes a UV sensor. In particular, the sensor device can also be designed to emit an alarm signal if the intensity is lower than a predetermined minimum value.
- the sensor device can be arranged on or in the control panel. Attaching it to or in the control panel has the advantage that the intensity of the disinfection radiation is recorded directly on the relevant surface, the control panel. Alternatively, the sensor device can also be attached in or on the attachment device and/or the visual protection device.
- the disinfection device can remain a self-contained structural unit even without the input device and yet, for example after a suitable standardization of the detected intensity of the disinfection radiation, still has the described advantage of detecting an aging effect or falling below the specified minimum value the intensity can be detected by the sensor device.
- the disinfection device has a control interface for controlling, i.e. activating and deactivating, the UV radiation source.
- This control interface also includes the control channel mentioned above.
- the disinfection radiation can thus be carried out as required at a predetermined time, for example after a card has been removed from the card slot or after a personal identification number (PIN) has been successfully entered. There is therefore sufficient time for disinfection before the next operation is required.
- PIN personal identification number
- the disinfection device has a switching device for controlling, i.e. activating and deactivating, the UV radiation source, preferably with a movement detection unit and/or a time recording unit.
- a switching device for controlling, i.e. activating and deactivating, the UV radiation source preferably with a movement detection unit and/or a time recording unit.
- control device with a motion detection unit can be designed to activate the UV LED after a movement in a predetermined area, for example the area of the control panel, has been detected by the motion detection unit. en.
- the control device can also be designed to only activate the UV LED when no movement is currently being detected in order to protect the user from the disinfecting radiation.
- the control device can be designed to activate the UV LED (for each disinfection process) for a specified time, for example at least 1s or at least 2s or at least 5s or at least 10s or at least 20s and/or for example a maximum of 60s or a maximum 40s or at most 30s or at most 20s or at most 10s or at most 5s.
- the control device can also be designed to interrupt the disinfection process if movement is detected in the specified area while the UV LED is activated and/or only then to begin the disinfection process, i.e. only then to activate the UV LED for the specified time , if a further specified time has elapsed after the end of the detected movement.
- the movement detection unit and/or the time detection unit thus serve to ensure the safety and protection of users from the disinfection radiation, since they can be used to prevent the user's skin and tissue from being damaged by the disinfection radiation.
- entering a PIN as a movement can be detected by the operator detection device and after a predetermined time, which is assessed as sufficient for the user no longer having a finger in the irradiated area of the control panel, the disinfection process, disinfecting initiated.
- a particularly reliable and safe disinfection of the control panel is also achieved in this way.
- the switching device and/or control device can in particular be designed as an integrated component with the fastening device and/or visual protection device.
- an input device in particular a cashless point of sale and/or an ATM input device and/or an elevator button input device and/or an access code input device (e.g. a door) and/or a bell button input device (e.g. a door), with a disinfection device according to one of the described embodiments to form.
- the cashless point of sale can be wireless (that is, battery operated) due to the low power consumption of UV radiation sources designed as UV LEDs, or it can be wired.
- the access code input device can be, for example, a code lock on a door.
- the input device can also be assigned to any other device, particularly advantageously a device in public space, in which different users come into mechanical contact with the respective operating surface when making an input.

- the main plane of extent of the control panel 3 runs in the present case in the xy plane, from which the sight protection device 4 with two lateral flanks 4a, 4b and an upper screen 4c rises in the z direction.
- the control panel 3 has several keys 3x, which here are part of a numeric keypad with an additional function.
- the keys 3x form an essentially square-shaped keypad.
- the buttons 3x are partially arranged between the lateral flanks 4a, 4b of the visual protection device 4, and partially next to the in the right flank 4b of the figure, so that the right flank 4b is arranged between two subsets of the keys 3x.
- buttons 3x of the control panel are preferably arranged between the flanks of the visual protection device 4, ie within the visual protection device 4, in order to shield the radiation and structurally prevent a user from looking into the UV radiation sources.
- the UV radiation sources embodied as UV LEDs 6 are each arranged in the edge region of the visual protection device 4 and thus the fastening device 5 that is furthest away from the control panel 3 in the z direction, i.e. arranged at a distance from the control panel 3 in the z direction in order to Irradiate keys 3 times with the disinfectant radiation at the widest possible angle.
