Description

Devices for hand disinfection, their use and controls method

technical field

The present invention relates in a first aspect to a device for hand sanitiser, for example so that a person, hereinafter referred to as the user, can apply a hand sanitiser to one or more hands of the user.

Furthermore, the invention relates in a second aspect to the use of such a device.

Still further, the invention relates in a third aspect to a method of controlling a device for hand disinfection.

Background technique

Although the use of hand sanitizers has been known for many years, especially in medical, antiseptic and hospital settings, and in food manufacturing facilities, among other things, in recent years due to the outbreak of certain diseases and epidemics, especially due to the COVID-19 epidemic, The importance of hand sanitization has increased significantly, which makes people in general and globally in everyday situations, such as when shopping, commuting, traveling, visiting and/or working in restaurants, hotels, factories, etc., and generally Increased hygiene measures must be taken when visiting public places, buildings, institutions, etc.

Known devices for facilitating hand disinfection are manually operable by the user, for example by placing one hand under an outlet, nozzle, pipe, etc., and operating a push rod, lever, etc. The pump, which then delivers a portion of the hand sanitizer to the hand placed under the outlet, nozzle, tube, etc. Thereafter, the user may distribute the hand sanitizer over the hands and may rub the hand sanitizer onto the surface of the hands in order to achieve the desired sanitizing effect. In addition, devices for facilitating hand disinfection are known, for example, these devices are more or less automated based on various sensors for detecting the presence of the user's hand or hands under the exit, after which power-operated The pump delivers a portion of the hand sanitizer to the user's hands. Likewise, the user must then distribute the hand sanitizer over the hands and rub the hand sanitizer onto the surfaces of the hands to achieve a satisfactory sanitizing effect.

Therefore, in any case, when using known hand sanitizing devices, the user must stop, e.g. When a portion of the hand sanitizer has been delivered, the user typically remains standing while the sanitizer is dispensed and rubbed on the hands. This therefore means that each user typically occupies such a hand sanitizing device for a period of time before the next user can use the device. Thus, the hand sanitizer will create a barrier at e.g. an entrance, disrupting the inflow of people, and may easily form queues at e.g. Sanitizing hands is detrimental to the optimal health of society as a whole.

It should also be noted that, with regard to the more or less automated known hand disinfection devices, the sensors and/or control arrangements used are of a type that does not provide A quick release of hand sanitizer, the effect of which is that a potential user who holds one hand under e.g. Believing that the device is empty, the hand is removed before the hand sanitizer is released, after which some of the sanitizer is released (and wasted), and thereafter, the user then places the hand under the nozzle again, etc.

An example of an automatic dispenser for hand sanitizer is disclosed in US 2012/0085780 A1, which relates to a device powered by a rechargeable battery pack which can be recharged via a solar cell unit. The sterilant is stored in a fluid storage bag from which fluid sterilant can be delivered via a dispensing nozzle to a location above the lower tray, which is arranged to catch any excess sterilant fluid. The device is a sensor activated by a sensor that detects the positioning of the hand between the dispensing nozzle and the tray. Therefore, when using this prior art device, the user needs to stop in front of the device, reach into the space between the dispensing nozzle and the tray with the palm facing up, and wait for the disinfectant A portion of the antiseptic is delivered into the palms, and the disinfectant is then dispensed onto the surfaces of the hands by, for example, rubbing the hands. The user may start walking away along the intended route while e.g. handing out sanitizer and wiping hands, but many will remain still for a short period of time before bypassing or exiting the hand sanitizing device, and when entering e.g. buildings, houses , shops, etc., where such a prior art disinfection device is placed, and as expected, everyone who needs to enter such a building, house, shop, etc. uses it, the speed of the owner will at least slow down.

According to an embodiment, the spraying means may comprise one or more nozzles arranged at each side of said disinfection zone.

Thereby, the spraying means can be arranged such that the nozzles are placed in such a way that the entire surface of the user's hand can receive a spray of disinfecting liquid, or can come into contact with a spray of an aerosol, eg provided by an array of nozzles. In this case it should be noted that the nozzles are manufactured and designed to correspond to the pressure of the sterilizing liquid being delivered, so that the liquid can be sprayed in a suitable manner, for example as sprays or bursts of the spraying liquid, or as a mist out, for example in the form of an aerosol. It should also be noted that where the sanitizing liquid is ejected as a spray, such as a burst of spray, and due to the fact that said spray is directed towards the user's hands in a relatively limited space (i.e. the sanitizing zone), most The spray will be applied to the user's hands, including the otherwise rather inaccessible skin areas of the hands, as explained above, without substantially forming excess liquid. When the disinfecting liquid is applied in the form of, for example, a spray suspended in air (e.g. an aerosol), any aerosol that may not reach the user's hands will evaporate and virtually no excess liquid will fall on e.g. the device, Wait on the floor. However, in the rare event that any liquid droplets should fall onto the bottom of the dispenser head, a grid or the like may be placed there to collect and contain this excess liquid.

According to an embodiment, the spraying means may comprise one nozzle arranged at each side of the disinfection zone, for example close to the lower part of the disinfection zone, and directed at an upward angle, for example between 0° and 90° relative to the vertical. ° or within an angle of 5° to 85°, or the angle may, for example, be in the interval of about 30°, in the angle interval of about 45° or in the angle interval of about 60° relative to the vertical direction or within other suitable angle intervals.

It should be noted that in embodiments of the invention, the sanitizing liquid is delivered by a pump to the nozzle at a pressure which causes the sanitizing liquid to be sprayed in a predefined manner, for example as a spray or burst of spray liquid, or as a mist, For example as an aerosol, in either case. Such pressure may be a pressure of up to 5 bar, or may be higher than 5 bar, higher than 6 bar, higher than 8 bar, higher than 10 bar, etc. As an example, it is mentioned that the pressure may be in the interval from 6 bar to 8 bar, or in the interval from 8 bar to 12 bar, etc. However, the pressure may depend on the actual sterilizing liquid used and/or the actual nozzle used.

Furthermore, it should be noted that the combination of pressure and duration of delivery of the disinfecting liquid to the nozzle is important when providing the desired spray of disinfecting liquid, for example, as a spray or burst of spray liquid, or as a burst of an aerosol, to Delivering a spray that helps achieve a sanitizing effect, such as a short duration combined with high pressure.

Furthermore, it should be noted that devices according to embodiments of the invention may include additional indicators for maintenance purposes, such as indicator lights, such as indicators to alert personnel maintaining the processing device, such as low disinfection levels, low power levels, etc. device. Thereafter, the person in charge can replace the sterile liquid container, such as a bag, replace the battery pack, etc. or perform other maintenance work.

It should be noted in this regard that, according to an embodiment, the device is capable of communicating with other devices, communication means, etc., for example via a Bluetooth connection, via a Wi-Fi connection, etc., and thus the need to replace the sterile fluid bag may be in this way ( e.g. via Internet connection, via Bluetooth connection, etc.) to the person in charge.

According to an embodiment, said spraying of said sanitizing liquid may comprise a spray of said sanitizing liquid.

Thus, it can be achieved that when the hand is in the disinfection zone, the spraying tool for spraying the disinfection liquid will direct the spray towards both sides of the hand under the control of the control unit, such as an aerosol comprising the disinfection liquid, an aerosol A curtain or the like, thereby forming a film of the sanitizing liquid on the surface of the hand. It should be noted that since the antiseptic liquid is directed towards the hands as a spray, e.g. an aerosol comprising antiseptic liquid, for example the aerosol will flow into and through the air and reach areas otherwise difficult to reach by spraying, For example, the skin area between the user's fingers, etc. An improved disinfection effect is thus achieved thereby.

It will be appreciated that the user may be stationary while using the device, but with the sanitizing zone substantially vertically oriented, and since the control unit is used to provide the right amount of sanitizing liquid at each hand as they pass by, The user can conveniently use the device while walking by. After passing the device, the user can wipe their hands, which enhances the sanitizing effect, e.g. due to the distribution of the liquid, but since the sanitizing liquid is applied in spray form, e.g. bursts of spray that provide a membrane on the hands, so that there is no rubbing afterwards Satisfactory disinfection of hand cases is achieved.

According to an embodiment, the disinfection zone may be configured to receive a user's hand oriented in a substantially vertical direction.

Thus, in combination with this embodiment of the device according to the invention, it is achieved that the user can use the device while passing the device, for example, by walking past the device and conveniently allowing the hand close to the device to enter the disinfection zone and come out again. It will be appreciated that the device may be configured such that the sterilization zone will be at a height suitable for a wide range of people, for example a wide range of people around normal height.

However, it should be understood that a taller person may bend slightly, and a shorter person may raise the arms slightly (or more), whereby the hands are still oriented with the palms in a substantially vertical direction At the same time, it is possible to enter the disinfection zone, for example with a finger pointing slightly forward. Also, it should be understood that the user may raise the arm and bring the hand into the disinfection zone from above. Accordingly, it should be understood that persons of lower stature may also use the device, such as children, wheelchair users, and the like.

In general, it should be understood that the user will position and/or move the hands so that when in the disinfection zone, the palm will face one side of the disinfection zone, the back of the hand will face the other side, and the fingers will be substantially extended.

It should also be understood that when devices according to the present invention are configured to be placed where a potential user walks through, two or more devices may be placed at an appropriate distance from each other, which may allow the user to walk between them. Disinfect your hands from time to time.

It should be noted that when it is stated that the user's hand is oriented in a substantially vertical direction, it is understood that the hand may be in a relaxed state, such as away from the hand forming a planar structure that may be used to define a precise orientation and plane, Orientation is possible within a relatively wide range practically limited only by elements of the device for hand disinfection delimiting the disinfection zone, such as, for example, side walls or the like.

According to an embodiment, the disinfection zone may be configured to receive a user's hand oriented at an angle with respect to a substantially vertical orientation.

In a second aspect, the invention relates to the use of a device according to any one of claims 1 to 13, wherein said device is positioned at or near a pedestrian area, at or near a passing area, And wherein optionally, another one of said devices may be positioned at a distance from said device such that a user may pass between said device and said further device such that the user may pass by a Sanitize one or both hands.

As mentioned above, the user can use the device according to the invention when passing the device, for example, by walking past the device and letting the hand close to the device enter the disinfection zone and come out again. When devices according to the invention are configured to be placed where potential users walk, two or more devices may be placed at a suitable distance from each other, which may allow users to sanitize their hands while passing between them, Or the user may only sanitize one hand, for example if the user is holding something in the other hand. However, the option of sanitizing the hands is provided, which in this way can be performed in a relatively quick manner when passing between two devices.

In a third aspect, the invention relates to a method of controlling a device for hand sanitation, said device comprising a sanitizing zone configured to receive a hand of a user, said method comprising

- detection of the user's hand when entering the disinfection zone,

- 3-dimensional determination of the position within the disinfection zone, and

Detailed ways

An exemplary embodiment of a device 1 according to the invention seen in front view is shown schematically in FIG. 1 . In this embodiment, the device is configured for standing, eg on the floor, and has a base frame 2 standing on a support 4 , wherein the base frame 2 carries a dispenser head 12 . This dispenser head 12 defines a disinfection zone 6, which may for example be a zone in the form of a channel, a groove, etc., and into which a user's hand may be inserted, as will be explained later, for example with the hand and fingers pointing downwards and thus when When a person passes the device 1, the hand can pass through the zone 6, for example from the front to the rear. The dispenser head 12 can have two dispenser-side elements 10 which are arranged opposite one another to form the disinfection zone 6 . At these two distributor-side elements 10 , spraying means 8 are arranged as indicated in FIG. 1 , and as will be explained in more detail later, for example in the form of nozzles or the like. When passing through or otherwise emerging in the sanitizing zone 6, the spraying means 8 are used to spray a burst of sanitizing liquid or a spray of sanitizing liquid onto the user's hands such that, for example, a film of sanitizing liquid is substantially received in the on all accessible surfaces of the hand. The burst of disinfecting liquid sprayed by the spraying means 8 or the spraying of the disinfecting liquid is such that essentially no excess disinfecting liquid is formed, for example falls to the bottom of the disinfecting zone 6 . However, if any excess sterilizing liquid forms, this can escape via small holes, small grates etc. (not shown in Figure 1 ) in the bottom of the sterilizing zone 6 . Furthermore, as indicated in FIG. 1 , the supply of sanitizing liquid may be included in a container, such as a flexible bag 18 , which may be placed in the interior of the base frame 2 . The base frame may contain one or more of such flexible bags 18 or other forms of containers for sanitizing liquids.

As further indicated in FIG. 1 , the device 1 may comprise sensor means 14 , eg arranged in the dispenser head 12 , for detecting when a potential user approaches the device and/or when a user's hand enters or is about to enter the disinfection zone 6 . In addition, the sensor device 14 may be used to detect when the user's hand has left or is about to leave the disinfection zone 6, respectively.

Still further, the device 1 may include one or more indicators 16, such as lights such as LED lights, which may be used to draw a potential user's attention to the device 1 and/or may be used to indicate to a potential user how to use the device. device. Such indicators, indicator lights, indicator light panels etc. are visible to the user eg from all directions in a 360° configuration.

The function of the device according to an embodiment of the invention will be explained with reference to Fig. 2, which shows an example of components of the device 1 in a schematic way.

The device includes a supply of sterilizing liquid 20 which, as described above, may be arranged in the base frame 2 as one or more bags 18 . The supply of sterilizing liquid 20 is connected via eg a pipe or tube to a pump 22 which may be placed in the dispenser head 12 or possibly in the base frame 2 . When it is desired to provide a burst of sanitizing liquid or a spray of sanitizing liquid, the pump pressurizes the sanitizing liquid and pumps the liquid via a pipe or tube to a spraying means 8 which, as mentioned above, may include a Nozzles for outbreak or sanitizing spray. It should be noted that the pump 22 can provide the necessary pressure when necessary, for example when a hand is detected in the disinfection zone 6, or the pump can be configured to maintain a certain pressure at all times so that, for example, by allowing already pressurized liquid to reach Spraying the means 8 to provide a burst or a mist of the sanitizing liquid may have the effect, for example, that the mist will form faster and less excess liquid will form. Therefore, it should be understood that a controllable valve or the like (not shown in FIG. 2 ) could be arranged between the pump 22 and the spraying tool, which would be controlled by the control unit 24 to operate at a specific pressure for a specific period of time. Deliver the disinfectant liquid within a certain period of time.

Furthermore, in Fig. 2, a power supply 26 is shown, which may be in the form of a battery pack. This power source is connected to the pump 26 and may power other components such as the control unit 24 , the sensor device 14 and the indicator(s) 16 . Possibly, power can be provided to other components. For example, the power source 26 may be connected to a supply of sanitizing liquid 20 to power the supply meter. However, it will be apparent to those skilled in the art that such a supply meter for indicating the remaining liquid quantity can be powered directly from the control unit 24 which in any case needs to be connected to the supply source 20 in order to indicate the remaining liquid quantity. liquid volume.

However, it should also be noted that, in order to estimate the remaining content of the sterile fluid supply, for example, the control unit can count the number of bursts of sterile fluid that have occurred since the last replacement of the sterile fluid bag, and in this way estimate the remaining content of the sterile fluid supply. how much liquid. Alternatively, the control unit may keep a count of burst durations in case they sometimes differ, eg by adding the period of time the pump has been applied, and in this way estimate how much liquid is left. It will be apparent to those skilled in the art that other ways of doing this are possible.

As also shown in Figure 2, a control unit 24 is connected to the pump 22 for controlling the pump and certain signals may be sent from the pump 22 to the control unit, such as a pressure indicator signal or the like. In addition, the control unit 24 is connected to indicator(s) which can send a signal back to the control unit.

It should be noted that the pump 22 is configured to supply the sterilizing liquid at a pressure which will cause the sterilizing liquid to be sprayed as a burst of sterilizing liquid or as a spray, eg as an aerosol from the spraying means 8 . Such pressure may be, for example, a pressure of up to 5 bar, or it may be higher than 5 bar, higher than 6 bar, higher than 8 bar, higher than 10 bar or even higher. As an example, it is mentioned that the pressure may be in the interval from 6 bar to 8 bar, or in the interval from 8 bar to 12 bar, etc. However, the pressure may depend on the actual sterilizing liquid used and/or the actual nozzle used. Furthermore, it should be noted that when providing bursts of a disinfecting liquid (e.g. aerosol) to deliver a spray for achieving a disinfecting effect, the combination of pressure and duration of disinfecting liquid delivery to the nozzle is important, e.g. short duration versus The combination of high pressure, for example, can deliver a burst of aerosol that will flow into and through the air to the surfaces of the user's hands, including the skin surfaces between the fingers and other skin surfaces that might otherwise be difficult to reach by spraying. Furthermore, by using high pressure for a short duration to create bursts of sanitizing liquid, such as a spray, it is achieved that aerosols that may not reach the user's hands will travel through the air and eventually evaporate, thus leaving no excess and effectively The ground does not drip.

The specific time period during which pressure is delivered to the nozzles and the spraying means (eg nozzles) spray bursts or sprays of disinfecting liquid into the disinfecting zone from at least two directions may be referred to as application time period T _a . The application period T _a may be, for example, up to 0.1 seconds, more than 0.1 seconds, more than 0.2 seconds, more than 0.5 seconds, more than 0.8 seconds or more than 1.0 seconds.

Still further, it should be noted that, according to an embodiment, the apparatus is capable of communicating with other devices, communication means, etc., for example via modules (not shown) for Bluetooth connections, Wi-Fi connections, etc. Thereby, any service signal, such as the need to change the sterile fluid bag, low battery voltage, etc., can be communicated in this way (eg via Internet connection, via Bluetooth connection, etc.) to the person in charge, including the ID of the specific device. Furthermore, it should be noted that when more than one device 1 is used, the various devices 1 may communicate with each other. For example, an indicator may be activated at one or more of the other devices based on sensor input received at one device.

Furthermore, it should be noted that, according to embodiments, the device may include means for preventing the loss of the device, such as a tracking device (not shown) incorporated into the device, which makes it possible for the device to be misplaced or stolen. The device can be retrieved under the circumstances.

Furthermore, it should be noted that more than one particular type of assembly may be included in the example shown in Figure 2, such as two or more pumps, two or more battery packs, two or more control unit etc.

FIG. 10 shows a user 32 disinfecting a hand 30 in the device 1 according to the invention, wherein the user passes his hand 30 through the disinfection zone 6 while the hand is oriented in a substantially vertical direction. As the hand passes, the spraying means directs the burst of the disinfecting liquid or the spraying of the disinfecting liquid from at least two directions, for example nozzles placed at each side of the disinfection zone, for example nozzles placed at each of the dispenser side elements 10. The spray is sprayed into the disinfection zone, for example for an application period T _a . The period of application T _a may be, for example, up to 0.1 seconds, greater than 0.1 seconds, greater than 0.2 seconds, greater than 0.5 seconds, greater than 0.8 seconds, or greater than 1.0 seconds.

Figure 11 corresponds to Figure 8, but in Figure 10 shows a vertical plane 56 (also shown in Figure 5) and therein shows a spray burst from each of the two nozzles 50 located in the disinfection zone 58, and the spray burst sprays the sanitizing liquid on the user's hands from two directions, for example from each side. The spray can be directed at a more or less upward angle, for example in the angular interval 0° to 90° or in the angular range 5° to 85° relative to the vertical 56, or the angle can be directed, for example relative to the vertical Straight direction 56 is within an angular interval of about 30°, about 45°, or about 60° or within other suitable angular intervals.

Fig. 12 shows an example of using the device 1 according to the invention at a location where many people pass by. The devices are positioned at an appropriate distance from each other so that the user 32 can pass between the devices so that the user 32 can sanitize one or both hands as they pass. It should be noted that when used in places such as airports, the device can also be used for guide posts and as anchor points for eg guide strips and similar marking implements.

Figures 13a to 13c illustrate some of the various ways in which the device for hand disinfection can be used, for example, as illustrated by a schematically shown dispenser head 12, viewed from one side, for example showing dispensing side element 10, and as illustrated by a user's hand 30. In FIG. 13 a , the user enters the user's hand 30 from the left, keeping the hand substantially vertical with the fingers pointing downwards and with the hand substantially parallel to the dispenser side element 10 . As indicated by the arrows, the user passes hand 30 from left to right so that the hand passes through the disinfection zone.

In Fig. 13b, it is shown that the user's hand 30 is accessible from above, for example with the fingers pointing downwards, and when the spray tool (not shown in Figs. , the user may withdraw the hand 30 upwards, for example as indicated by the double arrow.

In Fig. 13c, it is also shown that the user can bring his or her hand 30 into the disinfection zone by moving the hand downwards in an angular movement, for example where the palm is substantially parallel to the dispenser side element 10, until the hand is received in the disinfection zone. in the disinfection area. When the spray tool (not shown in FIGS. 13a-13c ) has sprayed a burst or spray of antiseptic liquid onto the hand 30, the user can again angle the hand 30 back upwards, for example, as indicated by the double arrow.

Other ways of using the device for hand disinfection are also applicable, such as combinations of the ways illustrated in Figures 13a to 13c.

Figure 14 shows in a schematic manner the components of an embodiment of a disinfection device according to the invention, wherein it is illustrated that a bag 18 for a disinfection liquid is connected to a pump via a filter 60 for removing possible particles, contaminants, etc. twenty two. Via pipe 54 etc., the sanitizing liquid is led to a two-way controllable valve 62 which is controlled by a control unit (not shown). The two outlets of the two-way controllable valve 62 are connected to distribution pipes 64 etc., which lead the sterilizing liquid to the nozzles 50 in the sterilizing zone 6 , possibly via a further filter 60 .

Figure 15 illustrates an embodiment of a disinfection device according to an embodiment of the invention seen from above, for example showing the profile of the dispenser head 12 seen from above, and wherein, seen from above, additionally indicates Two distributor side elements 10 . Inside each of these is located a sensor device 40 which in this embodiment is a hand detection system based on 3D positioning in an electric field. The E-field sensor devices are enclosed in the dispenser-side element 10 and thus each have an encapsulation 11 protecting the sensor device 14 . The sensor device 14 according to this embodiment generates electric fields E_F_1 and E_F_2 which are generated by electric charges and propagate 3-dimensionally within the disinfection zone 6 . Furthermore, since two sensor devices 40 are placed facing each other on each side of the disinfection zone 6, the electric fields E_F_1 and E_F_2 can overlap, as indicated by E_F_1+2.

When the user's hand enters the disinfection zone 6, the position of the hand and the movement of the hand into the disinfection zone are detected in 3 dimensions. Thus, based on the signals from the sensor device 14, the device and for example the spraying tool 8 can be warned of the approaching hand and the characteristics of the movement, for example the speed at which the hand is entering, and can thus apply for example a disinfecting spray from the corresponding nozzle when the hand is in the appropriate position. Liquid burst.

Fig. 16a shows in a schematic way a sensor device 40 using electric field technology for detecting a user's hand. The sensor device 40 according to this embodiment comprises a transmitter 70 on one side of a spacer 72 (e.g., a dielectric material, layer, plate, etc.), and on the other side of the spacer 72 are positioned a plurality of receivers 74a, 74b. Below the emitter 70 a layer defining an electrical ground 76 is arranged.

When a voltage is applied to the electrodes, an electric field (E field) is generated, as illustrated in Figure 16a, with field lines 78 (dashed lines) and corresponding equipotential lines 80 (dotted lines), only shown for clarity one of them.

When the user's hand 30 enters the electric field, for example when the user's hand approaches or enters the disinfection zone, the electric field becomes distorted, as illustrated in Figure 16b. Due to the conductivity of the human body and because the human body represents a shunt to ground, electric field lines 78 are pulled towards the user's hand 30 . Thus, the impact of the user's hand 30 causes a compression of the isopotential lines, represented by the single isopotential line 80 in Figure 16b, which means that the signal level at the receiver electrode 74a is shifted to a lower potential, which can be Measured and utilized eg by a control unit (not shown in Fig. 16b) to calculate eg the position of the hand 30, to track movements etc.

Therefore, it should be understood that by applying such sensor devices 40 on or in the dispenser side element 10, based on the signals from these sensor devices 14, the device and for example the spraying tool 8 can be warned of an approaching hand 30 and movement. characteristics, such as the speed at which the hand enters, and thus a burst of, for example, a sanitizing liquid can be applied from the corresponding nozzle when the hand is in place.

Other embodiments of sensor devices may be used, which may operate using other technologies.

Fig. 17 shows various examples of the positioning of one or more sensor devices in the device 1 for hand disinfection, where the device is seen eg in a front view corresponding to Figs. 8 and 11 . The sensor device may be a sensor device using electric field technology for detecting the user's hand, as explained above in connection with Figures 15 and 16a-16b. Such a sensor device 14a can be positioned at a side of the disinfection zone 6, eg placed in the dispenser side element 10, where it can generate an electric field E_F_1. Alternatively or additionally, the sensor device 14b may be positioned at the other side of the disinfection zone 6, eg in another dispenser side element 10, where it may generate an electric field E_F_2, as illustrated in FIG. 17 . Still further, it is illustrated in Fig. 17 that the sensor device 14c may be positioned at the bottom side of the sterilization zone 6, eg placed in the bottom of the dispenser head, where it may generate the electric field E_F_3. It will be apparent that one or more of these sensor devices 14a, 14b and 14c may be used to detect a user's hand, e.g. a single sensor device, e.g. A sensor device combination, such as 14a and 14b, 14a and 14c or 14b and 14c, and possibly even a combination of three sensor devices.

It should be noted that other positions than those shown for one or more of these sensor devices 14a, 14b and 14c are possible.

In the above description, various embodiments of the present invention have been described with reference to the accompanying drawings, but it is obvious to those skilled in the art that the present invention can be implemented in infinitely many ways, such as using in various combinations Examples disclosed in the specification, and within the scope of the appended claims, are within a wide range of variation.
