[0088] Figure 1Figure 1 shows a schematic view of a device 100 according to an embodiment of the invention for disinfecting at least one room, in particular a room for one or more people. The room can be, for example, a medical or veterinary treatment room, in particular a hospital room, a patient room and / or an operating room, e.g., of a hospital or a doctor's office.

[0089] The device 100 comprises an atomizer for a disinfectant for disinfecting the room and is characterized, for example, by the fact that the atomizer includes a rotatable bell plate 1 for atomizing the disinfectant into the room.

[0090] An electric motor 2 or an air turbine is provided to drive the bell-shaped disc 1 and thus set it in rotation, by means of a hollow drive shaft S, which also advantageously serves to supply the disinfectant to the bell-shaped disc 1. A supply line is provided for this purpose in the hollow drive shaft S. The bell-shaped disc 1 is expediently fixed to the drive shaft S.

[0091] The bell-shaped plate 1 interacts with a disc-shaped plate P, which advantageously rotates with the bell-shaped plate 1. The bell-shaped plate 1, the drive shaft S, and the plate P are arranged essentially coaxially with each other.

[0092] The disinfectant exiting from a disinfectant nozzle D of the drive shaft S hits the rotating plate P and is thereby distributed by centrifugal force onto an inner surface 1a of the rotating bell plate 1 ( Figure 9), from where the disinfectant is directed to a ring-shaped bell-shaped spray edge E, from where it is atomized and sprayed into the room.

[0093] The bell plate 1 has a rotational speed of preferably at least 30,000 revolutions per minute and an atomization capacity of at least 50 milliliters per minute and / or at least 0.3 cubic meters per minute during operation.

[0094] Bell-shaped atomizers and their operating principle, particularly with a rotating plate, are common in the technical field of automotive body painting using rotary atomizers, so reference can be made to that section for further details. The bell-shaped atomizer serves to atomize the paint and deliver it in a spray jet to create a painted surface on the vehicle body.

[0095] A first blower 3 is advantageously arranged upstream of the bell-shaped disc 1, while a second blower 21, preferably designed as a side blower, is arranged downstream of the bell-shaped disc 1. The blowers 3 and 21 serve to transport and distribute disinfectant atomized by the bell-shaped disc 1, so that the atomized disinfectant can be distributed as optimally as possible in the room. This ensures that the disinfectant reaches as many surfaces as possible to be disinfected (e.g., walls, ceilings, furnishings, surfaces facing away from the room, etc.). The blowers 3 and 21 can, for example, have a combined air flow rate of over 200 or even over 300 cubic meters per hour.

[0096] The bell plate 1, the electric motor 2 or the air turbine and the blower 3 are housed at least partially in an atomizer housing Z.

[0097] A disinfectant line L1, encompassing the drive shaft S, connects the bell plate 1 to a connecting device V. The connecting device V serves to connect to a container 4 for holding the disinfectant. The disinfectant line L1 thus serves primarily to supply the disinfectant 1 to the bell plate 1. A conveying device 10, e.g., a pump, serves to convey and meter the disinfectant.

[0098] The device 100 comprises two flow measuring devices 11a, 11b for measuring a volumetric flow rate, in particular of the disinfectant.

A second flow measuring device 11b is arranged between the conveying device 10 and the bell-shaped disc valve 9 located downstream of the conveying device 10.

[0099] At least one dehumidifier 14 is used to dehumidify the air in the room, particularly after the disinfectant atomization has finished. The dehumidifier(s) 14 preferably have a total dehumidification capacity of over 600 or over 700 cubic meters per hour.

[0100] A receiving container 13, e.g. in the form of a tub, serves to collect and recover loss material generated by the disinfection process.

[0101] The receiving container 13 is connected to the atomizer housing Z via a funnel 12 in order to be able to receive liquid that is deposited on or in the atomizer housing Z, in particular deposited from the disinfectant.

[0102] The collection container 13 is also connected to the dehumidifier 14 in order to be able to collect liquid that the dehumidifier 14 extracts from the room air.

[0103] The receiving container 13 is also connected to the conveying device 10 via a line L3, so that liquid can be supplied to the receiving container 13 when there is overpressure at a pressure relief valve 18 located in the line L3. Alternatively, the pressure relief valve 18 can also be located in the disinfectant line L1, e.g., between the conveying device 10 and the bell plate 1, in particular at or next to the second flow meter 11b, or at or in the conveying device 10.

[0104] The device 100 comprises a loss medium line L2, wherein the receiving container 13 can be emptied via the loss medium line L2 and is preferably connectable to the connecting device V, so that loss medium from the receiving container 13 can be supplied via the connecting device V e.g. to the disinfectant container 4 previously emptied in the disinfection process or to another container for disposal.

[0105] The loss medium passes through the following on its way from the receiving vessel 13 to the connecting device V: a filter device 16 for filtering the loss medium, the conveying device 10, a receiving vessel valve 7, which is arranged downstream of the filter device 16 and upstream of the conveying device 10, a loss medium return valve 8, which is arranged downstream of the conveying device 10 and upstream of the connecting device V, and the flow measuring device 11b.

[0106] A detergent connection A serves to connect to a detergent container 15 for receiving a detergent in order to flush at least sectionally the disinfectant line L1 and / or the waste line L2 in a flushing mode.

[0107] The detergent connection A can be connected to the disinfectant line L1 via a detergent line L4, wherein the detergent line L4 includes a detergent valve 6 before opening into the disinfectant line L1.

[0108] The device 100 can therefore not only be operated in a disinfection mode, but can also be operated in a recovery mode for recovering loss medium generated by the disinfection process and in a rinsing mode for at least partially rinsing the disinfectant line L1 and preferably the loss medium line L2.

[0109] The conveying device 10 is universally applicable. In disinfection mode, the conveying device 10 is used to convey the disinfectant from the disinfectant container 4, in recovery mode to convey the lost substance from the receiving container 13, and in rinsing mode to convey the rinsing agent from the rinsing agent container 15.

[0110] The waste fluid line L2 connects to the disinfectant line L1 at two junctions P1 and P2.

[0111] The node P1 is located between the conveying device 10 and the bell-shaped valve 9 located in the disinfectant line L1 downstream of the conveying device 10.

[0112] The node P2 is located between the conveying device 10 and a disinfectant valve 5 located in the disinfectant line L1 upstream of the conveying device 10.

[0113] The detergent line L4 connects to the disinfectant line L1 at a junction P3, the junction P3 being located between the conveying device 10 and the disinfectant valve 5 located upstream of the conveying device 10 in the disinfectant line L1.

[0116] A humidity measuring device 19, e.g., with a control effect on the disinfection process of the device 100, is provided, wherein the humidity measuring device 19 serves to measure humidity in the room. For example, the disinfection process can be stopped if an insufficient increase in humidity in the room is detected during the atomization process.

[0117] A temperature measuring device 20, e.g., with a control effect on the disinfection process of the device 100, is provided, wherein the temperature measuring device 20 serves to measure a temperature in the room.

[0118] A level measuring device 17a is used to measure the fill level in the receiving container 13, while a level measuring device 17b is used to measure the fill level in the detergent container 15. Similarly, a level measuring device can, for example, be used to measure the fill level in the disinfectant container 4.

[0119] A room measuring device (not shown) is used to measure the room, whereby, depending on the measurement data of the room measuring device, the disinfection process of the device 100 takes place (e.g., adjustment of the dosage of the disinfectant, the volume flow of the at least one blower 3, 21 and / or the process time, etc.) or the initiation of a disinfection process of the device 100 is prevented, e.g., if the room measuring device determines that the device 100 is positioned unsuitably in the room or that the room is unsuitable for disinfection by the device 100.

[0120] The device 100 may also include one or more detection devices (not shown) for detecting the disinfectant, the detergent, and / or the rotational speed of the bell plate 1. The device 100 may, for example, be configured to interrupt or prevent its operation (e.g., to stop it or not start it in the first place) if the detection device detects an unsuitable disinfectant, an unsuitable detergent, and / or an unsuitable rotational speed of the bell plate 1.

[0121] Figure 2 shows a schematic view of the device 100, in particular to illustrate a disinfection process / mode according to an embodiment of the invention.

[0122] The disinfection process essentially works as follows: The electric motor 2, the blower 3 and the temperature measuring device 20 are activated and operate based on process values ​​for the disinfection process.

[0123] The disinfectant valve 5 and the bell-shaped valve 9 in the disinfectant line L1 are opened. The pumping device 10 is activated, so that the disinfectant is pumped from the disinfectant container 4.

[0124] After a predefined time interval of x seconds, the flow meters 11a and 11b detect the volume flow of the disinfectant. If no volume flow or an insufficient flow is detected, the disinfection process is stopped immediately.

[0125] The blower 3 draws air from the surroundings and uses it to distribute atomized disinfectant in the common room.

[0126] The pressure relief valve 18 protects the device 100 from excessive pressure.

[0127] The funnel 12 collects moisture that may be deposited on or in the atomizer housing Z during the disinfection process and directs it to the collection container 13.

[0128] After a predetermined time period (volume of disinfectant container 4 / flow rate) and when the flow meter 11a detects no flow, the disinfection process is complete. The pump 10 then stops running. The disinfectant valve 5 and the bell-shaped valve 9 in the disinfectant line L1 are closed. The electric motor 2 is switched off. The blower 3 then changes its operating mode as appropriate, for example, based on process values ​​for a dwell process and / or to cool the electric motor 2.

[0129] The disinfection process can create a relative humidity in the room of, for example, between 85% and 99%.

[0130] Figure 3Figure 1 shows a schematic view of the device 100, in particular to illustrate a loss medium recovery process / mode, according to an embodiment of the invention.

[0131] The refrigerant recovery process essentially works as follows: The refrigerant recovery process starts a predetermined time period before the end of the venting process of the dehumidifier 14.

[0132] Separated liquid from the atomizer housing Z, water from the dehumidifier 14 and possibly liquid from the line L3 (only in the case of overpressure in the line system of the device 100) are fed to the receiving container 13 as a loss medium.

[0133] The receiving container valve 7 and the leakage return valve 8 in the leakage line L2 are opened. The pumping device 10 begins to pump the leakage from the receiving container 13 to the previously emptied disinfectant container 4 or to another container.

[0134] The filter device 16 prevents the ingress of solid particles or generally unwanted parts into the piping system of the device 100.

[0135] When the flow meter 11b detects that there is no waste fluid flow, the waste fluid recovery process is complete. It should be noted that the waste fluid recovery process is preferably completed within the time required for the dehumidifier 14 to dehumidify the room.

[0136] The conveying device 10 stops running. The receiving vessel valve 7 and the waste medium return valve 8 in the waste medium line L2 are closed.

[0137] A small amount of loss medium may remain in the receiving container 13.

[0138] The level measuring device 17a checks whether the fill level in the receiving container 13 is correct. From this, it can be concluded whether the loss recovery process has been carried out correctly or not.

[0139] Figure 4 shows a schematic view of the device 100, in particular to illustrate a rinsing process / mode according to an embodiment of the invention.

[0140] The rinsing process essentially works as follows: The rinsing process starts after the dehumidification by the dehumidifier 14 has finished.

[0141] The electric motor 2 and the blower 3 start and operate based on process values ​​for the rinsing process.

[0142] The detergent valve 6, the wastewater return valve 8, and the bell-shaped valve 9 are opened. The pumping unit 10 begins to pump detergent from the detergent container 15.

[0143] The detergent is partially conveyed to bell plate 1 and partially back to disinfectant container 4, or to another container.

[0144] The detergent process is terminated after a predefined volume flow, e.g., after a predefined runtime of the pumping unit 10. The pumping unit 10 stops running. The detergent valve 6, the wastewater return valve 8, and the bell-shaped valve 9 are closed. The electric motor 2 and the blower 3 stop running.

[0145] A small amount of dish soap may remain in the plumbing system.

[0146] Figure 5shows a schematic view of a modified embodiment for the device 100 according to an embodiment of the invention.

[0147] A special feature of the in Figure 5 In the embodiment shown, a fixed detergent container 15 in the form of a refillable tank is attached to the detergent connection A, and a fixed disinfectant container 4 in the form of a refillable tank is attached to the connection device V.

[0148] Thus, in the context of the invention, the connecting device V and the detergent connection A can expediently be designed as permanent or detachable connections.

[0149] Figure 6 shows a schematic view of a modified embodiment for the device 100 according to an embodiment of the invention.

[0150] A special feature of the in Figure 6In the illustrated embodiment, the conveying device comprises a piston system 40 for conveying the disinfectant from the disinfectant container 4 and a piston system 150 for conveying the detergent from the detergent container 15. Consequently, there are two conveying devices (piston systems) 40 and 150. It is particularly preferred if the disinfectant container 4 is designed as a disposable container for inclusion in the piston system 40 and / or the detergent container 15 is designed as a disposable container for inclusion in the piston system 150.

[0151] Figure 7 shows a schematic view of a modified embodiment for the device 100 according to an embodiment of the invention.

[0152] A special feature of the in Figure 7The embodiment shown differs in that instead of two separate containers 4 and 15 for the disinfectant and the detergent, a single multi-container 50 is provided for holding the disinfectant for the disinfection process and additionally for holding detergent for the rinsing mode. This allows the multi-container 50 to be filled and operated first with the disinfectant for the disinfection process and then with the detergent for the rinsing mode. The conveying device is designed as a piston system 500, with the multi-container 50 integrated within the piston system 500. The multi-container 50 is integrated into the disinfectant line L1 and the detergent line L4 and can be connected to the connecting device V via the disinfectant valve 5 and to the detergent connection A via the detergent valve 6.

[0153] Figure 8shows a schematic view of a mobile transport housing 200 with a device 100 attached.

[0154] The transport housing 200 with the device 100 can be pushed into a work area by an operator. The operator can then activate the device 100 and subsequently leave the work area. After completion of the disinfection process, the operator can then transport the transport housing 200 with the device 100 to another work area to be disinfected. For this purpose, the transport housing 200 is part of a transport cart equipped with wheels.

[0155] The transport housing 200 exposes the bell-shaped disc 1 for atomizing the disinfectant, at least partially, with the receiving container 13 positioned below the level of the bell-shaped disc 1 and below the level of the blower 3, so that any spillage can be fed to the receiving container 13 by gravity. The transport housing 200 is lined with sound-absorbing material and includes a sealing plate to divide the interior of the transport housing 200 into a dry section and a wet section.

[0156] Figure 9 shows a cross-sectional view of a bell plate 1 and other components according to an embodiment of the invention.

[0157] The bell-shaped plate 1 is essentially funnel-shaped, with a base B (e.g., a plinth section), an inner surface 1a for the disinfectant, an outer surface 1b, and an annular splash guard E. The bell-shaped plate 1 interacts with a plate P. Reference numeral R denotes a gas guide ring with several leakage openings N. The gas is preferably air.

[0158] The inner surface 1a can be straight, concave or convex.

[0159] The outer surface 1b can be straight, concave or convex.

[0160] Base B is mounted so that it is fixed relative to the drive shaft S, allowing the bell plate 1 to be driven by the drive shaft S. Plate P is also fixed to the bell plate 1 so that it rotates with it. The hollow drive shaft S includes a hollow inner tube through which the disinfectant can be supplied to the bell plate 1, with the disinfectant outlet nozzle D being conveniently mounted on the inner tube.

[0161] The annular bell-shaped injection edge E can, for example, have a diameter of between 65 mm and 120 mm, preferably between 80 mm ± 10 mm, wherein an internal angle α of the inner surface 1a of the bell-shaped plate 1 can be, for example, between 5° and 45°, preferably between 30° ± 5°. An external angle beta of the outer surface 1b of the bell-shaped plate 1 can be between 1° and 80°. Preferably, the internal angle α is smaller than the external angle beta.

[0162] The inner surface 1a of the bell plate 1 can have a particularly ring-shaped edge area, wherein the edge area adjoins the bell plate injection edge E, has a width X of e.g. between 0.05 mm and 10 mm (preferably 2 mm + / - 1 mm) and preferably only the edge area is provided with a surface structure, but not the remaining part of the inner surface 1a.

[0163] The cross-sectional area for the disinfectant in the hollow drive shaft S can, for example, be between 3 mm and 30 mm.

[0164] In the disinfection process of the device 100, the disinfectant exiting the disinfectant nozzle D hits the rotating plate P, is distributed by the rotating plate P onto the rotating inner surface 1a and passes over the rotating inner surface 1a to the rotating bell-shaped spray edge E, from where the disinfectant is atomized and released into the room.

[0165] The gas guide ring R with the leakage openings N is arranged such that gas emitted from the leakage openings N passes over the outer surface 1b of the bell plate 1 onto the disinfectant emitted by the bell plate 1 in order to shape the disinfectant and / or reduce its droplet size.

[0166] The disinfection process essentially proceeds as follows: The disinfectant is guided through the drive shaft S and sprayed from the disinfectant outlet nozzle D of the drive shaft S. It strikes the plate P at a defined distance and, due to centrifugal force, is directed through a defined gap between the bell-shaped disc 1 and the plate P onto the inner surface 1a of the bell-shaped disc 1a. The special geometry of the disinfectant outlet nozzle D and its defined distance from the plate P ensure that the disinfectant is completely supplied to the defined gap. This guarantees a homogeneous distribution on the inner surface 1a. Due to the centrifugal force resulting from the rotation, the disinfectant is guided along the specially angled inner surfaces 1a towards the bell-shaped disc spray edge E.At the bell-shaped spray plate edge E, the disinfectant is atomized into the finest droplets. Due to the special geometry of the bell-shaped spray plate edge E and in conjunction with the gas flow from the gas guide ring R, the described process is improved, in particular the droplet size is reduced.

[0167] The gas flow is improved by the special geometry of the outer surface 1b and the radius of the bell-shaped injection plate edge E. The molding gas is preferably supplied by a fan, flows upwards along the drive shaft S, and surrounds the outer surface 1b. The special geometry of the gas guide ring R directs the molding gas onto the outer surface 1b with virtually no turbulence. Furthermore, the gas guide ring R reduces noise by preventing air turbulence in the lower area of ​​the outer surface 1b, which is covered by the gas guide ring R.

[0168] The Figures 10 and 11Figure 1 shows two different perspective views of a bell-shaped disc 1 according to an embodiment of the invention. The bell-shaped disc 1 serves to atomize a disinfectant for disinfecting at least one room occupied by one or more people and can be designed as disclosed herein.

[0169] It should also be mentioned that, for example, the disinfectant disclosed in US 2014 / 0119992 A1 and / or other suitable disinfectants can be used to eliminate, in particular, bacteria, viruses, germs and / or fungi, etc. The disinfectant is specifically a liquid disinfectant.

[0170] It should also be mentioned that the room should preferably be a room accessible to one or more people. Reference symbol list
