detailed description

The invention will be understood from the following description, in which reference is made to the accompanying drawings.

FIG. 1 schematically illustrates an inter-person interaction device deployed in a LV building. The BT building is partitioned, it has two rooms P1 and P2 separated by a CL partition. The partition CL is coupled to an inter-person interaction device 1. By way of example, a visitor A who is in room P1 can interact, for example talk to a resident B who is in room P2 at the through the inter-person interaction device 1. The inter-person interaction device 1 is open, which makes it possible to establish an almost normal interaction zone IT between the visitor A and the resident B, that is to say say without physical barriers and without any particular measures on the part of people. The inter-person interaction device 1 comprises a barrier BA which prevents any mutual contamination by bacteria, viruses, germs or even insects/parasites, that is to say that the bacteria, viruses, germs and insects /parasites are prevented from moving from one room to another, from P1 to P2 and from P2 to P1. The building BT can be an existing structure, for example a retirement home in which a room intended to be a visiting room has been partitioned off and provided with an inter-person interaction device 1 according to the invention. The LV building can also be a temporary structure, for example an CBRN tent (i.e. nuclear, radiological, biological and chemical) or any other removable temporary structure separated in the form of two rooms and provided at the level of the partition wall with a inter-person interaction device 1 according to the invention.

FIG. 2 schematically illustrates an inter-person interaction device 1 and its principle of operation.

The inter-person interaction device 1 comprises a suction part AS, a frame 8 defining a window 9 and an evacuation part EV. The suction part AS has a suction mouth 2, a suction motor 3, a suction disinfection module 4, a first Y pipe connector 5, an air curtain diffusion module 6, one or more inlet pipes 7 connecting the previous elements 2, 3, 4, 5 and 6. Optionally, the air curtain diffusion module 6 can integrate a diffusion disinfection module 16, and the mouth of suction 2 can integrate a filter. The evacuation part EV comprises an air curtain recovery module 10, a second Y-shaped pipe connector 11, an evacuation disinfection module 12, a vacuum motor 13, an evacuation mouth 14, and one or more evacuation pipes 15 connecting the previous elements 10, 11, 12, 13 and 14.

The operation of the inter-person interaction device 1 is as follows. Air AI is sucked in by the suction mouth 2 under the action of the suction motor 3. The air sucked in AI can come from one of the two rooms P1 or P2, or from the two rooms P1 and P2 or from outside the BT building. AI intake air is considered potentially contaminated. The aspirated air AI passes through the suction disinfection module 4 to be treated there, i.e. decontaminated/sanitized/purified. It may be a treatment with hydrogen peroxide, or ozone, or UV (ultraviolet radiation), or UVC (ultraviolet radiation at 254 nm), or alcohol vapour, or a combination of said aforementioned means, or other known means for substantial destruction of bacteria, viruses, germs or even insects/parasites. By way of example, the suction disinfection module 4 advantageously uses treatment with hydrogen peroxide or alcohol vapor. The sanitized air AA from the suction disinfection module 4 is then directed to the air curtain diffusion module 6 via the first Y-shaped pipe connector 5 and two inlet pipes 7. The module air curtain diffusion 6 has the function of generating a flow of air which sweeps the window 9 over its entire width from top to bottom and which forms a curtain of sanitized air RI. The air curtain diffusion module 6 can integrate a diffusion disinfection module 16 which completes the treatment of the air before its diffusion as a sanitized air curtain RI. It may be an ozone generator compact enough to be integrated directly into the upper part of the air curtain diffusion module 6. Persons A and B can interact through this window 9, it that is to say through the curtain of sanitized air RI which constitutes the barrier BA mentioned in relation to FIG. 1. Any contamination such as bacteria, viruses, germs or even insects/parasites emitted by person A or B or being in one of the rooms P1 or P2 are prevented from passing through the sanitized air curtain RI and is captured by the air curtain to be directed downwards in the direction of the air curtain recovery module 10. It should be noted that the use of an alcohol vapor treatment allows in the case where sputters were emitted through the window (e.g. during a sneeze) to include the sputters in the alcohol vapors which will ensure their disinfection beyond the air curtain. Potentially contaminated air AC is recovered at the bottom of window 9 by air curtain recovery module 10 and then directed to exhaust disinfection module 12 through second Y-pipe connector 11 and two evacuation pipes 15. The recovered air passes through the evacuation disinfection module 12 to be treated there, that is to say decontaminated/sanitized/purified. It may be a treatment with hydrogen peroxide, or ozone, or UV, or UVC, or alcohol vapor, or a combination of the aforementioned means, or other means known for a substantial destruction of bacteria, viruses, germs or even insects/parasites. By way of example, the evacuation disinfection module 12 advantageously uses a UV or UVC lamp treatment that is compact enough to be integrated directly into the lower part under the air curtain recovery module 10. The air from the evacuation disinfection module 12 is then directed to the exhaust vent 14 in the form of a sanitized exhaust air AO. The vacuum motor 13 makes it possible to create a vacuum below the window 9 to generate suction from the air curtain RI of the air curtain recovery module 10 towards the exhaust outlet 14. The evacuated air AO can be evacuated to one of the two rooms P1 or P2, or to the two rooms P1 and P2 or to the outside of the BT building. The exhaust air AO is considered treated. Consequently, the operation of the inter-person interaction device 1 also has a function of disinfecting the air of one or more rooms when the air is taken from it at the inlet and then returned to the outlet of the device. Optionally, depending on the type of air treatment carried out for disinfection and/or when the air is evacuated in the rooms, a regulation module 17 can be provided upstream or downstream of the vacuum motor 13. The regulation module 17 prevents the evacuated air AO from containing too large a proportion of chemical product having been used to treat the air. The regulation module 17 can be a condenser if a treatment uses alcohol vapors in order to prevent the evacuated air AO from becoming enriched with alcohol vapor that is harmful to the behavior and health of the people present in the rooms. . The regulation module 17 can be a wet grid or a set of baffles making it possible to split the ozone into oxygen in order to prevent the evacuated air AO from becoming enriched with ozone harmful to the health of the people present in the rooms.

FIG. 3 is a semi-transparent schematic 3D view illustrating an embodiment of the inter-person interaction device 1 in the form of a sanitized air curtain gantry 20. FIG. 4 is a semi-transparent schematic front view of the sanitized air curtain gantry. FIG. 5 is a semi-transparent schematic side view of the sanitized air curtain gantry. FIG. 6 is a semi-transparent schematic top view of the aseptic air curtain gantry. FIG. 7 is a partial sectional view along AA visible in FIG. 4.

The aseptic air curtain gantry 20 comprises the frame 8 comprising two vertical posts 21A and 21B supporting, in the upper part, the air curtain diffusion module 6, in the lower part, the air curtain recovery module 10, and on each face, a first frame 22A on the front face and a second frame 22B on the rear face, the assembly defining the window 9. The vertical posts 21A, 21B respectively can be provided with feet 23A, 23B respectively.

The first frame 22A on the front face and the second frame 22B on the rear face have an extension such that they project laterally from the vertical posts 21A and 21B, above the air curtain diffusion module 6 and below the module air curtain recovery 10 to provide two side spaces 25C, respectively 25D, a space in the upper part 25B and a space in the lower part 25A. Each of the feet 23A, 23B respectively provides an opening 24A, 24B respectively such that the space in the lower part 25A leads to the side spaces 25C, 25D respectively. All the spaces 25A, 25B, 25C and 25D communicate with each other in order to allow the passage of the various pipes 7 and 15, if necessary. The space in the lower part 25A can be dimensioned to receive the main elements of the suction part AS and the evacuation part EV described in relation to FIG. 2. The legs can have fixing plates 51A, 51B respectively for anchoring to the ground or simply to raise a frame depending on the intended sitting or standing use. One or two shelves 50A, 50B respectively can be positioned under the windows 9, for example by being fixed on the frames 22A, 22B respectively (only visible in FIGS. 4 to 6). The shelves can be sized to ensure compliance with the minimum distance between people required by the standards in force. The presence of a tablet also depends on the intended use of the air curtain gate, for example a single tablet may be useful if the air curtain gate were to be added to a bank counter. The first frame 22A on the front face and the second frame 22B on the rear face also have the function of allowing tight coupling to the partition CL.

The air curtain diffusion module 6 comprises a box 28, coupling openings 26A and 26B to the inlet pipes 7 and a slotted diffuser 29. The box 28 is parallelepipedic in shape. The coupling openings 26A, 26B respectively are positioned on either side of the box 28 and open into the side spaces 25C, 25D respectively. The slotted diffuser 29 can be made in the form of a plate provided with several slots, for example slots of rectangular shape. The slots may have an adjustable width in order to adjust the thickness (i.e. the thickness in the horizontal plane) of the air curtain RI generated by the air curtain diffusion module 6 in the window 9.

FIG. 8 shows a way of producing an adjustable air curtain thickness RI by means of a conical diffuser 30 positioned directly under the slots 29. The conical diffuser 30 comprises two facing plates, each comprising a horizontal section 31 connected to an inclined section 32 connected to a vertical section 33. The distance between the two plates at the vertical sections 33 facing each other defines the thickness ERI of the air curtain RI. At least one of the plates can be provided in its horizontal section 31 with fastening means 34 to the slotted diffuser 29, for example via an assembly of the hole/bolt type. The holes can be oblong in the transverse direction relative to the width of the air curtain in order to be able to easily adjust the thickness ERI of the air curtain RI.

The air curtain recovery module 10 comprises a recovery opening 40, two inclined planes 41, 42 facing each other, a bottom 43 and coupling openings 27A and 27B to the exhaust pipes 15. recovery opening 40 is positioned at the bottom of the window 9. It advantageously extends over the entire depth of the gantry 20, that is to say over the entire depth of the frame 8 defined by the width of the vertical posts 21A and 21B . This opening is advantageously defined by the attachment in the high position of the two inclined planes 41, 42 respectively to the first frame 22A on the front face and respectively to the second frame 22B on the rear face. The two inclined planes 41, 42 facing each other meet in the low position or are fixed in the low position by means of the bottom 43. The inclined planes 41, 42 can for example be opened at an angle of the order of 20° to 40°, advantageously 30°. Thus, the configuration of this assembly forms a cone making it possible to recover the air curtain RI which tends to widen due to the loss of speed when it descends through the window and arriving at the opening of recovery 40. The coupling openings 27A, 27B respectively are positioned on either side at the level of the bottom 43 of the air curtain recovery module 10 and open into the side spaces 25C, respectively 25D.

Optionally, the recovery opening 40 or the volume defined between the recovery opening 40 and the bottom 43 can include a suction plate 44 (visible in FIG. 5). A suction plate 44 is particularly useful to generate an effective negative pressure at the level of the air curtain recovery module 10 when the parts of the building are in overpressure. This situation can be encountered, for example, in CBRN tents (i.e. nuclear, radiological, biological and chemical).

FIGS. 9 and 10 show examples making it possible to produce a suction plate 44. The suction plate 44 can be fixed by welding or be fixed in a removable manner in the recovery opening 40 between the inclined planes 41, 42.

FIG. 9 shows a first example. The suction plate 44 comprises a blade 45 of rectangular shape fitting into the recovery opening 40 to close it. This blade 45 is provided with a slot 46, for example of rectangular shape having a longitudinal extension substantially covering the length of the recovery opening 40 and of a width defined so as to create a controlled central depression in a depression zone 47 generated below blade 45.

FIG. 10 shows a second example. The suction plate 44 comprises two blades 48A and 48B, each rectangular in shape and assembled to form a V-shaped profile. The V-shaped profile is intended to fit into the recovery opening 40 to close it. Each blade 48A, 48B respectively is provided with several slots 49A, 49B respectively. These slots 49A, 49B are for example rectangular in shape having a longitudinal extension substantially covering the length of the recovery opening 40 and of a width defined so as to create a controlled central and lateral depression in the depression zone 47 generated below the two blades 48A and 48B.

By way of example, the aseptic air curtain gantry has a dimension (height, width, depth) of 1.90mx1.20mx0.40m, the window of 1.00mx0.90mx0.40m, the pipes and coupling openings have a diameter of 160mm. The air flow in the upper part is between 200 and 500m ³ /h, and in the lower part between 400 and 1000m ³ /h. The air curtain has a flow rate of between 200 and 500 m ³ /h with a speed of between 2 and 10 m/s for a curtain thickness of between 0.5 and 10 cm. The suction and depression motors can be duct ECM (electronically commutated motor) centrifugal fans with integrated silencer having circular connections with a diameter of 160mm, a maximum flow rate of around 600m ³ /h and a noise level of around 38dB at 3m. The dimensioning of the suction and depression motors in relation to the air curtain diffusion module and the air curtain recovery module makes it possible to generate an effective sanitized air curtain, i.e. capable of capturing bacteria, viruses, germs and insects/parasites while minimizing the power required and the noise emitted. In this way the operation of the sanitized air curtain gantry passes unnoticed, at the very least is not disturbing for the conversation between the people who interact.

The drawings and their description above illustrate rather than limit the invention. It should be noted that the embodiments of the present invention are suitable for fairly compact use, it is quite possible that the functional elements of the suction part AS and the evacuation part EV, in particular the motors and the disinfection modules are remote from the gantry, positioned in one of the rooms or outside the rooms given that these elements can be coupled by suitable pipes/ducts taking into account any pressure drops.
