Description

Disinfection facility

The invention relates to a disinfection installation for supermarket baskets.

Prior art

The spread of viral diseases such as the flu occurs, in 80% of cases, by the hands. This is why, especially in an epidemic situation, it is recommended to wash your hands regularly, but also to disinfect objects through which viruses are likely to be transmitted, such as door handles or elevator buttons.

There is an ongoing need to further reduce the risk of spreading viruses.

The present invention aims to at least partially satisfy this need.

The invention proposes an installation for disinfection of a set of supermarket baskets, the installation comprising:
- A cabinet comprising an entrance for introducing the baskets into the cabinet and a closure member, for example a door or a shutter, intended to selectively close said entrance, preferably hermetically;
- a disinfection circuit comprising:
- a tank of disinfectant,
- a network of pipes equipped with nozzles and in fluid relation with the reservoir, at least one of said nozzles having an outlet orifice having a diameter of less than 0.2 mm,
- a circulator configured to extract disinfectant from the tank and bring it, through the network of pipes, to the nozzles, and
- a circulator control controller.

Advantageously, such a disinfection installation makes it possible, by nebulization of disinfectant product through the nozzles, to disinfect, at least partially, the baskets, and in particular the handles of the baskets which allow them to be carried and/or handled. The risk of contamination, especially through these handles, is thus considerably reduced, if not eliminated.

In addition, the controller allows disinfection without operator intervention. In particular, the disinfection can be carried out regularly during the day and/or at night, automatically.

Finally, disinfection is carried out simultaneously and with substantially the same efficiency for all the baskets and is therefore very fast.

The inventors have also made several major improvements to this installation.

According to a first main aspect of the invention, at least some of the nozzles can be fixed on a right side of the cabinet, and/or a left side of the cabinet, and/or a bottom of the cabinet, and /or a vault of the cabinet and/or the shutter member.

Advantageously, such an installation allows a homogeneous diffusion of a mist allowing effective disinfection of all the baskets.

Preferably, said at least part of the nozzles fixed to the closure member is connected to the rest of the pipe network by a flexible pipe.

Preferably, said at least part of the nozzles fixed to the shutter member is connected to the rest of the network of pipes only when the shutter member closes the entrance to the cabinet.

Alternatively or additionally, the installation may include a ventilation device, so as to ensure circulation, in the cabinet, of the mist emerging from said nozzles.

The spread of mist in the cabinet is then facilitated and better controlled.

According to a second main aspect of the invention, a nozzle, preferably each nozzle comprises a valve adapted to selectively open or close its outlet orifice depending on whether the pressure inside the pipe carrying said nozzle, i.e. i.e. upstream of the nozzle valve, is higher or lower, respectively, than an opening pressure. Preferably, the opening pressure is greater than 1.5 bar and preferably less than 5 bar.

Advantageously, between two disinfection operations, the pipe can be kept filled. Furthermore, at the end of a disinfection operation, no drops fall from the nozzles. Finally, the consumption of disinfectant product is reduced and the nebulization is more homogeneous, the sprayed mist being substantially the same throughout the disinfection operation.

According to a third main aspect of the invention, the installation comprises a rinsing device, and preferably a drying device.

The drying device may be the ventilation device.

Regardless of the main aspect considered, the installation may include a mist and/or rinsing liquid evacuation device. Such a device makes it possible in particular to evacuate the mist present in the cabinet before the cabinet is opened. In one embodiment, it makes it possible to evacuate liquids having accumulated in the cabinet during a disinfection operation, for example an accumulation of rinsing water.

Preferably, at least one nozzle has an outlet orifice having a diameter greater than 0.6 mm and, preferably less than 0.9 mm. Advantageously, this nozzle can spray droplets on the baskets. In one embodiment, the nozzle is oriented to spray a stream of droplets toward one or more basket handles.

A disinfection installation according to the invention may also include one or more of the following preferred and optional characteristics:

• the reservoir comprises a gauge for measuring the level of disinfectant liquid in the reservoir, said gauge being monitored by the controller, the controller preferably integrating a communication module suitable for transmitting, preferably by radio, information according to said level;

• the installation includes a battery supplying the controller and/or the circulator, or a power socket capable of being connected to the electrical network;
• the tank and/or the circulator and/or the controller are fixed outside the cabinet.

The invention also relates to a kit for disinfection of a set of supermarket baskets comprising:
- a disinfection installation according to the invention,
- A carriage configured to receive a plurality of baskets and to be housed in the cabinet.

Preferably, the carriage comprises several floors for receiving baskets, said floors being separated by perforated trays, the openings, in a tray representing more than 50% of the surface of the tray.

A disinfection kit according to the invention may also comprise one or more of the following preferred and optional characteristics:

• the carriage comprises several, preferably more than 2, more than 3 and/or less than 10 floors separated by trays;
• each plate has a width greater than 40 cm, preferably greater than 50 cm, preferably less than 100 cm, preferably approximately 60 cm;
• each plate has a length greater than 50 cm, preferably greater than 70 cm, preferably less than 200 cm, preferably approximately 96 cm;

detailed description

FIG. 1 represents an example of a disinfection installation 10 according to the invention. This installation comprises a cabinet 12 for receiving supermarket baskets and a disinfection circuit 14.

Cabinet 12 comprises a left side 20g, a right side 20d, a bottom 20f, a floor 20s and a vault 20v which delimit a substantially rectangular parallelepipedic enclosure. The cabinet 12 opens outward through an entrance 22 which faces the bottom 20f and which includes an obstruction member 20p, preferably a door or a shutter, allowing the cabinet to define a hermetically sealed enclosure. .

Preferably, the enclosure of the cabinet 12 opens outwards substantially only through the entrance 22, when the obstruction member 20p is in the open position. The obstruction member 20p is, in the example of FIG. 1, a door. Alternatively, as shown in Figure 5, the shutter member can be a shutter, preferably an electric shutter.

The enclosure is adapted to receive more than 8 baskets, preferably more than 10, preferably more than 20 baskets, preferably more than 30 baskets. In one embodiment, it delimits locations for this purpose.

In a preferred embodiment of the invention, the enclosure is adapted so that the cabinet receives a trolley 18 from a kit according to the invention, preferably more than 1, preferably more than 2 and/or less than 5, less than 4 carts 18.

Preferably, the 20s floor of the cabinet, which faces the 20v vault, has a retention basin, preferably at least 3 cm high (not shown). The floor of the cabinet can in particular comprise a grid configured to resist the weight of the trolley and the baskets as shown in figure 5.

The locations 18e for the baskets 13 are then defined by the carriage(s) 18 as shown in Figure 2.

The use of a cart facilitates the introduction and removal of baskets from the disinfection installation.

Preferably, each trolley is designed to be handled by a single person. The carriage may in particular comprise wheels. In one embodiment, the enclosure is partitioned according to the number of carriages. Each carriage can thus be rolled into a respective housing. The partitions, vertical, are preferably perforated, preferably mesh. Preferably, the holes, or "openings", in a partition represent more than 50%, more than 70%, more than 80%, preferably more than 90% of the surface of said partition. Fog circulation is improved.

Preferably, the carriages are substantially identical. Only one carriage is therefore described below.

A trolley has one or more rows, one or more columns and one or more floors, in the direction of width, depth and height, respectively. In the example of Figure 1, the carriage 18 has two rows, five floors, and three columns, thus delimiting 30 slots 18e.

The rows and columns are preferably separated vertically by 18p walls, preferably wire mesh ("verticality", "height" and "horizontality" refer to a situation in which the cabinet, trolley and baskets are placed on flat horizontal ground, in a service position). The 18p walls can be metal or plastic. Preferably, the walls consist of a grid or one or more bars. Such vertical walls advantageously allow the horizontal circulation of the mist between the baskets of the same floor.

Preferably, a carriage has more than 3, more than 5 and/or less than 20, or less than 15 or less than 10 floors. Preferably, each stage comprises more than 1, more than 2, more than 3, and/or less than 20, or less than 15, less than 10, less than 6 slots.

The heights of the floors can be the same or different. For example, the trolley can have two floor heights h1 and h2, for example between 30 cm and 40 cm, and between 40 cm and 50 cm, respectively. Preferably again, the height of a floor is modifiable, which makes it possible to modify the number of floors, and to adjust them to the dimensions of the baskets.

The floors are separated from each other by 18n trays. Each tray is configured so that the baskets can be placed on it.

A tray can be formed by a grating or by a set of at least two bars which preferably extend parallel to one another, horizontally. The meshes of the mesh preferably have a surface greater than 1 cm ² and/or less than 100 cm ² , preferably less than 50 cm ² . Preferably, the holes, or "openings", in a plate represent more than 50%, more than 70%, more than 80%, preferably more than 90% of the surface of the plate. The circulation of fog and the evacuation of liquids are improved.

The tray may in particular be metallic or plastic. The trays are preferably removable. For example, the carriage may comprise rails 80, the trays being able to be slid on these rails, as shown in FIG. 6. Preferably, the number of pairs of rails is greater than the number of trays, so that the height h d a floor can be easily changed.

The trays can have a width L ₂₃ greater than 40 cm, preferably greater than 50 cm, more preferably equal to 60 cm. The trays can have a length L ₂₂ greater than 50 cm, preferably greater than 70 cm, preferably equal to 96 cm.

In a particular embodiment, a trolley may comprise two shelves spaced apart by a height h of 36 cm and/or two shelves spaced apart by a height h of 45 cm. Each tray can have a length L ₂₂ of 96 cm and a width L ₂₃ of 60 cm, such a tray being advantageously configured to carry more than 8 baskets.

For example, for a trolley 18 having a height L ₂₁ of 180 cm, 3 shelves 45 cm apart can be fixed on the trolley, or 4 shelves 36 cm apart can be fixed on the trolley. The height h separating two trays can vary on the same carriage.

Each slot is preferably configured to accommodate a respective basket 13, preferably a single basket, as illustrated in Figure 2. Preferably, the slots each have a length l' greater than 50 cm and/or a width l greater than 40 cm. cm and/or a height h greater than 50 cm. Preferably, each location has a width greater than 50 cm and a length greater than 40 cm.

A basket preferably has a capacity greater than 5 L and/or less than 30 L. It is preferably made of plastic or steel. Preferably, each basket has handles.

A basket may include wheels and a pulling handle, preferably retractable.

The baskets are preferably nestable one inside the other in order to limit their size in the supermarket. To promote the circulation of mist, however, it is preferable to limit contact between the baskets inside the enclosure of the cabinet, and therefore to avoid fitting them into each other. In one embodiment, the baskets are not nestable into each other or, preferably, the slots are configured to receive only a single basket. In other words, any pair of two nested baskets cannot be introduced into the disinfection cabinet.

To promote the circulation of the mist, the walls of the baskets are preferably perforated, preferably mesh. Preferably, the holes, or "openings", in a side wall and/or in the bottom of the basket represent more than 50%, more than 70%, more than 80%, preferably more than 90% of the surface of said side wall and/or said bottom.

The disinfection circuit 14, illustrated in detail in Figure 3, comprises a tank 30 containing a disinfectant 32, a circulator 34, a network of pipes 36 carrying nozzles 38, and a controller 40 for controlling the circulator 34.

The tank 30, the circulator 34 and the controller 40 are preferably arranged in a housing 42.

As shown in Figure 4, box 42 is preferably located outside cabinet 12.

The user can then more easily access the box. Such a positioning of the housing 42 advantageously allows access to the reservoir, facilitating the replenishment of disinfectant product when necessary.

The box 42 can be fixed on the bottom wall 20f. Alternatively, the housing is attached to the left side 20g or the right side 20d.

The tank 30 can be for example made of plastic, for example polyethylene. Its capacity is preferably greater than 0.5 l, preferably greater than 1 l, preferably greater than 2 l and/or less than 50 l, preferably less than 20 l, preferably less than 10 l.

The disinfectant product 32 is preferably approved for food contact. In one embodiment, in particular when the disinfection installation is placed outside and used in winter, the disinfectant product preferably contains alcohol, preferably more than 3% alcohol.

The circulator 34 is preferably a pump whose inlet 43 is in fluid communication, via a tube 44, with an outlet 46 of the tank 30, and whose outlet 48 is connected to the pipe network 36. The circulator 34 may in particular be a diaphragm pump.

The circulator 34 can operate under a direct voltage of 12 V. It can also, preferably, operate under an alternating voltage, for example 220 V.

Alternatively, circulator 34 may be a pressure source, such as a compressed air cylinder, selectively in fluid communication with the interior of reservoir 30 through a regulator controlled by controller 40.

The power of the circulator 34 is adapted to the pipe network, preferably so as to be able to impose, in the pipes, a pressure greater than 1.5 bar and/or less than 5 bar.

In a preferred embodiment, the installation comprises a power supply configured to supply electricity to the electrical consumers, and in particular the circulator 34 and the controller 40.

Preferably, the power supply includes an electrical outlet intended to be connected to the mains, not shown.

The installation may additionally comprise a battery 49 to which electrical consumers operating in direct current are electrically connected.

The network of pipes 36 preferably comprises a manifold 50 and ramps 58. An inlet 52 of the manifold 50 is in fluid relation with an outlet 48 of the circulator and the outlets of the manifold 50 are each connected to a proximal end 54 d a respective ramp 58, the other end 60 of the ramp, or “distal end” being plugged.

The number of ramps 58 on the 20v vault can be identical to the number of rows of baskets that the cabinet can accommodate. The number of ramps on the vault preferably depends on the number of rows per trolley 18 and/or the number of trolleys 18 that the cabinet 12 can receive. Each ramp 58 on the vault preferably extends above a respective row of baskets, preferably in a median vertical plane of the row of baskets, that is to say extends above the plane median longitudinal of each basket. The distribution of the disinfectant 32 is more homogeneous.

The ramps 58 on the vault 20v are preferably straight and preferably extend parallel to each other, preferably in a common plane, preferably horizontal.

The length of a ramp 58 on the vault 20v, preferably of each ramp 58 on the vault 20v, is preferably greater than 50%, preferably greater than 70%, preferably greater than 90% of the length L ₁₂ of cabinet 12.

Preferably, ramps 58 are attached to the left side 20g. The number of ramps 58 on the left side 20g can be the same as the number of baskets the cabinet can accommodate deep. The number of ramps on the left side 20g preferably depends on the number of slots per floor and per row of trolleys 18 that cabinet 12 can receive, that is to say the number of columns of the trolley. Each ramp 58 on the left side 20g preferably extends opposite each of the columns. The distribution of the disinfectant 32 is more homogeneous.

The length of a ramp 58 on the left side 20g, preferably of each ramp 58 on the left side 20g, is preferably greater than 50%, preferably greater than 70%, preferably greater than 90% of the length L _{1 1} of cabinet 12.

Preferably, ramps 58 are attached to the right side 20d. The number of ramps 58 on the right side 20d can be identical to the number of baskets that the cabinet can receive in depth. The number of ramps on the right side 20d preferably depends on the number of slots per floor and per row of trolleys 18 that the cabinet 12 can receive, that is to say the number of columns of the trolley. Each ramp 58 on the right side 20d preferably extends opposite each of the columns. The distribution of the disinfectant 32 is more homogeneous.

The length of a ramp 58 on the right side 20d, preferably of each ramp 58 on the right side 20d, is preferably greater than 50%, preferably greater than 70%, preferably greater than 90% of the length L _{1 1} of cabinet 12.

At least one ramp 58 can be attached to the obstruction member 20p. Said ramp on the obstruction member can be connected to the rest of the network of nozzles 14 only when the obstruction member 20p is in the closed position. Alternatively, said ramp on the obstruction member 20p is preferably connected to the rest of the network of nozzles 14 by means of a flexible pipe.

An example of an installation comprising ramps 58 on the left side 20g and the right side 20d is represented in figure 5.

In one embodiment, ramps 58 can be attached to the partition walls.

Two adjacent ramps 58 are preferably separated from each other by a distance d greater than 40 cm and/or less than 1.20 m. Preferably, the distance between two adjacent ramps is the same regardless of the pair of two adjacent ramps considered.

Each ramp carries a plurality of nozzles 38, preferably regularly spaced. The distance between two successive nozzles, along a ramp 58, is preferably greater than 30 cm and/or less than 1.20 m.

A nozzle 38, preferably each nozzle 38 has an outlet orifice whose diameter is less than 0.2 mm.

Spraying through such nozzles forms a mist inside the cabinet. Advantageously, such a mist makes it possible to disinfect the entire surface of the baskets.

Preferably, each nozzle 38 also comprises a valve which opens under the effect of a pressure, in the network of pipes 58, greater than a predetermined opening pressure.

The controller 40 is preferably an automaton programmed to control the circulator 34 according to a predetermined cycle, preferably so that the circulator is active for a duration greater than five seconds and/or less than 20 seconds.

Preferably again, the tank 30 comprises a level gauge monitored by the controller 40 and the latter incorporates a communication module suitable for transmitting corresponding information to an operator, in particular in the event of an insufficient level.

The operation of a disinfection installation according to the invention follows directly from the preceding description.

When a basket is considered potentially contaminated, i.e. it has been handled by a consumer while shopping, it is collected and preferably placed on a trolley. Preferably, it is arranged so as not to be in contact with the other baskets.

Trolley 18 is then introduced into the enclosure of cabinet 12.

After closing the obstruction member, the controller 40 can be activated manually or by a clock.

In one embodiment, the controller 40 first commands the closing of the shutter member of the entrance 22 of the cabinet, preferably a shutter or a door, or an operator manually closes this shutter member . The baskets are then well insulated from the outside, which allows particularly homogeneous spraying.

Preferably, when the disinfection operation is started, the controller blocks the opening of the obstruction member and unblocks it when the disinfection operation is finished.

Controller 40 then controls circulator 34 to perform a disinfection operation. Powered by the battery 49 or the mains supply, the circulator 34 then extracts disinfectant product from the reservoir 30 and injects it into the network of pipes 36. The action of the circulator 34 makes it possible to increase the pressure inside ramps 58 beyond the opening pressure, which causes the opening of the valves of the nozzles 38. Each nozzle 38 then projects a mist, in the direction of the baskets. The valve advantageously allows regulation of the nebulization pressure, and therefore homogeneity of the microdroplets of the sprayed mist.

The arrangement of the nozzles and the ramps advantageously allows a projection on all the baskets present in the cabinet.

In one embodiment, one or more fans 72, may be arranged in the cabinet to disperse mist and/or dry the interior of the cabinet.

A luminous warning device, for example in the form of a flashing light, can be controlled by the controller 40 in order to warn that a disinfection operation is in progress.

The disinfection operation preferably lasts less than one minute, preferably less than 30 seconds, preferably less than 20 seconds.

At the end of the operation, the controller 40 controls the stopping of the circulator 34. The pressure in the ramps 58 decreases, which leads to the closure of the nozzle valves. The ramps 58 however remain filled with disinfectant, which makes it possible, during the following disinfection operation, to guarantee immediate spraying in the form of a predetermined mist.

In another embodiment, the disinfection operation comprises a step of rinsing the baskets, in order to eliminate any traces of product present on the baskets.

Water can be sprayed through nozzles 58, preferably having an outlet orifice whose diameter is greater than 0.6 mm.

In the example of Figure 5, the grate placed on the floor 20s notably makes it possible to recover the water and/or the disinfectant in a retention tank (not shown here), located under the grate.

A drying step can optionally be carried out after spraying the disinfectant product and/or after the rinsing step. A ventilation device 72 can be used.

Preferably, the controller regularly checks the filling level of the tank 30 and, if necessary, sends an alert message to an operator. The latter can thus maintain a minimum level of disinfectant liquid in the tank 30.

An alert message can be issued in the event of a technical problem, for example to indicate that the obstruction device is not closed hermetically, or to indicate abnormal pressure in a ramp.

As is now clear, the invention provides an effective and rapid solution to limit the spread of viruses.

Of course, the invention is not limited to the embodiments described and represented, provided by way of illustration only.

In particular, the number of ramps and their positioning can be modified.

"Behave" or "understand" or "present" must be interpreted in a non-limiting manner.
