Description

AUTONOMOUS PORTABLE UNIT FOR CLEANING, DISINFECTING AND ALSO UNDERSTANDING ALL TYPES OF OBJECT, COMPRISING A TEN INTEGRATING A STEAM GENERATOR AND A TANK

FROM SANITARY TO PROJECT

Field of the invention

The present invention relates to the field of cleaning, disinfecting and sanitizing all types of objects from a projection of steam or sanitizer.

It relates more particularly to the realization of an autonomous portable unit with a lance integrating within it a steam generator and a reservoir of sanitizer to be sprayed.

State of the art

There are multiple types of cleaning facilities, particularly in the field of motor vehicles.

In this area, some are fully automated, and include roller-brushes that clean the outer surface of vehicles. These installations are very popular because they require no effort for the user and are relatively fast. However, these brush-roller installations use drinking water drawn from public networks, this drinking water being additionally additive with the help of harmful products which pollutes it. As a result, these installations present an additional cost of investment and operation related to the treatment of this polluted water.

Other installations, called "self-service", leave the user free use of equipment made available to them. This material typically includes a high pressure water lance, to remove dirt from the outer surface of vehicles. The water can be mixed before the exit of the lance to a cleaning product to increase the cleaning efficiency.

Self-service facilities with high-pressure water hoses are less expensive than automated installations. However, they are not very economical in drinking water and electricity and are particularly polluting and require large amounts of water to wash a motor vehicle. In addition, they also require the use of additive products that cause pollution of the drinking water used for washing, which, as for brush-roller installations, indirectly increases their direct and indirect operating costs. pollution to fight when possible. Recently, self-service facilities equipped with steam-powered lances have been implemented. An example of this type of facility is being provided in Spain by OSVIC Maquinaria.

A steam cleaning facility has many interests. In particular, it is less expensive in investment than an automated installation and more water efficient than a facility operating with water under high pressure. In addition, water vapor can be used to clean both the inside and the outside of a vehicle. This is true provided that the water vapor used is adapted to the different media it has to treat.

However, with the production or application process currently the most efficient water vapor can induce residual moisture sometimes significant on and in the treated media, source of discomfort and slow but certain degradation of said media, new capture dust of all kinds, making the cleaning almost obsolete, at the same time accelerating the proliferation of organic bacteria (fungi). These fungi are themselves a source of allergy, with all the health consequences that result.

In addition, the proposed drying cycles are not only long, but above all leave traces on vehicles that involve the manual use of rags if one wishes to remove these traces.

In addition, the existing facilities also use drinking water from the public grid and electricity from the local distribution network.

To finalize the interior cleaning, some steam-powered installations include a separate suction system from the cleaning station with lance. This therefore forces the user to perform two separate operations at two different locations (two different stations) with two different types of hardware.

In addition, some of these steam-powered plants also take advantage of renewable energies by integrating an electricity generation system such as photovoltaic panels. But, it is noted that the installations carried out are notoriously insufficient to adequately and sufficiently supply cleaning needs, even for an individual intervening only on his own motor vehicle, mainly taking into account the power consumption.

However, the steam plants already in operation still have major drawbacks that can be listed as follows. First of all, these installations are just as energy-intensive as the well-known automated or "self-service" water-pressure installations, and they also consume drinking water from the public network.

In addition, like the pressurized water systems, they do not offer the possibility of drying the vehicle properly. Thus, in general, the user must drive the wet motor vehicle out of the facility for a period of time to allow the ambient air to dry the vehicle. This is harmful in particular because the wet vehicle can accumulate dust making at least partly obsolete cleaning performed or that natural drying may leave traces on the vehicle.

Furthermore, if, as mentioned, some of these installations offer a suction system separate from the cleaning station with lance, this is not very practical for the user who must at best change the cleaning utensil leaving his vehicle on the spot, at worst move it to bring it near the suction system.

Finally, the start-up of the boiler of a steam generator in these known installations requires a significant heating time and therefore a long waiting time for the user which can be a brake on the attractiveness of the cleaning facilities. "Self-service" steam.

Korean patent application KR 20090034133 discloses a steam cleaning car facility for cleaning both the interior and exterior of a vehicle by low pressure or high pressure steam spraying in accordance with the selection of a operator through a plurality of pressure switches. The low pressure proposed in this installation does not make it possible to obtain dry steam, which greatly humidifies the surface concerned and thereby a less cleaning efficiency.

Korean patent application KR 20100669923 discloses a steam vehicle cleaning installation supplied with water by a water bottle and supplied with electricity by a solar panel. This procedure and its characteristics are insufficient to adequately and sufficiently supply the cleaning needs, even for an individual operating only on his own motor vehicle.

These two patent applications have the same drawbacks as those presented above, even though the application KR 20100669923 proposes an attempt at autonomy in electrical energy that can only be very partial since it is dependent on weather conditions and limited in capacity due to the presence of a single solar panel. In addition, the use of a water bottle is unrealistic for a "self-service" use which must be dimensioned for a large number of daily vehicles and requires the implementation of a water pump. It can be specified that the quantity of a water bottle is itself insufficient to carry out the cleaning of a single vehicle, if only outside or inside, since this type of installation, with the system presented, consume, at least between 3 and 6 liters of water for a vehicle, depending on the use that is made.

Finally, all the devices that have been proposed to date do not deal with bacteria, whatever they are, ie with cockles, organic or chemical.

That is why the inventor of the present invention has proposed and claimed in the patent application FR 3034064 A1, a new vehicle cleaning installation that works in combination with a steam generation and a blowing or suction which allows efficient cleaning of both the interior and exterior of vehicles with a multitude of possible cleaning combinations.

The cleaning installation according to this application, however, requires the installation of steam generators in situ, which can have a significant cost of energy operation if the installation is intended to clean objects of smaller size than vehicles or objects by definition stationary and more generally any type of surface.

The inventor then judiciously proposed in the patent application FR FR3054457 A1 to integrate within a portable lance, a steam generator, which allows, while maintaining the characteristics and advantages of combined and simultaneous cleaning. according to the patent application FR 3034064 A1, to connect to any water network or rainwater tank, the blowing or the suction of air can be provided by a conventional device, and to ensure the effective cleaning of any object.

The inventor has now wished to go further in the autonomy to allow an individual to perform the cleaning of all types of objects regardless of the accessibility thereof, or with an in-situ connection to a local network water and / or electricity, or by avoiding any connection to a water network and an electricity network, for at least a period of time sufficient for a given number of cycles.

In addition, the inventor has studied the problems of disinfection and sanitation that could perfect the action of steam.

The object of the invention is to at least partially meet these needs for complete autonomy and improvement of the disinfecting effect and steam sanitation. Summary of the invention

Throughout the present application, the terms "inlet", "outlet" "downstream" and "upstream" are to be understood with reference to the direction of circulation of the fluids (water, steam, air, or air laden with dust, sanitizer ) in an autonomous installation incorporating a portable unit with portable module according to the invention.

Similarly, the terms "high", "low", "upper" and "lower" are to be considered by reference to an element horizontally.

The elements shown are not necessarily scaled.

The set of fluidic and electrical circuits integrated in the lance 2 is not necessarily described here.

FIG. 1 shows a portable unit 1 according to the invention comprising a cleaning lance 2, designed to carry out a cleaning both with steam and with the suction or with the blowing of air, and the disinfection and the sanitizing spray and a sheath 3 housing a central air suction / blow pipe 30 and a peripheral air blast pipe 31 and at least one power supply cable 32.

As illustrated schematically in FIG. 3, the peripheral pipe 31 and the electrical supply cable (s) are preferably in the form of a coil wound around the central pipe 30.

The lance 2 can operate according to several independent cycles as follows:

1 / aspiration alone;

2 / air blowing alone for drying purposes;

3 / vapor projection combined with simultaneous suction;

4 / sanitizer spray;

5 / vapor projection combined with simultaneous air blowing.

In practice, cycles 3 / and 4 / are rather dedicated to carry out a cleaning and sanitation and disinfection of the interior of a cabin, living room ..., while the cycle 5 / is rather dedicated outside, that is to say on surfaces in contact with the ambient environment.

The sheath 3 may advantageously consist of a flexible envelope and resistant to twisting, crushing and other attacks that may be caused during use. Typically, the sheath may have a length of the order of 2 meters. As shown in FIG. 2, the lance 2 is advantageously made up of three parts 4, 5 of which one is the body 4 housing a handle, the other the spout 5, and the last one a pivot connection 6 adapted to articulate the spout 5 with respect to the 4. This pivot connection 6 thus allows to incline at an angle of about ± 90 ° the spout 5 relative to the body 4, which allows to move the nozzle closer to the areas to be cleaned, sanitize and disinfect whatever their accessibility.

The rotation of the pivot 6 can be made by controlling an electromagnetic system with return springs. This rotation can be automatically blocked when a user presses the trigger 49 of a spear operating cycle.

In addition, there may be an angular indexing system between the spout 5 and body 4, which is visible from the outside.

As shown in FIG. 3, the handle 4 is traversed by a main duct 40 for blowing and air suction connected directly to the central end of the pipe 30.

The end of the handle 4 comprises respectively a fluid connector 41 for connecting to the peripheral air blast pipe 31, and an electrical connector 42 for connecting to the power supply cable 32.

A power supply cable 43 passes through the handle 4 in order to be able to electrically power the steam generator housed in the spout 5.

The handle 4 integrates a water reservoir 44 and supplies water to a water supply duct 45 for supplying water to the steam generator downstream in the spout 5.

A mass flow meter 46 with its microcontroller is also housed in the handle 4. The mass flow meter 46 is supplied with air by the air pipe 31 from the fluid connector.

Two air ducts 47, 48 are connected to the mass flow to supply air downstream respectively to the water atomization chamber 51 in the spout 5 as well as to the atomizer and sanitizer ejection nozzles 55.

Thus, the mass flow meter 46 has the function of very precisely controlling the amount of air flows sent into the ducts 47, 48 for the downstream atomization, in the spout 5, water or sanitizer. Advantageously, it is possible to provide instructions for flow rates of air and water which are of course the function of the operating cycle of the lance but also the position of the spout (horizontal, vertical, inclined ...). In other words, the microcontroller can control the mass flow taking into account the orientation of the spout in space, to maintain uniform application of steam or sanitizer regardless of gravity forces.

Finally, a trigger 49 for triggering the cycle previously selected by the user is pivotally mounted in the body 4.

The pivot 6 for articulating the spout 5 relative to the handle 4 is illustrated precisely in Figures 4 and 4A. It comprises a flexible coupling 60 housed between two main flanges 61, 62. The flexible coupling 60 makes it possible to ensure the sealed continuity of the main duct 40, ie through which the air flow is blown from the body 4 towards the spout 5 and vice versa.

As can be seen in FIG. 9A, the flange 61 is held at the spout 5 by means of fixing means 63. This flange 61 is also traversed by the air ducts 47, 48 as well as by the water supply duct 45. to fluidly feed the atomizing chamber and the steam generator 50 downstream and through the power supply cable 43 to electrically power the steam generator 50. In general, the pivot connection 6 allows while allowing any rotation from 0 to about 180 ° between the spout 5 and the body 4, to ensure the continuity of the flow of air for both the suction / blowing by the central ejection nozzle and for the atomization of the water and sanitizer, as well as the passage of the necessary connectivity to the steam generator.

To generate the projection of water vapor, a steam generator 50 is integrated in the top of the spout 5. This generator 50 receives upstream the atomized water droplets in a chamber upstream 51 by the air flow duct 45. The generator 50 thus delivers downstream the droplets of water vapor in the two ejection nozzles 52 which open laterally on the front and the top of the spout 5 (FIG. 5). Reference can be made to the international patent application WO2018 / 019472A1 filed by the same applicant as the present application.

To generate the sanitizer spray, a sanitizer reservoir 53 is integrated into the bottom of the spout 5. This sanitizer reservoir 53 diffuses by capillarity through a suitable valve 54 into two atomization and ejection nozzles 55 which receives upstream the air flow duct 48. Thus, under the effect of this air flow, the sanitizer supplied into the nozzles 55 will be atomized to be ejected to the outside. The valve 54 is electrically controlled for the diffusion of sanitizer.

The blower / air suction nozzle 56 is directly supplied by the central duct blowing or air suction 40. In the configuration shown, the nozzles atomizing and ejecting the sanitizer 55 are arranged on either side of the central nozzle 56.

As illustrated in FIG. 6, thermal insulators make it possible to isolate the steam generator 50 from the outside and also the sanitizer tank 53 with respect to the latter.

The electric cable 43 is used to supply firstly the steam generator 50 of the lance but also the microcontroller mass flowmeter 46 integrated in the handle 4 of the lance. It can also be provided that, according to a power line communication protocol (PLC) or a wireless protocol (Wifi, Bluetooth ...), the electrical cable exchanges information with the remote control unit in particular in the backpack of the portable unit.

In order to trigger the desired operating cycle of the lance, the portable unit comprises a man-machine interface connected to a control unit of the blower or suction device, as explained below. These air blowing or suction devices, preferably consisting of a turbine capable of operating in a reversible manner, are directly connected to the pipes of the sheath 3.

When it is desired that the portable unit 1 according to the invention can operate independently without any connection to a local water and electricity network and a centralized device for air blowing and suction, it is advantageous to connect it to a portable module 7.

As illustrated in FIGS. 10 to 13, this portable module 7 is advantageously configured as a backpack.

This backpack 7 comprises an outer shell 70 which can be flexible or rigid and which houses different compartments, straps 71 to be able to carry the backpack and advantageously casters 72 to move the backpack in rolling it on the ground. It is advantageous to provide the envelope with a security system to prevent any unwanted opening.

More specifically, within the envelope 70 a first compartment 73 houses an electric battery which is therefore the source of electrical energy of the portable unit.

A second compartment 74 houses a water reservoir which can supply the water reservoir 40 of the lance.

A third compartment 75 houses a waste collection tank (liquids, dusts, particles) which are sucked from the lance. A dust filter will be advantageously positioned in this third compartment so that all the particles and waste sucked are deposited in the tank provided for this purpose.

A fourth compartment 76 houses a sanitizer tank which can supply the sanitizer tank 53 of the lance.

A fifth compartment 77 houses at least one turbine that can operate in reversible mode as an air and suction blower device directly connected with the central nozzle 50 of the lance via the central duct 41.

Finally, a sixth compartment 78 houses the control unit for the electronic control of the various components.

Fluidic connectors 80, 81, 82 are mounted through the outer casing of the bag-to-back for the connection of the pipes of the sheath 3 respectively to the water tank, sanitizer and collection of waste by suction.

Also, an electrical outlet 83 through the outer casing 70 recharges the battery without having to take it out of the bag.

Finally, in order to ensure maximum comfort for the user, an air extraction 84 passes through the casing and a thermal insulation 85 is integrated into the outer casing 70.

For the sake of both comfort and automatic recharging, provision can be made to equip the portable unit 1 with a belt 9 which supports a case 90 of lance 5, as shown in FIG. 15. This case 90 is intended to receive the nozzle of the lance 5 out of use.

This case 90 may further incorporate a first quick fill valve connected to the water tank 74 through the water supply pipe. Thus, when the user has the lance 5 in the case 90, the control unit triggers the opening of this first fast filling valve and thereby a filling of the water tank 41 of the lance.

A second quick-fill valve can also be integrated in the case for the automatic filling of the reservoir of sanitizer 53 of the lance since that of the bag-to-back.

The belt 9 can also support an extension 91 for remotely holding the lance 5 for example for very high ceiling cleaning. This extension 91 is advantageously equipped with a handle provided with an on / off trigger, not shown, to initiate the operating cycles of the lance. This trigger on / off is therefore substituted where appropriate to that the handle of the lance.

An example of cleaning seats S steam A followed by a sanitizer spray cycle A is shown in Figure 14. The human-machine interface is advantageously a button box 10 fixed on the belt 9 of the user G, as shown in FIG. 15. Thus, depending on the operating cycle of the desired lance, the user presses on one or the other buttons 100.

It is clear from Figures 14 and 15 that the user can comfortably maneuver the portable unit 1 while having a complete autonomy in fluids and electrical energy.

It can be provided to have a stand-alone installation in a specialized center or in any public place in order to be able to recharge the fluids and electric energy backpacks.

As shown in FIG. 16, the autonomous installation can consist of a cabinet 11 incorporating a plurality of compartments 12 for storing portable units 1.

More specifically, the compartments 12 are each adapted to hook a backpack 7.1, 7.2 with a simultaneous connection to the fluid connectors 13, 14, 15 respectively of water, sanitizer and waste collected, as well as than an electrical outlet 16 for the electric charging of the battery backpack.

The cabinet is therefore provided with compartments 17, 18 which house both water and sanitizer containers of large volumes that can simultaneously supply several backpacks 7.1, 7.2,. collection tank of their waste and a large capacity electric battery for the electric charging of all the batteries of the bags.

It is advantageous to equip the cabinet with another control unit configured for the continuous measurement of the electric or respectively fluidic levels of the electric charging system and the water, waste storage and sanitizing compound tanks, as well as as usage times and in general, for recording and tracking any other information and data intended to optimize the use of the installation for each of its functions and for the various products related to its functions.

The invention which has just been described proposes a completely autonomous portable unit 1 which can be recharged with fluids and electricity both by means of a portable module on the scale of an individual and by means of an installation. autonomous at the scale of several individuals.

The portable unit allows any user to operate the lance according to either a suction cycle or air blowing, if necessary combined with a steam projection cycle, a sanitizer spray cycle . The invention is not limited to the examples which have just been described; it is possible in particular to combine with one another characteristics of the illustrated examples within non-illustrated variants.

Other variants and improvements may be envisaged without departing from the scope of the invention.

For example, if in the illustrated examples, the lance is provided with a spout which is articulated with a pivot connection on the body forming the handle, one can just as easily consider making a monobloc spool and therefore not articulated which can be of shape general right or with a determined angle between beak and body.

The spear can be made according to several possible arrangements of the outputs of the ejection nozzles:

- with an outlet in the same plane of water vapor, sanitizer, and air;

or with an outlet of the steam ejection nozzle set back relative to the outlet of the sanitizer and / or that of the air;

- Or with an outlet of the sanitizer ejection nozzle set back from the outlet of the steam and / or that of air.
