Definitions
- Such devices generally proceed by spraying coarse water under high pressure, and its recovery is carried out by a low air flow of 25 to 40 liters per minute subjected to a depression of -1800 to -2500 mm of water column only, one and the other of these working conditions does not allow support hygiene, or even deep cleaning.
- Such devices are also particularly ill-suited not only when it comes to hygiene but even when cleaning textiles woven or non-woven (on floors, walls or furniture), the drying of which is not obtained in 24 hours and sometimes more.
- the spraying device associated with it and which is external to the air intake duct not being itself contained in a particular conduit beyond the outlet of the spray which thereby is done in the open air.
- German document G9105512.1 describing a cleaning device comprising a water tank with a heating device, a pump for transporting water to a supply hose and a dirty water collection tank to which a vacuum pump is connected and from which having a suction pipe: the supply pipe and the suction hose lead to a rigid cleaning head provided exclusively for cleaning textiles on the floor; plasters, terracotta, thermoplastic, plasters cannot be cleaned; and all cleaning device organs are controlled by microprocessors and a control panel from which the operator may direct operations.
- This process makes it possible to work in class 10 premises, that is to say which admit no more than 10 polluting particles of 0.3 micron per foot 3 , said device not rejecting any germ into the air nor particle.
- the process does not leave on the surface treated with maximum 10 CFU of bacteria per 25 cm 2 and even as the case less than 2 CFU per 25 cm 2 , and reduces the germs, bacteria, microorganisms contained in and on the pores of the support by a rate of 10 5 by participating in the elimination of Biofilm (gangue from 1 to 10 microns thick permanently bonded to the support), with a visual cleanliness index of 0 in the Bacharach scale, the definition of which is recalled at the end of this description.
- the apparatus or device according to the present invention can also, because of its very strong suction the implementation of a surface cleaning process, as indicated previously, by high pressure fog, bringing the pressure micronization of water at around 150 to 200 bar, on vertical walls or horizontal, the power of the suction and the tightness of the terminal relative to the treated surface, always preventing the occurrence of flows of water outside its periphery; the water temperature can be range up to 60 degrees C and then allows in this case for some supports to effectively clean and / or even strip all surfaces, as some existing devices could in some cases this day, but with better efficiency without pouring water and products.
- the device is essentially characterized by a set of means allowing the micronization of water at a flow rate and at variable temperatures, associated with means producing simultaneously a very strong air intake, adjustable in depression and flow, said means being simultaneously controlled by at least one means central electronics such as a microcomputer which provides through a software package regulating the water and air flow rates, the all according to a choice determined manually by the operator in depending on the nature of the material to be cleaned, and the nature and the importance of its pollution.
- a significant number of automatic programs to process all media such at least 36 settings such as: ceilings, walls, floors, furnishings, etc, whatever the nature of their material such as wood of all species, jute, textiles, plaster, marble, thermoplastics, terracotta, stucco, etc ... all the parameters being preset for each of these cases thanks to said central electronic means of the following device the invention, taking into account the fragility of the support and the rate hygiene required, even up to 80 m horizontal distance and 30 m vertical distance.
- the hygienic device in addition to the elements mentioned above, some of which are known to the apparatuses according to the invention, comprises a means of humidifying the surface of the object to be cleaned in the form of a very fine nebulization, emitted by at least one micronization nozzle nearby from said surface, water taken from a water storage tank clean, said micronization nozzle being integrated into a device terminal located at the end of a windsock, preferably flexible, suction.
- the invention is further characterized by the details which will emerge from the description which will be given thereof.
- Figure 1 is a schematic view showing the different elements of the device.
- Figure 2 is a schematic vertical sectional view of the chamber containing the organs ensuring the suction of air, associated with the chamber receiving the polluted water after cleaning the treated surface.
- Figure 3 is a schematic plan view of the keyboard for automatic process management, including the screen displaying the status of the programmed functions.
- Figure 4 is a schematic view of the device which allows two employees working at the same time using the same device central in the same room or in two different rooms.
- FIG. 5 is a partially cutaway schematic view, given at for example, a terminal located at the end of the windsock, and which contains the micronization organ.
- the device comprises the tray 1 containing the water clean for micronization and tank 2 receiving the recovered water by suction loaded with polluting elements.
- Each of these bins itself includes a probe 3 noting the fullness of the tank correspondent and a probe 4 noting its empty state.
- Said probes 4 and 3 of the clean water tank 1 control coordinated way the electrostatic valve 5 which authorizes or stops, according to the order received, filling said reservoir with clean water 1.
- the supply of clean water connected to the network is controlled by the central computer if the clean water tank is empty; the probe high level stops and closes the water inlet solenoid valve.
- Probes 3 and 4 of tank 2 for recovering polluted water also controls in a coordinated manner the motor pump 6 which authorizes or stops emptying said container when it is connected to a pipe outdoor evacuation.
- the micronization of the clean water contained in tank 1 is obtained by pressurization by means of the pump electric 10 which routes it through piping 12 to the organ 11 of micronization placed near the end of the windsock suction hose 7.
- the clean water thus propelled by the electric pump 10 can be brought to variable temperatures always lower than the temperature critical supported by the material to be hygienic.
- the device is completed by the valve 18 which controls the arrival pressurized water to the micronizing member there; by the valve discharge 19, which opens more or less depending on the pressure prevailing in the conduit 12 according to the closed state of the valve 18, allows excess pressurized water to be returned to tank 1; speak thermostat 20 which regulates the heating intensity of the heating body 15; by motorized solenoid valve 21 which, depending on a setpoint programmed, more or less communicates the tray 2 with the atmosphere to settle the depression which reigns there; through the hatch motorized 22 which, also according to a programmed setpoint, regulates the air flow sucked by the more or less important obturation of the opening 23 of the trunk 26 which makes the tray 2 communicate with the first of the turbines 8.
- Said opening 23 is protected by the deflector 51 which avoids the suction by the turbines 8 of the particles conveyed by the polluted air introduced into the tank 2 from the suction sleeve 7, thus that the suction of the condensation that can occur in this same bac.
- the drive members consisting of the motors 9 which drive the turbines 8 are contained in the enclosure 24 which contributes by itself to the soundproofing in which the muffler 27 placed on the pipe 28 through which the air sucked in the turbine 8 is discharged into the atmosphere.
- Said turbine 8 receives the air which it sucks through the trunk 26 whose opening is located in tray 2.
- the tubing 28 comprises the Venturi 29 conical nozzle designed to draw in ventilation air from the motors 9 in order to contribute to their cooling as well as to reject outside the room being cleaned, through the tubing 28 which can have a very long length, polluting particles of all natures which can be emitted by the engines 9 themselves during of their operation.
- the tank 2 meanwhile, in addition to the probes 3 and 4, includes a probe emergency 30 intended to avoid, in the event of failure of the high probe 3, that the polluted water recovered, or the foam which can float, does not rise until the opening 23 of the suction tube 26 of the turbines.
- the computer by means of a small electric pump the latter to take 25 to 50 ml in an anti-foam container 55 necessary and thus reduces the foam in the liquid state.
- This same opening 23 of this suction tube 26 is capped with a cap 52 to avoid the direct introduction of water into this conduit 26 during the wash tank 2, its cover removed.
- the disinfectant is renewed every time filling with clean water after the drain pump to empty the tank dirty water.
- the antifoam is then renewed in the dirty water tank automatically.
- These are the sensors, high level of the water tank dirty and low level of clean water tank, which inform the computer for opening the electro-pumps supplying the products disinfectants and defoamers, if requested beforehand for the hygiene of the ceiling, wall, floor support, furnishing etc.
- Tray 2 also includes a container of general shape cylindrical micro-perforated 31 which is removably attached to the tube air intake 7, and which receives polluted water through it recovered and the air simultaneously sucked.
- Said container 31 constitutes a filter which retains the solid particles contained in the dirty water, which only crosses it and fills tray 2.
- the device thus constituted makes it possible to carry out the setting in surface hygiene by simultaneously operating the motor 10 for pressurizing the clean water contained in the tank 1 and the motors 9 to empty the tank 2 by means of the turbines 8.
- the vacuum and the flow rate of the aspirated air are automatically and individually controlled by solenoid valve 21 and the motorized hatch 22 and a motor speed variator 9.
- the flow of miconized water may vary from 0 to 70 liters per hour by the clearance of the valve 18 closing; and through the game of hatch 22 the flow rate of the sucked air can itself vary up to 100 liters per second under a static depression which can go up to -5000 or -6500 mm of column or 65 KPa of water approximately by the play of the valve 21.
- the temperature of the micronized water will itself be variable being preheated in the coils 13 which externally envelop the engines 9 of the turbines 8 where they recover the calories produced by their functioning, thereby ensuring their cooling and economic recovery of energy which, without this provision, would be dissipated in pure loss inside the enclosure 24.
- a disinfectant product, of the type hydrogen peroxide contained in an annex 44 tank can be diluted in the water in tank 1, under the control of the solenoid valve 45 piloted by computer, the same for defoaming.
- each of these adjustments could be made manually by a direct action on each of the above-mentioned control bodies. But they are more advantageously carried out by means of one or more microprocessors which act as microcomputers and control continuously each of the functions according to the instructions manually chosen by the operator for the desired result and displayed on the liquid crystal screen 37 that the device includes; this screen can display: the type of supports to put hygiene, if we add disinfectant and / or antifoam, the type of terminal depending on the number of micronization nozzles (always in relation to the type of support to be treated), the maintenance connection, also the diagnosis of possible faults, and the hourly counting of the operating time for the review, as well as the display of the material safety data sheet the device (type, serial number, version etc ...) ....
- All functions can thus be automatically determined by a microprocessor based on the choice set by the operator, this program automatically setting the parameters (pressure, temperature, flow of micronized water; vacuum, flow air intake) corresponding to the best criteria for hygiene of the different surfaces to be treated: ceilings, floors, walls, etc. and depending on their nature: stone, plaster, wood, plastic fabrics, glass, marble...
- the necessary commands are performed from a keyboard 38 (fig. 3) which has two keys 39 and 40 allowing the incrementation and decrement the programs stored in memories, and two + and - keys (41 and 42) to increase or decrease the intensity of each of the values automatically entered by the program (pressure, flow, vacuum, temperature) and a key "Enter” 43 validating the chosen program as well as each of the values corresponding to the different operating parameters.
- a key can cancel any current action or program and a specific light, of the "led” type, red illuminating a button in triangle with an exclamation mark can warn of a defect you have to go look for it to visualize it and know nature in order to correct it.
- Screen 37 informs at all times of the status of the operation.
- Each of the above functions can also be ordered or modified by the keyboard, under the control of the microcomputer which can oppose outliers.
- Automaticity is pushed to ensure automatically, when the appliance is connected to inlet and outlet pipes of water, draining the recovery water with an electric pump 6 operating under the control of probes 3 and 4 of tank 2.
- venturi device 29 which contributes to the cooling of the motors 9, energy saving being obtained by recovering calories naturally produced by the engines 9 of the turbines 8 during their operation thanks to the coils 12 which surround the turbines and in which clean water circulates as soon as it leaves tank 1.
- the tube flexible 7 which conducts the sucked air, and which carries at its end the organ 11 micronization may be of sufficient length to that we can work inside a room, the device itself remaining outside the building.
- the tube outlet placed at the outlet 54 of the turbines 8 (FIG. 1).
- the device may include two micronization-suction equipment represented by the tubes 7 A and 7 B of FIG. 4 each associated with a separate tube of clean water and each carrying a terminal.
- the device may include two micronization-suction equipment represented by the tubes 7 A and 7 B of FIG. 4 each associated with a separate tube of clean water and each carrying a terminal.
- any of these two pieces of equipment can be put into service by the mere fact that its micronization-suction terminal which is at its end is brought into contact with a surface to be treated .
- each of the tubes 7 A and 7 B is provided at its downstream end situated inside the tank 2 with a motorized valve 33 A or 33 B controlled by a pressure sensor 32 A or 32 B which simultaneously controls a 34 A or 34 B solenoid valve capable of opening or closing the branch circuit 35 A or 35 B which bypasses the corresponding turbine 8 between its evacuation tube 54 and the suction tube 7 A or 7 B .
- the pressure prevailing inside is close to atmospheric pressure.
- the sensor 32 A immediately controls the closing of the motorized valve 33 A and simultaneously causes the opening of the solenoid valve 34 A which recycles the discharge air towards the tube 7 A in a sufficiently small quantity so as not to significantly increase the pressure therein. reigns close to atmospheric pressure, which keeps the valve 33 A closed, isolating this tube 7 A which therefore does not participate in the action of the device.
- each sensor 32 which controls the solenoid valve associated 34 also controls solenoid valve 18 which is on the circuit micronization water, so that the automaticity of the setting operation in hygiene is complete, each windsock 7 comprising associated with it has a tube 47 for transporting clean water.
- Terminal 46 which adjoin the terminal windsock 7 and the water inlet tube 47 which itself carries the micronization nozzle 11 is maintained, by the sole effect of the vacuum prevailing in the air duct 7, in contact with the surface to put in hygiene.
- the micronization member 11 is located at a certain distance but close to the surface to be cleaned.
- the terminal 46 is also characterized by the fact that the tube 47 which leads pressurized water to the micronizing member 11 and the air duct 7 are parallel and adjoining inside said terminal 46.
- Said tube 47 which carries the organ 11 for micronizing the water near the end of the terminal 46 continues beyond said member 11 and is continues without interruption or opening of its wall in zone 53 located beyond this organ to its own end which is in the same plane as that of the air duct 7 together forming a same double ducted mouth which ensures, when in contact with the surface to be cleaned, perfect sealing of said terminal by report to the outside, which prevents any untimely sagging out of said terminal. It can also wear a peripheral lip at its base flexible elastic 48 which, projecting from the lower edge of the mouth of said terminal, ensures this same seal on surfaces that do not do not have perfect flatness.
- Said brush 50 may be cylindrical (not shown) with movement fast and continuous rotation in the horizontal plane to satisfy the most difficult hygienic conditions.
- said terminal can also be provided with rollers so to keep its height constant with respect to the treated surface, the elastic peripheral lip maintaining the seal described above.
- Such a terminal retaining its same general characteristics, can marry an external configuration which allows it to facilitate its manipulation according to all the configurations of the object to be implemented hygiene.
- This is how the periphery of his mouth can present very diverse shapes and dimensions, ranging from, for example only, from about 4 cm to about 40 cm, its shape in this case being oblong. It can also be placed at the end of an extension telescopic to reach surfaces in high situations.
- this device ensures a considerable time savings in commissioning, which consists in the sole choice by the operator of the program corresponding to the nature of the surface to be treated, the integrated microcomputer ensuring determination of the various corresponding parameters, as well as the maintaining their consistency during the operation.
- the start-up thus simplified can be preceded in some cases by the establishment manual detergent on the surface to be treated.
- the visual cleanliness level controls allowed to obtain the index 0 on the Bacharach scale: such control being made by passing a wadding on the support whatever it is and that we want to control, after cleaning, and on a surface of 30 cm by 30 cm from which 8 samples are taken; then we compare the wadding with which we made the so-called 8 samples on a scale of colors from white to black, knowing that the interprofessional standard of cleaning sets an index of 3 to define a very clean floor and 5 for the textile.
