FR2921571A1 - Colored foam obtaining device for washing automobile, has system mixing hyper concentrated and colored shampoo with water and automaton opening valve by relay system when request for foam is activated by control to distribute mixture - Google Patents

Abstract

The device has a system for mixing hyper concentrated and colored shampoo with water in one of yellow, red and blue mixing containers (28, 37, 38). An automaton (9) opens a solenoid valve (27) by a relay system (10) when a request for foam is activated by a control (8) to distribute the mixture from the container based on programmed timing. The colored mixture is conveyed towards a pump (11) that ejects the mixture towards a collector via solenoid valves (12, 13), where the mixture is emulsified by compressed air via solenoid valves (14, 17) and directed towards brush outlets (16, 15).

Description

The present invention relates to a device for obtaining foam of different colors for car wash and distributed on the vehicle by means of a brush connected to this device by a flexible plastic hose.

The foam flowing at the level of the brush in cords separated ik colors 5 distinct yellow blue red, without mixing. each flow of colored foam remaining well marked and spreading by napfes of successive colors, corn always separated and cyclically.

The foams used in the car wash, traditionally and until now, were mostly white, or single-color, mostly inconsistent, liquid and unformed and, therefore, unpleasant in use.

The device according to the invention overcomes these disadvantages, this machine producing a foam formed, thick, unctuous and spreading at a frequency of successive and alternating colors, always very not mixing mixing them (yellow, blue, muge).

_15 .. The quality of foam obtained and the play of colors make Inès approved the use of this process to brush the Ehide.

According to the particular embodiment of this nhine constituting the device, main systems appear in its design.

- A system intended for. prepare the ingredients to obtain a 2.0 mixture to be emulsified by adding compressed air. This mixture is * imposed with a hyper concentrated shampoo of color, either red, or yellow, or blue, and water_

- A sysenne power supply and a management automaton,

A system for dispensing the mixture after emulsion to the washing tracks 2.5 (the model presented here has two outlets for two brushes, thus wall two car wash tracks. -The attached drawings illustrate 'cation

- Figure t represents the general diagram of the machine showing the three different systems.

FIG. 2 shows the brush that diffuses the foam when used on the vehicles.

- Figure 3 shows the machine as a whole, on its stainless steel frame.

With reference to these drawings, the first system, that intended to prepare the ingredients, comprises a water inlet with a quarter-turn valve (i). This water coming hard at a pressure of 4 to 6 bars is distributed by a ramp. (3) _10_ in each device for mixing. There are three mixing devices, one per color, one for blue, one for yellow, one for red. Each device being strictly similar, we will describe only one.

Each device comprises, at its head, a valve (2) (4) (5) comprising a venturi nozzle system for sucking the concentrated color shampoo found in the can (24) (6;) (23). Example: the concentrated yellow color shampoo in the can (24) the concentrated red color shampoo in the can (26), k concentrated blue color shampoo in the can (23). ).

Take as an example the preparation of the yellow mixture. The concentrated yellow shampoo is in the can (24). 10_ The level in the tray (18) is low and needs to be refilled.

The descent of the float (29) causes the opening of the water inlet in the automatic valve (2). This flow of water, through the venturi system draws through the pipe (6) the concentrated yellow shampoo in the can (24) _ Then two components flow through the pipe (30) in the tank (28) making Thus, the float (29) was raised to the desired level, causing the valve and the venturi system to break.

This' allows me to maintain a constant level of the mixture obtained, concentrated shampoo yellow color plus water, in the tray (281

The tank (28) is united, at its lowest part, with an electrova

The venturi system incorporated in the valve comprises a nozzle (39) which allows, according to the calibration chosen, to dose the amount of shampoo that is red and yellow.

The same process is repeated for the concentrated color shampoo drill (26) with the valve system (4) thus obtaining a red mixture in the tray (37-! ID_ The same process is repeated for the concentrated shampoo of blue color ( 23) with the valve system (5) thus obtaining a blue mixture in the tank (38).

Since the hyper concentrated and colored shampoo, yellow, red or blue, is suitable, it is necessary to prepare the mixture according to the application according to the application.

Following these movements, are obtained three trays filled, at a chosen level, three _45_ mixtures, concentrated shampoo color plus water: yellow mixture in the tray (28), mixture muge in the bin 07) blue mixture in the tray (38 ).

Each bin is equipped. at its lowest point, a solenoid valve (27).

The second system comprising the power supply and the car will allow, thanks to a pump, to prepare and route the mixture to its emulsion zone by adding air, before its distribution.

When a request for foam is activated at the level of the commands i the automaton (9) will open by a relay system (10) in a sequential manner, the solenoid valves (27).

Example: _25 .. A user the brush requests the sending of foam, his command (8 to the automaton (9) which will transmit to the relay (10) the order of opening of the électmvame _4 -

(27) yellow mixture, tray (28) for 15 seconds - the time of this time takes place on the

During 15 probes, this mixture has to flow through the collector (41) to the pump (11). This elution is alone in the collector, because the other two electrovamus - blue tank (38) and red tank (37) ) are closed.

The pump (11 operated by the compressed air coming through the pipe (42), the 4 bar is obtained through the regulator manometer (18), the valve heard open and electao failure (21 having been opened by the automaton receiving the command (8) _

This yellow mixture, after having been sucked by the pump (II), will be discharged by the latter into the pipe (43).

mple, that the brush that issued the command

The third system, that of disco ution, in play. In reality, all these operations are simultaneous t

r the automaton (9) will then open :. The solenoid valve (14) controlled by the automaton (9) will blow compressed air against the yellow mixture. This au-compressed has a psion of 2.5 bars obtained g racemanometr-regulator (19L

The air and color mixture thus obtained and emulsified is coughed towards the brush via the pipe (16) connected by the flexible hose (31) and the foam.

After 15 waves, the solenoid valve (27) of the yellow mixing tank (28 will close the solenoid valve (27) of the red mixing tank (3'T) will open for 15 seconds, the solenoid valves (27) of the tank yellow mixture (28l and blue mixing tank _25_ (38) élan! closed_

pn distribution by the pump (11 reproduce through electrovan (12) and (14) and emulsion able, eject to the brush by the conduat a red foam, _5_ It is understood that the control is always activated, the electrovann (14) being always managed by the automaton (9) and its relay (10).

We get, well, at the. brush a bead and an effusion of yellow foam (36) followed by a red foam (35).

_5_: fis 15 seconds of red foam, the automaton (9) will give the order to close the solenoid valve (27) of the red mixing tank (37) and to open the solenoid valve (27) of the blue mixing tank ( : ilf), the solenoid valve (_7) of the yellow mixing tank (28) remaining closed_

As in the two previous movements, the blue mixture will be sucked before _10_ to be pumped back by the pump (it} still to the air pressure coming through the pipe (42), the blue mixture returning to the distribution valves ( 12) and air supply (14) through the pipe (43) before being expelled through the outlet (16) to the brush via the plastic pipe (31) and the handle (3).

At this moment arrives at the blue island.

The movement cords are different, blue (34) red (35 *) and yellow following each other as long as the control is in Te This cycle is activated. the yellow as long as the 20_ The supply of the bins in color concentrated water shampoo is done automatically thanks to the system of its valves, including the system sales and actuated by the float which makes it possible to maintain a constant level in these tanks (28) (37) ) (38l_

When the control is deactivated, all the solenoid valves (27) red .. (27) blue _25_ and (27) yellow, as well as the solenoid valve air inlet (21) the solenoid valve mixing (12) and dispensing emulsion air (14) will close_

The setting of the automaton (9) makes it possible to act on the duration of the cycles.

The air and mixing adjustments at the solenoid valves mixing and distribution of air (14) allow to obtain the smoothness, firmness and consistency desired for the foam.

The suction and expulsion power of the pump (II) of the color mixing volume selected and sequenced by the controller (9) is adjustable with the pressure gauge (18). The regulator pressure gauge (19) adjusts the emulsion by adjusting the pressure of the compressed air. For proper operation, the pressure in the pressure gauge (18) must always be greater than 2 bar at the pressure gauge (19). The stronger the pressure on the pump (II) the faster the suction and expulsion.

Example of adjustment of the emulsion solenoid valves (14 (17) equipped with intake tune: A lot of air, we obtain a very voluminous and well-formed foam With more product, we obtain a foam more liquid and less formed but pl - _11 colored

The adjustment of the admission of the quantity of mixture to be emulsified before the outlets (15) and (16) is made with the solenoid valves (12) and (13) equipped with an intake control system.

The colors do not mix because, at no time, they are in coma _20_ extended between them .. Indeed, the sequential distribution system managed by the automaton 9) makes it possible to obtain this ratio.

The combination of all these settings makes it possible to obtain shades of color and consistency of the foam_
