No contact carwash system
FIELD OF THE INVENTION
[001] The present invention relates generally to washing but more particularly
to a system and method of washing a car without the need for
scrubbing.
BACKGROUND OF THE INVENTION
[002] Car wash are a great invention but one problem has to do with the
brushes that can get snagged in various parts of a vehicle such as a
sports rack, antenna, rear view mirrors, trims, etc. Given the huge
variety or car makes and models plus all the possible optional
accessories, it is easier to find a way to eliminate brushes or direct
contact with the vehicle rather than finding brushes that will not get
caught. The problem with car wash offering a "no contact" washing
feature is that they are not as efficient as a brush car wash.
[003] Over the years, various inventions pertaining to the field of "no
contact"
car wash systems have been developed. In one such system, the
surface of the car is first covered with a water soluble, agitated liquid
cleaner which has been at least partially foamed. Then, the surface of
CA 02596931 2007-08-13
2
the car is blasted with water soluble beads under sufficient pressure to
apply a frictional cleaning motion to the liquid cleaner, but with
insufficient pressure to damage the car surface by excessive abrasion.
After the blasting step, the liquid cleaner and water soluble beads are
rinsed by the application of a high pressure water spray to the vehicle.
[004] Another invention describes a supporting frameworks wherein vehicles
are parked and washed while they are stationary. Chemical lines supply
chemicals (such as detergents, waxes, etc.) to water lines, and the
chemicals and water are mixed in downstream mixing modules. The
mixing modules are preferably provided in the form of vessels having
enlarged flow areas, and may contain baffles or other turbulence
generators therein. The chemical/water mixtures leave the mixing
modules in post-mix lines to which gas supply lines may be connected
for the purpose of generating foam, which is then delivered in the wash
bay from a downstream delivery system. The downstream foam
pressure has little or no effect on upstream mixing of chemicals and
water, and thus foam having highly uniform properties is generated.
[005] In yet another invention, fluid is conducted along a conduit that is
mounted to a support structure so as to permit selected displacements
thereof along a longitudinal axis of the conduit and selected rotations
thereof about the longitudinal axis. The fluid conducted through the
conduit can be conducted through at least one of a plurality of nozzles
CA 02596931 2007-08-13
3
that are mounted to the conduit. The conduit is selectively reciprocated
along the longitudinal axis by a first driving device. In addition, the
conduit is rotated about the longitudinal axis by a second driving device.
As the conduit is displaced both about and along the longitudinal axis,
5 the fluid forced through the nozzle is directed toward the outside surface
of an object to be washed.
[006] Still another invention describes a car wash method which includes the
steps of positioning a vehicle adjacent a set of sensors , measuring a
variety of parametric data relating to macroscopic debris and surface
film formed on a surface of the vehicle, calculating the quantity of
presoak components to be added to a presoak solution, blending the
presoak solution, and applying the presoak solution to the vehicle.
Quantities of presoak enhancing agents are also calculated from the
sensor readings along with the calculation of the number and type of
wash cycles required for the vehicle. The method is implemented by
customizable car wash blending system which incorporates a plurality of
sensors in communication with a computer control system. Computer
control system communicates with a series of sub-systems in order to
apply the presoak solution and wash the vehicle.
20[007] Finally, there is even a car wash system that uses electromagnetic
waves set between 100 nm et 2000 nm that break down the molecular
structure of dirt particles.

SUMMARY OF THE INVENTION
[008] In view of the foregoing disadvantages inherent in the known devices
now present in the prior art, the present invention, which will be
described subsequently in greater detail, is to provide objects and
advantages which are:
[009] To attain these ends, the present invention generally comprises a
plurality of holding tanks, each said holding tanks being connected to a
dosing pump, one dosing pump to each product to be mixed. The dosing
pumps measuring quantities for each product. Water from a water line
along with the products are then sent to a centrifuge pump for admixing
into an admixture. A pressure tank provides pressure controlled by a
pressure relief valve the pressure then reduced by a reduction valve.
The admixture traveling through an admixture line. Pressurised air
introduced to an air line and air from that air line and the admixture
blended into a lather generator and then fed to a spray line exiting
through a spraying gun.
[0010] The lather is a specially formulated solution that creates a thick
lather
that traps and drags down the particles that soil the vehicle. A quick
water rinse made after having the vehicie soak in the thick lather is all
that is needed to wash and rinse the vehicle.

[0011] There has thus been outlined, rather broadly, the more important
features of the invention in order that the detailed description thereof

10BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Fig. 1 Schematic view of the process.
DETAILED DESCRIPTION
[0016] A no contact carwash system (10) has a plurality of holding tanks (12),
each one connected to a dosing pump (14). These dosing pumps (14)
carefully measure the proper quantities for each product. Water from a
water line (16) along with the products are then sent to a centrifuge
pump (18) for admixing, the solution then passes through a check valve
(28). A pressure tank (20) provides a pressure of between 100-120- psi
which is controlled by a pressure relief valve (30) which maintains a
pressure between 100-120 psi then reduced to about 80 psi by a
reduction valve (22). From there, the admixture travels through an
CA 02596931 2007-08-13
7
admixture line (32). In parallel, pressurised air is also introduced to an
air line (24), reduced to about 75-85 psi by an air reduction valve (26).
Air from the air line (24) and the admixture from the admixture line (32)
are blended into a lather generator (34) and then fed to a spray line (36)
exiting through a spraying gun (38).
[0017] Solenoid valves(40) located at various location provide control over
the
flow of the admixed solution. There are also a number of valves (44) to
control the flow as well as pressure gauges (42) to monitor pressure
throughout the no contact carwash system (10).
10[0018] The lather thus created by the no contact carwash system (10) with
the
use of proprietary ingredients is very thick and as the lather slowly slides
downward by the action of gravity, it breaks down the static on the
vehicle so that dirt particles no longer cling to the vehicle. After a while,
a rinse clears off the lather and the dirt with it.
15[0019] As to a further discussion of the manner of usage and operation of
the
present invention, the same should be apparent from the above
description. Accordingly, no further discussion relating to the manner of
usage and operation will be provided.
20[0020] With respect to the above description then, it is to be realized that
the
optimum dimensional relationships for the parts of the invention, to
CA 02596931 2007-08-13
15 8
include variations in size, materials, shape, form, function and manner of
operation, assembly and use, are deemed readily apparent and obvious
to one skilled in the art, and all equivalent relationships to those
illustrated in the drawings and described in the specification are
intended to be encompassed by the present invention.
[0021] Therefore, the foregoing is considered as illustrative only of the
principles of the invention. Further, since numerous modifications and
changes will readily occur to those skilled in the art, it is not desired to
limit the invention to the exact construction and operation shown and
described, and accordingly, all suitable modifications and equivalents
may be resorted to, falling within the scope of the invention.
