The present invention relates to a system and method for washing and cleansing of vehicles in a closed environment. More particularly, the present invention relates to an automatic vehicle washing system and method thereof, in an efficient manner.

Background of the Invention

Automatic vehicle washing systems are known since decades and it has been observed that such systems, in general, contribute towards avoiding wastage of water and less wear and tear on the vehicles, reducing labour cost, and most importantly saving time in washing of the vehicles.

Despite of all the above advantages, installation of such systems has always been a problem as their bulky structure because of the involvement of so many sub-components and apparatuses does not support an easy assembly at desirable places, hence setting up the system for operation is a cumbersome task, therefore, unnecessarily consumes time in putting the system in operation. Also, such automatic vehicle washing system in an integrated form are incapable of being transported from one place to another.

In the traditional automatic vehicle washing systems, the washing conveyor or gantry ortrolley is configured to move overthe guiding rails on the floor on two lateral sides of the vehicle, this demands a proper relative alignment of the gantry on both sides every time the gantry is moved over the vehicle and the system is required to regularly keep a check on the same, thereby, adding complexity in the system. The pipelines for distributing water and chemicals for washing and cleansing of the vehicle are usually a single line and all the jet sprayers for spraying water and chemicals over the vehicle are to be incorporated in the same line, this causes imbalance between the pipe length and no. of jet sprayer to be provided per pipe. As a result, there is a significant pressure drop per jet sprayer, causing inefficient washing and leading to more water and power consumption than ideally required.

In addition to the above, the jet sprayers provided in the gantry unit of such washing systems do cover the vehicle surface area for washing, cleansing and drying of the vehicle, but very inefficiently as far the washing duration is concerned, and still leave dirt and water droplets after the washing is done. The traditional vehicle washing systems are also provided with tanks containing plurality of mixed chemicals which is to be employed for deep cleansing of the vehicle after pre-washing. The drawback here is that the chemicals are already mixed and are applied on the vehicle as per the instruction from pre-programmed controller, it is obvious to note that chemicals lose activity over time as far as its efficiency is concerned for dirt cleansing, therefore, employing the already mixed chemicals for cleansing impacts vehicle wash quality over time.

Further, in the traditional vehicle washing system, it has been found such systems are designed in such a manner that liquids or fluids leaks out of the system, as the washing procedure is not carried out in a complete closed environment, thereby, leaving a scope for leakage. In such systems, there is provided an option of recycling water and re-using the recycles water for the purpose of vehicle washing, but then, there is a separate system designed for water recycling which is a separate unit independently functioning in which the dirty water is fed and cleaned water is reclaimed for repetitive washing procedure, none of such systems are provided with an integrated water recycling and treatment unit operating in coordination with the controller of the vehicle washing system.

It is to be noted that the above known systems and methods have some of the aforementioned drawbacks, because although they solve the problem of washing vehicles to some extent, but they do so by involving an excessive complication of mechanisms and a high water and energy consumption, or at the cost of needing a large facility space, and still not efficient in terms of time and consistent wash quality.

It would be desirable, therefore, to develop an improved system and method for washing of vehicles, which is capable of being transported from one place to another and offers easy assembly and efficient washing, cleansing and drying of the vehicle in minimum time, and obviates to the challenges that exist in the prior arts leading to inefficient washing leading to excessing water and power consumption.

In addition to the above relative positioning and angular orientation of the water spraying means in the boom sprayer, there is provided a coaxial self-rotatable washing mechanism (14) for spraying water on to the vehicle, the functioning of the self- rotatable washing mechanism (14) in coordination with the water spraying means of the boom sprayer augments washing and cleansing of the vehicle by effectively spraying water, foam, shampoo and wax even in the hidden deeper region of the vehicle for enhanced washing and cleansing in minimum time. Further, the coaxial self-rotatable washing mechanism (14) is having a pair of tubular wands (15) oppositely oriented only to contain angularly slitted nozzles at their ends, wherein the tubular wands rotates around the axis of rotation (R) for spraying water on to the vehicle, wherein the junction point of the tubular wands (15) coincides with the axis of rotation (R) and disposed in a holder (17) having nylon for the rotational axis support. The self-rotatable washing mechanism (14) is connected with a high-pressure water source, wherein water received at high pressure enables the entire tubular wands (15) to rotate automatically without requiring any powered motor by reciprocating the force generated on one side of the tubular wand (15). The outlets of the angularly slitted nozzles (14a) provided on the ends of the tubular wand (15) are having a phase difference of 180° helping in the inertial rotation of the tubular wand (15) around the axis (R) of rotation. The spread angle of the angularly slitted nozzles (14a) varies between 15° and 30°. Therefore, employing the spraying via the optimised angular orientation of the spraying means (13a) of boom sprayer (13) functionally with rotatably spraying of water through the angularly slitted nozzles (14) of the above-mentioned spread angle, enables the gantry assembly (11) to cover the maximum vehicle area, penetrating even the obscured regions of the vehicle in minimum time for washing by using minimum no. of nozzles and spraying means. Thereby, making the vehicle washing time efficient. The boom sprayer (13) further extends below the vehicle mounting platform (5) for washing inner bottom regions of the two-wheeler.

Referring to Figure 4, in accordance with one embodiment of the present invention, side view of the gantry assembly is shown with a vehicle (V) mounted on the vehicle mounting platform (5), the gantry assembly is mounted on a rail guided ceiling (10), wherein the side member (1 1 a and/or 11 b) of the gantry assembly is provided with sensors (12) for sensing the length of vehicle and informing the controller (7) about the same, and then accordingly, controller instructs for constraining the back and forth movement of the gantry assembly to only across the vehicle length so as to avoid unnecessary wastage of water. There are a few other sensors (12) provided in the gantry assembly for checking safety check points prior to initialising the vehicle washing process. The boom sprayer (13) provided on the side members of the gantry assembly (11) extends towards and beneath the vehicle mounting platform (5).

Referring to Figure 5, in accordance with one embodiment of the present invention, side members (11 a or 1 1 b) of the gantry assembly (1 1) are housed a boom sprayer having water spraying first and second lines (13a and 13b) embedded inside the frame of the side members (1 1 a and 1 1 b) and self-rotatable washing mechanism (14) provided in the first spraying line of the boom sprayer (13), their relative positioning and angular orientation are optimised for covering maximum vehicle area in minimum time. The spraying nozzles means (13c and 13d) are alternately and parallelly arranged in two different water spraying lines so as to target upper and lower region of the vehicle (V) for washing using separate spraying nozzles (13c and 13d).

Referring to figure 6, boom sprayer 13 housed in the side members of (1 1 a and 11 b) of the gantry assembly, is having separate lines (13e, 13f and 13g) for spraying chemicals such as shampoo, foam and wax, and they are not the same chemicals contained in the tanks of chemical mixing system (21) for water treatment.
