Automatic vehicle wash and wax system
A vehicle wash and wax system ( 10 ) comprising a liquid coating dispensing station ( 11 ) and a waterfall dispensing station ( 20 ) to dump a continuous sheet of fluid ( 25 ) onto the liquid coating on the surface of the vehicle ( 30 ). The waterfall dispensing station ( 20 ) has a tank structure ( 21 ) with a weir member ( 32 ) to form the continuous liquid sheet dump ( 25 ). Chemical agents, such as optical brighteners, dyes and a carnauba wax emulsion may be introduced in the waterfall dispensing station ( 20 ) for the continuous liquid sheet dump.
1. A vehicle washing system comprising:
a) a coating application apparatus constructed and arranged to apply a coating formulation onto a vehicle; and
b) a water sheet application apparatus constructed and arranged to apply a continuous sheet of water onto the coating formulation applied to the vehicle to create a coating solution and to evenly disperse the coating formulation on the vehicle, the water sheet application apparatus including a chemical injection device to inject a carnauba wax emulsion into a water supply for said continuous sheet of water.
2. The vehicle washing system of claim 1 , wherein said coating application apparatus has a surface reactive silicone spray dispenser.
3. The vehicle washing system of claim 1 , wherein the water sheet application apparatus applies a continuous sheet of unheated water onto the coating applied to the vehicle.
4. The vehicle washing system of claim 1 , wherein a lowermost portion of the water sheet application apparatus is arranged above the vehicle onto which the water sheet is to be applied, and wherein the water sheet application apparatus applies the continuous sheet of water by dropping the water from a position above the vehicle, allowing the sheet of water to fall freely onto the vehicle.
5. The vehicle washing system of claim 1 , wherein the water sheet application apparatus includes a dispensing conduit arranged above the vehicle to drop water directly onto the vehicle to apply the continuous sheet of water onto the coating applied to the vehicle.
6. The vehicle washing system of claim 1 , wherein the water sheet application apparatus applies the sheet of water onto the coating formulation to create a coating solution by mixing the sheet of water with the coating formulation.
7. The vehicle washing system of claim 1 , wherein the water sheet application apparatus applies the sheet of water onto the coating formulation to create a coating solution by causing the coating solution to dissolve.
8. The vehicle washing system of claim 1 , wherein the water sheet application apparatus includes:
a liquid tank;
a water supply to supply water to the tank;
a wax supply to supply wax to the liquid tank; and
wherein the water sheet application apparatus is adapted to apply a sheet of liquid solution including water and wax onto a vehicle beneath the liquid sheet application arrangement.
9. The vehicle washing system of claim 8 , wherein the water sheet application apparatus applies the sheet of liquid solution to create a coating solution with a coating material on the vehicle, and to disperse the coating material on the vehicle.
10. The vehicle washing system of claim 8 , wherein the coating application apparatus is adapted to apply a coating material to the vehicle, prior to application of the sheet of liquid solution, wherein the water sheet application apparatus applies the sheet of liquid solution to create a coating solution with a coating material on the vehicle, and to disperse the coating material on the vehicle.
11. The vehicle washing system of claim 8 , wherein the water sheet application apparatus is adapted to apply a sheet of liquid solution including water and wax onto a vehicle beneath the water sheet application arrangement by releasing the sheet of liquid solution from a position above the entire vehicle, allowing the sheet of liquid solution to drop freely from the liquid sheet application arrangement to the vehicle via gravity.
12. A vehicle washing system comprising:
a) a coating application apparatus constructed and arranged to apply a coating formulation onto a vehicle; and
b) a water sheet application apparatus constructed and arranged to apply a sheet of water onto the coating formulation applied to the vehicle to create a coating solution and to evenly disperse the coating formulation on the vehicle, the water sheet application apparatus including a tank structure, a water supply and a weir attached to said tank structure.
13. The vehicle washing system of claim 12 , wherein said water sheet application apparatus further includes a water heater for providing to said tank structure water heated to a range of approximately 100-150° F. (38-66° C.).
14. The vehicle washing system of claim 12 , wherein said weir is disposed at angle range between 15 and 20° with respect to a horizontal plane and wherein said water sheet application apparatus dispenses between 5 to 15 gallons (18.9-56.8 liters) of water per application.
15. The vehicle washing system of claim 12 , wherein said tank has opposing sides and wherein a water inlet is disposed in each said side.
16. The vehicle washing system of claim 15 , wherein a pipe extends between said opposing sides within said tank and wherein said pipe has a plurality of slots spaced in the bottom thereof.
17. The vehicle washing system of claim 16 , wherein said tank has a trapezoidal cross-sectional configuration.
18. A vehicle washing system comprising:
a )a coating application apparatus constructed and arranged to apply a coating formulation onto a vehicle; and
b) a water sheet application apparatus constructed and arranged to apply a continuous sheet of water onto the coating formulation applied to the vehicle to create a coating solution and to evenly disperse the coating formulation on the vehicle, the water sheet application apparatus including a chemical injection device to inject a surfactant, a dye and an optical brightening agent into a water supply for said continuous sheet of water.
