Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a car washing method using a car washing machine equipped with a rotating brush and capable of washing and waxing an automobile body.

[Background of the Invention] In general, the above-mentioned type of car wash machine performs waxing by applying a cationic water-based wax after washing the car body. This cationic water-based wax is chemically adsorbed onto the car body, so it can be waxed easily, but it has the disadvantage that it is less glossy and does not have long-lasting water repellency compared to ordinary solid wax. In addition, cationic water-based wax is also adsorbed to the glass surface and remains as an oil film, which may adversely affect the driver's visibility, especially in rainy weather.

In order to address these issues, we investigated the use of an anionic wax emulsion containing anionic surfactants, wax components, solvents, water, etc. as main components instead of cationic aqueous waxes. This anionic wax emulsion is sprayed after diluting the undiluted solution with 30 to 50 times as much water. The sprinkled wax emulsion separates from the water and becomes gel-like particles that adhere to the car body, so all you have to do is brush it with a rotating brush and apply it evenly.The wax emulsion applied in this way has a high density. It forms a wax film with a rich luster and long-lasting water repellency. In addition, this anionic wax emulsion is
Unlike the above-mentioned cationic water-based wax, it is not actively adsorbed to the car body surface and acts only on painted surfaces and oil film surfaces, so it does not adhere to clean glass surfaces and does not form an oil film, which is a desirable property. have.

However, on the other hand, if even a small amount of oil film remains on the glass surface, the wax emulsion will act on this oil film surface.
This creates an extremely strong oil film, which poses a danger of obstructing the driver's field of vision even more than the oil film caused by water-based wax.

Also, as mentioned above, anionic wax emulsions are not actively adsorbed to the car body surface, so if even a small amount of detergent remains on the car body, its surfactant components will wash it off with the water, making it difficult to apply wax properly. I have a problem where I can't.

[Purpose of the Invention] The present invention addresses these points and provides a car washing method that does not form an oil film on the glass surface and allows anionic wax emulsion to act effectively to obtain a high wax effect. To do something for the purpose of doing something.

[Structure of the Invention] The present invention includes a cleaning step of brushing the vehicle while spraying the detergent, after a pre-step of spraying an oil film remover on at least the windshield of the vehicle, and a cleaning step of brushing the vehicle while spraying the cleaning water. The above object is achieved by washing the car in such a way that a rinsing process and a waxing process of brushing the car while spraying the wax emulsion are performed in sequence.

[Function] As a result, the oil film remover is applied to the windshield in the previous process, and this is brushed in the cleaning process, so the oil film attached to the windshield is completely removed.
In the subsequent rinsing process, the detergent and oil film remover are completely washed away, leaving the windshield clean and free of oil film, and the detergent from the car body is removed, allowing an anionic wax emulsion to be applied.

Before starting the car wash, as a pre-process, an operator first applies an oil film remover to the windshield using a sponge or the like.

This oil film remover is made of a detergent containing fine compound particles, and has a viscosity that does not easily flow off when the cleaning water or liquid agent is sprayed from the spray nozzle.

After this pre-process, the car wash starts using the car wash machine.

1 construction theft: First, as the main body 1 moves back and forth, the spray nozzle 10.
The cleaning process is carried out by brushing the windshield while spraying water with the spray nozzle 10' and spraying an aqueous solution of detergent a with the spray nozzle 11.In the windshield, the oil film remover applied in the previous process is brushed over the glass surface. The oil film attached to the surface is completely removed. Furthermore, water is sprayed from the rear spray nozzle 13 to rinse off the detergent and oil film remover.

As the car body 1 continues to go around, the spray nozzle 10
10' ・From 11-13, perform a rinsing process to completely wash away detergent and oil film remover remaining on the car body by brushing while sprinkling only washing water.

1 As the car body 1 continues to move back and forth, the waxing process is performed by brushing while spraying diluted anionic wax emulsion from the spraying nozzle 12, and then spraying water from the spraying nozzle 13 to perform the waxing process. Wash away excess wax.

m: As the main body 1 goes back, air is blown onto the car body from the blower nozzle 8 to perform a drying process, and the series of car washing operations is completed.

As mentioned above, in the previous process, an oil film remover is applied to the windshield to remove the oil film on the glass surface, and
The oil film on the windshield can be completely removed by brushing in the subsequent cleaning process. In addition, in the subsequent rinsing process, the waxing process is performed after completely washing away the detergent and oil film remover remaining on the car body.
On a clean windshield from which the oil film has been removed, the wax emulsion will flow down with the water without acting on it, and the wax emulsion will surely act on the painted surface of the car body from which the detergent has been washed away.

Note that the application of the oil film remover in the previous step can be performed automatically by a car wash machine without manual intervention. An example thereof will be explained using FIG.

An oil film removing agent spraying nozzle 36 is attached to the top blower nozzle 8, and is raised and lowered together with the blower nozzle 8. 37 is a pump for dispersing oil film remover. A known vehicle height sensor 3 using ultrasonic waves is installed at the front end of the car wash main body 1.

As the car wash main body 1 moves back and forth, the vehicle height sensor 37 detects the height of the top surface of the vehicle body, and when this detection position reaches a steeply sloped part such as a windshield, the reflected signal is transmitted to the vehicle height sensor 37. If this state of not receiving normally continues for a certain period of time, it will be recognized as a glass part and the top blower nozzle 8 will be lowered to an appropriate position. After this, wait for the difference in the front and back positions between the vehicle height setting: YF-37 and the blower nozzle 8, spray the oil film remover for a certain period of time, and furthermore, wait for the difference in the front and rear positions between the blower nozzle 8 and the top rotating brush 5. After moving the vehicle body 1 for the amount of time, the top rotating brush 5
The rotary brush 5 and blower nozzle 8 are then returned to their predetermined standby positions, and the vehicle body 1 is returned to the starting position to complete the previous process. .

[Effects of the invention] As is clear from the above explanation, even if an oil film is formed on the windshield, the anionic wax emulsion is sprayed after this oil film has been completely removed. No oil film is formed on the windshield, and there is no risk of adversely affecting the driver's visibility.

In addition, the detergent and oil film remover used are completely washed away from the car body, and the anionic wax emulsion effectively acts on the car body casing surface, resulting in a high waxing effect not seen with conventional water-based waxes. It will be done.
