the automobile to be cleaned is driven into the frame in the forward direction. In the moving process of the automobile during driving, the infrared sensors of the control module 11 measure the positions of the automobile head and the automobile wheels, the wheel hub cleaning nozzles 30 are controlled to be aligned with the wheel hubs from the two sides of the automobile to spray wheel hub cleaning agents, the prewashing nozzles 31 are then aligned with the middle lower part of the automobile to spray silt loosening agents, so that the thicker silt at the lower part of the automobile body becomes soft, and the absorption and reaction of the subsequently sprayed cleaning agents are facilitated.

Meanwhile, the chassis atomizing nozzle sprays atomized water to the bottom of the vehicle. The purpose is to properly cool the chassis and parts above the chassis, and reduce the risk of vehicle damage caused by temperature sharp drop caused by subsequent chassis flushing and cleaning.

After the vehicle is stopped stably, the automobile windshield sprayer fixed at the front upper part of the vehicle sprays glass cleaning agents to the windshield, and the cleaning sprayer for cleaning the front part of the automobile sprays front face cleaning agents to the head of the vehicle.

At the same time, the moving frame 13 is moved over the parked car, and the cleaning spray head 32 sprays the multifunctional cleaner to the entire car body.

The hub cleaning agent, the silt loosening agent, the glass cleaning agent, the multifunctional cleaning agent and the front face cleaning agent sprayed in the steps are subjected to heating treatment to accelerate the processes of permeation, absorption, emulsification and the like, so that the chemical agents are more fully reacted, and the waste and the meaningless consumption are reduced.

Next, the ultrasonic ranging sensor of the control module 11 measures the body contour data of the vehicle to be washed to obtain the height of the vehicle body at each position, the position of the side of the vehicle body, and the like. Therefore, in the subsequent steps, the high-temperature water vapor spray nozzle 33, the reclaimed water spray nozzle 34 and the cleaning water spray nozzle 35 can keep proper distances from the outer surface of the vehicle body as required, and a good liquid spraying effect is realized.

The high temperature water vapor can reach over 150 deg.c and may be used as effective heat source. The high-temperature water vapor is generally a gas-liquid mixture, the liquid drops of the high-temperature water vapor are in a fine-grained fog shape, the heat transfer effect is good, the temperature of the surface of the automobile can be quickly raised, and the concentration of the detergent covered on the automobile body cannot be greatly diluted. Meanwhile, the problems of high turbidity of the active agent, high specific energy consumption and the like which are faced by directly heating the detergent to the high temperature of more than 50 ℃ are solved. Generally, the data measured in the previous step is relied on in this step, and the control module 11 ensures that the high-temperature water vapor spray nozzle 33 is kept as close as possible to the vehicle body, so as to reduce heat loss and improve the operation effect.

The vehicle body is washed with the reclaimed water supplied from the sewage treatment device 12. The function of the device is that the vehicle can be washed by the large-flow reuse water, so that the use amount of the subsequent clear water is greatly reduced. Secondly, if large-flow and low-pressure water is adopted in the step, most of gravel hard dirt on the vehicle body can be removed, so that the subsequent clear water washing is suitable for adopting higher washing force, and the problem of vehicle paint scraping caused by the fact that the hard dirt slides on the surface of the vehicle body along with high-speed water flow can not be caused.

When the vehicle body is washed, water is sprayed to the chassis of the vehicle body to clean dirt such as mud, dust and the like attached to the bottom of the vehicle. The reclaimed water obtained after the sewage recycling treatment is also used in the process.

Then, the whole vehicle is washed with clean water. If the design goal is to completely remove the dirt on the vehicle body, the step is mainly a rinsing function, and low-pressure water is used for taking away the residual reclaimed water stain on the vehicle body. If the design aim is to remove the granular dirt on the surface of the vehicle body, the step is washed by high-pressure water, and the dirt is damaged, peeled and washed away by the impact force of the step, so that a more thorough decontamination effect is realized.

After the above steps are finished, the decontamination work in the cleaning stage is finished.

According to the automobile maintenance requirement, wax water is sprayed to the automobile body through the wax water spray nozzle 37, so that the paint of the automobile body is protected, the surface brightness is improved, and the anti-static and anti-fouling effects of the automobile body are enhanced. Then, the water removing part dries the vehicle body, the deflector rod 5 of the water removing part drives the wiping cloth 93 to swing back and forth, and the sleeve 914 reciprocates to drive the wiping cloth 93 to swing left and right, so that the vehicle body is wiped and water is removed.

Finally, the driver drives the vehicle away from the water removing area, strong wind is blown out by the floor type fan 8 in the driving away process, residual water at the lower part of the vehicle body is blown away, and the vehicle wiping cloth strip 82 on the air outlet 81 is also guided to the vehicle body 4 along with air flow to wipe the middle-lower part of the side surface of the vehicle body. Therefore, the whole car washing operation flow is completed.

The basic cleaning mode of the non-contact computer car washer selected by the embodiment is as follows: the automobile to be washed automatically enters the automobile washing area and then stops, in the process, a targeted chemical detergent is sprayed on each part of the automobile body, then the outline and the direction of the automobile body are measured by the control module, the movement of the movable frame and the opening and closing of the water pump and the electromagnetic valve are controlled, the operations of spraying the detergent on the surface of the automobile body, removing dirt of the automobile body by using high-pressure water washing, spraying bright water wax after the washing is finished, and the like are realized, and finally, the automobile is driven away from the automobile washing area of the automobile washer by a driver. In the cleaning and decontamination process of the vehicle, the machine automatically detects the liquid spraying, the water spraying and the water removal.
