Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a car washing method for cleaning a vehicle, and in particular, when washing or waxing is performed by rotating a car wash brush, washing water and wax are discharged to the outside of the car washing device. The present invention relates to a car washing method that can prevent the scattering of.

[Prior art 11I] For example, as is well known, a gate-type car washing device has a top brush arranged horizontally in a gate-shaped frame to wash the roof as soil, and a top brush arranged vertically to mainly wash both sides of the car. The car is equipped with a pair of left and right side brushes, and a pair of left and right rocker brushes arranged approximately vertically, which mainly clean the lower surfaces of the doors and around the tires. Cleaning and waxing are performed by rotating each brush while spraying cleaning water (or water mixed with detergent) or wax from the shower nozzle. At this time, as shown in Figures 4 and 5, due to the centrifugal force caused by the rotation of the top brush AJ5 and side brushes or rocker brushes B, splashes of wash water and wax C are released from the front opening of the car wash device. There is a problem of it scattering outside and contaminating it. In particular, since the front of a car wash device is often installed facing the road, droplets flying from the front cause a nuisance to passersby. In order to solve this problem, a car wash device is provided with a curtain installed around the front opening to prevent scattering. Since it is not possible to take a sufficient height to prevent scattering, the effect of preventing scattering is not sufficient.

Note that FIG. 2 is a schematic diagram for explaining the present invention in detail, and for example, the liquid feed pipe 13 extends in the vertical and horizontal directions as shown in FIG. 1, but for the sake of explanation, FIG. shown horizontally.

The blower device 2 is used during the rotation of the car wash brush and in the final stage of cleaning, and is installed in the main part of the frame 1 and has a top air outlet 11 and a pair of left and right side air outlets 12. Air is sent from a blower 25 provided within the frame 1.

The top air outlet 11 is normally located at the upper position shown in the figure, but during the drying process, in order to improve the drying effect, it is raised and lowered by a lifting device equipped with a vehicle height sensor (not shown), and is positioned at a certain distance from the vehicle body surface. It is now possible to do so.

The high-pressure water injection device i3, the finishing wax application device 4, and the cleaning water injection device 5 all have liquid feed pipes 13, 14, and 15 that are piped across the inside of the frame 1. A plurality of nozzles 18, 19, 20 are provided in each of these liquid feed pipes 13, 14, 15 at intervals. And these liquid feed pipes 13.14.15
are each of the above-mentioned brushes 6.7.8 in the frame body 1.
At least the liquid feed pipe 13 in the high-pressure water injection device 3 is placed in front of the liquid feed pipe 15 in the cleaning water injection device 5.

The top brush 6 is arranged horizontally so as to cross the inside of the frame 1, and the rocker brush 7 and side brush 8 are arranged vertically so as to be rotatable, with each pair being located on the left and right sides of the vehicle. .

The polish wax application device 9 and the rinsing device 10 are
Each of them has a liquid feed pipe 16.17 that runs across the inside of the frame 1, and each of these liquid feed pipes 16.17 has a plurality of nozzles 21.22 arranged at intervals. It is set apart. And these liquid feed pipes 16

Note that the cleaning water injection device 5, the rinsing device 10, the finishing wax coating device 4, and the polishing wax coating device 9 can each share one unit by using a switching valve, for example.

The car wash apparatus configured as described above washes a car according to the car wash process described below.

The vehicle is stopped at a predetermined position between the rails 24 and 24. When the frame body 1 moves back and forth, the high-pressure water injection device 3 is first activated to inject the high-pressure water sent to the liquid feed pipe 13 onto the vehicle body surface through the nozzle 18. This high-pressure water blows away the dirt and sand that is stuck to the surface of the vehicle, especially the dirt that is stuck around the tires and the lower part of the door. At the same time, the blower 25 is driven at low speed and blows air out from the top air outlet 11 located at the upper position shown in FIG. ff13 to form an air curtain E around the front opening of the frame 1.

Next, the cleaning water gQ injection device 5 is activated to spray the cleaning water sent to the liquid supply pipe 15 onto the vehicle body surface through the nozzle 20 to wash away dust while cleaning the top brush 6, rocker brush 7, and side brush 8. Brush and wash the vehicle while rotating each of them. During this brushing cleaning, as shown in FIG. 3, the splashes C of the cleaning water scattered due to the centrifugal force caused by the 6 to 80 rotations of each brush are blocked by the air curtain E and are externalized from the front opening of the frame 1. This prevents the product from scattering.

Next, when the frame body 1 is going back, the polish wax application device 9 is activated and the polish wax sent to the liquid feed pipe 16 is sprayed through the nozzle 21 to apply polish wax as an undercoat to the vehicle body surface. The vehicle is polished while rotating the top brush 6, rocker brush 7, and side brush 8, respectively. During this polishing, the polishing wax droplets C scattered due to the centrifugal force caused by the rotation of each brush 6 to 8 are blocked by the air curtain E and scattered to the outside from the front opening of the frame 1. Prevented.

Furthermore, when the frame body 1 is moved back and forth, the finishing wax application device 4 is activated to spray the finishing wax sent to the liquid feed pipe 14 onto the car body surface through the nozzle 19 while applying it to the top brush 6. The rocker brush 7 and side brush 8 are each rotated to perform waxing on the vehicle. At this time, the air curtain E similarly prevents the finishing wax droplets C from scattering to the outside from the front opening of the frame 1.

When the frame 1 returns again after 7i2, the rinsing device 10 is activated to supply the clean water sent to the liquid feed pipe 17 to the nozzle 22.
After completely rinsing off the excess wax that has been applied to the vehicle body surface through the
By blowing air from the pair of left and right side air vents 12, water droplets on the vehicle body surface are blown away or evaporated, thereby drying the vehicle body surface and completing the entire process of cleaning the vehicle.

[Summary] As explained above, according to the present invention, the car wash brush is rotated while blowing air from the air outlet connected to the blower provided on the outside of the car wash brush to wash the car. Washing water and wax scattered by centrifugal force are blocked by an air curtain formed by air blowing from the air outlet, preventing them from scattering to the outside of the car wash apparatus, and contaminating the outside. Note that the air curtain was formed only at the front opening with air blown from the air outlet of the drying air blower, but separate air curtains were provided at the front and rear of the frame, and a separate air blower was installed from the air curtain. Similar effects can be obtained by blowing out air.
