Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a car washing device for large vehicles such as trucks and buses, and is particularly useful when washing a vehicle by moving the vehicle by itself in a car washing device that is stationary at a fixed position. The present invention relates to a car washing device capable of washing the front and rear sides of the car in addition to both sides.

Conventionally, car wash devices for small cars, such as those installed at gas stations, have been generally used as car wash devices for vehicles. Since the car was washed using a water fountain and a rotating brush, not only the sides and top of the vehicle but also the front and rear sides could be washed at the same time. However, such mobile car washing equipment is currently too large to be used for washing large trucks, buses, etc., and cannot be put to practical use. Therefore, as a car wash device for such large vehicles,
It is conceivable that the car wash device is stationary, and the vehicle is driven through it, spraying high-pressure washing water on both sides and the top and bottom to wash the car in a short period of time. The vehicle passes completely by itself from the entrance to the exit of the car wash equipment, and the fountain nozzle is stationary, so washing water cannot be sprayed on the front and rear of the vehicle, and the front and rear of the vehicle must be washed by hand. The disadvantage was that washing the car was difficult and took a long time.

Furthermore, Japanese Patent Application Laid-Open No. 1972-1972 discloses a tire washing machine equipped with a water injection pipe capable of injecting water from the front and rear of a vehicle.
Since this is a dedicated device for cleaning vehicle tires, this water injection tube is installed in the width direction of the vehicle and below the tires so that the tires can pass over them. Therefore, the water injection pipe has the disadvantage that it is impossible to wash the front or rear side of the vehicle body. In addition, since the water injection pipe is a fixed type,
There was a drawback that the water was sprayed in a linear manner, making it impossible to thoroughly clean a wide area.

The present invention has been made in order to eliminate the drawbacks of the prior art described above, and its purpose is to make a vehicle such as a large truck or bus self-propelled and spray washing water onto the vehicle from a fountain nozzle. A plurality of fountain pipes are provided horizontally and swingably on the side of a self-propelled vehicle and configured to allow washing from the side to the top of the vehicle; It is attached to the front and rear ends of the fountain pipe, and the front end is bent in a V shape toward the rear of the vehicle, and the rear end is bent in a V shape toward the front of the vehicle. By providing a fountain nozzle that sprays washing water while swinging toward the front or rear surface of the vehicle,
The purpose is to make it possible to wash the front and rear sides of a car in addition to the top and bottom sides at the same time, thereby making it easier to wash large vehicles and improving the efficiency of the car wash operation. Another purpose is to make it possible to wash the front and rear surfaces of the vehicle as well as the sides of the vehicle by spraying water from a swinging fountain nozzle, so that the entire surface of the vehicle can be thoroughly washed. It is to do so.

In short, the present invention provides a plurality of water fountain pipes that are horizontally and swingably provided on the sides of a self-propelled vehicle and are configured to be washable from the sides to the top of the vehicle, and the front end portions of the water fountain pipes. It is attached to the rear end part, and the front end part is bent in a V shape toward the rear of the vehicle, and the rear end part is bent in a V shape toward the front of the vehicle, respectively, and is attached to the front surface of the vehicle.

The present invention is configured as described above, and its operation will be explained below.

The vehicle 28 is driven by itself and enters the car wash device 1 from the entrance side in the direction of arrow A, and the driver opens the window and operates an external operation switch (not shown).
After turning on, close the windows and move the vehicle 28 forward. When the operation switch is turned on, the pump and motor 13 rotate, and the pump sucks up the cleaning water from the water tank and supplies it to the first and second water supply pipes 2.
a, 2b. The first and second fountain pipes 3a and 3b are connected to each other by rotation of the motor 13 via a pulley 13a, a chain 19, a rotating crank 14, first and second connecting rods 15a and 15b, and a swinging link 16, for example. The cleaning water is oscillated by an angle of 2.degree., and the nozzle 4 injects cleaning water to a pressure of about 8 kg/ ^cm.sup.2 onto the vehicle 28, for example.

By spraying the washing water onto the vehicle 28 while swinging at an angle of, for example, 60 degrees, in addition to the action of the washing water opening itself and spreading over a certain range when it comes out of the nozzle 4, the spreading Since the center of the nozzle 4 moves, the state changes from the conventional "line washing" state to the "surface washing" state, and not only can a wider area of the vehicle 28 be efficiently washed, but also the swinging of the nozzle 4 allows the cleaning water to be Since the spray direction changes every moment, dirt that is difficult to remove with spray from one direction can be easily removed. Moreover, since the washing water is sprayed toward the front surface 28a and the rear surface 28b of the vehicle 28 from the V-shaped nozzles 4b attached to the front and rear ends of the second water fountain pipe 3b, this type of conventional car washing device The front surface 28a and rear surface 28b of the vehicle 28, which could not be washed in the conventional method, can be automatically washed.
