Abstract

PURPOSE:To heighten remarkably washing effect and aim at the compaction and light-reduction of the whole device by providing an adjusting drive unit for adjusting a cleaning liquid nozzle to be in constant distance from the surface of a car body and a high pressure water nozzle for jetting high pressure water flow onto the body surface at the rear stage of the nozzle. CONSTITUTION:At the time of washing the front part of a vehicle, as the vehicle starts moving, washing pipes 35, 58 are rotated around an axis 38 by means of a cylinder 34 from the vertical direction to the horizontal direction and stop. When the vehicle approaches, a distance detector 37 fitted at the washing pipe 35 is actuated to open a solenoid valve so as to emit liquid from a nozzle 36 and perform washing. At the same time, the front face of the vehicle is washed in a fan form while the washing pipe 35 is being returned from the horizontal direction to the vertical direction by the cylinder 34. At this time, an injection device B moves at the same speed as the vehicle because the washing pipe and the vehicle are not in contact and also for the purpose of maintaining washing effect, and travels until the washing pipe 35 returns to the vertical direction while maintaining always constant distance. When the washing pipe 35 returns to the vertical direction, liquid emittance from the nozzle 36 and the running of the injection device B are stopped, and the front face washing is thus terminated.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a car washing device.

<Prior art> Conventional car wash equipment (mainly for commercial use) sprays detergent in the form of mist or foam onto the surface of the car body automatically or manually, and then presses an automated rotary car wash brush against the surface of the car body. Mud adheres to the surface of the car body using frictional force,
Removes dust, oil stains, etc.

For this reason, not only the brushes but also mud and the like that rotate along with the brushes cause countless scratches on the surface of the vehicle body. Especially for 11 tons of dark colored vehicles such as black and red,
Because these defects are so obvious, there are currently very few people who wash their cars using this method, and most people wash their cars by hand.

Also, since the brush cannot reach uneven areas such as the front and rear surfaces of the vehicle and the wheel caps, dirt is removed in advance before automatic brush cleaning.

In addition, in vehicles with external protrusions such as trucks, the brushes may become entangled with the protrusions during rotational movement, making rotational movement impossible or causing serious damage to the brushes.
The current situation is that you can't wash your car at all.

Purpose The present invention has been proposed to solve the above-mentioned drawbacks. In other words, without using a car wash brush, a high-performance detergent solution is sprayed at high pressure from a nozzle to remove dirt, debris, etc. adhering to the surface of the car body, and a high-pressure water stream is ejected from the next nozzle to completely remove dirt and detergent. The purpose is to provide a washing device.

<Means for solving the problems> The means for solving the problems according to the present invention are as shown in FIGS.
a cleaning liquid nozzle that sprays cleaning liquid onto the surface of the car body;
The cleaning liquid nozzle is equipped with an adjusting drive device (consisting of a Schilling, etc.) that adjusts the cleaning liquid nozzle to a certain distance from the vehicle body surface, and a high-pressure water nozzle that injects a high-pressure water stream onto the vehicle body surface at a stage subsequent to the nozzle.

In the above-mentioned problem solving means, the nozzle, etc. does not come into contact with the surface of the car body, so it does not cause scratches, and since the water flow reaches every detail, there is no need for preliminary cleaning before automatic cleaning, and there are no protrusions on the outside. It is also possible to wash vehicles such as trucks.

There are two methods of spraying cleaning fluid: a direct injection method and a rotary spraying method that creates a rotational motion in the water stream. In both cases, the air that is naturally or forcibly included in the cleaning fluid hits the surface of the vehicle while being compressed under high pressure. At the same time, the barge tries to return to its original unpressurized state and scatters, which generates an extremely extraordinary expansion force that hits the surface of the vehicle along with the water flow, greatly increasing the cleaning effect and making it possible to completely remove dirt that previously could not be removed. .

Additionally, by eliminating heavy brushes, there are fewer consumables and the weight of the cleaning section can be significantly reduced.
The entire device can be made smaller and lighter, and since there are no rotating parts, it is robust and less likely to break down, and the amount of power required can be reduced.

In addition, by using a movable car wash nozzle injection device mounted on a trolley, the relative speed with the vehicle can be changed freely.
By selecting the car wash speed based on the amount of dirt on the vehicle, the car wash time can be shortened and the consumption of detergent, water, etc. can be saved.

<Example> Hereinafter, an example of the present invention will be explained based on the drawings. Fig. 1 is an overall plan view of the car washing device of the present invention, and Fig. 2 is a side view of the same.
