The present invention relates to an automatic steam car washing apparatus, and more particularly, to an automatic steam car washing apparatus that can efficiently wash a vehicle by a simple configuration using steam and compressed air.

In general, an automatic car wash for a vehicle includes a vehicle-type car wash method in which a car is gradually washed into an automatic car wash device according to a driving method, and the automatic car wash is moved back and forth after the vehicle enters the inside of the automatic car wash. There is a car wash type mobile car wash method.

In both vehicle-type car washes and car washes, both car-type and car washes sense the position of the vehicle or the entry of the vehicle by means of a position sensor or proximity sensor attached to the frame of the automatic car wash. Treatment processes for primary cleaning, brush rotation, secondary rinse, dehydration and drying by air blowing are generally similar.

In addition, the outer side of the steam supply pipe 11, the rotating body 20 is installed rotatably around the steam supply pipe (11). Rotating body 20 is formed in a disc shape, the center hole is inserted into the outer periphery of the steam supply pipe 11, the weak rotational force between the steam supply pipe 11 and the rotating body 20 via a bearing 21 In addition, the rotation of the rotating body 20 can be made smoothly.

The rotating body 20 is provided in plurality along the longitudinal direction of the steam supply pipe (11). In the present embodiment, it is shown that the three rotating bodies 20 are installed at regular intervals, but is not limited thereto.

A plurality of blade pieces are disposed in the rotor 20 in the circumferential direction around the steam supply pipe 11 to generate the rotational force of the rotor 20 by the high pressure steam injected from the steam nozzle 13. 22 is installed.

In this embodiment, the blade piece 22 is formed in a plate shape, one end is located outside the rotor 20, the other rear end of the wing piece 22 is located on the steam supply pipe 11 side to approximately the rotor 20 ) Is installed in the radial direction and installed at constant intervals in the circumferential direction.

At this time, the blade piece 22 is provided in the injection zone of the steam injected from the steam nozzle 13 of the corresponding position, it is installed slightly inclined with respect to the injection direction of the steam (see Fig. 4) from the steam nozzle 13 It is possible to increase the rotational force of the rotating body 20 to the maximum by effectively operating the injection pressure of the strongly injected steam.

In the present embodiment, the blade piece 22 is illustrated as being installed on the upper surface and the lower surface of the rotating body 20, respectively, but is not limited to this, may be provided only on one of the upper and lower surfaces.

In addition, the plurality of wing pieces 22 are all connected to the upper end is covered with a cover 23, one side of the wing piece 22 collides with the steam injected from the steam nozzle 13 is one end of the other It is formed into a curved surface concave in the rear end direction, so that the rotational force can be increased.

The washing brush 25 is installed on the circumferential surface of the rotating body 20 so as to rotate together with the rotating body 20. The cleaning brush 25 is composed of a multi-stranded long band shape and a soft and flexible fabric so as not to damage the surface of the vehicle body when the vehicle is washed, and in particular, by using a microfiber woven fabric to further increase the washing performance.

On the other hand, the present invention is provided with a compressed air injection means that can perform a foreign material removal and water removal function by spraying compressed air in addition to the washing function by the steam.

Compressed air injection means, as shown in Figure 1 and 5 has an air supply pipe 31 disposed in the longitudinal direction in the steam supply pipe 11, the upper end of the air supply pipe 31 in the air supply pipe 31 Compressed air supply unit 33 for supplying compressed air is connected. Compressed air supply unit 33 may be configured as an air compressor that can supply compressed air. The solenoid valve 33a is installed in the air supply line of the compressed air supply unit 33 to control the supply of compressed air in the washing step.

The air supply pipe 31 is provided with an air nozzle 32 disposed at a position corresponding to the plurality of blade pieces 22 to inject compressed air, and the air nozzle 32 penetrates the steam supply pipe 11 to the outside. The compressed air is sprayed toward the blade piece 22 by being exposed to the blade.

Referring to the operation of the automatic steam car wash composed of such a configuration as follows. As shown in FIG. 3, when the solenoid valve 12a of the steam supply unit 12 is opened to supply high temperature and high pressure steam into the steam supply pipe 11, the steam nozzle disposed in the longitudinal direction of the steam supply pipe 11. Steam is strongly sprayed through (13), so that the highly viscous contaminants on the surface of the vehicle, as well as contaminants that have been stuck for a long time, can be easily removed, and the amount of washing water can be drastically reduced by using steam. The amount of generation can be greatly reduced.

Meanwhile, while the vehicle is washed by the strongly injected steam, as shown in FIG. 4, the strongly injected steam collides with the blade pieces 22 provided on the upper and lower surfaces of the rotating body 20 and rotates. Since the rotation force is applied to the entire body 20, the rotor 20 rotates around the steam supply pipe 11, and the cleaning brush 25 made of a soft and flexible fabric has a centrifugal force due to the rotation of the rotor 20. As it is in the unfolded state, it rotates to clean the vehicle without damaging the surface of the vehicle.

At this time, the bearing 21 interposed between the rotating body 20 and the steam supply pipe 11 can smoothly rotate the rotating body 20 even with a small rotational force, and the blade piece 22 is shown in FIG. 4. As inclined with respect to the injection direction of the steam as described above it can increase the washing efficiency by stronger the rotational force of the rotating body 20 when colliding with the strongly injected steam.

In addition, the wing piece 22 is covered with a cover 23 at its upper end, and as one side of the wing piece 22 colliding with steam is formed into a curved surface, the jetting force of steam is made to act on the wing piece 22 to be greater. It is possible to further increase the rotational force of the rotor 20, thereby further increasing the cleaning efficiency.

After performing the cleaning function by the steam as described above, the steam washing function can be stopped by blocking the solenoid valve 12a of the steam supply unit 12, and then the solenoid valve of the compressed air supply unit 33 as shown in FIG. When opening (33a), the compressed air is supplied to the air supply pipe 31, the compressed air is strongly injected toward the vehicle through the air nozzle 32 provided in the air supply pipe 31, steam washing for the vehicle After the function, it is possible to perform a drying function, it can also serve as a dehydration function of the washing brush (25).

The injection of compressed air through the air nozzle 32 may also be operated during steam washing. The strong jet of steam and the strong jet of compressed air together push the blade piece 22 more strongly to further increase the rotational force of the rotor 20, it is possible to further increase the cleaning efficiency of the vehicle by the cleaning brush (25). .

As described above, the present invention uses the rotational power of the rotating body 20 to perform the steam washing function without using the drive motor and the power transmission mechanism of a complicated configuration as the strong driving force of steam or steam and compressed air as the rotational power. In addition, by simplifying the configuration of the washing device 10, it is easy to manufacture and reduce the manufacturing cost, and also by reducing the water used for cleaning significantly can save the operating cost and equipment space of the wastewater treatment facility.
