Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described in detail below. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

Hereinafter, the washing value according to an embodiment of the present invention will be described.

1 shows a washing apparatus according to an embodiment of the present invention. 1, a washing apparatus 1 according to an embodiment of the present invention includes a drying frame 100, a cleaning frame 200, an air blower 300, and a main cleaning unit 400 can do.

The car wash apparatus 1 may comprise a fixed frame 10 for fixing car wash equipment. The stationary frame 10 is installed perpendicular to the paper surface, and the cleaning frame 200 and the drying frame 100, which will be described later, are connected to the stationary frame 10. The stationary frame 10 may have an inlet that is wider than the width of the commercial vehicle so that the vehicle can be drawn into the car wash area.

FIG. 2 shows a cleaning frame according to an embodiment of the present invention, and FIGS. 3 to 5 show a main cleaning part provided in the cleaning frame.

2 to 5, the cleaning frame 200 is connected to the stationary frame 10. The cleaning frame 200 can move in the horizontal direction with respect to the vehicle on the fixed frame 10 when the vehicle is stopped in the car wash zone Z. [ The cleaning frame 200 may include a horizontal portion 210 and side portions 221 and 222.

On the side portions 221 and 222 of the cleaning frame 200, a main cleaning portion 400 for spraying a cleaning fluid toward the vehicle is positioned.

The main washing unit 400 may include a rotating nozzle unit 410 for spraying the washing liquid toward the vehicle and a washing agent supplying unit 420 for spraying the washing agent toward the vehicle.

Meanwhile, in order to supply the washing liquid to the main washing unit 400, the washing apparatus 1 may include a washing liquid supplying unit (not shown). The cleaning liquid supply unit is configured to supply the fluid supplied from the fluid supply pump (not shown) to the rotating nozzle unit 410 of the main washing unit, and may be located on the upper and side portions of the washing apparatus 1. At this time, the cleaning liquid supply unit may be composed of a metal pipe capable of moving the fluid, and the material used for the pipe may be aluminum or resin in addition to metal.

The rotary nozzle unit 410 includes a body 411 connected to the cleaning liquid supply unit and rotatably connected to the cleaning liquid supply unit, a plurality of nozzles 412 which are radially connected and fixed to the body 411, ). The nozzle 412 can jet the cleaning liquid supplied from the cleaning liquid supply portion toward the vehicle. When the cleaning liquid is sprayed from the plurality of nozzles 412, the body portion 411 can rotate.

The plurality of nozzles 412 fixed to the body portion 411 can be simultaneously rotated by the rotation of the body portion 411. [ As the plurality of nozzles 412 rotate, the jetting range of the cleaning liquid jetted from the plurality of nozzles 412 becomes wider than when the nozzles are fixed. Therefore, even when the size of the vehicle is large or the shape is wide, the cleaning liquid is sprayed to a wider range, so that the washing range of the vehicle can be widened. This makes it possible to more effectively carry out car washing. Further, each nozzle can be inclined downward so that the cleaning liquid can be sprayed downward toward the vehicle.

5, each of the plurality of nozzles 412 is connected to the body portion 411, and the respective injection nozzles are arranged at a predetermined angle with respect to each other. For example, three nozzles 412 may be provided, and the nozzles 412 may surround the body 411 and be spaced apart from each other at equal angles. For example, when three nozzles 412 are provided, each nozzle may be disposed at an angle of 120 degrees with respect to one another.

A process of spraying the cleaning liquid to the vehicle by the rotary nozzle unit 410 of the main cleaning unit 400 will be described below.

The cleaning liquid is supplied to the rotary nozzle unit 410 from the cleaning liquid supply unit. The cleaning liquid supplied to the rotary nozzle unit 410 is supplied to the respective nozzles 412 through the body unit 411 and the cleaning liquid is supplied to the vehicle through the nozzles 412. At this time, the rotary nozzle unit 410 sequentially discharges the cleaning liquid while rotating with respect to the cleaning liquid supply unit by the discharge pressure of the cleaning liquid inclined in the spray direction. At this time, the cleaning liquid may be sprayed to the entire area of the vehicle while the cleaning frame 200 is moved horizontally.

For example, referring to FIG. 6, the cleaning liquid may be sprayed over the entire area of the vehicle, because the cleaning liquid is sprayed on the surface of the vehicle in an overlapping manner while oval traces are drawn on the surface of the vehicle by the rotation of the rotary nozzle unit 410.

After the cleaning liquid is sprayed from the rotary nozzle unit 410, the cleaning agent supply unit 420 is operated, and the cleaning agent is sprayed toward the vehicle. At this time, the cleaning frame 200 is horizontally moved, and the cleaning agent is sprayed to the entire area of the vehicle. The detergent may be a shampoo containing a surfactant component, a water-based detergent, or the like. The cleaning agent supply unit 420 may also supply the pressurized cleaning agent and may discharge the cleaning agent. Thereby, the cleaning agent can reach the vehicle from the cleaning agent supply part 420.

The sub-cleaning part 470 may be located on the upper part of the cleaning frame 200. The sub-cleaning portion 470 may spray fluid from the top of the cleaning frame 200 to the surface of the vehicle. To this end, the auxiliary cleaning portion 470 may be connected to the cleaning liquid supply portion. The sub-cleaning portion 470 may include at least one jetting nozzle 472. The injection nozzle 472 can inject the same cleaning liquid as the nozzle 412 of the above-described rotary nozzle unit 410 toward the vehicle.

Subsequently, the car wash apparatus 1 may include a drainage section 490 connected to the main washing section 400 at the side portions 221 and 222 of the cleaning frame 200. The drainage section may include a drain pipe 492 and an on-off valve (not shown).

The drainage unit 490 discharges a cleaning fluid such as a cleaning liquid or a cleaning agent remaining in the main cleaning unit 400 to the outside after washing. The opening of the drainage section 490 is formed to face downward. In one example, the opening of the drainage section 490 is formed toward the ground. Through the opening of the drainage section 490, a cleaning fluid such as a cleaning fluid or a cleaning agent that remains on the pipe or nozzle without being sprayed onto the vehicle is naturally discharged to the ground.

In most cases, the washing apparatus 1 is installed outdoors. In winter, a washing liquid or the like may be frozen in a pipe or a nozzle. In this case, the pipe or the nozzle may be frozen. To prevent this, it is necessary to discharge the cleaning fluid such as the cleaning fluid and the cleaning fluid remaining in the main cleaning portion 400 to the outside. This function is handled by the drainage section 490.

On the other hand, the drainage unit 490 may include an on-off valve (not shown) so that the cleaning fluid of the rotating nozzle unit 410 and the cleanser supply unit 420 of the main washing unit 400 may not flow out to the outside during washing have. That is, during the car wash, the opening / closing valve is closed so that the cleaning fluid does not flow out of the rotary nozzle unit 410 and the cleaning agent supply unit 420. On the other hand, after washing, the opening / closing valve is opened, and the cleaning fluid remaining in the pipe, the rotating nozzle part 410 and the cleaning agent supply part 420 is discharged to the outside. At this time, the cleaning fluid is discharged to the outside through the drain pipe 492 of the drain portion 490. The drain pipe 492 may be made of a metal pipe capable of moving the fluid, and the material used for the pipe may be aluminum or resin other than metal.

Figs. 7 and 8 are views showing a drying frame and an air blower, and Figs. 9 to 15 show an embodiment and modifications of an air blower.

Hereinafter, the drying frame and the air blower will be described with reference to Figs. 7 and 8. Fig. The drying frame (100) is connected to the stationary frame (10). The drying frame 100 can move in the horizontal direction with respect to the vehicle on the fixed frame 10 when the vehicle is stopped in the car wash zone Z. [ The drying frame 100 may include a horizontal portion 110 and side portions 121 and 122.

Thereby, the air blower 300 connected to the drying frame 100 can also horizontally move at the upper portion with respect to the vehicle. At this time, the air blower 300 can remove foreign matter, water and the like attached to the surface of the vehicle. This will be described later.

The drying frame 100 may include a driving unit (not shown) so that the air blower 300 can move upward and downward with respect to the ground. The driving part may be a device such as a motor, for example. Both ends of the airbag 300 are connected to the respective side portions 121 and 122 of the drying frame 100 and the driving portion is connected to the air blower 300 such that both ends of the airbag 300 are raised and lowered from the respective side portions 121 and 122 And also to both ends thereof. Thereby, the position of the air blower 300 is adjusted so that the air blower 300 is moved up and down according to the external shape of the vehicle, and the distance from the vehicle becomes constant. In addition, the air blower 300 can move in the horizontal direction by the drying frame 100. [ For example, it is possible to move toward the front of the vehicle or toward the rear of the vehicle while maintaining the distance from the vehicle surface. In one example, the air blower 300 can move between the front and rear of the vehicle. The air blower 300 removes foreign matter or moisture from the surface of the vehicle while supplying air to the surface S of the vehicle while moving in the horizontal direction.

On the other hand, depending on the external shape of the vehicle, the external appearance of the vehicle has a curvature. It is necessary to adjust the position of the air blower 300 in response to the bending. To this end, the air blower 300 includes the sensor unit 500 . The sensor unit 500 senses the outer curvature of the vehicle when horizontally moving the air blower 300 and controls the driving unit so that the air blower 300 and the vehicle can be maintained at a constant interval. That is, the air blower 300 is moved up and down in accordance with the curvature of the vehicle exterior to keep the distance between the vehicle and the air blower 300 (d in Fig. 4) constant.

The air blower 300 injects high-pressure air toward the vehicle, thereby removing foreign matter and moisture from the surface of the vehicle. For example, it is possible to remove foreign matter adhering to the surface S of the vehicle before washing by the cleaning liquid. In addition, foreign matter and moisture can be removed by spraying air onto the surface of the vehicle after spraying the cleaning liquid to the vehicle.

9 to 15, the air blower 300 includes a main body 310, a first air nozzle 311 located below the main body 310, and a second air nozzle 311 located adjacent to the first air nozzle, 2 < / RTI > air nozzle 321 as shown in FIG.

The main body 310 temporarily accommodates the high-pressure air supplied from the pump 350. That is, the high-pressure air can stay in the main body 310 until the high-pressure air is discharged to the respective lower-positioned air nozzles 311, 321. The longitudinal direction of the main body 310 may be parallel to the longitudinal direction of the horizontal portion 110 of the drying frame 100.

The first and second air nozzles 311 and 321 located below the main body 310 discharge high-pressure air to the vehicle.

9 is a view showing an air blower 300 according to an embodiment of the present invention.

Referring to FIG. 9, the first and second air nozzles 311 and 321 may be positioned in parallel with each other. In this case, the advancing directions a1 and a2 of the air discharged from the first and second air nozzles 311 and 321 may be parallel to each other. The traveling directions a1 and a2 of the respective air can form a vertical direction with the surface S of the vehicle. That is, when the first and second air nozzles 311 and 321 are perpendicular to the vehicle surface S, the traveling directions a1 and a2 of the air discharged from the first and second air nozzles 311 and 321, a2 may be parallel to each other.

10 to 11, the direction of the air discharged from the first and second air nozzles 311 and 321 may be different from each other. For example, the traveling direction a1 of the air discharged from the first air nozzle 311 is perpendicular to the surface S of the vehicle, and the traveling direction a2 of the air discharged from the second air nozzle 321, 1 > with the surface S of the vehicle. The predetermined angle? 1 may be an acute angle.

The traveling direction a2 of the air discharged from the second air nozzle 321 and the surface S of the vehicle form an acute angle 1 and the traveling direction of the air discharged from the first air nozzle 311 (a1) and the surface S of the vehicle are perpendicular to each other. The opposite is also possible.

However, depending on the direction in which the air blower 300 moves horizontally, the direction of travel of the air a1 and a2 may be different. Air is injected so as to be perpendicular to the surface S of the vehicle in front of the direction in which the air blower 300 advances and air is injected to the rear of the vehicle so as to form an acute angle with the surface S of the vehicle .

10 and 11, when the air blower 300 moves in the first direction X1, the first direction X1 of the first air nozzle 311 and the second air nozzle 321 is The air a1 injected from the first air nozzle 311 relatively in front of the vehicle is sprayed so as to be perpendicular to the surface S of the vehicle. The air a2 injected from the second air nozzle 321 located behind the first air nozzle is injected at a predetermined angle with the surface S of the vehicle. Specifically, when the vector related to the traveling direction of the air a2 emitted from the second air nozzle 321 is divided by the horizontal component F1 and the vertical component F2, the horizontal component F1 is in the first direction X1 ). That is, the moving direction of the air blower 300 and the horizontal component of the advancing direction of the emitter a2 to be inclined are directed to the same direction.

Accordingly, water or foreign matter on the vehicle surface S is primarily removed by the air a1 strongly blown from the first air nozzle, and the effect of removing water and foreign matter by the air a2 sprayed thereon I can raise it. In addition, since the air blower 300 moves in the first direction X1, the water and the foreign substances move in the first direction X1 direction by the air a2, so that the foreign substances can be discharged to the outside of the vehicle . Thereby, the cleaning and drying effect of the vehicle can be maximized.

11, the air a1 injected from the first air nozzle 311 and the air a2 injected from the second air nozzle 321 can be superimposed on each other on the surface S of the vehicle have. Specifically, FIG. 8 shows a case in which the second air nozzle 321 is inclined more toward the first air nozzle 311 than in FIG. The traveling direction a1 of the air discharged from the first air nozzle 311 is perpendicular to the surface S of the vehicle and the traveling direction a2 of the air discharged from the second air nozzle 321 is 2 at an acute angle? 2 with the surface S of the vehicle, but? 2 may be a value smaller than? 1 in FIG. That is,? 1>? 2 is satisfied. As a result, the air discharged from the first air nozzle 311 and the air discharged from the second air nozzle 321 are superimposed on each other before they reach the surface S of the vehicle, have. As a result, foreign substances attached to the surface S of the vehicle can be removed more easily, and the effect of drying the water can be enhanced. The traveling direction a2 of the air discharged from the second air nozzle 321 and the surface S of the vehicle form an acute angle 2 and the traveling direction of the air discharged from the first air nozzle 311 (a1) and the surface S of the vehicle are perpendicular to each other. The opposite is also possible. In this case as well, the traveling directions of the air a1 and a2 can be made different according to the direction in which the air blower 300 moves horizontally, as described above. Air is injected so as to be perpendicular to the surface S of the vehicle in front of the direction in which the air blower 300 advances and air is injected to the rear of the vehicle so as to form an acute angle with the surface S of the vehicle .

Fig. 12 is an example in contrast to the example shown in Fig. 10 and Fig. 9, the air a1 injected from the first air nozzle 311 and the air a2 injected from the second air nozzle 321 do not overlap with each other, The air a2 is inclined while being formed at a predetermined angle? 3 from the rear with respect to the advancing direction of the air blower 300. As shown in Fig. That is, with reference to the advancing direction of the air blower 300, the air of the second air nozzle 321 from the rear of the air a1 without overlapping with the air a1 from the first air nozzle 311, (a2) is injected. When each air a1 and a2 does not overlap each other until the respective air a1 and a2 reach the surface S of the vehicle, a vortex is formed in the space between the respective injected air a1 and a2 , The effect of removing foreign matter and cleaning may be deteriorated. That is, when foreign substances are scattered from the four sides of the vehicle S by the air a1 and the air a2 is sprayed behind the traveling direction of the air blower 300 at this time, these foreign substances are separated by the air a2 And these foreign substances will sink to the surface S of the vehicle again, so that the cleaning and drying effect is lowered.

Fig. 13 is a view showing another embodiment of the air blower 300. Fig.

13, the air a1 injected from the first air nozzle 311 and the air a2 injected from the second air nozzle 321 are respectively injected at predetermined angles As shown in FIG. At this time, the predetermined angle may be an acute angle. Specifically, when the vector related to the traveling direction of the air (a1, a2) injected from each of the air nozzles 311, 321 is divided into the horizontal components F3, F5 and the vertical components F4, F6, The horizontal components F3 and F5 may be opposite to each other.

The jetting areas of the jetted air a1 and a2 can overlap each other on the surface S of the vehicle. The superimposed air has a stronger air pressure, so that the dust on the surface of the vehicle can be removed more efficiently.

FIGS. 14 and 15 are views showing a state in which air is blown by using the air blower 300 of FIG. 14 and 15, while the air a1 injected from the first air nozzle 311 and the air a2 injected from the second air nozzle 321 are injected so as to overlap on the surface S of the vehicle , The air blower 300 moves forward or rearward of the vehicle by the main frame 100.

At this time, the main body 310 of the air blower 300 may be inclined at a predetermined angle with respect to the surface S of the vehicle. For example, as shown in FIG. 14, the air blower 300 is horizontally moved toward the first direction X1, and the main body 310 can be inclined at a predetermined angle. Specifically, by tilting the main body 310, the air a1 emitted from the first air nozzle 311 can be made perpendicular to the surface S of the vehicle. At this time, the air a2 injected from the second air nozzle 321 may be inclined at an acute angle with the surface S of the vehicle to be injected. At this time, when the vector related to the traveling direction of the air a2 is divided by the horizontal component F7 and the vertical component F8, the horizontal component F7 is set to be the first direction X1. The air a1 of the first air nozzle is sprayed while the air blower 300 moves and the air a2 of the second air nozzle is sprayed behind the air a1, Can be removed. Since the moving direction of the air blower 300 and the horizontal component F3 of the air a2 injected from the second air nozzle are the same in the first direction X1, There is an effect that the foreign substance or water on the surface can naturally escape to the outside of the vehicle.

Fig. 15 shows a case where the main body 310 of the air blower 300 moves in the direction opposite to Fig. The embodiment of Fig. 15 differs from that of Fig. 14 only in that the moving direction of the main body 310 is the second direction X2, not the first direction X1, and the air nozzles 311 and 321 The principle and effects of spraying, cleaning and drying of the air (a1, a2) to be sprayed are the same as those of the embodiment of Fig. The horizontal component F9 relating to the traveling direction of the air a1 injected from the first air nozzle 311 is in the second direction X2. The air a2 injected from the second air nozzle 321 can be perpendicular to the surface S of the vehicle.

Thus, the air blower 300 shown in Fig. 13 is configured so as to be capable of moving in the direction of tilting the main body 310, regardless of which direction the air blower 300 moves in the first direction or the second direction, The car wash effect can be obtained. Specifically, by adjusting the moving direction of the air blower 300 and the tilting direction of the main body 310, the air a1, a2 emitted from one of the air nozzles 311, And the other one of the air (a1, a2) is tilted at the back thereof, so that efficient washing can be performed. At this time, the area on the vehicle surface S on which the air (a1, a2) is sprayed is superimposed so that the strength of the air is strengthened, whereby the car wash effect can be enhanced.

Alternatively, instead of tilting the main body 310, the main body may be horizontally moved in parallel with the surface S of the vehicle, while being discharged from the first and second air nozzles 311 and 321, It is possible to adjust the discharge angle of the air. To this end, the first and second air nozzles 311 and 321 can be turned as needed. The air blower 300 may include a discharge angle adjusting unit (not shown) for the first and second air nozzles 311 and 321 to rotate the first and second air nozzles 311 and 321. The air a1 and a2 are injected so as to overlap each other as described above with reference to Figs. 11 and 12 while controlling the discharge angles of the first and second air nozzles 311 and 321, The same effect as in the above-described embodiments can be obtained by adjusting the moving direction and the jet direction of the air, and as a result, the car wash effect can be improved.

Referring again to Figures 7 and 8, in order to supply high pressure air to the air blower 300, the car wash device 1 may include a pump 350. The pump 350 sucks and pressurizes the air to produce high-pressure air. The pump 350 may be located at the top of the horizontal portion of the drying frame 100.

Meanwhile, the high pressure air generated by the pump 350 is supplied to the main body 310 of the air blower 300 through the air supply part 352. The air supply part 352 may be formed of a material such as a polymer resin such as a hose. Further, it may be formed of a material containing aluminum.

On the other hand, the main body 310 is formed with a coupling portion 315 to be coupled with the air supply portion 352. High pressure air can be supplied to the main body 310 through the coupling portion 315 and the air supply portion 352. [

The washing process by the washing apparatus 1 of the present invention will be described as follows.

First, when the vehicle to be washed is parked in the car wash zone Z defined by the fixed frame 10 of the car wash device 1, the car wash device is ready to wash.

The cleaning fluid supply unit supplies the cleaning fluid to the main cleaning unit 400 and the auxiliary cleaning unit 470. The cleaning frame 200 in which the main cleaning unit 400 and the auxiliary cleaning unit 470 are positioned moves in the horizontal direction.

First, high-pressure cleaning liquid is injected into the vehicle from the rotary nozzle unit 410 of the main cleaning unit 400. At this time, the injection nozzle 472 of the sub-cleaning unit 470 can also spray the cleaning liquid at a high pressure toward the vehicle. Thereby, all the surfaces of the vehicle are cleaned with the cleaning liquid.

In the meantime, as the cleaning frame 200 moves and the cleaning agent supply part 420 is activated, the cleaning agent is injected toward the vehicle through the cleaning agent supply part 420. Then, the vehicle is cleaned with a cleaning agent.

Subsequently, the cleaning frame 200 is moved again, and the high-pressure cleaning liquid is sprayed onto the vehicle from the spray nozzle 472 of the rotary nozzle unit 410 and the auxiliary cleaning unit 470, . In the process, optionally, a brush can be used to assist the car wash.

Thereafter, the drying frame 100 and the air blower 300 may be operated to remove the cleaning liquid remaining on the surface of the vehicle. That is, the cleaning liquid remaining on the surface of the vehicle can be removed by the high-pressure air discharged from the air blower 300.

Specifically, air is pressurized by the pump 350 to be high-pressure air, and high-pressure air is supplied to the air blower 300. [ The drying frame 100 connected to the air blower 300 moves in the horizontal direction of the vehicle. Simultaneously with the movement, the sensor unit 500 senses the outer curvature of the vehicle and operates the driving unit to maintain the air blower 300 and the surface of the vehicle at a predetermined interval.

High-pressure air is discharged from the first air nozzle 311 and the second air nozzle 321 of the air blower 300 to dry the vehicle surface. That is, the discharged air removes foreign matter and moisture from the surface of the vehicle. At this time, the high-pressure air discharged from the first air nozzle 311 can be discharged to the outside of the vehicle by the high-pressure air discharged from the second air nozzle 321.

In addition, since a high drying effect can be obtained by adjusting the angle of the air to be sprayed by making the air (a1, a2) to be sprayed double, the surface of the vehicle is separately cleaned by using a cloth or cloth, There is no need to remove water.

In the above-described embodiment, the cleaning liquid is sprayed when the vehicle enters the car wash equipment. However, the air can be sprayed by using the air blower before spraying the cleaning liquid. In this case, it is possible to primarily remove foreign matter or dust adhering to the surface of the vehicle, and then wash the vehicle using the cleaning fluid. Thereafter, the washing process can be completed through a drying operation using an air blower.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
