Technical Field
The present invention relates to a nozzle reversing device of a brushless automatic car washer, and more particularly, to a nozzle reversing device of a brushless automatic car washer, which can continuously reverse a nozzle without interruption, thereby preventing stains on a surface of a vehicle, and can reverse the nozzle at a high speed, thereby increasing a car washing speed, suppressing a flow of a connection hose supplying washing water to the nozzle, and preventing the connection hose from being twisted or damaged.
Background
As shown in fig. 1, an automatic car washer is a device for automatically cleaning the appearance of a vehicle, and generally includes a gate pole type for cleaning the vehicle while the car washer body 1 reciprocates along a rail provided on a bottom surface, and a tunnel type for cleaning the vehicle while the vehicle passes through the inside of the car washer body in one direction by means of a transfer device.
Such an automatic car washer is provided with a washing water nozzle for spraying washing water onto a body, the spraying of the washing water removes various contaminants such as soil or sand on the surface of a vehicle at a time, and then removes the contaminants by wiping the surface of the vehicle with a brushing device at a second time, and after the contaminants are finally removed by spraying washing water using the washing water nozzle, automatic washing is completed by removing moisture from the surface of the vehicle using a drying device.
However, the conventional automatic car washer as described above has a disadvantage in that the contaminants on the surface of the vehicle cannot be completely removed only by simply uniformly spraying water in the process of removing the contaminants once using the washing water, and in such a state, if the process of secondarily removing the contaminants using the brush unit is performed, the contaminants remaining on the surface of the vehicle are rubbed against the surface of the vehicle by the brush unit, thereby causing minute scratches on the surface of the vehicle.
Therefore, in recent years, a brushless automatic car washer has been developed, which sprays washing water with high pressure using a nozzle without a brush device, thereby completely removing contaminants on the surface of a vehicle using the spraying pressure of the washing water.
Accordingly, in the case of the brushless automatic car washer, in order to improve the washing performance, the function and performance of the nozzle for spraying the washing water at a high pressure are important.
Therefore, in the prior art, the technical development is mainly performed in a direction of increasing the ejection pressure of the nozzles, and a plurality of nozzles are installed for quick cleaning.
However, the brushless automatic car washer of the related art has a disadvantage in that contaminants separated from the surface of the vehicle by the washing water are not easily flowed down together with the washing water and remain on the surface of the vehicle because a plurality of nozzles are fixedly installed at predetermined intervals.
In other words, when the washing water is sprayed at high pressure from the nozzles fixedly provided at predetermined intervals, if the vehicle passes through the car washer body, the spray pattern of the washing water becomes a linear pattern in the lateral direction with respect to the vehicle.
Therefore, the foreign substances separated from the surface of the vehicle by the washing water are not flowed under the vehicle, but are continuously pushed out in the lateral direction according to the spray pattern which is in a linear state in the lateral direction, and finally remain on the rear side surface of the vehicle, thereby having a disadvantage that the vehicle cannot be cleaned.
The washing water is sprayed from the nozzle in a conical shape with respect to the nozzle.
In other words, the apex of the conical state becomes a nozzle, and the bottom surface of the conical state becomes a spray area where the washing water actually contacts the surface of the vehicle, and at this time, the center of the spray area corresponding to the conical bottom surface is easy to remove the contaminants on the surface of the vehicle because the spray pressure of the washing water is strong, and on the contrary, the spray pressure toward the edge of the spray area is weakened so that the contaminants are not easily removed, so that there is a disadvantage in that stains are generated due to the difference in the degree of removal of the contaminants.
In the conventional brushless automatic car washer, in order to prevent the generation of stains due to the deviation of the injection pressure of the washing water as described above, when a plurality of nozzles are installed at predetermined intervals, the injection areas of the washing water injected from each nozzle are partially overlapped, and thus, the design is performed so as to minimize the generation of stains due to the deviation of the injection pressure.
Nevertheless, it is not easy to prevent the generation of stains due to the deviation of the spray pressure of the washing water, and recently, a nozzle reversing device of a brushless automatic car washer has been developed, which reverses a nozzle up and down while spraying the washing water from the nozzle.
That is, by turning the nozzle upside down using the turning device, the spray pattern of the washing water sprayed on the surface of the vehicle is formed in a zigzag pattern, so that the contaminants separated from the surface of the vehicle more easily flow from the surface of the vehicle to the lower side, while the generation of stains due to the deviation of the spray pressure of the washing water can be prevented.
However, the conventional nozzle inverting apparatus inverts a plurality of nozzles using a cylinder so that the inversion speed is slow, and thus it is inevitable to move the vehicle at a low speed in order to uniformly spray wash water sprayed from the nozzles that are inverted at a low speed to the surface of the vehicle, thereby having a disadvantage of reducing the washing speed.
Since the faster the car washing speed of the automatic car washer, more cars can be washed in a prescribed time, the car washing speed is directly related to productivity and profitability in the standpoint of the owner who operates the automatic car washer, and thus the slower the car washing speed is a very serious disadvantage.
In addition, the conventional nozzle reversing device reverses by using the cylinder, and a time delay required for pressure control occurs while the piston rod is repeatedly charged into and discharged from the cylinder, so that a phenomenon in which the piston rod stops at the top dead center and the bottom dead center for a short time occurs.
Therefore, when the temporary stop phenomenon of the cylinder is generated as described above, as shown in fig. 2, the nozzle is temporarily stopped at the home position during the running of the vehicle, and the spray pattern of the washing water is in a straight line pattern a in the lateral direction, so that there is a disadvantage in that a part of contaminants remains on the surface of the vehicle while being squeezed out in the lateral direction.
In addition, since a temporary stop phenomenon of the nozzle occurs, there is a disadvantage in that stains are generated due to deviation of the spray pressure of the washing water.
In addition, in the conventional nozzle inverting apparatus, the connection hose connected to the nozzle is deteriorated while repeatedly flowing in the process of inverting the nozzle, and thus there are disadvantages in that water leakage due to cracks occurs or the connection hose is not able to withstand high pressure and is broken when twisting occurs.

The nozzle overturning device of the brushless automatic car washer of the invention utilizes the cam to overturn the nozzle during automatic car washing, so that pollutants washed by washing water and the washing water rapidly flow down from the surface of a car together, thereby having the effect of preventing the pollutants from remaining and washing the car more cleanly.
Further, in the process of inverting the nozzle using the cam, a phenomenon of temporary stop of the nozzle is prevented, so that there is an effect in that stains due to deviation of water pressure are prevented from being generated on the surface of the vehicle.
In addition, the turnover speed of the nozzle is made fast, so that even if the proceeding speed of the vehicle is increased in the automatic car washing, the washing water is uniformly sprayed on the surface of the vehicle, so that the car can be cleanly washed, thereby having an effect of shortening the car washing time.
Further, at the time of the inversion operation of the nozzle, the flow of the connection hose supplying the washing water to the nozzle is suppressed, thereby having an effect of preventing damage due to twisting or breaking of the connection hose, or the like.
