The present invention relates to a method and a device for washing a door type car wash, and more particularly, a method for washing a car wash and drying in a reciprocating section of a round trip section of a door type car wash, allowing a car wash to be completed within a short time; Relates to a device.

The door car washes the car body by rotating and contacting the cleaning brush while spraying water and detergent or wax while reciprocating a certain section of the car to clean the car body, and then injecting high pressure air to remove moisture on the car body. In general, as shown in Figure 1, the door-shaped main body (1) having an opening of a size that the vehicle can enter and exit is installed so as to move the power on the rail (2, 2 ') installed side by side on the ground, The height and wheels of the vehicle body are detected by beam sensor arrays 3 and 3 'installed at the opening of the main body 1, and water, detergent, wax, etc. are sprayed through a sprayer installed on the ceiling side of the opening although not shown in the drawing. The washing process is performed by rotating and contacting the washing top brush 4a, the side brushes 4b and 4b ', and the rocker brushes 4c and 4c', and then the drying top air nozzle 5a and the side air nozzles. 5b, 5b ') of high pressure through By spraying a group performs a drying process.

Regarding the structure, arrangement, and operation of the spray nozzle for the cleaning process, the cleaning brush, and the nozzles for the drying process, Patent Publication Nos. 1993-0004782 and 1993-0004786 and 1995-0010517, Registered Patent Publication No. 0150430 And 0117939, and Japanese Patent Laid-Open Publication No. 1999-0069042 and the like.

The door washers are programmed to select various car wash courses such as water car wash, detergent car wash, wax car wash, detergent wax car wash, etc. by operating the operation panel 6 attached to the front of the body. This is usually done during one or two rounds of car wash. Of these, when looking at the precession of the car wash course performed in the 1 round trip transfer section by section, it is divided into a traveling washing process (S21) and a double-drying drying process (S22) as shown in FIG. As shown in FIG. 3A, the washing process (S21) is a washing brush (4a, 4b) that is rotated while spraying detergent or wax with water or water to the vehicle while the car wash body (1) moves the ascending section. 4b ', 4c, 4c') contact the car body to clean the car body. And the return-drying step (S22) drives the blower mounted inside the main body (not shown) while the car wash body (1) moves the return section after returning washing step, that is, return to the original position, from the blower The high pressure air is discharged through the drying air nozzles 5a, 5b and 5b 'to remove moisture from the vehicle body.

Among the prior arts listed above, Patent No. 0150430 discloses a first cleaning process in which the brush is sprayed while spraying water or detergent in the first travel section to increase the washing effect, while foaming and spraying the detergent in the first recovery section. A car wash method has been proposed, which consists of a second cleaning process for brushing, a wax coating process for spraying water and wax in the second travel section, and a drying process for spraying air in the second return section. This method is a good way to increase the car wash effect, but it takes a lot of time since you have to make two round trips. Therefore, there is a problem that it is difficult to meet a lot of car wash demand.

To meet large car wash demands in a short time, the car wash time should be shortened. In short, the washing time can be shortened by increasing the round trip speed of the door-type car wash, but the faster the car wash speed, the worse the precession condition. By the way, the washing process in the conventional door-type car washes must be carried out over at least one round trip transfer section, and furthermore, since both washing and drying must maintain an appropriate speed, the washing time was limited.

In addition, among the prior arts listed, Patent Publication No. 0157939 discloses a technique for increasing the drying effect by adjusting the air injection direction of the vehicle top drying nozzle according to the inclination of the vehicle body, which is described below. Will also be used.

On the other hand, in the conventional door car wash as a way to facilitate the entry of the next car wash, as shown in Figure 4 in the form of a drive through (drive through) to let the vehicle entering the car wash position through the car wash after the end of the car wash. It is often installed, in which case more space is required, taking into account the minimum radius at which the vehicle rotates past the car wash.

An object of the present invention is to shorten the washing time in the door-type car washes to meet the demand of more car washes, and also to efficiently install and operate in a narrow place by using the installation space, during one round trip section of the door-shaped car wash It is to provide a car wash method and apparatus capable of completing both the above-described washing process and drying process in the royal section.

First car wash performs the 1 king washing / drying process (S91), which performs washing and drying at the same time in the return section of the car wash section, and transfers only the car body to its original position in the return section. The car wash is completed at (S92). Here, the first king washing / drying process (S91) is performed by spraying the water not shown first through an injector (not shown) while the car wash body 11 moves the reciprocating section of the reciprocating section for the vehicle stopped at the car washing position as shown in FIG. The upper air nozzle 15a located behind the cleaning brushes while spraying detergent or wax with water or rotating the cleaning brush including the upper brush 14a in contact with the vehicle body and performing the conventional washing process. Drying nozzles are detected at the above-described beam sensor array 13 and at the drying start position (front end cover position) of the vehicle, which is a drying position calculated by the controller 50 of FIG. Once reached, the blower and its air nozzle (not shown) are automatically activated. At this time, the waterproof barrier film 16 is lifted as the upper air nozzle 15a is lifted to block the water splashed by the upper slush 14a which is rotated from the front. In this way, after washing and drying are carried out during the journey, only the car wash is quickly returned without any washing operation during the return.

Next, Figure 11 is a flow chart of the process when the 1.5 king wash was selected as another washing method of the present invention. 1.5-Wash car wash is a car wash course that performs two cleaning processes for vehicles with relatively high pollution levels. It is the first to brush and apply detergent or wax together with water or water in the reciprocal section of one round trip of the car wash. After the cleaning process (S111) and the second washing step (S112) to wash or shower once more in the return section of the one round-trip transfer section (S112), and then the drying step (only drying in the second travel section) S113) is performed, and the car wash is quickly returned to the second looping section.

The types of car washes and the process progress states of the car washes that can be implemented in the car wash apparatus of the present invention are as follows.

Car Wash Course 1 royal car wash 1Current car wash 1 king wax car wash 1 king dry 1.5 Car Wash 1.5 King's Car Wash 1.5 king wax car wash 1 round trip Royal line water ● ● ● ● ● ● Detergent ● ● ● ● Wax ● brush ● ● ● ● ● Air nozzle ● ● ● ● ● ● Double water ● ● ● Detergent Wax ● brush ● ● ● Air nozzle ● 2 round trips Royal line water Detergent Wax brush Air nozzle ● ● ● Double water Detergent Wax brush Air nozzle

That is, the present invention is carried out the drying process in each car wash course in the royal section, and only the car wash is transported to the original position in the state in which all the washing and drying is finished in the last return section. Therefore, it is possible to move the car wash quickly in the last double section, thus reducing the car wash time.

12 is a flowchart showing an operation of adjusting the air spraying direction of the upper air nozzle in accordance with the height of the vehicle body during the drying process as a method of increasing the drying effect during the drying process in the royal section, and FIG. 13 is a diagram illustrating the operation. It is. As shown in these figures, once the drying process starts, while operating the air cylinder 30 shown in FIG. 7 described above, while lowering the above-mentioned upper air nozzle to the predetermined lower limit position (step S121), the upper air nozzle ( The flaps 25 and 25 'of 15a are tilted in one step direction to be inclined toward the front of the car washing advance direction (step S122). At the predetermined lower limit position, the respective flashing states are determined from the signals of the rising beam sensor 22a and the falling beam sensor 22b (step S123). If the rising beam is determined to be in the OFF state, the nozzle is raised (step S123 '). If the rising beam is not in the OFF state, that is, in the ON state, the blinking state of the falling beam is judged (step S124), and when the falling beam is in the OFF state, the rising beam is turned ON while the nozzle is lowered (step S124 '). At the same time, by stopping the nozzle (step S125) when the falling beam is turned off, the position of the upper air nozzle 15a is dried while maintaining an appropriate minimum distance from the vehicle body.

On the other hand, while the car wash moves through the travel section, it is determined whether the dry position of the upper air nozzle 15a is the start position of the rear windshield of the vehicle according to the data detected and calculated by the sensor beam array described above (step S126). If the flap is tilted in two stages (step S126 ') so that the air spraying direction is vertically downward, and if the position is determined as the trunk end position (step S127), the flap is tilted in three stages in which the flap is directed backward in the advancing direction (step S127). Step S127 ') to increase the drying effect on the rear glass and the trunk rear portion of the weak part of the vehicle.

When it is determined that the vehicle is at the end position of the trailing section (step S128), the nozzle is raised to the initial position to be stored and the drying operation is completed.

Figure 14 shows the installation specifications of the car wash apparatus having a new arrangement for carrying out the car wash method according to the present invention. According to the present invention, as shown in this figure, since the car wash main body 11 is completely washed and dried in the travel section, the car wash completed with the car wash main body 11 at the end of the travel section is pulled forward. You can leave or go straight or turn left. In this case, it can be seen that the installation space can be shortened by about 4.5 m compared with the conventional (Fig. 4).

As described through the above embodiments, the method and apparatus for washing a door-type car wash according to the present invention can greatly shorten the overall washing time by completing both washing and drying in the reciprocating section of the car wash. Therefore, while the car wash demand can be handled, the same washing time will provide the effect of much higher car wash effect.

In addition, according to the present invention, it is possible to significantly reduce the installation space of the door-shaped car wash is provided with an advantage that can be installed and operated in a small area.
