DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portal type car washer for washing a car.

[0002]

2. Description of the Related Art A gate-type car washer reciprocates a car wash machine provided on a rail, and performs a plurality of car washes in a single car wash, such as a water washing process, a shampoo process, a shampoo washing process, and a drying process. The process is executed. In this water washing process, water is sprayed from the liquid injection nozzle fixed to the car wash machine body to wash the car.In the shampoo process, shampoo is injected from the liquid spray nozzle fixed to the car wash machine body, and the car wash brush is rotated to wash the car. In the shampoo washing process, the shampoo is washed out by spraying water from the liquid injection nozzle fixed to the car wash machine body, and in the drying process, the air injection nozzle is raised and lowered to bring it closer to the car body, and the car is dried by blowing water droplets with air ing. As described above, since the conventional liquid injection nozzle is fixed to the car wash machine main body, not only the cleaning performance is low, but also the cleaning liquid scatters outside the vehicle body, and much of the cleaning liquid is wasted.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a gate capable of effectively applying a cleaning liquid ejected from a liquid injection nozzle to a vehicle body to enhance the cleaning performance and minimizing the amount of the cleaning liquid scattered outside the vehicle body.

In the provided portal type car washer, a liquid injection nozzle is provided in addition to the air injection nozzle, and the liquid injection nozzle is connected to the storage tank via a pump, so that the cleaning liquid can be injected from a position close to the vehicle body. As a result, the car washing ability with the washing liquid is increased. Further, the amount of the cleaning liquid scattered outside the vehicle body can be reduced, and the cleaning liquid is not wasted.

The liquid ejecting nozzles are provided on the front and rear surfaces of the air ejecting nozzle, and each of the liquid ejecting nozzles is mounted obliquely downward, so that liquid is selectively ejected from each of the liquid ejecting nozzles.

Next, the operation will be described with reference to the flow charts of FIGS. When the vehicle is stopped at the center of the rails 2 and 2 and the start switch of the keyboard 12 is pressed and a start signal is input to the control device 27 (ST1 in FIG. 6), the control device 27 executes the first step of car washing (ST2 in FIG. 6). ).

That is, the control device 27 sends a forward rotation signal to the movement motor 28 for rotating the wheels 11 to send the liquid injection nozzles 6, 1
A drive signal is output to a drive motor 32 that drives a pump that sends water to the nozzle 0, and a drive signal is output to a drive motor 23 that moves up and down the air injection nozzle 9 on the upper surface. Then, the car wash machine body 3 moves forward, the air injection nozzle 9 moves up and down, and the liquid injection nozzle 6,
Water is injected from 10 and the car is washed. Air injection nozzle 9
When the control device 27 receives the detection signal of the vehicle sensor 26, the control device 27 rotates the drive motor 23 in the normal and reverse directions, and moves the air injection nozzle 9 to a position close to the optimum distance without contacting the vehicle body to be washed.

The first step of this car wash is liquid injection (ST1 in FIG. 7), and the car wash machine body 3 moves forward (S7 in FIG. 7).
T2), the controller 27 opens the on-off valve 17 (ST in FIG. 7).
3). And the water sent through the hose 19
The liquid is injected from a liquid injection nozzle 10 provided on the front surface of the air injection nozzle 9 via an on-off valve 17 and a pipe 15. Car washing is performed in this manner, and the air injection nozzle 9 moves horizontally in the car washing on the roof portion of the car (ST4 in FIG. 7), and the air injection nozzle 9 moves downward at the rear end of the car (FIG. 7).
ST5), the control device 27 closes the on-off valve 17 and opens the on-off valve 18 (ST6 in FIG. 7). This time, water is injected from the liquid injection nozzle 10 provided on the rear surface of the air injection nozzle 9. When the first step is completed and the liquid injection is completed (ST7 in FIG. 7), the control device 27
8 is closed (FIG. 7, ST8).

When the first step of car washing is completed (ST3 in FIG. 6), the control device 27 executes the second step of car washing (ST4 in FIG. 6).

That is, the control device 27 sends a reverse rotation signal to the moving motor 28 for rotating the wheels 11 to send the liquid jet nozzles 6, 1, 2.
Driving motor 3 for driving pump to send shampoo to zero
3, a drive signal is output to a drive motor 23 that moves up and down the air injection nozzle 9, and a drive signal is output to drive motors 29 and 30 that drive the car wash brush 5 on the side and the car wash brush 8 on the top. Then, the car washer body 3 moves forward, the air injection nozzle 9 moves up and down, shampoo is injected from the liquid injection nozzles 6 and 10, and the car wash brushes 5 and 8 move while rotating to wash the car. As in the first step of car washing, the air injection nozzle 9 is moved up and down to the optimum distance without contacting the vehicle body to be washed with the detection signal of the car sensor 26 in the same manner as in the first step of washing the car. .

The second step of this car washing is liquid injection (ST1 in FIG. 7), and the car washing machine main body 3 moves backward (S7 in FIG. 7).
T2), the control device 27 opens the on-off valve 18 (ST in FIG. 7).
9). Then, the shampoo sent through the hose 19 is injected from the liquid injection nozzle 10 provided on the rear surface of the air injection nozzle 9 via the on-off valve 18 and the pipe 16. Car washing is performed in this way, and the air injection nozzle 9 moves horizontally in the car washing on the roof of the car (ST1 in FIG. 7).
0), when the air injection nozzle 9 descends at the tip of the vehicle (ST11 in FIG. 7), the control device 27 closes the on-off valve 18 and opens the on-off valve 17 (ST12 in FIG. 7). This time, water is injected from the liquid injection nozzle 10 provided on the front surface of the air injection nozzle 9. When the second step is completed and the liquid injection is completed (ST7 in FIG. 7), the control device 27 closes the on-off valve 18 (ST8 in FIG. 7).

When the second step of car washing is completed (ST5 in FIG. 6), the control device 27 executes the third step of car washing (ST6 and ST4 in FIG. 6). The third step of this car wash is
This is a shampoo washing step, which is substantially the same as the first step of car washing, and a description thereof will be omitted.

When the third step of car washing is completed (ST5 in FIG. 6), the control device 27 executes the fourth step of car washing (ST6 and ST4 in FIG. 6).

That is, the control device 27 sends a reverse rotation signal to the movement motor 28 for rotating the wheels 11,
A drive signal is output to a blower 31 that sends air to the nozzle 9, and a drive signal is output to a drive motor 23 that moves up and down the air injection nozzle 9. Then, the car wash machine body 3 moves backward and the air injection nozzle 9
Ascends and descends while injecting air, and blows off the water droplets on the body to dry. In the same manner as described above, the air injection nozzle 9 is raised and lowered by receiving the detection signal of the vehicle sensor 26 and approaching the optimum distance without the air injection nozzle 9 coming into contact with the vehicle body to be washed.

When all the car washing steps are completed (ST6 in FIG. 6), the control device 27 ends the control.

As described above, since the liquid injection nozzle 10 is provided adjacent to the air injection nozzle 9 and is brought close to the optimum distance without contacting the vehicle body to be washed, the washing effect by the washing liquid is enhanced, and No waste. Further, since the opening / closing valve 17 or 18 is selectively opened / closed according to the car washing state, as shown in FIG. 8, the washing liquid is sprayed from an optimum position for the car.

In this embodiment, water and shampoo are jetted from a common liquid jet nozzle, but a dedicated liquid jet nozzle may be provided for each. Also,
If a dedicated liquid injection nozzle is provided, only the water injection nozzle that has a higher cleaning effect when approaching the vehicle body is attached to the air injection nozzle, and the other liquid injection nozzles may be fixed to the car wash machine body. .
