The present invention relates to a car washer that is made to dry.
[0002]
[Prior art]
In the conventional car washing machine, it is widely known that the drying is performed by blowing air to a vehicle body surface using a blower (that is, water droplets remaining on the vehicle body surface are removed). The drying apparatus used has a problem that the operating noise of the blower during the drying is large.
[0003]
Therefore, in place of such a conventional drying technique, the drying is performed by forming water into a film and applying the water to a water-repellent body surface (that is, water droplets remaining on the body surface are converted into a water flow flowing down from the body surface). A technique of draining the vehicle body surface in association with each other has also been proposed (for example, see Patent Document 1).

[0021]
The traveling frame 1 is provided with a vehicle height sensor 40, which detects the upper surface position of the vehicle to be cleaned.
[0022]
Next, the operation of the present embodiment will be described.
[0023]
First, the case where the vehicle V to be cleaned has the trunk T will be described with reference to FIGS.
[0024]
As shown by a solid line in FIG. 6A, the traveling frame 1 is stopped at the start position on the left end of the traveling rails 6, 6, and the vehicle V is stopped at a predetermined position between the traveling rails 6, 6. Start car wash with the condition.
[0025]
When car washing starts, the traveling frame 1 starts traveling forward (rightward in the figure) from the start position. During the forward traveling, the top brush 21 and the side brushes 22, 22 are rotated while washing water is sprayed from the washing water injection device 23 onto the vehicle body surface of the vehicle V, and the vehicle body surface is brushed and washed. In addition, rinsing water is injected from the rinsing water injection device 24 onto the brushed and washed body surface to rinse the body surface. Note that the water discharge device 16 is held at the upper limit position during the forward traveling. Each time the traveling frame 1 travels forward by a unit distance, the vehicle height sensor 40 detects the upper surface position of the vehicle V to be cleaned. Then, when the traveling frame 1 reaches the right end of the traveling rails 6, 6, the traveling of the traveling frame 1 is stopped, the washing water is jetted from the washing water jetting device 23, and the rinsing water is jetted from the rinsing water jetting device 24. The injection is stopped, the rotation of the top brush 21 and the side brushes 22, 22 is stopped, the top brush 21 is raised and held at the upper limit position, and the side brushes 22, 22 are opened and moved to the limit position. Hold.
[0026]
Next, the traveling frame 1 starts the backward traveling (leftward traveling). Then, as shown by 16A in FIG. 6B, when the water discharge device 16 reaches the windshield F of the vehicle V, the traveling frame 1 stops traveling, and the solenoid valve 36 is opened. Water is discharged downward from the discharge port 32 of the water discharge device 16, and the electromagnetic valve 37 is opened to inject air downward from the first air injection device 17. Then, the elevating motor 11 is driven to descend, and the water discharge device 16 and the first air injection device 17 are lowered.
[0027]
When the water discharge device 16 approaches the windshield F of the vehicle V to a predetermined distance, the elevation motor 11 stops based on the upper surface position of the vehicle V detected by the vehicle height sensor 40 during the forward traveling of the traveling frame 1. Then, the traveling frame 1 starts re-traveling. At the time of this re-running, the water discharge device 16 moves up and down based on the upper surface position of the vehicle V detected by the vehicle height sensor 40 during the forward running of the traveling frame 1 so that the water discharge device 16 follows the upper surface shape of the vehicle V. The motor 11 is controlled to move downward and to move upward.
[0028]
During such rerunning of the traveling frame 1, the water discharged from the discharge port 32 of the water discharging device 16 becomes a continuous plate-shaped water flow as shown in FIGS. Falls almost vertically on the ceiling surface.
[0029]
Here, the water flow discharged from the discharge port 32 will be described. The water discharged from the discharge port 32 becomes a thin plate-shaped water flow (that is, a water film) that is not water droplets but continuous. The water is discharged so as to reach the ceiling surface, and is discharged at a flow rate at which the water flow hitting the ceiling surface does not scatter in the form of water droplets. Water is discharged from the discharge port 32 in a similar manner also on a trunk surface and a bonnet surface described later.
[0030]
Then, the water dropped on the ceiling surface of the vehicle V forms a continuous water layer 50 from the right end to the left end of the ceiling surface, as shown in FIG. Then, the water layer 50 is divided into right and left by the air flow injected from the first air injection device 17, as shown in FIG. By being divided into the left and right, the ceiling surface covered with the water layer 50 in the above is exposed to the air layer. Then, the right edge 50A of the water layer 50 divided by the air flow moves toward the right end of the ceiling surface with a low height without leaving a puddle due to the surface tension of water and the action of gravity. Further, the left edge 50B of the water layer 50 divided by the air flow moves toward the left end of the ceiling surface having a low height without leaving a puddle by the action of surface tension of water and gravity. As a result, the ceiling surface is drained well, and the ceiling surface dries without leaving a puddle. FIG. 8 shows a state in which the water discharge device 16 and the first air injection device 17 have advanced toward the rear end of the vehicle V from FIG.
[0031]
When air is not injected from the first air injection device 17, a puddle remains at the center of the ceiling surface in the vehicle width direction as shown in FIG.
[0032]
On the trunk surface, as shown in FIG. 10, the edge 50C of the water layer 50 does not leave a puddle toward the rear end of the lower trunk surface due to the surface tension of water and the action of gravity. Moving. As a result, the trunk surface is drained well, and the trunk surface dries without leaving a puddle.
[0033]
Next, when the water discharge device 16 passes through the rear end of the vehicle V as indicated by 16B in FIG. 6B, the traveling of the traveling frame 1 is stopped, and the solenoid valves 36 and 37 are closed to close the water. The discharge of water from the discharge device 16 and the injection of air from the first air injection device 17 are stopped.
[0034]
Next, after the water discharge device 16 is held at the upper limit position, the traveling frame 1 starts re-start traveling. When the water discharge device 16 reaches the same position on the windshield F of the vehicle V as indicated by 16A in FIG. 6B, as indicated by 16C in FIG. The frame 1 stops running, and the solenoid valve 36 opens to discharge water from the discharge port 32 of the water discharge device 16. Then, the elevating motor 11 is driven to descend, and the water discharge device 16 and the first air injection device 17 are lowered.
[0035]
When the water discharge device 16 approaches the windshield F of the vehicle V to a predetermined distance, the elevation motor 11 stops based on the upper surface position of the vehicle V detected by the vehicle height sensor 40 during the forward traveling of the traveling frame 1. Then, the traveling frame 1 starts the second return traveling. Then, at the time of the second re-run, the water discharge device 16 is based on the upper surface position of the vehicle V detected by the vehicle height sensor 40 during the forward traveling of the traveling frame 1 so that the water discharge device 16 follows the upper surface shape of the vehicle V. As a result, the lifting motor 11 is controlled to be lowered and driven upward.
[0036]
At the time of the second re-running of the traveling frame 1, on the bonnet surface, as shown in FIG. 11, the edge 50D of the water layer 50 has a low height due to the surface tension of water and the action of gravity. Move toward without leaving a puddle. As a result, drainage of the bonnet surface is performed well, and the bonnet surface dries without leaving a puddle.
[0037]
Next, when the traveling frame 1 reaches the start position, the traveling frame 1 stops traveling, and the electromagnetic valve 36 closes to stop discharging water from the water discharging device 16. Then, the water discharge device 16 moves up to the upper limit position.
[0038]
In the above operation, the drying operation of drying the upper surface of the vehicle body by blowing air from the top nozzle 7 onto the upper surface of the vehicle V is not performed, and the drying operation by the top nozzle 7 is performed as described above. Next, a drying operation using the water discharged from the water discharging device 16 is performed.
[0039]
Next, a case where the vehicle V to be cleaned does not have the trunk T will be described with reference to FIG.
[0040]
Similarly to the case where the vehicle V has the trunk T, the top brush 21 and the side brushes 22, 22 are rotated by injecting the washing water from the washing water spraying device 23 to the vehicle body surface with the forward traveling of the traveling frame 1. Brushing and washing the body surface. Further, rinsing water is injected from the rinsing water injection device 24 to the brushed and washed body surface to rinse the body surface. In this case, the water discharge device 16 is held at the upper limit position during the forward movement.
[0041]
Each time the traveling frame 1 travels a unit distance, the vehicle height sensor 40 detects the upper surface position of the vehicle V. Then, when the traveling frame 1 reaches the right end of the traveling rails 6, 6, the traveling of the traveling frame 1 is stopped, the washing water is jetted from the washing water jetting device 23, and the rinsing water is jetted from the rinsing water jetting device 24. Stop injection and. Further, the rotation of the top brush 21 and the side brushes 22 and 22 is stopped, the top brush 21 is raised to the upper limit position and held, and the side brushes 22 and 22 are opened and moved to the open limit position and held.
[0042]
Next, the electromagnetic valve 36 is opened to discharge water from the discharge port 32 of the water discharge device 16, and the electromagnetic valve 38 is opened to inject air from the second air injection device 18. Then, the elevation motor 11 is driven to descend, and the water discharge device 16 and the second air injection device 18 are lowered. Then, when the water discharge device 16 reaches the lower limit position, the traveling frame 1 starts the backward traveling.
[0043]
At the time of this return traveling, the elevation motor 11 is controlled based on the upper surface position of the vehicle V detected by the vehicle height sensor 40 during the forward traveling of the traveling frame 1 so that the water discharge device 16 follows the upper surface shape of the vehicle V. The downward drive control and the upward drive control are performed. When the traveling frame 1 returns, the ceiling surface and the bonnet surface are dried by the water discharged from the discharge port 32 of the water discharge device 6 in the same manner as in the case where the vehicle V has the trunk T. In the above, the ceiling surface is well drained by the air injected from the second air injection device 18, and the ceiling surface is dried without leaving a puddle.
[0044]
When the vehicle V does not have the trunk T, the “front end of the vehicle” in FIGS. 7 and 8 is the “rear end of the vehicle”, and the “rear end of the vehicle” is the “front end of the vehicle”. Side ".
[0045]
The reason why the operation method is changed depending on the presence or absence of the trunk T will be described. Since the tract surface is lower at the rear end than at the front end, it is better to move the water discharge device 16 from the front end to the rear end. This is because the surface has a good drying effect.
[0046]
Next, a second embodiment of the present invention will be described with reference to FIGS.
[0047]
In the second embodiment, a water discharge device 16 'having a different structure from the water discharge device 16 of the above embodiment is used, and the other structure is the same as that of the above embodiment.
[0048]

This is the same as the lifting control.
[0051]
Next, the operation of the water discharged from the water discharge device 16 'will be described.
[0052]
When the solenoid valve 36 is opened, water is discharged from the circular discharge port 51 as shown in FIG. The water discharged from the circular discharge port 51 becomes a continuous columnar water flow and falls on the upper surface of the vehicle V. Then, the water that has fallen on the upper surface of the vehicle body of the vehicle V forms a water layer 50 on the upper surface of the vehicle body similar to that of the above-described embodiment. As a result, the upper surface of the vehicle body is well drained, and the upper surface of the vehicle body is effectively dried, as in the above-described embodiment.
[0053]
In addition, from the circular discharge port 51, the discharged water is not a droplet but a continuous cylindrical water flow, and is discharged so as to reach the ceiling surface of the vehicle V. In addition, the water flow hitting the ceiling surface is It is discharged at a flow rate that does not scatter in the form of water droplets. The water flow hitting the upper surface of the vehicle body spreads on the upper surface of the vehicle body, and forms a continuous water layer 50 in the left-right direction, that is, in the vehicle width direction of the vehicle V.
[0054]
