Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a gate-type car wash machine that blows dry air from a drying m nozzle onto the car body after washing the car to blow away wash water droplets attached to the car body and dry the car body. Regarding J-ru.

[Prior art 1] A gate-type washing machine that washes a car using a rotating brush or a jet of washing water and then blows dry air into the car body from a drying nozzle to blow away the washing water droplets attached to the car body and dry it. Are known.

By the way, the drying nozzle in a car wash is usually installed in a substantially vertical direction, so the washing water droplets are blown off in both directions after washing the car body, and then reattached to the dried car body. Or, at the face end of the car,
Since the air is ejected towards the ground and does not hit the car, the air is wasted and cannot sufficiently blow away water droplets attached to the front and rear ends of the car. Therefore, the drying effect is low,
There is a problem in that residual cleaning water droplets must be wiped off after drying TPiI.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems, and its object is to provide a gate-type car wash machine that improves the drying effect.

[Structure of the Invention] The gate-type car wash machine according to the present invention is provided with a drying nozzle whose air blowing angle to the car body is variable according to the shape of the car body so that the blown washing water droplets are directed in one direction.

[Operations and Effects of the Invention] Therefore, the cleaning water droplets are blown away in a fixed direction, that is, in the direction before drying, and are not blown off to the part of the car body after drying. Furthermore, even if the J3 is located at the front and rear ends of the car, the air hits the car body and efficiently prevents water droplets from being blown away. As a result, the drying effect is greatly improved and it becomes unnecessary to wipe off residual water droplets after the drying process.

[Preferred Embodiment 1] When carrying out the present invention, the air outlet of the drying nozzle may be configured to rotate, or the drying nozzle may be sprayed at different angles. ! Two air outlets may be provided, or the entire drying nozzle may be blown twice. Further, when carrying out the present invention, it is preferable that the drying nozzle is moved up and down based on the output signal of the vehicle height sensor, and the air outlet is positioned at a certain distance from the surface of the vehicle body. In this way, the drying effect can be further improved.

[Example] The present invention will be described in detail below with reference to the drawings.

An example of a gate-type car wash machine in which the present invention is implemented is shown in FIG. 1 J3 and FIG. 2, and various devices are arranged within the gate-shaped frame 1.

That is, inside the frame 1, dry air is blown onto the vehicle surface.
A drying nozzle, that is, a top nozzle 2 and a side nozzle 3, for drying the car body after washing, and a washing water nozzle for spraying washing water (or water mixed with detergent) or finishing wax to wash the car body surface. 4, a top brush 5 that mainly brushes the roots of the vehicle, a rocker brush 6 that mainly brushes around the tires of the vehicle and the bottom of the doors, a side brush 7 that mainly brushes the front and rear surfaces and sides of the vehicle, and a top brush 5 that mainly brushes the roots of the vehicle. An ultrasonic, previous generation, electromagnetic wave, or contact type vehicle height sensor 10 is provided to detect the vehicle height.

The frame body 1 is provided with an operation switch 8, and by turning on the operation switch 8, the frame body 1 moves back and forth on the rail 9 based on a preset program, and during that time, the frame body 1 moves back and forth on the rail 9. Predetermined cleaning work is performed.

The top nozzle 2 is attached to the front part of the frame body 1 via a parallel link 11, and is raised and lowered by an elevating mechanism 12 that operates based on a detection signal from a vehicle height sensor 10, and the air outlet 15 is raised and lowered during the drying process. is positioned at a certain distance from the surface of the vehicle body. Note that the height of the top nozzle 2 is detected by a rotary encoder 13 linked to a parallel link 11 and fed back to the stomach drop structure 12.

As shown in FIGS. 3 and 4, the top nozzle 2 includes a main body 14 and an outlet 15.

Its body 14 is connected to the above via vertical supports 16.

It is connected to a parallel link 11, and is also connected via a bellows pipe 17 to a near blower (not shown) which is a dry air source. The air outlet 15 is provided with a bellows pipe 18 at the bottom of the main body 14.
An arm 20 with a gear 19 fixedly attached to the upper end is attached to the side. This gear 19
is engaged with a gear r22 fixed to the output shaft of a drive motor 21 provided on the side of the main body 14, and the drive motor 2
1, the arm 20 rotates around the gear 19, and the air outlet 15 is rotated both forward and backward as shown by the one-dot chain line or the two-dot chain line. As shown in FIG. 5, the rotation angle α of the air outlet 15 can be changed according to the shape of the vehicle body by a control device (not shown) so that the blown cleaning water droplets are directed in a fixed direction, that is, in the direction before drying. ing. Car body A
On the other hand, when the air outlet 15 moves rearward together with the frame 1 as shown by the arrow, if we explain that the counterclockwise direction from the vertical line is plus and the clockwise direction is minus, then α-80'' is applied to the rear end of the vehicle body. ~90° (a>.

For the trunk, α-15° to 25° (b).

For the rear window, α = 30° to 60° (C),
, for the roof, α -15° ~ 20'' (d >; for the front window, α = 0° ~ -15° (e
). α-15° to -25° (f
). For the front end of the vehicle, α = -15° to -25° (

Next, the effect will be explained.

The dry air blown out from the air outlet 15 is blown against the car body A as shown in FIG. In other words, the straw is blown in the direction of movement of the air outlet, that is, in the direction before drying, and not in the direction after drying. Further, at the beginning of the drying process, the air outlet faces the ball (a) in a horizontal direction and hits the rear of the vehicle body, so that the lower part of the bumper, etc. can also be dried. Therefore, the drying effect is greatly improved, and there is no need to wipe off residual washing water droplets after the drying process.

FIG. 6 shows another embodiment of the present invention, in which the main body 14 and the outlet 15 are rotatably connected by a hinge 30 instead of the bellows tube 18, one end of the air cylinder 31 is connected to the main body, and the other end is the outlet. 15, and the direction of the air outlet 15 is changed by driving the air cylinder 31 to expand and contract. FIG. 7 shows still another embodiment of the present invention, in which three air outlets 24a to 24c with different air outlet angles are integrally formed in the main body 23 of the top nozzle 2, and each of them is opened and closed by an opening/closing mechanism 25a to 25c. This is an example in which on-off valves 26a to 26c are provided, and dry air is selectively blown out from one outlet. In this embodiment, the air outlet 24a is used at position ia in FIG. 5, the air outlet 24b is used at positions c, d, e, and It has the same effect as the example.

FIG. 8 shows still another embodiment of the present invention, in which a nozzle rotation cylinder 27 in which the entire nozzles 1 to 3 are interposed in the lower link of the parallel link 11 is extended and contracted to rotate. Note that 28 is a spring that cushions the impact when the top nozzle 2 hits the vehicle body. This embodiment also has the same effects as the embodiment shown in FIG.

As explained above, according to the present invention, a drying nozzle is provided in which the spraying angle to the car body is variable according to the shape of the car body so that the blown washing water droplets are directed in a certain direction. blown forward.
