Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a car washing machine of the same type, and more specifically, a car washing machine that washes a car with a rotating brush and blows air from a drying nozzle onto the car body to remove water droplets that have adhered to the car body after washing. This relates to a gate-type car wash machine that is designed to blow dry.

[Prior Art] A gate-type car wash machine uses a rotating brush to wash a car, and then blows air from a drying nozzle onto the car body to blow away the remaining wash water droplets and dry the car body. Already known.

By the way, in this type of conventional gate-type car wash machine, the opening of the drying nozzle's air outlet is provided facing almost vertically downward, and it is located close to a protrusion such as a side mirror protruding from the car body surface. In order to avoid collision between the drying nozzle and the vehicle body, a certain distance is preset between the lowering point of the drying nozzle and the vehicle body. Therefore, the air is blown at a certain distance, and the cleaning water droplets that remain on the car body are scattered and blown away, so they re-adhere to the dry car body. Furthermore, since there is a gap between the drying nozzle and the car body, the ability to blow away the cleaning water droplets is relatively weak before the air reaches the car body, making it difficult to carry out the drying process efficiently. was there.

[Object of the Invention] The present invention has been developed in view of the problems of the prior art described above, and its purpose is to provide a similar type of car wash that can effectively dry washing water droplets on the car body. The aim is to provide the opportunity.

[Structure of the Invention] In the gate-type car wash machine according to the present invention, the tip of the drying nozzle serving as the air outlet is formed of a flexible member.

[Operations and Effects of the Invention] Therefore, even if the nozzle is brought sufficiently close to the car body and collides with a part of the car body, the nozzle escapes due to the flexible member, so the part of the car body is not damaged and the air is not wasted. The nozzle can be sprayed directly onto the vehicle body, and the nozzle can be oriented so that the cleaning water droplets are always blown away in the forward direction where they have not yet entered the drying process. As a result, cleaning water droplets are no longer blown away and reattached to parts of the car body that have completed the drying process, eliminating the need for manual wiping of residual water droplets after the drying process, and significantly improving drying efficiency. It is possible to improve the efficiency of drying work.

[Preferred Embodiment] When carrying out the present invention, the flexible member at the tip of the drying nozzle is preferably in the shape of a bellows tube made of a soft material such as rubber. Moreover, instead of such a bellows tube-like structure, a plate-like structure made of soft rubber or the like may be hung on one side so as to be able to swing freely. It is even more preferable to provide a control unit such as a wing.

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

FIGS. 1 and 2 show an example of the overall structure of a gate-type car wash machine in which the present invention is implemented. Inside the gate-type frame 1, air is sprayed onto a vehicle body (not shown), and cleaning water droplets are sprayed onto the vehicle body (not shown). Top nozzle 2 and side nozzle 3 are drying nozzles for blowing and drying the car body, and washing water (
A cleaning water nozzle 4 for spraying (or water mixed with detergent) or finishing wax, a top brush 5 for mainly brushing the roof of the vehicle, and a rocker brush 6 for mainly brushing around the tires and the bottom of the doors of the vehicle. , a side brush 7 that mainly brushes the front and rear surfaces and sides of the vehicle, and a vehicle height sensor 10 that detects the vehicle height are provided, and the vehicle height sensor 10 is an ultrasonic type,
Various methods such as optical type, electromagnetic wave type, and contact type can be applied.

The frame body 1 is provided with an operation switch 8, and when the operation switch 8 is turned on, the frame body 1 travels back and forth on the rails 9 based on a preset program, and during that time, a predetermined movement of the vehicle is performed. Cleaning work is now being carried out.

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 a lifting mechanism 12 that operates based on a detection signal from a vehicle height sensor 10, and serves as an air outlet during the drying process. The tip 17 is positioned at a constant 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 the parallel link 11 and fed back to the elevating depression 12.

The top nozzle 2 includes a main body 16 and a tip 17 as an outlet, and the main body 16 is connected to a vertical support 14.
is connected to the parallel link 11 via the bellows tube 1.
5 to a blower (not shown) which is an air supply source.

The tip 17 of the top nozzle 2, which serves as an air outlet, is formed of a flexible member made of soft rubber, for example, and is shown in FIG. This is a first embodiment in which a tip portion 17 is formed in contact with each other. In this case, if the side edge in the moving direction of the top nozzle 2, that is, in the direction of the arrow shown in the figure, is formed to be slightly shorter than the opposite side edge of the tip edge 18 of the bellows-tubular tip portion 17, dry air can be The blowing direction can be more effectively guided in the direction of the vehicle body C before entering the drying process.

FIG. 4 shows a second embodiment in which a tip portion 17 is formed by attaching a plate member to the main body portion 16 so as to be able to swing freely.

That is, the opening edge 19 of the main body 16, which is located on the side opposite to the moving direction of the top nozzle 2, that is, the direction of the arrow shown in the figure, is attached to the opening edge 19 by a pivoting means 20 or an appropriate attachment means. The tip portion 17 is formed by swingably attaching a plate material made of rubber or the like,
The presence of this tip 17 makes it possible to reliably guide the blowing direction of the drying air in the direction of the vehicle body C before entering the drying process. FIG. 5 shows the second embodiment shown in FIG. 4, in which a wind direction IIIt[21 is disposed inside the main body 16 so that the blowing direction of the air can be more reliably controlled via the angle changing device 22. This is another embodiment in which the air blowing direction is forcibly regulated to the right of the car body C before entering the drying process by the presence of the wind direction control blade 21, and the air blown to the car body C is Since it is possible to prevent the cleaning water droplets from scattering in all directions, it is possible to effectively prevent the cleaning water droplets from re-adhering to the vehicle body C after the drying process. Note that the tip of the side nozzle 3 is also formed of a flexible member.

Since the present invention is configured in this manner, when air is blown onto the vehicle body C by the top nozzle 2 in the drying process,
The tip portion 17 following the main body portion 16 can be brought close to the vehicle body C, and since the tip portion 17 is formed using a flexible member such as soft rubber, the tip portion 17 protrudes from the vehicle body C1. Even if it comes into contact with protrusions such as side mirrors, it can flex flexibly and conform to the shape of the protrusions, so the drying process is smooth while the nozzle is moved without damaging these protrusions. can be completed.

[Effect 1] As explained above, according to the present invention, air can be directly blown from a close distance to the vehicle body in a fixed direction, so the blowing force of the cleaning water droplets is large, and the drying process can be simplified. It is possible to prevent the washing water droplets from re-adhering to the car body as much as possible, and the drying process can be carried out smoothly and efficiently without damaging protrusions such as side mirrors even if they come into contact with them. It can dry the car body.
