Wind is blown toward the car 9 from each nozzle 5.6, thereby drying water droplets after the car has been washed.

Further, the car wash machine is configured to be operated using an operation surface (panel) 1o provided on the front side of the car wash main body 1.

However, in the conventional car wash machine, in the final drying process, the position and angle of the side nozzle 5 are constant, so the direction of the wind blowing from the side nozzle 5 is constant, and the car 9 It is not possible to perform effective drying according to the shape of the vehicle body, and especially when the vehicle type of car 9 is a wagon, there is a problem that the upper part of the window is not sufficiently dried.

The present invention is intended to solve the above-mentioned problems, and aims to provide a car wash machine that can sufficiently dry any type of car or wagon.

Means for Solving the Problems In order to solve the above problems, the car wash machine of the present invention is provided with a side nozzle that blows air out to the side of the car being washed, a blower device that supplies air to the side nozzle, and a running device. The gate-shaped car wash machine body includes a vehicle height detection means for detecting the vehicle height of the car, an actuation means for tilting the side nozzle rearward about a fulcrum provided at the lower end, and a rearward movement of the side nozzle. a position detecting means for detecting an inclination angle, and when the vehicle height detecting means is driven to determine that the vehicle is a wagon when the car wash main body is traveling on the outward journey, the blower device is driven to detect the vehicle height. A control means is provided for driving the actuating means to tilt the side nozzle rearward at a predetermined angle without confirming the detection signal of the position detecting means during the return journey in which the vehicle is dried by blowing air from the side nozzles. It is something that

Effect: When it is determined that it is a car or a wagon according to the above configuration,
When drying a car, by driving the actuating means to tilt the side nozzle backward at a predetermined angle (hereinafter referred to as trailing), it is possible to blow wind from diagonally downward onto the side of the car, which is different from conventional methods. The dry condition of the upper part of the window of the wagon car, which was not in good dry condition, is now in good condition.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings. Components that are the same as those of the conventional example shown in FIGS. 6 and 7 are designated by the same reference numerals, and their explanation will be omitted.

FIG. 1 is a block diagram of a control system of a car wash machine according to an embodiment of the present invention.

The control system of the car wash machine is largely built into the car wash main body 1.
The control device 12 includes an input/output section 13, a control section 14, and a storage section 15, the operation surface 1o, a sensor system, a drive system, and a power source 17. Detection signals from sensor systems such as the sensor 11, the position control sensor 18 of the side nozzle 5' shown in FIG. , a drive system including a traveling device 16 for moving the car wash main body 1 and the like is controlled to control the overall operation of the car wash main body 1.

Further, as shown in FIG. 2, the side nozzle 5' is connected to a fulcrum 5' provided at the lower end by an air cylinder 2o which is an operating means.
A position control sensor consisting of an encoder that counts the number of gears 5° to be detected attached to the side nozzle 5', which is a position detection means, and the angle of the trailing direction of this side nozzle 5' is a position detection means. 18, side nozzle 5'
The side limit position of is detected by a position detection switch 19 consisting of a limit switch serving as a position detection means.

Furthermore, in the case of car 9 or a wagon, the vehicle height detection signal of car 9 from the sonic sensor 11 is continuous at a high level as shown in FIG. can be determined.

Hereinafter, a method of drying the car 9 using the side nozzle 5'' by the control device 12, which is the gist of the present invention, will be explained with reference to the flow chart shown in FIG.

When the car wash main body 1 is running on the outward journey, washing the car 9 using the side brush 2, top brush 3, and rocker brush 4,
As described above, it is assumed that the sonic sensor 11 is driven to detect the body shape of the car 9 and to determine whether the car 9 is a vehicle type or a wagon.

First, confirm that the mode is the final stage of drying (Step-1), then confirm whether it is the car type of car 9 or a wagon (Step-2), and confirm that it is a wagon. 5 As shown in Figure (a), air cylinder 2
0, the position detection switch 19 operates, that is, the side nozzle 5 is pulled until it reaches the side limit position, and the side nozzle 5 is moved backward (Step-3, Step-4).
, the side nozzle 5 is blocked (Step-5), and the blower device 7 is driven (Step-6).

If it is confirmed in step-2 that there is no wagon, the side nozzle 5' is not moved as shown in FIG. 5(b), and the blower device 7 is driven in step-6.

Then, when the conditions for reversing are confirmed (step = 7),
A reverse command is output to the traveling device 16 (step-8).

If you move backward in this state and confirm that you have arrived at the origin (
Step-9), output a stop command to the traveling device 16; Step-10), drive the air cylinder 20 and use the detection signal of the position control sensor 18 as a feedback signal to move the side nozzle 5° as shown in FIG. 5(b). The process is tilted forward to the original tilt angle (step-11, step-12), then the blower device 7 is stopped (step-13), and the process ends.

By driving the blower device 7 in this way, the nozzle 5'
During the return trip drying process where the car is dried by blowing air,
When it is determined that it is a car 9 or a wagon, the side nozzle 5
By moving the windshield behind, it is possible to blow wind from diagonally downward onto the sides of the wagon, thereby improving the drying condition of the upper part of the window of the wagon, which has traditionally been poorly dry.

Note that the rear inclination angle of the site nozzle 5° can be set depending on the vehicle width of the car 9 and other vehicle types. It can be set to a predetermined backward oblique angle.

As described in detail, according to the present invention, when it is determined that the car is a car or a standard car, when the car is drying, the actuating means is driven to tilt the side nozzle rearward, thereby drying the car. By blowing air diagonally from below to the sides, it is possible to improve the drying condition of the upper part of the window of a wagon car, which has traditionally been dry.
