Description

[Detailed Description of the Invention] The present invention relates to an automatic car wash installed in business offices such as gas stations and car washes, with an improved air outlet.

Conventionally, when washing a vehicle using an automatic car wash machine, the vehicle is first washed with an aqueous solution, and then the aqueous solution adhering to the vehicle is blown off and dried using air pressure discharged from an air outlet. However, as the automatic car wash moves, the aqueous solution is pushed out horizontally as shown in Figure 6, blowing off the water droplets, but water droplets remain all over the vehicle, and especially on cloudy days, the water droplets do not dry for hours. After an employee washes a car, they must wipe off any water droplets with a dry cloth. In addition, when customers are crowded and there is a shortage of manpower, when customers are in a hurry to wash their cars, they are unable to wipe the water droplets on the body and can only wipe the glass surface with a dry cloth. This results in a decrease in For this reason, business offices that always strive to provide service have to hire more employees than necessary, resulting in high personnel costs.

In recent years, there are automatic car wash machines that perform everything from car washing to complete drying, but these are expensive and cannot be purchased unless you have plenty of funds, and if the usage rate is not high, it will not be profitable. There were problems such as it being extremely difficult to do so.

The present invention was developed to solve the above problem, and by improving the air outlet of automatic car wash machines so that the amount of air discharged differs depending on the position, water droplets remaining on the vehicle can be reduced. To provide an automatic car wash machine which reduces the amount of washing and requires no manual labor after washing, and which requires very little maintenance and management cost.

Embodiments of the present invention will be described below based on the drawings. Reference numeral 1 indicates a gate-shaped automatic car wash machine main body.
2 and 3 are inner wall portions 1a on both sides of the automatic car wash main body 1.
4 is an air outlet for drying provided on the side, and its shape is approximately an inverted trapezoid that gradually widens as it goes upwards (see Figure 2). The shape of the air discharge port 4 is formed so that it becomes gradually narrower toward the center. Its shape is, for example, approximately eight-shaped (see FIG. 3). Further, the discharge amount of the air discharge ports 2, 3, and 4 is formed to be different depending on each position. In addition, the air discharge ports 2 and 3 of the conventional automatic car wash machine main body 1 are equipped with right triangular plates.
A plate material in the shape of a flat isosceles triangle may be fixed to the air discharge port 4 to adjust the discharge amount to a desired change.

Next, to explain the operation of the present invention, the air discharge ports 2 and 3 are formed in a substantially inverted trapezoidal shape that gradually widens as they go upward, so the amount of air discharged increases as they go upward. do. Therefore, the air starts to flow downward due to the air attached to the side surface of the vehicle 5 from the upper side. Furthermore, the air discharged downward from the air outlet 4 suspended from the ceiling portion 1b makes it easier for the water droplets to flow downward. Therefore, when the automatic car wash main body 1 moves to dry the side surface of the vehicle 5, the air flow is directed downward at an appropriate angle as shown in FIG. 5, and the amount of remaining water droplets is extremely reduced. If we compare the remaining amount of water droplets with that of a car washed in a conventional automatic car wash, we first set the conditions as a cloudy day where water droplets do not dry easily, and the process of washing the car is the same. Experimental results show that the amount of remaining water droplets with this product is approximately 30-50% higher than with conventional products.
Diminished. Therefore, there is no need to wipe water droplets adhering to the vehicle 5 even on a cloudy day.

In addition, since the shape of the air discharge port 4 is formed in a substantially eight-shape shape that gradually becomes narrower toward the center, the amount of air discharge increases toward both ends of the air discharge port 4. For this reason, the flow of drying air discharged onto the top surface of the vehicle 5 is different from the conventional one, and although the details have not been elucidated, if you compare the amount of water droplets remaining on the top surface of the vehicle 5 with the conventional one, is 20
The remaining amount of water droplets was approximately 1.9%, and in the case of the present invention, almost no water droplets remained. The shape of the air outlet 4 was obtained from experiments with various shapes.

In this way, the present invention has air discharge ports 2 and 3 for drying provided on both inner wall portions 1a of the automatic car wash main body 1.
The shape of the air discharge port 4 is formed into a substantially inverted trapezoidal shape that gradually widens as it goes upward, and the shape of the air discharge port 4 suspended from the ceiling portion 1b is formed so that it becomes gradually narrower as it goes toward the center. This makes it easy for the aqueous solution that adheres to the vehicle 5 to fall off, and the amount of water droplets remaining is extremely small, especially on cloudy days, so there is no need for manpower after washing the car, and water droplets on the body can be easily removed when a customer in a hurry washes the car. Since there is no need to wipe the area, there is no deterioration in service, and furthermore, the number of employees can be kept to a minimum to keep labor costs down, and maintenance costs are extremely low. Moreover, the price of an automatic car wash machine is 2 air outlets,
Since there is no change in the internal structure except for changing the shape of parts 3 and 4, it can be purchased at the same price as the conventional product, and has great practical effects.
