The present invention relates to the anti-fog structure of the vehicle glass to prevent the occurrence of obstacles in driving due to the fog on the windshield of the vehicle.

As is well known, during the rainy days of driving a conventional car or in winter, the humidity inside the car becomes high and the temperature difference between the outside and the car is generated, so that the side glass and the rear glass of the driver's seat and the passenger seat are frosted. As a result, the vision is obscured, and thus, such a fog is a problem that causes obstacles in safe driving.

And, as described above, if the tea glass is frosted, you need to prepare a towel, etc., and then wipe it off one by one, which will cause inconvenience and safety problems, and turn on the heater to prevent fog. The air conditioner may be turned on, but there is a limit to remove the fog, and in the spring or autumn, there is a problem such as causing discomfort due to the haptic temperature to remove the fog by turning on the heater or the air conditioner.

In order to solve the above problems, the present invention is to install the remaining glass except for one of the glass of the car as a double glass, one glass is installed as a single glass, the temperature difference between the outside and the car the most severe The purpose of the present invention is to provide an anti-fog structure of automobile glass which prevents fogging from occurring on the remaining double glass side by concentrating a large amount of moisture on the glass side.

Figure 1 shows a schematic plan view of a motor vehicle employing the anti-fog structure of the automotive glass of the present invention for achieving this object.

Referring to FIG. 1, the front windshield 1 of the vehicle, the left and right windshields 2 and 3 on the side front, and the rear windshield 4 are double-glazed glass 6 having a waterproof structure in which an air layer 5 is interposed in the center. It consists of 7), and the left and right glass windows 8 and 9 of the side back are comprised by the one glass 10.

When the automobile windshield is constructed in this way, the front windshield 1, the rear windshield 4, and the side front windshield 2, 3 made of double glass 6, 7 have an insulating effect due to the air layer 5 in the middle. Since the heat by the cold outside air is transferred to the inside of the vehicle is lowered, the windshield 8, 9 of the rear side is composed of a single glass 10, so the cold outside air is affected first.

Accordingly, the humidity 11 generated in the car on a rainy day or in winter is concentrated in the rear side windows 8 and 9 that receive the most sensitive external temperature, and the remaining windows 1, 2 and 3. (4) will not get moisture.

Figure 2 illustrates this principle.

That is, if the temperature of the outside air of the car is t1 ° C, since the front window 1 has a double-insulated glass window structure, the heat of the outside temperature (t1 ° C) in contact with the outer glass 6 of the front window 1 is insulated and The in-vehicle temperature (t2 ° C) in contact with the glass (7) maintains a sufficiently high temperature (t1 ° C t2 ° C), and this temperature relationship is the remaining side front windshield (2) (3) and the rear windshield, which is a double-window structure The same holds true for (4).

However, the outside air temperature (t1 ° C.) in contact with the outside of the glass windows 8 and 9 at the rear of the side composed of one glass 10 is the temperature in the car in contact with the interior of the glass rear windows 8 and 9 which is one glass. As soon as (t3 ° C) is lowered, the temperature relationship between the temperature (t2 ° C) (t3 ° C) and the outside temperature (t1 ° C) in the vehicle becomes (t1 ° C) (t3 ° C) (t2 ° C).

Accordingly, the temperature t2 ° C (t3 ° C) in the vehicle is t2 ° C t3 ° C, and the internal temperature (t2 ° C) of the front windshield 1, the side front windshield 2, 3, and the rear windshield 4 which are double glass windows The internal temperature (t3 ° C.) of the side rear windows 8 and 9 becomes significantly lower.

Therefore, the moisture 11 in the vehicle is concentrated in the inner surface of the rear side rear windows 8 and 9 at the lowest temperature, and hardly forms on the remaining windows 1, 2, 3 and 4.

As described above, the anti-fog structure of the automobile glass of the present invention concentrates moisture formed on the automobile windshield on rainy days or high humidity days on the windshield of the position that does not interfere with driving, Prevents condensation on the windows of the driver's left and right sides (side miller) and rear (room miller).

Therefore, it is possible to ensure safe driving, and can alleviate the inconvenience of removing the moisture on the window with a towel, and there is an effect that can prevent the operation of unnecessary air conditioning or heater in particular.

Claims (1)

The front windshield (1) of the vehicle, the left and right windshields (2) and (3) in front of the side, and the rear windshield (4) consist of double-glazed glass (6, 7) with a waterproof structure with an air layer (5) in the center. The left and right windshields 8 and 9 of the rear side are composed of a single glass 10 so that moisture is concentrated in a single pane of glass, thereby ensuring the visibility of the remaining double glass windows. Resistant structure.
