Abstract

PURPOSE:To eliminate an ill effect such as frosting and freezing in the cold weather in a short time and continuously by providing hot wires intrinsically in the glass lower part including the area part with which an automatic window wiper device is brought into contact in its stop state, and heating this part. CONSTITUTION:A front windshield is intrinsically provided with hot wires in the glass in a range 6 shown by oblique lines in such a way that the hot wire part exists including the stop position of a window wiper device 2. A current is applied to a heating wire by a switch from a power circuit mounted at a vehicle so as to heat the lower part of the front windshield rapidly to perform the removal of snow, frost, and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a front window of, for example, an automobile.

[Conventional technology]

For example, in order to ensure the safety and visibility of drivers and passengers in the front windows of automobiles, there is a structure that uses an automatic window cleaning device to remove torpedoes adhering to the outside surface of the window during rain, snow, etc. In order to prevent deterioration of transparency due to clouding caused by water vapor condensation,
Some devices eliminate this by blowing warm air using the heat generated by the engine. In addition, in order to eliminate the above-mentioned obstacles, for the rear window, an automatic window cleaning device is installed on the outside of the window in the same way as the front window, and on the inside, the glass is heated using a glass containing a hot wire. A method has been adopted to prevent fogging and ensure visibility by heating the area.

[Problem to be solved by the invention]

As mentioned above, securing visibility is an essential condition for ensuring the safety of passengers while driving a car, etc., and the reliability of equipment related to this is essential. The fact that tower users want these facilities to be improved requires no explanation.

Particularly during the cold season, a problem is freezing of the front windshield due to frost. For this reason, the driver has to warm up the engine after starting the engine to generate warm air and wait for the ice to melt by heating the front windshield. At the same time, the driver and others have to come out of the car and remove the ice using a spatula, etc. It is also necessary to do some work. Furthermore, the rubber portion of the automatic window cleaning device may also be stuck to the window surface due to ice formation, and there is often a risk of damage to the device if the device is operated without being aware of this. The effects of snowfall are similar to the above, especially when driving in the snow, even if the windshield is heated with hot air, the accumulated electricity cannot be removed and accumulates over time, which in turn has a negative effect on window cleaning equipment and reduces visibility. It becomes.

The present invention has been made to solve the above-mentioned problems, and it is possible to quickly warm up the front window of a car in cold weather, reduce the various effects, and ensure the visibility of the passengers, thereby ensuring safety. The purpose is to improve the

[Means to solve the problem]

The structure of the front window according to the present invention is such that when the automatic window cleaning device is in a stopped state, the heating element is attached to the lower part of the glass where the window and the rubber blades of the device come into contact within an area that does not obstruct the driver's view. It is made to be internalized and heated.

[Effect]

In vehicles using this front window, power is supplied from the power supply circuit mounted on the vehicle using a switch to operate the heating wire. That is, it is similar to the heating wire operating circuit for a rear window conventionally used in passenger cars.

〔Example〕

FIG. 1 is a conceptual plan view of the present invention applied to a passenger car, and FIG. 2 is a side view thereof.

In both figures, 1 is the front window glass, 2 is the automatic window cleaning device (usually called a wiper), 3 is the rear window glass, and 4 is the rear automatic window cleaning device, which is used in most passenger cars in recent years. has been adopted. 5 is a heating wire built into the rear window, which heats the rear window.

6 shows the area in which the heat rays are included in the front windshield in the present invention with diagonal lines. Within this range, the visibility from the driver's line of sight as shown in Figure 2 will hardly decrease compared to the conventional one. It is also possible to arrange the strips in an array, but since it does not affect visibility as mentioned above, it is possible to use a strip-shaped heating element, which is an effective method for front windows that require rapid heating. obtain.

[Effects of the Invention] ゛As is clear from the above explanation, by interposing a heating element in the front windshield, the present invention can improve the heating of the glass, which previously depended only on the method of blowing hot air. It is possible to quickly and continuously eliminate the harmful effects of cold weather, frost, snowfall, freezing, dew condensation, etc., which not only improves driver safety but also reduces maintenance costs. It can provide great benefits.
