Abstract

PROBLEM TO BE SOLVED: To remove waterdrops and the like stuck to a windshield by utilizing compressed air and wind pressure in traveling. SOLUTION: This is a device that removes those of frost, snow and water droplet stuck to a windshield 6 of an automobile and so on. When two air wipers 1 and 2 are attached to be windshield 6, waterdrops are flowing into the rearward by dint of wind pressure during running and compressed air. In order to raise the effectively of these air wipers, an oil film is removed away to reduce an extent of friction on a glass surface, and the form of a nozzle and setting position are tried to do at each car type. During travel of a vehicle in time of a rainfall, the wind pressure from an air intake in front of a bonnet 5 and the compressed air from an air compressor 4 are blown out from a lower part of the windshield 6 up to the upper part, whereby waterdrops are flowing the rearward. Since effectiveness is brought into full play for the securness of a visual field in high-speed running in time of raining and thereby safety driving is performable, a good effect is well promoted to an accident prevention.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air wiper for removing water droplets or the like adhering to a windshield of an automobile or the like using compressed air or wind pressure during traveling.

[0002]

2. Description of the Related Art A conventional wiper removes water droplets by moving a rubber blade in contact with glass in a semicircular shape by a motor. Therefore, dust adheres to the rubber blade, or when the rubber is deteriorated, water droplets cannot be removed cleanly, or the rubber is liable to be deteriorated, so that the rubber blade must be replaced frequently.

[0003]

In the conventional wiper, when the rubber blade is deteriorated or dust adheres, water droplets remain on the windshield, resulting in poor visibility and hindering safe driving. In addition, the rubber blade is liable to deteriorate, so the rubber blade must be replaced frequently, which has a disadvantage of increasing the maintenance cost.

[0004]

In order to achieve the above object, wind pressure during traveling is used instead of a rubber blade. We have found that it is only necessary to remove water droplets using compressed air, and even if rubber painting deteriorates, water droplets etc. remaining on the glass surface can be removed with an air wiper, so the cost for blade replacement is reduced. .

[0005]

When the vehicle is running during rainfall, the water drops flow backward by blowing out the compressed air created by the air intake at the front of the hood and the air compressor from the bottom to the top of the windshield.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to implement the present invention, when an air wiper is attached to a windshield, water droplets flow backward due to wind pressure and compressed air during traveling. In order to reduce friction, it is necessary to take an oil film and try the nozzle shape and mounting position for each vehicle type.

[0007]

The present invention is effective in securing the visibility of high-speed traveling in rainy weather and can be driven safely, thereby improving the effect of preventing accidents. In addition, the number of replacements of the rubber blade is reduced, so that labor and maintenance costs are reduced, and it is economical. further,
Defrosting icy glass is easy if hot air is allowed to flow.
