Abstract

PURPOSE:To blow away a water drop at rainy time so as to remove the water drop on a total glass surface by blowing high speed air hit toward the glass surface from a nozzle. CONSTITUTION:High speed air is blown hit toward a glass surface 2 from an air nozzle 1 approximately in parallel (internal angle about 90 deg.), and by performing inversion rotary motion while blowing away a water drop at rain time, the water drop in a total glass surface is removed. Here for hitting the high speed air uniformly toward the glass surface 2 from the air nozzle 1, a discharge port 14 of the nozzle 1 is formed in an elliptical shape. An angle and a distance relating to the glass surface 2 of the air nozzle 1 are changed matched with a car speed. That is, the internal angle 3 is increased at high speed time and decreased at low speed time. Further, an amount of air and an inversion rotational amount of the nozzle 1 are adjusted to match with an amount of rain. That is, the amount of air (air speed) is increased to increase a wiping speed when a large amount of rain falls.

Description

DETAILED DESCRIPTION OF THE INVENTION - Industrial Application Field The present invention relates to front and rear window wipers for automobiles.

・Conventional technology Conventional wiper technology uses a rubber wiper blade and a metal wiper arm to rub against the glass surface to remove water droplets. However, its removal ability was not perfect. Depending on the shape of the window, parts of the window where water droplets could not be removed obstructed visibility. Also, the wipers themselves were obstructing visibility.

Problems to be Solved by the Invention To remove water droplets from the entire glass surface, which was mechanically impossible with conventional wipers, and to eliminate the negative impact on visibility caused by the wiper arm.

・Means to solve the problem ■ A powerful and quiet air pump ■ A strong air nozzle that discharges high-speed air that can replace conventional wiper blades ■ A motor that counter-rotates the air nozzle ■ Heats the high-speed air Weathered vine piping■ Water droplet remover for helicopters (does not need to be used in combination) High-velocity wind creates a strip of anhydrous droplets on the glass surface, and banks of water droplets are formed on both sides of the strip.

By counter-rotating the bank, water droplets in the direction of travel of the nozzle can be wiped away.

Example none.

Claims (1)

[Claims] [1] High-speed wind is blown from the nozzle [1] toward the glass [2] surface with an interior angle [3] of 90 degrees or less that is close to parallel to the glass surface, and the high-speed wind (jet stream) is blown onto the glass surface to avoid rainy weather. It moves in a counter-rotational motion while blowing away water droplets, and removes water droplets from all glass surfaces. These forms [2] Shape of the wiper nozzle [3] In order to uniformly apply high wind speed to the glass surface from the wiper nozzle [1], the discharge port [4] of the wiper nozzle is made oval. Its shape [4] High-speed wind is generated by the engine, and becomes warm air by preheating the engine. Their form [5] against the glass surface of the nozzle [1] according to the vehicle speed,
Change angle and distance. The interior angle [3] is large at high speeds and small at low speeds. These forms [6] Adjust the air volume and nozzle rotation amount according to the amount of rain; if the amount of rain increases, increase the speed and volume of high-speed wind, and change the wiping speed and angle. Their form [7] Form of the entire air wiper system
