Abstract

<P>PROBLEM TO BE SOLVED: To provide a jet type air wiper for removing rain or the like by jetting compressed air or water on a window from a spiral nozzle and expanding it on a glass in order to solve problems that a conventional wiper of a car performs a reciprocating motion in front of driver's eyes to obstruct the view or to form a poor view while driving a car in a rainy condition, and a rubber of the wiper has been consumable. <P>SOLUTION: Spirally shaped air and water 4 is jetted on a windshield glass 1, and rain is scattered in a diffusing manner, and emitted outside a car by a collecting frame 5. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

Technology field

  In order to solve the problems that conventional car wipers are obstructive when driving in the rain, poor visibility, and consumables, the present invention fires compressed air or water from a spiral nozzle to a window. A spray-type wiper that spreads on glass and removes rainwater.

  Conventionally, it is a direct wiping type, but in the case of wiping type with air and water from a long distance, its power is weak when it reaches the window.

Problems to be solved by the invention

Means for solving the problem

Air or water sprayed from a distance is blocked by air resistance, etc. and diffused to reach the window, and its force is weak. Therefore, air pressure is insufficient to remove rainwater. Therefore, compressed air or water is generated in a spiral motion when the compressed air or water passes through the nozzle, and the mass of air or water twisted up to the window is shot with the same principle as men's urine while maintaining momentum. The aim was to remove rainwater and the like on the surface of the window glass by impact.
Therefore, in order to remove rainwater etc. from the window glass, (1) change in nozzle angle at high speed, (2) rainfall, rainfall and angular change at low speed, and (3) rainwater mixed with mud in the front car during low rain driving. 4) Measures against cold weather such as snow and frost 5) Treatment of rainwater emanating from the window glass 6) Because of problems such as the distance between the nozzle tip and the window glass, it was compressed as a method of removing rainwater from the window glass It provides the principle of a jet-type air wiper that shoots while keeping momentum until air and water reach the window glass while spiraling.

The invention's effect

  In the present invention, there is no obstruction of the direct wiping type reciprocating motion and no wiping phenomenon in the intermittent state, and rainwater is always blown away, so that it is safe and clear.

  It is the schematic of the attachment part of this invention.   It is the theoretical detailed drawing of this invention.

Explanation of symbols

(1) is a window glass (2) is a compressed air generator (3) is a nozzle with a spiral shape (4) is air and water kept in a spiral motion (5) is a scattered rainwater recovery frame

Claims (1)

Compressed air or water is sprayed on the window from a spiral nozzle and collides with the window and spreads on the glass surface to remove rainwater etc.
