Abstract

An apparatus for injecting air to a windshield of a vehicle is provided to prevent attachment of foreign substances and frost formation on the windshield by injecting the air in the upward direction of the windshield when the vehicle is moving. An apparatus for injecting air to a windshield of a vehicle is installed in a cowl on the lower side of the windshield. The apparatus includes air injection holes, an air supply pipe(40), and a blower(50). The air injection holes inject air to prevent attachment of foreign substances to the windshield of the vehicle. The air supply pipe is engaged with the air injection holes. The blower supplies air to the air supply pipe. An air injection section connected to the air injection holes is engaged with one side surface of the air supply pipe. An air supply section is formed on the other side surface of the air supply pipe. The outer diameter of the air supply section is enlarged to supply air and to increase the flow rate of the air.

The present invention relates to a windshield air injector of an automobile, and more particularly, by injecting air in an upward direction of the windshield during driving of the vehicle, it is possible to keep the windshield clean by preventing foreign matter from attaching and freezing. The present invention relates to a windshield air injector of a vehicle capable of securing a visual field of a car and preventing safety accidents.

In general, foreign matters such as blades, dirt, etc. are attached to the vehicle when driving, and in this case, after the washer fluid is sprayed, the wiper arm of the wiper device is rotated to wipe the foreign substances with the wiper blade.

However, if a large amount of foreign matter is attached to the windshield of the car, it will not be wiped smoothly even if it is sprayed by the washer liquid, and it will damage the wiper plate and the windshield by using the wiper for a long time. In addition, there is a problem that not only can not easily remove the foreign matter attached to the driving of the vehicle, but also obstructs or obstructs the driver's field of view, thereby including a risk of a safety accident.

The present invention has been made to solve the above problems, an object of the present invention is to spray the air in the upper direction of the windshield during driving of the vehicle to prevent the adhesion of foreign matters and to keep the windshield more clean, By attaching a small amount of foreign matter to the windshield, it is not only easy to remove by using a wiper but also to secure the driver's vision, thus providing a windshield air injector of a vehicle that can prevent safety accidents. .

The configuration of the present invention for achieving the above object, the air blowing hole for the air is ejected to prevent the adhesion of foreign matter to the windshield of the vehicle, the air supply pipe coupled to the air blowing hole, and supply air to the air supply pipe In the air injector is configured to a blower is installed in the lower cowl of the windshield, the air blowing holes are formed in the cowl at a predetermined interval, the air supply pipe is air connected to the air blowing hole on one side It is characterized in that the air supply unit is formed so that the outer diameter is expanded to increase the flow rate while the air is coupled and the air is supplied to the other side.

Hereinafter, with reference to the accompanying drawings will be described in detail the windshield air injector of the vehicle of the present invention.

1 is a schematic perspective view showing a windshield air injector of a vehicle according to the present invention, Figure 2 is a state diagram showing a state of use of the windshield air injector of a vehicle according to the present invention, Figure 3a is a schematic view of FIG. Phosphorus is a longitudinal cross-sectional view, and FIG. 3B is a schematic side cross-sectional view of FIG.

As shown in the figure, the windshield air injector of an automobile according to an embodiment of the present invention is a cowl provided on the lower side of the windshield 10 to prevent foreign matter from adhering to the windshield 10 of the automobile. A plurality of air blowing holes 30 are formed at a predetermined interval at a predetermined interval and the air is blown out so that foreign matters coming to the windshield 10 move upwards, and are connected to the air blowing holes 30 to the outside. Air supply pipe 40 for guiding the air supplied from the air to the air blowing hole 30, and an air compressor (not shown) or blower 50 for supplying air to the air supply pipe (40) It is configured by.

That is, after the air generated from the air compressor (not shown) or the blower 50 is moved through the air supply pipe 40, the air flows upwardly, ie, in the vertical direction, of the vehicle through the air ejection hole 30. By spraying not only prevents the adhesion of foreign matter to the windshield 10 of the vehicle, it is also possible to easily secure the driver's view by preventing freezing caused by snow in winter.

Here, a plurality of air ejecting portions 42 are respectively coupled to one side surface in the longitudinal direction of the air supply pipe 40 at regular intervals, and the other side surface receives the air and increases the flow velocity of the supplied air. The air supply unit 44 is formed to expand.

The air ejection unit 42 is formed in an elbow shape so as to eject air in the vertical direction through the air ejection hole 30, and one end is connected to the air ejection hole 30, and the other end is the air supply pipe 40. It is preferable to be coupled to the, it is preferable that the air ejected through the air blowing hole 30 is ejected in multiple directions so that the foreign matter is easily formed to enlarge the outer diameter to move to the upper side of the vehicle.

In this case, in the case of an air compressor (not shown) for supplying air to the air supply pipe 40, the high pressure air is configured to increase the pressure while compressing the outside air sucked into the engine when the vehicle is driven. Having an air compressor (not shown) to be configured to operate by using a separate switch.

On the other hand, the air supply pipe 40 is preferably fixed to the engine portion by using a bolt or nut on both sides and the bottom of the air supply unit 44 so as not to flow during the driving of the vehicle, it is supplied to the air supply pipe 40 The air supply pipe 40 is attached to the cowl 20 of the vehicle so that air is injected directly to the upper direction of the vehicle without passing through the air ejection unit 42 and the air ejection hole 30, and then the upper side is cut out to provide air. The air supplied to the supply pipe 40 may be injected upward.

Looking at the operation and effect of the present invention configured as described above, when operating the air compressor (not shown) or the blower 50 while driving of the vehicle, the air generated by the air compressor (not shown) or the blower 50 is After being supplied through the air supply unit 44, it is moved along the air supply pipe 40, and then sprayed upward through the air ejection hole 30 connected to the air ejection unit 42.

At this time, the air supplied to the air supply unit 44 is injected in a multi-direction through the air blowing hole 30 at a high blowing pressure by moving the air supply pipe 40 in a state in which the flow rate is increased, the front glass By raising the foreign matter coming to (10) to the upper side of the vehicle will be able to reduce the amount of foreign matter attached to the windshield (10).

Therefore, while keeping the driver's view while driving the vehicle, it is possible to easily remove a small amount of foreign matter attached to the windshield 10, thereby maintaining a clean state at all times.

According to the present invention as described above, by spraying the air toward the upper side of the windshield while driving of the vehicle to prevent the adhesion and freezing of foreign matter to keep the windshield more clean, a small amount of foreign matter is attached to the windshield wiper Not only can be easily removed by using it, but also the driver's vision can be secured, so there is an advantage of preventing safety accidents in advance.
