Abstract

PURPOSE:To ensure the visual field of a window in a constantly excellent state despite of a weather state by a method wherein compressed air generated through the working of a compressor is blown through a compressed air discharge port against the front of the window to blow off an adhered substance, e.g. raindrops, dust. CONSTITUTION:During the stop of a vehicle or normal running, air is sucked through an air suction port 14 and compressed through the working of a compressor 15 to produce compressed air, which is blown through a compressed air discharge port 11 against the surface of a window 92 by means of a duct 13. As a result, an adhered substance, e.g. raindrops, on the surface of the window 92 is blown off. In this case, coupled with formation of a water repellent silicon deposition film on the surface of the window 92, raindrops and the like are removed with high efficiency. During high speed running, the flow of the open air during running is guided by an air spoiler 12, and through the rise of the flow of the open air along the surface of the window 92, an adhered substance on the surface of the window 92 can be blown off.

Description

[Detailed description of the invention] [Industrial application field] The present invention improves visibility through the vehicle window.

The present invention relates to a window deposit removal device.

(Prior Art) As is well known, vehicle windows have traditionally been used to remove deposits such as raindrops, snowflakes, and debris.

Wipers are provided.

This wiper has a blade that contacts the front of the window and is driven by a small motor.

The blade portion is made of rubber or synthetic resin.

Additionally, two wipers are usually provided, each wiping the front of the window in a fan shape.

[Problem to be solved]

However, since the blade portion of the above-mentioned wiper is made of rubber or synthetic resin, it deteriorates and its function as a wiper deteriorates. Particularly in the summer, the blade may adhere to the windshield.

Further, the wiper reciprocates in the driver's front field of vision, which obstructs the driver's field of vision.

Particularly, when driving at night in rainy weather, not only is visibility insufficient, but the wiper also obstructs the visibility, making driving difficult. Furthermore, the wipers.

Because it uses reciprocating motion to remove deposits on the window, good visibility can only be obtained intermittently, and
The wipers are also visually unsightly.

In view of these conventional problems, the present invention completely eliminates the concept of conventional wipers, and can always ensure a full field of view of the window even in rainy weather. It is an object of the present invention to provide a device for removing deposits from windows.

[Means for solving problems]

The present invention has a compressed air outlet provided below the front of a vehicle window, an air spoiler provided in front of the compressed air outlet, and an air intake port provided in front of the air spoiler. A device for removing deposits from a vehicle window is characterized in that a blowing compressor is disposed inside the mouth.

In the present invention, the air spoiler efficiently guides airflow from the front to the window when the vehicle is running.

It is a kind of guide plate.

In addition, the air intake port is located on the bonnet in front of the window.
It is provided by cutting out a portion of the top surface of the bonnet. The compressor is a blower that sucks and compresses air from the air intake port and forcibly blows the obtained compressed air onto the window surface from the air outlet.

Further, in the above-mentioned deposit removing device, a wind speed sensor may be provided in front of the window, and the amount of air blown by the compressor may be controlled according to the wind speed that the window receives.

That is, when the vehicle speed is low or there is a tailwind, the amount of air blown by the compressor is increased, and when the vehicle speed is high or there is a headwind, the amount of air blown is decreased. The amount of compressed air blown is controlled by adjusting the rotation speed of the compressor.

This is done by adjusting the amount of compressed air blowing out.

Further, in the above-mentioned deposit removing device, it is preferable that the surface of the window is treated to make it highly water-repellent, thereby ensuring even better visibility. Examples of such surface treatments include evaporating silicon on the window surface and applying a surface treatment agent such as liquid resin (acrylic or the like) to the window.

[For production]

In the deposit removal device of the present invention, the compressor is operated and air is introduced from the air suction port to produce compressed air. Then, the compressed air is blown onto the front surface of the window through the compressed air outlet. This blows away raindrops, snowflakes, debris, and other deposits on the window, keeping the front surface of the window clean at all times.

Furthermore, when the vehicle speed is high, in addition to the compressed air from the compressor, an air spoiler efficiently directs outside air from the front of the vehicle onto the window surface. At high vehicle speeds, the outside air guided by the air spoiler is used primarily to remove deposits, and the amount of compressed air by the compressor is reduced. The amount of compressed air in this compressor is controlled by a wind speed signal from a wind speed sensor.

[Effects] As described above, in the present invention, deposits are removed using compressed air, so there are no obstructions to visibility in front of the window.Furthermore, with the conventional one-wiper type, the window can only be shaped into a fan shape. However, according to the present invention, the entire surface of the window can be kept clean at all times.

Therefore, according to the present invention, the entire field of view of the window can be ensured at all times even in rainy weather. A vehicle window deposit removal device can be provided.

Furthermore, according to the present invention, there is no deterioration like in conventional wipers.

Furthermore, the compressor can be controlled by the wind speed sensor to supply compressed air to the window according to the wind speed.

It is the roof of the vehicle.

Next, each effect will be explained.

First, when the vehicle is normally running or stopped, the compressor 15 is operated to suck and compress air from the air intake port I4, and the obtained compressed air A is sent to the duct 1.
3, the compressed air is blown out from the outlet 1) onto the surface of the window 92, thereby removing deposits such as raindrops on the surface of the window 92.

It is blown away by compressed air A. In addition, since a water-repellent silicon vapor deposited film is provided on the surface of the window 92, raindrops are efficiently removed by this water-repellent effect and the compressed air.

Next, during high-speed driving, the flow of outside air during driving is efficiently guided by the air spoiler.

The outside air rises along the surface of the window 92.

Therefore, the surface of the window 92 is efficiently blown away.

In addition, in this example, the wind speed associated with high speed is detected by the wind speed sensor 21, and when the wind speed increases (for example, 80 h/hour), the controller 20 reduces the rotation speed of the compressor 15 to half of the normal speed. and reduce the amount of compressed air supplied. Thereby, the power consumption of the compressor 15 can be reduced, and the flow of outside air caused by the air spoiler 12 is not disturbed. The amount of compressed air supplied by the controller 20 is adjusted not only by adjusting the rotational speed of the compressor I5 as described above but also by adjusting the compression set pressure.
