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 a vehicle suitable for securing a view of a side mirror and a side window of a vehicle, and removes water droplets and snow attached to the side mirror and the side window. The present invention relates to an air wiper for a vehicle that can be used as an antifogging device.

[0002]

2. Description of the Related Art Conventionally, as this kind of air wiper,
For example, an air wiper described in Japanese Patent Application Laid-Open No. 7-52755, a side mirror having a function of removing water droplets for vehicles described in Japanese Patent Application Laid-Open No. 11-157419, and the like have been proposed. The former air wiper has a built-in air compressor inside the hood, and the blast nozzle connected to this air compressor is installed facing the outer surface of the windshield, side mirror, side window, and rear window. The compressed air obtained by the compressor is blown onto each glass surface. Further, the latter side mirror having a function of removing water droplets for a vehicle has a configuration in which compressed air is generated by a compressor and a compression cylinder mounted in the vehicle body, and the compressed air is blown onto the surface of the side mirror.

[0003] Each of these conventional air wipers and side mirrors is a device for forcibly removing water droplets adhering to the side mirror and the side window with compressed air using a compressor, a compression cylinder or the like. Therefore, with these conventional air wipers and side mirrors,
The installation of these compressors and cylinders is a necessary condition.

[0004]

However, since a compressor, a compression cylinder and the like are used as described above, the problems of safety and storage are left. For example, mounting a compression cylinder in an engine room where the room temperature is high requires extremely high safety. Moreover, a compressor or a cylinder that supplies compressed air of a usable volume during traveling requires a large amount of storage space, so that even when stored in a place other than the engine room, there is a disadvantage that other spaces are sacrificed. .

After the compressed air is forcibly blown to the side mirrors and the side windows using a compressor or a compression cylinder to remove water droplets, the side mirrors and the side windows are blown by the compressed air blowing operation. In some cases, the temperature of the glass surface becomes extremely low and the glass surface becomes cloudy. Therefore, even if water droplets can be removed, it may be difficult to secure sufficient visibility.

Similarly, even if the snow on the glass surface of the side mirror or the side window is forcibly removed with compressed air, it is difficult to remove the snow if the snow is frozen on the glass surface. It is. In addition, since the temperature of the glass surface is further reduced, the icing state of the glass surface may be further deteriorated in some cases.

Therefore, the present invention has been made to solve the above-mentioned problems, and it is possible to continuously use the apparatus with a simple configuration having high safety, and to secure a view even in any situation. It is intended to provide an air wiper for a vehicle.

[0008]

Means for Solving the Problems To achieve the above object, a first means of the present invention is to provide a blower 1 for inducing and blowing warm air generated in an engine room R. The purpose is to spray water on the glass surfaces of the side mirror M and the side window W to remove water droplets and evaporate remaining moisture.

The second means blows warm air blown by the blower 1 onto the glass surfaces of the side mirror M and the side window W to prevent fogging.

A third means is to solve the problem by blowing warm air blown by a blower onto glass surfaces of the side mirror M and the side window W to dissolve and remove snow attached to the surfaces. And

According to the present invention, the warm air generated in the engine room is constantly blown on the glass surfaces of the side mirrors and the side windows, thereby removing the water on the glass surfaces and evaporating them. Is dissolved and removed.

[0012]

Embodiments of the present invention will be described below in detail with reference to the drawings.

Reference numeral 1 shown in the figure denotes a blower 1 for inducing and blowing warm air generated in an engine room R (see FIG. 1). The blower 1 includes a fan 1A and a motor 1B disposed in an engine room R, and is connected to a pipe 2 for inducing and blowing warm air. The blower 1 constantly or intermittently blows warm air generated in the engine room R onto the glass surfaces of the side mirror M and the side window W.

The blower 1 in the illustrated example is disposed in the engine room R, but is disposed near the glass surface of the side mirror M and the side window W, and heats up the engine room R through the pipe 2. Can also be induced. Then, a nozzle 3 is provided at the end of the pipe 2, and the nozzle 3 is directed to the glass surface of the side mirror M and the side window W. At this time, the angle of the nozzle 3 with respect to the glass surface is set in advance to an optimum angle. Further, the angle of the nozzle 3 may be freely adjusted. At this time, by enlarging the tip of the nozzle 3, warm air can be efficiently blown (see FIG. 2).

When the blower 1 blows warm air generated in the engine room R, the temperature of the warm air can be adjusted by mixing and adjusting the warm air with the outside air. Therefore, it can be used at an optimum temperature according to each case, such as when removing water droplets, evaporating remaining moisture, or when preventing fogging or dissolving and removing snow cover.

[0016]

As described above, the present invention achieves the original object.

That is, a blower 1 for inducing and blowing warm air generated in the engine room R is provided, and the warm air blown by the blower 1 is blown onto the glass surfaces of the side mirror M and the side window W to remove water droplets. By evaporating the remaining water, safety is high and continuous use is possible with a simple structure. As a result, the inconvenience that the operation for proper control of the compressor, the compression cylinder and the like, such as the conventional air wiper using the compressor and the compression cylinder, complicates the driving operation has been solved.

Further, since the warm air blown by the blower 1 is blown against the glass surface of the side mirror M and the side window W to prevent fogging, like a conventional air wiper, the side mirror M and the side window W There is no danger that the temperature of the glass surface drops extremely, and a sufficient field of view can be secured.

Moreover, the warm air blown by the blower is blown onto the glass surfaces of the side mirror M and the side window W to dissolve and remove the snow attached to the surfaces. Can be dissolved and removed without fail. Therefore, the risk that the frozen state of the glass surface of the conventional air wiper that forcibly blows the compressed air is further reduced is also eliminated.

As described above, according to the present invention, continuous use is possible with a simple configuration having high safety.
Various effects such as securing a view in all situations can be achieved.
