Description

In the present invention, when the windshield wiper wipes off the snow adhering to the windshield on the outside air side of the vehicle during snowfall in winter, a part of the snow that has fallen is compressed and the snow that has accumulated in the lower part of the windshield is heated with warm air. It relates to technology for melting.

There was no device that would allow safe and comfortable driving, except for the snow and ice that was overwhelmed during the snowfall.

In particular, in the case of a bonnet-type vehicle, the field of view is gradually narrowed by the snow that is compressed between the lower part of the outside windshield and the bonnet by the wiper blade.
In cold regions, there is a problem that prevents safe driving due to surface icing of the windshield.
The present invention has been made to solve this problem.

A small heat exchanger (radiator) is installed at the lower part of the windshield and at the rear of the bonnet. The engine cooling water (about 92 ° C) is passed through it, and hot air is generated by the blower fan. Along the surface, snow and ice are melted by spraying on and around the snow-capped spot. Moreover, the warm air generated by the indoor heater (heater) is guided to the lower part of the windshield on the outside air side and blown upward along the glass surface.
Also, use a viscous heater or electric heater as a heat source to generate warm air, blowing snow and ice around the area where the snow is pressed and its surroundings.

It secures the front view of the windshield and is useful for safe driving and safe operation.

A radiator (heat exchanger) and a blower fan are installed in the engine room under the windshield. Cooling water supplied for engine cooling is passed through this heat exchanger (radiator) to generate hot air, and through the ventilation pipe, The wind should be blown from a nozzle with a shape that spreads well around the snow-capped part. The tip of the nozzle has a shape that is difficult to block with snow.

The point where the snow was pressed and the visibility was poor was shown. The relationship between the heat exchanger for melting snow (radiator), the blower fan unit, and the hot air is shown.

Claims (3)

A mechanism device that melts hot snow or frozen ice by blowing warm air upward from the lower part of the windshield on the outside air side of vehicles (including passenger cars, commercial vehicles, trucks, working vehicles, etc.). Hot air (10-98 ° C.) is used to melt snow and ice. The heat source of the warm air is engine cooling water, indoor heater, heating wire, viscous heater, etc.
