Abstract

In addition to the DEF, FACE, and FOOT outlets of conventional air conditioners for automobiles, an outlet is provided outside the windshield. Warm air is blown out from the outside of the windshield to eliminate the temperature difference between the inside and outside of the windshield and eliminate frost and frost. While the wiper is in operation, warm air is blown out from the air outlet on the outside of the windshield to evaporate the remaining moisture and melt the snow below the windshield. Also, the raindrops are blown away by blowing air from the outside of the windshield.
[Effect] To eliminate cloudiness and frost adhering to the windshield, the air volume at the outlet of the DEF can be reduced, the wind does not hit the face, etc. . In addition, after wiping the rain with a wiper, the windshield is improved in view of the windshield because it is dried and blown off with warm air coming out from the air outlet provided on the outside of the windshield with the remaining moisture and raindrops. In addition, the snow under the windshield can be melted.

Description

The present invention is for removing the fog and frost on the windshield, for drying the windshield after wiping rain with a wiper to increase visibility, for melting the snow under the windshield scraped off by the wiper, The present invention relates to a car air conditioner for blowing glass raindrops.

A conventional air conditioner has an air outlet (DEF) that blows to the inside of the windshield, an air outlet (FACE) that blows directly to the face, and an air outlet (FOOT) that blows to the feet.

In the conventional car air conditioner, since the fog adhering to the windshield is erased from the inside of the windshield by the cold air of the DEF outlet, the cold air hits the face and the like, which gives an uncomfortable feeling.

In the conventional car air conditioner, the frost attached to the windshield is erased from the inside of the windshield with the warm air of the DEF outlet, and the cold air cooled by the windshield hits the face and gives an uncomfortable feeling.

When the temperature of the outside air is relatively low, such as during the rainy season, there is a means for lowering the temperature inside the vehicle below the temperature of the outside air in order to prevent the occurrence of cloudiness, but because the temperature inside the vehicle is low, it feels cold.

In the conventional car air conditioner, the windshield keeps getting cold from the DEF outlet in order to remove the cloudiness inside the windshield, and the windshield is too cold, so that the fog may be generated outside the windshield.

Since conventional car air conditioners do not have an air outlet outside the windshield, there is no means for evaporating moisture on the windshield, and after wiping rain with a wiper, the moisture remaining on the windshield deteriorates the visibility of the windshield.

Since conventional car air conditioners do not have an air outlet on the outside of the windshield, there is no means for melting the snow below the windshield, and the snow scraped off by the wiper remains in the lower windshield.

Since conventional car air conditioners do not have an air outlet on the outside of the windshield, there is no means for blowing out raindrops on the windshield, and the use of the wiper causes the left and right movement of the wiper to obstruct the driver's front view.

In addition to the DEF, FACE, and FOOT air outlets of conventional air conditioners for automobiles, an air outlet is provided outside the windshield.

When the humidity inside the vehicle is high and the temperature outside the vehicle is lower than the inside of the vehicle, warm air is emitted from the air outlet outside the windshield, eliminating the temperature difference between the inside and outside of the windshield and eliminating the cloudiness.

When the temperature on the outside of the windshield is low and frost is likely to be formed, warm air is discharged from the air outlet on the outside of the windshield to eliminate the frost.

While the wiper is in operation, warm air is blown out from the air outlet outside the windshield to evaporate any remaining moisture.

In order to enhance the effect of eliminating the cloudiness, a waterproof heater that warms the windshield is added to the air outlet provided outside the windshield.

A motor-type blower that increases the wind speed is provided at the air outlet outside the windshield, and the raindrops are blown away with warm air.

In order to eliminate the occurrence of clouding on the outside of the windshield, clouding of the windshield is detected by a light sensor inside the windshield.

In order to eliminate the cloudiness and frost adhering to the windshield, the air volume at the DEF outlet can be reduced, and the wind does not hit the face and is comfortable.

Because the temperature inside the car does not decrease to eliminate the cloudiness and frost on the windshield, it is comfortable without feeling cold.

In order to turn off the fog on the inside of the windshield, warm air is blown out from the outlet on the outside of the windshield, and the temperature difference between the inside and outside of the windshield is eliminated. it can.

After the rain is wiped off with a wiper, it is dried with warm air coming out of the air outlet provided on the outside of the windshield with the moisture remaining after wiping, so visibility is improved.

Even if the snow scraped off by the wiper remains in the lower part of the windshield, it can be melted by the warm air coming out from the air outlet provided outside the windshield.

Since the rain is blown away by the warm air at the air outlet outside the windshield, the frequency of operation of the wiper can be reduced during rainfall.

The best mode for practicing the idea

Air outlets are added to the outside of the windshield in the DEF, FACE, and FOOT outlets attached to conventional car air conditioners. Moreover, a blower outlet switching damper is provided, and air blowing is switched by a blower outlet switching servo motor.

Cloudy and frost on the windshield are detected by the temperature sensor and the windshield light sensor, and the warm air from the air outlet provided on the outside of the windshield is applied to the front to eliminate the cloud and frost.

When the wiper is operated intermittently with the wiper operation switch, warm air from the internal heater is further applied to the front of the windshield, and the windshield wipes off the windshield. Evaporate the water.

During the operation of the wiper, the warm air from the internal heater is accelerated by the blower at the blowout port outside the windshield, hits the front, blows raindrops, and reduces the frequency of operation of the wiper.
