Description

Anti-fog device of door glass

The present invention relates to a defogging device of the door glass, and in particular in the rainy weather and winter season, the frost caused on the door glass due to the temperature difference between the outside and the outside of the door glass is formed to be removed simply by lifting the door glass to lift and remove the visibility of the driver The present invention relates to a defogging device for door glass that can improve customer satisfaction and productability by satisfying various needs of customers as well as ensuring safe driving.

In general, a door (DOOR) used in automobiles has a structure in which a frame (door frame) surrounding a window glass is attached by combining an outer panel of the outside and an inner panel of the inside. The door is formed by integrally molding a door frame and an out panel, which is called a door or a full door.

The door is a door that is opened and closed first when the passenger boards the inside of the boarding room or when the boarding passenger gets off, and the passenger is protected in the boarding room safely and comfortably within the limited space and weight of the boarding room. A pair of front and rear doors are rotatably opened and closed in one direction so that the front and rear sides thereof are respectively rotated.

In addition, to secure the driver's field of view, approximately half of the top of the door is raised or lowered by a fixed or manual or powered (Power window) door glass is formed.

The door glass is configured to be opened and closed by selective lifting and lowering for the convenience of passengers such as ventilation in the car, temperature and humidity control, and the driver operates while operating the cooling / heating device during rainy weather or during winter driving. As a result, the temperature and humidity in the passenger compartment are increased. At this time, the fog is generated on the door glass due to the temperature difference between the inside and the outside of the cab, so that the driver's vision is disturbed. The driver frequently removes the fog on the door glass by wiping with a wet cloth.

On the other hand, the windshield glass in front of the cab is used by blowing the hot / cold air evenly through the defroster grill on the inner side of the instrument panel to remove steaming or frost. In the rear window glass at the rear, a plurality of electric resistance heating wires are inserted at predetermined intervals on the inner surface, and an electric heating type is installed to remove the steaming and melting of the glass to warm the window.

In addition, in order to secure the view of the side mirror, a front door is used in which a partial cold / hot air is blown so that only a side mirror can be seen to remove some mist in a predetermined range.

Therefore, the steaming generated in the door glass is a situation where the driver has to clean the inner surface of the glass by hand or lift and lower the door glass to roughly remove it by using the weather strip to secure the view.

However, such a conventional door glass is difficult to drive safely because the vision of the outside situation is blocked when the steaming occurs on the inner surface, when the driver directly or in the passenger seat in the passenger seat signal the left / right door glass together When it does not interfere with driving after waiting or stopping for a while, it is often wiped off with a wet hang-up etc. to temporarily remove the fog, thus reducing the concentration of driving and distracting the mental power, increasing the risk of traffic accidents and reducing the safety as well as various needs of customers. There is a drawback that the marketability of the product is deteriorated because it is not satisfied.

In addition, if it is difficult or cumbersome to remove the mist by the above method, the door glass is raised and lowered and removed by the weather strip, but due to the frequent use of the door glass, the function decreases and thermal deformation or processing and assembly is caused by the weather strip aging. Clearance is difficult due to gaps, so it is difficult to remove the rim completely, and the efficiency is reduced, and the reliability is lowered. Also, partial cold / hot air is blown so that only the side mirror can be seen. The door is limited in that the entire steaming can not be removed efficiently and the inconvenience of use and only the local range is removed.

Therefore, the present invention has been made to solve the fundamental problems of the prior art, the purpose is to remove the frost caused on the door glass by the temperature difference between the outside of the cabin and rainy weather during the rain and winter simply and easily lifted the door glass to remove It is formed to ensure that the driver's view to ensure safe driving is made, as well as to satisfy the various needs of customers to provide a defrosting device of the door glass that can improve the satisfaction and productability of the product.
