Technical Field

The invention relates to an automobile windshield, in particular to an electric defrosting and demisting device for an automobile.

Background

At present, the most common automobile is defrosting and demisting through an air conditioning system, namely, air flow in an air conditioning evaporation box is guided to a front windshield through a defrosting and demisting port, so that defrosting and demisting are realized. The device for removing snow, frost and fog of an automobile, as disclosed in CN205854092U, comprises a rear windshield, a front windshield, a side window and a rearview mirror which are arranged in parallel, wherein the rear windshield, the front windshield, the side window and the rearview mirror are respectively connected with a heat conduction switch of the heat pipe device through a first heat pipe, a second heat pipe and a sixth heat pipe; and the heat conduction switch is connected with the engine shell through a seventh heat pipe. The heat of the automobile engine and the tail gas of the engine is fully utilized, and the good heat conductivity of the heat pipe is fully utilized. The water drops, snow, fog and frost can be removed at any time through the excellent heat conductivity of the heat pipe. And a switch is arranged, so that the switch can be turned off at any time. The safety of traveling is improved, and simple structure, convenient to use, the energy saving. However, the defrosting and demisting modes have the defects of slow defrosting and demisting, time waste, fuel oil waste and environmental pollution caused by waiting for defrosting and demisting; the frosting and fogging in the driving process can limit the visual field environment of a driver, the defrosting and demisting can shift the attention of the driver, and the safe driving cannot be guaranteed. Some automobiles achieve defrosting and demisting by installing an electric heating wire on the inner surface of a windshield. Because the arrangement of electric heating wire can influence the field of vision, generally arrange on the windshield of back, front windshield is generally not installed additional. When the automobile frosts and becomes fog, the front windshield glass is kept clean and bright by quickly defrosting and demisting, a safe visual field environment is provided for a driver, and the driving safety is ensured. Therefore, it is necessary to develop a device for quickly defrosting and demisting the front windshield of an automobile.

CN212022585U discloses an equipment body throttling device for improving defrosting and demisting performances of a front windshield of a passenger car, which is characterized in that through connection optimization between the equipment body throttling device and a passenger car instrument desk, when a defroster device is connected with an air outlet of the instrument desk, a round adjustable air outlet on the instrument desk is arranged corresponding to the position of the air outlet on the defroster body, and the equipment body throttling device is installed; the wind speed of the long air outlet is obviously improved when the regulation proportion is 50 percent; when the front windshield needs defrosting and demisting, the best effect can be achieved within standard time. The structure is simple, and only a throttling device of the equipment body is needed to be added at a position of a respective air outlet on the defroster device; the problem that the wind speed of the long air outlet of the instrument desk is low can be effectively solved. The technical solution disclosed in this patent document is a useful attempt in the field of the technology.
