Abstract

The invention discloses an automobile headlamp demisting device and an automobile headlamp demisting method. The automobile headlamp demisting device comprises an air humidity sensor, an air conditioning controller, an air conditioning evaporator, an air inlet pipe, an air outlet pipe, an air inlet pipe control valve and an air outlet pipe control valve, wherein the air humidity sensor is arranged inside a headlamp; the air inlet pipe is connected with the air outlet side of the air conditioning evaporator; the air outlet pipe is connected with the air inlet side of the air conditioning evaporator; the air inlet pipe control valve and the air outlet pipe control valve are arranged on the air inlet pipe and the air outlet pipe respectively; and the air conditioning evaporator, the air inlet pipe control valve, the air outlet pipe control valve and the air humidity sensor are connected with the air conditioning controller. The automobile headlamp demisting method comprises the followingsteps of: detecting the humidity level in the automobile headlamp; treating by using the air conditioning controller; demisting in the headlamp; detecting the humidity level in the headlamp again; and demisting in the headlamp again. In the invention, the process requirements of sealing property of the automobile headlamp can be reduced, the manufacturing process can be simplified, and the demisting speed is high and the demisting efficiency is high.

Description

technical field [0001] The invention relates to an automobile headlight defogging device and method. Background technique [0002] Fogging of car headlights is a very common problem. Car headlights cannot be completely sealed due to manufacturing process problems. In the case of high air humidity, humid air can easily enter the interior of the headlights and cause fogging inside the headlights. When the surface temperature of the headlights is low or when the car is parked, the headlights are also prone to fogging. Fogging inside the car headlights will not only affect the appearance of the headlights, but most importantly affect the lighting effect of the headlights and the driver's driving vision, affecting the safety of driving. The current way to deal with the fogging of automobile headlights is usually to install a separate device inside the headlights to heat the inside of the headlights to defog, but because it is difficult to discharge the moisture inside the headl...
