DEFFOGING SYSTEM OF CONSTRUCTION MACHINERY

摘要

PURPOSE: A defogging system for construction equipment is provided to increase stability and work efficiency by always securing a clear view while a user operates the construction equipment. CONSTITUTION: A defogging system for construction equipment comprises an auto-defogging sensor(130), an internal temperature sensor(150), and a control part(170). The auto-defogging sensor is installed on a windshield of a cab of the construction equipment to detect the surface temperature of the windshield and the internal humidity of the cab. The internal temperature sensor is installed inside the cab to detect the internal temperature of the cab. The control part is connected to the auto-defogging sensor and the internal temperature sensor. When the difference between the surface temperature and a dew point is less than a threshold value, the control part operates an air conditioner(190) to defog the windshield.
