  • Apparatus and method for removing moisture
    Patent number: 7231727
    Abstract: The present invention relates to a moisture removal apparatus and method for accurately detecting moisture generation in an early stage and quickly removing it so as to prevent steam or frost from being formed on glass surfaces of vehicles and industrial devices, and other surfaces. The apparatus comprises a surface resistance detector (50) including two detection terminals attached on an insulation surface with a predetermined gap therebetween, and showing different resistances according to an amount of moisture on the insulation surface; a static electricity preventer (60) preventing static electricity generation to the signal sensed by the surface resistance detector (50); a moisture sensor (70) determining moisture states through variations of the current that flows according to resistances of the surface resistance detector (50), and outputting a corresponding signal; and a driver (80) being operable to the signal output by the moisture sensor (70) and removing moisture generated on the surface.
