WINDOW FRAME HAVING DRAINING WATER STRUCTURE

摘要

PURPOSE: A window frame having a drainage structure is provided to enhance water-tightness and air-tightness and to enable inner humidity to be appropriately maintained by the preventing of defect and contamination due to inner dew. CONSTITUTION: A window frame having a drainage structure comprises a plurality of horizontal and vertical frames(1) and a drainage unit(10). The frames are connected in a shape of polygonal frame and supports window glass. The drainage unit is placed on a horizontal frame and is located at the boundary between the horizontal frame and the inner corresponding surface of the window glass. A trap is formed in the drainage unit and the moving flow of the dew is extended and then is externally discharged.
