PURPOSE: A window frame drain device with excellent airtightness is provided to enhance drainability by draining cleaning water smoothly and to improve airtightness by easily blocking outside air from flowing into a drainage hole. CONSTITUTION: A window frame drain device with excellent airtightness comprises a fixed body(10), an air inflow blocking plate(20), and space maintaining members. The fixed body is composed of a plate member(110) including a drain outlet(111) and a fixing member(120) inserted into the drain outlet of a window frame. The air inflow blocking plate includes a flexible connection(210) which is connected to the fixed body and blocks the inflow of outside air into the inside the drain outlet of the fixed body. The space maintaining members are formed in both front sides of the fixed body, maintain a space between the air inflow blocking plate and the fixed body, and prevent the lower part of the air inflow blocking plate from being rotated to the upper side of the fixed body. |
