The present invention provides a drainage device for a wall washer to prevent a hand from reaching an inlet (220) even if the hand is placed in towards a side where a cap (300) was mounted after the cap (300) is removed, and to prevent an accident due to a high temperature of a heater, by comprising: an inlet (220) formed on one side with a valve wall (212) as a standard; a drainage hole (230) formed on the other side with the valve wall (212) as the standard; and a cap (300) mounted on the same side as that of the drainage hole (230), wherein the distance from the part where the cap (300) is mounted and the inlet (220) being folded in a zigzag shape becomes longer. |
