This dispenser model with door-in-door system and water purifier has a refrigerator on top and a freezer at the bottom. A part of the display overlaps the door to secure a space for water and ice dispensing and to give visual openness. With a sub-display applied, frequently used dispenser menus can be found easily. Also, metal is applied to the sliding table for convenience in dispensing a large quantity of water. Applied with a water purification unit comprised of a triple filter and a stainless steel tank, this “water purifier + refrigerator” is an innovative model designed to save electricity and provide a space for a water purifier.
