A built-in refrigerator includes a water and drinks dispenser, or an ice maker, placed on the outside of the refrigerator door. The refrigerator is installed in a modular kitchen furniture unit provided with a door panel. A sliding connection between the dispenser and the door panel of the furniture unit allows the simultaneous opening and closing of the door and the door panel and, when the door is in the closed position, prevents residual liquids or solids from falling into the air space existing between the door and the door panel.
