Abstract: PURPOSE: A water receptacle unit structure for refrigerator dispenser is provided to achieve an improved user convenience by allowing the water receptacle cover to be easily detached from the bottom surface of the dispenser. CONSTITUTION: A water receptacle unit structure comprises an accommodation portion(20) formed into a recess at a bottom surface(12) of a dispenser arranged at the refrigerator door; a water receptacle cover(14) to be coupled to the accommodation portion; and a protrusion(22) partially protruded from the inner periphery of the accommodation portion so as to support the water receptacle cover. When a user intends to detach the water receptacle cover, the user presses the end portion of the water receptacle cover where the protrusion is not formed. Then, the other end of the water receptacle cover is lifted, thus allowing the user to easily grasp the lifted end. As a consequence, the water receptacle cover is easily detached from the accommodation portion by raising the lifted end.
