Definitions

  • the present invention relates to a refrigerator. More particularly, to a refrigerator including a door assembly having a ventilating hole.
  • a conventional refrigerator includes a main body cabinet having storage compartment, a door provided to the main body cabinet to open and close the storage compartment, and a cooling system supplying cool air to the storage compartment.
  • the cooling system is a direct cooling type system in which an evaporator is provided to an outer surface of an inner cabinet and directly exchanges heat with the storage compartment, and an indirect cooling type system in which cool air around an evaporator is supplied to the storage compartment by a fan.
  • a conventional refrigerator 100 includes a plurality of main body cabinets 101 respectively provided with a storage compartment 103.
  • a door assembly 110 is slidably coupled to each main body cabinet 101 to open and close the storage compartment 103.
  • the door assembly 110 is provided with a supporting frame 112 supporting a storage container 111.
  • the door assembly 110 includes a door cover 113 integrally coupled to the supporting frame 112 and provided with a handle 114.
  • a couple of guide rails 102 for the opening and closing of the door assembly 110 are disposed in opposite sides of the storage compartment 103 of the main body cabinet 101.
  • a slide rail 120 is slidably coupled to each guide rail 102, and is slidably coupled to the supporting frame 112 of the door assembly 110.
  • the slide rail 120 allows the door assembly 110 to smoothly slide with respect to the main body cabinet 101.
  • the supporting frame 112 and the slide rail 120 contact with external air, and consequently, moisture in the external air may be frozen. Since the supporting frame 112 and the slide rail 120 are cooled by cool air of the storage compartment 101, when the door assembly 110 is drawn to the outside, the supporting frame 112 and the slide rail 120 are exposed to external air having relatively high temperature. At this time, moisture in the external air contacts with the supporting frame 112 and the slide rail 120 and becomes saturated to be condensed or frozen. Also, when the door assembly 110 remains inside the storage compartment 103, the condensed or frozen moisture becomes hard by cool air of the storage compartment 103. As the opening and closing of the door assembly 110 is repeated, the frozen moisture is accumulated.
