Definitions

  • the present invention relates to a refrigerator and a method for manufacturing said refrigerator.
  • a refrigerator is a device for low temperature storage of food and may be configured to provide freezing storage or cold storage of food according to the kind of food a user wants to store.
  • the inside of a refrigerator is cooled by a supply of cold air; this cold air is continuously generated by a heat exchange process with a refrigerant, based on a freezing cycle which goes through a process of compression-condensation-expansion-evaporation.
  • the cold air supplied to the inside of the refrigerator is evenly transferred to the inside of the refrigerator by convection.
  • the main body of a refrigerator has a rectangular parallelepiped shape, the front surface of which opens, and the main body of the refrigerator may harbor a refrigerating compartment and a freezing compartment. Further, the front surface of the main body may be provided with a refrigerating compartment door and a freezing compartment door for selectively shielding an opening portion.
  • a storage space in the refrigerator may be provided with multiple drawers, shelves or receiving boxes in which various foods may be stored in an optimal condition.
  • Top mount type refrigerators in which a freezing compartment is positioned in the upper section and a refrigerating compartment is positioned in the lower section, are well-known. Recently, however, for user convenience, bottom freezer type refrigerators (in which the freezing compartment is positioned in the lower section) have been produced. In the case of the bottom freeze type refrigerator, the more frequently used refrigerating compartment is positioned in the upper section and a relatively less used freezing compartment is positioned at a lower position; thus, a user may conveniently use the refrigerating compartment. However, since the freezing compartment is located in the lower section, the bottom freezer type refrigerator has a disadvantage in that a user needs to bend down to open the freezing compartment door to take out ice.
  • a refrigerator has been produced in which a dispenser for taking out ice is installed in the refrigerating compartment door positioned in the upper part of the bottom freeze type refrigerator.
  • the refrigerating compartment door, or the inside of the refrigerating compartment may be provided with an ice machine which generates ice.

Therefore, portions of an insulator 22a for the ice machine 20 that are disposed in the parts of the ice machine 20 that make contact with the inner layer of the housing of the refrigerator 2 overlap with the insulator 24 for the housing of the refrigerator 2.
  • the overlapping insulation structure increases the number of parts, thereby increasing the material cost.
  • the casing of the ice machine is assembled by coupling parts to each other, but there is a problem in that the junction of the coupled parts of the casing is not always reliably sealed.
  • a refrigerator configured so that the internal capacity thereof can be increased by reducing a dead space in the refrigerator.
