  • the refrigerator according to the embodiments may include one storage chamber 20 having the drawer-type door 25, or a plurality of the storage chambers.
  • the machine chamber receives parts including a compressor (not shown) compressing refrigerant, and a condenser (not shown) condensing the refrigerant supplied from the compressor.
  • the machine chamber is partitioned from the storage chamber 20.
  • a foam 15 such as foamed urethane is stuffed in a space between the outer case 11 and the inner case 13 for heat insulation.
  • An evaporator 50 in which refrigerant flows to maintain a low inner temperature of the storage chamber 20, is mounted in the space filled with the foam material 15.
  • the evaporator 50 takes the form of a general refrigerant pipe.
  • the evaporator 50 is mounted to surround both lateral sides and a bottom side of the drawer-type storage chambers 20b and 20c. That is, the evaporator 50 having the refrigerant pipe form is mounted in contact with an inner wall of the inner case 13 so as to surround both sides and the bottom side of the storage chambers 20b and 20c.
  • Cold air transferred from the evaporator 50 to both sides and the bottom side of the storage chambers 20b and 20c is supplied through natural convection of inner air of the storage chambers 20b and 20c.
  • the air cooled by heat exchange at the evaporator 50 moves down while warm air moves up.
  • the temperature of the storage chambers 20b and 20c is decreased through such air convection.
  • a heater (not shown) using electric heating wires may be mounted between the outer case 11 and the inner case 13 to heat the inside of the storage chamber 20, so as to mature the stored kimchi by maintaining a predetermined temperature proper for maturing thereof.

  • Flanges 31 are integrally extended outward from both upper ends of the basket 30 so as to be removably mounted to the mounting member 60.
  • a bending prevention member 80 is mounted at a bottom side of the basket 30 so that the basket 30, which is made of plastic, is not bent due to repeated thermal expansion and contraction.
  • the bending prevention member 80 may be mounted in a lateral direction at the bottom side of the basket 30.
  • Moving rails 61 are mounted at both sides of the mounting member 60 in a longitudinal direction so that the doors 25b and 25c are moved in a drawer system, thereby opening and closing the storage chambers 20b and 20c.
  • fixed rails 63 are formed on both sides of the inner case 13 for slidable engagement with the moving rails 61 of the mounting member 60. Specifically, the fixed rails 63 are mounted in a longitudinal direction on the inner wall of the inner case 13.
  • the basket 30 mounted to the mounting member 60 may be moved forward and backward according to the sliding movement of the moving rails 61 engaged with the fixed rails 63. Accordingly, the user is able to put in and take out food stored in the containers 40 with respect to the basket 30.
  • a temperature deviation occurs between an upper part and a lower part of the storage chamber 20 by the natural convection by the evaporator 50 during the operation of the refrigerator. Especially, the temperature deviation is greater between upper and lower front parts of the storage chambers 20b and 20c, the front parts adjacent to the doors 25b and 25c.
  • an auxiliary cooling member 70 is provided to reduce the deviation of the inner temperature of the basket 30.
  • the auxiliary cooling member 70 may be formed of a high thermal-conductivity material including metal such as iron and aluminum, alloys, resins and the like. According to an exemplary embodiment, an aluminum plate may be used as the auxiliary cooling member 70.
  • the auxiliary cooling member 70 made of the high thermal-conductivity material is disposed adjacent to the evaporator 50 contacting both sides and the bottom side of each of the storage chambers 20b and 20c. Here, the auxiliary cooling member 70 is brought into surface-contact with both outer sides and the bottom side of the basket 30 at the front area of the basket 30.
  • high temperature at the upper front part in the basket 30 is transferred to the lower front part in the basket 30.
  • the high temperature of the upper front part inside the basket 30 is transferred to the auxiliary cooling member 70 having a low temperature and being disposed adjacent to the evaporator 50, through an upper end of the auxiliary cooling member 70. Accordingly, the temperature deviation between the upper and the lower front parts of the basket 30 may be reduced.
  • both sides and the bottom side of the basket 30 may be frozen by the cold air from the evaporator 50 since these elements are adjacent to the evaporator 50.
  • freezing may be prevented by the high temperature of the upper front part of the basket 30 transferred through the auxiliary cooling member 70.
  • a refrigerator according to the embodiments may reduce the temperature deviation between upper and lower front parts of a storage chamber, by using an auxiliary cooling member.
