Definitions

  • the following description relates to a refrigerator having a storage compartment configured for a converted use as a freezing compartment or a refrigerating compartment.
  • a refrigerator is an apparatus configured for keeping food fresh by using a cold air flow generated from a cooling cycle.
  • a storage compartment of the refrigerator is divided into a refrigerating compartment configured to keep food refrigerated by maintaining the temperature at approximately 3° C, and a freezing compartment configured to keep food frozen by maintaining the temperature at approximately -20° C,
  • the amount of the food stored in the refrigerating compartment is generally more than the amount of the food stored in the freezing compartment, and therefore, the refrigerating compartment is configured to be provided with a larger size than the freezing compartment. Also, because the refrigerating compartment is more frequently accessed, the refrigerating compartment is provided at a lower portion of the refrigerator while the freezing compartment is provided at an upper portion of the refrigerator.
  • a cold air flow supply system of such refrigerator may be composed of in various methods. For example, a method to control the temperature of the freezing compartment at below 0° C and the temperature of the refrigerating compartment above 0° C by installing a damper apparatus at a cold air flow supply path for the refrigerating compartment and by adequately opening/closing the damper apparatus, while supplying the cold air flow generated from a single evaporating apparatus, is used.
  • a refrigerator having the freezing compartment converted to the refrigerating compartment or the freezing compartment turned off for a use may be considered, and an example of such a refrigerator has been suggested in Korean patent publication No. 10-2010-0076089 .
  • a refrigerator is provided with the damper apparatus configured to control the supply of the cold air flow to the freezing compartment and a means for heating the freezing compartment.
  • This refrigerator is configured to limit the cold air flow supply to the freezing compartment by the use of the damper apparatus in order to convert the freezing compartment to the refrigerating compartment, and at the same time, to heat up the freezing compartment.

  • the converting compartment 13 and the refrigerating compartment 14 are divided by a mid wall 16, and an insulator is foamed at an inside of the mid wall 16, thereby a heat exchange is prevented between the converting compartment 13 and the refrigerating compartment 14.
