Abstract

A method for controlling a refrigerator according to an embodiment of the present invention is characterized by comprising: a step for determining whether a defrosting period (POD) for defrosting a freezing chamber and a deep freezing chamber has elapsed; a step for, when it is determined that the defrosting period has elapsed, performing a deep cooling operation for bringing at least one among the temperature of the deep freezing chamber and the temperature of the freezing chamber down to a temperature lower than a control temperature; and a step for defrosting the deep freezing chamber when the deep cooling operation is terminated, wherein, when the defrosting of the deep freezing chamber is started, a freezing chamber valve is closed to block cold air flow to a heat sink, the defrosting of the deep freezing chamber includes cold sink defrosting and heat sink defrosting performed after the cold sink defrosting is completed, and while the heat sink defrosting is being performed, a deep freezing chamber fan is driven to remove water vapor generated during the cold sink defrosting.

Description

technical field

[0001] The invention relates to a control method for a refrigerator. Background technique

[0002] Generally speaking, a refrigerator is a household appliance for storing food at low temperatures, which includes a refrigerator for storing food in a refrigerated state in the range of 3°C and a refrigerator for storing food in a frozen state in the range of -20°C. Freezer.

[0003] However, in the case of storing food such as meat or seafood in a frozen state in the current freezer, during the process of freezing the food at -20°C, water in the cells of the meat or seafood will flow out of the cells Escape, destroy cells, and change the food texture during the thawing process.

[0004] However, cell damage can be minimized if the temperature condition of the storage room is created to be in an extremely low temperature state that is significantly lower than the current freezer temperature, so that when the food changes to the frozen state, it quickly passes t...
