Method for controlling refrigerator

Abstract

A method for controlling a refrigerator, according to an embodiment of the present invention, comprises: a step in which it is determined whether a period of defrosting (POD) for defrosting a freezing compartment and a deep-freezing compartment has elapsed; a step in which, when it is determined that the period of defrosting has elapsed, a deep cooling operation for cooling at least one from among the temperature of the deep-freezing compartment and the temperature of the freezing compartment to be lower than a control temperature is performed; and a step in which, when the deep cooling operation finishes, a defrosting operation for defrosting the freezing compartment and the deep-freezing compartment is performed. When the defrosting operation starts, a freezing compartment valve is closed so as to prevent cold air from flowing to a freezing compartment evaporator and a heat sink, and at least a portion of a freezing compartment defrosting section and at least a portion of a deep-freezing compartment defrosting section overlap with each other.

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...

AI Technical Summary

Problems solved by technology

Therefore, in the structure in which the hot-side radiator and the freezer evaporator are connected in series, there is a problem that the defrosting operation control logic adopted in the prior art 2 cannot be directly applied.

[0024] And, in the prior art 2, there is no specific method for how to solve the problem caused by the water vapor generated in the defrosting process of the deep freeze chamber and the freezer chamber
