Method for controlling refrigerator

Abstract

A method for controlling a refrigerator according to an embodiment of the present invention comprises: if an ultra-low temperature compartment mode is turned on, performing control such that one of low voltage, middle voltage, high voltage, and reverse voltage is applied to the thermoelectric module according to the operation mode of the refrigerator; and if the temperature of the ultra-low temperature compartment is determined to be in a satisfactory temperature range, applying low voltage to the thermoelectric module by the control unit.

Description

technical field [0001] The invention relates to a control method for a refrigerator. Background technique [0002] In general, a refrigerator is a household appliance that stores food at low temperatures, including a refrigerator for storing food in a refrigerated state within a range of 3°C, and a freezer compartment for storing food in a frozen state within a range of -20°C. room. [0003] However, if food such as meat or seafood is stored in a frozen state in the current freezer, the water in the cells of the meat or seafood flows out of the cells during the process of freezing the food at -20°C, causing the cells to destroyed, and a change in taste occurs during thawing. [0004] However, if the temperature condition of the storage compartment is set to an extremely low temperature state significantly lower than the current freezer compartment temperature, whereby the food quickly passes through the freezing point temperature range when changing to a frozen state, cell...

AI Technical Summary

Problems solved by technology

[0027] If the user uses a tool to remove the frost attached to the outer wall of the deep freeze chamber, it may cause damage to the outer wall of the deep freeze chamber

[0028] If you choose the method of thawing the frost by stopping the operation of the freezer, it may cause the following problems: if the food stored in the freezer is not moved elsewhere, the food will spoil

[0029] Although refrigerators with a structure in which the deep freeze compartment is accommodated inside the freezer compartment have serious problems as described above, in the prior art 2, neither these foreseeable problems nor the solution to the occurring problems are mentioned. solutions to the problem
