CONTROL METHOD FOR REFRIGERATOR

Document Type and Number:

WIPO Patent Application WO/2017/164711

Kind Code:

A1

Abstract:

The present invention relates to a control method for a refrigerator. The control method for a refrigerator according to the present invention comprises the steps of: driving a first cooling fan to cool a first storage chamber; adjusting a damper to cause cold air to simultaneously flow through first and second cold-air passages; adjusting a damper to reduce the opening angle of the first cold-air passage, when the temperature of a high-temperature chamber reaches a value smaller than or equal to a second reference temperature for the high-temperature chamber; adjusting a damper to reduce the opening angle of the second cold-air passage, when the temperature of a low-temperature chamber reaches a value smaller than or equal to a second reference temperature for the low-temperature chamber; and driving a second cooling fan to cool a second storage chamber, wherein, after the temperature of the high-temperature chamber reaches the value smaller than or equal to the second reference temperature for the high-temperature chamber, when a predetermined time passes or the sensed temperature of the high-temperature chamber reaches a first set temperature between a first reference temperature and the second reference temperature for the high-temperature chamber, the damper is adjusted to increase the opening angle of the first cold-air passage.
