Title:
DEFROSTING CONTROL METHOD FOR REFRIGERATOR AND REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2019/052512
Kind Code:
A1
Abstract:
Disclosed are a defrosting control method for a refrigerator (100) and the refrigerator (100). The defrosting control method for a refrigerator (100) comprises: acquiring a defrosting start signal from the refrigerator (100) (S302); according to the defrosting start signal, enabling a compressor (30), a fan (23), a heating device (40) and a branching air supply device (20) to operate according to an operating state corresponding to the defrosting start signal (S304); acquiring a defrosting end signal from the refrigerator (100), and a temperature at the branching air supply device (20) (S306); and when the temperature at the branching air supply device (20) is less than a first pre-set temperature, enabling the branching air supply device (20) to continuously operate, and when the temperature at the branching air supply device (20) is less than a second pre-set temperature, enabling the branching air supply device (20) to stop continuously operating (S308). By means of the temperature at the branching air supply device (20), whether there is a requirement for preventing condensation or preventing icing at this place is determined, thereby being capable of effectively preventing the branching air supply device (20) from generating condensate and even preventing the condensate from being frozen into ice and improving the operational reliability of the branching air supply device (20), and thus also improving the overall refrigeration effect of the refrigerator (100).
