Title:
REFRIGERATOR AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/049962
Kind Code:
A1
Abstract:
A Refrigerator and control method therefor. A refrigerator (10) comprises a refrigerating chamber (610), a freezing chamber (620) and a refrigerating system (100). A control method of the refrigerator comprises: on the basis of set temperatures of the refrigerating chamber (610) and the freezing chamber (620), respectively calculating respective lower temperature limits therefor; obtaining the current temperature of the refrigerating chamber (610); judging whether the current temperature of the refrigerating chamber (610) is higher than the lower temperature limit of the refrigerating chamber (610) or not; if the current temperature of the refrigerating chamber (610) is higher than the lower temperature limit of the refrigerating chamber (610), adjusting operating parameters of the refrigerating system (100) so that the refrigerating system operates in a first operating mode; if the current temperature of the refrigerating chamber (610) is not higher than the lower temperature limit of the refrigerating chamber (610), directly obtaining the current temperature of the freezing chamber (620); judging whether the current temperature of the freezing chamber (620) is higher than the lower temperature limit of the freezing chamber (620) or not; if the current temperature of the freezing chamber (620) is higher than the lower temperature limit of the freezing chamber (620), adjusting operating parameters of the refrigerating system (100) so that the refrigerating system operates in a second operating mode; if the current temperature of the freezing chamber (620) is not higher than the lower temperature limit of the freezing chamber (620), directly judging whether the current temperatures of the refrigerating chamber (610) and the freezing chamber (620) are both lower than the corresponding lower temperature limits or not; if the current temperatures of the refrigerating chamber and the freezing chamber are both lower than the corresponding lower temperature limits, stopping the operation of the refrigerating system (100); and if the current temperatures of the refrigerating chamber and the freezing chamber are not both lower than the corresponding lower temperature limits, returning back to obtain the current temperature of the refrigerating chamber (610). A refrigerator (10) is also provided comprising a temperature sensor component (200) and a control device (300).
