Title:
CONTROL METHOD FOR REFRIGERATOR, AND REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2021/244077
Kind Code:
A1
Abstract:
Provided are a control method for a refrigerator and the refrigerator. The control method comprises: ending a deep cooling mode for operating a first evaporator so as to increase the temperature in a first storage chamber; and controlling an on-off device to turn on a communicating air duct, so that gas in a second storage chamber enters the first storage chamber. Because of the provision of the communicating air duct and the on-off device, once the first storage chamber exits the deep cooling mode, a deep cooling chamber may be quickly switched back to an ordinary chamber without adding additional power consumption to achieve a rapid rise in the temperature of the deep cooling chamber. Specifically, when the deep cooling chamber exits, a deep cooling compressor stops operating. At said time, an air door is opened. Since the deep cooling chamber is in a negative pressure state (low temperature and little pressure), air in other chambers flows to the deep cooling chamber. The air in the chambers is mixed to achieve a rapid rise in the temperature of the deep cooling chamber without external heating.
