Title:
REFRIGERATOR PROVIDED WITH MAGNETIC FIELD FRESHNESS-PRESERVING COMPARTMENT AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/231979
Kind Code:
A1
Abstract:
The present invention provides a control method for a refrigerator provided with a magnetic field freshness-preserving compartment. The refrigerator comprises a refrigerator body and a refrigeration air duct. A freezing compartment and a magnetic field freshness-preserving compartment are defined in the refrigerator body, and the refrigeration air duct extends from the freezing compartment to the magnetic field freshness-preserving compartment and is provided with a freshness-preserving damper. An evaporator and a fan are arranged inside the part of the refrigeration air duct located inside the freezing compartment. In addition, the control method comprises: once refrigeration of the refrigerator is started, obtaining the temperature of the magnetic field freshness-preserving compartment; controlling the opening and closing of the freshness-preserving damper according to the temperature of the magnetic field freshness-preserving compartment; obtaining the temperature of the evaporator when the freshness-preserving damper is in an open state; and controlling an operation mode of the fan according to the temperature of the evaporator. According to the solution of the present invention, the freezing of a stored object caused by an excessively low temperature of a refrigeration airflow can be prevented, thereby effectively improving the freshness-preserving storage quality.
