冰箱及其控制方法
By installing temperature sensors at the top and bottom of the refrigerator compartment, calculating the temperature difference, and combining this with damper adjustment and fan control, the problem of abnormal cooling caused by single-point temperature measurement in frost-free refrigerators is solved. This achieves precise temperature control of the refrigerator compartment and autonomous fault handling, improving the accuracy of refrigerator cooling status judgment and operational reliability.

AI Technical Summary
Existing air-cooled refrigerators only have a single temperature detection point in the refrigerator compartment, which cannot fully reflect the actual temperature distribution in the upper and lower areas of the refrigerator compartment. This results in the inability to identify and adjust in time when there is a cooling malfunction, affecting the temperature control effect of the refrigerator compartment and the quality of food storage.
Temperature sensors are installed at the top and bottom of the refrigerator compartment. The refrigeration condition is determined by calculating the temperature difference. Combined with damper adjustment, fan speed adjustment and defrosting program, the refrigerator compartment can be accurately controlled and faults can be identified.
By employing a dual temperature difference determination method, the refrigerator can accurately identify normal and abnormal refrigeration conditions, optimize the temperature control performance of the refrigerator cavity, ensure temperature uniformity in the refrigerator cavity and the preservation effect of food, and improve the stability and reliability of refrigerator operation.
