Abstract

The invention provides a method for controlling a refrigerator with fan shield and the refrigerator. The refrigerator comprises a freezing chamber, a refrigerating chamber, a refrigeration system and a control system, wherein the refrigeration system comprises a press, an evaporator, an air duct, a fan, a refrigerating air door and fan shield correspondingly arranged with the fan; the fan shield is used for adjusting the air output of the freezing chamber during the operation of the fan, and the fan shield is provided with closing, opening and multiple semi-opening gears. The control method comprises the following steps: detecting real-time temperatures T1 and T2 of the freezing chamber and the refrigerating chamber, controlling the opening and closing of the fan and the refrigerating air door in combination with target temperatures T1 'and T2' and according to a freezing temperature difference delta T1 and a refrigerating temperature difference delta T2, and determining to open, close or open the fan shield to a certain semi-opening gear. By adoption of the control method and the refrigerator, the air output of the refrigerating chamber and the freezing chamber are controlled and allocated more reasonably, the refrigeration process of the refrigerating chamber and the freezing chamber is optimized, the refrigeration effect of the refrigerator is improved, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerator control, in particular to a method for controlling a refrigerator with fan shielding and the refrigerator. Background technique [0002] At present, when the single-system air-cooled refrigerator is working, if the temperature of the freezer or refrigerator is detected to be higher than the set temperature, the compressor and the fan are controlled to start cooling, and the opening and closing of the refrigerator damper is controlled by judging whether the temperature of the refrigerator is higher than the set temperature . Continuous refrigeration in the freezer is not conducive to the improvement of refrigeration efficiency, and the energy consumption will increase accordingly. In addition, when the evaporator defrosts, the temperature of the above-mentioned freezing chamber rises significantly, which is not conducive to food storage. A refrigerator with a fan shield has been disclosed in...
