Problems solved by technology

To sum up, after the refrigeration of the refrigerator is completed, neither the cooling capacity nor the air volume in the refrigerator can be maintained.
Therefore, the energy consumption of this refrigerator is relatively high, and the refrigeration is uneven, and it is impossible to keep food fresh for a long time

Abstract

The invention discloses a control method for the environment in the refrigerating chamber of a refrigerator. The refrigerator comprises a box body and a refrigerating system, the box body comprises the refrigerating chamber and an evaporator cavity, the refrigerating system comprises a compressor, an evaporator arranged inside the evaporator cavity, an air inlet air passage for communicating the refrigerating chamber and the evaporator cavity, and an air return air passage; an air return air door is arranged between the air return air passage and the refrigerating chamber; the control method comprises the following steps: a, detecting the temperature of the refrigerating chamber repeatedly until the temperature of the refrigerating chamber is lower than or equal to a first preset temperature threshold value; b, detecting the humidity of the refrigerating chamber repeatedly until the humidity of the refrigerating chamber is smaller than or equal to a first preset humidity threshold value; and c, closing the air return air door. The control method provided by the invention ensures that energy consumption of the refrigerator is low, even refrigeration is achieved, and the freshness of foods in the refrigerating chamber can be effectively kept.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a method for controlling the environment of a cold room of a refrigerator. Background technique [0002] At present, the design of the refrigerator is that the cold air entering the refrigerator is controlled by the air intake door, but the return air of the refrigerator is naturally circulated by the system pressure. In this way, when the temperature of the refrigerator compartment is reached, the air intake door is closed, and the wind in the refrigerator chamber will continue to return to the evaporator chamber due to the pressure difference. At the same time, because there is no forced circulation of wind in the refrigerating room, the pressure in the refrigerating room decreases, and the hot air outside the refrigerator enters the refrigerating room through the door seal, which makes the temperature of the refrigerating room rise. The room starts to cool again. To sum up, after t...
