Embodiment Construction
[0032] figure 1 is a schematic diagram of an air-cooled refrigerator according to an embodiment of the present invention; figure 2 is a schematic diagram of a refrigeration system of an air-cooled refrigerator according to an embodiment of the present invention; image 3 is a block diagram of an air-cooled refrigerator according to an embodiment of the present invention; Figure 4 is a schematic diagram of an air-cooled refrigerator control method according to an embodiment of the present invention; Figure 5 is a flow chart of an air-cooled refrigerator control method according to an embodiment of the present invention.
[0033] After analysis, it is found that the main reasons for the decrease in humidity in the refrigeration room are as follows. During the cooling process of the compressor, the air in the refrigeration room is cooled by the evaporator, and the moisture in the air in the refrigeration room condenses on the surface of the evaporator to form frost. Since ...

The invention provides an air-cooled refrigerator control method and an air-cooled refrigerator. The air-cooled refrigerator control method comprises the steps that after the temperature of a refrigeration chamber of the air-cooled refrigerator is reduced to a preset shutdown temperature, controlling a compressor of the air-cooled refrigerator to stop; acquiring the temperature of an evaporator of the air-cooled refrigerator; judging whether the temperature of the evaporator is greater than or equal to a first preset threshold; and if yes, controlling a refrigeration fan of the refrigeration chamber to operate, so that the humidity of the refrigeration chamber is improved through airflow flowing through the evaporator. The first preset threshold value is the lowest temperature at which water vapor of air in the refrigeration chamber does not separate out and crystallize any more when the air in the refrigeration chamber flows through the evaporator. Before the refrigeration fan operates, the temperature of the evaporator is judged firstly, and when the temperature of the evaporator reaches the first preset threshold value, the refrigeration fan operates. Therefore, the air flows through the evaporator again, the humidity of the air is increased, and the technical problem that the humidity of the refrigeration chamber is low is solved.
Description
technical field [0001] The invention relates to household refrigeration equipment, in particular to an air-cooled refrigerator control method and the air-cooled refrigerator. Background technique [0002] Fresh fruits and vegetables need a low-temperature and high-humidity environment during storage. Low-humidity environments can cause water loss or even wilting of fruits and vegetables. Low-humidity environments greatly affect the freshness of fruits and vegetables. Air-cooled refrigerators are refrigerated by sending cold air to the refrigerator's refrigeration compartment. The refrigeration compartment of the air-cooled refrigerator has the advantages of uniform temperature distribution, fast cooling speed, and no frost. , and even air-dried flaws. Contents of the invention [0003] An object of the present invention is to provide a control method for an air-cooled refrigerator and an air-cooled refrigerator, which are used to solve the technical problem of low humidit...
