the temperature of the chamber of the evaporator is too low, about-20 ℃, the temperature of the evaporator is about-12 ℃ after the evaporator is directly sent to the refrigerating chamber through the freezing fan, the air supply temperature is far lower than 0 ℃, and the evaporator directly blows the air to the surfaces of foods with rich water content, such as fruits and vegetables in the refrigerating chamber, so that the foods are frozen and necrotized, the foods deteriorate, and the fresh-keeping function of the refrigerating chamber of the refrigerator is seriously influenced.
Secondly, the cold air far below 0 ℃ causes uneven temperature distribution of the refrigerating chamber, and the temperature difference of different areas in the refrigerating chamber and the freezing chamber is large, so that the temperature uniformity of the refrigerating chamber and the freezing chamber is poor.
And the temperature of the sensors of the refrigerating chamber and the freezing chamber is inaccurate due to overlarge deviation of the air supply temperature and the temperatures of the refrigerating chamber and the freezing chamber, so that the temperature control of the refrigerating chamber and the freezing chamber is possibly deviated, and the temperature control is inaccurate.
And fourthly, when the air supply temperature of the refrigerating chamber and the refrigerating chamber is too low, so that the air supply and the air of the refrigerating chamber cannot be fully mixed, cold air reaches the bottom of the refrigerating chamber and is continuously accumulated, the air temperature at the bottom of the refrigerating chamber is lower than 0 ℃, the food stored at the bottom of the refrigerating chamber is frozen, and the use experience of a user is seriously influenced.
Through the above analysis, the problems and defects of the prior art are as follows:
(1) in the prior art, the control precision of the temperature of the refrigerating chamber is low, the temperature stability of the refrigerating chamber is poor, and the fresh-keeping effect of the refrigerating chamber is poor.
(2) The prior art wind temperature control can not avoid the phenomenon that the freezing phenomenon that the lower temperature of the refrigerating chamber is lower than 0 ℃ and the reliability of a refrigerating appliance is poor due to the fact that the cold quantity at the bottom of the refrigerating chamber is accumulated and the freezing phenomenon that the lower temperature of the refrigerating chamber is lower than 0 ℃ can not be avoided.
(3) In the prior art, the refrigerating appliance runs stably and is not opened or closed, the gas mobility in the refrigerating chamber is relatively low, the internal circulation is weak, cold circulation is carried out by a single fan of the freezing chamber, the temperature uniformity of the refrigerating chamber is poor, most cold quantity of the refrigerating chamber and the freezing chamber sinks to the bottom for deposition, and then the evaporator chamber is returned to without circulation, so that the utilization rate of the cold quantity is low.
The difficulty in solving the above problems and defects is: how to realize the mixing of the freezing air supply and the refrigerating return air, the air supply temperature of the refrigerating chamber is improved, and the influence of cold damage on food is avoided; how to realize the improvement of the temperature uniformity of the refrigerating chamber; how to utilize the cold energy deposited on the bottommost layer of the refrigerating chamber and improve the utilization rate.

the cold energy introduced into the cavity of the evaporator is controlled and simultaneously mixed with the return air of the refrigerating chamber, so that the air supply temperature of the refrigerating chamber is reduced;
the air supply of the refrigerating chamber is controlled within the optimal temperature range by controlling the opening of the freezing air door.
9. An information data processing terminal characterized by comprising a memory and a processor, the memory storing a computer program that, when executed by the processor, causes the processor to perform the steps of:
the cold energy introduced into the cavity of the evaporator is controlled, and simultaneously, the cold energy is controlled to be mixed with the return air of the refrigerating chamber, so that the air supply temperature of the refrigerating chamber is reduced;
the air supply of the refrigerating chamber is controlled within the optimal temperature range by controlling the opening of the freezing air door.
10. A computer-readable storage medium storing a computer program which, when executed by a processor, causes the processor to perform the steps of:
the cold energy introduced into the cavity of the evaporator is controlled and simultaneously mixed with the return air of the refrigerating chamber, so that the air supply temperature of the refrigerating chamber is reduced;
the air supply of the refrigerating chamber is controlled within the optimal temperature range by controlling the opening of the freezing air door.
