Refrigeration temperature control refrigerator and method, refrigerator, controller, terminal and storage medium

Abstract

The invention belongs to the technical field of refrigerators, and discloses a refrigeration temperature control refrigerator, a method, a refrigerator, a controller, a terminal and a storage medium.Cold energy of an evaporator chamber is introduced, and meanwhile mixed with return air of a refrigerating chamber; the supply air temperature of the refrigerating chamber is reduced; and the air supply of the refrigerating chamber is controlled within the optimal temperature range through regulation of the opening degree of a freezing air door. According to the refrigeration temperature control refrigerator, through a brand-new air supply mode, it is guaranteed that the air supply temperature of the refrigerating chamber is the optimal air supply temperature required for the refrigerating chamber and the freezing chamber, and the temperature control precision of the refrigerating chamber is improved, and the temperature stability of the refrigerating chamber is improved; and the temperature fluctuation of the refrigerating chamber is reduced, and the fresh-keeping effect of the refrigerating chamber is improved. Through optimal control over the air temperature, the situation that theair with the temperature of far lower than 0 DEG C is directly blown to the refrigerating chamber and consequently food is frozen and frostbitten is avoided, meanwhile the icing phenomenon that the temperature of the lower portion of the refrigerating chamber is lower than 0 DEG C due to cold accumulation at the bottom of the refrigerating chamber is avoided, and reliability of the refrigerator isimproved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a refrigerated and temperature-controlled refrigerator, a method, a refrigerator, a controller, a terminal and a storage medium. Background technique [0002] At present, the method for controlling the temperature of the refrigerating chamber of a refrigerator usually adopts the direct air supply mode of the refrigerating fan, and the cooling capacity in the evaporator chamber is directly sent to the refrigerating chamber through the air door, thereby controlling the temperature of the refrigerating chamber. However, this conventional refrigerator The refrigeration temperature control method has the following problems: [0003] ① The chamber temperature of the evaporator is too low, about -20°C, and the temperature is about -12°C after being sent directly to the refrigerator by the freezing fan. Vegetables and other water-rich food surfaces will cause food to f...

AI Technical Summary

Problems solved by technology

[0003] ① The chamber temperature of the evaporator is too low, about -20°C, and the temperature is about -12°C after being sent directly to the refrigerator by the freezing fan. The surface of food with rich water content, such as vegetables, will cause the food to freeze and die, and then cause food to deteriorate, seriously affecting the fresh-keeping function of the refrigerator freezer

[0004] ②The cold wind far below 0°C will lead to uneven temperature distribution in the refrigerating room, and the temperature difference between different areas in the refrigerating room and freezing room is large, resulting in poor temperature uniformity between the refrigerating room and freezing room

[0005] ③Excessive deviation between the air supply temperature and the temperature of the refrigerator and freezer leads to inaccurate temperature collection of the sensors in the refrigerator and freezer, which may lead to deviations in the temperature control of the refrigerator and freezer, resulting in inaccurate temperature control

[0006] ④The temperature of the supply air in the refrigerator and freezer is too low, so that when the supply air and the air in the refrigerator cannot be fully mixed, the cold air has reached the bottom of the refrigerator and continues to accumulate, causing the air temperature at the bottom of the refrigerator to be lower than 0°C
