Problems solved by technology

[0003] At present, air-cooled refrigerators usually have the following problems: 1) The operation mode of the refrigerator is single, the energy-saving effect is poor, and the temperature control accuracy is low; 2) When cooling the refrigerator, the high-temperature return air from the refrigerator enters the freezer, 3) When a large number of high-temperature items are placed in the refrigerator or freezer, the load of the refrigerator or freezer is high (that is, the temperature is much higher than the starting point), and the refrigerator The control process is the same during normal start-up and high load, not only cannot quickly lower the temperature under high load, causing the food to be suddenly exposed to high temperature, causing food to deteriorate and rot, but also high energy consumption; 4) The moisture loss in the refrigerator room causes air-drying problems; 5 ) Due to the frequent opening of the door of the refrigerator room, the door body has not been closed tightly. At this time, the long-term operation of the refrigeration system may easily lead to damage

Abstract

The invention discloses an air-cooling refrigerator and an operation control method thereof. The method comprises the steps of collecting the temperature Tf of a freezing chamber and the temperature Tr of a refrigerating chamber in real time; judging whether either or both of a first preset condition and a second preset condition are met or not, wherein the first preset condition is that the temperature Tr corresponds to a refrigerating starting preset temperature interval, and the second preset condition is that the temperature Tf corresponds to a freezing starting preset temperature interval; when either or both of the first preset condition and the second preset condition are met, judging whether either or both of a third preset condition and a fourth preset condition are met or not, wherein the third preset condition is that the temperature Tr corresponds to a refrigerating first preset temperature interval, and the fourth preset condition is that the temperature Tf corresponds to a first preset temperature internal; when either or both of the third preset condition and the fourth preset condition are met, controlling the refrigerator to implement the high loading mode; and when neither of the third preset condition and the fourth preset condition is met, controlling the refrigerator to implement the constant temperature mode.

Description

technical field [0001] The invention relates to an air-cooled refrigerator and an operation control method thereof, belonging to the technical field of household appliances. Background technique [0002] At present, with the improvement of the quality of life, people have more and more stringent requirements on the freshness preservation ability of refrigerators. As the two storage rooms that are commonly used in refrigerators, the stability and accuracy of their temperature have greatly affected The storage quality of food in the refrigerator. [0003] At present, air-cooled refrigerators usually have the following problems: 1) The operation mode of the refrigerator is single, the energy-saving effect is poor, and the temperature control accuracy is low; 2) When cooling the refrigerator, the high-temperature return air from the refrigerator enters the freezer, 3) When a large number of high-temperature items are placed in the refrigerator or freezer, the load of the refrig...
