Air-cooled refrigerator and its operation control method

Abstract

The invention discloses an air cooling refrigerator and a running control method thereof. The method comprises the steps that the refrigerator is controlled to be in the refrigeration state, and time t of the refrigerator in the refrigeration state is subject to synchronized statistics operation, wherein the refrigeration state comprises refrigeration system starting, draught fan starting, frozen air door closing and refrigeration air door opening; the temperature Tr of a refrigerating chamber is collected, whether the temperature Tr corresponds to the fourth refrigeration preset temperature section or not is judged, and whether time t reaches the first preset time or not is judged; when the temperature Tr does not correspond to the fourth refrigeration preset temperature section all the time from the time t to the first preset time t1, the refrigerator is controlled to execute the abnormal mode. When the abnormal condition that a refrigeration chamber runs for a long time and cannot reach the shutdown point happens, the running process is reasonably controlled, and damage and energy losses caused by long-time starting are avoided.

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...

AI Technical Summary

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
