The storage room in step S11 of the present invention refers to the freezing chamber.
The ring temperature range is 18-45 ℃, and the ring temperature range is divided into three temperature levels in advance, wherein the three temperature levels are respectively: first temperature level: 18-28 ℃, and the second temperature grade: 28-35 ℃, third temperature grade: 35-45 ℃. The first rotating speed corresponding to the first temperature level is 3000, the first rotating speed corresponding to the second temperature level is 4020, and the first rotating speed corresponding to the third temperature level is 4410.

The second rotation speed corresponding to the first temperature level is 2010, the second rotation speed corresponding to the second temperature level is 3000, and the second rotation speed corresponding to the third temperature level is 4020.

after the refrigerator finishes a defrosting program, when detecting that the door of the freezing chamber is not opened, controlling the compressor to operate according to a normal rotating speed, wherein the normal rotating speed is smaller than the first rotating speed;
after the compressor is controlled to run at a preset first rotational speed, judging whether a stop time point of the compressor is reached, and maintaining a stop state of the compressor in a preset first stop time period;
if so, controlling the compressor to operate at a preset second rotating speed, wherein the second rotating speed is smaller than the first rotating speed; if not, controlling the compressor to operate according to the first rotating speed; wherein the second rotational speed is determined from the ambient temperature; wherein each temperature grade has a corresponding second rotating speed;
after controlling the compressor to operate at a preset second rotating speed, judging whether a shutdown time point of the compressor is reached within a preset second shutdown time period;
if yes, acquiring the accumulated running time of the refrigerator; and if not, controlling the compressor to operate according to the first rotating speed.
5. The refrigerator control method as claimed in claim 4, wherein after the acquiring the accumulated operation time of the refrigerator, the method further comprises:
and executing a defrosting program when the accumulated running time is larger than a preset running time threshold value.
