and if the difference is smaller than the threshold value, acquiring the temperature information of the first chamber and the temperature information of the second chamber which is not cooled currently.
5. A compressor control device is characterized by comprising: at least two compartments, and a refrigerator having a compressor for separately cooling each of the compartments, the apparatus comprising:
an obtaining module, configured to obtain temperature information of a first compartment and temperature information of a second compartment that is not currently cooled during operation of the compressor in response to a first compartment cooling request, where the temperature information of the first compartment includes: the current temperature value of the first chamber and the shutdown temperature value corresponding to the first chamber, and the temperature information of the second chamber comprises: the current temperature value of the second chamber and the starting temperature value corresponding to the second chamber;
the judging module is used for acquiring the cooling rate of the first chamber and the heating rate of the second chamber, determining the shutdown time corresponding to the first chamber according to the current temperature value, the cooling rate and the shutdown temperature value of the first chamber, determining the startup time corresponding to the second chamber according to the current temperature value, the heating rate and the startup temperature value of the second chamber, and determining that a preset continuous operation condition is met if the startup time is within a preset time period after the shutdown time;
the control module is used for controlling the compressor to continue to operate without stopping after the operation responding to the first compartment cooling request is finished when the preset continuous operation condition is met;
and the control device is also used for controlling the compressor to stop after the operation responding to the first compartment cooling request is finished when the preset continuous operation condition is not met.
6. A non-transitory computer readable storage medium storing computer instructions for implementing compressor control, the computer instructions causing the computer to perform the steps of the compressor control method of any of claims 1-4.
