Along with the popularization of the frequency conversion technology, the frequency conversion technology is gradually applied to the field of refrigerators, and compared with the traditional fixed frequency refrigerator, the frequency conversion refrigerator has the advantages of low energy consumption, low noise and the like, so that the frequency conversion refrigerator is more and more widely applied.
In the frequency conversion refrigerator, the working power of the frequency conversion compressor can be changed according to the rotation speed of the compressor, the state of the refrigerator, the number of articles placed in the refrigerator and the like. The more stable the working power of the inverter compressor is, the better the operating power of the inverter compressor is, that is, when the refrigerator is in a relatively stable external environment, the power of the inverter compressor is maintained at a stable value, and the operating power of the inverter compressor is not only as stable as possible but also can meet the refrigeration requirements of users in the current environment and the current load. For example, when the ambient temperature is high, the operation power of the inverter compressor of the refrigerator is higher than that of the inverter compressor when the ambient temperature is low, so as to meet the refrigeration requirement of a user; when the refrigerator is in a low-temperature environment, although the high running power of the inverter compressor can meet the refrigeration requirement, the power consumption of the refrigerator is higher, so that the running power of the inverter compressor is lower, and the energy and the power are saved while the refrigeration requirement of a user is met.

in step S329, if the third rotation speed is greater than the minimum rotation speed, the rotation speed of the compressor is adjusted based on the third rotation speed.
In this embodiment, a corresponding rotation speed range is preset for each preset power range, that is, a maximum rotation speed and a minimum rotation speed are set, the maximum rotation speed is the maximum rotation speed at which the compressor can normally operate, the minimum rotation speed is the minimum rotation speed at which the compressor can normally operate, and the maximum rotation speed is greater than the minimum rotation speed.
When the third rotating speed is obtained, whether the third rotating speed is greater than the maximum rotating speed is determined, when the third rotating speed is less than or equal to the maximum rotating speed, whether the third rotating speed is less than or equal to the minimum rotating speed corresponding to the preset power range is determined, when the third rotating speed is greater than the minimum rotating speed, the rotating speed of the compressor is adjusted based on the third rotating speed, the rotating speed of the compressor is adjusted to the third rotating speed, namely, whether the third rotating speed is in the rotating speed range corresponding to the maximum rotating speed and the minimum rotating speed is determined, and when the third rotating speed is in the rotating speed range corresponding to the maximum rotating speed and the minimum rotating speed, the rotating speed of the compressor is adjusted based on the third rotating speed. And if the third rotating speed is less than or equal to the maximum rotating speed and less than or equal to the minimum rotating speed, adjusting the rotating speed of the compressor based on the minimum rotating speed, namely directly adjusting the minimum rotating speed to the rotating speed of the compressor.
Further, in an embodiment, after step S326, the method further includes: when the third rotational speed is greater than or equal to the maximum rotational speed, adjusting the rotational speed of the compressor based on the maximum rotational speed.
In this embodiment, when the third rotation speed is greater than or equal to the maximum rotation speed, the third rotation speed after the rotation speed of the compressor is reduced is still higher, and at this time, the rotation speed of the compressor is adjusted based on the maximum rotation speed, that is, the maximum rotation speed is directly adjusted to the rotation speed of the compressor.
In the control method for the refrigerator according to this embodiment, when the power of the compressor is less than the minimum preset power corresponding to the preset power range, the current rotation speed of the compressor is increased to a third rotation speed based on a second preset rotation speed, then it is determined whether the third rotation speed is greater than or equal to the maximum rotation speed corresponding to the preset power range, and then when the third rotation speed is less than the maximum rotation speed, it is determined whether the third rotation speed is less than or equal to the minimum rotation speed corresponding to the preset power range, if so, the rotation speed of the compressor is adjusted based on the minimum rotation speed, otherwise, the rotation speed of the compressor is adjusted based on the third rotation speed, so that the power of the compressor can be accurately adjusted when the power of the compressor is less than the minimum preset power, gradual adjustment of the power of the compressor is achieved, and the situation that the power of the compressor changes greatly is avoided, the power of the compressor can be changed stably, so that the energy consumption of the refrigerator can be reduced, and the temperature of the compartment of the refrigerator can be changed stably.
