Description

Refrigerator control method and device, refrigerator and computer storage medium Technical Field The disclosure relates to the field of refrigerators, and in particular relates to a refrigerator control method and device, a refrigerator and a computer storage medium. Background In the working process of the frostless refrigerator, the evaporator in the refrigerator can be frosted at regular intervals. In the defrosting process, a defrosting heating wire in the refrigerator works to generate heat so as to melt frost. Therefore, the temperature in the refrigerator compartment is greatly raised during the defrosting process. In the related art, in order to rapidly decrease the temperature in the refrigerator compartment at the temperature pulling stage after the defrosting is completed, it is generally adopted to start the compressor to generate cold by the operation of the compressor. However, if the compressor is continuously operated at a high speed, a large noise is generated, thereby causing trouble to the life of the user. If the compressor runs at a low speed, although the generated noise is small, the refrigerating effect is slow, and the temperature in the refrigerator compartment cannot be reduced in time, so that the fresh-keeping effect of the refrigerator is affected. The above information disclosed in the background section is only for enhancement of understanding of the background of the disclosure and therefore it may include information that does not form the prior art that is already known to a person of ordinary skill in the art.

According to one aspect of the present disclosure, there is provided a refrigerator control apparatus including: The compressor control module is used for starting the compressor after defrosting treatment so as to reduce the temperature in the refrigerator compartment; The temperature monitoring module is used for monitoring the room temperature in the refrigerator room; and the compressor rotating speed adjusting module is used for adjusting the down-regulating quantity of the rotating speed of the compressor according to the reduction degree of the temperature of the compartment. According to another aspect of the present disclosure, there is provided a refrigerator including: A storage unit storing a refrigerator control program; And the processing unit is used for executing the steps of the refrigerator control method when the refrigerator control program is run. According to the technical scheme, in the temperature pulling stage after defrosting is finished, the reduction amount of the rotating speed of the compressor is adaptively adjusted according to the reduction degree of the temperature of the refrigerator compartment, so that the rotating speed of the compressor can be optimized on the premise of meeting the refrigerating demand, noise generated by the compressor is reduced, and the use experience of a user is improved.
