Defrosting control method and device, refrigerator and computer readable storage medium

Abstract

The invention provides a defrosting control method and device, a refrigerator and a computer readable storage medium. The defrosting control method is suitable for the refrigerator and comprises the steps that when it is determined that a door of the refrigerator is opened or closed, a second preset defrosting period replaces an original first preset defrosting period, wherein the second preset defrosting period is shorter than the first preset defrosting period; the accumulative working time of the refrigerator after last defrosting operation is counted; and when the accumulative working timeis longer than or equal to the second preset defrosting period, defrosting operation is carried out, and the original first preset defrosting period is replaced with the original preset defrosting period. Through the technical scheme of the invention, the defrosting period is dynamically adjusted according to the door opening and closing situation in the actual using process of the refrigerator,on one hand, the phenomenon that the using performance of the refrigerator is damaged due to the fact that defrosting operation is not conducted while the frosting amount is too much is reduced, and on the other hand, the phenomenon that energy sources are wasted due to the fact that defrosting operation is conducted while the frosting amount is too little is reduced.

Description

technical field [0001] The present invention relates to the technical field of home appliance control, in particular to a defrosting control method, a defrosting control device, a refrigerator and a computer-readable storage medium. Background technique [0002] In related technologies, the defrosting cycle is generally shortened based on the duration of the previous defrosting operation, which has the following technical defects: [0003] (1) The start-up condition of defrosting operation is based on the accumulative door opening time reaching a certain length or the accumulative door opening and closing times reaching a certain value, which is not combined with the accumulative working time of the refrigerator, and the accuracy of variable defrosting is poor. [0004] (2) The defrosting cycle is shortened according to the duration of the last defrosting operation, and the number of door openings and closings in the shortened defrosting cycle is likely to be less, and when ...

AI Technical Summary

Problems solved by technology

[0003] (1) The defrosting operation starts with the accumulative door opening time reaching a certain time or the accumulative door opening and closing times reaching a certain value, which is not combined with the accumulative working time of the refrigerator, and the accuracy of changing defrosting is poor

[0004] (2) The defrosting cycle is shortened according to the duration of the last defrosting operation, and it is easy to cause fewer door opening and closing times in the shortened defrosting cycle. When the amount of frosting is small, the defrosting operation is performed, which wastes resources.
