Abstract

The invention discloses a refrigerator and a self-adaption defrosting control method thereof. A defrosting control device is adopted for monitoring the defrosting interval time and the actual accumulative door opening time of a current defrosting interval period; the defrosting interval time is compared with a maximum defrosting interval time preset value; if the defrosting interval time is larger than or equal to the maximum defrosting interval time preset value, defrosting is started, and otherwise, the actual accumulative door opening time is compared with the preset accumulative door opening time kT[i] of the current defrosting interval period; if the actual accumulative door opening time is larger than or equal to the preset accumulative door opening time kT[i], defrosting is started, and the time ht from defrosting starting to defrosting ending is monitored; and after defrosting ends, ht is compared with a defrosting time preset value hT so that the preset accumulative door opening time kT[i+1] of a next defrosting interval period can be obtained.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a refrigerator and an adaptive defrosting control method thereof. Background technique [0002] There are many ways to control the defrosting of air-cooled refrigerators, such as using a fixed time to defrost, which cannot be changed according to the actual situation; Frost, this method may cause defrosting when the amount of frosting is insufficient, increasing energy consumption. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the prior art cannot adjust the defrosting cycle according to the actual use of the refrigerator. [0004] In order to achieve the purpose of the above invention, the present invention provides an adaptive defrosting control method for a refrigerator, including: [0005] S1. Monitor the defrosting interval time and the actual accumulated door opening time of the current d...
