Refrigerator control method and refrigerator using the same

Abstract

The present invention provides a control method for a refrigerator, comprising the following steps: after the last defrosting program ends, based on the operating conditions of the refrigerator before the last defrosting program ends, the initial defrosting interval time for starting the next defrosting program is determined ; Based on the operation and use status of the refrigerator after the end of the last defrost program, correct the initialization frost interval time to obtain the corrected actual defrost interval time; determine whether the elapsed time since the end of the last defrost program has expired When the corrected actual defrosting interval is reached, if the elapsed time from the end of the last defrosting procedure has reached the corrected actual defrosting interval, the next defrosting procedure will be started. The refrigerator can start the defrosting program at the time when defrosting is really needed, saving energy and ensuring the refrigeration efficiency of the refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a household refrigerator and a control method thereof. Background technique [0002] During the use of household refrigerators, it is inevitable that frost will form on the evaporators of the refrigerator and freezer, so it is necessary to periodically start the heater installed on the evaporator to defrost the evaporator, and pass the defrosted water through the drain pipe discharge. Accordingly, the operation control of the refrigerator includes a refrigerating cycle for cooling the storage compartment and a defrosting cycle for defrosting the evaporator. [0003] In the prior art, refrigerators usually perform defrosting operations at fixed defrosting intervals. Due to the great difference between the use environment of the refrigerator and the user's use of the refrigerator, the actual frosting conditions of the refrigerator are also very different. The fixed defrost...
