Abstract
The present disclosure provides a refrigerator operation control method capable of accurately recognizing whether an abnormal situation occurs as well as determining a defrosting time using an identified rotation speed of a blowing fan.
Claims22
An operation control method of a refrigerator comprising:
- a cooling operation step of providing heat-exchanged cooling air to a storage compartment in front of a grille assembly by passing through a cooling source located in the rear of the grille assembly;
- a heat supply operation step of providing heat to the cooling source;
- an abnormality determination step of checking a rotation speed of a blowing fan located in the grille assembly and determining an occurrence of an abnormal situation or a type of an abnormal situation based on the checked rotation speed of the blowing fan;
- and
- an abnormality resolving step of performing at least one step or control among the cooling operation step, the heat supply operation step, or a control for solving the occurrence of the abnormal situation or the type of the abnormal situation identified by the determination of the abnormality determination step,
- wherein in the abnormality determination step, at least one of the following processes is performed:
- a rotation speed checking process of checking the rotation speed of the blowing fan;
- a speed change checking process of checking whether the rotation speed changes from a reference rotation speed and, checking the changed speed if there is a change in the rotation speed;
- a speed range checking process of checking a speed range to which the identified changed speed belongs among two or more plurality of speed ranges including a first speed range;
- and
- an abnormality determination process of determining whether a load occurs on an air inlet side of the blowing fan or a load occurs on an air outlet side of the blowing fan according to the speed range to which the changed speed belongs.
