Refrigerator defrosting control method

Abstract

The invention relates to a refrigerator control method, and particularly relates to a refrigerator defrosting control method. The invention provides a refrigerator defrosting control method which aims to overcome the irrationality of the defrosting control method in the prior art. Hardware foundations of the refrigerator defrosting control method comprise a temperature sensor, a microcontroller, a drive chip, a relay and a defrosting heater. The defrosting control method is characterized in that a temperature fall value of a freezing chamber in unit time is used as a judgment foundation for the start of the defrosting heater, thereby reducing unnecessary defrosting and inopportune defrosting, and ensuring that the refrigerator is always in an optimal refrigeration state.

Description

technical field [0001] The present invention relates to a control method of a refrigerator, and more specifically relates to a defrosting control method of a refrigerator. Background technique [0002] Existing defrosting is generally based on the cumulative working time of the compressor to determine whether to wake up and defrost. The interval between defrosting and defrosting is fixed or relatively fixed; It has an impact on the defrosting control system, which has caused two problems, either unnecessary defrosting, resulting in a waste of energy, or defrosting is not timely, resulting in poor cooling effect of the refrigerator. Not only that, because the defrosting time will be re-timed after the breakpoint of the existing refrigerator, it is also very easy to cause untimely defrosting. Generally speaking, in the prior art, because the frosting amount of the evaporator of the refrigerator cannot be judged, unnecessary or untimely defrosting occurs, resulting in waste of...

Not only that, because the defrosting time will be re-timed after the breakpoint of the existing refrigerator, it is also very easy to cause untimely defrosting

Generally speaking, in the prior art, due to the inability to judge according to the frosting amount of the refrigerator evaporator, there will be unnecessary or untimely defrosting, resulting in waste of energy and poor refrigeration of the refrigerator.
