Refrigerator fan ice blockage control method, refrigerator and computer storage medium

Abstract

The invention provides a refrigerator fan ice blockage control method, a refrigerator and a computer storage medium. The refrigerator fan ice blockage control method is characterized by comprising the following steps that after it is judged that a fan is in an abnormal state, the fan is turned on and off repeatedly; if the fan is still in an abnormal operation state after the repeated starting times of the fan reach the first maximum trial starting times, a defrosting heating device is started until the temperature reaches a first forced defrosting stop temperature; after defrosting is stopped, the fan is turned on and turned off repeatedly again; and if the fan is still in the abnormal operation state after the repeated starting times in the process that the fan is repeatedly turned on and off again reach the second maximum trial starting times, the defrosting heating device is started to reach a second forced defrosting stop temperature. The problem of ice blockage caused by freezing of condensed water in the fan of the air-cooled refrigerator is effectively solved in a mechanical physical and defrosting heating combined mode, the efficiency of solving the ice blockage can be improved through the step-by-step flow steps, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of refrigeration devices, in particular to a method for controlling ice blockage of a fan of a refrigerator, a refrigerator and a computer storage medium. Background technique [0002] The air-cooled refrigeration device uses circulating cold air for refrigeration. Compared with the traditional direct-cooled refrigeration device, it has the advantages of no frost, fast cooling speed, and uniform temperature. [0003] For air-cooled refrigerators, any components including evaporators, air ducts, fans, etc. in the low-temperature cabinet at minus ten degrees or even minus tens of degrees may cause the problem of condensed water freezing. Icing of the evaporator and the air duct will seriously affect the cooling effect. The freezing of the fan may cause the fan to stall, greatly reduce the cooling capacity in the box, and even cause the frozen items in the box to heat up and thaw and deteriorate. For the machine, an alar...

AI Technical Summary

Problems solved by technology

Icing of the evaporator and the air duct will seriously affect the cooling effect. The freezing of the fan may cause the fan to stall, greatly reduce the cooling capacity in the box, and even cause the frozen items in the box to heat up and thaw and deteriorate. For the machine, an alarm message will be generated. , reducing customer experience

[0004] The existing technical solution judges that the fan is blocked by identifying the abnormal speed of the fan, and solves the ice blockage by defrosting and heating. However, the current method only solves the ice blockage by repeating the same defrosting and heating steps many times. , high energy consumption, low efficiency, and the lack of corresponding control and detection methods, it is easy to cause damage to the fan
