Description
Technical Field
The invention relates to the technical field of household appliances, in particular to a control method of a refrigerator.
Background
The refrigeration cycle loop of the conventional refrigerator is compressor → condenser → capillary → evaporator, and a common defrosting heating wire is installed at the bottom of the evaporator, when the evaporator needs defrosting, the compressor is stopped, the heating wire works, and the bottom heat is transferred to the top of the evaporator through the heat conduction and the heat radiation of the evaporator tube and the fin. The defrosting mode has the obvious defects that the efficiency of the defrosting heating wire is low, only about 20 percent of defrosting heating wire is applied to defrosting, other heat is radiated to the air duct, and therefore the temperature of the freezing chamber is greatly increased during defrosting, and the heat load of the refrigerator is large. A part of gas refrigerant in the evaporator enters the condenser through the capillary tube, and because the liquid refrigerant still remains in the condenser, the entering high-temperature gas refrigerant can be rapidly cooled into the liquid refrigerant, the unit volume is reduced, and most of the refrigerant remains, which is not beneficial to the refrigeration cycle. Similarly, in the traditional refrigerator with a series-parallel double-evaporator refrigerating system, the refrigerating evaporator is communicated with the freezing evaporator, and the refrigerant trend during refrigerating of the refrigerating chamber is as follows: compressor → condenser → three-way valve → refrigeration capillary → refrigeration evaporator → freezing evaporator, the refrigerant trend when the freezing chamber refrigerates is: compressor → condenser → three-way valve → refrigeration capillary → refrigeration evaporator. When the refrigeration evaporator defrosts, the refrigerant in the evaporator can be rapidly heated into high-temperature gas, one part of the high-temperature gas refrigerant enters the refrigeration evaporator along with a connecting pipe between the refrigeration evaporator and the refrigeration evaporator, and the other part of the high-temperature gas refrigerant enters the condenser through the refrigeration capillary and the three-way valve; when the freezing evaporator defrosts, the refrigerant in the evaporator can be heated into high-temperature gas rapidly, one part of the high-temperature gaseous refrigerant enters the refrigerating evaporator along with a connecting pipe between the refrigerating evaporator and the freezing evaporator, and the other part of the high-temperature gaseous refrigerant enters the condenser through the freezing capillary tube and the electromagnetic three-way valve, so that the refrigeration cycle is not facilitated.
Therefore, there is a need to provide an improved control method of a refrigerator to solve the above problems.
