Example Embodiment

[0031] Example one

[0032] The embodiment of the present invention provides a refrigerator 10, which combines figure 1 As shown, the refrigerator 10 includes a refrigerating compartment, a freezing compartment, a controller 101, a compressor 102, and an evaporator 103.

[0033] A first temperature sensor 104 is installed in the freezer compartment, and the first temperature sensor 104 is used to measure the temperature value TF in the freezer compartment.

[0034] Combine figure 2 As shown in the side view of the refrigerating compartment, the back plate 109 of the refrigerator 10 is attached to one side of the insulation layer 110, and the other side of the insulation layer 110 is attached to the evaporator 103 ( figure 2 Not marked in). One side of the heat exchange plate 1031 of the evaporator 103 is attached to the inner liner 111 of the back of the refrigerating compartment, and the other side is installed with a compensation heater 105 and a second temperature sensor 106, th...

Example Embodiment

[0060] Example two

[0061] The second embodiment of the present invention provides a method for defrosting the refrigerating compartment of a refrigerator, which is applied to the refrigerator described in the first embodiment. The refrigerator includes a refrigerating compartment, a freezing compartment, a compressor, and an evaporator. One side is attached to the inner bladder of the refrigerating room, and a compensation heater is installed on the other side. Combine Figure 5 As shown, including the following steps:

[0062] 501. Obtain the temperature value TF in the freezer compartment and the temperature value Trf on the surface of the heat exchange plate of the evaporator.

[0063] Combine Figure 1 to Figure 4 In the corresponding embodiment, the refrigerator may measure TF through the first temperature sensor, and measure Trf through the second temperature sensor, and the temperature sensor sends the measured result to the controller of the refrigerator.

[0064] 502. Aft...

Abstract

The embodiment of the invention provides a refrigerator and a defrosting method for a refrigerating chamber of the refrigerator and relates to the field of household appliances. The refrigerator and the defrosting method for the refrigerating chamber of the refrigerator can solve the problem that before a compressor restarts, formed frost cannot be completely molten. According to the specific technical scheme, the defrosting method comprises the steps that the temperature value TF in a freezing chamber and the temperature value Trf of the surface of an evaporator heat exchange plate are obtained; and after the compressor stops, when it is confirmed that TF is larger than T5, a compensating heater is switched on, and when it is confirmed that Trf is larger than T3, the compensating heater is switched off, wherein T5 is the temperature threshold, for controlling the heater to be switched on, of the freezing chamber, T3 is the temperature threshold, for controlling defrosting to be ended, of the surface of the evaporator heat exchange plate, T3 is larger than T4 and smaller than T1, T4 is the temperature threshold, for triggering the compressor to be switched off, of the refrigerating chamber, and T1 is the temperature threshold, for triggering the compressor to be switched on, of the refrigerating chamber. The defrosting method for the refrigerating chamber is used for manufacturing of the refrigerator.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a method for defrosting a refrigerator and a refrigerated compartment thereof. Background technique [0002] The refrigerating system of the refrigerator includes a compressor, a condenser, a capillary tube, an evaporator, an air return pipe, and refrigerant flowing in the above-mentioned refrigerating system pipeline. [0003] When the system is cooling, the compressor is turned on, and the high-temperature and high-pressure gaseous refrigerant discharged from the compressor exhaust port flows into the condenser. After the condenser dissipates heat, the refrigerant is cooled into a medium-temperature and high-pressure liquid refrigerant. A large amount of heat is released during the phase transition of the liquid state. The medium-temperature and high-pressure liquid refrigerant flowing out of the condenser becomes a medium-temperature and low-pressure liquid refrigerant after be...
