Problems solved by technology
[0009] However, in conventional refrigerators, when the defrosting heater is installed only under the evaporator, the defrosting time may increase
In case electric heaters are installed above and below the evaporator to shorten the defrost time, the power consumption may increase
[0010] In addition, when the evaporator is heated and defrosted, the temperature in the refrigerator rises, resulting in a decrease in the cooling effect and cooling efficiency of the refrigerator, which deteriorates the power consumption of the refrigerator

Embodiment Construction
[0033] Please refer to Figure 1-7 As shown, the present invention proposes a defrosting system for a refrigerator evaporator. Such as figure 1 A preferred refrigerator in the embodiment of the present invention includes a refrigerator body 8. The refrigerator storage room 801 in the refrigerator body 8 is composed of a freezer storage room located at the upper side of the refrigerator body 8 and a refrigerated storage room located at the lower side of the refrigerator body 8. , the freezer storage room communicates with the refrigerated storage room through the air duct 802 at the rear side. Such as figure 2 , The refrigerator also includes a compressor unit, and the compressor unit includes a compressor connected in series, a condenser, a dry filter, an evaporator 7, a capillary tube, and an electromagnetic valve.
[0034] A casing 1 is installed in the refrigerator body 8 , and the casing 1 is installed on the rear side of the air duct 802 of the refrigerator storage ro...

The invention discloses a defrosting system for a refrigerator evaporator. According to the defrosting system, a control system comprises a control module, a first temperature detection module and a second temperature detection module, wherein the first temperature detection module and the second temperature detection module are connected with the control module; when the control module receives that the temperature detected by the first temperature detection module reaches a preset threshold t1, the control module controls a driving mechanism to drive a window door to close a window, controls an electromagnetic valve to close the evaporator, and controls a heater to be started to heat the evaporator; when the control module receives that the temperature detected by the second temperature detection module reaches a preset threshold t2, the control module controls the heater to be closed, and the control module controls the electromagnetic valve to open the evaporator; and when the control module receives that the temperature detected by the second temperature detection module reaches a preset threshold t0, the control module controls the driving mechanism to drive the window door to open the window. The defrosting system can reduce power consumption of follow-up work of the refrigerator, and defrosting cannot cause reduction of the cooling efficiency of the refrigerator.
Description
technical field [0001] The invention relates to the technical field of refrigerator defrosting, in particular to a defrosting system for a refrigerator evaporator. Background technique [0002] As is well known, a refrigerator is a device for storing food at a low temperature and keeping the food in a fresh state for a longer period of time. [0003] The refrigerator is provided with a storage compartment for storing food and a refrigeration cycle device for supplying cool air to the storage compartment. [0004] As the refrigeration cycle apparatus, a vapor compression type refrigeration cycle apparatus for compressing, condensing, expanding, and evaporating a refrigerant is generally used. [0005] Once the refrigeration cycle equipment is driven, frost is generated on the surface of the evaporator due to condensation of moisture in the air. [0006] If the amount of frost on the surface of the evaporator increases, heat exchange efficiency between the air and the refrig...
