Problems solved by technology
However, this method of setting the defrosting start point based on experience has poor defrosting effect because the frosting situation cannot be clearly determined.
For example: in some cases, when the cooling preset is reached, the frosting thickness of the evaporator is not high, but the electric heating device starts to work for defrosting, which not only shortens the cooling time of the compressor but also wastes heating energy; in other In some cases, when the frost layer of the evaporator is already very thick and needs to be defrosted, but the program does not allow defrosting because the preset time has not been reached, which will affect the normal operation of the evaporator

Embodiment Construction
[0026] An embodiment of the present invention provides a refrigerator. The refrigerator is an air-cooled refrigerator, which includes: a box body, a door body, an evaporator 200, a compressor, a condenser and other components. A storage compartment and an evaporator compartment communicating with the storage compartment are formed inside the box body, and the evaporator compartment is formed at the rear of the storage compartment. The evaporator chamber extends along the vertical direction of the refrigerator, and the evaporator 200 is disposed in the evaporator chamber and provides cooling capacity to the storage compartment. Such as figure 1 As shown, the box body further includes: a refrigerator shell, an inner tank 102 , an air duct bottom plate 104 , and an air duct cover plate 103 and other components. The liner 102 is arranged on the inner layer of the shell, and the interior of the liner 102 forms a storage compartment, an evaporator room and an air supply duct. The...

The invention provides a refrigerator. The refrigerator comprises a refrigerator body, an evaporator, elastic devices and tension sensors, wherein one end of each elastic device is connected with thesurface of the evaporator, and the other end of each elastic device is directly or indirectly connected with the inner wall of an evaporator chamber, so that the evaporator can be hung in the interiorof the evaporator chamber; each tension sensor is connected with at least one elastic device in series, and the tension sensors are configured to determine the frosting degree of the surface of the evaporator by detecting the tension values of the elastic devices; according to the refrigerator, the tension sensors are used by the refrigerator according to the characteristic that the weight of theevaporator increases along with the improving of frosting degree for detecting the tension values of the elastic devices to judge the frosting degree of the surface of the evaporator; the refrigerator has more accurate judgment on the frosting degree of the evaporator, the time length and the starting time point of the subsequent defrosting process can be accurately determined, so that the defrosting effect of the evaporator is improved.
Description
technical field [0001] The invention relates to refrigeration equipment, in particular to a refrigerator. Background technique [0002] After the air-cooled refrigerator or some other refrigerating equipment has been in operation for a period of time, the evaporator will have frosting, which will affect the heat dissipation of the evaporator, thereby affecting the operating efficiency of the refrigerator. Therefore, refrigerators or other refrigeration equipment need to defrost the evaporator after cooling for a period of time, and generally use an electric heating device to defrost the evaporator. [0003] However, the current defrosting method used by refrigerators or refrigeration equipment is to set a preset time according to empirical data, and automatically start defrosting after the refrigerator or refrigeration equipment runs for a preset time. However, this method of setting the defrosting start point based on experience has poor defrosting effect because the frost...
