However, the defrosting scheme in the prior art mainly designs the duration of the defrosting cycle in combination with the running time of the refrigerator or the number of times the door is opened. Defrost cycle, so that when the defrost cycle is short, the defrost operation is frequent, the reliability of the refrigerator is improved, and the possibility of frost blocking the air duct is reduced, but the power consumption of the user is too much; and the defrost cycle is longer For a long time, the number of defrosting operations is relatively small, and the energy consumption of the user's home is reduced, but the reliability of the refrigerator is reduced

Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] The refrigerator defrosting control method and the refrigerator defrosting control device provided by the embodiments of the present invention are applied to air-cooled refrigerators using inverter compressors. Usually, the frosting of air-cooled refrigerators is mainly due to moisture in the air brought in by opening the door or The moisture brought in by the placed items is caused by condensation, so the more times the door is opened, the more likely i...

The embodiment of the invention discloses a refrigerator defrosting control method, a refrigerator defrosting control device and a refrigerator, relates to the field of household appliances, and provides a novel defrosting scheme by which the energy consumption is reduced while the defrosting performance is guaranteed. The refrigerator defrosting control method comprises the following steps: acquiring the opening times of the refrigerator within a predetermined time period, and acquiring the time duration of an overclocking operation of an inverter compressor during each opening; according tothe opening times and the time duration of the overclocking operation of the inverter compressor during each opening, calculating the total time duration of the overclocking operation of the invertercompressor within the predetermined time period; according to the opening times and the total time duration, querying a mapping table to acquire the time duration of a defrosting cycle, wherein the mapping table includes mapping relationships between the opening times and the time duration of the defrosting cycle and between the total time duration and the time duration of the defrosting cycle; the time duration of the defrosting cycle increases along with decrease in the opening times and increases along with decrease in the total time duration.
Description
technical field [0001] Embodiments of the present invention relate to the field of household appliances, and in particular to a method and device for controlling defrosting of a refrigerator and the refrigerator. Background technique [0002] At present, air-cooled refrigerators usually use a finned evaporator, and after a period of operation, the frosting of the evaporator will seriously affect the cooling and heat exchange effect of the evaporator. Therefore, it is usually necessary to design the defrosting function. However, the defrosting scheme in the prior art mainly designs the duration of the defrosting cycle in combination with the running time of the refrigerator or the number of times the door is opened. Defrost cycle, so that when the defrost cycle is short, the defrost operation is frequent, the reliability of the refrigerator is improved, and the possibility of frost blocking the air duct is reduced, but the power consumption of the user is too much; and the d...
