Problems solved by technology

The problems in this invention patent application are: 1. It does not indicate whether mode 2 is to control the defrosting of the evaporator of the refrigerator or the air duct of the refrigerator, and the defrosting control steps of these two places are different; 2. When the mode 2 is to control the defrosting of the evaporator, because the evaporator is set inside the freezer, when the frost on the evaporator affects the refrigeration, it will first affect the freezer, and the temperature of the freezer is set above zero, which is often not easily affected , or the impact is relatively lagging, so it is difficult to know whether the evaporator is affected by frost when the temperature of the refrigerator is detected; Secondary controls, still flawed

Embodiment 1

[0029] The defrosting control method of the air-cooled refrigerator described in this embodiment includes a conventional control method and an auxiliary control method, wherein the conventional control method is some commonly used control methods at present, and one of the conventional control methods is briefly listed here, such as: detecting the evaporator When the temperature of the evaporator reaches the set value, the defrosting timing program is started, and when the timing time is up, the defrosting program is started. The auxiliary control method cooperates with the conventional control method to further improve the defrosting function, and solves some technical problems in the conventional control method. The auxiliary control method is specifically: figure 1 As shown, firstly, judge whether the door of the refrigerator is closed, because the factors affecting the temperature in the refrigerator are different when the door of the refrigerator is opened or closed. When...

Embodiment 2

[0032]Compared with Embodiment 1, this embodiment is different in that, in the air duct defrosting method of the refrigerator compartment, the temperature continues to rise for 3 minutes; in the defrosting method of the freezer evaporator, if the freezer door is closed, whether the temperature If it reaches -16°C, if it does not reach -16°C, the freezer temperature monitoring program will not be started, if it reaches -16°C, the freezer temperature monitoring program will be started, and it will be judged whether the freezer temperature has risen, if not, it will not be started Evaporator defrosting program, if it rises, judge whether it continues to rise to -12°C, if it does not continue to rise to -12°C, do not start the evaporator defrosting program, if it continues to rise to -12°C, start evaporator defrosting Cream program.

Embodiment 3

[0034] Compared with Embodiments 1 and 2, this embodiment differs in that in the method of defrosting the air duct in the refrigerator, the temperature continues to rise for 5 minutes; in the method of defrosting the evaporator in the freezer, if the door of the freezer is closed, the Whether the temperature reaches -14°C, if it does not reach -14°C, do not start the freezer temperature monitoring program, if it reaches -14°C, start the freezer temperature monitoring program, and judge whether the freezer temperature has risen, if not, then Do not start the evaporator defrosting program, if it rises, judge whether it continues to rise to -11°C, if it does not continue to rise to -11°C, do not start the evaporator defrosting program, if it continues to rise to -11°C, start evaporation defrost program.

[0035] Temperature sensors are respectively installed in the above-mentioned refrigerating chamber and freezing chamber to monitor the temperature, and defrosting devices are in...

Abstract

The invention discloses an air cooling refrigerator defrosting control method. The air cooling refrigerator defrosting control method comprises a conventional control method and an auxiliary control method. The auxiliary control method includes the steps that firstly, whether a door of a refrigerating chamber is closed or not is judged, if the door is not closed, a refrigerating chamber temperature monitoring program is initialized, and if the door is closed, whether a refrigerator begins to refrigerate the refrigerating chamber or not is judged; secondly, if the refrigerator does not begin to refrigerate the refrigerating chamber, the refrigerating chamber temperature monitoring program is not started, and if the refrigerator begins to refrigerate the refrigerating chamber, the refrigerating chamber temperature monitoring program is started, and whether temperature rises or not is judged; thirdly, if the temperature does not rise, a refrigerating chamber air duct defrosting program is not started, and if the temperature rises, whether the temperature continues to rise for more than two minutes or not is judged; fourthly, if the temperature rises for less than two minutes, the refrigerating chamber air duct defrosting program is not started, and if the temperature continues to rise for more than two minutes, the refrigerating chamber air duct defrosting program is started; fifthly, after the refrigerating chamber air duct defrosting program is finished, the refrigerating chamber temperature monitoring program is initialized, and monitoring is conducted again. According to the scheme, the temperature of the refrigerating chamber is monitored, and the air cooling refrigerator defrosting control method is mainly used for avoiding severe frosting of an air duct of the refrigerating chamber.

Description

[0001] technical field [0002] The invention relates to the field of refrigerators, in particular to a defrosting control method for an air-cooled refrigerator. Background technique [0003] The air-cooled refrigerator provides cold air for the refrigerator compartment through the evaporator and the air duct. Because the evaporator contains moisture, frost is easy to occur on the surface of the evaporator and the air duct in the cold storage room at a lower temperature, and the evaporator is located in the freezing room, so when it When the frost is serious, it will directly affect the cooling effect of the freezer; for the air duct of the refrigerator room, it realizes the circulation of cold air from the evaporator to the refrigerator room, and when the frost inside it blocks the air duct, it will affect the cooling effect of the freezer. Therefore, the air-cooled refrigerator needs to defrost the evaporator and the air duct of the cold room regularly. [0004] At presen...
