Refrigerator and quick-freezing method thereof

Abstract

The invention provides a refrigerator and a quick-freezing method thereof. The refrigerator comprises a quick-freezing chamber arranged in a freezing chamber and a variable-temperature chamber arranged in a refrigerating chamber; a single refrigerating system is arranged in the freezing chamber, and the single refrigerating system comprises a first air duct communicating with the freezing chamber,a second air duct communicating with the variable-temperature chamber and a third air duct communicating with the quick-freezing chamber; fans and an air door assembly are arranged among the first air duct, the second air duct and the third air duct, and the air door assembly is used for controlling air inlets of the first air duct, the second air duct and the third air duct to be opened and closed; the first air duct is connected with the air inlet of the refrigerating chamber, and an air door of the refrigerating chamber is arranged at the air inlet of the refrigerating chamber; and the quick-freezing method comprises the step that opening and closing of air inlets of the first air duct, the second air duct and the third air duct are adjusted by controlling the air door assembly. According to the refrigerator and the quick-freezing method thereof, configuration requirements of four temperature zones of freezing, cold storage, quick freezing and temperature changing are met through the single refrigerating system, and the refrigerator has the advantages of being small in occupied size, stable in performance and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a refrigerator and a quick-freezing method for the refrigerator. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for food preservation, especially the food stored in the freezer compartment, which sometimes needs to be frozen quickly to prevent damage to the food cell wall due to too slow freezing speed. In the prior art, a refrigerator with a quick-freezing function is often provided with a quick-freezing compartment, and such a refrigerator includes a first fan, a second fan, an evaporator, a first air duct, and a second air duct. Wherein, the first air duct communicates with the freezing compartment, and the second air duct communicates with the quick-freezing compartment. In general cooling conditions, if the freezer compartment of the refrigerator needs to be refrigerated, the first fan wor...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of the above-mentioned refrigeration system is that at least two fans and their corresponding air doors, air ducts, etc. need to be provided, especially when it is applied in a multi-chamber refrigerator with a variable room, not only the structure is complicated, but the manufacturing cost is high. problems, and will directly affect the effect of quick freezing

[0004] Some refrigerators realize temperature control through a damper or mother-to-child damper, but this kind of damper is generally placed in the cold storage room, which cannot meet the requirements of temperature division in the freezing room, and cannot meet the temperature control of more than two refrigerators.
