Freezing thermostatic chamber, air-cooled refrigerator and temperature control method of air-cooled refrigerator

Abstract

The invention provides a freezing thermostatic chamber, an air-cooled refrigerator and a temperature control method of the air-cooled refrigerator. The freezing thermostatic chamber comprises an inner container which forms a storage cavity, a casing arranged on the outer side of the inner container and a cold storage material arranged between the inner container and the casing and attached to the inner container; cooling air channels are formed between the inner container and the casing and between the cold storage material and the casing; an air inlet and an air outlet which communicate with the cooling air channels are formed in the casing; a quick-cooling air inlet is formed in the side, facing the air inlet, of the inner container; and an air door is arranged at the quick-cooling air inlet. With the freezing thermostatic chamber and the air-cooled refrigerator, quick cooling inside the freezing thermostatic chamber is realized, the temperature fluctuation is reduced, the loss of nutrients of food is reduced, and the taste and the freshness of the food are kept.

Description

Technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a freezing constant temperature chamber capable of effectively reducing temperature fluctuations, an air-cooled refrigerator with the freezing constant temperature chamber and a temperature control method thereof. Background technique [0002] Air-cooled refrigerators can effectively avoid frosting on the inner liner, and are more and more popular with modern families. At present, the temperature fluctuation in the box of the general air-cooled refrigerator is about ±1K during the stable operation stage, and the temperature fluctuation in the box will increase during the defrosting stage of the evaporator, especially the temperature fluctuation in the freezer compartment may even rise to 5K. The increase in temperature causes the relative humidity in the freezer compartment to decrease, which in turn causes the water in the food to evaporate; when the temperature decreases, the ...

AI Technical Summary

Problems solved by technology

The industry has also proposed a solution to reduce temperature fluctuations in the box by installing a cold storage device, but there are still problems such as uneven cooling of the cold storage device

[0004] On the other hand, in the process of traditional food frozen storage, the cooling speed is slow, and the food cells are severely damaged, which affects the taste of food

Chinese patent CN104121742 A discloses a refrigerator with a quick-freezing compartment, but it does not completely solve the problems of rapid cooling of the quick-freezing compartment and temperature stability of the quick-freezing compartment
