Constant temperature fresh-keeping device

Abstract

The invention provides a constant temperature fresh-keeping device comprising a cold storage liner. The cold storage liner is internally provided with a fruit and vegetable box shelf component, and afresh-keeping chamber is arranged below the fruit and vegetable box shelf component, and comprises an air duct cover plate and a drawer component; the air duct cover plate is fixed to the inner rear side wall of the cold storage liner, and a thermostatic control component is arranged above the drawer component, and comprises a cold storage material holder which is internally provided with cold storage materials; and an inner cavity of the drawer component can be subjected to thermostatic control through the thermostatic control component. According to the constant temperature fresh-keeping device provided by the invention, through the circulation process that the cold storage materials absorb and release cold continuously, the temperature fluctuation of the fresh-keeping chamber is reduced, and the fresh-keeping effect is improved; the water loss of food is reduced while the temperature fluctuation of the fresh-keeping chamber is reduced; and the food freshness is maintained. The constant temperature fresh-keeping device provided by the invention is simple in structure and easy to install, and the cold storage materials are easy to replace, and has no disturbance to airflow in thefresh-keeping chamber of an air-cooled refrigerator.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a constant temperature preservation device applied to an air-cooled refrigerator. Background technique [0002] At present, refrigerators and freezers on the market can be divided into direct cooling type and air-cooled type according to the refrigeration principle. Air-cooled refrigerators and freezers can be cooled by air supply through air ducts according to the cooling demand of each space. Due to the remarkable advantages of fast cooling speed and no frosting of the inner container, the air-cooled refrigerator-freezer is more and more popular among families. [0003] The air-cooled refrigerator cools the fresh-keeping room by sending cold air through the fan. When the fan is working, the cold air enters the fresh-keeping room, and the temperature of the fresh-keeping room drops rapidly. When the fan stops working, the cold air no longer enters the fresh-keeping room. ...

AI Technical Summary

Problems solved by technology

[0003] The air-cooled refrigerator cools the fresh-keeping room by sending cold air through the fan. When the fan is working, the cold air enters the fresh-keeping room, and the temperature of the fresh-keeping room drops rapidly. When the fan stops working, the cold air no longer enters the fresh-keeping room. The temperature rises and repeats like this, resulting in large temperature fluctuations in the refrigerator and fresh-keeping room, and large temperature fluctuations are very unfavorable to the fresh-keeping storage of food

And temperature fluctuations will make the water in the food cells evaporate continuously, making the food in the fresh-keeping room dry and affecting the fresh-keeping effect

[0004] In view of the above problems, the existing technology is to apply cold storage materials around the inner tank, or add cold storage materials in the air duct, etc. Although the temperature fluctuation in the storage space can be reduced, it is still difficult to apply the cold storage materials and it is inconvenient to install. Or have defects such as additional airflow disturbances
