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

Embodiment 1

[0045] Such as Figure 1 to Figure 11 , a constant temperature fresh-keeping device, including a refrigerated liner 1, a fruit and vegetable box shelf assembly 2 is arranged in the refrigerated liner, and a fresh-keeping compartment is located below the fruit and vegetable box shelf assembly.

[0046] The fresh-keeping compartment includes a drawer assembly 3 and an air duct cover plate 4 , the air duct cover plate 4 is fixed on the inner rear side wall of the refrigerator liner 1 , and a thermostatic adjustment assembly 5 is arranged above the drawer assembly 3 .

[0047] The thermostatic adjustment assembly includes a cold storage material support 6, a cold storage material 7 is arranged in the cold storage material support, and an upper cover 8 is also arranged on the cold storage material support. The thermostatic adjustment assembly can perform constant temperature adjustment on the inner cavity of the drawer assembly.

[0048] Fresh-keeping compartment also comprises lef...

Embodiment 2

[0067] The principle of embodiment 2 is the same as that of embodiment 1. In terms of structure, only the thermostatic adjustment assembly and the fruit and vegetable box shelf assembly are integrated, and the left bracket and the right bracket are replaced by an integrated base.

[0068] to combine Figure 12 to Figure 16 , the constant temperature adjustment assembly is installed in the fruit and vegetable box shelf assembly, the cold storage material support 31 is installed at the bottom of the fruit and vegetable box shelf assembly, and a temperature sensor 32 is arranged in the cold storage material support, and the temperature sensor 32 is used to detect the indoor temperature value of the fresh-keeping room, and Feedback the detected temperature value to the control system.

[0069] A shelf glass 33 is installed on the cold storage material support, an adjustment panel 34 is arranged on the front of the shelf glass, and a temperature adjustment button is arranged on the...

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. ...
