Air-cooled refrigerator

Abstract

The invention provides an air-cooled refrigerator. The air-cooled refrigerator is characterized in that the air-cooled refrigerator comprises a freezing chamber, a refrigerating chamber, an evaporator, a refrigerating chamber refrigerating device and a freezing chamber air current circulation device, wherein the freezing chamber is used for freezing foods, the refrigerating chamber is fixed above the freezing chamber and used for refrigerating foods, the evaporator is arranged on the rear side of the freezing chamber to enable air to release heat to form cold air, the refrigerating chamber refrigerating device is arranged below the refrigerating chamber and used for refrigerating the refrigerating chamber, and the freezing chamber air current circulation device is arranged on the rear wall of the freezing chamber and used for blowing the cold air to the freezing chamber to promote air current circulation of the freezing chamber, wherein the refrigerating chamber refrigerating device comprises a body, fins, a refrigerating chamber fan and a refrigerating chamber cold accumulation layer, the freezing chamber air current circulation device comprises a body, a freezing chamber fan, an air inlet and a freezing chamber cold accumulation layer, the refrigerating chamber cold accumulation layer and the freezing chamber cold accumulation layer are both made of phase change cold accumulation materials, the phase change cold accumulation materials can absorb the refrigerating capacity of the cold air and eliminate temperature rise caused by defrosting when the refrigerating chamber and the freezing chamber are defrosted.

Description

technical field [0001] The invention relates to an air-cooled refrigerator for household appliances, in particular to an air-cooled refrigerator in which the air in the freezing chamber and the refrigerating chamber are independently circulated and a phase-change cold storage material is used to reduce the effect of defrosting and temperature rise. Background technique [0002] Along with the raising of people's living standard, household electric refrigerator becomes every household necessity more and more. In recent years, the development of refrigerators has been very rapid, especially air-cooled refrigerators are more popular with the public, not only because they have faster cooling speed and more uniform temperature distribution than direct-cooled refrigerators, but also because air-cooled refrigerators are without Frost refrigerator. [0003] The principle of the air-cooled refrigerator is that high-temperature air flows through the built-in evaporator for heat excha...

AI Technical Summary

Problems solved by technology

Although these measures have achieved certain effects, they still have not completely solved the above-mentioned defects.

At the same time, equipment such as humidifiers complicate the structure of the refrigerator and increase the cost. Return air defrosting humidification and optimizing the defrosting program have not fundamentally reduced the amount of frosting on the evaporator, and still need to consume more power to defrost.
