Air-cooled refrigerator

Abstract

The invention provides an air-cooled refrigerator. The air-cooled refrigerator comprises a refrigerator main body, a receiving chamber arranged inside the refrigerator main body and divided by separation layers into a plurality of separated chambers, and an air duct arranged inside the refrigerator main body; air supply openings and air return openings are formed in the air duct at the positions corresponding to every separated chambers; air in the air duct goes into each separated chamber via the air supply opening of each separated chamber, and air in each separated chamber goes back to the air duct via the air return opening of each separated chamber. According to the air-cooled refrigerator, the cooling scheme of the original air-cooled refrigerator is changed, hierarchic refrigeration of the air-cooled refrigerator is realized, and therefore, the cold stored articles in the top of the refrigerator can be prevented from being air-dried and the refrigeration homogeneity and the cold storage effect on the cold stored articles are improved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to an air-cooled refrigerator. Background technique [0002] Such as Figure 1A and Figure 1B As shown, the existing air-cooled refrigerator adopts an integrated cooling scheme for the space inside the box, that is, the cold energy is sent into the entire box space, and the entire box is cooled at one time. The air supply port of the existing air-cooled refrigerator is located at the top of the storage chamber, and the air return port is located at the lower position of the back of the tank. The cold air formed by the air-cooled refrigerator enters the return air port from the air supply port through the entire storage chamber. Under the action of gravity and the negative pressure of the return air outlet, the cold air will quickly sink to the bottom of the box, which will cause the lower part to be too cold and the top temperature to be too high. Therefore, in order to ens...

Problems solved by technology

[0003] However, this design causes the flow field in the box to be uneven, and a large amount of cold air is blown out from the upper air outlet, causing the food and other refrigerated items placed on the upper part of the air-cooled refrigerator to be easily dried. Most of the cold air is sent to the top of the refrigerator first, and then sinks to the bottom of the box through the action of gravity settling. In this technical solution, the settling effect of gravity is difficult to grasp, so the temperature uniformity in the air-cooled refrigerator is not easy to control
