Embodiment 1

[0031] See figure 2 The condensed air circulation rear cover 1 of the first embodiment includes an air inlet 102 on the air inlet side and an air outlet 101 on the air outlet side.

[0032] See image 3 , the air outlet 101 is obtained by punching and flanging, and the edge of the flanging part 103 forms the splitter tooth 104, the tooth shape of the splitter tooth 104, please refer to Figure 4 . It should be noted that the tooth shape of the shunt teeth 104 is not limited by the drawings, and it may also be triangular teeth, rectangular teeth, and crescent shapes.

[0033] In the first embodiment, by setting a split flow structure at the air outlet 101 , it is possible to avoid the problem of poor air circulation caused by turbulence at the air outlet side, thereby effectively improving the heat exchange efficiency of the condenser 4 .

[0034] See Figure 5 In order to further improve the condensation efficiency of the condenser 4, the air inlet 102 of the condensed ai...

Embodiment 2

[0040] The difference between the second embodiment and the first embodiment lies in the structure of the air outlet side, therefore, the second embodiment only describes the structure of the air outlet side. As for the same structure as that of the first embodiment, it will not be repeated here.

[0041] The air outlet 101 of the second embodiment is obtained by punching and flanging, and the flanging portion 103 is formed with flow-distributing ribs extending along the air outlet direction, so that the air outlet 101 is separated by the flow-distributing ribs to form multiple channels. Among them, the formation of multiple channels can avoid the occurrence of disturbances.

[0042] Further, it is preferable that the size of the splitter rib increases gradually along the direction of the air outlet, so that the cross-sectional size of the air flow channel gradually decreases along the direction of the air outlet, thereby better avoiding the occurrence of turbulent flow.

Embodiment 3

[0044] The difference between the third embodiment and the first embodiment lies in the structure of the air outlet side, therefore, the third embodiment only describes the structure of the air outlet side. As for the same structure as that of the first embodiment, it will not be repeated here.

[0045] See Figure 7 In the third embodiment, the flow distribution structure is the flow distribution teeth 104 formed on the edge of the air outlet 101 . The tooth shape of the shunt teeth 104 is also not limited here.

[0046] In the third embodiment, the splitter tooth 104 is directly arranged on the air outlet 101, and the obtained air outlet 101 has a simple structure and is easy to process, which is beneficial to reduce production costs. Of course, the setting of the splitter tooth 104 at the air outlet 101 is not limited by the drawings, and it can also be arranged at the upper edge of the air outlet 101 or at the left and right edge positions of the air outlet 101 according...

Abstract

The invention relates to the technical field of household appliances, and provides a condensation air circulation rear cover plate, a condensation air duct system and a refrigerator. The condensation air circulation rear cover plate comprises an air inlet located in the air inlet side and an air outlet located in the air outlet side. A flow distribution structure is arranged at the air outlet. According to the scheme, the flow distribution structure is arranged at the air outlet, and therefore the problem of airflow circulation blocking caused by turbulent flow at the air outlet side can be solved, and heat exchange efficiency of a condenser is effectively improved.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a condensing air circulation rear cover, a condensing air duct system and a refrigerator. Background technique [0002] In existing refrigerators, the condensing air duct system mostly uses an axial fan to circulate the condensing air from the air inlet side of the rear cover 1, and discharges it through the air outlet side of the rear cover. For the structure of cover plate 1 after condensing air circulation, please refer to figure 1 . Wherein, air turbulence often exists at the air outlet 101 on the air outlet side, so that the air outlet is not smooth and the condensation efficiency is reduced; and the turbulence will generate relatively large noise. In addition, the fan 3 is arranged in the condensing air bin, so that the air flow enters the condensing air bin through the air inlet 102 , and passes through the condenser 4 for heat exchange before passing through the...
