Door pipeline assembly of refrigerator

Abstract

The invention relates to a gate pipe component of a fridge, comprising a cold gas connecting part, a flow guide device, wherein the cold gas connecting part is detachable arranged in the door of the storing space used to open or close the fridge body, and a connecting pipe is selectively arranged with the fridge body, the flow guide device and a door lining board composes the flow passage of the cold gas provided by the cold gas connecting part, and the rear face is provided with a flow passage forming rib, the front end of the flow passage forming rib is contacted with the door lining board, to form a flow passage that the flow area is not bigger than the flow area of the connecting pipe. The cold gas connecting part of The invention is detachable arranged at the door, to make the cold gas provided by the pipe provided by the fridge body relatively homogeneously flow inside the flow passage formed at the door, to make the insulation effect between the flow passage parts of the door of the connecting pipe of the fridge body.

Description

technical field [0001] The invention relates to a door duct assembly for a refrigerator. Background technique [0002] Generally speaking, the cold air circulation process in the refrigerator is as follows: when the low-temperature refrigerant passes through the evaporator, the air around the evaporator will exchange heat with the above-mentioned refrigerant passing through the evaporator, and become low-temperature cold air. The above-mentioned cold air that has become low temperature will be supplied to the freezer compartment and the refrigerator compartment respectively to complete the cooling function, and then flow into the evaporator side again, and the above process is repeated. [0003] In the refrigerator as described above, if there are many stored objects in the freezing chamber and the refrigerating chamber, the flow of cold air will not be smooth enough. Therefore, cool air needs to be supplied from multiple directions to the inside of the freezer compartment ...

AI Technical Summary

Problems solved by technology

[0013] In addition, between the above-mentioned support protrusions 17, the flow cross-sectional area of ​​the flow path formed by the above-mentioned door liner 15, the horizontal protrusion 18 and the flow guide device 28 is relatively larger than the flow cross-sectional area of ​​the above-mentioned cold air connecting portion 26, so Severe eddy currents will be generated inside the flow path, and the air cannot be discharged uniformly through the above-mentioned cold air holes 29

[0014] In addition, in existing refrigerators, the above-mentioned supporting protrusions 17 around the cold air connecting portion 26 and the flow guiding device 28 adjacent to the supporting protrusions 17 will cause condensation and other phenomena due to temperature differences.
