Description

Air duct component and refrigerator Technical Field The utility model relates to the technical field of refrigerators, in particular to an air duct component and a refrigerator. Background The refrigerating air duct of the side-by-side combination refrigerator generally comprises an air inlet and a plurality of air outlets corresponding to the refrigerating chambers one by one, and because the number of the air outlets is large and the air quantity requirements of the refrigerating chambers are different, the refrigerating air duct generally comprises at least two air outlet air ducts communicated with an air supply air duct, and each air outlet air duct is provided with at least one air outlet. However, due to the design that the air quantity in one air supply duct is split by each air outlet duct, the air quantity in some air outlet ducts is too small, and then airflow separation is caused to form vortex, so that the refrigerating effect of the refrigerator is affected.
