Description

Air duct cover plate and refrigerator Technical Field The disclosure relates to the technical field of refrigerators, in particular to an air duct cover plate and a refrigerator. Background In the related art, a refrigerator is provided with an air duct cover plate, and after a fan blows cold air into an air duct in the air duct cover plate, the cold air is blown into a storage chamber of the refrigerator through an air outlet of the air duct. At present, the uniformity of air outlet is relatively poor, which results in relatively poor air outlet effect of the air duct cover plate. Disclosure of utility model The purpose of this disclosure is to provide an air duct apron, and the air-out effect of this air duct apron is better. In order to achieve the above-mentioned purpose, the present disclosure provides an air duct cover plate, the air duct cover plate is provided with the air outlet, air outlet department is provided with wind guiding structure, the air outlet has the central line that extends along self air-out direction, wind guiding structure includes at least one wind-guiding face, wind-guiding face slope sets up, and self downstream end is close to in self upstream end compare the central line. Optionally, the at least one air guiding surface comprises a first air guiding surface, the air duct cover plate comprises a first side wall and a second side wall which are oppositely arranged, the first side wall and the second side wall are used for enclosing the air outlet, and at least one of the first side wall and the second side wall is provided with the first air guiding surface.
