Air duct cover plate for air-cooled refrigerator and air-cooled refrigerator with same

Abstract

The invention discloses an air duct cover plate for an air-cooled refrigerator and the air-cooled refrigerator with the same. The air duct cover plate comprises a front cover plate body, a rear coverplate body and an upper cover plate body, wherein the front cover plate body and the rear cover plate body are oppositely arranged, and the upper cover plate body is arranged at the upper ends of thefront cover plate body and the rear cover plate body; the front cover plate body is of a closed structure, and an upper air outlet is formed in the upper cover plate body; a plurality of transverse air guide ribs arranged in the transverse direction are arranged in the upper air outlet in parallel, and the transverse air guide ribs incline forwards by one angle in the vertical direction; and a fangroove and a plurality of air guide plates are arranged on one face, facing the front cover plate body, of the rear cover plate body, the air guide plates are distributed between the fan groove and the upper end face of the rear cover plate body, one ends of the air guide plates face the fan groove, and the other ends of the air guide plates face the upper air outlet. The air outlet is formed inthe upper cover plate body of the air duct cover plate, longitudinal air guide ribs and the transverse air guide ribs arranged in the air outlet and the air guide plates arranged on the rear cover plate body are matched, then one continuous air duct can be formed in the air duct cover plate, and cold air is blown out from the air outlet of the upper cover plate body to the front upper portion so that the cold air can be simultaneously blown to a refrigerator door body and the inner space of a refrigerator box body.

Description

technical field [0001] The invention relates to the field of refrigeration devices, in particular to an air-cooled refrigerator air duct cover plate and an air-cooled refrigerator equipped with the same. Background technique [0002] The air-cooled refrigeration device uses circulating cold air for refrigeration. Compared with the traditional direct-cooled refrigeration device, it has the advantages of no frost, fast cooling speed, and uniform temperature. In the horizontal air-cooled freezer, the air duct is an important refrigerant transfer path, which has a great influence on the cooling effect of the product. [0003] At present, the common air ducts of horizontal air-cooled refrigerators include side wall air ducts and door body air ducts. The side wall air duct is a built-in sealed air duct on the side wall of the freezer. The cold air is blown into the side wall of the box through the side air outlet of the air duct cover, and then blown into the box from the side th...

Problems solved by technology

[0004] However, to cooperate with the current air duct in the door body or the similar upper air duct cover plate, a part of the air duct cover plate is directly provided with a vertical hole-type air outlet, which is airtightly connected with the air inlet of the door body. , the air duct cover plate with this structure has a small and uneven air output, high manufacturing precision requirements, and a large amount of cold air directly collides with the air intake duct of the door body, resulting in kinetic energy loss, high energy consumption and poor cooling effect; the other part A main air outlet is set at the front end of the air duct cover, and a secondary air outlet is arranged above. The internal air duct structure of the air duct cover with this structure is complicated, and the direction of the main air outlet is different from the direction of the wind flow generated by the fan. It will cause kinetic energy loss after the collision of a large amount of flowing cold air
