Description

Technical Field

[0001] The invention belongs to the technical field of refrigerators, and in particular relates to a refrigerator freezing air duct assembly. Background Art

For refrigerators of different sizes, the sizes of the refrigeration air duct components used are also different. Each component of the refrigeration air duct component needs to be newly designed, which not only increases the design cycle of the product, but also greatly increases the investment in mold costs. Summary of the invention

[0003] The object of the present invention is to provide a refrigerator freezing air duct assembly, aiming to solve the design problem of refrigerator freezing air duct assemblies of the same width but different heights or depths in the prior art.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The present invention discloses a refrigerator freezing air duct assembly, comprising a mask, an air duct and an air duct cover which are sequentially mounted on a refrigerator freezing chamber; the air duct cover is provided with an air supply interface, an air guide ring, an air guide plate, and a screw hole B which matches with an upper stud; the mask is an integral structure comprising an upper mask and a lower mask; the upper mask is provided with an upper air outlet, a sensor mounting slot, a fan mounting slot, an upper clamping claw A and an upper stud; a plurality of mounting clamping claws A are provided on an edge side of the upper mask away from the lower mask, and a plurality of mounting clamping claws are provided on both sides of the upper mask. Claw B, the two opposite edge sides of the upper mask are respectively provided with fixing parts and the fixing parts are provided with screw holes A; the lower mask is provided with a lower air outlet and a return air flow duct connected to the lower air outlet, and the two sides of the lower mask are respectively provided with a lower claw A and a lower claw B; the air duct is an integral structure, which includes an upper air duct and a lower air duct; the upper air duct is provided with an air guide structure, an upper air outlet flow duct, and a return air outlet matched with an air guide ring; the lower air duct is provided with a lower air outlet flow duct and a slot matched with the lower claw B.

[0006] Furthermore, a fan is installed in the fan installation slot.

[0007] Furthermore, a viscose sponge is pasted on the back of the lower air duct of the air duct; and the air duct is an EPS foam part.

[0008] Furthermore, the air supply interface is arranged on the air duct cover above the air guide ring, the air guide plate is arranged on one side of the air supply interface and connected to the air supply interface, and the air duct cover is a plastic part.

[0009] Furthermore, the air supply interface is coordinated and communicated with the air guide structure.

[0010] The present invention has the following beneficial effects:

[0011] The present invention fixes and modularizes the air duct cover, upper mask and upper air duct structure in the freezing air duct assembly. The air duct cover, upper mask and upper air duct structure in the present invention can be used for refrigerators of the same width. Only the length of the lower mask and the lower air duct needs to be changed, thereby shortening the product design cycle and reducing the investment in product mold costs.

[0012] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
