TECHNICAL FIELD

[0001] The present application relates to the field of refrigeration equipment, in particular to a refrigerator. BACKGROUND

[0002] The refrigerator air duct is mainly composed of an air duct cover plate, an air duct foam and a PE film. Generally, the air duct cover plate is made of PS material with high hardness to reduce deformation caused by stress and avoid separation of the air duct cover plate and the air duct foam.

[0003] However, the PS material is high in cost. If the PS material is directly replaced by PP material, the PP material is soft and is prone to separation after assembly with the air duct foam and the inner container, resulting in an assembly failure. Therefore, it is necessary to provide an improved refrigerator to solve the above problems. SUMMARY

[0004] To solve the above technical problems, the present application provides a refrigerator.

[0005] To achieve the above purpose, the technical scheme provided by the present application is as follows: a refrigerator comprising an inner container surrounding a refrigeration chamber and an air duct assembly fixed to the rear wall of the inner container, the air duct assembly comprising an air duct foam and an air duct cover plate covering the air duct foam, the material of the air duct cover plate being PP, the air duct cover plate being provided with a plurality of buckles, each buckle comprising a base, a buckle portion extending outward from the base, and a reinforcing rib fixed to at least one of the base and the buckle portion, the inner container being provided with a fixing portion corresponding to each buckle.

[0006] As a further improvement of the present application, reinforcing ribs are arranged on the base and the buckle portion.

[0007] As a further improvement of the present application, the reinforcing ribs are arranged along the direction of the base towards the buckle portion.

[0008] As a further improvement of the present application, two long reinforcing ribs and two short reinforcing ribs arranged on both sides are arranged on the base of each buckle.

[0009] As a further improvement of the present application, in the direction perpendicular to the direction of the base towards the buckle portion, the distance between the two long reinforcing ribs on each base is not greater than the width of the buckle portion, and the distance between the two short reinforcing ribs on each base is greater than the width of the buckle portion.

[0010] As a further improvement of the present application, part of the buckles comprise a clamping port, the clamping port being arranged on the base to clamp the air duct foam.

[0011] As a further improvement of the present application, the buckle of the card interface is arranged on the upper side of the air duct cover plate.

[0012] As a further improvement of the present application, the air duct assembly further comprises a screw for fixedly connecting the air duct cover plate and the air duct foam.

[0013] As a further improvement of the present application, the fixed part is recessed from the inner side of the inner container.

[0014] The refrigerator of the present application changes the air duct cover plate into PP material, which greatly reduces the cost of the air duct cover plate while ensuring the appearance and function unchanged, and is simple to assemble and disassemble. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in conjunction with specific embodiments of the present application and corresponding drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0023] As shown in Figures 1 to 5 The present application proposes a refrigerator 100, which comprises an inner container 1 surrounding a refrigeration compartment and a duct assembly 2 fixed to the rear wall of the inner container 1. The duct assembly 2 comprises a duct foam 21 and a duct cover plate 22 covering the duct foam 21, and the duct cover plate 22 is assembled with the duct foam 21 and then fixedly connected with the inner container 1 to complete the installation of the refrigerator duct.

[0024] The material of the duct cover plate 22 is PP, which greatly reduces the cost of the duct cover plate 22 while ensuring the appearance and function unchanged, and the assembly is simple and can be disassembled; a plurality of buckles 221 are provided on the duct cover plate 22, the buckle 221 comprises a base 2211, a buckle portion 2212 extending outward from the base 2211, and a reinforcing rib 2213 fixed to at least one of the base 2211 and the buckle portion 2212, so that the hardness of the buckle 221 reaches the effect of a conventional buckle 221 and is not easy to deform under stress, thereby the duct cover plate 22 is firmly clamped with the inner container 1.

[0025] As shown in Figure 4 and Figure 5 The reinforcing ribs 2213 are provided on the base 2211 and the buckle portion 2212 to enhance the hardness of the buckle 221; specifically, the reinforcing ribs 2213 are provided in the direction of the base 2211 towards the buckle portion 2212, two long reinforcing ribs 2213 and two short reinforcing ribs 2213 arranged on both sides are provided on the base 2211 of each buckle 221, the distance between the two long reinforcing ribs 2213 on each base 2211 in the direction perpendicular to the direction of the base 2211 towards the buckle portion 2212 is not greater than the width of the buckle portion 2212, and the distance between the two short reinforcing ribs 2213 on each base 2211 is greater than the width of the buckle portion 2212.

[0026] The duct assembly 2 further comprises a screw 23, and a plurality of screw holes corresponding to the screw 23 are provided on the duct foam 21 to fix the duct cover plate 22 and the duct foam 21 by the screw 23.

[0027] Further, as shown in Figure 4As shown, part of the buckle 221 comprises a clamping interface 2214 which is provided on the base 2211 to clamp the air duct foam 21; in particular, the buckle 221 provided with the clamping interface 2214 is arranged on the upper side of the air duct cover plate 22, and the air duct foam 21 is foamed and filled into the clamping interface 2214, so as to fix the air duct cover plate 22 and the air duct foam 21.

[0028] The air duct cover plate 22 and the air duct foam 21 are mainly connected through the screw 23, and the buckle 221 provided with the clamping interface 2214 is additionally used to fix the air duct foam 21.

[0029] As shown in the drawings, Figure 2 As shown, the inner container 1 is provided with a fixing portion 11 which is matched with the buckle 221, and when the air duct cover plate 22 is clamped with the inner container 1, the clamping portion 2212 is clamped with the fixing portion 11.

[0030] In particular, the fixing portion 11 is concave from the inner side of the inner container 1 to the outside, and here the side of the inner container 1 facing the refrigeration compartment is the inner side.

[0031] Therefore, as described above, the refrigerator 100 changes the air duct cover plate 22 into PP material, which greatly reduces the cost of the air duct cover plate 22 while ensuring the unchanged appearance and function, and is simple to assemble and can be disassembled; the buckle 221 provided with the reinforcing rib 2213 is used to fix the air duct cover plate 22 and the inner container 1; and the screw 23 and the buckle 221 provided with the clamping interface 2214 are used to fix the air duct cover plate 22 and the air duct foam 21.

[0032] The above only describes the preferred embodiments of the present application, and it should be noted that for those skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application.
