It includes horizontal plate base 41211 extending along left and right sides, a pair of L-shaped supporting angle parts 41212 bending inwards from the front and back side edge parts of the horizontal plate base 41211. As shown in fig. 4, the two first plate members 4121 are also placed side by side in the front-rear direction. In this example, each of the plurality of first plate members 4121 is mounted in a non-connected manner, and is directly supported on the inner wall surface of the horizontal section 161 by a pair of L-shaped supporting angle portions 41212, two adjacent L-shaped supporting angle portions 41212 are arranged, the foremost L-shaped supporting angle portion 41212 abuts against the inner wall surface of the front side wall 14, and the rearmost L-shaped supporting angle portion 41212 abuts against the inner wall surface of the rear side wall 15.

As shown in fig. 8, the bent portion 4113 of the bottom end of the left air duct plate 411 extends into the left end of the first plate 4121, and the two abut against each other up and down. The mounting structure of the two first plate bodies 4121 of the embodiment can be conveniently detached by a user, and the user can clean the dirt in the air duct of the section after detaching the first plate bodies 4121.

As shown in fig. 10, the second plate 4122 is an integral sheet metal part, which is "L" shaped. The second plate body 4122 includes a vertical plate base surface 41221 extending in the up-down direction, a horizontal plate base surface 41222 extending in the left-right direction, a pair of L-shaped stay corner portions 41223 formed at front and rear side edges of the vertical plate base surface 41221 and the horizontal plate base surface 41222, respectively, and a bent portion 41224 bent to the left from a lower end edge of the vertical plate base surface 41221.

In this example, the support member 62 is disposed between the horizontal plate base surface 41222 and the horizontal step surface 1622 of the second plate member 4122. As shown in fig. 12, the support 62 extends in the left-right direction, and includes a bottom base 621, a pair of vertical portions 622 extending upward along both side edges of the bottom base 621, and a pair of side wing portions 623 each extending outward from a tip end portion of the pair of vertical portions 622. .

As shown in fig. 11, the bottom base 621 of the support member 62 is fixedly coupled to the horizontal stepped surface 1622 by the threaded fastener 52, and the second plate 4122 is supported on the support member 62 by a pair of L-shaped supporting corners 41223.

The lower portion of the bent portion 4133 is further provided with a pair of support legs 4136, and the entire right wind path plate 413 is fixedly attached to the inner wall surface of the stage 162 (here, the boundary between the stage 162 and the right side wall 13) by a screw fastener fixed to the support legs 4136. After the right air duct plate 413 is mounted, the outer end of the bent portion 4132 abuts against the inner wall surface of the right side wall 13, and the pair of folded edges 4135 are closely attached to the inner wall surfaces of the front side wall 14 and the rear side wall 15; the folds 4132 define the width of the air chute 415 at the right side segment.

As shown in fig. 15, the bent portion 4133 of the right air duct plate 413 extends to the lower side of the horizontal plate base surface 41222 and the two are attached together, which can enhance the sealing between the second plate 4122 and the right air duct plate 413, and can effectively reduce the amount of cold air directly escaping into the right air duct plate 413 from the gap at the overlapping position of the bent portion 4133 of the right air duct plate 413 and the right end of the horizontal plate base surface 41222 after the cold air output from the air supply opening 4134 directly falls down, thereby extending the flowing range of the cold air flowing out from the air supply opening 4134 in the refrigeration chamber and improving the refrigeration efficiency. In order to enhance the sealing property at the joint between the second plate 4122 and the right end of the second plate 4122, a seal may be provided at the joint between the bent portion 4133 of the right air duct plate 413 and the right end of the horizontal plate base surface 41222, and the seal may be a flexible gasket, a flexible filler, or the like.

Wherein the compressor assembly 31 and the condenser assembly 32 are mounted outside the foaming cabinet 1 and below the bottom wall stage 162. The evaporator assembly 33 is fixedly mounted on the inner wall surface of the right side wall 13 by a screw fastener and is located inside the air duct 415. The fan assembly 42 is also mounted on top of the right air duct plate 413 and above the evaporator assembly 33 by threaded fasteners, with the fan assembly 42 being adjacent the supply air outlet 4134. The air flowing through the evaporator unit 33 is cooled and then discharged from the supply outlet 4134 by the fan unit 42.

In other embodiments, the air duct board assembly may also be assembled on the inner wall surface of the foaming cabinet body in other manners such as clamping, riveting, and the like, which satisfy secondary installation.

Therefore, in the scheme, on one hand, each component forming the circulating air duct system can be assembled on the inner wall surface of the foaming cabinet body in a secondary installation mode after the foaming cabinet body is foamed, so that the structure of the circulating air duct system is simplified, the assembling of the circulating air duct system is easy, and the manufacturing cost of the horizontal air-cooled refrigerator with the structure is low. On the other hand, the air duct structure in the circulating air duct system of the embodiment is stable and reliable, and even if the refrigerating chamber is filled with commodities, the normal flow of air flow can be still met in the air duct, so that the temperature of the refrigerating chamber can be kept uniform, and the low-temperature storage of the commodities is facilitated.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
