Based on the premise that the cabinet opening 3 is discharged from three sides, the upper part of the storage cavity 20 is formed to form a four-sided air outlet effect to increase the horizontal air volume. Due to the principle of natural sinking of cold energy, the cold energy generated in the upper part naturally flows to the bottom of the storage cavity 20, and the cold energy fully covers the storage cavity 20. The cooling effect is better and the temperature uniformity of the storage cavity 20 is improved.

[0106] The lower part of the vertical air duct plate 61 is provided with a return air port 612 connecting the storage cavity 20 and the evaporator cavity 63. In this embodiment, the upper air outlet and lower air return are formed. Based on the principle of natural sinking of cold energy, the cold energy generated at the top naturally flows to the bottom of the storage cavity 20, and then returns to the evaporator cavity 63 through the return air port 612 provided at the bottom, which has the advantage of reasonable design of the air outlet and return air paths.

[0107] Preferably, the second air outlet 611 includes a plurality of second air outlet holes arranged at intervals in the horizontal direction. The second air outlet holes may be openings in the shape of hexagon, circle, ellipse, quadrilateral, etc.

[0113] Combination Figures 10 to 12 As shown, further, the cabinet opening member 3 includes a cabinet opening main body for forming an air outlet cavity 35, a step portion 38 formed by the cabinet opening main body extending toward the box shell 1, and a clamping portion 39 extending downward from the step portion 38 and clamped with the box shell 1. The cabinet opening main body is connected to the inner tank 2. The first cabinet opening member 31, the third cabinet opening member 33, the second cabinet opening member 32, and the fourth cabinet opening member 34 are connected to form the cabinet opening main body.

[0114] The box shell 1 includes a box body, and a U-shaped clamping portion 11 formed by bending the edge of the box body to be clamped with the clamping portion 39. The U-shaped clamping portion 11 has a U-shaped clamping groove 111 which is opened upward and is provided for the clamping portion 39 to be clamped. When the clamping portion 39 is installed in the U-shaped clamping portion 11 through the U-shaped clamping groove 111, the U-shaped clamping portion 11 is elastically deformed to allow the clamping portion 39 to be installed. After the clamping portion 39 is installed, the U-shaped clamping portion 11 restores the elastic deformation and clamps the clamping portion 39.

[0115] The clamping part 39 includes a clamping body 391 formed by the step part 38 extending downward, and an outer protrusion 392 extending outward from the clamping body 391 to abut against the inner wall of the U-shaped clamping part 11. The inner wall of the U-shaped clamping part 11 forms an abutment part that abuts against the outer protrusion 392. The outer protrusion 392 is used to make the U-shaped clamping part 11 naturally produce elastic deformation. The installation method is simple and easy to position and install.

[0116] Compared with the prior art, the horizontal refrigerator provided by the present invention defines a storage cavity 20 by the inner liner 2 and the cabinet opening 3. The storage cavity 20 includes the internal space defined by the cabinet opening 3, which increases the space of the storage cavity 20. By preforming the air outlet cavity 35 on the cabinet opening 3, and connecting the cabinet opening 3 with the inner liner 2 to form a whole, the design of the air duct cover plate and the air duct cavity embedded parts of the prior art is cancelled, and an air inlet connected to the refrigeration unit 5 is formed on the cabinet opening 3. The cold energy generated by the refrigeration unit 5 is sent to the air outlet cavity 35 through the air inlet, and then the air is sent to the storage cavity 20 through the air outlet cavity 35. The air outlet cavity 35 is arranged at the upper part of the box body, forming an upper air outlet mode. Based on the principle of natural sinking of cold energy, the cold energy generated at the top naturally flows to the bottom of the storage cavity 20, so that the cold energy of the storage cavity 20 is evenly distributed. It has the advantages of compact structure, simple process, easy assembly, reduced overall cost, high refrigeration efficiency, and uniform refrigeration.
