Detailed ways

The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and provides detailed implementation modes and specific operation processes, but the protection scope of the present invention is not limited to the following implementations example.

Referring to FIG. 1, the present embodiment discloses a horizontal air-cooled refrigerator, including a box body 1 and a door body 2 located on the top of the box body 1. The box body 1 is provided with a compartment, and the box body 1 is provided with an air duct system , the air duct system includes an evaporator 8, a fan 7, a supply air duct, and a return air duct. The evaporator 8 is located in the evaporator cavity, the evaporator cavity is located on the rear side of the compartment, and the bottom of the evaporator cavity is provided with defrost drainage. Hole 9, below the defrost drainage hole 9 is the compressor compartment 10. The fan 7 is located above the evaporator 8, and the compartment is covered with an air hood on the front side of the evaporator cavity and the fan 7. The air hood is provided with a plurality of air hood air outlets 6, and the left and right sides of the compartment are provided with a hood. The air outlet beam 4, the front and rear sides of the air outlet beam 4 are respectively provided with a plurality of beam air outlets, the front side is the beam front air outlet 5, the rear side is the beam rear air outlet 5, and the plurality of beam air outlets pass through. The air inlet air duct is communicated with the upper part of the evaporator cavity.

Wherein, the inside of the air outlet beam 4 is a hollow beam channel, a plurality of beam outlets are connected with the beam channel, the left side wall and/or the right side wall of the compartment is provided with an air supply duct, and the beam channel passes through the side wall of the compartment The supply air duct is communicated with the top of the evaporator chamber. The plurality of beam air outlets on the front side of the air outlet beam 4 are arranged in two rows up and down, and the plurality of beam air outlets on the rear side of the air outlet beam 4 are arranged in two rows up and down. The plurality of air hood air outlets 6 on the air hood are arranged in three rows: upper, middle and lower.

An air hood return port 11 is arranged at the bottom of the air hood, and the air hood return air port 11 communicates with the lower part of the evaporator cavity through a return air duct.
