Furthermore, the horizontal refrigerator 100 is not easy to adhere to the glass door body above the inner container 20 due to the downward-inclined air supply through the air outlet by the external evaporator chamber 50, and the phenomenon of glass door surface condensation caused by the diffusion of air onto the glass door body is reduced.

In summary, the invention provides a horizontal refrigerator, wherein the evaporator chamber is externally arranged below the first step part of the cabinet, and the evaporator chamber is directly arranged below the first step part outside the cabinet, which is beneficial to simplifying the assembly process of the evaporator module. In addition, the evaporator cavity and the compressor assembly are integrated to form an external system module, and the external system module is directly installed in the containing space below the first step part of the case shell, so that the installation process can be simplified, and the assembly convenience is improved.

The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention.
