Therefore, the air outlet and the return air are respectively disposed on the first liner wall 23 and the second liner wall 24, which shortens the air supply and return air distance and effectively maintains the temperature balance in the liner. Further, the horizontal freezer 100 passes through the external evaporator chamber 50 and blows down the air through the air outlet, so it is not easy to form a bond with the glass door above the liner 20, reducing the spread of wind to the glass door to cause glass The phenomenon of condensation on the door surface.

In summary, the present invention provides a horizontal freezer, the evaporator chamber is placed below the first step of the cabinet, and the evaporator chamber is directly installed below the first step outside the cabinet, which is beneficial to simplify evaporation Assembly process of the module. In addition, integrating the evaporator chamber and the compressor assembly to form an external system module, and directly installing the external system module into the storage space below the first step portion of the casing, can further simplify the installation process and improve the convenience of assembly.

Of course, there can be many other embodiments of the present invention. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes And variants shall fall within the scope of protection of the claims appended to the present invention.
