Description

Horizontal freezer

This application claims the priority of the Chinese patent application with the application date of December 24, 2018, the application number of 201811585077.4, and the invention titled "horizontal freezer", the entire content of which is incorporated by reference in this application.

Technical field

The invention relates to the technical field of refrigeration equipment, in particular to an air-cooled horizontal freezer.

Background technique

Horizontal freezer is a kind of refrigeration equipment that keeps a constant low temperature. It is a kind of electrical appliance commonly used in life to store food or other items at low temperature, and is widely used in commercial and household fields.
