Description

Technical Field

[0001] The invention relates to a disinfection cabinet, in particular to an air circulation device of the disinfection cabinet. Background Art

[0002] Currently, most star-rated disinfection cabinets on the market use a centrifugal fan to blow air into the cavity to achieve uniform temperature and ozone concentration within the disinfection cabinet. This common solution can be divided into two options: Option 1 uses a centrifugal fan to blow air into the cavity alone. Because the cavity is relatively confined, air circulation is impeded, so achieving uniform temperature takes a longer time, thereby increasing the drying time. During drying, water vapor generated from water vapor is retained in the cavity. As the temperature inside the cavity cools, the water vapor liquefies again, and water droplets condense on the inner walls of the disinfection cabinet and on the tableware. Option 2 uses a centrifugal fan to draw air from the cavity and blow it back into the cavity. This allows for smooth air circulation and uniform temperature within the cavity, thereby shortening the drying time. However, Option 2 also suffers from the problem that the water vapor cannot be completely discharged during drying, and water droplets condense on the inner walls of the disinfection cabinet and on the tableware during cooling. Summary of the Invention
