ABSTRACT:
When an ultraviolet pasteurizer is used in a room free of a person, left and right light shield doors are opened to expose ultraviolet lamps outwardly. When an operation switch on a control panel is then turned on, an operation start timer is actuated, and the ultraviolet lamps are then energized to sterilize surrounding surfaces after elapse of 5 minutes. When the ultraviolet pasteurizer is used in a room occupied by a person, the left and right light shield doors are closed to direct the ultraviolet lamps inwardly until all light shield doors are brought into a substantially triangular prism. When the operation switch on the control panel is then turned on, the ultraviolet lamps and a fan are energized to draw external air from an air inlet. The drawn air passes through an inner radiation chamber defined inwardly of the light shield doors that have been combined into the substantially triangular prism. The air is sterilized by ultraviolet radiation emitted from the ultraviolet lamps and discharged from an air outlet.
