Ultraviolet pasteurizer
First Claim
1. An ultraviolet pasteurizer comprising:
- an ultraviolet lamp;
a light shield door having the ultraviolet lamp mounted thereon, said light shield door being openable and closable to block or pass ultraviolet radiation emitted from said ultraviolet lamp;
an inner radiation chamber definable inwardly of said light shield door when said light shield door is closed;
an air inlet and an air outlet providing communication between said inner radiation chamber and an external space;
a fan for introducing air from the external space via said air inlet into said inner radiation chamber, displacing the air near said ultraviolet lamp, and discharging the air from said air outlet; and
a main body, said light shield door being angularly movably supported on said main body, the arrangement being such that when the ultraviolet radiation emitted from said ultraviolet lamp is to be radiated outwardly, said light shield door is angularly moved and held on said main body to expose said ultraviolet lamp outwardly, and when the ultraviolet radiation emitted from said ultraviolet lamp is to be radiated into said inner radiation chamber, said light shield door is angularly moved and held on said main body to direct said ultraviolet lamp into said inner radiation chamber.

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.

10. An ultraviolet pasteurizer comprising:
-
an ultraviolet lamp;
a light shield door openable and closable to block or pass ultraviolet radiation emitted from said ultraviolet lamp;
an inner radiation chamber definable inwardly of said light shield door when said light shield door is closed;
an air inlet and an air outlet providing communication between said inner radiation chamber and an external space;
a fan for introducing air from the external space via said air inlet into said inner radiation chamber, displacing the air near said ultraviolet lamp, and discharging the air from said air outlet, the light shield door, the light shield door being rotatable by 180°
