Patent ID: 8083999

Claim:
A sterilizing apparatus for sterilizing articles received in a chamber, comprising (a) a sterilizing gas generator that supplies sterilizing gas into the chamber, selected from one of a generator that atomizes a sterilizer solution by means of an ultrasonic vibrator and a gas generator that evaporates a sterilizer solution by dipping an absorbing member into the sterilizer solution, and (b) an ultraviolet generator that irradiates gas in the chamber with an ultraviolet ray; the chamber enclosed by a box-body having a rear wall spaced from a rear wall of the box body to form a duct having an inlet communicating with the chamber provided at an upper side of the duct and having a circulating fan inside the duct at the inlet, an outlet provided at a lower side of the duct, with the ultraviolet generator arranged to decompose sterilizing gas circulating in the duct; a controller that performs a sterilization process for filling the chamber with the sterilizing gas for a predetermined period of time and a decomposition process for decomposing the sterilizing gas by irradiating the gas in the chamber with the ultraviolet ray by means of the ultraviolet generator, and a door for blocking an opening of the chamber in a free-opening/closing manner and a locking device for prohibiting the door from being opened, wherein the controller controls the locking device to prevent the door from being opened from start of the sterilization process to end of the decomposition process.
