In addition, an ozone generated by adding an inlet fan (not shown) may be evenly dispersed in the sterilizer.

As shown in FIG. 4, when the power is turned on, the controller 302 for executing the software according to the present invention executes the initialization in the initialization state S1 and then proceeds to the main state S2. When an operation for setting is input in the main state (S2), the state transitions to the setting state (S7) and sets setting values such as disinfection time, disinfection concentration, and voice support. When the setting is completed, the state transitions back to the main state (S2), and when ozone disinfection is operated in the main state (S2), the process moves to the disinfection preparation state (S3) and checks the corresponding part, and when the start operation is input, the disinfection state (S4). Proceed to start disinfection. If an error is detected in the disinfection preparation state (S3), the transition to the disinfection failure state (S6). In the disinfecting state (S4), the vacuum air pump 331 operates to inhale the air in the chamber, generates ozone gas, and supplies the chamber 330 again through the valve 314 to supply medical equipment by the ozone gas in the chamber. Will be disinfected.

After the disinfection is completed, the process returns to the disinfection preparation state (S3), and the process proceeds to the main state (S2). If the stop operation is input or the door open is detected in the disinfection state (S4), the process proceeds to the disinfection stop state (S5), and if the restart button is input within 10 seconds after the transition to the disinfection stop state (S5) and all the states are normal Proceed back to disinfection state (S4). If the start button is operated after 10 seconds have elapsed after the transition to the disinfection stop state (S5), the process returns to the disinfection preparation state (S3) and starts again.

If all of the conditions are not satisfactory in the disinfection stop state (S5), the state transitions to the disinfection alarm state (S6) and an alarm is displayed.
