First, as shown in Figure 6, when the power is applied to the device,

The control means 100 determines whether there is no abnormality in the safety device (step S11).

Here, the safety device is a safety situation detected through the door sensor 191, ozone detection sensor 131, the ultraviolet sensor 147 and the pressure sensor 146 of the first air sterilization means 140, the door It is to judge whether 12 is closed, ozone is detected, or whether the primary air sterilization means 140 is safely operated.

If there is no abnormality in safety at this determination step (S11), that is, the door 12 is closed, ozone is not detected, and the primary air sterilization means 140 is in a normal state, the control means 100 is a door lock. The device 190 is driven to securely lock the door 12 to the main body 11 (step S12).

And the control means 100 starts the sterilization and drying operation (step S13).

Here, the sterilization and drying operation mode will be described with reference to FIG.

When the sterilization and drying operation is started, the control means 100 outputs a voice message indicating the start of the sterilization and drying operation to the speaker 193 (step S21).

Then, the ultraviolet air lamp 144 is turned on by operating the first air sterilizing means 140, and the pressure pump 150 and the second air sterilizing means 160 are operated to generate the ozone generator 161 and the negative ion generator. 162 and the low temperature plasma device 163 are operated. (Step S23, S24)

Then, the heat generating means 170 is operated to drive the heater 171 and the blowing fan 172. (S25 step)

In this way, if the sterilization, drying and deodorization operation proceeds to time count. (Step S26)

Then, it is determined whether an error has occurred during such operation. (Step S27).

If no error has occurred, it is determined whether the already set sterilization, drying and deodorization operation time is completed.

If the sterilization, drying and deodorization operation time already set in the determination step (S28) has not elapsed, the operation is continued, and if that time has elapsed, the ozone generator 161 and the low temperature plasma apparatus of the secondary air sterilization means 160 are passed. The driving of 163 is stopped to stop the generation of ozone and low temperature plasma, and the driving of the heat generating means 170 is stopped (steps S29 and S30).

And the control means 100 outputs a voice message for notifying the end of the sterilization and drying operation to the speaker 193 (step S31).

On the other hand, if an error occurs in the determination step (S27), the error processing mode is performed, which is whether the human body is detected through the human body sensor 111 (only when the human body sensor is employed) as shown in FIG. (Step S51)

When the human body is detected in the determination step S51, the door lock device 190 is driven to release the door lock. (S52) Therefore, if there is a person in the chamber 14, the user can come out of the chamber.

Then, the operation of the ozone generator 161 and the low temperature plasma apparatus 163 of the secondary air sterilization means 160 is stopped, and the ozone decomposition device 130 is driven to perform the ozone decomposition operation. (S53, S54 step)

And if the human body is not detected in the determination step (S51) through the ultraviolet sensor 147 and the pressure sensor 146 of the primary air sterilization means 140 to determine the abnormality of the ultraviolet lamp 144 and filters. (S55 step)

If an abnormality is found in the first air sterilizing means 140 in the determining step S55, the process enters the step S53, and the first air sterilizing means 140 in the determining step S55. If there is no abnormality, it is determined whether the door 12 is opened through the door sensor 191 (step S56).

If the opening of the door 12 is detected in the determination step S56, the process enters the step S53. If the opening of the door 12 is not detected, it is determined whether the power is cut off (step S57).

If the power is not cut off in the determination step S57, the flow goes to the step S53, and if the power is cut off, the emergency battery 195 is driven.

Returning to the main mode (FIG. 6) again, when the sterilization and drying operation as described above is completed, the control means 100 starts the ozone decomposition operation (step S14).

Here, the ozone decomposition operation mode will be described with reference to FIG. 8.

When the ozone decomposition operation is started, the control means 100 drives the ozone decomposition device 130 and outputs a voice message informing the speaker 193 of the start of the ozone decomposition operation (step S41).

When the ozone decomposition operation proceeds as described above, a time count is performed.

Then, it is determined whether the door 12 is opened during the operation, and when the door 12 is opened, a voice message warning the door opening is output to the speaker 193. (steps S43, S44)

Here, when the door 12 is not opened, it is determined whether the exhaust gas decomposition time (ozone decomposition time) has ended, and when the exhaust gas decomposition time is finished, the first air sterilization means 140 and the second air sterilization means The driving of the negative ion generator 162 of the means 160 is stopped. (Step S45, S46)

Then, it is determined whether the power is cut off to use the battery 195 (step S47).

If the battery is not used in the determination step (S47), ozone decomposition is terminated, and if the battery is used, the above-mentioned safety device is released and the power is turned off.

Returning back to the main mode (FIG. 6), when the ozone decomposition operation as described above is completed, the control means 100 releases the door lock of the door lock device 190 to release the safety device (step S15).

And the storage mode is entered (step S16).

Here, the storage mode will be described with reference to FIG. 10.

When the storage operation is started, the control means 100 outputs a voice message notifying the start of entering the storage mode to the speaker 193 (step S61).

Then, the first air sterilization means 140 is operated to start a sterilization operation, and the negative ion generating device 162 of the second air sterilization means 160 is generated to generate negative ions (steps S62 and S63).

Then, the temperature of the heat generating means 170 is adjusted to maintain the proper temperature and humidity inside the chamber 14.

Then, it is determined whether the sterilization and drying operation is started, and returns to the main mode if the sterilization and drying operation is started.
