Further, the control unit 12 has a timer function so that on / off control of each device can be automatically performed when a set time comes.

The operation of the deodorizing / sterilizing apparatus according to the present invention in the above configuration will be described with reference to the operation example of FIG. In the figure, C means closed, O means open, and Δ means the same as the previous control mode. Here, deodorization and sterilization are performed one by one from the room 1c.

In the operation example shown in FIG. 2, the motor dampers 7a, 7b, 7c, 9a, 9b, 9
Each of c is open, and the ozone generator 5, the air supply fan 8, and the exhaust fan 11 are turned off. This state is continued until 11:00 pm.

[0023] Usually, nobody is left in the room.
At the time, the control unit 12 is driven so that the ozone generator 5 is turned on (ON). At the same time, the control unit 12 switches the solenoid valve 3c to open and switches each of the motor dampers 7a, 7b, 7c, 9a, 9b, 9c to close. By this control, the ozone generated by the ozone generator 5 is discharged into the chamber 1c through the route of the header 4, the solenoid valve 3c, and the pipe 2c. This ozone release is performed over 2 hours until 1:00 am on the following day.

At 1:00 a.m., the control unit 12 keeps the ozone generator 5 turned on while the air supply fan 8 and the exhaust fan 11
, The solenoid valve 3b is switched to open, the solenoid valve 3c is switched to close, and the motor dampers 7c and 9c are switched to open. With this control, the object of deodorization / sterilization by the ozone generator 5 is moved from the room 1c to the room 1b. At the same time, outside air from the air supply fan 8 is supplied only to the room 1c through the motor damper 7c, and the ozone in the room is exhausted outside the building in the process of being sucked in from the motor damper 9c, thereby preventing ozone from remaining. This condition lasts 2 hours until 3:00 am

At 3:00 am, the solenoid valve 3b is switched to close and the solenoid valve 3a is switched to open by the control unit 12, and the object of deodorization and sterilization is moved from the room 1b to the room 1a to generate ozone. Ozone from the vessel 5 is released only into the chamber 1a to perform deodorization and sterilization.
Further, the controller 12 closes the motor damper 9c and opens the motor damper 9b, and also closes the motor damper 7c and switches the motor damper 7b to open.

a is opened, the outside air from the air supply fan 8 is introduced into the chamber 1a, and the ventilation of the chamber 1a is started so that the air can be exhausted from the motor damper 9a. This ventilation takes place for 2 hours.

Next, at 7:00 am, the control unit 12 turns off and closes all devices. That is, the ozone generator 5, the air supply fan 8, and the exhaust fan 11 are turned off, all the solenoid valves 3a, 3b, 3c are closed, and the motor dampers 7a, 7b, 7c, 9a, 9b,
9c is opened, and the deodorization / sterilization processing and the indoor ventilation processing are completed.

In the above embodiment, the deodorizing / sterilizing treatment is performed one room at a time . However, if the ozone generator 5 can be made large, ozone can be supplied to a plurality of rooms at the same time. It is possible.

By the way, there is a safety problem in releasing ozone while a person is present in any of the rooms 1a, 1b, 1c. Therefore, it is required to prevent erroneous release of ozone while in the room. A control example for this will be described with reference to FIG.

FIG. 3 is a flowchart showing control for preventing erroneous ozone release. First, when a start button (not shown) of the operation panel 13 is operated, a processing start command is issued (step 301). After this command, if it is determined that the start time (23:00) shown in FIG. 2 has been reached (step 302), it is determined whether the lighting switch of the target room for the deodorization / sterilization processing is on. (Step 303). If the lighting switch is on, it can be determined that there is a person in the processing target room, and a text message such as "there is a person" is displayed to the operator of the operation panel 13 or a warning lamp is turned on ( Step 304).

On the other hand, if the lighting switch is off, it is determined that no one is present, and the solenoid valve corresponding to the processing target room is controlled (closed to open) (step 305).
Together with the ozone generator 5 (step 30)
6). Then, a warning is given by a buzzer or the like so that a person entering the room can be warned that ozone is being released (step 307). Thereafter, a series of controls shown in FIG. 2 is executed.

Alternatively, the power supply of the ozone generator 5 may be changed from the midnight power supply, and the ozone generator 5 may be unilaterally stopped at a certain time. In addition, running cost can also be reduced by using midnight power.

If an ozone generator 5 capable of generating both ozone air and ozone water is used, the ozone generator 5 is used as washing water for kitchen floors during the daytime, and ozone air is deodorized at nighttime.
It can be used for sterilization treatment, and can reduce equipment costs and increase the utilization efficiency of equipment.

Further, in the above embodiment, the processing target is three rooms. However, any processing can be performed as long as the number of solenoid valves and motor dampers is increased.
