In step S4, the first ultrasonic transducer 7 is driven for a second predetermined time (<first predetermined time, for example, 1 minute) (that is, after the second predetermined time has elapsed from the start of driving, the first ultrasonic transducer 7 is driven). The sterilization liquid stored in the sterilization liquid storage unit 3 is atomized. Thereby, the spraying apparatus 1 discharge | releases the nebulized disinfecting liquid for 2nd predetermined time. At this time, the drive start time or drive stop time of the first ultrasonic transducer 7 is stored.

In step S5, it is determined whether or not a third predetermined time (> first predetermined time, for example, 60 minutes) has elapsed since the activation of the timer (or the start of driving of the second ultrasonic transducer 13). If the third predetermined time has not elapsed, the process proceeds to step S6. If the third predetermined time has elapsed, the process proceeds to step S7.
In step S <b> 6, it is determined whether or not the first predetermined time has elapsed from the start (or stop of driving) of the first ultrasonic transducer 7. If the first predetermined time has not elapsed, the process returns to step S5, and if the first predetermined time has elapsed, the process returns to step S4.
In step S7, the driving of the second ultrasonic transducer 13 is stopped and the timer is cleared.

As a result, the room is humidified and the sterilizing solution is intermittently sprayed into the room, which is effective in preventing influenza diseases in winter, for example.

In step S8, as in step S2, the built-in timer is started, and the second ultrasonic transducer 13 is driven to atomize the water stored in the water storage unit 9. Thereby, the spraying device 1 discharges the atomized water into the room and starts humidification in the room.
In step S9, it is determined whether or not the third predetermined time has elapsed from the start of the timer (or the start of driving of the second ultrasonic transducer 13), and when the third predetermined time has elapsed, the process proceeds to step S10.
In step 10, the driving of the second ultrasonic transducer 13 is stopped and the timer is cleared.

  When the humidification mode is selected in the above steps S8 to S10, the spray device 1 continues to discharge the atomized water into the room for a third predetermined time (for example, 60 minutes). Thereby, the room | chamber interior which can operate the spraying apparatus 1 as a general humidifier can be humidified.

In step S11, the built-in timer is started, and the first ultrasonic transducer 7 is driven to atomize the sterilization liquid stored in the sterilization liquid storage unit 3. Thereby, the spraying apparatus 1 discharge | releases the atomized sanitization liquid indoors, and starts indoor sanitization and deodorization.
In step S12, it is determined whether or not the third predetermined time has elapsed from the start of the timer (or the start of driving of the first ultrasonic transducer 7), and when the third predetermined time has elapsed, the process proceeds to step S13.
In step S13, the driving of the first ultrasonic transducer 7 is stopped and the timer is cleared.

  When the sterilization / deodorization mode is selected from the above steps S11 to S13, the spray device 1 continues to discharge the atomized water into the room for a third predetermined time (for example, 60 minutes). Thereby, the spraying apparatus 1 can be operated with the sterilization / deodorization apparatus, and the room can be effectively sterilized / deodorization.

  The first to third predetermined times can be set as appropriate, and different values may be set in each mode. Further, in the sterilization / deodorization mode, the atomized sterilization solution may be intermittently released until the third predetermined time elapses.

  The spray device 1 according to the present embodiment has a plurality of operation modes and operates in an operation mode selected by the user. That is, when the normal operation mode is selected, the spray device 1 performs indoor humidification and sterilization / deodorization together for a third predetermined time. When the humidification mode is selected, the spray device 1 operates as a general humidifier that humidifies the room for a third predetermined time. Further, when the sterilization / deodorization mode is selected, the spray device 1 operates as a sterilization / deodorization device that sterilizes / deodorizes the room for a third predetermined time. That is, since one spraying device has a humidifying function and a sterilizing / deodorizing function, it is particularly effective for preventing influenza diseases. In addition, there is an advantage that the installation space can be reduced as compared with the case where the humidifier and the sterilizer are provided separately.
