In this bathroom air conditioner 1, regardless of which operation is executed, at the end of operation, the damper 18 is positioned at the first position in which the ventilation-side ventilation passage 102 is closed and the circulation-side ventilation passage 101 is fully opened. However, the damper motor 18b may be controlled so that the damper 18 is positioned at the first position when the silver ion mist spraying operation is started.

(Silver ion mist spray treatment)
When a request for silver ion mist spraying operation is generated by a user operating the remote controller R or a preset timer function, the controller 7 starts the silver ion mist spraying process according to a program.

In the silver ion mist spraying process, the control device 7 first causes the speaker 70 of the remote controller R to issue a predetermined start guidance (for example, "Silver ion sterilization will start. Please do not enter the bathroom") ( step S1). This can alert the user to start the silver ion mist spraying operation.

When the start guidance is notified, the standby timer is started (step S2), and the operation of the fan 13 is started (step S3). When a predetermined waiting time (for example, 1 minute) elapses and the waiting timer times out (Yes in step S4), the detection signal from the human sensor 19 continues for a predetermined time (for example, 10 seconds). Then, it is determined whether or not there is a person in the bathroom 4 (step S5). Although not shown, if the presence of a person in the bathroom 4 is detected by the human sensor 19 when the waiting time has elapsed (Yes in step S5), the speaker 70 is caused to announce the start guidance again. When the presence of a person in the bathroom 4 is continuously detected by the human sensor 19 even after the re-notification, the operation stop guide is notified to stop the operation.

If the presence of a person in the bathroom 4 is not detected by the human sensor 19 when the standby time has elapsed (No in step S5), the mist spray buzzer that starts spraying silver ion mist is notified from the speaker 70. (Step S6).

Next, the water supply electromagnetic valves 52 and 53 are opened (step S7). Also, a purge timer is started (step S8), and water is supplied from the water supply passage 50 to the mist nozzle 30 for a predetermined purge time (for example, 50 seconds). As a result, the pipes are washed, the water remaining in the pipes is replaced, and the silver ion generation unit 60 is filled with water, so that mist can be stably sprayed from the mist nozzles 30 . When the purge time elapses and the purge timer times out (Yes in step S9), energization to the electrodes is started in order to operate the silver ion generation unit 60 (step S10). Thereby, a voltage is applied to the electrodes and the silver ions are eluted into the water.

When the silver ion generation unit 60 is activated, the first spray timer is started (step S11), and the movable louver 16 is moved so that the silver ion mist is sprayed toward the front wall 42 of the bathroom 4 by the air blown by the fan 13. By rotating, the movable louver 16 is held at the predetermined first spraying position for a predetermined first spraying time (for example, 40 seconds) (step S12). As a result, silver ion mist is continuously sprayed toward the front wall 42 while the movable louver 16 is held at the first spray position, so the bathroom air conditioner 1 is provided near the rear wall 43. Also, the front wall 42 can be efficiently sprayed with silver ion mist.

When the first spray time elapses and the first spray timer times out (Yes in step S13), the second spray timer is started (step S14) so that the silver ion mist is sprayed toward the washing area 45. , the movable louver 16 is rotated, and the movable louver 16 is held at the predetermined second spraying position for a predetermined second spraying time (for example, 15 seconds) (step S15). As a result, while the movable louver 16 is held at the second spraying position, the silver ion mist is continuously sprayed toward the washing space 45, so that the silver ion mist is efficiently sprayed onto the floor surface of the washing space 45. be able to.

When the second spray time elapses and the second spray timer times out (Yes in step S16), the third spray timer is started (step S17), and the silver ion mist is sprayed toward the rear wall 43 side of the bathtub 44. is sprayed, and the movable louver 16 is swung at a predetermined third spray position for a predetermined third spray time (for example, 30 seconds) (step S18). As a result, while the movable louver 16 is swung at the third spray position, the air blown from the outlet 122 forms a turbulent flow, and the silver ion mist is efficiently sprayed from the bathtub 44 over the rear wall 43. can do.

(Water mist spray treatment)
When the third spraying time has elapsed and the third spraying timer times out (Yes in step S19), and the silver ion mist spraying process ends, the water mist spraying process continues. In this water ion mist spraying process, first, the electricity to the electrodes of the silver ion generation unit 60 is stopped to stop the operation of the silver ion generation unit 60, the fan 13 is stopped, and the cleaning spray timer is started (step S20-S22). Next, the movable louver 16 is rotated so that the air outlet 122 is slightly opened by the first rectifying plate 161, and the movable louver 16 is moved to a predetermined cleaning position (for example, 50 seconds) for a predetermined cleaning spray time (for example, 50 seconds). For example, the intersection angle θs between the hole axis of the mist nozzle 30 shown in FIG. 6 and the extension line of the first rectifying plate 161 in the front-rear direction is maintained at about 60 degrees to about 80 degrees (step S23). As a result, water mist is continuously sprayed from the mist nozzle 30 toward the movable louver 16 . At this time, the fan 13 is stopped and the outlet 122 is substantially closed by the movable louver 16, so the water mist cleaning liquid sprayed on the movable louver 16 turns into water droplets and flows into the bathtub 44 below. Dripping. When the cleaning spray time elapses and the cleaning spray timer times out (Yes in step S24), the water supply electromagnetic valves 52 and 53 are closed (step S25) to end the water mist spraying process.

When the water mist spraying process ends as described above, the drying operation is started (step S26). Although not shown, in this drying operation, the fan 13 is operated again, the damper 18 is moved to the already-described third position, hot water is supplied from the water heater to the heat exchanger 14, and the set drying time is reached. A part of the air in the bathroom 4 is discharged to the outside while blowing warm air to the bathroom 4.

As described above in detail, according to the present embodiment, when there is a request to execute the silver ion mist spraying operation, the silver ion generation unit 60 and the fan 13 are operated, and the movable louver 16 is moved to the bathroom 4 or the mist spraying operation. The silver ion mist is sprayed into the bathroom 4 from the mist nozzle 30 through the outlet 122 by rotating it to a predetermined spray position according to the structure of the nozzle 30 . Therefore, silver ions can be deposited over a wide area in the bathroom 4 .

Further, according to the present embodiment, after the silver ion mist spraying process, the silver ion generating unit 60 and the fan 13 are stopped, and with the movable louver 16 held at a predetermined cleaning position with respect to the mist nozzle 30, the mist is sprayed. Since the water mist spraying process of spraying water mist onto the movable louver 16 from the nozzle 30 is executed, the high-concentration silver ions adhered to the movable louver 16 by the silver ion mist spraying process can be washed away by the water mist. As a result, blackening of the movable louver 16 due to silver ions can be prevented, and deterioration of aesthetic appearance can be prevented. In particular, in the water mist spraying process, the movable louver 16 is held at the cleaning position and the fan 13 is stopped, so that the water mist sprayed onto the movable louver 16 can be reduced. In addition, since the movable louver 16 is sprayed with water mist having a small particle diameter, silver ions adhering to a wide range of the movable louver 16 can be efficiently washed away. During the water mist spraying process, the cleaning liquid containing silver ions drips into the bathtub 44, but the silver ion concentration in the cleaning liquid is reduced by the water mist. is lowered, blackening of the bathtub 44 can also be prevented.

In addition, according to the present embodiment, since the presence sensor 19 confirms that no one is in the bathroom 4, the silver ion mist is sprayed, so the high-concentration silver ion mist having a high sterilization effect is sprayed. be able to. In addition, it is possible to prevent the washing liquid dripping when washing the movable louver 16 from splashing on a person.

In addition, in the present embodiment, the drying operation is performed after the silver ion mist spraying operation, so that the silver ions can adhere to the wall surface before the silver ions sprayed into the bathroom 4 run off the wall surface. , a high sterilization effect can be obtained. Also, even if warm air passes through the movable louver 16 during the drying operation, the silver ions adhering to the movable louver 16 are washed away before the drying operation, so darkening due to drying of the silver ions can be reliably prevented. .

Therefore, according to the present embodiment, it is possible to efficiently sterilize a wide area in the bathroom 4 with silver ions, and prevent the movable louver 16 from darkening due to the silver ions, thereby preventing deterioration of the appearance. can be done.
