Next, the operation of the humidifier of Embodiment 1 will be described with reference to FIG.
FIG. 6 is a diagram showing a change in rotational speed during normal operation and scale cleaning operation of the blower in the humidifier according to the first embodiment.
When the controller detects that the humidifying operation (normal operation) start switch on provided on the operation panel 6 is turned on, the controller controls the fan 8 to be driven at a predetermined rotational speed as shown in FIG. Is driven to rotate the plurality of disks 9. At this time, the indoor air is sucked into the main body case 1 from the air inlet 4 by the blower 8, and the water 10 in the water storage tank 7 is scraped up by the rotation of the disk 9. The water 10 thus scooped up is vaporized by the sucked air and discharged from the humidified air discharge port 5 into the room.

  After performing the humidifying operation, the control unit determines whether the water level in the water storage tank 7 periodically detected by the water level detection unit has become a predetermined value or less. When the water level detected by the water level detection unit falls below a predetermined value, the control unit notifies the operator that the disk 9 has been subjected to scale cleaning via the operation panel 9. This notification is made, for example, by blinking an LED and by a buzzer or sound. After the notification, the control unit stops driving the blower 8 as shown in FIG. 6 when detecting a preset switch-on operation. Then, the support shafts 27 and 28 are rotated toward the disk 9 to bring the cleaning liquid outflow parts 21 and 211 and the cleaning liquid collection parts 23 and 231 to predetermined positions. Then, the control unit drives the pump 22 of the cleaning liquid supply unit.

  When the pump 22 is driven, the cleaning liquid 40 in the cleaning liquid recovery tank 24 is sucked and introduced into the cleaning liquid outflow portions 21 and 211 via the flexible tube 26. The cleaning liquid 40 introduced into the cleaning liquid outflow portion 21 is dropped from a plurality of holes and added to the exposed surface on one side of the front and back discs 9. The cleaning liquid 40 introduced into the cleaning liquid outflow portion 211 is dropped from a plurality of holes 211a provided on both sides and added to the exposed surface of the disk 9 disposed on both sides. At this time, the scale attached to each disk 9 is dissolved by the cleaning liquid 30 added to the exposed surface. Then, the cleaning liquid 30 is wiped off by the respective cleaning liquid collecting sections 23 and 231 disposed below the cleaning liquid outflow sections 21 and 211, and flows into the grooves 23a and 231a provided in the respective cleaning liquid collecting sections 23 and 231. Then, the cleaning liquid 40 is recovered in the cleaning liquid recovery tank 24 via the flexible tube 25. Accordingly, the cleaning liquid 40 is circulated while the pump 22 is being driven, and the scale attached to the disk 9 is dissolved.

  On the other hand, the controller determines, for example, whether or not a predetermined time has elapsed since the pump 22 was driven. When the predetermined time has elapsed, it is determined that the cleaning of the scale has been completed. The driving of 22 is stopped and the supply of the cleaning liquid 40 is stopped. Next, the cleaning liquid outflow portions 21 and 211 are separated from the disk 9 by rotating the support shaft 27 in the direction opposite to the previous rotation direction. Next, the support shaft 28 is rotated in the same direction as described above, and the cleaning liquid collection units 23 and 231 are separated. As shown in FIG. 3B, the cleaning liquid outflow portions 21 and 211 and the cleaning liquid collection portions 23 and 231 rotate the respective support shafts 27 and 28 until they are in an upright state. Thereafter, the control unit drives the stopped blower 8 so that humidification is performed again.

As described above, in the first embodiment, the cleaning liquid 40 in the cleaning liquid recovery tank 24 is sucked by driving the pump 22 and dropped from the cleaning liquid outflow portions 21 and 211 to expose the disk 9 toward the water surface in the water storage tank 7. The cleaning liquid 40 is added to the surface and the cleaning liquid 40 added to the exposed surface is wiped off by the cleaning liquid collecting units 23 and 231 and is recovered in the cleaning liquid recovery tank 24. Therefore, the scale attached to the disk 9 can be removed with a simple configuration and without using a large amount of the cleaning liquid 40, and deterioration of the disk 9 can be minimized. Further, the cleaning liquid 40 can be used repeatedly, and the water 10 in the water tank 7 is not contaminated with the cleaning liquid 30.
Further, in the first embodiment, when the scale cleaning is performed, the driving of the blower 8 is stopped, so that the cleaning liquid 40 can be prevented from being scattered. Further, since the cleaning liquid outflow parts 21 and 211 and the cleaning liquid collection parts 23 and 231 are separated from the disk 9 during the humidification operation, the wear of the cleaning liquid collection parts 23 and 231 in contact with the disk 9 is suppressed. be able to.

In the first embodiment, when the scale cleaning is performed, the driving of the blower 8 is stopped. However, as shown in FIG. 7, the rotational speed of the blower 8 is made lower than the rotational speed in the humidifying operation. May be. The decrease in the rotational speed of the blower 8 is a speed at which the cleaning liquid 40 is not scattered. In this case, it is possible to continue the humidification operation without stopping even if the scale cleaning is performed.
Further, when the water level detected by the drive water level detection unit is below a predetermined value, the disk 9 is informed of the scale cleaning, and the pump 22 of the cleaning liquid supply unit is turned on when a preset switch-on operation is detected. However, the pump 22 of the cleaning liquid supply unit may be automatically driven when notification of scale cleaning is given.

  Furthermore, in the first embodiment, the rotation speed of the disk 9 is not changed when entering the scale cleaning, but the rotation speed of the disk 9 may be lower than the rotation speed during the humidifying operation. In addition, when the scale cleaning is started, the rotation direction of the disk may be opposite to the rotation direction during the humidifying operation. When controlled in this way, the scale attached to the disk 9 can be removed more efficiently.
