[0061] Since the lower water supply guide 110 is disposed outside the inner case, the lower water supply guide 110 is prevented from contacting the blower 60. A plurality of lower water supply guides 110 may be provided based on the number of the protruding parts 104. That is, in a case in which the lower water supply guide 110 includes four protruding parts 104, four lower water supply guides 110 may be provided.
[0062] The lower water supply guide 110 may have a water channel P2 defined therein such that the water channel P2 is open in a vertical direction. An outlet 118 may be formed in the lower end of the lower water supply guide 110. The outlet 118 of the lower water supply guide 110 may face the interior of the water tub 20. Water flowing along the lower water supply guide 110 falls to the water tub 20.
[0063] The lower water supply guide 110 may be configured as a single duct. In this embodiment, three duct parts 112, 114, and 116 are assembled to form the lower water supply guide 110. The duct parts 112, 114, and 116 are arranged sequentially. The water channel P2 is defined in the duct parts 112, 114, and 116. The first duct part 112 is disposed outside the upper inner case 44. The second duct part 114 and the third duct part 116 are disposed in the lower inner case 42. The position and number of the second and third duct parts 114 and 116 may be variously changed according to embodiments.
[0064] The air washer according to this embodiment may further include a controller configured to control the humidification unit 30, the blower 60, and the display unit 70. During the operation of the air washer, the controller may control the humidification unit 30 and the blower 60 to be driven. The controller may control the display part D to display information about the operation of the air washer on the top cover 72 of the display unit 70.
[0065] The operation of the air washer with the above-stated construction according to the first embodiment of the present disclosure will be described. During the operation of the air washer, the controller may control the motor 36 of the humidification unit 30 and the motor 64 of the blower 60 to be driven. When the motor 36 of the humidification unit 30 is driven, the driving gear 35 may rotate the driven gear 36. When the driven gear 36 is rotated, the disk assembly, including the disks 31, is rotated.
[0066] Water may be uniformly supplied to the disks 31 according to the rotation of the disk assembly. When the motor 64 of the blower 60 is driven, air outside the air washer is suctioned into the outer case 10 through the air suction port 2. The suctioned air flows through a gap defined between the inner case 40 and the water tub 20, and then contacts the disks 31. The air, having contacted the disks 31, flows upward along the inner case 40. The air, having flowed upward along the inner case 40, passes through the filter 90 and the discharge grill 50 in turn. The air having passed through the discharge grill 50 is blown by the blower 60, and then flows to the air discharge port 4.
[0067] When the water level in the water tub 20 is lowered according to the operation of the air washer, the controller provides an alarm based on the water level to the display unit 70. At this time, it is possible to supply water to the air washer according to this embodiment even in a state in which the operation of the air washer is not stopped. In addition, it is possible to supply water to the air washer according to this embodiment without disassembling the outer case 10. It is possible for a user to supply water through the water supply port 73 of the air washer during the operation of the air washer such that the water tub 20 is replenished with the water. The water supplied through the water supply port 73 flows through the decoration part 120, the upper water supply guide 100, and the lower water supply guide 110 in turn, and is then stored in the water tub 20.
[0068] In the air washer according the present disclosure, it is possible to easily supply water through the water supply port of the display unit without disassembling the outer case. It is also possible to supply water even when the blower and the humidification unit are operating.
[0069] Water flows downward through the water supply port, whereby it is possible to minimize the likelihood that the water will be introduced into the display unit. The water supply port may be formed at the display unit, and the air discharge port is formed outside the display unit, whereby it is possible to improve the external appearance of the circumference of the display unit.
[0070] The water channel may be formed outside the inner case, whereby it is possible to prevent electric leakage of the blower, to which electricity is supplied.
