An intake / drain port 72 is provided on the filter 6 side in front of the storage / drainage unit 71 in the rotation direction. When the storage / drainage unit 71 reaches below the filter 6 by the rotation of the rotating body 7, Water is introduced into the storage / drainage part 71 from the suction / drainage port 72 to store water, and when the storage / drainage part 71 reaches the upper part of the filter 6 by the rotation of the rotating body 7, the water in the storage / drainage part 71 is discharged from the suction / drainage port 72. Water is drained to the side surface of the filter 6 and water is applied to one side surface of the filter 6. Further, the water intake and discharge ports 72a and 72b of the two storage and drainage portions 71a and 71b adjacent to each other in the rotation direction of the rotating body 7 have different distances H from the rear end in the rotation direction, and the water intake and discharge ports 72a of the respective storage and drainage portions 71a and 71b. , 72b can be drained simultaneously. The water intake / drain port 72b having the short distance H of the water storage / drainage portion 71b is disposed closer to the rotation center than the water intake / drainage port 72a having the long distance H of the water storage / drainage portion 71a.

  A driving wheel 30 that drives the rotating body 7 in contact with the outer peripheral surface 75a is disposed at a position facing one circumferential direction of the outer peripheral surface 75a of the ring portion 75, and is interlocked and connected to the driving wheel 30. An electric motor 40 is attached to the support member 20.

  The dust collection filter 4 and the deodorizing filter 5 are formed in a rectangular parallelepiped corresponding to the intake port 11. Moreover, the water supply part 8a of the water supply container 8 is a cap having an on-off valve.

  In the humidifier configured as described above, the water in the water supply container 8 is supplied to the water tank 2 and the water tank 2 has a predetermined water level, and the electric motor 40 for the blower 3 and the rotating body 7 is driven. The humidifying filter 6 is disposed above the water level, the rotating body 7 has a lower water storage / drainage part 71 below the water level, and the lower water storage / drainage part 71 is immersed in water. Water is stored in the water storage / drainage part 71 from the water intake / drainage port 72 of the lower water storage / drainage part 71.

  When the electric motor 40 is driven, the rotating body 7 is rotated via the drive wheel 30, and a plurality of water storage and draining portions 71 provided in the circumferential direction on the ring portion 75 of the rotating body 7 are sequentially provided in the water tank 2. The water storage / drainage part 71 that has been immersed in water and stored in the water storage / drainage part 71 from the water intake / drainage port 72 of the immersed water storage / drainage part 71 moves to the upper side of the filter 6, so Water is drained from the water inlet / outlet 72 of the portion 71 to the upper side surface of the filter 6, and water penetrates into the upper portion of the filter 6. The water that has permeated into the upper part permeates the lower side of the filter 6 and the moisture absorbing sheet 62 between the filter main bodies 61 and 61 absorbs moisture. The moisture absorbed by the moisture absorbent sheet 62 spreads over the entire surface of the moisture absorbent sheet 62, and moisture penetrates from the moisture absorbent sheet 62 into the lower filter body 61 and penetrates the entire filter 6.

  In addition, by driving the blower 3, outside air (air in the living room) is sucked into the housing 1 from the air inlet 11, and a wind passage is generated between the air inlet 11 and the air outlet 12, and the odor in the outside air is deodorized. Foreign matter such as dust in the outside air is removed by the filter 5 and removed by the dust collecting filter 4. Further, the wind that has passed through the deodorizing filter 5 and the dust collection filter 4 passes through the filter 6 between the arms 74 of the rotating body 7 and the outer periphery of the ring portion 75. At this time, water permeating the filter 6 is vaporized, the wind passing through the filter 6 is humidified, and the humidified air is exhausted from the exhaust port 12 to the living room through the blower 3 to humidify the living room.

  As described above, the filter 6 is disposed above the water level of the water tank 2, the rotating body 7 is disposed on one side of the ventilation path of the filter 6, and the rotating body 7 is rotated relative to the filter 6 to rotate the water tank 2. Since the water inside is applied to one side of the filter 6 on the upper side of the filter 6, the filter 6 can be formed in a size having an area larger than the area of the rotating region of the rotating body 7, and the entire filter 6. Thus, water can be vaporized, and the humidifying ability of the filter 6 can be set large. Further, the water intake and discharge ports 72a and 72b of the storage and drainage portions 71a and 71b adjacent in the rotation direction of the rotating body 7 have different distances H from the rear end in the rotation direction, and the water intake and discharge ports 7272a and 72b of the adjacent storage and drainage portions 71a and 71b. Since the water can be drained simultaneously, the efficiency of water spraying to the filter 6 can be increased, and the water permeation time to the entire filter 6 can be shortened. Further, since the filter 6 is provided with a moisture absorbing sheet 62 between the filter bodies 61 and 61 stacked one above the other, the water applied to the upper filter body 61 penetrates along the moisture absorbing sheet 62 when penetrating downward. Water can be guided in the direction, and the permeation time of water into the entire filter 6 can be shortened.

  Moreover, since the driving wheel 30 for driving the rotating body 7 is provided around the outer periphery of the rotating body 7, the length of the air passage in the direction in which the wind passes through the filter 6 can be made relatively short, and the entire humidifying device Can be miniaturized.

  In the embodiment described above, the deodorizing filter 5 and the dust collecting filter 4 are provided and the air purifying function is provided. However, the humidifier according to the present invention has the deodorizing filter 5 and the dust collecting filter 4. The structure which eliminated can be sufficient.

  In the embodiment described above, the rotary body 7 is separated in the rotational direction and has a plurality of water storage / drainage portions 71. However, the number of the water storage / drainage portions 71 may be one. The number of parts 71 is not particularly limited. When the number of the water storage parts 71 is relatively small, the ring part 75 is eliminated, the water storage part 71 is provided at the tip of one or a plurality of arms 74, and a driving means such as an electric motor drives the rotation center part. It is good also as a structure.

  Further, in the embodiment described above, one water intake / drain port 72 is provided in the storage / drainage unit 71, but in addition, a plurality of water intake / drain ports 72 may be provided. In this case, it is preferable that the water inlet / outlet 72 is provided so as to be separated in the rotational direction of the rotating body 7 so that the amount of drainage is divided and drained little by little.
