  And the drive shaft 24a in the rotating shaft 24 of the said rotary humidification filter 23 is provided in the part located in the said water tank 22 below the said air blower outlet 6 (namely, the other side regarding the drawing-out direction of the water tank 22). That is, one end of the rotating shaft 24 (that is, the end portion on the drive shaft 24a side) is a notch-shaped bearing portion 32 in which an upper portion formed on the side wall 22a on the rear side in the water tank 22 is opened (see FIG. The other end of the rotating shaft 24 (that is, the end on the side opposite to the driving shaft) is formed on the inner surface of the side wall 22b on the front side in the pulling direction in the water tank 22. It is pivotally supported with respect to the U-shaped groove 33 (see FIG. 4). If it does in this way, while being able to isolate | separate the vaporization type humidification element 3 from the filter motor 26 which is a drive source, and can remove easily from the main body case 1, the rotary humidification filter 23 can also be easily detached from the water tank 22.

  On the side of the water tank 22 in the pulling direction, the water tank 4 is detachably set, and a water storage section 34 for temporarily storing water from the water tank 4 is integrally provided. The water tank 4 is set in an inverted state with respect to the water storage section 34, and the water supply port 4 a of the water tank 4 is opened only when the water tank 4 is set in the water storage section 34. An opening / closing valve 35 is provided. Reference numeral 36 is a float switch for detecting that the water tank 4 disposed in the water storage section 34 is empty. In this way, the vaporizing humidifying element 3 and the water tank 4 can be pulled out integrally with the main body case 1.

In addition, the water storage part 34 and the water tank 22 are formed with a communication hole 37 on the side wall 22b on the front side in the drawing direction of the water tank 22 so that the water storage part 34 and the water tank 22 communicate with each other.

The water level L is such that the upper end of the rib 28 located at the lower end of the ribs 28, 28,... Provided on each plate 25 in the rotary humidifying filter 23 is immersed (see FIG. 4). That is, a part of the rotary humidification filter 23 is immersed in the stored water in the water tank 22, and the center of the flow of the indoor air W ₁ blown out from the fan 2 is the rotation center of the rotary humidification filter 23. It is configured to pass more on the outer peripheral side. In this way, it becomes possible to largest possible flat portion 25b around the axial center 25a of each plate 25 is formed, a flow of room air W ₁ becomes smooth. Although the flat portion 25b is not immersed in water, the water pumped up to the ribs 28, 28,... Spills in the process of moving the ribs 28, 28,. Since the flat portion 25b is wetted, the entire surface of the plate 25 that is not immersed in the stored water in the water tank 22 is used for humidification, and the humidification efficiency is greatly improved.

Further, the rotation direction M of the rotary humidifying filter 23 is a direction in which the indoor air W ₁ blown out from the fan 2 is greeted. In this way, indoor air W ₁ that is blown out from the fan 2, it becomes possible to contact the rotating humidifying filter 23 immediately after leaving the the stored water in the water tank 2, to improve the humidification efficiency to room air W ₁ The pressure loss in the rotary humidifying filter 23 can be made as small as possible (the indoor air W ₁ blown out from the fan 2 is blown out toward the air outlet 6). In addition, the ribs 28, 28,... Face downward at the portion where the humidified air W ₂ flows. Therefore, it is also possible to prevent water droplets from getting on the humidified air W ₂ and scattering to the air outlet 6 and other parts.

  Further, a humidified air passage 38 communicating with the air outlet 6 is formed between the fan cover 7 and the main body case 1.

In the drawing, reference numeral 39 denotes a sealing rib that seals the discharge port 10 of the fan 2 and the outside of the main body case 1, and 40 denotes room air W ₁ blown from the fan 2 and the humidified air passing through the rotary humidifying filter 23. A sealing rib 41 for sealing the flow path with the humidified air W ₂ is an operation panel provided on the upper surface of the main body case 1.

  In the humidifier configured as described above, the following operational effects can be obtained.

Then, the indoor air W ₁ sucked from the air suction port 5 of the main body case 1 is blown out from the discharge port 10 of the fan 2. The indoor air W ₁ is heated to an appropriate temperature in the process of passing through the heater unit 14 and then supplied to the outer peripheral side from the rotational center of the rotary humidifying filter 23.

  On the other hand, a part of each plate 25 of the rotating humidifying filter 23 rotated at a low speed is immersed in the stored water in the water tank 22, and the portion exposed from the stored water by the rotation also gets wet with the water as described above. Yes.

Humidification is performed in the process of passing the indoor air W ₁ blown from the fan 2 on the outer peripheral side from the rotation center of the rotary humidification filter 23 in this state. Therefore, the power for driving the rotary humidifying filter 23 can be reduced, and the humidifying ability can be maximized. As described above, since the indoor air W ₁ blown from the fan 2 is heated to an appropriate temperature by the heater unit 14 and then supplied to the rotary humidifying filter 23, it is attached to the rotary humidifying filter 23. Evaporation of water is promoted and humidification efficiency is improved.

The humidified air W ₂ obtained as described above flows in the axial direction of the rotary humidifying filter 23, passes through the humidified air passage 38 formed between the fan cover 7 and the main body case 1, and passes through the air outlet 6. Blows into the room and keeps the room in a proper humidity environment. Therefore, the entire air flow in the main body case 1 can be made smooth.
