Furthermore, the water tank part 9 is provided in the lower part of the main body 3 so that attachment or detachment is possible, and can be pulled out in the direction orthogonal to the rotating shaft 6C. Located at the approximate center between the first humidifying filter 6A and the second humidifying filter 6B, a diverting convex portion 10 is erected in the water tank portion 9, and the diverting convex portion 10 has a tip above the water level of the water tank portion 9. It is protruding.

  A first passive gear 13A is fixed to the rotating shaft 6C of the first humidifying filter 6A disposed on the front side of the water tank unit 9 and protrudes to the left side of the water tank unit 9.

In addition, the filter medium impregnates or apply | coats the solution which consists of a talc and a binder on the surface of a foaming urethane base material.

  The first humidifying filter 6 </ b> A and the second humidifying filter 6 </ b> B are arranged so that the rotating shaft 6 </ b> C is horizontal and perpendicular to the rotating shaft of the blower 4.

  In the above configuration, when the humidifier is operated in a state where water is supplied from the water supply tank 8 to the water tank section 9 and the lower ends of the first humidifying filter 6A and the second humidifying filter 6B are immersed, the air blowing means 4 causes the main body from the suction port 1. The indoor air introduced into the interior 3 is humidified by passing through the first humidifying filter 6A and the second humidifying filter 6B which are rotating while being immersed in the stored water in the water tank section 9, and the humidified air is The air is blown into the room from the air outlet 2 via the 1 humidifying channel 7A and the second humidifying channel 7B.

  Here, the indoor air introduced from the suction port 1 is branched into the first humidifying filter 6A and the second humidifying filter 6B when the air blowing capacity of the air blowing means 4 is the same as the conventional one, Since the wind pressure is distributed to each of the first humidifying filter 6A and the second humidifying filter 6B and the pressure loss is greatly reduced, the blowing efficiency of the blowing means 4 is improved, the air volume is increased, and the noise is reduced.

The first drive motor 11A and the second drive motor 11B are arranged on the main body 3, respectively. As a result, the first humidifying filter 6A and the second humidifying filter 6B, which are connected to the first driving motor 11A and the second driving motor 11B and rotated, rotate in opposite directions, and the moisture adhesion state of the humidifying filter is changed. Since it becomes substantially the same for the blown airflow branched from the discharge part 4A of the blowing means 4, it can be humidified under substantially the same conditions, and a stable humidification operation can be performed. Further, when the water tank 9 is moved and pulled out, the first passive gear 13A, the second passive gear 13B, the first drive gear 12A, and the second drive gear 12B can be brought into contact with and separated from each other. The water tank 9 can be easily attached to and detached from the main body 3 with the humidifying filter 6 </ b> A and the second humidifying filter 6 </ b> B housed in the water tank 9.
