<p>PURPOSE:To improve the operability and the dehumidifying efficiency by sticking a dehumidifying material and a water absorbing and holding material to the filter which is attachably/detachably disposed in the air flow generated by a blower. CONSTITUTION:A filter body 2 is disposed between air suction openings 3 and a blower unit 6 through an inserting hole 14 provided with a cover body 13, and the air sucked through the air suction openings 3 passes through the filter 11 and is discharged from blowing-out openings 4 by the blower unit 6. The filter 11 consists of polyester nonwoven fabric 16 stuck with polyacrylic acid high polymer material 17 which is dehumidifying, water absorbing and water holding material. Electrodes 21 are installed with such small distances between the front and rear surfaces of the filter body 2 that the electrodes are not brought into contact with the filter, but, when the filter 11 absorbs water and is swelled and the thickness of the filter 11 is increased, the electrodes 21 are brought into contact with the filter 11, and the electrodes constitute an alarm circuit to tell the exchange time of the filter 11. Thus, an efficient dehumidification is carried out with a simple structure.</p> |
