DEHUMIDIFIER

PROBLEM TO BE SOLVED: To provide a small sized and simply structured dehumidifier that carries out a dehumidifying operation by virtue of a heat pump and a dehumidifying rotor, which dehumidifier is capable of efficiently carrying out the dehumidifying operation throughout a year by maintaining an amount of the dehumidification even in a low temperature condition. SOLUTION: The dehumidifier main body 1 having a suction port 2 and a discharge nozzle 4 is equipped with a heat pump 13 comprising a heat absorber 10 that absorbs heat from air supplied to it and a radiator 12 that radiates heat to the supplied air, a dehumidifying rotor 22 comprising a moisture absorbing section 26 that absorbs moisture of the supplied air and a regeneration section 27 that is caused to discharge the absorbed moisture by heating so as to be regenerated, a heater 23 for heating the regeneration section 27 and the air being supplied to the regeneration section 27, a first supply conduit 16 for taking in air from the suction port 2 to supply the air to the radiator 12 and discharging the air from the discharge nozzle 4, and a second supply conduit 17 for taking in air from the suction port 2 to supply the air to the heat absorber 10 and discharging the air from the discharge nozzle 4. The dehumidifying rotor 22 is disposed so that at least a portion of the air supplied to the radiator 12 passes through the moisture absorption section 26 and at least a portion of the air supplied to the heat absorber 10 passes through the regeneration section 27.
