This is done by sucking in from the suction port to dehumidify and dry, and by blowing out the dehumidified dry air into the room from the outlet, so that the bathroom can be used as a drying room for clothes such as laundry. There is.

Conventionally, in this type of dehumidifying / drying device,
Circulating air that blows dry air after the humid air in the room that has been sucked in through the suction port passes through the rotary dehumidifying element provided in the case body to cause the moisture to be adsorbed into the room through the air outlet. In addition to the forced circulation mechanism, the high temperature air is sent to the rotary dehumidifying element to which moisture is adsorbed, so that the rotary dehumidifying element desorbs water and regenerates the rotary dehumidifying element.
