Abstract

Disclosed is a humidification device capable of satisfying both necessary and sufficient humidification abilities and energy conserving. A humidification filter unit is immersed into water and rotates to facilitate the absorption of water. When the time from stopping of the humidification operation to the restarting thereof is long and the amount of water absorption is insufficient, the humidification filter unit rotates continuously for a predetermined time when the humidification operation restarts, and then rotates intermittently. Meanwhile, when the time from stopping of the humidification operation to the restarting thereof is short and the amount water absorption is sufficient, the humidification filter unit rotates intermittently during the humidification operation. The rotating stop time of the humidification filter unit for each intermittent rotation is set depending on the air blowing quantity of a blower fan.

Claims6

Dependent claims

A humidification device, comprising:

a water storage unit configured to store water;
a filter unit which has water absorption properties and air permeability and is supplied with water from the water storage unit;
a blower configured to send air passing through the filter unit to an outside of a device;
a rotation driving mechanism configured to rotate the water storage unit or the filter unit to facilitate the supply of water to the filter unit or the absorption of supplied water into the filter unit;
and
a control unit configured to control an operation of the rotation driving mechanism,
wherein the control unit includes:
an intermittent control section configured to intermittently rotate the water storage unit or the filter unit;
a continuous control section configured to continuously rotate the water storage unit or the filter unit;
and
a determination section configured to determine whether or not the water storage unit or the filter unit rotates for a predetermined time or by a predetermined number from the beginning of the continuous rotation, when the water storage unit or the filter unit continuously rotates, this determination is made when a non-humidification time is a predetermined non-humidification time or less to determine whether an amount of water absorption in the filter unit is sufficient,
wherein when the determination section determines that the amount of water absorption is sufficient, the control unit switches from a control by the continuous control section to a control by the intermittent control section.
