  • Publication number: 20240102673
    Abstract: A humidifier includes a housing, a humidifying rotor, and an irradiator. The housing is formed with an air passage through which air passes and a water storage tank configured to store water. The humidifying rotor extends over the air passage and the water storage tank. The humidifying rotor rotates so that a portion of the humidifying rotor having absorbed moisture from the water storage tank moves to the air passage and releases the moisture. The irradiator irradiates part of the humidifying rotor with ultraviolet light.
