Abstract
A portable appliance includes a humidifier and a heated scent mechanism. The heated scent mechanism includes a scent generator that harvests excess heat produced by a liquid heating chamber, or heat produced as a byproduct of motor operation. The humidifier may be controllable such that the appliance can serve as either a humidifier or air-freshener, individually or simultaneously.
