<p>A humidifier which creates a visually entertaining helical flow of mist generally includes a base unit defining a reservoir for holding a quantity of water, a water tank supported on the base unit for supplying water to the reservoir, a humidification device, such as an ultrasonic transducer, in communication with the reservoir for vaporizing the water held in the reservoir to produce a mist, a vortex unit supported on the base unit and a nozzle and a vortex creator positioned in the vortex unit. The vortex unit has an opening disposed above the base unit reservoir to permit the mist produced by the humidification device to rise upwardly into the vortex unit. The nozzle is positioned adjacent the mist opening for introducing a carrier medium flow into the vortex unit and the vortex creator is positioned above the nozzle and the mist opening for diverting the upwardly rising mist from the reservoir into the carrier medium flow from the nozzle and directing a combined mist and carrier medium flow into a helical path within the vortex unit.</p> |
