Abstract: A humidifying apparatus includes a nozzle and a base on which the nozzle is mounted. The nozzle has respective first and second air inlets, air outlets and interior passages for conveying air therefrom and thereto. The nozzle defines a bore through which air outside the humidifying apparatus is drawn by air emitted from the air outlets.

Abstract: Humidifying apparatus includes a chamber, and a water tank for supplying water to the chamber. A baffle located within the chamber divides the chamber into an inlet section and an outlet section, and guides water received from the water tank along the inlet section to the outlet section.
