1. In combination with a heated air duct having an outer side wall, a humidifier mounted on said wall, said humidifier comprising a housing having a nozzle at one end thereof inclined downwardly, said nozzle having an axial water passageway therein provided with a valve seat at the lower end thereof, a plunger mounted in the nozzle for reciprocatory movement therein and having a valve head adapted to cooperate with said valve seat to seal off the lower end of the nozzle, electromagnetic means carried by the housing and operatively associated with the plunger for actuating said plunger to change the position of the valve head with respect to its seat, said side wall having an opening with which the nozzle is operatively associated to move a stream of water downwardly into the air duct when the valve is oiT its seat, and a target mounted within said air duct in the path of the stream ejected from said nozzle to thereby atomize the water and deliver it to the heated air stream, said nozzle being self-draining due to its inclined position.
