Patent ID: 8763994

Claim:
An ultrasonic air humidifying apparatus comprising: (A) a U-shaped air/water chamber, a U-shaped cover securable over a U-shaped recess, a deflector cover secured to a back plate, and a deflector secured to said air/water chamber; (B) said U-shaped recess housing electronic components including a fan, a fan motor, a step-down transformer having a single primary winding and a single secondary winding with taps located only at the ends of said windings, and a circuit board, said fan positioned in proximity to an upper air opening in a transverse wall; (C) a lower air opening in said transverse wall having a filter to enable said fan to withdraw air through said recess, said electronic components being connected to a 110 volt AC supply by a series of electrical cords extending through a conduit opening in said lower transverse wall; (D) at least one piezoelectric transducer in said air/water chamber, said piezoelectric transducer having a low water level sensor; (E) first and second ducts adjacently positioned alongside one another with said first duct extending into said second duct, said first duct being coupled to said upper air opening, a corrugated bottom surface of said second duct being wider than said first duct, and an O-ring gasket positioned between said second duct and said deflector; (F) said air/water chamber in connection to a house water line by a water feed line and a water drain line, each of said water feed and drain lines being equipped with a solenoid valve and fed through a conduit opening said in the lower transverse wall and coupled to said air/water chamber at said upper transverse wall adjacent said back plate; wherein said air/water chamber is equipped with a water level control system comprising a low water level sensor positioned at 0.25 to 0.5 inch, a float switch positioned at 1.75 to 2.0 inches, and an overflow sensor 2.5 to 2.75 inches above said piezoelectric transducer and said feed line solenoid valve is in communication with said low water level sensor and the float switch, and said drain line solenoid valve communicates with said overflow sensor so said low water level sensor, float and piezoelectric transducer can be triggered to deactivate said the piezoelectric transducer.
