Abstract: The present invention provides a humidifier for a refrigeration showcase comprising a plurality of ultrasonic vibrators for atomizing water, ultrasonic oscillation circuits provided for the vibrators respectively in corresponding relation thereto,and control means for varying the oscillation output of the oscillation circuit corresponding to at least one of the vibrators to control the amount of atomized water to be produced.

Abstract: A humidifier unit for use with a refrigerated display cabinet having a cooled air passage includes a body adapted to be mounted on an upper surface of the refrigerated display cabinet, a horizontally elongate atomizing water tank disposed in one side of the body and having a plurality of ultrasonic vibrators mounted on a bottom thereof and arrayed in a longitudinal direction, an air blower disposed in an opposite side of the body for supplying air drawn from a suction port into the atomizing water tank, and pipes angularly movably mounted on the atomizing water tank in coaction with the ultrasonic vibrators, respectively, for transferring a mist generated by the ultrasonic vibrators in the atomizing water tank and air from the air blower into the cooled air passage of the refrigerated display cabinet.

Abstract: An ultrasonic humidifier for atomizing water in a vessel by an ultrasonic oscillator and supplying atomized water with air into a room by a blower comprising a humidity sensor detecting the humidity in the room and a thermosensor detecting the temperature in the room. The operation of said ultrasonic oscillator is controlled in such a manner that the value of the detected humidity compensated by said thermosensor may be set for the desired value.
