1. An ultrasonic humidifier, which comprises:
- a vessel for holding water;
an ultrasonic oscillator for atomizing the water contained in the vessel;
a blower for supplying the atomized water to a room in which the humidifier is used;
a humidity sensor for detecting the humidity in the room, the humidity sensor providing an output signal representative of the humidity in the room;
a thermosensor for detecting the temperature in the room;
means for setting the humidity in the room to a desired value;
means for compensating the humidity in which the output signal of the humidity sensor is compensated by the thermosensor;
means for comparing the value of the humidity compensated by the humidity compensating means with the desired value of the humidity set by the humidity setting means, the comparing means providing a compared result;
means for controlling the operation of the ultrasonic oscillator in accordance with the compared result of the comparing means;
means for displaying the humidity in the room in response to the humidity compensated by the humidity compensating means; and
means for preferentially controlling the operation of the ultrasonic oscillator so that if the humidity is set at a desired value which exceeds a predetermined uppermost humidity setting, the ultrasonic oscillator will be operated continuously irrespective of the compared result obtained by the comparing means.

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.
