With the configuration of the third means, it can be discriminated whether the humidifying means of the humidifier in operation is in operation or stopped by whether the light emitting diode is blinking or continuously lit. The operating state can be seen at a glance.

Further, according to the constitution of the fourth means, when there is an abnormality in the open state or the short state in the system for detecting the room temperature or the indoor humidity, the state is turned off, no abnormal value is displayed, and in the normal state. Since the state is different from the lighting state of, the user can recognize at a glance that the humidifier has some abnormality.

Further, according to the configuration of the fifth means, the display range of the indoor humidity can be automatically changed according to the high or low of the humidity set by the user's preference, so that the comfortable range of the humidity set by the user is set. On the other hand, whether or not the current humidity matches can be easily determined from the lighting position of the light emitting diode.
