In a combination type humidifier having a heater and an ultrasonic vibrator, an art for preventing the ultrasonic vibrator from being thermally damaged due to a heat produced by the heater is disclosed. First, a current humidity of a space, a water temperature of a humidifying chamber and a target humidity set by a user are detected. When the current humidity is higher than the target humidity, a fan motor begins to operate for a rapid heat loss. Otherwise, when the target humidity is higher than the current humidity, an error message concerning the setting of the target humidity is displayed and the fan motor is driven for a predetermined time. The heater is controlled so that the water temperature of the humidifying chamber is kept below the limit temperature by using a result of comparing the water temperature of the humidifying chamber with a limit temperature that is set for protecting the ultrasonic vibrator while the ultrasonic vibrator and the heater are simultaneously operated by a user's selection. When a user selects a turbo mode, the turbo mode is changed into a mode in which a quantity of produced vapor is less than in the turbo mode, and then the ultrasonic vibrator is operated. |
