Abstract
A method for controlling a heating of a heater in a heating-type humidifier in which both a heating amount and a heating ON/OFF period is controlled on the basis of a present room temperature, is disclosed. A sensed present humidity is compared with an objective humidity which is set by a user. When the present humidity is greater than or equal to the objective humidity, whether or not water exists in a water tank of the humidifier is determined. When the water does not exist in the water tank, an alarm is generated. When the water exists, a humidifying operation stops. When the present humidity is less than the objective humidity, the humidifying operation is executed while increasing both a heating amount and a heating ON period of the heater in proportion to the present room temperature. As a result, the arrival times at the states of objective humidity are shortened.
