Humidifier including a device for regulating the degree of humidification of the air flow

摘要

A method for supplying a mask (7) through which air flows with a regulated degree of humidification (m) is provided. The method comprises: providing a water reservoir (4) configured such that the air circulates in contact with the surface of water within the reservoir is charged with humidity; providing a heating device (3) for heating the water in the reservoir by circulating an electric current; measuring an average intensity (Iav) of the current passing through the heating device; and controlling of said average intensity (Iav) relative to a reference value (Iav) to obtain a degree of humidification (m) of the air that is independent of the ambient temperature (Ta). An apparatus for regulating the degree of humidification of air flow, as well as a heating humidifier including such a regulation device, are also provided.
