ABSTRACT:
An air humidifier used for regulating humidity in indoor spaces, such as residential flats, and in which the humidity has been produced by vaporizing water in a vaporizer. The problem in existing air humidifiers is the constant need to add water and the need of other maintenance, such as cleaning. In the air humidifier of the invention, these problems have been solved in the way that the air humidifier is connected to the water mains by means of a pipe. The water flow entering the vaporizer can be controlled with the aid of a valve, and after the water inflow has been stopped by the valve the heat stored in the walls of the vaporizer and in the electric resistance dries the vaporizer, while at the same time burning out the impurities in the vaporizer.
