PROBLEM TO BE SOLVED: To provide a natural vaporization type humidifier equipped with an air-conditioner without using any electric part by providing a water feed valve to open through operation of a thermally-actuating device when the temperature of heated air exceeds a prescribed value and close when it is below the prescribed value. SOLUTION: A water feed valve 23 is opened through operation of a thermally-actuating device 22 when the temperature of air flowing through a heat-exchanger 4 is increased to a prescribed value and closed when it is below the given value. When a wax thermo is used as the thermally-actuating device 22, the wax thermo is expanded and a spindle 22-1 is advanced. When the temperature of air flowing through the heat-exchanger 4 is increased to a prescribed value, an valve element 28 is pressed down against urging of a spring 29 and the water feed valve 23 is opened. When the wax thermo is contracted and the spindle 22-1 is moved backward, the water feed valve 23 is closed through urging of the spring 29. This constitution eliminates a fear of leak occurring and dissolves a problem on malfunction due to the error of wiring. |
