PROBLEM TO BE SOLVED: To provide a humidifier which is excellent in heat efficiency. SOLUTION: An inner case 13 and an outer case 14 are arranged above a humidifying rotor 12, and an inner humidifying passage 15a is made inside the inner case 13, and an outer humidifying passage 15b is made between the outer face of the inner case 13 and the inner face of the outer case 14. A humidifying passage 15 is constituted of the above inner humidifying passage 15a and the outer humidifying passage 15b. The upper inner inner humidifying passage 15a is provided with a heater 16. In the above constitution of humidifier, the inner heater 13 is heated by the radiant heat of the heater for heating the air passing through the inner humidifying passage 15a and the heated hot air, but this heat is recovered by the air passing through the outer humidifying passage 15b. Accordingly, for the heat of the above heater 16, the quantity of it to be discharged out of the humidifying passage 15 is suppressed, and the heating efficiency of the heater 16 can be enhanced. |
