SOLUTION: A projected heat radiating body 6 is provided on the bottom surface of a water tank 2 provided in a main body 1 while a heat diffusion preventing cylinder 7 is equipped around the heat radiating body 6. Water, supplied from a tank 3, is sent into the heat radiating body 6 through a water tank 2. The heated water is changed into steam and is sent into a room together with air from a fan motor 8. Hot-water, heated by the heat radiating body 6, is diffused into the water tank 2 through convection, however, the heat will never be released to the circumference by the diffusion of the hot-water since the heat radiating body 6 is partitioned from the circumference thereof by a diffusion preventing cylinder 7. On the other hand, a heat generating body 9 is received in the heat radiating body 6 whereby the released amount of heat is reduced.  Further, impurities in the water adhere to the surface of the heat radiating body 6 gradually, however, the surface of heat radiating body 6 has a projected configuration whereby the adhered impurities can be cleaned easily.
