PURPOSE:To perform a substantial reduction of an amount of transmitted heat to a water supplying tank and enable a stable keeping of an amount of fed water from the water supplying tank to be carried out by a method wherein a thermal insulating spacing is arranged between an atomization cylinder and the water supplying tank and air is blown into the thermal insulating spacing to discharge waste heat. CONSTITUTION:As water in a heating boiler 2 heated by a heater 5 is boiled up, the water ascends within an atomization cylinder 8 as particles of water vapor. Concurrently, air from a blower 6 is flowed at an aeration port 8a of the atomization cylinder 8a and discharged through a blowing port together with particles of water vapor. At this time, an aeration passage in the blower device passes through an opening 3b formed in a partition wall 3, flows in a thermal insulating spacing 12 enclosed by the atomization cylinder 8 and an enclosing wall 10. At this time, air in the thermal insulating spacing is discharged out of the device. In particular, the thermal insulating spacing 12 and the enclosing wall 10 are present between the atomization cylinder 8 and the water supplying tank 11, so that the heat is discharged through the thermal insulating spacing 12 and a transmitted heat from the atomization cylinder 8s is reduced and then the water supplying tank 11 can be kept at its normal temperature. Accordingly, a bad influence from the transmitted heat toward the water supplying tank can be eliminated and then a stable water supplying from the water supplying tank can be continued. |
