PURPOSE:To prevent vapor generated from an apparatus from adhering to the peripheral part and dew condensation by providing a heater on a sucking material placed in at least an exhaust path of vapor. CONSTITUTION:When hot water 3 stored in a hot water storage container 2 is in a boiling state, vapor 4 passes through a reservoir 16 of hot water vapor passes through a vapor exhaust path 10 provided on a space part of a cover main body 7 and a vapor cut-off inner cover 8 and reaches a vapor exhaust port 11, and exhausted into the open air. In this case, vapor is sucked by a sucking material 9 placed in the peripheral part of the vapor exhaust path 10, therefore, in the case of vapor generated at the time of boiling of hot water of about three minutes in the vapor exhaust port 11, it becomes an extent that it is scarcely observed with eyes. Also, by constituting the heater so that heating of a heater 65 is started as soon as boiling is ended, a temperature of a sucking material 59 is further raised by condensation latent heat conducted from a vapor cut-off inner cover 58 and heating by a heater 65, and its sucking force is recovered in a shorter time. |
