PURPOSE:To prevent power supply and interruption for heating from being repeated by providing a control circuit in which the power supply for heating is interrupted to turn indicator means on and off based upon an unload boiling state detection signal and power supply interruption and flashing operations are released by operation of an operation switch after a water tank is supplied with water. CONSTITUTION:With operation of a heating control switch a control circuit 60 controls power supply to a heater line by a signal from a switch circuit 56 to heat water in a heating pipe 36 for production of vapor, the vapor is in turn exhausted through an exhaustion outlet 48 to moisten the interior of a room. With an unloaded boiling signal inputted, power supply to a heater 18 is interrupted with a moistening mode indicator LED 30 being flashed, whereby a user is informed that water is exhausted and the indication is controlled until the moistening control switch is again operated. With water supply to a water tank 33 the heating pipe 36 is cooled the unloaded boiling signal is interrupted. With the moistening control switch operated, moistening operation is restarted and the moistening mode indicator LED 30 is lighted. With the operation of the moistening control switch without the water supply to the water tank 33, the moistening mode LED 30 is exhausted. With re-operation of the moistening control switch without the water supply the moistening mode indicator LED 30 is again flashed. |
