When the water surface reaches the water inlet of the cap 78, air stops flowing into the water supply tank 70, the air A in the water supply tank 70 is reduced in pressure, the supply of water W is stopped, and the water surface is constantly set at the set height. Is to be kept.

As described above, when the water W is supplied to the heating water tank 60 and the user starts operating the humidifier 50, the heating water tank 60 is heated by the electric heater 66 attached to the bottom of the heating water tank 60, and the water is heated. W boils and evaporates, and steam S passes through the steam outlet tube 90 and, as described above,
The air is further discharged to the outside of the humidifier 50 to humidify the room. In this case, as described above, since the air is supplied from the vent 92 provided in the lower part of the steam outlet tube 90, the steam S can be smoothly released.

Although not shown in the drawings, the conventional humidifier is provided with a hygrometer and a setting unit, which are set so that the indoor humidity can always be maintained at a suitable value. When the remaining amount of water in the water supply tank 70 becomes low, a predetermined indicator light flashes to urge water supply, or the heating circuit is automatically cut off. Further, the electric heater 66 of the heating water tank 60 is provided with various safety functions such as attaching a temperature fuse.

[0012]

As described above, in the conventional humidifier, a plurality of vents are provided at the lower portion of the steam outlet tube in order to smoothly release steam. However, when water is boiled in the heated water tank, the water in the heated water tank foams, and the water that has popped out from this vent may leak out. In addition, as described above, a structure is provided in which the steam outlet cover is attached to the outlet to prevent the condensation water from dripping. Water can leak from the vents. If the position of the air vent is provided above the steam outlet tube as a countermeasure against this, there is a new problem that the air permeability in the steam outlet tube is deteriorated and the efficiency of releasing steam is reduced. On the other hand, in the conventional humidifier, a receiving stand for receiving water leakage is provided on the outer edge of the heated water tank, but the shape of the upper surface is flat and insufficient for receiving water leakage.

As the water supplied to the heating water tank, tap water is used in ordinary ordinary households.
Minerals such as Mg are contained, and if water leakage from the vent is left, the splashed water droplets will be removed around the heated water tank,
When it enters the gap between the steam outlet tube and the heating water tank and evaporates at that location, these mineral components precipitate as salts such as calcium carbonate and magnesium carbonate.

If this is left for a long period of time, the precipitated salts will be stacked and the gap will be widened, and as a result, the water in the heated water tank will leak from this gap, and the waterproofness of the humidifier will be deteriorated. Is assumed. An object of the present invention is to solve the above problems (problems) and to provide a humidifier with improved waterproofness.
