Further, an evaporating dish 6 is connected to the water supply port 18 of the check valve mechanism 16 of the water receiving unit 5 via a rubber hose 26 and generates water vapor by heating the heating body 8 from the water supplied from the water receiving unit 5. A steam guide tube 9 is provided above the evaporating dish 6 to guide the water vapor upward.
In addition, since the truncated cone-shaped hot water amount reducing member 7 formed of a hot water-resistant resin (for example, polypropylene resin) for reducing the amount of hot water in the evaporating dish 6 is disposed in the evaporating dish 6, the top of the hot water amount reducing member 7 is It is detachably attached so as to hang from the lower part of the steam guide tube 9.
The steam guide tube 9 is provided with a hot water reservoir 9a having a volume that can be accommodated in the event that the main body falls down, and the outer periphery of the hot water reducing member 7 has a shape that follows the shape of the hot water reducing member 7. The evaporation residue adsorbing body 13 is arranged in a state where it floats about 10 mm from the bottom surface of the evaporation dish 6.
For example, polypropylene non-woven fabric is used as the material of the evaporation residue adsorbing body 13.

  An air guide cylinder 12 for guiding the air taken in and sent out from the air inlet 10 by the blower fan 11 is provided at the upper part of the steam guide cylinder 9, and the steam and air guide sent from the steam guide cylinder 9 are provided. A mixing chamber 14 for mixing the air sent from the cylinder 12 and a blower outlet 15 for releasing the steam from the mixing chamber 14 to the outside are provided.

Next, the attachment and detachment of the hot water reducing member 7 to the steam guide tube 9 will be described with reference to FIGS.
FIG. 3 is an exploded configuration diagram of the steam guide tube 9, the hot water amount reducing member 7 and the evaporation residue adsorbing body 13, and FIGS. 4 and 5 are attachment explanatory views of the hot water amount reducing member 7.
When attaching the hot water quantity reducing member 7, the hot water quantity reducing member 7 is locked to the steam guide tube 9 after the evaporation residue adsorbing body 13 is covered. When locking, the rib 7a provided on the upper part of the hot water reducing member 7 as shown in FIG. 5 is inserted into the hole 9b provided on the lower part of the steam guide tube 9, and the hot water reducing member 7 is shown in FIG. Is rotated in a circumferential direction by a predetermined angle (90 ° in this case) to be locked by a key configuration. When removing the hot water amount reducing member 7 from the steam guide tube 9, the rib 7 a of the hot water amount reducing member 7 is returned to the original angle and taken out from the hole 9 b of the steam guide tube 9.

Next, the operation of the first embodiment configured as described above will be described.
When the water tank 2 is set in the main body 1, the water in the water tank 2 is supplied to the water receiving portion 5 through the water outlet 4 provided in the tank cap 3 and is held at a constant water level by the tank cap 3. In the normal operation, the check valve mechanism 16 below the water receiving unit 5 has the check valve 22 opened by the dead weight of the sphere 25, and the water in the water receiving unit 5 passes through the water supply port 18 and the rubber hose 26 to evaporate the dish 6. Water is supplied.

The water level in the evaporating dish 6 is the same as that of the water receiver 5 and is maintained at a height of 50 to 60 mm from the bottom of the evaporating dish 6. And since there is the hot water amount reducing member 7 in the evaporating dish 6, the absolute amount of the hot water in the evaporating dish 6 can be reduced as compared with the case where there is no hot water reducing member 7.
Further, the evaporation residue adsorbing body 13 provided on the outer periphery of the hot water amount reducing member 7 adsorbs the evaporation residue generated by evaporating the water in the evaporation dish 6 to the evaporation residue adsorbing body 13.

  The water vapor generated when the water in the evaporating dish 6 is heated by the heating body 8 is guided upward by the steam guide tube 9. On the other hand, air from the air inlet 10 is guided to the air guide cylinder 12 above the steam guide cylinder 9 by the blower fan 11. In the mixing chamber 14, the air guided by the air guide cylinder 12 and the steam guided upward by the steam guide cylinder 9 are mixed and discharged to the outside from the outlet 15.

  Further, when the hot water quantity reducing member 7 is contaminated with evaporation residue due to use of a humidifier, it is removed from the steam guide tube 9 and cleaned, and the evaporation residue adsorbing body 13 is periodically cleaned (boiled). Do.

Next, the operation when the humidifier is turned over in the lateral direction will be described with reference to FIGS.
FIG. 6 is a cross-sectional view of the evaporating dish when the humidifier is turned over in the horizontal direction, and FIG. 7 is a cross-sectional view of the water receiving portion when the humidifier is turned over in the horizontal direction.
As shown in FIG. 6, the hot water in the evaporating dish 6 always flows into the hot water reservoir 9a provided in the steam guide tube 9 when it falls down, and the hot water having a temperature close to 100 ° C. remains as it is. There is no outflow.
Further, as shown in FIG. 7, since the spherical body 25 is detached from the disc 23 of the valve shaft 21 of the check valve mechanism 16 of the water receiving portion 5 when it falls, the check valve 22 pressed by the coil spring 24 is removed. Thus, the water supply port 18 is closed, and hot water does not flow back from the evaporating dish 6 to the water receiving unit 5, and hot water does not flow out from the water receiving unit 5.

  As described above, according to the present embodiment, the hot water amount reducing member 7 is interposed in the evaporating dish 6, so that the absolute amount of hot water in the evaporating dish 6 is smaller than when the hot water amount reducing member 7 is not installed. Therefore, the volume of the hot water reservoir 9a of the steam guide tube 9 can be reduced, the outer shape of the main body is smaller, and hot water can be prevented from flowing out of the machine body when the main body falls down.

  Moreover, by forming the hot water amount reducing member 7 in the shape of a truncated cone, a gap with the wall surface of the evaporating dish 6 can be taken, and the bursting sound of bubbles at the time of boiling can be reduced. Moreover, since the hot water amount reducing member 7 has a thin water surface portion, the evaporation area can be increased.

  Moreover, since the material of the hot water reduction member 7 is a resin having hot water resistance, it is light and easy to handle.

  Moreover, since the hot water amount reducing member 7 is made detachable from the steam guide tube 9, when the hot water amount reducing member 7 is contaminated with evaporation residue or the like, it can be removed from the steam guide tube 9 and cleaned.

  Further, since the evaporation residue adsorbing body 13 is provided on the outer periphery of the hot water amount reducing member 7 so as to follow the shape of the hot water amount reducing member 7, it is necessary for the user to periodically clean the evaporation residue adsorbing body 13, and Even if the strength of the material is lost every time and the shape tends not to be maintained, the evaporation residue adsorbing body 13 is caught on the member 7, so that even after repeated washing, it will fall out of the member 7 and buckle and shape. You won't lose it.

  Further, since the evaporation residue adsorbing body 13 is attached in a state of being floated by a predetermined distance from the bottom surface of the evaporation dish 6, it is possible to prevent the evaporation residue adsorbing body 13 from adhering to the evaporation dish 6 bottom surface together with the evaporation residue.
