【Example】

Embodiment 1 FIG. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a cartridge type water tank,
Reference numeral 2 denotes a water outlet 3 which is opened and closed by a valve 12 which will be described later. A tank cap 4 attached to the water tank 1 is supplied with water in the water tank 1 via the tank cap 2 and maintained at a constant water level. Water receiving part, 6 is water receiving part 4
Is supplied through a rubber hose 5 to the evaporating dish, 7 is a heating element such as an electric heater for heating the evaporating dish 6, and 8 is an evaporating dish 6 when water in the evaporating dish 6 heated by the heating element 7 is vaporized. A residue adsorber 10 for adsorbing the residue deposited therein is a vapor discharge port for discharging the vapor guided by the vapor guide tube 9 adjacent to the evaporating dish 6 to the outside. FIG. 2 is a sectional view showing the tank cap of the humidifier of the present invention. In the figure, reference numeral 11 denotes a movable shaft provided on the tank cap 2;
Reference numeral 2 denotes a valve fixed to one end of the movable shaft 11, and reference numeral 12 denotes an urging spring for urging the movable shaft 11 so as to always push the movable shaft 11 downward, and normally acts to close the water outlet 3 by the valve 12. Numeral 14 denotes a natural silencer attached to the tank cap 2 and has a plurality of openings 15a, 15b with a difference in elevation.
Is formed on the side surface, and a slit-shaped perforation 1 is formed on the top surface.
A protrusion 16 having a side surface 6a is provided.

[0013] The evaporating dish 6 is heated by the heating element 7 to convert water in the evaporating dish 6 into steam. Residues such as calcium precipitated when water is vaporized are adsorbed on the surface of a residue adsorbent 8 vertically disposed in the evaporating dish 6. The steam generated by the evaporating dish 6 is discharged to the outside through the steam discharge port 10 through the steam guide tube 9. When the water in the evaporating dish 6 evaporates and the water level drops, the water level in the water receiving part 4 also drops, and when the water level drops to a certain level, a pressure difference between the inside and outside of the water tank 1 is generated. Water in tank 1 and water tank 1
The force to replace the outside air works. At this time, an opening 15 having a height difference of the silencer 14 covering the water outlet 3.
When water passes through the openings 16a of the projections 16a and 15b, a pressure loss is generated. Therefore, the flow velocity of the water is greatly reduced, and the interference between water and air at the water outlet 3 is suppressed, which is generated. Reduces junk noise.

The slit-shaped opening 16a formed on the side surface of the projection 16 provided on the top surface prevents water supply failure due to surface tension of water and water supply failure due to clogging caused by impurities such as dust. It also has the function of performing

FIG. 3 is an assembly view showing the residue adsorber 8.
By dividing the conventional two sheets into one sheet and folding it in two from the central portion, a double surface area is secured while maintaining substantially the same vertical and horizontal dimensions. In addition, the strength of the bent portion is increased, and the strength is increased by doubling the thickness, so that the stability is good even when installed vertically, and the residue adsorbent 8 does not fall down in the evaporating dish 6. . Reference numeral 8a is a through hole formed in the residue adsorber 8 to improve the flow of water.
