BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will now be described in detail as examples based on the drawings. 1 is a sectional view of a humidifier according to the present invention, FIG. 2 is an explanatory view of a main part of a humidifier according to the present invention, (A) is a sectional view, (B) is a bottom view, and FIG. 4A is a cross-sectional view, FIG. 4B is a view taken in the direction of arrow A shown in FIG. 4A, and FIG. 4 shows another example of the humidifier according to the present invention. It is a principal part explanatory view, (A) is sectional drawing, (B) is the A arrow view shown in (A).

As shown in FIG. 1, reference numeral 1 is a humidifier main body, and the humidifier main body 1 stores a water supply tank 2 having a water supply cap 2a for discharging an appropriate amount of stored water, and water from the water supply tank 2. A water receiving tank 3, a heating tank 5 having a heater 4 for heating and boiling water, and a communication for communicating the water receiving tank 3 with the heating tank 5 to introduce water from the water receiving tank 3 to the heating tank 5. Pipe 7 and blower 8 for blowing air into the humidifier body 1
And an air outlet 9 provided with an air outlet nozzle 9a for mixing the air blown from the blower 8 with the vapor that has boiled and evaporated in the heating tank 5 and blows it out into the room.

The water receiving tank 3 contains an ion exchange resin 10 for softening hard water. Further, on the inner periphery of the lower portion of the heating tank 5, a housing portion 22 having a step portion 21 and protruding inward and having a smaller diameter than that of the heating tank 5 is continuously formed, and a scale is installed in the housing portion 22. Cloth filter for adsorption
While 11 is detachably mounted, on the outer periphery of the upper portion of the heating tank 5, an evaporation tray 23 for receiving and evaporating the hot water boiled and scattered in the heating tank 5 is detachably mounted in a heat transfer manner. There is.

As an example, as shown in FIGS. 3 (A) and 3 (B), the accommodating portion 22 is formed in a tubular shape with its upper part open, or as another example, FIG. 4 (A). Also, as shown in FIG. 4B, a plurality of ribs 22a may be formed on the inner periphery of the lower portion of the heating tank 5 so as to project at predetermined intervals.

Since the accommodating portion 22 is configured as in the above-described example or another example, it is not necessary to provide an inner pot inside the heating tank 5, so that the structure is not complicated. It will be advantageous in terms of cost.

The upper portion of the tip of the accommodating portion 22 is shown in FIG.
As shown in (A) or FIG. 3 (B), since the inclined portion 22b or the arc-shaped portion 22c inclined toward the inner peripheral surface side of the heating tank 5 is formed, the filter 11 can be smoothly moved from the portion. It can be installed.

The evaporation tray 23 is shown in FIG. 2 (A) and FIG.
As shown in (B), it is formed of synthetic rubber or synthetic resin in a cylindrical shape with a bottom, a large through hole 23b is provided in the center of the bottom surface 23a, and the above-mentioned heating hole is provided on the periphery of the through hole 23b. An upwardly projecting annular convex portion 23c which is fitted into the upper edge portion of the tank 5 so as to be heat-conductively close to it, and an annular U-shaped groove 24 having a downwardly projecting annular section are provided on the outer periphery thereof.

With the above configuration, the operation will be described below. The water once received by the water receiving tank 3 from the water supply tank 2 and supplied to the heating tank 5 through the communication pipe 7 is heated and boiled by energizing the heater 4 provided in the heating tank 5. .

A part of the hot water heated and boiled in the heating tank 5 scatters on the outer periphery of the heating tank 5 and hits the inner wall of the evaporation tray 23 to be evaporated. The hot water that has not completely evaporated is temporarily stored in the U-shaped groove 24 formed in the evaporation tray 23 and then evaporated.

As a result, the scale component contained in the hot water evaporated from the evaporating dish 23 adheres to the evaporating dish 23, and the other part of the hot water boiled by the heating tank 5 is the filter 11. After the scale component is removed, it will be evaporated. Then, the evaporated vapors are mixed with the air blown from the blower 8 to be cooled, and then blown out into the room from the blowout port 9.

As described above, the scale component contained in the hot water evaporated from the evaporation tray 23 is the filter 11
Since it is attached to the evaporation tray 23, the scale can be easily removed by replacing the filter 11 once a year and removing the evaporation tray 23 for cleaning.

At this time, since the scale attached to the U-shaped groove 24 of the evaporating dish 23 has a curved bottom surface, the scale can be easily removed. Has become.

Although not shown, the filter 11 may be detachably attached to the accommodating portion 22 in a cylindrical shape so as to adsorb scale components.
Alternatively, it may be detachably attached to the accommodating portion 22 in a spiral shape so that the scale component can be more effectively adsorbed.

[0024]

As described above, according to the present invention,
The humidifier facilitates scale removal due to the cost-effective construction and facilitates scale removal work.
