At this time, the pressing piece 18c formed on the sub-frame 18 presses the comb-shaped member 16 against the vaporization filter 15 side.

Next, the operation of the first embodiment of the present invention having the above configuration will be described. First, during normal humidification operation, the heater 4 is not energized, and only the blower fan 6 and the pump 10 are energized. As a result, the normal-temperature water in the water tank 2 is pumped by the pump 10 and guided to the shower port 12 through the water pipe 11. Then, the water guided to the shower port 12 is dispersed and the vaporized element 3
Is uniformly supplied to the upper portion of the vaporizing element 3, and flows down while permeating from the upper portion to the lower portion of the vaporizing element 3, permeates the entire vaporizing element 3, and is supplied extra. Water drops from the lower part of the vaporization element 3 and returns to the water tank 2. On the other hand, by the operation of the blower fan 6, dry air in the room is sucked in from the suction port 7,

It is supplied to the vaporizing element 3. This operation is repeated until the sterilization operation is completed.

Here, during the humidifying operation and the sterilization operation, water or hot water is supplied to the vaporizing element 3 from above, so that a plurality of rectangular humidifying elements 3a as shown in FIG. It cannot be used because it does not have a sufficient strength simply to hold the shape with a pair of holders 3b or the like. Therefore, as shown in FIG. 5, if the vaporization filter 15 made of a nonwoven fabric is folded in a wave shape, and the interval between the folding ridges is fixed by an adhesive 19 made of resin so as to keep the interval, Since the shape of the vaporization filter 15 itself can be maintained to some extent, it can be used for the time being. However, even in the configuration shown in FIG. 5, the shape retention of the vaporization filter 15 depends on the strength of the vaporization filter 15 itself and the adhesive 19 when immersed in hot water. There is a concern that the humidifier will collapse and stable humidification and heat sterilization of the entire vaporizing element 3 cannot be performed.

However, in the first embodiment, as shown in FIGS. 1 and 3, the vaporizing element 3 includes a vaporizing filter 15 having a water-absorbing property and a vaporizing filter 15 having a water-absorbing property. , A base frame 17 having a folded mountain support plate 17a for setting the vaporized filter 15 similarly bent in a wave shape, and a wave shape through the base frame 17 and the comb member 16. The evaporating filter 15 is composed of the base frame 17 and the sub-frame 18 for sandwiching and fixing the bent evaporating filter 15.

Further, since the pressing piece 18c formed on the sub-frame 18 presses the comb-like member 16 against the vaporizing filter 15, the comb-like member 16 is prevented from coming out or being displaced up and down. Fifteen
Can be more reliably maintained.

In the first embodiment, the comb-like member 1
Although the filter 6 and the vaporizing filter 15 are formed separately, the comb-like member 16 may be fixed to the filter 15 described below while bending the vaporizing filter 15 into a wave shape.
In this case, since the comb-shaped member 16 is integrally fixed to the vaporizing filter 15, the position of the comb-shaped member 16 does not shift in the vertical direction, and the shape of the vaporizing filter 15 can be more reliably maintained, and the assembling can be performed. It will be easier. Also,
Although two subframes 18 are provided, one subframe may be used.
